On July 4, 2025, the U.S. government enacted tax legislation known as the One Big Beautiful Bill Act (the “OBBBA”). The OBBBA makes broad and complex changes to the U.S. tax code. The OBBBA federal provisions include, but are not limited to (1) bonus depreciation that will allow for full expensing of property acquired and placed in service after January 19, 2025, (2) permanent add back of interest, depreciation, amortization and depletion in computing the 30% limitation under Section 163(j) for taxable years beginning after December 31, 2024, and (3) permanent expensing of domestic research and development expenditures for taxable years beginning after December 31, 2024. The OBBBA also modifies several international provisions for taxable years beginning after December 31, 2025, including, but not limited to (1) reduced deduction of 40% for the global intangible low-taxed income regime, now referred to as Net CFC Tested Income, (2) reduced deduction of 33.34% for the foreign-derived intangible income regime, now called Foreign-Derived Deduction Eligible Income, and (3) permanent base erosion and anti-abuse tax rate of 10.5%.
ASC Topic 740, Income Taxes requires companies to recognize the effects of tax law changes in the period of enactment, which for Mallinckrodt is the third quarter of 2025. The Company is currently analyzing the OBBBA provisions and the impact on its consolidated financial statements.
The Company recognized an income tax expense of $10.7 million and $14.6 million on income from continuing operations before income taxes of $13.0 million and loss from continuing operations before income taxes of $11.0 million for the three and six months ended June 27, 2025, respectively. This resulted in an effective tax rate of 82.3% and negative 132.7%, respectively. The effective tax rate differs from the Irish statutory tax rate of 12.5% primarily due to the mix of pretax earnings in various jurisdictions, remaining effects of adoption of fresh-start accounting as a result of the Company’s emergence from the 2023 Chapter 11 proceedings and Irish examinership proceedings (together, the “2023 Bankruptcy Proceedings”), and non-deductible costs associated with employee compensation and combination, integration, and other related expenses for both periods.
The Company recognized an income tax expense of $13.9 million and $13.2 million on losses from continuing operations before income taxes of $29.5 million and $95.8 million for the three and six months ended June 28, 2024, respectively. This resulted in an effective tax rate of negative 47.1% and negative 13.8%, respectively. The effective tax rate differs from the Irish statutory tax rate of 12.5% primarily due to the impact of valuation allowances recorded for current year interest limitations, the mix of pretax earnings in various jurisdictions, and remaining effects of adoption of fresh-start accounting as a result of emergence from the 2023 Bankruptcy Proceedings for both periods.
During the six months ended June 27, 2025 and June 28, 2024, net cash payments for income taxes were $5.2 million and $2.7 million, respectively, related to operational activity.
On December 20, 2021, the Organization for Economic Co-operation and Development released the Global Anti-Base Erosion Model Rules (“Pillar Two”) providing a legislative framework for the Income Inclusion Rule and the Under-Taxed Payment Rule (“UTPR”). Pillar Two is designed to ensure that large multinational enterprise groups pay a minimum level of tax on the income arising in each of the jurisdictions where they operate, principally creating a 15% minimum global effective tax rate. On December 15, 2022, the E.U. member states unanimously adopted a directive implementing the Pillar Two global minimum tax rules. A number of jurisdictions have transposed the directive into national legislation with the rules applicable for fiscal years beginning on or after December 31, 2023, with the exception of the UTPR which is applicable for fiscal years beginning on or after December 31, 2024. For the fiscal year beginning December 28, 2024, the Company was in scope of the enacted or substantively enacted legislation and an assessment of the potential exposure to Pillar Two income taxes was performed using forecasted financial information for the fiscal year ended December 26, 2025. Based on the assessment, certain transitional safe harbor relief applied for most jurisdictions, and where the transitional safe harbor relief did not apply, the impact to income tax expense was not material.
The Company's unrecognized tax benefits, excluding interest, totaled $32.2 million and $31.1 million as of June 27, 2025 and December 27, 2024, respectively. It is reasonably possible that within the next twelve months the unrecognized tax benefits could decrease by up to $5.0 million and the amount of related interest and penalties could decrease by up to $3.8 million as a result of the expiration of a statute of limitations.
