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, and cash operating expenses 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. 20Supplemental 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 cash operating expense. 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. 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. 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. 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. Peers / Peer average. Proxy industry peers are Chevron (NYSE: CVX), Royal Dutch Shell (LON: RDSA), Total (EPA: FP), BP (LON: BP) 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. 21Supplemental information NON-GAAP AND OTHER MEASURES.

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).
