             PINNACLE BANCSHARES ANNOUNCES RESULTS FOR THIRD QUARTER


         Jasper, Alabama (November 9, 2005) - Robert B. Nolen, Jr., President
and Chief Executive Officer of Pinnacle Bancshares, Inc. (AMEX:PLE), today
announced Pinnacle's third quarter results of operations. For the three months
ended September 30, 2005, net income was $462,000, compared with net income of
$309,000 for the three months ended September 30, 2004. Net interest income
after the provision for loan losses for the three months ended September 30,
2005, was $1,593,000, compared with $1,639,000 in the same period last year.

         For the nine months ended September 30, 2005, net income was
$1,194,000, compared with $1,281,000 for the nine months ended September 30,
2004. Net interest income after the provision for loan losses for the nine
months ended September 30, 2005 was $4,697,000, compared with $4,935,000 in the
same period last year.

         Basic and diluted earnings per share for the three months ended
September 30, 2005 were $0.30 and $0.29 per share, respectively, compared to
$0.20 per share for each of basic and diluted earnings per share during the same
period last year. For the nine months ended September 30, 2005, basic and
diluted earnings were $0.77 and $0.76 per share, respectively, compared to $0.80
and $0.82, respectively, for the same period last year.

         Mr. Nolen attributed the decreases in net interest income in part to
Pinnacle's decreasing net interest margin due to increases in market interest
rates. As market rates continued to increase during the nine months ended
September 30, 2005, the Company's cost of funds increased more rapidly than
rates on investments. For the nine months ended September 30, 2005, the
Company's interest expense was $3,337,000, compared to $2,597,000 for the nine
months ended September 30, 2004, an increase of 28.5%. As a result, the
Company's net interest margin was 3.42% and 3.45% for the three and nine months
ended September 30, 2005, respectively, compared to 3.71% and 3.70% for the
three and nine months ended September 30, 2004, respectively. Mr. Nolen
commented that if interest rates continue to increase, he expects that the
margin will continue to decline. The Company is contemplating strategies to
increase its net interest margin including the sale of certain
available-for-sale securities.

         Mr. Nolen noted that noninterest income increased $363,000, or 183.4%,
and $220,000, or 17.5%, in the three and nine months ended September 30, 2005.
These increases were primarily attributed to decreases in the loss on sale of
securities available-for-sale.

         Mr. Nolen observed that, in comparison to the first nine months of
2004, fees and service charges on deposit accounts decreased approximately
$70,000 primarily due to a decline in insufficient funds fees, and net gains
from loan sales declined $95,000 due to a 14.0% decrease in originations of
mortgage loans held for sale.

         Mr. Nolen also noted significant improvement in the Company's asset
quality ratios. As a percent of total loans, nonperforming loans were 0.13% at
September 30, 2005, compared to 0.72% at September 30, 2004. As a percent of
total assets, nonperforming assets were 0.51% at September 30, 2005, compared to
0.64% at September 30, 2004. As a percent of total loans, the allowance for loan
losses was 1.21% at September 30, 2005, compared to 1.16% at September 30, 2004.
As a percent of nonperforming loans, the allowance for loan losses was 946.72%,
compared to 160.74% at September 30, 2004.

         Pinnacle Bancshares, Inc.'s wholly owned subsidiary Pinnacle Bank has
six offices located in central and northwest Alabama.
