Appendix

113 Safe Harbor Cautionary Statement about Forward-Looking Statements Certain statements in this presentation are “forward-looking statements” within the meaning of the federal securities laws, including Section 27A of the Securities Act of 1933, as amended, and Section 21E of the Securities Exchange Act of 1934, as amended. Such statements often address expected future business and financial performance, financial condition, and other matters, and often contain words or phrases such as “anticipate,” “believe,” “estimate,” “expect,” “intend,” “may,” “opportunity,” “outlook,” “plan,” “project,” “seek,” “should,” “strategy,” “target,” “will,” “will be,” “will continue,” “will likely result,” “would” and similar expressions, and variations or negatives of these words or phrases. Forward-looking statements are based on current assumptions and expectations of future events that are subject to risks, uncertainties and other factors that are beyond Dow’s control, which may cause actual results to differ materially from those projected, anticipated or implied in the forward-looking statements and speak only as of the date the statements were made. These factors include, but are not limited to: sales of Dow’s products; Dow’s expenses, future revenues and profitability; the continuing global and regional economic impacts of the coronavirus disease 2019 (“COVID-19”) pandemic and other public health-related risks and events on Dow’s business; capital requirements and need for and availability of financing; unexpected barriers in the development of technology, including with respect to Dow’s contemplated capital and operating projects; Dow’s ability to realize its commitment to carbon neutrality on the contemplated timeframe; size of the markets for Dow’s products and services and ability to compete in such markets; failure to develop and market new products and optimally manage product life cycles; the rate and degree of market acceptance of Dow’s products; significant litigation and environmental matters and related contingencies and unexpected expenses; the success of competing technologies that are or may become available; the ability to protect Dow’s intellectual property in the United States and abroad; developments related to contemplated restructuring activities and proposed divestitures or acquisitions such as workforce reduction, manufacturing facility and/or asset closure and related exit and disposal activities, and the benefits and costs associated with each of the foregoing; fluctuations in energy and raw material prices; management of process safety and product stewardship; changes in relationships with Dow’s significant customers and suppliers; changes in consumer preferences and demand; changes in laws and regulations, political conditions or industry development; global economic and capital markets conditions, such as inflation, market uncertainty, interest and currency exchange rates, and equity and commodity prices; business or supply disruptions; security threats, such as acts of sabotage, terrorism or war; weather events and natural disasters; and disruptions in Dow’s information technology networks and systems. Risks related to Dow’s separation from DowDuPont Inc. include, but are not limited to: (i) Dow’s inability to achieve some or all of the benefits that it expects to receive from the separation from DowDuPont Inc.; (ii) certain tax risks associated with the separation; (iii) the failure of Dow’s pro forma financial information to be a reliable indicator of Dow’s future results; (iv) non-compete restrictions under the separation agreement; (v) receipt of less favorable terms in the commercial agreements Dow entered into with DuPont de Nemours, Inc. (“DuPont”) and Corteva, Inc. (“Corteva”), including restrictions under intellectual property cross-license agreements, than Dow would have received from an unaffiliated third party; and (vi) Dow’s obligation to indemnify DuPont and/or Corteva for certain liabilities. Where, in any forward-looking statement, an expectation or belief as to future results or events is expressed, such expectation or belief is based on the current plans and expectations of management and expressed in good faith and believed to have a reasonable basis, but there can be no assurance that the expectation or belief will result or be achieved or accomplished. A detailed discussion of principal risks and uncertainties which may cause actual results and events to differ materially from such forward-looking statements is included in the section titled “Risk Factors” contained in the Company’s Annual Report on Form 10-K for the year ended December 31, 2020. These are not the only risks and uncertainties that Dow faces. There may be other risks and uncertainties that Dow is unable to identify at this time or that Dow does not currently expect to have a material impact on its business. If any of those risks or uncertainties develops into an actual event, it could have a material adverse effect on Dow’s business. Dow assumes no obligation to update or revise publicly any forward-looking statements whether because of new information, future events, or otherwise, except as required by securities and other applicable laws.

Non-GAAP Financial Measures This presentation includes information that does not conform to U.S. GAAP and are considered non-GAAP measures. Management uses these measures internally for planning, forecasting and evaluating the performance of the Company's segments, including allocating resources. Dow's management believes that these non-GAAP measures best reflect the ongoing performance of the Company during the periods presented and provide more relevant and meaningful information to investors as they provide insight with respect to ongoing operating results of the Company and a more useful comparison of year-over-year results. These non-GAAP measures supplement the Company's U.S. GAAP disclosures and should not be viewed as alternatives to U.S. GAAP measures of performance. Furthermore, such non-GAAP measures may not be consistent with similar measures provided or used by other companies. Dow does not provide forward-looking U.S. GAAP financial measures or a reconciliation of forward-looking non-GAAP financial measures to the most comparable U.S. GAAP financial measures on a forward-looking basis because the Company is unable to predict with reasonable certainty the ultimate outcome of pending litigation, unusual gains and losses, foreign currency exchange gains or losses and potential future asset impairments, as well as discrete taxable events, without unreasonable effort. These items are uncertain, depend on various factors, and could have a material impact on U.S. GAAP results for the guidance period. General Comments Unless otherwise specified, all financial measures in this presentation, where applicable, exclude significant items.
