On June 8, 2004, the Company completed the sale of PTI S.p.A. to a group of investors comprised of that subsidiary’s senior management for $5.3 million. The MicroSep Business is accounted for as a discontinued operation in the Consolidated Financial Statements in the 2004 period in accordance with SFAS No. 144, “Accounting for the Impairment or Disposal of Long-Lived Assets”.

     The following sections of this Item 1 refer to the Company’s continuing operations, except where noted. Accordingly, dollar amounts and percentages presented below in this Item 1 for all periods reflect continuing operations by excluding the MicroSep Business. See Note 3 of the Notes to Consolidated Financial Statements in the 2006 Annual Report, which Note is herein incorporated by reference.

PRODUCTS

     The Company’s products are described below. See Note 15 of the Notes to Consolidated Financial Statements in the 2006 Annual Report for financial information regarding segments, which Note is herein incorporated by reference.

FILTRATION/FLUID FLOW

     The Filtration/Fluid Flow segment accounted for approximately 38%, 40% and 41% of the Company’s total revenue in fiscal years 2006, 2005 and 2004, respectively.

     Filtertek develops and manufactures a broad range of specialized filtration and fluid/flow products at its facilities in North America, South America and Europe. Filtertek’s products, which are centered around its insert injection-molding technology wherein a filter medium is inserted into the tooling prior to injection-molding of the filter housing, have widespread applications in the medical and healthcare, automotive fluid system, consumer appliance and other commercial and industrial markets. Typical Filtertek customers may require daily production of thousands of units, at very high levels of quality, that are generally produced in highly-automated manufacturing cells. Many of Filtertek’s products are produced utilizing patented designs or proprietary product or process design, or both. Filtertek’s products are typically supplied to original equipment manufacturers under long-term contracts. The Tek Packaging Division of Filtertek Inc. produces highly engineered thermal-formed and security packaging products for medical, food and electronics products.

     PTI is a leading supplier of filtration products serving the commercial aerospace, military aerospace and various industrial markets. The industrial markets include chemical processing, automotive and mobile equipment. Products include filter elements, assemblies, modules, indicators and other related components. All products must meet stringent quality requirements and withstand severe operating conditions. Product applications include aircraft and mobile equipment hydraulic systems, aircraft engines, plant equipment and automotive transmissions. PTI supplies product worldwide to original equipment manufacturers and the U.S. government under long term contracts, and to the commercial aftermarkets through distribution channels.

     VACCO supplies flow control products to the aerospace industry for use in aircraft, satellite propulsion systems, satellite launch vehicles and the space shuttle. VACCO also uses its etched disc technology to produce quiet valves and manifolds for U.S. Navy applications.

COMMUNICATIONS

     The Communications segment accounted for approximately 34%, 32% and 33% of the Company’s total revenue in fiscal years 2006, 2005 and 2004, respectively.

     DCSI is a leading manufacturer of two-way power line communication systems for the electric utility industry (the “TWACS^® systems”), which are composed of equipment (primarily meter modules and equipment for central stations and substations), software and support services. The TWACS Next Generation (“TNG”) software is being developed jointly with a third-party contractor. This development continued in fiscal 2006, leading to the commercial release of its second version, which was delivered to a second customer location and underwent operational testing. Currently, additional versions of the TNG software are under development and are scheduled for commercial release in fiscal 2007. The TWACS systems provide electric utilities with a patented communication technology for automatic meter reading, load control, interval data, outage assessment/restoration monitoring, remote service disconnect/connect, time-of-use data for critical peak pricing, tamper/theft detection and pre-paid metering. Revenue from the TWACS systems, which may be considered a class of similar products, accounted for approximately 26%, 28% and 31% of the Company’s total revenue in fiscal years 2006, 2005 and 2004, respectively. In November 2005, DCSI received a contract from Pacific Gas and Electric Company (“PG&E”) in support of the electric portion of PG&E’s Advanced Metering Infrastructure (“AMI”) Project. The current AMI program plan provides for the coverage of up to approximately five million electric endpoints over the five-year full deployment period. System testing of a small test system was successfully completed in fiscal year 2006, and PG&E received approval from the California Public Utility Commission for the entire AMI project. DCSI has agreed to deliver to PG&E versions of its newly developed TNG software as they become available and are tested. Delivery of the final version, for which DCSI has committed, is currently anticipated in the fourth quarter of fiscal 2007. The contract provides for remedies including, but not limited to, liquidated damages in the event of DCSI’s delayed development or delivery of hardware and software. The total anticipated contract value from commencement through the five-year full deployment period is approximately $310 million. Equipment will be purchased by PG&E only upon issuance of purchase orders. See Item 1.A Risk Factors.

     Hexagram provides, through its STAR^® network, wireless RF data communications systems primarily to gas and water utilities for automatic meter reading applications. In November 2005, Hexagram received a contract from PG&E to provide its communications system for the gas meter portion of PG&E’s AMI Project. The total anticipated contract revenue through the full five-year deployment is approximately $225 million. This contract is subject to contingencies and uncertainties similar to those associated with the DCSI — PG&E contract described above except that the TNG software is not applicable to this contract.

     Nexus provides energy companies with software solutions that add value to their existing billing and metering infrastructure to allow both the energy company and its customers to better manage energy-driven transactions and decision-making. Nexus’ analytics-based software applications are used by over 85 major energy organizations worldwide. In fiscal 2006, Nexus implemented a Meter Data Management System for PPL Electric Utilities that integrates with the TWACS^® system, and processes and manages hourly data collected from 1.375 million meters.

     Comtrak manufactures advanced video security monitoring systems for commercial and industrial applications. Comtrak is continuing to work jointly with ADT Security Services, Inc., who is selling this system under its SecurVision^® trademark to a variety of markets.

TEST

     The Test segment accounted for approximately 28%, 28% and 26% of the Company’s total revenue in fiscal years 2006, 2005 and 2004, respectively.

     ETS-Lindgren designs and manufactures products to measure and contain magnetic, electromagnetic and acoustic energy. It supplies customers with a broad range of isolated environments including RF test enclosures, acoustic test enclosures, RF and magnetically shielded rooms, secure communication facilities and broadcast and recording studios. Many of these facilities include proprietary features such as shielded doors and windows. ETS-Lindgren also provides the design, program management, installation and

integration services required to successfully complete these types of facilities.

     ETS-Lindgren also supplies customers with a broad range of components including RF absorptive materials, RF filters, active compensation systems, antennas, antenna masts, turntables and electric and magnetic probes, RF test cells, proprietary measurement software and other test accessories required to perform a variety of tests. ETS-Lindgren also offers a variety of services including calibration for antennas and field probes, chamber certification, field surveys, customer training and a variety of product tests. ETS-Lindgren operates the following accredited test labs: American Association for Laboratory Accreditation (“A2LA”), National Voluntary Laboratory Accreditation Program (“NAVLAP”) and CTIA-The Wireless Association (“CTIA”). In addition, ETS-Lindgren serves the acoustics, medical, health and safety, electronics, wireless communications, automotive and defense markets.

MARKETING AND SALES

     The Filtration/Fluid Flow and Test segments’ products generally are distributed to customers through a domestic and foreign network of distributors, sales representatives and in-house salespersons. DCSI’s sales to investor-owned utilities are primarily made directly to the utilities. DCSI primarily utilizes distributors and sales representatives to sell its systems to the electric utility cooperative and municipal markets. Hexagram has an exclusive agreement with Neptune Technology Group, Inc. for the distribution of its products to its water utility customers, and utilizes in-house salespersons to cover electric, gas and combination utilities. Nexus markets its products utilizing its in-house sales force.

     The Company’s international sales accounted for approximately 22%, 24% and 22% of the Company’s total sales in the fiscal years ended September 30, 2006, 2005 and 2004, respectively. See Note 15 of the Notes to Consolidated Financial Statements in the 2006 Annual Report for financial information regarding geographic areas, which Note is herein incorporated by reference.

     Some of the Company’s products are sold directly or indirectly to the U.S. Government under contracts with the Army, Navy and Air Force and subcontracts with prime contractors of such entities. Direct and indirect sales to the U.S. Government accounted for approximately 6%, 8% and 8% of the Company’s total sales in the fiscal years ended September 30, 2006, 2005 and 2004, respectively.

INTELLECTUAL PROPERTY

     The Company owns or has other rights in various forms of intellectual property (i.e., patents, trademarks, service marks, copyrights, mask works, trade secrets and other items). As a major supplier of engineered products to growing industrial and commercial markets, the Company emphasizes developing intellectual property and protecting its rights therein. However, the scope of protection afforded by intellectual property rights, including those of the Company, is often uncertain and involves complex legal and factual issues. Some intellectual property rights, such as patents, have only a limited term. Also, there can be no assurance that third parties will not infringe or design around the Company’s intellectual property. Policing unauthorized use of intellectual property is difficult, and copyright infringement is a persistent problem for many companies, particularly in some international markets. In addition, the Company may not elect to pursue an unauthorized user due to the high costs and uncertainties associated with litigation. Further, there can be no assurance that courts will ultimately hold issued patents valid and enforceable. See Item 1.A Risk Factors.

     With respect to the Filtration/Fluid Flow segment, an increasing number of products are based on patented or otherwise proprietary technology that sets them apart from the competition. Of particular importance to Filtertek is a U.S. patent covering certain transmission sump filters, which will expire in 2009. Also, Filtertek receives significant income from licensing and cost recovery efforts concerning its U.S. patent on certain needle-free medical connection devices, having claims which will expire on various dates between 2011 and 2013. VACCO’s proprietary quieting technology, which it protects as trade secrets, is a significant differentiator for products supplied to the U.S. Navy submarine fleet. In June 2005, the Company abandoned its plans to commercialize certain PTI sensor products, resulting in the abandonment of certain related patents and a related license agreement. See “Management’s Discussion and Analysis”—“Asset Impairment-2005” appearing in the 2006 Annual Report.

     In the Communications segment, many of the products are based on patented or otherwise proprietary technology, including the Company’s TWACS technology. The TWACS systems are protected primarily by a number of patents expiring on various dates ending in 2017. Patents covering significant aspects of the TWACS technology will expire in 2007 and 2010 for outbound signal reception, 2007 for inbound signal detection, and 2017 for inbound signal generation. The Communications segment policy is to seek patent and/or other forms of intellectual property protection on new and improved products, components of products and methods of operation for its businesses, as such developments are made. The Company plans to protect the TNG software as trade secrets. Hexagram holds two significant patents which cover the operation of its STAR^® network communications systems. These will expire in 2015 and 2016.

     In the Test segment, patent protection has been sought for significant inventions. Examples of such inventions include novel designs for window and door assemblies used in shielded enclosures and anechoic chambers as well as improved acoustic techniques for sound isolation.

     The Company considers its patent and other intellectual property to be of significant value in each of its segments. The Communications segment owns intellectual property, including its TWACS technology, which it deems necessary or desirable for the manufacture, use or sale of its products. See the references to the TNG software above in this section and in “Communications” on page 3 of this report. No other segment is materially dependent on any single patent, group of patents or other intellectual property.

BACKLOG

     Total Company backlog at September 30, 2006 was $253.4 million, representing an increase of $20.3 million (8.7%) from the beginning of the fiscal year backlog of $233.1 million. The backlog of firm orders at September 30, 2006 and September 30, 2005, respectively, was: $78.6 million and $80.5 million for Filtration/Fluid Flow; $119.0 million and $87.8 million for Communications; and $55.8 million and $64.8 million for Test. As of September 30, 2006, it is estimated that domestic customers accounted for approximately 81% of the Company’s total firm orders, and international customers accounted for approximately 19%. Of the Company’s total backlog of orders at September 30, 2006, approximately 77% is expected to be completed in the fiscal year ending September 30, 2007.

PURCHASED COMPONENTS AND RAW MATERIALS

     The Company’s products require a wide variety of components and materials. Although the Company has multiple sources of supply for most of its materials requirements, certain components and raw materials are supplied by sole-source vendors, and the Company’s ability to perform certain contracts depends on their performance. In the past, these required raw materials and various purchased components generally have been available in sufficient quantities. However, in each of the Company’s segments, there are instances of some risk of shortages of materials or components due to reliance on sole or limited source of supply. See Item 1.A Risk Factors.

     The Filtration/Fluid Flow segment purchases supplies from a wide array of vendors. In most instances, multiple vendors of raw materials are screened during a qualification process to ensure that there will not be an interruption of supply should one of them discontinue operations. Nonetheless, in some situations, there is a risk of shortages due to reliance on a limited number of suppliers or because of price fluctuations due to the nature of the raw materials, as in the case of petroleum-based resins utilized by Filtertek.

     In the Communications segment, DCSI has arrangements with three independent manufacturers which produce and supply substantially all of DCSI’s end-products. Two of these manufacturers are industry leaders with world-wide operations. Each of these manufacturers is directed by DCSI to purchase certain unique raw material components from suppliers designated by DCSI. DCSI also has contracts with certain of the raw material suppliers, directing them to supply such raw materials to DCSI’s manufacturers. Hexagram has a contract with an independent manufacturer which produces and supplies substantially all of Hexagram’s

end-products, as well as contracts with several of the suppliers of the raw materials that are incorporated into such end-products. Hexagram is in the process of finalizing a new contract with one of the primary suppliers used by DCSI, which will be a second source for the production of Hexagram’s end-products. The Company believes that the above-described manufacturers and suppliers will be reliable sources for DCSI’s and Hexagram’s end-products for the foreseeable future.

     The Test segment is a vertically integrated supplier of EM shielding products, producing most of its critical RF components. However, this segment purchases significant quantities of raw materials such as steel, copper, nickel and wood. Accordingly, the segment is subject to price fluctuations in the worldwide raw materials markets. In fiscal 2006, this segment experienced significant price increases in the metal markets as compared to the prior year.

COMPETITION

     Competition in the Company’s major markets is broadly based and global in scope. The Company faces intense competition from a large number of companies for nearly all of its products. Competition can be particularly intense during periods of economic slowdown, and this has been experienced in the past in some of the Filtration/Fluid Flow markets. Although the Company is a leading supplier in several of the markets it serves, it maintains a relatively small share of the business in many of the other markets it serves. Individual competitors range in size from annual revenues of less than $1 million to billion dollar enterprises. Because of the specialized nature of the Company’s products, its competitive position with respect to its products cannot be precisely stated. However, DCSI is believed to be a leading supplier in the fixed network segment of the automatic meter reading (“AMR”) market. This fixed network segment comprises a substantial part of the electric portion of the total AMR market for electric utilities. Substantial efforts are required in order to maintain existing business levels. In the Company’s major served markets, competition is driven primarily by quality, technology, price and delivery performance. See Item 1.A Risk Factors.

     Pall Corporation, SPX Filtran and SoFrance are the primary competitors in the Filtration/Fluid Flow markets. Other significant competitors in these markets include Clarcor Inc., Cummins Filtration and Moog Inc.

     Primary competitors of the Communications segment in the utility communications market include Itron, Inc., Hunt Technologies Inc., Cellnet Technology Inc., Cannon Technologies Inc., Sensus Metering Systems Inc., Elster Electricity, L.L.C, Comverge, Inc. and Lodestar Corporation.

     The Test segment is the global leader in the EM shielding market. Significant competitors in this served market include TDK RF Solutions Inc., Albatross GmbH, IMEDCO AG and Cuming Corporation.

RESEARCH AND DEVELOPMENT

     Research and development and the Company’s technological expertise are important factors in the Company’s business. Research and development programs are designed to develop technology for new products or to extend or upgrade the capability of existing products, and to enhance their commercial potential.

     The Company performs research and development at its own expense, and also engages in research and development funded by customers. For the fiscal years ended September 30, 2006, 2005 and 2004, total Company-sponsored research and development expenses were approximately $20.0 million, $16.8 million and $12.2 million, respectively. Total customer-sponsored research and development expenses were approximately $6.3 million, $5.7 million and $6.1 million for the fiscal years ended September 30, 2006, 2005 and 2004, respectively. All of the foregoing expense amounts exclude certain engineering costs primarily associated with product line extensions, modifications and maintenance, which amounted to approximately $9.1 million, $7.8 million and $9.6 million for the fiscal years ended September 30, 2006, 2005 and 2004, respectively.

ENVIRONMENTAL MATTERS

     The Company is involved in various stages of investigation and cleanup relating to environmental matters. It is very difficult to estimate the potential costs of such matters and the possible impact of these costs on the Company at this time due in part to: the uncertainty regarding the extent of pollution; the complexity of Government laws and regulations and their interpretations; the varying costs and effectiveness of alternative cleanup technologies and methods; the uncertain level of insurance or other types of cost recovery; and in the case of off-site waste disposal facilities, the uncertain level of the Company’s relative involvement and the possibility of joint and several liability with other contributors under applicable law. Based on information currently available, the Company does not believe that the aggregate costs involved in the resolution of any of its environmental matters will have a material adverse effect on the Company’s financial statements.

GOVERNMENT CONTRACTS

     The Company’s contracts with the U.S. Government and subcontracts with prime contractors of the U.S. Government are primarily firm fixed-price contracts under which work is performed and paid for at a fixed amount without adjustment for the actual costs experienced in connection with the contracts. Therefore, unless the customer actually or constructively alters or impedes the work performed, all risk of loss due to cost overruns is borne by the Company. All Government prime contracts and virtually all of the Company’s subcontracts provide that they may be terminated at the convenience of the Government. Upon such termination, the Company is normally entitled to receive equitable compensation. See “Marketing And Sales” in this Item 1 and Item 1.A Risk Factors for additional information regarding Government contracts.

EMPLOYEES

     As of November 30, 2006, the Company employed approximately 2,685 persons.

FINANCING

     On October 6, 2004, the Company entered into a $100 million five-year revolving credit facility with a $50 million increase option. This facility is available for direct borrowings and/or the issuance of letters of credit, and is provided by a group of six banks, led by Wells Fargo Bank as agent, with a maturity of October 6, 2009. The facility is secured by the unlimited guaranty of the Company’s material domestic subsidiaries and a 65% pledge of the material foreign subsidiaries’ share equity. See “Management’s Discussion and Analysis — Capital Resources and Liquidity” in the 2006 Annual Report, and Note 10 of the Notes to Consolidated Financial Statements in the 2006 Annual Report, which information is herein incorporated by reference.

HISTORY OF THE BUSINESS

     ESCO was incorporated in Missouri in August 1990 as a wholly-owned subsidiary of Emerson Electric Co. (“Emerson”) to be the indirect holding company for several Emerson subsidiaries, which were primarily in the defense business. Ownership of ESCO and its subsidiaries was distributed on October 19, 1990 by Emerson to its shareholders through a special distribution. Since that time, through a series of acquisitions and divestitures, the Company has shifted its primary focus from defense contracting to the supply of engineered products marketed to industrial and commercial users. Effective July 10, 2000, ESCO changed its name from ESCO Electronics Corporation to ESCO Technologies Inc.

     The MicroSep Business, which was divested in fiscal 2004, is discussed under “Discontinued Operations” in this Item 1.

AVAILABLE INFORMATION

     The Company makes available free of charge through its Internet website, www.escotechnologies.com, its annual report on Form 10-K, quarterly reports on Form 10-Q, current reports on Form 8-K and amendments to those reports filed or furnished pursuant to Section 13(a) or 15(d) of the Securities Exchange Act of 1934, as amended, as soon as reasonably practicable after such material is electronically filed with or furnished to the Securities and Exchange Commission.

Item 1A. Risk Factors

This Form 10-K, including Item 1 “Business,” Item 2 “Properties”, Item 3 “Legal Proceedings” and Item 7 “Management’s Discussion and Analysis of Financial Condition and Results of Operations” (incorporated by reference to “Management’s Discussion and Analysis” appearing in the 2006 Annual Report), contains “forward-looking statements” within the meaning of the safe harbor provisions of the federal securities laws. In addition to the risks and uncertainties discussed elsewhere in this Form 10-K, the following are important risk factors which could cause actual results and events to differ materially from those contained in any forward-looking statements.

A SIGNIFICANT PORTION OF COMMUNICATIONS SEGMENT REVENUES IS GENERATED BY A LIMITED NUMBER OF LARGE CONTRACTS.

     A significant portion of the Communications segment’s business is dependent on several large contracts with customers. The largest of these are two contracts to sell electric and gas automatic meter reading systems to PG&E over a period of approximately five years. These projects, which represent a potential high source of revenue, are subject to cancellation or reduction in volume by PG&E, delays, regulatory actions and the Company’s ability to develop advanced products and successfully perform the contracts. The loss of revenue which would result from cancellations, delays, reductions, regulatory actions or the Company’s failure to perform in connection with these projects could have a material adverse effect on the Company’s business, results of operations and financial condition as a whole.

FAILURE OR DELAY IN NEW PRODUCT DEVELOPMENT COULD REDUCE THE COMPANY’S FUTURE SALES.

     Much of the Company’s business is dependent on the continuous development of new products and technologies to meet the changing needs of the Company’s markets on a cost-effective basis. Many of these markets are highly technical from an engineering standpoint, and the relevant technologies are subject to rapid change. For example, the continued development of the TWACS Next Generation (“TNG”) software is critical to the continued sales growth of DCSI. Failure to deliver the final version of TNG, to which DCSI has committed under the PG&E contract, could constitute an event of default and adversely impact expected revenues.

     If the Company fails to timely enhance existing products or develop new products, sales opportunities could be lost, which would adversely affect business. In addition, in some existing contracts with customers, the Company has made commitments to develop and deliver new products. If the Company fails to meet these commitments, the default could result in the imposition of contractual penalties including termination. The inability to enhance existing products in a timely manner could make the products less competitive, while the inability to successfully develop new products may limit growth opportunities. Delays in product development may also require greater investment in research and development. Increased costs associated with new product development and product enhancements could adversely affect operating results. The costs of new product development may not be recoverable if demand for the products is not as anticipated.

CERTAIN MANUFACTURING OPERATIONS ARE DEPENDENT ON A SMALL NUMBER OF THIRD-PARTY SUPPLIERS

     A significant part of the Communications segment’s manufacturing operations relies on a small number of third-party manufacturers to supply the segment’s products. For example, DCSI has arrangements with three manufacturers which produce and supply substantially all of DCSI’s end-products. Two of these suppliers are located in Mexico. A significant disruption (for example, a strike) in the supply of those products

could negatively affect the timely delivery of DCSI’s products to customers and future sales. Comtrak currently relies on a single source for a major portion of its products.

     Certain of the Company’s other businesses are dependent upon sole source or a limited number of third-party manufacturers of parts and components. Many of these suppliers are small businesses. Since alternative supply sources are limited, this increases the risk of adverse impacts on the Company’s production schedules and profits if the Company’s suppliers default in fulfilling their price, quality or delivery obligations.

MOST COMMUNICATIONS SEGMENT SALES ARE TO OR FOR THE UTILITY INDUSTRY, KNOWN FOR LONG SALES CYCLES AND UNCERTAINTY, WHICH COULD AFFECT THE TIMING OF REVENUE

     Most of the Communications segment’s sales are to or for the utility industry, where sales cycles are long and unpredictable. Most sales involve large dollar amounts, and are marked by extended and complex competitive procurements. These factors often cause delays in the timing of sales, and such delays could result in order postponement, reduction in size or cancellation, thereby reducing the Company’s future revenue.

PRODUCT DEFECTS COULD RESULT IN COSTLY FIXES, LITIGATION AND DAMAGES

     If there are claims related to defective products (under warranty or otherwise), particularly in a product recall situation, the Company could be faced with significant expenses in replacing or repairing the product. For example, the DCSI and Hexagram meter modules are installed in thousands of residences and other buildings. The replacement/repair costs for such problems could have a material adverse effect on the Company’s financial condition. In addition, if a dispute over product claims cannot be settled, arbitration or litigation may result, involving attorneys’ fees and the potential of damage awards.

INCREASES IN RAW MATERIAL PRICES AND AVAILABILITY OF RAW MATERIALS COULD ADVERSELY AFFECT THE COMPANY’S BUSINESS.

     The cost of raw materials is a major element of the total cost of many of the Company’s products. For example, Filtertek’s petroleum-based resins and the Test segment’s critical components rely on purchases of raw materials from third parties. Increases in the prices of raw materials (such as steel, copper, nickel, zinc, wood and petrochemical products) could have an adverse impact on business by, among other things, increasing costs and reducing margins.

     In addition, the Company’s reliance on sole or limited sources of supply of raw materials in each of its segments could adversely affect the business. For example, there are a limited number of suppliers of Filtertek’s petroleum-based raw materials. Certain refineries that produce these materials are concentrated in hurricane areas. Weather-created disruptions in supply, in addition to affecting costs, could impact the Company’s ability to procure an adequate supply of these raw materials and delay or prevent deliveries of products to customers. Also, many petroleum supplies come from countries with unstable political environments. Supplies of base petroleum could be impacted by events such as embargoes and regional conflicts.

CHANGES IN TEST STANDARDS COULD ADVERSELY IMPACT TEST SEGMENT SALES

     A significant portion of the Test segment’s business involves sales to technology customers, which results from these customers needing to meet specific international and domestic test standards. If demand for product testing from these customers decreases, the Company’s business could be adversely affected. Likewise, if regulatory agencies eliminate or reduce certain domestic or international test standards, the Company’s sales could be adversely affected. For example, if it were determined that there is no need to include Wi-Fi technology in mobile phones, there may be no need for certain testing on mobile phones. Also, if a regulatory authority relaxes the test standards for certain electronic devices because they do not interfere with the broadcast spectrum, sales of certain Test products could be reduced.

DIMINISHING MARKET SHARE OF AUTOMOTIVE CUSTOMERS COULD AFFECT FILTRATION/FLUID FLOW SEGMENT SALES.

     Filtertek relies heavily on sales of its products for use in the North American automotive industry. The North American automotive manufacturers are losing market share to foreign competition, most of which do not currently use Filtertek products. This loss of market share could reduce the number of products that Filtertek will sell.

ECONOMIC, POLITICAL AND OTHER RISKS OF THE COMPANY’S INTERNATIONAL OPERATIONS COULD ADVERSELY AFFECT BUSINESS

     In fiscal 2006, approximately 22% of the Company’s sales were made to international customers. An economic downturn or an adverse change in the political situation in certain foreign countries in which the Company does business could cause a decline in revenues and adversely affect the Company’s financial condition. For example, the Test segment does significant business in Asia. Changes in the Asian political climate or political changes in specific Asian countries could negatively affect the Company’s business. Filtertek has significant operations in Europe. Softness in the European economy could have a significant adverse effect on the Company’s European revenues, which represented approximately 9% of the Company’s total revenues in fiscal 2006.

     The Company’s international sales are also subject to other risks inherent in foreign commerce, including currency fluctuations and devaluations, the risk of war and terrorism, differences in foreign laws, uncertainties as to enforcement of contract rights, and difficulties in negotiating and resolving disputes with foreign customers.

SALES OF GOVERNMENT PRODUCTS DEPEND UPON CONTINUED GOVERNMENT FUNDING.

     During the past three years, from 6% to 8% of the Company’s revenues has been generated from sales to the U.S. Government or its contractors. These sales are dependent on continuous government funding of its programs. There could be reductions or terminations of the government funding on programs which are applicable to the Company or its customers. These funding effects could severely affect the Company’s sales and profit, and could bring about a major restructuring of Company operations, which could result in an adverse effect on its financial results.

     For example, a significant part of VACCO’s sales involve major government defense and space programs. Government reduction in spending on these programs could have a significant adverse impact on Company financial results.

THE END OF CUSTOMER PRODUCT LIFE CYCLES COULD NEGATIVELY AFFECT FILTRATION/FLUID FLOW SEGMENT RESULTS.

     Many of the Company’s filtration products are sold to be components in the customers’ end-products. If a customer discontinues a certain end-product line, the ability of the Company to continue to sell those components will be reduced or eliminated. The result could be a significant decrease in Company sales and revenue.

     For example, a substantial portion of PTI’s revenue is generated from commercial aviation aftermarket sales. As certain aircraft are retired and replaced by newer aircraft, there could be a corresponding decrease in sales and revenue associated with the Company’s current products. Such a decrease could adversely affect the Company’s operating results. In addition, if the Government cuts back the space program, VACCO’s sales of space products would be reduced, and its revenues could be adversely affected. Further, if the market for large motor vehicles softens, the demand for Filtertek’s automotive products will decline, which may cause an impact on revenues.

DISPUTES WITH CONTRACTORS COULD ADVERSELY AFFECT THE TEST SEGMENT’S COSTS.

     A major portion of the Test segment’s business involves working in conjunction with contractors to produce the end-product, such as an electronic test chamber. If there are performance problems caused by either the Company or a contractor, these often result in cost overruns and may lead to a dispute as to which

party is responsible. The resolution of such disputes can result in arbitration or litigation, and could involve significant expense including attorneys’ fees. In addition, these disputes may result in reduction in revenue or even a loss to the Company on a particular project.

ACQUISITIONS OF OTHER COMPANIES CARRY RISK.

     Acquisitions of other companies involve numerous risks, including difficulties in the integration of the operations, technologies and products of the acquired companies, the potential exposure to unanticipated and undisclosed liabilities, the potential that expected benefits or synergies are not realized and that operating costs increase, the potential loss of key personnel, suppliers or customers of acquired businesses and the diversion of management’s time and attention from other business concerns. Although management will attempt to evaluate the risks inherent in any particular transaction, no assurances can be made that the Company will properly ascertain all such risks.

DESPITE ITS EFFORTS, THE COMPANY MAY BE UNABLE TO ADEQUATELY PROTECT ITS INTELLECTUAL PROPERTY.

     Despite the Company’s efforts to protect its intellectual property, unauthorized parties or competitors may copy or otherwise obtain and use the Company’s products and technology, particularly in foreign countries where the laws may not protect the Company’s proprietary rights as fully as in the United States. Current and future actions to enforce the Company’s proprietary rights may result in substantial costs and diversion of resources. No assurances can be made that any such actions will be successful. In addition, the Company may not elect to pursue an unauthorized user due to the high costs and uncertainties associated with litigation. The Company may also face exposure to claims by others challenging its intellectual property rights.

CHANGES IN ENVIRONMENTAL OR REGULATORY REQUIREMENTS COULD INCREASE EXPENSES AND ADVERSELY AFFECT PROFITABILITY.

     The Company’s operations and properties are subject to U.S. and foreign environmental laws and regulations governing, among other things, the generation, storage, emission, discharge, transportation, treatment and disposal of hazardous materials and the clean up of contaminated properties. Changes in such requirements could increase the cost of compliance. Failure to comply could result in the imposition of significant fines, suspension of production, alteration of product processes, cessation of operations or other actions, which could materially and adversely affect the Company’s business, financial condition and results of operations.

COMPETITION IS BROADLY BASED AND GLOBAL IN SCOPE.

     The Company faces competition from a large number of manufacturers and distributors for nearly all of its products. Some of the Company’s competitors are larger, more diversified corporations with greater financial, marketing, production and research and development resources. If the Company cannot compete successfully against current or future competitors, it could have a material adverse effect on the Company’s business, financial condition and results of operations.

Item 3. Legal Proceedings

As a normal incident of the businesses in which the Company is engaged, various claims, charges and litigation are asserted or commenced from time to time against the Company. Lindgren is arbitrating a contract dispute with a prime contractor involving the assertion of certain construction delay damages of approximately $3.7 million. The project was completed in 2005. Lindgren vigorously denies responsibility for this delay and for these damages, and has asserted a claim against the prime contractor of $0.9 million based on damages suffered by Lindgren. Lindgren continues to aggressively defend its position and pursue its right to affirmative damages; however, there can be no assurance of the outcome at this time. With respect to claims and litigation asserted or commenced against the Company, it is the opinion of management, that final judgments, if any, which might be rendered against the Company are adequately reserved, covered by insurance and are not likely to have a material adverse effect on its financial condition or results of operation
