Bonfiglioli Transmissions IPO 2026: Price, Financials & Review

India’s manufacturing story often focuses on automobiles, construction equipment and wind turbines. But behind these machines are companies that make the components enabling them to function.

Bonfiglioli Transmissions is one such company; it manufactures gearboxes, gear motors and drive systems used across industries, giving investors exposure to industrial automation, infrastructure and renewable energy through its ₹2,533.66 crore IPO.

But does the company’s business strength translate into an attractive investment opportunity? Let’s look at its financial performance, growth prospects and IPO valuation to understand whether the asking price is justified.

For key details such as the IPO opening and closing dates, price band and lot size, refer to the table below. 

Bonfiglioli Transmissions IPO is entirely an offer for sale (OFS) by the promoter, meaning the proceeds will go to the selling shareholder rather than the company to fund its expansion.  

Imagine a wind turbine, a conveyor belt or a construction machine. Each requires systems that control movement, speed and torque.

Bonfiglioli manufactures the transmission and drive solutions that help these machines operate.

Its business serves three major verticals:

• Industry & Automation: Gearboxes and drive systems used in manufacturing, material handling and industrial machinery.

   

• Off-Highway Mobility: Transmission solutions for construction, agricultural and other heavy equipment.

   

• Wind: Gearboxes and related solutions used in wind-energy applications.

It operates three separate manufacturing facilities located in Thirumudivakkam, Mannur, and Talegaon to support its production needs. A major portion of its revenue is generated by co-engineering custom products directly with its customers. Furthermore, the business operates under a license agreement with its corporate promoter, granting it the right to manufacture and sell products utilizing the promoter’s proprietary technology, designs, and trademarks.

This claim relates to a defined product category, not every type of gearbox manufactured in India. 

H1 CY2026 revenue mix 

Industrial automation contributes the largest share, but the company also has meaningful exposure to construction equipment and wind energy.

That diversification is useful, although all three businesses remain sensitive to industrial investment cycles.

Bonfiglioli's financials show steady revenue growth, improving profitability and strong capital efficiency.

• Revenue Growth: Revenue increased 8.6% in CY2025, indicating steady business expansion.

   

• Profitability: PAT grew 24.2% in CY2025, significantly faster than revenue, reflecting improving profitability.

   

• EBITDA Margin: The margin improved from 15.91% in CY2024 to 18.41% in CY2025 and 19.78% in H1 CY2026. These margins exclude other income.

   

• Capital Efficiency: ROCE improved to 34.05% in CY2025 from 30.05% in CY2024, indicating more efficient use of capital.

Bonfiglioli's profits are growing faster than its revenue, supported by improving operating margins. The key question is whether this performance can be sustained. 

Bonfiglioli's improving profitability is encouraging, but is the IPO reasonably priced?

• P/E Ratio: At ₹586, the IPO is valued at 46.3× CY2025 earnings, based on EPS of ₹12.65. This means investors are paying ₹46.30 for every ₹1 of annual earnings.

   

• P/B Ratio: At ₹586, the IPO trades at 10.65× book value, based on June 2026 NAV of ₹55.02 per share.

   

• Peer Comparison: The cited peer P/E range is 31.6×–63.4×. Bonfiglioli's 46.3× multiple falls within this range, although differences in business mix and profitability matter.

Bonfiglioli commands a premium valuation, supported by improving margins and strong capital efficiency. Whether that premium is justified will depend on its ability to sustain earnings growth.

• Industrial Slowdown: Demand depends on manufacturing, infrastructure and wind-energy investments. A slowdown could impact orders and revenue.

   

• Supplier Dependence: Bonfiglioli Riduttori S.p.A., a group company, accounted for 15.18% of CY2025 raw-material purchases. Supply disruptions could affect operations.

   

• Working Capital: The cash conversion cycle increased from 83 days in CY2024 to 94 days in H1 CY2026, indicating more capital tied up in operations.

   

• Premium Valuation: At 10.65× June 2026 book value, the IPO leaves limited room for disappointment if growth or profitability slows. 

Bonfiglioli Transmissions has several attractive characteristics, including an established industrial business, diversified end markets, improving margins and strong capital efficiency. Its exposure to automation, infrastructure and wind energy also positions it to benefit from potential long-term growth in these sectors.

However, the IPO is entirely an offer for sale (OFS), meaning the company will not receive any proceeds from the issue. Additionally, the valuation leaves limited room for error if growth or profitability falls short of expectations.
