| About Public Service Enterprise Group Inc |
| Public Service Enterprise Group Incorporated is a regulated infrastructure company focused on a clean energy future. Co. principally conducts its business through two wholly owned subsidiaries, Public Service Electric and Gas Co. (PSE&G) and PSEG Power LLC (PSEG Power). Co.'s segments include PSE&G and PSEG Power. The PSE&G segment is engaged principally in the transmission of electricity and distribution of electricity and natural gas in certain areas of New Jersey. The PSE&G segment also invests in regulated solar generation projects and energy efficiency (EE) and related programs in New Jersey. We show 49 historical shares outstanding datapoints in our PEG shares outstanding history coverage, used to compute PEG market cap on those dates. Understanding the changing numbers of shares outstanding, the changing share price, and the resulting changing PEG market cap history over the course of time is important for investors interested in comparing PEG'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 PEG versus a peer is one thing; comparing PEG 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 PEG can fluctuate over the course of history. With this page we aim to empower investors researching PEG by allowing them to research the PEG market cap history. |
