Argo Graphene Solutions Corp. Announces 
Closing of Previously Announced Upsized Private Placement

Vancouver, British Columbia – (Newsfile Corp. – June 4, 2026) – Argo Graphene Solutions Corp. (CSE: ARGO | OTCQB: ARLSF | Frankfurt: 94Y) (“Argo” or the “Company”), a leader in innovative graphene-based technologies, is pleased to announce that the Company has closed its previously announced upsized non-brokered private placement offering, issuing 1,154,220 units (the “Units”) at a price of CDN$0.55 cents per Unit for aggregate gross proceeds of CDN$634,821 (the “Offering”).

Each Unit is comprised of one common share in the capital of the Company and one transferable share purchase warrant. Each warrant entitles the holder to purchase one additional common share in the capital of the Company at a price of $0.70 per share until June 4, 2028.

In connection with the Offering, the Company paid aggregate finder’s fees of $23,815 and issued an aggregate of 43,300 finder’s warrants to eligible finders. Each finder’s warrant entitles the holder to purchase one common share in the capital of the Company at a price of $0.70 per share until June 4, 2028.

The Company plans to use the proceeds of the Offering for general working capital purposes and to continue its research and development of its graphene products.

All securities issued under the Offering are subject to a four-month hold period expiring October 5, 2026, in accordance with applicable Canadian securities laws.

A director of the Company participated in the Offering through a company for aggregate proceeds of $4,400, and such participation is considered to be a “related party transaction” for purposes of Multilateral Instrument 61-101 (“MI 61-101”). The Company is relying on the exemptions from the formal valuation requirements contained in section 5.5(a) of MI 61-101 and the minority shareholder approval requirements contained in section 5.7(1)(a) of MI 61-101 as the fair market value of the related party’s participation is not more than 25% of the Company’s market capitalization. The Company did not file a material change report in respect of the related party transaction at least 21 days before the closing of the Offering, which the Company deems reasonable in the circumstances in order to close the Offering in an expeditious manner.
