StarBigBloc Building Material, a wholly owned subsidiary of BigBloc Construction Ltd (BSE: 540061), has received shareholder approval to raise funds through an Initial Public Offering (IPO). The move is aimed at unlocking shareholder value, securing growth capital, and potentially enhancing the overall valuation of BigBloc Construction. 

The IPO proposal was approved during the company’s Extraordinary General Meeting (EGM) held on 13th June 2025. The process remains subject to regulatory approvals, market conditions, and other applicable clearances. 

“This is a significant milestone in our growth journey. The IPO will enable StarBigBloc Building Materials Limited to access capital markets, drive next phase of expansion, and solidify its market position across India. This step aligns with our long-term vision to scale efficiently and establish our stronghold in building material sector. The AAC block industry is set to play a pivotal role in India's construction sector, and our company is ready for a significant leap forward,” said Mr Mohit Saboo, Director and Chief Financial Officer, BigBloc Construction Ltd. 

BigBloc Construction, incorporated in 2015, is India’s largest and only listed manufacturer of Aerated Autoclaved Concrete (AAC) blocks, with an annual production capacity of 1.3 million CBM. Its manufacturing footprint spans plants in Gujarat (Kheda, Umargaon, Kapadvanj) and Maharashtra (Wada). In FY25, the company reported revenue from operations of Rs 2.246 billion. 

StarBigBloc Building Material currently operates a plant in Kheda, near Ahmedabad, with an installed capacity of 250,000 cubic metres per annum. This facility caters to the Gujarat market and extends its services to Udaipur in Rajasthan and Indore in Madhya Pradesh. 

In May 2024, StarBigBloc’s Board had approved raising funds via an SME IPO or preferential issue, subject to approvals and market conditions. The company plans to expand its production capacity to over 1.2 million CBM over the next 4–5 years. As part of its growth strategy, it is targeting revenues of Rs 4.28 billion by FY27–28, with a projected EBITDA of Rs 1.25 billion and net profit of Rs 80 crore. 

The company recently secured key approvals for its upcoming Indore project, including Town Planning Clearance (TPC), Land Registration, Gram Panchayat approval, and the Non-Agricultural (NA) order. With these in place, the company is preparing to set up India’s largest greenfield AAC blocks facility, reinforcing its leadership in sustainable building materials. 

In February 2025, StarBigBloc acquired approximately 57,500 sq. metres of land at Gram Nimrani, Tehsil Kasrawad, Khargone district, Madhya Pradesh, for expanding its AAC blocks business. The strategic acquisition aims to strengthen the company’s presence in central India, supporting growing regional demand.
