Table of Contents REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM To the Board of Directors and Shareholders of Ecology and Environment, Inc. We have audited the accompanying consolidated statements of operations, comprehensive income, changes in shareholders’ equity, and cash flows for the year ended July 31, 2015 of Ecology and Environment, Inc. and its subsidiaries (collectively, the Company). The 2015 financial statements are the responsibility of the Company’s management. Our responsibility is to express an opinion on these financial statements based on our audit. We conducted our audit 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 consolidated financial statements are free of material misstatement. The Company is not required to have, nor were we engaged to perform, an audit of its internal control over financial reporting. Our audit included consideration of internal control over financial reporting as a basis for designing audit procedures that are appropriate in the circumstances, but not for purpose of expressing an opinion on the effectiveness of the Company’s internal control over financial reporting. Accordingly, we express no such opinion. An audit also includes examining, on a test basis, evidence supporting the amounts and disclosures in the consolidated financial statements, assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement presentation. We believe that our audit provides a reasonable basis for our opinion. In our opinion, the 2015 consolidated statements of operations, changes in shareholders’ equity and cash flows, present fairly, in all material respects, the results of its operations and its cash flows for the year ended July 31, 2015 in conformity with accounting principles generally accepted in the United States of America. /s/ Schneider Downs & Co., Inc.
