Forward-looking Statements

This communication contains forward-looking statements that involve risks and uncertainties. There can be no assurance that such statements will prove to be accurate and actual results and future events could differ materially from those anticipated in such forward-looking statements. Factors that could cause actual results and future events to differ materially from Interxion’s expectations include, but are not limited to, the difficulty of reducing operating expenses in the short term, the inability to utilise the capacity of newly planned data centres and data centre expansions, significant competition, the cost and supply of electrical power, data centre industry over-capacity, performance under service level agreements, delays in remediating the material weakness in internal control over financial reporting and/or making disclosure controls and procedure effective, certain other risks detailed herein and other risks described from time to time in Interxion’s filings with the United States Securities and Exchange Commission (the “SEC”).

Interxion does not assume any obligation to update the forward-looking information contained in this report.

Non-IFRS Financial Measures

Included in these materials are certain non-IFRS financial measures, which are measures of our financial performance that are not calculated and presented in accordance with IFRS, within the meaning of applicable SEC rules. These measures are as follows: (i) Adjusted EBITDA; (ii) Recurring revenue; (iii) Revenue on a constant currency basis; (iv) Adjusted net income; (v) Adjusted basic earnings per share; (vi) Adjusted diluted earnings per share and (vii) Cash generated from operations.

Other companies may present Adjusted EBITDA, Recurring revenue, Revenue on a constant currency basis, Adjusted net income, Adjusted basic earnings per share, Adjusted diluted earnings per share and Cash generated from operations differently than we do. Each of these measures are not measures of financial performance under IFRS and should not be considered as an alternative to operating income or as a measure of liquidity or an alternative to Profit for the period attributable to shareholders (“net income”) as indicators of our operating performance or any other measure of performance implemented in accordance with IFRS.

Adjusted EBITDA, Recurring revenue and Revenue on a constant currency basis

We define Adjusted EBITDA as Operating income adjusted for the following items, which may occur in any period, and which management believes are not representative of our operating performance:

• Depreciation and amortisation – property, plant and equipment and intangible assets (except goodwill) are depreciated on a straight-line basis over the estimated useful life. We believe that these costs do not represent our operating performance.
• Share-based payments – represents primarily the fair value at the date of grant of employee equity awards, which is recognised as an expense over the vesting period. In certain cases, the fair value is redetermined for market conditions at each reporting date, until the final date of grant is achieved. We believe that this expense does not represent our operating performance.
• Income or expense related to the evaluation and execution of potential mergers or acquisitions (“M&A”) – under IFRS, gains and losses associated with M&A activity are recognised in the period in which such gains or losses are incurred. We exclude these effects because we believe they are not reflective of our ongoing operating performance.
• Adjustments related to terminated and unused data centre sites – these gains and losses relate to historical leases entered into for certain brownfield sites, with the intention of developing data centres, which were never developed and for which management has no intention of developing into data centres. We believe the impact of gains and losses related to unused data centres are not reflective of our business activities and our ongoing operating performance.

In certain circumstances, we may also adjust for other items that management believes are not representative of our current ongoing 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.

We define Recurring revenue as 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.

We believe Adjusted EBITDA and Recurring revenue provide useful supplemental information to investors regarding our ongoing operational performance. These measures help us and our investors evaluate the ongoing operating performance of the business after removing the impact of our capital structure (primarily interest expense) and our asset base (primarily depreciation and amortisation). Management believes that the presentation of Adjusted EBITDA, when combined with the primary IFRS presentation of net income, provides a more complete analysis of our operating performance. Management also believes the use of Adjusted EBITDA facilitates comparisons between us and other data centre operators (including other data centre operators that are REITs) and other infrastructure-based businesses. Adjusted EBITDA is also a relevant measure used in the financial covenants of our revolving credit facility and our 4.75% Senior Notes due 2025.

A reconciliation from net income to Adjusted EBITDA is provided in the tables attached to this press release. Adjusted EBITDA and other key performance indicators may not be indicative of our historical results of operations, nor are they meant to be predictive of future results.

We present constant currency information for revenue to provide a framework for assessing how our underlying businesses performed excluding the effect of foreign currency rate fluctuations. To present 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 prior period rather than the actual exchange rates in effect during the current period.

We believe that revenue growth is a key indicator of how a company is progressing from period to period and presenting constant currency information for revenue provides useful supplemental information to investors regarding our ongoing operational performance because it helps us and our investors evaluate the ongoing operating performance of the business after removing the impact of acquisitions and currency exchange rates.

Adjusted net income, Adjusted basic earnings per share and Adjusted diluted earnings per share

We define Adjusted net income as net income adjusted for the following items and the related income tax effect, which may occur in any period, and which management believes are not reflective of our operating performance:

• Income or expense related to the evaluation and execution of potential mergers or acquisitions (“M&A”) – under IFRS, gains and losses associated with M&A activity are recognised in the period in which such gains or losses are incurred. We exclude these effects because we believe they are not reflective of our ongoing operating performance.
• Adjustments related to provisions – these adjustments are made for adjustments in provisions that are not reflective of the ongoing operating performance of Interxion. These adjustments may include changes in provisions for onerous lease contracts.
• Adjustments related to capitalised interest – under IFRS, we are required to calculate and capitalise interest allocated to the investment in data centres and exclude it from net income. We believe that reversing the impact of capitalised interest provides information about the impact of the total interest costs and facilitates comparisons with other data centre operators.

In certain circumstances, we may also adjust for items that management believes are not representative of our current ongoing performance. Examples include: adjustments for the cumulative effect of a change in accounting principle or estimate, impairment losses, costs related to refinancing, litigation gains and losses or windfall gains and losses.

Management believe that the exclusion of certain items listed above provides useful supplemental information to net income to aid investors in evaluating the operating performance of our business and comparing our operating performance with other data centre operators and infrastructure companies. We believe the presentation of Adjusted net income, when combined with net income prepared in accordance with IFRS, is beneficial to a complete understanding of our performance. A reconciliation from reported net income to Adjusted net income is provided in the tables attached to this press release.

Adjusted basic earnings per share and Adjusted diluted earnings per share amounts are determined on Adjusted net income.

Cash generated from operations

Cash generated from operations is defined as net cash flows from operating activities, excluding interest and corporate income tax payments and receipts. Management believe that the exclusion of these items provides useful supplemental information to net cash flows from operating activities to aid investors in evaluating the cash generating performance of our business.

Management’s outlook for 2018 included in this press release includes a range for expected Adjusted EBITDA, a non-IFRS financial measure, which excludes items that management believes are not representative of our operating performance. These items include, but are not limited to, depreciation and amortisation, share-based payments, income or expense related to the evaluation and execution of potential mergers or acquisitions, adjustments related to terminated and unused data centre sites, and other significant items that currently cannot be predicted. The exact amount of these items is not currently determinable but may be significant. Accordingly, the company is unable to provide equivalent reconciliations from the corresponding forward-looking IFRS measures to expected Adjusted EBITDA.

1 Recurring revenue is 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.

2 Adjusted net income (or ‘Adjusted earnings’) and Adjusted EBITDA are non-IFRS figures intended to adjust for certain items and are not measures of financial performance under IFRS. Complete definitions can be found in the “Non-IFRS Financial Measures” section in this press release. Reconciliations of net income to Adjusted EBITDA and net income to Adjusted net income can be found in the financial tables later in this press release.

3 Capital expenditures, including intangible assets, represent payments to acquire property, plant, equipment and intangible assets, as recorded in the consolidated statement of cash flows as "Purchase of property, plant and equipment" and "Purchase of intangible assets", respectively.

4 We present constant currency information to provide a framework for assessing how our underlying businesses performed excluding the effect of foreign currency rate fluctuations. For purposes of calculating Revenue on a constant currency basis, 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 prior period rather than the actual exchange rates in effect during the current period. The reconciliation of total revenue growth to total revenue growth on a constant currency basis, is as follows:

Three months ended 30 June 2018   Year-on-year   Sequential   Reported total revenue growth 14.9 % 3.7 % Add back: impact of foreign currency translation 0.9 % 0.1 % Total revenue growth on an organic constant currency basis 15.8 % 3.8 %  

5 We define Cash generated from operations as net cash flows from operating activities, excluding interest and corporate income tax payments and receipts.

6 Totals from the end of 1Q 2018 include 2,300 sqm of equipped space and 1,300 sqm of revenue generating space from Interxion Science Park. 2Q 2017 excludes the impact of Interxion Science Park.
