Cautionary Statement about Forward-Looking Statements

This presentation contains "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. In this context, forward-looking statements often address expected future business and financial performance, financial condition, and other matters, and often contain words 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. Forward-looking statements are based on current expectations and assumptions that are subject to risks and uncertainties which may cause actual results to differ materially from the forward-looking statements.

Forward-looking statements include, but are not limited to: expectations as to future sales of Dow's products; the ability to protect Dow's intellectual property in the United States and abroad; estimates regarding Dow's capital requirements and need for and availability of financing; estimates of Dow's expenses, future revenues and profitability; estimates of the size of the markets for Dow's products and services and Dow's ability to compete in such markets; expectations related to the rate and degree of market acceptance of Dow's products; the outcome of certain Dow contingencies, such as litigation and environmental matters; estimates of the success of competing technologies that may become available; the continuing global and regional economic impacts of the coronavirus disease 2019 ("COVID-19") pandemic and crude oil supply and price volatility; estimates regarding benefits achieved through contemplated restructuring activities, such as workforce reduction, exit and disposal activities; and expectations regarding the benefits and costs associated with each of the foregoing.

Forward-looking statements by their nature address matters that are, to different degrees, uncertain. Forward-looking statements are based on certain assumptions and expectations of future events which may not be realized and speak only as of the date the statements were made. In addition, forward-looking statements also involve risks, uncertainties and other factors that are beyond Dow's control that could cause Dow's actual results to differ materially from those projected, anticipated or implied in the forward-looking statements. These factors include, but are not limited to: fluctuations in energy and raw material prices; failure to develop and market new products and optimally manage product life cycles; significant litigation and environmental matters; failure to appropriately manage process safety and product stewardship issues; changes in laws and regulations or political conditions; 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; ability to protect, defend and enforce Dow's intellectual property rights; increased competition; changes in relationships with Dow's significant customers and suppliers; unanticipated expenses such as litigation or legal settlement expenses; unanticipated business disruptions; Dow's ability to predict, identify and interpret changes in consumer preferences and demand; Dow's ability to complete proposed divestitures or acquisitions; Dow's ability to realize the expected benefits of acquisitions if they are completed; the availability of financing to Dow in the future and the terms and conditions of such financing; disruptions in Dow's information technology networks and systems; the continuing risks related to the COVID-19 pandemic and crude oil supply and price volatility; and Dow's ability to realize the expected benefits of restructuring activities if they are approved and completed. Additionally, 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.

Risks related to achieving the anticipated benefits of Dow's separation from DowDuPont include, but are not limited to, a number of conditions outside the control of Dow, including risks related to: (i) Dow's inability to achieve some or all of the benefits that it expects to receive from the separation from DowDuPont; (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;

1. Dow's inability to receive third-party consents required under the separation agreement; (v) non-compete restrictions under the separation agreement; (vi) receipt of less favorable terms in the commercial agreements Dow entered into with DuPont and Corteva, Inc. ("Corteva"), including restrictions under intellectual property cross-license agreements, than Dow would have received from an unaffiliated third party; and (vii) 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. For a more detailed discussion of Dow's risks and uncertainties, see Part I, Item 1A of the Dow Inc. and TDCC combined Annual Report on Form 10-K for the year ended December 31, 2019 and Part II, Item 1A of the Quarterly Report on Form 10-Q for the quarterly period ended June 30, 2020. Dow Inc. and TDCC assume 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.

GENERAL COMMENTS

Separation from DowDuPont

On April 1, 2019, DowDuPont Inc. ("DowDuPont" and effective June 3, 2019, n/k/a DuPont de Nemours, Inc. or "DuPont") completed the separation of its materials science business and Dow Inc. became the direct parent company of The Dow Chemical Company and its consolidated subsidiaries ("TDCC" and together with Dow Inc., "Dow" or the "Company"), owning all of the outstanding common shares of TDCC. For filings related to the period commencing April 1, 2019 and thereafter, TDCC was deemed the predecessor to Dow Inc., and the historical results of TDCC are deemed the historical results of Dow Inc. for periods prior to and including March 31, 2019. The information in this report reflects the results of Dow and its consolidated subsidiaries, after giving effect to the distribution to DowDuPont of TDCC's agricultural sciences business ("AgCo") and specialty products business ("SpecCo") and the receipt of E. I. du Pont de Nemours and Company and its consolidated subsidiaries' ("Historical DuPont") ethylene and ethylene copolymers business (other than its ethylene acrylic elastomers business) ("ECP"). The separation was contemplated by the merger of equals transaction effective August 31, 2017, under the Agreement and Plan of Merger, dated as of December 11, 2015, as amended on March 31, 2017. TDCC and Historical DuPont each merged with subsidiaries of DowDuPont and, as a result, TDCC and Historical DuPont became subsidiaries of DowDuPont (the "Merger"). Subsequent to the Merger, TDCC and Historical DuPont engaged in a series of internal reorganization and realignment steps to realign their businesses into three subgroups: agriculture, materials science and specialty products. Dow Inc. was formed as a wholly owned subsidiary of DowDuPont to serve as the holding company for the materials science business.
