POET Technologies Faces Shareholder Claims Its Investment Story Was Out of Tune

POET Technologies told investors it was positioned for the AI chip race. Big customers. Major purchase orders. Strong growth ahead.

But according to the complaint, the story behind the scenes was falling apart.

In March 2026, POET disclosed it may be treated as a PFIC. The complaint claims that disclosure understated the likelihood and the risk to U.S. shareholders.

Then in April, a short-seller report alleged POET had created an IRS nightmare for U.S. investors. The stock fell.

Days later, POET tried to calm the market. Its CFO also told investors POET had a Celestial AI invoice and expected to sell product to Marvell and Celestial AI.

But on April 27th, POET announced Marvell had canceled all Celestial AI purchase orders, saying POET had disclosed purchase-order and shipping information in violation of confidentiality obligations.

Investors were stunned. The stock plunged about 47% in a single day.

Now, POET investors are learning more about the lawsuit.
