SolarBank Renews Base Shelf Prospectus

Toronto, Ontario, May 8, 2025 — SolarBank Corporation (NASDAQ: SUUN; Cboe CA: SUNN, FSE: GY2) (“SolarBank” or the “Company”) announced today that it has filed a final short form base shelf prospectus (the “Shelf Prospectus“) with the securities regulatory authorities in each of the provinces of Canada. The Shelf Prospectus replaces the Company’s prior final short form base shelf prospectus dated May 2, 2023 which would have expired in June 2025.   A corresponding shelf registration statement on Form F-10 (the “Registration Statement”) has been filed with the United States Securities and Exchange Commission but is not yet effective.

The Shelf Prospectus will enable the Company to make offerings of up to C$200 million of common shares, debt securities, warrants, subscription receipts, units and share purchase contracts or a combination thereof of the Company from time to time, separately or together, in amounts, at prices and on terms to be determined based on market conditions at the time of the offering and as set out in an accompanying prospectus supplement, during the 25-month period that the Shelf Prospectus remains valid.

The nature, size and timing of any such financings (if any) will depend, in part, on the Company’s assessment of its requirements for funding and general market conditions. Unless otherwise specified in the prospectus supplement relating to a particular offering of securities, the net proceeds from any sale of any securities will be used for to advance the Company’s business objectives and for general corporate purposes, including funding ongoing operations or working capital requirements, repaying indebtedness outstanding from time to time, discretionary capital programs and potential future acquisitions. The specific terms of any future offering will be established in a prospectus supplement to the Shelf Prospectus, which supplement will be filed with the applicable Canadian securities regulatory authorities.

A copy of the Shelf Prospectus is available on SEDAR+ (www.sedarplus.ca) and also may be obtained by contacting the Chief Administrative Officer of the Company at 505 Consumers Road, Suite 803, Toronto, Ontario, M2J 4Z2, telephone (416) 494-9559 and a copy of the Registration Statement can be found on EDGAR at www.sec.gov.

No offer to buy any securities of the Company can be accepted until the Registration Statement has become effective.
