What Happened
Acadia Healthcare filed an 8-K reporting that director Wade Miquelon informed the board on March 9, 2026 that he will retire and will not stand for reelection at the Company’s 2026 annual meeting. On March 12, 2026 the board increased its size and appointed Daniel (Dan) Cancelmi as a Class III director effective immediately; Mr. Cancelmi will serve on the Audit Committee. The board also approved reducing the board size back upon Mr. Miquelon’s retirement at the 2026 annual meeting. A press release announcing these changes was issued March 12, 2026.

Key Details

• Wade Miquelon notified the board on March 9, 2026 and will retire effective at the Company’s 2026 annual meeting; he said his decision was not due to any disagreement with the Company.
• On March 12, 2026 the board increased its total members from 10 to 11 and increased Class III directors from three to four to appoint Daniel Cancelmi; Class III terms expire at the 2026 annual meeting.
• Mr. Cancelmi will join the Audit Committee and will be compensated under Acadia’s existing non‑employee director compensation plan (as described in the Company’s 2025 proxy).
• The board confirmed there are no special arrangements, family relationships, or transactions involving Mr. Cancelmi that require Item 404 disclosure.

Why It Matters
Board turnover and appointments affect corporate governance and committee oversight. This filing signals an orderly transition (retirement, not a disagreement) and immediate reinforcement of the Audit Committee with a new independent director. Investors should note the timing (appointment March 12, 2026; retirement effective at the 2026 annual meeting) and that director compensation follows the company’s established plan.
