8-K: HA Sustainable Infrastructure Capital Secures $1 Billion in Green Senior Unsecured Notes for Project Investment and Debt Refinancing

HA Sustainable Infrastructure Capital, Inc. has successfully issued $1 billion in new green senior unsecured notes across two series, maturing in 2031 and 2035, with proceeds earmarked for green project investments and debt refinancing.

Summary

• HA Sustainable Infrastructure Capital, Inc. (HASI) issued a total of $1 billion in new Green Senior Unsecured Notes on June 24, 2025.
• This issuance comprises $600,000,000 aggregate principal amount of 6.150% Green Senior Unsecured Notes due 2031 and $400,000,000 aggregate principal amount of 6.750% Green Senior Unsecured Notes due 2035.
• Interest on both series of Notes will accrue from June 24, 2025, and will be payable semi-annually in arrears on January 15 and July 15 of each year, commencing on January 15, 2026.
• The net proceeds from the offering are intended to fund new and/or existing eligible green projects, including those with disbursements made during the twelve months preceding the issue date and those to be made within two years following the issue date.
• Additionally, proceeds will be used to fund previously announced cash tender offers for a portion of the Offerors' 3.375% Senior Notes due 2026 and 8.00% Green Senior Unsecured Notes due 2027, including related accrued interest, premiums, fees, and expenses.
• A portion of the proceeds will also temporarily repay outstanding borrowings under the Company's unsecured revolving credit facility and commercial paper program.
• The Notes are senior unsecured obligations of the Issuer and are guaranteed by key subsidiaries, including Hannon Armstrong Sustainable Infrastructure, L.P., Hannon Armstrong Capital, LLC, HAT Holdings I LLC, HAT Holdings II LLC, HAC Holdings I LLC, and HAC Holdings II LLC.
• The Notes rank pari passu with the Issuer's existing and future senior unsecured indebtedness and guarantees, but are effectively subordinated to secured indebtedness and liabilities of non-guarantor subsidiaries.
• The Indenture includes provisions for optional redemption by the Company, with make-whole premiums applicable for redemptions prior to specific 'Par Call Dates' (December 15, 2030, for 2031 Notes; April 15, 2035, for 2035 Notes).
• A Change of Control Repurchase Event (Change of Control combined with a Below Investment Grade Rating Event) would require the Issuer to offer to repurchase outstanding Notes at 101% of the principal amount plus accrued interest.

Sentiment

Score: 7

Explanation: The issuance of $1 billion in green notes is a positive development for the company, securing significant capital for strategic investments and debt management. While the interest rates are higher than some existing debt, they are reasonable for current market conditions and the 'green' designation adds appeal. The defined use of proceeds for sustainable projects is also a strong positive. The standard covenants and default provisions are typical for such debt instruments.

Positives

• Successful issuance of $1 billion in new debt demonstrates strong market access and investor confidence in HA Sustainable Infrastructure Capital, Inc.
• The designation of the notes as 'Green Senior Unsecured Notes' aligns with the company's focus on sustainable infrastructure and appeals to the growing ESG investment market.
• The use of proceeds for eligible green projects supports the company's core business strategy and contributes to environmental sustainability.
• Refinancing existing debt allows the company to manage its capital structure, potentially optimizing its debt profile and extending maturities.

Negatives

• The interest rates of 6.150% and 6.750% for the new notes represent a relatively high cost of debt, especially compared to the 3.375% notes being refinanced, indicating a higher borrowing cost in the current market environment.
• The notes are unsecured, meaning they are effectively subordinated to any secured debt the company or its guarantors may have, which could impact recovery in a default scenario.
• The notes are effectively subordinated to all existing and future indebtedness and liabilities of non-guarantor subsidiaries, potentially limiting the pool of assets available for recovery by noteholders.

Risks

• **Change of Control Repurchase Event**: A significant risk exists if a 'Change of Control' occurs and the notes' rating is subsequently lowered to 'Below Investment Grade' by two or more rating agencies, requiring the company to repurchase the notes at a premium (101% of principal), which could create a substantial liquidity demand.
• **Subordination Risk**: The notes' unsecured nature and effective subordination to secured debt and non-guarantor subsidiary liabilities mean that in a liquidation or bankruptcy, holders of secured debt and creditors of non-guarantor subsidiaries would have priority in claims against their respective assets.
• **Interest Rate Risk**: While fixed-rate notes provide payment predictability, they expose the company to interest rate risk if market rates decline significantly, as the company would be locked into higher interest payments, although optional redemption provisions offer some mitigation.
• **Project Execution Risk**: The use of proceeds for 'eligible green projects' implies reliance on the successful identification, acquisition, investment, and performance of these projects to generate expected returns and support debt service.

Future Outlook

The Company intends to use the net proceeds from the offering to acquire, invest in, or refinance new and/or existing eligible green projects, with disbursements expected within two years following the issue date. Any remaining net proceeds will be invested in interest-bearing accounts and short-term, interest-bearing securities.

Management Comments

• Jeffrey A. Lipson, President and Chief Executive Officer, certified the terms of the new notes and compliance with Indenture conditions.
• Charles W. Melko, Executive Vice President, Chief Financial Officer, and Treasurer, signed the Indenture on behalf of the Company and Guarantors.
• Steven L. Chuslo, Executive Vice President and Chief Legal Officer, signed the Form 8-K.

Industry Context

This debt issuance by HA Sustainable Infrastructure Capital, Inc. (HASI) highlights the growing trend of 'green finance' within the sustainable infrastructure sector. The focus on funding eligible green projects aligns with increasing investor demand for ESG (Environmental, Social, and Governance) compliant investments. The refinancing component suggests a proactive approach to capital structure management in a dynamic interest rate environment, common among infrastructure and real estate investment trusts (REITs) that rely heavily on debt financing.

Stakeholder Impact

• **Shareholders**: Potential for increased long-term value through strategic green investments and optimized capital structure, but also potential for increased interest expense impacting earnings.
• **Creditors (Note Holders)**: New senior unsecured debt holders will receive fixed interest payments and principal repayment, with guarantees from key subsidiaries. Their claims are pari passu with other senior unsecured debt but subordinated to secured debt.
• **Existing Debt Holders**: The proceeds will be used to fund tender offers for existing notes, potentially allowing some holders to exit their positions.
• **Employees**: No direct impact mentioned, but successful project funding could support job stability and growth.
• **Customers/Suppliers**: No direct impact mentioned, but investment in green projects could lead to new business opportunities.

Next Steps

• Acquire, invest in, or refinance new and/or existing eligible green projects.
• Disbursements for green projects to be made within two years following the issue date.
• Invest any remaining net proceeds in interest-bearing accounts and short-term, interest-bearing securities.
• Continue semi-annual interest payments on January 15 and July 15, starting January 15, 2026.
