2© 2017 Knoll Inc. Forward-Looking Statements/Non-GAAP Measures This presentation includes forward-looking statements within the meaning of Section 27A of the Securities Act of 1933, as amended, and Section 21E of the Securities Exchange Act of 1934, as amended. All statements regarding Knoll, Inc.’s expected future financial position, results of operations, cash flows, business strategy, budgets, projected costs, capital expenditures, products, competitive positions, growth opportunities, plans and objectives of management for future operations, as well as statements that include words such as "anticipate," "if," "believe," "plan," "goals," "estimate," "expect," "intend," "may," "could," "should," "will," and other similar expressions are forward-looking statements. This includes, without limitation, our statements and expectations regarding any current or future recovery in our industry, our publicly announced plans for increased capital and investment spending to achieve our long-term revenue and profitability growth goals, our expectations with respect to our diversification strategy, our future performance in relation to our industry (BIFMA), and our expectations with respect to leverage. Such forward-looking statements are inherently uncertain, and readers must recognize that actual results may differ materially from the expectations of Knoll management. Knoll does not undertake a duty to update such forward- looking statements. Factors that may cause actual results to differ materially from those in the forward-looking statements include corporate spending and service-sector employment, price competition, acceptance of Knoll’s new products, the pricing and availability of raw materials and components, foreign exchange rates, transportation costs, demand for high quality, well designed furniture solutions, changes in the competitive marketplace, changes in trends in the market for furniture and coverings, the financial strength and stability of our suppliers, customers and dealers, access to capital, our success in designing and implementing our new enterprise resource planning system, our ability to successfully integrate acquired businesses, and other risks identified in Knoll’s Annual Report on Form 10-K and other filings with the Securities and Exchange Commission, as well as other cautionary statements that are made from time-to-time in Knoll’s public communications. Many of these factors are outside of Knoll’s control. This presentation also includes certain non-GAAP financial measures. A “non-GAAP financial measure” is a numerical measure of a company’s financial performance that excludes or includes amounts so as to be different than the most directly comparable measure calculated and presented in accordance with U.S. generally accepted accounting principles (“GAAP”). We present Non-GAAP measures because we consider them to be important supplemental measures of our performance and believe them to be useful to display ongoing results from operations distinct from items that are infrequent or not indicative of our operating performance. We have provided reconciliations of these non-GAAP financial measures to the most directly comparable GAAP measure in the presentation below. These non-GAAP measures are not indicators of our financial performance under GAAP and should not be considered as an alternative to the applicable GAAP measure. These non-GAAP measures have limitations as analytical tools, and you should not consider them in isolation or as a substitute for analysis of our results as reported under GAAP. Our presentation of these non-GAAP measures should not be construed as an inference that our future results will be unaffected by unusual or infrequent items.
