CarMax posted double-digit increases in both net earnings and used vehicles retailed during the second quarter of its fiscal year.

And the company highlighted on Friday that CarMax achieved those results even though six stores in Houston were closed for a week because of Hurricane Harvey, creating a “modest adverse effect” on comparable store used-unit sales.

All told, CarMax retailed 186,019 units during the quarter that closed on Aug. 31, representing an 11.1-percent lift year-over-year. Halfway through its current fiscal year, CarMax stores have turned 381,292 units, producing a 12.6-percent improvement.

On a comparable store basis, the CarMax retail improvement wasn’t quite as robust, but still the company posted a healthy 5.3-percent year-over-year gain.

“The comparable store sales performance reflected continued solid improvement in conversion resulting from strong execution by our store teams and our digital initiatives,” the company said in a news release that accompanied its financial statement.

The metal rolling over the curb help CarMax generate a 9.7 percent rise net sales and operating revenues to $4.39 billion. As a result, net earnings increased 11.7 percent to $181.4 million and net earnings per diluted share rose 16.7 percent to $0.98.

The company calculated that its total gross profit increased 10.8 percent versus last year’s second quarter, climbing to $604.0 million. CarMax also highlighted its used-vehicle gross profit rose 12.0 percent, driven by the 11.1-percent increase in total used unit sales.

Used-vehicle gross profit per unit was consistent at $2,178 versus $2,160 in the prior year period.

On the wholesale front, CarMax sold 105,508 units through its auction channel during the second quarter, and halfway through the fiscal year the figure sits at 208,951 units. Both readings are nearly flat on a year-over-year comparison

Executives added wholesale vehicle gross profit increased 9.6 percent versus the prior year’s quarter, primarily due to an increase in wholesale vehicle gross profit per unit to $950 from $870.

“We believe this year’s second quarter wholesale gross profit per unit benefited from a favorable depreciation environment, relative to historical trends,” CarMax executive said. “Other gross profit increased 6.9 percent, primarily reflecting the changes in other sales and revenues.”

Also of note from the company’s latest financial performance, the company said CarMax Auto Finance (CAF) income increased 12.5 percent to $107.9 million. Average managed receivables grew 10.6 percent to $11.11 billion.

CAF indicated the total interest margin — which reflects the spread between interest and fees charged to consumers and the company’s funding costs, was 5.8 percent of average managed receivables compared with 5.9 percent in last year’s second quarter.

The provision for loan losses declined 7.8 percent to $32.9 million, compared with $35.7 million in the prior year quarter. The prior year’s provision was affected by unfavorable loss experience, while in the current year’s quarter, losses were generally consistent with expectations.

CAF went on to mention the allowance for contract losses as a percentage of ending managed receivables was 1.15 percent as of Aug. 31, compared with 1.18 percent reported as of May 31, and up from the 1.08 percnet reported as of Aug. 31,  of las year, “reflecting higher loss experience over the course of the last year,” according to the company.
