1 This is a non-GAAP financial measure. See financial tables for a reconciliation of non-GAAP financial measures to GAAP financial measures.



Based on our latest forecasts for balance sheet growth and mix, and current market conditions, we continue to expect total net interest income growth of 14% to 15% in 2025.

Taxes
Third quarter 2025 tax expense was $30 million, compared to $28 million of tax expense in the prior quarter and $20 million of tax expense in the same period last year. The effective tax rate for the third quarter of 2025 was 19.16%, compared to 20.34% in the prior quarter and 18.61% in the same period last year.

The allowance for credit losses on loans (ACLL) of $415 million increased $3 million compared to the prior quarter and increased $17 million compared to the same period last year. The ACLL to total loans ratio was 1.34% in the third quarter, down from 1.35% in the prior quarter and up from 1.33% in the same period last year.
In 2025, we continue to expect to adjust provision to reflect changes to risk grades, economic conditions, loan volumes, and other indications of credit quality.
Capital
The Company’s capital position remains strong, with a CET1 capital ratio of 10.33% at September 30, 2025. The Company’s capital ratios continue to be in excess of the Basel III “well-capitalized” regulatory benchmarks on a fully phased in basis.

Forward-looking statements are based on current management expectations and, by their nature, are subject to risks and uncertainties. Actual results may differ materially from those contained in the forward-looking statements. Factors which may cause actual results to differ materially from those contained in such forward-looking statements include those identified in the Company’s most recent Form 10-K and subsequent Form 10-Qs and other SEC filings, and such factors are incorporated herein by reference.

Presentation: Within the charts and tables presented, certain segments, columns and rows may not sum to totals shown due to rounding. Non-GAAP measures: This presentation includes certain non-GAAP financial measures. These financial measures have been included as they provide meaningful supplemental information to assess trends in the Corporation’s results of operations. These non- GAAP measures are provided in addition to, and not as substitutes for, measures of our financial performance determined in accordance with GAAP.
