• Cash flow from operating activities of $11.1 billion highest since the third quarter of 2014
• Ninth discovery offshore Guyana, newly acquired acreage in Brazil enhance Upstream opportunities
• Integration advantages further enhanced by midstream connectivity to Permian and Western Canada

Exxon Mobil Corporation (NYSE:XOM):

Exxon Mobil Corporation today announced estimated third quarter 2018 earnings of $6.2 billion, or $1.46 per share assuming dilution, compared with $4 billion a year earlier. Cash flow from operations and asset sales was $12.6 billion, including proceeds associated with asset sales of $1.5 billion. During the quarter, the company distributed $3.5 billion in dividends to shareholders. Capital and exploration expenditures were $6.6 billion, up 10 percent from the prior year.

Oil-equivalent production was 3.8 million barrels per day, down 2 percent from the third quarter of 2017. Excluding entitlement effects and divestments, liquids production increased 6 percent, as growth in North America more than offset decline and higher downtime. Natural gas volumes decreased 4 percent, excluding entitlement effects and divestments, largely due to a continuing near-term shift in U.S. unconventional development from dry gas to liquids.

"We are seeing the benefits of integration as we capture value from advantaged feedstock from the Permian and Western Canada for our North American refineries," said Darren W. Woods, chairman and chief executive officer. "The logistical network we've established provides reliable connectivity between Upstream production and manufacturing facilities. Operational performance improved significantly versus the second quarter with lower levels of scheduled maintenance and reliability levels in line with our expectations."

During the first nine months of 2018, Exxon Mobil Corporation purchased 5 million shares of its common stock for the treasury at a gross cost of $425 million. These shares were acquired to offset dilution in conjunction with the company's benefit plans and programs. The corporation will continue to acquire shares to offset dilution in conjunction with its benefit plans and programs, but does not currently plan on making purchases to reduce shares outstanding.

ExxonMobil will discuss financial and operating results and other matters during a webcast at 8:30 a.m. Central Time on November 2, 2018. To listen to the event or access an archived replay, please visit www.exxonmobil.com.

Outlooks, projections, goals, targets, descriptions of business plans and objectives, and other statements of future events or conditions in this release are forward-looking statements. Actual future results, including project plans, capacities, and timing; resource recoveries; earnings, margins and volume growth and mix; and maintenance activities could differ materially due to a number of factors. These include changes in supply and demand for oil, gas, and petrochemicals or other market conditions affecting the oil, gas, and petrochemical industries; reservoir performance; timely completion of new projects; the impact of fiscal and commercial terms and the outcome of commercial negotiations; changes in law, taxes, or government regulation and timely granting of governmental permits; war and other political or security disturbances; the actions of competitors; the capture of efficiencies between business lines; unforeseen technical or operating difficulties; unexpected technological developments; general economic conditions including the occurrence and duration of economic recessions; the results of research programs; and other factors discussed under the heading Factors Affecting Future Results on the Investors page of our website at www.exxonmobil.com and in Item 1A of ExxonMobil's 2017 Form 10-K. We assume no duty to update these statements as of any future date.

Forward-looking statements in this release regarding future earnings refer to plans outlined at ExxonMobil's Analysts' Meeting held on March 7, 2018. The growth figures presented at that meeting are not forecasts of actual future results but were intended to help quantify future potential and goals of management plans and initiatives. See the complete March 7, 2018 presentation available in archive form (including the Cautionary Statement and Supplemental Information included with that presentation) on the Investors page of our website at www.exxonmobil.com for more detailed information. That material includes a description of the assumptions underlying these potential growth estimates including a flat real oil price of $60 per barrel, downstream and chemical margins consistent with 2017 levels, and future gas prices consistent with our internal company plans, as well as a reconciliation of adjusted 2017 earnings used as a baseline.

This press release 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 for 2018 period on page 7 and for 2018 and 2017 periods in Attachment V.

This press release also includes total taxes including sales-based taxes. This is a broader indicator of the total tax burden on the corporation's products and earnings, including certain sales and value-added taxes imposed on and concurrent with revenue-producing transactions with customers and collected on behalf of governmental authorities ("sales-based taxes"). It combines "Income taxes" and "Total other taxes and duties" with sales-based taxes, which are reported net in the income statement. We believe it is useful for the corporation and its investors to understand the total tax burden imposed on the corporation's products and earnings. A reconciliation to total taxes is shown as part of the Estimated Key Financial and Operating Data in Attachment I.

References to the resource base and other quantities of oil, natural gas or condensate may include amounts that are not yet classified as "proved reserves" under SEC definitions, but which we believe will likely be moved into the "proved reserves" category and produced in the future. 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. Further information on ExxonMobil's frequently used financial and operating measures and other terms including "Cash flow from operations and asset sales", and "Total taxes including sales-based taxes" is contained under the heading "Frequently Used Terms" available through the "Investors" section of our website at exxonmobil.com.

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.
