Pending Merger of First Interstate Bancorp and Great Western Bancorp

On September 16, 2021, First Interstate BancSystem, Inc. (NASDAQ:FIBK) ("FIBK"), parent company of First Interstate Bank, and GWBI, parent company of Great Western Bank, announced they have entered into a definitive agreement under which the companies will combine in an all‐stock transaction. Under the terms of the agreement, which was unanimously approved by both companies' Boards of Directors, GWBI will merge into FIBK and the combined holding company and bank will operate under the First Interstate name and brand with the company's headquarters remaining in Billings, Montana. Pending regulatory and shareholder approvals and the satisfaction of the closing conditions set forth in the agreement, the transaction is expected to close during the first calendar quarter of 2022.

Net Interest Income and Net Interest Margin¹

Net interest income was $95.1 million for the quarter, down $4.0 million, while net interest margin was 3.10%, a 13 basis point decrease from 3.23%. Adjusted net interest income², which includes derivative interest expense recognized in noninterest income, was $92.0 million, down $3.9 million, and adjusted net interest margin² was 3.00%, a 13 basis point decrease from 3.13%. Interest income was lower by $4.7 million as loan interest decreased by $5.3 million while securities and other interest income increased by $0.6 million. Loan interest reflects a $0.9 million decrease in PPP interest and fees, a $1.0 million decrease in recoveries of interest on nonaccrual loans, and a $3.4 million net decrease from lower volumes and lower yields, all partially offset with a $0.6 million increase in securities and other interest driven largely by increased volumes. The decrease in net interest income was partially offset by a $0.2 million decrease in time deposit interest combined with a net $0.6 million decrease in interest on other interest bearing deposits. The decrease in time deposit interest resulted from a decrease in volumes and a 4 basis point decrease in yield to 0.37%, while the decrease in interest on other interest bearing deposits was driven primarily by a 2 basis point decrease in yield of interest bearing deposits to 0.11%. The 13 basis point decrease in adjusted net interest margin² was driven by an 8 basis point decrease from excess liquidity and a 7 basis point net decrease from lower loan and securities yields and lower recoveries of interest on nonaccrual loans, all partially offset by a 2 basis point impact from lower deposit costs.

Noninterest Income

Noninterest income was $15.9 million for the quarter, down $3.5 million from the prior quarter. This was driven mainly by a net $3.8 million decrease in adjustments for loans and derivatives accounted for at fair value related to credit risk. Excluding those fair value adjustments, the $0.2 million increase in noninterest income was driven by a $0.9 million increase in service charges from increased account activity and interchange fees and a $0.1 million increase in wealth management fees, partially offset by a $0.8 million decrease in mortgage revenue from slower refinancing and purchase activity.

Noninterest Expense

Noninterest expense was $63.7 million for the quarter, up $3.2 million from the prior quarter. The increase was driven by $5.2 million in merger-related costs included within professional fees and a $0.6 million increase in data processing costs related to software maintenance and upgrades. These were partially offset by a $2.9 million decrease in salaries and benefits due to lower incentive accruals and a $0.6 million decrease in other real estate owned operating costs due to the gain on sale of an OREO property.

The efficiency ratio² was 57.2% for the quarter, compared to 50.9% for the prior quarter.

Provision for Income Taxes

Income tax expense was $14.7 million for the quarter, down $3.6 million from the prior quarter, yielding an effective rate of 22.1% compared to 23.7%.

Asset Quality

The ACL was $246.0 million as of September 30, 2021, down $24.3 million from $270.3 million in the prior quarter. The provision for credit losses on loans resulted in a $20.9 million benefit for the quarter, compared to a $20.7 million benefit in the prior quarter, due to lower loan volumes and improved economic factors.

The ratio of ACL to total loans was 3.01% as of September 30, 2021, down from 3.19% in the prior quarter. Excluding PPP loans, the ratio was 3.09% for the current quarter and 3.33% for the prior quarter.

Net charge-offs were $4.1 million, or 0.20% of average total loans (annualized) for the quarter, down $1.1 million and 4 basis points from the prior quarter, respectively.

Included within total loans are approximately $524.5 million of loans with long-term, fixed rate structures for which management has elected the fair value accounting option, down from $545.1 million in the prior quarter. These loans are excluded from CECL and the ACL, but management has estimated that approximately $22.3 million of the fair value adjustment for these loans relates to credit risk, which is 4.26% of the fair value option loans and 0.28% of total loans excluding PPP loans, compared to $23.3 million of the fair value adjustment for these loans related to credit risk in the prior quarter, which was 4.28% of the fair value option loans and 0.29% of total loans excluding PPP loans.

Nonaccrual loans were $197.9 million as of September 30, 2021, down $12.2 million from $210.1 million in the prior quarter, largely driven by repayments on multiple agricultural and commercial nonaccrual loans.

Classified loans were $604.9 million as of September 30, 2021, down $7.3 million from $612.2 million in the prior quarter, and special mention loans were $351.5 million as of September 30, 2021, down $23.3 million.

Total other repossessed property balances were $4.5 million as of September 30, 2021, down $7.0 million from the prior quarter due largely to the sale of an OREO property.

A summary of total credit-related charges incurred during the current and comparable twelve month periods and current, previous and comparable quarters is presented below:

We continue to evaluate the impact of the COVID-19 pandemic on our loan portfolio. Industries such as hotels & resorts (excluding casino hotels), casino hotels, restaurants, arts and entertainment, oil & energy, retail malls, airlines and healthcare have experienced varied business disruptions due to COVID-19. Since the beginning of the pandemic we have been closely monitoring the following loan segments (excluding PPP loans) given elevated industry risk from COVID-19: hotels & resorts (excluding casino hotels) with $619.1 million, or 7.7% of total loans, restaurants with $125.7 million, or 1.6% of total loans, arts and entertainment with $159.0 million, or 2.0% of total loans, senior care with $368.0 million, or 4.6% of total loans, and skilled nursing with $206.9 million, or 2.6% of total loans, all as of September 30, 2021, with $195.2 million of these loans being classified as of September 30, 2021 and loan exposure in other segments of the identified industries being either immaterial or having not shown general distress thus far.

Loans and Deposits

Total loans outstanding were $8.19 billion as of September 30, 2021, down $292.7 million from the prior quarter. The decrease in loans during the quarter was driven by a $152.9 million net decrease in PPP loans, a $132.4 million decrease from repayments on several criticized and specialized asset hotel loans, and a net decrease across retail and commercial loan segments related to business sales and excess liquidity.

We have supported PPP, having provided over 4,800 loans for $727.3 million in the first round followed by over 4,100 loans for $249.5 million in the second round. We have processed over 6,900 loans totaling $764.8 million related to PPP forgiveness, resulting in an outstanding balance of $212.0 million as of September 30, 2021.

Total deposits were $11.31 billion as of September 30, 2021, down $227.3 million from the prior quarter, driven by a $167.3 million decrease in other interest-bearing deposits, a $44.6 million decrease in time deposits, and a $15.4 million decrease in checking and savings balances.

Capital

Total capital and tier 1 capital ratios were 16.3% and 15.1%, respectively, as of September 30, 2021, compared to 16.0% and 14.5% as of June 30, 2021. The common equity tier 1 capital and tier 1 leverage ratios were 14.3% and 10.6%, respectively, as of September 30, 2021, compared to 13.7% and 10.1% as of June 30, 2021. All regulatory capital ratios remain above regulatory minimums to be considered "well capitalized."

On October 26, 2021, the Company's Board of Directors declared a dividend of $0.05 per common share, payable on November 26, 2021 to stockholders of record as of close of business on November 12, 2021.

In particular, the statements included in this press release concerning GWBI's expected performance and strategy, strategies for managing troubled loans, the appropriateness of the ACL, the impact on the business arising from the COVID-19 pandemic, the interest rate environment and the business combination transaction between GWBI and FIBK (the "Transaction") are not historical facts and are forward-looking. Accordingly, the forward-looking statements in this press release are only predictions and involve estimates, known and unknown risks, assumptions and uncertainties that could cause actual results to differ materially from those expressed. All forward-looking statements are necessarily only estimates of future results, and there can be no assurance that actual results will not differ materially from expectations, and, therefore, you are cautioned not to place undue reliance on such statements. In addition to factors previously disclosed in GWBI's and FIBK's reports filed with the U.S. Securities and Exchange Commission (the "SEC") and those identified elsewhere in this press release, the following factors, among others, could cause actual results to differ materially from forward-looking statements or historical performance: the occurrence of any event, change or other circumstance that could give rise to the right of one or both of the parties to terminate the definitive merger agreement between GWBI and FIBK; the outcome of any legal proceedings that may be instituted against GWBI or FIBK; the possibility that the Transaction does not close when expected or at all because required regulatory, shareholder, or other approvals and other conditions to closing are not received or satisfied on a timely basis or at all (and the risk that such approvals may result in the imposition of conditions that could adversely affect the combined company or the expected benefits of the Transaction); the risk that the benefits from the Transaction may not be fully realized or may take longer to realize than expected, including as a result of changes in, or problems arising from, general economic and market conditions, interest and exchange rates, monetary policy, laws and regulations and their enforcement, and the degree of competition in the geographic and business areas in which GWBI and FIBK operate; the ability to promptly and effectively integrate the businesses of GWBI and FIBK; the possibility that the Transaction may be more expensive to complete than anticipated, including as a result of unexpected factors or events; reputational risk and potential adverse reactions of GWBI's or FIBK's customers, employees or other business partners, including those resulting from the announcement or completion of the Transaction; the dilution caused by FIBK's issuance of additional shares of its capital stock in connection with the Transaction; the diversion of management's attention and time from ongoing business operations and opportunities on merger-related matters; and the impact of the global COVID-19 pandemic on GWBI's and FIBK's businesses, the ability to complete the Transaction or any of the other foregoing risks. These factors are not necessarily all of the factors that could cause GWBI's, FIBK's or the combined company's actual results, performance, or achievements to differ materially from those expressed in or implied by any of the forward-looking statements.

Non-GAAP Financial Measures and Reconciliation

We rely on certain non-GAAP financial measures in making financial and operational decisions about our business. We believe that each of the non-GAAP financial measures presented is helpful in highlighting trends in our business, financial condition and results of operations which might not otherwise be apparent when relying solely on our financial results calculated in accordance with GAAP. We disclose net interest income and related ratios and analysis on a taxable-equivalent basis, which may also be considered non-GAAP financial measures. We believe this presentation to be the preferred industry measurement of net interest income as it provides a relevant comparison of net interest income arising from taxable and tax-exempt sources. In addition, certain performance measures, including the efficiency ratio and net interest margin utilize net interest income on a taxable-equivalent basis.

In particular, we evaluate our profitability and performance based on our adjusted net income, adjusted earnings per common share, pre-tax pre-provision income ("PTPP"), tangible net income and return on average tangible common equity. Our adjusted net income and adjusted earnings per common share exclude the after-tax effect of items with a significant impact to net income that we do not believe to be recurring in nature, (e.g., one-time acquisition expenses as well as the second quarter of fiscal year 2020 COVID-19 impact on credit and other related charges and the impairment of goodwill and certain intangible assets). Our PTPP income excludes total provision for credit losses, credit gains/losses on loans held for investment measured at fair value and goodwill impairment. Our tangible net income and return on average tangible common equity exclude the effects of amortization expense relating to intangible assets and our acquisitions of other institutions. We believe these measures help highlight trends associated with our financial condition and results of operations by providing net income and return information excluding significant nonrecurring items (for adjusted net income and adjusted earnings per common share), measure our ability to generate capital by providing net income excluding credit losses (for PTPP income) and measure net income based on our cash payments and receipts during the applicable period (for tangible net income and return on average tangible common equity).

We also evaluate our profitability and performance based on our adjusted net interest income, adjusted net interest margin, adjusted interest income on loans and adjusted yield on loans. We adjust each of these four measures to include the derivative interest expense we use to manage interest rate risk on certain of our loans, which we believe economically offsets the interest income earned on the loans. Similarly, we evaluate our operational efficiency based on our efficiency ratio, which excludes the effect of amortization of core deposit and other intangibles (a non-cash expense item) and includes the tax benefit associated with our tax-advantaged loans.

We evaluate our financial condition based on the ratio of our tangible common equity to our tangible assets and the ratio of our tangible common equity to common shares outstanding. Our calculation of this ratio excludes the effect of our goodwill and other intangible assets. We believe this measure is helpful in highlighting the common equity component of our capital and because of its focus by federal bank regulators when reviewing the health and strength of financial institutions in recent years and when considering regulatory approvals for certain actions, including capital actions. We also believe the ratio of our tangible common equity to common shares outstanding is helpful in understanding our stockholders' relative ownership position as we undertake various actions to issue and retire common shares outstanding.

Reconciliations for each of these non-GAAP financial measures to the closest GAAP financial measures are included in the tables below. Each of the non-GAAP financial measures presented should be considered in context with our GAAP financial results included in this release.
