IBT Bancorp, Inc.
         Announces Operating Results for the Quarter ended June 30, 2006

Irwin,  Pennsylvania,  July 17, 2006;  IBT Bancorp,  Inc. (the  "Company"),  the
holding  company of Irwin Bank & Trust Company,  today  announced the results of
its  operations for the three and six months ended June 30, 2006. Net income for
the three month  period ended June 30, 2006 was  $2,185,000  or $.73 per diluted
share compared to $2,326,000 or $.78 per diluted share for the  comparable  2005
quarter.  For the six month period ended June 30, 2006 net income was $4,496,000
or $1.51 per diluted share compared to $4,650,000 or $1.56 per diluted share for
the comparable 2005 six month period.

For the quarter ended June 30, 2006, net interest income decreased $55,000 or 1%
while  non-interest  income increased  $81,000 or 4.55% due to the gain realized
from the sale of securities. The provision for loan losses increased to $550,000
for the quarter  ended June 30, 2006  compared to $300,000 for the quarter ended
June 30, 2005 due to an  increase in  classified  loans.  Non-interest  expenses
increased  to  $4,218,000  for the  quarter  ended  June 30,  2006  compared  to
$4,064,000  for the  comparable  quarter  in 2005.  Pension  and other  employee
benefits  increased  $96,000  as a result  of  increases  in  pension  costs and
employee medical costs.  Other  non-interest  expenses also increased with other
expenses  increasing  $113,000 or 10.78%. For the six months ended June 30, 2006
net interest income decreased  $259,000.  Non-interest income increased $301,000
or 8.84% due mainly to the increases in security  gains.  Non-interest  expenses
increased  $481,000  due to an increase  of  $202,000  in pension  and  employee
benefit costs due to increased  pension costs and increases in employee  medical
cost. Other expenses  increased  $164,000 as a result of normal increases in the
cost of doing business.

President and CEO Charles G. Urtin stated, "Continued interest rate increases by
the Federal  Reserve  have  resulted in a flattening  of the yield  curve.  This
flattening,  and increased  competition  for deposits have increased the cost of
our interest bearing  liabilities.  However,  interest rates on interest earning
assets have not risen as quickly or by the same  amounts.  We have been changing
the  composition of our loan portfolio to add more  asset-secured  loans,  which
earn higher rates of interest than real estate secured loans.  While this change
in composition has resulted in an increase in the provision for loan losses, and
current  competition  for deposits and the flatter  yield curve have  negatively
impacted  profitability,  we believe that our strategy for the long-term  should
produce positive results."

Total  assets of the Company were  $717,006,000  at June 30, 2006 as compared to
$685,151,000  at December 31, 2005. Net loans  increased to $459,119,000 at June
30, 2006 from  $442,225,000  at December  31,  2005.  Investments  increased  to
$206,004,000  at June 30, 2006 as compared to $195,993,000 at December 31, 2005.
Total deposits were $535,249,000 at June 30, 2006 as compared to $520,486,000 at
December 31, 2005.  Repurchase  agreements  were  $31,384,000  at June 30, 2006,
compared to  $18,443,000  at December 31, 2005.  Advances  from the Federal Home
Loan Bank of Pittsburgh increased to $78,576,000 at June 30, 2006 as compared to
$68,651,000  at December  31,  2005.  The Company  takes  advantage of favorable
interest  rates offered by the Federal



Home Loan Bank of Pittsburgh and uses the proceeds to make investments and loans
at rates  higher than those  charged  for the  borrowings.  Total  stockholders'
equity  declined to  $59,696,000  at June 30, 2006  compared to  $61,081,000  at
December 31, 2005 due primarily to the change in accumulated other comprehensive
income. This change is attributable to the negative impact rising interest rates
have on the investment portfolio.

During the quarter the Company repurchased 12,160 shares on the open market at a
weighted average cost of $40.38 per share.
