Solaris Energy Infrastructure's board appointed Stephan E. Tompsett as Chief Financial Officer effective February 12, 2026, replacing Kyle Ramachandran, who had held the role since the company's initial public offering. Ramachandran remains President and head of the Solaris Power Solutions segment, and the filing says Tompsett's compensation terms are still being finalized and will be disclosed later.
