0138 GMT - Petronas Chemicals' 2H earnings will likely be supported by higher plant operating rates, although normalizing petrochemical prices and still-weak downstream demand may limit margin expansion, TA Securities analyst Luqman Anwar says in a note. Plant utilization is expected to recover to 80%-85% in 3Q and about 93% in 4Q following major turnarounds in 2Q, he notes. Fertilizer and methanol will likely remain the key earnings anchor, supported by resilient urea demand, food-security needs and tighter global supply, he reckons. However, a repeat of the sharp 2Q price surge is unlikely, while olefins and derivatives prices could face further pressure from weak demand and structural oversupply, he adds. TA Securities maintains a sell rating on Petronas Chemicals, keeps target price at 4.32 ringgit. Shares are 1.9% lower at 4.60 ringgit.
