1Q 2026 Earnings Considerations

To give perspective regarding market and planned factors affecting 1Q 2026 results, we are providing the following summary of items management believes will impact 1Q 2026 results relative to 4Q 2025 results. These factors are generally limited to significant planned activities, market dynamics, and seasonal demand patterns. This quarter also includes additional factors associated with the ongoing situation in the Middle East and related disruptions. This is only intended to provide information regarding current estimates of these factors. It is not comprehensive of all changes between 4Q 2025 and 1Q 2026 results and is not an estimate of 1Q 2026 earnings for the Corporation. For example, the table below does not reflect operating performance; ongoing improvement initiatives; impacts from the seasonality of base operating expenses; unscheduled downtime; or foreign exchange fluctuation, among other factors. Further, this list may not account for all adjustments and charges required to fully reflect the changes in industry conditions and are subject to finalization of the Corporation’s financial reporting process for 1Q 2026.

References and updates to previous guidance, not included in ranges above, from 4Q25 earnings call materials
• $500 million to $700 million of higher earnings from lower seasonal after-tax expenses, excluding DD&A, expected in the first quarter
• ($200) million to ($100) million of lower earnings primarily from non-Middle East lower volumes due to Upstream downtime
• ($1.1) billion to ($900) million of Corporate & Financing expenses
• Absence of Gravenchon refinery throughput
• Anticipated corporate total pre-tax DD&A of approximately $6.5 billion to $6.8 billion

Impacts on ExxonMobil assets as a result of disruptions in the Middle East region
• Upstream assets in Qatar and the UAE, which accounted for approximately 20% of our 2025 global oil-equivalent barrels of production, were impacted by production disruptions beginning in early March
• Unavailability of crude deliveries impacting refinery throughput
Additional details on the company's status in the Middle East and globally are attached in Exhibit 99.2

Accounting for timing effects
Physical shipments of hydrocarbons and finished products are often hedged using financial derivatives in the normal course of business. At the end of each quarter, accounting standards require open financial derivatives to be marked to current period-end prices (typically referred to as “mark to market”) with the corresponding value reflected in current period earnings. The associated physical shipments are not marked to current period-end prices but valued on the balance sheet in inventory based on LIFO accounting rules. As a result, unlike the financial derivatives, the value of the physical shipment is not reflected in earnings until the transaction is complete. This mismatch between the valuation of the financial derivatives and the associated physical transaction results in a timing difference in earnings that unwinds over subsequent quarters consistently delivering a net profit. LIFO valuation also drives timing differences between the accounting recognition of the settlement of the derivatives and their offsetting physical shipments. Together, these are referred to as timing effects.

In periods of rising prices, the timing effects are typically negative, while in periods of decreasing prices, the timing effects are typically positive. Importantly, excluding timing impacts, these trading and optimization activities have consistently delivered positive earnings to the Corporation. Crude and products trading activity, which accounted for the majority of timing impacts in the first quarter, is included in the Energy Products segment. Natural gas related impacts are included in the Upstream segment.
1


1 Change in liquids price includes impacts from the change in crude, condensate, and NGL realizations at prior period sales volumes.
2 Change in gas price includes impacts from the change in natural gas realizations (including LNG) at prior period sales volumes and settled gas trading.
3 Changes in industry margins are estimated market effects on crude and petroleum products, specialty basestocks, and chemicals at prior period volumes which include market impacts on trading in the respective segments.
4 Timing effects are primarily related to unsettled derivatives (mark-to-market) and other earnings impacts driven by timing differences between the settlement of derivatives and their offsetting physical commodity realizations (due to LIFO inventory accounting).
5 Volume disruptions related to Middle East events include impacts from production disruptions, shutdowns, and lower availability of crude deliveries impacting global manufacturing operations.
6 Other Middle East impacts include the loss on a settled financial hedge that was not offset by the associated physical shipment due to supply disruptions in the Middle East.

Outlooks, estimates, projections, and other statements of future financial impacts of certain factors as provided in this publication are forward-looking statements within the meaning of the Private Securities Litigation Reform Act.

All forward-looking statements and the assumptions in this filing speak only as of the date hereof.

Earnings (loss) excluding Identified Items, 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 in a given quarter may be less than $250 million when the item impacts several segments or several periods. 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 (loss) 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.

In accordance with Regulation FD, we are hereby providing notice the Company currently intends to furnish its 1Q 2026 financial results both (1) by posting them on our website at www.exxonmobil.com and (2) in a filing on Form 8-K in the Securities and Exchange Commission EDGAR system, each at approximately 5:30 a.m. CT Friday, May 1, 2026. In the event the EDGAR system experiences technical difficulties, or the Company is unable to successfully complete its 8-K filing at the intended time, investors and the public should look for this information at that time on our website. In case of a failed filing, the Company intends to furnish the information on EDGAR as soon as possible after 5:30 a.m. CT Friday, May 1, 2026.
