MARA Holdings Appoints Craig Hart and Nancy Novak to Board After Two Resignations

Neutral Impact 2 of 5 leadership Written later

MARA Holdings said directors Barbara Humpton and Georges Antoun resigned from the board effective July 31, 2026, citing personal reasons and no disagreements with the company. On August 1, 2026, the board appointed Craig Hart and Nancy Novak to fill the two vacancies, with Hart also joining the Risk and Audit Committee. The board will still have seven directors, six of whom are independent, so the change is administrative and does not signal a shift in financial results.

Key points

  • Barbara Humpton and Georges Antoun resigned from the board, effective July 31, 2026, for personal reasons.
  • Craig Hart and Nancy Novak were appointed directors on August 1, 2026, effective immediately.
  • Hart succeeds Antoun on the Risk and Audit Committee; the board will have seven directors, six independent.
  • Hart is a Senior Portfolio Manager at Avenue Capital Group; Novak previously was Chief Innovation Officer of Compass Datacenters.
