Lockheed Martin Corp (LMT.N) on Tuesday announced a $5 billion tax-free deal to combine its information systems and government services business with Leidos Holdings Inc (LDOS.N), and forecast a lower-than-expected profit in 2016. Lockheed’s shares fell as much as 5 percent amid confusion over future prospects for the Pentagon’s No. 1 supplier, although the stock recovered after Lockheed officials reassured analysts they still expected rising sales and earnings in coming years. Lockheed was down 0.8 percent to $209.25.
