Weatherford Prices Upsized Public Offering of $1.5 Billion of Senior Notes

Baar, Switzerland, June 10, 2016 – Weatherford International plc (NYSE: WFT) (the “Company” or “Weatherford”) announced today the pricing of an upsized underwritten public offering (the “Offering”) of $1.5 billion aggregate principal amount of senior notes, consisting of $750,000,000 aggregate principal amount of 7.750% senior notes due 2021 (the “2021 Notes”) and $750,000,000 aggregate principal amount of 8.250% senior notes due 2023 (the “2023 Notes” and, together with the 2021 Notes, the “Notes”). The Notes will be senior, unsecured obligations of Weatherford International Ltd., a Bermuda exempted company and indirect, wholly owned subsidiary of the Company (“Weatherford Bermuda”). The Offering is expected to close June 17, 2016, subject to customary closing conditions.

The Company intends to use the net proceeds from the Offering to fund an increase to the maximum aggregate purchase price for its recently announced tender offers from $1.1 billion to $2.6 billion. The tender offers were made to purchase for cash certain of its 6.35% senior notes due 2017, 6.00% senior notes due 2018, 9.625% senior notes due 2019 and 5.125% senior notes due 2020 (the “Tender Offers”). In the event the Tender Offers, which are subject to market conditions and other factors, are not consummated, or the aggregate amount of securities tendered in the Tender Offers and accepted for payment is less than the net proceeds of the Offering, we may use such proceeds to repay or retire other outstanding indebtedness, which may include amounts under Weatherford Bermuda’s revolving credit facility.

Morgan, Morgan Stanley and MUFG are acting as joint book-running managers for the Offering.
