Fort Lauderdale, FL, August 14, 2024 (GLOBE NEWSWIRE) — Marathon Digital Holdings, Inc. (NASDAQ: MARA) (“MARA” or the “Company”), a global leader in leveraging digital asset compute to support the energy transformation, today announced the closing of its offering of 2.125% convertible senior notes due 2031 (the “notes”). The aggregate principal amount of the notes sold in the offering was $300 million, which includes $50 million aggregate principal amount of notes issued pursuant to an option to purchase, within a 13-day period beginning on, and including, the date on which the notes were first issued, granted to the initial purchasers under the purchase agreement, which the initial purchasers exercised in full on August 13, 2024 and which additional purchase was completed on August 14, 2024. The notes were sold in a private offering to persons reasonably believed to be qualified institutional buyers in reliance on Rule 144A under the Securities Act of 1933, as amended (the “Securities Act”).

The net proceeds from the sale of the notes were approximately $292.5 million, after deducting the initial purchasers’ discounts and commissions but before estimated offering expenses payable by MARA. On August 14, 2024, MARA also announced that, during the period between August 12, 2024 and August 14, 2024, MARA acquired approximately 4,144 bitcoin for approximately $249 million in cash, using proceeds from the sale of the notes, at an average price of approximately $59,500 per bitcoin, inclusive of fees and expenses. MARA intends to use the remaining net proceeds from the sale of the notes to acquire additional bitcoin and for general corporate purposes, which may include working capital, strategic acquisitions, expansion of existing assets, and repayment of debt and other outstanding obligations.

The notes are unsecured, senior obligations of MARA and bear interest at a rate of 2.125% per annum, payable semi-annually in arrears on March 1 and September 1 of each year, beginning on March 1, 2025. The notes will mature on September 1, 2031, unless earlier repurchased, redeemed or converted in accordance with their terms. Subject to certain conditions, on or after September 6, 2028, MARA may redeem for cash all or any portion of the notes at a redemption price equal to 100% of the principal amount of the notes to be redeemed, plus accrued and unpaid interest, if any, to, but excluding, the redemption date, if the last reported sale price of MARA’s common stock has been at least 130% of the conversion price then in effect for a specified period of time ending on, and including, the trading day immediately before the date MARA provides the notice of redemption. If MARA redeems fewer than all the outstanding notes, at least $75 million aggregate principal amount of notes must be outstanding and not subject to redemption as of the relevant redemption notice date.

Holders of notes may require MARA to repurchase for cash all or any portion of their notes on March 1, 2029 or upon the occurrence of certain events that constitute a fundamental change under the indenture governing the notes at a repurchase price equal to 100% of the principal amount of the notes to be repurchased, plus any accrued and unpaid interest to, but excluding, the date of repurchase. In connection with certain corporate events or if MARA calls any note for redemption, it will, under certain circumstances, be required to increase the conversion rate for holders who elect to convert their notes in connection with such corporate event or notice of redemption.

The notes are convertible into cash, shares of MARA’s common stock, or a combination of cash and shares of MARA’s common stock, at MARA’s election. Prior to March 1, 2031, the notes are convertible only upon the occurrence of certain events and during certain periods, and thereafter, at any time until the close of business on the second scheduled trading day immediately preceding the maturity date.

The conversion rate for the notes is initially 52.9451 shares of MARA’s common stock per $1,000 principal amount of notes, which is equivalent to an initial conversion price of approximately $18.89 per share. The conversion rate is subject to adjustment upon the occurrence of certain events.

The notes were sold to persons reasonably believed to be qualified institutional buyers pursuant to Rule 144A under the Securities Act. The offer and sale of the notes and the shares of MARA’s common stock issuable upon conversion of the notes, if any, have not been and will not be registered under the Securities Act or the securities laws of any other jurisdiction, and the notes and any such shares may not be offered or sold in the United States absent registration or an applicable exemption from such registration requirements. The offering of the notes was made only by means of a private offering memorandum.

This press release shall not constitute an offer to sell, or a solicitation of an offer to buy, the notes, nor shall there be any sale of the notes in any state or jurisdiction in which such offer, solicitation or sale would be unlawful under the securities laws of any such state or jurisdiction.
