• Board declares dividend for the quarter ended September 30, 2021 of $0.44 pershare

Hamilton, Bermuda – October 27, 2021: The Bank of N.T. Butterfield & Son Limited (“Butterfield” or the “Bank”)(BSX: NTB.BH; NYSE: NTB) today announced financial results for the third quarter ended September 30, 2021.

Net income for the third quarter of 2021 was $39.8 million, or $0.80 per diluted common share, compared to net income of $39.6 million, or $0.79 per diluted common share, for the previous quarter and $30.5 million, or $0.61 per diluted common share, for the third quarter of 2020. Core net income1 for the third quarter of 2021 was $40.0 million, or $0.80 per diluted common share, compared to $40.1 million, or $0.80 per diluted common share, for the previous quarter and $36.5 million, or $0.73 per diluted common share, for the third quarter of 2020.

The core return on average tangible common equity1 for the third quarter of 2021 was 17.9%, compared to 18.7% for the previous quarter and 16.2% for the third quarter of 2020. The efficiency ratio for the third quarter of 2021 was 66.5%, compared to 67.4% from the previous quarter and 73.5% from the third quarter of 2020. The core efficiency ratio1 for the third quarter of 2021 was 66.3%, compared to 66.3% from the previous quarter and 68.0% from the third quarter of 2020.

Michael Collins, Butterfield’s Chairman and Chief Executive Officer, commented, “The third quarter of 2021 continued to illustrate the value of Butterfield’s business model across economic cycles. Our strong results were achieved despite the prevailing low interest rate environment and the continued waves of outbreaks of COVID-19. Butterfield has been able to maintain strong net interest earnings and non-interest revenue, with excellent credit quality and performance, while managing strategic business investments and prudent expense moderation initiatives. Our balance sheet remains strong and we continue to work with depositors to best serve their needs. With historically high deposits, we continuously evaluate deployment options into earnings assets, while maintaining appropriate capital, funding and liquidity levels.”

Net interest income (“NII”) for the third quarter of 2021 was $75.7 million, an increase of $1.0 million, compared with NII of $74.7 million in the previous quarter and up $0.4 million from $75.3 million in the third quarter of 2020. NII was higher during the third quarter of 2021 compared to the prior quarter and the third quarter of 2020 due to an increase in the average volume of interest earning assets, which offset slightly lower average yields.

Net interest margin (“NIM”) for the third quarter of 2021 was 1.97%, a decrease of 4 basis points from 2.01% in the previous quarter and down 33 basis points from 2.30% in the third quarter of 2020. NIM in the third quarter of 2021 was lower than the prior quarter and third quarter of 2020 primarily due to lower portfolio yields on investments and loans, as well as a one basis point increase in deposit costs versus the prior quarter.

Non-interest income for the third quarter of 2021 of $49.0 million was $0.2 million higher than the $48.8 million earned in the previous quarter and $2.1 million higher than $46.9 million in the third quarter of 2020. Continued increases in banking and foreign exchange fees contributed to the improvement in non-interest income.

Credit reserve releases were negligible for the third quarter of 2021 versus a release of $1.0 million in the previous quarter and a provision expense of $1.4 million during the third quarter of 2020. The lower recoveries of credit losses compared to the prior quarter were driven by improving macroeconomic forecasts.

Non-interest expenses were $84.4 million in the third quarter of 2021, compared to $84.8 million in the previous quarter and $91.3 million in the third quarter of 2020. Core non-interest expenses1 were $84.2 million in the third quarter of 2021, compared to $83.4 million in the previous quarter and $84.6 million in the third quarter of 2020. Non-interest expenses were elevated in the third quarter versus the second quarter of 2021 due to costs associated with new technology projects that went live during the third quarter and increased professional fees to support strategic initiatives and for legal advice relating to the resolution of the US Department of Justice inquiry.

Period end deposit balances increased to $13.9 billion from $13.3 billion as at December 31, 2020. Deposits remained higher across all jurisdictions as customers maintained elevated deposit balances, although lower than the prior quarter as economies continue to open and customers activate their savings.

The Bank continued its balanced capital return policy. The Board again declared a quarterly dividend of $0.44 per common share to be paid on November 24, 2021 to shareholders of record on November 10, 2021. During the third quarter of 2021, Butterfield also repurchased 0.1 million common shares under the Bank’s current 2.0 million common share repurchase plan authorization.

The current total regulatory capital ratio as at September 30, 2021 was 20.4% as calculated under Basel III, compared to 19.8% as at December 31, 2020. Both of these ratios remain significantly above the Basel III regulatory requirements applicable to the Bank.

As previously announced, during the quarter, the Bank has reached a resolution with the US Department of Justice concerning the inquiry into Butterfield’s legacy business with US clients that was first reported in November 2013. The resolution is in the form of a non-prosecution agreement with a three-year term. The Bank paid $5.6 million in respect of Forfeiture and Tax Restitution Amounts, in line with the provision that was included in the Bank’s financial statements as recorded in 2015 and 2016.

QUARTER ENDED SEPTEMBER 30, 2021 COMPARED WITH THE QUARTER ENDED JUNE 30, 2021

Net Income

In accordance with regulatory capital guidance, the Bank has elected to make use of transitional arrangements which allow the deferral of the January 1, 2020

Current Expected Credit Loss (“CECL”) impact of $7.8 million on its regulatory capital over a period of 5 years.

Net income for the quarter ended September 30, 2021 was $39.8 million, up $0.2 million from $39.6 million in the prior quarter.

The $0.2 million increase in net income in the quarter ended September 30, 2021 compared to the previous quarter was due principally to the following:

$1.2 million decrease in staff-related expenses mainly due to non-core redundancy costs associated with the transfer of Channel Islands banking operations from Mauritius to Butterfield’s service center in Canada and Guernsey recorded in the previous quarter;

$1.3 million increase in net interest income before provision for credit losses, driven by a $0.9 million increase in interest income from investments and banks as a result of the redeployment of funds from cash due from banks and a $0.4 million increase in loan interest income due to increased average loan balances in the quarter;

$1.0 million decrease in recoveries of credit losses driven by sequential lower incremental improvements inmacroeconomic forecasts impacting future expected credit loss estimates;

$0.6 million increase in technology and communications costs due to new technology projects that went liveduring the quarter; and resolution of the US Department of Justice inquiry.

$0.8 million increase in professional fees to support strategic initiatives and for legal advice relating to the resolution of the US Department of Justice inquiry.

Non-Core Items1

Non-core items resulted in a net expense of $0.2 million in the third quarter of 2021. Non-core items for the period were incurred in relation to professional fees and final settlement of the US Department of Justice inquiry which commenced in 2013.

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 SEPTEMBER 30, 2021 COMPARED WITH DECEMBER 31, 2020

Total Assets

Total assets of the Bank were $15.3 billion at September 30, 2021, an increase of $0.6 billion from December 31, 2020. The Bank maintained a highly liquid position at September 30, 2021, with its $9.7 billion of cash and demand deposits with banks, reverse repurchase agreements and liquid investments representing 63.5% of total assets, compared with 62.2% at December 31, 2020.

Loans Receivable

The loan portfolio totaled $5.2 billion at September 30, 2021, which was $43.0 million higher than December 31, 2020 balances. Cayman and the Channel Islands and UK segments saw growth in their residential mortgage portfolios, which was partially offset by the repayment of a Bermuda government agency facility during the period.

Allowance for credit losses at September 30, 2021 totaled $28.7 million, a decrease of $5.4 million from $34.1 million at December 31, 2020. The movement was due primarily to collateral sales and charge-off of loans that had previously been provisioned for, and improving macroeconomic forecasts which drive the estimate of expected credit losses.

The loan portfolio represented 33.9% of total assets at September 30, 2021 (December 31, 2020: 35.0%), while loans as a percentage of total deposits decreased to 37.5% at September 30, 2021 from 38.9% at December 31, 2020. The decrease in both ratios are attributable principally to an increase in customer deposits at September 30, 2021 due to corporate deposit increases in Cayman and the Channel Islands, and partially offset by expected corporate deposit decreases in Bermuda.

As of September 30, 2021, the Bank had gross non-accrual loans of $63.8 million, representing 1.2% of total gross loans, a decrease of $8.7 million from the $72.5 million, or 1.4% of total loans, at December 31, 2020. The decrease in non-accrual loans was driven by the payoff of residential mortgages and a commercial mortgage in Bermuda.

Other real estate owned (“OREO”) decreased by $3.4 million at September 30, 2021 due to the sale of a commercial property in Bermuda during the quarter.

Investment in Securities

The investment portfolio was $6.0 billion at September 30, 2021, up $1.1 billion from $4.9 billion in December 31, 2020. The increase is due to deployment of assets into the investment portfolio.

The investment portfolio is made up of high quality assets with 100% invested in A-or-better-rated securities. The investment book yield decreased to 1.77% during the quarter ended September 30, 2021 from 1.82% during the previous quarter. Total net unrealized gains on the available-for-sale and held-to-maturity portfolios decreased to $53.0 million, compared with total net unrealized gains of $183.2 million at December 31, 2020, as a result of increased long-term US dollar interest rates.

Deposits

Average deposits were $14.2 billion in the third quarter of 2021, an increase of $0.4 billion compared to the previous quarter.

Assets Under Administration and Assets Under Management

Total assets under administration for the trust and custody businesses were $104.4 billion and $35.6 billion, respectively, at September 30, 2021, while assets under management were $5.4 billion at September 30, 2021. This compares with $104.1 billion, $32.4 billion and $5.6 billion, respectively, at December 31, 2020.

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.
