Better still, Dick's is becoming more profitable as it expands its revenue base. The retailer's gross and operating margins improved to 39.9% and 20.3%, respectively, up from 34.5% and 14.4% in the year-ago period.. Dick's adjusted net income, in turn, soared 78% to $501.2 million, or $5.08 per share.

"Our record-breaking quarterly sales and earnings significantly exceeded our expectations, reflecting continued strong consumer demand across our diverse category portfolio," CEO Lauren Hobart said in a press release.

Now what

With its profits swelling, Dick's is ramping up its capital returns to investors. It boosted its quarterly dividend by 21% to $0.4375 per share and doubled its stock buyback program to a minimum of $400 million. Dick's also announced a $5.50 per share special dividend payable on Sep. 24 to stockholders of record on Sep. 10.

"This additional cash return to our shareholders demonstrates the confidence we have in our business, the strength of our balance sheet, and a commitment to efficiently deploy our cash," Hobart said.

Looking ahead, management sees Dick's full-year net sales and adjusted earnings per share growing by roughly 21% and 108%, respectively, in 2021.
