### What changes On 26 March 2025, Siemens announces it has completed the acquisition of **Altair Engineering**, a vendor of industrial simulation and analysis software, for an **enterprise value of about $10 billion**. The deal, announced on 30 October 2024, makes Siemens a leading simulation player alongside its design (NX), PLM (Teamcenter) and automation offerings. ### Key facts - Price announced on 30 October 2024: **$113 per share**, a 19% premium to the unaffected closing price of 21 October 2024. - New capabilities: mechanical and electromagnetic simulation, high-performance computing (HPC), data science and AI. - Integration into the Siemens Xcelerator platform; Siemens claims "the world's most complete AI-powered portfolio of industrial software" (vendor wording). - Deal presented as a cornerstone of the ONE Tech Company program, meant to raise the group's digital revenue share. ### Why it matters For design offices, simulation becomes a native building block of the Siemens digital twin, from product to plant. The acquisition belongs to a consolidation wave: Synopsys acquires Ansys (July 2025), Cadence takes over Hexagon's design business (February 2026). Choosing simulation tools also means choosing an ecosystem. ### Takeaway One of Siemens' largest software acquisitions, anchoring simulation at the heart of its industrial AI strategy.
