Summary
Summary of the 8-K filed November 10, 2025. Cited figures are marked; the original filing is the authoritative source.
AMETEK, Inc. (NYSE: AME) filed an 8-K on November 10, 2025 to disclose a senior finance leadership transition.
Thomas M. Montgomery, Senior Vice President, Comptroller and Principal Accounting Officer, will retire effective January 1, 2026, after 42 years with the company, and will remain as a Senior Advisor through 2026. Robert J.
Amodei, currently Vice President and Assistant Controller, will succeed him as Senior Vice President, Controller and Principal Accounting Officer effective the same date. Amodei has been with AMETEK for 36 years and holds CPA and CGMA credentials, and he will be an executive officer in his new role. The filing also covers a related promotion.
Scott M. DelOrefice, currently Divisional Vice President, Finance for the Engineered Materials, Interconnects & Packaging division, will become Vice President, Group Controller of the Electromechanical Group effective January 1, 2026. DelOrefice has eight years with AMETEK and previously served as CFO of Asahi Refining North America.
For investors, this is a planned, orderly succession announced well ahead of the effective date rather than a disruptive departure. The 8-K contains no financial results, guidance, or changes to the company's accounting policies, and the announcement is framed by management as evidence of internal talent depth. The filing does not disclose any compensation changes for the new officers, so the primary near-term significance is continuity in the finance organization, which is a modest positive for governance and execution.
