Forward-looking statements Safe Harbor Statement This presentation contains forward-looking statements, which may concern our plans, objectives, outlook, goals, strategies, future events, future net sales or performance, capital expenditures, financing needs, future restructuring, plans or intentions relating to expansions, business trends and other information that is not historical information. All forward-looking statements are based upon information available to us on the date of this release and are subject to risks, uncertainties and other factors, many of which are outside of our control, which could cause actual results to differ materially from the results discussed in the forward-looking statements. Risks that could cause such results to differ include: failure to capitalize on, and volatility within, the Company's growth drivers, including internet connectivity, clean energy, and safety and protection, as well as specific market and industry trends within these growth drivers; business, economic and political conditions in the United States and abroad, particularly in China, South Korea, Germany, Hungary and Belgium, where we maintain significant manufacturing, sales or administrative operations; fluctuations in foreign currency exchange rates; research and development efforts; competitive developments; business development transactions and related integration considerations; the outcome of ongoing and future litigation, including our asbestos-related product liability litigation; and changes in laws and regulations applicable to our business. For additional information about the risks, uncertainties and other factors that may affect our business, please see our most recent annual report on Form 10-K and any subsequent quarterly reports on Forms 10-Q filed with the Securities and Exchange Commission. Rogers Corporation assumes no responsibility to update any forward-looking statements contained herein except as required by law. Non-GAAP Information This presentation includes the following financial measures that are not presented in accordance with generally accepted accounting principles in the United States of America ( GAAP ): (1) Adjusted earnings per diluted share, which the Company defines as earnings per diluted share excluding acquisition-related amortization of intangible assets and discrete items, such as restructuring expenses, certain impairments, environmental accrual adjustments, acquisition and related integration costs, non-recurring tax changes, asbestos-related charges, and gains or losses on asset or business dispositions (collectively, Discrete Items ) (2) Adjusted operating income, which the Company defines as operating income excluding acquisition-related amortization of intangible assets and Discrete Items; (3) Adjusted operating margin, which the Company defines as operating margin excluding acquisition-related amortization of intangible assets and Discrete Items; (4) Adjusted EBITDA, which the company defines as net income excluding interest expense, income tax expense, depreciation and amortization, and Discrete Items; and (5) Adjusted EBITDA margin, which the Company defines as net income margin excluding interest expense, income tax expense, depreciation and amortization, and Discrete Items. Management believes each of these measures is useful to investors because they allow for comparison to the Company s performance in prior periods without the effect of items that, by their nature, tend to obscure the Company s core operating results due to the potential variability across periods based on the timing, frequency and magnitude. As a result, management believes that adjusted earnings per diluted share, adjusted EBITDA, adjusted operating income, adjusted operating margin and adjusted EBITDA margin enhance the ability of investors to analyze trends in the Company s business and evaluate the Company s performance relative to peer companies. However, non-gaap financial measures have limitations as analytical tools and should not be considered in isolation from, or solely as alternatives to, financial measures prepared in accordance with GAAP. In addition, these non-gaap financial measures may differ from similarly named measures used by other companies. Reconciliations of the differences between these non-gaap financial measures and their most directly comparable financial measures calculated in accordance with GAAP are set forth at the end of this document. Management also believes that providing net sales information on a constant currency or FX adjusted basis is useful to investors as it allows for the comparison of net sales for the current period to past periods without the impact of changes in exchange rates (from various local currencies into US dollars) which occurred during the intervening time. To calculate constant currency or FX adjusted revenues, we converted current period local currency revenues to US dollars at prior period rates, and used the resulting US dollar revenues to calculate growth vs. the prior period reported revenues. 2
