Dear Fellow Shareholders:

Over the past three years, IGT’s Board of Directors and management team have successfully charted a course for the Company that is both strategically and financially sound. As a result, IGT’s financial performance has improved, and significant capital has been returned directly to shareholders. Today, the Company is positioned for sustained growth through continued investment in its core electronic gaming business and disciplined investments in related business opportunities and new markets.

In connection with the upcoming Annual Meeting of Shareholders, you will face an

important decision about the future of your investment in the Company. Ader Investment Management LP, on behalf of former IGT Chairman and CEO Charles N. Mathewson and Richard H. Pickup, a longtime associate of Mr. Mathewson, has nominated three directors for election to the Company’s Board at the 2013 Annual Meeting. The Mathewson Group has indicated that it has beneficial ownership of approximately 3% of total IGT shares and intends to nominate Mr. Mathewson and two others.

Your Board comprises eight highly qualified and experienced directors–Paget L. Alves, Janice Chaffin, Greg Creed, Patti S. Hart, Robert J. Miller, David E. Roberson, Vincent L. Sadusky and Philip G. Satre. In the coming weeks, you will receive the Company’s proxy materials, including a WHITE proxy card. The IGT Board recommends that you vote FOR all of IGT’s directors on the WHITE proxy card in advance of the Company’s 2013 Annual Meeting.

The Board and management team remain confident that the continued execution of the IGT growth strategy will create significant shareholder value.

IGT’s Financial Performance is Strong and Continues to Improve
Under this management team, IGT is delivering the strong and improving financial results that the Board expects from the successful execution of its strategy.

IGT is an Innovative Industry Leader, Shaping the Future of Gaming Entertainment
IGT is building upon its thirty-year tradition of leading innovation and reimagining the gaming experience. From the casino floor to the internet to mobile devices, IGT is propelling the evolution of gaming.

IGT Takes a Balanced Approach to Investing in its Business and Returning Capital to Shareholders
Since 2009, the Company has prudently allocated capital to drive growth and return capital to shareholders.

IGT’s Board Is Acting in the Best Interests of All Shareholders
IGT’s highly experienced eight-member Board is committed to strong corporate governance and is open to communications with shareholders.

IGT Has a Strong Strategy to Take the Company Forward – Do Not Allow Mr. Mathewson to Take Us Backward
The Company believes that its strategy is the right one to propel IGT into the future and that the election of Mr. Mathewson and his associates would be a step in the wrong direction. Shareholders should consider the facts about Mr. Mathewson’s leadership.

The Remaining Two Mathewson Group Nominees Would Not Be Additive to the Board and Should Be Rejected
The Board believes that the other two candidates the Mathewson Group intends to nominate – Raymond J. Brooks and Daniel B. Silvers – would negatively impact the strength of IGT’s Board. IGT believes that the nominees do not offer diversity or experience, nor do they offer any unique or necessary skills that are not already present on the Board.

Mr. Ader’s Confusing Statements Demonstrate a Lack of Credibility
The IGT Board strongly believes that the Mathewson Group and Mr. Ader seek to advance an agenda that would not be in the best interests of all IGT shareholders. Furthermore, we find Mr. Ader’s recent actions questionable. As disclosed in Mr. Ader’s own filings, on December 20, 2012 IGT received his Notice of Intent to Nominate in which Mr. Ader stated that he would nominate himself and the other three nominees of the Mathewson Group. Two weeks later, Mr. Ader updated his Notice with additional information about himself. Then, on January 10, 2013, Mr. Ader further updated his Notice, withdrawing his name from his proposed slate of nominees. The following day, in a public statement Mr. Ader denied his withdrawal, but then confirmed his withdrawal in his preliminary proxy filing with the SEC. We believe these actions demonstrate that Mr. Ader and the Mathewson Group lack credibility and are not suitable to represent shareholders.

The Board Believes Its Directors are Best Equipped to Protect and Grow Your Investment in IGT
The IGT Board is focused on the future. The Company is executing its strategy, meeting its financial objectives and positioning itself for long-term industry leadership and profitability. IGT’s highly experienced, engaged and independent Board is acting in the best interests of

all shareholders. In conclusion, the IGT Board recommends that you vote FOR all of IGT’s directors on the WHITE proxy card in advance of the Company’s 2013 Annual Meeting.

On behalf of the International Game Technology Board of Directors:

Adjusted earnings per share from continuing operations is a non-GAAP financial measure. We believe that certain non-GAAP measures, when presented in conjunction with comparable GAAP (Generally Accepted Accounting Principles) measures, are useful because that information is an appropriate measure for evaluating our operating performance. Non-GAAP information is used to evaluate business performance and management’s effectiveness. These measures should be considered in addition to, not as a substitute for, or superior to, measures of financial performance prepared in accordance with GAAP. Non-GAAP measures may not be calculated in the same manner by all companies and therefore may not be comparable.
