MINNEAPOLIS (December 14, 2023) – Alerus Financial Corporation (NASDAQ: ALRS) announced that its board of directors declared a regular quarterly cash dividend of $0.19 per common share, a 5.56% increase over the dividend paid a year ago. The dividend is payable on January 12, 2024, to shareholders of record as of close of business on December 27, 2023. Current and historic dividend information, as well as quarterly financial statements, investor presentations, and earnings call transcripts are available online through Alerus’ investor relations website at investors.alerus.com.

The Company also announced that its board of directors approved a new stock repurchase program (the “New Stock Repurchase Program”) which authorizes the Company to repurchase up to 1,000,000 shares of its common stock, subject to certain limitations and conditions. The New Stock Repurchase Program will become effective on February 18, 2024, and will expire on February 18, 2027. On February 18, 2024, the New Stock Repurchase Program will replace and supersede the Company’s existing stock repurchase program which was originally announced on February 22, 2021.
