    Glacier Bancorp, Inc. (Nasdaq: GBCI) reported net quarterly earnings of
$13.629 million, an increase of $2.1 million, or 18 percent, over the $11.520
million for the first quarter of 2005. Diluted earnings per share for the
quarter of $.42 is an increase of 14 percent over the per share earnings of $.37
for the same quarter of 2005. Net earnings were reduced by $523,488, or $.016
per share, due to the January 1, 2006 adoption of SFAS 123(R) Share- based
Payment which requires recording the estimated fair value of stock options as
compensation expense. "2006 is starting off to be another good year for Glacier
Bancorp, Inc. Loan growth in the first quarter was very strong," said Mick
Blodnick, President and Chief Executive Officer. "As a result of this growth our
net interest margin continued to expand." Annualized return on average assets
and return on average equity for the quarter were 1.48 percent and 16.21
percent, respectively, which compares with prior year returns for the first
quarter of 1.50 percent and 17.06 percent. Annualized return on average tangible
equity, a non-GAAP performance measure, for the first quarter of 2006 was 22.48
percent compared to 20.99 percent in the first quarter of last year.

</TABLE>

    At March 31, 2006 total assets were $3.800 billion, which is $94 million, or
3 percent, greater than the December 31, 2005 assets of $3.706 billion, and $494
million, or 15 percent, greater than the March 31, 2005 assets of $3.306
billion.

    Total loans have increased $131 million from December 31, 2005, or 5
percent, with the growth occurring in all loan categories. Commercial loans have
increased $79 million, or 6 percent, real estate loans gained $31 million, or 5
percent, and consumer loans grew by $22 million, or 5 percent. "The first
quarter loan production again benefited from a very mild winter," Blodnick said.
"In addition our markets continue to experience good activity and growth." Total
loans have increased $658 million, or 34 percent, from March 31, 2005, with all
loan categories showing increases. Commercial loans grew the most with an
increase of $348 million, or 32 percent, followed by real estate loans which
increased $205 million, or 47 percent, which was the largest percentage gain,
and consumer loans, which are primarily comprised of home equity loans,
increasing by $105 million, or 27 percent.

    Investment securities, including interest bearing deposits in other
financial institutions, and federal funds sold have decreased $37 million from
December 31, 2005, or 4 percent, and have declined $217 million, or 19 percent,
from March 31, 2005. Investment securities at March 31, 2006 represented 25% of
total assets versus 35% the prior year. "Cash flow from the investment portfolio
continues to fund the significant loan growth," said Jim Strosahl, Chief
Financial Officer. "Converting the lower yielding investments into loans has
contributed to the interest margin growth."

    Non-interest bearing deposits have increased $16 million, or 10 percent
annualized, since December 31, 2005, and by $155 million, or 29 percent, since
March 31, 2005. This continues to be a primary focus of each of our banks.
Interest bearing deposits have increased $142 million from December 31, 2005, of
which $71 million was in broker originated certificates of deposit, and $53
million in Internet generated National Market CD's. Since March 31, 2005
interest bearing deposits increased $562 million, or 39 percent, with $289
million of that amount from broker and Internet sources. Federal Home Loan Bank
(FHLB) advances increased $103 million, and repurchase agreements and other
borrowed funds decreased $182 million from December 31, 2005, primarily from the
redemption of $179 million in U. S. Treasury Tax and Loan Term Auction funds.
FHLB advances are $354 million less than the March 31, 2005 balances due
primarily to the above described increases in deposits.

    Total equity and book value per share amounts have increased $11.152 million
and $.30 per share, respectively, from December 31, 2005, the result of earnings
retention, and stock options exercised. Accumulated other comprehensive income,
representing net unrealized gains on securities available for sale, decreased
$689 thousand during the quarter, primarily a function of interest rate changes
and the decreased balance of securities.

    Net Interest Income

    Net interest income for the quarter increased $7.852 million, or 28 percent,
over the same period in 2005, and $604 thousand from the fourth quarter of 2005.
Total interest income increased $15.445 million from the prior year's quarter,
or 38 percent, while total interest expense was $7.593 million, or 63 percent
higher. The increase in interest expense is primarily attributable to the volume
increase in interest bearing liabilities, and increases in short term interest
rates during 2005 continuing into 2006. The Federal Reserve Bank has increased
the targeted fed funds rate 10 times, 250 basis points, since January 1, 2005.
The net interest margin as a percentage of earning assets, on a tax equivalent
basis, was 4.32 percent which was higher than the 4.08 percent result for the
first quarter of 2005. The margin for the first quarter of 2006 continued the
trend of increases experienced in each quarter of 2005.

<PAGE>

    Non-interest Income

    Fee income increased $1.735 million, or 27 percent, over the same period
last year, driven primarily by an increased number of loan and deposit accounts
from internal growth and acquisitions. Gain on sale of loans increased $98
thousand, or 5 percent, from the first quarter of last year. Loan origination
activity for housing construction and purchases remains strong in our markets.

    Non-interest Expense

    Non-interest expense increased by $6.753 million, or 35 percent, from the
same quarter of 2005. Compensation and benefit expense increased $4.367 million,
or 40 percent, of which $723 thousand was from expensing stock options with the
adoption of SFAS 123(R) in 2006, four acquisitions during 2005, the addition of
four new bank branches occurring within the last four months, normal
compensation increases for job performance and increased cost for benefits are
the reasons for the majority of the increase. The number of full-time-equivalent
employees has increased from 952 to 1,147, a 20 percent increase, since March
31, 2005. Occupancy and equipment expense increased $636 thousand, or 22
percent, reflecting the bank acquisitions, cost of additional branch locations
and facility upgrades. Other expenses increased $1.121 million, or 24 percent,
primarily from acquisitions, additional marketing expenses, and costs associated
with new branch offices. "The number of new branches coming on-line within a
short period of time has resulted in significantly higher expenses in the
current quarter," said Strosahl. "Although the number of new locations is
greater than normal for our company, rapid expansion in the high growth markets
of Boise and Coeur d'Alene will have long-term benefits." The efficiency ratio
(non-interest expense/net interest income + non-interest income) was 54 percent
for the 2006 quarter, up from 51 percent for the 2005 quarter.

    Allowance for Loan Loss and Non-Performing Assets

    Non-performing assets as a percentage of total assets at March 31, 2006 were
at .27 percent, the same percentage as at March 31, 2005, but increasing
slightly from .26 percent at December 31, 2005. The Company ratios compare
favorably to the Federal Reserve Bank Peer Group average of .43 percent at
December 31, 2005, the most recent information available. The allowance for loan
losses was 386 percent of non-performing assets at March 31, 2006, up from 325
percent a year ago. The allowance, including $4.579 million from acquisitions,
has increased $10.050 million, or 34 percent, from a year ago. The allowance of
$39.851 million, is 1.55 percent of March 31, 2006 total loans outstanding, down
slightly from the 1.56 percent a year ago. The first quarter provision for loan
losses expense was $1.165 million, a decrease of $325 thousand from the same
quarter in 2005, and was also a decrease of $209 thousand from the fourth
quarter of 2005. Recovery of previously charged-off loans exceeded amounts
charged-off during the quarter by $31,000. Loan growth, average loan size, and
credit quality considerations will determine the level of additional provision
expense.

    Cash dividend

    On March 29, 2006, the board of directors declared a cash dividend of $.16
payable April 20, 2006 to shareholders of record on April 11, 2006, which is an
increase of 14 percent over the $.14 dividend declared in the first quarter of
last year.
