                                IBT Bancorp, Inc.
                Announces Operating Results for the Third Quarter

Irwin,  Pennsylvania,  October 27, 2004;  IBT Bancorp,  Inc.  (AMEX:  IRW),  the
holding  company of Irwin Bank & Trust Company,  today  announced its results of
operations  for the three and nine months ended  September 30, 2004.  Net income
for the  three-month  period ended September 30, 2004 was $2,161,000 or $.72 per
diluted  share  compared  to  $2,562,000  or  $.85  per  diluted  share  for the
comparable 2003 quarter. For the nine-month period ended September 30, 2004, net
income was $6,602,000 or $2.20 per diluted share compared to $7,647,000 or $2.57
per diluted  share for the  comparable  period in 2003.  For the  quarter  ended
September  30,  2004,  net  interest  income  declined  $214,000  or 3.78% while
non-interest  income declined  $312,000 or 20% from the comparable 2003 quarter.
The decline in net interest income was caused by a continuing compression of the
net  interest  margin,  which  narrowed  to 3.46% for the third  quarter of 2004
compared to 3.89% for the comparable 2003 quarter. Non-interest income decreased
on a  quarter-to-quarter  basis due to lower gains on  security  and loan sales.
Non-interest  expenses  increased to $3,715,000 for the quarter ended  September
30, 2004  compared to  $3,582,000  for the  comparable  2003  quarter.  Although
salaries declined $15,000,  employee benefits and occupancy expenses  increased,
which accounted for the overall increases in non-interest expenses. For the nine
months ended September 30, 2004, net interest  income  declined  $294,000 due to
the decrease in the net interest margin.  Non-interest  income declined $754,000
due to the one-time  gain on the sale of real estate  owned,  which  occurred in
April of 2003,  and a decrease  in gains on the sale of  investment  securities.
Non-interest  expenses increased $660,000 due to increases in employee benefits,
the  opening  of the  new  Greensburg  branches  and  continued  investments  in
technology.

President  and CEO Charles G. Urtin  stated,  "The  pressure on our net interest
margin,  which  impacted  net  income in the first two  quarters  of this  year,
continues.  The net interest margin for the  three-month  period ended September
30, 2004 declined 43 basis points to 3.46%  compared to the same period in 2003.
For the nine months ended  September 30, 2004, net interest  margin  declined 33
basis points to 3.55%  compared to the  nine-month  period ended  September  30,
2003.  The fed funds rate has  increased  to 1.75% and this will have a positive
impact on the yield on our short-term investments.  However, the uptick in rates
and increased competition for deposits could increase our cost of deposits.  The
Company  continues to grow and to pay a dividend.  Total assets at September 30,
2004 increased $47,396,000 or 7.5% to $676,926,000 from $629,530,000 at December
31, 2003. We continue to manage the Company with long term goals in mind."

Total net loans  reached  $432,475,000  at  September  30,  2004 as  compared to
$416,286,000  at December 31, 2003.  Investments  increased to  $204,781,000  at
September  30, 2004 as compared to  $172,448,000  at December  31,  2003.  Total
deposits





were  $512,690,000 at September 30, 2004 as compared to $492,157,000 at
year end.  Advances from the Federal Home Loan Bank of  Pittsburgh  increased to
$70,662,000  at September  30, 2004 as compared to  $53,308,000  at December 31,
2003.  Repurchase  agreements  nearly  doubled  to  $24,682,342.  Federal  funds
purchased at September  30, 2004 were  $4,912,000  as compared to  $7,900,000 at
December 31, 2003.

The Company  repurchased  5,100  shares  during the quarter as  authorized  by a
previously  approved  stock buy-back  plan,  which  authorized the repurchase of
151,100 shares. As of this date, 68,344 shares have been repurchased with 82,756
shares remaining. Shares will be used for general corporate purposes and will be
purchased from time to time as conditions dictate.
