| Net interest income after credit loss expense totaled $236.4 million for the second quarter of 2026, compared to $223.4 million in the first quarter of 2026, an increase of 5.8%. The increase was driven by continued growth in earning assets, including the impact of the Mountain Commerce acquisition completed during the quarter, as well as favorable net interest margin performance. | Non-interest income totaled $53.5 million for the second quarter of 2026, compared to $42.8 million in the first quarter of 2026, an increase of 24.9%. The increase was primarily driven by higher other service charges and fees, a favorable fair value adjustment on marketable securities, and growth in other income, with additional contributions from the completed acquisition of Mountain Commerce. | |||||||

Total revenue (net) reached a Company-record $295.1 million for the second quarter of 2026, increasing 10.6% from $266.7 million in the prior quarter. The increase was driven by strong growth in net interest income, including the contribution from the Mountain Commerce acquisition completed during the quarter. The acquisition further enhances the Company's earnings capacity and positions it well for continued revenue growth and earnings accretion in future periods. | Total expenses increased during the second quarter of 2026, reflecting the completed acquisition of Mountain Commerce. Interest expense increased to $95.2 million from $87.1 million in the prior quarter, primarily due to higher interest on deposits resulting from a $921.3 million increase in interest-bearing deposits. Non-interest expense increased to $135.5 million from $114.0 million in the first quarter of 2026, driven primarily by $12.7 million of merger-related expenses incurred during the quarter. | |||||||

The efficiency ratio was 44.54% for the second quarter of 2026, compared to 41.59% in the prior quarter, primarily reflecting $12.7 million of merger-related expenses associated with the completed acquisition of Mountain Commerce.

The decline was primarily attributable to $12.7 million of merger-related expenses associated with the completed acquisition of Mountain Commerce. Excluding merger-related expenses and certain other non-GAAP adjustments, ROA, as adjusted, (non-GAAP)(1) remained strong at 2.09%, reflecting the Company's continued earnings strength and operating performance. | |||||||
