A major European hotel operator has filed for insolvency, casting doubt over the future of its establishments throughout the continent. Revo Hospitality Group, formerly known as HR Group, was established in 2008 and is Europe's largest white-label hotel operator - a third-party management company that oversees hotels for owners without featuring its own branding.

The business operates more than 260 hotels across 12 European countries and 146 cities. Last week, it announced intentions for restructuring through self-administration by summer, while confirming that hotels in two nations would remain operational.

The company stated: "Around 140 companies belonging to the Revo Hospitality Group have filed for insolvency under their own management at Charlottenburg District Court. The approximately 125 hotels in Germany and Austria will continue to operate with all 5,500 employees. The proceedings will be supervised by court-appointed administrators."

The group includes numerous hotels trading under prominent franchise names such as Hilton and ibis Styles, as well as its own brands, including Hyperion, reports the Express.

Establishments can be found throughout Switzerland, France, the Netherlands, Czech Republic, Italy, Poland and Spain. The majority of Revo Hospitality's hotels are based in Germany.

Revo Hospitality highlighted rising costs as a major burden on the business when it confirmed the insolvency proceedings last week. The firm stated in a press release: "With the economic crisis, 140 companies, including the management and holding company, got into difficulties.

"In particular, increased wage costs and the sharp rise in minimum wages, but also higher costs for rent, energy and food, are weighing on the business. Above all, the strong expansion of the Revo Hospitality Group in recent years led to duplicate structures and integration problems." The hotel chain purchased its first property in Leipzig, Germany, in 2008.

It ran 51 hotels in 2020 but grew swiftly in the following years, producing €1.3billion (approximately £1.1billion) in yearly revenue and employing around 8,300 personnel throughout Europe, according to reports. The group said: "The acquisition of the new hotels involved considerable costs. On the other hand, the number of overnight stays did not increase as expected and the planned turnover for 2025 was not achieved." Specialists have been enlisted to steady operations and develop a restructuring strategy.
