▪ Beginning with our Annual Report on Form 10-K for the year ended December 31, 2020, and for all subsequent reporting periods ending on or after December 31, 2020, we have elected to present Distributable Earnings, a measure that is not prepared in accordance with GAAP, as a supplemental method of evaluating our operating performance. Distributable Earnings replaces our prior presentation of Core Earnings with no changes to the definition. In order to maintain our status as a REIT, we are required to distribute at least 90% of our taxable income as dividends. Distributable Earnings is intended to serve as a general proxy for our taxable income, though it is not a perfect substitute for it, and, as such, is considered a key indicator of our ability to generate sufficient income to pay our common dividends and in determining the amount of such dividends, which is the primary focus of income-oriented investors who comprise a meaningful segment of our stockholder base. We believe providing Distributable Earnings on a supplemental basis to our net income (loss) and cash flow from operating activities, as determined in accordance with GAAP, is helpful to stockholders in assessing the overall performance of our business. ▪ We use Distributable Earnings to evaluate our performance excluding the effects of certain transactions and GAAP adjustments we believe are not necessarily indicative of our current loan portfolio and operations. For reporting purposes, we define Distributable Earnings as net income (loss) attributable to our stockholders, computed in accordance with GAAP, excluding: (i) non-cash equity compensation expense; (ii) depreciation and amortization; (iii) any unrealized gains (losses) or other similar non-cash items that are included in net income for the applicable reporting period (regardless of whether such items are included in other comprehensive income (loss) or in net income for such period); and (iv) certain non-cash items and one-time expenses. Distributable Earnings may also be adjusted from time to time for reporting purposes to exclude one-time events pursuant to changes in GAAP and certain other material non-cash income or expense items approved by a majority of our independent directors. The exclusion of depreciation and amortization from the calculation of Distributable Earnings only applies to debt investments related to real estate to the extent we foreclose upon the property or properties underlying such debt investments. Distributable Earnings 32

▪ While Distributable Earnings excludes the impact of the unrealized non-cash current provision for credit losses, we expect to only recognize such potential credit losses in Distributable Earnings if and when such amounts are deemed non- recoverable. This is generally at the time a loan is repaid, or in the case of foreclosure, when the underlying asset is sold, but nonrecoverability may also be concluded if, in our determination, it is nearly certain that all amounts due will not be collected. The realized loss amount reflected in Distributable Earnings will equal the difference between the cash received, or expected to be received, and the carrying value of the asset, and is reflective of our economic experience as it relates to the ultimate realization of the loan. During the three months ended March 31, 2021, we recorded a $9.1 million benefit from provision for credit losses, which has been excluded from Distributable Earnings consistent with other unrealized gains (losses) and other non-cash items pursuant to our existing policy for reporting Distributable Earnings as referenced above. ▪ Distributable Earnings does not represent net income (loss) or cash flow from operating activities and should not be considered as an alternative to GAAP net income (loss), or an indication of our GAAP cash flows from operations, a measure of our liquidity, or an indication of funds available for our cash needs. In addition, our methodology for calculating Distributable Earnings may differ from the methodologies employed by other companies to calculate the same or similar supplemental performance measures, and, accordingly, our reported Distributable Earnings may not be comparable to the Distributable Earnings reported by other companies. Distributable Earnings (cont’d) 33

Other Definitions 34 All-in Yield at Origination ▪ Provided for illustrative purposes only. Calculations of all-in yield at origination are based on a number of assumptions (some or all of which may not occur) and are expressed as monthly equivalent yields that include net origination fees and exit fees and exclude future fundings and any potential or completed loan amendments or modifications. Calculations of all-in weighted average yield at origination exclude fixed rate loans. Cash Coupon ▪ Cash coupon does not include origination or exit fees. Future Fundings ▪ Fundings to borrowers of loan principal balances under existing commitments on our loan portfolio. Initial LTV ▪ The initial loan amount (plus any financing that is pari passu with or senior to such loan) divided by the as is appraised value (as determined in conformance with USPAP) as of the date the loan was originated set forth in the original appraisal. Net Income Attributable to Common Stockholders ▪ GAAP net income (loss) attributable to our common stockholders after deducting dividends attributable to our cumulative redeemable preferred stock. Original Term (Years) ▪ Original term (Years) is the initial maturity date at origination and does not include any extension options and has not been updated to reflect any subsequent extensions or modifications, if applicable. Recourse Leverage ▪ Borrowings outstanding on repurchase facilities, asset-specific financings, convertible senior notes and senior secured term loan facilities, less cash, divided by total stockholders’ equity. Senior Loans ▪ “Senior” means a loan primarily secured by a first priority lien on commercial real property and related personal property and also includes, when applicable, any companion subordinate loans. Stabilized LTV ▪ The fully funded loan amount (plus any financing that is pari passu with or senior to such loan), including all contractually provided for future fundings, divided by the as stabilized value (as determined in conformance with USPAP) set forth in the original appraisal. As stabilized value may be based on certain assumptions, such as future construction completion, projected re-tenanting, payment of tenant improvement or leasing commissions allowances or free or abated rent periods, or increased tenant occupancies. Total Leverage ▪ Borrowings outstanding on repurchase facilities, securitized debt obligations, asset-specific financings, convertible senior notes and senior secured term loan facilities, less cash, divided by total stockholders’ equity.
