AMES NATIONAL CORPORATION

ANNOUNCES EARNINGS FOR THE FIRSTQUARTER OF 2025

Ames, Iowa – Ames National Corporation (Nasdaq: ATLO; the “Company”) today reported net income for the first quarter of 2025 of $3.4 million, or $0.39 per share, compared to $2.3 million, or $0.26 per share, earned in the first quarter of 2024.  The increase in earnings is primarily due to an increase in net interest income and partially offset by an increase in credit loss expense. The increase in net interest income is primarily due to an increase in the volume and yield of loans and a decrease in interest expense on other borrowed funds as the Company has reduced borrowings. The increase in credit loss expense is primarily due to a specific reserve placed on a commercial loan relationship.

First Quarter 2025 Results:

First quarter 2025 loan interest income was $852 thousand higher than first quarter 2024 and was primarily due to higher interest rates and growth in the loan portfolio. Deposit interest expense decreased $170 thousand during this same period due primarily to a decrease in market rates. Other borrowed funds interest expense decreased $832 thousand during the same period due primarily to reduced borrowings. First quarter 2025 net interest income totaled $12.9 million, an increase of $2.0 million, or 18.4%, compared to the same quarter a year ago. These factors were the primary contributors to the Company’s net interest margin improving to 2.53% for the quarter ended March 31, 2025 as compared to 2.13% for the quarter ended March 31, 2024 and 2.38% for the quarter ended December 31, 2024.  

A credit loss expense of $962 thousand was recognized in the first quarter of 2025 as compared to $169 thousand in the first quarter of 2024. Net loan charge-offs for the quarter ended March 31, 2025 totaled $48 thousand compared to net loan recoveries of $4 thousand for the quarter ended March 31, 2024. The credit loss expense in 2025 was primarily due to an increase in specific reserves in the commercial loan portfolio. The credit loss expense in 2024 was primarily due to an increase in the risks associated with the softening of commercial real estate collateral values.

Noninterest income for the first quarter of 2025 totaled $2.55 million as compared to $2.18 million in the first quarter of 2024, an increase of 17.0%. The increase is primarily due to an increase in wealth management income and a decrease in losses on the sale of securities.

Noninterest expense for the first quarter of 2025 totaled $10.26 million compared to $10.19 million recorded in the first quarter of 2024, an increase of 0.7%. The efficiency ratio was 66.38% for the first quarter of 2025 as compared to 77.92% in the first quarter of 2024. The efficiency ratio continues to improve as net interest margin increases and noninterest expense is comparable to the prior year.

Income tax expense for the first quarter of 2025 totaled $794 thousand compared to $416 thousand recorded in the first quarter of 2024. The effective tax rate was 19% and 15% for the quarters ended March 31, 2025 and 2024, respectively. The lower than expected tax rate in 2025 and 2024 was primarily due to tax-exempt interest income and New Markets Tax Credits.

Balance Sheet Review:

As of March 31, 2025, total assets were $2.2 billion, a decrease of $7.5 million, as compared to March 31, 2024. The decrease in assets was primarily due to a decrease in securities available-for-sale, partially offset by an increase in interest-bearing deposits in financial institutions and loans.

Securities available-for-sale as of March 31, 2025 decreased to $640.4 million from $723.2 million as of March 31, 2024. The decrease in securities available-for-sale is primarily due to maturities in excess of purchases. The Company's investment portfolio had an expected duration of 3.0 years as of March 31, 2025. There are approximately $105 million of investments maturing within one year at an average yield of approximately 1.6%.

Net loans as of March 31, 2025 increased to $1.31 billion as compared to $1.27 billion as of March 31, 2024, an increase of 2.6%. The increase was primarily due to an increase in the agriculture and 1 to 4 family residential real estate loan portfolios. Substandard loans were $32.4 million and $24.2 million as of March 31, 2025 and 2024, respectively. Substandard-impaired loans were $15.7 million and $12.6 million as of March 31, 2025 and 2024, respectively. The increase in substandard and substandard-impaired loans is primarily due to weakening in the commercial real estate loan portfolio. Some commercial real estate loans are experiencing a decline in occupancy rates and collateral valuation. There are approximately $279 million of loans maturing within one year at an average yield of approximately 6.2%.

The allowance for credit losses on March 31, 2025 totaled $18.0 million or 1.36% of loans, compared to $17.0 million, or 1.31% of loans, as of March 31, 2024. The increase in the allowance for credit losses is mainly due to a specific reserve placed on a commercial loan relationship.

Deposits totaled $1.91 billion as of March 31, 2025, an increase of 1.8%, compared to $1.87 billion recorded as of March 31, 2024. The increase in deposits is primarily due to an increase in time deposits and public funds, partially offset by lower balances in retail and commercial noninterest-bearing checking accounts as customers seek higher interest rates. Securities sold under agreements to repurchase decreased to $45.8 million as of March 31, 2025, compared to $53.0 million as of March 31, 2024. Securities sold under agreements to repurchase and deposit balances fluctuate as customers’ liquidity needs vary and could be impacted by prevailing market interest rates, competition, and economic conditions.  Approximately 16% of deposits are tied to external indexes as of March 31, 2025. Deposit interest expense related to these deposits can be more volatile than other deposit products in a changing interest rate environment.

Other borrowings decreased to $35.8 million as of March 31, 2025 compared to $90.3 million as of March 31, 2024. The Company has continued to reduce borrowings as investments have matured.

The Company’s stockholders’ equity represented 8.4% of total assets as of March 31, 2025 with all of the Company’s six affiliate banks considered well-capitalized as defined by federal capital regulations. Total stockholders’ equity was $183.1 million as of March 31, 2025, compared to $165.5 million as of March 31, 2024. The increase in stockholders’ equity of $17.5 million was primarily the result of a decrease in unrealized losses on the investment portfolio and retention of net income in excess of dividends.

Share Repurchase Program

For the period January 1, 2025 through March 31, 2025, under the repurchase program that was announced in November 2024, which allowed for the repurchase of 100,000 shares of common stock, the Company repurchased 33,553 shares of its common stock at an average price of $16.41 per share and a total cost of $551 thousand.  There were 23,390 shares available to be repurchased under that repurchase program as of March 31, 2025.

Cash Dividend Announcement

On February 12, 2025, the Company declared a quarterly cash dividend on common stock, payable on June 13, 2025 to stockholders of record as of May 30, 2025, equal to $0.20 per share. The quarterly dividend will be paid a month later than usual. Previously, dividends were typically declared in one quarter and paid in the subsequent quarter. Going forward, the Company expects, subject to the discretion of the Board of Directors, to declare and pay dividends in the same quarter. To convert to this new timing, the Company does not intend to declare a dividend in the second quarter payable in the third quarter; rather, the dividend typically paid in the third quarter would be both declared and paid in the third quarter.
