Safe Harbor and Disclaimers The following constitutes a “Safe Harbor” statement under the Private Securities Litigation Reform Act of 1995: Our presentation today and these slides contain forward-looking statements that involve a number of risks and uncertainties, including forward-looking statements about our expected future financial and operating performance, our market opportunities and demand for our products, our views of the trends in the industries we serve, and our capabilities and technological position in the market. Important factors that could cause actual results to differ materially from those indicated by such statements are set forth under the heading “Risk Factors” in Kadant’s quarterly report on Form 10-Q for the period ended March 29, 2014. These include risks and uncertainties relating to our dependence on process industries; significance of sales and operation of manufacturing facilities in China; oriented strand board market and levels of residential construction activity; commodity and component price increases or shortages; dependence on certain suppliers; international sales and operations; our acquisition strategy; our internal growth strategy; fluctuations in currency exchange rates; competition; soundness of suppliers and customers; our effective tax rate; future restructurings; soundness of financial institutions; our debt obligations; restrictions in our credit agreement; reliance on third-party research; protection of patents and proprietary rights; failure of our information systems or breaches of data security; fluctuations in our share price; and anti-takeover provisions. We undertake no obligation to publicly update any forward-looking statement, whether as a result of new information, future events, or otherwise.The following slides and related commentary address certain current goals and targets for Kadant. There can be no assurance that these goals and targets will be achieved and, in addition to the general risks and uncertainties of our business, they are based on a number of assumptions that may or may not prove accurate or achievable. These assumptions include our ability to identify and complete acquisitions that have the acquisition characteristics we desire and achieve the intended financial metrics, our ability and willingness to continue to pay dividends consistent with our recent practice, our ability to effect open market stock repurchases and our ability to implement our internal growth initiatives successfully and achieve the goals of such initiatives. Additionally, these goals and targets may change at any time and we undertake no obligations to update them. *© 2014 Kadant Inc. All rights reserved.

Use of Non-GAAP Financial Measures *© 2014 Kadant Inc. All rights reserved. Adjusted net income, adjusted diluted earnings per share (EPS), adjusted operating income, and adjusted EBITDA are non-GAAP financial measures. These non-GAAP financial measures exclude items that are not indicative of our normal operating results and are not comparable to other periods, which may have differing levels of acquired profit in inventory and backlog, restructuring costs, other expense (income), or discrete tax items or none at all. We provide these non-GAAP measures to give investors additional insight into our annual operating performance, especially when compared to periods in which such items had greater or lesser effect or no effect. Non-GAAP financial measures are not meant to be considered superior to or a substitute for the results of operations prepared in accordance with generally accepted accounting principles (GAAP). In addition, the non-GAAP financial measures have limitations associated with their use as compared to the most directly comparable GAAP measures, in that they may be different from, and therefore not comparable to, similar measures used by other companies. We believe that the inclusion of such measures helps investors to gain an understanding of our underlying operating performance and future prospects, consistent with how management measures and forecasts our performance, especially when comparing such results to previous periods or forecasts and to the performance of our competitors. Such measures are also used by us in our financial and operating decision-making and for compensation purposes. We also believe this information is responsive to investors’ requests and gives them an additional measure of our performance.
