Research memo / source-backed packet

Federal merger activity competition briefing

Frame a reproducible research agenda while keeping metrics, periods, universes, and inference limits separate. This packet keeps 2 latest-to-prior observations across 1 evidence system separate and does not rank or combine them.

Federal merger activity / Transaction volume

Hart-Scott-Rodino program

-25
FY20242,031
1 year
FY20252,006

The latest reported transaction volume is lower than the prior fiscal year. This is a program-activity comparison, not a finding about merger harm or enforcement effectiveness.

Research questionHow did filing mix, transaction size, thresholds, exemptions, and macroeconomic conditions change alongside notification volume?

Federal merger activity / Review rate

Hart-Scott-Rodino program

-0.90 pp
FY20243.0%
1 year
FY20252.1%

The latest reported review rate is lower than the prior fiscal year. This is a program-activity comparison, not a finding about merger harm or enforcement effectiveness.

Research questionHow did transaction mix, clearance, adjusted denominators, and agency review practice change alongside the observed rate?
Interpretation boundary

Every signal compares declared observed anchors inside the same series or cross-section. Missing years are not interpolated, intervals are not annualized, and market, industry, geographic, business-flow, and merger measures keep separate units, universes, period bases, and legal meanings. Antitrust Radar does not combine them into a composite competition score.

Publication standard

A briefing is a research handoff, not a finding of liability.

Every exported packet carries the observed comparison, source register, bounded interpretation, next research question, and the global no-composite-score rule.

  1. 01
    State what changed

    Report the exact prior and latest anchors with their period basis and interval.

  2. 02
    Keep systems separate

    Do not compare the magnitude of unlike HHI, share, business-flow, transaction, and review-rate changes.

  3. 03
    Open the investigation

    Route each signal into its underlying profile, explorer, source records, and research question.

Research handoffs

Continue in the underlying evidence system.

The studio packages current observations; profiles, explorers, reports, and public data remain the authoritative analytical surfaces.
