Atwood Oceanics, Inc. ("Atwood") is an offshore drilling contractor headquartered in Houston, Texas that focuses on deepwater and ultra-deepwater drilling.

According to the Complaint, on May 29, 2017, Atwood’s Board of Directors caused the Company to enter into an agreement and plan of merger (the “Merger Agreement”) with Ensco. Pursuant to the terms of the Merger Agreement, shareholders of Atwood will receive 1.60 Class A ordinary shares of Parent per Atwood share, valued at approximately $10.72 per share.

On June 16, 2017, Defendants filed a Form S-4 Registration Statement with the United States Securities and Exchange Commission in connection with the Proposed Transaction. The Complaint alleges the Registration Statement omits material information with respect to the Proposed Transaction, which renders the Registration Statement false and misleading.

On June 26, 2017, Plaintiff filed a corrected amended Complaint.

On October 2, 2017, the Court issued an Order Consolidating Cases. The Consolidated Cases shall be identified as: “In Re Atwood Oceanics, Inc. Shareholder Litigation.”

This case was voluntarily dismissed as moot on November 6, 2017.
