Vancouver, British Columbia--(Newsfile Corp. - December 1, 2025) - Burcon NutraScience Corporation (TSX: BU) (OTCQB: BRCNF) ("Burcon" or the "Company"), a global technology leader in plant-based protein innovation, is pleased to announce that the Company insiders ("Insiders") have increased their commitment to participating in the previously announced non-brokered private placement (the "Offering") (see news release of the Company dated November 12, 2025) of convertible debentures (the "Convertible Debentures").

"Burcon insiders and its largest shareholders have once again shown confidence in our business plan and sales trajectory by expanding their investment," said Kip Underwood, Burcon's chief executive officer. "Their continued support underscores the commercial momentum we carry into 2026 and reinforces our ability to execute and deliver value for shareholders."

Burcon previously announced insider participation at a minimum of $2.0 million in principal amount. Since November 12, 2025, Burcon has received strong interest from potential investors in the Offering including increased interest from Insiders. Burcon anticipates the increased insider participation in the Offering could necessitate disinterested shareholder approval.

The Offering was expected to close on or about November 28, 2025. Given the increased interest in the Offering and the timing required to obtain shareholder approval, the timeline for closing the Offering will be extended. The Company is working with its key investors to finalize the terms and conditions of the Offering, which may change from what was previously announced. The Offering is subject to execution of subscription agreements by the placees and to certain conditions including, but not limited to, the receipt of all necessary regulatory approvals, including the approval of the TSX and disinterested shareholders.
