Minor SEC amendment clarifies internal control signoffs; audited results unchanged.

Grupo Simec filed an amendment to its Annual Report on Form 20-F to add separate conclusions from its principal executive officer and principal financial officer on the effectiveness of disclosure controls and internal control over financial reporting as of October 02, 2025.

The amendment does not change audited financial statements or other Form 20-F sections, so the update is a compliance and disclosure correction rather than a substantive financial event. The primary dependency is continued clear disclosures from management and the company’s internal control environment remaining unchanged.

Watch for any future filings that revise audit opinions or restate financials; near-term horizon: the next periodic SEC filing or any auditor communication within Q4 2025.
