2 Forward-Looking Statements Forward-Looking Statements: Certain of the statements made in this presentation are forward-looking statements within the meaning of the U.S. Private Securities Litigation Reform Act of 1995. Forward-looking statements include statements with respect to our beliefs, plans, objectives, goals, expectations, anticipations, assumptions, estimates, intentions, and future performance, including, without limitation, our intention to, identify and enter into acquisitions or other strategic transactions and the timing and anticipated benefits thereof (including with respect to the acquisition of R&H Guernsey), and involve known and unknown risks, uncertainties and other factors, which may be beyond our control. These risks and uncertainties may cause the actual results, performance, capital, ownership or achievements of Butterfield to be materially different from future results, performance or achievements expressed or implied by such forward-looking statements due to a variety of factors, including Butterfield’s ability to realize the anticipated benefits of the acquisition of R&H Guernsey in the expected time-frames or at all; Butterfield’s ability to successfully integrate R&H Guernsey’s operations into those of Butterfield; the risk that such integration may be more difficult, time-consuming or costly than expected; the risk that revenues following the acquisition of R&H Guernsey may be lower than expected; the risk that operating costs, customer loss and business disruption (including, without limitation, difficulties in maintaining relationships with employees, customers, clients or suppliers) may be greater than expected following the acquisition; risks associated with the disruption of management’s attention from ongoing business operations due to the acquisition; and the outcome of any legal proceedings that may be instituted against Butterfield or R&H Guernsey. Other factors that may impact Butterfield’s future results, performance or achievements include worldwide economic conditions (including economic growth and general business conditions) and fluctuations of interest rates, inflation, a decline in Bermuda’s sovereign credit rating, any sudden liquidity crisis, the successful entry into, completion and integration of acquisitions or the realization of the anticipated benefits of such acquisitions, success in business retention (including the retention of relationships associated with our acquisition of R&H Guernsey), potential impacts of climate change, the success of our updated systems and platforms and other factors. Forward-looking statements can be identified by words such as "anticipate," "assume," "believe," "estimate," "expect," "indicate," "intend," "may," "plan," "point to," "predict," "project," "seek," "target," "potential," "will," "would," "could," "should," "continue," "contemplate" and other similar expressions, although not all forward-looking statements contain these identifying words. All statements other than statements of historical fact are statements that could be forward-looking statements. All forward-looking statements in this disclosure are expressly qualified in their entirety by this cautionary notice, including, without limitation, those risks and uncertainties described in our SEC reports and filings, including under the caption "Risk Factors" in our most recent Form 20-F. Such reports are available upon request from Butterfield, or from the Securities and Exchange Commission ("SEC"), including through the SEC’s website at https://www.sec.gov. Any forward-looking statements made by Butterfield are current views as at the date they are made. Except as otherwise required by law, Butterfield assumes no obligation and does not undertake to review, update, revise or correct any of the forward-looking statements included in this disclosure, whether as a result of new information, future events or other developments. You are cautioned not to place undue reliance on the forward-looking statements made by Butterfield in this disclosure. Comparisons of results for current and any prior periods are not intended to express any future trends or indications of future performance, and should only be viewed as historical data. 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. 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 these non-GAAP measures to corresponding GAAP financial measures are provided in the Appendix of this presentation. Presentation of Financial Information: 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, and 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.
