First Guaranty Bancshares (FGBI) surged 15.76% in after-hours trading following reports of substantial insider buying on Dec. 31, 2025. The purchases, highlighted in multiple news outlets, signaled strong insider confidence in the company’s turnaround strategy despite a third-quarter 2025 loss. This activity reshaped market sentiment, with investors interpreting the insider accumulation as a credible sign of undervaluation and improving fundamentals. The bullish move occurred amid mixed earnings expectations, as the stock faces a projected 1,066.7% year-over-year earnings decline for the upcoming quarter. However, the insider transactions overshadowed near-term financial concerns, driving renewed buying interest. The surge aligns with the disclosed news, reinforcing the transaction’s direct link to the after-hours price action.
