Entry into Material Agreement 

On June 11, 2026, ReTo Eco-Solutions, Inc (the “Company”) entered into a securities purchase agreement (the “Securities Purchase Agreement”) with several purchasers (the “Purchasers”) for a private placement (the “PIPE”) of (i) 2,968,747 Class A shares with no par value (the “Shares”) and (ii) 5,937,494 warrants (the “Warrants”, and the Shares underlying such Warrants, the “Warrant Shares”), with each Warrant to purchase one Warrant Share, at an combined price of $1.28 per share and two associated Warrants.

The exercise price to purchase each Warrant Share is at an initial exercise price of $1.28 per share (“Initial Exercise Price”), subject to adjustment, including cashless exercise and exercise reset, however, in no event shall the exercise price be lower than $0.10 per share and the maximum amount of Shares issuable upon exercise of the Warrants will not exceed 5,937,494 Shares. The Warrants are exercisable upon issuance and will expire five years from their Initial Exercise Date. Pursuant to the Securities Purchase Agreement, on the seventh calendar days after the issuance date (the “Initial Exercise Date”) of the Warrants, the exercise price of the Warrants shall be adjusted to 20% of the Initial Exercise Price. In addition, starting on the tenth calendar days following the Initial Exercise Date, the holder of the Warrants may alternatively exchange all, or any part, of the Warrants into such aggregate number of Shares equal to the product of (x) 0.9 and (y) such aggregate number of Warrant Shares underlying such portion of the Warrants to be exercised.

In addition, the Company and certain Purchasers (the “Lenders”) have entered into a loan agreement (the “Loan Agreement”) dated May 21, 2026, which the Lenders agreed to lend to the Company an aggregate principal sum of US$3,800,000, with a term of one month (the “Debt”). As the consideration of the PIPE, the Lenders have subsequently signed a surrender letter dated June 11, 2026 (the “Surrender Letter”) to surrender and forever relinquish any and all the rights, claims, and interests that he/she has (or may have) to the repayment of the Debt under the Loan Agreement in exchange for the Shares being issued under the PIPE. This surrender includes any accrued but unpaid interest, if applicable, and any other amounts due to the Lenders under the Loan Agreement.

The PIPE is expected to close on June 12, 2026. The Company intends to use the net proceeds for working capital and general corporate purposes.

The Shares and Warrants were issued in reliance on Section 4(a)(2) and/or Regulation D promulgated under the Securities Act of 1933, as amended.

The foregoing description of the Warrants and the Securities Purchase Agreement do not purport to be complete and are qualified in their entirety by reference to the full text of the form of Securities Purchase Agreement, form of Securities Purchase Agreement and form of Surrender Letter, which are attached hereto as Exhibits 4.1, 10.1 and 10.2 and are incorporated herein by reference.
