UPDATE 1-Jabil quarterly revenue rises 27 percent

(Updates with details, background, share price)

SAN FRANCISCO, March 22 (Reuters) - Electronics contract manufacturer Jabil Circuit Inc. (JBL.N) posted on Thursday a 27-percent rise in second-quarter revenue but gave an earnings forecast below expectations, and its shares fell.

Jabil said restructuring costs meant third-quarter earnings would be between a loss of 8 cents per share and a profit of 4 cents per share, well below the 39-cent profit that was the average of six forecasts on Reuters Estimates.

The restructuring costs would be at the high end of the previously estimated range of $200 million to $250 million, with an impact of between 13 cents and 19 cents per share for the third quarter, Jabil said.

Jabil said third-quarter revenue would be between $2.9 billion and $3 billion, below the $3.04 billion average analyst estimate.

The second-quarter revenue of $2.9 billion was ahead of the average Wall Street forecast of $2.83 billion.

Shares in Jabil fell 2.9 percent to $24.20 in extended trading after the earnings release. That came on top of a decrease of 4.1 percent in regular trading on the New York Stock Exchange.

The company did not post detailed financial information for the second quarter because of an ongoing review of its historical financial reports.
