Sabre is to buy the Trust Group for $154 million, a deal that will include mothership Trust International, InnLink and Nexus.
Trust International is the well-known reservation system provider for hotel chains, with InnLink running similar services for independent hotels, and RFP and sales technology coming via Nexus.
The deal ends two and a half years for the Trust Group under the ownership of venture capital giant Battery Ventures, which took over running of the company in June 2013 from Kings Park Capital.
Sabre says the deal, which is expected to close in the first quarter of 2016, will allow it to "provide a comprehensive SaaS platform" to hoteliers, whilst extending its existing position as a central reservation system provider.
As a combined entity, Sabre claims the pair will serve "serve significantly more hotels than any other central reservations technology provider".
Sabre president and CEO Tom Klein previously talked in June this year about further software company acquisitions, with any such deals expected to come in at the $10 million to $130 million range.
On the Trust deal, he says:
"Acquiring the Trust Group is consistent with our stated goal of building on Sabre Hospitality Solutions' global leadership position, and this combination will enable us to grow faster.
"The Trust Group is one of the industry's most respected brands, and our customers will benefit from our combined expertise and focus on innovation."
The acquisition is likely to add some $40 million a year in incremental revenue to Sabre during 2016.
Trust CEO Richard Wiegmann adds:
"This combination will help accelerate our customers' growth through a broader set of hospitality solutions and services that will better serve the evolving needs of hotels and their guests."
InnLink and its sister tech provider TravelLynx are only a relatively new parts of the Trust portfolio, having being bought for an undisclosed fee in April 2014.
The deal brings Sabre's acquisition spree so far in 2015 to around $565 million, having bought out the remaining shares in Asia-Pacific distribution service Abacus for $411 million in May.
Hospitality tech and distribution are clearly seen as a significant playgrounds to dabble for the traditional global distribution systems, with Sabre buying reservation platform and revenue management tech provider Genares in September 2014.
Travelport purchased hospitality distribution provider Hotelzon for $10 million in June 2014.
Both Sabre and Travelport's investments in other companies are still dwarfed by the $500 million paid by Amadeus to acquire Newmarket International, the hospitality IT company, in December 2013.
