CGI commissioned Oxford Economics to develop an analytical methodology to examine share-price movements in companies that had experienced publicly disclosed cyber breaches.

  • The average impact on company valuation was a drop of 1.8% in share price following a cyber incident
  • For the average FTSE 100 company, this represents a drop in value of some £120 million
  • Two-thirds of companies share prices were adversely affected by a cyber incident
  • In some more extreme cases, share price reductions of up to 15% were observed

We hope this connection will resonate with business leaders and contribute to building more mature security business cases.

Our infographic presents the facts and figures of the report.
