Madison Air Solutions Inc. raised $2.23 billion in the largest U.S. industrial initial public offering in nearly three decades, with its shares closing up 18 percent as investors bought into a key supplier for the artificial intelligence infrastructure boom.
"Madison Air is a large industrial with tailwinds from data center buildouts, something we've also seen before," said Matt Kennedy, senior strategist at Renaissance Capital, a provider of IPO-focused research.
The Chicago-based company sold 82.7 million shares for $27 each, at the top of its marketed range, giving it an initial valuation of $13.2 billion. The stock (NYSE: MAIR) finished its first day of trading at $31.75 in New York, pushing its market capitalization to approximately $15.5 billion. The offering was the largest industrial debut since the 1990s and the biggest U.S. IPO of the year, surpassing Forgent Power's $1.74 billion float in February.
The strong debut reflects a high appetite for companies providing essential "picks and shovels" for the expansion of AI, which requires massive data centers with specialized cooling systems. With data center capital expenditures by major cloud providers approaching $700 billion, the market for cooling solutions is expanding rapidly, positioning suppliers like Madison Air for sustained demand.
Madison Air, which operates 30 brands providing ventilation and cooling systems, derives about 20 percent of its revenue from the data center sector. The company's products address a North American market estimated at $40 billion, where it currently holds an 8 percent share. Its commercial business accounted for 66 percent of its $3.34 billion in revenue last year.
While revenue grew 27 percent from $2.62 billion in the prior year, the company's profitability has faced headwinds. Net income declined to $124 million from $236 million, a drop partially attributed to more than $51 million in increased costs from tariffs on imported metals. The company reported a project backlog of $2.02 billion as of December 31.
The successful listing follows strong market performance from other companies linked to the data center cooling theme. Chemours Co., which produces cooling fluids, has seen its stock price increase 94 percent this year after receiving a positive rating from UBS based on its role in the sector.
Goldman Sachs, Barclays, Jefferies and Wells Fargo Securities acted as joint lead book-running managers for the IPO.
