Ballard Reports First Quarter 2015 Results
Net Income of $7.0M on strength of deal with Volkswagen Group

VANCOUVER, CANADA – Ballard Power Systems (NASDAQ: BLDP; TSX: BLD) today announced its consolidated financial results for the first quarter ended March 31, 2015. All amounts are in U.S. dollars unless otherwise noted and have been prepared in accordance with International Financial Reporting Standards (IFRS).

“In the first quarter, we made progress building our foundation for long-term growth by achieving several key deliverables,” said Randy MacEwen, President and CEO. “Most notably, through our newly positioned Technology Solutions platform, we completed a landmark transaction with Volkswagen Group that surfaced value from our intellectual property portfolio by combining it with our intellectual capital-intensive engineering services. This transaction enabled us to report a $7.0 million profit in the first quarter and strongly positions us for long-term automotive fuel cell exposure.”

“We continue to expect 2015 revenue to be heavily weighted in the second half of the year. We are seeing significant progression of our sales pipeline based on repeat customer business and complemented by attractive new customers in both our Power Products and Technology Solutions platforms.”

Total revenue of $9.3 million, a decrease of 34% due to an expected decline in Technology Solutions.
Gross margin of 11%, a decrease due to the absence of high margin licensing revenue as well as higher unabsorbed overhead and related costs from significantly lower Telecom Backup Power shipments.
Cash operating costs2 of $7.9 million, an increase driven by higher net research and product development costs, which more than offset minor reductions in general and administrative costs and sales and marketing costs.
Adjusted EBITDA2 of ($5.1) million, a decline driven by lower gross margin resulting from an overall decrease in revenue, including the absence of high margin licensing revenue as a result of the termination of contracts with Azure in China in late-2014.
Net income of $7.0 million or $0.05 per share, improvements of 283% and 269% respectively, reflecting the $14.2 million gain on the sale of certain intellectual property assets to Volkswagen Group.
Cash used by operating activities of ($5.4) million, an improvement of 19%. This reflects cash operating loss of ($5.8) million, partially offset by an improvement in working capital of $0.4 million as a result of the timing of revenues and related customer collections.
Cash reserves of $47.6 million at March 31. Cash reserves were fortified in the quarter by approximately $29 million as a result of the transaction with Volkswagen Group.

Power Products:
The Power Products platform – consisting of fuel cell products for the Telecom Backup Power market, the Material Handling market and Development Stage Markets – generated revenue of $4.9 million in the quarter, approximately flat year-over-year but reflecting a shift in product mix as detailed below.

Telecom Backup Power
Revenue of $0.6 million, an expected decline resulting from fewer product shipments, largely the result of continued delays in the receipt of orders from several telecom service providers.
Successfully met stipulations specified by the New York City Fire Department for approval of ElectraGen™-ME methanol-fueled system for rooftop deployments.

Material Handling
Revenue of $2.6 million, representing growth of 29%, driven by an increase in fuel cell stack shipments.
Plug Power, Ballard’s premier customer in this market, has stated an expectation for 2015 shipment growth of its GenDriveTM systems.

Development Stage Markets
Revenue of $1.7 million, representing growth from $0.1 million in Q1 last year (adjusted for a reclassification of licensing revenue to Technology Solutions), as a result of increased power module shipments for use in buses.
Delivered 3 next-generation FCvelocityTM-HD7 power modules to a bus partner in China, as part of a purchase order for 8 power modules under a supply agreement signed earlier in the quarter, all of which are expected to be shipped this year.
Shipped 1 FCvelocity™-HD6 power module to BAE Systems for integration into a bus to be deployed in Ohio.

Technology Solutions:
The Technology Solutions platform – consisting of engineering services and intellectual property licensing – generated revenue of $4.4 million in the quarter, a year-over-year decline of 51%, since revenue in Q1 2014 had included licensing contracts in China that Ballard subsequently terminated and also reflected a cadence in engineering services contract work for Volkswagen AG that was weighted toward the early portion of last year.

In Q1 2015 Ballard announced a landmark transaction with Volkswagen Group:
Contract value of approximately $80 million for the transfer of certain automotive-related fuel cell intellectual property and a 2-year extension to the existing engineering services contract;
As a result of the transaction, the Company booked $14.2 million as a gain on the sale of intellectual property in Q1 2015.
Signed a contract with a global automotive OEM to advance the customer’s fuel cell program through development stages.
Signed a contract with Ardica Technologies for the next phase of work toward development of a wearable fuel cell power system for use by soldiers.

Endnotes:
1 We report our results in the single operating segment of Fuel Cell Products and Services. Our Fuel Cell Products and Services segment consists of the sale and service of fuel cell products for our “commercial stage” markets of Telecom Backup Power and Material Handling and for our “development stage” markets of Bus and Distributed Generation, as well as the delivery of Technology Solutions including engineering services and the license and sale of our extensive intellectual property portfolio and fundamental knowledge for a variety of fuel cell applications.

We made changes to the composition of revenues in our Fuel Cell Products and Services segment in the first quarter of 2015. As a result, licensing revenues of $1.6 million for the first quarter of 2014 previously recorded as “development stage” Bus revenues have been retroactively reclassified as Technology Solutions revenues.

2 Cash Operating Costs measures operating expenses excluding stock based compensation expense, depreciation and amortization, impairment losses or recoveries on trade receivables, 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 impairment losses or recoveries on trade receivables, 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.

3 Includes gain of $14.2 million on sale of intellectual property to Volkswagen Group.
