Payments company Stripe and private equity firm Advent International have made a joint offer to acquire PayPal Holdings Inc for $60.50 per share, in a deal that would value the payments ‌company at ⁠more ⁠than $53 billion, two people familiar with the matter said.

The ​offer, submitted earlier this month, is backed by about $50 ​billion in committed financing from banks, the people said, and represents around a 28% premium ​to PayPal's closing share ⁠price on ‌Tuesday.

The people declined to be ​named as ​the deal discussions are confidential. ⁠Advent declined to comment, while PayPal and ​Stripe did not immediately respond to ​requests for comment.

The proposal follows an initial approach made in early April, the sources said. Stripe and Advent have not received a response from PayPal and are ‌seeking to reach an agreement by the end of the month, the ​sources added.

Under ​the proposal, ⁠Stripe and Advent would jointly own PayPal, with each holding an equal stake, rather than breaking up ​the company, the people said. There is no certainty the approach will result in a transaction, they added.
