Global M&A Hits $2.6 Trillion in 2025, Fueled by AI and Growth Ambitions

Key Points:
– Global M&A value reaches $2.6 trillion YTD, the highest since the 2021 post-pandemic surge.
– AI, big tech, and private equity lead activity despite fewer total deals and tariff tensions.
– U.S. megadeals and renewed corporate confidence drive optimism for more deals ahead.

Global mergers and acquisitions (M&A) activity has surged to $2.6 trillion year-to-date, making 2025 the most active year since the 2021 boom, as companies aggressively pursue growth and innovation—particularly in artificial intelligence. The total value of deals has risen 28% from the same period last year, even though the actual number of transactions is down 16%, according to data from Dealogic.

Several U.S. megadeals have fueled the resurgence, including Union Pacific’s proposed $85 billion acquisition of Norfolk Southern and OpenAI’s massive $40 billion funding round led by Japan’s SoftBank. These transactions signal a bold appetite for scale and future-proofing in the face of evolving technologies and regulatory dynamics.

What’s driving this momentum? Experts say companies are seeking to stay ahead in a transformative AI race, while adapting to a more settled political and regulatory environment following the initial uncertainties surrounding the Trump administration’s trade tariffs and antitrust posture.

Private equity has also re-entered the scene with major moves. Examples include Sycamore Partners’ $10 billion buyout of Walgreens Boots Alliance and Advent’s revised $6.4 billion bid for UK firm Spectris. These moves show that buyout firms are growing confident in valuations and exit opportunities once again.

While healthcare led the charge in previous years, technology and electronics are now driving deal volume, especially in the U.S. and UK. Notable moves include Samsung’s $1.7 billion acquisition of FlaktGroup, which specializes in data center cooling—an essential infrastructure for AI systems.

The largest deal in EMEA this year came from Palo Alto Networks, which acquired Israeli cybersecurity company CyberArk for $25 billion. Rising AI-driven threats have made cybersecurity a top priority, prompting record valuations in the space.

Looking ahead, dealmakers at JPMorgan and other institutions remain bullish. The combination of AI demand, digital infrastructure needs, and steady leadership in corporate boardrooms suggests that the second half of 2025 could see even more high-profile M&A activity.

Novartis to Acquire Regulus Therapeutics in $1.7 Billion Biotech Buyout

Key Points:
– Novartis to acquire Regulus for up to $1.7B, including $7/share upfront and $7/share tied to farabursen approval.
– Farabursen, a potential first-in-class ADPKD treatment, heads into Phase 3 with FDA alignment.
– Boosts Novartis’s kidney disease pipeline and commitment to innovation in rare conditions.

Novartis AG announced plans to acquire Regulus Therapeutics Inc. in a transaction valued at up to $1.7 billion, reinforcing the Swiss pharmaceutical giant’s strategy to deepen its portfolio in renal and genetic disease treatments. The deal includes an upfront cash payment of $7.00 per share, representing approximately $800 million in equity value, and an additional $7.00 per share tied to a regulatory milestone via a contingent value right (CVR), pending approval of Regulus’s lead drug candidate, farabursen.

Farabursen is being developed as a novel treatment for autosomal dominant polycystic kidney disease (ADPKD), a condition with limited current options and significant unmet clinical need. If approved, farabursen could become the first systemic therapy of its kind in this indication, offering a potentially superior safety and efficacy profile compared to existing treatments.

The acquisition reflects a growing trend in the biopharma sector where large-cap pharmaceutical companies pursue innovative pipelines through targeted M&A. In recent quarters, the industry has seen an uptick in transactions focused on small to mid-sized biotech firms that specialize in high-impact therapies for rare or underserved diseases. Regulus’s focus on microRNA-based therapies, a field once viewed as experimental, is now receiving renewed attention as advances in RNA technology improve target precision and therapeutic delivery.

For Novartis, the move expands its nephrology franchise and bolsters its pipeline in genetic disorders, aligning with the company’s long-term innovation strategy. Financially, the deal signals confidence in both Regulus’s platform and farabursen’s development prospects. The 274% premium to Regulus’s 60-day volume-weighted average price underscores the strategic value Novartis sees in the program.

The transaction is expected to close in the second half of 2025, subject to regulatory approval and the successful tender of a majority of Regulus’s outstanding shares. Once finalized, Regulus will become a wholly owned subsidiary of Novartis, with its operations and development programs integrated into Novartis’s global R&D structure.

The deal may also serve as a bellwether for continued consolidation in biotech, particularly among companies advancing oligonucleotide or RNA-based therapeutics. Investors are likely to see the acquisition as further validation of microRNA platforms, potentially reinvigorating interest in similar early-stage biotech firms.

At a time when cost pressures and generic competition are accelerating across the pharmaceutical landscape, acquiring promising assets with a clear regulatory path remains a preferred strategy for growth. For Regulus, integration with Novartis offers the financial and operational muscle needed to take farabursen through the final stages of development and, if approved, to global markets.

As the biotech sector continues to recalibrate from recent valuation contractions, strategic acquisitions like this illustrate the enduring value of focused innovation, especially in areas with limited treatment alternatives and high unmet demand.
