• Meshflow Acquisition Corp (MESH), $352M
• NMP Acquisition Corp. (NMP), $119M

• Proem Acquisition Corp. I (PAAC), $132M
• Futurewave Acquisition Corp (FWAC), $86.3M
• Harvard Ave Acquisition Corp (HAVA), $149M

Approved by shareholders

7 combinations went to a vote and passed. At that point the redemption window has run and what remains in trust is what the deal has to work with.

• Immunovant, Inc. (IMVT)
• Inflection Point Acquisition Corp. V (IPEX), $87.6M
• Greenland Mines Ltd (GRML), $19.6M
• Hudson Acquisition I Corp., $25.5M

• Inflection Point Acquisition Corp. V (IPEX), $87.6M
• ONE Nuclear Energy Inc. (ONEN), $200M

Wound up

• NewHold Investment Corp. III (NHIC), $213M
• ONE Nuclear Energy Inc. (ONEN), $200M
• Inflection Point Acquisition Corp. V (IPEX), $87.6M
• Keen Vision Acquisition Corp. (KVACF), $13.4M
