Payment fraud prevention technology firm, Retail Decisions, is set to change hands for £120m.
Private equity group Palamon will sell ReD, as the e-commerce tech firm is known, to ACI Worldwide after first acquiring it in 2006.
Retail Decisions claims to screen a quarter of all US e-commerce transactions and is used by companies in Europe, Latin America and Asia as well.
Its products include ReD Fraud Xchange, an online platform that enables merchants and card issuers to perform real-time checks to tackle payment fraud, as well as ReDi, a business intelligence tool to analyse transactions.
Paul Stanley, CEO at ReD, said: "We have thoroughly enjoyed working with Palamon and are proud of the results we have achieved together. Their understanding of the e-commerce space combined with their experience in payments and enterprise software was invaluable in establishing ReD as a global leader in fraud prevention.
"Significant investments in new products and sales channels have further strengthened our global platform and we are well placed to continue delivering strong growth. We look forward to working with ACI Worldwide in the next phase of our development."
Palamon is expected to see returns of up to 2.5 times what it invested in the company.
