• Option exercises fully vested, indicating no early-exercise irregularities
• Detailed sale price ranges disclosed with offer to provide per-price detail to the Commission

Negative

Insights

Corporate Governance Analyst

TL;DR: Routine, plan-driven insider activity with disclosed tax-driven sales and option exercises.

The reported transactions indicate an officer used a pre-established 10b5-1 trading plan to execute sales and option exercises on 10/06/2025–10/07/2025

This reduces signalling risk because trades were pre-planned; monitor future filings to confirm no pattern of opportunistic sales within earnings blackout windows.

Compensation & Equity Specialist

TL;DR: Option exercises were fully vested and sales partially covered tax from RSU vesting.

The filing shows exercises of 1,785 options at $6.28 and 10,708 at $9.46, described as fully vested, and a sale of 8,134 shares to satisfy tax withholding on vested RSUs.

Key near-term items to watch include future vesting schedules for the 452,622 restricted stock units and any subsequent Form 4s showing planned dispositions or additional option exercises.
