Class action lawsuit filed against POET Technologies after stock plunge on lost Marvell orders

Pomerantz LLP has filed a class action lawsuit against POET Technologies following a sharp 47% drop in its stock price after Marvell Semiconductor canceled all purchase orders from Celestial AI, a POET customer. The lawsuit alleges securities fraud and unlawful business practices by POET and its officers related to the disclosure of confidential order information. Investors who bought POET shares during the class period have until June 29, 2026, to join the lawsuit or seek lead plaintiff status. This legal action highlights risks tied to POET's business dealings and recent negative market reaction.
