April 6 (Reuters) – Ventilation and filtration systems provider Madison Air Solutions said on Monday it was targeting a valuation of up to $13.2 billion in ​its U.S. initial public offering, in what ‌could be the biggest U.S. IPO so far this year.

The Chicago, Illinois-based company is seeking up to $2.23 billion by offering roughly 82.7 million shares priced between $25 and $27 apiece.

The U.S. IPO market ‌has ​struggled to gain traction over the ⁠past two months as ⁠prolonged market volatility linked to the ongoing Middle East conflict has slowed activity. Still, some corporate issuers, including defensible industrial names, have continued to steam ​ahead.

Madison Air was formed under the leadership of Larry Gies, founder and CEO of privately held Madison ⁠Industries, through a series of ⁠acquisitions beginning in 2017, according to its ​website.

Its brands include Nortek Air Solutions, Nortek Data Center ​Cooling and Big Ass Fans, which provide air quality ‌and thermal management products for commercial, industrial and data center applications.

Forgent Power Solutions’ $1.74 billion IPO in February is currently the biggest U.S. IPO this year, according ⁠to data from Dealogic.

Morgan Stanley’s Counterpoint Global, Durable Capital Partners and HRTG GPE have separately indicated interest in purchasing up ⁠to $525 million of ‌shares in the offering.

Separately, Larry Gies’ ⁠Madison Industries plans to buy $100 million of ​Madison ‌Air shares in a concurrent private placement.

Goldman ​Sachs, Barclays, ⁠Jefferies and Wells Fargo Securities are the joint lead book-running managers for the offering.

Madison Air will list on the New York Stock Exchange under the symbol “MAIR”.
