**Notes to the Unaudited Consolidated Financial Statements**

**Note *1:* Summary of Significant Accounting Policies**

The accompanying unaudited consolidated financial statements have been prepared in conformity with accounting principles generally accepted in the United States of America ("U.S. GAAP") and conform to practices within the banking industry. The accounting policies followed in the preparation of the interim consolidated financial statements are consistent with those used in the preparation of the annual financial statements. The interim consolidated financial statements reflect all normal and recurring adjustments that are necessary, in the opinion of management, for fair statement of results for the interim periods presented. Results for the *three* and *nine* month periods ended *September 30, 2025*, are *not* necessarily indicative of the results that *may* be expected for the year ending *December 31, 2025.*

**Nature of Operations**

NSTS Bancorp, Inc. ("NSTS" or the "Company", "we" or "our") was formed to serve as the stock holding company for North Shore Trust and Savings (the "Bank") in connection with the conversion of North Shore Trust and Savings, NSTS Financial Corporation and North Shore MHC, into the stock form of organization, which was completed on *January 18, 2022.* Shares of NSTS Bancorp, Inc. stock began trading on *January 19, 2022* on the Nasdaq Capital Market under the trading symbol "NSTS."

**Basis of Presentation**

The accompanying unaudited Consolidated Financial Statements were prepared in accordance with GAAP and the instructions to Form *10*-Q and Rule *10*-*01* of Regulation S-*X.* Accordingly, they do *not* include all of the information and footnotes required by GAAP for complete financial statements and should be read in conjunction with NSTS Bancorp, Inc.'s Consolidated Financial Statements and footnotes thereto included in the Company's Annual Report on Form *10*-K for the year ended *December 31, 2024*. The unaudited Consolidated Financial Statements include the accounts of the Company and its wholly-owned subsidiaries. All significant intercompany balances and transactions have been eliminated in consolidation.

Management is required 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 revenue and expenses during the reporting period. Actual results *may* vary from those estimates. Material estimates that could significantly change in the near-term include the adequacy of the allowance for credit losses, determination of the valuation allowance on deferred tax assets and the valuation of investment securities and the related tax effect. The results of operations for the *three* and *nine* months ended *September 30, 2025*, are *not* necessarily indicative of results that *may* be expected for any other interim period or the entire fiscal year ending *December 31, 2025.* Certain amounts in prior year financial statements have been reclassified to conform to the current presentation. Subsequent events have been evaluated through the date of issuance of the unaudited Consolidated Financial Statements. *No* significant subsequent events have occurred through this date requiring adjustment to the financial statements or disclosures.

All of the Company's financial results are similar and considered by management to be aggregated into one reportable operating segment. While the Company has assigned certain management responsibilities by business-line, the Company's Chief Operating Decision Maker ("CODM") evaluates financial performance on a Company-wide basis. The Company's assigned business lines have similar economic characteristics, products, services and customers. Accordingly, all of the Company's operations are considered by management to be aggregated in one reportable operating segment.

Financial performance is reported to the CODM monthly, and the primary measure of performance is consolidated net income. The allocation of resources throughout the Company is determined annually based upon consolidated net income performance. The presentation of financial performance to the CODM is consistent with amounts and financial statement line items shown in the Company's consolidated balance sheets and consolidated statements of operations. Additionally, the Company's significant expenses are adequately segmented by category and amount in the consolidated statements of operations to include all significant items when considering both qualitative and quantitative factors. Significant expenses of the Company include salaries and employee benefits, equipment and occupancy expense, data processing, professional services and advertising.

On *December 14, 2023,* the FASB issued ASU *2023*-*09* "Income Taxes (Topic *740*): Improvements to Income Tax Disclosures". The amendments require that public business entities on an annual basis (*1*) disclose specific categories in the rate reconciliation, and (*2*) provide additional information for reconciling items that meet a quantitative threshold (if the effect of those reconciling items is equal to or greater than *5* percent of the amount computed by multiplying pretax income (or loss) by the applicable statutory income tax rate). The amendments require that all entities disclose on an annual basis the following information about income taxes paid: (*1*) The amount of income taxes paid (net of refunds received) disaggregated by federal (national), state, and foreign taxes, and (*2*) The amount of income taxes paid (net of refunds received) disaggregated by individual jurisdictions in which income taxes paid (net of refunds received) is equal to or greater than *5* percent of total income taxes paid (net of refunds received). The amendments also require that all entities disclose the following information: (*1*) Income (or loss) from continuing operations before income tax expense (or benefit) disaggregated between domestic and foreign, and (*2*) Income tax expense (or benefit) from continuing operations disaggregated by federal (national), state, and foreign. The ASU is effective for public business entities for annual periods beginning after *December 15, 2024.* Early adoption is permitted for annual financial statements that have *not* yet been issued or made available for issuance. The amendments should be applied on a prospective basis. Retrospective application is permitted. The Company will adopt this ASU, and does *not* expect the amendments to have a material impact to the annual financial statements of the Company.

In *November 2024,* the FASB issued ASU *No. 2024*-*03,* "Income Statement – Reporting Comprehensive Income – Expense Disaggregation Disclosures (Subtopic *220*-*40*)." The pronouncement requires public entities to disclose additional information about specific expense categories in the notes to the financial statements. The guidance is effective for public business entities for fiscal years beginning after *December 15, 2026,* and interim reporting periods beginning after *December 15, 2027.* Early adoption is permitted. The Company is assessing ASU *2024*-*03* and its impact on its Consolidated Financial Statements and disclosures, and does *not* expect the amendments to have a material impact to the annual financial statements of the Company.

**Note *2:* Securities Available for Sale**

The amortized cost and estimated fair value of debt securities at *September 30, 2025* and *December 31, 2024*, by contractual maturity, are shown below. The accrued interest receivable for securities available for sale was $292,000 and $278,000 on *September 30, 2025* and *December 31, 2024,* respectively. Maturities *may* differ from contractual maturities in mortgage-backed securities because the mortgages underlying the securities *may* be called or repaid without any penalties, therefore, these securities have been included in the below table based on average remaining life.

At *September 30, 2025* and *December 31, 2024*, many of the investment securities were in unrealized loss positions. There were *no* securities with identified credit losses at *September 30, 2025* and *December 31, 2024*, respectively. Unrealized losses have *not* been recognized into income because, based on management's evaluation, the decline in fair value is largely due to increased market rates, temporary market conditions and trading spreads, and, as such, are considered to be temporary by the Bank. In addition, management has the intent and ability to hold the securities until they mature or they recover their carrying values.

All U.S. government agency obligations, mortgage-based residential obligations and collateralized mortgage obligations are agency-issued or government-sponsored enterprise issued. Agency-issued securities are generally guaranteed by a U.S. government agency, such as the Government National Mortgage Association. Government-sponsored enterprises, such as the Federal Home Loan Mortgage Corporation, the Federal National Mortgage Association, or the Small Business Administration, have either a direct or implied guarantee by the U.S. government.

The Bank holds *two* classifications of municipal bonds, general obligation bonds and revenue bonds. General obligation bonds are backed by the general revenue of the issuing municipality, while revenue bonds are supported by a specific revenue source. All general obligation and revenue bonds have a bond rating of investment grade by Standard and Poor's or Moody's Investor Services or are *not* rated. There have been *no* declines in investment grades on bonds in a loss position and, as of *September 30, 2025*, all municipal bonds are paying as agreed.

There were no sales of securities available-for-sale during the *nine* months ended *September 30, 2025* and *2024*.

**Note *3:* Loans and allowance for credit losses**

A summary of loans by major category as of *September 30, 2025* and *December 31, 2024* is as follows:

---

| Total loans, net | $132937 | $130356 |

First mortgage loans serviced for others are *not* included in the accompanying balance sheets. The unpaid principal balance of these loans totaled $21.0 million and $13.9 million at *September 30, 2025* and *December 31, 2024*, respectively. Custodial escrow balances maintained in connection with the loans serviced were $231,000 and $236,000 at *September 30, 2025* and *December 31, 2024*, respectively.

The accrued interest receivable for loans, net, was $582,000 and $560,000 for *September 30, 2025* and *December 31, 2024,* respectively

In the normal course of business, loans are made by the Bank to directors and officers of the Company and the Bank (related parties). The terms of these loans, including interest rate and collateral, are similar to those prevailing for comparable transactions with other customers and do *not* involve more than a normal risk of collectability. At *September 30, 2025* and *December 31, 2024*, such borrowers were indebted to the Bank in the aggregate amount of $570,000 and $587,000, respectively.

The ACL on loans excludes $69,000 and $60,000 of allowance for off-balance sheet exposures as of *September 30, 2025* and *2024,* respectively, recorded within Other Liabilities on the Consolidated Balance Sheets. Off-balance sheet exposures consist of unused lines of credit, the unused portion of construction loans and commitments to originate loans. The net provision for credit losses for the *three* and *nine* months ended *September 30, 2025* in the table above excludes a (reversal of) and a provision for credit losses of $(11,000) and $10,000, respectively, related to off balance sheet exposures. The net provision for credit losses for the *three* and *nine* months ended *September 30, 2024* in the table above excludes a provision for credit losses of $16,000 and $47,000, respectively, related to off balance sheet exposures.

As of *September 30, 2025*, there were *two* collateral dependent loan totaling $285,000 in the *one* to *four*-family residential loan segment. These loans are collateralized by residential real estate and have no ACL as of *September 30, 2025.* There were no other collateral dependent loans as of *September 30, 2025.* There were no collateral dependent loans as of *December 31, 2024.* 

The Bank evaluates collectability based on payment activity and other factors. The Bank uses a graded loan rating system as a means of identifying potential problem loans, as follows:

<u>Pass</u>

Loans in these categories are performing as expected with low to average risk.

<u>Special Mention</u>

Loans in this category are internally designated by management as "watch loans." These loans are starting to show signs of potential weakness and are closely monitored by management.

<u>Substandard</u>

Loans in this category are internally designated by management as "substandard." Generally, a loan is considered substandard if it is inadequately protected by the paying capacity of the obligors or the current net worth of the collateral pledged. Substandard loans present a distinct possibility that the Bank will sustain losses if such weaknesses are *not* corrected.

<u>Doubtful</u>

Loans classified as doubtful have all the weaknesses inherent in those designated as "substandard" with the added characteristic that the weaknesses *may* make collection or liquidation in full, on the basis of currently existing facts, highly questionable and improbable.

On an annual basis, or more often if needed, the Bank formally reviews the ratings on commercial loans. In addition, the Bank performs an independent review of a significant portion of the commercial loan portfolio. Management uses the results of the independent review as part of its annual review process.

The Bank *may* modify loans to borrowers experiencing financial difficulty by providing modifications to repayment terms; more specifically, modifications to loan interest rates. Management performs an analysis at the time of loan modification. Any reserve required is recorded through a provision to the allowance for credit losses on loans. There were no modifications on loans to borrowers experiencing financial difficulty during the *nine* months ended *September 30, 2025* and *2024*.

**Note *6:* Fair Value Measurements**

Fair value is the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. Fair value measurements must maximize the use of observable inputs and minimize the use of unobservable inputs. There is a hierarchy of *three* levels of inputs that *may* be used to measure fair value:

---

| | |
|:---|:---|
| **Level *1*** | Quoted prices in active markets for identical assets or liabilities |

---

---

| | |
|:---|:---|
| **Level *2*** | Observable inputs other than Level *1* prices, such as quoted prices for similar assets or liabilities; quoted prices in markets that are *not* active; or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the assets or liabilities |

---

---

| | |
|:---|:---|
| **Level *3*** | Unobservable inputs supported by little or *no* market activity and are significant to the fair value of the assets or liabilities |

---

An asset's fair value measurement level within the fair value hierarchy is based on the lowest level of any input that is significant to the fair value measurement.

Following is a description of the valuation methodologies used for assets measured at fair value. There have been *no* changes in the methodologies used at *September 30, 2025* or *December 31, 2024*.

<u>Securities available for sale (Recurring)</u>

Where quoted market prices are available in an active market, securities such as U.S. Treasuries, would be classified within Level *1* of the valuation hierarchy. If quoted market prices are *not* available, then fair values are estimated by using quoted prices of securities with similar characteristics or independent asset pricing services and pricing models, the inputs of which are market-based or independently sourced market parameters, including, but *not* limited to, yield curves, interest rates, volatilities, prepayments, defaults, cumulative loss projections and cash flows. Such securities are classified in Level *2* of the valuation hierarchy. In certain cases where Level *1* or Level *2* inputs are *not* available, securities would be classified within Level *3* of the hierarchy.

<u>Individually Evaluated (Nonrecurring)</u>

Individually evaluated loans are recorded at fair value on a nonrecurring basis. The fair value of loans is generally based on recent real estate appraisals. These appraisals *may* utilize a single valuation approach or a combination of approaches including comparable sales and the income approach. Adjustments are routinely made

in the appraisal process by the independent appraisers to adjust for differences between the comparable sales and income data available. Such adjustments are usually significant and typically result in a Level *3* classification of the inputs for determining fair value. Non-real estate collateral *may* be valued using an appraisal, net book value per the borrower's financial statements, or aging reports, adjusted or discounted based on management's historical knowledge, changes in market conditions from the time of the valuation and management's expertise and knowledge of the client and client's business, resulting in a Level *3* fair value classification. Individually evaluated loans are evaluated on a quarterly basis for additional credit losses and adjusted accordingly.

The Bank *may* be required, from time to time, to measure certain assets and liabilities at fair value on a nonrecurring basis in accordance with accounting principles generally accepted in the United States of America. These include assets that are measured at the lower of cost or market that were recognized at fair value below cost at the end of the period. There were no assets measured at fair value on a nonrecurring basis as of *September 30, 2025* and *December 31, 2024.*

**Note *7:* Fair Value of Financial Instruments**

Financial instruments are classified within the fair value hierarchy using the methodologies described in Note *6* – Fair Value Measurements. The following disclosures include financial instruments that are *not* carried at fair value on the Consolidated Balance Sheets. The calculation of estimated fair values is based on market conditions at a specific point in time and *may not* reflect current or future fair values.

Certain financial instruments generally expose the Company to limited credit risk and have *no* stated maturities or have short-term maturities and carry interest rates that approximate market. The carrying value of these financial instruments assumes to approximate the fair value of these instruments. These instruments include cash and cash equivalents, non-interest bearing deposit accounts, time deposits with other financial institutions, FHLB stock, escrow deposits and accrued interest receivable and payable.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; The carrying amounts and estimated fair values by fair value hierarchy of certain financial instruments are as follows:

**Note *8:* Capital Ratios**

The Bank is subject to various regulatory capital requirements administered by the federal banking agencies. Failure to meet minimum capital requirements can initiate certain mandatory actions by regulators that, if undertaken, could have a direct material effect on the Bank's financial statements. Under capital adequacy guidelines and the regulatory framework for prompt corrective action, the Bank must meet specific capital guidelines that involve quantitative measures of the Bank's assets, liabilities and certain off-balance-sheet items as calculated under accounting principles generally accepted in the United States of America, regulatory reporting requirements and regulatory capital standards. The Bank's capital amounts and classification are also subject to qualitative judgments by the regulators about components, risk weightings and other factors.

Quantitative measures established by regulatory reporting standards to ensure capital adequacy require the Bank to maintain minimum amounts and ratios (set forth in the table below) of total and Tier I capital to risk-weighted assets, common equity Tier *1* capital to total risk-weighted assets and of Tier I capital to average assets, as such individual components and calculations are defined by related standards.

As of *September 30, 2025* the most recent notification from the regulators categorized the Bank as well capitalized under the regulatory framework for prompt corrective action. There are *no* conditions or events since that notification which management believes have changed the Bank's category. On *November 13, 2019,* the federal regulators finalized and adopted a regulatory capital rule establishing a community bank leverage ratio ("CBLR"), which became effective on *January 1, 2020.* The intent of CBLR is to provide a simple alternative measure of capital adequacy for electing qualifying depository institutions and depository institution holding companies, as directed under the Economic Growth, Relief, and Consumer Protection Act. Under CBLR, if a qualifying depository institution or depository institution holding company elects to use such measure, such institution or holding company will be considered well capitalized if its ratio of Tier *1* capital to average total consolidated assets (i.e., leverage ratio) exceeds *9%* subject to a limited *two* quarter grace period, during which the leverage ratio cannot drop *100* basis points below the then applicable threshold, and will *not* be required to calculate and report risk-based capital ratios. The Bank elected to begin using CBLR for the *first* quarter of *2020.* Management believes, as of *September 30, 2025*, that the Bank met all capital adequacy requirements to which it was subject.

(*1*) As defined by regulatory agencies. Failure to exceed the leverage ratio thresholds required under CBLR in the future, subject to any applicable grace period, would require the Bank to return to the risk-based capital ratio thresholds previously utilized under the fully phased-in Basel III Capital Rules to determine capital adequacy.

**Note *9:* Commitments and Contingencies**

In the ordinary course of business, the Bank has various commitments and contingent liabilities that are *not* reflected in the accompanying financial statements. In the opinion of management, the ultimate disposition of these matters is *not* expected to have a material adverse effect on the financial position of the Bank.

<u>Financial Instruments</u>

The Bank does *not* engage in the use of interest rate swaps or futures, forwards or option contracts.

At *September 30, 2025* and *December 31, 2024*, unused lines of credit and outstanding commitments to originate loans were as follows:

---

|:---|:---|:---|
|  | ***September 30, 2025*** | ***December 31, 2024*** |
|  | **(Dollars in thousands)** | **(Dollars in thousands)** |
| Unused line of credit | $10090 | $8950 |
| Commitments to originate loans | 1934 | 1109 |
| Total commitments | $12024 | $10059 |

---

<u>Concentrations of Credit Risk</u>

The Bank generally originates single-family residential loans within its primary lending area. These loans are secured by the underlying properties.

The Bank maintains its cash in deposit accounts at the Federal Reserve Bank or other institutions, the balances of which *may* exceed federally insured limits. The Bank has *not* experienced any losses in such accounts. The Bank believes it is *not* exposed to any significant credit risk on cash and cash equivalents.

<u>Interest Rate Risk</u>

The Bank assumes interest rate risk (the risk that general interest rate levels will change) as a result of its normal operations. As a result, fair values of its financial instruments will change when interest rate levels change, and that change *may* be either favorable or unfavorable to the Bank. Management attempts to match maturities of assets and liabilities to the extent believed necessary to minimize interest rate risk. However, borrowers with fixed rate obligations are less likely to prepay in a rising rate environment and more likely to prepay in a falling rate environment. Conversely, depositors who are receiving fixed rates are more likely to withdraw funds before maturity in a rising rate environment and less likely to do so in a falling rate environment. Management monitors rates and maturities of assets and liabilities and attempts to minimize interest rate risk by adjusting terms of new loans and deposits and by investing in securities with terms that mitigate the overall interest rate risk.

<u>Litigation</u>

Due to the nature of its business activities, the Bank is at times subject to legal action which arises in the normal course of business. In the opinion of management, the ultimate resolution of these matters is *not* expected to have a material effect on the financial position or results of operations of the Bank.

**Note *10:* Earnings Per Share**

Basic EPS represents income available to common stockholders divided by the weighted-average number of common shares outstanding during the period. Diluted EPS reflects the potential dilution that could occur if securities or other contracts to issue common shares (such as stock options) were exercised or converted into additional common shares that should then share in the earnings of the entity. Diluted EPS is computed by dividing net income attributable to common stockholders by the weighted-average number of common shares outstanding for the period, plus the effect of potential dilutive common share equivalents.

There were no securities or other contracts that had a dilutive effect for the *nine* months ended *September 30, 2025* and *2024,* and the *three* months ended *September 30, 2024,* and therefore the weighted average common shares outstanding used to calculate both basic and diluted EPS are the same. Shares held by the Employee Stock Ownership Plan ("ESOP") that have *not* been allocated to employees in accordance with the terms of the ESOP, referred to as "unallocated ESOP shares", are *not* deemed outstanding for EPS calculations.

All unallocated ESOP shares have been excluded from the calculation of basic and diluted EPS. The Company excluded anti-dilutive share option awards from the computation of diluted earnings per share.

**Note *11:* Stock Based Compensation**

***ESOP***

Employees participate in an Employee Stock Ownership Plan ("ESOP"). The ESOP borrowed funds from the Company to purchase 431,836 shares of stock at $10 per share. The Bank makes discretionary contributions to the ESOP, as well as paying dividends on unallocated shares to the ESOP, and the ESOP uses funds it receives to repay the loan. When loan payments are made, ESOP shares are allocated to participants based on relative compensation. Participants receive the shares at the end of employment. Dividends on allocated shares increase participants accounts.

There were no contributions to the ESOP during the *first nine* months of *2025,* as the annual loan payment will be made during the *fourth* quarter. Expense recorded was $63,000 and $52,000 for the *three* months ended *September 30, 2025* and *2024*, respectively, and is recognized over the service period. Expense recorded was $191,000 and $154,000 for the *nine* months ended *September 30, 2025* and *2024*, respectively, and is recognized over the service period.

Shares held by the ESOP were as follows:

---

| Fair value of unearned shares as of September 30, 2025 and 2024, respectively | $4051 | $3854 |

---

Fair value of unearned shares is based on a stock price of $11.54 and $10.35 as of *September 30, 2025* and *2024*, respectively.

***Equity Incentive Plan***

At the Company's annual meeting of stockholders held on *May 24, 2023,* stockholders approved the NSTS Bancorp, Inc. *2023* Equity Incentive Plan (*"2023* Equity Plan"), which provides for the granting of up to 755,714 shares (215,918 shares of restricted stock and 539,796 shares available for future grants of stock options) of the Company's common stock pursuant to equity awards made under the *2023* Equity Plan.

Stock options granted under the *2023* Equity Plan generally vest in equal annual installments over a service period of five years beginning on the date of grant. The vesting of the options accelerates upon death, disability or following a change in control of the Company. Stock options are generally granted at an exercise price equal to the fair value of the Company's common stock on the grant date based on the closing market price of the Company's common stock on the date of grant, and have an expiration period of ten years. As of *September 30, 2025*, the Company has 26,296 shares available for future grants of stock options under the *2023* Equity Plan.

The Company recognizes compensation expense for the fair values of these awards, which have graded vesting, on a straight-line basis over the requisite service period of the awards. Upon exercise of vested options, management expects to *first* draw on treasury stock as the source for shares.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; *23*

(*1*) Dollars in thousands. The aggregate intrinsic value of outstanding and exercisable options at *September 30, 2025* and *2024* were calculated based on the closing market price of the Company's common stock of *September 30, 2025* and *2024* of $11.54 and $10.35, respectively, per share less the exercise price.

Expected future expense relating to the non-vested options outstanding as of *September 30, 2025* is $1.0 million over a weighted average period of 2.9 years. As of *September 30, 2025*, the Company had 490,500 in outstanding stock options with a weighted average remaining life of 7.9 years outstanding.

Restricted shares granted under the *2023* Equity Plan generally vest in equal annual installments over a service period of five years beginning on the date of grant. The vesting of the awards accelerates upon death, disability or following a change in control of the Company. The product of the number of shares granted and the grant date closing market price of the Company's common stock determines the fair value of restricted shares under the *2023* Equity Plan. Management recognizes compensation expense for the fair value of restricted shares on a straight-line basis over the requisite service period.

As of *September 30, 2025*, the Company has 14,018 shares of restricted stock available for future grants under the *2023* Equity Plan.

**General**

On January 18, 2022, NSTS Bancorp, Inc. ("the Company") became the holding company for North Shore Trust and Savings ("the Bank") when North Shore MHC completed its conversion into the stock holding company form of organization. Shares of the Company's common stock began trading on January 19, 2022 on the Nasdaq Capital Market under the trading symbol "NSTS."

***NSTS Bancorp, Inc.***

NSTS Bancorp, Inc. is a Delaware corporation which was incorporated in September 2021. As a savings and loan holding company, NSTS Bancorp, Inc. is regulated by the Board of Governors of the Federal Reserve System ("Federal Reserve Board"). The Company's primary business activities relate to owning all of the outstanding shares of capital stock of the Bank.

The unaudited financial statements and other financial information contained in this Quarterly Report on Form 10-Q should be read in conjunction with NSTS Bancorp, Inc.'s Consolidated Financial Statements and footnotes thereto included in the Company's Annual Report on Form 10-K for the year ended December 31, 2024.

***North Shore Trust and Savings***

North Shore Trust and Savings, a federally-chartered stock savings institution, was established in 1921 as North Shore Building and Loan, an Illinois-chartered institution. The Bank is a wholly owned subsidiary of NSTS Bancorp, Inc., and operates as a traditional savings institution focused primarily on serving the banking needs of customers in our market area of Lake County, Illinois and adjacent communities. We operate from our headquarters and main banking office in Waukegan, Illinois, as well as two additional full-service branch offices located in Waukegan and Lindenhurst, Illinois. We also have three loan production offices in Chicago, Aurora and Plainfield, Illinois. Our primary business activity is attracting deposits from the general public and using those funds to originate one- to four-family residential mortgage loans and purchase investments. We are subject to comprehensive regulation and examination by the Office of the Comptroller of the Currency (the "OCC").

***Our Business and Franchise***

For over 100 years, we have served Lake County, Illinois and the surrounding communities. We have established deep ties to the community and developed customer relationships which have spanned generations. We pride ourselves in matching our products and services to the needs of the community.

North Shore Trust and Savings is primarily engaged in attracting deposits from the general public and using those funds to invest in loans and securities. Our principal sources of funds are customer deposits, repayments of loans, maturities of investments and funds borrowed from outside sources such as the Federal Home Loan

Bank of Chicago ("FHLB"). These funds are primarily used for the origination of loans, including one- to four-family residential first mortgage loans, commercial real estate mortgage loans, multi-family residential mortgage loans, one- to four- family residential construction loans and consumer loans. North Shore Trust and Savings derives its income principally from interest earned on loans and investment securities, the gain on sale of mortgage loans sold into the secondary mortgage market, and, to a lesser extent, from fees received in connection with the origination of loans, service charges on deposit accounts and for other services. We invest in bank owned life insurance ("BOLI") to provide us with a funding source for our benefit plan obligations. BOLI also generally provides us noninterest income that is non-taxable. North Shore Trust and Savings' primary expenses are interest expense on deposits and borrowings and general operating expenses.

Our business strategy is to continually enhance our products and services with a focus on one- to four- family residential first mortgage loans, and to maintain our holdings of commercial real estate and multi-family residential real estate loans. Our traditional lending market is centered in our retail branch area of Lake County,

**Critical Accounting Policies and Estimates**

Our discussion and analysis of our financial condition and results of operations is based upon our condensed consolidated unaudited interim financial statements for the three and nine months ended September 30, 2025 and 2024, which have been prepared in accordance with U.S. GAAP. The preparation of these financial statements requires us to make estimates, judgments and assumptions that affect the reported amounts of assets and liabilities and the disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of income and expenses during the reporting periods. On an ongoing basis, we evaluate our estimates and assumptions. Our actual results could differ from these estimates.

Of the significant accounting policies used in the preparation of our consolidated financial statements, we have identified certain items as critical accounting policies based on the associated estimates, assumptions, judgments and complexity. See "*Management*'*s Discussion and Analysis of Financial Condition and Results of Operations*—*Critical Accounting Policies*" in our Annual Report on Form 10-K for the year ended December 31, 2024.

**Overview**

This discussion is intended to focus on certain financial information regarding our consolidated company and may not contain all the information that is important to the reader. The purpose of this discussion is to provide the reader with a more thorough understanding of our financial statements. As such, this discussion should be read carefully and in conjunction with the consolidated financial statements and accompanying notes contained elsewhere in this report.

Our results of operations depend, to a large extent, on net interest income, which is the difference between the income earned on our loan and investment portfolios and interest expense on deposits and borrowings. Our net interest income is largely determined by our net interest spread, which is the difference between the average yield earned on interest-earning assets and the average rate paid on interest-bearing liabilities, and the relative amounts of interest-earning assets and interest-bearing liabilities. Results of operations are also affected by our provisions for credit losses, fee income and other noninterest income and noninterest expense. Noninterest expense principally consists of compensation, office occupancy and equipment expense, data processing, advertising and business promotion and other expenses. We expect that our noninterest expenses will increase as we grow and expand our operations. Our results of operations and financial condition are also significantly affected by general economic and competitive conditions, particularly changes in interest rates, changes in accounting guidance, government policies and actions of regulatory authorities.

**Average Balances, Net Interest Income, and Yields Earned and Rates Paid.** The following table shows for the periods indicated the total dollar amount of interest from average interest-earning assets and the resulting yields, as well as the interest expense on average interest-bearing liabilities, expressed both in dollars and rates, and the net interest margin. All average balances are based on daily balances. The table also reflects the yields on the Company's interest-earning assets and costs of interest-bearing liabilities for the periods shown.

**COMPARISON OF OPERATING RESULTS FOR THE three and nine months ended September 30, 2025 and 2024**

***General.*** For the quarter ended September 30, 2025, we had net income of $65,000, compared to a net loss of $171,000 for the quarter ended September 30, 2024. The change is due to an increase in interest and noninterest income, and a reversal of provision for credit losses during the current quarter. These benefits were partially offset by an increase in interest expense and noninterest expenses. For the nine months ended September 30, 2025, we had a net loss of $521,000, compared to a net loss of $743,000 for the nine months ended September 30, 2024. Similarly, the change is due to an increase in interest and noninterest income, and a reversal of provision for credit losses. These benefits were partially offset by an increase in interest expense and noninterest expenses.

***Net Interest Income.*** Net interest income increased $116,000, to $1.9 million for quarter ended September 30, 2025. Our interest rate spread increased to 2.48% for the quarter ended September 30, 2025 from 2.39% for the quarter ended September 30, 2024. Our net interest margin increased to 3.08% for the quarter ended September 30, 2025 compared to 2.96% for the quarter ended September 30, 2024. The increase in interest rate spread and margin is driven by a reduction of higher cost other borrowings. Additionally, the Bank received a loan payoff from a previously charged-off loan, which included $30,000 in interest income.

Average interest-earning assets of $252.8 million for the quarter ended September 30, 2025 increased $5.7 million compared to $247.1 million for the quarter ended September 30, 2024. The increase in average earning assets was driven by an increase in loans and interest-bearing deposits at other banks, funded by an increase in average deposit balances during the period and a reduction in investment securities. The average outstanding balance of loans, net increased to $138.7 million for the quarter ended September 30, 2025, an increase of $3.4 million from $135.3 million for the quarter ended September 30, 2024. Additionally, the average yield earned on those loans outstanding increased 37 basis points to 5.68% for the quarter ended September 30, 2025. This increase is a result of an overall increase in market rates on mortgage loans originated during 2024 and the first half of 2025, and still in our portfolio, the interest paid on a previously charged-off loan, as well as an increased loan demand for specialty portfolio products which are originated at higher interest rates and with additional origination fees.

The cost of interest-bearing liabilities increased 7 basis points for the quarter ended September 30, 2025 compared to the quarter ended September 30, 2024. The net increase in our funding costs was primarily due to an increase in the percentage of interest-bearing liabilities held in higher cost accounts, such as time deposit accounts. For the quarter ended September 30, 2025, 53.5% of interest-bearing deposits were time deposits compared to 48.1% for the quarter ended September 30, 2024. This shift is primarily attributable to higher rates offered on time deposits that ran through 2024 and into 2025. Additionally, the bank saw a reduction in average money market and demand accounts during the third quarter 2025 compared to the third quarter of 2024.

Net interest income increased $262,000, to $5.6 million for the nine months ended September 30, 2025 compared to $5.3 million for the nine months ended September 30, 2024. Our interest rate spread decreased to 2.29% for the nine months ended September 30, 2025 from 2.35% for the nine months ended September 30, 2024. Our net interest margin decreased to 2.89% for the nine months ended September 30, 2025 compared to 2.90% for the nine months ended September 30, 2024. The decrease in interest rate spread and margin is driven by an increased average balance of higher earning interest-bearing liabilities, specifically interest-bearing deposits, as a percentage of total assets.

Average interest-earning assets of $257.8 million for the nine months ended September 30, 2025 increased $13.2 million compared to $244.6 million for the nine months ended September 30, 2024. The increase in average earning assets was driven by an increase in loans, net and interest-bearing deposits at other banks, funded by an increase in average deposit balances during the period and a reduction in investment securities. The average outstanding balance of loans, net increased to $135.9 million for the nine months ended September 30, 2025, an increase of $4.1 million from $131.8 million for the nine months ended September 30, 2024. Additionally, the average yield earned on those loans outstanding increased 41 basis points to 5.46% for the nine months ended September 30, 2025. This increase is a result of an overall increase in market rates on mortgage loans originated during 2024 and the first half of 2025 and still in our portfolio, the interest paid on a previously charged-off loan, as well as an increased loan demand for specialty portfolio products which are originated at higher interest rates and with additional origination fees.

The cost of interest-bearing liabilities increased 19 basis points for the nine months ended September 30, 2025 compared to the nine months ended September 30, 2024. The net increase in our funding costs was primarily due to an increase in rates earned on time deposit accounts to remain competitive with the local market. The average yield on time deposits for the nine months ended September 30, 2025 was 3.48%.

***Provision for Credit Losses.*** During the quarter ended September 30, 2025, we recorded a reversal of provision for credit losses of $(50,000) comprised of a $(39,000) reversal of provision for credit losses on loans and $(11,000) reversal of provision for credit losses related to unfunded commitments. During the three months ended September 30, 2024, we recorded a provision for credit losses of $20,000, comprised of $4,000 in provision for credit losses to loans and $16,000 in provision for credit losses related to unfunded commitments, including loans committed for origination. During the three months ended September 30, 2025, the Bank received a payoff on a loan previously charged-off totaling $99,000, resulting in a recovery to the allowance for credit losses. During the nine months ended September 30, 2025, we recorded a reversal of provision for credit losses of $(30,000), comprised of a $(40,000) reversal of provision for credit losses on loans and $10,000 provision for credit losses related to unfunded commitments. During the nine months ended September 30, 2024, we recorded a provision for credit losses of $142,000, comprised of $95,000 provision for credit losses on loans and $47,000 provision for credit losses related to unfunded commitments.

We will continue to assess and evaluate the estimated future credit loss impact of current market conditions in subsequent reporting periods, which will be highly dependent on credit quality, macroeconomic forecasts and conditions, as well as the composition of our loan and available-for-sale securities portfolios.

| Total noninterest income | $564 | $423 | $1633 | $1236 |

---

For the quarter ended September 30, 2025 compared to the same period ended September 30, 2024, noninterest income increased $141,000 to $564,000. Noninterest income increased $397,000 for the nine months ended September 30, 2025 to $1.6 million compared to $1.2 million for the nine months ended September 30, 2024. The increases were driven by an increase in the gain on sale of mortgage loans during the quarter and nine months ended September 30, 2025. The increase in gain on sale of mortgages was primarily the result of an overall increase in total mortgage loans originated for sale during the periods. During the quarter ended September 30, 2025, we sold 66 loans totaling $19.4 million for a gain on sale of $393,000. During the quarter ended September 30, 2024, we sold 53 loans totaling $13.8 million for a gain on sale of $268,000. During the nine months ended September 30, 2025, we sold 176 loans totaling $57.3 million for a gain on sale of $1.1 million. During the nine months ended September 30, 2024, we sold 125 loans totaling $33.3 million for a gain on sale of $695,000. Management continues to look for opportunities and markets to sell loans as we continue to see increased loan production compared to prior years.

***Noninterest Expense.*** The following table shows the components of noninterest expense for the periods presented.

| Other | 124 | 136 | 412 | 386 |
| Total noninterest expense | $2495 | $2404 | $7769 | $7160 |

---

Noninterest expenses increased $609,000 for the nine months ended September 30, 2025, compared to the same period ended September 30, 2024. The increase in noninterest expenses was primarily driven by increases in salaries and employee benefits, data processing related expenses, loan expenses and deposit expenses. The average number of employees increased to 52 for the nine months ended September 30, 2025 compared to 49 for the nine months ended September 30, 2024. The increase in headcount is based on additional loan officers brought in during 2024 and 2025. The increase in data processing costs was driven by system upgrades. Loan expenses increased as a result of an increase in loan originations during the period as well as a provision for recourse reserve related to the loans sold into the secondary market due to an increase in the volume of loans sold over the past 4 quarters. Deposit expenses increased as a result of ATM losses totaling $40,000 due to an ATM robbery.

***Provision for Income Tax Expense.*** There was no provision for income tax expense recorded during the three and nine months ended September 30, 2025 and 2024. Management estimates a taxable net loss for the year ended December 31, 2025 due to non-taxable income, such as income on tax exempt municipal securities and BOLI.

During the quarter ended September 30, 2025, management assessed the available positive and negative evidence to estimate whether sufficient future taxable income will be generated to permit use of the existing net operating losses. A significant piece of objective negative evidence evaluated is the cumulative taxable loss incurred over the three-year period ended September 30, 2025. Such objective evidence limits the ability to consider other subjective evidence, such as our projections for future growth. On the basis of this evaluation, as of September 30, 2025, management maintained the valuation allowance against the federal net operating losses and net deferred tax assets to recognize only the portion of the deferred tax asset that is more likely than not to be realized. The amount of the deferred tax asset considered realizable, however, could be adjusted.

***Total Assets****.* Total assets decreased $8.9 million to $269.8 as of September 30, 2025 compared to $278.7 million at December 31, 2024. The decrease was driven by a reduction in cash and cash equivalents due to the paydown of the FHLB Advance during June 2025 and a reduction in deposits.

***Cash and cash equivalents.*** Cash and cash equivalents decreased $19.4 million to $34.1 million as of September 30, 2025, from $53.5 million at December 31, 2024. The decrease was driven by the paydown of the FHLB Advance in June 2025 of $5.0 million. Additionally, deposits decreased $4.1 million, reducing interest-earning bank deposits. Further, the Bank purchased securities available for sale, totaling $10.9 million during the nine months ended September 30, 2025. Currently, the Bank holds a majority of the cash on hand at the Federal Reserve Bank of Chicago, earning 4.15%, to keep the funds available for increasing loan demand. Management continues to actively monitor our liquidity position on a daily basis and maintain levels of liquid assets deemed adequate.

***Securities Available for Sale***. Securities available-for-sale increased to $79.6 million as of September 30, 2025, compared to $71.2 million at December 31, 2024. The Bank purchased $10.9 million of securities available-for-sale during the nine months ended September 30, 2025. There were no sales of securities available for sale during the period. During the nine months ended September 30, 2025, the Bank received principal payments of $4.4 million, had maturities of $1.1 million, had net premium amortization and discount accretion of $359,000 and had a decrease in the unrealized loss on the portfolio of $3.3 million.

As of September 30, 2025, the securities available for sale portfolio included an unrealized loss position of $8.7 million, or 9.9% of the total book value of the portfolio. Management monitors the portfolio for credit losses and believes that the decline in value does not presently represent realized losses and is due to market volatility and increased market interest rates. While the Bank does not currently intend to sell securities in a loss position, management may consider the opportunity to reposition the investment securities portfolio in the future.

***Loans held for sale.*** Our loans held for sale increased $882,000 to $2.1 million at September 30, 2025 compared to $1.2 million at December 31, 2024. The increase was primarily due an overall increase in the level of loans originated for sale during the third quarter of 2025. During the nine months ended September 30, 2025, the Bank originated $55.4 million in loans held for sale.

***Loans, net***. Our loans, net, increased by $2.5 million to $132.9 million at September 30, 2025 compared to $130.4 million at December 31, 2024. The Bank originated $26.1 million in loans to be held in the portfolio during the nine months ended September 30, 2025 and had loan principal payments and payoffs of $23.6 million. In an effort to continue to grow loan originations, the Bank has hired additional mortgage loan originators during the nine months ended September 30, 2025 and continues to look to hire additional loan officers.

As of September 30, 2025, the allowance for credit losses on loans ("ACL") totaled $1.3 million, with a net change of approximately $59,000 during the nine months ended September 30, 2025. While the balance of the ACL remained steady, the ACL as a percentage of the loans, net of unearned income increased, driven by a shift in the portfolio mix, with an increase in construction loans which have a higher peer proxy rate. As of September 30, 2025, there were two loans individually assessed, of which neither had credit losses identified. The Bank actively monitors the loan portfolio for signs of weakening credit quality, noting as of September 30, 2025 the portfolio remains of high quality with limited credit concerns.

***Deposits***. Total deposits decreased $4.1 million to $186.1 million at September 30, 2025 compared to $190.2 million at December 31, 2024. The decrease was primarily driven by a reduction in balances held in savings and money market accounts, some of which shifted into Time Deposits. The Bank had a large estate, totaling $1.7 million, pay out during the year. Management continues to actively monitor the deposit balances and interest rates offered to maintain an adequate level of liquidity.

***Total Equity***. Total equity increased $2.4 million to $78.9 million at September 30, 2025. The increase is primarily due to a decrease in the unrealized loss position on the securities available-for-sale portfolio during the nine months ended September 30, 2025, partially offset by net losses of $521,000.

**Liquidity and Capital Resources**

The Bank maintains levels of liquid assets deemed adequate by management. We adjust our liquidity levels to fund deposit outflows, repay our borrowings, and to fund loan commitments. We also adjust liquidity, as appropriate, to meet asset and liability management objectives.

Liquidity describes our ability to meet the financial obligations that arise in the ordinary course of business. Liquidity is primarily needed to meet the borrowing and deposit withdrawal requirements of our customers and to fund current and planned expenditures. Our primary sources of funds are deposits, principal and interest payments on loans and securities, and proceeds from maturities of securities. We also have the ability to borrow from the FHLB of Chicago and a $10.0 million unsecured Fed Funds line of credit with BMO Harris Bank. At September 30, 2025, we had the capacity to borrow approximately $78.5 million from the FHLB of Chicago. At September 30, 2025, we had no outstanding borrowings.

While maturities and scheduled amortization of loans and securities are predictable sources of funds, deposit flows and loan prepayments are greatly influenced by general interest rates, economic conditions, and competition. Our most liquid assets are cash and short-term investments. The levels of these assets are dependent on our operating, financing, lending, and investing activities during any given period.

Our cash flows are comprised of three primary classifications: cash flows from operating activities, investing activities, and financing activities. Net cash provided by operating activities was $841,000 and $74,000 for the nine months ended September 30, 2025 and 2024, respectively. Net cash used in investing activities, which consists primarily of net change in loans receivable and net change in investment securities, was $10.5 million and $7.0 million for the nine months ended September 30, 2025 and 2024, respectively, with the increase in cash used in 2025 driven by investment security purchases. Net cash (used in) provided by financing activities, consisting primarily of the activity in deposit accounts was ($9.7) million and $10.2 million for the nine months ended September 30, 2025 and 2024, respectively. During the nine months ended September 30, 2025, the Bank repaid the $5.0 million FHLB Advance, resulting in additional cash used in financing activities compared to the prior year.

We are committed to maintaining a strong liquidity position. We monitor our liquidity position on a daily basis. We anticipate that we will have sufficient funds to meet our current funding commitments. Time deposits that are scheduled to mature in less than one year from September 30, 2025, totaled $70.4 million. Based on our deposit retention experience and current pricing strategy we anticipate that a significant portion of maturing time deposits will be retained. However, if a substantial portion of these deposits is not retained, we may utilize FHLB of Chicago advances or raise interest rates on deposits to attract new accounts, which may result in higher levels of interest expense.

As of September 30, 2025, the Bank was well capitalized under the regulatory framework for prompt corrective action. During the year ended December 31, 2020, the Bank elected to begin using the CBLR. Under CBLR, if a qualifying depository institution or depository institution holding company elects to use such measure, such institution or holding company will be considered well capitalized if its ratio of Tier 1 capital to average total consolidated assets (i.e., leverage ratio) exceeds 9%, subject to a limited two quarter grace period, during which the leverage ratio cannot go 100 basis points below the then applicable threshold, and will not be required to calculate and report risk-based capital ratios. North Shore Trust and Savings' Tier 1 capital to Average Assets was 24.11% and 23.53% at September 30, 2025 and December 31, 2024, respectively.

**Commitments**. At September 30, 2025, we had $1.9 million of outstanding commitments to originate loans. Our total letters and lines of credit and unused lines of credit totaled $10.1 million at September 30, 2025. The following table summarizes our outstanding commitments to originate loans and to advance additional amounts pursuant to outstanding letters of credit, lines of credit and undisbursed construction loans at September 30, 2025.

**Impact of Inflation and Changing Prices**

The consolidated financial statements and the accompanying notes presented elsewhere in this document have been prepared in accordance with U.S. GAAP, which generally requires the measurement of financial position and operating results in terms of historical dollars without considering the change in the relative purchasing power of money over time and due to inflation. Unlike most industrial companies, virtually all of our assets and liabilities are monetary in nature. As a result, interest rates have a greater impact on our performance than inflation. Interest rates do not necessarily move in the same direction or to the same extent as the prices of goods and services.

**Changes in Accounting Principles**

On December 14, 2023, the FASB issued ASU 2023-09 "Income Taxes (Topic 740): Improvements to Income Tax Disclosures". The amendments require that public business entities on an annual basis (1) disclose specific categories in the rate reconciliation, and (2) provide additional information for reconciling items that meet a quantitative threshold (if the effect of those reconciling items is equal to or greater than 5 percent of the amount computed by multiplying pretax income (or loss) by the applicable statutory income tax rate). The amendments require that all entities disclose on an annual basis the following information about income taxes paid: (1) The amount of income taxes paid (net of refunds received) disaggregated by federal (national), state, and foreign taxes, and (2) The amount of income taxes paid (net of refunds received) disaggregated by individual jurisdictions in which income taxes paid (net of refunds received) is equal to or greater than 5 percent of total income taxes paid (net of refunds received). The amendments also require that all entities disclose the following information: (1) Income (or loss) from continuing operations before income tax expense (or benefit) disaggregated between domestic and foreign, and (2) Income tax expense (or benefit) from continuing operations disaggregated by federal (national), state, and foreign. The ASU is effective for public business entities for annual periods beginning after December 15, 2024. Early adoption is permitted for annual financial statements that have not yet been issued or made available for issuance. The amendments should be applied on a prospective basis. Retrospective application is permitted. The Company will adopt this ASU, and does not expect the amendments to have a material impact to the annual financial statements of the Company.

In November 2024, the FASB issued ASU No. 2024-03, "Income Statement – Reporting Comprehensive Income – Expense Disaggregation Disclosures (Subtopic 220-40)." The pronouncement requires public entities to disclose additional information about specific expense categories in the notes to the financial statements. The guidance is effective for public business entities for fiscal years beginning after December 15, 2026, and interim reporting periods beginning after December 15, 2027. Early adoption is permitted. The Company is assessing ASU 2024-03 and its impact on its Consolidated Financial Statements and disclosures.

**ITEM 4. CONTROLS AND PROCEDURES**

We maintain disclosure controls and procedures that are designed to provide assurance that the information required to be disclosed in the reports filed or submitted under the Securities Exchange Act of 1934 is recorded, processed, summarized, and reported within the time periods specified in the rules and forms of the SEC. Under the supervision and with the participation of our management, including our principal executive officer and principal financial officer, we evaluated the effectiveness of the design and operation of our disclosure controls and procedures (as defined in Rule 13a-15(e) and 15d-15(e) under the Exchange Act) as of the end of the period covered by this report.

There were no changes in our internal control over financial reporting during the quarter ended September 30, 2025, that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

**PART II. OTHER INFORMATION**
