                            AMES NATIONAL CORPORATION
                                    ANNOUNCES
                             THIRD QUARTER EARNINGS



Ames  National  Corporation  is  headquartered  in Ames,  Iowa with  five  banks
including  twelve  banking  offices in central Iowa.  Affiliate  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.

Net income for the quarter ended  September 30, 2004 was  $3,372,000,  4% higher
than the  $3,241,000  earned in the third quarter last year.  Earnings per share
were $1.08 for the quarter  slightly  higher  than the $1.03  earned in the same
period in 2003.  Return on average  assets was 1.70%  compared to 1.78% in third
quarter  2003.  Return on average  equity was 12.66% for the three  months ended
September 30, 2004 which  compares to 12.42%  posted a year ago. The  efficiency
ratio for third  quarter was 45.85%  compared to 44.02% for the same period last
year.  Net interest  margin for the third quarter 2004 was 3.95%,  slightly less
than the 4.10% for third quarter 2003. Net loan  recoveries  totaled $99,000 for
the three months ended  September 30, 2004 compared to net loan  charge-offs  of
$19,000 for the three months ended  September 30, 2003. A loan recovery at First
National Bank of $136,000 relating to a problem  commercial credit resulted in a
negative provision for loan losses for the third quarter.

The Company  recorded  higher earnings for third quarter 2004 despite much lower
gains from securities  transactions and secondary market loan fees. Contributing
to this quarter's  earnings was higher net interest income and the fact that non
interest expense was only slightly higher than third quarter 2003.

For the nine month period  ending  September  30, 2004,  the Company  earned net
income of  $9,199,000,  or $2.94 per  share,  a 5%  increase  over net income of
$8,760,000,  or $2.80 per share, earned a year ago. A stable net interest margin
and a higher volume of earning  assets  resulted in an additional  $1,315,000 in
net  interest  income for the first  nine  months of 2004  compared  to the same
period a year ago. For the first nine months of 2004,  the improved net interest
income was offset by lower security gains and lower  secondary  market  mortgage
loan fees.  Net interest  margin for the first three quarters was 4.00% compared
to 4.02% for the same period in 2003. Net loan  recoveries  totaled  $56,000 for
the nine months ended  September  30, 2004 compared to net loan  charge-offs  of
$321,000 for the nine months ended September 30, 2003.

Total assets  reached a record $800 million,  $62 million  higher than the third
quarter of 2003 with significant growth in both loans and investments.

Deposits  increased to $648,917,000  for third quarter 2004, an 8% increase over
the  $602,522,000  recorded in third quarter 2003 with interest bearing checking
account deposits accounting for most of the increase.

Loans  rose 12% to a record  $387,743,000,  a $42  million  increase  over third
quarter 2003 with commercial real estate accounting for most of the gain.

Third quarter 2004 capital rose 5% to  $109,644,000  compared to $104,836,000 on
September  30,  2003.  Included  in  capital  are  unrealized  capital  gains on
securities  available  for  sale  in  the  amount  of  $7,842,000,  compared  to
$7,850,000 posted at the end of third quarter 2003. Capital represented 13.7% of
total assets at the end of third quarter 2004.

Company  stock,  which is listed on the  Bulletin  Board under the symbol  ATLO,
closed at $71.00 on September  30, 2004.  During third  quarter the price ranged
from  $62.25 to  $71.50.  The  third  quarter  dividend  paid was $.49 per share
compared to $.46 per share paid in the same  quarter a year ago. The Company has
recently  submitted  an  application  to have it common  stock  listed on NASDAQ
SmallCap  Market.  In order to comply with the listing  requirements for NASDAQ,
the  Company  has amended  its Audit  Committee  Charter  which can be viewed at
