Nabors Announces Offerings Of Common Shares And Mandatory Convertible Preferred Shares

HAMILTON, Bermuda, May 9, 2018

Each mandatory convertible preferred share is expected to have a liquidation preference of $50 per share.

Unless earlier converted, each mandatory convertible preferred share will automatically convert into a variable number of Nabors' common shares on the mandatory conversion date, which is expected to be May 1, 2021. The number of Nabors' common shares issuable on mandatory conversion will be determined based on the average of the volume-weighted average prices of Nabors' common shares over the 20-trading day period commencing on and including the 21st scheduled trading day immediately preceding May 1, 2021. The dividend rate and the conversion terms of the mandatory convertible preferred shares will be determined at the time of pricing of the offering of the mandatory convertible preferred shares.
