Well, isn’t that magnanimous of you!

Via that infallible source:

AT&T Inc. (originally the American Telephone and Telegraph Company) is an American multinationalconglomerateholding company that is Delaware-registered[5] but headquartered at Whitacre Tower in Downtown DallasTexas.[6] It is the world’s largest telecommunications company and the largest[7] provider of mobile telephone services in the U.S. As of 2020, AT&T was ranked 9th on the Fortune 500 rankings of the largest United States corporations, with revenues of $181 billion.[8]

Let’s do some math, shall we?

8 x $100 = $800

$800 / 181,000,000,000 = 0.00000000441989

Converting that into a percentage and rounding, gives us 0.0000004%.

That’s four 10 millionths of one percent. Mighty big of you AT&T.
