Exhibit EX-99.1

VANCOUVER, CANADA– Ballard Power Systems (NASDAQ: BLDP)(TSX: BLD) today announced its consolidated financial results for the first quarter ended March 31, 2013. All amounts are in U.S. dollars unless otherwise noted and have been prepared in accordance with International Financial Reporting Standards (IFRS).

John Sheridan, President and CEO said, “Q1 results reflect a positive start to the year for Ballard, with a markedly stronger balance sheet and improvements in all key financial performance metrics. With revenue growth of 22%, in tandem with a 3-point increase in gross margin and 10% reduction in cash operating costs, Adjusted EBITDA improved 27%. Further, these improving trends are expected to strengthen starting in Q2, with the beginning of the full ‘run rate’ impact of the multi-year VW engineering services contract. As such, Ballard has confirmed full year guidance for revenue growth in excess of 30% and improvement in Adjusted EBTIDA in excess of 50%.”

With the January 31, 2013 sale of the non-core Material Products division, comparisons made below to 2012 are on a continuing operations basis, excluding the Material Products division, consistent with IFRS accounting principles.

Endnote:
1 Cash Operating Costs measures operating expenses excluding stock based compensation expense, depreciation and amortization, restructuring charges, acquisition costs and financing charges. EBITDA measures net loss attributable to Ballard Power Systems Inc. excluding finance expense, income taxes, depreciation of property, plant and equipment, amortization of intangible assets, and goodwill impairment charges. Adjusted EBITDA adjusts EBITDA for stock based compensation expense, transactional gains and losses, asset impairment charges, finance and other income and acquisition costs. Normalized Net Loss measures net loss attributable to Ballard from continuing operations, excluding transactional gains and losses and asset impairment charges.

Note that Cash Operating Costs, EBITDA, Adjusted EBITDA and Normalized Net Loss, are non GAAP measures. Non GAAP measures do not have any standardized meaning prescribed by GAAP and therefore are unlikely to be comparable to similar measures presented by other companies. Ballard believes that Cash Operating Costs, EBITDA, Adjusted EBITDA and Normalized Net Loss assist investors in assessing Ballard’s operating performance and liquidity. These measures should be used in addition to, and not as a substitute for, net income, cash flows and other measures of financial performance and liquidity reported in accordance with GAAP. For a reconciliation of Cash Operating Costs, EBITDA, Adjusted EBITDA and Normalized Net Loss to the Consolidated Financial Statements, please refer to Ballard’s Management’s Discussion & Analysis.
