(Bloomberg) -- Albertsons Cos. shares climbed after the company posted a surprise gain in a key sales metric and raised its profit outlook. 

Same-store sales rose 1.5% during the second fiscal quarter, the supermarket chain said Monday as it reported earnings, bucking Wall Street’s expectations of a 1.9% decline. Adjusted earnings for the fiscal year will be as much as $2.60 a share, up 30 cents from the previous forecast. 

Albertsons is benefiting from buoyant consumer spending as customers continue to channel much of their food budget to home-cooked meals, Chief Executive Officer Vivek Sankaran said in an interview. The company is also coaxing shoppers to spend a little more at its stores compared with those of its rivals, he said. 

“Consumers are still eating a lot more at home, we see those patterns seem to be sticking,” he said. “The second part of it is market-share growth. One metric I feel excited about is our market-share gains.” 

Albertsons advanced 5.4% to $30.10 ahead of regular trading in New York. The shares climbed 62% this year through Oct. 15, six times the gain of an S&P index composed of five other sellers of food and staples. 

At Albertsons, adjusted earnings rose to 64 cents a share in the quarter ending Sept. 11, compared with the 46-cent average of analyst estimates compiled by Bloomberg. Sales increased 4.7% to $16.5 billion. Analysts had predicted $15.9 billion. 

The Boise, Idaho-based retailer raised its quarterly dividend to 12 cents a share from 10 cents.
