Academy Sports and Outdoors reported higher profit and sales in its fiscal second quarter, giving the company confidence to raise its earnings outlook for the year.

The sporting-goods retailer on Wednesday posted a profit of $137.9 million, or $2.17 a share, for its quarter ended Aug. 1, compared with $125.4 million, or $1.85 a share, in last year's comparable period.

Stripping out one-time items, earnings came in at $2.31 a share. Analysts polled by FactSet expected adjusted earnings of $2.07 a share.

Sales climbed 3% to $1.65 billion, in line with Wall Street models. Comparable sales, which account for store openings and closings, fell 0.4%, compared with analyst views for a 0.2% decline.

"While consumer spending remains pressured, particularly among lower-income households, our team has continued to execute at a high level by focusing on the key events and categories that matter most to our customers," Chief Executive Steve Lawrence said.

Academy Sports is also re-investing tariff refunds back into the business, a move Lawrence said is helping the company to gain market share and strengthen its relationships with customers.
