(dollars in millions, except per-share amounts, average realized prices, and average cost amounts) The Company Alcoa Corporation, a Delaware corporation (Alcoa or the Company) which became an independent, publicly traded company on November 1, 2016, is active in all aspects of the upstream aluminum industry with bauxite mining, alumina refining, and aluminum smelting and casting. The Company has direct and indirect ownership of 25 operating locations across eight countries on five continents. The Company’s operations are comprised of two reportable business segments: Alumina and Aluminum. The Alumina segment primarily consists of the Company’s bauxite mines and alumina refineries, and its operations generally include the mining of bauxite and other aluminous ores, as well as the refining, production, and sale of smelter grade and non-metallurgical alumina. The Aluminum segment consists of the Company’s aluminum smelting and casting operations along with most of the Company’s energy production assets. Aluminum, as an element, is abundant in the earth’s crust, but a multi-step process is required to manufacture finished aluminum metal. Aluminum metal is produced by refining alumina oxide from bauxite into alumina, which is then smelted into aluminum and can be cast into many shapes and forms. Alcoa smelts and casts aluminum in various shapes and sizes for global customers, including developing and creating various alloy combinations for specific applications. Aluminum metal is a commodity traded on the London Metal Exchange (LME) and priced daily.
