2019 ANNUAL REPORT 74384.indd 1 3/13/20 1:04 PM Bauxite Alcoa is among the world’s largest bauxite producers, and we operate with effi cient and sustainable mining practices, including environmental management through biodiversity initiatives and stakeholder engagement. With ownership in seven active bauxite mines globally, we maintain a fi rst-quartile cost position with reserves located near strategic markets, supplying both our own internal refi nery system and third-party customers. In 2019, this segment set annual production records. PRODUCTION: 47.4 million dry metric tons TOTAL SHIPMENTS: 47.6 million dry metric tons 3RD-PARTY SHIPMENTS: 6.2 million dry metric tons TOTAL REVENUE: $1.3 billion ADJUSTED EBITDA MARGIN: 39.5% Alumina We are the world’s largest alumina producer outside of China and maintain a fi rst quartile cost position. We have a competitive advantage due to our proprietary technology, process automation, and a highly skilled workforce. Our refi neries use high-quality bauxite, enabling peak effi ciency. Most of our alumina is sold to external customers for metallurgical applications. In 2019, this segment set annual production records. PRODUCTION: 13.3 million metric tons TOTAL SHIPMENTS: 13.5 million metric tons 3RD-PARTY SHIPMENTS: 9.5 million metric tons TOTAL REVENUE: $4.8 billion ADJUSTED EBITDA MARGIN: 22.8% Aluminum Our aluminum portfolio is comprised of smelting, casting, rolling, and energy assets, and is focused on being competitive through all market cycles. Most of our smelters are powered by renewable, hydro-electric generation under long-term contracts. We produce a variety of products, including value-added castings in diverse shapes and alloys, many of which were developed and patented by Alcoa.

The process of restarting the smelter is underway and should be completed in the second quarter of 2020, restoring the smelter to Alcoa’s full operating capacity of 310,000 metric tons. During 2019, we also completed the divestiture of the historically unprofi table Avilés and La Coruña smelting facilities in Spain after reaching an agreement with the workers’ representatives at these two facilities. Focused on the long-term Financially, 2019 was a challenging year. We fi nished Roy C. Harvey and Michael G. Morris the year with a net loss of $1.1 billion.
