European countries, later selling some of its stations to local operators. In 2014, Communicorp expanded to the United Kingdom, acquiring eight radio stations across the country; in 2017, Communicorp moved its UK radio stations to a new independent company, Communicorp UK, of which O'Brien owns 98% of the shares. In February 2021, O'Brien sold Communicorp to Bauer Media Audio for approximately €100 million. Esat Telecom and Esat Digifone In 1991, O'Brien formed a telecommunications consortium called Esat Telecom to compete with the state-owned Telecom Eireann. In partnership with Telenor, Norway's state telecom operator, Esat formed Esat Digifone, which made a successful bid for Ireland's second GSM mobile licence. Circumstances around the awarding of the licence to Esat Digifone became the subject of the Moriarty Tribunal. On 7 November 1997, Esat Telecom Group plc held an initial public offering and was listed on the Irish Stock Exchange, London Stock Exchange, and NASDAQ. In 2000, Telenor made a bid for control of the company, but O'Brien sold it to BT, reportedly making €250 million from the sale. Aergo Capital In 1999, O'Brien co-founded aircraft leasing company Aergo Capital, of which he owned an 80% stake. From its inception until 2014, Aergo traded more than 150 aircraft with a gross value of over €791 million (approximately $1 billion). In October 2014, O'Brien and his partner, Fred Browne, sold the company to CarVal, a US investment firm; Browne remained with the new company as CEO. Independent News & Media In the late 2000s, O'Brien began purchasing shares of Independent News & Media (INM), ultimately spending an estimated €500 million to amass a 29.9% stake in the company. O'Brien clashed with the company's board, especially former owner Tony O'Reilly, who stepped down from his position as CEO in 2009 and sold most of his INM shares in 2014. In April 2019, O'Brien and Dermont Desmond, INM's second largest shareholder at the time, sold their shares to the Belgian media group Mediahuis; O'Brien reportedly received €43.5m as part of the deal. Although he never owned a majority stake in INM, O'Brien was at times accused of exerting significant influence at the company. In 2014, allegations arose that Stephen Rae, a group editor at INM, ordered amendments to a column by Sunday Independent editor Anne Harris that contained references to O'Brien. In 2015, Paul Meagher, a solicitor for O'Brien, reportedly called INM solicitor Simon McAleese in 2012
