Vancouver, British Columbia--(Newsfile Corp. - June 25, 2026) - Argo Graphene Solutions Corp. (CSE: ARGO) (OTCQB: ARLSF) (FSE: 94Y) (" Argo " or the " Company ") is pleased to announce that, further to its news release dated May 26, 2026, the Company has closed its previously announced license agreement (the " Agreement ") with Grapherry, Inc. (" Grapherry ") in respect of Grapherry's proprietary STREAM graphene production platform and all related intellectual property (the " Technology "). Pursuant to the Agreement, Grapherry has granted Argo an exclusive worldwide license to use, develop, manufacture, and commercialize the Technology for an initial term of 10 years (the " License "). Upon the issuance of all consideration shares and warrants described below, full ownership of the Technology will automatically transfer outright to Argo.

As consideration for the License, Argo agreed to issue to Grapherry up to 11,000,000 common shares and 5,500,000 share purchase warrants. On closing, Argo issued to Grapherry 2,500,000 common shares and all 5,500,000 warrants upfront, subject to vesting in accordance with the performance-based milestones set out below. The balance of 8,500,000 common shares will be issued in stages upon the satisfaction of the following milestones: 2,500,000 common shares upon completion of a CAD $1,000,000 equity financing by Argo; 3,000,000 common shares upon the commissioning of a graphene production facility meeting minimum production capacity specifications, as confirmed by an independent third party testing and verification body; and 3,000,000 common shares upon Argo achieving CAD $1,000,000 in gross revenue from the commercialization of the Technology.

Each warrant is exercisable to acquire one common share of the Company at a price of CAD $0.75 per share for a period of five years from the date of issuance. All 5,500,000 warrants were issued on closing and will vest and become exercisable in tranches upon the satisfaction of the corresponding milestones, being 2,500,000 warrants on closing, 1,500,000 warrants upon completion of the equity financing milestone, and 1,500,000 warrants upon commissioning of the production facility milestone. To the extent that the issuance of common shares to Grapherry under the Agreement would result in the creation of a control person, Argo will seek shareholder approval prior to any such issuance as required by the policies of the Canadian Securities Exchange.

In addition, Grapherry may not exercise any warrants where the issuance of common shares upon such exercise would result in Grapherry holding more than 19.99% of the issued and outstanding common shares of the Company on an undiluted basis, unless prior shareholder approval has been obtained. As previously disclosed, in connection with the Agreement, Argo agreed to issue 400,000 common shares to a third-party consultant. The shares have been issued as share-based compensation for consulting and advisory services provided to the Company in connection with the Agreement.

The compensation was not calculated by reference to, and is not payable as a percentage of, the consideration payable to Grapherry under the Agreement. All shares and warrants issued under the Agreement, including the shares issued to the consultant, are subject to a statutory four-month hold period expiring on October 25, 2026.
