Designed to manage both central and space HVAC systems, the platform also offers hybrid system control through IR, and incorporates nevo®.ai for device onboarding, remote control and embedded support, delivering enhanced intelligence, energy management and ease of use across customer-specific deployments.

During 2025, our development teams successfully completed and released new products in the connected home space for customers such as Daikin, Carrier, Mitsubishi, Somfy, SimpliSafe, and Vivint.

During 2025, our advanced engineering efforts focused on further developing our existing products, services and technologies. We released a host of unique QuickSet Cloud features such as QuickSet homeSense for occupancy and presence detection, video and audio content and app history, and support for Thread, as well as continued development initiatives around existing and emerging technologies, such as Zigbee 3.0, Bluetooth Smart, WiFi and Matter, a unifying, IP-based connectivity protocol built on proven technologies designed to connect smart home devices reliably and securely across disparate IoT ecosystems.

Because of the nature of R&D activities, there can be no assurance that any of our R&D projects will be successfully completed or ultimately achieve commercial success.

Intellectual Property and Technology

A key factor in our ability to deliver advanced home entertainment, climate control and smart home solutions is our proprietary device knowledge libraries and discovery technologies. These libraries—which support IR, HDMI CEC, Bluetooth, Zigbee (Rf4CE), Z Wave, Thread, Matter and IP based protocols—continue to expand each year and form the foundation for our setup, identification and control capabilities across a broad range of devices.

Our HVAC engine provides the logic and sequence control required for efficient operation of heating and cooling systems, including heat pumps and single, dual, and multi fuel HVAC equipment. We also maintain proprietary bi-directional communication protocols used by leading HVAC OEMs to enable optimized control and access to diagnostic system data.

We integrate our software and control libraries into the integrated circuits we ship to manufacturers, and we also license these technologies directly to OEMs and service providers. Our solutions extend to home entertainment and home automation products through wired CEC and wireless IP protocols that automatically detect, identify and configure supported devices. These libraries are continuously updated using data sourced directly from original devices and manufacturer specifications.

We maintain a broad portfolio of patents covering our discovery, setup and control technologies across climate control, safety and security, and smart home automation applications. Our patents have remaining lives ranging from less than one year to 18 years. We also hold copyrights on proprietary software and device control libraries and maintain registered trademarks for many of our product names in the United States and internationally. In certain cases, we rely on common law trade secret protection when appropriate.

Manufacturing and Supply

We are vertically integrated across design, development, and manufacturing. Our manufacturing capabilities include high-quality surface mount technology, zero-gap, plastic injection, acoustic design, painting, keypad, robot soldering, and laser etching. We currently operate manufacturing and assembly factories in the PRC, Vietnam and Brazil, which allows us to produce in the regional markets. We also use selected third-party manufacturers and suppliers in Asia and Mexico.

Our long-term factory planning strategy is to reduce our reliance on any single region and, in some cases, transition away from vertical integration and associated fixed costs, by (1) reducing our manufacturing concentration in the PRC, (2) pursuing lower cost jurisdictions for manufacturing to help ensure market competitive products and (3) offering customers a flexible and globally diverse manufacturing footprint to provide a reliable and cost-efficient supply chain. As part of the execution of this strategy, we (1) opened a new factory in Vietnam, which commenced operations in June 2023, (2) stopped production activities in our southwestern PRC factory in the third quarter 2023 and completed its shutdown in the first quarter 2024, (3) stopped production activities and shutdown operations of our smaller eastern PRC factory during the fourth quarter 2024 and (4) discontinued our Mexico operations in 2025. We continue to evaluate our global factory footprint to identify ways to operate more efficiently.

With regard to the potential for recent tariff activities related to our products sourced globally, our global supply chain team is actively monitoring, reviewing and assessing any potential impact to our products and supply chain across the world. We have strategically developed a global manufacturing footprint to enhance efficiency and mitigate risks associated with international trade policies to better serve our global customer base.

Even though we operate one factory in the PRC, one factory in Vietnam and a manufacturing and assembly plant in Brazil, respectively, we continue to evaluate additional third-party manufacturers and sources of supply. During 2025, we utilized multiple third-party manufacturers and maintained duplicate tooling for certain products. Where possible, we utilize standard parts and components, which are available from multiple sources.

We are a large consumer of integrated circuits, including low-power, RF chips and modules that are used throughout our products. We continually seek additional sources to reduce our dependence on our integrated circuit suppliers. To further manage our integrated system on a chip supplier dependence, we include microcontroller technology which incorporates non-volatile, reprogrammable flash memory in most of our products. Flash memory-based microcontrollers have shorter lead times than microcontrollers using other memory technologies and may be reprogrammed. This allows us flexibility to use a given component on many different products, has the added benefit of potentially reducing excess and obsolete inventory exposure and allows us to update our product functionality in the field. This diversification lessens our dependence on any one supplier and allows us to negotiate more favorable terms. We had one supplier, Qorvo, that represented 10.2% of our inventory purchases in 2025. We did not have any suppliers that represented over 10% of our inventory purchases in 2024 or 2023.

Our manufacturing process consists of plastic injection molding, keypad molding, coating or painting, surface mount technology, assembly, software programming, functional testing, packaging, and quality control. We conduct operations utilizing a formal, documented quality management system to ensure that our products and services satisfy customer needs and expectations. Our manufacturing facilities are certified to the ISO 9001:2015 International Standard for quality management. Testing and quality control are applied to components, parts, sub-assemblies and systems obtained from third-party suppliers. Our manufacturing facility in Yangzhou, PRC is certified to the TL 9000 Standard, which is the telecom industry's unique

extension to ISO 9001:2015. All of our manufacturing facilities are certified to the ISO 14001:2015 International Standard for environmental management systems. In addition, our manufacturing facilities in Vietnam and Yangzhou, PRC have also achieved ISO 45001 International Standard for safety and health management systems.

We are focused on reducing the environmental impact of our operations. Our manufacturing facility in Yangzhou, PRC hosts an on-site solar renewable energy system, and we are evaluating the use of renewable energy in other locations. Our teams continue to examine practices and processes throughout our facilities to identify opportunities for greater energy efficiency. Each of our manufacturing facilities has standing policies and targets for the monitoring and management of waste generation and energy consumption and is focused on reducing electricity consumption, water usage and greenhouse gas emissions. In April 2024, we signed our Commitment Letter to the Science Based Targets Initiative ("SBTi"), showcasing our dedication to establishing an approved science based target for reducing greenhouse gas emissions.

We are committed to complying with applicable labor laws and regulations of the countries in which we operate and supporting ethical labor practices that do not infringe on human rights. We are a regular member of the Responsible Business Alliance ("RBA"), an industry coalition dedicated to driving sustainable value for workers in global supply chains, among other things. As a regular member of the RBA, we have adopted the RBA Code of Conduct, which establishes standards to ensure that working conditions are safe, that employees are treated with respect and dignity and that business operations are environmentally responsible and conducted ethically. The RBA Code of Conduct has been reflected in our employee policies and procedures. We conduct regular internal audits in line with RBA, have engaged in third-party Sedex Members Ethical Trade Audits ("SMETA") and RBA audits in our factories and regularly monitor ethics-related key performance indicators. In July 2024, our manufacturing facility in Vietnam successfully completed the RBA Validated Assessment Program ("VAP") audit, achieving a Silver VAP Recognition Level.

Our third party due diligence program and ethics and sustainability management systems are aligned with internationally recognized labor and human rights standards, including the RBA Code of Conduct. This includes evaluating and addressing human rights concerns in our supply chain. We follow RBA guidelines for the supplier risk assessment process. We utilize a combination of third party due diligence platforms and RBA management systems to screen all suppliers for sustainability and ethics concerns. Suppliers are evaluated based on key risk indicators to determine the level of due diligence required. Based on assessed risk, certain suppliers are subject to on‑site audits conducted by UEI auditors or approved third party auditors. High risk suppliers are required to complete an onsite RBA VAP audit. We require suppliers to adhere to our Global Supplier Code of Conduct ("Supplier Code of Conduct"), which is available on our website. Our Supplier Code of Conduct sets forth our global expectations in the areas of fair dealing, legal compliance, business integrity, labor practices, health and safety and environmental management. Among other things, we require our suppliers to respect human rights and to not engage in any form of involuntary or forced labor and to fully comply with all laws and regulations pertaining to the appropriate and dignified treatment of all workers.

Our Global Human Rights Policy is aligned with internationally recognized human rights principles defined by the Universal Declaration of Human Rights and the United Nations Guiding Principles on Business and Human Rights. We provide training to all employees to help identify and report any signs of forced labor or other unlawful labor practices. We have a third-party confidential ethics hotline ("the UEI Ethics Line") to enable our employees or other stakeholders to anonymously report any suspected violations of applicable laws, policies or human rights violations. We are committed to investigating all communications received on the UEI Ethics Line.

Government Regulation and Environmental Matters

Many of our products are subject to various federal, state, local and international laws governing chemical substances in products, including laws regulating the manufacturing and distribution of chemical substances and laws restricting the presence of certain substances in electronics products. We may incur substantial costs, including cleanup costs, fines and civil or criminal sanctions, third-party damages, or personal injury claims, if we were to violate or become liable under environmental laws or if our products become non-compliant with environmental laws. We also face increasing complexity in our product design and procurement operations as we adjust to new and future requirements relating to the material composition of our products.

We may also face significant costs and liabilities in connection with product take-back and "right to repair" legislation both in the U.S. and abroad. For example, the European Union's Waste Electrical and Electronic Equipment ("WEEE") Directive makes producers of electrical goods financially responsible for specified collection, recycling, treatment, and disposal of past and future covered products. Our European subsidiaries are WEEE compliant.

We believe that we have materially complied with all currently existing international and domestic federal, state and local statutes and regulations regarding environmental standards and occupational safety and health matters to which we are subject.

During the years ended December 31, 2025, 2024 and 2023, the costs incurred in complying with federal, state, local and foreign statutes and regulations pertaining to environmental standards and occupational safety and health laws and regulations did not materially affect our earnings, financial condition or competitive position. In addition, during the same period, the costs incurred in complying with other applicable government regulations likewise did not materially affect our earnings, financial condition or competitive position. However, due to the heightened awareness of corporate sustainability, human capital and governance matters and evolving laws and regulations or enforcement policies, increases in compliance costs may have a material adverse effect upon our capital expenditures, earnings or financial condition.

We are committed to reducing and eliminating substances of concern from our products and manufacturing process. Our products distributed in the European Union are compliant with the RoHS (Restriction of Hazardous Substances Directive 2011/65/EU and 2015/863/EU) and REACH (Registration, Evaluation, Authorization and Restriction of Chemicals) directives. In other regions, we also need to comply with our customers' specific requirements relating to the non-use of certain hazardous substances in the products, which are typically equally or more stringent than the RoHS directive. We have a dedicated "Green Team" comprised of engineers and environmental regulation experts, that analyze our products, processes, and raw materials to help ensure that we comply with environmental and government regulations worldwide, as well as the applicable "Green" requirements imposed by our customers. Our factories are certified to the Environmental Management System ISO 14001:2015 standard. Additionally, we have in-house testing capability to help ensure product compliance. We place great importance on compliance to local health and safety laws and regulations. At our manufacturing facilities, we are also committed to protecting our workers from exposure to hazardous substances following the principles established for the health and safety management system, ISO 45001. For example, we have replaced volatile organic compounds ("VOC") emitting inks and paints with reduced-VOC paints at some of our manufacturing facilities.

We strive to extend the useful life of our products and reduce our products' impact on the environment. We have invested in R&D to improve the energy efficiency of our battery-operated products. For example, we deploy a low energy IR-engine in some of our products, which can extend battery life regardless of the protocols utilized by the product. We have introduced our control platform and related technologies that address the growing demand for sustainable products that reduce energy use and eliminate waste. With this platform, we partnered with technology leaders and invested in bringing ultra-low power connectivity chips with built-in energy harvesting and photovoltaic cells to the market. These chips offer more computing power while consuming substantially less battery power. In addition, to reduce energy consumption even further, we have introduced solutions powered by low-light solar cells for the entertainment remote control and IoT markets.

We also offer a product refurbishment program to our customers where we reclaim, refurbish and recycle pre-owned remote controls. Under this program, major components in pre-owned remote control units are reused or recycled. For example, the printed circuit board assemblies ("PCBA") are cleaned, tested and reused, or plastics are reground to be reused. We have also employed new master carton packing methods to increase shipping efficiency and reduce cardboard usage. Some of our manufacturing facilities are switching to the use of recycled solder. To further reduce collateral waste, we have introduced an initiative to reduce and/or remove single use plastics ("SUP") from our supply chain and manufacturing process for certain customer programs.

In the nations where we have operations or otherwise conduct business, we are also subject to tariffs, import/export controls, and other trade-related laws and limitations. These limits, regulations, and tariffs, especially those pertaining to or affecting relations between the United States and the PRC, might significantly disrupt our business, affecting our capacity to manufacture, source components and sell goods. The current U.S. administration has introduced new policies imposing additional tariffs on goods manufactured abroad, including goods manufactured in the PRC, Brazil, Vietnam and Mexico. Tariffs imposed under the International Economic Emergency Powers Act on the PRC and Mexico were declared unlawful by the U.S. Supreme Court on February 20, 2026, and have since been lifted, but the Administration has moved to replace them with new duties under alternative authorities, including Section 122 of the Trade Act. Significant uncertainty continues to exist about the future of U.S. trade policy and the implementation of new tariffs, including but not limited to, new tariffs on goods manufactured in the PRC and Mexico. This includes the 2026 Joint Review of the U.S.-Canada-Mexico Agreement (“USMCA”), which could impact rules of origin and import restrictions on trade with Mexico. These measures, if fully implemented, will increase costs for certain goods imported into the United States.

Climate Change

Our operations, supply chain and products are expected to become increasingly subject to federal, state, local and foreign laws, regulations, and international treaties relating to climate change, such as climate disclosure, carbon pricing or product energy efficiency requirements. We have established an executive-level Environmental Working Group to further integrate environmental considerations throughout the product lifecycle, ensure compliance with environmental regulations and customer requirements, implement sustainable practices in our operations, reduce our product's environmental footprint, and deliver more

cost-effective and lower carbon technology solutions to our customers. We believe that technology will be fundamental to finding solutions to achieve compliance with and manage those requirements. Our Board of Directors (the "Board"), specifically the Corporate Governance, Sustainability and Nominating Committee, is responsible for risk oversight, which includes relevant environmental-related risks such as climate change.

Government regulations are subject to change; therefore, we are unable to predict the impact of complying with potential future requirements or whether doing so will materially affect our operations, financial situation or business.

Human Capital

As of December 31, 2025, we employed 3,099 members of staff across our worldwide facilities. Of this staff, 2,392 are associated with our manufacturing and supply chain organizations in the PRC, Vietnam, Mexico and Brazil. Beyond the manufacturing and supply chain organizations, 390 of our staff work in engineering and R&D, 96 in sales, marketing, consumer service and support and 221 in executive and administrative functions.

Additionally, in the PRC, we work with third-party agencies who have recruited and provided us with a small percentage of our workers to support our production activities. These third-party agencies have been required to adhere to both the relevant RBA Code of Conduct requirements and our own Supplier Code of Conduct, which among other things, prohibits the use of forced labor and sets forth requirements on fair dealing, legal compliance, business integrity, labor practices, health and safety and environmental management. We have also standardized the qualification, contract and monitoring standards for all third-party agencies.

We intend to post on that website any future changes or amendments to our Code of Conduct, and any waiver of our Code of Conduct that applies to any of our executive officers or a member of our Board within four business days following the date of the amendment or waiver.

Labor unions represent approximately 6.0% of our 3,099 employees as of December 31, 2025. Some of these unionized workers are employed in Monterrey, Mexico, and are represented under contract with the Sindicato Industrial de Trabajadores de Nuevo León adherido a la Federación Nacional de Sindicatos Independientes. Unionized workers, employed in Manaus, Brazil, are represented under contract with the Sindicato dos Trabalhadores nas Industrias Metalugicas, Mecanicas e de Materiais Eletricos de Manaus. Additionally, workers at our Vietnam facility are covered by a collective bargaining agreement. These workers represent approximately 20.0% of our 3,099 employees as of December 31, 2025. Our business units are subject to various laws and regulations relating to their relationships with their employees. These laws and regulations are specific to the location of each business unit. We believe that our relationships with employees and their representative organizations are good.

Safety, Health and Wellness

The health and safety of our employees, contractors, visitors and the communities in which we operate is paramount. We are committed to reducing or eliminating health and safety risks through our health and safety programs, including effective control measures, emergency response plans and training programs. We continually monitor and evaluate health and safety performance against established goals and industry standards and maintain clear procedures for collecting information about health and safety incidents, near misses, and concerns. Each incident is thoroughly investigated, and corrective actions are taken to prevent their recurrence. These metrics are communicated to leadership through regular management reviews. This commitment is outlined in our global health and safety policy. As a member of RBA, we also adhere to the standards of the RBA Code of Conduct to ensure working conditions are safe throughout our supply chain.
