Our mission is to be the global leader in semiconductor technology with magnetic sensing and power solutions that drive e-Mobility, clean energy and automation.

Company Overview

The Company is a leading global designer, developer, fabless manufacturer and marketer of sensor integrated circuits (“ICs”) and application-specific power ICs, enabling the most important emerging technologies in the automotive and industrial markets. With the broadest portfolio of magnetic sensor IC solutions available, underpinned by our strong position in the automotive market, we are the leading magnetic sensor supplier worldwide based on market share. Our products are foundational to automotive and industrial electronic systems. Our sensor ICs enable our customers to precisely measure motion, speed, position and current, while our power ICs include high-temperature and high-voltage capable motor drivers, power management ICs, light emitting diode (“LED”) driver ICs and isolated gate drivers. We believe that our technology expertise, combined with our deep applications knowledge and strong customer relationships, enable us to develop solutions that provide more value to customers than typical ICs. Compared to a typical IC, our solutions are more integrated, intelligent and sophisticated for complex applications and easier for customers to use.

Growth in the global semiconductor industry is expected to be driven by technology mega trends in the automotive and industrial markets. These mega trends have created requirements for new technologies in vehicles, both in the powertrain and in the cabin, to support vehicle electrification and advanced driver assistance systems (“ADAS”). These shifts also require technology to enable intelligence and automation in factories and energy efficiency in robotics, data center and clean energy applications. According to industry experts, these mega trends are expected to increase the demand for sensing and power solutions like those we develop. We believe our patented portfolio of sensor and power ICs provides the underlying technology required to win in the presence of larger competitors.

Our longstanding history of innovation in the semiconductor industry is built on our market leading magnetic sensor IC technology. Our “first of its kind” approach took the complexity of magnetic systems design and embedded it within our solutions, dramatically simplifying customers’ design efforts while increasing system reliability. This is a pattern we have repeated over consecutive generations of products, enabling us to establish a strong presence in the most rigorous and demanding automotive markets. Our portfolio now includes more than 1,500 products, and we ship approximately 1.5 billion units annually to more than 10,000 customers worldwide. By developing sophisticated, analog mixed-signal IC solutions that incorporate our patented intellectual property and robust proprietary process technologies with our unique packaging know-how, we believe we are well-positioned to compete across all of our target markets and leverage our existing strengths in order to expand into new markets. Our established position as an incumbent supplier for the automotive market and our long product life cycles attest to the strength of this competitive advantage.

Our value proposition is based on providing complete IC solutions for motion control and energy efficient systems. This includes sensing angular or linear position, driving an electric motor or actuator, and regulating the power applied to sensing and driving circuits so they operate safely and efficiently. These capabilities are based on fundamental technical advances we have made in the field of Hall-effect and magnetoresistive (“xMR”) sensors and Bipolar-CMOS-DMOS (“BCD”) power ICs. We continue to be instrumental in developing magnetic transducers and power devices on silicon, application-optimized packaging, high-temperature operation, high-speed precision signal paths for signal processing, safety and reliability all on 100-volt (“100V”) capable BCD wafer technology. We also offer tunneling magnetoresistance (“TMR”) sensor solutions that provide the highest magnetic sensitivity, lowest power consumption, and the smallest size by comparison to other magnetic technologies. In Hybrid Electric Vehicles (“HEV”) and Electric Vehicles (“EV”) with ADAS, these innovations translate to increased driving range for EVs, smaller and more reliable power conversion systems, and improved safety and efficiency of on-board chargers, DC-DC converters and battery management systems, as well as safer and more reliable steering and braking systems. Our ICs can be found in seat and battery cooling applications in addition to motors, fans and pumps in conventional and electric vehicles. In the industrial market, these technologies enable energy efficiency and improved performance in clean energy, server and data center, robotics and automation applications. These innovations improve reliability to avoid factory downtime, accurately measure current to support increased energy efficiency or improved motor control and reduce the solution footprint to lower total system cost.

We have maintained our sensor IC leadership and built our power IC business through successfully developing deep customer relationships over time. We commonly collaborate with customers early and over a multi-year period to design products capable of meeting demanding performance and quality requirements. Through this customer collaboration in product design, we believe we have unique insight into market trends and customer requirements for new, improved and innovative products. We believe that these insights enable us to develop differentiated solutions, often in advance of our competitors.

Our customer list includes virtually all of the world’s top automotive companies by market share and a large number of leading industrial companies. We are a preferred vendor to tier-one suppliers in the automotive industry that supply parts or systems directly to original equipment manufacturers (“OEMs”). We are also a preferred partner or vendor to many global OEMs. Our products can be found in vehicles built by nearly every automotive OEM worldwide and in many common industrial systems. We support customers through design, application and customer support centers located in North America, South America, Asia and Europe. Our local teams in these centers work closely with our customers on their unique design requirements, often acting as an extension of a customer’s development team.

Our strategy to extend our market leadership in high-growth markets, increase our IC design footprint and capacity, and accelerate growth through enhanced sales operations relies on a fabless and asset-lite manufacturing model. We use external wafer manufacturing consisting of both standard and proprietary processes, along with internal and external assembly and test capabilities to provide both flexibility and scale. Through our subcontractor manufacturers, we are able to employ our proprietary wafer fabrication processes while leveraging our subcontractors’ manufacturing technologies and high-volume capacity. Our use of both internal and external assembly as well as test capabilities is designed to balance the protection of our proprietary technology and processes while achieving automotive quality manufacturing at scale.

Our Market

Within the global semiconductor industry, we focus on the magnetic sensor and power management IC markets.

E-Mobility

We define e-Mobility as the electrification of vehicles, including HEV and EV powertrains, and the increasing adoption of safety-focused ADAS. Recently, we are seeing increasing demand for our power products based on our 100V process technology as a result of the transition to 48V electrical architectures in electric and hybrid electric vehicles.

We are a leading provider of sensing and power solutions for vehicle electrification, building on our decades of experience in conventional powertrain efficiency and performance leadership in technologies that reduce emissions. The ability to improve efficiency is critical as OEMs strive to comply with emissions regulations and heightened customer awareness of the environmental impact of high emissions and the desire for extended driving range per charge.

As HEVs and EVs become a meaningful share of the automotive market, OEMs face challenges and opportunities to change system architectures to reduce complexities while achieving optimal energy efficiency and vehicle range. This presents several new opportunities for semiconductors, and we expect our content per vehicle will continue to increase, driven by research and development innovation to serve this high-growth market.

As an expert in delivering ICs supporting efficient power conversion in HEVs and EVs, we believe we are uniquely positioned to support increased electrification, providing the critical automotive-grade components required to enable energy-efficient and cost-effective vehicles. We believe this allows us to take advantage of the significant semiconductor content increases expected to result from the HEV and EV migration and strong growth of electrified powertrains over the coming years.

TMR technology bolsters our current sensor and position sensor product portfolio and solidifies our leading magnetic sensing market position. TMR technology enables the highest magnetic sensitivity, lowest power consumption, and the smallest size by comparison to other magnetic technologies. We believe our TMR products, which we market under the name XtremeSense™, are an ideal fit for the electric powertrain, steering and braking systems in vehicles, which require higher accuracy, greater bandwidth and lower power consumption.

Our high voltage power portfolio provides us with additional content opportunities in both HEV and EV powertrains, high-efficiency data center power supplies, clean energy power conversion systems, and in motors throughout highly automated factories. This first-to-market technology, which integrates an isolated DC-DC converter and isolated gate drivers (“IGD”) is more efficient than competitive solutions that require two chips. This not only allows customers to reduce the size of their printed circuit boards (“PCBs”), but also enables the entire system, like an on-board charger system, to shrink. We continue to innovate this technology, which will enable gallium nitride (“GaN”) and silicon carbide (“SiC”) solutions for electric vehicle powertrains and high-efficiency industrial applications.

ADAS capabilities are considered some of the most desirable features in modern vehicles and continue to be adopted in vehicles worldwide. Industry experts expect ADAS feature adoption to continue to increase over time. ADAS is a precursor to fully autonomous vehicles. While many ADAS-equipped vehicles are being produced today, as ADAS features become more sophisticated and increasingly adopted, demand for our sensor and power ICs is expected to expand in steering and braking systems. Based on industry forecasts, we believe the transition to vehicles that incorporate ADAS Level 1 through 5 technologies will drive strong adoption of sensors and power management products to support these vehicles, which in turn will enable us to increase our total available market related to ADAS and related safety and chassis technologies.

Our devices play a key role in ADAS applications, reacting to system inputs to enable collision avoidance, lane keep assist, automatic emergency braking and self-park features through automatic steering and braking. A steering system equipped with even a modest degree of automation utilizes products across our entire portfolio, including sensors, power management ICs and motor driver ICs, which we believe is indicative of the size of our potential market opportunity as ADAS applications become increasingly more sophisticated.

Adoption of ADAS technologies continues to grow, and our solutions do not require waiting for widespread adoption of fully autonomous vehicles. We already ship a significant volume of devices every year that enable ADAS capabilities in both EV and internal combustion engine (“ICE”) powertrains. Vehicles equipped with Level 1 ADAS feature sets (i.e., the capability to take control of one functionality) already use Allegro devices. For years, we have been at the forefront of enhancing safety features in ADAS applications, particularly steering and braking systems through continuous innovation and close collaboration with automakers. Our proven record of supplying devices for safety applications and experience with supporting ADAS features in high-end vehicles, combined with growing adoption of ADAS from luxury vehicles to mainstream and economy vehicles, positions us to capitalize on this rapidly expanding market opportunity.

Traditional Automotive Applications

ICE will continue to exist in some form for the foreseeable future, either in pure ICE vehicles or HEVs. OEMs continue to improve their fuel efficiency and look to Allegro to help create the most efficient ICE powertrains possible. We have decades of experience as a proven supplier in ICE powertrains to support fuel efficiency.

Our safety, comfort and convenience business, commonly referred to as body electronics, will continue to evolve with vehicle electrification, which we believe leads to more content opportunities. Systems that historically relied on engine temperature or mechanical energy are now electrifying, and new system technologies are being rolled out. New systems increase the number of fans, pumps and motors in vehicles, thereby increasing our content opportunity. We also enable safer and more energy efficient lighting and infotainment systems as we develop more advanced products and innovate with our customers.

Clean Energy and Cloud Computing

Our automotive first philosophy resonates with our industrial customers who appreciate our rigorous quality standards, devices designed to withstand extreme environments and our long product lifecycle of 10 years or more. These customers are in our target markets of clean energy and cloud computing, defined as renewable energy generation, storage and distribution, EV charging infrastructure plus data center cooling systems and power supplies.

Renewable energy, especially solar, and EV charging infrastructure are being driven by the increased electrification of a variety of products and processes and government regulations to reduce emissions. Having the technology and products to support these markets from their infancy provides us with an advantage to help customers bring their products to market more quickly. This enables us to work closely with our customers and solve challenges as they arise.

We offer one of the largest portfolios of current sensors on the market today, including those with integrated components, requiring less board space. Our “lossless” current sensor ICs are used to improve efficiency in power conversion systems and power supplies. Our 100V BCD wafer process technology and galvanically isolated current sensors are suited for higher voltage operation, and we believe the demand for current sensor ICs will increase as more solar inverters, EV chargers and data servers come to market. As the industry transitions to 48V power architectures in the data center market, our sensors and power ICs are being adopted to further improve energy efficiency enabled by this wafer process technology. In addition, we expect our GaN and SiC based IGD technology to have a strong presence in these power conversion systems with the use of a single, small-footprint package to significantly reduce system complexity while increasing efficiency.

Our motor drivers continue to be used in data center cooling applications, mainly for thermal efficiency, as these products reduce complexity and design time, while also reducing the energy consumption required to cool servers. With the advent of generative artificial intelligence, we anticipate continued growth for our motor drivers in systems for air and liquid cooling of server components.

Automation

With the growing adoption of factory automation, there is increasing demand for precise motion control and energy efficient technologies presenting additional meaningful growth opportunities for us. Robotics is an area of high market growth through increased adoption of warehouse robots, assembly robots, collaborative robots, cleaning robots and humanoid robots. Customers already leverage our technology leadership in solutions optimized for high-accuracy, high-voltage and high-reliability conditions allowing us to expand our presence in these markets. Many of these applications require the same safety and accuracy specifications that we have designed into our automotive-first devices. In particular, we believe we have the potential to leverage synergies between our power and sensor solutions, including motor drivers, voltage regulators, and current, position and speed sensors, in under-penetrated opportunities within industrial automation.

Broad Industrial

The Broad Industrial market includes our personal mobility, or two-wheeler market, and a broad variety of other use cases from heavy equipment to telecom connectivity. Our two-wheeler business is seeing similar electrification trends as larger vehicles. Our solutions are proven in electrified powertrains and in the small form factors needed in these applications. These markets are looking for many of the same device specifications that our automotive customers use, from high voltage and high temperature performance to long life cycle, small form factors, integration and unique packaging. Our automotive quality standards result in solutions that provide robust, high performance over long lifecycles, garnering trust from our industrial customers.

Consumer Markets

The consumer markets include smart home applications, gaming, personal medical devices and consumer electronics. Our devices enable our customers in these markets to manufacture more robust and more energy-efficient products with extended battery life.

Market Opportunity

Within our target markets, a key element of our growth strategy is to increase our revenue through portfolio and customer expansion. We are a market share leader in the magnetic sensor IC market, and we believe there is considerable opportunity to continue to grow this foundational business. Recently we introduced new position sensor ICs and quickly ramped up revenue in motion control applications, particularly in the ADAS market. These position sensors, especially angle sensors, are also used in robotic motion control systems, extending the synergy to industrial applications. Our industry’s highest bandwidth current sensors are a core component in many automotive and industrial applications alike for current monitoring and efficient power conversion. We believe similar share growth opportunities exist in other adjacent areas of the magnetic sensor IC market. We also plan to grow in the magnetic sensor market through the release of more products based on our XtremeSense TMR technology.

We are also leveraging our power IC products to increase our total content within automotive and industrial applications. Designing power products specifically for ADAS and data center is part of our strategy to focus on megatrends of electrification, safety, and energy efficiency. We believe there is more opportunity for us to expand our offerings, as electrified vehicles will require more motors to run pumps and fans and as data center architecture continues to evolve to incorporate more fans, higher power fans, and advanced liquid cooling solutions.

Our latest opportunity to expand our market presence is with both our IGDs and our XtremeSense TMR technology. IGD solutions have applications in power conversion in EVs, such as on-board chargers and traction inverters, as well as in clean energy systems. Our XtremeSense TMR products have applications beyond our traditional markets, for example in continuous glucose monitoring within the personal medical market.

Increasing our Served Available Market (“SAM”)

Another focus of our growth strategy is to significantly expand our served available market by using our established position in high-value automotive and industrial applications to increase our content per system. We believe the automotive market is very attractive due to the rigorous quality and safety requirements that create meaningful challenges for new competitors and the significant technology shifts currently underway that are expected to meaningfully increase semiconductor content per vehicle.

Part of our served available market expansion is through acquisitions that open new sockets and new applications to us.

With the growth of semiconductor content opportunities related to EV and ADAS penetration already accelerating, we have seen significant increases in our electronic system content per vehicle. For example:

•

Our opportunity for vehicles adopting ADAS features is expected to grow as the adoption moves from high-end vehicles to mid- and lower-range vehicles. An additional benefit from ADAS is the content opportunity increase per system as new architectures are adopted. We believe that moving from today’s systems to electromechanical braking and steer-by-wire will nearly double the devices required per system.

•

According to our internal estimates and third-party sources, we believe that we have a total opportunity of up to approximately $100 of potential content in each battery EV or plug-in EV. The content opportunity in EV and plug-in EV is 2.5 times the content in a typical ICE vehicle.

There is a similar dynamic in the industrial market, where clean energy and automation are two mega trends requiring more semiconductor content as they gain mainstream adoption. Our current sensors, motor drivers position sensors and IGDs’ performance and reliability make them uniquely capable of delivering on customer expectations for both energy efficiency and motion control.

The robotics market is rapidly transforming and presents a new potential growth opportunity for both our sensor and power ICs. Joints in robotic arms could include several of our leading products, most commonly motor drivers to actuate the joint, and sensors for position feedback and optimized motor control. As more advanced robots are adopted at scale, the SAM expansion opportunity for us could be significant.

Our direct sales force and applications engineers provide our customers with specialized technical support. We believe that maintaining a close relationship with our customers and serving their specific technical needs improves their level of satisfaction and enables us to anticipate and influence their future product needs. We provide ongoing technical training to our distributor and sales representatives to keep them informed of our existing and new products.

We maintain an internal marketing organization that is responsible for increasing our brand awareness and promoting our products to prospective customers. This includes the creative management of our website, market research and analytics, and development of demand generation strategies and materials, such as product announcements, press releases, brochures, training and videos, as well as securing thought leadership through published technical and trend articles and advertisements, and active engagement in key industry events.

Customers

We sell our products to major global OEMs and their key suppliers, primarily in the automotive and industrial markets. We sold to more than 10,000 end customers, directly and through distributors, during each of fiscal years 2025, 2024 and 2023. Approximately half of our net sales during each of fiscal years 2025, 2024 and 2023 were derived from sales to our top 20 customers, which includes distributors. We believe that no end customer, including those served through our distributors, exceeded 10% of our net sales during fiscal years 2025, 2024 and 2023.

Research and Development Strategy

We are a technology company, and we believe our future success depends on our ability to rapidly develop and introduce differentiated new products in our target markets. As a result, we are committed to investing in our process and product development capabilities while focusing our engineering efforts on designing and introducing new application-specific products, developing new semiconductor process and packaging technologies, enhancing design productivity and evaluating new technologies. Our research and development investments are subject to a rigorous ROI review to ensure alignment with our growth and profitability targets. We believe that by effectively applying these resources, we have developed proprietary innovations and intellectual property that will give us an early lead in our target markets and will enable accelerated growth over time.

Over the last 10 years, we believe we have been instrumental in achieving fundamental developments that have enabled a number of key technology transitions in the automotive and industrial markets. We believe we are one of very few suppliers in the semiconductor industry to integrate proprietary motor control algorithms into our motion control devices to achieve optimized BLDC motor performance. We remain one of the few suppliers who has developed multiple packaging technologies capable of operating at temperatures of up to 175 degrees Celsius and including passive components and high current conductors required to make high-efficiency, high voltage current sensor products. We were also one of the first in our industry to develop automotive grade xMR technology on silicon wafers, which enabled breakthrough advances in product performance. This advanced technology is a key enabler across all of our strategic focus areas in the automotive and industrial markets as more of the e-Mobility and clean energy markets transition to xMR.

We augment our internally generated intellectual property through a mix of licensed intellectual property, partnering with industry experts, and through acquisitions. For example, the two businesses we acquired in the past three years provide leading technology, including TMR and IGD, which will expand our serviced available market, most notably in EV and clean energy.

Our global team of highly skilled engineers has extensive semiconductor development experience, including expertise in analog design, test and process technology. As of March 28, 2025, we had approximately 750 employees dedicated to research and development, with centers in the United States, Europe, South America, and Asia. The efforts of our engineering team and our strategic acquisitions have resulted in our intellectual property portfolio nearly doubling over the last three years, further strengthening our position in our target markets.

We have also made significant investments in our core engineering capabilities, including improvements in tools to support greater engineering efficiency, as well as electrical component, magnetic performance and thermal distribution modeling. We believe these improved tools enable us to more accurately evaluate and predict the performance of our designs, resulting in accelerated time-to-market for our products and satisfaction of our customers.

Our focus on meeting or exceeding the stringent automotive market safety and reliability requirements is fundamental to our research and development process. We anticipate that we will continue to make research and development investments in order to enhance our leadership position and expand our markets with innovative, high-quality products and services (as exemplified through our acquisition of IGD power group and TMR technology). In addition, our Board has a standing Strategy Committee, whose purpose is to provide leadership and guidance to management on defining and implementing the strategic direction of the Company.

Process and Packaging Technology

Our product and technology development engineers have long-established expertise in designing mixed signal power and magnetic sensor ICs using proprietary semiconductor process technologies and intelligent packaging. We consider these capabilities to be strategically important because they allow us to create complete system products and highly integrated solutions that meet the quality and robustness requirements of our most stringent automotive customers and applications. These have the benefit of advancing the feature, function and cost of ownership of our devices relative to those of our competitors. For example, we released a unique 100V- and 175-degree Celsius capable BCD wafer technology designed to handle automotive voltage and temperature transients while also integrating high-density logic circuits and electrically erasable programmable read-only memory to enable configurable and embedded algorithms, and various Hall-effect and xMR transducer technology on the same silicon wafer. These technologies are fundamental to the transition from 12V to 48V power supply required in the rapidly emerging HEV and EV markets, and to the next generation of ADAS systems. We are in the process of applying these capabilities to the industrialization of our IGD portfolio.

In choosing the process technology to be used to manufacture a new product, we seek to optimize the match between the process technology and the desired performance parameters of the product for our customers. Our current strategic semiconductor process innovations include the following:

Automotive Quality and Safety

We have developed, characterized and qualified our wafer and package technologies to meet or exceed the rigorous automotive requirements that our customers demand. Robust development processes and guidelines have resulted in devices capable of exceeding the requirements of AEC Q100 Automotive Grade 0 of 150 degrees Celsius, and our field failure rates are consistent with or better than customer requirements.

Integrated Transducers

One of our fundamental innovations is the integration of magnetic transducers and complementary metal oxide semiconductor circuitry into one piece of silicon to create a complete, fully integrated system. Hall-effect elements are implanted in silicon, providing robust and low noise solutions that are optimized for stress and temperature effects. Thin film, high-resolution xMR transducers are deposited directly on top of the complimentary metal-oxide semiconductor (“CMOS”) circuitry creating a more reliable solution than multi-chip solutions by reducing interconnects and solution area. To achieve the highest level of Automotive Safety Integrity Level (“ASIL”), we are able to integrate xMR and Hall-effect transducers onto the same silicon to produce heterogeneous solutions capable of performing reliably in the most demanding automotive environments.

High-Voltage Technology

Our intellectual property, developed over years of experience in automotive applications includes advanced mixed-signal integration of high-voltage solutions with our high-precision analog designs. For example, our innovative wafer technology enables 100V capable power transistors to be combined with embedded digital logic and precision analog circuits on a monolithic motor control IC suitable for emerging 48V automotive applications. This enables a number of application-specific advancements, including taking the complex algorithm development in motor drivers into the IC, vastly reducing our customers’ design complexity and creating the most efficient and quietest solutions in the market. Similar benefits exist for our sensor products through monolithic integration of transducers with precision analog circuits and intelligent signal processing on a high-voltage IC that can be powered from a vehicle battery.

Advanced, Small Form Factor Integrated Packages

We continue to combine circuit design and process innovation with novel packaging solutions that improve performance and reliability while reducing solution footprint and our customers’ cost of ownership. Two decades of sensor package innovation have led to the development of a family of integrated systems in a package for magnetic current, position and speed sensor ICs. By integrating a combination of a magnet, magnetic core, passive components, and our silicon integrated circuit in a single body, we are able to offer inventive magnetic sensors that reduce our customers’ needs to design complex magnetic models or complex interface circuits, solve electrical interference issues with external PCBs, and enable smaller and more cost-effective customer systems. The current sensors integrate specially designed lead frames to allow a high-precision, factory-programmed single package solution that provides a unique high-efficiency and high-voltage isolation product and can sense current for products plugged directly into a household electrical outlet or connected to an 800-volt automotive battery. Years of design and manufacturing refinement have led to the latest generation of power products that integrate passive components and power conversion capabilities into small packages to reduce PCB footprint, reduce electromagnetic noise, and improve efficiency in high-power systems. Our IGDs also incorporate a DC-DC converter, a small planar transformer, and a gate driver into a small form factor package. Through innovative package integration, these IGDs minimize parasitic capacitance and significantly improve system level efficiency in electrified vehicles, clean energy, and factory automation systems. We also believe we are one of only a few companies in our industry that have developed a broad portfolio of packages that are suitable for operation in automotive environments and 175-degree Celsius temperatures.

Intellectual Property

We consider the strength of our intellectual property portfolio to be a significant competitive advantage. Our intellectual property includes patented inventions, trade secrets, accumulated technical know-how and trademarks. As of March 28, 2025, we owned 1,942 active patents, including 966 U.S. patents (with expiration dates between 2025 and 2043), with an additional 487 pending patent applications, including 252 U.S. patent applications.

We market our products worldwide under the “Allegro” name. We either hold or have applied for trademarks in all jurisdictions where we do significant business.

Competition

The semiconductor industry, particularly the market for high-performance analog mixed-signal semiconductors, is highly competitive. Although no one company competes with us across all of our product lines, we face significant competition within each of our business areas from both domestic and international semiconductor companies. Our primary magnetic sensor and power IC competitors are other semiconductor designers and manufacturers, such as Analog Devices, Infineon, Melexis, Monolithic Power Systems, TDK Micronas, and Texas Instruments.

Our ability to compete successfully against these companies depends on elements both within and outside of our control. Some of our competitors have substantially greater financial, technical, marketing and management resources than we have. These competitive advantages may enable them to respond more quickly to new or emerging technologies or changes in customer requirements, or better position them to withstand adverse economic or market conditions.

We believe we can successfully compete against these organizations in our target markets by leveraging our design and market expertise and leadership position, proprietary manufacturing processes, custom packaging capabilities and close customer relationships. In addition, we compete in our target markets to varying degrees on the basis of a number of competitive factors, including:

•

time to market;

•

system and application expertise;

•

product quality and reliability;

•

quality systems and support;

•

product features and performance;

•

proprietary technology;

•

production capacity; and

•

solution price.

We believe we currently compete favorably with respect to these factors. However, we cannot assure you that our products will continue to compete favorably or that we will be successful in the face of increasing competition from new products and enhancements introduced by existing competitors or new competitors entering our markets. See “Risk Factors—Risks Related to our Business and Industry—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.”

Seasonality and Market Demand

Our business exhibits some seasonality. Historically, our net sales have generally been higher in the second half of the fiscal year than in the first half. However, various factors, such as market conditions, the cyclicality of the semiconductor industry, new product introductions and the supply chain environment, can impact the effects of seasonality on our business.

Over the past several quarters, we and other semiconductor companies have experienced a downturn in market demand, primarily driven by softening demand from customers across various markets and digestion of excess accumulated inventory. In addition, factors that cause a reduction in the demand from end users of our OEMs’ or other customers’ products, including as a result of increased prices resulting from global trade policies, tariffs or a recessionary environment in the markets in which we operate, may in the future continue to cause our direct customers to significantly reduce the number of products ordered from us.

Employees and Human Capital Resources

Our employees are our most valuable assets and contribute to Allegro’s success. We have a skilled and experienced workforce across research and development, operations and quality, sales and marketing and our general and administrative support functions. Together as “One Allegro,” our employees are instrumental in driving operational execution and quality excellence, delivering strong financial performance, advancing innovation, and building trusted customer relationships to help solve our most complex problems.

As of March 28, 2025, we employed approximately 4,060 full-time employees, including 750 in research and development, 2,800 in operations and quality (the overwhelming majority located at our facility in Manila, Philippines (the “AMPI Facility”)), 230 in sales and marketing and 280 in general and administrative. We consider our relationship with our employees to be good, as we have never experienced a labor-related work stoppage. None of our employees are represented by a labor union.

The success and growth of Allegro’s business is dependent in large part on our ability to attract, retain and develop talented and high-performing employees from various backgrounds at all levels of our organization. We continue to make talent investments in our centers of excellence and global design centers in order to attract top analog design talent to drive future innovation. We have a technical ladder across our engineering disciplines to promote a robust career path opportunity for our highly valued engineering employees. Additionally, we offer a specific Field Applications Engineer training in partnership with sales and other departments to educate teams on our many products.

For our research, engineering, and production management positions, we require employees with university and graduate-level degrees. As of March 28, 2025, approximately 2,300 of our employees held university and graduate-level degrees, of which 990 of these employees were located outside of our factory locations. Globally, the demand for employees with such levels of education is high and competitive.

To succeed in these conditions, Allegro implements key recruitment and retention strategies, objectives and effectiveness measures as part of the overall management of our business. These core strategies are advanced through the following programs, policies and initiatives:

Competitive Pay and Benefits. Allegro’s compensation programs are designed to align the compensation of our employees, who operate in a highly competitive and technologically challenging environment, with Allegro’s business performance and to provide the proper incentives to attract, retain and motivate employees to achieve superior performance. The structure of our compensation programs provides incentive earnings for both short-term and long-term performance. Specifically, and as applicable to individual employees and roles:

•

We provide short-term incentive and equity awards based on both business and individual performance.

•

We also provide an opportunity for many of our global employees to earn equity awards. Additionally, in the U.S. and the United Kingdom, we offer an employee stock purchase plan to our non-executive employees, which allows them to purchase shares of Allegro stock at a discounted price. This stock purchase plan further aligns our employees’ financial interests with the performance of the business and the interests of our stockholders.

•

We purchase compensation data from external compensation and benefits consulting firms to ensure we provide competitive compensation in each of the geographic locations in which we operate.

•

We align our executives’ annual and long-term equity compensation, in the form of performance-based restricted stock units (“PSUs”) and time-based restricted stock units (“RSUs”), with our stockholders’ interests by linking realizable pay with Allegro’s stock performance and other key business and financial operating metrics.

•

We provide comprehensive benefit options designed to retain our employees and support their families in all areas of health and wellness.

•

We provide social community benefits, including a global charitable gift matching program, and a global volunteer policy, both of which help our employees give back to the local communities in which we operate.

Employee recruitment, retention and development. Allegro works diligently to attract the best talent from a broad array of sources to meet the current and future demands of our business. We have established relationships with world-class colleges and universities, professional associations and industry groups to proactively attract talented and capable new hires. We also utilize social media, local job fairs and educational organizations to find motivated and responsible candidates who represent a variety of backgrounds, perspectives and experiences. We have also made strides in expanding the breadth of qualified talent pools we draw from to find candidates for management positions, while building internal resources to support our employees, regardless of background, to qualify for future leadership openings. Allegro has a strong employee value proposition that leverages our technology leadership, collaborative working environment, shared sense of purpose and culture, and the desire to do the right thing to attract talent to our Company.

We closely monitor employee turnover rates, as our success depends upon retaining and investing in our highly trained manufacturing and technical staff. Allegro strives to decrease employee-initiated voluntary turnover and increase employee retention through a combination of competitive compensation, individual developmental opportunities and personal career enrichment and growth. We strive to provide an inclusive culture where employees can come to work, feel a sense of belonging and achieve their personal best. We provide a Flex@Allegro program to allow our employees flexibility as to where and how work gets accomplished. This flexible work arrangement enables our employees to achieve better work and life balance, and helps us to attract and retain talent. Our retention at the technical, professional and managerial levels is high, and our voluntary turnover remains lower than industry averages based on benchmark data.

Employee Engagement. At Allegro, we strive to create a positive, values-based culture and high employee engagement where our employees can bring their best to work. In fiscal year 2025, we launched our second annual global employee engagement survey to all employees, and achieved a high participation rate, indicating employees see value in sharing their perceptions and sentiments about working at Allegro. Our engagement score for fiscal year 2025 is on par with industry benchmarks, and the survey found that the large majority of employees would recommend Allegro as a great place to work and are proud to work at Allegro. In addition, the majority of employees feel that the products and services we offer are as good or better than our competitors, driving pride in the organization and passion for what we build and deliver.

Environmental and Occupational Health and Safety Regulation

We recognize the importance of protecting the environment and the health and safety of our employees, customers, and communities. Our Environmental Health and Safety (“EHS”) Policy outlines policies and training programs that are designed to promote and protect employee safety. Our EHS teams oversee workplace conditions for our employees. All Allegro EHS policies and procedures are developed in accordance with applicable laws and regulations. Our AMPI Facility is certified to ISO 14001 for environmental management systems and ISO 45001 for occupational health and safety management systems.

Our operations are subject to various federal, state, local, international, and non-U.S. laws and regulations governing pollution and environmental protection and occupational health and safety, including those related to hazardous and toxic materials, product composition, and the investigation and cleanup of contaminated sites. This includes sites we currently or formerly owned or operated, due to the release of hazardous materials, regardless of whether we caused such release. In addition, we may be strictly liable for joint and several costs associated with investigation and remediation of sites at which we have arranged for the disposal of hazardous wastes if such sites become contaminated, even if we fully comply with applicable environmental laws and regulations. We are also subject to various federal, state, local, international, and non-U.S. laws and regulations relating to occupational health and safety. Any failure on our part to comply with these laws and regulations, including new laws or new interpretations of existing ones, may subject us to significant fines or other civil or criminal costs, obligations, sanctions or property damage or personal injury claims, or suspension of our facilities’ operating permits. In addition, in the event of an incident involving hazardous materials, we could be liable for damages and such liability could exceed the amount of any liability insurance coverage and the resources of our business.

We face increasing complexity in our product design and procurement operations due to the evolving nature of environmental laws, regulations, directives and standards, as well as specific customer requirements. These laws, regulations, directives, and standards have an impact on the material composition of our products entering specific markets. For example, the European Union (“EU”) adopted its Restriction of Hazardous Substance Directive (“RoHS”) legislation, EU Directive 2002/95/EC (RoHS) and 2011/65/EU (RoHS II), amended by 2015/863/EU, which took effect in July 2019. The EU also adopted the European Regulation on Registration, Evaluation, Authorization and Restriction of Chemicals (“REACH”) in 2007, which calls for the progressive substitution of dangerous chemicals in manufacturing. In 2006, China first published its RoHS equivalent, the Administrative Measures on the Control of Pollution Cause by Electronic Information Products. This regulation was revised in 2016 when China enacted the Administrative Measures on the Restrictions of the Use of Certain Hazardous Substances in Electrical and Electronic Products Regulations, which expanded the scope of the 2006 requirements and is designed to restrict additional hazardous substance in certain electrical and electronic products. In addition, any business selling products to consumers in California containing certain listed chemicals or substances is subject to California Proposition 65 (officially known as the Safe Drinking Water and Toxic Enforcement Act of 1986), which requires disclosure of the listed chemical and potential health risks. In addition to these regulations and directives, we may face costs and liabilities in connection with product take-back legislation, which holds manufacturers responsible for the collection and proper disposal of their products discarded by their customers. There are also increasing regulations regarding the use of green marketing claims, which may also affect our product design and procurement operations. Non-compliance with current or future regulations or directives could restrict our ability to expand our business or require us to modify processes and/or materials or incur other substantial expenses which could harm our business.

Although we incur costs to comply with the provisions discussed above and other applicable federal, state, local, international and non-U.S. laws and regulations relating to environmental protection in the ordinary course of our business, such costs have not materially affected, and are not presently expected to materially affect, our capital expenditures, earnings or competitive position.
