Hart-Scott-Rodino Annual Report 2025: 2,006 Transactions

The United States of America Times, a neutral, data-driven newsroom, reports on the latest developments shaping technology and markets in the United States. On July 2, 2026, the Department of Justice and the Federal Trade Commission released the 48th Hart-Scott-Rodino Annual Report for Fiscal Year 2025, a joint document detailing premerger activity across the U.S. economy and offering a lens into how merger review is evolving in a high-velocity tech landscape. This release marks a milestone in public accounting of premerger activity, providing policymakers, market observers, and industry participants with a comprehensive ledger of transactions that could affect competition. According to the agencies’ joint report, the premerger notification program tracked trillions of dollars in deal value and hundreds of deals that could reshape key sectors, including technology, healthcare, and energy. The public record offers both a snapshot of the year’s merger activity and a baseline for assessing future antitrust policy and enforcement priorities. For readers and researchers tracking competition policy, this release matters because it translates regulatory oversight into tangible data about market concentration and potential consumer impact. The Hart-Scott-Rodino process remains a central mechanism for safeguarding competition in fast-moving technology markets, and the 2025 report provides the most current, formal accounting of how those protections were exercised during the year.

The Hart-Scott-Rodino Annual Report for Fiscal Year 2025 covers the period October 1, 2024, through September 30, 2025, and summarizes the agencies’ merger enforcement efforts, thresholds, and program changes. In FY2025, the agencies audited and cataloged a broad set of premerger activity, with the report highlighting the number of reportable transactions, the dollar values involved, and the enforcement actions undertaken to preserve competitive markets. The public documentation emphasizes that while many deals proceed with standard waiting periods, a non-trivial share of transactions trigger in-depth scrutiny, second requests, and, in some cases, structural remedies or litigation. The joint report’s data-rich presentation is designed to equip policymakers, business leaders, and the public with a clear sense of how the antitrust regime applied to mergers in a year characterized by mega-deals in technology and national-scale market shifts. The following analysis distills the year’s key facts, explains why they matter for technology and market trends, and outlines what to watch next as regulators reexamine thresholds, forms, and enforcement approaches. The numbers and events cited in this piece draw directly from the official FY2025 Hart-Scott-Rodino Annual Report and the corresponding agency press materials released in July 2026, which are linked in the sources at the end of this piece. The Hart-Scott-Rodino Annual Report 2025 is the subject of this reporting, and readers should consult the primary documents for exact figures and methodological notes. (ftc.gov)

Opening lift: According to the Hart-Scott-Rodino Annual Report for Fiscal Year 2025, released July 2, 2026, the agencies recorded 2,006 HSR transactions in FY2025, with about 31.8% valued at $1 billion or more. This single-line finding, drawn from the official report, is the cornerstone of today’s data-driven view of merger activity in the United States, and it sets the stage for deeper analysis of sectoral patterns, enforcement intensity, and policy implications. In other words, a year that already looked transformative in technology and healthcare by public market signals is now quantified in formal federal records, providing a concrete baseline for evaluating how competition is faring in the face of mega-deals and strategic consolidations. The public record reinforces that the premerger notification program, in its current form, continues to function as a critical early warning system for potential anticompetitive effects across the economy. For readers who want to verify the exact figures and methodology, the primary sources discussed below include the official Hart-Scott-Rodino Annual Report for Fiscal Year 2025 and the companion agency press releases.

Section 1: What Happened

Overview of the FY2025 HSR Report

The joint Hart-Scott-Rodino Annual Report for Fiscal Year 2025 was issued by the Federal Trade Commission (FTC) and the Department of Justice (DOJ) Antitrust Division to document the agencies’ merger enforcement efforts and to provide fiscal-year data on the Premerger Notification Program. The document covers a 12-month period from October 1, 2024, through September 30, 2025, and presents a structured accounting of reportable transactions, the distribution of deal values, enforcement actions, and public engagement with industry and the public. The report emphasizes that while many mergers proceed through standard review channels, a meaningful subset involves second requests, investigations, and potential remedies that can shape competitive outcomes. The report also highlights threshold adjustments and rulemaking developments that influence what counts as a reportable transaction and how the agencies prioritize cases. Readers should note that the fiscal year 2025 assessment includes a mix of high-profile technology and healthcare deals as well as numerous smaller transactions across diverse sectors. The document’s framing of “developments and ongoing assessment” points to a regulatory posture that remains vigilant about evolving market structures, particularly in tech and digital markets where scale and network effects can magnify competitive effects. The official PDF is the definitive source for the year’s statistics and is available as the 48th Hart-Scott-Rodino Annual Report for Fiscal Year 2025. (ftc.gov)

Key Metrics and What They Imply

Total HSR transactions in FY2025: 2,006. This figure represents the number of reportable premerger notifications that the combined FTC-DOJ program processed, reflecting both large and smaller deals across the economy. The report’s Table I and Exhibit A lay out this total, along with adjustments for certain transactions that were not eligible for Second Requests. The baseline figure is 2,006, with adjustments described in the report’s footnotes to account for reporting nuance. The official document notes that the baseline figure is adjusted for Second-Request eligibility, but 2,006 remains the key headline number for the year. (ftc.gov)
Share of transactions valued at $1 billion or more: 31.8%. This share indicates the ongoing prevalence of “mega-deals” in the HSR universe, signaling that a sizable portion of reportable mergers involved substantial financial scale and potential competitive implications. The calculation arises from the report’s Exhibit A data, which shows the percentage of transactions by value category and the corresponding counts. The 31.8% figure aligns with the trend toward higher-value deals in recent years. (ftc.gov)
Aggregate dollar value of reported transactions: $2.5 trillion. The report documents that the total value of transactions reported under the HSR Act for FY2025 summed to roughly $2.5 trillion, underscoring the scale of activity in the premerger notification program and the breadth of markets affected by potential mergers. The $2.5 trillion figure appears in the narrative discussion of the data and is corroborated by the accompanying exhibits that break down values by category and sector. This is a key indicator of market concentration risk and the potential magnitude of competitive effects. (ftc.gov)
Enforcement actions: FTC took eight merger-related actions; DOJ took ten; totaling 18 actions in fiscal year 2025. The split of enforcement activity across agencies highlights the continued collaboration between the FTC and DOJ in addressing merger-related concerns across sectors, with a mix of litigation, consent decrees, and abandonments resulting from agency scrutiny. The report’s enforcement section details these actions and their nature, demonstrating a broad portfolio of cases across healthcare, technology, energy, defense, consumer goods, and services. (ftc.gov)

Notable cases highlighted in the FY2025 report reflect the central role of technology and life sciences in the antitrust review process. For example, the report discusses Edwards Lifesciences Corp.’s proposed acquisition of JenaValve Technology, Inc. and the ensuing litigation and remedies designed to protect competition in a high-stakes medical devices segment. It also surveys post-filing actions in the digital-ad and real estate tech spaces, including the Zillow, Inc. and Redfin Corporation matter, which showcased the agencies’ willingness to challenge or constrain arrangements that might affect online marketplaces and consumer choice. The report uses these examples to illustrate how the agencies translate broad policy objectives into concrete enforcement actions during the year. The Edwards-Lifesciences/JenaValve and Zillow/Redfin cases are cited in the public materials and illustrate the range of interventions used to maintain competitive dynamics in two distinctly different technology-driven markets. (ftc.gov)

Threshold adjustments and form rule developments are another throughline in FY2025. The Agencies emphasize threshold adjustments required by statute and discuss the implementation of the final HSR Form rulemaking, which was vacated by the Eastern District of Texas and remains on appeal. These developments affect which deals are reportable and how the agencies staff and manage the review process. The report explains that threshold changes can shift the universe of reportable deals and thus influence future enforcement focus. In particular, the January 2025 notice to reflect threshold adjustments demonstrates the ongoing calibration of the premerger regime to reflect inflation and market dynamics. The effect is not merely procedural; it reshapes the price and scope of what deals require formal premerger notification. (ftc.gov)

Public engagement and global context are given attention in the FY2025 report as well. The Premerger Notification Office (PNO) staff continued outreach to industry participants, providing guidance on reportability, filing requirements, and thresholds. The report also situates U.S. enforcement activity in a broader international context, noting that competition authorities around the world monitor and, in some cases, coordinate responses to large, cross-border mergers. The international dimension is framed as part of a broader ecosystem of competition policy that can amplify or influence U.S. actions when global market players intersect with U.S. markets. These elements, while not as quantifiable as transaction counts, matter for readers trying to understand the regulatory environment for technology platforms and multinational mergers. (ftc.gov)

Section 2: Why It Matters

Why the FY2025 Data Reshapes Our View of Competition in Tech and Markets

The Hart-Scott-Rodino Annual Report 2025 offers a data-rich view that helps analysts and policy professionals assess whether the U.S. merger review system is keeping pace with the dynamics of modern markets, particularly in technology, healthcare, and digital platforms. The 2,006 transactions recorded in FY2025, coupled with the fact that 31.8% of these deals were valued above $1 billion, signals that the market environment is characterized by frequent high-value transactions. This reality has implications for competition in digital ecosystems, where large-scale acquisitions can reshape platform dynamics, raise barriers to entry, and alter innovation trajectories. The data also underscores that mega-deals are not confined to one sector; healthcare and technology remain prominent in the enforcement landscape, even as other industries see meaningful activity in the more traditional manufacturing and energy spaces. The report’s narrative highlights the continuing relevance of the HSR Act as a screening mechanism that can alter the course of an acquisition before it closes, thereby potentially preventing market distortions that could harm consumers in the long run. The 2025 data set—when interpreted alongside enforcement actions—offers a picture of how aggressive or measured the agencies intend to be with respect to large, value-heavy mergers that could meaningfully affect competition in multiple sectors. The inclusion of threshold updates and form rule developments further clarifies the regulatory guardrails that shape which deals reach the regulatory stage and how those deals are scrutinized. (ftc.gov)

Sectoral Implications: Technology, Healthcare, and Beyond

Technology and healthcare stand out in the FY2025 narrative not only because of the size of some transactions but also because of the direct public health and consumer welfare implications embedded in many of these deals. The Edwards Lifesciences/JenaValve example demonstrates how merging entities in highly specialized medical device markets can draw a court’s attention to potential reductions in innovation or competition. In technology, the presence of transactions valued over $1 billion—and the fact that the aggregate deal value is in the trillions—signals ongoing consolidation in sectors dependent on platform-enabled services, AI, and cloud infrastructure. These dynamics matter to policymakers deciding how to calibrate enforcement resources and to corporate strategists evaluating whether to pursue aggressive growth via acquisitions or to seek remedy-based paths that preserve competitive options for customers and smaller players. The FY2025 report highlights that enforcement actions are not limited to blockbuster megadeals but also include consent orders and other remedies aimed at preserving competitive balance in key markets. The Zillow/Redfin matter, while focused on online real estate marketplaces, touches on how digital competition concerns translate into consumer outcomes, including pricing transparency, platform neutrality, and the quality of search and match services. In sum, the data points within the report illuminate a broad set of concerns spanning technology-enabled services, health innovation, and consumer markets that rely on robust competition to foster innovation and affordability. (ftc.gov)

Policy and Enforcement Context: Thresholds, Rulemaking, and Public Engagement

The Hart-Scott-Rodino Annual Report 2025 is not only a numeric ledger; it is a policy instrument that reveals how the antitrust regime is adapting to evolving market structures. The threshold adjustments enacted in 2025 and the status of the final HSR Form rulemaking—vacated by a federal court and awaiting appeal—signal an environment where the cost and complexity of premerger notification can shift meaningfully from year to year. This matters for technology firms with fast product cycles and for investors who rely on regulatory clarity to gauge merger feasibility and timing. Public engagement and transparency remain central themes; the PNO has continued its outreach to industry and the public to explain how to file, what constitutes a reportable transaction, and how the waiting periods operate. This ongoing dialogue between regulators and market participants is a hallmark of a mature, rule-based approach to competition policy, one that seeks to balance timely notification with robust analysis of potential competitive harm. The FY2025 report makes explicit that threshold changes and rules keep pace with inflation and market evolution, a practice that affects who must report and how thoroughly reviews are conducted. (ftc.gov)

The Broader Competitive Landscape: Interagency Collaboration and Global Context

The joint nature of the Hart-Scott-Rodino Annual Report underscores a coordinated federal approach to merger review—an approach that leverages the strengths of both the FTC and the DOJ Antitrust Division. The collaboration is not just procedural; it yields a combined dataset that informs public and private decision-making, from corporate strategy to legislative oversight. The report’s discussion of international context—recognizing competition authorities around the world and the possible cross-border implications of large U.S.-centric transactions—provides a reminder that U.S. merger control operates within a global ecosystem. For technology platforms and digital markets, cross-border activity is common, and regulators increasingly consider how actions in one jurisdiction interact with others to shape global competition. The FY2025 report thus serves as a bridge between domestic enforcement actions and transnational market dynamics, a point that matters for multinational corporations charting growth in the technology space. (ftc.gov)

Section 3: What’s Next

Near-Term Developments and Key Watchpoints

Looking ahead, several developments in the Hart-Scott-Rodino regime warrant close attention. First, threshold adjustments and the ongoing rulemaking around the HSR Form will continue to influence what deals must be reported and how quickly they are reviewed. The January 2025 notice to adjust thresholds—consistent with the statute’s requirement to update reporting limits based on prior-year GNP or national product measures—will affect the universe of reportable transactions in 2026 and beyond. The Eastern District of Texas vacatur of the final HSR Form rulemaking adds a layer of legal uncertainty that regulators and industry participants will watch closely as the appellate process unfolds. In practical terms, that means some deals that otherwise would be reported might experience different timing or scrutiny, while others may be restructured to accommodate the evolving rule set. Public engagement activities will likely continue to be a priority for both agencies as they explain policy changes, respond to industry questions, and publish updates on thresholds, exemptions, and guidance for filers. The FY2025 report’s emphasis on developments and ongoing assessment foreshadows a period of policy refinement and administrative learning as the agencies respond to a changing market environment. (ftc.gov)

Operational and Market Implications for Stakeholders

For technology companies and other large entrants, the data in the Hart-Scott-Rodino Annual Report 2025 can inform strategic planning in several ways:

Compliance readiness: The ongoing emphasis on thresholds and the rulemaking process signal that firms should maintain robust internal diligence on whether proposed transactions meet HSR reporting obligations. The PNO’s public-facing materials emphasize that even with large-scale digital platforms, precise reporting depends on a combination of transaction value, structure, and the parties involved. Firms should ensure that internal teams stay current with threshold changes and the evolving form requirements. The FY2025 report’s discussion of threshold adjustments is a key guidepost for corporate compliance programs. (ftc.gov)
Deal design and remedies: The enforcement actions cataloged in the report show the spectrum of remedies that regulators have used to preserve competition, ranging from consent orders to divestitures and, in some cases, litigation. For executives designing strategic transactions in technology and adjacent sectors, understanding the historical use of such remedies can inform negotiation positions and potential settlements. The Edwards Lifesciences/JenaValve case provides a concrete example of how consent orders and divestitures can preserve competitive dynamics in specialized markets, while the Zillow/Redfin matters demonstrate attention to platform-level competition concerns in digital marketplaces. (ftc.gov)
Market signals for capital allocation: The aggregate value of reported transactions—approximately $2.5 trillion in FY2025—highlights the scale of dealmaking in the U.S. economy. Private equity investors, corporate strategists, and venture capital participants can use this data to calibrate expectations about funding flows, consolidation risk, and potential regulatory friction in technology ecosystems where large-scale deals are common. The sheer magnitude of the reported value supports the view that regulatory scrutiny is a meaningful gatekeeper in major technology and platform-driven sectors. (ftc.gov)
