CarbonCount Holdings 1 LLC to Issue $508 Million of 20-Year Fixed Rate Senior Unsecured Notes

HA Sustainable Infrastructure Capital, Inc. ("HASI") (NYSE:HASI), a leading investor in sustainable infrastructure assets, and KKR, a leading global investment firm, today announced that CarbonCount Holdings 1 LLC ("CCH1"), a co-investment vehicle between HASI and KKR, has issued $508 million in aggregate principal amount of senior unsecured notes (the "Notes") in a private offering. The fixed-rate amortizing notes will have a 20-year final maturity. The Notes were priced at a weighted average coupon of 6.29%. These Notes represent the second issuance of senior notes by CCH1, following its inaugural issuance in June 2025, which priced at a weighted-average coupon of 6.76%.

"We are excited to further expand the investment capacity of CCH1 to support the strong growth in investment activity we are experiencing and continue to enhance our capital efficiency," said HASI Senior Managing Director of Syndications Dan McMahon. "Moreover, five new institutional investors participated in the offering, and spreads improved by more than 30 basis points, compared to the first issuance last year, reflecting how the quality of our underlying assets is translating into a lower cost of capital."

"The strong investor reception of CCH1's second issuance reflects the quality and diversity of the underlying asset base," said Cecilio Velasco, Managing Director, KKR. "With more than $4 billion of investment capacity at CCH1, we are well-positioned to continue collaborating with HASI to deliver sustainable, reliable, and affordable energy infrastructure to meet the significant demand we see across the U.S."

After deducting the estimated offering expenses, the net proceeds from the offering of the Notes are expected to be approximately $503 million. CCH1 intends to utilize the net proceeds to acquire, or invest in, new and/or existing sustainable infrastructure projects, in whole or in part.

Formed in May 2024 as a strategic partnership between HASI and KKR to invest in clean energy projects across the United States, CCH1 was established with an initial capital commitment of up to $2 billion over an 18-month period, and in December 2025, HASI and KKR each agreed to upsize their combined commitment to $3 billion, with each party committing an additional $500 million, and extend the investment period to the earlier of the end of 2027 or when all commitments have been utilized. With this transaction, CCH1's investment capacity has been increased to more than $4 billion, and both parties continue to expect total investment capacity to reach nearly $5 billion based on the existing leverage targets.

Morgan Stanley and HASI Securities served as Joint Lead Placement Agents on the transaction.

The Notes were offered only to persons reasonably believed to be institutional accredited investors as defined in Rule 501(a)(1), (2), (3), (7), or (9) under the Securities Act of 1933 (the "Securities Act") that are also "qualified purchasers" within the meaning of Section (2)(a)(51)(A) of the Investment Company Act of 1940. The Notes have not been, and are not required to be, registered under the Securities Act or any state securities laws and may not be offered or sold in the United States absent an applicable exemption from the registration requirements of the Securities Act or any state securities laws.
