M&A practitioners have long regarded the integration planning and execution process as one of the keys to a successful M&A transaction. However, in deals subject to pre-merger antitrust clearance, it is critical to navigate the line between deal provisions and arrangements intended to preserve the value of the target business and allow the parties to prepare for post-closing integration, versus those that could result in the buyer exerting control over the target business or accessing competitively sensitive information prior to closing in a manner that could be seen as potentially harming competition in violation of the US antitrust laws. This conduct, commonly referred to as “gun-jumping,” can result in investigations by the Federal Trade Commission (FTC) and the Justice Department’s Antitrust Division (DOJ) as well as significant civil penalties for violation of the pre-merger notification and waiting period requirements of the Hart-Scott-Rodino Antitrust Improvements Act of 1976 (the “HSR Act”).
A noteworthy complaint filed by the DOJ on January 7, 2025, at the request of the FTC, serves as a reminder of the risks to merging parties of not properly navigating these considerations during the pre-closing period. DOJ’s complaint alleges that the Defendants, merging crude oil producers XCL Resources Holdings, LLC (“XCL”), Verdun Oil Company II LLC (“Verdun”), and EP Energy LLC (“EP”), engaged in gun jumping in violation of the HSR Act by allowing Verdun and XCL to immediately assume control over certain of EP’s day-to-day business operations and by exchanging non-public, competitively sensitive information (CSI) before the HSR Act’s waiting period had elapsed. The proposed settlement provides for a $5.6 million civil penalty, which the FTC heralded as “the largest dollar penalty imposed for a gun-jumping violation in U.S. history.”[1]
