Multiple Plaintiff Firms Race to Lead POET Technologies Securities Lawsuit

A June 29, 2026 deadline will decide who leads a suit that alleges POET hid a likely PFIC designation that could raise taxes and reporting burdens for U.S. investors.

Overview

Law firms including Rosen, the Schall Law Firm and DJS have issued notices this week urging POET shareholders to seek lead-plaintiff status in a securities complaint covering purchases from April 1 to April 27, 2026.
The complaint, first filed in early June, alleges POET misrepresented the likelihood it would be treated as a passive foreign investment company, a tax status that can trigger higher taxes and complex annual reporting for U.S. holders.
Plaintiffs also accuse CFO Thomas Mika of breaching a business agreement by publicly discussing company deals, which the suit says harmed POET’s business prospects and contributed to investor losses.
No class has been certified and the allegations remain unproven; whose motion succeeds by June 29 will control litigation strategy and the next court filings.
If investors were harmed, the case could lead to recoveries for affected shareholders and raise scrutiny of how small foreign-listed firms disclose tax risk to U.S. investors.
