Letter to Shareholders

I have had the privilege to be Westport’s CEO for just over a year now and wanted to take 
a moment to reflect on the remarkable progress we have made over that time and provide 
a view into our plans and expectations for 2025. The past year was a transformative period 
for the Company. I am proud of the strides we have made in our commitment to advancing 
technologies, services and products that reduce emissions, enhance efficiencies, and promote 
a sustainable future. Westport is working to ensure that customers have affordable solutions to 
meet their commercial and environmental goals. As Westport’s leader, I am motivated to not 
only achieve our short- and long-term goals but to make a significant positive difference in the 
transport industry.  
Key Accomplishments 
2024 was a strong year for Westport. 
We strengthened an important 
alliance, tightened the alignment 
between our competitive strategy and 
our internal operations, and made 
substantial efficiency improvements 
that have enhanced our cost structure. 
Last year, we saw our gross margin 
improve, increasing from 9% in Q4 of 
2023 to 19% in Q4 of 2024. We also demonstrated a significant $20.4 million improvement in 
our net cash provided by operating activities to $7.2 million for the year ended December 31, 
2024, representing one of the first times Westport has generated positive cash from operations. 
 
In June, we advanced cleaner commercial transport through the beginning of our joint venture 
with Volvo Group, named Cespira. And in March 2025, we announced the proposed divestiture 
of our Light-Duty business, which is expected to strengthen our balance sheet and focus 
Westport on its competitive strengths, to meet the diverse market needs for effective solutions 
to decarbonize hard-to-abate applications in the transport space utilizing alternative fuels. 
 
 I am committed to 
producing results, 
driving productivity, 
and enhancing value 
for shareholders.

To be successful on an annual basis, Westport needs to continue to deliver on our purpose, 
be disciplined in our operations and align our decision-making to a strong strategic plan. 
Accordingly, over the past year we executed against our three strategic priorities; driving 
success via the HPDI joint venture, improved operational excellence and shaping a future 
powered by alternative fuels, all while evolving with intent, and prudent financial stewardship.  
Crystalized our Strategic Relationship with Volvo Group 
Our joint venture with Volvo Group, named Cespira, 
has begun its journey toward the decarbonization 
of heavy transport. The joint venture, which began 
operations in June of 2024, aims to expand the 
availability of the High-Pressure Direct Injection 
(“HPDITM”) fuel system, with carbon neutral fuels like hydrogen and renewable natural gas as 
its propellants. The formation of the partnership was an important milestone for Westport 
and a true endorsement of our HPDI technology and fuel system. 
Acting Today, Shaping Tomorrow
Westport is ‘Driving Cleaner Performance’ with practical yet innovative applications available 
today, to shape a sustainable and responsible transportation industry long into the future. 
We believe that 2025 will be another eventful year on our journey to create technologies that 
not only reduce emissions and enhance efficiency for customers but also to highlight our 
dedication to a future of alternative fuels. However, it’s clear that our target markets are in a 
state of change. We are seeing global and economic pressures leading to turbulence in the 
automotive sector, which is coinciding with a slowdown in the hydrogen market and volatility 
in the passenger car market. While we are persevering through these challenging times, we 
are taking this opportunity to reposition the Company. We have many opportunities in front 
of us and are determined to forge a path to capitalize on a promising current set of emerging 
prospects. Ultimately, we are striving to ensure that our customers have access to affordable 
solutions that help them achieve their commercial and environmental goals, now and for 
many years to come.

Providing Solutions for Hard to Decarbonize 
Transport and Industrial Applications  
In early 2025, Westport announced its intention to divest of its Light-Duty business. I am 
confident the proposed disposition enhances long-term value for Westport shareholders 
by creating a focused company dedicated to providing solutions to decarbonize hard-
to-abate mobility and industrial applications. Following the divestiture, Westport will 
be structured to execute against a distinct value proposition with the ability to pursue 
and achieve greater success. This includes tailored strategies targeted at driving and 
leveraging fuel agnostic technologies today, to create mature, affordable zero emissions 
hydrogen solutions tomorrow. 
Despite technological advancements, decarbonizing long-haul heavy-duty transport 
remains a challenge, with substantial reductions in CO2 emissions still to be realized. 
Original Equipment Manufacturers have explored multiple alternatives, yet widespread 
adoption has been limited. Fleet operators are prioritizing cost-effectiveness and total 
cost of ownership, with emissions often taking a secondary role. Hydrogen is recognized 
as a solution for long haul applications, but its adoption timeline is uncertain. Meanwhile, 
demand continues to grow for low- and zero-carbon alternatives in hard to decarbonize 
applications, such as heavy-duty trucking. However, for solutions to gain traction, they 
must maintain performance and be cost-effective.  
To address these challenges, Westport is advancing fuel-agnostic technologies, growing 
its natural gas solutions today, while laying the groundwork for hydrogen adoption in 
the future. In 2025, we plan to continue building on our alternative fuel technology, 
including, but not limited to, CNG components and application advancements and RNG 
systems growth, aiming to scale production and enhance commercialization of hydrogen 
fuel systems for a wide range of transportation applications. In addition, the HPDI fuel 
system is the most affordable commercially viable option that does not compromise on 
performance and that can deliver net zero carbon emissions in heavy duty transport. As 
more difficult to decarbonize applications emerge in the transport sector, high pressure 
systems and controls will be required regardless of the powertrain, and they complement 
the transition from natural gas to renewables to hydrogen. Westport components and 
solutions are already powering emission-reducing innovations today, across a range of 
alternative fuels, including natural gas, renewable natural gas, and hydrogen.

DAN SCELI, 
CEO & Director
The resurgence of natural gas and renewable natural gas globally provides a market 
opportunity for Westport, particularly in North America where natural gas infrastructure 
is abundant and RNG production is growing. We believe that hydrogen will play a role in 
‘hard to decarbonize’ mobility applications, although the timeline is uncertain and has 
lengthened recently. However, Westport’s products are timeline-agnostic, leveraging our 
High-Pressure Controls & Systems segment and stake in Cespira which have solutions 
available now, to address decarbonization with net zero fuels and low carbon fuels while 
also having the most affordable solutions when zero carbon hydrogen becomes more 
available, with a clear focus on the ecosystem surrounding the HPDI fuel system and our 
Cespira JV.  
To ensure that we are positioned as a key player in this rapidly growing and changing 
market, we also must focus on our financial strength. We remain committed to 
strengthening our balance sheet to enable us to fund the growth that will deliver value 
to our shareholders. With a focus on cost controls, operational excellence, and prudent 
capital allocation, in addition to the opportunities we see in front of us, we are excited to 
position ourselves at the forefront of this transformative shift.
Conclusion  
The improvements that we’ve embraced over the past year have positioned us to deliver 
more affordable and sustainable solutions that help our customers meet their commercial 
and environmental goals. I am proud of what we accomplished in 2024 and am grateful 
for your continued support. As your CEO, I am committed to producing results, driving 
productivity, and enhancing value for shareholders. We are optimistic about 2025’s 
opportunity set, as we work to leverage our core capabilities from our roots, advance clean 
technology solutions, and contribute to a more sustainable future.

BUSINESS OVERVIEW
Headquartered in Vancouver, British Columbia, Canada, with operations in Europe, Asia, North 
America, and South America, Westport serves customers in approximately 70 countries with leading 
global transportation brands through a network of distributors, service providers for the aftermarket 
and direct to Original Equipment Manufacturers (“OEMs”) and Tier 1 and Tier 2 OEM suppliers. 
With a focus on engineering, manufacturing, and supplying alternative fuel systems and components 
for transportation applications, Westport’s diverse product offerings, sold under a wide range of 
established global brands, enable the use of a number of alternative fuels in the transportation sector 
that provide environmental and/or economic advantages as compared to diesel, gasoline, or battery 
powered electric vehicles. 
Westport designs, manufactures, develops, validates, certifies, and sells alternative fuel (including 
alternative fuels such as hydrogen (“H2”), liquefied natural gas (“LNG”), biogas, biomethane, and 
renewable natural gas (collectively “RNG”), compressed natural gas (“CNG”), and liquefied petroleum 
gas (“LPG”) components and systems for passenger cars and light-, medium- and heavy-duty 
commercial vehicles and off-highway applications.
Our portfolio of products includes pressure regulators, injectors, electronic control units, valves and 
filters, complete bi-fuel, mono-fuel and dual-fuel LPG and natural gas conversion kits and high-
pressure hydrogen components. Cespira, our 55% owned joint venture (“JV”) with the Volvo Group 
("Volvo"), launched in 2024, is advancing the development and commercialization of the HPDITM fuel 
system, a fully OEM-integrated solution that enables heavy-duty trucks to operate on natural gas, 
RNG, hydrogen and other alternative fuels. 
Business Segments
Our diverse portfolio of technologies, products, and services are sold under a wide range of 
established brands. They provide the foundation for sustainable growth in existing markets and guide 
our expansion into new and emerging markets worldwide. Our business is operated under the 
following four segments:
13

Cespira 
In June 2024, Westport and Volvo entered into a series of joint venture agreements (collectively, the 
"JV Agreement"), establishing Cespira to promote, develop, and commercialize the HPDI fuel system 
technology (see Material Contracts – Joint Venture Governance Agreements). The JV will prioritize 
scaling the HPDI fuel system and supporting the global transition to carbon-neutral fuel systems, 
particularly in heavy-duty, long-haul trucking, where multiple technologies are required to achieve 
substantial decarbonization. Under the terms of the agreement, Westport owns a 55% equity interest 
in Cespira, while Volvo owns 45%. Cespira's business operations involve supplying systems, 
engineering services and components, including LNG HPDI fuel system products, to engine 
manufacturers and commercial vehicle OEMs. The fully integrated LNG HPDI fuel systems enable 
diesel engines to operate predominantly on alternative fuels while delivering equivalent power, 
torque, and fuel efficiency as conventional compression ignition engines. The system can be a cost-
effective way to reduce greenhouse gas emissions using renewable fuels such as RNG. Furthermore, 
the JV is engaged in adapting HPDI fuel systems for hydrogen and other alternative fuel applications 
in internal combustion engines.
Light-Duty 
The Light-Duty segment specializes in LPG and CNG solutions, including fuel storage tanks, catering 
to OEM, delayed OEM (“DOEM”), and independent aftermarket (“IAM”) markets. Customers can 
choose from Westport IAM conversions, DOEM solutions, or OEM-manufactured mono-fuel and bi-
fuel vehicles. The segment offers industry-leading direct injection engine technology that complies 
with EURO 7 and EPA 24 standards, along with lightweight, high-quality fuel storage solutions.
The Light-Duty business serves three distinct markets: 
1.
OEM: Systems are integrated into production lines by vehicle manufacturers.
2.
DOEM: Conversions are performed at 0 km in specialized centers operated by Westport or its
partners.
3.
IAM: Aftermarket products, including conversion kits, support post-sale conversions through
an extensive dealer and installer network operating in approximately 70 countries worldwide.
Westport works to distinguish itself as a global company that integrates and manufactures 
mechanical components, electronics, and fuel storage systems, providing a seamless and efficient 
solution for our customers.
High-Pressure Controls and Systems
Our High-Pressure Controls and Systems segment is at the forefront of the clean energy revolution, 
designing, developing, and producing high-demand components for transportation and industrial 
applications. We partner with the world's leading fuel cell, hydrogen engine and alternative fuel 
engine manufacturers and companies committed to decarbonizing transport, offering versatile 
solutions that serve a variety of fuel types. While hydrogen is key to the future decarbonization of 
transport, our components and solutions are already powering emission-reducing innovation today 
across a range of alternative fuels. While we are a small enterprise, our strategic position and 
innovative capabilities put us on the cusp of significant growth, ensuring we are the go-to choice for 
those shaping the future of clean energy, today and tomorrow.
Heavy-Duty OEM 
Our Heavy-Duty OEM business represents historical results from our heavy-duty business for the 
period January 1, 2024, until the formation of the Cespira joint venture which occurred on June 3, 2024. 
Going forward, the Heavy-Duty OEM segment will reflect revenue earned from a transitional services 
agreement in place with Cespira, intended to support the JV in the short-term as the organization 
establishes its operations.
14

RISKS, LONG-TERM PROFITABILITY & LIQUIDITY
Government Regulation and Inflationary Environment
Government regulation is a key factor in driving accelerated global demand and adoption of reduced 
emission vehicles. Supportive government policy combined with rising corporate adherence to 
emission reduction goals are creating growth catalysts for Westport in some of its key markets. While 
we have benefited historically from certain government environmental policies, mandates and 
regulations around the world, there can be no assurance that these policies, mandates, and 
regulations will be continued. If these are discontinued, if current requirements are relaxed, or if other 
regulations are implemented that may impact our business, we may experience a material impact on 
our competitive position.
Global inflation trends remain inconsistent, with inflationary pressures easing in developed countries, 
while continuing to impact certain emerging and developed markets. In key LPG markets such as 
Poland, Turkey, and Italy, LPG prices have experienced upward pressure. Westport sources its 
components from global suppliers and continues to face inflationary pressure on production input 
costs. Specifically, the cost of semiconductors, raw materials, and parts has increased, along with 
higher labor costs, all of which are contributing to margin compression.
Increased Interest Rates
In response to inflationary pressures, central banks in major markets have raised interest rates to 
multi-decade highs. While some regions, including Canada, the United States, and Europe, have 
begun reducing rates, current levels remain restrictive and are having a significant impact on both the 
automotive and clean energy sectors.
Automotive manufacturers and OEMs are facing challenges as higher interest rates are compressing 
profit margins. This environment is leading to delays and cancellations of clean energy investments as 
companies prioritize cost-cutting measures. Additionally, elevated interest rates have contributed to a 
slowdown in global economic growth, particularly in emerging markets where economic conditions 
are already volatile, are facing heightened financial pressures, which could further dampen demand 
for clean energy solutions.
Hydrogen Eco-System Uncertainty
The hydrogen industry is currently facing economic challenges associated with limited load of 
available hydrogen which has resulted in high operational costs across the value chain. This has led to 
delays and cancellations of projects. Key cost factors, such as rising renewable electricity prices and 
increased electrolyzer costs, are having a significant impact on the economics of renewable (green) 
hydrogen projects. These higher costs, coupled with uncertainties surrounding fuel supply and 
infrastructure development, make it challenging to predict when hydrogen technology for transport 
will become a viable decarbonization solution.
Fuel Prices
European natural gas prices, although elevated recently, are still significantly below the record highs 
of 2022. Lower demand, influenced by reduced economic activity and previous mild weather, has 
contributed to price moderation. Additionally, the diversification of gas imports continues to be a key 
focus of European energy policy. Long-term forecasts suggest that natural gas prices will remain well 
below 2022 peaks. This outlook reinforces the fuel’s cost-effectiveness and its role in advancing the 
transition to natural gas-powered vehicles
Refer to our discussion in our AIF "Near-Term Industry Challenges" and "Industry Growth Drivers" for 
more information.

Liquidity and Going Concern
We believe that we have considered all possible impacts of known events arising from the risks 
discussed above related to supply chain, and fuel prices in the preparation of the annual financial 
statements for the year ended December 31, 2024. However, changes in circumstances due to the 
forementioned risks could affect our judgments and estimates associated with our liquidity and other 
critical accounting assessments.  
For the year ended December 31, 2024, we continue to sustain operating losses and use cash to 
support our business activities. Cash provided by operating activities was $7.2  million for the year 
ended December 31, 2024 and was primarily driven by reductions in working capital.
As at December 31, 2024, we had cash and cash equivalents of $37.6 million and long-term debt of 
$33.7  million, of which $14.7  million was current. Based on our projected capital expenditures, debt 
servicing obligations and operating requirements under our current business plan, we are projecting 
that our cash and cash equivalents will not be sufficient to fund our operations through the next 
twelve months from the date of the issuance of this MD&A. These conditions raise substantial doubt 
about Westport's ability continue as a going concern within one year after the date of this MD&A is 
issued.
We plan to improve our liquidity position by selling certain subsidiaries in Europe and Argentina 
which comprise substantially all the assets and liabilities of the Light-Duty segment and continue our 
cost reduction initiatives. On March  30, 2025, we entered into a share purchase agreement ("SPA") 
with a wholly-owned investment vehicle of Heliaca Investments, a Netherlands based investment firm 
supported by Ramphastos a prominent Dutch venture capital and private equity firm, to sell all of the 
issued and outstanding shares of Westport Fuel Systems Italia S.r.l. The transaction provides for a base 
purchase price of $73.1 million (€67.7 million), subject to certain adjustments and potential earnouts of 
up to an estimated $6.5 million (€6.0 million) if certain conditions are achieved, in accordance with the 
terms of the SPA. If we are successful in closing the sale, we will receive sufficient cash to fund our 
operations for the next twelve months and alleviate the risk of substantial doubt identified. As of the 
date of issuance of these financial statements, we are seeking shareholder approval of the plan to 
complete the sale of these businesses to the buyer. As such, there can be no assurances that Westport 
will be successful in obtaining sufficient funding. Accordingly, we concluded under the accounting 
standards that these plans do not alleviate the substantial doubt about Westport's ability to continue 
as a going concern.
OVERVIEW OF FINANCIAL RESULTS FOR 2024
Revenues for the year ended December 31, 2024 decreased by 9% to $302.3 million compared to $331.8 
million in the prior year, primarily driven by the transition of the Heavy-Duty OEM business into 
Cespira, partially offset by an increase in revenue in our Light-Duty segment. 
We reported a net loss of $21.8 million for the year ended December 31, 2024 compared to a net loss of 
$49.7 million for the prior year. The net positive change was primarily the result of: 
•
improvements in gross profit for the year ended December 31, 2024 of $8.7 million compared
to the prior year
•
$15.2 million gain on deconsolidation of the HPDI business arising from the formation of the
joint venture with Volvo Group on June 3, 2024
•
reductions in operating expenditures and depreciation and amortization expense due to
deconsolidation of the HPDI business
•
partially offset by higher income tax expense and foreign exchange losses in the year.
Cash and cash equivalents were $37.6 million as at December 31, 2024. Cash provided by operating 
activities during the year was $7.2 million, primarily from a positive reduction in working capital of 
16

$16.4 million. Cash provided by investing activities comprise the sale of investments for a total of $30.0 
million, which includes proceeds received from the sale of 45% ownership interest in Cespira to Volvo, 
sale of our remaining interest in WWI, and 26% interest in Minda Westport Technologies Limited 
("MWTL"), partially offset by the purchase of capital assets of $16.9 million, and $9.9 million in capital

RESULTS FROM OPERATIONS
REPORTABLE SEGMENTS
Westport discloses segment information under four reportable segments, consistent with the manner 
in which its Chief Operating Decision Maker ("CODM") evaluates its businesses. The Company's CODM 
is its Chief Executive Officer. These segments are the strategic pillars of the Company and are 
managed separately as each represents a specific grouping of related automotive components and 
systems. The reportable segments are further described below. In prior years, Westport presented its 
results 
under 
2 
reportable 
segments: 
Independent 
aftermarket 
and 
Original 
equipment 
manufacturer. 
18

Effective June 3, 2024, the Company changed how it evaluates and manages its businesses as a result 
of the deconsolidation of its former HPDI business and formation of the joint venture. Westport now 
reports its results in the following four reportable segments: Light-Duty, High-Pressure Controls & 
Systems, Heavy-Duty OEM, and Cespira. The prior year comparatives were recast to reflect this change 
in reportable segments.
Segment earnings or losses before income taxes, interest, depreciation, and amortization ("Segment 
EBITDA") is the measure of segment profitability used by the Company. The accounting policies of our 
reportable segments are the same as those applied in our consolidated financial statements. 
Management prepared the financial results of the Company's reportable segments on basis that is 
consistent with the manner in which Management internally disaggregates financial information to 
assist in making internal operating decisions. Certain common costs and expenses, primarily 
corporate functions, among segments differently than we would for stand-alone financial information 
prepared in accordance with GAAP. These include certain costs and expenses of shared services, such 
as IT, human resources, legal, finance and supply chain management.  Segment EBITDA is not defined 
under US GAAP and may not be comparable to similarly titled measures used by other companies 
and should not be considered a substitute for net earnings or other results reported in accordance 
with GAAP. Reconciliations of reportable segment information to consolidated statement of 
operations can be found in section "NON-GAAP FINANCIAL MEASURES & RECONCILIATIONS" within 
this MD&A.

Light-Duty
Revenue for the three months and year ended December 31, 2024 was $68.0 million and $262.2 
million, respectively, compared with $63.4 million and $263.6 million for the three months and year 
ended December 31, 2023. 
Light-Duty revenue increased by $4.6 million for the three months ended December 31, 2024 
compared to the prior year. This was primarily driven by a significant increase in sales of LPG fuel 
system solutions to a global OEM for Euro 6 vehicle applications in our light-duty OEM business and 
an increase in DOEM business, partially offset by lower revenues in other business lines.
Light-Duty revenue decreased by $1.4 million for the year ended December 31, 2024 compared to the 
prior year. This was primarily driven by a decrease in sales in our DOEM business in the first half of 
2024, decrease in sales to customers in developing markets and our fuel storage business. This was 
partially offset by the aforementioned increase in sales of LPG fuel system solutions in our light-duty 
OEM business.
High-Pressure Controls & Systems
Revenue for the three months and year ended December 31, 2024 was $1.4 million and $8.8 million, 
respectively, compared with $2.5 million and $12.0 million for the three months and year ended 
December 31, 2023.
Revenue for the three months ended December 31, 2024 decreased by $1.1 million compared to the 
prior year period.
Revenue for the year ended December 31, 2024 decreased by $3.2 million compared to the prior year.
20

The decrease in revenue for the three months and year ended December 31, 2024 compared to the 
prior year periods continues to be primarily driven by the general slowdown in the hydrogen 
infrastructure development, leading to a slower adoption of automotive and industrial applications 
powered by hydrogen.
Heavy-Duty OEM
Revenue for the three months and year ended December 31, 2024 was $5.7 million and $31.3 million, 
respectively, compared to $21.3 million and $56.2 million for the comparative periods.
The decrease in revenue for the three months and year ended December 31, 2024 is a result of the 
continuation of the business in Cespira. Refer to the "Selected Cespira Statement of Operations 
information" within this MD&A for more information on the performance of the HPDI business. 
Revenue for the three months ended December 31, 2024 reflects revenue from our transitional 
services agreement with Cespira that we expect to expire by the end of Q2 2026.

change in sales mix with an increase in sales to European customers and a reduction in sales to 
developing regions. The segment's manufacturing operations continues to implement operational 
improvement initiatives lowering its manufacturing overhead costs in the year. For the year ended 
December 31, 2024, Light-Duty recorded inventory write-downs of $2.1 million related to our

Foreign exchange gains and losses reflect net realized gains and losses on foreign currency 
transactions and net unrealized gains and losses on our net U.S. dollar denominated monetary assets 
and liabilities in our Canadian operations that were mainly comprised of cash and cash equivalents, 
accounts receivable and accounts payable. In addition, we have foreign exchange exposure on Euro 
denominated monetary assets and liabilities where the functional currency of the subsidiary is not the 
Euro. For the year ended December 31, 2024, we recognized a foreign exchange loss of $6.2 million 
compared to a foreign exchange loss of $4.0 million for the year ended December 31, 2023. The loss 
recognized in the current year primarily relates to unrealized foreign exchange losses resulting from 
the remeasurement of U.S. dollar denominated debt in our Canadian legal entities.
Depreciation and amortization for the years ended December 31, 2024 and December 31, 2023 were 
$8.7 million and $12.5  million, respectively. Depreciation and amortization decreased year-over-year, 
primarily driven by the transition of the HPDI business into Cespira on June 03, 2024.
Income (loss) from investments accounted for by the equity method for the years ended 
December  31, 2024 and December  31, 2023 were loss of $5.4 million and income of $0.8 million, 
respectively. This is primarily driven by our 55% ownership interest in Cespira and our 24% ownership 
interest in MWTL.

Interest expense on long-term debt for the three months ended and for the year ended December 31, 
2024 compared to prior year periods were consistent due to the rate cuts in the U.S. prime rate 
lowering our interest expense in our EDC term loan, partially offset by additional interest expense 
from a new term loan borrowed in the beginning of the year with UniCredit.
Income tax expense for the year ended December 31, 2024 was $5.0 million compared to $1.0 million 
in the prior year. The increase in income tax expense was primarily driven by increase in taxes from 
higher profitability in our European operations.

CAPITAL REQUIREMENTS, RESOURCES AND LIQUIDITY
Our cash and cash equivalents position decreased by $17.2 million to $37.6 million at December  31, 
2024 compared to $54.9 million at December 31, 2023. The decrease in cash was primarily driven by 
our debt repayments, partially offset by cash provided by our operating and investing activities.
Cash Flow from Operating Activities 
For the year ended December 31, 2024, net cash provided by operating activities was $7.2 million 
compared to net cash used of $13.2 million for the year ended December  31, 2023, a $20.4 million 
increase in net cash provided by operating activities. The increase in net cash provided by operating 
activities was primarily driven by a reduction in operating losses of $21.2 million, and an improvement 
in working capital, specifically in accounts receivable and accounts payable partially offset by 
increases in prepaid expenses and inventory, and a reduction in warranty liability.
Cash Flow from Investing Activities
For the year ended December 31, 2024, our net cash provided by investing activities was $4.5 million 
compared to net cash used of $15.4 million for the year ended December 31, 2023. The increase in net 
cash provided by investing activities was primarily driven by proceeds from sale of investments of 
$30.0 million, partially offset by purchases of property, plant and equipment of $16.9 million  and 
capital contributions to Cespira of $9.9 million in the year ended December 31, 2024. Proceeds from 
sale of investments include cash proceeds of $27.3 million from Volvo for the purchase of a 45% 
ownership interest in Cespira as part of the formation of the joint venture.
Cash Flow from Financing Activities
For the year ended December 31, 2024, our net cash used in financing activities was $25.2 million, 
compared to net cash used in financing activities of $2.2 million during the year ended December 31, 
2023. On January 10, 2024, we borrowed from UniCredit a new term loan of $3.8 million with principal 
repayments starting in 2025. On November 30, 2024, we closed our revolving financing facility with 
Royal Bank of Canada and reduced our use of the credit facility in the year. In the prior year, we fully 
repaid our royalty payable to Cartesian.

SHARES OUTSTANDING
On September 13, 2024,  we announced an at-the-market equity offering program (the "ATM 
Program") that allows us to issue up to $35.0 million in common shares from treasury to the public 
from time to time, at our discretion and subject to regulatory requirements. As at December 31, 2024 
and the date of issuance of this MD&A, no shares were issued from treasury related to the ATM 
Program.
For the year ended December 31, 2024, the weighted average number of shares used in calculating 
net loss per share was 17,248,090. During the year ended December 31, 2024, 224,050 share units were 
granted to directors, executives and employees (2023 - 435,128 share units). This included 104,215 
Restricted Share Units ("RSUs") (2023 - 147,557 RSUs), nil Performance Share Units ("PSUs") (2023 - 
185,365 PSUs) and 119,835 Deferred Share Units (2023 - 102,206 DSUs). The common shares, share 
options and share units outstanding and exercisable as at the following dates are shown below:

CRITICAL ACCOUNTING POLICIES AND ESTIMATES
Our Annual Financials Statements are prepared in accordance with U.S. GAAP, which requires us to 
make estimates and assumptions that affect the amounts reported in our Annual Financial 
Statements. We have identified several policies as critical to our business operations and in 
understanding our results of operations. These policies, which require the use of judgment, estimates 
and assumptions in determining their reported amounts, include the assessment of accounts 
receivable, liquidity and going concern, warranty liability, revenue recognition, inventories, and 
property, plant and equipment. The application of these and other accounting policies are described 
in note 3 of the Annual Financial Statements. Actual amounts may vary significantly from estimates 
used.
Variable interest entities ("VIEs") and Gain on deconsolidation
We identified HPDI Technology LP and HPDI Technology AB as VIEs, as the entities are dependent on 
funding from its owners. The funding and ownership interests of the entities are split on a 55/45 basis 
between the owners of the VIEs. The voting rights and power to exercise control is shared equally on a 
50/50 basis between the owners of the VIEs. Therefore, we have determined that we are not the 
primary beneficiary of the VIEs. We account for our investment in VIEs for which we are not primary 
beneficiaries of using the equity method of accounting. 
Identifying a VIE and determining the primary beneficiary of a VIE requires the use of our judgment, 
estimates, and assumptions including determining the most significant activities and decisions that 
impact the economic performance of a VIE and the beneficiary who has the power over those 
decisions. If events and circumstances change in a VIE, it may have a significant impact in how we 
account for the entity.
When a legal entity is no longer consolidated by the parent company, a gain or loss is recognized 
upon deconsolidation based on the considerations received for the transaction less any net assets 
disposed and any contingent liabilities incurred. Considerations received may include cash 
consideration, net assets received, and any contingent considerations (e.g., earnout) included in the 
arrangement. Accounting for contingent considerations relies on our judgment, estimates, and 
assumptions including whether a contingent consideration should be considered a derivative. The 
potential earnout from the formation of our Cespira joint venture (note 5 in our consolidated financial 
statements) was not identified as a derivative and we have elected to account for the contingent 
consideration using the loss recovery approach. Under this approach, we did not recognize any 
contingent receivable at inception and will recognize a contingent gain when such gain is realized or 
realizable.
Revenue Recognition 
We generate revenues primarily from product sales. Product revenues are derived primarily from 
standard product sales contracts and from long-term fixed price contracts. Under ASC 606, revenue is 
recognized when a customer obtains control of the goods or services. Determining the timing of the 
transfer of control, at a point in time or over time, requires judgment. On standard product sales 
contracts, revenues are recognized when customers obtain control of the product, that is when 
transfer of title and risks and rewards of ownership of goods have passed and when the obligation to 
pay is considered certain. Invoices are generated and revenue is recognized at that point in time. 
Provisions for warranties are made at the time of sale.
Accounts Receivable
We make assumptions and have established current expected credit losses ("CECL") for pools of assets 
with similar risk characteristics by evaluating historical levels of credit losses, current economic 
conditions that may affect a customer's ability to pay, and creditworthiness of significant customers. 
When specific customers are identified as no longer sharing the same risk profile as their current pool, 
28

they are removed from the pool and evaluated separately. When we become aware of a customer’s 
inability to meet its financial obligation, we record a specific credit loss provision to reduce the 
customer's related accounts receivable to its estimated net realizable value.
Inventories
Our inventories consist of our fuel system products (finished goods), work-in-progress, purchased 
parts and materials. Inventories are recorded at the lower of cost and net realizable value. The cost of 
fuel system product inventories, assembled parts and work-in-progress includes materials, labour and 
production overhead including depreciation. We record inventory write-downs based on an analysis 
of excess and obsolete inventories determined primarily by future demand forecasts. In addition, we 
record a liability for firm, non-cancelable, and unconditional purchase commitments with 
manufacturers for quantities in excess of our future demand forecast consistent with our valuation of 
excess and obsolete inventory.
Property, plant, & equipment ("PP&E") and Intangible Assets
We consider whether or not there has been an impairment in our long-lived assets, such as plant and 
equipment, furniture and leasehold improvements and intangible assets, whenever events or 
changes in circumstances indicate that the carrying value of the assets may not be recoverable. If 
such assets are not recoverable, we are required to write down the assets to fair value. When quoted 
market values are not available, we use the expected future cash flows discounted at a rate 
commensurate with the risks associated with the recovery of the asset as an estimate of fair value to 
determine whether or not a write down is required.
Impairment of PP&E 
We have significant investments in PP&E related to our Light-Duty business. The Light-Duty business 
has significant manufacturing operations in Italy and Poland. The Light-Duty business has historically 
been profitable including for the year ended December 31, 2024. As of December 31, 2024, we have 
concluded that there are no impairment indicators.
Impairment of Intangible assets
We concluded that there were no impairment indicators as of December 31, 2024 related to intangible 
assets. Therefore, no impairment on intangible assets was recorded in the year ended December 31, 
2024.
NEW ACCOUNTING PRONOUNCEMENTS AND DEVELOPMENTS
New accounting standard adopted in 2024:
In November 2023, the Financial Accounting Standards Board ("FASB") issued Accounting Standards 
Update ("ASU") 2023-07, "Segment Reporting (Topic 280): Improvements to Reportable Segment 
Disclosures." It requires incremental disclosures related to an entity's reportable segments, including:
(i) significant segment expense categories and amounts for each reportable segment that are
provided to the Chief Operating Decision Maker ("CODM"),
(ii) an aggregate amount and description of other segment items included in each reported
measure,
(iii) all annual disclosures about a reportable segment's profit or loss and assets required by
Topic 280 to be disclosed in interim periods,
(iv) the title and position of the individual or name of the group identified as the CODM, and
(v) an explanation of how the CODM uses the reported measures of segment profit or loss to
assess performance and allocate resources to the segment.
29

The standard improves transparency by providing disaggregated expense information about an 
entity's reportable segments. The standard does not change the definition of a segment, the method 
for determining segments or the criteria for aggregating operating segments into reportable 
segments. The Company has adopted this guidance in the current year reported and provided 
additional comparative disclosures as required. Refer to Note 22 "Segment Information" of the Annual 
Financial Statements for more information.
Upcoming accounting standards not yet adopted in 2024:
In December 2023, the FASB issued ASU 2023-09, "Income Taxes (Topic 740): Improvements in Income 
Tax Disclosures" to enhance the transparency and decision usefulness of income tax disclosures. This 
amendment requires public companies to disclose specific categories in the rate reconciliation and 
provide additional information for reconciling items that meet a quantitative threshold. Additionally, 
under the amendment entities are required to disclose the amount of income taxes paid 
disaggregated by federal, state and foreign taxes, as well as disaggregated by material individual 
jurisdictions. Finally, the amendment requires entities to disclose income from continuing operations 
before income tax expense disaggregated between domestic and foreign and income tax expense 
from continuing operations disaggregated by federal, state and foreign. This guidance is effective for 
annual reporting periods beginning after December 15, 2024. While this guidance may have an impact 
on the disclosures, the Company does not expect this guidance to have a material impact on its 
financial position, operations, and cash flows.
In November 2024, the FASB issued ASU 2024-03, "Income Statement - Reporting Comprehensive 
Income - Expense Disaggregation Disclosures (Subtopic 220-40): Disaggregation of Income 
Statement Expenses." It requires entities to disclose, in the notes to the financial statements, specified 
information related to certain costs and expenses disaggregated by type. The standard improves 
transparency by providing more detailed information about the component of costs and expenses 
that would enable users to better understand the major components of an entity's income statement 
by referencing disclosures in the notes to financial statements. This guidance is effective for annual 
reporting periods beginning after December 15, 2026. While this guidance may have an impact on the 
disclosures, the Company does not expect this guidance to have a material impact on its  financial 
position, operations, and cash flows.

DISCLOSURE CONTROLS AND PROCEDURES AND INTERNAL CONTROLS OVER FINANCIAL 
REPORTING
Evaluation of Disclosure Controls and Procedures
Our disclosure controls and procedures, as defined in Rules 13a-15(e) and 15d-15(e) of the Securities 
Exchange Act of 1934, as amended ("Exchange Act"), are designed to provide reasonable assurance 
that information required to be disclosed in the reports that we file or submit under the Exchange Act 
and applicable Canadian securities law requirements is recorded, processed, summarized and 
reported within the time periods specified in the SEC's rules and forms and applicable Canadian 
securities law requirements, and that such information is accumulated and communicated to our 
management, including our Chief Executive Officer ("CEO") and Chief Financial Officer ("CFO") (our 
principal executive officer and principal financial officer, respectively), as appropriate to allow timely 
decisions regarding required disclosures.
We evaluated the effectiveness of our internal controls over financial reporting as of December  31, 
2024 with the participation, and under the supervision of our management, including our CEO and 
CFO. Based upon this evaluation, our CEO and CFO concluded that as of December  31, 2024, our 
internal controls and procedures over financial reporting were effective for the period. 
Management's Report on Internal Control Over Financial Reporting 
Our management is responsible for establishing and maintaining adequate internal control over 
financial reporting, as such term is defined in Rule 13a-15(f) and 15d-15(f) under the Exchange Act. 
Internal control over financial reporting is a process designed by, or under the supervision of, our CEO 
and CFO and effected by our board of directors, management, and other personnel, to provide 
reasonable assurance regarding the reliability of financial reporting and the preparation of our 
consolidated financial statements for external reporting purposes in accordance with U.S. GAAP and 
the requirements of the SEC, as applicable. There are inherent limitations in the effectiveness of 
internal control over financial reporting, including the possibility that misstatements may not be 
prevented or detected.
Because of these inherent limitations, internal control systems, no matter how well designed and 
operated, can provide only reasonable, not absolute, assurance that the control system's objectives 
will be met, and no evaluation of controls can provide absolute assurance that all control issues have 
been detected. The design of any system of controls is based in part on certain assumptions about the 
likelihood of future events, and there can be no assurance that any design will succeed in achieving its 
stated goals under potential future conditions, regardless of how remote. Therefore, even those 
systems determined to be effective can provide only reasonable assurance with respect to financial 
statement preparation and presentation. 
Management, including the CEO and CFO, has evaluated the effectiveness of our internal control over 
financial reporting, based on the criteria in Internal Control-Integrated Framework (2013) issued by the 
Committee of Sponsoring Organizations of the Treadway Commission. Based on this evaluation, 
management has determined that our internal control over financial reporting was effective as of 
December 31, 2024. 
During the year ended December 31, 2024, there were no changes to our internal control over 
financial reporting that materially affected, or are reasonably likely to materially affect our internal 
controls over financial reporting.
KPMG LLP ("KPMG"), our independent registered public accounting firm, has audited our annual 
financial statements and expressed an unqualified opinion thereon. KPMG has also expressed an 
unqualified opinion on the effective operation of our internal control over financial reporting as of 
December 31, 2024. KPMG's audit report on effectiveness of internal control over financial reporting is 
included in the Annual Financial Statements.

SUMMARY OF QUARTERLY RESULTS AND DISCUSSION OF THE QUARTER ENDED DECEMBER 31, 
2024
Our revenues and operating results can vary significantly from quarter to quarter depending on the 
timing of product deliveries, product mix, product launch dates, R&D project cycles, timing of related 
government funding, impairment charges, restructuring charges, stock-based compensation awards 
and foreign exchange impacts. Net income and net loss has and can vary significantly from one 
quarter to another depending on operating results, gains and losses from investing activities, 
recognition of tax benefits and other similar events..

NON-GAAP FINANCIAL MEASURES & RECONCILIATIONS
In addition to the results presented in accordance with U.S. GAAP, we used EBIT, EBITDA, Adjusted 
EBITDA, gross margin, net working capital, and other non-current liabilities (collectively, the “Non-
GAAP Measures") throughout this MD&A. We believe these non-GAAP measures provide additional 
information that is useful to stakeholders in understanding our underlying performance and trends 
through the same financial measures employed by our management. We believe that EBIT, EBITDA, 
and Adjusted EBITDA are useful to both management and investors in their analysis of our ability to 
generate liquidity by producing operating cash flow to fund working capital needs, service debt 
obligations and fund capital expenditures. Management also uses these non-GAAP measures in its 
review and evaluation of the financial performance of the Company. EBITDA is also frequently used by 
stakeholders for valuation purposes whereby EBITDA is multiplied by a factor or "EBITDA multiple" 
that is based on an observed or inferred relationship between EBITDA and market values to 
determine the approximate total enterprise value of a company. We believe these non-GAAP financial 
measures also provide additional insight to stakeholders as supplemental information to our U.S. 
GAAP results and as a basis to compare our financial performance period-over-period and to compare 
our financial performance with that of other companies. We believe that these non-GAAP financial 
measures facilitate comparisons of our core operating results from period to period and to other 
companies by, in the case of EBITDA, removing the effects of our capital structure (net interest income 
on cash deposits, interest expense on outstanding debt and debt facilities), asset base (depreciation 
and amortization) and tax consequences. Adjusted EBITDA provides this same indicator of Westport's 
EBITDA from operations and removing such effects of our capital structure, asset base and tax 
consequences, but additionally excludes any unrealized foreign exchange gains or losses, stock-based 
compensation charges and other one-time impairments and costs that are not expected to be 
repeated in order to provide greater insight into the cash flow being produced from our operating 
business, without the influence of extraneous events. Readers should be aware that non-GAAP 
measures have no standardized meaning under U.S. GAAP and accordingly may not be comparable to 
the calculation of similar measures by other companies. Non-GAAP measures are intended to provide 
additional information and should not be considered in isolation or as a substitute for measures of 
performance prepared in accordance with U.S. GAAP.

BUSINESS RISKS AND UNCERTAINTIES
An investment in our business involves risk and readers should carefully consider the risks described 
in our AIF and other filings on www.sedar.com and www.sec.gov. Our ability to generate revenue and 
profit from our technologies is dependent on a number of factors, and the risks discussed in our AIF, 
which, if they were to occur, could have a material impact on our business, financial condition, 
liquidity, results of operation or prospects. While we have attempted to identify the primary known 
risks that are material to our business, the risks and uncertainties discussed in our AIF may not be the 
only ones we face. Additional risks and uncertainties, including those that we do not know about now 
or that we currently believe are immaterial may also adversely affect our business, financial condition, 
liquidity, results of operation or prospects. A full discussion of the risks impacting our business is 
contained in the AIF for the year ended December 31, 2024 under the heading “Risk Factors” and is 
available on SEDAR at www.sedar.com.

Consolidated Financial Statements
(Expressed in thousands of United States dollars)
WESTPORT FUEL SYSTEMS INC.
For the years ended December 31, 2024 and 2023 
37

Report of Independent Registered Public Accounting Firm
To the Shareholders and Board of Directors of Westport Fuel Systems Inc.:
Opinion on the Consolidated Financial Statements
We have audited the accompanying consolidated balance sheets of Westport Fuel Systems Inc. (and subsidiaries) 
(the Company) as of December 31, 2024 and 2023, the related consolidated statements of operations and 
comprehensive loss, shareholders’ equity, and cash flows for each of the years then ended and the related notes 
(collectively, the consolidated financial statements). In our opinion, the consolidated financial statements present 
fairly, in all material respects, the financial position of the Company as of December 31, 2024 and 2023, and the 
results of its operations and its cash flows for each of the years then ended, in conformity with U.S. generally 
accepted accounting principles.
We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United 
States) (PCAOB), the Company’s internal control over financial reporting as of December 31, 2024, based on 
criteria established in Internal Control – Integrated Framework (2013) issued by the Committee of Sponsoring 
Organizations of the Treadway Commission, and our report dated March 31, 2025, expressed an unqualified 
opinion on the effectiveness of the Company’s internal control over financial reporting.
Going Concern
The accompanying consolidated financial statements have been prepared assuming that the Company will continue 
as a going concern. As discussed in Note 2 to the consolidated financial statements, the Company has suffered 
recurring losses from operations and, based on the projected capital expenditures, debt servicing obligations and 
operating requirements under the current business plan, is projecting insufficient cash flows that raise substantial 
doubt about its ability to continue as a going concern. Management's plans in regard to these matters are also 
described in Note 2. The consolidated financial statements do not include any adjustments that might result from the 
outcome of this uncertainty.
Basis for Opinion
These consolidated financial statements are the responsibility of the Company’s management. Our responsibility is 
to express an opinion on these consolidated financial statements based on our audits. We are a public accounting 
firm registered with the PCAOB and are required to be independent with respect to the Company in accordance with 
the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange 
Commission and the PCAOB.
We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan 
and perform the audit to obtain reasonable assurance about whether the consolidated financial statements are free 
of material misstatement, whether due to error or fraud. Our audits included performing procedures to assess the 
risks of material misstatement of the consolidated financial statements, whether due to error or fraud, and 
performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence 
regarding the amounts and disclosures in the consolidated financial statements. Our audits also included evaluating 
the accounting principles used and significant estimates made by management, as well as evaluating the overall 
presentation of the consolidated financial statements. We believe that our audits provide a reasonable basis for our 
opinion. 
Critical Audit Matters
The critical audit matters communicated below are matters arising from the current period audit of the consolidated 
financial statements that were communicated or required to be communicated to the audit committee and that: (1) 
relate to accounts or disclosures that are material to the consolidated financial statements and (2) involved our 
especially challenging, subjective, or complex judgments. The communication of critical audit matters does not alter 
in any way our opinion on the consolidated financial statements, taken as a whole, and we are not, by 
communicating the critical audit matters below, providing separate opinions on the critical audit matters or on the 
accounts or disclosures to which they relate.

Accounting for equity investments in HPDI Technology LP and HPDI Technology AB
As discussed in Notes 3(g) and 5 to the consolidated financial statements, on June 3, 2024, the Company entered 
into a joint venture agreement with Volvo Group (“Volvo”) and contributed certain net assets of its former HPDI 
business to a newly formed joint venture ("Cespira"), consisting of two legal entities, HPDI Technology LP and HPDI 
Technology AB, in which the Company retained a 55% non-controlling interest. The Company identified HPDI 
Technology LP and HPDI Technology AB as variable interest entities (“VIEs”) as the entities are dependent on 
funding from their owners. The Company determined that it is not the primary beneficiary of the VIEs because the 
voting rights and power to exercise control is shared equally on a 50/50 basis between the owners of the VIEs, and 
accounts for its 55% equity ownership of the VIEs as equity method investments.
We identified the assessment of the accounting for the equity method investments in HPDI Technology LP and 
HPDI Technology AB as a critical audit matter due to the judgment made by management in the determination of the 
primary beneficiary of the VIEs, in identifying the activities of the VIEs that most significantly impact their economic 
performance and in evaluating whether the Company has the ability to direct these activities. This required a high 
degree of auditor judgment and significant auditor effort.
The following are the primary procedures we performed to address this critical audit matter. We evaluated the 
design and tested the operating effectiveness of an internal control over the Company’s determination of the 
accounting for the equity investments. We assessed the Company’s accounting analysis including the determination 
of the primary beneficiary of the VIEs, the identification of the activities of the VIEs that most significantly impact 
their economic performance and the evaluation of which party has the power to direct the significant activities of the 
VIEs, for consistency with the relevant accounting standards. We read the investment agreement and underlying 
documents to gain an understanding of the terms and conditions of the agreement, including of the contractual 
rights of the Company and Volvo. We compared the relevant information in the accounting analysis to the 
investment agreement and other underlying documentation and assessed the reasonableness of the Company’s 
conclusions.
Evaluation of the fair value of the Company’s investment in Cespira
As discussed in Notes 5, 8 and 9 to the consolidated financial statements, on June 3, 2024, the Company entered 
into a joint venture agreement with Volvo and contributed net assets of $45,687, including property, plant and 
equipment with a net book value of $33,244, from its former HPDI business to Cespira. The Company 
deconsolidated the HPDI business and accounted for its investment in Cespira under the equity method. The 
Company's initial investment in Cespira of $35,621 was recognized at the fair value of the Company's 55% non-
controlling interest, which was estimated using the income approach.
We identified the evaluation of the fair value of the Company’s investment in Cespira as a critical audit matter, due 
to the magnitude of the property, plant and equipment contributed by the Company. Complex auditor judgment was 
required to evaluate the application of the methodology used to estimate the fair value of the contributed assets and 
liabilities.
The following are the primary procedures we performed to address this critical audit matter. We evaluated the 
design and tested the operating effectiveness of an internal control related to the Company’s process to determine 
the fair value of the investment in Cespira. We tested the completeness and accuracy of the underlying data used in 
the determination of the fair value of the property, plant and equipment contributed to Cespira by comparing to the 
Company’s accounting records. We involved valuation professionals with specialized skills and knowledge, who 
assisted in (1) evaluating the estimated fair value of the contributed property, plant and equipment by comparing to 
independently developed ranges of estimated replacement costs of property, plant and equipment and (2) 
evaluating the application of the methodology used to determine the fair value of the Company’s investment in 
Cespira.

Report of Independent Registered Public Accounting Firm
To the Shareholders and Board of Directors of Westport Fuel Systems, Inc.:
Opinion on Internal Control Over Financial Reporting 
We have audited Westport Fuel Systems, Inc.’s (and subsidiaries’) (the Company) internal control over financial 
reporting as of December 31, 2024, based on criteria established in Internal Control – Integrated Framework (2013) 
issued by the Committee of Sponsoring Organizations of the Treadway Commission. In our opinion, the Company 
maintained, in all material respects, effective internal control over financial reporting as of December 31, 2024, 
based on criteria established in Internal Control – Integrated Framework (2013) issued by the Committee of 
Sponsoring Organizations of the Treadway Commission.  
We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United 
States) (PCAOB), the consolidated balance sheets of the Company as of December 31, 2024 and 2023, the related 
consolidated statements of operations and comprehensive loss, shareholders’ equity, and cash flows for each of the 
years then ended, and the related notes (collectively, the consolidated financial statements), and our report dated 
March 31, 2025, expressed an unqualified opinion on those consolidated financial statements.
Basis for Opinion 
The Company’s management is responsible for maintaining effective internal control over financial reporting and for 
its assessment of the effectiveness of internal control over financial reporting, included in the accompanying 
“Management’s Discussion and Analysis – Disclosure Controls and Procedures and Internal Controls over Financial 
Reporting”. Our responsibility is to express an opinion on the Company’s internal control over financial reporting 
based on our audit. We are a public accounting firm registered with the PCAOB and are required to be independent 
with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and 
regulations of the Securities and Exchange Commission and the PCAOB.
We conducted our audit in accordance with the standards of the PCAOB. Those standards require that we plan and 
perform the audit to obtain reasonable assurance about whether effective internal control over financial reporting 
was maintained in all material respects. Our audit of internal control over financial reporting included obtaining an 
understanding of internal control over financial reporting, assessing the risk that a material weakness exists, and 
testing and evaluating the design and operating effectiveness of internal control based on the assessed risk. Our 
audit also included performing such other procedures as we considered necessary in the circumstances. We 
believe that our audit provides a reasonable basis for our opinion.
Definition and Limitations of Internal Control Over Financial Reporting 
A company’s internal control over financial reporting is a process designed to provide reasonable assurance 
regarding the reliability of financial reporting and the preparation of financial statements for external purposes in 
accordance with generally accepted accounting principles. A company’s internal control over financial reporting 
includes those policies and procedures that (1) pertain to the maintenance of records that, in reasonable detail, 
accurately and fairly reflect the transactions and dispositions of the assets of the company; (2) provide reasonable 
assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance 
with generally accepted accounting principles, and that receipts and expenditures of the company are being made 
only in accordance with authorizations of management and directors of the company; and (3) provide reasonable 
assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the company’s 
assets that could have a material effect on the financial statements.
Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. 
Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may 
become inadequate because of changes in conditions, or that the degree of compliance with the policies or 
procedures may deteriorate.

1.
Company organization and operations:
Westport Fuel Systems Inc. (the “Company”) was incorporated under the Business Corporations Act 
(Alberta) on March 20, 1995. Westport Fuel Systems Inc. is a global company focused on engineering, 
manufacturing, and supplying alternative fuel systems and components for transportation 
applications. The Company’s diverse product offerings sold under a wide range of established global 
brands enable the use of a number of alternative fuels in the transportation sector that provide 
environmental and/or economic advantages as compared to diesel, gasoline, batteries or fuel cell 
powered vehicles. The Company's fuel systems and associated components control the pressure and 
flow of these alternative fuels, including liquid petroleum gas ("LPG"), compressed natural gas ("CNG"), 
liquified natural gas ("LNG"), renewable natural gas ("RNG") or biomethane, and hydrogen. The 
Company supplies its products in approximately 70 countries through a network of distributors, 
service providers for the aftermarket and directly to original equipment manufacturers (“OEMs”) and 
Tier 1 and Tier 2 OEM suppliers. The Company’s products and services are available for passenger car 
and light-, medium- and heavy-duty commercial vehicles and off-highway applications.
2.
Liquidity and Going Concern:
For year ended December 31, 2024, the Company reported an operating loss of $24,669. The Company 
continues to sustain operating losses and to use cash to support its business activities. As at 
December 31, 2024, the Company had cash and cash equivalents of $37,646 and long-term debt of 
$33,727, net of deferred financing fees, of which $14,660 was current. In the prior year, the Company 
amended the minimum cash covenant under the term loan with Export Development Canada 
("EDC") reducing the minimum cash requirement to $15,000. If the Company's cash and cash 
equivalents fall below the minimum cash requirement, the Company may be required to repay the 
outstanding amount of the term loan, which was $6,836 at December 31, 2024.
On September 13, 2024, the Company announced an at-the-market equity offering program (the "ATM 
Program") that allows the Company to issue up to $35,000 in common shares from treasury to the 
public from time to time, at the Company's discretion and subject to regulatory requirements. As at 
December 31, 2024, no shares were issued from treasury.
In connection with preparing consolidated financial statements for each annual and interim reporting 
period, the Company is required to evaluate whether there are conditions or events, considered in 
aggregate, that raise substantial doubt about the Company’s ability to continue as a going concern 
within one year after the date the financial statements are issued. Substantial doubt exists when 
conditions and events, considered in aggregate, indicate that it is probable a company will be unable 
to meet its obligations as they become due within one year after the date the consolidated financial 
statements are issued. This evaluation initially does not take into consideration the potential 
mitigating effect of management’s plans and actions that have not been fully implemented as of the 
date the financial statements are issued. When substantial doubt exists, management evaluates 
whether the mitigating effect of its plans sufficiently alleviates substantial doubt about the Company’s 
ability to continue as a going concern. The mitigating effect of management’s plans, however, is only 
considered if both: (1) it is probable the plans will be effectively implemented within one year after the 
date the financial statements are issued; and (2) it is probable the plans, when implemented, will 
mitigate the relevant conditions or events that raise substantial doubt about the Company’s ability to 
continue as a going concern within one year after the date the financial statements are issued.
Based on the Company's projected capital expenditures, debt servicing obligations and operating 
requirements under its current business plan, management is projecting that its existing cash and 
cash equivalents will not be sufficient to fund its operations through the next twelve months from the 
date of the issuance of these consolidated financial statements. These conditions raise substantial 
doubt about the Company's ability to continue as a going concern within one year after the date 
these consolidated financial statements are issued.

Liquidity and Going Concern (continued):
Management plans to improve the Company's liquidity position by selling certain subsidiaries in 
Europe and Argentina which comprise substantially all the assets and liabilities of the Light-Duty 
segment and continue its cost reduction initiatives. On March 30, 2025, the Company entered into a 
share purchase agreement ("SPA") with a wholly-owned investment vehicle of Heliaca Investments 
Coöperatief U.A. ("Heliaca Investments"), a Netherlands based investment firm supported by 
Ramphastos Investments Management B.V. a prominent Dutch venture capital and private equity 
firm, to sell all of the issued and outstanding shares of Westport Fuel Systems Italia S.r.l. The 
transaction provides a base purchase price of $73.1 million (€67.7 million), subject to certain 
adjustments and potential earnouts of up to an estimated $6.5  million (€6.0 million) if certain 
conditions are achieved, in accordance with the terms of the SPA. If management is successful in 
closing the sale, the Company will receive sufficient cash to fund its operations for the next twelve 
months and alleviate the risk of substantial doubt identified. As of the date of issuance of these 
consolidated financial statements, management is seeking shareholder approval of the plan to 
complete the sale of these businesses to the buyer. As such, there can be no assurance that the 
Company will be successful in obtaining sufficient funding. Accordingly, management has concluded 
under the accounting standards that these plans do not alleviate the substantial doubt about the 
Company's ability to continue as a going concern.
These consolidated financial statements have been prepared on a going concern basis, which 
contemplates the realization of assets and satisfaction of liabilities in the ordinary course of business. 
The consolidated financial statements do not include any adjustments related to the recoverability 
and classification of recorded asset amounts or the amounts and classification of liabilities that may 
be necessary if the Company were unable to continue as a going concern.
3.
Significant accounting policies:
(a)
Basis of presentation:
The consolidated financial statements include the accounts of the Company and its subsidiaries. All 
intercompany balances and transactions have been eliminated on consolidation. 
These consolidated financial statements are presented in accordance with accounting principles 
generally accepted in the United States (“U.S. GAAP”). In the statement of operations and 
comprehensive loss, certain prior period figures have been adjusted to conform to current period 
presentation.
(b)
Foreign currency translation:
The Company’s functional currency is the Canadian dollar and its reporting currency for its 
consolidated financial statement presentation is the United States dollar ("U.S. Dollar"). The functional 
currencies for the Company's subsidiaries include the following: U.S. Dollar, Canadian Dollar, Euro, 
Argentina Peso, Chinese Renminbi (“RMB”), Swedish Krona, Indian Rupee and Polish Zloty. The 
Company translates assets and liabilities of non-U.S. dollar functional currency operations using the 
period end exchange rates,  shareholders’ equity balances using the weighted average of historical 
exchange rates, and revenues and expenses using the monthly average rate for the period with 
the resulting exchange differences recognized in other comprehensive loss.

Significant accounting policies (continued):
Transactions that are denominated in currencies other than the functional currencies of the 
Company’s or its subsidiaries' operations are translated at the rates in effect on the date of the 
transaction.  Foreign currency denominated monetary assets and liabilities are translated to the 
applicable functional currency  at the exchange rates in effect on the balance sheet date. Non-
monetary assets and liabilities are translated at the historical exchange rate. All foreign exchange 
gains and losses are recognized in the consolidated statements of operations, except for the 
translation gains and losses arising from available-for-sale instruments, which are recorded through 
other comprehensive loss until realized through disposal or impairment.
Except as otherwise noted, all amounts in these financial statements are presented in U.S. dollars. For 
the years presented, the Company used the following exchange rates:

Cash and cash equivalents (including restricted cash):
Cash and cash equivalents include cash on hand, term deposits, banker acceptances and guaranteed 
investment certificates with maturities of ninety days or less when acquired. Cash and cash 
equivalents at December  31, 2024 include restricted cash of $406 (2023 - $103). Restricted cash at 
December 31, 2024 and 2023 is related to cash used to secure a letter of credit.
(d)
Accounts receivable, net:
The accounts receivable balance reflects invoiced and accrued revenue and is presented net of an 
allowance for credit losses. The Company expects most of its accounts receivable balances to continue 
to come from large customers as it supplies the majority of its products and services through a 
network of distributors and OEMs and provides Delayed OEM ("DOEM") services. The Company 
establishes current expected credit losses ("CECL") for pools of assets with similar risk characteristics 
by evaluating historical levels of credit losses, current economic conditions that may affect a 
customer's ability to pay, and creditworthiness of significant customers. When specific customers are 
identified as no longer sharing the same risk profile as their current pool, they are removed from the 
pool and evaluated separately. The Company, in the normal course of business, monitors the financial 
condition of its customers and reviews the credit history of each new customer. When the Company 
becomes aware of a specific customer's inability to meet its financial obligations to the Company 
(such as in the case of bankruptcy filings or material deterioration in the customer's operating results 
or financial position, and payment experiences), the Company records a specific credit loss provision 
to reduce the customer's related accounts receivable to its estimated net realizable value. If 
circumstances related to specific customers change, the Company's estimates of the recoverability of 
accounts receivable balances could be further adjusted.

Significant accounting policies (continued):
(e)
Inventories:
The Company’s inventories consist of the Company’s fuel system products (finished goods), work-in-
progress, purchased parts and materials. Inventories are recorded at the lower of cost and net 
realizable value. Cost is determined based on the lower of weighted average cost or first in, first out. 
The cost of fuel system product inventories, assembled parts and work-in-progress includes materials, 
labour and production overhead, including depreciation. The Company records inventory write-downs 
based on an analysis of excess and obsolete inventories determined primarily by future demand 
forecasts. In addition, the Company records a liability for firm, noncancellable, and unconditional 
purchase commitments with manufacturers for quantities in excess of the Company’s future demand 
forecast consistent with its valuation of excess and obsolete inventory.
(f)
Property, plant and equipment:
Property, plant and equipment are stated at cost.  Depreciation is provided for as follows:
Assets
Basis
Rate
Buildings
Straight-line
10 years
Computer equipment and software
Straight-line
3 years
Furniture and fixtures
Straight-line
5 years
Machinery and equipment
Straight-line
5 - 10 years
Leasehold improvements
Straight-line
Shorter of lease 
term or 
estimated 
useful life
Depreciation expense on machinery and equipment used in the production and manufacturing 
process is included in cost of revenue. All other depreciation is included in depreciation and 
amortization expense in the consolidated statements of operations and comprehensive loss.
(g)
Long-term investments:
The Company accounts for investments in which it has significant influence, including variable 
interest entities ("VIEs") for which the Company is not the primary beneficiary, using the equity 
method of accounting. Under the equity method, the Company recognizes its share of income or loss 
from equity accounted investees in the statement of operations with a corresponding change in long-
term investments. Any additional capital contributions to investees are capitalized and any dividends 
paid or payable are credited against long-term investments.
The Company identified HPDI Technology LP and HPDI Technology AB as VIEs, as the entities are 
dependent on funding from their owners. The funding and ownership interests of the entities are split 
on a 55/45 basis between the owners of the VIEs. The voting rights and power to exercise control is 
shared equally on a 50/50 basis between the owners of the VIEs. Therefore, the Company has 
determined that it is not the primary beneficiary of the VIEs. The Company's maximum exposure to 
loss are its investments in HPDI Technology LP and HPDI Technology AB and the current outstanding 
accounts receivables balances.

3.
Significant accounting policies (continued):
(h)
Financial liabilities:
Accounts payable and accrued liabilities, short-term debt, long-term debt and long-term royalty 
payable are measured at amortized cost. Transaction costs relating to long-term debt are netted 
against long-term debt and are amortized using the effective interest rate method.
(i)
Research and development costs:
Research and development costs are expensed as incurred and are recorded net of funding received 
or receivable.
(j)
Intangible assets:
Intangible assets consist primarily of the estimated value of intellectual property, trademarks, 
technology, customer contracts and non-compete agreements acquired through acquisitions. 
Intangible assets are amortized over their estimated useful lives, which range from 5 to 20 years.
(k)
Impairment of long-lived assets:
The Company reviews its long-lived assets for impairment whenever events or changes in 
circumstances indicate that the carrying amount of the assets may not be recoverable. If such 
conditions exist, assets are considered impaired if the sum of the undiscounted expected future cash 
flows expected to result from the use and eventual disposition of an asset is less than its carrying 
amount. An impairment loss is measured at the amount by which the carrying amount of the asset 
exceeds its fair value. When quoted market prices are not available, the Company uses the expected 
future cash flows discounted at a rate commensurate with the risks associated with the recovery of 
the asset as an estimate of fair value.
(l)
Goodwill:
Goodwill is recorded at the time of purchase for the excess of the amount of the purchase price over 
the fair values of the identifiable assets acquired and liabilities assumed. The fair value is determined 
using the estimated discounted future cash flows of the reporting unit. Goodwill is not amortized and 
instead is tested at least annually for impairment, or more frequently when events or changes in 
circumstances indicate that goodwill might be impaired. This impairment test is performed annually 
at December 31. Future adverse changes in market conditions or poor operating results of underlying 
assets could result in an inability to recover the carrying value of the goodwill, thereby possibly 
requiring an impairment charge.

Significant accounting policies (continued):
(m)
Warranty liability:
Estimated warranty costs are recognized at the time the Company sells its products and are included 
in cost of revenue. The Company provides warranty coverage on products sold from the date the 
products are put into service by customers. Warranty liability represents the Company’s best estimate 
of warranty costs expected to be incurred during the warranty period.   Furthermore, the current 
portion of warranty liability represents the Company’s best estimate of the costs to be incurred in the 
next twelve-month period.  The Company uses historical failure rates and costs to repair defective 
products to estimate the warranty liability. New product launches require a greater use of judgment 
in developing estimates until claims experience becomes available. Product specific experience is 
typically available four or five quarters after product launch, with a clear experience trend not evident 
until eight to twelve quarters after launch. The Company records warranty expense for new products 
using historical experience from previous generations in the first year, a blend of actual product and 
historical experience in the second year and product specific experience thereafter.  The amount 
payable by the Company and the timing will depend on actual failure rates and cost to repair failures 
of its products. 
(n)
Revenue recognition:
The Company generates revenues primarily from product sales. Product revenues are derived from 
standard product sales contracts and from long-term fixed price contracts. The Company recognizes 
revenue when a customer obtains control of the goods. Determining the timing of the transfer of 
control, at a point in time or over time, requires judgment. On standard product sales contracts, 
revenues are recognized when customers obtain control of the product, that is when transfer of title 
and risks and rewards of ownership of goods have passed and when obligation to pay is considered 
certain. Invoices are generated and revenue is recognized at that point in time. Provisions for 
warranties are made at the time of sale. Service revenue is recognized over time as performance 
obligations are satisfied.
(o)
Income taxes:
The Company accounts for income taxes using the asset and liability method. Under this method, 
deferred income tax assets and liabilities are determined based on the temporary differences 
between the accounting basis and tax basis of the assets and liabilities and for loss carry-forwards, tax 
credits and other tax attributes, using the enacted tax rates in effect for the years in which the 
differences are expected to reverse. The effect of a change in tax rates on deferred income tax assets 
and liabilities is recognized in income in the period that includes the enactment date.  
The Company recognizes deferred income tax assets to the extent the assets are more-likely-than-not 
to be realized. In making such a determination, the Company considers all available positive and 
negative evidence including future reversals of existing taxable temporary differences, projected 
future taxable income, tax-planning strategies and results of recent operations. If it is determined that, 
based on all available evidence, it is more-likely-than-not that some or all of the deferred income tax 
assets will not be realized, a valuation allowance is provided to reduce the deferred income tax assets.

3.
Significant accounting policies (continued):
The Company uses a two-step process to recognize and measure the income tax benefit of uncertain 
tax positions taken or expected to be taken in a tax return.  The tax benefit from an uncertain tax 
position is recognized if it is more-likely-than-not that the position will be sustained upon examination 
by a tax authority based solely on the technical merits of the position. A tax benefit that meets the 
more-likely-than-not recognition threshold is measured as the largest amount that is greater than 
50% likely to be realized upon settlement with the tax authority. To the extent a full benefit is not 
expected to be realized, an income tax liability is established. Any change in judgment related to the 
expected resolution of an uncertain tax position is recognized in the year of such a change. 
Interest and penalties related to income taxes are included as a component of income tax expense.
(p)
Leases:
The Company determines if an arrangement is a lease or contains a lease at inception. Operating 
leases with lease terms greater than 12 months are included in current and non-current assets, 
current and non-current liabilities in the consolidated balance sheet. Assets under finance leases are 
included in property, plant and equipment and the related lease liabilities in current  and non-current 
liabilities in the consolidated balance sheets.
Operating lease and finance lease right-of-use (“ROU”) assets and operating lease liabilities are 
recognized based on the present value of the future lease payments over the lease term at the 
commencement date. As the rate implicit in the lease is not readily determinable for the Company’s 
operating leases, an incremental borrowing rate is generally used to determine the present value of 
future lease payments. The incremental borrowing rate for each lease is based on the Company’s 
estimated borrowing rate over a similar term to that of the lease payments, adjusted for various 
factors including collateralization, location and currency.
The operating lease expenses are recognized on a straight-line basis over the lease term and included 
in cost of revenue and operating expenses. Short-term leases, which have an initial term of 12 months 
or less, are not recorded in the consolidated balance sheets.
(q)
Stock-based compensation:
The Company measures stock-based awards at fair value on the date of the grant and expense the 
awards over the requisite service period of employees or consultants. The fair value of stock options is 
determined using the fair market value at the time of grant. The fair value of restricted stock units 
(“RSUs") and Deferred Share Units (“DSUs") are determined using the share price of the Company at 
the date of grant. The fair value of performance based restricted stock units (“PSUs”) is determined 
using the Monte Carlo Simulation Model. Stock-based compensation expense related to stock option 
awards is recognized over the requisite service period on a graded vesting basis. Forfeitures are 
accounted for as they occur. Stock-based awards are either equity settled or cash settled. Cash-settled 
awards are recorded as a liability based on the Company's share price on the date of grant and 
remeasured at the end of each reporting period over the vesting term.
The Company’s estimates may be impacted by certain variables including, but not limited to, stock 
price volatility, employee stock option exercise behaviors, additional stock option grants, the 
Company’s performance and related tax impacts.

Significant accounting policies (continued):
(r)
Earnings (loss) per common share:
Basic earnings or loss per share includes no potential dilution and is computed by dividing the 
earnings or loss attributable to common stockholders by the weighted average number of common 
shares outstanding for the period. Diluted earnings or loss per share reflect the potential dilution of 
securities that could share in the earnings or loss of our Company. Dilutive securities are excluded 
from the calculation of our diluted weighted average common shares outstanding if their effect 
would be anti-dilutive based on the treasury stock method or due to a net loss from continuing 
operations. Common Shares that have not been released under the Company’s  stock based plan or 
are being held in trust for purposes of the Company’s restricted stock unit program have been 
excluded from the calculation of basic earnings per share.
(s)
Contingent consideration:
The Company may enter into contingent consideration arrangements whereby a buyer pays the seller 
additional consideration after transaction close upon the achievement of certain milestones, 
performance-based metrics, or other objectives as agreed to per the terms of the related agreement.
The Company elected to account for contingent considerations that are not identified as derivatives 
using the loss recovery approach. The Company does not recognize any contingent receivable at 
inception and will recognize a contingent gain when such gain is realized or realizable.
4.
New accounting pronouncements
New accounting standard adopted in 2024:
In November 2023, the Financial Accounting Standards Board ("FASB") issued Accounting Standards 
Update ("ASU") 2023-07, "Segment Reporting (Topic 280): Improvements to Reportable Segment 
Disclosures." It requires incremental disclosures related to an entity's reportable segments, including:
(i) significant segment expense categories and amounts for each reportable segment that are
provided to the Chief Operating Decision Maker ("CODM"),
(ii) an aggregate amount and description of other segment items included in each reported
measure,
(iii) all annual disclosures about a reportable segment's profit or loss and assets required by
Topic 280 to be disclosed in interim periods,
(iv) the title and position of the individual or name of the group identified as the CODM, and
(v) an explanation of how the CODM uses the reported measures of segment profit or loss to
assess performance and allocate resources to the segment.
The standard improves transparency by providing disaggregated expense information about an 
entity's reportable segments. The standard does not change the definition of a segment, the method 
for determining segments or the criteria for aggregating operating segments into reportable 
segments. The Company has adopted this guidance in the current year reported and recast the 
comparative disclosures as required. Refer to Note 22 "Segment Information" of the consolidated 
financial statements for more information.

New accounting pronouncements (continued):
Upcoming accounting standards not yet adopted in 2024:
In December 2023, the FASB issued ASU 2023-09, "Income Taxes (Topic 740): Improvements in Income 
Tax Disclosures" to enhance the transparency and decision usefulness of income tax disclosures. This 
amendment requires public companies to disclose specific categories in the rate reconciliation and 
provide additional information for reconciling items that meet a quantitative threshold. Additionally, 
under the amendment entities are required to disclose the amount of income taxes paid 
disaggregated by federal, state and foreign taxes, as well as disaggregated by material individual 
jurisdictions. Finally, the amendment requires entities to disclose income from continuing operations 
before income tax expense disaggregated between domestic and foreign and income tax expense 
from continuing operations disaggregated by federal, state and foreign. This guidance is effective for 
annual reporting periods beginning after December 15, 2024. While this guidance may have an impact 
on the disclosures, the Company does not expect this guidance to have a material impact on its 
financial position, operations, and cash flows.
In November 2024, the FASB issued ASU 2024-03, "Income Statement - Reporting Comprehensive 
Income - Expense Disaggregation Disclosures (Subtopic 220-40): Disaggregation of Income 
Statement Expenses." It requires entities to disclose, in the notes to the financial statements, specified 
information related to certain costs and expenses disaggregated by type. The standard improves 
transparency by providing more detailed information about the component of costs and expenses 
that would enable users to better understand the major components of an entity's income statement 
by referencing disclosures in the notes to financial statements. This guidance is effective for annual 
reporting periods beginning after December 15, 2026. While this guidance may have an impact on the 
disclosures, the Company does not expect this guidance to have a material impact on its  financial 
position, operations, and cash flows.

Formation of joint venture
Cespira
On June 3, 2024, the Company entered into a joint venture agreement with Volvo Group ("Volvo") and 
contributed certain net assets of its former HPDI business to a newly formed joint venture ("Cespira" 
formerly the "HPDI Joint Venture"), consisting of two legal entities, HPDI Technology LP and HPDI 
Technology AB, in which the Company retained a 55% non-controlling interest. Volvo acquired the 
remaining 45% interest in Cespira for cash consideration of $27,328 plus up to an additional $45,000 in 
contingent consideration, or earnout, depending on the subsequent performance of the joint venture. 
The Company did not recognize any contingent consideration receivable at inception. Cespira is 
jointly controlled by both parties. The Company's former HPDI business continues to operate through 
the joint venture.
The Company deconsolidated the HPDI business and accounted for the Company's investment in 
Cespira under the equity method as it is now jointly controlled. Under this accounting method, the 
Company's initial investment in Cespira was recognized at the fair value of the Company's non-
controlling interest. The Company used the income approach to estimate the fair value of the 
Company's non-controlling interest in Cespira of $35,621. Subsequently, this cost basis will be adjusted 
for the Company's share of Cespira's net income or loss and other comprehensive income or loss, net 
of any dividends or distributions received from Cespira.
This table summarizes the fair values of the proceeds received, net assets transferred at carrying value 
to Cespira, estimated liabilities including working capital adjustment payment owed to Volvo and 
indirect taxes incurred in certain jurisdictions for the fixed assets transferred, and gain on 
deconsolidation:

In 2022, a holdback receivable was recorded as part of the sale of the Company's interest in Cummins 
Westport Inc. to Cummins Inc. ("Cummins"). The holdback will be retained by Cummins for a term of 
three years to satisfy any extended warranty obligations in excess of the recorded extended warranty 
obligation. Any unused amounts will be repaid to the Company at the end of three years term and, in 
the event that the holdback is not sufficient to cover the extended warranty obligations, the Company 
may also be required to supplement this holdback amount to cover valid extended warranty claims. In 
March 2025, the Company collected $11,365 from Cummins related to the holdback receivable, 
including interest accrued.

HPDI Technology ("Cespira"):
The Company entered into a joint venture agreement with Volvo Group ("Volvo") and contributed 
certain net assets of its former HPDI business to a newly formed joint venture ("Cespira" formerly the 
"HPDI Joint Venture"), consisting of two legal entities, HPDI Technology LP and HPDI Technology AB, 
in which the Company retained a 55% non-controlling interest. Volvo acquired the remaining 45% 
interest in Cespira for cash consideration of $27,328. Cespira is jointly controlled by both parties. The

an initial capital contribution of $9,900 in Cespira to fund its operations. For the year ended 
December  31, 2024, the Company recognized its share of Cespira’s losses of $6,715, as a loss from 
investments accounted for by the equity method.
The Company acknowledges that during the initial phase of Cespira's business plan, it may require 
additional funding from its owners from time to time. If either owner is unable to fund Cespira when 
funding is requested in accordance with the joint venture agreement, a convertible loan may be 
extended from the other owner to fund all or a part of the funding requested. The convertible loan 
may settle in ownership interest in Cespira in the event that the borrowing party is unable to fulfill the 
repayment terms.

Long-term investments (continued):
(b)
Weichai Westport Inc. ("WWI"):
The Company, indirectly through its wholly-owned subsidiary, Westport Innovations (Hong Kong) 
Limited (“Westport HK”), was the registered holder of a 23.33% equity interest in Weichai Westport Inc. 
("WWI"). In April 2016, the Company sold to Cartesian Capital Group (“Cartesian”) a derivative economic 
interest granting it the right to receive an amount of future income received by Westport HK from 
WWI equivalent to having an 18.78% equity interest in WWI and concurrently granted a Cartesian 
entity an option to acquire all of the equity securities of Westport HK for a nominal amount. The 
Company retained the right to transfer any equity interest held by Westport HK in WWI that was in 
excess of an 18.78% interest in the event that such option was exercised. As a result of such 
transactions, the Company’s residual 23.33% equity interest in WWI currently corresponds to an 
economic interest in WWI equivalent to 4.55%.
On July 8, 2024, the Company sold its remaining interest in WWI to Weichai Holding Group Co. Ltd 
("Weichai") for net proceeds of $1,124 and recognized a loss on sale of investment of $352. This sale was 
pursuant to an equity transfer agreement signed with WWI in December 2023. The Company 
previously recognized a related impairment loss of $413 for the year ended December 31, 2023.
(c)
Minda Westport Technologies Limited ("MWTL"):
The Company, indirectly through its wholly owned subsidiary, Westport Fuel Systems Italia S.R.L., was

an amended and restated joint venture agreement with Uno Minda Limited ("Minda"). 
On April 18, 2024, the Company completed a share purchase agreement with Uno Minda Limited 
("Minda") and sold 26% of MWTL's shares to Minda for net proceeds of $1,542. As at December 31, 2024, 
the Company has assessed the carrying amount to be equal to the fair value of the investment.
For the year ended December 31, 2024, the Company recognized its share of MWTL's earnings of $1,313 
(2023 - $780) as income from investments accounted for by the equity method and received a 
dividend of $297.

Operating leases right-of-use assets and lease liabilities:
The Company has entered into various non-cancellable operating lease agreements primarily for its 
manufacturing facilities and offices. The Company's leases have lease terms expiring between 2025

renewals in its determination of the lease term unless the renewals are deemed to be reasonably 
assured at lease commencement. The average remaining lease term is approximately six years and 
the present value of the outstanding operating lease liability was determined by applying a weighted 
average discount rate of 3.0% based on incremental borrowing rates applicable in each location.

Long-term debt (continued):
On December 13, 2021, the credit facility and non-revolving term facility with EDC were refinanced into 
one $20,000 term loan, with quarterly principal and interest payments. On May 31, 2024, the Company 
amended the loan agreement with EDC to permit the asset transfer of certain property, plant, and 
equipment previously pledged to the loan into Cespira, removal of Fuel System Solutions Inc. as a 
borrower, added Westport Fuel Systems Canada Inc. as a borrower and modified the securities 
pledged to the loan. The loan is secured by share pledges in the Company's equity interest in Cespira.
On May 20, 2020, and July 17, 2020, the Company entered into two Euro denominated loan 
agreements with UniCredit. There are no securities provided on the loans as the loans were made as

government’s COVID-19 Decreto Liquidità.
On October 9, 2018, and November 28, 2019, the Company entered into two Euro denominated loan 
agreements with UniCredit S.p.A. (“UniCredit”). On April 29, 2021, the Company and UniCredit

Share Units ("Units"):
The value assigned to issued Units and the amounts accrued are recorded as other equity 
instruments. As Units are exercised or vested and the underlying shares are issued from treasury of 
the Company, the value is reclassified to share capital.
During the year ended December 31, 2024, the Company recognized $1,357 (year ended December 31, 
2023 - $1,727) of stock-based compensation associated with the Westport Omnibus Plan. The 
Westport Omnibus Plan aims to advance the Company's interests by encouraging employees, 
consultants and non-employee directors to receive equity-based compensation and incentives. The 
plan outlines the stock-based options types, eligibility and vesting terms.

During the year ended December 31, 2024, 224,050 share units were granted to directors, executives 
and employees (year ended December 31, 2023 - 435,128). This included 104,215 Restricted Share Units 
("RSUs") (year ended December  31, 2023 - 147,557) and nil Performance Share Units ("PSUs") (year 
ended December  31, 2023 - 185,365) and 119,835 Deferred Share Units ("DSUs") (year ended 
December 31, 2023 - 102,206 DSUs) to be cash-settled when vesting conditions are met.
Values of PSUs are determined using the Monte–Carlo Simulation Model. RSUs typically vest over a 
three-year period so the actual value received by the individual depends on the share price on the day 
such RSUs are settled for common shares, not the date of grant. Vesting of DSUs shall occur 
immediately prior to the resignation, retirement or termination of directorship, in accordance with the 
terms of Westport's Omnibus Plan.
As at December 31, 2024, $950 of compensation expense related to Units has yet to be recognized in 
results from operations and will be recognized ratably over one year.

Income taxes (continued):
The valuation allowance is reviewed on a quarterly basis to determine if, based on all available 
evidence, it is more-likely-than-not that some or all of the deferred income tax assets will not be 
realized. The ultimate realization of deferred income tax assets is dependent on the generation of 
sufficient taxable income during the future periods in which those temporary differences are 
expected to reverse. If the evidence does not exist that the deferred income tax assets will be fully 
realized, a valuation allowance has been provided. The deferred income tax assets have been reduced 
by the uncertain tax position presented in note 19(f).

Commitments and contingencies:
(a)
Contractual commitments
The Company is a party to a variety of agreements in the ordinary course of business under which it is 
obligated to indemnify a third party with respect to certain matters. Typically, these obligations arise 
as a result of contracts for sale of the Company’s product to customers where the Company provides 
indemnification against losses arising from matters such as product liabilities. The potential impact on 
the Company’s financial results is not subject to reasonable estimation because considerable 
uncertainty exists as to whether claims will be made and the final outcome of potential claims. To 
date, the Company has not incurred significant costs related to these types of indemnifications.
(b)
Contingencies
The Company is engaged in certain legal actions and tax audits in the ordinary course of business and 
believes that, based on the information currently available, the ultimate outcome of these actions will 
not have a material adverse effect on our operating results, liquidity or financial position.
22.
Segment information:
The Company discloses segment information under four reportable segments, consistent with the 
manner in which its Chief Operating Decision Maker ("CODM") evaluates its businesses. The 
Company's CODM is its Chief Executive Officer. These segments are the strategic pillars of the 
Company and are managed separately as each represents a specific grouping of related automotive 
components and systems.  The reportable segments are further described below. In prior years, the 
Company presented its results under two reportable segments: Independent aftermarket and 
Original equipment manufacturer. 
Effective June 3, 2024, the Company changed how it evaluates and manages its businesses as a result 
of the deconsolidation of its former HPDI business and formation of the joint venture (note 5). The 
Company now reports its results in the following four reportable segments: Light-Duty, High-Pressure 
Controls & Systems, Heavy-Duty OEM, and Cespira. The prior year comparatives were recast to reflect 
this change in reportable segments.
•
Light-Duty: This segment's products include LPG and CNG fuel system solutions and
components including fuel storage tanks and electronic control modules.
•
High-Pressure Controls and Systems: This segment's products include fuel cell and hydrogen
fuel system solutions and components.
•
Heavy-Duty OEM: Prior to June 3, 2024, this segment's products include HPDI related fuel
system solutions and components. Subsequently, this segment's operations are related to the
transitional services agreement between the Company and Cespira.
•
Cespira: This segment's products include HPDI related fuel system solutions and components
after June 3, 2024.

Segment information (continued):
Segment earnings or losses before income taxes, interest, depreciation, and amortization ("Segment 
EBITDA") is the measure of segment profitability used by the Company. The accounting policies of our 
reportable segments are the same as those applied in our consolidated financial statements. 
Management prepared the financial results of the Company's reportable segments on basis that is 
consistent with the manner in which Management internally disaggregates financial information to 
assist in making internal operating decisions. Certain common costs and expenses were allocated 
among segments and presented differently than the Company would for stand-alone financial 
information prepared in accordance with GAAP. These include certain costs and expenses of shared 
services, such as IT, human resources, legal, finance and supply chain management. Segment EBITDA 
is not defined under US GAAP and may not be comparable to similarly titled measures used by other 
companies and should not be considered a substitute for net earnings or other results reported in 
accordance with GAAP.
The Company's CODM uses segment EBITDA disclosed below to evaluate the performance of its 
reportable segments. The Company believes Segment EBITDA is most reflective of the operational 
profitability or loss of its reportable segments. The CODM uses this information to drive decisions and 
resource allocations. Segment EBITDA is used as the key profitability measure when we set our annual 
budget.

Financial instruments (continued):
Credit risk
Credit risk arises from the potential that a counterparty to a financial instrument fails to meet its 
contractual obligations and arises principally from the Company’s accounts receivable.
The Company is exposed to credit risk with respect to uncertainties as to timing and amount of 
collectability of accounts receivable. As at December  31, 2024, 65% (December  31, 2023 - 88%) of 
accounts receivable relate to customer receivables, and 35% (December  31, 2023 - 12%) relates to 
amounts due from related parties and income tax authorities for value added taxes and other tax 
related refunds. In order to minimize the risk of loss for customer receivables, the Company’s 
extension of credit to customers involves review and approval by senior management as well as 
progress payments as contracts are executed. Most sales are invoiced with payment terms in the 
range of 30 days to 90 days. Refer to note 3(d) for the Company's policy with respect to an allowance 
for credit losses.
Foreign currency risk
Foreign currency risk is the risk that the fair value of future cash flows of financial instruments will 
fluctuate because of changes in foreign currency exchange rates. The Company conducts a significant 
portion of its business activities in foreign currencies, primarily the U.S. dollar and the Euro. The 
Company are subject to foreign currency exchange rate risk to the extent that our costs are 
denominated in currencies other than those in which the Company earn revenues. In addition, since 
the Company's consolidated financial statements are reported in U.S. dollars, changes in foreign 
currency exchange rates between the U.S. dollar and other currencies have had, and will continue to 
have, an impact on the Company's results of operations, financial condition and cash flows. 
Cash and cash equivalents, accounts receivable, accounts payable, and long-term debt that are 
denominated in foreign currencies will be affected by changes in the exchange rate between the 
Canadian dollar and these foreign currencies.  The Company’s functional currency is the Canadian 
dollar.
A 5% increase/decrease in the relative value of the U.S. dollar against the Canadian dollar and Euro 
compared to the exchange rates in effect for the year ended December 31, 2024 would have resulted 
in lower/higher income from operations of approximately $1,200. This assumes a consistent 5% 
appreciation in the U.S. dollar against the Canadian dollar and the Euro throughout the fiscal year. The 
timing of changes in the relative value of the U.S. dollar can affect the magnitude of the impact that 
fluctuations in foreign exchange rates have on our income from operations.
Interest rate risk
Interest rate risk is the risk that the fair value of future cash flows of a financial instrument will 
fluctuate because of changes in market interest rates. The Company is subject to interest rate risk on 
certain long-term debt with variable rates of interest. The Company limits its exposure to interest rate 
risk by entering into interest rate swaps that serve as a hedging mechanism against potential 
fluctuations in future interest rates on certain financial instruments and continually monitoring and 
adjusting portfolio duration to align to forecasted cash requirements and anticipated changes in 
interest rates. 
If interest rates for the year ended December 31, 2024 had increased or decreased by 200 basis points, 
with all other variables held constant, net loss for the year ended December  31, 2024 would have 
increased or decreased by $305.

Financial instruments (continued):
Fair value of financial instruments
As at December 31, 2024, cash and cash equivalents are measured at fair value on a recurring basis 
and are included in Level 1.
The carrying amounts reported in the consolidated balance sheets for cash and cash equivalents, 
accounts receivable, accounts payable and accrued liabilities approximate their fair values due to the 
short-term period to maturity of these instruments.
The long-term investments represent the Company's interests in Cespira, MWTL, and other 
investments. Cespira and MWTL are accounted for using the equity method. Other investments are 
accounted for at fair value.
The carrying values reported in the consolidated balance sheets for obligations under capital and 
operating leases, which are based upon discounted cash flows, approximate their fair values.
The carrying values of the term loan facilities, and other bank financing included in the long-term 
debt (note 16) are carried at amortized costs, which approximate their respective fair values as at 
December 31, 2024. The interest rate swaps (note 16) are accounted for at fair value using the quoted 
market prices.
The Company categorizes its fair value measurements for items measured at fair value on a recurring 
basis into three categories as follows:
Level 1 –
Unadjusted quoted prices in active markets for identical assets or liabilities.
Level 2 –
Observable inputs other than Level 1 prices such as quoted prices for similar assets 
or liabilities; quoted prices in markets that are not active; or other inputs that are 
observable or can be corroborated by observable market data for substantially the 
full term of the assets or liabilities.
Level 3 –
Inputs for the asset or liability that are not based on observable market data 
(unobservable inputs).
When available, the Company uses quoted market prices to determine fair value and classify such 
items in Level 1. When necessary, Level 2 valuations are performed based on quoted market prices for 
similar instruments in active markets and/or model–derived valuations with inputs that are observable 
in active markets. Level 3 valuations are undertaken in the absence of reliable Level 1 or Level 2 
information.
