FREMONT, Calif., February 16, 2023 – AXT, Inc. (NasdaqGS: AXTI), a leading manufacturer of compound semiconductor substrates, today reported financial results for the fourth quarter and fiscal year, ended December 31, 2022.

Management Qualitative Comments

“2022 was a productive year in which we grew both our revenue and our profitability, and invested in innovations that pave the way for an exciting future,” said Morris Young, chief executive officer. “Though a softening of the macro environment has reset our growth trajectory, the trends that have driven our revenue, customer, and application expansion remain very much intact. We continue to see active development for technology advancement using our materials across consumer, communications infrastructure, data center, healthcare, automotive, and more. In addition, we have made significant progress this year in the development of next generation large diameter substrates for gallium arsenide and indium phosphide, which can enable a host of exciting new applications in our industry. As such, the fundamentals in our business are solid and we are looking ahead to our future with optimism.”

STAR Market Listing Update

On January 10, 2022, AXT announced that Beijing Tongmei Xtal Technology Co., Ltd. (“Tongmei”), its subsidiary in Beijing, China, submitted to the Shanghai Stock Exchange (the “SSE”) its application to list its shares in an initial public offering (the “IPO”) on the SSE’s Sci-Tech innovAtion boaRd (the “STAR Market”) and the application was accepted for review. Subsequently, Tongmei responded to several rounds of questions received from the SSE. On July 12, 2022, the SSE approved the listing of Tongmei’s shares in an IPO on the STAR Market. On August 1, 2022, the China Securities Regulatory Commission (the “CSRC”) accepted for review Tongmei’s IPO application. The STAR Market IPO remains subject to review and approval by the CSRC and other authorities. The process of going public on the STAR Market includes several periods of review and, therefore, is a lengthy process. Subject to review and approval by the CSRC and other authorities, Tongmei hopes to accomplish this goal in the coming months. AXT has posted a brief summary of the plan and the process on its website at http://www.axt.com.

Note Regarding Use of Non-GAAP Financial Measures

As discussed above, the company provides certain non-GAAP financial measures that exclude stock-based compensation in addition to, and not as a substitute for, or because it believes that such information is superior to, financial measures calculated in accordance with GAAP. The company believes that non-GAAP financial measures, when taken collectively, may be helpful to investors because they provide consistency and comparability with past financial performance and provide better comparability with our peer companies, many of which also use similar non-GAAP financial measures. Further, the company believes that these non-GAAP financial measures offer an important analytical tool to help investors understand the company’s core operating results and trends. In addition, management uses non-GAAP financial measures to compare the company’s performance relative to forecasts and strategic plans and to benchmark its performance externally against peer companies. However, non-GAAP financial information is presented for supplemental informational purposes only, has limitations as an analytical tool and should not be considered in isolation or as a substitute for financial information presented in accordance with GAAP. In addition, other companies may calculate similarly-titled non-GAAP financial measures differently or may use other measures to evaluate their performance, all of which could reduce the usefulness of the company’s non-GAAP financial measures as tools for comparison. The company encourages investors to carefully consider its results under GAAP, as well as its supplemental non‐GAAP information and the reconciliation between these presentations, to more fully understand its business. A reconciliation of our GAAP consolidated financial statements to our non-GAAP consolidated financial statements is provided below.

Forward-Looking Statements

The foregoing paragraphs contain forward-looking statements within the meaning of the Federal securities laws, including, for example, statements regarding the timing and completion of the proposed listing of shares of Tongmei on the STAR Market. Additional examples of forward-looking statements include statements regarding the market demand for our products, our growth prospects and opportunities for continued business expansion, including technology trends and new applications, our market opportunity, our ability to lead our industry, our relocation and our expectations with respect to our business prospects and financial results,including our gross margin performance, and our development of larger diameter substrates that we believe will enable the next generation of technology innovation across a number of end-markets. These forward-looking statements are based upon assumptions that are subject to uncertainties and factors relating to the company’s operations and business environment, which could cause actual results to differ materially from those expressed or implied in the forward-looking statements contained in the foregoing discussion. These uncertainties and factors include but are not limited to: the withdrawal, cancellations or requests for redemptions by private equity funds in China of investments in Tongmei, the administrative challenges in satisfying the requirements of various government agencies in China in connection with the investments in Tongmei and the listing of shares of Tongmei on the STAR Market, continued open access to companies to list shares on the STAR

Additional uncertainties and factors include, but are not limited to: the timing and receipt of significant orders; the cancellation of orders and return of product; emerging applications using chips or devices fabricated on our substrates; end-user acceptance of products containing chips or devices fabricated on our substrates; our ability to bring new products to market; product announcements by our competitors; the ability to control costs and improve efficiency; the ability to utilize our manufacturing capacity; product yields and their impact on gross margins; the relocation of manufacturing lines and ramping of production; possible factory shutdowns as a result of air pollution in China or COVID-19; COVID-19 or other outbreaks of a contagious disease; tariffs and other trade war issues; the financial performance of our partially owned supply chain companies; policies and regulations in China; and other factors as set forth in the company’s Annual Report on Form 10-K, quarterly reports on Form 10-Q and other filings made with the Securities and Exchange Commission. Each of these factors is difficult to predict and many are beyond the company’s control.
