What We Know

IronSource went public in June 2021 through a merger with a special purpose acquisition company (SPAC), trading on NYSE under the ticker IS. However, the company's independence was short-lived, as Unity Software announced its intention to acquire IronSource in July 2022 for approximately $4.4 billion in an all-stock deal. The acquisition was completed in November 2022. The Unity-IronSource merger was designed to create a comprehensive platform for mobile app development, monetization, and user acquisition. IronSource now operates as part of Unity's ecosystem, and the stock is no longer traded independently. Unity saw strategic value in combining its game development tools with IronSource's monetization and advertising technology.
