FORM 51-102F3

MATERIAL CHANGE REPORT

PowerBank Corporation (the “Company” or “PowerBank”)

505 Consumers Road, Suite 803

Toronto, Ontario M2J 4Z2

April 10, 2026

A news release announcing the material change was disseminated on April 13, 2026 via Cision.

The Company announced the termination of the sale of its Gainesville and Highway 28 projects.

PowerBank previously announced the sale of its Gainesville, Highway 28, Hardie and Rice Road solar power projects (the “Projects”) to a third party (the “Owner”) which included PowerBank’s continued engagement to construct the Projects through to commercial operation under EPC agreements.

The development and construction of the Projects was subject to the receipt of required permits. As the Gainesville and Highway 28 projects have not at this time received the required permits, the Owner has provided noticed to PowerBank to resell the Gainesville and Highway 28 projects back to PowerBank (the “Sell-Back Notice”). As a result of the Sell-Back Notice, the transactions for those two projects has been terminated and any funds advanced to PowerBank will be returned to the Owner. These funds total approximately US$2.35 million.

PowerBank remains confident in the underlying value of both assets. PowerBank will evaluate its strategic options for the Gainesville and Highway 28 projects, which may include developing them as owned independent power producer (IPP) assets or pursuing a sale to another third-party buyer. The Hardie and Rice Road projects are already under construction and are not affected by the Sell-Back Notice — with racking installation complete at Rice Road — and both are on track for module delivery in the second half of 2026 and commercial operation in Q1, 2027 following spring remobilization. As of the original transaction date, the Hardie project and Rice Rd project had a combined total project value of US$22.88 million to PowerBank.
