vesting acceleration

Trigger Specification

Acceleration terms fall into single-trigger structures that fire immediately upon a change of control, or double-trigger structures requiring both an acquisition and an executive termination. Single-trigger terms provide immediate equity liquidity to founders during an enterprise buyout, regardless of post-acquisition employment status. Double-trigger terms protect executives against termination by an acquiring management team while ensuring ongoing operational continuity for the buyer.

Ownership Compression

When an acceleration clause activates, the enterprise compresses years of remaining service vesting into an instantaneous share conversion event. An executive with two years remaining on a four-year vesting schedule receives immediate ownership of their entire remaining equity tranche. This sudden conversion increases the recipient fully diluted share count and absolute payout allocation at transaction close.

Enterprise Vulnerability

Granting unconditional acceleration provisions to non-essential personnel can jeopardize prospective merger and acquisition transactions. Acquirers frequently reduce purchase prices or refuse to close acquisitions if critical technical talent can achieve full equity liquidity without ongoing retention obligations. Vesting acceleration requires precise contractual tailoring to balance individual financial security against enterprise transaction viability.
