Zentek (TSXV: ZEN, NASDAQ: ZTEK) announced that its common shares are expected to transition from trading on the Nasdaq Capital Market to the OTC Markets Group on Tuesday, September 2, 2026, following a Nasdaq notice that its shares will be delisted for not meeting the minimum bid price requirement.
Zentek plans to request a Nasdaq hearing to appeal the delisting, but the hearing will not prevent trading suspension on Nasdaq, which is expected at the open on September 2, 2026. The company’s common shares will continue to trade on the TSX Venture Exchange, its primary listing, under symbol ZEN. Zentek has applied to have its shares quoted on the OTCQX Best Market and, according to the company, does not expect the transition to OTC Markets to materially impact its business or operations.
Zentek (NASDAQ: ZTEK) has been awarded a Government of Canada standing offer to supply a range of HVAC filtration products, including ZenGUARD™ Enhanced Air Filters, to federal facilities in the National Capital Region. The competitively tendered agreement runs from August 19, 2026 to August 18, 2027, sets pre-arranged pricing and terms for departmental call-ups, and has a maximum published value of CAD $348,666.84.
Separately, ZenGUARD™ air filters were added in May 2026 to Innovative Solutions Canada’s Pathway to Commercialization source list, making Zentek an exclusive potential supplier of these filters to federal departments and agencies for three years, though with no guaranteed volume of orders.
Zentek (NASDAQ: ZTEK, TSXV: ZEN) filed a provisional patent application with the U.S. Patent and Trademark Office for ZEN-EMI-01, a water-based electromagnetic interference (EMI) shielding coating made from purified graphite sourced from its Albany deposit. The filing establishes a priority date for an absorption-based EMI shielding platform that dissipates electromagnetic energy as heat within a thin coating rather than reflecting it toward neighbouring systems.
Internal laboratory tests indicated that a layer roughly the thickness of two sheets of paper significantly reduced a band of microwave frequencies commonly used in radar and satellite communications, with absorption accounting for most of the shielding. These preliminary results were generated at Zentek’s Guelph facility, have not been independently verified, and ZEN-EMI-01 is at the laboratory stage with no assurance of commercialization or patent grant. The development plan over the next twelve months includes third‑party standardized shielding measurements, formulation optimization, application and durability testing with prospective partners, and process scale‑up, while Zentek highlights vertical integration from its Albany graphite resource.
Zentek (NASDAQ: ZTEK) released a new NI 43‑101 Preliminary Economic Assessment for its 100%-owned Albany Graphite Project in Northern Ontario, outlining an integrated mine‑to‑purification operation targeting ultra‑high‑purity graphite for nuclear, defence and other strategic markets.
The PEA, prepared by Micon, estimates an after‑tax NPV (5%) of US$3.85 billion, after‑tax IRR of 27.4%, and a discounted after‑tax payback of 4.4 years, based on initial capital of US$817 million and total life‑of‑mine capital of US$1.98 billion. The 30‑year production period contemplates processing 25.9 Mt of mill feed grading 3.9% Cg to produce about 30,000 t/y of finished ultra‑high‑purity graphite at an average realized price of US$23,485/t, yielding average annual net revenue of US$639.3 million.
The flowsheet uses flotation and fluidized bed reactor thermal purification, with bench‑scale tests achieving 99.9992% carbon and 2.60 ppm boron equivalent without hydrofluoric acid. Life‑of‑mine operating costs are projected at US$6.65 billion, or US$7,989/t of finished product. The PEA is preliminary and includes inferred resources, with no assurance of economic viability.

Zentek highlights that Atrium is at arm’s length and holds no securities. Management notes the coverage will address the Albany Graphite Project, now advancing toward a Preliminary Economic Assessment targeted for completion this summer, and the ZenGUARD air filtration platform, which is already generating commercial revenue.
Zentek (NASDAQ: ZTEK) announced that partner Quality Filters completed a validation and qualification program for ZenGUARD™ Enhanced Air Filtration Media and placed its first U.S. commercial order for 244 rolls. This moves ZenGUARD from pilot evaluation to commercial production and U.S. market launch activities.
Zentek (NASDAQ: ZTEK) has secured a pathway to sell its ZenGUARD(TM) Enhanced Air Filtration Media in the U.S. through an exclusive license with Applied Silver for EPA-registered silver technology.
