Exhibit 99.1

Diebold’s Takeover Offer to Wincor Nixdorf Shareholders

Creating the premier self-service company for financial and retail markets

February 2016

Use of non-GAAP financial information

Diebold has included non-GAAP financial measures in this presentation to supplement Diebold’s condensed consolidated financial statements presented on a GAAP basis. Definitions of these non-GAAP financial measures and reconciliations of these non-GAAP financial measures to the most directly comparable GAAP financial measures are included elsewhere in this presentation.

Diebold’s management uses constant currency, non-GAAP product, service and total gross margins, non-GAAP operating expense, non-GAAP operating profit, non-GAAP tax rate, non-GAAP net earnings, and non-GAAP diluted earnings per share, and excludes gains, losses or other charges that are considered by Diebold’s management to be outside of Diebold’s core business segment operating results. Net debt and free cash flow are liquidity measures that provide useful information to management about the amount of cash available for investment in Diebold’s businesses, funding strategic acquisitions, repurchasing stock and other purposes. The company calculates constant currency by translating the prior year results at the current year exchange rate.

These non-GAAP financial measures may have limitations as analytical tools, and these measures should not be considered in isolation or as a substitute for analysis of Diebold’s results as reported under GAAP. Items such as impairment of goodwill and intangible assets, though not directly affecting Diebold’s cash position, represent the loss in value of goodwill and intangible assets over time. The impairment expense associated with this loss in value is not included in non-GAAP operating profit, non-GAAP net earnings, non-GAAP diluted earnings per share and therefore does not reflect the full economic effect of the loss in value of those goodwill and intangible assets. In addition, items such as restructuring charges and non-routine expenses that are excluded from non-GAAP gross profit, non-GAAP operating expense, non-GAAP operating profit, non-GAAP net earnings, and non-GAAP diluted earnings per share can have a material impact on cash flows and earnings per share. In addition, free cash flow does not represent the total increase or decrease in the cash balance for the period. The non-GAAP financial information that we provide also may differ from the non-GAAP information provided by other companies.

We compensate for the limitations on our use of these non-GAAP financial measures by relying primarily on our GAAP financial statements and using non-GAAP financial measures only supplementally. We also provide robust and detailed reconciliations of each non-GAAP financial measure to the most directly comparable GAAP measure, and we encourage investors to review carefully those reconciliations.

We believe that providing these non-GAAP financial measures in addition to the related GAAP measures provides investors with greater transparency to the information used by Diebold’s management in its financial and operational decision-making and allows investors to see Diebold’s results “through the eyes” of management. We further believe that providing this information better enables investors to understand Diebold’s operating performance and to evaluate the efficacy of the methodology and information used by management to evaluate and measure such performance.

Forward-looking statements

In this presentation, statements that are not reported financial results or other historical information are “forward-looking statements”. Forward-looking statements give current expectations or forecasts of future events and are not guarantees of future performance. These forward-looking statements relate to, among other things, the company’s future operating performance, the company’s share of new and existing markets, the company’s short- and long-term revenue and earnings growth rates, and the company’s implementation of cost-reduction initiatives and measures to improve pricing, including the optimization of the company’s manufacturing capacity.

The use of the words “will,” “believes,” “anticipates,” “expects,” “intends” and similar expressions is intended to identify forward-looking statements that have been made and may in the future be made by or on behalf of the company. Although the company believes that these forward-looking statements are based upon reasonable assumptions regarding, among other things, the economy, its knowledge of its business, and on key performance indicators that impact the company, these forward-looking statements involve risks, uncertainties and other factors that may cause actual results to differ materially from those expressed in or implied by the forward-looking statements. The company is not obligated to update forward-looking statements, whether as a result of new information, future events or otherwise.

Readers are cautioned not to place undue reliance on these forward-looking statements, which speak only as of the date hereof. Some of the risks, uncertainties & other factors that could cause actual results to differ materially from those expressed in or implied by the forward-looking statements include, but are not limited to

the Company’s ability to successfully consummate the purchase of Wincor Nixdorf, including obtaining the necessary financing and satisfying closing conditions;

the Company’s ability to realize benefits from the strategic business alliance with Securitas AB;

competitive pressures, including pricing pressures and technological developments;

changes in the company’s relationships with customers, suppliers, distributors and/or partners in its business ventures;

changes in political, economic or other factors such as currency exchange rates, inflation rates, recessionary or expansive trends, taxes and regulations and laws affecting the worldwide business in

each of the company’s operations;

global economic conditions, including any additional deterioration and disruption in the financial markets, including the bankruptcies, restructurings or consolidations of financial institutions, which

could reduce our customer base and/or adversely affect our customers’ ability to make capital expenditures, as well as adversely impact the availability and cost of credit;

acceptance of the company’s product and technology introductions in the marketplace;

the finalization of the company’s financial statements for the periods discussed in this presentation;

the company’s ability to maintain effective internal controls;

changes in the company’s intention to further repatriate cash and cash equivalents and short-term investments residing in international tax jurisdictions, which could negatively impact foreign and

domestic taxes;

unanticipated litigation, claims or assessments, as well as the outcome/impact of any current/pending litigation, claims or assessments, including but not limited to the company’s Brazil tax dispute;

variations in consumer demand for financial self-service technologies, products and services;

potential security violations to the company’s information technology systems;

the investment performance of our pension plan assets, which could require us to increase our pension contributions, and significant changes in healthcare costs, including those that may result from

government action;

the amount and timing of repurchases of the company’s common shares, if any; and

the company’s ability to achieve benefits from its cost-reduction initiatives and other strategic changes, including its multi-year realignment plan and other restructuring actions, as well as its business

process outsourcing initiative.

This document is based upon domestic German tax laws in effect as of the date hereof.

By their nature, forward-looking statements involve risks and uncertainties because they relate to events and depend on circumstances that may or may not occur in the future.
