FOR IMMEDIATE RELEASE:
Wellsboro, PA – The Board of Directors of Citizens & Northern Corporation (C&N) (NASDAQ: CZNC), parent company of Citizens & Northern Bank, has approved a new treasury stock repurchase program.
Announcement of a new treasury stock repurchase program follows the recent completion of a common stock repurchase plan authorized by the Board of Directors in April 2016 and amended in February 2021. In total, 1,000,000 shares, or approximately 6.25% of the total shares outstanding on February 18, 2021, were repurchased under the previous program for a total cost of $23.086 million, at an average price of $23.09 per share.

Consistent with the previous program, the Board of Directors’ September 22, 2023 authorization provides that: (1) the new treasury stock repurchase program shall be effective when publicly announced and shall continue thereafter until suspended or terminated by the Board of Directors, in its sole discretion; and (2) all shares of common stock repurchased pursuant to the new program shall be held as treasury shares and be available for use and reissuance for purposes as and when determined by the Board of Directors including, without limitation, pursuant to C&N’s Dividend Reinvestment and Stock Purchase Plans and its equity compensation program.
