1. The Company

Hannon Armstrong Sustainable Infrastructure Capital, Inc. (“HASI” or the “Company”) provides debt and equity financing for sustainable infrastructure projects that increase energy efficiency, provide cleaner energy sources, positively impact the environment or make more efficient use of natural resources.

On April 23, 2013, the Company completed its initial public offering (“IPO”) of 13,333,333 shares of common stock priced at $12.50 per share. The common stock is listed on the New York Stock Exchange under the symbol “HASI”. The net proceeds to the Company from the IPO were approximately $160.1 million, after deducting underwriting discounts and commissions and IPO and formation transaction costs of approximately $4.9 million, which amount includes net proceeds of approximately $9.5 million received by the Company upon the exercise by the underwriters of their option to purchase an additional 818,356 shares of common stock on May 23, 2013.

Concurrently with the IPO, the Company completed a series of transactions, which are referred to as the formation transactions, that resulted in Hannon Armstrong Capital, LLC (the “Predecessor”), the entity that operated the historical business prior to the consummation of the IPO, becoming an indirect subsidiary of HASI.

The significant elements of the formation transactions included:

To the extent any of the financial data included in this quarterly report is as of or from a period prior to April 23, 2013, such financial data is that of the Predecessor. The financial data for the Predecessor for such periods do not reflect the material changes to the business as a result of the capital raised in the IPO, including the broadened types of projects undertaken, the enhanced financial structuring flexibility and the ability to retain a larger share of the economics from the origination activities. Accordingly, the financial data for the Predecessor is not necessarily indicative of the Company’s results of operations, cash flows or financial position following the completion of the IPO and formation transactions.

The Company’s and its subsidiaries’ principal business is providing or arranging financing of sustainable infrastructure projects. The Company and its subsidiaries finance their business through the use of the Company’s own capital and debt, the securitization of receivables and the use of nonrecourse debt. The Company also generates fee income for arranging financings that are held directly on the balance sheet of other investors, by providing broker/dealer or other financing related services to sustainable infrastructure project developers and by servicing the Company’s managed assets. Some of the Company’s subsidiaries are special purpose entities that are formed for specific operations associated with financing sustainable infrastructure receivables for specific long-term contracts.
