Director Williams Eugene purchased 2,000 shares of PMN at $24.40 on 2026-03-05, expanding holdings to 12,397 shares.
Williams Eugene, a director of ProMIS Neurosciences, purchased 2,000 shares at $24.40, increasing his stake by 19.2% to 12,397 shares. The transaction occurred after three consecutive open-market buys on 2026-03-02, 2026-03-03, and 2026-03-04—a concentrated buying pattern over four consecutive trading days. The stock now trades at $23.40, down 16.4% from its 52-week high of $28.00 despite a 49.5% gain over the preceding 30 days. Against this backdrop of fundamental headwinds—the company is unprofitable with net income of $-11,580,126.00 and a P/E ratio of 212.73—the director's rapid accumulation suggests a conviction in near-term upside, though prior same-ticker outcomes are not yet measurable.
