Issuer Overview

• Adani Transmission Step-One Limited (ATSOL / ADTIN) is related to Adani Energy Solutions Limited (AESL), but the covered debt should be analysed at the ATSOL obligor-group level rather than as a regular unsecured AESL corporate bond.
• The covered bond is XS2080214864, originally USD 500mn 4.25% Senior Secured Notes due 21 May 2036, issued in November 2019. The September 2025 certificate describes it as an amortising 16.5-year instrument with original weighted-average maturity of 10.14 years.
• The September 2025 certificate does not separately disclose the current principal outstanding of the 2036 notes. It shows aggregate USD bonds for both the 2026 and 2036 notes.
• The direct repayment source is the transmission-asset cash flow of the ATSOL obligor group, not AESL consolidated revenue from transmission growth projects, distribution, or smart meters.

Core Credit View

• ATSOL is a secured, amortising, restricted-group transmission infrastructure credit. The core analytical chain is availability of the transmission assets, regulated or contracted tariff recovery, beneficiary collections, account waterfall, DSRA, DSCR, and hedging.
• End-September 2025 metrics support a stable public-information-based view: DSCR was 1.89x, FFO/net debt was 13.50%, FFO cash interest was 2.31x, and receivables over 180 days were zero.
• The cushion is not as thick as pre-March 2024 covenant history might suggest, because AESL was removed from the obligor group and treasury income no longer entered EBITDA/FFO calculations. The post-scope-change metrics should be used for trend assessment.
• Key constraints are high total debt, USD-denominated obligations backed by rupee-denominated revenue, regulatory and collection risk, Adani group headline and market-access risk, unconfirmed current 2036 note balance, unconfirmed post-2026-refinancing debt structure, and lack of full rating-agency reports.

Business and Franchise View

• Company materials identify four existing transmission assets in the ATSOL obligor group: Mundra-Mohindergarh HVDC Line, Mundra-Sami-Dehgam Line, Tiroda-Warora Line, and Tiroda-Aurangabad Line.
• The first two assets are CERC-regulated and the latter two are MERC-regulated. Company materials show licence expiry dates extending beyond the 2036 final maturity and state that certain licences are deemed renewed unless revoked under the Electricity (Amendment) Rules, 2023.
• The main operating support is high availability. The obligor group's average availability remained in the 99% range through FY2025 and the first half of FY2026, with Q1 FY2026 and Q2 FY2026 averages of 99.57% and 99.46%.
• Transmission credit risk is not driven by power generation volume or merchant power prices. It is driven by asset availability, regulated income, tariff orders, recovery of past differences, beneficiary payments, receivable ageing, maintenance, and account controls.

Capital Structure and Structural Points

• The certificate covers the 2026 and 2036 notes under the Common Terms Deed and Amended and Restated Common Terms Deed. IDBI Trusteeship Services Limited is identified as Security Trustee and Madison Pacific Trust Limited as Note Trustee.
• End-September 2025 total debt was INR 68,589mn, including INR 63,762mn of USD bonds and INR 4,827mn of other short-term debt. The USD-bond figure is an aggregate for the 2026 and 2036 notes at the hedged exchange rate.
• The 2036 notes' scheduled amortisation is structurally positive because principal is reduced over time, but each scheduled instalment depends on cash collection, DSRA, hedging, and waterfall operation.
• The full Offering Circular / trust deed still needs review for collateral scope, pari passu ranking, cure periods, distribution restrictions, change of control, events of default, enforcement, and relationship with new debt after the 2026 refinancing.

Liquidity and Funding View

• End-September 2025 cash and cash equivalents were INR 2,485mn, including DSRA of INR 999mn. These balances should not be treated as fully unrestricted cash.
• The certificate states that the liquidity reserve account is not required after restructuring because ATIL, MEGPTCL, and ATSOL have no capex over the next six months. This does not remove future maintenance, restoration, or regulatory upgrade risk.
• Apollo disclosed on 11 March 2026 that ATSOL Global IFSC Limited issued USD 500mn of investment-grade senior secured private placement notes, mainly intended to refinance notes maturing in late 2026. This may reduce near-term maturity-concentration risk, but completion, collateral sharing, ranking, and covenant impact for the 2036 notes remain unconfirmed.
• FX and hedge risk are recurring issues. The certificate provides a hedged exchange rate under principal-only swaps / cross-currency swaps, but hedge maturity, counterparties, collateral posting, termination cost, and renewal capacity through 2036 require confirmation.

Credit Strengths

• Existing operational transmission assets with high availability.
• Regulated or contracted revenue framework through CERC and MERC-regulated assets.
• Secured restricted-group structure with trustees, account waterfall, DSRA, covenant metrics, and no-default certification as of September 2025.
• Amortising 2036 notes reduce final bullet refinancing risk relative to a conventional bullet bond.
• Disclosed 2026 refinancing-related private placement may reduce near-term maturity pressure if completed and structurally aligned with existing noteholders.

Credit Weaknesses

• Current standalone principal amount, price, yield, spread, WAL, and liquidity of the 2036 notes remain unconfirmed.
• Aggregate USD bonds include both the 2026 and 2036 notes, so the 2036 notes cannot be analysed from the certificate balance alone.
• Post-refinancing debt-service schedule and collateral/ranking relationship between the new notes and existing 2036 notes remain unresolved.
• Revenue is primarily rupee-denominated while debt is USD-denominated, requiring effective long-term hedging.
• DSCR is stable but not extremely high after the obligor-group scope change.
• Adani group governance, litigation, funding-access, and investor-sentiment risks can affect ratings and spreads even if the direct repayment source is ring-fenced.

Rating Watchpoints

• AESL March 2026 results materials show Fitch BBB-/Stable, Moody's Baa3/Stable, and S&P BBB-/Stable for ATSOL international bonds.
• AESL's Q3 FY26 media release dated 2026-01-22 states that Moody's affirmed Baa3 senior secured ratings for AESL, AEML, ATSOL, and others and changed the outlook to Stable.
• The latest full reports from Fitch, Moody's, and S&P were not reviewed in the current memory set. Upgrade/downgrade sensitivities, support assessment, country-risk treatment, and covenant analysis remain unverified.

Recurring Analytical Cautions

• Do not conflate ATSOL's obligor-group cash flows with AESL consolidated growth in transmission, distribution, and smart metering.
• Do not compare pre- and post-March 2024 covenant metrics without adjusting for the removal of AESL from the obligor group.
• Do not treat secured status as equivalent to full recovery. Transmission assets derive value from regulated revenue, licences, availability, and business continuity, not simple liquidation.
• Do not state the current 2036 note principal outstanding unless confirmed outside the aggregate USD-bond disclosure.
• Distinguish refinancing of the 2026 notes from the risk and terms of the 2036 notes.

Ongoing Follow-Up Items

• Obtain the March 2026 or FY2026 ATSOL obligor-group compliance certificate and compare DSCR, FFO/net debt, FFO cash interest, receivables ageing, DSRA, total debt, and availability with September 2025.
• Confirm the actual repayment or refinancing completion of the 2026 notes after the March 2026 Apollo-related private placement.
• Review the post-refinancing debt-service schedule, collateral sharing, ranking, additional-debt treatment, and covenant effect of the new notes relative to the 2036 notes.
• Confirm current outstanding principal, scheduled amortisation profile, WAL, price, yield, spread, and liquidity of XS2080214864 / ADTIN 2036 on a standalone basis.
• Track asset availability by line, especially any period where availability falls below stipulated levels or where outages affect incentives or tariff recovery.
• Monitor receivables ageing, particularly any emergence of balances over 180 days, growth in the 121-180 day bucket, working-capital borrowings, and cash conversion of past revenue gaps.
• Monitor hedge maturity, counterparties, collateral posting, termination costs, and ability to maintain FX and interest-rate hedging through 2036.

Unresolved Issues and Items to Check Next Time

• Full 2019 Offering Circular and trust deed provisions for the 2036 notes remain unreviewed, including collateral package, guarantees, pari passu relationships, cure periods, change of control, events of default, distribution restrictions, and enforcement.
• Current principal outstanding of the 2036 notes is unconfirmed because the September 2025 certificate presents aggregate USD bonds for both the 2026 and 2036 notes.
• The contractual relationship between ATSOL Global IFSC Limited's new private-placement notes and the existing ATSOL obligor-group notes is unconfirmed.
• Latest full Fitch, Moody's, and S&P reports have not been obtained.
• Market price, spread, OAS/Z-spread, G-spread, and trading liquidity are unconfirmed.

Analytical Cautions

• Start with the ATSOL obligor group's transmission cash flows, not AESL consolidated growth. AESL is sponsor context and operating platform, not the direct repayment source for the 2036 notes.
• Use post-March 2024 covenant metrics as the main trend base because AESL's removal from the obligor group changed the calculation scope.
• Treat DSCR of 1.89x as supportive but not a very thick cushion. It depends on continued high availability, tariff recovery, receivable collection, hedging, and account controls.
• Receivables over 180 days were zero at September 2025, but total receivables and the 121-180 day bucket still require monitoring as leading indicators.
• The Apollo-related refinancing development is positive only if actual repayment, ranking, collateral, and covenant treatment are confirmed.
• Security is meaningful, but normal-course cash collection and account-waterfall performance are more important than assuming asset-liquidation recovery.

Report Wording Cautions

• Use "ATSOL obligor group" and "restricted-group transmission-asset cash flows" rather than implying a normal AESL unsecured corporate obligation.
• When mentioning ratings, specify that full rating reports were not reviewed and that company materials or releases are the confirmed route currently in memory.
• Avoid stating the standalone 2036 note balance unless sourced from trustee, clearing-system, market-data, or official updated disclosure.
• Avoid saying that 2026 refinancing is complete or beneficial for 2036 noteholders unless documentation confirms the actual repayment and structural treatment.

Follow-Up on Management Strategy, Investment Plans, and Financial Policy

• Check whether AESL or Adani group financing strategy changes the debt perimeter, collateral sharing, or additional-debt capacity of ATSOL.
• Monitor whether transmission asset capex, maintenance, regulatory upgrades, or accident restoration needs alter the no-near-term-capex statement in the September 2025 certificate.
• Track whether distributions, related-party transactions, or cash movement after debt service reduce retained protection for 2036 noteholders.

Items to Check for Ratings and Bond Investors

• Latest ATSOL compliance certificate and post-refinancing debt schedule.
• Full Fitch, Moody's, and S&P reports with rating sensitivities.
• SGX/Offering Circular/trust deed materials for the 2036 notes.
• Trustee or noteholder reports for DSRA, account waterfall, distributions, waivers, amendments, and default status.
• Market-data provider or dealer information for current outstanding amount, price, spread, WAL, and liquidity.
