independent registered public accounting firm regulatory
"KPMG had declined to stand for reappointment as Westport's independent registered public accounting firm"
An independent registered public accounting firm is an outside accounting company officially registered with the government regulator to examine and report on a public company's financial records and controls. Investors treat its reports like an impartial inspector’s certificate — they add credibility to financial statements, help spot errors or misleading claims, and reduce the risk that shareholders are relying on unchecked or biased numbers.
reportable event regulatory
"there was no reportable event requiring disclosure pursuant to Item 16F(a)(1)(v)"
Item 16F(a)(1)(v) regulatory
"no reportable event requiring disclosure pursuant to Item 16F(a)(1)(v) of the instructions to Form 20-F"
Form 20-F regulatory
"requiring disclosure pursuant to Item 16F(a)(1)(v) of the instructions to Form 20-F"
Form 20-F is the standardized annual disclosure that non-U.S. companies must file with the U.S. securities regulator when their shares are traded in the U.S.; it contains audited financial statements, a plain-language description of the business, management discussion, governance details and key risk factors. It matters to investors because it provides a consistent, comparable company “report card” and rulebook, helping buyers assess financial health, governance and risks before investing.
disagreements regulatory
"there were no “disagreements” between the Company and KPMG on accounting or audit matters"

INCORPORATION BY REFERENCE
This current report on Form 6-K, including the exhibits hereto, is hereby incorporated by reference into the Company's Registration Statement on Form F-3 (File No.333-289669) and the Registration Statements on Form S-8 (Registration Nos.333-248912, 333-211726 and 333-168847).
Change in Registrant’s Certifying Accountant
On May 7, 2026, KPMG LLP (“KPMG”) informed Westport Fuel Systems Inc. (“Westport”) that it had declined to stand for reappointment as Westport's independent registered public accounting firm (the "Resignation"). On May 8, 2026, subject to approval by Westport's shareholders at the next annual meeting of shareholders (the "Meeting") and effective as of the date of the Meeting, the Company appointed Deloitte LLP (“Deloitte”) to fill the vacancy, and to hold such position from the date of the Meeting until the close of the next annual meeting of shareholders of Westport. The Resignation and the appointment of Deloitte as auditor of the Company were considered and approved by the Audit Committee and the Board of Directors of Westport effective May 8, 2026. On June 30, 2026, at Westport's Meeting, Westport shareholders approved the appointment of Deloitte for the 2026 fiscal year. The reports of KPMG on the Company’s consolidated financial statements for either of the past two fiscal years did not contain any adverse opinion or disclaimer of opinion, and were not qualified or modified as to uncertainty, audit scope or accounting principles.
During the fiscal years ended December 31, 2025 and 2024, and through the date of KPMG’s Resignation, there were (i) no “disagreements” between the Company and KPMG on any matter of accounting principles or practices, financial statement disclosure, or auditing scope or procedure, which, if not resolved to the satisfaction of KPMG would have caused KPMG to make reference to the subject matter of the disagreement in connection with its reports on the Company’s consolidated financial statements for such years and (ii) there was no reportable event requiring disclosure pursuant to Item 16F(a)(1)(v) of the instructions to Form 20-F.
During the two most recent fiscal years and any subsequent interim period prior to the engagement of Deloitte, neither we nor anyone on behalf of us has consulted with Deloitte regarding (i) the application of accounting principles to a specific transaction, either completed or proposed, or the type of audit opinion that might be rendered on our consolidated financial statements, and neither a written report nor oral advice was provided to us that Deloitte concluded was an important factor considered by us in reaching a decision as to any accounting, auditing, or financial reporting issue, (ii) any matter that was the subject of a disagreement pursuant to Item 16F(a)(1)(iv) of the instructions to Form 20-F, or (iii) any reportable event pursuant to Item 16F(a)(1)(v) of the instructions to Form 20-F.
We provided a copy of the disclosures in this current report on Form 6-K to KPMG, requesting that KPMG furnish us with a letter addressed to the SEC stating whether it agrees with the above statements or, if not, stating the respects in which it does not agree. A copy of the letter has been filed as Exhibit 16.1 hereof.
