Southwestern Energy Company
Annual Report 2018

Plain-text annual report

Bill Way President & CEO DEAR FELLOW SHAREHOLDERS 2018 was a pivotal year for Southwestern Energy. We refocused, reengineered and reenergized the Company as a leading Appalachia gas and liquids company with an enviable asset base and 45% less debt than at the start of the year while maintaining a value- and returns-driven strategy. We focus on four key areas to deliver long-term value growth: • We have high quality, large scale assets and a great degree of flexibility from our diverse commodity mix, vertical integration and leading transportation portfolio to maximize value in a volatile market. Our returns-oriented approach allocates capital to the highest value generating projects, with each one required to meet a minimum returns requirements, unhedged. • We apply an intense focus on increasing capital efficiency and expanding margin to deepen our inventory. Our repositioning to invest in liquid-rich Appalachian Basin projects is testament to this fact. • We’re building a greater and greater share of our cash flow from gas liquids, which enhances our total margin and total revenues. Liquids accounted for approximately 28% of our 2018 revenues from Appalachia production. We’ve now become one of the major liquids players in the basin and SWN REPOSITIONED REENGINEERED REENERGIZED REPOSITIONED REENGINEERED REENERGIZED Premier quality, large scale assets Strong and flexible balance sheet Leading execution capability Appalachia focused Lower debt Improved margins, more liquids focused Multiple bench opportunities Right-sized access to premium markets Ample liquidity Increased capital efficiency Converting resource to reserves Returns focused capital allocation Continued rigorous cost management Proven leadership team Company outperformance Core value based culture enjoy the highest condensate yield in the basin due to our super-rich acreage. The ability to flex between commodities adds to our resiliency in what continues to be a volatile commodity environment. • We remain committed to achieving a sustainable 2X debt-to-EBITDA ratio while investing within cash flow as we transition away from our recently monetized Fayetteville assets. We focus on both components of this ratio. We paid down $2.1 billion in debt in 2018. We plan to grow EBITDA in 2019 and 2020 by supplementing Appalachia cash flow with a portion of the cash proceeds from the Fayetteville monetization. We are doing more with less, driving further cost efficiencies and performance improvements to return to cash flow neutrality by the end of 2020. We adjust investment for market conditions, and we protect the core economics of those investments through a robust rolling three-year hedging program. As a result of our resource-to-reserves work, we’ve continued to convert our vast Appalachia resources to proved reserves and grow the breadth and depth of our high-value inventory. We aim to achieve an industry-leading cost structure—if we don’t need it or it doesn’t add value, we move on. We leverage our ability to flex activity with pricing to maximize returns in any cost environment. We have a clear agenda of improving efficiency, including longer laterals, reducing costs and improving well productivity. We believe that improved liquidity, favorable leverage, strong cash flow protected with disciplined hedging, ongoing lowering of costs and increasingly efficient operational execution will enhance returns to our investors. As opportunities or ideas outside of our asset base come to us, we’ll evaluate them with the clarity and rigor and discipline that we are known for in our business, and we’ll make decisions around them only when we conclude that those benefits can be fully delivered. We’re always generating ways to improve the short-term and long-term value creation from our assets and drive shareholder value. We have a multifaceted approach with a strong focus on organic growth. We’re taking actions that are expanding margins and returns in every piece of the business benchmarked against our peers. Finally, innovation underlies so much of what we do. We innovate in operations and technology to reduce costs and improve margins. We innovate financially to ensure prudent investments at the lowest accessible capital cost. Most important, we innovate in safety and the environment to protect our people and where they live. Southwestern Energy Company 2018 Annual Report 1 2018 HIGHLIGHTS We successfully monetized the future cash flow from the Fayetteville Shale—both E&P and gathering—raising $1.865 billion before adjustments. In addition to reducing debt, we returned $200 million to shareholders through a share repurchase program that we completed in the first quarter of 2019. The Fayetteville Shale and the people who worked it hold a special place in our hearts and our history. We are grateful for their contributions that have set the stage for a stronger future at Southwestern Energy. As noted above, in 2018 we strengthened our balance sheet by successfully deleveraging by $2.1 billion and significantly reduced costs, which has improved our financial flexibility. We reported net cash from operating activities of $1.22 billion and net cash flow (a non-GAAP measure) of $1.35 billion, generating $100 million of free cash flow above capital investment. With this enhanced flexibility and completion of the Fayetteville monetization, we expect to realize $150 million in annual savings beginning in 2019. We’ve reinvented SWN into a leaner, nimbler and more resilient organization that is ever focused on improving our operational and financial performance every day, week and year. We continue to be careful stewards of our shareholders’ investments, and we are taking actions every day to increase long-term value. Our teams are constantly finding new ways to capture even greater value from the assets. We continue to extend horizontal lateral lengths in drilled and completed wells, obtaining more production from a single wellbore. We also have reengineered completion designs to reduce costs and improve well performance. Our water infrastructure, Company-operated drilling rigs and direct sand sourcing are also contributing savings. Our overall well costs in 2018 averaged $1,130 per foot, and we expect to reduce the cost per foot to $875 in 2019. We are cultivating new methodologies within the Data Analytics, Machine Learning, and Artificial Intelligence realm and using them to guide our engineering teams to better solutions, more robust engineering and financial models, and overall greater insight into how our reservoirs work and how to maximize the value of our resource recovery. CORPORATE RESPONSIBILITY IS A CORE VALUE “Doing the Right Things” is a part of our Formula. We are determined to operate in a safe, reliable and environmentally sensitive manner that considers our impact on the communities where we live and work. Our employees and contractors strive every day to maintain the trust of their neighbors. Here are a few examples: • Methane emissions from our Appalachian assets dropped to 0.056% in 2018, which is over 96% lower than the industry average of 1.62%. 2 SWN REPOSITIONED REENGINEERED REENERGIZED We have a robust “One Team” safety culture, with our employees and our contractors trained and empowered to stop or modify work and look after one another so that they all get home safely to their families and friends every day. Last year the Company set records in many safety statistics. We will not rest, however, until our incidents fall to zero. In closing, I want to personally thank all of our employees, who live by these commitments and are the foundation for our progress and the key to our future success. On behalf of SWN, our board of directors and all of our employees, we sincerely thank you for your continued investment and support. Sincerely, Bill Way President and Chief Executive Officer • For the third straight year, we were freshwater neutral, removing less water from the local environment than we replaced through recycling or special projects in the same watersheds. • Our new water delivery pipelines are removing approximately 170,000 truckloads in 2019 from roadways in Pennsylvania and West Virginia. We are gratified that governmental and non-governmental organizations are recognizing our environmental performance. In particular: • The Environmental Defense Fund gave the Company a “Leadership Spotlight” in its February 2018 report Disclosure Divide for transparent disclosure and continuous improvement on methane emissions. • Our air emissions reporting in our Corporate Responsibility Report was cited as an example of good Reporting in Practice in Setting the Bar: Implementing the TCFD Recommendations for Oil and Gas Methane Disclosure, an October 2018 report by Ceres, the Environmental Defense Fund and PRI. • We included a Climate Change Scenario Analysis in our 2017-2018 Corporate Responsibility Report. • The West Virginia Department of Environmental Protection awarded us its top honor for reclamation work on well pad sites in 2017-18.

This increase was achieved primarily through extensions, discoveries and other additions, along with increases in both price and performance revisions in the Appalachian Basin. Our proved reserves were comprised of 67% natural gas and 33% liquids compared to 75% natural gas and 25% liquids in 2017, driven by an increase in Southwest Appalachia proved reserves. The Northeast Appalachia Division and Southwest Appalachia Division combined total reserve life index increased to 17 years at year-end 2018. Our reserves achieved a pre-tax PV-10 value of $6.5 billion. Our teams have worked on continuing to build upon our inventory in the basin, carefully identifying properties to acquire. We’ve sharpened our focus on this area, too, seeking to expand into areas where profitable production additions exist. As of December 31, 2018, we had 6,364 Bcfe of proved undeveloped reserves, all of which we expect will be developed within five years. During 2018, we invested $491 million to convert 1,096 Bcfe, or 16%, of our proved undeveloped reserves into proved developed reserves. We also added 832 Bcfe of proved undeveloped reserve additions in the Appalachian Basin. 6 SWN REPOSITIONED REENGINEERED REENERGIZED 2018 HIGHLIGHTS $8 $6 $4 $2 $0 $5.8 $6.5 2.0 Fayetteville 3.5 SW Appalachia Appalachia 1.7 SW NE Appalachia 2.1 3.1 NE Appalachia 2017 2018 Southwestern Energy Company 2018 Annual Report 7 Proved Reserves (Tcfe) 14.8 3.7 Fayetteville 11.9 15 10 5 0 4.1 NE Appalachia 4.4 NE Appalachia 2017 2018 NOTE: may not add due to rounding. 7.0 SW Appalachia 7.6 SW Appalachia Pre-Tax PV10 (in billions) FINANCIAL STRENGTH & DISCIPLINE Much stronger position financially with the same sharp focus on achieving attractive returns Our balance sheet ended the year in a stronger position, which in turn enabled us to further invest where and how we needed to in order to grow our business. Last year we were able to reduce debt by $2.1 billion and to achieve ongoing annual savings of $150 million per year from reduced interest and organizational costs. We also implemented our first-ever stock buyback, returning about $200 million in value to shareholders. We are committed to achieving a sustainable 2x debt-to-EBITDA ratio in the future. We are focused on growing EBITDA in the years ahead, by doing more with less, creating further cost efficiencies and performance improvements in order to return to free cash flow by the end of 2020. We remain focused on demonstrating continued financial discipline and have rescheduled our debt maturities so that we have no significant payments until 2025, thus providing greater financial flexibility. 8 SWN REPOSITIONED REENGINEERED REENERGIZED Net Debt / EBITDA (1) 4.5x 2.8x 1.9x (2) 5x 4x 3x 2x 1x 0 2016 2017 2018 (1) For the Company’s reconciliation of net debt and adjusted EBITDA to Generally Accepted Accounting Principles, see “Non-GAAP Reconciliations” on the inside back cover.

We are in the enviable position of being able to shift activity to take advantage of improvements in market pricing, and our moves paid off as higher liquids prices in 2018 increased our overall weighted average realized prices. In 2018, we had record gross operated exit rate production from our Appalachian Basin assets of 2.75 Bcfe per day, 2.0 Bcfe per day net, a 17% increase compared to December 2017, and we expect these assets to continue to deliver robust value growth in 2019. With their significant growth potential, our Appalachian Basin assets are well on the path to self-funding. 10 SWN REPOSITIONED REENGINEERED REENERGIZED Appalachia EBITDA (in millions) $1,250 $1,000 $750 $500 $250 $0 $1,168 $675 $165 2016 2017 2018 2018 HIGHLIGHTS Increasing Liquids Production (MBbls/d) 75 50 25 0 61.3 58.3 45.4 67.1 70.7 2017 Q1 ’18 Q2 ’18 Q3 ’18 Q4 ’18 NGL Oil Southwestern Energy Company 2018 Annual Report 11  OPERATIONAL EXCELLENCE ADVANCES Operations continue to improve with less expensive and more innovative solutions Much like our progress in 2017, we stepped up and delivered further operational efficiencies in our operating areas in 2018. Some key accomplishments included: In 2018, we continued to make improvements in the performance of our Appalachian Basin assets with a primary focus on enhancing margins. During 2018, we executed on this part of our business strategy by: • • • Lowering our costs through drilling, completions and operational efficiencies and optimizing gathering and transportation costs. Delivering operational excellence with improved well productivity and economics from enhanced completion techniques, initiation of water infrastructure projects, optimization of surface equipment and managing reservoir drawdown. Expanding our proved reserve quantities in the Appalachian Basin through our successful drilling program, improved operational performance and improved commodity prices. • Improved production while remaining within original capital program guidance. • Established record production levels in both NE Appalachia and SW Appalachia. Grew liquids production above the forecasted level, which incrementally added value with improved liquids pricing. Extended lateral lengths in Appalachia Divisions; successfully drilled record laterals in both areas. Improved safety performance in drilling, completions, facilities and production operations. Improved operational execution and efficiencies (cycle-time improvements, cost reductions such as direct sand sourcing). Advanced water projects in SW Appalachia and NE Appalachia to reduce well costs in 2019 and beyond. • • • • • 12 SWN REPOSITIONED REENGINEERED REENERGIZED Southwestern Energy Company 2018 Annual Report 13  ENVIRONMENTAL RESPONSIBILITY SWN has an unyielding commitment to environmental responsibility Our environmental efforts have yielded awards and recognition from state agencies, community leaders and industry organizations. While delivering improved well productivity and economics, we also continue to deliver on our commitments to proactively pursue environmentally responsible practices throughout our operations, and thus assure their sustainability. SWN is a leader in implementing technologies to reduce methane emissions in our operations. We believe in a science-based approach to collect real-world data and adopt process improvements that result in true emission reductions for our operating practices. We proactively implement methane mitigation technologies, including reduced methane emissions completions, pneumatic device replacement, emission minimization during liquids unloading, and our leak detection and repair (LDAR) program. Many of these measures are done well in advance of regulatory requirements. Taking these actions makes good business sense for operational efficiency, as well as reinforcing our dedication to environmental sustainability. In 2018, we continued to exceed our goal to maintain a methane intensity commitment of 0.28% as part of our membership in the ONE (Our Nation’s Energy) Future coalition. Our 2018 year-end rate was 0.056%, well below the coalition goal. We are proud to be in our third year as a freshwater neutral company. Meaning, for every gallon of fresh water we use in our operations, we return at least that much to the environment through conservation projects in the basins in which we operate. In 2018*, we had nine fully functioning conservation projects in our three active basins providing over three billion gallons of freshwater benefits to the environment. These projects, such as impaired stream restoration or treatment of acid mine drainage, provide lasting benefits to the environment and communities which today are hosting our operations. There is no company in our industry that can prosper if it doesn’t have a strong commitment to being a safe and responsible operator. We’ve built this into the fabric of our corporate culture, and we continue to make steady progress toward achieving our safety and environmental goals. *SWN sold the Fayetteville asset in December, 2018. 14 SWN REPOSITIONED REENGINEERED REENERGIZED Southwestern Energy Company 2018 Annual Report 15 Executive Officers From left to right: John C.

BUSINESS Southwestern Energy Company (including its subsidiaries, collectively, “we”, “our”, “us”, “the Company” or “Southwestern”) is an independent energy company engaged in exploration, development and production activities, including the related marketing of natural gas, oil and natural gas liquids (“NGLs”) produced in our operations. Southwestern is a holding company whose assets consist of direct and indirect ownership interests in, and whose business is conducted substantially through, its subsidiaries. Currently we operate exclusively in the United States. Our common stock is listed and traded on the NYSE under the ticker symbol “SWN.” Southwestern, which is currently incorporated in Delaware, has its executive offices located at 10000 Energy Drive, Spring, Texas 77389, and can be reached by phone at 832-796-1000. The Company also maintains offices in Tunkhannock, Pennsylvania and Morgantown, West Virginia. Our Business Strategy We aim to deliver sustainable and assured industry-leading returns through excellence in exploration and production and marketing performance from our extensive resource base and targeted expansion of our activities and assets along the hydrocarbon value chain. Our Company’s formula embodies our corporate philosophy and guides how we operate our business: Our formula, “The Right People doing the Right Things, wisely investing the cash flow from our underlying Assets will create Value+,” also guides our business strategy. We always strive to attract and retain strong talent, to work safely and act ethically with unwavering vigilance for the environment and the communities in which we operate, and to creatively apply technical skills, which we believe will grow long-term value for our shareholders. The arrow in our formula is not a straight line: we acknowledge that factors may adversely affect quarter-by-quarter results, but the path over time points to value creation. In applying these core principles, we concentrate on: • Financial Strength. We are committed to rigorously managing our balance sheet and financial risks. We budget to invest from our net cash flow from operations, supplemented over the next two years by a portion of the proceeds from our recent asset sales. Additionally, we protect our projected cash flows through hedging and continue to maintain a strong balance sheet with ample liquidity. • Increasing Margins. We apply strong technical, operational, commercial and marketing skills to reduce costs, improve the productivity of our wells and pursue commercial arrangements to extract greater value. We believe our demonstrated ability to improve margins, especially by leveraging the scale of our large assets, gives us a competitive advantage as we move into the future. • Exercising Capital Allocation Discipline. We continually assess market conditions in order to adjust our capital allocation decisions to maximize shareholder returns. This allocation process includes consideration of multiple alternatives including but not limited to the development of our natural gas and oil assets, strategic acquisitions, reducing debt and returning capital to our shareholders. • Operational Value Creation. We prepare an economic analysis for our drilling programs and other investments based upon the expected net present value added for each dollar to be invested, which we refer to as Present Value Index, or PVI. We target projects that generate the highest returns in excess of our cost of capital. This disciplined investment approach governs our investment decisions at all times, including the current lower-price commodity market. • Dynamic Management of Assets Throughout Life Cycle. We own large-scale, long-life assets in various phases of development. In early stages, we ramp up development through technical, operational and commercial skills, and as they grow we look for ways to maximize their value through efficient operating practices along with applying our commercial and marketing expertise. • Deepening Our Inventory. We continue to expand the inventory of properties that we can develop profitably by converting our extensive resources into proved reserves, targeting additions whose productivity largely has been demonstrated and improving efficiencies in production. SWN 20 FINAL GLOSSY v6 - 4000dpi Double.pdf 4 3/25/19 5:16 PM • The Hydrocarbon Value Chain. We believe that our vertical integration enhances our margins and provides us competitive advantages. For example, we own and operate drilling rigs and well stimulation equipment and are investing in a water transportation project in West Virginia, a portion of which is already in service and providing approximately $0.5 million in savings per well. These activities provide operational flexibility, help protect our margin, lower our well costs, minimize the risk of unavailability of these resources from third parties and capture additional value. • Technological Innovation. Our people constantly search for the next revolutionary technology and other operational advancements to capture greater value in unconventional hydrocarbon resource development. These developments – whether single, step-changing technologies or a combination of several incremental ones – can reduce finding and development costs and thus increase our margins. • Environmental Solutions and Policy Formation. We are a leader in identifying and implementing innovative solutions to unconventional hydrocarbon development to minimize the environmental and community impacts of our activities. We work extensively with governmental, non-governmental and industry stakeholders to develop responsible and cost-effective programs. We demonstrate that a company can operate responsibly and profitably, putting us in a better position to comply with new regulations as they evolve. In recent years, we have faced a challenging commodity price environment that has impacted our revenues and margins. As a result, we implemented a series of strategic initiatives, which were designed to reposition our portfolio to increase operational and financial flexibility, stabilize the Company financially and improve operational performance. Repositioning of Our Portfolio During 2018, we completed the next phase of strategic steps, designed to reposition our portfolio, which allowed us to sharpen our focus on our assets with the highest return. We believe that, in doing so, we will further strengthen our balance sheet and enhance our financial performance. These initiatives included: • Completing the sale of 100% of the equity in certain of our subsidiaries that conducted our operations in Arkansas, which were primarily focused on the Fayetteville Shale (the “Fayetteville Shale sale”); • Responding to commodity price changes by shifting focus to our liquids-rich portfolio in Southwest Appalachia; and • Utilizing a portion of funds realized from the Fayetteville Shale sale to reduce debt and return capital to shareholders. We intend to use the remaining funds to further develop our Appalachian Basin assets in order to accelerate the path to self-funding and for general corporate purposes. Financial Stability During 2018, we focused on enhancing our financial stability by: • Continuing to invest only in those projects that meet our rigorous economic hurdles at strip pricing, adjusting for basis differentials; • Demonstrating financial discipline by investing within our announced plan of cash flow; • • Identifying and implementing structural, process and organizational changes to further reduce general and administrative costs; and Simplifying our capital structure by consolidating the components of our previous credit arrangements into a single senior secured revolving credit facility while increasing liquidity, extending our maturity profile and reducing interest expense. Operational Improvement We improved the performance of our large asset portfolio with a primary focus on enhancing margins and investment returns. During 2018, we executed on this part of our business strategy by: • Lowering our costs through drilling, completions and operational efficiencies and optimizing gathering and transportation costs; • Focusing on delivering operational excellence with improved well productivity and economics from enhanced completion techniques, initiation of water infrastructure projects, optimization of surface equipment and managing reservoir drawdown; and SWN 21 FINAL GLOSSY v6 - 4000dpi Double.pdf 5 3/25/19 5:16 PM • Expanding our proved reserve quantities in the Appalachian Basin through our successful drilling program, improved operational performance and improved commodity prices. The bulk of our operations, which we refer to as Exploration and Production (“E&P”), are focused on the finding and development of natural gas, oil and NGL reserves. We are also focused on creating and capturing additional value through our marketing business and, until the Fayetteville Shale sale, natural gas gathering, all of which we historically have referred to as Midstream. Exploration and Production Overview Our primary business is the exploration for, and production of, natural gas, oil and NGLs, with our current operations solely within the United States. We are currently focused on the development of unconventional natural gas reservoirs located in Pennsylvania and West Virginia. Our operations in northeast Pennsylvania (herein referred to as “Northeast Appalachia”) are primarily focused on the unconventional natural gas reservoir known as the Marcellus Shale, and our operations in West Virginia and southwest Pennsylvania (herein referred to as “Southwest Appalachia”) are focused on the Marcellus Shale, the Utica and the Upper Devonian unconventional natural gas, oil and NGL reservoirs. Collectively, our properties located in Pennsylvania and West Virginia are herein referred to as the “Appalachian Basin.” • Our E&P segment recorded operating income of $794 million in 2018, compared to $549 million in 2017. Our E&P segment operating income increased $245 million in 2018 from 2017 primarily due to a $439 million increase in revenues, partially offset by a $194 million increase in operating expenses due primarily to increased gathering and processing fees resulting from a shift in our production growth to the Appalachian Basin. • Cash flow from operations from our E&P segment was $1.4 billion in 2018, compared to $985 million in 2017. Our cash flow from operations increased in 2018 as the effects of higher realized prices and increased production volumes more than offset increased operating expenses associated with higher liquids activity. On August 30, 2018, we announced our entry into an agreement to effect the Fayetteville Shale sale. The Fayetteville Shale sale closed on December 3, 2018 resulting in net proceeds of approximately $1,650 million, following adjustments of $215 million primarily related to the net cash flows from the economic effective date to the closing date and certain other working capital adjustments. Oilfield Services Vertical Integration We provide certain oilfield services that are strategic and economically beneficial for our E&P operations when our E&P activity levels and market pricing support these activities. This vertical integration lowers our net well costs, allows us to operate efficiently and helps us to mitigate certain operational and environmental risks. These services have included drilling, hydraulic fracturing and water management and movement. As of December 31, 2018, we had seven drilling rigs and two leased pressure pumping spreads with a total capacity of approximately 72,000 horsepower. These assets provide us greater flexibility to align our operational activities with commodity prices. In 2018, we provided drilling rigs for all of our 106 drilled wells. In addition, we provided hydraulic fracturing services utilizing one pressure pumping spread in Southwest Appalachia.

Excluding the impact of the Fayetteville Shale sale, our reserves increased 7% in 2018, compared to 2017, primarily through extensions, discoveries and other additions, along with increases in both price and performance revisions in the Appalachian Basin. • The increase in our reserves in 2017 compared to 2016 was primarily due to extensions, discoveries and other additions in the Appalachian Basin along with increases in both price and performance revisions across our portfolio. • The increase in our after-tax PV-10 value in 2018 compared to 2017 was primarily due to increases in both price and performance revisions in our Appalachian Basin. Excluding the impact of the Fayetteville Shale sale, the increases in our after-tax PV-10 value in both 2018 and 2017, compared to the respective prior years, was primarily due to higher prices and higher reserve levels, including an increasingly larger percentage of oil and NGL reserves. • We are the designated operator of approximately 99% of our reserves, based on the pre-tax PV-10 value of our proved developed producing reserves, and our reserve life index was approximately 17.0 years at year-end 2018, excluding the production from the Fayetteville Shale. The difference in after-tax PV-10 and pre-tax PV-10 (a non-GAAP measure which is reconciled in the 2018 Proved Reserves by Category and Summary Operating Data table below) is the discounted value of future income taxes on the estimated cash flows. Our year-end 2016 after-tax PV-10 computation did not have future income taxes because our tax basis in the associated natural gas and oil properties exceeded expected pre-tax cash inflows, and thus did not differ from the pre- tax values. We believe that the pre-tax PV-10 value of the estimated cash flows related to our estimated proved reserves is a useful supplemental disclosure to the after-tax PV-10 value. Pre-tax PV-10 is based on prices, costs and discount factors that are comparable from company to company, while the after-tax PV-10 is dependent on the unique tax situation of each individual company. We understand that securities analysts use pre-tax PV-10 as one measure of the value of a company’s current proved reserves and to compare relative values among peer companies without regard to income taxes.

Performance, production and price revisions consist of revisions to reserves associated with wells having proved reserves in existence as of the beginning of the year. Extensions, discoveries and other additions include new reserves locations added in the current year. • As of December 31, 2018, we had 6,364 Bcfe of proved undeveloped reserves, all of which we expect will be developed within five years of the initial disclosure as the starting reference date. During 2018, we invested $491 million in connection with converting 1,096 Bcfe, or 16%, of our proved undeveloped reserves as of December 31, 2017 into proved developed reserves and added 832 Bcfe of proved undeveloped reserve additions in the Appalachian Basin. Proved undeveloped reserves also decreased in 2018 primarily due to the sale of the Fayetteville Shale E&P assets. • As of December 31, 2017, we had 6,855 Bcfe of proved undeveloped reserves. During 2017, we invested $23 million in connection with converting 46 Bcfe, or 60%, of our proved undeveloped reserves as of December 31, 2016 into proved developed reserves and added 6,829 Bcfe of proved undeveloped reserve additions in the Appalachian Basin. The significant increase in our proved undeveloped reserve additions in 2017 was the result of adding new undeveloped locations throughout the year through our successful drilling program, improved operational performance and increased commodity pricing across our portfolio. • As of December 31, 2016, we had 77 Bcfe of proved undeveloped reserves. During 2016, we invested $103 million in connection with converting 220 Bcfe, or 50%, of our proved undeveloped reserves as of December 31, 2015 into proved developed reserves and added 25 Bcfe of proved undeveloped reserve additions in the Fayetteville Shale. As a result of the commodity price environment in 2016, we had downward price revisions of 374 Bcfe which were slightly offset by a 203 Bcfe increase due to performance revisions. Our December 31, 2018 proved reserves included 190 Bcfe of proved undeveloped reserves from 30 locations that have a positive present value on an undiscounted basis in compliance with proved reserve requirements but do not have a positive present value when discounted at 10%. These properties have a negative present value of $24 million when discounted at 10%. We have made a final investment decision and are committed to developing these reserves within five years from the date of initial booking. We expect that the development costs for our proved undeveloped reserves of 6,364 Bcfe as of December 31, 2018 will require us to invest an additional $3.8 billion for those reserves to be brought to production. Our ability to make the necessary investments to generate these cash inflows is subject to factors that may be beyond our control. The current commodity price environment has resulted, and could continue to result, in certain reserves no longer being economic to produce, leading to both lower proved reserves and cash flows. We refer you to the risk factors “Natural gas, oil and NGL prices greatly affect our business, including our revenues, profits, liquidity, growth, ability to repay our debt and the value of our assets” and “Significant capital expenditures are required to replace our reserves and conduct our business” in Item 1A of Part I of this Annual Report and to “Management’s Discussion and Analysis of Financial Condition and Results of Operations – Cautionary Statement about Forward-Looking Statements” in Item 7 of Part II of this Annual Report for a more detailed discussion of these factors and other risks. Our Reserve Replacement The reserve replacement ratio measures the ability of an E&P company to add new reserves to replace the reserves that are being depleted by its current production volumes. The reserve replacement ratio, which we discuss below, is an important analytical measure used by investors and peers in the E&P industry to evaluate performance results and long-term prospects. There are limitations as to the usefulness of this measure, as it does not reflect the type of reserves or the cost of adding the reserves or indicate the potential value of the reserve additions. SWN 26 FINAL GLOSSY v6 - 4000dpi Double.pdf 10 3/25/19 5:17 PM In 2018, we replaced 162% of our production volumes with 1,009 Bcfe of proved reserve additions and net upward revisions of 526 Bcfe, essentially all of which were from the Appalachian Basin. Excluding the production from our Fayetteville Shale assets which were divested on December 3, 2018, we replaced 218% of our production in 2018.

(2) The decrease in our net undeveloped acres in 2017 as compared to 2016 is due to leasehold expirations in areas we did not plan on developing. (3) Our proved undeveloped reserve locations increased significantly in 2017, as compared to 2016, primarily through our successful drilling program in less developed areas and improved realized commodity pricing. (4) Includes 394 proved developed producing and 10 proved developed non-producing wells in which we only have an overriding royalty interest. For 2018 as compared to 2017: • Our average completed well cost increased primarily due to the drilling of longer lateral wells, new infrastructure due to increased activity in delineation areas and more complex hydraulic fracturing designs. Our ability to bring our Northeast Appalachia production to market depends on a number of factors including the construction of and/or the availability of capacity on gathering systems and pipelines that we do not own. We refer you to “Midstream” in Item 1 of Part I of this Annual Report for a discussion of our gathering and transportation arrangements for Northeast Appalachia production.

In 2018, our reserves in Southwest Appalachia increased by 592 Bcfe, which included net additions of 457 Bcfe, net upward price revisions of 106 Bcfe and 272 Bcfe of net upward performance revisions, partially offset by production of 243 Bcfe. As of December 31, 2018, we had approximately 297,445 net acres in Southwest Appalachia and had a total of 436 wells on production that we operated.

For 2018 as compared to 2017: • Our average completed well cost increased primarily due to increased completion intensity and larger facilities associated with our liquid-rich wells. The higher well costs are offset by higher liquid production and revenues. In 2018, our NGL and oil production increased by 38% and 46%, respectively, as compared to prior year.

We refer you to “Midstream” within Item 1 of Part I of this Annual Report for a discussion of our gathering and transportation arrangements for Southwest Appalachia production. Fayetteville Shale On August 30, 2018, we entered into an agreement to effect the Fayetteville Shale sale for $1,865 million, subject to customary adjustments. In early December 2018, we completed the Fayetteville Shale sale, resulting in net proceeds of $1,650 million, following adjustments due primarily to the net cash flows from the economic effective date of July 1, 2018, to the closing date. Production in the Fayetteville Shale totaled 243 Bcf for the year ended December 31, 2018, which represented 26% of our total 2018 net production. In 2018, we invested $33 million in the Fayetteville Shale. Other Excluding 2,518,519 acres in New Brunswick, Canada, which have been subject to a government-imposed drilling moratorium since 2015, we held 153,159 net undeveloped acres for the potential development of new resources as of December 31, 2018. This compares to 369,236 net undeveloped acres held at year-end 2017 and 492,389 net undeveloped acres held at year-end 2016, excluding the New Brunswick acreage. We limited our activities in areas beyond our assets in the Appalachian Basin and the Fayetteville Shale during 2018, 2017 and 2016 as a result of the commodity price environment as we focused our capital allocation on these more economically competitive plays. There can be no assurance that any prospects outside of our development plays will result in viable projects or that we will not abandon our initial investments. New Brunswick, Canada. We currently hold exclusive licenses to search and conduct an exploration program covering 2,518,519 net acres in New Brunswick. In 2015, the provincial government in New Brunswick imposed a moratorium on hydraulic fracturing until it is satisfied with a list of conditions. In response to this moratorium, the Company requested and was granted an extension of its licenses to March 2021. In May 2016, the provincial government announced that the moratorium would continue indefinitely. Unless and until the moratorium is lifted, we will not be able to develop these assets. Given this development, we recognized an impairment of $39 million, net of tax, associated with our investment in New Brunswick in 2016. Acquisitions and Divestitures On August 30, 2018, we entered into an agreement to effect the Fayetteville Shale sale for $1,865 million, subject to customary adjustments. In early December 2018, we completed the Fayetteville Shale sale, receiving $1,650 million in net proceeds after adjustments to the purchase price of $215 million primarily due to the net cash flows from the economic effective date of July 1, 2018 to the closing date. In September 2016, we sold approximately 55,000 net acres in West Virginia for approximately $401 million. As of December 2015, these assets included approximately 11 Bcfe of proved reserves.

We began increasing activity in the second half of 2016 as forward pricing improved. • In 2018, we drilled 106 wells (99 of which were spud in 2018), completed 119 wells, placed 138 wells to sales and had 51 wells in progress at year-end. • Of the 51 wells in progress at year-end, 25 and 26 were located in Northeast Appalachia and Southwest Appalachia, respectively. We refer you to “Management’s Discussion and Analysis of Financial Condition and Results of Operations – Liquidity and Capital Resources – Capital Investing” within Item 7 of Part II of this Annual Report for additional discussion of the factors that could impact our planned capital investments in 2019. Sales, Delivery Commitments and Customers Sales. The following tables present historical information about our production volumes for natural gas, oil and NGLs and our average realized natural gas, oil and NGL sales prices: For the years ended December 31, 2017 2018 2016 Average net daily production (MMcfe/day) Production: Natural gas (Bcf) Oil (MBbls) NGLs (MBbls) Total production (Bcfe) 2,591 2,456 2,391 807 3,407 19,706 946 797 2,327 14,245 897 788 2,192 12,372 875 • The increase in production in 2018 resulted primarily from a 64 Bcf increase in net production from our Northeast Appalachia properties and a 60 Bcfe increase in net production from our Southwest Appalachia properties, partially offset by a decrease of 73 Bcf from our Fayetteville Shale properties which were divested on December 3, 2018. • The increase in production in 2017 resulted primarily from a 45 Bcf increase in net production from our Northeast Appalachia properties and a 35 Bcfe increase in net production from our Southwest Appalachia properties, partially offset by a 59 Bcf decrease in net production from our Fayetteville Shale properties.

Sales of natural gas, oil and NGL production are conducted under contracts that reflect current prices and are subject to seasonal price swings. We are unable to predict changes in the market demand and price for natural gas, including changes that may be induced by the effects of weather on demand for our production. We regularly enter into various derivative and other financial arrangements with respect to a portion of our projected production to support certain desired levels of cash flow and to minimize the impact of price fluctuations. We limit derivative agreements to counterparties with appropriate credit standings, and our policies prohibit speculation. As of December 31, 2018, we had the following commodity price derivatives in place on our targeted future production: Natural gas (Bcf) Oil (MBbls) Ethane (MBbls) Propane (MBbls) 443 675 3,687 1,689 108 732 732 – 37 – – – As of February 26, 2019, we had the following commodity price derivatives in place on our targeted future production: For the years ended December 31, 2020 2021 2019 For the years ended December 31, 2020 2021 2019 Natural gas (Bcf) Oil (MBbls) Ethane (MBbls) Propane (MBbls) 376 566 3,091 1,935 126 732 732 366 37 – – – We intend to financially protect pricing on a large portion of expected future production volumes designed to assure certain desired levels of cash flow. We refer you to Item 7A of Part II of this Annual Report, “Quantitative and Qualitative Disclosures about Market Risk,” for further information regarding our derivatives and risk management as of December 31, 2018. SWN 32 FINAL GLOSSY v6 - 4000dpi Double.pdf 16 3/25/19 5:17 PM During 2018, the average price we received for our natural gas production, excluding the impact of derivatives, was approximately $0.64 per Mcf lower than average New York Mercantile Exchange, or NYMEX, prices. Differences between NYMEX and price realized (basis differentials) are due primarily to locational differences and transportation cost. As of December 31, 2018, we have entered into physical sales arrangements to protect the basis on approximately 110 Bcf and 45 Bcf of our 2019 and 2020 expected natural gas production, respectively, at a basis differential to NYMEX natural gas price of approximately ($0.16) per MMBtu and ($0.23) per MMBtu for 2019 and 2020, respectively. We have also entered into basis swaps for approximately 107 Bcf and 59 Bcf of our 2019 and 2020 expected natural gas production, respectively, at a basis differential to NYMEX natural gas price of approximately ($0.29) per MMBtu and ($0.44) per MMBtu for 2019 and 2020, respectively, as of December 31, 2018. We refer you to Note 5 to the consolidated financial statements included in this Annual Report for additional discussion about our derivatives and risk management activities. Delivery Commitments. As of December 31, 2018, we had natural gas delivery commitments of 269 Bcf in 2019 and 89 Bcf in 2020 under existing agreements. These amounts are well below our expected 2019 natural gas production from Northeast Appalachia and Southwest Appalachia and expected 2020 production from our available reserves, which are not subject to any priorities or curtailments that may affect quantities delivered to our customers or any priority allocations or price limitations imposed by federal or state regulatory agencies, or any other factors beyond our control that may affect our ability to meet our contractual obligations other than those discussed in Item 1A “Risk Factors” of Part I of this Annual Report. We expect to be able to fulfill all of our short-term and long-term contractual obligations to provide natural gas from our own production of available reserves; however, if we are unable to do so, we may have to purchase natural gas at market to fulfill our obligations. Customers. Our E&P production is marketed primarily by our Midstream segment. Our customers include major energy companies, utilities and industrial purchasers of natural gas. For the years ended December 31, 2018 and 2017, two subsidiaries of Royal Dutch Shell Plc in aggregate accounted for approximately 10.4% and 10.3%, respectively, of total natural gas, oil and NGL sales. During the year ended December 31, 2016, no single third-party purchaser accounted for 10% or more of our consolidated revenues. We believe that the loss of any one customer would not have an adverse effect on our ability to sell our natural gas, oil and NGL production. Competition All phases of the natural gas and oil industry are highly competitive. We compete in the acquisition and disposition of properties, the search for and development of reserves, the production and marketing of natural gas, oil and NGLs, and the securing of labor, services and equipment required to conduct our operations. Our competitors include major oil and natural gas companies, other independent oil and natural gas companies and individual producers. Many of these competitors have financial and other resources that substantially exceed those available to us. Consequently, we will encounter competition that may affect both the price we receive and contract terms we must offer. We also face competition in accessing pipeline and other services to transport our product to market. Likewise, there are substitutes for the commodities we produce, such as other fuels for power generation, heating and transportation, and those markets in effect compete with us. We cannot predict whether and to what extent any regulatory changes initiated by the Federal Energy Regulatory Commission, or the FERC, or any other new energy legislation or regulations will achieve the goal of increasing competition, lessening preferential treatment and enhancing transparency in markets in which our natural gas production is sold. Similarly, we cannot predict whether legal constraints that have hindered the development of new transportation infrastructure, particularly in the northeastern United States, will continue. However, we do not believe that we will be disproportionately affected as compared to other natural gas and oil producers and marketers by any action taken by the FERC or any other legislative or regulatory body or the status of the development of transportation facilities. Regulation Producing natural gas, oil and NGL resources and transporting and selling production historically have been heavily regulated. For example, state governments regulate the location of wells and establish the minimum size for spacing units. Permits typically are required before drilling. State and local government zoning and land use regulations may also limit the locations for drilling and production. Similar regulations can also affect the location, construction and operation of gathering and other pipelines needed to transport production to market. In addition, various suppliers of goods and services may require licensing. SWN 33 FINAL GLOSSY v6 - 4000dpi Double.pdf 17 3/25/19 5:17 PM Currently in the United States, the price at which natural gas, oil or NGLs may be sold is not regulated. Congress has imposed price regulation from time to time, and there can be no assurance that the current, less stringent regulatory approach will continue. In 2015, the federal government repealed a 40-year ban on the export of crude oil. The export of natural gas continues to require federal permits. Broader freedom to export could lead to higher prices. In addition, the Dodd-Frank Wall Street Reform and Consumer Protection Act (the “Dodd-Frank Act”) and the rules that the U.S. Commodity Futures Trading Commission, or the CFTC, the SEC, and certain other regulators have issued thereunder regulate certain swaps, futures and options contracts in the major energy markets, including for natural gas, oil and NGLs. Producing and transporting natural gas, oil and NGLs is also subject to extensive environmental regulation. We refer you to “Other – Environmental Regulation” in Item 1 of Part 1 of this Annual Report and the risk factor “We are subject to complex federal, state and local laws and regulations that could adversely affect the cost, manner or feasibility of conducting our operations or expose us to significant liabilities” in Item 1A of Part I of this Annual Report for a discussion of the impact of environmental regulation on our business. Midstream We engage in marketing and, prior to the Fayetteville Shale sale, natural gas gathering activities which primarily support our E&P operations. We generate revenue through the marketing of natural gas, oil and NGLs and, historically, from gathering fees associated with in-field gathering activities. The Fayetteville Shale sale, which closed on December 3, 2018, included all gathering assets associated with our previous operations in Arkansas, which comprised the vast majority of our gathering business.

Excluding these charges, operating income from our Midstream segment decreased $22 million in 2018 compared to 2017, primarily due to an $83 million decrease in gas gathering revenues and a $1 million decrease in marketing margin, partially offset by a $33 million decrease in operating costs and expenses and a $29 million increase in gain on sale of assets, net. • Operating income decreased $26 million in 2017 compared to 2016, primarily due to a $47 million decrease in gas gathering revenues related to a decrease in Fayetteville Shale gathered volumes, and a $3 million decrease in marketing margin, partially offset by an $18 million decrease in operating costs and expenses, primarily related to decreased compression rental and maintenance activities, and a $6 million gain on sale of certain compressor equipment. • Revenues increased in 2018, compared to 2017, as the effect of an increase in the price received for volumes marketed was only partially offset by a decrease in volumes gathered. • Revenues increased in 2017, compared to 2016, primarily due to an increase in the price received for volumes marketed which was only partially offset by a decrease in volumes gathered. SWN 34 FINAL GLOSSY v6 - 4000dpi Double.pdf 18 3/25/19 5:17 PM • Cash flow from operations generated by our Midstream segment decreased in 2018, compared to 2017, primarily due to an $83 million decrease in gas gathering revenues, partially offset by a $12 million decrease in cash operating costs and expenses, a $64 million decrease related to timing differences of payables and receivables between the respective periods and a $3 million decrease in Other Income (Loss), Net. • The decrease in cash flow from operations in 2017, compared to 2016, was primarily due to a $26 million decrease in operating income, partially offset by a $12 million increase primarily related to timing differences of payables and receivables between the respective periods. Gas Gathering On December 3, 2018, we sold our gathering operations in Arkansas as part of the Fayetteville Shale sale. Our remaining interests in gathering systems are not expected to generate material revenues. Marketing We attempt to capture opportunities related to the marketing and transportation of natural gas, oil and NGLs primarily involving the marketing of our own equity production and that of royalty owners in our wells. Additionally, we manage portfolio and locational, or basis, risk, acquire transportation rights on third-party pipelines and, in limited circumstances, purchase third-party natural gas to fulfill commitments specific to a geographic location. Northeast Appalachia. Our transportation portfolio in Northeast Appalachia is highly-diversified and allows us to access premium city-gate markets as well as to deliver natural gas from the Appalachia area to the southeast United States. The capacity agreements contain multiple extension and reduction options that allow us to right-size our transportation portfolio as needed for our production or to capture future market opportunities. The table below details our firm transportation, firm sales and total takeaway capacity over the next three years as of February 26, 2019: (MMBtu/d) Firm transportation Firm sales Total firm takeaway – Northeast Appalachia For the remaining year ended December 31, 2020 2019 1,305,000 156,000 1,461,000 1,325,000 54,000 1,379,000 2021 1,316,000 35,000 1,351,000 Southwest Appalachia. Our transportation portfolio for all products in Southwest Appalachia allows us to capitalize on strengthening markets and provides a path for production growth. Agreements with ET Rover Pipeline LLC and Columbia Pipeline Group, Inc.’s Mountaineer Xpress and Gulf Xpress pipelines will allow us to access high-demand markets along the Gulf Coast while also capturing materially improving in-basin pricing. In addition to our natural gas transportation, we have ethane take-away capacity that provides direct access to Mont Belvieu pricing. New ethane cracker demand and export capacity is expected to further strengthen ethane pricing. The table below details our natural gas firm transportation, firm sales and total takeaway capacity over the next three years as of February 26, 2019: (MMBtu/d) Firm transportation Firm sales Total firm takeaway – Southwest Appalachia Demand Charges For the remaining year ended December 31, 2020 777,000 8,000 785,000 2019 694,000 8,000 702,000 2021 868,000 45,000 913,000 As of December 31, 2018, our obligations for demand and similar charges under the firm transportation agreements and gathering agreements totaled approximately $8.8 billion, $3.1 billion of which related to access capacity on future pipeline and gathering infrastructure projects that still require the granting of regulatory approvals and additional construction efforts. We also have guarantee obligations of up to $463 million of that amount. As part of the Fayetteville Shale sale, we retained certain contractual commitments related to firm transportation, with the buyer obligated to pay the transportation provider directly for these charges. As of December 31, 2018, approximately $221 million of these contractual commitments remain of which we will reimburse the buyer for certain of these potential obligations up to approximately $102 million through 2020 depending on the buyer’s actual use. We have recorded an $88 million liability which is the present value of the estimated future payments. The buyer will also assume future asset retirement obligations related to the operations sold. SWN 35 FINAL GLOSSY v6 - 4000dpi Double.pdf 19 3/25/19 5:17 PM Subsequent to December 31, 2018, we agreed to purchase firm transportation with pipelines in the Appalachian Basin starting in 2021 and running through 2032 totaling $357 million in total contractual commitments of which the seller has agreed to reimburse us for $133 million. We refer you to Note 9 – “Commitments and Contingencies” to the consolidated financial statements included in this Annual Report for further details on our demand charges and the risk factor “We have entered into long-term gathering and transportation contracts and have made significant investments in oilfield services businesses, including our drilling rigs, pressure pumping equipment and sand mine operations, to lower costs and secure inputs for our operations and transportation for our production. If our exploration and production activities are curtailed or disrupted, we may not recover our investment in these activities, which could adversely impact our results of operations. In addition, our continued expansion of these operations may adversely impact our relationships with third-party providers” in Item 1A of Part I of this Annual Report. Competition Our marketing activities compete with numerous other companies offering the same services, many of which possess larger financial and other resources than we have. Some of these competitors are other producers and affiliates of companies with extensive pipeline systems that are used for transportation from producers to end users. Other factors affecting competition are the cost and availability of alternative fuels, the level of consumer demand and the cost of and proximity to pipelines and other transportation facilities. We believe that our ability to compete effectively within the marketing segment in the future depends upon establishing and maintaining strong relationships with customers. Customers Our marketing customers include major energy companies, utilities and industrial purchasers of natural gas. For the years ended December 31, 2018 and 2017, two subsidiaries of Royal Dutch Shell Plc in aggregate accounted for approximately 10.4% and 10.3%, respectively, of total natural gas, oil and NGL sales. During the year ended December 31, 2016, no single third-party purchaser accounted for 10% or more of our consolidated revenues. We believe that the loss of any one customer would not have an adverse effect on our ability to sell our natural gas, oil and NGL production. Regulation The transportation of natural gas, oil and NGLs is heavily regulated. Interstate pipelines must obtain authorization from the FERC to operate in interstate commerce, and state governments typically must authorize the construction of pipelines for intrastate service. The FERC currently allows interstate pipelines to adopt market-based rates; however, in the past the FERC has regulated pipeline tariffs and could do so again in the future. State tariff regulations vary. Currently, all pipelines we own are intrastate and immaterial to our operations. State and local permitting, zoning and land use regulations can affect the location, construction and operation of gathering and other pipelines needed to transport production to market, and the lack of new pipeline capacity can limit our ability to reach relevant markets for the sale of the commodities we produce. The transportation of natural gas and oil is also subject to extensive environmental regulation. We refer you to “Other – Environmental Regulation” in Item 1 of Part I of this Annual Report and the risk factor “We are subject to complex federal, state and local laws and regulations that could adversely affect the cost, manner or feasibility of conducting our operations or expose us to significant liabilities” in Item 1A of Part I of this Annual Report for a discussion of the impact of environmental regulation on our business. Other Our other operations have historically consisted of limited real estate development activities and a natural gas vehicles (“NGV”) fueling station in Damascus, Arkansas, which was sold in May 2016. We currently have no significant business activity outside of our E&P and Midstream segments. Environmental Regulation General. Our operations are subject to environmental regulation in the jurisdictions in which we operate. These laws and regulations require permits for drilling wells and the maintenance of bonding requirements to drill or operate wells and also regulate the spacing and location of wells, the method of drilling and casing wells, the surface use and restoration of properties upon which wells are drilled, the plugging and abandoning of wells and the prevention and cleanup of pollutants and other matters. We maintain insurance for costs of clean-up operations in limited instances arising out of sudden and SWN 36 FINAL GLOSSY v6 - 4000dpi Double.pdf 20 3/25/19 5:17 PM accidental events, but otherwise we are not fully insured against all such risks. Although future environmental obligations are not expected to have a material impact on the results of our operations or financial condition, there can be no assurance that future developments, such as increasingly stringent environmental laws or enforcement thereof, will not cause us to incur material environmental liabilities or costs. Failure to comply with these laws and regulations may result in the assessment of administrative, civil and criminal fines and penalties and the imposition of injunctive relief. Certain laws and legal principles can make us liable for environmental damage to property we have sold, and although we generally require purchasers to assume that liability, there is no assurance that they will have sufficient funds should a liability arise. Changes in environmental laws and regulations occur frequently, and any changes may result in more stringent and costly waste handling, storage, transport, disposal or cleanup requirements. We do not expect continued compliance with existing requirements to have a material adverse impact on us, but there can be no assurance that this will continue in the future. We refer you to “Other – Environmental Regulation” in Item 1 of Part 1 of this Annual Report and the risk factor “We are subject to complex federal, state and local laws and regulations that could adversely affect the cost, manner or feasibility of conducting our operations or expose us to significant liabilities” in Item 1A of Part I of this Annual Report for a discussion of the impact of environmental regulation on our business. The following is a summary of the more significant existing environmental and worker health and safety laws and regulations to which we are subject. Certain U.S. Statutes. The Comprehensive Environmental Response, Compensation, and Liability Act, as amended, also known as CERCLA or the “Superfund law,” imposes liability, without regard to fault or the legality of the original conduct, on certain classes of persons that are considered to be responsible for the release of a “hazardous substance” into the environment. These persons include the owner or operator of the disposal site or sites where the release occurred and companies that transported or disposed or arranged for the transport or disposal of the hazardous substances found at the site. Persons who are or were responsible for releases of hazardous substances under CERCLA may be subject to joint and several liability for the costs of cleaning up the hazardous substances that have been released into the environment and for damages to natural resources, and it is not uncommon for neighboring landowners and other third parties to file claims for personal injury and property damage allegedly caused by the hazardous substances released into the environment. The Resource Conservation and Recovery Act, as amended, or RCRA, generally does not regulate wastes generated by the exploration and production of natural gas and oil. RCRA specifically excludes from the definition of hazardous waste “drilling fluids, produced waters and other wastes associated with the exploration, development or production of oil, natural gas or geothermal energy.” However, legislative and regulatory initiatives have been considered from time to time that would reclassify certain natural gas and oil exploration and production wastes as “hazardous wastes,” which would make the reclassified wastes subject to much more stringent handling, disposal and clean-up requirements. If such measures were to be enacted, it could have a significant impact on our operating costs. Moreover, ordinary industrial wastes, such as paint wastes, waste solvents, laboratory wastes and waste oils, may be regulated as hazardous waste. The Clean Water Act, as amended, or CWA, and analogous state laws, impose restrictions and strict controls regarding the discharge of produced waters and other natural gas and oil waste into regulated waters. Permits must be obtained to discharge pollutants to regulated waters and to conduct construction activities in waters and wetlands. The CWA and similar state laws provide for civil, criminal and administrative penalties for any unauthorized discharges of pollutants and unauthorized discharges of reportable quantities of oil and other hazardous substances. The EPA has adopted regulations requiring certain natural gas and oil exploration and production facilities to obtain permits for storm water discharges. Costs may be associated with the treatment of wastewater or developing and implementing storm water pollution prevention plans. The Oil Pollution Act, as amended, or OPA, and regulations thereunder impose a variety of requirements on “responsible parties” related to the prevention of oil spills and liability for damages resulting from such spills in regulated waters. A “responsible party” includes the owner or operator of an onshore facility, pipeline or vessel, or the lessee or permittee of the area in which an offshore facility is located. OPA assigns liability to each responsible party for oil cleanup costs and a variety of public and private damages. Although liability limits apply in some circumstances, a party cannot take advantage of liability limits if the spill was caused by gross negligence or willful misconduct or resulted from violation of a federal safety, construction or operating regulation. If the party fails to report a spill or to cooperate fully in the cleanup, liability limits likewise do not apply. Few defenses exist to the liability imposed by OPA. OPA imposes ongoing requirements on a responsible party, including the preparation of oil spill response plans and proof of financial responsibility to cover environmental cleanup and restoration costs that could be incurred in connection with an oil spill. Oil accounted for 2% of our total production in 2018 and 2017 and 1% of our total production in 2016, although we expect this percentage to increase as we continue to develop our Southwest Appalachia assets. SWN 37 FINAL GLOSSY v6 - 4000dpi Double.pdf 21 3/25/19 5:17 PM We own or lease, and have in the past owned or leased, onshore properties that for many years have been used for or associated with the exploration for and production of natural gas and oil. Although we have utilized operating and disposal practices that were standard in the industry at the time, hydrocarbons or other wastes may have been disposed of or released on or under the properties owned or leased by us on or under other locations where such wastes have been taken for disposal. In addition, some of these properties have been operated by third parties whose treatment and disposal or release of wastes was not under our control. These properties and the wastes disposed on them may be subject to CERCLA, the Clean Water Act, RCRA and analogous state laws. Under such laws, we could be required to remove or remediate previously disposed wastes (including waste disposed of or released by prior owners or operators) or property contamination (including groundwater contamination by prior owners or operators), or to perform remedial plugging or closure operations to prevent future contamination. The Clean Air Act, as amended, restricts emissions into the atmosphere. Various activities in our operations, such as drilling, pumping and the use of vehicles, can release matter subject to regulation. We must obtain permits, typically from local authorities, to conduct various activities. Federal and state governmental agencies are looking into the issues associated with methane and other emissions from oil and natural gas activities, and further regulation could increase our costs or restrict our ability to produce. Although methane emissions are not currently regulated at the federal level, we are required to report emissions of various greenhouse gases, including methane. The Endangered Species Act and comparable state laws protect species threatened with possible extinction. Protection of threatened and endangered species may have the effect of prohibiting or delaying us from obtaining drilling and other permits and may include restrictions on road building and other activities in areas containing the affected species or their habitats. Based on the species that have been identified to date, we do not believe there are any species protected under the Endangered Species Act that would materially and adversely affect our operations at this time. Hydraulic Fracturing. We utilize hydraulic fracturing in drilling wells as a means of maximizing their productivity. It is an essential and common practice in the oil and gas industry used to stimulate production of oil, natural gas, and associated liquids from dense and deep rock formations. Hydraulic fracturing involves using water, sand, and certain chemicals to fracture the hydrocarbon-bearing rock formation to allow the flow of hydrocarbons into the wellbore. In the past several years, there has been an increased focus on environmental aspects of hydraulic fracturing practice, both in the United States and abroad. In the United States, hydraulic fracturing is typically regulated by state oil and natural gas commissions, but federal agencies have started to assert regulatory authority over certain aspects of the process. For example, the Environmental Protection Agency, or EPA, issued final rules effective as of October 15, 2012 that subject oil and gas operations (production, processing, transmission, storage and distribution) to regulation under the New Source Performance Standards, or NSPS, and National Emission Standards for Hazardous Air Pollutants, or NESHAPS programs. In May 2016, the EPA finalized additional regulations to control methane and volatile organic compound emissions from certain oil and gas equipment and operations. In September 2018, the EPA issued proposed revisions to those regulations, which, if finalized, would reduce certain obligations thereunder. The EPA also finalized pretreatment standards that would prohibit the indirect discharge of wastewater from onshore unconventional oil and gas extraction facilities to publicly owned treatment works. Based on our current operations and practices, management believes such newly promulgated rules will not have a material adverse impact on our financial position, results of operations or cash flows but these matters are subject to inherent uncertainties and management’s view may change in the future. In addition, there are certain governmental reviews either underway or proposed that focus on environmental aspects of hydraulic fracturing practices. A number of federal agencies are analyzing, or have been requested to review, a variety of environmental issues associated with hydraulic fracturing. For example, in December 2016, the EPA released its final report regarding the potential impacts of hydraulic fracturing on drinking water resources, concluding that “water cycle” activities associated with hydraulic fracturing may impact drinking water resources under certain circumstances such as water withdrawals for fracturing in times or areas of low water availability, surface spills during the management of fracturing fluids, chemicals or produced water, injection of fracturing fluids into wells with inadequate mechanical integrity, injection of fracturing fluids directly into groundwater resources, discharge of inadequately treated fracturing wastewater to surface waters and disposal or storage of fracturing wastewater in unlined pits. The results of these studies could lead federal and state governments and agencies to develop and implement additional regulations. Although the current federal administration has relaxed many regulations adopted in the latter part of the prior administration, some states in which we operate have adopted, and other states are considering adopting, regulations that could impose more stringent permitting, public disclosure, waste disposal and well construction requirements on hydraulic fracturing operations or otherwise seek to ban fracturing activities altogether. In addition to state laws, local land use restrictions, such as city ordinances, may restrict or prohibit the performance of well drilling in general and/or hydraulic fracturing in particular. In the event state, local, or municipal legal restrictions are adopted in areas where we are currently SWN 38 FINAL GLOSSY v6 - 4000dpi Double.pdf 22 3/25/19 5:17 PM conducting, or in the future plan to conduct operations, we may incur additional costs to comply with such requirements that may be significant in nature, experience delays or curtailment in the pursuit of exploration, development, or production activities, and perhaps even be precluded from the drilling and/or completion of wells. Increased regulation and attention given to the hydraulic fracturing process has led to greater opposition, including litigation, to oil and gas production activities using hydraulic fracturing techniques. Additional legislation or regulation could also lead to operational delays or increased operating costs in the production of oil, natural gas, and associated liquids including from the development of shale plays, or could make it more difficult to perform hydraulic fracturing. The adoption of additional federal, state or local laws or the implementation of regulations regarding hydraulic fracturing could potentially cause a decrease in the completion of new oil and gas wells, increased compliance costs and time, which could adversely affect our financial position, results of operations and cash flows. We refer you to the risk factor “We are subject to complex federal, state and local laws and regulations that could adversely affect the cost, manner or feasibility of conducting our operations or expose us to significant liabilities” in Item 1A of Part I of this Annual Report. In addition, concerns have been raised about the potential for seismic activity to occur from the use of underground injection control wells, a predominant method for disposing of waste water from oil and gas activities. New rules and regulations may be developed to address these concerns, possibly limiting or eliminating the ability to use disposal wells in certain locations and increasing the cost of disposal in others. We utilize third parties to dispose of waste water associated with our operations. These third parties may operate injection wells and may be subject to regulatory restrictions relating to seismicity. Greenhouse Gas Emissions. In response to findings that emissions of carbon dioxide, methane and other greenhouse gases present an endangerment to human health and the environment, the EPA has adopted regulations under existing provisions of the federal Clean Air Act that, among other things, establish Prevention of Significant Deterioration, or PSD, construction and Title V operating permit reviews for certain large stationary sources. Facilities required to obtain PSD permits for their greenhouse gas emissions also will be required to meet “best available control technology” standards that will be established on a case-by case basis. One of our subsidiaries operates compressor stations, which are facilities that are required to adhere to the PSD or Title V permit requirements. EPA rulemakings related to greenhouse gas emissions could adversely affect our operations and restrict or delay our ability to obtain air permits for new or modified sources. The EPA also has adopted rules requiring the monitoring and reporting of greenhouse gas emissions from specified onshore and offshore oil and gas production sources in the United States on an annual basis, which include certain of our operations. Although Congress from time to time has considered legislation to reduce emissions of greenhouse gases, there has not been significant activity in the form of adopted legislation to reduce greenhouse gas emissions at the federal level in recent years. In the absence of such federal climate legislation, a number of states, including states in which we operate, have enacted or passed measures to track and reduce emissions of greenhouse gases, primarily through the planned development of greenhouse gas emission inventories and regional greenhouse gas cap-and-trade programs. Most of these cap-and-trade programs require major sources of emissions or major producers of fuels to acquire and surrender emission allowances, with the number of allowances available for purchase reduced each year until the overall greenhouse gas emission reduction goal is achieved. These reductions may cause the cost of allowances to escalate significantly over time. The adoption and implementation of regulations that require reporting of greenhouse gases or otherwise limit emissions of greenhouse gases from our equipment and operations could require us to incur costs to monitor and report on greenhouse gas emissions or install new equipment to reduce emissions of greenhouse gases associated with our operations. In addition, these regulatory initiatives could drive down demand for our products by stimulating demand for alternative forms of energy that do not rely on combustion of fossil fuels that serve as a major source of greenhouse gas emissions, which could have a material adverse effect on our business, financial condition, results of operations and cash flows. At the same time, new laws and regulations are prompting power producers to shift from coal to natural gas, which is increasing demand. Further, in December 2015, over 190 countries, including the United States, reached an agreement to reduce global greenhouse gas emissions (the “Paris Agreement”). The Paris Agreement entered into effect in November 2016 after more than 70 nations, including the United States, ratified or otherwise indicated their intent to be bound by the agreement. In June 2017, President Trump announced that the United States intends to withdraw from the Paris Agreement and to seek negotiations either to reenter the Paris Agreement on different terms or a separate agreement. In August 2017, the U.S. Department of State officially informed the United Nations of the intent of the United States to withdraw from the Paris Agreement. The Paris Agreement provides for a four year exit process beginning when it took effect in November 2016, which would result in an effective exit date of November 2020. The United States’ adherence to the exit process and/or the terms on which the United States may re-enter the Paris Agreement or a separately negotiated agreement are unclear at this time. To the extent that the United States and other countries implement this agreement or impose other climate change regulations on the oil and gas industry, it could have an adverse effect on our business.

Our operations are subject to a number of federal and state laws and regulations, including the federal Occupational Safety and Health Act, or OSHA, and comparable state statutes, whose purpose is to protect the health and safety of workers. In addition, the OSHA hazard communication standard, the EPA community right-to-know regulations under Title III of the federal Superfund Amendment and Reauthorization Act and comparable state statutes require that information be maintained concerning hazardous materials used or produced in operations and that this information be provided to employees, state and local government authorities and citizens. Canada. Our activities in Canada have, to date, been limited to certain geological and geophysical activities and now are subject to a moratorium. If and when the moratorium ends and should we begin drilling and development activities in New Brunswick, we will be subject to federal, provincial and local environmental regulations. Employees As of December 31, 2018, we had 960 total employees, a decrease of 39% compared to year-end 2017, following workforce reductions and the Fayetteville Shale sale. None of our employees were covered by a collective bargaining agreement at year-end 2018. We believe that our relationships with our employees are good.

The project to extract the hydrocarbons must have commenced or the operator must be reasonably certain that it will commence the project within a reasonable time. Also referred to as “proved reserves.” For additional information, see the SEC’s definition in Rule 4-10(a) (22) of Regulation S-X, a link for which is available at the SEC’s website. “Proved reserves” See “proved natural gas, oil and NGL reserves.” “Proved undeveloped reserves” or “PUD” Proved natural gas, oil and NGL reserves that are also undeveloped natural gas, oil and NGL reserves. “PV-10” When used with respect to natural gas, oil and NGL reserves, PV-10 means the estimated future gross revenue to be generated from the production of proved reserves, net of estimated production and future development costs, using prices and costs in effect as of the date of the report or estimate, without giving effect to non-property related expenses such as general and administrative expenses, debt service and future income tax expense or to depreciation, depletion and amortization, discounted using an annual discount rate of 10%. Also referred to as “present value.” After-tax PV-10 is also referred to as “standardized measure” and is net of future income tax expense. “Reserve life index” The quotient resulting from dividing total reserves by annual production and typically expressed in years. “Reserve replacement ratio” The sum of the estimated net proved reserves added through discoveries, extensions, infill drilling and acquisitions (which may include or exclude reserve revisions of previous estimates) for a specified period of time divided by production for that same period of time. “Reservoir” A porous and permeable underground formation containing a natural accumulation of producible oil and/or gas that is confined by impermeable rock or water barriers and is individual and separate from other reservoirs. For additional information, see the SEC’s definition in Rule 4-10(a) (27) of Regulation S-X, a link for which is available at the SEC’s website. “Royalty interest” An interest in a natural gas and oil property entitling the owner to a share of natural gas, oil or NGL production free of production costs. “Tcfe” One trillion cubic feet of natural gas equivalent, with liquids converted to an equivalent volume of natural gas using the ratio of one barrel of oil to six Mcf of natural gas. “Unconventional play” A play in which the targeted reservoirs generally fall into one of three categories: tight sands, coal beds, or shales. The reservoirs tend to cover large areas and lack the readily apparent traps, seals and discrete hydrocarbon- water boundaries that typically define conventional reservoirs. These reservoirs generally require fracture stimulation treatments or other special recovery processes in order to produce economic flow rates. “Undeveloped acreage” Those leased acres on which wells have not been drilled or completed to a point that would permit the production of economic quantities of oil or gas regardless of whether such acreage contains proved reserves. For additional information, see the SEC’s definition in Item 1208(c)(4) of Regulation S-K, a link for which is available at the SEC’s website. “Undeveloped natural gas, oil and NGL reserves” Undeveloped natural gas, oil and NGL reserves are reserves of any category that are expected to be recovered from new wells on undrilled acreage, or from existing wells where a relatively major expenditure is required for recompletion. Also referred to as “undeveloped reserves.” For additional information, see the SEC’s definition in Rule 4-10(a) (31) of Regulation S-X, a link for which is available at the SEC’s website. “Undeveloped reserves” See “undeveloped natural gas, oil and NGL reserves.” SWN 44 FINAL GLOSSY v6 - 4000dpi Double.pdf 28 3/25/19 5:17 PM “Wells to sales” Wells that have been placed on sales for the first time. “Working interest” An operating interest that gives the owner the right to drill, produce and conduct operating activities on the property and to receive a share of production. “Workovers” Operations on a producing well to restore or increase production. “WTI” West Texas Intermediate, the benchmark oil price in the United States. ITEM 1A. RISK FACTORS You should carefully consider the following risk factors in addition to the other information included in this Annual Report. Each of these risk factors could adversely affect our business, operating results and financial condition, as well as adversely affect the value of an investment in our common stock. Natural gas, oil and NGL prices greatly affect our revenues and thus profits, liquidity, growth, ability to repay our debt and the value of our assets. Our revenues, profitability, liquidity, growth, ability to repay our debt and the value of our assets greatly depend on prices for natural gas, oil and NGLs. The markets for these commodities are volatile, and we expect that volatility to continue. The prices of natural gas, oil and NGLs fluctuate in response to changes in supply and demand (global, regional and local), transportation costs, market uncertainty and other factors that are beyond our control. Short- and long-term prices are subject to a myriad of factors such as: • • • • • overall demand, including the relative cost of competing sources of energy or fuel; overall supply, including costs of production; the availability, proximity and capacity of pipelines, other transportation facilities and gathering, processing and storage facilities; regional basis differentials; national and worldwide economic and political conditions; • weather conditions and seasonal trends; • • government regulations, such as regulation of natural gas transportation and price controls; inventory levels; and • market perceptions of future prices, whether due to the foregoing factors or others. For example, in 2017 and 2018, the NYMEX settlement price for natural gas ranged from a low of $2.63 per MMBtu in March 2017 to a high of $4.72 per MMBtu in December 2018, and during this period our production was 89% and 85% natural gas, respectively. NGLs represent a growing part of our business, and in the same period prices for ethane and propane, our two principal NGL products, ranged from $1.81 per Bbl in December 2017 to $14.64 per Bbl in September 2018 and $16.91 per Bbl in June 2017 to $36.35 per Bbl in December 2017, respectively. Although we hedge a large portion of our production against changing prices, derivatives do not protect all our future volumes, may result in our forgoing profit opportunities if markets rise and, for NGLs, are not always available for substantial periods into the future. In 2018, we paid $94 million, net of amounts we received, in settlement of hedging arrangements. Lower natural gas, oil and NGL prices directly reduce our revenues and thus our operating income and cash flow. Lower prices also reduce the projected profitability of further drilling and therefore are likely to reduce our drilling activity, which in turn means we will have fewer wells on production in the future. Lower prices also reduce the value of our assets, both by a direct reduction in what the production would be worth and by making some properties uneconomic, resulting in impairments to the recorded value of our reserves and non-cash charges to earnings. For example, in 2016, we reported non- cash impairment charges on our natural gas and oil properties totaling $2.3 billion, primarily resulting from decreases in trailing 12-month average first-day-of-the-month natural gas prices throughout 2016, as compared to 2015, and the impairment of certain undeveloped leasehold interests. Further impairments in subsequent periods could occur if the trailing 12-month commodity prices decrease as compared to the average used in prior periods. SWN 45 FINAL GLOSSY v6 - 4000dpi Double.pdf 29 3/25/19 5:17 PM As of December 31, 2018, we had $2.3 billion of debt outstanding, consisting principally of senior notes maturing in various increments from 2020 to 2027, and no borrowings under our revolving credit facility. At current commodity price levels, our net cash flow from operations is substantially higher than our interest obligations under this debt, but significant drops in realized prices could affect our ability to pay our current obligations or refinance our debt as it becomes due. Moreover, general industry conditions may make it difficult or costly to refinance increments of this debt as it matures. Although our indentures do not contain significant covenants restricting our operations and other activities, our bank credit agreements contain financial covenants with which we must comply. We refer you to the risk factor “Our current and future levels of indebtedness may adversely affect our results and limit our growth.” Our inability to pay our current obligations or refinance our debt as it becomes due could have a material and adverse effect on our company. The drop in prices since 2014 has reduced our revenues, profits and cash flow, caused us to record significant asset impairments and led us to reduce both our level of capital investing and our workforce, which has caused us to incur significant expenses relating to employee terminations. Further price decreases could have similar consequences. Similarly, a rise in prices to levels experienced before 2015 could significantly increase our revenues, profits and cash flow, which could be used to expand capital investments. Significant capital investment is required to replace our reserves and conduct our business. Our activities require substantial capital investment. We intend to fund our future capital investing through net cash flows from operations, net of changes in working capital, supplemented on occasion by funds earmarked from the net proceeds of significant transactions, such as the Fayetteville Shale sale. Our ability to generate operating cash flow is subject to many of the risks and uncertainties that exist in our industry, some of which we may not be able to anticipate at this time. Future cash flows from operations are subject to a number of risks and variables, such as the level of production from existing wells, prices of natural gas, oil and NGLs, our success in developing and producing new reserves and the other risk factors discussed herein. If we are unable to fund capital investing, we could experience a further reduction in drilling new wells and acquiring new acreage, a loss of properties and a decline in our cash flow from operations and natural gas, oil and NGL production and reserves. If we are not able to replace reserves, our production levels and thus our revenues and profits may decline. Production levels from existing wells decline over time, and drilling new wells requires an inventory of leases and other rights with reserves that have not yet been drilled. Our future success depends largely upon our ability to find, develop or acquire additional natural gas, oil and NGL reserves that are economically recoverable. Unless we replace the reserves we produce through successful development, acquisition or exploration activities, our proved reserves and production will decline over time. Identifying and exploiting new reserves requires significant capital investment and successful drilling operations. Thus, our future natural gas, oil and NGL reserves and production, and therefore our revenues and profits, are highly dependent on our level of capital investments, our success in efficiently developing our current reserves and economically finding or acquiring additional recoverable reserves. Our business depends on access to natural gas, oil and NGL transportation systems and facilities. The marketability of our natural gas, oil and NGL production depends in large part on the operation, availability, proximity, capacity and expansion of transportation systems and facilities owned by third parties. For example, we can provide no assurance that sufficient transportation capacity will exist for expected production from the Appalachian Basin or that we will be able to obtain sufficient transportation capacity on economic terms. During the past three years, several planned pipelines intended to service production in the Northeast United States have had their in-service dates delayed due to regulatory delays and litigation. Producers compete by lowering their sales prices, resulting in the locational differences from NYMEX pricing. Further, a lack of available capacity on transportation systems and facilities or delays in their planned expansions could result in the shut-in of producing wells or the delay or discontinuance of drilling plans for properties. A lack of availability of these systems and facilities for an extended period of time could negatively affect our revenues. In addition, we have entered into contracts for firm transportation and any failure to renew those contracts on the same or better commercial terms could increase our costs and our exposure to the risks described above. A downgrade in our credit rating could negatively impact our cost of and ability to access capital and our liquidity. Actual or anticipated changes or downgrades in our credit ratings, including any announcement that our ratings are under review for a downgrade, could impact our ability to access debt markets in the future to refinance existing debt or obtain additional funds, affect the market value of our senior notes and increase our corporate borrowing costs. Such ratings are SWN 46 FINAL GLOSSY v6 - 4000dpi Double.pdf 30 3/25/19 5:17 PM limited in scope, and do not address all material risks relating to us, but rather reflect only the view of each rating agency of the likelihood we will be able to repay our debt at the time the rating is issued. An explanation of the significance of each rating may be obtained from the applicable rating agency. As of February 26, 2019, our long-term issuer ratings were Ba2 by Moody’s, BB by Standard and Poor’s and BB by Fitch Investor Services. There can be no assurance that such credit ratings will remain in effect for any given period of time or that such ratings will not be lowered, suspended or withdrawn entirely by the rating agencies, if, in each rating agency’s judgment, circumstances so warrant. Actual downgrades in our credit ratings may also impact our liquidity. Many of our existing commercial contracts contain, and future commercial contracts may contain, provisions permitting the counterparty to require increased security upon the occurrence of a downgrade in our credit rating. Providing additional security, such as posting letters of credit, could reduce our available cash or our liquidity under our revolving credit facility for other purposes. We had $112 million of letters of credit outstanding at December 31, 2018. The amount of additional financial assurance would depend on the severity of the downgrade from the credit rating agencies, and a downgrade could result in a decrease in our liquidity. Strategic determinations, including the allocation of capital and other resources to strategic opportunities, are challenging in the face of shifting market conditions, and our failure to appropriately allocate capital and resources among our strategic opportunities may adversely affect our financial condition and reduce our future growth rate. We necessarily must consider future price and cost environments when deciding how much capital we are likely to have available from net cash flow and how best to allocate it. Our current philosophy is to generally operate within cash flow from operations net of changes in working capital and to invest capital only in projects projected to generate a PVI of 1.3 or greater, allocating generally to the highest PVI projects. Volatility in prices and potential errors in estimating costs, reserves or timing of production of the reserves could result in uneconomic projects or economic projects generating less than 1.3 PVI. Certain of our undeveloped assets are subject to leases that will expire over the next several years unless production is established on units containing the acreage. Approximately 13,123 and 43,092 net acres of our Northeast Appalachia and Southwest Appalachia acreage, respectively, will expire in the next three years if we do not drill successful wells to develop the acreage or otherwise take action to extend the leases. Our ability to drill wells depends on a number of factors, including certain factors that are beyond our control, such as the ability to obtain permits on a timely basis or to compel landowners or lease holders on adjacent properties to cooperate. Further, we may not have sufficient capital to drill all the wells necessary to hold the acreage without increasing our debt levels, or given price projections at the time, drilling may not be estimated to achieve a PVI of at least 1.3 or be judged to be the best use of our capital. To the extent we do not drill the wells, our rights to acreage can be lost. Natural gas and oil drilling and producing and transportation operations can be hazardous and may expose us to liabilities. Drilling and production operations are subject to many risks, including well blowouts, cratering and explosions, pipe failures, fires, formations with abnormal pressures, uncontrollable flows of oil, natural gas, brine or well fluids, severe weather, natural disasters, groundwater contamination and other environmental hazards and risks. Some of these risks or hazards could materially and adversely affect our revenues and expenses by reducing or shutting in production from wells, loss of equipment or otherwise negatively impacting the projected economic performance of our prospects. If any of these risks occurs, we could sustain substantial losses as a result of: • • • • • • injury or loss of life; severe damage to or destruction of property, natural resources or equipment; pollution or other environmental damage; clean-up responsibilities; regulatory investigations and administrative, civil and criminal penalties; and injunctions resulting in limitation or suspension of operations. For our non-operated properties, we depend on the operator for operational and regulatory compliance. FINAL GLOSSY v6 - 4000dpi Double.pdf 31 3/25/19 5:17 PM SWN 47 We rely on third parties to transport our production to markets. Their operations, and thus our ability to reach markets, are subject to all of the risks and operational hazards inherent in transporting natural gas and ethane and natural gas compression, including: • damages to pipelines, facilities and surrounding properties caused by third parties, severe weather, natural disasters, including hurricanes, and acts of terrorism; • maintenance, repairs, mechanical or structural failures; • • • damages to, loss of availability of and delays in gaining access to interconnecting third-party pipelines; disruption or failure of information technology systems and network infrastructure due to various causes, including unauthorized access or attack; and leaks of natural gas or ethane as a result of the malfunction of equipment or facilities. A material event such as those described above could expose us to liabilities, monetary penalties or interruptions in our business operations. Although we may maintain insurance against some, but not all, of the risks described above, our insurance may not be adequate to cover casualty losses or liabilities, and our insurance does not cover penalties or fines that may be assessed by a governmental authority. Also, in the future we may not be able to obtain insurance at premium levels that justify its purchase. Our current and future levels of indebtedness may adversely affect our results and limit our growth. At December 31, 2018, we had long-term indebtedness of $2.3 billion. The terms of the indentures governing our outstanding senior notes, our credit facilities, and the lease agreements relating to our drilling rigs, other equipment and headquarters building, which we collectively refer to as our “financing agreements,” impose restrictions on our ability and, in some cases, the ability of our subsidiaries to take a number of actions that we may otherwise desire to take, which may include, without limitation, one or more of the following: • • incurring additional debt; redeeming stock or redeeming certain debt; • making certain investments; • • creating liens on our assets; and selling assets. The revolving credit facility we entered into in April 2018 (our “revolving credit facility”) contains customary representations, warranties and covenants including, among others, the following covenants: • • • • a prohibition against incurring debt, subject to permitted exceptions; a restriction on creating liens on assets, subject to permitted exceptions; restrictions on mergers and asset dispositions; restrictions on use of proceeds, investments, transactions with affiliates, or change of principal business; and • maintenance of the following financial covenants, commencing with the fiscal quarter ended June 30, 2018: 1. Minimum current ratio of no less than 1.00 to 1.00, whereby current ratio is defined as the Company’s consolidated current assets (including unused commitments under the credit agreement, but excluding non-cash derivative assets) to consolidated current liabilities (excluding non-cash derivative obligations and current maturities of long-term debt). 2. Maximum total net leverage ratio of no less than (i) with respect to each fiscal quarter ending during the period from June 30, 2018 through March 31, 2019, 4.50 to 1.00, (ii) with respect to each fiscal quarter ending during the period from June 30, 2019 through March 31, 2020, 4.25 to 1.00, and (iii) with respect to each fiscal quarter ending on or after June 30, 2020, 4.00 to 1.00. Total net leverage ratio is defined as total debt less cash on hand (up to the lesser of 10% of credit limit or $150 million) divided by consolidated EBITDAX for the last four consecutive quarters. EBITDAX, as defined in our revolving credit facility, excludes the effects of interest expense, depreciation, depletion and amortization, income tax, any non-cash impacts from impairments, certain non-cash hedging activities, stock-based compensation expense, non-cash gains or losses on asset sales, unamortized issuance cost, unamortized debt discount and certain restructuring costs. SWN 48 FINAL GLOSSY v6 - 4000dpi Double.pdf 32 3/25/19 5:17 PM In the fourth quarter of 2018, we entered into hedges that, when added to then-existing hedges including hedges put in place as part of the Fayetteville Shale sale that the buyer was obligated to assume at closing of that sale, exceeded a cap on hedges for the month of December 2018 under a covenant under our credit agreement. In conjunction with the closing, the buyer paid for the settlement of the December 2018 hedges it was to assume. The lenders have subsequently waived all matters associated with this default. Otherwise, as of December 31, 2018, we were in compliance with all of the remaining covenants of our revolving credit facility in all material respects. Although we do not anticipate any future violations of our financial covenants, our ability to comply with these covenants depends in part on the success of our exploration and development program and upon factors beyond our control, such as the market prices for natural gas, oil and NGLs. Our level of indebtedness and off-balance sheet obligations, and the covenants contained in our financing agreements, could have important consequences for our operations, including: • • • • requiring us to dedicate a substantial portion of our cash flow from operations to required payments, thereby reducing the availability of cash flow for working capital, capital investing and other general business activities; limiting our ability to obtain additional financing in the future for working capital, capital investing, acquisitions and general corporate and other activities; limiting our flexibility in planning for, or reacting to, changes in our business and the industry in which we operate; and detracting from our ability to successfully withstand a downturn in our business or the economy generally. Any significant reduction in our borrowing base under our revolving credit facility as a result of periodic borrowing base redeterminations or otherwise may negatively impact our ability to fund our operations, and we may not have sufficient funds to repay borrowings under our revolving credit facility if required as a result of a borrowing base redetermination. The amount we may borrow under our revolving credit facility is capped at the lower of our commitment and a “borrowing base” determined from time to time by the lenders based on our reserves, market conditions and other factors. As of December 31, 2018, the borrowing base was $2.1 billion, which is above the total current commitments of $2.0 billion. The borrowing base is subject to scheduled semiannual and other elective collateral borrowing base redeterminations based on our natural gas, oil and NGL reserves and other factors. As of December 31, 2018, we had no outstanding borrowings under our revolving credit facility, though we may elect to borrow under that facility in the future. As of December 31, 2018, we had $112 million of letters of credit issued under the credit facility and unused borrowing capacity was approximately $1.9 billion. Any significant reduction in our borrowing base as a result of borrowing base redeterminations or otherwise may negatively impact our liquidity and our ability to fund our operations and, as a result, may have a material adverse effect on our financial position, results of operation and cash flow. Further, if the outstanding borrowings under our revolving credit facility were to exceed the borrowing base as a result of any such redetermination, we would be required to repay the excess with short notice. We may not have sufficient funds to make such repayments. If we do not have sufficient funds and we are otherwise unable to negotiate renewals of our borrowings or arrange new financing, we may have to sell significant assets. Any such sale could have a material adverse effect on our business and financial results. Our ability to comply with the covenants and other restrictions in our financing agreements may be affected by events beyond our control, including prevailing economic and financial conditions. Failure to comply with the covenants and other restrictions could lead to an event of default and the acceleration of our obligations under our senior notes, credit facilities or other financing agreements, and in the case of the lease agreements for drilling rigs, compressors and pressure pumping equipment, loss of use of the equipment. In particular, the occurrence of risks identified elsewhere in this section, such as declines in commodity prices, increases in basis differentials and inability to access markets, could reduce our profits and thus the cash we have to fulfill our financial obligations. If we are unable to satisfy our obligations with cash on hand, we could attempt to refinance such debt, sell assets or repay such debt with the proceeds from an equity offering. We cannot assure that we will be able to generate sufficient cash flow to pay the interest on our debt, to meet our lease obligations, or that future borrowings, equity financings or proceeds from the sale of assets will be available to pay or refinance such debt or obligations. The terms of our financing agreements may also prohibit us from taking such actions. Factors that will affect our ability to raise cash through an offering of our capital stock, a refinancing of our debt or a sale of assets include financial market conditions and our market value and operating performance at the time of such offering or other financing. We cannot assure that any such proposed offering, refinancing or sale of assets can be successfully completed or, if completed, that the terms will be favorable to us. SWN 49 FINAL GLOSSY v6 - 4000dpi Double.pdf 33 3/25/19 5:17 PM We have entered into long-term gathering and transportation contracts and have made significant investments in oilfield service businesses, including our drilling rigs, water infrastructure and pressure pumping equipment, to lower costs and secure inputs for our operations and transportation for our production. If our development and production activities are curtailed or disrupted, we may not recover our investment in these activities, which could adversely impact our results of operations. In addition, our continued expansion of these operations may adversely impact our relationships with third- party providers. We have entered into gathering agreements in producing areas and multiple long-term firm transportation agreements relating to natural gas volumes from all our producing areas. As of December 31, 2018, our aggregate demand charge commitments under these firm transportation agreements and gathering agreements were approximately $8.8 billion. If our development programs fail to produce sufficient quantities of natural gas and ethane within expected timeframes, we could be forced to pay demand or other charges for transportation on pipelines and gathering systems that we would not be using. We also have made investments to meet certain of our field services’ needs, including establishing our own drilling rig operation, water transportation system in Southwest Appalachia and pressure pumping capability. If our level of operations is reduced for a long period, we may not be able to recover these investments. Further, our presence in these service and supply sectors, including competing with them for qualified personnel and supplies, may have an adverse effect on our relationships with our existing third-party service and resource providers or our ability to secure these services and resources from other providers. Our business depends on the availability of water and the ability to dispose of water. Limitations or restrictions on our ability to obtain or dispose of water may have an adverse effect on our financial condition, results of operations and cash flows. Water is an essential component of drilling and hydraulic fracturing processes. Limitations or restrictions on our ability to secure sufficient amounts of water, or to dispose of or recycle water after use, could adversely impact our operations. In some cases, water may need to be obtained from new sources and transported to drilling sites, resulting in increased costs. Moreover, the introduction of new environmental initiatives and regulations related to water acquisition or waste water disposal, including produced water, drilling fluids and other wastes associated with the exploration, development or production of hydrocarbons, could limit or prohibit our ability to utilize hydraulic fracturing or waste water injection control wells. In addition, concerns have been raised about the potential for seismic activity to occur from the use of underground injection control wells, a predominant method for disposing of waste water from oil and gas activities. New rules and regulations may be developed to address these concerns, possibly limiting or eliminating the ability to use disposal wells in certain locations and increasing the cost of disposal in others. We utilize third parties to dispose of waste water associated with our operations. These third parties may operate injection wells and may be subject to regulatory restrictions relating to seismicity. Compliance with environmental regulations and permit requirements governing the withdrawal, storage and use of water necessary for hydraulic fracturing of wells or the disposal of water may increase our operating costs or may cause us to delay, curtail or discontinue our exploration and development plans, which could have a material adverse effect on our business, financial condition, results of operations and cash flows. Our producing properties are concentrated in the Appalachian Basin, making us vulnerable to risks associated with operating in limited geographic areas. Our producing properties currently are geographically concentrated in the Appalachian Basin in Pennsylvania and West Virginia. At December 31, 2018, nearly 100% of our total estimated proved reserves were attributable to properties located in the Appalachian Basin. As a result of this concentration in one primary region, we may be disproportionately exposed to the impact of regional supply and demand factors, delays or interruptions of production from wells in this area caused by governmental regulation, state politics, processing or transportation capacity constraints, market limitations, availability of equipment and personnel, water shortages or interruption of the processing or transportation of natural gas, oil or NGLs. Competition in the oil and natural gas industry is intense, making it more difficult for us to market natural gas, oil and NGLs, to secure trained personnel and appropriate services, to obtain additional properties and to raise capital. Our cost of operations is highly dependent on third-party services, and as activity in our industry increases, competition for these services may increase. Similarly, we must have trained, qualified personnel, and as commodity prices rise, competition for this talent also increases. Our ability to acquire and develop reserves in the future will depend on our ability SWN 50 FINAL GLOSSY v6 - 4000dpi Double.pdf 34 3/25/19 5:17 PM to evaluate and select suitable properties and to consummate transactions in a highly competitive environment for acquiring properties, marketing natural gas, oil and NGLs and securing trained personnel. Also, there is substantial competition for capital available for investment in the oil and gas industry. Certain of our competitors may possess and employ financial, technical and personnel resources greater than ours. Those companies may be able to pay more for personnel, property and services and to attract capital at lower rates. This may become more likely if prices for oil and NGLs recover faster than prices for natural gas, as natural gas comprises a greater percentage of our overall production than it does for most of the companies with whom we compete for talent. Climate change legislation or regulations governing the emissions of greenhouse gases could result in increased operating costs and reduce demand for the natural gas, oil and NGLs we produce, and concern in financial and investment markets over greenhouse gasses and fossil fuel production could adversely affect our access to capital and the price of our common stock. In response to findings that emissions of carbon dioxide, methane and other greenhouse gases present an endangerment to human health and the environment, the EPA has adopted regulations under existing provisions of the federal Clean Air Act that, among other things, establish Prevention of Significant Deterioration, or PSD, construction and Title V operating permit reviews for certain large stationary sources. Facilities required to obtain PSD permits for their greenhouse gas emissions also will be required to meet “best available control technology” standards that will be established on a case-by-case basis. EPA rulemakings related to greenhouse gas emissions could adversely affect our operations and restrict or delay our ability to obtain air permits for new or modified sources. The EPA also has adopted rules requiring the monitoring and reporting of greenhouse gas emissions from specified onshore and offshore natural gas and oil production sources in the United States on an annual basis, which include certain of our operations. In May 2016, the EPA finalized additional regulations to control methane and volatile organic compound emissions from certain oil and gas equipment and operations. However, in September 2018, the EPA issued proposed revisions to those regulations, which, if finalized, would reduce certain obligations thereunder. Although Congress from time to time has considered legislation to reduce emissions of greenhouse gases, there has not been significant activity in the form of adopted legislation to reduce greenhouse gas emissions at the federal level in recent years. In the absence of such federal climate legislation, a number of states, including states in which we operate, have enacted or passed measures to track and reduce emissions of greenhouse gases, primarily through the planned development of greenhouse gas emission inventories and regional greenhouse gas cap-and-trade programs. Most of these cap-and-trade programs require major sources of emissions or major producers of fuels to acquire and surrender emission allowances, with the number of allowances available for purchase reduced each year until the overall greenhouse gas emission reduction goal is achieved. These reductions may cause the cost of allowances to escalate significantly over time. The adoption and implementation of regulations that require reporting of greenhouse gases or otherwise limit emissions of greenhouse gases from our equipment and operations could require us to incur costs to monitor and report on greenhouse gas emissions or install new equipment to reduce emissions of greenhouse gases associated with our operations. In addition, these regulatory initiatives could drive down demand for our products by stimulating demand for alternative forms of energy that do not rely on combustion of fossil fuels that serve as a major source of greenhouse gas emissions, which could have a material adverse effect on our business, financial condition, results of operations and cash flows. At the same time, new laws and regulations are prompting power producers to shift from coal to natural gas, which is increasing demand. In December 2015, over 190 countries, including the United States, reached an agreement to reduce global greenhouse gas emissions (the “Paris Agreement”). The Paris Agreement entered into force in November 2016 after more than 70 nations, including the United States, ratified or otherwise indicated their intent to be bound by the agreement. In June 2017, President Trump announced that the United States intends to withdraw from the Paris Agreement and to seek negotiations either to reenter the Paris Agreement on different terms or a separate agreement. In August 2017, the U.S. Department of State officially informed the United Nations of the intent of the United States to withdraw from the Paris Agreement. The Paris Agreement provides for a four year exit process beginning when it took effect in November 2016, which would result in an effective exit date of November 2020. The United States’ adherence to the exit process and/or the terms on which the United States may re-enter the Paris Agreement or a separately negotiated agreement are unclear at this time. To the extent that the United States and other countries implement this agreement or impose other climate change regulations on the oil and natural gas industry, or that investors insist on compliance regardless of legal requirements, it could have an adverse effect on our business. Separate from actual and possible governmental action, certain financial institutions have announced policies to cease investing or to divest investments in companies, such as ours, that produce fossil fuels, and some banks have announced they no longer will lend to companies in this sector. To date these represent small fractions of overall sources of equity and debt, SWN 51 FINAL GLOSSY v6 - 4000dpi Double.pdf 35 3/25/19 5:17 PM but that fraction could grow and thus affect our access to capital. Moreover, some equity investors are expressing concern over these matters and may prompt companies in our industry to adopt more costly practices even absent governmental action. Although we believe our practices result in low emission rates for methane and other greenhouse gases, complying with investor sentiment may require modifications to our practices, which could increase our capital and operating expenses. Volatility in the financial markets or in global economic factors could adversely impact our business and financial condition. Our business may be negatively impacted by adverse economic conditions or future disruptions in global financial markets. Included among these potential negative impacts are reduced energy demand and lower commodity prices, increased difficulty in collecting amounts owed to us by our customers, reduced access to credit markets and the risks related to the discontinuation of LIBOR and other reference rates, including increased expenses and litigation and the effectiveness of interest rate hedge strategies. Our ability to access the capital markets may be restricted at a time when we would like, or need, to raise financing. If financing is not available when needed, or is available only on unfavorable terms, we may be unable to implement our business plans or otherwise take advantage of business opportunities or respond to competitive pressures. Any changes in U.S. trade policy could trigger retaliatory actions by affected countries, resulting in “trade wars,” in increased costs for materials necessary for our industry along with other goods imported into the United States, which may reduce customer demand for these products if the parties having to pay those tariffs increase their prices, or in trading partners limiting their trade with the United States. If these consequences are realized, the volume of economic activity in the United States, including growth in sectors that utilize our products, may be materially reduced along with a reduction in the potential export of our products. Such a reduction may materially and adversely affect commodity prices, our sales and our business. We, our service providers and our customers are subject to complex federal, state and local laws and regulations that could adversely affect the cost, manner or feasibility of conducting our operations or expose us to significant liabilities. Our development and production operations and the transportation of our products to market are subject to complex and stringent federal, state and local laws and regulations, including those governing environmental protection, the occupational health and safety aspects of our operations, the discharge of materials into the environment, and the protection of certain plant and animal species. See “Other – Environmental Regulation” in Item 1 of Part I of this Annual Report for a description of the laws and regulations that affect us. These laws and regulations require us, our service providers and our customers to obtain and maintain numerous permits, approvals and certificates from various federal, state and local governmental authorities. Environmental regulations may restrict the types, quantities and concentration of materials that can be released into the environment in connection with drilling and production activities, limit or prohibit drilling or transportation activities on certain lands lying within wilderness, wetlands, archeological sites and other protected areas, and impose substantial liabilities for pollution resulting from our operations and those of our service providers and customers. In addition, we or they may experience delays in obtaining or be unable to obtain required permits, including as a result of government shutdowns, which may delay or interrupt our or their operations and limit our growth and revenues. Failure to comply with laws and regulations can trigger a variety of administrative, civil and criminal enforcement measures, including investigatory actions, the assessment of monetary penalties, the imposition of remedial requirements, or the issuance of orders or judgments limiting or enjoining future operations. Strict liability or joint and several liability may be imposed under certain laws, which could cause us to become liable for the conduct of others or for consequences of our own actions. Moreover, our costs of compliance with existing laws could be substantial and may increase or unforeseen liabilities could be imposed if existing laws and regulations are revised or reinterpreted, or if new laws and regulations become applicable to our operations. If we are not able to recover the increased costs through insurance or increased revenues, our business, financial condition, results of operations and cash flows could be adversely affected. Our proved natural gas, oil and NGL reserves are estimates that include uncertainties. Any material changes to these uncertainties or underlying assumptions could cause the quantities and net present value of our reserves to be overstated or understated. As described in more detail under “Critical Accounting Policies and Estimates – Natural Gas and Oil Properties” in Item 7 of Part II of this Annual Report, our reserve data represents the estimates of our reservoir engineers made under the supervision of our management, and our reserve estimates are audited each year by Netherland, Sewell & Associates, Inc., or NSAI, an independent petroleum engineering firm. Reserve engineering is a subjective process of estimating underground accumulations of natural gas, oil and NGLs that cannot be measured in an exact manner. The process of estimating quantities of proved reserves is complex and inherently imprecise, and the reserve data included in this document are only estimates. The process relies on interpretations of available geologic, geophysical, engineering and production data. The extent, quality SWN 52 FINAL GLOSSY v6 - 4000dpi Double.pdf 36 3/25/19 5:17 PM and reliability of this technical data can vary. The process also requires certain economic assumptions, some of which are mandated by the SEC, such as historic natural gas, oil and NGL prices. Additional assumptions include drilling and operating expenses, capital investing, taxes and availability of funds. Furthermore, different reserve engineers may make different estimates of reserves and cash flows based on the same data. Results of drilling, testing and production subsequent to the date of an estimate may justify revising the original estimate. Accordingly, initial reserve estimates often vary from the quantities of natural gas, oil and NGLS that are ultimately recovered, and such variances may be material. Any significant variance could reduce the estimated quantities and present value of our reserves. You should not assume that the present value of future net cash flows from our proved reserves is the current market value of our estimated natural gas, oil and NGL reserves. In accordance with SEC requirements, we base the estimated discounted future net cash flows from our proved reserves on the preceding 12-month average natural gas, oil and NGL index prices, calculated as the unweighted arithmetic average for the first day of the month price for each month and costs in effect on the date of the estimate, holding the prices and costs constant throughout the life of the properties. Actual future prices and costs may differ materially from those used in the net present value estimate, and future net present value estimates using then current prices and costs may be significantly less than the current estimate. In addition, the 10% discount factor we use when calculating discounted future net cash flows for reporting requirements in compliance with the applicable accounting standards may not be the most appropriate discount factor based on interest rates in effect from time to time and risks associated with us or the oil and gas industry in general. Our commodity price risk management and measurement systems and economic hedging activities might not be effective and could increase the volatility of our results. We currently seek to hedge the price of a significant portion of our estimated production, through swaps, collars, floors and other derivative instruments. The systems we use to quantify commodity price risk associated with our businesses might not always be effective. Further, such systems do not in themselves manage risk, particularly risks outside of our control, and adverse changes in energy commodity market prices, volatility, adverse correlation of commodity prices, the liquidity of markets, changes in interest rates and other risks discussed in this report might still adversely affect our earnings, cash flows and balance sheet under applicable accounting rules, even if risks have been identified. Furthermore, no single hedging arrangement can adequately address all risks present in a given contract. For example, a forward contract that would be effective in hedging commodity price volatility risks would not hedge the contract’s counterparty credit or performance risk. Therefore, unhedged risks will always continue to exist. Our use of derivatives, through which we attempt to reduce the economic risk of our participation in commodity markets could result in increased volatility of our reported results. Changes in the fair values (gains and losses) of derivatives that qualify as hedges under GAAP to the extent that such hedges are not fully effective in offsetting changes to the value of the hedged commodity, as well as changes in the fair value of derivatives that do not qualify or have not been designated as hedges under GAAP, must be recorded in our income. This creates the risk of volatility in earnings even if no economic impact to us has occurred during the applicable period. To the extent we cap or lock prices at specific levels, we would also forgo the ability to realize the higher revenues that would be realized should prices increase. The impact of changes in market prices for natural gas, oil and NGLs on the average prices paid or received by us may be reduced based on the level of our hedging activities. These hedging arrangements may limit or enhance our margins if the market prices for oil, natural gas or NGLs were to change substantially from the price established by the hedges. In addition, our hedging arrangements expose us to the risk of financial loss if our production volumes are less than expected. We may be unable to dispose of assets on attractive terms, and may be required to retain liabilities for certain matters. Various factors could materially affect our ability to dispose of assets if and when we decide to do so, including the availability of purchasers willing to purchase the assets at prices acceptable to us, particularly in times of reduced and volatile commodity prices. Sellers typically retain certain liabilities for certain matters. The magnitude of any such retained liability or indemnification obligation may be difficult to quantify at the time of the transaction and ultimately may be material. Also, as is typical in divestiture transactions, third parties may be unwilling to release us from guarantees or other credit support provided prior to the sale of the divested assets. As a result, after a sale, we may remain secondarily liable for the obligations guaranteed or supported to the extent that the buyer of the assets fails to perform these obligations. SWN 53 FINAL GLOSSY v6 - 4000dpi Double.pdf 37 3/25/19 5:17 PM The implementation of derivatives legislation could have an adverse effect on our ability to use derivative instruments to reduce the effect of commodity price, interest rate and other risks associated with our business. The Dodd-Frank Act established federal oversight and regulation of the over-the-counter (“OTC”) derivatives market and entities, including us, which participate in that market. The Dodd-Frank Act requires the CFTC, the SEC, and other regulatory authorities to promulgate rules and regulations implementing the Dodd-Frank Act. Although the CFTC has finalized most of its regulations under the Dodd-Frank Act, it continues to review and refine its initial rulemakings through additional interpretations and supplemental rulemakings. As a result, it is not possible at this time to predict the ultimate effect of the rules and regulations on our business and while most of the regulations have been adopted, any new regulations or modifications to existing regulations may increase the cost of derivative contracts, limit the availability of derivatives to protect against risks that we encounter, reduce our ability to monetize or restructure our existing derivative contracts, and increase our exposure to less creditworthy counterparties. If we reduce our use of derivatives as a result of the Dodd-Frank Act and the regulations thereunder, our results of operations may become more volatile and our cash flows may be less predictable, which could adversely affect our ability to plan for and fund capital investing. In December 2016, the CFTC re-proposed new rules that would place federal limits on positions in certain core futures and equivalent swaps contracts for or linked to certain physical commodities, subject to exceptions for certain bona fide hedging transactions and finalized a companion rule on aggregation of positions among entities under common ownership or control. If finalized, the position limits rule may have an impact on our ability to hedge our exposure to certain enumerated commodities. The CFTC has designated certain interest rate swaps and credit default swaps for mandatory clearing and mandatory trading on designated contract markets or swap execution facilities. The CFTC may designate additional classes of swaps as subject to the mandatory clearing requirement in the future, but has not yet proposed rules designating any other classes of swaps, including physical commodity swaps, for mandatory clearing. The CFTC and prudential banking regulators also adopted mandatory margin requirements on uncleared swaps between swap dealers and certain other counterparties. The margin requirements are currently effective with respect to certain market participants and will be phased in over time with respect to other market participants, based on the level of an entity’s swaps activity. We expect to qualify for and rely upon an end-user exception from the mandatory clearing and trade execution requirements for swaps entered to hedge our commercial risks. We also should qualify for an exception from the uncleared swaps margin requirements. However, the application of the mandatory clearing and trade execution requirements and the uncleared swaps margin requirement to other market participants, such as swap dealers, may adversely affect the cost and availability of the swaps that we use for hedging. Further regulations relating to and interpretations of the recently enacted Tax Cuts and Jobs Act may have a material impact on our financial condition and results of operations. On December 22, 2017, President Trump signed into law H.R. 1 (commonly referred to as the “Tax Cuts and Jobs Act,” or the “Tax Reform Act”), a comprehensive tax reform bill that significantly reforms the Internal Revenue Code of 1986, as amended. The Tax Reform Act, among other things, contains significant changes to corporate taxation, including a permanent reduction of the corporate income tax rate, a partial limitation on the deductibility of business interest expense, limitation of the deduction for certain net operating losses to 80% of current year taxable income for tax years 2018 and beyond, an indefinite net operating loss carryforward, immediate deductions for certain new investments instead of deductions for depreciation expense over time and the modification or repeal of many business deductions and credits. The Treasury Department and the Internal Revenue Service continue to release regulations relating to and interpretive guidance of the legislation contained in the Tax Reform Act. Any significant variance of our current interpretation of such legislation from any future regulations or interpretive guidance could result in a change to the presentation of our financial condition and results of operations and could negatively affect our business. Certain U.S. federal income tax deductions currently available with respect to oil and natural gas exploration and production may be eliminated as a result of future legislation. The elimination of certain key U.S. federal income tax deductions currently available to oil and natural gas exploration and production companies may be proposed in the future. These changes may include, among other proposals: • • • • repeal of the percentage depletion allowance for natural gas and oil properties; elimination of current deductions for intangible drilling and development costs; elimination of the deduction for certain domestic production activities; and extension of the amortization period for certain geological and geophysical expenditures. SWN 54 FINAL GLOSSY v6 - 4000dpi Double.pdf 38 3/25/19 5:17 PM The passage of these or any similar changes in U.S. federal income tax laws to eliminate or postpone certain tax deductions that are currently available with respect to oil and natural gas exploration and development could have an adverse effect on our financial position, results of operations and cash flows. We may experience adverse or unforeseen tax consequences due to further developments affecting our deferred tax assets that could significantly affect our results. Deferred tax assets, including net operating loss carryforwards, represent future savings of taxes that would otherwise be paid in cash. At December 31, 2018, we had substantial amounts of net operating loss carryforwards for U.S. federal and state income tax purposes. Limitations may exist upon use of these carryforwards in the event that a change in control of the Company occurs. Additionally, due to the Tax Reform Act’s permanent reduction of the corporate income tax rate, we were required to write down our deferred tax assets (including our net operating loss carryforwards), and there may be other material adverse effects on our deferred tax assets resulting from the Tax Reform Act that we have not yet identified. A valuation allowance for deferred tax assets, including net operating losses, is recognized when it is more likely than not that some or all of the benefit from the deferred tax asset will not be realized. At December 31, 2018, we recorded a valuation allowance against our entire deferred tax asset, including the portion related to the remaining net operating loss carryforwards. This allowance was recorded primarily as a result of cumulative book losses experienced over the three-year period ending December 31, 2018. If we experience additional book losses, we may be required to increase our valuation allowance against our deferred tax assets. Our existing deferred tax asset valuation allowance may also be released if significant events occur or market conditions change materially, and our current or future earnings are, or are projected to be, significantly higher than we currently estimate. This release may result in a significant one-time favorable impact positively affecting our consolidated results of operations for the period of reversal and for the full fiscal year results. A cyber incident could result in information theft, data corruption, operational disruption and/or financial loss. Our business has become increasingly dependent on digital technologies to conduct day-to-day operations, including certain exploration, development and production activities as well as processing of revenues and payments. We depend on digital technology, including information systems and related infrastructure as well as cloud applications and services, to process and record financial and operating data, analyze seismic and drilling information, conduct reservoir modeling and reserves estimation, communicate with employees and business associates, perform compliance reporting and in many other activities related to our business. Our vendors, service providers, purchasers of our production, and financial institutions are also dependent on digital technology. As dependence on digital technologies has increased, cyber incidents, including deliberate attacks or unintentional events, have also increased. Our technologies, systems, networks, and those of our business associates may become the target of cyber-attacks or information security breaches, which could lead to disruptions in critical systems, unauthorized release of confidential or protected information, corruption of data or other disruptions of our business operations. In addition, certain cyber incidents, such as surveillance, may remain undetected for an extended period. A cyber-attack involving our information systems and related infrastructure, or that of companies with which we deal, could disrupt our business and negatively impact our operations in a variety of ways, including: • • • • • unauthorized access to seismic data, reserves information, strategic information or other sensitive or proprietary information could have a negative impact on our ability to compete for natural gas and oil resources; unauthorized access to personal identifying information of royalty owners, employees and vendors, which could expose us to allegations that we did not sufficiently protect that information; data corruption or operational disruption of production infrastructure could result in loss of production, or accidental discharge; a cyber-attack on a vendor or service provider could result in supply chain disruptions which could delay or halt our major development projects; and a cyber-attack on a third party gathering, pipeline or rail service provider could delay or prevent us from marketing our production, resulting in a loss of revenues. These events could damage our reputation and lead to financial losses from remedial actions, loss of business or potential liability, which could have a material adverse effect on our financial condition, results of operations or cash flows. SWN 55 FINAL GLOSSY v6 - 4000dpi Double.pdf 39 3/25/19 5:17 PM To date we have not experienced any material losses relating to cyber-attacks; however, there can be no assurance that we will not suffer such losses in the future. As cyber threats continue to evolve, we may be required to expend significant additional resources to continue to modify or enhance our protective measures or to investigate and remediate any information security vulnerabilities. Terrorist activities could materially and adversely affect our business and results of operations. Terrorist attacks and the threat of terrorist attacks, whether domestic or foreign attacks, as well as military or other actions taken in response to these acts, could cause instability in the global financial and energy markets. Continued hostilities in the Middle East and the occurrence or threat of terrorist attacks in the United States or other countries could adversely affect the global economy in unpredictable ways, including the disruption of energy supplies and markets, increased volatility in commodity prices or the possibility that the infrastructure on which we rely could be a direct target or an indirect casualty of an act of terrorism, and, in turn, could materially and adversely affect our business and results of operations. Negative public perception regarding us and/or our industry could have an adverse effect on our operations. Negative public perception regarding us and/or our industry resulting from, among other things, concerns raised by advocacy groups about emissions, hydraulic fracturing, seismicity, oil spills and explosions of transmission lines, may lead to regulatory scrutiny, which may, in turn, lead to new state and federal safety and environmental laws, regulations, guidelines and enforcement interpretations. These actions may cause operational delays or restrictions, increased operating costs, additional regulatory burdens and increased risk of litigation. Moreover, governmental authorities exercise considerable discretion in the timing and scope of permit issuance and the public may engage in the permitting process, including through intervention in the courts. Negative public perception could cause the permits we need to conduct our operations to be withheld, delayed, or burdened by requirements that restrict our ability to profitably conduct our business. Judicial decisions can affect our rights and obligations. Our ability to develop gas, oil and NGLs depends on the leases and other mineral rights we acquire and the rights of owners of nearby properties. We operate in areas where judicial decisions have not yet definitively interpreted various contractual provisions or addressed relevant aspects of property rights, nuisance and other matters that could be the source of claims against us as a developer or operator of properties. Although we plan our activities according to our expectations of these unresolved areas, based on decisions on similar issues in these jurisdictions and decisions from courts in other states that have addressed them, courts could resolve issues in ways that increase our liabilities or otherwise restrict or add costs to our operations. Common stockholders will be diluted if additional shares are issued. From time to time we have issued stock to raise capital for our business, including significant offerings of new shares in 2015 and 2016. We also issue restricted stock, options and performance share units to our employees and directors as part of their compensation. In addition, we may issue additional shares of common stock, additional notes or other securities or debt convertible into common stock, to extend maturities or fund capital expenditures. If we issue additional shares of our common stock in the future, it may have a dilutive effect on our current outstanding stockholders. Anti-takeover provisions in our organizational documents and under Delaware law may impede or discourage a takeover, which could cause the market price of our common stock to decline. We are a Delaware corporation, and the anti-takeover provisions of Delaware law impose various impediments to the ability of a third party to acquire control of us, even if a change in control would be beneficial to our existing stockholders, which, under certain circumstances, could reduce the market price of our common stock. In addition, protective provisions in our Amended and Restated Certificate of Incorporation and Amended and Restated Bylaws or the implementation by our Board of Directors of a stockholder rights plan that could deter a takeover.

SWN 59 FINAL GLOSSY v6 - 4000dpi Double.pdf 43 3/25/19 5:17 PM During 2018, we were required to file Form 23, “Annual Survey of Domestic Oil and Gas Reserves,” with the U.S. Department of Energy. The basis for reporting reserves on Form 23 is not comparable to the reserve data included in “Supplemental Oil and Gas Disclosures” in Item 8 of Part II of this Annual Report. The primary differences are that Form 23 reports gross reserves, including the royalty owners’ share, and includes reserves for only those properties of which we are the operator. Title to Properties We believe that we have satisfactory title to substantially all of our active properties in accordance with standards generally accepted in the oil and natural gas industry. Our properties are subject to customary royalty and overriding royalty interests, certain contracts relating to the exploration, development, operation and marketing of production from such properties, consents to assignment and preferential purchase rights, liens for current taxes, applicable laws and other burdens, encumbrances and irregularities in title, which we believe do not materially interfere with the use of or affect the value of such properties. Prior to acquiring undeveloped properties, we endeavor to perform a title investigation that is thorough but less vigorous than that we endeavor to conduct prior to drilling, which is consistent with standard practice in the oil and natural gas industry. Generally, before we commence drilling operations on properties that we operate, we conduct a title examination and perform curative work with respect to significant defects that we identify. We believe that we have performed title review with respect to substantially all of our active properties that we operate. ITEM 3. LEGAL PROCEEDINGS We are subject to litigation, claims and proceedings that arise in the ordinary course of business, such as for alleged breaches of contract, miscalculation of royalties and pollution, contamination or nuisance. We accrue for such items when a liability is both probable and the amount can be reasonably estimated. It is not possible at this time to estimate the amount of any additional loss, or range of loss that is reasonably possible, but based on the nature of the claims, management believes that current litigation, claims and proceedings, individually or in aggregate and after taking into account insurance, are not likely to have a material adverse impact on our financial position, results of operations or cash flows, for the period in which the effect of that outcome becomes reasonably estimable. Many of these matters are in early stages, so the allegations and the damage theories have not been fully developed, and are all subject to inherent uncertainties; therefore, management’s view may change in the future. If an unfavorable final outcome were to occur, there exists the possibility of a material impact on our financial position, results of operations or cash flows for the period in which the effect becomes reasonably estimable. We are also subject to laws and regulations relating to the protection of the environment. Environmental and cleanup related costs of a non-capital nature are accrued when it is both probable that a liability has been incurred and when the amount can be reasonably estimated. Management believes any future remediation or other compliance related costs will not have a material effect on our financial position or results of operations. See “Litigation” in Note 9 – “Commitments and Contingencies” to the consolidated financial statements included in this Annual Report for further details on our current legal proceedings. ITEM 4.

E&P. Our primary business is the exploration for and production of natural gas, oil and NGLs, with our ongoing operations focused on the development of unconventional natural gas reservoirs located in Pennsylvania and West Virginia. Our operations in northeast Pennsylvania, which we refer to as “Northeast Appalachia,” are primarily focused on the unconventional natural gas reservoir known as the Marcellus Shale. Our operations in West Virginia and southwest Pennsylvania, which we refer to as “Southwest Appalachia,” are focused on the Marcellus Shale, the Utica and the Upper Devonian unconventional natural gas and oil reservoirs. Collectively, our properties in Pennsylvania and West Virginia are herein referred to as the “Appalachian Basin.” We also have drilling rigs located in Pennsylvania and West Virginia, and we provide certain oilfield products and services, principally serving our E&P operations though vertical integration. On August 30, 2018, we entered into an agreement to sell 100% of the equity in certain of our subsidiaries that conducted our operations in Arkansas, which were primarily focused on an unconventional natural gas reservoir known as the Fayetteville Shale, for $1,865 million, subject to customary adjustments. In early December 2018, we completed the Fayetteville Shale sale, resulting in net proceeds of $1,650 million, following adjustments due primarily to the net cash flows from the economic effective date of July 1, 2018, to the closing date. Midstream. Our marketing activities capture opportunities that arise through the marketing and transportation of natural gas, oil, and NGLs produced in our E&P operations. In December 2018, we divested almost all of our gathering assets as part of the Fayetteville Shale sale. Changes in 2018. At the beginning of 2018, we announced our strategy to reposition the Company through portfolio optimization, balance sheet management and leveraging our technical, commercial and operational expertise to improve margins. We sharpened our focus on developing our high-value, liquids-rich Appalachian basin assets. We strengthened our balance sheet through asset monetization and debt reduction by entering into a new reserve-based credit facility and paying down outstanding debt, which improved our debt maturity profile while preserving financial and operational flexibility. We sold our Fayetteville Shale assets, further reducing our debt, repurchasing shares and earmarking proceeds for our 2019 and 2020 capital investment programs and other general corporate purposes. We made further technological advances in drilling precision and completion optimization that enhanced well productivity and economics, resulting in improved returns, and we focused on identifying and implementing opportunities to lower our overall cost structure. We added to our derivative portfolio, protecting approximately 479 Bcfe and 117 Bcfe of our forecasted 2019 and 2020 production, respectively, from price volatility through the use of commodity derivatives. FINAL GLOSSY v6 - 4000dpi Double.pdf 49 3/25/19 5:17 PM SWN 65 Recent Financial and Operating Results Significant operating and financial highlights for 2018 include: Total Company • Net income attributable to common stock of $535 million, or $0.93 per diluted share, down from a net income attributable to common stock of $816 million, or $1.63 per diluted share, in 2017. The decrease was primarily due to a loss on unsettled derivatives of $24 million in 2018 as compared to a gain of $451 million in 2017. Excluding the impact of unsettled derivatives, net income attributable to common stock was up $194 million, or 53%, compared to 2017. • Net cash provided by operating activities of $1,223 million was up 11% from $1,097 million in 2017. • Total capital invested of $1,248 million was down 3% from $1,293 million in 2017. • Total debt of approximately $2.3 billion decreased by $2.1 billion, or 47%, compared to 2017. • We repurchased approximately 39 million shares of our common stock for $180 million. E&P • E&P segment operating income of $794 million was up 45%, compared to $549 million in 2017. • Year-end reserves of 11,921 Bcfe decreased 19% from 14,775 Bcfe at the end of 2017. Excluding the 3,443 Bcfe of reserves sold during the year, year-end reserves were up 589 Bcfe, resulting from 946 Bcfe of production offset by 1,009 Bcfe of additions and 526 Bcfe of revisions. • Total net production of 946 Bcfe, including 702 Bcfe from our Appalachian Basin and 243 Bcf from the Fayetteville Shale, increased 5% from 2017, and was comprised of 85% natural gas and 15% oil and NGLs. • Excluding the effect of derivatives, our realized natural gas price of $2.45 per Mcf, realized oil price of $56.79 per barrel and realized NGL price of $17.91 per barrel increased 10%, 32% and 24%, respectively, from 2017. • The E&P segment invested $1,231 million in capital drilling 106 wells, completing 119 wells and placing 138 wells to sales. Outlook We expect to continue to exercise capital discipline through a fully-funded 2019 capital investment program. We remain committed to our focus on optimizing our portfolio by concentrating our efforts on our highest return assets, looking for opportunities to maximize margins in each core area of our business and further developing our knowledge of our asset base. We believe our industry will continue to face challenges due to the uncertainty of natural gas, oil and NGL prices in the United States, changes in laws, regulations and investor sentiment, and other key factors described above under “Risk Factors.” RESULTS OF OPERATIONS The following discussion of our results of operations for our segments is presented before intersegment eliminations. We evaluate our segments as if they were stand-alone operations and accordingly discuss their results prior to any intersegment eliminations. Restructuring charges, interest expense, gain (loss) on derivatives, loss on early extinguishment of debt and income tax expense are discussed on a consolidated basis.

(2) Approximately 240 Bcfe, 179 Bcfe and 148 Bcfe for the years ended December 31, 2018, 2017 and 2016, respectively, were produced from the Marcellus Shale formation. • Production volumes for our E&P segment increased by 49 Bcfe for the year ended December 31, 2018, compared to the same period in 2017, as increased production volumes from Northeast and Southwest Appalachia more than offset decreased natural gas production volumes in the Fayetteville Shale, which reflects only eleven months of production in 2018 as a result of its sale in December 2018. • E&P segment production volumes increased 22 Bcfe for the year ended December 31, 2017, compared to the same period in 2016, as increased natural gas production volumes in Northeast and Southwest Appalachia more than offset decreased production volumes in the Fayetteville Shale. Commodity Prices The price we expect to receive for our production is a critical factor in determining the capital investments we make to develop our properties. Commodity prices fluctuate due to a variety of factors we cannot control or predict, including increased supplies of natural gas, oil or NGLs due to greater exploration and development activities, weather conditions, political and economic events, and competition from other energy sources. These factors impact supply and demand, which in turn determine the sales prices for our production. In addition to these factors, the prices we realize for our production are affected by our hedging activities as well as locational differences in market prices, including basis differentials.

(6) Excludes $1 million of restructuring charges for the year ended December 31, 2018. (7) Excludes $3 million of restructuring charges for the year ended December 31, 2016. Lease Operating Expenses • On a per Mcfe basis, lease operating expenses increased $0.03 for the year ended December 31, 2018, compared to 2017, primarily due to additional NGL processing fees associated with our increased production in Southwest Appalachia. • Lease operating expenses per Mcfe increased $0.03 for the year ended December 31, 2017, compared to 2016, primarily due to increased transportation and processing costs, as our production growth shifted toward the Appalachian Basin. General and Administrative Expenses • General and administrative expenses decreased in 2018, compared to 2017, as a $20 million decrease in costs resulting from the mid-year implementation of cost reductions and decreased personnel costs was partially offset by a $4 million increase in legal settlement charges. • On a per Mcfe basis, excluding restructuring and legal settlement charges, general and administrative expenses per Mcfe decreased for the year ended December 31, 2018, compared to 2017, due to a 10% decrease in expenses and a 5% increase in production volumes. SWN 70 FINAL GLOSSY v6 - 4000dpi Double.pdf 54 3/25/19 5:17 PM • On a per Mcfe basis, excluding restructuring and legal settlement charges, general and administrative expenses per Mcfe remained flat for the year ended December 31, 2017, compared to 2016, as a slight increase in expenses was offset by a 3% increase in production volumes. Taxes, Other than Income Taxes • Taxes other than income taxes per Mcfe may vary from period to period due to changes in ad valorem and severance taxes that result from the mix of our production volumes and fluctuations in commodity prices. Excluding $1 million of restructuring charges in 2018, taxes, other than income taxes, per Mcfe decreased $0.01 per Mcfe for the year ended December 31, 2018, compared to the same period in 2017, primarily due to an $8 million severance tax refund related to a favorable assessment on deductible expenses in Southwest Appalachia, a $1 million severance tax refund related to a favorable assessment on deductible expenses in the Fayetteville Shale, favorable property tax assessments, and property and sales tax refunds recorded in the first quarter of 2018. • On a per Mcfe basis, taxes, other than income taxes, remained flat for the year ended December 31, 2017 compared to 2016 as a slight increase in expense was more than offset by an increase in production volumes. Full Cost Pool Amortization • Our full cost pool amortization rate increased $0.06 per Mcfe for the year ended December 31, 2018, as compared to 2017. The increase in the average amortization rate resulted primarily from the addition of future development costs associated with proved undeveloped reserves recognized as a result of improved commodity prices. • The amortization rate is impacted by the timing and amount of reserve additions and the costs associated with those additions, revisions of previous reserve estimates due to both price and well performance, write-downs that result from full cost ceiling impairments, proceeds from the sale of properties that reduce the full cost pool, and the levels of costs subject to amortization. We cannot predict our future full cost pool amortization rate with accuracy due to the variability of each of the factors discussed above, as well as other factors, including but not limited to the uncertainty of the amount of future reserve changes. • Unevaluated costs excluded from amortization were $1.8 billion at December 31, 2018, and 2017, compared to $2.1 billion at December 31, 2016. The unevaluated costs excluded from amortization slightly decreased, as compared to 2017, as the evaluation of previously unevaluated properties totaling $361 million in 2018 was only partially offset by the impact of $299 million of unevaluated capital invested during the same period. See “Supplemental Oil and Gas Disclosures” in Item 8 of Part II of this Annual Report for additional information regarding our unevaluated costs excluded from amortization. Impairments In accordance with accounting guidance for Property, Plant and Equipment, assets held for sale are measured at the lower of carrying value or fair value less costs to sell. Because the assets outside the full cost pool met the criteria for held for sale accounting in the third quarter of 2018, we determined the carrying value of certain non-full cost pool E&P assets exceeded the fair value less costs to sell. As a result, an impairment charge of $15 million was recorded during the year ended December 31, 2018.

The impairments were comprised of $145 million related to our gathering assets included in the Fayetteville Shale sale, and $10 million related to other non-core gathering assets. Excluding the impairment and restructuring charges, operating income from our Midstream segment decreased $22 million for the year ended December 31, 2018, compared to 2017, primarily due to an $83 million decrease in gas gathering revenues and a $1 million decrease in marketing margin, partially offset by a $33 million decrease in operating costs and expenses and a $29 million increase in gain on sale of assets, net. • Operating income decreased $26 million for the year ended December 31, 2017, compared to 2016, primarily due to a $47 million decrease in gas gathering revenues and a $3 million decrease in marketing margin, partially offset by an $18 million decrease in operating costs and expenses and a $6 million gain on the sale of certain compressor equipment. • The margin generated from marketing activities was $42 million, $43 million and $46 million for the years ended December 31, 2018, 2017 and 2016, respectively. Margins are driven primarily by volumes marketed and may fluctuate depending on the prices paid for commodities and the ultimate disposition of those commodities. Increases and decreases in marketing revenues due to changes in commodity prices and volumes marketed are largely offset by corresponding changes in marketing purchase expenses. We enter into derivative contracts from time to time with respect to our marketing activities to provide margin protection. For more information about our derivatives and risk management activities, we refer you to Item 7A of Part II of this Annual Report and Note 5 to the consolidated financial statements included in this Annual Report. Revenues • Revenues from our marketing activities increased $630 million for the year ended December 31, 2018, compared to 2017, primarily due to a 12% increase in the price received for volumes marketed and a 96 Bcfe increase in the volumes marketed. • For the year ended December 31, 2017, revenues from our marketing activities increased $676 million, compared to 2016, primarily due to a 30% increase in the price received for volumes marketed and a 5 Bcfe increase in the volumes marketed. • Gas gathering revenues decreased $83 million for the year ended December 31, 2018, compared to the year ended December 31, 2017, primarily due to decreased volumes gathered in the Fayetteville Shale along with only approximately eleven months of gathering activity in 2018 as we sold our Fayetteville Shale gathering operations in early December 2018. SWN 72 FINAL GLOSSY v6 - 4000dpi Double.pdf 56 3/25/19 5:17 PM • Gas gathering revenues decreased $47 million for the year ended December 31, 2017, compared to the year ended December 31, 2016, primarily due to decreasing volumes gathered in the Fayetteville Shale. Operating Costs and Expenses • Operating costs and expenses for the year ended December 31, 2018 included $2 million of restructuring charges. Excluding these charges, operating costs and expenses decreased $33 million for the year ended December 31, 2018 compared to the year ended December 31, 2017, primarily due to an $18 million decrease in depreciation, an $8 million decrease in general and administrative expenses, a $6 million decrease in gathering operating expenses and a $1 million decrease in taxes other than income taxes. In addition, the sale of our gathering assets in early December 2018 resulted in only approximately eleven months of gathering operations for 2018. • Operating costs and expenses for the year ended December 31, 2016 included $3 million of restructuring charges. Excluding this charge, operating costs and expenses decreased $15 million for the year ended December 31, 2017 compared to the year ended December 31, 2016, primarily due to reduced compression and personnel costs due to lower activity levels as a result of decreasing volumes gathered in the Fayetteville Shale. Impairments In the second quarter of 2018, we recorded an impairment charge of $10 million related to certain non-core gathering assets. In the third quarter of 2018, the Fayetteville Shale gathering assets were classified as held for sale. As such, we determined the carrying value of our gathering assets held for sale exceeded the fair value less the costs to sell. As a result, we recorded an impairment charge of $145 million in 2018. Consolidated Restructuring Charges On June 27, 2018, we announced a workforce reduction plan, which resulted primarily from our previously announced study of structural, process and organizational changes to enhance shareholder value and continues with respect to other aspects of our business and activities. Affected employees were offered a severance package, which included a one-time cash payment depending on length of service and, if applicable, the current value of a portion of equity awards that were cancelled. We recognized $23 million in restructuring charges related to the workforce reduction plan for the year ended December 31, 2018. In December 2018, we closed the sale of the equity in certain of our subsidiaries that owned and operated our Fayetteville Shale E&P and related midstream gathering assets in Arkansas. As part of this transaction, most employees associated with those assets became employees of the buyer although the employment of some was or will be terminated. All affected employees were offered a severance package, which included a one-time cash payment depending on length of service and, if applicable, the current value of a portion of equity awards that were forfeited. We incurred $12 million in severance costs related to the Fayetteville Shale sale for the year ended December 31, 2018 and have recognized these costs as restructuring charges. As a result of the Fayetteville Shale sale, we incurred $4 million in charges primarily related to office consolidation and have recognized these costs as restructuring charges. For the year ended December 31, 2018, we recognized total restructuring charges of $39 million, of which $33 million was related to cash severance, including payroll taxes withheld and professional fees. The plans had been substantially implemented as of the end of the year, however, certain employment terminations were delayed into 2019. As of December 31, 2018, we had recorded a liability of $5 million related to severance to be paid out in 2019. In January 2016, we announced a workforce reduction, which was substantially concluded by the end of March 2016. In April 2016, we also partially restructured executive management. Affected employees were offered a severance package that included a one-time cash payment depending on length of service and, if applicable, accelerated vesting of outstanding stock-based equity awards. As a result of the workforce reduction and executive management restructuring, we recognized restructuring charges of $73 million for the year ended December 31, 2016.

Interest expense related to our senior notes decreased for the year ended December 31, 2017, as compared to the same period in 2016, as a decrease in interest expense related to the gradual redemption of our 7.50% Senior Notes due in February 2018, which began in July 2016 and completed in May 2017, was only partially offset by increased interest expense which resulted from the issuance of new senior notes in September 2017. Interest expense related to our credit arrangements decreased for the year ended December 31, 2018, as compared to the same period in 2017, primarily due to the extinguishment of our 2016 term loan and entering into our revolving credit facility in April 2018, which decreased our outstanding borrowing amount, and the repayment of our revolving credit facility borrowings with a portion of the net proceeds from the Fayetteville Shale sale. For the year ended December 31, 2017, interest expense related to our credit arrangements increased, as compared to the same period in 2016, due to increased outstanding borrowings and higher interest rates. • Capitalized interest increased $2 million for the year ended December 31, 2018, compared to the same period in 2017, and increased as a percentage of gross interest expense due to our increased cost of borrowing. The decreases in capitalized interest for the year ended December 31, 2017, as compared to the same period in 2016, were primarily due to the continued evaluation of a portion of our Southwest Appalachia assets.

We refer you to Note 5 to the consolidated financial statements included in this Annual Report for additional details about our gain (loss) on derivatives. Loss on Early Extinguishment of Debt • In December 2018, we used a portion of the net proceeds from our Fayetteville Shale sale to repurchase $40 million of our senior notes due January 2020, $787 million of our senior notes due March 2022 and $73 million of our senior notes due January 2025. We recognized a loss of $9 million for the redemption of these senior notes, which included $2 million of premiums paid. SWN 74 FINAL GLOSSY v6 - 4000dpi Double.pdf 58 3/25/19 5:17 PM • Concurrent with the closing of our revolving credit facility on April 26, 2018, we repaid our $1,191 million 2016 secured term loan balance and recognized a loss on early debt extinguishment of $8 million on the consolidated statements of operations related to the unamortized debt issuance expense. • • In September 2017, we used the net proceeds of approximately $1.1 billion from our September 2017 senior notes offering to repurchase approximately $758 million of our 2020 Senior Notes and to repay the remaining $327 million principal amount outstanding of our 2015 Term Loan. We recognized a loss of $59 million for the redemption of these senior notes which included $53 million of premiums paid. In the first half of 2017, we redeemed the remaining $276 million principal amount outstanding of our 2018 Senior Notes, recognizing a loss of $11 million. • During the third quarter of 2016, we used proceeds from our $1,247 million July 2016 equity offering to purchase and retire $700 million of our outstanding senior notes due in the first quarter of 2018 and retire $375 million of our $750 million term loan entered into in November 2015. We recognized a loss of $51 million for the redemption of these senior notes, which included $50 million of premiums paid. Income Taxes (in millions except percentages) Income tax expense (benefit) Effective tax rate For the years ended December 31, 2017 2016 2018 $ 1 $ 0% (93) $ (10%) (29) 1% • The income tax expense recognized for the year ended December 31, 2018 increased, as compared with 2017, primarily due to state income taxes resulting from the Fayetteville Shale sale partially offset by a benefit recorded related to an increased alternative minimum tax receivable, as well as changes to the overall valuation allowance activity during 2018. • The income tax benefits recognized for the year ended December 31, 2017 primarily resulted from changes in federal tax legislation enacted under the Tax Cuts and Jobs Act (Tax Reform) which will allow us to recover certain alternative minimum tax credit carryovers, along with the expiration of a portion of our uncertain tax provision. • Our low effective tax rate is the result of our recognition of a valuation allowance that reduced the deferred tax asset primarily related to our current net operating loss carryforward, as well as changes to the deferred tax rate enacted under the recent Tax Reform. A valuation allowance for deferred tax assets, including net operating losses, is recognized when it is more likely than not that some or all of the benefit from the deferred tax asset will not be realized. We refer you to Note 10 to the consolidated financial statements included in this Annual Report for additional discussion about our income taxes. LIQUIDITY AND CAPITAL RESOURCES We depend on funds generated from our operations, our cash and cash equivalents balance, our revolving credit facility and capital markets as our primary sources of liquidity. Although we have financial flexibility with our cash balance and the ability to draw on our $2.0 billion revolving credit facility (less outstanding letters of credit which were approximately $0.1 billion as of December 31, 2018), we continue to be committed to our capital discipline strategy of investing within our cash flow from operations net of changes in working capital, supplemented by a portion of the net proceeds from the Fayetteville Shale sale. As discussed in Note 3 to the consolidated financial statements included in this Annual Report, in December 2018, we closed on the Fayetteville Shale sale and received net proceeds of approximately $1,650 million, which included preliminary purchase price adjustments of approximately $215 million primarily related to the net cash flows from the economic effective date to the closing date. From the net proceeds received, $914 million was used to repurchase $900 million of our outstanding senior notes along with related accrued interest and retirement premiums paid, as discussed in Note 8 to the consolidated financial statements included in this Annual Report, and through December 31, 2018, $180 million has been used to repurchase approximately 39 million shares of our outstanding common stock. We may use a portion of the remaining net proceeds from the Fayetteville Shale sale to supplement cash flow related to the further development of our liquids-rich Appalachian assets in order to accelerate the path to self-funding and for general corporate purposes. Pending these other uses, a portion of these remaining net proceeds have been used to repay revolving credit facility borrowings until investments are made. SWN 75 FINAL GLOSSY v6 - 4000dpi Double.pdf 59 3/25/19 5:17 PM Our cash flow from operating activities is highly dependent upon the sales prices that we receive for our natural gas and liquids production. Natural gas, oil and NGL prices are subject to wide fluctuations and are driven by market supply and demand, which is impacted by many factors. The sales price we receive for our production is also influenced by our commodity hedging activities. Our derivative contracts allow us to ensure a certain level of cash flow to fund our operations. See “Risk Factors” in Item 1A, “Quantitative and Qualitative Disclosures about Market Risk” in Item 7A and Note 5 to the consolidated financial statements included in this Annual Report for further details. Our commodity hedging activities are subject to the credit risk of our counterparties being financially unable to settle the transaction. We actively monitor the credit status of our counterparties, performing both quantitative and qualitative assessments based on their credit ratings and credit default swap rates where applicable, and to date have not had any credit defaults associated with our transactions. However, any future failures by one or more counterparties could negatively impact our cash flow from operating activities. Our short-term cash flows are also dependent on the timely collection of receivables from our customers and joint interest owners. We actively manage this risk through credit management activities and, through the date of this filing, have not experienced any significant write-offs for non-collectable amounts. However, any sustained inaccessibility of credit by our customers and joint interest partners could adversely impact our cash flows. Due to the above factors, we are unable to forecast with certainty our future level of cash flow from operations. Accordingly, we expect to adjust our discretionary uses of cash depending upon available cash flow. Further, we may from time to time seek to retire, rearrange or amend some or all of our outstanding debt or debt agreements through cash purchases, and/or exchanges, open market purchases, privately negotiated transactions, tender offers or otherwise. Such transactions, if any, will depend on prevailing market conditions, our liquidity requirements, contractual restrictions and other factors. The amounts involved may be material. Credit Arrangements and Financing Activities On April 26, 2018, as part of our strategic effort to increase financial flexibility and reduce costs, we replaced our credit facilities (which consisted of a $1,191 million secured term loan and two unsecured revolving credit facilities totaling $809 million) with a new revolving credit facility. The 2018 revolving credit facility initially had a maximum borrowing capacity of $3.5 billion and commitments of $2.0 billion and is subject to semiannual borrowing base redeterminations by the lenders in April and October. Borrowings also may not exceed the permitted lien limitations in our senior note indentures. The borrowing base is subject to change based primarily on drilling results, commodity prices, the level of capital investing and operating costs. In October 2018, our borrowing base was reduced from an initial $3.2 billion to $3.1 billion and, upon the closing of the Fayetteville Shale sale in December 2018, was reduced to $2.1 billion with our commitments remaining at $2.0 billion. The permitted lien provisions in the senior note indentures currently limit liens securing indebtedness to the greater of $2.0 billion and 25% of adjusted consolidated net tangible assets. The 2018 revolving credit facility matures in April 2023, and as of December 31, 2018, had no borrowings outstanding. We also have $112 million in letters of credit outstanding but not drawn with banks in our credit facility. By entering into the 2018 revolving credit facility, we realized certain benefits including: • Reduction in debt outstanding and simplification of our capital structure by consolidating the components of the 2016 credit facility into a senior secured revolving credit facility and by terminating our 2013 credit facility (consisting of an unsecured $66 million revolving credit facility). • Reduced interest expense due to both the termination of the $1,191 million secured term loan and lower interest margins associated with the 2018 revolving credit facility. • Greater access to liquidity by extending the maturity from December 2020 (under the 2016 credit facility) to April 2023 under the 2018 revolving credit facility. • Increased financial flexibility by eliminating certain provisions in the 2016 credit facility associated with minimum liquidity requirements and restrictions on asset sale proceeds. In the fourth quarter of 2018, we entered into hedges that, when added to then-existing hedges including hedges put in place as part of the Fayetteville Shale sale that the buyer was obligated to assume at closing of that sale, exceeded a cap on hedges for the month of December 2018 under a covenant under our credit agreement. In conjunction with the closing, the buyer paid for the settlement of the December 2018 hedges it was to assume. The lenders have subsequently waived all matters associated with this default. Otherwise, as of December 31, 2018, we were in compliance with all of the remaining covenants of our revolving credit facility in all material respects. Although we do not anticipate any future violations of the financial covenants, our ability to comply with these covenants is in part dependent upon the success of our exploration and SWN 76 FINAL GLOSSY v6 - 4000dpi Double.pdf 60 3/25/19 5:17 PM development program and upon factors beyond our control, such as the market prices for natural gas and liquids. We refer you to Note 8 to the consolidated financial statements included in this Annual Report for additional discussion of the covenant requirements of our revolving credit facility. The credit status of the financial institutions participating in our revolving credit facility could adversely impact our ability to borrow funds under the revolving credit facility. Although we believe all of the lenders under the facility have the ability to provide funds, we cannot predict whether each will be able to meet their obligation to us. We refer you to Note 8 to the consolidated financial statements included in this Annual Report for additional discussion of our revolving credit facility. In December 2018, we closed on the Fayetteville Shale sale resulting in net proceeds of approximately $1,650 million, following customary preliminary purchase price adjustments of $215 million primarily related to the net cash flows from the economic effective date to the closing date and certain other working capital adjustments. We used a portion of the net proceeds to repurchase $900 million of our outstanding senior notes. Because of the focused work on refinancing and repayment of our debt during 2017 and 2018, only $265 million, or 11%, of our outstanding debt balance as of December 31, 2018 will come due prior to 2025, with only $52 million of that coming due in the next three years. We expect to save approximately $80 million in annual debt interest from our 2018 debt reduction efforts. At February 26, 2019, we had a long-term issuer credit rating of Ba2 by Moody’s, a long-term debt rating of BB by S&P and a long-term issuer default rating of BB by Fitch Ratings. Any upgrades or downgrades in our public debt ratings by Moody’s or S&P could decrease or increase our cost of funds, respectively.

FINAL GLOSSY v6 - 4000dpi Double.pdf 61 3/25/19 5:17 PM SWN 77 Cash Flow from Investing Activities • Total E&P capital investing decreased $17 million for the year ended December 31, 2018, compared to the same period in 2017, due to an $11 million decrease in direct E&P capital investing and a $6 million decrease in capitalized interest and internal costs. Of the $1,231 million invested in our E&P segment for the year ended December 31, 2018, 95% was invested in the Appalachian Basin. • For the year ended December 31, 2017, total E&P capital investing increased $625 million, compared to the same period in 2016, due to a $652 million increase in direct E&P capital investing which was only partially offset by a $27 million decrease in capitalized interest and internal costs. The significant increase in 2017 capital investing resulted from our decision to suspend drilling activity in the first half of 2016 due to an unfavorable commodity price environment. We began increasing activity in the second half of 2016. • The increase in capitalized interest for the year ended December 31, 2018, as compared to the same period in 2016, was primarily due to the increase in cost of borrowing as we reduced our near-term debt which had lower interest rates. • The decrease in capitalized interest for the year ended December 31, 2017, as compared to the same period in 2016, was primarily due to the continued evaluation of a portion of our Southwest Appalachia assets acquired in December 2014. • Midstream capital investing decreased $23 million for the year ended December 31, 2018, compared to the same period in 2017, primarily due to the shift in focus to our core E&P assets. • For the year ended December 31, 2017, Midstream capital investing increased $11 million, compared to the same period in 2016, primarily due to the purchase of several leased compressors in 2017 which were subsequently sold to third parties for a net gain of $6 million.

(2) Debt, net of cash and cash equivalents is a non-GAAP financial measure of a company’s ability to repay its debt if it was all due today. • Net cash used in financing activities for the year ended December 31, 2018 was $2,297 million, compared to net cash used in financing activities of $352 million for the same period in 2017. • • • In January 2018, we paid $27 million for a preferred stock dividend declared in the fourth quarter of 2017. In April 2018, we fully repaid our $1,191 million 2016 term loan and replaced it with the 2018 revolving credit facility with a $2.1 billion borrowing base. We recognized a loss on early extinguishment of debt of $8 million. In December 2018, upon closing of the Fayetteville Shale sale, a portion of the sale proceeds was used to complete a tender offer to repurchase $40 million of our 4.05% Senior Notes due January 2020, $787 million of our 4.10% Senior Notes due March 2022 and $73 million of our 4.95% Senior Notes due January 2025, reducing annual bond debt interest by approximately $39 million. We recognized a loss on early extinguishment of debt of $9 million, primarily related to the early retirement premiums. • We also used a portion of the net proceeds from the Fayetteville Shale sale to repurchase 39 million shares of common stock for approximately $180 million. We refer you to Note 8 to the consolidated financial statements included in this Annual Report for additional discussion of our outstanding debt and credit facilities. Working Capital • We had positive working capital of $110 million at December 31, 2018 primarily due to $201 million of cash and cash equivalents resulting from the net proceeds from the Fayetteville Shale sale and an increase in accounts receivable primarily related to the increase in commodity pricing in December 2018, as compared to December 2017. • At December 31, 2017, we had positive working capital of $729 million primarily due to $916 million of cash and cash equivalents resulting from our fully-drawn 2016 term loan. Off-Balance Sheet Arrangements We may enter into off-balance sheet arrangements and transactions that can give rise to material off-balance sheet obligations. As of December 31, 2018, our material off-balance sheet arrangements and transactions include operating lease arrangements, $112 million in letters of credit outstanding against our 2018 revolving credit facility and $55 million in surety SWN 79 FINAL GLOSSY v6 - 4000dpi Double.pdf 63 3/25/19 5:17 PM bonds issued as financial assurance on certain agreements. There are no other transactions, arrangements or other relationships with unconsolidated entities or other persons that are reasonably likely to materially affect our liquidity or availability of our capital resources. For more information regarding off-balance sheet arrangements, we refer you to “Contractual Obligations and Contingent Liabilities and Commitments” below for more information on our operating leases. Contractual Obligations and Contingent Liabilities and Commitments We have various contractual obligations in the normal course of our operations and financing activities. Significant contractual obligations as of December 31, 2018, were as follows: Contractual Obligations (in millions) Transportation charges (1) Debt Interest on debt (2) Operating leases (3) Compression services (4) Operating agreements Purchase obligations Other obligations (5) Payments Due by Period Total Less than 1 Year 1 to 3 Years 3 to 5 Years 5 to 8 Years More than 8 Years $ $ 8,794 $ 2,342 1,161 94 5 42 52 20 12,510 $ 773 $ – 165 38 3 39 52 12 1,082 $ 1,408 $ 52 327 41 2 2 – 8 1,840 $ 1,268 $ 213 306 11 – 1 – – 1,799 $ 1,744 $ 1,577 324 3 – – – – 3,648 $ 3,601 500 39 1 – – – – 4,141 (1) As of December 31, 2018, we had commitments for demand and similar charges under firm transportation and gathering agreements to guarantee access capacity on natural gas and liquids pipelines and gathering systems. Of the total $8.8 billion, $3.1 billion related to access capacity on future pipeline and gathering infrastructure projects that still require the granting of regulatory approvals and additional construction efforts. For further information, we refer you to “Operational Commitments and Contingencies” in Note 9 to the consolidated financial statements included in this Annual Report. This amount also included guarantee obligations of up to $463 million. Included in the transportation charges above are $114 million (potentially due in less than one year) and $107 million (potentially due in one to two years) related to certain agreements that remain in the name of our marketing affiliate but are expected to be paid in full by Flywheel Energy Operating, LLC, the purchaser of the Fayetteville Shale assets. Of these amounts, we may be obligated to reimburse Flywheel Energy for a portion of volumetric shortfalls during 2019 and 2020 (up to $102 million) under these transportation agreements and have currently recorded an $88 million liability as of December 31, 2018. Subsequent to December 31, 2018, we agreed to purchase firm transportation with pipelines in the Appalachian Basin starting in 2021 and running through 2032 totaling $357 million in total contractual commitments of which the seller has agreed to reimburse us for $133 million of this commitment. (2) Interest payments on our senior notes were calculated utilizing the fixed rates associated with our fixed rate notes outstanding at December 31, 2018. Estimated interest payments on the revolving credit facility were excluded from this table since there was no outstanding balance at December 31, 2018 on our revolving credit facility. Senior note interest rates were based on our credit ratings as of December 31, 2018. (3) Operating leases include costs for compressors, drilling rigs, pressure pumping equipment, aircraft, office space and other equipment under non- cancelable operating leases expiring through 2028. (4) As of December 31, 2018, our E&P segment had commitments of approximately $4.9 million for compression services associated primarily with our Southwest Appalachia division. (5) Our other significant contractual obligations include approximately $16 million for various information technology support and data subscription agreements. Liabilities relating to uncertain tax positions are excluded from the table above as there is a high degree of uncertainty regarding the timing of future cash outflows related to such liabilities. Also excluded from the table above are future contributions to the pension and postretirement benefit plans. For further information regarding our pension and other postretirement benefit plans, we refer you to Note 12 to the consolidated financial statements included in this Annual Report and “Critical Accounting Policies and Estimates” below for additional information. We refer you to Note 8 to the consolidated financial statements included in this Annual Report for a discussion of the terms of our debt. We are subject to various litigation, claims and proceedings that arise in the ordinary course of business, such as for alleged breaches of contract, miscalculation of royalties, employment matters, traffic incidents, pollution, contamination, encroachment on others’ property or nuisance. We accrue for such items when a liability is both probable and the amount can be reasonably estimated. It is not possible at this time to estimate the amount of any additional loss, or range of loss that is reasonably possible, but based on the nature of the claims, management believes that current litigation, claims and proceedings, individually or in aggregate and after taking into account insurance, are not likely to have a material adverse SWN 80 FINAL GLOSSY v6 - 4000dpi Double.pdf 64 3/25/19 5:17 PM impact on our financial position, results of operations or cash flows, although it is possible that adverse outcomes could have a material adverse effect on our results of operations or cash flows for the period in which the effect of that outcome becomes reasonably estimable. Many of these matters are in early stages, so the allegations and the damage theories have not been fully developed, and are all subject to inherent uncertainties; therefore, management’s view may change in the future. We are also subject to laws and regulations relating to the protection of the environment. Environmental and cleanup related costs of a non-capital nature are accrued when it is both probable that a liability has been incurred and when the amount can be reasonably estimated. Management believes any future remediation or other compliance related costs will not have a material effect on our financial position, results of operations or cash flows. For further information, we refer you to “Litigation” and “Environmental Risk” in Note 9 to the consolidated financial statements included in this Annual Report. CRITICAL ACCOUNTING POLICIES AND ESTIMATES The discussion and analysis of financial condition and results of operations are based upon our consolidated financial statements, which have been prepared in accordance with accounting principles generally accepted in the United States. The preparation of these financial statements requires management to make estimates and judgments that affect the amounts of assets, liabilities, revenues and expenses and related disclosure of contingent assets and liabilities. We evaluate our estimates on an on-going basis, based on historical experience and on various other assumptions that are believed to be reasonable under the circumstances. Actual results may differ from these estimates under different assumptions or conditions. We believe the following describes significant judgments and estimates used in the preparation of our consolidated financial statements. Natural Gas and Oil Properties We utilize the full cost method of accounting for costs related to the exploration, development and acquisition of natural gas and oil properties. Under this method, all such costs (productive and nonproductive), including salaries, benefits and other internal costs directly attributable to these activities are capitalized on a country-by-country basis and amortized over the estimated lives of the properties using the units-of-production method. These capitalized costs are subject to a ceiling test that limits such pooled costs, net of applicable deferred taxes, to the aggregate of the present value of future net revenues attributable to proved natural gas, oil and NGL reserves discounted at 10% (standardized measure) plus the lower of cost or market value of unproved properties. Any costs in excess of the ceiling are written off as a non-cash expense. The expense may not be reversed in future periods, even though higher natural gas, oil and NGL prices may subsequently increase the ceiling. Companies using the full cost method are required to use the average quoted price from the first day of each month from the previous 12 months, including the impact of derivatives qualifying as cash flow hedges, to calculate the ceiling value of their reserves. Costs associated with unevaluated properties are excluded from our amortization base until we have evaluated the properties or impairment is indicated. The costs associated with unevaluated leasehold acreage and related seismic data, wells currently drilling and related capitalized interest are initially excluded from our amortization base. Leasehold costs are either transferred to our amortization base with the costs of drilling a well on the lease or are assessed at least annually for possible impairment or reduction in value. Our decision to withhold costs from amortization and the timing of the transfer of those costs into the amortization base involves a significant amount of judgment and may be subject to changes over time based on several factors, including our drilling plans, availability of capital, project economics and drilling results from adjacent acreage. At December 31, 2018, we had a total of $1,755 million of costs excluded from our amortization base, all of which related to our properties in the United States. Inclusion of some or all of these costs in our properties in the United States in the future, without adding any associated reserves, could result in ceiling test impairments. At December 31, 2018, the ceiling value of our reserves was calculated based upon the average quoted price from the first day of each month from the previous 12 months for Henry Hub natural gas of $3.10 per MMBtu, for West Texas Intermediate oil of $65.56 per barrel and NGLs of $17.64 per barrel, adjusted for market differentials. The net book value of our natural gas and oil properties did not exceed the ceiling amount and did not result in a ceiling test impairment at December 31, 2018. We had no derivative positions that were designated for hedge accounting as of December 31, 2018. Although no ceiling test impairment was recorded in 2018, future decreases in commodity prices, increases in costs and/or changes in the balance of costs excluded from amortization and other factors may result in impairments to our natural gas and oil properties. Using the average quoted price from the first day of each month from the previous 12 months for Henry Hub natural gas of $2.98 per MMBtu, West Texas Intermediate oil of $47.79 per barrel and NGLs of $14.41 per barrel, adjusted for market SWN 81 FINAL GLOSSY v6 - 4000dpi Double.pdf 65 3/25/19 5:17 PM differentials, the net book value of our United States natural gas and oil properties did not exceed the ceiling amount and did not result in a ceiling test impairment at December 31, 2017. We had no derivative positions that were designated for hedge accounting as of December 31, 2017. The net book value of our United States and Canada natural gas and oil properties exceeded the ceiling by approximately $641 million (net of tax) at March 31, 2016, $297 million (net of tax) at June 30, 2016 and $506 million (net of tax) at September 30, 2016 and resulted in non-cash ceiling test impairments in each of those quarters ended those dates. We had no hedge positions that were designated for hedge accounting as of March 31, 2016, June 30, 2016 and September 30, 2016. Using the average quoted price from the first day of each month from the previous 12 months for Henry Hub natural gas of $2.48 per MMBtu, West Texas Intermediate oil of $39.25 per barrel and NGLs of $6.74 per barrel, adjusted for market differentials, the net book value of our United States natural gas and oil properties did not exceed the ceiling amount and did not result in a ceiling test impairment at December 31, 2016. We had no derivative positions that were designated for hedge accounting as of December 31, 2016. A decline in natural gas, oil and NGL prices used to calculate the discounted future net revenues of our reserves affects both the present value of cash flows and the quantity of reserves. In the past, nearly all of our reserve base was natural gas; therefore changes in oil and NGL prices used did not have as significant an impact as natural gas prices on cash flows and reserve quantities. With the sale of our Fayetteville Shale assets, our reserve base as of December 31, 2018, however, was approximately 68% natural gas, 29% NGLs and 3% oil. Therefore NGL and oil pricing will have a more significant impact on the cash flows and quantity of reserves going forward. Our standardized measure and reserve quantities as of December 31, 2018, were $6.0 billion and 11.9 Tcfe, respectively. Natural gas, oil and NGL reserves cannot be measured exactly. Our estimate of natural gas, oil and NGL reserves requires extensive judgments of reservoir engineering data and projections of costs that will be incurred in developing and producing reserves and is generally less precise than other estimates made in connection with financial disclosures. Our reservoir engineers prepare our reserve estimates under the supervision of our management. Reserve estimates are prepared for each of our properties annually by the reservoir engineers assigned to the asset management team to which the property is assigned. The reservoir engineering and financial data included in these estimates are reviewed by senior engineers, who are not part of the asset management teams, and by our Director of Reserves, who is the technical person primarily responsible for overseeing the preparation of our reserves estimates. Our Director of Reserves has more than 24 years of experience in petroleum engineering, including the estimation of natural gas and oil reserves, and holds a Bachelor of Science in Petroleum Engineering. Prior to joining us in 2018, our Director of Reserves served in various reservoir engineering roles for EP Energy Company, El Paso Corporation, Cabot Oil & Gas Corporation, Schlumberger and H.J. Gruy & Associates, and is a member of the Society of Petroleum Engineers. He reports to our Executive Vice President and Chief Operations Officer, who has more than 30 years of experience in petroleum engineering including the estimation of natural gas, oil and NGL reserves in multiple basins in the United States, and holds a Bachelor of Science in Petroleum Engineering. Prior to joining Southwestern in 2017, our Chief Operations Officer served in various engineering and leadership roles for EP Energy Corporation, El Paso Corporation, ARCO Oil and Gas Company, Burlington Resources and Peoples Energy Production, and is a member of the Society of Petroleum Engineers. We engage NSAI, a worldwide leader of petroleum property analysis for industry and financial organizations and government agencies, to independently audit our proved reserves estimates as discussed in more detail below. NSAI was founded in 1961 and performs consulting petroleum engineering services under Texas Board of Professional Engineers Registration No. F-002699. Within NSAI, the two technical persons primarily responsible for auditing our proved reserves estimates (1) have over 37 years and over 16 years of practical experience in petroleum geosciences and petroleum engineering, respectively; (2) have over 27 years and over 16 years of experience in the estimation and evaluation of reserves, respectively; (3) each has a college degree; (4) each is a Licensed Professional Geoscientist in the State of Texas or a Licensed Professional Engineer in the State of Texas; (5) each meets or exceeds the education, training, and experience requirements set forth in the Standards Pertaining to the Estimating and Auditing of Oil and Gas Reserves Information promulgated by the Society of Petroleum Engineers; and (6) each is proficient in judiciously applying industry standard practices to engineering and geoscience evaluations as well as applying SEC and other industry reserves definitions and guidelines. The financial data included in the reserve estimates is also separately reviewed by our accounting staff. Our proved reserves estimates, as internally reviewed and audited by NSAI, are submitted for review and approval to our Chief Executive Officer. Finally, upon his approval, NSAI reports the results of its reserve audit to the Board of Directors, with whom final authority over the estimates of our proved reserves rests. A copy of NSAI’s report has been filed as Exhibit 99.1 to this Annual Report. Proved developed reserves generally have a higher degree of accuracy in this estimation process, when compared to proved undeveloped and proved non-producing reserves, as production history and pressure data over time is available for the majority of our proved developed properties. Proved developed reserves accounted for 47% of our total reserve base as of December 31, 2018. Assigning monetary values to such estimates does not reduce the subjectivity and changing nature of SWN 82 FINAL GLOSSY v6 - 4000dpi Double.pdf 66 3/25/19 5:17 PM such reserve estimates. The uncertainties inherent in the reserve estimates are compounded by applying additional estimates of the rates and timing of production and the costs that will be incurred in developing and producing the reserves. We cannot assure you that our internal controls sufficiently address the numerous uncertainties and risks that are inherent in estimating quantities of natural gas, oil and NGL reserves and projecting future rates of production and timing of development expenditures as many factors are beyond our control. We refer you to “Our proved natural gas, oil and NGL reserves are estimates that include uncertainties. Any material change to these uncertainties or underlying assumptions could cause the quantities and net present value of our reserves to be overstated or understated” in Item 1A, “Risk Factors,” of Part I of this Annual Report for a more detailed discussion of these uncertainties, risks and other factors. In conducting its audit, the engineers and geologists of NSAI study our major properties in detail and independently develop reserve estimates. NSAI’s audit consists primarily of substantive testing, which includes a detailed review of major properties that account for approximately 99% of the present worth of the company’s total proved reserves. NSAI’s audit process consists of sorting all fields by descending present value order and selecting the fields from highest value to descending value until the selected fields account for more than 80% of the present worth of our reserves. The fields included in approximately the top 99% present value as of December 31, 2018, accounted for approximately 99% of our total proved reserves and approximately 100% of our proved undeveloped reserves. In the conduct of its audit, NSAI did not independently verify the data we provided to them with respect to ownership interests, natural gas, oil and NGL production, well test data, historical costs of operation and development, product prices, or any agreements relating to current and future operations of the properties and sales of production. NSAI has advised us that if, in the course of its audit, something came to its attention that brought into question the validity or sufficiency of any such information or data, NSAI did not rely on such information or data until it had satisfactorily resolved any questions relating thereto or had independently verified such information or data. On January 16, 2019, NSAI issued its audit opinion as to the reasonableness of our reserve estimates for the year-ended December 31, 2018 stating that our estimated proved natural gas, oil and NGL reserves are, in the aggregate, reasonable and have been prepared in accordance with Standards Pertaining to the Estimating and Auditing of Oil and Gas Reserves Information promulgated by the Society of Petroleum Engineers. Assets and liabilities held for sale are subject to an assessment of fair value which includes many key valuation estimates, inputs and assumptions including but not limited to: production forecasts, pricing, basis differentials, operating and general and administrative expense forecasts, future development costs, discount rate determination and tax inputs. In the third quarter of 2018, we recognized certain assets and liabilities as held for sale related to the Fayetteville Shale sale requiring a comparison of their respective carrying cost and fair value less costs to sell. Our full cost pool assets were excluded from held for sale accounting treatment as they are governed by SEC Regulation S-X Rule 4-10. The fair value of our gathering assets to be sold was estimated using an estimated discounted cash flow model along with market assumptions. The assumptions used in the calculation of estimated discounted cash flows included future commodity prices, projections of estimated quantities of natural gas reserves, operating costs, projections of future rates of production, inflation factors and risk-adjusted discount rates. We believe the assumptions used were reasonable. Under full cost accounting rules, sales of oil and gas properties, whether or not being amortized currently, shall be accounted for as a reduction of the full cost pool, with no gain or loss recognized, unless such adjustments would significantly alter the relationship between capitalized costs and proved reserves of oil and gas attributable to a cost center. For instance, a significant alteration would not ordinarily be expected to occur for sales involving less than 25 percent of the reserve quantities of a given cost center. Judgments are required around the determination of whether a divestment is deemed significant. Such judgments include an assessment of the of the reserve quantities sold as compared to total reserve quantities and other qualitative and quantitative assessments of the relationship between capitalized costs and proved reserves. We did not recognize a gain or loss on the sale of our oil and gas properties as the divestment was deemed not significant. Please refer to Note 3 – “Divestitures” to the consolidated financial statements included in this Annual Report for further detail. Derivatives and Risk Management We use fixed price swap agreements and options to reduce the volatility of earnings and cash flow due to fluctuations in the prices of certain commodities and interest rates. Our policies prohibit speculation with derivatives and limit agreements to counterparties with appropriate credit standings to minimize the risk of uncollectability. We actively monitor the credit status of our counterparties based on their credit ratings and credit default swap rates where applicable, and to date have not had any credit defaults associated with our transactions. In 2018, 2017 and 2016 we financially protected 77%, 70% and 28% of our natural gas production, respectively, with derivatives. The primary risks related to our derivative contracts are the volatility in market prices and basis differentials for our production. However, the market price risk is generally offset by the gain or loss recognized upon the related transaction that is financially protected. All derivatives are recognized in the balance sheet as either an asset or a liability as measured at fair value other than transactions for which the normal purchase/normal sale exception is applied. Certain criteria must be satisfied for derivative SWN 83 FINAL GLOSSY v6 - 4000dpi Double.pdf 67 3/25/19 5:17 PM financial instruments to be designated for hedge accounting. Accounting guidance for qualifying hedges allows an unsettled derivative’s unrealized gains and losses to be recorded in either earnings or as a component of other comprehensive income until settled. In the period of settlement, we recognize the gains and losses from these qualifying hedges in gas sales revenues. The ineffective portion of those fixed price swaps was recognized in earnings. Gains and losses on derivatives that are not designated for hedge accounting treatment, or that do not meet hedge accounting requirements, are recorded as a component of gain (loss) on derivatives on the consolidated statements of operations. Accordingly, the gain (loss) on derivatives component of the statement of operations reflects the gains and losses on both settled and unsettled derivatives. We calculate gains and losses on settled derivatives as the summation of gains and losses on positions which have settled within the reporting period. As of December 31, 2018, none of our derivative contracts were designated for hedge accounting treatment. Changes in the fair value of unsettled derivatives that were not designated for hedge accounting treatment are recorded in gain (loss) on derivatives. See Note 5 to the consolidated financial statements included in this Annual Report for more information on our derivative position at December 31, 2018. Future market price volatility could create significant changes to the derivative positions recorded in our consolidated financial statements. We refer you to “Quantitative and Qualitative Disclosures about Market Risk” in Item 7A of Part II of this Annual Report for additional information regarding our hedging activities. Pension and Other Postretirement Benefits We record our prepaid or accrued benefit cost, as well as our periodic benefit cost, for our pension and other postretirement benefit plans using measurement assumptions that we consider reasonable at the time of calculation (see Note 12 to the consolidated financial statements included in this Annual Report for further discussion and disclosures regarding these benefit plans). Two of the assumptions that affect the amounts recorded are the discount rate, which estimates the rate at which benefits could be effectively settled, and the expected return on plan assets, which reflects the average rate of earnings expected on the funds invested. For the December 31, 2018 benefit obligation and periodic benefit cost to be recorded in 2019, the discount rate assumed is 4.35%. This compares to a discount rate of 3.75% and 4.20% for the benefit obligation and periodic benefit cost, respectively, recorded in 2018. For the 2019 periodic benefit cost, the expected return assumed remains 7.00%, from 2018. Using the assumed rates discussed above, we recorded total benefit cost of $9 million in 2018 related to our pension and other postretirement benefit plans. Due to the significance of the discount rate and expected long-term rate of return, the following sensitivity analysis demonstrates the effect that a 0.5% change in those assumptions would have had on our 2018 pension expense: (in millions) Discount rate Expected long-term rate of return Increase (Decrease) of Annual Pension Expense 0.5% Increase 0.5% Decrease $ $ (1) (1) $ $ 1 1 As of December 31, 2018, we recognized a liability of $47 million, compared to $59 million at December 31, 2017, related to our pension and other postretirement benefit plans. During 2018, we also made cash payments totaling $13 million to fund our pension and other postretirement benefit plans. Asset Retirement Obligations We must plug and abandon our wells when they no longer are producing. An asset retirement obligation associated with the retirement of a tangible long-lived asset is recognized as a liability in the period incurred or when it becomes determinable, with an associated increase in the carrying amount of the related long-lived asset. The cost of the tangible asset, including the asset retirement cost, is depreciated over the useful life of the asset. The asset retirement obligation is recorded at its estimated fair value and accretion expense is recognized over time as the discounted liability is accreted to its expected settlement value. The recognition of asset retirement obligations requires management to make assumptions that include estimated plugging and abandonment costs, timing of settlements, inflation rates and discount rates, all of which are subject to change. Stock-Based Compensation We account for stock-based compensation transactions using a fair value method and recognize an amount equal to the fair value of the stock options and stock-based payment cost in either the consolidated statement of operations or capitalize SWN 84 FINAL GLOSSY v6 - 4000dpi Double.pdf 68 3/25/19 5:17 PM the cost into natural gas and oil properties or gathering systems included in property and equipment. Costs are capitalized when they are directly related to the acquisition, exploration and development activities of our natural gas and oil properties or directly related to the construction of our gathering systems. We use models to determine fair value of stock-based compensation, which requires significant judgment with respect to forfeitures, volatility and other factors. Our stock-based compensation is classified as either an equity award or a liability award in accordance with generally accepted accounting principles. The fair value of an equity-classified award is determined at the grant date and is amortized on a straight-line basis over the vesting life of the award. The fair-value of a liability-classified award is determined on a quarterly basis through the final vesting date and is amortized based on the current fair value of the award and the percentage of vesting period incurred to date. New Accounting Standards Refer to Note 1 to the consolidated financial statements included in this Annual Report for further discussion of our significant accounting policies and for discussion of accounting standards that have been implemented in this report, along with a discussion of relevant accounting standards that are pending adoption.

We specifically disclaim all responsibility to publicly update any information contained in a forward-looking statement or any forward-looking statement in its entirety and therefore disclaim any resulting liability for potentially related damages. All forward-looking statements attributable to us are expressly qualified in their entirety by this cautionary statement. ITEM 7A. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK Market risks relating to our operations result primarily from the volatility in commodity prices, basis differentials and interest rates, as well as service costs and credit risk concentrations. We use fixed price swap agreements, options, basis swaps and interest rate swaps to reduce the volatility of earnings and cash flow due to fluctuations in the prices of natural gas, oil and certain NGLs along with interest rates. Our Board of Directors has approved risk management policies and procedures that utilize financial products for the reduction of defined commodity price risk. Utilization of financial products for the reduction of interest rate risks is also overseen by our Board of Directors. These policies prohibit speculation with derivatives and limit swap agreements to counterparties with appropriate credit standings. Credit Risk Our exposure to concentrations of credit risk consists primarily of trade receivables and derivative contracts associated with commodities trading. Concentrations of credit risk with respect to receivables are limited due to the large number of our purchasers and their dispersion across geographic areas. However, for the years ended December 31, 2018 and 2017, two subsidiaries of Royal Dutch Shell Plc in aggregate accounted for approximately 10.4% and 10.3%, respectively, of total natural gas, oil and NGL sales. A default on this account could have a material impact on the Company, but we do not believe that there is a material risk of an event of default. During the year ended December 31, 2016, no single third-party purchaser accounted for 10% or more of our consolidated revenues. We believe that the loss of any one customer would not have an adverse effect on our ability to sell our natural gas, oil and NGL production. See “Commodities Risk” below for discussion of credit risk associated with commodities trading. Interest Rate Risk As of December 31, 2018, we had approximately $2.3 billion of outstanding senior notes with a weighted average interest rate of 6.68%, and no borrowings under our revolving credit facility. We currently have an interest rate swap in effect to mitigate a portion of our exposure to volatility in interest rates. At December 31, 2018, we had a long-term issuer credit rating of Ba2 by Moody’s, a long-term debt rating of BB by S&P and a long-term debt issuer default rating of BB by Fitch Ratings. Any upgrades or downgrades in our public debt ratings by Moody’s or S&P could decrease or increase our cost of funds, respectively.

SWN 86 FINAL GLOSSY v6 - 4000dpi Double.pdf 70 3/25/19 5:17 PM Commodities Risk We use over-the-counter fixed price swap agreements and options to protect sales of our production against the inherent risks of adverse price fluctuations or locational pricing differences between a published index and the NYMEX futures market. These swaps and options include transactions in which one party will pay a fixed price (or variable price) for a notional quantity in exchange for receiving a variable price (or fixed price) based on a published index (referred to as price swaps) and transactions in which parties agree to pay a price based on two different indices (referred to as basis swaps). The primary market risks relating to our derivative contracts are the volatility in market prices and basis differentials for our production. However, the market price risk is offset by the gain or loss recognized upon the related sale or purchase of the production that is financially protected. Credit risk relates to the risk of loss as a result of non-performance by our counterparties. The counterparties are primarily major banks and integrated energy companies that management believes present minimal credit risks. The credit quality of each counterparty and the level of financial exposure we have to each counterparty are closely monitored to limit our credit risk exposure. Additionally, we perform both quantitative and qualitative assessments of these counterparties based on their credit ratings and credit default swap rates where applicable. We have not incurred any counterparty losses related to non-performance and do not anticipate any losses given the information we have currently. However, we cannot be certain that we will not experience such losses in the future. We refer you to Note 5 of the consolidated financial statements included in this Annual Report for additional details about our derivative instruments.

Management has assessed the effectiveness of the Company’s internal control over financial reporting as of December 31, 2018, utilizing the Committee of Sponsoring Organizations of the Treadway Commission’s Internal Control – Integrated Framework (2013). Based on this evaluation, management has concluded the Company’s internal control over financial reporting was effective as of December 31, 2018. The effectiveness of our internal control over financial reporting as of December 31, 2018 has been audited by PricewaterhouseCoopers LLP, an independent registered public accounting firm, as stated in its report which appears herein. Report of Independent Registered Public Accounting Firm To the Board of Directors and Stockholders of Southwestern Energy Company Opinions on the Financial Statements and Internal Control over Financial Reporting We have audited the accompanying consolidated balance sheets of Southwestern Energy Company and its subsidiaries (the “Company”) as of December 31, 2018 and 2017, and the related consolidated statements of operations, comprehensive income (loss), changes in equity and cash flows for each of the three years in the period ended December 31, 2018, including the related notes (collectively referred to as the “consolidated financial statements”). We also have audited the Company's internal control over financial reporting as of December 31, 2018, based on criteria established in Internal Control – Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO). In our opinion, the consolidated financial statements referred to above present fairly, in all material respects, the financial position of the Company as of December 31, 2018 and 2017, and the results of its operations and its cash flows for each of the three years in the period ended December 31, 2018 in conformity with accounting principles generally accepted in the United States of America. Also in our opinion, the Company maintained, in all material respects, effective internal control over financial reporting as of December 31, 2018, based on criteria established in Internal Control – Integrated Framework (2013) issued by the COSO. Basis for Opinions The Company’s management is responsible for these consolidated financial statements, for maintaining effective internal control over financial reporting, and for its assessment of the effectiveness of internal control over financial reporting, included in the accompanying Management's Report on Internal Control over Financial Reporting. Our responsibility is to express opinions on the Company’s consolidated financial statements and on the Company’s internal control over financial reporting based on our audits. We are a public accounting firm registered with the Public Company Accounting Oversight Board (United States) (PCAOB) and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB. We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audits to obtain reasonable assurance about whether the consolidated financial statements are free of material misstatement, whether due to error or fraud, and whether effective internal control over financial reporting was maintained in all material respects. Our audits of the consolidated financial statements included performing procedures to assess the risks of material misstatement of the consolidated financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the consolidated financial statements. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the consolidated financial statements. Our audit of internal control over financial reporting included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, and testing and evaluating the design and operating effectiveness of internal control based on the assessed risk. Our audits also included performing such other procedures as we considered necessary in the circumstances. We believe that our audits provide a reasonable basis for our opinions. SWN 89 FINAL GLOSSY v6 - 4000dpi Double.pdf 73 3/25/19 5:17 PM Definition and Limitations of Internal Control over Financial Reporting A company’s internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A company’s internal control over financial reporting includes those policies and procedures that (i) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (ii) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and (iii) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the company’s assets that could have a material effect on the financial statements. Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate. /s/PRICEWATERHOUSECOOPERS LLP Houston, Texas February 28, 2019 We have served as the Company’s auditor since 2002.

The Company is also focused on creating and capturing additional value through its marketing business and, until the Fayetteville Shale sale, its gathering business in Arkansas (“Midstream”). Southwestern conducts most of its business through subsidiaries and operates principally in two segments: E&P and Midstream. The Company also has drilling rigs located in Pennsylvania and West Virginia and provides oilfield products and services, principally serving its E&P operations. E&P. Southwestern’s primary business is the exploration for and production of natural gas, oil and NGLs, with ongoing operations focused on the development of unconventional natural gas and oil reservoirs located in Pennsylvania and West Virginia. The Company’s operations in northeast Pennsylvania, herein referred to as “Northeast Appalachia,” are primarily focused on the unconventional natural gas reservoir known as the Marcellus Shale. Operations in West Virginia and southwest Pennsylvania, herein referred to as “Southwest Appalachia,” are focused on the Marcellus Shale, the Utica and the Upper Devonian unconventional natural gas and oil reservoirs. Collectively, Southwestern refers to its properties located in Pennsylvania and West Virginia as the “Appalachian Basin.” Midstream. Southwestern’s marketing activities capture opportunities that arise through the marketing and transportation of natural gas, oil and NGLs produced in its E&P operations. In September 2018, the Company announced that it had signed an agreement to sell 100% of the equity in certain of its subsidiaries that owned and operated its Fayetteville Shale E&P and related midstream gathering assets for $1,865 million in cash, subject to customary closing adjustments (“Fayetteville Shale sale”). The sale closed December 3, 2018 resulting in net proceeds of approximately $1,650 million, following adjustments of $215 million primarily related to the net cash flows from the economic effective date to the closing date and certain other working capital adjustments, and is discussed in further detail in Note 3. The historical financial and operating results of the assets sold are included in these financial statements for the period of time during which we owned the assets. Basis of Presentation The consolidated financial statements included in this Annual Report present the Company’s financial position, results of operations and cash flows for the periods presented in accordance with accounting principles generally accepted in the United States (“GAAP”). The preparation of financial statements in accordance with GAAP requires management to make estimates and assumptions that affect the amounts of assets and liabilities and disclosure of contingent assets and liabilities, if any, at the date of the financial statements, and the amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. The Company evaluates subsequent events through the date the financial statements are issued. Certain reclassifications have been made to the prior year financial statements to conform to the 2018 presentation. In the first quarter of 2018, the Company adopted ASU 2017-07 which required that all non-service costs related to the Company’s pension plan be reclassified from general and administrative expenses to other income (loss), net for all periods presented. The adoption of ASU 2017-07 resulted in a reclassification of $5 million of curtailment and settlement costs from restructuring charges to other income (loss), net on the Company’s consolidated statements of operations for the year ended December 31, 2016. Principles of Consolidation The consolidated financial statements include the accounts of Southwestern and its wholly-owned subsidiaries. All significant intercompany accounts and transactions have been eliminated. In 2015, the Company purchased an 86% ownership in a limited partnership which owns and operates a gathering system in Northeast Appalachia. Because the Company owns a controlling interest in the partnership, the operating and financial results are consolidated with the Company’s E&P segment results. The investor’s share of the partnership activity is reported in retained earnings in the consolidated financial statements. Net income attributable to noncontrolling interest for the years ended December 31, 2018, 2017 and 2016 was insignificant. SWN 98 FINAL GLOSSY v6 - 4000dpi Double.pdf 82 3/25/19 5:17 PM Major Customers The Company sells the vast majority of its E&P natural gas, oil and NGL production to third-party customers through its marketing subsidiary. For the years ended December 31, 2018 and 2017, two subsidiaries of Royal Dutch Shell Plc in aggregate accounted for approximately 10.4% and 10.3%, respectively, of total natural gas, oil and NGL sales. In 2016, no single customer accounted for 10% or greater of our total sales. The Company believes that the loss of a major customer would not have a material adverse effect on its ability to sell its natural gas, oil and NGL production because alternative purchasers are available. Cash and Cash Equivalents Cash and cash equivalents are defined by the Company as short-term, highly liquid investments that have an original maturity of three months or less and deposits in money market mutual funds that are readily convertible into cash. Management considers cash and cash equivalents to have minimal credit and market risk as the Company monitors the credit status of the financial institutions holding its cash and marketable securities. The following table presents a summary of cash and cash equivalents as of December 31, 2018 and December 31, 2017: (in millions) Cash Marketable securities (1) Other cash equivalents Total (1) Consists of government stable value money market funds. (2) Consists of time deposits. For the years ended December 31, 2018 2017 $ $ 32 $ 169 – 201 $ 261 605 50 (2) 916 Certain of the Company’s cash accounts are zero-balance controlled disbursement accounts. The Company presents the outstanding checks written against these zero-balance accounts as a component of accounts payable in the accompanying consolidated balance sheets. Outstanding checks included as a component of accounts payable totaled $34 million and $17 million as of December 31, 2018 and 2017, respectively. Property, Depreciation, Depletion and Amortization Natural Gas and Oil Properties. The Company utilizes the full cost method of accounting for costs related to the exploration, development and acquisition of natural gas and oil properties. Under this method, all such costs (productive and nonproductive), including salaries, benefits and other internal costs directly attributable to these activities, are capitalized on a country-by-country basis and amortized over the estimated lives of the properties using the units-of-production method. These capitalized costs are subject to a ceiling test that limits such pooled costs, net of applicable deferred taxes, to the aggregate of the present value of future net revenues attributable to proved natural gas, oil and NGL reserves discounted at 10% (standardized measure). Any costs in excess of the ceiling are written off as a non-cash expense. The expense may not be reversed in future periods, even though higher natural gas, oil and NGL prices may subsequently increase the ceiling. Companies using the full cost method are required to use the average quoted price from the first day of each month from the previous 12 months, including the impact of derivatives designated for hedge accounting, to calculate the ceiling value of their reserves. Decreases in market prices as well as changes in production rates, levels of reserves, evaluation of costs excluded from amortization, future development costs and production costs could result in future ceiling test impairments. Costs associated with unevaluated properties are excluded from the amortization base until the properties are evaluated or impairment is indicated. The costs associated with unevaluated leasehold acreage and related seismic data, wells currently drilling and related capitalized interest are initially excluded from the amortization base. Leasehold costs are either transferred to the amortization base with the costs of drilling a well on the lease or are assessed at least annually for possible impairment or reduction in value. The Company’s decision to withhold costs from amortization and the timing of the transfer of those costs into the amortization base involves a significant amount of judgment and may be subject to changes over time based on several factors, including drilling plans, availability of capital, project economics and drilling results from adjacent acreage. At December 31, 2018, the Company had a total of $1,755 million of costs excluded from the amortization base, all of which related to its properties in the United States. Inclusion of some or all of these costs in the Company’s United States properties in the future, without adding any associated reserves, could result in additional ceiling test impairments. At December 31, 2018, using the average quoted price from the first day of each month from the previous 12 months for Henry Hub natural gas of $3.10 per MMBtu, West Texas Intermediate oil of $65.56 per barrel and NGLs of $17.64 per barrel, SWN 99 FINAL GLOSSY v6 - 4000dpi Double.pdf 83 3/25/19 5:17 PM adjusted for market differentials, the Company’s net book value of its United States natural gas and oil properties did not exceed the ceiling amount and did not result in a ceiling test impairment at December 31, 2018. The Company had no derivative positions that were designated for hedge accounting as of December 31, 2018. Using the average quoted price from the first day of each month from the previous 12 months for Henry Hub natural gas of $2.98 per MMBtu, West Texas Intermediate oil of $47.79 per barrel and NGLs of $14.41 per barrel, adjusted for market differentials, the Company’s net book value of its United States natural gas and oil properties did not exceed the ceiling amount and did not result in a ceiling test impairment at December 31, 2017. The Company had no derivative positions that were designated for hedge accounting as of December 31, 2017. The net book value of the Company’s United States and Canada natural gas and oil properties exceeded the ceiling by approximately $641 million (net of tax) at March 31, 2016, $297 million (net of tax) at June 30, 2016 and $506 million (net of tax) at September 30, 2016 and resulted in non-cash ceiling test impairments for the quarters ended those dates. Using the average quoted price from the first day of each month from the previous 12 months for Henry Hub natural gas of $2.48 per MMBtu, West Texas Intermediate oil of $39.25 per barrel and NGLs of $6.74 per barrel, adjusted for market differentials, the Company’s net book value of its United States natural gas and oil properties did not exceed the ceiling amount and did not results in a ceiling test impairment at December 31, 2016. The Company had no derivative positions that were designated for hedge accounting as of December 31, 2016. Gathering Systems. The Company’s investment in gathering systems was primarily in a system serving its Fayetteville Shale operations in Arkansas. These assets were included in the Fayetteville Shale sale that closed in December 2018. Capitalized Interest. Interest is capitalized on the cost of unevaluated natural gas and oil properties that are excluded from amortization. Asset Retirement Obligations. The Company owns natural gas and oil properties, which require expenditures to plug and abandon the wells and reclaim the associated pads when the wells are no longer producing. An asset retirement obligation associated with the retirement of a tangible long-lived asset is recognized as a liability in the period incurred or when it becomes determinable, with an associated increase in the carrying amount of the related long-lived asset. The cost of the tangible asset, including the asset retirement cost, is depreciated over the useful life of the asset. The asset retirement obligation is recorded at its estimated fair value, and accretion expense is recognized over time as the discounted liability is accreted to its expected settlement value. Impairment of Long-Lived Assets. The carrying value of non-full cost pool long-lived assets is evaluated for recoverability whenever events or changes in circumstances indicate that it may not be recoverable. In accordance with accounting guidance for Property, Plant and Equipment, assets held for sale are measured at the lower of carrying value or fair value less costs to sell. This accounting guidance does not apply to the Company’s full cost pool assets, which are governed under SEC Regulation S-X 4-10, and thus were not classified as held for sale. Because the assets excluding the full cost pool met the criteria for held for sale accounting in the third quarter of 2018 due to their inclusion in the Fayetteville Shale sale, the Company determined the carrying value of certain non-full cost pool assets exceeded the fair value less costs to sell. As a result, an impairment charge of $160 million was recorded for the year ended December 31, 2018, of which $145 million related to midstream gathering assets held for sale and $15 million related to E&P assets held for sale. Separately, the Company recorded an $11 million impairment of other non-core assets that were not included in the Fayetteville Shale sale, for the year ended December 31, 2018. Intangible Assets. The carrying value of intangible assets are evaluated for recoverability whenever events or changes in circumstances indicate that it may not be recoverable. Intangible assets are amortized over their useful life. The Company amortized $9 million of its marketing-related intangible asset in each of the years ended December 31, 2018, 2017 and 2016. Income Taxes The Company follows the asset and liability method of accounting for income taxes. Under this method, deferred tax assets and liabilities are recorded for the estimated future tax consequences attributable to the differences between the financial carrying amounts of existing assets and liabilities and their respective tax basis. Deferred tax assets and liabilities are measured using the tax rate expected to be in effect for the year in which those temporary differences are expected to reverse. The effect of a change in tax rates on deferred tax assets and liabilities is recognized in the year of the enacted rate change. Deferred income taxes are provided to recognize the income tax effect of reporting certain transactions in different years for income tax and financial reporting purposes. A valuation allowance is established to reduce deferred tax assets if it is more likely than not that the related tax benefits will not be realized. SWN 100 FINAL GLOSSY v6 - 4000dpi Double.pdf 84 3/25/19 5:17 PM The Company accounts for uncertainty in income taxes using a recognition and measurement threshold for tax positions taken or expected to be taken in a tax return. The tax benefit from an uncertain tax position is recognized when it is more likely than not that the position will be sustained upon examination by taxing authorities based on technical merits of the position. The amount of the tax benefit recognized is the largest amount of the benefit that has a greater than 50% likelihood of being realized upon ultimate settlement. The effective tax rate and the tax basis of assets and liabilities reflect management’s estimates of the ultimate outcome of various tax uncertainties. The Company recognizes penalties and interest related to uncertain tax positions within the provision (benefit) for income taxes line in the accompanying consolidated statements of operations. Additional information regarding uncertain tax positions along with the impact of recent tax reform legislation can be found in Note 10. Derivative Financial Instruments The Company uses derivative financial instruments to manage defined commodity price risks and does not use them for speculative trading purposes. The Company uses derivative instruments to financially protect sales of natural gas, oil and NGLs. In addition, the Company uses interest rate swaps to manage exposure to unfavorable interest rate changes. Since the Company does not designate its derivatives for hedge accounting treatment, gains and losses resulting from the settlement of derivative contracts have been recognized in gain (loss) on derivatives in the consolidated statements of operations when the contracts expire and the related physical transactions of the underlying commodity are settled. Additionally, changes in the fair value of the unsettled portion of derivative contracts are also recognized in gain (loss) on derivatives in the consolidated statement of operations. See Note 5 – “Derivatives and Risk Management” and Note 7 – “Fair Value Measurements” for a discussion of the Company’s hedging activities. Earnings Per Share Basic earnings per common share is computed by dividing net income (loss) attributable to common stock by the weighted average number of common shares outstanding during the reportable period. The diluted earnings per share calculation adds to the weighted average number of common shares outstanding: the incremental shares that would have been outstanding assuming the exercise of dilutive stock options, the vesting of unvested restricted shares of common stock, performance units and the assumed conversion of mandatory convertible preferred stock. An antidilutive impact is an increase in earnings per share or a reduction in net loss per share resulting from the conversion, exercise, or contingent issuance of certain securities. In July 2016, the Company completed an underwritten public offering of 98,900,000 shares of its common stock, with an offering price to the public of $13.00 per share. Net proceeds from the common stock offering were approximately $1,247 million, after underwriting discount and offering expenses. The proceeds from the offering were used to repay $375 million of the $750 million term loan entered into in November 2015 and to settle certain tender offers by purchasing an aggregate principal amount of approximately $700 million of the Company’s outstanding senior notes due in 2018. The remaining proceeds of the offering were used for general corporate purposes. In January 2015, the Company issued 34,500,000 depositary shares that entitled the holder to a proportional fractional interest in the rights and preferences of the mandatory convertible preferred stock, including conversion, dividend, liquidation and voting rights. The mandatory convertible preferred stock had the non-forfeitable right to participate on an as-converted basis at the conversion rate then in effect in any common stock dividends declared and, therefore, was considered a participating security. Accordingly, it has been included in the computation of basic and diluted earnings per share, pursuant to the two-class method. In the calculation of basic earnings per share attributable to common shareholders, earnings are allocated to participating securities based on actual dividend distributions received plus a proportionate share of undistributed net income attributable to common shareholders, if any, after recognizing distributed earnings. The Company’s participating securities do not participate in undistributed net losses because they are not contractually obligated to do so. On January 12, 2018, all outstanding shares of mandatory convertible preferred stock were converted to 74,998,614 shares of the Company’s common stock. FINAL GLOSSY v6 - 4000dpi Double.pdf 85 3/25/19 5:17 PM SWN 101 The Company declared dividends on its mandatory convertible preferred stock in the first, second and third quarters of 2017 that were settled partially in common stock for a total of 10,040,306 shares as well as each quarter in 2016 that were settled in common stock for a total of 9,917,799 shares. In 2018, the Company repurchased 39,061,269 of its outstanding common stock for approximately $180 million at an average price of $4.63 per share. The following table presents the computation of earnings per share for the years ended December 31, 2018, 2017 and 2016: (in millions, except share/per share amounts) Net income (loss) Mandatory convertible preferred stock dividend Participating securities – mandatory convertible preferred stock Net income (loss) attributable to common stock Number of common shares: Weighted average outstanding Issued upon assumed exercise of outstanding stock options Effect of issuance of non-vested restricted common stock Effect of issuance of non-vested performance units Weighted average and potential dilutive outstanding Earnings (loss) per common share: Basic Diluted For the years ended December 31, 2017 2016 2018 $ $ 537 – 2 535 $ $ 1,046 $ 108 123 815 $ (2,643) 108 – (2,751) 574,631,756 – 698,103 1,312,949 576,642,808 498,264,321 – 1,061,056 1,478,920 500,804,297 435,337,402 – – – 435,337,402 $ $ 0.93 0.93 $ $ 1.64 $ 1.63 $ (6.32) (6.32) The following table presents the common stock shares equivalent excluded from the calculation of diluted earnings per share for the years ended December 31, 2018, 2017 and 2016, as they would have had an antidilutive effect: Unexercised stock options Unvested share-based payment Performance units Mandatory convertible preferred stock Total Supplemental Disclosures of Cash Flow Information For the years ended December 31, 2017 2018 5,909,082 3,692,794 642,568 2,465,708 12,710,152 116,717 5,361,849 765,689 74,999,895 81,244,150 2016 3,692,697 959,233 884,644 74,999,895 80,536,469 The following table provides additional information concerning interest and income taxes paid as well as changes in noncash investing activities for the years ended December 31, 2018, 2017 and 2016: (in millions) Cash paid during the year for interest, net of amounts capitalized Cash paid (received) during the year for income taxes Increase (decrease) in noncash property additions Stock-Based Compensation For the years ended December 31, 2017 2016 2018 $ 135 $ 6 (42) $ 130 (5) 25 75 (15) 55 The Company accounts for stock-based compensation transactions using a fair value method and recognizes an amount equal to the fair value of the stock options and stock-based payment cost in either the consolidated statement of operations or capitalizes the cost into natural gas and oil properties or gathering systems included in property and equipment. Costs are capitalized when they are directly related to the acquisition, exploration and development activities of the Company’s natural gas and oil properties. See Note 13 for a discussion of the Company’s stock-based compensation. SWN 102 FINAL GLOSSY v6 - 4000dpi Double.pdf 86 3/25/19 5:17 PM Liability-Classified Awards The fair value of a liability-classified award is determined on a quarterly basis beginning at the grant date until final vesting. Changes in the fair value of liability-classified awards are recorded to general and administrative expense or capitalized expense over the vesting period of the award. The Company’s liability-classified performance unit awards include a performance condition based on cash flow per debt-adjusted share and two market conditions, one based on absolute total shareholder return and the other on relative total shareholder return as compared to a group of the Company’s peers. The fair values of the two market conditions are calculated by Monte Carlo models on a quarterly basis. Treasury Stock In the third quarter of 2018, the Company announced its intention to repurchase up to $200 million of its outstanding common stock using a portion of the net proceeds from the Fayetteville Shale sale. As of December 31, 2018, approximately $180 million has been spent to repurchase 39,061,269 shares at an average price of $4.63 per share. The Company maintains a non-qualified deferred compensation supplemental retirement savings plan for certain key employees whereby participants may elect to defer and contribute a portion of their compensation to a Rabbi Trust, as permitted by the plan. The Company includes the assets and liabilities of its supplemental retirement savings plan in its consolidated balance sheet. Shares of the Company’s common stock purchased under the non-qualified deferred compensation arrangement are held in the Rabbi Trust, are presented as treasury stock and are carried at cost. As of December 31, 2018 and 2017, 10,653 shares and 31,269 shares, respectively, were held in the Rabbi Trust and were accounted for as treasury stock. In 2018, 20,616 shares were released from the Rabbi Trust due to a reduction in our workforce. These shares are still held as treasury stock. Foreign Currency Translation The Company has designated the Canadian dollar as the functional currency for its activities in Canada. The cumulative translation effects of translating the accounts from the functional currency into the U.S. dollar at current exchange rates are included as a separate component of other comprehensive income within stockholders’ equity. New Accounting Standards Implemented in this Report In May 2014, the FASB issued Accounting Standards Update No. 2014-09, Revenue from Contracts with Customers (Topic 606) (ASC 606, as subsequently amended). ASC 606 supersedes the revenue recognition requirements in topic 605, Revenue Recognition, and requires entities to recognize revenue when control of the promised goods or services is transferred to customers at an amount that reflects the consideration to which an entity expects to be entitled to in exchange for those goods or services. The Company adopted ASC 606 with an effective date of January 2018 using the modified retrospective approach. For public entities, ASC 606 became effective for fiscal years beginning after December 15, 2017. The adoption of this standard did not have a material effect on the Company’s consolidated results of operations, financial position or cash flows. Additional disclosures regarding the nature, amount, timing and uncertainty of revenue and cash flow from contracts with customers are available in Note 4 – “Revenue Recognition”. In March 2017, the FASB issued Accounting Standards Update No. 2017-07, Compensation - Retirement Benefits (Topic 715) (“Update 2017-07”), which provides additional guidance on the presentation of net benefit cost in the statement of operations and on the components eligible for capitalization in assets, and requires retrospective adoption. The guidance requires employers to disaggregate the service cost component from the other components of net benefit cost. The service cost component of the net periodic benefit cost shall be reported in the same line item as other compensation costs arising from services rendered by the employees during the period, except for amounts capitalized. All other components of net benefit cost shall be presented outside of a subtotal for income from operations. The Company adopted Update 2017-07 during the first quarter of 2018 resulting in no material impact to its consolidated statement of operations, financial position or cash flows. The non-service cost components of net periodic benefit cost are no longer presented as a component of general and administrative expense, but are now presented as a component of Other Income, Net for the years ended December 31, 2018, 2017 and 2016, and are disclosed in Note 12 – “Retirement and Employment Benefit Plans”. The Company ceased capitalizing the non-service components of net periodic benefit costs prospectively as of the beginning of the first quarter of 2018. FINAL GLOSSY v6 - 4000dpi Double.pdf 87 3/25/19 5:17 PM SWN 103 In August 2016, the FASB issued Accounting Standards Update No. 2016-15, Statement of Cash Flows (Topic 230) (“Update 2016-15”), which seeks to reduce the existing diversity in practice in how certain cash receipts and cash payments are presented and classified in the statement of cash flows. The Company adopted this update during the first quarter of 2018 resulting in no impact on its consolidated statement of cash flows. In February 2018, the FASB issued Accounting Standards Update No. 2018-02 that will amend the FASB Accounting Standards relating to tax effects in accumulated other comprehensive income (Topic 220) (“Updated 2018-02”). Update 2018-02 permits a company to reclassify the stranded income tax effects of the Tax Reform Act on items within accumulated comprehensive income to retained earnings. Although the amendments in Update 2018-02 are effective for fiscal years beginning after December 15, 2018, including interim periods within those fiscal years, the Company elected to early adopt the amendments of Update 2018-02 in the third quarter of 2018. The implementation did not have a material impact on the Company’s consolidated statement of operations, financial position or cash flows due to the tax valuation allowance currently in place. Any adjustments required under this update were fully offset by valuation allowance adjustments for both continuing operations and accumulated other comprehensive income. New Accounting Standards Not Yet Implemented in this Report In February 2016, the FASB issued Accounting Standards Update No. 2016-02, Leases (Topic 842) (“Update 2016-02”), which seeks to increase transparency and comparability among organizations by, among other things, recognizing lease assets and lease liabilities on the balance sheet for leases classified as operating leases under previous GAAP and disclosing key information about leasing arrangements. The codification was amended through additional ASUs. Through the year ended December 31, 2018, the Company finalized its contract reviews for leases in effect at year-end, drafted its accounting policies, evaluated the new disclosure requirements and implemented a software solution. Upon adoption, the Company expects to recognize a discounted right-of-use asset and corresponding lease liability between $95 million and $115 million. The Company continues to review new contracts commenced during 2019 to determine the appropriate lease accounting treatment where applicable. ASC 842 allows issuers to elect the date of initial application as either the beginning of the period of adoption or the beginning of the earliest comparative period presented in the financial statements. The Company plans to elect the period of adoption, January 1, 2019, as its initial application date which would not result in restating prior comparative periods. The adoption of this standard is not expected to materially change the Company’s consolidated statement of operations or its consolidated statement of cash flows. The Form 10-Q filing for the quarter ended March 31, 2019 will include the full impact of ASC 842, along with the presentation of the discounted right-of-use asset and lease liability on the consolidated balance sheet.

Affected employees were offered a severance package, which included a one-time cash payment depending on length of service and, if applicable, the current value of a portion of equity awards that were forfeited. Although the plan was substantially implemented by the end of 2018, certain employees were retained into 2019. As of December 31, 2018, a liability of $1 million for severance payments has been accrued related to the reduction in workforce. In January 2016, the Company announced a 40% workforce reduction as a result of lower anticipated drilling activity. This reduction was substantially completed in the first quarter of 2016. In April 2016, the Company also partially restructured executive management, which was substantially completed in the second quarter of 2016. Severance payments and other separation costs related to restructuring were substantially completed by the end of 2016. The following table presents a summary of the restructuring charges related to workforce reduction plans included in Operating Income (Loss) for the years ended December 31, 2018, 2017 and 2016: (in millions) Severance (including payroll taxes) Stock-based compensation Other benefits Outplacement services, other Total reduction in workforce-related restructuring charges (2) For the years ended December 31, 2017 2016 (1) 2018 $ $ 21 $ – – 2 23 $ – $ – – – – $ 44 24 3 2 73 (1) Does not include $5 million non-cash charges related to the curtailment and settlement of the pension and other postretirement benefit plans for the year ended December 31, 2016 presented in other income (loss), net in the consolidated statements of operations. See Note 12 for additional details regarding the Company’s retirement and employee benefit plans. (2) Total restructuring charges were $21 million and $2 million for the Company’s E&P and Midstream segments, respectively, for the year ended December 31, 2018 and $70 million and $3 million for the Company’s E&P and Midstream segments, respectively, for the year ended December 31, 2016. Fayetteville Shale Sale-Related In December 2018, the Company closed on the sale of the equity in certain of its subsidiaries that owned and operated its Fayetteville Shale E&P and related midstream gathering assets in Arkansas. As part of this transaction, most employees associated with those assets became employees of the buyer although the employment of some was, or will be, terminated. All affected employees were offered a severance package, which included a one-time cash payment depending on length of service and, if applicable, the current value of a portion of equity awards that were forfeited. Additionally, a small number of employees have been retained to provide assistance through the divestiture transition period and will receive a similar severance package upon the deferred termination of their employment. As of December 31, 2018, a liability of $4 million for severance payments has been accrued related to remaining Fayetteville Shale sale-related employment terminations. As a result of the Fayetteville Shale sale, the Company relocated certain employees and infrastructure to other areas. In addition to personnel-related costs, the Company has also incurred charges related to office consolidation and has recognized these costs as restructuring charges.

SWN 105 FINAL GLOSSY v6 - 4000dpi Double.pdf 89 3/25/19 5:17 PM (3) DIVESTITURES On August 30, 2018, the Company entered into an agreement with Flywheel Energy Operating, LLC to sell 100% of the equity in the Company’s subsidiaries that owned and operated its Fayetteville Shale E&P and related midstream gathering assets for $1,865 million in cash, subject to customary closing adjustments, with an economic effective date of July 1, 2018. During the third quarter of 2018, the Company classified the non-full cost pool portion of these assets as held for sale and recorded an impairment charge of $160 million, of which $145 million related to midstream gathering assets held for sale and $15 million related to E&P assets held for sale. On December 3, 2018, the Company closed on the Fayetteville Shale sale and received approximately $1,650 million, which included preliminary purchase price adjustments of approximately $215 million primarily related to the net cash flows from the economic effective date to the closing date. The Company allocated the sale proceeds to gain on sale for the non- full cost pool assets and to capitalized costs for the full cost pool assets based on the proportion of the estimated fair values of the underlying assets. The fair values of these assets was estimated primarily using an income approach. Consequently, the Company recognized a gain on the sale of non-full cost pool assets of $17 million and a reduction of $887 million to its full cost pool assets. As the sale did not involve a significant change in proved reserves or significantly alter the relationship between capitalized costs and proved reserves, the Company recognized no gain or loss related to the full cost pool assets sold. As part of the Fayetteville Shale sale agreement, the Company entered into certain natural gas derivative positions which were subsequently novated to the buyer in conjunction with finalization of the sale. The unrealized fair value of these derivatives at the closing of the sale in December 2018 was a net liability of $151 million which was transferred to the buyer. The unrealized loss associated with the novated positions was offset by the gain that the Company recognized when the liability was transferred to the buyer. These offsetting amounts were recognized on the consolidated statements of operations in Gain on sale of assets, net. In addition, the Company paid $22 million in premiums for these novated derivatives which was recorded as a loss in Gain on sale of assets, net in 2018. The Company retained certain contractual commitments related to firm transportation, with the buyer obligated to pay the transportation provider directly for these charges. As of December 31, 2018, approximately $221 million of these contractual commitments remain of which the Company will reimburse the buyer for certain of these potential obligations up to approximately $102 million through 2020 depending on the buyer’s actual use, and has recorded an $88 million liability for the estimated future payments. The buyer will also assume future asset retirement obligations related to the operations sold. From the proceeds received, $914 million was used to repurchase $900 million of the Company’s outstanding senior notes, including premiums and $9 million in accrued interest paid, and $180 million was used to repurchase approximately 39 million shares of the Company’s outstanding common stock as of December 31, 2018. The Company intends to use the remaining net proceeds from the sale to supplement Appalachian Basin development, return capital to shareholders and for general corporate purposes. (4) REVENUE RECOGNITION Effective January 1, 2018, the Company adopted Accounting Standards Codification (“ASC”) 606, “Revenue from Contracts with Customers,” using the modified retrospective method applied to those contracts which were not completed as of January 1, 2018. Under the modified retrospective method, The Company recognizes the cumulative effect of initially applying the new revenue standard as an adjustment to the opening balance of retained earnings; however, no material adjustment was required as a result of adopting ASC 606. Results for reporting periods beginning on January 1, 2018 are presented under the new revenue standard. The comparative information has not been restated and continues to be reported under the accounting standards in effect for those periods. The Company performed an analysis of the impact of adopting ASC 606 across all revenue streams and did not identify any changes to its revenue recognition policies that would result in a material impact to its consolidated financial statements. SWN 106 FINAL GLOSSY v6 - 4000dpi Double.pdf 90 3/25/19 5:17 PM Revenues from Contracts with Customers Natural gas and liquids. Natural gas, oil and NGL sales are recognized when control of the product is transferred to the customer at a designated delivery point. The pricing provisions of the Company’s contracts are primarily tied to a market index with certain adjustments based on factors such as delivery, quality of the product and prevailing supply and demand conditions in the geographic areas in which the Company operates. Under the Company’s sales contracts, the delivery of each unit of natural gas, oil and NGLs represents a separate performance obligation, and revenue is recognized at the point in time when the performance obligations are fulfilled. There is no significant financing component to the Company’s revenues as payment terms are typically within 30 to 60 days of control transfer. Furthermore, consideration from a customer corresponds directly with the value to the customer of the Company’s performance completed to date. As a result, the Company recognizes revenue in the amount to which the Company has a right to invoice and has not disclosed information regarding its remaining performance obligations. The Company records revenue from its natural gas and liquids production in the amount of its net revenue interest in sales from its properties. Accordingly, natural gas and liquid sales are not recognized for deliveries in excess of the Company’s net revenue interest, while natural gas and liquid sales are recognized for any under-delivered volumes. Production imbalances are generally recorded as receivables and payables and not contract assets or contract liabilities as the imbalances are between the Company and other working interest owners, not the end customer. Marketing. The Company, through its marketing affiliate, generally markets natural gas, oil and NGLs for its affiliated E&P companies as well as other joint owners who choose to market with Southwestern. In addition, the Company markets some products purchased from third parties. Marketing revenues for natural gas, oil and NGL sales are recognized when control of the product is transferred to the customer at a designated delivery point. The pricing provisions of the Company’s contracts are primarily tied to a market index with certain adjustments based on factors such as delivery, quality of the product and prevailing supply and demand conditions. Under the Company’s marketing contracts, the delivery of each unit of natural gas, oil and NGLs represents a separate performance obligation, and revenue is recognized at the point in time when the performance obligations are fulfilled. Customers are invoiced and revenues are recorded each month as natural gas, oil and NGLs are delivered, and payment terms are typically within 30 to 60 days of control transfer. Furthermore, consideration from a customer corresponds directly with the value to the customer of the Company’s performance completed to date. As a result, the Company recognizes revenue in the amount to which the Company has a right to invoice and has not disclosed information regarding its remaining performance obligations. Gas gathering. Prior to the Fayetteville Shale sale, the Company, through a subsidiary included in the Fayetteville Shale sale, gathered natural gas in Arkansas pursuant to a variety of contracts with customers, including an affiliated E&P company. The performance obligations for gas gathering services included delivery of each unit of natural gas to the designated delivery point, which may include treating of certain natural gas units to meet interstate pipeline specifications. Revenue was recognized at the point in time when performance obligations were fulfilled. Under the Company’s gathering contracts, customers were invoiced and revenue was recognized each month based on the volume of natural gas transported and treated at a contractually agreed upon price per unit. Payment terms were typically within 30 to 60 days of completion of the performance obligations. Furthermore, consideration from a customer corresponded directly with the value to the customer of the Company’s performance completed to date. As a result, the Company recognized revenue in the amount to which the Company had a right to invoice and therefore had not disclosed information regarding its remaining performance obligations. Any imbalances were settled on a monthly basis by cashing-out with the respective shipper. Accordingly, there were no contract assets or contract liabilities related to the Company’s gas gathering revenues. The natural gas gathering operations in Arkansas were included in the Fayetteville Shale sale that closed in December 2018.

The Company has no contract assets or contract liabilities associated with its revenues from contracts with customers. (5) DERIVATIVES AND RISK MANAGEMENT The Company is exposed to volatility in market prices and basis differentials for natural gas, oil and NGLs which impacts the predictability of its cash flows related to the sale of those commodities. These risks are managed by the Company’s use of certain derivative financial instruments. As of December 31, 2018, the Company’s derivative financial instruments consisted of fixed price swaps, two-way costless collars, three-way costless collars, basis swaps, call options and interest rate swaps. During 2016, the Company settled all of its purchased put options. A description of the Company’s derivative financial instruments is provided below: Fixed price swaps If the Company sells a fixed price swap, the Company receives a fixed price for the contract and pays a floating market to the counterparty. If the Company purchases a fixed price swap, the Company receives a floating market price for the contract and pays a fixed price to the counterparty. Two-way costless collars Arrangements that contain a fixed floor price (purchased put option) and a fixed ceiling price (sold call option) based on an index price which, in aggregate, have no net cost. At the contract settlement date, (1) if the index price is higher than the ceiling price, the Company pays the counterparty the difference between the index price and ceiling price, (2) if the index price is between the floor and ceiling prices, no payments are due from either party, and (3) if the index price is below the floor price, the Company will receive the difference between the floor price and the index price. Three-way costless collars Basis swaps Call options Arrangements that contain a purchased put option, a sold call option and a sold put option based on an index price which, in aggregate, have no net cost. At the contract settlement date, (1) if the index price is higher than the sold call strike price, the Company pays the counterparty the difference between the index price and sold call strike price, (2) if the index price is between the purchased put strike price and the sold call strike price, no payments are due from either party, (3) if the index price is between the sold put strike price and the purchased put strike price, the Company will receive the difference between the purchased put strike price and the index price, and (4) if the index price is below the sold put strike price, the Company will receive the difference between the purchased put strike price and the sold put strike price. Arrangements that guarantee a price differential for natural gas from a specified delivery point. If the Company sells a basis swap, the Company receives a payment from the counterparty if the price differential is greater than the stated terms of the contract and pays the counterparty if the price differential is less than the stated terms of the contract. If the Company purchases a basis swap, the Company pays the counterparty if the price differential is greater than the state terms of the contract and receives a payment from the counterparty if the price differential is less than the stated terms of the contract. The Company purchases and sells call options in exchange for a premium. If the Company purchases a call option, the Company receives from the counterparty the excess (if any) of the market price over the strike price of the call option at the time of settlement, but if the market price is below the call’s strike price, no payment is due from either party. If the Company sells a call option, the Company pays the counterparty the excess (if any) of the market price over the strike price at the time of settlement, but if the market price is below the call’s strike price, no payment is due from either party. Interest rate swaps Interest rate swaps are used to fix or float interest rates on existing or anticipated indebtedness. The purpose of these instruments is to manage the Company’s existing or anticipated exposure to unfavorable interest rate changes. SWN 109 FINAL GLOSSY v6 - 4000dpi Double.pdf 93 3/25/19 5:17 PM The Company chooses counterparties for its derivative instruments that it believes are creditworthy at the time the transactions are entered into, and the Company actively monitors the credit ratings and credit default swap rates of these counterparties where applicable. However, there can be no assurance that a counterparty will be able to meet its obligations to the Company. The Company presents its derivative positions on a gross basis and does not net the asset and liability positions where counterparty netting arrangements contain provisions for net settlement. As part of the Fayetteville Shale sale agreement, the Company entered into certain natural gas derivative positions which were subsequently novated to the buyer in conjunction with finalization of the sale. The unrealized fair value of these derivatives at the closing of the sale in December 2018 was a net liability of $151 million which was transferred to the buyer. The unrealized loss associated with the novated positions was offset by the gain that the Company recognized when the liability was transferred to the buyer. These offsetting amounts were recognized on the consolidated statements of operations in Gain on sale of assets, net. In addition, the Company paid $22 million in premiums for these novated derivatives which was recorded as a loss in Gain on sale of assets, net in 2018. The derivatives that were novated to the buyer are not included in the tables below. The following table provides information about the Company’s financial instruments that are sensitive to changes in commodity prices and that are used to protect the Company’s exposure.

At December 31, 2018, the net fair value of the Company’s financial instruments related to commodities was a $51 million asset. The net fair value of the Company’s interest rate swaps was a $1 million asset as of December 31, 2018. As of December 31, 2018, the Company had no positions designated for hedge accounting treatment. Gains and losses on derivatives that are not designated for hedge accounting treatment, or that do not meet hedge accounting requirements, are SWN 111 FINAL GLOSSY v6 - 4000dpi Double.pdf 95 3/25/19 5:17 PM recorded as a component of gain (loss) on derivatives on the consolidated statements of operations. Accordingly, the gain (loss) on derivatives component of the statement of operations reflects the gains and losses on both settled and unsettled derivatives. The Company calculates gains and losses on settled derivatives as the summation of gains and losses on positions which have settled within the reporting period. Only the settled gains and losses are included in the Company’s realized commodity price calculations. The Company is a party to interest rate swaps that were entered into to mitigate the Company’s exposure to volatility in interest rates. The interest rate swaps have a notional amount of $170 million and expire in June 2020. The Company did not designate the interest rate swaps for hedge accounting treatment. Changes in the fair value of the interest rate swaps are included in gain (loss) on derivatives on the consolidated statements of operations.

(7) FAIR VALUE MEASUREMENTS Assets and liabilities measured at fair value on a recurring basis The carrying amounts and estimated fair values of the Company’s financial instruments as of December 31, 2018 and 2017 were as follows: (in millions) Cash and cash equivalents 2018 revolving credit facility due April 2023 2016 term loan facility due December 2020 (1) (2) Senior notes (1)(3) Derivative instruments, net (1) Excludes unamortized debt issuance costs and debt discounts. December 31, 2018 December 31, 2017 Carrying Amount Fair Value Carrying Amount Fair Value $ 201 $ – – 2,342 52 $ 201 – – 2,190 52 $ 916 – 1,191 3,242 77 (4) 916 – 1,191 3,358 77 (4) (2) (3) (4) In April 2018, the Company replaced its 2016 credit facility with a new 2018 credit facility and repaid the $1,191 million secured term loan balance in full. In December 2018, the Company repurchased $900 million of certain of its outstanding senior notes with a portion of the net proceeds from the Fayetteville Shale sale. Includes $1 million in premiums paid related to certain natural gas call options recognized as a component of derivative assets within current assets on the consolidated balance sheet. The carrying values of cash and cash equivalents, including marketable securities, accounts receivable, other current assets, accounts payable and other current liabilities on the consolidated balance sheets approximate fair value because of their short-term nature. For debt and derivative instruments, the following methods and assumptions were used to estimate fair value: Debt: The fair values of the Company’s senior notes were based on the market value of the Company’s publicly traded debt as determined based on the market prices of the Company’s senior notes. These instruments were previously classified as a Level 2 measurement but substantially all senior notes were updated to a Level 1 in the second quarter of 2018 as the market activity of the Company’s debt has resulted in timely quoted prices. The 4.05% Senior Notes due January 2020 remain a Level 2 measurement due to relative market inactivity. The carrying values of the borrowings under the Company’s revolving credit facility (to the extent utilized) and previous term loan facility approximate fair value because the interest rate is variable and reflective of market rates. The Company considers the fair value of its revolving credit facility to be a Level 1 measurement on the fair value hierarchy. Derivative Instruments: The fair value of all derivative instruments is the amount at which the instrument could be exchanged currently between willing parties. The amounts are based on quoted market prices, best estimates obtained from counterparties and an option pricing model, when necessary, for price option contracts. SWN 114 FINAL GLOSSY v6 - 4000dpi Double.pdf 98 3/25/19 5:17 PM The fair value hierarchy prioritizes the inputs to valuation techniques used to measure fair value. As presented in the tables below, this hierarchy consists of three broad levels: Level 1 valuations – Consist of unadjusted quoted prices in active markets for identical assets and liabilities and have the highest priority. Level 2 valuations – Consist of quoted market information for the calculation of fair market value. Level 3 valuations – Consist of internal estimates and have the lowest priority. The Company has classified its derivatives into these levels depending upon the data utilized to determine their fair values. The Company’s fixed price swaps (Level 2) are estimated using third-party discounted cash flow calculations using the NYMEX futures index for natural gas and oil derivatives and Oil Price Information Services (“OPIS”) for ethane and propane derivatives. The Company utilizes discounted cash flow models for valuing its interest rate derivatives (Level 2). The net derivative values attributable to the Company’s interest rate derivative contracts as of December 31, 2018 are based on (i) the contracted notional amounts, (ii) active market-quoted London Interbank Offered Rate (“LIBOR”) yield curves and (iii) the applicable credit-adjusted risk-free rate yield curve. The Company’s call options, two-way costless collars and three-way costless collars (Level 2) are valued using the Black-Scholes model, an industry standard option valuation model that takes into account inputs such as contract terms, including maturity, and market parameters, including assumptions of the NYMEX and OPIS futures index, interest rates, volatility and credit worthiness. The Company’s basis swaps (Level 2) are estimated using third-party calculations based upon forward commodity price curves. These instruments were previously classified as a Level 3 measurement in the fair value hierarchy but were updated to a Level 2 measurement in the second quarter of 2018 as a result of the Company’s ability to derive volatility inputs and forward commodity price curves from directly observable sources. Inputs to the Black-Scholes model, including the volatility input are obtained from a third-party pricing source, with independent verification of the most significant inputs on a monthly basis. An increase (decrease) in volatility would result in an increase (decrease) in fair value measurement, respectively. Assets and liabilities measured at fair value on a recurring basis are summarized below: December 31, 2018 Fair Value Measurements Using: Quoted Prices in Active Markets (Level 1) Significant Other Observable Inputs (Level 2) Significant Unobservable Inputs (Level 3) Assets (Liabilities) at Fair Value $ (in millions) Assets Fixed price swap – natural gas Fixed price swap – oil Fixed price swap – propane Fixed price swap – ethane Two-way costless collar – natural gas Two-way costless collar – oil Three-way costless collar – natural gas Basis swap – natural gas Purchased call option – natural gas Interest rate swap Liabilities Purchased fixed price swap – oil Fixed price swap – natural gas Fixed price swap – ethane Two-way costless collar – natural gas Two-way costless collar – oil Three-way costless collar – natural gas Basis swap – natural gas Sold call option – natural gas Total $ – $ – – – – – – – – – – – – – – – – – – $ 38 $ 19 11 8 11 11 75 11 6 1 (6) (10) (3) (7) (1) (68) (22) (22) 52 $ – – – – – – – – – – – – – – – – – – – $ $ 38 19 11 8 11 11 75 11 6 1 (6) (10) (3) (7) (1) (68) (22) (22) 52 SWN 115 FINAL GLOSSY v6 - 4000dpi Double.pdf 99 3/25/19 5:17 PM (in millions) Assets December 31, 2017 Fair Value Measurements Using: Quoted Prices in Active Markets (Level 1) Significant Other Observable Inputs (Level 2) Significant Unobservable Inputs (Level 3) Assets (Liabilities) at Fair Value Fixed price swap – natural gas Two-way costless collar – natural gas Three-way costless collar – natural gas Purchased call option – natural gas (1) Basis swap – natural gas Liabilities Fixed price swap – natural gas Two-way costless collar – natural gas Three-way costless collar – natural gas Basis swap – natural gas Sold call option – natural gas Interest rate swap Total $ $ – $ – – – – – – – – – – – $ 56 $ – – – – (1) – – – – (1) 54 $ $ – 5 121 3 2 – (1) (66) (23) (18) – 23 $ 56 5 121 3 2 (1) (1) (66) (23) (18) (1) 77 (1) Includes $1 million in premiums paid related to certain natural gas call options recognized as a component of derivative assets within current assets on the consolidated balance sheets at December 31, 2017. The table below presents reconciliations for the change in net fair value of derivative assets and liabilities measured at fair value on a recurring basis using significant unobservable inputs (Level 3) for the years ended December 31, 2018 and 2017. The fair values of Level 3 derivative instruments are estimated using proprietary valuation models that utilize both market observable and unobservable parameters. Level 3 instruments presented in the table consisted of net derivatives valued using pricing models incorporating assumptions that, in the Company’s judgment, reflected reasonable assumptions a marketplace participant would have used as of December 31, 2018 and 2017. For the years ended December 31, 2018 2017 $ 22 $ (195) (17) 1 (6) – – $ $ 199 18 – 22 217 (in millions) Balance at beginning of year Total gains (losses): Included in earnings Settlements (1) Transfers into/out of Level 3 (2) Balance at end of period Change in gains (losses) included in earnings relating to derivatives still held as of December 31 $ $ (1) Includes $1 million and $5 million amortization of premiums paid related to certain natural gas call options for the years ended December 31, 2018 and 2017, respectively. (2) Commodity derivatives previously presented as Level 3 were transferred to Level 2 in the second quarter of 2018 as the Company moved from using proprietary volatility inputs and forward curves to more widely available published information, increasing market observability. See Note 12 for a discussion of the fair value measurement of the Company’s pension plan assets. Assets and liabilities measured at fair value on a nonrecurring basis As further discussed in Note 3, the Company’s announcement of the Fayetteville Shale sale resulted in the reclassification of certain related assets and liabilities to held for sale on its balance sheet in the third quarter of 2018. Because the non-full cost pool assets met the criteria for held for sale accounting in the third quarter of 2018 due to their inclusion in the Fayetteville Shale sale, the Company determined the carrying value of certain non-full cost pool assets exceeded the carrying value less costs to sell. As a result, an impairment charge of $160 million was recorded for the year ended December 31, 2018, of which $145 million related to midstream gathering assets held for sale and $15 million related to E&P assets held for sale. Separately, the Company recorded an $11 million impairment of other non-core assets that were not included in the Fayetteville Shale sale, for the year ended December 31, 2018. The estimated fair value of the gathering assets was based on an estimated discounted cash flow model and market assumptions. The significant Level 3 assumptions used in the calculation of estimated discounted cash flows included in future rates of production, inflation factors and risk adjusted discount rates. These impairments are included in Net Income (Loss) from Operations in the accompanying consolidated statements of operations. On December 3, 2018, the Company closed on the Fayetteville Shale sale. Consequently, the SWN 116 FINAL GLOSSY v6 - 4000dpi Double.pdf 100 3/25/19 5:17 PM Company recognized a net gain on the sale of non-full cost pool assets of $17 million, which consisted of a gain on the Midstream segment of $35 million and a loss on the E&P segment of $18 million.

(2) In February and June 2016, Moody’s and S&P downgraded certain senior notes, which increased the interest rates by 175 basis points effective July 2016. As a result of the downgrades, interest rates increased to 5.80% for the 2020 Notes and 6.70% for the 2025 Notes. In April and May 2018, S&P and Moody’s upgraded certain senior notes. As a result of these upgrades, interest rates decreased to 5.30% for the 2020 Notes and 6.20% for the 2025 Notes effective July 2018. The first coupon payment to the bondholders at the lower interest rate was paid in January 2019. (3) In December 2018, the Company repurchased $40 million of its 4.05% senior notes due January 2020, $787 million of its 4.10% senior notes due March 2022 and $73 million of its 4.95% senior notes due January 2025.

Under the revolving credit facility, the Company had a borrowing capacity of $2.0 billion. The revolving credit facility was unsecured and was not guaranteed by any subsidiaries. In June 2016, this credit facility was substantially exchanged for a new credit facility comprised of a $1,191 million secured term loan and a new $743 million revolving credit facility. The borrowing capacity of the original 2013 credit agreement was reduced from $2.0 billion to $66 million, remained unsecured and the maturity remained December 2018. On April 26, 2018 the Company replaced its 2016 credit facility with the 2018 credit facility and terminated the 2013 credit facility. 2016 Credit Facility In June 2016, the Company reduced its existing $2.0 billion unsecured revolving credit facility, entered into in December 2013, to $66 million and entered into a new credit agreement for $1,934 million, consisting of a $1,191 million secured term loan and a new $743 million unsecured revolving credit facility, maturing in December 2020. Concurrent with the closing of the new 2018 credit facility agreement on April 26, 2018, the Company repaid the $1,191 million secured term loan balance and recognized a loss on early debt extinguishment of $8 million on the consolidated income statement related to the unamortized issuance expense. In addition, approximately $4 million of unamortized issuance expense associated with the closed $743 million revolving credit facility was carried forward into the unamortized issuance expenses of the 2018 credit facility. At December 31, 2017, the $1,191 million secured term loan was fully drawn, there were no borrowings under the revolving credit facility, but $323 million in letters of credit was outstanding under the 2016 revolving credit facility. 2018 Revolving Credit Facility In April 2018, as part of the Company’s strategic effort to simplify the capital structure, increase financial flexibility and reduce costs, the Company replaced its 2016 credit facility (which consisted of a $1,191 million secured term loan and an unsecured $743 million revolving credit facility) with a new revolving credit facility (the “2018 credit facility”). The 2018 credit facility has an aggregate maximum revolving credit amount of $3.5 billion, and at December 31, 2018, had a current borrowing base of $2.1 billion with a current aggregate commitment of $2.0 billion. The borrowing base is subject to redetermination twice a year in April and October. The 2018 credit facility matures in April 2023 and is secured by substantially all of the assets owned by the Company and its subsidiaries. Loans under the 2018 credit facility are subject to varying rates of interest based on whether the loan is a Eurodollar loan or an alternate base rate loan. Eurodollar loans bear interest at the Eurodollar rate, which is adjusted LIBOR for such interest period plus the applicable margin (as those terms are defined in the 2018 credit facility documentation). The applicable margin for Eurodollar loans under the 2018 credit facility ranges from 1.50% to 2.50% based on the Company’s utilization of the borrowing base under the 2018 credit facility. Alternate base rate loans bear interest at the alternate base rate plus the applicable margin. The applicable margin for alternate base rate loans under the 2018 credit facility ranges from 0.50% to 1.50% based on the Company’s utilization of the borrowing base under the 2018 credit facility. The 2018 credit facility contains customary representations and warranties and contains covenants including, among others, the following: • • • • a prohibition against incurring debt, subject to permitted exceptions; a restriction on creating liens on assets, subject to permitted exceptions; restrictions on mergers and asset dispositions; restrictions on use of proceeds, investments, transactions with affiliates, or change of principal business; and • maintenance of the following financial covenants, commencing with the fiscal quarter ended June 30, 2018: 1. Minimum current ratio of no less than 1.00 to 1.00, whereby current ratio is defined as the Company’s consolidated current assets (including unused commitments under the credit agreement, but excluding non-cash derivative assets) to consolidated current liabilities (excluding non-cash derivative obligations and current maturities of long-term debt). SWN 118 FINAL GLOSSY v6 - 4000dpi Double.pdf 102 3/25/19 5:17 PM 2. Maximum total net leverage ratio of no less than (i) with respect to each fiscal quarter ending during the period from June 30, 2018 through March 31, 2019, 4.50 to 1.00, (ii) with respect to each fiscal quarter ending during the period from June 30, 2019 through March 31, 2020, 4.25 to 1.00, and (iii) with respect to each fiscal quarter ending on or after June 30, 2020, 4.00 to 1.00. Total net leverage ratio is defined as total debt less cash on hand (up to the lesser of 10% of credit limit or $150 million) divided by consolidated EBITDAX for the last four consecutive quarters. EBITDAX, as defined in the Company’s 2018 credit agreement, excludes the effects of interest expense, depreciation, depletion and amortization, income tax, any non-cash impacts from impairments, certain non-cash hedging activities, stock-based compensation expense, non-cash gains or losses on asset sales, unamortized issuance cost, unamortized debt discount and certain restructuring costs. The 2018 credit facility contains customary events of default that include, among other things, the failure to comply with the financial covenants described above, non-payment of principal, interest or fees, violation of covenants, inaccuracy of representations and warranties, bankruptcy and insolvency events, material judgments and cross-defaults to material indebtedness. If an event of default occurs and is continuing, all amounts outstanding under the 2018 credit facility may become immediately due and payable. In the fourth quarter of 2018, the Company entered into hedges that, when added to existing hedges including hedges put in place as part of the Fayetteville Shale sale that the buyer was obligated to assume at closing of that sale, exceeded a cap on hedges for the month of December 2018 under a covenant under the Company’s credit agreement. In conjunction with the closing, the buyer paid for the settlement of the December 2018 hedges it was to assume. The lenders have subsequently waived all matters associated with this default. Otherwise, as of December 31, 2018, the Company was in compliance with all of the remaining covenants of this credit agreement in all material respects. Each United States domestic subsidiary of the Company for which the Company owns 100% of its equity guarantees the 2018 credit facility. Pursuant to requirements under the indentures governing the Company’s senior notes, each subsidiary that became a guarantor of the 2018 credit facility also became a guarantor of each of the Company’s senior notes. See Note 15 for the Company’s Condensed Consolidated Financial Information, presented in accordance with Rule 3-10 of Regulation S-X. At the closing of the Fayetteville Shale sale, its subsidiaries being sold were released from these guarantees. As of December 31, 2018, the Company had $112 million in letters of credit and no borrowings outstanding under the 2018 revolving credit facility. Senior Notes In January 2015, the Company completed a public offering of $850 million aggregate principal amount of its 4.05% Senior Notes due 2020 (the “2020 Notes”) and $1.0 billion aggregate principal amount of its 4.95% Senior Notes due 2025 (the “2025 Notes” together with the 2020 Notes, the “Notes”). The interest rates on the Notes are determined based upon the public bond ratings from Moody’s and S&P. Downgrades on the Notes from either rating agency increase interest costs by 25 basis points per downgrade level and upgrades decrease interest costs by 25 basis points per upgrade level, up to the stated coupon rate, on the following semi-annual bond interest payment. In February and June 2016, Moody’s and S&P downgraded the Notes, which increased the interest rates by 175 basis points effective July 2016. As a result of these downgrades, interest rates increased to 5.80% for the 2020 Notes and 6.70% for the 2025 Notes. In the event of future downgrades, the coupons for this series of notes are capped at 6.05% and 6.95%, respectively. The first coupon payment to the bondholders at the higher interest rates was paid in January 2017. S&P and Moody’s upgraded the Notes in April and May 2018, respectively. As a result of these upgrades, interest rates decreased to 5.30% for the 2020 Notes and 6.20% for the 2025 Notes effective July 2018. The first coupon payment to bondholders at the lower interest rates will be paid in January 2019. During the first half of 2017, the Company redeemed or repurchased (i) the remaining $38 million principal amount of its outstanding 3.30% Senior Notes due 2018, (ii) the remaining $212 million principal amount of its outstanding 7.50% Senior Notes due February 2018 and (iii) the remaining $26 million principal amount of its outstanding 7.15% Senior Notes due June 2018, and recognized an $11 million loss on the extinguishment of debt. In September 2017, the Company completed a public offering of $650 million aggregate principal amount of its 7.50% Senior Notes due 2026 (the “2026 Notes”) and $500 million aggregate principal amount of its 7.75% Senior Notes due 2027 (the “2027 Notes”), with net proceeds from the offering totaling approximately $1.1 billion after underwriting discounts and offering expenses. Both series of senior notes were sold to the public at face value. The proceeds from this offering were used to purchase $758 million of the 2020 Notes in a tender offer and to repay the outstanding balance of $327 million on the 2015 term loan. The Company recognized a loss on extinguishment of debt of $59 million, which included $53 million of premiums paid. As discussed in Note 3 above, in December 2018, the Company closed on the Fayetteville Shale sale and used a portion of the proceeds to repurchase $40 million of its 4.05% Senior Notes due January 2020, $787 million of its 4.10% Senior SWN 119 FINAL GLOSSY v6 - 4000dpi Double.pdf 103 3/25/19 5:17 PM Notes due March 2022 and $73 million of its 4.95% Senior Notes due January 2025. The Company recognized a loss on extinguishment of debt of $9 million, which included $2 million of premiums paid. (9) COMMITMENTS AND CONTINGENCIES Operating Commitments and Contingencies As of December 31, 2018, the Company’s contractual obligations for demand and similar charges under firm transportation and gathering agreements to guarantee access capacity on natural gas and liquids pipelines and gathering systems totaled approximately $8.8 billion, $3.1 billion of which related to access capacity on future pipeline and gathering infrastructure projects that still require the granting of regulatory approvals and additional construction efforts. The Company also had guarantee obligations of up to $463 million of that amount. As of December 31, 2018, future payments under non- cancelable firm transportation and gathering agreements are as follows: (in millions) Infrastructure currently in service Pending regulatory approval and/or construction (1) Total transportation charges Payments Due by Period Total Less than 1 Year 1 to 3 Years 3 to 5 Years 5 to 8 Years More than 8 Years $ $ 5,715 $ 3,079 8,794 $ 637 $ 136 773 $ 1,060 $ 348 1,408 $ 876 $ 392 1,268 $ 1,123 $ 621 1,744 $ 2,019 1,582 3,601 (1) Based on the estimated in-service dates as of December 31, 2018. In December 2018, the Company closed on the Fayetteville Shale sale. The Company retained certain contractual commitments related to firm transportation, with the buyer obligated to pay the transportation provider directly for these charges. As of December 31, 2018, approximately $221 million of these contractual commitments remain of which the Company will reimburse the buyer for certain of these potential obligations up to approximately $102 million through 2020 depending on the buyer’s actual use, and has recorded an $88 million liability for the estimated future payments. The buyer will also assume future asset retirement obligations related to the operations sold. The Company leases pressure pumping equipment for its E&P operations under a single lease that expires in 2021. The current aggregate annual payment under this lease is approximately $7 million. The Company has seven leases for drilling rigs for its E&P operations that expire through 2024 with a current aggregate annual payment of approximately $13 million. The lease payments for the pressure pumping equipment, as well as other operating expenses for the Company’s drilling operations, are capitalized to natural gas and oil properties and are partially offset by billings to third-party working interest owners. The Company leases compressors, aircraft, vehicles, office space and equipment under non-cancelable operating leases expiring through 2028. As of December 31, 2018, future minimum payments under these non-cancelable leases accounted for as operating leases are approximately $38 million in 2019, $28 million in 2020, $14 million in 2021, $6 million in 2022, $5 million in 2023 and $4 million thereafter. The Company also has commitments for compression services and rentals related to its E&P segment. As of December 31, 2018, future minimum payments under these non-cancelable agreements are approximately $3 million in 2019 and $1 million in each of 2020 and 2021. Subsequent to December 31, 2018, the Company agreed to purchase firm transportation with pipelines in the Appalachian Basin starting in 2021 and running through 2032 totaling $357 million in total contractual commitments of which the seller has agreed to reimburse $133 million of this commitment. Environmental Risk The Company is subject to laws and regulations relating to the protection of the environment. Environmental and cleanup related costs of a non-capital nature are accrued when it is both probable that a liability has been incurred and when the amount can be reasonably estimated. Management believes any future remediation or other compliance related costs will not have a material effect on the financial position, results of operations or cash flows of the Company. SWN 120 FINAL GLOSSY v6 - 4000dpi Double.pdf 104 3/25/19 5:17 PM Litigation The Company is subject to various litigation, claims and proceedings that have arisen in the ordinary course of business, such as for alleged breaches of contract, miscalculation of royalties, employment matters, traffic accidents, pollution, contamination, encroachment on others’ property or nuisance. The Company accrues for such items when a liability is both probable and the amount can be reasonably estimated. It is not possible at this time to estimate the amount of any additional loss, or range of loss that is reasonably possible, but based on the nature of the claims, management believes that current litigation, claims and proceedings, individually or in aggregate and after taking into account insurance, are not likely to have a material adverse impact on the Company’s financial position, results of operations or cash flows, for the period in which the effect of that outcome becomes reasonably estimable. Many of these matters are in early stages, so the allegations and the damage theories have not been fully developed, and are all subject to inherent uncertainties; therefore, management’s view may change in the future. Arkansas Royalty Litigation The Company has been a defendant in three certified class actions alleging that the Company underpaid lessors of lands in Arkansas by deducting from royalty payments costs for gathering, transportation and compression of natural gas in excess of what is permitted by the relevant leases. Two of these class actions were filed in Arkansas state courts and the third in the United States District court for the Eastern District of Arkansas. The Company denied liability in all three cases. Under the agreement for the sale of the Company’s properties in the Fayetteville Shale, the Company retained responsibility for these class actions. In June 2017, the jury returned a verdict in favor of the Company on all counts in Smith v. SEECO, Inc. et al., the class action in the federal court, whose plaintiff class comprises the vast majority of the lessors in these cases. The plaintiff had asserted claims for, among other things, breach of contract, fraud, civil conspiracy, unjust enrichment and violation of certain Arkansas statutes. Following the verdict, the court entered judgment in favor of the Company on all claims. The trial court denied the plaintiff’s motion for a new trial, and the plaintiff appealed to the United States Court of Appeals for the Eighth Circuit. Independent of the plaintiff’s appeal, several different parties sought to intervene in the Smith case prior to or shortly after trial, and have appealed the trial court’s order denying their request to intervene. Oral argument occurred in January 2019. The Court of Appeals has not yet issued its decision. In the second quarter of 2018, the company entered into an agreement to settle another of the class actions, which has been pending in the Circuit Court of Conway County, Arkansas under the caption Snow, et al v. SEECO, Inc., et al. The settlement received final approval by the court during the third quarter, and the deadline to appeal the order approving the settlement passed without any appeals filed. The amount of the settlement is reflected in the Company’s consolidated statement of operations for 2018 and has been paid. The third class action was dismissed in the second quarter of 2018. The Smith and the Snow cases cover all affected lessors, except a small percentage who opted out. Most of these have filed separate actions. The Company does not expect those cases to have a material adverse effect on the results of operations, financial position or cash flows of the Company. Additionally, it is not possible at this time to estimate the amount of any additional loss, or range of loss, that is reasonably possible. Indemnifications The Company provides certain indemnifications in relation to dispositions of assets. These indemnifications typically relate to disputes, litigation or tax matters existing at the date of disposition. The Company likewise obtains indemnification for future matters when it sells assets, although there is no assurance the buyer will be capable of performing those obligations. No material liabilities have been recognized in connection with these indemnifications.

The Company’s effective tax rate increased in 2018, as compared with 2017, primarily due to state income taxes resulting from the Fayetteville Shale sale and the impact of the Tax Cuts and Jobs Act (“Tax Reform Act”) on the tax rate and alternative minimum taxes, as well as changes to the overall valuation allowance activity during 2018. The following reconciles the provision for income taxes included in the consolidated statements of operations with the provision which would result from application of the statutory federal tax rate to pre-tax financial income: (in millions) Expected provision (benefit) at federal statutory rate Increase (decrease) resulting from: State income taxes, net of federal income tax effect Rate impacts due to tax reform Changes to valuation allowance due to tax reform AMT tax reform impact – valuation allowance release Changes in uncertain tax positions Change in valuation allowance Removal of sequestration fee on AMT receivables Other Provision (benefit) for income taxes 2018 2017 2016 $ 113 $ 333 $ (935) 13 – – – – (121) (5) 1 1 $ 16 370 (370) (68) (5) (364) – (5) (93) $ (79) – – – (19) 1,002 – 2 (29) $ The 2018 tax accrual calculated under the estimated annual effective tax rate method reflects the Tax Reform Act changes that took effect January 1, 2018. The components of the Company’s deferred tax balances as of December 31, 2018 and 2017 were as follows: 2018 2017 226 12 2 240 33 10 15 777 14 849 (609) – $ $ 395 19 1 415 29 14 41 1,043 20 1,147 (732) – $ $ (in millions) Deferred tax liabilities: Differences between book and tax basis of property Derivative activity Other Deferred tax assets: Accrued compensation Accrued pension costs Asset retirement obligations Net operating loss carryforward Other Valuation allowance Net deferred tax liability SWN 122 FINAL GLOSSY v6 - 4000dpi Double.pdf 106 3/25/19 5:17 PM On December 22, 2017, the United States enacted the Tax Reform Act, which made significant changes to the U.S. federal income tax law affecting the Company. Major changes in this legislation applicable to the Company relate to the reduction in the corporate tax rate to 21%, repeal of the alternative minimum tax, interest deductibility and net operating loss carryforward limitations, changes to certain executive compensation and full expensing provisions related to business assets. Due to the tax valuation allowance currently in place, any adjustments required to deferred taxes as a result of the Tax Reform Act were fully offset by valuation allowance adjustments, and the Company continues to examine the impact of this legislation and future regulations. As the Tax Reform Act repealed the corporate alternative minimum tax for tax years beginning on or after January 1, 2018 and provided for existing alternative minimum tax credit carryovers to be refunded beginning in 2018, the Company has approximately $68 million in refundable credits that are expected to be fully refunded between 2019 and 2021. Accordingly, in 2017 the valuation allowance in place prior to the Tax Reform Act related to these credits was released, and any credits remaining were reclassed to a receivable. In February 2018, the FASB issued Accounting Standards Update No. 2018-02 (“Update 2018-02”) amending the FASB Accounting Standards relating to tax effects in accumulated other comprehensive income. In the first quarter of 2018, the Company elected to early adopt the amendments of Update 2018-02. The implementation did not have a material impact on the Company’s consolidated statements of operations, financial position or cash flows due to the tax valuation allowance currently in place. See Note 1 for more information regarding this update. In 2018, the Company made state income tax payments of $6.3 million. In 2017, the Company received less than $1 million in state income tax refunds and received $4.2 million in federal income tax refunds. The Company’s net operating loss carryforward as of December 31, 2018 was $3.0 billion and $2.1 billion for federal and state reporting purposes, respectively, the majority of which will expire between 2035 and 2037. Additionally, the Company has an income tax net operating loss carryforward related to its Canadian operations of $29 million, with expiration dates of 2030 through 2038. The Company also had a statutory depletion carryforward of $13 million as of December 31, 2018. A valuation allowance for deferred tax assets, including net operating losses, is recognized when it is more likely than not that some or all of the benefit from the deferred tax asset will not be realized. To assess the likelihood, the Company uses estimates and judgment regarding future taxable income, and considers the tax consequences in the jurisdiction where such taxable income is generated, to determine whether a valuation allowance is required. Such evidence can include current financial position, results of operations, both actual and forecasted, the reversal of deferred tax liabilities, and tax planning strategies as well as current and forecasted business economics of the oil and gas industry. The Company maintained its net deferred tax asset position at December 31, 2018 primarily due to the prior write-downs of the carrying value of natural gas and oil properties. The Company believes it is more likely than not that these deferred tax assets will not be realized and accordingly maintained our full valuation allowance to adjust the remaining deferred tax asset to zero for the year ended December 31, 2018. During 2018, the valuation allowance was reduced $123 million, $121 million as a component of income tax expense and $2 million as a reduction of equity. Management assesses available positive and negative evidence to estimate whether sufficient future taxable income will be generated to permit the use of deferred tax assets. In management’s view, the cumulative loss incurred over the three-year period ending December 31, 2018, outweighs any positive factors, such as the possibility of future growth. The amount of the deferred tax asset considered realizable, however, could be adjusted if estimates of future taxable income are increased or if objective negative evidence in the form of cumulative losses is no longer present and additional weight is given to subjective evidence such as future expected growth. It is reasonably possible that a release of the valuation allowance could occur as early as the first quarter of 2019 if the Company moves into a three-year pre-tax income position combined with other positive evidence of future taxable income. A reconciliation of the changes to the valuation allowance is as follows: (in millions) Valuation allowance as of December 31, 2017 Changes based on 2018 activity Equity – pension benefits in OCI Valuation allowance as of December 31, 2018 $ $ 732 (121) (2) 609 On March 30, 2016, the FASB modified its accounting policy on share‐based payments (ASU 2016-09). Updates included tax impacts related to the treatment of excess tax benefits (“windfalls”) and deficiencies (“shortfalls”) were made and became effective on January 1, 2017. The Company had previously unrecognized tax “windfall” benefits of $149 million as of December 31, 2016, which were released in the first quarter of 2017. The recognition of previously unrecognized SWN 123 FINAL GLOSSY v6 - 4000dpi Double.pdf 107 3/25/19 5:17 PM windfall tax benefits resulted in a net cumulative-effect adjustment of $59 million, which increased net deferred tax assets and the related income tax valuation allowance by the same amount as of the beginning of 2017. As of December 31, 2018, no unrecognized tax benefits exist related to share-based payments. A tax position must meet certain thresholds for any of the benefit of the uncertain tax position to be recognized in the financial statements. As of December 31, 2018, the amount of unrecognized tax benefits related to alternative minimum tax was $7 million. The uncertain tax position identified would not have a material effect on the effective tax rate. No material changes to the current uncertain tax position are expected within the next 12 months. As of December 31, 2018, the Company had accrued a liability of less than $1 million of interest related to this uncertain tax position. The Company recognizes penalties and interest related to uncertain tax positions in income tax expense.

(12) RETIREMENT AND EMPLOYEE BENEFIT PLANS 401(k) Defined Contribution Plan The Company has a 401(k) defined contribution plan covering eligible employees. The Company expensed $3 million, $3 million and $4 million of contribution expense in 2018, 2017 and 2016, respectively. Additionally, the Company capitalized $2 million of contributions in each of 2018, 2017 and 2016, directly related to the acquisition, exploration and development activities of the Company’s natural gas and oil properties or directly related to the construction of the Company’s gathering systems. Defined Benefit Pension and Other Postretirement Plans Prior to January 1, 1998, the Company maintained a traditional defined benefit plan with benefits payable based upon average final compensation and years of service. Effective January 1, 1998, the Company amended its pension plan to become a “cash balance” plan on a prospective basis for its non-bargaining employees. A cash balance plan provides benefits based upon a fixed percentage of an employee’s annual compensation. The Company’s funding policy is to contribute amounts which are actuarially determined to provide the plans with sufficient assets to meet future benefit payment requirements and which are tax deductible. SWN 124 FINAL GLOSSY v6 - 4000dpi Double.pdf 108 3/25/19 5:17 PM The postretirement benefit plan provides contributory health care and life insurance benefits. Employees become eligible for these benefits if they meet age and service requirements. Generally, the benefits paid are a stated percentage of medical expenses reduced by deductibles and other coverages. Substantially all of the Company’s employees are covered by the defined benefit pension and postretirement benefit plans. The Company accounts for its defined benefit pension and other postretirement plans by recognizing the funded status of each defined pension benefit plan and other postretirement benefit plan on the Company’s balance sheet. In the event a plan is overfunded, the Company recognizes an asset. Conversely, if a plan is underfunded, the Company recognizes a liability. In June 2018, the Company notified affected employees of a workforce reduction plan, which resulted primarily from a previously announced study of structural, process and organizational changes to enhance shareholder value and continues with respect to other aspects of the Company’s business activities. In December 2018, the Company closed on the sale of the equity in certain of its subsidiaries that owned and operated its Fayetteville Shale E&P and related midstream gathering assets in Arkansas. As part of this transaction, many employees associated with those assets were either transferred to the buyer or their employment was terminated. As a result of the restructurings, the Company recognized a curtailment on its pension and other postretirement benefit plans and recognized a non-cash gain of $4 million on its consolidated statements of operations. During the first half of 2019, the Company will recognize settlements related to these restructuring events, and the amounts may be material. In January 2016, the Company initiated a reduction in workforce that was effectively completed by the end of the first quarter. As a result of the workforce reduction, the Company recognized a $1 million non-cash curtailment loss related to its pension plan for both the curtailment-related decrease to the benefit obligation and the recognition of the proportionate share of unrecognized prior service cost and net loss from other comprehensive income (loss) in the second quarter of 2016. For the year ended December 31, 2016, the Company recognized a non-cash settlement loss of $11 million related to a total of $37 million of lump sum payments from the pension plan. Additionally, the Company recognized a non-cash curtailment gain of $6 million related to its other postretirement benefit plan in the first quarter of 2016. The following provides a reconciliation of the changes in the plans’ benefit obligations, fair value of assets and funded status as of December 31, 2018 and 2017: (in millions) Change in benefit obligations: Benefit obligation at January 1 Service cost Interest cost Participant contributions Actuarial loss (gain) Benefits paid Plan amendments Curtailments Benefit obligation at December 31 (in millions) Change in plan assets: Fair value of plan assets at January 1 Actual return on plan assets Employer contributions Participant contributions Benefits paid Fair value of plan assets at December 31 Funded status of plans at December 31 Pension Benefits 2018 2017 Other Postretirement Benefits 2018 2017 $ $ $ $ $ 143 $ 10 5 – (14) (14) – (5) 125 $ Pension Benefits 2018 2017 101 $ (8) 12 – (14) 91 $ 117 $ 9 5 – 21 (9) – – 143 $ 81 $ 15 14 – (9) 101 $ 17 $ 2 1 – − (1) – (6) 13 $ Other Postretirement Benefits 2018 2017 – $ – 1 – (1) – $ 13 2 – – 3 (1) – – 17 – – 1 – (1) – (34) $ (42) $ (13) $ (17) The Company uses a December 31 measurement date for all of its plans and had liabilities recorded for the underfunded status for each period as presented above.

For the year ended December 31, 2018, $6 million was classified to accumulated other comprehensive income, primarily driven by actuarial gain adjustments. Amortization of prior period service cost reclassified from accumulated other comprehensive income to general and administrative expenses for the year was immaterial. The amount in accumulated other comprehensive income that is expected to be recognized as a component of net periodic benefit cost during 2019 is a $2 million net loss.

The plans seek to achieve an adequate return to fund the obligations in a manner consistent with the federal standards of the Employee Retirement Income Security Act and with a prudent level of diversification. For measurement purposes, the following trend rates were assumed for 2018 and 2017: Health care cost trend assumed for next year Rate to which the cost trend is assumed to decline Year that the rate reaches the ultimate trend rate 2018 2017 7% 5% 2036 7% 5% 2035 Assumed health care cost trend rates have a significant effect on the amounts for the health care plans.

The Benefits Administration Committee of the Company, appointed by the Compensation Committee of the Board of Directors, administers the Company’s pension plan assets. The Benefits Administration Committee believes long-term investment performance is a function of asset-class mix and restricts the composition of pension plan assets to a combination of cash and cash equivalents, domestic equity markets, international equity markets or investment grade fixed income assets.

The Company’s pension plan assets that are classified as Level 1 are the investments comprised of either cash or investments in open-ended mutual funds which produce a daily net asset value that is validated with a sufficient level of observable activity to support classification of the fair value measurement as Level 1. Due to the Company’s implementation of Accounting Standards Update No. 2015-07, assets measured using net asset value as a practical expedient have not been classified in the fair value hierarchy. No concentration of risk arising within or across categories of plan assets exists due to any significant investments in a single entity, industry, country or investment fund. (13) STOCK-BASED COMPENSATION The Southwestern Energy Company 2013 Incentive Plan was adopted in February 2013, approved by stockholders in May 2013 and amended and restated per stockholders’ approval in May 2016 and further amended in May 2017 (the “2013 Plan”). The 2013 Plan provides for the compensation of officers, key employees and eligible non-employee directors of the Company and its subsidiaries. The 2013 Plan provides for grants of options, stock appreciation rights, and shares of restricted stock and restricted stock units to employees, officers and directors that, in the aggregate, do not exceed 52,700,000 shares. The types of incentives that may be awarded are comprehensive and are intended to enable the Company’s Board of Directors to structure the most appropriate incentives and to address changes in income tax laws which may be enacted over the term of the 2013 Plan.

The fair value of an equity-classified award is determined at the grant date and is amortized to general and administrative expense on a straight-line basis over the vesting period of the award. The fair value of a liability- classified award is determined on a quarterly basis beginning at the grant date until final vesting. Changes in the fair value of liability-classified awards are recorded to general and administrative expense over the vesting period of the award. A portion of this general and administrative expense is capitalized into natural gas and oil properties, included in property and equipment. Generally, stock options granted to employees and directors vest ratably over three years from the grant date and expire seven years from the date of grant. The Company issues shares of restricted stock or restricted stock units to employees and directors which generally vest over four years. Restricted stock, restricted stock units and stock options granted to participants under the 2013 Plan immediately vest upon death, disability or retirement (subject to a minimum of three years of service). In June 2018, the Company announced a workforce reduction. Unvested stock-based awards of the affected employees were subsequently cancelled and the approximate fair value of a portion of those cancelled awards was included in a cash severance payment that was paid in the third quarter of 2018. Stock-based compensation costs recognized prior to the cancellation as either general and administrative expense or capitalized expense were reversed and the severance payments were subsequently recognized as restructuring charges for the year ended December 31, 2018 on the consolidated statements of operations. In December 2018, the Company closed on the sale of the equity in certain of its subsidiaries that owned and operated its Fayetteville Shale E&P and related midstream gathering assets in Arkansas. As part of this transaction, most employees associated with those assets became employees of the buyer although the employment of some was or will be terminated. All affected employees were offered a severance package, which included a one-time cash payment depending on length of service and, if applicable, the current value of a portion of equity awards that were forfeited. Stock-based compensation costs recognized prior to the cancellation as either general and administrative expense or capitalized expense were reversed and the severance payments were subsequently recognized as restructuring charges for the year ended December 31, 2018 on the consolidated statements of operations. In January 2016, the Company announced a 40% workforce reduction that was substantially concluded by the end of March 2016. In April 2016, the Company also partially restructured executive management, which was substantially completed in the second quarter of 2016. Affected employees were offered a severance package that included, if applicable, amendments to certain outstanding equity awards that modified forfeiture provisions upon separation from the Company. As a result, certain unvested stock-based equity awards became fully vested at the time of separation. These shares were revalued and recognized immediately as a component of restructuring charges on the Company’s consolidated statement of operations. The unvested portion of equity-based performance units was cancelled upon separation from the Company. Equity-Classified Awards Equity-Classified Stock Options The Company recorded the following compensation costs related to stock options for the years ended December 31, 2018, 2017 and 2016: (in millions) Stock options – general and administrative expense (1) Stock options – general and administrative expense capitalized 2018 2017 2016 $ $ 2 – $ $ 3 $ 1 $ 6 1 (1) Includes less than $1 million related to the reduction in workforce and $1 million related to executive management restructuring for the year ended December 31, 2016.

Expected volatility is based on historical volatility of the Company’s common stock and other factors. The Company uses historical data on the exercise of stock options, post-vesting forfeitures and other factors to estimate the expected term of the stock-based payments granted.

Revenues for the E&P segment are derived from the production and sale of natural gas and liquids. The Midstream segment generates revenue through the marketing of both Company and third-party produced natural gas and liquids volumes. Prior to December 2018, the Midstream segment included the Company’s natural gas gathering business associated with its Fayetteville Shale assets. With the closing of the Fayetteville Shale sale in December 2018, the Midstream segment consists almost entirely of the Company’s marketing business. Summarized financial information for the Company’s reportable segments is shown in the following table. The accounting policies of the segments are the same as those described in Note 1. Management evaluates the performance of its segments based on operating income, defined as operating revenues less operating costs. Income before income taxes, for the purpose of reconciling the operating income amount shown below to consolidated income before income taxes, is the sum of operating income, interest expense, gain (loss) on derivatives, loss on early extinguishment of debt and other income (loss). The “Other” column includes items not related to the Company’s reportable segments, including real estate and corporate items.

Pursuant to requirements under the indentures governing the Company’s senior notes, each 100% owned subsidiary that became a guarantor of the 2018 credit facility also became a guarantor of each of the Company’s senior notes (the “Guarantor Subsidiaries”). The Guarantor Subsidiaries also granted liens and security interests to support their guarantees under the 2018 credit facility but not of the senior notes. These guarantees are full and unconditional and joint and several among the Guarantor Subsidiaries. Certain of the Company’s subsidiaries which are accounted for on a consolidated basis do not guarantee the 2018 credit facility and senior notes (“Non- Guarantor Subsidiaries”). See Note 8 for additional information on the Company’s 2018 revolving credit facility and senior notes. At the closing of the Fayetteville Shale sale in December 2018, the Company’s subsidiaries being sold were released from these guarantees. See Note 3 for additional information on the divestiture of the Company’s Fayetteville Shale-related subsidiaries. The following financial information reflects consolidating financial information of Southwestern Energy Company (the parent and issuer company), its Guarantor Subsidiaries on a combined basis and the Non-Guarantor Subsidiaries on a combined basis, prepared on the equity basis of accounting. The information is presented in accordance with the requirements of Rule 3-10 under the SEC’s Regulation S-X. The financial information may not necessarily be indicative of results of operations, cash flows or financial position had the Guarantor Subsidiaries operated as independent entities.

The Company also has licenses to properties in Canada, the development of which is subject to an indefinite moratorium. See “Our Operations – Other – New Brunswick, Canada” in Item 1 of Part 1 of this Annual Report. Net Capitalized Costs The following table shows the capitalized costs of natural gas and oil properties and the related accumulated depreciation, depletion and amortization as of December 31, 2018 and 2017: (in millions) Proved properties Unproved properties Total capitalized costs Less: Accumulated depreciation, depletion and amortization Net capitalized costs 2018 2017 22,425 1,755 24,180 (19,761) 4,419 $ $ 22,073 1,817 23,890 (19,287) 4,603 $ $ Natural gas and oil properties not subject to amortization represent investments in unproved properties and major development projects in which the Company owns an interest. These unproved property costs include unevaluated costs associated with leasehold or drilling interests and unevaluated costs associated with wells in progress. The table below sets forth the composition of net unevaluated costs excluded from amortization as of December 31, 2018: (in millions) Property acquisition costs Exploration and development costs Capitalized interest 2018 2017 2016 Prior Total $ $ 49 $ 42 77 168 $ 70 $ 23 45 138 $ 12 $ 6 28 46 $ 1,346 $ 23 34 1,403 $ 1,477 94 184 1,755 Of the total net unevaluated costs excluded from amortization as of December 31, 2018, approximately $1.5 billion is related to undeveloped properties in Southwest Appalachia (acquired in 2014), approximately $23 million is related to the acquisition of the Company’s undeveloped properties in Northeast Appalachia and approximately $11 million is related to the acquisition of undeveloped properties outside the Appalachian Basin. Additionally, the Company has approximately $184 million of unevaluated capitalized interest and $77 million of unevaluated costs related to wells in progress. The remaining costs excluded from amortization are related to properties which are not individually significant and on which the evaluation process has not been completed. The timing and amount of property acquisition and seismic costs included in the amortization computation will depend on the location and timing of drilling wells, results of drilling and other assessments. The Company is, therefore, unable to estimate when these costs will be included in the amortization computation.

The Company capitalized $115 million, $113 million and $152 million during 2018, 2017 and 2016, respectively, based on the Company’s weighted average cost of borrowings used to finance expenditures. In addition to capitalized interest, the Company capitalized internal costs totaling $90 million, $99 million and $87 million during 2018, 2017 and 2016, respectively, which were directly related to the acquisition, exploration and development of the Company’s natural gas and oil properties. Results of Operations from Natural Gas and Oil Producing Activities The table below sets forth the results of operations from natural gas and oil producing activities: (in millions) Sales Production (lifting) costs Depreciation, depletion and amortization Impairment of natural gas and oil properties Provision (benefit) for income taxes (1) Results of operations (2) 2018 2017 2016 $ $ 2,525 $ (974) (514) – 1,037 – 1,037 $ 2,086 $ (891) (440) – 755 – 755 $ 1,413 (839) (371) (2,321) (2,118) – (2,118) (1) Prior to the recognition of a valuation allowance, in 2018, 2017 and 2016 the Company recognized income tax provisions of $254 million, $287 million and $805 million, respectively. (2) Results of operations exclude the gain (loss) on unsettled commodity derivative instruments. See Note 5 – “Derivatives and Risk Management”. The results of operations shown above exclude general and administrative expenses and interest expense and are not necessarily indicative of the contribution made by the Company’s natural gas and oil operations to its consolidated operating results. Income tax expense is calculated by applying the statutory tax rates to the revenues less costs, including depreciation, depletion and amortization, and after giving effect to permanent differences and tax credits. Natural Gas and Oil Reserve Quantities The Company engaged the services of Netherland, Sewell & Associates, Inc., or NSAI, an independent petroleum engineering firm, to audit the reserves estimated by the Company’s reservoir engineers. In conducting its audit, the engineers and geologists of NSAI studied the Company’s major properties in detail and independently developed reserve estimates. NSAI’s audit consists primarily of substantive testing, which includes a detailed review of the Company’s major properties, and accounted for approximately 99% of the present worth of the Company’s total proved reserves as of December 31 of 2018, 2017 and 2016. A reserve audit is not the same as a financial audit, and a reserve audit is less rigorous in nature than a reserve report prepared by an independent petroleum engineering firm containing its own estimate of reserves. Reserve estimates are inherently imprecise, and the Company’s reserve estimates are generally based upon extrapolation of historical production trends, historical prices of natural gas and crude oil and analogy to similar properties and volumetric calculations. Accordingly, the Company’s estimates are expected to change, and such changes could be material and occur in the near term as future information becomes available. For more information over reserves, refer to the table titled “Changes in Proved Undeveloped Reserves (Bcfe)” in “Business – Exploration and Production” in Item 1 of this Annual Report.

The Company’s reserves decreased in 2018, compared to 2017, as the disposition of the reserves related to the Fayetteville Shale was only partially offset by positive extensions, discoveries, other additions and revisions in the Appalachian Basin. The increase in the Company's reserves in 2017 primarily resulted through extensions, discoveries and other additions in the Appalachian Basin along with increases in both price and performance revisions across the portfolio. The decrease in the Company's reserves in 2016 was primarily due to the decrease in commodity prices.

The Company used standard engineering and geoscience methods, or a combination of methodologies in determining estimates of material properties, including performance and test date analysis, offset statistical analogy of performance data, volumetric evaluation, including analysis of petrophysical parameters (including porosity, net pay, fluid saturations (i.e., water, oil and gas) and permeability) in combination with estimated reservoir parameters (including reservoir temperature and pressure, formation depth and formation volume factors), geological analysis, including structure and isopach maps and seismic analysis, including review of 2-D and 3-D data to ascertain faults, closure and other factors. Standardized Measure of Discounted Future Net Cash Flows The following standardized measures of discounted future net cash flows relating to proved natural gas, oil and NGL reserves as of December 31, 2018, 2017 and 2016 are calculated after income taxes, discounted using a 10% annual discount rate and do not purport to present the fair market value of the Company’s proved gas, oil and NGL reserves: (in millions) Future cash inflows Future production costs Future development costs (1) Future income tax expense (2) Future net cash flows 10% annual discount for estimated timing of cash flows Standardized measure of discounted future net cash flows (1) Includes abandonment costs. 2018 2017 2016 $ $ 34,523 $ (15,347) (4,095) (2,079) 13,002 (7,003) 5,999 $ 36,576 $ (18,390) (4,676) (1,342) 12,168 (6,606) 5,562 $ 9,064 (5,880) (485) – 2,699 (1,034) 1,665 (2) The December 31, 2016 standardized measure computation does not have future income taxes because the Company’s tax basis in the associated oil and gas properties exceeded expected pre-tax cash inflows. Future net cash flows are not permitted to be increased by excess tax basis. Under the standardized measure, future cash inflows were estimated by applying an average price from the first day of each month from the previous 12 months, adjusted for known contractual changes, to the estimated future production of year- end proved reserves. Prices used for the standardized measure above were as follows: (in millions) Natural gas (per MMBtu) Oil (per Bbl) NGLs (per Bbl) $ 2018 2017 2016 3.10 $ 65.56 17.64 2.98 $ 47.79 14.41 2.48 39.25 6.74 Future cash inflows were reduced by estimated future production and development costs based on year-end costs to determine pre-tax cash inflows. Future income taxes were computed by applying the year-end statutory rate to the excess of pre-tax cash inflows over the Company’s tax basis in the associated proved gas and oil properties after giving effect to permanent differences and tax credits. Following is an analysis of changes in the standardized measure during 2018, 2017 and 2016: (in millions) Standardized measure, beginning of year Sales and transfers of natural gas and oil produced, net of production costs Net changes in prices and production costs Extensions, discoveries, and other additions, net of future production and development costs Acquisition of reserves in place Sales of reserves in place Revisions of previous quantity estimates Net change in income taxes Changes in estimated future development costs Previously estimated development costs incurred during the year Changes in production rates (timing) and other Accretion of discount Standardized measure, end of year $ $ 2018 2017 2016 5,562 (1,564) 2,162 335 – (2,022) 361 (304) (166) 536 521 578 5,999 $ $ $ 1,665 (1,191) 1,963 1,715 – – 1,721 (222) (6) 55 (304) 166 5,562 $ 2,417 (574) (415) 45 – (10) (140) – 71 114 (85) 242 1,665 SWN 147 FINAL GLOSSY v6 - 4000dpi Double.pdf 131 3/25/19 5:17 PM ITEM 9. CHANGES IN AND DISAGREEMENTS WITH ACCOUNTANTS ON ACCOUNTING AND FINANCIAL DISCLOSURE None. ITEM 9A. CONTROLS AND PROCEDURES Disclosure Controls and Procedures We have performed an evaluation under the supervision and with the participation of our management, including our Chief Executive Officer and Chief Financial Officer, of the effectiveness of our disclosure controls and procedures, as defined in Rule 13a-15(e) and 15d-15(e) under the Exchange Act. Our disclosure controls and procedures are the controls and other procedures that we have designed to ensure that we record, process, accumulate and communicate information to our management, including our Chief Executive Officer and Chief Financial Officer, to allow timely decisions regarding required disclosures and submission within the time periods specified in the SEC’s rules and forms. All internal control systems, no matter how well designed, have inherent limitations. Therefore, even those determined to be effective can provide only a level of reasonable assurance with respect to financial statement preparation and presentation. Based on the evaluation, our management, including our Chief Executive Officer and Chief Financial Officer, concluded that our disclosure controls and procedures were effective as of December 31, 2018 at a reasonable assurance level. There were no changes in our internal control over financial reporting (as defined in Rule 13a-15(f) and 15d-15(f) under the Exchange Act) that occurred during the quarter ended December 31, 2018, that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting. Management’s Report on Internal Control Over Financial Reporting is included on page 89 of this Annual Report. PricewaterhouseCoopers LLP’s report on Southwestern Energy’s internal control over financial reporting is included in its Report of Independent Registered Public Accounting Firm on page 89 of this Annual Report. ITEM 9B. OTHER INFORMATION On February 25, 2019, the Compensation Committee of the Board of Directors of Southwestern Energy Company (the “Company”) granted, subject to the approval of the Board, long-term incentives under the Company’s 2013 Incentive Plan, as amended (the “Plan”), to its principal executive officer, principal financial officer and other named executive officers. On February 26, 2019, the Company’s Board approved these grants. The grants were comprised of two types of awards, the principal features of which are: Restricted Stock Units. Each restricted stock unit that vests will entitle the holder to receive, at the Compensation Committee’s option, either one share of common stock of the Company or a cash amount equal to the closing price of the Company’s common stock on the vesting date. 25% of the restricted stock units vest on each of the first through the fourth anniversaries of the date of grant, provided the grantee is still an employee of the Company on the vesting date; however, all restricted stock units vest in the case of the grantee’s Retirement, death or Disability or on a Change in Control, as defined in the Plan. Performance Units. Each performance unit that vests will entitle the holder to receive a value of 0 to 2 shares of common stock of the Company depending on the Company’s performance regarding specified metrics over the years 2019-2021, payable at the Compensation Committee’s discretion either in shares of the Company’s common stock or a cash amount equal to the closing price of the Company’s common stock on the vesting date. The vesting date is the third anniversary of the date of grant, provided the grantee is still an employee of the Company on the vesting date; however, a pro rata portion of performance units vest in the case of the grantee’s Retirement, death or Disability, as defined in the Plan, and on a Change in Control, as defined in the Plan, the award vests at the greater of target value and the projected value as if the performance period had been completed (without pro ration). The determination of the value of each unit from 0 to 2 shares of common stock of the Company is based on the achievement of threshold, target or maximum goals on the following metrics over a three-year performance period, being the calendar years 2019-2021: • 50% Relative Total Shareholder Return – the difference between (a) the average of the closing prices for the Company’s common stock on the last 20 trading days of 2021 plus all dividends paid on account of one share of the Company’s common stock and (b) the average of the closing prices for the last 20 trading days of 2018, as compared to the same calculation for a specified group of the Company’s peers. SWN 148 FINAL GLOSSY v6 - 4000dpi Double.pdf 132 3/25/19 5:17 PM • • 25% Absolute Total Shareholder Return – the difference between (a) the average of the closing prices for the Company’s common stock on the last 20 trading days of 2021 plus all dividends paid on account of one share of the Company’s common stock and (b) the average of the closing prices for the last 20 trading days of 2018. 25% Return on Average Capital Employed – calculated by dividing (i) the average of net cash provided by operating activities from the Consolidated Statement of Cash Flows less “changes in assets and liabilities” included in the Operating Activities section of the Consolidated Statement of Cash Flows for the performance period by the sum of (ii) the product of the twenty-day average stock price immediately prior to the first day of the performance period and the diluted weighted average number of shares of common stock of the Company outstanding for the fourth quarter of the year prior to the beginning of the performance period, (iii) gross debt of the Company (net of cash and cash equivalents) outstanding on December 31 of the year prior to the beginning of the performance period, and (iv) the sum of (a) the product of the number of shares of common stock the Company issued during the performance period and the price of said shares and (b) the amount of additional net debt incurred during the performance period, which sum shall then be reduced by (c) the amount by which any net debt is reduced during the performance period and (d) the product of the number of shares of common stock of the company purchased by the company during the performance period and the price of said shares, with each occurrence of the above in (a) – (d) multiplied by a fraction in which the denominator equals the total number of quarters in the Performance Period (12) and the numerator equals the remaining number of quarters following each occurrence of the above in (a) – (d) plus one. For each portion, a threshold level must be achieved for any amount to be payable. Performance at target level for all three metrics will result in a payout equal to one share per unit (or its value in cash), and there is a maximum level that, if all three metrics perform at maximum, entitles the holder to two shares (or their value in cash) per unit. The Relative Total Shareholder Return portion will be deemed not to exceed the target level if the Absolute Total Shareholder Return is negative, and if the Relative Total Shareholder Return portion is less than target, the Absolute Total Shareholder Return portion will be deemed not to exceed target level performance. William J. Way, President and Chief Executive Officer, was granted 803,580 of each type of award; Julian M. Bott, Executive Vice President and Chief Financial Officer, was granted 297,620 of each type of award; J.
