ReNew Energy (Nasdaq: RNW) sells $600M 6.5% green bonds due 2031

Rhea-AI Filing Summary

ReNew Energy Global reported that it raised USD 600 million through an oversubscribed offering of 6.5% senior secured green bonds due 2031. The bonds were issued via its GIFT City subsidiary, are guaranteed by ReNew entities, and use a security package similar to its 7.95% green bonds due 2026.

Proceeds will primarily redeem $525,000,000 of the higher‑coupon 7.95% Diamond II Bonds, making the transaction debt‑neutral while cutting the interest rate from 7.95% to 6.5% and extending maturity from 2026 to 2031. Investor demand exceeded USD 2 billion, with peak oversubscription of about 3.5x and pricing tightened by 37.5 basis points.

This is described as the first international bond issuance from a GIFT City issuer and is expected to be rated Ba3 by Moody’s and BB- by Fitch. The company highlights that the deal supports interest cost optimization and strengthens its long-term financial profile.

Insights

Credit and capital structure analyst

ReNew refinances $525M of 7.95% notes with a $600M 6.5% green bond due 2031, cutting coupon and extending maturity on a debt‑neutral basis.

The company has issued USD 600 million of 6.5% senior secured green bonds due 2031, mainly to redeem $525,000,000 of existing 7.95% Diamond II Bonds maturing in 2026. Because proceeds are earmarked for redemption, management characterizes this as a debt‑neutral transaction, but with a lower coupon and longer tenor. That combination typically eases near‑term refinancing pressure and reduces ongoing interest expense versus the redeemed bonds.

Demand metrics are strong: peak order books were about 3.5x oversubscribed with over USD 2 billion in indications, allowing pricing to tighten by 37.5 basis points from initial guidance. The bonds are expected to be rated Ba3 by Moody’s and BB- by Fitch, consistent with a sub‑investment‑grade profile but within the range many institutional investors target. The transaction also marks the first international bond from a GIFT City issuer, which the company links to its strategy of using a Global Regional/Corporate Treasury Centre to diversify funding sources.

ReNew Energy Global Plc (“ReNew” or the “Company”) (Nasdaq: RNW, RNWWW), announced that on January 22, 2026, it successfully raised USD 600 million through an oversubscribed offering of 6.5% senior secured green bonds due 2031 (the “green bonds”). The issuance was made through ReNew’s subsidiary in GIFT (Gujarat International Finance Tec-City), ReNew Treasury IFSC Private Limited, a wholly-owned subsidiary of ReNew Private Limited. The green bonds are guaranteed by ReNew and ReNew Private Limited and will be secured by a security and collateral package similar to the 7.95% Senior Secured Green Bonds due 2026 issued on April 28, 2023 by the Company’s wholly-owned subsidiary, Diamond II Limited (the “Diamond II Bonds”), including partial asset security equal to 0.5x and total security cover of 1.0x.

The green bonds were issued in a private offering exempt from the registration requirements of the Securities Act of 1933, as amended (the “Securities Act”), to non-U.S. persons in offshore transactions in accordance with Regulation S under the Securities Act. The green bonds are subject to restrictions on transfer and, unless registered, may only be offered or sold in transactions exempt from or not subject to the registration requirements of the Securities Act and other applicable securities laws.

The green bonds attracted strong demand from institutional investors across Asia, the UK and the US. The transaction was oversubscribed by c.3.5x at its peak, with a total investor demand aggregating in excess of USD 2 billion, resulting in a 37.5 bps tightening from initial price guidance.  

This marks the first-ever international bond issuance from a GIFT City issuer. The green bonds were issued under ReNew’s Green Financing Framework and have received a Second Party Opinion from DNV, an external consultant. Proceeds will be used in accordance with the framework and primarily to redeem $525,000,000 aggregate principal amount of Diamond II Bonds, making this a debt-neutral transaction and resulting in an interest rate reduction from 7.95% to 6.5% and maturity extension from 2026 to 2031. The green bonds are expected to be rated Ba3 by Moody’s and BB- by Fitch.

The issuance underscores ReNew’s diversified funding strategy and its strong access to global capital markets. ReNew’s Group CFO, Kailash Vaswani, said: “This landmark issuance from GIFT City reflects strong global investor confidence in ReNew’s credit and green credentials. The establishment of our Global Regional/Corporate Treasury Centre enhances our funding flexibility and access to diversified pools of capital. This transaction supports interest cost optimization, further strengthening our long-term financial profile.”
