What Is a Second Request?

The second request definition comes straight from the HSR Act. Its formal name is a Request for Additional Information and Documentary Material, and it is the tool federal antitrust agencies use when an initial merger review raises competition concerns they cannot resolve on the first filing alone.

Only a small share of reportable deals receive one. For the deals that do, the second request meaning is practical as much as legal: the merging parties must gather, review, and produce a large volume of documents and data before their transaction can close. The HSR second request meaning is the same whichever agency issues it, since every Second Request arises under the HSR Act.

That is why the term appears in an eDiscovery glossary. In antitrust practice, a Second Request is a stage of merger review. Inside a legal team, it is a high-volume document production run on a regulator's clock. The two roles run on the same deadline, which is why deal counsel and eDiscovery teams plan the response together from the start.

How a Second Request Works

The agencies must issue a Second Request before the initial HSR waiting period expires. Once it arrives, the clock stops. The waiting period does not resume until both parties substantially comply with the request. Issuing one is at the agency's discretion, and it signals that the deal has moved from routine screening into an in-depth investigation.

The request itself is broad. Typical specifications demand internal emails and chats, strategic plans, market analyses, and transactional data from a defined set of custodians, often reaching back several years. Modern requests reach collaboration platforms and shared drives as well, not just email. The parties can negotiate scope, custodian counts, and timing with the agency, but the core obligation remains.

After substantial compliance, a second waiting period begins, generally 30 days, or 10 days for cash tender offers. The agency then clears the deal, negotiates remedies, or moves to block it. In practice, parties often enter timing agreements that give the agency additional review time in exchange for a more predictable schedule.

Responding to a Second Request

Meeting the deadline without missing responsive data depends on a few core practices:

• Issue a legal hold as soon as a Second Request looks likely.
• Map custodians and data sources across email, chat, and shared systems.
• Preserve electronically stored information before routine deletion can run.
• Cull the dataset with analytics before costly document review begins.
• Produce documents and metadata in the format the agency specifies.

Agencies judge the response by its defensibility as well as its speed, so a documented, repeatable process matters as much as the deadline itself.

Why a Second Request Matters

A second request antitrust review compresses years of data into a production measured in weeks and months, and the deal cannot close until it is done. Every day of delay in compliance is a day added to the transaction timeline, which puts eDiscovery speed directly on the critical path of the deal. Review at that volume is also expensive, so early culling decisions carry real budget consequences.

The stakes are regulatory as well. Certifying substantial compliance while responsive material is missing invites agency challenges, and closing before the process ends violates the HSR Act, which carries daily civil penalties. Documenting search terms, review protocols, and privilege calls as they are made keeps the response defensible if the agency questions it later.

Frequently Asked Questions

What does a Second Request mean in antitrust?

It means the FTC or DOJ needs more information before deciding whether a merger raises competition concerns. The agency issues a Request for Additional Information and Documentary Material, and the deal cannot close until the parties substantially comply and a further waiting period runs.

How common are Second Requests?

Only a small fraction of reportable transactions receive one. Most HSR filings clear during the initial waiting period without any additional demand for information.

What is substantial compliance with a Second Request?

Substantial compliance means the parties have produced the documents and data the request requires, completely enough to restart the waiting period. Certifying compliance while responsive material is missing can draw an agency challenge.

Why does a Second Request involve eDiscovery?

A Second Request routinely demands years of emails, chats, and files from many custodians on a strict deadline. Collecting, reviewing, and producing that volume defensibly is an eDiscovery project by any measure.
