Schneider Electric SE, the French energy-management giant, agreed to buy Boston-based industrial software company PTC Inc. in an all-cash deal worth roughly $22.6 billion in equity value, the companies disclosed in a securities filing made public this week. The deal, inked October 4 and filed with regulators October 5, is one of the largest tech acquisitions announced anywhere so far this year.

Under the agreement, Schneider Electric will pay $205 in cash for every share of PTC — a 42.3% premium over the stock's last closing price and a 46.1% premium to its 30-day average, according to PTC's own disclosures to the SEC. Including debt, the transaction values the company at roughly $23.7 billion. PTC's roughly 108.6 million outstanding shares will convert to cash, and once the deal closes the company's stock will be delisted from the Nasdaq Global Market and PTC will cease to exist as a public company.

PTC, founded in 1985 and known for its Creo design and Windchill product-lifecycle software, moved its global headquarters to Boston's Seaport District in 2019. Schneider Electric, headquartered outside Paris, has spent the past several years buying up industrial-software and AI firms — including Aveva and, earlier this year, the Norwegian industrial-AI company Cognite — to build out what it calls its "digital thread" from factory floor to boardroom.

Why the deal, and why now

Schneider says folding PTC's design and engineering tools into its own energy and automation business roughly triples its addressable software market, particularly in discrete manufacturing, and should generate about €250 million in annual cost savings within three years plus roughly €800 million in additional revenue from cross-selling. The company plans to fund the purchase with a combination of new equity (about €5-6 billion), new debt (about €16-17 billion), and a bridge facility underwritten by Morgan Stanley and Société Générale, per the filing.

"THE ACQUISITION OF PTC REPRESENTS AN IMPORTANT STEP FORWARD IN OUR AMBITION TO LEAD THE NEW ERA OF ENERGY AND INDUSTRIAL INTELLIGENCE."

That's how Schneider Electric CEO Olivier Blum framed the purchase in the companies' joint announcement. PTC President and CEO Neil Barua struck a similarly upbeat tone, saying joining Schneider was "an incredible opportunity to elevate the scope and impact of what we deliver for our customers globally." Both companies' boards have unanimously approved the merger agreement, and PTC's board is recommending shareholders vote yes.

The deal still has hurdles to clear. Because a French buyer is acquiring an American technology company with deep ties to manufacturing and engineering data, the transaction is expected to face scrutiny under both antitrust law and the Committee on Foreign Investment in the United States (CFIUS), on top of the standard Hart-Scott-Rodino review and a PTC shareholder vote. Regulators and markets have grown more sensitive to foreign ownership of software that touches industrial supply chains, so the review is unlikely to be a rubber stamp. PTC would owe Schneider a $700 million termination fee if it walks away for a better offer.

The companies are targeting a close by the third quarter of 2027 — an unusually long runway that underscores how much regulatory paperwork a deal this size requires. Until then, PTC keeps operating as an independent public company, earnings calls and all, while Wall Street watches whether Schneider's roughly $23.7 billion bet on "Energy and Industrial Intelligence" pays off — or whether a rival bidder decides $205 a share still leaves money on the table.
