EXXON MOBIL CORPORATION ANNOUNCES ESTIMATED

THIRD QUARTER 2012 RESULTS

EXXONMOBIL'S CHAIRMAN REX W. TILLERSON COMMENTED:

“Third quarter results reflect our ongoing commitment to help deliver the energy needed to underpin economic recovery and growth while maintaining our strong focus on safety and environmental performance.

Third quarter 2012 earnings were $9.6 billion, down 7% from the third quarter of 2011. Earnings for the first nine months of 2012 were $34.9 billion, up 10% compared to the first nine months of 2011.

Capital and exploration expenditures were $9.2 billion in the third quarter and a record $27.4 billion for the first nine months of 2012 as we continue pursuing opportunities to find and produce new supplies of oil and natural gas to meet global demand for energy.  

The Corporation distributed $7.6 billion to shareholders in the third quarter through dividends and share purchases to reduce shares outstanding.”

Third Quarter 2012 vs. Third Quarter 2011

Upstream earnings were $5,973 million in the third quarter of 2012, down $2,421 million from the third quarter of 2011.  Production volume and mix effects reduced earnings by $700 million. Lower liquids and natural gas realizations decreased earnings by $130 million. All other items, including the absence of prior year asset sales ($1.0 billion), unfavorable tax items and foreign exchange impacts, decreased earnings by a total of $1.6 billion.

On an oil-equivalent basis, production decreased 7.5% from the third quarter of 2011. Excluding the impacts of entitlement volumes, OPEC quota effects and divestments, production decreased 2.9%.

Liquids production totaled 2,116 kbd (thousands of barrels per day), down 133 kbd from the third quarter of 2011.  Excluding the impacts of entitlement volumes, OPEC quota effects and divestments, liquids production was down 3.1%, as field decline was partially offset by project ramp-up in Angola and Nigeria.

Third quarter natural gas production was 11,061 mcfd (millions of cubic feet per day), down 1,136 mcfd from 2011.  Excluding the impacts of entitlement volumes and divestments, natural gas production was down 2.7%, due primarily to field decline.

Earnings from U.S. Upstream operations were $633 million, $551 million lower than the third quarter of 2011.  Non-U.S. Upstream earnings were $5,340 million, down $1,870 million from the prior year.

Downstream earnings were $3,190 million, up $1,611 million from the third quarter of 2011.  Downstream margins, mainly refining, increased earnings by $850 million, while volume and mix effects were essentially flat.  All other items, including higher gains on asset sales of $360 million, favorable foreign exchange effects, and lower operating expenses, increased earnings by $780 million.  Petroleum product sales of 6,105 kbd were 453 kbd lower than last year's third quarter due mainly to divestments and the Japan restructuring.

Earnings from the U.S. Downstream were $1,441 million, up $631 million from the third quarter of 2011.  Non-U.S. Downstream earnings of $1,749 million were $980 million higher than last year.

Chemical earnings of $790 million were $213 million lower than the third quarter of 2011.  Lower margins decreased earnings by $150 million.  All other items, mainly unfavorable foreign exchange effects, decreased earnings by $60 million.  Third quarter prime product sales of 5,947 kt (thousands of metric tons) were 285 kt lower than last year's third quarter due mainly to the Japan restructuring.

Corporate and financing expenses were $383 million for the third quarter of 2012, down $263 million from the third quarter of 2011, due mainly to favorable tax items.

During the third quarter of 2012, Exxon Mobil Corporation purchased 58 million shares of its common stock for the treasury at a gross cost of $5.1 billion.  These purchases included $5.0 billion to reduce the number of shares outstanding, with the balance used to acquire shares in conjunction with the company’s benefit plans and programs.  Share purchases to reduce shares outstanding are currently anticipated to equal $5 billion in the fourth quarter of 2012.  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.

Natural gas production of 12,249 mcfd decreased 739 mcfd from 2011.  Excluding the impacts of entitlement volumes and divestments, natural gas production was down 1.3%, as field decline was partially offset by higher demand and lower downtime.

Cautionary statement

Statements 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; resource recoveries; and share purchase levels, could differ materially due to factors including: changes in oil or gas prices or other market or economic conditions affecting the oil and gas industry, including the scope and duration of economic recessions; the outcome of exploration and development efforts; changes in law or government regulation, including tax and environmental requirements; the outcome of commercial negotiations; changes in technical or operating conditions; and other factors discussed under the heading "Factors Affecting Future Results" in the “Investors” section of our website and in Item 1A of ExxonMobil's 2011 Form 10-K.  Completion of pending acquisitions will depend on the terms and timing of government approvals and other conditions to closing contained in the applicable agreements.  We assume no duty to update these statements as of any future date. References to quantities of oil or natural gas may include amounts that we believe will ultimately be produced, but that are not yet classified as “proved reserves” under SEC definitions.

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. 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 proceeds associated with the sales of subsidiaries, property, plant and equipment, and sales and returns of investments 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.
