| About Plug Power Inc |
| Plug Power Inc. offers a comprehensive green hydrogen ecosystem, covering production, storage, delivery, and energy generation, to support customer business goals. Co. develops viable hydrogen and fuel cell solutions and provides electrolyzers for on-site hydrogen generation at refineries, chemical, steel, fertilizer producers and refueling stations. Focused on industrial mobility, it powers electric forklifts and vehicles and supports critical operations with stationary power systems for data centers, microgrids and other facilities, replacing batteries, diesel generators, or the grid for various industries. We show 64 historical shares outstanding datapoints in our PLUG shares outstanding history coverage, used to compute PLUG market cap on those dates. Understanding the changing numbers of shares outstanding, the changing share price, and the resulting changing PLUG market cap history over the course of time is important for investors interested in comparing PLUG'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 PLUG versus a peer is one thing; comparing PLUG 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 PLUG can fluctuate over the course of history. With this page we aim to empower investors researching PLUG by allowing them to research the PLUG market cap history. |
