Exhibit 99.1

Altavista, VA February 11, 2011 — Pinnacle Bankshares Corporation (OTCBB:PPBN), the one-bank holding company (the Company) of First National Bank, (the Bank) (quarterly and 2010 annual consolidated results unaudited) reported today net income after taxes of $63,000 or $0.04 per basic and diluted share for the quarter ended December 31, 2010, and $687,000 or $0.46 per basic and diluted share for the year ended December 31, 2010 compared to net income after taxes of $78,000 or $0.06 per basic and diluted share and net income of $351,000 or $0.24 per basic and diluted share, respectively, for the same periods of 2009.

“We are pleased to report improved earnings in 2010 as net income after taxes rose 96% over 2009 net income after taxes despite the challenging economic environment which led to an increase in our provision for loan losses. The combination of improved margins, stability in noninterest income and a decrease in noninterest expense more than offset the effects of the increase in provision” stated Bryan Lemley, Chief Financial Officer for both the Company and the Bank.

Net interest income was $10,776,000 for the year ended December 31, 2010 compared to $10,004,000 for the year ended December 31, 2009. Net interest income was $2,955,000 for the three months ended December 31, 2010 compared to $2,648,000 for the three months ended December 31, 2009. The net interest margin increased to 3.37% for the year ended December 31, 2010, from 3.23% for the year ended December 31, 2009. Net interest margin increased in the fourth quarter of 2010 to 3.68% as compared to 3.49% in the fourth quarter of 2009 and 3.34% in the third quarter of 2010.

Provision for loan losses was $915,000 in the fourth quarter of 2010 compared to $501,000 in the fourth quarter of 2009. Provision for loan losses was $1,878,000 in 2010 compared with $1,530,000 in 2009.

Noninterest income for the year ended December 31, 2010 decreased $14,000 or less than 1% in 2010 compared to 2009. Noninterest income increased $115,000 or 15% for the three months ended December 31, 2010 compared to the same period of 2009. The increase in noninterest income for the three-month period in 2010 was due to increases in fees from the sale of mortgage loans and investment sales.

Noninterest expense for the year ended December 31, 2010 decreased $134,000 or 1% in 2010 compared to 2009. Noninterest expense increased $34,000 or 1% for the three months ended December 31, 2010 compared to the same period of 2009. The decrease in noninterest expense for the year is attributed primarily to reduced personnel expenses. The increase in the three-month period in 2010 was due to increased commission payments associated with sales of mortgage loans and investments.

Total assets at December 31, 2010 were $337,113,000, up 1% from $332,210,000 at December 31, 2009. The principal components of the Company’s assets at the end of the period were $265,030,000 in net loans, $32,533,000 in cash and cash equivalents and $26,517,000 in securities. During 2010, net loans decreased less than 1% or $874,000 from $265,904,000 at December 31, 2009. Also during 2010, securities increased 32% or $6,361,000.

Total liabilities at December 31, 2010 were $310,631,000, up 1% from $306,359,000 at December 31, 2009, as a result of an increase in savings and NOW accounts of $14,499,000 or 14%. This increase in savings and NOW was

partially offset by a decrease in demand deposits of $1,092,000 or 3% and a decrease in time deposits of $8,572,000 or 5%. The increase in deposits is mainly attributable to the success of our “KaChing! Checking” product which offers rates that are favorable to time deposit rates with the benefit of funds being available for withdrawal.

Total stockholders’ equity at December 31, 2010 was $26,482,000 consisting primarily of $21,918,000 in retained earnings. At December 31, 2009, total stockholders’ equity was $25,851,000.

The allowance for loan losses was $4,037,000 as of December 31, 2010, representing 1.50% of total loans outstanding compared to $3,723,000 or 1.38% of total loans outstanding as of December 31, 2009.

Nonperforming loans (including nonaccruing loans and accruing loans more than 90 days past due) totaled $7,843,000, or 2.92% of total loans, as of December 31, 2010, versus $4,017,000, or 1.49% of total loans, at December 31, 2009. Nonperforming loans increased $792,000 in the fourth quarter of 2010, up from $7,051,000 as of September 30, 2010.
