HA Sustainable Infrastructure Capital, Inc., the climate investment firm long known as Hannon Armstrong, has completed the sale of $500 million in aggregate principal amount of its 7.850 percent Green Junior Subordinated Notes due 2057. The underwriting agreement is dated November 9, 2026 and was filed with the Securities and Exchange Commission as an exhibit to the company’s Form 8-K on November 13.
Mizuho Securities USA, BofA Securities, Goldman Sachs and Truist Securities acted as representatives of the underwriters. The notes are issued under the company’s base indenture dated June 24, 2025, with U.S. Bank as trustee, and carry the guarantors named in that indenture. Junior subordinated notes sit low in the capital structure, above equity but below senior debt, and issuers use them to raise long-dated capital that rating agencies treat in part as equity-like.
The filing closes a gap this site flagged yesterday. The offering first appeared as a 424B5 prospectus supplement on November 12, but the pool record available then did not carry a verified principal amount, so the item was held rather than written from a partial record. The 8-K exhibit now supplies the amount, the coupon and the maturity from the issuer’s own document: $500 million, 7.850 percent, due 2057.
HASI finances and manages investments in energy efficiency, renewable energy and other sustainable infrastructure. A 30 year green-labelled hybrid gives it permanent-style capital matched against the long lives of the assets on its balance sheet, at a coupon that reflects both subordination and the current level of long-term interest rates.
