Note1. Basis of Presentation

The accompanying condensed consolidated financial statements of AXT, Inc., a Delaware corporation (“AXT,” the “Company,” “we,” “us,” and “our” refer to AXT, Inc. and all of its consolidated subsidiaries) are unaudited, and have been prepared in accordance with accounting principles generally accepted in the United States of America (“U.S. GAAP”) for interim financial information and with the instructions to Form10-Q and Article10 of Regulation S-X. Accordingly, this interim quarterly financial report doesnot include all disclosures required by U.S. GAAP for complete consolidated financial statements. In the opinion of our management, the unaudited condensed consolidated financial statements reflect all adjustments, consisting only of normal recurring adjustments, considered necessary to present fairly the financial position, results of operations and cash flows of the Company for all periods presented.

Our management has made a number of estimates and assumptions relating to the reporting of assets and liabilities and the disclosure of contingent assets and liabilities to prepare these condensed consolidated financial statements in conformity with U.S. GAAP. Such estimates and assumptions are based on historical experience, known trends and events and various other factors that management believes to be reasonable under the circumstances. These estimates and assumptions* may*change as new events occur and additional information is obtained. Actual results could differ materially from those estimates.

The results of operations for thethree andsix months ended* June 30, 2026* arenot necessarily indicative of the results to be expected in the future or for the full fiscal year. It is recommended that these condensed consolidated financial statements be read in conjunction with our audited consolidated financial statements and the notes thereto included in our Annual Report on Form10-K for the year ended* December 31, 2025* filed with the Securities and Exchange Commission (the “SEC”) on* March 17,*2026.

The condensed consolidated financial statements include the accounts of AXT and our consolidated subsidiaries, Beijing Tongmei Xtal Technology Co., Ltd. (“Tongmei”), AXT-Tongmei, Inc. (“AXT-Tongmei”), Baoding Tongmei Xtal Technology Co., Ltd. (“Baoding Tongmei”), ChaoYang Tongmei Xtal Technology Co., Ltd. (“ChaoYang Tongmei”), ChaoYang LiMei Semiconductor Technology Co., Ltd. (“ChaoYang LiMei”), ChaoYang XinMei High Purity Semiconductor Materials Co., Ltd. (“ChaoYang XinMei”), Nanjing JinMei Gallium Co., Ltd. (“JinMei”), ChaoYang JinMei Gallium Ltd. (“ChaoYang JinMei”), ChaoYang ShuoMei High Purity Semiconductor Materials Co., Ltd. (“ChaoYang ShuoMei”), MaAnShan JinMei Gallium Ltd., (“MaAnShan JinMei”) and Beijing BoYu Semiconductor Vessel Craftwork Technology Co., Ltd. (“BoYu”). All significant inter‑company accounts and transactions have been eliminated. Investments in business entities in which we donot have controlling interests, but have the ability to exercise significant influence over operating and financial policies (generally20-50% ownership), are accounted for by the equity method. As of* June 30, 2026* and* December 31, 2025*, we havethree companies accounted for by the equity method. For the majority-owned subsidiaries that we consolidate, we reflect the portion we donot own as either noncontrolling interests in stockholder’s equity or as redeemable noncontrolling interests in temporary equity on our condensed consolidated balance sheets and in our condensed consolidated statements of operations.

There have beenno material changes to the Company’s basis of consolidation, significant accounting policies, or the composition of its consolidated subsidiaries and equity method investments from those disclosed in the Company’s Annual Report on Form10-K for the year ended* December 31, 2025*.

Note2. Investments and Fair Value Measurements

Our investments consist of instruments with original maturities of more thanthree months. As of* June 30, 2026* and* December 31, 2025*, our cash, restricted cash, cash equivalents and debt investments are classified as follows (in thousands):

We manage our debt investments as a portfolio of highly marketable securities available to support our liquidity and capital needs. Although long-term investments* maybe sold before maturity, as of June 30, 2026*, we didnot intend to sell those investments within the nexttwelve months.

8

The following table summarizes the fair value and gross unrealized losses of available-for-sale debt securities, aggregated by investment category and length of time in a continuous unrealized loss position, as of* June 30, 2026* (in thousands):

We review our debt investment portfolio at least quarterly, or when there are changes in credit risks or other potential valuation concerns. As of* June 30, 2026*, we determined that the unrealized losses were attributable to changes in market interest rates rather than credit deterioration; accordingly,no allowance for credit losses was recorded.

Restricted Cash

We maintain restricted cash in connection with cash balances temporarily restricted for regular business operations. These balances have been excluded from the Company’s cash balance. As of* June 30, 2026* and* December 31, 2025*, $33.1 million and $8.1 million were included in restricted cash in our condensed consolidated balance sheets, respectively. The increase in restricted cash was primarily attributable to additional deposits pledged as collateral in connection with borrowings by the Company’s subsidiaries from PRC banks.

Investments in Privately-held Raw Material Companies

We have made strategic investments in private companies located in China in order to gain access at a competitive cost to raw materials that are critical to our substrate business (see Note7). The investment balances for the non-consolidated companies are accounted for under the equity method, included in “Other assets” in the condensed consolidated balance sheets, totaled $14.1 million and $15.0 million as of* June 30, 2026* and* December 31, 2025*, respectively. As of* June 30, 2026*, there were three companies accounted for under the equity method. There wereno impairment charges for these investments during thethree andsix months ended* June 30, 2026and2025*.

Fair Value Measurements

We invest primarily in certificates of deposits, corporate bonds and notes, government securities and money market accounts. We review our debt investment portfolio for credit loss at least quarterly or when there are changes in credit risk or other potential valuation concerns. We believe it is probable the principal and interest will be collected in accordance with the contractual terms, and the unrealized loss on these securities was due to normal market fluctuations, andnot due to increased credit risk or other valuation concerns. ASC820, Fair Value Measurements and Disclosures, establishesthree levels of inputs that* maybe used to measure fair value. Level1* instrument valuations are obtained from real-time quotes for transactions in active exchange markets of the asset or identical assets. Level2 instrument valuations are obtained from readily- available, observable pricing sources for comparable instruments. Level3 instrument valuations are obtained from unobservable inputs in which there is little orno market data, which require us to develop our own assumptions. On a recurring basis, we measure certain financial assets and liabilities at fair value, primarily consisting of our short-term and long-term debt investments.

9

The type of instrument valued based on quoted market prices in active markets includes our money market funds, which are generally classified within Level1 of the fair value hierarchy. We classify our available-for-sale debt securities, including certificates of deposit and corporate bonds, as having Level2 inputs. The valuation techniques used to measure the fair value of these financial instruments having Level2 inputs were derived from bank statements, quoted market prices, broker or dealer statements or quotations, or alternative pricing sources with reasonable levels of price transparency.

We place short-term foreign currency hedges that are intended to offset the potential cash exposure related to fluctuations in the exchange rate between the United States dollar and Japanese yen. We measure the fair value of these foreign currency hedges at each month end and quarter end using current exchange rates and in accordance with U.S. GAAP. At quarter end, any foreign currency hedgesnot settled are netted in “Accrued liabilities” on the condensed consolidated balance sheets and classified as Level3 assets and liabilities. As of* June 30, 2026*, the net change in fair value from the placement of the hedge to settlement at each month end during the quarter had a de minimis impact on the condensed consolidated results.

There wereno changes in valuation techniques or related inputs in thethree andsix months ended* June 30, 2026*. There have beenno transfers between fair value measurements levels during thethree andsix months ended* June 30, 2026*.

Items Measured at Fair Value on a Nonrecurring Basis

Certain assets that are subject to nonrecurring fair value measurements arenot included in the table above. These assets include investments in privately-held companies accounted for by the equity method (see Note7). We didnot record any other-than-temporary impairment charges for these investments during thethree andsix months ended* June 30, 2026and2025*, respectively.

Note6. Related Party Transactions

In* September 2021and October 2021,our consolidated subsidiary, ChaoYang XinMei, received funding from a minority investor of $0.9 million and $1.0 million, respectively. As of December 31, 2021,$1.9 million was included in short-term loan from noncontrolling interest in our condensed consolidated balance sheets. In December 2021and January 2022,the same subsidiary received funding from Tongmei of $1.4 million and $1.4 million, respectively. In January 2022,the China local government certified this additional funding in ChaoYang XinMei as an equity investment. As a result, noncontrolling interests increased $2.2 million and redeemable noncontrolling interests increased $0.2 million. Short-term loan from noncontrolling interest decreased to $0. In April 2022,Tongmei entered into the Capital Increase Agreement with minority investors to further invest approximately $4.5 million in ChaoYang XinMei. In April 2022and May 2022,ChaoYang XinMei received funding from Tongmei of $1.1 million and $0.8 million, respectively, as equity investments. In April 2022and May 2022,the minority investors invested $0.7 million and $0.6 million, respectively. As a result, noncontrolling interests increased $1.4 million and redeemable noncontrolling interests increased $0.1 million. In July 2022,*Tongmei and the minority investors further invested $0.8 million and $0.6 million in ChaoYang XinMei, respectively. This completed the investment obligations under the Capital Increase Agreement. As a result, noncontrolling interests increased $610,000 and redeemable noncontrolling interests increased $57,000. Tongmei’s ownership remained at 58.5% after these equity investments.

In* September 2022,our consolidated subsidiary, ChaoYang LiMei completed the sale of land and its attached buildings to our equity investment entity, ChaoYang KaiMei Quartz Co., Ltd.

Our Related Party Transactions Policy seeks to prohibit all conflicts of interest in transactions between related parties and us, unless they have been approved by our Board of Directors. This policy applies to all of our employees, directors, and our consolidated subsidiaries. Our executive officers retain board seats on the board of directors of the companies in which we have invested in our PRC joint ventures (see Note7).

Note7. Investments in Privately-Held Raw Material Companies

We have made strategic investments in private companies located in China in order to gain access at a competitive cost to raw materials that are critical to our substrate business. These companies form part of our overall supply chain strategy.

As of* June 30, 2026*, the investments are summarized below (in thousands):

• These percentages reflect the ownership currently in effect upon the completion of the reorganization in China and the ownership in effect upon the completion of the new capital funding by private equity investors in* January 2021.*

** As of* June 30, 2026*, Tongmei’s noncontrolling interests and redeemable noncontrolling interests totaled approximately 14.5%. AXT remains the controlling stakeholder of Tongmei and holds a majority of the Board of Director positions of Tongmei.

Although we have representation on the board of directors of each of the privately held raw material companies, the daily operations of each of these companies are managed by local management andnot by us. Decisions concerning their respective short-term strategy and operations, ordinary course of business capital expenditures and sales of finished product, are made by local management with regular guidance and input from us.

For AXT’s minority investment entities that arenot consolidated, the investment balances are included in “Other assets” in our condensed consolidated balance sheets and totaled $14.1 million and $15.0 million as of* June 30, 2026* and* December 31, 2025*, respectively. As of* June 30, 2026*, our ownership interests in ChaoYang KaiMei, Beijing JiYa Semiconductor Material Co., Ltd. ("JiYa"), and Xiaoyi XingAn Gallium Co., Ltd (“Xiaoyi XingAn”) were 40%,39%, and 25%, respectively. These minority investment entities arenot considered variable interest entities because:

In* April 2025,we received a $0.9 million dividend from JiYa. In May 2026,we received a dividend of $1.5 million from Xiaoyi XingAn and $0.5 million from JiYa. We haveno* current intentions to distribute to our investors earnings under our corporate structure. All of these distributions were paid to the PRC companies and the minority shareholders.

Stock Repurchase Program

On* October 27, 2014,our Board of Directors approved a stock repurchase program pursuant to which we mayrepurchase up to $5.0 million of our outstanding common stock. These repurchases can be made from time to time in the open market and are funded from our existing cash balances and cash generated from operations. During2015,* we repurchased approximately 908,000 shares at an average price of $2.52 per share for a total purchase price of approximately $2.3 million under the stock repurchase program. No shares were repurchased during2025, 2024 and2023 under this program. During thethree andsix months ended* June 30, 2026*, we didnot repurchase any shares under the approved stock repurchase program. As of* June 30, 2026*, approxim ately $2.7 million remained available for future repurchases under this program. Currently, we donot plan to repurchase additional shares.

Series A Preferred Stock

By the terms of the Series A preferred stock, so long as any shares of Series A preferred stock are outstanding, neither the Company nor any subsidiary of the Company shall redeem, repurchase or otherwise acquire any shares of common stock, unless all accrued dividends on the Series A preferred stock have been paid. During2013 and2015, we repurchased shares of our outstanding common stock. As of* December 31, 2015,the Series A preferred stock had cumulative dividends of $2.9 million and we included this amount in “Accrued liabilities” in our consolidated balance sheets. In the quarter ended June 30, 2026and2025*, we didnot repurchase any of our outstanding common stock. If we are required to pay the cumulative dividends on the Series A preferred stock, our cash and cash equivalents would be reduced. We account for the cumulative year-to-date dividends on the Series A preferred stock when calculating our earnings per share.

Note9. Stock-Based Compensation

We account for stock-based compensation in accordance with the provisions of ASC Topic718, Compensation-Stock Compensation(“ASC718”), which established accounting for stock-based awards exchanged for employee services. Stock-based compensation cost is measured at each grant date, based on the fair value of the award, and is recognized as expense over the employee’s requisite service period of the award. All of our stock compensation is accounted for as an equity instrument.

In* May 2015,our stockholders approved our2015* Equity Incentive Plan (the*“2015* Plan”). The2015 Plan is a replacement of the2007 Plan. The 399,562 share reserve of the2007 Plan became the reserve of the2015 Plan, together with 3,000,000 additional shares approved for issuance under the2015 Plan. In* May 2019,our stockholders approved 1,600,000 of additional shares for issuance under the2015* Plan. In* May 2021,our stockholders approved 3,600,000 of additional shares for issuance under the2015* Plan. In* May 2024,our stockholders approved an amendment to the2015* Plan to increase the number of shares reserved for issuance by an additional 3,600,000 shares. In* May 2025,our stockholders approved our2025* Equity Incentive Plan (the*“2025* Plan”). The2025 Plan is a replacement of the2015 Plan, which expired on* April 1, 2025.The2015* Plan will continue to govern the awards granted under that Plan. The 4,313,156 share reserve of the2015 Plan became the reserve of the2025 Plan. Awards that* maybe made under the2025* Plan are stock options, stock appreciation rights, restricted stock, restricted stock units, performance shares, performance units, deferred compensation awards and other stock-based awards. Stock options and stock appreciation rights awarded under the2025 Plan* maynot* be repriced without stockholder approval. Stock options and stock appreciation rights* maynot* be granted below fair market value. Stock options or stock appreciation rights generally shallnot be fully vested over a period of less than four years from the date of grant and cannot be exercised more than 10 years from the date of grant. Restricted stock, restricted stock units, and performance awards generally shallnot vest faster than over athree-year period (or atwelve-month period if vesting is based on a performance measure). However, options granted to consultants and restricted stock awards granted to independent board members typically vest inone year and the2025 Plan does allow for similar vesting to employees.

The following table summarizes compensation costs related to our stock-based awards (in thousands, except per share data):

We didnot capitalize any stock-based compensation to inventory as of* June 30, 2026* and* December 31, 2025* due to the immateriality of the amount.

16

We estimate the fair value of stock options using the Black-Scholes option pricing model, consistent with the provisions of ASC718. There wereno options granted in thethree andsix months ended* June 30, 2026and2025*.

The following table summarizes the stock option transactions during thesix months ended* June 30, 2026* (in thousands, except per share data):

The aggregate intrinsic value in the table above represents the total pretax intrinsic value, based on our closing priceof $72.08 on* June 30, 2026*, which would have been received by the option holder had all option holders exercised their options on that date.

Restricted stock awards

A summary of activity related to restricted stock awards for thesix months ended* June 30, 2026* is presented below (in thousands, except per share data):

As of* June 30, 2026*, the unamortized compensation costs related to unvested restricted stock awards was approximately $9.4 million, which is to be amortized on a straight-line basis over a weighted-average period of approximately 1.6 years.

At-Risk, Performance Shares

In* February 2025,the Company issued at-risk, performance shares classified as equity awards. Expense is recognized quarterly on a straight-line method over the requisite service period, based on the probability of achieving the specified financial performance metric, with changes in expectations recognized as an adjustment to earnings in the period of change. Compensation cost isnot* recognized for at-risk, performance shares that donot vest because service or performance conditions arenot satisfied and any previously recognized compensation cost is reversed. At-risk, performance shares are eligible to receive dividend equivalents under the Company’s2015 Equity Incentive Plan (the “Plan”), as determined by the Board of Directors. The Company will recognize forfeitures as they occur.

The Company’s at-risk, performance shares are classified as equity and contain performance and service conditions that must be satisfied for an employee to receive the shares. The financial performance metric for the at-risk, performance shares issued in* February 2025is based upon the Company’s year-end actual results in2025.* All performance shares, if earned, are still subject to annual vesting over afour-year period, except thatno shares are vested on thefirst anniversary because the performance measurement is based on year-end results for the year2024 and2025, respectively.

17

The fair value of the at-risk, performance shares is determined based on the closing price of the Company’s common stock on thefirst day after the public issuance of the Company’s earnings release for the most recent fiscal quarter, following the Compensation Committee and Board of Directors approval, which is considered the grant date. The fair value per share of the at-risk, performance shares classified as equity awards granted in* February 2025and February 2024*was $2.23 and $2.28, respectively.

On* February 20, 2024,the Compensation Committee recommended, and the Board approved, the grant to Dr. Morris Young of 223,590 at-risk, performance shares under the Plan. On February 20, 2024,the Compensation Committee approved the grant to Gary Fischer of 77,600 at-risk, performance shares under the Plan. If the minimum financial metric for fiscal year2024* is achieved, then based upon a performance formula, a corresponding portion of the 223,590 shares issued to Dr. Young would be eligible to vest and a corresponding portion of the 77,600 shares issued to Mr. Fischer would be eligible to vest. If the target financial metric is exceeded, then additional shares above the target number of shares are earned based on such performance formula and the maximum number of additional shares earned is capped at 100% of the target. If the minimum financial metric for fiscal year2024 isnot achieved, then these awards are forfeited. On* February 18, 2025,the Compensation Committee met and certified that the year-over-year annual revenue growth rate achieved for fiscal year2024,* expressed as a percentage, was 200%. Therefore, the maximum number of at-risk performance shares became eligible to vest.

On* February 18, 2025,the Compensation Committee recommended, and the Board approved, the grant to Dr. Morris Young of 223,590 at-risk, performance shares under the Plan. On February 18, 2025,the Compensation Committee approved the grant to Gary Fischer of 77,600 at-risk, performance shares under the Plan. If the minimum financial metric for fiscal year2025* is achieved, then based upon a performance formula, a corresponding portion of the 223,590 shares issued to Dr. Young would be eligible to vest and a corresponding portion of the 77,600 shares issued to Mr. Fischer would be eligible to vest. If the target financial metric is exceeded, then additional shares above the target number of shares are earned based on such performance formula and the maximum number of additional shares earned is capped at 100% of the target. If the minimum financial metric for fiscal year2025 isnot achieved, then these awards are forfeited. On* February 18, 2026,the Compensation Committee met and certified that the year-over-year annual revenue growth rate achieved for fiscal year2025,* expressed as a percentage, was 195.15%.

A summary of the status of our unvested at-risk, performance shares as of* June 30, 2026* is presented below (in thousands, except per share data):

As of* June 30, 2026*, there was $0.3 million of unrecognized compensation expense related to unvested at-risk, performance shares that is expected to be recognized over a weighted-average period of 1.2 years.

Note10. Net Income (Loss) Per Share

Basic net income (loss) per share is computed using the weighted-average number of common shares outstanding during the periods less shares of common stock subject to repurchase and non-vested stock awards. Diluted net income (loss) per share is computed using the weighted-average number of common shares outstanding and potentially dilutive common shares outstanding during the periods. The dilutive effect of outstanding stock options and restricted stock awards is reflected in diluted earnings per share by application of the treasury stock method. Potentially dilutive common shares consist of common shares issuable upon the exercise of stock options and vesting of restricted stock awards. Potentially dilutive common shares are excluded from the computation of weighted-average number of common shares outstanding in net loss years, as their effect would be anti-dilutive to the computation.

A reconciliation of the numerators and denominators of the basic and diluted net loss per share calculations is as follows (in thousands, except per share data):

The 883,000 shares of $0.001 par value Series A preferred stock issued and outstanding as of* June 30, 2026* and* December 31, 2025*, valued at $3,532,000, are non-voting and non-convertible preferred stock with a 5.0% cumulative annual dividend rate payable when declared by the Board of Directors and a $4 per share liquidation preference over common stock, which must be paid before any distribution is made to common stockholders. These preferred shares were issued to Lyte Optronics, Inc. stockholders in connection with the completion of our acquisition of Lyte Optronics, Inc. on* May**28,* 1999.

We have entered into indemnification agreements with our directors and officers that require us to indemnify our directors and officers against liabilities that* may*arise by reason of their status or service as directors or officers, other than liabilities arising from willful misconduct of a culpable nature; to advance their expenses incurred as a result of any proceeding against them as to which they could be indemnified; and to obtain directors’ and officers’ insurance if available on reasonable terms, which we currently have in place.

Product Warranty

We provide warranties for our products for a specific period of time, generally twelve months, against material defects. We provide for the estimated future costs of warranty obligations in cost of sales when the related revenue is recognized. The accrued warranty costs represent the best estimate at the time of sale of the total costs that we expect to incur to repair or replace product parts that fail while still under warranty. The amount of accrued estimated warranty costs is primarily based on historical experience as to product failures as well as current information on repair costs. On a quarterly basis, we review the accrued balances and update the historical warranty cost trends.

The following table reflects the change in our warranty accrual which is included in “Accrued liabilities” in the condensed consolidated balance sheets, during thethree andsix months ended* June 30, 2026and2025* (in thousands):

Contractual Obligations

In2020, we and a competitor entered into a cross license and covenant agreement (the “Cross License Agreement”), which has a term that began on* January 1, 2020and expires on December 31, 2029.The Cross License Agreement is a fixed-cost cross license andnot* a variable-cost cross license that is based on revenue or units. Under the Cross License Agreement, we are obligated to make annual payments over a 10-year period.

Land Purchase and Investment Agreement** **

We have established a wafer process production line in Dingxing, China. In addition to a land rights and building purchase agreement that we entered into with a private real estate development company to acquire our new manufacturing facility, we also entered into a cooperation agreement with the Dingxing local government. In addition to pledging its full support and cooperation, the Dingxing local government will issue certain credits or rebates to us as we achieve certain milestones. We, in turn, agreed to hire local workers over time, pay taxes when due and eventually demonstrate a total investment of approximately $90 million in value, assets and capital. The investment will include cash paid for the land and buildings, cash on deposit in our name at local banks, the gross value of new and used equipment (including future equipment that might be used for indium phosphide and germanium substrates production), the deemed value for our customer list or the end user of our substrates, for example, the end users of3-D sensing VCSELs (vertical cavity surface emitting lasers), a deemed value for employment of local citizens, a deemed value for our proprietary process technology, other intellectual property, other intangibles and additional items of value. There isno timeline or deadline by which this must be accomplished, rather it is a good faith covenant entered into between AXT and the Dingxing local government. Further, there isno specific penalty contemplated if either party breaches the agreement. However, the agreement does state that each party has a right to seek from the other party compensation for losses. Under certain conditions, the Dingxing local government* may*purchase the land and building at the appraised value. We believe that such cooperation agreements are normal, customary and usual in China and that the future valuation is flexible. We have a similar agreement with the city of Kazuo, China, although on a smaller scale. The total investment targeted by AXT in Kazuo is approximately $15 million in value, assets and capital. In addition, BoYu has a similar agreement with the city of Kazuo. The total investment targeted by BoYu in Kazuo is approximately $8 million in value, assets and capital.

Purchase Obligations with Penalties for Cancellation

In the normal course of business, we issue purchase orders to various suppliers. In certain cases, we* mayincur a penalty if we cancel the purchase order. As of June 30, 2026*, we donot have any outstanding purchase orders that will incur a penalty if cancelled by the Company.

Legal Proceedings

From time to time we* maybe involved in judicial or administrative proceedings concerning matters arising in the ordinary course of business. We donot* expect that any of these matters, individually or in the aggregate, will have a material adverse effect on our business, financial condition, cash flows or results of operations.

On* May 6, 2024,a putative shareholder class action complaint was filed in the U.S. District Court for the Eastern District of New York on behalf of persons or entities who purchased or acquired our publicly traded securities, against us, Morris S. Young, our Chief Executive Officer, and Gary L. Fischer, our Chief Financial Officer. The court transferred the case to the Northern District of California, where our headquarters are located. A lead plaintiff was appointed and an amended complaint was filed. The amended complaint asserts a putative class period from March 24, 2021to April 3, 2024,inclusive (the “Class Period”). The amended complaint alleges violations of Sections10*(b) and20(a) of the Securities Exchange Act of1934, as amended (the “Exchange Act”), and Rule10b-5 promulgated thereunder by the defendants, and seeks unspecified monetary relief, interest, and attorneys’ fees. On* May 28, 2025,the Court granted defendants’ motion to dismiss with leave to amend. Plaintiff filed hissecond* amended complaint on* June 27, 2025.Defendants responded with a motion to dismiss thesecond* amended complaint on* July 11, 2025.The Court granted defendants’ motion to dismiss plaintiff’ssecond* amended complaint on* July 7, 2026with leave to amend. On August 4, 2026,the plaintiff filed histhird* amended complaint.

On* August 22, 2024,a derivative lawsuit was filed in the Northern District of California by an alleged shareholder against Morris S. Young, our Chief Executive Officer, Gary L. Fischer, our Chief Financial Officer, then-serving directors David C. Chang, Jesse Chen, and Christine Russell, and former director Leonard J. LeBlanc, with the Company named as a nominal defendant (together, “Defendants”). Defendants moved to dismiss on November 6, 2024,following which the plaintiff filed an amended complaint on November 20, 2024.The amended complaint asserted that the defendants breached their fiduciary duties to the Company based on the allegations asserted in the original complaint in the putative shareholder class action. On November 27, 2024,defendants again moved to dismiss. On March 17, 2025,the Court granted our motion to dismiss, holding that the plaintiff didnot* make a pre-suit demand on our Board of Directors and failed to plead with particularity facts sufficient to excuse the lack of a demand and also for failure to state a claim. On* April 11, 2025,the plaintiff filed a notice that he didnot* intend to further amend his complaint. The Court entered judgment on* April 14, 2025.On May 13, 2025,*the plaintiff appealed to the United States Court of Appeals for the Ninth Circuit. Plaintiff-Appellant’s appeal is fully briefed.

22

It isnot possible at this time to reasonably assess the final outcomes of these litigations or to reasonably estimate the possible loss or range of loss with respect to these litigations. We believe these claims to be meritless and intend to vigorously defend against them.

Note13. Other Income, Net

Other income, net for thethree months ended* June 30, 2026and2025*, includes a grant of $0.1 million and $0.2 million, respectively, from government agencies as awards for technological innovation and job creation. Other income (expense), net for thesix months ended* June 30, 2026* and2025, includes a grant of $0.3 million and $0.5 million, respectively, from government agencies as awards for technological innovation and job creation.

In addition, we incurred a foreign currency transaction exchange loss of $217,000 and a gain of $45,000 for thethree months ended* June 30, 2026and2025*, respectively. We incurred a foreign currency transaction exchange loss of $391,000 and a gain of $86,000 for thesix months ended* June 30, 2026* and2025, respectively.

Note14. Income Taxes

We account for income taxes in accordance with ASC Topic740, Income Taxes (“ASC740”), which requires that deferred tax assets and liabilities be recognized using enacted tax rates for the effect of temporary differences between the book and tax bases of recorded assets and liabilities. ASC740 also requires that deferred tax assets be reduced by a valuation allowance if it is more likely thannot that a portion of the deferred tax asset willnot be realized.

We provide for income taxes based upon the geographic composition of worldwide earnings and tax regulations governing each region, particularly China. The calculation of tax liabilities involves significant judgment in estimating the impact of uncertainties in the application of complex tax laws, particularly in foreign countries such as China.

We recognize interest and penalties related to uncertain tax positions in income tax expense. Income tax expense for thethree andsix months ended* June 30, 2026* includesno interest and penalties. As of* June 30, 2026*, we haveno accrued interest and penalties related to uncertain tax positions. We file income tax returns in the U.S. federal, various states and foreign jurisdictions. Currently, there isno tax audit in any of the jurisdictions and we donot expect there will be any significant change to this.

Provision for income taxes for thethree andsix months ended* June 30, 2026* was mostly related to our wholly owned China subsidiaries and our partially owned subsidiaries in China. Income taxes and certain state taxes, have been provided for our U.S. operations as most of the income in the U.S. had been fully offset by utilization of federal and state net operating loss carryforwards.

On* July 4, 2025,the President signed into law the “One Big Beautiful Bill Act” (the “Act”). Among other things, the Act makes permanent many provisions of the2017* Tax Cuts and Jobs Act (the “TCJA”) that otherwise would have expired this year. The Act permanently reinstates elective expensing for qualifying domestic research and experimental expenditures with respect to amounts paid or incurred after* December 31, 2024 (section174A*). Expenditures for research performed outside the U.S. remain amortizable over15 years. We capitalize the R&E expense incurred by our China subsidiaries and amortize it over15 years.

California Senate Bill167 was signed into law by the acting governor on* June 27, 2024.The bill makes several tax changes designed to alleviate the2024*-2025 budget. For tax years beginning on or after* January 1, 2024,and before January 1, 2027,net operating losses (NOLs) are suspended for both corporate and personal income taxes. The suspension willnot* apply to any taxpayer with net business income or modified adjusted income of less than*$1* million. Another provision in Senate Bill167 limits the use of credits for tax years beginning on or after* January 1, 2024,and before January 1, 2027.During this period, a business (including all taxpayers that are members of a combined report) mayclaim a total of only$5* million in credits under both the Corporation and Personal Income Tax laws (including the carryover of any business credit). Since the Company’s profit level is below*$1* million, Bill167 hasno impact on the Company.

Note15. Revenue

Revenue Recognition

We manufacture and sell high-performance compound semiconductor substrates including indium phosphide, gallium arsenide and germanium wafers, and our consolidated subsidiaries sell certain raw materials, including high purity gallium (7N Ga), pyrolytic boron nitride (pBN) crucibles and boron oxide (B2O3). After we ship our products, there areno remaining obligations or customer acceptance requirements that would preclude revenue recognition. Our products are typically sold pursuant to purchase orders placed by our customers, and our terms and conditions of sale donot require customer acceptance. We account for a contract with a customer when there is a legally enforceable contract, which could be the customer’s purchase order, the rights of the parties are identified, the contract has commercial terms, and collectibility of the contract consideration is probable. The majority of our contracts have a single performance obligation to transfer products and are short term in nature, usually less thansix months; however, we have recently entered into several long-term arrangements with customers. Our revenue is measured based on the consideration specified in the contract with each customer in exchange for transferring products that are generally based upon a negotiated formula, list or fixed price. Revenue is recognized when control of the promised goods is transferred to our customer, which is either upon shipment from our dock, receipt at the customer’s dock, or removal from consignment inventory at the customer’s location, in an amount that reflects the consideration we expect to be entitled to receive in exchange for those goods.

We have elected to account for shipping and handling as activities to fulfill the promise to transfer the goods. Shipping and handling fees billed to customers in a sales transaction are recorded as an offset to shipping and handling expenses. Sales taxes and value added taxes in foreign jurisdictions that are collected from customers and remitted to governmental authorities are accounted for on a net basis and, therefore, are excluded from revenue.

We donot provide training, installation or commissioning services. We provide for future returns based on historical data, prior experience, current economic trends and changes in customer demand at the time revenue is recognized. We donot recognize any asset associated with the incremental cost of obtaining revenue generating customer contracts. As such, sales commissions are expensed as incurred, given that the expected period of benefit is less thanone year.

Contract Balances

Contract assets are recorded when we have a conditional right to consideration for our completed performance under the contracts. Accounts receivables are recorded when the right to this consideration becomes unconditional. We believe the fair value of our accounts receivable approximates its carrying value due to its short maturities and nominal credit risk. We donot have any material contract assets as of* June 30, 2026*. In some contracts we require payment in advance of shipment, per a billing schedule reflected in our customer contracts, and the payment is recorded as a contract liability.

As of* June 30, 2026,the aggregate transaction price allocated to the remaining performance obligations under the long-term supply agreements was approximately $98.5 million, excluding applicable taxes. We expect to recognize this amount as revenue through thefirst* half of2029 as the related products are delivered and control transfers to customers. The agreements require aggregate contractual advance payments of approximately $47.7 million, of which approximately $12.7 million had been received as of* June 30, 2026*.

The following table reflects the current portion of contract liabilities, which is included in “Accrued liabilities” on the condensed consolidated balance sheets, as of* June 30, 2026* and* December 31, 2025* (in thousands):

During thethree andsix months ended* June 30, 2026*, the Company recogn ized $1,000 and $29,000, respectively, of revenue that was included in the contract balances as of* December 31,2025. During thethree andsix months ended June 30, 2025*, the Company recognized $28,000 and $1.6 million, respectively, of revenue that was included in the contract balances as of* December 31,*2024.

As of* June 30, 2026*, approximately $1.9 million of contract liabilities was classified as long-term and included in "Other long-term liabilities" on the condensed consolidated balance sheets. There wereno long-term contract liabilities as of* December 31, 2025*.

Disaggregated Revenue

In general, revenue disaggregated by product types and geography (see Note11) is aligned according to the nature and economic characteristics of our business and provides meaningful disaggregation of our results of operations. Since we operate inone segment, all financial segment and product line information can be found in the condensed consolidated financial statements.

Note16. Loans and Line of Credit

Short-term Loans

Our bank loans and credit facilities are primarily entered into by our subsidiaries with various PRC banks and generally have original maturities of12 months or less. These borrowings are classified as “Short-term loans” in our condensed consolidated balance sheets.

As of* June 30, 2026*, the outstanding balance of short-term loans was $79.0 million, with interest rates ranging from 2.0% to 3.8%. Of this amount, $49.2 million was unsecured, $21.8 million was secured by the time deposit of the Company, and $8.0 million was secured by real estate properties owned by certain subsidiaries. As of* December 31, 2025*, the outstanding balance of short-term loans was $58.6 million, with interest rates ranging from 2.2% to 3.9%. Of this amount, $43.0 million was unsecured, $7.4 million was secured by the time deposit of the Company, and $8.2 million was secured by real estate properties owned by certain subsidiaries. Time deposit pledged as collateral is classified as restricted cash and presented separately in the condensed consolidated balance sheets.

Long-term Loans

On* January 30, 2024,one of our consolidated subsidiaries secured a new line of credit amounting to $9.7 million, structured as afive-year bank loan. The credit facility bears interest at a rate of 6.5% per annum on the amount drawn from the line of credit. The credit facility is collateralized by the real estate properties owned by the subsidiary. In January 2024,the subsidiary borrowed $5.8 million against the credit facility. The intended use of the credit facility is for construction projects. As of June 30, 2026*, $4.4 million is included in “Other long-term liabilities” and $0.9 million is included in “Short-term loans” in our condensed consolidated balance sheets.

In* December 2023and February 2026,two of our consolidated subsidiaries entered into financing arrangements with unrelated financing companies, receiving proceeds of approximately $2.1 million and $2.9 million, respectively. Upon the maturity of the December 2023arrangement, the subsidiary entered into another financing arrangement in June 2026and obtained financing in the form of notes receivable with a face value of approximately $1.9 million. According to the agreements, the subsidiaries temporarily transferred ownership of its production lines and related equipment to the financing companies, while retaining the right to use the properties in their operations. The February 2026and June 2026arrangements each have a term of 36 months and provide the subsidiaries with options to repurchase the production lines and related equipment at the end of the respective terms for nominal consideration of approximately $14.00 per arrangement. As of June 30, 2026*, $1.3 million is included in “Other long-term liabilities” and $3.3 million is included in “Short-term loans” in our condensed consolidated balance sheets.

In* Septemberand November 2025,one of our consolidated subsidiaries entered into afour-year bank loan totaling $0.7 million at an interest rate of 3.1%. The loan is secured by the real estate properties owned byone of our consolidated subsidiaries. As of June 30, 2026*, $0.4 million is included in “Other long-term liabilities” and $0.2 million is included in “Short-term loans” in our condensed consolidated balance sheets.

25

In* Apriland June 2026,one of our consolidated subsidiaries entered into unsecured bank loan agreements with terms of 19 months and 14 months, respectively, and received aggregate proceeds of approximately $2.9 million at an interest rate of 2.5%. As of June 30, 2026*, $2.9 million is included in “Other long-term liabilities” and $0.06 million is included in “Short-term loans” in our condensed consolidated balance sheets.

In* Apriland May 2026,one of our consolidated subsidiaries entered intotwo bank loan agreements, each with a term of 24 months and secured by the time deposit of the Company, and received aggregate proceeds of approximately $7.1 million at an interest rate of 2.4%. As of June 30, 2026*, $6.4 million is included in “Other long-term liabilities” and $0.7 million is included in “Short-term loans” in our condensed consolidated balance sheets.

As of* June 30, 2026*, the maturities of our long-term loan liabilities infive years (including current portion) are as follows (in thousands):

In summary, short-term loans of $84.2 million included under “Short-term loans” in our condensed consolidated balance sheet at* June 30, 2026*, consisted of $79.0 million of short-term bank loans and $5.2 million of the current portion of long-term debt. Long-term loan of $15.5 million included under “Other long-term liabilities” in our condensed consolidated balance sheet at* June 30, 2026*. These borrowings are subject to customary lending arrangements. As of* June 30, 2026*, the Company was in compliance with all applicable covenants.

26

Note17. Leases

We lease certain equipment, office space, warehouse and facilities under long-term operating leases expiring at various dates through* November 2029.The majority of our lease obligations relate to our lease agreement for our facility in Fremont, California with approximately 19,467 square feet, which was scheduled to expire in2020.* Under the terms of the facility lease agreement, in* May 2020,we were granted an extension to the term of the lease for an additional three years. Furthermore, in September 2023,we entered into another agreement to extend the lease for an additional five years, commencing December 2023.There areno variable lease payments, residual value guarantees or any restrictions or covenants imposed by the facility lease. The remaining lease obligations relate to a nitrogen system to be used during the manufacturing process for our facility in Dingxing, China. The equipment lease became effective in August 2019and will expire in July 2029.The facility, located in Tongzhou, China, has a lease effective from December 2024and expiring in November 2029.There areno variable lease payments, residual value guarantees or any restrictions or covenants imposed by the equipment lease. All other operating leases have a term of12* months or less.

Leases are classified as either finance leases or operating leases. A lease is classified as a finance lease if anyone of the following criteria are met: the lease transfers ownership of the asset by the end of the lease term, the lease contains an option to purchase the asset that is reasonably certain to be exercised, the lease term is for a major part of the remaining useful life of the asset or the present value of the lease payments equals or exceeds substantially all of the fair value of the asset. A lease is classified as an operating lease if it doesnot meet anyone of these criteria. All of our leases are classified as operating leases and substantially all of our operating leases are comprised of equipment and office space leases.None of our leases are classified as finance leases.

For all leases at the lease commencement date, a right-of-use asset and a lease liability are recognized. The right-of-use asset represents the right to use the leased asset for the lease term. The lease liability represents the present value of the lease payments under the lease.

The right-of-use asset is initially measured at cost, which primarily comprises the initial amount of the lease liability, plus any initial direct costs incurred, consisting mainly of brokerage commissions, less any lease incentives received. All right-of-use assets are reviewed for impairment. The lease liability is initially measured at the present value of the lease payments, discounted using the interest rate implicit in the lease or, if that rate cannot be readily determined, our secured incremental borrowing rate for the same term as the underlying lease.

Lease payments included in the measurement of the lease liability comprise the following: the fixed noncancelable lease payments, payments for optional renewal periods where it is reasonably certain the renewal period will be exercised, and payments for early termination options unless it is reasonably certain the lease willnot be terminated early.

Lease expense for operating leases consists of the lease payments plus any initial direct costs, primarily brokerage commissions, and is recognized on a straight-line basis over the lease term.

We have electednot to recognize right-of-use assets and lease liabilities for short-term leases that have a term of12 months or less. The effect of short-term leases on our right-of-use asset and lease liability wasnot material.

As of* June 30, 2026*, the maturities of our operating lease liabilities (excluding short-term leases) are as follows (in thousands):

Note18. Redeemable Noncontrolling Interests

As discussed in Note1, during the quarter ended* December 31, 2020,Tongmei entered into the Capital Investment Agreements with Investors that invested approximately $48.1 million in the form of redeemable noncontrolling interests representing 7.06% of the outstanding shares of Tongmei. An additional investment of approximately $1.5 million of new capital was funded in early January 2021.Under China regulations these investments must be formally approved by the appropriate government agency and arenot* deemed to be dilutive until such approval is granted. The government approved the entire approximately $49 million investment on* January 25, 2021,at which time the Investors owned a redeemable noncontrolling interest in Tongmei of 7.28%. The initial carrying amount of the redeemable noncontrolling interest was recorded at fair value on the date of issuance of Tongmei’s common stock, net of issuance costs and presented in temporary equity on the condensed consolidated balance sheets. This classification is due to the existence of certain contingencies that could result in potential redemption at the fixed purchase price as described below. We currently donot* believe that this is probable thusno amortization of the issuance costs has been recorded.

Pursuant to the Capital Investment Agreements with the Investors, each Investor has the right to require AXT to redeem any or all Tongmei shares held by such Investor at the original purchase price paid by such Investor, without interest, in the event the IPO fails to pass the audit of the Shanghai Stock Exchange, isnot approved by the Chinese Securities Regulatory Commission (“CSRC”) or Tongmei cancels the IPO application. The aggregate redemption amount is approximately $49 million, subject to the foreign exchange rate variable at time of redemption.

Tongmei submitted its IPO application to the Shanghai Stock Exchange in* December 2021and it was formally accepted for review on January 10, 2022.The Shanghai Stock Exchange approved the IPO application on July 12, 2022.On August 1, 2022,the CSRC accepted for review Tongmei’s IPO application. On July 8, 2026,the STAR Market accepted Tongmei's withdrawal of its IPO application. The withdrawal gave rise to a redemption right: each Investor has the right, butnot* the obligation, to require us to redeem its investment, and we have the right, butnot the obligation, to redeem each Investor’s investment, in each case for a price equal to the original amount invested, without interest or any other return. Because the redemption price is fixed in RMB, the U.S. dollar amount payable will vary with the RMB/USD exchange rate. We are in discussions with each Investor to determine whether it wishes to continue its investment as Tongmei advances toward an application for a Hong Kong Stock Exchange listing, or to have its investment redeemed in whole or in part. We have sufficient funds to redeem the Investors' investments in full should full redemption be required.

The Update is effective for fiscal years beginning after* December 15, 2028,*and interim periods within those fiscal years. Adoption is expected to have an immaterial effect on our condensed consolidated financial statements.

In* May 2026,FASB issued ASU2026*-02, Environmental Credits and Environmental Credit Obligations (Topic818*), which provides guidance on the recognition, measurement, presentation and disclosure of environmental credits and related obligations. The Update is effective for fiscal years beginning after December 15, 2027,*including interim periods within those fiscal years, with early adoption permitted. Adoption is expected to have an immaterial effect on our condensed consolidated financial statements.

Note20. Subsequent Events

On* July 8, 2026,the STAR Market accepted Tongmei’s withdrawal of its IPO application, triggering redemption rights under the applicable Capital Investment Agreements. If all investors exercise their redemption rights in full, the aggregate redemption amount would be approximately $49 million. The withdrawal may*also result in the recognition of some or all of the deferred offering expenses associated with the STAR Market listing application and IPO.

On* July 23, 2026,the Company entered into an agreement with Beijing Bomeilian Special Ceramics Co., Ltd., a related party controlled by Dr. He, the general manager of BoYu, to acquire approximately 0.58% of Tongmei's outstanding shares for approximately $6 million. The transaction hadnot* closed as of the date these financial statements were issued.

On* July 26, 2026,we entered into asix-year capacity reservation agreement with a customer for the supply of InP wafer substrates. In consideration for the reserved product capacity, the customer agreed to pay ustwo deposits of $43.5 million each, which will be applied as shipment credits toward future purchases; the initial deposit is due within 30 business days after entry into the agreement, and the timing and terms of thesecond* deposit will be determined during2028.
