What Happened

• The transaction is reported as a sale (S) but is a "sell-to-cover" tied to the vesting of Restricted Stock Units (RSUs), meaning the shares were sold to cover tax withholding and do not reflect a discretionary trade.

Key Details

• Transaction date and price: 2026-02-13 — 2,184 shares at $48.26 each (≈$105,402).
• Transaction type/code: Sale (S); footnote confirms this was a tax withholding "sell to cover" (not a discretionary sale).
• Shares owned after transaction: Not specified in the provided filing excerpt.
• Beneficial ownership note: The Reporting Person and spouse are sole trustees and beneficiaries of the Chess 1997 Trust (per footnote).

Context

• Sell-to-cover transactions are routine when RSUs vest; they are executed to satisfy tax obligations and generally do not signal the insider’s view on the company.
• For retail investors, purchases or open-market buys by insiders tend to carry more informational weight than routine withholding sales.
