| About Atomera Inc |
| Atomera Incorporated is engaged in the business of developing, commercializing and licensing processes and technologies for the semiconductor industry. Co.'s lead technology, named Mears Silicon Technology (MST), is a thin film of reengineered silicon, typically 100 to 300 angstroms (or approximately 20 to 60 silicon atomic unit cells) thick. MST can be applied as a transistor channel enhancement to complementary metal-oxide semiconductor (CMOS)-type transistors. MST can be incorporated into the common types of semiconductor products, including analog, logic, optical and memory integrated circuits. We show 16 historical shares outstanding datapoints in our ATOM shares outstanding history coverage, used to compute ATOM market cap on those dates. Understanding the changing numbers of shares outstanding, the changing share price, and the resulting changing ATOM market cap history over the course of time is important for investors interested in comparing ATOM'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 ATOM versus a peer is one thing; comparing ATOM 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 ATOM can fluctuate over the course of history. With this page we aim to empower investors researching ATOM by allowing them to research the ATOM market cap history. |
