AI brief of an SEC Form 8-K · Clean Harbors (CLH)

Clean Harbors adds co-CEOs Battles and Gerstenberg to board, expanding it to 13 members

Neutral Impact 3 of 5 leadership Written later

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. The filing does not change either executive's role, and neither will receive extra pay for board service, so the direct effect on shareholders is limited to governance.

Key points

  • 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.
  • Neither director was appointed to a board committee, and neither will receive additional compensation for board service.
  • Founder and Executive Chairman Alan S. McKim said the co-CEOs' first year and a half in charge had been successful for the Company, its employees and its shareholders.

Written later: this filing was briefed after the fact, when past filings were added to the site, so the brief may be read with hindsight; the filing itself is the record of what was known on September 03, 2024.

Briefs are written by AI from the filing text (each brief's own page names the model) and can contain mistakes — open the filing before acting on anything. Impact (1-5) and tone are the model's reading of the filing for shareholders, not a price forecast. Not investment advice.
