Summary of Significant Accounting Policies (Policies)	12 Months Ended
Mar. 29, 2025
Accounting Policies [Abstract]
Basis of Presentation	Basis of Presentation We prepare financial statements on a 52- or 53-week year that ends on the last Saturday in March. Fiscal years 2025 and 2023 were 52-week years. Fiscal year 2024 was a 53-week year.
Principles of Consolidation	Principles of Consolidation The accompanying consolidated financial statements have been prepared in accordance with U.S. generally accepted accounting principles (U.S. GAAP) and include the accounts of the Company and its wholly-owned subsidiaries. All significant intercompany balances and transactions have been eliminated.
Use of Estimates	Use of Estimates The preparation of financial statements in accordance with U.S. GAAP requires the use of management estimates. These estimates are subjective in nature and involve judgments that affect the reported amounts of assets and liabilities, the disclosure of contingent assets and liabilities at fiscal year-end and the reported amounts of revenue and expenses during the reporting period. Actual results could differ from these estimates.
Cash and Cash Equivalents	Cash and Cash Equivalents Cash and cash equivalents consist primarily of money market funds, U.S. Government Treasury and Agency instruments with original maturities of three months or less at the date of purchase.
Leases	Leases We account for leases under ASC 842, Leases. Our leases generally contain fixed rental payments, with additional variable payments linked to actual common area maintenance costs incurred by the landlord. These variable payments are not included within the lease liability and right-of-use ("ROU") asset, but are recognized as an expense when incurred. As our leases typically do not provide an implicit rate, the Company determines the Incremental Borrowing Rate ("IBR") for each lease based on the information available at the commencement date, taking into consideration necessary adjustments for collateral, currency, and lease term. Operating leases in excess of 12 months are recognized on the balance sheet, with future lease payments recognized as a liability, measured at present value, and the ROU asset recognized for the lease term. Lease expense is recognized in the income statement over the lease term.
Inventories	Inventories Inventories are stated at the lower of cost or net realizable value on a first-in, first-out basis. Cost is computed using standard costs, which approximate actual cost. One of the factors we consistently evaluate in the application of this method is the extent to which products are accepted into the marketplace. By policy, we evaluate market acceptance based on known business factors and conditions by comparing forecasted customer unit demand for our products over a specific future period, or demand horizon, to quantities on hand at the end of each accounting period. On a quarterly and annual basis, we analyze inventories on a part-by-part basis. Product life cycles and the competitive nature of the industry are factors considered in the evaluation of customer unit demand at the end of each quarterly accounting period. Inventory on-hand in excess of forecasted demand is considered to have reduced market value and, therefore, the cost basis is adjusted to net realizable value. Typically, market values for excess or obsolete inventories are considered to be zero. Inventory charges recorded for excess and obsolete inventory, including scrapped inventory, were $4.2 million in fiscal year 2025, related to a combination of quality issues and inventory exceeding demand. Net inventory reserve releases of $1.0 million in fiscal year 2024, primarily related to the sale of previously reserved inventory, offset by charges for excess and obsolete inventory.
Property, Plant and Equipment, net	Property, Plant and Equipment, net Property, plant and equipment is recorded at cost, net of depreciation and amortization. Depreciation and amortization is calculated on a straight-line basis over estimated economic lives, ranging from 3 to 39 years. Leasehold improvements are depreciated over the shorter of the term of the lease or the estimated useful life. Furniture, fixtures, machinery, and equipment are all depreciated over a useful life of 3 to 10 years, while buildings are depreciated over a period of up to 39 years. In general, our capitalized software is amortized over a useful life of 3 years, with capitalized enterprise resource planning software being amortized over a useful life of 10 years. Gains or losses related to retirements or dispositions of fixed assets are recognized in the period incurred. Additionally, if impairment indicators exist, the Company will assess the carrying value in relation to the calculated fair value of the associated asset.
Goodwill	Goodwill Goodwill is recorded at the time of an acquisition and is calculated as the difference between the aggregate consideration paid for an acquisition and the fair value of the net tangible and intangible assets acquired. The Company tests goodwill for impairment on an annual basis or more frequently if the Company believes indicators of impairment exist. Impairment evaluations involve management’s assessment of qualitative factors to determine whether it is more likely than not that goodwill is impaired. If management concludes from its assessment of qualitative factors that it is more likely than not that impairment exists, then a quantitative impairment test will be performed involving management estimates of future cash flows. Significant management judgment is required in the forecasts of future operating results that are used in these evaluations. Following the quantitative test, an impairment charge would be recorded for the amount the carrying value exceeds the calculated fair value.
Long-Lived Assets	Long-Lived Assets Intangible assets include purchased technology licenses and patents that are reported at cost and are amortized on a straight-line basis over their useful lives, generally ranging from 1 to 5 years. Acquired intangibles include existing technology, core technology or patents, license agreements, in-process research & development, trademarks, tradenames, customer relationships, and non-compete agreements. These assets are amortized on a straight-line basis over lives ranging from 1 to 15 years. We regularly review whether facts or circumstances exist that indicate the carrying values of property, plant and equipment or other long-lived assets, including intangible assets, are impaired. We assess the recoverability of assets by comparing the projected undiscounted net cash flows associated with those assets to their respective carrying amounts. We measure any impairment loss by comparing the fair value of the asset to its carrying amount. We estimate fair value based on discounted future cash flows, quoted market prices, or independent appraisals. See Note 7 — Intangibles, net and Goodwill for further detail. There were no material intangible asset impairments recorded in fiscal years 2025 or 2024.
Foreign Currency Translation	Foreign Currency Translation Some of the Company's subsidiaries utilize the local currency as the functional currency. The Company’s main entities, including the entities that generate the majority of sales and employ the majority of employees, are U.S. dollar functional.
Concentration of Credit Risk	Concentration of Credit Risk Financial instruments that potentially subject us to material concentrations of credit risk consist primarily of cash equivalents, marketable securities, long-term marketable securities, and trade accounts receivable. We are exposed to credit risk to the extent of the amounts recorded on the balance sheet. By policy, our cash equivalents, marketable securities, and long-term marketable securities are subject to certain nationally recognized credit standards, issuer concentrations, sovereign risk, and marketability or liquidity considerations. In evaluating our trade receivables, we perform credit evaluations of our major customers’ financial condition and monitor closely all of our receivables to limit our financial exposure by limiting the length of time and amount of credit extended. In certain situations, we may require payment in advance or utilize letters of credit to reduce credit risk. By policy, we establish a reserve for trade accounts receivable based on the type of business in which a customer is engaged, the length of time a trade account receivable is outstanding, and other knowledge that we may possess relating to the probability that a trade receivable is at risk for non-payment. We had two contract manufacturers aggregated at their parent level, Foxconn and Luxsan, who represented 41 percent and 21 percent, respectively, of our consolidated gross trade accounts receivable as of the end of fiscal year 2025. We had three contract manufacturers aggregated at their parent level, Foxconn, Luxshare Precision, and Pegatron, who represented 43 percent, 11 percent, and 10 percent, respectively, of our consolidated gross trade accounts receivable as of the end of fiscal year 2024. No other distributor or contract manufacturer had receivable balances that represented more than 10 percent of consolidated gross trade accounts receivable as of the end of fiscal year 2025 or 2024. Since the components we produce are largely proprietary and generally not available from second sources, we consider our end customer to be the entity specifying the use of our component in their design. These end customers may then purchase our products directly from us, from a distributor, or through a third-party manufacturer contracted to produce their end product. For fiscal years 2025, 2024 and 2023, our ten largest end customers represented approximately 96 percent, 95 percent and 92 percent of our net sales, respectively. For fiscal years 2025, 2024, and 2023, we had one end customer, Apple Inc., who purchased through multiple contract manufacturers and represented approximately 89 percent, 87 percent, and 83 percent, of the Company’s total net sales, respectively. No other customer or distributor represented more than 10 percent of net sales in fiscal years 2025, 2024, or 2023.
Revenue Recognition, Shipping Costs	Revenue Recognition We recognize revenue upon the transfer of promised goods or services to customers, in an amount that reflects the consideration the Company expects to be entitled in exchange for those goods or services. Performance Obligations The Company’s single performance obligation is the delivery of promised goods to the customer. The promised goods are explicitly stated in the customer contract and are comprised of a single type of good. This performance obligation is satisfied upon transfer of control of the promised goods to the customer, as defined per the shipping terms within the customer’s contract. The vast majority of the Company’s contracts with customers have an original expected term of one year or less. Contract balances Payments are typically due within 30 to 60 days of invoicing and terms do not include a significant financing component or noncash consideration. There have been no material impairment losses on accounts receivable. There are no material contract liabilities recorded on the consolidated balance sheets. Transaction price The transaction price is the amount of consideration to which the Company expects to be entitled in exchange for transferring the promised goods to the customer. Fixed pricing is the consideration that is agreed upon in the customer contract. Variable pricing includes rights of return, price protection and stock rotation. Rights of return costs are estimated using the "most likely amount" method by reviewing historical returns to determine the most likely customer return rate and applying materiality thresholds. Price protection includes price adjustments available to certain distributors based upon established book price and a stated adjustment period. Stock rotation is also available to certain distributors based on a stated maximum of prior billings. The Company estimates all variable consideration at the most likely amount which it expects to be entitled. The estimate is based on current and historical information available to the Company, including recent sales activity and pricing. Variable consideration is only included in the transaction price to the extent that it is probable that a significant reversal in the amount of cumulative revenue recognized will not occur when the uncertainty associated with the variable consideration is resolved. The Company defers all variable consideration that does not meet the revenue recognition criteria. Shipping Costs Our shipping and handling costs are included in cost of sales for all periods presented in the consolidated statements of income. Disaggregation of revenue We disaggregate revenue from contracts with customers by product line and ship to location of the customer. Sales are designated in the product line categories of Audio and High-Performance Mixed-Signal ("HPMS").
Advertising Costs	Advertising Costs Advertising costs are expensed as incurred.
Stock-Based Compensation	Stock-Based Compensation Stock-based compensation is measured at the grant date based on the grant-date fair value of the awards and is recognized as an expense, on a ratable basis, over the vesting period, which is generally between 1 and 4 years. Determining the amount of stock-based compensation to be recorded requires the Company to develop estimates used in calculating the grant-date fair value of stock options and market stock units. The Company calculates the grant-date fair value for stock options and market stock units ("MSUs") using the Black-Scholes valuation model and the Monte Carlo simulation, respectively. The use of valuation models requires the Company to make estimates of assumptions such as expected volatility, expected term, risk-free interest rate, expected dividend yield, and forfeiture rates. The grant-date fair value of restricted stock units ("RSUs") is the market value at grant date multiplied by the number of units. The grant-date fair value of performance stock units ("PSUs") is the market value at grant date multiplied by the target number of award units.
Income Taxes	Income Taxes We are required to calculate income taxes in each of the jurisdictions in which we operate. This process involves calculating the actual current tax liability as well as assessing temporary differences in the recognition of income or loss for tax and accounting purposes. These differences result in deferred tax assets and liabilities, which are included in our consolidated balance sheet. We record a valuation allowance when it is more likely than not that some portion or all of the deferred tax assets will not be realized. The Company evaluates the ability to realize its deferred tax assets based on all the facts and circumstances, including projections of future taxable income and expiration dates of carryover tax attributes. The calculation of our tax liabilities involves assessing uncertainties with respect to the application of complex tax rules and the potential for future adjustment of our uncertain tax positions by the U.S. Internal Revenue Service or other taxing jurisdiction. We recognize liabilities for uncertain tax positions based on the required two-step process. The first step requires us to determine if the weight of available evidence indicates that the tax position has met the threshold for recognition; therefore, we must evaluate whether it is more likely than not that the position will be sustained on audit, including resolution of any related appeals or litigation processes. The second step requires us to measure the tax benefit of the tax position taken, or expected to be taken, in an income tax return as the largest amount that is more than 50 percent likely of being realized upon ultimate settlement. We reevaluate the uncertain tax positions each quarter based on factors including, but not limited to, changes in facts or circumstances, changes in tax law, expirations of statutes of limitation, effectively settled issues under audit, and new audit activity. A change in the recognition step or measurement step would result in the recognition of a tax benefit or an additional charge to the tax provision in the period. Although we believe the measurement of our liabilities for uncertain tax positions is reasonable, we cannot assure that the final outcome of these matters will not be different than what is reflected in the historical income tax provisions and accruals. If additional taxes are assessed as a result of an audit or litigation, it could have a material effect on our income tax provision and net income in the period or periods for which that determination is made. We operate within multiple taxing jurisdictions and are subject to audit in these jurisdictions. These audits can involve complex issues which may require an extended period of time to resolve and could result in additional assessments of income tax. We believe adequate provisions for income taxes have been made for all periods. See Note 17 - Income Taxes for further detail. Government Assistance The Company benefits from the Research and Development Expenditure Credit (“RDEC”) program in the United Kingdom. The RDEC is recorded as an offset to research and development expenses in the consolidated statements of income, $43.0 million, $40.9 million, and $26.2 million in fiscal years 2025, 2024, and 2023, respectively. The RDEC is first settled against the Company's United Kingdom quarterly income tax payments with any remainder paid in cash on an annual basis. The RDEC receivable as of March 30, 2024 totaled $27.9 million, presented within "Other current Assets" on the consolidated balance sheets. There was no RDEC receivable as of March 29, 2025. While the duration of RDEC benefits is indefinite, the program is subject to future policy changes and RDEC claims are subject to regular audits by the United Kingdom government.
Net Income Per Share	Net Income Per Share Basic net income per share is based on the weighted effect of common shares issued and outstanding and is calculated by dividing net income by the basic weighted average shares outstanding during the period. Diluted net income per share is calculated by dividing net income by the weighted average number of common shares used in the basic net income per share calculation, plus the equivalent number of common shares that would be issued assuming exercise or conversion of all potentially dilutive common shares outstanding. These potentially dilutive items consist primarily of outstanding stock options and restricted stock grants.
Accumulated Other Comprehensive Loss	Accumulated Other Comprehensive Loss Our accumulated other comprehensive loss is comprised of foreign currency translation adjustments and unrealized gains and losses on investments classified as available-for-sale. See Note 16 — Accumulated Other Comprehensive Loss for additional discussion.
Recently Adopted Accounting Pronouncements / Recently Issued Accounting Pronouncements	Recently Adopted Accounting Pronouncements In November 2023, the FASB issued ASU 2023-07, Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures. This ASU requires interim and annual disclosure of significant segment expenses that are regularly provided to the CODM and included within each reported measure of a segment’s profit or loss, requires interim disclosures about a reportable segment’s profit or loss and assets that are currently required annually and requires disclosure of the position and title of the CODM and how the CODM uses segment profit or loss information in assessing segment performance and deciding how to allocate resources. In the event the CODM uses more than one measure of a segment's profit or loss in assessing performance and allocation of resources, clarification of disclosure requirements is provided. Additionally, a company with a single reportable segment is required to provide all the disclosures prescribed under this ASU. The guidance is effective for annual periods beginning after December 15, 2023, and interim periods within fiscal years beginning after December 15, 2024, to be applied retrospectively to all periods presented. The Company retrospectively adopted this standard for the fiscal year ending March 29, 2025. See Note 18 - Segment Information. The adoption of this standard had no impact on our results of operations, cash flows or financial position. Recently Issued Accounting Pronouncements In December 2023, the FASB issued ASU 2023-09, Income Taxes (Topic 740) - Improvements to Income Tax Disclosures. The guidance provides qualitative and quantitative updates to the rate reconciliation and income taxes paid disclosures, requiring more consistent categories and greater disaggregation of information by jurisdiction. This ASU is effective for financial statements issued for annual periods beginning after December 15, 2024, with early adoption permitted, to be applied on a prospective basis, although retrospective application is also permitted. The Company is currently evaluating the impact of this guidance on financial statement disclosures. In November 2024, FASB issued ASU 2024-03, Income Statement - Reporting Comprehensive Income - Expense Disaggregation Disclosures (Topic 220-40): Disaggregation of Income Statement Expenses, which requires disaggregation of certain expense categories in the notes to the financial statements in order to provide enhanced transparency into the expense captions presented on the face of the income statement. The amendments are effective for fiscal years beginning after December 15, 2026, and interim periods within fiscal years beginning after December 15, 2027, with early adoption and prospective or retrospective application permitted. The Company is currently evaluating the impact of this guidance on financial statement disclosures.
Marketable Securities	The Company’s investments have been classified as available-for-sale securities in accordance with U.S. GAAP. Marketable securities are categorized on the consolidated balance sheet as “Marketable securities” within the short-term or long-term classification, as appropriate.
Fair Value of Financial Instruments	The Company has determined that the assets and liabilities in the Company’s financial statements that are required to be measured at fair value on a recurring basis are the Company’s cash equivalents and marketable securities portfolio. The Company defines fair value as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. The Company applies the following fair value hierarchy, which prioritizes the inputs used to measure fair value into three levels and bases the categorization within the hierarchy upon the lowest level of input that is available and significant to the fair value measurement. The hierarchy gives the highest priority to unadjusted quoted prices in active markets for identical assets or liabilities (Level 1 measurements) and the lowest priority to unobservable inputs (Level 3 measurements). ▪Level 1 — Quoted prices in active markets for identical assets or liabilities. ▪Level 2 — Inputs other than Level 1 that are observable, either directly or indirectly, such as quoted prices for similar assets or liabilities; quoted prices in markets that are not active; or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the assets or liabilities. ▪Level 3 — Unobservable inputs that are supported by little or no market activity and that are significant to the fair value of the assets or liabilities. The Company’s cash equivalents and marketable securities portfolio consist of money market funds, commercial paper, debt securities, non-U.S government securities, U.S Treasury securities, and securities of U.S. government-sponsored enterprises, and are reflected on our consolidated balance sheet under the headings cash and cash equivalents, marketable securities, and long-term marketable securities. The Company determines the fair value of its marketable securities portfolio by obtaining non-binding market prices from its third-party pricing providers on the last day of the quarter, whose sources may use quoted prices in active markets for identical assets (Level 1 inputs) or inputs other than quoted prices that are observable either directly or indirectly (Level 2 inputs) in determining fair value
Segment Information	We determine our operating segments in accordance with Financial Accounting Standards Board (“FASB”) guidelines. Our Chief Executive Officer (“CEO”) has been identified as the CODM under these guidelines. The Company operates and tracks its results in one reportable segment, but reports revenue performance in two product lines: Audio and HPMS. Our CEO receives and uses enterprise-wide financial information to assess financial performance and allocate resources. Our product lines have similar characteristics and customers and share operations support functions such as sales, public relations, supply chain management, various research and development and engineering support, in addition to the general and administrative functions of human resources, legal, finance and information technology. Therefore, there is no complete, discrete financial information maintained for these product lines. Revenue by product line is disclosed in Note 9 - Revenues.

Summary of Significant Accounting Policies (Policies)

12 Months Ended

Mar. 29, 2025

We prepare financial statements on a 52- or 53-week year that ends on the last Saturday in March. Fiscal years 2025 and 2023 were 52-week years. Fiscal year 2024 was a 53-week year.

Principles of Consolidation

The accompanying consolidated financial statements have been prepared in accordance with U.S. generally accepted accounting principles (U.S. GAAP) and include the accounts of the Company and its wholly-owned subsidiaries. All significant intercompany balances and transactions have been eliminated.

Use of Estimates

The preparation of financial statements in accordance with U.S. GAAP requires the use of management estimates. These estimates are subjective in nature and involve judgments that affect the reported amounts of assets and liabilities, the disclosure of contingent assets and liabilities at fiscal year-end and the reported amounts of revenue and expenses during the reporting period. Actual results could differ from these estimates.

Cash and Cash Equivalents

Cash and cash equivalents consist primarily of money market funds, U.S. Government Treasury and Agency instruments with original maturities of three months or less at the date of purchase.

Leases

We account for leases under ASC 842, Leases. Our leases generally contain fixed rental payments, with additional variable payments linked to actual common area maintenance costs incurred by the landlord. These variable payments are not included within the lease liability and right-of-use ("ROU") asset, but are recognized as an expense when incurred. As our leases typically do not provide an implicit rate, the Company determines the Incremental Borrowing Rate ("IBR") for each lease based on the information available at the commencement date, taking into consideration necessary adjustments for collateral, currency, and lease term.

Operating leases in excess of 12 months are recognized on the balance sheet, with future lease payments recognized as a liability, measured at present value, and the ROU asset recognized for the lease term. Lease expense is recognized in the income statement over the lease term.

Inventories

Inventories are stated at the lower of cost or net realizable value on a first-in, first-out basis. Cost is computed using standard costs, which approximate actual cost. One of the factors we consistently evaluate in the application of this method is the extent to which products are accepted into the marketplace. By policy, we evaluate market acceptance based on known business factors and conditions by comparing forecasted customer unit demand for our products over a specific future period, or demand horizon, to quantities on hand at the end of each accounting period.

On a quarterly and annual basis, we analyze inventories on a part-by-part basis. Product life cycles and the competitive nature of the industry are factors considered in the evaluation of customer unit demand at the end of each quarterly accounting

period. Inventory on-hand in excess of forecasted demand is considered to have reduced market value and, therefore, the cost basis is adjusted to net realizable value. Typically, market values for excess or obsolete inventories are considered to be zero. Inventory charges recorded for excess and obsolete inventory, including scrapped inventory, were $4.2 million in fiscal year 2025, related to a combination of quality issues and inventory exceeding demand. Net inventory reserve releases of $1.0 million in fiscal year 2024, primarily related to the sale of previously reserved inventory, offset by charges for excess and obsolete inventory.

Property, Plant and Equipment, net

Property, plant and equipment is recorded at cost, net of depreciation and amortization. Depreciation and amortization is calculated on a straight-line basis over estimated economic lives, ranging from 3 to 39 years. Leasehold improvements are depreciated over the shorter of the term of the lease or the estimated useful life. Furniture, fixtures, machinery, and equipment are all depreciated over a useful life of 3 to 10 years, while buildings are depreciated over a period of up to 39 years. In general, our capitalized software is amortized over a useful life of 3 years, with capitalized enterprise resource planning software being amortized over a useful life of 10 years. Gains or losses related to retirements or dispositions of fixed assets are recognized in the period incurred. Additionally, if impairment indicators exist, the Company will assess the carrying value in relation to the calculated fair value of the associated asset.

Goodwill

Goodwill is recorded at the time of an acquisition and is calculated as the difference between the aggregate consideration paid for an acquisition and the fair value of the net tangible and intangible assets acquired. The Company tests goodwill for impairment on an annual basis or more frequently if the Company believes indicators of impairment exist. Impairment evaluations involve management’s assessment of qualitative factors to determine whether it is more likely than not that goodwill is impaired. If management concludes from its assessment of qualitative factors that it is more likely than not that impairment exists, then a quantitative impairment test will be performed involving management estimates of future cash flows. Significant management judgment is required in the forecasts of future operating results that are used in these evaluations. Following the quantitative test, an impairment charge would be recorded for the amount the carrying value exceeds the calculated fair value.

Long-Lived Assets

Intangible assets include purchased technology licenses and patents that are reported at cost and are amortized on a straight-line basis over their useful lives, generally ranging from 1 to 5 years. Acquired intangibles include existing technology, core technology or patents, license agreements, in-process research & development, trademarks, tradenames, customer relationships, and non-compete agreements. These assets are amortized on a straight-line basis over lives ranging from 1 to 15 years.

We regularly review whether facts or circumstances exist that indicate the carrying values of property, plant and equipment or other long-lived assets, including intangible assets, are impaired. We assess the recoverability of assets by comparing the projected undiscounted net cash flows associated with those assets to their respective carrying amounts. We measure any impairment loss by comparing the fair value of the asset to its carrying amount. We estimate fair value based on discounted future cash flows, quoted market prices, or independent appraisals. See Note 7 — Intangibles, net and Goodwill for further detail. There were no material intangible asset impairments recorded in fiscal years 2025 or 2024.

Foreign Currency Translation

Some of the Company's subsidiaries utilize the local currency as the functional currency. The Company’s main entities, including the entities that generate the majority of sales and employ the majority of employees, are U.S. dollar functional.

Concentration of Credit Risk

Financial instruments that potentially subject us to material concentrations of credit risk consist primarily of cash equivalents, marketable securities, long-term marketable securities, and trade accounts receivable. We are exposed to credit risk to the extent of the amounts recorded on the balance sheet. By policy, our cash equivalents, marketable securities, and long-term marketable securities are subject to certain nationally recognized credit standards, issuer concentrations, sovereign risk, and marketability or liquidity considerations.

In evaluating our trade receivables, we perform credit evaluations of our major customers’ financial condition and monitor closely all of our receivables to limit our financial exposure by limiting the length of time and amount of credit extended. In certain situations, we may require payment in advance or utilize letters of credit to reduce credit risk. By policy, we establish a reserve for trade accounts receivable based on the type of business in which a customer is engaged, the length of time a trade account receivable is outstanding, and other knowledge that we may possess relating to the probability that a trade receivable is at risk for non-payment.

We had two contract manufacturers aggregated at their parent level, Foxconn and Luxsan, who represented 41 percent and 21 percent, respectively, of our consolidated gross trade accounts receivable as of the end of fiscal year 2025. We had three contract manufacturers aggregated at their parent level, Foxconn, Luxshare Precision, and Pegatron, who represented 43 percent, 11 percent, and 10 percent, respectively, of our consolidated gross trade accounts receivable as of the end of fiscal year 2024. No other distributor or contract manufacturer had receivable balances that represented more than 10 percent of consolidated gross trade accounts receivable as of the end of fiscal year 2025 or 2024.

Since the components we produce are largely proprietary and generally not available from second sources, we consider our end customer to be the entity specifying the use of our component in their design. These end customers may then purchase our products directly from us, from a distributor, or through a third-party manufacturer contracted to produce their end product. For fiscal years 2025, 2024 and 2023, our ten largest end customers represented approximately 96 percent, 95 percent and 92 percent of our net sales, respectively. For fiscal years 2025, 2024, and 2023, we had one end customer, Apple Inc., who purchased through multiple contract manufacturers and represented approximately 89 percent, 87 percent, and 83 percent, of the Company’s total net sales, respectively. No other customer or distributor represented more than 10 percent of net sales in fiscal years 2025, 2024, or 2023.

Revenue Recognition, Shipping Costs

Revenue Recognition

We recognize revenue upon the transfer of promised goods or services to customers, in an amount that reflects the consideration the Company expects to be entitled in exchange for those goods or services.

Performance Obligations

The Company’s single performance obligation is the delivery of promised goods to the customer. The promised goods are explicitly stated in the customer contract and are comprised of a single type of good. This performance obligation is satisfied upon transfer of control of the promised goods to the customer, as defined per the shipping terms within the customer’s contract. The vast majority of the Company’s contracts with customers have an original expected term of one year or less.

Contract balances

Payments are typically due within 30 to 60 days of invoicing and terms do not include a significant financing component or noncash consideration. There have been no material impairment losses on accounts receivable. There are no material contract liabilities recorded on the consolidated balance sheets.

Transaction price

The transaction price is the amount of consideration to which the Company expects to be entitled in exchange for transferring the promised goods to the customer. Fixed pricing is the consideration that is agreed upon in the customer contract. Variable pricing includes rights of return, price protection and stock rotation. Rights of return costs are estimated using the "most likely amount" method by reviewing historical returns to determine the most likely customer return rate and applying materiality thresholds. Price protection includes price adjustments available to certain distributors based upon established book price and a stated adjustment period. Stock rotation is also available to certain distributors based on a stated maximum of prior billings.

The Company estimates all variable consideration at the most likely amount which it expects to be entitled. The estimate is based on current and historical information available to the Company, including recent sales activity and pricing. Variable consideration is only included in the transaction price to the extent that it is probable that a significant reversal in the amount of cumulative revenue recognized will not occur when the uncertainty associated with the variable consideration is resolved. The Company defers all variable consideration that does not meet the revenue recognition criteria.

Shipping Costs

Our shipping and handling costs are included in cost of sales for all periods presented in the consolidated statements of income.

Disaggregation of revenue

We disaggregate revenue from contracts with customers by product line and ship to location of the customer. Sales are designated in the product line categories of Audio and High-Performance Mixed-Signal ("HPMS").

Advertising Costs

Advertising costs are expensed as incurred.

Stock-Based Compensation

Stock-based compensation is measured at the grant date based on the grant-date fair value of the awards and is recognized as an expense, on a ratable basis, over the vesting period, which is generally between 1 and 4 years. Determining the amount of stock-based compensation to be recorded requires the Company to develop estimates used in calculating the grant-date fair value of stock options and market stock units. The Company calculates the grant-date fair value for stock options and market stock units ("MSUs") using the Black-Scholes valuation model and the Monte Carlo simulation, respectively. The use of valuation models requires the Company to make estimates of assumptions such as expected volatility, expected term, risk-free interest rate, expected dividend yield, and forfeiture rates. The grant-date fair value of restricted stock units ("RSUs") is the market value at grant date multiplied by the number of units. The grant-date fair value of performance stock units ("PSUs") is the market value at grant date multiplied by the target number of award units.

Income Taxes

We are required to calculate income taxes in each of the jurisdictions in which we operate. This process involves calculating the actual current tax liability as well as assessing temporary differences in the recognition of income or loss for tax and accounting purposes. These differences result in deferred tax assets and liabilities, which are included in our consolidated balance sheet. We record a valuation allowance when it is more likely than not that some portion or all of the deferred tax assets will not be realized. The Company evaluates the ability to realize its deferred tax assets based on all the facts and circumstances, including projections of future taxable income and expiration dates of carryover tax attributes.

The calculation of our tax liabilities involves assessing uncertainties with respect to the application of complex tax rules and the potential for future adjustment of our uncertain tax positions by the U.S. Internal Revenue Service or other taxing jurisdiction. We recognize liabilities for uncertain tax positions based on the required two-step process. The first step requires us to determine if the weight of available evidence indicates that the tax position has met the threshold for recognition; therefore, we must evaluate whether it is more likely than not that the position will be sustained on audit, including resolution of any related appeals or litigation processes. The second step requires us to measure the tax benefit of the tax position taken, or expected to be taken, in an income tax return as the largest amount that is more than 50 percent likely of being realized upon ultimate settlement. We reevaluate the uncertain tax positions each quarter based on factors including, but not limited to, changes in facts or circumstances, changes in tax law, expirations of statutes of limitation, effectively settled issues under audit, and new audit activity. A change in the recognition step or measurement step would result in the recognition of a tax benefit or an additional charge to the tax provision in the period.

Although we believe the measurement of our liabilities for uncertain tax positions is reasonable, we cannot assure that the final outcome of these matters will not be different than what is reflected in the historical income tax provisions and accruals. If additional taxes are assessed as a result of an audit or litigation, it could have a material effect on our income tax provision and net income in the period or periods for which that determination is made. We operate within multiple taxing jurisdictions and are subject to audit in these jurisdictions. These audits can involve complex issues which may require an extended period of time to resolve and could result in additional assessments of income tax. We believe adequate provisions for income taxes have been made for all periods. See Note 17 - Income Taxes for further detail.

Government Assistance

The Company benefits from the Research and Development Expenditure Credit (“RDEC”) program in the United Kingdom. The RDEC is recorded as an offset to research and development expenses in the consolidated statements of income, $43.0 million, $40.9 million, and $26.2 million in fiscal years 2025, 2024, and 2023, respectively. The RDEC is first settled against the Company's United Kingdom quarterly income tax payments with any remainder paid in cash on an annual basis. The RDEC receivable as of March 30, 2024 totaled $27.9 million, presented within "Other current Assets" on the consolidated balance sheets. There was no RDEC receivable as of March 29, 2025. While the duration of RDEC benefits is indefinite, the program is subject to future policy changes and RDEC claims are subject to regular audits by the United Kingdom government.

Net Income Per Share

Basic net income per share is based on the weighted effect of common shares issued and outstanding and is calculated by dividing net income by the basic weighted average shares outstanding during the period. Diluted net income per share is calculated by dividing net income by the weighted average number of common shares used in the basic net income per share calculation, plus the equivalent number of common shares that would be issued assuming exercise or conversion of all potentially dilutive common shares outstanding. These potentially dilutive items consist primarily of outstanding stock options and restricted stock grants.

Accumulated Other Comprehensive Loss

Our accumulated other comprehensive loss is comprised of foreign currency translation adjustments and unrealized gains and losses on investments classified as available-for-sale. See Note 16 — Accumulated Other Comprehensive Loss for additional discussion.

Recently Adopted Accounting Pronouncements

In November 2023, the FASB issued ASU 2023-07, Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures. This ASU requires interim and annual disclosure of significant segment expenses that are regularly provided to the CODM and included within each reported measure of a segment’s profit or loss, requires interim disclosures about a reportable segment’s profit or loss and assets that are currently required annually and requires disclosure of the position and title of the CODM and how the CODM uses segment profit or loss information in assessing segment performance and deciding how to allocate resources. In the event the CODM uses more than one measure of a segment's profit or loss in assessing performance and allocation of resources, clarification of disclosure requirements is provided. Additionally, a company with a single reportable segment is required to provide all the disclosures prescribed under this ASU. The guidance is

effective for annual periods beginning after December 15, 2023, and interim periods within fiscal years beginning after December 15, 2024, to be applied retrospectively to all periods presented. The Company retrospectively adopted this standard for the fiscal year ending March 29, 2025. See Note 18 - Segment Information. The adoption of this standard had no impact on our results of operations, cash flows or financial position.

Recently Issued Accounting Pronouncements

In December 2023, the FASB issued ASU 2023-09, Income Taxes (Topic 740) - Improvements to Income Tax Disclosures. The guidance provides qualitative and quantitative updates to the rate reconciliation and income taxes paid disclosures, requiring more consistent categories and greater disaggregation of information by jurisdiction. This ASU is effective for financial statements issued for annual periods beginning after December 15, 2024, with early adoption permitted, to be applied on a prospective basis, although retrospective application is also permitted. The Company is currently evaluating the impact of this guidance on financial statement disclosures.

In November 2024, FASB issued ASU 2024-03, Income Statement - Reporting Comprehensive Income - Expense Disaggregation Disclosures (Topic 220-40): Disaggregation of Income Statement Expenses, which requires disaggregation of certain expense categories in the notes to the financial statements in order to provide enhanced transparency into the expense captions presented on the face of the income statement. The amendments are effective for fiscal years beginning after December 15, 2026, and interim periods within fiscal years beginning after December 15, 2027, with early adoption and prospective or retrospective application permitted. The Company is currently evaluating the impact of this guidance on financial statement disclosures.

Marketable Securities

The Company’s investments have been classified as available-for-sale securities in accordance with U.S. GAAP. Marketable securities are categorized on the consolidated balance sheet as “Marketable securities” within the short-term or long-term classification, as appropriate.

Fair Value of Financial Instruments

The Company has determined that the assets and liabilities in the Company’s financial statements that are required to be measured at fair value on a recurring basis are the Company’s cash equivalents and marketable securities portfolio. The Company defines fair value as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. The Company applies the following fair value hierarchy, which prioritizes the inputs used to measure fair value into three levels and bases the categorization within the hierarchy upon the lowest level of input that is available and significant to the fair value measurement. The hierarchy gives the highest priority to unadjusted quoted prices in active markets for identical assets or liabilities (Level 1 measurements) and the lowest priority to unobservable inputs (Level 3 measurements).

▪Level 1 — Quoted prices in active markets for identical assets or liabilities.

▪Level 2 — Inputs other than Level 1 that are observable, either directly or indirectly, such as quoted prices for similar assets or liabilities; quoted prices in markets that are not active; or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the assets or liabilities.

▪Level 3 — Unobservable inputs that are supported by little or no market activity and that are significant to the fair value of the assets or liabilities.

The Company’s cash equivalents and marketable securities portfolio consist of money market funds, commercial paper, debt securities, non-U.S government securities, U.S Treasury securities, and securities of U.S. government-sponsored enterprises, and are reflected on our consolidated balance sheet under the headings cash and cash equivalents, marketable securities, and long-term marketable securities. The Company determines the fair value of its marketable securities portfolio by obtaining non-binding market prices from its third-party pricing providers on the last day of the quarter, whose sources may use quoted prices in active markets for identical assets (Level 1 inputs) or inputs other than quoted prices that are observable either directly or indirectly (Level 2 inputs) in determining fair value

Segment Information

We determine our operating segments in accordance with Financial Accounting Standards Board (“FASB”) guidelines. Our Chief Executive Officer (“CEO”) has been identified as the CODM under these guidelines.

The Company operates and tracks its results in one reportable segment, but reports revenue performance in two product lines: Audio and HPMS. Our CEO receives and uses enterprise-wide financial information to assess financial performance and allocate resources. Our product lines have similar characteristics and customers and share operations support functions such as sales, public relations, supply chain management, various research and development and engineering support, in addition to the general and administrative functions of human resources, legal, finance and information technology. Therefore, there is no complete, discrete financial information maintained for these product lines. Revenue by product line is disclosed in Note 9 - Revenues.
