LONDON, Ontario, May 26, 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, is pleased to announce that it received final approval to list its common shares on the Toronto Stock Exchange (“TSX”) under the symbol “ACT”. Trading on the TSX will commence at market open on May 27, 2026.

In connection with the TSX listing, the Company will concurrently 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. Aduro common shares will continue to trade on the Nasdaq Capital Market under the symbol “ADUR” and Frankfurt Stock Exchange under the symbol “9D5”.

The TSX is the senior equities marketplace in Canada and one of the world’s leading public equities markets. According to TMX Group, as of April 2026, the TSX had 2,176 listed issuers and approximately C$6.8 trillion in market capitalization of listed issues across a broad range of sectors, including resources, financials, industrials, technology, and clean technology. The listing represents the next step in the Canadian capital markets development of Aduro and aligns the Canadian listing profile of the Company with its broader public-market presence in the United States and Europe.

Aduro previously traded on the CSE and was included in the CSE25 Index, a benchmark of the 25 largest companies on the exchange by market capitalization. The Company appreciates the role the CSE has played in supporting its early public-market growth and development.

The TSX listing is expected to support the next stage of the Company’s capital markets development by providing:

Senior Exchange Recognition: Listing on the TSX places Aduro on the senior equities marketplace in Canada and reflects the progression of the Company through the applicable listing review process.
Broader Institutional Access: The TSX is widely recognized by Canadian and international institutional investors, and the listing is expected to improve accessibility for Aduro within institutional investment mandates, research platforms, and capital markets workflows, including mandates that give preference to senior-exchange issuers.
Enhanced Trading Infrastructure: TSX-listed securities benefit from Canada’s senior equity market infrastructure, including efficient access to liquidity, quality execution, broader broker-dealer participation, market-making support, and visibility across institutional trading systems.
Index Eligibility Pathway: Listing on the TSX positions Aduro to be evaluated against applicable Canadian index eligibility criteria, including criteria related to market capitalization, trading liquidity, public float, and other issuer-level requirements. Inclusion in any index is not automatic and remains subject to the applicable index methodology and future Company performance.
Market Visibility and Research Discoverability: The TSX listing is expected to increase Aduro’s visibility within Canadian capital markets and improve discoverability among institutional investors, analysts, investment dealers, and financial media.
Multi-Market Investor Reach: With listings on the Toronto Stock Exchange, the Nasdaq Capital Market, and the Frankfurt Stock Exchange, Aduro maintains access to investor communities in Canada, the United States, and Europe as it advances its commercialization pathway.

“The commencement of trading on the Toronto Stock Exchange marks an important step in the capital markets development of Aduro and reflects the progress the Company has made since first entering the public markets in Canada,” said Ofer Vicus, Chief Executive Officer of Aduro. “As we advance NGP Pilot Plant operating campaigns, FOAK industrial planning, and commercial engagement across our Hydrochemolytic™ Technology applications, the TSX listing provides a senior Canadian market platform that better aligns with Aduro’s current stage of development and international investor profile. We are grateful to the Canadian Securities Exchange for supporting the early public-market growth of Aduro, and we thank our shareholders, partners, and the Aduro team for helping us reach this next milestone.”
