POET Technologies Provides Clarity on its Passive Foreign Investment Company (PFIC) Status

Commits to Taking Actions to Address Potential Tax Consequences to U.S. Shareholders

Announces Board Approval to Redomicile in the U.S.

TORONTO, April 14, 2026 (GLOBE NEWSWIRE) — POET Technologies Inc. (“POET” or the “Company”) (Nasdaq: POET) today announced that it will make available the information necessary for its U.S. shareholders to make a “QEF” election. If a U.S. shareholder timely makes such an election, it should mitigate certain potential adverse U.S. federal income tax consequences to it that could otherwise result from the Company’s status as a passive foreign investment company (or “PFIC”) for the year ended December 31, 2025. Further, a U.S. shareholder that makes a QEF election with respect to POET for fiscal year 2025 is not expected to have current income inclusions for fiscal year 2025 as a result of the QEF election, and consequently, a QEF election with respect to such year is expected to result in no negative U.S. federal income tax consequences for U.S. shareholders that have continued to hold their POET shares.

According to Thomas Mika, the Company’s Executive Vice President & Chief Financial Officer, “As the Company looks to 2026, we believe that we will not qualify as a PFIC. Nevertheless, the Board of Directors has declared its intention to move the Company’s headquarters to and redomicile the Company in the U.S. so that it will no longer be a foreign corporation, which would eliminate the possibility of the Company being classified as a PFIC in future years. To the extent that any redomiciling of the Company requires shareholder approval, which will depend upon the manner in which that is undertaken, we plan to place the matter on the agenda for shareholder approval at the upcoming Annual General and Special Meeting, currently scheduled for Friday, June 26, 2026.”

Background on PFIC Status and the QEF Election

As a company organized in Canada, POET may be classified as a PFIC. Based on our income and assets for the year ended December 31, 2025, we currently believe that we will be treated as a PFIC for the year ended December 31, 2025. As we have previously disclosed, if the Company has been a PFIC, U.S. persons who hold its shares may be subject to certain adverse U.S. federal income tax consequences. A U.S. shareholder may mitigate such consequences by making a timely “qualified electing fund” or “QEF” election with respect to its POET shares by the due date of such U.S. shareholder’s U.S. federal income tax return for the first tax year in which they held such POET shares and to which the election will apply, giving effect to the extensions that are available (e.g., the automatic extension to October 15, 2026 for 2025 that an individual taxpayer can obtain by submitting a form by April 15, 2026).

A QEF election, once effective, generally requires a U.S. shareholder to include in gross income on a current basis its pro rata share of the PFIC’s ordinary earnings and net capital gain, regardless of whether such amounts are actually distributed (subject to a separate election to defer payment of taxes, which deferral is subject to an interest charge). In order to make and maintain a valid QEF election, shareholders must have access to certain information from the Company, including an annual PFIC Annual Information Statement setting forth the shareholder’s pro rata share of the Company’s ordinary earnings and net capital gain for the taxable year.

Commitment to Providing QEF Information

POET recognizes that many of its shareholders are U.S. persons who may benefit from making a QEF election. Accordingly, the Company commits to preparing and making available a PFIC Annual Information Statement for each taxable year in which the Company is determined to be, or reasonably believes it may be, a PFIC. The PFIC Annual Information Statement will be made available on the Company’s website and upon request to the Company’s investor relations.

The Company encourages U.S. shareholders that are considering making a QEF election to consult with their own tax advisors regarding their individual circumstances, potential alternatives (such as making a “mark-to-market” election, if available) and the procedures for making a QEF election.

Practical Impact for Fiscal Year 2025

U.S. shareholders should be aware that, if they timely make a QEF election with respect to POET shares, they should not expect to have any current U.S. federal income inclusions as a result of the election in respect of holding such shares during 2025. The Company reported a net loss for the fiscal year ended December 31, 2025 and, accordingly, does not expect to have any ”earnings and profits” for that year. Because a QEF election requires the shareholder to include in income only its pro rata share of the Company’s ordinary earnings and net capital gain—and not its losses—a QEF election with respect to POET for fiscal year 2025 is expected to result in a zero income inclusion for U.S. shareholders. In other words, while the election may be useful as an important protective measure for future years, it is not expected to carry an incremental tax burden for fiscal year 2025 given the Company’s net loss position.

Further Action

The Company believes that it will not be a PFIC for its fiscal year ending December 31, 2026, based on the Company’s current expectations. However, whether that will ultimately be the case will depend upon the nature of the Company’s income and assets for the year and cannot be determined with any certainty at this point in the year. In any event, the Company is committed to evaluating further actions to mitigate the potential impact of its PFIC status for U.S. shareholders for future tax years. Specifically, the Company’s board of directors has approved the Company redomiciling in the U.S., which, if it is subject to shareholder approval, will be submitted to POET shareholders for approval in connection with the Company’s next annual general meeting. In considering the structuring of the redomiciling of the Company and any additional actions, the Company intends to take into account the potential tax impact to the Company’s U.S. and non-U.S. shareholders, among other factors. There can be no assurance that the Company will complete the redomiciling of the Company or pursue any additional or alternative actions.
