7. Income Taxes

Our effective tax rate from continuing operations was 20.6% and 20.8% in the three months ended September 30, 2025 and 2024, respectively. The effective tax rate for the three months ended September 30, 2025 decreased compared to the prior year period primarily due to an increase in tax benefits on stock-based compensation, partially offset by a limitation of tax benefits on certain executive compensation. The income tax provisions reflect the U.S. federal tax rate of 21%

adjusted for taxes related to global intangible low-taxed income (“GILTI”), limitation of tax benefits on certain executive compensation, the rate of tax applied by state and local jurisdictions, the rate of tax applied to earnings outside the U.S., tax incentives, tax credits related to research and development expenditures, changes in valuation allowance, changes in uncertain tax positions, and tax benefits on stock-based compensation.

RUSM and RUSVM each have agreements with their respective domestic governments that exempt them from local income taxation. RUSM has an exemption in Barbados until 2039 and RUSVM has an exemption in St. Kitts until 2038.

In July 2025, the One Big Beautiful Bill Act (“OBBBA”) was signed into law, which introduced substantial changes to U.S. tax provisions. The most relevant provisions to Adtalem for fiscal year 2026 include allowing accelerated tax deductions for qualified property and research and development expenditures. The impacts of OBBBA were not material to the income tax provision for the three months ended September 30, 2025.
