Investment Activity

During the fourth quarter, Digital Realty signed definitive agreements with Brookfield Infrastructure Partners L.P., Cyxtera Technologies and Digital Core REIT to successfully resolve the relationship with Cyxtera. These agreements were completed in conjunction with Brookfield's announced agreement to acquire Cyxtera, pursuant to its Plan of Reorganization under its Chapter 11 proceedings. As part of the agreements, Brookfield would acquire Digital Realty's interest in four data centers for approximately $275 million, Digital Realty would redeploy $55 million to buy out Cyxtera's leases in three Digital Realty data centers in Singapore and Frankfurt, Brookfield would grant Digital Realty a purchase option to acquire a data center outside of London, UK, Brookfield would assume the leases in three data centers previously leased to Cyxtera, and Brookfield would amend the leases in these three data centers in New Jersey and Los Angeles, accelerating the expiration date to September 2024. Subsequent to year end, Digital Realty closed on the transactions and exercised its purchase option to acquire the data center outside of London, UK, which is expected to close at the end of the first quarter.

As previously disclosed, in mid-November, Digital Realty and Realty Income Corporation established a joint venture to support the development of two build-to-suit data centers in Northern Virginia. Realty Income initially invested approximately $200 million to acquire an 80% equity interest in the venture, while Digital Realty maintains a 20% interest. Each partner will fund its pro rata share of the remaining development costs for the two facilities. The build-to-suit facilities are 100% pre-leased and are expected to generate a 6.9% initial cash lease yield upon lease commencement in mid-2024.

Also previously disclosed, in December, Digital Realty and Blackstone Inc. announced a $7 billion joint venture to develop four hyperscale data center campuses across Frankfurt, Paris and Northern Virginia. The campuses are planned to support the construction of 10 data centers with approximately 500 megawatts of potential IT load capacity. Blackstone will initially invest approximately $700 million to acquire an 80% equity interest in the joint venture, while Digital Realty maintains a 20% interest. Digital Realty will manage the development and day-to-day operations of the joint venture, for which it will receive customary fees. Subsequent to year end, the first phase of the joint venture closed on hyperscale data center campuses in Paris and Northern Virginia, while the second phase is scheduled to close later this year, upon obtaining the required regulatory approvals.

Additionally, Digital Realty completed the sale of an option maintained on a second parcel of land in Sydney, Australia with an area of 21 acres for approximately AU$29 million or $20 million.

Further during the fourth quarter, Digital Realty exercised its option to purchase approximately 19 acres of land (PAR 8 - 11) in Paris, France for approximately EUR70 million or $77 million. The parcel of land, previously leased to Digital Realty, is currently under development to support up to 77 megawatts of IT load. Subsequent to year end, Digital Realty closed on PAR 8 - 11.

In addition, during the fourth quarter, Digital Realty closed on the acquisition of approximately three acres adjacent to its existing campus near Athens, Greece for approximately EUR6 million or $6 million. This land can support the development of an additional data center (ATH5) with up to 15 megawatts of IT load.

Subsequent to year end, GI Partners executed its option to acquire an additional 15% interest in two stabilized hyperscale data center buildings in Chicago, increasing their interest from the 65% interest acquired in the third quarter to 80%. The top-up, completed at the same terms as the initial closing, resulted in approximately $68 million of gross proceeds to Digital Realty.

Balance Sheet

Digital Realty had approximately $17.4 billion of total debt outstanding as of December 31, 2023, comprised of $16.8 billion of unsecured debt and approximately $0.6 billion of secured debt and other. At the end of the fourth quarter of 2023, net debt-to-Adjusted EBITDA was 6.2x, debt-plus-preferred-to-total enterprise value was 29.8% and fixed charge coverage was 3.8x. Pro forma for the completion of the Blackstone development joint ventures announced in December 2023, the completion of asset sales, and the issuance of common stock subsequent to year end, net debt-to-Adjusted EBITDA was 5.8x.

During the quarter, Digital Realty sold 8.7 million shares of its common stock at a weighted average price of $133.21 per share through its ATM program, for net proceeds of approximately $1.1 billion. Subsequent to year end, the company sold 0.6 million shares of its common stock at a weighted average price of $133.43 per share for net proceeds of approximately $84 million.

Subsequent to year end, the company retired $240 million of the $740 million U.S. dollar term loan.

     Note: 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. Please see Non-GAAP Financial Measures in this document for further discussion.

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) Recurring capital expenditures represent non-incremental building improvements required to maintain current revenues, including second-generation
            tenant improvements and external leasing commissions. Recurring capital expenditures do not include acquisition costs contemplated when underwriting
            the purchase of a building, costs which are incurred to bring a building up to Digital Realty's operating standards, or internal leasing commissions.



     (2) For a definition and discussion of AFFO, see the Definitions section. For a reconciliation of net income available to common stockholders to FFO and
            Core FFO, see above.



     (3) For all periods presented, we have excluded the effect of dilutive series J, series K and series L preferred stock, as applicable, that may be converted
            into common stock upon the occurrence of specified change in control transactions as described in the articles supplementary governing the series J,
            series K and series L preferred stock, as applicable, which we consider highly improbable. See above for calculations of FFO and for calculations of
            weighted average common stock and units outstanding.

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, or Nareit, in the Nareit Funds From Operations White Paper - 2018 Restatement. FFO represents net income (loss) (computed in accordance with GAAP), excluding (i) gains (or losses) from real estate transactions, (ii) provision for impairment, real estate related depreciation and amortization (excluding amortization of deferred financing costs), (iii) unconsolidated JV real estate related depreciation & amortization, (iv) non-controlling interests in operating partnership, (v) depreciation related to non-controlling interests and (vi) after adjustments for unconsolidated partnerships and joint ventures. 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, 2021 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 2022-2023, 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 December 31, 2023, GAAP interest expense was $114 million, capitalized interest was $33 million and preferred stock dividends was $10 million.
