                                IBT Bancorp, Inc.
     Announces Operating Results for the First Quarter Ended March 31, 2003

Irwin,  Pennsylvania,  April 25, 2003: IBT Bancorp,  Inc., (the "Company"),  the
holding  company of Irwin Bank & Trust Company,  today  announced its results of
operations  for the three months ended March 31, 2003.  The Company's net income
for the three months ended March 31, 2003 increased $198,000 to $2,629,000, or $
..88 per  diluted  earnings  per share,  from  $2,431,000,  or $ .81 per  diluted
earnings per share, for the comparable 2002 quarter.

President  and CEO  Charles  G. Urtin  stated,  "We have been able to manage our
balance  sheet to produce an increase in net income over the prior  year's first
quarter despite continued pressure on the net interest margin resulting from the
current  historically  low  interest  rates  earned  on  the  Company's  assets.
Increases in loan volume, however, have contributed to the improved results."

Total assets of the Company  increased  $15,529,000 to $599,564,000 at March 31,
2003 as compared to  $584,035,000  at December  31,  2002.  Total loans  reached
$372,466,000  at March 31, 2003 from  $359,872,000  at  December  31,  2002,  an
increase of $12,594,000 or 3.5%.  Investments increased to $188,054,000 at March
31, 2003 as compared to $186,718,000  at December 31, 2002.  Total deposits were
$468,132,000  at March 31, 2003 as compared to total deposits of $468,257,000 at
December 31, 2002.  The decrease in total deposits of $125,000 was primarily the
result of expected reductions in deposits of local  municipalities.  The Company
also took  advantage  of low-rate  advances  from the Federal  Home Loan Bank of
Pittsburgh.  Outstanding advances at March 31, 2003 were $53,875,000 compared to
$40,000,000 at December 31, 2002.
