Key Details

• Transaction date: August 15, 2026 (filed with the SEC on August 18, 2026).
• Grant: 450,000 DSUs granted at $0.00 per share (each DSU equals a contingent right to one share).
• Tax withholding: 7,070 shares withheld/removed at $0.31 per share for ~$2,192 (tax payment on vesting/settlement). Footnote F3 confirms shares were withheld to pay tax withholding obligations.
• Vesting schedule (footnote F1): The 450,000 DSUs vest in four equal installments of 112,500 shares on Aug 15 of 2027, 2028, 2029 and 2030, conditioned on continued employment; settlement of vested DSUs is deferred per the DSU agreement.
• Holdings noted (footnote F2): Filing discloses an aggregate of 944,758 shares issuable upon vesting/settlement of RSU/DSU awards under the 2023 plan, plus 22,250 shares issuable under the 2018 plan (these are subject to future vesting).

Context This filing reflects a compensation grant (DSUs) rather than an open-market purchase or sale; DSUs are common executive compensation and do not require the insider to pay for shares now. The small share disposition was a tax-withholding action, not a market sale. The filing includes standard vesting and deferred settlement terms; no 10b5-1 plan or other sale program is indicated.
