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

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.

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

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
