For the financial year 2025, Bigbloc Construction reported consolidated Revenue from Operations of Rs. 2,246 Mn, a decline of 7.6% YoY. The decrease in revenue was primarily attributed to a slowdown in India’s construction sector, a key demand driver for our products, which experienced a period of deceleration due to several external factors. General elections in the country led to delays in government-led infrastructure projects, while prolonged monsoon conditions disrupted site operations, logistics, and supply chains. These factors collectively impacted order flows, site execution and on-ground activity, particularly in core geographies such as Maharashtra and Gujarat.

Operationally, the consolidated capacity utilisation for the year stood at 59%. The lower utilisation was largely due to the planned shutdown and subsequent technology upgrade at the Umargaon plant. This also

impacted the EBITDA, which stood at Rs. 292 million for FY2025. However, trial operations resumed in October 2024, and the plant is now gradually scaling up to optimal utilisation levels. The upgrades are expected to enhance long-term efficiency and product quality. Despite these operational challenges, the Company maintained a stable Net Debt to EBITDA ratio of 1.3x in FY2025.

Strategically, the Company completed the Phase 2 expansion of its Wada facility under its wholly owned subsidiary, Bigbloc Building Elements. With this expansion, Bigbloc's total installed capacity reached 13 lakh cubic meters per annum, positioning it among the largest AAC block manufacturers in the country.

During the year, the joint venture company SIAM Cement BigBloc Construction Technologies launched India's first AAC Wall Plant in Kheda, Gujarat. The plant received an order from Tata Projects for AAC wall panels at Micron’s semiconductor unit in Sanand, Gujarat. This marks an important milestone in introducing large-format AAC wall panels to the Indian market.

Further strengthening its portfolio diversification, the Company ventured into the manufacturing of construction chemicals through its subsidiary at the Umargaon facility. This strategic move broadens Bigbloc’s offerings and enables entry into fast-growing segments within the building materials industry.

On the sustainability front, the total installed solar power capacity across Bigbloc and its subsidiaries now stands at 2,375 kW. With this initiative, the Company is now meeting approximately 22% of its power requirements through renewable energy, thereby aligning operations with its long-term ESG goals.

Looking ahead, in line with its vision for long-term expansion, the Company, through its subsidiary Starbigbloc Building Material, has acquired land in Madhya Pradesh to expand its AAC Blocks business in central India. Furthermore, with the commissioning of the upgraded Umargaon plant and the stabilization of the new AAC wall panel operations, the Company is well-positioned to capitalize on the recovery in construction activity.
