        We have two reportable segments, Bruker Scientific Instruments (BSI), which represented approximately 90% of our revenues during the year ended December 31, 2017, and Bruker Energy & Supercon Technologies (BEST), which represented the remainder of our revenues. Within BSI, we are organized into three operating segments: the Bruker BioSpin Group, the Bruker CALID Group and the Bruker Nano Group. For financial reporting purposes, the Bruker BioSpin, Bruker CALID and Bruker Nano operating segments are aggregated into the BSI reportable segment because each has similar economic characteristics, production processes, service offerings, types and classes of customers, methods of distribution and regulatory environments.

BSI Segment

Bruker BioSpin Group

        The Bruker BioSpin Group comprises the Bruker Magnetic Resonance, Applied Industrial and Clinical, Preclinical Imaging and Service and Lifecycle Support Divisions and designs, manufactures and distributes enabling life science tools based on magnetic resonance technology. Magnetic resonance is a natural phenomenon occurring when a molecule placed in a magnetic field gives off a signature radio frequency. The signature radio frequency is characteristic of the particular molecule and provides a multitude of precise chemical and structural information. Depending on the intended application, we market and sell to our customers a NMR system or an EPR system (each as defined below).

        Bruker BioSpin also manufactures and sells single and multiple modality systems using MRI, PET, SPECT, CT and MPI (each as defined below). Bruker BioSpin's products, which have particular application in structural proteomics, drug discovery, pharmaceutical and biotechnology research and production, and food and materials science fields, provide customers with the ability to determine the structure, dynamics, and function of specific molecules, such as proteins, and to characterize and determine the composition of mixtures.

Table of Contents

        The majority of Bruker BioSpin's revenues are generated by academic and government research customers. Other customers include pharmaceutical and biotechnology companies; chemical, food and beverage, clinical and polymer companies; and nonprofit laboratories.

        During 2017, we launched a number of new products and technologies, including the next generation of NMR electronics consoles, new software and hardware for enhanced workflow solutions for NMR spectroscopy research and analysis and a new solution for the quantification of metabolites in urine using NMR.

        Bruker BioSpin Group's instruments are based on the following technology platforms:

•

NMR—Nuclear magnetic resonance;



•

EPR—Electron paramagnetic resonance;



•

MRI—Magnetic resonance imaging;



•

MPI—Magnetic Particle Imaging;



•

PET—Positron Emission Tomography;



•

SPECT—Single Photon Emission Tomography; and



•

CT—Computed Tomography.

        NMR is a qualitative and quantitative analytical technique that is used to determine the molecular structure and purity of a sample. Molecules are placed in a magnetic field and give off a radio frequency signature that is recorded by a sensitive detector. Analysis software helps to determine the molecular structure of the sample. The NMR technique is used in academia, pharmaceutical, biotechnology, food and beverage and clinical companies, and by other industrial users in life science and material science research.

        EPR is a process of absorption of microwave radiation by paramagnetic ions or molecules with at least one unpaired electron that spins in the presence of a static magnetic field. EPR detects unpaired electrons unambiguously, whereas other techniques can only provide indirect evidence of their presence. In addition, EPR can identify the paramagnetic species that are detected, which present information on the molecular structure near the unpaired electron and give insight into dynamic processes such as molecular motions or fluidity. Our EPR instruments are used for a wide range of applications, including advanced materials research, materials analysis and quality control.

        MRI is a process of creating an image from the manipulation of hydrogen atoms in a magnetic field. In the presence of an external magnetic field, atoms will align with or against the external magnetic field. Application of a radio frequency causes the atoms to jump between high and low energy states. MRI and magnetic resonance spectroscopy, or MRS, include many methods including diffusion-weighted, perfusion-weighted, molecular imaging and contrast-enhance. MRI offers high resolution morphologic information, as well as functional, metabolic or molecular information. Customers use our MRI systems in pharmaceutical research, including metabolomics, to study a number of diseases, including diabetes, neurology, oncology and cardiovascular disorders.

        MPI is a process of creating an image from magnetic particles administered to the body of an animal. The magnetic particles are manipulated in a combination of oscillating magnetic fields exhibiting a field free zone. The response of the particles allows a real time 3D data set acquisition of the whole body of an animal, showing the contrast agent distributing in and flowing through the body. This imaging modality is used to detect cardiovascular disorders.

        PET is a process of creating an image from positrons after administration of a positron emitting radionuclide to the body of an animal. Annihilation of the positron produces two photons which show an angle of 180° between them, distinguishing these photons from photons originating from other

sources. The PET tracer enriches in certain regions of interest within the body and gains molecular information from the animal in vivo. This has widespread applications, most importantly for oncology, inflammation, neurology and cardiovascular disorders, as well as metabolic disease, drug discovery and bone disease.

        SPECT uses a contrast agent containing radionuclides which directly emit single photons. The contrast agent enriches in certain parts of the body of an animal and generates images of the radionuclide distribution in the body. SPECT has widespread application in animal investigations in vivo, most importantly in oncology, neurology and cardiovascular disorders.

        CT is a technology based on X-rays which are used to generate a complete 3D data set. The most important applications are tissue sample analysis or non-invasive in vivo animal imaging. CT offers the highest spatial resolution of all preclinical imaging modalities and is especially useful to generate morphological information about the object or animal under investigation. CT is being used in a wide range of preclinical investigations such as bone-orthopedics, cardiovascular, pulmonary, oncology, metabolism and others.

Bruker CALID Group

        The Bruker CALID Group comprises the Bruker Daltonics, Bruker Detection and Bruker Optics Divisions. The Bruker Daltonics Division primarily designs, manufactures and distributes life science mass spectrometry, or MS, instruments that can be integrated and used along with other sample preparation or chromatography instruments.

        MALDI-TOF mass spectrometers utilize an ionization process to analyze solid samples using a laser that combines high sample throughput with high mass range and sensitivity. Our MALDI-TOF mass spectrometers are particularly useful for applications in clinical diagnostics, environmental and taxonomical research and food processing and quality control. Specific applications include: oligonucleotide and synthetic polymer analysis; protein identification and quantification; peptide de novo sequencing; determination of post-translational modifications of proteins; interaction proteomics and protein function analysis; drug discovery and development; and fast body fluid and tissue peptide or protein biomarker detection. MALDI mass spectrometry allows users to classify and identify microorganisms quickly and reliably with minimal sample preparation efforts and life cycle costs. Our MALDI Biotyper solution, which serves the clinical microbiology market, enables identification, taxonomical classification or dereplication of microorganisms like bacteria, yeasts and fungi.

        ESI-TOF mass spectrometers utilize an electrospray ionization process to analyze liquid samples. This ionization process, which does not dissociate the molecules, allows for rapid data acquisition and analysis of large biological molecules. ESI-TOF mass spectrometers are particularly useful for: identification, protein analysis and functional complex analysis in proteomics and protein function; molecular identification in metabolomics, natural product and drug metabolite analysis; combinatorial chemistry high throughput screening; and fast liquid chromatography mass spectrometry, or liquid chromatography mass spectrometry (LC-MS), in drug discovery and development.

        FTMS systems utilize high-field superconducting magnets to offer the highest resolution, selectivity, and mass accuracy currently achievable in mass spectrometry. Our systems based on this technology often eliminate the need for time-consuming separation techniques in complex mixture analyses. In

addition, our systems can fragment molecular ions to perform exact mass analysis on all fragments to determine molecular structure. FTMS systems are particularly useful for: the study of structure and function of biomolecules, including proteins, DNA and natural products; complex mixture analysis including body fluids or combinatorial libraries; high-throughput proteomics and metabolomics; and top-down proteomics of intact proteins without the need for enzymatic digestion of the proteins prior to analysis. We offer next-generation hybrid FTMS systems that combine a traditional external quadrupole mass selector and hexapole collision cell with a high-performance FTMS for further ion dissociation, top-down proteomics tools and ultra-high resolution detection.

        ITMS systems collect all ions simultaneously, which improves sensitivity relative to previous quadrupole mass spectrometers. Ion trap mass spectrometers are particularly useful for sequencing and identification based on peptide structural analysis, quantitative liquid chromatography mass spectrometry, identification of combinatorial libraries and generally enhancing the speed and efficiency of the drug discovery and development process.

        GC-MS systems combine the features of gas chromatography and mass spectrometry to identify different substances within a test sample. The two components, used together, allow for a finer degree of substance identification than either system when used separately. The result is a quantitative analysis of the components and the mass spectrum of each component. Our GC-MS systems are available in triple quadrupole configurations and can be configured with a variety of options to suit a range of applications. Our GC-MS systems have applications in food and product safety, forensics, clinical and toxicology testing and environmental, pharmaceutical and chemical analysis.

        LC-MS systems combine the separation features of liquid chromatography with the molecular identification features of mass spectrometry to separate, identify and quantify different substances within a test sample. As a complementary technique to GC-MS, which analyzes volatile compounds, LC-MS can be used to analyze a wide range of non-volatile compounds in complex samples. Our LC-MS systems are available in a wide range of configurations to suit a user's specific needs. Although primarily used for life science applications, our LC-MS systems also have applications in food and product safety, forensics and clinical and toxicology testing, as well as environmental, pharmaceutical and chemical analysis.

        FT-IR spectrometers utilize the mid- and far-infrared regions of the electromagnetic spectrum. Our FT-IR systems are commonly used for various quality control and materials research applications.

        NIR spectrometers utilize the near-infrared region of the electromagnetic spectrum. Our NIR instruments are primarily used for quality and process control applications in the pharmaceutical, food and agriculture and chemical industries. The pharmaceutical industry is the leading user of NIR instruments, and applications include quality control, research and development and process analytical technology. The food and agricultural industry is the second largest user of NIR instrumentation, with an increasing demand for food, forage and beverage quality control.

        Raman spectroscopy provides information on molecular structure. The mechanism of Raman scattering is different from that of infrared absorption, in that Raman and IR spectra provide complementary information. Raman is useful for the identification of both organic and inorganic compounds and functional groups. It is a nondestructive technique, and can be used for the analysis of both liquids and solids. Raman is well suited for use in the polymer and pharmaceutical industries, and has applications in the metals, electronics and semiconductors industries. The technique also has applications in life sciences, forensics and artwork authentication.

        XRD systems investigate polycrystalline samples or thin films with single wavelength X-rays. The atoms in the polycrystalline sample scatter the X-rays to create a unique diffraction pattern recorded by a detector. Computer software processes the pattern and produces a variety of information, including stress, texture, qualitative and quantitative phase composition, crystallite size, percent crystallinity and layer thickness, composition, defects and density of thin films and semiconductor material. Our XRD systems contribute to a reduction in the development cycles for new products in the catalyst, polymer, electronic, optical material and semiconductor industries. Customers also use our XRD systems academic and government research facilities, as well as a variety of other fields, including forensics, art and archaeology.

        XRF systems determine the elemental composition of a material and provide a full qualitative and quantitative analysis. Our XRF systems direct X-rays at a sample, and the atoms in the sample absorb the X-ray energy. The elements in the sample then emit X-rays that are characteristic for each element. The system collects the X-rays, and the software analyzes the resulting data to determine the elements that are present. Our XRF products provide automated solutions on a turn-key basis for industrial users that require automated, controlled production processes that reduce product and process cost, increase output and improve product quality. Our XRF products cover substantially all of the periodic table and can analyze solid, powder or liquid samples.

        SC-XRD systems determine the three-dimensional structures of molecules in a chemical, mineral, or biological substance being analyzed. SC-XRD systems have the capability to determine structure in both small chemical molecules and larger biomolecules. SC-XRD systems direct an X-ray beam at a solid, single crystal sample. The atoms in the crystal sample scatter the X-rays to create a precise diffraction pattern recorded by an electronic detector. Software then reconstructs a model of the structure and provides the unique arrangement of the atoms in the sample. This information on the exact arrangement of atoms in the sample is a critical part of molecular analysis and can provide insight into a variety of areas, including how a protein functions or interacts with a second molecule. Our SC-XRD systems are designed for use in the life sciences industry, academic research and a variety of other applications.

        µCT is X-ray imaging in 3D, by the same method used in hospital CT scans, but on a small scale with massively increased resolution. 3D microscopy allows users to image the internal structure of objects non-destructively on a very fine scale. Bruker µCT is available in a range of easy-to-use desktop instruments, which generate 3D images of the sample's morphology and internal microstructure with resolution down to the sub-micron level. Our µCT systems are used for numerous applications in materials research and in the life sciences industry.

        EDS systems analyze the chemical composition of materials under investigation in electron microscopes by utilizing the fact that atoms of different chemical elements, when exposed to the high energy electron beam generated by the microscope, irradiate X-rays of different characteristic energy. The evaluation of the energy spectrum collected by our spectrometer allows the determination of the qualitative and quantitative chemical sample composition at the current beam position. EDS systems allow for simultaneous analysis of all elements in the periodic table, beginning with atomic number 4 (beryllium). Our EDS systems are used for a range of applications, including nanotechnology and

advanced materials research, as well as materials analysis and quality control. Customers for EDS systems include industrial customers, academia and government research facilities.

        EBSD systems are used to perform quantitative microstructure analysis of crystalline samples in electron microscopes. The microscope's electron beam strikes the tilted sample and diffracted electrons form a pattern on a fluorescent screen. This pattern is characteristic of the crystal structure and orientation of the sample region from which it was generated. It provides the absolute crystal orientation with sub-micron resolution. EBSD can be used to characterize materials with regard to crystal orientation, texture, stress, strain and grain size. EBSD also allows the identification of crystalline phases and their distribution, and is applied to many industries such as metals processing, aerospace, automotive, microelectronics and earth sciences.

        S-OES instruments are used for analyzing metals. S-OES covers a broad range of applications for metals analysis from pure metals trace analysis to high alloyed grades, and allow for analysis of a complete range of relevant elements simultaneously. S-OES instruments pass an electric spark onto a sample, which burns the surface of the sample and causes atoms to jump to a higher orbit. Our detectors quantify the light emitted by these atoms and help our customers to determine the elemental composition of the material. This technique is widely used in production control laboratories of foundries and steel mills.

        CS/ONH carrier gas systems incorporate a furnace and infrared or thermal conductivity detection to analyze inorganic materials for the determination of carbon, sulfur, nitrogen, oxygen and hydrogen. Combustion and inert gas fusion analyzers are used for applications in metal production and processing, chemicals, ceramics and cement, coal processing, oil refining and semiconductors.

        AFM systems provide atomic or near-atomic resolution of material surface topography using a nano-scale probe that is brought into light contact with the sample being investigated. In addition to presenting a surface image, AFM can also provide quantitative nano-scale measurements of feature sizes, material properties, electrical information, chemical properties and other sample characteristics. Our AFM systems are used for applications in academic and governmental materials and biological research and semiconductor, data storage hard drive, LED, battery, solar cells, polymers, and pharmaceutical product development and manufacturing.

        FM products use fluorescence microscopy to determine the structure and composition of life science samples. Our products include two-photon microscopes, multipoint scanning confocal microscopes, laser illumination sources, photoactivation, photostimulation and photoablation accessories and synchronization and analysis software. Two-photon microscopes allow imaging deep into tissues and cells and are used widely in neuroscience. Multipoint scanning confocal systems allow live cell imaging with rapid acquisition of images for structural and composition analysis. We also offer super-resolution and single-molecule localization microscopy products which can break the optical diffraction limit by an order of magnitude.

        SOM systems provide atomic or near-atomic two dimensional and three dimensional surface resolution using white light interferometry, confocal optical and stylus profilometry methods. SOM profilers range from low-cost manual tools for single measurements to advanced, highly automated systems for production line quality assurance and quality control applications where the combination of throughput, repeatability and reproducibility is essential. SOM profilers support a range of applications in research, product development, tribology, quality control and failure analysis related to materials and machining in the automotive, orthopedic, ophthalmic, high brightness LED, semiconductor, data storage, optics and other markets.

        TMT systems provide a platform for all types of common mechanical, friction, durability, scratch and indentation tests for a wide spectrum of materials.

The sales cycle of our low temperature superconducting materials is typically four to twelve months, with cycles of certain high-end materials exceeding one year. Sales of our high-end NMR and superconducting devices typically take more than one year and certain large, complex contracts can take more than two years to complete.

        We have well-equipped applications and demonstration facilities and qualified application personnel who assist customers and provide product demonstrations in specific application areas. We maintain our primary demonstration facilities at our production facilities, as well as in other key market locations.

Seasonal Nature of Business

        Historically we have higher levels of revenue in the fourth quarter and lower levels of revenues in the first quarter of the year, which we believe is influenced by our customers' budgeting cycles.

Major Customers

        The Company has a broad and diversified customer base and we do not depend on any single customer. No single customer accounted for more than 10% of revenue in any of the last three fiscal years or more than 10% of accounts receivable as of December 31, 2017 or 2016.

Competition

        Our existing products and solutions and any products and solutions that we develop in the future may compete in multiple, highly competitive markets. In addition, there has been a trend towards consolidation in our industries and many of our competitors have substantially greater financial, technical and marketing resources than we do. Our competitors may succeed in developing and offering products that could render our products or those of our strategic partners obsolete or noncompetitive. Our competitors may also have cost and price advantages based upon the value of their currencies compared with the U.S. Dollar or Euro. In addition, many of these competitors have significantly more

experience in the life sciences, chemical and materials markets. Our ability to compete successfully will depend on our ability to develop proprietary products that reach our target markets in a timely manner and are technologically superior to and/or less expensive, or more cost effective, than products marketed by our competitors. Current competitors or other companies may possess or develop technologies and products that are more effective than ours. Our technologies and products may be rendered obsolete or uneconomical by technological advances or by entirely different approaches developed by one or more of our competitors.

        We also compete with companies that provide analytical or automation tools based on technologies other than those we offer. These technologies may prove to be more successful in meeting demands in the markets that our products and solutions are intended to serve. In addition, other companies may choose to enter our fields in the future. We believe that the principal competitive factors in our markets are technology-based applications expertise, product specifications, functionality, reliability, marketing expertise, distribution capability, proprietary patent portfolios and cost effectiveness.

We conduct research primarily to enhance system performance and improve the reliability of existing products, and to develop revolutionary new products and solutions. We expensed $162.7 million (9.2% of revenue), $149.0 million (9.2% of revenue) and $145.7 million (9.0% of revenue) in 2017, 2016 and 2015, respectively, for research and development purposes. Our research and development efforts are conducted for the relevant products within each of the operating segments, as well as in collaboration with others on areas such as microfluidics, automation and workflow management software. We have been the recipient of government grants from Germany and the United States for various projects related to early-stage research and development. We have generally retained, at a minimum, non-exclusive rights to any items or enhancements we develop under these grants. The German government requires that we use and market technology developed under grants in order to retain our rights to the technology. We have also accepted some sponsored research contracts from private sources.

BSI Segment

BEST maintains technical competencies in the production and development of low and high temperature superconducting materials and devices.

Intellectual Property

        Our intellectual property consists of patents, copyrights, trade secrets, know-how, and trademarks. Protection of our intellectual property is a strategic priority for our businesses because of the length of time and expense associated with bringing new products through the development process and to the marketplace. We have a substantial patent portfolio, and we intend to file additional patent applications as appropriate. We believe our owned and licensed patent portfolio provides us with a competitive advantage. This portfolio permits us to maintain access to a number of key technologies. We license our owned patent rights where appropriate. We intend to enforce our patent rights against infringers, if necessary. The patent positions of life sciences tools companies involve complex legal and factual questions. As a result, we cannot predict the enforceability of our patents with certainty. In addition, we are aware of the existence from time to time of patents in certain countries, which, if valid, could impair our ability to manufacture and sell products in these countries.

        We also rely upon trade secrets, know-how, trademarks, copyright protection and licensing to develop and maintain our competitive position. We generally require the execution of confidentiality agreements by our employees, consultants, and other scientific advisors. These agreements provide that all confidential information made known during the course of a relationship with us will be held in

14

Table of Contents

confidence and used only for our benefit. In addition, these agreements provide that we own all inventions generated during the course of the relationship.

Government Contracts

        We are a party to various government contracts. Under some of these government contracts, the government may receive license or similar rights to intellectual property developed under the contract. However, under government contracts we enter we generally receive at least non-exclusive rights to any items or technologies we develop. Although we transact business with various government agencies, we believe that no government contract is of such magnitude that a renegotiation of profits or termination of the contract or subcontracts at the election of the government would have a material adverse effect on our financial results.

Government Regulation

        We are required to comply with federal, state, and local environmental protection regulations. We do not expect this compliance to have a significant impact on our capital spending, earnings or competitive position.

        Prior to introducing a product in the United States, our Bruker AXS subsidiary provides notice to the U.S. Food and Drug Administration, or FDA, in the form of a Radiation Safety Initial Product Abbreviated Report, which provides identification information and operating characteristics of the product. If the FDA finds that the report is complete, it provides approval in the form of what is known as an accession number. Bruker AXS may not market a product until it has received an accession number. In addition, Bruker AXS submits an annual report to the FDA that includes the radiation safety history of all products it sells in the United States. Bruker AXS is required to report to the FDA incidents of accidental exposure to radiation arising from the manufacture, testing, or use of any of its products. Bruker AXS also reports installations of its products to state government regulatory agencies responsible for the regulation of radiation emitting devices. For sales in Germany, Bruker AXS registers each system with the local authorities. In some countries where Bruker AXS sells systems, Bruker AXS uses the license we obtained from the federal authorities in Germany to assist it in obtaining a license from the country in which the sale occurs. In addition, as indicated above, we are subject to various other foreign and domestic environmental, health and safety laws and regulations in connection with our operations. Apart from these areas, we are subject to the laws and regulations generally applicable to businesses in the jurisdictions in which we operate.

        Our Bruker AXS subsidiary possesses low-level radiation materials licenses from the U.S. Nuclear Regulatory Commission in agreement with the State of Wisconsin for its facility in Madison, Wisconsin; from the local radiation safety authority, Gewerbeaufsichtsamt Karlsruhe, for its facility in Karlsruhe, Germany; and from the local radiation safety authority, Kanagawa Prefecture, for its facility in Yokohama, Japan, as well as from various other countries in which it sells its products. Our Bruker Daltonics subsidiary possesses low-level radiation licenses for facilities in Billerica, Massachusetts and Leipzig, Germany. The U.S. Nuclear Regulatory Commission also has regulations concerning the exposure of our employees to radiation.

        Certain of our clinical products are subject to regulation in the United States by the FDA and by similar regulatory bodies in other countries where such products are sold. For example, our MALDI Biotyper CA system is subject to regulation by the FDA and our IVD-CE Certified MALDI BioTyper system is subject to regulation in the European Union under the provisions of Directive 98/79/EC. These, and similar local regulations elsewhere in the world, govern a wide variety of product-related activities, from quality management, design and development to labeling, manufacturing, promotion, sales and distribution. As such, we continually invest in our manufacturing infrastructure to gain and maintain certifications necessary for the relevant level of regulatory clearance.

Working Capital Requirements

        There were no credit terms extended to customers that would have a material adverse effect on our working capital.

        We recognize revenue from system sales when persuasive evidence of an arrangement exists, the price is fixed or determinable, title and risk of loss has been transferred to the customer, and collectability of the resulting receivable is reasonably assured. Title and risk of loss generally transfers upon shipment, or for certain systems, based upon customer acceptance for a system that has been delivered to the customer and installed at a customer facility. For systems that include customer-specific acceptance criteria, we are required to assess when we can demonstrate the acceptance criteria have been met, which generally is upon successful factory acceptance testing or customer acceptance and evidence of installation. Systems that have been shipped to customers, but not yet accepted by the customer, are included as finished goods in-transit. Finished goods in-transit was $41.4 million and $37.5 million at December 31, 2017 and 2016, respectively. We also have well-equipped applications and demonstration facilities and qualified application personnel who assist customers and provide product demonstrations in specific application areas. In total, we held $54.5 million and $34.8 million of demonstration inventory at December 31, 2017 and 2016, respectively.

Backlog

        Our backlog consists of firm orders under non-cancellable purchase orders received from customers. Total system backlog at December 31, 2017 and 2016 was approximately $1,010 million and $932 million, respectively. We anticipate that approximately 78% of the backlog as of December 31, 2017 will be filled in 2018. We experience variable and fluctuating revenues in the first three quarters of the year, while our fourth quarter revenues have historically been stronger than the rest of the year. As a result, backlog on any particular date can be indicative of our short-term revenue performance, but is not necessarily a reliable indicator of long-term revenue performance.

Employees

        As of December 31, 2017 and 2016, we had approximately 6,200 and 6,000 full-time employees worldwide, respectively. Of these employees, approximately 1,085 and 1,075 were located in the United States as of December 31, 2017 and 2016, respectively. Our employees in the United States are not unionized or affiliated with any labor organizations. Employees based outside the United States are primarily located in Europe, with worker's councils or labor unions primarily in Germany and France. Several of our international subsidiaries are parties to contracts with labor unions and workers' councils. We believe that we have good relationships with our employees and the workers' councils.

        As of December 31, 2017, we had approximately 3,035 employees in production and distribution, 1,482 employees in selling and marketing and 1,000 employees in research and development, with general and administrative employees representing the remainder. As of December 31, 2016, we had approximately 2,975 employees in production and distribution, 1,500 employees in selling and marketing and 940 employees in research and development, with general and administrative employees representing the remainder.

Available Information

        We are subject to the informational requirements of the Securities Exchange Act of 1934 ("Exchange Act"). Therefore, we file periodic reports, proxy statements and other information with the Securities and Exchange Commission ("SEC"). Such reports, proxy statements and other information may be read and copied by visiting the Public Reference Room of the SEC at 100 F Street N.E., Washington, D.C. 20549. You may obtain information on the operation of the Public Reference Room by calling the SEC at 1-800-SEC-0330. In addition, the SEC maintains an Internet site (http://www.sec.gov) that contains reports, proxy and information statements and other information regarding issuers that file electronically.

        Our website is located at www.bruker.com. We make available free of charge through this website our annual reports on Form 10-K, quarterly reports on Form 10-Q, current reports on Form 8-K, and amendments to those reports filed with or furnished to the SEC pursuant to Section 13(a) or 15(d) of the Exchange Act, as soon as reasonably practicable after they are electronically filed with or furnished to the SEC. The contents of our website are not incorporated into this report.

ITEM 1A    RISK FACTORS

        The following risk factors should be considered in conjunction with the other information included in this Annual Report on Form 10-K. This report may include forward-looking statements that involve risks and uncertainties. In addition to those risk factors discussed elsewhere in this report, we identify the following risk factors, which could affect our actual results and cause actual results to differ materially from those in the forward-looking statements.

We may lose money when we exchange foreign currency received from international sales into U.S. Dollars.

        A significant portion of our business is conducted in currencies other than the U.S. Dollar, which is our reporting currency. As a result, currency fluctuations among the U.S. Dollar and the currencies in which we do business have caused, and will continue to cause, foreign currency translation gains and losses. In addition, currency fluctuations could cause the price of our products to be more or less competitive than our principal competitors' products. Currency fluctuations will increase or decrease our cost structure relative to those of our competitors, which could lessen the demand for our products and affect our competitive position. From time to time we enter into certain hedging transactions and/or option and foreign currency exchange contracts which are intended to offset some of the market risk associated with our sales denominated in foreign currencies. We cannot predict the effectiveness of these transactions or their impact upon our future operating results, and from time to time they may negatively affect our quarterly earnings.

Our reported financial results may be adversely affected by fluctuations in currency exchange rates.

        In addition to the foreign currency exposure associated with differences between where our products are manufactured and sold by us and our competitors, our exposure to currency exchange rate fluctuations results from the currency translation exposure associated with the preparation of our consolidated financial statements, as well as from the exposure associated with transactions of our subsidiaries that are denominated in a currency other than the respective subsidiary's functional currency. While our financial results are reported in U.S. Dollars, the financial statements of many of our subsidiaries outside the U.S. are prepared using the local currency as the functional currency. During consolidation, these results are translated into U.S. Dollars by applying appropriate exchange rates. As a result, fluctuations in the exchange rate of the U.S. Dollar relative to the local currencies in which our foreign subsidiaries report could cause significant fluctuations in our reported results. Moreover, as exchange rates vary, revenue and other operating results may differ materially from our expectations. The favorable effects of changes in currency exchange rates increased our 2017 revenues

17

---

Table of Contents

by approximately $19.6 million, or 1.2%, while unfavorable foreign currency effects decreased our 2016 revenues by approximately $8.3 million, or 0.5%, respectively. Adjustments resulting from financial statement translations are included as a separate component of shareholders' equity. In the year ended December 31, 2017, we recorded net gains from currency translation adjustments of $97.1 million. In the year ended December 31, 2016, we recorded net losses from currency translation adjustments of $27.6 million.

        Additionally, to the extent monetary assets and liabilities, including cash and debt, are held in a different currency than the reporting subsidiary's functional currency, fluctuations in currency exchange rates may have a significant impact on our reported financial results, and may lead to increased earnings volatility. We may record significant gains or losses related to both the translation of assets and liabilities held by our subsidiaries into local currencies and the remeasurement of inter-company receivables and loan balances.

Unfavorable economic or political conditions in the countries in which we operate may have an adverse impact on our business results or financial condition.

        Our businesses and results of operations are affected by international, national and regional economic and political conditions. Our businesses or financial results may be adversely impacted by unfavorable changes in economic or political conditions in the countries and markets in which we operate, including, among others, adverse changes in interest rates or tax rates, volatility in financial and commodity markets, contraction in the availability of credit in the marketplace, and changes in capital spending patterns.

        Our revenue from U.S. operations represented approximately 25% and 27% of total consolidated revenue for fiscal 2017 and 2016, respectively. Our revenue from operations in Europe represented approximately 38% and 36% of total consolidated revenue for the corresponding periods. Our revenue from operations in the Asia Pacific region represented approximately 29% and 28% of total consolidated revenue for the corresponding periods. Economic factors that could adversely influence demand for the Company's products include uncertainty about global economic conditions leading to reduced levels of investment, changes in government spending levels and/or priorities, the size and availability of government budgets, customers' and suppliers' access to credit and other macroeconomic factors affecting government, academic or industrial spending behavior. Slower economic growth or a deterioration in economic conditions could result in a decrease in government funding for scientific research, a delay in orders from current or potential customers or a reduction in purchases of our products.

        We cannot predict how changes in economic conditions or political instability will affect our customers and suppliers or how any negative impact on our customers and suppliers might adversely impact our business results or financial condition.

The effect of comprehensive U.S. tax reform legislation is uncertain.

        On December 22, 2017, the President of the United States signed the Tax Cuts and Jobs Act, or the 2017 Tax Act, which enacted a wide range of changes to the U.S. income tax system, many of which differ significantly from the provisions of the previous U.S. tax law. The 2017 Tax Act, among other things, permanently reduces the U.S. corporate income tax rate to 21% beginning in 2018 and provides for more general changes to the taxation of corporations, including changes to the deductibility of interest expense, the adoption of a modified territorial tax system, assessing a repatriation tax or "toll-charge" on undistributed earnings and profits of U.S.-owned foreign corporations and broadening the corporate tax base through the elimination or reduction of deductions, exclusions and credits. We have not yet completed our assessment of the tax effects associated with the enactment of the 2017 Tax Act; however, reasonable estimates have been made of the effects of the 2017 Tax Act on the

18

---

Table of Contents

Company's existing deferred tax balances and the one-time transition tax on undistributed earnings and profits of our foreign subsidiaries. Changes in the tax rates and laws are accounted for in the period of enactment and these estimates are reflected in our financial statements for the period ended December 31, 2017.

        The actual results of the implementation of the 2017 Tax Act may materially differ from our current estimate due to, among other things, further guidance that may be issued by U.S. tax authorities or regulatory bodies, including the SEC and the Financial Accounting Standards Board (FASB) to interpret the 2017 Tax Act. We will continue to analyze the 2017 Tax Act and any additional guidance that may be issued and finalize the full effects of applying the new legislation in future periods. Any revisions to our current estimates could materially affect our results of operations, cash flow and financial position.

We derive a significant portion of our revenue from international sales and are subject to the risks of doing business in foreign countries.

        International sales account, and are expected to continue to account, for a significant portion of our total revenues. Our revenue from non-U.S. operations represented approximately 75% and 73% of our total consolidated revenue for fiscal 2017 and 2016, respectively. Our international operations are, and will continue to be, subject to a variety of risks associated with conducting business internationally, many of which are beyond our control. These risks, which may adversely affect our ability to achieve and maintain profitability and our ability to sell our products internationally, include:

•

changes in foreign currency translation rates;



•

changes in regulatory requirements;



•

legislation and regulation, including tariffs, relating to the import or export of high technology products;



•

the imposition of government controls;



•

political and economic instability, including international hostilities, acts of terrorism and governmental restrictions, inflation, trade relationships and military and political alliances;



•

costs and risks of deploying systems in foreign countries;



•

compliance with export laws and controls and trade embargoes in multiple jurisdictions;



•

limited intellectual property rights;



•

the burden of complying with a wide variety of complex foreign laws and treaties, including unfavorable labor regulations, specifically those applicable to our European operations; and



•

compliance with U.S. and local laws affecting the activities of U.S. companies abroad, including the United States Foreign Corrupt Practices Act, or FCPA, and local anti-bribery laws.

        We must also comply with the recently enacted European Union General Data Protection Regulation (GDPR). All European Union member states must comply with GDPR by May 2018. The goal of the regulation is to increase individual rights and protections for personal data located in or originating from the European Union. GDPR is extraterritorial in that it applies to all business within the European Union and any business is located outside of the European Union that processes personal data of individuals located within the European Union. There are significant fines associated with non-compliance.

        While the impact of these factors is difficult to predict, any one or more of these factors could adversely affect our operations in the future.

If we are not able to successfully integrate the businesses we acquire through mergers, acquisitions or strategic alliances, we may not be able to realize all of the cost savings and other benefits that we expect to result from the transactions and our financial results may be different than expected.

        Our strategy includes expanding our technology base and product offerings through selected mergers, acquisitions and strategic alliances. For example, from 2015 to December 31, 2017, we have acquired 13 businesses to expand our technologies and product offerings.

        Successful integration of the businesses we acquire involves a number of risks, including, among others, risks related to:

•

coordinating or consolidating geographically separate organizations and integrating personnel with different business backgrounds and corporate cultures;



•

integrating previously autonomous departments in sales and marketing, distribution, accounting and administrative functions, and information and management systems;



•

diversion of resources and management time;



•

disruption of our ongoing business;



•

potential impairment of relationships with customers as a result of changes in management or otherwise arising out of such transactions; and



•

retention of key employees of the acquired businesses within the first one to two years after the acquisition, including the risk that they may compete with us subsequently.

        We may have difficulty developing, manufacturing and marketing the products of a newly acquired company or business in a way that enhances the performance of our combined businesses or product lines. As a result, we may not realize the value from expected synergies. Acquisitions have resulted, and may in the future result, in unexpected significant costs and expenses. In the future, we may be required to record charges to earnings during the period if we determine there is an impairment of goodwill or intangible assets, up to the full amount of the value of the assets.

It may be difficult for us to implement our strategies for improving margins, profitability and cash flow.

        We are pursuing a number of strategies to improve our financial performance, including implementing various productivity improvement initiatives at both BSI and BEST in an effort to streamline our operations. These initiatives include the outsourcing of manufacturing activities, consolidating, transferring or ceasing operations at certain facilities; applying lean manufacturing and six sigma concepts to our operations, implementing ERP and other information technology systems and applying a shared service approach to various functions.

        We may not be able to successfully implement these strategies, and these efforts may not result in the expected improvement in our margins, profitability or cash flow. Anticipated benefits to our operating and financial performance might be reduced or delayed as a result of difficulties in implementing these initiatives, which may include complications in the transfer of assets and production knowledge, loss of key employees and/or customers, the disruption of ongoing business and possible inconsistencies in standards, controls and procedures. Implementation costs also might exceed our expectations and further cost reduction measures might become necessary, resulting in additional future charges. Our ability to successfully implement these strategies and achieve our objectives will also depend on our ability to identify, attract and retain management and other personnel with the skills and experience needed to effectively manage the process and drive our operating performance improvement during and after implementation of our improvement initiatives.

20

Table of Contents

        These improvement strategies may also have unintended consequences, such as attrition beyond our intended reduction in workforce, reduced employee morale and loss of customer relationships. We also may undertake additional restructuring activities in the future. Because of these and other factors, we cannot predict whether we will realize the purpose and anticipated benefits of our restructuring and related measures, and if we do not, our business and results of operations may be adversely affected.

Goodwill, intangible assets and other long-lived assets are subject to impairment.

        We have recorded goodwill, intangible assets and other long-lived assets that must be periodically evaluated for potential impairment. We assess the realizability of the reported goodwill, intangible assets and other long-lived assets annually, as well as whenever events or changes in circumstances indicate that the assets may be impaired. These events or circumstances generally include operating losses or a significant decline in the earnings associated with the reporting unit these assets are reported within. A decline in our stock price and market capitalization may also cause us to consider whether goodwill, intangible assets and other long-lived assets may require an impairment assessment. Our ability to realize the value of these assets will depend on the future cash flows of the reporting unit in addition to how well we integrate the businesses we acquire. We have recorded impairment losses of $1.1 million, $0.8 million and $4.6 million for the years ended December 31, 2017, 2016 and 2015, respectively.

If our products fail to achieve and sustain sufficient market acceptance across their broad intended range of applications, we will not generate expected revenue.

        Our business strategy depends on our ability to successfully commercialize a broad range of products based on our technology platforms, including magnetic resonance technology, pre-clinical imaging technology, mass spectrometry technology, X-ray technology, atomic force microscopy technology, stylus and optical metrology technology, fluorescence microscopy technology, infrared technology and superconducting magnet technologies for use in a variety of life science, chemistry and materials analysis applications. Some of our products have only recently been commercially launched and have achieved only limited sales to date. The commercial success of our products depends on obtaining and expanding market acceptance by a diverse array of industrial, academic, clinical, pharmaceutical, biotechnology, applied, medical research and governmental customers around the world. We may fail to achieve or sustain substantial market acceptance for our products across the full range of our intended applications or in one or more of our principal intended applications. Any such failure could decrease our sales and revenue. To succeed, we must convince substantial numbers of potential customers to invest in new systems or replace their existing techniques with techniques employing our systems. Limited funding available for capital acquisitions by our customers, as well as our customers' own internal purchasing approval policies, could hinder market acceptance of our products. Our intended customers may be reluctant to make the substantial capital investment generally needed to acquire our products or to incur the training and other costs involved with replacing their existing systems with our products. We also may not be able to convince our intended customers that our systems are an attractive and cost-effective alternative to other technologies and systems for the acquisition, analysis and management of molecular, cellular and microscopic information. Additionally, if ethical and other concerns surrounding the use of genetic information, gene therapy or genetically modified organisms become widespread, we may have less demand for our products. Because of these and other factors, our products may fail to gain or sustain market acceptance.

Our products compete in markets that are subject to rapid technological change, and one or more of the technologies underlying our products could be made obsolete by new technology.

        The market for discovery and analysis tools is characterized by rapid technological change and frequent new product introductions. Rapidly changing technology could make some or our entire

21

Table of Contents

product lines obsolete unless we are able to continually improve our existing products and develop new products. Because substantially all of our products are based on our technology platforms, including magnetic resonance technology, mass spectrometry technology, X-ray technology, atomic force microscopy technology, fluorescence microscopy technology, stylus and optical metrology technology and infrared technology, we are particularly vulnerable to any technological advances that would make these techniques obsolete as the basis for analytical systems in any of our markets. To meet the evolving needs of our customers, we must rapidly and continually enhance our current and planned products and services and develop and introduce new products and services. In addition, our product lines are based on complex technologies that are subject to rapid change as new technologies are developed and introduced in the marketplace. We may have difficulty in keeping abreast of the rapid changes affecting each of the different markets we serve or intend to serve. If we fail to develop and introduce products in a timely manner in response to changing technology, market demands or the requirements of our customers, our product sales may decline, and we could experience significant losses. Currently in our backlog, we have orders totaling $112.0 million for ultra-high field magnets. If we are unable to reach the technical feasibility for these magnets, we will be unable to fulfill customer orders where alternate arrangements have not been provided for in customer contracts. Additional risks include extraordinary warranty expenses, rework and potential inventory write-offs.

Our business could be harmed if our collaborations fail to advance our product development.

        Demand for our products will depend, in part, upon the extent to which our collaborations with pharmaceutical, biotechnology and proteomics companies are successful in developing, or helping us to develop, new products and new applications for our existing products. In addition, we collaborate with academic institutions and government research laboratories on product development. We have limited or no control over the resources that any collaborator may devote to our products. Any of our present or future collaborators may not perform their obligations as expected. If we fail to enter into or maintain appropriate collaboration agreements, or if any of these events occur, we may not be able to develop some of our new products, which could materially impede our ability to generate revenue or profits.

We face substantial competition.

        We face substantial competition in our industries and we expect that competition in all of our markets will increase further. Currently, our principal competition comes from established companies providing products using existing technologies that perform many of the same functions for which we market our products. A number of our competitors have expanded their market share in recent years through business combinations. Other companies also may choose to enter our fields in the future. Our competitors may develop or market products that are more effective or commercially attractive than our current or future products or that may render our products obsolete. Competition has in the past subjected, and is likely in the future to subject, our products to pricing pressure. Many of our competitors have more experience in the market and substantially greater financial, operational, marketing and technical resources than we do, which could give them a competitive advantage in areas such as research and development, production, marketing and distribution. Our ability to compete successfully will depend, in part, on our ability to develop proprietary products that reach the market in a timely manner and are technologically superior to, less expensive than, or more cost-effective than, other currently marketed products.

If we lose our strategic partners, our marketing and sales efforts could be impaired.

        A substantial portion of our sales of selected products consists of sales to third parties who incorporate our products into their systems. These third parties are responsible for the marketing and sales of their systems. We have little or no control over their marketing and sales activities or how they

22

---

Table of Contents

use their resources. Our present or future strategic partners may or may not purchase sufficient quantities of products from us or perform appropriate marketing and sales activities. In addition, if we are unable to maintain our relationships with strategic partners, our businesses may suffer. Failures by our present or future strategic partners, or our inability to maintain or enter into new arrangements with strategic partners for product distribution, could materially impede the growth of our businesses and our ability to generate sufficient revenue and profits.

We face risks related to sales through distributors and other third parties that we do not control, which could harm our business.

        We sell some products through third party agents, including distributors and value-added resellers. This exposes us to various risks, including competitive pressure, concentration of sales volumes, credit risks, and compliance risks. We may rely on one or a few key distributors for a product or market, and the loss of these distributors could reduce our revenue and net earnings. Distributors may also face financial difficulties, including bankruptcy, which could harm our collection of accounts receivables. Risks related to our use of distributors may reduce sales, increase expenses, and weaken our competitive position. Moreover, violations of the FCPA or similar anti-bribery laws by distributors or other third party agents could materially and adversely impact our business and results of operations.

Dependence on contract manufacturing may adversely affect our ability to bring products to market and damage our reputation.

        As part of our efforts to streamline our operations and reduce our operating costs, we outsource aspects of our manufacturing processes and continue to evaluate additional outsourcing. If our contract manufacturers fail to perform their obligations in a timely manner or at satisfactory quality levels, our ability to bring products to market and our reputation could suffer. For example, during a market upturn, our contract manufacturers may be unable to meet our demand requirements, which may preclude us from fulfilling our customers' orders on a timely basis. The ability of these manufacturers to perform is largely outside our control. Additionally, changing or replacing our contract manufacturers could cause disruptions or delays. Problems with outsourced manufacturing could result in lower revenues and unexecuted efficiencies, and adversely affect our financial condition and results of operations.

If investment in life and material science research spending declines, our ability to generate revenue may suffer.

        We are dependent, both directly and indirectly, upon general investment in life science research, particularly in the research and development budgets of the pharmaceutical and biotechnology industries, and in material science research as well as upon the financial condition and funding priorities of various governments and government agencies. Since our inception, both we and our academic collaborators and customers have benefited from various governmental contracts and research grants. Whether we or our academic collaborators will continue to be able to attract these grants depends not only on the quality of our products, but also on general spending patterns of public institutions.

Any reduction in the capital resources or government funding of our customers could reduce our sales and impede our ability to generate revenue.

        A significant portion of our sales are capital purchases by our customers. The spending policies of our customers could have a significant effect on the demand for our products. These policies are based on a wide variety of factors, including the resources available to make purchases, the spending priorities among various types of equipment, policies regarding spending during recessionary periods and changes in the political climate. Any changes in capital spending or changes in the capital budgets of our

23

---

Table of Contents

customers could significantly reduce demand for our products. The capital resources of our life science and other corporate customers may be limited by the availability of equity or debt financing. Any significant decline in research and development expenditures by our life science and material science customers could significantly decrease our sales. In addition, a substantial portion of our sales are to non-profit and government entities, which are dependent on government support for scientific research. Any decline in this support could decrease the ability of these customers to purchase our products.

Disruptions at any of our manufacturing facilities could adversely affect our business.

        We have manufacturing facilities located in the United States, Europe and Israel. Many of our products are developed and manufactured at single locations, with limited alternate facilities. If we experience any significant disruption of those facilities for any reason, such as strikes or other labor unrest, power interruptions, fire, earthquakes, or other events beyond our control, we may be unable to manufacture the relevant products at previous levels or at all. A reduction or interruption in manufacturing could harm our customer relationships, impede our ability to generate revenues from our backlog or obtain new orders and could have a material adverse effect on our business, results of operations, financial condition and cash flows.

If employees were to engage in a strike or other work stoppage or interruption, our business, results of operations, financial condition and liquidity could be materially adversely affected.

        Some of our employees are represented by workers' councils and labor unions in certain jurisdictions, primarily in Germany and France. Although we believe that our relations with our employees are satisfactory, if disputes with these employees arise, or if our workers engage in a strike or other work stoppage or interruption, we could experience a significant disruption of, or inefficiencies in, our operations or incur higher labor costs, which could have a material adverse effect on our business, results of operations, financial condition and liquidity.

Our operations are dependent upon a limited number of suppliers and contract manufacturers.

        We currently purchase components used in our products from a limited number of outside suppliers. Our reliance on a limited number of suppliers could result in time delays associated with redesigning a product due to an inability to obtain an adequate supply of required components and reduced control over pricing, quality and timely delivery. Any of these factors could adversely affect our revenues and profitability. In particular, our X-ray microanalysis business, which manufactures and sells accessories for electron microscopes, is partially dependent on cooperation from larger manufacturers of electron microscopes. Additionally, our elemental analysis business purchases certain optical detectors from a single supplier, PerkinElmer, Inc., the sole supplier of these detector components. Bruker CALID purchases detectors and power supplies from sole or limited source suppliers and its focal plane array detectors from a single supplier, Lockheed Martin Corporation. Similarly, Bruker BioSpin obtains various components from sole or limited source suppliers and BEST obtains various raw materials and uses key production equipment from sole or limited source suppliers or contract manufacturers. There are limited, if any, available alternatives to these suppliers. The existence of shortages of these components or the failure of delivery with regard to these components could have a material adverse effect upon our revenues and margins. In addition, price increases from these suppliers or contract manufacturers could have a material adverse effect upon our gross margins.

        Because of the scarcity of some components, we may be unable to obtain an adequate supply of components, or we may be required to pay higher prices or to purchase components of lesser quality. Any delay or interruption in the supply of these or other components could impair our ability to manufacture and deliver our products, harm our reputation and cause a reduction in our revenues. In addition, any increase in the cost of the components that we use in our products could make our products less competitive and decrease our gross profits. We may not be able to obtain sufficient

24

Table of Contents

quantities of required components on the same or substantially the same terms. Additionally, consolidation among our suppliers could result in other sole source suppliers for us in the future.

Supply shortages and increasing prices of raw materials could adversely affect the gross profit of the Bruker BioSpin Group and of our Bruker Energy & Supercon Technologies business.

        The last few years have seen periodic supply shortages and sharp increases in the prices for various raw materials, in part due to high demand from developing countries. Bruker BioSpin and BEST rely on some of these materials for the production of their products. In particular, for its superconducting magnet production, both for the horizontal and vertical magnet series, Bruker BioSpin relies on the availability of copper, steel and the metallic raw materials for traditional low-temperature superconducting wires. Similarly, BEST relies on the availability of niobium titanium for its production of low-temperature superconducting materials and devices. Higher prices for these commodities will increase the production cost of superconducting wires and superconducting magnets and may adversely affect gross profits.

        The prices of copper and certain other raw materials used for superconductors have increased significantly over the last decade. Since copper is a main constituent of low temperature superconductors, this may affect the price of superconducting wire. This type of increase would have an immediate effect on the production costs of superconducting magnets and may negatively affect the profit margins for those products. In addition, an increase in raw material cost affects the production cost of the superconducting wire produced by BEST and of superconducting wire used by Bruker BioSpin.

        Bruker BioSpin and its customers also rely on liquid helium to operate its superconducting magnets. Helium is controlled by the Federal Helium Reserve and is subject to price changes. Shortages of liquid helium associated with federal price controls could have an adverse impact on producing and operating BioSpin's superconducting magnets and may also negatively impact the profit margins for those products.

Regulations related to "conflict minerals" may cause us to incur additional expenses and could limit the supply and increase the cost of certain metals used in manufacturing our products.

        Regulations require disclosures by public companies of specified minerals, known as conflict minerals, that are necessary to the functionality or production of products manufactured or contracted to be manufactured. This requires the performance of due diligence to determine whether or not such minerals originate from the Democratic Republic of Congo or an adjoining country. These regulations could affect sourcing at competitive prices and availability in sufficient quantities of certain minerals used in the manufacture of our products, including tantalum, tin, gold and tungsten. The number of suppliers who provide conflict-free minerals may be limited. In addition, there may be material costs associated with complying with the disclosure requirements, such as costs related to determining the source of certain minerals used in our products, as well as costs of possible changes to products, processes or sources of supply as a consequence of such verification activities. As our supply chain is complex and we use contract manufacturers for some of our products, we may not be able to sufficiently verify the origins of the relevant minerals used in our products through the due diligence procedures that we implement, which may harm our reputation. In addition, we may encounter challenges to satisfy those customers who require that all of the components of our products be certified as conflict-free, which could place us at a competitive disadvantage if we are unable to do so.

If we fail to maintain an effective system of internal controls, we may not be able to accurately report our financial results, which could lead to a loss of investor confidence in our financial statements and have an adverse effect on our stock price.

        Effective internal controls are necessary for us to provide reliable and accurate financial statements and to effectively prevent fraud. We devote significant resources and time to comply with the internal control over financial reporting requirements of the Sarbanes Oxley Act of 2002 and continue to enhance our controls. However, we cannot be certain that we will be able to prevent future significant deficiencies or material weaknesses. In the year ended December 31, 2017, we remediated the previously disclosed material weakness in our internal controls over the accounting for income taxes. Inadequate internal controls could cause investors to lose confidence in our reported financial information, which could have a negative effect on investor confidence in our financial statements, the trading price of our stock and our access to capital.

Our manufacture and sale of products could lead to product liability claims for which we could have substantial liability.

        The manufacture and sale of our products expose us to product liability claims if any of our products cause injury or are found otherwise unsuitable during manufacturing, marketing, sale or customer use. In particular, if one of our CBRNE detection products malfunctions, this could lead to civilian or military casualties in a time of unrest, exposing us to increased potential for high-profile liability. If our CBRNE detection products malfunction by generating a false-positive to a potential threat, we could be exposed to liabilities associated with actions taken that otherwise would not have been required. Additionally, the nuclear magnetic resonance, research magnetic resonance imaging, Fourier transform mass spectrometry and certain electron paramagnetic resonance magnets of Bruker BioSpin utilize high magnet fields and cryogenics to operate at approximately 4 Kelvin, the temperature of liquid helium. There is an inherent risk of potential product liability due to the existence of these high magnetic fields, associated stray fields outside the magnet, and the handling of the cryogens associated with superconducting magnets. In addition, our MALDI Biotyper product has an IVD-CE mark and is used for the identification of microorganisms. Misidentification or a false-negative of certain bacteria, yeasts or fungi could lead to inappropriate treatment for patients, and could expose us to product liability claims.

        A successful product liability claim brought against us in excess of, or outside the coverage of, our insurance coverage could have a material adverse effect on our business, financial condition and results of operations. We may not be able to maintain product liability insurance on acceptable terms, if at all, and insurance may not provide adequate coverage against potential liabilities.

Responding to claims relating to improper handling, storage or disposal of hazardous chemicals and radioactive and biological materials which we use could be time consuming and costly.

        We use controlled hazardous and radioactive materials in our business and generate wastes that are regulated as hazardous wastes under U.S. federal, and Massachusetts, California, New Jersey, Washington and Wisconsin state, environmental and atomic energy regulatory laws and under equivalent provisions of law in those and other jurisdictions in which our research and manufacturing facilities are located. Our use of these substances and materials is subject to stringent, and periodically changing, regulation that can impose costly compliance obligations on us and have the potential to adversely affect our manufacturing activities. The risk of accidental contamination or injury from these materials cannot be completely eliminated. If an accident with these substances occurs, we could be held liable for any damages that result, in addition to incurring clean-up costs and liabilities, which can be substantial. Additionally, an accident could damage our research and manufacturing facilities resulting in delays and increased costs.

26

Table of Contents

We are subject to environmental laws and regulations which may impose significant compliance or other costs on us.

        Our manufacturing, product development and research and development operations and processes involve the controlled use of certain hazardous materials. In addition, we own and/or lease a number of facilities, some of which have been in operation for many decades, where we or others may have used substances or generated and disposed of wastes which are considered hazardous or may be considered hazardous in the future. We also have acquired various companies which historically may have used certain hazardous materials and which may have owned and/or leased facilities at which hazardous materials have been used. For all of these reasons, we are subject to federal, state, foreign, and local laws and regulations governing the use, manufacture, storage, transportation, handling, treatment, remediation, and disposal of hazardous materials and certain waste products. We have potential liability under these laws and regulations with respect to the remediation of past contamination in certain of the facilities we now own or lease. Additionally, in the future our facilities and the disposal sites owned by others to which we send or sent waste, may be identified as contaminated and require remediation. Accordingly, we may become subject to additional compliance costs or environmental liabilities which may be significant and could materially harm our results of operations or financial condition.

In addition to the risks applicable to our life science and materials analysis products, our CBRNE detection products are subject to a number of additional risks, including lengthy product development and contract negotiation periods and certain risks inherent in long-term government contracts.

        Our CBRNE detection products are subject to many of the same risks associated with our life science products, including vulnerability to rapid technological change, dependence on mass spectrometry and other technologies and substantial competition. In addition, our CBRNE detection products and certain FT-IR products are generally sold to government agencies under long-term contracts. These contracts generally involve lengthy pre-contract negotiations and product development. We may be required to devote substantial working capital and other resources prior to obtaining product orders. As a result, we may incur substantial costs before we recognize revenue from these products. Moreover, in return for larger, longer-term contracts, our customers for these products often demand more stringent acceptance criteria. These criteria may also cause delays in our ability to recognize revenue from sales of these products. Furthermore, we may not be able to accurately predict in advance our costs to fulfill our obligations under these long-term contracts. If we fail to accurately predict our costs, due to inflation or other factors, we could incur significant losses. Also, the presence or absence of such contracts may cause substantial variation in our results of operations between fiscal periods and, as a result, our results of operations for any given fiscal period may not be predictive of our results for subsequent fiscal periods. The resulting uncertainty may have an adverse impact on our stock price.

We are subject to existing and potential additional regulation and government inquiry, which can impose burdens on our operations and narrow the markets for our products.

        We are subject, both directly and indirectly, to the adverse impact of existing and potential future government regulation of our operations and markets. For example, exportation of our products, particularly our CBRNE detection products, is subject to strict regulatory control in a number of jurisdictions. The failure to satisfy export control criteria or obtain necessary clearances could delay or prevent shipment of products, which could adversely affect our revenues and profitability.

        In addition, as a result of our international operations, we are subject to compliance with various laws and regulations, including the FCPA and local anti-bribery laws in the jurisdictions in which we do business, which generally prohibit companies and their intermediaries or agents from engaging in bribery or making improper payments to foreign officials or their agents. The FCPA also requires proper record keeping and characterization of such payments in our reports filed with the SEC.

Despite maintaining policies and procedures that require our employees to comply with these laws and our standards of ethical conduct, we cannot ensure that these policies and procedures will always protect us from intentional, reckless or negligent acts committed by our employees or agents. For example, in 2014 we resolved an investigation by the SEC into possible violations of the FCPA arising from past conduct of our subsidiaries operating in China. In connection with the resolution, we consented to the entry of an administrative cease and desist order by the SEC concerning violations of the books and records and internal controls provisions of the FCPA and paid an aggregate amount of approximately $2.4 million, consisting of $1.7 million in disgorgement, $0.3 million in prejudgment interest, and a $0.4 million penalty. We also incurred legal and professional fees associated with the investigation and settlement of approximately $25.1 million. Additionally, in 2017 we resolved an investigation of the Korea Fair Trade Commission ("KFTC") into improper bidding by Bruker Korea Co., Ltd. ("Bruker Korea") and several other companies in connection with bids for sales of X-ray systems in 2010 and 2012. In connection with these matters, various Korean governmental entities imposed suspensions on Bruker Korea, with overlapping suspension periods ranging from three to six months. During the periods of these suspensions, which expired in 2017, Bruker Korea was prohibited from bidding for or conducting sales to Korean governmental agencies.

        On October 19, 2017, the Company received a notice of investigation and subpoena to produce documents from the Division of Enforcement of the SEC. The subpoena seeks information related to an employee terminated as part of a restructuring and certain matters involving the Company's policies and accounting practices related to revenue recognition and restructuring activities, as well as related financial reporting, disclosure and compliance matters, since January 1, 2013. The subpoena also seeks information concerning, among other things, the Company's previously identified material weakness in internal controls over the accounting for income taxes, related financial reporting matters and certain payments for non-employee travel expenses. The Company is producing documents in response to the subpoena and intends to continue to cooperate fully with the SEC's investigation. At this time, the Company is unable to predict the duration, scope or outcome of this investigation.

        Moreover, the life sciences industry, which is the market for our principal products, has historically been heavily regulated. There are, for example, laws in several jurisdictions restricting research in genetic engineering, which can operate to narrow our markets. Given the evolving nature of this industry, legislative bodies or regulatory authorities may adopt additional regulation that adversely affects our market opportunities. Our business is also directly affected by a wide variety of government regulations applicable to business enterprises generally and to companies operating in the life sciences industry in particular.

        Our clinical products are subject to regulation by the FDA. These regulations govern a wide variety of product related activities, from quality management, design and development to labeling, manufacturing, promotion, sales and distribution. If we or any of our suppliers or distributors fail to comply with FDA and other applicable regulatory requirements, or are perceived to potentially have failed to comply, we may face, among other things, warning letters; adverse publicity affecting both us and our customers; investigations or notices of non-compliance, fines, injunctions, and civil penalties; import or export restrictions; partial suspensions or total shutdown of production facilities or the imposition of operating restrictions; increased difficulty in obtaining required FDA clearances or approvals or foreign equivalents; seizures or recalls of our products or those of our customers; or the inability to sell such products. Any such FDA actions could disrupt our business and operations, lead to significant remedial costs and have a material adverse impact on our financial position and results of operations.

        We have been, are, and expect to be in the future, subject to inquiries from the government agencies that enforce these regulations, including the U.S. Department of State, the U.S. Department of Commerce, the U.S. Food and Drug Administration, the U.S. Internal Revenue Service, the U.S. Department of Homeland Security, the U.S. Department of Justice, the Securities and Exchange

28

Table of Contents

Commission, the Federal Trade Commission, the U.S. Customs and Border Protection and the U.S. Department of Defense, among others, as well as from state or foreign governments and their departments and agencies. As a result, from time to time, the attention of our management and other resources may be diverted to attend to these inquiries. In addition, failure to comply with these regulations or obtain or maintain necessary permits and licenses could result in a variety of fines or other censures or an interruption in our business operations which may have a negative impact on our ability to generate revenues and could adversely affect our financial condition and results of operations.

Our success depends on our ability to operate without infringing or misappropriating the proprietary rights of others.

        Our commercial success depends on avoiding the infringement of other parties' patents and proprietary rights as well as avoiding the breach of any licenses relating to our technologies and products. Given that there may be patents of which we are unaware, particularly in the United States where patent applications are confidential, avoidance of patent infringement may be difficult. Various third parties hold patents which may relate to our technology, and we may be found in the future to infringe these or other patents or proprietary rights of third parties, either with products we are currently marketing or developing or with new products which we may develop in the future. If a third party holding rights under a patent successfully asserts an infringement claim with respect to any of our current or future products, we may be prevented from manufacturing or marketing our infringing product in the country or countries covered by the patent we infringe, unless we can obtain a license from the patent holder. We may not be able to obtain a license on commercially reasonable terms, if at all, especially if the patent holder is a competitor. In addition, even if we can obtain the license, it may be non-exclusive, which will permit others to practice the same technology licensed to us. We also may be required to pay substantial damages to the patent holder in the event of an infringement. Under some circumstances in the United States these damages could include damages equal to triple the actual damages the patent holder incurs. If we have supplied infringing products to third parties for marketing by them or licensed third parties to manufacture, use or market infringing products, we may be obligated to indemnify these third parties for any damages they may be required to pay to the patent holder and for any losses the third parties may sustain themselves as the result of lost sales or license payments they are required to make to the patent holder. Any successful infringement action brought against us may also adversely affect marketing of the infringing product in other markets not covered by the infringement action, as well as our marketing of other products based on similar technology. Furthermore, we will suffer adverse consequences from a successful infringement action against us even if the action is subsequently reversed on appeal, nullified through another action or resolved by settlement with the patent holder. The damages or other remedies awarded, if any, may be significant. As a result, any successful infringement action against us may harm our business.

If we are unable to effectively protect our intellectual property, third parties may use our technology, which would impair our ability to compete in our markets.

        Our continued success will depend in significant part on our ability to obtain and maintain meaningful patent protection for our products throughout the world. We rely on patents to protect a significant part of our intellectual property and to enhance our competitive position. However, our presently pending or future patent applications may not issue as patents, and any patent previously issued to us may be challenged, invalidated, held unenforceable or circumvented. Furthermore, the claims in patents which have been issued, or which may be issued to us in the future, may not be sufficiently broad to prevent third parties from producing competing products similar to our products. In addition, the laws of various foreign countries in which we compete may not protect our intellectual property to the same extent as do the laws of the United States. Failure to obtain adequate patent protection for our proprietary technology could materially impair our ability to be commercially competitive.

29

Table of Contents

        In addition to patent protection, we also rely on the protection of trade secrets, know-how and confidential and proprietary information. To maintain the confidentiality of trade secrets and proprietary information, we generally seek to enter into confidentiality agreements with our employees, consultants and strategic partners upon the commencement of a relationship with us. However, we may not obtain these agreements in all circumstances. In the event of unauthorized use or disclosure of this information, these agreements, even if obtained, may not provide meaningful protection for our trade secrets or other confidential information. In addition, adequate remedies may not exist in the event of unauthorized use or disclosure of this information. The loss or exposure of our trade secrets and other proprietary information would impair our competitive advantages and could have a material adverse effect on our operating results, financial condition and future growth prospects. Furthermore, others may have, or may in the future independently develop, substantially similar or superior know-how and technology.

We may be involved in lawsuits to protect or enforce our patents that are brought by us which could be expensive and time consuming and, if determined adversely, could adversely affect our patent position.

        In order to protect or enforce our patent rights, we may initiate patent litigation against third parties, and we may be similarly sued by others. We may also become subject to interference proceedings conducted in the patent and trademark offices of various countries to determine the priority of inventions. The defense and prosecution, if necessary, of intellectual property suits, interference proceedings and related legal and administrative proceedings is costly and diverts our technical and management personnel from their normal responsibilities. We may not prevail in any of these suits. An adverse determination of any litigation or defense proceedings could put our patents at risk of being invalidated or interpreted narrowly and could put our patent applications at risk of not issuing.

        Furthermore, because of the substantial amount of discovery required in connection with intellectual property litigation, there is a risk that some of our confidential information could be compromised by disclosure during this type of litigation. In addition, during the course of this kind of litigation, there could be public announcements of the results of hearings, motions or other interim proceedings or developments in the litigation. If securities analysts or investors perceive these results to be negative, it could have a substantial negative effect on the trading price of our common stock.

We rely on information technology to support our operations and reporting environments. A security failure of that technology could impact our ability to operate our businesses effectively, adversely affect our financial results, damage our reputation and expose us to potential liability or litigation.

        We use information systems to carry out our operations and maintain our business records. Some systems are internally managed and some are maintained by third-party service providers. We and our service providers employ what we believe are adequate security measures. Our ability to conduct business could be materially and adversely affected if these systems or resources are compromised, damaged or fail. This could be a result of a cyber-incident, natural disaster, hardware or software corruption, failure or error, telecommunications system failure, service provider error or failure, intentional or unintentional personnel actions or other disruption.

        In the ordinary course of business, we collect and store sensitive data, including intellectual property, other proprietary information and personally identifiable information. If this data is compromised, destroyed or inappropriately disclosed, it could have a material adverse effect, including damage to our reputation, loss of customers, significant expenses to address and resolve the issues, or litigation or other proceedings by affected individuals, business partners or regulatory authorities.

Our debt may adversely affect our cash flow and may restrict our investment opportunities or limit our activities.

        As of December 31, 2017, we had outstanding an aggregate principal amount of debt totaling approximately $415.6 million, including $220.0 million of senior unsecured notes, $195.0 million of long-term borrowings under our revolving loan facility and $1.3 million of other debt, offset by unamortized debt issuance costs for the senior unsecured notes of $0.7 million. We also had the ability to borrow an additional $303.9 million available under our existing credit facility. Most of our outstanding debt is in the United States and there are substantial cash requirements in the United States to service debt interest obligations, fund operations, capital expenditures and our declared dividends and finance potential acquisitions or share repurchases. Our ability to satisfy our debt obligations and meet our other liquidity needs depends on our future operating performance and on economic, financial, competitive and other factors beyond our control. Our business may not generate sufficient cash flow to meet our debt obligations or provide sufficient funds for our other objectives. If we are unable to service our debt or obtain additional financing, we may be forced to delay strategic acquisitions, capital expenditures or research and development expenditures or suspend our dividend payments and share repurchases. We may not be able to obtain additional financing on terms acceptable to us or at all. Furthermore, a majority of our cash, cash equivalents and short-term investments is generated from foreign operations, with $405.8 million, or 92.4% held by foreign subsidiaries as of December 31, 2017. Our financial condition and results of operations could be adversely impacted if we are unable to maintain a sufficient level of cash flow in the United States to address our funding requirements through cash from operations and timely repatriation of cash from overseas or other sources obtained at an acceptable cost.

        Additionally, the agreements governing our debt require that we maintain certain financial ratios related to maximum leverage and minimum interest coverage and contain negative covenants, including among others, restrictions on liens, indebtedness of the Company and its subsidiaries, asset sales, dividends and transactions with affiliates. Our ability to comply with these financial restrictions and covenants is dependent on our future performance, which is subject to prevailing economic conditions and other factors, including factors that are beyond our control such as foreign currency translation rates and interest rates. Our failure to comply with any of these restrictions or covenants may result in an event of default under the applicable debt instrument, which could permit acceleration of the debt under the facility and require us to prepay the debt before its scheduled due date.

Changes in our effective income tax rate could adversely affect our results of operations.

        We are subject to income taxes in both the United States and various foreign jurisdictions and our domestic and international tax liabilities are largely dependent upon the distribution of income among these different jurisdictions. Various factors may have favorable or unfavorable effects on our effective income tax rate. These factors include interpretations of existing tax laws, the accounting for stock options and other share-based compensation, changes in tax laws and rates, including the recently enacted Tax Cuts and Jobs Act, future levels of research and development spending, changes in accounting standards, changes in the mix of earnings in the various tax jurisdictions in which we operate, the outcome of examinations by the U.S. Internal Revenue Service and other tax authorities, the accuracy of our estimates for unrecognized tax benefits and realization of deferred tax assets and changes in overall levels of pre-tax earnings.

Various international tax risks could adversely affect our earnings and cash flows.

        We are subject to international tax risks. We could be subject to double taxation on income related to operations in certain countries that do not have tax treaties with the country of the trading partner. In addition, we may have a higher effective income tax rate than that of other companies in our industry if losses incurred by one operating company are not available to offset the income of an

31

operating company located in another country. Also, distributions of earnings and other payments received from our subsidiaries may be subject to withholding taxes imposed by the countries where they are operating or are incorporated. If these foreign countries do not have income tax treaties with the United States or the countries where our subsidiaries are incorporated, we could be subject to high rates of withholding taxes on these distributions and payments. Additionally, the amount of the credit that we may claim against our U.S. federal income tax for foreign income taxes paid or accrued is subject to many limitations which may significantly restrict our ability to claim a credit for all of the foreign taxes we pay.

        We currently have reserves established for potential tax liabilities. If these reserves are challenged, and we are unable to successfully defend our tax positions, a negative impact to our cash flows could result.

The unpredictability and fluctuation of our quarterly results may adversely affect the trading price of our common stock.

        Our revenues and results of operations have in the past and will in the future vary from quarter to quarter due to a number of factors, many of which are outside our control and any of which may cause our stock price to fluctuate. The primary factors that may affect us include the following:

•

the timing of sales of our products and services;



•

the timing of recognizing revenue and deferred revenue under U.S. GAAP;



•

changes in our pricing policies or the pricing policies of our competitors;



•

increases in sales and marketing, product development or administration expenses;



•

the mix of services provided by us and third-party contractors;



•

our ability to attain and maintain quality levels for our products;



•

costs related to acquisitions of technology or businesses; and



•

the effectiveness of transactions entered into to hedge the risks associated with foreign currency and interest rate fluctuations.

        We can experience quarter-to-quarter fluctuations in our operating results as a result of various factors, some of which are outside our control, such as:

•

the timing of governmental stimulus programs and academic research budgets;



•

the time it takes between the date customer orders and deposits are received, systems are shipped and accepted by our customers and full payment is received;



•

the time it takes to satisfy local customs requirements and other export/import requirements;



•

the time it takes for customers to construct or prepare their facilities for our products; and



•

the time required to obtain governmental licenses.

        These factors have in the past affected the amount and timing of revenue recognized on sales of our products and receipt of related payments and will continue to do so in the future. Accordingly, our operating results in any particular quarter may not necessarily be an indication of any future quarter's operating performance.

        Historically we have higher levels of revenue in the fourth quarter of the year compared to the first, second and third quarters, which we believe is primarily the result of our customers' budgeting cycles. Quarter-to-quarter comparisons of our results of operations should not be relied upon as an indication of our future performance. It is likely that in some future quarters, our results of operations

32

may be below the expectations of public market analysts and investors. In this event, the price of our common stock may fall.

Existing stockholders have significant influence over us.

        As of March 12, 2018, Laukien family members, including our Chairman, President and Chief Executive Officer Frank Laukien and Director Joerg Laukien, owned, in the aggregate, approximately 35.7% of our outstanding common stock. As a result, these stockholders will be able to exercise substantial influence over all matters requiring stockholder approval, including the election of directors and approval of significant corporate transactions. This could have the effect of delaying or preventing a change in control of our company and will make some transactions difficult to accomplish without the support of these stockholders.

Other companies may have difficulty acquiring us, even if doing so would benefit our stockholders, due to provisions under our corporate charter and bylaws, as well as Delaware law.

        Provisions in our certificate of incorporation, as amended, and our bylaws, as well as Delaware law could make it more difficult for other companies to acquire us, even if doing so would benefit our stockholders. Our certificate of incorporation, as amended, and bylaws contain the following provisions, among others, which may inhibit an acquisition of our company by a third party:

•

a staggered Board of Directors, where stockholders elect only a minority of the board each year;



•

advance notification procedures for matters to be brought before stockholder meetings;



•

a limitation on who may call stockholder meetings; and



•

the ability of our Board of Directors to issue up to 5,000,000 shares of preferred stock without a stockholder vote.

ITEM 3    LEGAL PROCEEDINGS

        We are involved in lawsuits, claims, and proceedings, including, but not limited to, patent and commercial matters, which arise in the ordinary course of business. There are no such matters pending that we currently believe are reasonably possible of having a material impact on our business or to our consolidated financial statements.

        In addition, from time to time, the Company is the subject of investigations by national, state and local government agencies in the United States and other countries in which it operates, involving, among other things, regulatory, financial reporting, marketing and other business practices. These governmental investigations may result in the commencement of civil and criminal proceedings, fines, penalties and administrative remedies and may have a material adverse effect on our financial position, results of operations and/or business.

        On October 19, 2017, we received a notice of investigation and subpoena to produce documents from the Division of Enforcement of the SEC. The subpoena seeks information related to an employee terminated as part of a restructuring and certain matters involving the Company's policies and accounting practices related to revenue recognition and restructuring activities, as well as related financial reporting, disclosure and compliance matters, since January 1, 2013. The subpoena also seeks information concerning, among other things, the Company's previously identified material weakness in internal controls over the accounting for income taxes, related financial reporting matters and certain payments for non-employee travel expenses. The Company is producing documents in response to the subpoena and intends to continue to cooperate fully with the SEC's investigation. At this time, we are unable to predict the duration, scope or outcome of this investigation.

ITEM 7    MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

        The following Management's Discussion and Analysis of Financial Condition and Results of Operations, or MD&A, describes the principal factors affecting the results of our operations, financial condition and changes in financial condition, as well as our critical accounting policies and estimates. Our MD&A is organized as follows:

•

Overview.  This section provides a brief discussion of our reportable segments' results of operations, significant recent developments in our businesses, and challenges and risks that may impact our businesses in the future.



•

Results of Operations.  This section provides our analysis of the significant line items on our consolidated statements of income and comprehensive income for the year ended December 31, 2017 compared to the year ended December 31, 2016 and for the year ended December 31, 2016 compared to the year ended December 31, 2015.



•

Liquidity and Capital Resources.  This section provides an analysis of our liquidity and cash flow and a discussion of our outstanding debt and commitments.



•

Critical Accounting Policies and Estimates.  This section discusses the accounting estimates that are considered important to our financial condition and results of operations and require us to exercise subjective or complex judgments in their application. All of our significant accounting policies are summarized in Note 2 to our consolidated financial statements in Item 8 of this Annual Report on Form 10-K.



•

Recent Accounting Pronouncements.  This section provides a summary of recent accounting pronouncements and discusses their potential impact on our consolidated financial statements.



•

Transactions with Related Parties.  This section summarizes transactions with related parties.

        Statements contained in Management's Discussion and Analysis of Financial Condition and Results of Operations, which express that we "believe," "anticipate," "plan," "expect," "seek," "estimate," or "should," as well as other statements which are not historical fact, are forward-looking statements within the meaning of the Private Securities Litigation Reform Act of 1995. Actual events or results may differ materially from those set forth in forward-looking statements. Certain factors that might cause such a difference are discussed in "Risk Factors" and "Management's Discussion and Analysis of Financial Condition and Results of Operations" in this Annual Report on Form 10-K for the year ended December 31, 2017.

        Although our consolidated financial statements have been prepared in accordance with generally accepted accounting principles in the United States of America (GAAP), we believe describing revenue and expenses, excluding the effects of foreign currency, acquisitions and divestitures, as well as certain other charges, net, provides meaningful supplemental information regarding our performance. Specifically, management believes that free cash flow and organic revenue, both non-GAAP financial measures, as well as non-GAAP gross profit margin and non-GAAP operating margin, provide relevant and useful information which is widely used by equity analysts, investors and competitors in our industry, as well as by our management, in assessing both consolidated and business unit performance. We define the term organic revenue as GAAP revenue excluding the effect of foreign currency translation changes and the effect of acquisitions and divestitures. We define the term non-GAAP gross profit margin as GAAP gross profit margin with certain non-GAAP measures excluded and non-GAAP operating margin as GAAP operating margin with certain non-GAAP measures excluded. These non-GAAP measures exclude costs related to restructuring actions, acquisition and related integration expenses, amortization of acquired intangible assets and other costs that are infrequent or non-recurring in nature and we believe these are useful measures to evaluate our continuing business.

41

Table of Contents

We define free cash flow as net cash provided by operating activities less additions to property, plant, and equipment. We believe free cash flow is a useful measure to evaluate our business as it indicates the amount of cash generated after additions to property, plant, and equipment which is available for, among other things, investments in our business, acquisitions, share repurchases, dividends and repayment of debt.

        We use these non-GAAP financial measures to evaluate our period-over-period operating performance because our management believes they provide more comparable measures of our continuing business because they adjust for certain items that are not reflective of the underlying performance of our business. These measures may also be useful to investors in evaluating the underlying operating performance of our business. We regularly use these non-GAAP financial measures internally to understand, manage, and evaluate our business results and make operating decisions. We also measure our employees and compensate them, in part, based on such non-GAAP measures and use this information for our planning and forecasting activities. The presentation of these non-GAAP financial measures is not intended to be a substitute for, or superior to, the financial information prepared and presented in accordance with GAAP and may be different from non-GAAP financial measures used by other companies, and therefore, may not be comparable among companies.

OVERVIEW

        We are organized into four operating segments: the Bruker BioSpin Group, the Bruker CALID Group, the Bruker Nano Group and the Bruker Energy & Supercon Technologies (BEST) Segment.

        For the year ended December 31, 2017, our revenue increased by $154.6 million, or 9.6%, to $1,765.9 million, compared to $1,611.3 million for the year ended December 31, 2016. Included in revenue were an increase of approximately $77.2 million attributable to our recent acquisitions and an increase of approximately $19.6 million from the impact of foreign currency translation caused by the weakening of the U.S. Dollar versus the Euro and other currencies. Excluding the effects of foreign currency translation and our recent acquisitions, our organic revenue, a non-GAAP measure, increased by $57.8 million, or 3.6%.

        Our gross profit margin remained approximately consistent at 46.0% during the year ended December 31, 2017 as compared to 46.1% during the year ended December 31, 2016. The positive effect of higher sales resulting from improvements in European and Industrial end markets was offset primarily by unfavorable business and product mix caused higher revenues in our now larger BEST segment which has lower gross profit margins and unfavorable mix within the BioSpin Group.

        Our operating margin increased to 12.2% for the year ended December 31, 2017 from 11.0% during the year ended December 31, 2016 demonstrating operating leverage following Bruker's multi-year operational transformation while appropriately investing in our six strategic growth areas. The operating margin increased due primarily to positive operating leverage on higher sales, cost discipline and savings from restructuring initiatives. These factors more than offset dilution from recent acquisitions and foreign currency translations effects.

        The income tax provision in the years ended December 31, 2017 and 2016 was $117.5 million and $23.1 million, respectively, representing effective tax rates of 59.4% and 13.0%, respectively. The increase in our effective tax rate for the year ended December 31, 2017, compared to 2016, was primarily attributable to the impact of U.S. tax reform in 2017 offset by the 2016 release of our remaining valuation allowances and the recognition of previously unrecognized tax benefits due to the closure of tax audits in 2016. Our tax rate may change over time as the amount and mix of jurisdictional income changes.

        On December 22, 2017 (Enactment Date), the President of the United States signed tax reform legislation (2017 Tax Act), which enacted a wide range of changes to the U.S. corporate income tax

system, many of which differ significantly from the provisions of the previous U.S. tax law. We have not yet completed the assessment of the tax effects associated with the enactment of the 2017 Tax Act. However, a reasonable estimate has been made of the effects on the existing deferred tax balances and the one-time transition tax. Changes in the tax rates and laws are accounted for in the period of enactment. Therefore, during the fourth quarter of 2017, we recorded an incremental income tax provision of $68.9 million, which is primarily comprised of the following:

•

An estimated income tax provision of $55.0 million for the federal and state impacts of the one-time deemed repatriation of pre-2018 E&P. In accordance with the 2017 Tax Act, the federal portion of the toll charge liability may be paid over eight years. Such liability can be reduced by certain credits. Accordingly, we have recorded $30.6 million and $2.7 million in long-term income tax liabilities and accrued income taxes (current), respectively, as of December 31, 2017



•

An estimated net income tax benefit of $1.4 million, for the remeasurement of our deferred tax assets and liabilities at the newly enacted tax rate of 21%; and



•

As a result of the 2017 Tax Act and our expectations about distributing certain cash balances from its foreign subsidiaries to the United States, we also recorded estimated income tax provisions for estimated state income taxes and foreign withholding taxes of $12.5 million.

        The actual results of the implementation of the 2017 Tax Act may materially differ from our current estimate due to, among other things, further guidance that may be issued by U.S. tax authorities or regulatory bodies including the SEC and the FASB to interpret the 2017 Tax Act. We will continue to analyze the 2017 Tax Act and any additional guidance that may be issued and finalize the full effects of applying the new legislation in the measurement period.

        Earnings per share decreased from $0.95 to $0.49 per diluted share for the year ended December 31, 2017 when compared to the year ended December 31, 2016. The decrease was primarily due to the impact of U.S. tax reform which resulted in a significantly higher effective tax rate for the year ended December 31, 2017.

        Operating cash flow for the year ended December 31, 2017 was a source of cash of $154.4 million. For the year ended December 31, 2017, our free cash flow, a non-GAAP measure, was $110.7 million, calculated as follows:

        For the year ended December 31, 2017 our free cash flow was 18% higher than for the year ended December 31, 2016 primarily attributable to higher net earnings adjusted for non-cash items, lower inventory levels and timing of employee payments. These effects were partially offset by an increase in accounts receivables caused by proportionately higher sales late in the fourth quarter of 2017.

        In May 2017, our Board of Directors approved a share repurchase program (the "Repurchase Program") that authorized repurchases of up to $225.0 million of common stock over two years. A total of 5,318,063 shares were repurchased at an aggregate cost of $152.2 million in the twelve months ended December 31, 2017.

        On February 22, 2016, we announced the establishment of a dividend policy and the declaration by our Board of Directors of an initial quarterly cash dividend in the amount of $0.04 per share of our issued and outstanding common stock. Dividends amounting to $25.4 million and $25.8 million were

43

paid during the years ended December 31, 2017 and 2016, respectively. Future dividend payments, if any are subject to approval of our Board of Directors. We are targeting a cash dividend to our shareholders in the amount of $0.16 per share per annum, payable in equal quarterly installments.

        In the years ended December 31, 2017 and 2016, we completed various acquisitions that complemented our existing market offerings and added aftermarket and software capabilities to our existing microbiology business. The impact of the acquired companies on revenues, net income and total assets was not material.

        We can experience quarter-to-quarter fluctuations in our operating results as a result of various factors, some of which are outside of our control, such as:

•

the timing of governmental stimulus programs and academic research budgets;



•

the time it takes between the date customer orders and deposits are received, systems are shipped and accepted by our customers and full payment is received;



•

the time it takes to satisfy local customs requirements and other export/import requirements;



•

the time it takes for customers to construct or prepare their facilities for our products; and



•

the time required to obtain governmental licenses.

        These factors have in the past affected the amount and timing of revenue recognized on sales of our products and receipt of related payments and will continue to do so in the future. Accordingly, our operating results in any particular quarter may not necessarily be an indication of any future quarter's operating performance.

RESULTS OF OPERATIONS

Year Ended December 31, 2017 Compared to the Year Ended December 31, 2016

Consolidated Results

        The following table presents our results for the years ended December 31, 2017 and 2016 (dollars in millions, except per share data):

Revenue

        For the year ended December 31, 2017, our revenue increased by $154.6 million, or 9.6%, to $1,765.9 million, compared to $1,611.3 million for the year ended December 31, 2016. Included in revenue were an increase of approximately $77.2 million attributable to our recent acquisitions and an

increase of approximately $19.6 million from the impact of foreign currency translation caused by the weakening of the U.S. Dollar versus the Euro and other currencies. Excluding the effects of foreign currency translation and our recent acquisitions, our organic revenue, a non-GAAP measure, increased by $57.8 million, or 3.6%.

Gross Profit

        Our gross profit for the year ended December 31, 2017 was $813.0 million, resulting in a gross profit margin of 46.0%, compared to $742.5 million, resulting in a gross profit margin of 46.1%, for the year ended December 31, 2016. Included in gross profit were various charges for amortization of acquisition-related intangible assets and other acquisition-related costs and restructuring costs totaling $36.1 million and $31.9 million for the years ended December 31, 2017 and 2016, respectively. Excluding these charges, our non-GAAP gross profit margins was 48.1% in each of the years ended December 31, 2017 and 2016.

Selling, General and Administrative

        Our selling, general and administrative expenses for the year ended December 31, 2017 increased to $415.9 million, or 23.6% of revenue, from $390.5 million, or 24.2% of revenue, for the year ended December 31, 2016. The increase was primarily caused by the effect of recent acquisitions in our Bruker Nano Group and Bruker CALID Group. The decrease in selling, general and administrative expenses as a percentage of revenue was attributable to cost control discipline and savings associated with restructuring initiatives.

Research and Development

        Our research and development expenses for the year ended December 31, 2017 increased to $162.7 million, or 9.2% of revenue, from $149.0 million, or 9.2% of revenue, for the year ended December 31, 2016. The increase was primarily caused by the effect of recent acquisitions in our Bruker Nano Group and Bruker CALID Group.

Other Charges, Net

        Other charges, net was $19.7 million for the year ended December 31, 2017, of which $18.7 million related to the BSI Segment and $1.0 million related to the BEST Segment. The charges consisted primarily of $10.6 million of restructuring costs related to closing facilities and implementing outsourcing and other restructuring initiatives, $4.5 million related primarily to additional contingent consideration recognized for the acquisition of Jordan Valley Semiconductors, Ltd. ("Jordan Valley") based upon an increase in revenue levels of the acquired business which increased the amount of expected earn out payments, $4.2 million of costs associated with our global information technology (IT) transformation initiative and impairment charges of $0.2 million comprised of other long-lived assets related to the restructuring actions.

        Other charges, net was $25.8 million for the year ended December 31, 2016, of which $25.2 million related to the BSI Segment and $0.6 million related to the BEST Segment. The charges consisted primarily of $9.8 million of restructuring costs related to closing facilities and implementing outsourcing and other restructuring initiatives, $9.0 million related primarily to additional contingent consideration recognized for the Jordan Valley acquisition based upon an increase in revenue levels of the acquired business which increased the amount of expected earn out payments, $6.2 million of costs associated with our global IT transformation initiative and impairment charges of $0.8 million comprised of other long-lived assets related to the restructuring actions within the Bruker CALID and Bruker Nano Groups during the year.

        In 2018, we expect to incur $7.0 to $10.0 million of expense related to various outsourcing initiatives and other restructuring activities that were implemented in 2017 or will commence in 2018.

        At December 31, 2017 and 2016, we performed our annual goodwill and indefinite-lived intangible impairment evaluation and concluded the fair values of each of our reporting units were significantly greater than their carrying amounts, and therefore, no additional impairment is required.

        We will continue to monitor goodwill and long-lived intangible assets, as well as long-lived tangible assets, for possible future impairment.

Operating Income

        Operating income for the year ended December 31, 2017 was $214.7 million, resulting in an operating margin of 12.2%, compared to income from operations of $177.2 million, resulting in an operating margin of 11.0%, for the year ended December 31, 2016. The operating margin increased due primarily to positive operating leverage on higher revenues, cost discipline and savings from restructuring initiatives. These factors more than offset dilution from recent acquisitions and foreign currency translation effects. Included in operating income were various charges for amortization of acquisition-related intangible assets and other acquisition-related costs and restructuring costs totaling $61.4 million and $60.7 million for the years ended December 31, 2017 and 2016, respectively. Excluding these charges, our non-GAAP operating margins was 15.6% and 14.8% in the years ended December 31, 2017 and 2016, respectively.

Interest and Other Income (Expense), Net

        Interest and other income (expense), net during the year ended December 31, 2017 was ($16.9) million, compared to $0.4 million for the year ended December 31, 2016.

        During the year ended December 31, 2017, the major components within interest and other income (expense), net were net interest expense of $14.6 million and realized and unrealized losses on foreign currency denominated transactions of $5.5 million, partially offset by $2.1 million of proceeds from a cargo insurance settlement and a gain on acquisition of $0.6 million. The $0.6 million gain on acquisition related to the acquisition of MERLIN Diagnostika GmbH within the BSI Segment as the value of the assets purchased exceeded the consideration paid. During the year ended December 31, 2016, the major components within interest and other income (expense), net were a gain on acquisition of $9.2 million, realized and unrealized gains on foreign currency denominated transactions of $4.1 million, partially offset by net interest expense of $12.9 million. The $9.2 million gain on acquisition related to the acquisition of Oxford Instruments Superconducting Wire LLC ("OST") within the BEST Segment as the value of the assets purchased exceeded the consideration paid.

        We expect to incur approximately $13.5 million of interest expense in 2018.

Income Tax Provision

        The income tax provision in the years ended December 31, 2017 and 2016 was $117.5 million and $23.1 million, respectively, representing effective tax rates of 59.4% and 13.0%, respectively. The increase in our effective tax rate for the year ended December 31, 2017, compared to 2016, was primarily attributable impact of U.S. tax reform in 2017 which was offset by the 2016 release of our remaining valuation allowances and the recognition of previously unrecognized tax benefits due to the closure of tax audits in 2016. Our tax rate may change over time as the amount and mix of jurisdictional income changes.

        We expect our effective income tax rate to be approximately 25.0% for the year ended December 31, 2018.

        On December 22, 2017 (Enactment Date), the President of the United States signed tax reform legislation (2017 Tax Act), which enacted a wide range of changes to the U.S. corporate income tax system, many of which differ significantly from the provisions of the previous U.S. tax law. We have not yet completed the assessment of the tax effects associated with the enactment of the 2017 Tax Act. However, a reasonable estimate has been made of the effects on the existing deferred tax balances and the one-time transition tax. Changes in the tax rates and laws are accounted for in the period of enactment. Therefore, during the fourth quarter of 2017, we recorded an incremental income tax provision of $68.9 million, which is primarily comprised of the following:

•

An estimated income tax provision of $55.0 million for the federal and state impacts of the one-time deemed repatriation of pre-2018 E&P. In accordance with the 2017 Tax Act, the federal portion of the toll charge liability may be paid over eight years. Such liability can be reduced by certain credits. Accordingly, we have recorded $30.6 million and $2.7 million in long-term income tax liabilities and accrued income taxes (current), respectively, as of December 31, 2017



•

An estimated net income tax benefit of $1.4 million, for the remeasurement of our deferred tax assets and liabilities at the newly enacted tax rate of 21%; and



•

As a result of the 2017 Tax Act and our expectations about distributing certain cash balances from its foreign subsidiaries to the United States, we also recorded estimated income tax provisions for estimated state income taxes and foreign withholding taxes of $12.5 million.

        The actual results of the implementation of the 2017 Tax Act may materially differ from our current estimate due to, among other things, further guidance that may be issued by U.S. tax authorities or regulatory bodies including the SEC and the FASB to interpret the 2017 Tax Act. We will continue to analyze the 2017 Tax Act and any additional guidance that may be issued and finalize the full effects of applying the new legislation in the measurement period.

        The majority of the Company's earnings are derived in Germany and Switzerland. Accounting for the various federal and local taxing authorities, the statutory rates for 2017 were approximately 30.0% and 20.0% for Germany and Switzerland, respectively. The mix of earnings in those two jurisdictions resulted in a reduction of 7.8% from the U.S. statutory rate of 35.0% in 2017. The Company has not been party to any tax holiday agreements.

Net Income Attributable to Noncontrolling Interests

        Net income attributable to noncontrolling interests for the year ended December 31, 2017 was $1.7 million compared to $0.9 million for the year ended December 31, 2016. The net income attributable to noncontrolling interests represented the minority shareholders' proportionate share of the net income recorded by our majority-owned indirect subsidiaries.

Net Income Attributable to Bruker Corporation

        Our net income attributable to Bruker Corporation for the year ended December 31, 2017 was $78.6 million, or $0.49 per diluted share, compared to net income of $153.6 million, or $0.95 per diluted share, for 2016. The decrease for the year ended December 31, 2017 was primarily caused by the impact of U.S. tax reform as noted above.

Segment Results

Revenue

        The following table presents revenue, change in revenue, and revenue growth by reportable segment for the years ended December 31, 2017 and 2016 (dollars in millions):

BSI Segment Revenues

        For financial reporting purposes, we aggregate the Bruker BioSpin, Bruker CALID and Bruker Nano operating segments into the Bruker Scientific Instruments (BSI) reportable segment, which represented approximately 90% of the Company's revenues during the year ended December 31, 2017. This aggregation reflects these operating segments' similar economic characteristics, production processes, customer services provided, types and classes of customers, methods of distribution and regulatory environments. Our BEST Segment is our other reportable segment and represents the remainder of our revenues.

        BSI Segment revenue increased by $91.3 million, or 6.1%, to $1,583.9 million for the year ended December 31, 2017, compared to $1,492.6 million for the year ended December 31, 2016. Included in revenue was an increase of approximately $33.4 million related to our recent acquisitions and approximately $17.3 million from the impact of foreign currency translation caused by the weakening of the U.S. Dollar versus the Euro and other currencies. Excluding the effects of foreign currency translation and our recent acquisitions, organic revenue, a non-GAAP measure, increased by $40.6 million, or 2.7%.

        Bruker BioSpin Group revenue increased by $9.2 million to $571.9 million for the year ended December 31, 2017, compared to $562.7 million for the year ended December 31, 2016. The Bruker BioSpin Group revenue increased despite a challenging comparison as the year ended December 31, 2016 benefited from the sale of the first shielded ultra-high field one gigahertz NMR system and higher levels of high field NMR systems. The increase in revenue was primarily attributable to the service and aftermarket business of the Bruker BioSpin Group and foreign currency translations.

        Bruker CALID Group revenue increased by $23.6 million to $499.0 million for the year ended December 31, 2017 compared to $475.4 million for the year ended December 31, 2016. The Bruker CALID Group increase was primarily the result of improved academic end markets, particularly for mass spectrometry products and within Europe, and infrared and Raman technologies used in applied and industrial end markets, and the contributions of acquisitions and foreign currency translation effects. These increases were partly offset by lower CBRNE revenue, which benefited from a significant contract in the year ended December 31, 2016.

        Bruker Nano Group revenue increased by $58.4 million to $513.0 million for the year ended December 31, 2017, compared to $454.6 million for the year ended December 31, 2016. The Bruker Nano Group revenue increase was primarily as a result of recent acquisitions, growth within the academic and industrial markets for X-ray and nano surfaces products and growth in semiconductor metrology markets.

        System revenue and aftermarket revenue as a percentage of total BSI Segment revenue were as follows during the years ended December 31, 2017 and 2016 (dollars in millions):

BEST Segment Revenues

        BEST Segment revenue increased by $61.0 million, or 46.9%, to $191.2 million for the year ended December 31, 2017, compared to $130.2 million for the year ended December 31, 2016. The increase in revenue resulted from the OST acquisition, which was completed in the fourth quarter of 2016, and organic revenue growth caused by higher shipments of superconductors to large magnetic resonance imaging customers.

        System and wire revenue and aftermarket revenue as a percentage of total BEST Segment revenue were as follows during the years ended December 31, 2017 and 2016 (dollars in millions):

Gross Profit and Operating Expenses

        For the year ended December 31, 2017, gross profit margin in the BSI Segment increased to 49.6% from 48.1% in the year ended December 31, 2016. The increase in gross margin was caused primarily by higher sales attributable to improved European and industrial end markets and operating cost improvements resulting from recent restructuring and operational initiatives. A product mix favoring less profitable lower field NMR systems within the BioSpin Group was an offset to the year over year BSI Segment gross margin expansion. The BEST Segment gross profit margin decreased to 15.3% from 17.1% for the year ended December 31, 2016. Lower gross margins resulted primarily from the impact of the OST acquisition. Integration plans for the BEST Segment's OST business include commercial and productivity improvement actions designed to achieve pre-acquisition gross profit margin levels.

        For the year ended December 31, 2017, selling, general and administrative expenses and research and development expenses in the BSI Segment increased to $557.8 million, or 35.2% of segment revenue, from $524.0 million, or 35.1% of segment revenue, for the comparable period in 2016. Selling, general and administrative expenses and research and development expenses in the BEST Segment increased to $20.7 million, or 10.8% of segment revenue, in 2017 compared to $15.5 million, or 11.9% of segment revenue, in 2016. The decrease in BEST Segment operating expenses as a percent of revenue was primarily attributable to the increased revenue during the year ended December 31, 2017.

Operating Income

        The following table presents operating income and operating margins on revenue by reportable segment for the years ended December 31, 2017 and 2016 (dollars in millions):

        BSI Segment operating income for the year ended December 31, 2017 was $208.6 million, resulting in an operating margin of 13.2%, compared to income from operations of $168.9 million, resulting in an operating margin of 11.3%, for the year ended December 31, 2016. Our operating margin increased primarily because of the gross profit improvements noted above, as well as operational improvements as a result of our restructuring initiatives.

        BEST Segment operating income for the year ended December 31, 2017 was $7.4 million, resulting in an operating margin of 3.9%, compared to operating income of $6.6 million, resulting in an operating margin of 5.1%, for the year ended December 31, 2016. The decrease in operating margin was primarily the result of the gross margin deterioration noted above.

Consolidated Results

        The following table presents our results for the years ended December 31, 2016 and 2015 (dollars in millions, except per share data):

Revenue

        For the year ended December 31, 2016, our revenue decreased by $12.5 million, or 0.8%, to $1,611.3 million, compared to $1,623.8 million for the year ended December 31, 2015. Included in revenue was an increase of approximately $32.4 million attributable primarily to the acquisition of Jordan Valley and a decrease of approximately $8.3 million from the impact of foreign currency translation caused by the strengthening of the U.S. Dollar versus the Euro, Swiss Franc and other

currencies. Excluding the effects of foreign currency translation and our recent acquisitions, our organic revenue, a non-GAAP measure, decreased by $36.6 million, or 2.3%.

Gross Profit

        Our gross profit for the year ended December 31, 2016 was $742.5 million, resulting in a gross profit margin of 46.1%, compared to $708.6 million, resulting in a gross profit margin of 43.6%, for the year ended December 31, 2015. The increase in our gross profit margin was caused primarily by operating cost improvements as a result of recent restructuring and operational initiatives, the impact of pricing increases and a favorable business mix within the Bruker BioSpin Group and the impact of the Jordan Valley acquisition. The favorable effect of these items was partially offset by weakness in Bruker Nano Group industrial market segments and delays in European academic funding within our Bruker CALID and Bruker Nano Groups during the first three quarters of 2016.

Selling, General and Administrative

        Our selling, general and administrative expenses for the year ended December 31, 2016 decreased to $390.5 million, or 24.2% of revenue, from $392.2 million, or 24.2% of revenue, for the year ended December 31, 2015. Selling, general and administrative expenses remained consistent as a percentage of revenue compared to the year ended December 31, 2015 as the favorable impacts of our outsourcing and restructuring initiatives was offset by additional expenses incurred related to our 2015 acquisition of Jordan Valley and other recent acquisitions.

Research and Development

        Our research and development expenses for the year ended December 31, 2016 increased to $149.0 million, or 9.2% of revenue, from $145.7 million, or 9.0% of revenue, for the year ended December 31, 2015. The increase was attributable to new initiatives related to our recent acquisitions and our expanded technological portfolio.

Other Charges, Net

        Other charges, net was $25.8 million for the year ended December 31, 2016, of which $25.2 million related to the BSI Segment and $0.6 million related to the BEST Segment. The charges consisted primarily of $9.8 million of restructuring costs related to closing facilities and implementing outsourcing and other restructuring initiatives, $9.0 million related primarily to additional contingent consideration recognized for Jordan Valley based upon an increase in revenue levels of the acquired business which increased the amount of expected earn out payments, $6.2 million of costs associated with our global information technology (IT) transformation initiative and impairment charges of $0.8 million comprised of other long-lived assets related to the restructuring actions within the Bruker CALID and Bruker Nano Groups during the year.

        Other charges, net was $25.0 million for the year ended December 31, 2015 and related almost entirely to the BSI Segment. The charges consisted primarily of a $10.2 million one-time, non-cash settlement charge as the plan assets and pension obligations for the retirees and other certain members of the population within our pension plan in Switzerland were transferred to an outside insurance provider, $8.1 million of restructuring costs related to closing facilities and implementing outsourcing and other restructuring initiatives, $8.9 million of costs associated with our global IT transformation initiative and impairment charges of $4.6 million comprised of goodwill, definite-lived intangible assets and other long-lived assets, related to the restructuring actions within the Bruker BioSpin Group, partially offset by ($7.2) million of contingent consideration reversals, as it was determined that certain financial targets related to the applicable acquisitions would not meet the required thresholds for payment.

Table of Contents

        At December 31, 2016 and 2015, we performed our annual goodwill and indefinite-lived intangible impairment evaluation and concluded the fair values of each of our reporting units were significantly greater than their carrying amounts, and therefore, no additional impairment is required.

Operating Income

        Operating income for the year ended December 31, 2016 was $177.2 million, resulting in an operating margin of 11.0%, compared to income from operations of $145.7 million, resulting in an operating margin of 9.0%, for the year ended December 31, 2015. The increase in operating margin was primarily attributable to the gross margin improvements discussed above, operating cost improvements as a result of our restructuring initiatives and prudent cost controls.

Interest and Other Income (Expense), Net

        Interest and other income (expense), net during the year ended December 31, 2016 was $0.4 million compared to ($17.7) million for the year ended December 31, 2015.

        During the year ended December 31, 2016, the major components within interest and other income (expense), net were a gain on acquisition of $9.2 million, realized and unrealized gains on foreign currency denominated transactions of $4.1 million, partially offset by net interest expense of $12.9 million. The $9.2 million gain on acquisition related to the acquisition of OST within the BEST Segment as the value of the assets purchased exceeded the consideration paid. During the year ended December 31, 2015, the major components within interest and other income (expense), net were net interest expense of $11.8 million and realized and unrealized losses on foreign currency denominated transactions of $5.5 million.

Income Tax Provision

        The income tax provision in each of the years ended December 31, 2016 and 2015 was $23.1 million, representing effective tax rates of 13.0% and 18.0%, respectively. The decrease in our effective tax rate for the year ended December 31, 2016, compared to 2015, was primarily attributable to the release of our remaining valuation allowances and the recognition of previously unrecognized tax benefits due to the closure of tax audits. Our tax rate may change over time as the amount and mix of jurisdictional income changes.

Net Income Attributable to Noncontrolling Interests

        Net income attributable to noncontrolling interests for the year ended December 31, 2016 was $0.9 million compared to $3.3 million for the year ended December 31, 2015. The net income attributable to noncontrolling interests represented the minority shareholders' proportionate share of the net income recorded by our majority-owned indirect subsidiaries.

Net Income Attributable to Bruker Corporation

        Our net income attributable to Bruker Corporation for the year ended December 31, 2016 was $153.6 million, or $0.95 per diluted share, compared to net income of $101.6 million, or $0.60 per diluted share, for 2015. The increase for the year ended December 31, 2016 was primarily caused by increased gross profit, operating profit improvements, a lower effective tax rate and the positive impact of foreign currency translation and our share repurchase program.

Segment Results

Revenue

        The following table presents revenue, change in revenue, and revenue growth by reportable segment for the years ended December 31, 2016 and 2015 (dollars in millions):

BSI Segment Revenues

        For financial reporting purposes, we aggregate the Bruker BioSpin, Bruker CALID and Bruker Nano operating segments into the Bruker Scientific Instruments (BSI) reportable segment, which represented approximately 93% of the Company's revenues during the year ended December 31, 2016. This aggregation reflects these operating segments' similar economic characteristics, production processes, customer services provided, types and classes of customers, methods of distribution and regulatory environments. Our BEST Segment is our other reportable segment and represents the remainder of our revenues.

        BSI Segment revenue decreased by $6.6 million, or 0.4%, to $1,492.6 million for the year ended December 31, 2016, compared to $1,499.2 million for the year ended December 31, 2015. Included in revenue was an increase of approximately $26.6 million related to the acquisition of Jordan Valley, offset in part by approximately $7.6 million from the impact of foreign currency translation caused by the strengthening of the U.S. Dollar versus the Euro, Swiss Franc and other currencies. Excluding the effects of foreign currency translation and our recent acquisitions, our organic revenue, a non-GAAP measure, decreased by $25.6 million, or 1.7%.

        Bruker BioSpin Group revenue increased by $15.7 million to $562.7 million for the year ended December 31, 2016, compared to $547.0 million for the year ended December 31, 2015. The Bruker BioSpin Group increase in revenue was primarily due to increased pricing and the recognition of revenues from the sale of the first shielded ultra-high field gigahertz nuclear magnetic resonance system.

        Bruker CALID Group revenue decreased by $17.2 million to $475.4 million for the year ended December 31, 2016, compared to $492.6 million for the year ended December 31, 2015. The Bruker CALID Group experienced lower revenue primarily due to delays in European academic funding in the first three quarters of 2016 and lower sales of our MALDI Biotyper in China and the United States in the first half of 2016.

        Bruker Nano Group revenue decreased by $5.2 million to $454.6 million for the year ended December 31, 2016, compared to $459.8 million for the year ended December 31, 2015. The Bruker Nano Group experienced lower revenue primarily due to delays in European academic funding in the first three quarters of 2016 as well as continued weaker demand within global industrial markets.

        BEST Segment revenue decreased by $3.5 million, or 2.6%, to $130.2 million for the year ended December 31, 2016, compared to $133.7 million for the year ended December 31, 2015. The decline in revenue was primarily attributable to the completion and final acceptance of the ROSATOM pilot line in Russia, and high margin customer projects (DESY particle acceleration and ITER magnetic fusion) in the year ended December 31, 2015.

        System and wire revenue and aftermarket revenue as a percentage of total BEST Segment revenue were as follows during the years ended December 31, 2016 and 2015 (dollars in millions):

Gross Profit and Operating Expenses

        For the year ended December 31, 2016, gross profit margin in the BSI Segment increased to 48.1% from 45.5% in the year ended December 31, 2015. The increase in gross margin percentage was caused primarily by operating cost improvements resulting from recent restructuring and operational initiatives, the impact of pricing increases within the Bruker BioSpin Group and the impact of the Jordan Valley acquisition within the Bruker Nano Group. These effects were partially offset by revenue weakness in certain Bruker Nano and Bruker CALID Group market segments resulting from delays in European academic funding during the first three quarters of 2016. The BEST Segment gross profit margin decreased to 17.1% from 19.5% for the year ended December 31, 2015. Lower gross margins resulted primarily from the completion of the ROSATOM pilot line and the DESY and ITER orders in 2015.

        For the year ended December 31, 2016, selling, general and administrative expenses and research and development expenses in the BSI Segment remained consistent at $524.0 million, or 35.1% of segment revenue, from $524.2 million, or 35.0% of segment revenue, for the comparable period in 2015. Selling, general and administrative expenses and research and development expenses in the BEST Segment increased to $15.5 million, or 11.9% of segment revenue, in 2016 compared to $13.7 million, or 10.2% of segment revenue, in 2015. The increase in BEST Segment operating expenses was primarily attributable to increased costs associated with selective research and development initiatives.

Operating Income

        The following table presents operating income and operating margins on revenue by reportable segment for the years ended December 31, 2016 and 2015 (dollars in millions):

        BSI operating income for the year ended December 31, 2016 was $168.9 million, resulting in an operating margin of 11.3%, compared to income from operations of $133.2 million, resulting in an operating margin of 8.9%, for the year ended December 31, 2015. Our operating margin increased primarily because of the gross profit improvements noted above, as well as operational improvements as a result of our restructuring initiatives.

        BEST operating income for the year ended December 31, 2016 was $6.6 million, resulting in an operating margin of 5.1%, compared to operating income of $11.5 million, resulting in an operating margin of 8.6%, for the year ended December 31, 2015. The decrease in operating margin is primarily the result of the decreased gross margins as a result of the completion of the ROSATOM pilot line and the DESY and ITER projects in 2015.

LIQUIDITY AND CAPITAL RESOURCES

        We currently anticipate that our existing cash and credit facilities will be sufficient to support our operating and investing needs for at least the next twelve months. Our future cash requirements could be affected by acquisitions that we may complete, repurchases of our common stock, or the payment of dividends in the future. Historically, we have financed our growth and liquidity needs through cash flow generation and a combination of debt financings and issuances of common stock. In the future, there are no assurances that additional financing alternatives will be available to us, if required, or if available, will be obtained on terms favorable to us.

        During the year ended December 31, 2017, net cash provided by operating activities was $154.4 million, resulting primarily from consolidated net income adjusted for non-cash items of $195.0 million, offset by a net increase in operating assets and liabilities, net of acquisitions and divestitures, of $40.6 million. The increase in operating assets and liabilities, net of acquisitions and divestitures, for the year ended December 31, 2017 was primarily caused by an increase in accounts receivables caused by proportionately higher sales late in the fourth quarter of 2017, which was offset in part by the income tax accruals in the fourth quarter of 2017 related to U.S. tax reform legislation, as well as higher compensation and restructuring accruals.

        During the year ended December 31, 2016, net cash provided by operating activities was $130.8 million, resulting primarily from consolidated net income adjusted for non-cash items of $219.6 million, offset by a net increase in operating assets and liabilities, net of acquisitions and divestitures, of $88.8 million. The increase in operating assets and liabilities, net of acquisitions and divestitures, for the year ended December 31, 2016 was primarily caused by the timing of customer payments, as the fourth quarter of 2015 included higher than normal collections of receivables, an increase in inventory in 2016 as a result of inventory build for 2017 orders with the Bruker BioSpin

Cash used in investing activities during the year ended December 31, 2017 was primarily due to the net cash paid for acquisitions of $66.3 million and net capital expenditures of $32.2 million. These activities were offset, in part, by net cash proceeds of short-term investments of $68.3 million. During the year ended December 31, 2016, net cash used in investing activities was $21.8 million, compared to net cash used in investing activities of $102.4 million during the year ended December 31, 2015. Cash used in investing activities during the year ended December 31, 2016 was primarily caused by net capital expenditures of $36.0 million and cash paid for acquisitions, net of cash acquired, of $24.3 million offset, in part, by maturities, net of purchases, of short-term investments of $38.5 million.

        We expect capital expenditures in 2018 to amount to approximately $50.0 million.

        During the year ended December 31, 2017, net cash used in financing activities was $159.0 million, compared to net cash used in financing activities of $27.9 million during the year ended December 31, 2016. Cash used in financing activities during the year ended December 31, 2017 was primarily caused by the repurchase of common stock of $152.2 million, $130.0 million of repayments under the revolving line of credit, $25.4 million used for the payment of dividends and $20.0 million of repayments under the Note Purchase Agreement. These cash uses were partially offset by borrowings of $154.0 million under the revolving line of credit and $20.0 million of proceeds from the issuance of common stock in connection with stock option exercises. Cash used in financing activities during the year ended December 31, 2016 was primarily caused by the repurchase of common stock of $160.0 million and $25.8 million used for the payment of dividends, partially offset by borrowings of $146.0 million under the revolving line of credit and $11.5 million of proceeds from the issuance of common stock in connection with stock option exercises.

        In May 2017, our Board of Directors approved a share repurchase program (the "Repurchase Program") under which repurchases of common stock in the amount of up to $225.0 million may occur from time to time, in amounts, at prices, and at such times as we deem appropriate, subject to market conditions, legal requirements and other considerations. A total of 5,318,063 shares were repurchased at an aggregate cost of $152.2 million as of December 31, 2017 under this Repurchase Program. We intend to fund any additional repurchases from cash on hand, future cash flows from operations and available borrowings under our revolving credit facility.

        The repurchased shares are reflected within Treasury stock in the accompanying consolidated balance sheet at December 31, 2017.

        Cash, cash equivalents and short-term investments at December 31, 2017 and 2016 totaled $439.2 million and $500.3 million, respectively, of which $405.8 million and $460.9 million, respectively, related to cash, cash equivalents and short-term investments held outside of the U.S. in our foreign subsidiaries, most significantly in the Netherlands and Switzerland.

        At December 31, 2017 and in accordance with the 2017 Tax Act, we recorded state and foreign withholding taxes on the cash and liquid assets portion of the unremitted earnings and profits (E&P) of foreign subsidiaries expected to be repatriated from its foreign subsidiaries to the United States. We continue to be indefinitely reinvested amounting to $740.0 million of non-cash E&P that is related to the 2017 Tax Act deemed repatriation. If this E&P is ultimately distributed to the United States in the form of dividends or otherwise we would likely be subject to additional withholding tax. We will continue to evaluate our assertions on the cumulative historical outside basis differences in our foreign subsidiaries as of December 31, 2017. We expect to finalize its analysis and accounting related to the toll charge and any remaining outside basis differences in our foreign subsidiaries during the

measurement period. We estimate the amount of unrecognized deferred withholding taxes on the undistributed E&P to be approximately $27 million at December 31, 2017.

        As of December 31, 2017, we had approximately $23.2 million of net operating loss carryforwards available to reduce state taxable income. We also had approximately $77.4 million of German Trade Tax and Corporate Income Tax net operating losses that are carried forward indefinitely. Additionally, we had $13.9 million of other foreign net operating losses that are expected to expire at various times beginning in 2018. We also had state research and development tax credits of $7.5 million. Utilization of these credits and state net operating losses may be subject to annual limitations due to the ownership percentage change limitations provided by the Internal Revenue Code Section 382 and similar state provisions. In the event of a deemed change in control under Internal Revenue Code Section 382, an annual limitation on the utilization of net operating losses and credits may result in the expiration of all or a portion of the net operating loss and credit carryforwards.

        Uncertain tax contingencies are positions taken or expected to be taken on an income tax return that may result in additional payments to tax authorities. If a tax authority agrees with the tax position taken or expected to be taken or the applicable statute of limitations expires, then additional payments will not be necessary.

        At December 31, 2017, we had outstanding debt totaling $415.6 million, consisting of $220.0 million outstanding under the Note Purchase Agreement described below, $195.0 million outstanding under the revolving loan component of the 2015 Credit Agreement described below and $1.3 million under capital lease obligations and other loans. These amounts were offset by unamortized debt issuance costs under the Note Purchase Agreement of $0.7 million. At December 31, 2016, we had outstanding debt totaling $411.7 million, consisting of $240.0 million outstanding under the Note Purchase Agreement described below, $171.0 million outstanding under the revolving loan component of the 2015 Credit Agreement described below and $1.5 million under capital lease obligations and other loans. These amounts were offset by unamortized debt issuance costs under the Note Purchase Agreement of $0.8 million.

        The following is a summary of the maximum commitments and the net amounts available to us under the 2015 Credit Agreement and other lines of credit with various financial institutions located primarily in Germany and Switzerland that are unsecured and typically due upon demand with interest payable monthly, at December 31, 2017 (in millions):

        On October 27, 2015, we entered into a revolving credit agreement, referred to as the 2015 Credit Agreement, and terminated the prior credit agreement. The 2015 Credit Agreement provides a maximum commitment on the revolving credit line of $500.0 million and a maturity date of October 2020. Borrowings under the revolving credit line of the 2015 Credit Agreement accrue interest, at the Company's option, at either (a) the greatest of (i) the prime rate, (ii) the federal funds rate plus 0.50%, and (iii) adjusted LIBOR plus 1.00%, plus margins ranging from 0.00% to 0.30% or (b) LIBOR, plus margins ranging from 0.90% to 1.30%. There is also a facility fee ranging from 0.10% to 0.20%.

        Borrowings under the 2015 Credit Agreement are secured by guarantees from certain material subsidiaries, as defined in the 2015 Credit Agreement. The 2015 Credit Agreement also requires us to maintain certain financial ratios related to maximum leverage and minimum interest coverage.

Table of Contents

Specifically, our leverage ratio cannot exceed 3.5 and our interest coverage ratio cannot be less than 2.5. In addition to the financial ratios, the 2015 Credit Agreement contains negative covenants, including among others, restrictions on liens, indebtedness of the Company and its subsidiaries, asset sales, dividends and transactions with affiliates. Failure to comply with any of these restrictions or covenants may result in an event of default on the 2015 Credit Agreement, which could permit acceleration of the debt and require us to prepay the debt before its scheduled due date.

        As of December 31, 2017, we were in compliance with the covenants, as defined by the 2015 Credit Agreement, as our leverage ratio was 1.32 and our interest coverage ratio was 15.5.

        In January 2012, we entered into a note purchase agreement, referred to as the Note Purchase Agreement, with a group of accredited institutional investors. Under the Note Purchase Agreement we issued and sold $240.0 million of senior notes, which consist of the following:

•

$20.0 million 3.16% Series 2012A senior notes due January 18, 2017;



•

$15.0 million 3.74% Series 2012A senior notes due January 18, 2019;



•

$105.0 million 4.31% Series 2012A senior notes due January 18, 2022; and



•

$100.0 million 4.46% Series 2012A senior notes due January 18, 2024.

        On January 18, 2017, the outstanding $20.0 million principal amount of Tranche A of the Senior Notes was repaid in accordance with the terms of the Note Purchase Agreement.

        Under the terms of the Note Purchase Agreement, we may issue and sell additional senior notes up to an aggregate principal amount of $600 million, subject to certain conditions. Interest on the Senior Notes is payable semi-annually on January 18 and July 18 of each year. The Senior Notes are unsecured obligations of ours and are fully and unconditionally guaranteed by certain of our direct and indirect subsidiaries. The Senior Notes rank pari passu in right of repayment with our other senior unsecured indebtedness. We may prepay some or all of the Senior Notes at any time in an amount not less than 10% of the original aggregate principal amount of the Senior Notes to be prepaid, at a price equal to the sum of (a) 100% of the principal amount thereof, plus accrued and unpaid interest, and (b) the applicable make-whole amount, upon not less than 30 and no more than 60 days written notice to the holders of the Senior Notes. In the event of a change in control of the Company, as defined in the Note Purchase Agreement, we may be required to prepay the Notes at a price equal to 100% of the principal amount thereof, plus accrued and unpaid interest.

        The Note Purchase Agreement contains affirmative covenants, including, without limitation, maintenance of corporate existence, compliance with laws, maintenance of insurance and properties, payment of taxes, addition of subsidiary guarantors and furnishing notices and other information. The Note Purchase Agreement also contains certain restrictive covenants that restrict our ability to, among other things, incur liens, transfer or sell assets, engage in certain mergers and consolidations and enter into transactions with affiliates. The Note Purchase Agreement also includes customary representations and warranties and events of default. In the case of an event of default arising from specified events of bankruptcy or insolvency, all outstanding Senior Notes will become due and payable immediately without further action or notice. In the case of payment events of defaults, any holder of Senior Notes affected thereby may declare all Senior Notes held by it due and payable immediately. In the case of any other event of default, a majority of the holders of the Senior Notes may declare all the Senior Notes to be due and payable immediately. Pursuant to the Note Purchase Agreement, so long as any Senior Notes are outstanding we will not permit (i) our leverage ratio, as determined pursuant to the Note Purchase Agreement, as of the end of any fiscal quarter to exceed 3.50 to 1.00, (ii) our interest coverage ratio as determined pursuant to the Note Purchase Agreement as of the end of any fiscal quarter for any period of four consecutive fiscal quarters to be less than 2.50 to 1 or (iii) priority debt

at any time to exceed 25% of consolidated net worth, as determined pursuant to the Note Purchase Agreement.

        As of December 31, 2017, we were in compliance with the covenants of the Note Purchase Agreement. Our leverage ratio (as defined in the Note Purchase Agreement) was 1.32 and our interest coverage ratio (as defined in the Note Purchase Agreement) was 15.5.

        The following table summarizes maturities for our significant financial obligations as of December 31, 2017 (dollars in millions):

CRITICAL ACCOUNTING POLICIES AND ESTIMATES

        This discussion and analysis of our financial condition and results of operations is based upon our consolidated financial statements, which have been prepared in accordance with accounting principles generally accepted in the United States of America, or U.S. GAAP. The preparation of these financial statements requires that we make estimates and assumptions that affect the reported amounts of assets and liabilities and the disclosure of contingent assets and liabilities at the date of the financial statements and reported amounts of revenues and expenses during the reporting period. On an ongoing basis, management evaluates its estimates and judgments, including those related to: revenue recognition; the expensing and capitalization of software development costs; stock-based compensation expense; restructuring and other related charges; income taxes, including the recoverability of deferred tax assets; allowances for doubtful accounts; inventory reductions for excess and obsolete inventories; estimated fair values of long-lived assets used to measure the recoverability of long-lived assets; intangible assets and goodwill; expected future cash flows used to measure the recoverability of intangible assets and long-lived assets; warranty costs; derivative financial instruments; and contingent liabilities. We base our estimates and judgments on our historical experience, current market and economic conditions, industry trends, and other assumptions that we believe are reasonable and form

the basis for making judgments about the carrying value of assets and liabilities that are not readily apparent from other sources. Actual results could differ from these estimates.

        We believe the following critical accounting policies and estimates to be both those most important to the portrayal of our financial position and results of operations and those that require the most estimation and subjective judgment.

        Revenue recognition.    We recognize revenue from system sales when persuasive evidence of an arrangement exists, the price is fixed or determinable, title and risk of loss has been transferred to the customer, and collectability of the resulting receivable is reasonably assured. Title and risk of loss generally transfers upon shipment, or for certain systems, based upon customer acceptance for a system that has been delivered to the customer and installed at a customer facility. For systems that include customer-specific acceptance criteria, we are required to assess when we can demonstrate the acceptance criteria has been met, which generally is upon successful factory acceptance testing or customer acceptance and evidence of installation.

        When products are sold through an independent distributor or a strategic distribution partner who assumes responsibility for installation, we recognize the system sale when the product has been shipped and title and risk of loss have been transferred to the distributor. Our distributors do not have price protection rights or rights of return; however, our products are typically warranted to be free from defect for a period of one year. Revenue is deferred until cash is received when collectability is not reasonably assured or when the price is not fixed or determinable.

        For transactions that include multiple elements, arrangement consideration is allocated to each element using the fair value hierarchy as required by ASU No. 2009-13. We limit the amount of revenue recognized for delivered elements to the amount that is not contingent on the future delivery of products or services, future performance obligations, or subject to customer-specific return or refund privileges.

        We determine the fair value of products and services based upon vendor specific objective evidence ("VSOE"). We determine VSOE based on normal selling pricing and discounting practices for the specific product or service when sold on a stand-alone basis. In determining VSOE, our policy requires a substantial majority of selling prices for a product or service to be within a reasonably narrow range. We also consider the class of customer, method of distribution and the geographies into which products and services are being sold when determining VSOE.

        If VSOE cannot be established, we attempt to establish the selling price based on third-party evidence ("TPE"). VSOE cannot be established in instances where a product or service has not been sold separately, stand-alone sales are too infrequent or product pricing is not within a sufficiently narrow range. TPE is determined based on competitor prices for similar deliverables when sold separately.

        When we cannot determine VSOE or TPE, we use estimated selling price ("ESP") in our allocation of arrangement consideration. The objective of ESP is to determine the price at which we would typically transact a stand-alone sale of the product or service. ESP is determined by considering a number of factors including our pricing policies, internal costs and gross profit objectives, method of distribution, market research and information, recent technological trends, competitive landscape and geographies. We analyze the selling prices used in our allocation of arrangement consideration, at a minimum, on an annual basis. Selling prices will be analyzed more frequently if a significant change in our business occurs or other factors necessitate more frequent analysis, or if we experience significant variances in our selling prices.

        Revenue from accessories and consumable parts is generally recognized upon shipping terms. Service revenue is recognized as the services are performed or ratably over the contractual obligation

62

and includes maintenance contracts, extended warranty, training, application support and on-demand services.

        We also have contracts for which we apply the percentage-of-completion model and completed contract model of revenue recognition. Application of the percentage-of-completion method requires us to make reasonable estimates of the extent of progress toward completion of the contract and the total costs we will incur under the contract and losses are recorded immediately when we estimate that contracts will ultimately result in a loss. Changes in the estimates could affect the timing of revenue recognition.

        Other revenues are primarily comprised of development arrangements recognized on a cost-plus-fixed-fee basis and licensing arrangements recognized ratably over the term of the related contracts.

        Income taxes.    The determination of income tax expense requires us to make certain estimates and judgments concerning the annual effective tax rate, the calculation of deferred tax assets and liabilities, the forecasted profitability of our subsidiaries in certain geographic jurisdictions, as well as the deductions, carryforwards and credits that are available to reduce taxable income. Deferred tax assets and liabilities arise from differences in the timing of the recognition of revenue and expenses for financial statement and tax purposes. Deferred tax assets and liabilities are measured using the tax rates in effect for the year in which these temporary differences are expected to be settled. We estimate the degree to which tax assets and loss carryforwards will result in a benefit based on expected profitability by tax jurisdiction, and we provide a valuation allowance for tax assets and loss carryforwards that we believe will more likely than not go unused. If it becomes more likely than not that a tax asset or loss carryforward will be used for which a valuation allowance has been provided, we reverse the related valuation allowance. If our actual future taxable income by tax jurisdiction differs from estimates, additional allowances or reversals of a valuation allowance may be necessary. In addition, we only recognize benefits for tax positions that we believe are more likely than not of being sustained upon review by a taxing authority with knowledge of all relevant information. We reevaluate our uncertain tax positions on a quarterly basis and any changes to these positions as a result of tax audits, tax laws or other facts and circumstances could result in additional charges or credits to operations. The expiration of statutes of limitations affecting estimates made for uncertain tax positions can cause higher earnings.

        On December 22, 2017 (Enactment Date), the President of the United States signed tax reform legislation (2017 Tax Act), which enacted a wide range of changes to the U.S. corporate income tax system, many of which differ significantly from the provisions of the previous U.S. tax law. We have not yet completed the assessment of the tax effects associated with the enactment of the 2017 Tax Act; however, a reasonable estimate has been made of the effects on the existing deferred tax balances and the one-time transition tax. Changes in the tax rates and laws are accounted for in the period of enactment. The actual results of the implementation of the 2017 Tax Act may materially differ from our current estimate due to, among other things, further guidance that may be issued by U.S. tax authorities or regulatory bodies including the SEC and the FASB to interpret the 2017 Tax Act. We will continue to analyze the 2017 Tax Act and any additional guidance that may be issued and finalize the full effects of applying the new legislation in the measurement period.

        Inventories.    Inventories are stated at the lower of cost and net realizable value, with costs determined by the first-in, first-out method for a majority of subsidiaries and by average cost for certain other subsidiaries. We record provisions to account for excess and obsolete inventory to reflect the expected non-saleable or non-refundable inventory based on an evaluation of slow moving products or products no longer offered for sale. Inventories also include demonstration units located in our demonstration laboratories or installed at the sites of potential customers. We consider our demonstration units to be available for sale and have a history of selling these demonstration units. We

63

Table of Contents

reduce the carrying value of demonstration inventories for differences between cost and estimated net realizable value, taking into consideration usage in the preceding twelve months, expected demand, technological obsolescence and other information including the physical condition of the unit. If ultimate usage or demand varies significantly from expected usage or demand, additional write-downs may be required, resulting in additional charges to operations.

        Goodwill, other intangible assets and other long-lived assets.    We evaluate goodwill for impairment annually and when events occur or circumstances change. We test goodwill for impairment at the reporting unit level, which is the operating segment or one level below an operating segment. Under U.S. GAAP, we have the option of performing a qualitative assessment to determine whether further impairment testing is necessary before performing a two-step quantitative assessment. The qualitative assessment requires significant judgments about macro-economic conditions including the entity's operating environment; its industry and other market considerations; entity-specific events related to financial performance or loss of key personnel; and other events that could impact the reporting unit. If, as a result of our qualitative assessment, it is more-likely-than-not that the fair value of a reporting unit is less than its carrying amount, the quantitative impairment test will be required. Otherwise, no further testing is required. If a quantitative impairment test is performed, the first step involves comparing the fair values of the applicable reporting units with their aggregate carrying values, including goodwill. We generally determine the fair value of our reporting units using a weighting of both the market approach and the income approach methodologies. The income approach valuation methodology includes discounted cash flow estimates. Estimating the fair value of the reporting units requires significant judgment about the future cash flows. If the carrying amount of a reporting unit exceeds the fair value of the reporting unit, we perform the second step of the goodwill impairment test to measure the amount of the impairment. In the second step of the goodwill impairment test, we compare the implied fair value of the reporting unit's goodwill with the carrying value of that goodwill. At December 31, 2017, we performed our annual goodwill and indefinite-lived intangible impairment evaluation using a qualitative impairment test and concluded the fair values of each of our reporting units were significantly greater than their carrying amounts, and therefore, no additional impairment was required.

        We also review definite-lived intangible assets and other long-lived assets when indications of potential impairment exist. Should the fair value of our long-lived assets decline because of reduced operating performance, market declines or other indicators of an impairment, a charge to operations for impairment may be necessary.

RECENT ACCOUNTING PRONOUNCEMENTS

        In January 2017, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") 2017-04, Intangibles-Goodwill and Other (Topic 350): Simplifying the Test for Goodwill Impairment. The new standard simplifies the subsequent measurement of goodwill by eliminating the second step of the goodwill impairment test. This ASU will be applied prospectively and is effective for annual or interim goodwill impairment tests in fiscal years beginning after December 15, 2019. The adoption of this standard is not expected to have a material impact on our financial position, results of operations or statements of cash flows upon adoption.

        In January 2017, the FASB issued ASU No. 2017-01, Business Combinations (Topic 805): Clarifying the Definition of a Business. This new standard clarifies the definition of a business and provides a screen to determine when an integrated set of assets and activities is not a business. The screen requires that when substantially all of the fair value of the gross assets acquired (or disposed of) is concentrated in a single identifiable asset or a group of similar identifiable assets, the set is not a business. This new standard was adopted as of the effective date of January 1, 2018. We have evaluated the provisions of this standard and have determined that the impact of adoption of ASU No. 2017-01 was not material to our consolidated financial statements.

64

---

Table of Contents

        In October 2016, the FASB issued ASU No. 2016-16, Income Taxes (Topic 740)—Intra-Entity Transfer of Assets Other than Inventory. The new standard requires recognition of current and deferred income taxes resulting from an intra-entity transfer of any asset (excluding inventory) when the transfer occurs. This is a change from existing U.S. GAAP which prohibits recognition of current and deferred income taxes until the asset is sold to a third party. This new standard was adopted as of the effective date of January 1, 2018. We have evaluated the provisions of this standard and have determined that the impact of adoption of ASU No. 2016-16 was not material to our consolidated financial statements.

        In February 2016, the FASB issued ASU No. 2016-02, Leases. The new standard provides guidance on the recognition, measurement, presentation, and disclosure of leases. The new standard supersedes present U.S. GAAP guidance on leases and requires substantially all leases to be reported on the balance sheet as right-of-use assets and lease liabilities, as well as additional disclosures. The new standard is effective as of January 1, 2019, and early adoption is permitted. We are evaluating the provisions of this standard, including which period to adopt, and have not determined what impact the adoption of ASU No. 2016-02 will have on our consolidated financial statements.

        In May 2014, the FASB issued ASU No. 2014-09, Revenue from Contracts with Customers, which supersedes the revenue recognition requirements under Accounting Standards Codification (ASC) Topic 605. The new guidance was the result of a joint project between the FASB and the International Accounting Standards Board to clarify the principles for recognizing revenue and to develop common revenue standards for U.S. GAAP and International Financial Reporting Standards. The core principle of the new guidance is that revenue should be recognized to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. In August 2015, the FASB elected to defer the effective date of ASU No. 2014-09 by one year to annual periods beginning after December 15, 2017, with early application permitted as of the original effective date. The new guidance may be applied on a retrospective basis for all prior periods presented, or on a modified retrospective basis with the cumulative effect of the new guidance as of the date of initial application. The new guidance will be effective for us as of January 1, 2018 and we currently intend to use the modified retrospective transition method.

        We have substantially completed the impact assessment phase of our evaluation of ASU No. 2014-09. Under the new guidance, there are specific criteria to determine if a performance obligation should be recognized over time or at a point in time. Accordingly, we have identified certain project-based orders in the BEST Segment and CBRNE detection orders in the Bruker CALID Group for which the timing of when we recognize revenue may be impacted. Due to the complexity of these project-based orders, revenue recognition under the new standard is highly dependent on specific contract terms.

        During the fourth quarter of 2017, we have substantially completed the assessment over the impact that this new standard will have on our consolidated balance sheets. We preliminarily expect to recognize an adjustment of approximately $6.0 million to retained earnings on January 1, 2018 to reflect the cumulative effect of the accounting changes made upon the adoption of the standard. The finalization of the assessment may result in significant changes to the estimates that may materially impact the preliminary estimate of the cumulative effect.

TRANSACTIONS WITH RELATED PARTIES

        We lease certain office space from certain of our principal shareholders, including a director and executive officer and another member of our Board of Directors, and members of their immediate families, which have expiration dates ranging from 2017 to 2020. Total rent expense under these leases was $3.5 million, $3.9 million and $1.8 million for the years ended December 31, 2017, 2016 and 2015, respectively.

Table of Contents

        During the years ended December 31, 2017, 2016 and 2015, we recorded revenue of $2.6 million, $1.1 million and $0.7 million, respectively, arising from commercial transactions with a life sciences company in which a member of our Board of Directors is Chairman and Chief Executive Officer.

        During the year ended December 31, 2016 and 2015, we recorded revenue of $0.2 million and $0.5 million, respectively from commercial transactions with a thermal analysis company for which a member of our Board of Directors serves as a consultant.

ITEM 7A    QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

        We are potentially exposed to market risks associated with changes in foreign currency translation rates, interest rates and commodity prices. We selectively use financial instruments to reduce these risks. All transactions related to risk management techniques are authorized and executed pursuant to our policies and procedures. Analytical techniques used to manage and monitor foreign currency translation and interest rate risk include market valuations and sensitivity analysis.

Impact of Foreign Currencies

        We generate a substantial portion of our revenues in international markets, principally Germany and other countries in the European Union, Switzerland and Japan, which exposes our operations to the risk of exchange rate fluctuations. The impact of currency exchange rate movement can be positive or negative in any period. Our costs related to sales in foreign currencies are largely denominated in the same respective currencies, limiting our transaction risk exposure. However, for foreign currency denominated sales in certain regions, such as Japan, where we do not incur significant costs denominated in Japanese Yen, we are more exposed to the impact of foreign currency fluctuations. For sales not denominated in U.S. Dollars, if there is an increase in the rate at which a foreign currency is exchanged for U.S. Dollars, it will require more of the foreign currency to equal a specified amount of U.S. Dollars than before the rate increase. In such cases, if we price our products in the foreign currency, we will receive less in U.S. Dollars than we would have received before the rate increase went into effect. If we price our products in U.S. Dollars and competitors price their products in local currency, an increase in the relative strength of the U.S. Dollar could result in our prices not being competitive in a market where business is transacted in the local currency. In the years ended December 31, 2017 and 2016 our revenue by geography was as follows (dollars in millions):

        Changes in foreign currency exchange rates increased our revenue by approximately 1.2% in the year ended December 31, 2017 and decreased our revenue by approximately 0.5% in the year ended December 31, 2016.

        Assets and liabilities of our foreign subsidiaries, where the functional currency is the local currency, are translated into U.S. Dollars using year-end exchange rates, or historical rates, as appropriate. Revenues and expenses of foreign subsidiaries are translated at the average exchange rates in effect during the year. Adjustments resulting from financial statement translations are included as a separate component of shareholders' equity. In the year ended December 31, 2017, we recorded net gains from currency translation adjustments of $97.1 million. In the year ended December 31, 2016, we

66

---

Table of Contents

recorded net losses from currency translation of $27.6 million. A 10% depreciation in functional currencies, relative to the U.S. Dollar, at December 31, 2017, would have resulted in a reduction of shareholders' equity of approximately $137.2 million.

        Gains and losses resulting from foreign currency transactions are reported in interest and other income (expense), net in the consolidated statements of income and comprehensive income. Our foreign currency translation gains (losses), net were ($5.5) million and $4.1 million for years ended December 31, 2017 and 2016, respectively.

        From time to time, we have entered into foreign currency contracts in order to minimize the volatility that fluctuations in exchange rates have on our cash flows related to purchases and sales denominated in foreign currencies. Under these arrangements, we agree to purchase a fixed amount of a foreign currency in exchange for a fixed amount of U.S. Dollars or other currencies on specified dates, typically with maturities of less than twelve months. These transactions do not qualify for hedge accounting and, accordingly, the instrument is recorded at fair value with the corresponding gains and losses recorded in interest and other income (expense), net in the consolidated statements of income and comprehensive income.

        At December 31, 2017 and 2016, we had foreign currency contracts with notional amounts aggregating $84.2 million and $40.7 million, respectively. At December 31, 2017, the Company had the following notional amounts outstanding under foreign currency contracts (in millions):

        Based on the contractual maturities of these contracts and exchange rates as of December 31, 2017, we anticipate that these contracts will result in net cash inflows of $4.4 million in 2018. At December 31, 2017, assuming all other variables are constant, if the U.S. Dollar weakened by 10%, the market value of our foreign currency contracts would have increased by approximately $8.6 million and if the U.S. Dollar strengthened by 10%, the market value of our foreign currency contracts would have decreased by approximately $8.6 million.

        We will continue to evaluate our currency risks and in the future may utilize foreign currency contracts more frequently as part of a transactional hedging program.

Impact of Interest Rates

        We regularly invest excess cash in short-term investments that are subject to changes in interest rates. We believe that the market risk arising from holding these financial instruments is minimal because of our policy of investing in short-term financial instruments issued by highly rated financial institutions.

        Our exposure related to adverse movements in interest rates is derived primarily from outstanding floating rate debt instruments that are indexed to short-term market rates. We currently have approximately equal levels of fixed and floating rate debt, which limits our exposure to adverse movements in interest rates.

Impact of Commodity Prices

        We are exposed to certain commodity risks associated with prices for various raw materials. The prices of copper and certain other raw materials, particularly niobium-tin, used to manufacture superconductors have increased significantly over the last decade. Copper and niobium-tin are the main components of low temperature superconductors and continued commodity price increases for copper and niobium, as well as other raw materials, may negatively affect our profitability. Periodically, we enter into commodity forward purchase contracts to minimize the volatility that fluctuations in the price of copper have on our sales of these products. At December 31, 2017 and 2016, we had fixed price commodity contracts with notional amounts aggregating $3.0 million and $2.7 million, respectively. The fair value of the fixed price commodity contracts at December 31, 2017 and 2016 was $0.8 million and $0.2 million, respectively. We will continue to evaluate our commodity risks and may utilize commodity forward purchase contracts more frequently in the future.

Inflation

        We do not believe inflation had a material impact on our business or operating results during any of the periods presented.

Report of Independent Registered Public Accounting Firm

To the Board of Directors and Shareholders of
Bruker Corporation

Opinions on the Financial Statements and Internal Control over Financial Reporting

        We have audited the accompanying consolidated balance sheets of Bruker Corporation and its subsidiaries as of December 31, 2017 and 2016, and the related consolidated statements of income and comprehensive income, of shareholders' equity, and of cash flows for the years then ended, including the related notes (collectively referred to as the "consolidated financial statements"). We also have audited the Company's internal control over financial reporting as of December 31, 2017, based on criteria established in Internal Control—Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO).

        In our opinion, the consolidated financial statements referred to above present fairly, in all material respects, the financial position of the Company as of December 31, 2017 and 2016, and the results of their operations and their cash flows for the years then ended in conformity with accounting principles generally accepted in the United States of America. Also in our opinion, the Company maintained, in all material respects, effective internal control over financial reporting as of December 31, 2017, based on criteria established in Internal Control—Integrated Framework (2013) issued by the COSO.

Change in Accounting Principles

        As discussed in Notes 6 and 16 to the consolidated financial statements, respectively, the Company changed the manner in which it accounts for the measurement of inventory and the manner in which it accounts for the income tax effects of share based payment transactions in 2017.

Basis for Opinions

        The Company's management is responsible for these consolidated financial statements, for maintaining effective internal control over financial reporting, and for its assessment of the effectiveness of internal control over financial reporting, included in Management's Report on Internal Control over Financial Reporting appearing under Item 9A. Our responsibility is to express opinions on the Company's consolidated financial statements and on the Company's internal control over financial reporting based on our audits. We are a public accounting firm registered with the Public Company Accounting Oversight Board (United States) ("PCAOB") and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

        We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audits to obtain reasonable assurance about whether the consolidated financial statements are free of material misstatement, whether due to error or fraud, and whether effective internal control over financial reporting was maintained in all material respects.

        Our audits of the consolidated financial statements included performing procedures to assess the risks of material misstatement of the consolidated financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the consolidated financial statements. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the consolidated financial statements. Our audit of internal control over financial reporting included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, and testing and

70

---

Table of Contents

evaluating the design and operating effectiveness of internal control based on the assessed risk. Our audits also included performing such other procedures as we considered necessary in the circumstances. We believe that our audits provide a reasonable basis for our opinions.

        As described in Management's Report on Internal Control over Financial Reporting, management has excluded Hysitron, Incorporated ("Hysitron") from its assessment of internal control over financial reporting as of December 31, 2017 because it was acquired by the Company in a purchase business combination during 2017. We have also excluded Hysitron from our audit of internal control over financial reporting. Hysitron is a wholly-owned subsidiary whose total assets and total revenues excluded from management's assessment and our audit of internal control over financial reporting represent 0.7% and 0.9%, respectively, of the related consolidated financial statement amounts as of and for the year ended December 31, 2017.

Definition and Limitations of Internal Control over Financial Reporting

        A company's internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A company's internal control over financial reporting includes those policies and procedures that (i) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (ii) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and (iii) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the company's assets that could have a material effect on the financial statements.

        Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

Note 1—Description of Business

        Bruker Corporation, together with its consolidated subsidiaries ("Bruker" or the "Company"), develops, manufactures and distributes high-performance scientific instruments and analytical and diagnostic solutions that enable its customers to explore life and materials at microscopic, molecular and cellular levels. Many of the Company's products are used to detect, measure and visualize structural characteristics of chemical, biological and industrial material samples. The Company's products address the rapidly evolving needs of a diverse array of customers in life science research, pharmaceuticals, biotechnology, applied markets, cell biology, clinical research, microbiology, in-vitro diagnostics, nanotechnology and materials science research.

        The Company has two reportable segments, Bruker Scientific Instruments (BSI), which represented approximately 90% and 93% of the Company's revenues during the year ended December 31, 2017 and 2016, respectively, and Bruker Energy & Supercon Technologies (BEST), which represented the remainder of the Company's revenues. Within BSI, the Company is organized into three operating segments: the Bruker BioSpin Group, the Bruker CALID Group and the Bruker Nano Group. For financial reporting purposes, the Bruker BioSpin, Bruker CALID and Bruker Nano operating segments are aggregated into the BSI reportable segment because each has similar economic characteristics, production processes, service offerings, types and classes of customers, methods of distribution and regulatory environments.

        Bruker BioSpin— The Bruker BioSpin Group designs, manufactures and distributes enabling life science tools based on magnetic resonance technology. The majority of the Bruker BioSpin Group's revenues are generated by academic and government research customers. Other customers include pharmaceutical and biotechnology companies and nonprofit laboratories, as well as chemical, food and beverage, clinical and other industrial companies.

        Bruker CALID (Chemicals, Applied Markets, Life Science, In-Vitro Diagnostics, Detection)— The Bruker CALID Group designs, manufactures and distributes life science mass spectrometry and ion mobility spectrometry solutions, analytical and process analysis instruments and solutions based on infrared and Raman molecular spectroscopy technologies; and radiological/nuclear detectors for Chemical, Biological, Radiological, Nuclear and Explosive (CBRNE) detection. Customers of the Bruker CALID Group include: academic institutions and medical schools; pharmaceutical, biotechnology and diagnostics companies; contract research organizations; nonprofit or for-profit forensics laboratories; agriculture, food and beverage safety laboratories; environmental and clinical microbiology laboratories; hospitals and government departments and agencies.

        Bruker Nano— The Bruker Nano Group designs, manufactures and distributes advanced X-ray instruments; atomic force microscopy instrumentation; advanced fluorescence optical microscopy instruments; analytical tools for electron microscopes and X-ray metrology; defect-detection equipment for semiconductor process control; handheld, portable and mobile X-ray fluorescence spectrometry instruments; and spark optical emission spectroscopy systems. Customers of the Bruker Nano Group include academic institutions, governmental customers, nanotechnology companies, semiconductor companies, raw material manufacturers, industrial companies, biotechnology and pharmaceutical companies and other businesses involved in materials analysis.

        The Company's BEST reportable segment develops and manufactures superconducting and non-superconducting materials and devices for use in renewable energy, energy infrastructure, healthcare and "big science" research. The segment focuses on metallic low temperature superconductors for use in magnetic resonance imaging, nuclear magnetic resonance, fusion energy

research and other applications, as well as ceramic high temperature superconductors primarily for energy grid and magnet applications.

Note 2—Summary of Significant Accounting Policies

        The accompanying consolidated financial statements reflect the application of certain significant accounting policies as described below and elsewhere in the notes to the consolidated financial statements.

Principles of Consolidation

        The accompanying consolidated financial statements include the accounts of the Company and all majority and wholly-owned subsidiaries. All intercompany accounts and transactions have been eliminated.

Noncontrolling Interests

        Noncontrolling interests represents the minority shareholders' proportionate share of the Company's majority-owned subsidiaries. The portion of net income or net loss attributable to non-controlling interests is presented as net income attributable to noncontrolling interests in consolidated subsidiaries in the consolidated statements of income and comprehensive income, and the portion of other comprehensive income of these subsidiaries is presented in the consolidated statements of shareholders' equity.

Subsequent Events

        The Company has evaluated all subsequent events and determined that there are no material recognized or unrecognized subsequent events, or any subsequent events required to be mentioned in the footnotes to the consolidated financial statements.

Cash and Cash Equivalents

        Cash and cash equivalents primarily include cash on hand, money market funds and time deposits with original maturities of three months or less at the date of acquisition. Time deposits represent amounts on deposit in banks and temporarily invested in instruments with maturities of three months or less at the time of purchase. Certain of these investments represent deposits which are not insured by the FDIC or any other government agency. Cash equivalents are carried at cost, which approximates fair value.

Short-term Investments

        Short-term investments represent time and call deposits with original maturities of greater than three months at the date of acquisition. Short-term investments are classified as available-for-sale and are reported at fair value. There were no unrealized gains (losses) recorded as of December 31, 2017 and 2016, as cost approximates current fair value.

Restricted Cash

        In November 2016, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update (ASU) 2016-18, Statement of Cash Flows, Restricted Cash, requiring restricted cash and restricted cash equivalents to be included with cash and cash equivalents on the statement of cash flows when reconciling the beginning-of-period and end-of-period total amounts shown on the statement of cash flows. The guidance is effective for interim and annual periods beginning after December 15, 2017, with early adoption permitted. The Company adopted this standard during the first

Table of Contents

quarter of 2017. Restricted cash is now included as a component of cash, cash equivalents, and restricted cash on the Company's consolidated statement of cash flows. The Company has certain subsidiaries which are required by local governance to maintain restricted cash balances to cover future employee benefit payments. Restricted cash balances are classified as non-current unless, under the terms of the applicable agreements, the funds will be released from restrictions within one year from the balance sheet date. The current and non-current portion of restricted cash is recorded within other current assets and other long-term assets, respectively, in the accompanying consolidated balance sheets.

        The inclusion of restricted cash increased the balances of the consolidated statement of cash flows as follows:

Derivative Financial Instruments and Hedging Activities

        All derivatives, whether designated in a hedging relationship or not, are recorded on the consolidated balance sheets at fair value. The accounting for changes in fair value of a derivative instrument depends on whether it has been designated and qualifies as part of a hedging relationship and further, on the type of hedging relationship. For those derivative instruments that are designated and qualify as hedging instruments, the Company must designate the hedging instrument, based on the exposure being hedged, as a fair value hedge, cash flow hedge, foreign currency hedge or a hedge of a net investment in a foreign operation.

Fair Value of Financial Instruments

        The Company applies the following hierarchy to determine the fair value of financial instruments, which prioritizes the inputs used to measure fair value into three levels and bases the categorization within the hierarchy upon the lowest level of input that is available and significant to the fair value measurement. The levels in the hierarchy are defined as follows:

•

Level 1:  Inputs to the valuation methodology are quoted prices (unadjusted) for identical assets or liabilities in active markets.



•

Level 2:  Inputs to the valuation methodology include quoted prices for similar assets and liabilities in active markets, and inputs that are observable for the asset or liability, either directly or indirectly, for substantially the full term of the financial instrument.



•

Level 3:  Inputs to the valuation methodology are unobservable and significant to the fair value measurement.

        The valuation techniques that may be used by the Company to determine the fair value of Level 2 and Level 3 financial instruments are the market approach, the income approach and the cost approach. The market approach uses prices and other relevant information generated by market transactions involving identical or comparable assets or liabilities. The income approach uses valuation techniques to convert future amounts to a single present value based on current market expectations about those future amounts, including present value techniques, option-pricing models and the excess earnings method. The cost approach is based on the amount that would be required to replace the service capacity of an asset (replacement cost).

        The Company's financial instruments consist primarily of cash equivalents, short-term investments, restricted cash, derivative instruments consisting of forward foreign exchange contracts, commodity contracts, derivatives embedded in certain purchase and sale contracts, accounts receivable, accounts

79

Table of Contents

payable, contingent consideration and long-term debt. The carrying amounts of the Company's cash equivalents, short-term investments and restricted cash, accounts receivable, borrowings under a revolving credit agreement and accounts payable approximate fair value because of their short-term nature. Derivative assets and liabilities are measured at fair value on a recurring basis. The Company's long-term debt consists principally of a private placement arrangement entered into in 2012 with various fixed interest rates based on the maturity date and borrowings under a revolving credit agreement,

        The Company has evaluated the estimated fair value of financial instruments using available market information and management's estimates. The use of different market assumptions and/or estimation methodologies could have a significant effect on the estimated fair value amounts.

Concentration of Credit Risk

        Financial instruments that subject the Company to credit risk consist of cash, cash equivalents, short-term investments, derivative instruments, accounts receivables and restricted cash. The risk with respect to cash, cash equivalents and short-term investments is minimized by the Company's policy of investing in short-term financial instruments issued by highly-rated financial institutions. The risk with respect to derivative instruments is minimized by the Company's policy of entering into arrangements with highly-rated financial institutions. The risk with respect to accounts receivables is minimized by the creditworthiness and diversity of the Company's customers. The Company performs periodic credit evaluations of its customers' financial condition and generally requires an advanced deposit for a portion of the purchase price. Credit losses have been within management's expectations and the allowance for doubtful accounts totaled $4.7 million and $7.9 million as of December 31, 2017 and 2016, respectively. As of December 31, 2017 and 2016, no single customer represented 10% or more of the Company's accounts receivable. For the years ended December 31, 2017, 2016 and 2015, no single customer represented 10% or more of the Company's total revenue.

Inventories

        Components of inventory include raw materials, work-in-process, demonstration units and finished goods. Demonstration units include systems which are located in the Company's demonstration laboratories or installed at the sites of potential customers and are considered available for sale. Finished goods include in-transit systems that have been shipped to the Company's customers, but not yet installed and accepted by the customer. All inventories are stated at the lower of cost and net realizable value. Cost is determined principally by the first-in, first-out method for a majority of subsidiaries and by average-cost for certain other subsidiaries. The Company reduces the carrying value of its inventories for differences between cost and estimated net realizable value, taking into consideration usage in the preceding twelve months, expected demand, technological obsolescence and other information including the physical condition of demonstration inventories. The Company records a charge to cost of product revenue for the amount required to reduce the carrying value of inventory to net realizable value. Costs associated with the procurement of inventories, such as inbound freight charges and purchasing and receiving costs, are capitalized as part of inventory and are also included in the cost of product revenue line item within the consolidated statements of income and comprehensive income.

Property, Plant and Equipment

        Property, plant and equipment are stated at cost less accumulated depreciation and amortization. Major improvements are capitalized while expenditures for maintenance, repairs and minor improvements are charged to expense as incurred. When assets are retired or otherwise disposed of, the assets and related accumulated depreciation and amortization are eliminated from the accounts and any resulting gain or loss is reflected in the consolidated statements of income and comprehensive

80

---

Table of Contents

income. Depreciation and amortization are calculated on a straight-line basis over the estimated useful lives of the assets as follows:

Goodwill and Intangible Assets

        Goodwill and indefinite-lived intangible assets are not amortized, but are evaluated for impairment on an annual basis, or on an interim basis when events or changes in circumstances indicate that the carrying value may not be recoverable. In assessing the recoverability of goodwill and indefinite-lived intangible assets, the Company must make assumptions regarding the estimated future cash flows, and other factors, to determine the fair value of these assets. If these estimates or their related assumptions change in the future, the Company may be required to record impairment charges against these assets in the reporting period in which the impairment is determined.

        The Company tests goodwill for impairment at the reporting unit level, which is the operating segment or one level below an operating segment. The Company has the option of performing a qualitative assessment to determine whether further impairment testing is necessary before performing the two-step quantitative assessment. If as a result of the qualitative assessment, it is more-likely-than-not that the fair value of a reporting unit is less than its carrying amount, a quantitative impairment test will be required. Otherwise, no further testing will be required. If a quantitative impairment test is performed, the first step involves comparing the fair values of the applicable reporting units with their aggregate carrying values, including goodwill. The Company generally determines fair value of reporting units using a weighting of both the market and the income methodologies. Estimating the fair value of the reporting units requires significant judgment by management. If the carrying amount of a reporting unit exceeds the fair value of the reporting unit, the Company performs the second step of the goodwill impairment test to measure the amount of the impairment. In the second step of the goodwill impairment test the Company compares the implied fair value of the reporting unit's goodwill with the carrying value of that goodwill.

        In process research and development, or IPR&D, acquired as part of business combinations under the acquisition method represents ongoing development work associated with enhancements to existing products, as well as the development of next generation products. IPR&D is initially capitalized at fair value as an intangible asset with an indefinite life and assessed for impairment on an annual basis, or when indicators of impairment are identified. When the IPR&D project is complete, it is reclassified as a finite-lived intangible asset and is amortized over its estimated useful life. If an IPR&D project is abandoned before completion or is otherwise determined to be impaired, the value of the asset or the amount of the impairment is charged to the consolidated statements of income and comprehensive income in the period the project is abandoned or impaired.

        Intangible assets with a finite useful life are amortized on a straight-line basis over their estimated useful lives as follows:

81

---

Table of Contents

Impairment of Long-Lived Assets

        Impairment losses are recorded on long-lived assets used in operations when indicators of impairment are present and the quoted market price, if available or the estimated fair value of those assets are less than the assets' carrying value and are not recoverable. Determination of recoverability is based on an estimate of undiscounted future cash flows resulting from the use of the asset and its eventual disposition. In the event that such cash flows are not expected to be sufficient to recover the carrying amount of the assets, the assets are written-down to their fair values. Impairment losses are charged to the consolidated statements of income and comprehensive income for the difference between the fair value and carrying value of the asset.

Warranty Costs and Deferred Revenue

        The Company typically provides a one year parts and labor warranty with the purchase of equipment. The anticipated cost for this warranty is accrued upon recognition of the sale and is included as a current liability on the accompanying consolidated balance sheets. The Company's warranty reserve reflects estimated material and labor costs for potential product issues for which the Company expects to incur an obligation. The Company's estimates of anticipated rates of warranty claims and costs are primarily based on historical information. The Company assesses the adequacy of the warranty reserve on a quarterly basis and adjusts the amount as necessary. If the historical data used to calculate the adequacy of the warranty reserve is not indicative of future requirements, additional or reduced warranty reserves may be required.

        The Company also offers to its customers extended warranty and service agreements extending beyond the initial warranty for a fee. These fees are recorded as deferred revenue and recognized ratably into income over the life of the extended warranty contract or service agreement.

Income Taxes

        Deferred tax assets and liabilities are recognized for the expected future tax consequences of temporary differences between the financial statement carrying amounts and the income tax basis of assets and liabilities. A valuation allowance is applied against any net deferred tax asset if, based on the available evidence, it is more likely than not that some or all of the deferred tax assets will not be realized.

        The Company records liabilities related to uncertain tax positions in accordance with the guidance that clarifies the accounting for uncertainty in income taxes recognized in a Company's financial statements. This guidance prescribes a minimum recognition threshold and measurement attribute for the financial statement recognition and measurement of a tax position taken or expected to be taken in a tax return. The Company includes accrued interest and penalties related to unrecognized tax benefits and income tax liabilities, when applicable, in income tax expense.

Customer Advances

        The Company typically requires an advance deposit under the terms and conditions of contracts with customers. These deposits are recorded as a current or long-term liability until revenue is recognized on the specific contract in accordance with the Company's revenue recognition policy.

Revenue Recognition

        The Company recognizes revenue from systems sales when persuasive evidence of an arrangement exists, the price is fixed or determinable, title and risk of loss has been transferred to the customer and collectability of the resulting receivable is reasonably assured. Title and risk of loss generally transfers upon shipment, or for certain systems, based upon customer acceptance for a system that has been

82

---

Table of Contents

delivered and installed at a customer facility. For systems that include customer-specific acceptance criteria, the Company is required to assess when it can demonstrate the acceptance criteria has been met, which generally is upon successful factory acceptance testing or customer acceptance and evidence of installation.

        When products are sold through an independent distributor or a strategic distribution partner who assumes responsibility for installation, the Company recognizes the system sale when the product has been shipped and title and risk of loss have been transferred to the distributor. The Company's distributors do not have price protection rights or rights of return; however, the Company's products are typically warranted to be free from defect for a period of one year. Revenue is deferred until cash is received when collectability is not reasonably assured or when the price is not fixed or determinable.

        For transactions that include multiple elements, arrangement consideration is allocated to each element using the fair value hierarchy as required by ASU No. 2009-13. The Company limits the amount of revenue recognized for delivered elements to the amount that is not contingent on the future delivery of products or services, future performance obligations, or subject to customer-specific return or refund privileges.

        The Company determines the fair value of its products and services based upon vendor specific objective evidence ("VSOE"). The Company determines VSOE based on its normal selling pricing and discounting practices for the specific product or service when sold on a stand-alone basis. In determining VSOE, the Company's policy requires a substantial majority of selling prices for a product or service to be within a reasonably narrow range. The Company also considers the class of customer, method of distribution and the geographies into which products and services are being sold when determining VSOE.

        If VSOE cannot be established, the Company attempts to establish the selling price based on third-party evidence ("TPE"). VSOE cannot be established in instances where a product or service has not been sold separately, stand-alone sales are too infrequent or product pricing is not within a sufficiently narrow range. TPE is determined based on competitor prices for similar deliverables when sold separately.

        When the Company cannot determine VSOE or TPE, it uses estimated selling price ("ESP") in its allocation of arrangement consideration. The objective of ESP is to determine the price at which the Company would typically transact a stand-alone sale of the product or service. ESP is determined by considering a number of factors including the Company's pricing policies, internal costs and gross profit objectives, method of distribution, market research and information, recent technological trends, competitive landscape and geographies. The Company analyzes the selling prices used in its allocation of arrangement consideration, at a minimum, on an annual basis. Selling prices will be analyzed more frequently if a significant change in the Company's business or other factors necessitate more frequent analysis or if the Company experiences significant variances in its selling prices.

        Revenue from accessories and parts is generally recognized based on shipping terms. Service revenue is recognized as the services are performed or ratably over the contractual obligation and includes maintenance contracts, extended warranty, training, application support and on-demand services.

        The Company also has contracts for which it applies the percentage-of-completion model and completed contract model of revenue recognition. Application of the percentage-of-completion method requires the Company to make reasonable estimates of the extent of progress toward completion of the contract and the total costs the Company will incur under the contract and losses are recorded immediately when we estimate that contracts will ultimately result in a loss. Changes in the estimates could affect the timing of revenue recognition.

83

Table of Contents

        Other revenues are primarily comprised of development arrangements recognized on a cost-plus-fixed-fee basis and licensing arrangements recognized ratably over the term of the related contracts.

Shipping and Handling Costs

        The Company includes costs incurred in connection with shipping and handling of products within selling, general and administrative expenses in the accompanying consolidated statements of income and comprehensive income. Shipping and handling costs were $23.2 million, $21.3 million and $20.6 million in the years ended December 31, 2017, 2016 and 2015, respectively. Amounts billed to customers in connection with these costs are included in total revenues.

Research and Development

        The Company commits substantial capital and resources to internal and collaborative research and development projects in order to provide innovative products and solutions to their customers. The Company conducts research primarily to enhance system performance and improve the reliability of existing products, and to develop revolutionary new products and solutions. Research and development costs are expensed as incurred and include salaries, wages and other personnel related costs, material costs and depreciation, consulting costs and facility costs.

Capitalized Software

        Purchased software is capitalized at cost and is amortized over the estimated useful life, which is generally three years. Software developed for use in the Company's products is expensed as incurred to research and development expense until technological feasibility is achieved. Subsequent to the achievement of technological feasibility, amounts are capitalizable; however, to date such amounts have not been material.

Advertising

        The Company expenses advertising costs as incurred. Advertising expenses were $14.0 million, $12.7 million and $12.9 million during the years ended December 31, 2017, 2016 and 2015, respectively.

Stock-Based Compensation

        The Company recognizes stock-based compensation expense in the consolidated statements of income and comprehensive income based on the fair value of the share-based award at the grant date. The Company's primary types of share-based compensation are stock options, restricted stock awards and restricted stock units. The Company recorded stock-based compensation expense for the years ended December 31, 2017, 2016 and 2015, as follows (in millions):

84

---

Table of Contents

        Compensation expense is amortized on a straight-line basis over the underlying vesting terms of the share-based award. Stock options to purchase the Company's common stock are periodically awarded to executive officers and other employees of the Company subject to a vesting period of three to four years. The fair value of each option award is estimated on the date of grant using the Black-Scholes option-pricing model. Assumptions regarding volatility, expected term, dividend yield and risk-free interest rates are required for the Black-Scholes model and are presented in the table below:

        Risk-free interest rates are based on the yield on zero-coupon U.S. Treasury securities for a period that is commensurate with the expected life assumption. Expected life is determined through a calculation based on historical data and the Company believes that this is the best estimate of the expected term of a new option. Expected volatility is based on a number of factors, but the Company currently believes that the exclusive use of its historical volatility results in the best estimate of the expectations of future volatility over the expected term. The expected dividend yield was included in the option pricing formula beginning in February of 2016 as the Company adopted a dividend policy. In addition, the Company utilizes an estimated forfeiture rate when calculating the stock-based compensation expense for the period. The Company has applied estimated forfeiture rates derived from an analysis of historical data of 6.7%, 6.2% and 5.8% for the years ended December 31, 2017, 2016 and 2015, respectively, in determining the expense recorded in the accompanying consolidated statements of income and comprehensive income.

        Starting in 2017, members of the Company's Board of Directors receive an annual award of restricted stock units which vest over a one year service period.

Earnings Per Share

        Net income per common share attributable to Bruker Corporation shareholders is calculated by dividing net income attributable to Bruker Corporation by the weighted-average shares outstanding during the period. The diluted net income per share computation includes the effect of shares which would be issuable upon the exercise of outstanding stock options and the vesting of restricted stock, reduced by the number of shares which are assumed to be purchased by the Company under the treasury stock method.

Table of Contents

        The following table sets forth the computation of basic and diluted weighted average shares outstanding for the years ended December 31, (in millions, except per share data):

        Stock options and restricted stock units to purchase approximately 0.3 million shares, 0.6 million shares and 1.3 million shares were excluded from the computation of diluted earnings per share for the years ended December 31, 2017, 2016 and 2015, respectively, because their effect would have been anti-dilutive.

Post Retirement Benefit Plans

        The Company recognizes the over-funded or under-funded status of defined benefit pension and other postretirement defined benefit plans as an asset or liability, respectively, in its consolidated balance sheets and recognizes changes in the funded status in the year in which the changes occur through other comprehensive income.

Other Comprehensive Income (Loss)

        Other comprehensive income (loss) refers to revenues, expenses, gains and losses that are excluded from net income as these amounts are recorded directly as an adjustment to shareholders' equity, net of tax. The Company's other comprehensive income (loss) was composed of foreign currency translation adjustments and pension liability adjustments.

Foreign Currency Translation

        Assets and liabilities of the Company's foreign subsidiaries, where the functional currency is the local currency, are translated into U.S. Dollars using year-end exchange rates, or historical rates, as appropriate. Revenues and expenses of foreign subsidiaries are translated at the average exchange rates in effect during the year. Adjustments resulting from financial statement translations are included as a separate component of shareholders' equity. Gains and losses resulting from translation of foreign currency monetary transactions are reported in interest and other income (expense), net in the consolidated statements of income and comprehensive income for all periods presented. The Company has certain intercompany foreign currency transactions that are deemed to be of a long-term investment nature. Exchange adjustments related to those transactions are made directly to a separate component of shareholders' equity.

Risk and Uncertainties

        The Company is subject to risks common to its industry including, but not limited to, global economic conditions, rapid technological change, government and academic funding levels, changes in

Table of Contents

commodity prices, spending patterns from its customers, protection of its intellectual property, availability of key raw materials and components, compliance with existing and future regulation by government agencies and fluctuations in foreign currency exchange rates.

Loss Contingencies

        Loss contingency provisions are recorded if the potential loss from any claim, asserted or unasserted, or legal proceeding related to patents, products and other matters, is considered probable and the amount can be reasonably estimated or a range of loss can be determined. These accruals represent management's best estimate of probable loss. Disclosure is provided when it is reasonably possible that a loss will be incurred or when it is reasonably possible that the amount of a loss will exceed the recorded provision.

Use of Estimates

        The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and reported amounts of revenues and expenses during the reporting period.

        Significant estimates and judgments made by management in preparing these financial statements include revenue recognition, allowances for doubtful accounts, write-downs for excess and obsolete inventory, estimated fair values used to record impairment charges related to intangible assets, goodwill, and other long-lived assets, amortization periods, expected future cash flows used to evaluate the recoverability of long-lived assets, stock-based compensation expense, warranty allowances, restructuring and other related charges, contingent liabilities and the recoverability of the Company's net deferred tax assets.

        Although the Company regularly reassesses the assumptions underlying these estimates, actual results could differ materially from these estimates. Changes in estimates are recorded in the period in which they become known. The Company bases its estimates on historical experience and various other assumptions that it believes to be reasonable under the circumstances. Actual results may differ from management's estimates if these results differ from historical experience or other assumptions prove not to be substantially accurate, even if such assumptions were reasonable when made.

Note 4—Fair Value of Financial Instruments

        The Company measures the following financial assets and liabilities at fair value on a recurring basis. The following tables set forth the Company's financial instruments and presents them within the

Table of Contents

fair value hierarchy using the lowest level of input that is significant to the fair value measurement at December 31, 2017 and 2016 (in millions):

 

        Derivative financial instruments are classified within level 2 because there is not an active market for each derivative contract. However, the inputs used to calculate the value of the instruments are obtained from active markets.

        The fair value of the long-term fixed interest rate debt, which has been classified as Level 2, was $231.3 million and $253.3 million at December 31, 2017 and 2016, respectively, based on market and observable sources with similar maturity dates.

        The Company measures certain assets and liabilities at fair value with changes in fair value recognized in earnings. Fair value treatment may be elected either upon initial recognition of an eligible asset or liability or, for an existing asset or liability, if an event triggers a new basis of accounting. The Company did not elect to remeasure any of its existing financial assets or liabilities during the years ended December 31, 2017 and 2016.

        Excluded from the table above are cash equivalents, restricted cash and short-term investments as the cost approximates current fair value. The Company has a program to enter into time deposits and call deposit and money market funds. The time and call deposits have varying maturity dates ranging from one to twelve month for which the Company has the ability to redeem the invested amounts over

Table of Contents

a period of 31 to 95 days. The Company has classified these investments within cash and cash equivalents or short-term investments within the consolidated balance sheets based on call and maturity dates. There are no cash equivalents, $4.0 million and $3.4 million of restricted cash and $114.2 million and $157.9 million of short-term investments outstanding as of December 31, 2017 and 2016, respectively. On a quarterly basis, the Company reviews its short-term investments to determine if there have been any events that could create an impairment. None were noted for the years ended December 31, 2017 and 2016.

        As part of certain acquisitions in 2017, 2016, and 2015, the Company recorded contingent consideration liabilities that have been classified as Level 3 in the fair value hierarchy. The contingent consideration represents the estimated fair value of future payments to the former shareholders of applicable acquired companies based on achieving annual revenue and gross margin targets in certain years as specified in the purchase and sale agreements. The Company initially values the contingent considerations by using a Monte Carlo simulation or an income approach method. The Monte Carlo method models future revenue and costs of goods sold projections and discounts the average results to present value. The income approach method involves calculating the earnout payment based on the forecasted cash flows, adjusting the future earnout payment for the risk of reaching the projected financials, and then discounting the future payments to present value by the counterparty risk. The counterparty risk considers the risk of the buyer having the cash to make the earnout payments and is commensurate with the cost of debt over an appropriate term.

        Changes to the fair value of the contingent consideration recognized in earnings for the years ended December 31, 2017 and December 31, 2016 were $2.3 million and $6.9 million, respectively, These amounts were recorded to other charges, net in the consolidated statements of income and comprehensive income for increases of contingent consideration representing expected achievement of financial targets. The following table sets forth the changes in contingent consideration liabilities for the years ended December 31, 2017 and 2016 (in millions):

        The allowance for doubtful accounts is management's estimate of credit losses in the accounts receivable. The allowance for doubtful accounts is based on a number of factors, including an evaluation of customer credit worthiness, the age of the outstanding receivable, economic trends and historical experience. The allowance for doubtful accounts is reviewed on a quarterly basis and changes in estimates are reflected in the period in which they become known. The Company records account balances against the allowance after all means of collection have been exhausted and the potential for recovery is considered remote. Provisions for doubtful accounts are recorded in selling, general and administrative expenses in the accompanying consolidated statements of income and comprehensive income.

        The following is a summary of the activity in the Company's allowance for doubtful accounts at December 31, (in millions):

Note 6—Inventories

        Inventories consisted of the following at December 31, (in millions):

        Finished goods include in-transit systems that have been shipped to the Company's customers but not yet installed and accepted by the customer. As of December 31, 2017 and 2016, inventory-in-transit was $41.4 million and $37.5 million, respectively.

        In July 2015, the FASB issued ASU No. 2015-11, Simplifying the Measurement of Inventory. This guidance eliminates the measurement of inventory at market value, and inventory is now measured at the lower of cost and net realizable value. The ASU defines net realizable value as the estimated selling prices in the ordinary course of business, less reasonably predictable costs of completion, disposal, and transportation. No other changes were made to the current guidance on inventory measurement. The Company adopted ASU No. 2015-11 on a prospective basis in the first quarter of 2017.

The Company performed its annual impairment evaluation using a qualitative approach at December 31, 2017 and 2016 and a quantitative approach at December 31, 2015 and concluded it was more likely than not that goodwill has not been impaired. Based on the most recent quantitative analysis the fair values of each of our reporting units was significantly greater than their carrying amounts and, therefore, no additional impairment was required.

        The Company's debt obligations consist of the following as of December 31, (in millions):

Credit Agreements

        On October 27, 2015, the Company entered into a new revolving credit agreement, referred to as the 2015 Credit Agreement. The 2015 Credit Agreement provides a maximum commitment on the Company's revolving credit line of $500 million and a maturity date of October 2020. Borrowings under the revolving credit line of the 2015 Credit Agreement accrue interest, at the Company's option, at either (a) the greatest of (i) the prime rate, (ii) the federal funds rate plus 0.50% and (iii) adjusted LIBOR plus 1.00%, plus margins ranging from 0.00% to 0.30% or (b) LIBOR, plus margins ranging from 0.90% to 1.30%. There is also a facility fee ranging from 0.10% to 0.20%.

        Borrowings under the 2015 Credit Agreement are secured by guarantees from certain material subsidiaries, as defined in the 2015 Credit Agreement. The 2015 Credit Agreement also requires the Company to maintain certain financial ratios related to maximum leverage and minimum interest coverage (as defined in the 2015 Credit Agreement). Specifically, the Company's leverage ratio cannot exceed 3.5 and the Company's interest coverage ratio cannot be less than 2.5. In addition to the financial ratios, the 2015 Credit Agreement contains negative covenants, including among others, restrictions on liens, indebtedness of the Company and its subsidiaries, asset sales, dividends and transactions with affiliates. Failure to comply with any of these restrictions or covenants may result in an event of default on the 2015 Credit Agreement, which could permit acceleration of the debt and require the Company to prepay the debt before its scheduled due date.

Table of Contents

        As of December 31, 2017, the Company was in compliance with the covenants of the 2015 Credit Agreement. The Company's leverage ratio (as defined in the 2015 Credit Agreement) was 1.32 and interest coverage ratio (as defined in the 2015 Credit Agreement) was 15.5.

        The following is a summary of the maximum commitments and the net amounts available to the Company under the 2015 Credit Agreement and other lines of credit with various financial institutions located primarily in Germany and Switzerland that are unsecured and typically due upon demand with interest payable monthly, at December 31, 2017 (in millions):

Note Purchase Agreement

        In January 2012, the Company entered into a note purchase agreement, referred to as the Note Purchase Agreement, with a group of accredited institutional investors. Pursuant to the Note Purchase Agreement, the Company issued and sold $240.0 million of senior notes, referred to as the Senior Notes, which consist of the following:

•

$20 million 3.16% Series 2012A Senior Notes, Tranche A, due January 18, 2017;

•

$100 million 4.46% Series 2012A Senior Notes, Tranche D, due January 18, 2024.

        On January 18, 2017, the outstanding $20.0 million principal amount of Tranche A of the Senior Notes was repaid in accordance with the terms of the Note Purchase Agreement.

        Under the terms of the Note Purchase Agreement, the Company may issue and sell additional senior notes up to an aggregate principal amount of $600 million, subject to certain conditions. Interest on the Senior Notes is payable semi-annually on January 18 and July 18 of each year. The Senior Notes are unsecured obligations of the Company and are fully and unconditionally guaranteed by certain of the Company's direct and indirect subsidiaries. The Senior Notes rank pari passu in right of repayment with the Company's other senior unsecured indebtedness. The Company may prepay some or all of the Senior Notes at any time in an amount not less than 10% of the original aggregate principal amount of the Senior Notes to be prepaid, at a price equal to the sum of (a) 100% of the principal amount thereof, plus accrued and unpaid interest, and (b) the applicable make-whole amount, upon not less than 30 and no more than 60 days written notice to the holders of the Senior Notes. In the event of a change in control of the Company, as defined in the Note Purchase Agreement, the Company may be required to prepay the Notes at a price equal to 100% of the principal amount thereof, plus accrued and unpaid interest.

        The Note Purchase Agreement contains affirmative covenants, including, without limitation, maintenance of corporate existence, compliance with laws, maintenance of insurance and properties, payment of taxes, addition of subsidiary guarantors and furnishing notices and other information. The Note Purchase Agreement also contains certain restrictive covenants that restrict the Company's ability to, among other things, incur liens, transfer or sell assets, engage in certain mergers and consolidations and enter into transactions with affiliates. The Note Purchase Agreement also includes customary

representations and warranties and events of default. In the case of an event of default arising from specified events of bankruptcy or insolvency, all outstanding Senior Notes will become due and payable immediately without further action or notice. In the case of payment events of defaults, any holder of Senior Notes affected thereby may declare all Senior Notes held by it due and payable immediately. In the case of any other event of default, a majority of the holders of the Senior Notes may declare all the Senior Notes to be due and payable immediately. Pursuant to the Note Purchase Agreement, so long as any Senior Notes are outstanding the Company will not permit (i) its leverage ratio, as determined pursuant to the Note Purchase Agreement, as of the end of any fiscal quarter to exceed 3.50 to 1.00, (ii) its interest coverage ratio as determined pursuant to the Note Purchase Agreement as of the end of any fiscal quarter for any period of four consecutive fiscal quarters to be less than 2.50 to 1 or (iii) priority debt at any time to exceed 25% of consolidated net worth, as determined pursuant to the Note Purchase Agreement.

        As of December 31, 2017, the Company was in compliance with the covenants of the Note Purchase Agreement. The Company's leverage ratio (as defined in the Note Purchase Agreement) was 1.32 and interest coverage ratio (as defined in the Note Purchase Agreement) was 15.5.

        Annual maturities of debt outstanding, less deferred financing cost amortization, at December 31, 2017 are as follows (in millions):

        Interest expense for the years ended December 31, 2017, 2016 and 2015, was $15.4 million, $13.2 million and $13.0 million, respectively.

        In April 2015, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update (ASU) 2015-03, Simplifying the Presentation of Debt Issuance Costs, which amended the existing guidance to require that debt issuance costs be presented in the consolidated balance sheet as a reduction from the carrying amount of the related debt liability instead of as an other asset. The Company adopted ASU 2015-03 on a retrospective basis for the year ended December 31, 2016. As of December 31, 2017 and 2016, there were $0.7 million and $0.8 million, respectively, in debt issuance costs recorded as a reduction in the carrying value of the related debt liability under the Note Purchase Agreement. The $0.7 million in debt issuance costs as of December 31, 2017 will be amortized over the remaining term of the Note Purchase Agreement. The Company also adopted ASU No. 2015-15, Presentation and Subsequent Measurement of Debt Issuance Costs Associated with Line-of-Credit Arrangements, and elected not to reclassify the debt issuance costs related to line-of-credit arrangements for the 2015 Credit Agreement.

Note 11—Derivative Instruments and Hedging Activities

Interest Rate Risks

        The Company's exposure to interest rate risk relates primarily to outstanding variable rate debt and adverse movements in the related short-term market rates. The most significant component of the Company's interest rate risk relates to amounts outstanding under the 2015 Credit Agreement, which totaled $195.0 million at December 31, 2017. The Company currently has approximately equal levels of fixed and floating rate debt, which limits the exposure to adverse movements in interest rates.

Foreign Exchange Rate Risk Management

        The Company generates a substantial portion of its revenues and expenses in international markets, principally Germany and other countries in the European Union and Switzerland, which subjects its operations to the exposure of foreign rate fluctuations. The impact of foreign exchange rate movement can be positive or negative in any period. The Company periodically enters into foreign currency contracts in order to minimize the volatility that fluctuations in currency translation have on its monetary transactions. Under these arrangements, the Company typically agrees to purchase a fixed amount of a foreign currency in exchange for a fixed amount of U.S. Dollars or other currencies on specified dates with maturities of less than twelve months. These transactions do not qualify for hedge accounting and, accordingly, the instrument is recorded at fair value with the corresponding gains and losses recorded in the consolidated statements of income and comprehensive income. The Company had the following notional amounts outstanding under foreign currency contracts at December 31, (in millions):

        In addition, the Company periodically enters into purchase and sales contracts denominated in currencies other than the functional currency of the parties to the transaction. The Company accounts for these transactions separately valuing the "embedded derivative" component of these contracts. The contracts, denominated in currencies other than the functional currency of the transacting parties, amounted to $98.3 million for the delivery of products and $3.6 million for the purchase of products at December 31, 2017 and $120.7 million for the delivery of products and $2.3 million for the purchase of products at December 31, 2016. The changes in the fair value of these embedded derivatives are recorded in interest and other income (expense), net in the consolidated statements of income and comprehensive income.

Commodity Price Risk Management

        The Company has an arrangement with a customer under which it has a firm commitment to deliver copper based superconductors at a fixed price. In order to minimize the volatility that fluctuations in the price of copper have on the Company's sales of these commodities, the Company enters into commodity hedge contracts. At December 31, 2017 and 2016, the Company has fixed price commodity contracts with notional amounts aggregating $3.0 million and $2.7 million, respectively. The changes in the fair value of these commodity contracts are recorded in interest and other income (expense), net in the consolidated statements of income and comprehensive income.

Note 12—Income Taxes

        On December 22, 2017 (Enactment Date), the President of the United States signed tax reform legislation (2017 Tax Act), which enacted a wide range of changes to the U.S. corporate income tax system, many of which differ significantly from the provisions of the previous U.S. tax law. The 2017 Tax Act contains several key provisions including, among other things:

•

A one-time tax on the mandatory deemed repatriation of post-1986 untaxed foreign earnings and profits (E&P), referred to as the "toll charge";



•

A reduction in the corporate tax rate from 35.0% to 21.0% for the tax years beginning after December 31, 2017;



•

The introduction of a new U.S. tax on certain off-shore earnings referred to as the "Global Intangible Low-Taxed Income" (GILTI) at an effective tax rate of 10.5% for tax years beginning after December 31, 2017 (increasing to 13.125% for tax years beginning after December 31, 2025) with a partial offset by foreign tax credits; and



•

The introduction of a territorial tax system beginning in 2018 by providing a 100% dividends received deduction on certain qualified dividends from foreign subsidiaries.

        Also on December 22, 2017, the Securities and Exchange Commission (SEC) issued Staff Accounting Bulletin (SAB) No. 118, which provides companies with additional guidance on how to implement the provisions of the 2017 Tax Act in their financial statements. The guidance provides for a measurement period, up to one year from the Enactment Date, in which provisional amounts may be adjusted when additional information is obtained, prepared or analyzed about facts and circumstances that existed as of the Enactment Date, if known, which would have impacted the amounts that were initially recorded by the Company.

        The Company has not yet completed the assessment of the tax effects associated with the enactment of the 2017 Tax Act; however, a reasonable estimate has been made of the effects on the existing deferred tax balances and the one-time transition tax. Changes in the tax rates and laws are accounted for in the period of enactment. Therefore, during the fourth quarter of 2017, the Company recorded an incremental income tax provision of $68.9 million, which is primarily comprised of the following:

•

An estimated income tax provision of $55.0 million for the federal and state impacts of the one-time deemed repatriation of pre-2018 E&P. In accordance with the 2017 Tax Act, the federal portion of the toll charge liability may be paid over eight years. Such liability can be reduced by certain credits. Accordingly, we have recorded $30.6 million and $2.7 million in long-term income tax liabilities and accrued income taxes (current), respectively, as of December 31, 2017



•

An estimated net income tax benefit of $1.4 million, for the remeasurement of our deferred tax assets and liabilities at the newly enacted tax rate of 21%; and



•

As a result of the 2017 Tax Act and our expectations about distributing certain cash balances from its foreign subsidiaries to the United States, we also recorded estimated income tax provisions for estimated state income taxes and foreign withholding taxes of $12.5 million.

        The net charge of $68.9 million recorded was based on currently available information and interpretations of applying the provisions of the 2017 Tax Act as of the time of filing this Annual Report on Form 10-K. The Company expects to finalize these provisional estimates before the end of 2018 after completing the review and analysis, including reviews and analysis of any interpretations issued during this measurement period.

        The Company is still evaluating the GILTI provisions of the 2017 Tax Act and its impact, if any, to the consolidated financial statements as of December 31, 2017. Companies are allowed to adopt an accounting policy to either recognize deferred taxes for GILTI or treat such as a tax cost in the year incurred. The Company has not yet determined the accounting policy because determining the impact of the GILTI provisions requires analysis of the existing legal entity structure, the reversal of U.S. GAAP and U.S. tax basis differences in the assets and liabilities of foreign subsidiaries, and the ability to offset any tax with foreign tax credits. As such, the Company did not record a deferred income tax expense or benefit related to the GILTI provisions of the 2017 Tax Act in the consolidated statement of income for the year ended December 31, 2017. This will also be finalized during the measurement period.

        The Company recorded a provisional amount for the toll charge, which represents its reasonable estimate of the liability due for the mandatory deemed repatriation of its post-1986 untaxed foreign E&P. Determining the provisional toll charge liability required a significant effort based on a number of factors including:

•

Analyzing the accumulated untaxed foreign E&P since 1986 including historical practices and assertions made in determining such;



•

Determining the composition, including intercompany receivables and payables of specified foreign corporations, of our post-1986 untaxed foreign E&P that is held in cash or liquid assets and other assets at several measurement dates. This is required because a different tax rate is applied to each when determining the toll charge liability; and



•

Assessing the potential impact of existing uncertain tax positions in determining our accumulated undistributed E&P.

        Due to the timing of the Enactment Date, the Company had limited time to understand the 2017 Tax Act and its various interpretations, to assess how to apply the new tax law to the specific facts and

103

Table of Contents

circumstances of the Company and to determine the toll charge. As such the amounts recorded for the toll charge are provisional.

        The actual results of the implementation of the 2017 Tax Act may materially differ from the Company's current estimate due to, among other things, further guidance that may be issued by U.S. tax authorities or regulatory bodies including the SEC and the FASB to interpret the 2017 Tax Act. The Company will continue to analyze the 2017 Tax Act and any additional guidance that may be issued and finalize the full effects of applying the new legislation in the measurement period.

        The Company uses the liability method to account for income taxes. Under this method, deferred income taxes are recognized for the future tax consequences of differences between the tax and financial accounting bases of assets and liabilities at each reporting period. Deferred income taxes are

105

Table of Contents

based on enacted tax laws and statutory tax rates applicable to the period in which these differences are expected to affect taxable income. A valuation allowance is established when necessary to reduce deferred tax assets to the expected realizable amounts.

        The Company can only recognize a deferred tax asset to the extent this it is "more likely than not" that these assets will be realized. Judgments around realizability depend on the availability and weight of both positive and negative evidence. Changes in the valuation allowance for deferred tax assets during the years ended December 31, 2017, 2016 and 2015 were as follows:

        The decreases related primarily to the realizability of foreign net operating and capital losses based on future taxable income.

        As of December 31, 2017, the Company has approximately $23.2 million net operating loss carryforwards available to reduce state taxable income. The Company also has approximately $77.4 million of German Trade Tax and Corporate Income Tax net operating losses that are carried forward indefinitely. Additionally, the Company has $13.9 million of other foreign net operating losses that are expected to expire at various times beginning in 2018. The Company also has state research and development tax credits of $7.5 million. Utilization of these credits and state net operating losses may be subject to annual limitations due to the ownership percentage change limitations provided by the Internal Revenue Code Section 382 and similar state provisions. In the event of a deemed change in control under Internal Revenue Code Section 382, an annual limitation on the utilization of net operating losses and credits may result in the expiration of all or a portion of the net operating loss and credit carryforwards.

        The Company reflects certain statutory reserves in its tabular reconciliation of unrecognized tax benefits. Effective for the year ended December 31, 2013 and thereafter, these unrecognized tax benefits are presented as a reduction of the associated net deferred tax assets.

        At December 31, 2017 and in accordance with the 2017 Tax Act, the Company recorded state and foreign withholding taxes on the cash and liquid assets portion of the unremitted earnings and profits (E&P) of foreign subsidiaries expected to be repatriated from its foreign subsidiaries to the United States. The Company continues to be indefinitely reinvested amounting to $740.0 million of non-cash E&P that is related to the 2017 Tax Act deemed repatriation. If this E&P is ultimately distributed to the United States in the form of dividends or otherwise the Company would likely be subject to additional withholding tax. The Company will continue to evaluate its assertions on the cumulative historical outside basis differences in its foreign subsidiaries as of December 31, 2017. The Company expects to finalize its analysis and accounting related to the toll charge and any remaining outside basis differences in its foreign subsidiaries during the measurement period. The Company estimates the amount of unrecognized deferred withholding taxes on the undistributed E&P to be approximately $27 million at December 31, 2017.

        The Company had gross unrecognized tax benefits, excluding interest, of approximately $4.4 million as of December 31, 2017, that if recognized, would reduce the Company's effective tax rate. In the next twelve months it is reasonably possible that the Company will reduce its unrecognized

106

Table of Contents

tax benefits by $0.8 million due to the expiration of statutes of limitations and favorable settlement with taxing authorities which would reduce the Company's effective tax rate. A tabular reconciliation of the beginning and ending amount of unrecognized tax benefits is as follows (in millions):

        The Company's policy is to include accrued interest and penalties related to unrecognized tax benefits and income tax liabilities, when applicable, in income tax expense. As of December 31, 2017 and 2016, the Company had approximately $0.2 million and $0.5 million, respectively, of accrued interest and penalties related to uncertain tax positions included in other long-term liabilities in the consolidated balance sheets. The Company recorded a benefit of $0.3 million and $1.8 million for penalties and interest related to unrecognized tax benefits in the provision for income taxes during the year ended December 31, 2017 and December 31, 2016, respectively.

        The Company files tax returns in the United States, which includes federal, state and local jurisdictions, and many foreign jurisdictions with varying statutes of limitations. The Company considers Germany, the United States and Switzerland to be its significant tax jurisdictions. The majority of the Company's earnings are derived in Germany and Switzerland. Accounting for the various federal and local taxing authorities, the statutory rates for 2017 were approximately 30.0% and 20.0% for Germany and Switzerland, respectively. The mix of earnings in those two jurisdictions resulted in a reduction of 7.8% from the U.S. statutory rate of 35.0% in 2017. The Company has not been a party to any tax holiday agreements. The tax years 2013 to 2016 are open to examination in Germany and Switzerland. In the third quarter of 2015, the Company settled tax audits in Germany and Italy. In 2016, the Company settled tax audits in Germany and Switzerland. The settlements were immaterial to the consolidated financial statements. Tax years 2011 to 2016 remain open for examination in the United States.

Note 13—Post Retirement Benefit Plans

Defined Contribution Plans

        The Company sponsors various defined contribution plans that cover certain domestic and international employees. The Company may make contributions to these plans at its discretion. The Company contributed $6.4 million, $6.0 million and $6.5 million to such plans in the years ended December 31, 2017, 2016 and 2015, respectively.

Defined Benefit Plans

        Substantially all of the Company's employees in Switzerland, France and Japan, as well as certain employees in Germany, are covered by Company-sponsored defined benefit pension plans. Retirement benefits are generally earned based on years of service and compensation during active employment. Eligibility is generally determined in accordance with local statutory requirements, however, the level of benefits and terms of vesting varies among plans.

        The components of net periodic benefit costs for the years ended December 31, 2017, 2016 and 2015 were as follows (in millions):

        The net periodic benefit costs for the year ended December 31, 2015 includes a one-time, non-cash settlement loss of $10.2 million as the Company outsourced its pension plan in Switzerland to an outside insurance provider, transferred certain plan assets and pension obligations for retirees and other certain members of the population, made certain plan design changes and re-measured the liability.

        The Company measures its benefit obligation and the fair value of plan assets as of December 31st each year. The changes in benefit obligations and plan assets under the defined benefit pension plans, projected benefit obligation and funded status of the plans were as follows at December 31, (in millions):

Table of Contents

        The accumulated benefit obligation for the defined benefit pension plans is $217.2 million and $199.9 million at December 31, 2017 and 2016, respectively. All defined benefit pension plans have an accumulated benefit obligation and projected benefit obligation in excess of plan assets at December 31, 2017 and 2016.

        The following amounts were recognized in the accompanying consolidated balance sheets for the Company's defined benefit plans at December 31, (in millions):

        The following pre-tax amounts were recognized in accumulated other comprehensive income for the Company's defined benefit plans at December 31, (in millions):

        The amount in accumulated other comprehensive income at December 31, 2017 expected to be recognized as amortization of net loss within net periodic benefit cost in 2018 is $3.9 million.

        For the defined benefit pension plans, the Company uses a corridor approach to amortize actuarial gains and losses. Under this approach, net actuarial gains or losses in excess of ten percent of the larger of the projected benefit obligation or the fair value of plan assets are amortized over the average remaining service of active participants who are expected to receive benefits under the plans.

        The range of assumptions used for defined benefit pension plans reflects the different economic environments within the various countries. The range of assumptions used to determine the projected benefit obligations for the years ended December 31, are as follows:

        To determine the expected long-term rate of return on pension plan assets, the Company considers current asset allocations, as well as historical and expected returns on various asset categories of plan assets. For the defined benefit pension plans, the Company applies the expected rate of return to a market-related value of assets, which stabilizes variability in assets to which the expected return is applied.

Note 14—Commitments and Contingencies

        In accordance with ASC Topic 450, Contingencies, the Company accrues anticipated costs of settlement, damages, or other costs to the extent specific losses are probable and estimable.

Litigation and Related Contingencies

        Lawsuits, claims and proceedings of a nature considered normal to its businesses may be pending from time to time against the Company. Third parties might allege that the Company or its collaborators are infringing their patent rights or that the Company is otherwise violating their intellectual property rights. Loss contingency provisions are recorded if the potential loss from any claim, asserted or unasserted, or legal proceeding is considered probable and the amount can be reasonably estimated or a range of loss can be determined. These accruals represent management's best estimate of probable loss. Disclosure also is provided when it is reasonably possible that a loss will be incurred or when it is reasonably possible that the amount of a loss will exceed the recorded provision. The Company believes the outcome of pending proceedings, individually and in the aggregate, will not have a material impact on the Company's financial statements. As of December 31, 2017 and 2016, no material accruals have been recorded for potential contingencies.

Governmental Investigations

        The Company is subject from time to time to investigations by U.S. or foreign governmental agencies, from which civil, criminal or administrative proceedings could result.

        On October 19, 2017, the Company received a notice of investigation and subpoena to produce documents from the Division of Enforcement of the SEC. The subpoena seeks information related to an employee terminated as part of a restructuring and certain matters involving the Company's policies and accounting practices related to revenue recognition and restructuring activities, as well as related financial reporting, disclosure and compliance matters, since January 1, 2013. The subpoena also seeks information concerning, among other things, the Company's previously identified material weakness in internal controls over the accounting for income taxes, related financial reporting matters and certain payments for non-employee travel expenses. The Company is producing documents in response to the subpoena and intends to continue to cooperate fully with the SEC's investigation. At this time, the Company is unable to predict the duration, scope or outcome of this investigation.

        The Korea Fair Trade Commission ("KFTC") has conducted an investigation into improper bidding by Bruker Korea Co., Ltd. and several other companies in connection with bids for sales of X-ray systems in 2010 and 2012. Three of the bids under investigation involved Bruker Korea. The Company cooperated fully with the KFTC regarding this matter. In September 2016, the KFTC fined Bruker Korea approximately $15,000 and referred the matter to the Korean Public Prosecutor's Office ("PPO") for criminal prosecution. On May 31, 2017, the PPO issued official notice of its decision not to pursue criminal proceedings against Bruker Korea. Additionally, since December 2016, various Korean governmental entities imposed suspensions on Bruker Korea, with overlapping

111

Table of Contents

suspension periods ranging from three to six months. During the periods of these suspensions, Bruker Korea was prohibited from bidding for or conducting sales to Korean governmental agencies. Sales to these customers were less than 1% of the Company's revenue for the year ended December 31, 2016. At December 31, 2017, all such suspension periods have lapsed. The Company considers these matters resolved and no additional payments are owed or accrued as of December 31, 2017 in connection with such resolutions.

Operating Leases

        Certain buildings, office equipment and vehicles are leased under agreements that are accounted for as operating leases. Total rental expense under operating leases was $23.7 million, $22.0 million and $23.0 million during the years ended December 31, 2017, 2016 and 2015, respectively. Future minimum lease payments under non-cancelable operating leases at December 31, 2017, for each of the next five years and thereafter are as follows (in millions):

Capital Leases

        The Company leases certain assets under agreements that are classified as capital leases. The cost of these assets under the capital leases is included in the consolidated balance sheets as property, plant and equipment and was $0.9 million at December 31, 2017. Accumulated amortization of the leased buildings at December 31, 2017 was $0.5 million. There were no assets under capital lease agreements as of December 31, 2016. Amortization expense related to assets under capital leases was included in depreciation expense. The obligations related to capital leases was recorded as a component of long-term debt or the current portion of long-term debt in the consolidated balance sheets, depending on when the lease payments are due.

Unconditional Purchase Commitments

        The Company has entered into unconditional purchase commitments, in the ordinary course of business, that include agreements to purchase goods, services or fixed assets and to pay royalties that are enforceable and legally binding and that specify all significant terms including: fixed or minimum quantities to be purchased; fixed, minimum or variable price provisions; and the approximate timing of the transaction. Purchase commitments exclude agreements that are cancelable at any time without penalty. The aggregate amount of the Company's unconditional purchase commitments totaled $164.0 million at December 31, 2017 and the majority of these commitments are expected to be settled during 2018.

License Agreements

        The Company has entered into cross-licensing agreements for various technologies that allow other companies to utilize certain of its patents and related technologies over various periods or into perpetuity. Income from these agreements for the years ended December 31, 2017, 2016 and 2015 was $2.1 million, $1.9 million and $2.5 million, respectively, and is classified in other revenue in the consolidated statements of income and comprehensive income. The unearned portions of proceeds from the cross-licensing agreements are classified as short-term or long-term deferred revenue depending on when the revenue will be earned.

112

Table of Contents

        The Company has also entered into license agreements allowing it to utilize certain patents. If these patents are used in connection with a commercial product sale, the Company pays royalties on the related product revenues. Licensing fees for the years ended December 31, 2017, 2016 and 2015, were $3.5 million, $3.0 million and $3.2 million, respectively, and are recorded in cost of product revenue in the consolidated statements of income and comprehensive income.

Letters of Credit and Guarantees

        At December 31, 2017 and 2016, the Company had bank guarantees of $138.8 million and $131.5 million, respectively, related primarily to customer advances. These arrangements guarantee the refund of advance payments received from customers in the event that the merchandise is not delivered or warranty obligations are not fulfilled in compliance with the terms of the contract. These guarantees affect the availability of the Company's lines of credit.

Indemnifications

        The Company enters into standard indemnification arrangements in the Company's ordinary course of business. Pursuant to these arrangements, the Company indemnifies, holds harmless, and agrees to reimburse the indemnified parties for losses suffered or incurred by the indemnified party. These parties are generally the Company's business partners or customers, in connection with any patent, or any copyright or other intellectual property infringement claim by any third party with respect to its products. The term of these indemnification agreements is generally perpetual any time after the execution of the agreement. The maximum potential amount of future payments the Company could be required to make under these agreements is unlimited. The Company believes the estimated fair value of these agreements is minimal based on historical experiences.

Note 15—Shareholders' Equity

Share Repurchase Program

        In May 2015, the Company's Board of Directors approved a share repurchase program (the "Anti-Dilutive Repurchase Program") under which the Company was authorized to repurchase the Company's common stock in amounts intended to approximately offset, on an annual basis, the dilutive effect of shares that have been, or may be, issued pursuant to option or restricted stock awards under the Company's incentive compensation plans. In 2015, a total of 1,245,000 shares were repurchased at an aggregate cost of $24.9 million under the Anti-Dilutive Repurchase Program.

        In November 2015, the Company's Board of Directors suspended the Anti-Dilutive Repurchase Program until January 1, 2017 and approved an additional share repurchase program. This program authorized repurchases of common stock up to $225 million from time to time, in amounts, at prices, and at such times as the Company deemed appropriate, subject to market conditions, legal requirements and other considerations. A total of 9,312,522 shares were repurchased at an aggregate cost of $225.0 million as of December 31, 2016 under that completed repurchase program.

        In May 2017, the Company's Board of Directors approved an additional share repurchase program (the "Repurchase Program") under which repurchases of common stock up to $225.0 million were authorized to occur from time to time, in amounts, at prices, and at such times as the Company deems appropriate, subject to market conditions, legal requirements and other considerations. A total of 5,318,063 shares were repurchased at an aggregate cost of $152.2 million in the year ended December 31, 2017 under the Repurchase Program. Any future repurchases will be funded from cash on hand, future cash flows from operations and available borrowings under the revolving credit facility.

        The repurchased shares are reflected within Treasury stock in the accompanying consolidated balance sheet at December 31, 2017 and 2016.

Under the dividend policy, the Company will target a cash dividend to the Company's shareholders in the amount of $0.16 per share per annum, payable in equal quarterly installments. The following is a summary of the dividends paid in the years ended December 31, 2017 and 2016 (in millions):

 

        Subsequent dividend declarations and the establishment of record and payment dates for such future dividend payments, if any, are subject to the Board of Directors' continuing determination that the dividend policy is in the best interests of the Company's shareholders. The dividend policy may be suspended or cancelled at the discretion of the Board of Directors at any time.

Accumulated Other Comprehensive Income (Loss)

        The following is a summary of the components of accumulated other comprehensive income (loss), net of tax, at December 31, (in millions):

Note 16—Stock-Based Compensation

        In February 2010, the Bruker BioSciences Corporation Amended and Restated 2000 Stock Option Plan (the "2000 Plan"), expired at the end of its scheduled ten-year term. On March 9, 2010, the Company's Board of Directors unanimously approved and adopted the Bruker Corporation 2010 Incentive Compensation Plan (the "2010 Plan"), and on May 14, 2010, the 2010 Plan was approved by the Company's stockholders. The 2010 Plan provided for the issuance of up to 8,000,000 shares of the Company's common stock. The 2010 Plan allowed a committee of the Board of Directors (the

114

Table of Contents

"Compensation Committee") to grant incentive stock options, non-qualified stock options and restricted stock awards. The Compensation Committee had the authority to determine which employees would receive the awards, the amount of the awards and other terms and conditions of any awards. Awards granted under the 2010 Plan typically were made subject to a vesting period of three to five years.

        In May 2016, the Bruker Corporation 2016 Incentive Compensation Plan (the "2016 Plan") was approved by the Company's stockholders. With the approval of the 2016 Plan, no further grants will be made under the 2010 Plan. The 2016 Plan provides for the issuance of up to 9,500,000 shares of the Company's common stock and permits the grant of awards of non-qualified stock options, incentive stock options, stock appreciation rights, restricted stock, unrestricted stock, restricted stock units, performance shares and performance units, as well as cash-based awards. The 2016 Plan is administered by the Compensation Committee. The Compensation Committee has the authority to determine which employees will receive awards, the amount of any awards, and other terms and conditions of such awards. Stock option awards granted under the 2016 Plan typically vest over a period of three to four years.

        Stock option activity for the year ended December 31, 2017 was as follows:

        The weighted average fair value of options granted was $7.61, $7.72 and $7.82 per share for the years ended December 31, 2017, 2016 and 2015, respectively.

        The total intrinsic value of options exercised was $16.2 million, $11.2 million and $8.2 million for the years ended December 31, 2017, 2016 and 2015, respectively.

        Unrecognized pre-tax stock-based compensation expense of $8.3 million related to stock options awarded under the 2010 and 2016 Plans is expected to be recognized over the weighted average remaining service period of 2.2 years for stock options outstanding at December 31, 2017.

        Restricted shares of the Company's common stock are periodically awarded to executive officers, directors and certain key employees of the Company, subject to service restrictions, which vest ratably over periods of one to four years. The restricted shares of common stock may not be sold or

transferred during the restriction period. Stock-based compensation for restricted stock is recorded based on the stock price on the grant date and charged to expense ratably throughout the restriction period.

        The following table summarizes information about restricted stock award activity during the year ended December 31, 2017:

        The total fair value of restricted stock vested was $2.3 million, $1.5 million and $1.0 million for the years ended December 31, 2017, 2016 and 2015, respectively.

        Unrecognized pre-tax stock-based compensation expense of $1.1 million related to restricted stock awarded under the 2010 Plan is expected to be recognized over the weighted average remaining service period of 1.44 years for awards outstanding at December 31, 2017.

        Restricted stock units of the Company's common stock are periodically awarded to executive officers, directors and certain employees of the Company which vest ratably over a service periods of one to four years. Stock-based compensation for restricted stock units is recorded based on the stock price on the grant date and charged to expense ratably throughout the vesting period.

        The following table summarizes information about restricted stock unit activity for year ended December 31, 2017:

        The total fair value of restricted stock vested was $2.0 million for the year ended December 31, 2017. No restricted stock units vested in the years ended December 31, 2016 and 2015.

        Unrecognized pre-tax stock-based compensation expense of $13.2 million related to restricted stock units awarded under the 2016 Plan is expected to be recognized over the weighted average remaining service period of 3.38 years for units outstanding at December 31, 2017.

        In March 2016, the FASB issued ASU No. 2016-09, Stock Compensation—Improvements to Employee Share-Based Payment Accounting. The new standard simplifies accounting for share-based payment transactions, including income tax consequences and the classification of the tax impact on the statement of cash flows. The Company adopted this standard effective January 1, 2017. The ASU requires that the difference between the actual tax benefit realized upon exercise or vesting, as applicable, and the tax benefit recorded based on the fair value of the stock award at the time of grant (the "excess tax benefits") be reflected as a reduction of the current period provision for income taxes

with any shortfall recorded as an increase in the tax provision rather than as a component of changes to additional paid-in capital. The ASU also required the excess tax benefit realized be reflected as an operating cash flow rather than a financing cash flow. This standard was adopted by the Company on a modified retrospective basis with respect to the previously unrecognized windfalls, which resulted in a cumulative adjustment to retained earnings of $3.6 million as of January 1, 2017 related to the timing of when excess tax benefits are recognized. The Company adopted this standard on a prospective basis with respect to the statements of income and cash flows and recognized an excess tax benefit related to stock compensation which decreased income tax expense in the amount of $1.9 million for the year ended December 31, 2017. The excess tax benefits were previously recorded in equity. The Company continues to utilize a historical forfeiture rate to estimate future forfeitures.

Restructuring Initiatives

2016

        The Company commenced a restructuring initiative in 2016 to address lower demand in the Bruker CALID and Bruker Nano Groups as a result of delays in European academic funding and ongoing weakness in several of the industrial end market segments that affect the Bruker Nano Group. This initiative was intended to improve the Bruker CALID and Bruker Nano Group operating results in response to these market conditions. Restructuring actions will result in a reduction of approximately 125 employees within the Bruker CALID and Bruker Nano Groups.

        The following is a summary of the restructuring expenses related to this initiative which are recorded in the accompanying consolidated statements of income and comprehensive income for the years ended December 31, 2017 and 2016:

2015

        The Company commenced a restructuring initiative in the second quarter of 2015 within the Bruker BioSpin Group, which was developed as a result of a revenue decline that occurred during the second half of 2014 and continued during the first half of 2015. This initiative was intended to improve Bruker BioSpin Group's operating results. Restructuring actions resulted in a reduction of employee headcount within the Bruker BioSpin Group of approximately 9% and the closure and consolidation of a Bruker BioSpin Group manufacturing facility.

        The following is a summary of the restructuring expenses related to this initiative which are recorded in the accompanying consolidated statements of income and comprehensive income for years ended December 31, 2017, 2016 and 2015:

        As of December 31, 2017, expenses incurred under this restructuring initiative were substantially complete.

        Restructuring charges for the years ended December 31, 2017, 2016 and 2015 included charges for various other programs which were recorded in the accompanying consolidated statements of income and comprehensive income as follows:

Note 21—Recent Accounting Pronouncements

        In January 2017, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") 2017-04, Intangibles-Goodwill and Other (Topic 350): Simplifying the Test for Goodwill Impairment. The new standard simplifies the subsequent measurement of goodwill by eliminating the second step of the goodwill impairment test. This ASU will be applied prospectively and is effective for annual or interim goodwill impairment tests in fiscal years beginning after December 15, 2019. The adoption of this standard is not expected to have a material impact on the Company's consolidated financial statements upon adoption.

        In January 2017, the FASB issued ASU No. 2017-01, Business Combinations (Topic 805): Clarifying the Definition of a Business. This new standard clarifies the definition of a business and provides a screen to determine when an integrated set of assets and activities is not a business. The screen requires that when substantially all of the fair value of the gross assets acquired (or disposed of) is concentrated in a single identifiable asset or a group of similar identifiable assets, the set is not a business. This new standard was adopted as of the effective date of January 1, 2018. The Company has evaluated the provisions of this standard and has determined that the impact of adoption of ASU No. 2017-01 was not material to the consolidated financial statements.

        In October 2016, the FASB issued ASU No. 2016-16, Income Taxes (Topic 740)—Intra-Entity Transfer of Assets Other than Inventory. The new standard requires recognition of current and deferred income taxes resulting from an intra-entity transfer of any asset (excluding inventory) when the transfer occurs. This is a change from existing U.S. GAAP which prohibits recognition of current and deferred income taxes until the asset is sold to a third party. This new standard was adopted as of the effective date of January 1, 2018. The Company has evaluated the provisions of this standard and has determined that the impact of adoption of ASU No. 2016-16 was not material to the consolidated financial statements.

        In February 2016, the FASB issued ASU No. 2016-02, Leases. The new standard provides guidance on the recognition, measurement, presentation, and disclosure of leases. The new standard supersedes present U.S. GAAP guidance on leases and requires substantially all leases to be reported on the balance sheet as right-of-use assets and lease liabilities, as well as additional disclosures. The new standard is effective as of January 1, 2019, and early adoption is permitted. The Company is evaluating the provisions of this standard and has not determined what impact the adoption of ASU No. 2016-02 will have on the Company's consolidated financial statements.

        In May 2014, the FASB issued ASU No. 2014-09, Revenue from Contracts with Customers, which supersedes the revenue recognition requirements under Accounting Standards Codification (ASC) Topic 605. The new guidance was the result of a joint project between the FASB and the International Accounting Standards Board to clarify the principles for recognizing revenue and to develop common revenue standards for U.S. GAAP and International Financial Reporting Standards. The core principle of the new guidance is that revenue should be recognized to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. In August 2015, the FASB elected to defer the effective date of ASU No. 2014-09 by one year to annual periods beginning after December 15, 2017, with early application permitted as of the original effective date. The new guidance may be applied on a retrospective basis for all prior periods presented, or on a modified retrospective basis with the cumulative effect of the new guidance as of the date of initial application. The new guidance will be

122

effective for the Company as of January 1, 2018 and the Company currently intends to use the modified retrospective transition method.

        Under the new guidance, there are specific criteria to determine if a performance obligation should be recognized over time or at a point in time. Accordingly, the Company has identified certain project-based orders in the BEST Segment and CBRNE detection orders in the Bruker CALID Group for which the timing of when the Company recognizes revenue may be impacted. Due to the complexity of these project-based orders, revenue recognition under the new standard is highly dependent on specific contract terms.

        During the fourth quarter of 2017, the Company substantially completed the assessment over the impact that this new standard will have on its consolidated balance sheets. The Company preliminarily expects to recognize an adjustment of approximately $6.0 million to retained earnings on January 1, 2018 to reflect the cumulative effect of the accounting changes made upon the adoption of the standard. The finalization of the assessment may result in significant changes to the estimates that may materially impact the preliminary estimate of the cumulative effect.

ITEM 9    CHANGES IN AND DISAGREEMENTS WITH ACCOUNTANTS ON AUDITING AND FINANCIAL DISCLOSURE

        At a meeting held on June 1, 2016, the audit committee of the Company's Board of Directors approved the dismissal of Ernst & Young LLP ("Ernst & Young") as the Company's independent registered public accounting firm, effective June 1, 2016, and the appointment of PricewaterhouseCoopers LLP as the Company's independent registered public accounting firm, effective June 1, 2016, to perform independent audit services for the fiscal year ending December 31, 2016.

        The report of Ernst & Young on the consolidated financial statements of the Company for the fiscal year ended December 31, 2015 did not contain an adverse opinion or disclaimer of opinion and were not qualified or modified as to uncertainty, audit scope, or accounting principles.

        In connection with the audit of our financial statements for the fiscal year ended December 31, 2015, and in the subsequent interim period through June 1, 2016, there were no "disagreements" (as that term is defined in Item 304(a)(1)(iv) of Regulation S-K and the related instructions) with Ernst & Young on any matter of accounting principles or practices, financial statement disclosure, or auditing scope and procedures, which, if not resolved to the satisfaction of Ernst & Young, would have caused Ernst & Young to make reference to the matter in their reports for such years. There were no "reportable events" as that term is described in Item 304(a)(1)(v) of Regulation S-K, except for a material weakness in the Company's internal control over financial reporting as of December 31, 2015 concerning the accounting for income taxes, which material weakness was identified subsequent to the filing of our Annual Report on Form 10-K for the year ended December 31, 2015.

        As a result of such material weakness, our management concluded in November 2016 that the Company's internal control over financial reporting was not effective at December 31, 2015. On November 15, 2016, the Company filed Amendment No. 1 to its Annual Report on Form 10-K for the fiscal year ended December 31, 2015, as well as amendments to each of its Quarterly Reports on Form 10-Q for the periods ended March 31, 2016, and June 30, 2016, to reflect the conclusion by management that there was a material weakness in internal control over financial reporting as of the end of the periods covered by those reports. The Company's Amendment No. 1 to its Annual Report on Form 10-K for the fiscal year ended December 31, 2015 also included revised auditor's reports from Ernst & Young stating that the Company's internal control over financial reporting at December 31, 2015 was not effective.

ITEM 9A    CONTROLS AND PROCEDURES

Disclosure Controls and Procedures

        We have established disclosure controls and procedures (as such term is defined in Rules 13a-15(e) and 15d-15(e) under the Securities Exchange Act of 1934, as amended (the "Exchange Act")) that are designed to ensure that information required to be disclosed in the reports that we file or submit under the Exchange Act is recorded, processed, summarized and reported within the time periods specified in the rules and forms of the SEC and to ensure that information required to be disclosed is accumulated and communicated to management, including our Chief Executive Officer (principal executive officer) and Chief Financial Officer (principal financial officer), to allow timely decisions regarding required disclosures. Under the supervision and with the participation of our management, including our Chief Executive Officer and Chief Financial Officer, we conducted an evaluation of the effectiveness of our disclosure controls and procedures as of December 31, 2017. Based on this evaluation, our Chief Executive Officer and Chief Financial Officer concluded that our disclosure controls and procedures were effective at a reasonable assurance level as of December 31, 2017.

Management's Report on Internal Control over Financial Reporting

        Our management is responsible for establishing and maintaining adequate internal control over financial reporting. Under the supervision and with the participation of our management, including our Chief Executive Officer and Chief Financial Officer, we conducted an evaluation of the effectiveness of our internal control over financial reporting as of December 31, 2017, based on the criteria set forth by the Committee of Sponsoring Organizations of the Treadway Commission (COSO) in Internal Control—Integrated Framework (2013). Based on this evaluation, management concluded that our internal control over financial reporting was effective as of December 31, 2017.

        We excluded Hysitron, Incorporated ("Hysitron") from our assessment of internal control over financial reporting as of December 31, 2017 because it was acquired by the Company in a purchase business combination during 2017. The total assets and total revenues of Hysitron, represent 0.7% and 0.9%, respectively, of the related consolidated financial statement amounts as of and for the year ended December 31, 2017.

        The effectiveness of our internal control over financial reporting as of December 31, 2017 has been audited by PricewaterhouseCoopers LLP, an independent registered public accounting firm, as stated in their report which appears herein.

Changes in Internal Control over Financial Reporting

        There were no changes in our internal control over financial reporting that occurred during the quarter ended December 31, 2017 that materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.
