FORM 6-K
Regulatory Filings Classification · 95% confidence The document is a Form 6-K, which is a report of a foreign private issuer pursuant to SEC rules. It includes a press release as Exhibit 99.1 but does not contain detailed financial statements or substantive financial data. The document length is 2553 characters, which is relatively short and primarily serves as a regulatory filing to furnish information to the SEC. It does not represent an annual report, interim report, earnings release, or other detailed financial or management report. Therefore, it fits best under the category of Regulatory Filings (RNS), which is the fallback for miscellaneous SEC filings that do not fit other categories.

6-K
Regulatory Filings Classification · 95% confidence The document is a Form 6-K filed with the SEC by a foreign private issuer, Westport Fuel Systems Inc., for the month of November 2025. It includes references to exhibits containing Management's Discussion and Analysis (MD&A) and Condensed Consolidated Financial Statements for the period ended September 30, 2025. However, the document itself is a report submission (Form 6-K) which typically serves as a regulatory filing to provide updates between annual reports. The document length is 2268 characters, which is relatively short and mainly serves as a cover/report submission with exhibits incorporated by reference. There is no full annual or interim report text here, only references to exhibits. According to the rules, such filings are classified as Regulatory Filings (RNS) because they do not contain the full financial report but are a regulatory update filing with attached exhibits.
