FOR IMMEDIATE RELEASE

ATI AIRTEST ANNOUNCES CLOSING OF NON-BROKERED PRIVATE PLACEMENT

Vancouver, BC, March 21, 2024 - ATI Airtest Technologies Inc. (TSXV: AAT, OTC: AATGF) ("ATI" or the "Company") announces that it has completed its previously announced non-brokered private placement (the "Financing"), as described in its press release of February 8, 2024 pursuant to which it has issued an aggregate of 19,977,600 units (each, a "Unit") at a price of $0.02 per Unit, for aggregate gross proceeds of $399,552.

Each Unit is comprised of one common share in the capital of the Company (each, a "Share") and one non-transferable share purchase warrant (each, a "Warrant"). Each Warrant will entitle the holder to purchase one additional Share in the capital of the Company (each, a "Warrant Share" and collectively with the Units, Shares and Warrants, the "Securities") for a period of 24 months from the closing date at an exercise price of $0.05 per Warrant Share, subject to the Acceleration Provision (as defined below). If the daily trading price of the Shares on the TSX Venture Exchange ("TSXV") (or such other exchange on which the Shares may be traded at such time) is $0.08 or greater per Share for ten (10) trading days (which do not need to be consecutive), the Company may accelerate the expiry date of the Warrants by giving notice via news release to the holders thereof and, in such case, the Warrants will expire on the thirtieth (30th) day after the date on which the news release is disseminated by ATI (the "Acceleration Provision").

The Company intends to use 100% of the proceeds from the Financing for general working capital purposes. No finder's fees were paid or compensation issued in connection with the Financing.

A certain insider of the Company indirectly subscribed for a total of 2,500,000 Units under the Financing, which is a "related party transaction" within the meaning of Multilateral Instrument 61-101 - Protection of Minority Security Holders in Special Transactions ("MI 61-101"). Accordingly, the subscription by the Insider and the issuances of the Securities thereunder are exempt from the valuation requirement of MI 61-101 by virtue of the exemption contained in section 5.5(b) as the Company's Shares are not listed on a specified market and from the minority shareholder approval requirements of MI 61-101 by virtue of the exemption contained in section 5.7(a) of MI 61-101 in that the fair market value of the consideration of the Securities issued to the related party did not exceed 25% of the Company's market capitalization.

The Securities issued under the Financing, and the Shares that may be issuable on exercise of the Warrants, are subject to a hold period expiring on July 22, 2024 pursuant to applicable securities laws and the policies of the TSXV.
