The change-of-control provisions in an acquisition agreement get reviewed. The change-of-control provisions in the target company's customer contracts, vendor agreements, SaaS subscriptions, regulatory licenses, and credit facilities sometimes do not, at least not with the same systematic attention. That asymmetry is where post-closing surprises come from.
A change-of-control trigger in a third-party agreement is a contractual right that activates when the ownership or control of one party changes. Depending on how the provision is drafted, it may give the counterparty the right to terminate the contract, require consent before the transaction can close, accelerate payment obligations, or modify the commercial terms going forward. In aggregate across a target company's contract portfolio, these provisions can represent a meaningful portion of the value the buyer believed it was acquiring.
Where Change-of-Control Provisions Actually Live
The acquisition agreement itself will contain its own change-of-control definition, typically used in the context of the seller's representations about material contracts and the covenants around third-party consents. What that agreement does not contain is a complete review of every contract in the target's business that independently defines change of control and attaches consequences to it.
The categories that most frequently contain consequential change-of-control language include the following.
Customer contracts, particularly enterprise software and services agreements, often include termination rights triggered by acquisition. A customer who entered a long-term contract with a specific counterparty may have negotiated the right to exit if that counterparty is acquired by a competitor, a strategic buyer in a related market, or simply any third party not pre-approved by the customer. The right is usually notification-based, requiring the acquired company to notify the customer within a defined window after closing and the customer to exercise within a further defined window or lose the right.
SaaS subscription agreements and platform licenses increasingly include anti-assignment provisions that function as change-of-control triggers even when they do not use the term directly. A standard "no assignment without consent" clause in an enterprise SaaS contract, combined with a definition of assignment that includes any change in the effective control of the contracting party, gives the SaaS vendor consent rights over the M&A transaction itself. In a software-heavy target, this can apply to dozens of agreements simultaneously.
Regulatory licenses in industries requiring government authorization frequently include change-of-control review or approval requirements. Operating licenses, spectrum licenses, financial services registrations, and professional certifications may require the acquiring party to seek regulatory approval or notification before or after the change of control. Failure to comply can result in license suspension or loss, which is not a post-closing indemnification problem, it is an operational problem that affects the business the buyer just acquired.
Credit facilities and debt covenants commonly include change-of-control definitions that trigger acceleration, mandatory prepayment, or an event of default. Many middle-market credit agreements include a provision that a change of beneficial ownership above a specified threshold (often 35% to 50%) constitutes a default. If the acquisition leaves existing debt in place rather than paying it off at closing, the change-of-control provision in the credit agreement will need to be addressed through a waiver, amendment, or refinancing before or concurrently with closing.
How the Definition of Change of Control Varies
One of the less obvious complications is that change-of-control definitions vary significantly across the agreements in a single target's contract portfolio. Some definitions trigger on any change in the party with majority ownership. Others require a change in both ownership and control, defined as the ability to direct management decisions. Still others define change of control to include only acquisitions by direct competitors, or to exclude acquisitions by financial buyers.
This definitional variation means that a systematic diligence review cannot rely on a single pass for the phrase "change of control" across all contracts. The review must identify the definition actually used in each contract and assess whether the proposed acquisition structure satisfies that definition. A merger where the target's existing shareholders retain a minority stake after closing may or may not constitute a change of control depending on the specific language in each agreement.
Asset purchase structures introduce a related complication: assignment-based change-of-control equivalents. When a buyer acquires the business through an asset purchase rather than a stock acquisition, the target entity does not change hands, but the contracts, licenses, and agreements must be assigned to the buyer. Most commercial contracts require consent for assignment. A counterparty that would have had limited rights under a standard change-of-control clause in a stock deal may have full consent rights in an asset deal because the mechanism triggering review is assignment rather than change of control.
The Consent Process Before Closing
Once material change-of-control triggers have been identified, the purchase agreement must address how they are handled. The standard approach is a representation by the seller that no material contracts require third-party consent as a result of the transaction, with a schedule of exceptions listing those that do. This representation is only as good as the diligence that produced the schedule.
Where consents are required, the agreement typically includes a pre-closing covenant requiring the seller to use commercially reasonable efforts, or a stronger standard, to obtain them before closing. The critical question is what happens if a material consent is not obtained by closing: does the buyer have the right to decline to close, or does the transaction proceed with an indemnification backstop for the exposure?
For mission-critical contracts, particularly anchor customer agreements or operating licenses, allowing the transaction to close without the required consent carries real operational risk. The counterparty's consent right does not disappear because the parties chose to proceed; it remains exercisable after closing. A buyer who closes without a key customer's consent and then receives a termination notice from that customer has acquired a business with a known breach already in progress.
What Thorough Review Looks Like
A first-pass review of change-of-control exposure starts with the contract schedule in the disclosure materials and maps each material contract against three questions: does it contain a change-of-control definition or an anti-assignment provision? does the proposed deal structure satisfy that definition? and if consent is required, what is the consequence of not obtaining it?
This is not a review that can be completed by reading only the acquisition agreement. It requires access to the underlying contracts, which means it belongs in the diligence phase, not the contract review phase. The representation about required consents is the conclusion of that review process; it is not a substitute for conducting it.
We recognize this is broader than what many practitioners classify as contract review. But change-of-control exposure often determines more of the transaction's post-closing value than the indemnification structure does, and it is identified in a phase that frequently receives less systematic attention. The gap between what the purchase agreement says about consents and what the target's actual contract portfolio requires is where the practical exposure lives.
