POET Technologies' Week of Reckoning: A Shareholder Vote and a Class-Action Deadline Converge

POET shareholders vote on June 26 to redomicile from Canada to US to resolve PFIC tax issues; lead plaintiff deadline for securities class-action follows on June 29 after NDA breach triggered stock collapse.

For POET Technologies, the closing week of June 2026 shapes up as a defining moment. On the 26th, shareholders will decide whether to move the company's legal home from Canada to the United States — a step designed to wipe out the unfavourable PFIC tax designation that has already drawn a legal challenge. Three days later, the deadline for lead plaintiff applications in a securities class-action lawsuit arrives. The two events, separated by a single weekend, will test whether the photonics pioneer can contain a reputational crisis that erupted in late April.

The crisis began with a single interview. On April 21, chief financial officer Thomas Mika spoke publicly about the company's relationships with Marvell Semiconductor and Celestial AI — a conversation that, according to the lawsuits, violated a non-disclosure agreement with Marvell. CEO Suresh Venkatesan is also named as having known about the confidential information. Within 48 hours, Marvell cancelled all outstanding orders, including the initial production units that POET had announced back in April 2023, citing the NDA breach. On April 27, the stock collapsed by more than 45% intraday, with some reports citing a 47% decline. Celestial AI, the start-up at the centre of the dispute, had by then been absorbed into Marvell Technology.

Four law firms have now lined up against the company. Bernstein Liebhard, Rosen Law Firm, Faruqi & Faruqi, and Levi & Korsinsky have all filed complaints in the US District Court for the District of New Jersey, covering purchases made between April 1 and April 27. The allegations fall into two buckets: that POET failed to disclose its potential status as a Passive Foreign Investment Company, a designation that carries hefty tax disadvantages for US holders, and that it misled investors about the stability of its commercial ties after Mika's comments endangered the Marvell relationship. Investors who do not seek lead plaintiff status can still participate in any eventual settlement.

Institutional activity in the first quarter paints a picture of mixed conviction. Citadel Advisors bulked up its stake by 273%, ending the period with nearly 1.85 million shares. Tudor Investment Corp and Millennium Management both opened new positions. Overall, 68 institutional investors increased their holdings while 58 trimmed theirs — a split that hints at the uncertainty surrounding the stock even before the NDA dispute became public.

Operationally, the first quarter numbers show a company still burning cash at an uncomfortable rate. Revenue came in at roughly $503,000, more than triple the year-ago figure, but the net loss widened to $12.3 million, pushing the accumulated deficit to $291 million. Management acknowledged a material weakness in internal controls. Those figures make the $400 million registered direct placement completed in mid-May all the more critical. Priced at $21.00 per unit — a premium to the prevailing market rate — the offering was finished before the stock fully absorbed the April shock. Proceeds are earmarked for scaling up the optical interposer manufacturing, expanding into fast AI interconnects and light-source products, and potential acquisitions.

A separate bright spot came in May with a supply and development agreement from Lumilens for photonic wafer integration in AI networks. The initial order is worth $50 million, with the option to expand to more than $500 million over five years if development and manufacturing milestones are hit. The deal lends some weight to the growth narrative, though it remains contingent on execution. Management changes signal a shift in focus: Dr. Sandeep Kumar was appointed chief operating officer on May 12 to steer the company from research toward volume production, while Mika has said he will retire once a successor for the CFO role is named.

The two critical dates now loom with different implications. A vote to redomicile to the US would resolve the PFIC issue, neutering one of the lawsuit's main allegations — but the lead plaintiff deadline on June 29 ensures that the broader fraud claims will continue to be litigated. POET enters this week with fresh capital and a promising contract, but the memory of a 45% one-day crash and an NDA breach that cost it a major customer will not be erased by a simple change of address.
