Insights

Litigation and risk analyst

Ontario court dismisses over $6M in claims, easing Zentek’s litigation overhang.

The Ontario Superior Court dismissed substantially all monetary claims brought by the former CEO and his consulting firm, including items that originally totaled more than $6 million. This removes a sizable potential liability that had been hanging over Zentek for years.

The Court rejected success fee, severance, unpaid wage, defamation, and indemnification claims, while also finding the founder shares at issue were properly issued and not subject to cancellation. Economically, the net result is strongly favorable for Zentek, as no damages were awarded against the company.

With this judgment, Zentek can redirect management attention and resources toward its core platforms—Albany Graphite, ZenGUARD™ and Triera. Future disclosures about commercialization progress on these technologies will shape how meaningful this legal clean‑up is for the company’s longer‑term value.

Zentek Ltd. Receives Favorable Judgment in Long-Standing Litigation

Ontario Superior Court Dismisses Claims Originally

Exceeding $6 Million Against Zentek

Guelph, Ontario, March 13, 2026 - Zentek Ltd. (TSX-V: ZEN) (NASDAQ: ZTEK) ("Zentek" or the "Company") announces that the Ontario Superior Court of Justice (Commercial List) has issued its Reasons for Judgment dated March 12, 2026, in the companion actions Eveleigh et al. v. Zenyatta; Zentek v. Eveleigh et al., 2026 ONSC 1510.

Background

The litigation arose following the removal of Aubrey Eveleigh, the Company's founder and former President and Chief Executive Officer, by shareholders at a special meeting held on May 11, 2018. The two companion actions were tried together before Justice Osborne of the Ontario Superior Court of Justice.

Outcome

The Court dismissed substantially all claims advanced by Mr. Eveleigh and his consulting firm, Eveleigh Geological Consulting Inc. Original claims, as filed, exceeded $6 million. At trial, the claims were refined and the Court denied all remaining monetary claims, specifically:

• A Success Fee claim of $282,500 - denied on the basis that the pre-feasibility study required to trigger the payment obligation was never commenced;

• Severance claims totaling $1,350,000 under the President's Agreement and related Memorandum of Agreement - found to be void and unenforceable as a result of breaches of fiduciary duty;

• Unpaid wages of $51,748.82 - denied;

• Defamation damages of $75,000 - denied, with the Court finding the relevant statements were factually accurate; and

• Indemnification claims of approximately $194,000 in costs and disbursements - denied.

With respect to Zentek's claim for cancellation of 4.5 million founder shares and disgorgement of profits, the Court found that the shares had been properly issued and that there was no basis to set aside the issuance.

CEO Comment

"This judgment closes a chapter that has been part of Zentek's history since before I arrived on December 1," said Moe Jiwan, CEO of Zentek. "The Court's decision speaks for itself. What matters now is execution - on Albany, on ZenGUARD™, on Triera, and on building the foundation this company deserves. We move forward."
