                          IBT Bancorp, Inc. (AMEX: IRW)
                       Announces Operating Results for the
                 Fourth Quarter and Year Ended December 31, 2004

Irwin,  Pennsylvania,  February 17, 2005:  [AMEX:  IRW] IBT Bancorp,  Inc., (the
"Company"),  the holding company of Irwin Bank & Trust Company,  today announced
its results of operations for the three months and year ended December 31, 2004.
The Company's net income for the three months ended  December 31, 2004 decreased
$2,516,000  to a loss of  $517,000,  or $ (.17) per diluted  earnings per share,
from  $1,999,000,  or $ .67 per diluted  earnings per share,  for the comparable
2003  quarter.  Net  income  for the year  ended  December  31,  2004  decreased
$3,561,000,  to  $6,085,000,  or $2.02 per  diluted  earnings  per  share,  from
$9,646,000,  or $3.19 per diluted  earnings per share,  for the comparable  2003
period. The Company previously announced an after tax charge to earnings related
to an other  than  temporary  impairment  in value of  certain  adjustable  rate
preferred stocks.  Excluding this charge,  net income for the quarter would have
been $1,864,000 or $.63 per fully diluted share. For the year ended December 31,
2004 net income would have been $8,466,000 or $2.82 per fully diluted share.

President  and CEO,  Charles  G.  Urtin,  stated,  "2004  saw an  interest  rate
environment unlike any seen in the last 50 years.  Interest rates were at record
lows.  While  rates  paid on  deposits  stabilized,  rates  earned  on loans and
investments continued to drop, negatively impacting our net interest margin, the
primary income generator of our Company.  A repeat  performance of 2003's record
net income would have been  difficult to meet.  Nevertheless,  we are pleased to
report  growth  in  assets,  deposits  and loans  while  continuing  to  control
non-interest expenses. We recently announced the consolidation of three offices.
These offices duplicated services in a 1.5 mile corridor. The consolidation into
a single location will represent a significant cost savings with little customer
impact.  Other  accomplishments  in 2004 included opening a second branch in the
city of Greensburg.  This location, near the Westmoreland County courthouse will
provide convenience to the professional community. Our Maximum Checking product,
announced late in 2003 has garnered over $19 million in deposits.  Last November
we introduced Overdraft  Advantage,  providing customers with the assurance that
overdrafts would be paid, subject to strict guidelines. We remain committed to a
consistent management approach focused on long-term performance and a commitment
to enhancing shareholder value."




Total assets of the Company  increased  $46,327,000 to  $675,857,000 at December
31, 2004 as compared to $629,530,000  at December 31, 2003.  Total loans reached
$436,548,000  at December 31, 2004 from  $416,286,000  at December 31, 2003,  an
increase of $20,262,000 or 5%. Investments increased $21,301,000 to $191,208,000
at December  31,  2004 as compared to  $169,907,000  at December  31,  2003,  an
increase  of 12%.  Favorable  rates on FHLB  advances  allowed  the  company  to
purchase investments at positive spreads. Total deposits reached $526,217,000 at
December 31, 2004 as compared to total deposits of  $492,158,000 at December 31,
2003.  The increase in deposits was  primarily the result of increases in demand
deposits and in  certificates of deposits.  As mentioned  previously the Company
also took advantage of favorably priced advances from the Federal Home Loan Bank
of  Pittsburgh.  Outstanding  advances  at December  31,  2004 were  $70,265,000
compared to $53,308,000 at December 31, 2003.
