Exhibit 99.1
CORRECTION - Allegro MicroSystems Reports Second Quarter of Fiscal Year 2022 Results
--Company Achieves Record Quarterly Revenue and Profitability--
Manchester, NH, October 28, 2021 – In a release issued under the same headline earlier today by Allegro MicroSystems, Inc. (Nasdaq:ALGM), please note that the line item for Unrealized gains on marketable securities was not displayed in the Cash Flows from Operating Activities table, while the totaled line item for Net cash provided by operating activities was and is correct. The corrected release follows:

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 second quarter of fiscal year 2022 that ended September 24, 2021. The Company’s net sales increased 3% sequentially and 42% over the same period of the prior year to a new quarterly record of $193.6 million. The Company’s successful execution of its strategic manufacturing and product portfolio transformation supported strong gross margins and significant earnings per share growth.
Quarter Highlights:
Total net sales of $193.6 million exceeded expectations due to strength in industrial and other end markets.
Automotive net sales of $126.0 million were up 41% year-over-year.
Record Industrial net sales of $36.3 million were up 68% year-over-year.
The Company continues to see record backlog and low inventory across the supply chain.
GAAP gross margin of 53.0% and non-GAAP gross margin of 53.8% contributed to record high profitability.
GAAP operating income for the quarter increased to $38.6 million, or 19.9% of net sales. Non-GAAP operating income increased to $46.6 million, or 24.1% of net sales, rising 11% sequentially.
Earnings per share exceeded expectations, with GAAP diluted EPS increasing to $0.17 in Q2 and non-GAAP diluted EPS increasing by 11% sequentially to $0.20.

“Our strong Q2 performance highlights two key differentiators in the Allegro business model - our diversification into high growth markets and our structural transformation to achieve improved gross margins,” said Ravi Vig, President and CEO of Allegro MicroSystems. “We are pleased with the progress in both our top line and our gross margin expansion. Despite temporary COVID-related supply chain disruptions affecting fiscal Q3, supply recovery is already underway giving us confidence in a return to growth in Q4 and confidence in revenue growth of about 28% in fiscal 2022. Based on strong end market positioning, business fundamentals, and design win momentum, we believe we are well positioned to deliver low to mid-teens revenue growth and strong gross margins for fiscal 2023.”
Business Summary and Outlook
Automotive represented 65% of revenue and declined 6% sequentially. Revenue was up 41% year-over year, led by the Company’s strategic focus areas of ADAS and xEV which continue to steadily increase as a percent of automotive revenue.

Industrial end markets represented 19% of revenue and increased 20% sequentially and 68% year over year, reaching a new quarterly high. Revenue increased sequentially across all of the Company’s industrial end markets, including green energy and data center, showcasing the diverse nature of the business.

For the third quarter ending December 24, 2021, the Company expects total net sales to be in the range of $180 million to $185 million. The anticipated sequential decline reflects the impact of COVID-related shutdowns of third-party factories in Malaysia that occurred recently. These factories are back online and, given continued strong demand and record levels of backlog, the Company expects a return to sequential growth in the fourth quarter. Based on accelerating design win momentum, the Company now has confidence in revenue growth in the low to mid-teens for fiscal 2023. Non-GAAP gross



margin for the third quarter is expected to remain about flat to the new higher levels, and non-GAAP earnings per diluted share for the same period are expected to be in the range of $0.18.
Allegro has not provided a reconciliation of its third fiscal quarter outlook for non-GAAP gross margin and non-GAAP earnings per 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, October 28, 2021 at 8:30 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.

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.
Voxtel inventory impairment—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 and closed on the sale in August 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 and closed on the sale in August 2021.
Out of period adjustment for depreciation expense of giant magnetoresistance assets (“GMR assets”)—Represents a one-time depreciation expense related to the correction of an immaterial error, related to 2017, for certain manufacturing assets that have reached the end of their useful lives.

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.



Change in fair value of contingent consideration—Represents the change in fair value of contingent consideration payable in connection with the acquisition of Voxtel.
(**) Non-GAAP Operating Income does not include adjustments consisting of those set forth in note (*) to the calculation of non-GAAP Gross Profit, and the corresponding calculation of non-GAAP Gross Margin, above or:
Labor savings—Represents salary and benefit costs related to employees whose positions were eliminated through voluntary separation programs or other reductions in force (not associated with the closure of the AMTC Facility or any other plant or facility) and a restructuring of overhead positions from high-cost to low-cost jurisdictions net of costs for newly hired employees in connection with such restructuring.
EBITDA, Adjusted EBITDA, and Adjusted EBITDA Margin
We calculate EBITDA as net income minus interest income (expense), tax provision (benefit), and depreciation and amortization expenses. We calculate Adjusted EBITDA as EBITDA excluding the same items excluded above and also excluding the items below in applicable periods. We calculate Adjusted EBITDA Margin as Adjusted EBITDA divided by total net sales.
Non-core (gain) loss on sale of equipment—Represents non-core miscellaneous losses and gains on the sale of equipment.
Foreign currency translation (gain) loss—Represents losses and gains resulting from the remeasurement and settlement of intercompany debt and operational transactions, as well as transactions with external customers or vendors denominated in currencies other than the functional currency of the legal entity in which the transaction is recorded.
Income in earnings of equity investment—Represents our equity method investment in PSL.
Unrealized gains on investments—Represents mark-to-market adjustments on equity investments with readily determinable fair values.
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
In calculating non-GAAP Provision for Income Tax, we have added back the following to GAAP Income Tax Provision:
Tax effect of adjustments to GAAP results—Represents the estimated income tax effect of the adjustments to non-GAAP Profit Before Tax described above and elimination of discrete tax adjustments.
