ACME Solar Holdings Ltd. sees a credit rating action

Refinancing Quantum and Projected Annual Interest Savings

ACME Solar Holdings Ltd. refinanced Rs 2,147 Crores of debt, redeeming offshore dollar bonds through long-term domestic refinancing from the National Bank for Financing Infrastructure and Development (NaBFID) across 12 Special Purpose Vehicles (SPVs) ^[1], ^[2], ^[3].

A 150 basis points (1.50%) reduction in interest rate across the refinanced facilities translates into:

• Projected Annual Interest Savings: Rs 32.21 Crores per annum (derived: Rs 2,147 Crores refinanced debt ^[1] multiplied by 1.50% rate reduction ^[4]).
• Quarterly Cash Interest Relief: Rs 8.05 Crores per quarter (derived: Rs 32.21 Crores annual savings divided by 4).

Translation Relative to Reported Quarterly Finance Costs

In the most recent reported quarterly results (Q4 FY26), ACME Solar reported consolidated finance costs of Rs 337.48 Crores ^[5] (and standalone finance costs of Rs 99.61 Crores ^[6]).

Key Financial & Operational Implications

• Quarterly Run-Rate Relief: The quarterly savings of Rs 8.05 Crores reduces the consolidated quarterly interest expense baseline of Rs 337.48 Crores ^[5] by 2.39% (derived).
• Earnings Accretion: Assuming stable operating performance, the full Rs 32.21 Crores annual interest savings flows directly into Profit Before Tax (PBT). Relative to reported Q4 FY26 consolidated PBT of Rs 189.96 Crores ^[8] (an annualized PBT run-rate of Rs 759.84 Crores derived from Rs 189.96 Cr x 4), the refinancing provides a 4.24% boost to annualized profit before tax (derived).
• Capital Structure & FX De-risking: Replacing high-cost offshore bonds with domestic long-term debt eliminates currency hedging friction, improves debt service coverage ratios (DSCR), and aligns long-duration infrastructure project cash flows with domestic debt tenure ^[4], ^[3].

ACME Solar’s domestic refinancing fully replaces its offshore dollar debt with a long-term rupee-denominated loan, substantially eliminating foreign currency fluctuation risk and lowering overall borrowing costs ^[9].

Comparison of Debt Terms

Impact on Foreign Currency Fluctuation Risk

This refinancing materially and favorably alters ACME Solar's risk profile regarding foreign exchange exposure:

• Elimination of FX Exposure: Servicing USD-denominated bonds subjected the company to rupee depreciation risks against the US dollar. Replacing them with an INR-denominated domestic loan from NaBFID removes principal and coupon FX translation exposure for this tranche ^[9].
• Savings on Hedging Costs: Because renewable energy companies historically incurred substantial hedging costs to protect against dollar volatility, shifting to local currency debt avoids these auxiliary derivative and hedging expenses ^[10].
• Cash Flow Alignment: Project cash flows are generated in Indian Rupees via domestic PPAs with central and state counterparties. The new rupee-denominated debt structure perfectly matches the currency of the cash-flow generation, eliminating asset-liability currency mismatch ^[9].

ACME Solar’s post-refinancing cost of debt for the 450 MW Restricted Group (RG) portfolio sits in the 8.0% to 8.50% range ^[10], reflecting a 150 basis point (bps) reduction achieved via domestic refinancing from NaBFID ^[9]. This aligns closely with the weighted average cost of debt (WACD) for ACME’s broader operational solar asset base, which was estimated at 8.45% as of December 31, 2025 (also down 150 bps year-over-year) ^[11].

Portfolio Refinancing vs. Broader Operational WACD

• Specific 450 MW RG Portfolio: ACME refinanced INR 2,147 crore of existing Non-Convertible Debentures (NCDs) and offshore dollar bonds across 12 operational SPVs through a long-term facility from the National Bank for Financing Infrastructure and Development (NaBFID) ^[9]. The resulting 150 bps cost reduction brought the borrowing rate down to 8.0%–8.50% ^[10], replacing legacy dollar bonds that carried a 4.7% coupon but traded at higher yields to maturity alongside steep hedging costs ^[10].
• Broader Operational and Total WACD: According to credit rating assessments, ACME's WACD across its overall outstanding borrowings (combining operational and under-construction projects) stands at ~8.6% p.a. ^[11]. The 450 MW RG portfolio's post-refinancing rate is therefore slightly below or at parity with the broader operational WACD of 8.45% ^[11], supported by a provisional AA- rating from CARE ratings that reflects strong operational cash flows and central utility offtaker ties (56% with SECI and NTPC) ^[9].

Alignment with Renewable IPP Peers and Market Benchmarks

• Shift to Domestic Debt: Across the broader Indian renewable IPP sector, rising global bond yields, geopolitical volatility, and expensive currency hedging costs have prompted developers to pivot away from offshore dollar-denominated bonds toward domestic institutional lenders (such as NaBFID, PFC, and REC) ^[10].
• Peer Benchmark Gap: Comprehensive, like-for-like WACD breakdowns for individual listed peers in the comparison set (such as SJVN, NLC India, Nava, Clean Max, and JPPOWER) are not explicitly disclosed in standardized quarterly filings, representing a cross-sector reporting disclosure gap. However, broader sector analysis (such as IEEFA reports) indicates that domestic financing terms for top-tier renewable portfolios typically cluster in the 8.0% to 9.0% band depending on project asset quality, offtaker mix, and credit ratings.

Implications and Risks

• Balance Sheet & Currency De-risking: Substituting offshore dollar debt with domestic rupee-denominated credit eliminates currency depreciation vulnerability—a key risk for dollar-denominated module capex—and stabilizes project cash flows under fixed-tariff Power Purchase Agreements (PPAs) ^[3].
• Interest Rate Sensitivity: Despite successful refinancing and lower borrowing costs, ACME operates with high financial leverage (consolidated gross debt-to-equity of 3.75x in Q4 FY26 ^[12] and total consolidated debt of INR 18,988 Crores ^[13]), leaving debt coverage metrics sensitive to domestic interest rate movements ^[11].
