Merger clearances (HSR)
Mergers and acquisitions the FTC and Justice Department cleared early under the Hart-Scott-Rodino Act, with the public companies among them. Granted requests only.
About this data
- What it is
- Companies planning a merger or acquisition above a size threshold must tell the FTC and the Justice Department first and wait 30 days before closing (the Hart-Scott-Rodino Act). The parties can ask for that wait to end early, and when the agencies agree, the FTC publishes an early termination notice. This feed lists those notices: the buyer, the target, the entities being acquired and the day early termination was granted. We match each name to a public company when it lines up.
- Who files it
- The FTC, which publishes a notice once it and the Department of Justice have granted the request.
- How current
- We check the FTC's list every day. A notice is published when early termination is granted, which is before the deal closes.
- Terms
- Hart-Scott-RodinoThe Hart-Scott-Rodino Act requires companies planning a merger or acquisition above a size threshold to tell the FTC and the Justice Department first and wait 30 days before closing, so the agencies can look for competition problems.Early terminationThe parties can ask for that waiting period to end sooner. When the agencies agree, the FTC publishes an early termination notice. It means the deal was cleared to close early, not that the agencies endorse it.Possible matchWe match each name to a public company automatically. A name that matches closely is shown as a company; a looser match is marked "possible match" because a similar name, a subsidiary or a differently spelled name can be matched wrongly. Most parties are private companies and funds and have no match.
- Worth knowing
- This is a partial list of deals, not every merger. Only requests that were granted appear: deals that waited out the full 30 days, deals whose request was refused and deals that were never reportable are not listed. The FTC granted no early terminations from February 2021 until the new HSR form took effect in February 2025, so there is nothing between those dates. A notice does not mean the agencies endorse a deal, and it does not say whether the deal closed. Most buyers and targets are private companies, funds or people. We match names to public companies automatically; a looser match is marked "possible match" because a similar name, a subsidiary or a differently spelled name can be matched wrongly.
This comes from the FTC's list of early-termination notices.
