EXHIBIT 99.1

ExxonMobil Chairman REX W. TILLERSON commented: 

“ExxonMobil’s first quarter earnings and cash flow reflect the company’s continuing focus on delivering profitable growth and creating long-term shareholder value.  Strong performance in the Upstream benefitted from improved production mix and increased unit profitability.

First quarter 2014 earnings were $9.1 billion, down 4 percent from the first quarter of 2013.  Upstream earnings were $7.8 billion, up 11 percent from the previous year.

Capital and exploration expenditures for the first quarter were $8.4 billion, down 28 percent from the first quarter of 2013.   

The Corporation distributed $5.7 billion to shareholders in the first quarter through dividends and share purchases to reduce shares outstanding.”

First Quarter 2014 vs. First Quarter 2013

Upstream earnings were $7,783 million in the first quarter of 2014, up $746 million from the first quarter of 2013.  Higher natural gas realizations, partially offset by lower liquids realizations, increased earnings by $410 million.  Production volume and mix effects increased earnings by $20 million.  All other items, including asset management impacts, increased earnings by $320 million.

On an oil-equivalent basis, production decreased 5.6 percent from the first quarter of 2013.  Excluding the impact of the expiry of the Abu Dhabi onshore concession, production decreased 2.9 percent. 

Liquids production totaled 2,148 kbd (thousands of barrels per day), down 45 kbd from the first quarter of 2013.  The Abu Dhabi onshore concession expiry reduced volumes by 118 kbd.  Excluding this impact, liquids production was up 3.3 percent, driven by project ramp-up, mainly at Kearl, and lower downtime. 

First quarter natural gas production was 12,016 mcfd (millions of cubic feet per day), down 1,197 mcfd from 2013, primarily due to lower demand.

Earnings from U.S. Upstream operations were $1,244 million, $385 million higher than the first quarter of 2013.  Non-U.S. Upstream earnings were $6,539 million, up $361 million from the prior year.

Downstream earnings were $813 million, down $732 million from the first quarter of 2013.  Weaker margins, mainly in refining, decreased earnings by $740 million.  Volume and mix effects increased earnings by $80 million.  All other items decreased earnings by a net $70 million.  Petroleum product sales of 5,817 kbd were 62 kbd higher than last year's first quarter.

Earnings from the U.S. Downstream were $623 million, down $416 million from the first quarter of 2013.  Non-U.S. Downstream earnings of $190 million were $316 million lower than last year. 

Chemical earnings of $1,047 million were $90 million lower than the first quarter of 2013.  Weaker margins decreased earnings by $90 million, while volume and mix effects increased earnings by $40 million.  All other items decreased earnings by $40 million.  First quarter prime product sales of 6,128 kt (thousands of metric tons) were 218 kt higher than last year's first quarter, driven by increased Singapore production.

Corporate and financing expenses were $543 million for the first quarter of 2014, up $324 million from the first quarter of 2013, due primarily to the absence of favorable tax impacts.

During the first quarter of 2014, Exxon Mobil Corporation purchased nearly 41 million shares of its common stock for the treasury at a gross cost of $3.9 billion.  These purchases included $3 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 $3 billion in the second 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.

Estimates of key financial and operating data follow. 

ExxonMobil will discuss financial and operating results and other matters during a webcast at 10 a.m. Central time on May 1, 2014.  To listen to the event live or in archive, go to our website at exxonmobil.com. 

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.
