| About H2O America |
| SJW Group is a water and wastewater utilities company providing water service. Co. operates through four wholly owned subsidiaries, namely, San Jose Water Co. (SJWC), SJWNE LLC, SJWTX Holdings, Inc., and SJW Land Co.. SJWNE LLC is a special purpose entity holding company for Connecticut Water Service, Inc. (CTWS) (and its wholly owned subsidiaries, The Connecticut Water Co. (CWC), The Maine Water Co. (MWC), Chester Realty, Inc. and New England Water Utility Services, Inc. (NEWUS)). SJWTX Holdings, Inc. is the holding company for SJWTX, Inc., doing business as The Texas Water Co. (TWC), Texas Water Operation Services, LLC (TWOS) and Texas Water Resources, LLC (TWR). We show 6 historical shares outstanding datapoints in our HTO shares outstanding history coverage, used to compute HTO market cap on those dates. Understanding the changing numbers of shares outstanding, the changing share price, and the resulting changing HTO market cap history over the course of time is important for investors interested in comparing HTO'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 HTO versus a peer is one thing; comparing HTO 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 HTO can fluctuate over the course of history. With this page we aim to empower investors researching HTO by allowing them to research the HTO market cap history. |
