POET Technologies Faces a June Gauntlet: Market Setback, Client Loss, and a Tax Reclassification Vote
10.06.2026 - 16:25:13 | boerse-global.de
The photonics upstart POET Technologies has seen its stock slashed by more than half since May, as a pair of unrelated crises converge on two pivotal dates later this month. On June 26, shareholders will vote on a plan to move the company’s legal domicile from Canada to the United States, a move aimed at sidestepping a punishing tax designation. Three days later, the window closes for investors to join a class-action lawsuit that accuses POET of misleading the market about that very same tax risk.
Industry headwinds compound the pain
The near-term pressure is not solely of POET’s own making. On June 9, research firm SemiAnalysis released a note forecasting that commercial adoption of co-packaged optics (CPO) — a key enabling technology for POET’s products — will likely slip to 2028 or 2029, later than earlier expectations. The report triggered a broad sell-off in optical modules and AI photonics stocks. POET’s shares lost roughly 13 percent in US trading that day alone. Industry-wide challenges with system yields remain a persistent bottleneck for CPO, and POET is not immune to those technical hurdles.
The Celestial AI blow-up
But the more damaging blow came weeks earlier, when POET disclosed that Celestial AI — a customer whose orders were being routed through Marvell Semiconductor — had cancelled all outstanding purchase orders. The reason: an alleged breach of a non-disclosure agreement. According to the company, a party involved in the discussions violated confidentiality by speaking about business arrangements in a public interview. The cancellation wiped 47.3 percent from POET’s stock in a single session.
Several class-action complaints were subsequently filed in the US District Court for New Jersey. They claim that between April 1 and April 27, POET misrepresented the risk that it would be classified as a Passive Foreign Investment Company (PFIC) — a US tax category that can impose severe penalties on shareholders. The law firm Gross Law Firm has reminded affected investors that they must file as lead plaintiffs by June 29 to participate.
Should investors sell immediately? Or is it worth buying POET Technologies?
Redomestication as a remedy
POET has acknowledged that it will be treated as a PFIC for the 2025 tax year. Management’s response is to reincorporate in the United States, a step that would eliminate the PFIC problem for future years. Shareholders will vote on the redomestication proposal at the annual general meeting on June 26. If approved, the company also intends to allow US investors to make a “Qualified Electing Fund” election for 2025. Because POET posted a net loss last year, that election would not trigger immediate tax liabilities.
Yet the pending lawsuits concern past statements, not the future corporate structure. A change of address does not retroactively erase disclosure allegations.
Financial tightrope
POET’s underlying business remains in the red. First-quarter 2026 revenue came in at roughly $503,000 — triple the year-ago figure but still a fraction of the company’s operating costs. The net loss for the quarter was $12.3 million. A massive capital raise earlier this year injected fresh cash but diluted existing shareholders: 19.05 million new shares and warrants were issued.
Management is pinning its hopes on a $50 million contract with Lumilens for electro-optical interposer engines. If development and production milestones are met, the total value could exceed $500 million over five years. The company plans to roughly decuple its manufacturing capacity, aiming to ship more than 30,000 optical engines in 2026, with mass production starting in 2027. Technical samples are expected later this year.
POET Technologies at a turning point? This analysis reveals what investors need to know now.
Technical fragility
The stock currently trades at €8.97, some 52 percent below its May high of €18.84. It is hovering just above its 50-day moving average of €9.17 — a level that often acts as a technical support or resistance zone. The annualized 30-day volatility stands at over 200 percent, underscoring the extreme uncertainty surrounding the name.
The June 26 shareholder vote and the June 29 class-action deadline will determine whether POET can shed its most pressing legal and structural liabilities. Winning back investor confidence, however, is likely to take far longer.
