NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

(UNAUDITED)

SEPTEMBER 30, 2013

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.

2. Summary of Significant Accounting Policies

Basis of Presentation

The condensed consolidated financial statements reflect all normal and recurring adjustments which, in the opinion of management, are necessary for a fair presentation of the financial position, results of operations, comprehensive income (loss) and cash flows for the periods presented. The preparation of financial statements in accordance with U.S. generally accepted accounting principles (“U.S. GAAP”) requires management to make

- 5 -

Table of Contents

estimates and assumptions that affect the reported amounts of assets and liabilities and the reported amounts of revenues and expenses during the reporting period. The results of operations for the periods presented are not necessarily indicative of the results to be expected for the entire year. Certain information and footnote disclosures normally included in our annual consolidated financial statements have been condensed or omitted.

The condensed consolidated financial statements include the accounts of the Company and its controlled subsidiaries, including the Operating Partnership which was formed to acquire and directly or indirectly own the Company’s assets. All significant intercompany transactions and balances have been eliminated in consolidation.

Financing receivables

Financing receivables include financing sustainable infrastructure project loans, receivables and direct finance leases. The Company accounts for leases as direct finance leases in accordance with the Financial Accounting Standards Board (“FASB”) Accounting Standards Codification (“ASC”) 840, Leases.

A financing receivable represents the present value of the minimum note or lease payments, net of any unearned fee income, which is recognized as income over the term of the note or lease using the interest method.

In September 2013, the Company purchased a financing receivable that was securitized in October 2013. This financing receivable was recorded at cost, which approximated fair value, and was classified as a financing receivable held for sale as of September 30, 2013 on the condensed consolidated balance sheet.

Investments

Investments include debt or equity securities that meet the criteria of ASC 320, Investments—Debt and Equity Securities. The Company intends to hold these securities to maturity and thus records them on the balance sheet using an amortized cost basis.

Securitization of Receivables

During the nine months ended September 30, 2013 and 2012, the Company transferred receivables in multiple securitization transactions. The Company has established various special purpose entities or securitization trusts for the purpose of securitizing certain financing receivables or other debt investments. The Company determined that the trusts used in securitizations are variable interest entities, as defined in ASC 810, Consolidation. The Company typically serves as primary or master servicer of these trusts; however, as the servicer, the Company does not have the power to make significant decisions impacting the performance of the trusts. Based on an analysis of the structure of the trusts, under GAAP, the Company has concluded that it is not the primary beneficiary of the trusts as it does not have power over the trusts’ significant activities. Therefore, the Company does not consolidate these trusts in the condensed consolidated financial statements.

The Company accounts for transfers of financing receivables to these securitization trusts as sales pursuant to ASC 860, Transfers and Servicing, as the transferred receivables have been isolated from the transferor (i.e., put presumptively beyond the reach of the transferor and its creditors, even in bankruptcy or other receivership) and the Company has surrendered control over the transferred receivables. When the Company sells receivables in securitizations, it generally retains interests in the form of servicing rights and residual interest, which are carried on the condensed consolidated balance sheets as retained interests in securitized receivables.

Gain or loss on sale of receivables is calculated based on the excess of the proceeds received from the securitization (less any transaction costs) plus any retained interests obtained over the cost basis of the receivables sold. The Company generally transfers the receivables to securitization trusts immediately upon the initial funding from the third party purchasing a beneficial interest in the trust. For retained interests, the Company generally estimates fair value based on the present value of future expected cash flows using its best estimates of the key assumptions of anticipated losses, prepayment rates, and discount rates commensurate with the risks involved.

As described above, the Company initially accounts for all separately recognized servicing assets and servicing liabilities at fair value as required under ASC 860. Under ASC 860-50, Transfers and Servicing—Servicing Assets and Liabilities, entities may either subsequently measure servicing assets and liabilities using the amortization method or the fair value measurement method and the Company has selected the amortization method to subsequently measure its servicing assets. The Company assesses servicing assets for impairment at each reporting date. If the amortized cost of servicing assets is greater than the estimated fair value, the Company recognizes an impairment in net income.

- 6 -

Table of Contents

The Company’s other retained interest in securitized assets, the residual assets, are classified as available-for-sale securities and carried at fair value on the consolidated balance sheets. The Company generally does not sell its residual interests. If the Company makes an assessment that (i) it does not intend to sell the security or (ii) it is not likely the Company will be required to sell the security before its anticipated recovery, changes in fair value, such as those resulting from changes in market interest yield requirements, are reported as a component of accumulated other comprehensive income. However, in the case where the Company does intend to sell its residual interest or if the fair value of other retained assets is below the current carrying amount and the Company determines that the decline is other than a temporary impairment (“OTTI”), any impairment charge would be recorded through the statement of operations. An OTTI is considered to have occurred when, based on current information and events, there has been an adverse change in the timing or amount of cash flows expected to be collected. The impairment is equal to the difference between the residual asset’s amortized cost basis and its fair value at the balance sheet date. In the case where there is any expected decline in the forecasted cash flows, such decline would be unlikely to reverse during the holding period of the retained interests and thus would be considered OTTI.

Servicing income is recognized as received. Servicing assets are amortized in proportion to, and over the period of, estimated net servicing income, and are periodically (including at September 30, 2013 and 2012) assessed for impairment.

Interest income related to the residual assets is recognized using the effective interest rate method. If there is a change in expected cash flows related to the residual assets, the Company calculates a new yield based on the current amortized cost of the residual assets and the revised expected cash flows. This yield is used prospectively to recognize interest income.

Cash and Cash Equivalents

Cash and cash equivalents at September 30, 2013 and December 31, 2012 include short-term government securities, certificates of deposit and money market funds, all of which had an original maturity of three months or less at the date of purchase. These securities are carried at their purchase price.

Income Taxes

The Company intends to elect and qualify to be taxed as a real estate investment trust (“REIT”) under Section 856 through 860 of the Internal Revenue Code, commencing with its taxable year ending December 31, 2013. To qualify as a REIT, the Company must meet a number of organizational and operational requirements, including a requirement that it currently distribute at least 90% of its net taxable income, excluding capital gains, to its shareholders. The Company intends to meet the requirements for qualification as a REIT and to maintain such qualification. As a REIT, the Company is not subject to federal corporate income tax on that portion of net income that is currently distributed to its owners. However, the Company’s taxable REIT subsidiaries (“TRS”) will generally be subject to federal, state, and local income taxes. No provision for federal or state income tax was recorded for the three and nine-month period ended September 30, 2013 as the REIT intends to distribute 100% of its taxable income and the TRS had insignificant pre-tax income.

The Company accounts for income taxes using the asset and liability method. Deferred tax assets and liabilities are recognized for the estimated future tax consequences attributable to the differences between the consolidated financial statement carrying amounts of existing assets and liabilities and their respective tax bases. Deferred tax assets and liabilities are measured using enacted tax rates in effect for the year in which those temporary differences are expected to be recovered or settled. The effect on deferred tax assets and liabilities from a change in tax rates is recognized in earnings in the period when the new rate is enacted. The Company established deferred tax liabilities related to book and tax differences of certain assets contributed to the TRS in connection with the formation transactions.

Prior to the completion of the IPO, the Predecessor was taxed as a partnership for U.S. federal income tax purposes. No provision for federal or state income taxes has been made in the accompanying condensed consolidated financial statements, since the Company’s profits and losses are reported on the Predecessor’s members’ tax returns. The Company has no uncertain tax positions as of September 30, 2013 and December 31, 2012.

Equity-Based Compensation

From time to time, the Company may award non-vested restricted shares as compensation to members of its senior management team, its independent directors, advisors, consultants and other personnel under an equity incentive plan as further described in Note 10. The shares issued to officers and employees vest over a period of time as determined by the Board of Directors at the date of grant. The Company recognizes compensation expense for non-vested shares that vest solely based on service conditions on a straight-line basis over the vesting period based upon the fair market value of the shares on the date of grant, adjusted for forfeitures.

Earnings Per Share

The Company computes earnings per share of common stock in accordance with ASC 260, Earnings Per Share. Basic earnings per share is calculated by dividing net income attributable to controlling stockholders (after consideration of the earnings allocated to unvested shares of restricted common stock or restricted stock units) by the weighted-average number of shares of common stock outstanding during the period excluding the weighted average number of unvested shares of restricted common stock or restricted stock units (“participating securities” as defined in Note 11). Diluted earnings per share is calculated by dividing net income attributable to controlling stockholders by the weighted-average number of shares of common stock outstanding during the period plus other potentially dilutive securities. No adjustment is made for shares that are anti-dilutive during a period.

Due to the capital structure of the Predecessor, earnings per share of common stock information has not been presented for historical periods prior to the IPO.

Segment Reporting

The Company provides and arranges debt and equity financing for sustainable infrastructure projects and reports all of its activity as one business segment.

Recent Accounting Pronouncement

Accounting Standards Update No. 2013-02—“Comprehensive Income (Topic 220): Reporting of Amounts Reclassified Out of Accumulated Other Comprehensive Income” (“ASU No. 2013-02”), which was adopted in the first quarter of 2013, amends existing guidance by requiring disclosure of changes in the components of accumulated other comprehensive income for the current period and additional information about items reclassified out of accumulated other comprehensive income. The adoption of ASU No. 2013-02 did not have a material effect on the current interim condensed consolidated financial statements.

3. Fair Value Measurements

The levels of inputs used to determine fair value of the Company’s financial assets and liabilities investments are characterized in accordance with the fair value hierarchy established by ASC 820, Fair Value Measurements. Where inputs for a financial asset or liability fall in more than one level in the fair value hierarchy, the financial asset or liability is classified in its entirety based on the lowest level input that is significant to the fair value measurement of that financial asset or liability. The Company uses its judgment and considers factors specific to the financial assets and liabilities in determining the significance of an input to the fair value measurements. At September 30, 2013 and December 31, 2012, only the Company’s residual interests in securitized receivables and derivatives are carried at fair value on the condensed consolidated balance sheets on a recurring basis. The three levels of the fair value hierarchy are described below:

- 8 -

Table of Contents

As of September 30, 2013 and December 31, 2012, the aggregate fair value of financing receivables (including the financing receivable held for sale) was $359.4 million and $207.7 million, with a book value of $348.6 million and $191.4 million, respectively. As of September 30, 2013 and December 31, 2012, the aggregate fair value of Investments was $88.5 million and $0, with a book value of $87.5 million and $0, respectively. The fair values of financing receivables and investments are measured using a discounted cash flow model and Level 3 unobservable inputs. The significant unobservable inputs used in the fair value determination of the Company’s financing receivables and investments are discount rates and interest rates in recent comparable transactions. Significant increases in discount rates and recent comparable transactions would result in a significantly lower fair value. Significant decreases in discount rates and recent comparable transactions in isolation would result in a significantly higher fair value.

At September 30, 2013 and December 31, 2012, the Company had residual assets in the condensed consolidated balance sheets relating to its retained interests in securitized receivables. Due to the lack of actively traded market data, the valuation of these residual assets was based on Level 3 unobservable inputs. The significant unobservable inputs used in the fair value measurement of the Company’s residual assets are published U.S government interest rates, estimated securitization cash flows, potential default rates and comparable transactions in related assets of public companies. The discount rates considered, based on observations of market participants on other government-issued securitization transactions, range from 7% to 15%. Based on the high credit quality of the obligors under our underlying assets and our estimates of potential default and prepayment rates, we have used discount rates of 8% to 10% to determine the fair market value of our underlying assets. Significant increases in U.S. Treasury rates or default and prepayment rates would, in isolation, result in a significantly lower fair value measurement. See Note 5 regarding servicing assets and the residual asset sensitivity analysis.

The following table reconciles the beginning and ending balances for residual assets (amounts in thousands):

At September 30, 2013 and December 31, 2012, the aggregate fair value of nonrecourse debt was $199.4 million and $212.7 million, with a carrying value of $187.8 million and $196.0 million, respectively. The fair values of nonrecourse debt are determined using a discounted cash flow model and Level 3 inputs. The significant unobservable inputs used in the fair value determination of the Company’s nonrecourse debt are discount rates and interest rates in recent comparable transactions. Significant increases in discount rates would result in a significantly lower fair value. Significant decreases in discount rates and recent comparable transactions in isolation would result in a significantly higher fair value.

At September 30, 2013 and December 31, 2012, the aggregate fair value and carrying value of the Company’s credit facility was $83.8 million and $4.2 million, respectively. The fair values of the credit facility are determined using a discounted cash flow model and Level 3 inputs. The significant unobservable inputs used in the fair value determination of the Company’s credit facility are discount rates. Significant increases in discount rates would result in a significantly lower fair value. Significant decreases in discount rates in isolation would result in a significantly higher fair value.

The Company’s financial instruments include cash equivalents that are carried at amounts that approximate fair value.

Concentration of Credit Risk

Financial instruments that potentially subject the Company to concentrations of credit risk are principally cash and cash equivalents. At September 30, 2013 and December 31, 2012, the Company had cash deposits held in U.S. banks of $63.1 million and $8.1 million, respectively. Included in these balances are $61.7 million and $6.6 million in bank deposits, respectively, in excess of amounts federally insured.

- 9 -

Table of Contents

Financing receivables, direct financing leases and investments consist of primarily U.S. government-backed receivables, investment grade state and local government receivables and receivables from various sustainable infrastructure projects and do not, in the Company’s view, represent a significant concentration of credit risk.

4. Non-Controlling Interest

Non-Controlling Interest in Consolidated Entities

The Company consolidates its Operating Partnership. Interests in the Operating Partnership, represented by OP units, that are owned by other limited partners are included in non-controlling interest on the Company’s condensed consolidated balance sheets. As of September 30, 2013, the Operating Partnership had 16,992,256 OP units outstanding, of which 97.3% were owned by the Company and 2.7% were owned by other limited partners. The outstanding OP units held by outside limited partners are redeemable for cash, or at the option of the Company, for a like number of shares of common stock of the Company.

The following is an analysis of the controlling and non-controlling interest from April 23, 2013, the date of` the IPO, to September 30, 2013 (amounts in thousands):

Allocation of Profit and Loss and Cash Distributions prior to April 23, 2013

The member interests of the Predecessor were represented by Series A Participating Preferred Units (“Preferred Units”) and Class A Common Units (“Common Units”). On October 10, 2012, the Company made a return of capital to the Preferred Units holders and paid all outstanding accrued distributions which reduced the Preferred Units’ capital and unpaid annual yield to zero. Prior to the IPO, the Preferred Units remained outstanding without a mandatory dividend and were pari passu with the Common Units for future distributions. For the period prior to April 23, 2013 and as of December 31, 2012, all profits, losses and cash distributions were allocated based on the percentages as follows:

- 10 -

Table of Contents

Upon the completion of the IPO, the Preferred Units and Common Units were exchanged for shares of the Company’s common stock or OP units in the operating partnership, or for certain unit holders, were redeemed for cash.

5. Securitization of Receivables

The Company sold financing receivables in securitization transactions, recognizing gains of $1.9 million and $2.8 million for the three and nine months ended September 30, 2013, respectively, as compared to $0.3 million and $2.0 million for the three and nine months ended September 30, 2012, respectively. In connection with securitization transactions, the Company retained servicing responsibilities and residual interests. In certain instances, the Company receives annual servicing fees ranging from 0.05% to 0.20% of the outstanding balance. The investors and the securitization trusts have no recourse to the Company’s other assets for failure of debtors to pay when due. The Company’s residual interests are subordinate to investors’ interests, and their values are subject to credit, prepayment and interest rate risks on the transferred financial assets.

As of September 30, 2013 and December 31, 2012, the fair values of retained interests, discount rates used in valuing those interests and the sensitivity to an increase in the discount rates of 5% and 10% were as follows (amounts in thousands):

In computing gains and losses on securitizations recorded during the three and nine months ended September 30, 2013 and 2012, the discount rates were consistent with the discount rates presented in the above table. Based on the nature of the receivables and experience-to-date, the Company does not currently expect to incur any credit losses on the receivables sold.

The following is an analysis of certain cash flows between the Company and the securitization trusts for the nine months ended September 30, 2013 and 2012 (amounts in thousands):

- 11 -

Table of Contents

As of September 30, 2013 and December 31, 2012, the Company’s managed receivables totaled $1.9 billion and $1.6 billion, of which $1.5 billion and $1.4 billion were securitized, respectively. There were no credit losses during the three and nine months ended September 30, 2013 and 2012, and no material delinquencies as of September 30, 2013 and December 31, 2012.

6. Financing receivables and Investments

Financing receivables

The components of financing receivables as of September 30, 2013 and December 31, 2012, were as follows (amounts in thousands):

The financing receivables and investments are typically collateralized contractually committed obligations of government entities or private high credit quality obligors and are often supported by additional forms of credit enhancement, including security interests and supplier guaranties. There were no credit losses during the three and nine months ended September 30, 2013 and 2012, and no financing receivables were past due, on nonaccrual status, or impaired as of September 30, 2013 and December 31, 2012. There was no allowance for credit losses as of September 30, 2013 and December 31, 2012.

In accordance with the terms of certain of the financing receivables purchase agreements, the Company pays the purchase price over time, generally within twelve months of entering into the transaction, and as a result, the Company has recorded deferred funding obligations of $77.2 million as of September 30, 2013. The Company has $38.9 million in restricted cash as of September 30, 2013 that will be used to pay certain of these funding obligations.

In May 2013, the Company provided a $24 million loan to a wholly owned subsidiary of EnergySource LLC (“EnergySource”) to be used for a geothermal project. The loan, which matures in May 2018, has an interest rate of 15.22% (of which 6.5% is paid currently and the remainder is accrued against the loan balance). The outstanding balance was $24.8 million as of September 30, 2013 and the interest paid on the loan for the three and nine months ended September 30, 2013 was $0.4 million and $0.6 million, respectively. Certain of the Company’s executive officers and directors have an indirect minority equity interest in EnergySource following the distribution of the Company’s ownership interest as described in note 12 and the loan was approved by the Company’s independent directors.

In September 2013, it was determined that additional time and equity capital would be required to complete the project’s development and EnergySource is presently developing a revised budget, which the Company has the right to approve. EnergySource has been funding the additional costs and approximately $14 million of the loan proceeds have not been spent.

Investments

Investments consist of debt securities that are classified as held-to-maturity and thus recorded at their amortized cost as of September 30, 2013. Included in investments as of September 30, 2013 is a debt security with a carrying value of $37.0 million that matures in 2035 whose obligor is an entity whose ultimate parent is Berkshire Hathaway Inc. and a debt security with a carrying of $35.0 million that matures in 2033 whose obligor is an entity whose ultimate parent is Exelon Corporation. In both cases, the debt securities have an investment grade rating and the carrying value approximates the estimated fair value. There were no investments as of December 31, 2012.

Financing Receivable Held for Sale

In September 2013, the Company purchased a financing receivable that was securitized in October 2013. The carrying value and the fair value of this financing receivable held for sale was $21.1 million as of September 30, 2013. The financing receivable is an amortizing government receivable with a final maturity in February 2038. There were no financing receivables held for sale as of December 31, 2012.

7. Credit Facilities

The Company had outstanding borrowings under its credit facilities of $83.8 million and $4.2 million as of September 30, 2013 and December 31, 2012, respectively. The Company has pledged $81.6 million of financing receivables and $37.5 million of investments as collateral for the credit facility as of September 30, 2013.

In July 2013, the Company entered into a $350.0 million senior secured revolving credit facility through newly-created, wholly-owned special purpose subsidiaries (the “Borrowers”). The terms of the credit facility are set forth in the Loan Agreement (G&I) (the “G&I Loan Agreement”) and the Loan Agreement (PF) (the “PF Loan Agreement”, and together with the G&I Loan Agreement, the “Loan Agreements”) and provide for senior secured revolving credit facilities with total maximum advances of $700.0 million (i) in the case of the G&I Loan Agreement, in the principal amount of $200 million to be used to leverage certain qualifying government and institutional financings entered into by the Company, with maximum total advances (without giving effect to prepayments or repayments) of $400 million, and (ii) in the case of the PF Loan Agreement, in the principal amount of $150 million to be used to leverage certain qualifying project financings entered into by the Company, with maximum total advances (without giving effect to prepayments or repayments) of $300 million. The Company, together with certain of its subsidiaries, have guaranteed the obligations of the Borrowers under each of the Loan Agreements pursuant to (x) a Continuing Guaranty dated July 19, 2013, and (y) a Limited Guaranty dated July 19, 2013. The scheduled termination date of the Loan Agreements is July 19, 2018. Loans under the G&I Loan Agreement bear interest at a rate equal to LIBOR plus 1.50% or, under certain circumstances, the Federal Funds Rate plus 1.50%. Loans under the PF Loan Agreement bear interest at a rate equal to LIBOR plus 2.50% or, under certain circumstances, the Federal Funds Rate plus 2.50%.

Any financing of the Company proposed to be included in the borrowing base as collateral under the Loan Agreements will be subject to the approval of the administrative agent in its sole discretion. The amount eligible to be drawn under the Loan Agreements for purposes of financing such investments will be based on a discount to the value of each investment or an applicable valuation percentage. Under the G&I Loan Agreement, the applicable valuation percentage for non-delinquent investments is 80% in the case of a U.S. Federal Government obligor, 75% in the case of an institutional obligor or a state and local obligor, and with respect to other obligors or in certain circumstances, such other percentage as the administrative agent may prescribe. Under the PF Loan Agreement, the applicable valuation percentage is 67% or such other percentage as the administrative agent may prescribe. The sum of approved financings after taking into account the valuation percentages and any changes in the valuation of the financings determines the borrowing capacity, subject to the overall facility limits described above.

The Company incurred approximately $8.4 million of costs associated with the Loan Agreements that have been capitalized (included in other assets on the condensed consolidated balance sheets) and will be amortized over a 60 month period from July 2013. On each monthly payment date, the Borrowers shall also pay to the administrative agent, for the benefit of the lenders, certain availability fees for each Loan Agreement equal to 0.50%, divided by 360, multiplied by the excess of the available borrowing capacity under each Loan Agreement over the actual amount borrowed under such Loan Agreement.

Each Loan Agreement contains terms, conditions, covenants, and representations and warranties that are customary and typical for a transaction of this nature. The Loan Agreements contain various affirmative and negative covenants, and limitations on the incurrence of liens and indebtedness, investments, fundamental organizational changes, dispositions, changes in the nature of business, transactions with affiliates, use of proceeds and stock repurchases.

Each Loan Agreement also includes customary events of default, including for the existence of a default in more than 50% of underlying financings. The occurrence of an event of default may result in termination of the Loan Agreements, acceleration of amounts due under both Loan Agreements, and accrual of default interest at a rate of LIBOR plus 2.50% in the case of the G&I Loan Agreement and at a rate of LIBOR plus 5.00% in the case of the PF Loan Agreement.

The Loan Agreements require the Company to maintain the following covenants:

As the 12-month rolling Net Interest Margin does not take effect until June 30, 2014, the covenant was not applicable to the Company. For purposes of the Maximum Debt to Equity ratio, debt is defined as total indebtedness excluding accounts payable and accrued expenses and nonrecourse debt.

The Company repaid its Predecessor’s credit facility and a related interest rate swap and cap in April 2013 from the proceeds of the IPO. The interest rate swap was not designated as a hedging instrument under ASC 815, Derivatives and Hedging. The swap was recorded in accounts payable and accrued expenses in the condensed consolidated balance sheet as of December 31, 2012. For the nine months ended September 30, 2013, the Company recorded a $15,000 gain from derivative instruments. For the three and nine months ended September 30, 2012, the Company recorded gains on derivative instruments of $14,000 and $44,000, respectively.

8. Nonrecourse Debt

Certain of the Company’s financing receivables have been financed using nonrecourse debt. When nonrecourse debt is used, the financings are typically collateralized by a security interest in the financing receivables or leased equipment and at no time is the Company liable for nonpayment by the obligor of the financing receivable. An analysis of nonrecourse debt by interest rate as of September 30, 2013 and December 31, 2012 is as follows (amounts in thousands):

Amounts due under nonrecourse notes are secured by financing receivables with a carrying value of $184.2 million as of September 30, 2013 and there is no recourse to the general assets of the Company. Debt service, in a majority of cases, is equal to or less than the lease or financing receivables from the equipment user. Approximately $18.5 million of nonrecourse debt was repaid in April 2013 from the proceeds of the IPO.

10. Stockholder’s Equity

Dividends

Our Board of Directors declared the following dividends in 2013:

See note 12 for distributions in 2012.

Equity Incentive Plan

The Company may issue equity-based awards to members of its senior management team, its independent directors, advisers, consultants and other personnel under the 2013 Equity Incentive Plan (the “2013 Plan”). The 2013 Plan provides for grants of stock options, shares of restricted common stock, phantom shares, dividend equivalent rights, long term incentive plan (“LTIP”) units and other restricted limited partnership units issued by the Operating Partnership and other equity-based awards up to an aggregate of 7.5% of the shares of common stock issued and outstanding from time to time on a fully diluted basis (assuming, if applicable, the exercise of all outstanding options and the conversion of all warrants and convertible securities, including OP units and LTIP units, into shares of common stock).

Reallocation of the Predecessor’s Membership Units

Concurrently with the IPO, the existing owners of the Predecessor reallocated and distributed a portion of their equity ownership to the employees of the Predecessor. Under this reallocation, employees received 202,826 shares of common stock, 128,348 restricted stock units and 135,938 OP units. This reallocation is accounted for as equity-based compensation in accordance with ASC Topic 718, Compensation — Stock Compensation, with equity award valuations based on the IPO price of $12.50 per share. As the shares of common stock, restricted stock units and OP units were immediately vested, the Company recorded a compensation expense of $5.8 million on April 23, 2013. No tax benefits have been recorded related to this reallocation.

Awards of Shares of Restricted Common Stock

From time to time, the Company may award non-vested shares of restricted common stock under the 2013 Plan as compensation to members of its senior management team, its independent directors, advisers, consultants and other personnel. The Board of Directors determines the vesting period for such shares at the date of grant. For shares issued, the Company recognizes compensation expense for non-vested shares of restricted common stock on a straight-line basis over the vesting period based upon the fair market value of the shares on the date of issuance, adjusted for forfeitures. The calculation of the compensation expense assumes a forfeiture rate up to 5%.

On April 23, 2013, the Company granted 606,415 shares of restricted common stock at a grant-date fair value of $12.50 per share, which vest each anniversary in equal annual installments over a four-year period. For the three months ended September 30, 2013 and for the period from April 23, 2013 through September 30, 2013, the Company recorded $0.4 million and $6.6 million of equity-based compensation expense, respectively, including the compensation expense associated with the reallocation of the Predecessor’s membership units described above. The total unrecognized compensation expense related to awards of shares of restricted common stock subject to a vesting schedule, considering estimated forfeitures, is $6.4 million as of September 30, 2013, which is expected to be recognized over a weighted-average term of approximately two years. The total fair value of shares vested (calculated as number of shares multiplied by vesting date share price) during the nine months ended September 30, 2013 was zero. There were no forfeitures for the three and nine months ended September 30, 2013.

A summary of the non-vested shares of restricted common stock as of September 30, 2013 is as follows:

11. Earnings per Share of Common Stock

Net income or loss figures are presented net of income or loss attributable to the non-controlling Operating Partnership interests in the earnings per share calculations. The limited partners’ outstanding OP units (which may be redeemed for shares of common stock) have also been excluded from the diluted earnings per share calculation attributable to common stockholders as there would be no effect on the amounts since the limited partners’ share of income would also be added back to net income. The weighted average number of OP units held by the non-controlling interest was 462,375 and 461,180 for the three and nine months ended September 30, 2013, respectively.

Unvested share-based payment awards that contain non-forfeitable rights to dividends or dividend equivalents (whether paid or unpaid) are participating securities and shall be included in the computation of earnings per share pursuant to the two-class method. Any shares of common stock which, if included in the diluted earnings per share calculation, would have an anti-dilutive effect, have been excluded from the diluted earnings per share calculation.

For the nine months ended September 30, 2013, distributed and undistributed earnings attributable to unvested shares of restricted common stock and restricted stock units (both of which are participating securities) have been excluded, as applicable, from net income or loss attributable to common stockholders utilized in the basic and diluted earnings per share calculations because the effect of these items on diluted earnings per share would be anti-dilutive. At September 30, 2013, there were 734,763 shares of unvested restricted common stock and restricted stock units. For the nine months ended September 30, 2013, no undistributed earnings were allocated to the unvested restricted common stock or the unvested restricted stock units because the impact on earnings per share attributable to common stockholders would be anti-dilutive.

The computation of basic and diluted earnings per share of common stock is as follows (in thousands, except share and per share data):

12. Equity Method Investment in Affiliate

In December 2012, the Predecessor’s Board of Directors approved the distribution of its entire equity interest in HA EnergySource Holdings LLC (“HA EnergySource”) that owned a minority interest in EnergySource to the Predecessor’s shareholders effective December 31, 2012. Prior to and as part of the transaction, the Board approved a $3.4 million capital commitment to HA EnergySource to be used by HA EnergySource for general corporate purposes, future investments or dividends to HA EnergySource owners. Such amount was included in accounts payable and accrued expenses at December 31, 2012 and was fully paid at September 30, 2013. Prior to December 2012, the Predecessor accounted for its investment using the equity method of accounting. After December 31, 2012, the Company no longer has any direct or indirect ownership in HA EnergySource or EnergySource.

The following is a summary of the financial position of EnergySource as of December 31, 2012, accounted for using the equity method:

The Company has provided investment banking and management services to EnergySource. For the three and nine months ended September 30, 2013, the Company recorded income of $0.03 million and $0.5 million, respectively, as compared to $8.4 million and $8.8 million, for the three and nine months ended September 30, 2012, respectively.

Our Business

We provide 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. We began our business more than 30 years ago, and since 2000, using our direct origination platform, we have provided or arranged over $4.3 billion of financing in more than 450 sustainable infrastructure transactions. Over this period, we have become the leading provider of financing for energy efficiency projects for the U.S. federal government, the largest property owner and energy user in the United States.

- 19 -

Table of Contents

We provide and arrange debt and equity financing primarily for three types of projects, which we refer to together as sustainable infrastructure projects:

We are highly selective in the projects we target. Our goal is to select projects that generate recurring and predictable cash flows or cost savings that will be more than adequate to repay the debt financing we provide or will deliver attractive returns on our equity investments. Our projects are typically characterized by revenues from contractually committed obligations of government entities or private high credit quality obligors and are often supported by additional forms of credit enhancement, including security interests and supplier guaranties. Our projects also generally employ proven technologies which minimize performance uncertainty, enabling us to more accurately predict project revenue and profitability over the term of the financing or investment. As a result of our highly selective approach to project targeting, the credit performance of our originated assets has been excellent. Since 2000, there has been only one incident of realized loss, amounting to approximately $7.0 million (net of recoveries) on the more than $4.3 billion of transactions we originated during that time. This transaction, in an asset class in which we no longer participate, represents an aggregate loss of less than 0.2% on cumulative transactions originated over this time period.

On April 23, 2013, we completed our 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 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. Our strategy in undertaking the IPO was to expand our proven ability to serve the rapidly growing sustainable infrastructure market by increasing our capital resources, enhancing our financial structuring flexibility, expanding the types of projects and end-customers we pursue, and selectively retaining a larger portion of the economics in the financings we originate, while delivering attractive risk-adjusted returns to our stockholders.

As part of our strategy in undertaking the IPO, we expect to hold a significantly larger portion of the loans or other assets we originate on our balance sheet and we intend to finance these loans and other assets using our own capital as well as on balance sheet financings. Thus, we expect over time to see significant increases in both income from financing receivables and investment interest expense. We also expect that our net investment revenue, which represents the margin, or the difference between income from investment interest income and investment interest expense, will increase due to a higher average margin on a per asset basis as well as growth in the overall amount of our investments. We expect our average margin will increase as a result of increased use of equity in place of debt as well as lower anticipated interest rates on our borrowings. We expect to pay lower interest rates due to an expected reduction in our per transaction leverage percentage, which historically was in excess of 95% on a typical transaction, increased access to new capital sources and shortening the term of our borrowings. We expect to see, in comparison to historical periods, a much larger portion of our total revenue derived from net investment revenue and other recurring and predictable revenue sources.

Prior to the IPO, we financed our business primarily through the use of securitizations, including the Hannon Armstrong Multi-Asset Infrastructure Trust, or Hannie Mae. In these transactions, we transfer the loans or other assets we originate to securitization trusts or other bankruptcy remote special purpose funding vehicles. Large institutional investors, primarily insurance companies and commercial banks, historically provided the financing

Table of Contents

needed for a project by purchasing the notes issued by the trust or vehicle. The securitization market for the assets we finance has remained active throughout the financial crisis due to investor demand for high credit quality, long-term investments. Historically, we have arranged such securitizations of loans or other assets prior to originating the transaction and thus have avoided exposure to credit spread and interest rate risks that are normally associated with traditional capital markets conduit transactions. Additionally, we have typically avoided funding risks for these loans or other assets given that our securitization partners contractually agree to fund such assets before the origination transaction is completed.

In most cases, the transfer of loans or other assets to non-consolidated securitization trusts qualify as sales for accounting purposes. In these transactions, we receive economics in the form of gain on sale income, which arises from the difference between the financing rate quoted to our customers and the interest rate required by the investors in our securitizations. This income is reflected in our statement of operations as gain on securitization of receivables. We also typically manage and service these assets in exchange for fees and other payments, which we record as fee income on our statement of operations. We expect to continue to use our traditional securitizations in the future and believe the IPO will also create new opportunities for securitizations.

In some cases, our transactions are accounted for as financings and the assets together with the corresponding nonrecourse debt are carried on our balance sheet. In these transactions, we generate investment interest income and incur investment interest expense. We may periodically provide services, including arranging financings that are held on the balance sheet of other investors and advising various companies with respect to structuring investments.

As of September 30, 2013, of the approximately $1.9 billion of the outstanding financings we own or manage (which we collectively refer to as our managed assets), approximately $1.5 billion was not carried on our balance sheet and was held in non-consolidated securitization trusts and approximately $0.4 billion were held on our balance sheet. Approximately 54% of this portfolio was financings for energy efficiency projects, approximately 36% was financings for clean energy projects such as solar, wind, biomass or other renewable resources as well as combined heat and power, while the remaining 10% of this portfolio was financings for other sustainable infrastructure projects such as water or communication projects. Our managed assets have an average remaining balance of approximately $8.5 million, a weighted average remaining life of approximately 13.3 years and are typically secured by the installed improvements that are the subject of the financing. As of September 30, 2013, 99.5% of our managed portfolio consisted of fixed rate loans, direct financing leases or debt securities with approximately 90% of the portfolio consisting of U.S. federal government obligations.

From April 23, 2013, the date of our IPO, through September 30, 2013, we completed approximately $422 million of transactions, of which $233 million are held on our balance sheet, $149 million were securitized, $19 million represented the repayment of existing notes and $21 million were held for sale. Approximately 34% of these transactions financed energy efficiency projects; approximately 59% financed clean energy projects such as solar, wind, biomass or other renewable resources as well as combined heat and power, while the remaining 7% financed other sustainable infrastructure projects such as water and communication projects. The transactions for which we are receiving economic value on our balance sheet have an average transaction size of approximately $21 million, a weighted average life of approximately 10.6 years and are typically secured by the installed improvements that are the subject of the financing. As of September 30, 2013, our pipeline of new financing opportunities was more than $2.0 billion.

We have a large and active pipeline of potential new financing opportunities that are in various stages of our investment process. We refer to projects as being part of our pipeline if we have determined that the projects fit within our investment strategy and exhibit the appropriate risk/reward characteristics through an initial credit analysis, including a quantitative and qualitative assessment of the investments, as well as research on the market and sponsor. Our pipeline consists of projects where we will either be the lead financier or projects in which we participate that are originated by other institutional investors or intermediaries. As of September 30, our pipeline consisted of more than $2.0 billion in new financing opportunities. There can, however, be no assurance that transactions in our pipeline will be completed.

Factors Impacting our Operating Results

We expect that our results of operations will be affected by a number of factors and will primarily depend on the size of our portfolio, including the portion of our portfolio which we hold on our balance sheet, the income we receive from securitizations, syndications and other services, our portfolio’s credit risk profile, changes in market interest rates, commodity prices, U.S. federal, state and/or municipal governmental policies, general market conditions in local, regional and national economies and our ability to qualify as a REIT and maintain our exception from the 1940 Act.

Critical Accounting Policies and Use of Estimates

Our financial statements are prepared in accordance with U.S. GAAP, which requires the use of estimates and assumptions that involve the exercise of judgment and use of assumptions as to future uncertainties. The following discussion addresses the accounting policies that we use. Our most critical accounting policies will involve decisions and assessments that could affect our reported assets and liabilities, as well as our reported revenues and expenses. We believe that all of the decisions and assessments upon which our financial statements are based are reasonable at the time made and based upon information available to us at that time. Our critical accounting policies and accounting estimates will be expanded over time as we fully implement our strategy. Those material accounting policies and estimates that we expect to be most critical to an investor’s understanding of our financial results and condition and require complex management judgment are discussed below.

Financing receivables

Financing receivables include financing sustainable infrastructure project loans, receivables and direct finance leases. The Company accounts for leases as direct finance leases in accordance with the Financial Accounting Standards Board (“FASB”) Accounting Standards Codification (“ASC”) 840, Leases.

A financing receivable represents the present value of the minimum note or lease payments, net of any unearned fee income, which is recognized as income over the term of the note or lease using the interest method.

Investments

Investments include debt or equity securities that meet the criteria of ASC 320, Investments—Debt and Equity Securities. The Company intends to hold these securities to maturity and thus records them on the balance sheet using an amortized cost basis.

Securitization Transactions

We have established, and may establish in the future, various special purpose entities or securitization trusts for the purpose of securitizing certain financing receivables or other debt investments. We have determined that the trusts used in our securitizations are variable interest entities as defined in ASC, 810, Consolidation. We typically serve as primary or master servicer of these trusts; however, as the servicer, we do not have the power to make significant decisions impacting the performance of the trusts. Based on our analysis of the structure of the trusts, under U.S. GAAP, we are not the primary beneficiary of the trusts as we do not have a controlling financial interest in the trusts because we do not have power over the trusts’ significant activities. Therefore, we do not consolidate these trusts in our consolidated financial statements.

We account for transfers of financing receivables to these securitization trusts as sales pursuant to ASC, 860, Transfers and Servicing, as the transferred receivables have been isolated from the transferor (i.e., put presumptively beyond the reach of the transferor and its creditors, even in bankruptcy or other receivership) and we have surrendered control over the transferred receivables. When we sell receivables in securitizations, we generally retain interests in the form of servicing rights and residual interests which are carried on our consolidated balance sheet as retained interests in securitized receivables.

Gain or loss on sale of receivables is calculated based on the excess of the proceeds received from the securitization (less any transaction costs) plus any retained interests obtained over the cost basis of the receivables sold. We generally transfer the receivables to securitization trusts immediately upon the initial funding from the third party purchasing a beneficial interest in the trust. For our retained interests, we generally estimate fair value based on the present value of future expected cash flows using our best estimates of the key assumptions of anticipated losses, prepayment rates, and discount rates commensurate with the risks involved.

- 22 -

Table of Contents

We initially account, as described above, for all separately recognized servicing assets and servicing liabilities at fair value as required under ASC 860. Under ASC 860-50, Transfers and Servicing—Servicing Assets and Liabilities, entities may either subsequently measure servicing assets and liabilities using the amortization method or the fair value measurement method and we have selected the amortization method to subsequently measure our servicing assets. We assess our servicing assets for impairment at each reporting date. If the amortized cost of our servicing assets is greater than the estimated fair value, we recognize an impairment in net income.

Our other retained interest in securitized assets, the residual assets, are classified as available-for-sale securities and carried at fair value on the consolidated balance sheets. We generally do not sell our retained interests. If we make an assessment that (i) we do not intend to sell the security or (ii) it is not likely we will be required to sell the security before its anticipated recovery, changes in fair value, such as those resulting from changes in market interest yield requirements, are reported as a component of accumulated other comprehensive income. However, in the case where we do intend to sell our retained interest or if the fair value of other retained assets is below the current carrying amount and we determine that the decline is OTTI, any impairment charge would be recorded through the statement of operations. An OTTI is considered to have occurred when, based on current information and events, there has been an adverse change in the timing or amount of cash flows expected to be collected. The impairment is equal to the difference between the residual asset’s amortized cost basis and its fair value at the balance sheet date. In the case where there is any expected decline in the forecasted cash flows, such decline would be unlikely to reverse during the holding period of the retained interests and thus would be considered an OTTI.

Valuation of Financial Instruments

ASC 820 establishes a framework for measuring fair value in accordance with U.S. GAAP and expands financial statement disclosure requirements for fair value measurements. ASC 820 further specifies a hierarchy of valuation techniques, which is based on whether the inputs into the valuation technique are observable or unobservable. Where inputs for a financial asset or liability fall in more than one level in the fair value hierarchy, the financial asset or liability is classified in its entirety based on the lowest level input that is significant to the fair value measurement of that financial asset or liability. At September 30, 2013 and December 31, 2012, we carried only retained interests in securitized receivables and derivatives at fair value on our balance sheets. We use our judgment and consider factors specific to the financial assets and liabilities measured at fair value in determining the significance of an input to the fair value measurements. The hierarchy is as follows:

For financial assets and liabilities carried at fair value, we use quoted market prices, when available, to determine the fair value of an asset or liability. If quoted market prices are not available, we consult independent pricing services or third party broker quotes, provided that there is no ongoing material event that affects the issuer of the securities being valued or the market therefor. If there is such an ongoing event, or if quoted market prices are not available, we will determine the fair value of the securities using valuation techniques that use, when possible, current market-based or independently-sourced market parameters, such as interest rates.

Fair value under U.S. GAAP represents an exit price in the normal course of business, not a forced liquidation price. If we were forced to sell assets in a short period to meet liquidity needs, the prices we receive could be substantially less than their recorded fair values. Furthermore, the analysis of whether it is more likely than not that we will be required to sell securities in an unrealized loss position prior to an expected recovery in value (if any), the amount of such expected required sales, and the projected identification of which securities would be sold is also subject to significant judgment, particularly in times of market illiquidity.

- 23 -

Table of Contents

Any changes to the valuation methodology will be reviewed by our investment committee to ensure the changes are appropriate. As markets and products develop and the pricing for certain products becomes more transparent, we will continue to refine our valuation methodologies. The methods used by us may produce a fair value calculation that may not be indicative of net realizable value or reflective of future fair values. Furthermore, while we anticipate that our valuation methods will be appropriate and consistent with other market participants, the use of different methodologies, or assumptions, to determine the fair value of certain financial instruments could result in a different estimate of fair value at the reporting date. We will use inputs that are current as of the measurement date, which may include periods of market dislocation, during which price transparency may be reduced.

Revenue Recognition

In accordance with our valuation policy, we evaluate accrued income from financing receivables periodically for collectability. When a financing receivable becomes 90 days or more past due, and if we otherwise do not expect the debtor to be able to service all of its debt or other obligations, we will generally place the financing receivable on non-accrual status and cease recognizing income from that financing receivable until the borrower has demonstrated the ability and intent to pay contractual amounts due. If a financing receivable’s status significantly improves regarding the debtor’s ability to service the debt or other obligations, or if a financing receivable is fully impaired, sold or written off, we will remove it from non-accrual status. The revenue recognition for the major components of revenue is accounted for as described below (see “—Critical Accounting Policies and Use of Estimates—Securitization Transactions” for discussion of gains and losses recognized from the securitization of receivables):

- 24 -

Table of Contents

Hedging Instruments and Hedging Activities

We account for derivative financial instruments in accordance with ASC 815, Derivatives and Hedging, which requires us to recognize all derivatives as either assets or liabilities on the balance sheet and to measure those instruments at fair value. Additionally, the fair value adjustments will affect either other comprehensive income or net income depending on whether the derivative instrument qualifies as a hedge for accounting purposes (and the type of hedge) and if we elect to apply hedge accounting for that instrument. We use derivatives for hedging purposes rather than speculation. We value derivative financial instruments in accordance with ASC 820. See “—Critical Accounting Policies and Use of Estimates—Valuation of Financial Instruments.” At September 30, 2013 and December 31, 2012, no derivatives were designated in hedge accounting relationships.

In the normal course of our business, subject to maintaining our qualification as a REIT, we may use a variety of derivative financial instruments to manage or hedge interest rate risk on our borrowings. These derivative financial instruments must be effective in reducing our interest rate risk exposure in order to qualify for hedge accounting. When the terms of an underlying transaction are modified, or when the underlying hedged item ceases to exist, all changes in the fair value of the derivative instrument are marked-to-market with changes in value included in net income for each period until the derivative instrument matures or is settled. Any derivative instrument used for risk management that does not meet the effective hedge criteria or for which we do not elect hedge accounting is marked-to-market with the changes in fair value included in net income.

Income Taxes

We intend to elect and qualify to be taxed as a real estate investment trust, or REIT, for U.S. federal income tax purposes under Section 856 through 860 of the Internal Revenue Code commencing with our taxable year ending December 31, 2013. To qualify as a REIT, the Company must meet a number of organizational and operational requirements, including a requirement that it currently distribute at least 90% of its net taxable income, excluding net capital gains, to its shareholders. We intend to meet the requirements for qualification as a REIT and to maintain such qualification. As a REIT, the Company is not subject to federal corporate income tax on that portion of net income that is currently distributed to its stockholders. However, the Company’s taxable REIT subsidiaries (collectively, the “TRS”) will generally be subject to federal, state, and local income taxes. No provision for federal or state income tax was recorded for the three and nine-month period ended September 30, 2013 as the REIT intends to distribute 100% of its taxable income and the TRS had insignificant pre-tax income. Many of the REIT requirements, however, are highly technical and complex. If we were to fail to meet the REIT requirements, we would be subject to U.S. federal, state and local income taxes.

We account for income taxes using the asset and liability method. Deferred tax assets and liabilities are recognized for the estimated future tax consequences attributable to the differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases. Deferred tax assets and liabilities are measured using enacted tax rates in effect for the year in which those temporary differences are expected to be recovered or settled. The effect on deferred tax assets and liabilities from a change in tax rates is recognized in earnings in the period when the new rate is enacted. The Company established deferred tax liabilities related to book and tax differences of certain assets contributed to the TRS in connection with the formation transactions.

Prior to the completion of the IPO, the Predecessor was taxed as a partnership for U.S. federal income tax purposes. No provision for federal or state income taxes has been made in the accompanying condensed consolidated financial statements, since the Company’s profits and losses are reported on the Predecessor’s members’ tax returns. There were no uncertain tax positions as of September 30, 2013 and December 31, 2012.

Equity-Based Compensation

The Company recorded compensation expense for stock awards in accordance with ASC 718, Compensation—Stock Compensation, which requires that all share-based payments to employees be recognized in the consolidated statements of operations based on their grant date fair values with the expense being recognized over the requisite service period.

Upon the completion of the IPO, we adopted an equity incentive plan that provides for grants of stock options, shares of restricted common stock, phantom shares, dividend equivalent rights, and long term incentive plan (“LTIP”) units and other restricted limited partnership units issued by our operating partnership and other equity-based awards. Equity-based compensation will be recognized as an expense in the financial statements over the vesting period and measured at the fair value of the award on the date of grant. The amount of the expense may be subject to adjustment in future periods depending on the specific characteristics of the equity-based award and the application of ASC 718, Compensation—Stock Compensation.

Earnings Per Share

The Company computes earnings per share of common stock in accordance with ASC 260, Earnings Per Share. Basic earnings per share is calculated by dividing net income attributable to controlling shareholders (after consideration of the earnings allocated to unvested restricted stock shares or units) by the weighted-average number of shares of common stock outstanding during the period excluding the weighted average number of unvested restricted stock shares or units (“participating securities”). Diluted earnings per share is calculated by dividing net income attributable to controlling shareholders by the weighted-average number of shares of common stock outstanding during the period plus other potentially dilutive securities. No adjustment is made for shares that are anti-dilutive during a period.

Due to the capital structure of the Predecessor, earnings per share of common stock information has not been presented for historical periods prior to the IPO.

Results of Operations

As part of our strategy, since the IPO and in the future, we will be holding a significantly larger portion of the loans or other assets we originate on our balance sheet and we intend to finance these loans and other assets using our capital as well as on balance sheet financings. Thus, we expect over time to see significant increases in both investment interest income and investment interest expense. We also expect that our net investment revenue, which represents the margin, or the difference between investment interest income and investment interest expense, will increase due to a higher average margin on a per asset basis as well as growth in the overall amount of our investments. We expect our average margin will increase as a result of increased use of equity in place of debt as well as lower anticipated interest rates on our borrowings. We also expect to continue our practice of securitizing certain transactions, in which we transfer the loans or other assets we originate to securitization trusts or other bankruptcy remote special purpose funding vehicles. As of September 30, 2013, the outstanding principal balance of our managed assets financed through the use of securitizations was approximately $1.52 billion and the outstanding principal balance of the financing receivables and investments held on our balance sheet was approximately $436 million including approximately $184 million financed by nonrecourse debt for total managed assets of approximately $1.96 billion.

To the extent any of the financial data presented below is as of a date 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 historically undertaken, the enhanced financial structuring flexibility and the ability to retain a larger share of the economics from the origination activities. Thus 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 transaction and in the future.

Financing receivables and Investments

At September 30, 2013, we held $436.1 million of managed assets on our balance sheet as financing receivables and investments, which consisted of:

The table below presents, for each major category of our interest-earning assets and interest-bearing liabilities, the average outstanding balances, interest income earned or interest expense incurred, and average yield or cost for the three and nine months ended September 30, 2013 and 2012. Our net interest margin represents the difference between the yield on our interest-earning assets and the cost of our interest-bearing liabilities, including the impact of non-interest bearing funding, primarily equity.

The financing receivables and the debt securities described in the above table are typically collateralized with contractually committed obligations of government entities or private high credit quality obligors and are often supported by additional forms of credit enhancement, including security interests and supplier guaranties. There were no credit losses during the nine months ended September 30, 2013 and 2012, and no financing receivables were past due, on nonaccrual status, or impaired at September 30, 2013 and December 31, 2012. There was no allowance for credit losses as of September 30, 2013 and December 31, 2012.

Comparison of the Three Months Ended September 30, 2013 vs. Three Months Ended September 30, 2012

Net Income

Net income decreased by $4.3 million to $1.9 million for the three months ended September 30, 2013, compared to $6.2 million for the same period in 2012. This decrease was primarily the result of a decrease in other investment revenue of $8.3 million as fee income declined by $9.8 million due to the fees generated from sustainable infrastructure projects in 2012 offset by an increase in gain on securitization of receivables of $1.5 million in the same period in 2013. The decline in other investment revenue was offset by $2.1 million of higher net investment revenue and by a decrease in other expenses of $1.9 million in large part due to higher compensation expense in the same period in 2012 as a result of the higher fee income.

Net Investment Revenue

Net investment revenue increased to $2.6 million in the three months ended September 30, 2013 from $0.5 million in the same period in 2012. The monthly average balance of investments increased to $360.6 million in the three months ended September 30, 2013 from $211.6 million in the same period in 2012, while the average interest rate earned on these assets increased to 5.75% in the three months ended September 30, 2013 from 5.54% in the same period in 2012, resulting in a $2.3 million increase in investment interest income to $5.2 million from $2.9 million in the same period in 2012.

As we began to utilize our new credit facility, the monthly average debt balance increased in the three months ended September 30, 2013 to $245.9 million compared to $216.3 million in the same period in 2012. Investment interest expense increased to $2.6 million in the three months ended September 30, 2013, compared to $2.4 million in the same period in 2012 while the average debt interest rate decreased to 4.21% in 2013 from 4.51% in 2012.

As a result of the higher investments offset by slightly higher debt, net investment revenue increased to $2.6 million in the three months ended September 30, 2013 from $0.5 million in the same period in 2012.

Other Investment Revenue

Gain on securitization of receivables increased by $1.5 million to $1.9 million for the three months ended September 30, 2013 compared to $0.4 million in the same period in 2012. The increase was the result of increased transaction volume. Fee income decreased by $9.8 million to $0.3 million for the three months ended September 30, 2013 compared to $10.1 million for the three months ended September 30, 2012 as a result of higher advisory fees in 2012 primarily due to sustainable infrastructure transactions in 2012.

Total Revenue, Net of Investment Interest Expense

Total revenue, net of investment interest expense decreased by $6.2 million to $4.8 million in the three months ended September 30, 2013, compared to $11.0 million in the same period in 2012, primarily as a result of the decrease in fee income partially offset by an increase in net investment revenue and gain on securitization of receivables.

Other Expenses, Net

Other expenses, net decreased by $1.9 million to $2.9 million in the three months ended September 30, 2013, compared to $4.8 million in the same period in 2012, primarily as a result of lower compensation and benefits costs of $2.2 million and lower general and administrative expenses of $1.0 million partially offset by lower income from equity method investment in affiliate of $1.4 million.

Compensation costs declined $2.2 million due to higher performance based compensation expense associated with the higher fee income in 2012. General and administrative expenses also declined by $1.0 million to $0.9 million in the three months ended September 30, 2013 from $1.9 million in the same period in 2012, primarily due to higher professional fees in 2012 related to the sustainable infrastructure transactions. The decrease in income from equity method investment in affiliate of approximately $1.4 million in 2012 to $0 in the three months ended September 30, 2013 is a result of the distribution of the investment in HA EnergySource on December 31, 2012 to the Company’s previous owners.

Comparison of the Nine Months Ended September 30, 2013 vs. Nine Months Ended September 30, 2012

Net (Loss) Income

We recorded a net loss of $5.1 million for the nine months ended September 30, 2013, compared to $3.7 million of income in the same period in 2012. This decrease was primarily the result of a decrease in other investment revenue of $9.0 million due to the fees generated from sustainable infrastructure projects in 2012. An increase in net investment revenue of $2.9 million resulting from the strategy of increasing the investments held on the balance sheet was offset by a $2.6 million increase in other expenses, net. The increase in other expenses, net was largely the result of a one-time compensation charge of $5.8 million relating to the reallocation between the owners and employees of the equity interest of the Predecessor as part of the IPO and formation transactions.

Net Investment Revenue

Net investment revenue increased by $2.9 million to $4.4 million for the nine months ended September 30, 2013, compared to $1.5 million in the same period in 2012. The monthly average balance of investments increased to $265.6 million for the nine months ended September 30, 2013 from $200.9 million in the same period in 2012, while the average interest rate earned on these assets increased slightly to 5.67% for the nine months ended September 30, 2013 from 5.64% in the same period in 2012, resulting in a $2.8 million increase in investment interest income.

As we began to utilize our new credit facility, the monthly average debt balance increased in the nine months ended September 30, 2013 to $207.2 million compared to $205.4 million in the same period in 2012. Investment interest expense decreased slightly to $6.9 million for the nine months ended September 30, 2013, compared to $7.0 million in 2012 due to a lower average cost of debt of 4.44% in 2013 as compared to 4.56% in 2012.

As a result of the higher investment interest income and slightly lower interest expense, net investment revenue increased by $2.9 million for the nine months ended September 30, 2013 compared to the same period in 2012.

Other Investment Revenue

Gain on securitization of receivables increased by $0.8 million to $2.8 million for the nine months ended September 30, 2013 compared to $2.0 million in the same period in 2012. Fee income decreased by approximately $9.8 million to $1.3 million for the nine months ended September 30, 2013 compared to $11.1 million for the nine months ended September 30, 2012 as a result of higher advisory fees in 2012 primarily due to sustainable infrastructure transactions in 2012.

Total Revenue, Net of Investment Interest Expense

Total revenue, net of investment interest expense declined by $6.1 million to $8.4 million for the nine months ended September 30, 2013 as compared to $14.5 million in the same period in 2012 as growth in net investment revenue of $2.9 million was offset by lower fee income included in the decline in other investment revenue totaling $9.0 million.

Other Expenses, Net

Other expenses, net increased by $2.7 million to $13.5 million in the nine months ended September 30, 2013, compared to $10.8 million in the same period in 2012, primarily as a result of increased compensation costs of $3.8 million. The increase in compensation costs was due to non-cash stock based compensation charges of $6.6 million in 2013, including a one-time charge of $5.8 million relating to the reallocation between the owners and employees of the equity interest of the Predecessor as part of the IPO and formation transactions, offset by a decline in higher performance based compensation expense associated with the higher fee income in 2012. The increased compensation costs were offset by lower general and administrative expenses which declined by $0.5 million to $2.8 million in the nine months ended September 30, 2013 and the elimination of the loss from equity method investment in affiliate of $0.5 million in 2012 as a result of the distribution of the investment in HA EnergySource on December 31, 2012 to the Company’s previous owners.

Non-GAAP Financial Measures

We consider the following non-GAAP financial measures useful to investors as key supplemental measures of our performance: (1) core earnings, (2) managed assets and (3) investment income from managed assets. These non-GAAP financial measures should be considered along with, but not as alternatives to, net income or loss as a measure of our operating performance. These non-GAAP financial measures, as calculated by us, may not be comparable to similarly named financial measures as reported by other companies that do not define such terms exactly as we define such terms.
