NEW YORK, May 13, 2026 — March 31, 2026. April 14, 2026. April 21, 2026. April 27, 2026. Between these four dates, POET Technologies Inc. (NASDAQ: POET) shareholders watched the stock rapidly climb before abruptly falling >47%. A securities class action has been filed on behalf of purchasers between April 1, 2026 and April 26, 2026. Find out if you are eligible to recover losses. You may also contact Joseph E. Levi, Esq. at jlevi@levikorsinsky.com or (212) 363-7500.
Shares collapsed 47.3% on the final day of the Class Period after the Company disclosed that Marvell Semiconductor Inc. cancelled all Celestial AI purchase orders. The lead plaintiff deadline is June 29, 2026.
March 31, 2026: The Annual Report and the PFIC Admission
After the market closed, POET filed its 2025 Annual Report on Form 20-F with the SEC. Buried in the risk factors was a critical admission: the Company believed it “may be treated as a PFIC” for the preceding taxable year. The filing carried SOX certifications signed by the CEO and the CFO attesting to accuracy. The lawsuit contends this disclosure materially understated the severity of PFIC classification for U.S. holders.
April 14, 2026: The Wolfpack Report and First Stock Decline
Wolfpack Research published a report calling POET “an obvious stock promote” and detailing how PFIC status would impose severe tax consequences on U.S. shareholders. POET stock fell $0.59, or 8.08%, closing at $6.71. The securities action alleges the Company’s prior risk disclosure had failed to warn investors that PFIC classification would materially reduce demand for the stock.
April 21, 2026: The Stocktwits Interview and Alleged NDA Breach
The Company’s executive vice president and chief financial officer appeared on a Stocktwits interview on YouTube. During the broadcast, as claimed in the complaint, he publicly identified business relationships and disclosed purchase order and shipping details. The action contends these statements violated confidentiality obligations with Marvell Semiconductor, setting in motion the cancellation that would devastate the stock days later.
April 27, 2026: Cancellation and the 47.3% Crash
Before the market opened at 8:58 AM ET, POET announced that Marvell had cancelled all purchase orders from Celestial AI, citing the Company’s breach of confidentiality obligations. Shares plunged from $15.10 to close at $7.95, a single-day loss of $7.15 per share.
