Important Caveats for Grey Market Watchers
Before tracking the Tonbo Imaging Mainboard IPO GMP, keep these risk factors in view:
- 100% OFS Structure: The offering is entirely an Offer for Sale of 1.22 crore equity shares by promoters and selling shareholders; Tonbo Imaging India Ltd receives zero fresh capital on its corporate balance sheet from the Tonbo Imaging India IPO.
- Lumpy Revenue & Defence Procurement Cycles: Revenue delivery in the defence sector is subject to milestone-based shipments, government approvals, and tender procurement timelines, which can result in quarterly operational lumpiness.
- Price Discovery: Final listing gains for Tonbo Imaging depend strictly on official exchange order matching when the stock debuts on the Mainboard IPO list.
