2 Cautionary Note Regarding Forward-Looking Statements Cautionary Statement Under the Private Securities Litigation Reform Act; Non-GAAP Measures This press release contains “forward-looking” statements within the meaning of the Private Securities Litigation Reform Act of 1995, as amended. Such forward-looking statements include statements regarding the expected benefits of the acquisition of Mott, the expected impact of the acquisition on IDEX’s product offerings or proposed product offerings, IDEX’s combined existing and new customers and access to high-value end markets, the enhancement of IDEX’s business strategy, integration plans, the expected growth opportunities, profitability and synergies resulting from the acquisition, including the timing of such expected synergies, the present value of expected tax benefits, the anticipated long-term value to IDEX’s shareholders, the projected revenue, EBITDA and EBITDA margin of Mott and the related impact and timing for such impact on IDEX’s earnings, return on invested capital, and the expected timing for the closing of the transaction. These statements are subject to inherent uncertainties and risks that could cause actual results to differ materially from those anticipated at the date of this press release. The risks and uncertainties include, but are not limited to, the following: levels of industrial activity and economic conditions in the U.S. and other countries around the world, including uncertainties in the financial markets; pricing pressures, including inflation and rising interest rates and other competitive factors and levels of capital spending in certain industries; the impact of catastrophic weather events, natural disasters and public health threats; economic and political consequences resulting from terrorist attacks and wars; risks relating to the satisfaction of the closing conditions set forth in the definitive agreement; IDEX’s ability to integrate Mott and to acquire, integrate and operate other acquired businesses on a profitable basis; cybersecurity incidents; the relationship of the U.S. dollar to other currencies and its impact on pricing and cost competitiveness; political and economic conditions in foreign countries in which IDEX operates; developments with respect to trade policy and tariffs; interest rates; capacity utilization and the effect this has on costs; labor markets; supply chain conditions; market conditions and material costs; risks related to environmental, social and corporate governance issues, including those related to climate change and sustainability; and developments with respect to contingencies, such as litigation and environmental matters. Additional factors that could cause actual results to differ materially from those reflected in the forward-looking statements include, but are not limited to, the risks discussed in the “Risk Factors” section included in IDEX’s most recent annual report on Form 10-K and IDEX’s subsequent quarterly reports filed with the Securities and Exchange Commission (“SEC”) and the other risks discussed in IDEX’s filings with the SEC. The forward-looking statements included here are only made as of the date of this press release and management undertakes no obligation to publicly update them to reflect subsequent events or circumstances, except as may be required by law. Investors are cautioned not to rely unduly on forward-looking statements when evaluating the information presented here. Non-GAAP Measures. During this presentation we will discuss certain forward-looking non-GAAP financial measures, including EBITDA, EBITDA margin, adjusted earnings per share (EPS) and return on invested capital. We do not provide a reconciliation of forward-looking non-GAAP financial measures to the most directly comparable GAAP financial measures on a forward-looking basis because we are unable to predict certain items contained in the GAAP measures without unreasonable efforts. In addition, IDEX believes such reconciliation would imply a degree of precision that would be confusing or misleading to investors.
