Several financial platforms continue to display what appears to be live trading data and analyst projections for Altair Engineering, despite the software developer ceasing to exist as a publicly traded entity following its acquisition by Siemens.
The Acquisition and Its Aftermath
Siemens Industry Software Inc. completed its all-cash purchase of Altair Engineering in March 2025. Shareholders received $113 per share in the transaction. Trading of the stock was halted on March 26, 2025, with its official delisting from public markets occurring the following day.
However, numerous financial websites persist in showing seemingly current information, including:
* Quoted share prices fluctuating around $111.75 to $111.85
* Active analyst ratings and consensus forecasts
* Price targets set for September 2025 and later periods
This data is obsolete and does not represent the company’s current status as a privately held subsidiary within the Siemens organization.
Should investors sell immediately? Or is it worth buying Altair Engineering?
Strategic Rationale Behind the Siemens Deal
The acquisition significantly bolsters Siemens’ industrial software offerings, particularly in the fields of artificial intelligence, simulation, and high-performance computing. Plans are in place to integrate Altair’s technology into Siemens’ Xcelerator platform to accelerate developments in digital twins and sustainability transformations.
The former Altair team continues its development work under Siemens, having recently launched the HyperWorks 2025 platform in February 2025, which emphasizes AI-driven engineering solutions.
Implications for the Investing Public
For individual investors, Altair Engineering shares are no longer a tradable security. The company does not issue independent quarterly earnings reports, and analyst coverage or technical indicators for its standalone performance are no longer relevant. All financial results are now consolidated into Siemens’ broader corporate reporting.
Investors encountering real-time price quotes for ALTR should treat them as historical artifacts. For accurate and current information, consulting official communications from Siemens is essential.
