HASI Announces Cash Tender Offer for up to $500 Million Aggregate Principal Amount of 3.375% Senior Notes Due 2026 and 8.00% Green Senior Unsecured Notes Due 2027

ANNAPOLIS, Md.--(BUSINESS WIRE)--HA Sustainable Infrastructure Capital, Inc. (“HASI”) (NYSE: HASI), a leading investor in sustainable infrastructure assets, today announced that its wholly-owned subsidiaries HAT Holdings I LLC, a Maryland limited liability company (“HAT I”) and HAT Holdings II LLC, a Maryland limited liability company (“HAT II,” and together with HAT I, the “Company”) commenced a cash tender offer (the “Tender Offer”) to purchase the outstanding notes listed in the table below (collectively, the “Notes” and each a “Series” of Notes) having an aggregate principal amount of up to $500,000,000 (as it may be increased or decreased by the Company in accordance with applicable law, the “Maximum Aggregate Principal Amount”), in the order of priority, and subject to the Series Cap shown in the table below.

The terms and conditions of the Tender Offer are described in an Offer to Purchase dated June 12, 2025 (as it may be amended or supplemented, the “Offer to Purchase”). The Tender Offer is subject to the satisfaction of certain conditions as set forth in the Offer to Purchase, including the receipt of aggregate gross proceeds in an amount sufficient to effect the repurchase of the Notes validly tendered and accepted for purchase pursuant to the Offer to Purchase on or prior to the Early Settlement Date on terms acceptable to the Company from the concurrent public offering of senior debt securities issued by HASI and guaranteed on a senior basis by the Company and certain other of HASI’s subsidiaries (the “Guarantors”).

Subject to applicable law, the Company may waive any and all of these conditions or extend, terminate or withdraw the Tender Offer with respect to one or more Series of Notes including increase or decrease the Maximum Aggregate Principal Amount and/or increase, decrease or eliminate the Series Cap at any time, including on or after the Price Determination Date. The Tender Offer is not conditioned upon any minimum amount of Notes being tendered. Capitalized terms used in this news release and not defined herein have the meanings given to them in the Offer to Purchase.

The amounts of each Series of Notes that are purchased in the Tender Offer will be determined in accordance with the priorities identified in the column “Acceptance Priority Level” in the table above and will be subject to the Series Cap. The Tender Offer will expire at 5:00 p.m., New York City time, on July 14, 2025, unless extended (such date and time, as the same may be extended, the “Expiration Date”) or earlier terminated. In order to receive the applicable Total Tender Offer Consideration, holders of Notes subject to the Tender Offer must validly tender and not validly withdraw their Notes before the Early Tender Deadline, which is 5:00 p.m., New York City time, on June 26, 2025, unless extended. Holders of Notes subject to the Tender Offer who validly tender their Notes after the Early Tender Deadline and before the Expiration Date and whose Notes are accepted for purchase will receive the applicable Late Tender Offer Consideration.

The applicable Total Tender Offer Consideration for each $1,000 in principal amount of Notes tendered and not withdrawn before the Early Tender Deadline and accepted for payment pursuant to the Tender Offer on the Early Settlement Date (as defined below) will be determined in the manner described in the Offer to Purchase. The consideration will be determined by reference to a fixed spread specified for each Series of Notes over the yield based on the bid-side price of the applicable Reference U.S. Treasury Security specified in the table above, as fully described in the Offer to Purchase. The consideration will be calculated by the Dealer Managers for the Tender Offer at 9:00 a.m., New York City time, on the business day immediately following the Early Tender Deadline, unless extended (such date and time, as the same may be extended, the “Price Determination Date”). The Price Determination Date is expected to be June 27, 2025. The Early Tender Premium for each Series of Notes is $30 per $1,000 principal amount of Notes. The Late Tender Offer Consideration for the Notes purchased pursuant to the Tender Offer will be calculated by taking the Total Tender Offer Consideration for the applicable Series of Notes and subtracting from it the Early Tender Premium of $30 per $1,000 principal amount of Notes.

In addition to the applicable Total Tender Offer Consideration or applicable Late Tender Offer Consideration, as the case may be, accrued and unpaid interest up to, but not including, the applicable Settlement Date will be paid in cash on all validly tendered Notes accepted for purchase in the Tender Offer. The purchase price plus accrued and unpaid interest for Notes that are validly tendered and not validly withdrawn on or before the Early Tender Deadline and accepted for purchase will be paid by the Company in same day funds promptly following the Early Tender Deadline (the “Early Settlement Date”). The Company expects that the Early Settlement Date will be June 30, 2025, the second business day after the Early Tender Deadline. The purchase price plus accrued and unpaid interest for Notes that are validly tendered after the Early Tender Deadline and on or before the Expiration Date and accepted for purchase will be paid by the Company in same day funds promptly following the Expiration Date (the “Final Settlement Date”). The Company expects that the Final Settlement Date will be July 16, 2025, the second business day after the Expiration Date, assuming Notes representing an aggregate principal amount equal to the Maximum Aggregate Principal Amount are not purchased on the Early Settlement Date. No tenders will be valid if submitted after the Expiration Date. If Notes are validly tendered and not validly withdrawn having an aggregate principal amount equal to or greater than the Maximum Aggregate Principal Amount as of the Early Tender Deadline, Holders who validly tender Notes after the Early Tender Deadline but on or before the Expiration Date will not have any of their Notes accepted for purchase, subject to the Series Cap. Holders of Notes subject to the Tender Offer who validly tender their Notes on or before the Early Tender Deadline may not withdraw their Notes after 5:00 p.m., New York City time, on June 26, 2025, unless extended (such date and time, as the same may be extended, the “Withdrawal Deadline”), except in the limited circumstances described in the Offer to Purchase. Holders of Notes subject to the Tender Offer who validly tender their Notes after the Withdrawal Deadline but on or before the Expiration Date may not withdraw their Notes except in the limited circumstances described in the Offer to Purchase.

Subject to the Maximum Aggregate Principal Amount and the Series Cap, all Notes validly tendered and not validly withdrawn at or before the Early Tender Deadline having a higher Acceptance Priority Level will be accepted before any validly tendered and not validly withdrawn Notes having a lower Acceptance Priority Level, and all Notes validly tendered after the Early Tender Deadline having a higher Acceptance Priority Level will be accepted before any Notes tendered after the Early Tender Deadline having a lower Acceptance Priority Level. However, if Notes are validly tendered and not validly withdrawn having an aggregate principal amount less than the Maximum Aggregate Principal Amount as of the Early Tender Deadline, Notes validly tendered and not validly withdrawn at or before the Early Tender Deadline, subject to the Series Cap, will be accepted for purchase in priority to Notes tendered after the Early Tender Deadline, even if such Notes tendered after the Early Tender Deadline have a higher Acceptance Priority Level than Notes validly tendered and not validly withdrawn at or before the Early Tender Deadline. Notes of the Series in the last Acceptance Priority Level accepted for purchase in accordance with the terms and conditions of the Tender Offer may be subject to proration so that the Company will only accept for purchase Notes having an aggregate principal amount of up to the Maximum Aggregate Principal Amount.

From time to time, the Company may purchase additional Notes in the open market, in privately negotiated transactions, through tender offers or otherwise, or may redeem Notes pursuant to the terms of the applicable indenture governing the applicable Series of Notes. Any future purchases or redemptions may be on the same terms or on terms that are more or less favorable to Holders of Notes than the terms of the Tender Offer. Any future purchases by the Company will depend on various factors existing at that time. There can be no assurance as to which, if any, of these alternatives (or combinations thereof) the Company may choose to pursue in the future. The effect of any of these actions may directly or indirectly affect the price of any Notes that remain outstanding after the consummation or termination of the Tender Offer.

Notwithstanding any other provision of the Tender Offer, the Company’s obligation to accept for purchase, and to pay for, Notes validly tendered and not validly withdrawn, if applicable, pursuant to the Tender Offer (up to the Maximum Aggregate Principal Amount, the Series Cap and subject to proration) is subject to, and conditioned upon, the satisfaction of or, where applicable, its waiver of, the General Conditions (as defined below) and the condition that the Company receive aggregate gross proceeds from the Concurrent Notes Offering on or prior to the Early Settlement Date in an amount that is sufficient to effect the repurchase of the Notes validly tendered and accepted for purchase pursuant to this Offer to Purchase, on terms satisfactory to the Company in its sole discretion (the “Financing Condition”).
