NAPLES, FL, August 22, 2025 – Rain Enhancement
Technologies Holdco, Inc. (Nasdaq: RAIN) (the “Company”) announced today that it received a notice (the “Notice”)
on August 19, 2025 from the Listing Qualifications Staff (“Staff”) of the Nasdaq Stock Market LLC (“Nasdaq”) notifying
the Company that it has not regained compliance with Nasdaq Listing Rule 5450(b)(2)(A), requiring the Company to maintain a market value
of listed securities of at least $50 million, and Nasdaq Listing Rule 5450(b)(2)(B), requiring the Company to maintain a market value
of publicly held shares of at least $15 million. The Notice provides that the Company has until 4:00 p.m. Eastern Time on August 26, 2025
to appeal the Staff’s delisting determination.

Pursuant to the Notice, unless the Company timely
requests a hearing from the Nasdaq Hearing Panel (the “Panel”), the Company’s securities will be subject to suspension
and delisting from the Nasdaq Global Market at the opening of business on August 28, 2025. The Company submitted its timely request for
a hearing before the Panel on August 21, 2025 to request additional time to regain compliance with Nasdaq listing rules. The Company expects
that its hearing request will result in a stay of any suspension or delisting action pending the hearing. At the hearing, the Company
intends to present its plan to achieve compliance with all applicable listing criteria; however, there can be no assurance that the Panel
will grant the Company’s request for continued listing or that the Company will be able to achieve compliance within any period
of time that may be granted by the Panel. The Company is considering all options available to it to regain compliance with all applicable
listing rules.
