Exhibit 99.3 Fourth Quarter and Fiscal Year 2018 Business Review February 14, 2019

Forward-Looking Statements The following constitutes a “Safe Harbor” statement under the Private Securities Litigation Reform Act of 1995: This presentation contains forward-looking statements that involve a number of risks and uncertainties, including forward-looking statements about our future financial and operating performance, demand for our products, and economic and industry outlook. These forward-looking statements represent Kadant’s expectations as of the date of this presentation. We undertake no obligation to publicly update any forward-looking statement, whether as a result of new information, future events, or otherwise. These forward-looking statements are subject to known and unknown risks and uncertainties that may cause our actual results to differ materially from these forward-looking statements as a result of various important factors, including those set forth under the heading "Risk Factors" in Kadant’s annual report on Form 10-K for the year ended December 30, 2017 and subsequent filings with the Securities and Exchange Commission. These include risks and uncertainties relating to adverse changes in global and local economic conditions; the variability and difficulty in accurately predicting revenues from large capital equipment and systems projects; our customers’ ability to obtain financing for capital equipment projects; the variability and uncertainties in sales of capital equipment in China; international sales and operations; the oriented strand board market and levels of residential construction activity; development and use of digital media; currency fluctuations; price increases or shortages of raw materials; dependence on certain suppliers; our acquisition strategy; failure of our information systems or breaches of data security; changes in government regulations and policies and compliance with laws; our internal growth strategy; competition; soundness of suppliers and customers; changes in our tax provision or exposure to additional tax liabilities; our ability to successfully manage our manufacturing operations; disruption in production; future restructurings; economic conditions and regulatory changes caused by the United Kingdom’s likely exit from the European Union; our debt obligations; restrictions in our credit agreement; loss of key personnel; protection of patents and proprietary rights; fluctuations in our share price; soundness of financial institutions; environmental laws and regulations; anti- takeover provisions; and reliance on third-party research.

Use of Non-GAAP Financial Measures In addition to the financial measures prepared in accordance with U.S. generally accepted accounting principles (GAAP), we use certain non-GAAP financial measures, including increases or decreases in revenues that exclude the effect of acquisitions and foreign currency translation, adjusted operating income, adjusted net income, adjusted diluted EPS, adjusted earnings before interest, taxes, depreciation, and amortization (adjusted EBITDA), adjusted EBITDA margin, and free cash flow. A reconciliation of those numbers to the most directly comparable GAAP financial measures is shown in the appendix to this presentation and in our 2018 fourth quarter earnings press release issued February 13, 2019, which is available in the Investors section of our website at www.kadant.com under the heading Press Releases. We believe these non-GAAP financial measures, when taken together with the corresponding GAAP financial measures, provide meaningful supplemental information regarding our performance by excluding certain items that may not be indicative of our core business, operating results, or future outlook. We believe the inclusion of such measures helps investors 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. The non-GAAP financial measures included in this presentation are not meant to be considered superior to or a substitute for the results of operations prepared in accordance with GAAP. In addition, the non-GAAP financial measures included in this presentation 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.
