The FTC Announces Increased HSR Thresholds for 2026

Brownstein Client Alert, Jan. 15, 2026

On Jan. 14, 2025, the Federal Trade Commission announced the 2026 adjusted thresholds under the Hart-Scott-Rodino Antitrust Improvements Act of 1976 (“HSR Act”). The HSR Act notification requirements apply to transactions that satisfy the specified “size of transaction” and “size of person” dollar thresholds. These dollar thresholds change from year to year, as the HSR Act requires an annual threshold adjustment based on changes in the U.S. gross national product for each fiscal year. The newly announced 2026 thresholds are expected to become effective 30 days following publication in the Federal Register and will be applicable to all transactions that close on or after such effective date until recalculated in early 2027.

The key HSR Act threshold adjustments are summarized in the following chart:

Test 2025 Threshold 2026 Adjusted Threshold
Size of Transaction $126.4 million $133.9 million
Size of Person (lower) $25.3 million $26.8 million
Size of Person (higher) $252.9 million $267.8 million
Size of Transaction Where Size of Person Is Not Relevant $505.8 million $535.5 million

The “size of transaction” threshold is determined based on the value of voting securities, non-corporate interests and/or assets held as a result of the transaction. Under the new 2026 thresholds, there will be no HSR Act notification requirements for transactions valued at less than $133.9 million.

For deals with an acquisition price of $133.9 million or more but less than $535.5 million, the parties will need to consider the “size of person” test. Under the “size of person” test for a deal in this range, there must be a larger party and a smaller party for the test to be satisfied. As adjusted for 2026, the larger party must have total assets or annual net sales of $267.8 million or more, and the smaller party must have (i) total assets or annual net sales of $26.8 million or more (if it is a manufacturer) or, alternatively, (ii) total assets of $26.8 million or annual net sales of $267.8 million (if it is not engaged in manufacturing).

“Size of Person” Test as adjusted for 2026
Larger Party Smaller Party
Total assets [1] or annual net sales [2] of $267.8 million AND Engaged in Manufacturing: Total assets or annual net sales of $26.8 million or more OR Not Engaged in Manufacturing: Total assets of $26.8 million or annual net sales of $267.8 million or more

[1] Total assets are measured as of the last regularly prepared balance sheet of the applicable party.

[2] Annual net sales are as stated on the last regularly prepared annual statement of income and expense of the applicable party.


If the ultimate parent entities of one or both parties to the transaction in this size range ($133.9 million but less than $535.5 million) do not satisfy the applicable “size of person” thresholds, then no HSR Act notification is required. Conversely, transactions valued at more than $535.5 million will be reportable in 2026 regardless of the size of the parties, unless an HSR Act exemption applies. As always, the value of a transaction is subject to certain exceptions and calculation adjustments that can affect either the obligation to make a notification filing or the amount of the filing fee required with the filing.

HSR filing fees are also adjusted on an annual basis (based on changes in the Consumer Price Index). The 2026 filing fees, which have increased and will take effect at the same time as the 2026 thresholds, are as follows:

HSR Filing Fees as adjusted for 2026 Size of Transaction
$35,000 Less than $189.6 million
$110,000 At least $189.6 million but less than $586.9 million
$275,000 At least $586.9 million but less than $1.174 billion
$440,000 At least $1.174 billion but less than $2.347 billion
$875,000 At least $2.347 billion but less than $5.869 billion
$2,460,000 At least $5.869 billion

The maximum civil penalties for violating the HSR Act are similarly indexed, but the 2026 adjustments have not yet been announced. The  current maximum civil penalty for HSR Act violations is $53,088 per day.

Interlocking Directorates

The Federal Trade Commission also announced the revised thresholds for interlocking directorates. Section 8 of the Clayton Act generally prohibits a person from serving as a director or officer of two competing corporations if their overall size and competitive sales meet certain thresholds that are also indexed with the gross national product.

Effective upon publication in the Federal Register, Section 8’s prohibition on interlocking directorates will apply, with certain exceptions, where each corporation has capital, surplus and undivided profits aggregating more than $54,402,000, and the competitive sales of both corporations are at least $5,440,200. Competitive sales are defined as the gross revenues for all products and services sold by one corporation in competition with the other. Section 8 does not apply if the competitive sales of either corporation are less than 2% of its total sales, or if the competitive sales of each corporation are less than 4% of that corporation’s total sales.
