Zentek Provides Update on Nasdaq Listing

Guelph, Ontario--(Newsfile Corp. - August 28, 2026) - Zentek Ltd. (TSXV: ZEN) (NASDAQ: ZTEK) ("Zentek" or the "Company"), today announces that its common shares will transition from trading on The Nasdaq Capital Market to the OTC Markets Group on Tuesday, September 2, 2026.

Zentek intends to request a hearing from Nasdaq to appeal the delisting determination.

The Company's common shares continue to trade on the TSX Venture Exchange under the symbol ZEN. The TSX Venture Exchange is the Company's primary listing and is unaffected by this determination. Shareholders are not required to take any action.
