Revenue fell 1 percent in its industrial segments, hurt by a $950 million (£632.4 million) hit from the stronger dollar, GE said on Friday. Stripping out the currency drag and the impact from deals, sales rose 3 percent.

Investors have been concerned that GE's targets for the oil business might be too rosy, given the slide in energy prices. But the unit's results held up better than some expected and GE backed its previous forecast for the year, which call for sales to drop as much as 5 percent.

GE shares dipped 0.1 percent to $27.26 in morning trading on the New York Stock Exchange, against broader declines for U.S. stocks.

Overall, GE posted a first-quarter net loss of $13.6 billion, or $1.35 per share. Results were weighed down by about $16 billion in charges tied to its exit of GE Capital assets. The company disclosed last week it was shedding much of its finance business.

Excluding special items, GE posted earnings of 31 cents per share, topping by 1 cent the average analyst estimate, according to Thomson Reuters I/B/E/S.

Sales in GE's oil and gas business dropped 8 percent, with profit down 3 percent. Excluding currency effects and the impact from deals, GE said its oil revenue was flat while operating profit rose 11 percent.

"On the oil and gas side, the revenues hung in there," said Tim Ghriskey, chief investment officer at Solaris Asset Management. But he cautioned, "The weakness in that business might still be ahead of it."

Total sales fell 12.5 percent to $29.34 billion, as GE Capital revenue slid 39 percent.

GE's industrial operating margins rose 1.2 percentage points to 14.6 percent from a year earlier, helped by administrative cost cuts and a greater mix of sales from higher-margin services.

Orders slipped 3 percent, although they were up slightly, excluding currency effects.

GE's shares soared the most in six years last Friday on the company's surprise announcement about GE Capital, pleasing investors who said the finance business weighed on GE's value as an industrial company. The stock is up 8 percent this year through Thursday.
