SEGMENT AND CORPORATE RESULTS

The increase in revenues for the three months ended July 4, 2025, as compared to the three months ended June 28, 2024, was primarily attributable to program wins and $12 million of revenues recognized from the acquisition of Savanna Industries, Inc. ("Kudu Dynamics"), partially offset by the completion of certain programs.

The increase in revenues for the six months ended July 4, 2025, as compared to the six months ended June 28, 2024, was primarily attributable to program wins, a net increase in volumes on certain programs and $12 million of revenues recognized from the acquisition of Kudu Dynamics, partially offset by the completion of certain programs.

The increase in revenues and operating income for the three months ended July 4, 2025, as compared to the three months ended June 28, 2024, was primarily attributable to increased volumes within the managed health services business as well as net write-ups on certain programs.

The increase in revenues for the three months ended July 4, 2025, as compared to the three months ended June 28, 2024, was primarily attributable to program wins, prior year write-downs on certain programs within our UK operations and a $8 million favorable impact from exchange rate movements. The increase was partially offset by lower material volumes and the completion of certain programs.

The increase in operating income for the six months ended July 4, 2025, as compared to the six months ended June 28, 2024, was primarily attributable to program wins and prior year write-downs on certain programs within our UK operations, partially the completion of certain programs and increased indirect costs.

The increase in revenues for the three and six months ended July 4, 2025, as compared to the three and six months ended June 28, 2024, was primarily attributable to program wins and a net increase in volumes, partially offset by the completion of certain programs and program write-ups in the prior year that did not reoccur in the current year.

The increase in operating income for the three and six months ended July 4, 2025, as compared to the three and six months ended June 28, 2024, was primarily attributable to program wins, partially offset by program write-ups in the prior year that did not reoccur in the current year.

The decrease in operating loss for the three and six months ended July 4, 2025, as compared to the three and six months ended June 28, 2024, was primarily attributable to the receipt of a $25 million insurance reimbursement for legal costs primarily incurred prior to fiscal year 2025, and decreased general and administrative expenses.

NON-OPERATING EXPENSE, NET

Non-operating expense, net for the three months ended July 4, 2025, was $53 million as compared to $49 million for the three months ended June 28, 2024. The increase was primarily driven by increased interest expense as a result of the two $500 million senior notes issued in February 2025.

Non-operating expense, net for the six months ended July 4, 2025, was $105 million as compared to $96 million for the six months ended June 28, 2024. The increase was primarily driven by increased interest expense as a result of the two $500 million senior notes issued in February 2025 and unfavorable exchange rate movements.

PROVISION FOR INCOME TAXES

On July 4, 2025, tax legislation was enacted in H.R.1 Reconciliation Act, commonly referred to as the One Big Beautiful Bill Act (the “OBBBA”) implementing several corporate tax law changes, including but not limited to, (1) restoring the immediate expensing of U.S. research and development costs; (2) allowing certain taxpayers an election to deduct the unamortized balance of U.S. research and development costs capitalized in prior years; and (3) reinstating one hundred percent bonus depreciation for eligible property. The enactment of the OBBBA resulted in a decrease of $150 million to income taxes payable and a decrease of $130 million to deferred tax assets as of July 4, 2025. Based upon our interpretation of the law as currently enacted, we estimate that the fiscal 2025 impact will result in a decrease of approximately $280 million to income taxes payable and a decrease of $245 million to net deferred taxes.

For the three months ended July 4, 2025, our effective tax rate was 24.1% compared to 23.9% for the three months ended June 28, 2024. The increase to the effective tax rate was primarily due to impacts from the OBBBA, partially offset by a decrease in unrecognized tax benefits.

For the six months ended July 4, 2025, our effective tax rate was 23.9% compared to 23.6% for the six months ended June 28, 2024. The increase to the effective tax rate was primarily due to impacts from the OBBBA and a decrease in excess tax benefits related to employee stock-based payment transactions, partially offset by a decrease in unrecognized tax benefits.

In December 2021, the Organization for Economic Cooperation and Development enacted model rules for a new 15% global minimum tax framework (“Pillar Two”). Many governments around the world have enacted or are in the process of enacting Pillar Two legislation. The Pillar Two legislation became effective for certain jurisdictions beginning in fiscal 2024. We will continue to evaluate the impact of the rules as additional legislation gets enacted; however, there has been no material impact from jurisdictions where Pillar Two rules are currently in effect.
