Context

• Sell-to-cover transactions are routine administrative trades to satisfy tax obligations when equity awards vest and generally do not indicate the insider’s discretionary view of the stock. This filing documents tax-driven sales of vested RSUs rather than an independent decision to liquidate additional holdings.
