Finastra could be sold or merged with another company as its owner Vista Equity Partners reviews its options.
Morgan Stanley is advising on the early-stage review, Reuters reported, citing four people with knowledge of the discussions.
Vista created Finastra in 2017 by combining Misys and Canada’s D+H. The London-based company supplies payments, lending and other banking software to more than 7,000 financial institutions.
The firm has sold or agreed to sell several business units since Chris Walters became CEO in January 2025.
CORA Group acquired its US mid-market banking business in June, while its former treasury and capital markets division now operates as Teciem under Apax Partners.
That same month, Finastra agreed to sell its Universal Banking business to Pollen Street Capital.
Vista may also divest only part of its stake, while Finastra could pursue an acquisition of its own.
Sources cited by Reuters placed Finastra’s value above the high-single-digit billions, with one estimating that it could reach US$12 billion.
The latter estimate was based partly on projected earnings before interest, tax, depreciation and amortisation of US$650 million this year.
The report also identified Blackstone as a prospective buyer and said other investment firms had shown early interest.
The review may not lead to a deal. Vista, Finastra, Morgan Stanley and Blackstone declined to comment.
