The complaint alleges that POET Technologies failed to disclose its status as a passive foreign investment company under U.S. tax laws. Plaintiffs argue that this oversight, if left unaddressed, poses significant tax liabilities for U.S. stockholders and undermines the company’s overall valuation. Beyond the tax implications, the lawsuit highlights a breach of professional conduct; a defendant allegedly violated a non-disclosure agreement by discussing sensitive business arrangements during a public interview, potentially jeopardizing the firm's commercial standing.

The Gross Law Firm, which initiated the notice, asserts that these omissions rendered the company's public statements regarding its operations and prospects materially false. Shareholders who registered their interest will be enrolled in portfolio monitoring software to receive updates throughout the litigation lifecycle. Participation in the action carries no upfront costs for investors, though the window to petition for lead plaintiff appointment closes on June 29, 2026.
