Guidance for 2019 Adjusted EBITDA is a non-IFRS figure intended to adjust for certain items. The definition of Adjusted EBITDA can be found in the “Definitions” section in this slide deck. Interxion does not provide an outlook for an IFRS profitability metric. Consequently, the company is unable to reconcile the outlook for Adjusted EBITDA.

Illustrative ARPU Development ARPU increases over time as IT workloads increase: Customers initially contract for space, connectivity and modest power reservation(1) As workloads increase, larger power reservation fees and cross-connects are required and energy consumption increases Revenue grows from space, cross-connects, power reservation and energy consumption over time As data centres fill with customers: Revenue mix initially tilted toward space As space becomes more fully utilised, revenue growth from power reservation and energy consumption can continue Power reservation is the fee for infrastructure power (cooling, power distribution, etc.). Customer ARPU Development Data Centre Recurring Revenue Development Power Reservation & Energy Consumption Cross-Connects Revenue Develops Over Time Driven by Power Reservation and Energy Consumption Space Installed

IFRS 16 – Lease Accounting Metric Significant Considerations Impact Revenue Certain components of revenue are recognised as lease revenue. Negligible impact on revenue metrics Adjusted EBITDA Properties and other assets leased under operating lease agreements are recognised as right of use assets and lease liabilities, reducing rent expense and increasing interest expense and depreciation charges. 530 bps increase to Adjusted EBITDA margin in 1Q 2019 Leverage Recognising right of use assets and lease liabilities for data centres leased under operating leases increases the level of reported third party debt resulting in an increase in reported gross and net leverage. Impact as at 31 March 2019: Gross leverage (LQA): +0.8x Net leverage (LQA): +1.1x IFRS 16 adopted 1 January 2019 Operating leases and financial leases are now treated the same IFRS 16 does not impact Interxion’s financial covenant reporting on debt or revolving credit facilities More comparable with our U.S. peer group

Adjusted EBITDA: We define Adjusted EBITDA as Operating Income adjusted for depreciation and amortisation, share-based payments, income or expense related to the evaluation and execution of potential mergers or acquisitions and adjustments related to terminated and unused data centre sites. In certain circumstances, we may also adjust for other items that management believes are not representative of our current on-going performance. Examples include: adjustments for the cumulative effect of a change in accounting principle or estimate, impairment losses, litigation gains and losses or windfall gains and losses Adjusted EBITDA excluding the impact of IFRS 16: For comparative purposes with regard to Adjusted EBITDA presented in periods prior to 1 January 2019, the effective date of IFRS 16, we present Adjusted EBITDA excluding the impact of IFRS 16 - Leases. Adjusted diluted earnings per share: Adjusted diluted earnings per share amounts are determined on Adjusted net income Adjusted net income: We define Adjusted net income as net income adjusted to exclude income or expense related to the evaluation and execution of potential mergers or acquisitions, adjustments to provisions which are not reflective of our ongoing performance, and adjustments related to capitalised interest. In certain circumstances, we may also adjust for other items that management believes are not representative of our current on-going performance. Examples include: adjustments for the cumulative effect of a change in accounting principle or estimate, impairment losses, litigation gains and losses or windfall gains and losses ARPU: Monthly recurring revenue per square meter calculated as {reported recurring revenue in the quarter divided by 3} divided by {sum of prior and current quarter end reported revenue generating space divided by 2} Big 4: France, Germany, the Netherlands and the UK CAGR: Compound Annual Growth Rate Capital expenditures including intangible assets: Represent payments to acquire property, plant and equipment and intangible assets as recorded on our consolidated statement of cash flows as "Purchase of property, plant and equipment" and “Purchase of intangible assets”, respectively. Investments in intangible assets include power grid rights and software development Cash generated from operations: Net cash flows from operating activities, excluding interest and fees paid, interest received and income tax paid Cash ROGIC: Cash Return on Gross Invested Capital defined as {LTM (last twelve months) Adjusted EBITDA (excluding IFRS16 adjustments) less cash taxes, less maintenance and other capex} divided by {Average of opening and closing Gross Invested Capital}. Where Gross Invested Capital represents gross PP&E plus gross Intangible assets plus gross Goodwill, less assets under construction, less carrying value of undeveloped land Definitions Constant Currency: Measurements of the given metric that eliminate the effects of foreign currency rate fluctuations. To calculate this information, current and comparative prior period results for entities reporting in currencies other than Euro are converted into Euro using the average exchange rates from the comparative period rather than the actual exchange rates in effect during the respective periods Corporate and Other: Unallocated items mainly comprising general and administrative expenses, assets and liabilities associated with our headquarters operations, provisions for onerous contracts (relating to the discounted amount of future losses expected to be incurred in respect of unused data centre sites over the term of the relevant leases) and revenue and expenses related to those onerous contracts, loans and borrowings and related expenses and income tax assets and liabilities Churn: Contracted Monthly Recurring Revenue which came to an end during the month as a percentage of the total contracted Monthly Recurring Revenue at the beginning of the month. Churn is calculated as a monthly average over the last 12 months Customer Available Power: The current installed electrical customer capacity Equipped Space: The amount of data centre space that, on the relevant date, is equipped and either sold or could be sold, without making any significant additional investments to common infrastructure LTM or Last Twelve Months: Twelve-month period ended 31 March 2019, unless otherwise noted MW: Megawatts Recurring Revenue: Revenue incurred from colocation and associated power charges, office space, amortised set-up fees, cross-connects and certain recurring managed services (but excluding any ad hoc managed services) provided by us directly or through third parties, excluding rents received for the sublease of unused sites Rest of Europe / ROE: Austria, Belgium, Denmark, Ireland, Spain, Sweden, and Switzerland Revenue Generating Space: the amount of Equipped Space that is under contract and billed on the relevant date SQM: Square metres Utilisation Rate: On the relevant date, Revenue Generating Space as a percentage of Equipped Space. Some Equipped Space is not fully utilised due to customers' specific requirements regarding the layout of their equipment. In practice, therefore, Utilisation Rate does not reach 100%
