Nasdaq grants Zentek (NASDAQ: ZTEK) 180-day minimum bid-price extension

Rhea-AI Filing Summary

Zentek Ltd. received a further 180‑day extension from Nasdaq to regain compliance with the exchange’s minimum $1.00 bid price requirement for continued listing. The new deadline to meet Nasdaq Listing Rule 5550(a)(2) is August 24, 2026.

The company’s shares will continue to trade on Nasdaq under the symbol “ZTEK” with no immediate impact on listing or trading status. To regain compliance, Zentek must maintain a closing bid price of at least $1.00 per share for a minimum of 10 consecutive business days on or before the new deadline.

Management plans to monitor the share price and consider available options to satisfy the requirement while continuing to advance its graphene-enabled advanced material technologies across healthcare, clean air and industrial applications.

Positive

• None.

Negative

• Nasdaq compliance risk remains: Zentek has only a 180‑day extension, until August 24, 2026, to achieve a closing bid of at least $1.00 for 10 consecutive business days, or its Nasdaq listing could be at risk under the exchange’s rules.

Insights

Equity markets and listing standards analyst

Nasdaq extension delays, but does not remove, Zentek’s listing risk.

Zentek has secured an additional 180 days, until August 24, 2026, to restore compliance with Nasdaq’s $1.00 minimum bid price rule. This keeps the shares trading under the symbol ZTEK without immediate listing consequences.

The key condition is maintaining a closing bid of at least $1.00 for 10 consecutive business days within the extension window. If this is not achieved, Nasdaq listing status could be at risk under the applicable rules, which would be a meaningful event for investors who value U.S. exchange liquidity.

Management indicates it will monitor the share price and consider available options, but the specific measures are not detailed here. The practical impact will hinge on whether Zentek can meet the 10‑day price test before August 24, 2026 under prevailing market conditions.
