(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.

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.

Zentek has applied to seek approval for its common shares to be quoted on the OTCQX Best Market, the premier tier operated by the OTC Markets Group.

The transition of trading onto the OTC Markets Group is not expected to result in material impacts to Zentek's business or operations.
