Lockheed Martin shares fall as cash flow outlook disappoints

The outlook for annual cash flow was the only major financial category that Lockheed did not revise higher."There could be some modest disappointment that the cash guidance has not been raised, but it is early in the year and cash is trickier to predict," analyst Robert Stallard of Vertical Research said in a note.The dispute centres around whether Lockheed or its customer should pay what a source said was $118 million to fix a corrosion issue discovered last year.
