UPDATE 2.30pm: Shares in OTOC have taken off after the mine camp builder released a full-year forecast showing a stronger performance in the second half.
OTOC said it expected to have earnings before interest and tax of $7 million from revenue of $158 million.
The figures are based on internal management accounts and subject to finalisation of accounts. They do not include the costs of OTOC's merger with the Emerson Stewart Group last year and corporate overheads.
The company's shares closed up two cents, or 25 per cent, at 10 cents.
"These results represent a marked improvement over the December half and reflect recent initiatives to better monitor revenue and costs at a project level, as well as our strong competitive position," chief executive Adam Lamond said.
"We are particularly pleased that both OTOC Australia and Whelans expect to exceed guided revenue and report strong EBIT figures, combined with a solid order book for 2013."
