Autodesk Inc. is no longer pursuing an acquisition of Boston-based PTC Inc., people familiar with the matter said, which would have ranked as one of the year’s largest deals. The software provider has decided to shelve its work on a potential cash-and-stock deal for PTC,

Shares of Autodesk climbed 5.6% to $296.14, while PTC stock declined 1.7% to $190.27. PTC didn’t immediately respond to a request for comment from Barron’s. An Autodesk spokesperson directed Barron’s to the SEC filing, saying it contained the company’s “full statement” on the matter.

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