RESULTS OF OPERATIONS

Consolidated Performance Summary. The following table presents selected consolidated financial data (dollars in millions, except per share data):

Net sales. For the three months ended June 28, 2025, net sales increased $57.5 million, or 6.0%, as compared to the three months ended June 29, 2024. For the nine months ended June 28, 2025, net sales increased $64.3 million, or 2.2%, as compared to the nine months ended June 29, 2024.

Net sales are analyzed by management by geographic segment, which reflects our reportable segments, and by market sector. Management measures operational performance and allocates resources on a geographic segment basis. Our global business development strategy is based on our targeted market sectors.

In the first quarter of fiscal 2025, we changed internal management reporting to focus on value-add sales in each region and adjusted the allocation of certain corporate costs among reportable segments. These changes have been implemented and are consistent with what was provided to the Chief Operating Decision Maker ("CODM"). Our composition of operating segments and reportable segments did not change. Net sales and operating income for our three reportable segments for the current period and comparative periods presented have been recast to conform to those changes. These changes had no effect on our consolidated net sales, operating income or net income for the current or comparative periods.

A discussion of net sales by reportable segment is presented below (in millions):

AMER. Net sales for the three months ended June 28, 2025 in the AMER segment increased $5.2 million, or 1.7%, as compared to the three months ended June 29, 2024. The increase in net sales was driven by an increase of $14.4 million due to production ramps of new products for existing customers and overall net increased customer end-market demand. The increase was partially offset by a decrease of $9.0 million due to the discontinuation of a program with an existing customer and a decrease of $8.2 million due to disengagements with customers.

During the nine months ended June 28, 2025, net sales in the AMER segment decreased $31.7 million, or 3.5%, as compared to the nine months ended June 29, 2024. The decrease in net sales was driven by overall net decreased customer end-market demand, a decrease of $24.8 million due to disengagements with customers and a decrease of $13.8 million due to the discontinuation of a program with an existing customer. The decrease was partially offset by an increase of $40.1 million due to production ramps of new products for existing customers.

During the nine months ended June 28, 2025, net sales in the Industrial sector decreased $1.9 million, or 0.2%, as compared to the nine months ended June 29, 2024. The decrease in net sales was driven by a decrease of $16.2 million due to disengagements with customers. The decrease was partially offset by overall net increased customer end-market demand.

Cost of sales. Cost of sales for the three months ended June 28, 2025 increased $48.7 million, or 5.6%, as compared to the three months ended June 29, 2024, while cost of sales for the nine months ended June 28, 2025 increased $33.3 million, or 1.3%, as compared to the nine months ended June 29, 2024. Cost of sales is comprised primarily of material and component costs, labor costs and overhead. For both the three and nine months ended June 28, 2025 and June 29, 2024, approximately 88% of the total cost of sales was variable in nature and fluctuated with sales volumes. Approximately 87% of these costs were related to material and component costs.

As compared to the three months ended June 29, 2024, the increase in cost of sales in the three months ended June 28, 2025 was primarily driven by an increase in net sales and an increase in fixed costs. As compared to the nine months ended June 29, 2024, the increase in cost of sales for the nine months ended June 28, 2025 was primarily driven by an increase in net sales, partially offset by a positive shift in customer mix and a decrease in fixed costs resulting from progress on operational efficiency initiatives.

Gross profit. Gross profit for the three months ended June 28, 2025 increased $8.9 million, or 9.4%, as compared to the three months ended June 29, 2024. Gross margin of 10.1% for the three months ended June 28, 2025 increased 30 basis points compared to the three months ended June 29, 2024. The primary drivers of the increase in gross profit and gross margin as compared to the three months ended June 29, 2024 were lower costs resulting from operational efficiencies and prior restructuring activities.

Gross profit for the nine months ended June 28, 2025 increased $31.1 million, or 11.5%, as compared to the nine months ended June 29, 2024. Gross margin of 10.1% for the nine months ended June 28, 2025 increased 80 basis points compared to the nine months ended June 29, 2024. The primary drivers of the increase in gross profit and gross margin as compared to the nine months ended June 29, 2024 were lower costs resulting from operational efficiencies and prior restructuring activities.

Operating income. Operating income for the three months ended June 28, 2025 increased $14.4 million, or 36.7%, as compared to the three months ended June 29, 2024. Operating margin of 5.3% for the three months ended June 28, 2025 increased 120 basis points compared to the three months ended June 29, 2024. The primary drivers of the increase in operating income and operating margin for the three months ended June 28, 2025 were the result of a decrease of $9.2 million in restructuring and other charges as well as the increase in gross profit and gross margin. The restructuring and other charges for the three months ended June 29, 2024 consisted of severance from the reduction in the Company's workforce as well as closure costs associated with a site in the Company's AMER region. The increase in operating income was partially offset by an increase of $3.7 million in selling and administrative expenses ("S&A"). The increase in S&A was primarily due to an increase in compensation costs.

Operating income for the nine months ended June 28, 2025 increased $35.4 million, or 31.1%, as compared to the nine months ended June 29, 2024. Operating margin of 5.0% for the nine months ended June 28, 2025 increased 110 basis points compared to the nine months ended June 29, 2024. The primary drivers of the increase in operating income and operating margin for the nine months ended June 28, 2025 were the increase in gross profit and gross margin as well as a decrease of $15.6 million in restructuring and other charges. The restructuring and other charges for the nine months ended June 28, 2025 primarily consisted of severance costs associated with a reduction in the Company's workforce in the EMEA and AMER regions. The restructuring and other charges for the nine months ended June 29, 2024 consisted of employee severance costs associated with a reduction in the Company's workforce as well as closure costs associated with sites in the Company's AMER and EMEA regions, partially offset by insurance proceeds received in an arbitration decision regarding a contractual matter that took place in the Company's EMEA region in fiscal 2023. The increase in operating income was partially offset by an increase of $11.3 million in S&A. The increase in S&A was primarily due to an increase in compensation costs.

A discussion of operating income by reportable segment for the indicated fiscal period is presented below (in millions):

AMER. Operating income increased $4.8 million for the three months ended June 28, 2025 as compared to the three months ended June 29, 2024, primarily as a result of an increase in net sales, a decrease in fixed costs resulting from progress on operational efficiency initiatives and a positive shift in customer mix.

During the nine months ended June 28, 2025, operating income in the AMER segment increased $12.6 million as compared to the nine months ended June 29, 2024, primarily as a result of a decrease in fixed costs resulting from progress on operational efficiency initiatives and a positive shift in customer mix, partially offset by a decrease in net sales.

APAC. Operating income increased $8.5 million for the three months ended June 28, 2025 as compared to the three months ended June 29, 2024, primarily as a result of an increase in net sales, partially offset by a negative shift in customer mix, an increase in fixed costs and an increase in S&A.

During the nine months ended June 28, 2025, operating income in the APAC segment increased $28.5 million as compared to the nine months ended June 29, 2024, primarily as a result of an increase in net sales, partially offset by an increase in S&A and an increase in fixed costs.

EMEA. Operating income decreased $3.4 million for the three months ended June 28, 2025 as compared to the three months ended June 29, 2024, primarily as a result of a decrease in net sales, partially offset by a decrease in fixed costs.

During the nine months ended June 28, 2025, operating income in the EMEA segment decreased $8.0 million as compared to the nine months ended June 29, 2024, primarily as a result of a decrease in net sales and an increase in S&A, partially offset by a decrease in fixed costs and a positive shift in customer mix.

Other expense. Other expense for the three months ended June 28, 2025 decreased $5.1 million as compared to the three months ended June 29, 2024. The decrease in other expense for the three months ended June 28, 2025 was primarily driven by a decrease in interest expense of $4.9 million due to lower borrowings on our credit facility and a decrease of $0.8 million in factoring fees, partially offset by an increase in foreign exchange losses of $0.6 million.

Other expense for the nine months ended June 28, 2025 decreased $18.9 million as compared to the nine months ended June 29, 2024. The decrease in other expense for the nine months ended June 28, 2025 was primarily driven by a decrease in interest expense of $14.1 million due to lower borrowings on our credit facility, a decrease of $2.9 million in factoring fees and a decrease in foreign exchange losses of $1.4 million.

Income taxes. Income tax expense for the three and nine months ended June 28, 2025 was $4.7 million and $16.9 million, respectively, compared to $5.2 million and $13.5 million for the three and nine months ended June 29, 2024. The decrease for the three months ended June 28, 2025 compared to the three months ended June 29, 2024 is primarily due to an increase in discrete tax benefits of $2.9 million. The increase for the nine months ended June 28, 2025 compared to the nine months ended June 29, 2024 is primarily due to an increase in pre-tax book income, partially offset by an increase in discrete tax benefits of $4.4 million.

Our annual effective tax rate varies from the U.S. statutory rate of 21.0% primarily due to the geographic distribution of worldwide earnings as well as a tax holiday granted to a subsidiary located in the APAC segment where we derive a significant portion of our earnings. Our effective tax rate may also be impacted by disputes with taxing authorities, tax planning activities, adjustments to uncertain tax positions and changes in valuation allowances.

The annual effective tax rate for fiscal 2025 is expected to be approximately 10.0% to 12.0% assuming no changes to tax laws.

On July 4, 2025, the “One Big Beautiful Bill Act” (the “Act”) was enacted into law. The Act includes changes to U.S. tax law that has multiple effective dates through fiscal 2027. We are in the process of evaluating the impact of the Act to our Consolidated Financial Statements.

Net income. Net income for the three months ended June 28, 2025 increased $20.0 million, or 79.7%, from the three months ended June 29, 2024 to $45.1 million. Net income increased primarily as a result of the increase in operating income and the decrease in other expense and tax expense as previously discussed.

Net income for the nine months ended June 28, 2025 increased $50.9 million, or 72.1%, from the nine months ended June 29, 2024 to $121.5 million. Net income increased primarily as a result of the increase in operating income and the decrease in other expense, partially offset by the increase in tax expense as previously discussed.

Diluted earnings per share. Diluted earnings per share increased to $1.64 for the three months ended June 28, 2025 from $0.91 for the three months ended June 29, 2024, primarily as a result of increased net income due to the factors discussed above.

Diluted earnings per share increased to $4.39 for the nine months ended June 28, 2025 from $2.53 for the nine months ended June 29, 2024, primarily as a result of increased net income due to the factors discussed above.

Return on Invested Capital ("ROIC") and economic return. We use a financial model that is aligned with our business strategy and includes an ROIC goal of 15%, which would exceed our weighted average cost of capital ("WACC") by more than 500 basis points and represent positive economic return. Economic return is the amount our ROIC exceeds our WACC.

Non-GAAP financial measures, including ROIC and economic return, are used for internal management goals and decision making because such measures provide management and investors additional insight into financial performance. In particular, we provide ROIC and economic return because we believe they offer insight into the metrics that are driving management decisions. We view ROIC and economic return as important measures in evaluating the efficiency and effectiveness of our long-term capital investments. We also use ROIC as a performance criteria in determining certain elements of compensation as well as economic return performance.

We define ROIC as tax-effected operating income before restructuring and other charges divided by average invested capital over a rolling four-quarter period for the third fiscal quarter. Invested capital is defined as equity plus debt and operating lease liabilities, less cash and cash equivalents. Other companies may not define or calculate ROIC in the same way. ROIC and other non-GAAP financial measures should be considered in addition to, not as a substitute for, measures of our financial performance prepared in accordance with U.S. generally accepted accounting principles ("U.S. GAAP").

We review our internal calculation of WACC annually. Our WACC is 8.9% for fiscal 2025 and 8.2% for fiscal 2024. By exercising discipline to generate ROIC in excess of our WACC, our goal is to create value for our shareholders. For the nine months ended June 28, 2025, ROIC of 14.1% reflects an economic return of 5.2%, based on our WACC of 8.9%, and for the nine months ended June 29, 2024, ROIC of 10.4% reflects an economic return of 2.2%, based on our WACC of 8.2%.

For a reconciliation of ROIC, economic return and adjusted operating income (tax-effected) to our financial statements that were prepared using U.S. GAAP, see Exhibit 99.1 to this Quarterly Report on Form 10-Q, which exhibit is incorporated herein by reference.

Refer to the table below, which includes the calculation of ROIC and economic return for the indicated fiscal period (dollars in millions):
