Sable Offshore Corp. (New York Stock Exchange: SOC) today announced the pricing of its concurrent public offerings of 32,467,533 shares of common stock, at a public offering price of $3.08 per share, and $300.0 million aggregate principal amount of 6.5% convertible senior notes due 2031 (the "notes"). The issuance and sale of the common stock and the notes are scheduled to settle on July 2, 2026, subject to customary closing conditions. Sable also granted the underwriters of the common stock offering a 30-day option to purchase up to an additional 4,870,129 shares of common stock solely to cover over-allotments, and granted the underwriters of the notes offering a 30-day option to purchase up to an additional $45.0 million aggregate principal amount of notes solely to cover over-allotments.

J.P. Morgan is acting as sole book-running manager for the common stock offering and the notes offering.

The notes will be senior, unsecured obligations of Sable and will accrue interest at a rate of 6.5% per annum, payable semi-annually in arrears on January 1 and July 1 of each year, beginning on January 1, 2027. The notes will mature on July 1, 2031, unless earlier repurchased, redeemed or converted. Before April 1, 2031, noteholders will have the right to convert their notes only upon the occurrence of certain events. From and after April 1, 2031, noteholders may convert their notes at any time at their election until the close of business on the second scheduled trading day immediately before the maturity date. Sable will settle conversions by paying or delivering, as applicable, cash, shares of its common stock or a combination of cash and shares of its common stock, at Sable’s election. The initial conversion rate is 249.7502 shares of common stock per $1,000 principal amount of notes, which represents an initial conversion price of approximately $4.00 per share of common stock. The initial conversion price represents a premium of approximately 30% over the public offering price per share of common stock in the common stock offering. The conversion rate and conversion price will be subject to adjustment upon the occurrence of certain events.

The notes will be redeemable, in whole or in part (subject to certain limitations), for cash at Sable’s option at any time, and from time to time, on or after July 6, 2029 and on or before the 40th scheduled trading day immediately before the maturity date, but only if the last reported sale price per share of Sable’s common stock exceeds 175% of the conversion price for a specified period of time. The redemption price will be equal to the principal amount of the notes to be redeemed, plus accrued and unpaid interest, if any, to, but excluding, the redemption date.

If a "fundamental change" (as defined in the indenture for the notes) occurs, then, subject to a limited exception, noteholders may require Sable to repurchase their notes for cash. The repurchase price will be equal to the principal amount of the notes to be repurchased, plus accrued and unpaid interest, if any, to, but excluding, the applicable repurchase date. In addition, noteholders may require Sable to repurchase their notes on July 6, 2029, at a cash repurchase price equal to the principal amount of the notes to be repurchased, plus accrued and unpaid interest, if any, to, but excluding, the repurchase date.

Sable estimates that the net proceeds from the common stock offering will be approximately $92.8 million (or approximately $107.0 million if the underwriters of the common stock offering fully exercise their option to purchase additional shares of common stock), after deducting the underwriting discounts and commissions and estimated offering expenses. Sable estimates that the net proceeds from the notes offering will be approximately $288.8 million (or approximately $332.5 million if the underwriters of the notes offering fully exercise their option to purchase additional notes), after deducting the underwriting discounts and commissions and Sable’s estimated offering expenses. Sable intends to use the net proceeds from the common stock offering and the notes offering, together with the proceeds from the previously announced New Senior Secured Term Loan, to repay its Senior Secured Term Loan with Exxon Mobil Corporation, to pay transaction fees and expenses and for general corporate purposes. The New Senior Secured Term Loan, the common stock offering and the notes offering are cross conditioned, and accordingly each transaction will be consummated only if all such transactions are consummated.

The offerings are being made pursuant to an effective shelf registration statement on file with the Securities and Exchange Commission (the "SEC"). Each offering will be made only by means of a prospectus supplement relating to that offering (including any supplements thereto) and an accompanying prospectus. An electronic copy of the preliminary prospectus supplement (and, when available, the final prospectus supplement) for each offering, together with the accompanying prospectus, is or will be available on the SEC’s website at www.sec.gov. Alternatively, copies of these documents can be obtained by contacting: J.P. Morgan Securities LLC, c/o Broadridge Financial Solutions, 1155 Long Island Avenue, Edgewood, New York 11717, by email at prospectus-eq_fi@jpmchase.com and postsalemanualrequests@broadridge.com.
