Meaning
Contractual provisions within an equity agreement allow for the immediate maturation of vesting schedules upon the occurrence of a predefined trigger event. The presence of an acceleration clause modifies the standard timeline for ownership, granting the holder full or partial rights to their shares before the original service period concludes.
Trigger Mechanism
Activation typically occurs during a change in corporate ownership or the termination of a founder without cause. Single trigger arrangements activate upon the sale of the company alone, while double trigger configurations require both a sale and a subsequent loss of employment.
Economic Shift
Shortening the vesting schedule increases the immediate liquidity available to a person while reducing their long-term incentive to remain in an operational seat. This shift in the financial landscape often leads to a redistribution of power between the exiting founder and the acquiring entity.
Retention Cost
Buyers view the rapid vesting of shares as a threat to post-merger stability because it removes the golden handcuffs that keep specific talent in place. To counter this, an acquirer may insist on new vesting terms or holdbacks that effectively replace the accelerated interest with a new set of service requirements. This negotiation adds a layer of friction to the closing process.
