“2016 was a year of transition, and as we move into 2017 our focus will be on driving industry leading returns,” Lesar said in a statement. “We will continue to maintain our financial flexibility, leverage our strong balance sheet to invest in our broad service portfolio and strengthen our long term market position.”
