Memorial Production Partners LP Announces Second Quarter 2013 Results,

Updated Commodity Hedge Positions and Full-Year 2013 Guidance

HOUSTON, TEXAS, August 7, 2013—Memorial Production Partners LP (NASDAQ: MEMP) announced today its operating and financial results for the three and six months ended June 30, 2013. In addition, MEMP provided an update of its commodity hedge positions presented in the Hedge Summary Table below along with previously announced full-year 2013 guidance.

Key Second Quarter 2013 Highlights:

“MEMP continues to execute on its strategy of acquiring and developing mature, long-lived oil and gas properties. Since January of this year, we have announced two acquisitions for a total of $806 million and we continue to deliver strong operational results,” said John Weinzierl, Chairman, President and Chief Executive Officer of Memorial Production Partners GP LLC, the general partner of MEMP. “These acquisitions add to a great asset base of conventional, low risk oil and gas production as well as enhance our scale in our core area of East Texas and add geographic diversity through the Permian Basin and the Rockies. Operationally, we had a very good second quarter as we grew our production, lowered operating costs and increased our distribution coverage ratio.”

Review of Second Quarter 2013⁽¹⁾

Acquisitions Update

As previously announced on July 15, 2013, MEMP signed definitive agreements to acquire certain oil and natural gas properties in the Permian Basin, East Texas, and the Rockies, from its sponsor, Memorial Resource Development LLC, and affiliates of Natural Gas Partners for an aggregate purchase price of approximately $606 million, subject to customary purchase price adjustments. The transaction will have an effective date of July 1, 2013 and is expected to close in October 2013. Acquisition highlights include:

Hedging Update

As part of the transaction, MEMP will acquire commodity hedges that cover approximately 72% of acquired PDP volumes through 2015 (82% through 2014). In addition, MEMP will acquire interest rate hedges for a notional principal amount of $11.5 million extending through June 2014 at a fixed annual LIBOR rate of 0.5%. Consistent with its hedging policy, MEMP has layered on incremental commodity hedges that, together with the acquired hedges, cover up to 85% of projected production volumes related to this acquisition through 2018. The acquired and incremental commodity hedges represent total gas volumes of 29 Bcf for the period 2013 – 2018 at a weighted average fixed price of $4.26; total oil volumes of 3.8 MMBbls for the period 2013 – 2018 at a weighted average fixed price of $84.67; and 91,800 Bbls of NGLs for the period 2013 – 2014 at an average fixed price of $36.27.

The following table, pro forma for the transaction, reflects the percentage volumes of MEMP’s production covered by commodity derivative contracts and the average fixed or floor prices at which production is hedged. The targeted average net production estimate represents the production required to reach the lower boundary of the annual production range in MEMP’s 2013 full-year guidance. All of MEMP’s hedges are costless, fixed price swaps and collars.

Previously Announced Full-Year 2013 Guidance

The following guidance included in this press release is subject to the cautionary statements and limitations described under the “Forward-Looking Statements” caption at the end of this press release. MEMP’s full-year 2013 guidance is based on assumptions of capital expenditure levels and the assumption that market demand and prices for oil and natural gas will continue at levels that allow for economic production of these products. It also reflects the impact of forecasted growth capital spending and assumes the completion of the pending acquisition announced on July 15, 2013. The guidance includes the results related to our acquisitions from affiliates from the effective date of July 1, 2013 forward. However, for financial reporting purposes, we will be required to include results related to our acquisitions from affiliates for all periods the assets were under common control. A summary of the guidance, assuming no additional acquisitions, is presented below:

These estimates reflect management’s best judgment based on current expectations about the future and anticipated market conditions based upon both stated and unstated assumptions and other factors. Although management believes such estimates to be reasonable, they are inherently uncertain and involve a number of risks that are beyond MEMP’s control. The aforementioned guidance for 2013 does not reflect the pre-effective date impact of common control revisions. Actual conditions and assumptions may change over the course of the year.

Financial Update

Total debt outstanding as of June 30, 2013 was $439.0 million, including $39.0 million of debt under MEMP’s $1.0 billion multi-year revolving credit facility with a borrowing base of $480.0 million. As of June 30, 2013, MEMP’s liquidity of $447.2 million consisted of $6.2 million of available cash and $441.0 million of available borrowing capacity. As of August 1, 2013, MEMP had $418.0 million of availability under its revolver, which management believes will provide the financial flexibility to continue pursuing MEMP’s acquisition growth strategy.

Second Quarter 2013 Cash Distribution

As announced on July 19, 2013, the board of directors of MEMP’s general partner approved and declared a cash distribution of $0.5125 per unit for the second quarter of 2013. This distribution represents an annualized rate of $2.05 per unit. The distribution will be paid on August 12, 2013 to unitholders of record as of the close of business on August 1, 2013.

Forward-Looking Statements

This press release may include “forward-looking statements.” All statements, other than statements of historical facts, included in this press release that address activities, events or developments that MEMP expects, believes or anticipates will or may occur in the future are forward-looking statements. Terminology such as “will”, “expect”, “plan”, “project”, “intend”, “estimate”, “believe”, “target”, “potential”, the negative of such terms or other comparable terminology often identify forward-looking statements. These statements are based on certain assumptions made by MEMP based on its experience and perception of historical trends, current conditions, expected future developments and other factors it believes are appropriate in

the circumstances. Such statements are subject to a number of assumptions, risks and uncertainties, many of which are beyond the control of MEMP, which may cause MEMP’s actual results to differ materially from those implied or expressed by the forward-looking statements. Please read MEMP’s filings with the SEC, which are available on MEMP’s Investor Relations website at http://investor.memorialpp.com/sec.cfm or on the SEC’s website at http://www.sec.gov, for a discussion of risks and uncertainties that could cause actual results to differ from those in such forward-looking statements. You are cautioned not to place undue reliance on these forward-looking statements, which speak only as of the date of this press release. All forward-looking statements are qualified in their entirety by this cautionary statement. MEMP undertakes no obligation and does not intend to update these forward-looking statements to reflect events or circumstances occurring after this press release.

The SEC permits oil and gas companies, in their filings with the SEC, to disclose only proved, probable and possible reserves that meet the SEC’s definitions for such terms. Estimates of reserves in this press release are based on economic assumptions with regard to commodity prices that differ from the prices required by the SEC (historical 12 month average) to be used in calculating reserves estimates prepared in accordance with SEC definitions and guidelines. In addition, the estimates of reserves in this press release were prepared by our internal reserve engineers and are based on various assumptions, including assumptions related to oil and natural gas prices as discussed above, drilling and operating expenses, capital expenditures, taxes and availability of funds, which may differ materially from the estimates that were used in MEMP’s 2012 Annual Report on Form 10-K.

Use of Non-GAAP Financial Measures

This press release and accompanying schedules include the non-GAAP financial measures of Adjusted EBITDA and Distributable Cash Flow. The accompanying schedules provide a reconciliation of these non-GAAP financial measures to their most directly comparable financial measure calculated and presented in accordance with GAAP. MEMP’s non-GAAP financial measures should not be considered as alternatives to GAAP measures such as net income, operating income, net cash flows provided by operating activities or any other measure of financial performance calculated and presented in accordance with GAAP. MEMP’s non-GAAP financial measures may not be comparable to similarly-titled measures of other companies because they may not calculate such measures in the same manner as MEMP does.

Adjusted EBITDA. MEMP defines Adjusted EBITDA as net income or loss, plus interest expense; net operating cash flow from acquisitions and divestitures, effective date through closing date; income tax expense; depreciation, depletion and amortization; impairment of goodwill and long-lived assets; accretion of asset retirement obligations; unrealized losses on commodity derivative contracts; losses on sale of assets; unit-based compensation expenses; exploration costs; acquisition related costs; amortization of investment premium; and other non-routine items, less interest income; income tax benefit; unrealized gains on commodity derivative contracts; gains on sale of assets and other non-routine items. Adjusted EBITDA is commonly used as a supplemental financial measure by management and external users of MEMP’s financial statements, such as investors, research analysts and rating agencies, to assess: (1) the financial performance of its assets without regard to financing methods, capital structures or historical cost basis; (2) the ability of its assets to generate cash sufficient to pay interest, support MEMP’s indebtedness and make distribution on its units; and (3) the viability of projects and the overall rates of return on alternative investment opportunities. Since Adjusted EBITDA excludes some, but not all, items that affect net income or loss and because these measures may vary among other companies, the Adjusted EBITDA data presented in this press release may not be comparable to similarly titled measures of other companies. The GAAP measure most directly comparable to Adjusted EBITDA is net cash flows provided by operating activities.

Distributable Cash Flow. MEMP defines distributable cash flow as Adjusted EBITDA, less cash income taxes; cash interest expense; and estimated maintenance capital expenditures. Management compares the distributable cash flow MEMP generates to the cash distributions it expects to pay MEMP’s partners. Using this metric, management computes MEMP’s distribution coverage ratio. Distributable cash flow is an important non-GAAP financial measure for MEMP’s limited partners since it serves as an indicator of MEMP’s success in providing a cash return on investment. Specifically, this financial measure indicates to investors whether or not MEMP is generating cash flows at a level that can sustain or support an increase in its quarterly cash distributions. Distributable cash flow is also a quantitative standard used by the investment community with respect to publicly traded partnerships because the value of a partnership unit is, in part, measured by its yield, which is based on the amount of cash distributions a partnership can pay to a unitholder. The GAAP measure most directly comparable to distributable cash flow is net cash flows provided by operating activities.
