Dennis P. Calvert, the company's President and CEO, said, "Company-wide revenues are rising again. Through Q3, we have already surpassed last year's annual revenues by 34%, with another quarter to go. Pooph pet-odor product sales are climbing steadily as our partners continue to expand retail presence around the country."

He continued, "Over the summer, our PFAS team has been approached by a broad base of prospective customers in diverse industries, including municipalities, government agencies, drinking water systems, firefighting foam projects, wastewater entities, and industrial facilities. The excitement about our PFAS collection and destruction solution has been highly validating to our value proposition to the marketplace. Our engineers have commenced work on a project to remove PFAS from a municipal drinking water supply in New Jersey, and we look forward to sharing more details as they come available."

On the topic of the company's new safe, long-lasting battery technology, Mr. Calvert said, "Finally, I'm happy to report that substantial progress has been made in the construction of our Oak Ridge, Tennessee manufacturing facility for the prototypes of our safe, longer-lasting long duration energy storage (LDES) battery technology. We hope to have batteries built and being tested by year's end."
