Westport’s management and reflect Westport’s current expectations. Investors are cautioned
that all forward-looking statements involve risks and uncertainties that could cause actual
results to differ materially from those expressed in these forward-looking statements,
including, without limitation, Westport’s ability to develop viable fuel systems; Westport’s
ability to provide the capital required for research, product development, operations, and
marketing; product development, production and commercial launch delays; changing
environmental regulations; Westport’s ability to attract and retain key personal and business
partners; competition from conventional diesel fuelled engines; and Westport’s ability to
protect its intellectual property. These factors should be considered carefully and investors
should not rely on any forward-looking statements. Investors are encouraged to review
Management’s Discussion and Analysis and the Risk Factors section in Westport’s most
recently filed Annual Information Form and filings with securities regulators for a more
complete discussion of factors that could affect Westport’s future performance. We undertake
no obligation to update or revise any forward-looking statements, whether as a result of new
