Time utilization increased 190 basis points year over year to 69.4 percent, a second quarter record, with each month in the quarter establishing a new monthly record. On a pro forma basis, time utilization increased 210 basis points year over year.

United Rentals’ Trench, Power and Pump specialty segment’s rental revenue jumped 18.5 percent year over year, primarily on a same-store basis, while the segment’s rental gross margin improved by 250 basis points to 49.6 percent.

“The broad demand we saw early this year continued throughout the second quarter as we entered our busy season,” said Michael Kneeland, CEO of United Rentals. “This was reflected in our strong year-over-year performance, with volume up 6.6 percent on a pro forma basis, record second quarter time utilization and an improved rate trend across our business. The NES integration and Project XL are both well underway and on track.

“We remain encouraged by the level of customer activity and the industry’s ongoing absorption of fleet. Given our visibility into the balance of 2017, we’ve increased our full-year guidance for total revenue, adjusted EBITDA, capex and free cash flow. Our focus remains on balancing growth with margins, free cash flow and returns to maximize our long-term value.”

For the first six months of 2017, rental revenue increased 9.1 percent year over year. Owned equipment rental revenue increased 8.8 percent year over year, reflecting a 12.4-percent jump in the volume of equipment on rent, partially offset by a 1.2-percent decrease in rental rates.
