POET Technologies Faces Twin Deadlines as Legal Storm and Strategic Pivot Converge

POET Technologies shareholders vote on US headquarters move to shed PFIC status while class-action lawsuit deadline looms; stock falls 21% amid Celestial AI order cancellation and weak Q1 results.

Two dates stand out on POET Technologies' calendar this June, and neither is about product launches. On the 26th, shareholders vote on moving the corporate headquarters to the United States. Three days later, the window closes for investors to step forward as lead plaintiffs in a budding class-action lawsuit. The convergence has sent the stock into a tailspin — shares tumbled more than 21 percent on Friday alone.

The relocation vote is more than a logistical formality. POET Technologies was classified as a Passive Foreign Investment Company, or PFIC, for the 2025 tax year — a label that spooks institutional US investors because of punitive tax treatment on American shareholders. A successful ballot would remove that hurdle at a stroke.

But the legal front looks messier. Three law firms — DJS Law Group, Pomerantz, and Rosen Law Firm — have posted independent reminders about the class-action suit, which covers trading between April 1 and April 27, 2026. Two other firms, Faruqi & Faruqi and Levi & Korsinsky, have also filed complaints. The core allegations: POET misrepresented its PFIC status, and a senior manager disclosed confidential business information in a public interview, violating securities laws.

The lawsuit traces back to a shock in late April. Marvell Semiconductor acquired Celestial AI and immediately cancelled all purchase orders from that customer, including first-production units POET had trumpeted publicly in 2023. Marvell fired off a letter on April 23, 2026, arguing that the disclosure of order details breached confidentiality agreements. The stock cratered more than 45 percent in a single session four days later.

That single client defection punctured the company's investment narrative, which rests on commercialising optical engines and high-speed interconnects for data centres. Without Celestial AI, a key pillar of that story collapsed.

The financials underscore how early-stage the operation remains. First-quarter 2026 revenue came in at roughly $503,000 from engineering services and product sales. The net loss widened to $12.34 million, pushing the accumulated deficit to $291 million. POET also reported a material weakness in its internal controls.

Management didn't sit idle. In mid-May, POET closed a $400 million capital raise, issuing nearly 19 million new shares plus matching warrants to an institutional investor at $21.00 each. Proceeds are earmarked for manufacturing infrastructure, acquisitions, and R&D. The goal is to decuple production capacity and ship more than 30,000 optical engines this calendar year.

On the commercial side, a $50 million supply and development agreement with Lumilens offers a brighter spot. The contract includes an option for over $500 million across five years, covering 800G and 1.6T interconnects as well as co-packaged optics. Engineering samples are expected by the end of 2026.

The stock closed Friday at €10.48, a 21.3 percent drop for the day. That leaves it roughly 44 percent below its 52-week high of €18.84, reached in mid-May on the Lumilens euphoria. Despite the recent rout, shares are still up more than 70 percent year-to-date — and nearly 194 percent on a 12-month basis. Annualised volatility stands above 260 percent, reflecting how violently the stock swings on news.

New COO Dr. Sandeep Kumar, a seasoned semiconductor executive, has been brought in to shepherd the transition from development to volume production. The twin deadlines on June 26 and June 29 will test whether the company can steady itself — or whether the next jolt is already around the corner.
