Industry Background

Wireless connectivity is expanding on a global basis. A widening range of use cases is driving the high demand for wireless data across a broad array of applications. The advancement of 5G adoption, IoT, connectivity for everyone, automotive electrification and safety, as well as augmented reality and virtual reality technology, all demand faster speeds, increased bandwidth and capacity, significantly lower latency, and more reliable and secure wireless connectivity.

The speed and ultra-low latency characteristics inherent in 5G technology are dramatically altering wireless connectivity, creating a market for diverse and transformative applications, and changing how individuals live, work, play, and learn. Most of the world’s largest economies have implemented commercial 5G networks, and the world’s leading smartphone manufacturers have launched multiple generations of 5G-enabled devices.

We expect to see a continued expansion in data consumption, dependent on seamless and reliable wireless connectivity. A few statistics illustrate this point. According to the 2025 Ericsson Mobility Report, global mobile data for 5G subscriptions are forecast to reach 6.3 billion by the end of 2030, driven by new users, innovative services, and the convergence of artificial intelligence (“AI”) and 5G technology, and the total number of global IoT connections is now forecast to reach approximately 43 billion by 2030, including connected cars, machines, meters, sensors, point-of-sale terminals, consumer electronics and wearables. Connected cars are forecasted by McKinsey to make up 90% of new vehicles sold globally by 2030.

Skyworks helps facilitate these opportunities with highly customized solutions that support a broad set of wireless systems and protocols including cellular (such as 5G), Wi-Fi®, GPS, Bluetooth®, Accutime™, HD-Radio™, LoRa®, Thread®, Wi-Sun®, and Zigbee®. Additionally, Wi-Fi® 8, the next generation of Wi-Fi® technology, complements 5G by providing high-speed wireless connectivity in local environments. Faster data rates and improved efficiency cater to the growing number of devices reliant on wireless networks.

We believe AI can be a catalyst for more efficient and effective wireless communications. From endpoint devices to data centers, generative AI applications will drive the need for higher speed and higher bandwidth networks, while increasing the requirements for our precision timing solutions.

The first wave of AI-capable phones is reaching scale, and early demand signals are encouraging. As AI capabilities become more intuitive and integrated, we believe this could drive an inflection in upgrade cycles, leading to a potential tailwind to volumes and content over time.

Finally, with the rapid transition towards electrification and advanced safety in vehicles, we are focused on high growth segments and content opportunities, including (i) power isolation chips for on-board chargers, powertrain, and battery management systems in electric vehicles, (ii) connectivity, with telematics and other solutions being enabled by 4G/5G cellular engines, Wi-Fi®, Bluetooth®, Ultra-wide band, Ethernet, and GPS, and (iii) in-vehicle infotainment systems, driven by digital radio coprocessors, and solutions supporting advanced driver-assistance systems and autonomous driving.

Further, the Company’s three largest accounts receivable balances comprised 82% and 80% of aggregate gross accounts receivable as of

October 3, 2025 and September 27, 2024, respectively. For further information regarding customer concentrations, see Note 14 to Item 8 of this Annual Report on Form 10-K.

Intellectual Property and Proprietary Rights

We own or have a license to use numerous United States and foreign patents and patent applications related to our products and our manufacturing operations and processes. In addition, we own a number of trademarks and service marks applicable to certain of our products and services. We believe that our intellectual property, including patents, patent applications, trade secrets, and trademarks, is of material importance to our business. We rely on patent, copyright, trademark, trade secret, and other intellectual property laws, as well as non-disclosure and confidentiality agreements and other methods, to protect our confidential and proprietary technologies, designs, devices, algorithms, processes, and other intellectual property. Our efforts may not meaningfully protect our intellectual property, or others may independently develop substantially equivalent or superior proprietary technologies, designs, devices, algorithms, processes, or other intellectual property. In addition, the laws of some foreign countries do not protect proprietary rights to the same extent as the laws of the United States, and effective copyright, patent, trademark, and trade secret protection may not be available in those jurisdictions. In addition to protecting our intellectual property, we strive to strengthen our intellectual property portfolio to enhance our ability to obtain cross-licenses of intellectual property from others, to obtain access to intellectual property we do not possess, and to more favorably resolve potential intellectual property claims against us. Due to rapid technological changes in the industry, we believe establishing and maintaining a technological leadership position depends primarily on our ability to develop new, innovative products through the technical competence of our engineering personnel.

Competitive Conditions

The competitive environment in the semiconductor industry is in a constant state of flux, with new products continually emerging and existing products approaching technological obsolescence. We compete on the basis of time-to-market, new product innovation, quality, performance, price, compliance with industry standards, strategic relationships with customers and baseband vendors, personnel resources, and protection of our intellectual property. We participate in highly competitive markets against numerous competitors that may be able to adapt more quickly to new or emerging technologies and changes in customer requirements, or may be able to devote greater resources to the development, promotion, and sale of their products.

Research and Development

Our products and markets demand rapid technological advancements requiring a continuous effort to enhance existing products and develop new products and technologies. Accordingly, we maintain a high level of research and development activity. We invested $785.5 million, $631.7 million, and $606.8 million in research and development during fiscal 2025, fiscal 2024, and fiscal 2023, respectively. The level of research and development expenses were the result of increases in our internal product designs and product development activity for our target markets in each of these fiscal years. Our research and development expenses include new product development and innovations in integrated circuit design, investment in advanced semiconductor manufacturing processes, development of new packaging and test capabilities, and research on next-generation technologies and product opportunities. We maintain close collaborative relationships with many of our customers to help identify market demands and target our development efforts to meet those demands.

Raw Materials

Raw materials for our products and manufacturing processes are generally available from several sources. It is our intent not to depend on a sole source of supply unless market or other conditions dictate otherwise. However, there are limited situations where we procure certain components and services for our products from single or limited sources, and we are currently dependent on a limited number of sole-source suppliers. We purchase materials and services primarily pursuant to individual purchase orders. However, we have entered into certain supply agreements for the purchase of raw materials or other manufacturing-related services that specify minimum prices and purchase quantity based on our anticipated future requirements. Certain of our suppliers consign raw materials to us at our manufacturing facilities to which we take title as needed in our manufacturing process. We have taken strategic action with suppliers located around the world to secure sourcing of the raw materials and components necessary for our manufacturing.

Backlog and Inventory

Our sales are primarily from the sale of semiconductor products under individual customer purchase orders, some of which have underlying master sales agreements that specify terms governing the product sales. In the absence of a sales agreement, the Company’s standard terms and conditions apply. Due to industry practice, which allows customers to cancel orders with limited advance notice to us prior to shipment, and with little or no penalty, we believe that backlog as of any particular date may not be a reliable indicator of our future revenue levels. The cancellation or deferral of product orders, the return of previously sold

products, or overproduction due to a change in anticipated order volume could result in a reduction in revenue and us holding excess or obsolete inventory, which could result in inventory write-downs and, in turn, could have a material adverse effect on our financial condition.

Government Regulations

We are subject to international, federal, state, and local legislation, regulations, and other requirements relating to the discharge of substances into the environment; the treatment, transport, and disposal of hazardous wastes; recycling and product packaging; worker health and safety; and other activities affecting the environment, our workforce, and the management of our manufacturing operations. In addition, most of our customers have mandated that our operations and our products comply with various sustainability initiatives and workers’ rights initiatives initiated by such customers, industry groups in which such customers participate, or the jurisdictions in which such customers operate. We believe that our operations and facilities comply in all material respects with applicable environmental laws and worker health and safety laws. Our efforts to comply with environmental laws and worker health and safety laws could have material impacts on our capital expenditures, competitive position, or financial condition, though the magnitude and duration of such impacts are uncertain and difficult to quantify.

We are also subject to import/export controls, tariffs, and other trade-related regulations and restrictions in the countries in which we have operations or otherwise do business. These controls, tariffs, regulations, and restrictions (including those discussed below in Item 1A, Risk Factors) have had, and we believe may continue to have, a material impact on our business, including our ability to sell products and to manufacture or source components.

Government regulations are subject to change in the future, and accordingly we are unable to assess the possible effect of compliance with future requirements or whether our compliance with such regulations will materially impact our business, results of operations, or financial condition.

Seasonality

Sales of our products are subject to seasonal fluctuation and periods of increased demand in end-user consumer applications, such as smartphones and tablet computing devices. The highest demand for our products generally occurs in our first fiscal quarter ending in December and the fourth fiscal quarter ending in September. The lowest demand for our products generally occurs in our second fiscal quarter ending in March and the third fiscal quarter ending in June.

Employees

Our workforce consists of approximately 10,000 employees located around the world, more than 99% of whom are full-time employees. As of October 3, 2025:

•Our workforce was distributed geographically approximately as follows: 54% in Mexico, 24% in the United States, 20% in Asia, 1% in Canada, and less than 1% in Europe.

•Our workforce was distributed by function approximately as follows: 39% in individual contributor manufacturing roles, 36% in engineering or technician roles, 12% in managerial roles, and 13% in professional or other administrative roles.

•Approximately 3,260 of our employees in Mexico, 550 of our employees in Singapore, and 460 of our employees in Japan were covered by collective bargaining and other union agreements.

We focus on attracting and retaining employees by providing compensation and benefits packages that are competitive within the applicable market for each position. Nearly all full-time employees across the globe are eligible to participate in one of the Company’s incentive plans, under which payments are tied to pre-established performance goals, as well as to purchase shares of the Company’s common stock at a discount from its market price pursuant to the Company’s employee stock purchase plans. In addition, we believe that developing our employees’ skill sets and decision-making abilities—through challenging project assignments, formal training, mentorship, and recognition—is key not only to our employees’ job satisfaction and our retention efforts, but also to maintaining a strong leadership pipeline.
