Mainboard IPOs Opening This Week
1. HD Fire Protect IPO (13-15 October)
The ₹712.31 crore issue is entirely an offer for sale (OFS) of 2.63 crore shares by promoters Harish Narshi Dharamshi and Kusum Harish Dharamshi — the company gets no proceeds. The fire protection equipment maker fixed the band at ₹258-271 with a 55-share lot (₹14,905 minimum at the upper band). Anchor book: 12 Oct; allotment expected 16 Oct; listing 21 Oct on BSE and NSE. Grey market premium is around ₹75 — the strongest of the week — though GMP is unofficial and can move quickly. Read the full HD Fire Protect IPO deep-dive.
2. Fusion CX IPO (14-16 October)
The customer-experience BPO's ₹702 crore issue combines a ₹500 crore fresh issue (₹275 crore earmarked for debt repayment) with a ₹202 crore OFS. Band: ₹275-289, lot of 51 shares (₹14,739 minimum).

3. Tonbo Imaging IPO (15-19 October)
The defence-tech company's price band of ₹665-700 was announced this morning. It is a pure OFS of 1.22 crore shares (~₹852 crore), with a 21-share lot (₹14,700 minimum). FY26 saw revenue decline 22.7% YoY, so the implied ~76x P/E versus peers deserves scrutiny. GMP is around ₹270 (unofficial). Read the full Tonbo Imaging IPO review.
4. Zetwerk Manufacturing Business IPO (reportedly 15-19 October)
The contract-manufacturing unicorn is reported to be targeting a ~₹5,000 crore issue — ₹2,600 crore fresh plus an OFS of up to 9.68 crore shares — at a ~₹27,000 crore valuation. If dates hold, listing is targeted for 23 Oct. Price band and lot size are not yet announced. Read the Zetwerk IPO details.
5. Bonfiglioli Transmissions IPO (reportedly 15-19 October)

6. Sahajanand Medical Technologies IPO (15-19 October)
