The MCTO restricts trading in the Company's securities by the CEO and CFO, but does not restrict trading by other shareholders or investors.</p>  <p align="justify">"On March 20, 2026, we announced that we had recently identified unauthorized access to certain internal systems and acted immediately to contain the incident, engaging cybersecurity experts and strengthening our safeguards," said Dan Sceli, Chief Executive Officer of Westport. "Importantly, our core operations remain unaffected, with no disruption to manufacturing or customer delivery. As we complete a thorough review to ensure the integrity of our financial reporting, we remain focused on transparency. Notwithstanding this incident, we continue to execute on our strategic priorities and build on the progress achieved over the past year."</p>  <p align="justify">The Company voluntarily applied for the MCTO 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, (together, the "Annual Filings"), as a result of the cybersecurity incident previously announced by the Company on March 20, 2026.

Westport plans to file the required disclosure as promptly as possible.</p>  <p align="justify">Westport will follow the alternative information guidelines under NP 12-203, and will provide bi-weekly status updates regarding the delayed filings by way of news release until the Annual Filings are filed.</p>  <p><strong>About Westport </strong></p>  <p align="justify">Westport is a technology and innovation company connecting synergistic technologies to power a cleaner tomorrow.
