A reported transaction can involve multiple filings, and the adjusted denominator removes matters for which the agencies could not issue a Second Request.","enforcement":"Second Requests and public enforcement actions are different stages with different timing rules. Their counts must not be treated as a finding that every reviewed or reported transaction was anticompetitive.","earlyTermination":"Early termination statistics reflect requests and agency action under the rules operating in each fiscal year. Policy and publication changes make this series unsuitable as a standalone measure of enforcement intensity.","industry":"The FY2023 and FY2024 acquired-entity tables classify adjusted HSR transactions by 3-digit NAICS. They describe the federal review pipeline, not industry-wide merger rates, market definitions, competitive harm, or agency performance. Published row shares are independently rounded to one decimal place and therefore sum to 100.3% and 101.5%, respectively, while each official table total remains 100.0%.","industryComparison":"Release-to-release sector shifts aggregate each edition's exact published rows inside stable broad NAICS sectors. They are descriptive changes in the federal review pipeline, not merger rates, market-power measures, or causal estimates. Industry codes and labels that enter, exit, or change between tables remain explicit rather than being silently crosswalked.","intraIndustry":"An intra-industry transaction means the acquiring and acquired persons both reported revenue in the same 3-digit NAICS code. It does not establish a horizontal overlap, relevant antitrust market, or competitive effect."},"summary":{"recordCount":137,"latestFiscalYear":2025,"latestTransactionsReported":2006,"latestSecondRequests":41,"latestSecondRequestRatePercent":2.1,"latestOverOneBillionPercent":31.8,"latestEnforcementActions":18},"rows":[{"fiscalYear":2025,"rangeId":"100m-150m","label":"$100M-$150M","lowerBoundMillions":100,"upperBoundMillions":150,"transactionCount":61,"transactionPercent":3.1,"clearanceFtc":6,"clearanceDoj":1,"clearanceTotal":7,"clearanceRatePercent":11.5,"secondRequestsFtc":0,"secondRequestsDoj":0,"secondRequestsTotal":0,"secondRequestRatePercent":0,"sourceId":"ftc-doj-hsr-report-2025","sourceProfileHref":"/sources/ftc-doj-hsr-report-2025","observatoryHref":"/mergers/2025#merger-year-size"},{"fiscalYear":2025,"rangeId":"150m-200m","label":"$150M-$200M","lowerBoundMillions":150,"upperBoundMillions":200,"transactionCount":286,"transactionPercent":14.7,"clearanceFtc":6,"clearanceDoj":7,"clearanceTotal":13,"clearanceRatePercent":4.5,"secondRequestsFtc":1,"secondRequestsDoj":3,"secondRequestsTotal":4,"secondRequestRatePercent":1.4,"sourceId":"ftc-doj-hsr-report-2025","sourceProfileHref":"/sources/ftc-doj-hsr-report-2025","observatoryHref":"/mergers/2025#merger-year-size"},{"fiscalYear":2025,"rangeId":"200m-300m","label":"$200M-$300M","lowerBoundMillions":200,"upperBoundMillions":300,"transactionCount":195,"transactionPercent":10,"clearanceFtc":6,"clearanceDoj":1,"clearanceTotal":7,"clearanceRatePercent":3.6,"secondRequestsFtc":0,"secondRequestsDoj":0,"secondRequestsTotal":0,"secondRequestRatePercent":0,"sourceId":"ftc-doj-hsr-report-2025","sourceProfileHref":"/sources/ftc-doj-hsr-report-2025","observatoryHref":"/mergers/2025#merger-year-size"},{"fiscalYear":2025,"rangeId":"300m-500m","label":"$300M-$500M","lowerBoundMillions":300,"upperBoundMillions":500,"transactionCount":236,"transactionPercent":12.1,"clearanceFtc":12,"clearanceDoj":12,"clearanceTotal":24,"clearanceRatePercent":10.2,"secondRequestsFtc":3,"secondRequestsDoj":2,"secondRequestsTotal":5,"secondRequestRatePercent":2.1,"sourceId":"ftc-doj-hsr-report-2025","sourceProfileHref":"/sources/ftc-doj-hsr-report-2025","observatoryHref":"/mergers/2025#merger-year-size"},{"fiscalYear":2025,"rangeId":"500m-1b","label":"$500M-$1B","lowerBoundMillions":500,"upperBoundMillions":1000,"transactionCount":548,"transactionPercent":28.2,"clearanceFtc":19,"clearanceDoj":24,"clearanceTotal":43,"clearanceRatePercent":7.8,"secondRequestsFtc":8,"secondRequestsDoj":4,"secondRequestsTotal":12,"secondRequestRatePercent":2.2,"sourceId":"ftc-doj-hsr-report-2025","sourceProfileHref":"/sources/ftc-doj-hsr-report-2025","observatoryHref":"/mergers/2025#merger-year-size"},{"fiscalYear":2025,"rangeId":"1b-10b","label":"$1B-$10B","lowerBoundMillions":1000,"upperBoundMillions":10000,"transactionCount":599,"transactionPercent":30.8,"clearanceFtc":41,"clearanceDoj":44,"clearanceTotal":85,"clearanceRatePercent":14.2,"secondRequestsFtc":6,"secondRequestsDoj":10,"secondRequestsTotal":16,"secondRequestRatePercent":2.7,"sourceId":"ftc-doj-hsr-report-2025","sourceProfileHref":"/sources/ftc-doj-hsr-report-2025","observatoryHref":"/mergers/2025#merger-year-size"},{"fiscalYear":2025,"rangeId":"over-10b","label":"Over $10B","lowerBoundMillions":10000,"upperBoundMillions":null,"transactionCount":19,"transactionPercent":1,"clearanceFtc":7,"clearanceDoj":3,"clearanceTotal":10,"clearanceRatePercent":52.6,"secondRequestsFtc":2,"secondRequestsDoj":2,"secondRequestsTotal":4,"secondRequestRatePercent":21.1,"sourceId":"ftc-doj-hsr-report-2025","sourceProfileHref":"/sources/ftc-doj-hsr-report-2025","observatoryHref":"/mergers/2025#merger-year-size"}]}
