EBITDA vs Profit
EBITDA is not a profit measure, it is used to compare different company results on a like for like basis. The report and accounts clearly state that the aviation division made a loss not a profit. The costs are almost all in SEN and not CAX so it is SEN that is the overall loss maker. As for the internal rent, apply that amount to the £100m+ that Stobart invested in the airport and you will see why the payback period on that investment is still in excess of 100 years.
As I stated previously, the loss in the period is less than the previous period's loss, however it is still a loss. You cannot interpret the accounts in any other way.
