TORONTO, March 05, 2026 (GLOBE NEWSWIRE) -- HydroGraph Clean Power Inc. (CSE: HG) (OTCQB: HGRAF) (“HydroGraph” or the “Company”), a leading producer of ultra-pure graphene, is pleased to announce the closing of its previously disclosed best-efforts, fully marketed brokered private placement for aggregate gross proceeds of C$29,999,974.80. The offering consisted of 5,882,348 units of the Company (the “Units”) at a price of C$5.10 per Unit (the “Offering”), completed by way of a private placement under Part 5A of National Instrument 45-106 – Prospectus Exemptions, as amended by Coordinated Blanket Order 45-935 of the Canadian Securities Administrators (the “Listed Issuer Financing Exemption”) and other available prospectus exemptions.

Each Unit consisted of (i) one common share of the Company (each, a “Common Share”) and (ii) one-half (½) of one common share purchase warrant of the Company (each whole warrant, a “Warrant”). Each Warrant entitles the holder to purchase one Common Share at an exercise price of C$6.10 for a period of 36 months following the closing date of the Offering (the “Closing Date”), subject to the Company’s acceleration right described below.

Warrant Acceleration Provision

Following the Closing Date, if the daily volume-weighted average trading price of the Company’s common shares on the Canadian Securities Exchange (the “Exchange”) equals or exceeds C$12.20 for ten (10) consecutive trading days, the Company may, at its discretion, accelerate the expiry date of the Warrants by providing not less than thirty (30) days’ notice to Warrant holders via press release.

Use of Funds

The net proceeds from the Offering will be used for establishing and staffing the Company’s new Texas headquarters, advancing the development of its second graphene production facility in Texas, expanding marketing and sales initiatives, supporting ongoing research and development programs, strengthening the Company’s intellectual property portfolio and strategic partnerships, and funding general working capital needs.

“This financing represents an important milestone for HydroGraph as we continue to accelerate our growth strategy,” said Kjirstin Breure, CEO and President of HydroGraph. “The strong investor support reflects confidence in our technology and long-term vision. The proceeds will help us scale operations, advance our Texas expansion, and continue strengthening our leadership in ultra-pure graphene solutions.”

Lead Agent

The Offering was conducted on a best-efforts, fully marketed basis by Canaccord Genuity Corp., acting as agent and sole bookrunner (the “Agent”). The Company: (i) paid the Agent a cash commission equal to 6.0% of the gross proceeds of the Offering (reduced to 3.0% of the gross proceeds for Units sold to purchasers on the president’s list); and (ii) issued the Agent broker warrants in an amount equal to 6.0% of the number of Units sold (reduced to 3.0% for Units sold to purchasers on the president’s list), which broker warrants are each exercisable to acquire one Common Share at an exercise price of C$5.63 for a period of 36 months following the Closing Date.
