Reportability and exemptions
Each transaction is analyzed against the size-of-transaction and size-of-person thresholds, and all applicable exemptions are checked — no filing is released without a documented reportability determination.
The most rigorous HSR filing a deal team can submit.
HSR Premerger Filing Engine delivers a documentation-complete, attorney-certified Hart-Scott-Rodino premerger notification — the complete Form, certification, 4(c)/4(d) document set, NAICS/NAPCS revenue-overlap analysis, and supporting exhibits — assembled by an internal AI production engine and signed off by a licensed antitrust attorney, at a fixed per-filing fee.

Why filings fail
A single defect can restart the waiting period and threaten your closing date.
Every U.S. merger or acquisition above the Hart-Scott-Rodino size-of-transaction threshold ($133.9M for 2026) must file a premerger notification with the FTC and DOJ and observe a statutory waiting period before closing. A defective filing is 'bounced' (rejected) by the Premerger Notification Office, restarting the clock and threatening the closing date.
Most deal teams send this work to BigLaw at full hourly rates — $30K–$100K+ for straightforward filings — or try to manage it in-house under deadline pressure. The form is complex, the 4(c)/4(d) document identification is judgment-intensive, and the rules are in active flux (the 2024 expanded form was vacated in February 2026, and a new form is under RFI).
HSR Premerger Filing Engine exists to close that gap with a single, exhaustive standard applied identically to every filing.

The benchmark
Measured against the letter of the HSR Act and FTC rules — subsection by subsection.
We do not summarize the law and hope. Every filing is scored against a versioned rule pack tied to the exact text of 15 U.S.C. §18a and the FTC's implementing regulations. These are the provisions each filing is held to.
Complete Form and certification
The HSR Form is drafted field-by-field from validated deal data, and an attorney certification is executed — every required item present, or the filing does not release.
4(c)/4(d) document set
All responsive deal-evaluation studies, analyses, and confidential information memoranda are identified, privilege-screened, and included — established by search, not assumption.
Revenue-overlap analysis
NAICS/NAPCS revenue data for both parties is compiled and any horizontal or vertical overlaps are documented — no overlap is left unaddressed.
Prior acquisitions detail
All prior acquisitions by the acquiring person within the last five years are listed, with entity names, jurisdictions, and dates — verified against corporate records.
Waiting period and timing
The initial 30-day waiting period is calculated deterministically from the filing date, and the filing is scheduled to ensure the period expires before the planned closing date.
How a filing is built
Intake to attorney release, with deterministic gates the AI cannot overrule.
AI extracts and drafts. Deterministic rules — running as code, outside the model — decide what is complete. A licensed antitrust attorney signs every release. That order is never reversed.

Why HSR Premerger Filing Engine
Built to be the most thorough option a deal team has.
Documentation-complete, by design
The deliverable is completeness itself — every statutory element and document accounted for or explicitly exception-coded. Nothing is left implicit.
Deterministic, not vibes
The gates that decide completeness are code, not a model's opinion. A drafting error cannot slip past a statutory requirement.
In its lane, on purpose
We prepare documentation and run searches as your clerical agent. We never provide legal advice or make substantive legal judgments without attorney review.
Engagement
Flat fee, per released filing. No hourly billing, ever.
Simple, predictable, and aligned with a documentation standard — not a cut of any deal value.
- A free Filing Readiness Scan before you commit — see exactly what is missing.
- One flat fee per released filing, tiered by complexity; disclosed pass-through government filing fees.
- Optional fixed-fee attorney review for complex transactions with horizontal/vertical overlaps.
- Optional Expedited Review Add-on for filings needed in under 5 business days.
FAQ
Questions, answered precisely.
Is HSR Premerger Filing Engine a law firm?
No. HSR Premerger Filing Engine, a service of Your Deputy, Obuke LLC, provides documentation-completeness services. It is not a law firm, does not provide legal advice, and does not represent you in any legal matter. Attorney review is available and recommended for complex transactions.
Do you submit the filing to the FTC/DOJ?
No. The filing is delivered to you ready for submission. You or your counsel submit it to the Premerger Notification Office. We remain your clerical agent throughout.
What makes a filing 'complete'?
Completeness is defined by the HSR Act and FTC rules: the Form is fully and accurately filled, the 4(c)/4(d) document set is complete and privilege-screened, the revenue-overlap analysis is documented, prior acquisitions are listed, and the waiting period is calculated. Deterministic gates enforce each one before release.
How fast is it?
The standard SLA is five business days from complete intake to an attorney-released filing. The free Filing Readiness Scan is returned much sooner and tells you exactly what is still needed.
How are you priced?
A flat fee per released filing, plus disclosed pass-through government filing fees. No hourly billing and no percentage of any deal value.
