CEO Comments

President and Chief Executive Officer Katie Lorenson said, “Alerus delivered another quarter of strong progress towards our goal of achieving sustained top tier performance. The results underscore the power of our diversified business model and disciplined execution. We reported net income of $20.3 million and adjusted earnings per diluted share of $0.72 for the second quarter of 2025, a 28.6% increase from the prior quarter. Our adjusted return on average tangible common equity expanded to 21.0%, and adjusted return on average assets improved to 1.41%, reflecting both revenue growth and disciplined expense management. We continued to optimize our balance sheet with the recent strategic sale of $62.5 million of non-owner occupied commercial real estate loans. These actions, combined with our adjusted net charge-offs to average loans of just 0.07%, demonstrate our proactive credit risk management and portfolio discipline. We maintained our long history of dividend increases in the second quarter while growing tangible book value per share by over 20.0% annualized compared to the prior quarter. These metrics demonstrate our commitment to delivering consistent shareholder value while maintaining a strong capital position and improving our balance sheet and risk profile. We remain focused on executing our long-term strategy, enhancing client relationships, and driving sustainable growth across our One Alerus integrated banking, wealth, and retirement services businesses.”

Results of Operations

Net Interest Income

Net interest income for the second quarter of 2025 was $43.0 million, a $1.9 million, or 4.6%, increase from the first quarter of 2025. The increase was primarily due to the repricing of maturing loans into loans with higher yields and purchase accounting accretion partially offset by higher interest expense as the impact of lower rates paid on interest-bearing deposits was more than offset by increased short-term borrowings balances.

Net interest income increased $19.0 million, or 79.3%, from $24.0 million for the second quarter of 2024. Interest income increased $17.4 million, or 32.8%, from the second quarter of 2024, primarily driven by earning assets acquired in the HMN Financial, Inc. (“HMNF”) transaction, strong organic loan growth at higher yields, and purchase accounting accretion. Interest expense decreased $1.6 million, or 5.6%, from the second quarter of 2024, as a decrease in the average rate paid on deposits more than offset the increase in interest-bearing deposits stemming from the acquisition of HMNF and organic deposit growth.

Net interest margin (on a tax-equivalent basis) (non-GAAP) was 3.51% for the second quarter of 2025, a 10 basis point increase from 3.41% for the first quarter of 2025, and a 112 basis point increase from 2.39% for the second quarter of 2024. The quarter over quarter increase was mainly attributable to higher loan rates on new loan originations against a stable cost of funds. The increase from the second quarter of 2024 was primarily driven by higher rates on interest earning assets from organic loan growth and the HMNF acquisition, purchase accounting accretion, and lower rates paid on deposits.

Noninterest Income

Noninterest income for the second quarter of 2025 was $31.8 million, a $4.1 million increase from the first quarter of 2025. The quarter over quarter increase was primarily driven by increases in mortgage banking and gain on sale of non-mortgage loans. Mortgage banking revenue increased $2.1 million, or 139.1%, from the first quarter of 2025, primarily driven by increased mortgage originations due to expected seasonality. Gain on sale of non-mortgage loans increased from the first quarter of 2025 due to a $2.1 million gain on the sale of a PCD hospitality loan during the second quarter of 2025.

Noninterest income for the second quarter of 2025 increased by $4.4 million from the second quarter of 2024. Gain on sale of non-mortgage loans increased in the second quarter of 2025 compared to the second quarter of 2024 due to a $2.1 million gain on the sale of a PCD hospitality loan during the second quarter of 2025. Wealth revenue increased $1.0 million, or 15.8%, in the second quarter of 2025 compared to the second quarter of 2024, primarily driven by a 10.6% increase in assets under administration/management during that same period as a result of improved bond and equity markets as well as the HMNF acquisition. Mortgage banking revenue increased $1.1 million, or 43.0%, in the second quarter of 2025 compared to the second quarter of 2024, primarily driven by a higher gain on sale rate and increased mortgage servicing revenue driven by the HMNF acquisition.

Noninterest Expense

Noninterest expense for the second quarter of 2025 was $48.4 million, a $1.9 million, or 3.8%, decrease from the first quarter of 2025. Employee taxes and benefits expense decreased $1.1 million, or 14.5%, from the first quarter of 2025, primarily due to seasonality. Professional fees and assessments decreased $0.7 million, or 21.9%, from the first quarter of 2025, primarily driven by decreases in acquisition-related expenses and Federal Deposit Insurance Corporation (“FDIC”) assessments. Other noninterest expense decreased $1.4 million, or 50.3%, from the first quarter of 2025, primarily driven by an insurance reimbursement. Compensation expense increased $1.4 million, or 6.0%, from the first quarter of 2025, partially driven by higher performance incentives, especially within the mortgage business.

Noninterest expense for the second quarter of 2025 increased $9.7 million, or 25.0%, from $38.8 million in the second quarter of 2024. The total increase was primarily driven by increases in compensation expense, employee taxes and benefits expense, intangible amortization expense, business services, software and technology expense, and occupancy and equipment expense. In the second quarter of 2025, compensation expense increased $4.1 million, or 20.1%, and employee taxes and benefits expense increased $1.5 million, or 29.2%. Both compensation expense and employee taxes and benefits expense increased compared to the second quarter of 2024 primarily due to increased headcount resulting from the HMNF acquisition. Intangible amortization expense increased $1.4 million in the second quarter of 2025, primarily driven by the $33.5 million core deposit intangible recorded in connection with the HMNF acquisition. Business services, software and technology expense increased $1.3 million, or 27.6%, from the second quarter of 2024, primarily driven by the increased company size due to the HMNF acquisition along with multiple platform upgrades. Occupancy and equipment expense increased $0.7 million, or 41.0%, from the second quarter of 2024, primarily driven by the increased branch footprint resulting from the HMNF acquisition.

Financial Condition

Total assets were $5.3 billion as of June 30, 2025, an increase of $62.1 million, or 1.2%, from December 31, 2024. The increase was primarily due to a $52.1 million increase in loans held for investment and a non-cash transfer of $50.2 million to non-mortgage loans held for sale, partially offset by a decrease of $46.9 million in available-for-sale investment securities and a decrease of $11.9 million in held-to-maturity investment securities.

Loans Held for Investment

Total loans held for investment were $4.0 billion as of June 30, 2025, an increase of $52.1 million, or 1.3%, from December 31, 2024. The increase was primarily driven by a $36.8 million increase in commercial loans and a $15.3 million increase in consumer loans. Non-owner occupied commercial real estate loans held for investment decreased $63.9 million, or 6.7%, from the first quarter of 2025, primarily driven by a transfer of $50.2 million to non-mortgage loans held for sale.

Deposits

Total deposits were $4.3 billion as of June 30, 2025, a decrease of $40.9 million, or 0.9%, from December 31, 2024. Interest-bearing deposits increased $72.2 million and noninterest-bearing deposits decreased $113.2 million from December 31, 2024. The decrease in total deposits was due primarily to seasonal outflows from public funds depositors, tax related outflows, as well as a return to more normalized levels of clearing and synergistic deposits. The decrease was partially offset by an increase in brokered deposit balances as callable brokered certificates of deposit were raised to diversify the funding structure while retaining optionality.

Non-GAAP Financial Measures

Some of the financial measures included in this press release are not measures of financial performance recognized by U.S. Generally Accepted Accounting Principles, or GAAP. These non-GAAP financial measures include the ratio of tangible common equity to tangible assets, tangible book value per common share, return on average tangible common equity, efficiency ratio, pre-provision net revenue, adjusted noninterest income, adjusted noninterest expense, adjusted pre-provision net revenue, adjusted efficiency ratio, adjusted net income, adjusted return on average total assets, adjusted return on average tangible common equity, net interest margin (tax-equivalent), adjusted earnings per common share - diluted, and adjusted net charge-offs to average loans. Management uses these non-GAAP financial measures in its analysis of its performance, and believes financial analysts and investors frequently use these measures, and other similar measures, to evaluate capital adequacy and financial performance. Reconciliations of non-GAAP disclosures used in this press release to the comparable GAAP measures are provided in the accompanying tables. Management, banking regulators, many financial analysts and other investors use these measures in conjunction with more traditional bank capital ratios to compare the capital adequacy of banking organizations with significant amounts of goodwill or other intangible assets, which typically stem from the use of the purchase accounting method of accounting for mergers and acquisitions.

These non-GAAP financial measures should not be considered in isolation or as a substitute for total stockholders’ equity, total assets, book value per share, return on average assets, return on average equity, or any other measure calculated in accordance with GAAP. Moreover, the manner in which the Company calculates these non-GAAP financial measures may differ from that of other companies reporting measures with similar names.
