PART I

Forward-Looking Statements

From time to time, RGC Resources, Inc. (the “Company” or “Resources”) may publish forward-looking statements relating to such matters as anticipated financial performance, business prospects, technological developments, new products, research and development activities and similar matters. The Private Securities Litigation Reform Act of 1995 provides a safe harbor for forward-looking statements. In order to comply with the terms of the safe harbor, the Company notes that a variety of factors could cause the Company’s actual results and experience to differ materially from the anticipated results or other expectations expressed in the Company’s forward-looking statements. These factors are described in Item 1.A below. All of these factors are difficult to predict and many are beyond the Company’s control. Accordingly, while the Company believes its forward-looking statements to be reasonable, there can be no assurance that they will approximate actual experience or that the expectations derived from them will be realized. When used in the Company’s documents or news releases, the words, “anticipate,” “believe,” “intend,” “plan,” “estimate,” “expect,” “objective,” “projection,” “forecast” or similar words or future or conditional verbs such as “will,” “would,” “should,” “could” or “may” are intended to identify forward-looking statements.

Historical Development

The Company was initially incorporated in Virginia on July 31, 1998 for the primary purpose of becoming the holding company for Roanoke Gas Company (“Roanoke Gas”) and its former subsidiaries, Bluefield Gas Company (“Bluefield Gas”) and Diversified Energy Company (“Diversified”). Effective July 1, 1999, Roanoke Gas and its subsidiaries were reorganized into a holding company structure (the “Reorganization”). As a result of the Reorganization: (i) Resources became a holding company owned by the former shareholders of Roanoke Gas; (ii) Resources became the sole owner of the stock of Roanoke Gas, Bluefield Gas and Diversified; (iii) Commonwealth Public Service Corporation, a former subsidiary of Bluefield, merged its natural gas distribution business into Roanoke Gas; (iv) Roanoke Gas and Bluefield Gas continued to operate in the natural gas distribution business as subsidiaries of Resources; and (v) Diversified continued to carry on its nonutility propane business as a subsidiary of Resources.

Roanoke Gas was organized as a public service corporation under the laws of the Commonwealth of Virginia in 1912. The principal service of Roanoke Gas was, and continues to be, the distribution and sale of natural gas. Commencing in 1972, the distribution and sale of propane gas was added to Roanoke Gas’ line of business. The propane business was transferred to Diversified in January 1979. Diversified, which was not a public utility, distributed and sold propane in Southwestern Virginia and Southern West Virginia.

On July 12, 2004, Resources sold the propane assets of its subsidiary, Diversified, d/b/a Highland Propane Company. On June 26, 2005 Resources sold the remaining 10 parcels of property owned by Diversified.

On May 15, 1987, Roanoke Gas, through a series of merger transactions, acquired 100 percent of the outstanding stock of Bluefield Gas, a public service corporation, organized in 1944 under the laws of the State of West Virginia and principally engaged in the distribution of natural gas in Bluefield, West Virginia and surrounding areas, and Gas Service, Inc. (“Gas Service”), a nonpublic utility affiliate (through common directors and shareholders) of Bluefield Gas, which was engaged in the sale of propane in southwestern Virginia and southern West Virginia. After obtaining requisite shareholder approval and the approvals of

3

the Virginia State Corporation Commission (“Virginia Commission”) and the West Virginia Public Service Commission (“West Virginia Commission”), Gas Service was merged into Diversified, and Bluefield Gas became a wholly-owned subsidiary of Roanoke Gas. Prior to the Reorganization, Bluefield Gas owned all

2

of the issued and outstanding stock of Commonwealth, a small Virginia public service corporation organized in 1930 as the subsidiary of a predecessor corporation to Bluefield Gas.

In March 1994, the Highland Energy (formerly Highland Gas Marketing (currently Highland Energy)Marketing) division of Diversified was established to broker natural gas to several industrial transportation customers of Roanoke Gas and Bluefield Gas.

On January 6, 2000, RGC Ventures, Inc. (“RGC Ventures”), a newly created subsidiaryJuly 10, 2006, Diversified entered into an asset purchase and sale agreement for the sale of Resources, was merged with Cox Heating and Cooling, Inc., headquartered in Beckley, West Virginia. Cox Heating and Cooling, Inc. provided sales, installation and service for heating, ventilation, and air conditioning equipment in West Virginia with offices in Beckley and Lewisburg, West Virginia. The new organization operated as a division of RGC Ventures and conducted business as Highland Heating and Cooling (“Highland Heating”).

In September 2001, the Company decided to restructure Highland Heating and Cooling due to poor performance. During fiscal 2002, the Company decided to discontinue the sales of heating and air conditioning equipment and continue the service operations with the intent of merging Highland Heating and Cooling into Diversified to improve efficiencies and reduce costs.

In September 2003, the Company completed the merger of RGC Ventures, Inc. into Diversified.

On November 19, 1999, Resources acquired the assets relating to its energy marketing business to Atmos Energy Marketing, LLC (“Atmos”). The assets sold include the gas supply contracts between Highland Energy and its customers and related business records. The date of GIS/GPS Solutions, Inc. in order to offer geographic mapping technology, combined with database management tools, to developtransfer was set as the date from the first meter read performed for each of the end user friendly, broad based management information systems. In July 2002, the operations function of GIS Resources, Inc. was transferred into Roanoke Gas, and the GIS corporate entity was dissolved.

On October 11, 2000, the information technology department of Resources formed RGC Ventures of Virginia, Inc., to do business as Application Resources, Inc. to provide information technology consulting services to Orcom Solutions, Inc.

On July 12, 2004, Resources sold the propane assets of its subsidiary, Diversified, d/b/a Highland Propane Company, for approximately $28,500,000 in cash to Inergy Propane, LLC. The sale of assets encompassed nearly all of the propane plant assets, including the name “Highland Propane,” customer accounts receivable, propane gas inventory and inventory of propane related materials. Resources realized an after tax gain of approximately $9,500,000 onWith the sale of assets.

On June 26, 2005,both the propane operations in 2004 and the energy marketing operations in August 2006, Resources sold the remaining 10 parcelsactivities consist almost entirely of property owned by Diversified to Inergy Propane, LLC for approximately $750,000. Resources realizednatural gas distribution operations with a pre-tax gainnominal level of approximately $153,000 on the sale of property.

unregulated services.

Resources maintains an integrated natural gas distribution system. Natural gas is purchased from suppliers and distributed to residential, commercial and large industrial users through underground mains and services. Approximately 90.390.4 percent of the Company’s customers are residential, approximately 9.69.5 percent are commercial users, and the remaining percentage is made up of large industrial and transportation customers, who received approximately 3231 percent of the Company’s total annual delivered volume in 20052006 under the Company’s interruptible tariff and transportation gas services.

Exclusive of discontinued operations, Resources’ natural gas distribution business accounted for approximately 82 percent, 81 percent, and 8599 percent of the total revenues excluding discontinued operations, generated by the Company in fiscal years 2006, 2005 2004 and 2003, respectively.2004. Increases or decreases in the cost of natural gas are passed on to

3

customers through the purchased gas adjustment mechanism. Therefore, the Company’s revenues are impacted by changes in gas costs as well as by changes in volume due to weather and economic conditions. Furthermore, higher gas costs, which the Company is able to pass through to customers, may cause customers to conserve or, in the case of industrial customers, to use alternative energy sources.

The Company’s retail sales are seasonal and temperature-sensitive as the majority of the gas sold by Resources is used for heating. For the fiscal year ended September 30, 2005,2006, approximately 55 percent of the Company’s total decatherms (“DTH”) of natural gas sales were made in the four-month period of December through March. (A decatherm is a measurement of heat equivalent to one million BTU where one BTU is equal to the amount of heat required to raise the temperature of one pound of liquid water by one degree Fahrenheit.) Total natural gas deliveries were 10,482,865 DTH, 11,452,388 DTH 11,903,920 DTH and 12,041,19311,903,920 DTH in fiscal years 2006, 2005 2004 and 2003,2004, respectively. The Company’s actual heating degree days in fiscal 20052006 were approximately 9088 percent of the 30-year normal, as compared with approximately 90 percent and 93 percent and 103 percent of the 30-year normal in fiscal years 20042005 and 2003,2004, respectively.

Suppliers

Roanoke Gas Company and Bluefield Gas Company are each served by multiple interstate and intrastate pipelines. Roanoke Gas is served by Columbia Gas Transmission Corporation and Columbia Gulf Transmission Corporation (together “Columbia”), and East Tennessee Natural Gas Company, Tennessee Gas Pipeline, Midwestern Gas Transmission and Virginia Gas Pipeline Company. Bluefield Gas is served by Columbia and Abbs Valley Pipeline. Columbia historically has delivered approximately 6055 percent of Roanoke Gas’ gas supply and 80 percent of Bluefield Gas’ gas supply, while the other pipelines deliver the balance of each companies’ requirements. The rates paid for natural gas transportation and storage services purchased from the interstate pipeline companies are established by tariffs approved by FERC. These tariffs contain flexible pricing provisions, which, in some instances, authorize these transporters to reduce rates and charges to meet price competition.

The Company currently uses long-term (multi-year) contracts to meet its system requirements. The Company’s current suppliers include Sequent Energy and PhoenixDart Energy Sales Company.Corporation. The Company expects its firm supply agreements will be sufficient to supply the total system requirements during the period October 1, 20052006 through September 30, 2006.

2007.

The Company uses summer storage programs to supplement gas supply requirements during the winter months. The Company injects summer gas into its liquefied natural gas storage facility, which is capable of storing up to 220,000 DTH for use during peak demand winter periods. In addition, the Company has contracted for storage reserves from Columbia, Tennessee Gas Pipeline and Virginia Gas Pipeline Company with a combined total of more than three million decatherms of storage capacity. Prior to November 1, 2004, the Company prepaid a portion of its winter requirements under the asset management agreement with a third party under the classification of prepaid gas service. Prepaid gas service represented the Company’s right to receive gas in the future from the asset manager. Effective November 1, 2004, Roanoke Gas and Bluefield Gas each entered into a newutilize Sequent Energy Company as its asset management contract with a different third party. Each new contract is a three-year agreement with similar termsmanager to the expired contract with a key differencemanage their pipeline transportation and storage rights and gas supply inventories and deliveries in addition to being that the Company maintains title to gas in storage. Under the new contract, the balance in prepaid gas service was converted to storage gas inventory with title and ownership maintained by Roanoke Gas and Bluefield Gas.

their primary supplier of natural gas.

Having multiple pipelines at each location, a liquifiedliquefied natural gas facility for peak shaving purposes and a number of underground storage options, the Company believes that it is well positioned to provide adequate gas supply for future customer growth.

Competition

Resources competes with suppliers of other energy sources such as fuel oil, electricity, propane and coal. Competition can be intense among the other energy sources and can be based primarily on price. This is particularly true for industrial applications where sales are at risk to price competition in markets, which may swing to other fuels, depending uponunless environmental regulation restriction on fuel usage.

restrictions limit the usage of other fuels. Rising natural gas prices, compounded by the effect of the damage caused by Hurricane Katrina to natural gas production facilities, appeared to influence consumer behavior as natural gas sales volumes during the winter and early spring appeared to decline relative to weather and to the corresponding periods in 2005 and 2004. Nevertheless, the Company continues to provide service to a majority of the new residential construction market located along or near gas distribution mains in its service area.

The regulated natural gas utilities operate in a monopolistic environment. Roanoke Gas currently holds the only franchises and/or certificates of public convenience and necessity to distribute natural gas in its Virginia service areas. The franchises generally extend for multi-year periods and are renewable by the municipalities. Certificates of public convenience and necessity, which are issued by the Virginia Commission, are of perpetual duration, subject to compliance with regulatory standards.

Roanoke Gas holds the only franchise to distribute natural gas in the cities of Roanoke and Salem and the Town of Vinton. These franchises expire December 31, 2015.

Bluefield Gas holds the only franchise to distribute natural gas in its West Virginia service area. This franchise expires August 23, 2009.

Management anticipates that the Company will be able to renew all of its franchises when they expire. There can be no assurance, however, that a given jurisdiction will not refuse to renew a franchise or will not, in connection with the renewal of a franchise, impose certain restrictions or conditions that could adversely affect the Company’s business operations or financial condition.

Regulation

Roanoke Gas and Bluefield Gas are subject to regulation at federal and state levels. Federally, the interstate gas transmission between Bluefield Gas and Roanoke Gas in Bluefield, Virginia is regulated by FERC. At the state level, the Virginia and West Virginia Commissions regulate Roanoke Gas and Bluefield Gas, respectively. Such regulation includes the prescription of rates and charges at which natural gas is sold to customers, the approval of agreements between or among affiliated companies involving the provision of goods and services, pipeline safety, and certain corporate activities of the Company, including mergers and acquisitions. Both state Commissions also grant certificates of public convenience and necessity to distribute natural gas in their respective states.

Roanoke Gas and Bluefield Gas are further regulated by the municipalities and localities that grant franchises for the placement of gas distribution pipelines and the operation of a gas distribution network within the streets and alleys of the municipalities.

Both Roanoke Gas and Bluefield Gas operated manufactured gas plants (MGPs) as a source of fuel for lighting and heating until the early 1950’s. A by-product of operating MGPs was coal tar, and the potential exists for on-site tar waste contaminants at former plant sites. The extent of contaminants at these sites, if any, is unknown at this time. An analysis at the Bluefield site indicates some soil contamination. The Company, with concurrence of legal counsel, does not believe any events have occurred requiring regulatory reporting. Further, the Company has not received any notices of violation or liabilities associated with environmental regulations related to the MGP sites and is not aware of any off-site

6

contamination or pollution as a result of prior operations. Therefore, the Company has no plans for subsurface remediation at the MGP sites. Should the Company eventually be required to remediate either site, the Company will pursue all prudent and reasonable means to recover any related costs, including insurance claims and regulatory approval for rate case recognition of expenses associated with any work required. A stipulated rate case agreement between the Company and the West Virginia Public Service

5

Commission recognized the Company’s right to defer MGP clean-up costs at the Bluefield site, should any be incurred, and to seek rate relief for such costs. If the Company eventually incurs costs associated with a required clean-up of either MGP site, the Company anticipates recording a regulatory asset for such clean-up costs to be recovered in future rates. Based on anticipated regulatory actions and current practices, management believes that any costs incurred related to this matter will not have a material effect on the Company’s consolidated financial condition or results of operations.

Employees

At September 30, 2005,2006, Resources had 137135 full-time employees. As of that date, 4142 employees, or 3031 percent of the Company’s full-time employees, belonged to the United Steel, Paper Allied-Industrial, Chemical and Forestry, Rubber, Manufacturing, Energy, WorkersAllied-Industrial International Union, AFL-CIO Local No. 2-515. Roanoke Gas Company currently has 3435 of the unionized employees who are currently covered under a collective bargaining agreement with Resources.agreement. The union has been in place at the Company since 1952. The Roanoke Gas collective bargaining agreement will expire on July 31, 2010. Bluefield Gas Company currently has 7 unionized employees who are currently covered under a separate bargaining agreement. The Bluefield Gas collective bargaining agreement will expire on July 4, 2007. Management maintains an amicable relationship with the union.

The Company is exposed to various risks and uncertainties that may affect the operations, performance, development and results of the Company’s business including the following: (i) failure to earn on a consistent basis an adequate return on invested capital; (ii) increasing expensesability to retain and labor costsattract professional and labor availability;technical employees; (iii) price competition from alternative fuels; (iv) volatility in the price and availability of natural gas; (v) uncertainty in the projected rate of growth of natural gas requirements in the Company’s service area; (vi) general economic conditions both locally and nationally; (vii) increases in interest rates; (viii) increased customer delinquencies and conservation efforts resulting from high fuel costs and/or colder weather; (ix) developments in electricity and natural gas deregulation and associated industry restructuring; (x) variations in winter heating degree-days from normal; (xi) changes in environmental requirements, pipeline operating requirements and cost of compliance; (xii) impact of potential increased governmentalregulatory oversight and compliance requirements costs due the Sarbanes-Oxley law;to financial, environmental, safety and system integrity laws and regulations; (xiii) failure to obtain timely rate relief for increasing operationoperating or gas costs from regulatory authorities; (xiv) ability to raise debt or equity capital; (xv) impact of uncertaintiesterrorism; (xvi) volatility in the Middle Eastactuarially determined benefit costs: and related terrorism issues, and (xvi)(xvii) new accounting standards issued by the Financial Accounting Standards Board, which could change the accounting treatment for certain transactions.

The most significant risk factors include the following:

High natural gas prices:

The combination of the damage to natural gas production and transportation facilities attributable to recent hurricanesHurricane Katrina in 2005 and increasing demandsdemand for natural gas for electric generation have resulted in a significant rise in natural gas prices.prices during this past winter. Since then, the price of natural gas has declined; however, prices still remain higher than historical levels. If natural gas prices remain at these unprecedentedreturn to the higher levels experienced during

7

this past winter season, the Company may encounter a more than proportionate increase in bad debts and continued sales volume reductions attributable to conservation or customers converting to other energy or heating fuels.

Warm winter weather:

The Company’s business is seasonal in nature and relies upon the sale of natural gas primarily as a heating fuel. In addition, the Company’s non-gas margin rates are established based upon projected sales assuming

weather utilizing a trailing 30-year period. In years where winter weather is warmer than the trailing 30 year30-year period, the demand forcustomers use less natural gas as a heating fuel declines resultingfuel. This results in reduced sales and lower margins. The risk of warm winter weather has been partially mitigated due to the inclusion of a weather normalization adjustment (“WNA”(the “WNA”) factor as part of Roanoke Gas Company’s rate structure.structure has partially mitigated the risk of a warm winter. The WNA factor operates based on a weather occurrence band around the most recent 30-year temperature average. The weather band provides approximately a 6 percent range around normal weather, wherebyso if the number of heating-degree days fall withinheating degree-days is less than approximately 6 percent above or below the 30-year average, no adjustments are made. However, ifIf the number of heating degree-days wereis more than 6 percent below the 30-year average, the WNA factor allows the Company wouldto add a surcharge to firm customer bills (those customers not subject to service interruption) equal to the equivalent margin lost below the approximate 6 percent deficiency. Likewise, if the number of heating-degree days were more than 6 percent above the 30-year average, the Company would credit firm customer bills equal to the excess margin realized above the 6 percent heating degree-days. The measurement period in determining the weather bandfor these measurements extends from April through March with any adjustment to be made to customer bills in late spring.

The property contained within the “Utility Plant” designation on the Company’s consolidated balance sheet consists of intangible plant, storage plant, transmission plant, distribution plant and general plant as categorized by natural gas utilities. Transmission and distribution plant represent almost 87%87 percent of the total investment in plant. The Company has approximately 1,1401,150 miles of transmission and distribution pipeline to serve the Company’s 59,00059,300 customers in the Company’s service territories. All “Utility Plant” is owned by either Roanoke Gas or Bluefield Gas.

Roanoke Gas owns and operates six metering stations through which it measures and regulates the gas being delivered by its suppliers. Roanoke Gas also owns two metering stations located on property owned by East Tennessee Natural Gas Company. These stations are located andat various points throughout the Company’s distribution system.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

Board of Directors and Stockholders

RGC Resources, Inc.

Roanoke, Virginia

We have audited, before the effects of the retrospective adjustments for the discontinued operations of the energy marketing division and change in reportable segments discussed in Note 2 to the consolidated financial statements, the consolidated balance sheet of RGC Resources, Inc. and subsidiaries (the “Company”) as of September 30, 2005, and the related consolidated statements of income and comprehensive income, stockholders’ equity and cash flows for each of the years ended September 30, 2005 and 2004 (the 2005 and 2004 consolidated statements of income and comprehensive income and of cash flows before the effects of the retrospective adjustments discussed in Note 2 to the consolidated financial statements are not presented herein). These financial statements are the responsibility of the Company’s management. Our responsibility is to express an opinion on these financial statements based on our audits.

We conducted our audits in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement. The Company is not required to have, nor were we engaged to perform, an audit of its internal control over financial reporting. Our audits included consideration of internal control over financial reporting as a basis for designing audit procedures that are appropriate in the circumstances, but not for the purpose of expressing an opinion on the effectiveness of the Company’s internal control over financial reporting. Accordingly, we express no such opinion. An audit also includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements, assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement presentation. We believe that our audits provide a reasonable basis for our opinion.

In our opinion, such 2005 and 2004 consolidated financial statements, before the effects of the retrospective adjustments for the discontinued operations of the energy marketing division and change in reportable segments discussed in Note 2 to the consolidated financial statements, present fairly, in all material respects, the financial position of the Company as of September 30, 2005, and the results of its operations and its cash flows for the years ended September 30, 2005 and 2004 in conformity with accounting principles generally accepted in the United States of America.

As discussed in Note 2 to the financial statements, on July 12, 2004, the Company sold substantially all of the assets of its subsidiary, Diversified Energy Company, d/b/a Highland Propane Company (“Highland Propane”), and on June 24, 2005 sold all remaining assets of Highland Propane.

We were not engaged to audit, review, or apply any procedures to the retrospective adjustments for the discontinued operations of the energy marketing division and change in reportable segments discussed in Note 2 to the consolidated financial statements and, accordingly, we do not express an opinion or any other form of assurance about whether such retrospective adjustments are appropriate and have been properly applied. Those retrospective adjustments were audited by other auditors.
