Summary

Plumas Bancorp reported record second-quarter 2026 earnings of $9.9 million, or $1.43 per share, a 58% increase from the prior-year quarter. The strong performance reflects the July 2025 acquisition of Cornerstone Community Bank, which added $658 million in assets and drove 49% loan growth and 38% deposit growth year-over-year.

Net interest income jumped 43% to $26.0 million, while net interest margin expanded 30 basis points to 5.13%, benefiting from higher loan yields, repricing of the portfolio, and discount amortization on acquired loans. Asset quality metrics deteriorated modestly: nonperforming assets rose to 1.04% of total assets from 0.84%, and nonperforming loans increased to 1.55% of total loans from 1.34%.

The allowance for credit losses as a percentage of loans declined to 1.30% from 1.39%, though the absolute reserve grew to $19.7 million from $14.2 million. The company returned $12 million to shareholders through dividends and buybacks while growing book value per share 20% to $39.08. The integration of Cornerstone appears to be driving meaningful earnings accretion and margin expansion, though the uptick in nonperforming loans warrants monitoring as the acquired portfolio seasons.
