Background

In today's era of pervasive intelligence, we have seen an acceleration in innovation cycles and a growing opportunity for Synopsys. The proliferation of silicon to power our digital world, where technology is omnipresent and interconnected, means computing is being reinvented with the rise of AI and software-defined systems. In turn, this is driving an increase in the activity of new and existing chip and system design companies around the world.

These developments are accompanied by increasing complexity. It is now common for a single chip to combine many components (processor, communications, memory, custom logic, input/output) and embedded software into a single system-on-chip (SoC), requiring highly complex chip designs. The most complex chips today contain more

than a billion transistors. Transistors are the basic building blocks for ICs, each of which may have features that are less than 1/1,000th the diameter of a human hair.

These devices are manufactured using masks to direct beams of light onto a wafer of silicon. At such small dimensions, the wavelength of light itself can become an obstacle to production, proving too big to create such dense features and requiring creative and complicated new approaches. Designers have turned to new manufacturing techniques to solve these problems, such as multiple-patterning lithography, FinFET 3D transistors and Gate-All-Around Field-Effect transistor structures, which in turn have introduced new challenges to design and production.

The rise of silicon-powered intelligent devices and AI has increased demand for chips and systems with greater functionality and performance, reduced size and lower power consumption. Our customers, who design silicon and software-defined systems, are facing intense pressure to deliver innovative offerings in shorter timeframes and at lower prices. In other words, innovation in chip and systems design often hinges on providing products "better," "sooner," and "cheaper" than competitors. The design of these chips and systems is extremely complex and demands engineering solutions with a deeper integration of electronics and physics, enhanced by AI. Over the past several years, market verticals including AI, 5G, automotive and cloud computing infrastructure have contributed to the ongoing demand for our products and services. With ANSYS, Inc, (Ansys) now part of Synopsys, we can maximize the capabilities of product R&D teams broadly enabling them to rapidly innovate AI-powered products.

Our Role-As the Silicon to Systems Engineering Solutions Partner

Synopsys' silicon to systems engineering solutions are designed to help our customers-chip and system engineers and software developers-speed up time to market, achieve the highest quality of results, mitigate risk, and maximize profitability.

Chip and systems designers must determine how best to design, locate and connect the building blocks of intelligent systems, and to verify that the resulting design behaves as intended and can be manufactured efficiently and cost-effectively. This is a complex, multi-step process that is expensive and time-consuming. Our wide range of products help at different steps in the overall design process, from the design of individual ICs to the design and simulation of larger systems. Our EDA products increase designer productivity and efficiency by automating tasks, keeping track of large amounts of data, adding intelligence to the design process, facilitating reuse of past designs and reducing errors. Our S&A products give engineers the ability to explore and predict how products will work in the real world, helping them speed time-to-market, lower manufacturing costs, improve quality, and decrease risk. Our silicon IP products offer proven, high-quality pre-configured circuits that are ready to use in a chip design, saving customers time and enabling them to direct resources to features that differentiate their products. Our global service and support engineers provide expert technical support and design assistance to our customers.

Our commitment to health, safety, and wellness is underscored by resources that help employees thrive in a hybrid work environment and balance work and personal life. Our Synopsys Wellbeing campaign encourages leaders and managers to model healthy behaviors and create opportunities for team wellness activities. We also offer a variety of programs and resources at no cost to employees and their families to support their mental, emotional, and financial well-being.

Employee Engagement

We maintain a comprehensive employee feedback program to understand the employee experience and make improvements in areas such as customer interaction and knowledge sharing. Through our annual SHAPE Synopsys survey, we gather employee insights on values, manager effectiveness, innovation, belonging, and other critical factors. We also use pulse surveys to provide space for conversations about identity, direction, and connection.

In October 2025, approximately 95% of our employees participated in the SHAPE survey. We received an engagement score of 81, which was calculated by averaging favorable responses to job satisfaction questions. In fiscal 2025, Synopsys received more than 90 workplace and culture awards, including Great Place to Work certification in 14 countries and recognition from Newsweek, Forbes, Fortune, U.S. News & World Report, Comparably, and The Wall Street Journal. These results demonstrate Synopsys' stability and resiliency and the fact that we have a highly engaged global workforce. Employees reported strong excitement for the company's future, trust in leadership, a sense of belonging, and personal investment in our mission.

To promote employee engagement and recognition, we invest in programs such as the annual Engineering and Innovation Conference and Pitch Fest innovation contest. As we grow, we aspire to maintain our results-oriented

culture by balancing productivity with smart investments in our employees' development, while also supporting individual well-being. These are two key drivers of the overall employee experience.

We believe strong individual and business performance stems from engaged employees who have clarity on goals, receive regular feedback, and have opportunities to grow. Building on our commitment to development, our enhanced performance process deepens the connection between individual objectives and key results, our values, and overall company outcomes. This is an agile performance process that drives transparency through continuous feedback and quarterly goal alignment conversations. These efforts are supported by the implementation of a new AI-powered performance management platform.

Talent Development and Succession Planning

We offer programs to support career advancement, including a digital learning platform that fosters a "curious learning" culture with access to training, articles, videos, and blogs. We also host in-person and on-demand learning sessions designed to build capabilities and adaptability required for the future. As employees advance in their careers, our training framework is intended to develop new technical skills and core competencies.

Our management training focuses on communication, engagement, coaching, hiring, and key business skills. This is based on our belief that employees should work for and with great managers and leaders. The training aims to promote an ethical and supportive work environment that is free from bias and harassment. In fiscal 2025, we introduced courses to help managers lead through change and become effective coaches. Regions and business teams also customize development programs for their specific demographics.
