Westport Fuel Systems reported a decline in quarterly revenue to $1.6 million due to the divestiture of its light-duty business but demonstrated strategic growth through its Cespira unit, which saw a 19% revenue increase.

• Revenue decreased significantly from $4.9 million in Q3 2024 to $1.6 million in Q3 2025, primarily due to the conclusion of a transitional service agreement.
• Cespira generated $19.3 million in revenue, marking a 19% year-over-year increase, despite facing negative gross profit margins.
• Adjusted EBITDA worsened to negative $5.9 million, reflecting increased operating expenses and foreign exchange losses of $1.3 million.
• Cash and cash equivalents improved to $33.1 million, bolstered by proceeds from the light-duty business sale, enhancing liquidity post-divestiture.
• The company anticipates continued cost reductions as it transitions to a streamlined operational structure focusing on heavy-duty and alternative fuel segments.
