Current report

There was a $145,000 impairment charge related to an investment during the three and six months ended June 30, 2025 and no impairment charge during the six months ended June 30, 2024.

Current report

On July 11, 2025, Ms. Christine Russell, our independent director, Chair of the Audit Committee, member of the Compensation Committee and the Nominating and Corporate Governance Committee, passed away. On July 14, 2025, we notified The Nasdaq Stock Market LLC (“Nasdaq”) that due to the passing of Ms. Russell, our Audit Committee has been reduced to two independent directors, and we are currently not compliant with Nasdaq Lising Rule 5605(c)(2)(A), which requires the Audit Committee to be comprised of a minimum of three independent directors. On July 18, 2025, Nasdaq confirmed our non-compliance and further notified us that, consistent with Nasdaq Listing Rule 5605(c)(4), Nasdaq will provide us a cure period to regain compliance (i) until the earlier of the Company’s next annual meeting of shareholders or July 11, 2026; or, (ii) if the next annual meeting of shareholders is held before January 7, 2026, then we must provide evidence of compliance no later than January 7, 2026. We intend to regain compliance as soon as possible and the Board will add a new independent director who satisfies the applicable requirements of the Nasdaq Listing Rules prior to the expiration of the foregoing cure period.

Current report

On July 29, 2025, we appointed Leonard J. Leblanc to the Board of Directors (the “Board”) to fill the vacancy on the Board due to the passing of Ms. Russell. Mr. Leblanc will serve as a Class III director with a maximum term expiring on July 29, 2027, or until his successor is duly elected and qualified. In connection with Mr. Leblanc’s appointment to the Board, the Board considered the compensation Mr. Leblanc previously received during his term as director emeritus, and determined that Mr. Leblanc is not independent under the Nasdaq Listing Rules as his total compensation exceeded $120,000 during January 1, 2022 to December 31, 2022. From January 1, 2023 to December 31, 2023, Mr. Leblanc’s total compensation did not exceed $120,00 and Mr. Leblanc did not receive any further compensation from us after December 29, 2023. As such, after December 31, 2022, Mr. Leblanc would not have received any compensation from us in excess of $120,000 during any period of twelve consecutive months in the three year look-back period preceding January 1, 2026, and he would therefore be considered independent under the Nasdaq Listing Rules on January 1, 2026. Other than the compensation previously received as director emeritus, the Board has determined that Mr. Leblanc meets all independence requirements for a member of the audit committee under Rule 10A-3 of the Securities and Exchange Act of 1934, as amended, and the other independence requirements under the Nasdaq Listing Rules.

Current report

The Board also considered Mr. Leblanc’s previous service as a director and chair of the Audit Committee. Based on Mr. Leblanc’s experience and previous service with us, the Board determined that Mr. Leblanc familiarity with our operations, business, supply-chain and manufacturing strategies, and intricacies of our corporate structure is necessary to our current needs. The Board believes that the unforeseen passing of Ms. Russell during a critical period in our operations further necessitates the appointment of a director who is already familiar with our financial operations and our management under the current environment and economic conditions. Accordingly, the Board determined that the appointment of Mr. Leblanc to our Audit Committee as a non-independent director will be in the best interests of the Company and our stockholders in reliance on the exception provided under applicable Nasdaq Listing Rules for membership on the Audit Committee, Compensation Committee and Nominating and Corporate Governance Committee under exceptional and limited circumstances. Based on the foregoing determination, the Board also appointed Mr. Leblanc to serve on the Audit Committee, Compensation Committee and Nominating and Corporate Governance Committee in reliance on the limited exception provided under the Nasdaq Listing Rules. Mr. LeBlanc’s independence under the Nasdaq Listing Rules will be re-evaluated by the Board on or after January 1, 2026.

Current report

On July 29, 2025, we appointed Mr. Jesse Chen to serve as the Chair of the Audit Committee. Mr. Chen currently serves as an independent director, lead director, Chair of the Nominating and Governance Committee, and a member of the Audit Committee and Compensation Committee.

The decrease inresearch and development expenses for the six months ended June 30, 2025 was primarily due tolower product development expenses for crystal ingot processing, partially offset by higher compensation related expenses.

Current report

Interest expense, net decreased $160,000, or 25.4%, to $471,000 for the six months ended June 30, 2025 from $631,000 for the six months ended June 30, 2024.

Previous wording

2020, Investors, which consist of 10 private equity funds, had entered into two sets of definitive transaction documents, each consisting of a capital increase agreement along with certain supplemental agreements in substantially the same form (collectively, the “Capital Investment Agreements”), with Tongmei for a total investment of approximately $48.1 million. The currency used in the investment transactions was the Chinese renminbi, which has been converted to approximate U.S. dollars for this Quarterly Report on Form 10-Q. The remaining investment of approximately $1.5 million of new capital was funded in January 2021. The government approved the approximately $49 million investment in its entirety on January 25, 2021. In exchange for an investment of approximately $49 million, the Investors received a 7.28% redeemable noncontrolling interest in Tongmei.

Current wording

On November 16, 2020, we announced a strategic initiative to access China’s capital markets by beginning a process to list shares of Tongmei in an initial public offering (the “IPO”) on the STAR Market, an exchange intended to support innovative companies in China. We formed and founded Tongmei in 1998 and believe Tongmei has grown into a company that will be an attractive offering on the STAR Market. To qualify for a STAR Market listing, the first major step in the process was to engage private equity firms in China (“Investors”) to invest funds in Tongmei. By December 31, 2020, Investors, which consist of 10 private equity funds, had entered into two sets of definitive transaction documents, each consisting of a capital increase agreement along with certain supplemental agreements in substantially the same form (collectively, the “Capital Investment Agreements”), with Tongmei for a total investment of approximately $48.1 million.

The businesses of our PRC subsidiaries and PRC joint ventures are subject to complex and rapidly evolving laws and regulations in the PRC, which can change quickly with little advance notice. The PRC government is a single party form of government with virtually unlimited authority and power to intervene in or influence commercial operations in China. In the past, we have experienced such intervention or influence by the PRC government and a change in the rules and regulations in China when we were instructed by the Beijing municipal government to relocate part of our manufacturing facility in Beijing and expect that such intervention or influence or change in the rules and regulations in China could occur in the future.

Previous wording

In late 2024 and early 2025, a new round of trade restrictions was announced by China and the United States. On December 3, 2024, China issued further rules restricting exports of materials that can typically be used in military applications including antimony, gallium, germanium and other superhard materials. The effective date was December 3, 2024, the same day as the announcement itself. Reciprocally, the United States increased tariffs on many items from China from 25% to 50%, effective January 1, 2025. On February 1, 2025, the United States again further increased the tariff on imports of many products from China, including our wafer substrates, to 60%. On March 4, 2025, the United States further increased the tariff on imports of many products, including our wafer substrates, to 70%. In the first half of April 2025 we observed high volatility in tariffs put in place by the United States. At least four separate tariffs were imposed by the United States on products from China. Tariffs on our products increased to 100%. We have little or no germanium imports into the U.S. and historically a relatively small value of imports of gallium arsenide wafers into the U.S. In 2024 only 8% of our total worldwide revenue was from sales in North America. Our primary revenue generator derived from imports into the U.S. is indium phosphide substrates. While Tongmei has generally received the required permits for exports to countries in Asia and Europe, our U.S. gallium arsenide customers are considered “dual use” customers: in addition to commercial applications they have significant levels of military involvement. As such, no permits for gallium arsenide to the U.S. have yet been approved. On February 4, 2025, China added indium phosphide substrates to its export control list. As a result, the three wafer substrate product lines manufactured by Tongmei all require permits from China’s Ministry of Commerce before they can be exported from China. To our knowledge, indium phosphide is rarely used in military applications and we can reasonably expect that export permits to ship our indium phosphide substrates to the U.S. will be granted. The portal to apply for exports of indium phosphide from China opened in March and we immediately began to submit our applications. However, since the requirement for such export permits is new, the timing for when permits will be granted remains uncertain and we are unable to estimate when we will receive the necessary export permits to resume shipping our indium phosphide substrates to the U.S. We are actively monitoring and following-up on the status of our applications.

We have created a vertically integrated supply chain and transfer cash through our corporate structure in three ways. First, we capitalize our investments in our PRC subsidiaries.

Our independent registered public accounting firm is BPM LLP (“BPM”), which is registered with the PCAOB. The Holding Foreign Companies Accountable Act (the “HFCA Act”) requires that the PCAOB determine whether it is unable to inspect or investigate completely registered public accounting firms located in a non-U.S. jurisdiction because of a position taken by one or more authorities in that jurisdiction. On December 16, 2021, the PCAOB issued a report on its determinations that the PCAOB is unable to inspect or investigate completely registered public accounting firms headquartered in the PRC and Hong Kong because of positions taken by PRC authorities in those jurisdictions. BPM is headquartered in the United States and not in the PRC or Hong Kong. As such, BPM is subject to the determinations announced by the PCAOB. Accordingly, the Company does not expect the HFCA Act, the Accelerating Holding Foreign Companies Accountable Act and the related regulations to affect the Company and does not expect to be identified by the Securities and Exchange Commission, or SEC, under the HFCA Act. On December 15, 2022, the PCAOB vacated its 2021 determinations that the positions taken by authorities in the PRC and Hong Kong prevented it from inspecting and investigating completely registered public accounting firms headquartered in those jurisdictions. See “Although the audit report is prepared by an independent registered public accounting firm that is currently inspected fully by the PCAOB, there is no guarantee that future audit reports will be prepared by an independent registered public accounting firm that is completely inspected by the PCAOB” under the section entitled “Risk Factors” in Part II, Item 1A below for further information on risks related to our foreign operations and dependence.

In the first months of the year 2025, the Company has been impacted by escalating trade tensions and regulations. On December 3, 2024, China issued further rules restricting exports of materials that can typically be used in military applications including antimony, gallium, germanium and other superhard materials. Reciprocally, the United States increased tariffs on many items from China from 25% to 50%, effective January 1, 2025. On February 1, 2025, the United States again increased the tariff on imports of many products from China, including our wafer substrates, to 60%. On February 4, 2025, China added indium phosphide substrates to its export control list. On March 4, 2025, the United States further increased the tariff on imports of many products, including our wafer substrates, to 70%. On April 2, 2025, the United States again announced a baseline 10% tariff on product imports from almost all countries and individualized higher tariffs on certain other countries, including up to 145% tariffs on certain products from China. Several tariff announcements have been followed by announcements of limited exemptions and temporary pauses, however, our wafer substrates continue to be subject to tariffs of approximately 100%.

Due to the uncertainties pertaining to export restrictions in China and tariffs and tariff levels in the United States, it is difficult for us to reliably forecast the short-term or ongoing impact to our business or that of our customers but is expected that tariffs and export regulations would negatively impact our revenues, profitability and cash flows. We are closely monitoring the fluid nature of proposed tariffs and any impact they may have on our operations and will continue to monitor macroeconomic conditions and evaluate the financial and operational impact of ongoing trade policy shifts.

Previously, as of August 1, 2023, Tongmei was required to secure permits from the applicable Chinese authorities to export gallium arsenide and germanium substrates. Materials that could be used in military applications, specifically including weapons of mass destruction, are the primary focus. We have little or no germanium imports into the U.S. and historically a relatively small value of imports of gallium arsenide wafers into the U.S. Our primary revenue generator derived from imports into the U.S. is indium phosphide substrates. In 2024, approximately 8% of our revenue was generated by sales to customers in the U.S. To our knowledge, indium phosphide is rarely used in military applications and we can reasonably expect that export permits to ship our indium phosphide substrates to the U.S. will be granted. The portal to apply for exports of indium phosphide from China opened in March and we immediately began to submit our applications. However, since the requirement for such export permits is new, the timing for when permits will be granted remains uncertain and we are unable to estimate when we will receive the necessary export permits to resume shipping our indium phosphide substrates to the U.S. We are actively monitoring and following-up on the status of our applications.

In 2024, approximately 8% of our revenue was generated by sales to customers in the U.S. On February 4, 2025, China added indium phosphide substrates to its export control list. As a result, the three wafer substrate product families manufactured by Tongmei all require permits from China’s Ministry of Commerce before they can be exported from China. The portal to apply for exports of indium phosphide from China opened in March and we immediately began to submit our applications. On June 11, Tongmei was informed that it has satisfied the applicable requirements for a permit to export indium phosphide and has received its initial export permits from the Ministry of Commerce of the People’s Republic of China to resume shipping indium phosphide substrates to certain customers in Europe and Japan. More recently, we have also obtained export permits for indium phosphide shipments to the UK and Canada. To our knowledge, indium phosphide is rarely used in military applications and we can reasonably expect that export permits to ship our indium phosphide substrates to the U.S. will be granted.

On February 4, 2025, China added indium phosphide substrates to its export control list. As a result, the three wafer substrate product families manufactured by Tongmei all require permits from China’s Ministry of Commerce before they can be exported from China. The portal to apply for exports of indium phosphide from China opened in March and we immediately began to submit our applications. On June 11, Tongmei was informed that it has satisfied the applicable requirements for a permit to export indium phosphide and has received its initial export permits from the Ministry of Commerce of the People’s Republic of China to resume shipping indium phosphide substrates to certain customers in Europe and Japan. More recently, we have also obtained export permits for indium phosphide shipments to the UK and Canada. To our knowledge, indium phosphide is rarely used in military applications and we can reasonably expect that export permits to ship our indium phosphide substrates to the U.S. will be granted. However, since the requirement for such export permits is new, the timing for when permits will be granted remains uncertain and we are unable to estimate when we will receive the necessary export permits to resume shipping our indium phosphide substrates to the U.S. We are actively monitoring and following up on the status of our applications.

Revenue decreased $13.3 million, or 26.2%, to $37.3 million for the six months ended June 30, 2025 from $50.6 million for the six months ended June 30, 2024. The substrate revenue decrease for the six months ended June 30, 2025 as compared to the same period in 2024 was primarily the result oflower demand for InP wafer substrates used for data center applications and in passive optical networks, as a result of export restrictions imposed by the China government, and decreased demand for GaAs wafer substrates due to decreased demand across a number of applications and weaker demand for Ge wafer substrates in China. Raw materials sales increased $1.0 million, or 7.0%, to $15.0 million for the six months ended June 30, 2025 as compared to the same period in 2024. The increase inraw materials revenue for the six months ended June 30, 2025 as compared to the same period in 2024 was primarily the result of an increase in sales of refined gallium and from the sale of recycled materials, partially offset by lower demand for pBN crucibles resulting from weaker market demand.

Revenue in China decreased $2.5 million for the three months ended June 30, 2025, primarily due to lower demand for our InP and Ge wafer substrates and refined gallium sold by one of our consolidated subsidiaries, partially offset by higher demand for our GaAs wafer substrates. Revenue in Taiwan decreased $2.9 million, primarily due to the impact of China export restrictions on our InP and GaAs wafer substrates. Revenue in Japan decreased $0.1 million, primarily due to the impact of China export restrictions on our GaAs and InP wafer substrates, partially offset by higher demand for pBN crucibles sold by one of our consolidated subsidiaries. Revenue in Asia Pacific decreased $0.3 million, primarily due to the impact of China export restrictions on our InP and GaAs wafer substrates and decreased demand for pBN crucibles sold by one of our consolidated subsidiaries. Revenue in Europe decreased $3.1 million, primarily due to the impact of China export restrictions on our GaAs, InP and Ge wafer substrates and lower demand for pBN crucibles sold by one of our consolidated subsidiaries. Revenue in North America decreased $1.1 million, primarily due to the impact of China export restrictions on our InP and GaAs wafer substrates and lower demand for pBN crucibles sold by one of our consolidated subsidiaries.

Gross profit decreased 13.6 million, or 98.6%, to a profit of $0.2 millionfor the six months ended June 30, 2025 from $13.7 million for the six months ended June 30, 2024. The decrease in gross profit is primarily the result of significant unfavorable yields charged to cost of goods sold in our gallium arsenide production lines. These charges resulted in a negative gross margin as a percent of revenue. Further, the export restrictions imposed by China on indium phosphide had a negative impact on product mix and on total substrate revenue. Sales of indium phosphide wafers were reduced significantly. Lower substrate revenue resulted in an increase in unabsorbed overhead charged to cost of goods sold.

On November 16, 2020, we announced a strategic initiative to access China’s capital markets by beginning a process to list shares of Tongmei in an initial public offering (the “IPO”) on the STAR Market, an exchange intended to support innovative companies in China. We formed and founded Tongmei in 1998 and believe Tongmei has grown into a company that will be an attractive offering on the STAR Market. To qualify for a STAR Market listing, the first major step in the process was to engage private equity firms in China (“Investors”) to invest funds in Tongmei. By December 31,
