Siemens acquires Altair

Siemens acquires Altair: new names, same technology, greater value for innovation

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

The objective is clear: to expand and enhance Siemens’ platform for industrial innovation by offering increasingly connected, scalable, and multidisciplinary tools across the entire product lifecycle.

What changes for customers?

The main update concerns the rebranding of Altair software, which is now progressively being integrated into the Siemens portfolio and realigned with a new categorization structure.

It is important to highlight that:

• Functionalities remain unchanged
• Core technologies do not change
• Workflows remain the same
• Full compatibility with existing models and projects is guaranteed

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

• A unified environment for industrial digitalization

This combination of expertise now covers the entire product lifecycle: from concept and design to validation and operational optimization.

Operational continuity and new opportunities

For Altair customers, the acquisition represents technological and operational continuity, with the added benefit of access to a broader and more structured ecosystem.

For Siemens customers, it means access to an even more comprehensive portfolio capable of integrating simulation, AI, data management, and HPC in a consistent and synergistic way.

The technology remains the same. The value increases.
