What is a change of control?
A change of control is a contractually defined event in which the ownership or governance of a company shifts hands — most commonly through a sale of the business, a merger, the acquisition of a majority of voting stock, or a turnover of the board. It is one of the most heavily negotiated definitions in any credit agreement, commercial contract, or executive arrangement.
The term itself does nothing; it is a trigger. A change of control matters because dozens of other clauses are written to fire upon it — lender consent rights, debt acceleration, contract termination, vesting acceleration, and severance. Whether a given transaction counts as a change of control is therefore decided by the precise wording of each definition, which can vary contract to contract within the same company.
Because so much hangs on it, the definition is rarely left generic. It usually names specific thresholds — for example, any person or group acquiring more than 50% of voting power, or a sale of all or substantially all assets — so the parties know exactly when the consequences attach.
What a change of control typically triggers
The same event can set off several independent rights at once. The most common are:
- Lender consent or repayment. Credit agreements almost always treat a change of control as a mandatory prepayment event or a default, letting lenders demand repayment or renegotiate.
- Contract termination or consent. Key customer, supplier, license, and lease agreements often let the counterparty terminate or require its consent if the company changes hands.
- Executive payouts. Employment agreements and equity plans frequently carry change-of-control provisions — accelerated vesting, golden parachutes, or single- versus double-trigger severance.
- Regulatory and antitrust filings. A control shift can require notifications, licenses, or merger clearance before it can legally close.
In diligence, mapping every change-of-control clause across the contract base is a core workstream — an overlooked consent right can stall or reprice a deal.
Single trigger versus double trigger
In executive compensation and equity, the distinction between a single and a double trigger is critical. A single-trigger provision accelerates vesting or pays severance the moment a change of control closes, regardless of what happens to the employee. A double-trigger provision requires two events: the change of control and a qualifying termination — typically being let go without cause or resigning for good reason within a defined window after the deal.
Buyers strongly prefer double triggers because they keep key talent incentivized to stay through the transition rather than walking away fully vested on day one. Single triggers are seen as buyer-unfriendly and are a frequent point of renegotiation before a deal signs.
