Ford Motor misses on top and bottom line

Ford Motor (F) delivered quarterly earnings and revenue that fell short of analysts' expectations on Tuesday, as it sold fewer vehicles in North America due to the rollout of the F-150 pickup truck and continued to lose money in South America and Europe.

The No. 2 U.S. automaker maintained its full-year forecast of pre-tax profit of between $8.5 billion and $9.5 billion.

The company raised its forecast for North American operating margin to 8.5 percent to 9.5 percent from 8 percent to 9 percent, but highlighted worsening business conditions in South America.

"The external environment in South America has deteriorated compared to where we were just a few months ago," Ford Chief Financial Officer Bob Shanks said to reporters.

The nation's second-largest automaker posted first-quarter earnings of 23 cents per share, down from 25 cents a share in the year-earlier period.

Revenue fell to $31.8 billion from $33.9 billion a year ago.

Wall Street had expected the company to deliver quarterly earnings per share of 26 cents on $33.9 billion in revenue, according to consensus estimates from Thomson Reuters.
