[1] State taxes in California, Illinois, Minnesota, New York, Maryland, and Georgia make up the majority (greater than 50%) of this category. State taxes include the one-time release of a $114.0 million valuation allowance from state deferred tax assets, other than California R&D.
[2] During the fiscal year ended July 31, 2026, we recorded a $1,094.2 million tax benefit related to the release of our valuation allowance on U.S. federal deferred tax assets, partially offset by $1.2 million of tax expense related to the increase in the valuation allowance for capital losses generated during fiscal 2026.
