After Vantiv (VNTV) agreed to buy Worldpay, RBC Capital analyst Daniel Perlin says that the deal is "defensive today" because of "weakness in big-box mall retail," deflationary grocery pricing, after the Whole Foods (WFM) deal, and "the looming threat of JPMorgan's (JPM) closed-loop network potentially driving down acquiring fees." But the analyst thinks that the deal will certainly create value over the long-term, due to Worldpay's global platform and the fact that its aggregate revenue yields are about 47% higher than those of Vantiv. The analyst keeps a $73 price target and an Outperform rating on Vantiv.
