The IT giant said the deal would significantly expand its presence in the hospitality sector.

New York-based TravelClick provides cloud-based software solutions, mainly to the hotel business.

It currently has more than 25,000 customers across 176 countries.

Amadeus said acquiring TravelClick’s portfolio would improve digital interaction with guests and reduce costs.

Luis Maroto, Amadeus president and chief executive, said TravelClick’s technology and broad customer base would allow it to provide the hospitality industry the tools it needs to grow.

“The combination of our two portfolios will allow us to provide that to hotels of all shapes and sizes across the world,” he said.

The deal takes TravelClick out of the hands of private equity owner Thomas Bravo.

It is expected to be completed during Q4 2018, subject to regulatory approval.

Around 1,100 TravelClick employees will join Amadeus as a result of the deal.

Francisco Perez-Lozao, Amadeus senior vice-president strategic growth businesses, added: “This is a huge step forward for Amadeus in hospitality. TravelClick gives us access to the mid-chain and independent hotel segment that makes up almost three-quarters of the market.

"We can now serve the entire industry with a very broad portfolio of solutions and we are looking for significant growth in the years ahead.”
