There are lots of US companies that pay dividends. Another commentor lists some tech companies that do, and there are lots of other types of businesses that do. A quick internet search will give you a list.

You are correct that stock buybacks are another way that companies reward their shareholders.

Good call. I should have said that most of those companies also do buybacks as part of their capital return strategies.

And, as an investor I absolutely prefer buybacks so I can control my tax liability.
