DEREGISTRATION OF SECURITIES

Citizens Community Bancorp, Inc. (the “Registrant”) is filing this post-effective amendment (the “Post-Effective Amendment”) to its Registration Statement on Form S-8 (Registration Statement No. 333-224042) (the “Registration Statement”), which has been previously filed with the Securities and Exchange Commission (the “SEC”), to deregister any and all shares of the Registrant’s common stock, par value $0.01 per share, registered but unsold or otherwise unissued under the Registration Statement as of the date hereof.

The Registration Statement, filed with the SEC on March 30, 2018, registered 350,000 shares for issuance under the Citizens Community Bancorp, Inc. 2018 Equity Incentive Plan (the “2018 Plan”).

On June 16, 2026, the Registrant’s stockholders approved the Citizens Community Bancorp, Inc. 2026 Omnibus Incentive Plan (the “2026 Plan”). The Registrant determined that, subject to stockholder approval of the 2026 Plan, the only shares available for future grants will be those reserved for issuance thereunder, as any shares available for future grant under the 2018 Plan would be cancelled upon approval of the 2026 Plan.

As a result of the foregoing, the offering contemplated by the Registration Statement has been terminated. In accordance with the undertakings contained in the Registration Statement to remove from registration, by means of a post-effective amendment, any and all securities registered but unsold at the termination of such offering, the Registrant hereby removes from registration any and all securities registered but unsold under the Registration Statement upon the effectiveness of this Post-Effective Amendment. The Registration Statement is hereby amended, as appropriate, to reflect the deregistration of such securities.
