ATLANTA, GA – – (Globe Newswire – April 29, 2026) – – A shareholder class action lawsuit has been filed against POET Technologies Inc. (“POET”) (NASDAQ: POET). The lawsuit alleges that Defendants made false and misleading statements and/or failed to disclose material adverse facts regarding POET’s business, operations, and prospects, including allegations that: (1) POET misrepresented its tax status due to it likely being deemed a passive foreign investment company (or “PFIC”) under U.S. tax laws which, if not properly reported by each U.S. stockholder, would have negative tax implications for those U.S. stockholders; (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, despite affirming that he was not violating a non-disclosure agreement, in fact violated a business agreement by speaking about POET’s business agreements in a public interview, thus endangering POET’s business prospects.
