Our business
 
Business
 
We are engaged in the exploration, development and acquisition of oil and gas properties, primarily in the Southwestern, Appalachian and Gulf Coast regions of the United States. We seek to increase reserves and production through internally generated drilling projects coupled with complementary acquisitions.
 
At year-end 2006, our proved reserves had the following characteristics:
 
•  1.8 Tcfe of proved reserves;
 
•  82% natural gas;
 
•  63% proved developed;
 
•  80% operated;
 
•  a reserve life of 16.3 years (based on fourth quarter 2006 production); and
 
•  a pre-tax present value of $2.8 billion (2.0 billion after tax).
 
At year-end 2006, we owned 3,215,000 gross (2,500,000 net) acres of leasehold, which includes over 70,000 of acres associated with royalties. We have built a multi-year inventory of drilling projects which is estimated to be over 9,400 identified drilling locations.
 
Range was incorporated in early 1980 under the name Lomak Petroleum, Inc. and, later that year, we completed an initial public offering and began trading on the NASDAQ. In 1996, our common stock was listed on the New York Stock Exchange. In 1998, we changed our name to Range Resources Corporation. In 1999, we implemented a strategy of internally generated drillbit growth coupled with complementary acquisitions. Our objective is to build stockholder value through consistent growth in reserves and production on a cost-efficient basis. From January 1, 2002 to December 31, 2006, we have increased our proved reserves 243%, while production increased 81% during that same period.
 
Our corporate offices are located at 777 Main Street, Suite 800, Fort Worth, Texas 76102. Our telephone number is (817) 870-2601. Effective May 1, 2007, our corporate offices will be located at 100 Throckmorton Street, Suite 1200, Fort Worth, Texas 76102.

Business strategy
 
Our objective is to build stockholder value through consistent growth in reserves and production on a cost-efficient basis. Our strategy is to employ internally generated drillbit growth coupled with complementary acquisitions to achieve such growth. Our strategy requires us to make significant investments in technical staff, acreage and seismic to build drilling inventory. In implementing our strategy, we employ the following principal elements:
 
•  Concentrate in Core Operating Areas. We currently operate in three regions; the Southwestern (which includes the Barnett Shale of North Central Texas, Permian Basin of West Texas and eastern New Mexico, the East Texas Basin, the Texas Panhandle and Anadarko Basin of Western Oklahoma), Appalachian and Gulf Coast. Concentrating our drilling and producing activities in these core areas allows us to develop the regional expertise needed to interpret specific geological and operating trends and develop economies of scale. Operating in multiple core areas allows us to combine the production characteristics of each area to balance our portfolio toward our goal of consistent production and reserve growth.
 
•  Maintain Multi-Year Drilling Inventory. We focus on areas where multiple prospective productive horizons and development opportunities exist. We use our technical expertise to build and maintain a multi-year drilling inventory. We believe that maintaining a large, multi-year inventory of drilling projects enhances our ability to consistently grow production and reserves over the next several years. Currently, we have over 9,400 identified drilling locations in inventory. In 2006, we drilled 1,017 gross (704 net) wells. In 2007, our capital program targets the drilling of 924 gross (691 net) wells.
 
•  Make Complementary Acquisitions. We target complementary acquisitions in existing core areas and focus on acquisition candidates where our existing scientific knowledge is transferable and drilling results can be forecast with confidence. Over the past three years, we have completed $1.3 billion of complementary acquisitions located in our core operating areas.
 
•  Manage Our Risk Exposure. Allocating the majority of our capital spending to long-term development projects in areas where multiple productive horizons exist serves to reduce our risk exposure. Where our exploration projects may involve high dry hole costs, we often bring in industry partners in order to reduce financial exposure. We also invest in new seismic data and technology each year. By equipping our geologists and geophysicists with state-of-the-art seismic technology with multiple reprocessing applications, we hope to multiply the number of higher potential exploration prospects we drill without substantially adding to dry hole risk.
 
•  Maintain Flexibility. Because of the volatility of commodity prices and the risks involved in drilling, we remain flexible and may adjust our capital budget throughout the year. We may defer capital projects in order to seize an attractive acquisition opportunity. If certain areas generate higher than anticipated returns, we may accelerate drilling in those areas and decrease capital expenditures elsewhere. We also believe in maintaining a strong balance sheet and using commodity hedging. This will allow us to be more opportunistic in cyclical price environments as well as provide more consistent financial results.
 
•  Equity Ownership and Incentive Compensation. We want our employees to act like owners. To achieve this, we reward and encourage them through equity ownership in Range. As of December 31, 2006, our employees owned equity securities (vested and unvested) which had a market value of over $170.0 million.

Recent acquisitions and dispositions
 
In June 2006 we acquired Stroud Energy, Inc. (“Stroud”) for $171.5 million in cash and 6.5 million shares of our common stock. The transaction was structured as a merger with Stroud shareholders electing to receive either cash, Range stock, or a combination of both cash and stock. Stroud was a private Fort Worth based independent oil and gas company with operations located in the Barnett Shale play in North Texas, the Cotton Valley in East Texas and the Austin Chalk in Central Texas. We estimate the proved reserves attributable to the Stroud properties totaled 171 Bcfe. Over 90% of Stroud’s Barnett Shale acreage is located in the core or expanding core portions of the Barnett Shale play. In the first quarter of 2007, we sold the Austin Chalk properties in Central Texas for proceeds of $82.0 million. Upon closing the Stroud acquisition, we designated the Austin Chalk properties as “properties held for sale.” As a result, the production and associated operations from these properties were excluded from our income from continuing operations. In addition, the production and reserves associated with the properties are excluded from our historical production results and year-end 2006 proved reserves and this sale does not impact those amounts.
 
On March 30, 2007, we sold our Gulf of Mexico properties to a private company for $155 million. The properties included our interests in 37 platforms in water depths ranging from 11 to 240 feet. We did not operate any of the properties. At year-end 2006, we estimate that the properties contained proved reserves of 38 Bcfe, representing 2% of our total proved reserves. As a result of the sale, we expect to record a pre-tax gain of approximately $100 million in the first quarter of 2007.
 
Pending acquisition
 
We recently entered into agreements with certain subsidiaries of Equitable Resources, Inc. (“Equitable”) with respect to a development plan for the Nora field, a gas field located in southwestern Virginia. Closing of the transaction, which is subject to Hart-Scott-Rodino clearance and other customary closing conditions, is anticipated to occur in May 2007. Both companies currently own interests in the Nora field, which currently encompasses approximately 1,600 producing wells and 300,000 gross acres. Under the plan, Equitable and Range will equalize their interests in the Nora field, including the producing wells, undrilled acreage and gathering system. To equalize the interests, we will pay Equitable $315 million, subject to customary adjustments. We have sufficient available capacity under our senior credit facility to complete the acquisition with or without completion of this offering.
 
Upon completion of the transaction, Equitable will continue to operate the producing wells, manage the drilling operations of all future coal bed methane wells and manage the gathering system. We will oversee the drilling of formations below the coal bed methane formation, including the tight gas sand formations, unconventional shales and deeper formations. Currently, the Nora field contains more than 1,150 producing coal bed methane wells and more than 450 producing tight gas sand wells. Given the size of the field, which encompasses approximately 300,000 gross acres, there is potential to drill nearly 6,000 additional coal bed methane wells and tight gas sand wells. Also, the Nora field is located within 10 miles of the Big Sandy shale gas field in Kentucky and West Virginia. Both Range and Equitable believe there is significant unconventional shale gas potential at Nora.

Table of Contents

 
The transaction will allow each company to apply its specific expertise to jointly develop the field more effectively and at a faster pace. Equitable is an industry leader in Appalachian coal bed methane operations having drilled more than 1,100 coal bed methane wells to date. Additionally, Equitable has extensive pipeline assets and expertise throughout the Appalachian Basin in the area of pipeline construction and natural gas transmission. We have drilled thousands of tight gas sand wells in the Appalachian Basin and are actively developing and drilling several unconventional shale gas plays across five basins, including the Appalachian Basin. Although we anticipate that this transaction will close in May 2007, we cannot assure you that the transaction will close at such time or at all.

The offering
 
Common stock offered by Range: 7,000,000 shares (8,050,000 shares if the underwriter’s over-allotment is exercised in full).
 
Common stock projected to be outstanding after the offering: 146,874,482 shares (147,924,482 shares if the underwriter’s over-allotment is exercised in full). Common stock projected to be outstanding does not include options to purchase 8,852,126 shares of common stock outstanding under our stock option plans as of December 31, 2006.
 
We intend to use the net proceeds from this offering to fund a portion of the $315 million consideration required for the Equitable transaction. If the transaction is not consummated, we intend to use a portion of the net proceeds to fund our ongoing drilling program, complementary acquisitions, and general corporate purposes. Pending such uses, the funds will be used to pay down a portion of the outstanding balance on our senior credit facility, which was $385.5 million as of April 2, 2007.

Risk factors
 
You should carefully consider and evaluate all the information included or incorporated by reference in this prospectus supplement and the accompanying prospectus, including the risks described below, before you decide to buy our common stock. Our business, financial condition and results of operations could be materially adversely affected by any of these risks. The trading price of the common stock could decline, and you may lose all or part of your investment. The risks described below are not the only ones facing our company. Additional risks not presently known to us or that we currently deem immaterial individually or in the aggregate may also impair our business operations.
 
This prospectus supplement and documents incorporated by reference also contain forward-looking statements that involve risks and uncertainties, some of which are described in the documents incorporated by reference in this prospectus supplement and the accompanying prospectus. Our actual results could differ materially from those anticipated in these forward-looking statements as a result of various factors, including the risks and uncertainties faced by us described below or incorporated by reference in this prospectus supplement and the accompanying prospectus.
 
Risks related to our business
 
Volatility of oil and natural gas prices significantly affects our cash flow and capital resources and could hamper our ability to produce oil and gas economically
 
Oil and natural gas prices are volatile, and a decline in prices would adversely affect our profitability and financial condition. The oil and natural gas industry is typically cyclical, and prices for oil and natural gas have been highly volatile. Historically, the industry has experienced severe downturns characterized by oversupply and/or weak demand. Higher oil and natural gas prices have contributed to our positive earnings over the last several years. However, long-term supply and demand for oil and natural gas is uncertain and subject to a myriad of factors such as:
 
•  the domestic and foreign supply of oil and gas;
 
•  the price and availability of alternative fuels;
 
•  weather conditions;
 
•  the level of consumer demand;
 
•  the price of foreign imports;
 
•  world-wide economic conditions;
 
•  political conditions in oil and gas producing regions; and
 
•  domestic and foreign governmental regulations.
 
Decreases in oil and natural gas prices from current levels could adversely affect our revenues, net income, cash flow and proved reserves. Significant price decreases could have a material adverse effect on our operations and limit our ability to fund capital expenditures. Without the ability to fund capital expenditures, we will be unable to replace reserves and production.

Table of Contents

 
Hedging transactions may limit our potential gains and involve other risks
 
To manage our exposure to price risk, we, from time to time enter into hedging arrangements, with respect to a significant portion of our future production. The goal of these hedges is to lock in prices so as to limit volatility and increase the predictability of cash flow. These transactions limit our potential gains if oil and natural gas prices rise above the price established by the hedge.
 
In addition, hedging transactions may expose us to the risk of financial loss in certain circumstances, including instances in which:
 
•  our production is less than expected;
 
•  the counterparties to our futures contracts fail to perform under the contracts; or
 
•  a sudden, unexpected event materially impacts oil or natural gas prices or the relationship between the hedged price index and the oil and gas sales price.
 
In the fourth quarter of 2005, due to the trading volatility of NYMEX gas contracts, we experienced larger than usual differentials between actual prices paid at delivery points and NYMEX based gas hedges. Due to this event, certain of our gas hedges no longer qualify for hedge accounting and are marked to market. This may result in more volatility in our income in future periods.
 
Information concerning our reserves and future net reserve estimates is uncertain
 
There are numerous uncertainties inherent in estimating quantities of proved oil and natural gas reserves and their values, including many factors beyond our control. Estimates of proved reserves are by their nature uncertain. Although we believe these estimates are reasonable, actual production, revenues and costs to develop will likely vary from estimates, and these variances could be material.
 
The accuracy of any reserve estimate is a function of the quality of available data, engineering and geological interpretation and judgment, assumptions used regarding quantities of oil and natural gas in place, recovery rates and future prices for oil and natural gas. Actual prices, production, development expenditures, operating expenses and quantities of recoverable oil and natural gas reserves will vary from those assumed in our estimates, and such variances may be material. Any variance in the assumptions could materially affect the estimated quantity and value of the reserves.
 
If oil and natural gas prices decrease or exploration efforts are unsuccessful, we may be required to take write-downs of our oil and natural gas properties
 
In the past, we have been required to write down the carrying value of certain of our oil and natural gas properties, and there is a risk that we will be required to take additional write-downs in the future. This could occur when oil and natural gas prices are low, or if we have downward adjustments to our estimated proved reserves, increases in our estimates of operating or development costs, deterioration in our exploration results or mechanical problems with wells where the cost to redrill or repair does not justify the expense which might occur due to hurricanes.

Accounting rules require that the carrying value of oil and natural gas properties be periodically reviewed for possible impairment. “Impairment” is recognized when the book value of a proven property is greater than the expected undiscounted future net cash flows from that property and on acreage when conditions indicate the carrying value is not recoverable. We may be required to write down the carrying value of a property based on oil and natural gas prices at the time of the impairment review, as well as a continuing evaluation of drilling results, production data, economics and other factors. While an impairment charge reflects our long-term ability to recover an investment, it does not impact cash or cash flow from operating activities, but it does reduce our reported earnings and increases our leverage ratios.
 
For example, based primarily on the poor performance of certain properties acquired in 1997 and 1998 and significantly lower oil and natural gas prices, we recorded impairments of $215.0 million in 1998 and $29.9 million in 1999. At year-end 2001, we recorded an impairment of $31.1 million due to lower year-end prices. At year-end 2004, we recorded an impairment of $3.6 million on an offshore property due to hurricane damage and related production declines. In the third quarter of 2006, we recorded a $2.4 million impairment on an offshore property due to declining oil and gas prices.
 
Our business is subject to operating hazards and environmental regulations that could result in substantial losses or liabilities
 
Oil and natural gas operations are subject to many risks, including well blowouts, craterings, explosions, uncontrollable flows of oil, natural gas or well fluids, fires, formations with abnormal pressures, pipeline ruptures or spills, pollution, releases of toxic natural gas and other environmental hazards and risks. If any of these hazards occur, we could sustain substantial losses as a result of:
 
•  injury or loss of life;
 
•  severe damage to or destruction of property, natural resources and equipment;
 
•  pollution or other environmental damage;
 
•  clean-up responsibilities;
 
•  regulatory investigations and penalties; or
 
•  suspension of operations.
 
As we drill to deeper horizons and in more geologically complex areas, we could experience a greater increase in operating and financial risks due to inherent higher reservoir pressures and unknown downhole risk exposures. As we continue to drill deeper, the number of rigs capable of drilling to such depths will be fewer and we may experience greater competition from other operators.
 
Our operations are subject to numerous and increasingly strict federal, state and local laws, regulations and enforcement policies relating to the environment. We may incur significant costs and liabilities in complying with existing or future environmental laws, regulations and enforcement policies and may incur costs arising out of property damage or injuries to employees and other persons. These costs may result from our current and former operations and even may be caused by previous owners of property we own or lease. Any past, present or future failure by us to completely comply with environmental laws, regulations and enforcement


S-12


Table of Contents

policies could cause us to incur substantial fines, sanctions or liabilities from cleanup costs or other damages. Incurrence of those costs or damages could reduce or eliminate funds available for exploration, development or acquisitions or cause us to incur losses.
 
We maintain insurance against some, but not all, of these potential risks and losses. We may elect not to obtain insurance if we believe that the cost of available insurance is excessive relative to the risks presented. Recently, we have experienced substantial increases in premiums especially in the areas affected by the hurricanes and tropical storms. Insurers have imposed revised limits affecting how much the insurers will pay on actual storm claims plus the cost to re-drill wells where substantial damage has been incurred. Insurers are also requiring us to retain larger deductibles and reducing the scope of what insurable losses will include. Even with the increase in future insurance premiums, coverage will be reduced, requiring us to bear a greater potential risk if our oil and gas properties are damaged. We do not maintain any business interruption insurance. In addition, pollution and environmental risks generally are not fully insurable. If a significant accident or other event occurs that is not fully covered by insurance, it could have a material adverse affect on our financial condition and results of operations.
 
We are subject to financing and interest rate exposure risks
 
Our business and operating results can be harmed by factors such as the availability, terms of and cost of capital, increases in interest rates or a reduction in credit rating. These changes could cause our cost of doing business to increase, limit our ability to pursue acquisition opportunities and place us at a competitive disadvantage. For example, at December 31, 2006, approximately 57% of our debt was at fixed interest rates with the remaining 43% subject to variable interest rates.
 
Many of our current and potential competitors have greater resources than we have and we may not be able to successfully compete in acquiring, exploring and developing new properties
 
We face competition in every aspect of our business, including, but not limited to, acquiring reserves and leases, obtaining goods, services and employees needed to operate and manage our business and marketing oil and natural gas. Competitors include multinational oil companies, independent production companies and individual producers and operators. Many of our competitors have greater financial and other resources than we do.
 
The demand for field services and their ability to meet that demand may limit our ability to drill and produce our oil and natural gas properties
 
Due to current industry demands, well service providers and related equipment and personnel are in short supply. This is causing escalating prices, the possibility of poor services coupled with potential damage to downhole reservoirs and personnel injuries. Such pressures will likely increase the actual cost of services, extend the time to secure such services and add costs for damages due to accidents sustained from the over use of equipment and inexperienced personnel.
 
The oil and natural gas industry is subject to extensive regulation
 
The oil and natural gas industry is subject to various types of regulations in the United States by local, state and federal agencies. Legislation affecting the industry is under constant review for


S-13


Table of Contents

amendment or expansion, frequently increasing our regulatory burden. Numerous departments and agencies, both state and federal, are authorized by statute to issue rules and regulations binding on participants in the oil and natural gas industry. Compliance with such rules and regulations often increases our cost of doing business and, in turn, decreases our profitability.
 
Acquisitions are subject to the risks and uncertainties of evaluating reserves and potential liabilities and may be disruptive and difficult to integrate into our business
 
We could be subject to significant liabilities related to our acquisitions. It generally is not feasible to review in detail every individual property included in an acquisition. Ordinarily, a review is focused on higher valued properties. However, even a detailed review of all properties and records may not reveal existing or potential problems in all of the properties, nor will it permit us to become sufficiently familiar with the properties to assess fully their deficiencies and capabilities. We do not always inspect every well we acquire, and environmental problems, such as groundwater contamination, are not necessarily observable even when an inspection is performed.
 
For example, in 1997, we consummated a large acquisition that proved extremely disappointing. Production from the acquired properties fell more rapidly than anticipated and further development results were below the results we had originally projected. The poor production performance of these properties resulted in material downward reserve revisions. There is no assurance that our recent and/or future acquisition activity will not result in similarly disappointing results.
 
In addition, there is intense competition for acquisition opportunities in our industry. Competition for acquisitions may increase the cost of, or cause us to refrain from, completing acquisitions. Our acquisition strategy is dependent upon, among other things, our ability to obtain debt and equity financing and, in some cases, regulatory approvals. Our ability to pursue our acquisition strategy may be hindered if we are not able to obtain financing on terms acceptable to us or regulatory approvals.
 
Acquisitions often pose integration risks and difficulties. In connection with recent and future acquisitions, the process of integrating acquired operations into our existing operations may result in unforeseen operating difficulties and may require significant management attention and financial resources that would otherwise be available for the ongoing development or expansion of existing operations. Future acquisitions could result in our incurring additional debt, contingent liabilities, expenses and diversion of resources, all of which could have a material adverse effect on our financial condition and operating results.
 
Our pending Equitable transaction may not close as anticipated
 
The closing of the Equitable transaction is subject to Hart-Scott-Rodino clearance and other customary closing conditions. We expect that the transaction will close in May 2007, but we cannot assure you that the transaction will close at such time or at all. This offering is not conditioned on the closing of the Equitable transaction, and we cannot predict the impact on our stock price if the Equitable transaction does not close.

Our success depends on key members of our management and our ability to attract and retain experienced technical and other professional personnel
 
Our success is highly dependent on our management personnel, none of which is currently subject to an employment contract. The loss of one or more of these individuals could have a material adverse effect on our business. Furthermore, competition for experienced technical and other professional personnel is intense. If we cannot retain our current personnel or attract additional experienced personnel, our ability to compete could be adversely affected.
 
Our future success depends on our ability to replace reserves that we produce
 
Because the rate of production from oil and natural gas properties generally declines as reserves are depleted, our future success depends upon our ability to economically find or acquire and produce additional oil and natural gas reserves. Except to the extent that we acquire additional properties containing proved reserves, conduct successful exploration and development activities or, through engineering studies, identify additional behind-pipe zones or secondary recovery reserves, our proved reserves will decline as reserves are produced. Future oil and natural gas production, therefore, is highly dependent upon our level of success in acquiring or finding additional reserves that are economically recoverable. We cannot assure you that we will be able to find or acquire and develop additional reserves at an acceptable cost.
 
New technologies may cause our current exploration and drilling methods to become obsolete
 
The oil and natural gas industry is subject to rapid and significant advancements in technology, including the introduction of new products and services using new technologies. As competitors use or develop new technologies, we may be placed at a competitive disadvantage, and competitive pressures may force us to implement new technologies at a substantial cost. In addition, competitors may have greater financial, technical and personnel resources that allow them to enjoy technological advantages and may in the future allow them to implement new technologies before we can. One or more of the technologies that we currently use or that we may implement in the future may become obsolete. We cannot be certain that we will be able to implement technologies on a timely basis or at a cost that is acceptable to us. If we are not able to maintain technological advancements consistent with industry standards, our operations and financial condition may be adversely affected.
 
Our business depends on oil and natural gas transportation facilities, many of which are owned by others
 
The marketability of our oil and natural gas production depends in part on the availability, proximity and capacity of pipeline systems owned by third parties. The unavailability of or lack of available capacity on these systems and facilities could result in the shut-in of producing wells or the delay or discontinuance of development plans for properties. Although we have some contractual control over the transportation of our product, material changes in these business relationships could materially affect our operations. We generally do not purchase firm transportation on third party facilities and therefore, our production transportation can be interrupted by those having firm arrangements. Federal and state regulation of oil and natural gas production and transportation, tax and energy policies, changes in supply and demand, pipeline pressures, damage to or destruction of pipelines and general economic conditions could adversely affect our ability to produce, gather and transport oil and natural gas.


S-15


Table of Contents

 
The disruption of third-party facilities due to maintenance and/or weather could negatively impact our ability to market and deliver our products. We have no control over when or if such facilities are restored or what prices will be charged. A total shut-in of production could materially affect us due to a lack of cash flow, and if a substantial portion of the production is hedged at lower than market prices, those financial hedges would have to be paid from borrowings absent sufficient cash flow.
 
Our indebtedness could limit our ability to successfully operate our business
 
We are leveraged and our exploration and development program will require substantial capital resources estimated to range from $650 to $825 million per year over the next three years, depending on the level of drilling and the expected cost of services. Our existing operations will also require ongoing capital expenditures. In addition, if we decide to pursue additional acquisitions, our capital expenditures will increase both to complete such acquisitions and to explore and develop any newly acquired properties.
 
The degree to which we are leveraged could have other important consequences, including the following:
 
•  we may be required to dedicate a substantial portion of our cash flows from operations to the payment of our indebtedness, reducing the funds available for our operations;
 
•  a portion of our borrowings are at variable rates of interest, making us vulnerable to increases in interest rates;
 
•  we may be more highly leveraged than some of our competitors, which could place us at a competitive disadvantage;
 
•  our degree of leverage may make us more vulnerable to a downturn in our business or the general economy;
 
•  the terms of our existing credit arrangements contain numerous financial and other restrictive covenants;
 
•  our debt level could limit our flexibility in planning for, or reacting to, changes in our business and the industry in which we operate; and
 
•  we may have difficulties borrowing money in the future.
 
Despite our current levels of indebtedness, we may still be able to incur substantially more debt. This could further increase the risks described above.
 
Any failure to meet our debt obligations could harm our business, financial condition and results of operations
 
If our cash flow and capital resources are insufficient to fund our debt obligations, we may be forced to sell assets, seek additional equity or restructure our debt. In addition, any failure to make scheduled payments of interest and principal on our outstanding indebtedness would likely result in a reduction of our credit rating, which could harm our ability to incur additional indebtedness on acceptable terms. Our cash flow and capital resources may be insufficient for payment of interest on and principal of our debt in the future and any such alternative measures may be unsuccessful or may not permit us to meet scheduled debt service obligations, which could cause us to default on our obligations and impair our liquidity.


S-16


Table of Contents

 
We exist in a litigious environment
 
Any constituent could bring suit or allege a violation of an existing contract. This action could delay when operations can actually commence or could cause a halt to production until such alleged violations are resolved by the courts. Not only could we incur significant legal and support expenses in defending our rights, planned operations could be delayed which would impact our future operations and financial condition. Such legal disputes could also distract management and other personnel from their primary responsibilities.
 
Common stockholders will be diluted if additional shares are issued
 
Since 1998, we have exchanged 31.9 million shares of common stock for debt and convertible securities. The exchanges were made based on the relative market value of the common stock and the debt and convertible securities at the time of the exchange. Also in 2004 and 2005, we sold 33.8 million shares of common stock to finance acquisitions. In 2006, we issued 6.5 million shares of common stock as part of the Stroud acquisition. While the exchanges have reduced interest expense, preferred dividends and future repayment obligations, the larger number of common shares outstanding had a dilutive effect on our existing stockholders. Our ability to repurchase securities for cash is limited by our bank credit facility and our senior subordinated note agreements. In addition, we may issue additional shares of common stock, additional subordinated notes or other securities or debt convertible into common stock, to extend maturities or fund capital expenditures, including acquisitions. If we issue additional shares of our common stock in the future, it may have a dilutive effect on our current outstanding stockholders.
 
Dividend limitations
 
Limits on the payment of dividends and other restricted payments, as defined, are imposed under our bank credit facility and under our senior subordinated note agreements. These limitations may, in certain circumstances, limit or prevent the payment of dividends independent of our dividend policy.
 
Our financial statements are complex
 
Due to accounting rules, our financial statements continue to be complex, particularly with reference to hedging, asset retirement obligations, equity awards, deferred taxes and the accounting for our deferred compensation plan. We expect such complexity to continue and possibly increase.
 
Our stock price may be volatile and you may not be able to resell shares of our common stock at or above the price you paid
 
The price of our common stock fluctuates significantly, which may result in losses for investors. The market price of our common stock has been volatile. From January 1, 2004 to April 13, 2007, the last daily sale price of our common stock reported by the New York Stock Exchange ranged from a low of $6.25 per share to a high of $36.65 per share. We expect our stock to continue to be subject to fluctuations as a result of a variety of factors, including factors beyond our control. These include:
 
•  changes in oil and natural gas prices;


S-17


Table of Contents

 
•  variations in quarterly drilling, recompletions, acquisitions and operating results;
 
•  changes in financial estimates by securities analysts;
 
•  changes in market valuations of comparable companies;
 
•  additions or departures of key personnel; or
 
•  future sales of our stock.
 
We may fail to meet expectations of our stockholders or of securities analysts at some time in the future, and our stock price could decline as a result.
 
Price range of common stock and dividend history
 
Our common stock is listed on the New York Stock Exchange (“NYSE”) under the symbol “RRC.” During 2006, trading volume averaged 1.1 million shares per day. The following table shows the quarterly high and low sale prices, cash dividends declared and volumes as reported on the NYSE composite tape for the past two years (as adjusted for a three-for-two stock split effected December 2, 2005).

Between January 1, 2007 and April 13, 2007, the common stock traded at prices between $25.29 and $36.65 per share and a cash dividend of $0.03 per share was declared in the first quarter of 2007. Our senior subordinated notes are not listed on an exchange, but trade over-the-counter.
 
The payment of dividends is subject to declaration by the Board of Directors and depends on earnings, capital expenditures and various other factors. The bank credit facility and our senior subordinated notes allow for the payment of common and preferred dividends, with certain limitations. The determination of the amount of future dividends, if any, to be declared and paid is at the sole discretion of our board and will depend upon our level of earnings and capital expenditures and other matters that the board of directors deems relevant.

Use of proceeds
 
We estimate that the net proceeds from this offering (after deducting discounts to the underwriters and estimated expenses of the offering) will be approximately $240.9 million. We intend to use the net proceeds from this offering to fund a portion of the $315 million consideration required for the Equitable transaction described under “Summary-Our Business-Pending Acquisition.” The remaining funds required to consummate the Equitable transaction will be funded by our senior credit facility. If the transaction is not consummated, we intend to use a portion of the net proceeds to fund our ongoing drilling program, complementary acquisitions, and general corporate purposes. Pending such uses , the funds will be used to pay down a portion of the outstanding balance on our senior credit facility, which was $385.5 million as of April 2, 2007 . We have sufficient available capacity under our senior credit facility to complete the Equitable transaction without the net proceeds of this offering.

The underwriters are committed to purchase all the common shares offered by us if they purchase any shares. The underwriting agreement also provides that if an underwriter defaults, the purchase commitments of non-defaulting underwriters may also be increased or the offering may be terminated.
 
The underwriters propose to offer the common shares directly to the public at the public offering price set forth on the cover page of this prospectus supplement and to certain dealers at that price less a concession not in excess of $      per share. Any such dealers may resell shares to certain other brokers or dealers at a discount of up to $      per share from the public offering price. After the public offering of the shares, the offering price and other selling terms may be changed by the underwriters.
 
The underwriters have an option to buy up to 1,050,000 additional shares of common stock from us to cover sales of shares by the underwriters which exceed the number of shares specified in the table above. The underwriters have 30 days from the date of this prospectus supplement to exercise this over allotment option. If any shares are purchased with this over-allotment option, the underwriters will purchase shares in approximately the same proportion as shown in the table above. If any additional shares of common stock are purchased, the

We estimate that the total expenses of this offering, including registration, filing and listing fees, printing fees and legal and accounting expenses, but excluding the underwriting discounts and commissions, will be approximately $1.0 million.
 
We have agreed that we will not offer, sell, contract to sell, pledge or otherwise dispose of, directly or indirectly, or file with the Securities and Exchange Commission a registration statement under the Securities Act relating to, any shares of our common stock or securities convertible into or exchangeable or exercisable for any shares of our common stock, or publicly disclose the intention to make any offer, sale, pledge, disposition or filing, without the prior written consent of J.P. Morgan Securities Inc. and Credit Suisse Securities (USA) LLC for a period of 90 days after the date of this prospectus. Notwithstanding the foregoing, if (1) during the last 17 days of the 90-day restricted period, we issue an earnings release or material news or a material event relating to our company occurs; or (2) prior to the expiration of the 90-day restricted period, we announce that we will release earnings results during the 16-day period beginning on the last day of the 90-day period, the restrictions described above shall continue to apply until the expiration of the 18-day period beginning on the issuance of the earnings release or the occurrence of the material news or material event.
 
Our directors and executive officers have entered into lock up agreements with the underwriters prior to the commencement of this offering pursuant to which we and each of these persons or entities, with limited exceptions, for a period of 90 days after the date of this prospectus, may not, without the prior written consent of J.P. Morgan Securities Inc., (1) offer, pledge, announce the intention to sell, grant any option, right or warrant to purchase, or otherwise transfer or dispose of, directly or indirectly, any shares of our common stock (including, without limitation, common stock which may be deemed to be beneficially owned by such directors, executive officers, managers and members in accordance with the rules and regulations of the SEC and securities which may be issued upon exercise of a stock option or warrant) or (2) enter into any swap or other agreement that transfers, in whole or in part, any of the economic consequences of ownership of the common stock, whether any such transaction described in clause (1) or (2) above is to be settled by delivery of common stock or such other securities, in cash or otherwise. Notwithstanding the foregoing, if (1) during the last 17 days of the 90-day restricted period, we issue an earnings release or material news or a material event relating to our company occurs; or (2) prior to the expiration of the 90-day restricted period, we announce that we will release earnings results during the 16-day period beginning on the last day of the 90-day period, the restrictions described above shall continue to apply until the expiration of

the 18-day period beginning on the issuance of the earnings release or the occurrence of the material news or material event. Notwithstanding the foregoing, such individuals, taken as a group, may sell up to an aggregate of 500,000 shares in the indicated period without regard to these restrictions.
 
We have agreed to indemnify the underwriters against certain liabilities, including liabilities under the Securities Act of 1933.
 
In connection with this offering, the underwriters may engage in stabilizing transactions, which involves making bids for, purchasing and selling shares of common stock in the open market for the purpose of preventing or retarding a decline in the market price of the common stock while this offering is in progress. These stabilizing transactions may include making short sales of the common stock, which involves the sale by the underwriters of a greater number of shares of common stock than they are required to purchase in this offering, and purchasing shares of common stock on the open market to cover positions created by short sales. Short sales may be “covered” shorts, which are short positions in an amount not greater than the underwriters’ over allotment option referred to above, or may be “naked” shorts, which are short positions in excess of that amount. The underwriters may close out any covered short position either by exercising their over allotment option, in whole or in part, or by purchasing shares in the open market. In making this determination, the underwriters will consider, among other things, the price of shares available for purchase in the open market compared to the price at which the underwriters may purchase shares through the over allotment option. A naked short position is more likely to be created if the underwriters are concerned that there may be downward pressure on the price of the common stock in the open market that could adversely affect investors who purchase in this offering. To the extent that the underwriters create a naked short position, they will purchase shares in the open market to cover the position.
 
The underwriters have advised us that, pursuant to Regulation M of the Securities Exchange Act of 1934, they may also engage in other activities that stabilize, maintain or otherwise affect the price of the common stock, including the imposition of penalty bids. This means that if the representatives of the underwriters purchase common stock in the open market in stabilizing transactions or to cover short sales, the representatives can require the underwriters that sold those shares as part of this offering to repay the underwriting discount received by them.
 
These activities may have the effect of raising or maintaining the market price of the common stock or preventing or retarding a decline in the market price of the common stock, and, as a result, the price of the common stock may be higher than the price that otherwise might exist in the open market.

Forward-looking statements
 
This prospectus and the documents incorporated by reference in this prospectus contain “forward-looking statements” within the meaning of Section 27A of the Securities Act of 1933 and Section 21E of the Exchange Act. These statements include statements relating to our plans, strategies, objectives, expectations, intentions and adequacy of resources and are made pursuant to the safe harbor provisions of the Private Securities Litigation Reform Act of 1995. In general, all statements other than statements of historical fact are forward-looking statements. These forward-looking statements are based on management’s current belief, based on currently available information, as to the outcome and timing of future events. However, management’s assumptions and our future performance are subject to a wide range of business risks and uncertainties and we cannot assure you that these goals and projections can or will be met. Any number of factors could cause actual results to differ materially from those in the forward-looking statements, including, but not limited to:
 
  •  production variance from expectations,
 
  •  volatility of oil and natural gas prices,
 
  •  hedging results,
 
  •  the need to develop and replace reserves,
 
  •  the substantial capital expenditures required to fund operations,
 
  •  exploration risks,
 
  •  environmental risks,
 
  •  uncertainties about estimates of reserves,
 
  •  competition,
 
  •  litigation,
 
  •  our sources of liquidity,
 
  •  access to capital,
 
  •  government regulation,
 
  •  political risks,
 
  •  our ability to implement our business strategy,
 
  •  costs and results of drilling new projects,
 
  •  mechanical and other inherent risks associated with oil and natural gas production,

  •  weather,
 
  •  availability of drilling equipment,
 
  •  changes of interest rates, and
 
  •  other risks detailed in our filings with the SEC.
 
Reserve engineering is a process of estimating underground accumulations of oil and natural gas that cannot be measured in an exact way. The accuracy of any reserve estimate depends on the quality of available data, the interpretation of such data and price and cost assumptions made by our reserve engineers. In addition, the results of drilling, testing and production activities may justify revisions of estimates that were made previously. If significant, such revisions would change the schedule of any further production and development drilling. Accordingly, reserve estimates may differ from the quantities of oil and natural gas that are ultimately recovered.
 
Although we believe that the expectations reflected in the forward-looking statements are reasonable, we cannot guarantee future results, events, levels of activity, performance or achievements. We do not assume responsibility for the accuracy and completeness of the forward-looking statements.
 
Should one or more of the risks or uncertainties described in this prospectus or the documents we incorporate by reference occur, or should underlying assumptions prove incorrect, our actual results and plans could differ materially from those expressed in any forward-looking statements. Except as required by applicable law, including the securities laws of the United States and the rules and regulations of the SEC, we undertake no obligation to publicly update or revise any forward-looking statements, whether as a result of new information, future events or otherwise.
 
All forward-looking statements express or implied, included in this prospectus and the documents we incorporate by reference and attributable to Range are expressly qualified in their entirety by this cautionary statement. This cautionary statement should also be considered in connection with any subsequent written or oral forward-looking statements that Range or persons acting on its behalf may issue.
 
Use of proceeds
 
Unless we inform you otherwise in a prospectus supplement, we expect to use the net proceeds from the sale of the securities covered by this prospectus that are sold by us for general corporate purposes, which may include but are not limited to reduction or refinancing of debt or other corporate obligations, repurchasing or redeeming our securities, the financing of capital expenditures, acquisitions and additions to our working capital. We may temporarily use the net proceeds received from any offering of securities to repay our senior credit facility or other debt until we can use such net proceeds for the stated purpose. We will not receive any of the proceeds from the sale of securities covered by this prospectus that are sold by selling shareholders.
 
Description of capital stock
 
At June 16, 2006, our authorized and outstanding capital stock consisted of:
 
  •  10,000,000 shares of preferred stock, par value $1.00 per share, of which, no shares are issued and outstanding; and

Special Provision of Delaware Law
 
We are subject to the provisions of Section 203 of the Delaware General Corporation Law. In general, Section 203 prohibits a public Delaware corporation from engaging in a “business combination” with an “interested stockholder” for a period of three years after the date of the transaction in which the person became an interested stockholder, unless:
 
(a) before that person became an interested stockholder, the corporation’s board of directors approved the transaction in which the interested stockholder became an interested stockholder or approved the business combination;
 
(b) upon completion of the transaction that resulted in the interested stockholder’s becoming an interested stockholder, the interested stockholder owns at least 85% of the voting stock outstanding at the time the transaction commenced (excluding stock held by directors who are also officers of the corporation and by employee stock plans that do not provide employees with the right to determine confidentially whether share held subject to the plan will be tendered in a tender or exchange offer); or
 
(c) following the transaction in which that person became an interested stockholder, the business combination is approved by the corporation’s board of directors and authorized at a meeting of stockholders by the affirmative vote of the holders of at least two-thirds of the outstanding voting stock not owned by the interested stockholder.
 
Under Section 203, these restrictions also do not apply to certain business combinations proposed by an interested stockholder following the announcement or notification of one of certain extraordinary transactions involving the corporation and a person who was not an interested stockholder during the previous three years or who became an interested stockholder with the approval of a majority of the corporation’s directors, if that extraordinary transaction is approved or not opposed by a majority of the directors who were directors before any person became an interested stockholder in the previous three years or who were recommended for election or elected to succeed such directors by a majority of such directors then in office. “Business combination” included mergers, assets sales and other transactions resulting in a financial benefit to the stockholder. “Interested stockholder” is a person who, together with affiliates and associates, owns (or, within three years, did own) 15% or more of the corporation’s voting stock.
 
Legal matters
 
Our legal counsel, Vinson & Elkins L.L.P., Dallas, Texas, will pass upon certain legal matters in connection with the offered securities. Any underwriters will be advised about issues relating to any offering by their own legal counsel.
