Intouch Holdings PCL (; formerly Shin Corporation) is a Thai holding company which focuses on telecommunication industry. It is the parent company of Advanced Info Service (AIS), the largest mobile phone operator in Thailand, and Thaicom, Thailand's satellite operator. It is listed in the Stock Exchange of Thailand and is part of SET50 index. The company was founded as "Shinawatra Computer Service and Investment" by Thaksin Shinawatra, who later became the Prime Minister of Thailand. The sale of Shinawatra family's stake in Shin Corporation to Singapore's Temasek Holdings in 2006 sparked controversy, which intensified the anti-Thaksin movement. Shin Corporation rebranded itself to Intouch in 2011, including its new stock symbol, but did not officially change its registered name until March 2014. History The early years, 1983–2006 The company was founded in 1983 as Shinawatra Computer by Thaksin Shinawatra, future Prime Minister of Thailand. The company changed its name in 1999, drawing the name "Shin" from the first four letters of Shinawatra's last name. The company grew tremendously under the leadership of Shinawatra. For its services it received the Royal Warrant on 11 June 2004, which gave it permission to display the royal Garuda emblem. Divestment and transition to InTouch PCL, 2006–2011 On 23 January 2006, the Shinawatra family sold its 49.6 percent stake in the company to nominees of Temasek Holdings, the Singapore government's investment arm, for US$1.88 billion. The 2006 sale of the Shinawatra family's share caused controversy in Thailand. The sale was in response to long-standing criticisms that the Shinawatra family's holdings created a conflict of interest for Thai Prime Minister Thaksin Shinawatra. Critics of the sale focused on allegations directed toward Thaksin and a compliant government that the transaction was exempt from capital gains tax, the fact that the Thai company was sold to a Singaporean company, and the fact that the Thai law regarding foreign investments in the telecom sector had been amended just prior to the sale. The company is linked by stock control to companies including Shin Satellite and Advanced Info Service. It also holds stakes in Thai AirAsia, a consumer finance company, and ITV, a local television station. The company's operations are divided into four lines of business: wireless telecommunications; satellite and international business; media and advertising; E-business.
