Autodesk Stock Sinks on Report Firm Is Looking To Buy Rival Software Maker PTC

Autodesk (ADSK) was among the worst-performing stocks in the S&P 500 Thursday, a day after a report that the engineering-software company was mulling an acquisition of rival PTC (PTC).

Citing people familiar with the matter, Bloomberg reported Wednesday that Autodesk “has been working with advisers to evaluate a cash-and-stock deal for Boston-based PTC.” The news site added that “no final decision has been made and Autodesk could opt against pursuing a deal for PTC.”

Autodesk has a market capitalization of about $60 billion, while PTC has a market value of roughly $23 billion.

Neither Autodesk nor PTC immediately returned an Investopedia request for comment.

Autodesk shares sank 7% in recent trading to move into negative territory for the year. PTC shares were down nearly 6% but remain up almost 8% for 2025.
