Business Strategy

We believe our long-term success depends on improving operational performance, optimizing capital allocation, and returning to growth.

Improving operational performance

We have achieved our current cost position through development of manufacturing scale and efficiencies, a continual process of migration and transformation to best-cost manufacturing locations, global best-cost sourcing, product design improvements, and ongoing productivity-enhancing initiatives. We also use our decades of manufacturing expertise to drive efficient, high-quality processes. We leverage next-generation automation to lower labor costs and to drive towards zero defects. We are building resilient supply chains with a balanced approach in ensuring the continuity of supply while aggressively focusing on innovative ways to drive material cost down. Through collaboration and partnership across our project teams, sourcing, and our supply base partners, we have identified and are executing on project-based material savings programs to help mitigate inflation. In addition, we continue to drive operational efficiencies with network analysis and optimization, lean initiatives, and accelerating automation deployments to mitigate both labor shortages and wage inflation pressures in our factories.

Optimizing capital allocation

Our capital allocation strategy is primarily focused on supporting the growth of the business through capital expenditures, maintaining our dividend, reducing our debt levels, and repurchasing shares opportunistically.

•In September 2023, our Board of Directors authorized a new $500.0 million ordinary share repurchase program (the “September 2023 Program”), effective on October 1, 2023. In the twelve months ended December 31, 2025, we paid $120.6 million to repurchase shares and $70.4 million in cash dividends.

Returning to growth

While we may continue to consider strategic partnerships and acquisitions to accelerate the growth and transformation of our product portfolio and to obtain access to new technologies, expertise, processes, and solutions, our primary focus is growing the core business, which continues to have meaningful end market demand and generate strong cash flows. Our future success builds upon our deep expertise in customizing the base technologies developed over the years, improving them meaningfully over time, and expanding to other end markets or applications. In some cases, we look to accelerate this by integrating new technologies and capabilities that have been acquired.

Automotive

The Automotive reportable segment accounted for approximately 57.0% of our net revenue in fiscal year 2025. It primarily serves the Automotive OEM and aftermarket industries through the development and manufacturing of sensors, high-voltage solutions (i.e., electrical protection components), and other solutions that are used in mission-critical systems and applications.

Our solutions are present in a wide variety of transportation systems and subsystems, playing a critical role in ensuring the functionality and safety of a vehicle’s operation. Within both internal combustion and electrified propulsion architectures, we provide various sensor solutions (e.g., electric motor position, gasoline direct injection, oil pressure monitoring, exhaust temperature, electric motor position, and fuel delivery) that enable superior functionality, efficiency, and optimized performance while reducing environmental impact. As more transportation platforms leverage a plug-in hybrid or fully electrified powertrain, the ability to protect the vehicle systems/sub-systems from high-voltage power sources becomes critical, a need that our electrical protection portfolio (e.g., high-voltage contactors, fuses, and high-voltage junction boxes) addresses. Our cabin thermal management (e.g., pressure plus temperature sensing) and safety (e.g., braking, electronic stability control, and tire management solutions) sensor/product solutions all play critical roles in enabling safety, improved performance, and increased efficiency and range across ICE, plug-in hybrid, and electrified powertrains.

Applications we serve require close engineering collaboration between us and our OEM partners or their Tier 1 suppliers. Solutions are designed to meet application-specific requirements with customer-specific fit, form, and function. As a result, OEMs and Tier 1 suppliers make significant investments in selecting, integrating, and testing sensors as part of their product development. Once our solutions are designed into an application, we are well positioned as the incumbent supplier due to the high degree of sensor customization and application/vehicle platform certification. This results in high switching costs for automotive manufacturers once a sensor is designed into a particular system or platform. We believe this is one of the reasons that sensors are rarely changed during a platform lifecycle, which in the case of the automotive industry typically lasts five to seven years. OEMs and Tier 1 suppliers seek to partner with suppliers with a proven record of quality, on-time delivery, and performance, as well as the engineering and manufacturing scale/resources to meet their needs over the multi-year lifecycle of these highly engineered vehicles and systems.

Markets

The markets we serve are seeking to provide cleaner, safer, and connected solutions. Transportation industries provide some of the largest markets for sensors, giving participants with a presence in these markets significant scale advantages over those participating only in smaller, more niche industrial and medical markets. As electrified transportation platforms continue to evolve and grow, we expect OEM and Tier 1 suppliers to continue to require sensing partners that can meet their increasing needs for mission-critical sensors and solutions, enabling their global vehicle strategies.

We believe light vehicle production is a proxy for automotive end market growth. We believe that growth in the automotive end market has historically been driven by three principal trends: growth in the number of vehicles produced globally and expansion in the number and type of sensors per vehicle.

Table of Contents

Number of sensors per vehicle: We believe that the number of sensors used in vehicles of all classes will continue to be driven by increasing requirements in vehicle emissions, efficiency, safety, electrification, and comfort-related control systems that depend on sensors for proper functioning, such as electronic stability control, tire pressure monitoring, advanced driver assistance, advanced combustion and exhaust after-treatment applications. For example, government regulation of emissions, including fuel economy standards such as the National Highway Traffic Safety Administration’s Corporate Average Fuel Economy requirements in the U.S. and emissions requirements require advanced sensors to achieve these performance metrics. Sensors are crucial enablers for a vehicle’s systems and sub-systems to meet the ever-increasing requirements in a vehicle’s operation.

New Technology: Automobiles continue to evolve, with new alternative technologies being developed to make these vehicles more efficient, reliable, financially viable, and safe. We believe this trend will drive growth in our business for the foreseeable future. Moreover, we believe our broad customer base, global diversification, and evolving portfolio provide the foundation that will allow us to grow with these trends across a diverse set of markets.

Table of Contents

evolving set of customer requirements and new product introductions. We conduct such activities in areas we believe will increase our long-term revenue growth. Our development expense is typically associated with engineering core technology platforms for specific applications and engineering major upgrades that improve functionality or reduce the cost of existing products. Our sustaining engineering expense consists of costs related to modifying existing products for use by new and existing customers in familiar applications, as well as costs to improve our manufacturing processes. We begin many development opportunities at an early stage for several reasons: (1) we are the incumbent in many systems for our key customers; (2) we have robust design and service capabilities; and (3) our global engineering teams are located close to key customers in regional business centers.

We rely primarily on patents, trade secrets, manufacturing know-how, confidentiality procedures, and licensing arrangements to maintain and protect our intellectual property rights. While we consider our patents to be valuable assets, we do not believe that our overall competitive position is dependent on patent protection or that our overall business is dependent upon any single patent or group of related patents. Many of our patents protect specific functionality in our products, and others consist of processes or techniques that result in reduced manufacturing costs.

The following table presents information on our patents and patent applications as of December 31, 2025:

U.S.

Non-U.S.

Patents282 636

Pending patent applications filed within the last five years70 282

Our patents have expiration dates ranging over the next nineteen years through 2045. We also own a portfolio of trademarks and license various patents and trademarks. "Sensata" and our logo are trademarks.

We use licensing arrangements with respect to certain technology provided in our sensor and electrical protection products. In 2006, we entered into a perpetual, royalty-free cross-license agreement with our former owner, Texas Instruments Incorporated, which permits each party to use specified technology owned by the other party in its business. No license may be terminated under the agreement, even in the event of a material breach.

Raw Materials

We use a broad range of manufactured components, subassemblies, and raw materials in the manufacture of our products in all of our segments, including those containing certain commodities (e.g., semiconductors, resins, and metals), which may experience significant volatility in their price and availability due to, among other things: new laws or regulations, including labor laws and the impact of tariffs; trade barriers and disputes; global economic or political events, including government actions and labor strikes; suppliers' allocations to other purchasers; interruptions in production by suppliers; increased logistics costs; changes in foreign currency exchange rates; and prevailing price levels.

Seasonality

Because of the diverse global nature of the markets in which we operate, our net revenue is only moderately impacted by seasonality. Industrials experiences some seasonality, specifically in its air conditioning and refrigeration products, which tend to peak in the first two quarters of the year as inventories are built up for spring and summer sales. In addition, Automotive's net revenue tends to be weaker in the third quarter of the year as automotive OEMs retool production lines for the coming model year.
