ASX ANNOUNCEMENT Alumina NPAT US $ 73.6 million Interim dividend 3.4 US cents per share ● Significant shipping disruptions and higher freight costs constrained alumina prices Alumina generates solid returns through half Alumina Limited ( ASX : AWC ) ( " Alumina ” or “ Company " ) today reported a statutory net profit after tax of US $ 73.6 million for the half - year to 30 June 2021. The Company declared an interim , fully franked dividend of 3.4 US cents per share . Alumina's Chief Executive Officer , Mike Ferraro , said , " In challenging market conditions , Alumina Limited has been able to increase its dividend to shareholders by 21 percent . " AWAC's low - cost assets were able to produce record bauxite and alumina outputs for a half year . Realised alumina prices were higher but API was constrained by significantly higher freight costs contributed to by global shipping disruptions . In addition , returns were offset by higher costs due to currency movements and unplanned outages . However , AWAC's cash costs continue to remain in the lowest quartile of the global cost curve and our alumina refinery portfolio has the lowest CO2 emissions intensity amongst major refiners . Securing new energy contracts for the Portland smelter to underpin its operations has been positive for the employees , community and the Company . ALUMINA " Primary aluminium demand has recovered in 2021 and prices are at multi - year highs . We expect ex - China aluminium production to increase in the second half to meet demand and this will be positive for alumina prices . In addition , we expect to see the non - China alumina surplus to contract which should further positively impact alumina prices .
