| About Regeneron Pharmaceuticals, Inc. |
| Regeneron Pharmaceuticals, Inc. is a fully integrated biotechnology company. Co. invents, develops, manufactures, and commercializes medicines for people with serious diseases. Its products and product candidates in development are designed to help patients with eye diseases, allergic and inflammatory diseases, cancer, cardiovascular and metabolic diseases, neurological diseases, hematologic conditions, infectious diseases, and rare diseases. We show 65 historical shares outstanding datapoints in our REGN shares outstanding history coverage, used to compute REGN market cap on those dates. Understanding the changing numbers of shares outstanding, the changing share price, and the resulting changing REGN market cap history over the course of time is important for investors interested in comparing REGN'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 REGN versus a peer is one thing; comparing REGN 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 REGN can fluctuate over the course of history. With this page we aim to empower investors researching REGN by allowing them to research the REGN market cap history. |
