Mergers and acquisitions can destroy brand value long before a new name or logo is considered. Decisions made during due diligence and integration can affect customer loyalty, pricing power, reputation, employee alignment and future growth. Companies can protect that value by assessing brand equity before close, understanding the economic role of brand assets, and defining the positioning and architecture of the combined enterprise before making identity decisions.
In brief: Brand should be treated as a deal variable, not a post-close marketing exercise.
The Cautionary Tale That Still Applies
When Kraft and Heinz merged in 2015, the deal appeared compelling on paper. The combination promised scale, cost efficiencies and powerful household brands. But the subsequent history illustrates how quickly intangible value can erode when growth, relevance and brand investment fail to keep pace.
In 2019, Kraft Heinz disclosed $15.4 billion in impairment charges related to goodwill and intangible assets, primarily including the Kraft and Oscar Mayer trademarks. The story did not end there. In the second quarter of 2026, the company recorded another $4.9 billion in non-cash intangible-asset impairment losses, including $3.4 billion related to Kraft, $660 million to Oscar Mayer and $445 million to Lunchables.
Kraft Heinz is an unusually visible example, but the broader lesson applies across M&A: closing a transaction does not secure the value assumed in the deal. That value still has to survive integration.
The Brand Belongs in the Deal Model
Global M&A deal value reached $4.7 trillion in 2025, up 43 percent from the prior year, according to McKinsey. At the same time, KPMG’s analysis of more than 3,000 public-to-public acquisitions over $100 million found that 57.2 percent of acquirers ultimately destroyed shareholder value. Acquirers generated an average 13.2 percent in total shareholder return above the relevant S&P sector index leading up to closing, but TSR declined an average 7.4 percent in the two years that followed.
The implication is important: the question is not simply whether a deal closes successfully. It is whether the value assumed in the deal model survives the decisions that follow.
Yet brand is often absent from the deal model. Financial, legal, operational and technology diligence receive rigorous attention, while brand questions are deferred until integration is underway. By then, decisions affecting customer perception, market positioning, portfolio structure and brand investment may already have been made.
That omission matters because so much enterprise value is intangible. Brand Finance estimates that intangible assets held by the world’s largest companies reached $97.6 trillion in 2025, up 23 percent in one year. In the U.S., intangible value represents 78 percent of market value. Brands are one component of that value, alongside technology, data, intellectual property, relationships, and other assets, but they are among the assets most directly affected by post-deal decisions.
How Does M&A Destroy Brand Value?
Brands do far more than identify companies and products. They signal value, create trust, support preference and pricing power, and help customers understand why one organization matters relative to another. During M&A, that accumulated equity can be preserved, transferred, strengthened—or inadvertently destroyed.
A Journal of Marketing study spanning ten studies, multiple research methods, product categories and brands found that acquisitions can reduce brand choice and purchase likelihood when consumers perceive the acquired brand as having compromised its authentic values. The effect varied with factors including brand age, leadership continuity, and alignment between the acquiring and acquired brands.
In our experience, three decisions create disproportionate risk.
Mistake 1: Treating Brand as a Post-Close Decision Instead of a Deal Variable
When should brand strategy be considered in an M&A transaction?
During due diligence—not after close. By the time a transaction closes, the purchase price has been set, the integration timeline established, and an initial narrative delivered to customers, employees and investors. Decisions that influence brand value are already underway.
Brand diligence should therefore address questions that have direct implications for the economics and future strategy of the deal:
- What brand equity is the buyer actually acquiring?
- Where does that equity reside—in the corporate brand, product brands, customer relationships, reputation or specific offerings?
- Which brand has the greatest permission to represent the future enterprise?
- Would retaining, endorsing, migrating or retiring an acquired brand create or destroy value?
- Does the combined business require a new enterprise brand or positioning?
BrandingBusiness developed the Brand Performance Platform™ to evaluate corporate brands from the buyer’s perspective and bring customer and market evidence into these decisions. The objective is not to turn brand into an accounting exercise. It is to make brand equity visible before decisions are made that may diminish it.
Mistake 2: Cutting Brand Assets Without Understanding Their Economic Function
How can integration decisions unintentionally destroy brand value?
After a merger, teams naturally look for duplication. Websites, product brands, marketing programs, sales materials, customer experiences and other assets can appear redundant when viewed through a cost lens. Eliminating them may produce immediate savings while quietly weakening demand, retention or pricing power.
The problem is that the economic contribution of brand assets is rarely visible in the same way as operating costs. A brand may shorten a sales cycle, reduce perceived risk, improve conversion, support a premium, retain customers or give an acquired company credibility in a market where the buyer has little presence.
Before cutting, leadership should map the function of important brand assets against four sources of value:
- Revenue and customer acquisition
- Retention and loyalty
- Pricing power and differentiation
- Efficiency, including reduced sales friction or service costs
This requires evidence rather than intuition. Customer research, journey analysis, win/loss data, behavioral data, and brand-equity measurement can help distinguish genuine redundancy from assets that are still creating value.
Mistake 3: Focusing Integration on Identity Instead of Meaning
Should a company rebrand immediately after a merger?
Not necessarily. Names, logos and visual systems are tangible, so they can create a visible sense of integration and progress. But identity is the expression of a brand, not the source of its value. The more fundamental question is what the combined enterprise should mean to customers and why it will matter more than either organization did independently.
Companies that move too quickly to identity can create hybrid brands, diluted positioning and unnecessary confusion. The Journal of Marketing research cited earlier is instructive: consumer response to an acquisition is affected by the perceived alignment between the values of the acquiring and acquired brands. A visual solution cannot compensate for a strategic contradiction.
Before making naming or identity decisions, leadership should define how the combined company will compete, what customers value in each legacy organization, which equities should be preserved, and what new promise the combination makes possible. Brand architecture should then clarify the roles and relationships among the enterprise, legacy brands, products and services.
Five Questions for Brand Due Diligence
- What brand equity are we actually acquiring? Measure awareness, preference, loyalty, reputation, differentiation, and other sources of customer value.
- Where does that equity reside? Determine whether value sits primarily in the corporate brand, product brands, specific capabilities, customer relationships, or market reputation.
- Which brand has permission to lead the combined enterprise? Evaluate customer relevance, geographic strength, strategic fit and permission to stretch—not simply company size or revenue.
- What revenue depends on maintaining existing brand signals? Identify the brands, experiences, channels, and investments supporting acquisition, retention, cross-sell and pricing.
- What should change—and what must be protected? Determine whether the right path is preservation, endorsement, migration, consolidation, or creation of a new enterprise brand.
Protect Brand Value Before, During and After the Deal
Before close, include brand equity in due diligence, evaluate brand strength from the customer’s perspective, and identify how brand decisions could affect the strategic and economic assumptions behind the transaction.
During integration, understand the economic function of brand assets before eliminating them. Resolve positioning, values, and brand architecture before rushing to naming and visual identity. Give customers and employees a clear explanation of what the combination makes possible.
After close, continue measuring brand health, customer response, and market relevance. Integration is not a one-time communications event. Brand architecture and investment should evolve as the business itself becomes more integrated.
The Question Every Deal Team Should Ask
If brand does not appear in the deal model, the model itself may be incomplete. Customers do not experience synergy targets or integration workstreams. They experience whether the company remains relevant, differentiated and worthy of trust.
The essential question for every board and leadership team considering a transaction is therefore simple: Do we understand what brand value we are buying, where it resides, and what decisions will protect or strengthen it?
When the answer is clear before the deal closes, brand becomes more than something to manage during integration. It becomes a lever for carrying the strategic value of the transaction forward.
