United States Steel is a producer and seller steel products, including flat-rolled and tubular products, in North America and Europe. Co. is also engaged in other business activities consisting primarily of railroad services and real estate operations. Co. has three reportable operating segments: North American Flat-Rolled, which includes the operating results of Co.'s integrated steel plants and equity investees; U.S. Steel Europe, which includes Co.'s subsidiary, U.S. Steel Kosice, its steel plant and coke production facilities in Slovakia, and its subsidiaries; and Tubular Products, which includes Co.'s tubular production facilities and an equity investee. We show 51 historical shares outstanding datapoints in our X shares outstanding history coverage, used to compute X market cap on those dates.

Understanding the changing numbers of shares outstanding, the changing share price, and the resulting changing X market cap history over the course of time is important for investors interested in comparing X'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 X versus a peer is one thing; comparing X 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 X can fluctuate over the course of history. With this page we aim to empower investors researching X by allowing them to research the X market cap history.
