Neutral leadership Written later 5.027.01

Clean Harbors said on September 3, 2024 that it expanded its board from eleven to thirteen members and elected Co-Chief Executive Officers Michael Battles and Eric Gerstenberg as directors, effective immediately.

  • Board expanded from eleven to thirteen members; both new directors are Class III directors whose terms expire at the 2025 annual meeting.
  • Battles has been Co-CEO since 2023 and was CFO from 2016; Gerstenberg has been Co-CEO since 2023 and was COO since 2015.
