If you suffered a loss on your POET investments, you have until June 29, 2026 to request lead plaintiff appointment. Courts do not consider lead plaintiff applications submitted after this deadline.

What Is This Lawsuit About? The lawsuit alleges that (1) POET Technologies misrepresented its tax status due to it likely being deemed as a passive foreign investment company (“PFIC”) under U.S. tax laws which, if not properly reported by each U.S. stockholder, would have negative tax implications; (2) the foregoing tax issue would, if discovered, make POET a less attractive investment than it would otherwise be, thus threatening POET’s valuation; and (3) Defendant Thomas Mika (the Company’s Executive Vice President and CFO), despite affirming that he was not violating a non-disclosure agreement, in fact violated a business agreement by speaking about POET business agreements in a public interview, thus endangering POET business prospects.

On April 14, 2026, Wolfpack Research issued a report entitled “We Believe POET is An Obvious Stock Promote, Has Created An IRS Nightmare: US Holders Have Until April 15^th To Act.” The release states that “POET set US investors on a collision course with the IRS by accumulating so much cash through dilution, and generating so little operating revenue that our analysis, corroborated by multiple experts, show they qualify as a Passive Foreign Investment Company—or a PFIC” which would make the stack an unattractive investment to investors. On this news, the price of POET shares declined by $0.59 per share, or approximately 8%, from $7.30 per share on April 13, 2026 to close at $6.71 on April 14, 2026.

On April 27, 2026, the Company issued a press release entitled “POET Technologies Provides Purchase Order Update.” The release disclosed “the cancellation of all purchase orders received by the Company from Celestial AI, including the ones for initial production units first disclosed by the Company in a press release on April 25, 2023. Marvell Semiconductor Inc., which acquired Celestial AI, provided written notice of the cancellation to the Company on April 23, 2026. As the basis for the cancellation, Marvell indicated that the Company had made disclosures of information related to the Purchase Order and shipping information in contravention of its confidentiality obligations.” On this news, the price of POET shares declined by $7.15 per share, or approximately 47.4%, from $15.10 per share on April 24, 2026 to close at $7.95 on April 27, 2026.

The Lead Plaintiff Appointment Process. The federal securities laws permit any investor who acquired eligible securities during the class period to seek appointment as lead plaintiff in a class action lawsuit. Courts typically appoint the investor(s) with the largest financial loss in the case and the ability to represent the class rather than investors with simply the largest investment portfolio. Courts regularly appoint individual investors, whether acting alone or as a group, as lead plaintiffs. The rights of any investor who bought shares during the class period are generally already protected. However, lead plaintiffs have the power to influence case strategy and have a say in settlement decisions, as well as decisions concerning allocation of settlement funds among class members.
