Madison Air to Buy ebm-papst for $5.4 Billion as AI Cooling Demand Grows

Madison Air Solutions has agreed to acquire Germany’s ebm-papst for an enterprise purchase price of $5.4 billion, bringing a major maker of fans, motors and airflow systems into a portfolio that already sells cooling equipment for data centers. The acquisition comes as artificial-intelligence infrastructure is increasing the amount of heat that data-center operators need to remove, turning cooling and airflow hardware into a more important part of the AI investment chain.

The deal is broader than data centers. ebm-papst sells into heating, ventilation, air-conditioning and refrigeration systems, along with other industrial and mission-critical applications. But the timing matters. Both companies have identified data-center demand as an important source of growth, and Madison Air is buying technology that sits closer to the core airflow components used inside many cooling systems.

Madison Air said the $5.4 billion headline enterprise value falls to an effective $5.0 billion after the estimated value of future tax savings. The company expects ebm-papst to generate about $2.8 billion of revenue and $343 million of adjusted EBITDA in 2026. On that basis, Madison Air puts the effective purchase price at 14.6 times forecast 2026 adjusted EBITDA, or about 10 times after including the annual cost synergies it expects to achieve.

What Madison Air is actually buying

Founded in 1963 and headquartered in Mulfingen, Germany, ebm-papst specializes in high-performance airflow technology and integrated electronically commutated fan and motor systems. Madison Air said ebm-papst has more than 250 million fans installed worldwide within its Air Technology business and a portfolio supported by more than 1,200 patents.

That matters because fans are not merely an accessory to the cooling system Madison Air already sells. ebm-papst’s products can be specified early in the design of HVAC and refrigeration systems, which gives the supplier a role in how equipment is engineered for efficiency, reliability and operating cost. Madison Air is already an ebm-papst customer, so the acquisition would move a key technology supplier inside the same corporate group.

In its acquisition announcement, Madison Air said the combination would add about $30 billion to its addressable market and nearly double the opportunity it sees across its existing businesses. Management also expects the larger installed base to create more aftermarket and service revenue, while ebm-papst gives Madison Air a much stronger presence in Europe and Asia.

The strategic logic is therefore partly vertical integration and partly geography. Madison Air already owns brands including Nortek Air Solutions, Nortek Data Center Cooling and Big Ass Fans. Adding ebm-papst would give it more direct access to fan and motor technology while broadening the customer and channel base outside North America.

The German company is also large enough to materially change Madison Air’s scale. ebm-papst reported €2.236 billion of sales in the fiscal year ended March 2026, while its core Air Technology business grew about 12%. Madison Air, by comparison, reported $1.915 billion of net sales in the first half of 2026 and currently expects full-year sales of $3.825 billion to $3.925 billion.

AI infrastructure is making cooling a bigger strategic target

The strongest connection between the acquisition and the AI buildout is not a promise that every ebm-papst product will end up in an AI data center. It is the growing importance of thermal management as computing systems become denser and more power-hungry.

ebm-papst said at its annual press conference this year that its data-center business had become a major growth driver. The company linked that demand directly to the global expansion of digital infrastructure and rapid progress in AI, which it said is increasing the need for efficient, reliable and scalable cooling. It has been developing fan and pump products for data-center applications as well as software intended to optimize airflow and energy use.

Madison Air is seeing similar demand in its own results. In the second quarter, organic sales in its Commercial segment rose 22.3%, led by air, liquid and hybrid cooling, custom air handling and air movement solutions. Commercial orders were up 45% on a combined basis, with the company pointing to wins in mission-critical applications including liquid cooling.

That operating backdrop helps explain why an airflow manufacturer can command a multibillion-dollar valuation during an AI infrastructure cycle dominated in public discussion by chips. Servers built around advanced accelerators consume large amounts of power and produce heat that must be removed continuously. Cooling equipment, pumps, fans, heat exchangers, controls and related services therefore become part of the capital required to keep high-density computing capacity operating.

Reuters reported that ebm-papst views the acquisition as a way to gain better access to the U.S. data-center market, where cooling demand is rising as operators deploy more powerful chips and servers. CEO Klaus Geissdoerfer also told Reuters that joining Madison Air would give the German company access to U.S. capital markets that could support strategic options. The company plans to keep its headquarters in Mulfingen along with key research, development and production operations.

The AI exposure should still be kept in perspective. ebm-papst serves a broad set of HVAC, refrigeration and industrial markets, and Madison Air is not presenting the acquisition as a pure data-center deal. What AI changes is the growth profile of one of the most attractive end markets for both companies, making airflow and thermal-management technology more strategically valuable as server power density rises.

Financing makes the deal a leverage and execution test

The acquisition is also large enough to reshape Madison Air’s balance sheet. According to the company’s SEC filing, the purchase agreement sets an enterprise purchase price of €4.775 billion after adjustments for non-debt liabilities. The base purchase price is €4.367 billion, and Madison Air estimates that about €4.412 billion of cash would be payable at closing if the acquisition closes on December 31, 2026. It estimates future tax savings at about €371 million on a net-present-value basis.

Madison Air plans to fund the acquisition with cash on hand plus debt and equity financing. UniCredit and Wells Fargo have provided fully underwritten commitments for the debt portion, and the acquisition is not subject to a financing condition. The company also has a backstop equity commitment of up to €1.3 billion from Madison Solutions LLC, an entity affiliated with Madison Air founder and chairman Larry Gies.

That backstop is not the company’s expected source of equity funding. The filing says Madison Air currently plans to raise the needed financing from third-party debt and equity during the period before closing, and the commitment from Madison Solutions would be reduced euro for euro by money raised elsewhere.

The financing plan reverses part of the balance-sheet improvement Madison Air achieved only months ago. Its April initial public offering and concurrent private placement generated about $2.584 billion of net proceeds, which the company used with cash on hand to repay borrowings. Net leverage was 2.8 times at June 30. After the ebm-papst acquisition, Madison Air expects pro forma net leverage to be below 4.0 times at closing and is targeting a reduction to about 2.5 times within two years.

Management is counting on the acquired company’s cash generation and cost savings to help make that deleveraging plan work. Madison Air expects $160 million of annual run-rate cost synergies by the third year after closing and says the deal should add to adjusted earnings per share in the first full year after completion. Those are company forecasts rather than guaranteed outcomes, and the value of the acquisition will depend heavily on integration, financing costs and whether the projected savings arrive on schedule.

Regulatory approval is another condition. The SEC filing says closing requires merger-control and foreign-investment clearances as well as European Commission approval under the EU Foreign Subsidies Regulation. The parties are aiming to close around year-end 2026. Under specified circumstances in which sellers terminate because required conditions have not been satisfied, Madison Air could owe a €250 million break fee.

Until closing, the financing mix and leverage trajectory will be central investor variables. Madison Air expects pro forma net leverage below 4.0 times at completion and about 2.5 times within two years, so the acquisition will be judged not only on growth in cooling demand but also on cash generation and deleveraging. The companies are targeting a close around year-end 2026 after the required approvals.
