Diffusion Engineers Limited
Promoters Nitin Garg · Chitra Garg · Prashant Garg
Against an issue price of ₹168. Split- and bonus-adjusted official closes — a past move, never a forecast.
Diffusion Engineers Limited raised ₹150 crore through a mainboard initial public offer.
The filing places it in Engineering Services and names three promoters: Nitin Garg, Chitra Garg and Prashant Garg.
The book was open from 26 September 2024 to 30 September 2024.
The issue was priced at ₹168 a share, from a band of ₹159 to ₹168.
The whole offer is a fresh issue of shares — ₹158 crore raised by the company itself.
The issuer reported the offer subscribed 112.0 times the shares on offer. That is its own final figure, filed with the exchange after the book closed — not a reading we took while bidding was open.
The shares listed on 4 October 2024.
The last official close on file is ₹444 (21 September 2026), which is 164.3% above the issue price.
It now trades as DIFFNKG, and its filed financials are on its company page.
Shares sold in the issue at ₹168 last closed at ₹444.05.

No offer-for-sale leg — every share in this offer is newly issued, so the whole amount raised goes to the company.

This is the issuer’s own final figure, filed with the exchange once bidding had closed — not a reading we took while the book was open. The exchange publishes only a running cumulative figure and no history, so for an issue nobody polled live this filing is the only account of the book that exists. It covers the whole offer and carries no breakdown by category and no timestamp.

No part of the offer was set aside for market maker or other.
The portion of the offer set aside for each category before bidding opened, as the issuer filed it. The anchor allocation is filed as its own line rather than inside the institutional one, so these add up to the whole offer. Shares as filed; the percentages are computed against the offer's own share count.
We did not poll this issue while its book was open. The exchange publishes only the current cumulative figure and no history, so a subscription series cannot be reconstructed after an issue closes.
We have not extracted an anchor allotment list for this issue.

Computed from the SEBI ICDR 2018 lock-in rules, not disclosed by the issuer or the exchange. The regulation counts from the date of allotment, which no feed we ingest publishes, so these are counted from the listing date and fall at most two to three business days later than the true expiry.
Every offer document must set out the reasoning behind its own price: what the company earned in the years before it came to market, and what multiple of those earnings it is asking for. This is that chapter — the issuer’s argument for its price, not our assessment of it.

Everything we extracted from this issue's offer document is the pricing justification rather than the restated statements — it is shown under how the offer was priced. The restated financial statements themselves have not been extracted for this issue.
We have not extracted this section from the offer document for this issue yet. It is read from the abridged prospectus, and several offer documents are served as .zip archives or as scanned pages with no text layer.
The offer document must name the listed companies the issuer considers comparable, and print their valuation figures beside its own. This is that list — the issuer’s choice of comparison, not ours.
