Significant contract losses they are referring to i think are;
- Suncorp Stadium, not sure of details;
- Rio camps, estimated to be 400m revenue pa(1), EBITDA Margin is reported at 16% for Base and Townships, so that could be upto $64m reduction to EBITDA, but i think in an earnings call they said they might get some of that back, for example they have a pretty dominate position in commercial laundries in WA, and Sodexo (the contract winner) aren't likely to set-up a commercial laundry.
The one-off's in the first half last year reported in the market update in Dec15 were $80m EBITDA (2), so i guess just on that EBITDA is looking like it will be similar to last year. Revenue should increase in the second half due to some PPP's starting up, and Nuvo.
