Burnaby, British Columbia--(Newsfile Corp. - May 20, 2025) - Aether Catalyst Solutions, Inc. (CSE: ATHR) ("Aether" or the "Company") is pleased to announce that the Company has closed a first tranche of its previously-disclosed non-brokered private placement (the "Offering") of units of the Company (each, a "Unit"). The tranche consisted of 10,095,332 Units at a price of $0.075 per Unit for aggregate gross proceeds of $757,150.

Each Unit consists of one common share in the capital of the Company (each, a "Share") and one-half of one common share purchase warrant (each whole warrant, a "Warrant"), with each Warrant entitling the holder thereof to acquire one additional Share at an exercise price of $0.15 per Share for a period of 18 months from the applicable closing date.

The tranche was completed pursuant to the listed issuer financing exemption under Part 5A of National Instrument 45-106 Prospectus Exemptions (the "LIFE Exemption") and, therefore, any securities issuable under the LIFE Exemption are not subject to a hold period in accordance with applicable Canadian securities laws. An offering document related to the Offering is available under the Company's profile at www.sedarplus.ca and on the Company's website www.aethercatalyst.com.

Each Finder's Warrant entitles the holder thereof to acquire one Share at an exercise price of $0.075 per Share for a period of 18 months from the date of issuance.

Both the Warrants and the Finder's Warrants are subject to acceleration such that if, during a period of 10 consecutive trading days prior to their respective expiry dates, the daily volume-weighted average trading price of the Shares on the Canadian Securities Exchange (the "CSE") or such other stock exchange where the majority of the trading volume occurs, exceeds $0.30 for each of those 10 consecutive days, the Company may, within 30 days of such an occurrence, give written notice to the holders of the Warrants and the Finder's Warrants that the securities will expire at 5:00 p.m. (Vancouver time) on the 30^th day following the giving of notice unless exercised by the holders prior to such date.
