Zentek Exits Nasdaq, Opens on OTCQX Under 'ZTEKF' — TSX-V Holds as Primary Listing

Zentek Ltd. lost its Nasdaq Capital Market listing on September 1, 2026 and began trading on the OTCQX Best Market the following morning — a one-day operational handoff documented in the company's September 1, 2026 announcement.

The sequence: Nasdaq issued a delisting determination after Zentek failed to meet the exchange's minimum bid price requirement of US$1.00 per share across both available compliance periods. On the same day — September 1, 2026 — OTCQX approval was announced, and shares opened under the symbol "ZTEKF" at the start of trading on September 2, 2026. Zentek said it intends to request a hearing to appeal the Nasdaq determination, but noted the appeal will not stay the suspension of trading on Nasdaq.

The company applied for expedited review, meaning approval was in hand before the first day of quotation. Shares went straight to OTCQX rather than sitting on a lower tier during processing.

Zentek's common shares continue to trade on the TSX Venture Exchange under the symbol ZEN. The company's September 1 release describes the TSX-V as the primary listing and states it is unaffected by the Nasdaq situation. For U.S. investors, OTCQX qualification for companies listed on a qualified international exchange allows the use of home-market reporting to satisfy U.S. disclosure requirements. Zentek said it expects no material impact on its operations.

The company describes itself as a Canadian intellectual property development and commercialization company with three platforms: Albany Graphite, a graphite deposit that has demonstrated ultra-high purity in bench scale purification testwork; ZenGUARD™, a graphene-enabled clean air technology; and Triera, built on a 20-year exclusive, worldwide, royalty-bearing license with McMaster University covering aptamer applications. The company also holds a growing patent portfolio. None of that pipeline changes with the exchange shift.

The macro backdrop for the week ending September 19, 2026 was not hospitable to smaller-cap names. The Federal Reserve on September 16, 2026 unanimously voted to raise the benchmark rate 25 basis points to a range of 3.75–4.00%, the first hike since 2023. The ten-year Treasury yield closed at 4.998%, up 1.03% on the day. The Russell 2000 lost 0.53% on the week — small- and mid-caps lagged while large-cap growth held. The S&P 500 added 0.17% to 7,650.50 and the Nasdaq Composite gained 0.39% to 26,522.54, per the Rio Times global economy briefing for the week ended September 19, 2026.

OTCQX carries its own standards for financial condition, disclosure, and current information, and quotation there is not guaranteed indefinitely, per the company's September 1, 2026 announcement. Zentek has not disclosed a cash position or share count in the primary release, and no summary metrics from its Q2 2026 financials appear in available sources.

The week of September 22–26 brings China loan prime rates on Monday, flash PMIs Wednesday, and Banxico Thursday. Quarter-end window dressing could add volatility, per the Rio Times macro briefing for the week ended September 19, 2026. For Zentek specifically, the next disclosed milestone is the outcome of its Nasdaq delisting appeal — a hearing it has said it will request, with no timeline yet announced.
