Despite continued challenges in the sugar and ethanol industry, our focus on operational efficiencies, portfolio diversification and disciplined execution has helped strengthen our business fundamentals. The Bio-based Chemicals business maintained strong momentum, with revenue growing by approximately 39% year-on-year and segment EBITDA increasing by approximately 47% year-on- year. Our earlier debottlenecking initiatives are translating into stronger commercial performance and improved profitability. We continue to pursue further capacity optimization, process improvements and product development to capture opportunities across domestic and international markets. In the integrated sugar and ethanol business, operating conditions remained challenging due to weather-related uncertainties, sugarcane availability and rising feedstock costs. Recent policy restrictions on the diversion of sugarcane juice and B-heavy molasses towards ethanol have added to industry pressures. However, our expanded grain-based distillery capacity provides greater flexibility to optimize operations based on market conditions. Innovation continues to be a key pillar of our long-term strategy. We have secured a US patent for our novel anti-cancer molecule, along with European patents for anti-cancer pharmaceutical compositions and bio-based rubber reinforcement technology. Additionally, we have been granted patents in China and Mexico for our antiviral compounds. Further reinforcing our commitment to manufacturing excellence, we were honoured with the Manufacturing Process Innovator of the Year Award at the FICCI Chemicals and Petrochemicals Awards 2026. Looking ahead, our priorities remain focused on scaling our Bio-based Chemicals portfolio, strengthening our ethanol business in line with India's Biofuel Programme, improving operating efficiencies and enhancing feedstock flexibility. Continued investments in debottlenecking, differentiated technologies and product innovation will drive portfolio diversification, operational resilience and sustainable long-term growth.” Godavari Biorefineries Ltd.
