Key Terms

2 terms

standing offer regulatory

"it has been awarded a Government of Canada standing offer to supply"

Standing offer is a pre-arranged agreement in which a buyer (often a government or large organization) and a supplier agree on prices, delivery terms, and conditions for goods or services to be supplied over a set period, while actual orders are placed later as needs arise and no specific quantity is guaranteed. For investors, it signals an approved, on-call sales channel and potential recurring work—like a store keeping a vendor on speed dial to restock—providing visibility into future demand without promising firm revenue.

merv 13 technical

"standard MERV 13 pleated filters it replaced"

MERV 13 is a common rating for air filters that measures how well the filter captures tiny particles such as dust, pollen, smoke and some respiratory droplets—think of it as a finer kitchen strainer that traps much smaller crumbs. For investors, MERV 13 matters because upgrading or maintaining these filters affects building operating costs, tenant health and comfort, regulatory compliance and capital spending, all of which can influence property value, occupancy and liability risk.

Zentek to supply HVAC filters to federal facilities in the National Capital Region as ZenGUARD(TM) Enhanced Air Filters remain available to all federal departments through the Pathway to Commercialization source list

Guelph, Ontario--(Newsfile Corp. - August 20, 2026) - Zentek Ltd. (TSXV: ZEN) (NASDAQ: ZTEK) ("Zentek" or the "Company") announces that it 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. Awarded through a competitive open-bidding process, the standing offer establishes pre-arranged pricing and terms under which federal departments may issue call-ups as requirements arise, runs from August 19, 2026, to August 18, 2027, and carries a maximum published value of CAD $348,666.84.

Management Commentary

"This standing offer expands Zentek's ability to serve the Government of Canada and reflects our commitment to being a reliable indoor air quality partner," said Moe Jiwan, Chief Executive Officer of Zentek. "Federal departments can now source our filtration products through this standing offer, while ZenGUARD™ Enhanced Air Filters remain available government-wide through the Pathway to Commercialization source list. Compared with denser filters commonly used to control infectious aerosols, ZenGUARD™ Enhanced Air Filters have demonstrated improved aerosol filtration without increased airflow resistance, offering the potential for lower energy use, fewer filter changes and less landfill waste."¹

Development on Demand

Zentek's Development on Demand model is straightforward: identify an opportunity, apply deep materials science, secure the intellectual property, and commercialize. ZenGUARD™ Enhanced Air Filters are a clear example of that model in action.

Zentek developed and patented ZenGUARD™ for air filtration and had it tested at the National Research Council of Canada ("NRC"). Testing in a purpose-built simulated classroom demonstrated approximately a fivefold improvement in aerosol filtration efficiency over an untreated filter, with no increase in pressure drop or energy consumption. The technology was then evaluated in a real-world setting. A three-month pilot at McKinnon Park Secondary School with the Grand Erie District School Board delivered 22% lower fan energy compared to the standard MERV 13 pleated filters it replaced, along with a substantially longer projected service life.¹

ZenGUARD™ Enhanced Air Filters deliver four operational outcomes:

• Safer indoor air

• Lower HVAC energy consumption and associated emissions

• Longer service intervals that reduce total cost of ownership

• Less waste sent to the landfill

Available Now to Every Federal Department

In May 2026, Innovative Solutions Canada ("ISC") added ZenGUARD™ Enhanced Air Filters to its Pathway to Commercialization ("PTC") source list. This establishes Zentek as an exclusive potential supplier within the PTC framework to the Government of Canada for a three-year period, during which any federal department or agency may purchase ZenGUARD™ Enhanced Air Filters directly, without a competitive procurement process.² Inclusion on the PTC source list does not guarantee a minimum number of orders or contracts, and procurement decisions remain at the discretion of individual federal departments and agencies.

This is a separate pathway from the standing offer announced today, and it is open now. A department that wants longer filter service life, lower fan energy, and better aerosol control can act on it immediately. Fewer changeouts and lower energy consumption reduce the operating cost of federal real property, and longer service intervals reduce operational waste, contributing to the federal target of diverting at least 75 percent of operational waste from landfills by 2030.³

Independently validated by the NRC and documented in three peer-reviewed ASHRAE publications. Manufactured in Canada, ZenGUARD™ Enhanced Air Filters deliver all four outcomes in a single drop-in product.
