A Single Interview Cost POET Technologies Nearly Half Its Market Value

POET Technologies shares crashed 45% after Marvell cut ties over a confidentiality breach. Now, four class-action lawsuits allege PFIC tax misrepresentation, as the company plans a US redomicile.

The math is brutal. On April 27, POET Technologies shares plunged more than 45% in a single trading session, wiping out billions in market capitalization. The trigger? A manager’s public remarks about confidential business arrangements that prompted Marvell Semiconductor to sever all ties.

Marvell, which had acquired Celestial AI, terminated every outstanding order with POET on April 23, citing a breach of confidentiality. The semiconductor giant alleged that a POET executive disclosed sensitive details about their commercial relationship during an interview. Four days later, the stock cratered.

Lawsuits Arrive Before the Dust Settles

The selloff drew immediate attention from the plaintiffs’ bar. Within weeks, four separate class-action lawsuits were filed against the photonics company. All target the same issue: whether POET misrepresented its tax status to investors.

The complaints center on the company’s classification as a Passive Foreign Investment Company, or PFIC, under US tax law. For American shareholders, PFIC designation carries punitive tax treatment. The lawsuits allege that POET’s management knew or should have known about this exposure but failed to disclose it properly.

The class period covers purchases made between April 1 and April 27, 2026. Investors have until June 29 to file motions to serve as lead plaintiff.

A Stealth Attack From Short Sellers

The legal storm didn’t emerge from a vacuum. On April 14, Wolfpack Research published a scathing report labeling POET a “questionable stock promotion scheme.” The short-selling research firm zeroed in on the same PFIC issue that now underpins the class actions.

Wolfpack’s intervention added fuel to a fire that was already smoldering. By the time Marvell pulled the plug, the stock was already under pressure from skeptical investors.

The Redomicile Gambit

POET’s board is fighting back with a structural solution. The company plans to move its corporate domicile from Canada to the United States. Management believes this will eliminate the PFIC classification going forward.

Shareholders will vote on the relocation at the annual meeting scheduled for June 26, 2026. If approved, the move would resolve the tax headache for future periods — though it does nothing to address the lawsuits tied to past disclosures.

Cash Is King — But Revenue Is Scarce

Despite the turmoil, POET is not a company in financial distress. The balance sheet shows approximately $430 million in cash, raised largely through recent capital raises totaling around $375 million. That war chest provides ample runway to fund operations and legal defense.

The operating story, however, remains embryonic. In the fourth quarter of 2025, POET generated just $341,000 in revenue and reported a loss of $0.32 per share. For the full year, revenue reached roughly $1 million against a net loss of $63 million.

Management insists the business is gaining traction. POET recently secured a $5 million production order for optical engines from an unnamed technology partner. The company still targets delivery of more than 30,000 optical engines in 2026, with partnerships at LITEON Technology and Lessengers providing a channel into the AI data center market.

Two Dates That Define the Near Term

The stock has stabilized somewhat, trading between $6.69 and $7.48 on May 4 with volume of about 26 million shares — well below the 72 million average. The market capitalization sits at roughly $1.12 billion.

But the calendar is unforgiving. June 26 brings the shareholder vote on the US relocation. Three days later, on June 29, the lead plaintiff deadline expires in the class action. Between those two milestones, the market will learn whether POET can rebuild trust with both its investors and its customer base after a single interview undid months of progress.
