Allegro MicroSystems Reports Second Quarter 2027 Results

Second Quarter Sales Increased by 29% Year-over-Year to $277 Million

Record Industrial & Other and Data Center Sales

GAAP EPS Quadrupled and Non-GAAP EPS Doubled Year-over-Year

Manchester, NH, October 29, 2026 – 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 ended September 25, 2026.

“We saw continued strong momentum in our fiscal second quarter, delivering our seventh consecutive quarter of sequential sales growth. Sales were $277 million, representing a 29% increase year-over-year. GAAP earnings per share quadrupled from $0.03 per share in the fiscal second quarter of 2026 to $0.12. Non-GAAP EPS grew to $0.26, doubling over the second quarter of fiscal 2026. Broad year-over-year sales growth in Automotive and Industrial end markets drove this strong performance, led by data center, which established a new record,” said Mike Doogue, President and CEO of Allegro. “Our forward demand signals strengthened significantly this quarter. We delivered our highest quarterly design-win performance since our 2020 IPO—up nearly 40% year-over-year—and bookings increased for the eighth consecutive quarter. With record design wins, a robust backlog, and expanding content across our target Automotive and Industrial markets, the leading indicators across our business give us high confidence in our path to exceed our target model of mid-teens annual sales growth.”

“During the quarter, we also continued to execute on our strategic priorities of expanding profitability and generating strong cash flow,” said Derek D’Antilio, Executive Vice President and CFO of Allegro. “On September 30, 2026, following the close of the second quarter, we made another $25 million voluntary debt repayment, underscoring the strength of our balance sheet and our confidence in Allegro’s anticipated free cash flow generation.”

Business Outlook

For the third quarter of fiscal year 2027 ending December 25, 2026, the Company expects total net sales to be in the range of $278 million to $288 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 51.5% and 52.5%,

• Operating expenses are expected to be $87 million, plus or minus $1 million, and

• Diluted Earnings per Share is expected to be between $0.25 and $0.29, with the mid-point of this range implying an 80% year-over-year increase.

Allegro has not provided a reconciliation of its third 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.
