SSP, the travel concessions operator, has said like-for-like sales for its fourth quarter from 1 July to 30 September are expected to be up 3%.

Group revenues on a constant currency are set to increase by 14.8% - 17.5% at actual exchange rates.

The group said like-for-like sales growth in the air sector was driven by increased passenger numbers but trading in the rail sector has remained soft during the quarter.

Net contract gains in the fourth quarter are expected to be approximately 8.5%.

For the year to 30 September 2017, total group revenues are expected to increase by 11.4% on a constant currency basis, including like-for-like sales growth of approximately 3%, net contract gains of approximately 5.8% and a negative impact of -0.3% arising from the additional leap year day in 2016. At actual exchange rates, total group revenues are expected to increase by approximately 19.3% year-on-year.

On the outlook, the group said: “Looking forward, whilst a degree of uncertainty always exists around passenger numbers in the short term, particularly in the current environment, we are well placed to continue to benefit from the structural growth opportunities in our markets and to create further shareholder value.”
