Legacy Reserves 8-K/A Report of Independent Auditor

Exhibit 99.1

Report of Independent Auditor

Board of Directors and Unitholders

Legacy Reserves LP

Midland, Texas

We have audited the accompanying combined statement of revenues and direct operating expenses of the oil and natural gas properties and related natural gas gathering and processing assets (together the “Anadarko Acquisitions”), as defined in Note 1, acquired on July 31, 2015 by Legacy Reserves LP for the year ended December 31, 2014 and the related notes to the combined statement of revenues and direct operating expenses.

Management’s Responsibility for the Financial Statement

Management is responsible for the preparation and fair presentation of the combined statement of revenues and direct operating expenses in accordance with accounting principles generally accepted in the United States of America; this includes the design, implementation, and maintenance of internal control relevant to the preparation and fair presentation of the combined statement of revenues and direct operating expenses that is free from material misstatement, whether due to fraud or error.

Auditor’s Responsibility

Our responsibility is to express an opinion on the combined statement of revenues and direct operating expenses based on our audit. We conducted our audit in accordance with auditing standards generally accepted in the United States of America. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the combined statement of revenues and direct operating expenses is free from material misstatement.

An audit involves performing procedures to obtain audit evidence about the amounts and disclosures in the financial statement. The procedures selected depend on the auditor’s judgment, including the assessment of the risks of material misstatement of the financial statement, whether due to fraud or error. In making those risk assessments, the auditor considers internal control relevant to the entity’s preparation and fair presentation of the financial statement in order to design audit procedures that are appropriate in the circumstances, but not for the purpose of expressing an opinion on the effectiveness of the internal controls of the Anadarko Acquisitions. Accordingly, we express no such opinion. An audit also includes evaluating the appropriateness of accounting policies used and the reasonableness of significant accounting estimates made by management, as well as evaluating the overall presentation of the financial statement.

We believe that the audit evidence we have obtained is sufficient and appropriate to provide a basis for our audit opinion.

Opinion

In our opinion, the combined statement of revenues and direct operating expenses referred to above presents fairly, in all material respects, the revenues and direct operating expenses of the Anadarko Acquisitions for the year ended December 31, 2014, in conformity with accounting principles generally accepted in the United States of America.

Emphasis of Matter

The accompanying combined statement of revenues and direct operating expenses was prepared for the purpose of complying with the rules and regulations of the Securities and Exchange Commission for inclusion in Legacy Reserves LP's Form 8-K/A and is not intended to be a complete presentation of the results of the operations of the Anadarko Acquisitions. Our opinion is not modified with respect to this matter.

NOTES TO COMBINED STATEMENTS OF REVENUES AND DIRECT OPERATING EXPENSES

(1) Basis of Presentation

The accompanying combined financial statements present the revenues and direct operating expenses of (1) 100% of the issued and outstanding limited liability company membership interests in Dew Gathering LLC, which owns directly and indirectly natural gas gathering and processing assets in Anderson, Freestone, Houston, Leon, Limestone and Robertson Counties, Texas (the "WGR Acquisition") acquired pursuant to a Membership Interest Purchase and Sale Agreement (the "WGR Purchase Agreement") dated July 3, 2015 among WGR Operating LP ("WGR"), and Legacy Reserves Operating LP, a Delaware limited partnership and a wholly owned subsidiary of Legacy Reserves LP ("Legacy"), and (2) various oil and natural gas properties and associated exploration and production assets (the "Anadarko E&P Acquisition," together with the WGR Acquisition, the "Anadarko Acquisitions") acquired pursuant to the Purchase and Sale Agreement (together with the "WGR Purchase Agreement," the "Agreements") dated July 3, 2015 among Anadarko E&P Onshore LLC ("Anadarko") and Legacy, for the year ended December 31, 2014 and the six months ended June 30, 2015 and 2014. The WGR Acquisition membership interests were purchased by Legacy on July 31, 2015, for a net purchase price of $96.7 million. The Anadarko E&P Acquisition properties were purchased by Legacy on July 31, 2015, for a net purchase price of $328.1 million. As the acquisitions were made from entities under common control, the accounts of the Anadarko Acquisitions have been presented on a combined basis.

The accompanying combined statements of revenues and direct operating expenses of the Anadarko Acquisitions do not include indirect general and administrative expenses, interest expense, depreciation, depletion and amortization, or any provision for income taxes. Legacy's management believes historical expenses of this nature incurred by WGR and Anadarko associated with the properties are not indicative of the costs to be incurred by Legacy.

Revenues in the accompanying combined statements of revenues and direct operating expenses are recognized based on the Anadarko Acquisitions' share of any given period's production multiplied by the contract price received for the period. The direct operating expenses are recognized on the accrual basis and consist of the direct costs of operating the Anadarko Acquisitions including production taxes, lifting costs, gathering, well repair and well workover costs. Direct costs do not include general corporate overhead.

Historical financial information reflecting financial position, results of operations, and cash flows of the Anadarko Acquisitions is not presented because it would be impractical and costly to obtain since such financial information was not historically prepared by WGR or Anadarko. Other assets acquired and liabilities assumed were not material. In addition, the Anadarko Acquisitions were a part of a larger enterprise prior to the acquisition by Legacy, and representative amounts of indirect general and administrative expenses, depreciation, depletion and amortization, interest and other indirect costs were not necessarily allocated to the Anadarko Acquisitions, nor would such allocated historical costs be relevant to future operations of the Anadarko Acquisitions. The historical combined statements of revenues and direct operating expenses of the Anadarko Acquisitions are presented in order to substantially comply with the rules and regulations of the Securities and Exchange Commission (the "SEC") for businesses acquired.

The preparation of combined financial statements in conformity with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that affect the reported amounts of revenue and expenses during the reporting period. Actual results could differ from those estimates.

(2) Subsequent Events

Legacy has evaluated subsequent events through October 14, 2015, the date of the accompanying combined statements of revenue and direct operating expenses were available to be issued. There were no material subsequent events that required recognition or additional disclosure in the accompanying combined statements of revenue and direct operating expenses.

(3) Supplemental Financial Information for Oil and Natural Gas Producing Activities (Unaudited)

The following reserve estimates have been prepared by Legacy's internal petroleum engineer as of December 31, 2014 and 2013. The reserve estimates have been prepared in compliance with the SEC rules and accounting standards based on the 12-month un-weighted first-day-of-the-month average prices as of December 31, 2014 and 2013, with appropriate adjustments by property for location, quality, gathering and marketing adjustments.

(a) Reserve Quantity Information

Proved reserves are estimated quantities of crude oil and natural gas which geological and engineering data demonstrate with reasonable certainty to be recoverable in future years from known reservoirs under existing economic and operating conditions. Proved developed reserves are those which are expected to be recovered through existing wells with existing equipment and operating methods.

Below are the net quantities of total proved reserves and proved developed reserves of the Anadarko Acquisitions. An analysis of the change in estimated quantities of reserves, all of which are located within the United States, is presented below.

	Oil (MBbls)(1)		NGL (MBbls)(1)	Natural Gas (MMcf)(1)		Total (MBoe)
Total Proved Reserves:
Balance, December 31, 2013	4		—	467,322		77,891
Revisions of previous estimates due to price	15		—	51,741		8,639
Production	(6	)	—	(27,416	)	(4,575	)
Balance, December 31, 2014	13		—	491,647		81,955
Proved Developed Reserves:
December 31, 2013	4		—	467,322		77,891
December 31, 2014	13		—	491,647		81,955

(1) Due to the lack of prior year reserve studies, Legacy prepared a reserve study for the most recent period presented and computed reserves for prior periods using historical production amounts.

(b) Standardized Measure of Discounted Future Net Cash Flows Relating to Proved Oil and Natural Gas Reserves

The standardized measure of discounted future net cash flows relating to proved oil and natural gas reserves ("Standardized Measure") is a disclosure requirement under Accounting Standards Codification 932-235. The Standardized Measure does not purport to be, nor should it be interpreted to present, the fair value of the proved oil and natural gas reserves of the Anadarko Acquisitions. An estimate of fair value would also take into account, among other things, the recovery of reserves not presently classified as proved, the value of unproved properties, and consideration of expected future economic and operating conditions. The estimates of future cash flows and future production and development costs are based on the 12-month un-weighted first-day-of-the-month average prices as of December 31, 2014 and 2013, for oil and natural gas, estimated future production of proved reserves and estimated future production and development costs of proved reserves, based on current costs and economic conditions. The estimated future net cash flows are then discounted at a rate of 10%. No deduction has been made for general and administrative expenses, interest expense, depreciation, depletion and amortization or federal or state income taxes.

The Standardized Measure relating to proved oil and natural gas reserves are presented below:

	December 31, 2014
	(In thousands)
Future production revenues	$	1,996,871
Future costs:
Production	(772,201		)
Development	—
Future net cash flows before income taxes	1,224,670
10% annual discount for estimated timing of cash flows	(717,930		)
Standardized measure of discounted net cash flows	$	506,740

The standardized measure is based on the following oil and natural gas prices realized over the life of the properties at the wellhead as of the following date:

	December 31, 2014
Oil (per Bbl)	$	91.48
Natural Gas (per MMBtu)	$	4.35

Changes in the Standardized Measure relating to proved oil and natural gas reserves is as follows:

	Year ended December 31, 2014
	(In thousands)
Increase (decrease):
Sales, net of production costs	$	(79,865	)
Net change in sales prices, net of production costs	173,905
Accretion of discount	3,268
Net increase	97,308
Standardized measure of discounted future net cash flows:
Beginning of period	409,432
End of period	$	506,740

Estimates of economically recoverable oil and natural gas reserves and of future net revenues are based upon a number of variable factors and assumptions, all of which are to some degree speculative and may vary considerably from actual results. Therefore, actual production, revenues, development and operating expenditures may not occur as estimated. The reserve data are estimates only, are subject to many uncertainties and are based on data gained from production histories and on assumptions as to geologic formations, reservoir behavior, equipment condition and other matters. Actual quantities of oil and natural gas produced in the future may differ materially from the amounts estimated.
