| About Koppers Holdings Inc |
| Koppers Holdings Inc. is an integrated global provider of treated wood products, wood preservation chemicals and carbon compounds. Co. operates through three segments: Railroad and Utility Products and Services (RUPS), Performance Chemicals (PC) and Carbon Materials and Chemicals (CMC). Its RUPS segment sells treated and untreated wood products, rail joint bars and services primarily to the railroad markets in the U.S. and Canada and treated wood products and services to the utility markets. We show 66 historical shares outstanding datapoints in our KOP shares outstanding history coverage, used to compute KOP market cap on those dates. Understanding the changing numbers of shares outstanding, the changing share price, and the resulting changing KOP market cap history over the course of time is important for investors interested in comparing KOP'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 KOP versus a peer is one thing; comparing KOP 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 KOP can fluctuate over the course of history. With this page we aim to empower investors researching KOP by allowing them to research the KOP market cap history. |
