Exhibit 99.1

Altavista, VA (April 30, 2010) — Pinnacle Bankshares Corporation (OTCBB:PPBN), the one-bank holding company (the “Company”) of First National Bank (the “Bank”)(first quarter 2010 consolidated results unaudited) reported today net income after taxes of $183,000 or $0.12 income per basic share and diluted share for the quarter ended March 31, 2010 compared to a net loss after taxes of $219,000 or $0.15 loss per basic share and diluted share for the same period in 2009.

Profitability as measured by the Company’s annualized return on average assets (“ROA”) was 0.22% for the quarter ended March 31, 2010, compared to (0.27)% for the same period in 2009. Annualized return on average equity (“ROE”) for the quarter ended March 31, 2010 was 2.82%, compared to (3.54) % for the same period in 2009.

“We are pleased to see better returns in the first quarter of 2010 compared to 2009 due to an increase in the net interest margin and improvements in net chargeoffs leading to less provision expense,” commented Bryan M. Lemley, Chief Financial Officer for both Pinnacle Bankshares and First National Bank.

Net interest income was $2,563,000 for the three months ended March 31, 2010 compared to $2,368,000 for the three months ended March 31, 2009. The net interest margin increased to 3.38% for the three months ended March 31, 2010, from 3.17% for the same period in 2009. Over the past twelve months, rates paid to fund earning assets have fallen at a faster pace than the yield received on earnings assets.

Interest income on loans and securities decreased 6% in the first quarter of 2010 compared to the first quarter of 2009 as net loan volume decreased by $10,766,000 since March 31, 2009, while the yield on loans and securities decreased by 38 basis points in the same time period. Interest income was $4,084,000 for the three-month period ended March 31, 2010, down from $4,325,000 for the same period in 2009.

Interest expense decreased 22% in the first quarter of 2010 compared to the first quarter of 2009 as deposits have increased by $6,567,000 in the past twelve months and the rate paid to fund earning assets has fallen by 59 basis points in the same time period.

Provision for loan losses was $263,000 in the first quarter of 2010 compared to $774,000 in the same period of 2009.

Noninterest income decreased $20,000 or 3% for the three-month period ended March 31, 2010 compared to the same period of 2009. The decrease from 2009 was due mainly to a $23,000 or 23% decrease in fees on sales of mortgage loans.

Noninterest expense increased $61,000 or 2% for the three-month period ended March 31, 2010 compared to the same period of 2009. The increase in noninterest expense for the three-month period is attributed primarily to the $74,000 increase in FDIC premiums and expenses associated with our Rustburg branch that opened in February 2009. The increases in noninterest expense were offset by a $41,000 decrease in salary and employee benefits due to fewer employees and lower costs to fund retirement benefits.

Total assets at March 31, 2010 were $331,863,000, essentially unchanged from December 31, 2009. The principal components of the Company’s assets at the

end of the period were $264,416,000 in net loans and $18,293,000 in securities. During the three-month period ended March 31, 2010, net loans decreased 1% or $1,488,000 from $265,904,000 at December 31, 2009. Also during the three-month period, securities decreased 9% or $1,863,000 from December 31, 2009. Total liabilities at March 31, 2010 were $305,798,000, essentially unchanged from December 31, 2009.

Total stockholders’ equity at March 31, 2010 was $26,065,000, representing an equity to assets ratio of 7.80%. Tangible equity totaled $25,526,000 as of the same date, or 7.70% of tangible assets. None of the Company’s capital includes TARP funds. Tangible book value per share was $17.19 as of March 31, 2010. The Bank continues to exceed all minimums to satisfy “well capitalized” regulatory status. At December 31, 2009, total stockholders’ equity was $25,851,000.

The allowance for loan losses was $3,771,000 as of March 31, 2010, representing approximately 1.41% of total loans outstanding compared to an allowance for loan losses of $3,723,000 as of December 31, 2009, representing approximately 1.38% of total loans outstanding.
