Rex Energy Reports Continued Growth with Strong Third-Quarter 2007 Results
STATE COLLEGE, Pa.--(BUSINESS WIRE)--Nov. 14, 2007--Rex Energy Corporation (NASDAQ:REXX) today announced results for the third quarter of 2007. Highlights for the third quarter 2007 include:

  • Production volumes were 258,027 of oil equivalent "BOE", up 38% from the same period in 2006 and up 7% from the second quarter of 2007;
  • Revenues grew 50% over the same period in 2006 and 13% over the second quarter of 2007;
  • Production and lease operating expenses decreased 7% from the second quarter of 2007; and
  • EBITDAX grew 56% over the same period 2006 and grew 39% over the second quarter of 2007.

Commenting on the announcement, Benjamin Hulburt, Rex Energy Corporation's CEO, said, "The third quarter results reflect continued growth in our production and cash flow as a result of our operating team's successful implementation of our business plan. The foundation for these results is our extensive exploration and developmental drilling inventory that includes more than 2,500 locations. We continue to believe we are extremely well positioned, as our developmental drilling programs continue to grow our production base in each of our operating regions, while our larger upside projects such as the Alkali Surfactant Polymer flood in the Lawrence field continues to progress. We've maintained a conservative balance sheet with approximately 6% debt to market capitalization and believe we have the right team, and the right capital structure to meet our growth objectives."

Production in the third quarter of 2007 totaled 258,027 BOE, of which approximately 81% was attributable to oil. Production volumes increased 38% from the same period in 2006, and 7% over the second quarter of 2007. Approximately 75% of the third quarter 2007 production was from the company's Illinois Basin operations, 12% was from its Appalachian Basin operations, and 13% was from its Southwestern region operations.

Revenues for the third quarter of 2007 were $15.1 million, representing a 50% increase over revenues of $10.1 million in the third quarter of 2006, and an increase of approximately $1.7 million, or 13%, over the second quarter of 2007, net of unrealized loss on derivatives.

The company's average realized oil price, before the effect of derivatives, was $70.78 per barrel ("Bbl") in the third quarter of 2007, up 6.8% from $66.26 per Bbl in the third quarter of 2006. The company's average realized natural gas price, before the effects of derivatives, was $6.21 per thousand cubic feet ("Mcf") of natural gas in the third quarter of 2007, down from $6.39 per Mcf of natural gas in the third quarter of 2006.

Total operating expenses for the third quarter 2007 were $13.7 million, up from $8.0 million in the third quarter of 2006. Production and Lease operating expenses were $5.9 million in the third quarter of 2007, up from $4.2 million in the same period in 2006, but down from $6.3 million in the second quarter of 2007. General and administrative expenses were $1.8 million in the third quarter of 2007, up from $1.0 million in the third quarter of 2006.

The company did not incur any exploration expenses in the third quarter of 2007. Depreciation, depletion, amortization, and accretion ("DD&A") expenses were $5.8 million in the third quarter of 2007, up from $2.6 million in the third quarter of 2006. The increase in DD&A expenses was primarily caused by acquisitions completed during 2006, and an increase in the company's assets associated with its initial public offering, reorganization and acquisition of minority interests.

The company reported a loss before minority interests and provision for taxes of $1.7 million in the third quarter of 2007 compared with net income before minority interest of $6.7 million in the third quarter of 2006. All of the minority interests were acquired as part of the company's initial public offering and reorganization which closed on July 30, 2007. Net income comparable to analyst estimates, a non-GAAP measure, was $670,000 or $0.02 per fully diluted share, up from $571,000 in the third quarter of 2006. (See the accompanying table reconciling this non-GAAP measure.)

EBITDAX, a non-GAAP measure, was $7.5 million in the third quarter of 2007. This represented an increase of 56% over the third quarter of 2006, and an increase of 39% over the second quarter of 2007 (See the accompanying table reconciling this non-GAAP measure.). Cash flows from operations for the nine months ended September 30, 2007 grew 10% from the same period in 2006 to $11.5 million.

Capital expenditures for drilling & development in the third quarter 2007 were $7.8 million, which funded the drilling or recompletion of 34 gross wells (25 net wells) and related improvements to infrastructure. Of the wells drilled or recompleted, 17 gross wells (14 net wells) are producing, 13 gross wells (10 net wells) are expected to be productive but are awaiting completion, and 4 gross wells (1 net well) are continuing to be evaluated to determine if they will be economical to produce. Additionally, $1.2 million was spent on acquisitions, equipment and leasing during the third quarter of 2007.

In the Appalachian Basin, the company intends to drill approximately 37 gross (24 net) conventional natural gas wells by the end of 2007, of which 24 gross (12 net) wells were drilled by the end of third quarter 2007. Additionally, the company is continuing to add acreage in areas where it believes the Marcellus Shale may be prospective and intends to test certain areas of its acreage in Pennsylvania for the Marcellus Shale during the fourth quarter of 2007 or first quarter of 2008.

In the Permian Basin, the company intends to drill or recomplete approximately 26 gross (23 net) wells by the end of 2007, of which 12 gross (10 net) wells had been drilled by the end of third quarter 2007. One of these wells was determined to be dry and was expensed in both the first and second quarters.

In the Illinois Basin, the company intends to drill or recomplete approximately 70 gross (69 net) conventional oil wells by the end of 2007, of which 42 gross (41 net) wells had been drilled by the end of third quarter 2007. Additionally, the company is continuing to evaluate its New Albany Shale acreage by analyzing and refining its drilling, completion and stimulation procedures. The company expects to drill an additional 1-2 horizontal wells in this project by year- end.

The company is continuing to move forward with its Alkali Surfactant Polymer tertiary recovery project in the Lawrence Field in the Illinois Basin. The company has drilled all eighteen pilot wells, completed the upgrade of the pilot area production facilities, installed the production flow-lines to both pilot areas and began the installation of the pilot injection pipelines. Additionally, the company's technical consultants have completed their linear and radial core flood analysis on the Cypress sandstone, which in the laboratory has resulted in an oil recovery rate as high as 21% of the estimated original oil-in-place. These results are in line with the company's initial projections. The analysis on the Bridgeport sandstone is continuing and is expected to be complete in the fourth quarter 2007. The company expects to break ground on the construction of its first ASP injection plant during the fourth quarter 2007. Due to delays in the expected delivery of certain equipment needed to begin chemical injection, the company now expects to begin injecting the ASP chemicals in the pilot areas during the second quarter of 2008.

Commenting on the company's ASP project, Mr. Hulburt said "We are very pleased that the testing of the Cypress sandstone has resulted in an oil recovery rate which is in line with our initial projections. While we are disappointed in the short delay regarding the completion of the injection plant, we do not, at this time, believe these delays will prevent us from accomplishing our goal of obtaining sufficient information from our pilot tests to assist us in estimating proven reserves from the ASP process in the Lawrence Field by year end 2008."

The company is reaffirming its previous guidance for the fourth quarter of 2007 and provides the following update to its forecasts for capital expenditures, production and production exit rates, based upon the information available at the time of this release. Please see the forward-looking statements cautionary statement at the end of this release for more discussion of the inherent limitations of this information.

    Non-GAAP Financial Measures


EBITDAX

"EBITDAX" 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: interest, income taxes, depreciation, depletion, amortization, 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 the company's management team and by other users of its financial statements, such as the company's commercial bank lenders, to analyze such things as:

  • The company'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;
  • The company'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 of 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.

The company 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 the company 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 be fully available for management's discretionary use, due to requirements to conserve funds for capital expenditures, debt service and other commitments.

The company 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 its ability to generate cash available for distribution. Because the company 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, the company believes it is important to consider both net income determined under GAAP and EBITDAX to evaluate its performance.

The following table presents a reconciliation of the company's net income to its EBITDAX 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: minority interest share of net income which were acquired as part of the company's reorganization on July 30, 2007, deferred income taxes, unrealized gains or losses from financial derivatives, minus gains from unrealized financial derivatives, minus deferred income tax benefits, added to net income. Earnings Comparable with Analyst Estimates, as defined above, is used as a financial measure by the company's management team and by other users of its financial statements, to analyze its financial performance without regard to minority interests which were all acquired as part of the company's reorganization on July 30, 2007, non-cash deferred taxes and non-cash unrealized losses or gains from oil and gas derivatives. Earnings Comparable with Analysts 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.

The company has reported Earning Comparable with Analyst Estimates because its 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 computations of this measure. You are cautioned that Earnings Comparable with Analyst Estimates as reported by the company may not be comparable in all instances to that reported by other companies.

To compensate for these limitations, the company believes it is important to consider both net income determined under GAAP and Earnings Comparable with Analyst Estimates.
