| About Compass Minerals International Inc |
| Compass Minerals International, Inc. is a provider of essential minerals focused on safely delivering where and when it matters to help solve nature's challenges for customers and communities. Co.'s segments include Salt and Plant Nutrition. The Salt segment produces and markets salt, consisting of sodium chloride and magnesium chloride, for use in road deicing for winter roadway safety and for dust control, food processing, water softeners and other consumer, agricultural and industrial applications. The Salt segment provides highway deicing salt to customers in North America and the United Kingdom. We show 65 historical shares outstanding datapoints in our CMP shares outstanding history coverage, used to compute CMP market cap on those dates. Understanding the changing numbers of shares outstanding, the changing share price, and the resulting changing CMP market cap history over the course of time is important for investors interested in comparing CMP'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 CMP versus a peer is one thing; comparing CMP 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 CMP can fluctuate over the course of history. With this page we aim to empower investors researching CMP by allowing them to research the CMP market cap history. |
