Global Payments Inc. GPN

I am trying to understand why this stock seems to be undervalued with a Forward P/E under 6, PEG ratio around 0.5 and price to book at 0.9. It's a profitable company that has year over year growth. over the past year, the stock price is down considerably. Is it the change in business strategy over the past year with the merger of Worldpay that has people selling it? Seems like there is value here.
