Burnaby, British Columbia--(Newsfile Corp. - September 8, 2025) - Aether Catalyst Solutions, Inc. (CSE: ATHR) (FSE: 2QZ) (OTCBB: ATHHF) ("ATHR" or the "Company") - Aether is pleased to announce results of the Urban Small Motors Emissions Abatement Project (USMEAP) with the City of Burnaby during its fifth year.

Hours are expected to accumulate slowly through the rest of the summer as the seasonal heat and low rainfall cause grass growth to slow. Usage typically picks back up in the fall as temperatures cool and rainfall levels increase. The catalysts continue to perform very well. NOx conversion of 100% indicates that we are unable to measure any NO leaving the muffler after it passes through our catalyst.

Exhaust emissions standards are set by regulatory bodies like the EPA, ECCC or CARB. They define specific numerical targets that a particular class of engine must adhere to for a particular duration. Most motors of the size used on this equipment are expected to maintain their emissions standards for 1000 hours.

"Field tests provide powerful data," says Aether COO Taylor Procyk, "Not only do they provide technical nuance that can only come from exposure to a real environment of use, but they also provide much more convincing data for potential partners. Our field test has enabled us to study the SORE catalyst for approximately 500 hours now, and the unfaltering performance is making a strong case for the technology in this application."

Additionally, the Company is pleased to announce that it has engaged 1502656 BC Ltd.to provide investor relations services to the Company for an initial period of 6 months. Under the terms of the engagement, 1502656 BC Ltd. has been paid $300,000.
