NORTHERN TRUST CORPORATION REPORTS SECOND QUARTER
NET INCOME OF $368.1 MILLION, EARNINGS PER DILUTED COMMON SHARE OF $1.72

Trust, Investment and Other Servicing Fees up 12% YoY	Common Equity Tier 1 Capital 12.0%	Return on Average Common Equity 13.7%

CHICAGO, JULY 21, 2021 - Northern Trust Corporation today reported second quarter net income per diluted common share of $1.72, compared to $1.70 in the first quarter of 2021 and $1.46 in the second quarter of 2020. Net income was $368.1 million, compared to $375.1 million in the prior quarter and $313.3 million in the prior-year quarter. The current quarter included a $17.6 million pre-tax pension settlement charge.

MICHAEL O'GRADY, CHAIRMAN AND CHIEF EXECUTIVE OFFICER:

'Northern Trust's performance in the second quarter reflected continued strong momentum across all of our businesses. Revenue and net income grew by 5% and 18%, respectively, compared to the prior year, and we generated a return on average common equity of 13.7%. Revenue growth was driven by new business and favorable markets against the adverse impact of low interest rates. Trust, investment and other servicing fees grew 12% and were partially offset by a 9% decline in net interest income. Expense increased 8%, driven primarily by new business, investments in technology, unfavorable currency translation and a pension settlement charge. Similar to the prior quarter, we also benefited from an improved outlook in projected economic conditions driving a release of reserves for credit losses. We continued to focus on serving our clients, executing on our long-term priorities, driving operating efficiency and investing wisely for future profitable growth.'

Q2 2021

The release of credit reserves in the current quarter was primarily due to a decrease in the reserve evaluated on a collective basis, which relates to pooled financial assets sharing similar risk characteristics. The decrease in the collective basis reserve was driven by continued improvements in overall projected economic conditions, as well as improved industry-specific conditions, partially offset by credit deterioration associated with a limited number of commercial real estate loans and overall portfolio growth.

Q1 2021

The release of credit reserves in the prior quarter was primarily due to a decrease in the reserve evaluated on a collective basis, driven by continued improvement in projected economic conditions and portfolio credit quality relative to Q4 2020, with decreases primarily in the commercial and institutional, commercial real estate, and private client portfolios.

Q2 2020

The provision in the prior-year quarter was primarily due to an increase in the reserve evaluated on a collective basis driven by downgrades in the portfolio and more severe projected economic conditions at the time, both resulting from the ongoing COVID-19 pandemic and related market and economic impacts, with the largest increases in the commercial and institutional and commercial real estate portfolios.

RECONCILIATION TO FULLY TAXABLE EQUIVALENT

The following table presents a reconciliation of interest income, net interest income, net interest margin, and total revenue prepared in accordance with generally accepted accounting principles to such measures on an FTE basis, which are non-generally accepted accounting financial measures. Net interest margin is calculated by dividing annualized net interest income by average interest-earning assets. Management believes this presentation provides a clearer indication of these financial measures for comparative purposes. When adjusted to an FTE basis, yields on taxable, nontaxable and partially taxable assets are comparable; however, the adjustment to an FTE basis has no impact on net income.
