Description of Business	Description of Business Synopsys, Inc. (Synopsys, we, our or us) provides products and services used across the entire Silicon to Software spectrum to bring Smart Everything to life. From engineers creating advanced semiconductors to product teams developing advanced electronic systems, our customers trust that our technologies will enable them to meet new requirements for energy efficiency, reliability, mobility, security and more. We are a global leader in supplying the electronic design automation (EDA) software that engineers use to design and test integrated circuits (ICs), also known as chips or silicon. We provide software and hardware used to validate the electronic systems that incorporate chips and the software that runs on them, including cloud-based digital design flow to boost chip-design development productivity. We also provide technical services and support to help our customers develop advanced chips and electronic systems. These products and services are part of our Design Automation segment. We also offer a broad and comprehensive portfolio of semiconductor intellectual property (IP) products, which are pre-designed circuits that engineers use as components of larger chip designs rather than designing those circuits themselves. These products and services are part of our Design IP segment. We are also a leading provider of software tools and services that improve the security, quality and compliance of software in a wide variety of industries, including electronics, financial services, automotive, medicine, energy and industrials. These tools and services are part of our Software Integrity business. On May 5, 2024, we entered into an Equity Purchase Agreement (the Purchase Agreement) by and between Synopsys and Sapphire Software Buyer, Inc. (Buyer), an entity controlled by funds affiliated with Clearlake Capital Group, L.P. and Francisco Partners (together, the Sponsors), pursuant to which we will sell our Software Integrity business.
