The New Rules of M&A
M&A entered 2026 on firmer footing, but not on easier terms. After a slower period, global deal value rebounded sharply in 2025, rising to roughly USD 4.7–4.9 trillion, while overall deal volume remained broadly stable. The message is clear: the recovery was driven more by larger transactions than by a broad reopening of the market.
That matters because it reveals the new shape of competition. Confidence has returned, but execution has become more selective. Capital is concentrated in the hands of the best-capitalized buyers, private credit has increased financing flexibility, and debt costs continue to reward discipline over optimism. In many processes, the distinction between a bid that is merely attractive and one that offers real certainty of closing has become decisive.
This strengthens the premium for scale. Larger buyers benefit not only from deeper capital access but from greater organizational readiness: they can move faster, validate financing earlier, and present a more credible post-acquisition plan. In competitive auctions, that increasingly matters as much as price. Sellers are not simply choosing the highest valuation; they are weighing speed, certainty, confidence that the buyer can execute, and the credibility of the future vision presented for the business. Where continuity, growth ambition, and the long-term positioning of the company matter, that vision can meaningfully influence the final choice of buyer.
The effect is especially visible in the mid-market. Across many sectors, rising requirements in technology, cybersecurity, quality, and operational resilience are lifting the fixed cost base. For many mid-sized businesses, those costs are increasing faster than their ability to spread them across revenue. At the same time, financing constraints and valuation gaps remain persistent. The result is a structural advantage for better-capitalized consolidators and growing pressure on mid-market companies to seek scale. In that environment, consolidation is no longer optional. It is becoming the practical response to a scale premium that is now built into market economics.
Why Repeatability Matters
The instinctive response to a scale premium is often to pursue a single transformational acquisition. But in 2026, size also brings friction. Large deals face longer paths to closing, more regulatory scrutiny, and greater exposure during the period between signing and completion.
That is one reason repeatable consolidation is gaining renewed appeal. A series of smaller acquisitions can build scale with less disruption, shorter integration cycles, and more room to adjust as assumptions change. In volatile conditions, that flexibility is not a secondary benefit; it is part of the value proposition.
This is the logic behind the return of programmatic M&A. Research has repeatedly shown that companies executing multiple smaller acquisitions through a consistent strategy often outperform those relying on occasional large deals. But the advantage does not come from deal count alone. Repeatability creates value only when it becomes an organizational capability.
That capability starts with a clear investment thesis and disciplined target selection. It requires defined rules for evaluating strategic fit, synergies, integration complexity, and downside risk. It also depends on a decision model that can be applied repeatedly without reducing quality. In other words, programmatic M&A works not because it is more active, but because it is more systematic.
The due diligence model is evolving accordingly. Traditional legal and financial review remains necessary, but it is no longer sufficient. Buyers are placing greater weight on value diligence: identifying the specific levers that can be activated after closing, testing how quickly they can be realized, and assessing the operational burden of integration. Where complexity is high and preparation is weak, integration debt can accumulate quickly. In a higher-cost-of-capital environment, that risk is harder to absorb.
Analytical tools are supporting this shift. The use of generative AI in M&A processes is rising rapidly across both corporates and financial sponsors. These tools do not replace judgment, but they do increase throughput, improve consistency across workstreams, and help structure knowledge embedded in large volumes of transaction material. That matters most in repeatable acquisition models, where speed and consistency often determine whether the platform scales efficiently or becomes overstretched.
Buy-and-Build 2.0: From Multiple Arbitrage to Operational Value Creation
The same forces are reshaping buy-and-build. The model remains highly relevant in 2026, but its economics are changing. A prolonged period of higher rates and more expensive leverage has made it harder to rely on multiple expansion as the primary engine of returns. Platforms built mainly on valuation arbitrage now face a more demanding exit environment.
That is why buy-and-build is evolving into something more operational. Buy-and-build 2.0 is not about assembling assets and waiting for the market to rerate them. It is about turning acquisitions into a platform with demonstrable operating advantages.
That means the logic of the deal must be translated into execution. Procurement synergies, shared services, pricing discipline, data standardization, technology harmonization, and productivity gains cannot remain in the investment memo. They must be delivered in practice. At the same time, scope benefits are becoming more important. Cross-sell, expanded service offerings, and stronger retention are increasingly central to the equity story because they support faster, more visible value creation. In many sectors, commercial integration now matters as much as cost integration.
The continued dominance of add-on acquisitions confirms how far the market has moved in this direction. In Europe, add-ons have represented more than half of buyout activity for years, and their share of control deals remained high in 2025. That has two implications. First, integration must be treated as a continuous capability rather than a one-off project. Second, people and culture become strategically important. A platform completing multiple acquisitions in a short time can lose coherence quickly unless governance, decision rights, and operating standards are clearly defined.
This is particularly relevant in specialist services, where consolidation often responds directly to fragmentation and client demand for broader solutions. In these markets, value is not created simply by adding revenue streams. It is created through professionalization: standardizing processes, improving quality control, aligning technology, and actively shaping the service portfolio. That is where buy-and-build 2.0 shows its real advantage. Instead of depending on market rerating, the platform builds a competitive position that can justify a premium because it is grounded in operating performance.
The One-Stop-Shop Effect
The premium for scale is increasingly reinforced by a premium for completeness of offering. In a more uncertain environment, customers often prefer providers that can deliver a broader share of the value chain with greater consistency. The one-stop-shop model has therefore become more than a commercial ambition; it is also a margin-generation tool, as greater control over the value chain allows a business to capture more of the margin pool for itself. Instead of leaving value with multiple independent providers, the platform can internalize a larger share of profit across the chain.
From an M&A perspective, this drives two complementary forms of consolidation. Vertical integration improves control over cost, quality, timelines, and resource availability. Horizontal integration builds scale, expands geography, strengthens bargaining power, and supports more consistent customer delivery. The strongest platforms increasingly combine both.
Cross-border expansion remains part of this logic, but with greater selectivity. In many sectors, domestic markets alone no longer provide sufficient growth, and fragmentation still creates opportunities beyond national borders. Yet recent deal patterns suggest that the highest value is often created within the same broader region, where regulatory, cultural, and operating differences are more manageable. In 2026, cross-border consolidation is not disappearing; it is becoming more thesis-driven and less opportunistic.
That selectivity is reinforced by regulation and timing. Longer closing periods, greater scrutiny, and higher carry costs all reduce the appeal of large, complex transactions unless the strategic rationale is exceptionally strong. Buyers able to build scale through a sequence of acquisitions therefore gain an important advantage: they can keep moving while others are tied up in long and uncertain processes.
This is why programmatic M&A and buy-and-build 2.0 are increasingly converging. Both rely on repeatability, disciplined integration, and operational delivery. Both favor buyers who can compound advantages over multiple transactions rather than depend on one defining deal.
What This Means for Buyers and Sellers
For buyers seeking to become local champions, the implication is straightforward: M&A must become a capability, not an event. That requires a clear consolidation thesis, but also governance, talent, metrics, and decision processes that can support a sustained pace of acquisitions without undermining quality. In this model, integration is not what happens after the deal. It is the main mechanism of value creation.
For sellers, especially in the mid-market, the standard is rising as well. Buyers increasingly assess assets through the lens of integration readiness: data quality, earnings visibility, process maturity, technology compatibility, and the stability of key teams and customer relationships. Where those elements are weak, valuation pressure tends to appear not only in headline price, but in structure, conditions, and timing.
The common denominator of winning strategies in 2026 is therefore not simply scale, but repeatable scale. The market has recovered in value, but not in ease. Capital remains selective, mistakes remain expensive, and execution is priced in more heavily than before. In that environment, the winners will not be the buyers able to announce the boldest transaction. They will be the ones able to acquire, integrate, and scale repeatedly, with discipline.
Buy-and-build 2.0 is the clearest expression of that shift. It replaces dependence on financial engineering with an operating model built for consolidation. And in a market defined by polarization and the premium for scale, that repeatability is becoming one of the few advantages that compounds
