Health Catalyst Appoints Tami Reller to Board; Board Expanded to Seven

What Happened

• Health Catalyst, Inc. filed an 8-K reporting that on September 11, 2026 the board (following the Nominating and Corporate Governance Committee’s recommendation) appointed Tami Reller to the board, effective October 1, 2026. Her appointment fills a newly created seat as the board expands from six to seven directors. Ms. Reller will serve as a Class III director until her successor is elected or she otherwise leaves the board.
• The board also appointed Ms. Reller to the Audit Committee (as chair, replacing Justin Spencer, who will remain a committee member) and to the Compensation Committee, replacing Jill Hoggard Green on those committee roles. She will receive cash and equity under the company’s non-employee director compensation policy and will enter the company’s standard indemnification agreement.

Why It Matters

• The appointment adds an experienced healthcare, technology and finance executive to the board and places her in charge of the Audit Committee, which oversees financial reporting and controls—an important governance change for investors evaluating oversight and risk management.
• The board expansion and committee reshuffle are governance updates that may influence board dynamics and oversight going forward. The filing notes standard director compensation and indemnification and discloses no related-party transactions or family ties.
