CHICAGO — U.S. comparable sales increased 5.7% for McDonald’s Corp. in the second quarter ended June 30.

The company, when reporting financial results on July 26, attributed the increase to national and local deal offers, including the 2 for $5 Mix and Match deal; a positive impact from the chain’s “Experience of the Future” deployment and strength in core menu items.

Global comparable sales increased 6.5%. Companywide second-quarter net income of $1,516.9 million, or $1.97 per diluted share, was up 1.4% from $1,496.3 million, or $1.90, in the previous year’s second quarter. Second-quarter revenues of $5,341.3 million were down 0.2% from $5,353.9 million. The strong comparable sales were offset partly by the impact of refranchising.

“By engaging our guests on their terms, whether it’s through delivery, an enhanced dining experience at one of our ‘Experience of the Future’ restaurants or through our evolving digital offerings, we’re becoming a better McDonald’s,” said Steve Easterbrook, president and chief executive officer.
