Cyber incident delays Westport (Nasdaq: WPRT) 2025 reports, triggers management trade ban
Rhea-AI Filing Summary
Westport Fuel Systems Inc. reports that the British Columbia Securities Commission has issued a temporary management cease trade order restricting trading in the company’s securities by its CEO and CFO after a previously disclosed cybersecurity incident delayed its 2025 year-end reporting. The company has missed the March 31, 2026 deadline for filing its audited financial statements, management’s discussion and analysis, CEO/CFO certifications, and annual information form for the year ended December 31, 2025. Westport is working with its auditors to assess the incident’s impact on financial reporting and internal controls and plans to complete any additional audit work, revise its annual documents if necessary, and file them as promptly as possible while providing bi-weekly status updates under National Policy 12-203.
Positive
- None.
Negative
- Delayed audited 2025 reporting and governance overhang: Westport missed the March 31, 2026 deadline for its 2025 audited financial statements and related annual filings after a cybersecurity incident, triggering a temporary management cease trade order that highlights financial reporting and internal control uncertainty.
Insights
Cyberattack-linked delays and a management trade ban raise governance and reporting risk.
Westport Fuel Systems is under a temporary management cease trade order because its 2025 audited financials and related annual filings were not submitted by the March 31, 2026 deadline after a cybersecurity incident.
The order only restricts the CEO and CFO from trading, leaving other investors unaffected, but it underscores uncertainty around financial reporting and potential deficiencies in internal controls over financial reporting being evaluated with auditors.
Until the company completes any additional audit work, finalizes possible revisions, and files its year-end documents, the lack of current audited information and ongoing cyber-related review represent a meaningful overhang for investors focused on transparency and governance.

Westport Announces Issuance of Management Cease Trade Order
VANCOUVER, British Columbia, April 01, 2026 (GLOBE NEWSWIRE) -- Westport Fuel Systems Inc. (“Westport" or the “Company”) (TSX:WPRT / Nasdaq: WPRT) today announced that the British Columbia Securities Commission, the Company’s principal regulator, has issued a temporary management cease trade order (the “MCTO“) against the Company under National Policy 12-203 – Management Cease Trade Orders (“NP 12-203“). The MCTO restricts trading in the Company’s securities by the CEO and CFO, but does not restrict trading by other shareholders or investors.
“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.”
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. Each of the Annual Filings were required to be filed by March 31, 2026 under Canadian securities laws.
In advance of filing the Company’s Annual Documents, Westport is working closely with its auditors to (i) assess and determine the scope of the cybersecurity incident with respect to the documents and data relevant to the Annual Documents; (ii) determine whether the Company's internal controls over financial reporting were deficient in connection with the incident; (iii) if so, determine whether such deficiency requires a change to the scope of the auditors' audit procedures in respect of the audited annual financial statements; and (iv) complete any additional required audit activity and any revisions to the Annual Documents, if required. Westport plans to file the required disclosure as promptly as possible.
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.
