Additional Information and Where to Find It

On December 6, 2019, we filed a Registration Statement on Form S-4 in connection with the transactions contemplated by the Purchase Agreement, dated as of October 29, 2019, among Digital Realty, InterXion and the other parties thereto, which included a proxy statement/prospectus. This communication is for information purposes only and does not constitute an offer to sell or the solicitation of an offer to buy any securities or a solicitation of any proxy, vote or approval with respect to the proposed transaction or otherwise, nor shall there be any sale of securities in any jurisdiction in which such offer, solicitation or sale would be unlawful prior to registration or qualification under the securities laws of any such jurisdiction. After the registration statement is declared effective by the Securities and Exchange Commission (“SEC”), Digital Realty intends to mail a definitive proxy statement/prospectus to shareholders of Digital Realty and Digital Realty intends to cause its subsidiary to file a Tender Offer Statement on Schedule TO (the “Schedule TO”) with the SEC, and soon thereafter InterXion intends to file a Solicitation/Recommendation Statement on Schedule 14D-9 (the “Schedule 14D-9”) with respect to the tender offer. The tender offer for the outstanding common stock of InterXion referred to in this document has not yet commenced. The solicitation and offer to purchase shares of InterXion’s common stock will only be made pursuant to the Schedule TO and


related offer to purchase. This material is not a substitute for the proxy statement/prospectus, the Schedule TO, the Schedule 14D-9 or the Registration Statement or for any other document that Digital Realty or InterXion may file with the SEC and send to Digital Realty’s or InterXion’s shareholders in connection with the proposed transactions.

BEFORE MAKING ANY VOTING OR INVESTMENT DECISION OR DECISION WITH RESPECT TO THE TENDER OFFER, WE URGE INVESTORS OF DIGITAL REALTY AND INTERXION TO READ THE REGISTRATION STATEMENT, PROXY STATEMENT/PROSPECTUS, SCHEDULE TO (INCLUDING AN OFFER TO PURCHASE, RELATED LETTER OF TRANSMITTAL AND OTHER OFFER DOCUMENTS) AND SCHEDULE 14D-9, AS EACH MAY BE AMENDED OR SUPPLEMENTED FROM TIME TO TIME, AND OTHER RELEVANT DOCUMENTS FILED BY DIGITAL REALTY AND INTERXION WITH THE SEC CAREFULLY WHEN THEY BECOME AVAILABLE BECAUSE THEY WILL CONTAIN IMPORTANT INFORMATION ABOUT DIGITAL REALTY, INTERXION AND THE PROPOSED TRANSACTIONS.

Investors will be able to obtain free copies of the Registration Statement, proxy statement/prospectus, Schedule TO and Schedule 14D-9, as each may be amended from time to time, and other relevant documents filed by Digital Realty and InterXion with the SEC (when they become available) at http://www.sec.gov, the SEC’s website, or free of charge from Digital Realty’s website (http://www.digitalrealty.com) or by contacting Digital Realty’s Investor Relations Department at (415) 848-9311. These documents are also available free of charge from InterXion’s website (http://www.interxion.com) or by contacting InterXion’s Investor Relations Department at (813) 644-9399.

Participants in the Solicitation

Digital Realty, InterXion and their respective directors and certain of their executive officers and employees may be deemed, under SEC rules, to be participants in the solicitation of proxies from Digital Realty’s and InterXion’s shareholders in connection with the proposed transactions. Information regarding the officers and directors of Digital Realty is included in its definitive proxy statement for its 2019 annual meeting filed with the SEC on April 1, 2019. Information regarding the officers and directors of InterXion and their ownership of InterXion ordinary shares is set forth in InterXion’s Annual Report on Form 20-F, which was filed with the SEC on April 30, 2019. Additional information regarding the persons who may be deemed participants and their interests will be set forth in the proxy statement/prospectus and other materials when they are filed with SEC in connection with the proposed transactions. Free copies of these documents may be obtained as described in the paragraphs above.

Note Regarding Forward-Looking Statements

Digital Realty and InterXion caution that statements in this communication that are forward-looking, and provide other than historical information, involve risks, contingencies and uncertainties that may impact actual results of operations of Digital Realty, InterXion and the combined company. These forward-looking statements include, among other things, statements about anticipated satisfaction of closing conditions and completion of the proposed transactions contemplated by the purchase agreement between them. Although we believe that the expectations reflected in those forward-looking statements are reasonable, we can give no assurance that those expectations will prove to have been correct. Those statements are made by using various underlying assumptions and are subject to numerous risks, contingencies and uncertainties, including, among others: the ability of Digital Realty and InterXion to obtain the regulatory and shareholder approvals necessary to complete the anticipated combination, on the anticipated timeline or at all; the risk that a condition to the closing of the anticipated combination may not be satisfied, on the anticipated timeline or at all or that the anticipated combination may fail to close; the outcome of any legal proceedings, regulatory proceedings or enforcement matters that may be instituted relating to the anticipated combination; the costs incurred to consummate the anticipated combination; the possibility that the expected synergies from the anticipated combination will not be realized, or will not be realized within the expected time period; difficulties related to the integration of the two companies; disruption from the anticipated combination making it more difficult


to maintain relationships with customers, employees, regulators or suppliers; the diversion of management time and attention on the anticipated combination; adverse changes in the markets in which Digital Realty and InterXion operate or credit markets; and changes in the terms, scope or timing of contracts, contract cancellations, and other modifications and actions by customers and other business counterparties of Digital Realty and InterXion. If one or more of these risks materialize, or if underlying assumptions prove incorrect, actual results may vary materially from those expected. You should not place undue reliance on forward looking statements. For a more complete discussion of these and other risk factors, please see (i) Digital Realty’s filings with the SEC, including its annual report on Form 10-K for the year ended December 31, 2018 and subsequent quarterly reports on Form 10-Q and (ii) InterXion’s filings with the SEC, including its annual report on Form 20-F for the year ended December 31, 2018 and its subsequent reports on Form 6-K. This communication reflects the views of Digital Realty’s management as of the date hereof. Except to the extent required by applicable law, Digital Realty undertakes no obligation to update or revise any forward-looking statement.

Appendix Management Statements on Non-GAAP Measures The information included in this presentation contains certain non-GAAP financial measures that management believes are helpful in understanding our business, as further described below. Our definition and calculation of non-GAAP financial measures may differ from those of other REITs, and, therefore, may not be comparable. The non-GAAP financial measures should not be considered an alternative to net income or any other GAAP measurement of performance and should not be considered an alternative to cash flows from operating, investing or financing activities as a measure of liquidity. 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, severance, equity acceleration, and legal expenses, transaction and integration expenses, (gain) loss on real estate transactions, equity in earnings adjustment for non-core items, other non-core adjustments, net, noncontrolling interests, preferred stock dividends, including undeclared dividends, and issuance costs associated with redeemed preferred stock. Adjusted EBITDA is EBITDA excluding unconsolidated joint venture real estate related depreciation & amortization, severance, equity acceleration, and legal expenses, transaction and integration expenses, gain on sale / deconsolidation, impairment of investments in real estate, other non-core adjustments, net, non-controlling interests, and preferred stock dividends, including undeclared dividends. 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. 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.
