ZENTEK ENGAGES ATRIUM RESEARCH CORPORATION FOR COMPANY-SPONSORED RESEARCH COVERAGE

Zentek Ltd. has engaged Atrium Research Corp., a company-sponsored research firm, to provide research coverage of the company.

Atrium will publish research reports on Zentek based on publicly available information, industry data and discussions with management. Atrium will also host two recorded interviews with Zentek's management team to discuss the company's business and strategy. In exchange for its research services, Atrium will receive cash compensation of $13,200 per quarter. The services will be provided for a term of 18 months beginning July 15, 2026. At the end of the term, the agreement will remain in place and extend on a quarter-to-quarter basis at $13,200 per quarter, unless otherwise agreed by the parties or terminated by either party. This engagement is subject to TSX Venture Exchange approval.

Atrium and the company are arm's-length parties, and neither Atrium nor its insiders hold any shares or options to purchase shares in the issued and outstanding capital of the company.

Management commentary

"Atrium's research coverage will provide investors with in-depth analysis of Zentek's business, including the Albany graphite project, which is currently advancing through a preliminary economic assessment targeted for completion this summer, and ZenGUARD, our air filtration technology platform, which is already generating commercial revenue. Albany graphite has been purified at bench scale to 5N, consistent with nuclear-grade specifications and defence markets that require that level of purity. As the PEA is completed and we advance our other initiatives, we believe access to well-researched coverage will help investors evaluate the company," said Mohammed (Moe) Jiwan, chief executive officer of Zentek.
