Auditor Opinion [Text Block] We have audited the accompanying consolidated statements of financial position of PowerBank Corporation and subsidiaries (the “Company”) as at June 30, 2026 and 2025, the related consolidated statements of comprehensive income (loss), changes in shareholders’ equity, and cash flows, for each of the two years in the period ended June 30, 2026, and the related notes (collectively referred to as the “financial statements”). In our opinion, the financial statements present fairly, in all material respects, the financial position of the Company as at June 30, 2026 and 2025, and its financial performance and its cash flows for each of the two years in the period ended June 30, 2026, in accordance with IFRS Accounting Standards as issued by the International Accounting Standards Board (IASB). 

The financial statements of the Company for the year ended June 30, 2024, before the effects of the retrospective adjustments to the disclosures for a change in the composition of reportable segments in Note 27 to the financial statements, were audited by predecessor auditors whose report, dated September 30, 2024, expressed an unqualified opinion on those financial statements. We also have audited the adjustments to the 2024 financial statements to retrospectively adjust the disclosures for a change in the composition of reportable segments in 2025, in Note 27 to the financial statements. Our procedures included (1) comparing the adjustment amounts of segment revenues, cost of goods sold, operating expenses, and total assets, liabilities and property plant, and equipment to the Company’s underlying analysis and (2) testing the mathematical accuracy of the reconciliation of segment amounts to the financial statements. In our opinion, such retrospective adjustments are appropriate and have been properly applied. However, we were not engaged to audit, review, or apply any procedures to the 2024 consolidated financial statements of the Company other than with respect to the retrospective adjustments, and accordingly, we do not express an opinion or any other form of assurance on the 2024 financial statements taken as a whole.
