Solaris Energy (SEI) CAO sheds 1,303 shares as RSU tax, holds 34,782

Rhea-AI Filing Summary

Solaris Energy Infrastructure, Inc.’s Chief Accounting Officer Christopher P. Wirtz reported a routine tax-related share disposition. The company withheld 1,303 shares of Class A common stock at $69.54 per share to cover tax obligations triggered by the vesting of previously granted Restricted Stock Awards.

After this withholding, Wirtz directly holds 34,782 shares of Class A common stock, including 12,443 shares from earlier Restricted Stock Awards that are still subject to vesting. This event reflects compensation-related tax settlement rather than an open-market stock sale.

Insights

Equity compensation and governance analyst

Routine tax withholding on equity vesting; no open-market selling signal.

The filing shows Solaris Energy Infrastructure’s Chief Accounting Officer had 1,303 Class A shares withheld at $69.54 per share to satisfy tax obligations arising from vesting Restricted Stock Awards. Code F transactions are mechanical and tied to compensation, not discretionary trading decisions.

Following the event, he holds 34,782 shares, including 12,443 unvested Restricted Stock Award shares. Because this is a tax-withholding disposition rather than a market sale or purchase, it provides limited insight into his view of the stock or the company’s fundamentals.
