Deemed assignment is when a deal is treated as transferring a contract even though no document expressly assigns it, which can trigger the anti assignment and change of control terms a buyer must clear before relying on that contract.
What is deemed assignment? Deemed assignment is when a transaction is treated as an assignment of a contract even though no instrument explicitly transfers it. Many contracts say that a merger, a change of control, or a transfer by operation of law shall be deemed an assignment. When that language is present, the deal itself triggers the assignment provisions, including any clause that requires the other party consent or that lets them terminate. The transfer is not written down, it is inferred from what the deal does.
A buyer prices a deal on the assumption that the target contracts come with it. Deemed assignment is where that assumption can break. A software license the target relies on may contain anti assignment language that catches the deal even though no one signed an assignment. If the clause requires consent, the buyer needs that consent or the license is at risk. If it allows termination or repricing, the publisher gains leverage exactly when the buyer is least able to resist. The exposure is usually latent, sitting unread in contracts until the structure brings it to life.
This is why deemed assignment cannot be separated from deal structure. An asset purchase generally assigns contracts directly, so consent is squarely in play. A stock purchase keeps the same legal entity, which can avoid a plain assignment but still triggers change of control terms that treat the share transfer as a deemed assignment. A merger may be a deemed assignment by operation of law, and the outcome can vary by jurisdiction and by the precise wording of the clause. Reading the contracts against the chosen structure is what tells a buyer which clauses actually bite.
The contracts most likely to carry these terms are the ones that matter most. Enterprise agreements from Oracle, SAP, Microsoft and IBM, and increasingly Broadcom following VMware, often combine anti assignment, change of control, and audit rights in a way that lets a publisher convert a structural event into a commercial negotiation. A buyer who maps deemed assignment risk before signing can plan consents, time approaches to publishers, and avoid handing over leverage. This is commercial and licensing advisory, not legal advice, and the reading of any specific clause should sit with the buyer own counsel.
| Structure | Effect on contracts | Buyer action |
|---|---|---|
| Asset purchase | Direct assignment of contracts | Secure consents on key licenses |
| Stock purchase | Same entity, change of control may apply | Check change of control clauses |
| Merger | May be deemed assignment by law | Confirm by contract and jurisdiction |
| Carve out | New entity needs fresh rights | Plan relicensing before separation |
