 Non-GAAP Financials  Included in this presentation are certain non-GAAP financial measures, including EBITDA, Adjusted EBITDA, Adjusted EBITDA Margin, Adjusted Operating Margin, and Organic Revenue, designed to supplement, and not substitute for, the financial information presented in accordance with generally accepted accounting principles in the United States of America because management believes such measures are useful to investors.The Companies have not reconciled the forward-looking Adjusted EBITDA guidance included in this presentation to the most directly comparable GAAP financial measure because this cannot be done without unreasonable effort due to the high variability, complexity and low visibility with respect to amounts for impairments, restructuring costs, acquisition related expenses, income taxes and other non-cash expenses and adjusting items which are excluded from the calculation of Adjusted EBITDA. For the same reasons, the Companies are unable to address the probable significance of the unavailable information, which could have a potentially unpredictable, and potentially significant, impact on its future GAAP financial results.Certain financial measures and other information have been adjusted for the proposed transaction between Gardner Denver and Ingersoll Rand and transactions related thereto and Ingersoll Rand’s pending acquisition of Precision Flow Systems. When presenting such information, the amounts are identified as “Pro forma.” The Pro forma financial measures are based on preliminary estimates, accounting judgments and currently available information and assumptions that management believes are reasonable. Accordingly, the Pro forma financial data is not necessarily indicative of IndustrialCo’s or ClimateCo’s financial position or results of operations had the transactions described above for which we are giving Pro forma effect actually occurred on the dates indicated.  3
