Exhibit 99.1

Allegro MicroSystems Reports First Quarter Results Including Recent Records In Revenue and Profit

--ADAS and xEV Demand Acceleration and Design Win Momentum Support Strong Growth and Margin Expansion--

Manchester, NH, July 29, 2021 – 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 first fiscal quarter for fiscal year 2022 that ended June 25, 2021. The Company delivered net sales of $188.1 million in the quarter, a sequential increase of 7%. Strong gross margins and solid execution enabled significant earnings per share growth on both a GAAP and non-GAAP basis to $0.14 and $0.18, respectively. The Company also achieved design win acceleration in key markets during the quarter, which it expects will provide increasing momentum for long-term growth potential.

Quarter Highlights:

•Total net sales of $188.1 million were up 7% sequentially and 64% year over year.

•Automotive net sales increased 13% sequentially in fiscal Q1 to a record $133.5 million, up 75% year-over year.

•Industrial net sales of $30.3 million was also a record for the business.

•GAAP gross margin of 50.0% and non-GAAP gross margin of 52.2% represented recent records and strong progress towards the Company’s target model.

•GAAP operating income for the quarter increased meaningfully to $32.2 million, or 17.1% of net sales. Non-GAAP operating income increased 21.7% sequentially to $41.9 million, or 22.3% of net sales.

•GAAP diluted EPS increased by $0.09 sequentially to $0.14 in Q1 and non-GAAP diluted EPS increased by 20.0% sequentially to $0.18, exceeding prior expectations.

“Record revenue in the first fiscal quarter was anchored on strength across our strategic product lines and end markets. Our Automotive and Industrial businesses both reached record revenue levels demonstrating strength across our increasingly diversified business. We achieved record revenue for both Magnetic Sensors and Power ICs, reflecting increased content in our target applications. Our gross margins continued to expand meaningfully this quarter, and our backlog is at historic highs,” said Ravi Vig, President and CEO of Allegro MicroSystems. “Looking ahead, I am very enthusiastic about the prospects for the business. We believe the recovery is still in its early stages and even more importantly, that the underlying diversity of our business, the resilience of our operating model, our continued design win momentum and alignment to multiple growth vectors support the potential to outperform long-term.”

Business Summary

Automotive represented 71% of revenue and increased 13% sequentially to a record $133.5 million, up 75% year-over year. Revenue increased sequentially across all of the Company’s automotive end markets, with both ADAS and xEV revenue up nearly 80% year over year. Design win momentum is significantly outpacing the Company’s targets as a result of the transformative shift underway in the automotive business to high growth xEV and ADAS applications.

Industrial represented 16% of net sales and increased 4% sequentially and 49% year over year. Growth areas reflected the increasing diversification of the Company’s served industrial end markets, with broad-based revenue delivering double digit growth.

Business Outlook

Given the strength of the backlog and extended order coverage, for the second quarter ending September 24, 2021, the Company expects total net sales to be in the range of $185 million to $191 million. Non-GAAP gross margin is expected to be about flat and non-GAAP earnings per fully-diluted share for the same period is expected to be in the range of $0.18.

Allegro has not provided a reconciliation of its second fiscal quarter outlook for non-GAAP gross margin and non-GAAP earnings per fully-diluted 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 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, July 29, 2021 at 8:00 a.m. Eastern time. Ravi Vig, President and Chief Executive Officer and Paul Walsh, Chief Financial Officer, will discuss Allegro’s 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 30 days.

Non-GAAP Financial Measures

In addition to the measures presented in our consolidated financial statements, we regularly review other metrics, 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 metrics we consider are non-GAAP Gross Profit, non-GAAP Gross Margin, non-GAAP Operating Expenses, non-GAAP Operating Income, non-GAAP Operating Margin, non-GAAP Profit

before Tax, non-GAAP Provision for Income Tax, non-GAAP Net Income, non-GAAP Net Income per Share, EBITDA, Adjusted EBITDA and Adjusted EBITDA margin (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 Provision for Income Tax, management believes that this non-GAAP measure of income taxes provides it with the ability to evaluate the non-GAAP Provision for Income Taxes across different reporting periods on a consistent basis, independent of special items and discrete items, which may vary in size and frequency. By presenting these Non-GAAP Financial Measures, we provide a basis for comparison of our business operations between periods by excluding items that we do not believe are indicative of our core operating performance, and we believe that investors’ understanding of our performance is enhanced by our presenting these Non-GAAP Financial Measures, as they provide a reasonable basis for comparing our ongoing results of operations. Management believes that tracking and presenting these non-GAAP Financial Measures provides management and the investment community with valuable insight into matters such as: our ongoing core operations, our ability to generate cash to service our debt and fund our operations; and the underlying business trends that are affecting our performance. 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. In particular, management finds it useful to exclude non-cash charges in order to better correlate our operating activities with our ability to generate cash from operations and to exclude certain cash charges as a means of more accurately predicting our liquidity requirements. We believe that these Non-GAAP Financial Measures, when used in conjunction with our GAAP financial information, also allow investors to better evaluate our financial performance in comparison to other periods and to other companies in our industry.

These Non-GAAP Financial Measures have significant limitations as analytical tools. Some of these limitations are that:

•such measures do not reflect our cash expenditures, or future requirements for capital expenditures or contractual commitments;

•such measures exclude certain costs which are important in analyzing our GAAP results;

•such measures do not reflect changes in, or cash requirements for, our working capital needs;

•such measures do not reflect the interest expense, or the cash requirements necessary to service interest or principal payments on our debt;

•such measures do not reflect our tax expense or the cash requirements to pay our taxes;

•although depreciation and amortization are non-cash charges, the assets being depreciated and amortized will often have to be replaced in the future;

•such measures do not reflect any cash requirements for such replacements; and

•other companies in our industry may calculate such measures differently than we do, thereby further limiting their usefulness as comparative measures.

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 added back 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.

Our prior disclosure referred to non-GAAP Gross Profit and non-GAAP Gross Margin as Adjusted Gross Profit and Adjusted Gross Margin, respectively. No changes have been made to how we calculate these measures.

Non-GAAP Gross Profit and Non-GAAP Gross Margin

We calculate non-GAAP Gross Profit and non-GAAP Gross Margin excluding the items below from cost of goods sold in applicable periods, and we calculate non-GAAP Gross Margin as non-GAAP Gross Profit divided by total net sales.

•One-time other expenses—Represents costs related to the discontinuation of one of our product lines manufactured by Voxtel.

•PSL and Sanken Distribution Agreement—Represents the elimination of inventory cost amortization and foundry service payment related to one-time costs incurred in connection with the disposition of Polar Semiconductor, LLC (“PSL”) during the fiscal year ended March 26, 2021 (the “PSL Divestiture”).

•Stock-based compensation—Represents non-cash expenses arising from the grant of stock-based awards.

•AMTC Facility consolidation one-time costs—Represents one-time costs incurred in connection with closing of our manufacturing facility in Thailand (the “AMTC Facility”) and transitioning of test and assembly functions to our manufacturing facility in the Philippines (the “AMPI Facility”) announced in fiscal year 2020, consisting of: moving equipment between facilities, contract terminations and other non-recurring charges. The closure and transition of the AMTC Facility was substantially completed in March 2021. These costs are in addition to, and not duplicative of, the adjustments noted in note (*) below.

•Amortization of acquisition-related intangible assets—Represents non-cash expenses associated with the amortization of intangible assets in connection with the acquisition of Voxtel, which closed in August 2020.

•COVID-19 related expenses—Represents expenses attributable to the COVID-19 pandemic primarily related to increased purchases of masks, gloves and other protective materials, and overtime premium compensation paid for maintaining 24-hour service at the AMPI Facility.

(*) Non-GAAP Gross Profit and the corresponding calculation of non-GAAP Gross Margin do not include adjustments consisting of:

•Additional AMTC-related costs—Represents costs relating to the closing of the AMTC Facility and the transitioning of test and assembly functions to the AMPI Facility in the Philippines announced in fiscal year 2020 consisting of the net savings expected to result from the movement of work to the AMPI Facility, which facility had duplicative capacity based on the buildouts of the AMPI Facility in fiscal years 2019 and 2018. The elimination of these costs did not reduce our production capacity and therefore did not have direct effects on our ability to generate revenue. The closure and transition of the AMTC Facility was substantially completed in March 2021.

Non-GAAP Operating Expenses, non-GAAP Operating Income and non-GAAP Operating Margin

We calculate non-GAAP Operating Expenses and non-GAAP Operating Income excluding the same items excluded above to the extent they are classified as operating expenses, and also excluding the items below in applicable periods. We calculate non-GAAP Operating Margin as non-GAAP Operating Income divided by total net sales.

•Transaction fees—Represents transaction-related legal and consulting fees incurred primarily in connection with (i) the acquisition of Voxtel in fiscal year 2020, and (ii) one-time transaction-related legal and consulting fees in fiscal 2021.

•Severance—Represents severance costs associated with (i) labor savings initiatives to manage overall compensation expense as a result of the declining sales volume during the applicable period, including a voluntary separation incentive payment plan for employees near retirement and a reduction in force, (ii) the closing of the AMTC Facility and the transitioning of test and assembly functions to the AMPI Facility announced and initiated in fiscal year 2020, and (iii) costs related to the discontinuation of one of our product lines manufactured by Voxtel in fiscal year 2022.

•Impairment of long-lived assets—Represents impairment charge incurred in connection with the planned sale of the AMTC Facility.

•Change in fair value of contingent consideration—Represents the change in fair value of contingent consideration payable in connection with the acquisition of Voxtel.

•Income in earnings of equity investment—Represents our equity method investment in PSL.

Non-GAAP Profit before Tax, Non-GAAP Net Income, and Non-GAAP Basic and Diluted Earnings Per Share

We calculate non-GAAP Profit before Tax as Income before Tax Provision excluding the same items excluded above and also excluding the item below in applicable periods. We calculate non-GAAP Net Income as Net Income excluding the same items excluded above and also excluding the item below in applicable periods.

Non-GAAP Provision for Income Tax
