Siemens acquires Altair: New Names, Same Technology, Greater Value for Innovation

Siemens’ acquisition of Altair marks a major strategic step in the digital engineering landscape. The move significantly strengthens Siemens’ global portfolio of simulation, high-performance computing (HPC), artificial intelligence, and digital engineering solutions by consolidating complementary technologies and expertise into an even more integrated ecosystem.

The objective is clear: expand and enhance Siemens’ innovation platform with more connected, scalable, and multidisciplinary tools covering the entire product lifecycle.

What changes for customers?

The main update concerns the rebranding of Altair software, which has now been progressively integrated into the Siemens portfolio and aligned with the new Siemens categorization structure.

It is important to emphasize that:

• Functionalities remain unchanged
• Core technologies are the same
• Workflows remain identical
• Full compatibility with existing models and projects is ensured

Customers can continue using the tools they know and trust, while benefiting from a broader and more integrated ecosystem. In short: the names change, the functionality does not.
