Analysis framework

Six areas, each labelled by published rules. Labels describe the evidence; they are not a rating or a recommendation. How labels are assigned

Business quality

Mixed evidence

Any other combination.

Concern: Revenue and profit fell in FY2026 Financial information (restated)
Supports: Latest full-year profit margin: 13.8% Financial information (restated)

Why it matters: A business that depends on one customer or product, or earns thin margins, has less room for error when conditions change.

What was evaluated

What the company sells and how it earns money (from the offer document)
Customer or product concentration disclosed as a risk
Latest full-year profit margin

Financial health

Mixed evidence

Any other combination.

Supports: Profitable in all 3 full years reviewed Financial information (restated)
Concern: Profit margin moved from 15.9% (FY2024) to 13.8% (FY2026) Financial information (restated)
Supports: Debt-to-equity in FY2026: 0.21x Financial information (restated)

Uncertain or missing

Operating cash flow for FY2026

Why it matters: Profits on paper only help shareholders if the business also generates cash and is not overloaded with debt.

What was evaluated

Profit after tax in each full financial year
Change in profit margin from the first to the latest year
Operating cash flow in the latest year
Borrowings relative to net worth (debt-to-equity)

Valuation

Mixed evidence

Any other combination (including a premium that is partly explained by faster growth).

Context: P/E at upper band: 78.8x (₹700 ÷ FY2026 diluted EPS ₹8.88) Price band; final issue price ₹700
Context: Peer median P/E: 83.9x across 5 peers. The IPO is 6% below the median Peer comparison (from RHP Basis for Offer Price); price as of BSE close on 7 Oct 2026

Uncertain or missing

Revenue growth comparison with peers
Profit margin comparison with peers

Why it matters: The price you pay matters as much as the quality of the business. Paying much more than similar companies needs a clear reason, such as faster growth.

What was evaluated

P/E at the upper price band, using latest full-year diluted EPS (pre-issue)
Median P/E of listed peers named in the offer document
Profit margin and revenue growth versus the same peers

Growth prospects

Needs attention

Revenue CAGR is below 5%, or revenue shrank over the period.

Concern: Revenue CAGR FY2024–FY2026: -7.5% Financial information (restated)
Concern: Growth went from 9.8% to -22.0% in the latest year Financial information (restated)
Context: Stated driver: Approved supplier under 'Make in India', with export capability free of US ITAR restrictions. Key strengths

Why it matters: IPO prices often assume growth will continue. Past growth is not a guarantee, but slowing growth is a reason to ask harder questions.

What was evaluated

Revenue compound annual growth rate (CAGR) across available full years
Whether growth slowed sharply in the latest year
Growth drivers described in the offer document

Material risks

Mixed evidence

One or two material risks were found.

Concern: Material: Revenue and profit fell in FY2026 Financial information (restated)
Concern: Material: Loss in the June 2026 quarter Financial information (restated): 30 Jun 2026
Context: Caution: 100% offer for sale; low promoter stake Issue details; Promoter holding

Uncertain or missing

Full risk-factor section has not been reviewed line by line; only summarised findings are shown

Why it matters: Offer documents list risks the company itself considers important. Reading them is the single best way to avoid surprises.

What was evaluated

Risk factors in the DRHP/RHP: concentration, litigation, related-party dealings, debt, dependence, regulation
Whether each risk is described as material in the reviewed sections

IPO structure & use of proceeds

Needs attention

75% or more of the issue is an offer for sale, OR promoter holding falls by 15 percentage points or more while shares are also being sold in an offer for sale.

Concern: 0% fresh issue (to the company), 100% offer for sale (to selling shareholders) Issue details
Context: Promoter holding: 18.6% → 14.6% Promoter holding

Why it matters: In an offer for sale the company receives nothing; existing shareholders are cashing out. Knowing who gets the money tells you what the IPO is for.

What was evaluated

Split between fresh issue (money to the company) and offer for sale (money to selling shareholders)
Whether the uses of fresh-issue money are stated with amounts
Change in promoter shareholding

Grey-market premium (GMP) and subscription figures are deliberately not part of this framework. They measure short-term demand, not business quality or value. Why?

Revenue growthcalculated What this means Change in revenue versus the previous full year. Why it matters: Steady growth suggests rising demand; erratic or slowing growth deserves a closer look.	—	+9.8%	-22.0%
Profit after tax What this means What's left after all expenses, interest and taxes. Negative means a loss. Why it matters: Profit is what ultimately belongs to shareholders.	₹68.5 cr	₹72.8 cr	₹50.9 cr

What this means Cash actually generated by day-to-day operations. Why it matters: Profit that never turns into cash is a warning sign; negative cash flow may mean the company needs more funding.	Data unavailable	Data unavailable	Data unavailable

Valuation

Is the price reasonable compared with similar listed companies? We show the numbers, how they were calculated, and what the comparison can't tell you.

₹665 – ₹700

: 21 shares
Minimum application: ₹14,700
Face value: ₹2

Price band; final issue price ₹700

Earnings-based valuation

used (FY2026, diluted): ₹8.88
at upper / lower band: 78.8x / 74.9x
Post-issue (upper band): ₹4,010 cr
Post-issue P/E (market cap ÷ latest profit): 78.8x

Calculation basis: P/E = price ÷ latest full-year diluted EPS as disclosed in the offer document (pre-issue shares). Post-issue P/E uses all shares outstanding after the IPO, so it reflects dilution from the fresh issue.

How does the price compare?

Mixed evidence

At the upper band, the P/E of 78.8x is 6% below the median (83.9x) of the 5 listed peers named in the offer document.

Label rule applied: Any other combination (including a premium that is partly explained by faster growth).

P/E: IPO vs listed peers

Peer comparison

Peer comparison (from RHP Basis for Offer Price); price as of BSE close on 7 Oct 2026

Peer valuation and profitability
Company	P/E
Tonbo Imaging India Ltd (IPO, upper band)	78.8x
Paras Defence and Space Technologies Ltd	117.9x
Data Patterns (India) Ltd	87.3x
Astra Microwave Products Ltd	83.9x
Zen Technologies Ltd	73.4x
Bharat Electronics Ltd	45.7x
Peer median	83.9x

Peer P/E ratios are for FY2026 as disclosed in the offer document. n/m = not meaningful. Peer revenue, margins and growth aren't in our data yet, so the comparison is P/E only.

Limitations of this comparison

Peers are those chosen in the offer document; they may differ in size, product mix or business model.
P/E uses a single year's earnings, which may be unusually high or low.
Peer P/E ratios change daily with share prices; offer-document figures are a snapshot.
P/E ignores debt. A company with heavy borrowings can look cheaper on P/E than it really is.

Risk analysis

2 of 3 findings are flagged as material. Each links to its source. These don't replace the full "Risk Factors" section of the RHP.

Material riskDependence on a product, input or market
Revenue and profit fell in FY2026
Total income fell from ₹474.39 crore (FY2025) to ₹369.94 crore (FY2026), and profit from ₹72.76 crore to ₹50.88 crore.
Why a beginner should care: Defence orders can be lumpy; a down year shows revenue isn't guaranteed to grow steadily.
Financial information (restated)
Material riskDebt & cash flow
Loss in the June 2026 quarter
A loss of ₹17.74 crore on total income of ₹37.32 crore in the three months to 30 June 2026.
Why a beginner should care: The most recent period before listing was loss-making, which the full-year P/E doesn't capture.
Financial information (restated): 30 Jun 2026
Worth knowingPromoter holding & offer for sale
100% offer for sale; low promoter stake
The company received no money from the IPO. Promoter holding fell from 18.58% to 14.56%.
Why a beginner should care: Founders with a small stake have less financial alignment with other shareholders.

IPO timeline

Lock-in details are in the RHP's Capital Structure section and have not yet been summarised here.Not yet verified

Why this matters: a large offer for sale isn't automatically bad. Early investors have to exit at some point. But when most of the money goes to sellers, ask why they are selling now, and whether the price is set to suit them.

Post-listing performance

Past performance does not predict future returns. Listing-day moves reflect short-term demand and market mood, not the long-term value of the business.
