FORWARD-LO OKING 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 29, 2024, filed with the Securities and Exchange Commission (“SEC”) on May 23, 2024 (the “2024 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 designing, developing and manufacturing sensing and power solutions for motion control and energy-efficient systems in automotive and industrial and other markets. 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 Company’s Annual Report on Form 10-K for the year ended March 29, 2024. The March 29, 2024 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 third quarter three-month period is a 13-week period. The Company’s third quarter of fiscal year 2025 ended December 27, 2024, and the Company’s third quarter of fiscal year 2024 ended December 29, 2023.

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 December 27, 2024, one distributor accounted for 11.2% of the Company’s outstanding trade accounts receivable, net. As of March 29, 2024, no distributor or customer accounted for 10% or more of the Company’s outstanding trade accounts receivable, net.

For the three-month period ended December 27, 2024, one distributor accounted for 11.4% of total net sales. No other distributor or customer accounted for 10% or more of total net sales for the nine-month period ended December 27, 2024. For the nine-month period ended December 29, 2023, one distributor customer accounted for 11.0% of total net sales. No other distributor or customer accounted for 10% or more of total net sales for the three-month period ended December 29, 2023.

Recent Accounting Pronouncements

In November 2024, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) No. 2024-03, Income Statement - Reporting Comprehensive Income - Expense Disaggregation Disclosures (Subtopic 220-40) (“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 is effective for annual reporting periods beginning after December 15, 2026 and interim reporting periods beginning after December 15, 2027. ASU 2024-03 will be applied prospectively with the option for retrospective application. Early adoption is permitted. The Company is currently evaluating the impact of adopting this guidance.

In December 2023, the FASB issued ASU No. 2023-09, Income Taxes (Topic 740), Improvements to Income Tax Disclosures (“ASU 2023-09”). ASU 2023-09 requires entities to provide additional information of the Company’s tax rate reconciliation, as well as additional disclosures about income taxes paid by jurisdiction. ASU 2023-09 is effective for annual reporting periods beginning after December 15, 2024, with early adoption permitted. ASU 2023-09 should be applied prospectively, but entities have the option to apply it retrospectively for each period presented. The Company does not anticipate this guidance will have an adverse impact on its results of operations, cash flows, or financial condition, but it will result in expanded disclosure within the financial statements.

In November 2023, the FASB issued ASU No. 2023-07, Segment Reporting (Topic 280), Improvements to Reportable Segment Disclosures (“ASU 2023-07”). ASU 2023-07 requires incremental disclosures in annual and interim periods related to a public entity’s reportable segments (particularly on segment expenses) but does not change the definition of a segment, the method for determining segments, or the criteria for aggregating operating segments into reportable segments. The Company is in the process of evaluating the significant expenses of its single segment and determining the appropriate enhanced disclosures.

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.

Refinanced 2023 Term Loan Facility

On August 6, 2024, the Company ente red into Amendment No. 2 (the “Second Amendment”) to the revolving credit facility credit agreement dated June 21, 2023 (as amended, the “2023 Revolving Credit Agreement” and the credit facility thereunder, as amended, the “2023 Revolving Credit Facility”) among the Company, Allegro MicroSystems, LLC, (“AML”) Morgan Stanley Senior Funding, Inc., as the administrative agent and the collateral agent, and each lender from time to time party thereto. The Second Amendment increased the total capacity of the 2023 Revolving Credit Facility to $256,000.

The Second Amendment provided for a new $400,000 tranche of term loans maturing in 2030 (the “Refinanced 2023 Term Loan Facility”), the proceeds of which were primarily used to repurchase a portion of the Company’s common stock, pursuant to the certain Share Repurchase Agreement discussed in Note 14, repay the 2023 Term Loan Facility (as defined below), pay fees and expenses in connection with the foregoing and for general corporate purposes. The Refinanced 2023 Term Loan Facility amortizes at a rate of 1.00% per annum. The Refinanced 2023 Term Loan Facility bears interest, at the Company’s option, at a rate equal to (i) Term SOFR (as defined in the 2023 Revolving Credit Agreement) in effect from time to time plus 2.25% 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 1.25%. The Refinanced 2023 Term Loan Facility will mature on October 31, 2030. The Refinanced 2023 Term Loan Facility is subject to covenants consistent with the 2023 Revolving Credit Agreement covenants. As the terms of the refinancing were not substantially different from the terms of the Second Amendment, the refinancing was accounted for as a debt modification. In conjunction with the refinancing, the Company recognized $3,619 as a debt discount which will be amortized to interest expense over the remaining term using the effective interest method. Borrowings under the Second Amendment are collateralized by substantially all of the Company’s assets.

The Company was in compliance with its debt covenants as of December 27, 2024 and March 29, 2024.

A payment of $25,000 was applied to the term loan balance on October 31, 2024, which has eliminated future required minimum quarterly payments. The balance of the loan is required to be paid upon the expected maturity date of October 31, 2030.

2023 Term Loan Facility

On October 31, 2023, the Company entered into a $250,000 term loan maturing in 2030 (the “2023 Term Loan Facility”), the proceeds of which were used to refinance the $25,000 outstanding balance under the term loan credit agreement that the Company entered into on September 30, 2020 with Credit Suisse AG, Cayman Islands Branch, as administrative agent and collateral agent, and the other agents, arrangers and lenders party thereto, and to finance, in part, the acquisition of Crocus. The 2023 Term Loan Facility was executed as an incremental amendment (the “First Amendment”) to the 2023 Revolving Credit Agreement. The 2023 Term Loan Facility amortized at a rate of 0.25% per quarter, and the initial margin applicable to the 2023 Term Loan Facility was 2.75% for SOFR-based loans and 1.75% for base rate loans.

A payment of $50,000 was applied to the term loan balance on April 30, 2024. On August 6, 2024, the 2023 Term Loan Facility was paid in full in connection with the entry into the Second Amendment.

2023 Revolving Credit Facility

On June 21, 2023, the Company entered into the 2023 Revolving Credit Agreement with Morgan Stanley Senior Funding, Inc., as administrative agent, collateral agent, a letter of credit issuer and a lender, and the other agents, lenders and letter of credit issuers parties thereto. The 2023 Revolving Credit Agreement provided for the $224,000 2023 Revolving Credit Facility, which includes a $20,000 letter of credit subfacility. Upon entry into the Second Amendment with AML, Morgan Stanley Senior Funding, Inc., as the administrative agent and the collateral agent, and each lender from time to time party thereto, on August 6, 2024, the total capacity of

ALLEGRO MICROSYSTEMS, INC.

Notes to Unaudited Condensed Consolidated Financial Statements – (continued)

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

the 2023 Revolving Credit Facility was increased to $256,000. The 2023 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 2023 Revolving Credit Facility were not significant. As of December 27, 2024, there were no outstanding borrowings under the 2023 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 2023 Revolving Credit Facility exceed the outstanding loans and letters of credit under the 2023 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.

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, if estimable, will provide 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 condition.

13. Income Taxes

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

|  | Three-Month Period Ended |  |  | Nine-Month Period Ended |
|  | December 27, 2024 |  |  | December 29, 2023 |  |  | December 27, 2024 |  |  | December 29, 2023 |
Income tax (benefit) provision |  | $ | (803 | ) |  | $ | 2,969 |  |  | $ | (9,233 | ) |  | $ | 17,584 |
Effective tax rate |  |  | 10.6 | % |  |  | 8.2 | % |  |  | 13.7 | % |  |  | 9.9 | %

The Company’s income tax (benefit) provision is comprised of the 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, tax benefits generated by the foreign derived intangible income deduction including the permanent impacts of Internal Revenue Code Section 174 Capitalization, and research credits; offset by non-deductible stock-based compensation and other charges.

The increase in the effective tax rate for the three- and nine-month periods results mainly from a decrease in forecasted GAAP income before taxes, less tax deductions for share-based compensation, and an increase in nondeductible expenses primarily related to the Sanken Electric Co., Ltd. (“Sanken”) and Polar Semiconductor, LLC (“PSL”) transactions discussed in Note 14.

14. Related Party Transactions

Share repurchase transactions with Sanken

On July 23, 2024, the Company entered into a share repurchase agreement with Sanken (the “Share Repurchase Agreement”) pursuant to which the Company agreed to repurchase 38,767,315 shares of the Company’s common stock from Sanken in a privately negotiated transaction at a price per share equal to the price per share at which the underwriters in a public underwritten equity offering of shares of our common stock would purchase the shares (the “Equity Offering”). The repurchase of shares of common stock occurred in two separate closings, with the first closing taking place after the closing of the Equity Offering (the “First Closing”) and the second closing occurring after the receipt of the proceeds from borrowings under the Refinanced 2023 Term Loan Facility (the “Second Closing”). The First Closing of the share repurchase was conditioned upon the closing of the Equity Offering and certain other conditions, and the Second Closing of the share repurchase was conditioned upon the receipt of net proceeds of no less than $300,000 from incremental term loans under the Refinanced 2023 Term Loan Facility. Pursuant to the terms of the Share Repurchase Agreement, Sanken reimbursed the Company for the expenses incurred by the Company in connection with the transactions contemplated by the Share Repurchase Agreement, and paid a facilitation fee of $35,000, which were recorded within additional paid-in-capital within the condensed consolidated statements of changes in equity.

To fund the First Closing, the Company entered into an underwriting agreement (the “Underwriting Agreement”) with Barclays Capital Inc. and Morgan Stanley & Co. LLC, as representatives of the several underwriters (the “Underwriters”), on July 24, 2024, pursuant to which the Company agreed to sell 25,000,000 shares of the Company’s common stock, to the Underwriters at a price of $23.16 per share. Under the terms of the Underwriting Agreement, the Company granted the Underwriters a 30-day option to purchase up to an additional 3,750,000 shares of the Company’s common stock at the same purchase price, which option was exercised in full prior to the closing of the Equity Offering.

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

On July 26, 2024, the Company completed the Equity Offering pursuant to the Underwriting Agreement of 28,750,000 shares of its common stock at a public offering price of $24.00 per share resulting in net proceeds to the Company of approximately $665,850, after deducting $24,150 of underwriting discounts. As described above, the Company used the net proceeds of the Equity Offering to complete the First Closing under the Share Repurchase Agreement.

On July 29, 20 24, the Company completed the First Closing under the Share Repurchase Agreement, repurchasing 28,750,000 shares of the Company’s common stock f or aggregate consideration of $628,256, which was the Equity Offering price, less the facilitation fee of $35,000, underwriting discounts, and reimbursable transaction expenses. The shares repurchased in the First Closing were retired.

On August 7, 2024, the Company completed the Second Closing under the Share Repurchase Agreement, repurchasing 10,017,315 shares of the Company’s common stock for aggregate cash consideration of $225,549, which was the Equity Offering price, less underwriting discounts and reimbursable transaction expenses. As described above, the Company used a portion of the proceeds from the Refinanced 2023 Term Loan Facility and existing cash on hand to complete the Second Closing. The shares repurchased in the Second Closing were retired.

The Share Repurchase Agreement was accounted for as a forward repurchase contract as there were certain terms that could have caused the obligation not to be fulfilled. Accordingly, the contract was initially recorded as a liability at its fair value with subsequent remeasurements recognized in loss on change in fair value of forward repurchase contract until the completion of the First Closing and Second Closing. The Company recognized a loss of $34,752 as a result of the fair value forward repurchase contract in the condensed consolidated statements of operations.

In connection with the Share Repurchase Agreement, the Company entered into a Second Amended and Restated Stockholders Agreement with Sanken (the “Second Amended and Restated Stockholders Agreement”), which amended and restated the Amended and Restated Stockholders Agreement, dated as of June 16, 2022, by and among the Company, Sanken and OEP SKNA, L.P. (“OEP”). The Second Amended and Restated Stockholders Agreement, which became effective in accordance with its terms on July 29, 2024, removed OEP as a party and amended certain rights and obligations of the Company and Sanken.

Other transactions involving Sanken

Although certain costs were shared or allocated, cost of goods sold and gross margins attributable to related party sales were consistent with those of third-party customers. There were no trade accounts receivables, net, from Sanken as of December 27, 2024 or March 29, 2024. Other accounts receivable from Sanken totaled $119 and $160 as of December 27, 2024 and March 29, 2024, respectively. As of both December 27, 2024 and March 29, 2024, accounts payable to Sanken were not significant.

As of December 27, 2024, Sanken held approximately 32.5% of the Company’s outstanding common stock.

Transactions involving PSL

On April 25, 2024, the Company, Sanken, PSL and PS Investment Aggregator, L.P. (“Subscriber”) entered into a Sale and Subscription Agreement (the “PSL Agreement”), pursuant to which Subscriber and certain of its affiliates agreed to make capital contributions to PSL of $175,000 in exchange for an equity interest in PSL, which closed on September 20, 2024 (the “PSL Closing”). As contemplated by the PSL Agreement, the Company agreed to discharge all outstanding PSL Promissory Notes (as defined below) held by the Company for a value of $10,350 in exchange for PSL equity interests. Following the PSL Closing, the Company owned approximately 10.2% of PSL. As a result of PSL’s share issuance to Subscriber, the Company recognized a net loss of $2,804 primarily related to the difference between the selling price per share and its carrying amount per share and after a gain from the conversion of the PSL Promissory Notes. The loss is included in Other (expense) income, net in the condensed consolidated statements of operations.

At the PSL Closing, the Company, Sanken and Subscriber entered into an amended and restated limited partnership agreement (the “Limited Partnership Agreement”) with Polar Semiconductor GP I, LLC. The Limited Partnership Agreement contains representations, warranties and covenants of the parties customary for a transaction of this type, the reimbursement of expenses and costs, and restrictions on transfers.

The Company purchases in-process products from PSL. Purchases of various products from PSL totaled $11,533 and $40,867 for the three- and nine-month periods ended December 27, 2024, respectively, and $14,982 and $45,714 for the three- and nine-month periods ended December 29, 2023, respectively. Accounts payable to PSL included in amounts due to related party totaled $2,102 and $1,621 as of December 27, 2024 and March 29, 2024, respectively.

Our portfolio includes more than 1,000 products, and we ship over 1.5 billion units annually to more than 10,000 customers worldwide. During the three- and nine-month periods ended December 27, 2024, we generated $177.9 million and $532.2 million in total net sales, respectively, with $(6.8) million and $(58.0) million in net loss, respectively. During the three- and nine-month periods ended December 29, 2023, we generated $255.0 million and $808.8 million in total net sales, respectively, with $33.4 million and $160.0 million in net income, respectively.

Business Updates

During the nine-month period ended December 27, 2024, we entered into certain related party transactions with Sanken Electric Co., Ltd (“Sanken”). See Note 14, “Related Party Transactions” to the unaudited condensed consolidated financial statements included in this Quarterly Report for additional information.

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

Although inflation has moderated in recent periods, inflation rates in the markets in which we operate have increased and may continue to rise. 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 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 generally been able 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 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.

20

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 our significant original equipment manufacturer customers in most of 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 design mandates from our customers. Further, despite current inflationary conditions, we expect the average sales prices (“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 the 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 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. We are currently operating in an inflationary environment for our products.

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 declines often coincide with improvements in manufacturing yields and lower wafer, assembly, and testing costs, 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 as it did throughout fiscal year 2025, 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 capacity expansion are occasionally followed by significant market corrections in which sales decline, inventories accumulate, and facilities go underutilized. 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 and productivity and margins generally decline.

2017 Tax Cuts and Jobs Act

Pursuant to the 2017 Tax Cuts and Jobs Act, beginning in fiscal year 2023, U.S. tax law now requires us to capitalize and amortize domestic and foreign research and development expenditures over five and 15 years, for domestic and foreign research, respectively (“174 Capitalization”). The impact of 174 Capitalization for fiscal year 2025 is an increase in annual cash taxes of approximately $2.0 million and a foreign derived intangible income benefit of approximately $4.0 million. Additionally, the Internal Revenue Service has issued Notice 2024-12 and is expected to issue final guidance which may modify this law or change its impact.

Total net sales

Total net sales decreased in the three-month period ended December 27, 2024 compared to the three-month period ended December 29, 2023. The decrease was primarily driven by an overall reduction in customer-held inventory and resulting in a decline in shipments across all end markets. The decline in shipments impacted nearly all applications, including e-Mobility products, internal combustion engine, safety comfort and convenience applications, and other industrial applications, including clean energy and automation, data center applications, and smart home applications, partially offset by an increase in broad-based industrial applications.

Sales Trends by Market

The following table summarizes total net sales by market. The categorization of net sales by market is based on the characteristics of the end product and application into which our product will be designed.

|  | Three-Month Period Ended |  |  | Change |
|  | December 27, 2024 |  |  | December 29, 2023 |  |  | Amount |  |  | % |
|  | (Dollars in thousands) |
Automotive |  | $ | 130,066 |  |  | $ | 194,764 |  |  | $ | (64,698 | ) |  |  | (33.2 | )%
Industrial and other |  |  | 47,806 |  |  |  | 60,220 |  |  |  | (12,414 | ) |  |  | (20.6 | )%
Total net sales |  | $ | 177,872 |  |  | $ | 254,984 |  |  | $ | (77,112 | ) |  |  | (30.2 | )%

Automotive net sales decreased in the three-month period ended December 27, 2024 compared to the three-month period ended December 29, 2023, primarily due to inventory rebalancing with our automotive contract manufacturing customers looking to reduce inventory levels, as well as changes in product mix across all general applications.

Industrial and other net sales decreased in the three-month period ended December 27, 2024 compared to the three-month period ended December 29, 2023, primarily due to a decrease in demand for our data center applications, other industrial applications, and sales of smart home applications, partially offset by an increase in broad-based industrial applications.

Greater China net sales decreased in the three-month period ended December 27, 2024 compared to the three-month period ended December 29, 2023, primarily driven by reduced net sales of electric vehicles and advanced driver assistance systems applications, offset by an increase in broad-based applications. Americas net sales decreased due to the decline in demand in the United States automotive and industrial and other markets, primarily across all applications. Europe net sales declined in automotive markets, primarily driven by decline in electric vehicles. Other Asia net sales declined in data center applications, offset by an increase in broad-based industrial applications. South Korea net sales declined primarily in safety, comfort and convenience applications.

Cost of goods sold

Cost of goods sold decreased in the three-month period ended December 27, 2024 compared to the three-month period ended December 29, 2023, primarily due to a reduction in shipped volume, as well as a change in product mix, partially offset by an increase in amortization of intangible assets in relation to the acquisition of Crocus Technology International Corp. (“Crocus”).

Cost of goods sold as a percentage of our total net sales was 54.3% and 47.5% for the three-month periods ended December 27, 2024 and December 29, 2023, respectively. The increase was primarily due to the reduction in production volume, as well as a change in product mix noted above.

Gross profit and gross margin

Gross profit decreased in the three-month period ended December 27, 2024 compared to the three-month period ended December 29, 2023, primarily due to the decrease in net sales and a change in product mix noted above.

Gross margin was 45.7% and 52.5% for the three-month periods ended December 27, 2024 and December 29, 2023, respectively. The decrease was primarily due to the decline in net sales and a change in product mix noted above.

Research and development expenses

Research and development (“R&D”) expenses decreased in the three-month period ended December 27, 2024 compared to the comparable period in fiscal year 2024, primarily due to the reduction of R&D personnel costs, including the annual incentive program and a reduction in depreciation.

24

R&D expenses as a percentage of our total net sales was 24.4% and 17.4% for the three-month periods ended December 27, 2024 and December 29, 2023, respectively. The increase was primarily due to the decline in net sales, partially offset by the reduction from R&D personnel costs, including the annual incentive program.

Selling, general and administrative expenses

Selling, general and administrative (“SG&A”) expenses decreased in the three-month period ended December 27, 2024 compared to the three-month period ended December 29, 2023, primarily due to a decrease in outside service costs, personnel and severance expenses, and the annual incentive program.

SG&A expenses as a percentage of our total net sales was 21.3% and 20.7% in the three-month periods ended December 27, 2024 and December 29, 2023, respectively. The increase as a percentage of total net sales was primarily due to the decline in net sales, partially offset by a decrease in outside service costs, personnel and severance expenses, and the annual incentive program.

Interest expense

Interest expense increased in the three-month period ended December 27, 2024 compared to the three-month period ended December 29, 2023, due to higher interest payments on the Refinanced 2023 Term Loan Facility (as defined in Note 9, “Debt and Other Borrowings” to the unaudited condensed consolidated financial statements included in this Quarterly Report), which increased our total outstanding debt balance.

Interest income

Interest income decreased in the three-month period ended December 27, 2024 compared to the three-month period ended December 29, 2023, primarily due to lower cash and cash equivalent balances.

Other (expense) income, net

The foreign currency loss recorded in the three-month period ended December 27, 2024 was primarily due to realized and unrealized losses from our Philippine location. The foreign currency gain recorded in the three-month period ended December 29, 2023 was primarily due to realized and unrealized gains from our Philippine and France locations.

We recorded a gain of $0.7 million related to our investment in marketable securities and earnings in our money market fund deposits in the three-month period ended December 29, 2023.

Income tax (benefit) provision

Income tax benefit and the effective income tax rate were $(0.8) million and 10.6%, respectively, in the three-month period ended December 27, 2024, compared to income tax provision and effective income tax rate of $3.0 million and 8.2%, respectively, in the three-month period ended December 29, 2023. The increase in the effective tax rate (“ETR”) was mainly due to a decrease in forecasted GAAP income before taxes, less tax deductions for share-based compensation, and an increase in nondeductible expenses primarily related to the share repurchase transaction with Sanken (the “Sanken Transaction”) and PSL financing transaction (the “PSL Transaction” and the closing thereunder, the “PSL Closing”), each of which are described in more detail in Note 14, “Related Party Transactions” to the unaudited condensed consolidated financial statements included in this Quarterly Report.

(1) Our total net sales and cost of goods sold for the periods presented above include related party sales and cost of goods sold generated with Sanken. See our unaudited condensed consolidated financial statements included in this Quarterly Report for additional information regarding our related party net sales for the periods set forth above.

Total net sales

Total net sales decreased in the nine-month period ended December 27, 2024 compared to the nine-month period ended December 29, 2023. The decrease was primarily driven by an overall reduction in customer-held inventory resulting in a decline in shipments across all end markets. The decline in shipments impacted all applications including e-Mobility products, internal combustion engine, safety comfort and convenience applications, and broad-based and other industrial applications, including clean energy and automation, data center applications and consumer and smart home products.

Sales Trends by Market

The following table summarizes total net sales by market. The categorization of net sales by market is based on the characteristics of the end product and application into which our product will be designed.

|  | Nine-Month Period Ended |  |  | Change |
|  | December 27, 2024 |  |  | December 29, 2023 |  |  | Amount |  |  | % |
|  | (Dollars in thousands) |
Automotive |  | $ | 403,143 |  |  | $ | 577,515 |  |  | $ | (174,372 | ) |  |  | (30.2 | )%
Industrial and other |  |  | 129,039 |  |  |  | 231,271 |  |  |  | (102,232 | ) |  |  | (44.2 | )%
Total net sales |  | $ | 532,182 |  |  | $ | 808,786 |  |  | $ | (276,604 | ) |  |  | (34.2 | )%

Automotive net sales decreased in the nine-month period ended December 27, 2024 compared to the nine-month period ended December 29, 2023, primarily due to inventory rebalancing with our automotive contract manufacturing customers looking to reduce inventory levels, as well as changes in product mix across all general markets.

Industrial and other net sales decreased in the nine-month period ended December 27, 2024 compared to the nine-month period ended December 29, 2023, primarily due to a decrease in demand for our data center applications and our broad-based and other industrial applications, in addition to distributor inventory reductions.

Sales Trends by Product

The following table summarizes net sales by product.

|  | Nine-Month Period Ended |  |  | Change |
|  | December 27, 2024 |  |  | December 29, 2023 |  |  | Amount |  |  | % |
|  | (Dollars in thousands) |
MS |  | $ | 357,651 |  |  | $ | 503,635 |  |  | $ | (145,984 | ) |  |  | (29.0 | )%

Total net sales |  | $ | 532,182 |  |  | $ | 808,786 |  |  | $ | (276,604 | ) |  |  | (34.2 | )%

The decrease in MS and other sales was due to a decline in demand for our current and isolator products, as well as our magnetic speed and position sensors, partially offset by an increase in sales of our TMR solutions. The decline in PIC sales was primarily driven by a decrease in demand for our motor products and high performance power products.

Sales Trends by Geographic Location

Total net sales |  | $ | 532,182 |  |  | $ | 808,786 |  |  | $ | (276,604 | ) |  |  | (34.2 | )%

In Greater China, net sales decreased in the nine-month period ended December 27, 2024 compared to the nine-month period ended December 29, 2023, primarily due to the decline in automotive markets and industrial markets, offset by broad-based industrial applications, which are served through distributors currently managing inventory levels. Americas net sales decreased primarily due to the decline in the United States automotive and industrial markets across primarily all applications. In addition, Europe net sales declined in automotive and industrial, where demand in broad-based and other industrial applications has declined along with electric vehicles. South Korea net sales declined in the automotive applications, primarily safety, comfort and convenience applications, along with other declines in all auto applications. Other Asia net sales declined across industrial markets and auto markets in general, while Japan net sales declined in internal combustion engines, safety, comfort and convenience applications, advanced driver assistance systems and data center applications, partially offset by an increase in broad-based applications.

Cost of goods sold

Cost of goods sold decreased in the nine-month period ended December 27, 2024 compared to the nine-month period ended December 29, 2023, primarily due to a reduction in shipped volume as well as a change in product mix, partially offset by an increase in amortization of intangible assets in relation to the acquisition of Crocus.

Cost of goods sold as a percentage of our total net sales was 54.6% and 44.2% for the nine-month periods ended December 27, 2024 and December 29, 2023, respectively. The increase was primarily due to the reduction in production volume, as well as a change in product mix noted above.

Gross profit and gross margin

Gross profit decreased in the nine-month period ended December 27, 2024 compared to the nine-month period ended December 29, 2023, due to the decrease in net sales and a change in product mix noted above.

Gross margin was 45.4% and 55.8% for the nine-month periods ended December 27, 2024 and December 29, 2023, respectively. The decrease was primarily due to the decline in net sales and a change in product mix noted above.

27

Research and development expenses

R&D expenses increased in the nine-month period ended December 27, 2024 compared to the comparable period in fiscal year 2024, primarily due to an increase in R&D supplies, partially offset by a reduction from personnel costs, depreciation and R&D tax credits.

R&D expenses as a percentage of our total net sales was 24.8% and 16.2% for the nine-month periods ended December 27, 2024 and December 29, 2023, respectively. The increase was primarily due to the increase in R&D supplies in addition to the decline in net sales, partially offset by a reduction from personnel costs, depreciation and R&D tax credits noted above.

Selling, general and administrative expenses

SG&A expenses decreased in the nine-month period ended December 27, 2024 compared to the nine-month period ended December 29, 2023, primarily due to a decrease in the annual incentive program and outside service costs, partially offset by an increase in personnel and severance expenses.

SG&A expenses as a percentage of our total net sales was 21.8% and 17.3% in the nine-month periods ended December 27, 2024 and December 29, 2023, respectively. The increase as a percentage of total net sales was primarily due to the decline in net sales, partially offset by a decrease in outside service costs, personnel and severance expenses, and the annual incentive program.

Interest expense

Interest expense increased in the nine-month period ended December 27, 2024 compared to the nine-month period ended December 29, 2023, due to higher interest payments on the Refinanced 2023 Term Loan Facility, which increased our total outstanding debt balance.

Interest income

Interest income decreased in the nine-month period ended December 27, 2024 compared to the nine-month period ended December 29, 2023, primarily due to lower cash and cash equivalent balances.

Loss on change in fair value of forward repurchase contract

We recorded a loss on the change in fair value of a forward repurchase contract in the nine-month period ended December 27, 2024, primarily due to the various settlement dates under the Share Repurchase Agreement with Sanken as part of the Sanken Transaction.

Other (expense) income, net

The foreign currency loss recorded in the nine-month period ended December 27, 2024 was primarily due to realized and unrealized losses from our Philippine location. The foreign currency loss recorded in the nine-month period ended December 29, 2023 was related to our Philippines and United Kingdom locations, offset by gains in our France location.

We also recorded a net loss of $2.8 million as a result of the PSL Closing in the nine-month period ended December 27, 2024 related to the difference between the selling price per share and its carrying amount per share and after a gain from the conversion of PSL promissory notes that we held, partially offset by $1.2 million of gains related to earnings in our money market fund deposits. We recorded unrealized losses of $11.2 million related to our investment in marketable securities, partially offset by $11.3 million of gains related to sales of our investment in marketable securities and earnings in our money market fund deposits in the nine-month period ended December 29, 2023.

Income tax (benefit) provision

Income tax benefit and the effective income tax rate were $(9.2) million and 13.7%, respectively, in the nine-month period ended December 27, 2024, compared to income tax provision and effective income tax rate of $17.6 million and 9.9%, respectively, in the nine-month period ended December 29, 2023. The increase in the ETR was mainly due to a decrease in forecasted GAAP income before taxes, less tax deductions for share-based compensation, and an increase in nondeductible expenses primarily related to the Sanken Transaction and PSL Transaction.

Liquidity and Capital Resources

As of December 27, 2024, we had $138.5 million of cash and cash equivalents and $394.7 million of working capital, compared to $212.1 million of cash and cash equivalents and $454.3 million of working capital as of March 29, 2024. Working capital is impacted by the timing and extent of our business needs.

On August 6, 2024, we entered into Amendment No. 2 (the “Second Amendment”) to the revolving credit facility credit agreement dated June 21, 2023 (as amended, the “2023 Revolving Credit Agreement” and the credit facility thereunder, as amended, the “2023 Revolving Credit Facility”) among the Company, Allegro MicroSystems, LLC, Morgan Stanley Senior Funding, Inc., as the

28

administrative agent and the collateral agent, and each lender from time to time party there to. The Second Amendment increased the total capacity of the 2023 Revolving Credit Facility to $256 million and provided for a new $400 million tranche of term loans maturing in 2030 (the “Refinanced 2023 Term Loan Facility”), the proceeds of which were used, in relevant part to (i) repurchase a portion of our common stock, (ii) refinance our $250 million term loan maturing in 2030 (the “2023 Term Loan Facility”), (iii) pay fees and expenses in connection with the foregoing and (iv) for general corporate purposes. The Refinanced 2023 Term Loan Facility amortizes at a rate of 1.00% per annum. The Refinanced 2023 Term Loan Facility bears interest, at our option, at a rate equal to (i) Term SOFR in effect from time to time plus 2.25% 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 1.25%. The Refinanced 2023 Term Loan Facility will mature on October 31, 2030.

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 2025 is to utilize cash on hand and capacity under our 2023 Revolving Credit Facility to support our continued growth initiatives into select markets and planned capital expenditures, as well as consider potential acquisitions. As of December 27, 2024, 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 upcoming 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, 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 16, “Commitments and Contingencies” and Note 15, “Retirement Plans” to the audited consolidated financial statements in the Company’s 2024 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 2023 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 nine-month periods ended December 27, 2024 and December 29, 2023:

|  | Nine-Month Period Ended |
|  | December 27, 2024 |  |  | December 29, 2023 |

Effect of exchange rate changes on cash and cash equivalents and restricted cash |  |  | (1,305 | ) |  |  | 375 |
Net decrease in cash and cash equivalents and restricted cash |  | $ | (73,199 | ) |  | $ | (134,970 | )

Operating Activities

Net cash provided by operating activities was $41.6 million in the nine-month period ended December 27, 2024, resulting primarily from a net loss of $58.0 million and noncash charges of $120.0 million, further adjusted by a net decrease in cash from an increase in net operating assets and liabilities of $20.4 million. Noncash charges primarily included increases of $48.6 million for depreciation and amortization, $34.8 million for loss on change in fair value of forward repurchase contract, $32.3 million of stock-based compensation, $7.5 million for provisions for inventory and expected credit losses and $6.6 million of other non-cash reconciling items, partially offset by $11.5 million of deferred income taxes. The net increase in operating assets and liabilities consisted of a $38.1 million increase in inventories, a $21.3 million decrease in accrued expenses and other current and long-term liabilities, partially offset by $34.4 million decrease in trade accounts receivable, net, a $5.5 million increase in trade accounts payable and a $0.6 million increase in net amounts due to related party. The decrease in trade accounts receivable, net was primarily a result of decreased sales year-over-year. Trade accounts payable increased primarily due to the timing of payments to suppliers and vendors, including unpaid capital expenditures of $1.7 million. The increase in net amounts due to related parties was primarily due to variations in the timing of such

payments in the ordinary course of business. The increase in inventories was primarily the result of inventory builds of standard products to support anticipated sales growth. The increase in prepaid expenses and other assets was mostly due to higher long-term deposits and the timing of tax payments. The decrease in accrued expenses and other current and long-term liabilities was primarily the result of a reduction in accrued personnel costs due to the timing of payments pursuant to our annual incentive compensation plan.

The increase in inventories was primarily the result of inventory builds to support anticipated sales growth for the remainder of fiscal year 2024. The decrease in accrued expenses and other current and long-term liabilities was primarily the result of a reduction in accrued personnel costs due to timing of payments pursuant to our annual incentive compensation plan. The increase in prepaid expenses and other assets was mostly due to higher long-term deposits and the timing of tax payments.

Our significant accounting policies are described in Note 2, “Summary of Significant Accounting Policies” to our consolidated financial statements included in our 2024 Annual Report.

Item 4. Controls a nd Procedures.

Limitations on Effectiveness of Controls and Procedures

In designing and evaluating our disclosure controls and procedures (as defined in Rules 13a-15(e) and 15d-15(e) under the Securities Exchange Act of 1934, as amended (the “Exchange Act”)), management recognizes that any controls and procedures, no matter how well designed and operated, can provide only reasonable assurance of achieving the desired control objectives. In addition, the design of disclosure controls and procedures must reflect the fact that there are resource constraints and that management is required to apply judgment in evaluating the benefits of possible controls and procedures relative to their costs.

Evaluation of Disclosure Controls and Procedures

Our management, with the participation of our Chief Executive Officer and Chief Financial Officer (our principal executive officer and principal financial officer, respectively), evaluated the effectiveness of our disclosure controls and procedures as of December 27, 2024. Based on the evaluation of our disclosure controls and procedures as of December 27, 2024, our Chief Executive Officer and Chief Financial Officer concluded that, as of such date, our disclosure controls and procedures were effective at the reasonable assurance level.

Changes in Internal Control over Financial Reporting

There were no changes in our internal control over financial reporting (as defined in Rules 13a-15(f) and 15(d)-15(f) under the Exchange Act) that occurred during the period covered by this Quarterly Report that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.
