– Full Year 2024 Sales Increase 8% to a Record $1.05 Billion

–38% Growth in E-Mobility Drives 17% Year-over-Year Increase in Full Year 2024 Automotive Sales –

Manchester, NH, May 9, 2024 – Allegro MicroSystems, Inc. (“Allegro” or the “Company”) (Nasdaq:ALGM), a global leader in power and sensing semiconductor solutions for motion control and energy efficient systems, today announced financial results for its fourth quarter and full year ended March 29, 2024.

“Continued strong momentum in e-Mobility drove record fiscal year 2024 sales to more than $1 billion and record non-GAAP earnings per share of $1.35. We also achieved a record level of design wins of more than $1 billion. I would like to thank the entire Allegro team for their contributions which enabled us to achieve these significant milestones,” said Vineet Nargolwala, President and CEO of Allegro. "During fiscal year 2024, we strengthened our market-leading positions in magnetic sensing and power solutions with the addition of highly differentiated TMR technology to our portfolio and introduction of high voltage isolated gate drivers to the market, enabling us to continue to deliver innovative, high-value solutions to our customers. As we look ahead into fiscal year 2025, our first quarter guide comprehends working closely with customers to manage orders to reduce inventory in the channel and return to normalized business levels. We continue to expect a return to sequential growth in the second quarter. Our design wins and continued momentum with customers gives us confidence in the mid and longer-term growth trajectory.”

Fourth Quarter and Full Fiscal Year 2024 Financial Highlights:

*During the preparation of the third quarter fiscal year 2024 interim condensed consolidated financial statements, the Company identified an immaterial error in the classification of net sales by application with the table above, whereby customer returns and sales allowances were incorrectly classified by application between Automotive, Industrial and Other in the prior periods presented above. There was no impact to previously reported total net sales or net income in any of the periods noted above.

Business Outlook

For the first quarter of fiscal year 2025 ending June 28, 2024, the Company expects net sales to be in the range of $160 million to $170 million. The Company also estimates the following results on a non-GAAP basis:

The Company also made a $50 million voluntary payment on its term loan, which is expected to reduce annualized interest expense by approximately $4 million dollars.

Allegro has not provided a reconciliation of its first fiscal quarter outlook for non-GAAP Gross Margin, non-GAAP Operating Expenses, and non-GAAP Diluted Earnings per Share because estimates of all of the reconciling items cannot be provided without unreasonable efforts. It is difficult to reasonably provide a forward-looking estimate between such forward-looking non-GAAP measures and the comparable forward-looking U.S. generally accepted accounting principles (“GAAP”) measures. Certain factors that are materially significant to Allegro’s ability to estimate these items are out of its control and/or cannot be reasonably predicted.

Earnings Webcast

A webcast will be held on Thursday, May 9, 2024 at 8:30 a.m., Eastern Time. Vineet Nargolwala, President and Chief Executive Officer, will discuss Allegro’s business and financial results.

The webcast will be available on the Investor Relations section of the Company’s website at investors.allegromicro.com. A recording of the webcast will be posted in the same location shortly after the call concludes and will be available for at least 90 days.

Non-GAAP Financial Measures

In addition to the measures presented in our consolidated financial statements, we regularly review other measures, defined as non-GAAP financial measures by the SEC, to evaluate our business, measure our performance, identify trends, prepare financial forecasts and make strategic decisions. The key measures we consider are non-GAAP Gross Profit, non-GAAP Gross Margin, non-GAAP Operating Expenses, non-GAAP Operating Income, non-GAAP Operating Margin, EBITDA, Adjusted EBITDA, Adjusted EBITDA margin, non-GAAP Profit before Tax, non-GAAP Income Tax Provision, non-GAAP Net Income, non-GAAP Basic and Diluted Earnings per Share, and non-GAAP Free Cash Flow (collectively, the “Non-GAAP Financial Measures”). These Non-GAAP Financial Measures provide supplemental information regarding our operating performance on a non-GAAP basis that excludes certain gains, losses and charges of a non-cash nature or that occur relatively infrequently and/or that management considers to be unrelated to our core operations, and in the case of non-GAAP Income Tax Provision, management believes that this non-GAAP measure of income taxes provides it with the ability to evaluate the non-GAAP Income Tax Provision across different reporting periods on a consistent basis, independent of special items and discrete items, which may vary in size and frequency. These Non-GAAP Financial Measures are used by both management and our board of directors, together with the comparable GAAP information, in evaluating our current performance and planning our future business activities.

The Non-GAAP Financial Measures are supplemental measures of our performance that are neither required by, nor presented in accordance with, GAAP. These Non-GAAP Financial Measures should not be considered as substitutes for GAAP financial measures such as gross profit, gross margin, net income or any other performance measures derived in accordance with GAAP. Also, in the future we may incur expenses or charges such as those being adjusted in the calculation of these Non-GAAP Financial Measures. Our presentation of these Non-GAAP Financial Measures should not be construed as an inference that future results will be unaffected by unusual or nonrecurring items. These Non-GAAP Financial Measures exclude costs related to acquisition and related integration expenses, amortization of acquired intangible assets, stock-based compensation, restructuring actions, related party activities and other non-operational costs.

Non-GAAP Income Tax Provision

In calculating non-GAAP Income Tax Provision, we have added back the following to GAAP Income Tax Provision:
