Hamilton, Bermuda - April 23, 2025: The Bank of N.T. Butterfield & Son Limited ("Butterfield" or the "Bank") (BSX: NTB.BH; NYSE: NTB) today announced financial results for the quarter ended March 31, 2025.

Net income for the first quarter of 2025 was $53.8 million, or $1.23 per diluted common share, compared to net income of $59.6 million, or $1.34 per diluted common share, for the previous quarter and $53.4 million, or $1.13 per diluted common share, for the first quarter of 2024. Core net income1 for the first quarter of 2025 was $56.7 million, or $1.30 per diluted common share, compared to $59.6 million, or $1.34 per diluted common share, for the previous quarter and $55.0 million, or $1.17 per diluted common share, for the first quarter of 2024.

The return on average common equity for the first quarter of 2025 was 20.9% compared to 22.9% for the previous quarter and 21.5% for the first quarter of 2024. The core return on average tangible common equity1 for the first quarter of 2025 was 24.2%, compared to 25.2% for the previous quarter and 24.5% for the first quarter of 2024. The efficiency ratio for the first quarter of 2025 was 61.8%, compared to 58.2% for the previous quarter and 60.9% for the first quarter of 2024. The core efficiency ratio1 for the first quarter of 2025 was 59.8% compared with 58.2% in the previous quarter and 59.8% for the first quarter of 2024.

Michael Collins, Butterfield's Chairman and Chief Executive Officer, commented, “Our strong performance in the first quarter of 2025 continued to demonstrate the resilience of our balance sheet with an expanding net interest margin, higher net interest income, stable core efficiency and effective capital management. We remain committed to managing Butterfield for the long-term benefit of our clients and communities, while creating value for shareholders across more pronounced economic and interest rate cycles.”

Net income and core net income1 were down in the first quarter of 2025 versus the prior quarter. Net income was down in the first quarter of 2025 compared to the prior quarter primarily due to lower non-interest income from banking services with higher non-interest expenses due to the impact of a group-wide voluntary early retirement program executed during the quarter offset by higher net interest income and lower allowance for credit losses. Core net income1 was down in the first quarter of 2025 primarily due to lower non-interest income from banking services offset by higher net interest income and lower allowance for credit losses and non-interest expenses.

Net interest income (“NII”) for the first quarter of 2025 was $89.3 million, or $0.7 million higher compared with NII of $88.6 million in the previous quarter and $2.2 million higher from $87.1 million in the first quarter of 2024. NII was higher during the first quarter of 2025 compared to the previous quarter and first quarter of 2024, primarily due to a lower cost of deposits driven by a positive mix shift in deposits to demand from term and higher yields on investments as fixed rate investments continued to reprice. These were partially offset by lower yields on loan and treasury assets following interest rate cuts by central banks during the fourth quarter of 2024, as well as a lower day count in the first quarter of 2025 compared to the fourth quarter of 2024.

Net interest margin (“NIM”) for the first quarter of 2025 was 2.70%, an increase of 9 basis points from the previous quarter at 2.61% and up 2 basis points from 2.68% in the first quarter of 2024. NIM in the first quarter of 2025 increased compared to the prior quarter and first quarter of 2024 due to a lower cost of deposits, partially offset by a lower volume of interest earning assets in the previous quarter in addition to the asset yield dynamics noted above.

Non-interest income for the first quarter of 2025 was $58.4 million, a decrease of $4.8 million from $63.2 million in the previous quarter and $3.3 million higher than $55.1 million in the first quarter of 2024. The decrease in the first quarter of 2025 compared to the prior quarter was due to lower card volume due to seasonality and lower third party volume incentives offset by higher foreign exchange volume, trust income and asset management fees. Non-interest income in the first quarter of 2025 was higher than the first quarter of 2024 primarily due to higher card volume, and increases in asset management fees, foreign exchange volume and trust fees.

Non-interest expenses were $93.2 million in the first quarter of 2025, compared to $90.6 million in the previous quarter and $88.5 million in the first quarter of 2024. Core non-interest expenses1 of $90.3 million in the first quarter of 2025 were comparable to the $90.6 million incurred in the previous quarter and higher than the $86.9 million incurred in the first quarter of 2024. Core non-interest expenses1 in the first quarter of 2025 were higher compared to the first quarter of 2024 due to higher salary and other employee benefits, seasonally higher payroll taxes and increased marketing expenses. Included in salaries and other employee benefits are non-core expenses of $2.9 million which relates to costs arising from a group-wide voluntary early retirement program executed in the first quarter of 2025.

Period end deposit balances were $12.6 billion, a decrease of 1.1% compared to $12.7 billion at December 31, 2024, primarily due to deposit decreases in Bermuda which were partially offset by increases in the Channel Islands and UK segment due principally to a weaker US dollar. Average deposits were $12.5 billion in the quarter ended March 31, 2025, which is consistent with the prior quarter.

Tangible book value per share at the end of the first quarter of 2025 is $22.94 per share, higher than $21.70 per share at the end of the prior quarter and an increase over the $19.45 at the end of the first quarter of 2024.

Butterfield maintained its balanced capital return policy. The Board again declared a quarterly dividend of $0.44 per common share to be paid on May 21, 2025 to shareholders of record on May 7, 2025. During the first quarter of 2025, Butterfield repurchased 1.1 million common shares under the Bank's existing share repurchase program.

Effective January 1, 2025, the Bank has adopted the Basel Committee on Banking Supervision's ("BCBS") revised standardized approach for credit risk framework as required by the Bermuda Monetary Authority ("BMA"). Comparatives were prepared under the prior credit risk framework. The current total regulatory capital ratio as at March 31, 2025 was 27.7% , compared to 25.8% as at December 31, 2024. Both of these ratios remain conservatively above the minimum regulatory requirements applicable to the Bank.

QUARTER ENDED MARCH 31, 2025 COMPARED WITH THE QUARTER ENDED DECEMBER 31, 2024

Net Income

Net income for the quarter ended March 31, 2025 was $53.8 million, down from $59.6 million in the prior quarter.

The $5.8 million change in net income during the quarter ended March 31, 2025 compared to the previous quarter is attributable to the following:

•$4.8 million decrease in non-interest income driven by (i) $6.1 million decrease in banking fees due to prior period seasonality; offset by (ii) $0.4 million increase in foreign exchange revenue driven by volume; (iii) $0.6 million increase in trust revenue due to new annual fees for an expanded service mandate; and (iv) $0.4 million increase in asset management fees due to higher brokerage commissions based on increased client activity;

•$0.7 million increase in net interest income before provision for credit losses driven by a lower cost of deposits due to a positive mix shift in deposits to demand from term and higher investment yields, as fixed rate investments continued to reprice, partially offset by lower loan and treasury yields and lower loan volumes;

•$0.7 million decrease in provision for credit losses driven by a release related to a commercial real estate facility in Bermuda and partially offset by a provision on a residential mortgage relationship in the Channel Islands and UK segment; and

•$2.6 million increase in non-interest expenses driven by (i) $1.8 million increase in salaries and other employee benefits expenses due to costs recognized related to the group-wide voluntary early retirement program executed during the quarter and the impact of annual promotions and salary reviews offset by better-than-expected staff healthcare costs; (ii) $1.2 million increase in payroll taxes related to the annual vesting of share compensation; (iii) $0.8 million increase in other expenses driven by a provision for a potential legal settlement; and partially offset by (iv) $0.6 million decrease in technology and communication due to lower technology services and corporate travel costs; and (v) $0.6 million decrease in marketing due to event costs and sponsorship incurred in the prior quarter.

Non-Core Items1

Non-core items resulted in expenses, net of gains, of $2.9 million for the first quarter of 2025. Non-core items for the quarter relate mainly to costs recognized related to the group-wide voluntary early retirement program.

Management does not believe that comparative period expenses, gains or losses identified as non-core are indicative of the results of operations of the Bank in the ordinary course of business.

BALANCE SHEET COMMENTARY AT MARCH 31, 2025 COMPARED WITH DECEMBER 31, 2024

Total Assets

Total assets of the Bank were $14.0 billion at March 31, 2025, a decrease of $0.2 billion from December 31, 2024. The Bank maintained a highly liquid position at March 31, 2025, with $9.0 billion of cash, bank deposits, reverse repurchase agreements and liquid investments representing 64.5% of total assets, compared with 65.3% at December 31, 2024.

Loans Receivable

The loan portfolio totaled $4.5 billion at March 31, 2025, which was consistent with the December 31, 2024 balances.

The allowance for credit losses at March 31, 2025 totaled $25.3 million, a decrease of $0.4 million from $25.7 million at December 31, 2024.

The loan portfolio represented 32.2% of total assets at March 31, 2025 (December 31, 2024: 31.4%), while loans as a percentage of total deposits was 35.8% at March 31, 2025 (December 31, 2024: 35.1%). The increase in both ratios was attributable principally to an increase in loan balances, primarily driven by foreign exchange translation, and a decrease in total deposits at March 31, 2025 compared to December 31, 2024.

As at March 31, 2025, the Bank had gross non-accrual loans of $103.8 million, representing 2.3% of total gross loans, an increase of $27.1 million from $76.7 million, or 1.7% of total loans, at December 31, 2024. The increase in non-accrual loans was driven by a residential mortgage facility in the Channels Islands and UK segment.

Reconciliation of US GAAP Results to Core Earnings

The table below shows the reconciliation of net income in accordance with US GAAP to core earnings, a non-GAAP measure, which excludes certain significant items that are included in our US GAAP results of operations. We focus on core net income, which we calculate by adjusting net income to exclude certain income or expense items that are not representative of our business operations, or “non-core”. Core net income includes revenue, gains, losses and expense items incurred in the normal course of business. We believe that expressing earnings and certain other financial measures excluding these non-core items provides a meaningful base for period-to-period comparisons, which management believes will assist investors in analyzing the operating results of the Bank and predicting future performance. We believe that presentation of these non-GAAP financial measures will permit investors to assess the performance of the Bank on the same basis as management.

(In thousands of US dollars, unless otherwise stated)

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 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, 2024.

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.

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

•Employee benefit plans

New Accounting Pronouncements

There were no accounting developments issued during the three months ended March 31, 2025 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.

Amortized<br> cost Gross<br> unrealized<br> gains Gross<br> unrealized<br> losses Fair value Amortized<br> cost Gross<br> unrealized<br> gains Gross<br> unrealized<br> losses Fair value

Total held-to-maturity 3,184,912 59 (507,003) 2,677,968 3,240,290 (569,250) 2,671,040

¹For the three months ended March 31, 2025 and March 31, 2024, 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 March 31, 2025, comprising 171 securities representing 69.4% of the AFS portfolios' carrying value (December 31, 2024: 184 and 87.7%), represent credit losses. Total gross unrealized AFS losses were 8.7% of the fair value of the affected securities (December 31, 2024: 8.3%).

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 Model ("CECL") model. HTM debt securities that were in an unrealized loss position as of March 31, 2025, were comprised of 218 securities representing 98.8% of the HTM portfolios’ carrying value (December 31, 2024: 220 and 100%). Total gross unrealized HTM losses were 19.2% of the fair value of affected securities (December 31, 2024: 21.3%).

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.

Management believes that all the Non-US governments debt securities do not have any credit losses, given the explicit guarantee provided by the issuing government.

Investments in Asset-backed securities - Student loans are composed of securities collateralized by Federal Family Education Loan Program ("FFELP") loans. FFELP loans benefit from a US federal government guarantee of at least 97% of defaulted principal and accrued interest, with additional credit support provided in the form of over-collateralization, subordination and excess spread, which collectively total in excess of 100%. Accordingly, the vast majority of FFELP loan-backed securities are not exposed to traditional consumer credit risk.

Investments in Residential mortgage-backed securities relate to 13 securities (December 31, 2024: 13) which are rated AAA and possess similar significant credit enhancement as described above. 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 43.4% - 52.2%, 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 March 31, 2025 is 6.16% (December 31, 2024: 6.29%). The interest receivable on total loans as at March 31, 2025 is $16.3 million (December 31, 2024: $8.0 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 Bank also has a Group Provisions and Impairments Committee which is responsible for approving significant provisions 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

Allowance for expected credit losses decreased during the three months ended March 31, 2025 driven by a release related to a commercial real estate facility in Bermuda and partially offset by a provision on a residential mortgage facility in the Channel Islands and UK segment. As disclosed in Note 2 of the December 31, 2024 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 three months ended March 31, 2025, no interest was recognized on non-accrual loans. No credit deteriorated loans were purchased during the period.

As at March 31, 2025 and March 31, 2024, all loans for which a concession was granted during the preceding 12 months are current, except for the following:

Commercial mortgages:

–Nil (March 31, 2024: $0.5 million) of commercial mortgages for which a term extension and reduction in interest rate was granted are 60 to 89 days past due.

Residential mortgage loans:

–$1.2 million (March 31, 2024: $0.1 million) of residential mortgage loans for which a reduction in interest rate was granted are 30 to 59 days past due;

–$0.2 million (March 31, 2024: Nil) of residential mortgage loans for which a reduction in interest rate was granted are 60 to 89 days past due; and

–$0.2 million (March 31, 2024: $0.8 million) of residential mortgage loans for which a reduction in interest rate was granted had a payment default 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.

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 March 31, 2025, $132.4 million (December 31, 2024: $138.4 million) of standby letters of credit were issued under this facility.

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.

Repurchase agreements

The Bank utilizes repurchase agreements and resell agreements (reverse repurchase agreements) to manage liquidity that 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 March 31, 2025, the Bank had 7 open positions (December 31, 2024: 15) in resell agreements with a remaining maturity of less than 120 days involving pools of mortgages issued by US federal agencies and Non-US government debt securities.The carrying value of these resell agreements is $0.7 billion (December 31, 2024: $1.2 billion) and are included in securities purchased under agreements to resell on the consolidated balance sheets. As at March 31, 2025, there were no positions (December 31, 2024: no positions) which were offset on the consolidated balance sheets to arrive at the carrying value, and there was no collateral amount which was available to offset against the future settlement amount.

As at March 31, 2025, the Bank had zero open position (December 31, 2024: one) in a repurchase agreement with a remaining maturity of less than 30 days involving one Non-US government debt securities, with the carrying value of the repurchase agreement being nil (December 31, 2024:$92.6 million).

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, except as noted in the following paragraph.

As publicly announced, in November 2013, the US Attorney’s Office for the Southern District of New York applied for and secured the issuance of so-called John Doe Summonses to six US financial institutions with which the Bank had correspondent bank relationships in connection with a US cross border tax investigation. On August 3, 2021, the Bank announced it had reached a resolution with the United States Department of Justice concerning this inquiry. The resolution is in the form of a non-prosecution agreement with a three-year term which concluded in July 2024. The Bank paid $5.6 million in respect of Forfeiture and Tax Restitution Amounts which is consistent with that previously provisioned for.

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 2038. 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. Each reportable segment has a managing director who 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, 2024. 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.

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

(In thousands of US dollars, unless otherwise stated)

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 Association ("ISDAs"). 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.

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 20: 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.

In addition to the above, as at March 31, 2025 foreign denominated deposits of £194.8 million (December 31, 2024: £277.1 million); SGD1.6 million (December 31, 2024: SGD 1.5 million) and CHF0.4 million (December 31, 2024: CHF0.4 million) were designated as a hedge of foreign exchange risk associated with the net investment in foreign operations.

We manage 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, 2024.

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 and UK Government Treasury notes.

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

There were no Level 3 investments as at March 31, 2025 and December 31, 2024.

There were no transfers between Level 1 and Level 2 or Level 2 and Level 3 during the three months ended March 31, 2025 and the year ended December 31, 2024.

Note 15: Interest rate risk

The following tables set out the assets, liabilities and shareholders' equity on the date of the earlier of contractual maturity, expected maturity or repricing date. Use of these tables to derive information about the Bank’s interest rate risk position is limited by the fact that customers may choose to terminate their financial instruments at a date earlier than the contractual maturity or repricing date. Examples of this include fixed-rate mortgages, which are shown at contractual maturity but which may be subject to early prepayment, and certain term deposits, which are shown at contractual maturity but which may be withdrawn before their contractual maturity subject to prepayment penalties. Investments are shown based on remaining contractual maturities. The remaining contractual principal maturities for mortgage-backed securities (primarily US government agencies) do not consider prepayments. Remaining expected maturities will differ from contractual maturities because borrowers may have the right to prepay obligations before the underlying mortgages mature.

Note 16: 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 are 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 pay a fixed coupon of 5.25% until June 15, 2025 when they become 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. These costs have been capitalized directly against the carrying value of these notes on the balance sheet, and will be amortized over the life of the notes.

No interest was capitalized during the three months ended March 31, 2025, and the year ended December 31, 2024.

The following table presents the contractual maturity and interest payments for long-term debt issued by the Bank as at March 31, 2025. The interest payments are calculated until contractual maturity using the Secured Overnight Financing Rate ("SOFR") as outlined below.

Note 17: 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 three months ended March 31, 2025, the average number of outstanding awards of unvested common shares was 1.8 million (March 31, 2024: 1.5 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 18: 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 thousands of US dollars, unless otherwise stated)

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

2020 Plans

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 March 31, 2025 and December 31, 2024.

Share-Based Incentive Programs

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 three months ended March 31, 2025 was $37.44 per share (December 31, 2024: $30.11 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 three months ended March 31, 2025, nil shares (December 31, 2024: 16,762 shares) were issued under the ESPP.

Note 19: Share repurchase programs

From time to time, the Bank may seek to repurchase and retire equity securities of the Bank, through cash purchase, privately negotiated transactions, or otherwise. Such transactions, if any, depend on prevailing market conditions, liquidity and capital requirements, contractual restrictions, and other factors.

Common Share Repurchase Program

On February 14, 2022, the Board approved a new common share repurchase program, authorizing the purchase of up to 2.0 million common shares through to February 28, 2023.

On February 13, 2023, the Board approved a new common share repurchase program, authorizing the purchase of up to 3.0 million common shares through to February 29, 2024.

On December 5, 2023, the Board approved a new common share repurchase program, authorizing the purchase of up to 3.5 million common shares through to December 31, 2024.

On July 22, 2024, the Board approved a new common share repurchase program, authorizing the purchase of up to 2.1 million common shares through to December 31, 2024.

On December 9, 2024, the Board approved a new common share repurchase program, authorizing the purchase of up to 2.7 million common shares through to December 31,

As such, investors should not view these disclosures as a substitute for results determined in accordance with GAAP, and they are not necessarily comparable to non-GAAP financial measures that other companies use. Reconciliations of these non-GAAP measures to corresponding GAAP financial measures are provided in the Appendix of this presentation.

These were partially offset by lower loan and treasury yields following rate cuts by central banks during the fourth quarter of 2024, coupled with lower day count in the first quarter of 2025 • Net interest margin (“NIM”) is higher at 2.70% compared to 2.61% in the prior quarter • Average loan volume was lower compared to the prior quarter as amortizations and paydowns outpaced originations (In US$ millions) Q1 2025 vs.Q4 2024 Avg.
