Tompsett Stephan E 4

What Happened

• Stephan E. Tompsett, Chief Financial Officer of Solaris Energy Infrastructure, Inc. (SEI), was granted 30,000 shares of Class A common stock as a Restricted Stock Award on February 12, 2026. The grant price is reported as $0.00, so the reported acquisition value is $0. The award is coded as an "A" (award/grant).

Key Details

• Transaction date: 2026-02-12; Form 4 filed: 2026-02-17 (appears timely under the 2-business-day rule).
• Shares granted/acquired: 30,000 restricted shares at $0.00; reported acquisition value $0.
• Vesting: Vests in three equal annual installments on the first three anniversaries from March 1, 2026 (i.e., vesting dates begin March 1, 2027).
• Holdings: Footnote indicates these 30,000 shares are subject to vesting and are included in the insider’s holdings that remain subject to vesting (the filing does not state a final total of shares owned free of restrictions).
• Transaction code: A = Award/Grant; no 10b5-1 plan, tax withholding, or cashless sale noted.

Context

• Restricted stock awards are a common long-term incentive for executives; because the shares vest over multiple years, they are not immediately liquid and do not necessarily signal an immediate trading intent. This grant increases Tompsett’s potential future stake if vesting conditions are met.
