Filtration and ventilation roll-up Madison Air Solutions is set to launch the biggest initial public offering of 2026, aiming to raise approximately $2.2 billion. The deal will test investor appetite for private equity-backed industrial firms at a premium valuation, valuing the company at $12.7 billion.
In a letter to prospective investors, CEO Jill Wyant wrote that the company pursues “high-value niches adjacent to traditional HVAC” with “custom and semi-engineered solutions to mission-critical environments where air is vital to customer success.”
The company, a collection of 13 acquisitions since 2017, will be valued at roughly 17 times its adjusted pro forma 2025 Ebitda of $937 million and nearly 30 times adjusted pro forma net income. This valuation is comparable to HVAC leader Trane but represents a premium to Carrier and Lennox International, which trade at around 23 times trailing earnings. The IPO is expected to price Wednesday and begin trading Thursday on the NYSE under the ticker MAIR.
The offering will serve as a crucial test for the IPO market, particularly for industrial companies and private equity exits. A successful debut for Madison, controlled by billionaire Larry Gies, could bolster confidence in the sector. The bulk of the IPO proceeds will be used to reduce debt from $5.7 billion to $3.5 billion, a move supported by a $100 million investment from Gies and indications of interest from cornerstone investors like Counterpoint Global and Durable Capital Partners for up to $525 million of stock.
Strategic Focus on Air Purity
Madison is positioning itself as a specialist in air purity rather than a traditional HVAC manufacturer. The company, which owns brands like AprilAire and Big Ass Fans, emphasizes its role in filtration, ventilation, and humidity control for mission-critical environments. This focus on what it calls “Return on Air” targets high-value niches where air quality is essential for customer operations, such as data centers and semiconductor plants, which contribute about 20% of commercial revenue.
The company has demonstrated strong growth, with revenue averaging 8 percent annually over the past five years and adjusted Ebitda margins exceeding 25 percent. However, some of that growth has been fueled by its acquisition strategy. Organic revenue growth was a strong 12.4 percent last year but slowed to 2.9 percent in 2024, with nearly all of it originating from the commercial side as the residential market remains soft.
