Nucor Corporation (NYSE: NUE) filed a Form 8-K on December 4, 2025 to announce a leadership succession.
David A. Sumoski, Chief Operating Officer since 2021 and age 59, notified the Board on December 2, 2025 that he will retire. He steps down as COO on January 1, 2026, remains an Executive Vice President as an advisor to Chair and CEO Leon J.
Topalian, and retires on June 13, 2026. The filing says his decision is voluntary and in line with the Company's succession planning. Stephen D.
Laxton, the Company's Chief Financial Officer and Executive Vice President since 2022, was appointed President and Chief Operating Officer effective January 1, 2026. Mr. Topalian continues as Chair and CEO. Mr. Laxton will remain CFO until a successor is appointed, and the company says it will conduct a search for a new CFO.
His annual base salary will increase to $1,000,000a effective January 1, 2026. He will continue to participate in the Senior Officers Annual Incentive Plan, the Senior Officers Long-Term Incentive Plan (with awards for in-progress performance periods pro-rated for the salary increase), and the Supplemental Retirement Plan for Executive Officers, and remains eligible for equity awards under the 2025 Omnibus Incentive Compensation Plan.
For investors, the filing is primarily a management transition: a planned operational leadership change with a long-tenured executive stepping back and an internal successor elevated. The filing discloses no financial results, and the CFO vacancy that follows Mr. Laxton's move is the main open item to watch.
