Between signing and closing, the buyer and the target are still separate companies. Merger control rules, including the waiting period for notifiable deals under US merger review and the standstill obligation under EU merger rules, bar implementing a deal before clearance, and competition law requires the parties to keep competing independently until closing. Acting as one business too early is often called gun-jumping.
Sharing competitively sensitive information, such as current pricing, customer terms or pipeline plans, can be part of that risk. Yet the buyer still needs to plan an integration, and planning needs information.
How clean teams help
A common answer is a clean team: a small, defined group, often outside advisers or employees without day-to-day commercial roles, who may see sensitive information under agreed rules. They prepare analysis for integration planning, and what they pass on is aggregated or cleared by counsel.
- Membership is named and limited, and agreed with antitrust counsel.
- Access is granted for a purpose, and ends when that purpose does.
- What leaves the clean team is controlled.
Where separation breaks down
- Access granted for diligence is never revoked, so former clean-team members keep it after their role ends.
- Data starts moving to the buyer’s systems before closing because a project plan says so.
- Rules live in a memo, and nothing stops a well-meant mistake on a busy day.
Enforce the line in the system
Policies matter, but the safest separation is one the tools enforce. Before closing, the system that moves data should refuse to move it to the buyer. Clean-team access should end on its own when the deal closes, and each ending should be recorded. And the decision to cross the line should require a signature from antitrust counsel.
