QR Energy Announces Third Quarter 2013 Results, Full-Year Outlook and Increased Borrowing Base to $950 Million

HOUSTON, TX—(Marketwired – November 6, 2013) – QR Energy, LP (“QRE” or “QR Energy”) (NYSE: QRE) announced today its operating and financial results for the third quarter of 2013 and provided fourth quarter and full-year guidance.

Highlights for the Third Quarter 2013

Note: Adjusted EBITDA, Distributable Cash Flow and Distribution Coverage Ratio are non-GAAP measures. Please see the definitions of these measures and the reconciliation to the most comparable measures calculated in accordance with GAAP in the “Non-GAAP Reconciliation” section of this press release.

Chief Executive Officer Alan L. Smith commented on the third quarter results, “Our team did a great job executing the game plan of maximizing performance from existing assets, managing costs and assimilating the 2013 East Texas Acquisition assets into our portfolio. The result of these efforts is evident in our increased distribution coverage ratio compared to the second quarter of 2013. For the remainder of the year, we will continue to enhance production by targeting low-risk, oil-weighted capital projects, remain focused on managing operating expenses, and actively pursue accretive acquisition opportunities that fit our investment criteria of lower decline assets.”

Results for the Third Quarter 2013

Borrowing Base Increase

On October 15, 2013, QR Energy’s borrowing base was increased by its lenders from $900 million to $950 million. This increase was a result of the recent 2013 East Texas Acquisition in August 2013 and positive performance revisions in the first half of the year.

As of November 1, 2013, QR Energy had $600 million outstanding under its revolving credit facility, not including $23.5 million of letters of credit outstanding, resulting in $326.5 million of borrowing availability. The next scheduled borrowing base redetermination under the Credit Agreement is May 1, 2014.

Cash Distribution

On November 14, 2013, QR Energy will pay a cash distribution attributable to the third quarter of 2013 of $0.4875 per unit for all outstanding common units. This represents an annualized distribution of $1.95 per common unit.

Guidance

The guidance set forth below is subject to all cautionary statements and limitations described below and under the “Forward-Looking Statements” section of this press release. In addition, estimates for QR Energy’s future production volumes are based on, among other things, 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. The production, transportation and marketing of oil and natural gas are extremely complex and are subject to disruption due to transportation and processing availability, mechanical failure, human error, weather and numerous other factors. Estimates are based on certain other assumptions, such as well performance, which may vary significantly from QR Energy’s assumptions. Operating costs, which include major maintenance costs, vary in response to changes in prices of services and materials used in the operation of properties and the amount of maintenance required. Operating costs, including taxes, utilities and service company costs, move directionally with increases and decreases in commodity prices and QR Energy cannot fully predict such future commodity prices or operating costs. Capital expenditures are based on current expectations as to the level of capital expenditures that will be justified based upon the other assumptions set forth below as well as expectations about other operating and economic factors not set forth below. The guidance set forth below does not constitute any form of guarantee, assurance or promise that the matters indicated will actually be achieved. Rather, the guidance simply sets forth QR Energy’s best estimate today for these matters. Estimates are based upon current expectations about the future and based upon both stated and unstated assumptions. Actual conditions and assumptions may change over the course of the year.

Consolidated Statements of Operations

Note: Please see the financial statements and related footnotes in QR Energy’s 10-Q, as filed with the SEC. Adjusted EBITDA and Distributable Cash Flow are non-GAAP measures.

Consolidated Balance Sheet

Note: Please see the financial statements and related footnotes in QR Energy’s 10-Q, as filed with the SEC.

Non-GAAP Reconciliation

QR Energy defines Adjusted EBITDA as net income from which it adds or subtract net interest expense (including gains and losses on interest rate derivative contracts), depreciation, depletion and amortization, accretion of asset retirement obligations, gains or losses due to effects of change in prices on natural gas imbalances, net gains or losses on commodity derivative contracts, net cash received or paid on the settlement of commodity derivative contracts, income tax expense or benefit, other income or expense, interest expense, impairments, non-

cash general and administrative expense and acquisition and transaction costs, non-cash pension and postretirement expense or credit, and beginning with the third quarter 2013, noncontrolling interest amounts attributable to each of these items, which revert the calculation to the Adjusted EBITDA attributable QR Energy. Prior period results have been revised to conform to the current presentation.

QR Energy defines Distributable Cash Flow as Adjusted EBITDA less cash interest expense (including cash received or paid on interest rate derivative contracts), distributions on its preferred units, payments to its general partner in respect of its management incentive fee and estimated maintenance capital expenditures, which is calculated based on our estimate of the capital required to maintain QR Energy’s current production for five years, on average. This estimate is made at least annually and whenever an event occurs that is likely to result in a material adjustment to the amount of our maintenance capital expenditures, such as a major acquisition or the introduction of new governmental regulations that will impact our business.

QR Energy defines the Distribution Coverage Ratio for a given quarter as the ratio of Distributable Cash Flow per outstanding unit (including general partner units and Class B units and excluding preferred units) to the actual cash distribution payable per outstanding unit (including general partner units and Class B units and excluding preferred units). Holders of the preferred units may elect to convert the preferred units into common units at any time after October 3, 2013, or sooner upon QR Energy’s achievement of certain trading price criteria. Please see QR Energy’s 10-K for a more fulsome description of the terms of the preferred units.

Adjusted EBITDA, Distributable Cash Flow and the Distribution Coverage Ratio are used by management of QR Energy to provide additional information related to the performance of QR Energy’s business. Adjusted EBITDA provides information about the cash flow generated by our assets, without regard to financing methods or historical cost basis and the ability of our assets to generate sufficient cash to pay interest costs and support our indebtedness. Distributable Cash Flow and the Distribution Coverage Ratio provide information comparing cash flows generated by us to cash distributions we expect to pay to our unitholders and indicates to investors whether or not we are generating cash flow at a level that can sustain or support an increase in our quarterly distribution rates. In addition, Adjusted EBITDA, Distributable Cash Flow and the Distribution Coverage Ratio are quantitative standards used by external users of our financial statements such as investors, research analysts and others to assess QR Energy’s performance and liquidity without regard to capital structure. Adjusted EBITDA, Distributable Cash Flow and the Distribution Coverage Ratio are not presentations made in accordance with GAAP. Because Adjusted EBITDA, Distributable Cash Flow and the Distribution Coverage Ratio exclude some, but not all, items that affect net income and are defined differently by different companies in our industry, our definitions may not be comparable to similarly titled measures of other companies. Adjusted EBITDA,

Distributable Cash Flow and the Distribution Coverage Ratio have important limitations as analytical tools, and you should not consider them in isolation, or as a substitute for net income, operating income, cash flow from operating activities or any other measure of financial performance or liquidity presented in accordance with GAAP.
