| About CMS Energy Corp |
| CMS Energy Corporation is an energy company operating primarily in Michigan. Co. manages its businesses by the nature of services each provides, and operates principally in three segments: Electric Utility, Gas Utility, and NorthStar Clean Energy. The Electric Utility segment consists of regulated activities associated with the generation, purchase, distribution, and sale of electricity in Michigan. The Gas Utility segment consists of regulated activities associated with the purchase, transmission, storage, distribution, and sale of natural gas in Michigan. We show 49 historical shares outstanding datapoints in our CMS shares outstanding history coverage, used to compute CMS market cap on those dates. Understanding the changing numbers of shares outstanding, the changing share price, and the resulting changing CMS market cap history over the course of time is important for investors interested in comparing CMS'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 CMS versus a peer is one thing; comparing CMS 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 CMS can fluctuate over the course of history. With this page we aim to empower investors researching CMS by allowing them to research the CMS market cap history. |
