BALLARD POWER SYSTEMS INC. Notes to Condensed Consolidated Interim Financial Statements Three months ended March 31, 2024 and 2023 Unaudited (Tabular amounts expressed in thousands of U.S. dollars, except number of shares)

1. Reporting entity:

The principal business of Ballard Power Systems Inc. (the "Corporation") is the design, development, manufacture, sale and service of proton exchange membrane ("PEM") fuel cell products for a variety of applications, focusing on power products for bus, truck, rail, marine, stationary and emerging market (material handling, off-road and other) applications, as well as the delivery of services, including technology solutions, after sales services and training.A fuel cell is an environmentally clean electrochemical device that combines hydrogen fuel with oxygen (from the air) to produce electricity.

The Corporation is a company domiciled in Canada and its registered office is located at 9000 Glenlyon Parkway, Burnaby, British Columbia, Canada, V5J 5J8. The condensed consolidated interim financial statements of the Corporation as at and for the three months ended March 31, 2024 and 2023 comprise the Corporation and its subsidiaries.

2. Basis of preparation:

(a) Statement of compliance:

These condensed consolidated interim financial statements of the Corporation have been prepared in accordance with International Accounting Standard ("IAS") 34 Interim Financial Reporting as issued by the International Accounting Standards Board ("IASB"), on a basis consistent with those material accounting policies followed in the most recent annual consolidated financial statements except as noted below, and therefore should be read in conjunction with the December 31, 2023 audited consolidated financial statements and the notes thereto.

The condensed consolidated interim financial statements were authorized for issue by the Audit Committee of the Board of Directors on May 6, 2024.

(b) Basis of measurement:

The condensed consolidated interim financial statements have been prepared on the historical cost basis except for the following material items in the statement of financial position:

•Financial assets classified as measured at fair value through profit or loss (FVTPL); and

•Employee future benefits liability is recognized as the net of the present value of the defined benefit obligation, less the fair value of plan assets.

(c) Functional and presentation currency:

These condensed consolidated interim financial statements are presented in U.S. dollars, which is the Corporation's functional currency.

(d) Use of estimates:

The preparation of the condensed consolidated interim financial statements in conformity with IFRS accounting standards requires the Corporation's management to make estimates and assumptions that affect the application of accounting policies and the reported amounts of assets, liabilities, income and expenses. Actual results may differ from these estimates.

2. Basis of preparation (cont'd):

(d) Use of estimates (cont'd):

Estimates and underlying assumptions are reviewed on an ongoing basis. Revisions to accounting estimates are recognized in the period in which the estimates are revised and in any future periods affected.

Significant areas having estimation uncertainty include revenue recognition, asset impairment, warranty provision, inventory and onerous contract provision, and fair value measurement (including investments). These assumptions are unchanged in these condensed consolidated interim financial statements and are the same as those applied in the Corporation's consolidated financial statements as at and for the year ended December 31, 2023.

(e) Future operations:

The Corporation is required to assess its ability to continue as a going concern or whether substantial doubt exists as to the Corporation's ability to continue as a going concern into the foreseeable future. The Corporation has forecast its cash flows for the foreseeable future and despite the ongoing volatility and uncertainties inherent in the business, the Corporation believes it has adequate liquidity in cash and working capital to achieve its liquidity objective. The Corporation's ability to continue as a going concern and realize its assets and discharge its liabilities and commitments in the normal course of business is dependent upon the Corporation having adequate liquidity and achieving profitable operations that are sustainable.

The Corporation's strategy to mitigate this uncertainty is to continue its drive to attain profitable operations that are sustainable by executing a business plan that continues to focus on revenue growth, improving overall gross margins, maintaining discipline over cash operating expenses, managing working capital and capital expenditure requirements, and securing additional financing to fund operations as needed until the Corporation does achieve profitable operations that are sustainable. Failure to implement this plan could have a material adverse effect on the Corporation's financial condition and or results of operations.

3. Material accounting policies:

Effective January 1, 2024, the Corporation adopted a number of new standards and interpretation, but they did not have a material impact on the Corporation's condensed consolidated interim financial statements.

The accounting policies in these condensed consolidated interim financial statements are the same as those applied in the Corporation's consolidated financial statements as at and for the year ended December 31, 2023.

4. Critical judgments in applying accounting policies and key sources of estimation uncertainty:

Critical judgments in applying accounting policies:

Critical judgments that management has made in the process of applying the Corporation's accounting policies and that have the most significant effect on the amounts recognized in the condensed consolidated financial statements are limited to management's assessment of the Corporation's ability to continue as a going concern (note 2(e)).

4. Critical judgments in applying accounting policies and key sources of estimation uncertainty (cont'd):

Key sources of estimation uncertainty:

Key assumptions concerning the future and other key sources of estimation uncertainty that have significant risk of resulting in a material adjustment to the reported amount of assets, liabilities, income and expenses within the next fiscal year include the following: revenue recognition, asset impairment, warranty provision, inventory and onerous contracts provision, and fair value measurement (including investments). These assumptions are unchanged in these condensed consolidated interim financial statements and are the same as those applied in the Corporation's consolidated financial statements as at and for the year ended December 31, 2023.

(b) Credit risk:

IFRS 9 Financial Instruments requires impairment losses to be recognized based on "expected losses" that will occur in the future, incorporating forward looking information relating to defaults and applies a single ECL impairment model that applies to all financial assets within scope. ECLs are a probability-weighted estimate of credit losses. Credit losses are measured as the present value of all cash shortfalls (i.e. the difference between the cash flows due to the Corporation in accordance with the contract and the cash flows that the Corporation expects to receive). Under IFRS 9, at each reporting date the Corporation is required to assess whether financial assets carried at amortized cost are credit-impaired.

As a result of this review for the three months ended March 31, 2024, the Corporation did not recognize any additional estimated ECL impairment losses. At March 31, 2024, the total amount accrued was $500,000.
