EXXON MOBIL CORPORATION ANNOUNCES ESTIMATED

SECOND QUARTER 2009 RESULTS

EXXONMOBIL'S CHAIRMAN REX W. TILLERSON COMMENTED:

"Global economic conditions continue to impact the energy industry both in the volatility of commodity prices and reduced demand for products.  In spite of these challenges, ExxonMobil achieved solid results.  We continued our capital investment program at near record levels while returning over $16 billion to our shareholders during the first half of the year.

ExxonMobil’s second quarter 2009 earnings excluding special items were $4.1 billion, down 66% from the second quarter of 2008.  Earnings per share excluding special items were down 63% reflecting lower earnings and the benefit of the share purchase program.  Earnings for the second quarter of 2009 were $4.0 billion, down 66% from last year, and included a special charge of $140 million for interest related to the Valdez punitive damages award.  Second quarter 2008 earnings included a charge of $290 million related to the Valdez punitive damages award.

First half earnings excluding special items decreased 62% compared to the first half of 2008 reflecting lower crude oil and natural gas realizations.  Earnings for the first half of 2009 were also down 62% versus 2008.

ExxonMobil continued its robust capital investment program.  For the first half of 2009, spending on capital and exploration projects was $12.3 billion, in line with our longer term plan.

The Corporation distributed a total of $7.0 billion to shareholders in the second quarter, through dividends and share purchases to reduce shares outstanding.”

Second Quarter 2009 vs. Second Quarter 2008

Upstream earnings were $3,812 million, down $6,200 million from the second quarter of 2008.  Lower crude oil and natural gas realizations accounted for the decline, reducing earnings approximately $6.1 billion.  

On an oil-equivalent basis, production decreased about 3% from the second quarter of 2008.  Excluding the impacts of entitlement volumes, OPEC quota effects and divestments, production was down about 2.5%.

Liquids production totaled 2,347 kbd (thousands of barrels per day), down 44 kbd from the second quarter of 2008.  Excluding the impacts of entitlement volumes, OPEC quota effects and divestments, liquids production was flat, as field decline was offset by increased production from projects in the United States and west Africa, and lower maintenance activity.

Second quarter natural gas production was 8,013 mcfd (millions of cubic feet per day), down 476 mcfd from 2008.   New production volumes from project additions in Qatar, the United States and the North Sea were more than offset by field decline and lower European demand.

Earnings from U.S. Upstream operations were $813 million, $1,221 million lower than the second quarter of 2008.  Non-U.S. Upstream earnings were $2,999 million, down $4,979 million from last year.

Downstream earnings of $512 million were down $1,046 million from the second quarter of 2008.  Lower margins drove the decline, reducing earnings approximately $1.0 billion, as weaker refining margins more than offset stronger marketing margins.  Petroleum product sales of 6,487 kbd were 288 kbd lower than last year's second quarter, mainly reflecting asset sales and lower demand.

The U.S. Downstream recorded a loss of $15 million, down $308 million from the second quarter of 2008.  Non-U.S. Downstream earnings of $527 million were $738 million lower than last year.

Chemical earnings of $367 million were $320 million lower than the second quarter of 2008.  Lower volumes reduced earnings approximately $150 million, while weaker margins decreased earnings by about $100 million.  Hurricane repair costs and unfavorable foreign exchange effects also reduced earnings.  Second quarter prime product sales of 6,267 kt (thousands of metric tons) were 451 kt lower than the prior year primarily due to weaker demand.

Corporate and financing expenses excluding special items were $601 million, up $314 million due mainly to lower interest income.

During the second quarter of 2009, Exxon Mobil Corporation purchased 75 million shares of its common stock for the treasury at a gross cost of $5.2 billion.  These purchases included $5.0 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 4,880 million at the end of the first quarter to 4,806 million at the end of the second quarter.  Share purchases to reduce shares outstanding are currently anticipated to equal $4.0 billion in the third 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.

First Half 2009 vs. First Half 2008

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 and exploration expenditures; and share purchase levels, could differ materially due to factors including: changes in long-term oil or gas prices or other market or economic 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 were 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.
