ZENTEK ANNOUNCES AGREEMENT WITH RSK ENVIRONMENT LIMITED TO EXPAND INTERNATIONAL REACH OF ZENGUARD ENHANCED AIR FILTERS

Zentek Ltd. executed an agency agreement with RSK Environment Ltd., a global environmental consulting, engineering and technical service business, headquartered in the United Kingdom, on May 7, 2025. This agreement enables RSK to act as Zentek's authorized facilitator for marketing and promoting its ZenGuard enhanced air filters in more than 20 countries.

Under the agreement, RSK will support Zentek's international growth by identifying and developing sales opportunities for ZenGuard enhanced air filters in key global markets, including the Gulf Cooperation Council region. Zentek will retain full responsibility for manufacturing and fulfilment while compensating RSK with a fixed commission on sales generated within the designated territories. The term of the agreement is for three years, with additional renewal options.

"We're excited to partner with a global environmental leader like RSK," said Greg Fenton, chief executive officer at Zentek. "We believe their expertise and network will help accelerate adoption of ZenGuard enhanced air filters in markets where energy efficiency, indoor air quality and sustainability are becoming mission critical."

"We are happy to embark on a partnership with Zentek to help bring ZenGuard enhanced air filters to the GCC region and a number of other countries where we operate," said Ian Goodacre, director at RSK. "Many of our clients are focused on finding sustainability solutions that can be implemented quickly and easily -- and we believe using ZenGuard enhanced air filters to improve indoor air quality while reducing energy consumption can meet this growing need."

In addition to Zentek's agreement with Saudi-based Filtration Solutions Industrial Co. and with Levidian to accelerate the rollout of ZenGuard enhanced air filters and other graphene-enhanced products within the GCC region, this agreement is expected to further support Zentek's international sales efforts by aligning advanced heating, ventilation and air conditioning filtration solutions with regional sustainability and infrastructure goals.
