Health Catalyst reduces the size of the Board

Health Catalyst (HCAT) announced actions to reduce the size of the Board. Dawn Smith and Duncan Gallagher stepped down from the Board, effective February 17 and John Kane will step down on April 1. These changes are in addition to the planned departure of Matt Kolb, who previously notified the Company that he will not seek reelection as a director at the 2026 Annual Meeting of Shareholders and will complete his board service immediately prior to the 2026 Annual Meeting. As a result of these changes, the size of the Board has been reduced at the effective time of each of the departures and will ultimately be set at five directors immediately prior to the 2026 Annual Meeting. Health Catalyst is grateful for the contributions and service of the departing directors. In addition, Spencer has been elected to serve as Chair of the Board. Matt Arens has been named Chair of the Nominating and Corporate Governance Committee, which now consists of Arens and Jill Hoggard Green; Julie Larson-Green will continue to serve as Chair of the Compensation Committee; and Mr. Kane will continue to serve as Chair of the Audit Committee until his departure. The Audit Committee now consists of Kane, Spencer, and Larson-Green.
