"We capped a year of record results with a strong fourth quarter finish on the back of broad-based demand,” said Michael Kneeland, United Rentals CEO. “Pro forma volume increased nearly 9 percent year over year in the quarter, and rental rates were up 2 percent. For the full year, we exceeded the upper-band of guidance on total revenue, adjusted EBITDA and free cash flow, and increased our ROIC by 50 basis points year over year to its highest level since 2015.

"Our 2018 guidance reflects the confidence we feel in our operating environment based on what we hear from customers and see in key leading indicators. Our optimism is further supported by the tailwinds we expect from leveraging our 2017 acquisitions and our ongoing investments in people and technology, as well as the recent U.S. tax reform. Our strategy remains focused on balancing growth and returns to maximize our long-term value."
