Borosil Renewables Limited has received a significant credit rating update from India Ratings & Research Private Limited, with the outlook revised to positive from negative while maintaining the IND A rating on its bank loan facilities. The rating action, announced on December 30, 2025, reflects substantial improvements in the company's financial performance and credit metrics.

Rating Action Details

India Ratings has taken comprehensive rating actions on Borosil Renewables' banking facilities:

The rating agency has taken a fully consolidated view of Borosil Renewables and its wholly owned subsidiary, Laxman AG. Notably, the German subsidiary GMB Glasmanufaktur Brandenburg GmbH filed for bankruptcy in July 2025 and ceased to be part of the Borosil group effective July 4, 2025.

Financial Performance Improvement

The outlook revision primarily stems from dramatic improvements in operational profitability and credit metrics during the first half of FY26:

The substantial margin improvement reflects better selling prices following the implementation of anti-dumping duty on solar glass imports from December 2024, effective cost-saving measures, and the de-consolidation of the loss-making German operations.

Key Rating Strengths

India Ratings highlighted several positive factors supporting the rating:

• Consistent Revenue Growth: The company achieved revenue CAGR of over 30.00% during FY22-FY25, with expectations of ₹15,200.00-15,500.00 million in FY26
• Market Leadership: Dominant position with highest installed capacity of 1,000 tonnes per day and first-mover advantage in India's solar glass manufacturing
• Improved Profitability: EBITDA margins surged to 25.00% in 1HFY26 from 4.00% in FY25, supported by price improvements and operational efficiencies
• Strengthened Balance Sheet: Equity fundraise of ₹3,710.00 million completed in October 2025, with additional ₹2,800.00 million expected from warrant conversion by August 2026

Expansion Plans and Future Outlook

Borosil Renewables is expanding its manufacturing capacity by 600 tonnes per day at an estimated cost of ₹9,500.00 million, expected to be operational by end of FY27. The expansion will be largely funded through the recent equity raise and planned warrant conversions, ensuring minimal impact on leverage ratios.

India Ratings expects the company to maintain similar margin levels through 2HFY26 and FY27, supported by continued price improvements and a 10.00% reduction in power expenses from 4QFY26 due to a new captive solar-wind hybrid plant.

Rating Sensitivities

The rating agency outlined clear parameters for future rating actions:

Positive Triggers:

• Sustained improvement in consolidated revenue and EBITDA while maintaining net leverage below 2.00x

Negative Triggers:

• Lower-than-expected revenue growth or operating profitability
• Working capital cycle elongation or significant capex increases leading to net leverage exceeding 2.00x

The positive outlook revision reflects Borosil Renewables' successful operational turnaround and strengthened financial position, positioning the company well for continued growth in India's expanding solar glass market.

Borosil Renewables has informed stock exchanges about the voluntary insolvency filing of its German subsidiary, Geosphere Glassworks GmbH. The Managing Director of Geosphere filed an insolvency application on December 22, 2025, before the insolvency court at Cottbus, Germany.

Insolvency Filing Details

Geosphere Glassworks GmbH, a wholly-owned subsidiary of Borosil Renewables, initiated voluntary insolvency proceedings due to insufficient resources to meet financial obligations. The company was established as a special purpose vehicle to acquire and hold a majority stake in GMB Glasmanufaktur Brandenburg GmbH, which has been undergoing insolvency proceedings since July 2025.

German Bank Subsidy Claim

A German government bank had granted a capital subsidy of EUR 4.81 million to GMB under specific conditions, including assurance from Geosphere to provide necessary support for capital expenditure and business operations. Following GMB's insolvency proceedings, certain subsidy conditions could not be fulfilled, leading the German bank to claim the subsidy amount from Geosphere.

Geosphere responded that GMB's production shutdown resulted from inaction by the European Union and Federal Government of Germany to protect solar PV manufacturing in Europe. The subsidiary cited lack of sufficient resources to honor the German bank's demand as the reason for filing insolvency.

Financial Impact on Borosil Renewables

The company has already accounted for the complete exposure related to its German operations. The financial impact details are presented below:

The entire exposure of Rs. 13,003.09 lakhs in the form of investments and loans (including interest) towards Geosphere has already been provided for and disclosed as an exceptional item in the financial results for the quarter ended June 30, 2025.

No Material Impact Expected

Borosil Renewables has clarified that there is no material impact of the insolvency on the company, as the complete financial exposure has already been accounted for in previous financial statements. The German subsidiary was a non-operating company primarily established to hold the stake in GMB, which was previously the largest producer of solar glass in Europe.

This development follows the company's earlier strategic shift towards focusing on the Indian solar glass market, including plans to increase production capacity by 600 tonnes per day with an investment of Rs. 950.00 crore in domestic operations.
