Serko, an Australasian leader in online travel booking and expense management for business, announced earlier that it has acquired the business and assets of Arnold Travel Technology.

The all-cash deal sees the company move from Wotif Group, a leading operator of travel brands in the Asia-Pacific region and part of the Expedia group.

Assuming retention of the majority of Arnold’s existing client base, Serko expects this transaction to result in an uplift in revenues for the six months to September 30th 2015 in the range of seven to eight per cent, however EBITDA will not change materially for that period.

Serko expects the transaction to deliver a positive contribution to EBITDA in the second half of the financial year 2016.

The acquisition is expected to increase Serko’s Australasian transactional volume by a minimum of 20 per cent, based on current monthly transaction volumes, and was completed for a confidential nominal sum.

Darrin Grafton, Serko’s chief executive officer said: “This is an important strategic investment for Serko given we now expect around USD $4 billion of Australia’s corporate travel spend to be booked through Serko’s platforms.”

He continued: “Through this transaction and our ongoing relationship with Expedia, we’re able to continue to serve Arnold’s corporate customers and government accounts, significantly grow our business and to affirm our commitment to our TMC resellers, which we maintain are crucial to our ongoing success in the region.”
