Zentek sets Sept. 2 shift to OTCQX from Nasdaq

Starting Sept. 2, 2026, Zentek expects trading on the Nasdaq Capital Market to be suspended, even though shareholders aren’t required to take any action.

Rhea-AI Filing Summary

Zentek Ltd. (ZTEK) reports that its common shares have been approved for trading on the OTCQX Best Market, with trading expected to begin under the U.S. symbol ZTEKF on September 2, 2026. On the same date, trading of its common shares on the Nasdaq Capital Market is expected to be suspended.

Negative

• Trading on the Nasdaq Capital Market is expected to be suspended on September 2, 2026, following a Nasdaq delisting determination, and there is no assurance the common shares will be relisted or that Zentek will regain compliance with any Nasdaq listing requirement.

Filing Explained

OTCQX Best Market market

"its common shares have been approved for trading on the OTCQX Best Market"

OTCQX Best Market is the top tier of an over‑the‑counter (OTC) trading platform where companies voluntarily meet higher disclosure and governance standards than typical OTC listings. For investors, it signals relatively better transparency and oversight—think of it as a premium section of a flea market where sellers show more paperwork—yet these stocks still carry more liquidity and regulatory risk than listings on major national exchanges.

Nasdaq Capital Market market

"Trading of the Company's common shares on The Nasdaq Capital Market is expected"

The Nasdaq Capital Market is a platform where smaller, emerging companies can list their shares for trading by investors. It provides these companies with access to funding and visibility, helping them grow, much like a local marketplace where new vendors can introduce their products to potential customers. For investors, it offers opportunities to discover early-stage companies with growth potential.

TSX Venture Exchange market

"The Company's common shares continue to trade on the TSX Venture Exchange"

A junior stock exchange in Canada where smaller, early-stage companies list shares to raise capital and gain public visibility. Think of it as a farmers’ market for young businesses: it offers investors a chance to buy into fast-growing but higher-risk ventures, with looser listing rules and typically lower liquidity than major exchanges. It matters because performance and financing on this exchange can signal growth prospects or risk for investors.

forward-looking information regulatory

"This news release contains "forward-looking information" within the meaning"

Forward-looking information are predictions, plans, estimates or expectations about a company’s future performance, results or events, such as sales forecasts, project timelines, or anticipated costs. It matters to investors because these statements guide expectations but rely on assumptions and uncertain factors—like a weather forecast for a business—so investors should treat them as informed guesses rather than guarantees and consider the risks and possible changes behind the numbers.

critical minerals technical

"advancing a portfolio of graphene-enabled and advanced material technologies across clean air, next-generation materials, and critical minerals"

Materials needed to build modern technologies—like batteries, electronics, renewable energy systems and defense equipment—that have few easy substitutes and often come from a small number of countries or mines. Investors care because their supply can be disrupted, expensive or slow to increase, which affects the cost, availability and growth prospects of companies and industries that rely on them; think of them as critical spare parts for the global economy.
