26 |  | Acquisition of subsidiaries
In September 2017, Tenaris acquired 100% of Garrett (a pipe services and trucking business) through the payment of a price of $10.4 million. If the acquisition had occurred on January 1, 2017, Tenaris’s unaudited pro forma net sales and net income from continuing operations would not have changed materially.
