Liberty Global is one of the largest cable owners in Europe, with operations in the United Kingdom, Switzerland, Belgium (60%-owned), the Netherlands (50%-owned), Ireland, Poland, and Slovakia. The firm sold its businesses in Germany, Romania, Hungary, and the Czech Republic to Vodafone in 2019, generating $11 billion proceeds. An attempt to sell its Swiss business to rival Sunrise fell apart in 2019. The firm serves about 9.4 million Internet access customers across its consolidated footprint and another 3.4 million in the Netherlands, which it does not consolidate in its financial statements. Liberty also serves 6.4 million wireless customers in consolidated markets and 5.1 million in the Netherlands. The firm agreed to merge its U.K. business with wireless carrier O2 in May 2020.
