Commenting on Align's Q4'23 and 2023 results, Align Technology President and CEO Joe Hogan said, “I am pleased to report fourth quarter results with better-than-expected revenues and earnings, primarily reflecting a sequential increase in clear aligner volume for adults and non-comprehensive cases, growth in Canada and the EMEA region, as well as increased revenues from systems and services. Fourth quarter revenues were up year-over-year primarily reflecting an increase in clear aligner volumes for teens and Invisalign DSP touch-up cases, as well as growth in the EMEA and APAC regions. For fiscal 2023, total revenues were up year over year, and we delivered fiscal 2023 non-GAAP operating margin above 21%, as expected. As of Q4, we achieved 17 million Invisalign® patients—including 4.7 million teens, as well as 4 million Vivera™ retainer cases, and over 100 thousand iTero™ scanners sold."

Hogan continued by announcing the launch of the company's latest iTero Lumina scanner, "Today, I’m excited to unveil a breakthrough technology — the iTero Lumina™ intraoral scanner - with 3X wider field of capture in a 50% smaller wand that delivers faster scanning, higher accuracy, and superior visualization for greater practice efficiency. iTero Lumina quickly, easily, and accurately captures more data while delivering exceptional scan quality and photorealistic visuals that remove the need for intraoral photos altogether. Doctors can now scan at twice the speed with a wide field of capture, multi angled scanning, and a large capture distance, meaning they can capture more dentition in greater detail throughout the scanning process. Align has filed over 30 patent applications covering technology related to the iTero Lumina intraoral scanner. I believe iTero Lumina has the potential to set a new standard of care for dental practices by simplifying the scanning of complex oral regions, while offering superior chair-side visualization and a more comfortable experience for patients, especially kids.”

Fiscal 2024 Business Outlook

Turning to our outlook, assuming no circumstances occur beyond our control, we provide the following framework for Q1 and fiscal 2024:

First quarter 2024 outlook:

• For Q1’24, we expect our worldwide revenues to be in the range of $960M to $980M, up slightly from Q4’23.
• We expect clear aligner volume and ASPs to be up slightly sequentially.
• We expect systems and services revenue to be down slightly sequentially, although less than the historical seasonal decline given the launch of the iTero Lumina™ for ortho workflows in Q1’24.
• We expect our Q1’24 GAAP operating margin and non-GAAP operating margin to be slightly above Q1’23 GAAP operating margin and non-GAAP operating margin, respectively.

Full year 2024 outlook:

• We expect our 2024 total revenues to be up mid-single digits over 2023.
• We expect our 2024 clear aligner and systems and services revenues to grow year over year in the same approximate range as 2024 total revenues.
• We expect our 2024 clear aligner ASPs to be up slightly year-over-year, primarily due to price increases and favorable foreign exchange, partially offset by a higher mix of non-comprehensive products which have lower ASPs.
• We expect our full year 2024 GAAP operating margin and non-GAAP operating margin to be slightly above the 2023 GAAP operating margin and non-GAAP operating margin, respectively.
• For 2024, we expect investments in capital expenditures to be approximately $100M. Capital expenditures are expected to primarily relate to building construction and improvements as well as manufacturing capacity in support of our continued expansion.

About Non-GAAP Financial Measures

To supplement our condensed consolidated financial statements, which are prepared and presented in accordance with generally accepted accounting principles in the United States ("GAAP"), we may provide investors with certain non-GAAP financial measures which may include constant currency net revenues, constant currency gross profit, constant currency gross margin, constant currency income from operations, constant currency operating margin, gross profit, gross margin, operating expenses, income from operations, operating margin, interest income and other income (expense), net, net income before provision for income taxes, provision for income taxes, effective tax rate, net income and/or diluted net income per share, which excludes certain items that may not be indicative of our fundamental operating performance including, foreign currency exchange rate impacts and discrete cash and non-cash charges or gains that are included in the most directly comparable GAAP measure. In Q4'22, we changed to a long-term non-GAAP effective tax rate in our computation of the non-GAAP income tax provision to provide better consistency across reporting periods. Our previous methodology for calculating our non-GAAP effective tax rate included certain non-recurring and period-specific items, that produced fluctuating effective tax rates that management does not believe are reflective of the Company's long-term effective tax rate. We have given effect to this new methodology effective January 1, 2022. Unless otherwise indicated, when we refer to non-GAAP financial measures they will exclude the effects of stock-based compensation, amortization of certain acquired intangibles, restructuring and other charges, acquisition-related costs, and associated tax impacts.

Our management believes that the use of certain non-GAAP financial measures provides meaningful supplemental information regarding our recurring core operating performance. We believe that both management and investors benefit from referring to these non-GAAP financial measures in assessing our performance and when planning, forecasting, and analyzing future periods. We believe these non-GAAP financial measures are useful to investors both because (1) they allow for greater transparency with respect to key metrics used by management in its financial and operational decision-making and (2) they are used by our institutional investors and the analyst community to help them analyze the performance of our business.

There are limitations to using non-GAAP financial measures as they are not prepared in accordance with GAAP and may be different from non-GAAP financial measures used by other companies. The non-GAAP financial measures are limited in value because they exclude certain items that may have a material impact upon our reported financial results. In addition, they are subject to inherent limitations as they reflect the exercise of judgments by management about which charges are excluded from the non-GAAP financial measures. We compensate for these limitations by analyzing current and future results on a GAAP as well as a non-GAAP basis and also by providing GAAP measures in our public disclosures. The presentation of non-GAAP financial information is meant to be considered in addition to, not as a substitute for or in isolation from, the directly comparable financial measures prepared in accordance with GAAP. We urge investors to review the reconciliation of our GAAP financial measures to the comparable non-GAAP financial measures included herein and not to rely on any single financial measure to evaluate our business. For more information on these non-GAAP financial measures, please see the tables captioned "Unaudited GAAP to Non-GAAP Reconciliation."
