ATLAS ENERGY GROUP, LLC REPORTS OPERATING AND FINANCIAL RESULTS FOR THE SECOND QUARTER 2015

Pittsburgh, PA – August 6, 2015 - Atlas Energy Group, LLC (NYSE: ATLS) (“Atlas Energy”, the “Company” or “ATLS”) today reported operating and financial results for the second quarter 2015.

• Atlas Energy’s Distributable Cash Flow, a non-GAAP measure, was approximately $5.0 million⁽¹⁾, or $0.19 per common unit, in the second quarter 2015.

• Atlas Resource Partners, L.P. (NYSE: ARP), Atlas Energy’s E&P subsidiary, paid monthly cash distributions totaling $0.325 per common limited partner unit for the second quarter 2015. The most recent ARP distribution for June 2015 will be paid on August 14, 2015 to holders of record as of August 7, 2015. Atlas Energy received $9.4 million in cash distributions in the second quarter 2015 from ownership in ARP.

• Atlas Growth Partners, L.P. (“AGP”), Atlas Energy’s private E&P development subsidiary, recently completed its initial fundraising of approximately $233 million in investor capital for its operations, which are primarily focused in the Eagle Ford Shale.

• In July 2015, Arc Logistics Partners, LP (NYSE: ARCX), a master limited partnership of which 16% of its general partner is owned by ATLS through the Company’s interest in Lightfoot Capital Partners, announced that it acquired all of the limited liability company interests of UET Midstream, LLC, a crude oil and terminal business, from United Energy Trading, LLC and Hawkeye Midstream, LLC for a total adjusted purchase price of $76.6 million.

ATLS owns 100% of ARP’s general partner Class A units and incentive distribution rights, and an approximate 25% limited partner interest in ARP. ATLS’ financial results are presented on a consolidated basis with those of ARP. Non-controlling interests in ARP are reflected as an adjustment to net income in ATLS’ consolidated statements of operations and as a component of unitholders’ equity on its consolidated balance sheets. A consolidating statement of operations and balance sheet have also been provided in the financial tables to this release for the comparable periods presented. Please refer to the ARP second quarter 2015 earnings release for additional details on its financial results.

Recent Events

Sale of Arkoma Properties to ARP

On June 5, 2015, ARP acquired Atlas Energy’s natural gas producing properties in the Arkoma basin for approximately $35.5 million. The Arkoma assets consist of approximately 41 billion cubic feet (“Bcf”) of mature, low-decline natural gas reserves, which currently produce approximately 10.5 million cubic feet per day from over 550 active wells. ATLS used the net proceeds from the sale of the Arkoma assets to pay down a portion of its existing term loan, which had a carrying value of $77.4 million, net of unamortized discount of $5.3 million, on its consolidated balance sheet as of June 30, 2015. ATLS and ARP accounted for the Arkoma acquisition as a transaction between entities under common control, and accordingly recast the comparative prior periods presented as if the transaction had occurred at the beginning of the respective periods.

ARP’s Second Quarter 2015 Highlights

• ARP’s average net daily production for the second quarter 2015 was 270.8 million cubic feet equivalents per day (“Mmcfed”), as compared to 273.0 Mmcfed for the prior year second quarter. ARP’s second quarter 2015 production was comprised of 81% natural gas, 12% oil and 7% natural gas liquids. Oil volumes increased to 5,293 barrels per day (“bpd”) in the second quarter 2015, compared to 2,084 bpd in the prior year quarter. The increase in oil volumes was due primarily to the acquisition of oil-rich production in the Eagle Ford Shale and Rangely field in 2014.

• ARP’s net realized price for natural gas including the effect of hedge positions was $3.33 per thousand cubic feet (“mcf”) for the second quarter 2015, compared to $3.79/mcf for the prior year second quarter. Net realized oil prices including the effect of hedge positions averaged $83.19 per barrel (“bbl”) for the second quarter 2015, compared to $90.66/bbl for the prior year second quarter. ARP was hedged approximately 73% on its natural gas production in the second quarter 2015 and approximately 100% on its oil production.

• Investment partnership margin was $6.7 million in the second quarter 2015, compared with $10.2 million for the prior year comparable quarter. The decrease in investment partnership margin was due to more partnership wells being initiated in the prior year quarter which generated higher administration and oversight fees.

• For the remainder of 2015 and the full years 2016, 2017 and 2018, ARP is hedged approximately 72%, 67%, 62% and 51%, respectively, for its natural gas production at an average price of $4.17/mcf, and hedged approximately 100%, 85%, 62% and 59%, respectively, for oil at an average price of approximately $78/bbl based on second quarter 2015 average production. A summary of ARP’s derivative positions as of August 6, 2015 is provided in the financial tables of ARP’s second quarter earnings release.

Atlas Growth Partners

Atlas Energy’s private E&P development subsidiary, Atlas Growth Partners, L.P., completed its recent fundraising efforts during the second quarter 2015, accumulating approximately $233 million in investor capital. These funds are being deployed into AGP’s operations, namely in the oil-rich Eagle Ford Shale. AGP had net daily production of approximately 2,800 Mmcfed in the second quarter 2015, including production from 4 wells in the Eagle Ford Shale.

Corporate Expenses

• Cash general and administrative expense, excluding amounts attributable to AGP and ARP, was $2.0 million for the second quarter 2015, approximately $1.4 million lower than the first quarter 2015. The decrease in expense from the first quarter 2015 was due primarily to the seasonality of certain ATLS’ public company costs. Please refer to the consolidating statements of operations provided in the financial tables of this release.

• Cash interest expense was $2.3 million for the second quarter 2015, compared to $2.5 million for the prior year comparable quarter. ATLS had approximately $77.4 million of debt on its consolidated balance sheet at June 30, 2015, net of unamortized discount of $5.3 million, and a cash position of approximately $11.8 million.

⁽²⁾  “Mcf” and “Mcfd” represent thousand cubic feet and thousand cubic feet per day; “Mcfe” and “Mcfed” represent thousand cubic feet equivalents and thousand cubic feet equivalents per day, and “Bbl” and “Bpd” represent barrels and barrels per day. Barrels are converted to Mcfe using the ratio of six Mcf’s to one barrel.

⁽³⁾  ARP’s average sales prices for natural gas before the effects of financial hedging were $2.14 per Mcf and $4.13 per Mcf for the three months ended June 30, 2015 and 2014, respectively, and $2.34 per Mcf and $4.39 per Mcf for the six months ended June 30, 2015 and 2014, respectively. ARP’s amounts exclude the impact of subordination of ARP’s production revenues to investor partners within its investor partnerships. Including the effects of this subordination, ARP’s average natural gas sales prices were $3.28 per Mcf ($2.09 per Mcf before the effects of financial hedging) and $3.77 per Mcf ($4.12 per Mcf before the effects of financial hedging) for the three months ended June 30, 2015 and 2014, respectively, and $3.40 per Mcf ($2.29 per Mcf before the effects of financial hedging) and $3.79 per Mcf ($4.26 per Mcf before the effects of financial hedging) for the six months ended June 30, 2015 and 2014, respectively.

⁽⁴⁾  AGP’s average sales price for oil before the effects of financial hedging was $55.84 per barrel and $96.53 per barrel for the three months ended June 30, 2015 and 2014, respectively, and $49.72 per barrel and $93.77 per barrel for the six months ended June 30, 2015 and 2014, respectively. ARP’s average sales prices for oil before the effects of financial hedging were $53.35 per barrel and $98.95 per barrel for the three months ended June 30, 2015 and 2014, respectively, and $48.32 per barrel and $96.49 per barrel for the six months ended June 30, 2015 and 2014, respectively.

⁽⁵⁾  ARP’s average sales prices for natural gas liquids before the effects of financial hedging were $13.78 per barrel and $28.93 per barrel for the three months ended June 30, 2015 and 2014, respectively, and $13.95 per barrel and $32.15 per barrel for the six months ended June 30, 2015 and 2014, respectively.

⁽⁶⁾  Production costs include labor to operate the wells and related equipment, repairs and maintenance, materials and supplies, property taxes, severance taxes, insurance, production overhead and transportation and compression expenses. These amounts exclude the effects of ARP’s proportionate share of lease operating expenses associated with subordination of production revenue to investor partners within ARP’s investor partnerships. Including the effects of these costs, ARP’s lease operating expenses per Mcfe were $1.34 per Mcfe ($1.75 per Mcfe for total production costs) and $1.23 per Mcfe ($1.74 per Mcfe for total production costs) for the three months ended June 30, 2015 and 2014, respectively, and $1.34 per Mcfe ($1.77 per Mcfe for total production costs) and $1.16 per Mcfe ($1.70 per Mcfe for total production costs) for the six months ended June 30, 2015 and 2014, respectively. Including the effects of these costs, total lease operating expenses per Mcfe were $1.34 per Mcfe ($1.75 per Mcfe for total production costs) and $1.24 per Mcfe ($1.75 per Mcfe for total production costs) for the three months ended June 30, 2015 and 2014, respectively, and $1.33 per Mcfe ($1.77 per Mcfe for total production costs) and $1.17 per Mcfe ($1.71 per Mcfe for total production costs) for the six months ended June 30, 2015 and 2014, respectively.

⁽¹⁾  EBITDA and Distributable Cash Flow is relevant and useful because it helps ATLS’ investors understand its operating performance, allows for easier comparison of its results with other master limited partnerships (“MLP”), and is a critical component in the determination of quarterly cash distributions. As a MLP, ATLS is required to distribute 100% of available cash, as defined in its limited partnership agreement (“Available Cash”) and subject to cash reserves established by its general partner, to investors on a quarterly basis. ATLS refers to Available Cash prior to the establishment of cash reserves as DCF. EBITDA, Adjusted EBITDA and DCF should not be considered in isolation of, or as a substitute for, net income as an indicator of operating performance or cash flows from operating activities as a measure of liquidity. While ATLS’ management believes that its methodology of calculating EBITDA, Adjusted EBITDA and DCF is generally consistent with the common practice of other MLPs, such metrics may not be consistent and, as such, may not be comparable to measures reported by other MLPs, who may use other adjustments related to their specific businesses. EBITDA, Adjusted EBITDA and DCF are supplemental financial measures used by ATLS’ management and by external users of ATLS’ financial statements such as investors, lenders under its credit facilities, research analysts, rating agencies and others to assess its:

• Operating performance as compared to other publicly traded partnerships and other companies in the upstream and midstream energy sectors, without regard to financing methods, historical cost basis or capital structure;

• Ability to generate sufficient cash flows to support its distributions to unitholders;

• Ability to incur and service debt and fund capital expansion;

• Viability of potential acquisitions and other capital expenditure projects; and

• Ability to comply with financial covenants in its debt facility, which is calculated based upon Adjusted EBITDA.

11

DCF is determined by calculating EBITDA, adjusting it for non-cash, non-recurring and other items to achieve Adjusted EBITDA, and then deducting cash interest expense and maintenance capital expenditures. ATLS defines EBITDA as net income (loss) plus the following adjustments:

• Interest expense;

• Income tax expense;

• Depreciation, depletion and amortization.

ATLS defines Adjusted EBITDA as EBITDA plus the following adjustments:

• Cash distributions paid by ARP and AGP within 45 days after the end of the respective quarter, based upon their distributable cash flow generated during that quarter;

• Asset impairments;

• Acquisition and related costs;

• Non-cash stock compensation;

• (Gains) losses on asset disposal;

• Cash proceeds received from monetization of derivative transactions;

• Amortization of premiums paid on swaption derivative contracts; and

• Other items.

ATLS adjusts DCF for non-cash, non-recurring and other items for the sole purpose of evaluating its cash distribution for the quarterly period, with EBITDA and Adjusted EBITDA adjusted in the same manner for consistency. ATLS defines DCF as Adjusted EBITDA less the following adjustments:

• Cash interest expense; and

• Maintenance capital expenditures.

⁽²⁾  In accordance with prevailing accounting literature, ATLS has adjusted its historical financial statements to present them combined with the historical financial results of the spin-off assets for all periods prior to its spin-off date of February 27, 2015.

⁽³⁾  Represents the cash distribution paid by ARP and AGP within 45 days after the end of each quarter, based upon the distributable cash flow generated during the respective quarter.

⁽⁴⁾  Excludes non-cash stock compensation expense and certain non-recurring spinoff costs and acquisition and related costs.

⁽⁵⁾  Excludes non-cash amortization of deferred financing costs.
