FTC Announces Increased 2026 HSR Reporting Thresholds and Filing Fees
January 15, 2026
The Federal Trade Commission (FTC) has announced increases to the reporting thresholds and exemptions that dictate whether companies must notify antitrust authorities about a transaction. To keep pace with inflation, the Hart-Scott-Rodino Act of 1976 (HSR Act) requires the FTC to adjust these thresholds annually based on changes in the gross national product (GNP). The revised thresholds will apply to all transactions that close on or after the effective date, which is 30 days after the Federal Register publishes the FTC’s announcement (likely within the next week).
In addition, the FTC announced updated filing fees, which are also adjusted annually based on changes in the GNP, as well as the consumer price index pursuant to the Consolidated Appropriations Act. Filing fees are determined by the value of the transaction at the time of filing.
Under the New Thresholds:
The minimum size-of-transaction threshold is US$133.9 million (up from US$126.4 million). Acquisitions below this threshold are not reportable.
Transactions exceeding the size-of-transaction threshold—but less than US$535.5 million—are reportable if the ultimate parent entity of one party has sales or assets of at leastUS$267.8 million, and the ultimate parent entity of the other party has sales or assets of at least US$26.8 million (the “size-of-person” test).
Transactions valued at more than US$535.5 million are reportable regardless of the size-of-person test.
Both filing fees—and the size-of-transaction thresholds (on which the filing fee is based)—were altered. They are as follows:
| Filing Fee (US$) | Size of Transaction as Determined Under Section 7A(a)(2) of the HSR Act (US$) |
| $35,000 | Less than $189.6 million |
| $110,000 | Not less than $189.6 million, but less than $586.9 million |
| $275,000 | Not less than $586.9 million, but less than $1.174 billion |
| $440,000 | Not less than $1.174 billion, but less than $2.347 billion |
| $875,000 | Not less than $2.347 billion, but less than $5.869 billion |
| $2.460 million | $5.869 billion or more |
The notification threshold for 25% of the outstanding voting shares is US$2.678 billion; for 50% of the outstanding voting shares, it is US$126.4 million.
Even if a transaction is reportable based on the above thresholds, it may qualify for one of the HSR Act’s exemptions, some of which also contain updated financial thresholds. For example, a US person’s acquisition of a foreign issuer’s stock is exempt, unless the foreign issuer has either US assets or sales exceeding US$133.9 million. Elaborate rules govern deal valuation and exemptions under the HSR Act. Consult HSR counsel to determine whether a deal is reportable.
