ST. LOUIS, May 26, 2022 /PRNewswire/ — Wholly‐owned subsidiaries of Peabody (NYSE: BTU), PIC AU Holdings LLC, a Delaware limited liability company (the "Main Issuer"), and PIC AU Holdings Corporation, a Delaware corporation (together with the Main Issuer, the "Co‐Issuers"), today announced that the Co-Issuers successfully completed the repurchase of $50.0 million aggregate principal amount of the Co-Issuers’ 10.000% senior secured term loan due 2024 at a weighted average purchase price of 103.91% of par, in accordance with the Credit Agreement, dated January 29, 2021, among the Co-Issuers, as co-borrowers, the lenders party thereto from time to time and Wilmington Trust, National Association (as successor to JPMorgan Chase Bank, N.A.), as administrative agent, which governs the term loans.

The Co-Issuers also announced today an offer to purchase (the "Offer") for cash up to $50.0 million aggregate principal amount (the " Offer Amount") of their 10.000% Senior Secured Notes due 2024 (the "Notes"), at a purchase price equal to 103.91% of the principal amount of the Notes repurchased in the Offer, plus accrued and unpaid interest, if any, to, but excluding, the settlement date for the Offer, on the terms and subject to the conditions set forth in the Co-Issuer’s Offer to Purchase, dated May 26, 2022 (the "Offer to Purchase"). The Notes are governed by an indenture, dated January 29, 2021, by and among the Co-Issuers, Wilmington Trust, National Association, as trustee, and Peabody (on a limited basis, to the extent of its obligations specifically set forth in the Indenture) (as amended and restated by the First Supplemental Indenture dated February 3, 2021, and as further amended, supplemented, restated or otherwise modified to the date hereof, the "Indenture").

Under the terms of the Indenture, no later than 30 business days following any voluntary prepayment, repayment or repurchase of term loans, the Co-Issuers are required to make an offer to purchase an aggregate principal amount of Notes equal to the aggregate principal amount of term loans so prepaid, repaid or repurchased. The Offer is intended to satisfy this requirement.

The Offer will expire at 5:00 p.m., New York City time, on June 27, 2022, unless extended or earlier terminated by the Co-Issuers in accordance with the terms of the Offer and the Indenture (the "Expiration Time"). Subject to the Offer Amount, for each $1,000 principal amount of Notes validly tendered (and not validly withdrawn) prior to the Expiration Time and accepted by the Co-Issuers for purchase in the Offer, holders of Notes will receive the Offer Price of $1,039.10 in cash, plus accrued and unpaid interest as set forth in the Indenture, to, but excluding, the settlement date for the Offer. Tendered Notes may be validly withdrawn at any time prior to the Expiration Time, unless extended or earlier terminated by the Co-Issuers. The settlement date for the Offer is currently expected to be the second business day following the Expiration Time.
