EXXON MOBIL CORPORATION ANNOUNCES ESTIMATED

FIRST QUARTER 2009 RESULTS

EXXONMOBIL'S CHAIRMAN REX W. TILLERSON COMMENTED:

"ExxonMobil posted solid first quarter results despite the slowdown in the global marketplace and sharply lower commodity prices.  ExxonMobil’s first quarter earnings were $4.6 billion, down 58% from the first quarter of last year.  Earnings per share were down 54% reflecting lower earnings and the benefit of the share purchase program.

In spite of the dramatic changes to the global economic environment, ExxonMobil is maintaining its long-term focus and disciplined approach to capital investment.  In the first quarter, capital and exploration project spending increased to $5.8 billion, up 5% from last year.  We are committed to investing in our world-class inventory of projects to develop new energy supplies which are vital to economic growth.

The Corporation returned significant cash to shareholders in the first quarter, distributing a total of $9.0 billion through dividends and share purchases to reduce shares outstanding."

First Quarter 2009 vs. First Quarter 2008

Upstream earnings were $3,503 million, down $5,282 million from the first quarter of 2008.  Lower crude oil realizations reduced earnings approximately $4.4 billion while lower natural gas prices decreased earnings about $500 million.  Higher operating expenses reduced earnings about $300 million.

On an oil-equivalent basis, production was up slightly from the first quarter of 2008.  Excluding the impacts of entitlement volumes, OPEC quota effects and divestments, production was up 2%.

Liquids production totaled 2,475 kbd (thousands of barrels per day), up 7 kbd from the first quarter of 2008.  Excluding the impacts of entitlement volumes, OPEC quota effects and divestments, liquids production was up 3%, as increased production from projects in west Africa, the United States and the North Sea, and lower maintenance activity more than offset natural field decline.

First quarter natural gas production was 10,195 mcfd (millions of cubic feet per day), down 34 mcfd from 2008.   New production volumes from project additions in Qatar, the North Sea, and Malaysia were offset by natural field decline and lower European demand.

Earnings from U.S. Upstream operations were $360 million, $1,271 million lower than the first quarter of 2008.  Non-U.S. Upstream earnings were $3,143 million, down $4,011 million from last year.

Downstream earnings of $1,133 million were down $33 million from the first quarter of 2008.  Volume and mix effects reduced earnings about $400 million, while unfavorable foreign exchange impacts and higher operating expenses decreased earnings about $300 million.  Higher margins increased earnings about $700 million.  Petroleum product sales of 6,434 kbd were 387 kbd lower than last year's first quarter, mainly reflecting asset sales and lower demand.

U.S. Downstream earnings were $352 million, down $46 million from the first quarter of 2008.  Non-U.S. Downstream earnings of $781 million were $13 million higher than last year.

Chemical earnings of $350 million were $678 million lower than the first quarter of 2008.  Lower volumes and lower margins each reduced earnings approximately $300 million.  Unfavorable foreign exchange effects also reduced earnings.  First quarter prime product sales of 5,527 kt (thousands of metric tons) were 1,051 kt lower than the prior year due to lower demand.

Corporate and financing expenses of $436 million increased by $347 million due overall to net lower interest income.

During the first quarter of 2009, Exxon Mobil Corporation purchased 107 million shares of its common stock for the treasury at a gross cost of $7.9 billion.  These purchases included $7.0 billion to reduce the number of shares outstanding, with the balance used to offset shares issued in conjunction with the company's benefit plans and programs.  Shares outstanding were reduced from 4,976 million at the end of the fourth quarter to 4,880 million at the end of the first quarter.  Share purchases to reduce shares outstanding are currently anticipated to equal $5.0 billion through the second quarter of 2009.  Purchases may be made in both the open market and through negotiated transactions, and may be increased, decreased or discontinued at any time without prior notice.

Cautionary statement

Statements in this release relating to future plans, projections, events or conditions are forward-looking statements.  Actual results, including project plans, costs, timing, and capacities; capital expenditures; and share purchase levels, could differ materially due to factors including: changes in long-term oil or gas prices or other market conditions affecting the oil and gas industry; completion of repair projects as planned; unforeseen technical difficulties; political events or disturbances; reservoir performance; the outcome of commercial negotiations; wars and acts of terrorism or sabotage; changes in technical or operating conditions; and other factors discussed under the heading "Factors Affecting Future Results" on our website and in Item 1A of ExxonMobil's 2008 Form 10-K.  We assume no duty to update these statements as of any future date.  References to quantities of oil expected to be developed may include amounts not yet classified as proved reserves but that we believe will ultimately be produced.

Frequently used terms

Consistent with previous practice, this press release includes both earnings excluding special items and earnings per share excluding special items.  Both are non-GAAP financial measures and are included to help facilitate comparisons of base business performance across periods.  A reconciliation to net income attributable to ExxonMobil is shown in Attachment II.  The release also includes cash flow from operations and asset sales.  Because of the regular nature of our asset management and divestment program, we believe it is useful for investors to consider sales proceeds 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 is shown in Attachment II.  Further information on ExxonMobil's frequently used financial and operating measures and other terms is contained under the heading "Frequently Used Terms" available through the Investors section of our website at exxonmobil.com.

Accounting standards adopted in first quarter 2009

Effective January 1, 2009, ExxonMobil adopted the Financial Accounting Standards Board's (FASB) Statement No. 160 (FAS 160), “Noncontrolling Interests in Consolidated Financial Statements – an Amendment of ARB No. 51”.  FAS 160 changed the accounting and reporting for minority interests, which will be recharacterized as noncontrolling interests and classified as a component of equity.  FAS 160 required retrospective adoption of the presentation and disclosure requirements for existing minority interests.  All other requirements of FAS 160 will be applied prospectively.  The adoption of FAS 160 did not have a material impact on the Corporation’s financial statements.

References to total corporate earnings mean net income attributable to ExxonMobil (U.S. GAAP) from the income statement.  Unless otherwise indicated, references to earnings, special items, earnings excluding special items, Upstream, Downstream, Chemical and Corporate and Financing segment earnings, and earnings per share are ExxonMobil's share after excluding amounts attributable to noncontrolling interests.

Effective January 1, 2009, ExxonMobil adopted the Financial Accounting Standards Board's Staff Position (FSP) on the Emerging Issues Task Force (EITF) Issue No. 03-6-1, “Determining Whether Instruments Granted in Share-Based Payment Transactions are Participating Securities”.  The FSP required that all unvested share-based payment awards that contain nonforfeitable rights to dividends should be included in the basic Earnings Per Share (EPS) calculation.  Prior-year EPS numbers have been adjusted retrospectively on a consistent basis with 2009 reporting.  This standard did not affect the consolidated financial position or results of operations.
