FIRST BUSINESS BANK REPORTS THIRD QUARTER 2023 NET INCOME OF $9.7 MILLION

-- Robust pre-tax pre-provision earnings supported by strong balance sheet growth and diversified revenue --

MADISON, Wis., October 26, 2023 (BUSINESS WIRE) -- First Business Financial Services, Inc. (the “Company”, the “Bank”, or “First Business Bank”) (Nasdaq:FBIZ) reported quarterly net income available to common shareholders of $9.7 million, or earnings per share of $1.17 on a diluted basis. This compares to net income available to common shareholders of $8.1 million, or $0.98 per share, in the second quarter of 2023 and $10.6 million, or $1.25 per share, in the third quarter of 2022.

“First Business Bank again delivered exceptional double-digit loan and in-market deposit growth during the third quarter, which supports our long-term objectives of revenue expansion and deepening client relationships,” said Corey Chambas, Chief Executive Officer. “We continue to diversify our drivers of profitability, including client deposit initiatives to grow treasury management sales and tax credit opportunities with commercial real estate clients, which have effectively lowered our tax rate while also benefiting the communities where we live and serve. With bottom line earnings up nearly 20% from the second quarter, we are pleased to have generated 13% annualized growth in tangible book value per share, a key measure of shareholder value.”

“Solid strategic planning and outstanding execution have allowed us to grow both loans and deposits in excess of 10% over the last several years,” Chambas added. “Our recent completion of a $15 million subordinated debt offering bolstered our capacity to continue pursuing quality loan and deposit growth. We continue to evaluate loan sale strategies, and we expect overall loan growth to moderate in 2024 as we manage to our long-term target of 10%.”

Quarterly Highlights

•Strong Deposit Growth. Total deposits grew $128.2 million, increasing 20.3% annualized from the second quarter and $569.5 million, or 27.3% from the third quarter of 2022. In-market deposits grew to a record $2.189 billion, up $115.5 million, or 22.3% annualized, from the second quarter and $260.0 million, or 13.5% from the third quarter of 2022. Strong seasonal client deposit activity contributed to increased gross treasury management service charges, which grew 14.5% to $1.5 million, compared to the third quarter of 2022.

•Robust Loan Growth. Loans grew $89.4 million, or 13.4% annualized, from the second quarter of 2023, and $433.3 million, or 18.6%, from the third quarter of 2022, reflecting ongoing expansion across the Company’s products and geographies in the third quarter.

•Net Interest Income Expansion. Net interest income grew 3.1% from the linked quarter and 10.5% from the prior year quarter. Consistent execution of the Company’s strategy to drive diversified loan portfolio growth supported this expansion even as industry-wide net interest margin compression continued. Net interest margin of 3.76% declined five basis points from the linked quarter. Importantly, adjusted1 net interest margin of 3.66% increased three basis points from the linked quarter.

•Strong Pre-Tax, Pre-Provision (“PTPP”) Income. PTPP income grew to $14.1 million, up 4.5% from the prior quarter. This performance reflects solid growth across the Company’s balance sheet and diversified sources of non-interest income. PTPP adjusted return on average assets measured 1.72% for the current and linked quarter.

•Tangible Book Value Growth. The Company’s strong earnings generation produced a 13.0% annualized increase in tangible book value per share compared to the linked quarter and 13.8% compared to the prior year quarter.

Exhibit 99.1

Third Quarter 2023 Compared to Second Quarter 2023

Net interest income increased $849,000, or 3.1%, to $28.6 million.

•The increase in net interest income was driven by an increase in average loans and leases receivable, partially offset by a decrease in fees in lieu of interest. Average loans and leases receivable increased $128.6 million, or 19.9% annualized, to $2.712 billion. Fees in lieu of interest, which vary from quarter to quarter based on client-driven activity, totaled $582,000, compared to $936,000 in the prior quarter. Excluding fees in lieu of interest, net interest income increased $1.2 million, or 4.5%.

•The yield on average interest-earning assets increased 24 basis points to 6.71% from 6.47%. Excluding fees in lieu of interest, the yield earned on average interest-earning assets increased 28 basis points to 6.63% from 6.35%. The daily average effective federal funds rate increased 27 basis points compared to the linked quarter, which equates to an average adjusted interest-earning asset beta of 104.8% for the three months ended September 30, 2023, compared to 73.9% in the linked quarter. The cumulative adjusted interest-earning asset beta since December 31, 2021 was 59.7%. The change in yield of the respective interest-earning asset or the rate paid on interest-bearing liability compared to the change in short-term market rates is commonly referred to as a beta.

•The rate paid for average interest-bearing, in-market deposits increased 49 basis points to 3.74% from 3.25% due to the acceleration of exception pricing and the shift of client balances from non-interest bearing deposits to certificates of deposit and interest-bearing demand deposit accounts. Similarly, the rate paid for average total bank funding increased 29 basis points to 3.07% from 2.78%. Total bank funding is defined as total deposits plus Federal Home Loan Bank (“FHLB”) advances. The total bank funding beta was 107.5% for the three months ended September 30, 2023, compared to 98.9% in the linked quarter. The cumulative bank funding beta since December 31, 2021 was 52.9%.

•Net interest margin was 3.76%, down 5 basis points compared to 3.81% in the linked quarter. Adjusted net interest margin1 was 3.66%, up 3 basis points compared to 3.63% in the linked quarter. The increase in adjusted net interest margin was due to an increase in the yield on average adjusted interest earning assets, partially offset by the rate paid on total bank funding.

•The Bank anticipates deposit betas may continue to rise and net interest margin may continue to decline at a gradual pace in coming quarters as the Federal Open Market Committee approaches a terminal federal funds rate. Based on current trends, we believe our net interest margin should stabilize above our existing strategic plan goal of 3.50%.

The Bank reported a provision expense of $1.8 million, compared to $2.2 million in the second quarter of 2023. The third quarter provision expense included increases of $1.3 million in net specific reserves, $817,000 due to exceptional loan growth, net charge-offs of $478,000, and qualitative factor changes of $506,000. This expense was partially offset by a $1.4 million reduction in general reserve due to an improved economic outlook in our model forecast compared to the prior period. Similar to the second quarter, the increase in specific reserves, charge-offs, and qualitative factors was primarily related to the Equipment Finance and SBA Lending loan pools, which management believes is consistent with the cyclical nature of these commercial lending niches.

Non-interest income increased $1.1 million, or 14.3%, to $8.4 million.

•Private Wealth and Company Retirement Plan (“Private Wealth”) fee income increased $52,000, or 1.8% to $2.9 million. Private Wealth assets under management and administration measured $2.915 billion on September 30, 2023, up $7.5 million from the prior quarter.

•Gains on sale of SBA loans increased $407,000, or 91.7%, to $851,000 driven by volume of loan sales.

•Other fee income increased $587,000 to $2.0 million, compared to $1.4 million in the prior quarter. The increase was primarily due to higher returns on the Company’s investments in mezzanine funds in the third quarter. Income from mezzanine funds was $1.2 million in the third quarter, compared to $389,000 in the linked quarter. Income from mezzanine funds varies from period to period based on changes in the value of underlying investments. Investment values are primarily reflected in our results semiannually, in the first and third quarters.

•Loan fee income decreased $119,000, or 13.1%, to $786,000 primarily due to a decrease in Asset-Based Lending (“ABL”) audit fee income.

1 Adjusted net interest margin is a non-GAAP measure representing net interest income excluding fees in lieu of interest and other recurring, but volatile, components of net interest margin divided by average interest-earning assets less other recurring, but volatile, components of average interest-earning assets.

Exhibit 99.1

Non-interest expense increased $1.2 million, or 5.3%, to $23.2 million, while operating expense increased $1.3 million, or 5.8%, to $22.9 million.

•Compensation expense was $15.6 million, reflecting an increase of $444,000, or 2.9%, from the linked quarter primarily due to a $510,000 increase in the annual cash incentive bonus and profit sharing accruals and an increase in employee salaries. This increase was partially offset by a decrease in share-based compensation following the second quarter vesting of performance-based restricted stock units (“PRSU”). Average full-time equivalents (FTEs) for the third quarter of 2023 were 349, up from 341 in the linked quarter.

•Professional fees were $1.4 million, increasing $189,000, or 15.2%, from the linked quarter primarily due to an increase in recruiting expenses.

•FDIC insurance expense was $680,000, increasing $100,000, or 17.2%, from the linked quarter primarily due to an increase in the assessment rate and the assessable base.

•Other non-interest expense increased $496,000, or 45.6%, to $1.6 million from the linked quarter primarily due to a $693,000 increase in liquidation expense related to an ABL loan relationship. In past resolutions, the Bank has been able to recover similar liquidation expenses. These increases were partially offset by a decrease in travel expense and a loss on disposal of fixed assets in the prior quarter.

Income tax expense decreased $443,000, or 17.6%, to $2.1 million. The effective tax rate was 17.3% for the three months ended September 30, 2023, compared to 23.2% for the linked quarter. Both periods benefited from net tax credits of $797,000 and $150,000 in the current and linked quarters, respectively. Based on expected earnings and future tax credit investments, the Company expects to report an effective tax rate between 21% and 22% for 2023 and between 20% and 21% for 2024.

Total period-end loans and leases receivable increased $89.4 million, or 13.4% annualized, to $2.764 billion. Management expects loan growth to moderate to our long term target of 10% in future quarters. Additionally, management is evaluating loan sale and participation strategies as a means of adding to and further diversifying fee income. The average rate earned on average loans and leases receivable was 7.06%, up 20 basis points from 6.86% in the prior quarter.

•Commercial Real Estate (“CRE”) loans increased by $43.6 million, or 11.0% annualized, to $1.635 billion. The increase was primarily due to an increase in non-owner occupied CRE and multi-family loans.

•Commercial & Industrial (“C&I”) loans increased $46.8 million, or 18.0% annualized, to $1.084 billion. The increase was due to growth across the majority of the Bank’s C&I products and geographies.

Total period-end in-market deposits increased $115.5 million, or 22.3% annualized, to $2.189 billion, compared to $2.074 billion. The average rate paid was 2.97%, up 41 basis points from 2.56% in the prior quarter.

•The increase was due to growth in interest-bearing transaction accounts, money market accounts, and non-interest bearing transaction accounts, partially offset by a decrease in certificates of deposit.

Period-end wholesale funding, including FHLB advances, brokered deposits, and deposits gathered through internet deposit listing services, decreased $8.6 million, or 4.4% annualized, to $782.2 million.

•Wholesale deposits increased $12.6 million to $467.7 million, compared to $455.1 million as the Bank continued to replace FHLB advances with wholesale deposits consistent with the Company’s long-held philosophy to manage interest rate risk by utilizing the most efficient and cost-effective source of wholesale funds to match-fund fixed-rate loans. The average rate paid on wholesale deposits decreased 17 basis points to 4.07% and the weighted average original maturity increased to 4.0 years from 3.7 years.

•FHLB advances decreased $21.2 million to $314.5 million. The average rate paid on FHLB advances decreased 19 basis points to 2.48% and the weighted average original maturity was 5.2 years for both periods.

Exhibit 99.1

Non-performing assets increased $1.9 million to $17.7 million, or 0.52% of total assets, up from 0.48% in the prior quarter driven by Equipment Finance loans within the C&I portfolio. We continue to expect full repayment of the one ABL loan that defaulted during the second quarter of 2023. Excluding the ABL loan, non-performing assets totaled $8.1 million, or 0.24% of total assets in the current quarter and $4.9 million, or 0.15% of total assets in the linked quarter. The increase in the Equipment Finance pool, for which defaults and liquidations are not atypical, was due to a cyclical increase in past-due balances.

The allowance for credit losses, including unfunded credit commitments reserve, increased $1.3 million, or 4.5%, as increases in specific reserves, the general reserve from loan growth, and qualitative factors were partially offset by a decrease in the general reserve due to an improved economic outlook in our model forecast. The allowance for credit losses, including unfunded credit commitment reserves, as a percent of total gross loans and leases was 1.12% compared to 1.11% in the prior quarter.

Third Quarter 2023 Compared to Third Quarter 2022

Net interest income increased $2.7 million, or 10.5%, to $28.6 million.

•The increase in net interest income primarily reflects an increase in average gross loans and leases, partially offset by lower fees in lieu of interest and net interest margin compression. Fees in lieu of interest decreased from $807,000 to $582,000. Excluding fees in lieu of interest, net interest income increased $2.9 million, or 11.7%.

•The yield on average interest-earning assets measured 6.71% compared to 4.92%. Excluding fees in lieu of interest, the yield on average interest-earning assets measured 6.63%, compared to 4.80%. This increase in yield was primarily due to the increase in short-term market rates and the reinvestment of cash flows from the securities and fixed rate loan portfolios in a rising rate environment. The daily average effective federal funds rate increased 308 basis points compared to the prior year quarter, which equates to an average adjusted interest-earning asset beta of 59.5% for the three months ended September 30, 2023, compared to the prior year period.

•The rate paid for average interest-bearing in-market deposits increased 286 basis points to 3.74% from 0.88%. The rate paid for average total bank funding increased 218 basis points to 3.07% from 0.89%. The total bank funding beta was 70.8% for the three months ended September 30, 2023, compared to the prior year period.

•Net interest margin decreased 25 basis points to 3.76% from 4.01%. Adjusted net interest margin decreased 23 basis points to 3.66% from 3.89%.

The Company reported a provision expense of $1.8 million, compared to $12,000 in the third quarter of 2022. The prior year period provision benefited from net recoveries.

Non-interest income of $8.4 million increased by $233,000, or 2.8%, from $8.2 million in the prior year period.

•Private Wealth fee income increased $327,000, or 12.5%, to $2.9 million. Private Wealth assets under management and administration measured $2.915 billion at September 30, 2023, up $422.0 million, or 16.9%.

•Commercial loan swap fee income of $992,000 increased by $651,000, or 190.9%. Swap fee income varies from period to period based on loan activity and the interest rate environment.

•Gain on sale of SBA loans increased $119,000, or 16.3%, to $851,000.

•Service charges on deposits decreased $183,000, or 18.0%, to $835,000, driven by an increase in the earnings credit rate commensurate with the rising rate environment.

•Other fee income decreased $653,000, or 24.4%, to $2.0 million, primarily due to higher returns on the Company’s investments in mezzanine funds and a gain on customer lease restructuring in the prior year quarter. Income from mezzanine funds was $1.2 million in the third quarter, compared to $1.4 million in the prior year quarter. Income on mezzanine funds varies from period to period based on changes in the value of underlying investments.

Exhibit 99.1

Non-interest expense increased $3.2 million, or 15.8%, to $23.2 million. Operating expense increased $3.0 million, or 15.1%, to $22.9 million.

•Compensation expense increased $756,000, or 5.1%, to $15.6 million. The increase in compensation expense was primarily due to an increase in average FTEs, annual merit increases and promotions, and incentive compensation due to outstanding production, partially offset by a lower estimated annual incentive cash bonus program accrual. Average FTEs increased 5% to 349 in the third quarter of 2023, compared to 333 in the third quarter of 2022, as a result of expanded hiring efforts that have successfully driven growth while maintaining positive operating leverage.

•FDIC insurance increased $450,000, or 195.7%, to $680,000, primarily due to an increase in the assessment rate and the assessable base.

•Data processing expense increased $234,000, or 32.5%, to $953,000, primarily due to an increase in core processing costs commensurate with loan and deposit account growth, as well as various project implementations.

•Professional fees expense increased $226,000, or 18.8%, to $1.4 million, primarily due to an increase in recruiting expense and a general increase in other professional consulting services for various projects.

•Marketing expense increased $215,000, or 39.6%, to $758,000, primarily due to an increase in business development efforts and advertising projects commensurate with our expanded sales force.

Total period-end loans and leases receivable increased $433.3 million, or 18.6%, to $2.764 billion.

•C&I loans increased $283.6 million, or 35.4% to $1.084 billion, due to growth across all products and geographies.

•CRE loans increased $150.4 million, or 10.1%, to $1.635 billion, primarily due to increases in non-owner occupied CRE and multi-family loans.

Total period-end in-market deposits grew $260.0 million, or 13.5%, to $2.189 billion, and the average rate paid increased 236 basis points to 2.97%. The increase in in-market deposits was principally due to a $317.9 million and $124.6 million increase in interest bearing transaction accounts and certificates of deposits, respectively. This increase was partially offset by a $134.1 million and $48.3 million decrease in non-interest bearing deposit accounts and money market accounts, respectively.

Period-end wholesale funding increased $246.1 million to $782.2 million.

•Wholesale deposits increased $309.4 million to $467.7 million, as the Bank utilized more wholesale deposits in lieu of FHLB advances to build excess liquidity and to match-fund fixed rate assets. The average rate paid on wholesale deposits increased 161 basis points to 4.07% and the weighted average original maturity increased to 4.0 years from 0.3 years. Consistent with our balance sheet strategy to use the most efficient and cost effective source of wholesale funding, the Company has entered into several derivative contracts hedging a portion of the wholesale deposits to reduce the fixed rate funding costs.

•FHLB advances decreased $63.3 million to $314.5 million. The average rate paid on FHLB advances increased 47 basis points to 2.48% and the weighted average original maturity increased to 5.2 years from 4.8 years.

Non-performing assets increased to $17.7 million, or 0.52% of total assets, compared to $3.8 million, or 0.13% of total assets, driven by one loan in the ABL portfolio and Equipment Finance loans within the C&I portfolio. Excluding the one ABL loan, which defaulted during the second quarter of 2023, non-performing assets totaled $8.1 million, or 0.24% of total assets.

The allowance for credit losses, including unfunded commitment reserves, increased $6.9 million to $31.0 million, compared to $24.1 million due to loan growth, an increase in specific reserves, and a change in accounting standard. The allowance for credit losses as a percent of total gross loans and leases was 1.12%, compared to the allowance for loan losses of 1.04% under the incurred loss model.

Share Repurchase Program Update

As previously announced, effective January 27, 2023, the Company’s Board of Directors authorized the repurchase by the Company of shares of its common stock with a maximum aggregate purchase price of $5.0 million, effective January 31, 2023 through January 31, 2024. As of September 30, 2023, the Company had repurchased a total of 65,112 shares for approximately $2.0 million at an average cost of $30.72 per share. The Company expects to continue its pause of the repurchase program, instead allocating capital to support continued exceptional balance sheet growth.

Investor Presentation

The Company has prepared investor presentation materials that management intends to use from time to time in discussions about the Company’s operations and performance. The presentation will be available for viewing in the Investor Relations section of the Company’s website at firstbusiness.bank and will also be furnished to the U.S. Securities and Exchange Commission on October 27, 2023.

NON-GAAP RECONCILIATIONS

Certain financial information provided in this release is determined by methods other than in accordance with generally accepted accounting principles (United States) (“GAAP”). Although the Company’s management believes that these non-GAAP financial measures provide a greater understanding of its business, these measures are not necessarily comparable to similar measures that may be presented by other companies.

TANGIBLE BOOK VALUE

“Tangible book value per share” is a non-GAAP measure representing tangible common equity divided by total common shares outstanding. “Tangible common equity” itself is a non-GAAP measure representing common stockholders’ equity reduced by intangible assets, if any. The Company’s management believes that this measure is important to many investors in the marketplace who are interested in period-to-period changes in book value per common share exclusive of changes in intangible assets. The information provided below reconciles tangible book value per share and tangible common equity to their most comparable GAAP measures.

TANGIBLE COMMON EQUITY TO TANGIBLE ASSETS

“Tangible common equity to tangible assets” (“TCE”) is defined as the ratio of common stockholders’ equity reduced by intangible assets, if any, divided by total assets reduced by intangible assets, if any. Adjusted TCE ratio is defined as TCE adjusted for net fair value adjustments of financial assets and liabilities. For more information on fair value adjustments please refer to Note 19 - Fair Value Disclosures in the annual report on Form 10-K for the year ended December 31, 2022. The Company’s management believes that this measure is important to many investors in the marketplace who are interested in the relative changes from period to period in common equity and total assets, each exclusive of changes in intangible assets. The information below reconciles tangible common equity and tangible assets to their most comparable GAAP measures.

Exhibit 99.1

EFFICIENCY RATIO & PRE-TAX, PRE-PROVISION ADJUSTED EARNINGS

“Efficiency ratio” is a non-GAAP measure representing non-interest expense excluding the effects of the SBA recourse provision, impairment of tax credit investments, losses or gains on repossessed assets, amortization of other intangible assets and other discrete items, if any, divided by operating revenue, which is equal to net interest income plus non-interest income less realized gains or losses on securities, if any. “Pre-tax, pre-provision adjusted earnings” is defined as operating revenue less operating expense. In the judgment of the Company’s management, the adjustments made to non-interest expense and non-interest income allow investors and analysts to better assess the Company’s operating expenses in relation to its core operating revenue by removing the volatility that is associated with certain one-time items and other discrete items. The information provided below reconciles the efficiency ratio and pre-tax, pre-provision adjusted earnings to its most comparable GAAP measure.

Exhibit 99.1

ADJUSTED NET INTEREST MARGIN

“Adjusted Net Interest Margin” is a non-GAAP measure representing net interest income excluding the fees in lieu of interest and other recurring, but volatile, components of net interest margin divided by average interest-earning assets less other recurring, but volatile, components of average interest-earning assets. Fees in lieu of interest are defined as prepayment fees, asset-based loan fees, non-accrual interest, and loan fee amortization. In the judgment of the Company’s management, the adjustments made to net interest income allow investors and analysts to better assess the Company’s net interest income in relation to its core client-facing loan and deposit rate changes by removing the volatility that is associated with these recurring but volatile components. The information provided below reconciles the net interest margin to its most comparable GAAP measure.
