Hannon Armstrong Upsizes & Prices Green Bonds Offering of $375 Million of 3.75% Senior Unsecured Notes & $125 Million of 0% C...

Hannon Armstrong Sustainable Infrastructure Capital, Inc. (“Hannon Armstrong” or the “Company”) (NYSE: HASI), a leading investor in climate change solutions, today announced it has upsized and priced its private offering of $375 million in aggregate principal amount of 3.75% senior unsecured notes due 2030 (the “Senior Unsecured Notes”) by its indirect subsidiaries, HAT Holdings I LLC (“HAT I”) and HAT Holdings II LLC (“HAT II,” and together with HAT I, the “Issuers”). The offering was upsized from the previously announced $350 million in aggregate principal amount.

The Senior Unsecured Notes will be guaranteed by the Company, Hannon Armstrong Sustainable Infrastructure, L.P., and Hannon Armstrong Capital, LLC. The settlement of the Senior Unsecured Notes is expected to occur on August 25, 2020, subject to customary closing conditions. The Notes (as defined below) are expected to be rated BB+ by Standard & Poor's Rating Services and Fitch Ratings.

The Company believes the Notes meet the environmental eligibility criteria for green bonds as defined by the International Capital Market Association’s Green Bond Principles. The Company intends to utilize the net proceeds of the offering of the Notes to acquire or refinance, in whole or in part, eligible green projects, which include assets that are neutral to negative on incremental carbon emissions. In addition, these projects may include projects with disbursements made during the twelve months preceding the issue date of the bonds and those with disbursements to be made following the issue date. Prior to the full investment of such net proceeds, the Company intends to invest such net proceeds in interest-bearing accounts and short-term, interest-bearing securities which are consistent with the Company's intention to continue to qualify for taxation as a REIT.

The Senior Unsecured Notes and the related guarantees will be offered only to persons reasonably believed to be qualified institutional buyers in reliance on Rule 144A under the Securities Act of 1933, as amended (the “Securities Act”), and non-U.S. persons outside the United States pursuant to Regulation S under the Securities Act. The Senior Unsecured Notes and the related guarantees will not be registered under the Securities Act or any state securities laws and may not be offered or sold in the United States absent an effective registration statement or an applicable exemption from the registration requirements of the Securities Act or any state securities laws.

Additionally, the Company announced the pricing of its underwritten public offering of $125 million aggregate principal amount of its 0% convertible senior notes due August 2023 (the “Convertible Notes,” and together with Senior Unsecured Notes, the “Notes”). The Company has granted to the underwriters a 30‑day over-allotment option to purchase up to an additional $18.75 million aggregate principal amount of the Convertible Notes.

The Convertible Notes will not bear regular interest, and the principal amount of the Convertible Notes will not accrete. The conversion rate will initially equal 20.6779 shares of common stock per $1,000 principal amount of notes, which is equivalent to a conversion price of approximately $48.36 per share of common stock, representing a 27.5% conversion premium based on the closing price of the Company's common stock of $37.93 per share on August 18, 2020. The initial conversion rate is subject to adjustment upon the occurrence of certain events. The Convertible Notes will mature on August 15, 2023. The offering of the Convertible Notes is expected to close on or about August 21, 2021, subject to customary closing conditions.

Morgan Stanley is acting as a sole book-running manager and Oppenheimer & Co. Inc. is acting as a co-manager for the offering of the Convertible Notes.

A registration statement relating to the Convertible Notes has been filed with the Securities and Exchange Commission ("SEC") and has become effective. The offering of the Convertible Notes will be made by means of a preliminary prospectus supplement and accompanying prospectus. A copy of the preliminary prospectus supplement and accompanying prospectus related to the offering of the Convertible Notes can be obtained by contacting Morgan Stanley & Co. LLC, Attention: Prospectus Department, 180 Varick Street, 2nd Floor, New York, NY 10014, or email: [e-mail].
