By Contrast, Interactions with D.E. Shaw Were Highly Constructive March 1, 2021 The D. E. Shaw Group Welcomes ExxonMobil’s Announcements ExxonMobil’s Recent Announcements Are Significant Positive Developments for All Shareholders The D. E. Shaw group, which manages funds that have been shareholders in Exxon for over 10 years, expressed its support for the addition of Jeffrey Ubben and Michael Angelakis to the Company’s Board of Directors as well as Exxon’s emphasis on cost and capital spending discipline. “We welcome today’s additions to the Exxon Board of Directors. We believe these individuals will bring significant capital markets and capital allocation experience to the boardroom and will provide meaningful value to the Company as it focuses on its investment priorities while navigating the transition to a low-carbon future.” “We also welcome the steps Exxon has taken to identify $6 billion in permanent, structural cost savings, and we believe the Company will be able to identify additional areas to improve its productivity and enhance its cash flow profile during this period of significant industry transition. We are encouraged by these important steps, and we also believe there will be opportunities to reinvest a portion of these cash flows in emerging and high return carbon abatement technologies and strategies. We look forward to continuing our constructive dialogue with Exxon’s management team and Board of Directors.” ExxonMobil has been highly responsive to shareholder feedback 64By Contrast, Interactions with D.E.

Supplemental information IMPORTANT INFORMATION AND ASSUMPTIONS REGARDING CERTAIN FORWARD-LOOKING STATEMENTS. Forward-looking statements contained in this presentation regarding the potential for future earnings, cash flow, margins, ROCE, returns, addressable markets, available cash from operations, operating cash flow, cash operating expenses, net cash margin, and free cash flow are not forecasts of actual future results. These figures are provided to help quantify the potential future results and goals of currently-contemplated management plans and objectives including new project investments, plans to replace natural decline in Upstream production with low-cost volumes, plans to increase sales in our Downstream and Chemical segments and to shift our Downstream product mix toward higher-value products, continued highgrading of ExxonMobil’s portfolio through our ongoing asset management program, both announced and continuous initiatives to improve efficiencies and reduce costs, capital expenditures and cash management, and other efforts within management’s control to impact future results as discussed in this presentation. These figures are intended to quantify for illustrative purposes management’s view of the potentials for these efforts over the time periods shown, calculated on a basis consistent with our internal modelling assumptions for factors such as working capital, as well as factors management does not control, such as interest, differentials, and exchange rates. For all price point comparisons, unless otherwise indicated, we assume $50/bbl Brent crude prices. Unless otherwise specified, crude prices are Brent prices. Except where noted, natural gas prices used are consistent with management’s internal price assumptions for the relevant natural gas markets relative to the crude price for a given case. All crude and natural gas prices for future years are adjusted for inflation from 2021. Downstream and Chemical margins reflect annual historical averages for the 10-year period from 2010—2019 unless otherwise stated. These prices are not intended to reflect management’s forecasts for future prices or the prices we use for internal planning purposes. We have assumed that other factors such as laws and regulations, including tax and environmental laws, and fiscal regimes remain consistent with current conditions for the relevant periods. This presentation does not attempt to model potential COVID-19 outbreaks or recoveries beyond historical pricing. Unless otherwise indicated, asset sales and proceeds are consistent with our internal planning. For future periods, we have assumed Corporate & Financing expenses between $2.1 and $2.7 billion annually. To illustrate future financial capacity, we have used scenarios of Corporate & Financing expenses that reflect the estimated potential debt levels under those scenarios. ExxonMobil-operated emissions, reductions, and avoidance performance data are based on a combination of measured and estimated emissions data using reasonable efforts and collection methods. Calculations are based on industry standards and best practices, including guidance from the American Petroleum Institute (API) and IPIECA. There is uncertainty associated with the emissions, reductions, and avoidance performance data due to variation in the processes and operations, the availability of sufficient data, quality of those data and methodology used for measurement and estimation. Performance data may include rounding. Changes to the performance data may be reported as part of the company’s annual publications as new or updated data and/or emission methodologies become available. Emissions, reductions, and avoidance estimates from non- ExxonMobil operated facilities are also included in the equity data and similarly may be updated as part of the company’s annual publications. ExxonMobil works with industry, including API and IPIECA, to improve emission factors and methodologies. See the Cautionary Statement at the front of this presentation for additional information regarding forward-looking statements. 73Supplemental information IMPORTANT INFORMATION AND ASSUMPTIONS REGARDING CERTAIN FORWARD-LOOKING STATEMENTS.

Supplemental information NON-GAAP AND OTHER MEASURES. With respect to historical periods, reconciliation information is provided in the Frequently Used Terms available on the Investor page of our website at www.exxonmobil.com under the heading News & Resources for certain terms used in this presentation including available cash from operations, operating cash flow, cash operating expense, net cash margin, and free cash flow. For future periods, we are unable to provide a reconciliation of forward-looking non-GAAP or other measures to the most comparable GAAP financial measures because the information needed to reconcile these measures is dependent on future events, many of which are outside management’s control as described above. Additionally, estimating such GAAP measures and providing a meaningful reconciliation consistent with our accounting policies for future periods is extremely difficult and requires a level of precision that is unavailable for these future periods and cannot be accomplished without unreasonable effort. Forward-looking non-GAAP measures are estimated in a manner consistent with the relevant definitions and assumptions noted above. DEFINITIONS AND NON-GAAP FINANCIAL MEASURE RECONCILIATIONS. Available cash from operations. Available cash from operations provides an indication of cash flow available to fund shareholder distributions, capex, and debt reduction and is calculated as the sum of (1) net cash provided by operating activities from the Consolidated statement of cash flows and (2) net cash used in investing activities from the Consolidated statement of cash flows, and (3) capital and exploration expenditures. It includes estimated proceeds from asset sales net of forgone cash flows from divested assets. This measure is useful when evaluating total sources of cash available, including from equity companies, for uses such as capital and exploration expenditures and financing activities, including debt reduction and shareholder distributions. Cash operating expenses (cash Opex, structural efficiencies, or structural reductions). Cash operating expenses are a subset of total operating costs that are stewarded internally to support management’s oversight of spending over time. This measure is useful for investors to understand the Corporation’s efforts to optimize cash through disciplined expense management. For information concerning the calculation and reconciliation of cash operating expenses see the Frequently Used Terms available on the Investors page of our website at www.exxonmobil.com under the heading News & Resources. Compounded Annual Growth Rate (CAGR): represents the consistent rate at which an investment would have grown had the investment compounded at the same rate each year. Free cash flow. Free cash flow is cash flow from operations and asset sales less additions to property, plant and equipment, and additional investments and advances, plus other investing activities, including collection of advances. This measure is useful when evaluating cash available for financing activities, including shareholder distributions, after investment in the business. For information concerning the calculation and reconciliation of free cash flow see the Frequently Used Terms available on the Investors page of our website at www.exxonmobil.com under the heading News & Resources. 74Supplemental information NON-GAAP AND OTHER MEASURES.

Supplemental information DEFINITIONS AND NON-GAAP FINANCIAL MEASURE RECONCILIATIONS, CONTINUED Lower 2°C scenarios. The Intergovernmental Panel on Climate Change (IPCC) published a Special Report on “Global Warming of 1.5°C” and identified 74 scenarios as “Lower 2ºC,” which are pathways limiting peak warming to below 2ºC during the entire 21st century with greater than 66 percent likelihood. Net cash margin ($/bbl input). Net cash margin, following Solomon Associate’s definition, is defined as gross margin at a standard price set for feeds and products, less normalized operating costs on a unit basis, expressed as $/bbl of total input. Operating cash flow. Operating Cash Flow is earnings plus depreciation and depletion, including non-controlling interests and abandonment spend, plus asset sales proceeds. Where applicable, pro-rata equity company earnings are net of depreciation and depletion. This measure is useful when approximating contributions to cash available for investment and financing activities excluding working capital impacts, applied to the Upstream business. Operating costs (Opex). Operating costs are the costs during the period to produce, manufacture, and otherwise prepare the company’s products for sale – including energy, staffing, and maintenance costs. They exclude the cost of raw materials, taxes, and interest expense and are on a before-tax basis. While ExxonMobil’s management is responsible for all revenue and expense elements of net income, operating costs, as defined above, represent the expenses most directly under management’s control, and therefore are useful for investors and ExxonMobil management in evaluating management’s performance. For information concerning the calculation and reconciliation of operating costs see the Frequently Used Terms available on the Investors page of our website at www.exxonmobil.com under the heading News & Resources.

Project. The term “project” as used in this presentation can refer to a variety of different activities and does not necessarily have the same meaning as in any government payment transparency reports. Resources, resource base, and recoverable resources. Along with similar terms, these refer to the total remaining estimated quantities of oil and natural gas that are expected to be ultimately recoverable. ExxonMobil refers to new discoveries and acquisitions of discovered resources as resource additions. The resource base includes quantities of oil and natural gas classified as proved reserves, as well as, quantities that are not yet classified as proved reserves, but that are expected to be ultimately recoverable. The term “resource base” or similar terms is not intended to correspond to SEC definitions such as “probable” or “possible” reserves. The term “in-place” refers to those quantities of oil and natural gas estimated to be contained in known accumulations and includes recoverable and unrecoverable amounts. 75Supplemental information DEFINITIONS AND NON-GAAP FINANCIAL MEASURE RECONCILIATIONS, CONTINUED Lower 2°C scenarios.

Supplemental information DEFINITIONS AND NON-GAAP FINANCIAL MEASURE RECONCILIATIONS, CONTINUED Return on average capital employed (ROCE). ROCE is a performance measure ratio. From the perspective of the business segments, ROCE is annual business segment earnings divided by average business segment capital employed (average of beginning and end-of-year amounts). These segment earnings include ExxonMobil’s share of segment earnings of equity companies, consistent with our capital employed definition, and exclude the cost of financing. The Corporation’s total ROCE is net income attributable to ExxonMobil, excluding the after-tax cost of financing, divided by total corporate average capital employed. The Corporation has consistently applied its ROCE definition for many years and views it as the best measure of historical capital productivity in our capital-intensive, long-term industry, both to evaluate management’s performance and to demonstrate to shareholders that capital has been used wisely over the long term. Additional measures, which are more cash-flow based, are used to make investment decisions. For information concerning the calculation and reconciliation of ROCE see the Frequently Used Terms available on the Investors page of our website at www.exxonmobil.com under the heading News & Resources. Returns, rate of return, IRR. Unless referring specifically to external data, references to returns, rate of return, IRR, and similar terms mean future discounted cash flow returns on future capital investments based on current company estimates. Investment returns exclude prior exploration and acquisition costs. Stated Policies Scenario (STEPS). STEPS is an IEA scenario in their World Energy Outlook 2020 based on today’s policy settings and an assumption that the COVID-19 pandemic is brought under control in 2021. Total Addressable Market (TAM). Refers to the size of the total market revenue of a particular product or service Total Shareholder Return (TSR). Measures the change in value of an investment in stock over a specified period of time, assuming dividend reinvestment. TSR is subject to many different variables, including factors beyond the control of management. 76Supplemental information DEFINITIONS AND NON-GAAP FINANCIAL MEASURE RECONCILIATIONS, CONTINUED Return on average capital employed (ROCE).
