Summary
WhiteFiber executed a planned CFO transition on August 1, 2026. Erke Huang resigned as CFO and board member but remains engaged as senior advisor and non-voting board observer through August 2027 under a transition services agreement with Bit Digital, where he continues as CFO. The filing explicitly states his departure involved no disagreement with the company.
Justin Zhu, who has served as Senior VP of Finance since the company's August 2025 IPO, was promoted to CFO with a two-year employment agreement. The board added two directors: CEO Sam Tabar, who has led the company since February 2025, and Michael Rulf, an independent director with cloud services expertise who joins the Compensation and Nominating Committees.
The changes strengthen board governance by adding management representation and expanding independent oversight. Existing independent director Pruitt Hall received an 80% compensation increase to $270,000 annually, reflecting his committee responsibilities. For retail holders, the transition appears orderly. Huang's advisor role provides continuity, Zhu has institutional knowledge from the IPO process, and the board expansion adds technical expertise. The CFO change is material but structured to minimize disruption.
