Fifth Third Bancorp Announces Expected Impact of Vantiv Share Sale

CINCINNATI—(BUSINESS WIRE)— Vantiv, Inc. (NYSE: VNTV) recently priced a secondary offering of 38.6 million shares of Class A Common Stock being sold on behalf of selling shareholders, including 15.6 million shares being sold by Fifth Third (Nasdaq: FITB). Additionally, Vantiv announced that it has entered into an agreement to repurchase 17.5 million shares of the shares being sold by the selling shareholders in the offering. The combination of the sale and Vantiv’s repurchase of shares would result in an approximate 15 percent reduction in our ownership position in Vantiv (excluding the warrant noted below). As previously communicated, our purpose in the sale is to continue the process of monetizing the remaining portion of our stake in Vantiv in a considered, orderly fashion over time.

Upon the settlement of this transaction, we would expect to recognize a pre-tax gain of approximately $225 million (approximately $145 million after-tax) during the second quarter of 2013. Following the settlement, Fifth Third would continue to hold approximately 54.6 million Class B units of Vantiv Holding, LLC, which may be exchanged for Class A common stock of Vantiv, Inc. on a one-for-one basis, as well as a warrant that is exercisable and exchangeable into Vantiv Inc. Class A Common Stock. These securities are subject to certain terms and restrictions. Fifth Third would have a remaining economic interest of approximately 28 percent of Vantiv’s future earnings (before consideration of the potential impact of an exercise of the underwriters’ overallotment option, as discussed below). Our interest is accounted for under the equity method, and these earnings would be reduced reflecting the reduction in our ownership position as a result of the sale and Vantiv’s repurchase transaction.

The underwriters of the offering have been granted an option, solely to cover over-allotments and exercisable for 30 days from the date of pricing, to purchase up to an additional 2.1 million shares (0.8 million shares from Fifth Third) of Class A Common Stock of Vantiv, Inc. at the share price of the secondary offering. If exercised, we would expect any such action to change the impacts to Fifth Third caused by the initial sale, with any such changes limited to no more than 5 percent of the initial impact described herein.

As previously announced on March 14, 2013, our ability to repurchase shares of Fifth Third common stock in an amount up to any after-tax gains realized by Fifth Third from the sale of Vantiv shares was not objected to by the Federal Reserve in its Comprehensive Capital Analysis and Review process.
