Alcoa Corporation expects alumina shipments from its Pinjarra refinery in Western Australia to decline by approximately 120,000 tonnes in the second quarter compared with the first quarter after Cyclone Narelle disrupted LNG supplies in March. The refinery, which has an annual alumina production capacity of 4.7 million tonnes, is expected to incur an additional USD30 million in production costs during the quarter. Alcoa also expects around USD15 million in extra fuel costs at its São Luís alumina refinery in Brazil due to ongoing Middle East tensions. The company noted that its alumina business is facing pressure from weak alumina prices and lower-quality bauxite supplies in Western Australia. Following the update, Alcoa shares fell 9.5%.
