The Unresolved Decisions: How M&A Value Gaps Emerge and How to Bridge Them

Michael Pokorski, Rupinder Gill, and Kevin Desai, leading figures in the Deals practice at PricewaterhouseCoopers LLP, have highlighted a critical challenge in mergers and acquisitions (M&A): the persistent value gap that emerges when leaders fail to address the fundamental operating implications of a deal thesis. Their insights, drawn from a comprehensive PwC memorandum and the firm’s 2026 M&A Integration Survey, reveal that while companies are increasingly making larger, more strategic bets through M&A, a significant portion are failing to fully realize the intended value due to a failure in translating strategic intent into concrete operational decisions.

The core of the problem, as identified by PwC, lies in what they term the "decision gap." This gap represents the chasm between the high-level strategic rationale of a deal—the "thesis"—and the explicit, actionable choices required to make that thesis a reality within the combined entity. This disconnect often arises when critical decisions are deferred, remain implicit, or are never translated into funded actions with measurable value commitments.

The Evolving M&A Landscape and the Escalating Stakes

The current M&A environment is characterized by a confluence of factors that elevate the importance of successful integration. Deal volumes have remained relatively flat or have declined, a trend exacerbated by persistent geopolitical instability, economic uncertainty, and fluctuating interest rates. Despite these headwinds, aggregate deal values have reached record highs. This suggests that the companies continuing to engage in M&A are often well-capitalized organizations making substantial investments to drive growth, enhance margins, acquire new capabilities, leverage advanced technology, or bolster their strategic market position.

This shift in the nature of M&A transactions has direct implications for post-deal integration. Large-scale acquisitions can no longer be treated as mere post-close administrative exercises focused on connecting IT systems, completing Day One tasks, and stabilizing operations. While these foundational activities remain necessary, they are insufficient to capture the full value proposition of a significant deal. The integration plan must actively drive the operating decisions that transform the strategic promise of the merger or acquisition into tangible competitive advantages and superior financial performance for the combined company.

The PwC 2026 M&A Integration Survey: Uncovering the Performance Gap

The findings of PwC’s 2026 M&A Integration Survey, which surveyed executives involved in M&A transactions within the past three years at organizations with annual revenues exceeding $1 billion, underscore this challenge. The survey’s primary observation is a stark reality: only approximately one in three acquirers fully achieve all their prioritized deal thesis objectives. This statistic does not imply a lack of strategic ambition or poor deal selection by the majority of companies. Instead, it points to a systemic issue in how the strategic intent of a deal is translated into operational reality.

The survey’s data reveals that the performance gap widens precisely at the juncture where the deal thesis must inform the combined company’s customer engagement, product development, organizational structure, and key performance indicators. This distance—between the abstract strategic vision and the concrete choices needed for execution—is the decision gap.

The Decision Gap: A Critical Obstacle to Value Realization

The concept of the decision gap is central to understanding why many M&A deals fall short of their intended outcomes. Traditionally, integration has been viewed as an execution phase that follows the design of the deal. However, the most successful acquirers adopt a different approach. Prior to the official close of the transaction (Day One), they make crucial decisions regarding what needs to change, what must be preserved, what elements should be integrated, and what aspects can be phased in over time. This proactive approach effectively defines the target operating model for the combined entity, ensuring it is structured to deliver the value that justified the deal in the first place.

Too often, acquirers bypass this critical step, moving directly from the deal thesis to the integration plan and treating the target operating model as an emergent outcome of the execution process. This skipped step represents a significant leakage of potential value. It is in this phase that the few critical decisions are made—or, crucially, not made—that determine how the combined company will operate to fulfill the deal’s promise and safeguard the unique attributes that made the target acquisition so valuable.

The CEO’s Crucial Question

As PwC suggests, leaders should be asking: "What are the three or four changes this deal requires, and which decisions become harder and more expensive if we defer them past Day One?" This frames the integration challenge not as a broad overhaul, but as a focused effort on a select number of high-impact decisions.

Persistence of the Pattern Amidst Rising Stakes

The persistent nature of this challenge, even as M&A stakes have increased, is a significant concern. Historical comparisons reveal a lack of substantial improvement in pre-deal planning for target operating models. In 2020, 61% of acquirers reported having a target operating model in place at signing, a figure that saw only a marginal two-percentage-point increase by 2023. The 2026 survey indicates that successful acquirers lead their less successful counterparts by a considerable margin—between 13 and 27 percentage points—in defining core elements of the target operating model before closing. This suggests that while M&A frameworks and methodologies abound, the critical task of moving key decisions upstream has remained a persistent struggle.

The Talent Paradox: Acknowledged Importance, Underestimated Action

The people aspect of M&A integration also reveals a similar disconnect. In 2017, seven in ten acquirers identified talent as a top deal objective. Yet, in the current survey, only 16% of respondents reported assessing leadership and talent prior to signing or conducting thorough people and organizational diligence. While leaders consistently emphasize the importance of talent, decisions surrounding talent selection, leadership appointments, and organizational design often do not receive the same level of attention as those related to technology, finance, or commercial strategy. This oversight can have profound implications for the success of the integration and the realization of value.

The Value Gap is Fundamentally a Decision Gap

While common explanations for M&A failures often cite overly optimistic deal theses, poor integration management, or organizational resistance to change, the PwC survey points to a more actionable pattern rooted in decision-making. The performance gap begins earlier in the process, specifically when leaders determine whether the deal’s strategic thesis will actively shape the combined company’s day-to-day operations.

The survey findings indicate that while both successful and less successful acquirers utilize similar value creation themes—such as market expansion, strategic capability acquisition, operating efficiency, or revenue acceleration—a divergence in success emerges when these themes are not translated into a concrete plan that resolves the few critical choices that underpin the value case.

Crucially, successful acquirers are significantly more likely to define thesis-relevant operating model elements before the deal closes, across all identified deal themes. The most pronounced difference is observed in revenue-acceleration transactions, where 71% of successful acquirers defined relevant operating model elements pre-close, compared to only 44% of limited-success acquirers. This substantial 27-percentage-point gap is not an abstract theoretical issue; it represents the difference between entering Day One with clear decisions on customer ownership, pricing strategies, distribution channels, incentive structures, and product priorities, or facing two commercial organizations attempting to resolve these complex issues amidst a dynamic market.

The Target Operating Model: A Set of Decisions, Not a Redesign Exercise

The term "Target Operating Model" can sometimes evoke the image of a comprehensive, long-term redesign project. However, PwC’s perspective is more pragmatic. Not every acquisition necessitates a complete overhaul of the buyer’s existing operating model. What is essential, however, is a deliberate and explicit decision-making process to identify and implement the specific changes required to deliver the deal’s thesis.

For one deal, this might mean merging two sales forces. For another, it could involve preserving the target company’s product and engineering structure while integrating finance, data governance, and select IT infrastructure. The leadership team’s responsibility is to identify, and then make, the three to four critical choices that will protect growth, preserve the acquired capabilities, and establish clear accountability for value creation.

This practical approach to operating model decisions is integral to an effective integration strategy and plan. The specific choices are dictated by the unique deal thesis, with the project plan serving as the mechanism for their execution post-decision.

Consider, for instance, a large consumer packaged goods company acquiring an adjacent product line in a burgeoning market. Translating the deal thesis into key decisions could involve:

• Defining customer ownership: Deciding which sales force or channel will be responsible for serving customers of the acquired product line to avoid confusion and ensure continued customer satisfaction.
• Establishing pricing and promotional strategies: Aligning pricing models and promotional activities to maximize revenue and market penetration without cannibalizing existing product sales or devaluing the acquired brand.
• Integrating or separating supply chains: Determining the most efficient and cost-effective way to manage the supply chain for the acquired products, considering factors like existing supplier relationships, manufacturing capabilities, and distribution networks.
• Aligning product roadmaps: Deciding how the product development pipelines of both entities will be integrated or managed to foster innovation and leverage synergies.

Highly effective dealmakers make these crucial design decisions early and communicate them widely, fostering clarity and focus. This allows the integration efforts to concentrate solely on activities that actively bring the deal thesis to life.

A structured framework for these decisions can involve separating them into four key actions:

1. Change what creates the intended synergy: Identify and implement the specific operational changes that will unlock the projected value.
2. Protect what made the target valuable: Safeguard the core assets, capabilities, and customer relationships that were the primary drivers for the acquisition.
3. Integrate the capabilities and operations that should come together: Determine which functions and systems will benefit from consolidation for efficiency or strategic advantage.
4. Sequence what needs more evidence: Prioritize decisions based on their impact, reversibility, and the need for further data or market validation after the close. This sequencing judgment is critical to avoid premature decisions that could destroy value or miss opportunities.

This framework prevents the integration process from treating all unresolved issues with the same level of urgency, allowing for a more strategic and efficient allocation of resources.

Tailoring Integration Architecture to the Deal Thesis

Most M&A transactions involve multiple value objectives. Respondents in the PwC survey typically identified around two primary deal themes per transaction, most commonly market expansion and strategic capability acquisition. This diversity underscores a critical point: a single, standardized integration template is insufficient to guide leaders on prioritization. The integration architecture must be directly determined by the deal thesis.

Thesis-Specific Decisions Drive Integration

A market-expansion deal is not simply an efficiency-focused integration with a geographic component. Similarly, a strategic capability acquisition is not a standard functional integration. Each type of deal carries a distinct model for success and requires a unique set of early decisions.

The Permanent Cost of Delayed Decisions

A delayed decision is far more than a simple postponement. It can result in the loss of valuable customers, the departure of key talent, duplicated investments, protracted synergy capture, and a period where the combined company operates at a performance level below that of either of its legacy entities. While momentum may eventually be regained, the value lost during the delay is often irretrievable.

The Execution System: Proving the Value Hypothesis

A value driver, by its nature, remains a hypothesis until it is transformed into a tangible initiative. This transformation requires more than analytical insight; it demands a management commitment. This commitment translates the hypothesis into an initiative with a designated owner, a defined timeline, clearly articulated dependencies, allocated funding, and a measurable outcome that can be validated by the finance department. Identifying synergy opportunities is not merely an analytical exercise; it is a strategic choice about how the company will operate, who will be accountable, what resources will be provided, and how success will be evaluated.

The survey results indicate a significant shortfall in this area: only 46% of all respondents reported that value drivers were fully translated into executable initiatives with clear owners, timelines, and dependencies before integration commenced. This figure rises to 59% among successful acquirers but plummets to 28% among limited-success acquirers. This substantial 31-percentage-point gap serves as compelling evidence that value creation is less dependent on the initial quality of the synergy case and more on the robustness of the execution system designed to realize that value.

Governance Design: A Pre-Day One Imperative

A robust value governance system is essential to connect the deal thesis to a prioritized list of value drivers, and then link each priority to a named owner possessing the requisite funding, authority, and a defined method for proving the outcome. The integration management office (IMO) plays a crucial role within this system, but the ultimate ownership of decisions and trade-offs rests with the CEO and the executive team.

The following governance questions are critical to address before Day One:

• What is the value priority? Clearly name the two or three most critical outcomes and define how they interact.
• Who is accountable? Designate an executive sponsor and an initiative owner with the necessary authority, funding, and escalation rights.
• What has to happen first? Document all dependencies, key milestones, critical decisions, and potential roadblocks that could impede delivery.
• How will value be proven? Establish baseline metrics, controls, validation rules, and a reporting cadence that clearly distinguishes realized value from forecasts and normal business performance.
• How will incentives work? Align incentives directly with validated outcomes, not merely with reported activities or unproven forecasts.

Measurement: Beyond a Reporting Afterthought

Measurement is the second critical component of this governance system. While three-quarters of respondents tie direct and material incentives to synergy outcomes, fewer than half express strong confidence that reported synergies accurately reflect real, auditable value. Among successful acquirers, 62% meet this standard, compared to only 27% of limited-success acquirers. Incentives should reinforce validated outcomes; they cannot serve as a substitute for rigorous validation.

This "confidence gap" has significant implications for CEOs, CFOs, boards of directors, and investors. A finance-validated value system empowers leaders to differentiate between realized value and forecasted value, accounting treatments, double-counting, and ordinary business performance. It also enables management to make timely adjustments to the integration strategy while there is still sufficient opportunity to protect the deal thesis. A strong measurement capability provides the visibility necessary to establish a credible incentive structure directly linked to the right outcomes.

However, the strength of any incentive structure is directly proportional to the evidence supporting it. Proving value extends beyond simply reporting that an initiative is complete. Leaders must be able to demonstrate what has changed, against what baseline, who owns the resulting outcome, when that value has impacted the income statement or cash flow, and what evidence supports its attribution to the deal. Without such standards, organizations risk rewarding activity rather than demonstrating that the deal has created incremental, verifiable value.

The most effective governance model integrates the deal thesis, the portfolio of initiatives, the critical operating decisions, the financial baseline, and the incentive design. This unified approach provides CEOs and CFOs with a clear, shared understanding of where value is being captured, where it is at risk, and which unresolved decisions require executive escalation.

Enablers: Integral to the Value Architecture

Talent, technology (including AI), tax, and regulatory strategy are critical enablers that become material when the deal thesis depends on them. The survey findings highlight that their impact is maximized when leaders address the relevant decisions early, rather than treating them as specialized workstreams to be handled post-close.

These four enablers are emphasized because they repeatedly determine whether the deal thesis can be executed with the promised speed, economic efficiency, and level of confidence. They are not necessarily universal pillars for every integration, nor do they represent an exhaustive list. Commercial ownership, supply chain management, customer experience, and other capabilities should be incorporated into the architecture whenever the deal’s success hinges upon them.

People: Defining Dependence and Ownership

The critical question regarding people is not solely about the level of investment in talent. It is about identifying which leaders, roles, capabilities, and behaviors are essential for the deal’s success, determining who will lead these areas, and what must be protected before any organizational restructuring or talent reallocation begins.

The survey results identify clear organization design and decision rights as the leading people-related challenge, cited by 56% of respondents. Culture alignment and the management of people-related change follow closely at 52%. These are fundamental operating model choices that dictate decision-making authority, leadership collaboration, and the organization’s collective understanding of the combined company’s future identity.

Acquirers that successfully translated the deal thesis into concrete leadership, talent, and organizational actions reported higher rates of complete success in achieving revenue synergy outcomes (55%) compared to those that did not (34%). Among successful deal cohorts, this difference widens to 62% versus 29%. While the survey relies on self-reported data and does not establish direct causation, the strong pattern supports a practical conclusion: talent strategy requires the same deliberate discipline as other core operating strategy decisions.

Data and Technology: Building for the Thesis

Leaders must assess how systems, data, and technology will either accelerate or impede the path to full-potential value realization. This assessment should guide decisions on which platforms will support the combined company, how data will be owned and governed, and which architectural choices are most critical for customer experience, operational resilience, cost efficiency, and speed. The deal thesis should dictate which elements need to be integrated or protected early, and which can be sequenced, maintained separately, or deferred to later stages of the integration.

Technology and data were instrumental in enabling at least a quarter of synergies for nearly nine in ten acquirers, and more than half of synergies for almost a third. Access to new technologies was a significant transaction objective for 78% of respondents, an increase from 72% in PwC’s 2023 M&A Integration Survey. Among successful acquirers, this figure rises to 84%. These findings reinforce that systems, data, and technology are integral components of the deal’s value architecture; they can enable the thesis, constrain it, or materially alter the speed and economics of value capture. Consequently, these technology decisions must be designed around the value case, encompassing what must be integrated, protected, or kept separate.

Artificial Intelligence: Distinguishing Value Questions

Within the broader technology and data architecture, leaders must also be explicit about the role AI is expected to play in achieving the deal’s value case. Depending on the specific transaction, AI and other advanced technologies can serve various functions, from accelerating integration processes to unlocking entirely new opportunities. Each scenario necessitates distinct decision-making.

The survey results highlight the need for this distinction. Approximately three-quarters of acquirers utilize AI in some aspect of their integration process, yet only one in five identified building an AI-ready foundation as a primary integration objective. Among successful acquirers, this proportion rises to roughly one in four, while among limited-success acquirers, it is closer to one in eight. This implies not that every deal requires an AI transformation, but rather that leaders must explicitly determine where AI contributes to the value thesis and subsequently build the necessary data, technology, governance, and talent foundations accordingly. The finding does not suggest that AI is an automatic source of value in every deal; rather, it emphasizes that the value proposition of AI must be clearly articulated rather than subsumed within generic claims about adoption.

Tax: Value Creation from Pre-Close to Post-Close

Tax considerations extend beyond post-close operating model design. Prior to the deal’s close, tax diligence can identify inherited risks, and acquisition structuring can help preserve or maximize valuable tax attributes. Post-close, legal entity structure, supply chain design, transfer pricing policies, intellectual property ownership, incentive arrangements, indirect taxes, and ongoing compliance efforts collectively shape the economic landscape of the combined company.

Successful acquirers were more likely to report that tax strategy meaningfully contributed to financial returns, with 61% reporting this compared to 35% among limited-success acquirers. These findings underscore the importance of including tax expertise in structural decision-making processes, and that tax-related work cannot be considered complete upon the transaction’s closing.

Regulatory Strategy: Safeguarding Deal Certainty

Regulatory strategy is typically viewed as a discipline focused on value protection and deal certainty rather than a direct lever for value creation. In the survey, three in four deals required six months or more for regulatory clearance, and more than one in three took nine months or longer. The practical decision for leaders is whether to proactively develop the competition narrative, gather relevant data, consider remedy scenarios, and understand the operating implications before the regulatory process commences, thereby avoiding reactive choices under pressure.

Successful acquirers were 12 percentage points more likely to define core antitrust narratives during the diligence phase and utilized structured regulatory scenario planning at 1.25 times the rate of their peers. Where regulatory risk is material, early scenario planning can preserve optionality, reduce execution uncertainty, and safeguard the deal’s value proposition as the approval process unfolds.

A CEO Agenda for the Next Integration

The integration agenda for leadership should be deliberately focused, not on a project checklist, but on answering a core set of questions before the integration plan devolves into a collection of disparate workstreams.

The key questions leadership should address include:

• What is the unequivocal thesis of this deal? What is the singular strategic imperative that drives this transaction?
• What are the three to four most critical changes required to realize this thesis? Focus on the decisions that will have the most significant impact on value creation.
• Which of these changes become harder and more expensive if deferred past Day One? Identify the decisions that carry a time penalty or risk significant value erosion if delayed.
• Who is accountable for each of these critical changes? Assign clear ownership and empower individuals to drive these decisions.
• How will we measure success and prove value? Define clear metrics and validation processes to track progress and confirm value realization.

The ultimate test for leadership is whether they can confidently name the few changes that matter most and, crucially, assign owners and establish mechanisms to prove the resulting value. If these conditions are not met, the deal thesis remains merely a hypothesis.

Conclusion: Architecting the Company the Deal Was Meant to Create

The findings of the PwC survey do not propose a universal integration formula. Instead, they advocate for a disciplined approach. The most successful acquirers do not rely on the integration team to passively discover the right answers post-close. They proactively identify the decisions that are intrinsically linked to the deal thesis, make the most critical ones early, and establish clear accountability and robust measurement frameworks around them.

The companies that will ultimately achieve the greatest success in M&A will be those that make the pivotal choices dictated by their deal thesis, translate those choices into concrete, owned commitments, and rigorously prove the resulting value. This foundational work must commence well before Day One, requiring leaders to actively architect the company that the deal was strategically intended to create.

About This Survey

PwC’s 2026 M&A Integration Survey gathered insights from 530 C-suite executives and senior dealmakers across six key industries: consumer markets; energy, utilities, and industrials; financial services; health industries; industrial products; and technology, media, and telecommunications. Respondents shared firsthand knowledge of merger or acquisition transactions in which they were involved within the preceding three years.

"Successful acquirers" are defined as respondents who reported complete success in achieving all identified deal thesis objectives. "Partial-success" and "limited-success" acquirers achieved some, or limited/no, prioritized objectives, respectively. The survey findings are based on respondent-reported outcomes and should be interpreted as associations rather than definitive causal estimates. All percentages presented in this report are derived from the PwC M&A Integration Survey 2026, unless otherwise specified.
