Samsung in Talks to Buy Modine as Cooling Maker's Stock Jumps 29%

Modine Manufacturing (NYSE: MOD) jumped 29.03% in after-hours trading on November 12, 2026, after Bloomberg News reported that Samsung Electronics is in talks to acquire the Wisconsin-based data center cooling company. The stock traded at $136.90 after hours, up $30.80 from the regular close.

That close, $106.10, valued the company at roughly $5.6 billion. By the source's estimate, the close sat about 67% below the 52-week high of $323.25. The shares had fallen 38.46% over the prior month. The decline included a drop of about 15% after quarterly results on November 3 missed expectations. One broker cut its price target to $180 from $302.

What has actually been agreed?

Nothing. The Bloomberg report cites people familiar with the matter. A deal could come together within weeks, but no final decision has been made. Talks could still fall apart if another bidder steps in. No price or terms have been disclosed. Neither company has confirmed the discussions or commented on them. Modine's only release on November 12 announced its Analyst and Investor Day, an event scheduled before the report.

Why does Samsung want Modine?

AI chips run hotter as they grow denser. That pushes data center operators toward liquid cooling. 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. It is also spending 240 billion won on a FlaktGroup production line in Gwangju.

Modine would hand Samsung direct supply relationships with U.S. hyperscalers, the largest cloud operators. The company refocused on cooling with an October 1, 2026 spin-off. It merged its Performance Technologies unit with Gentherm (NASDAQ: THRM) through a Reverse Morris Trust, a tax-efficient structure for splitting off and combining a business.

What remains is a pure cooling company with strong momentum:

• Data Centers revenue reached $439.7 million in the fiscal second quarter, up 95% year over year.
• Quarterly orders passed $1 billion for the first time.
• On November 4, CEO Neil Brinker said demand "far exceeds our capacity."

What problems would a buyer inherit?

The growth masks profit pressure. Adjusted EPS of $1.35 missed the $1.52 estimate. Gross margin fell 160 basis points to 20.7% on higher material, component and tariff costs. Free cash flow was negative $140.6 million as Modine built inventory and added capacity. Those problems persist whether or not Samsung proceeds.

A foreign buyer could also face regulatory review. The Committee on Foreign Investment in the United States can delay or block a deal involving a supplier to American AI infrastructure.

For scale, Vertiv (NYSE: VRT) closed at $209.64, up 1.52%, and traded at $216.46 after hours, up 3.25%. Its $80.72 billion market value shows how small Modine remains in this market.

What does the after-hours price say about deal odds?

The jump still leaves the stock far below its peak. By the source's estimate, even $136.90 sits about 58% below the high. The market appears to price a real chance of a deal but doubts it will close. If talks fail, the stock must rely on its own results, which just missed estimates. In that case, the $106.10 close is the realistic starting point. Vertiv offers wider cooling exposure, sells both power and cooling equipment, and its price does not rest on one unconfirmed report.

Modine will present new long-term targets at its Investor Day in Chicago on November 18. Until a signed merger agreement appears in an SEC filing, those targets will matter more to the share price than the reported talks.
