National Information Services, Inc.

Ladies and Gentlemen:

We have acted as Georgia counsel for Fidelity National Information Services, Inc., a Georgia corporation (“FIS”), in connection with the registration statement on Form S-4 (File No. 333-230858) (as amended, the “Registration Statement”) filed by FIS with the Securities and Exchange Commission under the Securities Act of 1933, as amended (the “Securities Act”), relating to the registration of the issuance of up to 297,279,730 shares (the “Shares”) of FIS’s common stock, par value $0.01 per share, to be issued in connection with the Agreement and Plan of Merger (the “Merger Agreement”), dated as of March 17, 2019, by and among Worldpay, Inc., a Delaware corporation (“Worldpay”), FIS and Wrangler Merger Sub, Inc., a Delaware corporation.

As such counsel, and as a basis for the opinion hereinafter set forth, we have examined and are familiar with (a) the Merger Agreement; (b) FIS’ amended and restated articles of incorporation, as amended, including by the articles of amendment (the “Articles of Amendment”) effective July 31, 2019; (c) FIS’ amended and restated bylaws, as amended to date; (d) the Registration Statement; and (e) relevant resolutions of the directors of FIS approving the Merger Agreement (and the transactions contemplated thereby), the Articles of Amendment and the registration of the Shares. In addition, we have made such investigations of law and have examined such certificates of public officials and officers of FIS and such other documents and records as we have deemed necessary for purposes of this opinion letter.

We have relied on statements and representations of officers of FIS and other representatives of FIS and its agents. Other than as stated in this opinion letter, we have not independently established or verified any facts relevant to the opinion expressed herein. In our examination, we have assumed the completeness and authenticity of any document submitted to us as an original, the completeness and conformity to the originals of any document submitted to us as a copy, the authenticity of the originals of such copies, the genuineness of all signatures and the legal capacity and mental competence of natural persons.

This opinion letter is given, and all statements herein are made, in the context of the foregoing.

This opinion letter is based, as to matters of law, solely on the Georgia Business Corporation Code and judicial interpretations of such law.
