MICHAEL O’GRADY, CHAIRMAN AND CHIEF EXECUTIVE OFFICER:

“Northern Trust began 2026 with strong financial momentum, underscoring the effectiveness of our diversified business model and continued execution of our strategic priorities. Revenue increased 14% year-over-year, supported by improved organic growth, elevated client activity across our businesses, and favorable interest rate and market conditions. Disciplined expense management and a sustained focus on operational efficiency generated more than 700 basis points of operating leverage, a 32% pre-tax margin, and a 43% rise in earnings per share. Return on equity reached 17.4% and we returned 100% of our earnings to shareholders.

While global and economic uncertainty persists, we remain focused on supporting our clients, strengthening our global franchise, and delivering lasting value for stakeholders.”

NORTHERN TRUST CORPORATION FIRST QUARTER 2026 RESULTS

RECONCILIATION TO FULLY TAXABLE EQUIVALENT

The following table presents a reconciliation of interest income, net interest income, net interest margin, total revenue, income before taxes, and pre-tax margin prepared in accordance with GAAP to such measures on an FTE non-GAAP basis. Management believes this presentation facilitates the analysis of asset yields and 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.

INTEREST RATE TRENDS (FTE(1) Basis)

PERIOD AVERAGES

Net Interest Income (FTE Adjusted), a non-GAAP financial measure, includes adjustments to a fully taxable equivalent basis for loans and securities. A reconciliation of net interest income, net interest margin, and net interest spread on a GAAP basis to net interest income, net interest margin, and net interest spread on an FTE basis, respectively, (each of which is a non-GAAP financial measure) is provided on pages 11 and 12. Net interest margin is calculated by dividing annualized net interest income by average interest-earning assets. Net interest spread is calculated as the difference between the interest rate earned (annualized interest income divided by average interest-earning assets) and the interest rate incurred (annualized interest expense divided by average interest-related funds).

RECONCILIATION TO FULLY TAXABLE EQUIVALENT

($ in Millions)

Northern Trust presents certain financial measures on a fully taxable equivalent (FTE) basis, which is a non-generally accepted accounting principle (GAAP). Management believes an FTE presentation provides a clearer indication of these financial measures for comparative purposes.

Net interest income (FTE) – Non-GAAP and net interest margin (FTE) – Non-GAAP and other FTE measures include the tax equivalent adjustments on tax-exempt income, consistent with industry practice. The adjustments are based on the federal income tax rate, where the rate is adjusted for applicable state income taxes, net of related federal tax benefit. 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. Below is a reconciliation of the financial measures presented on an FTE basis.
