James Hardie Industries plc appointed David Hill, the Company's Vice President of Finance Integration and Transformation, to succeed David Wisniewski as the Company's Chief Accounting Officer, effective March 17, 2026. The transition is not due to any disagreement between Mr. Wisniewski and the Company or its Board regarding any matter related to the Company's accounting principles or practices, financial disclosures, or internal controls. Mr. Hill previously held the title of Vice President and Global Controller from 2016 until 2025 before transitioning into leading the finance integration efforts related to the Company's acquisition of The AZEK Company Inc. Prior thereto, Mr. Hill served in a variety of roles at Mars Corp., United Service Companies, Hyatt Hotels and Ernst & Young.
Mr. Hill is a certified public accountant (inactive) and has more than fifteen years of experience in accounting and finance with publicly traded companies. To help facilitate a smooth transition, it is expected that Mr. Wisniewski will remain with the Company in an advisory role for a period of time.
