Item 1.01.

Entry into a Material Definitive Agreement.

Indenture

On October 1, 2026, Solaris Energy Infrastructure, LLC (the “Issuer”), a subsidiary of Solaris Energy Infrastructure, Inc. (the “Company”), issued $1.25 billion aggregate principal amount of 7.000% Senior Notes due 2032 (the “Notes”) in a private placement (the “Offering”) conducted pursuant to Rule 144A and Regulation S under the Securities Act of 1933, as amended (the “Securities Act”). The Notes were issued at par for net proceeds of approximately $1,227.2 million, after deducting the initial purchasers’ discount and estimated offering expenses. The Issuer intends to use the net proceeds from the Offering for general corporate purposes, growth capital expenditures and to pay fees and expenses related to the Offering.

The Notes are governed by an Indenture, dated as of October 1, 2026 (the “Indenture”), by and among the Company, the Issuer, the subsidiary guarantors named therein (the “Subsidiary Guarantors”) and U.S. Bank Trust Company, National Association, as trustee (the “Trustee”). The Notes will mature on April 1, 2032, and interest on the Notes is payable semi-annually in arrears on each April 1 and October 1, commencing April 1, 2027, at a rate of 7.000% per annum. The Notes are unconditionally guaranteed on a senior unsecured basis by the Company and the Subsidiary Guarantors (the “Guarantees”). The Notes and the Guarantees (i) rank equally in right of payment with all existing and future senior indebtedness of the Issuer, the Company and the Subsidiary Guarantors, (ii) are structurally senior to the Company’s 4.75% Convertible Senior Notes due 2030 and 0.25% Convertible Senior Notes due 2031 (collectively, the “Convertible Notes”) to the extent of the Guarantees by the Subsidiary Guarantors and (iii) are senior in right of payment to the corresponding subordinated intercompany convertible notes issued by the Issuer to the Company in aggregate principal amounts equal to the outstanding amounts under the Convertible Notes.

Optional Redemption

At any time prior to April 1, 2029, the Issuer may on any one or more occasions redeem up to 40% of the aggregate principal amount of the Notes issued under the Indenture, in an amount not greater than the net cash proceeds of one or more equity offerings, at a redemption price of 107.000% of the principal amount plus accrued and unpaid interest, if any, to, but not including, the redemption date; provided that: (i) at least 50% of the aggregate principal amount of the Notes originally issued under the Indenture remains outstanding immediately after the occurrence of such redemption (excluding the Notes held by the Company and its subsidiaries); and (ii) the redemption occurs within 180 days of the date of the closing of such equity offering. In addition, at any time prior to April 1, 2029, the Issuer may on any one or more occasions redeem all or part of the Notes, at a redemption price equal to 100% of the principal amount of the Notes to be redeemed, plus an applicable make-whole premium and accrued and unpaid interest, if any, to, but not including, the redemption date.

On and after April 1, 2029, the Issuer may on any one or more occasions redeem all or a part of the Notes, at the redemption prices (expressed as percentages of principal amount of the Notes to be redeemed) set forth below, plus accrued and unpaid interest, if any, on the Notes redeemed, to, but not including, the applicable redemption date, if redeemed during the twelve-month period beginning on April 1 of the years indicated below:

Change of Control

If a Change of Control Triggering Event (as defined in the Indenture) occurs, the Issuer will be required to offer to repurchase all or any part of the outstanding Notes in cash at a purchase price equal to 101% of the aggregate principal amount of the Notes repurchased, plus accrued and unpaid interest, if any, on the Notes repurchased to, but not including, the date of repurchase.

Certain Covenants

The Indenture contains covenants that, among other things and subject to certain exceptions, limit the Issuer’s ability and the ability of its restricted subsidiaries to: (i) incur or guarantee additional indebtedness or issue certain


preferred stock; (ii) pay dividends on capital stock or redeem, repurchase or retire its capital stock or subordinated indebtedness; (iii) transfer or sell assets; (iv) make investments; (v) create certain liens; (vi) enter into agreements that restrict dividends or other payments from its restricted subsidiaries; (vii) consolidate, merge or transfer all or substantially all of its assets; (viii) engage in transactions with affiliates; and (ix) create unrestricted subsidiaries.

Events of Default

The Indenture contains customary events of default, including, among other things, failure to make required payments, failure to comply with certain agreements or covenants, failure to pay or acceleration of certain other indebtedness, a guarantee being held unenforceable or invalid, certain events of bankruptcy and insolvency, and failure to pay certain judgments. An event of default under the Indenture will allow either the Trustee or the holders of at least 30% in aggregate principal amount of the then-outstanding Notes to accelerate the amounts due under the Notes.
