| About Perma-Fix Environmental Services, Inc. |
| Perma-Fix Environmental Services, Inc. is a nuclear services company and a provider of nuclear and mixed waste management services. It operates through two segments: Treatment and Services. The Treatment Segment includes nuclear, low-level radioactive, mixed waste, hazardous and non-hazardous waste treatment, processing, and disposal; and research and development (R&D) activities to identify, develop and implement innovative waste processing techniques for problematic waste streams. We show 48 historical shares outstanding datapoints in our PESI shares outstanding history coverage, used to compute PESI market cap on those dates. Understanding the changing numbers of shares outstanding, the changing share price, and the resulting changing PESI market cap history over the course of time is important for investors interested in comparing PESI'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 PESI versus a peer is one thing; comparing PESI 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 PESI can fluctuate over the course of history. With this page we aim to empower investors researching PESI by allowing them to research the PESI market cap history. |
