| About IGM Biosciences Inc |
| IGM Biosciences, Inc. is a clinical-stage biotechnology company. Co. is engaged in developing and delivering a new class of medicines to treat patients with cancer and autoimmune and inflammatory diseases. Co.'s pipeline of clinical and preclinical assets is based on the IgM antibody, which has 10 binding sites compared to conventional IgG antibodies with only two binding sites. It is also focused on creating, developing, manufacturing, and commercializing IgM antibody agonists against oncology and immunology and inflammation targets. Co.'s development programs include Aplitabart, Imvotamab, and IGM-2644. We show 21 historical shares outstanding datapoints in our IGMS shares outstanding history coverage, used to compute IGMS market cap on those dates. Understanding the changing numbers of shares outstanding, the changing share price, and the resulting changing IGMS market cap history over the course of time is important for investors interested in comparing IGMS'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 IGMS versus a peer is one thing; comparing IGMS 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 IGMS can fluctuate over the course of history. With this page we aim to empower investors researching IGMS by allowing them to research the IGMS market cap history. |
