Rex Energy Corporation Announces Third Quarter 2010 Results

STATE COLLEGE, Pa., Nov 1, 2010 (GlobeNewswire via COMTEX News Network) -- Rex Energy Corporation ("Rex Energy") (Nasdaq:REXX) today announced financial and operational results for the third quarter of 2010. Highlights include:

  --  Keystone Midstream Services' Sarsen Plant, the company's jointly owned
      cryogenic gas processing plant in Butler County, Pennsylvania, is
      commissioning operating systems in the facility, and is expected to be
      capable of processing 20 MMcf per day by mid-November 2010;

  --  The company's most recent Marcellus Shale horizontal well in
      Westmoreland County, Pennsylvania tested at an initial production rate
      of 3.5 MMcf per day over a 24 hour period;

  --  Production for both the first nine months and third quarter was up 23%
      and 26%, respectively, over the same periods in 2009;

  --  Operating revenue for both the first nine months and third quarter was
      up 47% and 29%, respectively, over the same periods in 2009, and;

  --  EBITDAX for both the first nine months and third quarter was up 35% and
      10%, respectively, over the same periods in 2009.


Production during the third quarter averaged 20.3 MMcfe per day, which was within the company's guidance for the period and was comprised of 56% oil, 41% natural gas and 3% natural gas liquids. Realized gas prices after adjustment for cash settled derivatives during the period were $5.85 per Mcf, as compared to $6.33 per Mcf in the prior year quarter. Realized oil prices after adjustment for cash settled derivatives during the period were $69.02 per Bbl, as compared to $63.05 per Bbl in the prior year quarter. As a result, oil and gas sales, including cash settled derivatives, increased 22% over the third quarter 2009 to approximately $16.8 million. EBITDAX from continuing operations, a non-GAAP financial measure, increased to $5.7 million, which represents a 10% increase over the same period in 2009. The company recorded net income for the quarter of $9.6 million, or $0.22 per share. Adjusting for certain non-cash items, earnings comparable to analyst estimates was $0.4 million, or $0.01 per share.

Lance T. Shaner, Rex Energy's Interim President and CEO, commented, "I am extremely pleased to announce the start-up of the Sarsen Plant in Butler County. While the cryogenic plant is currently commissioning and will not be fully operational until later this month, the company will now be able to continue to increase its liquids rich Marcellus Shale gas production in this region."

Operational Updates

Butler County, Pennsylvania Marcellus Project Area

In the company's liquids rich Marcellus Shale project area, Keystone Midstream Services' Sarsen Plant is commissioning operating systems in the plant in preparation for startup. Rex Energy expects to be processing approximately 10.0 MMcf per day by mid-November 2010 at which time the Sarsen Plant will have initial compression in place to process up to 20.0 MMcf per day. Additional inlet compression to increase plant throughput capacity to 30.0 MMcf per day is scheduled to be installed in mid-January 2011, and compression for the full plant capacity of 40.0 MMcf per day is scheduled to be added by the end of the first quarter 2011.

In early October 2010, Rex Energy fracture stimulated the Shannon #1H with 10 stages over the 2,870 feet of lateral extension. The company was extremely encouraged by the treating pressure profile and fracture extent on micro-seismic data from the well. The Shannon #1H is currently being flow tested with approximately 5% of the water returned to surface. To date, the well has tested at an initial peak 24 hour rate of 2.2 gross MMcfe during clean up.

Concurrent with the fracture stimulation of the Shannon #1H, the company proceeded to fracture the Shannon #2H, but ceased operations during the second stage when a casing integrity issue was detected. A similar casing integrity issue was observed on the Voll #1H, and therefore the fracture stimulation of five wells awaiting completion has been delayed until later in 2010 to perform the required remedial well work.

Rex Energy owns a 70% working interest in all Butler County, Pennsylvania wells mentioned.

Williams Joint Venture Marcellus Project Areas

In Westmoreland County, Pennsylvania, Williams recently completed the Slavek Trust #3H, and the well's 24-hour peak rate of production was reported at 3.5 gross MMcf per day. Williams has moved the rig in this project area to the Uschak 2 pad and is currently drilling the fourth of five planned wells.

In Clearfield County, Pennsylvania, Williams has contracted a second joint venture rig and drilled the Alder Run #2H, which the company anticipates completing by year-end 2010. Williams is currently drilling the Alder Run #5H and will subsequently move this rig to Westmoreland County. As previously announced, the Alder Run #1H and #3H, which were drilled and completed in 2009, were put into production in September 2010 at a combined 24 hour peak rate of 6.9 gross MMcf per day.

Rex Energy owns a 40% working interest in all of the Williams Joint Venture Marcellus Project Area wells mentioned.

Illinois Basin

In the Illinois Region, Rex Energy's enhanced oil recovery team continues to inject chemicals in the Middagh Unit, the company's first field size alkali-surfactant-polymer ("ASP") flood unit designed to target the Bridgeport Sandstone. The company has reached injection of approximately 12% of the pore volume and expects an initial response in late first quarter 2011 to early second quarter 2011.

DJ Basin

In the Niobrara Shale play, Rex Energy completed a 13 stage slick water fracture stimulation of the Silo State 41-22 in late September 2010. This well is located in the southern part of the Silo Field, offsetting a previously completed 4,000 foot lateral unstimulated Niobrara well drilled in 1993 that produced just over 20,000 barrels of oil before abandonment. Although Rex Energy noticed indications of partial depletion of the reservoir during drilling, the fracture stimulation increased bottom-hole pressure, indicating that areas of virgin reservoir were contacted by the fracture stimulation.

During the initial flowback of the Silo-State 41-22, the tubing work string parted and had to be repaired which caused a ten day delay in the completion. Currently, the company has recovered approximately 20% of the fracture load with increasing oil cuts. The company will put this well on artificial lift and expects to get an initial production rate within the next few weeks.

Rex Energy has reached total depth on the Herrington Farms 1H, its second Niobrara Shale well, with an approximate 4,300 foot lateral extension and plans to begin completion operations in November 2010. The well is located approximately 12 miles east of the Silo State 41-22, and outside of any previously developed Niobrara production. As the company previously announced, it commenced oil sales from the Herrington Farms 1H during drilling operations. Rex Energy has four additional Niobrara Shale drilling permits and plans to spud the BJB #1H by year-end 2010.

Fourth Quarter and Year-End 2010 Guidance

Rex Energy's following forecasts and estimates are forward-looking statements subject to the risks and uncertainties identified in the "Forward-Looking Statements Disclosure" at the end of this release.

The company expects production volumes in the fourth quarter 2010 to continue to increase and anticipates production between 22.0 MMcfe per day and 25.0 MMcfe per day and expects that crude oil volumes will comprise approximately 51% of the average daily production. Therefore, Rex Energy is reaffirming its 2010 annual production guidance of 20.0 MMcfe and 23.0 MMcfe per day, but due to Marcellus completion delays, expects production to be toward the lower end of the guidance.

Based on the mid-point of the Rex Energy's production guidance, the company projects lease operating expenses in the fourth quarter to be approximately $7.8 million, and therefore is reaffirming its previous guidance of $26.0 million of expense for the full-year 2010. Rex Energy projects cash general and administrative ("G&A") expenses in the fourth quarter 2010 to be approximately $4.4 million which will increase the company's full-year cash G&A expenses to approximately $17.0 million. The increase is a result of higher than expected cash G&A expenses in the third quarter 2010 which was attributable to legal expenses associated with the Sumitomo joint venture.

(EBITDAX and Earnings/Net Loss Comparable to Analyst Estimates are non-GAAP financial measures. Please see the accompanying definitions and tables for the reconciliation of each of these non-GAAP measures. The company has classified all first quarter 2009 and prior period amounts related to its operations in the Southwestern Region as discontinued operations due to the sale of these assets during the first quarter of 2009. Please see the accompanying table for the reconciliation of the reported GAAP amounts to the amounts that would have been reported if Southwestern Region operations were included in continuing operations.)

Non-GAAP Financial Measures

EBITDAX

"EBITDAX" means, for any defined period, the sum of net income for such period plus the following expenses, charges or income to the extent deducted from or added to net income in such period: interest, income taxes, depreciation, depletion, amortization, accretion, unrealized losses from financial derivatives, exploration expenses, and other similar non-cash charges, minus all non-cash income, including but not limited to, income from unrealized financial derivatives, added to net income. EBITDAX, as defined above, is used as a financial measure by Rex Energy's management team and by other users of its financial statements, such as the company's commercial bank lenders, to analyze such things as:

  --  Rex Energy's operating performance and return on capital in comparison
      to those of other companies in its industry, without regard to financial
      or capital structure;
  --  The financial performance of the company's assets and valuation of the
      entity, without regard to financing methods, capital structure or
      historical cost basis;
  --  Rex Energy's ability to generate cash sufficient to pay interest costs,
      support its indebtedness and make cash distributions to its
      stockholders; and
  --  The viability of acquisitions and capital expenditure projects and the
      overall rates or return on alternative investment opportunities


EBITDAX is not a calculation based on GAAP financial measures and should not be considered as an alternative to net income (loss) in measuring the company's performance, nor used as an exclusive measure of cash flow, because it does not consider the impact of working capital growth, capital expenditures, debt principal reductions, and other sources and uses of cash, which are disclosed in the company's statements of cash flows.

Rex Energy has reported EBITDAX because it is a financial measure used by its existing commercial lenders, and because this measure is commonly reported and widely used by investors as an indicator of a company's operating performance and ability to incur and service debt. You should carefully consider the specific items included in the company's computations of EBITDAX. While Rex Energy has disclosed its EBITDAX to permit a more complete comparative analysis of its operating performance and debt servicing ability relative to other companies, you are cautioned that EBITDAX as reported by the company may not be comparable in all instances to EBITDAX as reported by other companies. EBITDAX amounts may not by fully available for management's discretionary use, due to requirements to conserve funds for capital expenditures, debt service and other commitments.

Rex Energy believes that EBITDAX assists its lenders and investors in comparing a company's performance on a consistent basis without regard to certain expenses, which can vary significantly depending upon accounting methods. Because the company may borrow money to finance its operations, interest expense is a necessary element of its costs and ability to generate cash available for distribution. Because Rex Energy uses capital assets, depreciation and amortization are also necessary elements of its costs. Additionally, the company is required to pay federal and state taxes, which are necessary elements of its costs. Therefore, any measures that exclude these elements have material limitations.

To compensate for these limitations, Rex Energy believes it is important to consider both net income (loss) determined under GAAP and EBITDAX to evaluate its performance.

The following table presents a reconciliation of the company's net (loss) from continuing operations to its EBITDAX from continuing operations for each of the periods presented ($ in thousands):

Earnings Comparable with Analyst Estimates

"Earnings Comparable with Analyst Estimates" means, for any period, the sum of net income for such period plus the following expenses, charges or income to the extent deducted from or added to net income in such period: deferred income taxes, unrealized losses from financial derivatives, non-cash compensation and impairment, minus all gains from unrealized financial derivatives and deferred income tax benefits, added to net income. Earnings Comparable with Analyst Estimates, as defined above, is used as a financial measure by Rex Energy's management team and by other users of its financial statements, to analyze its financial performance without regard to non-cash deferred taxes and non-cash unrealized losses or gains from oil and gas derivatives. Earnings Comparable with Analyst Estimates is not a calculation based on GAAP financial measures and should not be considered as an alternative to net income (loss) in measuring the company's performance.
