Pick a financial statement metric — net sales and operating revenues, net earnings, used unit sales, finance arm income — and CarMax posted a double-digit jump year-over-year during the third quarter of its current fiscal year.

The company said Thursday that its third-quarter net earnings grew 15 percent to $94.7 million or $0.41 per diluted share, compared with $82.1 million or $0.36 per diluted share, in the third quarter of previous fiscal year.

CarMax highlighted that its used-vehicle sales volume improved significantly with total used units climbing 16 percent and comparable store used units up 12 percent.

“The comparable store used unit growth was driven by improved conversion, which we believe benefited from a variety of factors; including more compelling credit offers from third-party finance providers and CarMax Auto Finance, increased inventory selection, improved customer sentiment and continued strong in-store execution,” officials said.

The company added that the used-vehicle average selling price was similar to the prior year’s quarter.

Meanwhile, CarMax enjoyed wholesale vehicle unit sales improvement, too, as volume grew 10 percent compared with last year’s quarter. Officials indicated wholesale unit sales benefited from an increase in appraisal traffic, while the appraisal buy rate was similar to the prior year’s quarter.

The company mentioned other sales and revenues increased 5 percent compared with the prior year’s third quarter as an increase in extended service plan (ESP) revenues was largely offset by a reduction in net third-party finance fees.

CarMax noted third-party subprime providers, who purchase subprime financings at a discount, originated 14 percent of used-vehicle unit sales in the recent quarter compared with 9 percent in the prior year quarter. ESP revenues climbed 22 percent due to both the growth in used-vehicle sales and an increase in ESP penetration.

All told, the company calculated total gross profit increased 14 percent to $345.2 million from $303.2 million in the third quarter of the previous fiscal year, primarily reflecting the increased used and wholesale vehicle unit sales as well as higher other gross profit.

Looking specifically at CarMax Auto Finance, the division’s income increased 16 percent to $72.5 million compared with $62.6 million in last year’s third quarter.

The growth in CAF income was largely attributable to the 15-percent increase in average managed receivables, which grew to $5.48 billion from $4.77 billion in the prior-year period.

“The increase in average managed receivables reflected the rise in CAF origination volume throughout fiscal 2012 and fiscal 2013 as we transitioned back to our pre-recession origination strategy, higher average amounts financed and the growth in retail unit sales,” officials said.

After reviewing the company’s entire quarterly performance, president and chief executive officer Tom Folliard said, “We are pleased to report strong increases in used and wholesale vehicle unit sales and CAF income, which drove solid bottom-line earnings growth. Our strong comparable store sales growth allowed us to leverage SG&A expenses, even as we expanded our store base.”
