AI summary

Rossari Biotech has commissioned a 20,000 MTPA capacity expansion at its Dahej facility, effective September 26, 2025, taking the company's total installed capacity to 152,500 MTPA. At its material subsidiary Unitop Chemicals, 15,000 MTPA of ethoxylation capacity (the first phase of a planned 30,000 MTPA expansion) has also been commissioned at the Dahej facility. Unitop's total ethoxylation capacity now stands at 51,000 MTPA, with the second phase of expansion expected to be completed by Q3 FY26.

Likely market impact

Positive for shareholders — the additions expand production headroom for both Rossari and its subsidiary, supporting future revenue growth, though near-term financial impact will depend on how quickly the new capacity is utilised.
