| AT&T is a holding company. Through its subsidiaries, Co. is a provider of telecommunications, media and technology services globally. Co. has four reportable segments: Communications, which provides wireless and wireline telecom, video and broadband services to consumers located in the U.S. or in U.S. territories and businesses globally; WarnerMedia, which includes media and entertainment businesses that principally develop, produce and distribute feature films, television content, and other content globally; Latin America, which provides entertainment services in Latin America and wireless services in Mexico; and Xandr, which develops digital advertising services. We show 40 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.
