Integrating Altair's capabilities in the areas of simulation, HPC, data science, and AI enhances the ability of Siemens to drive more efficient and sustainable products and processes. Now, all Siemens customers, from engineers to generalists, will have access to new simulation expertise, can optimize their high-performance computing processes, create new AI tools and perform data analytics to help accelerate innovation and digital transformation for companies of all sizes.  

The acquisition of Altair is part of Siemens' ONE Tech Company program and will meaningfully increase Siemens' digital revenue share. This growth program enables Siemens to further expand its strong market position and reach the next level of performance and value creation.
