1. What Actually Drives the Cost of an Hsr Filing?
The government fee is only one part of the budget. HSR analysis, form preparation, deal documents, competition review, and agency contact create separate work. Costs rise if review expands.
Separate Government Fees from Professional Costs
- Government fee: Use the fee schedule in effect when the HSR waiting period begins.
- Attorney work: Budget for reportability analysis, filing preparation, document review, and agency contact.
- Other work: Add data vendors or economic experts when the investigation calls for them.
For filings under the 2026 fee schedule, fees range from $35,000 to $2.46 million by deal value. A Hart-Scott-Rodino filing review can connect the applicable tier with the deal budget.
Match Billing to the Scope
- Initial filing: Fixed or alternative fees may fit work that can be defined in advance.
- Expanded review: Hourly billing may apply when agency questions or document work broaden the assignment.
- Scope changes: Identify which events move work beyond the initial engagement.
More work can raise the budget as review grows.
2. Why Can a Second Request Change the Budget so Quickly?
A Second Request can turn a filing into a document, data, and competition investigation. Under 15 U.S.C. § 18a(e), the FTC or DOJ may require more information or documents. Scope can materially change workload and timing.
Identify the Main Cost Drivers
| Workstream | Cost Driver | Planning Question |
|---|---|---|
| Documents | Custodians and data volume | Where is responsive material stored? |
| Competition | Market and business data | What overlap is under review? |
| Experts | Economic issues | Is specialist analysis needed? |
| Agency response | Scope and timing | Which issues need early discussion? |
Cost comes from response work, not the label itself. Collection, production, privilege review, data analysis, and business input can add time and expense.
Address Scope before Rework Builds
- Custodians: Identify likely employees, files, and systems before collection grows.
- Data: Map email, messages, financial records, customer data, and deal files early.
- Agency discussions: Raise appropriate scope, burden, and production issues with agency staff.
FTC Second Requests invite modification discussions and provide an internal appeal process for certain unresolved disputes. In July 2026, DOJ also resumed targeted Second Request reviews using timing agreements that may prioritize selected information before full compliance. DOJ may then close its investigation, modify the request, or require full compliance.
3. How Can Deal Teams Control Document and Expert Costs?
Large productions cost more when collection starts without a clear map. Identify custodians, systems, date ranges, and competition issues before review scales up. Expert work should follow the questions under review.
Build Collection Around the Investigation
- Preservation: Preserve potentially responsive deal and competition records when applicable duties arise.
- Collection: Identify relevant systems and custodians before pulling broad data sets.
- Privilege: Build privilege review into the workflow rather than leaving it for the end.
An antitrust and competition law assessment can tie document work to the competitive issues driving review.
Use Experts for Defined Questions
- Competition: Decide whether market definition, entry, pricing, or effects require economic analysis.
- Data: Confirm usable business data before building an expert assignment.
- Extended review: Reassess expert needs if new economic issues emerge.
4. When Do Remedy Discussions Add Another Cost Layer?
A Second Request does not mean a remedy will follow. If an agency identifies competitive concerns, remedy talks may add valuation, separation, negotiation, and deal work.
Test Remedy Work against Deal Economics
- Divestiture: Assess assets, staff, contracts, systems, and separation work.
- Other obligations: Examine compliance or operating requirements if another form of relief is discussed.
- Deal value: Compare proposed relief with the transaction's commercial purpose.
Plan Divestiture Work When Relevant
- Buyer: A proposed divestiture may require analysis of a purchaser and its ability to operate the assets.
- Separation: Shared systems, contracts, personnel, or intellectual property can complicate implementation.
- Terms: Review regulatory obligations with closing conditions and risk allocation.
Remedy talks can affect the broader mergers and acquisitions structure if the assets expected to transfer may change.
5. How Can Parallel Merger Reviews Stay within Budget?

HSR is federal, but a deal may face separate state, foreign, or sector review. Shared factual work can reduce duplication without blending different legal standards.
Coordinate Facts without Combining Legal Tests
- Core facts: Keep transaction structure, ownership, and business descriptions consistent where facts match.
- Separate tests: Apply each jurisdiction's filing and substantive standards independently.
- Calendar: Track filings, information requests, waiting periods, and closing conditions together.
Watch for Signs Review May Expand
- Overlap: Examine meaningful product, service, customer, or geographic overlaps.
- Deal documents: Review how internal materials describe rivals, pricing, market position, and deal rationale.
- Data burden: Identify fragmented systems or large custodian groups that could complicate a response.
6. Frequently Asked Questions
Can an FTC Second Request be modified?
Potentially. FTC staff may discuss modifications that address burden while meeting investigative needs. The approach depends on the request and issues under review.
Does a Second Request mean the merger will be blocked?
No. It means the agency needs more information. Review may end without challenge, lead to remedy talks, or move toward litigation.
Does substantial compliance immediately allow closing?
Not necessarily. Substantial compliance starts the applicable additional waiting period, and the parties must account for that period and other closing restrictions.
Can one HSR budget include foreign merger filings?
Parallel reviews can share factual work and project management, but foreign regimes have separate tests, requirements, and schedules. Keep distinct regulatory workstreams.
7. Plan the Hsr Budget before Review Expands
A useful HSR budget separates the initial filing from work that may follow an extended investigation. SJKP's attorneys can assess filing duties, Second Request scope, data work, competition issues, remedies, and parallel reviews. Companies considering an HSR filing can contact SJKP before the transaction timetable tightens.
