Earlier quoted context omitted.
In financial theory, enterprise value corresponds to the sum of all discounted cash flows (after tax). Thus, it is the market's best estimate for the value of the business. The question of capital structure should not really matter according to the Miller-Modigliani theorem.
The value of a business is what someone would be willing to pay for control over it, or its market cap (value of all shares). This is typically disconnected from its DCF which is a modelled value based on expected future returns. Enterprise value is also market cap + net debt, not its cumulative present value DCFs.

It isn't the EV either, though
