What is the POET Technologies Investigation About?

Previously, shares of POET Technologies Inc. (“POET Technologies”) plummeted over 47% on April 27, 2026, after the company disclosed that Celestial AI, which was recently acquired by Marvell, had cancelled all purchase orders, citing alleged confidentiality violations.

On April 21, 2026, POET Technologies CFO Thomas Mika told Stocktwits that the company had secured an order from Celestial AI and planned to “continue that relationship [with Marvell] and build it over time.” Just a week later, on April 27, 2026, POET Technologies announced that all purchase orders it had received from Celestial AI were now cancelled, including initial production units first disclosed by the company in an April 25, 2023 press release. Marvell gave POET written notice on April 23, 2026 that it was cancelling the orders because “the company had wrongly shared details about the purchase orders and shipping information, breaking confidentiality rules,” as reported by Yahoo Finance.

Then, on April 28, 2026, a lawsuit was filed on behalf of POET Technologies investors, alleging that CFO Thomas Mika’s statements on April 21, 2026 were “materially false and misleading,” and that he failed to disclose that his statements were a breach of the confidentiality agreement and could result in the termination of POET Technologies’ deal with Marvell and subsequently harm the business.

Additionally, the lawsuit claims that statements in POET Technologies’ 2025 Annual Report misled investors by understating the likelihood of the company being deemed a passive foreign investment company (PFIC) by the IRS, a designation that could negatively impact the company’s valuation and reduce demand for POET stock.
