US IPO Week Ahead: Wave of potential launches set to crash over a quiet IPO calendar

There are currently no major IPOs scheduled for the short Memorial Day week ahead, though some small deals may join the calendar late.

While it looks quiet for now, several notable names in the pipeline could launch in the coming week, including:

• Honeywell’s quantum computing carve-out Quantinuum (QNT) and natural gas engine maker INNIO Holding (INIO), both of which are on file for estimated $1.5 billion IPOs.
• Aerospace equipment manufacturer Applied Aerospace & Defense (AADX), which is on file for an estimated $350 million IPO.
• Scooter rental platform Lime (LIME) and coastal property insurer Safepoint Holdings (SFPT), which are on file for estimated $250 million IPOs.
• Natural gas mineral and royalty business WhiteHawk Minerals (WHK), which is on file for a $100 million IPO.
