Should kickoff have a hyphen

The Word "kickoff" is typically written as a single Word without a hyphen when used as a noun or verb, as in "The kickoff is at noon" or "We will kickoff the event." However, it can be hyphenated as "kick-off" when used as a compound adjective, such as in "kick-off meeting." Overall, the usage depends on context, but the single-Word form is more common.
