Freeport-McMoRan Announces

Upsizing and Pricing of $1.3 Billion of Senior Notes

PHOENIX, AZ, February 19, 2020 — Freeport-McMoRan Inc. (NYSE: FCX) announced today that it has priced an upsized offering of $1.3 billion of senior notes (collectively, the Notes). The offering size was increased to $1.3 billion from the previously announced $1.0 billion aggregate principal amount. Following is a summary of the two tranches of debt:

The sale of the senior notes is expected to settle on March 4, 2020, subject to customary closing conditions. Concurrently with this offering, FCX is conducting cash tender offers for up to $1.1 billion aggregate purchase price, subject to increase or decrease and exclusive of accrued interest, of its 4.00% Senior Notes due 2021 (the 2021 notes), 3.55% Senior Notes due 2022, 3.875% Senior Notes due 2023 and 4.55% Senior Notes due 2024 (collectively, the Tender Offers). FCX intends to use the net proceeds from the offering to fund the Tender Offers and the payment of accrued and unpaid interest, premiums, fees and expenses in connection therewith. To the extent all of the 2021 notes are not tendered and purchased in the Tender Offers, FCX may, but is not obligated to, use a portion of any remaining net proceeds from the offering to redeem all or a portion of the remaining 2021 notes in accordance with the provisions of the indenture governing the 2021 notes. These transactions will enable FCX to extend the maturities of certain of its outstanding indebtedness.
