Westport reports fourth fiscal quarter and year end results for March 31, 2003

VANCOUVER, June 3 -- Westport Innovations Inc. (WPT:TSE) today reported results for its fourth quarter and fiscal year ended March 31, 2003. Westport also reviewed milestones achieved during the past year and provided an update on strategy, business plans, and operations. Full quarterly and annual statements including notes are posted on the Westport website, www.westport.com, along with the Management Discussion and Analysis of the annual results.

The financial results for fiscal 2003 met or exceeded management's guidance as discussed in December, 2002.

Westport saw strong sales growth as total revenue rose to $8.3 million for the fourth quarter, compared to $7.2 million for the same quarter last year and $5.6 million in the third quarter. The revenue growth was driven by an increase in engine shipments to 321 units for the fourth quarter, compared to 198 units for the same quarter last year, as well as parts revenue, which grew to $0.8 million from $0.4 million for the same quarter last year. For the full year, total revenue was $24.6 million for fiscal 2003, down from $31.4 in 2002. The decrease in revenue for the year was attributable to a decrease in engine shipments in 2003 to 884 units from 1,161 in 2002, primarily as a result of lower demand for natural gas engines in the North American transit market.

Gross margins grew to $8.0 million for 2003 from $7.5 million for 2002 as a result of the large increase in parts revenue, offsetting the decrease in engine shipments on an annual basis. Gross margins also increased on a quarterly basis to $2.3 million for the fourth quarter of 2003, from $1.9 million in the same quarter last year.

Research and development, the largest expense category, decreased on both a quarterly and annual basis as a result of significantly improved program funding. Net R&D spending for the fourth quarter of 2003 was $7.4 million, down from $8.8 million in the same quarter last year and $37.3 million for the full 2003 year, down from $38.6 million for 2002. Program funding from government and industry sources was $7.0 million for the fourth quarter of 2003, up from $0.1 million in the same quarter last year, and $8.0 million for the full 2003 year, up from $1.5 million for 2002. The largest funding source in 2003 was Technology Partnerships Canada (TPC), which contributed $5.6 million in the first year of a three-year $18.9 million program.

In order to focus and strengthen its operations going forward and reduce its overall cash requirements, Westport recently announced and undertook a restructuring of its business activities. As a result of these actions, a charge of $1.4 million was accrued in the fourth quarter of 2003, of which $0.5 million was a non-cash expense.

The net loss was $11.3 million or $0.22 per share for the fourth quarter compared with $11.7 million or $0.25 per share a year earlier. For the full fiscal year ended March 31, 2003, the loss was $48.5 million or $0.95 per share compared with $46.7 million or $1.06 per share a year earlier. Excluding restructuring charges of $1.4 million, the loss per share was $0.19 in the quarter and $0.93 for the year.

At March 31, 2003, cash, cash equivalents and short-term investments totaled $28.1 million. In addition, $5.6 million due from the Canadian Government's Technology Partnership Canada Program (TPC) was included in accounts receivable at year end.

"2003 was an important transition year for Westport," said David Demers, Westport's President and Chief Executive Officer. "The company has established a strong presence in new markets such as Asia and Europe, we developed strong alliances and relationships that will help us build our business, and we assembled a top notch operational management team that is committed to delivering our business plan. During the year we launched a number of important new products, and established ourselves in the emerging technology of hydrogen combustion engines. Despite the tough economic climate, we grew our gross margin line year over year, and managed our cash to meet guidance. We are confident that we have built the foundation for a strong, global business."

Review of Fourth Quarter

Westport made significant progress towards its commercialization goals during the fourth quarter. The achievements include the second highest quarterly revenues in the company's history, significant expansion by Cummins Westport Inc. (CWI) into new global markets, major funding from governments for both technology development and market demonstration of products, enhancing our relationships with partners, and implementing the transition plan developed during the quarter that will drive the company to sharper business focus and operational success as we transition from a development company to a growing commercial business.

CWI improved market share and received important orders for the C Gas Plus engine for bus fleets in the U.S. In Asia, CWI started the quarter with a market presence in only one city and by the end of the quarter CWI had expanded into six additional cities. The North American launch of the B LPG Plus propane engine occurred shortly after the end of the quarter. It joins the family of natural gas engines, including the B Gas Plus engine, the C Gas Plus engine, and the B5.9G engine.

Governments and industry continued to recognize the clean air value of natural gas engines through technology development programs during the quarter. For example, CWI was awarded $760,000 to test and demonstrate catalyzed particulate controls on its natural gas engines. These controls have the potential to dramatically reduce particulate matter, a leading cause of health concerns related to diesel engines, to almost undetectable levels in natural gas engines. CWI also received $770,000 related to Hythane (a natural gas and hydrogen blend) engine testing in Vancouver and at Sunline Transit in Thousand Palms, CA from the U.S. Department of Energy's National Renewable Energy Laboratory and California's South Coast Air Quality Management District.

At the end of the quarter, Westport was awarded a strategic project investment of $18.9 million from Technology Partnerships Canada to support the development of low-emissions, natural gas and hydrogen engines for vehicular applications over the next several years. This investment will enable the Company to maintain technology leadership in the development of clean gaseous- fueled engines.

Westport continued building its relationship with MAN Nutzfahrzeuge AG, one of the largest heavy-duty truck and bus manufacturers in Europe. In February, we completed testing of a MAN 12-liter truck engine equipped with our proprietary high-pressure direct-injection natural gas system. This engine was shipped to MAN's Nurnberg, Germany facility to start the next stage of testing, which is expected to be completed by the third quarter of fiscal 2004. The German gas industry, led by RuhrGas AG, has provided funding to offset Westport's development during this phase. In addition, to prioritize commercial opportunities for these vehicles, MAN, Westport and the German gas industry are commissioning an independent market study. This is an important step forward that will lead to establishing a broader relationship with MAN.

Westport's technology development program with Isuzu Motors Ltd. is also progressing on schedule, with significant technical progress made during fiscal 2003. This has progressed to a planned intense testing regime in the first half of fiscal 2004 leading to a light-duty delivery truck, equipped with Westport's high pressure, direct injection technology, being commissioned by Isuzu in the third quarter of fiscal 2004. Following that delivery, Isuzu and Westport will conduct engine testing along with an evaluation of market opportunities for low-emissions trucks using Westport's technology in Japan.

CWI continued to advance its new engine programs during the quarter. The B LPG Plus propane engine commercially launched as scheduled in May 2003. The ISX G (400 horsepower) engine for heavy-duty trucks is continuing its field trials at Norcal with over 1.8 million miles clocked on the 14 trucks in service over the past sixteen months of field-testing. The next version of the engine with cooled exhaust gas recirculation is being readied for testing at Norcal in the third quarter of fiscal 2004. This final phase of field-testing will lead to the commercial product launch in the first quarter of fiscal 2005 with a 450 horsepower version of the ISX G engine being launched about six months following. The L Gas Plus engine is also planned to commence field trials by the end of December 2003 with commercial launch planned by mid-2004.

During the quarter, the next generation technology for the 60-liter QSK engine was installed on field-trial power generation units operating in Anaheim, California and Grande Prairie, Alberta. Significant improvements in emissions performance, power density and reliability are incorporated into this new generation. Despite the significant technical progress and the emerging market opportunities, commercial launch of a product incorporating this technology will depend on the availability of development funding.

  Review of Fiscal 2003 Milestones

  Westport's 2002 annual report set out management's goals for the fiscal
  year ending March 31, 2003. Management's assessment of the year follows:

  - We did not meet our revenue growth target; growth in new markets was
    slower than anticipated and our core market, North American natural gas
    transit engines, shrank substantially from the previous year. However,
    in this tough environment we were able to improve both our market share
    and gross margin.

  - The loss per share goal was met.

  - The ISX G engine is expected to be certified with emissions
    significantly below the 2002 U.S. EPA regulatory limits. As discussed
    during the year, the launch date for the 400 horsepower version of this
    engine will be in 2004 to allow for the appropriate testing and launch
    of the cooled exhaust gas recirculation version of this engine.

  - Our cooperative development agreements with both MAN and Isuzu have
    gone well this year, and a new program with BMW was announced and
    completed. However, our relationship with Ford did not move forward to
    a commercial vehicle program because of budgetary constraints at Ford.

  - During the year a number of important new industry and government
    alliances were developed and expanded, including Westport becoming a
    founding partner in the California Natural Gas Vehicle Partnership.
    Funding projects were initiated with Sustainable Development Technology
    Canada, the U.S. National Renewable Energy Laboratory, Brookhaven
    National Laboratory, California's South Coast Air Quality Management
    District, the California Air Resources Board, the U.S. Propane
    Education & Research Council, the Canadian International Development
    Agency, and WestStart-CALSTART, a California-based non-profit
    consortium developing advanced transportation technologies. The
    Government of Canada invested $18.9 million through the Technology
    Partnerships Canada program. Overall, financial support from government
    increased tenfold during the year.

  - Both Asian and European markets were entered successfully. In Europe,
    Westport has completed the acquisition of GVH and is now operating from
    research facilities in Dortmund, Germany; Cummins Westport business
    leaders are in place for Europe and Asia as well as North America.
    Sales were made for the first time in six additional cities in Asia,
    the UK, France, the Czech Republic, Argentina, Egypt and New Zealand.

  Fiscal 2004 Milestones

  In April, management announced goals for the fiscal year ending March 31,
  2004. They are:

  - Continue to manage our transition from a development company to a
    financially strong, growing, and profitable business

  - Diversify our markets and technologies through expanded geographic
    coverage, new customer segments, new strategic partners, and the launch
    of both new and improved products

  - Strengthen Westport's technological leadership in the area of clean
    gaseous-fueled engines

  - Grow total consolidated revenues by at least 20% over fiscal 2003 (to
    $30 million)

  - Reduce cash invested in operations and capital by at least 30% (to $25
    million)

  - Maintain the introduction schedules of new CWI engine products,
    including the B Propane Plus, the 400 horsepower and the 450 horsepower
    versions of the ISX G, and the L Gas Plus.

  - Expand international business opportunities in the Americas, Europe,
    and Asia. Further develop local manufacturing relationships to enable
    enhanced future penetration of the Indian and China engine markets

"Westport and Cummins Westport are well positioned to make the commercial progress represented by these milestones during 2004," said Dr. Michael Gallagher, Westport's Chief Operating Officer. "We are, and will remain, focused on the right things to make the business a commercial success in a prudent, financially responsible way."

Westport Innovations Inc. is the leading developer of gaseous fuel engine technologies. It develops, manufacturers and sells a wide range of engines for commercial transportation applications such as trucks and buses through its joint venture with Cummins, Inc. Technology development alliances are in place with a number of other leading engine manufacturers, including MAN, Isuzu, and BMW.
