Samsung in Talks to Buy Modine, Sending the Cooling Stock Up 29%

Modine (NYSE:MOD) jumped $30.80, or 29.03%, to $136.90 in after-hours trading on November 12, 2026, after Bloomberg News reported that Samsung Electronics is in talks to buy the Wisconsin-based maker of data center cooling systems. The stock had closed the regular session at $106.10, down 0.53%, valuing the company at roughly $5.6 billion.

Even after the pop, the price sits about 58% below its 52-week high of $323.25, by our estimate. That gap tells you the market sees a real chance of a deal but doubts it will close.

What do we actually know about the talks?

Bloomberg's report cites people familiar with the matter. A deal could come together within weeks, but no final decision has been made, and talks could still fall apart if another bidder steps in.

No price or terms have surfaced, and neither company has confirmed or commented on the discussions. Modine's only release on November 12 announced its Analyst and Investor Day — an event that had already been scheduled before the report landed.

Why would Samsung want Modine?

The logic is thermal. AI chips run hotter as they get denser, pushing data center operators toward liquid cooling, and Samsung has been building a cooling business to serve that shift. In May 2025, it agreed to buy Germany's FlaktGroup for 1.5 billion euros, and it's now spending 240 billion won on a FlaktGroup production line in Gwangju.

Modine would add something Samsung doesn't have: direct supply relationships with U.S. hyperscalers, the largest cloud operators.

Modine has also reshaped itself into a pure cooling play. On October 1, 2026, it spun off its Performance Technologies unit and merged it with Gentherm (NASDAQ:THRM) through a Reverse Morris Trust — a tax-efficient way to split off a business and combine it with another company.

What's left is growing fast. Data Centers revenue hit $439.7 million in the fiscal second quarter, up 95%. Quarterly orders passed $1 billion for the first time.

What problems would a buyer inherit?

The growth comes with pain. Adjusted EPS of $1.35 missed the $1.52 estimate, and gross margin fell 160 basis points to 20.7% as material, component, and tariff costs rose. Free cash flow was negative $140.6 million while Modine built up inventory and added capacity.

Those problems stay whether or not Samsung goes ahead. A foreign buyer could also face regulatory scrutiny: the Committee on Foreign Investment in the United States can delay or block a deal involving a supplier to American AI infrastructure.

For scale, compare Vertiv (NYSE:VRT). It closed at $209.64, up 1.52%, and traded at $216.46 after hours, up 3.25%, with a market value of $80.72 billion — roughly fourteen times Modine's. That shows how small Modine still is in this market.

What happens if the talks fail?

The stock then has to stand on its own results, and those just missed. Modine fell about 15% after its November 3 quarterly report, and one broker cut its price target to $180 from $302. Shares had dropped 38.46% over the past month.

In a no-deal scenario, the $106.10 close is the realistic starting point. Vertiv offers wider cooling exposure — it's far larger, sells both power and cooling equipment, and its price doesn't rest on one unconfirmed report.

On November 4, CEO Neil Brinker said demand "far exceeds our capacity." Modine presents new long-term targets at its Investor Day in Chicago on November 18. Until a signed merger agreement shows up in an SEC filing, those targets will matter more to the price than the reported talks.
