ExxonMobil Shareholders: Vote the Blue Proxy Card Today

ExxonMobil shareholders face an important decision at our Annual Meeting of Shareholders on Wednesday, May 26, 2021.

Your board and management team are committed to growing shareholder value, meeting the world’s energy demands and pursuing the right, technology-driven strategy to succeed through the transition to a lower carbon energy future. We have made great progress and are poised for strong value creation.

Now is not the time to deviate from our strategy. Don’t be deceived by a months’ old hedge fund, Engine No. 1, that wants your Company to pursue a vague and undefined plan – which we believe will jeopardize our future and your dividend. Without providing details, they say we should cut investment in our high-return, advantaged projects that will generate earnings and cash flow, while somehow increasing our position in renewable energy markets in which we have no unique competitive advantage. Don’t give them your vote!

VOTE FOR the ExxonMobil

director candidates by voting the BLUE PROXY CARD today.

ExxonMobil’s Industry-Leading Growth Portfolio is

Clearly the Best We’ve Had in 20 Years

Under the oversight of your Board of Directors, ExxonMobil is executing a strategy that prioritizes investment in our high-return, low cost-of-supply assets in Guyana, the Permian and Brazil, and in high-demand specialty Chemical products, to deliver strong cash flows and earnings. This plan will enable us to maintain our dividend, repay debt, and invest in important technologies to help society achieve its climate goals.

We are well positioned for the future. The experts agree:¹

“XOM’s stance is that it has secured the best set of oil & gas development opportunities that it has had in 20 years – the single biggest differentiator versus big oil peers that in our view poorly managed prior oil cycles. We agree. Our rating is buy; XOM is our top major pick.”

“One only has to look at Guyana – increasingly the latest flagship in the portfolio and getting bigger – much bigger – than suggested when ExxonMobil first laid out its objective to double earnings by 2025.”

“…ExxonMobil is the only major oil company to navigate the cycle with both its dividend and capacity to grow the dividend intact.”

- BANK OF AMERICA, MARCH 4, 2021

“…XOM retains an enviable pipeline of highly competitive projects in both the Upstream and Downstream/Chemicals that previously drove the countercyclical invest/grow investment case...”

- UBS GLOBAL RESEARCH, MARCH 8, 2021

“Our positive view on XOM is based on expectations for a positive earnings revision cycle as the macro improves and cost reductions remain top of mind, management’s commitment to capital discipline and prioritization of deleveraging vs. increasing spend in the near term as oil prices improve…”

- GOLDMAN SACHS, APRIL 6, 2021

“Guyana, as with the Permian, is proving to be a transformative asset for the company relative to the rest of the portfolio.”

“Competitive strengths are significant at ExxonMobil as it holds a resilient global portfolio, a focused integrated model, financial strength, and a more focused investment program.”

- EVERCORE ISI, MARCH 4, 2021

“…The dividend is safe and debt should fall, accelerating after 2022 when Guyana production starts to ramp.”

“We believe the coming Permian and Guyana-driven production ramp can help lower [XOM’s cash flow] breakeven and allow for easier funding of the dividend moving forward.”

- WOLFE RESEARCH, MARCH 3, 2021

Sustaining a Strong Dividend and Creating Long-Term Shareholder Value – While Advancing the Transition to a Lower-Carbon Future

We plan to continue to reduce greenhouse gas emissions while developing innovative solutions to help decarbonize the economy, with a focus on the highest emitting sectors: commercial transportation, power generation and heavy industry. These sectors account for 80 percent of energy-related carbon emissions; we are committed to helping them reduce emissions with low carbon solutions.

We are the industry leader in carbon capture and storage (CCS), one of the most important low-carbon technologies required to achieve society’s climate goals at the lowest cost. ExxonMobil has more than 30 years of experience capturing carbon, an equity share in about one-fifth of global CO2 capture capacity and has captured approximately 40 percent of all the captured anthropogenic CO2 in the world.

We also are actively researching and developing other lower emission technologies, such as hydrogen, advanced biofuels and new ways to reduce energy requirements of manufacturing. These projects capitalize on our expertise and drive long-term shareholder value in highly valuable future markets.

ExxonMobil’s Board Has the Right Skills and Experience

– Engine No. 1’s Nominees Do Not!

Since 2016, we have added seven highly qualified independent directors to ensure our board continues to have the expertise it needs, including four recently appointed independent directors in just over a year – Joseph Hooley, Wan Zulkiflee, Michael Angelakis and Jeffrey Ubben. These directors bring valuable expertise in capital allocation across industries, complicated corporate transitions, the energy industry, investor perspectives, Asia-Pacific markets, and environmental, social and governance (ESG) practices.

Engine No. 1’s nominees do not have top leadership experience at companies remotely close to the size, scope and global scale of ExxonMobil. As a result, Engine No. 1 and its director nominees don’t have an appreciation of ExxonMobil’s complexity and breadth – and they lack the experience, expertise and knowledge required to steer a company of its size and importance though the opportunities and challenges of the energy transition. This is clear as they have not been able to articulate how they would provide sustainable growth through the energy transition to support the dividend.

ExxonMobil-operated emissions, reductions, and avoidance performance data are based on a combination of measured and estimated 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, availability of sufficient data, quality of those data, and methodology used for measurement and estimation. Changes to the performance data may be reported as part of our annual publication as new or updated data and/or emission methodologies become available. Emissions, reductions, and avoidance estimates from non-ExxonMobil operated facilities are included in the equity data and similarly may be updated as part of our annual publication. The data includes XTO Energy performance beginning in 2011. ExxonMobil works with industry, including API and IPIECA, to improve emission factors and methodologies.

The term “project” as used in this letter can refer to a variety of different activities and does not necessarily have the same meaning as in any government payment transparency reports.
