This Amendment No. 1 ("Amendment No. 1") amends and supplements the statement on Schedule 13D filed with the Securities and Exchange Commission (the "SEC") on July 21, 2014 (the "Original Schedule 13D" and together with this Amendment No. 1, the "Schedule 13D") with respect to the Class A ordinary shares, $0.125 par value (the "Class A Ordinary Shares"), of Rowan Companies plc, a public limited company organized under the laws of England and Wales (the "Issuer"). Capitalized terms used herein and not otherwise defined in this Amendment No. 1 have the meanings set forth in the Schedule 13D. This Amendment No. 1 amends Items 3 and 5 as set forth below.

 

Item 3. SOURCE AND AMOUNT OF FUNDS OR OTHER CONSIDERATION
   
Item 3 of the Schedule 13D is hereby amended and restated in its entirety as follows:
   
 

The Reporting Persons used $305,033,381 (excluding brokerage commissions) in the aggregate to purchase the Class A Ordinary Shares reported in this Schedule 13D.

 

The source of the funds used to acquire the Class A Ordinary Shares reported herein is the working capital of the Manager, which at any given time may include funds borrowed on margin in the ordinary course and on customary terms.

 

Item 5. INTEREST IN SECURITIES OF THE ISSUER
   
Paragraphs (a) – (c) of Item 5 of the Schedule 13D are hereby amended and restated in their entirety as follows:

As of the date hereof, the Reporting Persons beneficially own an aggregate of 9,783,812 Class A Ordinary Shares, which Class A Ordinary Shares may be deemed to be beneficially owned by each of the Manager, Manager GP and Mr. Robbins, and which represent approximately 7.9% of the outstanding Class A Ordinary Shares.
