nature, necessary to present fairly the financial position as of March 31, 2005 and the results of operations and cash flows for the three-month periods ended March 31, 2005 and 2004.



These interim period consolidated financial statements and financial information should be read in conjunction with the
consolidated financial statements and notes thereto included in Pinnacle Bankshares Corporations 2004 Annual Report to Shareholders and additional information supplied in the 2004 Form 10-KSB.



The results of operations for the interim period ended March 31, 2005 are not
necessarily indicative of the results to be expected for the full year ending December 31, 2005.



The Company has a single reportable segment for purposes of segment reporting.



(2) Cash and Cash Equivalents



For purposes of reporting cash flows, cash and cash equivalents include cash on hand, amounts due from banks, interest-bearing deposits, and federal funds
sold.

fair values for securities at March 31, 2005, are shown in the table below. As of March 31, 2005, securities with amortized costs of $4,466 and fair values of $4,546 were pledged as collateral for public deposits.

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

(7) Stock Options



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, was 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 are 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. At March 31, 2005, there were 3,100 shares available for grant under the 1997 Plan.



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 are 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 Company applies 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 is 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. As allowed by SFAS No. 123, the Company has
elected to continue to apply the intrinsic value-based method of accounting described above, and has adopted the disclosure requirements of SFAS No. 123, as amended by SFAS No. 148, Accounting for Stock-Based Compensation  Transition and
Disclosure, an amendment of FASB Statement No. 123.



No
compensation cost has been recognized for the Companys stock options in the accompanying consolidated financial statements. Had the Company determined compensation cost based on the fair value of its stock options at the grant date under SFAS
No. 123, 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



Total assets at March 31, 2005 were
$224,670 up 2.21% from $219,813 at December 31, 2004. The principal components of the Companys assets at the end of the period were $33,333 in securities and $160,442 in net loans. During the three month period ended March 31, 2005, net loans
increased 1.00% or $1,596 from $158,846 at December 31, 2004. The Companys lending activities are a principal source of its income. Also during the three-month period, securities decreased 2.60% or $891 from December 31, 2004.



Total liabilities at March 31, 2005 were $202,432, up 2.44% from $197,606 at
December 31, 2004, primarily as a result of an increase in savings and NOW accounts from December 31, 2004 of $3,883 or 6.49% and an increase in demand deposits from December 31, 2004 of $1,321 or 6.68%. The Companys deposits are provided by
individuals and businesses located within the communities the Company serves.



Total stockholders equity at March 31, 2005 was $22,238, including $17,272 in retained earnings and $13 of accumulated other comprehensive income, which represents net unrealized gains on available-for-sale
securities. At December 31, 2004, total stockholders equity was $22,207.



The Company had net income of $477 for the three months ended March 31, 2005, compared with net income of $440 for the comparable period in 2004, an increase of 8.41%. This increase in net income was primarily due to
an increase in net interest income after provision for loan losses as interest income increased by $276 and the provision for loan losses decreased by $48 over the same time period in 2004.



Profitability as measured by the Companys return on average assets
(ROA) was 0.86% for the three months ended March 31, 2005, up from 0.85% for the same period of 2004. Another key indicator of performance, the return on average equity (ROE), for the three months ended March 31, 2005 was 8.59%, up from 8.14% for
the three months ended March 31, 2004.



The results of
operations for the three-month period ended March 31, 2005 are not necessarily indicative of the results to be expected for the full year ending December 31, 2005.

NET INTEREST INCOME



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



Net interest income was $1,880 for the three months ended March 31, 2005 compared to $1,808 for the three months ended March 31, 2004 and is attributable
to interest income from loans and securities exceeding the cost associated with interest paid on deposits. The net interest margin decreased to 3.76% for the three months ended March 31, 2005, from 3.78% for the three months ended March 31, 2004.
The decrease was attributable to the upward repricing of deposits at a faster rate than the Companys loans as time deposits, the highest paying deposit category, have increased 11.42% from March 31, 2004 to March 31, 2005.



Interest income on loans and securities increased 10.39% in the first quarter
of 2005 compared to the first quarter of 2004 due to the impact of upward repricing variable rate loans as the prime rate has increased 1.75% since March 31, 2004. Interest and fees on loans was $2,431 for the three-month period ended March 31,
2005, up from $2,167 for the same period in 2004.



Interest
expense on deposits increased 24.03% in the first quarter of 2005 compared to the first quarter of 2004 due to the impact of repricing of deposit liabilities during 2004 and the first quarter of 2005 noted above.



NON-INTEREST INCOME



Non-interest income decreased $21 or 3.68% for the three-month period ended March 31, 2005 compared to the same period of
2004. The Companys principal sources of non-interest income are service charges and fees on deposit accounts, particularly transaction accounts, and fees on sales of mortgage loans. The decrease from 2004 was due to a $40 decrease in fees on
sales of mortgage loans. The decrease in fees on the sale of mortgage loans is due to a slight increase in mortgage rates, fewer refinances and the lack of growth in the mortgage loan market in the first quarter of 2005. The Company did experience a
12.50% increase in commissions from investment and insurance sales through BI investments and Bankers Insurance as another Investment Broker was added to the Companys staff.

NON-INTEREST EXPENSE



Non-interest expense increased $41 or 2.47%, for the three-month period ended March 31, 2005 compared to the same period of 2004. The increase in
non-interest expense when comparing the two periods is primarily attributable to the growth of the Companys personnel expenses and a 28.89% increase in furniture and equipment. The increase in the furniture and equipment expense is associated
with depreciation and service cost of equipment at the new Forest office opened in August 2004 and improvements to our core system software in June 2004.



ALLOWANCE AND PROVISION FOR LOAN LOSSES



We expensed a provision for loan losses of $60 in the first three months of 2005 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 $1,482 as of March 31, 2005, representing approximately 0.92% of total loans outstanding. Management believes the allowance was adequate as of March 31, 2005 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 $317 at March 31, 2005 and $343 at December 31, 2004. Foreclosed property consists of one property totaling $150 as of March 31, 2005 and December 31, 2004. Nonaccrual loans were $167 at March 31, 2005 and $189 at December 31, 2004.
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 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 March 31, 2005.

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 23.45% as of March 31, 2005 compared to 22.58% as of December 31, 2004. Additional sources of liquidity available to the Company include its capacity to borrow
additional funds through correspondent banks. 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.



CAPITAL



The Companys financial position at March 31, 2005 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 $22,238 at March 31, 2005 compared to $22,207 at December 31, 2004. At March 31, 2005, the Companys leverage ratio
(Tier I capital divided by quarterly average assets) was 9.74% compared to 9.85% at December 31, 2004. 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, 2004. The Company, in the normal course of business, may at times be a

##### Table of Contents

party to financial instruments such as standby letters of credit. Standby letters of credit as of March 31, 2005 equaled
$1,198. 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 March 31, 2005, the Company
had unused loan commitments of $49,172, including $42,198 in unused commitments with an original maturity exceeding one year.



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 15 herein and Loans and Allowance for Loan
Losses on page 28 of the Companys 2004 Annual Report to Shareholders.



RECENT ACCOUNTING PRONOUNCEMENTS



In December 2004,
the FASB issued SFAS No. 123 (R), Share-Based Payment. SFAS No. 123 (R) 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. 123 (R) 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. 123 (R) is effective for public companies that file as small business issuers at the beginning of the next fiscal period that begins after December 15, 2005. The impact of SFAS No. 123 (R) on the Companys
consolidated financial statements is currently being evaluated.



In March 2005, the SEC released Staff Accounting Bulletin No. 107, Share-Based Payment, (SAB 107). SAB 107 express views of the SEC staff regarding the application of Statement of Financial Accounting Standards Statement No. 123
(revised 2004), Share-Based Payment (Statement 123R). Among other things, SAB 107 provides interpretive guidance related to the interaction between Statement 123R and certain SEC rules and regulations, as well as provides the staffs views
regarding the valuation of share-based payment arrangements for public companies



As of March 31, 2005, 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.

Item 3. 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 control over financial reporting and control of the Companys assets 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 or control over its assets.
