CALGARY, Alberta, Oct. 27, 2026 (GLOBE NEWSWIRE) -- Questor Technology Inc. (“Questor” or the “Company”) (TSX-V: QST) announces the appointment of Audrey Mascarenhas, F.C.A.E., P.Eng., as President and Chief Executive Officer, effective immediately. Ms. Mascarenhas succeeds Mike Lindsay, who served as Interim President and Chief Executive Officer since April 2026.

Ms. Mascarenhas has been with Questor since 1999 and has spent more than 25 years developing and commercializing its clean combustion technology and continues to grow its role in effective emissions reduction for the oil and gas, energy, industrial, and municipal sectors. She served as President and Chief Executive Officer from 2005 to April 2026. Before Questor, she spent 17 years at Gulf Canada Resources (1982–1999) in upstream exploration and corporate transactions, giving her more than four decades of experience in the energy industry. She is a professional engineer with deep experience in commercializing clean technology, serving international energy markets, and TSXV governance and disclosure, including her board experience at TMX Group Limited.

“Questor’s technology has a strong track record in achieving unprecedented performance, and interest from our global and local clients remains high. My priority is to bring value-add solutions to our clients, with disciplined execution and a clear focus on clients who value what we do. I am grateful to the shareholders and employees who continue to support the Company, and I look forward to getting back to work,” said Ms. Mascarenhas.

The Company’s annual general meeting, originally scheduled for June 24, 2026, was rescheduled to June 15, 2026, and subsequently postponed despite indications from the proxy tally that shareholders wanted a change. The meeting was finally held on September 9, 2026, and shareholders again voted for a change in Board composition. The Company incurred significant costs associated with the proxy contest and related proceedings. The Company’s new Board is aligned with and invested in Questor’s success and, with the leadership transition complete, is focused on disciplined execution, commercial growth and long-term value for shareholders.

Questor now moves forward with renewed focus on its global and local opportunities. Discussions with Tier 1 clients have resumed following Ms. Mascarenhas’ return, and the Board and management believe the Company is well positioned to convert this renewed engagement into long-term growth for shareholders.
