ZENTEK PROVIDES REGULATORY UPDATE FOR ZENGUARD ENHANCED AIR FILTERS

Zentek Ltd. has withdrawn its submission to the Health Canada Pest Management Regulatory Agency (PMRA) for its ZenGuard enhanced air filters. Based on feedback received from PMRA and continued analysis of the Canadian regulatory environment, the company believes there are other more cost-effective and timely pathways to bring ZenGuard enhanced air filters to market in Canada. The company has been evaluating and planning for these potential alternative options in parallel with the PMRA assessment process over the last several months and will now shift its focus to these other pathways.

"Our top priority as a company is ensuring we do everything we can to create value for our stakeholders as quickly and effectively as possible, which is why we are shifting our focus to pursue other pathways to market in Canada for ZenGuard enhanced air filters," said Greg Fenton, chief executive officer of Zentek.

"Importantly, we know that one of the biggest challenges facing society is climate change and building decarbonization. Buildings contribute nearly 40 per cent of global energy-related CO2 [carbon dioxide] emissions, and ZenGuard enhanced air filters are one of the only tools in the toolbox to help control infectious aerosols without significantly increasing energy consumption and emissions. The sooner we can bring ZenGuard enhanced air filters to market, the sooner we can do our part to help reduce emissions while keeping people safe indoors -- not only in Canada but globally as well."
