Insights

Banking Regulatory Analyst

Late 10-Q tied to late-September events; financials and disclosures under revision.

**First Guaranty Bancshares, Inc.** filed an NT 10‑Q on November 10, 2025, stating it could not timely file its quarterly report for the period ended September 30, 2025. The company is revising financial information and disclosures to reflect the impact of events that occurred in late September and were referenced in an earnings release attached as Exhibit 99.1 to a Form 8‑K filed on October 31, 2025.

This indicates the quarter’s reported figures and/or narrative disclosures require updates due to those events. An NT 10‑Q provides a short grace period under Rule 12b‑25, but the filing here emphasizes that timely completion would have required unreasonable effort. The need to revise financial information suggests the events had a non‑trivial impact on the quarter’s reporting.

Watch for the forthcoming Form 10‑Q to detail the revisions, including any changes to income statement, balance sheet, or risk disclosures tied to late‑September events. The key near‑term marker is the company’s 10‑Q filing following the NT dated November 10, 2025, and any alignment with the October 31, 2025 earnings release narrative.
