Westport Fuel Systems Reports Third Quarter 2017 Financial Results
Order Fulfillment of Westport™ HPDI 2.0 + Strengthened Balance Sheet

VANCOUVER, BC - Westport Fuel Systems Inc. (“Westport Fuel Systems”) (TSX:WPRT / Nasdaq:WPRT) reported financial results for the third quarter ended September 30, 2017, and provided an update on operations. All figures are in U.S. dollars unless otherwise stated.

"We continue to execute on our plan to strengthen our balance sheet, drive operational efficiencies, and advance the commercialization of Westport HPDI 2.0," said Nancy Gougarty, Chief Executive Officer of Westport Fuel Systems. "This is the first comparable quarter on a year-over-year basis since the merger and we see improved results across the board. The actions taken and implemented a year ago to achieve merger synergies are being realized. Q3 was a strong quarter with a 54% improvement in adjusted EBITDA compared to Q3 2016. Our Automotive business is delivering improved adjusted EBITDA; Cummins Westport is seeing strong customer demand and delivering higher income contributions; and our technology portfolio is market ready with products that deliver solutions to customers today. We have made significant progress and will remain focused on delivering our commitment towards becoming a profitable and sustainable company."

Q3 2017 Consolidated Financial Highlights

• Consolidated revenues for the quarter ended September 30, 2017, were $60.8 million compared with $56.1 million for the same period last year.  The higher revenues were driven by the increase in the Euro compared to the US dollar, as well as strong sales in the aftermarket business.
• Consolidated gross margin for the quarter ended September 30, 2017, was $14.8 million or 24% of revenue, compared with $8.7 million or 15% of revenue for the same period last year.  The improvement in gross margin is primarily due to higher revenues and operating efficiencies generated through post-merger synergies, particularly related to direct material savings and manufacturing footprint optimization.
• Consolidated operating expenses were $34.9 million for the quarter ended September 30, 2017, a decrease of 15% from $41.0 million in the same period last year.  The reduction in operating expenses is primarily related to the reduction in research and development programs as a result of portfolio optimization, in addition to restructuring activities.  Furthermore, non-recurring costs associated with the merger in 2016 did not repeat in the current year.
• Net loss from continuing operations for the quarter ended September 30, 2017, was $15.7 million or a loss of $0.12 per share, compared with net loss of $33.6 million or $0.31 per share in the same period last year.  This improvement is driven by higher gross margin, lower operating expenses, and higher CWI income compared to the same period last year.

"The company continues to effectively manage its working capital and ongoing liquidity," said Ashoka Achuthan, Chief Financial Officer of Westport Fuel Systems. “In the third quarter, our balance sheet was strengthened by the proceeds received from the equity issuance in July and the repayment of the $55M CDN debentures on September 15, 2017. Revenue growth year-overyear was driven by our core business and bolstered by the strong Euro. We remain focused on aligning our costs to our revenues and with this quarter's performance, we are moving closer to achieve positive adjusted EBITDA."

Cummins Westport Inc. Highlights

• Revenue was $75.5 million on 1,780 units for the quarter ended September 30, 2017, an increase of 12% over the same period last year.  This is driven by strong customer demand as volume grew by 8% year-over-year; enhanced by higher parts revenue attributed to the increase of in-service natural gas engines.
• Gross margin for the quarter ended September 30, 2017 increased by $5.9 million to 27.9 million, or 37% of revenue from $22.0 million or 33% of revenue in the prior year quarter. The increase in gross margin and gross margin percentage is driven by higher revenues, a more favorable parts revenue mix, and a positive warranty adjustment.
• CWI operating income for the quarter ended September 30, 2017 was $14.9 million, a significant increase from the prior year primarily due to improvement in gross margin and lower operating expenses, driven by reduction in marketing expense and timing of the on-board diagnostics compliance spending that is nearing completion.

GAAP and NON-GAAP FINANCIAL MEASURES

Management reviews the operational progress of its business units and investment programs over successive periods through the analysis of net income, EBITDA and Adjusted EBITDA. The Company defines EBITDA as net loss from continuing operations before income taxes adjusted for interest expense (net), depreciation and amortization. Westport Fuel Systems defines Adjusted EBITDA as EBITDA from continuing operations excluding expenses for stock-based compensation, unrealized foreign exchange gain or loss, and non-cash and other adjustments. Management uses Adjusted EBITDA as a long-term indicator of operational performance since it ties closely to the business units’ ability to generate sustained cash flow.  Adjusted EBITDA includes the company's share of income from joint ventures.

The term Adjusted EBITDA is not defined under U.S. generally accepted accounting principles ("U.S. GAAP") and is not a measure of operating income, operating performance or liquidity presented in accordance with U.S. GAAP. Adjusted EBITDA has limitations as an analytical tool, and when assessing the company's operating performance, investors should not consider Adjusted EBITDA in isolation, or as a substitute for net loss or other consolidated statement of operations data prepared in accordance with U.S. GAAP. Among other things, Adjusted EBITDA does not reflect the company's actual cash expenditures. Other companies may calculate similar measures differently than Westport Fuel Systems, limiting their usefulness as comparative tools. The company compensates for these limitations by relying primarily on its U.S. GAAP results and using Adjusted EBITDA as supplemental information.
