**Westport Provides Bi-Weekly Management Cease Trade Order Status Update** 

VANCOUVER, British Columbia, April 15, 2026 (GLOBE NEWSWIRE) -- Westport Fuel Systems Inc. ("Westport" or the "Company") (TSX:WPRT / Nasdaq: WPRT) is providing this bi-weekly management cease trade order status report in accordance with National Policy 12-203 – *Management Cease Trade Orders* ("NP 12-203").

On April 1, 2026, the Company announced that, at the request of the Company, the British Columbia Securities Commission issued a temporary management cease trade order against the Company (the "MCTO") under NP 12-203 in connection with the Company's delayed filing of its: (i) audited consolidated financial statements for the fiscal year ended December 31, 2025 (the "Annual Financial Statements"), (ii) management's discussion and analysis relating to the Annual Financial Statements, (iii) CEO and CFO certificates relating to the Annual Financial Statements and (iv) annual information form on Form 20-F (collectively, (the "Annual Filings"), as a result of the cybersecurity incident previously announced by the Company on March 20, 2026 (the "Announcement"). Each of the Annual Filings was required to be filed by March 31, 2026, under Canadian securities laws. The MCTO restricts trading in the Company's securities by the CEO and CFO but does not restrict trading by other shareholders or investors.

Pursuant to NP 12-203, Westport must file bi-weekly default status reports by way of news releases during the period of the MCTO. The Company confirms that since the date of the announcement, the investigation of the cyber incident has concluded and included a review of internal controls over financial reporting. Management has concluded that the Company's internal controls over financial reporting were not deficient in connection with the incident. A revised scope of audit activity in relation to the Annual Filings has been defined and is now underway. Westport plans to issue its Annual Filings as soon as possible.

Westport confirms that since the date of the Announcement: (i) there has been no material change to the information set out in the Announcement that would reasonably be expected to be material to an investor; (ii) the Company is satisfying and intends to continue to satisfy the alternative information guidelines under NP 12-203 by providing bi-weekly status updates by way of news release until the Annual Filings are filed; (iii) the Company does not anticipate any subsequent specified defaults under NP 12-203; and (iv) there is no material information concerning the affairs of the Company that has not been generally disclosed
