Exhibit 99.1

Altavista, VA July 30, 2010- Pinnacle Bankshares Corporation (OTCBB:PPBN), the one-bank holding company (the Company) of First National Bank (the Bank), today reported its quarterly consolidated unaudited results. Net income was $67,000 or $0.05 per basic and diluted share for the quarter ended June 30, 2010, and $250,000 or $0.17 per basic and diluted share for the six months ended June 30, 2010 compared to net income of $255,000 or $0.17 per basic and diluted share and $36,000 or $0.02 per basic and diluted share, respectively, for the same periods of 2009.

Profitability as measured by the Company’s annualized return on average assets (“ROA”) was 0.15% for the six months ended June 30, 2010, compared to 0.02% for the same period in 2009. Annualized return on average equity (“ROE”) for the six months ended June 30, 2010 was 1.92%, compared to 0.29% for the same period in 2009.

“Lower returns in the second quarter compared to the first quarter were driven by an increase in our loan loss provision as asset quality in this economic downturn continues to receive our priority attention. However, we are pleased to show better returns for the first half of 2010 compared to 2009 due to an improved interest margin and lower operating costs,” commented Bryan M. Lemley, Chief Financial Officer for both the Company and the Bank.

Net interest income was $5,165,000 for the six months ended June 30, 2010 compared to $4,817,000 for the six months ended June 30, 2009. Net interest income was $2,602,000 for the three months ended June 30, 2010 compared to $2,449,000 for the three months ended June 30, 2009.

The net interest margin increased to 3.34% for the six months ended June 30, 2010, from 3.18% for the six months ended June 30, 2009, and was 3.32% versus 3.21% for the second quarter of 2010 and 2009, respectively. Over the past twelve months, rates paid to fund earning assets have fallen at a faster pace than the yield received on earning assets.

Interest income decreased 5% for both the six and three months ended June 30, 2010 compared to the same periods of 2009, as net loans outstanding decreased by $11,743,000 since June 30, 2009 while the yield on loans and securities decreased by 40 basis points in the same time period.

Interest expense decreased 21% and 20% for the six and three months ended June 30, 2010, respectively, compared to the same periods of 2009, as deposits have increased by $7,635,000 in the past twelve months while the cost of deposits has fallen by 56 basis points in the same time period.

Noninterest income decreased $96,000 or 12% for the three months ended June 30, 2010 compared to the same period of 2009. The decreases from 2009 were due to a $127,000 and $104,000 decrease in fees on sales of mortgage loans in the first six months and second quarter of 2010, respectively, compared to the same periods in 2009.

Noninterest expense decreased $53,000 or less than 1% for the six months ended June 30, 2010 compared to the same period of 2009. Noninterest expense decreased $114,000 or 4% for the three months ended June 30, 2010 compared to

the same period of 2009. The decreases in noninterest expense were attributable to a $108,000 decrease in salary and employee benefits due to fewer employees and lower costs to fund retirement benefits.

Total assets at June 30, 2010 were $334,608,000, up less than 1% from $332,210,000 at December 31, 2009.
