Meaning
Provisions in equity agreements designate the circumstances under which unvested shares or options become immediately exercisable. These acceleration rights often apply during a transition of corporate control or when a founder exits the firm under specific terms. The mechanic protects the initial team from being marginalized after a restructuring or buyout.
Trigger Event
Events that activate these provisions are typically grouped into single-trigger or double-trigger categories. A single trigger requires only a change of corporate control to execute the vesting shift. Double-trigger setups demand both a change in control and the termination of the individual’s employment without cause within a designated window.
This dual requirement prevents premature liquidity and ensures continuity of labor during transition periods.
Vesting Velocity
The rate of accelerated vesting varies from partial adjustments to immediate and total distributions of remaining options. A partial acceleration might release twenty-five percent of the remaining unvested equity. In contrast, full acceleration grants the holder immediate ownership of their entire remaining equity pool.
This variable rate dictates the financial leverage of a departing founder during buyout negotiations.
Capital Impact
Company valuation and cap table structures shift when these clauses are executed. Outstanding options convert into common stock, which increases the total share count and dilutes other holders. This sudden dilution can alter the acquisition price or the net payout received by the purchasing entity.
