ACI Worldwide (Nasdaq: ACIW) has acquired Online Resources (Nasdaq: ORCC), a provider of e-payment services, for $263 million.

The price tag works out to $3.85 per share in cash. Boards of directors from both companies have approved the transaction.

ACI plans to integrate Online into its business to make online and mobile banking, bill payment and other services available to financial institutions. The deal will broaden ACI’s customer base.

Naples, Fla.-based ACI Provides electronic-payment services for financial institutions, retailers and other processors.

Online, headquartered in Chantilly, Va., processes more than 245 billion payment transactions per year, for both financial institutions and other billers.

Jim Bronner of Wells Fargo Securities served as ACI’s financial adviser, while partners Robert Profusek, Thomas Bark and Fionna Schaeffer of Jones Day served as legal counsel. Jim Bunn of Raymond James & Associates Inc. was Online Resources financial adviser. SunTrust Robinson Humphrey Inc. provided financial advice to a special committee of Online’s board of directors, and Morris Manning & Martin LLP served as the counsel’s legal adviser.

The transaction was announced on the heels of Fidelity National Information Services' (NYSE: FIS) agreeing to buy the remaining 78 percent interest in mFoundry, a provider of mobile banking and payments technology, for $120 million. FIS already held a 22 percent interest in mFoundry. The company expects the purchase to close by the end of the first quarter.
