in a Changing Industry and World

Engine No. 1’s Nominees Have a Diverse Set of Experiences in Successful, Global Energy Operations and Decades of Leading Value-Creating Transformations in the Energy Industry

Urges ExxonMobil Shareholders to Vote the WHITE Proxy Card TODAY “FOR ALL” of

Engine No. 1’s Highly Qualified, Independent Nominees

SAN FRANCISCO – April 26, 2021 – Engine No. 1, which has nominated four highly qualified, independent director candidates to the Exxon Mobil Corporation (NYSE: XOM) (“ExxonMobil” or the “Company”) Board of Directors (the “Board”), today released an in-depth presentation to ExxonMobil shareholders detailing the need for change at ExxonMobil to protect and enhance long-term shareholder value in a changing industry and world. Engine No. 1 encourages ExxonMobil shareholders to review the facts set forth in its presentation so they can make an informed decision at the Company’s 2021 Annual Meeting regarding the future of the Company and their investment.

Engine No. 1’s investor presentation can be found here.

Key issues under the current Board examined in the presentation include:

· Issue #1: Failure to Position ExxonMobil for Long-Term Value Creation

· Issue #2: Rhetoric Does Not Address Long-Term Business Risk from Emissions

· Issue #3: Lack of Capital Allocation Discipline

· Issue #4: Little Reason to Trust Newfound Spending Discipline

· Issue #5: Lack of Successful and Transformative Energy Experience on the Board

· Issue #6: Misaligned Incentives

Engine No. 1’s director candidates add a highly relevant, unique and complementary set of skills to the Board, and, as directors, would help to address the fundamental issues at the Company by bringing to bear their collective experiences in value-creating transformational change in the energy sector.

PART I: EXECUTIVE SUMMARY The Need for Change at ExxonMobil 5

The industry is evolving, and so must ExxonMobil O il and gas companies face significant long - term challenges. Declining long - term returns and lower capital productivity for non - state oil and gas companies Growing long - term demand uncertainty due to advancements in low and no - carbon technologies Growing long - term business model risk as pressure increases for countries to lower carbon emissions • ExxonMobil has significantly underperformed and has failed to adjust its strategy to enhance long - term value • A focus on chasing production growth over value has resulted in an undisciplined capital allocation strategy and has destroyed value even during periods of higher oil and gas prices • A refusal to accept that fossil fuel demand may decline in decades to come has led to a failure to take even initial steps towards evolution, and to obfuscating rather than addressing long - term business risk • A lack of successful and transformative energy experience on the Board has left ExxonMobil unprepared and threatens continued long - term value destruction 6

ExxonMobil has pursued the most aggressive spending plans in the industry to chase production growth • Despite investor demand for spending discipline, for years ExxonMobil has pursued aggressive capital expenditure plans to chase production growth • This strategy has contributed to significant share price underperformance in recent years and left ExxonMobil far more exposed than peers to demand declines • While in the face of a deteriorating balance sheet and investor pressure ExxonMobil reduced its near - term spending plans, its long - term model remains unchanged “Chevron now targets free cash flow, returns and constrained emissions, while Exxon is sticking to the traditional oil major mega - projects tactic.” Bloomberg, March 23, 2021 “[ExxonMobil] is sticking with plans to increase crude production in the coming years …” Financial Times, March 1, 2021 “Analysts say a quest for fast oil - production growth and an addiction to risky, high - cost projects have hobbled the company in recent years. Yet Exxon’s response has been to double down on oil and gas, plotting another huge surge in output. As rivals fret about peaking oil demand and start trying to navigate a global energy transition away from fossil fuels to cleaner energy, Exxon is making a huge bet on oil’s future.” Financial Times, October 28, 2020 9 Quote Source: Derek Brower (Oct. 28, 2020).

ExxonMobil has been funding spending on low - return projects by taking on large amounts of debt • While its balance sheet once had almost zero net debt, today ExxonMobil has the most debt in its history, increasing over $80 billion in the last 12 years, and since 2016 has had three debt ratings downgrades by S&P (including two pre - COVID) • Given financial pressure, ExxonMobil last year suspended its employee 401(k) matching program and utilized enhanced “performance reviews” to conduct layoffs Chart Source: ExxonMobil 10 - Ks & Bloomberg.

ExxonMobil still has no credible plan to protect value in an energy transition … • ExxonMobil is world’s 5th largest producer of greenhouse gas (GHG) emissions (after coal from China, Saudi Aramco, Gazprom, and Nat’l Iranian Oil) • This is an existential business risk given that 2/3 of emissions come from countries that have pledged to reach net zero emissions by 2050 • Any diversification strategy must be profitable over the long - term to be sustainable.

… yet rather than changing its long - term strategy, ExxonMobil is trying to change the subject • In the past ExxonMobil dismissed total emissions reduction targets as a “beauty competition” • Now it claims its emissions reduction targets are “consistent” with the Paris Agreement • However, in setting such targets ExxonMobil first excludes ~90% of its emissions, by excluding all Scope 3 emissions (from burning fossil fuels) and Scope 1 and 2 emissions (from producing fossil fuels) from non - operated assets • Likewise, while ExxonMobil touts its efforts in areas like carbon capture and biofuels, such efforts have mostly generated advertising Chart Source: ExxonMobil Energy and Carbon Summary 2020 and 2021.

ExxonMobil paints an unrealistic picture of the likelihood that carbon capture will obviate the need for change ... • It is true that the IPCC and IEA have said that carbon capture is critical for a 2 ƒ C pathway, but they have made clear that it is not a substitute for dramatically reducing conventional fossil fuel usage • While ExxonMobil has trumpeted carbon capture, its actual carbon captured has changed little • All of the world’s existing carbon capture projects can capture less than 0.1% of global emissions • Projects to reduce Scope 3 emissions are incredibly costly and prone to failure, and heavily dependent upon government subsidies ExxonMobil’s Carbon Capture of 6.8Mn tons is <1% of its Annual Emissions of 690Mn tons of CO2 Quote Source: IEA.

… and fails to accurately portray the relevance of its own carbon capture capabilities • ExxonMobil claims to be the “global leader” in carbon capture, yet most of this is the necessary separation of CO 2 that naturally occurs during the production of methane (the key ingredient in natural gas), which is captured versus vented • This reduces Scope 1 and 2 emissions intensity, not the far larger Scope 3 emissions from burning natural gas, and total emissions rise with production growth even if emissions intensity falls • Also, much of the CO 2 captured is injected into the ground to loosen hard to reach oil, thus increasing total emissions • New “Low Carbon Solutions” business mostly a patchwork of existing projects Sources: Kevin Crowley (Feb 1, 2021).

PART II: A CLOSER LOOK AT THE ISSUES Issue #1 – Failure to Position ExxonMobil for Long - Term Value 20

ExxonMobil’s static view of the future represents poor risk management and risks continued value destruction • Long - term business planning centered narrowly on projections of oil and gas demand growth for decades • Focus on near - term emissions intensity reduction, despite existential business model risk created by long - term trajectory of growing total emissions • Diversification efforts have delivered more advertising than results • Near total reliance on hope of carbon capture to preserve business model • Scope 3 emissions are an issue for society to resolve, rather than a business risk • Capturing long - term business diversification opportunities and managing business risk requires more dynamic long - term planning • ExxonMobil’s long - term trajectory of growing emissions creates existential long - term business model risk in a rapidly decarbonizing world • Carbon capture – particularly as practiced by ExxonMobil - is unlikely to avoid need for long - term evolution • Scope 3 emissions are a fundamental long - term threat to business model 21

Despite rhetoric, ExxonMobil has shown little interest in even gradually repositioning its business • ExxonMobil significantly lags public integrated oil companies in measures of transition - readiness, scoring better than only state - controlled entities • While recently shifting its rhetoric on the importance of low - carbon strategies, ExxonMobil has paid little actual attention to such efforts Bloomberg Business Model Transition Scores (March 2021) Charts Source: Bloomberg’s report BNEF Oil and Gas Transition Scores, Leaders and Laggards (March 24, 2021).

Not just a climate issue – a valuation issue for all long - term investors • The market ascribes a higher growth multiple to companies positioned to capture value in a decarbonizing world, and a declining terminal value and increased cost of capital to ExxonMobil and peers who are poorly positioned for the future • Major decisions at the Company – from capital allocation to diversification to compensation – are still driven by a long - term view the market is increasingly rejecting • While the cyclical nature of demand continues to create short - term investment opportunities, the longer - term risk is clear Quote Source: James Mackintosh (March 9, 2021).

Coal shows how quickly changes in demand can occur once alternative technologies provide a better product • While ExxonMobil notes that it took 100 years for coal to be phased out, the actual drop in demand occurred relatively rapidly. In fact, 10 years ago forecasts for coal production were nearly twice as high as today • Coal primarily competed with natural gas for power generation, and advances in fracking technology drove more recent competition, while global efforts to decarbonize are more recent factors accelerating the trend away from coal EIA Annual Energy Outlook Coal Production Forecast (Reference Case) 10 12 14 16 18 20 22 24 26 2010 2011 2012 2013 2014 2015 2016 2017 2018 2019 2020 2021 2022 2023 2024 2025 2026 2027 2028 2029 2030 2031 2032 2033 2034 2035 Coal Production Forecast (quadrillion Btu) 2010 Forecast 2012 Forecast 2014 Forecast 2016 Forecast 2018 Forecast 2020 Forecast 26 Source: U.S. Energy Information Administration Annual Energy Outlook in each respective year. 2010 Forecast as of 2010 report , 2012 Forecast as of 2012 report, and so forth.

With the right strategic oversight, ExxonMobil can still play a profitable role in the energy transition • The energy transition will require technological innovation at scale, and the Oil Majors can utilize their size, global influence, and complex energy project expertise to play an important role • The Oil Majors can also create significant long - term value by demonstrating that they have a role to play in the event of a material energy transition • While the idea of ExxonMobil advancing an energy transition may seem farfetched, it is more in line with market sentiment than a decades - long pursuit of continued fossil fuel reserve growth “[T]here is further valuation upside if the Majors can demonstrate a credible transition strategy as it means the terminal value of these businesses are not zero.” Redburn research, May 8, 2020 “Big Oils have shown tremendous ability to adapt to technological change in their 100+ years of history.

Issue #2 – Rhetoric Does Not Address Long - Term Business Risk from Emissions 29

ExxonMobil has sought to obscure long - term risk by distorting its long - term emissions trajectory • While in the past ExxonMobil sought to disrupt the work of Intergovernmental Panel on Climate Change (IPCC), today it seeks to distort the meaning of its work • Arguing that reducing emissions intensity (emissions per unit produced), while ExxonMobil continues to pursue production growth and thus increases overall emissions, puts it on a “Paris consistent” path fails the basic test of logic Source for first bullet: “Exxon states that it has ‘participated in the [IPCC] since its inception in 1988.’ … A primary goa l w as to undermine the IPCC process, sending large delegations to IPCC meetings, targeting IPCC scientists with accusations of ‘scientific cleansing,’ and cherry - pic king data to suggest warming might simply be ’part of a natural warming trend which began nearly 400 years ago.’” (Kate Aronoff (January 8, 2021).

Even by its own limited standards, ExxonMobil has gone backwards and aims to do worse in 2025 than 2010 • Upstream emission intensity has worsened over the last decade, increasing 26% in 2019 vs. 2009 • ExxonMobil has set a target of reducing upstream intensity by 15 - 20% by 2025 (vs. 2016 baseline) for operated assets, which is 6 - 8% higher than 2009 - 2010 • ExxonMobil’s refusal to join the Oil and Gas Methane Partnership (OGMP) 2.0, which requires verified emissions reduction reporting versus using theoretical engineering calculations, calls the legitimacy of its goals into further question Source: ExxonMobil Energy and Carbon Summary 2020 and 2021. 2025 target intensity assumes a 17.5% intensity reduction (mid po int of 15 - 20% target) from 2016; assumes reduction is for all assets vs. company operated assets. 2020 - 24 estimates assume a linear decline in intensi ty.

Minimal investment in more advanced carbon capture mostly produces advertising • ExxonMobil has heavily advertised its investment in a company called Global Thermostat which is pursuing direct air capture, yet this effort is miniscule ($15 million according to Global Thermostat) and appears primarily driven by marketing considerations “ [Global Thermostat] has featured prominently in ExxonMobil’s commercials on YouTube, Twitter, and Facebook. But Global Thermostat’s achievements haven’t matched its promise … [A] ccounts suggest the company has been stymied by setbacks and mismanagement since almost the very beginning and has made little progress in deployment over the past decade . They say its biggest accomplishments, including the deals with blue - chip companies, amounted to less than advertised and in some cases have yet to produce anything … Current and former staffers say it’s unclear exactly what Exxon is doing with Global Thermostat besides advertising it heavily. ” Bloomberg, April 9, 2021 32 Source: Leslie Kaufman & Akshat Rathi (Apr. 9, 2021). A Carbon - Sucking Startup Has Been Paralyzed by Its CEO . Bloomberg.

Latest advertising blitz regarding a theoretical and unfunded carbon capture project lacks any real substance • ExxonMobil recently released ads touting a $100 billion carbon vaporware capture project • This appears to be another attempt to shift focus from long - term risk facing ExxonMobil – There are no specifics and no discussion of where this funding would come from – ExxonMobil’s expertise is primarily in gas separation not deep decarbonization – The entire concept is reliant on the concept of a carbon tax, which has little chance of passage currently in the US, and would decimate oil and gas demand if it did • Even if this were an actual project versus a press release, the IPCC and IEA have made clear such projects must be in addition to dramatic reductions in emissions 33 Source: Elliott Negin (July 31, 2018). ExxonMobil’s Support for a Carbon Tax is a Sham . Union of Concerned Scientists. Oliver Milman (June 20, 2017). Exxon, Shell and BP back carbon tax proposal to curb emissions. The Guardian. “ [ExxonMobil] has consistently paid lip service to a carbon tax since 2009 … But more telling is the fact that the oil giant has never publicly supported a carbon tax bill and consistently funds members of Congress who oppose a carbon tax. How does that square with the company’s avowed position? It doesn’t.” Union of Concerned Scientists, July 31, 2018 “ As further tradeoff for the new tax, the plan would dismantle all major climate regulations, including the Environmental Protection Agency’s authority over CO2 emissions and an ‘outright repeal’ of the clean power plan.” The Guardian, June 20, 2017

Despite claimed support, ExxonMobil’s long - term strategy leaves it entirely unprepared for an actual carbon tax • A meaningful cost on carbon would likely make natural gas - based power more expensive than battery - backed solar and wind as early as 2024, and would dramatically limit natural gas demand growth, ~40% of which is used for power, which ExxonMobil assumes to be a growth driver • Meaningful carbon capture would have a similar impact, as the only way to pay for it would be a charge on carbon or trillions of dollars in government incentives Chart Source: IEA World Energy Outlook 2020 . “Storage adder” are 4 - Hour Battery Storage costs at 25% of nameplate solar capacity, as per NextEra’s ‘Edison Electric Institute Conference’ presentation, Nov. 2020.

A decade of advertising about algae biofuels despite lack of viability shows a similar focus on advertising over reality • ExxonMobil has touted algae biofuels for more than a decade, yet has little to demonstrate for it other than advertising (during this same time period, one of our nominees helped build the world’s largest renewable diesel and jet fuel business) • Its most recent goal of producing 10,000 barrels by 2025 is ~0.02% of ExxonMobil’s refining capacity Sources: Haley Zaremba (January 28, 2020).

Focusing on societal choices while trying to limit those choices is poor long - term risk management • ExxonMobil argues that meaningful decreases in Scope 3 emissions will require “changes in society’s energy choices coupled with the development and deployment of affordable lower - emission technologies” • This is true, but ignores its role in influencing such choices • More importantly, this argument fails to acknowledge that such choices are changing, and that trying to restrict or confuse such choices – versus adapting to them – likely only makes eventual business disruption more severe ExxonMobil quote source: ExxonMobil Press Release, Dec. 14, 2020.

Despite these dynamics, ExxonMobil has repeatedly committed to more aggressive spending than the industry • ExxonMobil by its own admission has in recent years pursued one of the most “aggressive” capex spending plans in the industry, including pursuing heavy growth (versus maintenance) capex, as peers focused on value over volumes • March 2018 – ExxonMobil announces plan to significantly increase capex to $30 billion through 2025 • March 2019 – Company raises capex guidance to $35 billion in 2019 and targets a 25% increase in production from 3.95 million barrels per day (mb/d) to over 5.0 mb/d • March 2020 – ExxonMobil reaffirms spending plans, planning to spend up to $210 billion through 2025 (over 100% of then - current market cap) Long - Term Production Estimates Prior to November 2020 Spending Deferrals Charts Source: Wood Mackenzie Corporate Benchmarking Tool. “Aggressive” quote: Barron’s Dec 1, 2020 interview with Neil Chapm an, Senior Vice President and Management Committee Member.

XOM on the other hand continues to pursue a countercyclical growth strategy.” Morgan Stanley, June 25, 2020 “[ExxonMobil] has taken a different stance to peers on capital spending, choosing to accelerate capex in recent years instead of pulling back. This is clearly not in favour with investors … This has resulted in [ExxonMobil] materially underperforming peers.” RBC Capital Markets, March 6, 2020 “The sector’s track record for overinvesting and destroying value, combined with concerns over the future trajectory for oil demand, has meant that in recent years the market has rewarded those companies that demonstrate capital discipline rather than the pursuit of growth.” Redburn, May 13, 2020 43

Board went to great lengths to avoid adding successful and transformative energy experience • Rather than even meeting with our nominees (the “Nominees”), ExxonMobil added three new directors in a process rife with serious issues Quote sources: Scott Deveau and Ed Hammond (February 4, 2021).

ExxonMobil’s attacks on our nominees cannot withstand scrutiny ExxonMobil Claim Our Response “Two of the candidates don’t have CEO experience at any company …” • The Board has long used having held the CEO role in an unrelated industry as primary criteria, despite a decade of underperformance • Following our campaign, ExxonMobil itself added three new board members with no public company CEO experience • Two of our nominees do have prior CEO experience and ExxonMobil still refused to even meet them, undermining the credibility of this excuse “None of Engine No. 1’s candidates have experience at companies even close to the complexity or scale of ExxonMobil.” • Successful track records and transferability of skill sets matter as much as experience with large companies in completely unrelated industries • None of our nominees are expected to recreate their prior executive roles, just as no one on the Board is expected to develop new drugs • Generating outsized returns in energy and demonstrating industry foresight are highly transferable skills and highly valuable for a Board that has demonstrated neither ability for over a decade, including missing industry trends such as the shale revolution, the shift to focusing on project returns over chasing production growth, and the need to gradually prepare for rather than ignore the energy transition • Even on its face this argument falls flat given current Board composition: Anthem (~$19B market cap at end of tenure of CEO now on Board), State Street (~$24B), Xerox (~$7B) vs. Andeavor (acquired for $23B), Neste (~$26B in 2019, now ~$40B), Vestas (~$18B in 2019, now ~$46B) Quote Sources: ExxonMobil letter to shareholders, filed March 31, 2001. 55

ExxonMobil’s attacks on our nominees cannot withstand scrutiny (cont.) ExxonMobil Claim Our Response “Engine No. 1 wants the company to invest in wind and solar …” • Our nominees have experience across energy, including oil and gas as well as carbon capture and biofuels, both described as vital by Exxon • Understanding the total energy landscape, including opportunities and competitive dynamics, will be vital no matter what opportunities it pursues • While ExxonMobil mischaracterizes our position, its CEO recently told CNBC that at some point it will enter wind and solar. While this may not occur soon, given the Company’s history of missing industry trends, the Board would clearly benefit from greater industry foresight in monitoring such opportunities “[P]lanned investments in new projects will generate 40% of … operating cash flow in 2025. Engine No. 1 has not said where cash flows to pay the dividend will come from if we elect their directors …” • ExxonMobil again mischaracterizes our position, suggesting that we have called for the cessation of all new spending, rather than more disciplined spending like peers • In our first letter to the Company, we noted that a more disciplined capital allocation strategy would strengthen the reliability of the dividend • Rhetoric is particularly notable given that the Board’s history of debt - financed spending on low return projects has created the real threat to its dividend (as evidenced by the fact that ExxonMobil’s dividend yield even prior to COVID had expanded far more than peers due to the market’s concern about its reliability) Source for third bullet: CNBC Squawk Box Interview with ExxonMobil CEO (March 4, 2021) (“The investment opportunities in sol ar and wind, our perspective on that is we need more solutions in addition to those, that’s going to take a little longer time … So I think you’ll see tha t t ransition for ExxonMobil, but it will happen a little later in the cycle as those technologies develop and we start to deploy them at scale.”) Quote Sources: ExxonMobil letter to shareholders, filed March 16, 2001.

Issue #6 – Misaligned Incentives 57

Inverse relationship between management compensation and performance for shareholders • From 2017 - 19, ExxonMobil’s total return was - (12)% and share repurchases were effectively halted in 2017, yet CEO compensation rose 35% during this period • While 2020 CEO compensation was down 33%, ~72% of this reduction was due to the temporary COVID - related decline in the stock price, and the number of shares awarded increased 14% • Stock awards, the largest discretionary compensation component ( ~60%), have grown every year from 2017 - 2020. • In total from 2017 through 2020, CEO pay has totaled over $75 million Source: ExxonMobil proxy statements. 58 ExxonMobil Market Cap. vs. CEO Stock Awards $355 $156 132 150 180 205 120 130 140 150 160 170 180 190 200 210 220 $100 $150 $200 $250 $300 $350 $400 Market Cap CEO Stock awarded Company Market Capitalization ($ Billion) # of shares awarded to CEO (in '000s) Dec 2016 Dec 2017 Dec 2018 Dec 2019 Dec 2020

Disconnect results in part from compensation plans that can reward volumes over sustainable value Source: Company proxy statements. ExxonMobil’s performance metrics are Safety and Operation Integrity, ROCE, Cash Flow from Operations & Asset Sales, and TSR. • Limited disclosure regarding project returns and lack of cost & balance sheet focused metrics limit accountability for cost overruns or overly optimistic price projections on projects described as “advantaged” even as overall returns decline Peers have more objective disclosures that are reported annually, such as Shell’s “Project delivery on schedule/ budget,” Total’s “Pre - dividend organic cash breakeven & Gearing Ratio,” and BP’s “Production costs per barrel, Refining availability, and Cash Cost Reduction” • ExxonMobil’s compensation plan can also reward industry “outperformance” even if the entire industry destroys value, which can encourage capex spending even where shareholders would be better served by increased returns of capital or investments to strengthen the business. ROCE and TSR are compared to industry averages without reference to the overall market or cost of capital BP uses absolute ROACE and Total uses absolute ROE as targets, and Chevron and ConocoPhillips include S&P500 Total Return Index as a peer for TSR 59

Ad hoc changes have also undercut effectiveness of compensation plans Source: Company proxy statements. • Metrics are not assigned specific weights using a pre - set formula, allowing for ad hoc changes including alteration of key compensation metrics • For example, as ExxonMobil created aggressive new growth plans in 2018, the Board removed ‘Free Cash Flow’ and ‘Shareholder Distributions’ as metrics, noting that such metrics could “discourage investment” and replaced them with ‘Cash Flow from Operations’ and ‘Asset Sales’ • Likewise, the Board in 2019 gave “additional emphasis” to the Company’s “progress towards strategic objectives, which included a strong focus on the Company’s growth strategy” • These changes were followed by heavy investment in projects that delivered a low average return, negative FCF, increased doubt regarding ExxonMobil’s dividend sustainability, and negligible share repurchases Peers – Chevron, BP, Shell, Total, ConocoPhillips, Occidental, Pioneer, and EOG – clearly lay out a management scorecard that has well defined weights for metrics and targets 60

Long - Term Strategy – Focus on profitability today while pragmatically repositioning for the future • ExxonMobil has no plan to reposition for the future and relies instead on misleading arguments about its emissions and carbon capture capabilities, yet argues that we must produce a detailed business diversification plan from the outside looking in • This underscores the key problem : Repositioning for the future will be a massive internal effort requiring a wide array of skills, but there is literally no one on the Board with a record of profitable and transformative energy industry success, which is required along with general business expertise • Adding this experience will enable the Board to begin the hard work of ensuring ExxonMobil has a place in the future of energy, which we believe includes: – Fully exploring new growth areas with the benefit of relevant Board expertise – Leveraging this effort, together with improved capital allocation discipline, to set long - term total emissions reduction targets that are truly Paris consistent – Developing a realistic carbon capture approach that acknowledges that gas separation is not “leading” carbon capture technology and that even advanced carbon capture is unlikely to save its business model – Committing to more robust and independently verified methane reduction efforts including GMPO 2.0 68

Capital Allocation – Long - term commitment to a coherent returns - focused strategy • ExxonMobil has cut 2022 - 25 capex guidance in response to financial and investor pressure, but most spending has been deferred rather than canceled • Even within this range there is wide flexibility; next year’s capex at the high end would be over 50% higher than this year’s capex, and nothing in the Board’s history suggests it can be trusted to help guide such near - term or long - term decisions • While ExxonMobil has focused investors in the short - term on its most advantaged projects to enhance projected returns, the Board must develop a consistent strategy for all future spending that strengthens the balance sheet and dividend reliability and enables investment in the future, which we believe would include: – Only funding upstream projects that can deliver a high IRR (including allocations for all corporate costs) at conservative prices determined by probabilistically - weighted demand scenarios – Canceling or rejecting projects that fail this test and returning capital to investors or putting it to work strengthening ExxonMobil for the long - term – Preventing average cash break - even prices after capex and dividend payments from ever again exceeding conservative levels – Maintaining this discipline even during periods of higher oil and gas prices 69

Incentives – Better aligning performance goals to drivers of shareholder value • We believe a Board with a better understanding of the long - term drivers of value in energy can better set compensation strategy, which we believe would include: – Consistent metrics with disclosed preset weightings and targets, with more cost management and balance sheet - focused metrics – Measuring value creation not just by reference to the oil and gas industry but to the overall market • In the same way that ExxonMobil’s changes to incentive plans to reward production led to a focus on growth even as returns declined, we believe the lack of material energy transition metrics could discourage a focus on the future • By contrast, many peer compensation metrics have evolved to incentivize management to create value by looking at the energy transition as an opportunity – Total: Added compensation metric for “development of the low - carbon businesses (Integrated Gas, Renewables & Power perimeter).” This is in addition to objective GHG reduction targets in both its annual and long - term performance award (25% weight) – Shell: Introduced a 20% weight on “Energy transition” in its long - term incentive plan, which also includes metrics such as “Build the foundation of a material Power business” & “Grow new clean(er) energy product offerings” – BP: Added a 40% weight on “Strategic progress” for granting performance shares, which includes “demonstrate a track record, scale and value in low carbon electricity and energy” 70 Source: Company proxy statements.

Gradually repositioning for the future can enhance returns for long - term investors • ExxonMobil is solely reliant on the hope of consistently high oil and gas prices well into the future to generate long - term returns • Better capital management can boost profitability in a wider range of demand scenarios and protect shareholder value, while enabling investment in the future • Gradually and pragmatically repositioning for the future can also help maximize long - term value by slowly bending the curve on other factors, including: Earnings volatility – The risk of a systematic decline in earnings and free cash flow for undiversified companies increases as prices fluctuate dramatically and future demand & price shocks potentially grow more severe Cost of Capital – ExxonMobil’s cost of capital will likely continue to increase given the market’s view of medium to long - term systematic risks to the industry, and debt pricing may increase if its credit rating continues to fall Market Sentiment – Even if ExxonMobil is successful in boosting free cash flow for some period of time, this is unlikely to create long - term value for investors given the low probability that the market ascribes a growth multiple to such cash flows Quote Source: Liam Denning (Dec. 1 2020).

Now is the time to seize this chance to give ExxonMobil’s Board the experience and skills it needs to face the future 73 • The Board of ExxonMobil will be addressing the most important questions facing the energy industry for years to come, including: – How to responsibly allocate capital to preserve current profitability while also planning for the long - term future of energy – Exploring opportunities to gradually and profitably reposition for the future – How to respond to a rapidly evolving global regulatory landscape and increasing efforts to decarbonize the global economy – Whether and when to seriously pursue cutting edge low carbon solutions including true deep decarbonization projects • The Board has failed to demonstrate the foresight needed to position ExxonMobil for long - term value creation even in the traditional oil and gas business – and the energy industry is not going to get any easier • Whatever the future holds, we believe it is time to add what the Board has been missing – directors with diverse yet highly relevant backgrounds who have successfully tackled energy industry challenges and bring decades of experience in conventional and alternative forms of energy to help best position ExxonMobil for greater long - term value creation • We encourage all shareholders to vote the WHITE proxy card to Reenergize ExxonMobil

APPENDIX Analyzing Long - Term Demand Projections 74

ExxonMobil’s world view has resulted in a failure to position itself for success in lower demand scenarios • While new oil and gas capex will be required under even aggressive decarbonization pathways, ExxonMobil relies on forecasts that discount the possibility of a material energy transition, most recently the IEA stated policies (STEPS) scenario that looks only at stated policies, but these are likely to evolve including this year at COP 26 • This worldview has resulted in aggressive spending and no material efforts at even gradual diversification, which leaves little means to protect shareholder value in alternate demand scenarios (between the top and bottom lines below) Chart Source: ExxonMobil demand of 110mb/d of liquids in 2040 as per 2020 10 - K, adjusted for the IEA STEPS demand for biofuels.

Assumptions Regarding Impact of Population Growth • ExxonMobil points to population growth, particularly in the developing world, and the historical page of change in the industry in predicting future growth in fossil fuel demand • This conclusion does not necessarily follow, however, as continued energy demand growth could also accelerate global decarbonization efforts • Historical rates of response to climate change may also be poor predictors, given that efforts may accelerate as impacts grow increasingly clear, and the developing countries ExxonMobil is counting on for demand growth are likely to suffer the worst impacts of climate change • ~2/3 of the world’s emissions come from countries with net zero by 2050 emissions goals, and as soon as later this year at COP 26 countries may significantly increase their commitments, as the US has already indicated it will do “If no significant action is taken between now and 2040 oil demand is expected to be c52% higher than required under a <2 degree compliant pathway.

ExxonMobil’s Position on Power Generation • The world power generation mix may be radically different in 20 years • ExxonMobil’s 2040 projections regarding the contribution from Solar, Wind and Hydropower, however, assume the world will continue along its present path • However, even natural gas, which is generally assumed to face less immediate demand decline than oil, faces long - term risk Wide Range Of Alternate Power Generation Demand Scenarios Underscores Risks To ExxonMobil’s Narrowly - focused Long - term Strategy “Falling prices for wind and solar power, coupled with government and businesses’ new green goals, are accelerating a shift to cleaner energy and leaving natural gas – long seen by energy companies as a bridge between fossil fuels and renewables – in the lurch. The fuel is also under growing scrutiny for methane leaks, leading some potential customers to skip gas and move ahead to lower - carbon alternatives… That is a risk for Shell and rivals such as Exxon Mobil Corp. and Total SE, which also invested in gas, given that gas projects typically cost billions up front and take decades to recoup that investment.” – Wall Street Journal, March 27, 2021 Quote Source: Sarah McFarlane (Mar. 27, 2021).

Impact of Falling Costs for Renewables • Significant and sustained improvements in the cost of renewable energy production have been consistently underestimated by industry participants, and the cost of both Solar PV and wind energy have rapidly become on par with natural gas - powered generation Looking at where the industry is going, versus a snapshot of where it is today, underscores the long - term risk to oil and gas companies Quote Source: Bloomberg’s New Energy Outlook 2020 .

Chart source: Lazard LCOE Analysis version 14.0. “The [Energy] transition is driven by cheap renewable - energy technologies. Today, either wind or PV are the cheapest new sources of electricity in countries making up around 73% of world GDP. And as costs continue to fall, we expect new - build wind and PV to get cheaper than running existing fossil - fuel power plants.

ExxonMobil’s Position on Electric Vehicles • Average battery prices have fallen at an 18% learning rate since 2010. At this rate, an EV would cost the same as an ICE car by 2024, which could lead to peak demand in ICE cars • ExxonMobil’s EV estimates have trailed IEA, OPEC, BP and BNEF estimates, and have been consistently revised upwards Industry shifts regarding EV – including GM’s recent EV announcement – present additional long - term risk to ExxonMobil • ExxonMobil predicts that EV/hybrids will reach 30% of 2040 new passenger car sales, versus BNEF (57% electric/hybrid) and the IEA Sustainable Development Scenario (75% electric). ExxonMobil also estimates a much larger 2040 global car parc of ~1.9 billion, so while the share of internal combustion engines (ICE) falls, forecasted oil decline is limited Source: ExxonMobil’s 2019 Outlook for Energy , Company’s last published EV estimates.

Impact of Increased Efficiency on Demand Predictions • Increased efficiency in manufacturing and industrial processes could dramatically impact future demand • For example, the IEA’s WEO 2020 assumes that petrochemicals will be the largest driver of future oil demand growth, accounting for three - quarters to 2040 • BNEF, however, predicts petrochemical demand growth to be slower due to increased recycling, and development of alternatives to oil & gas derived feedstocks • We estimate that increasing global recycling rates to 50% by 2040 (from ~20% today) could reduce petrochemical led oil demand by ~20%, and total oil demand by ~3% Gains in efficiency – many relying on existing technology – could result in significantly diminished demand. “A sharp pick - up in efficiency improvements is the single most important element that brings the world towards the Sustainable Development Scenario… This includes efforts to promote the efficient design, use and recycling of materials such as steel, aluminum, cement and plastics. This increased ‘material efficiency’ could be enough in itself to halt the growth in emissions from these sectors . ” IEA World Energy Outlook (2019) Text source: IEA’s World Energy Outlook 2019 & 2020 , Bloomberg NEF.
