ZENTEK ANNOUNCE STRATEGIC PARTNERSHIP WITH FILTRATION SOLUTIONS INDUSTRIAL CO. TO MANUFACTURE AND DISTRIBUTE GRAPHENE-ENHANCED HVAC FILTERS

Zentek Ltd. has signed a collaboration agreement effective April 11, 2025, with Filtration Solutions Industrial Co. (FSCO), a leading Saudi-based manufacturer and distributor of air filtration products, to manufacture and distribute ZenGuard enhanced air filters across the Gulf Cooperation Council (GCC) region.

Under the terms of the agreement, Zentek will supply FSCO with HVAC filter media coated with its proprietary graphene-silver-based ZenGuard technology -- known for its ability to significantly increase viral filtration efficiency. FSCO will produce ZenGuard enhanced air filters that will be marketed and distributed under Zentek's branding throughout the GCC, including Saudi Arabia, the United Arab Emirates, Kuwait, Qatar, Bahrain and Oman, with the net revenue generated from sales of the products shared between Zentek and FSCO. The term of the agreement is for three years, with additional renewal options.

This partnership is an exciting step forward in Zentek's global commercialization strategy," said Greg Fenton, chief executive officer of Zentek. "Demand for advanced materials like graphene -- and sustainable technologies like ZenGuard enhanced air filters -- is growing in the Gulf region, and we are proud to help meet this demand with a strong local partner like FSCO. Like Canada, we look forward to improving indoor air quality in buildings, while reducing operating costs, carbon emissions and waste."

"We are proud to partner with Zentek to bring next-generation air filtration solutions to our region," said Ahmad Al-Mahayni, deputy chief executive officer of FSCO. "ZenGuard aligns perfectly with the GCC's increasing focus on health, energy efficiency and advanced materials. This partnership allows us to deliver a premium product that supports those goals."

The announcement comes amid rising interest in graphene-based technologies across the GCC and aligns with the region's strategic vision of investing significantly to become a global hub for advanced materials and manufacturing -- an ambition highlighted in initiatives like the "Made in Saudi Program," "Operation 300 Billion" and "Make it in the Emirates." Graphene, in particular, is increasingly recognized for its potential in clean tech, electronics, energy storage and health care applications.

Air quality and building decarbonization are critical priorities in both public and private sectors throughout the region. Given the unique ability for ZenGuard enhanced air filters to improve indoor air quality and reduce emissions, Zentek will be presenting "HVAC Energy and CO2Eq Savings with Silver-Graphene Oxide Coated Filters" at the ASHRAE International Conference on Energy and Indoor Environment for Hot Climates in Doha, Qatar on April 23 to April 24, 2025.

ZenGuard enhanced air filters respond directly to this demand, offering:

• Improved viral filtration efficiency;
• Lower energy consumption due to reduced pressure drop;
• Cost-effective protection for high-traffic public buildings, health care, education and commercial facilities;
• Ability to control infectious aerosol in buildings where HVAC units cannot accommodate more dense filters.
