For each tranche, vesting also requires that the average volume-weighted stock price over any 30 consecutive trading days within five years of grant meets separate hurdles of $7.50, $12.50, or $20.00.

If the relevant stock price threshold for a tranche is not reached within five years from the grant date, none of the options in that tranche will vest and they will terminate at the end of that five-year period. These are compensation-related grants rather than open-market purchases.
