Westport Files Preliminary Short Form Base Shelf Prospectus To Replace Expired Base Shelf Prospectus

VANCOUVER, British Columbia, Aug. 15, 2025 (GLOBE NEWSWIRE) -- Westport Fuel Systems Inc. ("Westport") (TSX: WPRT / Nasdaq: WPRT) announces it has filed a preliminary short form base shelf prospectus (once filed in final form and received by the relevant Canadian securities regulatory authorities, the “Shelf Prospectus”) with the securities commissions in each of the provinces and territories of Canada, to replace its prior base shelf prospectus that expired on June 18, 2025.

The Shelf Prospectus, when made final, will allow Westport to offer up to USD$100,000,000 of common shares, preferred shares, subscription receipts, warrants, debt securities, or units, or any combination thereof (collectively, the "Securities") during the 25-month period that the Shelf Prospectus will be effective. The Shelf Prospectus will enable Westport to access new capital or issue securities in connection with strategic acquisitions if and when needed. The amount and timing of any future offerings or issuances will be based on the Company’s financial requirements and market conditions at that time.

Westport has also filed a corresponding shelf registration statement relating to the Securities with the United States Securities and Exchange Commission ("SEC") on Form F-3 (the "Registration Statement").

The specific terms of any future offering or issuance under the Shelf Prospectus and Registration Statement will be established at the time of such offering. There are currently no offerings or issuances planned under these filings. At the time any of the Securities covered by these filings are offered for sale, a prospectus supplement containing specific information about the terms of such offering will be filed with applicable Canadian securities regulatory authorities and the SEC.

The Registration Statement has been filed with the SEC but has not yet become effective. The Securities may not be sold, nor may offers to buy be accepted, prior to the issuance of a receipt for the final Shelf Prospectus and the time the Registration Statement becomes effective. This news release shall not constitute an offer to sell or a solicitation of an offer to buy, nor shall there be any sale of these securities in any jurisdiction in which an offer, solicitation or sale would be unlawful prior to registration or qualifications under the securities laws of any such jurisdiction.

A copy of the preliminary short form base shelf prospectus can be found on SEDAR+ at www.sedarplus.ca and a copy of the corresponding shelf registration statement is available on EDGAR at www.sec.gov.
