Report of Independent Registered Public Accounting Firm

The Plan Administrator

Total System Services, Inc.

2012 Employee Stock Purchase Plan:

We
have audited the accompanying statements of financial condition of the Total System Services, Inc. 2012 Employee Stock Purchase Plan (the Plan) as of December 31, 2016 and 2015, and the related statements of operations and changes in plan
equity for each of the years in the three-year period ended December 31, 2016. These financial statements are the responsibility of the Plans management. Our responsibility is to express an opinion on these financial statements based on
our audits.

We conducted our audits in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards
require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement. An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the
financial statements. An audit also includes assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement presentation. We believe that our audits provide a reasonable
basis for our opinion.

In our opinion, the financial statements referred to above present fairly, in all material respects, the financial condition of
the Plan as of December 31, 2016 and 2015, and the results of its operations and changes in its plan equity for each of the years in the three-year period ended December 31, 2016, in conformity with U.S. generally accepted accounting
principles.

TOTAL SYSTEM SERVICES, INC.

2012 EMPLOYEE STOCK PURCHASE PLAN

Notes to Financial Statements

December 31, 2016, 2015 and 2014



|(1) | Description of the Plan
|--- | -----------------------

On January 31, 2012, the board of directors of Total
System Services, Inc. (TSYS) adopted the Total System Services, Inc. 2012 Employee Stock Purchase Plan (the Plan). The Plan was approved by the TSYS shareholders on May 1, 2012, and became effective as of July 1, 2012. On July 1,
2012, the plan assets of the predecessor plan, the Total System Services, Inc. Employee Stock Purchase Plan, were rolled over into the Plan. The Plan is designed to enable participating Total System Services, Inc. (TSYS) and participating
subsidiaries employees to purchase shares of common stock of TSYS at prevailing market prices from contributions made by them and by TSYS and its subsidiaries (the Participating Employers).

TSYS serves as the Plan Administrator. As of September 1, 2015, the Plan agent is Fidelity Stock Plan Services, LLC, hereafter referred
to as Agent. Prior to September 1, 2015, the Plan agent was ComputerShare Shareowner Services, LLC.

All employees based
in the United States who work 20 hours per week or more are eligible to participate in the Plan on the first payroll date after completing three months of continuous employment. Employees of TSYS or TSYS affiliates who are employed in
a country other than the United States are not eligible to participate in the Plan unless the Plan is registered or qualified in the employees country of residence.

Participants contribute to the Plan through payroll deductions as a percentage of compensation. The maximum allowable contribution ranges from
3% to 7% of compensation based on years of service. The maximum amount of compensation that may be taken into account under the Plan on an annual basis is $250,000. The minimum allowable contribution is 1% of compensation. Matching contributions to
the Plan are to be made by the Participating Employers in an amount equal to 0-50% of each participants contribution, with the percentage of the matching contribution to be set by the TSYS Board of Directors. As of December 31, 2016 and
2015, the Participating Employers match was 15%. Participants are immediately vested in their contributions and Participating Employers matching contributions.

The Plan provides, among other things, that all expenses of the Plan and its administration shall be paid by TSYS with the exception of
brokers fees, commissions, and transaction costs, which are included in the cost of each participants investment in common stock of TSYS.

The Plan Agent purchases TSYS common stock on behalf of each participant with the participant contributions and company contributions. From
Plan inception through August 31, 2015, TSYS common stock purchased through the Plan was held in the Plan for each participant. Effective September 1, 2015, concurrent with the change in Agent, shares of TSYS common stock purchased on
behalf of Plan participants, or amounts less than the full price of a share, are immediately distributed to each participants personal brokerage account. Dividends are no longer paid to participants through the Plan but are paid within their
brokerage account. Participants may choose dividends paid, or reinvested to purchase additional shares. Accordingly, subsequent to September 1, 2015, there is a zero balance for Plan equity.

Within their personal brokerage account, the Plan provides that all shares must be held for a minimum period of six months, during which the
shares cannot be sold, transferred, assigned, pledged, or otherwise disposed of. Subsequent to the six months holding period, the Plan provides that each participant may withdraw at any time all or some of his or her account balance. The participant
may elect to receive the proceeds in the form of shares of common stock of TSYS or in lump-sum cash distributions.

The Plan provides that
upon termination of participation in the Plan, each former participant will receive, at his or her discretion, (i) the full number of shares of TSYS common stock held on his or her behalf by the Agent, together with a check for any fractional
share interest, or (ii) a lump-sum cash distribution for the proceeds of the sale of all shares held on his or her behalf by the Agent.

2012 EMPLOYEE STOCK PURCHASE PLAN

Notes to Financial Statements

December 31, 2016, 2015 and 2014

Participation in the Plan shall automatically terminate upon termination of a participants employment whether by death, retirement, or
otherwise.

TSYS expects to maintain the Plan indefinitely, but reserves the right to terminate or amend the Plan at any time, provided,
however, that no termination or amendment shall affect or diminish any participants right to the benefit of contributions made by him or her, or his or her Participating Employer prior to the date of such amendment or termination.

TSYS reserves the right to suspend Participating Employer contributions to the Plan if its board of directors feels that TSYS financial
condition warrants such action.



|(2) | Summary of Significant Accounting Policies
|--- | ------------------------------------------

The preparation of financial statements in
conformity with U.S. generally accepted accounting principles requires management to make estimates and assumptions that affect the reported amounts of assets, liabilities, and changes therein, and disclosure of contingent assets and
liabilities. Actual results could differ from those estimates.

From Plan inception through August 31, 2015, TSYS common stock
purchased through the Plan was held in the Plan for each participant. The Plans investment in common stock of TSYS was stated at fair value, which was based on the closing price at year-end obtained by
using market quotations on the principal public exchange market for which such securities were traded.

The Plans investment in the
common stock of TSYS was exposed to market and credit risks. Due to the level of risk associated with investment securities, it was at least reasonably possible that changes in the values of investment securities could have occurred in the near term
and that such changes could have materially affect the amounts reported in the Plans financial statements.

The realized gain or
loss on distributions to participants was determined by computing the difference between the average cost per share and the fair value per share at the date of the distribution to the participants, less transaction costs.

With the conversion to Fidelity as the Plan Agent, the plan no longer holds assets. Prior to the conversion contributions to the Plan by TSYS
and participating employees were accounted for on the accrual basis. Withdrawals were accounted for upon distribution.

Purchases and
sales of TSYS common stock were reflected on a trade-date basis. Dividend income was accrued on the record date.



|(3) | Tax Status of the Plan
|--- | ----------------------

The Plan is not qualified under Sections 401(a) or 501(a)
of the Internal Revenue Code of 1986, as amended. The Plan does not provide for income taxes because any income is taxable to the participants. Participants in the Plan must treat as compensation income their pro rata share of contributions made to
the Plan by their Participating Employer. Cash dividends paid on common stock of TSYS purchased under the Plan will be taxable to the participants on a pro rata basis for Federal and state income tax purposes during the year any such dividend is
received by the participant or the Plan. Upon disposition of the common stock of TSYS purchased under the Plan, participants must treat any gain or loss as long-term or
short-term capital gain or loss depending upon when such disposition occurs.
