Is the Tonbo Imaging IPO an OFS?
Yes. The reported offer is entirely an offer for sale. Tonbo Imaging India’s draft red herring prospectus describes up to 18,085,246 existing shares for sale and states that the company will not receive the offer proceeds. Selling shareholders receive the proceeds, after their respective offer expenses and taxes. An OFS therefore provides an exit opportunity for selling shareholders; it is not a new-share capital raise for the issuer.
The share count and proceeds treatment are described in the draft offer documents filed with SEBI. Because the cited document is a draft, consult the final prospectus for the definitive offer structure.

The prospectus further states that SEBI has not recommended or approved the shares and does not guarantee the prospectus’s accuracy or adequacy.

Business demand and revenue visibility can vary
The draft prospectus identifies geopolitical factors, government budget cycles and tender-based procurement as sources of cyclicality and weak revenue visibility. Defence spending or the company’s product category alone does not establish future orders, margins or results. Any industry or market-share figures in the prospectus that rely on its commissioned Frost & Sullivan report should be read with that attribution in mind.
