A Breach of Confidence Wipes Out Half a Billion in Market Value at POET Technologies

A CFO's offhand remark triggered a 57% stock crash, Marvell order cancellations, and multiple class-action lawsuits over alleged investor misrepresentation.

A single offhand remark by a senior executive has triggered a chain reaction that has erased roughly 57 percent of POET Technologies’ share price since mid-April, turning what was a high-flying AI chip stock into a target for class-action lawsuits. The company’s market capitalization now stands at approximately $921 million, down sharply from its April peak.

The crisis erupted after Chief Financial Officer Thomas Mika made public comments about the company’s business relationships, allegedly violating a non-disclosure agreement. The fallout was swift and brutal. Marvell Technology, which had acquired POET’s customer Celestial AI in February, cancelled all outstanding orders on April 23. The loss of that business leaves a gaping hole in POET’s order book that a recently announced $5 million production contract with another technology firm does little to fill.

Legal Troubles Mount

The contractual rupture has opened the floodgates to litigation. At least four U.S. law firms — including Block & Leviton, Faruqi & Faruqi, and Rosen Law Firm — are preparing class-action suits against the company. They allege that POET systematically misled investors during the trading period from April 1 through April 27.

A central accusation concerns the company’s classification under U.S. tax law. Plaintiffs claim POET concealed its status as a passive foreign investment company (PFIC), a designation that can carry significant tax penalties for American shareholders. The company attempted to address the issue in mid-April by pledging to provide documentation for a tax-neutral classification for 2025, and management plans to put a relocation of the corporate headquarters to the United States to a shareholder vote at the annual meeting in late June.

Mika himself faces direct scrutiny. The lawsuits allege he misrepresented the stability of the company’s order pipeline in public communications, raising questions about the adequacy of POET’s internal controls.

A Tale of Two Balance Sheets

Financially, POET Technologies presents a stark contradiction. The company sits on a cash pile of roughly $430 million, accumulated through successful fundraising rounds, which provides ample liquidity. But its operating business generates negligible revenue. In the fourth quarter of last year, the company reported sales of just $341,200 against a net loss of approximately $43 million, or 32 cents per share.

The disconnect between the company’s market valuation and its revenue stream has long been a point of contention. The price-to-sales ratio remains far above industry averages, and analysts have responded to the recent turmoil by downgrading their recommendations. The consensus now leans toward “sell” or “speculative.”

A Tightening Timeline

For investors seeking recourse, the clock is ticking. Shareholders have until June 29, 2026, to register as lead plaintiffs in the class-action suits. Three days earlier, on June 26, management must face shareholders at the annual meeting, where questions about the Marvell debacle, the PFIC issue, and the company’s strategic direction are certain to dominate the agenda.

The company has signaled it intends to deliver more than 30,000 optical engine units this year, but the loss of its most prominent customer partnership casts doubt on whether that target remains achievable. For now, POET Technologies finds itself fighting on two fronts: defending its legal position while trying to convince the market that its underlying technology story remains intact.
