Item 3.01 Notice of Delisting or Failure to Satisfy a Continued Listing Rule or Standard; Transfer of Listing.

On February 18, 2026, Rain Enhancement Technologies Holdco, Inc. (the “Company”) received written notice (the “Notice”) from the Listing Qualifications Staff of the Nasdaq Stock Market LLC (“Nasdaq”) which notified the Company that, for the 30 consecutive business days ended February 17, 2026, the Company’s market value of listed securities (“MVLS”) closed below the $35,000,000 threshold required for continued listing on the Nasdaq Capital Market under Nasdaq Listing Rule 5550(b)(2) (the “MVLS Rule”).

In accordance with Nasdaq listing rule 5810(c)(3)(C), the Company has 180 calendar days, or until August 17, 2026 (the “MVLS Compliance Period”), to regain compliance with the MVLS Rule. The Notice notes that to regain compliance, the Company’s MVLS must close at or above $35 million for a minimum of ten consecutive business days during the MVLS Compliance Period, upon which Nasdaq will provide written confirmation of compliance and the matter will be closed. If the Company does not regain compliance by the end of the MVLS Compliance Period, Nasdaq staff will provide written notice to the Company that its securities are subject to delisting. At that time, the Company may appeal any such delisting determination to a hearings panel.

The Notice is a notification of deficiency, not of imminent delisting, and has no immediate effect on the listing of the Company’s securities. The Company’s common stock and warrants continue to trade on Nasdaq under the symbols “RAIN” and “RAINW”, respectively.

The Company intends to actively monitor the Company’s MVLS between now and August 17, 2026, and may, if appropriate, evaluate available options to resolve the deficiency and regain compliance with the MVLS Rule. While the Company is exercising diligent efforts to maintain the listing of its securities on Nasdaq, there can be no assurance that the Company will be able to regain or maintain compliance with Nasdaq listing standards.

Forward Looking Statements

Certain information contained in this Current Report on Form 8-K consists of forward-looking statements that involve risks, uncertainties and assumptions that are difficult to predict. Words such as “must,” “will,” “may,” “intends,” and similar expressions, or the use of future tense, identify forward-looking statements, but their absence does not mean that a statement is not forward-looking. Such forward-looking statements are not guarantees of performance and actual actions or events could differ materially from those contained in such statements. For example, there can be no assurance that the Company will regain compliance with the MVLS Rule during the MVLS Compliance Period. Additional factors that could cause actual results to differ from the forward-looking statements herein include potential adverse effects on the Company’s business related to the disclosures made in this Current Report on Form 8-K, or the initiation of new legal proceedings, volatility of the Company’s stock price, and the other risk factors discussed under the caption “Risk Factors” in the Company’s Annual Report on Form 10-K for the year ended December 31, 2024 and the Company’s other filings with the Securities and Exchange Commission. The forward-looking statements contained in this Current Report on Form 8-K speak only as of the date of this report and the Company undertakes no obligation to publicly update any forward-looking statements to reflect changes in information, events or circumstances after the date of this report, unless required by law.
