Change of control is a defined shift in who owns or controls a company — typically via merger, acquisition, asset sale, or transfer of a majority of voting stock.

How it works

Legal agreements define change of control precisely — not every small investment qualifies. Common triggers:

• Sale of all or substantially all assets
• Merger where pre-transaction shareholders own less than half of the surviving entity
• Transfer of majority voting power to a new party

Effects cascade:

• Investor protective provisions — preferred shareholders may have consent or veto rights
• Employee equity — single-trigger or double-trigger acceleration of option vesting
• Debt covenants — lenders may demand repayment or renegotiation
• Customer and partner contracts — assignment clauses may require notice or consent

Founders planning buyout or strategic sales run change-of-control analysis in week one of banker engagement.

Acquirers diligence change-of-control consents early — discovering a blocking preferred holder late in process can collapse timelines or force renegotiated price and structure to obtain waivers.

Why it matters

• Founders: Negotiate acceleration and retention pools before LOI — post-signing leverage drops. Map which investors can block or slow deals.
• Investors: Consent rights protect against fire sales below preference stacks; they also add process time acquirers must respect.

Common mistake

Assuming all employees get full vesting acceleration on any acquisition. Double-trigger acceleration requires both change of control and qualifying termination — read plan documents.
