EXPLANATORY NOTE

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. The Company, which is self-advised and self-administered, was incorporated in the state of Maryland on November 7, 2012, and intends to elect and qualify as a real estate investment trust (“REIT”) for U.S. federal income tax purposes commencing with our taxable year ending December 31, 2013.

Hannon Armstrong Capital, LLC, a Maryland limited liability company, the entity that operated our historical business prior to the consummation of our initial public offering on April 23, 2013 (our “IPO”) and which we refer to as the “Predecessor,” became our subsidiary upon consummation of our IPO. To the extent any of the financial data included in this Quarterly Report on Form 10-Q is as of a date or from a period prior to the consummation of our IPO, 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 our company’s results of operations, cash flows or financial position following the completion of the IPO.

In this Quarterly Report on Form 10-Q, unless specifically stated otherwise or the context otherwise indicates, references to “we,” “our,” “us,” “HASI,” and “our company” refer to Hannon Armstrong Sustainable Infrastructure Capital, Inc., a Maryland corporation, Hannon Armstrong Sustainable Infrastructure, L.P., and any of our other subsidiaries. Hannon Armstrong Sustainable Infrastructure, L.P. is a Delaware limited partnership of which we are the sole general partner and to which we refer in this Quarterly Report on Form 10-Q as our “Operating Partnership.”

FORWARD-LOOKING STATEMENTS

We make forward-looking statements in this Quarterly Report on Form 10-Q within the meaning of Section 27A of the Securities Act of 1933, as amended (the “Securities Act”), and Section 21E of the Securities Exchange Act of 1934, as amended (the “Exchange Act”) that are subject to risks and uncertainties. For these statements, we claim the protections of the safe harbor for forward-looking statements contained in such Sections. These forward-looking statements include information about possible or assumed future results of our business, financial condition, liquidity, results of operations, plans and objectives. When we use the words “believe,” “expect,” “anticipate,” “estimate,” “plan,” “continue,” “intend,” “should,” “may” or similar expressions, we intend to identify forward-looking statements.

Forward-looking statements are subject to significant risks and uncertainties. Investors are cautioned against placing undue reliance on such statements. Actual results may differ materially from those set forth in the forward-looking statements. Factors that could cause actual results to differ materially from those described in the forward-looking statements are contained in our Annual Report on Form 10-K for the fiscal year ended December 31, 2013 (our “2013 Form 10-K”) that was filed with the U.S. Securities and Exchange Commission (the “SEC”), and include risks discussed in MD&A of this report and in other periodic reports that we file with the SEC. Statements regarding the following subjects, among others, may be forward-looking:

Forward-looking statements are based on beliefs, assumptions and expectations as of the date of this report. We disclaim any obligation to publicly release the results of any revisions to these forward-looking statement. Any forward-looking statement speaks only as of the date on which it is made. New risks and uncertainties arise over time, and it is not possible for us to predict those events or how they may affect us. Except as required by law, we are not obligated to, and do not intend to, update or revise any forward-looking statements after the date of this report, whether as a result of new information, future events or otherwise.

The risks included here are not exhaustive. Other sections of this Quarterly Report on Form 10-Q or our 2013 Form 10-K may include additional factors that could adversely affect our business and financial performance. Moreover, we operate in a very competitive and rapidly changing environment. New risk factors emerge from time to time and it is not possible for management to predict all such risk factors, nor can it assess the impact of all such risk factors on our business or the extent to which any factor, or combination of factors, may cause actual results to differ materially from those contained in any forward-looking statements. Given these risks and uncertainties, investors should not place undue reliance on forward-looking statements as a prediction of actual results.

The following discussion is a supplement to and should be read in conjunction with our 2013 Form 10-K.

NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

(UNAUDITED)

MARCH 31, 2014

1. The Company

Hannon Armstrong Sustainable Infrastructure Capital, Inc. (“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. The Company and its subsidiaries are hereafter referred to as “we,” “us,” or “our.”

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 to us from the IPO were approximately $160.0 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 us 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, we 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 the Company.

We intend to elect and qualify to be taxed as real estate investment trust (“REIT”) for U.S. federal income tax purposes, commencing with our taxable year ended December 31, 2013. We generally will not be subject to U.S. federal income taxes on our taxable income to the extent that we annually distribute all of our taxable income to stockholders and maintain our qualification as a REIT. We operate our business through, and serve as the sole general partner of, our Operating Partnership subsidiary, Hannon Armstrong Sustainable Infrastructure, L.P, (the “Operating Partnership”) which was formed to acquire and directly or indirectly own the Company’s assets. We also intend to operate our business in a manner that will continue to permit us to maintain our exception from registration as an investment company under the 1940 Act.

To the extent any of the financial data included in this 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 our business as a result of the capital raised in the IPO, including the broadened scope of projects targeted for financing, our enhanced financial structuring flexibility and our ability to retain a larger share of the economics from our 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.

Our and our subsidiaries’ principal business is providing or arranging financing of sustainable infrastructure projects. We finance our business through the use of our own capital and debt, the securitization of receivables and the use of nonrecourse debt. We also generate 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 our managed assets. Some of our 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 that, 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

- 5 -

Table of Contents

accordance with U.S. generally accepted accounting principles (“U.S. GAAP”) requires management to make 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. Certain amounts in the prior year have been reclassified to conform to the current year presentation.

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

Following the guidance for non-controlling interests in Financial Accounting Standards Board (“FASB”) Accounting Standards Codification (“ASC”) 810, Consolidation, references in this report to our earnings per share and our net income and shareholders’ equity attributable to common shareholders do not include amounts attributable to non-controlling interests.

Table of Contents

Financing Receivables

Financing receivables include financing sustainable infrastructure project loans, receivables and direct financing leases. We account for leases as direct financing leases in accordance with ASC 840, Leases.

Unless otherwise noted, we generally have the ability and intention to hold our financing receivables for the foreseeable future and thus they are classified as held for investment. Our intent and ability to hold certain loans may change from time to time depending on a number of factors, including economic, liquidity and capital conditions. A financing receivable held for investment 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 effective interest method. Financing receivables that are held for investment are carried at cost, net of unamortized acquisition premiums or discounts, loan fees, and origination and acquisition costs as applicable, unless the loans are deemed impaired. Financing receivables that we intend to sell in the short-term are classified as held-for-sale and are carried at the lower of amortized costs or fair value on our balance sheet. We may secure non-recourse debt with the proceeds from our financing receivables.

We evaluate our financing receivables for potential delinquency or impairment on at least a quarterly basis and more frequently when economic or other conditions warrant such an evaluation. 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 consider the financing receivable delinquent or impaired and 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, we will remove it from non-accrual status.

A financing receivable is also considered impaired as of the date when, based on current information and events, it is determined that it is probable that we will be unable to collect all amounts due from the borrower in accordance with the original contracted terms. Many of our financing receivables are secured by sustainable infrastructure projects. Accordingly, we regularly evaluate the extent and impact of any credit deterioration associated with the performance and/or value of the underlying project, as well as the financial and operating capability of the borrower, its sponsors or the obligor as well as any guarantors. We consider a number of qualitative and quantitative factors in our assessment, including, as appropriate, a project’s operating results, loan-to-value ratios and any cash reserves, the ability of expected cash from operations to cover the debt service requirements currently and into the future, key terms of the transaction, the ability of the borrower to refinance the loan, other credit support from the sponsor or guarantor and the project’s collateral value. In addition, we consider the overall economic environment, the sustainable infrastructure sector, the effect of local, industry, and broader economic factors, and the historical and anticipated trends in interest rates, defaults and loss severities for similar transactions.

If a loan is considered to be impaired, we record an allowance to reduce the carrying value of the loan to the present value of expected future cash flows discounted at the loan’s contractual effective rate or the amount realizable from other contractual terms such as the currently estimated fair market value of the collateral less estimated selling costs, if repayment is expected solely from the collateral. We charge off loans against the allowance when we determine the unpaid principal balance is uncollectible, net of recovered amounts.

Investments

Investments include debt or equity securities that meet the criteria of ASC 320, Investments—Debt and Equity Securities. Unless otherwise noted, we intend to hold debt securities to maturity and thus carry these securities on the balance sheet at amortized cost basis, which is initially at cost plus any premiums or less any discounts that are amortized or accreted from or into investment interest income using the effective interest method. Debt securities that we do not intend to hold to maturity are classified as available-for-sale and are carried at fair value on our balance sheet. Unrealized gains and losses on available-for-sale debt securities are recorded as a component of accumulated other comprehensive income (loss) in stockholders’ equity.

- 7 -

Table of Contents

We evaluate our investments for other than temporary impairment (“OTTI”) on at least a quarterly basis, and more frequently when economic or market conditions warrant such an evaluation. Our OTTI assessment is a subjective process requiring the use of judgments and assumptions. Accordingly, we regularly evaluate the extent and impact of any credit deterioration associated with the financial and operating performance and/or value of the underlying project. We consider a number of qualitative and quantitative factors in our assessment. We first consider the current fair value of the security and the duration of any unrealized loss. Other factors considered include changes in the credit rating, performance of the underlying project, key terms of the transaction and support provided by the sponsor or guarantor.

To the extent that we have identified an OTTI for a security and intend to hold the investment to maturity and we do not expect that we will be required to sell the security prior to recovery of the amortized cost basis, we recognize only the credit component of OTTI in earnings. We determine the credit component using the difference between the securities’ amortized cost basis and the present value of its expected future cash flows, discounted using the effective yield or its estimated collateral value. Any remaining unrealized loss due to factors other than credit, or the non-credit component, is recorded in accumulated other comprehensive income.

To the extent we hold investments with an OTTI and if we have made the decision to sell the security or it is more likely than not that we will be required to sell the security prior to recovery of its amortized cost basis, we recognize the entire portion of the impairment in earnings.

Securitization of Receivables

We have established various special purpose entities or securitization trusts for the purpose of securitizing certain financing receivables or other debt investments. We determined that the trusts used in 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 an analysis of the structure of the trusts, under U.S. GAAP, we have concluded that we are not the primary beneficiary of the trusts as we do not have power over the trusts’ significant activities. Therefore, we do not consolidate these trusts in our condensed 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 assets, which are carried on the condensed consolidated balance sheets as securitization assets.

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 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.

As described above, we initially account 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 servicing assets for impairment at each reporting date. If the amortized cost of servicing assets is greater than the estimated fair value, we will 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 condensed consolidated balance sheets. We generally do not sell our residual assets. 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 residual assets or if the fair value of our residual 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 assets and thus would be considered OTTI.

Servicing income is recognized as earned. Servicing assets are amortized in proportion to, and over the period of, estimated net servicing income, and are periodically 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, we calculate 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.

Modifications to Debt

We evaluate any modifications to our debt in accordance with the applicable guidance in ASC 470-50, Debt Modifications and Extinguishments. If the debt instruments are substantially different, the modification is accounted for in the same manner as a debt extinguishment (i.e., a major modification) and the fees paid are recognized as expense at the time of the modification. Otherwise, such fees are deferred and amortized as an adjustment of interest expense over the remaining term of the modified debt instrument using the interest method.

Cash and Cash Equivalents

Cash and cash equivalents 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 which approximates fair value.

Restricted Cash

Restricted cash include cash and cash equivalents set aside with certain lenders primarily to support deferred funding and other obligations outstanding at the balance sheet dates.

Income Taxes

We intend to elect and qualify to be taxed as a REIT for U.S. federal income tax purposes, commencing with our taxable year ended December 31, 2013. To qualify as a REIT, we must meet a number of organizational and operational requirements, including a requirement that we currently distribute at least 90% of our net taxable income, excluding capital gains, to our shareholders. We intend to meet the requirements for qualification as a REIT and to maintain such qualification. As a REIT, we are not subject to U.S. federal corporate income tax on that portion of net income that is currently distributed to our owners. However, our taxable REIT subsidiaries (“TRS”) will generally be subject to U.S. federal, state, and local income taxes as well as taxes of foreign jurisdictions, if any.

We account for income taxes of our TRS 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.

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 for the three months ended March 31, 2013, in the accompanying condensed consolidated financial statements, since our profits and losses were reported on the Predecessor’s members’ tax returns.

Table of Contents

We apply accounting guidance with respect to how uncertain tax positions should be recognized, measured, presented, and disclosed in the financial statements. This guidance requires the accounting and disclosure of tax positions taken or expected to be taken in the course of preparing our tax returns to determine whether the tax positions are “more likely than not” to be sustained by the applicable tax authority. We are required to analyze all open tax years, as defined by the statute of limitations, for all major jurisdictions, which includes U.S. federal and certain states. We have no examinations in progress, none are expected at this time, and years 2010 through 2013 are open. As of March 31, 2014 and December 31, 2013, we had no uncertain tax positions. Our policy is to recognize interest expense and penalties related to income tax matters as a component of other expense. There was no accrued interest and penalties as of March 31, 2014 and December 31, 2013, and no interest and penalties were recognized during the three months ended March 31, 2014 and 2013.

Equity-Based Compensation

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

At the time of completion of our IPO, we adopted our 2013 Equity Incentive Plan (the “2013 Plan”), which provides for grants of stock options, stock appreciation rights, restricted stock units, shares of restricted common stock, phantom shares, dividend equivalent rights, long-term incentive-plan units (“LTIP units”) and other restricted limited partnership units issued by our Operating Partnership and other equity-based awards. From time to time, we may award non-vested restricted shares as compensation to members of our senior management team, our independent directors, advisors, consultants and other personnel under our 2013 Plan. The shares issued under this plan vest over a period of time as determined by the board of directors at the date of grant. We recognize 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

We compute 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 12). 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

We provide and arrange debt and equity financing for sustainable infrastructure projects and report all of our activities as one business segment.

3. Fair Value Measurements

Fair value is defined as the price that would be received for an asset or paid to transfer a liability in an orderly transaction between market participants on the measurement date. The fair value accounting guidance provides a three-level hierarchy for classifying financial instruments. The levels of inputs used to determine the fair value of our financial assets and liabilities carried on the balance sheet at fair value and for those which only disclosure of fair value is required 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

- 10 -

Table of Contents

significant to the fair value measurement of that financial asset or liability. We use our judgment and consider factors specific to the financial assets and liabilities in determining the significance of an input to the fair value measurements. As of March 31, 2014 and December 31, 2013, only our residual assets, financing receivables held-for-sale and investments available-for-sale, if any, were 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:

Level 1—Quoted prices (unadjusted) in active markets that are accessible at the measurement date for assets or liabilities.

Level 2—Observable prices that are based on inputs not quoted on active markets, but corroborated by market data.

Level 3—Unobservable inputs are used when little or no market data is available.

Financing Receivables and Investments

The fair value of financing receivables and investments is measured using a discounted cash flow model and Level 3 unobservable inputs. The significant unobservable inputs used in the fair value determination of our 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.

- 11 -

Table of Contents

Credit Facility

The fair values of the credit facility are determined using a discounted cash flow model and Level 3 unobservable inputs. The significant unobservable inputs used in the fair value determination of our 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.

Asset-Backed Nonrecourse Notes and Other Nonrecourse Debt

The fair values of our 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 our 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.

Residual Assets

As of March 31, 2014 and December 31, 2013, we had residual assets, which are included in the securitization assets line item in the condensed consolidated balance sheets, relating to our 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 our residual assets are estimated securitization cash flows, potential default rates and comparable transactions in related assets of public companies. The observable inputs include published U.S government interest rates. 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 residual 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 our Level 3 assets carried at fair value, which consists of our residual assets:

Concentration of Credit Risk

Financial instruments that potentially subject us to concentrations of credit risk are principally cash and cash equivalents. As of March 31, 2014 and December 31, 2013, we had cash deposits held in U.S. banks of $82.6 million and $81.7 million, respectively. Included in these balances are $81.0 million and $80.3 million in bank deposits, respectively, in excess of amounts federally insured.

Financing receivables 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 our view, represent a significant concentration of credit risk. See Note 6 for an analysis by type of obligor.

4. Non-Controlling Interest

Non-Controlling Interest in Consolidated Entities

Units of limited partnership interests in the Operating Partnership (“OP units”) that are owned by other limited partners are included in non-controlling interest on our condensed consolidated balance sheets. As of March 31, 2014, the Operating Partnership had 16,848,540 OP units outstanding, of which 97.9% were owned by us and 2.1% were owned by other limited partners. The outstanding OP units held by outside limited partners are redeemable for cash, or at our option, for a like number of shares of our common stock.

In January 2014, we agreed to not exercise our right under the Operating Partnership agreement to deliver shares of our common stock in lieu of cash upon a request for redemption of OP units held by certain of our limited partners and instead agreed to redeem such OP units for cash until such time that we have an effective registration statement covering the OP units held by such limited partners. As a result, we are reporting the portion of our non-controlling interest that is redeemable for cash outside of equity as of March 31, 2014. During the three months ended March 31, 2014, we redeemed 112,577 OP units held by our non-controlling interest holders for cash of $1.5 million. Our non-controlling interest holders held 349,798 OP units as of March 31, 2014.

The following is an analysis of the controlling and non-controlling interest from December 31, 2013 to March 31, 2014:

Allocation of Profit and Loss and Cash Distributions prior to our IPO

Prior to the IPO, all profits, losses and cash distributions of the Predecessor were allocated based on the percentages as follows:

Upon the completion of the IPO, the Preferred Units and Common Units in the Predecessor were exchanged for shares of our common stock or OP units in the Operating Partnership, or for certain unit holders in the Predecessor, were redeemed for cash.

5. Securitization of Receivables

We sold financing receivables in securitization transactions, recognizing gains of $2.0 million for the three months ended March 31, 2014. We did not securitize any transactions during three months ended March 31, 2013. In connection with securitization transactions, we retained servicing responsibilities and residual assets. In certain instances, we receive annual servicing fees ranging from 0.05% to 0.20% of the outstanding balance. The investors and the securitization trusts have no recourse to our other assets for failure of debtors to pay when due. Our residual assets are subordinate to investors’ interests, and their values are subject to credit, prepayment and interest rate risks on the transferred financial assets.

The fair values of retained assets, including the discount rates used in valuing those assets and the sensitivity to an increase in the discount rates of 5% and 10%, as of March 31, 2014 and December 31, 2013, were as follows:

Table of Contents

In computing gains and losses on securitizations, 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, we do not currently expect to incur any credit losses on the receivables sold.

The following is an analysis of certain cash flows between us and the securitization trusts:

As of March 31, 2014 and December 31, 2013, our managed receivables totaled $2.1 billion, of which $1.6 billion were securitized. There were no securitization credit losses in the three months ended March 31, 2014 or 2013, and no material securitization delinquencies as of March 31, 2014 and December 31, 2013.

6. Financing Receivables and Investments

As of March 31, 2014, we held approximately $486.8 million of financing receivables and investments on our balance sheet, which we refer to as our portfolio. The financing receivables and investments are typically collateralized contractually committed debt 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.

The following is an analysis of financing receivables and investments by type of obligor and credit quality as of March 31, 2014.

Table of Contents

The components of financing receivables of March 31, 2014 and December 31, 2013, were as follows:

The following table provides a summary of our anticipated maturity dates of our financing receivables and investments for each range of maturities as of March 31, 2014:

Investments consist of debt securities that are classified as held-to-maturity and thus recorded at their amortized cost as of March 31, 2014. There were no investments in an unrealized loss position as of March 31, 2014, or December 31, 2013.

As of December 31, 2013, we classified as held-for-sale financing receivables of $24.8 million and a debt security of $3.2 million, which were sold in the first quarter of 2014. The financing receivables were securitized into our securitization trusts and the debt security was sold at its fair value, which approximated its carrying value.

In accordance with the terms of certain financing receivables purchase agreements, payments of the purchase price is scheduled to be made over time, generally within twelve months of entering into the transaction, and as a result, we have recorded deferred funding obligations of $64.8 million and $74.7 million as of March 31, 2014 and December 31, 2013, respectively. We have $43.0 million and $49.9 million in restricted cash as of March 31, 2014 and December 31, 2013, respectively, that will be used to pay these funding obligations.

Table of Contents

In December 2013, we recorded an allowance of $11.0 million on the remaining $11.8 million balance of a $24 million loan made in May 2013 to a wholly owned subsidiary of EnergySource LLC (“EnergySource”) to be used for a geothermal project. The loan’s average outstanding balance for the three months ended March 31, 2014 was $11.8 million. No interest income was accrued or collected in cash on the loan for the three months ended March 31, 2014. For the three months ended March 31, 2013, we recorded income from EnergySource for investment banking and management services of $0.1 million. The project is considered a variable interest entity and the maximum exposure to loss is the net balance of $0.8 million, which represents our current estimate of the realizable sale value of tangible project assets. As previously disclosed, certain of our executive officers and directors own an indirect minority interest in EnergySource following the distribution of the Predecessor’s ownership interest prior to our IPO. We are assessing various options intended to allow us to recover as much of the loan as possible.

We had no other financing receivables or investments on nonaccrual status as of March 31, 2014 and December 31, 2013. There was no provision for credit losses for the three months ended March 31, 2014, or March 31, 2013. We evaluate any modifications to our financing receivables in accordance with the guidance in ASC 310, Receivables. We evaluate modifications of financing receivables to determine if the modification is more than minor, whereby any related fees, such as prepayment fees, would be recognized in income at the time of the modification. We did not have any loan modifications that qualify as trouble debt restructurings for the three months ended March 31, 2014 or 2013.

7. Credit Facility

In 2013, we entered into a $350.0 million senior secured revolving credit facility through newly-created, wholly-owned special purpose subsidiaries (the “Borrowers”). On November 26, 2013, the PF Loan Agreement (as defined below) was amended to provide our company with the flexibility to negotiate an alternative interest rate margin on certain loans with the approval of the administration agent.

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 us, 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 us, with maximum total advances (without giving effect to prepayments or repayments) of $300 million. We, together with certain of our 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 the London Interbank Offered Rate (“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% or a specifically negotiated rate on certain loans as approved by the administrative agent.

Any financing we 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 in accordance with the Loan Agreement determines the borrowing capacity, subject to the overall facility limits described above.

- 17 -

Table of Contents

We had outstanding borrowings under our credit facilities of $117.1 million and $77.1 million as of March 31, 2014 and December 31, 2013, respectively. We pledged $190.0 million and $114.3 million of financing receivables as collateral for the credit facility as of March 31, 2014 and December 31, 2013, respectively. The weighted average short-term borrowing rate of our credit facilities was 2.5% and 2.6% as of March 31, 2014 and December 31, 2013, respectively. We incurred approximately $8.7 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 on a straight-line basis 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 that we maintain the following covenants:

We were in compliance with the financial covenants of the Loan Agreements at each reporting date that such covenants were applicable. For purposes of the Maximum Debt to Equity ratio, debt is defined as total indebtedness excluding accounts payable and accrued expenses and nonrecourse debt.

8. Nonrecourse Debt

Asset-Backed Nonrecourse Notes

In December 2013, through certain of our subsidiaries, we issued in a private placement $100.0 million of nonrecourse Asset-Backed Notes (the “Notes”) with a fixed interest rate of 2.79%. The Notes mature in December 2019 and are secured by certain of our on balance sheet financing receivables. The Noteholders can only look to the cash flows of the pledged financing receivables to satisfy the Notes and we are not liable for nonpayment by the obligor of the financing receivables securing these Notes. As of March 31, 2014 and December 31, 2013, we had $98.7 million and $100.1 million, respectively, of Notes outstanding, which were secured by $108.4 million and $109.5 million, respectively, of our on balance sheet financing receivables. Upon maturity, the Notes are anticipated to have an outstanding debt balance of approximately $57 million. The Notes may be prepaid prior to December 2018, with a make whole payment calculated using a discount rate equal to the comparable-maturity treasury yield plus 50 basis points. Thereafter the notes are repayable at par. At maturity, we will have the option to rollover the remaining debt with a mutually agreed term and rate or repay the outstanding balance.

- 18 -

Table of Contents

We incurred approximately $0.2 million of costs associated with the issuance of the Notes that have been capitalized (included in other assets on the condensed consolidated balance sheets) and will be amortized using the effective interest method over a 72 month period from December 2013.

Other Nonrecourse Debt

We have other nonrecourse debt that was used to finance certain of our financing receivables for the term of the financing receivable. Amounts due under nonrecourse notes are secured by financing receivables with a carrying value of $147.3 million and $156.4 million as of March 31, 2014 and December 31, 2013, respectively, and there is no recourse to our general assets. Debt service payment requirements, in a majority of cases, are equal to or less than the cash flows received from the underlying financing receivables.

Analyses of other nonrecourse debt by interest rate are as follows:

The stated minimum maturities of nonrecourse debt as of March 31, 2014, were as follows:

9. Commitments and Contingencies

Litigation

We are not currently subject to any legal proceedings that are likely to have a material adverse effect on our financial position, results of operations or cash flows.

10. Income Tax

We intend to elect and qualify to be taxed as a REIT, commencing with our taxable year ending December 31, 2013. As a REIT, we are not subject to federal corporate income tax on that portion of net income that is currently distributed to our owners. However, our TRS will generally be subject to federal, state, and local income taxes as well as taxes of foreign jurisdictions, if any.

- 19 -

Table of Contents

We account for income taxes of our TRS 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.

During the three months ended March 31, 2014, we transferred an asset to our TRS that had a tax basis in excess of its book basis. We recognized a deferred tax asset for the amount we expect to be realizable. Because the transfer was done amongst entities under common control, we recorded the $1.9 million impact of the transaction to additional paid in capital. We established a valuation allowance of $2.1 million against the remaining balance of our deferred tax asset as of March 31, 2014. We recorded income tax expense of $0.1 million for the three months ended March 31, 2014, related to the activities of our TRS. The income tax expense was determined using a federal rate of 35% and a combined state rate of 5%.

No provision for federal or state income taxes has been made for the three months ended March 31, 2013, since our profits and losses were reported on the Predecessor’s members’ tax returns.

11. Equity

Dividends and Distributions

Our board of directors declared the following dividends in 2013 and 2014:

Equity Incentive Plan

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

At the time of completion of our IPO, we adopted our 2013 Plan, which provides for grants of stock options, stock appreciation rights, restricted stock units, shares of restricted common stock, phantom shares, dividend equivalent rights, LTIP units and other restricted limited partnership units issued by our Operating Partnership and other equity-based awards. From time to time, we may award non-vested restricted shares as compensation to members of our senior management team, our independent directors, advisors, consultants and other personnel under our 2013 Plan. The shares issued under this plan vest over a period of time as determined by the board of directors at the date of grant. We recognize 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.

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 and the 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 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

- 20 -

Table of Contents

immediately vested, we recorded compensation expense related to these awards of $5.8 million on April 23, 2013. No tax benefits have been recorded related to this reallocation. The restricted stock units, net of applicable federal and state taxes withheld, were converted to common shares in November 2013.

Awards of Shares of Restricted Common Stock

On April 23, 2013, we granted, under the 2013 Plan, 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. The board of directors determines the vesting period for such shares at the date of grant. For shares issued, we recognize 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%.

For the three months ended March 31, 2014, we recorded $0.5 million of equity-based compensation expense. The total unrecognized compensation expense related to awards of shares of restricted common stock subject to a vesting schedule, considering estimated forfeitures, is $5.9 million as of March 31, 2014, which is expected to be recognized over a weighted-average term of approximately two years. No equity-based compensation awards vested as of March 31, 2014.

A summary of the non-vested shares of restricted common stock as of March 31, 2014, is as follows:

In April 2014, in accordance with our 2013 Plan, our board of directors awarded Long-term Incentive Plan awards (“LTIP” awards) of 336,272 restricted common shares to certain members of management. Vesting of the LTIP awards is contingent upon the later of the achievement of certain dividend growth targets and December 31, 2015. Our board of directors also awarded employees and directors 142,359 restricted common shares in accordance with our 2013 Plan, which vest in 2015 and 2016.

12. Earnings per Share of Common Stock

Net income or loss figures are presented net of income or loss attributable to the non-controlling OP units in the earnings per share calculations. The non-controlling limited partners’ outstanding OP units 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 attributable to the non-controlling interest was 361,414 for the three months ended March 31, 2014.

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 three months ended March 31, 2014, undistributed earnings attributable to unvested shares of restricted common stock have been excluded, as applicable, from net income or loss attributable to common shareholders used in the basic and diluted earnings per share calculations because the effect of these items on diluted earnings per share would be anti-dilutive. As of March 31, 2014, there were 605,815 shares of unvested restricted common stock.

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

Public Offering of Common Stock

On April 29, 2014, we sold in a public offering 5,750,000 shares of our common stock at $13.00 per share, less the underwriting discount and estimated expenses, for net proceeds of $70.3 million. This includes the exercise in full by the underwriters of their option to purchase an additional 750,000 shares of our common stock.

Item 2. Management’s Discussion and Analysis of Financial Condition and Results of Operations

In this Quarterly Report on Form 10-Q, unless specifically stated otherwise or the context otherwise indicates, references to “we,” “our,” “us,” “HASI,” and “our company” refer to Hannon Armstrong Sustainable Infrastructure Capital, Inc., a Maryland corporation, Hannon Armstrong Sustainable Infrastructure, L.P., and any of our other subsidiaries. Hannon Armstrong Sustainable Infrastructure, L.P. is a Delaware limited partnership of which we are the sole general partner and to which we refer in this Quarterly Report on Form 10-Q as our “Operating Partnership.”

Hannon Armstrong Capital, LLC, a Maryland limited liability company, the entity that operated our historical business prior to the consummation of our IPO and which we refer to as the “Predecessor,” became our subsidiary upon consummation of our IPO. To the extent any of the financial data included in this Quarterly Report on Form 10-Q is as of a date or from a period prior to the consummation of our IPO, 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 our company’s results of operations, cash flows or financial position following the completion of the IPO.

The following discussion is a supplement to and should be read in conjunction with the accompanying condensed consolidated financial statements and related notes and with our 2013 Form 10-K, that was filed with the SEC.

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, have provided or arranged over $4.6 billion of financing in more than 475 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.

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 of March 31, 2014, approximately 97% of the transactions held on our balance sheet are considered investment grade.

- 23 -

Table of Contents

On April 23, 2013, we completed our IPO in which we sold 13,333,333 shares of common stock at $12.50 per share. The common stock is listed on the NYSE under the symbol “HASI.” The net proceeds from our IPO were approximately $160.0 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 us upon the exercise by the underwriters of their option to purchase an additional 818,356 shares of common stock on May 23, 2013. On April 29, 2014, we sold in a public offering 5,750,000 shares of our common stock at $13.00 per share, less the underwriting discount and estimated expenses, for net proceeds of $70.3 million.

Our strategy in undertaking the public offerings 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. Prior to our IPO, we had traditionally financed our business by accessing the securitization market, primarily utilizing our relationships with institutional investors such as insurance companies and commercial banks. By utilizing the net proceeds from our offerings and our anticipated continued access to the public markets, our strategy is to hold a significantly larger portion of the loans or other assets we originate on our balance sheet, using our own capital in conjunction with both securitizations and other 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. While we expect our investment interest expense to increase, 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.

In our securitization transactions, including Hannie Mae, 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 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. We typically 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 that 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 may periodically provide other services, including arranging financings that are held on the balance sheet of other investors and advising various companies with respect to structuring investments.

From April 23, 2013, the date of our IPO, through March 31, 2014, we completed approximately $760 million of transactions, of which 52% are held on our balance sheet and 48% were securitized or syndicated. Approximately 62% of these transactions financed energy efficiency projects; approximately 33% financed clean energy projects, while the remaining 5% financed other sustainable infrastructure projects. The transactions that are held on our balance sheet have an average transaction size of approximately $17 million, a weighted average remaining life as of March 31, 2014, of approximately 9 years and are typically secured by the installed improvements that are the subject of the financing.

As of March 31, 2014, our on balance sheet portfolio, from which we earn investment income, was approximately $487 million. Approximately 94% of our on balance sheet portfolio consisted of fixed rate loans, direct financing leases or debt securities with the remaining 6% consisting of floating rate debt. Approximately 47%

- 24 -

Table of Contents

of our on balance sheet portfolio consisted of U.S. federal government obligations, 15% of obligations of state or local government or other institutions such as hospitals and universities and 38% were commercial obligations. In total, as of March 31, 2014, we managed approximately $2.1 billion of assets, which consisted of our on balance sheet portfolio plus approximately $1.6 billion of assets held in non-consolidated securitization trusts. We refer to this $2.1 billion of assets collectively as our managed assets.

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 for which we will either be the lead financier or projects in which we will participate that are originated by other institutional investors or intermediaries. As of March 31, 2014, our pipeline consisted of more than $2.0 billion in new financing opportunities. There can, however, be no assurance that any or all of the 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 registration as an investment company under the 1940 Act.

Critical Accounting Policies and Use of Estimates

The preparation of financial statements in accordance with U.S. GAAP requires management to make a number of judgments, estimates and assumptions that affect the reported amount of assets, liabilities, income and expenses in the consolidated financial statements. Understanding our accounting policies and the extent to which we use management judgment and estimates in applying these policies is integral to understanding our financial statements. We provide a summary of our significant accounting policies under “Note 2—Summary of Significant Accounting Policies” in our 2013 Form 10-K.

We have identified the following accounting policies as critical because they require significant judgments and assumptions about highly complex and inherently uncertain matters and the use of reasonably different estimates and assumptions could have a material impact on our reported results of operations or financial condition. These critical accounting policies govern:

We evaluate our critical accounting estimates and judgments on an ongoing basis and update them, as necessary, based on changing conditions.

We provide additional information on our critical accounting policies and use of estimates under “MD&A—Critical Accounting Policies and Use of Estimates” in our 2013 Form 10-K.

Results of Operations

Our strategy in undertaking our IPO was to expand our proven ability to serve the rapidly growing sustainable infrastructure market by increasing our capital resources, enhancing our financial and structuring flexibility, expanding the types of projects and end-customers we pursue, and selectively retaining a larger portion on balance sheet of the economics in the financings we originate. 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 March 31, 2014, our on balance sheet portfolio, from which we earn investment income, was approximately $487 million. Approximately 94% of our on balance sheet portfolio consisted of fixed rate loans, direct financing leases or debt securities with the remaining 6% consisting of floating rate debt. Approximately 47% of our on balance sheet portfolio consisted of U.S. federal government obligations, 15% of obligations of state or local government or other institutions such as hospitals and universities and 38% were commercial obligations. In total, as of March 31, 2014, we managed approximately $2.1 billion of assets, which consisted of our on balance sheet portfolio plus approximately $1.6 billion of assets held in non-consolidated securitization trusts. We refer to this $2.1 billion of assets collectively as our managed assets.

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 our 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 our results of operations, cash flows or financial position following the completion of our IPO transaction and in the future.

Our Portfolio

As of March 31, 2014, we held approximately $486.8 million of financing receivables and investments on our balance sheet, which we refer to as our portfolio. The financing receivables and investments are typically collateralized contractually committed debt 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.

The following is an analysis of financing receivables and investments by type of obligor and credit quality as of March 31, 2014.

Comparison of the Three Months Ended March 31, 2014 vs. Three Months Ended March 31, 2013

Net Income

Net income increased by $4.0 million to $2.8 million for the three months ended March 31, 2014, compared to a loss of $1.2 million for the same period in 2013. This increase was primarily the result of a $4.9 million increase in Total Revenue, net of investment interest expense and provision that was driven primarily by an increase in our on-balance sheet portfolio of financing receivables and investments and higher fee income, partially offset by an increase in Other Expenses, net of $0.9 million driven by higher compensation and benefits costs driven by an increase in equity-based compensation and higher general and administrative expenses related to higher legal, consulting and accounting costs associated with being a public company during the three months ended March 31, 2014, compared to the same period in 2013. Net income during the three months ended March 31, 2014, was also unfavorably impacted by income tax expense of $0.1 million related to our TRS activities.

Net Investment Revenue

Net investment revenue increased to $2.4 million in the three months ended March 31, 2014 from $0.5 million in the same period in 2013. The increase was driven primarily by an increase our on-balance sheet portfolio of financing receivables and investments held during the three months ended March 31, 2014, when compared to the same period in 2013. The monthly average balance of our on-balance sheet portfolio increased to approximately $445 million in the three months ended March 31, 2014 from approximately $189 million in the same period in 2013. This increase in our on-balance sheet portfolio is driven by our strategy to hold more originated transactions on our balance sheet to increase our shareholders’ value. The increase in our on-balance portfolio was partially offset by a decline in average interest rates earned on these assets, which decreased to 5.31% in the three months ended March 31, 2014 from 5.73% in the same period in 2013. This decrease was driven primarily by the impact of the current lower interest rate environment as compared to the historical rate environment when our legacy portfolio was originated. Our larger on-balance sheet portfolio, partially offset by lower interest rates, generated a $3.2 million increase in investment interest income to $5.9 million during the three months ended March 31, 2014, compared to $2.7 million during the same period in 2013.

As we have increased our leverage, including the use of our 2.79% fixed rate asset backed debt, to finance our on-balance portfolio, the monthly average debt balance increased in the three months ended March 31, 2014 to approximately $344 million compared to approximately $194 million during the same period in 2013. This increase in our monthly average debt balance was the primary driver for the increase in our investment interest expense of $1.3 million, when comparing the three months ended March 31, 2014 to the same period ended March 31, 2013. Our average debt rate decreased to 4.10% during the three months ended March 31, 2014, from 4.62% for the same period ending March 31, 2013, due to the lower interest rates on our credit facility and the our asset backed debt as compared to our historical match funded other nonrecourse debt.

As a result of the increase in our on-balance sheet portfolio of financing receivables and investments offset by an increase in the debt used to financing the acquisition of the on-balance sheet portfolio, net investment revenue increased over 400% to $2.4 million for the three months ended March 31, 2014, from $0.5 million for the same period ended in 2013.

Other Investment Revenue

Gain on securitization of receivables increased by $2.0 million for the three months ended March 31, 2014, when compared to the same period ended March 31, 2013. The increase was the result of higher transaction volume in 2014 when compared to 2013. Fee income also increased by $1.1 million to $1.3 million for the three months ended March 31, 2014, from $0.3 million for the three months ended March 31, 2013, primarily as a result of an increase in the volume of syndication fee transactions closed in 2014 when compared to such transactions closed in 2013.

Total Revenue, Net of Investment Interest Expense and Provision

Total revenue, net of investment interest expense and provision increased by $4.9 million to $5.7 million for the three months ended March 31, 2014, compared to $0.8 million for the same period in 2013. This increase was primarily a result of the increase in net investment revenues due to an increase in our on-balance sheet portfolio of financing receivables and investments and higher transaction volumes driving the increases in other investment revenue when comparing the three months ended March 31, 2014 to the same period ended March 31, 2013.

Other Expenses, Net

Other expenses, net increased by $0.8 million to $2.8 million in the three months ended March 31, 2014, compared to $2.0 million in the same period in 2013, primarily as a result of higher compensation and benefits costs of $0.5 million and higher general and administrative expenses of $0.5 million partially offset by lower depreciation and amortization and other interest expenses.

Compensation and benefits increased $0.5 million to $1.6 million due primarily to higher equity-based compensation expenses in 2014 related to our 2013 Plan, which was implemented on April 23, 2013, our IPO date. General and administrative expenses also increased by $0.5 million to $1.2 million in the three months ended March 31, 2014 from $0.7 million in the same period in 2013. This increase was primarily due to higher professional fees in 2014 related to the being a public company.

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.

Core Earnings

We calculate Core Earnings as U.S. GAAP net income (loss) excluding non-cash equity compensation expense, non-cash provision for credit losses, amortization of intangibles and any non-cash tax charges. The amount is also adjusted to exclude one-time events pursuant to changes in U.S. GAAP and certain other non-cash charges as approved by a majority of our independent directors.

We believe that Core Earnings provides an additional measure of our core operating performance by eliminating the impact of certain non-cash expenses and facilitating a comparison of our financial results to those of other comparable REITs with fewer or no non-cash charges and comparison of our own operating results from period to period. Our management uses Core Earnings in this way. We believe that our investors also use Core Earnings, or a comparable supplemental performance measure, to evaluate and compare our performance to that of our peers, and as such, we believe that the disclosure of Core Earnings is useful to (and expected by) our investors.

However, Core Earnings does not represent cash generated from operating activities in accordance with U.S. GAAP and should not be considered as an alternative to net income (determined in accordance with U.S. GAAP), or an indication of our cash flow from operating activities (determined in accordance with U.S. GAAP), a measure of our liquidity, or an indication of funds available to fund our cash needs, including our ability to make cash distributions. In addition, our methodology for calculating Core Earnings may differ from the methodologies employed by other REITs to calculate the same or similar supplemental performance measures, and accordingly, our reported Core Earnings may not be comparable to the core earnings reported by other REITs.

We have calculated our Core Earnings for the three months ended March 31, 2014. We did not use Core Earnings and thus have not calculated it for periods prior to our IPO. The table below provides a reconciliation of our U.S. GAAP net income to Core Earnings:

Managed Assets and Investment Income from Managed Assets

As we both consolidate assets on our balance sheet and securitize investments, certain of our financing receivables and other assets are not reflected on our balance sheet where we may have a residual interest in the performance of the investment. Thus, we also calculate both our investments and our income on our investments on a non-GAAP “managed” basis, which assumes that securitized loans are not sold, with the effect that the income from securitized loans is included in our income in the same manner as the income from loans that we consolidated on our balance sheet. We believe that our managed basis information is useful to investors because it portrays the results of both on and off balance sheet loans that we manage, which enables investors to understand and evaluate the credit performance associated with the portfolio of loans reported on our condensed consolidated balance sheet and our retained interests in securitized loans. Our non-GAAP managed basis measures may not be comparable to similarly titled measures used by other companies.

The following is a reconciliation of our U.S. GAAP financing receivables and investments to our managed assets as of March 31, 2014 and December 31, 2013, and our U.S. GAAP income from financing receivables to our investment income from managed assets for the three months ended March 31, 2014 and 2013:
