Non-GAAP Supplemental Financial Measures

Funds from Operations (FFO)

FFO is a widely recognized non-GAAP financial measure of REIT performance. The Company computes FFO in accordance with standards established by NAREIT, which may not be comparable to FFO reported by other REITs that do not compute FFO in accordance with the NAREIT definition, or that interpret the NAREIT definition differently than the Company does. The revised White Paper on FFO approved by the Board of Governors of NAREIT in April 2002, and subsequently amended, defines FFO as net income (loss) (computed in accordance with GAAP), excluding gains (or losses) from sales of properties, and real estate related impairment charges, plus real estate related depreciation and amortization and after adjustments for unconsolidated partnerships and joint ventures.

The Company presents FFO because it considers it an important supplemental measure of the Company’s operating performance and believes that it is frequently used by securities analysts, investors and other interested parties in the evaluation of REITs, particularly those that own and operate commercial office properties. The Company also uses FFO as one of several criteria to determine performance-based bonuses for members of its senior management. FFO is intended to exclude GAAP historical cost depreciation and amortization of real estate and related assets, which assumes that the value of real estate assets diminishes ratably over time. Historically, however, real estate values have risen or fallen with market conditions. Because FFO excludes depreciation and amortization unique to real estate, gains and losses from property dispositions, and real estate related impairment charges, it provides a performance measure that, when compared year over year, reflects the impact to operations from trends in occupancy rates, rental rates, operating costs, and interest costs, providing perspective not immediately apparent from net income. FFO does not represent cash generated from operating activities in accordance with GAAP and should not be considered as an alternative to net income (determined in accordance with GAAP), as an indication of the Company’s financial performance or to cash flow from operating activities (determined in accordance with GAAP) as a measure of the Company’s liquidity, nor is it indicative of funds available to fund the Company’s cash needs, including the Company's ability to make cash distributions.

Funds Available for Distribution (FAD)

FAD is a non-GAAP financial measure that is calculated as FFO plus non-real estate depreciation, allowance for straight line credit loss, adjustment for straight line operating lease rent, non-cash deferred compensation, and pro-rata adjustments from the Company's unconsolidated JVs, less straight line rental income, free rent net of amortization, second cycle tenant improvement and leasing costs, and recurring building improvements.

FAD is not intended to represent cash flow for the period and is not indicative of cash flow provided by operating activities as determined in accordance with GAAP. FAD is presented solely as a supplemental disclosure with respect to liquidity because the Company believes it provides useful information regarding the Company’s ability to fund its dividends. Because all companies do not calculate FAD the same way, the presentation of FAD may not be comparable to similarly titled measures of other companies. FAD does not represent cash flow from operating, investing and finance activities in accordance with GAAP and should not be considered as an alternative to net income (determined in accordance with GAAP), as an indication of the Company’s financial performance, as an alternative to net cash flows from operating activities (determined in accordance with GAAP), or as a measure of the Company’s liquidity.

Earnings Before Interest, Taxes, Depreciation and Amortization for Real Estate (EBITDAre)

EBITDAre is a non-GAAP financial measure. The Company computes EBITDAre in accordance with standards established by the National Association of Real Estate Investment Trusts, or NAREIT, which may not be comparable to EBITDAre reported by other REITs that do not compute EBITDAre in accordance with the NAREIT definition, or that interpret the NAREIT definition differently than the Company does. The White Paper on EBITDAre approved by the Board of Governors of NAREIT in September 2017 defines EBITDAre as net income (loss) (computed in accordance with Generally Accepted Accounting Principles, or GAAP), plus interest expense, plus income tax expense, plus depreciation and amortization, plus (minus) losses and gains on the disposition of depreciated property, plus impairment write-downs of depreciated property and investments in unconsolidated joint ventures, plus adjustments to reflect the entity's share of EBITDAre of unconsolidated joint ventures.

The Company presents EBITDAre because the Company believes that EBITDAre, along with cash flow from operating activities, investing activities and financing activities, provides investors with an additional indicator of the Company’s ability to incur and service debt. EBITDAre should not be considered as an alternative to net income (determined in accordance with GAAP), as an indication of the Company’s financial performance, as an alternative to net cash flows from operating activities (determined in accordance with GAAP), or as a measure of the Company’s liquidity.

Net Operating Income (NOI) and Cash NOI

NOI is a non-GAAP financial measure that is calculated as operating income before transaction related costs, gains/losses on early extinguishment of debt, marketing general and administrative expenses and non-real estate revenue. Cash NOI is also a non-GAAP financial measure that is calculated by subtracting free rent (net of amortization), straight-line rent, and the amortization of acquired above and below-market leases from NOI, while adding operating lease straight-line adjustment and the allowance for straight-line tenant credit loss.

The Company presents NOI and Cash NOI because the Company believes that these measures, when taken together with the corresponding GAAP financial measures and reconciliations, provide investors with meaningful information regarding the operating performance of properties. When operating performance is compared across multiple periods, the investor is provided with information not immediately apparent from net income that is determined in accordance with GAAP. NOI and Cash NOI provide information on trends in the revenue generated and expenses incurred in operating the Company's properties, unaffected by the cost of leverage, straight-line adjustments, depreciation, amortization, and other net income components. The Company uses these metrics internally as performance measures. None of these measures is an alternative to net income (determined in accordance with GAAP) and same-store performance should not be considered an alternative to GAAP net income performance.

Coverage Ratios

The Company presents fixed charge and debt service coverage ratios to provide a measure of the Company’s financial flexibility to service current debt amortization, interest expense and operating lease rent from current cash net operating income. These coverage ratios represent a common measure of the Company’s ability to service fixed cash payments; however, these ratios are not used as an alternative to cash flow from operating, financing and investing activities (determined in accordance with GAAP).

SL GREEN REALTY CORP.

NON-GAAP FINANCIAL MEASURES - DISCLOSURES

Funds from Operations (FFO)

FFO is a widely recognized non-GAAP financial measure of REIT performance. The Company computes FFO in accordance with standards established by NAREIT, which may not be comparable to FFO reported by other REITs that do not compute FFO in accordance with the NAREIT definition, or that interpret the NAREIT definition differently than the Company does. The revised White Paper on FFO approved by the Board of Governors of NAREIT in April 2002, and subsequently amended, defines FFO as net income (loss) (computed in accordance with GAAP), excluding gains (or losses) from sales of properties, and real estate related impairment charges, plus real estate related depreciation and amortization and after adjustments for unconsolidated partnerships and joint ventures.

The Company presents FFO because it considers it an important supplemental measure of the Company’s operating performance and believes that it is frequently used by securities analysts, investors and other interested parties in the evaluation of REITs, particularly those that own and operate commercial office properties. The Company also uses FFO as one of several criteria to determine performance-based bonuses for members of its senior management. FFO is intended to exclude GAAP historical cost depreciation and amortization of real estate and related assets, which assumes that the value of real estate assets diminishes ratably over time. Historically, however, real estate values have risen or fallen with market conditions. Because FFO excludes depreciation and amortization unique to real estate, gains and losses from property dispositions, and real estate related impairment charges, it provides a performance measure that, when compared year over year, reflects the impact to operations from trends in occupancy rates, rental rates, operating costs, and interest costs, providing perspective not immediately apparent from net income. FFO does not represent cash generated from operating activities in accordance with GAAP and should not be considered as an alternative to net income (determined in accordance with GAAP), as an indication of the Company’s financial performance or to cash flow from operating activities (determined in accordance with GAAP) as a measure of the Company’s liquidity, nor is it indicative of funds available to fund the Company’s cash needs, including the Company's ability to make cash distributions.

Funds Available for Distribution (FAD)

FAD is a non-GAAP financial measure that is calculated as FFO plus non-real estate depreciation, allowance for straight line credit loss, adjustment for straight line operating lease rent, non-cash deferred compensation, and pro-rata adjustments from the Company's unconsolidated JVs, less straight line rental income, free rent net of amortization, second cycle tenant improvement and leasing costs, and recurring building improvements.

FAD is not intended to represent cash flow for the period and is not indicative of cash flow provided by operating activities as determined in accordance with GAAP. FAD is presented solely as a supplemental disclosure with respect to liquidity because the Company believes it provides useful information regarding the Company’s ability to fund its dividends. Because all companies do not calculate FAD the same way, the presentation of FAD may not be comparable to similarly titled measures of other companies. FAD does not represent cash flow from operating, investing and finance activities in accordance with GAAP and should not be considered as an alternative to net income (determined in accordance with GAAP), as an indication of the Company’s financial performance, as an alternative to net cash flows from operating activities (determined in accordance with GAAP), or as a measure of the Company’s liquidity.

Earnings Before Interest, Taxes, Depreciation and Amortization for Real Estate (EBITDAre)

EBITDAre is a non-GAAP financial measure. The Company computes EBITDAre in accordance with standards established by the National Association of Real Estate Investment Trusts, or NAREIT, which may not be comparable to EBITDAre reported by other REITs that do not compute EBITDAre in accordance with the NAREIT definition, or that interpret the NAREIT definition differently than the Company does. The White Paper on EBITDAre approved by the Board of Governors of NAREIT in September 2017 defines EBITDAre as net income (loss) (computed in accordance with Generally Accepted Accounting Principles, or GAAP), plus interest expense, plus income tax expense, plus depreciation and amortization, plus (minus) losses and gains on the disposition of depreciated property, plus impairment write-downs of depreciated property and investments in unconsolidated joint ventures, plus adjustments to reflect the entity's share of EBITDAre of unconsolidated joint ventures.

The Company presents EBITDAre because the Company believes that EBITDAre, along with cash flow from operating activities, investing activities and financing activities, provides investors with an additional indicator of the Company’s ability to incur and service debt. EBITDAre should not be considered as an alternative to net income (determined in accordance with GAAP), as an indication of the Company’s financial performance, as an alternative to net cash flows from operating activities (determined in accordance with GAAP), or as a measure of the Company’s liquidity.

Net Operating Income (NOI) and Cash NOI

NOI is a non-GAAP financial measure that is calculated as operating income before transaction related costs, gains/losses on early extinguishment of debt, marketing general and administrative expenses and non-real estate revenue. Cash NOI is also a non-GAAP financial measure that is calculated by subtracting free rent (net of amortization), straight-line rent, and the amortization of acquired above and below-market leases from NOI, while adding operating lease straight-line adjustment and the allowance for straight-line tenant credit loss.

The Company presents NOI and Cash NOI because the Company believes that these measures, when taken together with the corresponding GAAP financial measures and reconciliations, provide investors with meaningful information regarding the operating performance of properties. When operating performance is compared across multiple periods, the investor is provided with information not immediately apparent from net income that is determined in accordance with GAAP. NOI and Cash NOI provide information on trends in the revenue generated and expenses incurred in operating the Company's properties, unaffected by the cost of leverage, straight-line adjustments, depreciation, amortization, and other net income components. The Company uses these metrics internally as performance measures. None of these measures is an alternative to net income (determined in accordance with GAAP) and same-store performance should not be considered an alternative to GAAP net income performance.

Coverage Ratios

The Company presents fixed charge and debt service coverage ratios to provide a measure of the Company’s financial flexibility to service current debt amortization, interest expense and operating lease rent from current cash net operating income. These coverage ratios represent a common measure of the Company’s ability to service fixed cash payments; however, these ratios are not used as an alternative to cash flow from operating, financing and investing activities (determined in accordance with GAAP).

The swaps have a weighted average interest rate of 1.6114%.

ESG Achievements

In April, the Company announced that it earned the WELL Health-Safety Rating across its entire 23 million square foot core portfolio, including at One Vanderbilt Avenue, one month after SL Green moved its headquarters into the sky-line defining tower in the heart of East Midtown. The WELL Health-Safety Rating is an evidence-based rating verified through the International WELL Building Institute (IWBI) that focuses on operational policies, maintenance protocols, stakeholder engagement, and emergency plans to address a post-COVID-19 environment.

Achieving the WELL Health-Safety Rating across the entire core portfolio is a testament to the effectiveness of SL Green’s response to the new operating conditions under COVID-19. The company is at the forefront of instituting new policies and initiatives to protect occupant health and to keep tenants and employees informed through a comprehensive COVID-19 plan called SL Green Forward. SL Green Forward is an extension of the company’s best-in-class operating platform to promote a high degree of safety, cleanliness, and wellness for all building occupants.

In April, the Company announced that it has received a 2021 ENERGY STAR Partner of the Year Sustained Excellence Award for the fourth consecutive year. This award honors organizations across the United States that have implemented distinguished corporate energy management programs. Less than one percent of 16,000 U.S. Environmental Protection Agency (EPA) partners achieve the Sustained Excellence distinction.

The U.S. Department of Energy and EPA awarded SL Green this award, the highest level of EPA recognition, for its extensive tenant outreach on energy efficiency, educational programs and widespread promotion of ENERGY STAR tools and best practices. As a continued leader in this space, SL Green achieved ENERGY STAR labels for over 14 buildings covering 10.6 million square feet across its industry-leading portfolio in 2020.

•Three monthly dividends on its outstanding common stock of $0.3033 per share which were paid on February 15, March 15, and April 15, 2021, equating to an annualized dividend of $3.64 per share of common stock; and

Non-GAAP Disclosures and Reconciliations Unaudited (Dollars in Thousands, except per share data)

Funds Available for Distribution (FAD)

FAD is a non-GAAP financial measure that is calculated as FFO plus non-real estate depreciation, allowance for straight line credit loss, adjustment for straight line operating lease rent, non-cash deferred compensation, and pro-rata adjustments from the Company's unconsolidated JVs, less straight line rental income, free rent net of amortization, second cycle tenant improvement and leasing costs, and recurring building improvements.

FAD is not intended to represent cash flow for the period and is not indicative of cash flow provided by operating activities as determined in accordance with GAAP. FAD is presented solely as a supplemental disclosure with respect to liquidity because the Company believes it provides useful information regarding the Company’s ability to fund its dividends. Because all companies do not calculate FAD the same way, the presentation of FAD may not be comparable to similarly titled measures of other companies. FAD does not represent cash flow from operating, investing and finance activities in accordance with GAAP and should not be considered as an alternative to net income (determined in accordance with GAAP), as an indication of the Company’s financial performance, as an alternative to net cash flows from operating activities (determined in accordance with GAAP), or as a measure of the Company’s liquidity.

Earnings Before Interest, Taxes, Depreciation and Amortization (EBITDAre)

EBITDAre is a non-GAAP financial measure. The Company computes EBITDAre in accordance with standards established by the National Association of Real Estate Investment Trusts, or NAREIT, which may not be comparable to EBITDAre reported by other REITs that do not compute EBITDAre in accordance with the NAREIT definition, or that interpret the NAREIT definition differently than the Company does. The White Paper on EBITDAre approved by the Board of Governors of NAREIT in September 2017 defines EBITDAre as net income (loss) (computed in accordance with Generally Accepted Accounting Principles, or GAAP), plus interest expense, plus income tax expense, plus depreciation and amortization, plus (minus) losses and gains on the disposition of depreciated property, plus impairment write-downs of depreciated property and investments in unconsolidated joint ventures, plus adjustments to reflect the entity's share of EBITDAre of unconsolidated joint ventures.

The Company presents EBITDAre because the Company believes that EBITDAre, along with cash flow from operating activities, investing activities and financing activities, provides investors with an additional indicator of the Company’s ability to incur and service debt. EBITDAre should not be considered as an alternative to net income (determined in accordance with GAAP), as an indication of the Company’s financial performance, as an alternative to net cash flows from operating activities (determined in accordance with GAAP), or as a measure of the Company’s liquidity.

Net Operating Income (NOI) and Cash NOI

NOI is a non-GAAP financial measure that is calculated as operating income before transaction related costs, gains/losses on early extinguishment of debt, marketing general and administrative expenses and non-real estate revenue. Cash NOI is also a non-GAAP financial measure that is calculated by subtracting free rent (net of amortization), straight-line rent, and the amortization of acquired above and below-market leases from NOI, while adding operating lease straight-line adjustment and the allowance for straight-line tenant credit loss.

The Company presents NOI and Cash NOI because the Company believes that these measures, when taken together with the corresponding GAAP financial measures and reconciliations, provide investors with meaningful information regarding the operating performance of properties. When operating performance is compared across multiple periods, the investor is provided with information not immediately apparent from net income that is determined in accordance with GAAP. NOI and Cash NOI provide information on trends in the revenue generated and expenses incurred in operating the Company's properties, unaffected by the cost of leverage, straight-line adjustments, depreciation, amortization, and other net income components. The Company uses these metrics internally as performance measures. None of these measures is an alternative to net income (determined in accordance with GAAP) and same-store performance should not be considered an alternative to GAAP net income performance.

Coverage Ratios

The Company presents fixed charge and debt service coverage ratios to provide a measure of the Company’s financial flexibility to service current debt amortization, interest expense and operating lease rent from current cash net operating income. These coverage ratios represent a common measure of the Company’s ability to service fixed cash payments; however, these ratios are not used as an alternative to cash flow from operating, financing and investing activities (determined in accordance with GAAP).
