McDonald's Corp reported second-quarter earnings on Friday that slightly topped Wall Street estimates, helped by same-store sales gains across all regions.

Second-quarter net income at the world's biggest hamburger chain was $1.23 billion, or $1.13 per share, up from $1.09 billion, or 98 cents per share, a year earlier.

Analysts on average called for a profit of $1.12 per share, according to Thomson Reuters I/B/E/S.

Revenue, which includes sales from company-owned restaurants plus royalties from franchisees and other fees, rose 5 percent to $5.95 billion.

McDonald's shares were down $1.41, or 2 percent, at $69.99 in premarket trading.
