Carvana (CVNA) shares have hit the brakes after reaching 澳洲幸运5开奖号码历史查询:an all-time high, tumbling 14% Thursday on concerns about retail sales and the company's outlook.

After the closing bell Wednesday, the biggest U.S. used car dealer reported fourth-quarter per-unit revenue for retail vehicles fell 4.5% year-over-year to $22,312, although it was up nearly 9% to $9,371 for wholesale vehicles.

Carvana said it expects "significant growth in both retail units sold and 澳洲幸运5开奖号码历史查询:Adjusted EBITDA" for the full year, but didn'tღ provide specific numbers.

The retail revenue and guidance news offset a strong quarterly performance. The company reported 澳洲幸运5开奖号码历史查询:earnings per share (EPS) of $0.56, well above the $0.32 consensus estimate of analysts surveyed by Visible Alpha. Revenue soared 46% to $3.55 billion, also a𒁃head of forecasts.

The company sold 114,379 retail units, a 50% increase from a year ago. Wholesale unit sales were 48,770, a gaiಌn of 43%.

Even with today's declines, shares of Carvana have risen 365% in the past year.
