Brand strategy in mergers and acquisitions

Three branding architectures: who and when chooses which

Open sources most often mention three models: the buyer absorbing the brand, a joint brand, and a flexible (geographic or product-based) architecture. In practice, the distribution looks different from theoretical schemes — data from Ogilvy-NewtonX 2024 show the real picture of the market.

It is worth separately noting a flexible strategy — geographic or product-based brand separation without complete identity merger. Renault-Nissan is not a joint brand in the sense of visual unification, but a union where each company retains its own identity in its respective markets, and synergy is achieved at the platform and procurement levels. This approach works well when brands have different geographical territories of trust and combining the names would only confuse the consumer.

To rename or to leave as is: we assess the risk, not intuition

The question of whether to rebrand or not is decided not by a marketer's taste, but by numbers. Brand Finance has recorded that in the first year after rebranding, companies lose on average 2,1% in performance, whereas non-rebranded acquisitions only lose 0,4%. Short-term, changing a brand is indeed more expensive. But the horizon matters: in the long run, it is precisely rebranded assets that show lower risk of major failure — the very 56% difference in the probability of damage.

The exception is the banking sector, where rebranding is the most expensive: losses can reach -8,9%. The reason is simple: banking relationships are local, and customer trust is tied to a specific branch name, not an abstract corporate identity. Here, changing the name often destroys what the deal was originally made for — the client base.

Practical conclusion for decision-making:

• if the brand of the acquired company is strong locally and tied to trust (banks, regional B2B, services) — keep it longer than it seems reasonable;
• if the brand is weak or reputationally toxic — switching to the buyer's brand is cheaper than trying to 'save' a dead name;
• if brand strengths are comparable and audiences overlap — consider an endorsement scheme like "Company A, part of Company B" as an intermediate step before full integration.

Why customers and employees leave: loss of authenticity, not logo change

Post-transaction attrition is rarely linked to the mere fact of ownership change. The reason is deeper — consumers react to what is called values authenticity loss: a gap between the brand's promises and how it now behaves within the new structure. Research shows that this effect is independent of the buyer's size but intensifies cumulatively — if a brand has already been resold several times, audience loyalty drops more sharply with each subsequent deal.

A telling case is Amazon and Whole Foods. The brand was formally untouched, the logo remained the same. But the implementation of metrics-driven management and the reduction of employee autonomy destroyed the culture from within: the company first fell out of Fortune's Best Companies to Work For list (where it had been for 18 consecutive years, marking the 20-year anniversary of the brand in 2017), layoffs began and attempts to form a union started. Customers and employees didn't leave because of the name — they left because of the changed experience under the old signage.

The role of the brand in the integration of cultures of two companies

Here, brand strategy works as an external signal of an internal process: what happens to identity on the facade reflects what happens to people inside. DaimlerChrysler is a case study of failure precisely along this line: insufficient cultural integration and weak communication between the German and American teams caused Chrysler's value to drop from $36 billion in 1998 to $6–7,5 billion by 2007. A joint brand on paper did not save the deal, because real convergence of management practices did not follow the visual merger.

The main challenge in brand migration is not operations (35% of companies cite it as a problem), but change management: 48% of deals struggle with it. Harvard Business School, in its research, identifies a success factor often ignored: maintaining leadership of the acquired company and continuity of the management team. When people who built the brand are given the opportunity to continue working, the cultural seam heals faster than when management is fully replaced by new faces of the acquiring company.

How to prevent brand value loss before deal closure

68% of companies address the branding issue before or during deal closure — and that is the right timing, but most of them limit themselves to choosing the architecture without checking its resilience. Brand values conflict diagnostics should become part of due diligence, not a post-deal problem solved "on a case-by-case basis".

1. Conduct an audit of values authenticity — compare public commitments of both brands and identify areas of direct conflict (for example, employee autonomy vs. performance metrics, as in the case of Whole Foods).
2. Assess the brand history: whether it has already been resold previously and with what effect on loyalty — cumulative risk needs to be built into the model separately.
3. Choose the portfolio architecture (acquirer, co-brand, retention, flexible model) based on the strength of local trust, not corporate ambitions.
4. Document three supporting decisions: the speed of migration — immediate or phased; the strategy of visual identity; the strategy of endorsement.
5. Model the short-term drop in performance (benchmark: -2,1% during rebranding versus -0,4% without it) and build it into the financial plan of the deal, not treat it as a surprise.

Such an approach shifts brand strategy from the category of 'post-deal styling' to the category of a due diligence tool — and that is exactly what distinguishes deals that preserve value from those that lose it in the first year of integration.
