-- Strong top line revenue and provision benefit drive tangible book value growth --

First Business Financial Services, Inc. (the “Company”, the “Bank”, or “First Business Bank”) (Nasdaq:FBIZ) reported quarterly net income available to common shareholders of $11.0 million, or $1.29 diluted earnings per share. This compares to net income of $8.7 million, or $1.02 per share, in the first quarter of 2022 and $8.2 million, or $0.95 per share, in the second quarter of 2021.

“Our record quarterly net income was driven by a notable increase in net interest income and exceptional commitment to asset quality resulting in a significant loan loss provision benefit,” President and Chief Executive Officer Corey Chambas said. “Despite above-average loan payoffs this year, we remain confident in our ability to produce 10% net loan growth. We believe this sustained loan growth and expanding net interest margin will continue to generate double-digit annual revenue growth.” Chambas added, “With an enhanced capital base, focus on diversified revenue streams, and relentless attention to credit quality, we believe we are well positioned to extend our track record of performance over the long term.”

Quarterly Highlights

• Robust Profitability Metrics. Pre-tax, pre-provision adjusted (“PTPP”) earnings, excluding Paycheck Protection Program (“PPP”) interest and fee income, increased $998,000, or 10.4%, from the linked quarter and $3.7 million, or 53.8%, from the prior year quarter. The improvement in profitability was driven by an increase in top line revenue, which rose $1.8 million, or 6.3%, from the linked quarter and $5.4 million, or 21.9%, from the prior year quarter. With revenue growth outpacing operating expense growth, the Company increased PTPP return on average assets to 1.57% in the second quarter of 2022, compared to 1.46% in linked quarter and 1.15% in the prior year quarter.

• Strong Asset Quality. The Bank continued its strong asset quality trend, highlighted by the team’s ability to proactively work through challenging loans to achieve positive outcomes for the Bank and its shareholders. Non-performing assets declined to $5.7 million, or 0.21% of total assets, improving from 0.40% of total assets on June 30, 2021. The Company recorded a provision benefit of $3.7 million, compared to a benefit of $855,000 in the first quarter of 2022 and $1.0 million in the second quarter of 2021. The provision benefit in the second quarter of 2022 was primarily due to a $4.1 million principal recovery on a legacy SBA relationship originated in May 2016 and fully charged-off in December 2020.

• Record Net Interest Income Reflecting Loan Growth and Net Interest Margin Expansion. Net interest income grew to a record $23.7 million, increasing $2.2 million, or 10.4%, from the linked quarter and $2.0 million, or 9.3%, from the prior year quarter. This increase was primarily due to a 32 and 22 basis point expansion in net interest margin compared to the linked and prior year quarters, respectively. This net interest expansion resulted from rising rates on variable-rate loans and low deposit betas on in-market deposits following the Federal Open Market Committee’s (“FOMC”) decision to raise the target Fed Funds rate 150 basis points during the first half of 2022.

• Increased Organic Loan Production. Loans, excluding net PPP loans, grew $48.9 million, or 8.8% annualized, from the first quarter of 2022 and $259.1 million, or 12.8%, from the second quarter of 2021, as the Company’s previous investments in both conventional and specialized lending continue to generate positive results.

• Compounding Tangible Book Value Growth. The Company’s demonstrated earnings power and diligent credit management more than offset the interest-rate-driven market value decline in the investment portfolio, providing a 9.4% annualized increase in tangible book value compared to the linked quarter and 9.7% compared to the prior year quarter.

Second Quarter 2022 Compared to First Quarter 2022

Net interest income increased $2.2 million, or 10.4%, to $23.7 million.

• Net interest income growth was driven by an increase in average loans and leases, net interest margin expansion, and an increase in fees in lieu of interest, which included the recovery of $709,000 in interest from a previously charged-off legacy SBA loan relationship. Average loans and leases receivable increased $37.6 million, or 6.8% annualized, to $2.261 billion. Fees in lieu of interest, which can vary from quarter to quarter based on client-driven activity, totaled $1.9 million, compared to $1.3 million, and included $196,000 and $249,000 in PPP fees, respectively. Excluding fees in lieu of interest and interest income from PPP loans, net interest income increased $1.7 million, or 8.4%.

• Net interest margin was 3.71%, up 32 basis points compared to 3.39% in the linked quarter. Adjusted net interest margin was 3.45%, up 21 basis points compared to 3.24% in the linked quarter. The primary driver of improved net interest margin was a low deposit beta and higher earning asset yields in the current rising rate environment. The change in the 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. Management defines short-term market rates as the daily average effective federal funds rate for purposes of estimating interest-earning asset and interest-bearing liability betas. 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 average net PPP loans and other recurring, but volatile, components of average interest-earning assets.

• The yield on average interest-earning assets increased 40 basis points to 4.24% from 3.84%. Excluding average net PPP loans, PPP loan interest income, and fees in lieu of interest, the yield earned on average interest-earning assets increased 30 basis points to 3.96% from 3.66%.

• The rate paid for average interest-bearing, in-market deposits increased 10 basis points to 0.29% from 0.19%. The rate paid for average total bank funding increased 15 basis points to 0.46% from 0.31%. Total bank funding is defined as total deposits plus Federal Home Loan Bank (“FHLB”) advances. The daily average effective federal funds rate increased 65 basis points compared to the linked quarter, which equates to an in-market, interest-bearing deposit beta of 15% for the three months ended June 30, 2022.

• The Bank continues to maintain an asset-sensitive balance sheet and ended the quarter appropriately positioned for net interest income to continue to benefit; however, the Bank anticipates deposit betas will rise at a greater rate with further increases in the federal funds rate during the second half of the year, slowing the pace of net interest margin expansion.

The Company reported a net benefit to provision for loan and lease losses of $3.7 million, compared to a $855,000 benefit in the first quarter of 2022.

• The provision benefit in the second quarter of 2022 was primarily due to net recoveries of $4.2 million, partially offset by a $527,000 increase in the general reserve due to loan growth.

Non-interest income decreased $514,000, or 7.0%, to $6.9 million.

• Other fee income decreased $1.2 million to $860,000, compared to $2.1 million in the first quarter. The decrease is primarily due to above-average returns on the Company’s investments in mezzanine funds in the first quarter, which returned to historical levels in the second quarter.

• Private Wealth management fee income increased $11,000, or 0.4% to $2.9 million, despite lower market values during the second quarter. Private Wealth and trust assets under management and administration measured $2.554 billion at June 30, 2022, down $280.3 million, primarily due to a decrease in market valuations, which was partially offset by new business development.

• Gains on sale of SBA loans increased $366,000 to $951,000.

• Commercial loan swap fee income increased $246,000 to $471,000. Swap fee income can vary from period to period based on loan activity and the interest rate environment.

Non-interest expense increased $633,000, or 3.4%, to $19.5 million, while operating expense increased $798,000, or 4.2%, to $19.7 million.

• Compensation expense was $14.0 million, reflecting an increase of $382,000, or 2.8%, from the linked quarter due to a $474,000 one-time increase to the annual cash incentive bonus program accrual, as well as expanded hiring to support the Bank’s growth plans. Management believes there will be upward pressure on compensation throughout the remainder of the year as the Bank continues to opportunistically invest in new talent and retain existing talent in the competitive market. Average FTEs for the second quarter of 2022 were 321, up eleven from 310 in the linked quarter as management continued to focus on talent acquisition to support the Bank’s growth initiatives.

• Marketing expense increased $170,000, or 34.0%, to $670,000 primarily due to the increase in client entertainment and sponsorships as business development activities continue to increase towards pre-pandemic levels.

• Professional fees increased $128,000, or 10.9%, to $1.3 million from the linked quarter primarily due to an increase in recruiting expense.

• Data processing expense increased $112,000, or 14.4%, to $892,000 primarily due to the recurring annual expense related to tax processing on behalf of the Bank’s Private Wealth clients.

Income tax expense increased $1.4 million, or 65.7%, to $3.6 million. The effective tax rate was 23.7% for the six months ended June 30, 2022, compared to 23.6% for the same period in 2021. For 2022, the Company expects to report an effective tax rate of approximately 23% as management intends to continue actively pursuing tax credit opportunities.

Total period-end loans and leases receivable increased $38.9 million, or 6.9% annualized, to $2.290 billion. Excluding net PPP loans, total period-end loans and leases receivable increased $48.9 million, or 8.8% annualized, to $2.282 billion.

• Commercial and industrial (“C&I”) loans increased $20.7 million, or 11.6% annualized, to $741.4 million, compared to $720.7 million. Excluding PPP loans, C&I loans increased $30.9 million, or 17.6% annualized, due to an increase in specialized lending.

• Commercial real estate (“CRE”) loans increased by $18.8 million, or 5.1% annualized, to $1.488 billion, compared to $1.470 billion. Increases in construction financing, owner-occupied CRE, multi-family, and land development were offset by a decrease in non-owner occupied CRE loans.

Total period-end in-market deposits decreased $154.4 million, or 30.7% annualized, to $1.857 billion, compared to $2.011 billion. The average rate paid was 0.20%, up seven basis points from 0.13% in the first quarter. The decline in balances was due to movement of client deposits to investment alternatives, seasonality within the Bank’s municipality clients, tax payments, and normal course of business for continuing client relationships.

”On the deposit front, the second quarter is typically seasonally weaker, due to tax payments and other business cycle reasons – just as the first quarter was seasonally strong,” said Corey Chambas. “What was unusual this quarter was several clients moved large amounts of deposits into investments and there were some large client distributions to investors, as well. Importantly, we have not lost any meaningful client relationships associated with these decreases in deposits. We believe a better measure of our deposit picture is that average deposits are up 10% from a year ago, and due to our Treasury Management sales success, service charge fee income is up 11% from a year ago.”

Period-end wholesale funding, including FHLB advances, brokered deposits, and deposits gathered through internet deposit listing services, increased $192.7 million to $566.4 million.

• Wholesale deposits were $12.3 million in both periods. The average rate paid on wholesale deposits increased seven basis points to 2.98% and the weighted average original maturity was 4.8 years.

• FHLB advances increased $192.7 million to $554.1 million. The average rate paid on FHLB advances increased 40 basis points to 1.48% and the weighted average original maturity decreased to 3.2 years from 6.0 years.

Non-performing assets were $5.7 million, or 0.21% of total assets, in both periods of comparison.

The allowance for loan and lease losses increased $435,000, or 1.8%, as an increase in the general reserve from loan growth was partially offset by a decrease in general reserve driven by a change in qualitative risk factors.

• The allowance for loan and lease losses as a percent of total gross loans and leases was 1.05% in both periods of comparison (1.06% excluding net PPP loans).

Second Quarter 2022 Compared to Second Quarter 2021

Net interest income increased $2.0 million, or 9.3%, to $23.7 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. Fees in lieu of interest decreased from $3.5 million to $1.9 million, primarily due to a $2.3 million reduction in PPP loan fee amortization. Excluding fees in lieu of interest and interest income from PPP loans, net interest income increased $4.2 million, or 24.0%. Excluding net PPP loans, average gross loans and leases increased $267.1 million, or 13.4%.

• Net interest margin increased 22 basis points to 3.71% from 3.49%. Adjusted net interest margin increased 25 basis points to 3.45% from 3.20%.

• The yield on average interest-earning assets measured 4.24% compared to 3.96%. Excluding fees in lieu of interest, PPP loan interest income, and net PPP loans, the yield on average interest-earning assets measured 3.96%, compared to 3.64%. 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 rate paid for average interest-bearing in-market deposits increased eight basis points to 0.29% from 0.21%. The rate paid for average total bank funding increased seven basis points to 0.46% from 0.39%.

The Company reported a net benefit to provision for loan and lease losses of $3.7 million, compared to provision benefit of $958,000 in the second quarter of 2021. The reasons for the provision benefit are consistent with the explanations discussed above in the linked quarter comparison.

Non-interest income of $6.9 million increased by $551,000, or 8.7%, from $6.3 million in the prior year period.

• Private Wealth management fee income increased $108,000, or 3.9%, to $2.9 million, despite a decline in market values, due to the addition of new money from existing clients. Private Wealth and trust assets under management and administration measured $2.554 billion at June 30, 2022, down $10.6 million, or 0.4%.

• Gains on sale of SBA loans decreased $252,000 to $951,000.

• Loan fees of $697,000 increased by $128,000, or 22.5%, primarily due to an increase in conventional, SBA, and Floorplan Financing activity generating additional service fee income.

• Commercial loan swap fee income was $471,000. There was no swap fee activity in the prior year quarter. Swap fee income varies from period to period based on loan activity and the interest rate environment in any given quarter.

• Service charges on deposits increased $100,000, or 10.6%, to $1.0 million compared to $941,000, due to an increase in existing and new deposit client relationships.

Non-interest expense increased $1.3 million, or 7.0%, to $19.5 million. Operating expense increased $1.8 million, or 9.8%, to $19.7 million.

• Compensation expense increased $765,000, or 5.8%, to $14.0 million. Average FTEs were 321 in the second quarter of 2022, compared to 312 in the second quarter of 2021. The reasons for the increase in compensation expense are consistent with the explanations discussed above in the linked quarter analysis.

• Professional fees increased $385,000, or 42.2%, to $1.3 million, primarily due to an increase in recruiting expense, audit expenses, and a general increase in other professional consulting services for various projects.

• Marketing expense increased $159,000, or 31.1%, to $670,000 mainly due to an increase in business development activities as the Company continues to return to pre-pandemic spending levels.

Total period-end loans and leases receivable increased $146.5 million, or 6.8%, to $2.290 billion. Excluding net PPP loans, total period-end loans and leases receivable increased $259.1 million, or 12.8%, to $2.282 billion.

• C&I loans increased $45.9 million, or 6.6% to $741.4 million. Excluding PPP loans, C&I loans increased $161.5 million, or 28.2%, to $733.1 million due to an increase in conventional and specialized Commercial Lending. Management believes this growth rate will moderate to lower double-digits as the Company’s specialized lending products scale over time.

• CRE loans increased $96.5 million, or 6.9%, primarily due to an increase in non-owner-occupied real estate and construction financing.

Total period-end in-market deposits decreased $159.2 million, or 7.9%, to $1.857 billion and the average rate paid increased five basis points to 0.20%. This decrease in deposits was principally due to a $274.7 million decrease in transaction accounts, partially offset by a $68.9 million and $46.6 million increase in certificates of deposit and money market accounts, respectively. The reasons for the decrease in deposits are consistent with the explanations discussed above in the linked quarter comparison.

Period-end wholesale funding increased $34.1 million to $566.4 million.

• Wholesale deposits decreased $132.2 million to $12.3 million, compared to $144.5 million, as the existing portfolio runoff was replaced by FHLB advances. The average rate paid on brokered certificates of deposit increased 224 basis points to 2.98% and the weighted average original maturity increased to 4.8 years from 3.5 years.

• FHLB advances increased $166.3 million to $554.1 million. The average rate paid on FHLB advances increased 21 basis points to 1.48% and the weighted average original maturity decreased to 3.2 years from 6.1 years.

Non-performing assets decreased to $5.7 million, or 0.21% of total assets, compared to $11.6 million, or 0.40% of total assets. Excluding net PPP loans, non-performing assets decreased to 0.21% of total assets compared to 0.42%.

The allowance for loan and lease losses decreased $1.6 million to $24.1 million, compared to $25.7 million.

• The allowance for loan and lease losses as a percent of total gross loans and leases was 1.05% compared to 1.20%.

• Excluding net PPP loans, the allowance for loan and leases losses as a percent of total gross loans and leases was 1.06% compared to 1.27%.

Paycheck Protection Program

As of June 30, 2022, the Company had $8.3 million in gross PPP loans outstanding and deferred processing fees outstanding of $113,000. The processing fees are deferred and recognized over the contractual life of the loan, or accelerated at forgiveness, as an adjustment of yield using the interest method. During the three months ended June 30, 2022, the Company recognized $196,000 of PPP processing fees in interest income. The SBA provides a guaranty to the lender of 100% of principal and interest, unless the lender violated an obligation under the agreement.
