Key Details

• Transaction date and price: 2026-03-10; 9,258 shares at $23.70 each (total $219,415).
• Filing date / timeliness: Form 4 filed 2026-03-12 (appears timely, two days after the transaction).
• Shares owned after transaction: Not specified in the provided filing details.
• Notable footnotes:
  • F1: Shares were withheld by the issuer to satisfy the reporting person's tax withholding/remittance obligations and do not represent a sale by the reporting person.
  • F2: The shares reported include unvested restricted stock units (RSUs).
• Transaction code: F (payment of exercise price or tax liability via share withholding/net settlement).

Context
This was a tax-withholding/net-settlement of RSUs rather than a purchase or a discretionary sale; such withholdings are routine and do not necessarily indicate the insider's view on the company. As a reported 10% owner, Shea Thomas is a significant shareholder; the transaction reflects internal compensation settlement mechanics rather than an investment decision.
