MANCHESTER, N.H., May 07, 2026 (GLOBE NEWSWIRE) -- 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 fiscal year ended March 27, 2026.

For the full year, sales grew 23% to $890 million and non-GAAP EPS more than doubled to $0.54. These results reflect strength in Focus Auto sales - including xEV and ADAS – and Data Center, which reached a record 14% of total Q4 sales,” said Mike Doogue, President and CEO of Allegro MicroSystems. “As we enter fiscal 2027, we see demand trends that support continued growth, and remain confident in our ability to execute towards our target financial model.”

For the first quarter of fiscal year 2027 ending June 26, 2026, the Company expects total net sales to be in the range of
$245 million to $255 million. At the midpoint of this range, it implies growth in net sales of 23% year-over-year.
The Company also estimates the following results on a non-GAAP basis:
Gross Margin is expected to be between 50% and 51%,Operating expenses are expected to be $80 million, plus or minus $2 million, andDiluted Earnings per Share is expected to be between $0.19 and $0.23.
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.

These non-GAAP financial measures are provided in addition to, and not as a substitute for or superior to measures of, financial performance prepared in accordance with GAAP. There are a number of limitations related to the use of these non-GAAP financial measures versus their most directly comparable GAAP equivalents. For example, other companies may calculate non-GAAP financial measures differently or may use other measures to evaluate their performance, all of which could reduce the usefulness of the presented non-GAAP financial measures as tools for comparison.

In addition to the measures presented in our condensed 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 (Benefit), non-GAAP Effective Tax Rate, non-GAAP Net Income Attributable to Allegro MicroSystems, Inc, non-GAAP Basic and Diluted Earnings per Share, non-GAAP Free Cash Flow, and non-GAAP Free Cash Flow as a percentage of net sales (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 (Benefit), management believes that this non-GAAP measure of income taxes provides it with the ability to evaluate the non-GAAP Income Tax Provision (Benefit) 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 (Benefit)
In calculating the non-GAAP Income Tax Provision (Benefit), we adjust for the tax effect of adjustments to GAAP results which represents the estimated income tax effect of the adjustments to non-GAAP Profit before Tax described below. We also adjust for any discrete tax items and the impact of non-recurring tax law changes to ensure the non-GAAP Income Tax Rate (“NG ETR”) reflects future operations.
Our fiscal year 2026 and 2027 NG ETR excludes the impact of the 2025 One Big Beautiful Bill Act’s one-time research and development amortization election which accelerates the amortization of previously capitalized domestic research and development over a two-year period. The NG ETR is applied to non-GAAP Profit before Tax to arrive at the tax effect of adjustments to GAAP results.
