MARA Holdings: Two Board Members Resign; Novak and Hart Appointed

What Happened

• MARA Holdings, Inc. filed an 8-K (Aug 4, 2026) announcing that directors Barbara Humpton and Georges Antoun notified the board of their resignations on July 29 and July 30, 2026, respectively, effective July 31, 2026. The board accepted their resignations, which the directors said were for personal reasons and not due to any disagreements with the Company.
• On August 1, 2026 the board appointed Nancy Novak and Craig Hart as directors, effective immediately. Mr. Hart was also named a member of the Board’s Risk and Audit Committee, succeeding Mr. Antoun.

Key Details

• Resignations effective: July 31, 2026 (Humpton, Antoun). Appointments effective: August 1, 2026 (Novak, Hart).
• Director terms: Nancy Novak will serve as a Class I director through the 2027 annual meeting; Craig Hart will serve as a Class II director through the 2028 annual meeting.
• Backgrounds: Craig Hart is Senior Portfolio Manager and Global Co‑Head of Energy and Power at Avenue Capital Group with 25+ years in energy and power; Nancy Novak is an experienced leader in hyperscale data center development and construction with 40+ years in mission‑critical infrastructure.
• Governance/compensation: Both new directors are eligible for the company’s non‑employee director compensation program and will enter indemnification agreements; a press release announcing the appointments was furnished as Exhibit 99.1 to the 8‑K.

Why It Matters

• The board turnover changes MARA’s governance composition and committee membership (Risk and Audit Committee), which investors watch for oversight of financial reporting, risk management and strategic decisions.
• The new directors bring experience in energy/power and data‑center infrastructure — areas that can be relevant to companies with significant infrastructure or energy considerations. Investors may want to note the timing of terms (2027 and 2028 annual meetings) and consult future filings or proxy materials for any further governance or compensation disclosures.
