IBT Bancorp, Inc.
        Announces Operating Results for the Quarter Ended March 31, 2006

Irwin, Pennsylvania, May 2, 2006; IBT Bancorp, Inc. (the "Company"), the holding
company of Irwin Bank and Trust Company,  today announced earnings of $2,310,000
or $.78 per  diluted  share for the quarter  ended  March 31,  2006  compared to
$2,324,000 or $.78 per diluted share for the comparable 2005 quarter.

For the three  months  ended  March 31,  2006 net  interest  income  before  the
provision for loan losses  decreased to $5,407,000  from  $5,611,000  during the
comparable 2005 period.  While interest income  increased 8% over the comparable
2005  quarter,  interest  expense  increased  28%. This is due to rates paid for
deposits  increasing  at a rate  faster  than rates  charged  for  loans.  Total
non-interest income increased to $1,845,000 for the quarter ended March 31, 2006
compared to $1,625,000 for the comparable  quarter in 2005 primarily as a result
of increases in gains on securities sales.  Total  non-interest  expense for the
quarter  ended March 31, 2006 was  $4,038,000  compared  to  $3,710,000  for the
comparable  quarter in 2005.  The  increase is due  primarily  to  increases  in
salaries and benefits due to expanded staff and normal salary increases.  Income
taxes  decreased to $604,000 for the quarter  ended March 31, 2006 from $902,000
for the  comparable  quarter in 2005 as a result of an increase  in  non-taxable
security gains on the sale of preferred stocks written down in December 2004.

President  and CEO Charles G. Urtin stated,  "Increases  in short-term  interest
rates by the Federal Reserve have caused  increased upward pressure on the rates
we pay for deposits.  These rates are increasing faster than the rates we charge
for loans. As loan rates on new and adjustable loans increase to new levels,  we
expect less narrowing of the net interest margin."

Total assets of the Company were  $706,357,000  at March 31, 2006 as compared to
$685,151,000  at December 31, 2005. Net loans increased to $450,966,000 at March
31, 2006 from  $442,225,000  at December  31,  2005.  Investments  increased  to
$200,232,000 at March 31, 2006 as compared to $195,993,000 at December 31, 2005.
Total deposits were  $526,704,000  at March 31, 2006 as compared to $520,486,000
at December 31,  2005.  Advances  from the Federal Home Loan Bank of  Pittsburgh
increased  to  $78,990,000  at March 31,  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.

During the quarter the Company  repurchased 1,375 shares on the open market at a
weighted average cost of $38.08 per share.
