Fair Value Measurements

The authoritative guidance for fair value measurements provides a framework for measuring fair value. The

framework establishes a three-level fair value hierarchy based on the nature of the information used to measure fair

value. The terms “Level 1” and “Level 2” are accounting terms that refer to different methods of valuing assets. The

terms do not represent the relative risk or credit quality of an investment. The fair value hierarchies for the Plan

assets are not a measure of the ability of the Plan to meet Plan benefit obligations.

The following tables set forth by level, within the fair value hierarchy, the Plan's assets at fair value:

Note 5: Fair Value Measurements (continued)


			Fair Value Measurements at

(millions of dollars)
Description of investments	Value		Quoted Prices In Active Markets for Identical Assets (Level 1)		Significant Other Observable Inputs (Level 2)

ExxonMobil common stock	7,361		7,361	(1)
U.S. Government Securities	2,936				2,936	(2)
Corporate Debt Securities	100				100	(2)

Total	10,397		7,361		3,036

Common/Collective trusts (at net asset value)**:

Small & Mid Cap Fund	3,293	(3)
World Ex-US Equity Fund	2,390	(3)
Aggregate Bond Fund	1,322	(4)
Short term investments	246	(5)

Total	25,652

(1) For ExxonMobil common stock, fair value is based on observable quoted prices on an active exchange.

(2) For U.S. government securities and corporate debt securities, fair value is based on observable inputs of comparable

market transactions.

(3) Investments in common and preferred stocks held in the form of units in common/collective trusts are redeemable daily at

the unit value, including the measurement date. The fair value of the underlying securities owned by the common/collective trusts

is based on observable quoted prices on an active exchange.

(4) Investments in debt securities and fixed income assets held in the form of units in common/collective trusts are redeemable

daily at the unit value, including the measurement date.

(5) Short term investments held in the form of units in common/collective trusts are redeemable daily at the unit value, including

the measurement date.

* There are no “Level 3” investments.

** Certain investments that are measured at fair value using the net asset value per share (or its equivalent) practical expedient

have not been categorized in the fair value hierarchy. The fair value amounts presented in this table are intended to permit

reconciliation of the fair value hierarchy to the amounts in the Statements of Net Assets.

In accordance with the Savings Plan Securities Lending Agreement with The Northern Trust Company, the market value of the collateral held at the time of trade execution is required to be at least 102 percent of the market value of securities on loan or at least 105 percent if the collateral held and securities on loan are denominated in different currencies. The fair value of U.S. Government securities on loan was $0 and $2 million, at December 31, 2025 and 2024, respectively. The securities on loan are reflected in the Statements of Net Assets Available for Benefits at December 31, 2025 and 2024 and the Schedule of Assets (Held At End Of Year). The value of cash collateral obtained and reinvested in short term investments is reflected as a liability on the Plan’s financial statements. Purchases and sales of securities are recorded on a trade-date basis. "Dividends" only includes dividends on ExxonMobil stock, and any dividends related to the NT CCT equity funds are reflected as part of the "Net appreciation/(depreciation) in fair value of investments". "Interest" includes only interest from fixed income securities held in the Common Assets Portfolio and from short term cash investments. Interest related to the NT Bond Fund CCT is reflected as part of the "Net appreciation/(depreciation) in fair value of investments". Net appreciation / depreciation in the current value of investments includes realized gains and losses on investments sold or disposed of during the year and unrealized gains and losses on investments held at year end. Transfers-in at fair value include participant-initiated rollovers of certain distributions from other tax-qualified plans into the Plan.
Use of Estimates	Use of Estimates The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that affect the reported amounts of assets available for benefits, liabilities and disclosure of contingent liabilities at the date of the financial statements, and the reported amounts of changes in net assets available for benefits during the reporting period. Actual results could differ from those estimates.
Risks and Uncentainties	Risks and Uncertainties The Plan participants invest in various investment options offered by the Plan. Investments in these Plan-offered options are subject to various risks, such as interest rate, market value, and credit risks. Market risks include global events which could impact the value of investments securities, such as pandemics or international conflicts. Due to the level of risk associated with certain investment securities, it is at least reasonably possible that changes in the values of investment securities will occur in the near term and that such changes could materially affect the amounts reported in the Statements of Net Assets Available for Benefits.
Expenses	Expenses Investment income from all sources is stated net of brokerage fees on purchases and sales of ExxonMobil common stock, administrative expenses and investment management fees. Fees for delivery of checks that are expedited upon request by participants and participant loan origination fees are charged to the participant’s account. All other administrative fees are paid by the Company. Administrative expenses are recorded when incurred.

Description of the Plan	Description of the Plan General Active participants in the ExxonMobil Savings Plan ("Plan") are eligible employees of Exxon Mobil Corporation ("ExxonMobil" or the “Company") and certain affiliated employers. The terms and conditions of the Plan are contained in the ExxonMobil Benefit Plans Common Provisions document, the ExxonMobil Savings Plan document, and the ExxonMobil Savings Trust document (collectively, the "Plan Document"). The Plan is an "employee pension benefit plan" described in Section 3(2) of the Employee Retirement Income Security Act of 1974 ("ERISA"), a "defined contribution plan" described in Section 3(34) of ERISA, and a non-leveraged Employee Stock Ownership Plan. The notes to the financial statements give a general description of the Plan. Participants should refer to the Plan Document for a more complete discussion of the Plan's provisions. Contributions The Plan permits participant contributions that range from 6 percent to 20 percent of each participant’s eligible pay. The Company matches only the minimum 6 percent contribution in an amount equal to 7 percent of a participant’s eligible pay. Employees who are at least age 50 during the plan year and who maximize the combination of their regular pretax and Roth contributions may elect to make additional contributions. Vesting Participants are immediately vested in their contributions and all earnings. Company contributions vest at 100 percent upon the earliest of completion of 3 years of vesting service, reaching age 65 while employed, or death while an employee. Forfeitures During 2025, employer contributions totaling $2.6 million were forfeited by terminating employees and used to offset employer contributions. Other Plan Provisions Other Plan provisions including eligibility, enrollment, participation, forfeiture, loans, benefit payments (including withdrawals and distributions), and investment options are described in the Plan Document. Plan Termination The Company may terminate or amend the Plan at any time. In the event of termination, the net assets of the Plan will be distributed in accordance with ERISA.
