Analysis · STBA · Finance
Record quarterly EPS of $1.09 came in 6.9% above 2Q26 and 19.8% above 3Q25, helped by buybacks that have retired 8.3% of shares since repurchases began in 4Q25. The more useful detail for the thesis is the margin: net interest margin (FTE) widened 7 basis points to 4.06% as asset yields rose 9 basis points to 5.73%, and the efficiency ratio improved to 53.23% from 55.52%. Credit is mixed rather than clean — nonperforming assets fell $3.7 million to $36.5 million (0.45% of loans plus OREO), but net charge-offs doubled to $2.1 million, or 0.10% of average loans, from 0.05% in 2Q26. Capital remains well above well-capitalized thresholds with CET1 at 14.02%, and no buybacks were executed in the quarter, leaving the $100 million program authorized in July as dry powder.
