As of September 30, 2025, the Company had $168.2 million of potential tax benefits from federal and state net operating loss and other tax attribute carryforwards and $491.6 million of potential tax benefits from foreign loss carryforwards, both of which have varying expiration dates. The Company had $1.5 million of federal tax credit carryforwards, $1.0 million of state tax credit carryforwards, and $3.1 million of foreign alternative minimum tax credit carryforwards.
The Company assesses the available positive and negative evidence to determine whether deferred tax assets are more likely than not to be realized. As a result of this assessment, valuation allowances have been recorded on certain deferred tax assets. For fiscal 2025, the Company increased the valuation allowance on deferred tax assets by $59.5 million primarily due to the change in the valuation allowance against foreign net operating loss carryforwards. For fiscal 2024, the Company decreased the valuation allowance on deferred tax assets by $35.0 million primarily due to the increase in the valuation allowance against tax deductible goodwill.
In fiscal 2025, 2024, and 2023, tax benefits of $16.0 million, $15.0 million, and $24.6 million, respectively, related to the exercise of employee stock options and lapses of restricted stock units were recorded in Income Tax Expense in the Company’s Consolidated Statements of Operations. The tax benefits recognized in fiscal 2025, 2024, and 2023 are not necessarily indicative of amounts that may arise in future periods.
Income tax payments, net of refunds, were $571.2 million, $603.9 million, and $463.1 million in fiscal 2025, 2024, and 2023, respectively.
Cumulative undistributed earnings of international subsidiaries were $4.3 billion as of September 30, 2025, $2.3 billion of which is considered permanently reinvested. It is not practicable to estimate the taxes that would be due if such earnings were to be repatriated in the future.
The Company and its subsidiaries file income tax returns in the U.S. federal jurisdiction and various states and foreign jurisdictions. The Company is currently undergoing certain state and local income tax audits for various years. With few exceptions, the Company is no longer subject to U.S. federal, state and local, or foreign income tax examinations by tax authorities for years before 2020. The Company believes it has adequate tax reserves to cover potential federal, state or foreign tax exposures.
Unrecognized Tax Benefits
As of September 30, 2025 and 2024, the Company had unrecognized tax benefits, defined as the aggregate tax effect of differences between tax return positions and the benefits recognized in the Company’s financial statements, of $640.5 million and $545.0 million, respectively ($583.8 million and $498.0 million, net of federal tax benefit, respectively). If recognized in fiscal 2025 and 2024, $574.0 million and $488.1 million, respectively, of these benefits would have reduced income tax expense and the effective tax rate. As of September 30, 2025 and 2024, included in the unrecognized tax benefits are $72.3 million and $43.9 million of interest and penalties, respectively, which the Company records in Income Tax Expense in the Company’s Consolidated Statements of Operations.
A reconciliation of the beginning and ending amount of unrecognized tax benefits, excluding interest and penalties, for the periods indicated is as follows:
| | | | | | | | | | | | | | | | | | | | |
| | Fiscal Year Ended September 30, |
| (in thousands) | | 2025 | | 2024 | | 2023 |

| Reductions of tax positions of the prior years | | — | | | (37,520) | | | (31,110) | |
| Settlements and expiration of statutes of limitations | | (12,406) | | | (2,410) | | | (3,457) | |

| Unrecognized tax benefits at end of period | | $ | 568,159 | | | $ | 501,064 | | | $ | 525,933 | |
During the next 12 months, the Company does not anticipate any material change in unrecognized tax benefits due to tax audit resolutions and the expiration of statutes of limitations.
A significant portion of the Company’s unrecognized tax benefits as of September 30, 2025 relates to the legal accrual for litigation related to the Distributor Settlement Agreement, as well as other opioid-related litigation, as disclosed in Note 12. The Company has applied significant judgment in estimating the amount of the opioid settlements that will be deductible for U.S. federal and state purposes. In estimating the amount that would be deductible, the Company considered prior U.S. tax case law, the amount and character of the damages sought in litigation, and other relevant factors.
