United Rentals announced this week that the U.S. Federal Trade Commission has granted early termination of the waiting period under the Hart-Scott-Rodino Antitrust Improvements Act related to its acquisition of National Pump, the second largest specialty pump rental company in North America.

United Rentals announced the acquisition of Beaumont, Texas-based National Pump earlier in the week for $780 million in a deal that includes GulfCo., a two-location general rental company also based in Texas.

The closing of the transaction remains subject to other conditions set forth in the definitive asset purchase agreement. United Rentals expects the transaction to close early in the second quarter.

Based in Stamford, Conn., United Rentals is No. 1 on the RER 100.
