WYMAN WILLIAM W 4

What Happened

• William W. Wyman, a director of ProMIS Neurosciences, was granted derivative awards totaling 16,500 shares on May 20, 2026. The filing reports two awards: 5,500 shares and 11,000 shares, each recorded at $0 on Form 4 (derivative securities rather than an open‑market purchase).

Key Details

• Transaction date: May 20, 2026; Form 4 filed May 22, 2026 (appears timely under the two-business-day rule).
• Awards: 5,500- and 11,000-share derivative grants; reported price/value on the Form 4: $0 (these are awards/options/RSUs, not a cash purchase).
• Vesting (from filing footnotes):
  • 5,500-share award: vests in full on May 20, 2027, subject to continued board service (F1).
  • 11,000-share award: 25% vested on grant; remaining shares vest ratably over 36 months, subject to continued service (F2).
• Shares owned after the transaction: not specified in the Form 4 filing.
• Filing status: timely (filed two days after the transaction date).

Context

• These were awards (derivative grants), not purchases or sales. Such grants are commonly used for director compensation and do not by themselves indicate buying or selling for investment purposes.
• Because the awards vest over time (and some portions are not immediately vested), they may not be freely tradable until vesting conditions are met.
