| About Alcoa Corporation |
| Alcoa Corporation is a vertically integrated aluminum company, which is engaged in bauxite mining, alumina refining, aluminum production (smelting and casting) and energy generation. Its Alumina segment consists of its worldwide refining system, which processes bauxite into alumina. The alumina produced by this segment is sold to internal and external aluminum smelter customers; a portion of the alumina is sold to external customers who process it into industrial chemical products. Its Aluminum segment consists of worldwide smelting and cast house system, which processes alumina into primary aluminum, and portfolio of energy assets in Brazil, Canada and the U.S.. We show 39 historical shares outstanding datapoints in our AA shares outstanding history coverage, used to compute AA market cap on those dates. Understanding the changing numbers of shares outstanding, the changing share price, and the resulting changing AA market cap history over the course of time is important for investors interested in comparing AA's market cap history versus its peers. Many "beginner" or "novice" investors will look at one stock trading at a price of $10 per share and another trading at a price of $20 per share and think the latter company is worth twice as much. Of course, that is a completely meaningless comparison without also knowing how many shares outstanding there are for each of the two companies, and then calculating their respective market caps. Comparing the share price of AA versus a peer is one thing; comparing AA market cap versus a peer is a completely different story. Furthermore, via fluctuation both in per-share price and in the number of shares outstanding (via issuance of new shares over time, the repurchase of existing shares), the market cap for a company like AA can fluctuate over the course of history. With this page we aim to empower investors researching AA by allowing them to research the AA market cap history. |
