French IT services company Atos SE said the Committee on Foreign Investment in the United States approved its pending $3.57 billion all-cash acquisition of U.S. data processing and digital services company Syntel Inc.

The approval is the final regulatory clearance needed for the deal, Atos said, after previous clearances from antitrust authorities in the U.S., Austria, Serbia and India.

Syntel announced July 22 that Atos agreed to pay $41 per share for all of its outstanding stock.

The target's shareholders are scheduled to vote on the deal at a special meeting Oct. 1. The deal is expected to close in the fourth quarter, Atos said.
