                                IBT Bancorp, Inc.
                       Announces Operating Results for the
                Fourth Quarter and Year Ended December 31, 2006

Irwin,  Pennsylvania,  February 6, 2007:  IBT Bancorp,  Inc.,  (the  "Company"),
(AMEX:  IRW) the holding company of Irwin Bank & Trust Company,  today announced
its results of operations for the three months and year ended December 31, 2006.
The Company's net income for the three months ended  December 31, 2006 decreased
$82,000 to $1,809,000 or $ .30 per diluted earnings per share, from $1,891,000,
or $ .32 per diluted  earnings  per share,  (adjusted  for the effects of a 100%
stock dividend paid on November 16, 2006) for the comparable  2005 quarter.  Net
income for the year ended December 31, 2006 decreased $123,000 to $8,456,000, or
$ 1.42 per diluted  earnings  per share,  from  $8,579,000  or $1.44 per diluted
earnings  per share,  (adjusted  for the effects of a 100% stock  dividend  paid
November 16, 2006) for the comparable 2005 period.

President  and CEO,  Charles G.  Urtin,  stated  "The  inverted  yield curve and
significant  increases in health care costs  contributed  to the decrease in net
income for the quarter and for the year.  The inverted  yield curve,  which pays
higher   interest  rates  for  short-term   instruments   than  for  longer-term
instruments, has made it difficult to lend profitably and has eaten into our net
interest income.  Employee benefit costs increased to $2.5 million for 2006 from
$1.8 million for 2005 due to rapidly increasing health care costs. Despite these
near-term challenges,  we continue to manage the Company for the long-term. I am
pleased to report that we have  continued to grow the Company and maintained the
dividend."

Total assets of the Company  increased  $55,811,000 to  $740,962,000 at December
31, 2006 as compared to $685,151,000  at December 31, 2005.  Total loans reached
$467,721,000  at December 31, 2006 from  $442,225,000  at December 31, 2005,  an
increase  of  $25,495,000  or  5.8%.   Investments   increased   $25,256,000  to
$221,249,000  at December 31, 2006 as compared to  $195,993,000  at December 31,
2005, an increase of 12.9%. Total deposits reached  $572,472,000 at December 31,
2006 as compared to total  deposits of  $520,486,000  at December 31, 2005.  The
increase in deposits was primarily the result of the growth in  certificates  of
deposit, which increased  $57,820,000,  or 23.0% over the prior year. Securities
sold to  repurchase,  which secure our sweep  accounts,  grew to  $27,417,000 at
December  31,  2006,  an  increase  of  $8,974,000  or 49%  compared to



balances  outstanding at December 31, 2005.  Outstanding advances at the Federal
Home Loan Bank of Pittsburgh at December 31, 2006 were  $72,410,000  compared to
$68,651,000 at December 31, 2005.
