"received conditional approval to list its common shares on the Toronto Stock Exchange"
The Toronto Stock Exchange is Canada’s largest organized marketplace where shares of publicly traded companies are bought and sold, similar to a large, regulated marketplace for company ownership. It matters to investors because it provides transparent prices, rules that help protect buyers and sellers, and access to many Canadian and international businesses, so movements there can signal economic trends and affect portfolio values.
nasdaq regulatory
"into a Nasdaq-listed chemical technology developer with a strengthened balance sheet"
The Nasdaq is a stock exchange where many companies' shares are bought and sold, functioning much like a marketplace for investments. It matters to investors because it provides a platform to buy and sell ownership stakes in companies, helping them track the value of those companies and make informed decisions. As one of the largest and most technology-focused markets, it also reflects trends and developments in the business world.
canadian securities exchange regulatory
"expects to delist its common shares from the Canadian Securities Exchange"
A Canadian securities exchange is a regulated marketplace in Canada where companies’ stocks, bonds and other investment products are listed, bought, and sold. It matters to investors because it sets the rules, provides a visible price for securities and a place to trade — like a public marketplace that helps buyers and sellers meet, judge value, and convert holdings to cash under oversight intended to protect investors.
cse25 index financial
"Aduro is currently included in the CSE25 Index, which represents the 25 largest companies"
A CSE25 index is a stock-market benchmark that tracks the performance of twenty-five large, frequently traded companies listed on a particular exchange. Think of it as a basket of the exchange’s biggest, most active stocks that gives a quick snapshot of how the market’s leading firms are doing; investors use it to gauge overall market health, compare fund performance, or build products that mimic broad market moves.
cusip financial
"there will be no change in the trading symbol or CUSIP for the common shares"
A CUSIP is a nine-character alphanumeric code that uniquely identifies a U.S. or Canadian financial security—such as a stock, bond, or fund share—like a Social Security number for an investment. It matters to investors because brokers, exchanges and record-keepers use the CUSIP to match trades, track ownership, settle transactions and pull accurate records, reducing errors and ensuring money and securities go to the right place.
hydrochemolytic technical
"The Company’s Hydrochemolytic™ Technology relies on water as a critical agent"
Hydrochemolytic describes a chemical process where water and chemical agents are used together to break down materials or compounds, similar to using soap and warm water to dissolve grease but at industrial or laboratory scale. Investors care because this method can affect how cheaply and sustainably a product is made, influence regulatory or environmental risks, and alter supply chain costs or scalability for companies that rely on such processing.

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 21st 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.
