Inter Pag deal puts ACI Worldwide in focus for Brazil’s digital payments growth

ACI Worldwide (ACIW) is back on investor radar after Inter Pag selected the ACI Acquiring Platform and RS2 powered back-office card management for its next phase of payments expansion in Brazil.

The agreement ties ACI Worldwide more closely to one of Brazil’s large small business focused acquirers, at a time when Pix and other alternative methods are reshaping how local merchants accept and process payments.

The Inter Pag win lands as ACI Worldwide’s 90 day share price return of 23.75% and year to date share price return of 14.76% sit alongside a 3 year total shareholder return of 121.51%. This hints that momentum has been building over time despite a softer 30 day share price return of 6.93%.
