NYSE: “OMN” Cautionary Statements › Forward-Looking Statements Third Quarter 2017INVESTOR PRESENTATION |2 This presentation includes descriptions of OMNOVA's current business, operations, assets and other matters affecting the Company as well as "forward-looking statements" as defined by federal securities laws. All forward-looking statements by the Company, including verbal statements, are intended to qualify for the protections afforded forward-looking statements under the Private Securities Litigation Reform Act of 1995. Forward-looking statements reflect management's current expectation, judgment, belief, assumption, estimate or forecast about future events, circumstances or results and may address business conditions and prospects, strategy, capital structure, debt and cash levels, sales, profits, earnings, markets, products, technology, operations, customers, raw materials, claims and litigation, financial condition, and accounting policies among other matters. Words such as, but not limited to, "will," "may," "should," "projects," "forecasts," "seeks," "believes," "expects," "anticipates," "estimates," "intends," "plans," "targets," "optimistic," "likely," "would," "could," "committed," and similar expressions or phrases identify forward-looking statements. All descriptions of OMNOVA's current business, operations and assets, as well as all forward-looking statements, involve risks and uncertainties. Many risks and uncertainties are inherent in business generally. Other risks and uncertainties are more specific to the Company's businesses and strategy, or to any new businesses the Company may enter into or acquire. There also may be risks and uncertainties not currently known to the Company. The occurrence of any such risks and uncertainties and the impact of such occurrences is often not predictable or within the Company's control. Such impacts could adversely affect the Company's business, operations or assets as well as the Company's results and the value of your investment in the Company. In some cases, such impact could be material. Certain risks and uncertainties facing the Company are described below or in the Company's Quarterly Report on Form 10-Q and Annual Report and the value of your investment in the Company on Form 10-K. All written and verbal descriptions of OMNOVA's current business, operations and assets and all forward-looking statements attributable to the Company or any person acting on the Company's behalf are expressly qualified in their entirety by the risks, uncertainties, and cautionary statements contained or referenced herein. All such descriptions and any forward-looking statement speak only as of the date on which such description or statement is made, and the Company undertakes no obligation, and specifically declines any obligation, other than that imposed by law, to publicly update or revise any such description or forward-looking statements whether as a result of new information, future events or otherwise. The Company's actual results and the value of your investment in OMNOVA may differ, perhaps materially, from expectations due to a number of risks and uncertainties including, but not limited to: (1) the Company's exposure to general economic, business, and industry conditions; (2) the risk of doing business in foreign countries and markets; (3) changes in raw material prices and availability; (4) the highly competitive markets the Company serves; (5) extraordinary events such as natural disasters, political disruptions, terrorist attacks and acts of war; (6) extensive and increasing United States and international governmental regulation, including environmental, health and safety regulations; (7) the Company's failure to protect its intellectual property or defend itself from intellectual property claims; (8) claims and litigation; (9) changes in accounting policies, standards, and interpretations; (10) the actions of activist shareholders; (11) the Company's inability to achieve, or achieve in a timely manner, the objectives and benefits of cost reduction initiatives; (12) the Company's ability to develop and commercialize new products at competitive prices; (13) the concentration of certain of OMNOVA's businesses and market segments among several large customers; (14) the creditworthiness of the Company's customers; (15) the failure of a joint venture partner to meet its commitments; (16) the Company's ability to identify and complete strategic transactions; (17) the Company's ability to successfully integrate acquired companies; (18) unanticipated capital expenditures; (19) risks associated with the use, production, storage, and transportation of chemicals; (20) information system failures and breaches in security; (21) continued increases in healthcare costs; (22) the Company's ability to retain or attract key employees; (23) the Company's ability to renew collective bargaining agreements with employees on acceptable terms and the risk of work stoppages; (24) the Company's contribution obligations under its U.S. pension plan; (25) the Company's reliance on foreign financial institutions to hold some of its funds; (26) the effect of goodwill impairment charges; (27) the volatility in the market price of the Company's common shares; (28) the Company's substantial debt position; (29) the decision to incur additional debt; (30) the operational and financial restrictions contained in the Company's indenture; (31) a default under the Company's term loan or revolving credit facility; (32) the Company's ability to generate sufficient cash to service its outstanding debt; and (33) the ability of the Company's subsidiaries to provide cash in order to pay a debt. OMNOVA Solutions provides greater detail regarding these risks and uncertainties in its 2016 Form 10-K and subsequent filings, which are available online at www.omnova.com and www.sec.gov.

NYSE: “OMN” Appendix – Non-GAAP Financial Measures This presentation includes Adjusted Segment Operating Profit, Adjusted Segment EBITDA, Adjusted Income from Continuing Operations Before Income Taxes, Adjusted Consolidated EBITDA and other financial measures which are Non-GAAP financial measures as defined by the Securities and Exchange Commission. OMNOVA’s Adjusted Segment Operating Profit is calculated as Segment Operating Profit (Loss) less restructuring and severance expenses, asset impairments and other items. Adjusted Segment EBITDA is calculated as Adjusted Segment Operating Profit less depreciation and amortization expense less accelerated depreciation. OMNOVA’s Adjusted Income from Continuing Operations Before Income Taxes is calculated as Adjusted Segment Operating Profit less corporate expenses, interest, restructuring and severance, asset impairments and other items. OMNOVA’s Adjusted EBITDA is calculated as Adjusted Income from Continuing Operations Before Income Taxes less interest expense less debt premium and depreciation and amortization expense less accelerated depreciation. Adjusted Segment Operating Profit and Adjusted Segment and/or Consolidated EBITDA and the other financial measures (collectively, the “Non-GAAP financial measures”) are not calculated in the same manner by all companies and, accordingly, are not necessarily comparable to similarly titled measures of other companies and may not be appropriate measures for comparing performance relative to other companies. The Non-GAAP financial measures should not be construed as indicators of the Company’s operating performance or liquidity and should not be considered in isolation from or as a substitute for net income (loss), cash flows from operations or cash flow data, which are all prepared in accordance with GAAP. The Non-GAAP financial measures are not intended to represent, and should not be considered more meaningful than or as an alternative to, measures of operating performance as determined in accordance with GAAP. Management believes that presenting this information is useful to investors because these measures are commonly used as analytical indicators to evaluate performance and by management to allocate resources. Set forth in the appendices are the reconciliations of these Non-GAAP financial measures to their most directly comparable GAAP financial measure. All appendix results are pro forma reflecting continuing business excluding the sale of the global wallcovering business. Third Quarter 2017INVESTOR PRESENTATION |30
