WEST BANCORPORATION, INC. ANNOUNCES FOURTH QUARTER AND YEAR END 2022 FINANCIAL RESULTS, DECLARES QUARTERLY DIVIDEND

West Des Moines, IA - West Bancorporation, Inc. (Nasdaq: WTBA; the “Company”), parent company of West Bank, today reported 2022 net income of $46.4 million, or $2.76 per diluted common share, compared to 2021 net income of $49.6 million, or $2.95 per diluted common share. Net income for the fourth quarter 2022 was $8.9 million, or $0.53 per diluted common share, compared to fourth quarter 2021 net income of $11.9 million, or $0.71 per diluted common share. On January 25, 2023, the Company’s Board of Directors declared a regular quarterly dividend of $0.25 per common share. The dividend is payable on February 22, 2023, to stockholders of record on February 8, 2023.

David Nelson, President and Chief Executive Officer of the Company, commented, “Our company had another strong year, the second best year in our company’s history. Our credit quality continues to be pristine and we remain diligent in monitoring and managing our credit risk as we anticipate increasing economic challenges resulting from the Federal Reserve’s aggressive interest rate hikes in 2022. Loan growth in 2022 exceeded eleven percent and for the sixth consecutive quarter end, we had no loans greater than 30 days past due.”

David Nelson added, “Rising interest rates in 2022 have increased the average yield of our loan portfolio. However, changes in liquidity and competitive deposit pricing, as a result of volatility and uncertainty in the interest rate environment, have increased our cost of funds and resulted in a decline in our net interest income and net interest margin. We expect to continue to experience a lower than normal net interest margin while the Federal Reserve continues raising short-term rates. Our capital position is strong and we remain focused on delivering high quality services and products through our very successful relationship based business model.”

Fourth Quarter and Year Ended 2022 Financial Highlights

	Quarter Ended December 31, 2022		Year Ended December 31, 2022
Net Income (in thousands)	$8,946		$46,399
Return on Average Equity	17.75	%	20.71	%
Return on Average Assets	1.01	%	1.32	%
Efficiency ratio (a non-GAAP measure)	50.42	%	43.70	%
Nonperforming assets to total assets	0.01	%	0.01	%

Fourth Quarter 2022 Compared to Third Quarter 2022 Overview

•Loans increased $128.7 million in the fourth quarter of 2022, or 19.7 percent annualized.

•No provision for loan losses was recorded in either the fourth quarter of 2022 or the third quarter of 2022.

•The allowance for loan losses to total loans was 0.93 percent at December 31, 2022, compared to 0.97 percent at September 30, 2022. There were no loans greater than 30 days past due at December 31, 2022, which was the sixth consecutive quarter in which no loans were greater than 30 days past due. Nonaccrual loans at December 31, 2022, consisted of one loan with a balance of $322 thousand.

•Deposits increased $57.6 million in the fourth quarter of 2022. Included in deposits were brokered deposits totaling $272.7 million at December 31, 2022, compared to $258.1 million at September 30, 2022.

•The efficiency ratio (a non-GAAP measure) was 50.42 percent for the fourth quarter of 2022, compared to 43.16 percent for the third quarter of 2022. The increase in the efficiency ratio is primarily the result of the decline in tax equivalent net interest income.

•Net interest margin, on a fully tax-equivalent basis (a non-GAAP measure), was 2.49 percent for the fourth quarter of 2022, compared to 2.78 percent for the third quarter of 2022. Net interest income for the fourth quarter of 2022 was $20.7 million, compared to $23.0 million for the third quarter of 2022. The rising cost of deposits and borrowed funds and the change in mix of liabilities has increased interest expense faster than the increase in interest income from loan repricing and loan growth.

•The tangible common equity ratio was 5.84 percent at December 31, 2022, an increase of 19 basis points compared to 5.65 percent at September 30, 2022 due to a modest increase in the market value of the securities portfolio, which decreased the accumulated other comprehensive loss.

Fourth Quarter 2022 Compared to Fourth Quarter 2021 Overview

•Loans increased $286.6 million at December 31, 2022, or 11.7 percent, compared to December 31, 2021.

•Deposits decreased $135.6 million at December 31, 2022, compared to December 31, 2021. Included in deposits were brokered deposits totaling $272.7 million at December 31, 2022, compared to $176.0 million at December 31, 2021. The decline in deposits was primarily attributable to customers using their own liquidity to fund business transactions, instead of using debt, and customers seeking higher yielding investment options for excess deposits accumulated over the past couple of years.

•Borrowed funds increased to $485.9 million at December 31, 2022, compared to $199.9 million at December 31, 2021. The increase included $58.9 million in subordinated notes that were issued in June 2022, $30.0 million in FHLB Advances associated with a long-term interest rate swap and $197.1 million in federal funds purchased and other short-term borrowings.

•The efficiency ratio (a non-GAAP measure) was 50.42 percent for the fourth quarter of 2022, compared to 43.32 percent for the fourth quarter of 2021. Tax-equivalent net interest income decreased in the fourth quarter of 2022 compared to the fourth quarter of 2021 due to the increased cost of deposits and borrowed funds. Additionally, salaries and benefits were higher in the fourth quarter of 2022 compared to the fourth quarter of 2021, due primarily to annual compensation adjustments.

•Net interest margin, on a fully tax-equivalent basis (a non-GAAP measure), was 2.49 percent for the fourth quarter of 2022, compared to 3.00 percent for the fourth quarter of 2021. Net interest income for the fourth quarter of 2022 was $20.7 million, compared to $24.6 million for the fourth quarter of 2021. Net interest income in the fourth quarter of 2021 included $912 thousand of PPP loan interest income, compared to $5 thousand in the fourth quarter of 2022. In 2022, the rising cost of deposits and borrowed funds and the change in mix of liabilities has increased interest expense faster than the increase in interest income from loan repricing and loan growth.

Year Ended 2022 Compared to Year Ended 2021 Overview

•The provision for loan losses recorded in 2022 was negative $2.5 million, compared to a negative provision of $1.5 million in 2021. The negative provision in 2022 was primarily due to the reversal of a specific reserve on an impaired loan and the reduction of certain qualitative factors resulting from the sustained performance of loans after the expiration of COVID-19 modifications and continued improvement in classified loans. The negative provision in 2021 was primarily due to the reduction of certain qualitative factors resulting from improvements in economic conditions and lack of loan losses during the COVID-19 pandemic.

•Net interest income declined $3.3 million, or 3.5 percent, in 2022 compared to 2021. Net interest margin decreased to 2.76 percent in 2022, compared to 3.05 percent in 2021. The decline in both net interest income and net interest margin was primarily due to the rising cost of deposits and borrowed funds and the change in mix of liabilities, which has increased interest expense faster than the increase in interest income from loan repricing and loan growth.

•Noninterest income increased $479 thousand, or 4.9 percent, in 2022 compared to 2021. This increase was primarily due to the increase in loan swap fees.

•Noninterest expense increased $1.7 million, or 3.9 percent, in 2022 compared to 2021. The increase was primarily due to an increase of $2.6 million, or 11.2 percent, in salaries and benefits resulting from an increase in expenses related to the issuance of restricted stock units, an increase in full time equivalent employees and annual compensation adjustments. This was partially offset by a decrease of $822 thousand in FDIC insurance expense primarily due to reductions in the assessment rate resulting from capital injections into the Bank.

NON-GAAP FINANCIAL MEASURES

This report contains references to financial measures that are not defined in GAAP. Such non-GAAP financial measures include the Company’s presentation of net interest income and net interest margin on a fully taxable equivalent (FTE) basis and the presentation of the efficiency ratio on an adjusted and FTE basis, excluding certain income and expenses. Management believes these non-GAAP financial measures provide useful information to both management and investors to analyze and evaluate the Company’s financial performance. These measures are considered standard measures of comparison within the banking industry. Additionally, management believes providing measures on a FTE basis enhances the comparability of income arising from taxable and nontaxable sources. Limitations associated with non-GAAP financial measures include the risks that persons might disagree as to the appropriateness of items included in these measures and that different companies might calculate these measures differently. These non-GAAP disclosures should not be considered an alternative to the Company’s GAAP results. The following table reconciles the non-GAAP financial measures of net interest income and net interest margin on a fully taxable equivalent basis and efficiency ratio on an adjusted and FTE basis.

(1)    Computed on a tax-equivalent basis using a federal income tax rate of 21 percent, adjusted to reflect the effect of the nondeductible interest expense associated with owning tax-exempt securities and loans. Management believes the presentation of this non-GAAP measure provides supplemental useful information for proper understanding of the financial results, as it enhances the comparability of income arising from taxable and nontaxable sources.

(2)     The efficiency ratio expresses noninterest expense as a percent of fully taxable equivalent net interest income and noninterest income, excluding specific noninterest income and expenses. Management believes the presentation of this non-GAAP measure provides supplemental useful information for proper understanding of the Company's financial performance. It is a standard measure of comparison within the banking industry. A lower ratio is more desirable.
