M&B Engineering IPO: What works and what doesn't

Summary: Thinking of applying for the M&B Engineering IPO? The pre-engineered buildings specialist has delivered strong profits in recent years but revenue growth has been far more modest. And there remain other risks that investors should not overlook. Find them in the story below.

M&B Engineering, one of India’s leading players in the pre-engineered buildings (PEB) industry, is opening its IPO for subscription from July 30 to August 1, 2025.

We bring you a quick breakdown of the business, its past track record and key strengths and weaknesses to help you make an informed decision:

What the company does

M&B Engineering operates through two divisions. Phenix, its larger segment contributing three-fourths of its revenue, delivers complete PEB solutions—design, fabrication and assembly. These factory-made steel structures are shipped in parts and erected on-site, a model that trims construction time and cost.

Proflex, the smaller segment, focuses on roofing solutions, particularly self-supported steel roofs for warehouses and industrial sheds.

Past track record and valuation

M&B’s numbers tell a story of profitability outpacing revenue. From FY23-25, revenue has grown at a modest 6 per cent per annum, while net profit surged 53 per cent annually, helped by improving margins. Return ratios have been healthy too, with ROE averaging 23 per cent and ROCE at 20 per cent over this period.

At the upper price band of Rs 385, the company is asking for a valuation of 29 times earnings and 4 times book value. That price-to-book multiple is a notch higher than the industry’s average of about 3x, though the P/E multiple broadly matches peers.

The good

For now, the company has a strong pipeline of business. As of June 30, its order book stood at Rs 843 crore, giving it solid visibility for coming quarters. The cost efficiency that PEBs offer is another key advantage: they are often 15–35 per cent cheaper than traditional construction and can be completed faster, while offering greater quality control.

M&B’s integrated model, covering everything from design and fabrication to on-site erection, makes it a one-stop partner for large industrial clients. Over time, it has built sticky relationships with marquee names such as Adani Group, Tata Advanced Systems and AIA Engineering, some stretching back 15 years. These factors provide stability even during tougher phases of the cycle.

The bad

The story has its vulnerabilities. More than half of FY25 revenue came from just 10 customer groups, which leaves M&B exposed if even one of them cuts back. Its working capital cycle is also high at 106 days primarily due to inventory holding that stretches to nearly four months. This stockpiling is necessary to quote competitive prices, as contracts lack raw material price variation clauses but it ties up significant capital and exposes the company to inventory obsolescence.

Finally, like most businesses linked to infrastructure spending, M&B’s fortunes are tied to the investment cycle. A slowdown in capital expenditure can quickly choke order flows and margins.

Where will the IPO money go?

Of the Rs 275 crore being raised, Rs 131 crore will go towards purchasing equipment, machinery, solar rooftop grids and transport vehicles to enhance its manufacturing facilities. Additionally, Rs 59 crore will be used to repay existing borrowings.

So, should you subscribe to M&B Engineering IPO?

The pre-engineered buildings industry is growing and M&B has the track record and relationships to benefit. But IPOs come with scant operating history in the public markets and little clarity on how a company will perform once listed. 

It's wiser to observe how a stock behaves post-listing and assess it with a few quarters of performance behind it.
