JANUARY 20, 2006
                            AMES NATIONAL CORPORATION
                                    ANNOUNCES
                        2005 AND FOURTH QUARTER EARNINGS


As of December 31, 2005,  loan levels  reached  record highs with total  assets,
deposits  and capital  reaching  record highs in the first two quarters of 2005.
However,  the record  balance  sheet  figures did not  translate  into  improved
profitability  for the Company in 2005.  Net income for the year ended  December
31, 2005  decreased 6% to  $11,609,000  or $1.23 per share  compared to the 2004
results of $12,390,000 or $1.32 per share.

Rising market interest rates resulted in annual net interest income declining 5%
as deposits  repriced  more  quickly  than loans and  investments.  Net interest
income of  $25,373,000  was  recorded  for the year ending  December 31, 2005 in
comparison  to the  $26,790,000  recorded  in 2004.  The  Company's  annual  net
interest margin declined to 3.56% in 2005 compared to the 3.97% posted in 2004.

Annual interest expense on interest bearing  liabilities rose to $15,933,000 for
2005  compared  to  $10,563,000  posted  for 2004,  a 51%  increase.  The higher
interest  expense  was  offset  by an 11%  increase  in annual  interest  income
totaling $41,306,000 for 2005 compared to the $37,354,000 recorded for 2004.

Return on average  assets  for 2005 and 2004 was 1.40% and 1.56%,  respectively.
Return on equity for the same periods  equaled 10.57% and 11.47%,  respectively.
The efficiency  ratio for the year ending  December 31, 2005 was 49.09% compared
to 46.59% for the previous year. The decline in the efficiency ratio in 2005 was
primarily the result of lower net interest income as the 2005 annual noninterest
expense  increased less than 2% compared to the same period in 2004.  Annual net
securities gains,  primarily  relating to the Company's equity  securities,  and
higher trust  department  revenues  contributed  to a 7% increase in noninterest
income in 2005 compared to year end 2004 totals.

Net income for the quarter  ended  December 31, 2005 was  $2,709,000,  15% lower
than the $3,191,000  earned in the fourth quarter last year.  Earnings per share
were $0.29 for the  quarter  compared to over $0.34 for the same period in 2004.
Quarterly  earnings are lower as higher market interest rates have also resulted
in lower quarterly net interest income.  Net interest income has declined 13% to
$6,053,000 for the fourth quarter ended December 31, 2005 compared to $6,948,000
for the  same  quarter  one year  ago.  Fourth  quarter  2005  interest  expense
increased 49% while interest  income rose only 6% compared to the fourth quarter
of 2004 as loan and investment repricing has lagged behind the liability side of
the balance sheet.

Fourth  quarter  2005  return on average  assets was 1.32%  compared to 1.53% in
fourth  quarter  2004.  Return on average  equity was 9.94% for the three months
ended December 31, 2005 compared to the 11.56% posted a year ago. The efficiency
ratio for fourth quarter was 50.67%, compared to 46.41% last year.

Deposits  increased to $668,342,000 on December 31, 2005, a 2% increase over the
$658,176,000  recorded at year-end 2004. An increase in certificates of deposits
offset  significantly  lower  interest  bearing  checking (NOW) and money market
account deposit  balances.  The reduction in interest  checking and money market
accounts is partially the result of depositors  moving money to higher  yielding
certificates of deposit. United Bank & Trust,  Marshalltown,  State Bank & Trust
Co., Nevada, and First National Bank, Ames increased their deposits in 2005.

Loans rose 9.0% to $440,318,000,  a $28,679,000 increase over year end 2004 with
commercial operating and commercial real estate loans accounting for most of the
growth. The allowance for loan losses as of December 31, 2005 totaled $6,765,000
compared to $6,476,000 on December 31, 2004. Net  charge-offs for the year ended
December 31, 2005 were $41,000 compared to $55,000 for the previous year.

Year end  capital  declined  2% to  $109,227,000  compared  to  $110,924,000  on
December  31,  2004.  Included in capital  are  unrealized  gains on  securities
available for sale, which amounted to $3,292,000 compared to $7,468,000 in 2004.
Capital represented over 13% of total assets at the end of 2005 and 2004.

Company stock,  which is listed on the NASDAQ  SmallCap  Market under the symbol
ATLO,  closed at $25.71 on December 31,  2005.  During the fourth  quarter,  the
price ranged from $23.12 to $29.00.  The 2005  dividends paid of $0.91 per share
were 15% higher than the $0.80 per share paid in 2004.

Ames National  Corporation  affiliate Iowa banks are First National Bank,  Ames;
Boone Bank & Trust Co.,  Boone;  State Bank & Trust Co.,  Nevada;  Randall-Story
State Bank, Story City; and United Bank & Trust, Marshalltown.
