Our performance highlights this quarter include a continued strong net interest margin at 4.11% and deposit growth, complemented by our diversified business mix with noninterest income to total revenue at 21.9%. Our consistent focus on our C&I, consumer and service fee businesses has enabled us to deliver strong earnings again this year. Further, our strong performance was recognized earlier this month by Kroll Bond Rating Agency, LLC as they affirmed our debt ratings, as well as the debt and deposit ratings for our subsidiary, Sunflower Bank, N.A.

“Also, we have recently taken a few branching related actions as part of our recurring evaluation of all our markets. We are pleased to announce that late in the fourth quarter of 2024, our regulator approved our planned relocation of a branch located in Albuquerque, New Mexico. Additionally, earlier in January 2025, we submitted applications with our regulator to establish two new depository branches, one in each of our San Diego and Los Angeles, CA expansion markets. We expect to add to our investment in these large and diverse growth markets. Finally, I want to thank all of our hard working employees for their continued service to all of our customers and their commitment to excellence.”

1 Total revenue is net interest income plus noninterest income.

Net interest income totaled $77.0 million for the fourth quarter of 2024, an increase of $0.9 million compared to the prior quarter. Our net interest margin increased one basis point to 4.11% compared to the prior quarter. Results for the fourth quarter of 2024, compared to the prior quarter, were primarily driven by a decrease of 30 basis points in the cost of interest-bearing liabilities, largely offset by a decrease of 20 basis points in the yield on earning assets.

Average loans, including loans held-for-sale, increased by $21.2 million in the fourth quarter of 2024, compared to the prior quarter. Loan yield decreased by 16 basis points to 6.55% in the fourth quarter of 2024, compared to the prior quarter, primarily due to the declining interest rate environment and its impact on variable rate loans in the portfolio. Average interest-bearing deposits increased $35.8 million in the fourth quarter of 2024, compared to the prior quarter. Total cost of interest-bearing deposits decreased by 29 basis points to 2.87% in the fourth quarter of 2024, compared to the prior quarter, primarily due to a decrease in average certificates of deposit balances. Average FHLB borrowings decreased $13.7 million in the fourth quarter of 2024, compared to the prior quarter. The cost of FHLB borrowings decreased by 56 basis points to 5.05% in the fourth quarter of 2024, compared to the prior quarter.

The provision for credit losses totaled $4.9 million for the fourth quarter of 2024 primarily due to the combined impact of certain deteriorating factors influencing macroeconomic forecasts and deterioration on a specific customer relationship in our loan portfolio, partially offset by the release of a specific allowance for credit losses associated with the full pay-off of a previous nonperforming loan.

Net charge-offs (recoveries) for the fourth quarter of 2024 were $(0.5) million resulting in an annualized ratio of net charge-offs (recoveries) to average loans of (0.03)%, compared to net charge-offs of $1.4 million, or an annualized ratio of net-charge offs to average loans of 0.09% for the prior quarter.

The allowance for credit losses as a percentage of total loans was 1.38% at December 31, 2024, an increase of nine basis points from the prior quarter. The ratio of nonperforming assets to total assets was 0.92% at December 31, 2024, compared to 0.86% at September 30, 2024.

Noninterest income totaled $21.6 million for the fourth quarter of 2024, a decrease of $0.4 million from the prior quarter. Mortgage banking income increased $0.8 million for the fourth quarter of 2024, primarily due to an increase in net capitalized servicing values and a change in fair value of our MSR asset, net of hedging activity, partially offset by a decrease in revenue related to net sale gains and fees from mortgage loan originations, including fair value changes in the held-for-sale portfolio and hedging.

Other noninterest income decreased $1.1 million for the fourth quarter of 2024, primarily due to a decrease in the fair value of investments related to our deferred compensation plan. Noninterest income as a percentage of total revenue2 was 21.9%, a decrease of 0.5% from the prior quarter.

Noninterest expense totaled $73.7 million for the fourth quarter of 2024, an increase of $9.0 million from the prior quarter, primarily due to an increase in terminated merger related expenses of $6.4 million from the prior quarter. Additional non-recurring expenses in the fourth quarter of 2024 include $2.0 million of costs to dispose of a majority of our ATMs and amend our associated service contract as we move to participating in a national ATM network, and a $0.8 million write-off of the Guardian Mortgage trade name as we are in the process of rebranding our residential mortgage business as Sunflower Bank Mortgage Lending. Adjusted noninterest expense, a non-GAAP financial measure, totaled $62.8 million for the fourth quarter of 2024, a decrease of $0.2 million from the prior quarter.
