Madison Air Solutions saw a remarkable 18% surge in its IPO on Thursday, managing to raise a substantial $2.23 billion. This achievement marked the largest U.S. industrial IPO in almost thirty years. Closing at $31.75 per share, the strong investor interest in this industrial company linked to the AI infrastructure expansion was evident.
Headquartered in Chicago, Madison Air Solutions specializes in designing and manufacturing ventilation, filtration, and cooling systems for various facilities such as data centers, semiconductor manufacturing plants, life sciences buildings, and commercial establishments. Of particular interest to investors is the fact that MAIR offers liquid, hybrid, and air-cooling equipment tailored for data centers, aligning it closely with the ongoing AI buildout trend.
Approximately 20% of MAIR’s business is attributed to data centers. With operations spanning 30 brands, the company reported a revenue of $3.34 billion in 2025, up from $2.62 billion the previous year. However, net income saw a decline from $236 million to $124 million. Like many U.S.-based industrial firms, MAIR faces challenges from President Trump’s tariffs, with imported metals leading to over $51 million in additional costs in the previous year.
Following the IPO, MAIR closed at $31.75, above its $27 offering price, resulting in a market capitalization of $15.5 billion. During premarket trading in New York, shares are currently hovering around $32.
In the realm of data center cooling, a previous piece titled “A Chilling Opportunity” highlighted UBS analyst Joshua Spector’s positive outlook on Chemours as a prime player in coolant solutions for data centers. Chemours has seen a significant 94% increase year-to-date.
In a recent update, Goldman analyst Mark Delaney shed light on the data center expansion, stating, “Datacenter capex from leading public hyperscalers is now approaching ~$700 billion, roughly 10x the level in 2020.” This forecast indicates that as technology advances and the need for energy and cooling solutions grows, companies like MAIR and Chemours are poised to benefit significantly.
