Altavista, VA (January 31, 2006) — Pinnacle Bankshares Corporation (OTCBB:PPBN), the one-bank holding company (the “Company”) of The First National Bank of Altavista (quarterly and 2006 annual consolidated results unaudited) reported today net income after taxes of $583,000 or $0.41 per basic share for the quarter ended December 31, 2006 and $2,412,000 or $1.66 per basic share for the year ended December 31, 2006 compared to net income after taxes of $564,000 or $0.39 per basic share and $2,107,000 or $1.44 per basic share for the same periods of 2005.

The 14.48% increase in net income after taxes for the year ended December 31, 2006 was driven primarily by a 15.14% increase in net interest income that resulted from an increase in loan volume and net interest margin.

Profitability as measured by the Company’s return on average assets (ROA) was 1.00% for the year ended December 31, 2006, compared to 0.94% for 2005. Another key indicator of performance, the return on average equity (ROE) for the year ended December 31, 2006 was 10.11%, compared to 9.29% for the year ended December 31, 2005.

“We are extremely pleased that our recent growth has lead to net income for 2006 being the highest in the Company’s history”, stated Rob Gilliam, President and CEO for both Pinnacle Bankshares and First National Bank.

Net interest income was $9,192,000 for the year ended December 31, 2006. Net interest income was $2,403,000 for the three months ended December 31, 2006. The net interest margin increased to 4.05% for the year ended December 31, 2006 from 3.83% for the year ended December 31, 2005. The increase in net interest margin is due primarily to the upward repricing of the adjustable rate credits in the bank’s loan portfolio.

Noninterest income increased $104,000 or 4.34% for the year ended December 31, 2006 compared to 2005. Noninterest income increased $90,000 or 16.22% when comparing the three months ended December 31, 2006 to the same period of 2005. The increases from the 2005 levels were primarily due to a 13.86% increase in commissions and fees as a result of an increase in commissions from investment product sales in 2006.

Noninterest expense increased $659,000 or 9.20%, for the year ended December 31, 2006 compared to 2005. Noninterest expense increased $243,000 or 13.11% for the three months ended December 31, 2006 compared to the same period of 2005. The increase in noninterest expense in 2006 is attributed primarily to the effect of overall growth of the Company on personnel expenses and fixed asset costs.

Total assets at December 31, 2006 were $256,238,000, up 9.74% from $233,490,000 at December 31, 2005. The principal components of the Company’s assets at the end of the year were $14,586,000 in cash and cash equivalents, $24,866,000 in securities and $207,861,000 in net loans. During the year ended December 31, 2006, gross loans increased 14.71% or $26,907,000.

Total liabilities at December 31, 2006 were $231,929,000, up 10.30% from $210,278,000 at December 31, 2005, with the increase reflecting an increase in total deposits of $21,571,000 or 10.31%. Noninterest-bearing demand deposits increased $1,717,000 or 7.84%, savings and NOW accounts increased $5,137,000 or 7.94% and time deposits increased $14,717,000 or 12.00%.

Total stockholders’ equity at December 31, 2006 was $24,309,000 including $19,972,000 in retained earnings. At December 31, 2005, total stockholders’ equity was $23,212,000.
