First Quarter of 2018 Financial Results

Operating income was $255 million for the first quarter of 2018.  E&P segment operating income of $238 million was 6% higher than the first quarter of 2017 driven by higher production and improved realized pricing, partially offset by higher operating costs associated with increased volumes.  In the Appalachian Basin, net cash provided by operating activities increased to approximately $294 million for the first quarter of 2018, or 36%, compared to approximately $216 million during the first quarter of 2017.        

During the first quarter of 2018, production increased by 11%, including a 37% increase in liquids production, compared to the first quarter of 2017.  In the Appalachian Basin, production increased to 159 Bcfe or 1.77 Bcfe per day, an increase of 29% compared to the first quarter of 2017, despite the impact of winter weather. 

The Company’s realized natural gas price excluding derivatives was $2.72 per Mcf, comparable to the first quarter of 2017, despite a 10% decrease in NYMEX pricing.  This includes a $0.31 per Mcf improvement in the discount to NYMEX prices, driven by Northeast Appalachia where the Company realized a $0.04 per Mcf premium to NYMEX for the first quarter of 2018.  Additionally, NGL pricing, excluding derivatives, increased to $15.42 per Bbl, including C3+ pricing of $36.01 per Bbl, an increase of 16% compared to the first quarter of 2017.  The increase in liquids production and realizations generated

3

a $0.09 per Mcfe uplift to the Company’s weighted average realized price excluding derivatives compared to a $0.02 per Mcfe uplift in the same period in 2017.

Midstream operating income, comprised of gathering and marketing activities, was $17 million for the first quarter of 2018, compared to $41 million for the same period of 2017.  The change in operating income was driven by decreased gathered volumes associated with lower production and one-time compressor facility repair costs in the Fayetteville Shale and the impairment of an unrelated, non-core gathering asset. 

Capital Structure and Investments –  At March 31, 2017, the Company had cash of $958 million, gross debt of $4.4 billion and $3.4 billion in net debt.  In April 2018, the Company entered into a new, five-year $3.5 billion secured revolving credit facility, supported by an initial borrowing base of $3.2 billion, with the Company electing an initial commitment of $2.0 billion.  Pricing is based on LIBOR plus a margin of 150 to 250 basis points, depending on utilization. The new agreement is expected to reduce interest expense by approximately $20 million in 2018 and approximately $30 million annually in future years.  This facility replaces the 2016 revolving credit and secured term loan bank facilities, with the prior term loan bank facility borrowings retired using cash on hand and borrowings under the new facility.

During the first quarter of 2018, Southwestern Energy invested total capital of $338 million.  This included approximately $334 million invested in its E&P business and $4 million invested in the Midstream segment.  Of the $338 million, approximately $28 million was associated with capitalized interest and $25 million was associated with capitalized expenses.

E&P Operational Review

During the first quarter of 2018, Southwestern Energy invested a total of approximately $334 million in its E&P business, and drilled 32 wells, completed 29 wells, and placed 33 wells to sales.

(1) Southwest Appalachia production included 22 Bcf of natural gas, 4,218 MBbls of NGLs and 594 MBbls of oil.

(2) Temporarily restricted Fayetteville production rate due to compressor facility repairs.  The rate on March 31, 2018 was 1,121 MMcf/d.

(3) Southwest Appalachia includes only wells drilled and completed by SWN.

(4) This discount includes a basis differential, physical basis sales, third-party transportation charges and fuel charges and excludes financial basis hedges.

Southwest Appalachia– Southwestern Energy had total net production of 51 Bcfe, or 567 MMcfe per day, a 42% increase compared to the first quarter of 2017.  Higher liquids production and realizations continue to drive margin expansion, with the increase in liquids realizations generating a price uplift of approximately $0.53 per Mcfe compared to its realized natural gas price of $2.75 per Mcf.  Southwest Appalachia’s weighted average realized price for the first quarter improved to $3.00 per Mcfe which matched NYMEX gas price for the first quarter of 2018. 

Southwestern Energy placed 16 wells to sales, 14 of which were drilled and completed by the Company.  Twelve Company drilled and completed wells, targeting the Marcellus rich gas window, were online for at least 30 days and had an average lateral length of 6,950 feet with an average 30 day rate of approximately 8.4 MMcfe per day, comprised of 67% liquids.  These 12 wells were producing over 130 MMcfe per day including over 5,000 Bbls per day of condensate at the end of the quarter, contributing to a 27% increase in Southwest Appalachia’s quarter over quarter condensate exit rate.  The Company

5

continues to extend lateral lengths and drilled its longest well in Southwest Appalachia with a measured depth of over 20,000 feet and horizontal lateral over 13,400 feet.

Northeast Appalachia– The Company had total net production of 108 Bcf, or 1.2 Bcf per day, a 24% increase compared to the first quarter of 2017.  Northeast Appalachia realized a premium of $0.04 per Mcf to NYMEX gas price, including transportation costs, and generated positive net cash flow from operating activities, net of capital, of approximately $115 million.  The Company was able to take advantage of its firm transportation portfolio to capture increased pricing due to winter weather.

The Company placed 17 wells to sales in the first quarter, all in Susquehanna County.  The average rate for the first 30 days for the 8 wells that were online for at least 30 days was 15.2 MMcf per day per well.  In March, the Watts 1H well was placed to sales and was drilled with a lateral length of over 11,200 feet and had an initial production rate of 34.1 MMcf per day, further demonstrating improved capital efficiency that will continue to be targeted throughout the area.

The Company is driving further improvements in its Tioga area economics by lowering projected completion costs through water infrastructure installation and increasing lateral lengths.  The Company commissioned dedicated third-party water infrastructure in Tioga, expected to reduce completion costs by approximately $400,000 per well by the middle of 2018.  Additionally, the latest 3-well pad drilled in Tioga had an average lateral length of over 10,800 feet, a 45% improvement compared to historical drilled wells in this area.

Fayetteville Shale–  The Company drilled two additional wells that were placed to sales in mid-April as part of its field-wide redevelopment program, which utilizes advanced completion designs and optimized landing zones to improve well performance.  The Sisson well had a lateral length of 8,642 feet and an initial production rate of approximately 8 MMcf per day.  The Guinn James well had a lateral length of 4,944 feet and an initial production rate of approximately 6 MMcf per day. This well is currently in the early stages of flowback and is still cleaning up.  Additionally, the Company’s cumulative production from its initial redevelopment well, the McNew, is further outperforming historical production in the area by over 60% in the first 180 days online.  These well results, supported by the Company’s big data analytics, further confirm Fayetteville’s low-risk redevelopment opportunities.

Hedging Update

Southwestern Energy continues to execute a disciplined hedging program with physical, financial and basis hedges on its forecasted natural gas and natural gas liquids production.  As of April 24, 2018, the Company had approximately 434 Bcf of its remaining 2018 forecasted gas production volumes protected at an average swap or purchased put strike price of $2.97 per Mcf.  Approximately half of these protected volumes retain upside exposure up to $3.37 Mcf.  Additionally, the Company had approximately 311 Bcf of its 2019 forecasted gas production protected at an average swap or purchased put strike price of $2.92 per Mcf, with upside exposure on approximately 60%, or 186 Bcf, of those protected volumes up to $3.24 per Mcf. 

A detailed breakdown of the Company’s natural gas derivative financial instruments as of April 24, 2018 is shown below.  Please refer to our quarterly report on Form 10-Q to be filed with the Securities and Exchange Commission for complete information on the Company’s commodity, basis and interest rate protection.

Explanation and Reconciliation of Non-GAAP Financial Measures

The Company reports its financial results in accordance with accounting principles generally accepted in the United States of America (“GAAP”). However, management believes certain non-GAAP performance measures may provide financial statement users with additional meaningful comparisons between current results, the results of its peers and of prior periods.

One such non-GAAP financial measure is net cash flow. Management presents this measure because (i) it is accepted as an indicator of an oil and gas exploration and production company’s ability to internally fund exploration and development activities and to service or incur additional debt, (ii) changes in operating assets and liabilities relate to the timing of cash receipts and disbursements which the Company may not control and (iii) changes in operating assets and liabilities may not relate to the period in which the operating activities occurred.

Additional non-GAAP financial measures the Company may present from time to time are net debt, adjusted net income, adjusted diluted earnings per share, adjusted EBITDA and its E&P and Midstream segment operating income, all which exclude certain charges or amounts. Management presents these measures because (i) they are consistent with the manner in which the Company’s position and performance are measured relative to the position and performance of its peers, (ii) these measures are more comparable to earnings estimates provided by securities analysts, and (iii) charges or amounts excluded cannot be reasonably estimated and guidance provided by the Company excludes

8

information regarding these types of items. These adjusted amounts are not a measure of financial performance under GAAP.

See the reconciliations throughout this release of GAAP financial measures to non-GAAP financial measures for the three months ended March 31, 2018 and March 31, 2017 and December 31, 2017, as applicable. Non-GAAP financial measures should not be considered in isolation or as a substitute for the Company's reported results prepared in accordance with GAAP.
