According to the Complaint, Carrizo Oil & Gas, Inc. is an energy company actively engaged in the exploration, development, and production of oil and gas from resource plays located in the United States.

This action stems from a proposed transaction announced on July 15, 2019, pursuant to which Carrizo will be acquired by Callon Petroleum Company.

On July 14, 2019, Carrizo’s Board of Directors caused the Company to enter into an agreement and plan of merger with Callon. Pursuant to the terms of the Merger Agreement, Carrizo’s stockholders will receive 2.05 shares of Callon stock for each share of Carrizo common stock they own.

On August 20, 2019, 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 that the Registration Statement omits material information with respect to the Proposed
Transaction, which renders the Registration Statement false and misleading.

This case was voluntarily dismissed on February 12, 2020.
