Note 1: Nature of business

The Bank of N.T. Butterfield & Son Limited (“Butterfield”, the “Bank” or the “Company”) is incorporated under the laws of Bermuda and has a banking license under the Banks and Deposit Companies Act, 1999 (“the Act”). Butterfield is regulated by the Bermuda Monetary Authority (“BMA”), which operates in accordance with Basel principles.

Butterfield is a full service bank and wealth manager headquartered in Hamilton, Bermuda. The Bank operates its business through three geographic segments: Bermuda, Cayman, and the Channel Islands and the UK, where its principal banking operations are located and where it offers specialized financial services. Butterfield offers banking services, comprised of retail and corporate banking, and wealth management, which consists of trust, private banking, and asset management. In the Bermuda, Cayman, and Channel Islands and the UK segments, Butterfield offers both banking and wealth management services. Butterfield also has operations in the jurisdictions of The Bahamas, Canada, Mauritius, Singapore and Switzerland, which are included in our Other segment.

The Bank's common shares trade on the New York Stock Exchange ("NYSE") under the symbol "NTB" and on the Bermuda Stock Exchange ("BSX") under the symbol "NTB.BH".

Note 2: Significant accounting policies

The accompanying unaudited interim consolidated financial statements of the Bank have been prepared in accordance with accounting principles generally accepted in the United States of America (“GAAP”) for interim financial information and should be read in conjunction with the Bank’s audited financial statements for the year ended December 31, 2025.

In the opinion of Management, these unaudited interim consolidated financial statements reflect all adjustments (consisting primarily of normal recurring accruals) considered necessary for a fair statement of the Bank’s financial position and results of operations as at the end of and for the periods presented. The Bank’s results for interim periods are not necessarily indicative of results for the full year. Certain prior year figures have been reclassified to agree to current period presentation.

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 disclosures of contingent assets and liabilities at the date of the unaudited consolidated financial statements and the reported amounts of revenues and expenses during the reporting period, and actual results could differ from those estimates. Management believes that the most critical accounting estimates upon which the financial condition depends, and which involve the most complex or subjective decisions or assessments, are as follows:

•Allowance for credit losses

•Fair value of financial instruments

•Impairment of goodwill and intangibles

•Employee benefit plans

Acquired Loans

Effective January 1, 2026, the Bank elected to early adopt ASU No. 2025-08. This standard introduces a single accounting framework for certain acquired loans, requiring entities to recognize an allowance for credit losses at acquisition which is added to the purchase price (the gross-up approach). In accordance with the transition provisions, the Bank will apply the amendments prospectively to all qualifying purchased seasoned loans acquired on or after the adoption date. The adoption of this guidance simplifies acquisition accounting by removing the 'Day 1 double count' of credit losses for these portfolios.

New Accounting Pronouncements

There were no accounting developments issued during the six months ended June 30, 2026 or accounting standards pending adoption which impacted the Bank.

Note 5: Investment in securities

Amortized Cost, Carrying Amount and Fair Value

On the consolidated balance sheets, available-for-sale ("AFS") investments are carried at fair value and held-to-maturity ('HTM') investments are carried at amortized cost.

¹For the six months ended June 30, 2026 and June 30, 2025, impairments recognized in other comprehensive income for HTM investments were Nil.

Investments with Unrealized Loss Positions

The Bank does not believe that the AFS debt securities that were in an unrealized loss position as of June 30, 2026, comprising 185 securities representing 80.7% of the AFS portfolios' carrying value (December 31, 2025: 156 and 52.1%), represent credit losses. Total gross unrealized AFS losses were 4.9% of the fair value of the affected securities (December 31, 2025: 7.3%).

The Bank’s HTM debt securities are comprised of US government and federal agencies securities and have a zero credit loss assumption under the Current Expected Credit Loss ("CECL") model. HTM debt securities that were in an unrealized loss position as of June 30, 2026, were comprised of 218 securities representing 98.9% of the HTM portfolios’ carrying value (December 31, 2025: 218 and 98.8%). Total gross unrealized HTM losses were 18.2% of the fair value of affected securities (December 31, 2025: 16.9%).

Management does not intend to sell and it is likely that management will not be required to sell the securities prior to the anticipated recovery of the cost of these securities. Unrealized losses were attributable primarily to changes in market interest rates, relative to when the investment securities were purchased, and not due to a decrease in the credit quality of the investment securities. The issuers continue to make timely principal and interest payments on the securities. The following describes the processes for identifying credit impairment in security types with the most significant unrealized losses as shown in the preceding tables.

Management believes that all the US government and federal agencies securities do not have any credit losses, given the explicit and implicit guarantees provided by the US federal government.

Investments in Residential mortgage-backed securities relate to 13 US prime securities (December 31, 2025: 13) which are rated AAA and may possess structural features of securitization, such as subordination, excess spread, over collateralization or other forms of credit enhancement. No credit losses were recognized on these securities as the weighted average credit support and the weighted average loan-to-value ratios range from 15.6% - 50.1% and 41.1% - 51.6%, respectively. Current credit support is significantly greater than any delinquencies experienced on the underlying mortgages.

In the following tables, debt securities with unrealized losses that are not deemed to be credit impaired and for which an allowance for credit losses has not been recorded are categorized as being in a loss position for "less than 12 months" or "12 months or more" based on the point in time that the fair value most recently declined below the amortized

cost basis.

Note 6: Loans

The principal means of securing residential mortgages, personal, credit card and business loans are entitlements over assets and guarantees. Mortgage loans are generally repayable over periods of up to thirty years and personal and business loans are generally repayable over terms not exceeding five years. Government loans are repayable over a variety of terms which are individually negotiated. Amounts owing on credit cards are revolving and typically a minimum amount is due within 30 days from billing. The credit card portfolio is managed as a single portfolio and includes consumer and business cards. The effective yield on total loans as at June 30, 2026 is 5.78% (December 31, 2025: 5.81%). The interest receivable on total loans as at June 30, 2026 is $10.1 million (December 31, 2025: $11.1 million). The interest receivable is included in Accrued interest and other assets on the consolidated balance sheets and is excluded from all loan amounts disclosed in this note.

Loans' Credit Quality

The four credit quality classifications set out in the following tables are defined below and describe the credit quality of the Bank's lending portfolio. These classifications each encompass a range of more granular internal credit rating grades. Loans' internal credit ratings are assigned by the Bank's customer relationship managers as well as members of the Bank's jurisdictional and Group Credit Committees. The borrowers' financial condition is documented at loan origination and maintained periodically thereafter at a frequency which can be up to monthly for certain loans. The loans' performing status, as well as current economic trends, are continuously monitored. The Bank's jurisdictional and Group Credit Committees meet on a monthly basis. The Group Credit Committee is also responsible for approving the allowance for expected credit losses and other impairment charges.

A pass loan shall mean a loan that is expected to be repaid as agreed. A loan is classified as pass where the Bank is not expected to face repayment difficulties because the present and projected cash flows are sufficient to repay the debt and the repayment schedule as established by the agreement is being followed. Loans in this category are reviewed by the Bank’s management on at least an annual basis.

A special mention loan shall mean a loan under close monitoring by the Bank’s management on at least a quarterly basis. Loans in this category are currently still performing, but are potentially weak and present an undue credit risk exposure, but not to the point of justifying a classification of substandard.

A substandard loan shall mean a loan whose evident unreliability makes repayment doubtful and there is a threat of loss to the Bank unless the unreliability is averted. Loans in this category are under close monitoring by the Bank’s management on at least a quarterly basis.

A non-accrual loan shall mean either management is of the opinion full payment of principal or interest is in doubt or that the principal or interest is 90 days past due unless it is a residential mortgage loan which is well secured and collection efforts are reasonably expected to result in amounts due. Loans in this category are under close monitoring by the Bank’s management on at least a quarterly basis.

Changes in Allowances For Credit Losses

The allowance for expected credit losses increased during the six months ended June 30, 2026 compared to December 31, 2025 reflecting an additional specific provision on a legacy non-accrual Bermuda commercial facility. This was partially offset by the release of a provision related to a residential mortgage facility in the Channel Islands and UK segment upon partial repayment. As disclosed in Note 2 of the December 31, 2025 Audited Consolidated Financial Statements, the Bank continuously collects and maintains attributes related to financial instruments within the scope of CECL, including current conditions, and reasonable and supportable assumptions about future economic conditions.

Collateral-dependent loans

Management identified that the repayment of certain commercial and consumer mortgage loans is expected to be provided substantially through the operation or the sale of the collateral pledged to the Bank ("collateral-dependent loans"). The Bank believes that for the vast majority of loans identified as collateral-dependent, the sale of the collateral will be sufficient to fully reimburse the loan's carrying amount.

Non-Performing Loans

During the six months ended June 30, 2026, no interest was recognized on non-accrual loans. No credit deteriorated loans were purchased during the period.

Age analysis and subsequent default of modified loans.

As at June 30, 2026 and June 30, 2025, all loans for which a concession was granted during the preceding 12 months are current, except for the following:

Residential mortgage loans:

–$0.3 million (June 30, 2025: $5.6 million) of residential mortgage loans for which a term extension was granted are 30 to 59 days past due;

–$5.0 million (June 30, 2025: Nil) of residential mortgages loans for which a term extension was granted are 60 to 89 days past due; and

–$26.7 million (June 30, 2025: $0.1 million) of residential mortgage loans for which a term extension and reduction in interest rate was granted and are 90 days or more past due.

Note 7: Credit risk concentrations

Concentrations of credit risk in the lending and off-balance sheet credit-related arrangements portfolios arise when a number of customers are engaged in similar business activities, are in the same geographic region, or when they have similar economic features that would cause their ability to meet contractual obligations to be similarly affected by changes in economic conditions. The Bank regularly monitors various segments of its credit risk portfolio to assess potential concentrations of risks and to obtain collateral when deemed necessary. In the Bank's commercial portfolio, risk concentrations are evaluated primarily by industry and by geographic region of loan origination. In the consumer portfolio, concentrations are evaluated primarily by products. Credit exposures include loans, guarantees and acceptances, letters of credit and commitments for undrawn lines of credit. Unconditionally cancellable credit cards and overdraft lines of credit are excluded from the tables below.

The following table summarizes the credit exposure of the Bank by geographic region. The exposure amounts disclosed below do not include accrued interest and are gross of allowances for credit losses and gross of collateral held.

Note 9: Employee benefit plans

The Bank maintains trusteed pension plans including non-contributory defined benefit plans and a number of defined contribution plans, and provides post-retirement medical benefits to its qualifying retirees. The defined benefit provisions under the pension plans are generally based upon years of service and average salary during the relevant years of employment. The defined benefit and post-retirement medical plans are not open to new participants and are non-contributory and the funding required is provided by the Bank, based upon the advice of independent actuaries. The defined benefit pension plans are in the Bermuda, Guernsey and UK jurisdictions, and the defined benefit post-retirement medical plan is in Bermuda. The Bank has a residual obligation on top of its defined contribution plan in Mauritius.

The Bank included an estimate of the 2026 Bank contribution and estimated benefit payments for the next ten years under the pension and post-retirement plans in its audited financial statements for the year ended December 31, 2025. During the six months ended June 30, 2026, there have been no material revisions to these estimates.

Note 10: Credit related arrangements, repurchase agreements and commitments

Commitments

The Bank enters into contractual commitments to extend credit, normally with fixed expiration dates or termination clauses, at specified rates and for specific purposes. Substantially all of the Bank's commitments to extend credit are contingent upon customers maintaining specific credit standards at the time of loan funding. Management assesses the credit risk associated with certain commitments to extend credit in determining the level of the allowance for expected credit losses.

The Bank has a facility with one of its custodians, whereby the Bank may offer up to $200 million of standby letters of credit to its customers on a fully secured basis. Under the standard terms of the facility, the custodian has the right to set-off against securities held of 110% of the utilized facility. At June 30, 2026, $120.8 million (December 31, 2025: $125.0 million) of standby letters of credit were issued under this facility.

Commitments to extend credit	586,648	577,370
Documentary and commercial letters of credit	758	859
Total unfunded commitments to extend credit	587,406	578,229
Allowance for credit losses	(136)	(131)

Credit-Related Arrangements

Standby letters of credit and letters of guarantee are issued at the request of a Bank customer in order to secure the customer’s payment or performance obligations to a third party. These guarantees represent an irrevocable obligation of the Bank to pay the third party beneficiary upon presentation of the guarantee and satisfaction of the documentary requirements stipulated therein, without investigation as to the validity of the beneficiary’s claim against the customer. Generally, the term of the standby letters of credit does not exceed one year, while the term of the letters of guarantee does not exceed four years. The types and amounts of collateral security held by the Bank for these standby letters of credit and letters of guarantee are generally represented by deposits with the Bank or a charge over assets held in mutual funds.

The Bank considers the fees collected in connection with the issuance of standby letters of credit and letters of guarantee to be representative of the fair value of its obligation undertaken in issuing the guarantee. In accordance with applicable accounting standards related to guarantees, the Bank defers fees collected in connection with the issuance of standby letters of credit and letters of guarantee. The fees are then recognized in income proportionately over the life of the credit agreements. The following table presents the outstanding financial guarantees. Collateral is shown at estimated market value less selling cost. Where the collateral is cash, it is shown gross including accrued income.

Total	228,481	211,995	16,486	246,516	224,326	22,190

Repurchase agreements

The Bank utilizes repurchase agreements and resell agreements (reverse repurchase agreements) to manage liquidity. These agreements are carried at the amounts at which the securities will be subsequently sold or repurchased. The risks of these transactions include changes in the fair value of the securities posted or received as collateral and other credit related events. The Bank manages these risks by ensuring that the collateral involved is appropriate and by monitoring the value of the securities posted or received as collateral on a daily basis.

As at June 30, 2026, the Bank had 15 open positions (December 31, 2025: 13) in resell agreements with a remaining maturity of less than 365 days involving pools of mortgages issued by Non-US government debt securities. The carrying value of these resell agreements is $1.4 billion (December 31, 2025: $1.1 billion) and are included in securities purchased under agreements to resell on the consolidated balance sheets.

Legal Proceedings

There are actions and legal proceedings pending against the Bank and its subsidiaries which arose in the normal course of its business. Management, after reviewing all actions and proceedings pending against or involving the Bank and its subsidiaries, considers that the resolution of these matters would in the aggregate not be material to the consolidated financial position of the Bank.

Note 11: Leases

The Bank enters into operating lease agreements either as the lessee or the lessor, mostly for office and parking spaces as well as for small office equipment. The terms of the existing leases, including renewal options that are reasonably certain to be exercised, extend up to the year 2039. Certain lease payments will be adjusted during the related lease's term based on movements in the relevant consumer price index.

Note 12: Segmented information

The Bank is managed by the Chairman & CEO, its Chief Operating Decision Maker ("CODM"), on a geographic basis. The Bank presents four reportable segments, three geographical and one other: Bermuda, Cayman, Channel Islands and the UK, and Other. The Other segment is composed of several non-reportable operating segments that have been aggregated in accordance with GAAP. The Bermuda, Cayman, and Channel Islands and UK segments have a managing director who reports to the Chairman & CEO. Within the Other segment, each operating segment has a managing director that reports to the Group Head of Trust or Chief Operating Officer who ultimately reports to The Chairman & CEO. The Chairman & CEO and the segment managing director have final authority over resource allocation decisions and performance assessment.

The geographic segments reflect this management structure and the manner in which financial information is currently evaluated by the Chairman & CEO in assessing operating

performance. Segment results are determined based on the Bank's management reporting system, which assigns balance sheet and statement of operations items to each of

the geographic segments. The process is designed around the Bank's organizational and management structure and, accordingly, the results derived are not necessarily

comparable with similar information published by other financial institutions. A description of each reportable segment and table of financial results is presented below.

Accounting policies of the reportable segments are the same as those described in Note 2 of the Bank's audited financial statements for the year ended December 31, 2025. Transactions between segments are accounted for on an accrual basis and are all eliminated upon consolidation. The Bank generally does not allocate assets, revenues and expenses among its business segments, with the exception of certain corporate overhead expenses and loan participation revenue and expenses. Loan participation revenue and expenses are allocated pro-rata based upon the percentage of the total loan funded by each jurisdiction participating in the loan. Other expenses are comprised of marketing, non-service employee benefits and other non-interest expenses.

The Bermuda segment provides a comprehensive range of retail, commercial and private banking services. Retail services are offered to individuals and small to medium-sized businesses through three branch locations and through internet banking, mobile banking, automated teller machines and debit cards. Retail services include deposit services,

consumer and mortgage lending, credit cards and personal insurance products. Commercial banking includes commercial lending and mortgages, cash management, payroll

services, remote banking and letters of credit. Treasury services include money market and foreign exchange activities. Bermuda’s wealth management offering consists of

Butterfield Asset Management Limited, which provides investment management, advisory and brokerage services and Butterfield Trust (Bermuda) Limited, which provides trust,

estate, company management and custody services. Bermuda is also the location of the Bank's head offices and accordingly, retains the unallocated corporate overhead

expenses.

The Cayman segment provides a comprehensive range of retail, commercial and private banking services. Retail services are offered to individuals and small to medium-sized businesses through three branch locations and through internet banking, mobile banking, ATMs and debit cards. Retail services include deposit services, consumer and

mortgage lending, credit cards and property/auto insurance. Commercial banking includes commercial lending and mortgages, cash management, payroll services, remote

banking and letters of credit. Treasury services include money market and foreign exchange activities. Cayman’s wealth management offering comprises investment

management, advisory and brokerage services and Butterfield Trust (Cayman) Limited, which provides trust, estate and company management.

The Channel Islands and the UK segment includes the jurisdictions of Guernsey and Jersey (Channel Islands), and the UK. In the Channel Islands, a broad range of services

are provided to individuals, private clients, trusts, financial institutions and funds including deposit services, mortgage lending, credit cards, private and corporate banking, treasury services, internet banking, wealth management and fiduciary services. The UK jurisdiction provides mortgage services for high-value residential properties.

The Other segment includes the jurisdictions of The Bahamas, Canada, Mauritius, Singapore and Switzerland. These operating segments individually and collectively do not

meet the quantitative threshold for segmented reporting and are therefore aggregated as non-reportable operating segments.

Note 13: Derivative instruments and risk management

The Bank uses derivatives for risk management purposes and to meet the needs of its customers. The Bank’s derivative contracts principally involve over-the-counter ("OTC") transactions that are negotiated privately between the Bank and the counterparty to the contract and include interest rate contracts and foreign exchange contracts.

The Bank may pursue opportunities to reduce its exposure to credit losses on derivatives by entering into International Swaps and Derivatives Associations ("ISDAs") agreements. Depending on the nature of the derivative transaction, bilateral collateral arrangements may be used, as well. When the Bank is engaged in more than one outstanding derivative transaction with the same counterparty, and also has a legally enforceable master netting agreement with that counterparty, the net marked-to-market exposure represents the netting of the positive and negative exposures with that counterparty. When there is a net negative exposure, the Bank regards its credit exposure to the counterparty as being zero. The net marked-to-market position with a particular counterparty represents a reasonable measure of credit risk when there is a legally enforceable master netting agreement between the Bank and that counterparty.

Certain of these agreements contain credit risk-related contingent features in which the counterparty has the option to accelerate cash settlement of the Bank's net derivative liabilities with the counterparty in the event the Bank's credit rating falls below specified levels or the liabilities reach certain levels.

The Bank of N.T. Butterfield & Son Limited

Notes to the Consolidated Financial Statements (unaudited) (continued)

(In thousands of US dollars, unless otherwise stated)

All derivative financial instruments, whether designated as hedges or not, are recorded on the consolidated balance sheets at fair value within other assets or other liabilities. These amounts include the effect of netting. The accounting for changes in the fair value of a derivative in the consolidated statements of operations depends on whether the contract has been designated as a hedge and qualifies for hedge accounting.

Notional Amounts

The notional amounts are not recorded as assets or liabilities on the consolidated balance sheets as they represent the face amount of the contract to which a rate or price is applied to determine the amount of cash flows to be exchanged. Notional amounts represent the volume of outstanding transactions and do not represent the potential gain or loss associated with market risk or credit risk of such instruments. Credit risk is limited to the positive fair value of the derivative instrument, which is significantly less than the notional amount.

Fair Value

Derivative instruments, in the absence of any compensating up-front cash payments, generally have no market value at inception. They obtain value, positive or negative, as relevant interest rates, exchange rates, equity or commodity prices or indices change. The potential for derivatives to increase or decrease in value as a result of the foregoing factors is generally referred to as market risk. Market risk is managed within clearly defined parameters as prescribed by senior management of the Bank. The fair value is defined as the profit or loss associated with replacing the derivative contracts at prevailing market prices.

Risk Management Derivatives

The Bank enters into interest derivative contracts as part of its overall interest rate risk management strategy to minimize significant unplanned fluctuations in earnings that are caused by interest rate volatility. The Bank’s goal is to manage interest rate sensitivity by modifying the repricing or maturity characteristics of certain consolidated balance sheet assets and liabilities so that movements in interest rates do not adversely affect the net interest margin. Derivative instruments that are used as part of the Bank’s risk management strategy include interest rate swap contracts that have indices related to the pricing of specific consolidated balance sheet assets and liabilities. Interest rate swaps generally involve the exchange of fixed and variable-rate interest payments between two parties, based on a common notional principal amount and maturity date. The Bank uses foreign currency derivative instruments to hedge its exposure to foreign currency risk. Certain hedging relationships are formally designated and qualify for hedge accounting as fair value or net investment hedges. Risk management derivatives comprise fair value hedges, net investment hedges and derivatives not formally designated as hedges as described below.

Fair value hedges include designated currency swaps that are used to minimize the Bank's exposure to variability in the fair value of AFS investments due to movements in foreign exchange rates. The effective portion of changes in the fair value of the hedged items attributable to foreign exchange rates is recognized in current year earnings consistent with the related change in fair value of the hedging instrument. For fair value hedges, hedging effectiveness of the hedged item and the hedging instrument are assessed and managed at inception and on an ongoing basis using a partial-term method.

Net investment hedges include designated currency swaps and qualifying non-derivative instruments and are used to minimize the Bank’s exposure to variability in the foreign

currency translation of net investments in foreign operations. The effective portion of changes in the fair value of the hedging instrument is recognized in Accumulated other comprehensive income (loss) ("AOCIL") consistent with the related translation gains and losses of the hedged net investment. For net investment hedges, all critical terms of the hedged item and the hedging instrument are matched at inception and on an ongoing basis to minimize the risk of hedge ineffectiveness.

For derivatives designated as net investment hedges, the Bank follows the method based on changes in spot exchange rates. Accordingly:

- The change in the fair value of the derivative instrument that is reported in AOCIL (i.e., the effective portion) is determined by the changes in spot exchange rates.

- The change in the fair value of the derivative instrument attributable to changes in the difference between the forward rate and spot rate are excluded from the measure

of the hedge ineffectiveness and that difference is reported directly in the consolidated statements of operations under foreign exchange revenue.

Amounts recorded in AOCIL are reclassified to earnings only upon the sale or substantial liquidation of an investment in a foreign subsidiary.

For foreign-currency-denominated financial instruments that are designated as hedges of net investments in foreign operations, the translation gain or loss that is recorded in AOCIL is based on the spot exchange rate between the reporting currency of the Bank and the functional currency of the respective subsidiary. See Note 19: Accumulated other comprehensive income (loss) for details on the amount recognized into AOCIL during the current period from translation gain or loss.

Derivatives not formally designated as hedges are entered into to manage the foreign exchange risk of the Bank's exposure. Changes in the fair value of derivative instruments not formally designated as hedges are recognized in foreign exchange revenue.

Client service derivatives

The Bank enters into foreign exchange contracts primarily to meet the foreign exchange needs of its customers. Foreign exchange contracts are agreements to exchange specific amounts of currencies at a future date at a specified rate of exchange. Changes in the fair value of client services derivative instruments are recognized in foreign exchange revenue.

The following table shows the aggregate notional amounts of derivative contracts outstanding listed by type and respective gross positive or negative fair values and classified by those used for risk management (sub-classified as hedging and those that do not qualify for hedge accounting), client services and credit derivatives. Fair value of derivatives is recorded in the consolidated balance sheets in other assets and other liabilities. Gross positive fair values are recorded in other assets and gross negative fair values are recorded in other liabilities, subject to netting when master netting agreements are in place.

The nominal amount of derivatives designated as fair value hedging instruments equals the amortized cost of the AFS securities that are designated as being hedged for changes in foreign exchange rates.

In addition to the above, as at June 30, 2026 foreign denominated deposits of £227.5 million (December 31, 2025: £211.2 million); SGD0.1 million (December 31, 2025: SGD0.1 million) and Nil (December 31, 2025: CHF0.4 million) were designated as a hedge of foreign exchange risk associated with the net investment in foreign operations.

The Bank manages derivative exposure by monitoring the credit risk associated with each counterparty using counterparty specific credit risk limits, using master netting arrangements where appropriate and obtaining collateral. The Bank elected to offset in the consolidated balance sheets certain gross derivative assets and liabilities subject to netting agreements.

The Bank also elected not to offset certain derivative assets or liabilities and all collateral received or paid that the Bank or the counterparties could legally offset in the event of default. In the tables below, these positions are deducted from the net fair value presented in the consolidated balance sheets in order to present the net exposures. The collateral values presented in the following table are limited to the related net derivative asset or liability balance and, accordingly, do not include excess collateral received or paid.

Note 14: Fair value measurements

The following table presents the financial assets and liabilities that are measured at fair value on a recurring basis. Management classifies these items based on the type of inputs used in their respective fair value determination as described in Note 2 of the Bank's audited financial statements for the year ended December 31, 2025.

Management reviews the price of each security monthly, comparing market values to expectations and to the prior month’s price. Management's expectations are based upon knowledge of prevailing market conditions and developments relating to specific issuers and/or asset classes held in the investment portfolio. Where there are unusual or significant price movements, or where a certain asset class has performed out-of-line with expectations, the matter is reviewed by management.

Financial instruments in Level 1 include US Government Treasury notes.

Financial instruments in Level 2 include government debt securities, mortgage-backed securities, forward foreign exchange contracts and securities sold under agreements to repurchase.

There were no Level 3 investments as at June 30, 2026 and December 31, 2025.

There were no transfers between Level 1 and Level 2 or Level 2 and Level 3 during the six months ended June 30, 2026 and the year ended December 31, 2025.

Note 15: Long-term debt

On June 11, 2020, the Bank issued US $100 million of Subordinated Lower Tier II capital notes. The notes were issued at par and due on June 15, 2030. The issuance was by way of a registered offering with US institutional investors. The notes were listed on the BSX in the specialist debt securities category. The proceeds of the issue were used, among others, to repay the entire amount of the US $45 million outstanding subordinated notes Series 2005-B which matured on July 2, 2020. The notes issued paid a fixed coupon of 5.25% until June 15, 2025 when they became redeemable in whole at the option of the Bank. The notes were priced at a spread of 4.43% over the 10-year US Treasury yield. The Bank incurred $2.3 million of costs directly related to the issuance of these capital notes which were capitalized directly against the carrying value of these notes on the balance sheet and amortized over the life of the notes. These notes were redeemed at face value in June 2025 at which time, unamortized issuance costs were fully recognized in the Consolidated Statements of Operations as part of the expense.

No interest was capitalized during the six months ended June 30, 2026, and the year ended December 31, 2025.

Note 16: Earnings per share

Earnings per share have been calculated using the weighted average number of common shares outstanding during the period after deduction of the shares held as treasury stock. The dilutive effect of share-based compensation plans was calculated using the treasury stock method, whereby the proceeds received from the exercise of share-based awards are assumed to be used to repurchase outstanding shares, using the average market price of the Bank’s shares for the period. Numbers of shares are expressed in thousands.

During the six months ended June 30, 2026, the average number of outstanding awards of unvested common shares was 1.8 million (June 30, 2025: 1.8 million). Only awards for which the sum of 1) the expense that will be recognized in the future (i.e., the unrecognized expense) and 2) its exercise price, if any, was lower than the average market price of the Bank‘s common shares were considered dilutive and, therefore, included in the computation of diluted earnings per share.

An award's unrecognized expense is also considered to be the proceeds the employees would need to pay to purchase accelerated vesting of the awards. For the purposes of calculating dilution, such proceeds are assumed to be used by the Bank to buy back common shares at the average market price. The weighted-average number of outstanding awards, net of the assumed weighted-average number of common shares bought back, is included in the number of diluted participating shares.

Note 17: Share-based payments

The common shares transferred to employees under all share-based payments are either taken from the Bank's common treasury shares or from newly issued shares. All share-based payments are settled by the ultimate parent company which, pursuant to Bermuda law, is not taxed on income. There are no income tax benefits in relation to the issue of such shares as a form of compensation.

In May 2020, the Board of Directors approved the 2020 Omnibus Plan (the "2020 Plan"). Under the 2020 Plan, 3.0 million shares are initially available for grant to employees in the form of stock options or unvested share awards. In February 2025, the Board of Directors approved the Amended and Restated 2020 Omnibus Share Incentive Plan with 5.0 million additional shares available for grant to employees in the form of stock options or unvested share awards. Both types of awards are detailed below.

Stock Option Awards

Under the 2020 Plan, options can be awarded to Bank employees and executive management, based on predetermined vesting conditions that entitle the holder to purchase one common share at a subscription price no less than the price of the most recently traded common share when granted and have a maximum term of 10 years.

There were no stock options outstanding as at June 30, 2026 and December 31, 2025.

Unvested Share Awards

Recipients of unvested share awards are entitled to the related common shares at no cost, at the time the award vests. Recipients of unvested shares may be entitled to receive additional unvested shares having a value equal to the cash dividends that would have been paid had the unvested shares been issued and vested. Such additional unvested shares granted as dividend equivalents are subject to the same vesting schedule and conditions as the underlying unvested shares.

Unvested shares subject only to the time vesting condition generally vest upon retirement, death, disability or upon termination, by the Bank, of the holder’s employment unless if in connection with the holder’s misconduct. Unvested shares subject to both time vesting and performance vesting conditions remain outstanding and unvested upon retirement and will vest only if the performance conditions are met. Unvested shares can also vest in limited circumstances and if specifically approved by the Board, as stipulated in the holder’s employment contract. In all other circumstances, unvested shares are generally forfeited when employment ends.

The grant date weighted average fair value (which equals the actual trading price prevailing on grant date) of unvested share awards granted in the six months ended June 30, 2026 was $52.54 per share (December 31, 2025: $37.50 per share). The Bank expects to settle these awards by issuing new shares.

Employee Deferred Incentive Program

Under the Bank’s EDIP, shares are awarded to Bank employees and executive management based on the time vesting condition, which states that the shares will vest equally over a three-year period from the effective grant date.

Employee Long-Term Incentive Share Program

Under the Bank’s ELTIP, performance shares as well as time-vesting shares were awarded to employees and executive management. The performance shares will generally vest upon the achievement of certain performance targets in the three-year period from the effective grant date. The time-vesting shares will generally vest over the three-year period from the effective grant date.

Employee Share Purchase Plan

The Bank's ESPP was approved in July 2021 and registered in November 2021. The first offering period started in May 2022. Under the Bank's ESPP, eligible employees may elect to contribute up to 15% of their regular compensation toward the purchase of the Bank's shares at a 10% discount from market price on the closing date of each offering period. The ESPP specifies two consecutive six month offering periods per year. In the case of termination of employment or voluntary partial or full withdrawal from the plan, the related current offering period ESPP contributions are refunded to the employee and thus cannot be used to purchase shares under the ESPP. During the six months ended June 30, 2026, 5,128 shares (December 31, 2025: 13,022 shares) were issued under the ESPP.

Liabilities assumed
Other liabilities						(1,946)
Total liabilities assumed						(1,946)

The Bank incurred legal and professional transaction expenses related to this acquisition amounting to $1.0 million, all of which has been expensed and presented in the Consolidated Statements of Operations during the six months ended June 30, 2026.

For the period beginning on April 15, 2026 (i.e. acquisition date) to June 30, 2026, the amount of revenues and net income relating to the acquired R&H Guernsey operations that were not inextricably merged into the Bank’s operations were $2.5 million and a net income of $0.4 million, respectively.

CIBC Caribbean Acquisition

On May 28, 2026, the Bank announced that it has entered into an agreement to acquire Canadian Imperial Bank of Commerce's ("CIBC") 91.7% interest in CIBC Caribbean Bank Limited (“CIBC Caribbean”). The combined entity would have approximately $29 billion in assets.

The total consideration to be paid for 100% of CIBC Caribbean' shares (i.e. shares held by CIBC and shares held by minority shareholders on the acquisition date, if any) will be comprised of $1,091 million in cash and $703 million in Butterfield shares valued by reference to Butterfield’s 10-day NYSE volume-weighted average price of $55.66 as of May 27, 2026, for an aggregate purchase price of $1,794 million, or $1.14 per CIBC Caribbean share.

In connection with the transaction, Butterfield has obtained commitments for $700 million of Tier 2 capital-qualifying subordinated debt financing which is expected to be raised prior to closing.

The transaction is expected to close in the first half of 2027, subject to receipt of Butterfield shareholder and regulatory approvals and the satisfaction of customary closing conditions. Following the transaction, Butterfield’s ordinary shares will continue to be listed on the NYSE and the BSX, and Butterfield intends to undertake additional secondary share listings on the Barbados Stock Exchange, the Bahamas International Securities Exchange, and the Trinidad & Tobago Stock Exchange, subject to local listing and regulatory requirements.

Following completion of the transaction, CIBC will own an approximately 22% stake in the combined entity. Under the terms of Butterfield and CIBC’s shareholder agreement, CIBC will then initially have the right to appoint two directors to Butterfield’s Board. The shareholder agreement will also provide for certain lockup restrictions with respect to CIBC’s stake in Butterfield, and include customary standstill obligations and registration rights.
