KUALA LUMPUR – Axiata Group Bhd, the Malaysian parent company of mobile-phone operator Hello, may report “strong” fourth-quarter earnings growth, helped by demand for wireless broadband amid an improving economy, CIMB Investment Bank Bhd said Thursday. Earnings may “surprise on the upside”, CIMB said in a report. Net income more than doubled during the third quarter to 503.7 million ringgit (US$148 million) from 243.9 million ringgit. However, this performance was not matched at the firm’s Cambodia arm where Axiata recorded a 5 percent slide in revenues. The company cited increased competition for the second successive quarter of falling earnings.
