ZENTEK ISSUES SHAREHOLDER LETTER OUTLINING STRATEGIC RESET AND FOCUSED GROWTH PLAN

Zentek Ltd. has issued a letter to shareholders outlining a strategic reset focused on capital discipline, sharper execution and advancing a smaller number of core platforms with clear paths to value creation.

In the letter, Moe Jiwan, Zentek's chief executive officer, outlines the company's decision to narrow its focus to three core platforms: Albany Graphite, ZenGUARD and Triera. Each will be managed against defined milestones, capital allocation criteria and a 24-month road map. Other non-core initiatives have been paused or are being wound down to preserve capital and management focus.

The shareholder letter also details actions under way to reduce the company's cost base and better align spending with near-term priorities. These actions include work force and facility optimization, tighter controls on corporate spending, and a more disciplined approach to capital allocation. Future capital raises will be linked to specific milestones rather than open-ended development programs. As part of this reset, the company announces the departure of its chief science officer, Colin van der Kuur. The responsibilities of the chief science officer role have been redistributed across the existing technical leadership team.

"This reset is about protecting and rebuilding shareholder value," said Mr. Jiwan. "We are confident we have the right technical expertise and operating team in place to execute against our priorities, advance our core platforms and hold ourselves accountable to clear milestones and timelines."

The letter also outlines how each of the three core platforms will be advanced, how the company is aligning its research and development efforts to support those priorities, the company's approach to future financing, and new standards for transparency and reporting, including clearer segment-level financial disclosure and milestone tracking. The full shareholder letter is available on the Zentek website and on SEDAR+, and has been distributed directly to shareholders where an e-mail address is available.
