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

Irwin,  Pennsylvania,  October 16, 2006;  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, 2006.  Net income
for the  three-month  period ended September 30, 2006 was $2,151,000 or $.72 per
diluted  share  compared  to  $2,038,000  or  $.68  per  diluted  share  for the
comparable 2005 quarter. For the nine-month period ended September 30, 2006, net
income was $6,647,000 or $2.24 per diluted share compared to $6,688,000 or $2.24
per diluted share for the comparable period in 2005.

The  increase  in net income for the  quarter  reflects  increased  non-interest
income which offset higher non-interest  expenses and an increased provision for
loan losses.  Non-interest  income increased $301,000 or 18% from the comparable
2005  quarter.  The  increase  in  non-interest  income is due  primarily  to an
increase in net investment security gains of $239,000 and an increase in service
fees of $55,000 or 6% compared to the  comparable  2005  quarter.  Net  interest
income  after the  provision  for loan loss  decreased  $45,000  or 1% due to an
increase in the provision for loan losses of $50,000. Net interest income before
the provision for loan losses  actually  increased  $5,000 or less than .1% over
the comparable  quarter in 2005.  Non-interest  expenses increased to $4,275,000
for the  quarter  ended  September  30,  2006  compared  to  $4,135,000  for the
comparable 2005 quarter.  Pension and other employee benefits increased $189,000
or 42%  compared  to the 2005  quarter  due to an increase in pension and health
care costs.

For the nine months ended  September  30, 2006,  net interest  income  decreased
$254,000 and the provision for loan losses  increased  $300,000  causing the net
interest  income  after the  provision  for loan losses to decrease  $554,000 or
3.5%.  Non-interest income increased $602,000 or 12% over the comparable quarter
in 2005 due  primarily to an increase in net  security  gains of $640,000 and an
increase in service fees of $109,000.  Other  income  decreased  $201,000 due to
sales  of real  estate  sold at a gain in 2005  which  did not  occur  in  2006.
Non-interest  expenses  increased $622,000 due primarily to



increases in pension and employee  health care costs of $391,000 or 29% compared
to the nine-month period ended September 30, 2005.

President and CEO Charles G. Urtin  stated,  "The increase in net income for the
quarter ended September 30, 2006 is due primarily to increase in security gains.
Net interest income has remained flat, which,  during this period of an inverted
yield  curve  is  a  positive  development.  We  have  also  seen  increases  in
non-interest  income,  excluding  securities  gains,  and  increases in employee
benefit  costs.  For the year to date  there  was no  material  change  from the
previous nine-month period. Increases in non-interest income have been offset by
comparable increases in non-interest expenses."

Total net loans  reached  $464,400,000  at  September  30,  2006 as  compared to
$442,225,000  at December 31, 2005.  Investments  increased to  $206,479,000  at
September  30, 2006 as compared to  $195,993,000  at December  31,  2005.  Total
deposits were  $548,719,000 at September 30, 2006 as compared to $520,486,000 at
year-end.  Advances from the Federal Home Loan Bank of  Pittsburgh  increased to
$69,909,000  at September  30, 2006 as compared to  $68,651,000  at December 31,
2005. Repurchase agreements nearly doubled to $38,929,000.
