Singtel's 8% drop in profits in Q3 was due to the 14% decline in its associates’ net profit contribution to $420m.

RHB Research added that the regional mobile associates fell for the second consecutive quarter by 16% with the key drags from Telkomsel (-11%) and Airtel (-53%), partly mitigated by Advanced Info Service (AIS) (+6%).
