LONDON, Ontario, June 24, 2026 (GLOBE NEWSWIRE) -- Aduro Clean Technologies Inc. ("Aduro" or the "Company") (Nasdaq: ADUR) (TSX: ACT) (FSE: 9D5), a clean technology company using the power of chemistry to transform lower value feedstocks, like waste plastics, heavy bitumen, and renewable oils, into resources for the 21^st century, today announced that, further to its previous news releases dated June 10, 2026 and June 15, 2026, it has completed a non-brokered private placement for gross proceeds of C$9,155,940.80 (US$6,564,810.21) from the sale of 431,884 common shares (the "LIFE Shares") at a price of C$21.20 (US$15.20) per LIFE Share (the "LIFE Offering") under the LIFE Exemption (as defined herein).

Subject to compliance with applicable regulatory requirements and in accordance with National Instrument 45-106 – Prospectus Exemptions ("NI 45-106"), the LIFE Offering was made to purchasers resident in all provinces of Canada, except Quebec, pursuant to the listed issuer financing exemption under Part 5A of NI 45-106 and Coordinated Blanket Order 45-935 – Exemptions from Certain Conditions of the Listed Issuer Financing Exemption of the Canadian Securities Administrators (the "LIFE Exemption"). The securities offered under the LIFE Offering pursuant to the LIFE Exemption are not subject to resale restrictions in accordance with applicable Canadian securities laws.

The Company intends to use the net proceeds of the LIFE Offering in the manner described in the Offering Document, including for technology development, commercialization activities, working capital and general corporate purposes.

In connection with the LIFE Offering, the Company paid aggregate cash finder's fees of C$539,994.53 to eligible finders in accordance with applicable securities laws and Toronto Stock Exchange requirements. Certain insiders of the Company participated in the LIFE Offering. The participation by insiders constitutes a "related party transaction" within the meaning of Multilateral Instrument 61-101 - Protection of Minority Shareholders in Special Transactions ("MI 61-101").

The Company did not file a material change report with respect to the insider participation more than 21 days before the expected closing of the LIFE Offering, as the details and amounts of the insider participation were not finalized until shortly prior to closing and the Company wished to close the transaction as soon as practicable for sound business reasons.

The Toronto Stock Exchange has conditionally approved the LIFE Offering. Final approval remains subject to customary post-closing requirements. The Company has relied on the exemption set forth in Section 602.1 of the TSX Company Manual in connection with the LIFE Offering.
