The Form 4 reports the acquisition price as $0.00 (derivative award), indicating a stock option award rather than an open‑market purchase or sale.

Key Details

• Transaction date: 2026-03-06; Form 4 filed: 2026-03-09 (appears timely).
• Reported transaction: A (award/grant) — 490,500 shares; reported price $0.00 (derivative).
• Vesting (per footnote): granted under the Issuer’s 2024 Equity Incentive Plan. 25% vests on October 20, 2026, with the remaining shares vesting in 36 equal monthly installments thereafter (four-year vesting schedule).
• Shares owned after the transaction and any exercise price/fair‑value details are not specified in the filing.

Context

• This is a compensation-related option grant (derivative award). Such grants typically vest over time and do not represent immediately tradable shares until vested and, if required, exercised. This is neither an open‑market purchase (bullish signal) nor a sale; it reflects standard equity compensation for executives.
