What happened Shares of home-furnishings lessor Aaron's Inc. (NYSE: AAN) fell as much as 10% in early trading Friday, after the company reported third-quarter 2017 earnings that fell short of Wall Street estimates.

After retracing its early losses somewhat, Aaron's stock closed the day down 7.4%. Rent? Own? At Aaron's you can do both. Image source: Getty Images. So what Aaron's earns revenue in the form of leasing fees, retail and other sales, franchise fees, and interest on loans. Combined, the company's revenues grew 9.1% from Q3 2016 levels to Q3 2017, rising to $838.9 million. Costs, however, grew even faster -- up 10.1% year over year. As a result, Aaron's net income declined in comparison to the year-ago period, falling 12.5% to $0.35 per share. Management blamed hurricanes Harvey and Irma for "disrupting" its business in the third quarter. Now what Despite the disruption, Aaron's reiterated its earnings guidance for the full year, as previously disclosed in its Q2 2017 report. Thus, Aaron's continues to expect revenue of between $3.33 billion and $3.44 billion this year. Earnings per share should range between $2.10 and $2.30, diluted. Taken at the midpoint, that works out to a closing share price of $39.14, divided by $2.20 in profit, making Aaron's P/E ratio 17.8. That's kind of expensive for a rental business expected to grow at only 12%, and coming off a quarter in which it grew not at all.
