Worldspan Group is forecasting gross profit of £1.47m to the end of June 2012, up from £1.36m in last year's audited accounts.
The North Wales-based agency – which is this year celebrating its 40th anniversary – has seen the growth result from an increase in existing clients’ activity, as well as new wins.
Managing director Sophie Morris said: "We have had such a strong twelve months and building on this momentum we are on track to grow further."
New clients include Vodafone – which carried out a UK event for 500 delegates in June.
Len Wilcock founded the agency in 1972. He told C&IT he was "so incredibly proud of what the company has achieved".
"While the scope and scale of the projects that we design and deliver has grown and evolved considerably, the excitement of delivering events is still as palpable as it was back in the early pioneering years of the UK events industry," added Wilcock.
Meanwhile, as part of Worldspan’s 40th anniversary celebrations, it has raised almost £4,000 for two of its charity partners – North Wales Cancer Care and the Missing Persons charity.
