Co.'s primary business is the leasing of space on communications sites to wireless service providers, radio and television broadcast companies, wireless data providers, government agencies and municipalities and tenants in several other industries. Co. also provides tower-related services, including site application, zoning and permitting and structural analysis, which primarily support Co.'s site leasing business, including the addition of new tenants and equipment on its sites. We show 39 historical shares outstanding datapoints in our AMT shares outstanding history coverage, used to compute AMT market cap on those dates.|
Understanding the changing numbers of shares outstanding, the changing
share price, and the resulting changing AMT market cap history over the course of time is important for investors
interested in comparing AMT'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 AMT versus a peer is one thing; comparing
AMT 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 AMT can fluctuate over the course of history.
With this page we aim to empower investors researching AMT by allowing them to research the AMT market cap history.
