Investment Activity

As previously disclosed, in the first quarter, Digital Realty successfully resolved its relationship with Cyxtera, with the closing of a series of transactions with Brookfield Infrastructure Partners L.P., Cyxtera Technologies and Digital Core REIT. Digital Realty received $277 million for its interest in four data centers and redeployed $55 million to buy out Cyxtera’s leases in Digital Realty’s Frankfurt and Singapore data centers. Digital Realty also exercised its option to purchase a data center outside of London, UK, which is expected to close in the second quarter.

Also previously disclosed, in January, Digital Realty and Blackstone Inc. established the first phase of their $7 billion hyperscale data center development joint venture, which includes campuses in Paris and Northern Virginia. The second phase is scheduled to close later this year, upon obtaining the required approvals.

As announced in early March, Digital Realty and Mitsubishi Corporation established a joint venture to support the development of two build-to-suit data centers in the Dallas metro area. The two data centers commenced construction in the fourth quarter of 2022 and can deliver up to 48 megawatts of IT load. Mitsubishi initially invested approximately $200 million to acquire a 65% equity interest in the venture, while Digital Realty maintains a 35% interest. Each partner will fund its pro rata share of the remaining development costs for the two facilities, which are slated for initial completion and commencement in late 2024.

Additionally, as previously disclosed, during the quarter, Digital Realty closed on the purchase of approximately 19 acres of land in Paris, France for approximately €70 million or $76 million. The parcel of land, which was previously leased to Digital Realty, is currently under development to support up to 77 megawatts of IT load.

During the quarter, Digital Realty closed on the sale of 19 acres of vacant land in Sydney, Australia for approximately AU$96 million or $63 million.

Digital Realty also received approximately $92 million of proceeds during the first quarter, pursuant to an agreement to grant land easements for the use of substations on its Digital Dulles campus.

Subsequent to quarter end, Digital Realty and GI Partners expanded their existing joint venture in Chicago, with the sale to GI Partners of a 75% interest in a stabilized hyperscale data center that is situated on the same campus as two stabilized hyperscale data centers that were previously contributed to a joint venture with GI Partners in July 2023. Digital Realty received approximately $388 million of gross proceeds and will maintain a 25% interest in the joint venture. Based on annualized in‐place cash NOI as of March 31, 2024, adjusted for a customary vacancy allowance, the transaction values the facility at a 6.5% cap rate.

Non-GAAP Financial Measures

This document contains non-GAAP financial measures, including FFO, Core FFO, Adjusted FFO, Net Operating Income (NOI), “Same-Capital” Cash NOI and Adjusted EBITDA. A reconciliation from U.S. GAAP net income available to common stockholders to FFO, a reconciliation from FFO to Core FFO, a reconciliation from Core FFO to Adjusted FFO, reconciliation from NOI to Cash NOI, and definitions of FFO, Core FFO, Adjusted FFO, NOI and “Same-Capital” Cash NOI are included as an attachment to this document. A reconciliation from U.S. GAAP net income available to common stockholders to Adjusted EBITDA, a definition of Adjusted EBITDA and definitions of net debt-to-Adjusted EBITDA, debt-plus-preferred-to-total enterprise value, cash NOI, and fixed charge coverage ratio are included as an attachment to this document.

The Company does not provide a reconciliation for non-GAAP estimates on a forward-looking basis, where it is unable to provide a meaningful or accurate calculation or estimation of reconciling items and the information is not available without unreasonable effort. This is due to the inherent difficulty of forecasting the timing and/or amount of various items that would impact net income attributable to common stockholders per diluted share, which is the most directly comparable forward-looking GAAP financial measure. This includes, for example, external growth factors, such as dispositions, and balance sheet items such as debt issuances, that have not yet occurred, are out of the Company's control and/or cannot be reasonably predicted. For the same reasons, the Company is unable to address the probable significance of the unavailable information. Forward-looking non-GAAP financial measures provided without the most directly comparable GAAP financial measures may vary materially from the corresponding GAAP financial measures.

(2) Certain of Teraco's minority indirect shareholders have the right to put their shares in an upstream parent company of Teraco to Digital Realty in exchange for cash or the equivalent value of shares of Digital Realty common stock, or a combination thereof. US GAAP requires Digital Realty to assume the put right is settled in shares for purposes of calculating diluted EPS. This same approach was utilized to calculate FFO/share. The potential future dilutive impact associated with this put right will be excluded from Core FFO and AFFO until settlement occurs – causing diluted share count to be higher for FFO than for Core FFO and AFFO. When calculating diluted FFO, Teraco related minority interest is added back to the FFO numerator as the denominator assumes all shares have been put back to Digital Realty.

(1) Represents the purchase price or sale price, as applicable before contractual price adjustments, transaction expenses, taxes, and potential currency fluctuations. All prices converted to USD based on FX rate as of March 31,2024.

(2) We calculate the cash capitalization rate on acquisitions, dispositions, and joint venture contributions by dividing anticipated annual net operating income by the purchase/sale/contribution price, including assumed debt and related pre-payment penalties. Net operating income represents rental revenue and tenant reimbursement revenue from in-place leases, less rental property operating and maintenance expenses, property taxes and insurance expenses, and is not a financial measure calculated in accordance with GAAP. We caution you not to place undue reliance on our cash capitalization rates because they are based solely on data made available to us in the diligence process in connection with the relevant acquisitions and are calculated on a non-GAAP basis. Our calculation of the cash capitalization rate on acquisitions may change, based on our experience operating the data centers subsequent to closing of the acquisitions. In addition, the actual cash capitalization rates may differ from our expectations based on numerous other factors, including the results of our final purchase price allocation, difficulties collecting anticipated rental revenues, tenant bankruptcies, property tax reassessments and unanticipated expenses at the data centers that we cannot pass on to tenants.

(3) We estimate the total net rentable square feet available for lease based on a number of factors in addition to contractually leased square feet, including available power, required support space and common area.

(4) Occupancy excludes space under active development and space held for development.

(5) Blackstone acquired an 80% interest, while Digital Realty maintains a 20% interest and will manage the development and day-to-day operations of the JV. Contribution price is shown at 100%.

(6) GI Partners acquired an additional 15% equity interest in two stabilized hyperscale data center buildings in the Chicago metro area, increasing their stake from 65% to 80%, for approximately $68 million. Contribution price is shown at 100%.

(7) Mitsubishi invested approximately $200 million to acquire a 65% interest while Digital Realty maintains a 35% interest in the joint venture for the development of two build-to-suit hyperscale data centers in the Dallas metro area. Each partner will fund its pro rata share of the remaining development costs of the projects. Contribution price is shown at 100%.

Management Statements on Non-GAAP Measures		Financial Supplement
Unaudited		First Quarter 2024

Definitions

Funds From Operations (FFO):

We calculate funds from operations, or FFO, in accordance with the standards established by the National Association of Real Estate Investment Trusts (Nareit) in the Nareit Funds From Operations White Paper - 2018 Restatement. FFO is a non-GAAP financial measure and represents net income (loss) (computed in accordance with GAAP), excluding gain (loss) from the disposition of real estate assets, provision for impairment, real estate related depreciation and amortization (excluding amortization of deferred financing costs), our share of unconsolidated JV real estate related depreciation & amortization, net income attributable to non-controlling interests in operating partnership and, depreciation related to non-controlling interests. Management uses FFO as a supplemental performance measure because, in excluding real estate related depreciation and amortization and gains and losses from property dispositions and after adjustments for unconsolidated partnerships and joint ventures, it provides a performance measure that, when compared year over year, captures trends in occupancy rates, rental rates and operating costs. We also believe that, as a widely recognized measure of the performance of REITs, FFO will be used by investors as a basis to compare our operating performance with that of other REITs. However, because FFO excludes depreciation and amortization and captures neither the changes in the value of our data centers that result from use or market conditions, nor the level of capital expenditures and capitalized leasing commissions necessary to maintain the operating performance of our data centers, all of which have real economic effect and could materially impact our financial condition and results from operations, the utility of FFO as a measure of our performance is limited. Other REITs may not calculate FFO in accordance with the Nareit definition and, accordingly, our FFO may not be comparable to other REITs’ FFO. FFO should be considered only as a supplement to net income computed in accordance with GAAP as a measure of our performance.

Core Funds from Operations (Core FFO):

We present core funds from operations, or Core FFO, as a supplemental operating measure because, in excluding certain items that do not reflect core revenue or expense streams, it provides a performance measure that, when compared year over year, captures trends in our core business operating performance. We calculate Core FFO by adding to or subtracting from FFO (i) other non-core revenue adjustments, (ii) transaction and integration expenses, (iii) loss from early extinguishment of debt, (iv) gain on / issuance costs associated with redeemed preferred stock, (v) severance, equity acceleration and legal expenses, (vi) gain/loss on FX revaluation, and (vii) other non-core expense adjustments. Because certain of these adjustments have a real economic impact on our financial condition and results from operations, the utility of Core FFO as a measure of our performance is limited. Other REITs may calculate Core FFO differently than we do and accordingly, our Core FFO may not be comparable to other REITs’ Core FFO. Core FFO should be considered only as a supplement to net income computed in accordance with GAAP as a measure of our performance.

Adjusted Funds from Operations (AFFO):

We present adjusted funds from operations, or AFFO, as a supplemental operating measure because, when compared year over year, it assesses our ability to fund dividend and distribution requirements from our operating activities. We also believe that, as a widely recognized measure of the operations of REITs, AFFO will be used by investors as a basis to assess our ability to fund dividend payments in comparison to other REITs, including on a per share and unit basis. We calculate AFFO by adding to or subtracting from Core FFO (i) non-real estate depreciation, (ii) amortization of deferred financing costs, (iii) amortization of debt discount/premium, (iv) non-cash stock-based compensation expense, (v) straight-line rental revenue, (vi) straight-line rental expense, (vii) above- and below-market rent amortization, (viii) deferred tax expense / (benefit), (ix) leasing compensation and internal lease commissions, and (x) recurring capital expenditures. Other REITs may calculate AFFO differently than we do and, accordingly, our AFFO may not be comparable to other REITs’ AFFO. AFFO should be considered only as a supplement to net income computed in accordance with GAAP as a measure of our performance.

EBITDA and Adjusted EBITDA:

We believe that earnings before interest, loss from early extinguishment of debt, income taxes, and depreciation and amortization, or EBITDA, and Adjusted EBITDA (as defined below), are useful supplemental performance measures because they allow investors to view our performance without the impact of non-cash depreciation and amortization or the cost of debt and, with respect to Adjusted EBITDA, (i) unconsolidated joint venture real estate related depreciation & amortization, (ii) unconsolidated joint venture interest expense and tax, (iii) severance, equity acceleration and legal expenses, (iv) transaction and integration expenses, (v) gain (loss) on sale / deconsolidation, (vi) provision for impairment, (vii) other non-core adjustments, net, (viii) non-controlling interests, (ix) preferred stock dividends, and (x) issuance costs associated with redeemed preferred stock. Adjusted EBITDA is EBITDA excluding (i) unconsolidated joint venture real estate related depreciation & amortization, (ii) unconsolidated joint venture interest expense and tax, (iii) severance, equity acceleration and legal expenses, (iv) transaction and integration expenses, (v) gain (loss) on sale / deconsolidation, (vi) provision for impairment, (vii) other non-core adjustments, net, (vii) non-controlling interests, (ix) preferred stock dividends, and (x) gain on / issuance costs associated with redeemed preferred stock. In addition, we believe EBITDA and Adjusted EBITDA are frequently used by securities analysts, investors, and other interested parties in the evaluation of REITs. Because EBITDA and Adjusted EBITDA are calculated before recurring cash charges including interest expense and income taxes, exclude capitalized costs, such as leasing commissions, and are not adjusted for capital expenditures or other recurring cash requirements of our business, their utility as a measure of our performance is limited. Other REITs may calculate EBITDA and Adjusted EBITDA differently than we do and, accordingly, our EBITDA and Adjusted EBITDA may not be comparable to other REITs’ EBITDA and Adjusted EBITDA. Accordingly, EBITDA and Adjusted EBITDA should be considered only as supplements to net income computed in accordance with GAAP as a measure of our financial performance.

Net Operating Income (NOI) and Cash NOI:

Net operating income, or NOI, represents rental revenue, tenant reimbursement revenue and interconnection revenue less utilities expense, rental property operating expenses, property taxes and insurance expenses (as reflected in the statement of operations). NOI is commonly used by stockholders, company management and industry analysts as a measurement of operating performance of the company’s rental portfolio. Cash NOI is NOI less straight-line rents and above- and below-market rent amortization. Cash NOI is commonly used by stockholders, company management and industry analysts as a measure of property operating performance on a cash basis. Same-Capital Cash NOI represents buildings owned as of December 31, 2022 of the prior year with less than 5% of total rentable square feet under development and excludes buildings that were undergoing, or were expected to undergo, development activities in 2023-2024, buildings classified as held for sale, and buildings sold or contributed to joint ventures for all periods presented (prior period numbers adjusted to reflect current same-capital pool). However, because NOI and cash NOI exclude depreciation and amortization and capture neither the changes in the value of our data centers that result from use or market conditions, nor the level of capital expenditures and capitalized leasing commissions necessary to maintain the operating performance of our data centers, all of which have real economic effect and could materially impact our results from operations, the utility of NOI and cash NOI as measures of our performance is limited. Other REITs may calculate NOI and cash NOI differently than we do and, accordingly, our NOI and cash NOI may not be comparable to other REITs’ NOI and cash NOI. NOI and cash NOI should be considered only as supplements to net income computed in accordance with GAAP as measures of our performance.

Additional Definitions

Net debt-to-Adjusted EBITDA ratio is calculated as total debt at balance sheet carrying value, plus capital lease obligations, plus Digital Realty’s pro rata share of unconsolidated joint venture debt, less cash and cash equivalents (including Digital Realty’s pro rata share of unconsolidated joint venture cash) divided by the product of Adjusted EBITDA (including Digital Realty’s pro rata share of unconsolidated joint venture EBITDA), multiplied by four.

Debt-plus-preferred-to-total enterprise value is total debt plus preferred stock divided by total debt plus the liquidation value of preferred stock and the market value of outstanding Digital Realty Trust, Inc. common stock and Digital Realty Trust, L.P. units, assuming the redemption of Digital Realty Trust, L.P. units for shares of Digital Realty Trust, Inc. common stock.

Fixed charge coverage ratio is Adjusted EBITDA divided by the sum of GAAP interest expense, capitalized interest and preferred stock dividends. For the quarter ended March 31, 2024, GAAP interest expense was $110 million, capitalized interest was $29 million and preferred stock dividends was $10 million.
