Key Details

• Transaction date: March 1, 2026; Form 4 filed March 3, 2026 (timely — within the 2-business-day reporting window).
• Awards: 21,444 and 28,871 shares granted (awards shown at $0.00 per share because they are compensation grants).

• Footnotes: Awards granted under Solaris’ Long Term Incentive Plan; PSUs from prior grants (3/1/2023, 3/1/2024, 3/1/2025) vested and were settled based on performance. 63,581 Class A shares remain subject to future vesting per the filing.

Context

• This action reflects vesting and settlement of compensation awards, not an open‑market investment sale or purchase. The withholding of shares to cover taxes is a common administrative step (cashless/tax‑satisfaction) and does not necessarily indicate a decision to sell for investment reasons.
• PSUs settled here were performance‑based — their final share amount depended on Solaris’ achievement of specified goals.
