(5) Net Income Per Share

Basic net income per share excludes dilution and is computed by dividing income available to common stockholders by the weighted-average number of common shares outstanding for the period. Diluted net income per share
reflects the potential dilution that could occur if securities or other contracts to issue common stock were exercised or converted into common stock or resulted in the issuance of common stock that then shared in the earnings of the Company.

The following is a reconciliation of the numerators and denominators of the basic and diluted net income per share computations for the
periods indicated:

(7) Share-based Compensation

The Company has two incentive stock option plans. The 1997 Incentive Stock Plan (the 1997 Plan), pursuant to which the Companys Board of Directors may grant stock options to officers and key
employees, became effective as of May 1, 1997. The 1997 Plan authorizes grants of options to purchase up to 50,000 shares of the Companys authorized, but unissued common stock. Accordingly, 50,000 shares of authorized, but unissued common
stock were reserved for use in the 1997 Plan. All stock options are granted with an exercise price equal to the stocks fair market value at the date of grant. The options expire ten years from the date of grant. At September 30, 2006,
there were 3,200 shares available for grant under the 1997 Plan. A summary of stock option information follows:



|                                                       |  |                 |  |                          |             |                                  |   |                      |  |   |

The 2004 Incentive Stock Plan (the 2004 Plan), pursuant to which the Companys
Board of Directors may grant stock options to officers and key employees, was approved by shareholders on April 13, 2004 and became effective as of May 1, 2004. The 2004 Plan authorizes grants of options to purchase up to 100,000 shares of
the Companys authorized,

but unissued common stock. Accordingly, 100,000 shares of authorized, but unissued common stock were reserved for use in the 2004 Plan. All stock options are
granted with an exercise price equal to the stocks fair market value at the date of grant. The options expire ten years from the date of grant. At September 30, 2006, no options had been granted under the plan, and all 100,000 shares were
available for grant under the 2004 Plan.

The Company adopted Statement of Financial Accounting Standards (SFAS) No. 123R
under the modified prospective method effective January 1, 2006. The Companys adoption of SFAS No. 123R resulted in a total additional expense for the nine months ended September 30, 2006 of approximately $6, net of
tax, relating to the expensing of stock options. Future levels of compensation cost recognized related to share-based compensation awards may be impacted by new awards and/or modification, repurchases and cancellations of existing awards after the
adoption of this standard.

Prior to January 1, 2006, the Company applied the intrinsic value-based method of accounting prescribed by
Accounting Principles Board (APB) Opinion No. 25, Accounting for Stock Issued to Employees, and related interpretations including FASB Interpretation No. 44, Accounting for Certain Transactions Involving Stock Compensation, an
Interpretation of APB Opinion No. 25, to account for its fixed plan stock options. Under this method, compensation expense was recorded on the date of grant only if the current market price of the underlying stock exceeded the exercise
price. SFAS No. 123, Accounting for Stock-Based Compensation, established accounting and disclosure requirements using a fair value-based method of accounting for stock-based employee compensation plans.

Compensation cost has been recognized for the Companys stock options in the accompanying consolidated financial statements for 2006. Had the
Company determined compensation cost based on the fair value of its stock options at the grant date under SFAS No. 123 in 2005, the Companys net income, basic net income per share and diluted net income per share would have decreased to
the pro forma amounts for the interim periods indicated below:

THE COMPANY

Pinnacle
Bankshares Corporation, a Virginia corporation (Bankshares), was organized in 1997 and is registered as a bank holding company under the Bank Holding Company Act of 1956, as amended. Bankshares is headquartered in Altavista, Virginia,
and conducts all of its business activities through the branch offices of its wholly-owned subsidiary bank, The First National Bank of Altavista (the Bank). Bankshares exists primarily for the purpose of holding the stock of its
subsidiary, the Bank, and of such other subsidiaries as it may acquire or establish.

The following discussion supplements and provides
information about the major components of the results of operations and financial

condition, liquidity and capital resources of Bankshares and its subsidiary (collectively the Company). This discussion and analysis should be
read in conjunction with the Companys consolidated financial statements and accompanying notes.

OVERVIEW AND
RESULTS OF OPERATIONS

Total assets at September 30, 2006 were $246,478 up 5.56% from $233,490 at December 31, 2005. The principal
components of the Companys assets at the end of the period were $202,895 in net loans and $25,223 in securities. During the nine-month period ended September 30, 2006, net loans increased 12.21% or $22,084 from $180,811 at
December 31, 2005. The Companys lending activities are a principal source of its income. Also during the nine months, securities decreased 13.80% or $4,038 from December 31, 2005.

Total liabilities at September 30, 2006 were $222,038, up 5.59% from $210,278 at December 31, 2005, primarily as a result of an increase in
time deposits from December 31, 2005 of $6,345 or 5.17% and an increase in demand deposits from December 31, 2005 of $4,035 or 18.41%. The Companys deposits are provided by individuals and businesses located within the communities
the Company serves.

Total stockholders equity at September 30, 2006 was $24,440 including $19,608 in retained earnings and $133
of accumulated other comprehensive losses, which represents net unrealized losses on available-for-sale securities. At December 31, 2005, total stockholders equity was $23,212.

The Company had net income of $1,829 for the nine months ended September 30, 2006, compared with net income of $1,543 for the comparable period in
2005, an increase of 18.54%. The Company had net income of $629 for the three months ended September 30, 2006, compared with net income of $528 for the comparable period in 2005, an increase of 19.13%. The increase in net income when comparing
the nine months ended September 30, 2006 with the nine months ended September 30, 2005 is attributable to a 15.73% increase in net interest income after provision for loan losses and a 0.76% increase in non-interest income. The increase in
net income when comparing the three months ended September 30, 2006 with the three months end September 30, 2005 is attributable to an 16.19% increase in net interest income after provision for loan losses. The results of operations for
the nine months ended September 30, 2006 are not necessarily indicative of the results to be expected for the full year ending December 31, 2006.

Profitability as measured by the Companys return on average assets (ROA) was 1.02% for the nine months ended September 30, 2006, compared to 0.92% for the same period of 2005. Another key indicator of
performance, the return on average equity (ROE) for the nine months ended September 30, 2006 was 10.27%, compared to 9.12% for the nine months ended September 30, 2005.

NET INTEREST INCOME

Net interest income represents the principal source of earnings for the Company. Changes in the volume and mix of interest-earning assets and
interest-bearing liabilities and borrowings, as well as their respective rates and yields, have a significant impact on the level of net interest income.

Net interest income was $6,789 for the nine months ended September 30, 2006 and is attributable to interest income from loans and securities exceeding the cost associated with interest incurred on deposits. Net
interest income was $2,340 for the three months ended September 30, 2006. The net interest margin increased to 4.07% for the nine months ended September 30, 2006, from 3.85% for the nine months ended September 30, 2005. The increase
was caused by an 80 basis point increase in yield on earning assets exceeding the 58 basis point increase in the cost paid for deposits. The loan to deposit ratio increased from 89.32% on September 30, 2005 to 92.84% on September 30, 2006.

Interest income on loans, securities and fed funds sold increased 23.62% and 25.19% for the nine and three months ended September 30,
2006, respectively, compared to the same periods of 2005 due to a higher volume of loans and loans repricing and being originated at higher interest rates in 2006 as a result of the overall higher interest rate environment.

Interest and fees from loans was $10,118 for the nine months ended September 30, 2006, up from $7,801 for the nine months ended September 30,
2005. Interest and fees from loans was $3,624 for the three months ended September 30, 2006, up from $2,805 for the three months ended September 30, 2005. Interest from securities and fed funds sold was $1,256 for the nine months ended
September 30, 2006, down from $1,400 for the nine months ended September 30, 2005. Interest from securities and fed funds sold was $391 for the three months ended September 30, 2006, down from $402 for the three months ended
September 30, 2005.

Interest expense increased 37.48% and 38.54% for the nine and three months ended September 30, 2006,
respectively, compared to the same periods of 2005 due to a higher volume of deposits and the impact of repricing of deposit liabilities at higher interest rates.

NONINTEREST INCOME

Noninterest income increased $14 or 0.76% for the nine months ended September 30, 2006 compared to the same period of 2005. Noninterest income
decreased $27 or 4.12% when comparing the three months ended September 30, 2006 to the same period of 2005. The Companys principal sources of noninterest income are service charges and fees on deposit accounts, particularly transaction
accounts, fees on sales of mortgage loans and commissions from investment and insurance sales.

The Company saw a 13.06% or $32 increase in
commissions and fees as a result of a $35 increase in commissions from investment sales during the first nine months of 2006. Fees on sales of mortgage loans decreased 20.57% or $43 when comparing the nine months ended September 30, 2006 with
the nine months ended September 30, 2005 as total mortgage applications declined.

NONINTEREST EXPENSE

Noninterest expense increased $416 or 7.83%, for the nine months ended September 30, 2006 compared to the same period of 2005. Noninterest expense
increased $124 or 6.77% for the three months ended September 30, 2006 compared to the same period of 2005. The increase in noninterest expense when comparing these periods is primarily attributable to an increase in salary and benefits and
other expenses associated with opening three new facilities. The relocated Timberlake facility opened in May 2006, the Smith Mountain Lake loan production office opened in May 2005 and the new Amherst facility is due to open in November 2006.

ALLOWANCE AND PROVISION FOR LOAN LOSSES

We expensed a provision for loan losses of $240 in the first nine months of 2006 in recognition of managements estimate of risks inherent with lending activities. Among other factors, management considers the
Companys historical loss experience, the size and composition of the loan portfolio, the value and adequacy of collateral and guarantors, non-performing credits, and current and anticipated economic conditions in making its estimate of risk.
There are additional risks of future loan losses that cannot be precisely quantified or attributed to particular loans or classes of loans. Since those risks include general economic trends as well as conditions affecting individual borrowers, the
allowance for loan losses is an estimate. The allowance is also subject to regulatory examinations and determinations as to adequacy, which may take into account such factors as the methodology used to calculate the allowance. The allowance for loan
losses was $1,724 as of September 30, 2006, representing approximately 0.84% of total loans outstanding. Management believes the allowance was adequate as of September 30, 2006 to provide for loan losses inherent in the Companys loan
portfolio. Management evaluates the reasonableness of the allowance for loan losses on a quarterly basis and adjusts the provision as deemed appropriate.

NON-PERFORMING ASSETS AND IMPAIRED LOANS

Non-performing assets, which consist of nonaccrual loans and foreclosed properties, were $330 at September 30, 2006 and $571 at December 31,
2005. Foreclosed property consisted of one property totaling $150 at December 31, 2005. Non-accrual loans were $330 at September 30, 2006 and $421 at December 31, 2005. The Bank had no foreclosed properties as of September 30,
2006. Loans are generally placed in nonaccrual status when the collection of principal and interest is 90 days or more past due, unless the obligation is both well-secured and in the process of collection. A loan is considered an impaired loan when,
based on the then current information and facts, it is probable that we will not be able to collect all amounts due according to the contractual terms of the loan agreement. Impaired loans equaled nonaccrual loans at September 30, 2006.

LIQUIDITY

Liquidity
represents an institutions ability to meet present and future financial obligations through either the sale or maturity of existing assets or the acquisition of additional funds from alternative funding sources. The Companys liquidity is
provided by cash and due from banks, federal funds sold, investments available for sale, managing investment maturities, interest-earning deposits in other financial institutions and loan repayments. The Companys ability to obtain deposits and
purchase funds at favorable rates also affects it liquidity. As a result of the Companys management of liquid assets and its ability to generate liquidity through alternative funding sources, management believes that the Bank maintains overall
liquidity that is sufficient to satisfy its depositors requirements and to meet customers credit needs. The Companys ratio of liquid assets to deposits and short-term borrowings was 13.16% as of September 30, 2006 and 17.62%
as of December 31, 2005. Additional sources of liquidity available to the Company include its capacity to borrow additional funds through correspondent banks. The Company has an established federal funds line with a regional correspondent bank
of $12,220 that had no outstanding balance as of September 30, 2006 and an established line with the FHLB that had $125 outstanding under a total line of $32,042 as of September 30, 2006. The Company derives cash flows from its operating,
investing, and financing activities. Cash flows of the Company are primarily used to fund loans and securities and are provided by the deposits and borrowings of the Company.

CONTRACTUAL OBLIGATIONS

The Company has entered into certain contractual obligations including long-term debt and operating leases. As of September 30, 2006, there have been
no material changes outside the ordinary course of business to the contractual obligations disclosed in Managements Discussion and Analysis in the Companys Quarterly Report on Form 10-Q for the quarter ended March 31,
2006. However, during the quarter ended September 30, 2006, the Company entered into a six month operating lease for a temporary banking unit with a contractual obligation of approximately $13. The Company will use the unit to operate our new
Amherst branch until a permanent branch facility is constructed.

CAPITAL

The Companys financial position at September 30, 2006 reflects liquidity and capital levels currently adequate to fund anticipated future
business expansion. Capital ratios are well above required regulatory minimums for a well-capitalized institution. The assessment of capital adequacy depends on a number of factors such as asset quality, liquidity, earnings performance, and changing
competitive conditions and economic forces. The adequacy of the Companys capital is reviewed by management regularly. Management seeks to maintain a capital structure that will assure an adequate level of capital to support anticipated asset
growth and to absorb potential losses.

Stockholders equity reached $24,440 at September 30, 2006 compared to $23,212 at
December 31, 2005. At September 30, 2006, the Companys leverage ratio (Tier I capital divided by quarterly average assets) was 10.12% compared to 9.88% at December 31, 2005. Each of these ratios exceeded the required minimum
leverage ratio of 4%.

OFF-BALANCE SHEET ARRANGEMENTS

There were no material changes in the Companys off-balance sheet arrangements and commitments from the information provided in the Companys
Annual Report on Form 10-KSB for the year ended December 31, 2005. The Company, in the normal course of business, may at times be a party to financial instruments such as standby letters of credit. Standby letters of credit as of
September 30, 2006 equaled $2,028. Other commitments include commitments to extend credit. Not all of these commitments will be acted upon; therefore, the cash requirements will likely be significantly less than the commitments themselves. As
of September 30, 2006, the Company had unused loan commitments of $64,789, including $51,981 in unused commitments with an original maturity exceeding one year.

NEW BRANCH

The new Amherst office will open in a full-service temporary location at 193 Richmond Highway, Amherst, Virginia in November 2006 with a permanent full-service facility being constructed at 130 South Main Street,
Amherst, Virginia and expected to open in 2007.

CRITICAL ACCOUNTING POLICIES

Certain critical accounting policies affect the more significant judgments and estimates used in the preparation of the consolidated financial statements.
The Companys most critical accounting policy relates to the Companys allowance for loan losses, which reflects the estimated losses resulting from the inability of the Companys borrowers to make required loan payments. If the
financial condition of the Companys borrowers were to deteriorate, resulting in an impairment of their ability to make payments, the Companys estimates would be updated, and additional provisions for loan losses could be required.
Further information regarding the estimates used in determining the allowance for loan losses is contained in the discussions on Allowance and Provision for Loan Losses on page 17 herein and Loans and Allowance for Loan
Losses on page 29 of the Companys 2005 Annual Report to Shareholders.

RECENT ACCOUNTING PRONOUNCEMENTS

In December 2004, the FASB issued SFAS No. 123R, Share-Based Payment. SFAS No. 123R is a revision of SFAS No. 123.
This statement supersedes APB Opinion No. 25 and amends SFAS No. 95, Statement of Cash Flows. SFAS No. 123R eliminates the ability to account for share-based compensation transactions using APB Opinion No. 25 and requires
all share-based payments to employees, including grants of employee stock options, to be recognized in the financial statements using a fair value-based method. SFAS No. 123R permits companies to adopt the recognition requirements using either
a modified prospective method or a modified retrospective method. Under the modified prospective method, compensation cost is recognized in the financial statements beginning with the effective date, based on the
requirements of SFAS No. 123R for all share-based payments granted after that date, and based on the requirements of SFAS No. 123R for all unvested awards granted prior to the effective date of SFAS No. 123R. The modified
retrospective method, has the same requirements as the modified prospective method, but also permits entities to restate financial statements of previous periods based on pro forma disclosures made in accordance with SFAS
No. 123.

The Company adopted SFAS No. 123R under the modified prospective method effective January 1, 2006. The
Company estimates that the adoption of SFAS No. 123R will result in a total additional expense in



20



---

2006 of approximately $9, net of tax, relating to the expensing of stock options. Future levels of compensation cost recognized related to share-based
compensation awards may be impacted by new awards and/or modification, repurchases and cancellations of existing awards after the adoption of this standard.

In February 2006, the FASB issued SFAS No. 155, Accounting for Certain Hybrid Financial Instruments, an amendment of FASB Statements No. 133 and 140. This Statement amends SFAS No. 133,
Accounting for Derivative Instruments and Hedging Activities, and SFAS No. 140, Accounting for Transfers and Servicing of Financial Assets and Extinguishments of Liabilities and resolves issues in Statement No. 133
Implementation Issue No. D1, Application of Statement 133 to Beneficial Interests in Securitized Financial Assets. The provisions of this Statement are effective for all financial instruments acquired or issued after the beginning of an
entitys first fiscal year that begins after September 15, 2006. The adoption of SFAS No. 155 is not expected to have a material impact on the consolidated financial statements of the Company.

In March 2006, the FASB issued SFAS No. 156, Accounting for Servicing of Financial Assets, an amendment of FASB Statement No. 140.This
Statement amends SFAS No. 140,Accounting for Transfers and Servicing of Financial Assets and Extinguishments of Liabilities, a replacement of FASB Statement 125with respect to the accounting for separately recognized servicing assets
and servicing liabilities. The provisions of this Statement are effective for fiscal years beginning after September 15, 2006.The adoption of SFAS No. 156 is not expected to have a material impact on the consolidated financial
statements of the Company.

In September 2006, the FASB issued SFAS No. 157, Fair Value Measurements, which establishes a
framework for measuring fair value in generally accepted accounting principles and expands disclosures about fair value measurements. SFAS No. 157 defines fair value as the price that would be received to sell an asset or paid to transfer a
liability in an orderly transaction between market participants at the measurement date. SFAS No. 157 is effective for financial statements issued for fiscal years beginning after November 15, 2007, and interim periods within those fiscal
years. The Company does not expect the adoption of this new standard to have a material effect on the Companys consolidated results of operations or consolidated financial position.

In September 2006, the FASB issued SFAS No. 158, Employers Accounting for Defined Benefit Pension and Other Postretirement Plans - an
amendment of FASB Statements No. 87, 88, 106, and 132(R), which requires a business entity to recognize the overfunded or underfunded status of a single-employer defined benefit postretirement plan as an asset or liability in its
statement of financial position and to recognize changes in that funded status in comprehensive income in the



21



---

year in which the changes occur. SFAS No. 158 also requires a business entity to measure the funded status of a plan as of the date of its year-end
statement of financial position, with limited exceptions. The provisions of this statement are effective as of the end of the first fiscal year ending after December 15, 2006. We are currently evaluating the impact of this new standard on our
Consolidated Financial Statements.

In June 2006, the FASB issued FASB Interpretation No. 48 (FIN 48), Accounting
for Uncertainty in Income Taxesan interpretation of FASB Statement No. 109, which establishes that the financial statement effects of a tax position taken or expected to be taken in a tax return are to be recognized in the financial
statements when it is more likely than not, based on the technical merits, that the position will be sustained upon examination. FIN 48 is effective for fiscal years beginning after December 15, 2006. The Company does not expect the adoption of
this new standard to have a material effect on the Companys consolidated results of operations or consolidated financial position.

As of November 10, 2006, there are no other new accounting standards issued, but not yet adopted by the Company, which are expected to be applicable to the Companys financial position, operating results or financial statement
disclosures.

QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

MARKET RISK MANAGEMENT

Market risk reflects the risk of economic loss resulting from changes in interest rates and market prices. If the Bank is to achieve its financial
goals, it must effectively manage this risk.

The primary market risk for a bank is interest rate risk and its impact on net interest
income. This exposure results from differences between the amounts of interest earning assets and interest bearing liabilities that reprice within a specified time period as a result of scheduled maturities and repayment and contractual interest
rate changes.

The Banks Asset/Liability Management Committee and the Investment Committee are primarily responsible for establishing
strategies to monitor and control liquidity and interest rate risk. The primary goal for managing interest rate volatility is to maximize net interest income while ensuring liquidity and managing interest rate risk within established guidelines. The
Bank uses static gap analysis, earnings simulation analysis and economic value of equity (net present value estimation) to monitor interest rate risk. Each of these models measures changes in a variety of interest rate scenarios. While each of the
interest rate risk measures have limitations, taken together they represent a reasonably comprehensive view of the magnitude of interest rate risk in the Company, the distribution of risk along the yield curve, the level of risk through time, and
the amount of exposure to changes in certain interest rate relationships. Static gap which measures aggregate repricing is less utilized since it does not effectively measure the earnings impact on the Company and is not addressed here. However,
earnings simulation and economic value models that more effectively measure the earnings impact and are utilized by management on a regular basis are explained below.

EARNINGS SIMULATION ANALYSIS

Management uses earnings simulation analysis to measure interest rate sensitivity and its impact on future earnings. The simulation uses current balance sheet volumes, growth, repricings, changes in mix of assets and liabilities,
prepayments and average rate paid and earned assumptions to project income under multiple interest rate scenarios.

The following table
represents the interest rate sensitivity on net income for the Company using different rate scenarios as of July 31, 2006:



|                     |  |

|+200 basis points    |  | +21.35%               
|+100 basis points    |  | +10.65%

|-200 basis points    |  | -25.71%

ECONOMIC VALUE OF EQUITY SIMULATION

Economic value of equity simulation is used to calculate the estimated fair value of assets and liabilities in different interest rate environments.
Economic values are calculated based on discounted cash flow analysis. The economic value of equity is the economic value of all assets minus the economic value of all liabilities. The change in economic value of equity over different rate
environments is an indication of the longer term repricing risk in the balance sheet. The same assumptions are used in the economic value of equity simulation as in the earnings simulation.

The following chart reflects the change in the economic value by using July 31, 2006 data, over different rate environments with a one-year horizon:



|                     |  |                                                         
|-------------------- |  | --------------------------------------------------------

|-100 basis points    |  | -$2,375                                                 
|-200 basis points    |  | -$5,132                                                 
|-300 basis points    |  | -$8,463                                                 

There have been no material quantitative or qualitative changes in our market risk since this
information was developed using July 31, 2006 data.

The Bank cannot predict future interest rates or their exact effect on net
interest income. Certain limitations are inherent in any analysis. There is no guarantee that the risk management and balance sheet strategies management employs will be effective in periods of rapid rate movements. Furthermore, these analyses do
not reflect actions management might take in response to or in anticipation of changes in interest rates.

Item 4.
CONTROLS AND PROCEDURES

The Company maintains a system of disclosure controls and procedures that is designed
to ensure that material information is accumulated and communicated to management, including the Companys Chief Executive Officer and Chief Financial Officer, as appropriate to allow timely decisions regarding required disclosure. As required,
management, with the participation of the Companys Chief Executive Officer and Chief Financial Officer, evaluated the effectiveness of the design and operation of the Companys disclosure controls and procedures as of the end of the
period covered by this report. Based on this evaluation, the Companys Chief Executive Officer and Chief Financial Officer concluded that the Companys disclosure controls and procedures were operating effectively to ensure that
information required to be disclosed by the Company in reports that it files or submits under the Securities Exchange Act of 1934, as amended, is recorded, processed, summarized, and reported within the time periods specified in the rules and forms
of the SEC.

Because of the inherent limitations in all control systems, no evaluation of controls can provide absolute assurance that the
Companys disclosure controls and procedures will detect or uncover every situation involving the failure of persons within the Company to disclose material information otherwise required to be set forth in the Companys periodic reports.

The Companys management is also responsible for establishing and maintaining adequate internal controls over financial reporting to
provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. There was no change in the Companys
internal control over financial reporting during the most recent fiscal quarter that has materially affected, or is reasonably likely to materially affect, the Companys internal control over financial reporting.
