U.S. M&A activity expected to grow further in 2026

Following a period of slower deal-making, there are signs that global merger and acquisition (M&A) activity is recovering. Global M&A activity increased by around 40% in 2025, and investment banks expect this trend to continue into 2026. This is supported by AI-driven investment, private-equity capital deployment, and improved regulatory visibility¹.

Against this global backdrop, US M&A activity is also anticipated to regain momentum in 2026. Improving financing conditions, stabilizing valuations, and renewed strategic confidence among corporate leaders are creating a more supportive environment for transactions.

Companies are increasingly using strategic M&A to accelerate growth and strengthen their competitive position. Acquisitions enable organizations to expand their capabilities, access advanced technologies, and enter adjacent or high-growth markets. At the same time, private equity firms are under pressure to deploy capital and monetize long-held assets, thereby reinforcing the pipeline of potential transactions.

However, completing a transaction is only the beginning of the value creation process. Many organizations still struggle to realize the expected benefits after closing, particularly when it comes to integrating operations, technologies, and cultures. As deal activity increases, companies that treat post-merger integration as an operational transformation will be better placed to unlock the full value of their investments.

U.S. M&A activity is gaining momentum heading into 2026

After a subdued period for dealmaking, the U.S. mergers and acquisitions market is gradually regaining momentum as companies adjust to evolving economic conditions. Over the past two years, uncertainty surrounding interest rates, persistent inflation, and geopolitical tensions has led many organizations to delay or reassess major transactions. While financing costs remain elevated relative to pre-2022 levels, improved visibility into monetary policy and greater stability in valuation expectations are encouraging companies to revisit strategic opportunities.

Both corporate buyers and private equity firms are actively rebuilding transaction pipelines. Private equity, in particular, faces growing pressure to deploy substantial uninvested capital while also seeking exit opportunities for portfolio companies held for longer than typical investment cycles. This dynamic is likely to support deal activity as investors and strategic buyers continue searching for high-quality assets that can deliver sustainable long-term value. At the same time, corporate leaders are increasingly viewing acquisitions as a strategic lever for growth and transformation.

Although macroeconomic and geopolitical risks persist, the overall outlook points to a gradual recovery in deal activity through 2026, supported by stabilizing financial conditions, pent-up demand for transactions, and continued strategic imperatives among both financial sponsors and corporate acquirers.

Strategic acquisitions are becoming a core growth lever

In an increasingly competitive and fast-changing business environment, mergers and acquisitions are becoming a key lever for companies seeking to strengthen their growth strategy. Rather than relying solely on organic expansion, many organizations are turning to acquisitions to quickly access new capabilities, technologies, and markets.

Strategic acquisitions allow companies to respond more quickly to technological disruption, shifting customer expectations, and intensifying global competition. They also provide opportunities to strengthen core operations, diversify revenue streams, and enhance long-term resilience. M&A is increasingly viewed as a way to reposition businesses for future growth.

Acquiring technology and innovation

One of the main drivers of recent M&A activity is the need to access advanced technologies. Developing new capabilities internally can take years, particularly in rapidly evolving areas such as artificial intelligence, digital platforms, and advanced analytics. Acquiring companies with established technological expertise allows organizations to shorten innovation cycles and remain competitive.

Technology-driven acquisitions are also enabling companies to modernize their operations, enhance data capabilities, and improve productivity. For many organizations, acquiring technology has become a powerful way to transform how businesses operate.

Expanding capabilities and market reach

Strategic acquisitions also enable companies to expand their capabilities and strengthen their position in existing or new markets. Through M&A, organizations can integrate complementary products, services, or expertise that would be difficult or slow to develop internally.

In addition, acquisitions often provide access to new customer segments, geographic markets, or distribution channels. This can help companies accelerate revenue growth while increasing their scale and competitiveness. As industries consolidate, building broader capabilities through acquisitions is becoming an important corporate strategy to maintain market leadership.

Building resilience in uncertain markets

In a period marked by economic volatility, geopolitical tensions, and rapid technological change, resilience has become a key priority for corporate leaders. Strategic acquisitions can help organizations diversify their portfolios, reduce operational risks, and strengthen their ability to adapt to shifting market conditions.

Companies are increasingly pursuing acquisitions that enhance supply chain resilience, improve operational efficiency, or provide access to critical capabilities. By strengthening their operating models and expanding their strategic options, businesses can better navigate uncertainty and position themselves for long-term stability.

Sectors leading the M&A wave

Several industries are expected to remain at the forefront of M&A activity in the coming years. Technology continues to play a central role, as companies across all sectors invest in digital transformation and data-driven capabilities. Healthcare is another active area, driven by innovation in medical technologies, pharmaceuticals, and healthcare services.

Financial services and industrial sectors are also seeing increased deal activity as organizations pursue scale, operational efficiency, and new growth opportunities. In many cases, both corporate buyers and private equity investors are targeting high-quality assets capable of supporting long-term transformation and value creation.

The real risk in M&A is not the deal — it’s the integration

While significant attention is paid to identifying targets, negotiating terms and securing financing, the real challenges in mergers and acquisitions often begin after the deal closes. Many organizations have become increasingly sophisticated in executing transactions, but far fewer consistently capture the full value they expected from an acquisition.

The success of an M&A deal ultimately depends on how effectively the two organizations are integrated. Aligning operating models, processes, technologies, and cultures requires careful planning and disciplined execution. Without a structured integration approach, companies risk losing momentum after closing, delaying the realization of synergies, and reducing the overall value of the transaction.

Why expected value often fails to materialize

In many M&A transactions, the anticipated benefits—such as cost synergies, revenue growth, or improved capabilities—fail to fully materialize. One of the main reasons is that integration planning is often underestimated during the deal process. Organizations may focus heavily on financial and legal aspects of the transaction, while operational integration often receives comparatively less attention until after the deal has been completed.

As a result, the expected synergies can take longer to achieve or may never be realized. Delays in decision-making, unclear accountability, and insufficient coordination between teams can quickly erode the value that justified the acquisition in the first place.

Common post-merger integration pitfalls

Post-merger integration is a complex process that involves aligning multiple aspects of the organization simultaneously. Without a clear structure and governance model, integration efforts can become fragmented and difficult to manage.

Common pitfalls include unclear priorities, lack of dedicated integration leadership, and insufficient communication across the combined organization. In some cases, companies attempt to integrate too many initiatives at once, creating operational disruption rather than delivering value. Effective integration requires a clear roadmap, strong governance, and a disciplined focus on the initiatives that generate the greatest impact.

Cultural, operational, and technology misalignment

One of the most challenging aspects of post-merger integration is aligning different organizational cultures, operating practices, and technology systems. Even when two companies appear strategically compatible, differences in leadership styles, decision-making processes, or performance management approaches can create friction.

Operational misalignment can also slow down integration, particularly when processes, systems, or supply chains are not easily compatible. At the same time, integrating technology platforms and data systems can be both costly and time-consuming if not addressed early in the integration process.

Organizations that proactively address these cultural, operational, and technological differences are better positioned to improve integration, reduce disruption, and capture the full value of their acquisitions.

How Kaizen supports successful M&A integration

Successfully capturing the value of an acquisition requires a structured and disciplined approach to integration and operational transformation. From the early stages of evaluating a target company to the implementation of long-term improvement initiatives, organizations must ensure that operational realities, risks, and value creation opportunities are clearly understood and effectively managed.

Kaizen Institute supports companies throughout the M&A journey by focusing on the operational dimension of transactions. Through operational due diligence, structured integration planning, and long-term value-creation initiatives, organizations can reduce risk, accelerate integration, and maximize the return on their acquisitions.

Operational due diligence before the deal

One of the main challenges in M&A decisions is the lack of visibility into the target company’s true operational situation. Critical risks may be underestimated, operational inefficiencies overlooked, and potential synergies not fully identified during the early stages of a transaction.

Operational due diligence provides a comprehensive and reliable understanding of how the target organization actually functions. Conducted before an acquisition or investment decision, this analysis helps management teams assess the business’s true value and identify both risks and opportunities for improvement.

This process typically takes several weeks, depending on the organization’s complexity and data availability. During this phase, consultants examine the company’s operational model and value chain, including key areas such as processes and workflows, supply chain performance, infrastructure and equipment, information systems and technologies, human capital, and operational compliance.

By combining operational insight with strategic evaluation, operational due diligence enables decision-makers to approach transactions with greater clarity and confidence.

Designing and executing the first 100-day integration plan

Even well-structured transactions can face difficulties if integration is not carefully planned and executed. Misalignment between teams, ineffective communication, and poor change management can quickly undermine the expected benefits of an acquisition.

The first 100 days following the closing of a transaction are therefore critical. A structured 100-day integration plan provides a clear roadmap to align operations, governance, and organizational culture during the early stages of integration. Importantly, this plan should be designed before the deal closes to ensure integration can begin immediately upon completion.

The main objective of the 100-day plan is to ensure a smooth transition while maintaining operational continuity. It helps organizations align leadership teams, coordinate communication with key stakeholders, and retain critical talent within the newly combined organization. At the same time, the plan focuses on identifying and implementing quick wins and early synergies that generate tangible results and build momentum for the integration process.

By providing structure, transparency, and disciplined execution, the 100-day integration plan helps organizations minimize disruption and speed up value capture.

Building a structured value creation plan

Once the initial integration phase is complete, companies must focus on unlocking the full potential of the acquisition over the medium and long term. This requires a clear strategic vision and a structured approach to operational improvement.

A value-creation plan identifies, prioritizes, and implements initiatives that enhance operational performance and maximize return on investment. Typically implemented over several months, this plan builds on the insights generated during the due diligence phase and the early integration period.

Key initiatives often focus on improving core operational processes, capturing synergies across the combined organization, and strengthening performance management systems. At the same time, organizations work to embed a culture of continuous improvement that ensures the sustainability of results.

Through hands-on implementation and close collaboration with operational teams, Kaizen helps ensure that improvement initiatives move beyond strategy and deliver measurable results. This structured approach enables organizations to transform acquisitions into long-term drivers of growth, efficiency, and sustainable value creation.

Turning M&A growth into sustainable value

As M&A activity gains momentum, companies increasingly recognize that the true success of a transaction is determined not at signing, but in the months and years that follow. While acquisitions can create significant opportunities for growth, innovation, and market expansion, realizing their full potential requires disciplined execution and a strong focus on operational integration.

Companies that treat integration as an operational transformation are better positioned to align processes, technologies, and teams while maintaining business continuity. This approach allows organizations to move beyond short-term integration challenges and build a stronger, more efficient combined organization.

As the deal environment evolves in 2026, the ability to translate strategic acquisitions into tangible operational improvements will become an increasingly important differentiator. Companies that prioritize structured integration, clear governance, and continuous improvement will be better equipped to unlock the full value of their investments.

By combining rigorous due diligence, disciplined integration planning, and a long-term focus on operational excellence, organizations can transform acquisitions into sustainable drivers of performance, resilience, and growth.
