Insights

Equity listings and market-structure analyst

Nasdaq minimum bid price deficiency notice introduces listing-compliance risk.

Zentek Ltd. disclosed that it received a Nasdaq notification about a minimum bid price deficiency, a standard step when a company’s share price falls below the exchange’s required threshold. This does not immediately remove the listing but flags a compliance issue.

Such notifications typically start a defined cure or compliance period, though specific terms are not detailed here. The inclusion of this notice in a formal report highlights that Zentek’s Nasdaq listing status now depends on addressing the minimum bid price requirement.
