Xylem Inc. Appoints D. Christian Koch to Board of Directors

What Happened

• Xylem Inc. announced on August 13, 2026 that its Board of Directors increased from 9 to 10 members and appointed D. Christian Koch to fill the new seat, effective immediately.
• The Board named Mr. Koch to the Leadership Development and Compensation Committee and the Nominating and Governance Committee and determined he is independent under Xylem’s governance policies, NYSE standards, and SEC rules.
• Mr. Koch currently serves as Chairman, President and Chief Executive Officer of Carlisle Companies Incorporated. Xylem disclosed there are no agreements or related‑party transactions requiring Item 404(a) disclosure. His director pay will follow Xylem’s standard non‑employee director compensation and will be prorated for the current term. A press release announcing the appointment was filed as Exhibit 99.1.

Key Details

• Board size increased from 9 to 10 directors; appointment effective August 13, 2026.
• Committees: Leadership Development & Compensation; Nominating & Governance.
• Independence: Board concluded Mr. Koch meets Xylem, NYSE and SEC independence standards.
• Compensation: Standard non‑employee director package per Xylem’s 2026 Proxy Statement; prorated for current term. No reportable related‑party transactions.

Why It Matters

• This is a governance change that alters board composition and adds an independent director with current CEO experience at another public company.
• Mr. Koch’s assignments to the compensation and governance committees mean he will participate directly in oversight of executive pay and board nominations.
• For investors, the filing is principally a routine director appointment and governance update; it does not report financial results or disclose material related‑party transactions.
