Iconic burger chain Wendy's  (WEN - Get Report) served up better-than-expected second-quarter earnings but came up shy on the top line.

Adjusted earnings in the quarter were 18 cents a share, up from 14 cents in the same period a year earlier.  Analysts had been expecting 17 cents. 

Revenue was lighter than expected at $435 million, up from $411 million a year ago but shy of the $440 million in revenue that Wall Street analysts expected. Same-store sales in North America rose 1.4%, above forecasts of 1.3%.

Profit margins at company-operated restaurants also got squeezed to 16.5% in the three-month period, down from 17.4% in 2018.

That dip was "primarily the result of labor rate inflation, customer count declines, and higher commodity costs, partially offset by pricing actions," the company said in a press release.

Still, the CEO seems focused on improving the company's performance. 

"We are executing on our plan to accelerate same-restaurant sales in North America and drive global restaurant expansion, fueled by a healthy restaurant economic model," CEO Todd Penegor in a statement.

Wendy's said it expects systemwide sales growth of 3% to 4% in 2019.
