The IPO provides significant deleveraging that will improve cash flow and financial flexibility. However, the dual-class structure with 95.2% founder control limits shareholder influence. The strong growth in mission-critical air solutions for data centers, healthcare, and residential markets provides a compelling growth story, but investors should monitor integration of the $2.3 billion AprilAire acquisition and execution of the 80/20 operational model.
