Well, that didn’t last. Back in May, Stratasys agreed to buy Markforged from Nano Dimension for $42.5 million in cash. On November 11, the the companies “mutually terminated” the deal. Nano disclosed this in an 8-K filing to the U.S. Securities and Exchange Commission that is all of one paragraph long, and Stratasys mentioned it on its Q3 earnings call the next morning.

The stated reason: both sides “determined that obtaining the needed regulatory approvals to close would take materially longer, and be more expensive, than initially anticipated.” That’s it. No regulator is named, no termination fee is disclosed, and nothing is said about what happens to Markforged. Stratasys CEO Yoav Zeif did tell analysts there were “no financial repercussions.”

Let’s dig into the three things I wanted to understand: why the deal failed, why we’re hearing about it now, and whether it has implications for other deals in our PLMish world (cough cough, Schneider Electric + PTC). Given the very short statement, it’s unclear whether there was a specific regulator who objected (and whose objections couldn’t be countered, like when Synopsys and Ansys had to sell off parts of their businesses before the deal was approved).

First, a quick recap: Nano Dimension bought Markforged in April 2025 for about $116 million, part of a buying spree that also included Desktop Metal (which went into Chapter 11 a few months later). After an activist campaign remade its board and management, Nano switched from accumulating 3D printing assets to selling them. Markforged was to go to Stratasys, minus the metal binder jetting line, which Nano planned to keep. Markforged had about $70 million in 2025 revenue (including binder jetting), so the price was roughly 0.6x sales. For Nano, the sale was supposed to cut roughly $15 million a year from its cash burn.

Stratasys wanted Markforged’s continuous carbon fiber (CCF) FFF technology, its metal filament printing, its Digital Forge software, and its reseller network, all aimed at aerospace and defense tooling, fixtures and production parts.

Next, why might the the companies have decided to pull the plug? Neither company has said anything useful, but here are a few guesses:

• It probably isn’t related to a mandatory U.S. antitrust filing. At $42.5 million, the deal sits well below the 2026 Hart-Scott-Rodino threshold of $133.9 million, so a U.S. premerger notification wasn’t automatically required. (The FTC and DOJ can still look at deals below the threshold, but they don’t have to.)
• Even so, the competitive overlap is real and could pose a problem for regulators. Stratasys invented FDM and is still the leader in industrial material extrusion. Markforged is one of the few other serious industrial FFF brands, particularly in composites. Combining the two hands a lot of the industrial extrusion market to one vendor, which could raise questions in some countries where both companies sell.
• National security makes everything slower. Both Stratasys and Nano are Israeli companies; Markforged is a U.S. business whose growth is increasingly in the defense industries. That raises the possibility of foreign-investment and security reviews on top of competition reviews.

Whatever the specific issues, Mr. Zeif made clear Stratasys wasn’t willing to fight for this acquisition. He told investors “we wanted the deal,” but he also called Markforged “a complementary technology” and said “it is not a transformative” one for Stratasys, adding that “there are alternatives.” Translation: nice to have, not worth a long regulatory slog.

Why announce all of this now? The timing is the most interesting part of this. On November 3, Moshe Rozenbaum, interim CEO since July, is named Nano’s permanent CEO. Then, on November 5, Nano reports Q3 results and says the Markforged sale “remains ongoing, with closing expected in the fourth quarter of 2026.” Important to note: Nano didn’t hold an earnings call, citing ongoing strategic initiatives. Then, on November 11, Nano files with the SEC that the deal is terminated. Finally, November 12, Stratasys reports Q3 and holds its earnings call.

That’s six days from “closing in Q4” to “never mind”.

This suggests to me that the companies realized fairly suddenly that the regulatory clock had perhaps run out. But the real driving force behind the cancellation was likely the timing of Stratasys’s Q3 report. When the deal was announced, Stratasys said it would update its guidance once the transaction closed. Going into its November 12 release, it had two choices: explain a pending deal that was now likely to slip into 2027, or just stop talking about it. Abandoning the acquisition let Stratasys present a report focused on its business and not issues with the Markforged acquisition. Stratasys’ Q3 revenue was up 4% to $143 million, led by aerospace and defense (up more than 35%). The company lowered full-year revenue guidance to $556 million to $561 million (from $565 million to $575 million), which management attributed to large production orders taking longer to close.

Of course, Markforged is now back in limbo. Nano can keep running it, look for another buyer (likely one with less overlap and therefore an easier regulatory path), or break it up further. Nano is “exploring its strategic alternatives,” and TCT Magazine reports that may include a pivot away from additive manufacturing altogether, so Markforged might be on the block sooner rather than later. TBD.

This whole saga, which started with Nano’s hostile bid for Stratasys in 2023, keeps finding new chapters. I’m not sure this is the last one.

One last thing: what does this mean for our broader PLMish world? Does the companies’ finding that “obtaining the needed regulatory approvals to close would take materially longer, and be more expensive, than initially anticipated” mean anything for deals that have been announced or are in the works?

Maybe. The deals most at risk are purchases in concentrated niches by the category leader, which is exactly what Stratasys + Markforged could do. PLMish vendors constantly buy small CAE, CAM, and niche PLM companies, but most of those deals don’t have this kind of overlap.

We’re all thinking about Schneider Electric buying PTC, and if it could face issues. Possibly, of course, but there is a lot less head-to-head overlap. I saw one analysis that expects regulatory (in other words, competition-related) look-sees in EU, UK, China, and other jurisdictions. Another said that this will likely need a foreign-investment review in the U.S. because a French company is buying American software that defense and aerospace manufacturers rely on.

We don’t know, but it’s possible that this sort of defense-plus-foreign-buyer combination slowed the Stratasys+Markforged deal — but the situations are not the same. AVEVA (process/plant) and PTC (discrete product CAD/PLM) are mostly complementary, so I’d expect delay and possibly security conditions rather than a fatal antitrust problem. The long timeline (the deal is expected to close by Q3 2027) is already built into the schedule.

Too, how strategic is the deal? Stratasys’s CEO walked away from a deal he called “not transformative.” By contrast, the PTC deal is Schneider’s largest acquisition to date, surpassing its 2023 buyout of Aveva. Buyers push through long reviews when the deal is central to their strategy. Synopsys/Ansys went through DOJ, EU, and China reviews and still closed, with divestitures by both companies to make it possible. When the prospect is big enough, higher hurdles will be jumped.

My bottom line: the Markforged failure is a one-off caused by an odd mix of seller, buyer, and product overlap. But the broader lesson is that “regulatory approvals” now covers far more than U.S. antitrust — and we’re learning more about that with every deal.
