Federal regulators are investigating ExxonMobil's $60 billion deal to acquire a Texas oil company in what would be one the largest mergers in the energy industry in two decades, according to securities filings.
The Federal Trade Commission, which enforces federal antitrust law, has asked for additional information from the companies about Exxon’s proposed acquisition of Pioneer Natural Resources. The request is a step the agency takes when reviewing whether a merger could be anticompetitive under U.S. law. Pioneer disclosed the request in a filing Tuesday.
