Mergers and acquisitions (M&A) continue to be a key strategy for growth across various industries, from technology to healthcare. However, heightened antitrust scrutiny is reshaping how companies approach their M&A strategies. As the U.S. Federal Trade Commission (FTC) and Department of Justice (DOJ) increase their efforts to block or delay deals with potential anti-competitive effects, businesses must carefully navigate evolving regulatory frameworks to ensure their transactions comply with antitrust laws. This scrutiny, particularly in 2025, has intensified, requiring companies to understand the impact of competition regulations as they plan their next moves in the M&A space.
M&A Landscape: Trends and Deal Volume
Despite economic uncertainties, global M&A activity is experiencing a steady rebound, with significant transactions occurring in sectors like technology, healthcare, and finance. According to data from Refinitiv, global deal volume reached approximately $4.6 trillion in 2024, a 6% increase from the previous year. In 2025, this trend is expected to continue as industries continue to consolidate to address digital transformation challenges and global economic pressures.
-
Technology: The technology sector remains a hotbed for M&A, with major players continuing to consolidate as they race to innovate. The emergence of AI, cloud computing, and cybersecurity technologies is driving a wave of consolidation. In the first quarter of 2025, the volume of M&A deals in the tech space alone surpassed $150 billion, marking a significant year for the sector.
-
Healthcare: Healthcare also sees robust M&A activity as companies work to scale in response to regulatory pressures and rising costs. In early 2025, healthcare M&A activity exceeded $50 billion, driven by pharmaceutical companies and health insurers looking to expand their portfolios.
-
Cross-Border Transactions: Cross-border M&A activity is on the rise, especially as companies look to expand into new geographic markets. As of 2025, cross-border deals account for approximately 30% of global M&A activity, demonstrating the increasing importance of international consolidation.
Antitrust Challenges: Regulatory Scrutiny on the Rise
As M&A deals rise, antitrust scrutiny is becoming more intense. The U.S. FTC and DOJ have ramped up efforts to block or delay mergers that may harm competition or create monopolies. Under the leadership of FTC Chair Lina Khan and DOJ Antitrust Chief Jonathan Kanter, there has been a marked shift toward more aggressive enforcement of antitrust laws.
-
Microsoft-Activision Blizzard: The Microsoft-Activision Blizzard merger, valued at $69 billion, is one of the most prominent examples of recent antitrust challenges. In 2024, the FTC filed a lawsuit to block the deal, arguing that it would stifle competition in the video game industry, especially with the dominance of Microsoft’s Xbox and the potential impact on Sony’s PlayStation. The merger is currently under review, and a final decision is expected in the second half of 2025.
-
JetBlue-American Airlines: Another high-profile case involves the proposed merger between American Airlines and JetBlue. The DOJ sued to block the deal in 2021, citing concerns that the merger would reduce competition and lead to higher prices for consumers in key U.S. routes. The case is ongoing, and the DOJ has yet to make a final ruling on whether it will allow the merger to move forward.
These cases, among others, illustrate the growing scrutiny on mergers and acquisitions, particularly those involving large corporations in concentrated markets.
Legal Strategies: Ensuring Compliance with Antitrust Laws
As regulatory scrutiny intensifies, companies must take steps to ensure their M&A deals comply with antitrust laws. Here are some key strategies for businesses:
-
Early Economic Impact Assessments: Before announcing a merger or acquisition, it is essential to conduct a thorough economic analysis to assess the potential effects on competition. By assessing market concentration and consumer impact early, companies can anticipate regulatory concerns and address them proactively.
-
Engaging with Regulators: In today’s climate, early engagement with regulators is essential. Many companies now seek informal guidance from the FTC and DOJ before submitting formal merger filings. This approach can provide companies with insight into the regulatory concerns that may arise and allow them to structure the deal accordingly.
-
Divestitures: In some cases, companies may choose to divest certain assets or business units to alleviate antitrust concerns. This strategy was used in the 2020 merger of T-Mobile and Sprint, where the companies agreed to sell off some of their assets to maintain competition in the wireless market.
-
Collaborative Remedies: In high-profile mergers, companies may negotiate “behavioral” remedies, such as pledges to maintain certain competitive practices, or structural remedies like the divestiture of overlapping assets to mitigate the effects of the deal on competition. Proactive negotiation and compromise are key strategies to successfully navigating the merger review process.
Case Study: Amazon’s Acquisition of Whole Foods
A notable example of a merger that faced intense antitrust scrutiny was Amazon’s acquisition of Whole Foods in 2017. The $13.7 billion deal attracted attention due to Amazon’s potential to disrupt the grocery market with its vast distribution network and technological resources. The FTC conducted a thorough review of the merger and ultimately approved the deal without imposing significant conditions.
However, the merger serves as a reminder of how even seemingly straightforward deals are subject to scrutiny, particularly when large tech companies are involved. While the Amazon-Whole Foods merger was cleared, it still serves as a case study in navigating antitrust regulations, as Amazon had to address concerns over market competition and its potential influence on local grocery stores.
Global Antitrust Concerns: Antitrust in the EU and Beyond
Antitrust enforcement is not limited to the U.S.; the European Union (EU) has long taken a strong stance against anti-competitive practices, and this trend is expected to continue. In 2025, the European Commission is increasingly focused on “killer acquisitions”—where dominant companies acquire smaller competitors to stifle innovation. In fact, the EU blocked the $2.2 billion merger between two major European telecom firms, T-Mobile and Orange, arguing that it would have resulted in less competition and higher prices for consumers.
-
Google-Fitbit: Another significant global case involves the European Commission’s investigation into Google’s $2.1 billion acquisition of Fitbit in 2020. The European Commission raised concerns that the deal would allow Google to leverage vast amounts of sensitive health data to undermine competition in the digital health sector. The deal was approved in 2021, but only after Google agreed to impose restrictions on the use of Fitbit data.
-
Cross-Border Regulations: Companies pursuing cross-border M&A deals must consider the regulatory frameworks of multiple jurisdictions. For example, in China, antitrust scrutiny has become increasingly rigorous, with regulators rejecting several high-profile mergers in recent years. Likewise, in India, antitrust authorities have blocked mergers in the e-commerce and tech sectors due to concerns over reduced competition.
Conclusion
As mergers and acquisitions continue to be a critical strategy for growth in 2025, navigating the complex and evolving landscape of antitrust laws has never been more critical. With regulatory agencies in the U.S., the EU, and other jurisdictions becoming more aggressive in blocking or conditioning deals, businesses must be proactive in understanding and addressing potential anti-competitive concerns. By conducting early economic assessments, engaging with regulators, and being prepared to make adjustments to deal structures, companies can mitigate risks and ensure that their M&A transactions align with antitrust regulations, avoiding costly delays or rejections.
