CONE MIDSTREAM PARTNERS LP

NOTES TO CONSOLIDATED UNAUDITED FINANCIAL STATEMENTS

NOTE 1—DESCRIPTION OF BUSINESS, INITIAL PUBLIC OFFERING AND BASIS OF PRESENTATION

Description of Business

CONE Midstream Partners LP (the “Partnership”) is a master limited partnership formed in May 2014 by CONSOL Energy Inc. (NYSE: CNX) (“CONSOL”) and Noble Energy, Inc. (NYSE: NBL) (“Noble Energy”), whom we refer to collectively as our Sponsors, to own, operate, develop and acquire natural gas gathering and other midstream energy assets to service our Sponsors’ production in the Marcellus Shale in Pennsylvania and West Virginia. Our assets include natural gas gathering pipelines and compression and dehydration facilities, as well as condensate gathering, collection, separation and stabilization facilities.

In order to effectively manage our business we have divided our current midstream assets among three separate categories that we refer to as our “Anchor Systems,” “Growth Systems” and “Additional Systems” based on their relative current cash flows, growth profiles, capital expenditure requirements and the timing of their development.

• Our Anchor Systems include our midstream systems that generate the substantial majority of our current cash flows and that we expect to drive our growth over the near term as we increase average throughput on these systems from our Sponsors’ growing production.

• Our Growth Systems include our high-growth, developing gathering systems that will require substantial expansion capital expenditures over the next several years, the substantial majority of which will be funded by our Sponsors in proportion to their retained ownership interest.

• Our Additional Systems include several gathering systems primarily located in the wet gas regions of our Sponsors' dedicated acreage that we expect will generate stable cash flows and require lower levels of expansion capital investment over the next several years.

On September 30, 2014, the Partnership closed its initial public offering ("IPO") of common units representing limited partner interests. The Partnership's general partner is CONE Midstream GP LLC (the "general partner"), a wholly owned subsidiary of CONE Gathering LLC ("CONE Gathering"). CONE Gathering, a Delaware limited liability company, is a joint venture formed by our Sponsors in September 2011 and represents the predecessor for accounting purposes (the "Predecessor") of CONE Midstream Partners LP. References in these consolidated financial statements to “our partnership,” “we,” “our,” “us” or like terms, when used for periods prior to the IPO, refer to CONE Gathering. References in these consolidated financial statements to “our partnership,” “we,” “our,” “us” or like terms, when used for periods beginning at or following the IPO, refer collectively to the Partnership and its consolidated subsidiaries. For periods prior to the IPO, the accompanying consolidated financial statements and related notes include the assets, liabilities and results of operations of CONE Gathering.

In order to maintain operational flexibility, our operations are conducted through, and our operating assets are owned by, our operating subsidiaries. However, neither we nor our operating subsidiaries have any employees. Our general partner has the sole responsibility for providing the personnel necessary to conduct our operations, whether through directly hiring employees or by obtaining the services of personnel employed by our Sponsors or others. All of the personnel that conduct our business are employed or contracted by our general partner and its affiliates, including our Sponsors, but we sometimes refer to these individuals as our employees because they provide services directly to us.

Initial Public Offering

On September 30, 2014, the Partnership closed its IPO of 20,125,000 common units at a price to the public of $22.00 per unit, which included 2,625,000 common units issued pursuant to the underwriters' exercise in full of their over-allotment option. The Partnership’s common units are listed on the New York Stock Exchange under the ticker symbol “CNNX.”

Concurrent with the closing of the IPO, CONE Gathering contributed to the Partnership a 75% controlling interest in the Anchor Systems, a 5% controlling interest in the Growth Systems and a 5% controlling interest in the Additional Systems. In exchange for CONE Gathering's contribution of assets and liabilities to the Partnership, CONE Gathering received:

• through its ownership of our general partner, a continuation of a 2% general partner interest in the partnership;

• 9,038,121 common units and 29,163,121 subordinated units, representing an aggregate 64.2% limited partner interest in the Partnership (the common and subordinated units were subsequently distributed to the Sponsors);

• through its ownership of our general partner, all of the Partnerships' incentive distribution rights; and

• an aggregate cash distribution of $408.0 million.

Basis of Presentation

The accompanying unaudited consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States ("GAAP"). To conform to these accounting principles, management makes estimates and assumptions that affect the amounts reported in the consolidated financial statements and the notes thereto. These estimates are evaluated on an ongoing basis, utilizing historical experience and other methods considered reasonable under the particular circumstances. Although these estimates are based on management’s best available knowledge at the time, changes in facts and circumstances or discovery of new facts or circumstances may result in revised estimates. Actual results may differ from these estimates. Effects on the Partnership’s business, financial position and results of operations resulting from revisions to estimates are recognized when the facts that give rise to the revision become known.

The balance sheet at December 31, 2014 has been derived from the audited financial statements at that date but does not include all of the information and footnotes required by GAAP for complete financial statements.

NOTE 2 — SIGNIFICANT ACCOUNTING POLICIES

A summary of the significant accounting policies is included below. These, together with the other notes to the Financial Statements, are an integral part of the Financial Statements.

Under the Jumpstart Our Business Startups Act ("JOBS Act"), for as long as the Partnership remains an “emerging growth company” as defined in the JOBS Act, we may take advantage of certain exemptions from the Securities and Exchange Commission's ("SEC") reporting requirements that are applicable to other public companies that are not emerging growth companies, including not being required to provide an auditor’s attestation report on management’s assessment of the effectiveness of its system of internal control over financial reporting pursuant to Section 404 of the Sarbanes-Oxley Act, reduced disclosure obligations regarding executive compensation in our periodic reports, and exemptions from the requirements of holding a nonbinding advisory vote on executive compensation and seeking unitholder approval of any golden parachute payments not previously approved. We may take advantage of these reporting exemptions until we are no longer an emerging growth company.

The Partnership will remain an emerging growth company for up to five years from the date of our initial public offering, although we will lose that status sooner if:

• we have more than $1.0 billion of revenues in a fiscal year;

• the limited partner interests held by non-affiliates have a market value of more than $700 million; or

• we issue more than $1.0 billion of non-convertible debt over a three-year period.

The JOBS Act also provides that an emerging growth company can delay adopting new or revised accounting standards until such time as those standards apply to private companies. The Partnership irrevocably elected to “opt out” of this exemption and, therefore, is and will be subject to the same new or revised accounting standards as other public companies that are not emerging growth companies.

Principles of Consolidation

The consolidated financial statements include the accounts of CONE Midstream Partners LP and all of its controlled subsidiaries. Transactions between the Partnership and its Sponsors have been identified in the consolidated financial statements as transactions between related parties and are discussed in Note 4.

Use of Estimates

The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets, liabilities, revenues and expenses, and various disclosures. Actual results could differ from those estimates.

Revenue Recognition

Revenues are recognized for the transportation of natural gas and other hydrocarbons based on the delivery of actual volumes transported at a contracted throughput rate. Operating fees received are recorded in gathering revenue — related party in the period the service is performed.

Accounts Receivable

Accounts receivable are recorded at the invoiced amount and do not bear interest. When applicable, we reserve for specific accounts receivable when it is probable that all or a part of an outstanding balance will not be collected, such as customer bankruptcies. Collectability is determined based on terms of sale, credit status of customers and various other circumstances. We regularly review collectability and establish or adjust the allowance as necessary using the specific

8

identification method. Account balances are charged off against the allowance after all means of collection have been exhausted and the potential for recovery is considered remote. There were no reserves for uncollectible amounts in the periods presented.

Inventory

Inventory is stated at the lower of cost or market and consists of pipe purchased for a pipeline project that has been delayed.  The cost is determined primarily under the specific identification method.  The Partnership expects the pipe will be used in an alternative project or sold to a third party.

Property and Equipment

Property and equipment is recorded at cost upon acquisition. Expenditures which extend the useful lives of existing property and equipment are capitalized.

Depreciation of property and equipment is calculated on the straight-line method over the estimated useful lives or lease terms of the assets.

When properties are retired or otherwise disposed, the related cost and accumulated depreciation are removed from the respective accounts and any profit or loss on disposition is recognized as gain or loss. There were no retirements or disposals during the periods presented.

The Partnership evaluates whether long-lived assets have been impaired and determines if the carrying amount of its assets may not be recoverable. For such long-lived assets, impairment exists when the carrying amount of an asset exceeds estimates of the undiscounted cash flows expected to result from the use and eventual disposition of the asset. If the carrying amount of the long-lived asset is not recoverable, based on the estimated future undiscounted cash flows, the impairment loss is measured as the excess of the asset’s carrying amount over its estimated fair value.

Fair value represents the estimated price between market participants to sell an asset in the principal or most advantageous market for the asset, based on assumptions a market participant would make. When warranted, management assesses the fair value of long-lived assets using commonly accepted techniques and may use more than one source in making such assessments. Sources used to determine fair value include, but are not limited to, recent third-party comparable sales, internally developed discounted cash flow analyses and analyses from outside advisors. Significant changes, such as the condition of an asset or management’s intent to utilize the asset generally require management to reassess the cash flows related to long-lived assets. No impairments were identified during the periods presented.

Variable Interest Entities

The Anchor, Growth and Additional Limited Partnerships (the "Limited Partnerships"), which are variable interest entities, are consolidated by CONE Midstream Partners LP through its ownership of CONE Midstream Operating Company LLC. CONE Midstream Operating Company LLC, through its general partner ownership interest in each of the Anchor, Growth and Additional Limited Partnerships, has the power to direct all substantive strategic and day-to-day operational decisions of the Limited Partnerships. CONE Midstream Operating Company LLC is considered to be the primary beneficiary for accounting purposes. 

Environmental Matters

We are subject to various federal, state and local laws and regulations relating to the protection of the environment. Environmental expenditures that relate to current operations are expensed or capitalized as appropriate. Expenditures that relate to an existing condition caused by past operations, and do not contribute to current or future revenue generation, are expensed. Liabilities are recorded when environmental assessments and/or clean-ups are probable, and the costs can be reasonably estimated. At this time, we are unable to assess the timing and/or effect of potential liabilities related to greenhouse gas emissions or other environmental issues. As of September 30, 2015, we had no material environmental matters that required specific disclosure or requiring the recognition of a liability.

Asset Retirement Obligations

We perform an ongoing analysis of asset removal and site restoration costs that we may be required to perform under law or contract once an asset has been permanently taken out of service. We have property and equipment at locations that we own and at sites leased or under right of way agreements. We are under no contractual obligation to remove the assets at locations we own. In evaluating our asset retirement obligation, we review lease agreements, right of way agreements, easements and permits to determine which agreements, if any, require an asset removal and restoration obligation. Determination of the amounts to be recognized is based upon numerous estimates and assumptions, including expected settlement dates, future retirement costs, future inflation rates and the credit-adjusted-risk-free interest rates. We operate and maintain our midstream systems and intend to do so as long as supply and demand for natural gas exists, which we expect for the foreseeable future.

9

Therefore, we believe that we cannot reasonably estimate the asset retirement obligations for our midstream system assets as these assets have indeterminate lives.

Income Taxes

Our operations as a limited partnership, and our Predecessor, as a limited liability company, are treated as partnerships for federal and state income tax purposes, with each partner being separately taxed on its share of the taxable income. Accordingly, no provision for federal or state income taxes has been recorded in the consolidated financial statements.

Cash Distributions

Our partnership agreement requires that we distribute all of our available cash within 45 days after the end of each quarterly period to unitholders of record on the applicable record date. This requirement forms the basis of our cash distribution policy and reflects a basic judgment that our unitholders will be better served by distributing our available cash rather than retaining it because, among other reasons, we believe we will generally finance any expansion capital expenditures from external financing sources. Under our current cash distribution policy, we intend to make a minimum quarterly distribution to the holders of our common units and subordinated units of $0.2125 per unit, or $0.85 per unit on an annualized basis, to the extent we have sufficient available cash after the establishment of cash reserves and the payment of costs and expenses, including the payment of expenses to our general partner. However, other than the requirement in our partnership agreement to distribute all of our available cash each quarter, we have no legal obligation to make quarterly cash distributions in this or any other amount, and the board of directors of our general partner has considerable discretion to determine the amount of our available cash each quarter. In addition, the board of directors of our general partner may change our cash distribution policy at any time, subject to the requirement in our partnership agreement to distribute all of our available cash quarterly.

Generally, our available cash is the sum of (i) all cash on hand at the end of a quarter after the payment of our expenses and the establishment of cash reserves and (ii) if the board of directors of our general partner so determines, all or any portion of additional cash on hand resulting from working capital borrowings made after the end of the quarter.

The following table illustrates the percentage allocations of available cash from operating surplus between the unitholders and our general partner based on the specified target distribution levels. The amounts set forth under “Marginal Percentage Interest in Distributions” are the percentage interests of our general partner and the unitholders in any available cash from operating surplus we distribute up to and including the corresponding amount in the column “Total Quarterly Distribution Per Unit Target Amount.” The percentage interests shown for our unitholders and our general partner for the minimum quarterly distribution are also applicable to quarterly distribution amounts that are less than the minimum quarterly distribution.

The percentage interests set forth below for our general partner include its 2% general partner interest and assume that our general partner has contributed any additional capital necessary to maintain its 2% general partner interest, our general partner has not transferred its incentive distribution rights and there are no arrearages on common units.

			Marginal Percentage Interest in Distributions
Distribution Targets	Total Quarterly Distribution Per Unit Target Amount		Unitholders	General Partner
Minimum Quarterly Distribution		$0.2125	98%	2%
First Target Distribution	Above $0.2125	up to $0.24438	98%	2%
Second Target Distribution	Above $0.24438	up to $0.26563	85%	15%
Third Target Distribution	Above $0.26563	up to $0.31875	75%	25%
Thereafter	Above $0.31875		50%	50%

Subordinated Units

Our partnership agreement provides that, during the subordination period, the common unitholders will have the right to receive distributions of available cash from operating surplus each quarter in an amount equal to $0.2125 per unit, which is defined in our partnership agreement as the minimum quarterly distribution, plus any arrearages in the payment of the minimum quarterly distribution on the common units from prior quarters, before any distributions of available cash from operating surplus may be made on the subordinated units. The practical effect of the subordinated units is to increase the likelihood that, during the subordination period, there will be available cash to be distributed on the common units. The

10

subordination period will end, and the subordinated units will convert to common units, on a one-for-one basis, when certain distribution requirements, as defined in the partnership agreement, have been met.

Subordination Period

Except as described below, the subordination period began on the closing date of the IPO and will extend until the first business day following the distribution of available cash in respect of any quarter beginning after September 30, 2017, that each of the following tests are met:

• distributions of available cash from operating surplus on each of the outstanding common units and subordinated units and the corresponding distributions on the 2% general partner interest equaled or exceeded $0.85 (the annualized minimum quarterly distribution), for each of the three consecutive, non-overlapping four-quarter periods immediately preceding that date;

• the adjusted operating surplus (as defined below) generated during each of the three consecutive, non-overlapping four-quarter periods immediately preceding that date equaled or exceeded the sum of $0.85 (the annualized minimum quarterly distribution) on all of the outstanding common units and subordinated units and the corresponding distributions on the 2% general partner interest during those periods on a fully diluted basis; and

• there are no arrearages in payment of the minimum quarterly distribution on the common units.

Early Termination of the Subordination Period

The subordination period will automatically terminate on the first business day following the distribution of available cash in respect of any quarter, beginning with the quarter ending September 30, 2015, that each of the following tests are met: 

• distributions of available cash from operating surplus on each of the outstanding common units and subordinated units and the corresponding distributions on the 2% general partner interest equaled or exceeded $1.275 (150% of the annualized minimum quarterly distribution), plus the related distributions on the incentive distribution rights, for the four-quarter period immediately preceding that date;

• the adjusted operating surplus (as defined below) generated during the four-quarter period immediately preceding that date equaled or exceeded the sum of (i) $1.275 (150% of the annualized minimum quarterly distribution) on all of the outstanding common units and subordinated units and the corresponding distributions on the 2% general partner interest during that period on a fully diluted basis and (ii) the corresponding distributions on the incentive distribution rights; and

• there are no arrearages in payment of the minimum quarterly distribution on the common units.

Expiration of the Subordination Period

When the subordination period ends, each outstanding subordinated unit will convert into one common unit and will thereafter participate pro rata with the other common units in distributions of available cash.

Adjusted Operating Surplus

Adjusted operating surplus is intended to reflect the cash generated from operations during a particular period and therefore excludes net drawdowns of reserves of cash established in prior periods. Adjusted operating surplus for a period consists of:

• operating surplus generated with respect to that period; less

• any net increase in working capital borrowings with respect to that period; less

• any net decrease in cash reserves for operating expenditures with respect to that period not relating to an operating expenditure made with respect to that period; plus

• any net decrease in working capital borrowings with respect to that period; plus

• any net decrease made in subsequent periods to cash reserves for operating expenditures initially established with respect to that period to the extent such decrease results in a reduction in adjusted operating surplus in subsequent periods; plus

• any net increase in cash reserves for operating expenditures with respect to that period required by any debt instrument for the repayment of principal, interest or premium.

Incentive Distribution Rights ("IDRs")

All of the IDRs are currently held by CONE Midstream GP LLC, our general partner. Incentive distribution rights represent the right to receive an increasing percentage (13.0%, 23.0% and 48.0%) of quarterly distributions of available cash

11

from operating surplus after the minimum quarterly distribution and the target distribution levels described below have been achieved. Our general partner may transfer the IDRs separately from its general partner interest.

The following discussion assumes that our general partner maintains its 2% general partner interest and that our general partner continues to own the IDRs.

If for any quarter:

• we have distributed available cash from operating surplus to the common unitholders and subordinated unitholders in an amount equal to the minimum quarterly distribution; and

• we have distributed available cash from operating surplus on outstanding common units in an amount necessary to eliminate any cumulative arrearages in payment of the minimum quarterly distribution;

then, we will distribute any additional available cash from operating surplus for that quarter among the unitholders and our general partner in the following manner:

• first, 98% to all unitholders, pro rata, and 2% to our general partner, until each unitholder receives a total of $0.24438 per unit for that quarter (the “first target distribution”);

• second, 85% to all unitholders, pro rata, and 15% to our general partner, until each unitholder receives a total of $0.26563 per unit for that quarter (the “second target distribution”);

• third, 75% to all unitholders, pro rata, and 25% to our general partner, until each unitholder receives a total of $0.31875 per unit for that quarter (the “third target distribution”); and

• thereafter, 50% to all unitholders, pro rata, and 50% to our general partner.

Reclassifications

Certain amounts in prior periods have been reclassified to conform to the current reporting classifications with no effect on previously reported net income or partners' capital.

Recent Accounting Pronouncements

In May 2014, the FASB issued 2014-09 "Revenue from Contracts with Customers (Topic 606)". The objective of the amendments in this update is to improve financial reporting by creating common revenue recognition guidance for U.S. GAAP and International Financial Reporting Standards ("IFRS"). The guidance in this update supersedes the revenue recognition requirements in Topic 605, Revenue Recognition, and most industry-specific guidance throughout the Industry Topics of the Codification. The core principle of the guidance is that an entity should recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. An entity should disclose sufficient information, both qualitative and quantitative, to enable users of financial statements to understand the nature, amount, timing, and uncertainty of revenue and cash flows arising from contracts with customers. In August 2015, the FASB issued a standard to delay the effective date by one year. In accordance with this delay, the new standard is effective for annual reporting periods beginning after December 15, 2018, with the option to adopt as early as annual reporting periods beginning after December 15, 2016. We are currently evaluating the method of adoption and impact that this new standard will have on our financial statements.

In April 2015, the FASB issued ASU 2015-06 "Earnings Per Share (Topic 260): Effects on Historical Earnings per Unit of Master Limited Partnership Dropdown Transactions".  ASU 2015-06 specifies that for purposes of calculating historical earnings per unit under the two-class method, the earnings or losses of a transferred business before the date of a dropdown transaction should be allocated entirely to the general partner. In that circumstance, the previously reported earnings per unit of the limited partners, which is typically the earnings per unit measure presented in the financial statements, would not change as a result of the dropdown transaction. This ASU is effective for annual and interim reporting periods beginning after December 15, 2015 and is required to be applied retrospectively. The Partnership believes adoption of this new standard will not have a material impact on the Partnership's financial statements.

In April 2015, the FASB issued ASU 2015-03 "Interest - Imputation of Interest: Simplifying the Presentation of Debt Issuance Costs" ("ASU 2015-3"), which attempted to simplify the presentation of debt issuance costs by requiring that such costs be presented as a deduction from the corresponding debt liability. In August 2015, the FASB issued ASU No. 2015-15 "Interest - Imputation of Interest (Subtopic 835-30): Presentation and Subsequent Measurement of Debt Issuance Costs Associated with Line-of-Credit Arrangements", which clarified ASU 2015-3 as it relates to line-of-credit arrangements. ASU 2015-15 states that the SEC staff would not object to an entity's decision to continue to present debt issuance costs as an asset and subsequently amortize the deferred debt issuance costs ratably over the term of the line-of-credit arrangement, regardless of whether there are any outstanding borrowings on the line-of-credit arrangement. Because this is how the Partnership has historically accounted for debt issuance costs, adoption of this standard will not have any impact on reported results or disclosures.

12

In February 2015, the FASB issued ASU No. 2015-02, "Consolidation: Amendments to the Consolidation Analysis. ASU 2015-02 changes the analysis that a reporting entity must perform to determine whether it should consolidate certain types of legal entities. The ASU will be effective for annual reporting periods beginning after December 15, 2015, including interim periods therein. The Partnership believes adoption of this new standard will not have a material impact on the Partnership's financial statements.

NOTE 3 — NET INCOME PER LIMITED PARTNER AND GENERAL PARTNER INTEREST

We allocate net income among our general partner and limited partners using the two-class method in accordance with applicable authoritative accounting guidance. Under the two-class method, we allocate net income to our limited partners, our general partner and the holders of our IDRs in accordance with the terms of our partnership agreement. We also allocate any earnings in excess of distributions to our limited partners, our general partner and the holders of the IDRs in accordance with the terms of our partnership agreement. We allocate any distributions in excess of earnings for the period to our general partner and our limited partners based on their respective proportionate ownership interests in us, after taking into account distributions to be paid with respect to the IDRs, as set forth in our partnership agreement.

Diluted net income per limited partner unit reflects the potential dilution that could occur if securities or agreements to issue common units, such as awards under the long-term incentive plan, were exercised, settled or converted into common units.  When it is determined that potential common units resulting from an award subject to performance or market conditions should be included in the diluted net income per limited partner unit calculation, the impact is reflected by applying the treasury stock method. There were 13,258 and 34,940 phantom units included in the calculation of diluted net income per limited partner unit for the respective three and nine months ended September 30, 2015. There were 21,682 phantom units that were not included in the calculation for the three months ended September 30, 2015 because the effect would have been antidilutive.

The following table illustrates the Partnership’s calculation of net income per unit for common and subordinated partner units:

NOTE 4 — RELATED PARTY

In the ordinary course of business, the Partnership has transactions with related parties that result in affiliate transactions. Related parties during each of the periods presented included CONSOL and certain of its subsidiaries and Noble Energy, to whom we provide natural gas gathering and compression services.

Transactions with related parties, other than certain transactions with CONSOL and Noble Energy related to administrative services, were conducted on terms which management believes are comparable to those with unrelated parties. We believe such costs would not have been materially different had they been calculated on a stand-alone basis.

Charges for services from CONSOL included in operating expenses — related party were $8.1 million and $6.0 million for the three months ended September 30, 2015 and 2014 and $22.1 million and $18.6 million for the nine months ended September 30, 2015 and 2014, respectively. There were no charges from Noble Energy included in operating expenses — related party for the three and nine months ended September 30, 2015 and 2014.

During the nine months ended September 30, 2015, CONSOL purchased $2.2 million of supply inventory from the Partnership, none of which occurred in the quarter ended September 30, 2015. Purchases of supply inventory from a CONSOL subsidiary were $1.1 million for the three months ended September 30, 2014 and $3.6 million for the nine months ended September 30, 2014 and were included in operating expenses — related party.

Additionally, charges by each Sponsor included in general and administrative expense - related party consisted of the following:

(dollars in thousands)	Three Months Ended   September 30,				Nine Months Ended   September 30,
	2015		2014		2015		2014
CONSOL	$	2,278	$	1,599	$	5,974	$	2,957
Noble Energy	135		—		411		—
Total General and Administrative Expense — Related Party	$	2,413	$	1,599	$	6,385	$	2,957

Omnibus Agreement

Concurrent with closing the IPO, we entered into an omnibus agreement with CONSOL, Noble Energy, CONE Gathering and our general partner that addresses the following matters:

• our payment of an annual administrative support fee, initially in the amount of $0.6 million (prorated for the first year of service), for the provision of certain services by CONSOL and its affiliates;

• our payment of an annual administrative support fee, initially in the amount of approximately $0.6 million (pro rated for the first year of service), for the provision of certain executive services by CONSOL and its affiliates;

• our payment of an annual administrative support fee, initially in the amount of approximately $0.2 million (pro rated for the first year of service), for the provision of certain executive services by Noble Energy and its affiliates;

• our obligation to reimburse our Sponsors for all other direct or allocated costs and expenses incurred by our Sponsors in providing general and administrative services (which reimbursement is in addition to certain expenses of our general partner and its affiliates that are reimbursed under our partnership agreement);

• our right of first offer to acquire (i) CONE Gathering’s retained interests in each of our Anchor Systems, Growth Systems and Additional Systems, (ii) CONE Gathering’s other ancillary midstream assets and (iii) any additional midstream assets that CONE Gathering develops; and

• an indemnity from CONE Gathering for liabilities associated with the use, ownership or operation of our assets, including environmental liabilities, to the extent relating to the period of time prior to the closing of the IPO; and our obligation to indemnify CONE Gathering for events and conditions associated with the use, ownership or operation of our assets that occur after the closing of the IPO, including environmental liabilities.

So long as CONE Gathering controls our general partner, the omnibus agreement will remain in full force and effect. If CONE Gathering ceases to control our general partner, either party may terminate the omnibus agreement, provided that the indemnification obligations will remain in full force and effect in accordance with their terms.

Operational Services Agreement

Concurrent with closing of the IPO, we entered into an operational services agreement with CONSOL under which CONSOL provides certain operational services to us in support of our gathering pipelines and dehydration, treating and compressor stations and facilities, including routine and emergency maintenance and repair services, routine operational

14

activities, routine administrative services, construction and related services and such other services as we and CONSOL may mutually agree upon from time to time. CONSOL will prepare and submit for our approval a maintenance, operating and capital budget on an annual basis. CONSOL will submit actual expenditures for reimbursement on a monthly basis and we will reimburse CONSOL for any direct third-party costs actually incurred by CONSOL in providing these services.

The operational services agreement has an initial term of 20 years and will continue in full force and effect unless terminated by either party at the end of the initial term or any time thereafter by giving not less than six months’ prior notice to the other party of such termination. CONSOL may terminate the operational services agreement if (1) we become insolvent, declare bankruptcy or take any action in furtherance of, or indicating our consent to, approval of, or acquiescence in, a similar proceeding or (2) upon not less than 180 days notice. We may immediately terminate the agreement (1) if CONSOL becomes insolvent, declares bankruptcy or takes any action in furtherance of, or indicating its consent to, approval of, or acquiescence in, a similar proceeding, (2) upon a finding of CONSOL’s willful misconduct or gross negligence that has had a material adverse effect on any of our gathering pipelines and dehydration, treating and compressor stations and facilities or our business or (3) CONSOL is in material breach of the operational services agreement and fails to cure such default within 45 days.

Under the operational services agreement, CONSOL will indemnify us from any claims, losses or liabilities incurred by us, including third-party claims, arising from CONSOL’s performance of the agreement to the extent caused by CONSOL’s gross negligence or willful misconduct. We will indemnify CONSOL from any claims, losses or liabilities incurred by CONSOL, including any third-party claims, arising from CONSOL’s performance of the agreement, except to the extent such claims, losses or liabilities are caused by CONSOL’s gross negligence or willful misconduct.

Gathering Agreements

CNX Gas Gathering Agreement

On September 30, 2014, in connection with the closing of the IPO, the Partnership entered into a Gathering Agreement (the “CNX Gas Gathering Agreement”) by and between the Partnership, as gatherer, and CNX Gas Company LLC (“CNX Gas”), a wholly owned subsidiary of CONSOL, as shipper. Under the CNX Gas Gathering Agreement, CNX Gas (i) dedicated to the Partnership for natural gas midstream services all of its existing acres and any acres acquired in the future, in each case, that are jointly owned with Noble Energy to the extent covering the Marcellus Shale in the dedication area and (ii) granted the Partnership a right of first offer to provide natural gas midstream services with respect to all of its existing acres and any acres acquired in the future, in each case, that are jointly owned with Noble Energy to the extent covering the Marcellus Shale in the right of first offer area.

The CNX Gas Gathering Agreement commenced on September 30, 2014 and has an initial term of 20 years. Under the CNX Gas Gathering Agreement, if the Partnership fails to timely complete the construction of the facilities necessary to provide midstream services to CNX Gas’ dedicated acreage or has an uncured default of any of the Partnership’s material obligations that has caused an interruption in the Partnership’s services for more than 90 days, the affected acreage will be permanently released from the Partnership’s dedication. Also, after the fifth anniversary of the CNX Gas Gathering Agreement, if CNX Gas drills a well that is located more than a certain distance from the Partnership’s current gathering system (and not included in the detailed drilling plan provided by CNX Gas and Noble Energy) and a third-party gatherer offers a lower cost of services, then the acreage associated with such well will be permanently released from the Partnership’s dedication.

Under the CNX Gas Gathering Agreement, the Partnership charges a fee based on the type and scope of midstream services provided. For the services provided (a) with respect to natural gas that does not require downstream processing, the Partnership receives a fee of $0.40 per MMBtu, (b) with respect to the natural gas that requires downstream processing, the Partnership receives a fee of $0.55 per MMBtu, except in the Pittsburgh International Airport and Moundsville (Marshall County, West Virginia) areas, where the fee is $0.275 per MMBtu and (c) with respect to condensate, the Partnership receives a fee of $5.00 per bbl in the Majorsville area and $2.50 per bbl in the Moundsville area.

NBL Gas Gathering Agreement

On September 30, 2014, in connection with the closing of the IPO, the Partnership entered into a Gathering Agreement (the “NBL Gas Gathering Agreement”) by and between the Partnership, as gatherer, and Noble Energy, as shipper. Under the NBL Gas Gathering Agreement, Noble Energy (i) dedicated to the Partnership for natural gas midstream services all of its existing acres and any acres acquired in the future, in each case, that are jointly owned with CNX Gas to the extent covering the Marcellus Shale in the dedication area and (ii) granted the Partnership a right of first offer to provide natural gas midstream services with respect to all of its existing acres and any acres acquired in the future, in each case, that are jointly owned with CNX Gas to the extent covering the Marcellus Shale in the right of first offer area.

Employee Secondment Agreement

We entered into an employee secondment agreement, effective September 8, 2014, with Noble Energy. Pursuant to the employee secondment agreement, an employee of Noble Energy is seconded to us to provide investor relations and similar functions. We will reimburse Noble Energy for allocable salary, benefits, insurance, payroll taxes and other employment expenses related to the seconded employee.

NOTE 12—SEGMENT INFORMATION

Operating segments are revenue-producing components of the enterprise for which separate financial information is produced internally and is subject to evaluation by the chief operating decision maker in deciding how to allocate resources.

In order to effectively manage our business we have divided our current midstream assets among three separate categories that we refer to as our “Anchor Systems,” “Growth Systems” and “Additional Systems” based on their relative current cash flows, growth profiles, capital expenditure requirements and the timing of their development.

All of the Partnership’s operating revenues, income from operations and assets are generated or located in the United States.

NOTE 13 — REVOLVING CREDIT FACILITY

In connection with the closing of our IPO on September 30, 2014, we entered into a credit facility agreement which provides for a $250 million unsecured five year revolving credit facility that matures on September 30, 2019. Our revolving credit facility is available for working capital, capital expenditures, certain acquisitions, distributions, unit repurchases and other lawful partnership purposes. Borrowings under our revolving credit facility will bear interest at our option at either:

• the base rate, which is defined as the highest of (i) the federal funds rate plus 0.50%; (ii) JP Morgan’s prime rate; or (iii) the daily LIBOR rate for a one month interest period plus 1.00%; in each case, plus a margin varying from 0.1250% to 1.00% depending on our most recent consolidated total leverage ratio; or

• the LIBOR rate plus a margin varying from 1.1250% to 2.00%, in each case, depending on our most recent consolidated leverage ratio (as defined in the agreement governing our revolving credit facility) or our credit rating, as the case may be.

Interest on base rate loans is payable quarterly. Interest on LIBOR loans is payable on the last day of each interest period or, in the case of interest periods longer than three months, every three months. The unused portion of our revolving credit facility is subject to a commitment fee ranging from 0.15% to 0.35% per annum depending on our most recent consolidated leverage ratio or our credit rating, as the case may be.

Our revolving credit facility contains covenants and conditions that, among other things, limit our ability to incur or guarantee additional debt, make cash distributions (though there will be an exception for distributions permitted under the partnership agreement, subject to certain customary conditions), incur certain liens or permit them to exist, make certain investments and acquisitions, enter into certain types of transactions with affiliates, merge or consolidate with another company, and transfer, sell or otherwise dispose of assets. We are also subject to covenants that require us to maintain certain financial ratios. For example, we may not permit the ratio of (i) consolidated total funded debt (as defined in the agreement governing our revolving credit facility) as of the last day of each fiscal quarter to (ii) consolidated EBITDA (as defined in the agreement governing our revolving credit facility) for the four consecutive fiscal quarters ending on the last day of such fiscal quarter to exceed (A) at any time other than during a qualified acquisition period (as defined in the agreement governing our revolving credit facility), 5.00 to 1.00 and (B) during a qualified acquisition period, 5.50 to 1.00. In addition, we may not permit the ratio of (i) consolidated EBITDA for the four consecutive fiscal quarters ending on the last day of each fiscal quarter to (ii) consolidated interest expense (as defined in the agreement governing our revolving credit facility) for such four consecutive fiscal quarters to be less than 3.00 to 1.00. We were in compliance with all relevant covenants at September 30, 2015.

The outstanding balance of our revolving credit facility and interest rates on the amounts drawn from our revolver consist of the following:

	September 30, 2015				December 31, 2014
(dollars in thousands, except percentages)	Debt		Interest Rate (1)		Debt		Interest Rate (1)
Credit Facility	$	56,500	3.75	%	$	31,300	3.75	%

⁽¹⁾ At September 30, 2015 and December 31, 2014, borrowings accrued interest at JP Morgan’s prime rate. The average interest rate for the three and nine months period ended September 30, 2015 were 2.36% and 3.03%, respectively.

As of September 30, 2015, we had outstanding debt issuance costs of $0.7 million which were incurred as part of the issuance of our credit facility and are being amortized in interest expense through September 30, 2019, which is the maturity date of the credit facility.

NOTE 14 — LONG-TERM INCENTIVE PLAN

Under the CONE Midstream Partners LP 2014 Long-Term Incentive Plan (our “LTIP”), our general partner may issue long-term equity based awards to directors, officers and employees of our general partner or its affiliates, or to any consultants, affiliates of our general partner or other individuals who perform services for us. These awards will be intended to compensate the recipients thereof for their continued service during the vesting period based on the performance of our common units and align their long-term interests with those of our unitholders. We will be responsible for the cost of awards granted under our LTIP and all determinations with respect to awards to be made under our LTIP will be made by the board of directors of our general partner or any committee thereof that may be established for such purpose or by any delegate of the board of directors or such committee, subject to applicable law, which we refer to as the plan administrator.

The LTIP limits the number of units that may be delivered pursuant to vested awards to 5,800,000 common units, subject to proportionate adjustment in the event of unit splits and similar events. Common units subject to awards that are canceled,

20

forfeited, withheld to satisfy exercise prices or tax withholding obligations or otherwise terminated without delivery of the common units will be available for delivery pursuant to other awards.

Since the IPO, the Partnership's general partner has granted 33,697 equity-based phantom units at a weighted average fair value of $19.98 that vest over periods of continued service with the Partnership. The value of the phantom units will be paid in common units or an amount of cash equal to the fair market value of a unit based on the grant date. Management intends to settle any vested phantom units in common units. The Partnership accounts for phantom units as equity awards and records compensation expense based on the fair value of the awards at their grant date fair value. Based on the vesting schedules of all awards, the Partnership recognized $0.1 million and $0.3 million of compensation expense for the three and nine months ended September 30, 2015, respectively, which is included in general and administrative expense - related party in the consolidated statements of operations.

ITEM 2. MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

You should read the following discussion of the financial condition and results of operations of CONE Midstream Partners LP in conjunction with the historical and unaudited interim consolidated financial statements and notes to the consolidated financial statements. Among other things, those historical, unaudited interim consolidated financial statements include more detailed information regarding the basis of presentation for the following information. This discussion contains forward-looking statements that involve risks and uncertainties. Our actual results could differ materially from those discussed in such forward-looking statements. Factors that could cause or contribute to such differences include, but are not limited to, those identified under "forward-looking statements" below and those discussed in the section entitled "Risk Factors" in the Partnership’s Annual Report on Form 10-K for the year ended December 31, 2014.

Executive Overview

We are a fee-based, growth-oriented master limited partnership formed by CONSOL and Noble Energy, whom we refer to as our Sponsors, to own, operate, develop and acquire natural gas gathering and other midstream energy assets to service our Sponsors’ production in the Marcellus Shale in Pennsylvania and West Virginia. Our assets include natural gas gathering pipelines and compression and dehydration facilities, as well as condensate gathering, collection, separation and stabilization facilities.

On September 30, 2014, the Partnership closed its initial public offering ("IPO") of common units representing limited partner interests. References in this report to “our Partnership,” “we,” “our,” “us” or like terms, when used for periods prior to the IPO, refer to CONE Gathering LLC ("CONE Gathering"), our predecessor for accounting purposes. References in this report to “our Partnership,” “we,” “our,” “us” or like terms, when used for periods beginning at or following the IPO, refer collectively to the Partnership and its consolidated subsidiaries. See Note 1 to the unaudited consolidated financial statements for more information

We generate all of our revenues under long-term, fixed-fee gathering agreements that we have entered into with each of our Sponsors that are intended to mitigate our direct commodity price exposure and enhance the stability of our cash flows. Our gathering agreements also include substantial acreage dedications in the Marcellus Shale.

How We Evaluate Our Operations

Our management uses a variety of financial and operating metrics to analyze our performance. These metrics are significant factors in assessing our operating results and profitability and include: (i) throughput volumes; (ii) EBITDA; (iii) distributable cash flow and (iv) operating expenses.

Throughput Volumes

The amount of revenue we generate primarily depends on the volumes of natural gas and condensate that we gather for our Sponsors and is primarily affected by upstream development drilling and production volumes from the natural gas wells connected to our gathering pipelines. Our Sponsors’ willingness to engage in new drilling is determined by a number of factors, the most important of which are the prevailing and projected prices of natural gas and natural gas liquids ("NGLs"), the cost to drill and operate a well, the availability and cost of capital and environmental and government regulations. We generally expect the level of drilling to positively correlate with long-term trends in commodity prices. Similarly, production levels nationally and regionally generally tend to positively correlate with drilling activity.

In order to meet our contractual obligations under our gathering agreements with our Sponsors related to new wells drilled on our dedicated acreage, we will be required to incur capital expenditures to extend our gathering systems and facilities to the new wells they drill. Our Sponsors will be responsible for their proportionate share of the total capital expenditures associated with the ongoing build-out of our midstream systems representing their 25%, 95% and 95% ownership interests in the Anchor, Growth and Additional Systems, respectively. Since our IPO we have reduced our 2015 anticipated capital expenditures in the Growth and Additional systems due to the deferral of certain pipeline system projects driven by our Sponsors' reduced drilling activity, including the Tygart Valley System in West Virginia.

We have secured significant acreage dedications from our Sponsors, which have dedicated to us approximately 516,000 net acres of their jointly owned Marcellus Shale acreage for an initial term of 20 years. In addition to our existing dedicated acreage, our gathering agreements provide that any additional acreage covering the Marcellus Shale that is jointly acquired by our Sponsors in a “dedication area” covering over 7,700 square miles in West Virginia and Pennsylvania will be automatically dedicated to us. We also have the right of first offer (“ROFO”) to provide midstream services to our Sponsors on our ROFO acreage, which currently includes approximately 186,000 net acres of our Sponsors’ jointly owned Marcellus Shale acreage and any additional acreage covering the Marcellus Shale that is jointly acquired by our Sponsors in a “ROFO area” covering over 18,300 square miles in West Virginia and Pennsylvania.

22

Because the production rate of a natural gas well declines over time, we must continually obtain new supplies of natural gas and condensate to maintain or increase the throughput volumes on our midstream systems. Our ability to maintain or increase existing throughput volumes and obtain new supplies of natural gas and condensate are impacted by:

• successful drilling activity by our Sponsors on our dedicated acreage and our ability to fund the capital costs required to connect our gathering systems to new wells;

• our ability to utilize the remaining uncommitted capacity on, or add additional capacity to, our gathering systems;

• the level of work-overs and re-completions of wells on existing pad sites to which our gathering systems are connected;

• our ability to increase throughput volumes on our gathering systems by making outlet connections to existing or new third-party pipelines or other facilities, primarily driven by the anticipated supply of and demand for natural gas;

• the number of new pad sites on our dedicated acreage awaiting lateral connections;

• our ability to identify and execute organic expansion projects to capture incremental volumes from our Sponsors and third parties;

• our ability to compete for volumes from successful new wells in the areas in which we operate outside of our dedicated acreage; and

• our ability to gather natural gas and condensate that has been released from commitments with our competitors.

We actively monitor the activities of producers in the areas served by our gathering systems to pursue new supply opportunities.

EBITDA & Distributable Cash Flow

EBITDA and distributable cash flow are non-GAAP measures that we believe provide information useful to investors in assessing our financial condition and results of operations. For a discussion on how we define EBITDA and distributable cash flow and the supporting reconciliations to their most directly comparable GAAP financial measures, please read “Non-GAAP Financial Measures” below.

Expenses

Operating Expense

We seek to maximize the profitability of our operations in part by minimizing, to the extent appropriate, expenses directly tied to operating our assets. Electrical compression, direct labor costs, ad valorem and property taxes, repair and non-capitalized maintenance costs, integrity management costs, utilities and contract services comprise the most significant portion of our operations and maintenance expense. These expenses generally remain stable across broad ranges of throughput volumes but can fluctuate from period to period depending on the mix of activities performed during that period and the timing of these expenses. We seek to manage our operating expenditures on our midstream systems by scheduling maintenance over time to avoid significant variability in our maintenance expenditures and minimize their impact on our cash flows.

General and Administrative Expense

Since the completion of the IPO, we incur charges for a combination of direct and allocated charges for general and administrative services. Our Predecessor’s general and administrative expense included direct charges for the management and operation of our assets by CONSOL for general and administrative services, such as information technology, engineering, legal, human resources and other financial and administrative services.

Factors Affecting the Comparability of Our Financial Results

Our results of operations may not be comparable to our Predecessor’s historical results of operations for the reasons described below:

Ownership of Our Assets

Our Predecessor’s historical results of operations include all of the results of operations of CONE Gathering on a 100% basis, which includes 100% of the results of our Anchor Systems, Growth Systems and Additional Systems, as well as 100% of the results of certain ancillary midstream assets that CONE Gathering owns. In connection with the completion of the IPO, our Sponsors contributed to us a 75% controlling interest in our Anchor Systems, a 5% controlling interest in our Growth Systems and a 5% controlling interest in our Additional Systems. Consequently, our results of operations following the completion of the IPO reflect less than 100% of the results of our Anchor Systems, Growth Systems and Additional Systems and do not include any results of certain ancillary midstream assets that CONE Gathering owns.

23

Revenues

Our Predecessor’s results of operations reflect gathering revenues based on the same fixed fee per unit of throughput of natural gas it gathered, regardless of the liquids-content of the natural gas, as well as reimbursements for electrically-powered compression costs. Under the gathering agreements with our Sponsors, we receive separate fixed fees for wet gas and dry gas that we gather and another fixed fee per unit of throughput for condensate gathering and handling services at the applicable receipt points. Our Predecessor’s results of operations reflect the remittance of a net condensate price to our Sponsors for the condensate gathering and handling services provided by our Predecessor.

General and Administrative Expenses

Since the completion of the IPO, we incur charges for a combination of direct and allocated charges for general and administrative services. Our Predecessor’s general and administrative expense included direct charges for the management and operation of our assets by CONSOL for general and administrative services, such as information technology, engineering, legal, human resources and other financial and administrative services.

Financing

There are differences in the way we will finance our operations as compared to the way our Predecessor financed its operations. Historically, our Predecessor’s operations were financed as part of our Sponsors’ midstream joint venture operations, and our Predecessor did not record any separate costs associated with financing its operations. In addition, our Predecessor largely relied on internally generated cash flows and capital contributions from our Sponsors to satisfy its capital expenditure requirements.

Our partnership agreement requires that we distribute all of our available cash to our unitholders. As a result, we expect to rely primarily upon external financing sources, including commercial bank borrowings and the issuance of debt and equity securities, to fund our acquisitions and expansion capital expenditures. At September 30, 2015, we had an outstanding balance of $56.5 million and available borrowing capacity of $193.5 million under our $250.0 million revolving credit facility.

Other Factors Impacting Our Business

Based on assumptions made by us and information currently available to us. we expect our business to continue to be affected by the following key factors. To the extent our underlying assumptions about, or interpretations of, available information prove to be incorrect, actual results may vary materially from our expected results.

Our Sponsors’ Drilling and Development Plan

Our operations are primarily dependent upon our Sponsors’ natural gas production on our dedicated acreage in the Marcellus Shale, over which we have no control. Our Sponsors’ have established a drilling and development program on their upstream acreage, including on our dedicated acreage. Our Sponsors primarily rely on us to deliver the midstream infrastructure necessary to accommodate their continuing production growth in the Marcellus Shale. However, our Sponsors’ joint development agreement contains certain mechanisms that may cause their production on our dedicated acreage to be less than we anticipate.

Fluctuations in natural gas and/or NGL prices could affect production rates over time and levels of investment by our Sponsors and third parties in exploration for and development of new natural gas reserves. Persistent low commodity prices may cause our Sponsors or potential third-party customers to delay drilling or shut in production, which would reduce the volumes of natural gas and condensate available for gathering by our midstream systems. If our Sponsors delay drilling or temporarily shut in production due to persistently low commodity prices or for any other reason, we are not assured a certain amount of revenue as our gathering agreements with our Sponsors do not contain minimum volume commitments.

Regulatory Compliance

The regulation of natural gas and condensate gathering and transportation activities by federal and state regulatory agencies has a significant impact on our business. For example, the U.S. Department of Transportation's Pipeline and Hazardous Materials Safety Administration has developed regulations that require pipeline operators to implement integrity management programs, including more frequent inspections and other measures to ensure pipeline safety in high-consequence areas. Our operations are also impacted by new regulations, which have increased the time that it takes to obtain required permits.

Additionally, increased regulation of oil and natural gas producers in our areas of operation, including regulation associated with hydraulic fracturing, could reduce regional supply of oil and natural gas, which would negatively affect throughput on our gathering systems.

Revenue    

Because our Sponsors have established a drilling and development program on our dedicated acreage, our revenue tends to increase with increases in our Sponsors’ production on our dedicated acreage.

Gathering revenue — related party was approximately $53.8 million for the three months ended September 30, 2015 compared to approximately $35.8 million for the three months ended September 30, 2014. The $18.0 million increase was primarily due to a 378 BBtu/d increase in throughput volumes, which was primarily due to a 286 BBtu/d increase in natural gas volumes in our Sponsors’ wet gas and condensate production areas and a 92 BBtu/d increase in natural gas volumes in our Sponsors’ dry gas production area. Of the wet gas and condensate change, 88 BBtu/d was related to the Anchor Systems, 10 BBtu/d was related to the Growth Systems, and 192 BBtu/d was related to the Additional Systems. Of the dry gas change, 65 BBtu/d was related to the Anchor Systems and 33 BBtu/d was related to our Growth and Additional Systems. The remaining volumes were related to assets retained by our Predecessor.

25

Operating Expense

Operating expense is comprised of items directly related to the cost of gathering natural gas at the wellhead and transporting it to interstate pipelines or other local sales points. These costs include items such as electrical compression, repairs and maintenance, supplies, treating and contract services. Despite gathered volumes increasing 49% compared to the prior year quarter, total operating expense remained relatively flat at $12.8 million for the current quarter compared to $12.9 million for the prior year quarter, due primarily to reduced pricing on chemicals and the successful implementation of cost control initiatives by management throughout 2015. Included in operating expense was $4.3 million and $2.9 million of electrical compression in the quarters ended September 30, 2015 and 2014, respectively, that was passed through to the Sponsors.

General and Administrative Expense

General and administrative expense is comprised of direct charges for the management and operation of our assets. Total general and administrative expense was approximately $3.4 million for the three months ended September 30, 2015 compared to approximately $1.7 million for the three months ended September 30, 2014. The $1.7 million increase was primarily due to additional legal and professional fees associated with being a public company.

Depreciation    

Depreciation is recognized on gathering and other equipment on a straight-line basis, with useful lives ranging from 25-40 years. Total depreciation expense was approximately $3.8 million for the three months ended September 30, 2015 compared to approximately $1.8 million for the three months ended September 30, 2014. The increase of $2.0 million was primarily related to an increase in assets placed into service.

Revenue    

Because our Sponsors have established a drilling and development program on our dedicated acreage, our revenue tends to increase with increases in our Sponsors’ production on our dedicated acreage.

Gathering revenue — related party was approximately $144.6 million for the nine months ended September 30, 2015 compared to approximately $87.7 million for the nine months ended September 30, 2014. The $57.0 million increase was primarily due to a 408 BBtu/d increase in throughput volumes, which was primarily due to a 299 BBtu/d increase in natural gas volumes in our Sponsors’ wet gas and condensate production areas and a 109 BBtu/d increase in natural gas volumes in our Sponsors’ dry gas production area. Of the wet gas and condensate change, 134 BBtu/d was related to the Anchor Systems, 8 BBtu/d was related to the Growth Systems, and 161 BBtu/d was related to the Additional and Systems. Of the dry gas change, 73 BBtu/d was related to the Anchor Systems and 41 BBtu/d was related to our Growth and Additional Systems. The remaining volumes were related to assets retained by our Predecessor.

Operating Expense

Operating expense is comprised of items directly related to the cost of gathering natural gas at the wellhead and transporting it to interstate pipelines or other local sales points. These costs include items such as electrical compression, repairs and maintenance, supplies, treating and contract services. Total operating expense was approximately $44.3 million for the nine months ended September 30, 2015 compared to approximately $36.9 million for the nine months ended September 30, 2014. The increase in total operating expense is primarily due to the increase in throughput volumes. Included in operating expense was $11.4 million and $8.6 million of electrical compression in the nine months ended September 30, 2015 and 2014, respectively, that was passed through to the Sponsors.

General and Administrative Expense

General and administrative expense is comprised of direct charges for the management and operation of our assets. Total general and administrative expense was approximately $9.9 million for the nine months ended September 30, 2015 compared to approximately $3.9 million for the nine months ended September 30, 2014, an increase of $6.0 million. The increase was primarily due to additional legal and professional fees associated with being a public company.

Depreciation    

Depreciation is recognized on gathering and other equipment on a straight-line basis, with useful lives ranging from 25-40 years. Total depreciation expense was approximately $10.4 million for the nine months ended September 30, 2015 compared to approximately $5.1 million for the nine months ended September 30, 2014. The increase of $5.3 million was primarily related to an increase in assets placed into service.

Non-GAAP Financial Measures

Adjusted EBITDA

We define adjusted EBITDA as net income (loss) before net interest expense, depreciation and amortization, as adjusted for non-cash items which should not be included in the calculation of distributable cash flow. Adjusted EBITDA is used as a supplemental financial measure by management and by external users of our financial statements, such as investors, industry analysts, lenders and ratings agencies, to assess:

• our operating performance as compared to those of other companies in the midstream energy industry, without regard to financing methods, historical cost basis or capital structure;

• the ability of our assets to generate sufficient cash flow to make distributions to our partners;

• our ability to incur and service debt and fund capital expenditures; and

27

• the viability of acquisitions and other capital expenditure projects and the returns on investment of various investment opportunities.

We believe that the presentation of adjusted EBITDA provides information that is useful to investors in assessing our financial condition and results of operations. The GAAP measures most directly comparable to adjusted EBITDA are net income and net cash provided by operating activities. Adjusted EBITDA should not be considered an alternative to net income, net cash provided by (used in) operating activities or any other measure of financial performance or liquidity presented in accordance with GAAP. Adjusted EBITDA excludes some, but not all, items that affect net income or net cash, and these measures may vary from those of other companies. As a result, adjusted EBITDA as presented below may not be comparable to similarly titled measures of other companies.

Distributable Cash Flow

We define distributable cash flow as adjusted EBITDA less net cash interest paid and maintenance capital expenditures. Distributable cash flow does not reflect changes in working capital balances.

Distributable cash flow is used as a supplemental financial measure by management and by external users of our financial statements, such as investors, industry analysts, lenders and ratings agencies, to assess:

• the ability of our assets to generate cash sufficient to support our indebtedness and make future cash distributions to our unitholders; and

• the attractiveness of capital projects and acquisitions and the overall rates of return on alternative investment opportunities.

We believe that the presentation of distributable cash flow in this report provides information useful to investors in assessing our financial condition and results of operations. The GAAP measures most directly comparable to distributable cash flow are net income and net cash provided by operating activities. Distributable cash flow should not be considered an alternative to net income, net cash provided by operating activities or any other measure of financial performance or liquidity presented in accordance with GAAP. Distributable cash flow excludes some, but not all, items that affect net income or net cash, and these measures may vary from those of other companies. As a result, our distributable cash flow may not be comparable to similarly titled measures of other companies.

Liquidity and Capital Resources

Liquidity and Financing Arrangements

Our principal liquidity requirements are to finance our operations, fund capital expenditures and acquisitions, make cash distributions and satisfy any indebtedness obligations. Our ability to meet these liquidity requirements will depend on our ability to generate cash in the future.

Historically, our principal sources of liquidity have been cash from operations and funding from our Sponsors. While we have historically received funding from our Sponsors, we do not have any formal commitment from our Sponsors, CONE Gathering, our general partner or any of their respective affiliates to fund our cash flow deficits or provide other direct or indirect financial assistance to us following the IPO. We expect our ongoing sources of liquidity to include cash generated from operations, borrowings under our revolving credit facility and, if necessary, the issuance of additional equity or debt securities. We believe that cash generated from these sources will be sufficient to meet our short-term working capital requirements and long-term capital expenditure requirements and to make quarterly cash distributions.

29

Our partnership agreement requires that we distribute all of our available cash to our unitholders. As a result, we expect to rely primarily upon external financing sources, including commercial bank borrowings and the issuance of debt and equity securities, to fund our acquisitions and expansion capital expenditures.

The minimum quarterly distribution of $0.2125 per unit per quarter, which equates to an aggregate distribution of approximately $12.7 million per quarter, or approximately $50.6 million per year, is based on the number of common units, subordinated units and the general partner interest outstanding. We do not have a legal or contractual obligation to pay distributions quarterly or on any other basis at our minimum quarterly distribution rate or at any other rate.

Revolving Credit Facility

On September 30, 2014, we entered into a $250.0 million revolving credit facility, which is available for working capital, capital expenditures, certain acquisitions, distributions, unit repurchases and other lawful partnership purposes. Borrowings under our revolving credit facility bear interest at our option at either:

• the base rate, which will be defined as the highest of (i) the federal funds rate plus 0.50%; (ii) JP Morgan’s prime rate; or (iii) the daily LIBOR rate for a one month interest period plus 1.00%; in each case, plus a margin varying from 0.1250% to 1.00% depending on our most recent consolidated total leverage ratio; or

• the LIBOR rate plus a margin varying from 1.1250% to 2.00%, in each case, depending on our most recent consolidated leverage ratio (as defined in the agreement governing our revolving credit facility) or our credit rating, as the case may be.

Interest on base rate loans is payable quarterly. Interest on LIBOR loans is payable on the last day of each interest period or, in the case of interest periods longer than three months, every three months. The unused portion of our revolving credit facility is subject to a commitment fee ranging from 0.15% to 0.35% per annum depending on our most recent consolidated leverage ratio or our credit rating, as the case may be.

Our revolving credit facility contains covenants and conditions that, among other things, limit our ability to incur or guarantee additional debt, make cash distributions (though there will be an exception for distributions permitted under the partnership agreement, subject to certain customary conditions), incur certain liens or permit them to exist, make certain investments and acquisitions, enter into certain types of transactions with affiliates, merge or consolidate with another company, and transfer, sell or otherwise dispose of assets.

We are also subject to covenants that require us to maintain certain financial ratios. For example, we may not permit the ratio of (i) consolidated total funded debt (as defined in the agreement governing our revolving credit facility) as of the last day of each fiscal quarter to (ii) consolidated EBITDA (as defined in the agreement governing our revolving credit facility) for the four consecutive fiscal quarters ending on the last day of such fiscal quarter to exceed (A) at any time other than during a qualified acquisition period (as defined in the agreement governing our revolving credit facility), 5.0 to 1.0 and (B) during a qualified acquisition period, 5.5 to 1.0. We define this as our consolidated leverage ratio which is calculated as total funded outstanding on our credit facility divided by EBITDA Attributable to General and Limited Partner Ownership Interest in CONE Midstream Partners LP. The consolidated leverage ratio was 0.8 to 1.0 at September 30, 2015. Based on this ratio, the Partnership had the maximum amount of revolving credit available for borrowing at September 30, 2015, of which $56.5 million had been drawn. In addition, we may not permit the ratio of (i) consolidated EBITDA for the four consecutive fiscal quarters ending on the last day of each fiscal quarter to (ii) consolidated interest expense (as defined in the agreement governing our revolving credit facility) for such four consecutive fiscal quarters to be less than 3.0 to 1.0. We define this as our consolidated interest coverage ratio which is calculated as EBITDA Attributable to General and Limited Partner Ownership Interest in CONE Midstream Partners LP divided by total interest charges. The interest coverage ratio was 362.0 to 1.0 at September 30, 2015.

Cash Flows

Net cash provided by operating activities, investing activities and financing activities for the nine months ended September 30, 2015 and 2014 were as follows:

	Nine Months Ended September 30,
(dollars in thousands)	2015			2014			Change
Net cash provided by operating activities:	$	99,268		$	62,363		$	36,905
Net cash used in investing activities:	$	(232,950	)	$	(185,702	)	$	(47,248	)
Net cash provided by financing activities:	$	131,635		$	124,711		$	6,924

Net cash provided by operating activities increased $36.9 million during the nine months ended September 30, 2015 compared to the nine months ended September 30, 2014. The increase was primarily due to an improvement in CONE

30

Midstream Partners LP's consolidated year over year EBITDA of $43.5 million. The remaining cash flow reduction is due to the timing of current asset and liability payments (working capital).

Cash used in investing activities increased $47.2 million due to capital expenditures related to the expansion of our midstream systems, primarily in response to our Sponsors’ growing production on our dedicated acreage in the Marcellus Shale.

Cash provided by financing activities increased $6.9 million. Additional investments from our Sponsors of $24.3 million, proceeds from our revolving credit facility of $25.9 million and the decrease of the distribution of proceeds of $408.0 million were more than offset by cash distributions paid to unitholders of $38.5 million and the decrease of the proceeds from the issuance of common units of $412.7 million.

Capital Expenditures

The midstream energy business is capital intensive, requiring the maintenance of existing gathering systems and other midstream assets and facilities and the acquisition or construction and development of new gathering systems and other midstream assets and facilities. Our partnership agreement requires that we categorize our capital expenditures as either:

• Maintenance capital expenditures, which are cash expenditures (including expenditures for the construction or development of new capital assets or the replacement, improvement or expansion of existing capital assets) made to maintain, over the long term, our operating capacity, operating income or revenue. Examples of maintenance capital expenditures are expenditures to repair, refurbish and replace pipelines, to maintain equipment reliability, integrity and safety and to comply with environmental laws and regulations. In addition, we designate a portion of our capital expenditures to connect new wells to maintain gathering throughput as maintenance capital to the extent such capital expenditures are necessary to maintain, over the long term, our operating capacity, operating income or revenue; or

• Expansion capital expenditures, which are cash expenditures to construct new midstream infrastructure and those expenditures incurred in order to extend the useful lives of our assets, reduce costs, increase revenues or increase system throughput or capacity from current levels, including well connections that increase existing system throughput. Examples of expansion capital expenditures include the construction, development or acquisition of additional gathering pipelines and compressor stations, in each case to the extent such capital expenditures are expected to expand our operating capacity, operating income or revenue. In the future, if we make acquisitions that increase system throughput or capacity, the associated capital expenditures may also be considered expansion capital expenditures.

For the three months ended September 30, 2015, total capital expenditures were $94.7 million on a 100% basis, which includes 100% of the capital expenditures associated with the Anchor Systems, Growth Systems and Additional Systems of which CONE Midstream Partners LP owns a controlling interest of 75%, 5% and 5%, respectively. Total capital expenditures consisted of gathering, compression and processing assets of $88.7 million, land assets of $5.4 million and permitting assets of $0.6 million. The gathering asset expenditures attributable to the Partnership were primarily associated with the construction of new pipeline infrastructure to connect new well pad sites and central receipt points on our Anchor Systems. Approximately $2.3 million of these capital expenditures were maintenance capital expenditures.

For the nine months ended September 30, 2015, total capital expenditures were $232.9 million on a 100% basis, which includes 100% of the capital expenditures associated with the Anchor Systems, Growth Systems and Additional Systems of which CONE Midstream Partners LP owns a controlling interest of 75%, 5% and 5%, respectively. Total capital expenditures consisted of gathering, compression and processing assets of $205.8 million, land assets of $24.2 million and permitting assets of $2.9 million. The gathering asset expenditures attributable to the Partnership were primarily associated with the construction of new pipeline infrastructure to connect new well pad sites and central receipt points on our Anchor Systems. Approximately $6.4 million of these capital expenditures were maintenance capital expenditures.

We anticipate that we will continue to make significant expansion capital expenditures in the future. Consequently, our ability to develop and maintain sources of funds to meet our capital requirements is critical to our ability to meet our growth objectives. We expect that our future expansion capital expenditures will be funded by borrowings under our revolving credit facility and the issuance of debt and equity securities.

Off-Balance Sheet Arrangements

At September 30, 2015, CONE Gathering has $3.6 million of surety bonds outstanding that secure financial obligations for environmental, road maintenance and various other items which are not reflected on the consolidated balance sheet. Since we intend to satisfy the obligations to which the surety bonds relate in the normal course of business, management believes they will expire without being funded.

We do not maintain any other off-balance sheet transactions, arrangements, obligations or other relationships with unconsolidated entities or others that are reasonably likely to have a material current or future effect on our financial condition, changes in financial condition, revenues or expenses, results of operations, liquidity, capital expenditures or capital resources which are not disclosed in the notes to the unaudited consolidated financial statements of this Quarterly Report on Form 10-Q.

Critical Accounting Policies

The Partnership’s critical accounting policies are described in the notes to the consolidated financial statements for the year ended December 31, 2014 contained in the Partnership’s Annual Report on Form 10-K.  Any new accounting policies or updates to existing accounting policies as a result of new accounting pronouncements have been included in the notes to the Partnership’s consolidated financial statements included in this Quarterly Report on Form 10-Q for the period ended September 30, 2015.  The application of the Partnership’s critical accounting policies may require management to make judgments and estimates about the amounts recorded in the consolidated financial statements.  Management uses historical experience and all available information to make these estimates and judgments.  Different amounts could be reported using different assumptions and estimates.

Forward-Looking Statements

This report contains forward-looking statements. Statements that are predictive in nature, that depend upon or refer to future events or conditions or that include the words “believe,” “expect,” “anticipate,” “intend,” “estimate” and other expressions that are predictions of or indicate future events and trends and that do not relate to historical matters identify forward-looking statements.

ITEM 3. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

Commodity Price Risk

We currently generate all of our revenues pursuant to fee-based gathering agreements under which we are paid based on the volumes of natural gas and condensate that we gather and handle, rather than the underlying value of the commodity. Consequently, our existing operations and cash flows have little direct exposure to commodity price risk. However, we are indirectly exposed to commodity price risks if our Sponsors reduce or shut down production due to depressed commodity prices. Although we intend to enter into similar fee-based gathering agreements with new customers in the future, our efforts to negotiate such terms may not be successful.

We may acquire or develop additional midstream assets in a manner that increases our exposure to commodity price risk. Future exposure to the volatility of natural gas, NGL and crude oil prices could have a material adverse effect on our business, financial condition, results of operations, cash flows and ability to make cash distributions to our unitholders.

Interest Rate Risk

In connection with the closing of our IPO on September 30, 2014, we entered into a $250 million revolving credit facility. Assuming our current outstanding balance on the revolving credit facility of $56.5 million, an increase of one percentage point in the interest rates would result in an annual interest expense increase of $0.6 million. As a result, our results of operations, cash flows and financial condition and, consequently, our ability to make cash distributions to our unitholders, could be materially adversely affected by significant increases in interest rates.

Seasonality

Demand for natural gas generally decreases during the spring and fall months and increases during the summer and winter months. However, seasonal anomalies such as mild winters or mild summers sometimes lessen this fluctuation. In addition, certain natural gas users utilize natural gas storage facilities and purchase some of their anticipated winter requirements during the summer. This can also lessen seasonal demand fluctuations. These seasonal anomalies can increase demand for natural gas during the summer and winter months and decrease demand for natural gas during the spring and fall months. With respect to our completed midstream systems, we do not expect seasonal conditions to have a material impact on our throughput volumes. Severe or prolonged winters may, however, impact our ability to complete additional well connections or complete construction projects, which may impact the rate of our growth. In addition, severe winter weather may also impact or slow the ability of our Sponsors to execute their planned drilling and development plans.

ITEM 4. CONTROLS AND PROCEDURES

Evaluation of Disclosure Controls and Procedures

Under the supervision and with the participation of management of the Partnership’s general partner, including the general partner’s Principal Executive Officer and Principal Financial Officer, an evaluation of the Partnership’s disclosure controls and procedures (as defined in Rules 13a-15(e) and 15d-15(e) under the Securities Exchange Act of 1934, as amended (Exchange Act)), was conducted as of the end of the period covered by this report. Based upon this evaluation, the Chief Executive Officer and Chief Financial Officer of the Partnership’s general partner have concluded that the Partnership’s disclosure controls and procedures were effective as of the end of the period covered by this report.

Changes in Internal Control over Financial Reporting

There were no changes in internal control over financial reporting (as such term is defined in Rules 13a-15(f) and 15d-15(f) under the Exchange Act) that occurred during the third quarter of 2015 that have materially affected, or are reasonably likely to materially affect, the Partnership’s internal control over financial reporting.

PART II: OTHER INFORMATION

ITEM 1. LEGAL PROCEEDINGS

Refer to Part I, Item 1. Financial Statements, “Note 10. Commitments and Contingencies,” which is incorporated herein by reference.

ITEM 1A. RISK FACTORS

In addition to the other information set forth in this report, you should carefully consider the risks under the heading “Item 1A. Risk Factors” from our Annual Report on Form 10-K for the year ended December 31, 2014, together with the following risks that have been amended and restated from the prior “Risk Factors” disclosed in the Form 10-K. These risks are not the only risks that we face. Additional risks and uncertainties not currently known to us or that we currently deem to be immaterial also may materially adversely affect our business, financial condition, cash flows or results of operations.

Environmental regulations introduce uncertainty that could adversely impact the market for natural gas with potential short-term and long-term liabilities.

The Federal Endangered Species Act ("ESA") and similar state laws protect species threatened with extinction. Protection of endangered and threatened species may cause us to modify gas well pad siting or pipeline right of ways, or develop and implement species-specific protection and enhancement plans to avoid or minimize impacts to endangered species or their habitats. A number of species indigenous to the areas where we operate are protected under the ESA. Based on species that have been identified and the current application of endangered species laws and regulations, we do not believe that there are any species protected under the ESA or state laws that would materially and adversely affect our ability to gather gas. However, In April 2015 the US Fish and Wildlife Service ("USFWS") announced a Section 4(d) threatened listing final rule for the Northern Long-Eared Bat throughout our operations area. This listing will establish habitat protection for the species but will not prevent the cause of the decline in the population of the Long-Eared bat, which is due to a disease commonly referred to as White Nose Syndrome ("WNS"). This listing could lead to significant timing and critical path hurdles, ultimately limiting the ability to clear timber for construction activities.

In April 2015 the USFWS also proposed the listing of Big Sandy Crayfish and Guyandotte River Crayfish as endangered under the ESA. USFWS has stated that the primary threats to crayfishes throughout their respective ranges are land-disturbing activities that increase erosion and sedimentation, which degrades the stream habitat required by both species. Identified sources of ongoing erosion and sedimentation that occur throughout the ranges of the species include commercial forestry, unpaved roads, gas and oil development, and road construction. This has the potential to disrupt future natural gas activities in Central Appalachia.

In response to a spill by Freedom Industries of crude 4-methylcyclohexanemethanol ("MCHM") to the Elk River in January 2014, West Virginia signed into law Senate Bill 373 (also known as the Above Ground Storage Tank Act), which requires that all above ground storage tanks ("ASTs") be registered with the West Virginia Department of Environmental Protection ("WV DEP") and meet additional requirements. This Act took effect on June 6, 2014. In October 2014, the WV DEP filed a Final Interpretive Rule (47CSR62) addressing initial inspection, certification and spill prevention response plan requirements. On March 14, 2015, the WV Legislature passed Senate Bill 423 to amend the “unintended consequences” of the AST Act on the economy of WV which became effective June 12, 2015. However, with over 4,000 impacted ASTs currently operational in WV and more needed for oil and gas production, this proposed final rule could still have significant cost associated with its requirements. On June 25, 2015 DEP proposed three AST rules to cover establishment of regulatory program, fees, and enforcement authority. DEP plans to issue a final rule to be effective in 2016.

CONSOL Energy, one of our Sponsors, utilizes pipelines extensively for its gas, water, and coal businesses; and as such must obtain permits with associated mitigation from the Army Corps of Engineers ("ACOE") for impacts to streams and wetlands that are unavoidable. In 2013, the EPA issued a draft report entitled Connectivity of Streams and Wetlands to Downstream Waters, which affects a proposed rulemaking that would expand the scope of the Clean Water Act ("CWA") to include previously non-jurisdictional streams, wetlands, and waters, making these areas jurisdictional inter-coastal Waters of the U.S. On June 29, 2015 EPA published the final WotUS rule but a federal appeals court stayed implementation of the rule in October 2015 as legal challenges to the rule are considered. This rulemaking will likely cause states that have jurisdiction over their own waters to make regulatory changes to their already robust regulatory programs and add unwarranted delays to the permitting process and extend review times even further for regulatory agencies already under resourced, and lead to additional mitigation cost and severely limit CONSOL’s and CONE Midstream's ability to avoid regulated jurisdictional waters.

In April 2015, the EPA proposed a CWA regulation (Effluent Limitations Guidelines and Standards for the Oil and Gas Extraction Point Source Category) establishing pretreatment standards that would prohibit the indirect discharge of wastewater

35

from onshore unconventional oil and gas extraction facilities to publicly owned treatment works ("POTWs"). While discharges to POTWs are not currently utilized, unconventional oil and gas extraction wastewater can be generated in large quantities. It is unclear how the newly proposed rule could affect future water use and disposal practices.

Federal and state regulations for horizontal well drilling and well site construction have been proposed and are currently being considered. These regulations could negatively affect our Sponsors financial condition and results of operations. On April 4, 2015 PA published an advanced notice of final rulemaking on revisions to the Environmental Protection Performance Standards at Oil and Gas Well Sites (Chapters 78 and 78a) that could have significant impacts on how oil and natural gas companies currently operate in PA. On June 26, 2015 WV proposed amendments to regulations under 35 WVCSR 8 regarding standards for Horizontal Well Development. In May 2015 OH passed Horizontal Well Site Construction Rules which will become effective in July 2015. OH is also in the process of reviewing and possibly adopting additional developing additional horizontal development rules.

Changes in federal or state income tax laws, particularly in the area of percentage depletion and intangible drilling costs, could cause our Sponsors financial position and profitability to deteriorate.

The passage of legislation or any other similar changes in U.S. federal income tax law could eliminate or postpone certain tax deductions that are currently available with respect to natural gas, oil or coal exploration and development. Any such change could negatively affect our Sponsors financial condition and results of operations.

In February 2012, the PA state legislature passed a new natural gas impact fee in PA, where a substantial portion of our acreage in the Marcellus Shale is located. The legislation imposes an annual fee on natural gas and oil operators for each well drilled for a period of fifteen years. The fee is on a sliding scale set by the Public Utility Commission and is based on two factors: changes in the Consumer Price Index and the average New York Mercantile Exchange’s natural gas prices from the last day of each month. The estimated total fees per well based on today’s current natural gas price is $310,000 over the 15 year period. The passage of this legislation increases the financial burden of our Sponsors on their operations in the Marcellus Shale.

Additionally, legislation has been proposed in OH and PA to introduce a new severance tax on the oil and gas industry. The proposed rates have varied from 2.5 - 7.5 percent and would represent a significant increased financial burden to our Sponsors beyond what is already in place.

Net Income per Limited Partner and General Partner Interest

Earnings Per Share [Abstract]

Net Income per Limited Partner and General Partner Interest

NET INCOME PER LIMITED PARTNER AND GENERAL PARTNER INTEREST

We allocate net income among our general partner and limited partners using the two-class method in accordance with applicable authoritative accounting guidance. Under the two-class method, we allocate net income to our limited partners, our general partner and the holders of our IDRs in accordance with the terms of our partnership agreement. We also allocate any earnings in excess of distributions to our limited partners, our general partner and the holders of the IDRs in accordance with the terms of our partnership agreement. We allocate any distributions in excess of earnings for the period to our general partner and our limited partners based on their respective proportionate ownership interests in us, after taking into account distributions to be paid with respect to the IDRs, as set forth in our partnership agreement.

Diluted net income per limited partner unit reflects the potential dilution that could occur if securities or agreements to issue common units, such as awards under the long-term incentive plan, were exercised, settled or converted into common units.  When it is determined that potential common units resulting from an award subject to performance or market conditions should be included in the diluted net income per limited partner unit calculation, the impact is reflected by applying the treasury stock method. There were 13,258 and 34,940 phantom units included in the calculation of diluted net income per limited partner unit for the respective three and nine months ended September 30, 2015. There were 21,682 phantom units that were not included in the calculation for the three months ended September 30, 2015 because the effect would have been antidilutive.

The following table illustrates the Partnership’s calculation of net income per unit for common and subordinated partner units:

Segment Reporting [Abstract]

Schedule of Operating Revenues and Income from Operations

Operating segments are revenue-producing components of the enterprise for which separate financial information is produced internally and is subject to evaluation by the chief operating decision maker in deciding how to allocate resources.

In order to effectively manage our business we have divided our current midstream assets among three separate categories that we refer to as our “Anchor Systems,” “Growth Systems” and “Additional Systems” based on their relative current cash flows, growth profiles, capital expenditure requirements and the timing of their development.

All of the Partnership’s operating revenues, income from operations and assets are generated or located in the United States.

Under the Jumpstart Our Business Startups Act ("JOBS Act"), for as long as the Partnership remains an “emerging growth company” as defined in the JOBS Act, we may take advantage of certain exemptions from the Securities and Exchange Commission's ("SEC") reporting requirements that are applicable to other public companies that are not emerging growth companies, including not being required to provide an auditor’s attestation report on management’s assessment of the effectiveness of its system of internal control over financial reporting pursuant to Section 404 of the Sarbanes-Oxley Act, reduced disclosure obligations regarding executive compensation in our periodic reports, and exemptions from the requirements of holding a nonbinding advisory vote on executive compensation and seeking unitholder approval of any golden parachute payments not previously approved. We may take advantage of these reporting exemptions until we are no longer an emerging growth company.

The Partnership will remain an emerging growth company for up to five years from the date of our initial public offering, although we will lose that status sooner if:

• we have more than $1.0 billion of revenues in a fiscal year;

• the limited partner interests held by non-affiliates have a market value of more than $700 million; or

• we issue more than $1.0 billion of non-convertible debt over a three-year period.

The JOBS Act also provides that an emerging growth company can delay adopting new or revised accounting standards until such time as those standards apply to private companies. The Partnership irrevocably elected to “opt out” of this exemption and, therefore, is and will be subject to the same new or revised accounting standards as other public companies that are not emerging growth companies.

Principles of Consolidation

The consolidated financial statements include the accounts of CONE Midstream Partners LP and all of its controlled subsidiaries. Transactions between the Partnership and its Sponsors have been identified in the consolidated financial statements as transactions between related parties and are discussed in Note 4.

Use of Estimates

The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets, liabilities, revenues and expenses, and various disclosures. Actual results could differ from those estimates.

Revenue Recognition

Revenues are recognized for the transportation of natural gas and other hydrocarbons based on the delivery of actual volumes transported at a contracted throughput rate. Operating fees received are recorded in gathering revenue — related party in the period the service is performed.

Accounts Receivable

Accounts receivable are recorded at the invoiced amount and do not bear interest. When applicable, we reserve for specific accounts receivable when it is probable that all or a part of an outstanding balance will not be collected, such as customer bankruptcies. Collectability is determined based on terms of sale, credit status of customers and various other circumstances. We regularly review collectability and establish or adjust the allowance as necessary using the specific identification method. Account balances are charged off against the allowance after all means of collection have been exhausted and the potential for recovery is considered remote. There were no reserves for uncollectible amounts in the periods presented.

Inventory

Inventory is stated at the lower of cost or market and consists of pipe purchased for a pipeline project that has been delayed.  The cost is determined primarily under the specific identification method.  The Partnership expects the pipe will be used in an alternative project or sold to a third party.

Property and Equipment

Property and equipment is recorded at cost upon acquisition. Expenditures which extend the useful lives of existing property and equipment are capitalized.

Depreciation of property and equipment is calculated on the straight-line method over the estimated useful lives or lease terms of the assets.

When properties are retired or otherwise disposed, the related cost and accumulated depreciation are removed from the respective accounts and any profit or loss on disposition is recognized as gain or loss. There were no retirements or disposals during the periods presented.

The Partnership evaluates whether long-lived assets have been impaired and determines if the carrying amount of its assets may not be recoverable. For such long-lived assets, impairment exists when the carrying amount of an asset exceeds estimates of the undiscounted cash flows expected to result from the use and eventual disposition of the asset. If the carrying amount of the long-lived asset is not recoverable, based on the estimated future undiscounted cash flows, the impairment loss is measured as the excess of the asset’s carrying amount over its estimated fair value.

Fair value represents the estimated price between market participants to sell an asset in the principal or most advantageous market for the asset, based on assumptions a market participant would make. When warranted, management assesses the fair value of long-lived assets using commonly accepted techniques and may use more than one source in making such assessments. Sources used to determine fair value include, but are not limited to, recent third-party comparable sales, internally developed discounted cash flow analyses and analyses from outside advisors. Significant changes, such as the condition of an asset or management’s intent to utilize the asset generally require management to reassess the cash flows related to long-lived assets. No impairments were identified during the periods presented.

Variable Interest Entities

The Anchor, Growth and Additional Limited Partnerships (the "Limited Partnerships"), which are variable interest entities, are consolidated by CONE Midstream Partners LP through its ownership of CONE Midstream Operating Company LLC. CONE Midstream Operating Company LLC, through its general partner ownership interest in each of the Anchor, Growth and Additional Limited Partnerships, has the power to direct all substantive strategic and day-to-day operational decisions of the Limited Partnerships. CONE Midstream Operating Company LLC is considered to be the primary beneficiary for accounting purposes. 

Environmental Matters

We are subject to various federal, state and local laws and regulations relating to the protection of the environment. Environmental expenditures that relate to current operations are expensed or capitalized as appropriate. Expenditures that relate to an existing condition caused by past operations, and do not contribute to current or future revenue generation, are expensed. Liabilities are recorded when environmental assessments and/or clean-ups are probable, and the costs can be reasonably estimated. At this time, we are unable to assess the timing and/or effect of potential liabilities related to greenhouse gas emissions or other environmental issues. As of September 30, 2015, we had no material environmental matters that required specific disclosure or requiring the recognition of a liability.

Asset Retirement Obligations

We perform an ongoing analysis of asset removal and site restoration costs that we may be required to perform under law or contract once an asset has been permanently taken out of service. We have property and equipment at locations that we own and at sites leased or under right of way agreements. We are under no contractual obligation to remove the assets at locations we own. In evaluating our asset retirement obligation, we review lease agreements, right of way agreements, easements and permits to determine which agreements, if any, require an asset removal and restoration obligation. Determination of the amounts to be recognized is based upon numerous estimates and assumptions, including expected settlement dates, future retirement costs, future inflation rates and the credit-adjusted-risk-free interest rates. We operate and maintain our midstream systems and intend to do so as long as supply and demand for natural gas exists, which we expect for the foreseeable future. Therefore, we believe that we cannot reasonably estimate the asset retirement obligations for our midstream system assets as these assets have indeterminate lives.

Income Taxes

Our operations as a limited partnership, and our Predecessor, as a limited liability company, are treated as partnerships for federal and state income tax purposes, with each partner being separately taxed on its share of the taxable income. Accordingly, no provision for federal or state income taxes has been recorded in the consolidated financial statements.

Cash Distributions

Our partnership agreement requires that we distribute all of our available cash within 45 days after the end of each quarterly period to unitholders of record on the applicable record date. This requirement forms the basis of our cash distribution policy and reflects a basic judgment that our unitholders will be better served by distributing our available cash rather than retaining it because, among other reasons, we believe we will generally finance any expansion capital expenditures from external financing sources. Under our current cash distribution policy, we intend to make a minimum quarterly distribution to the holders of our common units and subordinated units of $0.2125 per unit, or $0.85 per unit on an annualized basis, to the extent we have sufficient available cash after the establishment of cash reserves and the payment of costs and expenses, including the payment of expenses to our general partner. However, other than the requirement in our partnership agreement to distribute all of our available cash each quarter, we have no legal obligation to make quarterly cash distributions in this or any other amount, and the board of directors of our general partner has considerable discretion to determine the amount of our available cash each quarter. In addition, the board of directors of our general partner may change our cash distribution policy at any time, subject to the requirement in our partnership agreement to distribute all of our available cash quarterly.

Generally, our available cash is the sum of (i) all cash on hand at the end of a quarter after the payment of our expenses and the establishment of cash reserves and (ii) if the board of directors of our general partner so determines, all or any portion of additional cash on hand resulting from working capital borrowings made after the end of the quarter.

The following table illustrates the percentage allocations of available cash from operating surplus between the unitholders and our general partner based on the specified target distribution levels. The amounts set forth under “Marginal Percentage Interest in Distributions” are the percentage interests of our general partner and the unitholders in any available cash from operating surplus we distribute up to and including the corresponding amount in the column “Total Quarterly Distribution Per Unit Target Amount.” The percentage interests shown for our unitholders and our general partner for the minimum quarterly distribution are also applicable to quarterly distribution amounts that are less than the minimum quarterly distribution.

The percentage interests set forth below for our general partner include its 2% general partner interest and assume that our general partner has contributed any additional capital necessary to maintain its 2% general partner interest, our general partner has not transferred its incentive distribution rights and there are no arrearages on common units.

			Marginal Percentage Interest in Distributions
Distribution Targets	Total Quarterly Distribution Per Unit Target Amount		Unitholders	General Partner
Minimum Quarterly Distribution		$0.2125	98%	2%
First Target Distribution	Above $0.2125	up to $0.24438	98%	2%
Second Target Distribution	Above $0.24438	up to $0.26563	85%	15%
Third Target Distribution	Above $0.26563	up to $0.31875	75%	25%
Thereafter	Above $0.31875		50%	50%

Subordinated Units

Our partnership agreement provides that, during the subordination period, the common unitholders will have the right to receive distributions of available cash from operating surplus each quarter in an amount equal to $0.2125 per unit, which is defined in our partnership agreement as the minimum quarterly distribution, plus any arrearages in the payment of the minimum quarterly distribution on the common units from prior quarters, before any distributions of available cash from operating surplus may be made on the subordinated units. The practical effect of the subordinated units is to increase the likelihood that, during the subordination period, there will be available cash to be distributed on the common units. The subordination period will end, and the subordinated units will convert to common units, on a one-for-one basis, when certain distribution requirements, as defined in the partnership agreement, have been met.

Subordination Period

Except as described below, the subordination period began on the closing date of the IPO and will extend until the first business day following the distribution of available cash in respect of any quarter beginning after September 30, 2017, that each of the following tests are met:

• distributions of available cash from operating surplus on each of the outstanding common units and subordinated units and the corresponding distributions on the 2% general partner interest equaled or exceeded $0.85 (the annualized minimum quarterly distribution), for each of the three consecutive, non-overlapping four-quarter periods immediately preceding that date;

• the adjusted operating surplus (as defined below) generated during each of the three consecutive, non-overlapping four-quarter periods immediately preceding that date equaled or exceeded the sum of $0.85 (the annualized minimum quarterly distribution) on all of the outstanding common units and subordinated units and the corresponding distributions on the 2% general partner interest during those periods on a fully diluted basis; and

• there are no arrearages in payment of the minimum quarterly distribution on the common units.

Early Termination of the Subordination Period

The subordination period will automatically terminate on the first business day following the distribution of available cash in respect of any quarter, beginning with the quarter ending September 30, 2015, that each of the following tests are met: 

• distributions of available cash from operating surplus on each of the outstanding common units and subordinated units and the corresponding distributions on the 2% general partner interest equaled or exceeded $1.275 (150% of the annualized minimum quarterly distribution), plus the related distributions on the incentive distribution rights, for the four-quarter period immediately preceding that date;

• the adjusted operating surplus (as defined below) generated during the four-quarter period immediately preceding that date equaled or exceeded the sum of (i) $1.275 (150% of the annualized minimum quarterly distribution) on all of the outstanding common units and subordinated units and the corresponding distributions on the 2% general partner interest during that period on a fully diluted basis and (ii) the corresponding distributions on the incentive distribution rights; and

• there are no arrearages in payment of the minimum quarterly distribution on the common units.

Expiration of the Subordination Period

When the subordination period ends, each outstanding subordinated unit will convert into one common unit and will thereafter participate pro rata with the other common units in distributions of available cash.

Adjusted Operating Surplus

Adjusted operating surplus is intended to reflect the cash generated from operations during a particular period and therefore excludes net drawdowns of reserves of cash established in prior periods. Adjusted operating surplus for a period consists of:

• operating surplus generated with respect to that period; less

• any net increase in working capital borrowings with respect to that period; less

• any net decrease in cash reserves for operating expenditures with respect to that period not relating to an operating expenditure made with respect to that period; plus

• any net decrease in working capital borrowings with respect to that period; plus

• any net decrease made in subsequent periods to cash reserves for operating expenditures initially established with respect to that period to the extent such decrease results in a reduction in adjusted operating surplus in subsequent periods; plus

• any net increase in cash reserves for operating expenditures with respect to that period required by any debt instrument for the repayment of principal, interest or premium.

Incentive Distribution Rights ("IDRs")

All of the IDRs are currently held by CONE Midstream GP LLC, our general partner. Incentive distribution rights represent the right to receive an increasing percentage (13.0%, 23.0% and 48.0%) of quarterly distributions of available cash from operating surplus after the minimum quarterly distribution and the target distribution levels described below have been achieved. Our general partner may transfer the IDRs separately from its general partner interest.

The following discussion assumes that our general partner maintains its 2% general partner interest and that our general partner continues to own the IDRs.

If for any quarter:

• we have distributed available cash from operating surplus to the common unitholders and subordinated unitholders in an amount equal to the minimum quarterly distribution; and

• we have distributed available cash from operating surplus on outstanding common units in an amount necessary to eliminate any cumulative arrearages in payment of the minimum quarterly distribution;

then, we will distribute any additional available cash from operating surplus for that quarter among the unitholders and our general partner in the following manner:

• first, 98% to all unitholders, pro rata, and 2% to our general partner, until each unitholder receives a total of $0.24438 per unit for that quarter (the “first target distribution”);

• second, 85% to all unitholders, pro rata, and 15% to our general partner, until each unitholder receives a total of $0.26563 per unit for that quarter (the “second target distribution”);

• third, 75% to all unitholders, pro rata, and 25% to our general partner, until each unitholder receives a total of $0.31875 per unit for that quarter (the “third target distribution”); and

• thereafter, 50% to all unitholders, pro rata, and 50% to our general partner.

Reclassifications

Certain amounts in prior periods have been reclassified to conform to the current reporting classifications with no effect on previously reported net income or partners' capital.

Recent Accounting Pronouncements

In May 2014, the FASB issued 2014-09 "Revenue from Contracts with Customers (Topic 606)". The objective of the amendments in this update is to improve financial reporting by creating common revenue recognition guidance for U.S. GAAP and International Financial Reporting Standards ("IFRS"). The guidance in this update supersedes the revenue recognition requirements in Topic 605, Revenue Recognition, and most industry-specific guidance throughout the Industry Topics of the Codification. The core principle of the guidance is that an entity should recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. An entity should disclose sufficient information, both qualitative and quantitative, to enable users of financial statements to understand the nature, amount, timing, and uncertainty of revenue and cash flows arising from contracts with customers. In August 2015, the FASB issued a standard to delay the effective date by one year. In accordance with this delay, the new standard is effective for annual reporting periods beginning after December 15, 2018, with the option to adopt as early as annual reporting periods beginning after December 15, 2016. We are currently evaluating the method of adoption and impact that this new standard will have on our financial statements.

In April 2015, the FASB issued ASU 2015-06 "Earnings Per Share (Topic 260): Effects on Historical Earnings per Unit of Master Limited Partnership Dropdown Transactions".  ASU 2015-06 specifies that for purposes of calculating historical earnings per unit under the two-class method, the earnings or losses of a transferred business before the date of a dropdown transaction should be allocated entirely to the general partner. In that circumstance, the previously reported earnings per unit of the limited partners, which is typically the earnings per unit measure presented in the financial statements, would not change as a result of the dropdown transaction. This ASU is effective for annual and interim reporting periods beginning after December 15, 2015 and is required to be applied retrospectively. The Partnership believes adoption of this new standard will not have a material impact on the Partnership's financial statements.

In April 2015, the FASB issued ASU 2015-03 "Interest - Imputation of Interest: Simplifying the Presentation of Debt Issuance Costs" ("ASU 2015-3"), which attempted to simplify the presentation of debt issuance costs by requiring that such costs be presented as a deduction from the corresponding debt liability. In August 2015, the FASB issued ASU No. 2015-15 "Interest - Imputation of Interest (Subtopic 835-30): Presentation and Subsequent Measurement of Debt Issuance Costs Associated with Line-of-Credit Arrangements", which clarified ASU 2015-3 as it relates to line-of-credit arrangements. ASU 2015-15 states that the SEC staff would not object to an entity's decision to continue to present debt issuance costs as an asset and subsequently amortize the deferred debt issuance costs ratably over the term of the line-of-credit arrangement, regardless of whether there are any outstanding borrowings on the line-of-credit arrangement. Because this is how the Partnership has historically accounted for debt issuance costs, adoption of this standard will not have any impact on reported results or disclosures.

In February 2015, the FASB issued ASU No. 2015-02, "Consolidation: Amendments to the Consolidation Analysis. ASU 2015-02 changes the analysis that a reporting entity must perform to determine whether it should consolidate certain types of legal entities. The ASU will be effective for annual reporting periods beginning after December 15, 2015, including interim periods therein. The Partnership believes adoption of this new standard will not have a material impact on the Partnership's financial statements.

Significant Accounting Policies (Policies)

9 Months Ended

Sep. 30, 2015

Accounting Policies [Abstract]

Principles of Consolidation

The consolidated financial statements include the accounts of CONE Midstream Partners LP and all of its controlled subsidiaries. Transactions between the Partnership and its Sponsors have been identified in the consolidated financial statements as transactions between related parties and are discussed in Note 4.

Use of Estimates

The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets, liabilities, revenues and expenses, and various disclosures. Actual results could differ from those estimates.

Revenue Recognition

Revenues are recognized for the transportation of natural gas and other hydrocarbons based on the delivery of actual volumes transported at a contracted throughput rate. Operating fees received are recorded in gathering revenue — related party in the period the service is performed.

Accounts Receivable

Accounts receivable are recorded at the invoiced amount and do not bear interest. When applicable, we reserve for specific accounts receivable when it is probable that all or a part of an outstanding balance will not be collected, such as customer bankruptcies. Collectability is determined based on terms of sale, credit status of customers and various other circumstances. We regularly review collectability and establish or adjust the allowance as necessary using the specific identification method. Account balances are charged off against the allowance after all means of collection have been exhausted and the potential for recovery is considered remote. There were no reserves for uncollectible amounts in the periods presented.

Inventory

Inventory is stated at the lower of cost or market and consists of pipe purchased for a pipeline project that has been delayed.  The cost is determined primarily under the specific identification method.  The Partnership expects the pipe will be used in an alternative project or sold to a third party.

Property and Equipment

Property and equipment is recorded at cost upon acquisition. Expenditures which extend the useful lives of existing property and equipment are capitalized.

Depreciation of property and equipment is calculated on the straight-line method over the estimated useful lives or lease terms of the assets.

When properties are retired or otherwise disposed, the related cost and accumulated depreciation are removed from the respective accounts and any profit or loss on disposition is recognized as gain or loss. There were no retirements or disposals during the periods presented.

The Partnership evaluates whether long-lived assets have been impaired and determines if the carrying amount of its assets may not be recoverable. For such long-lived assets, impairment exists when the carrying amount of an asset exceeds estimates of the undiscounted cash flows expected to result from the use and eventual disposition of the asset. If the carrying amount of the long-lived asset is not recoverable, based on the estimated future undiscounted cash flows, the impairment loss is measured as the excess of the asset’s carrying amount over its estimated fair value.

Fair value represents the estimated price between market participants to sell an asset in the principal or most advantageous market for the asset, based on assumptions a market participant would make. When warranted, management assesses the fair value of long-lived assets using commonly accepted techniques and may use more than one source in making such assessments. Sources used to determine fair value include, but are not limited to, recent third-party comparable sales, internally developed discounted cash flow analyses and analyses from outside advisors. Significant changes, such as the condition of an asset or management’s intent to utilize the asset generally require management to reassess the cash flows related to long-lived assets. No impairments were identified during the periods presented.

Variable Interest Entities

The Anchor, Growth and Additional Limited Partnerships (the "Limited Partnerships"), which are variable interest entities, are consolidated by CONE Midstream Partners LP through its ownership of CONE Midstream Operating Company LLC. CONE Midstream Operating Company LLC, through its general partner ownership interest in each of the Anchor, Growth and Additional Limited Partnerships, has the power to direct all substantive strategic and day-to-day operational decisions of the Limited Partnerships. CONE Midstream Operating Company LLC is considered to be the primary beneficiary for accounting purposes. 

Environmental Matters

We are subject to various federal, state and local laws and regulations relating to the protection of the environment. Environmental expenditures that relate to current operations are expensed or capitalized as appropriate. Expenditures that relate to an existing condition caused by past operations, and do not contribute to current or future revenue generation, are expensed. Liabilities are recorded when environmental assessments and/or clean-ups are probable, and the costs can be reasonably estimated. At this time, we are unable to assess the timing and/or effect of potential liabilities related to greenhouse gas emissions or other environmental issues. As of September 30, 2015, we had no material environmental matters that required specific disclosure or requiring the recognition of a liability.

Asset Retirement Obligations

We perform an ongoing analysis of asset removal and site restoration costs that we may be required to perform under law or contract once an asset has been permanently taken out of service. We have property and equipment at locations that we own and at sites leased or under right of way agreements. We are under no contractual obligation to remove the assets at locations we own. In evaluating our asset retirement obligation, we review lease agreements, right of way agreements, easements and permits to determine which agreements, if any, require an asset removal and restoration obligation. Determination of the amounts to be recognized is based upon numerous estimates and assumptions, including expected settlement dates, future retirement costs, future inflation rates and the credit-adjusted-risk-free interest rates. We operate and maintain our midstream systems and intend to do so as long as supply and demand for natural gas exists, which we expect for the foreseeable future. Therefore, we believe that we cannot reasonably estimate the asset retirement obligations for our midstream system assets as these assets have indeterminate lives.

Income Taxes

Our operations as a limited partnership, and our Predecessor, as a limited liability company, are treated as partnerships for federal and state income tax purposes, with each partner being separately taxed on its share of the taxable income. Accordingly, no provision for federal or state income taxes has been recorded in the consolidated financial statements.

Subordinated Units and Incentive Distribution Rights

Subordinated Units

Our partnership agreement provides that, during the subordination period, the common unitholders will have the right to receive distributions of available cash from operating surplus each quarter in an amount equal to $0.2125 per unit, which is defined in our partnership agreement as the minimum quarterly distribution, plus any arrearages in the payment of the minimum quarterly distribution on the common units from prior quarters, before any distributions of available cash from operating surplus may be made on the subordinated units. The practical effect of the subordinated units is to increase the likelihood that, during the subordination period, there will be available cash to be distributed on the common units. The subordination period will end, and the subordinated units will convert to common units, on a one-for-one basis, when certain distribution requirements, as defined in the partnership agreement, have been met.

Subordination Period

Except as described below, the subordination period began on the closing date of the IPO and will extend until the first business day following the distribution of available cash in respect of any quarter beginning after September 30, 2017, that each of the following tests are met:

• distributions of available cash from operating surplus on each of the outstanding common units and subordinated units and the corresponding distributions on the 2% general partner interest equaled or exceeded $0.85 (the annualized minimum quarterly distribution), for each of the three consecutive, non-overlapping four-quarter periods immediately preceding that date;

• the adjusted operating surplus (as defined below) generated during each of the three consecutive, non-overlapping four-quarter periods immediately preceding that date equaled or exceeded the sum of $0.85 (the annualized minimum quarterly distribution) on all of the outstanding common units and subordinated units and the corresponding distributions on the 2% general partner interest during those periods on a fully diluted basis; and

• there are no arrearages in payment of the minimum quarterly distribution on the common units.

Early Termination of the Subordination Period

The subordination period will automatically terminate on the first business day following the distribution of available cash in respect of any quarter, beginning with the quarter ending September 30, 2015, that each of the following tests are met: 

• distributions of available cash from operating surplus on each of the outstanding common units and subordinated units and the corresponding distributions on the 2% general partner interest equaled or exceeded $1.275 (150% of the annualized minimum quarterly distribution), plus the related distributions on the incentive distribution rights, for the four-quarter period immediately preceding that date;

• the adjusted operating surplus (as defined below) generated during the four-quarter period immediately preceding that date equaled or exceeded the sum of (i) $1.275 (150% of the annualized minimum quarterly distribution) on all of the outstanding common units and subordinated units and the corresponding distributions on the 2% general partner interest during that period on a fully diluted basis and (ii) the corresponding distributions on the incentive distribution rights; and

• there are no arrearages in payment of the minimum quarterly distribution on the common units.

Expiration of the Subordination Period

When the subordination period ends, each outstanding subordinated unit will convert into one common unit and will thereafter participate pro rata with the other common units in distributions of available cash.

Adjusted Operating Surplus

Adjusted operating surplus is intended to reflect the cash generated from operations during a particular period and therefore excludes net drawdowns of reserves of cash established in prior periods. Adjusted operating surplus for a period consists of:

• operating surplus generated with respect to that period; less

• any net increase in working capital borrowings with respect to that period; less

• any net decrease in cash reserves for operating expenditures with respect to that period not relating to an operating expenditure made with respect to that period; plus

• any net decrease in working capital borrowings with respect to that period; plus

• any net decrease made in subsequent periods to cash reserves for operating expenditures initially established with respect to that period to the extent such decrease results in a reduction in adjusted operating surplus in subsequent periods; plus

• any net increase in cash reserves for operating expenditures with respect to that period required by any debt instrument for the repayment of principal, interest or premium.

Incentive Distribution Rights ("IDRs")

All of the IDRs are currently held by CONE Midstream GP LLC, our general partner. Incentive distribution rights represent the right to receive an increasing percentage (13.0%, 23.0% and 48.0%) of quarterly distributions of available cash from operating surplus after the minimum quarterly distribution and the target distribution levels described below have been achieved. Our general partner may transfer the IDRs separately from its general partner interest.

Reclassifications

Certain amounts in prior periods have been reclassified to conform to the current reporting classifications with no effect on previously reported net income or partners' capital.

Recent Accounting Pronouncements

In May 2014, the FASB issued 2014-09 "Revenue from Contracts with Customers (Topic 606)". The objective of the amendments in this update is to improve financial reporting by creating common revenue recognition guidance for U.S. GAAP and International Financial Reporting Standards ("IFRS"). The guidance in this update supersedes the revenue recognition requirements in Topic 605, Revenue Recognition, and most industry-specific guidance throughout the Industry Topics of the Codification. The core principle of the guidance is that an entity should recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. An entity should disclose sufficient information, both qualitative and quantitative, to enable users of financial statements to understand the nature, amount, timing, and uncertainty of revenue and cash flows arising from contracts with customers. In August 2015, the FASB issued a standard to delay the effective date by one year. In accordance with this delay, the new standard is effective for annual reporting periods beginning after December 15, 2018, with the option to adopt as early as annual reporting periods beginning after December 15, 2016. We are currently evaluating the method of adoption and impact that this new standard will have on our financial statements.

In April 2015, the FASB issued ASU 2015-06 "Earnings Per Share (Topic 260): Effects on Historical Earnings per Unit of Master Limited Partnership Dropdown Transactions".  ASU 2015-06 specifies that for purposes of calculating historical earnings per unit under the two-class method, the earnings or losses of a transferred business before the date of a dropdown transaction should be allocated entirely to the general partner. In that circumstance, the previously reported earnings per unit of the limited partners, which is typically the earnings per unit measure presented in the financial statements, would not change as a result of the dropdown transaction. This ASU is effective for annual and interim reporting periods beginning after December 15, 2015 and is required to be applied retrospectively. The Partnership believes adoption of this new standard will not have a material impact on the Partnership's financial statements.

In April 2015, the FASB issued ASU 2015-03 "Interest - Imputation of Interest: Simplifying the Presentation of Debt Issuance Costs" ("ASU 2015-3"), which attempted to simplify the presentation of debt issuance costs by requiring that such costs be presented as a deduction from the corresponding debt liability. In August 2015, the FASB issued ASU No. 2015-15 "Interest - Imputation of Interest (Subtopic 835-30): Presentation and Subsequent Measurement of Debt Issuance Costs Associated with Line-of-Credit Arrangements", which clarified ASU 2015-3 as it relates to line-of-credit arrangements. ASU 2015-15 states that the SEC staff would not object to an entity's decision to continue to present debt issuance costs as an asset and subsequently amortize the deferred debt issuance costs ratably over the term of the line-of-credit arrangement, regardless of whether there are any outstanding borrowings on the line-of-credit arrangement. Because this is how the Partnership has historically accounted for debt issuance costs, adoption of this standard will not have any impact on reported results or disclosures.

In February 2015, the FASB issued ASU No. 2015-02, "Consolidation: Amendments to the Consolidation Analysis. ASU 2015-02 changes the analysis that a reporting entity must perform to determine whether it should consolidate certain types of legal entities. The ASU will be effective for annual reporting periods beginning after December 15, 2015, including interim periods therein. The Partnership believes adoption of this new standard will not have a material impact on the Partnership's financial statements.

Distributions Made to Limited Liability Company (LLC) Member, by Distribution [Table Text Block]

Our partnership agreement requires that we distribute all of our available cash within 45 days after the end of each quarterly period to unitholders of record on the applicable record date. This requirement forms the basis of our cash distribution policy and reflects a basic judgment that our unitholders will be better served by distributing our available cash rather than retaining it because, among other reasons, we believe we will generally finance any expansion capital expenditures from external financing sources. Under our current cash distribution policy, we intend to make a minimum quarterly distribution to the holders of our common units and subordinated units of $0.2125 per unit, or $0.85 per unit on an annualized basis, to the extent we have sufficient available cash after the establishment of cash reserves and the payment of costs and expenses, including the payment of expenses to our general partner. However, other than the requirement in our partnership agreement to distribute all of our available cash each quarter, we have no legal obligation to make quarterly cash distributions in this or any other amount, and the board of directors of our general partner has considerable discretion to determine the amount of our available cash each quarter. In addition, the board of directors of our general partner may change our cash distribution policy at any time, subject to the requirement in our partnership agreement to distribute all of our available cash quarterly.

Generally, our available cash is the sum of (i) all cash on hand at the end of a quarter after the payment of our expenses and the establishment of cash reserves and (ii) if the board of directors of our general partner so determines, all or any portion of additional cash on hand resulting from working capital borrowings made after the end of the quarter.

DESCRIPTION OF BUSINESS, INITIAL PUBLIC OFFERING AND BASIS OF PRESENTATION

Description of Business

CONE Midstream Partners LP (the “Partnership”) is a master limited partnership formed in May 2014 by CONSOL Energy Inc. (NYSE: CNX) (“CONSOL”) and Noble Energy, Inc. (NYSE: NBL) (“Noble Energy”), whom we refer to collectively as our Sponsors, to own, operate, develop and acquire natural gas gathering and other midstream energy assets to service our Sponsors’ production in the Marcellus Shale in Pennsylvania and West Virginia. Our assets include natural gas gathering pipelines and compression and dehydration facilities, as well as condensate gathering, collection, separation and stabilization facilities.

In order to effectively manage our business we have divided our current midstream assets among three separate categories that we refer to as our “Anchor Systems,” “Growth Systems” and “Additional Systems” based on their relative current cash flows, growth profiles, capital expenditure requirements and the timing of their development.

• Our Anchor Systems include our midstream systems that generate the substantial majority of our current cash flows and that we expect to drive our growth over the near term as we increase average throughput on these systems from our Sponsors’ growing production.

• Our Growth Systems include our high-growth, developing gathering systems that will require substantial expansion capital expenditures over the next several years, the substantial majority of which will be funded by our Sponsors in proportion to their retained ownership interest.

• Our Additional Systems include several gathering systems primarily located in the wet gas regions of our Sponsors' dedicated acreage that we expect will generate stable cash flows and require lower levels of expansion capital investment over the next several years.

On September 30, 2014, the Partnership closed its initial public offering ("IPO") of common units representing limited partner interests. The Partnership's general partner is CONE Midstream GP LLC (the "general partner"), a wholly owned subsidiary of CONE Gathering LLC ("CONE Gathering"). CONE Gathering, a Delaware limited liability company, is a joint venture formed by our Sponsors in September 2011 and represents the predecessor for accounting purposes (the "Predecessor") of CONE Midstream Partners LP. References in these consolidated financial statements to “our partnership,” “we,” “our,” “us” or like terms, when used for periods prior to the IPO, refer to CONE Gathering. References in these consolidated financial statements to “our partnership,” “we,” “our,” “us” or like terms, when used for periods beginning at or following the IPO, refer collectively to the Partnership and its consolidated subsidiaries. For periods prior to the IPO, the accompanying consolidated financial statements and related notes include the assets, liabilities and results of operations of CONE Gathering.

In order to maintain operational flexibility, our operations are conducted through, and our operating assets are owned by, our operating subsidiaries. However, neither we nor our operating subsidiaries have any employees. Our general partner has the sole responsibility for providing the personnel necessary to conduct our operations, whether through directly hiring employees or by obtaining the services of personnel employed by our Sponsors or others. All of the personnel that conduct our business are employed or contracted by our general partner and its affiliates, including our Sponsors, but we sometimes refer to these individuals as our employees because they provide services directly to us.

Initial Public Offering

On September 30, 2014, the Partnership closed its IPO of 20,125,000 common units at a price to the public of $22.00 per unit, which included 2,625,000 common units issued pursuant to the underwriters' exercise in full of their over-allotment option. The Partnership’s common units are listed on the New York Stock Exchange under the ticker symbol “CNNX.”

Concurrent with the closing of the IPO, CONE Gathering contributed to the Partnership a 75% controlling interest in the Anchor Systems, a 5% controlling interest in the Growth Systems and a 5% controlling interest in the Additional Systems. In exchange for CONE Gathering's contribution of assets and liabilities to the Partnership, CONE Gathering received:

• through its ownership of our general partner, a continuation of a 2% general partner interest in the partnership;

• 9,038,121 common units and 29,163,121 subordinated units, representing an aggregate 64.2% limited partner interest in the Partnership (the common and subordinated units were subsequently distributed to the Sponsors);

• through its ownership of our general partner, all of the Partnerships' incentive distribution rights; and

• an aggregate cash distribution of $408.0 million.

Basis of Presentation

The accompanying unaudited consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States ("GAAP"). To conform to these accounting principles, management makes estimates and assumptions that affect the amounts reported in the consolidated financial statements and the notes thereto. These estimates are evaluated on an ongoing basis, utilizing historical experience and other methods considered reasonable under the particular circumstances. Although these estimates are based on management’s best available knowledge at the time, changes in facts and circumstances or discovery of new facts or circumstances may result in revised estimates. Actual results may differ from these estimates. Effects on the Partnership’s business, financial position and results of operations resulting from revisions to estimates are recognized when the facts that give rise to the revision become known.

The balance sheet at December 31, 2014 has been derived from the audited financial statements at that date but does not include all of the information and footnotes required by GAAP for complete financial statements.

Segment Information

SEGMENT INFORMATION

Operating segments are revenue-producing components of the enterprise for which separate financial information is produced internally and is subject to evaluation by the chief operating decision maker in deciding how to allocate resources.

In order to effectively manage our business we have divided our current midstream assets among three separate categories that we refer to as our “Anchor Systems,” “Growth Systems” and “Additional Systems” based on their relative current cash flows, growth profiles, capital expenditure requirements and the timing of their development.

All of the Partnership’s operating revenues, income from operations and assets are generated or located in the United States.

Schedule of Target Distributions

The following table illustrates the percentage allocations of available cash from operating surplus between the unitholders and our general partner based on the specified target distribution levels. The amounts set forth under “Marginal Percentage Interest in Distributions” are the percentage interests of our general partner and the unitholders in any available cash from operating surplus we distribute up to and including the corresponding amount in the column “Total Quarterly Distribution Per Unit Target Amount.” The percentage interests shown for our unitholders and our general partner for the minimum quarterly distribution are also applicable to quarterly distribution amounts that are less than the minimum quarterly distribution.

The percentage interests set forth below for our general partner include its 2% general partner interest and assume that our general partner has contributed any additional capital necessary to maintain its 2% general partner interest, our general partner has not transferred its incentive distribution rights and there are no arrearages on common units.

Revolving Credit Facility

REVOLVING CREDIT FACILITY

In connection with the closing of our IPO on September 30, 2014, we entered into a credit facility agreement which provides for a $250 million unsecured five year revolving credit facility that matures on September 30, 2019. Our revolving credit facility is available for working capital, capital expenditures, certain acquisitions, distributions, unit repurchases and other lawful partnership purposes. Borrowings under our revolving credit facility will bear interest at our option at either:

• the base rate, which is defined as the highest of (i) the federal funds rate plus 0.50%; (ii) JP Morgan’s prime rate; or (iii) the daily LIBOR rate for a one month interest period plus 1.00%; in each case, plus a margin varying from 0.1250% to 1.00% depending on our most recent consolidated total leverage ratio; or

• the LIBOR rate plus a margin varying from 1.1250% to 2.00%, in each case, depending on our most recent consolidated leverage ratio (as defined in the agreement governing our revolving credit facility) or our credit rating, as the case may be.

Interest on base rate loans is payable quarterly. Interest on LIBOR loans is payable on the last day of each interest period or, in the case of interest periods longer than three months, every three months. The unused portion of our revolving credit facility is subject to a commitment fee ranging from 0.15% to 0.35% per annum depending on our most recent consolidated leverage ratio or our credit rating, as the case may be.

Our revolving credit facility contains covenants and conditions that, among other things, limit our ability to incur or guarantee additional debt, make cash distributions (though there will be an exception for distributions permitted under the partnership agreement, subject to certain customary conditions), incur certain liens or permit them to exist, make certain investments and acquisitions, enter into certain types of transactions with affiliates, merge or consolidate with another company, and transfer, sell or otherwise dispose of assets. We are also subject to covenants that require us to maintain certain financial ratios. For example, we may not permit the ratio of (i) consolidated total funded debt (as defined in the agreement governing our revolving credit facility) as of the last day of each fiscal quarter to (ii) consolidated EBITDA (as defined in the agreement governing our revolving credit facility) for the four consecutive fiscal quarters ending on the last day of such fiscal quarter to exceed (A) at any time other than during a qualified acquisition period (as defined in the agreement governing our revolving credit facility), 5.00 to 1.00 and (B) during a qualified acquisition period, 5.50 to 1.00. In addition, we may not permit the ratio of (i) consolidated EBITDA for the four consecutive fiscal quarters ending on the last day of each fiscal quarter to (ii) consolidated interest expense (as defined in the agreement governing our revolving credit facility) for such four consecutive fiscal quarters to be less than 3.00 to 1.00. We were in compliance with all relevant covenants at September 30, 2015.

The outstanding balance of our revolving credit facility and interest rates on the amounts drawn from our revolver consist of the following:

	September 30, 2015				December 31, 2014
(dollars in thousands, except percentages)	Debt		Interest Rate (1)		Debt		Interest Rate (1)
Credit Facility	$	56,500	3.75	%	$	31,300	3.75	%

⁽¹⁾ At September 30, 2015 and December 31, 2014, borrowings accrued interest at JP Morgan’s prime rate. The average interest rate for the three and nine months period ended September 30, 2015 were 2.36% and 3.03%, respectively.

As of September 30, 2015, we had outstanding debt issuance costs of $0.7 million which were incurred as part of the issuance of our credit facility and are being amortized in interest expense through September 30, 2019, which is the maturity date of the credit facility.

Related Party Transactions [Abstract]

Related Party

RELATED PARTY

In the ordinary course of business, the Partnership has transactions with related parties that result in affiliate transactions. Related parties during each of the periods presented included CONSOL and certain of its subsidiaries and Noble Energy, to whom we provide natural gas gathering and compression services.

Transactions with related parties, other than certain transactions with CONSOL and Noble Energy related to administrative services, were conducted on terms which management believes are comparable to those with unrelated parties. We believe such costs would not have been materially different had they been calculated on a stand-alone basis.

Charges for services from CONSOL included in operating expenses — related party were $8.1 million and $6.0 million for the three months ended September 30, 2015 and 2014 and $22.1 million and $18.6 million for the nine months ended September 30, 2015 and 2014, respectively. There were no charges from Noble Energy included in operating expenses — related party for the three and nine months ended September 30, 2015 and 2014.

During the nine months ended September 30, 2015, CONSOL purchased $2.2 million of supply inventory from the Partnership, none of which occurred in the quarter ended September 30, 2015. Purchases of supply inventory from a CONSOL subsidiary were $1.1 million for the three months ended September 30, 2014 and $3.6 million for the nine months ended September 30, 2014 and were included in operating expenses — related party.

Additionally, charges by each Sponsor included in general and administrative expense - related party consisted of the following:

(dollars in thousands)	Three Months Ended   September 30,				Nine Months Ended   September 30,
	2015		2014		2015		2014

Noble Energy	135		—		411		—
Total General and Administrative Expense — Related Party	$	2,413	$	1,599	$	6,385	$	2,957

Omnibus Agreement

Concurrent with closing the IPO, we entered into an omnibus agreement with CONSOL, Noble Energy, CONE Gathering and our general partner that addresses the following matters:

• our payment of an annual administrative support fee, initially in the amount of $0.6 million (prorated for the first year of service), for the provision of certain services by CONSOL and its affiliates;

• our payment of an annual administrative support fee, initially in the amount of approximately $0.6 million (pro rated for the first year of service), for the provision of certain executive services by CONSOL and its affiliates;

• our payment of an annual administrative support fee, initially in the amount of approximately $0.2 million (pro rated for the first year of service), for the provision of certain executive services by Noble Energy and its affiliates;

• our obligation to reimburse our Sponsors for all other direct or allocated costs and expenses incurred by our Sponsors in providing general and administrative services (which reimbursement is in addition to certain expenses of our general partner and its affiliates that are reimbursed under our partnership agreement);

• our right of first offer to acquire (i) CONE Gathering’s retained interests in each of our Anchor Systems, Growth Systems and Additional Systems, (ii) CONE Gathering’s other ancillary midstream assets and (iii) any additional midstream assets that CONE Gathering develops; and

• an indemnity from CONE Gathering for liabilities associated with the use, ownership or operation of our assets, including environmental liabilities, to the extent relating to the period of time prior to the closing of the IPO; and our obligation to indemnify CONE Gathering for events and conditions associated with the use, ownership or operation of our assets that occur after the closing of the IPO, including environmental liabilities.

So long as CONE Gathering controls our general partner, the omnibus agreement will remain in full force and effect. If CONE Gathering ceases to control our general partner, either party may terminate the omnibus agreement, provided that the indemnification obligations will remain in full force and effect in accordance with their terms.

Operational Services Agreement

Concurrent with closing of the IPO, we entered into an operational services agreement with CONSOL under which CONSOL provides certain operational services to us in support of our gathering pipelines and dehydration, treating and compressor stations and facilities, including routine and emergency maintenance and repair services, routine operational activities, routine administrative services, construction and related services and such other services as we and CONSOL may mutually agree upon from time to time. CONSOL will prepare and submit for our approval a maintenance, operating and capital budget on an annual basis. CONSOL will submit actual expenditures for reimbursement on a monthly basis and we will reimburse CONSOL for any direct third-party costs actually incurred by CONSOL in providing these services.

The operational services agreement has an initial term of 20 years and will continue in full force and effect unless terminated by either party at the end of the initial term or any time thereafter by giving not less than six months’ prior notice to the other party of such termination. CONSOL may terminate the operational services agreement if (1) we become insolvent, declare bankruptcy or take any action in furtherance of, or indicating our consent to, approval of, or acquiescence in, a similar proceeding or (2) upon not less than 180 days notice. We may immediately terminate the agreement (1) if CONSOL becomes insolvent, declares bankruptcy or takes any action in furtherance of, or indicating its consent to, approval of, or acquiescence in, a similar proceeding, (2) upon a finding of CONSOL’s willful misconduct or gross negligence that has had a material adverse effect on any of our gathering pipelines and dehydration, treating and compressor stations and facilities or our business or (3) CONSOL is in material breach of the operational services agreement and fails to cure such default within 45 days.

Under the operational services agreement, CONSOL will indemnify us from any claims, losses or liabilities incurred by us, including third-party claims, arising from CONSOL’s performance of the agreement to the extent caused by CONSOL’s gross negligence or willful misconduct. We will indemnify CONSOL from any claims, losses or liabilities incurred by CONSOL, including any third-party claims, arising from CONSOL’s performance of the agreement, except to the extent such claims, losses or liabilities are caused by CONSOL’s gross negligence or willful misconduct.

Gathering Agreements

CNX Gas Gathering Agreement

On September 30, 2014, in connection with the closing of the IPO, the Partnership entered into a Gathering Agreement (the “CNX Gas Gathering Agreement”) by and between the Partnership, as gatherer, and CNX Gas Company LLC (“CNX Gas”), a wholly owned subsidiary of CONSOL, as shipper. Under the CNX Gas Gathering Agreement, CNX Gas (i) dedicated to the Partnership for natural gas midstream services all of its existing acres and any acres acquired in the future, in each case, that are jointly owned with Noble Energy to the extent covering the Marcellus Shale in the dedication area and (ii) granted the Partnership a right of first offer to provide natural gas midstream services with respect to all of its existing acres and any acres acquired in the future, in each case, that are jointly owned with Noble Energy to the extent covering the Marcellus Shale in the right of first offer area.

The CNX Gas Gathering Agreement commenced on September 30, 2014 and has an initial term of 20 years. Under the CNX Gas Gathering Agreement, if the Partnership fails to timely complete the construction of the facilities necessary to provide midstream services to CNX Gas’ dedicated acreage or has an uncured default of any of the Partnership’s material obligations that has caused an interruption in the Partnership’s services for more than 90 days, the affected acreage will be permanently released from the Partnership’s dedication. Also, after the fifth anniversary of the CNX Gas Gathering Agreement, if CNX Gas drills a well that is located more than a certain distance from the Partnership’s current gathering system (and not included in the detailed drilling plan provided by CNX Gas and Noble Energy) and a third-party gatherer offers a lower cost of services, then the acreage associated with such well will be permanently released from the Partnership’s dedication.

Under the CNX Gas Gathering Agreement, the Partnership charges a fee based on the type and scope of midstream services provided. For the services provided (a) with respect to natural gas that does not require downstream processing, the Partnership receives a fee of $0.40 per MMBtu, (b) with respect to the natural gas that requires downstream processing, the Partnership receives a fee of $0.55 per MMBtu, except in the Pittsburgh International Airport and Moundsville (Marshall County, West Virginia) areas, where the fee is $0.275 per MMBtu and (c) with respect to condensate, the Partnership receives a fee of $5.00 per bbl in the Majorsville area and $2.50 per bbl in the Moundsville area.

NBL Gas Gathering Agreement

On September 30, 2014, in connection with the closing of the IPO, the Partnership entered into a Gathering Agreement (the “NBL Gas Gathering Agreement”) by and between the Partnership, as gatherer, and Noble Energy, as shipper. Under the NBL Gas Gathering Agreement, Noble Energy (i) dedicated to the Partnership for natural gas midstream services all of its existing acres and any acres acquired in the future, in each case, that are jointly owned with CNX Gas to the extent covering the Marcellus Shale in the dedication area and (ii) granted the Partnership a right of first offer to provide natural gas midstream services with respect to all of its existing acres and any acres acquired in the future, in each case, that are jointly owned with CNX Gas to the extent covering the Marcellus Shale in the right of first offer area.

The NBL Gas Gathering Agreement commenced on September 30, 2014 and has an initial term of 20 years. Under the NBL Gas Gathering Agreement, if the Partnership fails to timely complete the construction of the facilities necessary to provide midstream services to Noble Energy’s dedicated acreage or has an uncured default of any of the Partnership’s material obligations that has caused an interruption in the Partnership’s services for more than 90 days, the affected acreage will be permanently released from the Partnership’s dedication. Also, after the fifth anniversary of the NBL Gas Gathering Agreement, if Noble Energy drills a well that is located more than a certain distance from the Partnership’s current gathering system (and not included in the detailed drilling plan provided by CNX Gas and Noble Energy) and a third-party gatherer offers a lower cost of services, then the acreage associated with such well will be permanently released from the Partnership’s dedication.

Under the NBL Gas Gathering Agreement, the Partnership charges a fee based on the type and scope of midstream services provided. For the services provided (a) with respect to natural gas that does not require downstream processing, the Partnership receives a fee of $0.40 per MMBtu, (b) with respect to the natural gas that requires downstream processing, the Partnership receives a fee of $0.55 per MMBtu, except in the Pittsburgh International Airport and Moundsville (Marshall County, West Virginia) areas, where the fee is $0.275 per MMBtu and (c) with respect to condensate, the Partnership receives a fee of $5.00 per bbl in the Majorsville area and $2.50 per bbl in the Moundsville area.

Employee Secondment Agreement

We entered into an employee secondment agreement, effective September 8, 2014, with Noble Energy. Pursuant to the employee secondment agreement, an employee of Noble Energy is seconded to us to provide investor relations and similar functions. We will reimburse Noble Energy for allocable salary, benefits, insurance, payroll taxes and other employment expenses related to the seconded employee.

Under the CONE Midstream Partners LP 2014 Long-Term Incentive Plan (our “LTIP”), our general partner may issue long-term equity based awards to directors, officers and employees of our general partner or its affiliates, or to any consultants, affiliates of our general partner or other individuals who perform services for us. These awards will be intended to compensate the recipients thereof for their continued service during the vesting period based on the performance of our common units and align their long-term interests with those of our unitholders. We will be responsible for the cost of awards granted under our LTIP and all determinations with respect to awards to be made under our LTIP will be made by the board of directors of our general partner or any committee thereof that may be established for such purpose or by any delegate of the board of directors or such committee, subject to applicable law, which we refer to as the plan administrator.

The LTIP limits the number of units that may be delivered pursuant to vested awards to 5,800,000 common units, subject to proportionate adjustment in the event of unit splits and similar events. Common units subject to awards that are canceled, forfeited, withheld to satisfy exercise prices or tax withholding obligations or otherwise terminated without delivery of the common units will be available for delivery pursuant to other awards.

Since the IPO, the Partnership's general partner has granted 33,697 equity-based phantom units at a weighted average fair value of $19.98 that vest over periods of continued service with the Partnership. The value of the phantom units will be paid in common units or an amount of cash equal to the fair market value of a unit based on the grant date. Management intends to settle any vested phantom units in common units. The Partnership accounts for phantom units as equity awards and records compensation expense based on the fair value of the awards at their grant date fair value. Based on the vesting schedules of all awards, the Partnership recognized $0.1 million and $0.3 million of compensation expense for the three and nine months ended September 30, 2015, respectively, which is included in general and administrative expense - related party in the consolidated statements of operations.
