The payments processor, which has seen shares fall 20 percent since its 2015 initial public offering, is making progress strengthening its balance sheet and rebuilding its business, Barron's said.

Under Chief Executive Officer Frank Bisignano, First Data has improved its technology, paid down debt and got creditors to postpone to 2021 $5 billion in debt payments that were to be payable in 2018. Improved technology and salesmanship should help First Data generate more revenue, Barron's said.

First Data is betting on a new platform called Clover which helps small businesses manage payments more easily. The product it intended to increase client stickiness.

First Data's shares, at around $11, trade at eight times estimated 2016 earnings which is less than half the level of some competitors, Barron's added.
