the Glacier Bancorp, Inc.'s ("Company") operating results and financial
condition than can be obtained from reading the Consolidated Financial
Statements alone. The discussion should be read in conjunction with the
Consolidated Financial Statements and the notes thereto included in "Part I.
Item 1. Financial Statements."

                           FORWARD-LOOKING STATEMENTS

This Form 10-Q may contain forward-looking statements within the meaning of the
Private Securities Litigation Reform Act of 1995. These forward-looking
statements include, but are not limited to, statements about management's plans,
objectives, expectations and intentions that are not historical facts, and other
statements identified by words such as "expects," "anticipates," "intends,"
"plans," "believes," "should," "projects," "seeks," "estimates" or words of
similar meaning. These forward-looking statements are based on current beliefs
and expectations of management and are inherently subject to significant
business, economic and competitive uncertainties and contingencies, many of
which are beyond the Company's control. In addition, these forward-looking
statements are subject to assumptions with respect to future business strategies
and decisions that are subject to change. In addition to the factors set forth
in the sections titled "Risk Factors," "Business" and "Management's Discussion
and Analysis of Financial Condition and Results of Operations", as applicable,
in this report and the Company's 2020 Annual Report on Form 10-K, the following
factors, among others, could cause actual results to differ materially from the
anticipated results:
•the risks associated with lending and potential adverse changes of the credit
quality of loans in the Company's portfolio;
•changes in trade, monetary and fiscal policies and laws, including interest
rate policies of the Board of Governors of the Federal Reserve System or the
Federal Reserve Board, which could adversely affect the Company's net interest
income and profitability;
•changes in the cost and scope of insurance from the Federal Deposit Insurance
Corporation ("FDIC") and other third parties;
•legislative or regulatory changes, such as the those signaled by the Biden
Administration, as well as increased banking and consumer protection regulation
that adversely affect the Company's business, both generally and as a result of
the Company exceeding $10 billion in total consolidated assets;
•ability to complete pending or prospective future acquisitions;
•costs or difficulties related to the completion and integration of
acquisitions;
•the goodwill the Company has recorded in connection with acquisitions could
become impaired, which may have an adverse impact on earnings and capital;
•reduced demand for banking products and services;
•the reputation of banks and the financial services industry could deteriorate,
which could adversely affect the Company's ability to obtain and maintain
customers;
•competition among financial institutions in the Company's markets may increase
significantly;
•the risks presented by continued public stock market volatility, which could
adversely affect the market price of the Company's common stock and the ability
to raise additional capital or grow the Company through acquisitions;
•the projected business and profitability of an expansion or the opening of a
new branch could be lower than expected;
•consolidation in the financial services industry in the Company's markets
resulting in the creation of larger financial institutions who may have greater
resources could change the competitive landscape;
•dependence on the Chief Executive Officer ("CEO"), the senior management team
and the Presidents of Glacier Bank ("Bank") divisions;
•material failure, potential interruption or breach in security of the Company's
systems and technological changes which could expose us to new risks (e.g.,
cybersecurity), fraud or system failures;
•natural disasters, including fires, floods, earthquakes, and other unexpected
events;
•the Company's success in managing risks involved in the foregoing; and
•the effects of any reputational damage to the Company resulting from any of the
foregoing.

Forward-looking statements speak only as of the date of this Form 10-Q. The Company does not undertake any obligation to update or revise any forward-looking statements, whether as a result of new information, future events or otherwise, except as required by law.

The Company reported net income of $75.6 million for the current quarter, a
decrease of $2.2 million, or 3 percent, from the $77.8 million of net income for
the prior year third quarter. Diluted earnings per share for the current quarter
was $0.79 per share, a decrease of 2 percent from the prior year third quarter
diluted earnings per share of $0.81. The decrease in third quarter earnings over
the prior year was driven by a $21.6 million reduction in the gain on sale of
residential mortgage loans due to record gains in the prior year.

Acquisition


On October 1, 2021, the Company acquired the outstanding common stock of
Altabancorp, the parent company of Altabank, based in American Fork, Utah
(collectively, "Alta") and the largest community bank in Utah. Alta provides
banking services to individuals and businesses in Utah with twenty-five banking
offices from Preston, Idaho to St. George, Utah. As of September 30, 2021, Alta
had total assets of $3.648 billion, total loans of $1.901 billion and total
deposits of $3.279 billion. Upon closing of the transaction, Alta became the
Company's seventeenth Bank division.

Core deposits of $17.477 billion as of September 30, 2021 increased $742
million, or 18 percent annualized, from the prior quarter and increased $3.296
billion, or 23 percent, from the prior year third quarter. Non-interest bearing
deposits of $6.632 billion as of September 30, 2021 increased $325 million, or 5
percent, from the prior quarter and increased $1.153 billion, or 21 percent,
from the prior year third quarter. The unprecedented increase in deposits over
the prior eighteen months resulted from a number of factors including the PPP
loan proceeds deposited by customers, federal stimulus deposits and the increase
in customer savings. Non-interest bearing deposits were 38 percent of total core
deposits at September 30, 2021 compared to 37 percent of total core deposits at
December 31, 2020 and 39 percent at September 30, 2020.

The low levels of borrowings, including wholesale deposits and Federal Home Loan Bank ("FHLB") advances, reflected the significant increase in core deposits which funded the asset growth.

$36.1 million, or 2 percent, from the prior quarter and increased $143 million,
or 8 percent, from the prior year third quarter and was due to earnings
retention that more than offset the decrease in other comprehensive income. The
current year decrease in both the stockholders' equity to total assets ratio and
the tangible stockholders' equity to tangible assets was the result of the
$2.991 billion increase in debt securities driven primarily by the significant
influx of deposits during the current year. Tangible book value per common share
of $19.11 at the current quarter end increased $0.37 per share, or 2 percent,
from the prior quarter and increased $1.47 per share, or 8 percent, from a year
ago.

Cash Dividend
On September 30, 2021, the Company's Board of Directors declared a quarterly
cash dividend of $0.32 per share. The dividend was payable October 21, 2021 to
shareholders of record on October 12, 2021. The dividend was the 146th
consecutive dividend. Future cash dividends will depend on a variety of factors,
including net income, capital, asset quality, general economic conditions and
regulatory considerations.

Net Interest Income
The current quarter net interest income of $163 million increased $7.1 million,
or 5 percent, over the prior quarter and increased $11.2 million, or 7 percent,
from the prior year third quarter. The current quarter interest income of $167
million increased $6.8 million, or 4 percent, compared to the prior quarter and
increased $9.3 million, or 6 percent, over the prior year third quarter due to
an increase in interest income from the PPP loans and debt securities. The
interest income (which included deferred fees and deferred costs) from the PPP
loans was $12.9 million in the current quarter and $10.3 million in the prior
quarter and $9.3 million in the prior year third quarter. Excluding the PPP
loans, net interest income was $150 million in the current quarter compared to
$145 million in the prior quarter and $142 million in the prior year third
quarter.

The current quarter interest expense of $4.1 million decreased $359 thousand, or
8 percent, over the prior quarter and decreased $2.0 million, or 32 percent,
over the prior year third quarter primarily as result of a decrease in deposit
rates. During the current quarter, the total cost of funding (including
non-interest bearing deposits) of 9 basis points declined 1 basis points from
the prior quarter and declined 7 basis points from the prior year third quarter
with both decreases driven by a decrease in rates in deposits and borrowings.

The Company's net interest margin as a percentage of earning assets, on a
tax-equivalent basis, for the current quarter was 3.39 percent compared to 3.44
percent in the prior quarter and 3.92 in the prior year third quarter. The core
net interest margin, excluding 2 basis points of discount accretion, 2 basis
point from non-accrual interest and 18 basis points increase from the PPP loans,
was 3.17 percent compared to 3.33 in the prior quarter and 4.02 percent in the
prior year third quarter. The core net interest margin decreased 16 basis points
in the current quarter and decreased 85 basis points from the prior third
quarter due to a decrease in earning asset yields. Earning asset yields have
decreased due to the combined impact of the significant increase in the debt
securities and the lower yields on both core loans and debt securities. Debt
securities comprised 42.5 percent of the earning assets during the current
quarter compared to 39.4 percent in the prior quarter and 26.5 percent in the
prior year third quarter.

Non-interest Income
Non-interest income for the current quarter totaled $34.8 million which was a
decrease of $707 thousand, or 2 percent, over the prior quarter and a decrease
of $18.9 million, or 35 percent, over the same quarter last year. Service
charges and other fees increased $1.4 million from the prior quarter and
increased $1.8 million from the prior year third quarter as a result of

Gain on the sale of loans of $13.9 million for the current quarter decreased
$2.2 million, or 14 percent, compared to the prior quarter and decreased $21.6
million, or 61 percent, from the prior year third quarter. The current quarter
mortgage activity was lower than prior periods, but still remained at
historically strong levels.

Total non-interest expense of $104 million for the current quarter increased
$4.0 million, or 4 percent, over the prior quarter and increased $735 thousand,
or 71 basis points, over the prior year third quarter. Compensation and employee
benefits increased $2.3 million, or 4 percent, from the prior quarter and
increased $1.5 million from the prior year third quarter.

Other expenses of $15.3 million, increased $1.4 million, or 10 percent, from the
prior quarter and decreased $1.1 million, or 7 percent, from the prior year
third quarter. Current quarter other expenses included acquisition-related
expenses of $472 thousand compared to $1.1 million in the prior quarter and $793
thousand in the prior year third quarter.

Efficiency Ratio
The efficiency ratio was 50.17 percent in the current quarter and 49.92 percent
in the prior quarter and 48.05 in the prior year third quarter. Excluding the
impact from the PPP loans, the efficiency ratio would have been 53.59 percent in
the current quarter compared to 53.53 percent in the prior quarter. Excluding
the impact of PPP loans, the current quarter efficiency ratio was an increase of
308 basis points from the prior year third quarter efficiency ratio of 50.51
percent which was primarily driven by the decrease in the gain on sale of loans
in the current quarter.

The current quarter provision for credit loss expense for loans was $2.3 million
which was an increase of $8.0 million from the prior quarter provision for
credit loss benefit of $5.7 million and a $556 thousand decrease from the prior
year third quarter provision for credit loss expense of $2.9 million. The
increase in provision for credit losses for loans in the current quarter
compared to the prior quarter was primarily driven by organic loan growth in the
current quarter.

Net charge-offs for the current quarter were $152 thousand compared to net
recoveries of $725 thousand for the prior quarter and net charge-offs $826
thousand from the same quarter last year. Loan portfolio growth, composition,
average loan size, credit quality considerations, economic forecasts and other
environmental factors will continue to determine the level of the provision for
credit losses for loans.

The determination of the allowance for credit losses ("ACL" or "allowance") on
loans and the related provision for credit losses is a critical accounting
estimate that involves management's judgments about the loan portfolio that
impact credit losses. For additional information on the allowance, see the
Allowance For Credit Losses section under "Additional Management's Discussion
and Analysis."

Net Interest Income
Net-interest income of $475 million for the first nine months of 2021 increased
$40.9 million, or 9 percent, over the same period in 2020. Interest income of
$488 million for the first nine months of the current year increased $32.5
million, or 7 percent, from the prior year and was primarily attributable to a
$25.4 million increase in income from commercial loans, including $20.1 million
from the PPP loans. Additionally, interest income on debt securities increased
$14.2 million, or 20 percent, over the prior year which resulted from the
increased volume of debt securities. Interest expense of $13.4 million for the
first nine months of 2021 decreased $8.4 million, or 39 percent over the prior
year primarily as a result of a decrease in the cost of deposits. The total
funding cost (including non-interest bearing deposits) for the first nine months
of 2021 was 10 basis points, which decreased 12 basis points compared to 22
basis points in first nine months of 2020.

The net interest margin as a percentage of earning assets, on a tax-equivalent
basis, during the first nine months of 2021 was 3.52 percent, a 60 basis points
decrease from the net interest margin of 4.12 percent for the same period in the
prior year. The core net interest margin, excluding 3 basis points of discount
accretion, 1 basis point of non-accrual interest and 13 basis points increase
from the PPP loans, was 3.35 which was an 85 basis point decrease from the core
margin of 4.20 percent in the prior year. Although the Company was successful in
reducing the total cost of funding, it was not enough to outpace the lower
yields on core loans and debt securities driven by the current interest rate
environment and the shift in the earning asset mix to lower yielding debt
securities.

--------------------------------------------------------------------------------


Non-interest Income
Non-interest income of $110 million for the first nine months of 2021 decreased
$17.7 million, or 14 percent, over the same period last year. Service charges
and other fees of $41.7 million for the first nine months of 2021 increased $3.0
million, or 8 percent, from prior year as a result of additional fees from
increased customer accounts and transaction activity. Miscellaneous loan fees
and charges of $8.3 million increased $3.2 million, or 64 percent, driven by
increases in loan servicing income and credit card interchange fees due to
increased activity. Gain on the sale of loans of $51.6 million for the first
nine months of 2021 decreased $21.6 million, or 29 percent, compared to the same
period last year which was the result of the anticipated slowing of purchase and
refinance activity after the historically high levels in the prior year. Other
income of $8.7 million decreased $1.3 million from the prior year and was
primarily the result of a gain of $2.4 million on the sale of a former branch
building in the first quarter of 2020.

annual salary increases. Advertising and promotions for the first nine months of
2021 increased $1.1 million, or 15 percent, from the prior year. Regulatory
assessment and insurance for the first nine months of 2021 increased $2.0
million from the prior year same period primarily as a result of the State of
Montana waiving the first semi-annual regulatory assessment of 2020 and Small
Bank assessment credits applied by the FDIC in the first quarter of 2020. Other
expenses of $41.9 million, decreased $6.2 million, or 13 percent, from the prior

$7.3 million in the prior year.

Efficiency Ratio
The efficiency ratio was 48.94 percent for the first nine months of 2021

of 2021, including provision for credit loss benefit of $2.9 million on the loan
portfolio and credit loss benefit of $2.0 million on unfunded loan commitments.
The provision for credit loss benefit of $2.9 million on the loan portfolio in
the current year decreased $42.1 million over the provision for credit loss
expense of $39.2 million in the prior year which was primarily attributable to
changes in the economic forecast related to COVID-19. Net charge-offs during the
current year were $1.7 million compared to $2.9 million during the prior year.

The Company's debt securities are primarily comprised of state and local
government securities and mortgage-backed securities. State and local government
securities are largely exempt from federal income tax and the Company's federal
statutory income tax rate of 21 percent is used in calculating the
tax-equivalent yields on the tax-exempt securities. Mortgage-backed securities
largely consists of short, weighted-average life U.S. agency guaranteed
residential and commercial mortgage pass-through securities and to a lesser
extent, short, weighted-average life U.S. agency guaranteed residential
collateralized mortgage obligations. Combined, the mortgage-backed securities
provide the Company with ongoing liquidity as scheduled and pre-paid principal
is received on the securities.

State and local government securities carry different risks that are not as
prevalent in other security types. The Company evaluates the investment grade
quality of its securities in accordance with regulatory guidance. Investment
grade securities are those where the issuer has an adequate capacity to meet the
financial commitments under the security for the projected life of the
investment. An issuer has an adequate capacity to meet financial commitments if
the risk of default by the obligor is low and the full and timely payment of
principal and interest are expected. In assessing credit risk, the Company may
use credit ratings from Nationally Recognized Statistical Rating Organizations
("NRSRO" entities such as S&P and Moody's) as support for the evaluation;
however, they are not solely relied upon. There have been no significant
differences in the Company's internal evaluation of the creditworthiness of any
issuer when compared with the ratings assigned by the NRSROs.

The following table presents the carrying amount and weighted-average yield of
available-for-sale and held-to-maturity debt securities by contractual maturity
at September 30, 2021. Weighted-average yields are based upon the amortized cost
of securities and are calculated using the interest method which takes into
consideration premium amortization, discount accretion and mortgage-backed
securities' prepayment provisions. Weighted-average yields on tax-exempt debt
securities exclude the federal income tax benefit.

______________________________

1 Mortgage-backed securities, which have prepayment provisions, are not assigned to maturity categories due to fluctuations in their prepayment speeds.



Based on an analysis of its available-for-sale debt securities with unrealized
losses as of September 30, 2021, the Company determined their decline in value
was unrelated to credit loss and was primarily the result of interest rate
changes and market spreads subsequent to acquisition. The fair value of the debt
securities is expected to recover as payments are received and the debt
securities approach maturity. In addition, the Company determined an
insignificant amount of credit losses is expected on the held-to-maturity debt
securities portfolio; therefore, no ACL has been recognized at September 30,
2021.

For additional information on debt securities, see Note 2 to the Consolidated Financial Statements in "Part I. Item 1. Financial Statements."

Equity securities
Non-marketable equity securities primarily consist of capital stock issued by
the FHLB of Des Moines and are carried at cost less impairment. The Company also
has an insignificant amount of marketable equity securities that are included in
other assets on the Company's statements of financial condition.

Non-marketable equity securities and marketable equity securities without
readily determinable fair values are evaluated for impairment whenever events or
circumstances suggest the carrying value may not be recoverable. Based on the
Company's evaluation of its investments in non-marketable equity securities and
marketable equity securities without readily determinable fair values as of
September 30, 2021, the Company determined that none of such securities were
impaired.

Lending Activity
The Company focuses its lending activities primarily on the following types of
loans: 1) first-mortgage, conventional loans secured by residential properties,
particularly single-family; 2) commercial lending, including agriculture and
public entities; and 3) installment lending for consumer purposes (e.g., home
equity, automobile, etc.). Supplemental information regarding the Company's loan
portfolio and credit quality based on regulatory classification is provided in
the section captioned "Loans by Regulatory Classification" included in "Part I.
Item 2. Management's Discussion and Analysis of Financial Condition and Results
of Operations." The regulatory classification of loans is based primarily on the
type of collateral for the loans. Loan information included in "Part I. Item 2.
Management's Discussion and Analysis of Financial Condition and Results of
Operations" is based on the Company's loan segments, which are based on the
purpose of the loan, unless otherwise noted as a regulatory classification. The
following table summarizes the Company's loan portfolio as of the dates
indicated:

1Amounts represent estimated interest income that would have been recognized on
loans accounted for on a non-accrual basis as of the end of each period had such
loans performed pursuant to contractual terms.

Non-performing assets of $51.2 million at September 30, 2021 decreased $1.9
million, or 4 percent, over the prior quarter. Non-performing assets increased
$6.5 million, or 15 percent, over the prior year third quarter. Non-performing
assets as a percentage of subsidiary assets at September 30, 2021 was 0.24
percent compared to 0.26 percent in the prior quarter and 0.25 percent in the
prior year third quarter.

Early stage delinquencies (accruing loans 30-89 days past due) of $26.0 million
at September 30, 2021 increased $13.9 million from the prior quarter with a
large portion of the increase primarily isolated to one credit relationship.
Early stage delinquencies increased $8.4 million from the prior year third
quarter. Early stage delinquencies as a percentage of loans at September 30,
2021 was 0.23 percent, which was an increase of 12 basis points from prior
quarter and an 8 basis points increase from prior year third quarter.

Most of the Company's non-performing assets are secured by real estate, and
based on the most current information available to management, including updated
appraisals or evaluations (new or updated), the Company believes the value of
the underlying real estate collateral is adequate to minimize significant
charge-offs or losses to the Company. Through pro-active credit administration,
the Company works closely with its borrowers to seek favorable resolution to the
extent possible, thereby attempting to minimize net charge-offs or losses to the
Company. With very limited exceptions, the Company does not disburse additional
funds on non-performing loans. Instead, the Company proceeds to collection and
foreclosure actions in order to reduce the Company's exposure to loss on such
loans.

For additional information on accounting policies relating to non-performing
assets, see Note 1 to the Consolidated Financial Statements in "Part I. Item 1.
Financial Statements."

Restructured Loans
A restructured loan is considered a troubled debt restructuring ("TDR") if the
creditor, for economic or legal reasons related to the debtor's financial
difficulties, grants a concession to the debtor that it would not otherwise
consider. Each restructured debt is separately negotiated with the borrower and
includes terms and conditions that reflect the borrower's prospective ability to
service their obligations as modified. The Company discourages the use of the
multiple loan strategy when restructuring loans regardless of whether or not the
loans are designated as TDRs. The Company has TDR loans of $39.5 million and
$45.5 million at September 30, 2021 and December 31, 2020, respectively.

On March 27, 2020, the CARES Act was signed into law which includes many
provisions that impact the Company and its customers. The banking regulatory
agencies have encouraged banks to work with borrowers who have been impacted by
the COVID-19 pandemic, and the CARES Act, along with related regulatory
guidance, allows the Bank to not designate certain modifications as TDRs that
otherwise may have been classified as TDRs. For additional information on
modifications related to the COVID-19 pandemic, see the PPP section under
"Additional Management's Discussion and Analysis."

the loans into other real estate owned ("OREO") during 2021 was $1.6 million.
The fair value of the loan collateral acquired in foreclosure during 2021 was
$1.5 million. The following table sets forth the changes in OREO for the periods

The United States Small Business Administration ("SBA") Round 2 PPP program
ended in early May after the available funds were fully drawn upon. During the
first half of 2021, the Company originated $555 million of Round 2 PPP loans
which generated $33.2 million of SBA deferred processing fees and $6.7 million
of deferred compensation costs for total net deferred fees of $26.5 million.

During the current year, the SBA processing fees received on Round 2 averaged
5.99 percent which compared to the average of 3.75 percent received on Round 1
in the prior year. The increase in the fee percentage received on Round 2 was
the result of an increase in the number of smaller loans which receive a higher
percentage fee.

The Company received $327 million in PPP loan forgiveness during the current
quarter and received $1.103 billion in the first nine months of 2021. As of
September 30, 2021, the Company had $56 million, or 4 percent of the $1.472
billion of Round 1 PPP loans originated in the prior year and had $313 million,
or 56 percent of the $555 million of Round 2 PPP loans originated in the current
year.

The Company recognized $12.9 million of interest income (including deferred fees
and costs) from the Round 1 and Round 2 PPP loans in the current quarter. The
income recognized in the current quarter included $10.5 million acceleration of
net deferred fees in interest income resulting from the SBA forgiveness of
loans. Net deferred fees remaining on the balance of the PPP loans at September
30, 2021 were $13.0 million, which will be recognized into interest income over
the remaining life of the loans or when the loans are forgiven in whole or in
part by the SBA.

Supplemental information regarding credit quality and identification of the
Company's loan portfolio based on regulatory classification is provided in the
exhibits at the end of this press release. The regulatory classification of
loans is based primarily on collateral type while the Company's loan segments
presented herein are based on the purpose of the loan.

The current quarter provision for credit loss expense for loans was $2.3 million
which was an increase of $8.0 million from the prior quarter provision for
credit loss benefit of $5.7 million and a $556 thousand decrease from the prior
year third quarter provision for credit loss expense of $2.9 million. The
increase in provision for credit losses for loans in the current quarter
compared to the prior quarter was primarily driven by organic loan growth in the
current quarter.

The allowance for credit losses on loans ("ACL") as a percentage of total loans
outstanding at September 30, 2021 was 1.36 percent which was a 1 basis point
increase compared to the prior quarter and a 6 basis point decrease from the
prior year third quarter. Excluding the PPP loans, the ACL as percentage of
loans was 1.40 percent compared to 1.43 percent in the prior quarter and 1.62
percent in the prior year third quarter. The Company's ACL of $154 million is
considered adequate to absorb the estimated credit losses from any segment of
its loan portfolio. For the periods ended September 30, 2021 and 2020, the
Company believes the ACL is commensurate with the risk in the Company's loan
portfolio and is directionally consistent with the change in the quality of the
Company's loan portfolio.

While the Company has incorporated its estimate of the impact of the COVID-19
pandemic into its calculation of the allowance based on assumptions and
forecasts that existed as of the reporting period end, the uncertainty of the
current economic environment remains volatile and the Company cannot predict
whether additional credit losses will be sustained as a result of the COVID-19
pandemic if assumptions and forecasts change in the future.

--------------------------------------------------------------------------------


At the end of each quarter, the Company analyzes its loan portfolio and
maintains an ACL at a level that is appropriate and determined in accordance
with accounting principles generally accepted in the United States of America
("GAAP"). Determining the adequacy of the ACL involves a high degree of judgment
and is inevitably imprecise as the risk of loss is difficult to quantify. The
ACL methodology is designed to reasonably estimate the probable credit losses
within the Company's loan portfolio. Accordingly, the ACL is maintained within a
range of estimated losses. The determination of the ACL on loans, including
credit loss expense and net charge-offs, is a critical accounting estimate that
involves management's judgments about the loan portfolio that impact credit
losses, including the credit risk inherent in the loan portfolio, economic
forecasts nationally and in the local markets in which the Company operates,
trends and changes in collateral values, delinquencies, non-performing assets,
net charge-offs, credit-related policies and personnel, and other environmental
factors.

In determining the allowance, the loan portfolio is separated into pools of
loans that share similar risk characteristics which are the Company's loan
segments. The Company then derives estimated loss assumptions from its model by
loan segment which is further segregated by the credit quality indicators. The
loss assumptions are then applied to each segment of loan to estimate the ACL on
the pooled loans. For any loans that do not share similar risk characteristics,
the estimated credit losses are determined on an individual loan basis and such
loans primarily consist of non-accrual loans. An estimated credit loss is
recorded on individually reviewed loans when the fair value of a
collateral-dependent loan or the present value of the loan's expected future
cash flows (discounted at the loans original effective interest rate) is less
than the amortized cost of the loan.

The Company provides commercial banking services to individuals, small to
medium-sized businesses, community organizations and public entities from 194
locations, including 173 branches, across Montana, Idaho, Utah, Washington,
Wyoming, Colorado, Arizona and Nevada. The states in which the Company operates
have diverse economies and markets that are tied to commodities (crops,
livestock, minerals, oil and natural gas), tourism, real estate and land
development and an assortment of industries, both manufacturing and
service-related. Thus, the changes in the global, national, and local economies
are not uniform across the Company's geographic locations. The geographic
dispersion of these market areas helps to mitigate the risk of credit loss. The
Company's model of sixteen bank divisions with separate management teams is also
a significant benefit in mitigating and managing the Company's credit risk. This
model provides substantial local oversight to the lending and credit management
function and requires multiple reviews of larger loans before credit is
extended.

The primary responsibility for credit risk assessment and identification of
problem loans rests with the loan officer of the account. This continuous
process of identifying non-performing loans is necessary to support management's
evaluation of the ACL adequacy. An independent loan review function verifying
credit risk ratings evaluates the loan officer and management's evaluation of
the loan portfolio credit quality. The ACL evaluation is well documented and
approved by the Company's Board. In addition, the policy and procedures for
determining the balance of the ACL are reviewed annually by the Company's Board,
the internal audit department, independent credit reviewers and state and
federal bank regulatory agencies.

Although the Company continues to actively monitor economic trends and
regulatory developments, no assurance can be given that the Company will not, in
any particular period, sustain losses that are significant relative to the ACL
amount, or that subsequent evaluations of the loan portfolio applying
management's judgment about then current factors will not require significant
changes in the ACL. Under such circumstances, additional credit loss expense
could result.

For additional information regarding the ACL, its relation to credit loss expense and risk related to asset quality, see Note 3 to the Consolidated Financial Statements in "Part I. Item 1. Financial Statements."

Loans by Regulatory Classification
Supplemental information regarding identification of the Company's loan
portfolio and credit quality based on regulatory classification is provided in
the following tables. The regulatory classification of loans is based primarily
on the type of collateral for the loans. There may be differences when compared
to loan tables and loan amounts appearing elsewhere which reflect the Company's
internal loan segments which are based on the purpose of the loan.

The following table summarizes the Company's loan portfolio by regulatory
classification:

Sources of Funds
The Company's deposits have traditionally been the principal source of funds for
use in lending and other business purposes. The Company also obtains funds from
repayment of loans and debt securities, securities sold under agreements to
repurchase ("repurchase agreements"), wholesale deposits, advances from FHLB and
other borrowings. Loan repayments are a relatively stable source of funds, while
interest bearing deposit inflows and outflows are significantly influenced by
general interest rate levels and market conditions. Borrowings and advances may
be used on a short-term basis to compensate for reductions in normal sources of
funds such as deposit inflows at less than projected levels. Borrowings also may
be used on a long-term basis to support expanded activities, match maturities of
longer-term assets or manage interest rate risk.

Deposits


The Company has several deposit programs designed to attract both short-term and
long-term deposits from the general public by providing a wide selection of
accounts and rates. These programs include non-interest bearing deposit accounts
and interest bearing deposit accounts such as NOW, DDA, savings, money market
deposits, fixed rate certificates of deposit with maturities ranging from three
months to five years, negotiated-rate jumbo certificates, and individual
retirement accounts. These deposits are obtained primarily from individual and
business residents in the Bank's geographic market areas. Wholesale deposits are
obtained through various programs and include brokered deposits classified as
NOW, DDA, money market deposits and certificate accounts. The Company's deposits
are summarized below:

Securities Sold Under Agreements to Repurchase, Federal Home Loan Bank Advances
and Other Borrowings
The Company borrows money through repurchase agreements. This process involves
the selling of one or more of the securities in the Company's investment
portfolio and simultaneously entering into an agreement to repurchase the same
securities at an agreed upon later date, typically overnight. A rate of interest
is paid for the agreed period of time. The Bank enters into repurchase
agreements with local municipalities, and certain customers, and has adopted
procedures designed to ensure proper transfer of title and safekeeping of the
underlying securities. In addition to retail repurchase agreements, the Company
periodically enters into wholesale repurchase agreements as additional funding
sources. The Company has not entered into reverse repurchase agreements.

The Bank is a member of the FHLB of Des Moines, which is one of eleven banks
that comprise the FHLB system.  The Bank is required to maintain a certain level
of activity-based stock in order to borrow or to engage in other transactions
with the FHLB of Des Moines. Additionally, the Bank is subject to a membership
capital stock requirement that is based upon an annual calibration tied to the
total assets of the Bank. The borrowings are collateralized by eligible
categories of loans and debt securities (principally, securities which are
obligations of, or guaranteed by, the U.S. government and its agencies),
provided certain standards related to credit-worthiness have been met. Advances
are made pursuant to several different credit programs, each of which has its
own interest rates and range of maturities. The Bank's maximum amount of FHLB
advances is limited to the lesser of a fixed percentage of the Bank's total
assets or the discounted value of eligible collateral. FHLB advances fluctuate
to meet seasonal and other withdrawals of deposits and to expand lending or
investment opportunities of the Company.

Additionally, the Company has other sources of secured and unsecured borrowing lines from various sources that may be used from time to time.

Short-term borrowings
A critical component of the Company's liquidity and capital resources is access
to short-term borrowings to fund its operations. Short-term borrowings are
accompanied by increased risks managed by the Bank's Asset Liability Committee
("ALCO") such as rate increases or unfavorable change in terms which would make
it more costly to obtain future short-term borrowings. The Company's short-term
borrowing sources include FHLB advances, federal funds purchased and retail and
wholesale repurchase agreements. The Company also has access to the short-term
discount window borrowing programs (i.e., primary credit) of the Federal Reserve
Bank ("FRB"). FHLB advances and certain other short-term borrowings may be
renewed as long-term borrowings to decrease certain risks such as liquidity or
interest rate risk; however, the reduction in risks are weighed against the
increased cost of funds and other risks.

The following table provides information relating to significant short-term
borrowings, which consists of borrowings that mature within one year of period

Subordinated Debentures
In addition to funds obtained in the ordinary course of business, the Company
formed or acquired financing subsidiaries for the purpose of issuing trust
preferred securities that entitle the investor to receive cumulative cash
distributions thereon. Subordinated debentures were issued in conjunction with
the trust preferred securities and the terms of the subordinated debentures and
trust preferred securities are the same. For regulatory capital purposes, the
trust preferred securities are included in Tier 2 capital at September 30, 2021.
The subordinated debentures outstanding as of September 30, 2021 were $133
million, including fair value adjustments from acquisitions.

Contractual Obligations and Off-Balance Sheet Arrangements
In the normal course of business, there may be various outstanding commitments
to obtain funding and to extend credit, such as letters of credit and unfunded
loan commitments, which are not reflected in the accompanying condensed
consolidated financial statements. The Company assessed the off-balance sheet
credit exposures as of September 30, 2021 and determined its ACL of $14.1
million was adequate to absorb the estimated credit losses.

Off-balance sheet arrangements also include any obligation related to a variable
interest held in an unconsolidated entity. The Company does not anticipate any
material losses as a result of these transactions. For additional information
regarding the Company's interests in unconsolidated variable interest entities
("VIE"), see Note 7 to the Unaudited Consolidated Financial Statements in "Part
I. Item 1. Financial Statements."

Liquidity Risk
Liquidity risk is the possibility that the Company will not be able to fund
present and future obligations as they come due because of an inability to
liquidate assets or obtain adequate funding at a reasonable cost. The objective
of liquidity management is to maintain cash flows adequate to meet current and
future needs for credit demand, deposit withdrawals, maturing liabilities and
corporate operating expenses. Effective liquidity management entails three
elements:
1.assessing on an ongoing basis, the current and expected future needs for
funds, and ensuring that sufficient funds or access to funds exist to meet those
needs at the appropriate time;
2.providing for an adequate cushion of liquidity to meet unanticipated cash flow
needs that may arise from potential adverse circumstances ranging from high
probability/low severity events to low probability/high severity; and
3.balancing the benefits between providing for adequate liquidity to mitigate
potential adverse events and the cost of that liquidity.

The Company has a wide range of versatility in managing the liquidity and
asset/liability mix. The Bank's ALCO meets regularly to assess liquidity risk,
among other matters. The Company monitors liquidity and contingency funding
alternatives through management reports of liquid assets (e.g., debt
securities), both unencumbered and pledged, as well as borrowing capacity, both
secured and unsecured, including off-balance sheet funding sources. The Company
evaluates its potential funding needs across alternative scenarios and maintains
contingency funding plans consistent with the Company's access to diversified
sources of contingent funding.

The following table identifies certain liquidity sources and capacity available to the Company as of the dates indicated:

Capital Resources
Maintaining capital strength continues to be a long-term objective of the
Company. Abundant capital is necessary to sustain growth, provide protection
against unanticipated declines in asset values, and to safeguard the funds of
depositors. Capital is also a source of funds for loan demand and enables the
Company to effectively manage its assets and liabilities. The Company has the
capacity to issue 117,187,500 shares of common stock of which 95,512,659 have
been issued as of September 30, 2021. The Company also has the capacity to issue
1,000,000 shares of preferred stock of which none have been issued as of
September 30, 2021. Conversely, the Company may decide to utilize a portion of
its strong capital position, as it has done in the past, to repurchase shares of
its outstanding common stock, depending on market price and other relevant
considerations.

The Federal Reserve has adopted capital adequacy guidelines that are used to
assess the adequacy of capital in supervising a bank holding company. The
federal banking agencies issued final rules ("Final Rules") that established a
comprehensive regulatory capital framework based on the recommendation of the
Basel Committee on Banking Supervision and certain requirements of the
Dodd-Frank Wall Street Reform and Consumer Protection Act. The Final Rules
require the Company to hold a 2.5 percent capital conservation buffer designed
to absorb losses during periods of economic stress. As of September 30, 2021,
management believes the Company and Bank meet all capital adequacy requirements
to which they are subject and there are no conditions or events subsequent to
this date that management believes have changed the Company's or Bank's
risk-based capital category.

The following table illustrates the Bank's regulatory capital ratios and the Federal Reserve's capital adequacy guidelines as of September 30, 2021:

On January 1, 2020, the Company adopted the current expected credit losses
("CECL") accounting standard that requires management's estimate of credit
losses over the expected contractual lives of the Company's relevant financial
assets. On March 27, 2020, in response to the COVID-19 pandemic, federal banking
regulators issued an interim final rule to delay for two years the initial
adoption impact of CECL on regulatory capital, followed by a three-year
transition period to phase out the aggregate amount of the capital benefit
provided during 2020 and 2021 (i.e., a five-year transition period). The Company
has elected to utilize the five-year transition period. During the two-year
delay, the Company will add back to Common Tier 1 capital 100 percent of the
initial adoption impact of CECL plus 25 percent of the cumulative quarterly
changes in ACL (i.e., quarterly transitional amounts). Starting on January 1,
2022, the quarterly transitional amounts along with the initial adoption impact
of CECL will be phased out of Common Tier 1 capital evenly over the three-year
period.

Federal and State Income Taxes
The Company files a consolidated federal income tax return using the accrual
method of accounting. All required tax returns have been timely filed. Financial
institutions are subject to the provisions of the Internal Revenue Code of 1986,
as amended, in the same general manner as other corporations. The federal
statutory corporate income tax rate is 21 percent.

Within the Company's geographic footprint, Montana, Idaho, Utah, Colorado and
Arizona law, financial institutions are subject to a corporation income tax,
which incorporates or is substantially similar to applicable provisions of the
Internal Revenue Code. The corporation income tax is imposed on federal taxable
income, subject to certain adjustments. State taxes are incurred at the rate of
6.75 percent in Montana, 6.925 percent in Idaho, 4.95 percent in Utah, 4.6
percent in Colorado and 4.9 percent in Arizona. Washington, Wyoming and Nevada
do not impose a corporate income tax. The Company is also required to file in
the states other than the eight states in which it has properties.

______________________________


1The current and prior year's low effective income tax rates are due to income
from tax-exempt debt securities, municipal loans and leases and benefits from
federal income tax credits.

The Company has equity investments in Certified Development Entities ("CDE")
which have received allocations of New Markets Tax Credits ("NMTC").
Administered by the Community Development Financial Institutions Fund ("CDFI
Fund") of the U.S. Department of the Treasury, the NMTC program is aimed at
stimulating economic and community development and job creation in low-income
communities. The federal income tax credits received are claimed over a
seven-year credit allowance period. The Company also has equity investments in
Low-Income Housing Tax Credits ("LIHTC") which are indirect federal subsidies
used to finance the development of affordable rental housing for low-income
households. The federal income tax credits are claimed over a ten-year credit
allowance period. The Company has investments of $16.2 million in Qualified
School Construction bonds whereby the Company receives quarterly federal income
tax credits in lieu of taxable interest income. The federal income tax credits
on these debt securities are subject to federal and state income tax.

Following is a list of expected federal income tax credits to be received in the
years indicated.

Rate/Volume Analysis
Net interest income can be evaluated from the perspective of relative dollars of
change in each period. Interest income and interest expense, which are the
components of net interest income, are shown in the following table on the basis
of the amount of any increases (or decreases) attributable to changes in the
dollar levels of the Company's interest earning assets and interest bearing
liabilities ("volume") and the yields earned and paid on such assets and
liabilities ("rate"). The change in interest income and interest expense
attributable to changes in both volume and rates has been allocated
proportionately to the change due to volume and the change due to rate.

Net interest income (tax-equivalent) increased $42.6 million for the nine months
ended September 30, 2021 compared to the same period in 2020. The interest
income for the first nine months of 2021 increased over the same period last
year primarily from income associated with the PPP loans and increased volume of
debt securities. Total interest expense decreased from the prior year primarily
from a decrease in rates on deposits.

Effect of inflation and changing prices
GAAP often requires the measurement of financial position and operating results
in terms of historical dollars, without consideration for change in relative
purchasing power over time due to inflation. Virtually all assets of the Company
are monetary in nature; therefore, interest rates generally have a more
significant impact on a company's performance than does the effect of inflation.
