(Telecompaper) Indonesian mobile operator XL Axiata posted a nine-month profit of IDR 917 billion, down 58 percent from IDR 2.20 trillion a year earlier as revenues fell 9 percent year-on-year and Opex increased by 14 percent. Normalised net profit, excluding forex losses and accelerated depreciation in Sumatra, Java, and Bali, fell 35 percent to IDR 1.50 trillion.

Opex rose 14 percent to IDR 9.39 trillion and EBITDA fell 14 percent to IDR 6.42 trillion, largely on the introduction of SMS interconnect and expansion of leased sites impacting infrastructure costs. EBITDA margin slipped 7 percentage points to 40 percent. XL ended the nine-month period with 58.1 million mobile subscribers, up 37 percent from September a year earlier, but saw blended ARPU fall to IDR 27 from IDR 31. For the full financial year, XL expects revenue growth in the low-single digits and an EBITDA margin in the low 40s.
