Rationale While arriving at the rating for the commercial paper programme of Solar Industries India Limited (SIIL/the company), ICRA has taken a consolidated view of SIIL and its wholly-owned subsidiary, Solar Defence and Aerospace Limited (SDAL, rated [ICRA]A1+). SIIL, along with this subsidiaries, associates and JVs, is being referred to as the Solar Group/the Group. Material Event On September 14, 2026, SIIL announced that its wholly-owned step-down subsidiary, Solar SA Investments Proprietary Limited, had entered into definitive agreements to acquire the entire shareholding of South Africa-based Omnia Holdings Limited (Omnia) for a consideration of around $1.35 billion. The proposed transaction remains subject to the receipt of requisite regulatory and shareholder approvals and the fulfilment of customary closing conditions. Impact of Material Event Omnia is an established diversified chemicals group with operations across the mining, agriculture and chemicals sectors and a presence across multiple countries. Its mining business includes capabilities across bulk explosives, electronic initiation systems, digital blasting solutions and mining chemicals. The proposed acquisition is expected to significantly enhance the Solar Group’s international scale and geographical diversification, particularly in the mining explosives business. Omnia’s integrated ammonium nitrate and nitric acid manufacturing facilities are also expected to strengthen the Group’s backward integration, raw material security and cost competitiveness. The acquisition is proposed to be funded through a mix of debt and internal accruals of the group however, the final funding structure is yet to be finalised. ICRA will evaluate the impact of the transaction on the company’s credit profile once greater clarity emerges on the amount and terms of the acquisition debt. Although no acquisition-related borrowings are currently proposed at SIIL’s standalone level, the transaction is expected to involve financial commitments and corporate guarantees from entities within the Group. Besides enhancing the Solar Group’s consolidated scale of operations, profitability and diversification, the proposed acquisition is expected to result in a significant increase in the Group’s consolidated debt levels (including Omnia Holdings). ICRA takes note of the management’s stated intent to maintain the consolidated net debt/OPBDITA below 2.0 times, supported by the combined operating cash flows of SIIL and Omnia. Nevertheless, the ability of the combined entity to achieve the anticipated earnings, generate adequate cash accruals and progressively deleverage, while maintaining an adequate liquidity position, will remain a key monitorable. The transaction is expected to close after the receipt of the requisite statutory and shareholder approvals, and greater clarity on the final funding structure and the resultant credit metrics is expected to emerge closer to its completion which is expected in H1 of CY2027. www.icra.in 1 Sensitivity Label : Public Page | The acquisition is expected to provide strategic benefits through an enlarged geographical presence, a broader product portfolio, increased scale in the international mining explosives business and potential operating synergies. However, the benefits from the combined scale and operational integration are expected to accrue over the medium term and will remain subject to the timely completion of the transaction and successful integration of Omnia’s operations. The final financing structure, the extent of financial commitments and guarantees from the Solar Group, the resultant consolidated leverage and coverage metrics and the pace of deleveraging will remain the key monitorables. The outstanding rating continues to factor in the Solar Group’s established market position in the domestic industrial explosives industry, its diversified geographical presence, strong operating performance and the increasing contribution from the defence business. The Group benefits from its large manufacturing infrastructure, integrated operations, established relationships with customers across the mining and infrastructure sectors and healthy order book. The rating also factors in the Group’s strong liquidity position and financial flexibility. ICRA will continue to monitor the developments relating to the proposed acquisition and its impact on the business and financial risk profiles of the Solar Group.
