STATE COLLEGE, Pa., Feb. 21, 2012 (GLOBE NEWSWIRE) -- Rex Energy Corporation (Rex Energy or the company) (Nasdaq:REXX) today announced its fourth quarter 2011 and full-year 2011 operational and financial results and provided its updated 2012 capital budget and revised guidance.

Fourth Quarter Operational and Financial Results

Operating revenue from continuing operations was $31.7 million for the fourth quarter 2011, which is an increase of 63% over the same period of 2010. Commodity revenues, including cash settled derivatives, were $33.2 million, of which 57% was attributable to oil and natural gas liquids and 43% was attributable to natural gas. Realized prices for oil, including cash-settled derivatives, were $90.32 per barrel. Realized prices for natural gas, including cash-settled derivatives, were $4.57 per Mcf and realized prices for NGLs were $54.10 per barrel, which was 58% of the average quoted NYMEX price for the fourth quarter.

Production and lease operating expenses from continuing operations for the fourth quarter 2011 were $9.1 million, which is an increase of 40% over the fourth quarter 2010. The increase in production and lease operating expense is primarily the result of growth in the number of producing wells in the Appalachia Basin. Cash general and administrative expenses from continuing operations were $4.7 million, a 12% increase over the fourth quarter of 2010.

Net income from continuing operations for the fourth quarter 2011 was $1.1 million, or $0.03 per share. Loss from discontinued operations for the fourth quarter 2011 was $4.3 million, or $0.10 per share. EBITDAX from continuing operations, a non-GAAP measure, was $19.8 million for the fourth quarter. This was an increase of 3% over the third quarter of 2011 and an increase of 139% over the fourth quarter 2010. A reconciliation between EBITDAX and GAAP net income is presented in the financial highlights attached to this release.

The company incurred impairment expenses of $11.7 million from continuing operations in the fourth quarter 2011 related to the write-down of the company's legacy conventional shallow-well natural gas properties in the Appalachia Basin.

Full-Year 2011 Financial and Operational Results

Operating revenues from continuing operations for the full-year 2011 were $114.6 million, which is an increase of 67% over full year 2010 operating revenues. Commodity revenues, including cash-settled derivatives, were $118.1 million for the full year 2011, of which 62% was attributable to oil and natural gas liquids and 38% was attributable to natural gas. Realized prices for oil, including cash-settled derivatives were $90.50 per barrel. Realized prices for natural gas, including cash-settled derivatives were $5.05 per Mcf and realized prices for NGLs were $53.66 per barrel, which was 56% of the average quoted NYMEX oil price for 2011.

For the full-year 2011, production and lease operating expenses from continuing operations were $33.1 million, which is an increase of 34% over full year 2010. The increase is attributable to the company's growing number of producing wells in the Appalachia Basin. Cash general and administrative expenses from continued operations were $22.0 million, increasing from $16.2 million in 2010.

Net income from continuing operations for the full-year 2011 was $18.1 million, or $0.41 per share. Loss from discontinued operations for the full-year 2011 was $33.5 million, or $0.76 per share. EBITDAX from continuing operations, a non-GAAP measure, was $64.5 million for the full year 2011, representing an increase of 139% over the full-year 2010.

2011 Capital Expenditures

Capital expenditures for the full-year 2011 totaled $302.4 million with $24.0 million attributable to discontinued operations in the company's Niobrara shale area. This is above the company's previously issued guidance of $270.0 million. The increase above previous guidance was due to the acceleration of leasing activity in the Warrior Prospect, additional costs related to drilling and completion in the Appalachia Basin and capital expenditures related to the Niobrara shale area.

The following table shows a breakdown of the company's 2011 capital expenditures ($ in millions): 

Revised 2012 Capital Expenditure Budget

Given the recent weakness in natural gas prices, the company is reducing and reallocating its capital expenditure budget for 2012 into its more liquids-rich areas. With the changes outlined below, the company will now have 85% of its total capital budget allocated to its oil and liquids-rich project areas.

In the Butler County operated areas of Pennsylvania, the capital program targeting the dry gas portion of the Utica Shale has been reduced from drilling three gross (2.1 net) wells and completing one gross (0.7 net) well to drilling one gross (0.7 net) Utica Shale well. The capital from the remaining two gross (1.4 net) Utica shale wells will be used to drill two gross (1.4 net) Marcellus Shale wells, which are in the liquids-rich zone. In addition, the company plans to drill and complete one gross (0.7 net) Upper Devonian/Rhinestreet Shale well. The Rhinestreet Shale lies approximately 400 feet above the Burkett Shale and is 130 feet thick in the Butler County area. Based on log analysis, the Rhinestreet Shale appears to be similar to the Marcellus and Burkett Shales in terms of organic carbon content and porosity. Since the Rhinestreet Shale is approximately 400 and 600 feet shallower than the Burkett and Marcellus Shales, respectively, the company anticipates it will produce at a higher liquids content than either of the deeper plays.

In the company's non-operated areas of Westmoreland, Clearfield and Centre Counties, Pennsylvania, where WPX Energy serves as the operator, the company has reduced the number of wells expected to be drilled from the previously announced 17 gross (6.8 net) wells to 7 gross (2.8 net) wells. Rex Energy has also reduced the number of wells expected to be fracture stimulated in 2012 from the previously announced 16 gross (6.4 net) wells to 1 gross (0.4 net) wells. The number of wells expected to be placed into service during 2012 has also been reduced from the previously announced 16 gross (6.4 net) to zero. The company expects to have 10 gross (4.0 net) wells drilled and awaiting completion in the non-operated area at the end of 2012. Midstream capital in these areas was reduced from $9.0 million to $5.0 million. Total capital in the Westmoreland, Clearfield and Centre County non-operated areas has been reduced from $56.4 million to $22.0 million or 61%.

More information on the 2012 revised capital budget is available in the company's current corporate presentation, which can be viewed through the company's website www.rexenergy.com.

The company has provided a revised operational capital budget in the table below ($ in millions): 

First Quarter and Revised Full Year 2012 Guidance

Rex Energy has provided its revised guidance for the first quarter of 2012 and full year 2012: 

Operational Update

Appalachia Basin - Butler County, Pennsylvania Operated Area

In the Butler operated area, the company's midstream partner, Keystone Midstream Services, has commissioned the Voll Compressor Station which will increase the inlet capacity of the Sarsen plant by 6 MMcf/d. This increase of inlet capacity is expected to bring the Sarsen plant to its fully rated capacity of 40 MMcf/d.

Keystone Midstream also remains on schedule to commission the Bluestone cryogenic processing plant in May of this year. Bluestone will have a full inlet capacity of 50 MMcf/d and will not require additional field compression.

Rex Energy has completed pipeline construction to its first Utica Shale test well in Butler County, the Cheeseman #1H. The well is expected to have first sales by March 1^st. Updated well information will be provided on the company's first quarter call.

The company has recently fracture stimulated and placed into service the remaining four wells on the seven well Grosick pad.  The company expects to provide an update on the Grosick pad during its first quarter conference call. The company has also completed drilling activities on the two well Plesniak pad, and the wells are currently awaiting completion.

Appalachia Basin - Warrior Prospect, Carroll County, Ohio

In the Warrior Prospect, Rex Energy is expecting to spud its first Utica Shale well in April and anticipates completion results to be available during the second quarter conference call in August. The locations of the first two wells have been disclosed in the company's current corporate presentation under its Warrior Prospect section.

To date the company has closed on approximately 13,700 net acres of the previously announced 15,000 net acres. The remaining acreage is expected to close during the first quarter of the year.

Appalachia Basin - Westmoreland, Clearfield, and Centre Counties Non-Operated Area

In the company's non-operated area in Westmoreland County, Pennsylvania, where WPX Energy serves as the operator, WPX has completed drilling operations on the three well Corbett pad. The drilling rig is currently moving onto the Gera pad, where it will drill one well. There are currently no additional completion operations planned.

In the Westmoreland County non-operated area, the seven previously announced wells on the Marco #1 pad and the National Metals #1 pad had combined average 60 day sales rates of 4.1 MMcf/d per well. These results are approximately 41% above the company's current 30 day rate (3.1 MMcf/d) and 56% above the company's current 60 day rate (2.6 MMcf/d) given for a 4.2 Bcf well type curve for this area. WPX continues to increase sales rates in the Westmoreland County area, with average gross sales rates of approximately 65.2 MMcf/d in the Westmoreland field during the month of January.

Illinois Basin - ASP Project Update

In Rex Energy's ASP project areas in the Illinois Basin, the company continues to move forward with its expansion into the 58 acre Perkins-Smith area. The company expects to begin ASP flooding of the Perkins-Smith project in the second quarter. In the 351 acre high impact Delta Unit, the company is in the process of completing technical work in preparation for its planned tracer injection surveying in the third quarter and ASP injection in the second quarter of 2013.

Midstream and Niobrara Asset Divestiture

The company is progressing with its divestiture plans for its Rockies assets and Butler midstream assets. The company expects these sales to close during the first half of 2012 and provide the company with an estimated $90-$110 million of liquidity.

The following table has been added to provide clarification on the components of Gain on Derivatives, net under Other Income (Expense) on the Consolidated Statements of Operations for each of the periods presented (in thousands):

Non-GAAP Financial Measures

EBITDAX

"EBITDAX" means, for any defined period, the sum of net income for the period plus the following expenses, charges or income, in each case, to the extent deducted from or added to net income in the 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 (without limitation) income from unrealized financial derivatives, added to net income. EBITDAX 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.

Rex Energy believes it is important to consider both net income (loss) determined under GAAP and EBITDAX to evaluate its performance.

Earnings Comparable with Analyst Estimates

"Earnings Comparable with Analyst Estimates" means, for any period, the sum of net income for the period plus the following expenses, charges or income, in each case, to the extent deducted from or added to net income in the period: unrealized losses from financial derivatives, non-cash compensation expense, dry hole expenses and impairment, minus all gains from unrealized financial derivatives and deferred income tax benefits, added to net income. Earnings Comparable with Analyst Estimates 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.

Rex Energy has reported Earnings Comparable with Analyst Estimates because it believes that this measure is commonly reported and widely used by investors as an indicator of a company's operating performance. You should carefully consider the specific items included in the company's computation of this measure. You are cautioned that Earnings Comparable with Analyst Estimates as reported by Rex Energy may not be comparable in all instances to that reported by other companies.

Rex Energy believes it is important to consider both net income determined under GAAP and Earnings Comparable with Analyst Estimates.
