Dear Fellow Shareholder:

MRC is an activist hedge fund that is waging a proxy fight with an agenda that puts your investment and the existence of E & E as a public shareholder company at risk.

YOUR VOTE IS VERY IMPORTANT TO PROTECT YOUR INVESTMENT IN E & E.

Ecology and Environment, Inc. (the “Company” or “E & E”) believes Mill Road Capital II L.P. and its affiliates (collectively “MRC”) launched this costly and distracting proxy contest, with very self-serving goals, to install handpicked directors to pave the way for MRC to sell your Company to itself. This going private agenda has been formally rejected by the

Company and the Company further found the MRC nominees to be lesser qualified than the Company’s slate of director candidates. Obviously, MRC recognizes the substantial future opportunity at E & E; but MRC’s agenda would put all of that upside in the hands of one shareholder: MRC.

MRC has publicly stated that it will solicit proxies in opposition to the nomination of the

Company’s two highly qualified Class A director candidates to serve on the E & E Board of Directors (the “Board”). We expect that MRC’s nominees would push a distracting agenda intended to seduce the Class B shareholders to pursue a sale that would result in a substantial loss of an investment opportunity and future profits, especially for Class A shareholders. MRC’s ongoing efforts to advance its own self-serving agenda will be disruptive to E & E’s ongoing growth strategy initiatives.

Do not help MRC pursue its stated agenda to eliminate the publicly held shares through a going-private transaction. That agenda will lead to the end of E & E as a publicly traded, world class, independent, environmental consulting company that is capable of and committed to solving the complex environmental issues of our time.

VOTE “FOR” THE E & E BOARD NOMINEES ON THE WHITE PROXY CARD TODAY

The 2017 Annual Meeting of Shareholders of Ecology and Environment, Inc. (the “Annual

Meeting”) will be held on Thursday, April 20, 2017. You face an important choice regarding the composition of the Board and the future growth and profitability of E & E. Your vote is important, no matter how many shares you own.

Kindly sign and date the enclosed WHITE proxy card and return it in the postage-paid envelope provided or by voting over the Internet or telephone today. But please DO NOT return or otherwise vote any green proxy card sent to you by MRC.

The E & E Board and management team continue to take disciplined and decisive action to maintain shareholder returns and prepare for a future of growth.

Total net income attributable to E & E improved $2.3 million from a loss of $1.4 million in 2014 to income of $3.4 million in 2015, and income of $0.9 million in 20161, despite reductions in net revenues from U.S. and South American operations. This turnaround is attributable to aggressive implementation of strategic initiatives by the Board and management team, despite the recession in the U.S. and foreign economies and the collapses in the mining sector and oil prices.

Further, from 2012 to 2016, E & E’s net cash position (defined as total cash minus total debt) improved from $1 million of net debt in 2012 to almost $11 million of net cash in 2016.

During this five year period, E & E dividends to shareholders were between 4% and 5% of share price, amounting to more than $10 million, and E & E reduced more than $12 million of debt with no significant change in operating cash balances.

Note: All amounts in the chart above are directly obtained from, or are calculated from amounts derived from, the audited financial statements included in our SEC Form 10-K filings for the fiscal years ended July 31, 2014, 2015 and 2016.

Many of E & E’s shareholders own the Company for its core environmental ethics and values and its reliable dividend, which we have paid consecutively for 30 years. Now is not the time to turn away from a strategy that has been successfully implemented over the past four years and has positioned E & E to achieve substantial future growth.

All E & E shareholders deserve the opportunity to realize the benefits of E & E’s growth initiatives.

The E & E Director Nominees are more qualified and better suited than those offered by MRC.

After carefully considering 12 potential candidates, including those nominated by MRC, the Board has nominated Michael S. Betrus for reelection as a Class A director, Robert J. Untracht for election as a new Class A director, and Marshall A. Heinberg for election as a new Class B director, in addition to four incumbent Class B directors.

Michael S. Betrus, age 64, has more than 40 years of accounting, financial management, contractual oversight and forecasting experience. His familiarity with the Company, his CPA and accounting experience, his experience in integration of acquired entities, and his steadfast commitment to a long-term growth strategy aligns well with the Company’s goals. He previously served as Senior Vice President and Chief Financial Officer of Power Drives, Inc., a manufacturing and industrial distribution company in Buffalo, New York. Prior to that, he served as the Accounting and Contracts Manager for Ecology and Environment, Inc. and he previously was Chief Financial Officer and Controller for the ARO Corporation in its Life Supports Products Division.

As Chairman of the Audit Committee, Mr. Betrus’ accounting skills and experience with financial management have proven particularly valuable to the Board, especially in addressing our challenges in South America. He has extensive experience with our industry and with our Company specifically, having joined E & E’s Board in 2014.

Robert J. Untracht, age 67, has extensive public and private company board experience. He currently serves as a member of the Board of Directors and the Chairman of the Audit Committee of Siteworx, LLC and Hexanika, Inc., two private consulting services companies. He previously served as a Member of the Board of Directors and Chairman of the Audit Committee at DoubleLine Funds from 2010 to 2012 and Discus Dental, LLC from 2008 to 2010 and as a Member of the Board of American Mobile Power Systems, Inc., a private company, and SM&A, Inc., a public consulting services company, for a period of six years.

Mr. Untracht’s experience in consulting and financial services will offer E & E a fresh and independent perspective to support the Company’s growth strategy. He previously served as a financial reporting consultant to ILFC (a separate public company for the debt reporting purposes of AIG, its parent company). Prior to that, Mr. Untracht served as an Instructor of Accounting at the Anderson Graduate School of Management at UCLA and as an Associate Professor of Accounting at the New York Institute of Technology. Prior to this, he served in various audit positions, including Partner, at Ernst & Young, LLP.

Marshall A. Heinberg, age 59, has had a long and distinguished investment banking career with Oppenheimer and in his consulting practice, which is directly additive to the

Company’s focus on acquisitions. He has been directly involved in more than a dozen capital markets and/or merger and acquisition transactions for many of the leading environmental engineering and consulting and waste management firms.

The E & E Board slate is composed of four independent candidates who are qualified to support a strategy of growth, and are committed to acting in the best interests of all E & E shareholders. By contrast, we believe that if MRC nominees Mr. Jacobs and Mr. El-Hillow were to be elected, there would only be two independent directors on the Board because Mr. Jacobs and Mr. El-Hillow are not independent, but rather agents of MRC and its agenda. The Board’s two Class A nominees offer superior skillsets that complement those of the other director nominees to comprise a carefully cultivated set of expertise.

In contrast to the E & E nominees, the Board believes those offered by MRC are less qualified. The Board has thoroughly reviewed MRC’s nominees and unanimously concluded that replacing either of the Board’s Class A candidates for election with either of MRC’s nominees would reduce the capability of the Board.

In fact, the MRC nominees have little or no experience advising or operating an environmental consulting services company, or advising a management team like E & E’s.

In comparison, the current Board and its nominees have extensive knowledge and familiarity with our industry, which is critical as the Company continues to successfully execute its strategic plan. MRC, a tiny investment company, has little experience in operating companies, especially one like E & E that operates in multiple languages in more than 25 offices and five countries. MRC has few employees and, to our knowledge, no technical expertise to contribute to E & E’s operations.

Simply put: It is the Board’s informed opinion that E & E’s slate of candidates are far better qualified to direct the Company’s growth strategy than those proposed by MRC.

The future success of the Company will be determined by its operating management and staff, which will operate more effectively if directed by a cohesive Board rather than a fractious one.

Alternatively, if you are a record holder you can vote your shares in person by attending the Annual Meeting. You will be given a ballot at the Annual Meeting. However, if your shares are held in the name of a broker, bank or other nominee, and you plan on voting by attending the Annual Meeting in person, you must bring a statement from your brokerage account or a letter from the person or entity in whose name the shares are registered indicating that you are the beneficial owner of those shares as of the Annual

Meeting’s record date—you will not be able to vote by attending the Annual Meeting without a legal proxy from the record holder of your shares.

On behalf of your Board of Directors and management team, we thank you for your continued support.

Sincerely,
