Exxon Mobil Corporation (NYSE:XOM):

Exxon Mobil Corporation today announced fourth-quarter 2023 earnings of $7.6 billion, or $1.91 per share assuming dilution. Fourth-quarter results included unfavorable identified items of $2.3 billion including a $2.0 billion impairment as a result of regulatory obstacles in California that have prevented production and distribution assets from coming back online. Impairments were partly offset by favorable tax and divestment-related items. Earnings excluding identified items were $10.0 billion, or $2.48 per share assuming dilution. For the full year 2023, the company reported earnings of $36.0 billion, or $8.89 per share assuming dilution.

“Our consistent strategy and execution excellence across the business delivered industry-leading earnings and enabled us to return more cash to shareholders than our peers in 2023 ¹,” said Darren Woods, chairman and chief executive officer.

“These results demonstrate the fundamental improvements we’ve made to our business, reflecting our progress in high-grading our portfolio through investments in advantaged projects and select divestments, while, at the same time, driving a higher level of efficiency and effectiveness throughout the business. The foundation of our success comes from the resiliency, hard work and commitment of our people. As I reflect on our industry-leading results over the past year, I have a great sense of pride in what our people accomplished.”

Financial Highlights

• Fourth-quarter earnings were $7.6 billion versus $9.1 billion in the third quarter. Identified items decreased earnings by $2.3 billion mainly from asset impairments, partly offset by favorable tax and divestment-related items. Earnings excluding identified items were $10.0 billion, an increase of $0.8 billion from the third-quarter. Results strengthened on favorable derivative mark-to-market impacts, improved volume and mix driven by advantaged Guyana and Permian assets, and stronger chemical margins. These factors were partly offset by lower industry refining margins and seasonally higher expenses.

• Delivered full-year 2023 earnings of $36.0 billion and return on capital employed of 15%.

• Achieved $9.7 billion of cumulative structural cost savings in 2023 versus 2019, exceeding the $9 billion plan with an additional $2.3 billion of savings during the year and $0.7 billion during the quarter. The company plans to deliver cumulative savings totaling $15 billion through the end of 2027.

• Generated strong cash flow from operations of $13.7 billion and free cash flow of $8.0 billion in the fourth quarter. For the full year, cash increased $1.9 billion with free cash flow of $36.1 billion. Peer-leading¹ 2023 shareholder distributions of $32.4 billion included $14.9 billion of dividends, and $17.4 billion of share repurchases consistent with announced plans.

• The Corporation declared a first-quarter dividend of $0.95 per share, payable on March 11, 2024, to shareholders of record of Common Stock at the close of business on February 14, 2024. Including the 4% increase in fourth-quarter dividend, the company has increased its annual dividend for a peer-leading¹ 41 consecutive years.

• The debt-to-capital ratio was 16%, and the net-debt-to-capital ratio was 5%, reflecting a period-end cash balance of $31.6 billion.

• The company continued to strengthen its portfolio with the closing of the East Texas upstream assets divestment in the fourth quarter. Total asset sales and divestments generated $4.1 billion of cash proceeds during the year.

• Capital and exploration expenditures were $7.8 billion in the fourth quarter, bringing full-year 2023 expenditures to $26.3 billion, slightly above the top end of the guidance range, as the company opportunistically accelerated activities in the advantaged Permian and Guyana assets, and entered a new lithium business.

ADVANCING CLIMATE SOLUTIONS

Progress Toward Net Zero

• In the Permian Basin, ExxonMobil made great progress on the plan to achieve net zero GHG emissions by 2030. In 2023, the company electrified all of its drilling fleet and replaced over 6,000 natural-gas-driven pneumatic devices in its unconventional operated assets. In addition, ExxonMobil also deployed its first electric fracturing units to further reduce emissions intensity, and signed additional long-term agreements enabling renewable power capacity to support operations. In the quarter, the company also launched a high-altitude monitoring balloon with advanced imaging technology and data processing platforms that has the potential to provide continuous, real-time methane detection. These efforts support ExxonMobil's industry-leading plans to achieve net-zero Scope 1 and 2 emissions from its unconventional operations in the Permian by 2030.

Lithium

• In the fourth quarter, ExxonMobil announced its new Mobil^TM Lithium business with plans to become a leading producer and grow U.S.-based supplies of lithium for the global battery and EV markets. The company's advanced production approach has the potential to produce vast supplies of lithium with fewer environmental impacts than traditional mining operations¹. Work is underway for the first phase of lithium production in southwest Arkansas, an area known to hold significant lithium deposits.

• The company is planning first production for 2027. By 2030, ExxonMobil aims to produce enough Mobil^TM Lithium with the potential to supply approximately one million EVs per year.

Carbon Capture and Storage

• In November, ExxonMobil completed the acquisition of Denbury, Inc. for $4.8 billion of ExxonMobil stock, based on the share price at closing². The company now has the largest owned and operated carbon dioxide (CO2) pipeline network in the United States at 1,300 miles, including nearly 925 miles in Louisiana, Texas and Mississippi, one of the largest U.S. markets for CO2 emissions. The company also has access to more than 15 strategically located onshore CO2 storage sites.

EARNINGS AND VOLUME SUMMARY BY SEGMENT

• Upstream fourth-quarter earnings were $4.1 billion, a decrease of $2.0 billion from the third quarter. Identified items reduced earnings by $2.1 billion this quarter, mainly from the impairment of the idled Santa Ynez Unit assets in California due to regulatory challenges restarting production and distribution. Earnings excluding identified items were $6.3 billion, an increase of $127 million. Higher volumes and improved mix, mainly from Guyana and Permian growth, and stronger gas realizations more than offset lower crude realizations, unfavorable tax impacts, and year-end inventory effects.

• Net production in the fourth quarter was 3.8 million oil-equivalent barrels per day, an increase of 136,000 oil-equivalent barrels per day compared to the prior quarter on favorable entitlement effects and growth in Permian and Guyana. Payara, the third Guyana development, started up in November ahead of schedule with production reaching nameplate capacity of 220,000 barrels per day in mid-January.

• Compared to the same quarter last year, earnings decreased $4.1 billion. Identified items reduced earnings by $2.1 billion this quarter, compared to a reduction of $0.6 billion in the fourth quarter of 2022. Earnings excluding identified items were $6.3 billion, a decrease of $2.5 billion, primarily due to lower natural gas prices. Higher Permian and Guyana volumes and less unfavorable year-end inventory effects provided a partial offset. Net production was flat compared to the same quarter last year. Excluding the impacts from divestments, entitlements, and government-mandated curtailments, net production grew about 70,000 oil-equivalent barrels per day.

• Full-year earnings were $21.3 billion, $15.2 billion less than 2022. Identified items for the year reduced earnings by $2.3 billion, compared to an unfavorable $2.9 billion impact last year. Excluding identified items, earnings decreased $15.8 billion on lower liquids and natural gas realizations, and unfavorable unsettled derivatives mark-to-market effects of $2.4 billion, primarily from the absence of favorable impacts in the prior year. Higher volume contributions from improved portfolio mix added nearly $1 billion, as growth from Guyana and Permian more than offset divestments. Net production in 2023 was 3.7 million oil-equivalent barrels per day, in line with prior year. Production increased 111,000 oil-equivalent barrels per day, excluding impacts from divestments, entitlements, and government-mandated curtailments. Permian and Guyana combined production grew 18% versus 2022.

• In October, ExxonMobil announced an agreement to merge with Pioneer Natural Resources in a $59.5 billion all-stock transaction¹. The combination is expected to generate double-digit returns by recovering more resources, more efficiently, while accelerating emissions reductions². The transaction is expected to close in the second quarter of 2024, pending regulatory and Pioneer shareholder approval.

• Energy Products fourth-quarter earnings totaled $3.2 billion compared to $2.4 billion in the third quarter, an increase of $765 million. A favorable derivatives mark-to-market impact of $1.2 billion and the unwinding of prior quarter unfavorable timing effects more than offset weaker seasonal industry refining margins. Results also improved from favorable tax, year-end inventory impacts, and foreign exchange effects. These factors were partly offset by higher seasonal expenses and lower volumes from higher scheduled maintenance and divestments. Identified items increased earnings by $222 million versus the third quarter. Earnings excluding these items were $3.0 billion for the quarter, an increase of $543 million from the third quarter.

• Compared to the fourth quarter last year, earnings decreased $863 million on weaker industry refining margins and higher project-related expenses, partly offset by favorable derivatives mark-to-market effects. Identified items improved earnings by $873 million mainly from lower additional European taxes on the energy sector and the absence of asset impairments. Earnings excluding these identified items were $3.0 billion, $1.7 billion lower than the fourth quarter last year.

• Full-year 2023 earnings were $12.1 billion, a decrease of $2.8 billion versus 2022 due to the decline in industry refining margins, higher planned maintenance activities and divestments. These factors were partly offset by stronger trading and marketing margins and higher sales volumes from strong reliability and the start-up of the Beaumont refinery expansion. Identified items improved earnings by $828 million mainly from lower additional European taxes on the energy sector and the absence of asset impairments. Earnings excluding identified items were $12.0 billion, a decrease of $3.7 billion from last year.

• Refining throughput for the year was 4.1 million barrels per day, up 38,000 barrels per day from 2022. The record throughput on a current refinery circuit basis was supported by strong reliability and the completion of the 250,000 barrels per day Beaumont refinery expansion in the first quarter of 2023. In addition, with the December completion of the 1.5 million barrels per day strategic Permian crude venture project, both the Beaumont and Baytown refineries have expanded access to advantaged Permian feedstocks.

• Chemical Products fourth-quarter earnings were $189 million compared to $249 million in the third quarter. Identified items mainly associated with asset impairments and other financial reserves reduced earnings by $388 million. Earnings excluding identified items were $577 million for the quarter, an increase of $328 million from the third quarter. Margins improved from lower U.S. feed costs and strong performance product sales. Lower overall seasonal sales were partly offset by new volumes from the recently completed Baytown expansion.

• Current quarter earnings were $61 million lower compared to fourth-quarter 2022. Identified items mainly associated with asset impairments and other financial reserves reduced earnings by $388 million. Earnings excluding identified items were $577 million, $327 million higher on improved margins from lower feed costs.

• Full-year earnings were $1.6 billion, a decrease of $1.9 billion versus 2022. Lower earnings reflect the overall weaker margin environment from bottom-of-cycle market conditions, higher planned maintenance, and unfavorable sales mix effects. Identified items reduced earnings by $388 million. Earnings excluding identified items were $2.0 billion, a decrease of $1.5 billion from 2022.

• Specialty Products continued to deliver strong earnings from high-value products. Fourth-quarter earnings were $650 million, compared to $619 million in the third quarter. Higher margins from improved realizations and lower feed costs, and positive year-end inventory impacts were partly offset by higher seasonal expenses and lower sales volumes. Identified items reduced earnings by $93 million in the quarter.

• Compared to the same quarter last year, earnings decreased by $110 million. Weaker basestock margins were mostly offset by favorable year-end inventory impacts, improved reliability and stronger finished lubes margins.

• Full-year earnings were $2.7 billion, an increase of $299 million compared with 2022 as product differentiation and brand strength drove sustained business performance. Improved finished lubes margins more than offset lower basestock margins and specialty products sales volumes due to weaker global demand.

• Corporate and Financing fourth-quarter net charges of $565 million increased $200 million versus the third quarter driven by unfavorable foreign exchange impacts, partly offset by tax-related identified items.

• Net charges of $565 million in the fourth quarter of 2023 increased $34 million from the same quarter of 2022.

• Full-year net charges of $1.8 billion increased $128 million from 2022 mainly due to the absence of prior year favorable tax-related and other identified items, partly offset by lower financing costs.

This press release also references structural cost savings. Structural cost savings describe decreases in cash opex excluding energy and production taxes as a result of operational efficiencies, workforce reductions, and other cost-saving measures that are expected to be sustainable compared to 2019 levels. Relative to 2019, estimated cumulative structural cost savings totaled $9.7 billion, which included an additional $2.3 billion in 2023. The total change between periods in expenses above will reflect both structural cost savings and other changes in spend, including market factors, such as inflation and foreign exchange impacts, as well as changes in activity levels and costs associated with new operations. Estimates of cumulative annual structural savings may be revised depending on whether cost reductions realized in prior periods are determined to be sustainable compared to 2019 levels. Structural cost savings 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 spending through disciplined expense management.

ExxonMobil will discuss financial and operating results and other matters during a webcast at 7:30 a.m. Central Time on February 2, 2024. To listen to the event or access an archived replay, please visit www.exxonmobil.com.

Actions needed to advance ExxonMobil’s 2030 greenhouse gas emission-reductions plans are incorporated into its medium-term business plans, which are updated annually. The reference case for planning beyond 2030 is based on the Company’s Global Outlook research and publication. The Outlook is reflective of the existing global policy environment and an assumption of increasing policy stringency and technology improvement to 2050. However, the Global Outlook does not attempt to project the degree of required future policy and technology advancement and deployment for the world, or ExxonMobil, to meet net zero by 2050. As future policies and technology advancements emerge, they will be incorporated into the Outlook, and the Company’s business plans will be updated accordingly. References to projects or opportunities may not reflect investment decisions made by the corporation or its affiliates. Individual projects or opportunities may advance based on a number of factors, including availability of supportive policy, permitting, technological advancement for cost-effective abatement, insights from the company planning process, and alignment with our partners and other stakeholders. Capital investment guidance in lower-emission investments is based on our corporate plan; however, actual investment levels will be subject to the availability of the opportunity set, public policy support, and focused on returns.

Forward-looking and other statements regarding environmental and other sustainability efforts and aspirations are not an indication that these statements are material to investors or requiring disclosure in our filing with the SEC. In addition, historical, current, and forward-looking environmental and other sustainability-related statements may be based on standards for measuring progress that are still developing, internal controls and processes that continue to evolve, and assumptions that are subject to change in the future, including future rule-making. The release is provided under consistent SEC disclosure requirements and should not be misinterpreted as applying to any other disclosure standards.

Frequently Used Terms and Non-GAAP Measures

This press release includes cash flow from operations and asset sales (non-GAAP). Because of the regular nature of our asset management and divestment program, the company believes it is useful for investors to consider proceeds associated with the sales of subsidiaries, property, plant and equipment, and sales and returns of investments together with cash provided by operating activities when evaluating cash available for investment in the business and financing activities. A reconciliation to net cash provided by operating activities for the 2022 and 2023 periods is shown on page 8.

This press release also includes cash flow from operations and asset sales excluding working capital (non-GAAP). The company believes it is useful for investors to consider these numbers in comparing the underlying performance of the company's business across periods when there are significant period-to-period differences in the amount of changes in working capital. A reconciliation to net cash provided by operating activities for the 2022 and 2023 periods is shown on page 8.

This press release also includes Earnings/(Loss) Excluding Identified Items (non-GAAP), which are earnings/(loss) excluding individually significant non-operational events with, typically, an absolute corporate total earnings impact of at least $250 million in a given quarter. The earnings/(loss) impact of an identified item for an individual segment may be less than $250 million when the item impacts several periods or several segments. Earnings/(loss) excluding Identified Items does include non-operational earnings events or impacts that are generally below the $250 million threshold utilized for identified items. When the effect of these events is significant in aggregate, it is indicated in analysis of period results as part of quarterly earnings press release and teleconference materials. Management uses these figures to improve comparability of the underlying business across multiple periods by isolating and removing significant non-operational events from business results. The Corporation believes this view provides investors increased transparency into business results and trends and provides investors with a view of the business as seen through the eyes of management. Earnings excluding Identified Items is not meant to be viewed in isolation or as a substitute for net income/(loss) attributable to ExxonMobil as prepared in accordance with U.S. GAAP. A reconciliation to earnings is shown for 2023 and 2022 periods in Attachments II-a and II-b. Corresponding per share amounts are shown on page 1 and in Attachment II-a, including a reconciliation to earnings/(loss) per common share – assuming dilution (U.S. GAAP).

This press release also includes total taxes including sales-based taxes. This is a broader indicator of the total tax burden on the Corporation’s products and earnings, including certain sales and value-added taxes imposed on and concurrent with revenue-producing transactions with customers and collected on behalf of governmental authorities (“sales-based taxes”). It combines “Income taxes” and “Total other taxes and duties” with sales-based taxes, which are reported net in the income statement. The company believes it is useful for the Corporation and its investors to understand the total tax burden imposed on the Corporation’s products and earnings. A reconciliation to total taxes is shown in Attachment I-a.

This press release also references free cash flow (non-GAAP). Free cash flow is the sum of net cash provided by operating activities and net cash flow used in investing activities. This measure is useful when evaluating cash available for financing activities, including shareholder distributions, after investment in the business. Free cash flow is not meant to be viewed in isolation or as a substitute for net cash provided by operating activities. A reconciliation to net cash provided by operating activities for the 2022 and 2023 periods is shown on page 8.

References to resources or resource base may include 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 are not intended to correspond to SEC definitions such as “probable” or “possible” reserves. A reconciliation of production excluding divestments, entitlements, and government mandates to actual production is contained in the Supplement to this release included as Exhibit 99.2 to the Form 8-K filed the same day as this news release.

The term “project” as used in this news release can refer to a variety of different activities and does not necessarily have the same meaning as in any government payment transparency reports. Projects or plans may not reflect investment decisions made by the company. Individual opportunities may advance based on a number of factors, including availability of supportive policy, technology for cost-effective abatement, and alignment with our partners and other stakeholders. The company may refer to these opportunities as projects in external disclosures at various stages throughout their progression.

Government mandates are changes to ExxonMobil’s sustainable production levels as a result of production limits or sanctions imposed by governments.

Compound annual growth rate (CAGR) represents the consistent rate at which an investment or business result would have grown had the investment or business result compounded at the same rate each year.

Debt-to-capital ratio is total debt divided by the sum of total debt and equity. Total debt is the sum of notes and loans payable and long-term debt, as reported in the consolidated balance sheet, along with total equity.

Net-debt-to-capital ratio is net debt divided by the sum of net debt and total equity, where net debt is net of cash and cash equivalents, excluding restricted cash.

This press release also references structural cost savings, for more details see page 9.
