Payments-software provider ACI Worldwide Inc. is in talks with private equity firms about a potential sale, according to people familiar with the matter.

The Naples, Florida-based company is working with financial advisers as it fields takeover interest, said the people, who asked to not be identified because the matter isn’t public. There’s no certainty ACI will reach a deal given the rocky state of the leveraged financing markets, one of the people said.

A representative for ACI declined to comment.

The company has long been viewed as ripe for a takeover because it’s a relatively small player in an industry that’s been consolidating for years.

ACI tapped an adviser to explore a sale two years ago, Barrons reported, after Starboard Value took a stake in the company and pushed it to sell. Starboard has been selling down its stake since reaching an agreement in 2021 that added two independent directors to ACI’s board.

ACI offers a range payments services to banks, merchants and other customers, including a platform for handling in-store transactions and fraud-detection services, according to its website.
