MIZELL STEVEN 4

What Happened

This transaction is an award/grant (code A) — not an open-market purchase or sale — and is typically a form of director compensation rather than a trading signal.

• Award type: 5,491 DSUs granted under the 2024 Equity Incentive Plan in lieu of 5,491 restricted stock units.
• Vesting: DSUs vest in full on the earlier of (i) June 18, 2027 or (ii) the date of the next annual meeting of stockholders, subject to continued service. Each DSU equals the right to receive one share at settlement.

• Filing timeliness: Form was filed within the normal SEC reporting window (no late filing indicated).

Context

• DSUs are deferred equity awards that convert to shares (or cash tied to share value) at settlement; they are commonly used for director compensation and do not reflect an immediate market purchase or sale.
• Because this is an award to a director (not a sale), it’s generally treated as routine compensation rather than an actionable buy/sell signal for investors.
