Westport Enters Into Committed Equity Facility of up to US$25 Million

VANCOUVER, British Columbia, Sept. 16, 2026 (GLOBE NEWSWIRE) -- Westport Fuel Systems Inc. (“Westport” or the “Company”) (TSX:WPRT / Nasdaq: WPRT), today announced that on September 15, 2026, it entered into a Committed Equity Facility (“CEF”) with Roth Principal Investments, LLC (“RPI”), an affiliate of CR Financial Holdings, Inc., the holding company for Roth Capital Partners.

The CEF allows, but does not obligate, Westport to issue and sell up to US$25 million of its common shares to RPI, at Westport’s discretion by way of private placement and subject to certain conditions set forth in the CEF agreement, following the filing and effectiveness of a registration statement registering the resale of such shares. Subject to certain specified exceptions, under the applicable Nasdaq rules, the Company may not issue to RPI under the CEF a number of common shares which is in excess of 19.99% of the common shares outstanding immediately prior to the execution of the CEF (the “Exchange Cap”), unless the Company obtains shareholder approval to issue Common Shares in excess of such Exchange Cap.

Westport intends to use any net proceeds for working capital and general corporate purposes. Westport may access capital opportunistically over time and is under no obligation to utilize the full amount available under the CEF. The Company may not be able to sell the full US$25 million of shares available under the facility due to limitations, including the Exchange Cap, the number of shares registered under an effective resale registration statement and applicable Nasdaq rules.

The Company intends to file a registration statement with the SEC to register the resale by RPI of the shares issuable under the CEF. These securities may not be resold until that registration statement is filed and becomes effective.

This press release does not constitute an offer to sell or the solicitation of an offer to buy, nor will there be any sales of these securities in any jurisdiction in which such offer, solicitation or sale would be unlawful prior to registration or qualification under the securities laws of such jurisdiction. The Company intends to rely on the eligible interlisted issuer exemption in section 602.1 of the TSX Company Manual in respect of the CEF.
