We completed approximately $649 million and $1.5 billion of transactions during the three and nine months ended September 30, 2025, respectively, compared to approximately $396 million and $1.2 billion during the same period in 2024, respectively. As of September 30, 2025 we held approximately $7.5 billion of transactions on our balance sheet, which we refer to as our “Portfolio.” As of September 30, 2025, our Portfolio consisted of over 600 assets and we seek to manage the diversity of our Portfolio by, among other factors, project type, project operator, type of investment, type of technology, transaction size, geography, obligor and maturity. For those transactions that we choose not to hold on our balance sheet, we transfer all or a portion of the economics of the transaction, typically using securitization trusts, to institutional investors in exchange for cash and/or residual interests in the assets and in some cases, ongoing fees. As of September 30, 2025, we managed approximately $7.5 billion in assets in these securitization trusts or vehicles that are not consolidated on our balance sheet. When combined with our Portfolio, as of September 30, 2025, we manage approximately $15 billion of assets which we refer to as our “Managed Assets.”

We believe we have available a broad range of financing sources as part of our strategy to fund our investments. We finance our business through cash on hand, debt which may be either unsecured or secured, with or without recourse, and either fixed-rate or floating-rate, or equity. We may also decide to finance such transactions through the use of off-balance sheet securitization, syndication, or co-investment structures. Our revolving line of credit and our commercial paper programs allow us flexibility with regards to the timing of long-term capital markets transactions. We manage the interest rate risk associated with debt issuances through hedging activities, including the use of interest rate swaps. When issuing debt, we generally provide the estimated carbon emission savings using CarbonCount. In addition, certain of our debt issuances meet the environmental eligibility criteria for green bonds as defined by the International Capital Markets Association’s Green Bond Principles, which we believe makes our debt more attractive for certain investors compared to such offerings that do not qualify under these principles. We have an active strategic partnership with KKR where we jointly invest in eligible projects, and we may consider further use of similar structures to allow us to expand the investments that we make or to manage our Portfolio diversification.

We have a large and active pipeline of potential new opportunities that are in various stages of our underwriting process. We refer to potential opportunities as being part of our pipeline if we have determined that the project fits within our investment strategy and exhibits the appropriate risk and reward characteristics through an initial credit analysis, including a quantitative and qualitative assessment of the opportunity, as well as research on the relevant market and sponsor. Our pipeline of transactions that could potentially close in the next 12 months consists of opportunities in which we will be the lead originator as well as opportunities in which we may participate with other institutional investors. There can be no assurance with regard to any specific terms of such pipeline transactions or that any or all of the transactions in our pipeline will be completed. As of September 30, 2025, our pipeline consisted of more than $6.0 billion in new equity, debt and real estate opportunities. Of our pipeline, approximately 39% is related to BTM assets, 38% is related to GC assets, and 18% are related to FTN assets, with the remainder related to “Next Frontier” assets, which represent opportunities in burgeoning markets where potential investments align with our investment strategy.

•Net income increased by $104 million due primarily to an increase in income from equity method investments of $148 million and an increase in revenue of $21 million, offset by an increase in total expenses of $23 million, and a $42 million increase in income tax expense.

Current wording

•Net income decreased by $132 million due primarily to a decrease in income (loss) from equity method investments of $167 million and an increase in total expenses of $47 million, offset by an increase in revenue of $27 million and a $55 million decrease in income tax expense.

Previous wording

•Total revenue increased by $3 million due to increases in interest and rental income, management fees and retained interest income and origination fee and other income. Interest and rental income increased due to a higher average Portfolio balance. Management fees and retained interest income and origination fee and other income increases were driven by increased investment in a co-investment structure. These were partially offset by an $11 million decrease in gain on sale of assets, driven by a change in the mix and timing of assets being securitized, including the balance sheet rotation of certain land and government receivable assets in the prior period which did not recur.

Current wording

•Total revenue increased by $27 million due to an increase in interest and rental income of $16 million caused by a higher average asset balance and asset yield, a $4 million increase in gain on sale of assets driven by a change in the mix of assets being securitized, a $4 million increase in origination fee and other income due to a structuring advisory fee recognized, and a $3 million increase in management fees and retained interest income due to a larger fee-earning Managed Assets balance.

Previous wording

•Interest expense increased by $12 million due to a larger average outstanding debt balance and a higher average interest rate. We recorded a $3 million provision for loss on receivables and retained interests in securitization trusts, driven primarily by loan and loan commitments made during the period.

Current wording

•Interest expense increased by $35 million due to $19 million in redemption fees and the expensing of capitalized debt issuance costs associated with our redemption of the 2027 Senior Notes, as well due to a larger average outstanding debt balance and a higher average interest rate driven by the issuance of Junior Subordinated Notes that bear a higher interest rate but which reduce our need to issue equity to maintain our desired financial leverage ratio as a result of the partial equity treatment of these instruments by rating agencies. We recorded a $5 million provision for loss on receivables and retained interests in securitization trusts, driven primarily by a loan-specific reserve where the underlying assets are experiencing project-specific technical challenges which are currently in the process of being remediated.

Cash from Operations plus Other Portfolio Collections. These non-GAAP financial measures should be considered along with, but not as alternatives to, net income or loss as measures 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.

Current wording

We consider the following non-GAAP financial measures useful to investors as key supplemental measures of our performance: (1) Adjusted Earnings, (2) Adjusted Recurring Net Investment Income, (3) Managed Assets, and (4) Adjusted Cash from Operations plus Other Portfolio Collections. These non-GAAP financial measures should be considered along with, but not as alternatives to, net income or loss as measures of our operating performance.

We calculate Adjusted Earnings as GAAP net income (loss) excluding non-cash equity expense, provisions for loss on receivables, amortization of intangibles, non-cash provision (benefit) for taxes, losses (gains) from modification or extinguishment of debt facilities, non-cash tax charges and the earnings attributable to our non-controlling interest of our Operating Partnership. We also make an adjustment to eliminate our portion of fees we earn from related-party co-investment structures, and for our equity method investments in the renewable energy projects as described below. We will use judgment in determining when we will reflect the losses on receivables in our Adjusted Earnings, and will consider certain circumstances such as the time period in default, sufficiency of collateral as well as the outcomes of any related litigation. In the future, Adjusted Earnings may also exclude one-time events pursuant to changes in GAAP and certain other adjustments as approved by a majority of our independent directors.

The application of the HLBV method described above results in GAAP income or loss in any one period that is often significantly different from the economic returns achieved from the investment in any one period as a result of the impact of tax allocations, the high levels of depreciation and other non-cash expenses that are common to renewable energy projects and the differences between the agreed upon profit and loss and the cash flow allocations. Thus, in calculating Adjusted Earnings, we adjust GAAP net income (loss) for certain of our investments where there are characteristics as described above to take into account our calculation of the return on capital (based upon the underwritten investment rate), as adjusted to reflect the performance of the project and the cash distributed. In calculating the underwritten investment rate, we make certain assumptions, including the timing and amounts of cash flows generated by our investments, which may differ from actual results, and may update this yield to reflect our most current estimates of project performance. We believe this equity method investment adjustment to our GAAP net income (loss) in calculating our Adjusted Earnings measure is an important supplement to the income (loss) from equity method investments as determined under GAAP that helps investors understand the economic performance of these investments where HLBV income can differ substantially from the economic returns in any one period.

As it relates to Convertible Notes, we will assess the market characteristics around the instrument to determine if it is more akin to debt or equity based on the value of the underlying shares compared to the conversion price. If the instrument is more debt-like then we will include any related interest expense and exclude the underlying shares issuable upon conversion of the instrument. If the instrument is more equity-like and is more dilutive when treated as equity then we will exclude any related interest expense and include the weighted average shares underlying the instrument. We will consider the impact of any capped calls in assessing whether an instrument is equity-like or debt-like.

We believe that the aggregate of these items, which combine as a non-GAAP financial measure titled Adjusted Cash from Operations plus Other Portfolio Collections, is a useful measure of the liquidity we have available from our assets to fund both new investments and our regular quarterly dividends. This non-GAAP financial measure may not be comparable to similarly titled or other similar measures used by other companies. Although there is also not a directly comparable GAAP measure that demonstrates how we consider cash available for dividend payment, below is a reconciliation of this measure to Net cash provided by operating activities.

Adjusted Cash from Operations plus Other Portfolio Collections also differs from Net cash provided by (used in) investing activities in that it excludes many of the uses of cash used in our investing activities such as Equity method investments, Purchases of and investments in receivables, Purchases of debt securities, and Collateral provided to and received from hedge counterparties. In addition, Adjusted Cash from Operations plus Other Portfolio Collections is not comparable to Net cash provided by (used in) financing activities in that it excludes many of our financing activities such as proceeds from common stock issuances and borrowings and repayments of unsecured debt. We evaluate Adjusted Cash from Operations plus Other Portfolio Collections on a trailing twelve month (“TTM”) basis, as cash collections during any one quarter may not be comparable to other single quarters due to, among other reasons, the seasonality of projects operations and the timing of disbursement and payment dates. Cash Available for Reinvestment is a non-GAAP measure which is calculated as Adjusted Cash from Operations Plus Other Portfolio Collections less dividend and distribution payments made during the period. We believe Cash Available for Reinvestment is useful as a measure of our ability to make incremental investments from reinvested capital after factoring in all necessary cash outflows to operate the business. Management uses Cash Available for Reinvestment in this way, and we believe that our investors use it in a similar fashion.

Previous wording

In addition to general operational obligations, which are typically paid as incurred, and dividends and distributions, which are declared by our board of directors quarterly, we have future cash needs related to the payments due at maturity of our Commercial Paper Notes, Senior Unsecured Notes, Convertible Notes and Term Loan facilities. We also have maturities related to our non-recourse debt. However, as it relates to the non-recourse debt, to the extent there are not sufficient cash flows received from investments pledged as collateral for such debt, the investor has no recourse against other corporate assets to recover any shortfalls and corporate cash contributions would not be required. As it relates to the Convertible Notes, those obligations may be settled at maturity with cash, or with the issuance of shares to the extent that the market price of our common stock exceeds the strike price on our Convertible Notes. For further information on our long-term debt, see Note 8 to our financial statements of this Form 10-Q.

During periods of market disruptions, certain sources of financing may be more readily accessible than others which may impact our financing decisions. Over time, as market conditions change, we may use other forms of debt and equity in addition to these financing arrangements.
