Visa Inc. V, +0.81% said late Monday it has agreed to buy fintech company Plaid for $5.3 billion. Plaid is the underlying technology connecting popular payment, investing and budgeting apps such as Acorns and Venmo and with consumers’ bank accounts. “We are extremely excited about our acquisition of Plaid and how it enhances the growth trajectory of our business,” Chief Executive Al Kelly said in a statement. “Plaid is a leader in the fast growing fintech world with best-in-class capabilities and talent.” The deal is subject to closing conditions, including regulatory approvals, and Visa said it expects it to close in three to six months. Visa will pay for the deal with cash on hand and “debt issuance at the appropriate time,” the credit card company said. The deal has no impact on Visa’s previously announced stock buyback program or its dividend policy, it said. Shares of Visa were flat in the extended session after ending the regular trading day up 0.8%.
