About Altair Engineering Inc.

Altair Engineering Inc. (ticker: ALTR) is a U.S.-based industrial software company that was listed on the NASDAQ in the United States. Founded in 1985 and originally rooted in the Detroit area, Altair has evolved into a recognized provider of engineering software, computational intelligence, and high-performance computing (HPC) solutions. Its long-term positioning sits at the intersection of enterprise software, AI, and computer-aided engineering, with a value proposition centered on accelerating product development, improving design quality, reducing development costs, and helping customers make better technical and business decisions. ([investor.altair.com](https://investor.altair.com/news-releases/news-release-details/altair-signs-definitive-agreement-siemens-be-acquired-106?utm_source=openai)) The company’s portfolio spans several connected domains: multiphysics simulation, data analytics, artificial intelligence, HPC, optimization, and engineering data management. A key commercial platform is Altair One, the company’s cloud gateway, which provides collaborative access to simulation tools and scalable cloud/HPC resources. Altair also uses its Altair Units licensing model, which gives customers flexible access to the broader product suite and supports cross-selling across engineering, analytics, and compute workloads. ([altair.com](https://altair.com/company/?utm_source=openai)) From a competitive standpoint, Altair stands out for its simulation-driven approach and for combining physics-based modeling with data science and cloud delivery. The company serves a broad set of end markets, including automotive, aerospace, manufacturing, electronics, energy, and utilities. Its international footprint is meaningful, with customers and operations across multiple regions, which supports diversification but also exposes the business to industrial capital spending cycles and enterprise software budget decisions. ([altair.com](https://altair.com/company/?utm_source=openai)) Altair has also expanded through targeted acquisitions to deepen its technology stack and broaden use cases. Recent transactions have strengthened areas such as materials data, electronic design automation, and power electronics simulation. The most important recent corporate event was Siemens’ acquisition agreement announced in 2024, approved by Altair shareholders in January 2025, and completed on March 26, 2025, according to an SEC Form 4 filing that states the company was acquired by Siemens Industry Software Inc. ([investor.altair.com](https://investor.altair.com/news-releases/news-release-details/altair-signs-definitive-agreement-siemens-be-acquired-106?utm_source=openai)) For French-speaking investors in Europe, Altair is best viewed as a specialized software asset tied to secular themes such as industrial digitalization, AI-assisted engineering, and HPC adoption. The investment case is therefore fundamentally linked to high-value enterprise software demand, but it must now be assessed in the context of the 2025 change of control, which materially altered Altair’s status as an independent listed company.
