The Acquisition Muscle Most Companies Have Not Yet Built
Why M&A success depends on the condition of the acquirer—not only the quality of the target
The old warning about mergers and acquisitions was simple: most deals fail.
The current evidence tells a more useful story. Twenty years ago, Bain's surveys found that approximately 60% of deals failed to meet executives' internal expectations. Today, executives report that close to 70% succeed, but the improvement is uneven. Bain finds that frequent acquirers outperform companies that remain inactive and describes experience as the strongest predictor of acquisition success. Companies that get better at M&A are not simply choosing better targets. They have developed more sophisticated diligence, dedicated deal capabilities, stronger integration practices, and the discipline to learn from one transaction and apply that learning to the next.
BCG reached a similar conclusion in its 2026 analysis of nearly 1,300 large public-to-public transactions. The median deal was roughly value-neutral, while a relatively small group produced most of the value destruction. Two factors consistently shaped the risk: the readiness of the acquirer and the complexity of the transaction. The issue is whether this acquirer is prepared for this transaction.
The transaction tests the buyer
Traditional diligence appropriately examines the company being acquired. Financial, legal, commercial, tax, technology, cybersecurity, and operational advisors collectively work to determine what the target owns, what it earns, what obligations it carries, and whether the investment thesis is sound.
But, and this is a big but, the changes required of an acquisition will not take place only inside the target. They also occur inside an acquirer with its own leadership capacity, decision habits, governance maturity, operating constraints, cultural patterns, and unresolved dependencies. An attractive target and a credible financial thesis cannot compensate for an acquirer that lacks the capacity to execute what the deal assumes.
The leadership team may already be stretched. The chief executive may be both deal sponsor and the point through which most important operating decisions flow. The people selected to lead the integration may also be the people most essential to protecting the base business. Decision authority may be widely understood but nowhere explicitly established. Processes that work at the company's current size may not survive the additional complexity. None of these conditions automatically makes the acquisition a bad idea. But each changes what the transaction will require. Practices that are implicitly understood inside the acquirer may be invisible to the target’s leaders and employees, making roles, authority, and expectations less clear precisely when the combined organization needs them to be explicit.
M&A capability is built, not declared
Experienced acquirers do not possess a universal integration playbook. Bain notes that leading integrators recognize the unique needs of each deal and focus on the decisions that will create value. Their advantage is pattern recognition supported by repeatable disciplines.
· They know which questions to ask earlier.
· They recognize the difference between ordinary transition friction and a structural constraint.
· They understand when a target's capabilities should be absorbed, when they should be preserved, and when the acquired company should be held more independently.
· They establish governance before the volume of decisions overwhelms informal channels.
· They conduct retrospectives and carry the evidence forward.
A first-time or infrequent acquirer has none of that institutional memory. Its executives may be highly capable operators, and many may have participated in transactions elsewhere, but individual experience is not the same as organizational capability. Unless the company's decision processes, leadership capacity, governance, and learning mechanisms can support the transaction, the acquisition will still depend on improvisation.
The companies most in need of an acquisition capability may therefore be the least able to infer their readiness from broad M&A success statistics:
A founder- or family-led company making its first acquisition
A middle-market company pursuing a target large relative to itself
A new chief executive beginning an acquisition-led growth strategy
A company entering an unfamiliar geography, customer segment, or business model
An infrequent acquirer whose prior deal experience resides with a few individuals
These companies do not need to imitate the infrastructure of a global serial acquirer. They do need a disciplined way to understand the degree of difficulty they are choosing and the condition of the organization expected to deliver it.
Integration risk begins before integration
Bain reports that among M&A practitioners who had experienced a failed acquisition, 83 percent identified integration as a primary problem. The statistic is often interpreted as evidence that companies need better post-close execution. That is true, but incomplete. Many integration problems begin as pre-existing organizational conditions.
A decision bottleneck does not first appear on Day One. Day One exposes it. A shallow leadership bench is not created by the integration; the transaction places more demand on it. Founder dependency in the target does not begin when the founder's transition agreement becomes difficult to execute. It was present before signing, even if diligence never made its practical consequences visible.
This is why diligence and integration should not be treated as separate disciplines divided by the closing date. They are the same organizations viewed at different moments.
Before close, leadership dependency, unclear authority, limited execution capacity, or weak escalation appear as diligence findings. After close, those same conditions become delayed decisions, missed synergies, executive overload, customer disruption, talent loss, and repeated revisions to the integration plan. The distinction is timing, not underlying cause.
From transaction experience to organizational evidence
Organizational Diligence examines whether the organizations involved can deliver what the transaction assumes. SCALE provides the evidence architecture for that work across five connected conditions: Strategic Alignment, Capability to Execute, Accountability & Governance, Leadership & Culture, and Enterprise Resilience.
The purpose is not to reduce a complex acquisition to a single readiness score or predict whether a deal will succeed. It is to identify where capacity exists, where risk is concentrated, what assumptions need to be tested, and where the transaction will place the organization under forward stress.
Used across the transaction lifecycle, the evidence has a different purpose at each stage:
The acquirer's pre-transaction reading establishes a baseline for the company that intends to buy.
The target's pre-close reading provides a reference point for understanding what is being acquired organizationally.
Integration design uses both readings to determine what should be protected, changed, combined, or left distinct.
The first post-close reading establishes the baseline for the combined company—the organization the transaction created.
Subsequent readings show whether intended conditions are improving, persisting, or drifting.
The evidence carried forward helps the acquirer recognize and prepare for similar conditions earlier in the next transaction.
The first acquisition then becomes more than a transaction. It becomes the beginning of an institutional evidence base.
What the advisors around the deal can see
This complements the work of advisors such as bankers, attorneys, accountants, tax advisors, professionals, or integration leaders by providing a common organizational frame through which their findings can be acted upon. An advisor may identify a technology dependency, an aggressive synergy assumption, an unresolved leadership obligation, or a governance issue. Organizational Diligence asks whether the acquirer has the capacity, authority, and operating discipline to address it while continuing to run the existing business.
The advisor's question therefore expands from: Is this the right target and the right transaction? to: Is this company presently capable of owning, governing, integrating, and improving what it intends to buy?
The ready acquirer
Experienced acquirers have learned that acquisition success is an organizational capability. Companies approaching their first acquisition, beginning an acquisition program, or entering a new market do not need to wait through several transactions to start developing that capability. They can begin by examining themselves with the same seriousness they bring to examining the target.
The acquisition muscle most companies have not yet built is the ability to recognize what the deal requires of the organization, prepare before the pressure arrives, measure what changes after close, and become more capable through the experience.
