EXHIBIT 99.1

ExxonMobil Chairman REX W. TILLERSON commented:

“Earnings in the period rose 3 percent from the third quarter of 2013, driven by higher margins and improved operations in the Downstream and Chemical businesses, partially offset by the impact of lower Upstream realizations.

ExxonMobil’s quarterly results demonstrate the strength of our integrated business model. Integration across Upstream, Downstream and Chemical gives us competitive advantages in scale, efficiency, technical and commercial capabilities, regardless of market fluctuations over the business cycle.

The Corporation’s cash flow from operations and asset sales through the first nine months of 2014 fully covered net investments and shareholder distributions.

We continue to meet our operational and project development objectives. Upstream production for 2014 remains on track with previous full‑year estimates of 4 million oil‑equivalent barrels per day as the company adds new production from project startups.”

Third Quarter 2014 vs. Third Quarter 2013

Upstream earnings were $6,416 million in the third quarter of 2014, down $297 million from the third quarter of 2013. Lower realizations decreased earnings by $670 million. Favorable volume mix effects increased earnings by $340 million. All other items increased earnings by $30 million.

On an oil‑equivalent basis, production decreased 4.7 percent from the third quarter of 2013. Excluding the impact of the expiry of the Abu Dhabi onshore concession, production decreased 1 percent.

Liquids production totaled 2,065 kbd (thousands of barrels per day), down 134 kbd from the third quarter of 2013. The Abu Dhabi onshore concession expiry reduced volumes by 148 kbd. Excluding this impact, liquids production was up slightly as project ramp‑up and work programs more than offset field decline, divestment impacts and higher downtime.

Third quarter natural gas production was 10,595 mcfd (millions of cubic feet per day), down 319 mcfd from 2013. Field decline and lower entitlement volumes were partly offset by new production from Papua New Guinea and work programs.

Earnings from U.S. Upstream operations were $1,257 million, $207 million higher than the third quarter of 2013. Non‑U.S. Upstream earnings were $5,159 million, down $504 million from the prior year.

Downstream earnings were $1,024 million, up $432 million from the third quarter of 2013.  Stronger margins, primarily refining, increased earnings by $820 million. Volume and mix effects increased earnings by $100 million. All other items, primarily foreign exchange impacts, decreased earnings by $490 million. Petroleum product sales of 5,999 kbd were 32 kbd lower than last year's third quarter.

Earnings from the U.S. Downstream were $460 million, up $145 million from the third quarter of 2013. Non‑U.S. Downstream earnings of $564 million were $287 million higher than last year. 

Chemical earnings of $1,200 million were $175 million higher than the third quarter of 2013. Margins increased earnings by $210 million, with improved commodities realizations partly offset by weaker specialties. Volume and mix effects increased earnings by $10 million. All other items decreased earnings by $40 million. Third quarter prime product sales of 6,249 kt (thousands of metric tons) were essentially flat with last year's third quarter.

Corporate and financing expenses were $570 million for the third quarter of 2014, up $110 million from the third quarter of 2013.

During the third quarter of 2014, Exxon Mobil Corporation purchased 30 million shares of its common stock for the treasury to reduce the number of shares outstanding at a cost of $3 billion. Share purchases to reduce shares outstanding are currently anticipated to equal $3 billion in the fourth quarter of 2014. 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 Nine Months 2014 vs. First Nine Months 2013

Earnings of $25,950 million increased $1,720 million from 2013. Earnings per share increased 11 percent to $6.04.

Upstream earnings were $22,080 million, up $2,025 million from the first nine months of 2013. Lower prices and volumes were more than offset by favorable mix effects, increasing earnings by a net $470 million. All other items, primarily asset sales, increased earnings by $1.6 billion.

On an oil‑equivalent basis, production was down 5.3 percent compared to the same period in 2013. Excluding the impact of the expiry of the Abu Dhabi onshore concession, production decreased 2 percent.

Liquids production of 2,087 kbd decreased 105 kbd compared to 2013.  The Abu Dhabi onshore concession expiry reduced volumes by 137 kbd. Excluding this impact, liquids production was up 1.5 percent, driven by project ramp‑up and work programs.

Natural gas production of 11,115 mcfd decreased 703 mcfd from 2013, as expected U.S. field decline and lower European demand were partially offset by project ramp‑up and work programs.

Earnings from U.S. Upstream operations were $3,694 million, up $689 million from 2013. Earnings outside the U.S. were $18,386 million, up $1,336 million from the prior year.

Downstream earnings of $2,548 million increased $15 million from 2013. Lower margins, mainly refining, decreased earnings by $280 million.  Volume and mix effects increased earnings by $460 million. All other items, primarily unfavorable foreign exchange and tax impacts, partially offset by lower operating expenses, decreased earnings by $160 million. Petroleum product sales of 5,886 kbd increased 35 kbd from 2013.

U.S. Downstream earnings were $1,619 million, up $17 million from 2013. Non‑U.S. Downstream earnings were $929 million, a decrease of $2 million from the prior year.

Chemical earnings of $3,088 million increased $170 million from 2013. Higher margins increased earnings by $20 million, while volume and mix effects increased earnings by $140 million. All other items increased earnings by $10 million. Prime product sales of 18,516 kt were up 530 kt from 2013, driven by increased Singapore production.

Corporate and financing expenses were $1,766 million in the first nine months of 2014, up $490 million from 2013, primarily due to unfavorable tax impacts.

Gross share purchases for the first nine months of 2014 were $9.9 billion, reducing shares outstanding by 100 million shares.

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 2013 Form 10-K.  We assume no duty to update these statements as of any future date. 

Frequently used terms

This press release includes cash flow from operations and asset sales, which is a non‑GAAP financial measure.  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.  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.  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.

Reference to Earnings

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

The term “project” as used in this release can refer to a variety of different activities and does not necessarily have the same meaning as in any government payment transparency reports.
