| AT&T is a holding company. Through its subsidiaries, Co. is a provider of communications and digital entertainment services in the U.S. and the world. Co. has four segments: Business Solutions, which provides services to business customers and individual subscribers who purchase wireless services through employer-sponsored plans; Entertainment Group, which provides video, internet, voice communication, and interactive and targeted advertising services; Consumer Mobility, which provides nationwide wireless services to consumers and wholesale and resale wireless subscribers; and International, which provides entertainment services in Latin America and wireless services in Mexico. We show 36 historical shares outstanding datapoints in our T shares outstanding history coverage, used to compute T market cap on those dates.|
Understanding the changing numbers of shares outstanding, the changing
share price, and the resulting changing AT and T market cap history over the course of time is important for investors
interested in comparing AT and T'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 AT and T versus a peer is one thing; comparing
AT and T 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 AT and T can fluctuate over the course of history.
With this page we aim to empower investors researching AT and T by allowing them to research the AT and T market cap history.
