The effectiveness unlocks the resale of 4.85M shares by CVI Investments. Given the company's going-concern warning and small market cap, this creates a clear overhang. Traders should watch for a Form 4 or Schedule 13D amendment signaling CVI's intent to sell. Any large block trade or volume spike could pressure the stock further.

Executive Summary
The SEC declared effective Westport Fuel Systems' F-1 registration statement (File No. 333-297598) on August 26, 2026. This allows the resale of 4,854,369 common shares by CVI Investments Inc., an institutional investor that acquired warrants in a June 2026 private placement. The effectiveness does not represent a new capital raise for the company, but it clears the path for potential near-term selling by the investor, adding overhang to a stock with a $35M market cap and a going-concern disclosure.
Key Facts
- Effectiveness date: August 26, 2026.
- Registration covers 4,854,369 common shares for resale by CVI Investments Inc.
