Aduro Clean Technologies Announces Closing of Underwriter's Over-Allotment Option in Public Offering

LONDON, Ontario, January 30, 2026 – Aduro Clean Technologies Inc., a pioneering clean technology company that leverages advanced chemistry to transform lower-value feedstocks such as waste plastics, heavy bitumen, and renewable oils into valuable 21st-century resources, has announced the successful closing of its underwriter's over-allotment option. This development follows the company's previously announced underwritten public offering in the United States.

Details of the Over-Allotment Exercise

Pursuant to the full exercise of the over-allotment option by D. Boral Capital LLC, Aduro issued an additional 260,869 common shares along with warrants to purchase an additional 130,434 common shares. This transaction generated total gross proceeds of approximately US$3 million. The common shares were sold in combination with accompanying half warrants, with each whole warrant exercisable into one common share of the company.

The warrants carry an exercise price of US$16.00 per share and are immediately exercisable. They will expire three years from the date of issuance, providing investors with a flexible option to acquire additional equity in the company.

Financial Advisors and Underwriters

D. Boral Capital LLC served as the lead underwriter for the offering, overseeing the execution of the over-allotment option. Roth Capital Partners acted as the financial advisor, providing strategic guidance throughout the process. Their involvement underscores the significance of this financing round for Aduro's growth trajectory.

Use of Proceeds

Aduro plans to allocate the net proceeds from the offering toward several key initiatives. The primary focus will be on expenditures related to the construction of its Demonstration-Scale Plant, a critical step in scaling up its innovative technologies. Any remaining funds will be directed toward ongoing research and development efforts, general corporate purposes, and working capital requirements. This strategic allocation aims to accelerate the company's mission of advancing sustainable resource transformation.

Regulatory Framework

The offering was conducted under an effective shelf registration statement on Form F-10, which was filed with the U.S. Securities and Exchange Commission on December 15, 2025, and became effective immediately. Additionally, the company's Canadian short form base shelf prospectus, dated December 15, 2025, provided the foundation for this transaction. It is important to note that the securities were offered and sold exclusively in the United States, with no offerings made to Canadian purchasers.

Prospective investors are encouraged to review the prospectus and related documents filed with regulatory authorities for comprehensive information about the company and the offering. This press release does not constitute an offer to sell or a solicitation to buy any securities, and such transactions are subject to applicable securities laws and exemptions.
