| About AECOM |
| AECOM is an infrastructure consulting company, providing professional services throughout the project lifecycle. Co.'s business is focused primarily on providing fee-based knowledge-based services. Co.'s segments include Americas, International and AECOM Capital (ACAP). The Americas segment provides planning, consulting, architectural and engineering design, construction management and program management services to public and private clients in the U.S., Canada, and Latin America. We show 67 historical shares outstanding datapoints in our ACM shares outstanding history coverage, used to compute ACM market cap on those dates. Understanding the changing numbers of shares outstanding, the changing share price, and the resulting changing ACM market cap history over the course of time is important for investors interested in comparing ACM'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 ACM versus a peer is one thing; comparing ACM 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 ACM can fluctuate over the course of history. With this page we aim to empower investors researching ACM by allowing them to research the ACM market cap history. |
