The TellerScore is our own summary of the figures this institution reports publicly; it is not issued or endorsed by any government agency. It is not a prediction, and deposits within insurance limits are protected either way.

The score has been essentially flat from Q2 2025 to Q2 2026 (93 → 93).

Percentile against banks of similar size nationwide (100th = best among peers; for ratios where lower is better, the scale is flipped).
