Cornerstone Building Brands, Inc. 8-K

What Happened
Cornerstone Building Brands, Inc. filed an 8-K reporting that Jeffrey Lee, Executive Vice President and Chief Financial Officer, informed the company on December 29, 2025 that he will resign to accept another professional opportunity. Mr. Lee will continue in his role through February 6, 2026. The company said his resignation was not due to any disagreement with the company’s operations, policies or procedures and that it will commence an executive search for a new CFO.

Key Details

• Jeffrey Lee notified the company of his decision on December 29, 2025.
• Resignation effective date: February 6, 2026.
• Reason given: to accept another professional opportunity; not related to any conflict or disagreement with the company.
• Cornerstone will begin an executive search for a successor (no interim CFO or successor named in the filing).

Why It Matters
A CFO departure is a material leadership change that investors should note because it can affect financial oversight and investor confidence. In this case, the company has short-term continuity—Mr. Lee will remain in his role until February 6, 2026—and has initiated a search for a replacement. Investors should watch for follow-up disclosures (appointment of a successor, any interim arrangements, or related changes) in future filings or press releases.
