Alerus Financial Corporation Reinvests $360M of Securities to Improve Profitability Profile

MINNEAPOLIS--(BUSINESS WIRE)--On December 23, 2025, Alerus Financial Corporation (Nasdaq: ALRS), or the Company, sold $360 million of available-for-sale (“AFS”) securities which represented over 68% of total AFS securities. The securities sold had a weighted average yield of 1.7% and a weighted average duration of 5.1 years. The sale resulted in a one-time pre-tax net loss of $68.5 million.

The Company reinvested the cash proceeds from the securities sale into new investment securities with a weighted average yield of 4.7% and a weighted average duration of just over 3 years. The Company now expects the 2026 net interest margin to be 3.50% to 3.60% versus the previous guidance of 3.35% to 3.45% provided in the Company’s 3^rd quarter earnings presentation. Risk based capital measures are expected to be above regulatory limits and internal targets at the end of 2025. The securities portfolio restructuring has no impact on tangible capital and positions the Company for higher earnings and improved financial returns in 2026 and beyond.

President and Chief Executive Officer Katie Lorenson commented, “Our focus in 2025 was to lower risk and improve returns without compromising our long-term strategy. In the back half of the year, we executed a purposeful deleveraging plan – actively managing loan paydowns and pruning marginal credits – to strengthen our balance sheet and improve our flexibility. As capital accreted and interest rate dynamics improved, we took disciplined action with our available-for-sale portfolio to better align assets with our organic growth expectations. We evaluated but did not pursue a full balance sheet restructuring as that would have required a dilutive common equity issuance. The deliberate steps we took positions Alerus for stronger performance and tangible book value growth in 2026 and demonstrates our commitment to creating long-term sustainable value for our clients, communities, and shareholders.”
