Zentek Ltd. ("Zentek" or the "Company") (Nasdaq: ZTEK; TSX-V: ZEN), an intellectual property development and commercialization company and DCL Supply Ltd. ("DCL Supply"), a private Heating, Ventilation and Air Conditioning ("HVAC") master product distributor are pleased to announce that they have entered into a distribution agreement effective March 19^th, 2024, for an initial one-year term, and which automatically renews for subsequent one-year terms unless 90 days' notice is given by either party prior to renewal. The initial product to be distributed will be ZenGUARD Enhanced Air Filters for the HVAC market, subject to the assessment by the Health Canada Pesticide Management Regulatory Agency for registration under the Pest Control Products Act, which is ongoing. Subject to such registration, this agreement would allow DCL Supply to distribute ZenGUARD Enhanced Air Filters through its extensive distributor network serving numerous industrial, commercial and institutional clients within and across Canada.

DCL Supply Ltd.

DCL Supply serves many leading HVAC distributors across Canada and has a strong reputation for being a reliable and knowledgeable partner. For over 40 years, DCL Supply has demonstrated its commitment to service excellence and providing high quality, innovative and labour-saving brands to its clients.

"Creating healthier indoor spaces while reducing HVAC system maintenance costs is extremely important. To best accomplish this, we believe simple solutions that work with existing HVAC systems to control infectious aerosols will be most effective," remarked Greg Fenton, CEO of Zentek. "Our aim is to accomplish this without significantly increasing energy consumption and emissions. We are encouraged to see organizations in the HVAC space, like DCL Supply, that share our conviction on the importance of this balance, and we look forward to working with them in the months ahead."

"DCL Supply has been helping serve the HVAC needs of numerous industrial, institutional, and commercial clients for over 40 years. A key part of this is identifying and bringing forward new, innovative products for our distributor partners that add value for end users." said Michael Breault, Director of Sourcing and Business Development of DCL Supply. "Many property managers have shifted to using air filters with a higher level of mechanical filtration to capture more viral particles to help keep people safe. With the potential to not rely solely on a high level of mechanical filtration to accomplish this, we can improve indoor air quality while requiring fewer filter changes and reducing labour costs. This value proposition is a natural complement to the other solutions we provide to our clients – and also aligns closely with our commitment to bring forward labour-saving brands to our distributor network."

The ZenGUARD Enhanced Air Filter product is currently being assessed for registration under the Pest Control Products Act (Canada).

It cannot be manufactured, imported, distributed, or used in Canada at this time, unless explicit authorization has been obtained from Health Canada to use this product for the purpose of conducting research under the Pest Control Products Regulations.
