MADISON, Wis.--(BUSINESS WIRE)--Jan. 29, 2026-- First Business Financial Services, Inc. (the “Company”, the “Bank”, or “First Business Bank”) (Nasdaq: FBIZ) reported quarterly net income available to common shareholders of $13.1 million, or earnings per share ("EPS") of $1.58. This compares to net income available to common shareholders of $14.2 million, or $1.70 per share, in the third quarter of 2025 and $14.2 million, or $1.71 per share, in the fourth quarter of 2024.

“First Business Bank continued to produce strong deposit and loan growth that outpaced the industry, expanding client relationships and driving outstanding financial performance during the fourth quarter,” said Corey Chambas, Chief Executive Officer. “We concluded 2025 with positive momentum. Our revenue growth goals continued to be supported by robust loan pipelines, expansion of our private wealth platform, core deposit growth, and diversified fee income sources. While we saw an increase in nonperforming loans due to a single client relationship, we continue to experience stable credit quality across our performing portfolio. We are pleased to report strong profitability despite this isolated event. We are on track with our five-year strategic plan, achieving 10% growth in top-line revenue and maintaining an efficiency ratio below 60%. This momentum continued to drive above-target performance on return on average tangible common equity and growth in tangible book value for 2025."

“We continued our track record of producing double-digit annual growth, exceeding 14% growth in both pre-tax, pre-provision adjusted earnings and earnings per share in 2025," Chambas continued. "We are particularly proud that we have sustained 10% compound average annual growth in earnings per share for the past 20 years. This consistent growth in earnings has supported our ability to provide shareholders a strong cash dividend that has grown for 14 consecutive years. We continue to target double-digit growth going forward."

Quarterly Highlights

• Robust Core Deposit Growth. Core deposits grew $80.9 million, or 12.5% annualized, from the linked quarter and $276.6 million, or 11.5%, from the fourth quarter of 2024. Core deposit funding mix improved to 74.7% compared to 71.5% in the linked quarter and 70.7% in the fourth quarter of 2024.

• Continued Loan Growth. Loans increased $38.6 million, or 4.6% annualized, from the third quarter of 2025, and $261.4 million, or 8.4%, from the fourth quarter of 2024. Loan growth was muted by elevated commercial real estate payoffs in the second half of 2025.

• Net Interest Margin. The Company's net interest margin of 3.53% included a 10 basis point impact of non-accrual interest reversals during the quarter. Net interest margin was 3.63% excluding this item, reflecting the Bank's effective match-funding strategy and pricing discipline. This compared to 3.68% for the linked quarter and 3.77% for the prior-year quarter.

• Commitment to Efficiency. The Company’s efficiency ratio improved to 56.61% from 57.44% and 56.94% in the linked and prior-year quarters, respectively. Efficiency ratio for the full year was 58.78% compared to 60.61%, producing positive operating leverage for the fourth consecutive year. We expect our disciplined expense management and balanced revenue growth to support positive operating leverage going forward.

• Continued Tangible Book Value Growth. The Company’s strong earnings and sound balance sheet management continued to drive growth in tangible book value per share, producing a 15.9% annualized increase compared to the linked quarter and a 13.7% increase compared to the prior-year quarter.
• Dividend Increase. The Company's quarterly cash dividend was increased 17%, to $0.34 per share, marking the Company's 14th consecutive annual increase.

Quarterly Financial Results

Fourth Quarter 2025 Compared to Third Quarter 2025

Net interest income decreased $124,000, or 0.4%, to $34.8 million.

• The decrease in net interest income was driven by non-accrual interest reversals in the current quarter and non-accrual interest recoveries in the linked quarter, partially offset by higher average loans and leases receivable. Average loans and leases receivable grew by $67.9 million, or 8.2% annualized, to $3.364 billion. Excluding non-accrual interest activity in both periods, net interest income increased $1.1 million, or 3.1%.
• The yield on average interest-earning assets decreased 34 basis points to 6.38% from 6.72% mainly due to non-accrual interest reversals in the current quarter and non-accrual interest recoveries in the linked quarter and reduction in short-term market rates. Excluding non-accrual interest activity in both periods, the yield on average interest-earning assets was 6.47% compared to 6.69% in the linked quarter. Excluding non-accrual interest activity in both periods, the interest- earning asset beta was 54.1%. The change in yield of the respective interest-earning asset or the rate paid on interest-bearing liability compared to the change in the effective daily fed funds rate is commonly referred to as beta.
• The rate paid for average core deposits decreased 25 basis points to 2.64% from 2.89%. The rate paid for average total bank funding decreased 19 basis points to 2.95% from 3.14%. Total bank funding is defined as total deposits plus Federal Home Loan Bank (“FHLB”) advances. The core deposit beta and total bank funding beta compared to the prior quarter was 62.5% and 47.5%, respectively.
• Net interest margin was 3.53% compared to 3.68% for the linked quarter. The decrease in net interest margin was driven primarily by non-accrual interest reversals in the current quarter and non-accrual interest recoveries in the linked quarter. Excluding non-accrual interest activity in both periods, net interest margin was 3.63% compared to 3.64% in the linked quarter.
• The Company maintains a long-term target for net interest margin in the range of 3.60% - 3.65%. Performance in future quarters will vary due to factors such as the level of fees in lieu of interest and the timing, pace, and scale of future interest rate changes.

The Bank reported provision for credit losses of $1.9 million compared to $1.4 million in the linked quarter. The current quarter provision primarily reflects net charge-offs and loan growth, partially offset by improvement in the economic outlook in our model forecast and a decrease in general reserve qualitative factors. Specific reserves were flat reflecting a decrease in reserve requirements in equipment finance lending offset by an increase in reserves in accounts receivable financing.

Non-interest income decreased $2.2 million, or 22.6%, to $7.5 million.

• Gain on sale of SBA loans decreased $242,000, or 63.4%, to $140,000, mainly due to delays related to the government shutdown.

• Commercial loan swap fee income decreased $236,000, or 24.2%, to $738,000. Swap fee income varies from period to period based on loan activity and the interest rate environment.

• Other non-interest income decreased $1.5 million, or 76.9%, to $458,000 mainly due to a reclassification of partnership investment expenses and $537,000 of nonrecurring fee income in accounts receivable financing in the prior quarter. In the fourth quarter, the Company reclassified $904,000 of investment expenses incurred during the first nine months of 2025 to net against the related revenue to present the net benefit of our partnership investments. The Company will continue this method of disclosure on a go-forward basis and prior-year periods were not adjusted due to immateriality.

• Bank-owned life insurance income decreased $226,000, or 23.4%, to $739,000 primarily due to a $234,000 insurance claim received in the prior quarter.

Non-interest expense decreased $1.6 million, or 6.1%, to $24.1 million, while operating expense decreased $1.5 million, or 6.0%, to $23.9 million.

• Compensation expense was $17.2 million, decreasing $291,000, or 1.7%, primarily due to a decrease in annual cash bonus and 401(k) accruals, partially offset by an increase in individual incentive compensation. Average full-time equivalents (“FTEs”) for the fourth quarter of 2025 were 368, up from 366 in the linked quarter.
• Other non-interest expense decreased $1.5 million, or 86.6%, to $225,000, primarily due to the aforementioned reclassification of partnership investment expenses and a decrease in donations and contributions.

Income tax expense decreased $88,000 to $2.9 million. The effective tax rate was 17.9% for the three months ended December 31, 2025, compared to 17.2% for the linked quarter. The change in tax expense reflects a decrease in pre-tax income and updated tax credit partnership estimates. The effective tax rate for the year ended December 31, 2025 was 16.8%. The Company expects to report an effective tax rate between 16% and 18% for 2026.

Total period-end loans and leases receivable increased $38.6 million, or 4.6% annualized, to $3.375 billion. Loan growth was muted due to elevated commercial real estate loan payoffs in the second half of 2025. The average rate earned on average loans and leases receivable was 6.77%, down 33 basis points from 7.10% in the prior quarter. Excluding the non-accrual interest reversals and recoveries, the average rate earned on average loans and leases receivable was 6.87% compared to 7.06% in the linked quarter.

Total period-end core deposits increased $80.9 million, or 12.5% annualized, to $2.673 billion. The average rate paid was 2.64%, down 25 basis points from 2.89% in the prior quarter primarily due to a decrease in short-term market rates.

Period-end wholesale funding, including FHLB advances and brokered deposits, decreased $48.2 million, or 5.1%, to $904.7 million due to an increase in core deposits. Consistent with the Bank’s long-held philosophy to minimize exposure to interest rate risk, management will continue to utilize the most efficient and cost-effective source of wholesale funds to match-fund fixed-rate loans, as necessary.

• Wholesale deposits decreased $33.5 million to $707.4 million. The average rate paid on wholesale deposits increased one basis point to 4.04% and the weighted average original maturity increased to 4.4 years from 4.3 years.

• FHLB advances decreased $14.7 million to $197.2 million. The average rate paid on FHLB advances decreased two basis points to 3.18% and the weighted average original maturity increased to 5.7 years from 5.3 years.

Non-performing assets increased $20.3 million to $43.9 million, or 1.07% of total assets, compared to 0.58% in the prior quarter. The increase primarily reflects the downgrade of $20.4 million of CRE loans from a single southeast Wisconsin-based client relationship. Management has evaluated the Bank's collateral position of these loans and concluded no specific reserves are required. This increase in non-performing assets was partially offset by lower non-accrual equipment finance loans.

The allowance for credit losses, including the unfunded credit commitments reserve, decreased $690,000, or 1.8%, primarily due to decreases in general reserves due to an improvement in the economic outlook in our model forecast, improvement in qualitative factors, and a decrease in specific reserves, partially offset by loan growth, general reserve model updates, and an increase in unfunded commitment reserves. The allowance for credit losses, including unfunded credit commitment reserves, as a percent of total gross loans and leases was 1.12% compared to 1.15% in the prior quarter.

Fourth Quarter 2025 Compared to Fourth Quarter 2024

Net interest income increased $1.6 million, or 4.9%, to $34.8 million.

• Growth reflects higher average gross loans and leases partially offset by the aforementioned non-accrual interest activity and lower prepayment fees. Excluding the non-accrual interest activity, net interest income increased $2.4 million, or 7.3%.
• The yield on average interest-earning assets decreased 46 basis points to 6.38% from 6.84%. Excluding the non-accrual interest activity, the yield on average interest-earning assets measured 6.47%. This decrease in yield was primarily due to the decrease in short-term market rates and lower prepayment fees, partially offset by the reinvestment of cash flows from the securities and fixed-rate loan portfolios. Excluding the non-accrual interest activity, the interest-earning asset beta was 46.7%
• The rate paid for average interest-bearing core deposits decreased 51 basis points to 3.14% from 3.65%. The rate paid for average total bank funding decreased 23 basis points to 2.95% from 3.18%. The core deposit and total bank funding betas compared to the prior year were 45.3% and 30.7%, respectively.
• Net interest margin decreased 24 basis points to 3.53% from 3.77%. Excluding the non-accrual interest activity, net interest margin was 3.63%. The remaining decrease in net interest margin was mainly due to a reduction in prepayment fees and the decrease in earning asset yields outpacing the decrease in total bank funding costs.

The Company reported provision for credit losses of $1.9 million, compared to $2.7 million in the fourth quarter of 2024. See the Provision for Credit Loss breakdown table below for more detail.

Non-interest income decreased $544,000, or 6.8%, to $7.5 million.
