Memorial Resource Development Corp. Announces Second Quarter 2014 Results

HOUSTON, August 6, 2014 – Memorial Resource Development Corp. (Nasdaq: MRD) announced today its operating and financial results for the three months ended June 30, 2014.

Operational and financial highlights from the second quarter 2014 include:

“In our first quarter as a publicly-traded company, MRD delivered solid financial and operational results. Through our continued operational success in the Terryville Field, we increased quarterly production 32 percent compared to the first quarter 2014,” said John Weinzierl, Chief Executive Officer of MRD. “We’re off to a great start and look forward to executing on our goal of maximizing shareholder value through the horizontal development of this world-class asset.”

Mr. Weinzierl added, “We expect to continue running six horizontal rigs in total for MRD for the remainder of the year and anticipate picking up our seventh horizontal rig beginning in 2015. This is an exciting time for us as we look to accelerate development of our drilling inventory in the Terryville Field of North Louisiana.”

Second Quarter 2014 Results

Unless otherwise indicated, the operating and financial results discussed in this press release only include the MRD Segment, which includes all of our operations except for Memorial Production Partners LP and its subsidiaries (“MEMP”).⁽²⁾

MRD increased production 86% year-over-year to 222 MMcfe/d for the second quarter 2014 compared to 119 MMcfe/d for the second quarter 2013. Second quarter 2014 production consisted of 172 MMcf/d of natural gas, 5.6 MBbls/d of natural gas liquids (“NGLs”) and 2.7 MBbls/d of oil.

Total revenues increased approximately $56.4 million to $113.3 million for the second quarter 2014 from $56.9 million for the second quarter 2013. The increase was primarily due to production increases from MRD’s drilling activity in the Terryville Field.

Average realized prices for the second quarter 2014, before the effect of commodity derivatives, were $4.11 per Mcf of natural gas, $47.79 per Bbl of NGLs and $98.00 per Bbl of oil compared to $3.57 per Mcf of natural gas, $35.44 per Bbl of NGLs and $102.71 per Bbl of oil for the second quarter 2013. MRD’s realized pricing varies from NYMEX due to revenue deductions for the net costs of gathering, transporting and processing and regional basis differentials.

Lease operating expense (“LOE”) for the second quarter 2014 was $6.0 million, or $0.29 per Mcfe, compared to $5.8 million, or $0.54 per Mcfe, for the second quarter 2013. The decrease in per unit LOE resulted from increased sales volumes, the lower per unit operating cost attributable to horizontal wells and MRD’s continuous efforts to reduce costs.

Production and ad valorem taxes totaled $3.9 million for the second quarter 2014, or $0.19 per Mcfe, compared to $3.8 million, or $0.35 per Mcfe, for the second quarter 2013. Per unit production and ad valorem taxes decreased in the quarter compared to the prior year period primarily due to the utilization of temporary production tax rate incentives available on new wells drilled.

General and administrative (“G&A”) expense for the second quarter 2014 was $11.5 million, or $0.57 per Mcfe, compared to $9.5 million, or $0.88 per Mcfe, for the second quarter 2013.

Net interest expense during the second quarter 2014 was $16.5 million, including amortization of deferred financing fees of approximately $0.8 million. This compares to net interest expense during the second quarter 2013 of $4.1 million, including amortization of deferred financing fees of approximately $0.6 million. The year-over-year increase in net interest expense is primarily the result of higher level of indebtedness during 2014 compared to 2013, including the Senior PIK Toggle Notes and the $325.0 million second lien term facility at WildHorse Resources, LLC.

Adjusted Net Income⁽¹⁾ for the second quarter 2014 increased by $29.4 million to $44.8 million as compared to $15.4 million for the second quarter 2013.

Operational Update

MRD reported second quarter 2014 average production of 222 MMcfe/d, which represents a 32% sequential increase compared to the first quarter 2014. The increase was primarily driven by MRD’s drilling activity in the horizontal development of the Terryville Field. During the quarter, MRD brought online eight gross horizontal wells targeting the Upper and Lower Red zones. As of August 5, 2014, MRD had a total of 32 horizontal wells producing from the Terryville Field.

The following table provides certain operational data related to MRD’s horizontal wells added in the Terryville Field during the second quarter 2014:

In addition to the second quarter operational data noted above, MRD provided the following recent developments in the Terryville Field:

In early June, MRD completed a four-well pad targeting the Upper Red (2 wells) and Lower Red (2 wells) zones. These wells were drilled with an average 6,354 foot lateral and achieved a thirty-day initial production (“IP”) rate of approximately 75.2 MMcfe/d. Initial type curves indicate the pad is performing in line with management’s expectations. These wells were spaced approximately 725 feet across the same zone and stacked vertically between the Upper Red and Lower Red zones.

In late July, MRD completed a horizontal well targeting the Green interval, which is shallower and contains a higher liquids content than the overpressured Lower Cotton Valley zones. This well is located outside of Netherland, Sewell & Associates, Inc.’s (“NSAI”) proved, probable and possible (“3P”) area. The well began unloading last week.

During 2014, a majority of MRD’s planned horizontal wells are expected to be located outside of NSAI’s proved (“1P”) area. In addition, MRD expects to complete two additional Lower Cotton Valley wells outside of NSAI’s 3P area. Both wells are expected to target the Upper Red zone, and management expects these wells to begin production during the third and fourth quarters of 2014, respectively.

MRD continues to focus on maximizing shareholder value by growing production through the horizontal development of the Terryville Field. As planned, MRD added a fifth rig in the Terryville Field in June 2014. In addition to this rig, MRD added a sixth operated rig to the Terryville Field in late July 2014. This rig, which was originally scheduled to be deployed in MRD’s East Texas region, will be drilling a two well pad in the Terryville Field with first production expected in late December. MRD currently operates six rigs in total, all of which are located in the Terryville Field.

MRD expects to have access to an additional 200 MMcfe/d of processing capacity in the second quarter 2015, bringing the total available processing capacity to approximately 605 MMcfe/d. In addition to already contracted capacity, MRD continues to evaluate further potential processing capacity through a number of providers in the region.

In East Texas, MRD completed one well during the second quarter 2014 and recently completed another well during July 2014. Year-to-date, MRD has brought online a total of four wells in East Texas, all which have performed above management’s expectations. For the remainder of the year, MRD is scheduled to drill one additional well in East Texas and expects production from this well in early 2015. MRD anticipates completing one well in the Rockies during the second half of 2014.

Operational and Financial Guidance

MRD expects its fiscal year 2014 capital budget to total approximately $351 million, consisting of the following:

Assuming the execution of the capital plan described above, MRD anticipates that 2014 average daily production will be between 217 MMcfe/d and 245 MMcfe/d, consisting of approximately 77% natural gas (using the mid-point of MRD’s guidance range). Furthermore, in 2014 MRD expects to spud 43 gross wells and complete 33 gross wells in the Terryville Field. For the full year 2014, a summary of the guidance is presented below.

Note: Guidance as of August 6, 2014.

The guidance included in this press release is subject to the cautionary statements and limitations described under the “Cautionary Statement Concerning Forward-Looking Statements” caption of this press release. MRD’s guidance is based on, among other things, its current expectations regarding capital expenditure levels and the assumption that market demand and prices for oil, natural gas and NGLs will continue at a level that allow for economic production of these products.

Hedging Update

MRD utilizes its hedging program to mitigate financial risks and continues to add hedge positions as new volumes are brought online. In June 2014, MRD entered into additional natural gas, NGL and crude oil derivative contracts through December 2017. These incremental commodity hedges represent total natural gas volumes of 48.6 Bcfe for the period July 2014 – December 2017 at a weighted average price of $4.44 per MMBtu; total oil volumes of 0.7 MMBbls for the period July 2014 – December 2016 at a weighted average price of $94.05 per Bbl; and 1.6 MMBbls of NGLs for the period July 2014 – December 2015 at an average price of $41.66 per Bbl. Please see the “Commodity Hedge Positions” table at the end of this press release for more detailed information about MRD’s hedging program as of June 30, 2014.

Financial Update

On June 18, 2014, MRD completed its initial public offering (“IPO”) of 49.2 million shares of its common stock at $19.00 per share. MRD sold 21.5 million shares of its common stock and a selling stockholder sold 27.7 million shares of common stock. Net proceeds received by MRD from the IPO were approximately $380.7 million after deducting underwriting discounts and commissions and estimated offering expenses.

On June 25, 2014, MRD priced $600 million in aggregate principal amount of 5.875% senior unsecured notes due 2022 at par. MRD used the net proceeds of approximately $586 million to repay a portion of the borrowings outstanding under its revolving credit facility. Following the upsized senior notes offering, MRD’s borrowing base on its revolving credit facility was reduced by $56.5 million to $668.5 million.

As of June 30, 2014, MRD’s liquidity of $121.6 million consisted of $15.6 million of cash and cash equivalents and $106.0 million of available borrowings under its revolving credit facility. As of June 30, 2014, after giving effect to the senior notes offering and the application of the net proceeds therefrom, MRD would have had approximately $635.5 million of available borrowing capacity under its revolving credit facility and approximately $15.6 million of cash and cash equivalents, providing total liquidity of approximately $651.1 million.

Such forward-looking statements are subject to a number of risks and uncertainties, many of which are beyond MRD’s control. All statements, other than historical facts included in this press release, that address activities, events or developments that MRD expects or anticipates will or may occur in the future, including such things as MRD’s future capital expenditures (including the amount and nature thereof), business strategy and measures to implement strategy, competitive strengths, goals, expansion and growth of MRD’s business and operations, plans, market conditions, references to future success, references to intentions as to future matters and other such matters are forward-looking statements. All forward-looking statements speak only as of the date of this press release. Although MRD believes that the plans, intentions and expectations reflected in or suggested by the forward-looking statements are reasonable, there is no assurance that these plans, intentions or expectations will be achieved. Therefore, actual outcomes and results could materially differ from what is expressed, implied or forecast in such statements.

MRD cautions you that these forward-looking statements are subject to risks and uncertainties, most of which are difficult to predict and many of which are beyond MRD’s control, incident to the exploration for and development, production, gathering and sale of natural gas and oil. These risks include, but are not limited to: commodity price volatility; inflation; lack of availability of drilling and production equipment and services; environmental risks; drilling and other operating risks; regulatory changes; the uncertainty inherent in estimating natural gas and oil reserves and in projecting future rates of production, cash flow and access to capital; and the timing of development expenditures.

Use of Non-GAAP Financial Measures

This press release and accompanying schedules include the non-GAAP financial measures of Adjusted EBITDA and Adjusted Net Income. 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. MRD’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. MRD’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 MRD does.

Memorial Resource Development Corp.

Calculation of Adjusted Net Income - MRD Segment

MRD Segment Adjusted Net Income is a supplemental non-GAAP financial measure that is used by external users of MRD’s financial statements. We define MRD Segment Adjusted Net Income as net income excluding the impact of certain items including gains or losses on commodity derivative instruments not yet settled, gains or losses on sales of properties, debt extinguishment costs, equity income in MEMP, impairment of oil and gas properties, and incentive-based compensation expense. We believe MRD Segment Adjusted Net Income is useful to investors because it provides readers with a more meaningful measure of our profitability before recording certain items for which the timing or amount cannot be reasonably determined. However, this measure is provided in addition to, not as an alternative for, and should be read in conjunction with, the information contained in our financial statements prepared in accordance with GAAP. The following table provides a reconciliation of net income (loss) as determined in accordance with GAAP to adjusted net income for the periods indicated:
