Risks Investors Need To Consider

While this appears to be a promising IPO, the company’s Red Herring Prospectus (RHP) highlights some concerns.

• Customer concentration: The plan is dependent on just a small customer base, with 99% of FY25 revenue concentrated in the top ten customers
• Stress on working capital: The company’s receivables were at ₹6,049.99 lakh when its borrowings were at ₹7,855.19 lakh
• Geographical concentration: The company is mostly dependent on the state of Gujarat, with almost 98% of revenue coming from this location
• Reliance on suppliers: Almost 67% of the Company’s suppliers were dependent on the 10 biggest suppliers for their purchases
• Litigations: The company is involved in 8 cases where there are claims totaling ₹149.88 lakh
• Compliance issues: The company has had filing delays for the GST and professional taxes in the past.

The IPO provides an opportunity for investors looking to gain exposure to a growing area in India – the country’s infrastructure and engineering sector. However, given the previously discussed risks, cautious optimism is likely the best approach.
