LONDON, Ontario, May 19, 2026 (GLOBE NEWSWIRE) -- Aduro Clean Technologies Inc. ("Aduro" or the "Company") (Nasdaq: ADUR) (CSE: 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, announces that it has received conditional approval to list its common shares on the Toronto Stock Exchange ("TSX") under the symbol "ACT". Final approval of the listing remains subject to the Company fulfilling all the requirements of the TSX, including receipt of all required documentation.

The Company will issue a news release once the TSX confirms the expected trading date. In connection with the TSX listing, the Company expects to delist its common shares from the Canadian Securities Exchange ("CSE"). Shareholders are not required to exchange their share certificates or take any other action in connection with the listing, as there will be no change in the trading symbol or CUSIP for the common shares.

"Since going public on the CSE in 2021, Aduro has advanced from an early-stage public technology company into a Nasdaq-listed chemical technology developer with a strengthened balance sheet and expanding industrial commercialization programs," said Ofer Vicus, Chief Executive Officer of Aduro. "The Company has progressed its Hydrochemolytic™ Technology ("HCT") through Next Generation Process ("NGP") Pilot Plant operating campaigns, First-of-a-Kind ("FOAK") industrial project development, commercial offtake engagement, license package development, and expanded petroleum applications. We sincerely thank the CSE for providing a platform for our early public-market growth and investor access and look forward to taking this next step with the Toronto Stock Exchange as we continue advancing HCT across waste plastics, heavy hydrocarbons, and renewable oils."

Aduro is currently included in the CSE25 Index, which represents the 25 largest companies on the Canadian Securities Exchange by market capitalization. This is a testament to Aduro's growing capital markets profile and shareholder recognition for the continued progress achieved since Aduro's public listing on the CSE. The proposed TSX listing represents the next stage in Aduro's capital markets evolution, supporting broader market visibility, increased access to institutional investors, and the continued development of the Company's Canadian public-market profile.
