Madison Air Brings a $2.2 Billion IPO With Real Book Support

CHICAGO, April 10, 2026 - Madison Air Solutions is not just another industrial issuer trying to catch an IPO window. The air-quality and thermal-management platform is asking public investors to absorb more than $2 billion of primary stock, while named cornerstone demand, a founder-backed private placement and a deep bank group give the book more shape than most deals on the calendar.

Madison Air is marketing 82,692,308 Class A shares at $25 to $27 each, a range that would raise roughly $2.07 billion to $2.23 billion before the underwriters' option. At the $26 midpoint, the share count implied in the prospectus points to an equity value of about $12.7 billion after the offering and related transactions. The company has NYSE approval to list under MAIR, and its April 6 roadshow launch put the deal into the active pricing lane.

The demand signal is unusually specific. Counterpoint Global, part of Morgan Stanley Investment Management, Durable Capital Partners and HRTG GPE have indicated interest in buying up to $525 million of Class A stock. Those indications are not binding, and the prospectus is explicit that the investors may buy more, less or nothing. Still, named interest at that size matters in a market where large IPOs need visible anchors before generalist accounts lean in.

There is a second backstop from inside the founder ecosystem. Madison Industries Holdings, controlled by founder Larry Gies, is expected to buy $100 million of Class B stock in a concurrent private placement at the IPO price. The underwriters do not get a discount or commission on that private-placement stock, but public buyers should read it for what it is: confidence from the control holder, not a governance concession.

The syndicate is built for a real institutional sale. Goldman Sachs, Barclays, Jefferies and Wells Fargo Securities are joint lead book-running managers. BofA Securities, Citi, Baird, RBC, Guggenheim, Santander, Wolfe | Nomura Alliance and CIBC are also listed as joint bookrunners, with Comerica, William Blair, Stifel, Capital One and PNC as co-managers. That is the bank wall a sponsor-shaped, acquisition-built industrial platform needs if it wants to price size rather than just open a token public float.

Madison Air's operating case has more texture than the usual HVAC-adjacent roll-up. Its brands include Addison, AprilAire, Big Ass Fans, Broan-NuTone, Nortek Air Solutions, Nortek Data Center Cooling and Reznor. The company sells into commercial and residential air markets, including data centers, semiconductor facilities, healthcare, education, logistics and homes. The public-market pitch is that better air is tied to uptime, energy efficiency, compliance and health, not just comfort.

The financials support the scale, while also showing the burden investors are being asked to refinance. Net sales rose to $3.34 billion in 2025 from $2.62 billion in 2024. Adjusted EBITDA increased to $890.7 million from $674.2 million, and adjusted EBITDA margin reached 26.7%. Orders rose to $4.39 billion and backlog more than doubled to $2.02 billion. But interest and financing expense was $351.3 million in 2025, and GAAP net income was $124.3 million.

That is why the use of proceeds matters. At the midpoint, Madison Air estimates $2.07 billion of IPO net proceeds, plus $100 million from the private placement. It expects to use about $2.17 billion to repay borrowings under its initial term loan facility, including accrued and unpaid interest. The deal is a deleveraging transaction before it is a growth-capital story.

Governance is the other price of admission. After the offering and private placement, Gies is expected to control 95.2% of the voting power, assuming no exercise of the underwriters' option, through Class B stock held by Madison Industries Holdings. Madison Air will be a controlled company under NYSE rules, and Gies may initially nominate all directors under a director nomination agreement.

That leaves a clean market test. Madison Air brings scale, EBITDA, data-center and indoor-air exposure, named cornerstone interest and a serious syndicate. It also brings leverage, acquisition complexity and a founder-control structure that leaves Class A buyers with little practical say. If the book holds at this size, it will say something useful about how much appetite remains for profitable industrial platforms when the story comes with both real demand signals and real strings attached.
