Item 1.01. Entry into a Material Definitive Agreement.

At-the-Market Offering Agreement

On March 28, 2025, MARA Holdings, Inc. (the “Company”) entered into an At The Market Offering Agreement (the “Agreement”) with Barclays Capital Inc., BMO Capital Markets Corp., BTIG, LLC, Cantor Fitzgerald & Co., Guggenheim Securities, LLC, H.C. Wainwright & Co., LLC and Mizuho Securities USA LLC in their capacities as agents (each, an “Agent” and together, the “Agents”) with respect to an at-the-market offering program under which the Company may offer and sell, from time to time at its sole discretion, shares of its common stock, par value $0.0001 per share (“Common Stock”), having an aggregate offering price of up to $2.0 billion (the “Shares”) through one or more of the Agents or directly to such Agents acting as principals for their own accounts at a price and on terms agreed upon in separate written agreements. The issuance and sale, if any, of the Shares by the Company under the Agreement will be made pursuant to a prospectus supplement, dated March 28, 2025, and a base prospectus, filed with the U.S. Securities and Exchange Commission (the “SEC”) on February 29, 2024, relating to the Company’s effective shelf registration statement on Form S-3ASR (File No. 333-277498) (the “Registration Statement”).

Upon the Company’s delivery of a placement notice and subject to the terms and conditions of the Agreement, the Agents may sell the Shares by any method permitted by law deemed to be an “at the market offering” as defined in Rule 415(a)(4) promulgated under the Securities Act of 1933, as amended, or by any another method. Each Agent, as applicable, will use commercially reasonable efforts consistent with its normal trading and sales practices and applicable state and federal law, rules and regulations and the rules of the Nasdaq Capital Market to sell the Shares from time to time, based upon instructions from the Company (including any price, time or size limits or other customary parameters or conditions the Company may impose). The Agents, as applicable, will be entitled to compensation at a commission rate of up to 3% of the gross proceeds from each sale of the Shares. The Company has provided the Agents with customary indemnification and contribution rights.

The Company is not obligated to make any sales, and the Agents are not obligated to buy and sell, any of the Shares under the Agreement. The Company or any Agent (solely with respect to such Agent) may suspend or terminate the offering of the Shares upon notice to the other party and subject to other conditions.

The foregoing description of the Agreement does not purport to be complete and is qualified in its entirety by reference to the full text of the Agreement, a copy of which is filed as Exhibit 1.1 to this Current Report on Form 8-K and is incorporated herein by reference. The legal opinion of Brownstein Hyatt Farber Schreck, LLP, relating to the validity of the Shares being offered pursuant to the Agreement, is filed as Exhibit 5.1 to this Current Report on Form 8-K and is incorporated herein by reference.

This Current Report on Form 8-K shall not constitute an offer to sell or the solicitation of an offer to buy any Shares under the Agreement nor shall there be any sale of such Shares in any state in which such offer, solicitation or sale would be unlawful prior to registration or qualification under the securities laws of any such state.

Item 1.02. Termination of a Material Definitive Agreement.

In connection with entering into the Agreement, effective as of March 28, 2025, the Company terminated that certain At The Market Offering Agreement, dated October 24, 2023, by and between the Company and H.C. Wainwright & Co., LLC (the “Prior ATM Agreement”), relating to the at-the-market offering of shares of Common Stock having an aggregate offering price of up to $1.5 billion. Accordingly, with the termination of the Prior ATM Agreement, the Company also terminated its “at-the-market” offering of shares of Common Stock conducted pursuant to the Company’s prospectus supplement filed with the SEC as part of the Registration Statement on February 29, 2024 (the “Prior Prospectus Supplement”). No further offerings or sales of common stock will be conducted under the Prior ATM Agreement or the Prior Prospectus Supplement.
