LRR Energy, L.P. Announces 2012 Year End Results

Houston, Texas (March 7, 2013) - LRR Energy, L.P. (NYSE: LRE) (“LRR Energy”) announced today its operating and financial results for the three months and year ended December 31, 2012.

Selected Financial and Operating Information

Our financial statements for the year ended December 31, 2012, have been recast as if we had owned the assets acquired on June 1, 2012, from Lime Rock Resources since our initial public offering, as the transaction was between entities under common control.  A summary of selected financial and operating information follows.  For consolidated financial statements, please see the accompanying tables on pages 7-9.

(1)         Non-GAAP financial measure. See reconciliation of non-GAAP financial measures on page 10.

Full year 2012 production of 6,303 Boe/d was in line with our public guidance.  Fourth quarter 2012 production of 5,935 Boe/d was generally consistent with our internal forecast, albeit slightly lower. An unexpected compressor failure at our Pecos Slope field in late November 2012 negatively impacted fourth quarter production by approximately 35 Boe/d. The compressor was back in service in mid February 2013.

Proved Reserves

As of December 31, 2012, LRR Energy had 27.9 MMBoe of estimated proved reserves, of which approximately 85% were proved developed reserves.  Our reserves are 53% natural gas and 47% oil and NGLs as measured by volume as of December 31, 2012.  These estimates were calculated using the unweighted arithmetic average first-day-of-the-month closing price for each month of 2012.  The average trailing twelve-month index prices were $94.71/Bbl for NYMEX-WTI and $2.76/MMBtu for NYMEX-Henry Hub natural gas.  For NGL pricing, a differential is applied to the $94.71/Bbl average trailing twelve-month index price for oil.  As of December 31, 2012, the standardized measure of our estimated proved reserves was $325.2 million.

Recent Events

On January 3, 2013, LRR Energy closed its previously announced acquisition of oil and natural gas properties in the Mid-Continent region in Oklahoma from its sponsor, Lime Rock Resources for a purchase price of $21.0 million, subject to customary purchase price adjustments.  In addition, as part of the transaction, LRE acquired in the money commodity hedge contracts valued at approximately $1.8 million as of the closing date.  LRE funded the acquisition with borrowings under its revolving credit facility.  As of March 6, 2013, LRE had $205 million of outstanding borrowings under its revolving credit facility and $50 million of outstanding borrowings under its term loan.  LRE currently has $45 million available under its credit facility which management believes provides ample financial flexibility to execute our 2013 capital program and distribution strategy.

On February 14, 2013, LRR Energy paid its cash distribution for the fourth quarter of 2012 to all unitholders of record as of the close of business on January 30, 2013.  The Board of Directors of its general partner previously declared a cash distribution for the fourth quarter of 2012 of $0.4800 per outstanding unit, or $1.92 on an annualized basis.

Our average net production for February 2013 was approximately 5,900 Boe/d.  We expect our first quarter 2013 production to be negatively impacted by approximately 109 Boe/d relating to the Pecos Slope compressor failure discussed above.

2013 Guidance

Based on current estimates, and assuming no future acquisitions, our 2013 guidance is as follows:

Our annual maintenance capital expenditures were estimated based on 25% of pro forma trailing 12-month adjusted EBITDA. The guidance above sets forth management’s best estimate based on current and anticipated market conditions and other factors.  While we believe that these estimates and assumptions are reasonable, they are inherently uncertain and are subject to, among other things, significant business, economic, regulatory, environmental and competitive risks and uncertainties that could cause actual results to differ materially from those we anticipate, as set forth under “Forward-Looking Statements.”

Commodity Derivative Contracts

As of December 31, 2012, LRR Energy had the following outstanding derivative contracts.

Subsequent to December 31, 2012, LRR Energy entered into the following commodity hedges.

As part of the 2013 acquisition described above, LRE acquired the following crude oil and natural gas hedges:

We define Adjusted EBITDA as net income (loss) plus income tax expense (benefit); interest expense-net, including realized and unrealized losses on interest rate derivative contracts; depletion and depreciation; accretion of asset retirement obligations; amortization of equity awards; (gain) loss on settlement of asset retirement obligations; unrealized losses on commodity derivative contracts; impairment of oil and natural gas properties; less interest income; unrealized gains on commodity derivative contracts and other non-recurring items that we deem appropriate. Distributable Cash Flow is defined as Adjusted EBITDA less income tax expense; cash interest expense; and estimated maintenance capital expenditures. Distribution Coverage Ratio is defined as the ratio of Distributable Cash Flow to the total quarterly distribution payable on all of our outstanding common, subordinated and general partner units.

Adjusted EBITDA, Distributable Cash Flow and the Distribution Coverage Ratio are used as supplemental financial measures by our management and by external users of our financial statements, such as investors, commercial banks and others, to assess our operating performance as compared to that of other companies and partnerships in our industry, without regard to financing methods, capital structure or historical cost basis and the ability of our assets to generate sufficient cash flow to make distributions to our unitholders.

Our management believes that Adjusted EBITDA, Distributable Cash Flow and the Distribution Coverage Ratio are useful to investors because these measures are used by many partnerships in the industry as measures of operating and financial performance and are commonly employed by financial analysts and others to evaluate our operating and financial performance from period to period and to compare it with the performance of other publicly traded partnerships within the industry. Adjusted EBITDA, Distributable Cash Flow and the Distribution Coverage Ratio should not be considered alternatives to net income, operating income, cash flow from operating activities or any other measures of financial performance presented in accordance with GAAP. Our Adjusted EBITDA, Distributable Cash Flow and Distribution Coverage Ratio may not be comparable to similarly titled measures of another company because all companies may not calculate Adjusted EBITDA, Distributable Cash Flow or the Distribution Coverage Ratio in the same manner. The following table presents a reconciliation of Adjusted EBITDA to net income, our most directly comparable GAAP financial performance measure, for the three months and year ended December 31, 2012.

The following table presents a reconciliation of Distributable Cash Flow and the Distribution Coverage Ratio to Adjusted EBITDA for the three months and year ended December 31, 2012. Adjusted EBITDA is reconciled to net income, our most directly comparable GAAP financial performance measure, above.
