Item 1.01 Entry into a Material Definitive Agreement.

Effective as of March 31, 2026, Rain Enhancement Technologies Holdco,

Inc. (the “Company”) and RHY Management LLC, an affiliate of Harry You, the Company’s chairman and a beneficial owner

of more than 10% of the Company’s Class A common stock and Class B common stock, (“RHY”) entered into an amendment (the

“Loan Agreement Amendment”) to that certain Loan Agreement between RHY and the Company, dated as of December 30, 2024 (the

“Loan Agreement”), increasing the amount that could be borrowed by the Company under the line of credit (the “LOC”)

pursuant to the Loan Agreement from $7,000,000 to $10,000,000.

The foregoing description does not purport to be complete and is qualified

in its entirety by reference to the full text of the Loan Agreement Amendment. A copy of the Loan Agreement Amendment is filed as Exhibit

10.1 to this Current Report on Form 8-K and incorporated herein by reference.

Item 2.03 Creation of a Direct Financial Obligation or an Obligation

under an Off-Balance Sheet Arrangement of a Registrant.

The information relating to the Loan Agreement Amendment contained

in Item 1.01 of this Current Report on Form 8-K is incorporated by reference into this Item 2.03 to the extent required herein.

As previously disclosed, the LOC bears interest at the greater of 5%

per annum or the applicable IRS short-term rate in the month of each drawdown (“Interest Rate”), payable quarterly in arrears.

If a quarterly payment is missed, the loan balance increases by an amount equal to the principal multiplied by the Default Rate (as defined

below). If an event of default has occurred and is continuing, then upon written notice by RHY to the Company, the outstanding principal

balance and any unpaid accrued interest will accrue interest at 2% above the Interest Rate (the “Default Rate”).
