Rapid Micro Biosystems, Inc. is a life sciences technology company that provides automation solutions for manufacturing and releasing healthcare products such as biologics, vaccines, cell and gene therapies, and sterile injectables. Its flagship Growth Direct system modernizes and automates outdated microbial quality control testing workflows in pharmaceutical manufacturing. The system supports four applications: Environmental Monitoring for the manufacturing environment, Water for purified water in drug production, In-Process Bioburden for raw materials and in-process products, and Sterility Release for final product testing before release. We show 21 historical shares outstanding datapoints in our RPID shares outstanding history coverage, used to compute RPID market cap on those dates.

Understanding the changing numbers of shares outstanding, the changing share price, and the resulting changing RPID market cap history over the course of time is important for investors interested in comparing RPID'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 RPID versus a peer is one thing; comparing RPID 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 RPID can fluctuate over the course of history. With this page we aim to empower investors researching RPID by allowing them to research the RPID market cap history.
