Insights

Corporate Governance Analyst

Baxter announces COO resignation, eliminates the COO role, and CEO assumes interim leadership of MPT. Governance shift with execution focus implications.

Baxter International Inc. disclosed that Heather Knight will resign as Executive Vice President and COO and as interim group president of Medical Products and Therapies (MPT), effective October 29, 2025. As of that date, the company will no longer have a COO. CEO Andrew Hider will serve as interim group president of MPT.

This is a governance and operating model change. Removing the COO role concentrates operating oversight under the CEO and adds interim responsibility for MPT. That can streamline decisions, but it also centralizes accountability in one office. The filing does not describe changes to strategy, reporting lines, or compensation, so the immediate effect is structural rather than financial.

Key items to watch: whether Baxter appoints a permanent MPT leader and how responsibilities are redistributed after October 29, 2025. Also monitor future disclosures for any revisions to segment oversight or additional leadership changes. Near term, look for follow-up in the next periodic report or a subsequent 8-K addressing permanent appointments and any organizational adjustments.
