Appendix


Appendix Xylem Inc. Non-GAAP Measures Management reviews key performance indicators including revenue, gross margins, segment operating income and margins, orders growth, working capital and backlog, among others. In addition, we consider certain non-GAAP (or adjusted ) measures to be useful to management and investors evaluating our operating performance for the periods presented, and to provide a tool for evaluating our ongoing operations, liquidity and management of assets. This information can assist investors in assessing our financial performance and measures our ability to generate capital for deployment among competing strategic alternatives and initiatives, including but not limited to, dividends, acquisitions, share repurchases and debt repayment. These adjusted metrics are consistent with how management views our business and are used to make financial, operating and planning decisions. These metrics, however, are not measures of financial performance under GAAP and should not be considered a substitute for revenue, operating income, net income, earnings per share (basic and diluted) or net cash from operating activities as determined in accordance with GAAP. We consider the following items to represent the non-GAAP measures we consider to be key performance indicators, as well as the related reconciling items to the most directly comparable measure calculated and presented in accordance with GAAP. The non-GAAP measures may not be comparable to similarly titled measures reported by other companies. “EBITDA” defined as earnings before interest, taxes, depreciation and amortization expense. “Adjusted EBITDA” reflects the adjustments to EBITDA to exclude share-based compensation charges, restructuring and realignment costs, gain or loss from sale of businesses and special charges. Adjusted EBITDA Margin defined as adjusted EBITDA divided by total revenue. “Realignment costs” defined as costs not included in restructuring costs that are incurred as part of actions taken to reposition our business, including items such as professional fees, severance, relocation, travel, facility set-up and other costs. “Special charges defined as costs incurred by the Company, such as acquisition and integration related costs, non-cash impairment charges and both operating and non-operating adjustments for costs related to the UK pension plan buyout. 16

Appendix Evoqua Non-GAAP Measures The Company reports its financial results in accordance with U.S. generally accepted accounting principles (“GAAP”). However, management believes that certain non-GAAP financial measures provide users of the Company's financial information with additional useful information in evaluating operating performance. We use the non-GAAP financial measures listed below in this presentation to help readers in evaluating the strength and financial performance of our core business. The presentation of this additional information is not meant to be considered in isolation or as a substitute for GAAP measures. “EBITDA” defined as earnings before interest, taxes, depreciation and amortization expense. “Adjusted EBITDA” reflects the adjustment to EBITDA to exclude certain other items, including restructuring and related business transformation costs, purchase accounting adjustment costs, share-based compensation, sponsor fees, transaction costs and other gains, losses and expenses. Adjusted EBITDA margin defined as adjusted EBITDA as a percentage of revenue 18
