Record Quarterly Net Interest Income Drives Associated Banc-Corp's Second Quarter 2025 Earnings per Common Share of $0.65

GREEN BAY, Wis. -- July 24, 2025 -- Associated Banc-Corp (NYSE: ASB) ("Associated" or "Company") today reported net income available to common equity ("earnings") of $108 million, or $0.65 per common share, for the quarter ended June 30, 2025. These amounts compare to earnings of $99 million, or $0.59 per common share, for the quarter ended March 31, 2025 and earnings of $113 million, or $0.74 per common share, for the quarter ended June 30, 2024.

“Midway through 2025, Associated Bank is seeing strong momentum from the strategic actions we’ve taken over the past several quarters,” said President & CEO Andy Harmening. “In the second quarter, we delivered over $350 million in additional C&I loan growth, another 7 basis points of margin expansion, and the best checking household growth we’ve seen since we began tracking a decade ago--all of which contributed to the strongest quarterly net interest income we've seen in company history. Importantly, we also delivered another 9 basis points of CET1 capital accretion and solid credit performance.”

“While uncertainty has been an ongoing theme at the macro level, we feel well-positioned to build on our momentum over the back half of the year thanks to our strengthened profitability profile, solid capital position, and disciplined approach to growth. We look forward to providing additional updates on our progress along the way."

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 now expect total net interest income growth of 14% to 15% in 2025.

Noninterest Income

Second quarter 2025 total noninterest income of $67 million increased $8 million from the prior quarter and increased $2 million from the same period last year. The increase relative to the prior quarter was primarily driven by a $7 million loss recognized in the first quarter of 2025 related to the settlement of the mortgage sale originally announced in December of 2024. With respect to second quarter 2025 noninterest income line items:

•Capital markets, net increased $1 million from the prior quarter and $1 million from the same period a year ago.

•Card-based fees increased $1 million from the prior quarter and decreased $1 million from the same period last year.

•Wealth management fees increased $1 million from the prior quarter and increased slightly from the same period last year.

After adjusting to exclude the fourth quarter 2024 and first quarter 2025 impacts of the mortgage and investment securities sales we announced in December 2024, we now expect total noninterest income growth of between 1% and 2% in 2025.

Noninterest Expense

Second quarter 2025 total noninterest expense of $209 million decreased $1 million from the prior quarter and increased $13 million from the same period last year. With respect to second quarter 2025 noninterest expense line items:

•Personnel expense increased $3 million from the prior quarter and increased $5 million from the same period last year.

•Business development and advertising expense increased $1 million from the prior quarter and increased slightly from the same period last year.

•Legal and professional expense increased $1 million from the prior quarter and increased $2 million from the same period last year.

•Occupancy expense decreased $3 million from the prior quarter and decreased slightly from the same period last year.

•FDIC assessment expense decreased $1 million from the prior quarter and increased $3 million from the same period last year.

After adjusting to exclude the $14 million impact of the loss on prepayments of FHLB advances recognized in the fourth quarter of 2024, we now expect total noninterest expense to grow by 4% to 5% in 2025.

Taxes

Second quarter 2025 tax expense was $28 million, compared to $19 million of tax expense in the prior quarter and $13 million of tax benefit in the same period last year. The effective tax rate for the second quarter of 2025 was 20.34%, compared to 16.03% in the prior quarter.

We continue to expect the annual effective tax rate to be between 19% and 21% in 2025.

Credit

Second quarter 2025 provision for credit losses on loans was $18 million, compared to a provision of $13 million in the prior quarter and a provision of $23 million in the same period last year. With respect to second quarter 2025 credit quality:

•Nonaccrual loans of $113 million decreased $22 million from the prior quarter and decreased $41 million from the same period last year. The nonaccrual loans to total loans ratio was 0.37% in the first quarter, down from 0.44% in the prior quarter and down from 0.52% in the same period last year.

•Second quarter 2025 net charge offs of $13 million increased compared to net charge offs of $9 million in the prior quarter and decreased compared to net charge offs of $21 million in the same period last year.

•The allowance for credit losses on loans (ACLL) of $412 million increased $5 million compared to the prior quarter and increased $22 million compared to the same period last year. The ACLL to total loans ratio was 1.35% in the first quarter, up from 1.34% in the prior quarter and up from 1.32% 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 10.20%at June 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.

(c)Adjusted net income and adjusted net income available to common equity, which are used in the calculation of return on average tangible assets and return on average tangible common equity, respectively, add back other intangible amortization, net of tax.

(d)The Corporation is not classified as an advanced approaches holding company as defined by the Federal Reserve. As such, the Corporation has elected to be subject to the AOCI-related adjustments when calculating common equity tier 1 capital which allows the Corporation to opt-out of the requirement to include most components of AOCI in common equity tier 1 capital. This adjustment reflects that election.

We have not provided a reconciliation of the projection for core customer deposits to the projection for total deposits due to the low visibility and unpredictability of the components of total deposits necessary for such reconciliation. 3 Adjusted 2024 figures have been provided for noninterest income and noninterest expense to exclude the impact of nonrecurring items incurred as a result of a balance sheet repositioning that the Corporation announced in the fourth quarter of 2024.
