George Christopher Kile 4

What Happened
George Christopher Kile, EVP & CFO of Select Water Solutions, received 25,674 shares on March 5, 2026 that represent performance share units (PSUs) that vested. To satisfy tax withholding on the vesting event, 10,103 of those shares were withheld (disposed) at an indicated per-share value of $14.03, totaling $141,745. The award line in the filing shows an acquisition value of $0.00 because these were earned PSUs rather than a cash purchase.

Context
This was a vesting of previously granted performance awards, not an open‑market purchase or sale for investment purposes. Withholding shares to cover taxes is a common administrative step and does not necessarily indicate a change in the insider’s market view. Transaction codes: A = award/acquisition (PSU vesting); F = tax withholding (share disposition).
