Commercial consignment for ADESA was up 24 percent year-over-year in the second quarter, helping to lift the auction company’s vehicle sales by double-digits, parent company KAR Auction Services said Wednesday.

The number of vehicles sold via ADESA climbed by 18 percent year-over-year in Q2. Excluding numbers from acquired locations, sales were up 9 percent, with commercial consignment climbing 17 percent.

“The cyclical recovery at ADESA continues. We’re seeing increasing volumes of off-lease cars, and they’re expected for the remainder of this year and then for the next few years,” KAR Auction Services chief executive Jim Hallett said Wednesday during the company’s quarterly earnings call.

“In fact, leasing continues to increase as a percent of new-car sales. And as we’ve said before, the increases in commercial volumes, especially the off-lease and the repo vehicles, may cause dealer consignment volumes to decline in the future,” he said.

In Q2, dealer consignment was up 9 percent when acquisitions were included, but down 3 percent when they were not.

During the Q&A portion of the call, Hallett also touched on the rental-car segment of ADESA’s business, an area in which volume is expected to pick up heading into the third quarter.

“It’s the smallest portion of our commercial business, but we continue to receive rental vehicles. And as we start to approach Labor Day and the Labor Day weekend, that’s usually a time that these rental companies start to de-fleet,” Hallett said. “It’s just a seasonal thing; kids are back at school, holidays are over. There’s less demand and the de-fleeting starts.”

Year-to-date, ADESA’s sales volume was up 18 percent (up 13 percent when excluding acquisitions). Commercial consignment climbed 23 percent in the first six months of the year (up 19 percent excluding acquisitions). Dealer consignment volume was up 9 percent (up 2 percent excluding acquisitions).
