Forward-looking statements are not historical facts and include statements with respect to, among other things, our beliefs, plans, objectives, goals, expectations, anticipations, assumptions, estimates, intentions, and future performance, including, without limitation, statements regarding the proposed acquisition of CIBC Caribbean by Bank of N.T. Butterfield & Son Limited (“Butterfield”); the expected timing, structure, terms and completion of the proposed transaction; the expected form and mix of consideration, including the issuance of Butterfield ordinary shares; any acquisition of shares from minority shareholders of CIBC Caribbean or related compulsory acquisition, squeeze-out or similar process; the expected ownership, governance, management, capital, regulatory and operating profile of Butterfield following the proposed transaction; the expected financing of the proposed transaction, including the amount, terms and timing of the proposed subordinated debt financing; the anticipated benefits of the proposed transaction, including expected scale, diversification, cost savings, synergies, earnings accretion, tangible book value per share accretion, capital generation, regulatory capital ratios, risk-weighted assets, liquidity, deposit mix, market position and other financial and operating impacts; and other forecasts, targets, projections and estimates included in this presentation. Forward-looking statements involve known and unknown risks, uncertainties and other factors, many of which are beyond Butterfield’s control, which may cause the actual results, performance, capital, ownership, financial condition or achievements of Butterfield to be materially different from future results, performance, capital, ownership, financial condition or achievements expressed or implied by such forward-looking statements. These risks and uncertainties include, among others: Butterfield’s ability to successfully complete the proposed acquisition of CIBC Caribbean on the anticipated terms or timeline or at all; Butterfield’s ability to realize the anticipated benefits of the proposed transaction in the expected timeframes or at all, including cost savings, synergies, balance sheet and capital optimization initiatives, earnings accretion, and tangible book value per share accretion; Butterfield’s ability to successfully integrate CIBC Caribbean’s businesses, operations, systems, controls, compliance programs, risk management framework, personnel and culture into those of Butterfield; the risk that such integration may be more difficult, time-consuming or costly than expected; the failure of any of the conditions to the proposed transaction to be satisfied or waived; the failure to obtain required shareholder, regulatory, governmental, securities exchange, exchange-control or other approvals, or delays in obtaining such approvals; the risk that such approvals may result in the imposition of conditions, restrictions or requirements that could materially adversely affect Butterfield, CIBC Caribbean or the expected benefits of the proposed transaction or that any proposed conditions, restrictions or requirements or other actions of regulatory or governmental bodies or securities exchanges could delay or prevent the closing of the proposed transaction; the risk that any minority shareholder offer, compulsory acquisition, squeeze-out or similar process is delayed, not completed or completed on different terms than expected; revenues following the proposed transaction being lower than expected; operating costs, customer loss and business disruption, including difficulties in maintaining relationships with employees, customers, clients, depositors, vendors, suppliers, regulators and other business partners, being greater than expected; risks associated with the disruption of management’s attention from Butterfield’s ongoing business operations due to the proposed transaction; reputational risks and potential adverse reactions to the announcement, pendency or completion of the proposed transaction; the outcome of any legal, regulatory or shareholder proceedings, inquiries or investigations that may be instituted or arise in connection with the proposed transaction; the possibility that the proposed transaction may be more expensive to complete than anticipated, including as a result of unexpected transaction, integration, restructuring, financing, litigation, regulatory, tax, accounting or other costs; dilution caused by the issuance of additional Butterfield ordinary shares in connection with the proposed transaction; changes in Butterfield’s share price, interest rates, foreign exchange rates, capital markets or other market conditions that may affect the transaction financing or expected financial impacts of the proposed transaction; the risk that any subordinated debt or other transaction financing is not obtained on the expected terms, timing or at all; and the risk that assumptions underlying pro forma financial information, purchase accounting, credit marks, fair value marks, integration costs, cost savings, synergies, capital ratios, earnings accretion, tangible book value per share accretion, return metrics and other financial impacts prove to be inaccurate. Other factors that may impact Butterfield’s future results, performance, financial condition or achievements include worldwide and regional economic conditions, including economic growth and general business conditions in Bermuda, the Cayman Islands, Barbados, The Bahamas, Turks and Caicos, Trinidad and Tobago, the broader Atlantic, Caribbean and other markets in which Butterfield or CIBC Caribbean operates; fluctuations in interest rates, inflation, monetary policy, foreign exchange rates, capital markets, tourism, real estate markets and sovereign credit ratings, including a decline in Bermuda’s sovereign credit rating; any sudden liquidity crisis; changes in customer behavior, including customer borrowing, repayment, investment and deposit practices; unfavorable developments concerning asset quality, credit quality, loan losses, non- performing loans, collateral values, loan concentrations, sovereign exposures, residential mortgage risk weighting, reserves, funding costs, liquidity and deposit flows; competitive product and pricing pressures; security risks, including cybersecurity, data privacy, fraud, financial crime, anti-money laundering and sanctions risks; the impact, extent and timing of technological changes, systems conversions and operational resilience initiatives; risks relating to the success of Butterfield’s updated systems and platforms; capital management activities; changes in laws, regulations, accounting standards, tax laws, regulatory capital or liquidity requirements and supervisory expectations; potential impacts of climate change, hurricanes and other natural disasters; compliance with regulatory requirements; and other factors.

All forward-looking statements in this presentation are expressly qualified in their entirety by this cautionary notice, including, without limitation, the risks and uncertainties described in our reports and filings filed with the Securities and Exchange Commission (“SEC”), including under the caption “Risk Factors” in our most recent Form 20-F and in any subsequent reports furnished or filed with the SEC.

3 About Non-GAAP Financial Measures This presentation contains non-GAAP financial measures, including “core” net income and other financial measures presented on a “core” basis, tangible common equity and related measures including tangible common equity to tangible assets ratio, and run rate earnings. We believe such measures provide useful information to investors that is supplementary to our financial condition, results of operations and cash flows computed in accordance with GAAP; however, our non-GAAP financial measures have a number of limitations. 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 the historical non-GAAP measures to corresponding GAAP financial measures are provided in the Appendix of this presentation. To the extent this presentation includes forecasts using non-GAAP financial measures, including run rate earnings, Butterfield is unable to provide reconciliations to the most directly comparable GAAP financial measures without unreasonable efforts because certain information necessary to prepare such reconciliations depends on future events and cannot be reasonably estimated. Such unavailable information may include purchase accounting adjustments, integration costs and other items that may significantly affect reported GAAP results. Presentation of Financial Information This presentation includes certain combined historical financial information relating to the proposed acquisition of CIBC Caribbean, including total assets and total deposits. This presentation also includes certain combined forecast financial information relating to the proposed transaction, including tangible common equity and run rate earnings. The combined financial information has been prepared solely for illustrative purposes to assist investors in understanding certain anticipated effects of the proposed transaction and is based on assumptions and estimates that Butterfield believes are reasonable. The combined financial information does not purport to reflect what Butterfield’s financial position or results of operations would have been had the proposed transaction occurred on the dates assumed, nor is it necessarily indicative of Butterfield’s future financial position or results of operations following completion of the proposed transaction. The combined forecast financial information, including tangible common equity and run rate earnings, reflects management’s current expectations and assumptions regarding the proposed transaction and its anticipated benefits. Such forecasts are inherently uncertain and actual results may differ materially from those reflected in the forecast financial information. The combined financial information included in this presentation does not purport to comply with Article 11 of Regulation S-X and should not be viewed as a substitute for pro forma financial information prepared in accordance with Article 11 of Regulation S-X. Certain monetary amounts, percentages and other figures included in this presentation have been subject to rounding adjustments. Accordingly, figures shown as totals in certain tables may not be the arithmetic aggregation of the figures that precede them, figures expressed as percentages in the text may not total 100% or, as applicable, when aggregated may not be the arithmetic aggregation of the percentages that precede them.
