Positive

• Sale explicitly for tax withholding on RSU vesting, not a discretionary cash‑out

• Weighted average price disclosed with offered breakdown for audit transparency

Negative

• Sale reduces insider holdings by 9,653 shares, a measurable but limited dilution of that insider stake

Insights

Corporate Governance Analyst

Officer sold shares via a pre‑arranged plan to meet tax obligations on vested RSUs.

The transaction shows a routine sell‑to‑cover execution under a Rule 10b5‑1 style durable instruction adopted on 04/09/2024, which typically reduces insider timing risk because trades are pre‑scheduled and non‑discretionary. The sale of 9,653 shares at a weighted average of $11.03 was explicitly for tax withholding on RSUs vested 10/01/2025.

Key dependencies include the continued use of the automatic sale instruction and future RSU vesting schedules; investors can monitor subsequent Form 4 filings for additional pre‑arranged sales or discretionary trades within the next 30–90 days.

Equity Compensation Specialist

Sale size is modest relative to retained holdings, indicating no major de‑risking.

After the reported sale the reporting person still beneficially owns 194,440 shares, so the disposition represented a small portion of total holdings and specifically addressed tax withholding rather than liquidity or diversification. The weighted average sale price range ($10.99–$11.0697) is shown for transparency and the filer offers to provide a price-by-price breakdown if requested.

Watch for the number and timing of future sell‑to‑cover transactions tied to RSU vesting dates such as the recent 10/01/2025 vesting; changes in the automatic plan terms would appear on amended filings.
