Reputation Risk in M&A – How Hidden Perceptions Can Derail a Deal

Reputation – The Risk You Can’t See on a Balance Sheet

Financial reports may present a clear picture of revenue, assets, and profitability, but they reveal very little about a company’s reputation. In mergers and acquisitions, however, reputational risk can be a dealmaker or a dealbreaker.

Reputation risk in mergers and acquisitions is shaped by perception. It sits in the spaces financial data cannot reach, including leadership credibility, customer sentiment, online reviews, ESG performance, and employee morale. These signals are not always visible, but they are increasingly influencing how buyers assess risk and long-term value.

As scrutiny during due diligence intensifies, reputational concerns are no longer peripheral. They are central to decision making.

Left unchecked, these hidden perceptions can:

• Stall due diligence
• Reduce buyer confidence
• Trigger post sale instability
• Lower the offer or halt the deal entirely

In a market where buyers are looking beyond the balance sheet, reputation has become one of the most critical and least visible drivers of deal outcomes.

Real-World Examples of Reputation Risk in Mergers & Acquisitions

• Facebook’s acquisition of Giphy was later blocked by UK regulators due to antitrust and data governance concerns, reflecting reputational and ethical risk.

• BP’s acquisition of ARCO in the 1990s was heavily scrutinised due to environmental controversies, proving that ESG perception can influence deal terms.

• Small-to-mid-market deals are also affected: We’ve seen prospective acquirers walk away due to a pattern of negative employee reviews or social media backlash against senior leadership.

As PwC notes in its Global M&A Trends report that reputation is a growing factor in buyer diligence, with brand perception, leadership culture, and stakeholder trust under increasing scrutiny.

Common Reputation Risks in M&A

Risk Area	Example
Leadership Perception	Founder with poor public image or aggressive leadership style
Employee Sentiment	Negative Glassdoor reviews or internal morale issues
Customer Reputation	Poor service reviews, low retention, or online complaints
Governance Concerns	History of compliance failures or unethical supplier relationships
ESG exposure	Greenwashing allegations, lack of net zero plan, or weak DEI performance
Media scrutiny	Past PR crises or sensitive associations (e.g. political affiliations)

How to Identify and Assess Reputation Risk

Before you go to market, conduct a reputation audit that includes:

1. Stakeholder perception research: Interview or survey customers, employees, and suppliers to uncover common themes.
2. Online reputation audit: Review ratings, social sentiment, media coverage, and search results.
3. ESG and governance gap analysis: Use frameworks like B Corp or ISO 26000 to identify where your values and performance may fall short.
4. Leadership brand audit: Review public-facing statements, visibility, and alignment with company values.
5. Crisis mapping: Catalogue any past PR or compliance issues and document how they were handled.

How to Mitigate and Prepare

Package the positives:  Don’t just fix problems, rather highlight your strengths. Showcase customer loyalty, community involvement, staff advocacy, or B Corp certification.

Control the narrative: Prepare transparent talking points on any reputational issues so buyers hear your version, not just their own interpretation.

Include brand and reputation metrics in your data room:  NPS scores, retention rates, sentiment trends, and employee survey highlights add credibility.

Nominate reputation stewards:  Identify internal leaders who can speak to culture, ethics, and brand integrity during buyer discussions.

Mackman’s Perspective: Reputation as a Strategic Asset

At Mackman, we do not view reputation as a soft or secondary concern. It is a strategic multiplier, directly influencing brand equity, customer retention, and trust in leadership.

In the context of mergers and acquisitions, this becomes particularly important. A clear and honest understanding of how your organisation is perceived allows you to enter negotiations with greater confidence. It provides the clarity needed to anticipate concerns, address vulnerabilities, and reinforce the strengths that underpin long-term value.

Our role is to bring that clarity into focus. By working closely with our clients, we help uncover the perceptions that sit beneath the surface and shape how a business is evaluated.

This includes exploring stakeholder perspectives through research and brand audits, identifying potential reputational risks before they become barriers, and ensuring that messaging is aligned with both organisational values and demonstrable evidence.

The result is a more coherent, credible, and resilient position, enabling organisations to protect and project trust throughout the deal lifecycle.
