Corporate reputation accounts for 28% of the S&P 500’s total market capitalisation in the US, equating to $11.9 trillion in value. In the UK, reputation-driven value contributes £719 billion, or 30% of the FTSE 350.

While a strong reputation can propel market value to new heights, a damaged one can unravel billions overnight.

Why does reputation drive so much value? 

Trust. 63% of global investors call it a critical factor in their decisions. Companies with high trust tend to outperform peers on total shareholder returns and enjoy a lower cost of equity capital. A damaged reputation works in reverse.

What does a reputation crisis cost?

The losses can be steep and fast. One US study put the average brand value lost to a data breach at $184 million to more than $330 million. Qantas saw its brand value fall from $3.1 billion to $2.7 billion after a loss of community and customer trust. Following tax evasion allegations against its Managing Director, MinRes’ share value dropped 9.6%.

Do companies with strong reputations recover faster?

Yes. They recover five times faster from reputation issues, thanks to a buffer of stakeholder goodwill built before the crisis.

How can companies protect their reputation?

  • Transparency is non-negotiable: Address issues head-on, share updates proactively and explain the reasoning behind key decisions.
  • Ethical practices foster trust: Set a code of ethics and back it with measurable action, such as impact reporting or ethical supply chain initiatives.
  • Governance strengthens resilience: Build accountability and risk-identification systems that catch issues before they escalate, as Australian banks did after the Royal Commission.
  • Proactive communication prevents escalation: Define spokespeople, set an internal communication chain and use social listening to respond before concerns spiral.
