I am assuming, and I could be very wrong, that Wonder is smaller by market cap than Grubhub.

In this case, GrubHub had taken on a bunch of debt; Wonder agreed to assume it, and GrubHub's owners/investors get $150M in cash.
Private companies have shares. Given a per-share price, you can get a market cap. For a company with debt, like GrubHub, enterprise value is a better metric.
how do you know the per-share price
Same way you do for a public company. From trades and valuations. Private shares exchange hands in private transactions as well as almost every time the company raises money. If a company issues incentive stock options, they're required to calculate a 409A price, which while a bullshit number, is indeed a per-share price.
Corporations, by law, have shares.
