Indonesia’s largest fixed and mobile telecoms operator, PT Telekomunikasi Indonesia (Telkom), yesterday reported a net profit of IDR3.58 trillion (USD388.5 million) in the April-June period, up 51.9% from IDR2.36 trillion a year ago, according to Reuters calculations, while revenue rose 25.5% to IDR15.28 trillion. The firm only released first-half data, but is estimated to have recorded a 50% rise in its second quarter net profit, led by strong growth in its mobile phone business. Telkom, the largest company on the Jakarta stock exchange with a market capitalisation of USD23.1 billion, owns a 65% stake in Indonesia’s largest mobile player, PT Telekomunikasi Selular (Telkomsel). The wireless arm added around eight million new users in 1H 2007, lifting its total to 42.8 million, and eclipsing the full-year target of 42 million. Sales from mobile operations rose 18% in the three months to 30 June compared with a year ago, to IDR5.82 trillion.
