An acquisition can create merger-control risk before closing. The main concern is that buyer and target begin acting as one business while clearance is still pending.

Gun-jumping covers premature implementation or influence before the required clearance. The exchange of information also needs a clear purpose and access control.

This article distinguishes the issue from the broader approval review and from contractual closing conditions.

Gun-jumping in an acquisition: merger-control restrictions before closing

Is the pre-closing information exchange between buyer and target restricted?

Until closing, the target generally remains independent. Review the purpose, scope, recipients and safeguards for each exchange.

All paths at a glance

Overview of all answers.

01

The exchange requires purpose and access controls.

Define which information is necessary for the review. Current prices, customer-level data, bids and strategic plans should not circulate without safeguards. Use a clean team, maintain an access record and delete information when the transaction purpose ends.

02

Document why the information is necessary and keep operational control separate.

Record the transaction purpose and avoid operational instructions, joint pricing or buyer control of daily management before closing. Reassess the categories if the transaction scope changes.

Why the standstill applies before clearance

Merger control must be effective before the transaction is implemented. Signing and closing are therefore separate. Filing does not itself equal clearance.

Before closing, the target generally remains independent. Side letters and practical instructions must not transfer control early.

Permitted and sensitive information in the data room

Due diligence needs information, but current prices, individual bids and customer-level data create different risks from historical or aggregated material. The assessment depends on the market and the recipients.

A clean team can limit access. It does not help if the information is later used by sales, procurement or pricing teams.

Draft interim covenants without premature control

Interim covenants protect value between signing and closing. They must not make the buyer the operator of the target. Consent rights should focus on exceptional actions and remain proportionate.

Each consent right should have a documented rationale. The article on interim covenants explains the contract mechanics.

Document the process in the SPA and closing file

The SPA should address filing, standstill, responsibility and cooperation. Add a short protocol for clean-team access and authority communications.

A review should show who received which information and when. This improves traceability without replacing legal advice.

Do not operate jointly before closing: Even well-intentioned coordination can create risk. Review the data room and interim covenants before sensitive information is exchanged.
