| About Janus International Group Inc |
| Janus International Group, Inc. is a global manufacturer and supplier of turn-key self-storage, commercial and industrial building solutions. It operates through two geographic segments: Janus North America and Janus International. The Janus North America segment is comprised of all the other entities, including Janus International Group, LLC, Betco, Inc., Noke, Inc., Asta Industries, Inc., DBCI, LLC, Access Control Technologies, LLC, Janus Door, LLC, and Steel Door Depot.com, LLC. The Janus International segment is comprised of Janus International Europe Holdings Ltd. (UK). Its production and sales are in Europe and Australia. We show 7 historical shares outstanding datapoints in our JBI shares outstanding history coverage, used to compute JBI market cap on those dates. Understanding the changing numbers of shares outstanding, the changing share price, and the resulting changing JBI market cap history over the course of time is important for investors interested in comparing JBI'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 JBI versus a peer is one thing; comparing JBI 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 JBI can fluctuate over the course of history. With this page we aim to empower investors researching JBI by allowing them to research the JBI market cap history. |
