April 15 (Reuters) – Indoor air systems provider Madison Air Solutions said on Wednesday it had raised $2.23 billion in the biggest U.S. initial public offering so far this ​year.

The Chicago, Illinois-based heating, ventilation and air conditioning (HVAC) firm ‌sold 82.7 million shares in the IPO at $27 each, compared with the marketed range of $25 to $27. The IPO valued it at $13.2 billion.

Investors have shown appetite for infrastructure and data center-linked businesses, drawn by rising cooling and power needs ‌from ​AI expansion, amid geopolitical tensions in the ⁠Middle East that have ⁠kept the broader U.S. IPO market in jitters.

“Madison Air is a large industrial with tailwinds from data center buildouts, something we’ve also seen before (e.g. Forgent Power Solutions, SOLV Energy),” said Matt ​Kennedy, senior ‍strategist at Renaissance Capital, a provider of IPO-focused research and ETFs.

Madison Air estimates its products address a roughly $40 billion ⁠North American market, where it holds ⁠about an 8% share, according to its filing, with ​data centres among the faster‑growing verticals.

Before Madison Air, Forgent Power’s $1.74 billion ​offering in February was the biggest U.S. IPO this ‌year, according to data compiled by Dealogic.

Founded in 2017 through a series of acquisitions, Madison Air provides air quality solutions for residential and commercial clients across a range of sectors, including data centers, ⁠advanced manufacturing, education, and health care.

The company’s commercial business accounted for 66% of total sales last year, with the remainder coming from the ⁠residential segment.

Madison Air, ‌formerly known as Madison Indoor Air Quality, was ⁠formed under the leadership of Larry Gies, the ​founder ‌and CEO of privately held Madison Industries. It ​had a ⁠backlog of $2.02 billion, as of December 31.

Goldman Sachs, Barclays, Jefferies and Wells Fargo Securities were the joint lead book-running managers. Madison Air will begin trading on the NYSE on Thursday under the symbol “MAIR”.
