Commenting on the performance Mr. Narayan Saboo, Chairman and Non Executive said:

“The second quarter of FY2026 marked a period of steady improvement in operational performance for Bigbloc Construction, supported by recovering demand conditions and higher capacity utilisation across plants. Despite an extended monsoon season, construction activity picked up momentum towards the latter part of the quarter, resulting in stronger sales volumes and revenue growth.

Mr. Narayan Sitaram During the second quarter of FY2026, Bigbloc Construction Saboo recorded consolidated Revenue from Operations of Rs. 673 million, a growth of 30.3% year-on-year and 19.5% sequentially.

The strong performance was driven by higher sales volumes, which grew by 43.7% year-on-year and 18.3% quarter-on-quarter, supported by improved capacity utilisation and a gradual recovery in construction activity post-monsoon.

While the prolonged monsoon led to a slower start to the quarter, demand picked up meaningfully towards the end of the period as project execution resumed across key regions. The Company’s capacity utilisation improved to 62% in Q2 FY2026 compared to 53% in the previous quarter, reflecting the healthy pickup in order inflows and operational throughput. In the AAC wall panel business, capacity utilisation also increased to 43% from 36% in the previous quarter, supported by growing awareness and expanding customer acceptance.

On profitability, EBITDA for the quarter was Rs. 19 million with a margin of 2.8%, compared to Rs. 13 million and a margin of 2.3% in Q1 FY2026. The sequential improvement in margins was driven by better capacity utilisation and stable input costs. The Company continues to focus on optimising logistics and improving process efficiency enhance profitability.

For the first half of FY2026, Bigbloc reported consolidated Revenue from Operations of was Rs. 1,237 million, up 19.8% over the same period last year. EBITDA for the half year was Rs. 32 million with a margin of 2.6%.

The broader building materials sector is witnessing gradual improvement supported by sustained government push towards affordable housing and urban infrastructure. Within this environment, demand for sustainable, energy-efficient construction materials such as AAC blocks continues to strengthen.

On the strategic front, the Company remains focused on ramping up utilisation levels across facilities and scaling its AAC wall panel operations. The upcoming commissioning of the construction chemicals facility at Umargaon in the second half of FY2026 will further diversify the product portfolio and strengthen Bigbloc’s position as an integrated green building materials company.

Looking ahead, the medium-term outlook for the building materials sector remains positive, supported by continued government focus on infrastructure, housing, and industrial development. With the monsoon behind us and demand momentum improving, the Company expects higher utilisation levels and improved operating performance in the coming quarters.”
