Value an equity grant across vesting with exercise cost and dilution.
Nothing vests before the cliff, after which the accrued portion vests immediately. Options are only worth the spread above the strike price, so a grant can be worthless despite a large share count. Quoted equity values usually ignore both dilution and exercise cost, which together can halve the realisable value of a grant at an early stage company.
