## Summary

**Mandatory divestiture for mega‑mergers** is the central aim of this bill. It would add a new Section 7B to the Clayton Act to force or hold‑separate transactions worth at least $10 billion that close during a covered period from January 20, 2025 to January 19, 2029 and to expand post‑merger review of deals that slipped past enforcement. - Companies and acquirers: Companies that close transactions worth at least $10 billion during the covered period would face mandatory full divestiture if the deal predates the bill or strict hold‑separate rules while agencies review the deal, unless a court exempts the deal by showing narrow market tests such as an HHI below 1,800. - State attorneys general and courts: State attorneys general can intervene unconditionally in enforcement‑lapse challenges, and courts can appoint divestiture trustees and impose heavy civil penalties such as $100,000 per day or 5% of a transaction's value for knowing violations. - Consumers, workers, and competition: Federal agencies would be able to reopen reviews of closed deals to probe price increases, output or employment reductions, misrepresentations, improper political interference, or foreign influence, and structural remedies like divestiture are the presumptive way to restore competition.
