FORWARD-LOOKING STATEMENTS

This Quarterly Report on Form 10-Q (the “Quarterly Report”) contains forward-looking statements within the meaning of the Private Securities Litigation Reform Act of 1995. We intend such forward-looking statements to be covered by the safe harbor provisions for forward-looking statements contained in Section 27A of the Securities Act of 1933, as amended, and Section 21E of the Securities Exchange Act of 1934, as amended (the “Exchange Act”). All statements other than statements of historical facts contained in this Quarterly Report, including statements regarding our future results of operations and financial position, business strategy, prospective products and the plans and objectives of management for future operations, may be forward-looking statements. These statements involve known and unknown risks, uncertainties and other important factors that may cause our actual results, performance or achievements to be materially different from any future results, performance or achievements expressed or implied by the forward-looking statements.

Statements regarding our future results of operations and financial position, business strategy and plans and objectives of management for future operations, including, among others, statements regarding the liquidity, growth and profitability strategies and factors and trends affecting our business are forward-looking statements. Without limiting the foregoing, in some cases, you can identify forward-looking statements by terms such as “aim,” “may,” “will,” “should,” “expect,” “exploring,” “plan,” “anticipate,” “could,” “intend,” “target,” “project,” “would,” “contemplate,” “believe,” “estimate,” “predict,” “potential,” “seek,” or “continue” or the negative of these terms or other similar expressions, although not all forward-looking statements contain these words. No forward-looking statement is a guarantee of future results, performance, or achievements, and one should avoid placing undue reliance on such statements.

Forward-looking statements are based on our management’s beliefs and assumptions and on information currently available to us. Such beliefs and assumptions may or may not prove to be correct. Additionally, such forward-looking statements are subject to a number of known and unknown risks, uncertainties and assumptions, and actual results may differ materially from those expressed or implied in the forward-looking statements due to various factors, including, but not limited to, those identified in Part I, Item 2. “Management’s Discussion and Analysis of Financial Condition and Results of Operations” and Part II, Item 1A. “Risk Factors” in this Quarterly Report and Part I, Item 1A. “Risk Factors” in our Annual Report on Form 10-K for the year ended March 27, 2026, filed with the Securities and Exchange Commission (“SEC”) on May 21, 2026 (the “2026 Annual Report”), as any such factors may be updated from time to time in our Quarterly Reports on Form 10-Q, and our other filings with the SEC.

You should read this Quarterly Report and the documents that we reference completely and with the understanding that our actual future results may be materially different from what we expect. We qualify all of our forward-looking statements by these cautionary statements. All forward-looking statements speak only as of the date of this Quarterly Report, and except as required by applicable law, we do not plan to publicly update or revise any forward-looking statements, whether as a result of any new information, future events, or otherwise.

Unless the context otherwise requires, references to “we,” “us,” “our,” the “Company” and “Allegro” refer to the operations of Allegro MicroSystems, Inc. and its consolidated subsidiaries.

Notes to Unaudited Condensed Consolidated Financial Statements

(Amounts in thousands, except share and per share amounts)

1. Nature of the Business and Basis of Presentation

Allegro MicroSystems, Inc., together with its consolidated subsidiaries (the “Company”), is a global leader in the design, development, and marketing of sensor integrated circuits (“ICs”) and application-specific power ICs that enable the sensing, motion control, power management and isolation functions of complex electromechanical or power conversion systems. The Company primarily serves automotive and industrial markets, where its solutions enable customers to sense, move, manage and isolate power with efficiency, precision, and reliability. The Company is incorporated under the laws of Delaware. The Company is headquartered in Manchester, New Hampshire and has a global footprint across multiple continents.

The accompanying unaudited condensed consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States (“GAAP”). Certain information and footnote disclosures normally included in the Company’s annual audited consolidated financial statements and accompanying notes have been condensed in, or omitted from, these interim financial statements. These unaudited condensed consolidated financial statements include the Company’s accounts and those of its subsidiaries. All intercompany transactions and balances have been eliminated in consolidation. These unaudited condensed consolidated financial statements should be read in conjunction with the consolidated financial statements and notes thereto included in the 2026 Annual Report. The March 27, 2026 Condensed Consolidated Balance Sheet included herein is derived from the Company’s audited consolidated financial statements. In the opinion of the Company’s management, the financial statements for the interim periods presented reflect all adjustments necessary for a fair statement of the Company’s financial position, results of operations and cash flows. The results reported in these unaudited condensed consolidated financial statements are not necessarily indicative of results that may be expected for the entire year.

Financial Periods

The Company’s second quarter three-month period is a 13-week period. The Company’s second quarter of fiscal year 2027 ended September 25, 2026, and the Company’s second quarter of fiscal year 2026 ended September 26, 2025.

2. Summary of Significant Accounting Policies

Use of Estimates

The preparation of consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets, liabilities, and disclosures of contingencies at the date of the consolidated financial statements and the reported amounts of net sales and expenses during the reporting period. On an ongoing basis, management evaluates its estimates, assumptions and judgments, including those related to the valuation of acquired intangible assets, impairment assessment and valuation of goodwill, intangible assets and tangible long-lived assets, the net realizable value of inventory, income taxes, stock-based compensation, and sales allowances. Actual results could differ from those estimates, and such differences may be material to the consolidated financial statements.

Reclassifications

Certain reclassifications have been made to prior-period amounts to conform to current-period reporting classifications.

Concentrations of Credit Risk

As of both September 25, 2026 and March 27, 2026, no distributor or customer accounted for 10.0% or more of the Company’s outstanding trade accounts receivable.

Segment Information

The Company operates as one reportable segment, which involves the design, development, production and distribution of a portfolio of ICs in various markets worldwide. The Company has a single, company-wide management team that administers all properties as a whole rather than as discrete operating segments. The Chief Operating Decision Maker (“CODM”), who is the Company’s Chief Executive Officer, measures financial performance as a single enterprise and not on a legal entity or end market basis. The CODM uses consolidated net income or loss, as reported in the Condensed Consolidated Statement of Operations, as the profitability measure in making decisions. The measure of segment assets is reported on the Condensed Consolidated Balance Sheet as total assets. Throughout the year, the CODM allocates capital resources on a project-by-project basis across the Company’s entire asset base to maximize profitability without regard to a legal entity or end market basis. The Company operates in a number of countries throughout the world in a variety of product lines through its business unit structure.

Recent Accounting Pronouncements

In July 2025, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) No. 2025-05, Financial Instruments—Credit Losses (Topic 326): Measurement of Credit Losses for Accounts Receivable and Contract Assets (“ASU 2025-05”). ASU 2025-05 provides a practical expedient that can be elected to be applied to accounts receivable and contract assets, which would allow entities to assume that current conditions as of the balance sheet date do not change for the remaining life of the assets when estimating expected credit losses for such assets. The Company adopted ASU 2025-05 on a prospective basis effective March 28, 2026, and the adoption did not have a material impact on the Company’s consolidated financial statements. In connection with this adoption, the Company elected to apply the practical expedient permitted by the standard, which assumes that current conditions as of the balance sheet date do not change for the remaining life of its applicable financial assets.

In November 2024, the FASB issued ASU No. 2024-03, Income Statement—Reporting Comprehensive Income—Expense Disaggregation Disclosures (Subtopic 220-40): Disaggregation of Income Statement Expenses (“ASU 2024-03”). ASU 2024-03 requires additional disclosures of the nature of expenses included in the Company’s income statement. The new standard requires disclosures about specific types of expenses included in the expense captions presented on the face of the income statement as well as disclosures about selling expenses. ASU 2024-03 will be applied prospectively with the option for retrospective application. The FASB subsequently issued ASU No. 2025-01, Income Statement—Reporting Comprehensive Income—Expense Disaggregation Disclosures (Subtopic 220-40) to clarify that all public business entities are required to adopt the guidance as stipulated in ASU 2024-03 in annual reporting periods beginning after December 15, 2026 and interim reporting periods within annual reporting periods beginning after December 15, 2027. Early adoption is permitted. The Company is currently evaluating the impact of adopting this guidance.

All other recent accounting pronouncements were determined to not have a material impact on the Company’s financial position, results of operations, cash flows, or related disclosures.

On August 6, 2024, upon entry into Amendment No. 2 (the “Second Amendment”) to the 2023 Revolving Credit Agreement, the total capacity of the revolving credit facility was increased to $256,000, and the Second Amendment also provided for a new $400,000 tranche of term loans maturing in 2030 (the “2024 Term Loans”), which were paid in full in connection with entry into the Third Amendment (as defined below). The revolving credit facility is available until, and loans made thereunder will mature on,
June 21, 2028. Under the terms of the 2023 Revolving Credit Agreement, interest is calculated at a rate equal to (i) Term SOFR (as defined in the 2023 Revolving Credit Agreement) in effect, plus the applicable spread (ranging from 1.50% to 1.75%) or (ii) the highest of (x) the Federal funds rate, as published by the Federal Reserve Bank of New York, plus 0.50%, (y) the prime lending rate, or (z) the one-month Term SOFR plus 1.00% in effect, plus the applicable spread (ranging from 0.50% to 0.75%). The applicable spreads are based on the Company’s Total Net Leverage Ratio (as defined in the 2023 Revolving Credit Agreement) at the time of the applicable borrowing. Issuance costs related to the revolving credit facility were not significant. As of September 25, 2026, there were no outstanding borrowings under the revolving credit facility.

The Company will also pay a quarterly commitment fee of 0.20% to 0.25% on the daily amount by which the commitments under the revolving credit facility exceed the outstanding loans and letters of credit under the revolving credit facility. The 2023 Revolving Credit Agreement contains certain covenants applicable to the Company and its subsidiaries, including limitations on additional indebtedness, liens, various fundamental changes, dividends and distributions, investments (including acquisitions), transactions with affiliates, asset sales, prepayment of junior financing, changes in business and other limitations customary in senior secured credit facilities. In addition, the Company is required to maintain a Total Net Leverage Ratio of no more than 4.00 to 1.00 at the end of each fiscal quarter, which may, subject to certain limitations, be increased to 4.50 to 1.00 for four fiscal quarters subsequent to the Company completing an acquisition for consideration in excess of $500,000.

The 2023 Revolving Credit Agreement provides for customary events of default. Upon an event of default, the administrative agent with the consent of, or at the request of, the holders of more than 50% in principal amount of the loans and commitments, may terminate the commitments and accelerate the maturity of the loans and enforce certain other remedies.

The Company was in compliance with the revolving credit facility covenants as of September 25, 2026.

Refinancing and Repricing of Term Loans

On February 6, 2025, the Company entered into Amendment No. 3 (the “Third Amendment”) to the 2023 Revolving Credit Agreement. The Third Amendment provided for a new $375,000 tranche of term loans maturing in 2030 (the “2025 Refinanced Loans”), the proceeds of which were used, in relevant part, to (i) refinance all outstanding borrowings under the 2024 Term Loans, (ii) pay fees and expenses in connection with the foregoing, and (iii) for general corporate purposes. The 2025 Refinanced Loans amortized at a rate of 0.00% per annum. The 2025 Refinanced Loans bore interest, at the Company’s option, at a rate equal to (i) Term SOFR in effect from time to time plus 2.00% or (ii) the highest of (x) the Federal funds rate, as published by the Federal Reserve Bank of New York, plus 0.50%, (y) the prime lending rate or (z) the one-month Term SOFR plus 1.00% in effect from time to time plus 1.00%. The 2025 Refinanced Loans were scheduled to mature on October 31, 2030.

On January 21, 2026, the Company entered into Amendment No. 4 (the “Fourth Amendment”) to the 2023 Revolving Credit Agreement. The Fourth Amendment provided for a new $285,000 tranche of term loans maturing in October 2030 (the “2026 Refinanced Loans”), the proceeds of which were used, in relevant part, to refinance all outstanding borrowing under the 2025 Refinanced Loans. The 2026 Refinanced Loans amortize at a rate of 0.00% per annum. The 2026 Refinanced Loans bear interest, at the Company’s option, at a rate equal to (i) Term SOFR in effect from time to time plus 1.75% or (ii) the highest of (x) the Federal funds rate, as published by the Federal Reserve Bank of New York, plus 0.50%, (y) the prime lending rate or (z) the one-month Term SOFR plus 1.00% in effect from time to time plus 0.75%. The 2026 Refinanced Loans will mature on October 31, 2030.

A payment of $25,000 was applied to the outstanding balance of the 2026 Refinanced Loans on September 30, 2026.

10. Commitments and Contingencies

Legal proceedings

The Company is subject to various legal proceedings, claims, and regulatory examinations or investigations arising in the normal course of business, the outcomes of which are subject to significant uncertainty, and the Company’s ultimate liability, if any, is difficult to predict. The Company records an accrual for legal contingencies when it is determined that it is probable that a liability has been incurred and the amount of the loss can be reasonably estimated. In making such determinations, the Company evaluates, among other things, the degree of probability of an unfavorable outcome and when it is probable that a liability has been incurred, the ability to make a reasonable estimate of the loss. If the occurrence of liability is probable and estimable, the Company will disclose the nature of the contingency and the likely amount of such loss or range of loss. The Company is not aware of any pending or threatened legal proceeding against the Company that it believes could have a material adverse effect on the Company’s business, operating results, cash flows or financial position.

13. Income Taxes

The Company recorded the following income tax provision (benefit) in its condensed consolidated statements of operations:


	Three-Month Period Ended						Six-Month Period Ended
	September 25, 2026			September 26, 2025			September 25, 2026			September 26, 2025
Income tax provision (benefit)	$	4,510		$	(9,298	)	$	6,016		$	(6,129	)
Effective tax rate		16.2	%		342.5	%		13.3	%		48.2	%

The Company’s income tax provision (benefit) is comprised of year-to-date taxes based on an estimate of the annual effective tax rate plus the tax impact of discrete items.

The Company is subject to tax in the U.S. and various foreign jurisdictions. The Company’s effective income tax rate fluctuates primarily because of the change in the mix of its U.S. and foreign income, the impact of discrete transactions and law changes, the deduction for foreign-derived deduction-eligible income (formerly foreign-derived intangible income) (“FDDEI”), including the permanent impacts of capitalized domestic and foreign research expenses, and research credits, offset by non-deductible, stock-based compensation and other charges.

In 2017, the Tax Cuts and Jobs Act (“TCJA”) introduced significant U.S. corporate tax reform to the U.S. Internal Revenue Code (the “Code”), including a requirement to capitalize domestic and foreign research and development expenditures incurred in fiscal years 2023 through 2025. The capitalized amounts were required to be amortized over five and 15 years, respectively. On
July 4, 2025, the One Big Beautiful Bill Act (“OBBB”) was enacted into law, and in general, it extended and modified many of the TCJA provisions of the Code. Specifically, the OBBB provided options to taxpayers such as (i) restoring the ability to immediately expense domestic research and development expenditures (“R&D”), (ii) providing a one-time election to accelerate the deduction of previously capitalized domestic R&D over a two-tax year period (“Accelerated R&D Amortization Election”), (iii) reinstating Section 59(e) of the Code to allow domestic R&D to be capitalized and amortized over 10 years, and (iv) updating Section 280C of the Code, which reduces the benefit of the Section 41 R&D Credit. The OBBB changes, especially the Accelerated R&D Amortization Election, result in a current year reduction of the U.S. cash taxes, FDDEI deduction, and R&D credit benefits.

The change in the effective tax rates for the three- and six-month periods primarily resulted from the significant increase in GAAP income before taxes, partially offset by an FDDEI deduction, stock-based compensation windfalls, and R&D credit benefits.

Overview

We are a global leader in the design, development, and marketing of sensor integrated circuits (“ICs”) and application-specific power ICs that enable the sensing, motion control, power management and isolation functions of complex electromechanical or power conversion systems. We primarily serve automotive and industrial markets, including advanced industrial markets such as Artificial Intelligence (“AI”) data centers, robotics, and energy infrastructure, where our solutions enable customers to sense, move, manage and isolate power with efficiency, precision, and reliability.

Our sensor ICs provide critical feedback for motion, position, speed, and electrical current sensing, while our power ICs control motors, manage power conversion and regulation, and provide high-voltage isolation across a wide range of applications. By embedding system-level intelligence directly into our products, we reduce the number of components required in a customer’s design while improving performance, energy efficiency, safety, and reliability. We believe our deep application knowledge, differentiated technology, and strong customer relationships enable us to deliver solutions that are more integrated, intelligent and efficient than typical ICs.

We are headquartered in Manchester, New Hampshire and have a global footprint across multiple continents. Our portfolio includes more than 1,500 products, and we ship over 2 billion units annually to more than 15,000 customers worldwide. During the three- and six-month periods ended September 25, 2026, we generated $276.9 million and $536.1 million in total net sales, respectively, with $23.3 million and $39.2 million in net income, respectively. During the three- and six-month periods ended September 26, 2025, we generated $214.3 million and $417.7 million in total net sales, respectively, with $6.6 million in net income and $6.6 million in net loss, respectively.

Other Key Factors and Trends Affecting Our Operating Results

Our financial condition and results of operations have been, and will continue to be, affected by numerous other factors and trends, including the following:

Inflation

While global inflation rates have remained persistent, the markets in which we operate have remained elevated and may continue to rise as a result of cost increases attributable to a rise in global energy and commodity prices and global tariff policies. Inflation in recent quarters has led us to experience higher costs, including higher labor costs, wafer and other costs for materials from suppliers, and transportation and energy costs. Our suppliers have raised their prices in recent years and may continue to raise prices, and in the competitive markets in which we operate, we may not be able to make corresponding price increases to preserve our gross margins and profitability. If inflation rates continue to rise or remain elevated for a sustained period of time, they could have a material adverse effect on our business, financial condition, results of operations and liquidity. While we have attempted to offset increases in these costs through various productivity and cost reduction initiatives, as well as adjusting our selling prices and releasing new products with improved gross margins, our ability to increase our average selling prices (“ASPs”) depends on market conditions and competitive dynamics. Given the timing of our actions compared to the timing of these inflationary pressures, there may be periods during which we are unable to fully recover the increases in our costs.

Design Wins with New and Existing Customers

Our end customers continually develop new products in existing and new application areas, and we work closely with most of our significant original equipment manufacturer (“OEM”) customers in our target markets to understand their product roadmaps and strategies. For new products, the time from design initiation and manufacturing until we generate sales can be lengthy, typically between two and four years. As a result, our future sales are highly dependent on our continued success at winning designs from our customers. Further, despite current inflationary and pricing conditions, unless we take actions to increase the prices of our products, we expect the ASPs of our products to decline over time, and we consider design wins to be critical to our future success as they help mitigate declines in ASPs. We anticipate being increasingly dependent on revenue from newer design wins for our newer products. The selection process is typically lengthy and may require us to incur significant design and development expenditures in pursuit of a design win, with no assurance that our solutions will be selected. As a result, the loss of any key design win or any significant delay in the ramp-up of volume production of a customer’s products into which our product is designed could adversely affect our business. In addition, volume production is contingent upon the successful introduction and market acceptance of our customers’ end products, which may be affected by several factors beyond our control.

Customer Demand, Orders and Forecasts

Demand for our products is highly dependent on market conditions in the end markets in which our customers operate, which are generally subject to seasonality, cyclicality, tariffs and other pricing increases and competitive conditions. In addition, a substantial portion of our total net sales is derived from sales to customers that purchase large volumes of our products. These customers generally provide periodic forecasts of their requirements. However, these forecasts do not commit such customers to minimum purchases, and customers can revise these forecasts without penalty. In addition, as is customary in the semiconductor industry, customers are generally permitted to cancel orders for our products within a specified period. Cancellations of orders could result in the loss of anticipated sales without allowing us sufficient time to reduce our inventory and operating expenses. In addition, changes in forecasts or the timing of orders from customers expose us to the risks of inventory shortages or excess inventory. These risks may be compounded by broader geopolitical and supply chain disruptions affecting the electronics supply chain, even when our own supply, manufacturing and distribution capabilities are unaffected. Because our products are incorporated into our customers’ end products alongside components and materials supplied by numerous third parties over whom we have no control, a shortage, trade restriction, geopolitical disruption or other event affecting any other critical component or input could cause our customers to delay, reduce, reschedule or cancel orders for our products, and we have observed that the effects of such disruptions may lag the underlying event by one or more quarters. We are currently operating in an inflationary environment for our products as a result of a rise in global energy and commodity prices and global tariff policies, which also have the potential to reduce end market demand in certain markets. Over the past several quarters, we and other semiconductor companies have experienced an increase in market demand, but historically such periods are often followed by periods of softening demand, primarily driven by lower demand from customers across various markets and digestion of excess accumulated inventory. In addition, factors that cause a reduction in demand from the end users of our OEM’s or other customers’ products, including as a result of increased prices resulting from a rise in global energy and commodity prices and global trade policies, tariffs or a recessionary environment in the markets in which we operate, may in the future continue to cause our direct customers to significantly reduce the number of products ordered from us.

Manufacturing Costs and Product Mix

Gross margin has been, and will continue to be, affected by a variety of factors, including the ASPs of our products, product mix in a given period, material costs, yields, manufacturing costs and efficiencies. We believe the primary driver of gross margin is the ASP negotiated between us and our customers relative to material costs and yields. Our pricing and margins depend on the volumes and the features of the products we produce and sell to our customers. As our products mature and unit volumes increase, we expect their ASPs to decline in the long-term. We continually monitor and work to reduce the cost of our products and improve the potential value our solutions provide to our customers, as we target new design win opportunities and manage the product life cycles of our existing customer designs. We also maintain a close relationship with our suppliers and subcontractors to improve quality, increase yields and lower manufacturing costs. As a result, these ASP declines often coincide with improvements in manufacturing yields and lower wafer, assembly, and testing costs, as well as selective price increases, which offset some or all of the margin reduction that results from declining ASPs. However, we expect our gross margin to fluctuate on a quarterly basis as a result of changes in ASPs due to product mix, new product introductions, transitions into volume manufacturing and manufacturing costs. Gross margin generally decreases if production volumes are lower as a result of decreased demand, which leads to a reduced absorption of our fixed manufacturing costs. Gross margin generally increases when the opposite occurs.

Cyclical Nature of the Semiconductor Industry

The semiconductor industry has historically been highly cyclical and is characterized by increasingly rapid technological change, product obsolescence, competitive pricing pressures, evolving standards, short product life cycles in consumer and other rapidly changing markets and fluctuations in product supply and demand. New technology may result in sudden changes in system designs or platform changes that may render some of our products obsolete and require us to devote significant research and development resources to compete effectively. Periods of rapid growth and capacityexpansion are occasionally followed by significant market corrections in which sales decline, inventories accumulate, and facilities go underutilized. Furthermore, emerging secular growth drivers and concentrated infrastructure investments, such as those supporting advanced computing, AI and data centers, and electrification, may alter the historical amplitude or duration of these industry cycles. During periods of expansion, our margins generally improve as fixed costs are spread over higher manufacturing volumes and unit sales. In addition, we may build inventory to meet increasing market demand for our products during these times, which serves to absorb fixed costs further and increase our gross margins. During an expansion cycle, we may increase capital spending and hiring to add to our production capacity. During periods of slower growth or industry contractions, our sales, production, productivity and margins generally decline.

Cost of goods sold as a percentage of our total net sales was 50.8% and 53.7% for the three-month periods ended
September 25, 2026 and September 26, 2025, respectively. The decrease was primarily due to the increase in net sales and favorable manufacturing absorption.

Gross profit and gross margin

Gross profit increased in the three-month period ended September 25, 2026 compared to the three-month period ended September 26, 2025, primarily due to the increase in net sales and favorable product mix.

Gross margin was 49.2% and 46.3% for the three-month periods ended September 25, 2026 and September 26, 2025, respectively. The increase was primarily due to the increase in net sales and a change in product mix and favorable manufacturing absorption.

Research and development expenses

Research and development (“R&D”) expenses increased in the three-month period ended September 25, 2026 compared to the three-month period ended September 26, 2025, primarily due to the increase in personnel costs and general operating expenses.

R&D expenses as a percentage of our total net sales were 20.1% and 23.7% for the three-month periods ended
September 25, 2026 and September 26, 2025, respectively. The decrease as a percentage of total net sales was primarily due to the increase in net sales, partially offset by the increase in personnel costs and general operating expenses.

Selling, general and administrative expenses

Selling, general and administrative (“SG&A”) expenses increased in the three-month period ended September 25, 2026 compared to the three-month period ended September 26, 2025, primarily due to an increase in personnel costs.

SG&A expenses as a percentage of our total net sales were 16.2% and 19.7% in the three-month periods ended
September 25, 2026 and September 26, 2025, respectively. The decrease as a percentage of total net sales was primarily due to the increase in net sales, partially offset by the increase in personnel costs.

Interest expense

Interest expense decreased in the three-month period ended September 25, 2026 compared to the three-month period ended September 26, 2025. The decrease was due to the voluntary payments applied to the outstanding balance of our term loans under our revolving credit facility (as described in Note 9, “Debt and Other Borrowings” to the unaudited condensed consolidated financial statements included in this Quarterly Report), in addition to the impact from refinancing the Company’s outstanding term loans under the Company’s revolving credit facility in January 2026.

Interest income

Interest income increased in the three-month period ended September 25, 2026 compared to the three-month period ended September 26, 2025, primarily due to higher cash and cash equivalents balances in interest-bearing accounts.

Other expense, net

The foreign currency loss recorded in the three-month period ended September 25, 2026 was primarily due to U.S. Dollar weakening against the Philippine Peso. The foreign currency loss recorded in the three-month period ended September 26, 2025 was primarily due to the U.S. Dollar weakening against various currencies, including the Euro and the Philippine Peso.

We recorded a net loss of $3.0 million and $2.4 million for the three-month periods ended September 25, 2026 and
September 26, 2025, respectively, related to our equity investment in Polar Semiconductor, LLC.

Income tax provision (benefit)

Taiwan net sales increased in the six-month period ended September 25, 2026 compared to the six-month period ended September 26, 2025, primarily driven by an increase in demand for our data center applications, partially offset by decrease in safety, comfort and convenience applications. Japan net sales increased primarily driven by safety, comfort and convenience applications, data center applications and Focus Auto. Greater China net sales increased primarily driven by an increase in internal combustion engine products, ADAS components, consumer products, and safety, comfort and convenience applications, partially offset by a decrease in broad-based industrial products. Other Asia net sales increased primarily due to an increase in demand for personal and industrial transport products. EMEA net sales increased primarily due to increases in consumer products and xEV components. South Korea net sales increased primarily due to an increase in demand for ADAS components and safety, comfort and convenience applications. United States net sales increased primarily due to increases in broad-based industrial products.

Cost of goods sold

Cost of goods sold increased in the six-month period ended September 25, 2026 compared to the six-month period ended September 26, 2025, primarily due to higher production volume in support of higher product sales.

Cost of goods sold as a percentage of our total net sales was 51.2% and 54.4% for the six-month periods ended
September 25, 2026 and September 26, 2025, respectively. The decrease was primarily due to the increase in net sales and favorable manufacturing absorption.

Gross profit and gross margin

Gross profit increased in the six-month period ended September 25, 2026 compared to the six-month period ended
September 26, 2025, primarily due to the increase in net sales and favorable product mix.

Gross margin was 48.8% and 45.6% for the six-month periods ended September 25, 2026 and September 26, 2025, respectively. The increase was primarily due to the increase in net sales and a change in product mix and favorable manufacturing absorption.

Research and development expenses

R&D expenses increased in the six-month period ended September 25, 2026 compared to the six-month period ended
September 26, 2025, primarily due to the increase in personnel costs, operating expenses and outside services.

R&D expenses as a percentage of our total net sales were 20.7% and 23.3% for the six-month periods ended
September 25, 2026 and September 26, 2025, respectively. The decrease as a percentage of total net sales was primarily due to the increase in net sales, partially offset by the increase in personnel costs, operating expenses and outside services.

Selling, general and administrative expenses

SG&A expenses increased in the six-month period ended September 25, 2026 compared to the six-month period ended September 26, 2025, primarily due to an increase in personnel costs, partially offset by a decrease in outside services.

SG&A expenses as a percentage of our total net sales were 16.8% and 21.5% in the six-month periods ended
September 25, 2026 and September 26, 2025, respectively. The decrease as a percentage of total net sales was primarily due to the increase in net sales, in addition to a decrease in outside services, partially offset by an increase in personnel costs.

Interest expense

Interest expense decreased in the six-month period ended September 25, 2026 compared to the six-month period ended September 26, 2025. The decrease was due to the voluntary payments applied to the outstanding balance of our term loans under our revolving credit facility, in addition to the impact from refinancing the Company’s outstanding term loans under the Company’s revolving credit facility in January 2026.

Interest income

Interest income increased in the six-month period ended September 25, 2026 compared to the six-month period ended September 26, 2025, primarily due to higher cash and cash equivalents balances in interest-bearing accounts.

Other expense, net

The foreign currency loss recorded in the six-month period ended September 25, 2026 was primarily due to the U.S. Dollar weakening against the Philippine Peso. The foreign currency loss recorded in the six-month period ended September 26, 2025 was primarily due to the U.S. Dollar weakening against various currencies, including the Euro and the Philippine Peso.

We recorded a net loss of $6.6 million and $3.2 million for the six-month periods ended September 25, 2026 and
September 26, 2025, respectively, related to our equity investment in Polar Semiconductor, LLC.

Income tax provision (benefit)

Income tax provision and the effective income tax rate were approximately $6.0 million and 13.3%, respectively, in the six-month period ended September 25, 2026, compared to income tax benefit and effective income tax rate of approximately $6.1 million and 48.2%, respectively, in the six-month period ended September 26, 2025. The change in the effective tax rates for the six-month periods primarily resulted from the significant increase in GAAP income before taxes, partially offset by the FDDEI deduction, stock-based compensation windfalls, and R&D credit benefits.

Liquidity and Capital Resources

As of September 25, 2026, we had $193.0 million of cash and cash equivalents and $425.1 million of working capital, compared to $168.8 million of cash and cash equivalents and $357.7 million of working capital as of March 27, 2026. Working capital is impacted by the timing and extent of our business needs.

Our primary requirements for liquidity and capital resources besides our growth initiatives are working capital, capital expenditures, principal and interest payments on our outstanding debt, and other general corporate needs. Historically, these cash requirements have been met through cash provided by operating activities and cash and cash equivalents. Our current capital deployment strategy for fiscal year 2027 is to utilize cash on hand and capacity under our revolving credit facility to support our continued growth initiatives into select markets and planned capital expenditures, as well as consider potential acquisitions. As of September 25, 2026, the Company was not party to any off-balance sheet arrangements that have had or are reasonably likely to have a current or future material effect on our financial condition, results of operations, liquidity, capital expenditures, or capital resources. The cash requirements for the current fiscal year relate to our operating leases, operating and capital purchase commitments, and expected contributions to our defined benefit and contribution plans. Additionally, we expect to continue to strategically invest in expanding our operations in China, Europe, Japan and India in order to directly manage and service our customers in these markets, which could result in increases in our total net sales, cost of goods sold and operating expenses. For information regarding the Company’s expected cash requirements and timing of payments related to leases, noncancellable purchase commitments and pension and defined contribution plans, see Note 12, “Leases,” Note 15, “Retirement Plans,” and Note 16, “Commitments and Contingencies” to the audited consolidated financial statements in the 2026 Annual Report.

We believe that our existing cash will be sufficient to finance our continued operations, growth strategy, planned capital expenditures and the additional expenses that we expect to incur during the next 12 months. In order to support and achieve our future growth plans, we may need or advantageously seek to obtain additional funding through equity or debt financing. We believe that our current operating structure will facilitate sufficient cash flows from operations to satisfy our expected long-term liquidity requirements beyond the next 12 months. If these resources are not sufficient to satisfy our liquidity requirements due to changes in circumstances, we may be required to borrow under our revolving credit facility or seek additional financing. If we raise additional funds by issuing equity securities that are not used to repurchase existing shares outstanding, our stockholders will experience dilution. Debt financing, if available, may contain covenants that significantly restrict our operations or our ability to obtain additional debt financing in the future. Any additional financing that we raise may contain terms that are not favorable to us or our stockholders. We cannot assure you that we would be able to obtain additional financing on terms favorable to us or our existing stockholders, or at all.

Cash Flows from Operating, Investing and Financing Activities

The following table summarizes our cash flows for the six-month periods ended September 25, 2026 and September 26, 2025:


	Six-Month Period Ended
	September 25, 2026			September 26, 2025
	(Dollars in thousands)
Net cash provided by operating activities	$	58,837		$	81,980
Net cash used in investing activities		(15,360	)		(17,044	)
Net cash used in financing activities		(16,899	)		(70,713	)
Effect of exchange rate changes on cash and cash equivalents and restricted cash		(834	)		1,484
Net increase (decrease) in cash and cash equivalents and restricted cash	$	25,744		$	(4,293	)

Operating Activities

Net cash provided by operating activities was $58.8 million in the six-month period ended September 25, 2026, resulting primarily from net income of $39.2 million and noncash charges of $67.5 million, further adjusted by a net decrease in cash from an increase in net operating assets and liabilities of $47.9 million. Noncash charges primarily included increases of $34.1 million for depreciation and amortization, $28.3 million of stock-based compensation, $6.6 million of loss in earnings of equity investment, and $2.3 million for provisions for inventory and expected credit losses, partially offset by $4.5 million of deferred income taxes. The net increase in operating assets and liabilities consisted of a $27.3 million decrease in other changes in operating assets and liabilities, net, a $20.0 million increase in payment to related party, a $2.2 million increase in inventories, a $15.2 million increase in trade accounts receivable, net, and a $1.2 million increase in net amounts due to and from related party, partially offset by a $12.3 million increase in trade accounts payable, and a $5.7 million decrease in prepaid expenses and other assets. The decrease in other changes in operating assets and liabilities, net was primarily the result of a reduction in accrued personnel costs due to the timing of the payments pursuant to our annual incentive compensation plan. The increase in payment to related party was primarily the result of advance payment on products. The increase in inventories was primarily the result of the increase in supplies to support future sales. The increase in trade accounts receivable, net was primarily a result of increased sales year-over-year and timing of collections. The increase in net amounts due to related party was primarily due to variations in the timing of such payments in the ordinary course of business. Trade accounts payable increased, primarily due to the timing of payments to suppliers and vendors, including unpaid capital expenditures of $2.0 million. The decrease in prepaid expenses and other assets was primarily due to the timing of tax payments.
