Endnotes:
¹ EBITDA and Adjusted EBITDA are non-GAAP measures used to assist in assessing Ballard’s financial performance and liquidity. Non-GAAP measures do not have any standardized meaning prescribed by GAAP and are therefore unlikely to be comparable to similar measures presented by other companies. EBITDA measures net loss attributable to Ballard Power Systems Inc. after excluding interest expense, income taxes expense, depreciation of property, plant and equipment, amortization of intangible assets and goodwill impairment charges. Adjusted EBITDA measures EBITDA adjusted for stock-based compensation, investment and other income, transactional gains and losses and acquisition costs. EBITDA and Adjusted EBITDA include the impact attributable to Ballard’s controlling interest in Dantherm Power. Ballard believes that EBITDA and Adjusted EBITDA assist investors in assessing actual and future performance.
