• Shareholders face a clear choice: a Board executing a disciplined plan for growth already in motion, or a return to the instability and value destruction of the past
• Actions of former Chief Executive Officer create an irreconcilable conflict of interest and threaten further value destruction

• Letter to shareholders and information circular available on questortech.com/vote and www.sedarplus.ca

CALGARY, Alberta, Aug. 11, 2026 (GLOBE NEWSWIRE) -- Questor Technology Inc. (“Questor” or the “Company”) (TSX-V: QST) today advised shareholders that it has issued a letter to shareholders and filed a Management Information Circular (the “Circular”) in connection with the upcoming Annual General Meeting of Shareholders (the “Meeting”) scheduled for September 9, 2026 at 1:00 p.m. MDT.

The Circular and accompanying materials are available on Questor’s website at questortech.com/vote and SEDAR+ at sedarplus.ca.

A Critical Turning Point for Shareholders: Continue to Move Forward or Risk a Return to Instability

Questor is at a significant inflection point, having undergone a leadership transition and embarking on a focused strategy. Since the termination of former Chief Executive Officer, Audrey Mascarenhas, in April 2026, the independent directors of your Board have taken decisive action to reposition the Company, including appointing new leadership, reactivating core markets, and establishing a special committee of independent directors responsible for restoring stability and driving a refresh of the Company’s strategic direction.

“The independent directors of your Board and refreshed leadership team have a plan in motion, and we have the right team in place to execute it,” said Paul Huizinga, Chair of the Board. “We have set a clear course for growth: Questor's certified technology addresses a clear and growing market need, and we are focused entirely on delivering results for shareholders.”

The Company has received advance notice from Ms. Mascarenhas in accordance with the Company's advance notice by-law that she intends to nominate an alternate slate of directors at the Meeting, including herself. The notice has been reviewed for compliance with the Company's by-law requirements.

Shareholders now face a defining choice between a focused and disciplined Board with a clear plan for growth already in motion, or risk handing control back to the former Chief Executive Officer, whose tenures were marked by failed leadership, governance concerns and ongoing litigation against the Company.

Audrey Mascarenhas’ Track Record of Value Destruction and Failed Leadership

During Ms. Mascarenhas’ tenures as Chief Executive Officer, the Company experienced shifting strategies and high turnover, including the resignation of six independent directors, key personnel, and the Company’s independent external auditors. The result was an approximately $139 million collapse in market capitalization as the share price fell 95% from its February 2020 high until the day of her second termination in April 2026. While shareholder value eroded, Ms. Mascarenhas extracted over $7 million in compensation since her initial appointment as Chief Executive Officer, which is over 5 times the current market value of her entire ownership stake.

Her ongoing litigation against Questor and its independent directors, seeking more than $26 million in damages, creates an irreconcilable conflict of interest. If successful in reinstating herself as Chief Executive Officer for a third time, shareholders should expect Ms. Mascarenhas to seek reimbursement of her fees associated with her campaign. If Ms. Mascarenhas wins, shareholders will lose.

Over the past three years, the independent directors of two separate boards have concluded that Ms. Mascarenhas’ termination was necessary, following serious governance failures. The Company is now moving forward with the strategic focus required to deliver results.

Restoring Operational Discipline and Growth

The independent directors of the Board and refreshed leadership team have taken significant steps to stabilize the business and position Questor for near-term growth. This includes appointing Mike Lindsay as interim President and Chief Executive Officer, while initiating a comprehensive search for a permanent leader. To drive near-term results, the Company has also hired Craig Joyce as Senior Director of Sales to reactivate core North American revenue streams and has engaged an independent consultant to provide a "cold eyes" technical review of Questor’s integrated Organic Rankine Cycle Power Generation Solution and assess market opportunities.

The independent directors are committed to restoring what made Questor a profitable and market-leading company capable of generating significant free cash flow. With 99.99% combustion efficiency and ISO 14034 verified technology, Questor is uniquely positioned to meet audit-grade measurement required in a tightening regulatory environment – converting the Company's technical promise into consistent results for all shareholders.

A Specialized Board Built for Questor’s Next Phase

Questor’s independent director nominees bring the deep expertise in energy operations, technology and capital markets required for Questor’s next phase:

• Paul Huizinga: A Partner with Senex Advisory and a proven business leader in driving innovation and growth. He previously served as Regional Managing Director for Accenture, Chief Executive Officer of FT Services and Senior Vice President of Operations for Worley.
• Mike Krayacich: Co-founder and Chief Technology Officer of Portage Energy, leading technical strategy for sustainable aviation fuel creation. He previously spent 20 years at Suncor in senior leadership and executive roles including major project execution and leading large technical organizations.
• Jason Smith: An international oil and gas leader with extensive experience managing onshore and offshore businesses. He is currently a Principal at 26 North Ventures LLC and was previously the Chief Operating Officer of QuarterNorth Energy. He also serves on the Board of Directors of B-32 Exploration.
• Saj Shapiro: A seasoned executive with over 25 years of leadership experience in energy, engineering and international growth. He was previously Managing Director at BMO Capital Markets and Chief Executive Officer of BMO Radicle.
