2 Forward-Looking Statements This presentation and remarks made as part of this presentation contain “forward-looking statements,” which include information concerning the company’s plans, objectives, goals, strategies, future revenues or performance, capital expenditures, financing needs and other information that is not historical information. When used in this presentation and related remarks, the words “outlook,” “forecast,” “estimates,” “expects,” “anticipates,” “projects,” “plans,” “intends,” “believes,” “may,” “can,” “could,” “might,” “will” and variations of such words or similar expressions are intended to identify forward-looking statements. All forward-looking statements are based upon current expectations and beliefs and various assumptions. There can be no assurance that the company will realize these expectations or that these beliefs will prove correct. There are a number of risks and uncertainties that could cause actual results to differ materially from the results expressed or implied in the forward-looking statements contained in this presentation and related remarks. These risks and uncertainties include, among other things: changes in general economic, business, political and regulatory conditions in the countries or regions in which we operate; the length and depth of product and industry business cycles, particularly in the automotive, electrical, textiles, electronics and construction industries; changes in the price and availability of raw materials, particularly changes in the demand for, supply of, and market prices of ethylene, methanol, natural gas, wood pulp and fuel oil and the prices for electricity and other energy sources; the ability to pass increases in raw material prices on to customers or otherwise improve margins through price increases; the ability to maintain plant utilization rates and to implement planned capacity additions and expansions; the ability to improve productivity by implementing technological improvements to existing plants; increased price competition and the introduction of competing products by other companies; market acceptance of our technology; the ability to obtain governmental approvals and to construct facilities on terms and schedules acceptable to the company; changes in the degree of intellectual property and other legal protection afforded to our products or technology, or the theft of such intellectual property; compliance and other costs and potential disruption or interruption of production or operations due to accidents, cyber security incidents, terrorism or political unrest or other unforeseen events or delays in construction or operation of facilities, including as a result of geopolitical conditions, including the occurrence of acts of war or terrorist incidents, or as a result of weather or natural disasters; potential liability for remedial actions and increased costs under existing or future environmental regulations, including those relating to climate change; potential liability resulting from pending or future litigation, or from changes in the laws, regulations or policies of governments or other governmental activities in the countries in which we operate; changes in currency exchange rates and interest rates; our level of indebtedness, which could diminish our ability to raise additional capital to fund operations or limit our ability to react to changes in the economy or the chemicals industry; and various other factors discussed from time to time in the company’s filings with the Securities and Exchange Commission. In addition to the risks and uncertainties identified above, the following risks and uncertainties, among others, could cause the company’s actual results regarding its initiatives involving the use of advanced technology for the production of ethanol for chemical applications and other uses to differ materially from the results expressed or implied in these materials: the impact of technological developments and competition; our ability to obtain licenses of, or other access to, alternative ethanol production processes on attractive terms; unanticipated operational or commercialization difficulties, including failure of facilities or processes to operate in accordance with specifications or expectations; the cost and availability of capital necessary to fund plant construction and expansion; the unavailability of required materials and equipment; changes in the price and availability of commodities and supplies; the ability to achieve the anticipated cost structure; the growth in demand for products produced from our technology in certain industries or geographic regions; the adoption of new or different industry or regulatory standards; and the ability of third parties, including our commercial partners or suppliers, to comply with their commitments to us. Forward-looking statements speak only as of the date on which they are made, and the company undertakes no obligation to update any forward-looking statement to reflect events or circumstances after the date on which it is made or to reflect the occurrence of anticipated or unanticipated events or circumstances. Results Unaudited The results in this presentation, together with the adjustments made to present the results on a comparable basis, have not been audited and are based on internal financial data furnished to management. Quarterly and full fiscal year results should not be taken as an indication of the results of operations to be reported for any subsequent period or for the full fiscal year.

3 Non-US GAAP Financial Information Reconciliation of Non-U.S. GAAP Measures to U.S. GAAP This presentation reflects the following performance measures: operating EBITDA, business operating EBITDA, affiliate EBITDA and proportional affiliate EBITDA, adjusted earnings per share, net debt, and adjusted free cash flow as non-U.S. GAAP measures. These measurements are not recognized in accordance with U.S. GAAP and should not be viewed as an alternative to U.S. GAAP measures of performance. The most directly comparable financial measure presented in accordance with U.S. GAAP in our consolidated financial statements for operating EBITDA and business operating EBITDA is net income; for proportional affiliate EBITDA is equity in net earnings of affiliates; for affiliate EBITDA is operating profit; for adjusted earnings per share is earnings per common share-diluted; for net debt is total debt; and for adjusted free cash flow is cash flow from operations. Use of Non-U.S. GAAP Financial Information ► Operating EBITDA, a measure used by management to measure performance, is defined by the company as net earnings minus interest income plus loss (earnings) from discontinued operations, interest expense, income taxes and depreciation and amortization, and further adjusted for Other Charges and Adjustments as described in the Appendix. We may provide guidance on operating EBITDA and are unable to reconcile forecasted operating EBITDA to a U.S. GAAP financial measure because a forecast of Other Charges and Adjustments is not practical. ► Business operating EBITDA, a measure used by management to measure performance of its internal operations, is defined by the company as net earnings minus interest income plus loss (earnings) from discontinued operations, interest expense, income taxes and depreciation and amortization, and further adjusted for Other Charges and Adjustments as described in the Appendix, less equity in net earnings of affiliates, dividend income from cost investments and other (income) expense. This reflects the operating results of the company’s operations without regard to its equity and cost investments. The company believes that investors should consider business operating EBITDA when evaluating the company’s internal operations. ► Affiliate EBITDA is defined by the company as operating profit plus the depreciation and amortization of its equity affiliates. Proportional affiliate EBITDA, a measure used by management to measure performance of its equity investments, is defined by the company as the proportional operating profit plus the proportional depreciation and amortization of its equity investments. The company has determined that it does not have sufficient ownership for operating control of these investments to consider their results on a consolidated basis. We believe that investors should consider proportional affiliate EBITDA as an additional measure of operating results. ► Adjusted earnings per share is a measure used by management to measure performance. It is defined by the company as net earnings (loss) available to common shareholders plus preferred dividends, adjusted for other charges and adjustments, and divided by the number of basic common shares, diluted preferred shares, and options valued using the treasury method. We may provide guidance on an adjusted earnings per share basis and are unable to reconcile forecasted adjusted earnings per share to a U.S. GAAP financial measure without unreasonable effort because a forecast of Other Items is not practical. We believe that the presentation of this non-U.S. GAAP measure provides useful information to management and investors regarding various financial and business trends relating to our financial condition and results of operations, and that when U.S. GAAP information is viewed in conjunction with non-U.S. GAAP information, investors are provided with a more meaningful understanding of our ongoing operating performance. Note: The income tax rate used for adjusted earnings per share approximates the midpoint in a range of forecasted tax rates for the year. This range may include certain partial or full- year forecasted tax opportunities, where applicable, and specifically excludes changes in uncertain tax positions, discrete items and other material items adjusted out of our U.S. GAAP earnings for adjusted earnings per share purposes, and changes in management's assessments regarding the ability to realize deferred tax assets. We analyze this rate quarterly and adjust if there is a material change in the range of forecasted tax rates; an updated forecast would not necessarily result in a change to our tax rate used for adjusted earnings per share. The adjusted tax rate is an estimate and may differ from the tax rate used for U.S. GAAP reporting in any given reporting period. It is not practical to reconcile our prospective adjusted tax rate to the actual U.S. GAAP tax rate in any given future period. ► Net debt is defined by the company as total debt less cash and cash equivalents. We believe that the presentation of this non-U.S. GAAP measure provides useful information to management and investors regarding changes to the company’s capital structure. Our management and credit analysts use net debt to evaluate the company's capital structure and assess credit quality. Proportional net debt is defined as our proportionate share of our affiliates’ net debt. ► Adjusted free cash flow is defined by the company as cash flow from operations less other productive asset purchases, operating cash from discontinued operations and certain other charges and adjustments. We believe that the presentation of this non-U.S. GAAP measure provides useful information to management and investors regarding changes to the company's cash flow. Our management and credit analysts use adjusted free cash flow to evaluate the company's liquidity and assess credit quality. Although we use adjusted free cash flow as a financial measure to assess the performance of our business, the use of adjusted free cash flow has important limitations, including that adjusted free cash flow does not reflect the cash requirements necessary to service our indebtedness, lease obligations, unconditional purchase obligations or pension and postretirement funding obligations.
