Dates for the Bonfiglioli Transmissions IPO are tentative and can change, so check the final notice. Some sources show a face value of Rs 1 and others Rs 10, and one source shows the offer for sale at 4,69,98,959 shares worth about Rs 2,754 crore, which does not match the Rs 2,534 crore issue size. I use the figures that agree across most sources.

Risk: Because the Bonfiglioli Transmissions IPO is entirely an offer for sale, the company receives nothing, and the price band does not guarantee any listing outcome.

Pros of the Bonfiglioli Transmissions IPO

Strength	Detail
Market position	A company-commissioned report calls it India's largest maker of gearboxes below 15 kNm by revenue
Range	More than 11,800 products as of 31 December 2025
Spread of demand	No single end-user industry was above 10% of industry and automation revenue
Customer ties	Seven of the top 10 OEM customers have been with it for over 10 years
Parent	Bonfiglioli S.p.A. reported group revenue of 1,172.94 million euros for 2025
Profit growth	CY2025 profit up about 22% to 24% (my calculation); six month profit up about 29%
Return ratio	Return on net worth of 23.96% in CY2025

Market share claims in the Bonfiglioli Transmissions IPO papers come from a report commissioned by the company, which puts its share at about 25% in low and medium duty gear motors, and the wind drive share is shown as 67.9% in one source and 68.3% in another. Treat them as company-linked views, not independent facts.

Profit growth for CY2025 is 24.1% using a CY2024 profit of Rs 191.60 crore and 21.9% using Rs 195.16 crore, because sources differ on the earlier figure.

Risk: The strengths of the Bonfiglioli Transmissions IPO rest partly on company-supplied data, so check the prospectus for the original tables.

Cons of the Bonfiglioli Transmissions IPO

Concern	Detail
No proceeds	Offer for sale only, so no money goes to the company
Valuation	About 46.3 times CY2025 earnings at the upper band (my calculation)
Customer concentration	Top 10 OEM customers were 31.72% of revenue in the first half of 2026 and 36.60% in CY2025
Supplier concentration	Top 10 suppliers were 40.84% of purchases; the largest is a related party at 15.53%
Parent licence	Non-exclusive licence for one year with automatic renewal, at a fee of 6% of sales of specified products
Credit terms	Most sales on credit of 30 to 120 days and some up to 240 days
Cash conversion	Operating cash flow was about 79% of profit in CY2025 (my calculation)
Cyclical demand	Depends on customer capital spending in automation, off-highway and wind

For the Bonfiglioli Transmissions IPO, the related party supplier share is 15.53% in one source and 19.98% in another, and no definitive supply agreements are reported. The technology and trademark licence from the parent can be affected if the group relationship changes.

Risk: The Bonfiglioli Transmissions IPO carries a premium multiple, so slower growth or a weaker order flow could hurt the share after listing.

Bonfiglioli Transmissions IPO Financials and Valuation

Item	CY2025	CY2024	CY2023
Revenue (Rs crore)	2,013.53	1,854.18	1,687.30
EBITDA (Rs crore)	370.77	295.07	243.80
Profit after tax (Rs crore)	237.87	191.60	148.40
Diluted EPS (Rs)	12.65	10.08	7.57
Return on net worth	23.96%	22.25%	18.30%

The Bonfiglioli Transmissions IPO financials are for years ended 31 December, and some sources label them FY25, FY24 and FY23. Revenue grew about 8.6% in CY2025, the EBITDA margin was about 18.4% and the profit margin about 11.8% (my calculations). For the six months to 30 June 2026, profit was Rs 148.58 crore against Rs 114.97 crore a year earlier, about 29% higher (my calculation). One source shows six month figures under an FY26 label and the quarterly and annual numbers look mixed up, so rely on the prospectus.

Peer	P/E (source A)	P/E (source B)
Bonfiglioli Transmissions at upper band	About 46.3 (my calculation)	About 46.3
Elecon Engineering	31.63	26.02
Shanthi Gears	63.39	37.58
Schaeffler India	53.74	64.54
Timken India	57.66	50.49

Peer multiples differ between the two sources because they are taken on different dates. On either set, the Bonfiglioli Transmissions IPO is above Elecon Engineering, the closest peer by product, and below some of the larger bearing and transmission names.

Grey market premium (GMP) is an unofficial, unregulated indicator for the Bonfiglioli Transmissions IPO that is not endorsed by SEBI, NSE, or BSE. Investors looking for indicative GMP data can go through other relevant sources, though such figures should never be the sole basis for an investment decision.

Risk: Peer multiples change daily, so recheck them on the bidding day before judging the Bonfiglioli Transmissions IPO as expensive or fair.
