Best Buy had a good holiday season

Consumer electronics retailer Best Buy reported strong fourth-quarter sales and profit, and shares soared 14.1%. Revenue fell 3.7% to $14.8 billion, but last year's Q4 revenue was boosted by $760 million due to an extra week. Excluding that, revenue grew 1.4% year over year. Adjusted earnings per share jumped 12.4% to $2.72. The revenue was at the top end of guidance and EPS was 7.5% above the midpoint of the company's conservative forecast three months ago.

Comparable-store sales increased 3%, compared with guidance of flat to up 3%. Best Buy said that comparable-store sales gains were driven by strength in wearables, appliances, smart home, and gaming. 

Looking forward, Best Buy expects full-year comparable-store sales growth between 0.5% and 2.5%, and non-GAAP EPS to increase between 2.4% and 6.2%, better than the 3.2% analysts have been expecting. The company also boosted its quarterly dividend by 11% to $0.50, resulting in a forward yield of 2.9%. Last year Best Buy used $1.5 billion for share buybacks, which reduced the share count by 7.9%, and expects to spend between $750 and $1 billion for that purpose this year.
