Top Line Revenue

Top line revenue, comprised of net interest income and non-interest income, increased $5.7 million, or 13.8%, for the three months ended June 30, 2026, compared to the same period in 2025, due to a 12.9% increase in net interest income and an 18.1% increase in non-interest income. The increase in net interest income was primarily driven by increases in average loans and leases outstanding and prepayment fees, partially offset by lower short-term market rates. The increase in non-interest income was due pri

These strategies are described below:

•
We will protect and strengthen our unique culture with a growing and geographically diverse team.

•
We will develop future-ready talent who will thrive in the workplace of the future by continuously investing in our team to elevate their impact and contribution.

•
We will grow our core deposits by driving a company-wide commitment to adding new relationships and capitalizing on innovative sources and new technologies.

Results of Operations

Top Line Revenue

42

Table of Contents

Top line revenue, comprised of net interest income and non-interest income, increased $15.2 million, or 9.9%, for the year ended December 31, 2025, compared to the year ended December 31, 2024, due to a 10.1% increase in net interest income and a 9.2% increase in non-interest income. The increase in net interest income was driven by an increase in average gross loans and leases partially offset by net interest margin compression. The increase in non-interest income was due to increases in private wealth fee income, bank owned life insurance policy income, service charges on deposits, and commercial loan swap fee income, partially offset by a decrease in loan fees driven by a reclassification of certain items to net interest income.

The components of top line revenue were as follows:

Return on Average Assets and Return on Average Tangible Common Equity

ROAA was 1.24% for the year ended December 31, 2025, compared to 1.20% for the year ended December 31, 2024. The increase in ROAA was due to the increase in net interest income and non-interest income, partially offset by an increase in operating expenses and a higher effective tax rate. We consider ROAA a critical metric to measure the profitability of our organization and how efficiently our assets are deployed. ROAA also allows us to better benchmark our profitability to our peers without the need to consider different degrees of leverage which can ultimately influence return on equity measures.

ROATCE for the year ended December 31, 2025 was 15.25%, compared to 15.35% for the year ended December 31, 2024. We view ROATCE as an important measurement for monitoring profitability and continue to focus on improving our return to our shareholders by enhancing the overall profitability of our client relationships, controlling our expenses, and minimizing our costs of credit.

Efficiency Ratio and Pre-Tax, Pre-Provision Adjusted Earnings

Efficiency ratio measured 58.78% for the year ended December 31, 2025, compared to 60.61% for the year ended December 31, 2024. Efficiency ratio is a non-GAAP measure representing operating expense divided by operating revenue. Operating expense is defined as non-interest expense excluding the effects of the SBA recourse benefit or provision, impairment of tax credit investments, net gains or losses on repossessed assets, amortization of other intangible assets, and other discrete items, if any. Operating revenue is defined as net interest income plus non-interest income less realized net gains or losses on securities, if any, and other discrete items.

PTPP adjusted earnings for the year ended December 31, 2025, was $69.4 million, increasing 14.8%, compared to $60.4 million for the year ended December 31, 2024. PTPP adjusted earnings is a non-GAAP measure defined as operating revenue less operating expense. In the judgment of the Corporation’s management, the adjustments made to non-interest expense and non-interest income allow investors and analysts to better assess the Corporation’s operating expenses in relation to its core operating revenue by removing the volatility associated with certain one-time items and other discrete items. PTPP adjusted earnings allows management to benchmark performance of our model to our peers without the influence of the loan loss provision and tax considerations, which will ultimately influence other traditional financial measurements, including ROA and ROATCE. The information provided below reconciles the efficiency ratio and PTPP adjusted earnings to their most comparable GAAP measure.

Table of Contents

Please refer to the Non-Interest Income and Non-Interest Expense sections below for discussion on additional drivers of the year-over-year change in the efficiency ratio and PTPP adjusted earnings.

Net Interest Income

Net interest income levels depend on the amount of and yield on interest-earning assets as compared to the amount of and rate paid on interest-bearing liabilities. Net interest income is sensitive to changes in market rates of interest and the asset/liability management processes to prepare for and respond to such changes.

The change in yield of the respective interest-earning assets 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 table below displays the beta calculations for loans and leases, total interest earning assets, core deposits, interest-bearing deposits and total interest-bearing liabilities for the year ended December 31, 2025, and 2024.

Total bank funding represents total deposits plus FHLB advances.

Net interest income increased $12.5 million, or 10.1% during the year ended December 31, 2025, compared to the year ended December 31, 2024. The increase in net interest income reflected an increase in average gross loans and leases, the reclassification of certain types of C&I loan fees from non-interest income to interest income, and lower cost of interest-bearing liabilities due to decreases in interest rates. These changes were partially offset by a decrease in yield on loans, non-accrual interest reversals, and a decrease in asset-based loan fees. Average gross loans and leases of $3.272 billion increased by $275.0 million, or 9.2%, for the year ended December 31, 2025, compared to $2.997 billion for the same period in 2024.

The yield on average interest-earning assets for the year ended December 31, 2025, was 6.59%, compared to 6.87% for the year ended December 31, 2024. The decrease in yield was primarily due to lower interest rates, partially offset by the reinvestment of cash flows from the securities and fixed-rate loan portfolios.

The average rate paid on total interest-bearing liabilities was 3.51% for the year ended December 31, 2025, a decrease from 3.91% for the year ended December 31, 2024. Total interest-bearing liabilities includes interest-bearing deposits, FHLB advances, subordinated and junior subordinated notes and debentures payable, federal funds purchased, and other borrowings. The average rates paid decreased due to lower short-term interest rates, the replacement of maturing wholesale funds at higher fixed rates, and client movement from non-interest bearing to interest bearing core deposit products.

Net interest margin decreased to 3.64% for the year ended December 31, 2025, compared to 3.66% for the year ended December 31, 2024. The decrease in net interest margin was due to lower yields on interest-earning assets, partially offset by lower costs of interest-bearing liabilities due to lower interest rates and the reclassification of certain types of C&I loan fees from non-interest income to net interest income.

The Corporation maintains a target for net interest margin in the range of 3.60% to 3.65%. Performance in future periods will vary due to factors such as the level of fees in lieu of interest and the timing, pace, and scale of future interest rate changes.

Provision for Credit Losses

We determine our provision for credit losses pursuant to our allowance for credit loss methodology. It is based on a reasonable and supportable forecast as well as considerations for composition, risk, and performance indicators in our credit portfolio. Refer to Allowance for Credit Losses in the Critical Accounting Policy section, for further information regarding our allowance for credit loss methodology.

The following table shows the components of the provision for credit losses.

Non-Interest Income

Non-interest income increased by $2.7 million, or 9.2%, to $31.9 million for the year ended December 31, 2025, from $29.3 million for the year ended December 31, 2024. Management continues to focus on revenue growth from multiple non-interest income sources to maintain a diversified revenue stream through greater contributions from fee-based revenues. Total non-interest income accounted for 18.9% of total revenues for the year ended December 31, 2025, compared to 19.1% in 2024 as net interest income increased at a greater rate than non-interest income. The increase in total non-interest income for the year ended December 31, 2025, was driven by private wealth fee income, bank-owned life insurance policy income, commercial loan swap fee income, and service charges on deposits, partially offset by a reduction in loan fees driven by the reclassification of certain types of C&I fees from non-interest income to net interest income.

The components of non-interest income were as follows:

(1)
Fee income ratio is fee income, per the above table, divided by top line revenue (defined as net interest income plus non-interest income).

Table of Contents

Private wealth fee income increased $1.5 million, or 11.0%, for the year ended December 31, 2025, compared to the year ended December 31, 2024. Private wealth fee income increased compared to the prior year primarily due to an increase in assets under management and administration and increases in fee rates across the client base. Private wealth fee income can vary due to the mix of business at different fee structures and can be positively or negatively influenced by the timing and magnitude of volatility within the capital markets. As of December 31, 2025, private wealth and trust assets under management and administration totaled $3.815 billion, increasing $396.0 million, or 11.6%, compared to $3.419 billion as of December 31, 2024, due to an increase in market values, new clients, and new money from existing clients.

Bank-owned life insurance policy income increased $1.1 million, or 67.1%, for the year ended December 31, 2025, compared to the year ended December 31, 2024. The increase is primarily due to the purchase of new policies, totaling $24.5 million in the second quarter of 2025 and an insurance claim of $234,000 in the third quarter of 2025.

Service charges on deposits increased $720,000, or 19.1%, for the year ended December 31, 2025, compared to the year ended December 31, 2024. The increase is primarily driven by new and expanded core deposit relationships and a reduction in earnings credit rates. Treasury management business development efforts remain robust as gross treasury management service charges increased $473,000, or 7.3%, for the year ended December 31, 2025, compared to the year ended December 31, 2024. Management believes growth in gross analyzed service charges is a strong indicator of success for the Corporation given the direct correlation to adding and expanding core business relationships.

Commercial loan interest rate swap fee income increased $592,000, or 42.2%, for the year ended December 31, 2025, compared to the year ended December 31, 2024. We originate commercial real estate loans in which we offer clients a floating rate and an interest rate swap. The client’s swap is then offset with a counter-party dealer. The execution of these transactions generates swap fee income. Interest rate swaps can be an attractive product for our commercial borrowers, although associated fee income varies from period to period based on loan activity, the interest rate environment, and the duration of the swap contracts.

Other non-interest income increased $541,000, or 14.1%, for the year ended December 31, 2025, compared to the year ended December 31, 2024. The increase was primarily due to nonrecurring fee income in accounts receivable financing and increases in credit card fee income, bank consulting fee income, and other equipment finance related fees. These increases were partially offset by a decrease in limited partnership investment income.

Loan fee income decreased $1.7 million, or 49.3%, for the year ended December 31, 2025 compared to the year ended December 31, 2024. The change is primarily due to the reclassification of certain types of C&I loan fees from non-interest income to interest income. Excluding this reclassification, loan fee income increased $113,000, or 7.0%. The change excluding the reclassification is primarily due to an increase in traditional commercial loan fees.

Non-Interest Expense

Non-interest expense increased by $6.0 million, or 6.5%, for the year ended December 31, 2025, compared to the year ended December 31, 2024. Operating expense, which excludes certain one-time and discrete items as defined in the Efficiency Ratio table above, increased $6.0 million, or 6.4%, for the year ended December 31, 2025, compared to the year ended December 31, 2024.

The components of non-interest expense were as follows:

(1)
Total operating expense represents total non-interest expense, adjusted to exclude the impact of discrete items as previously defined in the non-GAAP efficiency ratio calculation, above.

Compensation expense increased by $4.8 million, or 7.6%, for the year ended December 31, 2025, compared to the year ended December 31, 2024, principally due to an increase in average FTEs, salary increases, growth in employee benefit costs, and increase in the annual cash bonus accrual. The increase reflects a $2.5 million, or 6.2%, increase in employee salaries and a $1.1 million, or 18.4%, increase in estimated annual cash bonuses compared to 2024. Average FTEs of 363 for the year ended December 31, 2025, increased by 13, or 3.7%, from 350 for the year ended December 31, 2024.

Computer software expense increased $821,000, or 13.3%, for the year ended December 31, 2025, compared to the year ended December 31, 2024. The increase was primarily due to our commitment to innovative technology to support growth initiatives, enhance productivity and security, and improve the client experience.

FDIC insurance increased $471,000, or 17.1%, for the year ended December 31, 2025, compared to the year ended December 31, 2024. The increase was commensurate with the increase in total assets, brokered deposits, and non-accrual loans.

Other non-interest expense increased $468,000, or 12.7%, for the year ended December 31, 2025, compared to the year ended December 31, 2024. The increase was primarily due to an increase in liquidation expenses and a release of SBA recourse reserve in the prior year period.

Marketing expense increased $326,000, or 9.3%, for the year ended December 31, 2025, compared to the year ended December 31, 2024. The increase was primarily due to an increase in business development efforts and advertising projects related to the Company’s growth initiatives.

Professional fees decreased $653,000, or 11.5%, for the year ended December 31, 2025, compared to the year ended December 31, 2024. The decrease was primarily due to a decrease in recruiting expense and professional consulting services for various projects.

Income Taxes

Income tax expense totaled $10.1 million for the year ended December 31, 2025, compared to $6.9 million for the year ended December 31, 2024. Income tax expense included a $1.6 million net benefit from tax credit investments for the years ended December 31, 2025 and 2024. The effective tax rate for the year ended December 31, 2025, was 16.8% compared to 13.5% for the year ended December 31, 2024. The year-over-year increase was mainly driven by a $1.7 million partial release of a state deferred tax asset valuation allowance in 2024, resulting from updated projections of taxable income at the state level. The Corporation expects to report an effective tax rate between 16% and 18% for 2026.

Financial Condition

General

Total assets increased by $228.7 million, or 5.9%, to $4.082 billion as of December 31, 2025, compared to $3.853 billion at December 31, 2024. The increase in total assets was primarily driven by an increase in loans and leases receivable and available-for-sale securities, partially offset by a reduction in short-term investments. Total liabilities increased by $185.7 million, or 5.3%, to $3.710 billion at December 31, 2025, compared to $3.525 billion at December 31, 2024. The increase in total liabilities was principally due to an increase in deposits, partially offset by a decrease in Federal Home Loan Bank borrowings.

Cash and Cash Equivalents

Cash and cash equivalents include short-term investments and cash and due from banks. Cash and due from banks increased $1.3 million to $30.8 million at December 31, 2025, from $29.5 million at December 31, 2024. Short-term investments decreased by $119.5 million to $8.7 million at December 31, 2025, from $128.2 million at December 31, 2024. Our short-term investments primarily consist of interest-bearing deposits held at the Federal Reserve Bank ("FRB"). We value the safety and soundness provided by the FRB, and therefore, we incorporate short-term investments in our readily accessible liquidity program. As of December 31, 2025, and December 31, 2024, interest-bearing deposits held at the FRB were $7.7 million and $127.8 million, respectively. In general, the level of our cash and short-term investments will be influenced by the timing of deposit gathering, scheduled maturities of wholesale deposits, funding of loan and lease growth when opportunities are presented, and the level of our securities portfolio. Please refer to the section entitled Liquidity and Capital Resources for further discussion.

Securities

Total securities, including available-for-sale and held-to-maturity, increased by $79.2 million, or 22.7%, to $427.3 million, or 10.5% of total assets at December 31, 2025, compared to $348.1 million or 9.0% of total assets at December 31, 2024. As of December 31, 2025, and 2024, our total securities portfolio had a weighted average estimated remaining maturity of approximately 4.7 years and 5.2 years, respectively. The investment portfolio primarily consists of mortgage-backed securities and is used to provide a source of liquidity, including the ability to pledge securities for possible future cash advances, while contributing to the earnings potential of the Bank. The overall duration of the securities portfolio is established and maintained to further mitigate interest rate risk present within our balance sheet as identified through asset/liability simulations. We purchase investment securities intended to protect net interest margin while maintaining an acceptable risk profile. In addition, we will purchase investment securities to utilize our cash position effectively within appropriate policy guidelines and estimates of future cash demands. While mortgage-backed securities present prepayment risk and extension risk, we believe the overall credit risk associated with these investments is minimal, as all of the securities we hold are guaranteed by the United States Treasury, the Federal National Mortgage Association (“FNMA”), the Federal Home Loan Mortgage Corporation (“FHLMC”), or the Government National Mortgage Association (“GNMA”), a U.S. government agency. The estimated repayment streams associated with this portfolio also allow us to better match short-term liabilities. The Bank’s investment policies allow for various types of investments, including tax-exempt municipal securities. The ability to invest in tax-exempt municipal securities provides for further opportunity to improve our overall yield on the securities portfolio. We evaluate the credit risk of the municipal securities prior to purchase and generally limit exposure to general obligation issuances from municipalities, primarily in Wisconsin.

The majority of the securities we hold have active trading markets; therefore, we have not experienced difficulties in pricing our securities. We use a third-party pricing service as our primary source of market prices for the securities portfolio. On a quarterly basis, we validate the reasonableness of prices received from this source through independent verification of the portfolio, data integrity

51

Table of Contents

validation through comparison of current price to prior period prices, and an expectation-based analysis of movement in prices based upon the changes in the related yield curves and other market factors. On a periodic basis, we review the third-party pricing vendor’s methodology for pricing relevant securities and the results of its internal control assessments. Our securities portfolio is sensitive to fluctuations in the interest rate environment and has limited sensitivity to credit risk due to the nature of the issuers and guarantors of the securities as previously discussed. If interest rates decline and the credit quality of the securities remains constant or improves, the fair value of our debt securities portfolio would likely improve, thereby increasing total comprehensive income. If interest rates increase and the credit quality of the securities remains constant or deteriorates, the fair value of our debt securities portfolio would likely decline and therefore decrease total comprehensive income. The magnitude of the fair value change will be based upon the duration of the portfolio. A securities portfolio with a longer average duration will exhibit greater market price volatility than a securities portfolio with a shorter average duration in a changing rate environment. During the year ended December 31, 2025, we recognized unrealized holding gains of $11.6 million before income taxes through other comprehensive income. These gains were primarily the result of a decrease in market interest rates. No securities within our portfolio were deemed to require an allowance for credit losses as of December 31, 2025. We sold no securities during the year ended December 31, 2025. As of December 31, 2025, no securities were classified as trading securities. At December 31, 2025, $38.8 million of our securities were pledged to secure various obligations, including interest rate swap contracts and municipal deposits.

The tables below set forth information regarding the amortized cost and fair values of our securities.

U.S. Treasuries represent treasury bonds issued by the United States Treasury. U.S. government agency securities - government-sponsored enterprises represent securities issued by FNMA. Municipal securities include securities issued by various municipalities located primarily within Wisconsin and are primarily general obligation bonds that are tax-exempt in nature. Residential and

commercial mortgage-backed securities - government issued represent securities guaranteed by GNMA. Residential and commercial mortgage-backed securities - government-sponsored enterprises include securities guaranteed by FHLMC, FNMA, and the FHLB.

The following table sets forth the contractual maturity and weighted average yield characteristics of the fair value of our available-for-sale securities and the amortized cost of our held-to-maturity securities at December 31, 2025, classified by remaining contractual maturity. Actual maturities may differ from contractual maturities because issuers have the right to call or prepay securities without call or prepayment penalties. Yields on tax-exempt securities have not been computed on a tax equivalent basis.

Investments in Limited Partnerships

The Corporation has invested in a number of limited partnerships that provide income tax, financial, and regulatory benefits due to the nature of the partnerships. These investments included: seven Small Business Investment Companies ("SBIC") and four other limited partnership investments, whose purpose is to provide funding to small companies which meet certain criteria based on each particular fund's focus, five Historic Rehabilitation Tax Credit funds ("HTC"), whose purpose is to develop and operate real estate projects related to historical properties and communities, and 12 Low-Income Housing Tax Credits ("LIHTC") projects, whose purpose is to invest in approved low-income housing investment tax credit projects.

These investments are unconsolidated variable interest entities ("VIE") because we are not considered the primary beneficiary. We have determined that we are not the primary beneficiary of these VIEs because we do not have the power to direct the activities that most significantly impact their economic performance.

53

Table of Contents

All of our limited partnership investments are privately held and their market values are not readily available. These investments are accounted for using the equity method of accounting for SBIC, other limited partnerships, and HTC funds and the proportional amortization method for LIHTC investments and are included in Other Assets in the Consolidated Balance Sheets. Income from the SBIC and other limited partnerships are included in Other Non-interest Income in the Consolidated Statements of Income and totaled $1.2 million, $1.9 million, and $5.1 million for the years ended December 31, 2025, 2024, and 2023, respectively. Income or loss from the HTC and LIHTC investments is included in income tax expense. Income from investments in limited partnerships varies from period to period based on timing of new investments and investment performance.

Derivatives

The Board approved Bank policies allow the Bank to participate in hedging strategies or to use financial futures, options, forward commitments, or interest rate swaps. The Bank periodically utilizes derivative instruments in the course of its asset/liability management. The Corporation’s derivative financial instruments, under which the Corporation is required to either receive cash from or pay cash to counterparties depending on changes in interest rates applied to notional amounts, are carried at fair value on the consolidated balance sheets.

As of December 31, 2025, the aggregate amortizing notional value of interest rate swaps with various commercial borrowers was approximately $1.167 billion, compared to $1.022 billion as of December 31, 2024. We receive fixed rates and pay floating rates based upon designated benchmark interest rates on the swaps with commercial borrowers. These swaps mature between June 2026 and July 2041. Commercial borrower swaps are completed independently with each borrower and are not subject to master netting arrangements. As of December 31, 2025, the commercial borrower swaps were reported on the Consolidated Balance Sheets as a derivative asset of $9.7 million and liability of $34.6 million compared to a derivative asset of $2.0 million and liability of $56.6 million as of December 31, 2024. Relating to the offsetting swap contracts with dealer counterparties, we pay fixed rates and receive floating rates based upon designated benchmark interest rates. These interest rate swaps also have maturity dates between June 2026 and July 2041. Dealer counterparty swaps are subject to master netting agreements among the contracts within our Bank and were reported on the Consolidated Balance Sheets as a net derivative asset of $24.9 million as of December 31, 2025, compared to a net derivative asset of $54.5 million as of December 31, 2024. In both periods, the counterparties pledged U.S. Treasuries to fully collateralize the position. The gross amount of dealer counterparty swaps as of December 31, 2025, without regard to the enforceable master netting agreement, was a gross derivative liability of $9.7 million and gross derivative asset of $34.6 million, compared to a gross derivative liability of $2.0 million and gross derivative asset of $56.6 million as of December 31, 2024.

The Corporation also enters into interest rate swaps to manage interest rate risk and reduce the cost of match-funding certain long-term fixed rate loans. These derivative contracts involve the receipt of floating rate interest from a counterparty in exchange for the Corporation making fixed-rate payments over the life of the agreement, without the exchange of the underlying notional value. The instruments are designated as cash flow hedges as the receipt of floating rate interest from the counterparty is used to manage interest rate risk associated with forecasted interest payments on short-term FHLB advances or wholesale deposits. The change in the fair value of these hedging instruments is recorded in accumulated other comprehensive income and is subsequently reclassified into earnings in the period that the hedged transactions affect earnings. As of December 31, 2025, the aggregate notional value of interest rate swaps designated as cash flow hedges was $497.5 million. These interest rate swaps mature between January 2026 and February 2041. A pre-tax unrealized loss of $8.9 million was recognized in other comprehensive income for the year ended December 31, 2025, respectively, and there was no ineffective portion of these hedges.

The Corporation also enters into interest rate swaps to mitigate market value volatility on certain long-term fixed securities. The objective of the hedge is to protect the Corporation against changes in fair value due to changes in benchmark interest rates. The instruments are designated as fair value hedges as the changes in the fair value of the interest rate swap are expected to offset changes in the fair value of the hedged item attributable to changes in the SOFR swap rate, the designated benchmark interest rate. These derivative contracts involve the receipt of floating rate interest from a counterparty in exchange for the Corporation making fixed-rate payments over the life of the agreement, without the exchange of the underlying notional value. The change in the fair value of these hedging instruments is recorded in accumulated other comprehensive income and is subsequently reclassified into earnings in the period that the hedged transactions affect earnings. As of December 31, 2025, the aggregate notional value of interest rate swaps designated as fair value hedges was $12.5 million. These interest rate swaps mature between February 2031 and October 2034. A

pre-tax unrealized loss of $175,000 was recognized in other comprehensive income for the year ended December 31, 2025, and there was no ineffective portion of these hedges.

Loans and Leases Receivable

Period-end loans and leases receivable, net of allowance for credit losses, increased by $260.0 million, or 8.4%, to $3.337 billion at December 31, 2025, from $3.077 billion at December 31, 2024.

There continues to be a concentration in CRE loans which represented 61.0% and 61.6% of our total loans, as of December 31, 2025, and December 31, 2024, respectively. Our CRE portfolio increased $143.1 million, or 7.5%, to $2.060 billion at December 31, 2025, from $1.917 billion at December 31, 2024. As of December 31, 2025, approximately 14.3% of the CRE loans were owner-occupied CRE, compared to 14.3% as of December 31, 2024. We consider owner-occupied CRE more characteristic of the Corporation's C&I portfolio as, in general, the client's primary source of repayment is the cash flow from the operating entity occupying the commercial real estate property. The increase in CRE loans was due to growth across most products in our Wisconsin and Kansas City markets.

Our C&I portfolio increased $122.3 million, or 10.6%, to $1.274 billion at December 31, 2025, from $1.152 billion at December 31, 2024. The Corporation experienced C&I loan growth in 2025, due to growth across most products and geographies. Management believes the investment in the Corporation’s C&I product lines has positioned the Corporation for strong and sustainable growth in 2026 and beyond.

We continue to actively pursue C&I loans across the Corporation as this segment of our loan and lease portfolio provides an attractive yield commensurate with an appropriate level of credit risk and creates opportunities for core deposit, treasury management, and private wealth management relationships which generate additional fee revenue. Underwriting of new credit is primarily through approval from a serial sign-off or committee process and is a key component of our operating philosophy. Business development officers have no individual lending authority limits, and thus, a significant portion of our new credit extensions require approval from a loan approval committee regardless of the type of loan or lease, or the related complexities of each proposal. To monitor the ongoing credit quality of our loans and leases, each credit is evaluated for proper risk rating using a nine grade risk rating system at the time of origination, subsequent renewal, evaluation of updated financial information from our borrowers, or as other circumstances dictate.

While we continue to experience competition from banks operating in our primary geographic areas, we remain committed to our underwriting standards and will not deviate from those standards for the sole purpose of growing our loan and lease portfolio. We expect our new loan and lease activity to allow us to continue growing in future years.

The following table presents information concerning the composition of the Bank’s consolidated loans and leases receivable.

Below is a view of selected loan portfolios disaggregated by North American Industry Classification (“NAICs”) code as of December 31, 2025:

Includes approximately $287.3 million of office real estate, or 8.5% of gross loans.

See Asset Quality for further discussion of industry-specific risks.

The following table shows the scheduled contractual maturities of the Bank’s consolidated gross loans and leases receivable, as well as the dollar amount of such loans and leases which are scheduled to mature after one year and have fixed or adjustable interest rates, as of December 31, 2025.

Commercial Real Estate. The Bank originates owner-occupied and non-owner-occupied commercial real estate loans which have fixed or adjustable rates and generally terms of three to 12 years and amortization of up to 30 years on existing commercial real estate. The Bank also originates loans to construct commercial properties and complete land development projects. The Bank’s construction loans generally have terms of six to 24 months with fixed or adjustable interest rates and fees that are due at the time of origination. Loan proceeds are disbursed in increments as construction progresses and as project inspections warrant.

Commercial and Industrial. The Bank’s commercial and industrial loan portfolio is comprised of loans for a variety of purposes which principally are secured by inventory, accounts receivable, equipment, machinery, and other corporate assets and are advanced within limits prescribed by our loan policy. The majority of such loans are secured and typically backed by personal guarantees of the owners of the borrowing business. Of the $1.274 billion of C&I loans outstanding as of December 31, 2025, $604.0 million were conventional C&I loans and $670.0 million were originated by the FBSF subsidiary. FBSF products consists of equipment financing, asset-based lending, accounts receivable financing, and floorplan financing.

Consumer and Other. The Bank originates a small amount of consumer loans consisting of home equity, first and second mortgages, and other personal loans for professional and executive clients of the Bank.

Asset Quality

Our total non-performing assets consisted of the following:

Non-accrual loans and leases increased $15.5 million, to $43.9 million at December 31, 2025, compared to $28.4 million at December 31, 2024. The Corporation's non-accrual loans and leases as a percentage of total gross loans and leases measured 1.30% and 0.91% at December 31, 2025, and 2024, respectively. The increase in non-accrual loans and leases is primarily driven by a downgrade of $20.4 million of CRE loans from a single client relationship and a new non-accrual in accounts receivable financing, partially offset by a payoff of a large C&I loan from the prior year and lower non-accrual loans in equipment financing.

We use a wide variety of available metrics to assess the overall asset quality of the portfolio and no one metric is used independently to determine the asset quality. Non-performing assets as a percentage of total assets was 1.07% and 0.74% at December 31, 2025, and December 31, 2024, respectively. As of December 31, 2025, and December 31, 2024, the payment performance of our loans and leases did not point to any new areas of concern, as approximately 98.7% and 99.1%, respectively, of the total portfolio at the end of each period was in a current payment status.

We reviewed loans and leases with exposure to certain industries:

•
Transportation and Logistics, Equipment Finance: $23 million or less than 1% of total loans - Management considered the following: 10% of Equipment Finance Transportation loans are rated Category IV. Due to our experience and forecast of continued sector stress, we are not currently originating new loans to this borrower profile in this lending niche. Based on our reserve methodology for individually and collectively evaluated loans, we believe our reserves related to this industry to be appropriate.

57

Table of Contents

•
Transportation and Logistics, other than Equipment Finance: $46 million or 1% of total loans - Management considered the following: One borrower with a balance of $6.0 million, or 13%, of the loan balance in this category is rated Category IV. Collateral on these loans includes commercial real estate, business assets, and equipment. Based on our reserve methodology for individually and collectively evaluated loans, we believe our reserves related to this industry to be appropriate.

•
Office, Commercial Real Estate: $287 million or 9% of total loans - Management considered the following: office exposure is concentrated in the Wisconsin markets where local market vacancy rates are below national rates and none of the loans in this category are rated Category IV. Based on our reserve methodology for individually and collectively evaluated loans, we believe our reserves related to this loan category to be appropriate.

•
Multifamily, Commercial Real Estate: $571 million or 17% of total loans - Management considered the following: one borrower with a balance of $4.3 million, or 1% of the loan balance in this category is rated Category IV, multifamily exposure is concentrated in the Wisconsin markets where local market vacancy rates are below national rates. Based on our reserve methodology for individually and collectively evaluated loans, we believe our reserves related to this loan category to be appropriate.

We also monitor asset quality through our established categories as defined in Note 4 – Loans, Lease Receivables, and Allowance for Credit Losses of the Consolidated Financial Statements. As we continue to actively monitor the credit quality of our loan and lease portfolios, we may identify additional loans and leases for which the borrowers or lessees are having difficulties making the required principal and interest payments based upon factors including, but not limited to, the inability to sell the underlying collateral, inadequate cash flow from the operations of the underlying businesses, liquidation events, or bankruptcy filings. We proactively work with our loan borrowers experiencing financial difficulty to find meaningful solutions to difficult situations that are in the best interests of the Bank.

The following represents additional information regarding our non-accrual loans and leases:

Loans and leases with no specific reserves represent non-accrual loans where the estimated collateral, less estimated cost to sell, equals or exceeds the net realizable value of the loan. As part of the underwriting process, as well as our ongoing monitoring efforts, we evaluate sufficiency of collateral to protect our interest in the related loan or lease. As a result of this practice, a significant portion of our outstanding balance of non-accrual loans or leases may not require additional specific reserves or require only a minimal amount of required specific reserve. Management is proactive in recording charge-offs to bring loans to their net realizable value in situations where it is determined with certainty that we will not recover the entire amount of our principal. This practice may lead to a lower allowance for credit loss to non-accrual loans and leases ratio as compared to our peers or industry expectations.

In 2025, as well as in all previous reporting periods, there were no loans over 90 days past due and still accruing interest. Loans and leases greater than 90 days past due are considered non-accrual and are placed on non-accrual status. Cash received while a loan or a lease is on non-accrual status is applied against the outstanding principal. If collectability of the contractual principal and interest is not in doubt, payments received may be applied to both interest due on a cash basis and principal.

Allowance for Credit Losses

The allowance for credit losses ("ACL"), including unfunded commitment reserves, increased $424,000, or 1.1%, to $37.7 million as of December 31, 2025, from $37.3 million as of December 31, 2024. A summary of the activity in the ACL, inclusive of reserves for unfunded credit commitments, follows:

The Corporation recognized $8.7 million of provision expense for the year ended December 31, 2025, compared to $8.8 million for the year ended December 31, 2024. The provision expense for the year ended December 31, 2025, was primarily due to $8.2 million in net charge-offs and $2.5 million and $1.5 million increases in the general reserve due to loan growth and changes in quantitative factors, respectively. These increases were partially offset by a $3.4 million decrease in the specific reserves on individually evaluated loans.

The ACL reserve increased compared to prior year primarily driven by higher general reserve requirements and higher reserves on unfunded commitments partially offset by lower specific reserve requirements. General reserves as a percentage of total loans increased to 0.90% as of December 31, 2025 from 0.86% as of December 31, 2024. Specific reserves as a percentage of total loans decreased to 0.16% as of December 31, 2025 from 0.29% as of December 31, 2024.

As a result of our review process, we have concluded an appropriate ACL for the loan and lease portfolio is $37.7 million, or 1.12% of gross loans and leases, at December 31, 2025. However, given complexities of workout situations and the uncertainty surrounding future economic conditions, further charge-offs, and increased provisions for credit losses may be recorded if additional facts and circumstances lead us to a different conclusion.

The table below shows our allocation of the allowance for loan losses by loan portfolio segments. The allocation of the allowance by segment is management’s best estimate of the inherent risk in the respective loan portfolio as described in Allowance for Credit Losses in the Critical Accounting Policies and Estimates section. Despite the specific allocation noted in the table below, the entire allowance is available to cover any loss.

Deposits

As of December 31, 2025, deposits increased $273.3 million, or 8.8%, to $3.380 billion from $3.107 billion at December 31, 2024. The increase in deposits was primarily due to increases of $138.1 million, $99.8 million, and $96.1 million in interest-bearing transaction accounts, certificates of deposits, and money market accounts, respectively. These increases were partially offset by decreases of $57.3 million and $3.3 million in non-interest-bearing transaction accounts and wholesale deposits, respectively.

The following table presents the composition of the Bank's consolidated deposits:

Total period end core deposits for the year ended December 31, 2025 were approximately $2.673 billion, or 74.7% of total bank funding. Total bank funding is defined as total deposits plus FHLB advances. This compares to ending core deposits of $2.396 billion, or 71.5% of total bank funding, for 2024.

Period-end deposit balances associated with core deposit relationships will fluctuate based upon maturity of time deposits, client demands for the use of their cash, and our ability to maintain existing and acquire new client relationships. Deposits continue to be the primary source of the Bank’s funding for lending and other investment activities. A variety of accounts are designed to attract both short- and long-term deposits. These accounts include non-interest-bearing transaction accounts, interest-bearing transaction accounts, money market accounts, and certificates of deposit. Deposit terms offered by the Bank vary according to the minimum balance required, the time period the funds must remain on deposit, the rates and products offered by competitors, and the interest rates charged on other sources of funds, among other factors. Our Bank’s core deposits are obtained primarily from Wisconsin and the greater Kansas City Metro. Deposit growth is supported by dedicated treasury management sales resources that focus on the origination of commercial operating accounts, in contrast to branch‑centric or digital acquisition sales models commonly employed by peer institutions. We believe this approach continues to contribute to the growth of core deposits and to the overall stability of the Bank’s funding profile.

The following table sets forth the amount and maturities of the Bank's certificates of deposit and term wholesale deposits at December 31, 2025:

At December 31, 2025, time deposits included $113.0 million of certificates of deposit and wholesale deposits in denominations greater than or equal to $250,000. Of these certificates, $41.4 million are scheduled to mature in three months or less, $21.6 million in greater than three through six months, $39.2 million in greater than six through twelve months and $10.8 million in greater than twelve months.

A summary of annual maturities of core and wholesale certificates of deposit at December 31, 2025 is as follows:

As of December 31, 2025, we have no wholesale certificates of deposit which the Bank has the right to call prior to the scheduled maturity.

Borrowings

We had total borrowings of $252.1 million as of December 31, 2025, a decrease of $68.0 million, or 21.25%, from $320.0 million at December 31, 2024. The Bank elected to utilize more wholesale deposits in lieu of FHLB advances in consideration of liquidity risk management and business strategy. Total wholesale funding as a percentage of total bank funding was 25.3% as of December 31, 2025, compared to 28.9% as of December 31, 2024. Total bank funding is defined as total deposits plus FHLB advances.

Please refer to the section entitled Liquidity and Capital Resources, below, for further information regarding our use and monitoring of wholesale funds.

The following table sets forth the outstanding balances, weighted average balances, and weighted average interest rates for our borrowings (short-term and long-term) as indicated.

A summary of annual maturities of borrowings at December 31, 2025, is as follows:

The aggregate principal amount of the 2024 issuance of subordinated notes payable was $20.0 million. The subordinated notes payable bear a fixed interest rate of 7.5% with a maturity date of September 13, 2034.

Stockholders' Equity

As of December 31, 2025, stockholders’ equity was $371.6 million, or 9.10% of total assets, compared to stockholders’ equity of $328.6 million, or 8.53% of total assets, as of December 31, 2024. Stockholders’ equity increased by $43.0 million during the year ended December 31, 2025. The increase was due to net income of $50.3 million for the year ended December 31, 2025, partially offset by preferred and common stock dividend declarations of $875,000 and $9.7 million, respectively.

The Corporation issued 12,500 shares, or $12.5 million in aggregate liquidation preference, of 7.0% Fixed-to-Floating Rate Non-Cumulative Perpetual Preferred Stock, Series A, par value $0.01 per share, with a liquidation preference of $1,000 per share (the “Series A Preferred Stock”) in a private placement to institutional investors. The net proceeds received from the issuance of the Series A Preferred Stock were $12.0 million.

The Corporation expects to pay dividends on the Series A Preferred Stock when and if declared by its Board, at a fixed rate of 7.0% per annum, payable quarterly, in arrears, on March 15, June 15, September 15 and December 15 of each year up to, but excluding, March 15, 2027. For each dividend period from and including March 15, 2027, dividends will be paid at a floating rate of

Table of Contents

Three-Month Term SOFR plus a spread of 539 basis points per annum. During the year ended December 31, 2025, the Corporation paid $875,000 in preferred cash dividends. The Series A Preferred Stock is perpetual and has no stated maturity. The Corporation may redeem the Series A Preferred Stock at its option at a redemption price equal to $1,000 per share, plus any declared and unpaid dividends (without regard to any undeclared dividends), subject to regulatory approval, on or after March 15, 2027 or within 90 days following a regulatory capital treatment event, in accordance with the terms of the Series A Preferred Stock.

On April 26, 2024, the Corporation’s Board of Directors authorized the repurchase by the Corporation of shares of its common stock with a maximum aggregate purchase price of $5.0 million, in such quantities, at such prices and on such other terms and conditions as the Corporation’s Chief Executive Officer or Chief Financial Officer determine in their discretion to be in the best interests of the Corporation and its shareholders, any time with no expiration date. As of December 31, 2025, the Corporation has not repurchased any shares under this repurchase program.

Liquidity and Capital Resources

The Corporation expects to meet its liquidity needs through existing cash on hand, established cash flow sources, its third party senior line of credit, and dividends received from the Bank. While the Bank is subject to certain generally applicable regulatory limitations regarding its ability to pay dividends to the Corporation, we do not believe that the Corporation will be adversely affected by these dividend limitations. The Corporation’s principal liquidity requirements at December 31, 2025, were the interest payments due on subordinated notes and cash dividends payable to both common and preferred stockholders. During 2025 and 2024, FBB declared and paid cash dividends totaling $13.5 million and $11.5 million, respectively. The capital ratios of the Bank met all applicable regulatory capital adequacy requirements in effect on December 31, 2025, and continue to meet the heightened requirements imposed by Basel III, including the capital conservation buffer. The Corporation’s Board and management teams adhere to the appropriate regulatory guidelines on decisions which affect their capital positions, including but not limited to, decisions relating to the payment of dividends and increasing indebtedness.

The Bank maintains liquidity by obtaining funds from several sources. The Bank’s primary source of funds are principal and interest payments on loans receivable and mortgage-related securities and deposits and other borrowings, such as federal funds and FHLB advances. The scheduled payments of loans and mortgage-related securities are generally a predictable source of funds. Deposit flows and loan prepayments, however, are greatly influenced by general interest rates, economic conditions, and competition.

Sources of Liquidity

(1)
Bank internal policy limits brokered CDs to 50% of total bank funding when combined with value of unencumbered pledged loans.

We view readily accessible liquidity as a critical element to meet our cash and collateral obligations. We define our readily accessible liquidity as the total of our short-term investments, our unencumbered securities available-for-sale, and our unencumbered pledged loans. Our readily accessible liquidity increased $506.8 million from December 31, 2024, due primarily to engagement with the FRB to confirm pledge value of additional loans. As of December 31, 2025, and 2024, our readily accessible liquidity was $1.390 billion and $882.8 million, respectively. At December 31, 2025, and 2024, the Bank had $7.7 million and $127.8 million on deposit with the

Table of Contents

FRB recorded in short-term investments, respectively. Any excess funds not used for loan funding or satisfying other cash obligations were maintained as part of our readily accessible liquidity in our interest-bearing accounts with the FRB, as we value the safety and soundness provided by the FRB. We plan to utilize excess liquidity to fund loan and lease portfolio growth, pay down maturing debt, allow run off of maturing wholesale certificates of deposit or invest in securities to maintain adequate liquidity at an improved margin.

We had $904.7 million of outstanding wholesale funds at December 31, 2025, compared to $976.1 million of wholesale funds as of December 31, 2024, which represented 25.3% and 28.9%, respectively, of period end total bank funding. Wholesale funds include FHLB advances and brokered deposits. Total bank funding is defined as total deposits plus FHLB advances. We are committed to raising core deposits while utilizing wholesale funds to mitigate interest rate risk. Wholesale funds continue to be an efficient and cost effective source of funding for the Bank and allows it to gather funds across a larger geographic base at price levels and maturities that are more attractive than local time deposits when required to raise a similar level of core deposits within a short time period. Access to such deposits and borrowings allows us the flexibility to refrain from pursuing non-relationship based deposits in markets that may have experienced unfavorable pricing levels. The administrative costs associated with wholesale funds are considerably lower than those that would be incurred to administer a similar level of core deposits with a similar maturity structure. During the time frames necessary to accumulate wholesale funds in an orderly manner, we will use short-term FHLB advances to meet any temporary funding needs. The short-term FHLB advances will typically have terms of one week to one month to cover expected funding demands.

Period-end core deposits increased $276.6 million, or 11.5%, to $2.673 billion at December 31, 2025, from $2.396 billion at December 31, 2024, as core deposit balances increased due to successful business development efforts, partially offset by clients funding their normal course of business. Our core relationships continue to grow; however, deposit balances associated with those relationships will fluctuate. We expect to establish new client relationships and continue marketing efforts aimed at increasing the balances in existing clients’ deposit accounts. Nonetheless, we will continue to use wholesale funds in specific maturity periods, typically three to five years, needed to effectively mitigate the interest rate risk measured through our asset/liability management process or in shorter time periods if core deposit balances decline. In order to provide for ongoing liquidity and funding, substantially all of our wholesale funds are certificates of deposit which do not allow for withdrawal at the option of the depositor before the stated maturity (with the exception of deposits accumulated through the internet listing service which have the same early withdrawal privileges and fees as do our other core deposits) and FHLB advances with contractual maturity terms and no call provisions. The Bank limits the percentage of wholesale funds to total bank funds in accordance with liquidity policies approved by its Board. The Bank was in compliance with its policy limits as of December 31, 2025.

We will continue to use wholesale funds in specific maturity periods, typically three to five years, needed to effectively mitigate the interest rate risk measured through our asset/liability management process or in shorter time periods if core deposit balances decline. In order to provide for ongoing liquidity and funding, none of our wholesale certificates of deposit allow for withdrawal at the option of the depositor before the stated maturity date and FHLB advances have contractual maturity terms. The Bank limits the percentage of wholesale funds to total bank funds in accordance with liquidity policies approved by its Board. The Bank was in compliance with its policy limits as of December 31, 2025.

The Bank was able to access the wholesale funding market as needed at rates and terms comparable to market standards during the year ended December 31, 2025. In the event that there is a disruption in the availability of wholesale funds at maturity, the Bank has managed the maturity structure, in compliance with our approved liquidity policy, so at least one year of maturities could be funded through readily available liquidity. These potential funding sources include deposits maintained at the FRB or Federal Reserve Discount Window utilizing currently unencumbered securities and acceptable loans as collateral. As of December 31, 2025, the readily available liquidity was in excess of the stated policy minimum. We believe the Bank will also have access to the unused federal funds lines, cash flows from borrower repayments, and cash flows from security maturities. The Bank also has the ability to raise core deposits by offering attractive rates to generate the level required to fulfill its liquidity needs.

The Corporation has on file a shelf registration with the Securities and Exchange Commission that would allow the Corporation to offer and sell, from time to time and in one or more offerings, up to $75.0 million in aggregate initial offering price of common and preferred stock, debt securities, warrants, subscription rights, units, or depository shares, or any combination thereof.

The Bank is required by federal regulation to maintain sufficient liquidity to ensure safe and sound operations. We believe that the Bank has sufficient liquidity to match the balance of net withdrawable deposits and short-term borrowings in light of present economic conditions and deposit flows.

During the year ended December 31, 2025, operating activities resulted in a net cash inflow of $61.7 million driven by net income of $50.3 million. Net cash used in investing activities for the year ended December 31, 2025, was $373.4 million which consisted of $268.3 million in cash outflows to fund net loan growth and $134.6 million in net cash outflows to purchase available-for-sale securities. Net cash provided by financing activities for the year ended December 31, 2025, was $193.5 million. Financing cash flows included a $273.3 million net increase in deposits and a $68.1 million net decrease in FHLB advances, partially offset by cash dividends paid of $9.7 million.

Critical Accounting Policies and Estimates

The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. By their nature, changes in these assumptions and estimates could significantly affect the Corporation’s financial position or results of operations. Actual results could differ from those estimates. Discussed below are certain policies that are critical to the Corporation. We view critical accounting policies to be those which are highly dependent on subjective or complex judgments, estimates and assumptions, and where changes in those estimates and assumptions could have a significant impact on the financial statements.

Allowance for Credit Losses. Management believes the determination of the ACL involves a higher degree of judgment and complexity than its other significant accounting policies. The ACL is calculated with the objective of maintaining a reserve level believed by management to be sufficient to absorb estimated credit losses over the life of an asset or an off-balance sheet credit exposure. Management’s determination of the adequacy of the ACL is based on periodic evaluations of past events, including historical credit loss experience on financial assets with similar risk characteristics, current conditions, and reasonable and supportable forecasts that affect the collectability of the remaining cash flows over the contractual term of the financial assets. However, this evaluation has subjective components requiring material estimates, including expected default probabilities, the expected loss given default, the amounts and timing of expected future cash flows, and estimated losses based on historical loss experience and forecasted economic conditions. All of these factors may be susceptible to significant change. To the extent that actual results differ from management estimates, additional provisions for credit losses may be required that would adversely impact earnings in future periods. The ACL represents our recognition of the risks of extending credit and our evaluation of the quality of the loan and lease portfolio and as such, requires the use of judgment as well as other systematic objective and quantitative methods which may include additional assumptions and estimates.

One of the most significant judgments impacting the ACL estimate is the economic forecast for United States national unemployment and United States national GDP. Changes in the economic forecast could significantly affect the estimated credit losses which could potentially lead to materially different allowance levels from one reporting period to the next. Loans that no longer conform to the risk characteristics of any pool are evaluated individually. This includes all non-accrual loans and leases and may also include other loans and leases that management identifies as non-conforming. Reserves on individually-evaluated loans are estimated based on one or a combination of estimates of fair value of the underlying collateral less cost to sell, seniority of the Bank’s claim, and borrower repayment forecasts. For loans and leases less than $500,000 in the Equipment Finance pool, the recovery value is based on historical experience.

Management also evaluates debt securities for credit losses when a default or decline in fair value is identified.

We also continue to exercise our legal rights and remedies as appropriate in the collection and disposal of non-performing assets and adhere to rigorous underwriting standards in our origination process in order to achieve strong asset quality. Although we believe that the ACL was appropriate as of December 31, 2025, based upon the evaluation of loan and lease delinquencies, non-performing assets, charge-off trends, economic conditions, and other factors, there can be no assurance that future adjustments to the allowance will not be necessary.

Income Taxes. Income tax expense or benefit represents the tax payable or tax refundable for a period, adjusted by the applicable change in deferred tax assets and liabilities for that period. The determination of current and deferred income taxes is based on complex analysis of many factors, including the interpretation of federal and state income tax laws, the difference between the tax and financial reporting basis of assets and liabilities (temporary differences), estimates of amounts currently due or owed, such as the timing of reversals of temporary differences, and current accounting standards. Deferred income taxes are recognized for the future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases. We apply a more likely than not approach to each of our tax positions when determining the amount of tax benefit to record in our Consolidated Financial Statements. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled.

We have made our best estimate of valuation allowances utilizing available evidence and evaluation of sources of taxable income including tax planning strategies and expected reversals of timing differences to determine if valuation allowances were needed for deferred tax assets. Realization of deferred tax assets over time is dependent on our ability to generate sufficient taxable earnings in future periods and a valuation allowance may be necessary if management determines that it is more likely than not that the deferred asset will not be utilized. These estimates and assumptions are subject to change. Changes in these estimates and assumptions could adversely affect future consolidated results of operations. The Corporation believes the tax assets, liabilities, and allowances are properly recorded in the Consolidated Financial Statements.

The Corporation also invests in certain development entities that generate federal historic, low income housing, or renewable energy tax credits. The tax benefits associated with these investments are accounted for either under the flow-through method, equity method, or proportional amortization method and are recognized when the respective project is placed in service or over the investment term.

The federal and state taxing authorities who make assessments based on their determination of tax laws may periodically review our interpretation of federal and state income tax laws. Tax liabilities could differ significantly from the estimates and interpretations used in determining the current and deferred income tax liabilities based on the completion of examinations by taxing authorities.
