ADURO CLEAN TECHNOLOGIES ANNOUNCES FILING OF AMENDED AND RESTATED LIFE OFFERING DOCUMENT FOLLOWING CLOSING OF PUBLIC OFFERING

Aduro Clean Technologies Inc., further to its previous announcement dated June 10, 2026, of a non-brokered private placement of up to 471,698 common shares at a price of $15.20 (U.S.) ($21.20 (Canadian)) per offered share for gross proceeds of up to $7,169,810 (U.S.) ($9,999,734 (Canadian)), has filed an amended and restated offering document following the completion of its underwritten public offering as announced on June 11, 2026, in accordance with applicable securities laws.

The LIFE (listed issuer financing exemption) offering is expected to close on or about June 19, 2026, or such other date as the company may determine, subject to applicable securities and the policies of the Toronto Stock Exchange. All other terms of the LIFE offering remain unchanged from those previously disclosed in the company's previous announcement dated June 10, 2026.

The amended and restated LIFE offering document is available under the company's profile on SEDAR+ and on the company's website. Prospective investors should read the amended and restated LIFE offering document before making an investment decision.

The company anticipates that directors and/or officers of the company may participate in the LIFE offering, however, there is no such commitment or agreement in place with any director or officer of the company at this time. Any participation in the LIFE offering by insiders constitutes a related party transaction as defined under Multilateral Instrument 61-101, Protection of Minority Security Holders in Special Transactions. However, the company expects to rely on exemptions from the formal valuation and minority shareholder approval requirements of MI 61-101 based on the fact neither the fair market value of the LIFE shares subscribed for by the insiders (if any), nor the consideration for the LIFE shares paid by such insiders, would exceed 25 per cent of the company's market capitalization as at the date of this news release.

The company is relying on the exemption set forth in Section 602.1 of the TSX company manual in connection with the LIFE offering, which provides that the TSX will not apply certain standards to certain transactions involving eligible interlisted issuers on a recognized exchange. The TSX has conditionally approved the LIFE offering. Final approval of the LIFE offering by the TSX remains subject to the completion of customary conditions by the company.

All amounts in this news release are in United States dollars unless otherwise indicated. All foreign exchange calculations set forth in this news release is based on the exchange rate posted by the Bank of Canada on June 9, 2026, of $1 (U.S.) to $1.3947 (Canadian).
