Properties, in its own words

Manufacturing, Operations and Facilities

Our corporate headquarters is located in Manchester, New Hampshire, and we have a global footprint with 27 locations across four continents. As of the end of fiscal year 2026, our operations are primarily conducted at the locations shown below. Our AMPI subsidiary in Manila, Philippines operates as our primary internal assembly and testing facility.

The rest of Item 2

Facility · Facility Function · Facility Size · Status

Manila, Philippines · Manufacturing - Assembly, Test, Finish · Approximately 440,000 square feet · Owned

Muntinlupa City, Philippines · Research and Development, Administrative · Approximately 40,000 square feet · Leased (Five-year lease expires in 2028)

Manchester, New Hampshire · Corporate Headquarters, Research and Development, Administrative · Approximately 125,000 square feet · Owned

We also lease design and applications support centers in the Americas, Asia and Europe. Our decision to open and maintain additional design centers is based on several factors, including the ability to employ talented engineers at efficient costs and to better serve our local customer base.

Our manufacturing strategy consists of a combined internal and external sourcing strategy. This approach enhances security of supply by providing capacity throughout the manufacturing process and has enabled us to reduce capital requirements and reduce fixed costs, access additional capacity during periods of high demand and establish wafer process technology collaborations.

We have a fabless business model that provides us with enhanced security of supply and manufacturing flexibility. Our primary fab partners currently include UMC, PSL, Tower and TSMC. We have master service agreements with all primary foundry partners, and we have also engaged in long-term supply agreements with some of our foundry partners.

AMPI is our primary internal assembly and testing facility for our sensor and power products, with packaging capabilities and quality standards that meet stringent automotive safety and reliability specification requirements. We also supplement AMPI’s assembly capabilities with subcontractors throughout Asia, and approximately 51%, 45% and 47% of our assembly was outsourced in fiscal years 2026, 2025 and 2024, respectively. We continue to make progress expanding our regional manufacturing capabilities in Asia. During fiscal year 2026, we began shipping to regional customers from additional OSAT partners in Asia.

While our principal test operations are performed at AMPI, additional test capabilities are available at our Manchester, New Hampshire facility, and a small portion of testing is outsourced, including the addition of OSAT partners in Asia as part of our regional manufacturing strategy.

We are committed to manufacturing products of the highest quality and performance. We strive to have a “zero-defect” quality culture focused on meeting or exceeding demanding high-temperature automotive quality standards. We strive to comply with industry standards such as IATF 16949:2016 (the automotive sector-specific quality management system standard) and ISO 14001 (a voluntary standard for environmental management published by the International Standards Organization), and we also strive to comply with ISO 26262 ASIL product development standards, RoHS and similar environmental product requirements. Leading global automotive, industrial, and consumer manufacturers regularly audit our facilities for compliance with these standards, as well as with their own customer-specific standards.

Risk factors and legal proceedings

The risks Allegro MicroSystems names in Item 1A of its 10-K filed May 21, 2026: 41 risks under these headings, as written.8

  • Risks Related to Our Business and Industry
  • Downturns or volatility in general economic conditions could have a material adverse effect on our business, financial condition, results of operations and liquidity.
  • We face intense competition and may not be able to compete effectively, which could reduce our market share and decrease our net sales and profitability.
  • We rely on a limited number of third-party semiconductor wafer fabrication facilities and a limited number of suppliers of other materials, and the failure of any of these suppliers to supply wafers or other materials on a timely basis could harm our business and our financial results.
  • Failure to adjust our purchase commitments and inventory management based on changing market conditions or customer demand could result in an inability to meet customer demand or additional charges for obsolete or excess inventories or non-cancellable purchase commitments or reduced sales in periods when customers digest excess inventory.
  • The cyclical nature of the semiconductor industry may limit our ability to maintain or improve our net sales and profitability.
  • Substantial portions of our sales are made to automotive industry suppliers. Downturns or disruptions in the automotive market or industry have harmed, and in the future could significantly harm, our financial results.
  • Acquisitions of other companies or technologies, may create additional risks, including risks associated with our ability to successfully integrate these acquisitions into our business.
  • Our gross margins may be adversely affected by decreases in average selling prices of our products, increases in input costs and shifts in product, customer or channel mix.
  • If we encounter sustained yield problems or other delays at our third-party wafer fabrication facilities or in the final assembly and test of our products, we may lose sales and damage our customer relationships.
  • Our quarterly net sales and operating results are difficult to predict accurately and may fluctuate significantly from period to period. As a result, we may fail to meet the expectations of investors, which could cause our stock price to decline.
  • Our dependence on our manufacturing operations in the Philippines exposes us to certain risks that may harm our business.
The other 30 risks
  • A significant portion of our net sales are generated through distributors, which subjects us to certain risks.
  • Events beyond our control impacting us, our key suppliers, our manufacturing partners or other third-party suppliers of components, materials or subassemblies incorporated into the same end products as our devices could have an adverse effect on our business, financial condition, results of operations and cash flows.
  • If we fail in a timely and cost-effective manner to develop new product features or new products that address customer preferences and achieve market acceptance, our operating results could be adversely affected.
  • We depend on growth in the end markets that use our products. Any slowdown in such growth, including as a result of volatility in demand for emerging technologies or changes in government incentives, could adversely affect our financial results.
  • The loss of one or more significant customers could have a material adverse effect on our business and results of operations.
  • Our ability to identify, enter and expand in new markets may be unsuccessful, and our investments in these opportunities may not generate expected returns, which could adversely affect our business and financial results.
  • The nature of the design win process requires us to incur expenses without any guarantee that research and development efforts will generate net sales, and even if design wins are secured, such design wins may not generate timely or sufficient net sales or margins, which could adversely affect our financial results.
  • Changes in government trade policies, including the imposition of export restrictions and tariffs or retaliatory measures in response to such actions, could limit our ability to sell products to certain customers or limit demand from certain customers, which may materially and adversely affect our sales and results of operations.
  • Warranty claims, customer quality claims, product liability claims and product recalls could harm our business, results of operations and financial condition.
  • Our dependence on international customers and operations also subjects us to a range of other additional regulatory, operational, financial and political risks that could adversely affect our financial results.
  • We may lose sales if we are unable to obtain government authorization to export certain technology for our products, and we will be subject to legal and regulatory consequences if we do not comply with applicable export control laws and regulations.
  • Changing currency exchange rates may adversely affect our business, financial condition, results of operations and cash flows.
  • Our ability to raise capital in the future may be limited and could prevent us from executing our growth strategy.
  • Our indebtedness may limit our flexibility to operate our business and adversely affect our financial health and competitive position.
  • We depend on key and highly skilled personnel to operate our business, and if we are unable to retain our current personnel and hire additional personnel, our ability to achieve our long-term strategic business and financial objectives and execute our business plan could be harmed, which in turn could adversely affect our financial results.
  • Future sales of our common stock by large stockholders, or the possibility of such sales, may cause the trading price of our common stock to decline.
  • Our business and operating results could be harmed as the result of undertaking restructuring activities.
  • Risks Related to our Information Technology, Intellectual Property (“IP”), AI Technologies, and Data Security and Privacy
  • If we are unable to protect our proprietary technology and inventions, our ability to compete successfully and our financial results could be adversely impacted.
  • Our ability to compete successfully depends in part on our ability to commercialize our products without infringing the patent, trade secret or other IP rights of others.
  • Cybersecurity incidents that we or our critical third-party service providers experience could irreparably damage our reputation and business and materially affect our operating results and financial condition.
  • We are exposed to risks related to the use of AI Technologies by us and others.
  • We are subject to governmental regulation and other legal obligations, particularly related to privacy, data protection and information security, and consumer protection laws across different markets where we conduct our business. Our actual or perceived failure to comply with such obligations could harm our business.
  • Risks Related to Regulatory Compliance
  • Failure to comply with the large body of laws and regulations to which we are subject could adversely impact our business.
  • Our use of AI subjects us to a legal framework that is rapidly evolving and our failure to monitor and comply with the laws and regulations to which we are or may become subject could have a material adverse effect on our business and operations.
  • Our failure to comply with anti-corruption and anti-bribery laws could subject us to penalties and other adverse consequences.
  • In order to comply with environmental and occupational health and safety laws and regulations, we may need to modify our activities or incur substantial costs, and such laws and regulations, including any failure to comply with such laws and regulations, could subject us to substantial costs, liabilities, obligations and fines, or require our suppliers to alter their processes.
  • General Risks
  • We could be subject to changes in tax rates or the adoption of new tax legislation, whether in or out of the United States, or could otherwise have exposure to additional tax liabilities, which could adversely affect our results of operations or financial condition.
  • Failure to comply with requirements to maintain effective internal control over financial reporting could have a material adverse effect on our business and stock price.
  • Sustained inflation could have a material adverse effect on our business, financial condition, results of operations and liquidity.

Legal proceedings

From time to time, we may be involved in claims, regulatory examinations or investigations and legal proceedings arising in the ordinary course of our business. The outcome of any such claims or proceedings, regardless of the merits, and the Company’s ultimate liability, if any, is inherently uncertain. These claims, even if not meritorious, could result in the expenditure of significant financial and managerial resources.

We are not currently party to any material legal proceedings, and we are not aware of any pending or threatened legal proceeding against us that we believe could have a material adverse effect on our business, operating results, cash flows or financial condition.
