| About California Water Service Group (DE) |
| California Water Service Group is a holding company that provides water utility and other related services in California, Washington, New Mexico, Hawaii and Texas through its subsidiaries. Its business is conducted through its operating subsidiaries and provides utility services. Its business consists of the production, purchase, storage, treatment, testing, distribution, and sale of water for domestic, industrial, public, and irrigation uses, and the provision of domestic and municipal fire protection services. It provides wastewater collection and treatment services, including treatment which allows water recycling. We show 65 historical shares outstanding datapoints in our CWT shares outstanding history coverage, used to compute CWT market cap on those dates. Understanding the changing numbers of shares outstanding, the changing share price, and the resulting changing CWT market cap history over the course of time is important for investors interested in comparing CWT'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 CWT versus a peer is one thing; comparing CWT 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 CWT can fluctuate over the course of history.
