# Analyzing Anti Trust Risk Evaluates competition law exposure with market definition, HHI analysis, and remedy estimation for proposed transactions. ## When To Use - Assessing merger or acquisition clearance risk before signing or announcement - Preparing or reviewing HSR (Hart-Scott-Rodino) filing strategy and timing - Evaluating whether a bolt-on acquisition triggers size-of-transaction or size-of-person thresholds [VERIFY: current HSR thresholds adjust annually] - Analyzing market concentration impact for board presentations or investment committee memos - Screening a target portfolio for divestitures likely required as merger remedies - Supporting second-request preparation or response strategy ## Inputs To Gather - **Transaction details**: deal structure (stock vs. asset), purchase price, combined entity post-close - **Party financials**: total assets and annual net sales for both buyer and target (for HSR threshold analysis) - **Relevant product/service markets**: descriptions of overlapping business lines, substitutes, and complements - **Geographic scope**: national, regional, or local market definitions as applicable - **Market share data**: revenue or unit-based shares for each party and top competitors in each relevant market - **Customer and supplier concentration**: key accounts, switching costs, and contractual lock-in periods - **Prior agency interactions**: any previous DOJ/FTC investigations, consent decrees, or clearance history involving either party - **Comparable transactions**: recent deals in the same sector and their regulatory outcomes ## Workflow 1. **Determine HSR applicability** - Calculate size-of-transaction and size-of-person tests against current thresholds [VERIFY: thresholds update each February] - Identify whether any exemptions apply (e.g., acquisitions of non-voting securities, certain real estate transactions) - Flag if foreign antitrust filings are also required (EU merger regulation, CMA, SAMR, etc.) [VERIFY: jurisdiction-specific thresholds] 2. **Define relevant markets** - Identify candidate product markets using the hypothetical monopolist (SSNIP) framework - Delineate geographic markets based on customer purchasing patterns, transportation costs, and regulatory boundaries - Document alternative reasonable market definitions and note how each affects concentration metrics 3. **Calculate market concentration (HHI)** - Compute pre-merger HHI for each relevant market - Compute post-merger HHI and the delta (change in HHI) - Apply DOJ/FTC Horizontal Merger Guidelines thresholds: - Post-merger HHI < 1,500: unconcentrated — unlikely to raise concerns - Post-merger HHI 1,500–2,500: moderately concentrated — delta > 100 warrants scrutiny - Post-merger HHI > 2,500: highly concentrated — delta > 200 presumptively raises concerns [VERIFY: confirm current Guidelines thresholds] 4. **Assess competitive effects** - **Unilateral effects**: evaluate whether the merged firm could profitably raise prices due to elimination of close substitutes; assess diversion ratios where data permits - **Coordinated effects**: evaluate whether the merger increases likelihood of tacit coordination among remaining competitors (market transparency, product homogeneity, history of coordination) - **Vertical effects**: if the deal has a vertical dimension, assess foreclosure risk to rivals or customers - **Buyer power / countervailing factors**: consider whether large buyers or low barriers to entry offset concentration concerns 5. **Evaluate likely remedies and timing risk** - Identify product lines or geographies most likely to require divestiture - Estimate the value and operational feasibility of potential divestitures - Assess whether behavioral remedies (firewalls, licensing) might be accepted as alternatives - Project regulatory timeline: initial waiting period, likelihood of second request, estimated time to clearance or litigation 6. **Assign overall risk rating** - **Low**: unconcentrated markets, no significant overlap, clean filing expected - **Moderate**: moderately concentrated markets or delta in sensitive range; second request possible but clearance likely with limited remedies - **High**: highly concentrated markets with significant delta; second request expected; material divestitures or deal restructuring likely required - **Prohibitive**: agency challenge highly probable; litigation risk or deal abandonment should be modeled ## Output The deliverable should include: - **Executive summary**: one-paragraph risk assessment with overall rating (Low / Moderate / High / Prohibitive) - **HSR filing analysis**: threshold calculations, filing fee estimate, and timing implications - **Market-by-market concentration table**: relevant market, parties' shares, pre/post HHI, delta, and risk flag - **Competitive effects narrative**: concise analysis of unilateral, coordinated, and vertical theories of harm - **Remedy scenario matrix**: potential divestitures or conditions mapped to affected markets, with estimated impact on deal value - **Timeline and process overview**: expected regulatory milestones from filing through clearance - **Key assumptions and data gaps**: explicit list of inputs assumed or unavailable, each flagged with [VERIFY] where appropriate ## Quality Checks - HHI calculations verified against stated market shares (shares should sum to approximately 100%) - HSR threshold figures cross-referenced against the most recent annual adjustment [VERIFY] - Market definitions are internally consistent — product and geographic boundaries align with the data used for share calculations - Risk rating is consistent with the quantitative concentration analysis and qualitative competitive effects discussion - Remedy estimates are grounded in precedent from comparable transactions, not speculative - All jurisdiction-dependent figures, thresholds, and filing requirements are marked [VERIFY] - Analysis distinguishes between confirmed data and estimates/assumptions throughout
