Introduction

Presentation of Financial Information

Unless otherwise indicated, the financial information in this annual report has been prepared in accordance with International Financial
Reporting Standards, or IFRS, as issued by the International Accounting Standards Board. The significant IFRS accounting policies applied to our financial information in this annual report have been applied consistently.

Financial Information

The financial
information included in Financial Statements is covered by the auditors report included therein. The audit was carried out in accordance with standards issued by the Public Company Accounting Oversight Board (United States).

EBITDA and Adjusted EBITDA

In this
annual report we refer to our EBITDA and Adjusted EBITDA. We define EBITDA as operating profit plus depreciation, amortization and impairment of assets. We define Adjusted EBITDA as EBITDA adjusted to exclude share-based payments, M&A
transaction costs1, increase/decrease in provision for onerous lease contracts, M&A transaction break fee income, and income from sub-leases of unused data center sites. Adjusted EBITDA margin
is defined as Adjusted EBITDA as a percentage of revenue. For a reconciliation of EBITDA and Adjusted EBITDA to Operating profit/(loss) and Profit for the year attributable to shareholders, see Operating and Financial Review and
ProspectsEBITDA and Adjusted EBITDA. EBITDA, 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.

Additional Key Performance Indicators

In
addition to EBITDA and Adjusted EBITDA, our management also uses the following key performance indicators as measures to evaluate our performance:



| |  |  | Equipped Space: the amount of data center space that, on the relevant date, is equipped and either sold or could be sold, without making any significant additional investments to common infrastructure. Equipped Space at
a particular data center may decrease if either (a) the power requirements of customers at a data center change so that all or a portion of the remaining space can no longer be sold as the space does not have enough power capacity and/or common
infrastructure to support it without further investment or (b) if the design and layout of a data center changes to meet among others, fire regulations or customer requirements, and necessitates the introduction of common space (such as
corridors) which cannot be sold to individual customers;
| | - |  | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Revenue Generating Space is defined as the amount of Equipped Space that is under contract and billed on the relevant date;
| | - |  | ---------------------------------------------------------------------------------------------------------------------------



| |  |  | Utilization Rate: on the relevant date, Revenue Generating Space as a percentage of Equipped Space. Some Equipped Space is not fully utilized due to customers specific requirements regarding the layout of their
equipment. In practice, therefore, Utilization Rate does not reach 100%;
| | - |  | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Recurring Revenue Percentage: Recurring Revenue during the relevant period as a percentage of total revenue in the same period. Recurring Revenue comprises revenue that is incurred from colocation and associated power
charges, office space, amortized set-up fees and certain recurring managed services (but excluding any ad hoc managed services) provided by us directly or through third parties. Rents received for the sublease of unused sites are excluded. Monthly
Recurring Revenue is the contracted Recurring Revenue over a full month excluding energy usage revenues, amortized set-up fees and the sub-leasing of office space; and

|1 | M&A transaction costs are costs associated with the evaluation, diligence and conclusion or termination of merger or acquisition activity. In the year ended December 31, 2015, M&A transaction costs included
10.7 million related to the abandoned merger with TelecityGroup, and 1.1 million related to other activity including the evaluation of potential asset acquisitions.

| |  |  | Average Monthly Churn: the average of the Churn Percentage in each month of the relevant period. Churn Percentage in a month is the 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.
| | - |  | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

EBITDA, Adjusted EBITDA,
Adjusted EBITDA margin, Recurring Revenue and Average Monthly Churn are all non-GAAP measures. Together with the other key performance indicators listed above, they serve as additional indicators of our operating performance and are not required by,
or presented in accordance with, IFRS. They are not intended as a replacement for, or alternatives to, measures such as cash flows from operating activities and operating profit as defined and required under IFRS. We believe that EBITDA, Adjusted
EBITDA, Adjusted EBITDA margin and our other key performance indicators are measures commonly used by analysts, investors and peers in our industry. We have, therefore, disclosed this information to permit a more complete analysis of our operating
performance. EBITDA, Adjusted EBITDA, Adjusted EBITDA margin and our other key performance indicators, as we calculate them, may not be comparable to similarly titled measures reported by other companies. For a reconciliation of EBITDA and Adjusted
EBITDA to operating profit/(loss), see Operating and Financial Review and ProspectsEBITDA and Adjusted EBITDA. EBITDA, Adjusted EBITDA, Adjusted EBITDA margin and our other key performance indicators listed above may not be
indicative of our historical results of operations, nor are they meant to be predictive of future results.

MARKET, ECONOMIC AND INDUSTRY DATA

Information regarding markets, market size, market share, market position, growth rates and other industry data pertaining to our business
contained in this annual report consists of estimates based on data and reports compiled by professional organizations and analysts, on data from other external sources, and on our knowledge of our sales and markets. In many cases, there is no
readily available external information (whether from trade associations, government bodies or other organizations) to validate market-related analyses and estimates, requiring us to rely on internally developed estimates. While we have compiled,
extracted and reproduced market or other industry data from external sources which we believe to be reliable, including third parties or industry or general publications, we have not independently verified that data. Similarly, our internal
estimates have not been verified by any independent sources.

Forward-Looking Statements

This annual report on Form 20-F contains forward-looking statements within the meaning of Section 27A of the Securities Act of 1933, as
amended, and Section 21E of the Securities Exchange Act of 1934, as amended, with respect to all statements other than statements of historical fact regarding our business, financial condition, results of operations and certain of our plans,
objectives, assumptions, projections, expectations or beliefs with respect to these items and statements regarding other future events or prospects. These statements include, without limitation, those concerning: our strategy and our ability to
achieve it; expectations regarding sales, profitability and growth; plans for the construction of new data centers; our possible or assumed future results of operations; research and development, capital expenditure and investment plans; adequacy of
capital; and financing plans. The words aim, may, will, expect, anticipate, believe, future, continue, help, estimate,
plan, schedule, intend, should, shall or the negative or other variations thereof as well as other statements regarding matters that are not historical fact, are or may constitute
forward-looking statements.

In addition, this annual report includes forward-looking statements relating to our potential exposure to
various types of market risks, such as foreign exchange rate risk, interest rate risks and other risks related to financial assets and liabilities. We have based these forward-looking statements on our managements current view with respect to
future events and financial performance. These views reflect the best judgment of our management but involve a number of risks and uncertainties which could cause actual results to differ materially from those predicted in our forward-looking
statements and from past results, performance or achievements. Although we believe that the estimates reflected in the forward-looking statements are reasonable, those estimates may prove to be incorrect. By their nature, forward-looking statements
involve risk and uncertainty because they relate to events and depend on circumstances that will occur in the future. There are a number of factors that could cause actual results and developments to differ materially from these expressed or implied
by these forward-looking statements. These factors include, among other things:



| |  |  | operating expenses cannot be easily reduced in the short term;
| | - |  | --------------------------------------------------------------



| |  |  | inability to utilize the capacity of newly planned data centers and data center expansions;
| | - |  | -------------------------------------------------------------------------------------------



| |  |  | significant competition;
| | - |  | ------------------------



| |  |  | cost and supply of electrical power;
| | - |  | ------------------------------------



| |  |  | data center industry over-capacity; and
| | - |  | ---------------------------------------



| |  |  | performance under service level agreements.
| | - |  | -------------------------------------------

These risks and others described under Risk
Factors are not exhaustive. Other sections of this annual report describe additional factors that could adversely affect our business, financial condition or results of operations. We urge you to read the sections of this annual report
entitled Item 3 Key InformationRisk Factors, Item 4 Information on the Company and Item 5 Operating and Financial Review and Prospects for a more complete discussion of the factors that could affect our
future performance and the industry in which we operate. Additionally, new risk factors can emerge from time to time, and it is not possible for us to predict all such risk factors, nor can we assess the impact of all such risk factors to differ
materially from those contained in any forward-looking statements. Given these risks and uncertainties, you should not place undue reliance on forward-looking statements as a prediction of actual results.

All forward-looking statements included in this annual report are based on information available to us on the date of this annual report. We
undertake no obligation to update publicly or revise any forward-looking statement, whether as a result of new information, future events or otherwise, except as may be required by applicable law. All subsequent written and oral forward-looking
statements attributable to us or persons acting on our behalf are expressly qualified in their entirety by the cautionary statements contained throughout this annual report.

Risk Factors

In addition to the other information contained in this annual report on Form 20-F, you should carefully consider the following risk
factors. If any of the possible events described below occurs, our business, financial condition, results of operations or prospects could be adversely affected. The risks and uncertainties below are those known to us and that we currently believe
may materially affect us.

Risks Related to our Business

We cannot easily reduce our operating expenses in the short term, which could have a material adverse effect on our business in the event
of a slowdown in demand for our services or a decrease in revenue for any reason.

Our operating expenses primarily consist of
personnel, power and property costs. Personnel and property costs cannot be easily reduced in the short term. Therefore, we are unlikely to be able to reduce significantly our expenses in response to a slowdown in demand for our services or any
decrease in revenue. The terms of our leases with landlords for facilities that serve as data centers are typically for a minimum period of 10 to 15 years (excluding our extension options) and do not provide us with an early termination right, while
our colocation contracts with customers are initially typically for only three to five years. As of December 31, 2015, 55% of our Monthly Recurring Revenue was generated by contracts with terms of one year or less remaining. Our personnel costs
are fixed due to our contracts with our employees having set notice periods and local law limitations in relation to the termination of employment contracts. In respect of our power costs, there is a minimum level of power required to keep our data
centers running irrespective of the number of customers using them so our power costs may exceed the amount of revenue derived from power. We could have higher than expected levels of unused capacity in our data centers if, among other things:



| |  |  | our existing customers contracts are not renewed and those customers are not replaced by new customers;
| | - |  | -------------------------------------------------------------------------------------------------------



| |  |  | internet and telecommunications equipment becomes smaller and more compact in the future;
| | - |  | -----------------------------------------------------------------------------------------



| |  |  | there is an unexpected slowdown in demand for our services; or
| | - |  | --------------------------------------------------------------



| |  |  | we are unable to terminate or amend our leases when we have underutilized space at a data center.
| | - |  | -------------------------------------------------------------------------------------------------

If we have higher than expected levels of unused space at a data center at any given time, we may be required to operate a data center at a
loss for a period of time. If we have higher than expected levels of unused capacity in our data centers and we are unable to reduce our expenses accordingly, our business, financial condition and results of operations would be materially adversely
affected.

Our inability to utilize the capacity of newly planned data centers and data center expansions in line with our business
plan would have a material adverse effect on our business, financial condition and results of operations.

Historically, we have
made significant investments in our property, plant and equipment and intangible assets in order to expand our data center footprint and total Equipped Space as we have grown our business. In the year ended December 31, 2015 we invested
192.6 million in property, plant and equipment (186.1 million) and intangible assets (6.5 million). In the year ended December 31, 2014 we invested 216.3 million in property, plant and equipment (213.0 million) and
intangible assets (3.3 million). Investments in property, plant and equipment includes expansion, upgrade, maintenance and general administrative IT equipment. Investments in intangible assets include power grid rights and software
development.

We expect to continue to invest as we expand our data center footprint and increase our Equipped Space based on demand in
our target markets. Our total annual investment in property, plant and equipment includes maintenance and replacement capital expenditures. Although in any one year the amount of maintenance and replacement capital expenditures may vary, we expect
that such expenses will be between 4% and 6% of total revenue in the long term.

We currently hold title to the AMS3, AMS6, BRU1, CPH2,
FRA8, FRA10, MRS1, PAR3, PAR5 and VIE properties. We completed the acquisition of the VIE properties and terminated the VIE financial lease in January 2015. In June 2015 we finalized the development of the building that will house the FRA10 data
center. This building is located on freehold land owned by us.

We exercised certain purchase options and agreed to purchase the PAR7
freehold land, on which we own the PAR7 data center, and the AMS7 freehold land and properties. The PAR7 and AMS7 properties are currently reported as financial leases, and they will be reported as such until the acquisitions are completed.

##### Table of Contents

We also lease space for data centers and typically begin construction before entering into
contractual agreements with customers to utilize our data centers under construction. In some cases, we enter into lease agreements for data centers or begin expansions at our existing data centers without any pre-existing customer commitments to
use the additional space that will be created. If we open a new data center or complete an expansion at an existing data center, we will be required to pay substantial up-front and ongoing costs associated with that data center, including leasehold
improvements, basic overhead costs and rental payments, regardless of whether or not we have any agreements with customers to utilize those data centers.

As a result of our expansion plans, we will incur capital expenditures, and as a result, an increase in other operating expenses, which will
negatively impact our cash flow, and depreciation that together will negatively impact our profitability unless and until these new and expanded data centers generate enough revenue to exceed their operating costs and related capital expenditures.
There can be no guarantee that we will be able to sustain or increase our profitability if our planned expansion is not successful or if there is not sufficient customer demand in the future to realize expected returns on these investments. Any such
development would have a material adverse effect on our business, financial condition and results of operations.

If we are unable
to expand our existing data centers or locate and secure suitable sites for additional data centers on commercially acceptable terms our ability to grow our business may be limited.

Our ability to meet the growing needs of our existing customers and to attract new customers depends on our ability to add capacity by
expanding existing data centers or by locating and securing suitable sites for additional data centers that meet our specifications, such as proximity to numerous network service providers, access to a significant supply of electrical power and the
ability to sustain heavy floor loading. We have reached high utilization levels at some of our data centers and therefore any increase in these locations would need to be accomplished through the lease of additional property that satisfies our
requirements. Property meeting our specifications may be scarce in our target markets. If we are unable to identify and enter into leases on commercially acceptable terms on a timely basis for any reason including due to competition from other
companies seeking similar sites who may have greater financial resources than us, or are unable to expand our space in our current data centers, our rate of growth may be substantially impaired.

Our capital expenditures, together with ongoing operating expenses and obligations to service our debt, will be a drain on our cash flow and
may decrease our cash balances. The capital markets in the recent past have been and may again become limited for external financing opportunities. Additional debt or equity financing, especially in the current credit-constrained climate, may not be
available when needed or, if available, may not be available on satisfactory terms. Our inability to obtain needed debt and/or equity financing or to generate sufficient cash from operations may require us to prioritize projects or curtail capital
expenditures which could adversely affect our results of operations.

Failure to renew or maintain real estate leases for our
existing data centers on commercially acceptable terms, or at all, could harm our business.

For the leased properties on which our
data centers are located, we generally enter into leases for initial minimum periods of 10 to 15 years (excluding renewal options). Including renewal options, the lease properties are generally secured for terms of 20 to 25 years. The majority of
our leases are subject to an annual inflation-linked increase in rent and, on renewal (or earlier in some cases), the rent we pay may be reset to the current market rate. There is, therefore, a risk that there will be significant rent increases when
the rent is reviewed.

Our leases in France, Ireland and the United Kingdom do not contain contractual options to renew or extend those
leases, and we have exhausted or may in the future exhaust such options in other leases. With respect to our operating leases in France, certain landlords may terminate our operating leases following the expiration of the original lease period
(being 12 years from the commencement date), and the other leases in France may be terminated by the landlords at the end of each three year period upon giving six months prior notice in the event the landlord wishes to carry out construction works
to the building. The non-renewal of leases for our existing data center locations, or the renewal of such leases on less favorable terms, is a potentially significant risk to our ongoing operations. We would incur significant costs if we were forced
to vacate one of our data centers due to the high costs of relocating our own and our customers equipment, installing the necessary infrastructure in a new data center and, as required by most of our leases, reinstating the vacated data center
to its original state. In addition, if we were forced to vacate a data center, we could lose customers that chose our services based on location. If we fail to renew any of our leases, or the renewal of any of our leases is on less favorable terms
and we fail to increase revenues sufficiently to offset the higher rental costs, this could have a material adverse effect on our business, financial condition and results of operations.

##### Table of Contents

Our leases may obligate us to make payments beyond our use of the property.

Our leases generally do not give us the right to terminate without penalty. Accordingly, we may incur costs under leases of data center space
that is not or no longer is Revenue Generating Space. Some of our leases do not give us the right to sublet, and even if we have that right we may not be able to sublet the space on favorable terms or at all. We have incurred moderate costs in
relation to such onerous lease contracts in recent years.

We may experience unforeseen delays and expenses when fitting out and
upgrading data centers, and the costs could be greater than anticipated.

As we attempt to grow our business, substantial
management effort and financial resources are employed by us in fitting out new, and upgrading existing, data centers. In addition, we periodically upgrade and replace certain equipment at our data centers. We may experience unforeseen delays and
expenses in connection with a particular client project or data center build-out. In addition, unexpected technological changes could affect customer requirements and we may not have built such requirements into our data centers and may not have
budgeted for the financial resources necessary to build out or redesign the space to meet such new requirements. Furthermore, the redesign of existing space is difficult to implement in practice as it normally requires moving existing customers.
Although we have budgeted for expected build-out and equipment expenses, additional expenses in the event of unforeseen delays, cost overruns, unanticipated expenses, regulatory changes, unexpected technological changes and increases in the price of
equipment may negatively affect our business, financial condition and results of operations.

No assurance can be given that we will
complete the build-out of new data centers or expansions of existing data centers within the proposed timeframe and cost parameters or at all. Any such failure could have a material adverse effect on our business, financial condition and results of
operations.

We may incur non-cash impairment charges to our assets, in particular to our property, plant and equipment, which could
result in a reduction to our earnings.

In accordance with IFRS, we periodically monitor the remaining net book values of our
investments, intangible assets and our property, plant and equipment (based on cash generating units) for indications of a material change in balance sheet carrying value, particularly indications of any impairments. It is possible that one or more
data centers could begin to under-perform relative to our expectations due to changes in customer requirements or regulatory changes affecting the efficient operation of the data center which may then also result in a non-cash impairment charge. In
addition, capitalized data center development costs may also be subject to impairment due to events or changes in circumstances, such as changing market conditions or any changes in key assumptions, which result in delaying or terminating a data
center development project giving rise to a non-cash impairment charge.

We face significant competition and we may not be able to
compete successfully against current and future competitors.

Our market is highly competitive. Most companies operate their own
data centers and in many cases continue to invest in data center capacity, although there is a trend towards outsourcing. We compete against other carrier and cloud-neutral colocation data center service providers, such as Equinix Telecity, formerly
Equinix and TelecityGroup, which merged in January 2016, and Telehouse. We also compete with other types of data centers, including carrier-operated colocation, wholesale and IT outsourcers and managed services provider data centers. The cost,
operational risk and inconvenience involved in relocating a customers networking and computing equipment to another data center are significant and have the effect of protecting a competitors data center from significant levels of
customer churn.

Further, the growth of the European data center market has encouraged new, larger companies to consider entering the
market, in particular those from the United States who are active in this sector. This growth and other factors have also led to increasing alliances and consolidation. For example, as a result of the Equinix and TelecityGroup merger, we may be
subject to increased competition and face a shift in the competitive landscape. In addition, many of these companies may have significantly greater financial, marketing and other resources than we do. Some of our competitors may be willing to, and
due to greater financial resources, may be better able to adopt aggressive pricing policies, including the provision of discounted data center services as an encouragement for customers to utilize their other services. Certain of our competitors may
also provide our target customers with additional benefits, including bundled communications services, and may do so in a manner that is more attractive to potential customers than obtaining space in our data centers.

In addition, corporations that have already invested substantial resources in in-house data center operations may be reluctant to outsource
these services to a third party, or may choose to acquire space within a wholesale providers data center, which would allow them to manage the equipment themselves. If existing customers were to conclude that they could provide the same
service in-house at a lower cost, with greater reliability, with increased security or for other reasons, they might move such services in-house and we would lose customers and business.

We may also see increased competition for data center space and customers from wholesale data
center providers, such as large real estate companies. Rather than leasing available space to large single tenants, real estate companies, including certain of our landlords, may decide to convert the space instead to smaller square meter units
designed for multitenant colocation use. In addition to the risk of losing customers to wholesale data center providers, this could also reduce the amount of space available to us for expansion in the future. As a result of such competition, we
could suffer from downward pricing pressure and the loss of customers (and potential customers), which would have a material adverse effect on our business, financial condition and results of operations.

Our services may have a long sales cycle that may materially adversely affect our business, financial condition and results of
operations.

A customers decision to take space in one of our data centers typically involves a significant commitment of
resources by us and by potential customers, who often require internal approvals. In addition, some customers will be reluctant to commit to locating in our data centers until they are confident that the data center has adequate available carrier
connections and network density. As a result, we may have a long sales cycle lasting anywhere from three months for smaller customers to periods in excess of one year for some of our larger customers. Furthermore, we may expend significant time and
resources in pursuing a particular sale or customer that does not result in revenue.

The slowdown in global economies and their delayed
recovery may further impact this long sales cycle by making it extremely difficult for customers to accurately forecast and plan future business activities. This could cause customers to slow spending, or delay decision-making, on our services,
which would delay and lengthen our sales cycle.

Delays due to the length of our sales cycle may have a material adverse effect on our
business, financial condition and results of operations.

Our business is dependent on the adequate supply of electrical power and
could be harmed by prolonged electrical power outages or increases in the cost of power.

The operation of each of our data centers
requires an extremely large amount of power and we are among the largest power consumers in certain cities in which we operate data centers. We cannot be certain that there will be adequate power in all of the locations in which we operate, or
intend to open additional data centers. We attempt to limit exposure to system downtime caused by power outages by using back-up generators and uninterrupted power supply systems; however, we may not be able to limit our exposure entirely even with
these protections in place. We also cannot guarantee that the generators will always provide sufficient power or restore power in time to avoid loss of or damage to our customers and our equipment. Any loss of services or damage to equipment
resulting from a temporary loss of or reduction in power at any of our data centers could harm our customers, reduce customers confidence in our services, impair our ability to attract new customers and retain existing customers, and result in
us incurring financial obligations to our customers as they might be eligible for service credits pursuant to their service level agreements with us. Our customers may also seek damages from us.

In addition, we are susceptible to fluctuations in power costs in all of the locations in which we operate. Clients have two options with
respect to power usage. They can either (i) pay for power usage in plugs in advance (typically included in the total cabinet price), which are contractually defined amounts of power per month, for which the customer must pay in
full, regardless of how much power is actually used; or (ii) pay for their actual power usage in arrears on a metered basis. While we are contractually able to recover power cost increases from our customers, some portion of the increased costs
may not be recovered or recovered in a delayed fashion based on commercial reasons and as a result, may have a negative impact on our results of operations.

Although we have not experienced any power outages that have had a material impact on our financial condition in the past, power outages or
increases in the cost of power to us could have a material adverse effect on our business, financial condition and results of operations.

A general lack of electrical power resources sufficient to meet our customers demands may impair our ability to utilize fully the
available space at our existing data centers or our plans to open new data centers.

In each of our markets, we rely on third
parties to provide a sufficient amount of power for current and future customers. Power and cooling requirements are generally growing on a per customer basis. Some of our customers are increasing and may continue to increase their use of
high-density electrical power equipment, such as blade servers, which can significantly increase the demand for power per customer and cooling requirements for our data centers. Future demand for electrical power and cooling may exceed the designed
electrical power and cooling infrastructure in our data centers. As the electrical power infrastructure is typically one of the most important limiting factors in our data centers, our ability to utilize available space fully may be limited. This,
as well as any inability to secure sufficient power resources from third-party providers, could have a negative impact on the effective available capacity of a given data center and limit our ability to grow our business.

##### Table of Contents

The ability to increase the power capacity or power infrastructure of a data center, should we
decide to, is dependent on several factors including, but not limited to, the local utilitys ability and willingness to provide additional power, the length of time required to provide that power and/or whether it is feasible to upgrade the
electrical infrastructure and cooling systems of a data center to deliver additional power to customers.

The availability of sufficient
power may also pose a risk to the successful development of future data centers. In cities where we intend to open new data centers, we may face delays in obtaining sufficient power to operate our data centers. Our ability to secure adequate power
sources will depend on several factors, including whether the local power supply is at or close to its limit, whether new connections for our data center would require the local power company to install a new substation or feeder and whether new
connections for our data center would increase the overall risks of blackouts or power outages in a given geographic area.

If we are
unable to utilize fully the physical space available within our data centers or successfully develop additional data centers or expand existing data centers due to restrictions on available electrical power or cooling, we may be unable to accept new
customers or increase the services provided to existing customers, which may have a material adverse effect on our business, results of operations and financial condition.

A significant percentage of our Monthly Recurring Revenue is generated by contracts with terms of one year or less remaining. If those
contracts are not renewed, or if their pricing terms are negotiated downwards, our business, financial condition and results of operations would be materially adversely affected.

The majority of our initial customer contracts are entered into on a fixed term basis for periods from three to five years, which, unless
terminated in advance, are automatically renewed for subsequent one-year periods. Please see Item 4 Information on the CompanyCustomer Contracts. As of December 31, 2015, 55% of our Monthly Recurring Revenue was generated
by contracts with terms of one year or less remaining. Consequently, a large part of our customer base could either terminate their contracts with us at relatively short notice, or seek to re-negotiate the pricing of such contracts downwards, which,
if either were to occur, would have a material adverse effect on our business, financial condition and results of operations.

Our
inability to use all or part of our net deferred tax assets could cause us to pay taxes at an earlier date and in greater amounts than expected.

As of December 31, 2015, we had 13.1 million of recognized net deferred tax assets and 0.2 million of unrecognized net
deferred tax assets. We cannot assure you that we will generate sufficient profit in the relevant jurisdictions to utilize these deferred tax assets fully or that the tax loss availability will not expire before we have been able to fully utilize
them. In addition, applicable law could change in one or more jurisdictions in which we have deferred tax assets, rendering such assets unusable. Either such event would cause us to pay taxes in greater amounts than would otherwise occur, which may
have a material adverse effect on our results of operations.

Our operating results have fluctuated in the past and may fluctuate in
the future, which may make it difficult to evaluate our business and prospects.

Our operating results have fluctuated in the past
and may continue to fluctuate in the future, due to a variety of factors, which include:



| |  |  | demand for our services;
| | - |  | ------------------------



| |  |  | competition from other data center operators;
| | - |  | ---------------------------------------------



| |  |  | the cost and availability of power;
| | - |  | -----------------------------------



| |  |  | the introduction of new services by us and/or our competitors;
| | - |  | --------------------------------------------------------------



| |  |  | data center expansion by us and/or our competitors;
| | - |  | ---------------------------------------------------

| |  |  | changes in our pricing policies and those of our competitors;
| | - |  | -------------------------------------------------------------



| |  |  | a change in our customer retention rates;
| | - |  | -----------------------------------------



| |  |  | economic conditions affecting the Internet, telecommunications and e-commerce industries; and
| | - |  | ---------------------------------------------------------------------------------------------



| |  |  | changes in general economic conditions.
| | - |  | ---------------------------------------

Any of the foregoing factors, or other factors
discussed elsewhere in this annual report, could have a material adverse effect on our business, results of operations and financial condition. Although we have experienced growth in revenues during the past three financial years, this growth rate
is not necessarily indicative of future operating results. In addition, a relatively large portion of our expenses cannot be reduced in the short-term, particularly personnel and property costs and part of our power costs, which means that our
results of operations are particularly sensitive to fluctuations in revenues. As such, comparisons to prior reporting periods should not be relied upon as indications of our future performance. In addition, our operating results in one or more
future periods may fail to meet the expectations of securities analysts or investors. If this happens, the market price of our ordinary shares may decline significantly.

We are dependent on third-party suppliers for equipment, technology and other services.

We contract with third parties for the supply of equipment (including generators, UPS systems and cabinet equipment) on which we are dependent
to operate our business. Poor performance by, or any inability of, our suppliers to provide necessary equipment, products, services and maintenance could have a negative effect on our reputation and harm our business.

We depend on the ongoing service of our personnel and senior management team and may not be able to attract, train and retain a
sufficient number of qualified personnel to maintain and grow our business.

Our success depends upon our ability to attract,
retain and motivate highly-skilled employees, including the data center personnel who are integral to the establishment and running of our data centers, as well as sales and marketing personnel who play a large role in attracting and retaining
customers. Due to several factors, including the rapid growth of the Internet, there is aggressive competition for experienced data center employees. We compete intensely with other companies to recruit and hire from this limited pool. In addition,
the training of new employees requires a large amount of our time and resources. If we cannot attract, train and retain qualified personnel, we may be unable to expand our business in line with our strategy, compete for new customers or retain
existing customers, which could cause our business, financial condition and results of operations to suffer.

Our future performance also
depends to a significant degree upon the continued contributions of our senior management team. The loss of any member of our senior management team could significantly harm us. To the extent that the services of members of our senior management
team would be unavailable to us for any reason, we would be required to hire other personnel to manage and operate our Company. There can be no assurance that we would be able to locate or employ such personnel on acceptable terms or on a timely
basis.

Our failure to maintain competitive compensation packages, including equity incentives, may be disruptive to our business. If one
or more of our key personnel resigns from our Company to join or form a competitor, the loss of such personnel and any resulting loss of existing or potential customers to any such competitor could harm our business, financial condition and results
of operations. In addition, we may be unable to prevent the unauthorized disclosure or use of our technical knowledge, practices or procedures by departed personnel.

Disruptions to our physical infrastructure could lead to significant costs, reduce our revenues and harm our business reputation and
financial results.

Our business depends on providing customers with highly reliable and secure services. A number of factors may
disrupt our ability to provide services to our customers, including:



| |  |  | human error;
| | - |  | ------------



| |  |  | power loss;
| | - |  | -----------



| |  |  | physical or electronic security breaches;
| | - |  | -----------------------------------------



| |  |  | terrorist acts;
| | - |  | ---------------



| |  |  | interruptions to the fiber network;
| | - |  | -----------------------------------



| |  |  | hardware and software defects;
| | - |  | ------------------------------

| |  |  | fire, earthquake, flood and other natural disasters;
| | - |  | ----------------------------------------------------



| |  |  | improper maintenance by our landlords; and
| | - |  | ------------------------------------------



| |  |  | sabotage and vandalism.
| | - |  | -----------------------

The occurrence of any of the foregoing could have a material adverse
effect on our business, results of operations and financial condition. Disruptions at one or more of our data centers, whether or not within our control, could result in service interruptions or significant equipment damage, leading to significant
costs and revenue reductions. Please see Risks Related to our IndustryTerrorist activity throughout the world and military action to counter terrorism could adversely impact our business.

Our insurance may not be adequate to cover all losses.

The insurance we maintain covers material damage to property, business interruption and third-party liability. This insurance contains
limitations on the total coverage for damage due to catastrophic events, such as flooding or terrorism. In addition, there is an overall cap on our general insurance coverage per data center in any one year. There is, therefore, a risk that if one
or more data centers were damaged, the total amount of the loss would not be recoverable by us.

Also, our insurance policies include
customary exclusions, deductibles and other conditions that could limit our ability to recover losses. In addition, some of our policies are subject to limitations involving co-payments and policy limits that may not be sufficient to cover losses.
If we experience a loss that is uninsured or that exceeds policy limits, or if customers consider that there is a significant risk that such an event will occur, this may negatively affect our reputation, business, financial condition and results of
operations.

Our failure to meet the performance standards under our service level agreements may subject us to liability to our
customers, which could have a material adverse effect on our reputation, business, financial condition or results of operations.

We have service level agreements with substantially all of our customers in which we provide various guarantees regarding our level of service.
Our inability to provide services consistent with these guarantees may lead to large losses for our customers, who consequently may be entitled to service credits for their accounts or to terminate their relationship with us. We have issued service
credits to customers in the past due to our failure to meet service level commitments and we may do so in the future. We cannot be sure that our customers will accept these service credits as compensation in the future. Our failure or inability to
meet a customers expectations or any deficiency in the services we provide to customers could result in a claim against us for substantial damages. Provisions contained in our agreements with customers attempting to limit damages, including
provisions to limit liability for damages, may not be enforceable in all instances or may otherwise fail to protect us for liability damages.

We could be subject to costs, as well as claims, litigation or other potential liability, in connection with risks associated with the
security of our data centers and our Information technology systems. We may also be subject to information technology systems failures, network disruptions and breaches of data security, which could have an adverse effect on our reputation and
material adverse impact on our business.

One of our key service offerings is our high level of physical premises security. Many of
our customers entrust their key strategic IT services and applications to us due, in part, to the level of security we offer. If anyone is able to breach our security, they could physically damage our and our customers equipment and/or
misappropriate either our proprietary information or the information of our customers or cause interruptions or malfunctions in our operations.

There can be no assurance that the security of any of our data centers will not be breached or the equipment and information of our customers
put at risk. Any security breach could have a serious effect on our reputation and could prevent new customers from choosing our services and lead to customers terminating their contracts early and seeking to recover losses suffered, which could
have a material adverse effect on our business, financial condition and results of operations. We may incur significant additional costs to protect against physical premises security breaches or to alleviate problems caused by such breaches.

In addition, we can provide no assurance that our IT system is fully protected against third-party intrusions, viruses, hacker attacks,
information or data theft or other similar threats. The risk of a security breach or disruption, particularly through cyber-attack or cyber intrusion, including by computer hackers, foreign governments and cyber terrorists, has risen as the number,
intensity and sophistication of attempted attacks and intrusions from around the world have increased. For example, in December 2015, we became aware that we suffered a breach in our IT security. This resulted in a temporary and localized compromise
of the credentials to our customer relationship management system (CRM) which allowed unauthorized access to some customer and prospective customer contact details. No financial, personal or other sensitive customer data was accessed, or
is stored within this system. This incident only affected our CRM system and did not impact or involve any of the data centers or services that we provide. Upon learning of this incident, we collaborated with our CRM supplier and have worked closely
with our security team to ensure that all CRM information is secure. Any third-party intrusions, viruses, hacker attacks, information or data theft or similar threats against us and our IT systems may have a material adversely affect on our
business, financial condition and results of operations.

We face risks relating to foreign currency exchange rate fluctuations.

Our reporting currency for purposes of our financial statements is the euro. We also, however, earn revenues and incur operating costs in
non-euro denominated currencies, such as British pounds, Swiss francs, Danish kroner, Swedish kronor and US dollars. We recognize foreign currency gains or losses arising from our operations in the period incurred. As a result, currency fluctuations
between the euro and the non-euro currencies in which we do business will cause us to incur foreign currency translation gains and losses. We cannot predict the effects of exchange rate fluctuations upon our future operating results because of the
number of currencies involved, the variability of currency exposure and the potential volatility of currency exchange rates. We do not currently engage in foreign exchange hedging transactions to manage the risk of our foreign currency exposure.

The slowdown in global economies and their delayed recovery may have an impact on our business and financial condition in ways that
we cannot currently predict.

The European debt crisis and slowdown and delayed recovery in the global financial markets could
continue to have an adverse effect on our business and our financial condition. If the market conditions continue to remain weak or uncertain, some of our customers may have difficulty paying us and we may experience increased churn in our customer
base. Our sales cycle could also lengthen as customers slow spending, or delay decision-making, on our services, which could adversely affect our revenue growth. Finally, we could also experience pricing pressure as a result of economic conditions
if our competitors lower prices and attempt to lure away our customers.

Additionally, our ability to access the capital markets may be
severely restricted at a time when we would like, or need, to do so, which could have an impact on our ability to pursue additional expansion opportunities and maintain our desired level of revenue growth in the future.

Acquisitions, business combinations and other transactions present many risks, and we may not realize the financial or strategic goals
that were contemplated at the time of any transaction and such transactions may alter our financial or strategic goals.

We have
evaluated, and expect to continue to evaluate, potential strategic combinations and acquisitions and other transactions. We may enter into transactions like these at any time, or discussions concerning such transactions, which may include
combinations with other companies or businesses, acquisitions of us by third parties, including potential strategic and financial acquirers and acquisitions by us of businesses, products, services or technologies that we believe to be complementary.
These potential transactions expose us to several potential risks, including:



| |  |  | the possible disruption of our ongoing business and diversion of managements attention by acquisition, transition and integration activities and/or entering into discussions that do not result in a transaction;
| | - |  | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | our potential inability to successfully pursue or realize some or all of the anticipated revenue opportunities associated with an acquisition or investment;
| | - |  | ------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | the possibility that we may not be able to successfully integrate acquired businesses, or businesses in which we invest, or achieve anticipated operating efficiencies or cost savings;
| | - |  | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | the possibility that announced acquisitions or business combinations may not be completed, due to failure to satisfy the conditions to closing or for other reasons;
| | - |  | --------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | the dilution of our existing stockholders as a result of any such transaction that involves the issuance of stock;
| | - |  | ------------------------------------------------------------------------------------------------------------------



| |  |  | the possibility of customer dissatisfaction if we are unable to achieve levels of quality and stability on par with past practices or with respect to any business combination with a new party;
| | - |  | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

We may pay for future acquisitions by using our existing cash resources (which may limit other potential uses of our cash), incurring
additional debt (which may increase our interest expense, leverage and debt service requirements) and/or issuing shares (which may dilute our existing stockholders and have a negative effect on our earnings per share). The occurrence of any of these
risks could have a material adverse effect on our business, results of operations, financial condition or cash flows.

We focus on
the development of communities of interest within customer segments and the attraction of magnetic customers. Our failure to attract, grow and retain these communities of interest could harm our business and operating results.

Our ability to maximize revenue growth depends on our ability to develop and grow communities of interest within our target customer segments
such as network providers, cloud and managed service providers, financial services, enterprises and digital media and distribution. Within each community, there are certain customers, which we consider to be magnetic customers as we believe they
make it attractive to other customers to be in our data centers. Our ability to attract magnetic customers to our data centers will depend on a variety of factors, including the presence of multiple carriers, the mix of our offerings, the overall
mix of customers, the presence of other magnetic customers, the data centers operating reliability and security and our ability to effectively market our offerings. We may not be able to attract magnetic customers and thus may be unsuccessful
in the development of our communities of interest. This may hinder the development, growth and retention of customer communities of interest and adversely affect our business, financial condition and results of operations.

Consolidation may have a negative impact on our business model.

If customers combine businesses, they may require less colocation space, which could lead to churn in our customer base. Competitors in some of
our markets may also consolidate, which can make it more difficult for us to compete. Consolidation of our customers and/or our competitors may present a risk to our business model and have a negative impact on our revenues.

Our operations are highly dependent on the proper functioning of our information technology systems. We are in the process of upgrading
our information technology systems. The failure or unavailability of such systems during or after the upgrade process could result in the loss of existing or potential customers and harm our reputation, business and operating results.

We rely heavily on our information technology and back office systems to conduct our business, including for purposes of providing customer fee
quotes and maintaining accurate customer service and billings records. Difficulties with our systems may interrupt our ability to accept and deliver customer orders and impact our overall financial operations, including our accounts payable,
accounts receivables, general ledger, close processes, internal financial controls, and our ability to otherwise run and track our business. We may need to expend significant attention, time and resources to correct problems or find alternative
sources for performing these functions. As a result of any significant investments in ongoing upgrades or any future upgrades or modifications, we may be unable to devote adequate financial and other resources to remedy any such delay or technical
difficulty in an efficient manner.

Any disruption to our information technology and back office systems, whether caused by upgrade
projects or otherwise, may adversely affect our business and operating results.

In December 2015, we became aware that we suffered a
breach in our IT security. This resulted in a temporary and localized compromise of the credentials to our CRM system, which allowed unauthorized access to some customer and prospective customer contact details. No financial, personal or other
sensitive customer data was accessed, or is stored within this system. This incident only affected our CRM system and did not impact or involve any of the data centers or services that we provide. Upon learning of this incident, we collaborated with
our CRM supplier and have worked closely with our security team to ensure that all CRM information is secure.

Substantial
indebtedness could adversely affect our financial condition and our ability to operate our business, and we may not be able to generate sufficient cash flows to meet our debt service obligations.

We have a significant amount of debt and may incur additional debt to support our growth. As of December 31, 2015, our total indebtedness
was approximately 555.8 million, our stockholders equity was 507.4 million and our cash and cash equivalents totaled 58.6 million. Our substantial amount of debt could have important consequences. For example, it
could:



| |  |  | make it more difficult for us to satisfy our debt obligations;
| | - |  | --------------------------------------------------------------



| |  |  | restrict us from making strategic acquisitions;
| | - |  | -----------------------------------------------



| |  |  | limit our flexibility in planning for, or reacting to, changes in our business and future business opportunities, thereby placing us at a competitive disadvantage if our competitors are not as highly leveraged;
| | - |  | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | increase our vulnerability to general adverse economic and industry conditions; or
| | - |  | ----------------------------------------------------------------------------------



| |  |  | require us to dedicate a substantial portion of our cash flow from operations to make interest and principal payments on our debt, reducing the availability of our cash flow to fund future capital expenditures, working
capital, execution of our expansion strategy and other general corporate requirements;
| | - |  | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | limit our ability to borrow additional funds, even when necessary to maintain adequate liquidity, which would also limit our ability to further expand our business; and
| | - |  | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | make us more vulnerable to increases in interest rates because of the variable interest rates on some of our borrowings to the extent we have not entirely hedged such variable rate debt.
| | - |  | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

The occurrence of any of the foregoing factors could have a material adverse effect on our business, results of operations and financial
condition.

We require a significant amount of cash to service our debt, which may limit available cash to fund working capital and
capital expenditures. Our ability to generate sufficient cash depends on many factors beyond our control.

Our ability to make
payments on and to refinance our debt, and to fund working capital and capital expenditures, will depend on our future operating performance and ability to generate sufficient cash. This depends, to some extent, on general economic, financial,
competitive, market, legislative, regulatory and other factors, many of which are beyond our control, as well as the other factors discussed in these Risk Factors.

We cannot assure you that our business will generate sufficient cash flows from operations or that future debt and equity financing will be
available to us in an amount sufficient to enable us to pay our debts when due, including our outstanding 475.0 million 6.00% Senior Secured Notes (the Senior Secured Notes), or to fund our other liquidity needs. See Item 5
Operating and Financial Review and Prospects.

##### Table of Contents

If our future cash flows from operations and other capital resources (including borrowings under
our 100.0 million revolving facility (the Revolving Facility)) are insufficient to pay our obligations as they mature or to fund our liquidity needs, we may be forced to:



| |  |  | reduce or delay our business activities and capital expenditures;
| | - |  | -----------------------------------------------------------------



| |  |  | sell assets;
| | - |  | ------------



| |  |  | obtain additional debt or equity capital; or
| | - |  | --------------------------------------------



| |  |  | restructure or refinance all or a portion of our debt, including the Senior Secured Notes, on or before maturity.
| | - |  | -----------------------------------------------------------------------------------------------------------------

We cannot assure you that we would be able to accomplish any of these alternatives on a timely basis or on satisfactory terms, if at all. In
addition, the terms or our debt, including the Revolving Facility and the Senior Secured Notes, will limit, and any future debt may limit, our ability to pursue any of these alternatives.

We may need to refinance our outstanding debt

We may need to refinance a portion of our outstanding debt as it matures, such as mortgages with quarterly repayment schedules and the Senior
Secured Notes. Furthermore, if prevailing interest rates or other factors at the time of refinancing result in higher interest rates upon refinancing, then the interest expense relating to that refinanced indebtedness would increase. These risks
could materially adversely affect our financial condition, cash flows and results of operations.

If we increase our indebtedness by
borrowing under the Revolving Facility or incur other new indebtedness, the risks described above would increase.

We are subject to
significant restrictive debt covenants, which limit our operating flexibility.

Our Revolving Facility and the Indenture (as
defined below) governing the Senior Secured Notes contain covenants which impose significant restrictions on the way we and our subsidiaries operate, including but not limited to, restrictions on the ability to:



| |  |  | create certain liens;
| | - |  | ---------------------



| |  |  | incur debt and/or guarantees;
| | - |  | -----------------------------



| |  |  | enter into transactions other than on arms-length basis;
| | - |  | ---------------------------------------------------------



| |  |  | pay dividends or make certain distributions or payments;
| | - |  | --------------------------------------------------------



| |  |  | engage, in relation to the Company, in any business activity or own assets or incur liabilities not authorized by the agreement governing the Revolving Facility (the Revolving Facility Agreement);
| | - |  | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | sell certain kinds of assets;
| | - |  | -----------------------------



| |  |  | impair any security interest on the assets serving as collateral for the Senior Secured Notes;
| | - |  | ----------------------------------------------------------------------------------------------



| |  |  | enter into any sale and leaseback transactions;
| | - |  | -----------------------------------------------



| |  |  | make certain investments or other types of restricted payments;
| | - |  | ---------------------------------------------------------------



| |  |  | substantially change the nature of the Companys or the Groups business;
| | - |  | -------------------------------------------------------------------------



| |  |  | designate unrestricted subsidiaries; and
| | - |  | ----------------------------------------



| |  |  | effect mergers, consolidations or sale of assets.
| | - |  | -------------------------------------------------

These covenants could limit our ability to
finance our future operations and capital needs and our ability to pursue acquisitions and other business activities that may be in our interest.

##### Table of Contents

Our Revolving Facility also requires us to maintain a specified financial ratio. The restrictive
covenants are subject to customary exceptions including, in relation to the incurrence of additional debt, a consolidated fixed charge ratio (calculated as a ratio of adjusted EBITDA to consolidated interest expense) to exceed 2.00 to 1.00 on a pro
forma basis for the four full fiscal quarters (taken as one period) for which financial statements are available immediately preceding the incurrence of such debt and, if such debt is senior debt, a consolidated senior leverage ratio (calculated as
a ratio of outstanding senior debt of the Company and its restricted subsidiaries (on a consolidated basis) to pro forma adjusted EBITDA) to be less than 4.00 to 1.00 on a pro forma basis for the four full fiscal quarters (taken as one period) for
which financial statements are available immediately preceding the incurrence of such debt. The Revolving Facility Agreement also includes a leverage ratio financial covenant (tested on a quarterly basis) requiring total net debt (calculated as a
ratio to pro forma EBITDA) not to exceed a leverage ratio of 4.00 to 1.00. In addition, the Company must ensure, under the Revolving Facility Agreement, that the guarantors represent a certain percentage of Adjusted EBITDA of the Group as a whole
and a certain percentage of the consolidated net assets of the Group as a whole. Our ability to meet these covenants may be affected by events beyond our control and, as a result, we cannot assure you that we will be able to meet the covenants. In
the event of a default under our Revolving Facility, the lenders could terminate their commitments and declare all amounts owed to them to be due and payable. Borrowings under other debt instruments that contain cross acceleration or cross default
provisions, including the Senior Secured Notes, may as a result also be accelerated and become due and payable. We may be unable to pay these debts in such circumstances or to the extent we pay such debts, we may not have sufficient cash to fund our
working capital expenditure needs.

Risks Related to our Industry

The European data center industry has suffered from over-capacity in the past, and a substantial increase in the supply of new data
center capacity and/or a general decrease in demand for data center services could have an adverse impact on industry pricing and profit margins.

The European data center industry has previously suffered from overcapacity. For example, certain Internet-based customers have previously
contracted to use more space than necessary to meet their needs and in the periods following adverse market conditions, the number of Internet-related business failures increased significantly, resulting in high levels of customer churn due to the
termination or non-renewal of contracts.

A substantial increase in the supply of new data center capacity in the European data center
market and/or a general decrease in demand, or in the rate of increase in demand, for data center services could have an adverse impact on industry pricing and profit margins. If there is insufficient customer demand for data center services, our
business, financial condition and operating results would be adversely affected.

If we do not keep pace with technological changes,
evolving industry standards and customer requirements, our competitive position will suffer.

The Internet and telecommunications
industries are characterized by rapidly changing technology, evolving industry standards and changing customer needs. Accordingly, our future success will depend, in part, on our ability to meet the challenge of these changes. Among the most
important challenges that we may face are the need to: continue to develop our strategic and technical expertise, influence and respond to emerging industry standards and other technological changes, enhance our current services and develop new
services that meet changing customer needs.

All of these challenges must be met in a timely and cost-effective manner. Some of our
competitors may have greater financial resources, which would allow them to react better or more quickly to changes than we may be able to. We may not effectively meet these challenges as rapidly as our competitors or at all and our failure to do so
could harm our business.

Terrorist activity throughout the world and military action to counter terrorism could adversely impact
our business.

Due to the high volume of important data that passes through data centers, there is a real risk that terrorists
seeking to damage financial and technological infrastructure view data centers generally, and those in concentrated areas specifically, as potential targets. These factors may increase our costs due to the need to provide enhanced security, which
would have a material adverse effect on our business, financial condition and results of operations if we are unable to pass such costs on to our customers. These circumstances may also adversely affect the ability of companies, including us, to
raise capital. We may not have adequate property and liability insurance to cover terrorist attacks.

In addition, we depend heavily on
the physical infrastructure (particularly as it relates to power) that exists in the markets in which we operate. Any damage to such infrastructure, particularly in the major European markets such as Amsterdam, Frankfurt, London and Paris, where we
derive a substantial amount of our revenue and which are likely to be more prone to terrorist activities, may materially and adversely affect our business.

Our carrier neutral business model depends on the presence of numerous telecommunications
carrier networks in our data centers.

The presence of diverse telecommunications carriers fiber networks in our data centers
is critical to our ability to retain and attract new customers. We are not a telecommunications carrier and as such we rely on third parties to provide our non-carrier customers with carrier services. We cannot assure you that the carriers operating
within our data centers will not cease to do so. For example, as a result of strategic decisions or consolidations, some carriers may decide to downsize or terminate connectivity within our data centers, which could have an adverse effect on our
business, financial condition and results of operations.

We may be subject to reputational damage and legal action in connection
with the information disseminated by our customers.

We may face potential direct and indirect liability for claims of defamation,
negligence, copyright, patent or trademark infringement and other claims, as well as reputational damage, based on the nature and content of the materials disseminated from our data centers, including on the grounds of allegations of the illegality
of certain activities carried out by customers through their equipment located in our data centers. For example, lawsuits may be brought against us claiming that content distributed by our customers may be regulated or banned. Our general liability
insurance may not cover any such claim or may not be adequate to protect us against all liability that may be imposed. In addition, on a limited number of occasions in the past, businesses, organizations and individuals have sent unsolicited
commercial emails (spam), which may be viewed as offensive by recipients, from servers hosted at our data centers to a number of people, typically to advertise products or services. We have in the past received, and may in the future
receive, letters from recipients of information transmitted by our customers objecting to spam. Although our contracts with our customers prohibit them from spamming, there can be no assurance that customers will not engage in this practice, which
could subject us to claims for damages, damage our reputation and have a material adverse effect on our business.

Risks Related to Regulation

Laws and government regulations governing Internet-related services, related communication services and information technology and
electronic commerce, across the European countries in which we operate, continue to evolve and, depending on the evolution of such regulations, may adversely affect our business.

Laws and governmental regulations governing Internet-related services, related communications services and information technology and
electronic commerce continue to evolve. This is true across the various European countries in which we operate. In particular, the laws regarding privacy and those regarding gambling and other activities that certain countries deem illegal are
continuing to evolve.

Changes in laws or regulations (or the interpretation of such laws or regulations) or national or EU policy
affecting our activities and/or those of our customers and competitors, including regulation of prices and interconnection arrangements, regulation of access arrangements to types of infrastructure, regulation of privacy requirements through the
protection of personal data and regulation of activity considered illegal through rules affecting data center and managed service providers could materially adversely affect our results by decreasing revenue, increasing costs or impairing our
ability to offer services.

We and the industry in which we operate are subject to environmental and health and safety laws and
regulations and may be subject to more stringent efficiency, environmental and health and safety laws and regulations in the future, including with respect to energy consumption and greenhouse gas emissions.

We are subject to various environmental and health and safety laws and regulations, including those relating to the generation, storage,
handling and disposal of hazardous substances and technological equipment, the maintenance of warehouse facilities and the generation and use of electricity. Certain of these laws and regulations are capable of imposing liability for the entire cost
of the investigation and remediation of contaminated sites or buildings containing hazardous materials such as asbestos, without regard to fault or the lawfulness of the activity causing the contamination, on current and former owners and occupiers
of real property and persons who have disposed of or released hazardous substances at any location. Compliance with these laws and regulations could impose substantial ongoing compliance costs and operating restrictions on us.

Hazardous substances or regulated materials of which we are not aware may be present at data centers leased and operated by us. If any such
contaminants are discovered at our data centers, we may be responsible under applicable laws, regulations or leases for any required removal or clean-up or other action at substantial cost.

Our facilities contain tanks and other containers for the storage of diesel fuel and significant
quantities of lead acid batteries to provide back-up power. We cannot guarantee that our environmental compliance program will be able to prevent leaks or spills in these or other technical installations.

In addition, due to our high levels of energy consumption, we may incur substantial costs purchasing allowances under the CRC Energy
Efficiency Scheme and/or in connection with upgrading our data centers to improve the energy efficiency of our operations. This could have an adverse effect on our business, financial condition and results of operations.

Non-compliance with, or liabilities under, existing or future environmental or health and safety laws and regulations, including failure to
hold requisite permits, or the adoption of more stringent requirements in the future, could result in fines, penalties, third-party claims and other costs that could have a material adverse effect on us.

Our data centers may also be adversely affected by any future application of additional regulation relating to energy usage, for example,
seeking to reduce the power consumption of companies and fees or levies related thereto.

Changes in Dutch or foreign tax laws and
regulations, or interpretations thereof may adversely affect our financial position.

We are a Dutch company with European
subsidiaries and are subject to income tax in The Netherlands and foreign income tax in the countries we conduct operations, including The Netherlands, France, Germany and the UK. Significant judgment is required in determining our worldwide tax
liabilities and obligations. Although we believe that we have adequately assessed and accounted for our potential tax liabilities, and that our tax estimates including our transfer pricing estimates are reasonable, there can be no certainty that
additional taxes will not be due upon an audit of our tax returns or as a result of changes to applicable tax laws and interpretations thereof. In addition, several of the governments in which we conduct operations, including The Netherlands,
France, Germany and the UK, are actively considering changes to their respective taxation regimes, which may impact the recognition and taxation of worldwide income. The nature and timing of any amendments to tax laws of the jurisdictions in which
we operate and the impact on our future tax liabilities cannot be predicted with any certainty, however any such amendments or changes could materially and adversely impact our results of operations and financial position including cash flows. In
the years ended December 31, 2013 and 2012, we were adversely impacted by a one-time crisis wage tax in The Netherlands. This tax was introduced as a one-time crisis wage tax, however, we were subject to this tax again in the year ended
December 31, 2013. In the years ended December 31, 2014 and 2015, this crisis wage tax was no longer collected.

Laws and government
regulations governing the licenses or permits we need across the European countries in which we operate may change, which can adversely affect our business .

We operate data centers and other facilities in 11 countries and as a result of our international operations, we are subject to risks related
to the differing legal, political, social and regulatory requirements and economic conditions of many jurisdictions. General economic, political, or social conditions in the countries in which we operate could have an adverse effect on our revenues
from operations in those countries. In addition, we may be unable to obtain, renew or retain licenses or permits for our operations, data centers and other facilities for legal, environmental or regulatory reasons. For example, on December 13, 2013,
we were awarded a permit by the Seine-St-Denis authorities to operate our PAR7 data center. On October 15, 2015, a French administrative court ruled that local authorities failed to perform a sufficiently extensive study of the potential noise
impact that operating the PAR7 data center could have on local residents and consequently the French administrative court annulled the permit we received on December 13, 2013. We have appealed this ruling. The Seine-St-Denis authorities have
requested that we re-apply for a new permit and on March 2, 2016 we submitted an application for a new permit with the relevant administrative authorities. We have worked with the Seine-St-Denis authorities and we obtained formal approval to
continue to operate the PAR7 data center during the application process, which we expect to conclude by the end of 2016. Our inability to obtain, renew or retain licenses or permits for our operations, data centers and other facilities may adversely
affect our business, results of operations, financial conditions or cash flows.

Risks Related to Our Ordinary Shares

The market price for our ordinary shares may continue to be volatile.

##### Table of Contents

From January 1, 2015 to December 31, 2015, the closing sale price of our common stock
on the New York Stock Exchange (the NYSE) ranged from $26.11 to $32.50 per share. The market price for our shares is likely to be highly volatile and subject to wide fluctuations in response to factors including, but not limited to, the
following:



| |  |  | announcements of new products and services by us or our competitors;
| | - |  | --------------------------------------------------------------------



| |  |  | technological breakthroughs in the data center, networking or computing industries;
| | - |  | -----------------------------------------------------------------------------------



| |  |  | news regarding any gain or loss of customers by us;
| | - |  | ---------------------------------------------------



| |  |  | news regarding recruitment or loss of key personnel by us or our competitors;
| | - |  | -----------------------------------------------------------------------------



| |  |  | announcements of competitive developments, acquisitions or strategic alliances in our industry;
| | - |  | -----------------------------------------------------------------------------------------------



| |  |  | changes in the general condition of the global economy and financial markets;
| | - |  | -----------------------------------------------------------------------------



| |  |  | general market conditions or other developments affecting us or our industry;
| | - |  | -----------------------------------------------------------------------------



| |  |  | the operating and stock price performance of other companies, other industries and other events or factors beyond our control;
| | - |  | ------------------------------------------------------------------------------------------------------------------------------



| |  |  | cost and availability of power and cooling capacity;
| | - |  | ----------------------------------------------------



| |  |  | cost and availability of additional space inventory either through lease or acquisition in our target markets;
| | - |  | --------------------------------------------------------------------------------------------------------------



| |  |  | regulatory developments in our target markets affecting us, our customers or our competitors;
| | - |  | ---------------------------------------------------------------------------------------------



| |  |  | changes in demand for interconnection and colocation products and services in general or at our facilities in particular;
| | - |  | -------------------------------------------------------------------------------------------------------------------------



| |  |  | actual or anticipated fluctuations in our quarterly results of operations;
| | - |  | --------------------------------------------------------------------------



| |  |  | changes in financial projections or estimates about our financial or operational performance by securities research analysts;
| | - |  | -----------------------------------------------------------------------------------------------------------------------------



| |  |  | changes in the economic performance or market valuations of other data center companies;
| | - |  | ----------------------------------------------------------------------------------------



| |  |  | release or expiry of lock-up or other transfer restrictions on our outstanding ordinary shares; and
| | - |  | ---------------------------------------------------------------------------------------------------



| |  |  | sales or perceived sales of additional ordinary shares.
| | - |  | -------------------------------------------------------

In addition, the securities market
has from time to time experienced significant price and volume fluctuations that are not related to the operating performance of particular companies. These market fluctuations may also have a material adverse effect on the market price of our
ordinary shares.

A substantial portion of our total outstanding ordinary shares may be sold into the market at any time. Such
future sales or issuances, or perceived future sales or issuances, could adversely affect the price of our shares.

If our existing
shareholders sell, or are perceived as intending to sell, substantial amounts of our ordinary shares, including those issued upon the exercise of our outstanding share options, the market price of our ordinary shares could be adversely impacted.
Such sales, or perceived potential sales, by our existing shareholders might make it more difficult for us to issue new equity or equity-related securities in the future at a time and price we deem appropriate. The ordinary shares offered in our
initial public offering were eligible for immediate resale in the public market without restrictions. Shares previously held by our existing shareholders may also be sold in the public market in the future if registered under the Securities Act of
1933, as amended (the Securities Act), or if such shares qualify for an exemption from registration, including by reason of Rules 144 or 701 under the Securities Act. Additionally, we intend to register all of our ordinary shares that we
may issue under our employee stock ownership plans. Once we register those shares, they can be freely sold in the public market upon issuance, unless pursuant to their terms these stock awards have transfer restrictions attached to them.

You may not be able to exercise pre-emptive rights.

Prior to January 28, 2016, and pursuant to our articles of association, our Board of Directors (as defined herein), for a period of 5 years
that lasted until January 28, 2016, had the power to (a) limit or exclude pre-emptive rights in respect of any issue and/or (b) grant rights to subscribe for ordinary shares. As of June 30, 2015, our Board of Directors, for a period of 18 months,
from June 30, 2015 onwards, has the power to grant rights to subscribe for up to 4,352,281 ordinary shares for the purpose of our employee incentive schemes and to the extent any such shares are granted, they will not include pre-emptive rights for
the benefit of shareholders. As a result, we may issue additional shares while excluding any pre-emptive rights. If we issue additional shares without pre-emptive rights, your ownership interests in our Company would be diluted and this in turn
could have a material adverse effect on the price of our shares.

We may need additional capital and may sell additional ordinary shares or other equity
securities or incur indebtedness, which could result in additional dilution to our shareholders or increase our debt service obligations.

We believe that our current cash and anticipated cash flow from operations will be sufficient to meet our anticipated cash needs for the
foreseeable future. We may, however, require additional cash resources due to changed business conditions or other future developments, including any investments or acquisitions we may decide to pursue. If these resources are insufficient to satisfy
our cash requirements, we may seek to sell additional equity or debt securities or utilize our existing or obtain a new credit facility. The sale of additional equity securities could result in additional dilution to our shareholders. The incurrence
of indebtedness would limit our ability to pay dividends or require us to seek consents for the payment of dividends, increase our vulnerability to general adverse economic and industry conditions, limit our ability to pursue our business
strategies, require us to dedicate a substantial portion of our cash flow from operations to service our debt, thereby reducing the availability of our cash flow to fund capital expenditure, working capital requirements and other general corporate
needs, and limit our flexibility in planning for, or reacting to, changes in our business and our industry. We cannot assure you that financing will be available in amounts or on terms acceptable to us, if at all.

We have never paid, do not currently intend to pay and may not be able to pay any dividends on our ordinary shares.

We have never declared or paid any dividends on our ordinary shares and currently do not plan to declare dividends on our ordinary shares in
the foreseeable future. If we were to choose to declare dividends in the future, the payment of cash dividends on our shares is restricted under the terms of the agreements governing our indebtedness and the Implementation Agreement. In addition,
because we are a holding company, our ability to pay cash dividends on our ordinary shares may be limited by restrictions on our ability to obtain sufficient funds through dividends from subsidiaries, including restrictions under the terms of the
agreements governing our and our subsidiaries indebtedness. In that regard, our wholly-owned subsidiaries are limited in their ability to pay dividends or otherwise make distributions to us. Under Dutch law, we may only pay dividends out of
profits as shown in our adopted statutory annual accounts. We will only be able to declare and pay dividends to the extent our equity exceeds the sum of the paid and called up portion of our ordinary share capital and the reserves that must be
maintained in accordance with provisions of Dutch law and our articles of association. Our Board of Directors will have the discretion to determine to what extent profits shall be retained by way of a reserve. Appropriation and distribution of
dividends will be subject to the approval of our general meeting of shareholders. Our Board of Directors, in determining to what extent profits shall be retained by way of a reserve, will consider our ability to declare and pay dividends in light of
our future operations and earnings, capital expenditure requirements, general financial conditions, legal and contractual restrictions and other factors that it may deem relevant.

Your rights and responsibilities as a shareholder will be governed by Dutch law and will differ in some respects from the rights and
responsibilities of shareholders under U.S. law, and your shareholder rights under Dutch law may not be as clearly established as shareholder rights are established under the laws of some U.S. jurisdictions.

Our corporate affairs are governed by our articles of association and by the laws governing companies incorporated in The Netherlands. The
rights of our shareholders and the responsibilities of members of our Board of Directors under Dutch law may not be as clearly established as under the laws of some U.S. jurisdictions. In the performance of its duties, our Board of Directors will be
required by Dutch law to consider the interests of our Company, our shareholders, our employees and other stakeholders in all cases with reasonableness and fairness. It is possible that some of these parties will have interests that are different
from, or in addition to, your interests as a shareholder. We anticipate that all of our shareholder meetings will take place in The Netherlands.

In addition, the rights of holders of ordinary shares and many of the rights of shareholders as they relate to, for example, the exercise of
shareholder rights, are governed by Dutch law and our articles of association and differ from the rights of shareholders under U.S. law. For example, Dutch law does not grant appraisal rights to a companys shareholders who wish to challenge
the consideration to be paid upon a merger or consolidation of the company. See Item 10 Additional InformationGeneral.

The provisions of Dutch corporate law and our articles of association have the effect of concentrating control over certain corporate
decisions and transactions in the hands of our Board of Directors. As a result, holders of our shares may have more difficulty in protecting their interests in the face of actions by members of our Board of Directors than if we were incorporated in
the United States. See Item 10 Additional InformationGeneral.

##### Table of Contents

We are a foreign private issuer and, as a result, and as permitted by the listing
requirements of the NYSE, we may rely on certain home country governance practices rather than the corporate governance requirements of the NYSE.

Many of the corporate governance rules of the NYSE do not apply to us as a foreign private issuer; however, Rule 303A.11 requires
foreign private issuers to describe significant differences between their corporate governance standards and the corporate governance standards applicable to U.S. companies listed on the NYSE. While we believe that our corporate governance practices
are similar in many respects to those of U.S. NYSE-listed companies and provide investors with protections that are comparable in many respects to those established by the NYSE rules, there have historically been certain key differences which are
described below.

Our nominating committee and compensation committee did not historically meet the NYSE independence standard, as
one member of each respective committee was not independent as defined under Sections 303A.04 and 303A.05 of the NYSE rules, which govern nominating/corporate governance committees and compensation committees, respectively. As of
December 31, 2015, each of our nominating committee and compensation committee was comprised entirely of independent members; however because of the exemptions available to us as a foreign private issuer, we cannot assure you that we will comply
with all of the NYSE corporate governance rules in the future. As a result, you may not have the same protections afforded to stockholders of companies that are not foreign private issuers. For an overview of our corporate governance principles, see
Item 16G Corporate Governance.

You may be unable to enforce judgments obtained in U.S. courts against us.

We are incorporated under the laws of The Netherlands, and all or a substantial portion of our assets are located outside of the
United States and certain of our directors and officers and certain other persons named in this annual report are, and will continue to be, non-residents of the United States. As a result, although we have appointed an agent for service of process
in the United States, it may be difficult or impossible for United States investors to effect service of process within the United States upon us or our non-U.S. resident directors and officers or to enforce in the United States any judgment against
us or them including for civil liabilities under the United States securities laws. Any judgment obtained in any United States federal or state court against us may, therefore, have to be enforced in the courts of The Netherlands, or such other
foreign jurisdiction, as applicable. Because there is no treaty or other applicable convention between the United States and The Netherlands with respect to legal judgments, a judgment rendered by any United States federal or state court will not be
enforced by the courts of The Netherlands unless the underlying claim is relitigated before a Dutch court. Under current practice, however, a Dutch court will generally grant the same judgment without a review of the merits of the underlying claim
(i) if that judgment resulted from legal proceedings compatible with Dutch notions of due process, (ii) if that judgment does not contravene public policy of The Netherlands and (iii) if the jurisdiction of the United States federal
or state court has been based on grounds that are internationally acceptable. Investors should not assume, however, that the courts of The Netherlands, or such other foreign jurisdiction, would enforce judgments of United States courts obtained
against us predicated upon the civil liability provisions of the United States securities laws or that such courts would enforce, in original actions, liabilities against us predicated solely upon such laws.

We incur increased costs as a result of being a public company.

As a listed public company, we incur additional legal, accounting, insurance and other expenses than we would have incurred as a private
company. We incur costs associated with our public company reporting requirements. In addition, the Sarbanes-Oxley Act and related rules implemented by the U.S. Securities and Exchange Commission (the SEC) and the NYSE have imposed
increased regulation and required enhanced corporate governance practices for public companies. Our efforts to comply with evolving laws, regulations and standards in this regard are likely to result in increased general and administrative expenses
and a diversion of management time and attention from revenue generating activities to compliance activities. We also expect these new rules and regulations to make it more expensive for us to obtain director and officer liability insurance, and we
may be required to accept reduced policy limits and coverage or incur substantially higher costs to obtain the same or similar coverage.

If our internal controls over financial reporting are found to be ineffective, our financial results or our stock price may be adversely
affected.

Our most recent evaluation of our internal controls resulted in our conclusion that, as of December 31, 2015, our
internal controls over financial reporting were effective. Our ability to manage our operations and growth, and other systems upgrades designed to support our growth, will require us to develop our controls and reporting systems and implement or
adopt new controls and reporting systems. If in the future our internal control over financial reporting is found to be ineffective, or if a material weakness is identified in our controls over financial reporting, our financial results may be
adversely affected. Investors may also lose confidence in the reliability of our financial statements which could adversely affect our stock price.

ITEM 4: INFORMATION ON THE COMPANY

Overview

We are a leading provider of
carrier and cloud neutral colocation data center services in Europe. We support approximately 1,600 customers through 41 data centers in 11 countries enabling them to physically protect, connect, process and distribute their most valuable
information. Within our data centers, we enable our customers to connect to a broad range of telecommunications carriers, Internet service providers and other customers. Our data centers act as content, cloud and connectivity hubs that facilitate
the processing, storage, sharing and distribution of data, content, applications and media between carriers and customers, creating an environment that we refer to as a community of interest.

Our core offering of carrier and cloud neutral colocation services includes space, power, cooling and a physically secure environment in which
to house our customers computing, network, storage and IT infrastructure. We enable our customers to reduce operational and capital costs while improving application performance and flexibility. We supplement our core colocation offering with
a number of additional services, including network monitoring, remote monitoring of customer equipment, systems management, engineering support services, cross connects, data backup and storage.

We are headquartered near Amsterdam, The Netherlands, and we operate in major metropolitan areas, including Amsterdam, Frankfurt, Paris and
London, the main data center markets in Europe. Our data centers are located in close proximity to the intersection of telecommunications fiber routes, and we house more than 600 individual carriers and Internet service providers, 20 European
Internet exchanges and all the leading cloud platforms. Our data centers allow our customers to lower their telecommunications costs and reduce latency, thereby improving the response time of their applications. This high level of connectivity
fosters the development of communities of interest.

Strategy

Target New Customers in High Growth Industry Segments to Further Develop our Communities of Interest

We categorize our customers into industry segments, and we will continue to target new customers in high growth industry segments, including
financial services, cloud and managed services providers, digital media and carriers. Winning new customers in these target industries enables us to expand existing, and build new, high value communities of interest within our data centers. For
example, customers in the digital media segment benefit from the close proximity to content delivery network providers and Internet exchanges in order to rapidly deliver content to consumers. We expect the high value and reduced cost benefits of our
communities of interest to continue to attract new customers, which will lead to decreased customer acquisition costs for us.

Increase Share of Spend from Existing Customers

We focus on increasing revenue from our existing customers in our target market segments. New revenue from our existing customers comprises a
substantial portion of our new business, generating the majority of our new bookings. Our sales and marketing teams focus on proactively working with customers to identify expansion opportunities in new or existing markets.

Maintain Connectivity Leadership

We seek to increase the number of carriers in each of our data centers by expanding the presence of our existing carriers into additional data
centers and targeting new carriers. We also will continue to develop our relationships with Internet exchanges and work to increase the number of Internet service providers in these exchanges. In countries where there is no significant Internet
exchange, we will work with Internet service providers and other parties to create the appropriate Internet exchange. Our carrier sales and business development team will continue to work with our existing carriers and Internet service providers,
and target new carriers and Internet service providers, to maximize our share of their data center spend, and to achieve the highest level of connectivity in each of our data centers, with the right carriers to support the requirements of each of
our communities of interest.

Continue to Deliver Best-in-Class Customer Service

We will continue to provide a high level of customer service in order to maximize customer satisfaction and minimize churn. Our European
Customer Service Center operates 24 hours a day, 365 days a year, providing continuous monitoring and troubleshooting and giving our customers one call access to full, multilingual technical support, thereby reducing our customers internal
support costs. In addition, we will continue to develop our customer tools, which include an online customer portal to provide our customers with real-time access to information. We will continue to invest in our local service delivery and assurance
teams, which provide flexibility and responsiveness to customer needs.

Disciplined Expansion and Conservative Financial Management

We plan to invest in our data center capacity, while maintaining our disciplined investment approach and prudent financial policy. We will
continue to determine the size of our expansions based on selling patterns, pipeline and trends in existing demand as well as working with our customers to identify future capacity requirements. We only begin new expansions once we have identified
customers and we have the capital to fully fund the build out, with the goal of selling 25% of a data centers space by its opening. Our expansions are done in phases in order to manage the timing and scale of our capital expenditure
obligations, reduce risk and improve our return on capital, with a target internal rate of return in excess of 30%. Finally, we will continue to manage our capital deployment and financial management decisions based on adherence to our target
internal rate of return on new expansions and target leverage ratios. For a description of past and current capital expenditures, see Item 5 Operating and Financial Review and Prospects.

Our Services

We offer carrier and cloud
neutral colocation data center and managed services to our customers.

Colocation

Our colocation services provide clients with the space and power to deploy IT infrastructure in our world-class data centers. Through a number
of redundant subsystems, including power, fiber and cooling, we are able to provide our customers with highly reliable services. Our colocation services are scalable, allowing our customers to upgrade space, connectivity and services as their
requirements evolve. Our data centers employ a wide range of physical security features, including biometric scanners, man traps, smoke detection, fire suppression systems, and secure access. We provide colocation services including:

Space

Each of our data
centers houses our customers IT infrastructure in a highly connected facility, designed and outfitted to ensure a high level of network reliability. This service provides space and power to our clients to deploy their own IT infrastructure.
Customers can choose individual cabinets or a secure cage or an individual room depending on their space and security requirements.

Power

Each of our data
centers is equipped to offer our customers high power availability. Since the availability of power is essential to the operation of our data centers, we provide power backup in case of outage as the availability of power is essential to the
operation of a data center. The majority of our data centers have redundant grid connections and all of our data centers have a power backup installation in case of outage. Generators in combination with uninterrupted power supply, or UPS, system,
endeavor to ensure maximum availability. We provide a full range of output voltages and currents and we offer our customers a choice of guaranteed levels of availability between 99.9% and 99.999%.

Connectivity

We provide
connectivity services that allow our customers to connect their IT infrastructure to exchange traffic and access cloud platforms. These services offer connectivity with more than 600 telecommunications carriers and all the leading cloud providers,
thus allowing our customers to reduce costs while enhancing the reliability and performance associated with the exchange of Internet and cloud data traffic. Our connectivity options offer our customers a key strategic advantage by providing direct,
high-speed connections to peers, partners, customers, cloud platforms and some of the most important sources of IP data, content and distribution in the world.

Cross Connect

We install
and manage physical connections running from our customers equipment to the equipment of our telecommunications carrier, Internet service providers and Internet exchange customers as well as other customers. Cross connects are physically
secured in dedicated areas called Meet-Me rooms. Our staff test and install cables and patches and maintain cable trays and patch panels according to industry best practice.

Managed Services

In
addition to providing colocation services, we provide a number of additional managed services, including systems monitoring, systems management, engineering support services, data back-up and storage. Some managed services are only performed on an
ad hoc basis, as and when requested by the customer, while others are more recurring in nature. These services are provided either by us directly, or in conjunction with third parties.

Customer service is provided locally by our in-country teams and centrally via our European Customer Service
Center located in London. The European Customer Service Center supports five European languages (Dutch, English, French, German and Spanish) and is run by technical support staff and operates 24 hours a day, 365 days a year, in order to provide
rapid and cost-effective technical and business support to all of our clients. In addition to its service desk functions, the European Customer Service Center monitors and manages the performance of our data centers and takes care of network
monitoring and other network operations center functions. The European Customer Service Center arranges, as necessary, local engineering support, rapid response (out of hours emergency assistance), backup and restore and other managed
services. There is also a customer relationship management system in place to electronically log each issue that the European Customer Service Center is requested to address to ensure efficient and timely support.

Customer Contracts

Our customers
typically sign contracts for the provision of colocation space together with basic service level agreements that provide for support services and other managed services. Unless customers notify us of their intention to terminate, which is typically
90 days in advance of the end of the contract period, contracts (a majority of which have an initial term of three to five years) typically renew constantly and automatically for successive one year periods. However, where beneficial to us we will,
prior to the expiry of a customer contract, seek to re-negotiate and re-sign with a customer (generally for a minimum one-year period). Our contracts generally allow us the option to increase prices in accordance with local price indices in each
jurisdiction and we are able to adjust the amount charged for power at any time and as frequently as necessary during the life of the contract to account for any increases in power costs we are charged by our suppliers or governmental surcharges.

Contracts for colocation services are priced on the basis of a monthly recurring fee reflecting charges for space, power used in the
common parts of the data center, power plugs and metered power usage, with related infrastructure and implementation costs included in an initial set-up fee. Clients have two options with respect to power usage: either (i) to pay
for power usage in plugs in advance (typically included in the total cabinet price), which are contractually defined amounts of power per month, for which the customer must pay in full, regardless of how much power is actually used; or
(ii) to pay for their actual power usage in arrears on a metered basis. The first option (power plugs) is usually sold in shared areas of our data centers where customers pay per cabinet. The second option (metered power usage) is usually sold
to customers taking dedicated space such as a cage, suite or private room where they are charged on a per square meter basis.

As with colocation services, our managed services are typically contracted on the basis of an
annual contract (or longer where appropriate) and the fee generally consists of monthly recurring charges and usage based charges as appropriate, and may also include an initial set-up fee. If managed services are ad hoc in nature, they are invoiced
on completion of the service.

Each new customer contract we enter into provides that in the event of a power outage or other equivalent
service level agreement breach (e.g. for repeatedly crossing a temperature or humidity benchmark), the customer will receive a service credit in the form of a reduction in its next service fee payment, the credit being on a sliding scale to reflect
the seriousness of the breach. Our customer contracts typically exclude liability for consequential or indirect loss suffered as a result of a service level agreement breach and for force majeure. Historically, our penalty payments under our service
level agreements have been minimal.

Customer Accounts

Fees are typically invoiced quarterly in advance, with the exception of metered power usage which is invoiced monthly in arrears. On new
contracts, we generally require deposits, which we are able to use to cover any non-payment of invoices. If accounts are not paid on time, we ultimately seek recovery through the court system.

Sales and Marketing

Our sales and
marketing teams focus on proactively identifying and converting opportunities for both existing customers and prospects within our target segments, to expand customers space within our data center portfolio.

Sales

We sell our
products and services through local direct sales forces and a centralized International Accounts Team and by attending tradeshows, networking events and industry seminars. Our International Accounts Team focuses on maximizing revenues across our
European footprint from our largest customers and on identifying and developing new major accounts. We utilize a number of indirect channel partners in the United States to secure both referrals and orders from companies based out of the United
States.

Marketing

Our marketing organization is responsible for identifying target customer segments, development of the value proposition that will enable us to
succeed in our chosen segments, building and communicating a distinct brand, driving qualified leads into the sales pipeline and ensuring strategic alignment with key partners. Our marketing team supports our strategic priorities through the
following primary objectives:

Customer Segmentation

Our marketing organization is responsible for the identification of high-growth customer segments and associated companies therein that we wish
to target in order to build the community of interest and develop our value proposition to enable success in our chosen markets. Our marketing organization is also responsible for business development of key magnetic and strategic accounts in each
segment working with sales in order to build our communities of interest. Magnetic companies when present in our data centers, attract other interested members to join the community. The magnetic effect can be a consequence of the application,
data or capability that they place in our data centers. A company in one of our segments is considered strategic if its presence adds value to the community of interest by increasing the magnetism of the community. This can be
achieved by virtue of its brand and the associated added value to Interxion and the community.

Brand Management and Positioning

This includes brand identity unification, positioning at the corporate and country levels, the development of methodology, marketing
assets and brand awareness programs for all of our business units.

Lead Generation

Utilizing online marketing, targeted advertising, direct marketing, event marketing and public relations programs and strategies to design and
execute successful lead-generation campaigns leveraging telemarketing and direct sales to grow our pipeline and deliver our revenue goals.

Employees

As of December 31, 2015 we had a total of 533 employees (full time equivalents, excluding contractors and interim staff) of which
323 employees worked in operations and support, 105 employees worked in sales and marketing and 105 employees served general and administrative roles. Of our employees, 400 were based in countries where we have operations and 133 employees worked
from our headquarters near Amsterdam and corporate offices in London as of December 31, 2015. We believe that relations with our employees are good. Except for collective rights granted by local law, none of our employees are subject to
collective bargaining agreements.

Leases

We hold title to certain of our properties and lease the remainder. We exercised certain purchase options and agreed to purchase the PAR7 and
AMS7 properties, which are currently reported as financial leases, and they will be reported as such until the acquisitions complete. For the other leased properties on which our data centers are located, we generally seek to secure property leases
for terms of 20 to 25 years. Where possible, we try to mitigate the long-term financial commitment by contracting for initial lease terms for a minimum period of 10 to 15 years with the option for us to either (i) extend the leases for additional
five-year terms or (ii) terminate the leases upon expiration of the initial 10 to 15 year term. Our leases generally have consumer price index based annual rent increases over the full term of the lease.

Data Center Operations

We have 41
carrier and cloud neutral colocation data centers in 13 metropolitan areas in 11 countries, representing approximately 111,900 square meters of maximum equippable space (as of December 31, 2015). Maximum equippable space is the maximum amount
of space in our data centers which is designed to be used and sold as Equipped Space.

All of our data centers are located in Europe and
all of our revenues are generated in Europe. For more information on the geographic breakdown of our revenues, see Note 5 of our 2015 consolidated financial statements, included elsewhere herein.

We select sites for our data centers based primarily on expected customer demand, availability of power and access to telecommunications fiber
routes. Most of our data centers are stand-alone structures, close to power sub-stations and telecommunication networks in light industrial areas outside of city centers, rather than residential areas where more prohibitive environmental regulations
exist. Data center design and development is a highly complex process. Data center construction requires extensive planning and must navigate regulatory procedures which can vary by jurisdiction. We have developed extensive technical experience in
building data centers in Europe and we are well-positioned to bring new data centers to market rapidly to meet customer demand.

Please see Item 3 Key InformationRisk FactorsWe face significant competition and we may not be able to compete
successfully against current and future competitors.

Litigation

We have not been party to any legal proceedings, governmental or arbitration proceedings during the twelve months preceding the date of this
annual report which may have, or have had in the recent past, a significant effect on our financial position.

Regulation

Although we are not subject to any financial regulations (such as outsourcing requirements, MiFID or Basel II), our financial services
customers commonly are. In their contracts with us, these financial services customers impose access, audit and inspection rights to those parts of our data centers that contain their equipment so that they can satisfy their regulatory requirements.

In addition, as a consumer of substantial amounts of electricity, we are affected by the CRC Energy Efficiency Scheme (the CRC
Scheme), which was introduced in 2010, and simplified in May 2013 by the CRC Energy Efficiency Scheme Order 2013. It is a mandatory UK-wide emissions trading scheme based on electricity usage. Phase 2 runs from April 1, 2014 to March 31, 2019.
For Phase 2 of the CRC Scheme, organizations qualified if, during the qualification year (that ran from April 1, 2012 until March 31, 2013) , they consumed over 6,000 MWh of qualifying electricity through at least one settled half hour meter. We
qualified for the CRC Scheme and registered for Phase 2 with the CRC Registry by the deadline of January 31, 2014. Non-compliance with the CRC Scheme may result in criminal and civil penalties.

Once registered for Phase 2, participants have to monitor and report their annual supplies of
electricity and gas and then surrender allowances equal to the quantity of carbon dioxide emissions associated with that annual CRC Scheme consumption before the end of October. One allowance must be surrendered for each ton of carbon
dioxide emitted. Allowances can be bought or traded and participants must submit an annual report on their CRC energy supplies by the end of July each year. The allowance price in the April 2014 forecast sale for 2014/2015 was
£15.60 per ton of carbon dioxide and was £16.40 per ton in the buy to comply sale in June 2015. The allowance price for 2015/16 was £15.60 per ton in the April 2015 forecast sale and will be £16.90 per
ton in the buy to comply sale in June 2016. Through the annual report publication, the U.K. Environmental Agency also publishes information on the basis of participants annual reports including details the participants submitted
when they registered for the CRC Scheme. The potential impacts of the CRC Scheme on our data centers in the UK include the costs of improving energy efficiency in order to reduce electricity consumption and the costs of allowances and administration
in complying with the CRC Scheme.

Climate Change Agreements (CCAs) are voluntary agreements between the UK Government and
energy intensive sectors allowing a discount from the UK climate change levy (which is a tax added to electricity and fuel bills) in return for companies meeting carbon saving targets. Data center businesses providing colocation space (both
wholesale and retail) have been eligible for CCAs since July 2014, when the data center sector association, techUK, signed an umbrella agreement with the UK Environment Agency. CCA targets are due to be revised in 2016. From April 1, 2013,
participants are entitled to a 90% reduction on the electricity climate change levy and a 65% reduction for other fuels if they agree to and meet their CCA targets. We signed a CCA in February 2015.

Within this CCA framework, the CRC Scheme provides that an electricity or gas supply consumed for the purpose of operating a participating CCA
facility will not qualify as an energy supply requiring surrender of carbon dioxide allowance under the CRC Scheme. While we now face costs associated with meeting the target in our CCA, the CCA has reduced our expenditure on CRC Scheme allowances
and allows us to qualify for the reduced UK climate change levy (CCL) rate under Part IV of Schedule 6 to the Finance Act 2000 (as amended).

Changes to the UK environmental regulations are expected in the future. The UK government consulted on reforming business energy efficiency
taxation in autumn 2015, and HM Treasury published its response to that consultation in March 2016 and announced that it will close the CRC Scheme following the 2018-2019 compliance year, with no purchase of allowances required to cover emissions
for energy supplied from April 2019. The last CRC report should therefore be by the end of July 2019 and the last surrender of allowances for emissions from energy supplied in 2018-2019 compliance year should be by the end of October 2019. The UK
government will consult later in 2016 on a new, simplified energy and carbon reporting framework for introduction by April 2019. The main rates of the CCL will increase from April 2019, but the UK government will keep existing CCA eligibility
criteria in place until at least 2023 and increase the CCL discount available to CCA participants from April 2019 to ensure they pay no more than a Retail Price Index level increase. There is also expected to be a CCL target review commencing in
2016 and a rebalancing of CCL rates for different fuel types to encourage a reduction in gas consumption. We will continue to analyze all proposed changes fully and prepare to comply with any new requirement and/or legal obligations.

Pursuant to Article 8(4-6) of the Energy Efficiency Directive 2012 (aiming to encourage investment in energy efficiency improvements, as part
of the European Unions aim to reduce primary energy consumption by 20% by 2020), European Member States are obliged to ensure that undertakings that meet certain thresholds regarding the number of employees, annual balance sheet total and
annual turnover qualify as specified in Energy Efficiency Directive 2012 carry out energy audits. The directive requires the audits to be carried out at least every four years, and set a first compliance deadline of December 5, 2015. The directive
does allow alternatives to the audit, such as ISO 50001 certification. If a qualifying undertaking does not comply with its obligations under national legislation, the relevant compliance body may issue sanctions (for example, in the UK, the
regulator can issue an enforcement notice and seek civil penalties). Costs associated with ESOS include the costs of the ESOS assessments and then voluntary costs of implementing any energy efficiency measures identified.

We meet the qualification thresholds in the UK, Germany, France, Denmark, Sweden and the Netherlands.

In Germany, in accordance with national legislation, we are exempt from performing an energy efficiency audit due to our ISO 50001
certification. We have informed the relevant authority accordingly. In the Netherlands and France we have finalized our audit reports. Both audit reports have been filed with relevant authority in a timely fashion. In Denmark the audit and the audit
report need to be finalized and filed before the end of the first quarter of 2016. We are currently in the process of performing the audit and expect to file the audit report before the deadline. In Sweden the audit and the audit report need to be
finalized and filed before the end of the first quarter of 2017. We are currently in the process of performing the audit and expect to file the audit report before the deadline. In the UK, an audit has been performed and the audit report has been
finalized. The relevant authority is notified thereof in a timely manner.

##### Table of Contents

As an operator of data centers which act as content and connectivity hubs that facilitate the
storage, sharing and distribution of data, content and media for customers, we have in place an Acceptable Use Policy which applies to all of our customers using Internet connectivity services provided by us and which requires our customers to
respect all legislation pertaining to the use of Internet services, including email.

We are subject to telecommunications regulation in
the various European jurisdictions in which we presently operate, most notably the EU Regulatory Framework. Under these regulations, we are not required to obtain licenses for the provision of our services. However, we may be required to notify the
national telecommunications regulator in certain European jurisdictions about these services. We have made the necessary notifications for such jurisdictions.

By operating data centers, we will process personal data under the EU Data Protection Directive (95/46/EC). This directive is implemented
through adoption in local legislation of the EU member states. We are subject to this legislation in most European jurisdictions as processors and controllers in the meaning of this Directive. This may impose obligations on us, such as an obligation
to take reasonable steps to protect that information.

On December 13, 2013, we were awarded a permit by the Seine-St-Denis authorities to
operate our PAR7 data center. On October 15, 2015, a French administrative court ruled that local authorities failed to perform a sufficiently extensive study of the potential noise impact that operating the PAR7 data center could have on local
residents and consequently the French administrative court annulled the permit we received on December 13, 2013. We have appealed this ruling. The Seine-St-Denis authorities have requested that we re-apply for a new permit and on March 2, 2016 we
submitted an application for a new permit with the relevant administrative authorities. We have worked with the Seine-St-Denis authorities and we obtained formal approval to continue to operate the PAR7 data center during the application process,
which we expect to conclude by the end of 2016.

Insurance

We have in place insurance coverage which we consider to be reasonable and against the type of risks usually insured by companies carrying on
the same or similar types of business as ours in the markets in which we operate. Our insurance broadly falls under the following four categories: professional indemnity, general third party liability, directors and officers liability and property
damage insurance and business interruption insurance.

Our History and Organizational Structure

European Telecom Exchange BV was incorporated on April 6, 1998, which (after being renamed InterXion Holding B.V. on June 12, 1998)
was converted into InterXion Holding N.V. on January 11, 2000. For further information on the history and development of the Company, see Item 10 Additional InformationGeneral. From inception onwards we have grown our
colocation business organically. Since 2001, we have developed our geographic footprint in 13 cities where we have established data center campuses. The only changes to our geographic footprint have been very recent  we added Marseille in 2014
and exited Hilversum at the end of 2014. Following the industry downturn beginning in 2001 as a result of a sharp decline in demand for Internet-based businesses, we restructured within our geographic base to refocus on a broader and more stable
customer base. We have since focused on shifting our customer base from primarily emerging Internet companies and carriers to a wide variety of established businesses seeking to house their IT infrastructure.

ITEM 5: OPERATING AND FINANCIAL REVIEW AND PROSPECTS

The following information should be read in conjunction with the audited consolidated financial statements and notes thereto and with the
financial information presented in Item 18 Financial Statements included elsewhere in this annual report. The following discussion contains forward-looking statements that reflect our plans, estimates and beliefs. Such statements
are based upon current expectations that involve risks and uncertainties. Any statements contained herein that are not statements of historical fact may be deemed to be forward-looking statements. For example, the words believes,
anticipates, plans, expects, intends and similar expressions are intended to identify forward-looking statements. Our actual results could differ materially from those discussed in these
forward-looking statements. Factors that might cause such a discrepancy include, but are not limited to, those discussed in Liquidity and Capital Resources below and Item 3 Key InformationRisk Factors above.
All forward-looking statements in this annual report are based on information available to us as of the date of this annual report and we assume no obligation to update any such forward-looking statements.

Overview

We are a leading provider of
carrier and cloud neutral colocation data center services in Europe. We support approximately 1,600 customers through 41 data centers in 11 countries enabling them to physically protect, connect, process and distribute their most valuable
information. Within our data centers, we enable our customers to connect to a broad range of telecommunications carriers, Internet service providers and other customers. Our data centers act as content, cloud and connectivity hubs that facilitate
the processing, storage, sharing and distribution of data, content, applications and media between carriers and customers, creating an environment that we refer to as a community of interest.

Our core offering of carrier and cloud neutral colocation services includes space, power, cooling and a physically secure environment in which
to house our customers computing, network, storage and IT infrastructure. We enable our customers to reduce operational and capital costs while improving application performance and flexibility. We supplement our core colocation offering with
a number of additional services, including network monitoring, remote monitoring of customer equipment, systems management, engineering support services, cross connects, data backup and storage.

We are headquartered near Amsterdam, The Netherlands, and we operate in major metropolitan areas, including Amsterdam, Frankfurt, Paris and
London, the main data center markets in Europe. Our data centers are located in close proximity to the intersection of telecommunications fiber routes, and we house more than 600 individual carriers and Internet service providers, 20 European
Internet exchanges and all the leading cloud platforms. Our data centers allow our customers to lower their telecommunications costs and reduce latency, thereby improving the response time of their applications. This high level of connectivity
fosters the development of communities of interest, which are important to customers in each of our industry segments: network providers, managed services providers (including cloud service providers), enterprises, financial services and digital
media. Development of our communities of interest generates network effects for our customers that enrich the value and attractiveness of the community to both existing and potential customers.

Growth in Internet traffic, cloud computing and the use of customer-facing hosted applications are driving significant demand for high quality
carrier and cloud neutral colocation data center services. This demand results from the need for either more space or more power, or both. These needs, in turn, are driven by, among other factors, decreased cost of Internet access, increased
broadband penetration, increased usage of high-bandwidth content, increased number of wireless access points and growing availability of Internet and network based applications. If the global economys recovery stalls or is reversed, global IP
traffic may grow at a lesser rate, which could lead to a slowdown in the increase in demand for our services.

Our ability to meet the
demand for high quality carrier and cloud neutral colocation data center services depends on our ability to add capacity by expanding existing data centers or by locating and securing suitable sites for additional data centers that meet our
specifications, such as proximity to numerous network service providers, access to a significant supply of electrical power and the ability to sustain heavy floor loading.

Our market is highly competitive. Most companies operate their own data centers and in many cases continue to invest in data center capacity,
although there is a trend towards outsourcing. We compete against other carrier and cloud neutral colocation data center service providers, such as Equinix Telecity, formerly Equinix and TelecityGroup, which merged in January 2016, and Telehouse. We
also compete with other types of data centers, including carrier-operated colocation, wholesale and IT outsourcers and managed services provider data centers. The cost, operational risk and inconvenience involved in relocating a customers
networking and computing equipment to another data center are significant and have the effect of protecting a competitors data center from significant levels of customer churn.

Key Aspects of Our Financial Model

We offer carrier and cloud neutral colocation services to our customers. Our revenues are mostly recurring in nature and in the last several
years, Recurring Revenue has consistently represented over 90% of our total revenue. Our contracted Recurring Revenue model together with low levels of Average Monthly Churn provide significant predictability of future revenue.

Revenue

We generally enter into
contracts with our customers for initial terms of generally three to five years, with annual price escalators and with automatic one-year renewals after the end of the initial term. Our customer contracts provide for a fixed monthly recurring fee
for our colocation, managed services and, in the case of cabinets, fixed amounts of power pre-purchased at a fixed price. These fees are billed monthly, quarterly or bi-annually in advance, together with fees for other services such as the provision
of metered power (based on a price per kilowatt hour actually consumed), billed monthly in arrears, or fees for services such as remote hands and eyes support, billed on an as-incurred basis.

The following table presents our future committed revenues expected to be generated from our fixed term customer contracts as of
December 31, 2015, 2014 and 2013.

Revenues are recognized when it is probable that future economic benefits will flow to the Group and that
these benefits, together with their related costs, can be measured reliably. Revenues are measured at the fair value of the consideration received or receivable taking into account any discounts or volume rebates.

The Group reviews transactions for separately identifiable components of revenue and if necessary applies individual recognition treatment, in
which revenues are allocated to separately identifiable components based on their relative fair values.

The Group earns colocation
revenue as a result of providing data center services to customers at its data centers. Colocation revenues and lease income are recognized in profit or loss on a straight-line basis over the term of the customer contract. Incentives granted are
recognized as an integral part of the total income, over the term of the customer contract. Customers are usually invoiced quarterly in advance and income is recognized on a straight-line basis over the quarter. Initial setup fees payable at the
beginning of customer contracts are deferred at inception and recognized in profit or loss on a straight-line basis over the initial term of the customer contract. Power revenues are recognized based on customers usage and are generally
matched with the corresponding costs.

Other services revenue, including managed services and customer installation services, including
equipment sales, are recognized when the services are rendered. Certain installation services and equipment sales, which by their nature are non-recurring, are presented as non-recurring revenues and are recognized upon delivery of service.

Deferred revenues relating to invoicing in advance and initial setup fees are carried on the statement of financial position as part of trade
payables and other liabilities. Deferred revenues due to be recognized after more than one year are held in non-current liabilities.

Recurring Revenue comprises revenue that is incurred monthly from colocation, connectivity and associated power charges, office space,
amortized set-up fees and certain recurring managed services (but excluding any ad hoc managed services) provided by us directly or through third parties. Rents received for the sublease of unused sites are excluded.

Costs

Our cost base consists primarily of personnel, power and property costs.

We employ the majority of our personnel in operations and support roles that operate our data centers 24 hours a day, 365 days a year. As of
December 31, 2015 we employed 533 full-time equivalent employees: 323 in operations and support; 105 in sales and marketing; and 105 in general and administrative roles. A data center typically requires a fixed number of personnel to run,
irrespective of customer utilization. Increases in operations and support personnel occur when we bring new data centers into service. Our approach is, where possible, to locate new data centers close to our existing data centers. In addition to
other benefits of proximity, in some cases it also allows us to leverage existing personnel within a data center campus.

In 2015, 2014
and 2013, we invested resources in sales and marketing personnel to engage with our existing and potential customers on an industry basis. This has enabled us to establish closer relationships with our customers thereby allowing us to understand and
anticipate their needs and to forecast demand, helping us plan the scope and timing of our expansion activities.

Our customers
equipment consumes significant amounts of power and generates heat. In recent years the amount of power consumed by an individual piece of equipment, or power density, has increased as processing capacity has increased. In maintaining the correct
environmental conditions for the equipment to operate most effectively, our cooling and air conditioning infrastructure also consumes significant amounts of power. Our power costs are variable and directly dependent on the amount of power consumed
by our customers equipment. Our power costs also increase as the Utilization Rate of a data center increases. Increases in power costs due to increased usage by our customers are generally matched by corresponding increases in power revenues.

The unit price we pay for our energy also has an impact on our energy costs. We generally enter into contracts with local utility
companies to purchase energy at fixed prices for periods of one or two years. Within substantially all of our customer contracts, we have the right to adjust at any time the price we charge for our power services to allow us to recover increases in
the unit price we pay.

We currently hold title to the AMS3, AMS6, BRU1, CPH2, FRA8, FRA10, MRS1, PAR3, PAR5 and VIE properties. We
completed the acquisition of the VIE properties and terminated the VIE financial lease in January 2015. In June 2015 we finalized the development of the building that will house the FRA10 data center. This building is located on freehold landed
owned by us.

We also exercised certain purchase options and agreed to purchase the PAR7 freehold land on which we own the PAR7 data
center, and the AMS7 freehold land and properties. The PAR7 and AMS7 properties are currently reported as financial leases, and they will be reported as such until the acquisitions complete.

For the other leased properties on which our data centers are located, we generally seek to secure property leases for terms of 20 to 25
years. Where possible, we try to mitigate the long-term financial commitment by contracting for initial lease terms for a minimum period of 10 to 15 years with the option for us to either (i) extend the leases for additional five-year terms or (ii)
terminate the leases upon expiration of the initial 10 to 15 year term. Our leases generally have consumer price index based annual rent increases over the full term of the lease.

Larger increases in our property costs occur when we bring new data centers into service. Bringing new data centers into service also has the
effect of temporarily reducing our overall Utilization Rate while the utilization of the new data center increases as we sell to customers.

In addition, we enter into annual maintenance contracts with our major plant and equipment suppliers. This cost increases as new maintenance
contracts are entered into in support of new data center operations.

Operating Leverage

Due to the relatively fixed nature of our costs, we generally experience margin expansion as our Utilization Rate at existing data centers
increases. Our margins and the rate of margin expansion will vary based upon the scope and scale of our capacity expansions, which affects our overall Utilization Rate.

EBITDA, Adjusted EBITDA and Adjusted EBITDA margin

We present EBITDA, Adjusted EBITDA and Adjusted EBITDA margin as additional information because we understand that they are measures used by
certain investors and because they are used in our financial covenants in our 100.0 million Revolving Facility Agreement and the 475.0 million 6.0% Senior Secured Notes due 2020. However, other companies may present EBITDA,
Adjusted EBITDA and Adjusted EBITDA margin differently than we do. EBITDA, Adjusted EBITDA and Adjusted EBITDA margin are not measures of financial performance under IFRS and should not be considered as an alternative to operating profit or as a
measure of liquidity or an alternative to net income as indicators of our operating performance or any other measure of performance derived in accordance with IFRS.

We define EBITDA as operating profit plus depreciation, amortization and impairment of assets. We
define Adjusted EBITDA as EBITDA adjusted to exclude share-based payments, M&A transaction costs, increase/decrease in provision for onerous lease contracts, M&A transaction break fee income, and income from sub-leases of unused data center
sites. Adjusted EBITDA margin is defined as Adjusted EBITDA as a percentage of revenue.

Onerous lease contracts are those in which we
expect losses to be incurred in respect of unused data center sites over the term of the lease contract. Provisions for these leases are based upon the present value of the future contracted payout under these leases, and movements in the provision
for onerous lease contracts are reflected on our income statement. We sublease portions of these unused sites to third parties and treat the income from these subleases as other income.

The provision for onerous lease contracts relates to two unused data center sites in Germany, one in Munich which was terminated in March
2016and one in Dusseldorf terminating in August 2016; therefore, the remaining part of the provision for onerous lease contracts is presented as current.

Net Finance Expense

Towards the end of
2006, we started an expansion program of our data centers based on customer demand. This expansion program, closely matched to both customer demand and available capital resources, has continued since that time. We do not commit to a phase of an
expansion or construction of a data center unless we have cash and committed capital available to complete the phase. Since 2006, we have raised debt capital to fund our expansion program, and this has contributed to increases in our finance
expense. During the period of construction of a data center, we capitalize the borrowing costs as part of the construction costs of the data center. We refinanced the Companys debt in February 2010 when we issued 200 million of 9.5%
senior secured notes, which was primarily used to repay existing debt, and a further tap offering of 60 million in November 2010. In 2013, we issued 325 million of 6.0% senior secured notes. The proceeds were used to purchase,
redeem and discharge the 260 million of 9.5% senior secured notes, pay fees and expenses incurred in connection with the refinancing, and for other general corporate purposes. In April 2014, we improved our funding to support growth by
issuing 150 million of 6.00% senior secured notes. This additional financing, combined with a 9.2 million mortgage for our BRU1 data center secured in 2014, was used to repay amounts drawn under our revolving facility and to fund further
expansion projects. In December 2015 we secured a new 15.0 million mortgage for our FRA8 and FRA10 property, which will be used for further expansion projects.

In the year ended December 31, 2015, our net finance expense was 29.0 million, which primarily consisted of interest expense of
32.3 million, profit from sale of a financial asset of 2.3 million and foreign currency exchange gains of 0.9 million. For the full year 2014, our net finance expense primarily consisted of interest expense of
26.3 million, refinancing expenses of 0.6 million and interest income of 0.9 million. For the full year 2013, our net finance expense primarily consisted of interest expense of 24.6 million, refinancing expenses of
31.0 million and interest income of 0.5 million. The increase in net finance expense for the year ended December 31, 2015 was due primarily to the full year impact of the 150 million Additional Notes issued in April 2014,
partly offset by decreased capitalization of borrowing costs during the construction of new data center space. We capitalized 2.6 million of borrowing costs in connection with the construction of new data center space in the year ended
December 31, 2015, 3.6 million in the year ended December 31, 2014 and 1.7 million in the year ended December 31, 2013.

We discuss our capital expenditures, including intangible assets and our capital expansion program below in Liquidity and Capital
Resources.

Income Tax Expense

Since inception we have generated significant tax loss carry forwards in all of our jurisdictions. In 2006, we became taxable income positive
and began offsetting our tax loss carry forwards against taxable profits. As of December 31, 2015 we have recognized a significant part of our tax loss carry forwards. We will continue to recognize the remaining deferred tax loss carry forwards
progressively as we become profitable in the respective jurisdictions. We expect to be able to continue to use our tax loss carry forwards to minimize cash taxes going forward.

Segment Reporting

We report our financials in two segments, which we have determined based on our management and internal reporting structure: the first being
France, Germany, The Netherlands and UK and the second being the Rest of Europe, which comprises our operations in Austria, Belgium, Denmark, Ireland, Spain, Sweden and Switzerland. Segment results, assets and liabilities include items directly
attributable to a segment as well as those that can be allocated on a reasonable basis. Unallocated items are presented as corporate and other and comprise mainly 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 center sites over the term of the relevant leases, as further explained below)
and revenue and expenses related to those onerous contracts, loans and borrowings and related expenses and income tax assets and liabilities. Segment capital expenditure, and intangible assets is the total cost directly attributable to a segment
incurred during the period to acquire property, plant and equipment.

Notes:

|(1) | The operating results for the year ended December 31, 2015 have been translated for convenience only based on the noon buying rate in The City of New York for cable transfers of euro as certified for customs
purposes by the Federal Reserve Bank of New York as of December 31, 2015 and for euro into U.S. dollars of 1.00 = U.S. 1.0859. See Item 3 Key InformationExchange Rate Information for additional information.
|--- | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

|(2) | We define EBITDA as operating profit plus depreciation, amortization and impairment of assets. We define Adjusted EBITDA as EBITDA adjusted to exclude share-based payments, M&A transaction costs, increase/decrease
in provision for onerous lease contracts, M&A transaction break fee income, and income from sub-leases of unused data center sites. Adjusted EBITDA margin is defined as Adjusted EBITDA as a percentage of revenue. We present EBITDA, Adjusted
EBITDA and Adjusted EBITDA margin as additional information because we understand that they are measures used by certain investors and because they are used in our financial covenants in our 100 million Revolving Facility Agreement and
475 million 6.00% Senior Secured Notes due 2020. Other companies, however, may present EBITDA, Adjusted EBITDA and Adjusted EBITDA margin differently than we do. EBITDA, Adjusted EBITDA and Adjusted EBITDA margin are not measures of
financial performance under IFRS and should not be considered as an alternative to operating profit or as a measure of liquidity or an alternative to net income as indicators of our operating performance or any other measure of performance derived
in accordance with IFRS. See EBITDA and Adjusted EBITDA for a more detailed description.

Notes:

|(1) | Equipped Space is the amount of data center space that, on the date indicated, is equipped and either sold or could be sold, without making any additional investments to common infrastructure. Equipped Space at a
particular data center may decrease if either (a) the power requirements of customers at such data center change so that all or a portion of the remaining space can no longer be sold as the space does not have enough power and/or common
infrastructure to support it without further investment or (b) if the design and layout of a data center changes to meet, among others, fire regulations or customer requirements, and necessitates the introduction of common space which cannot be
sold to individual customers, such as corridors.

|(2) | Utilization Rate is, on the relevant date, Revenue Generating Space as a percentage of Equipped Space; some Equipped Space is not fully utilized due to customers specific requirements regarding the layout of their
equipment. In practice, therefore, Utilization Rate may not reach 100%.

Years Ended December 31, 2015 and 2014

Revenue

Our revenue for the years ended
December 31, 2015 and 2014 was as follows:



|                      |  |                             |         |  |        |  |     |      |  |  |         |  |  |   |     |  |   |  |        |   |  |  |    |

Revenue increased to 386.6 million for the year ended December 31, 2015 from
340.6 million for the year ended December 31, 2014, an increase of 13%. Recurring revenue increased by 14% and non-recurring revenue remained stable at 6% of total revenues from the year ended December 31, 2014 to the year ended
December 31, 2015. The period over period growth in recurring revenue was primarily the result of an increase of approximately 8,100 square meters in Revenue Generating Space as a result of sales to both existing and new customers in all of our
regions.

Cost of Sales

Cost of
sales increased to 151.6 million for the year ended December 31, 2015 from 139.1 million for the year ended December 31, 2014, an increase of 9%. Cost of sales was 39% of revenue for the year ended December 31,
2015 and 41% for the year ended December 31, 2014. The increase in cost of sales related to our overall revenue growth and data center expansion projects, including (i) an increase of 5.9 million in energy usage costs and
(ii) an increase of 3.5 million higher cost for operation and support personnel commensurate with growth. Equipped Space increased by approximately 7,700 square meters during the year ended December 31, 2015 as a result of
expansions to existing data centers in Amsterdam, Vienna, Madrid, Marseille and Zurich, the construction of new data centers in Stockholm and Dusseldorf, and the closure of Hilversum. We expect cost of sales as a percentage of revenue to decrease as
we increase utilization at our existing facilities. This decrease may be offset by the impact of lower utilization in new data centers we open as part of our data center expansion projects.

Other Income

Other income represents
income that we do not consider part of our core business. It includes transaction break fee income and income from the subleases on unused data center sites.

Sales and Marketing Costs

Our sales and
marketing costs increased to 28.2 million for the year ended December 31, 2015 from 24.6 million for the year ended December 31, 2014, an increase of 15%. Sales and marketing costs were 7% of revenue for each of the
years ended December 31, 2015 and 2014.

The increase in sales and marketing costs was primarily a result of increased compensation
and related costs due to increases in employee headcount and marketing expenses associated with our continued strategy to invest in our industry-focused customer development and acquisition approach.

General and Administrative Costs

General
and administrative costs consist of depreciation, amortization and impairments, share-based payments, increase/(decrease) in provision for onerous lease contracts and other general and administrative costs.

Depreciation, amortization and impairments increased to 78.2 million for the year ended December 31, 2015 from
62.2 million for the year ended December 31, 2014, an increase of 26%. Depreciation, amortization and impairments was 20% of revenue for the year ended December 31, 2015 and 18% for the year ended December 31, 2014. The
increase was a result of new data centers and data center expansions.

In determining Adjusted EBITDA we add back share-based payments.
For the year ended December 31, 2015 we recorded share-based payments of 7.2 million, an increase of 9% from the year ended December 31, 2014. The increase was primarily due to new grants of options, restricted shares and
performance shares in 2015. In determining Adjusted EBITDA we also add back increase/(decrease) in provision for onerous lease contracts. Following our annual review of the provision for onerous lease contracts, the Company decreased the provision
by 0.2 million in 2015 while in 2014, the provision was decreased by 0.8 million. Finally, we also add back M&A transaction related costs and income, which included 9.1 million of income in 2015 and 0.3 million of
expenses in 2014.

Other general and administrative costs increased to 35.5 million for the year ended
December 31, 2015 from 30.6 million for the year ended December 31, 2014, an increase of 16%. Other general and administrative costs were 9% of revenue for the years ended December 31, 2015 and December 31, 2014. The
increase in the other general and administrative costs was due to both an increase of compensation costs principally resulting from an increase in salaries associated with an increased headcount and higher external hires and to an increase in the
costs for professional advisory services.

Net Finance Expense

Net finance expense increased to 29.0 million for the year ended December 31, 2015 from 27.9 million for the year
ended December 31, 2014, an increase of 4%. Net finance expense was 8% of revenue for the year ended December 31, 2015 and 8% of revenue for the year ended December 31, 2014. The increase in net finance expense for the year ended
December 31, 2015 was due primarily the result of the full year impact of the 150.0 million Additional Notes issued in April 2014 and lower capitalization of borrowing costs during the period of construction of new data center space. In
the year ended December 31, 2015 we capitalized 2.6 million compared to 3.6 million in the year ended December 31, 2014. Furthermore, the net finance expense is impacted by the gain on the sale of our financial asset in
2015, amounting to 2.3 million.

Income Taxes

Income tax expense was 17.9 million for the year ended December 31, 2015 compared to 15.4 million for the year ended
December 31, 2014. Income tax expense was 5% of revenue for the year ended December 31, 2015 and 5% of revenue for the year ended December 31, 2014. The increase in income tax expenses was primarily due to an increase in profit before
tax in 2015 as a result of the net impact of M&A transaction costs and M&A break fee related income. The effective income tax rate of 27% in the year ended December 31, 2015, compared to 31% for the year ended December 31, 2014, was
positively impacted by the recognition of previously unrecognized tax losses, profit mix and the change in certain tax rates.

We recorded
current tax expenses of 9.2 million for the year ended December 31, 2015 and 8.9 million for the year ended December 31, 2014. We recorded a deferred tax expense of 8.8 million for the year ended
December 31, 2015 and a deferred tax expense of 6.5 million for the year ended December 31, 2014. Deferred tax is charged for the annual movements in temporary differences between the carrying amounts of assets and liabilities
for financial reporting purposes and the amounts used for taxation purposes.

Revenue increased to 340.6 million for the year ended December 31, 2014 from
307.1 million for the year ended December 31, 2013, an increase of 11%. Recurring revenue increased by 10% and non-recurring revenue increased by 35% from the year ended December 31, 2013 to the year ended December 31,
2014. The period over period growth in recurring revenue was primarily the result of an increase of approximately 11,300 square meters in Revenue Generating Space as a result of sales to both existing and new customers in all of our regions.

Cost of Sales

Cost of sales increased to
139.1 million for the year ended December 31, 2014 from 124.1 million for the year ended December 31, 2013, an increase of 12%. Cost of sales was 41% of revenue for the year ended December 31, 2014 and 40% for
the year ended December 31, 2013. The increase in cost of sales was due to increased costs associated with our overall revenue growth and data center expansion projects, including (i) an increase of 5.1 million in energy usage
costs and (ii) an increase of 4.9 million in installation costs. Equipped Space increased by approximately 13,400 square meters during the year ended December 31, 2014 as a result of expansions to existing data centers in
London, Brussels, Stockholm and Zurich, the construction of new data centers in Frankfurt, Amsterdam, Vienna and Stockholm and the acquisition of a data center in Marseille. We expect cost of sales as a percentage of revenue to decrease as we
increase utilization at our existing facilities. This decrease may be offset by the impact of lower utilization in new data centers we open as part of our data center expansion projects.

Other Income

Other income represents
income that we do not consider part of our core business. It includes income from the subleases on unused data center sites.

Sales and Marketing Costs

Our sales and marketing costs increased to 24.6 million for the year ended December 31, 2014 from
22.8 million for the year ended December 31, 2013, an increase of 8%. Sales and marketing costs were 7% of revenue for each of the years ended December 31, 2014 and 2013.

The increase in sales and marketing costs was primarily a result of an increase of 1.2 million in compensation and related costs
due to increases in employee headcount and marketing expenses associated with our continued strategy to invest in our industry focused customer development and acquisition approach.

General and Administrative Costs

General
and administrative costs consist of depreciation, amortization and impairments, share-based payments, increase/(decrease) in provision for onerous lease contracts and other general and administrative costs.

Depreciation, amortization and impairments increased to 62.2 million for the year ended December 31, 2014 from
57.7 million for the year ended December 31, 2013, an increase of 8%. Depreciation, amortization and impairments was 18% of revenue for the year ended December 31, 2014 and 19% for the year ended December 31, 2013. The
increase was a result of new data centers and data center expansions, partly offset by lower depreciation charges attributable to a change in the estimated useful life of certain assets. In the fourth quarter of the year ended December 31, 2013, the
Company completed its annual review of the estimated useful life of its property, plant and equipment. As a result of this review, the Company concluded that certain of its existing assets were in use longer than originally anticipated. Therefore,
the estimated useful life of certain of our property, plant and equipment was extended effective October 1, 2013. On an annualized basis for the year 2013, the depreciation charges on a like for like basis would have been approximately 8
million lower.

In determining Adjusted EBITDA we add back share-based payments. For the year ended December 31, 2014 we recorded
share-based payments of 6.6 million, an increase of 58% from the year ended December 31, 2013. The increase is primarily due to new grants of options, restricted shares and performance shares in 2014. In determining Adjusted EBITDA
we also add back increase/(decrease) in provision for onerous lease contracts. Following our annual review of the provision for onerous lease contracts, the Company decreased the provision by 0.8 million in 2014 while in 2013, the provision
remained unchanged.

Other general and administrative costs increased to 30.6 million for the year ended
December 31, 2014 from 28.3 million for the year ended December 31, 2013, an increase of 8%. Other general and administrative costs were 9% of revenue for the years ended December 31, 2014 and December 31, 2013. The
increase in the other general and administrative costs was due to both an increase of 1.5 million in compensation costs principally resulting from an increase in salaries associated with an increased headcount and higher external hires
and to an increase in the costs for professional advisory services.

Net Finance Expense

Net finance expense decreased to 27.9 million for the year ended December 31, 2014 from 57.5 million for the year
ended December 31, 2013, a decrease of 51%. Net finance expense was 8% of revenue for the year ended December 31, 2014 and 19% of revenue for the year ended December 31, 2013. The decrease in net finance expense for the year ended
December 31, 2014 was due primarily to 31.0 million in costs incurred in 2013 related to the refinancing of our debt and higher capitalization of borrowing costs, partly offset by higher interest charges following the issue of 150.0
million Additional Notes in April 2014. We capitalized 3.6 million of borrowing costs during the period of construction of new data center space in the year ended December 31, 2014 compared to 1.7 million in the year ended
December 31, 2013.

Income Taxes

Income tax expense was 15.4 million for the year ended December 31, 2014 compared to 6.1 million for the year ended
December 31, 2013. Income tax expense was 5% of revenue for the year ended December 31, 2014 and 2% of revenue for the year ended December 31, 2013. The increase in income tax expenses was primarily due to an increase in profit before
tax in 2014 as a result of the one-time 31.0 million debt refinancing costs incurred in 2013, resulting in a 7.8 million negative tax impact in the year ended December 31, 2014. The effective income tax rate of 31% in the
year ended December 31, 2014, compared to 47% for the year ended December 31, 2013, was positively impacted by the tax effect, on the 31.0 million refinancing costs, included in the 2013 tax charge as a credit but at a lower than average
tax rate.

We recorded current tax expenses of 8.9 million for the year ended December 31, 2014 and 7.9 million
for the year ended December 31, 2013. We recorded deferred tax expense of 6.5 million for the year ended December 31, 2014 and deferred tax income of 1.8 million for the year ended December 31, 2013. Deferred tax
is charged for the annual movements in temporary differences between the carrying amounts of assets and liabilities for financial reporting purposes and the amounts used for taxation purposes.

The deferred tax income in the year ended December 31, 2013 was principally due to the pre-tax refinancing costs of 31.0 million,
which created a taxable loss.

Liquidity and Capital Resources

As of December 31, 2015 our total indebtedness consisted of (i) 475.0 million 6.00% Senior Secured Notes due 2020,
(ii) other debt and finance lease obligations totaling 36.2 million and (iii) mortgages totaling 44.6 million. The borrowing requirements of the Company are not subject to significant seasonality. Under our Revolving
Facility, interest is based on a floating rate index. The interest expense on the remainder of our outstanding indebtedness is based on a fixed rate, except for our mortgages. Our PAR3, PAR5, BRU1, AMS3, AMS6 and FRA8/FRA10 mortgages are subject to
a floating interest rate of EURIBOR plus an individual margin ranging from 200 to 275 basis points. The interest rates on the mortgages secured by our PAR3 and PAR5 properties have been swapped to a fixed rate for approximately 75% of the principal
outstanding amounts for a period of 10 years.

As of December 31, 2015 the interest payable under the Revolving Facility on (i) any EUR
amounts drawn would be at the rate of EURIBOR plus 350 basis points per annum, (ii) any Danish Kroner amounts drawn would be at the rate of CIBOR plus 350 basis points per annum, (iii) any Swedish Krona amounts drawn would be at the rate of STIBOR
plus 350 basis points per annum and (iv) other applicable currencies including GBP amounts drawn at the rate of LIBOR plus 350 basis points per annum. The Revolving Facility was undrawn as of December 31, 2015.

Historically, we have made significant investments in our property, plant and equipment and intangible assets in order to expand our data
center footprint and total Equipped Space as we have grown our business. In the year ended December 31, 2015 we invested 192.6 million in property, plant and equipment ( 186.1 million) and intangible assets ( 6.5 million), of which
175.7 million was attributed to expansion capital expenditures and the remainder was attributed to maintenance and other capital expenditures. In the year ended December 31, 2014 we invested 216.3 million in property, plant and
equipment (213.0 million) and intangible assets (3.3 million), of which 198.7 million, including acquisition of MRS1 data center (8 million), was attributed to expansion capital expenditures and the remainder was attributed
to maintenance and other capital expenditures. In the year ended December 31, 2013 we invested 143.4 million in property, plant and equipment (140.3 million) and intangible assets (3.1 million), of which
135.1 million, including acquisition of AMS3 data center (8.8 million), was attributed to expansion capital expenditures and the remainder was attributed to maintenance and other capital expenditures. Although in any one year the
amount of maintenance and replacement capital expenditures may vary, we expect that long-term such expenses will be between 4% and 6% of total revenue.

##### Table of Contents

As of December 31, 2015 we had 58.6 million of cash and cash equivalents of which
4.9 million was restricted cash, mostly denominated in euro. Restricted cash is held as collateral to support the issuance of bank guarantees on behalf of a number of subsidiary companies.

A limited amount of the Companys total cash balance may be subject to certain restrictions in select countries that cannot be
repatriated without a tax implication. The amount of cash that cannot be repatriated without a tax implication is negligible to the total liquidity of our business.

As of December 31, 2015 our 100.0 million Revolving Facility remained undrawn.

Net cash flows from/(used in) operating activities

The increase in net cash flows from operating activities in the year ended December 31, 2015 compared to the year ended December 31,
2014 was primarily due to our improved operating performance. The increase in net cash flows from operating activities in the year ended December 31, 2014 compared to the year ended December 31, 2013 was primarily due to our improved
operating performance and improved net working capital movements.

Net cash flows from/(used in) investing activities

The decrease in net cash flows used in investing activities in the year ended December 31, 2015 compared to the year ended
December 31, 2014 was primarily due to lower investments in data center assets in 2015, partially offset by 3.1 million of cash proceeds from the sale of a financial asset. Capital expenditures in the year ended December 31, 2015
primarily related to the addition and expansion of data centers in Amsterdam, Marseille, Vienna, Frankfurt and Stockholm. The increase in net cash flows used in investing activities in the year ended December 31, 2014 compared to the year ended
December 31, 2013 was primarily due to increased capital expenditures in the expansion of existing data centers in London, Brussels, Stockholm and Zurich, the construction of new data centers in Frankfurt, Amsterdam, Vienna and Stockholm and
the acquisition of a data center in Marseille.

Net cash flows from/(used in) financing activities

Net cash flows from financing activities during the year ended December 31, 2015 were principally the result of the 14.9 million
proceeds from the new mortgage on our FRA8 and FRA10 data centers, which we drew in December 2015 and 5.7 million proceeds from the exercises of stock options under our Equity based incentive plan. This was partially offset by repayments on
mortgages in The Netherlands, France and Belgium. Net cash flows from financing activities during the year ended December 31, 2014 were principally the result of 157.9 million in net proceeds from the offering of the Additional Notes due
2020 and 9.2 million in gross proceeds drawn under the new mortgage on our BRU1 property. Net cash flows from financing activities during the year ended December 31, 2013 were principally the result of 317.1 million in net proceeds
from the offering of the Senior Secured Notes due 2020 and the repayment of the 260.0 million Senior Secured Notes due 2017, 16.0 million in gross proceeds drawn under our new mortgage financings on our PAR3, PAR5 and AMS3 data
center properties and 4.5 million in gross proceeds that we received from share options exercised by management and employees.

##### Table of Contents

We anticipate that cash flows from operating activities and available credit from our Revolving
Facility will be sufficient to meet our operating requirements on a short-term (twelve months) and long-term basis, including repayment of the current portion as of December 31, 2015 of our debt as it becomes due, and to complete our publicly
announced expansion projects.

The Company assesses its capital raising and refinancing needs on an ongoing basis and may enter into
additional credit facilities and seek to issue equity and/or debt securities in the domestic and international capital markets if market conditions are favorable. Also, depending on market conditions, the Company may elect to repurchase portions of
its debt securities in the open market, pursuant to the redemption provisions in the applicable indenture or otherwise.

jurisdiction) on or after the date of the Indenture or, if the relevant taxing jurisdiction has changed since the date of the Indenture, on or after the date on which the then current relevant taxing jurisdiction became the relevant taxing
jurisdiction under the Indenture (each of the foregoing clauses (a) and (b), a Change in Tax Law).
| | --- | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

The Notes
also contain standard change of control provisions which require the Company to make an offer to each holder of Notes to purchase such holders Notes in cash equal to 101% of the principal amount thereof, plus accrued and unpaid interest, if
any, to the date of purchase, upon the occurrence of a change of control (as defined in the indenture for the Notes).

received by each Holder of the Notes (including Additional Amounts) after withholding or deduction on account of any such taxes from any payment made under or with respect to the Notes shall be not less than the amount that such Holder would have
received if such taxes had not been required to be withheld or deducted.

any Note on any redemption date, the greater of:



| | a) | 1.0% of the principal amount of the Note; and

interest payments that would otherwise be due to be paid on such Note during the period between the redemption date and July 15, 2016 (excluding accrued but unpaid interest), computed using a discount rate equal to the bund rate plus 50 basis
points; over

security trustee, provides for the 100.0 million Revolving Facility.

##### Table of Contents

Revolving Facility

Failure to comply with the financial covenants in our 100 million Revolving Facility Agreement would result in an event of default,
which may cause all amounts outstanding under the facility to become immediately due and payable. Acceleration of such outstanding amounts under the facility may lead to an event of default under the indenture governing our 475 million
6.00% Senior Secured Notes. Failure to satisfy the financial covenants in the indenture would result in our inability to incur additional debt under certain circumstances.

The Revolving Facility Agreement contains various covenants that restrict, among other things and subject to certain exceptions, the ability
of the Company and its subsidiaries to:



| |  |  | create certain liens;
| | - |  | ---------------------



| |  |  | incur debt and/or guarantees;
| | - |  | -----------------------------



| |  |  | enter into transactions other than on arms-length basis;
| | - |  | ---------------------------------------------------------



| |  |  | pay dividends or make certain distributions or payments;
| | - |  | --------------------------------------------------------



| |  |  | engage, in relation to the Company, in any business activity or own assets or incur liabilities not authorized by the Revolving Facility Agreement;
| | - |  | ---------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | sell certain kinds of assets;
| | - |  | -----------------------------



| |  |  | enter into any sale and leaseback transactions;
| | - |  | -----------------------------------------------



| |  |  | make certain investments or other types of restricted payments;
| | - |  | ---------------------------------------------------------------



| |  |  | substantially change the nature of the Company or the Groups business;
| | - |  | -----------------------------------------------------------------------



| |  |  | designate unrestricted subsidiaries; and
| | - |  | ----------------------------------------



| |  |  | effect mergers, consolidations or sale of assets.
| | - |  | -------------------------------------------------

The restrictive covenants are subject to
customary exceptions including, in relation to the incurrence of additional debt, a consolidated fixed charge ratio (calculated as a ratio of adjusted EBITDA to consolidated interest expense) to exceed 2.00 to 1.00 on a pro forma basis for the four
full fiscal quarters (taken as one period) for which financial statements are available immediately preceding the incurrence of such debt and, if such debt is senior debt, a consolidated senior leverage ratio (calculated as a ratio of outstanding
senior debt of the Company and its restricted subsidiaries (on a consolidated basis) to pro forma adjusted EBITDA) to be less than 4.00 to 1.00 on a pro forma basis for the four full fiscal quarters (taken as one period) for which financial
statements are available immediately preceding the incurrence of such debt. The Revolving Facility Agreement also includes a leverage ratio financial covenant (tested on a quarterly basis) requiring total net debt (calculated as a ratio to pro forma
EBITDA) not to exceed 4.00 to 1.00. In addition, the Company must ensure that the guarantors represent a certain percentage of adjusted EBITDA of the Group as a whole and a certain percentage of the consolidated net assets of the Group as a whole.

The breach of any of these covenants by the Company or the failure by the Company to maintain its leverage ratio could result in a
default under the Revolving Facility Agreement. As of December 31, 2015, the Company was in compliance with all covenants in the Revolving Facility Agreement. In addition, the Company does not anticipate any such breach or failure and believes that
its ability to borrow funds under the Revolving Facility Agreement will not be adversely affected by the covenants in the next twelve months.

Senior Secured Notes Indenture

The Indenture contains covenants for the benefit of the holders of the Notes that restrict, among other things and subject to certain
exceptions, the ability of the Company and its subsidiaries to:



| |  |  | incur debt;
| | - |  | -----------



| |  |  | enter into certain transactions with, or for the benefit of, an affiliate;
| | - |  | --------------------------------------------------------------------------



| |  |  | create or incur certain liens;
| | - |  | ------------------------------



| |  |  | incur a change in control;
| | - |  | --------------------------



| |  |  | pay dividends or make certain distributions or payments;
| | - |  | --------------------------------------------------------

EBITDA and Adjusted EBITDA

EBITDA for the years ended December 31, 2015, December 31, 2014 and December 31, 2013 was 173.7 million, 140.6
million and 128.0 million, respectively, representing 45%, 41% and 42% of revenue, respectively. Adjusted EBITDA for the years ended December 31, 2015, December 31, 2014 and December 31, 2013 was 171.3 million, 146.4
million and 131.8 million respectively, representing 44%, 43% and 43% of revenue, respectively.

We define EBITDA as operating
profit plus depreciation, amortization and impairment of assets. We define Adjusted EBITDA as EBITDA adjusted to exclude share-based payments, M&A transaction costs, increase/decrease in provision for onerous lease contracts, M&A transaction
break fee income, and income from sub-leases of unused data center sites. Adjusted EBITDA margin is defined as Adjusted EBITDA as a percentage of revenue. We present EBITDA, Adjusted EBITDA and Adjusted EBITDA margin as additional information
because we understand that they are measures used by certain investors and because they are used in our financial covenants in our 100 million Revolving Facility Agreement and 475 million 6.00% Senior Secured Notes due 2020.
However, other companies may present EBITDA, Adjusted EBITDA and Adjusted EBITDA margin differently than we do. EBITDA, Adjusted EBITDA and Adjusted EBITDA margin are not measures of financial performance under IFRS and should not be considered as
an alternative to operating profit or as a measure of liquidity or an alternative to net income as indicators of our operating performance or any other measure of performance derived in accordance with IFRS.

The following table presents a reconciliation of EBITDA and Adjusted EBITDA to operating profit according to our income statement, for the
periods indicated:

|(2) | Capital (finance) lease obligations include future interest payments.
|--- | ---------------------------------------------------------------------

|(3) | Operating lease obligations include the lease of property and equipment. Of our total operating leases, as of December 31, 2015, an amount of 70.6 million is cancellable until January 1, 2016.

We entered into 18 irrevocable bank guarantees totaling 6.0 million with ABN AMRO Bank, Royal Bank of Scotland,
La Caixa and Frankfurter Sparkasse. These bank guarantees were primarily provided in lieu of cash deposits for lease contracts and either automatically renew in successive one-year periods or remain in effect, in each case, until the final lease
expiration date. The bank guarantees are cash collateralized and the collateral is reflected as restricted cash on our statement of financial position. These contingent commitments are not reflected in the table above.

Primarily as a result of our various data center expansion projects, as of December 31, 2015, we were contractually committed for
66.2 million of unaccrued capital expenditures, primarily for data center equipment not yet delivered and labor not yet provided, in connection with the work necessary to complete construction and open these data centers prior to making
them available to customers for installation. This amount, which is expected to be paid in 2016, is reflected in the table above as Capital purchase commitments.

We have other non-capital purchase commitments in place as of December 31, 2015, such as commitments to purchase power in select
locations, through the year 2016, and other open purchase orders, which contractually bind us for goods or services to be delivered or provided during the remainder of 2016 and beyond. Such other purchase commitments as of December 31, 2015,
which totaled 50.1 million, are also reflected in the table above as Other contractual purchase commitments.

In
addition, although we are not contractually obligated to do so, we expect to incur additional capital expenditures consistent with our disciplined expansion and conservative financial management in our various data center expansion projects during
the remainder of 2016 in order to complete the work needed to open these data centers. These non-contractual capital expenditures are not reflected in the table above.

On January 18, 2013, the Group entered into a 10 million mortgage financing. The mortgage loans are secured by mortgages on the PAR3
land owned by Interxion Real Estate II Sarl and the PAR5 land owned by Interxion Real Estate III Sarl, a pledge on the rights under the intergroup lease agreements between Interxion Real Estate II Sarl and Interxion Real Estate III Sarl, as lessors,
and Interxion France SAS, as lessee, and are guaranteed by Interxion France SAS. The repayment of principal under the mortgage loans are required to be repaid in quarterly installments collectively amounting to 167,000 commencing April 18,
2013. The mortgage loans have a maturity of fifteen years and a variable interest rate based on EURIBOR plus an individual margin ranging from 240 to 280 basis points. The mortgage loan agreements require the interest rate to be fixed for a minimum
of 40% of the principal outstanding amount for a minimum of six years. In April 2013, the interest rate was fixed for approximately 75% of the principal outstanding amount for a period of 10 years.

On June 26, 2013, the Group entered into a 6 million mortgage financing. The mortgage loan
is secured by a mortgage on the AMS3 property owned by Interxion Real Estate V B.V. and a pledge on the rights under the intergroup lease agreement between Interxion Real Estate V B.V., as lessor, and Interxion Nederland B.V., as lessee. The
repayment of principal under this mortgage loan is required to be repaid in annual installments of 400,000 commencing May 1, 2014 and a final repayment of 4,400,000 due on May 1, 2018. The mortgage loan agreement includes a variable
interest rate based on EURIBOR plus 275 basis points. The mortgage loan contains a minimum debt service capacity ratio of 1:1 based on the operations of Interxion Real Estate V B.V.

On April 1, 2014, the Group completed a 9.2 million mortgage financing with respect to our data center in Belgium. The facility is
guaranteed by Interxion Real Estate Holding B.V. and is secured by a (i) mortgage on the data center property in Belgium, which was acquired by Interxion Real Estate IX N.V. on January 9, 2014 and (ii) pledge over the lease agreement. The facility
has a maturity of fifteen years and has a variable interest rate based on EURIBOR plus 200 basis points. The principal amount is to be repaid in 59 quarterly installments of 153,330 of which the first quarterly installment was paid on July 31,
2014 and a final repayment of 153,330 is due on April 30, 2029. This mortgage does not contain any financial maintenance covenants.

On October 13, 2015, the Group completed a 15.0 million mortgage financing with respect to certain property in Germany. The facility is
secured by a mortgage on the real estate property (FRA8 and FRA10) in Germany, which is owned by Interxion Real Estate I B.V., and a pledge over the lease agreement. The facility has a maturity of five years and has a variable interest rate based on
EURIBOR plus 225 basis points. The principal amount is to be repaid in four annual installments of 1,000,000 of which the first quarterly installment is due on September 30, 2016, and a final repayment of 11,000,000 which is due on
September 30, 2020.

On September 29, 2015, the Group entered into a contract to lease the properties related to the AMS8 data center. The
lease, which covers land and building, will commence during the second quarter of 2016. The land component will be treated as an operating lease, the building as a financial lease and the fair value of the leased assets is estimated to be 26.2
million.

Critical Accounting Estimates

Basis of Measurement

We present our
financial statements in thousands of euro. They are prepared under the historical cost convention except for certain financial instruments. The financial statements are presented on the going-concern basis. Our functional currency is the euro.

The accounting policies set out below have been applied consistently by us and our wholly-owned subsidiaries and to all periods presented in
these consolidated financial statements.

Use of Estimates and Judgments

The preparation of financial statements in conformity with IFRS requires management to make judgments, estimates and assumptions that affect
the application of accounting policies and the reported amounts of assets, liabilities, income and expenses. Actual results may differ from these estimates. Estimates and underlying assumptions are reviewed on an ongoing basis. Revisions to
accounting estimates are recognized in the period in which the estimates are revised and in any future periods affected.

Judgments,
estimates and assumptions applied by management in preparing the financial statements are based on circumstances as of December 31, 2015 and based on Interxion operating as a stand-alone company.

In particular, information about significant areas of estimation uncertainty and critical judgments in applying accounting policies that have
the most significant effect on amounts recognized in the financial statements are discussed below.

Property, Plant and Equipment Depreciation

Estimated remaining useful lives and residual values are reviewed annually. The carrying values of property, plant and equipment are also
reviewed for impairment where there has been a triggering event by assessing the present value of estimated future cash flows and net realizable value compared with net book value. The calculation of estimated future cash flows and residual values
is based on our best estimates of future prices, output and costs and is therefore subjective. Furthermore, the valuation of some of the assets under construction requires judgments which are related to the probability of signing lease contracts and
obtaining planning permits.

In the fourth quarter of 2013, as part of the annual review of the estimated useful lives, we concluded that
certain of our existing assets are used longer than originally anticipated. The estimated useful lives of certain of our property, plant and equipment have, therefore, been extended. This change was accounted for as a change in accounting estimate
on a prospective basis effective October 1, 2013 under IAS 8 Change in Accounting Estimates. In the fourth quarter of 2013, depreciation expenses were approximately 2.0 million less than the prior quarter as a result of changes in
the estimated useful lives of certain of our property, plant and equipment. On an annualized basis for the year ended December 31, 2013, depreciation charges would have been approximately 8.0 million lower.

Intangible Fixed Assets Amortization

Estimated
remaining useful lives and residual values are reviewed annually. The carrying values of intangible fixed assets are also reviewed for impairment where there has been a triggering event by assessing the present value of estimated future cash flows
and net realizable value compared with net book value. The calculation of estimated future cash flows and residual values is based on our best estimates of future prices, output and costs and is therefore subjective.

Lease Accounting

At inception or modification
of an arrangement, the Group determines whether such an arrangement is or contains a lease. Classification of a lease contract (operating versus a finance lease) is based on the extent to which risks and rewards incidental to ownership of a leased
asset lie with the lessor or the lessee. The classification of lease contracts includes the use of judgments and estimates.

Costs of Site Restoration

Liabilities in respect of obligations to restore premises to their original condition are estimated at the commencement of the lease and
reviewed yearly based on rents, remaining terms, contracted extension possibilities and possibilities of lease terminations. A provision for site restoration is recognized when costs for restoring leasehold premises to their original condition at
the end of the lease term is required to be made and the likelihood of this liability is estimated to be probable. The discounted cost of the liability is included in the related assets and is depreciated over the remaining estimated term of the
lease. If the likelihood of this liability is estimated to be possible, rather than probable, it is disclosed as a contingent liability.

Provision for
Onerous Lease Contracts

Provision is made for the discounted amount of future losses expected to be incurred in respect of unused data
center sites over the term of the leases. Where unused sites have been sublet or partly sublet, management has taken account of the contracted rental income to be received over the minimum sublease term in arriving at the amount of future losses.
Currently, the provision for onerous lease contracts principally relates to two unused data center sites in Germany, one in Munich which was terminated in March 2016and one in Dusseldorf terminating in August 2016.

Deferred Taxation

Provision is made for
deferred taxation at the rates of tax prevailing at the period end dates unless future rates have been substantively enacted. Deferred tax assets are recognized where it is probable that they will be recovered based on estimates of future taxable
profits for each tax jurisdiction. The actual profitability may be different depending upon local financial performance in each tax jurisdiction.

Share-based Payments

Equity-settled share-based
payments are issued to certain employees under the terms of the long term incentive plans. The charges related to equity-settled share-based payments, options to purchase ordinary shares, are measured at fair value at the date of grant. The fair
value at the grant date is determined using the Black Scholes model and is expensed over the vesting period. The value of the expense is dependent upon certain assumptions including the expected future volatility of the Companys share price at
the date of the grant.

Senior Secured Notes due 2020

The Senior Secured Notes due 2020 are valued at amortized costs. The Senior Secured Notes due 2020 indenture includes optional redemption
provisions, which allow us to redeem the Notes prior to their stated maturity. As part of the initial measurement of the amortized cost value of the Senior Secured Notes due 2020, we have assumed that the Notes will be held to maturity. If we redeem
all or part of the Notes prior to their stated maturity the liability will be re-measured based on the original effective interest rate. The difference between the liability of excluding a change in assumed early redemption and the liability
compared to including a change in assumed early redemption, will be reflected in our profit and loss.

Recent Accounting Pronouncements

The new standards, amendments to standards and interpretations listed below are available for early adoption in the annual period beginning
January 1, 2015, although they are not mandatory until a later period. The Group has decided not to adopt these new standards or interpretations until a later point in time.

Board
Powers and Function

Our Board is responsible for the overall conduct of our business and has the powers, authorities and duties vested
in it by and pursuant to the relevant laws of The Netherlands and our articles of association. In all its dealings, our Board shall be guided by the interests of our Group as a whole, including but not limited to our shareholders. Our Board has the
final responsibility for the management, direction and performance of us and our Group. Our Executive Director will be responsible for the day-to-day management of the Company. Our Non-Executive Directors will supervise the Executive Director and
our general affairs and provide general advice to the Executive Director.

Our CEO is the general manager of our business, subject to the
control of our Board, and is entrusted with all of our Boards powers, authorities and discretions (including the power to sub-delegate) delegated by the full Board from time to time by a resolution of our Board. Matters expressly delegated to
our CEO are validly resolved upon by our CEO and no further resolutions, approvals or other involvement of our Board is required. Our Board may also delegate authorities to its committees. Upon any such delegation our Board supervises the execution
of its responsibilities by our CEO and/or our Board committees. It remains ultimately responsible for the fulfillment of its duties by them.

Our articles of association provide that in the event we have a conflict of interest with one or more Directors, we may still be represented
by the Board or an Executive Director. In the event of a conflict of interest, however, our general meeting of shareholders has the power to designate one or more other persons to represent us. Our articles of association provide that in the event
we have a conflict of interest with one or more Directors, we may still be represented by the Board or an Executive Director. In the event of a conflict of interest, however, our general meeting of shareholders has the power to designate one or more
other persons to represent us. Under Dutch law, a Director is prohibited from participating in any Board discussion or decision making pertaining to a subject in which such director has a conflict of interest.

Board Meetings and Decisions

All
resolutions of our Board are adopted by an absolute majority of votes cast in a meeting at which at least the majority of the Directors are present or represented. A member of the Board may authorize another member of the Board to represent him/her
at the Board meeting and vote on his/her behalf. Each Director is entitled to one vote (provided that, for the avoidance of doubt, a member representing one or more absent members of the Board by written power of attorney will be entitled to cast
the vote of each such absent member). If there is a tie, the Chairman has the casting vote.

Our Board meets as often as it deems
necessary or appropriate or upon the request of any member of our Board. Our Board has adopted rules, which contain additional requirements for our decision-making process, the convening of meetings and, through separate resolution by our Board,
details on the assignment of duties and a division of responsibilities between Executive Directors and Non-Executive Directors. Our Board has appointed one of the Directors as Chairman and one of more Directors as Vice-Chairman of the Board. Our
Board is further assisted by a corporate secretary. The corporate secretary may be a member of our Board or our Senior Management and is appointed by our Board.

Composition of Board

The majority of our
Directors are independent as required by the NYSE.

##### Table of Contents

Our Board consists of a minimum of one Executive Director and a minimum of three Non-Executive
Directors, provided that our Board is comprised of a maximum of 7 (seven) members. The number of Executive Directors and Non-Executive Directors is determined by our general meeting of shareholders, provided that the majority of our Board must
consist of Non-Executive Directors. Only natural persons can be Non-Executive Directors. The Executive Directors and Non-Executive Directors as such are appointed by our general meeting of shareholders, provided that our Board is classified, with
respect to the term for which each member of our Board will severally be appointed and serve as member of our Board, into three classes, as nearly equal in number as reasonably possible.

The class I Directors serve for a term expiring at the annual general meeting of shareholders in 2017, the class II Directors serve for a term
expiring at the annual general meeting of shareholders in 2018 and the class III Directors serve for a term expiring at the annual general meeting of shareholders in 2016. At each annual general meeting of shareholders, Directors appointed to
succeed those Directors whose terms expire are appointed to serve for a term of office to expire at the third succeeding annual general meeting of shareholders after their appointment. Notwithstanding the foregoing, the Directors appointed to each
class continue to serve their term in office until their successors are duly appointed and qualified or until their earlier resignation, death or removal. If a vacancy occurs, any Director so appointed to fill that vacancy serves its term in office
for the remainder of the full term of the class of Directors in which the vacancy occurred.

Our Board has nomination rights with respect
to the appointment of a Director. Any nomination by our Board may consist of one or more candidates per vacant seat. If a nomination consists of a list of two or more candidates, it is binding and the appointment to the vacant seat concerned will be
from the persons placed on the binding list of candidates and will be effected through election. Notwithstanding the foregoing, our general meeting of shareholders may, at all times, by a resolution passed with a two-thirds majority of the votes
cast representing more than half of our issued and outstanding capital, resolve that such list of candidates will not be binding.

Directors may be suspended or removed at any time by our general meeting of shareholders. A resolution to suspend or remove a Director must be
adopted by at least a two-thirds majority of the votes cast, provided such majority represents more than half of our issued and outstanding share capital. Executive Directors may also be suspended by the Board.

Directors Insurance and Indemnification

In order to attract and retain qualified and talented persons to serve as members of our Board or our Senior Management, we currently do and
expect to continue to provide such persons with protection through a directors and officers insurance policy. Under this policy, any of our past, present or future Directors and members of our Senior Management will be insured against
any claim made against any one of them for any wrongful act in their respective capacities.

Under our articles of association, we are
required to indemnify each current and former member of our Board who was or is involved, in that capacity, as a party to any actions or proceedings, against all conceivable financial loss or harm suffered in connection with those actions or
proceedings, unless it is ultimately determined by a court having jurisdiction that the damage was caused by intent (opzet), willful recklessness (bewuste roekeloosheid) or serious culpability (ernstige verwijtbaarheid) on the
part of such member.

Insofar as indemnification of liabilities arising under the Securities Act may be permitted to members of our Board,
officers or persons controlling us pursuant to the foregoing provisions, we have been informed that, in the opinion of the SEC, such indemnification is against public policy as expressed in the Securities Act and is therefore unenforceable.

Board Committees

Our Board has
established an audit committee, a compensation committee and a nominating committee. The audit committee is in compliance with the NYSE listed company board committee independence requirements. The compensation committee and the nominating committee
currently meet the NYSE independence standard. However, in the past, including during the year ended December 31, 2015, our compensation committee and nominating committee did not meet the NYSE independence standard. Rule 303A permits foreign
private issuers like us to follow home country practice with regard to, amongst others, the independence requirement for the compensation committee and for the nominating committee. Our Board may also establish such other committees as it deems
appropriate, in accordance with applicable law and regulations and our articles of association and any applicable Board rules.

##### Table of Contents

Many of the NYSE corporate governance rules do not apply to us as a foreign private
issuer; however, Rule 303A.11 requires foreign private issuers to describe significant differences between their corporate governance standards and the corporate governance standards applicable to U.S. companies listed on the NYSE. While we
believe that our corporate governance practices are similar in many respects to those of U.S. NYSE-listed companies and provide investors with protections that are comparable in many respects to those established by the NYSE rules, there have been
certain key differences which are described below.

Audit Committee

Our audit committee consists of three independent Directors, Rob Ruijter, Frank Esser and Mark Heraghty, with Rob Ruijter serving as the
chairperson of the audit committee. The audit committee is independent as defined under and required by Rule 10A-3 under the U.S. Securities Exchange Act of 1934, as amended (Rule 10A-3) and the NYSE. Our Board of Directors has
determined that Rob Ruijter qualifies as an audit committee financial expert, as that term is defined in Item 16A of Form 20-F. The audit committee has the responsibility, subject to Board and shareholder approval, for the
appointment, compensation, retention and oversight of the work of our independent registered public accounting firm, KPMG Accountants N.V. In addition, approval of the audit committee is required prior to our entering into any related-party
transaction. It is also responsible for whistle-blowing procedures, certain other compliance matters and the evaluation of the Companys policies with respect to risk assessment and risk management.

Compensation Committee

Our
compensation committee consists of three independent Directors, Rob Ruijter, Frank Esser and Mark Heraghty. Until June 5, 2015, John Baker, a former non-independent Director, served as the chairperson of the compensation committee. Since June 8,
Mark Heraghty has acted as the chairperson of the compensation committee. Among other things, the compensation committee reviews, and makes recommendations to the Board regarding, the compensation and benefits of our CEO and our Board. The
compensation committee also administers the issuance of stock options and other awards under our equity incentive plan and evaluates and reviews policies relating to the compensation and benefits of our employees and consultants.

Under Section 303A.05 of the NYSE rules, which govern compensation committees, the Companys compensation committee meets the NYSE
independence standard. However, prior to June 5, 2015, the Companys compensation committee included one member that was not independent as defined under the applicable NYSE rules.

Nominating Committee

Our
nominating committee consists of three independent Directors, Jean Mandeville, Frank Esser and Mark Heraghty. Until June 5, 2015, John Baker, a former non-independent Director, served as the chairperson of the nominating committee. Since June 8,
Frank Esser has acted as the chairperson of the nominating committee. The nominating committee is responsible for, among other things, developing and recommending to our Board our corporate governance guidelines, identifying individuals qualified to
become Directors, overseeing the evaluation of the performance of the Board, selecting the Director nominees for the next annual meeting of shareholders, and selecting director candidates to fill any vacancies on the Board.

Under Section 303A.04 of the NYSE rules, which govern nominating/corporate governance committees, the Companys nominating committee
meets the NYSE independence standard. However, prior to June 5, 2015, the Companys nominating committee included one member that was not independent as defined under the applicable NYSE rules.

Compensation

The aggregate annual
compensation of our Senior Management and Non-Executive Directors for the year ended December 31, 2015 was approximately 7.2 million.

Employee Share
Ownership Plans

On May 24, 2013, pursuant to the recommendation of our compensation committee, our Board adopted the 2013
International Equity Based Incentive Plan (the 2013 Plan). The 2013 Plan was implemented to replace the InterXion Holding N.V. 2011 International Stock Option Plan and Incentive Master Award Plan (the 2011 Plan). Pursuant to
further recommendation of our compensation committee, our Board amended the 2013 Plan and adopted the 2013 Amended International Equity Based Incentive Plan (the 2013 Amended Plan) on October 30, 2013. The 2013 Amended Plan was further
amended on March 17, 2014 by our Board, pursuant to the recommendation of our compensation committee to clarify that the 2013 Amended Plan was adopted by the Board of Directors, instead of just by the Compensation Committee. The 2013 Amended Plan
provides the compensation committee with the authority to award options, performance shares and restricted shares to certain employees and advisors.

We implemented the 2013 Amended Plan to attract and retain certain employees, advisors and board members and reward them for their
contributions to the Group. The 2013 Amended Plan is designed to act as an incentive scheme, whereby various equity-based instruments may be awarded from time-to-time in accordance with the terms and conditions of the 2013 Amended Plan. The 2013
Plan was discontinued following the implementation of the 2013 Amended Plan, however, outstanding options will continue to be governed by the terms of the 2013 Plan until such options have been exercised in full.

The total number of shares which may be granted pursuant to the 2013 Amended Plan is 5,273,371 shares (the Share Pool). The Share
Pool includes grants made under the 2011 Plan, the 2013 Plan and the 2013 Amended Plan. Shares subject to awards that expire, terminate or are otherwise surrendered, canceled or forfeited under the 2011 Plan, the 2013 Plan or the 2013 Amended Plan
are returned to the Share Pool. Taking into account the grants made under those plans, as of December 31, 2015, approximately 2.1 million shares are available for grant.



Notes:

|(1) | The compensation for the Senior Management team (excluding D.C. Ruberg) includes the compensation for J. Joshi, J. Camman, J.P. Anten and G. Di Vitantonio.

##### Table of Contents

Under the 2011 Plan, our Board could grant options for ordinary shares to certain eligible
persons following completion of our initial public offering. The 2011 Plan was discontinued following the implementation of the 2013 Plan.

Our 2008 International Stock Option Plan and Incentive Master Award Plan (the 2008 Plan) was discontinued following our initial
public offering. Outstanding options, however, will continue to be governed by the terms of the 2008 Plan until such options have been exercised in full.

Corporate Governance

The Dutch Corporate
Governance Code, as revised, became effective on January 1, 2009, and applies to all Dutch companies listed on a government-recognized stock exchange, whether in The Netherlands or elsewhere. The Dutch Corporate Governance Code is based on a
comply or explain principle, under which all companies filing annual reports in The Netherlands must disclose whether or not they are in compliance with the various rules of the Dutch Corporate Governance Code and explain the reasons for
any instance of noncompliance.

With exception to Sections 303A.04 and 303A.05 of the NYSE rules, which govern nominating/corporate
governance committees and compensation committees, respectively, we intend to comply with the NYSE rules. We also intend to comply with the Dutch Corporate Governance Code, but where the NYSE rules conflict with the Dutch Corporate Governance Code
we intend to comply with the NYSE rules. For further information with respect to the composition of our Board committees, see the discussed above under Board Committees.

Stock Options, Restricted and Performance Shares

As of March 16, 2016 our directors and senior managers were granted the awards (options, restricted and performance shares outstanding) as set
forth below. The awards with exercise prices denominated in $ are awards granted under the 2011 Plan, the 2013 Plan and the Amended 2013 Plan. The restricted shares have been granted under the 2013
Plan.

The ordinary shares beneficially owned by our directors and senior managers are disclosed in Item 7 Major
Shareholders and Related Party Transactions.

ITEM 7: MAJOR SHAREHOLDERS AND RELATED PARTY TRANSACTIONS

Major Shareholders

The
following table sets forth information with respect to Directors, Senior Management and major shareholders, meaning shareholders that are beneficial owners of 5% or more of our ordinary shares as of March 16 , 2016.

Beneficial ownership is determined in accordance with rules of the SEC and generally includes any shares over which a person exercises sole or
shared voting and/or investment power. Ordinary shares subject to options and warrants currently exercisable or exercisable within 60 days are deemed outstanding and have therefore been included in the number of shares owned and the calculation of
the percentage ownership of the person holding the options but are not deemed outstanding for computing the percentage ownership of any other person.

We effected a registered public offering of our ordinary shares and our ordinary shares began trading on the NYSE on January 28,
2011. Our major shareholders have the same voting rights as our other shareholders. As of March 16, 2016, we had 14 shareholders of record. Two of the shareholders of record were located in the United States and held in the aggregate 70,047,531
ordinary shares representing approximately 99.8% of our outstanding ordinary shares. However, the United States shareholders of record include Cede & Co., which, as nominee for The Depository Trust Company, is the record holder of
70,028,410 ordinary shares. Accordingly, we believe that the shares held by Cede & Co. include ordinary shares beneficially owned by both holders in the United States and non-United States beneficial owners. As a result, these numbers may
not accurately represent the number of beneficial owners in the United States.

Related Party Transactions

Share distribution by Baker Capital

On June 2, 2015, Lamont Finance N.V. and Baker Communications Fund II, L.P. requested that we instruct our Transfer Agent, American Stock
Transfer & Trust Company, to remove the restrictive legend on all of the 18,657,592 ordinary shares held by Lamont Finance N.V. and Baker Communications Fund II, L.P.

Baker Capital (Baker) made a pro rata distribution-in-kind of these shares immediately to the partners of Baker Communications
Fund II (Cayman) L.P. and Baker Communications Fund II L.P., which funds initially acquired Interxion shares in 2000. Under the terms of the undertaking executed by Baker in support of the proposed transaction between Interxion and TelecityGroup
plc, it was contemplated that Baker would make a full distribution of its shares to its partners upon the closing of the transaction. The distribution was made following the termination of the proposed transaction with TelecityGroup plc and the
related undertaking executed by Baker. Following the distribution, Baker owns shares constituting less than 1% of our outstanding ordinary shares.

This distribution did not have any effect upon the total number of ordinary shares outstanding.

As a result of the 18.6 million ordinary share distribution by funds affiliated with Baker, Mr. John Baker (on June 5, 2015) and Mr. Rob
Manning (on June 7, 2015), tendered their resignations as Directors, effective immediately. Mr. Jean F.H.P. Mandeville was appointed as the new Chairman of the Board replacing Mr. Baker, effective June 8, 2015. Pursuant to our Articles of
Association, the Board is comprised of at least one Executive Director and three Non-executive Directors. At most the Board shall be comprised of seven Directors, a majority of which shall be Non-executive Directors. Consequently the current
composition of the Board is compliant with the Companys Articles. The Company may decide to increase the number of Directors in accordance with its Articles.

On June 8, 2015, our Board adopted amendments to the Companys Bylaws to eliminate references to the shareholders agreement of February
2, 2011 between the Company and affiliates of Baker Capital, which is no longer in place, and to related provisions.

ITEM 8: FINANCIAL INFORMATION

Reference is made to Item 18 for a list of all financial statements filed as part of this annual report. For information on legal
proceedings, please refer to Item 4 Information on the Company, above.

Dividends and Dividend Policy

We have never declared or paid cash dividends on our ordinary shares. We currently intend to retain any future earnings to fund the development
and growth of our business and we do not currently anticipate paying dividends on our ordinary shares. Our Board of Directors will have the discretion to determine to what extent profits shall be retained by way of a reserve. The remaining profits
will be at the disposal of our general meeting of shareholders for distribution of a dividend or to be added to the reserves or for such other purposes as our general meeting of shareholders decides, upon a proposal of our Board of Directors. Our
Board of Directors, in determining whether to recommend to our shareholders the payment of dividends, will consider our ability to declare and pay dividends in light of our future operations and earnings, capital expenditure requirements, general
financial conditions, legal and contractual restrictions and other factors that it may deem relevant. In addition, our outstanding 475 million 6.00% Senior Secured Notes due 2020 and our credit agreements limit our ability to pay
dividends and we may in the future become subject to debt instruments or other agreements that further limit our ability to pay dividends. To the extent we pay dividends in euro, the amount of U.S. dollars realized by shareholders will vary
depending on the rate of exchange between U.S. dollars and euro. Shareholders will bear any costs related to the conversion of euro into U.S. dollars.

We are a holding company incorporated in The Netherlands. Under Dutch law, we may only pay dividends out of our profits or our share premium
account subject to our ability to service our debts as they fall due in the ordinary course of our business and subject to Dutch law and our articles of association. See Item 10 Additional InformationGeneral. We rely on
dividends paid to us by our wholly-owned subsidiaries in the United Kingdom, France, Germany, Austria, The Netherlands, Ireland, Spain, Sweden, Switzerland, Belgium and Denmark to fund the payment of dividends, if any, to our shareholders.

ITEM 10: ADDITIONAL INFORMATION

Material contracts

The Intercreditor Agreement dated as of July 3, 2013, among InterXion Holding N.V. and certain of its subsidiaries and Barclays Bank PLC
as security trustee.

The intercreditor agreement entered into in connection with the Revolving Facility Agreement and the
Indenture is referred to in this description as the Intercreditor Agreement and InterXion Holding N.V. and each of its subsidiaries that incurs any liability or provides any guarantee under the Revolving Facility Agreement or the
Indenture is referred to in this description as a Debtor and are referred to collectively as the Debtors.

In
connection with the Revolving Facility Agreement, InterXion Holding N.V. and certain of its subsidiaries entered into an English law governed intercreditor agreement governing the relationships and relative priorities among: (i) the Lenders (as
defined below); (ii) original hedge counterparty or other persons that accede to the intercreditor agreement as counterparties to certain hedging agreements (the Hedging Agreements; the original hedge counterparty and any other person
that accedes to the intercreditor agreement as counterparties to the Hedging Agreements are referred to in such capacity as the Hedge Counterparties); (iii) the holders of the Senior Secured Notes and (iv) intra-group creditors and
debtors. In addition, the intercreditor agreement regulates the relationship between InterXion Holding N.V. and its subsidiaries, on the one hand, and shareholders of InterXion Holding N.V. and related parties, on the other hand.

The Intercreditor Agreement, among other things, sets out:



| |  |  | the relative ranking of certain indebtedness of the Debtors (including under the Revolving Facility Agreement and the Senior Secured Notes);
| | - |  | --------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | the relative ranking of certain security granted by the Debtors;
| | - |  | ----------------------------------------------------------------



| |  |  | when payments can be made in respect of certain indebtedness of the Debtors (including the Revolving Facility Agreement and the Senior Secured Notes);
| | - |  | ------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | when enforcement actions can be taken in respect of that indebtedness and the distribution of any enforcement proceeds;
| | - |  | -----------------------------------------------------------------------------------------------------------------------



| |  |  | the terms pursuant to which that indebtedness will be subordinated upon the occurrence of certain insolvency events;
| | - |  | --------------------------------------------------------------------------------------------------------------------



| |  |  | turnover provisions; and
| | - |  | ------------------------



| |  |  | when security and guarantees will be released to permit a sale of the collateral.
| | - |  | ---------------------------------------------------------------------------------

The
Intercreditor Agreement allows for the issuance of senior unsecured notes by InterXion Holding N.V., and for such senior unsecured notes to be guaranteed by the Debtors on a subordinated basis, and includes customary provisions in relation to
issuance of the senior unsecured notes. By accepting a note, holders of the notes shall be deemed to have agreed to, and accepted the terms and conditions of, the Intercreditor Agreement.

The Revolving Facility Agreement dated as of June 17, 2013, among InterXion Holding N.V. and the financial institutions party thereto,
as Lenders and Barclays Bank PLC, as agent and security trustee.

On June 17, 2013, we entered into the English law governed
Revolving Facility Agreement between, among others, InterXion Holding N.V., the lenders named therein (the Lenders) and Barclays Bank PLC as agent (the Agent) and security trustee, pursuant to which a 100.0 million
revolving facility has been made available to the Company.

Borrowings under the Revolving Facility will be used to finance our general
corporate and working capital needs (including capital expenditure, acquisitions and investments, which are not prohibited by the Revolving Facility Agreement), but not the prepayment, repayment or redemption of bonds, term debt or replacement debt
(or any interest in any bonds, term debt or replacement debt) and the purchase of bonds, term debt or replacement debt in open market purchases or otherwise (as such terms are defined in the Revolving Facility Agreement).

The Revolving Facility initially bears interest at a rate per annum equal to EURIBOR (or, for loans denominated in Sterling, USD, DKK, SEK or
CHF, LIBOR, CIBOR or STIBOR (as applicable)) plus a margin of 3.50% per annum, subject to a margin ratchet pursuant to which the margin may be reduced by up to a maximum of 1.00% per annum if total net debt (as defined in the Revolving Facility
Agreement) at each quarter end to the pro forma EBITDA for the twelve months ending on that quarter end (as such terms are defined in the Revolving Facility Agreement) is equal to or less than 2.00:1.



73

##### Table of Contents

We are also required to pay a commitment fee, quarterly in arrears, on available but undrawn
commitments under the Revolving Facility at a rate of 40.0% of the then applicable margin.

The Revolving Facility Agreement has a final
maturity date of July 3, 2018. Any amount still outstanding at that time will be immediately due and payable. Subject to certain conditions, any borrower under the Revolving Facility Agreement may voluntarily prepay the utilizations and the borrower
may permanently cancel all or part of the available commitments under the Revolving Facility in a minimum amount of 5,000,000 by giving not less than three business days (or such shorter period as the required majority lenders under the
Revolving Facility Agreement agree) prior notice to the Agent (as defined in the Revolving Facility Agreement).

We may reborrow amounts
repaid, subject to certain conditions, until one month prior to final maturity.

In addition to voluntary prepayments, the Revolving
Facility Agreement requires mandatory prepayment (or, as the case may be, an offer to do so) in full or in part in certain circumstances, including:



| |  |  | with respect to any lender, if it becomes unlawful for such lender to perform any of its obligations under the Revolving Facility Agreement or to maintain its participation in any loan under the Revolving Facility;
| | - |  | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | if a lender so requires in respect of that lenders participation in an outstanding loan under the Revolving Facility, upon a Change of Control (as defined in the Revolving Facility Agreement); and/or
| | - |  | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | upon the occurrence of the sale of all or substantially all of the assets of the Group.
| | - |  | ---------------------------------------------------------------------------------------

Drawdowns under the Revolving Facility are subject to satisfaction of certain conditions precedent on the date the applicable drawdown is
requested and on the date such loan is utilized including: (i) no default (or event of default for rollover of existing loans at the end of an interest period) is continuing or would result from such drawdown and (ii) certain repeating
representations and warranties specified in the Revolving Facility Agreement being true in all material respects.

The Revolving Facility
is guaranteed irrevocably and unconditionally on a joint and several basis by certain members of the Group (subject to applicable local law limitations). Borrowings under the Revolving Facility are secured by various share pledges, inter-company
loan receivables owed to the Company or any of the guarantors under the Revolving Facility and the bank accounts of the Company and the guarantors under the Revolving Facility.

The Revolving Facility Agreement contains customary operating and restrictive covenants, subject to certain agreed exceptions, qualifications
and thresholds as well as customary events of default (subject in certain cases to agreed grace periods, qualifications and thresholds), including a cross default with respect to an event of default under the Indenture (as defined below) governing
the Senior Secured Notes due 2020 (as defined below). The Revolving Facility also requires InterXion Holding N.V., each borrower and each guarantor to observe certain customary affirmative covenants (subject to certain agreed exceptions,
qualifications and thresholds) and requires InterXion Holding N.V. to comply with a leverage ratio financial covenant (calculated as the ratio of consolidated total net debt at each quarter end to pro forma EBITDA for the twelve months ending on
that quarter end).

The Indenture dated July 3, 2013, among InterXion Holding N.V., as Issuer, the initial guarantors, the Bank of
New York Mellon, London Branch, as trustee, principal paying agent and transfer agent, The Bank of New York Mellon (Luxembourg) S.A., as registrar and Luxembourg paying agent and Barclays Bank PLC, as security trustee.

On July 3, 2013, the Company issued an aggregate principal amount of 325 million 6.00% Senior Secured Notes due 2020 (the Initial
Notes). On April 29, 2014, the Company issued a further 150 million aggregate principal amount of 6.00% Senior Secured Notes due 2020 (the Additional Notes and together with the Initial Notes, the Senior Secured
Notes). The Additional Notes were issued pursuant to the same indenture as the Initial Notes.

##### Table of Contents

The aggregate 475 million Senior Secured Notes due 2020 are governed by an indenture dated
July 3, 2013, between the Company, as issuer, and The Bank of New York Mellon, London Branch as Trustee. The indenture contains customary restrictive covenants, including but not limited to limitations or restrictions on our ability to incur debt,
grant liens, make restricted payments and sell assets. The restrictive covenants are subject to customary exceptions and are governed by a consolidated fixed charge ratio to exceed 2.00 and a consolidated senior leverage ratio not to exceed 4.00.

The obligations under the 475 million Senior Secured Notes due 2020 are guaranteed by certain of the Companys subsidiaries.

The Company may redeem all or part of the 475 million Senior Secured Notes due 2020. The Company has the following redemption
rights:

may only do this, however, if:



| | (a) | at least 65% of the aggregate principal amount of Senior Secured Notes that were initially issued (calculated after giving effect to the issuance of any additional notes) would remain outstanding immediately after the

amount redeemed plus accrued and unpaid interest, if any, to the redemption date.

At any time prior to July 15, 2016, upon not less than

| | --- | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

Issue of Ordinary Shares

Our Articles provide that we may issue ordinary shares, or grant rights to subscribe for ordinary shares, pursuant to a resolution of our
general meeting of shareholders upon a proposal of our Board. Our Articles provide that our general meeting of shareholders may, upon a proposal of our Board, designate another body of the Company, which can only be our Board, as the competent body
to issue ordinary shares, or grant rights to subscribe for ordinary shares. Pursuant to our Articles and Dutch law, the period of designation may not exceed five years, but may be renewed by a resolution of our general meeting of shareholders for
periods of up to five years. If not otherwise stated in the resolution approving the designation, such designation is irrevocable. The resolution designating our Board must specify the number of shares which may be issued and, if applicable, any
conditions to the issuance.

Pursuant to a decision that was made at our general meeting of shareholders held on January 26, 2011, certain
amendments were made to our articles of association on January 28, 2011. Amongst others, our Board was designated as the corporate body competent to issue ordinary shares and to grant rights to subscribe for ordinary shares with the power to limit
or exclude pre-emptive rights related thereto. This authority is limited to a maximum equal to our authorized share capital from time to time. Our Boards authority to issue ordinary shares and grant rights to acquire ordinary shares was for a
period of five years and expired on January 28, 2016.

On June 30, 2015, our general meeting of shareholders designated our Board as
the corporate body competent to issues ordinary shares and to grant rights to subscribe for up to 4,352,281 ordinary shares, without pre-emption rights accruing to shareholders for the purpose of our employee incentive schemes, and to issues
ordinary shares and to grant rights to subscribe for ordinary shares up to 10% of the authorized share capital at that time. Our Boards authority to issue ordinary shares and grant rights to acquire ordinary shares is for a period of eighteen
months expiring on December 31, 2016. Our general meeting of shareholders may extend this period, subject to the limitations set forth above.

Ordinary shares may not be issued at less than their nominal value and must be fully paid up upon issue.

No resolution of our general meeting of shareholders or our Board is required for an issue of ordinary shares pursuant to the exercise of a
previously granted right to subscribe for ordinary shares.

##### Table of Contents

Pre-emptive Rights

Dutch law and our Articles generally give our shareholders pre-emptive rights to subscribe in proportion to the aggregate nominal value of the
shares held by the respective shareholder for any issue of new ordinary shares or grant of rights to subscribe for ordinary shares. Exceptions to these pre-emptive rights include: (i) the issue of ordinary shares and the grant of rights to
subscribe for ordinary shares to our employees, or a group company in accordance with section 2:24b of the Dutch Civil Code, (ii) the issue of ordinary shares in exchange for non-cash contributions, and (iii) the issue of ordinary shares which
are issued to a person exercising a right to subscribe for ordinary shares previously granted.

A shareholder has the legal right to
exercise pre-emption rights for at least two weeks after the date of the announcement of the issue or grant. However, our general meeting of shareholders, or our Board if so designated by our general meeting of shareholders, may restrict or exclude
pre-emptive rights. A resolution by our general meeting of shareholders to designate another corporate body, which can only be our Board, as the competent authority to exclude or restrict pre-emptive rights requires a proposal by our Board and
approval by a majority of at least two-thirds of the valid votes cast at our general meeting of shareholders if less than half of our issued and outstanding share capital is present or represented. A simple majority is sufficient if more than half
of our issued and outstanding share capital is present or represented. A resolution by our general meeting of shareholders to designate our Board as the competent authority to exclude or restrict pre-emptive rights must be for a fixed period not
exceeding five years and is only possible if our Board is simultaneously designated as the corporate body authorized to issue ordinary shares. If not otherwise stated in the resolution approving designation, such designation is irrevocable. If our
general meeting of shareholders has not designated our Board, our general meeting of shareholders itself is the corporate body authorized to restrict or exclude pre-emptive rights upon a proposal by our Board.

Our Board is designated as the corporate body authorized to limit or exclude pre-emptive rights, subject to the limited authority it has to
issue ordinary shares and grant rights to subscribe for ordinary shares as set out under Issue of Ordinary Shares above, for a period of ending on January 28, 2016. In addition, our Board is designated as the corporate body
authorized, subject to the limited authority it has to issue ordinary shares and grant rights to subscribe for ordinary shares, with our pre-emption rights accruing to shareholders for the purpose of our employee incentive schemes as set out under
Issue of Ordinary Shares above, for a period ending on December 31, 2016.

Reduction of Share Capital

Our general meeting of shareholders may, subject to Dutch law and our Articles and only upon a proposal of our Board, resolve to reduce our
issued share capital by cancellation of ordinary shares or reduction of the nominal value of ordinary shares by amendment of our Articles. A resolution of our general meeting of shareholders to reduce the issued share capital must designate the
ordinary shares to which the resolution applies and must make provisions for the implementation of such resolution. A resolution to cancel ordinary shares may only be adopted in relation to ordinary shares or depositary receipts for such shares we
hold ourselves. A partial repayment or exemption from the obligation to pay up ordinary shares must be made pro rata, unless all of our shareholders agree otherwise. A resolution at our general meeting of shareholders to reduce our issued share
capital requires a majority of at least two-thirds of the votes validly cast at a meeting at which less than half of our issued and outstanding share capital is present or represented. A simple majority is sufficient if more than half of our issued
and outstanding share capital is present or represented.

Acquisition of Ordinary Shares

We may acquire our own fully paid up ordinary shares at any time for no consideration, or, subject to certain provisions of Dutch law and our
Articles, if (i) our shareholders equity minus the payment required to make the acquisition, does not fall below the sum of called-up and paid-up share capital and any statutory reserves we must maintain by Dutch law or our Articles, and
(ii) we and our subsidiaries would thereafter not hold ordinary shares or rights of pledge over ordinary shares with an aggregate nominal value exceeding 50% of our issued and outstanding share capital.

Dutch law generally and more specifically, the Dutch Civil Code, imposes minimum capital and other reserve requirements on legal entities as a
way of protecting shareholders and creditors and maintaining the capital of a company. Such minimum capital and reserve requirements include, among other things, complying with certain minimum capital requirements when declaring and paying dividends
and repurchasing shares in its own capital, maintaining reserves on the granting of legitimate financial assistance loans by a public limited company and maintaining reserves on the re-evaluation of assets.

An acquisition of ordinary shares for a consideration must be authorized by our general meeting of shareholders. Such authorization may be
granted for a maximum period of 18 months and must specify the number of ordinary shares that may be acquired, the manner in which ordinary shares may be acquired and the price limits within which ordinary shares may be acquired. Authorization is
not required for the acquisition of ordinary shares in order to transfer them to our employees. The actual acquisition may only be effected by a resolution of our Board.

##### Table of Contents

Any ordinary shares held by us in our own capital may not be voted on or counted for quorum
purposes.

Exchange Controls and Other Provisions Relating to Non-Dutch Shareholders

There are no Dutch exchange control restrictions on investments in, or payments on, the ordinary shares. There are no special restrictions in
our Articles or Dutch law that limit the right of shareholders who are not citizens or residents of The Netherlands to hold or vote the ordinary shares.

Dividends and Distributions

We may only make distributions to our shareholders in so far as our equity exceeds the sum of our paid-in and called-up share capital plus the
reserves we are required to maintain by Dutch law or our proposed Articles. Under our Articles, our Board may determine that a portion of the profits of the current financial year shall be added to our reserves. The remaining profits are at the
disposal of our general meeting of shareholders.

We may only make distributions of dividends to our shareholders after the adoption of
our statutory annual accounts from which it appears that such distributions are legally permitted. However, our Board may resolve to pay interim dividends on account of the profits of the current financial year if the equity requirement set out
above is met, as evidenced by an interim statement of assets and liabilities relating to the condition of such assets and liabilities on a date no earlier than the first day of the third month preceding the month in which the resolution to
distribute interim dividends is made public. Our general meeting of shareholders may resolve, upon a proposal to that effect by our Board, to pay distributions at the expense of any of our reserves.

Additionally, if we choose to declare dividends, the payment of cash dividends on our shares is restricted under the terms of the agreements
governing our indebtedness.

Dividends and other distributions may be made in cash or, but only at all times with the approval of the
Board, in ordinary shares. Dividends and other distributions are due and payable as from the date determined by the corporate body resolving on the distribution. Claims to dividends and other declared distributions lapse after five years from the
date that such dividends or distributions became payable and any such amounts not collected within this period revert to us and are allocated to our general reserves.

General Meetings of Shareholders and Voting Rights

Our annual general meeting of shareholders must be held within six months after the end of each of our financial years. It must be held in The
Netherlands in Amsterdam, Haarlemmermeer (Schiphol Airport) or Hoofddorp. Our financial year coincides with the calendar year. An extraordinary general meeting of shareholders may be convened whenever our Board or CEO deems such necessary.
Shareholders representing at least 10% of our issued and outstanding share capital may, pursuant to Dutch law and our Articles, request that a general meeting of shareholders be convened, specifying the items for discussion. If our Board has not
convened a general meeting of shareholders within four weeks of such request such that such meeting can be held within six weeks following such request, the shareholders requesting such meeting are authorized to call such meeting themselves with due
observance of the relevant provisions of our Articles.

The notice convening any general meeting of shareholders must include an agenda
indicating the items for discussion, or it must state that the shareholders and any holders of depositary receipts for ordinary shares may review such agenda at our main offices in The Netherlands. We will have the notice published by electronic
means of communication which is directly and permanently accessible until the meeting and in such other manner as may be required to comply with any applicable rules of the NYSE. The explanatory notes to the agenda must contain all facts and
circumstances that are relevant for the proposals on the agenda. Such explanatory notes and the agenda will be placed on our website.

Shareholders holding at least 1% of our issued and outstanding share capital or ordinary shares representing a value of at least
50 million may submit agenda proposals for any general meeting of shareholders. Provided we receive such proposals no later than 60 days before the date of the general meeting of shareholders, and provided that such proposal does not,
according to our Board, conflict with our vital interests, we will have the proposals included in the notice.

##### Table of Contents

Each of the ordinary shares confers the right to cast one vote. Each shareholder entitled to
participate in a general meeting of shareholders, either in person or through a written proxy, is entitled to attend and address the meeting and, to the extent that the voting rights accrue to him, to exercise his voting rights in accordance with
our Articles. The voting rights attached to any ordinary shares, or ordinary shares for which depositary receipts have been issued, are suspended as long as they are held in treasury.

Our Board may allow shareholders to, in person or through a person holding a written proxy, participate in a general meeting of shareholders,
including to take the floor and, to the extent applicable, to exercise voting rights, through an electronic means of communication. Our Board selects the means of electronic communication and may subject its use to conditions.

To the extent that our Articles or Dutch law do not require a qualified majority, all resolutions of our general meeting of shareholders shall
be adopted by a simple majority of the votes cast.

The following resolutions of our general meeting of shareholders may only be adopted
upon a proposal by our Board:



| | (a) | to effect a statutory merger (juridische fusie) or demerger (juridische splitsing);
| | --- | -----------------------------------------------------------------------------------



| | (b) | to issue ordinary shares or to restrict or exclude pre-emption rights on ordinary shares to the extent the authority to issue has not been delegated to our Board;
| | --- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | (c) | to designate our Board as the corporate body authorized to issue ordinary shares or rights to subscribe for ordinary shares and to restrict or to exclude the pre-emption rights on ordinary shares or rights to subscribe
for ordinary shares;
| | --- | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | (d) | to reduce our issued share capital;
| | --- | -----------------------------------



| | (e) | to make a whole or partial distribution of reserves;
| | --- | ----------------------------------------------------



| | (f) | to amend our articles of association or change our corporate form; and
| | --- | ----------------------------------------------------------------------



| | (g) | to dissolve us.
| | --- | ---------------

Amendment of our Articles of Association

Our general meeting of shareholders may resolve to amend our Articles upon a proposal made by our Board.

Dissolution and Liquidation

Under our Articles, we may be dissolved by a resolution of our general meeting of shareholders upon a proposal of our Board.

In the event of dissolution, our business will be liquidated in accordance with Dutch law and our Articles and the liquidation shall be
effected by our Board. During liquidation, the provisions of our Articles will remain in force to the extent possible. Any assets remaining upon completion of the dissolution will be distributed to the holders of ordinary shares in proportion to the
aggregate nominal amount of their ordinary shares.

Disclosure of Information

Dutch law contains specific rules intended to prevent insider trading, tipping and market manipulation. We are subject to these rules and
accordingly, we have adopted a code of securities dealings in relation to our securities.

Squeeze Out

If a shareholder, alone or together with group companies, (the Controlling Entity) holds a total of at least 95% of a
companys issued share capital by nominal value for its own account, Dutch law permits the Controlling Entity to acquire the remaining shares in the controlled entity (the Controlled Entity) by initiating proceedings against the
holders of the remaining shares. The price to be paid for such shares will be determined by the Enterprise Chamber of the Amsterdam Court of Appeal (the Enterprise Chamber). A Controlling Entity that holds less than 95% of the shares in
the Controlled Entity, but that in practice controls the Controlled Entitys general meeting of shareholders, could attempt to obtain full ownership of the business of the Controlled Entity through a legal merger of the Controlled Entity with
another company controlled by the Controlling Entity, by subscribing to additional shares in the Controlled Entity (for example, in exchange for a contribution of part of its own business), through another form of reorganization aimed at raising its
interest to 95% or through other means.

In addition to the general squeeze-out procedure mentioned above, following a public offer a
holder of at least 95% of the outstanding shares and voting rights has the right to require the minority shareholders to sell their shares to it. To the extent there are two or more types of shares the request can only be made with regard to the
type of shares of which the shareholder holds at least 95% in aggregate representing at least 95% of the voting rights attached to those shares. Any request to require the minority shareholders to sell their shares must be filed with the Enterprise
Chamber within three months after the end of the acceptance period of the public offer. Conversely, in such a case, each minority shareholder has the right to require the holder of at least 95% of the outstanding shares and voting rights to purchase
its shares. The minority shareholders must file such claim with the Enterprise Chamber within three months after the end of the acceptance period of the public offer.

Reporting of Insider Transactions

Pursuant to the Dutch Financial Supervision Act, the Directors and any other person who has managerial responsibilities or who has the
authority to make decisions affecting our future developments and business prospects or who has regular access to inside information relating, directly or indirectly, to us (each an Insider), must notify The Netherlands Authority for the
Financial Markets (AFM) of all transactions conducted for his own account relating to ordinary shares or securities the value of which is determined by the value of ordinary shares. The Netherlands Authority for the Financial Markets
must be notified within five days following the transaction date. Notification may be postponed until the date the value of the transactions amounts to 5,000 or more per calendar year.

In addition, persons designated by the Decree on Market Abuse pursuant to the Dutch Financial Supervision Act (Besluit Marktmisbruik
Wft) (the Market Abuse Decree) who are closely associated with an Insider must notify The Netherlands Authority for the Financial Markets of any transactions conducted for their own account relating to ordinary shares or securities
the value of which is determined by the value of the ordinary shares. The Market Abuse Decree designates the following categories of persons: (i) the spouse or any partner considered by national law as equivalent to the spouse,
(ii) dependent children, (iii) other relatives who have shared the same household for at least one year prior to the relevant transaction date, and (iv) any legal person, trust or partnership whose managerial responsibilities are
discharged by, which is controlled by, which has been incorporated for the benefit of, or whose economic interests are the same as, a person referred to in the previous paragraph or under (i), (ii) or (iii) above.

The AFM keeps a public register of all notifications made pursuant to the Dutch Financial Supervision Act.

Pursuant to the rules against insider trading we have, among other things, further adopted rules governing the holding of, reporting and
carrying out of transactions in our securities by the Directors or our employees. Further, we have drawn up a list of those persons working for us who could have access to inside information on a regular or incidental basis and have informed the
persons concerned of the rules against insider trading and market manipulation including the sanctions which can be imposed in the event of a violation of those rules.

Non-compliance with the notification obligations under the market abuse obligations laid down in the Dutch Financial Supervision Act may lead
to criminal fines, administrative fines, imprisonment or other sanctions.

Comparison of Dutch Corporate Law and U.S. Corporate Law

The following comparison between Dutch corporation law, which applies to us, and Delaware corporation law, the law under which
many corporations in the United States are incorporated, discusses additional matters not otherwise described in this annual report.

Duties of directors

The Netherlands

Under Dutch law the board of directors is collectively responsible for the policy and day-to-day management of the Company. The non-executive
directors will be assigned the task of supervising the executive directors and providing them with advice. Each director has a duty to the Company to properly perform the duties assigned to him. Furthermore, each board member has a duty to act in
the corporate interest of the Company. Under Dutch law, the corporate interest extends to the interests of all corporate stakeholders, such as shareholders, creditors, employees, customers and suppliers. The duty to act in the corporate interest of
the Company also applies in the event of a proposed sale or break-up of the Company, whereby the circumstances generally dictate how such duty is to be applied. Any board resolution regarding a significant change in the identity or character of the
Company or its business requires shareholders approval.

Delaware

The board of directors of a Delaware corporation bears the ultimate responsibility for managing the business and affairs of a corporation. In
discharging this function, directors of a Delaware corporation owe fiduciary duties of care and loyalty to the corporation and to its shareholders. Delaware courts have decided that the directors of a Delaware corporation are required to exercise an
informed business judgment in the performance of their duties. An informed business judgment means that the directors have informed themselves of all material information reasonably available to them. Delaware courts have also imposed a heightened
standard of conduct upon directors of a Delaware corporation who take any action designed to defeat a threatened change in control of the corporation. In addition, under Delaware law, when the board of directors of a Delaware corporation approves
the sale or break-up of a corporation, the board of directors may, in certain circumstances, have a duty to obtain the highest value reasonably available to the shareholders.

Director terms

The Netherlands

Under Dutch law a director of a listed company is generally appointed for a maximum term of four years. There is no limit to the number of
terms a director may serve.

Delaware

The Delaware General Corporation Law generally provides for a one-year term for directors, but permits directorships to be divided into up to
three staggered classes with up to three-year terms, with the terms for each class expiring in different years, if permitted by the certificate of incorporation, an initial bylaw or a bylaw adopted by the shareholders, with exceptions if the board
is classified or if the company has cumulative voting.

Director vacancies

The Netherlands

Under Dutch law, new members of the board of directors of a company such as ours are appointed by the general meeting. Our Articles provide
that our Board has nomination rights with respect to the appointment of a new member of our Board. If a nomination consists of a list of two or more candidates, it is binding and the appointment to the vacant seat concerned shall be from the persons
placed on the binding list of candidates and shall be effected through election. Notwithstanding the foregoing, our general meeting of shareholders may, at all times, by a resolution passed with a two-thirds majority of the votes cast representing
more than half of our issued and outstanding capital, resolve that such list of candidates shall not be binding.

Delaware

The Delaware General Corporation Law provides that vacancies and newly created directorships may be filled by a majority of the
directors then in office (even though less than a quorum) unless (a) otherwise provided in the certificate of incorporation or by-laws of the corporation or (b) the certificate of incorporation directs that a particular class of stock is
to elect such director, in which case any other directors elected by such class, or a sole remaining director elected by such class, will fill such vacancy.

Shareholder proposals

The Netherlands

Pursuant to our Articles, extraordinary shareholders meetings will be held as often as our Board or our CEO deems such necessary.
Additionally, shareholders and/or persons with depository receipt holder rights representing in the aggregate at least one-tenth of the issued capital of the Company may request the Board to convene a general meeting, specifically stating the
business to be discussed. If our Board has not given proper notice of a general meeting within four weeks following receipt of such request such that the meeting can be held within six weeks after receipt of the request, the applicants shall be
authorized to convene a meeting themselves. Pursuant to Dutch law, one or more shareholders representing at least 10% of the issued share capital may request the Dutch Courts to order that a general meeting be held.

The agenda for a meeting of shareholders must contain such items as our Board or the person or persons convening the meeting decide, including
the time and place of the shareholders meeting and the procedure for participating in the shareholders meeting by way of a written power of attorney. The agenda shall also include such other items as one or more shareholders,
representing at least such part of the issued share capital as required by the laws of the Netherlands (currently, 1% of the issued share capital or shares representing a value of 50 million) may request by providing a substantiated written
request or a proposal for a resolution to our Board at least 60 days before the date of the meeting.

Delaware

Delaware law does not specifically grant shareholders the right to bring business before an annual or special meeting.

Shareholder suits

The Netherlands

In the event a third party is liable to a Dutch company, only the company itself can bring a civil action against that party. The individual
shareholders do not have the right to bring an action on behalf of the company. Only in the event that the cause for the liability of a third party to the company also constitutes a tortious act directly against a shareholder does that shareholder
have an individual right of action against such third party in its own name. The Dutch Civil Code provides for the possibility to initiate such actions collectively. A foundation or an association whose objective is to protect the rights of a group
of persons having similar interests can institute a collective action. The collective action itself cannot result in an order for payment of monetary damages but may only result in a declaratory judgment (verklaring voor recht). In order to
obtain compensation for damages, the foundation or association and the defendant may reachoften on the basis of such declaratory judgmenta settlement. A Dutch court may declare the settlement agreement binding upon all the injured
parties with an opt-out choice for an individual injured party. An individual injured party may also itself institute a civil claim for damages.

Delaware

Under the Delaware General Corporation Law, a shareholder may bring a derivative action on behalf of the corporation to enforce the rights of
the corporation. An individual also may commence a class action suit on behalf of himself and other similarly situated shareholders where the requirements for maintaining a class action under Delaware law have been met. A person may institute and
maintain such a suit only if that person was a shareholder at the time of the transaction which is the subject of the suit. In addition, under Delaware case law, the plaintiff normally must be a shareholder not only at the time of the transaction
that is the subject of the suit, but also throughout the duration of the derivative suit. Delaware law also requires that the derivative plaintiff make a demand on the directors of the corporation to assert the corporate claim and such demand has
been refused before the suit may be prosecuted by the derivative plaintiff in court, unless such a demand would be futile.

Anti-takeover provisions

The Netherlands

Neither Dutch law nor our Articles specifically prevent business combinations with interested shareholders. Under Dutch law various protective
measures are as such possible and admissible, within the boundaries set by Dutch case law and Dutch law.

Delaware

In addition to other aspects of Delaware law governing fiduciary duties of directors during a potential takeover, the Delaware
General Corporation Law also contains a business combination statute that protects Delaware companies from hostile takeovers and from actions following the takeover by prohibiting some transactions once an acquirer has gained a significant holding
in the corporation.

Section 203 of the Delaware General Corporation Law prohibits business combinations, including
mergers, sales and leases of assets, issuances of securities and similar transactions by a corporation or a subsidiary with an interested shareholder that beneficially owns 15% or more of a corporations voting stock, within three years after
the person becomes an interested shareholder, unless:



| |  |  | the transaction that will cause the person to become an interested shareholder is approved by the board of directors of the target prior to the transactions;
| | - |  | -------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | after the completion of the transaction in which the person becomes an interested shareholder, the interested shareholder holds at least 85% of the voting stock of the corporation not including shares owned by persons
who are directors and also officers of interested shareholders and shares owned by specified employee benefit plans; or
| | - |  | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

##### Table of Contents

| |  |  | after the person becomes an interested shareholder, the business combination is approved by the board of directors of the corporation and holders of at least 66.67% of the outstanding voting stock, excluding shares held
by the interested shareholder.
| | - |  | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

A Delaware corporation may elect not to be governed by Section 203 by a provision
contained in the original certificate of incorporation of the corporation or an amendment to the original certificate of incorporation or to the bylaws of the Company, which amendment must be approved by a majority of the shares entitled to vote and
may not be further amended by the board of directors of the corporation. Such an amendment is not effective until twelve months following its adoption.

Removal of directors

The Netherlands

Under Dutch law, the general meeting has the authority to suspend or remove members of the board of directors at any time. Under our Articles,
a member of our Board may be suspended or removed by our general meeting of shareholders at any time by a resolution passed with a two-thirds majority of the votes cast representing more than half of the issued and outstanding capital. If permitted
under the laws of The Netherlands, a member of our Board may also be suspended by our Board itself. Any suspension may not last longer than three months in the aggregate. If, at the end of that period, no decision has been taken on termination of
the suspension, the suspension shall end. Currently, Dutch law does not allow directors to be suspended by the board of directors; however, Dutch law is expected to be amended to facilitate the suspension of directors by the board of directors.

Delaware

Under the Delaware General Corporation Law, any director or the entire board of directors may be removed, with or without cause, by the holders
of a majority of the shares then entitled to vote at an election of directors, except (a) unless the certificate of incorporation provides otherwise, in the case of a corporation whose board is classified, shareholders may effect such removal
only for cause, or (b) in the case of a corporation having cumulative voting, if less than the entire board is to be removed, no director may be removed without cause if the votes cast against his removal would be sufficient to elect him if
then cumulatively voted at an election of the entire board of directors, or, if there are classes of directors, at an election of the class of directors of which he is a part.

Taxation

Certain U.S. Federal Income
Tax Considerations

This section describes certain material United States federal income tax consequences of owning our ordinary
shares. It applies to a US Holder (as defined below) that holds our ordinary shares as capital assets for tax purposes. This section does not apply to a US Holder that is a member of a special class of holders subject to special rules, such as:



| |  |  | a financial institution,
| | - |  | ------------------------



| |  |  | a dealer in securities,
| | - |  | -----------------------



| |  |  | a trader in securities that elects to use a mark-to-market method of accounting for its securities holdings,
| | - |  | ------------------------------------------------------------------------------------------------------------



| |  |  | a real estate investment trust;
| | - |  | -------------------------------



| |  |  | a regulated investment company;
| | - |  | -------------------------------



| |  |  | U.S. expatriates;
| | - |  | -----------------



| |  |  | persons who acquired shares pursuant to the exercise of any employee share option or otherwise as compensation;
| | - |  | ---------------------------------------------------------------------------------------------------------------



| |  |  | a tax-exempt organization,
| | - |  | --------------------------



| |  |  | an insurance company,
| | - |  | ---------------------



| |  |  | a person liable for alternative minimum tax,
| | - |  | --------------------------------------------



| |  |  | a person that actually or constructively owns 10% or more of our voting stock,
| | - |  | ------------------------------------------------------------------------------



| |  |  | a person that owns shares through a partnership or other pass-through entity,
| | - |  | -----------------------------------------------------------------------------



| |  |  | a person that holds shares as part of a straddle or a hedging or conversion transaction, or
| | - |  | -------------------------------------------------------------------------------------------



| |  |  | a person whose functional currency is not the US dollar.
| | - |  | --------------------------------------------------------

##### Table of Contents

This section is based on the Internal Revenue Code of 1986, as amended (the Code),
its legislative history, existing and proposed regulations, published rulings and court decisions, all as currently in effect. These laws are subject to change, possibly on a retroactive basis.

This section does not describe any tax consequences arising out of the tax laws of any state, local or non-U.S. jurisdiction, any estate or
gift tax consequences or the Medicare tax on certain net investment income. If any entity or arrangement that is treated as a partnership for United States federal income tax purposes is a beneficial owner of our ordinary shares, the
treatment of a partner in the partnership will generally depend on the status of the partner and the activities of the partnership. Partners in such partnerships should consult with their tax advisors.

For purposes of this discussion, a US Holder is a beneficial owner of our ordinary shares that is for United States federal income tax
purposes:



| |  |  | a citizen or resident of the United States,
| | - |  | -------------------------------------------



| |  |  | a US domestic corporation (or other entity taxable as a US domestic corporation for United States federal income tax purposes),
| | - |  | -------------------------------------------------------------------------------------------------------------------------------



| |  |  | an estate the income of which is subject to United States federal income tax regardless of its source, or
| | - |  | ---------------------------------------------------------------------------------------------------------



| |  |  | a trust, if a United States court can exercise primary supervision over the trusts administration and one or more United States persons are authorized to control all substantial decisions of the trust, or if the
trust has a valid election in effect to be treated as a United States person.
| | - |  | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

US Holders should consult their own tax
advisor regarding the United States federal, state and local and other tax consequences of owning and disposing of our ordinary shares in their particular circumstances.

Taxation of Dividends

Under the
United States federal income tax laws, and subject to the passive foreign investment company, or PFIC, rules discussed below, US Holders will include in gross income the gross amount of any dividend paid by us out of our current or accumulated
earnings and profits (as determined for United States federal income tax purposes). The dividend is ordinary income that the US Holder must include in income when the dividend is actually or constructively received. The dividend will not be eligible
for the dividends-received deduction generally allowed to United States corporations in respect of dividends received from other United States corporations. The amount of a dividend distribution paid in euros includible in the income of a US Holder
will be the US dollar value of the euro payment made, determined at the spot euro/US dollar rate on the date the dividend distribution is includible in the income of the US Holder, regardless of whether the payment is in fact converted into US
dollars. Generally, any gain or loss resulting from currency exchange fluctuations during the period from the date the dividend payment is includible in income to the date such payment is converted into US dollars will be treated as ordinary income
or loss. Such gain or loss generally will be income or loss from sources within the United States for foreign tax credit limitation purposes. Distributions in excess of current and accumulated earnings and profits, as determined for United States
federal income tax purposes, will be treated as a non-taxable return of capital to the extent of the US Holders basis in the shares and thereafter as capital gain. We currently do not, and we do not intend to, calculate our earnings and
profits under United States federal income tax principles. Therefore, a US Holder should expect that a distribution will generally be reported as a dividend even if that distribution would otherwise be treated as a non-taxable return of capital or
as capital gain under the rules described above.

With respect to non-corporate taxpayers, dividends may be taxed at the lower applicable
capital gains rate provided that (1) either (a) our ordinary shares are readily tradable on an established securities market in the United States or (b) we are eligible for the benefits of the Convention between the United
States of America and the Kingdom of The Netherlands for the avoidance of double taxation and the prevention of fiscal evasion with respect to taxes on income, (2) we are not a PFIC (as discussed below) for either our taxable year in
which the dividend was paid or the preceding taxable year, and (3) certain holding period requirements are met. Common stock is considered for purposes of clause (1) above to be readily tradable on an established securities market if it is
listed on the NYSE. US Holders should consult their tax advisors regarding the availability of the lower rate for dividends paid with respect to our ordinary shares.

For foreign tax credit limitation purposes, the dividend will generally constitute foreign source income and will generally be passive
category income but could, in the case of certain US Holders, constitute general category income. If the dividends are taxed as qualified dividend income (as discussed above), the amount of the dividend taken into account for
purposes of calculating the foreign tax credit limitation will in general be limited to the gross amount of the dividend, multiplied by the reduced tax rate applicable to qualified dividend income and divided by the highest tax rate normally
applicable to dividends.

##### Table of Contents

If Dutch withholding taxes apply to any dividends paid to you with respect to our ordinary
shares, the amount of the dividend would include withheld Dutch taxes and, subject to certain conditions and limitations, such Dutch withholding taxes may be eligible for credit against your U.S. federal income tax liability. The rules relating to
the determination of the foreign tax credit are complex, and you should consult your tax advisors regarding the availability of a foreign tax credit in your particular circumstances, including the effects of any applicable income tax treaties.

Taxation of Capital Gains

Subject to the PFIC rules discussed below, upon the sale or other disposition of our ordinary shares, a US Holder will generally recognize
capital gain or loss for United States federal income tax purposes equal to the difference between the US Holders amount realized and the US Holders tax basis in such shares. If a US Holder receives consideration for shares paid in a
currency other than US dollars, the US Holders amount realized will be the US dollar value of the payment received. In general, the US dollar value of such a payment will be determined on the date of sale or disposition. On the settlement
date, a US Holder may recognize US source foreign currency gain or loss (taxable as ordinary income or loss) equal to the difference (if any) between the US dollar value of the amount received based on the exchange rates in effect on the date of
sale or other disposition and the settlement date. However, if our ordinary shares are treated as traded on an established securities market and the US Holder is a cash basis taxpayer or an accrual basis taxpayer who has made a special election, the
US dollar value of the amount realized in a foreign currency is determined by translating the amount received at the spot rate of exchange on the settlement date, and no exchange gain or loss would be recognized at that time. Capital gain of a
non-corporate US Holder is generally taxed at a reduced rate where the property is held more than one year. The gain or loss will generally be income or loss from sources within the United States for foreign tax credit limitation purposes.

PFIC Rules

We believe that our
ordinary shares should not be treated as stock of a PFIC for United States federal income tax purposes for the taxable year that ended on December 31, 2015. However, the application of the PFIC rules is subject to uncertainty in several
respects, and we cannot assure you that the United States Internal Revenue Service will not take a contrary position. In addition, PFIC status is a factual determination which cannot be made until the close of the taxable year. Accordingly, there is
no guarantee that we will not be a PFIC for any future taxable year. Furthermore, because the total value of our assets for purposes of the asset test generally will be calculated using the market price of our ordinary shares, our PFIC status will
depend in large part on the market price of our ordinary shares. Accordingly, fluctuations in the market price of our ordinary shares could render us a PFIC for any year. A non-U.S. corporation is considered a PFIC for any taxable year if either:



| |  |  | at least 75% of its gross income is passive income, or
| | - |  | ------------------------------------------------------



| |  |  | at least 50% of the value of its assets (based on an average of the quarterly values of the assets during a taxable year) is attributable to assets that produce or are held for the production of passive income (the
asset test).
| | - |  | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

In the PFIC determination, we will be treated as owning our proportionate share of the assets and
earning our proportionate share of the income of any other corporation in which we own, directly or indirectly, 25% or more (by value) of the stock.

If we were to be treated as a PFIC for any year during a US Holders holding period, unless the US Holder elects to be taxed annually on
a mark-to-market basis with respect to the shares (which election may be made only if our ordinary shares are marketable stock within the meaning of Section 1296 of the Code), the US Holder will be subject to special tax rules with
respect to any excess distribution received and any gain realized from a sale or other disposition (including a pledge) of that holders shares. Distributions a US Holder receives in a taxable year that are greater than 125% of the
average annual distributions received during the shorter of the three preceding taxable years or the holders holding period for the shares will be treated as excess distributions. Under these special tax rules:



| |  |  | the excess distribution or gain will be allocated ratably over the US Holders holding period for the shares;
| | - |  | -------------------------------------------------------------------------------------------------------------



| |  |  | the amount allocated to the current taxable year, and any taxable year prior to the first taxable year in which we are treated as a PFIC, will be treated as ordinary income; and
| | - |  | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | the amount allocated to each other year will be subject to tax at the highest tax rate in effect for that year and the interest charge generally applicable to underpayments of tax will be imposed on the resulting tax
attributable to each such year.
| | - |  | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



85



---

##### Table of Contents

The tax liability for amounts allocated to years prior to the year of disposition or excess
distribution cannot be offset by any net operating losses for such years, and gains (but not losses) realized on the sale of the shares cannot be treated as capital, even if the shares are held as capital assets. If we were to be treated as a
PFIC for any year during which a US Holder holds the shares, we generally would continue to be treated as a PFIC with respect to that US Holder for all succeeding years during which it owns our ordinary shares. If we were to cease to be treated as a
PFIC, however, a US Holder may avoid some of the adverse effects of the PFIC regime by making a deemed sale election with respect to our ordinary shares.

If a US Holder holds shares in any year in which we are a PFIC, that US Holder will generally be required by the Code to file an information
report with the Internal Revenue Service containing such information as the Internal Revenue Service may require.

Information
Reporting and Backup Withholding

Dividend payments with respect to our shares and proceeds from the sale, exchange or redemption
of our ordinary shares may be subject to information reporting to the United States Internal Revenue Service and possible United States backup withholding. Backup withholding will not apply, however, to a US Holder that furnishes a correct taxpayer
identification number and makes any other required certification or that is otherwise exempt from backup withholding. US Holders that are required to establish their exempt status generally must provide such certification on United States Internal
Revenue Service Form W-9. US Holders should consult their tax advisors regarding the application of the U.S. information reporting and backup withholding rules.

Backup withholding is not an additional tax. Amounts withheld as backup withholding may be credited against your United States federal income
tax liability, and you may obtain a refund of any excess amounts withheld under the backup withholding rules by filing the appropriate claim for refund with the United States Internal Revenue Service and furnishing any required information in a
timely manner.

Information with respect to Foreign Financial Assets

U.S. individuals that own specified foreign financial assets with an aggregate value in excess of certain threshold amounts are
generally required to file an information report with respect to such assets with their tax returns. Specified foreign financial assets include any financial accounts maintained by foreign financial institutions, as well as any of the
following, but only if they are not held in accounts maintained by certain financial institutions: (i) stocks and securities issued by non-U.S. persons, (ii) financial instruments and contracts held for investment that have non-U.S.
issuers or counterparties, and (iii) interests in foreign entities. Our shares may be subject to these rules. Under certain circumstances, an entity may be treated as an individual for purposes of these rules. US Holders that are individuals should
consult their tax advisers regarding the application of this requirement to their ownership of our shares.

Certain Dutch Tax Considerations

Introduction

This
section describes the material Dutch tax consequences of the ownership and disposition of our ordinary shares as of the date hereof and is intended as general information only. The following summary does not purport to be a comprehensive description
of all Dutch tax considerations that could be relevant for holders of the ordinary shares. This summary is intended as general information only. Each prospective holder should consult a professional tax adviser with respect to the tax consequences
of an investment in the ordinary shares. This summary is based on Dutch tax legislation and published case law in force as of the date of this annual report. It does not take into account any developments or amendments thereof after that date,
whether or not such developments or amendments have retroactive effect.

For the purpose of this section, The Netherlands
shall mean the part of the Kingdom of The Netherlands in Europe.

Scope

Regardless of whether or not a holder of ordinary shares is, or is treated as being, a resident of The Netherlands, this summary does not
address the Dutch tax consequences for such a holder:



| | (a) | having a substantial interest (aanmerkelijk belang) in our Company (such a substantial interest is generally present if an equity stake, profit stake of at least 5%, or a right to acquire such an equity/profit
stake, is held, in each case by reference to our Companys total issued share capital, or the issued capital of a certain class of shares);
| | --- | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

##### Table of Contents

| | (b) | who is a private individual and may be taxed for the purposes of Dutch income tax (inkomstenbelasting) as an entrepreneur (ondernemer) having an enterprise (onderneming) to which the ordinary shares
are attributable, as one who earns income from miscellaneous activities (resultaat uit overige werkzaamheden), which include the performance of activities with respect to the ordinary shares that exceed regular, active portfolio management
(normaal, actief vermogensbeheer), or who may otherwise be taxed as one earning taxable income from work and home (werk en woning) with respect to benefits derived from the ordinary shares;
| | --- | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | (c) | which is a corporate entity, and for the purposes of Dutch corporate income tax (vennootschapsbelasting) and Dutch dividend tax (dividendbelasting), has, or is deemed to have, a participation
(deelneming) in our Company (such a participation is generally present in the case of an interest of at least 5% of our Companys nominal paid-in capital); or
| | --- | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | (d) | which is a corporate entity and an exempt investment institution (vrijgestelde beleggingsinstelling) or investment institution (beleggingsinstelling) for the purposes of Dutch corporate income tax, a
pension fund, or otherwise not a taxpayer or exempt for tax purposes.
| | --- | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

Dividend tax

Withholding requirement

We are required to withhold 15% Dutch dividend tax in respect of proceeds from the ordinary shares, which include, but is not limited to:



| | (a) | proceeds in cash or in kind, including deemed and constructive proceeds;
| | --- | ------------------------------------------------------------------------



| | (b) | liquidation proceeds, proceeds on redemption of the ordinary shares and, as a rule, the consideration for the repurchase of ordinary shares by our Company in excess of its average paid-in capital (gestort
kapitaal) as recognized for Dutch dividend tax purposes, unless a particular statutory exemption applies;
| | --- | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | (c) | the par value of the ordinary shares issued to a holder, or an increase in the par value of the ordinary shares, except when the (increase in the) par value of the ordinary shares is funded out of our paid-in capital as
recognized for Dutch dividend tax purposes; and
| | --- | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | (d) | partial repayments of paid-in capital, if and to the extent there are qualifying profits (zuivere winst), unless the general meeting of holders of shares has resolved in advance to make such repayment and
provided that the nominal value of the ordinary shares concerned has been reduced by an equal amount by way of an amendment of the articles of association and the capital concerned is recognized as paid-in capital for Dutch dividend tax purposes.
| | --- | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

Resident holders

If a holder of ordinary shares is, or is treated as being, a resident of The Netherlands, Dutch dividend tax which is withheld with respect to
proceeds from the ordinary shares will generally be creditable for Dutch corporate income tax or Dutch income tax purposes if the holder is the beneficial owner (uiteindelijk gerechtigde) of the proceeds concerned. A resident corporate holder
of ordinary shares may under certain conditions be entitled to an exemption from Dutch dividend withholding tax.

Non-resident holders

If a private individual holder of ordinary shares is, or is treated as being, a resident of a country other than The Netherlands, such
holder is generally not entitled to claim full or partial relief at source, or a refund in whole or in part, of Dutch dividend tax with respect to proceeds from the ordinary shares. A non-resident corporate holder of ordinary shares may under
certain conditions be entitled to an exemption from, reduction or refund of Dutch dividend withholding tax under the provisions of a treaty for the avoidance of double taxation between The Netherlands and its country of residence.

Income tax

Resident holders

A holder
who is a private individual and a resident, or treated as being, a resident of The Netherlands for the purposes of Dutch income tax and who does not have a substantial interest in our Company nor otherwise is taxed in relation to the ordinary shares
as one earning taxable income from work and home, must record the ordinary shares as assets that are held in box 3. Taxable income with regard to the ordinary shares is then determined on the basis of a deemed return on income from savings and
investments (sparen en beleggen), rather than on the basis of income actually received or gains actually realized. This deemed return is fixed at a rate of 4% of the holders yield basis (rendementsgrondslag) on January 1 of
each year, insofar as the yield basis concerned exceeds a certain threshold. Such yield basis is determined as the fair market value of certain qualifying assets held by the holder of the ordinary shares, less the fair market value of certain
qualifying liabilities. The fair market value of the ordinary shares will be included as an asset in the holders yield basis. The deemed return of 4% on the holders yield basis, being the fair market value of the ordinary shares, is
taxed at a rate of 30% (insofar as the yield basis concerned exceeds a certain threshold).

Non-resident holders

A holder who is a private individual and neither a resident, nor treated as being a resident of The Netherlands for the purposes of Dutch
income tax, will not be subject to such tax in respect of benefits derived from the ordinary shares.

Corporate income tax

Resident holders or holders having a Dutch permanent establishment

A holder which is a corporate entity and for the purposes of Dutch corporate income tax a resident (or treated as being a resident) of The
Netherlands, or a non-resident having (or treated as having) a permanent establishment in The Netherlands, is generally taxed in respect of benefits derived from the ordinary shares at rates of up to 25%.

Non-resident holders

A
holder which is a corporate entity and for the purposes of Dutch corporate income tax neither a resident, nor treated as being a resident, of The Netherlands, having no permanent establishment in The Netherlands (and is not treated as having such a
permanent establishment), will generally not be subject to such tax in respect of benefits derived from the ordinary shares.

Gift
and inheritance tax

Resident holders

Dutch gift tax or inheritance tax (schenk- of erfbelasting) will arise in respect of an acquisition (or deemed acquisition) of the
ordinary shares by way of a gift by, or on the death of, a holder of ordinary shares who is a resident, or treated as being a resident, of The Netherlands for the purposes of Dutch gift and inheritance tax. A holder is so treated as being a resident
of The Netherlands, if one having Dutch nationality has been a resident of The Netherlands during the ten years preceding the relevant gift or death. A holder is further so treated as being a resident of The Netherlands, if one has been a resident
of The Netherlands at any time during the twelve months preceding the time of the relevant gift.

Non-resident holders

No Dutch gift tax or inheritance tax will arise in respect of an acquisition (or deemed acquisition) of the ordinary shares by way of a gift
by, or on the death of, a holder of ordinary shares who is neither a resident, nor treated as being a resident, of The Netherlands for the purposes of Dutch gift and inheritance tax.

Other taxes

No
Dutch turnover tax (omzetbelasting) will arise in respect of any payment in consideration for the issue of the ordinary shares, with respect to a distribution of proceeds from the ordinary shares or with respect to a transfer of ordinary
shares. Furthermore, no Dutch registration tax, capital tax, transfer tax or stamp duty (nor any other similar tax or duty) will be payable in connection with the issue or acquisition of the ordinary shares.

ITEM 11: QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET
RISK

Interest Rate Risk

Under
our Revolving Facility, interest is based on a floating rate index. The interest expense on the remainder of our outstanding indebtedness is based on a fixed rate, except for our mortgages. Our mortgages are subject to a floating interest rate of
EURIBOR plus an individual margin ranging from 200 to 275 basis points. We have determined that the impact of a near-term 10% appreciation or depreciation of EURIBOR would not have a significant effect on our financial position, results of
operations, or cash flows. The interest rates on our mortgages secured by our PAR3 and PAR5 properties was fixed for approximately 75% of the principal outstanding amounts for a period of 10 years.

As of December 31, 2015 the interest payable under the Revolving Facility on (i) any EUR amounts drawn would be at the rate of EURIBOR plus
350 basis points per annum, (ii) any Danish Kroner amounts drawn would be at the rate of CIBOR plus 350 basis points per annum, (iii) any Swedish Kroner amounts drawn would be at the rate of STIBOR plus 350 basis points per annum and (iv) other
applicable currencies including GBP amounts drawn at the rate of LIBOR plus 350 basis points per annum. The Revolving Facility was undrawn as of December 31, 2015.

Foreign Exchange Rate Risk

Our reporting
currency for purposes of our financial statements is the euro. However, we also incur revenue and operating costs in non-euro denominated currencies, such as British pounds, Swiss francs, Danish Kroner and Swedish Kroner. We recognize foreign
currency gains or losses arising from our operations in the period incurred. As a result, currency fluctuations between the euro and the non-euro currencies in which we do business will cause us to incur foreign currency translation gains and
losses. We cannot predict the effects of exchange rate fluctuations upon our future operating results because of the number of currencies involved, the variability of currency exposure and the potential volatility of currency exchange rates. We have
determined that the impact of a near-term 10% appreciation or depreciation of non-euro denominated currencies relative to the euro would not have a significant effect on our financial position, results of operations, or cash flows.

We do not maintain any derivative instruments to mitigate the exposure to translation and transaction risk. Our foreign exchange transaction
gains and losses are included in our results of operations and were not material for all periods presented. We do not currently engage in foreign exchange hedging transactions to manage the risk of our foreign currency exposure.

Commodity Price Risk

We are a
significant user of electricity and have exposure to increases in electricity prices. In recent years, we have seen significant increases in electricity prices. We use independent consultants to monitor price changes in electricity and negotiate
fixed-price term agreements with the power supply companies where possible.

Approximately 60% of our customers by revenue pay for
electricity on a metered basis while the remainder of our customers pay for power plugs. While we are contractually able to recover energy cost increases from our customers, some portion of the increased costs may not be recovered. In
addition, some portion of the increased costs may be recovered in a delayed fashion based on commercial reasons at the discretion of local management.

ITEM 15: CONTROLS AND PROCEDURES

Conclusion Regarding the Effectiveness of Disclosure Controls and Procedures

Under the supervision and with the participation of the Chief Executive Officer (CEO) and Chief Financial Officer (CFO), the effectiveness of
the Companys disclosure controls and procedures (as defined in Rules 13a-15(e) and 15d-15(e) under the Securities Exchange Act of 1934) has been evaluated as of December 31, 2015. Based upon the evaluation, the CEO and CFO concluded that
as of December 31, 2015, the Companys disclosure controls and procedures were effective and designed to provide reasonable assurance that the information required to be disclosed by us in the reports that we file or submit under the
Securities Exchange Act of 1934, is recorded, processed, summarized and reported within the time periods specified in the SECs rules and forms and to ensure that information required to be disclosed in the reports that we file or submit under
the Securities Exchange Act of 1934 is accumulated and communicated to our management, including the CEO and CFO, as appropriate, to allow timely decisions regarding required disclosure.

Managements Report on Internal Control over Financial Reporting

Management is responsible for establishing and maintaining adequate internal control over financial reporting (as defined in Rules 13a-15(f)
and 15d-15(f) under the Securities Exchange Act of 1934) and for the assessment of the effectiveness of internal control over financial reporting. Internal control over financial reporting includes maintaining records, that, in reasonable detail,
accurately and fairly reflect our transactions; providing reasonable assurance that transactions are recorded as necessary for preparation of our financial statements; providing reasonable assurance that receipts and expenditures of Company assets
are made in accordance with management authorization; and providing reasonable assurance that unauthorized acquisition, use or disposition of Company assets that could have a material effect on our financial statements would be prevented or detected
on a timely basis. The Companys internal control over financial reporting is a process designed to provide reasonable, but not absolute, assurance regarding the reliability of financial reporting and the preparation of the consolidated
financial statements in accordance with generally accepted accounting principles. Because of its inherent limitations, internal control over financial reporting is not intended to provide absolute assurance that a misstatement of our financial
statements would be prevented or detected.

In connection with the preparation of the Companys annual consolidated financial
statements, management has undertaken an assessment of the effectiveness of the Companys internal control over financial reporting as of December 31, 2015, based on criteria established in the Internal-Control Integrated Framework
(2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission (the COSO Framework).

Based on this
assessment, management concluded that the Companys internal control over financial reporting was effective as of December 31, 2015.

Our consolidated financial statements have been audited by KPMG Accountants N.V., an independent registered public accounting firm, which has
issued an attestation report on the Companys internal control over financial reporting included elsewhere in this annual report on Form 20-F.

Changes in Controls and Procedures

Enhancements have been made during the period. There were no changes that occurred during the period covered by this report that have
materially affected, or are reasonably likely to materially affect, the Companys internal control over financial reporting.

the Securities and Exchange Commission, or the external auditor, for permissible non-audit services.

When engaging the external auditor
for permissible non-audit services (audit-related services, tax services, and all other services), pre-approval is obtained prior to the commencement of the services.

ITEM 16G: CORPORATE GOVERNANCE

Many of the corporate governance rules of the NYSE do not apply to the Company as a foreign private issuer; however, Rule 303A.11
requires foreign private issuers to describe significant differences between their corporate governance standards and the corporate governance standards applicable to U.S. companies listed on the NYSE. While the Companys management believes
that its corporate governance practices are similar in many respects to those of U.S. NYSE-listed companies and provide investors with protections that are comparable in many respects to those established by the NYSE, there is one key difference
which is described below.

Internal Audit Function

Under Section 303A.07 of the NYSE rules, a domestic listed company must have an internal audit function. In 2015, a formal internal audit
function was not in place.

Report of Independent Registered Public Accounting Firm

To: The Board of Directors and Shareholders of InterXion Holding N.V.

We have audited the accompanying consolidated statements of financial position of InterXion Holding N.V. and subsidiaries as of December 31, 2015, 2014, and
2013, and the related consolidated income statements and consolidated statements of comprehensive income, changes in shareholders equity, and cash flows for each of the years then ended. We also have audited InterXion Holding N.V.s
internal control over financial reporting as of December 31, 2015, based on criteria established in Internal Control  Integrated Framework (2013)issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO).
InterXion Holding N.V.s management is responsible for these consolidated financial statements, for maintaining effective internal control over financial reporting, and for its assessment of the effectiveness of internal control over financial
reporting, included in the accompanying Managements Report on Internal Control over Financial Reporting. Our responsibility is to express an opinion on these consolidated financial statements and an opinion on the Companys internal
control over financial reporting based on our audits.

We conducted our audits in accordance with the standards of the Public Company Accounting Oversight
Board (United States). Those standards require that we plan and perform the audits to obtain reasonable assurance about whether the financial statements are free of material misstatement and whether effective internal control over financial
reporting was maintained in all material respects. Our audits of the consolidated financial statements included examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements, assessing the accounting
principles used and significant estimates made by management, and evaluating the overall financial statement presentation. Our audit of internal control over financial reporting included obtaining an understanding of internal control over financial
reporting, assessing the risk that a material weakness exists, and testing and evaluating the design and operating effectiveness of internal control based on the assessed risk. Our audits also included performing such other procedures as we
considered necessary in the circumstances. We believe that our audits provide a reasonable basis for our opinions.

A companys internal control over
financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles.
A companys internal control over financial reporting includes those policies and procedures that (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the
assets of the company; (2) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the
company are being made only in accordance with authorizations of management and directors of the company; and (3) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the
companys assets that could have a material effect on the financial statements.

Because of its inherent limitations, internal control over financial
reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance
with the policies or procedures may deteriorate.

In our opinion, the consolidated financial statements referred to above present fairly, in all material
respects, the financial position of InterXion Holding N.V. and subsidiaries as of December 31, 2015, 2014 and 2013, and the results of their operations and their cash flows for each of the years then ended, in conformity with International Financial
Reporting Standards as issued by the International Accounting Standards Board. Also in our opinion, InterXion Holding N.V. maintained, in all material respects, effective internal control over financial reporting as of December 31, 2015, based
on criteria established in Internal Control  Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO).

NOTES TO THE 2015 CONSOLIDATED FINANCIAL STATEMENTS



|1 | The Company
|- | -----------

Interxion Holding N.V. (the Company) is domiciled in The
Netherlands. The Companys registered office is at Tupolevlaan 24, 1119 NX Schiphol-Rijk, The Netherlands. The consolidated financial statements of the Company for the year ended December 31, 2015 comprise the Company and its subsidiaries
(together referred to as the Group). The Group is a leading pan-European operator of carrier-neutral Internet data centers.

The financial statements, which were approved and authorized for issue by the Board of Directors on March 31, 2016, are subject to adoption by
the General Meeting of Shareholders.



|2 | Basis of preparation
|- | --------------------

Statement of compliance

The consolidated financial statements have been prepared in accordance with International Financial Reporting Standards (IFRSs),
effective as at December 31, 2015, as issued by the International Accounting Standards Board (IASB), and IFRS as adopted by the European Union, and also comply with the financial reporting requirements included in Part 9 of Book 2 of The
Netherlands Civil Code.

Basis of measurement

The Group prepared its consolidated financial statements on a going-concern basis and under the historical cost convention except for certain
financial instruments that have been measured at fair value.

Change in accounting policies

The Group has consistently applied the accounting policies set out below to all periods presented in these consolidated financial statements.
The standards below are applicable for financial statements as prepared after January 1, 2014, for IFRS as issued by the International Accounting Standards Board, and are effective for IFRS as endorsed by the European Union for periods ending after
January 1, 2015. For preparation of these financial statements, these standards have been early adopted under IFRS as endorsed by European Union.

Amendment to IAS 32  Financial instruments: Presentation

This amendment clarifies some of the requirements for offsetting financial assets and financial liabilities on the statement of financial
position. The amendment clarifies that the right of set-off must be available today, and is not contingent on a future event. Furthermore it clarifies that gross settlements with features that (i) eliminate credit and liquidity risk and (ii) process
receivables and payables in a single settlement process, are effectively equivalent to net settlements, and therefore satisfy the IAS 32 criterion. The amendment has no impact on the Groups assets and liabilities.

Amendment to IAS 36  Impairment of assets

This amendment has made small changes to the disclosures required by this standard when the recoverable amount is determined based on fair
value less costs of disposal. The amendment has impact when an impairment loss on non-financial assets is recognized or reversed. The amendment has no impact on the disclosure on the Groups assets and liabilities.

Amendment to IAS 39  Financial instruments: Recognition and measurement

The amendment relates to the novation of derivatives and the continuation of hedge accounting. This amendment considers legislative changes to
over-the-counter derivatives and the establishment of central counterparties. Under IAS 39 novation of derivatives to central counterparties would result in discontinuance of hedge accounting. The amendment provides relief from
discontinuing hedge accounting when novation of a hedging instrument meets specified criteria. The group has applied the amendment and there has been no significant impact on the group financial statements as a result.

IFRIC 21  Levies

The Group has adopted IFRIC 21  Levies with a date of January 1, 2014. IFRIC 21 sets out the accounting for an obligation to pay a levy
when that liability is within the scope of IAS 37 Provisions. The interpretation addresses what the obligating event is that gives rise to pay a levy and when a liability should be recognized. The Group is not currently subject to
significant levies so the impact on the Group is not significant.

Use of estimates and judgements

The preparation of financial statements in conformity with IFRS requires management to make judgements, estimates and assumptions that affect
the application of accounting policies and the reported amounts of assets, liabilities, income and expenses. Actual results may differ from these estimates, which together with underlying assumptions are reviewed on an ongoing basis. Revisions to
accounting estimates are recognized in the period in which the estimates are revised and in any future periods affected.

Judgements,
estimates and assumptions applied by management in preparing these financial statements are based on circumstances as at December 31, 2015 and Interxion operating as a stand-alone company.

In particular, information about significant areas of estimation uncertainty and critical judgments in applying accounting policies that have
the most significant effect on amounts recognized in the financial statements are discussed below:

Property, plant and equipment
depreciation (see also Note 11)  Estimated remaining useful lives and residual values are reviewed annually. The carrying values of property, plant and equipment are also reviewed for impairment, where there has been a triggering event, by
assessing the present value of estimated future cash flows and net realizable value compared with net book value. The calculation of estimated future cash flows and residual values is based on the Groups best estimates of future prices, output
and costs and is, therefore, subjective. Furthermore, the valuation of some of the assets under construction requires judgments which are related to the probability of signing lease contracts and obtaining planning permits.

In the fourth quarter of 2013, as part of the annual review of the estimated useful lives, we concluded that certain of our existing assets
are used longer than originally anticipated. The estimated useful lives of certain of our property, plant and equipment have, therefore, been extended. This change was accounted for as a change in accounting estimate on a prospective basis effective
October 1, 2013, under IAS 8 Change in Accounting Estimates. In the fourth quarter of 2013, depreciation expenses were approximately 2.0 million less than the prior quarter as a result of the changes in the estimated useful lives
of certain of our property, plant and equipment. On an annualized basis for the year ended December 31, 2013, the depreciation charges would have been approximately 8.0 million lower.

On December 13, 2013, we were awarded a permit by the Seine-St-Denis authorities to operate our PAR7 data center. On October 15, 2015, a
French administrative court ruled that local authorities failed to perform a sufficiently extensive study of the potential noise impact that operating the PAR7 data center could have on local residents and consequently the French administrative
court annulled the permit we received on December 13, 2013. The Seine-St-Denis authorities have since requested that we re-apply for a new permit. We have worked with the Seine-St-Denis authorities and we have obtained formal approval to continue to
operate the PAR7 data center during the application process, which we expect to conclude by the end of 2016. However, the lack of a permanent permit is not considered an impairment triggering event.

Intangible fixed assets amortization (see also Note 12) Estimated remaining useful lives and residual values are reviewed
annually. The carrying values of intangible fixed assets are also reviewed for impairment where there has been a triggering event by assessing the present value of estimated future cash flows and net realizable value compared with net book value.
The calculation of estimated future cash flows and residual values is based on the Groups best estimates of future prices, output and costs and is, therefore, subjective.

##### Table of Contents

Lease accounting (see also Note 23)  At inception or modification of an arrangement,
the Group determines whether such an arrangement is, or contains, a lease. Classification of a lease contract is based on the extent to which risks and rewards incidental to ownership of a leased asset lie with the lessor or the lessee. The
classification of lease contracts includes the use of judgements and estimates.

Provision for onerous lease contracts (see also Note
19)  A provision is made for the discounted amount of future losses that are expected to be incurred in respect of unused data center sites over the term of the leases. Where unused sites have been sublet, or partly sublet, management has
taken account of the contracted sublease income expected to be received over the minimum sublease term, which meets the Groups revenue recognition criteria in arriving at the amount of future losses.

Costs of site restoration (see also Note 25)  Liabilities in respect of obligations to restore premises to their original
condition are estimated at the commencement of the lease and reviewed yearly, based on the rent period, contracted extension possibilities and possibilities of lease terminations.

Deferred tax (see also Note 10)  Provision is made for deferred tax at the rates of tax prevailing at the period-end dates unless
future rates have been substantively enacted. Deferred tax assets are recognized where it is probable that they will be recovered based on estimates of future taxable profits for each tax jurisdiction. The actual profitability may be different
depending on local financial performance in each tax jurisdiction.

Share-based payments (see also Note 22)  The Group issues
equity-settled share-based payments to certain employees under the terms of the long-term incentive plans. The charges related to equity-settled share-based payments, options to purchase ordinary shares and restricted and performance shares, are
measured at fair value at the date of grant. The fair value at the grant date of options is determined using the Black Scholes model and is expensed over the vesting period. The fair value at grant date of the performance shares is determined using
the Monte Carlo model and is expensed over the vesting period. The value of the expense is dependent upon certain assumptions including the expected future volatility of the Groups share price at the date of grant and, for the performance
shares, the relative performance of the Groups share price compared to a group of peer companies.

Senior Secured Notes due 2020
(see also Note 20) The Senior Secured Notes due 2020 are valued at amortized cost. The Senior Secured Notes due 2020 indenture includes specific early redemption clauses. As part of the initial measurement of the amortized costs value of
the Senior Secured Notes due 2020 it is assumed that the Notes will be held to maturity. If an early redemption of all or part of the Notes is expected, the liability will be re-measured based on the original effective interest rate. The difference
between the liability, excluding a change in assumed early redemption and the liability, including a change in assumed early redemption, will go through the profit and loss.

Functional and presentation currency

These consolidated financial statements are presented in euro, the Companys functional and presentation currency. All information
presented in euros has been rounded to the nearest thousand, except when stated otherwise.



|3 | Significant accounting policies
|- | -------------------------------

Basis of consolidation

The consolidated financial statements incorporate the financial statements of the Company and all entities that are directly or indirectly
controlled by the Company. Subsidiaries are entities that are controlled by the Group. The Group controls an entity when it is exposed to, or has the right to, variable returns from its involvement with the entity and has the ability to affect those
returns through its power over the entity. The financial statements of subsidiaries are included in the consolidated financial statements from the date on which control commences until the date on which control ceases.

##### Table of Contents

The accounting policies set out below have been applied consistently by all subsidiaries to all
periods presented in these consolidated financial statements.

Loss of control

When the Group loses control over a subsidiary, the Company de-recognises the assets and liabilities of the subsidiary, any non-controlling
interests and the other components of equity related to the subsidiary. Any surplus or deficit arising on the loss of control is recognized in profit or loss.

Transactions eliminated on consolidation

Intercompany balances and transactions, and any unrealized income and expenses arising from intercompany transactions, are eliminated in
preparing the consolidated financial statements.

Subsidiaries

With the exception of Stichting Administratiekantoor Management Interxion, all the subsidiary undertakings of the Group as set out below are
wholly owned. Stichting Administratiekantoor is part of the consolidation based on the Groups control over the entity.

Foreign currency

Foreign currency transactions

The individual financial statements of each Group entity are presented in the currency of the primary economic environment in which
the entity operates (its functional currency). For the purpose of the consolidated financial statements, the results and the financial position of each entity are expressed in euros, which is the functional currency of the Company and the
presentation currency for the consolidated financial statements.

In preparing the financial statements of the individual entities,
transactions in foreign currencies other than the entitys functional currency are recorded at the rates of exchange prevailing at the dates of the transactions. At each balance sheet date, monetary assets and liabilities denominated in foreign
currencies are retranslated at the rates prevailing at the balance sheet date. Non-monetary items that are measured in terms of historical cost in a foreign currency are not retranslated. The income and expenses of foreign operations are translated
to euros at average exchange rates.

Foreign operations

For the purpose of presenting consolidated financial statements, the assets and liabilities of the Groups foreign operations are
expressed in euros using exchange rates prevailing at the balance sheet date. Income and expense items are translated at average exchange rates for the period. Exchange differences, if any, arising on net investments including receivables from or
payables to a foreign operation for which settlement is neither planned nor likely to occur, are recognized directly in the foreign currency translation reserve (FCTR) within equity. When control over a foreign operation is lost, in part or in full,
the relevant amount in the FCTR is transferred to profit or loss.

Borrowing costs

Borrowing costs directly attributable to the acquisition, construction or production of qualifying assets, which are assets that necessarily
take a substantial period of time to get ready for their intended use or sale, are added to the cost of those assets, until such time as the assets are substantially ready for their intended use or sale. All other borrowing costs are recognized in
profit or loss in the period in which they are incurred.

Borrowing costs are capitalized based on the effective interest rate of the
Senior Secured Notes.

Statement of cash flows

The consolidated statement of cash flows is prepared using the indirect method. The cash flow statement distinguishes between operating,
investing and financing activities.

Cash flows in foreign currencies are converted at the exchange rate at the dates of the transactions.
Currency exchange differences on cash held are separately shown. Payments and receipts of corporate income taxes and interest paid are included as cash flow from operating activities.

Financial instruments

Derivative financial instruments

Derivatives are initially recognized at fair value; any attributable transaction costs are recognized in profit and loss as they are incurred.
Subsequent to initial recognition, derivatives are measured at their fair value, and changes therein are generally recognized in profit and loss.

When a derivative is designated as a cash flow hedging instrument, the effective portion of changes in the fair value of the derivative is
recognized in other comprehensive income and accumulated in the hedging reserve. Any ineffective portion of changes in the fair value of the derivative is recognized immediately in profit or loss.

The amount accumulated in equity is retained in other comprehensive income and reclassified to the profit or loss in the same period, or
periods, during which the hedged item affects profit or loss.

If the hedging instrument no longer meets the criteria for hedge
accounting, expires, is sold, terminated or exercized, or the designation is revoked, hedge accounting is discontinued prospectively. If the forecast transaction is no longer expected to occur, the amount accumulated in equity is reclassified to
profit or loss.

Fair values are obtained from quoted market prices in active markets or, where an active market does not exist, by using
valuation techniques. Valuation techniques include discounted cash flow models.

Non-derivative financial instruments

Non-derivative financial instruments comprise trade and other receivables, cash and cash equivalents, loans and borrowings, and trade and other
payables.

Non-derivative financial instruments are recognized initially at fair value, net of any directly attributable transaction
costs. Subsequent to initial recognition, non-derivative financial instruments are measured at amortized cost using the effective interest method, less any impairment losses.

The Group de-recognizes a financial asset when the contractual rights to the cash flows from the asset expire, or it transfers the right to
receive the contractual cash flows in a transaction in which substantially all the risk and rewards of ownership of the financial asset are transferred. Any interest in such transferred financial assets that is created or retained by the Group is
recognized as a separate asset or liability.

Financial assets and liabilities are offset and the net amount presented in the statement of
financial position when, and only when, the Group has a legal right to offset the amounts and intends either to settle on a net basis or to realize the asset and settle the liability simultaneously.

Financial assets are designated as at fair value through profit and loss if the Group manages such investments and makes purchase and sale
decisions based on their fair value in accordance with the Groups risk management or investment strategy. Attributable transaction costs are recognized in profit and loss as incurred. Financial assets at fair value through profit and loss are
measured at fair value and changes therein, which takes into account any dividend income, are recognized in profit and loss.

The fair
values of investments in equity are determined with reference to their quoted closing bid price at the measurement date or, if unquoted, using a valuation technique.

Trade receivables and other current assets

Trade receivables and other current assets are recognized initially at fair value and subsequently measured at amortized cost using the
effective interest method, less provision for impairment.

A provision for impairment of trade receivables and other current assets is
established when there is objective evidence that the Group will not be able to collect all amounts due according to the original term of the receivables. Significant financial difficulties of the debtor, probability that the debtor will enter
bankruptcy or financial reorganisation, and default or delinquency in payments are considered indicators that the trade receivable is impaired.



F-12



---

##### Table of Contents

The amount of the provision is the difference between the assets carrying amount and the
present value of estimated future cash flows, discounted at the original effective interest rate. The carrying amount of the asset is reduced through the use of an allowance account, and the amount of the loss is recognized in the income statement.

When a trade receivable and other current asset is uncollectable, it is written off against the allowance account for trade receivables.
Subsequent recoveries of amounts previously written off are credited in the income statement.

Cash and cash equivalents

Cash and cash equivalents includes cash in hand, deposits held at call with banks and other short-term highly liquid investments with original
maturities of three months or less. Cash and cash equivalents, including short-term investments, is valued at face value, which equals its fair value.

Share capital

Ordinary shares are
classified as equity. Incremental costs directly attributable to the issue of ordinary shares and share options are recognized as a deduction from equity, net of any tax effects.

Trade payables and other current liabilities

Trade payables and other current liabilities are recognized initially at fair value and subsequently measured at amortized cost using the
effective interest method.

Property, plant and equipment

Property, plant and equipment are measured at cost less accumulated depreciation and accumulated impairment losses.

Cost includes expenditures that are directly attributable to the acquisition or construction of the asset and comprises purchase cost,
together with the incidental costs of installation and commissioning. These costs include external consultancy fees, capitalized borrowing costs, rent and associated costs attributable to bringing the assets to a working condition for their intended
use and internal employment costs that are directly and exclusively related to the underlying asset. In case of operating leases where it is probable that the lease contract will not be renewed, the cost of self-constructed assets includes the
estimated costs of dismantling and removing the items and restoring the site on which they are located.

When parts of an item of
property, plant and equipment have different useful lives, they are accounted for as separate items (major components) of property, plant and equipment.

Gains and losses on disposal of an item of property, plant and equipment are determined by comparing the proceeds from disposal with the
carrying amount of property, plant and equipment and are recognized within income.

The cost of replacing part of an item of property,
plant and equipment is recognized in the carrying amount of the item if it is probable that the future economic benefits embodied within the part will flow to the Group and its cost can be measured reliably. The carrying amount of the replaced part
is de-recognized. The costs of the day-to-day servicing of property, plant and equipment are recognized in profit or loss as incurred.

Depreciation is calculated from the date an asset becomes available for use and is depreciated on a straight-line basis over the estimated
useful life of each part of an item of property, plant and equipment. Leased assets are depreciated on the same basis as owned assets over the shorter of the lease term and their useful lives. The principal periods used for this purpose are:



|                                         |  |                
|---------------------------------------- |  | ---------------
|Data center freehold land                |  | Not depreciated
|                                         | 
|Data center buildings                    |  | 15-30 years    
|                                         | 
|Data center infrastructure and equipment |  | 5-20 years     
|                                         | 
|Office equipment and other               |  | 3-15 years

Depreciation methods, useful lives and residual values are reviewed annually.

In the fourth quarter of 2013, as part of the annual review of the estimated useful lives, we concluded that certain of our existing assets
are used longer than originally anticipated. The estimated useful lives of certain of our property, plant and equipment have, therefore, been extended. This change was accounted for as a change in accounting estimate on a prospective basis effective
October 1, 2013 under IAS 8 Change in Accounting Estimates. In the fourth quarter of 2013, depreciation expenses were approximately 2.0 million less than the prior quarter as a result of the changes in the estimated useful
lives of certain of our property, plant and equipment. On an annualized basis for the year ended December 31, 2013, the depreciation charges would have been approximately 8.0 million lower.

Data center freehold land consists of the land owned by the Company and land leased by the Company under finance lease agreements. The data
center buildings consist of the core and shell in which we have constructed a data center. Data center infrastructure and equipment comprises of data center structures, leasehold improvements, data center cooling and power infrastructure, including
infrastructure for advanced environmental controls such as ventilation and air conditioning, specialized heating, fire detection and suppression equipment and monitoring equipment. Office equipment and other comprised of office leasehold
improvements and office equipment consisting of furniture, computer equipment and software.

Intangible assets

Intangible assets represent power grid rights, software and other intangible assets, and are recognized at cost less accumulated amortization
and accumulated impairment losses. Other intangible assets principally consist of lease premiums (paid in addition to obtain rental contracts).

Software includes development expenditure, which is capitalized only if development costs can be measured reliably, the product or process is
technically and commercially feasible, future economic benefits are probable, and the Group intends to and has sufficient resources to complete development and to use the asset. The expenditure capitalized includes the cost of material, services and
direct labour costs that are directly attributable to preparing the asset for its intended use.

Amortization is calculated on a
straight-line basis over the estimated useful lives of the intangible asset. Amortization methods, useful lives and residual values are reviewed annually.

The estimated useful lives are:



|                       |  |             |  | 
|---------------------- |  | ----------- |  | 
|    Power grid rights |  | 1015 years |  | 
|                       |  |            
|    Software          |  | 35 years   |  | 
|                       |  |            
|    Other             |  | 312 years  |  | 

Impairment of non-financial assets

The carrying amounts of the Groups non-financial assets, other than deferred tax assets, are reviewed at each reporting date to determine
whether there is any indication of impairment. If any such indication exists, then the assets recoverable amount is estimated. For intangible assets that are not yet available for use, the recoverable amount is estimated at each reporting
date.

The recoverable amount of an asset or cash-generating unit is the greater of either its value in use or its fair value less costs
to sell. In assessing value in use, the estimated future cash flows are discounted to their present value using a pre-tax discount rate that reflects current market assessments of the time value of money and the risks specific to the asset. For the
purpose of impairment testing, assets are grouped together into the smallest group of assets that generates cash inflows from continuing use that are largely independent of the cash inflows of other assets or groups of assets (the
cash-generating unit).

##### Table of Contents

Considering the Company manages its data centers by country, and, given the data center campus
structures, the financial performance of data centers within a country is highly inter-dependent, the Company has determined that the cash-generating unit for impairment-testing purposes should be the group of data centers per country, unless
specific circumstances would indicate that a single data center is a cash-generating unit.

An impairment loss is recognized if the
carrying amount of an asset or its cash-generating unit exceeds its estimated recoverable amount. Impairment losses are recognized in profit or loss. Impairment losses recognized in respect of cash-generating units are to reduce the carrying amount
of the assets in the unit (group of units) on a pro-rata basis.

Impairment losses recognized in prior periods are assessed at each
reporting date for any indications that the loss has decreased or no longer exists. An impairment loss is reversed if there has been a change in the estimates used to determine the recoverable amount. An impairment loss is reversed only to the
extent that the assets carrying amount does not exceed the carrying amount that would have been determined, net of depreciation or amortization, if no impairment loss had been recognized.

Borrowings

Borrowings are recognized
initially at fair value, net of transaction costs incurred. Borrowings are subsequently stated at amortized cost; with any difference between the proceeds (net of transaction costs) and the redemption value recognized in the income statement over
the period of the borrowings using the effective interest method.

Borrowings are classified as current liabilities unless the Group has
an unconditional right to defer settlement of the liability for at least 12 months after the balance sheet date. The Group de-recognizes a borrowing when its contractual obligations are discharged, cancelled or expired.

As part of the initial measurement of the amortized costs value of the Senior Secured Notes due 2020 it is assumed that the Notes will be held
to maturity. If an early redemption of all or part of the Notes is expected the liability will be re-measured based on the original effective interest rate. The difference between the liability, excluding a change in assumed early redemption and the
liability, including a change in assumed early redemption, will be recognized in profit and loss.

Provisions

A provision is recognized in the statement of financial position when the Group has a present legal or constructive obligation as a result of a
past event; it is probable that an outflow of economic benefits will be required to settle the obligation and the amount can be estimated reliably. Provisionsare determined by discounting the expected future cash flows at a pre-tax rate that
reflects current market assessments of the time value of money and, where appropriate, the risks specific to the liability. The discount rate arising on the provision is amortized in future years through interest.

A provision for site restoration is recognized when costs for restoring leasehold premises to their original condition at the end of the lease
are probable to be incurred and it is possible to make an accurate estimate of these costs. The discounted cost of the liability is included in the related assets and is depreciated over the remaining estimated term of the lease. If the likelihood
of this liability is estimated to be possible, rather than probable, it is disclosed as a contingent liability in Note 25.

A provision
for onerous lease contracts is recognized when the expected benefits to be derived by the Group from a contract are lower than the unavoidable cost of meeting its obligations under the contract. The provision is measured at the discounted amount of
future losses expected to be incurred in respect of unused data center sites over the term of the leases. Where unused sites have been sublet or partly sublet, management has taken account of the contracted sublease income expected to be received
over the minimum sublease term, which meets the Groups revenue recognition criteria in arriving at the amount of future losses. Before a provision is established, the Group recognises any impairment loss on the assets associated with that
contract.

Leases

Leases, in which the Group assumes substantially all the risks and rewards of ownership, are classified as finance leases. On initial
recognition, the leased asset is measured at an amount equal to the lower of either its fair value or the present value of the minimum lease payments. Subsequent to initial recognition, the asset is accounted for in accordance with the accounting
policy applicable to that asset. The finance lease obligations are presented as part of the long term liabilities and, as far as amounts need to be repaid within one year, as part of current liabilities.

Other leases are operating leases and the leased assets are not recognized on the Groups statement of financial position. Payments made
under operating leases are recognized in the income statement, or capitalized during construction, on a straight-line basis over the term of the lease. Lease incentives received are recognized as an integral part of the total lease expense, over the
term of the lease.

Minimum finance lease payments are apportioned between the finance charge and the reduction of the outstanding
liability. The finance charge is allocated to each period during the lease term so as to produce a constant periodic rate of interest on the remaining balance of the liability.

At inception or modification of an arrangement, the Group determines whether such an arrangement is, or contains, a lease. This will be the
case if the following two criteria are met:



| |  |  | the fulfilment of the arrangement is dependent on the use of a specific asset or assets; and
| | - |  | --------------------------------------------------------------------------------------------



| |  |  | the arrangement contains the right to use an asset.
| | - |  | ---------------------------------------------------

For leased properties on which our data centers are
located, we generally seek to secure property leases for terms of 20 to 25 years. Where possible, we try to mitigate the long-term financial commitment by contracting for initial lease terms for a minimum period of 10 to 15 years with the option for
us to either (i) extend the leases for additional five-year terms or (ii) terminate the leases upon expiration of the initial 10 to 15 year term. Our leases generally have consumer price index based annual rent increases over the full term of the
lease. Certain of our leases contain options to purchase the asset.

Segment reporting

The segments are reported in a manner consistent with internal reporting provided to the chief operating decision-maker, identified as the
Board of Directors. There are two segments: the first segment is France, Germany, The Netherlands and the United Kingdom(the Big4), the second segment is Rest of Europe, which comprises Austria, Belgium, Denmark,
Ireland, Spain, Sweden and Switzerland. Shared expenses such as corporate management, general and administrative expenses, loans and borrowings and related expenses and income tax assets and liabilities are stated in Corporate and other. The
Big4 and Rest of Europe are different segments as management believes that the Big4 countries represent the largest opportunities for Interxion, from market trends and growth perspective to drive the development its communities of interest
strategy within customer segments and the attraction of magnetic customers. As a result over the past three years we have invested between 65-69% of our capital expenditures in the Big4 segment while revenues constituted an average of 63% of total
over the same period.

Segment results, assets and liabilities include items directly attributable to a segment as well as those that can
be allocated on a reasonable basis. Unallocated items presented as Corporate and other principally comprise loans and borrowings and related expenses; corporate assets and expenses (primarily the Companys headquarters); and income tax
assets and liabilities.

Segment capital expenditure is defined as the net cash outflow during the period to acquire property, plant and
equipment, and intangible assets other than goodwill.

EBITDA and Adjusted EBITDA, as well as recurring revenue, are additional indicators of our
operating performance, and are not required by or presented in accordance with, IFRS. EBITDA is defined as operating profit plus depreciation, amortization and impairment of assets. We define Adjusted EBITDA as EBITDA adjusted to exclude share-based
payments, M&A transaction costs, increase/(decrease) in provision for onerous lease contracts, M&A transaction break fee income, and income from sub-leases of unused data center sites. We present EBITDA and Adjusted EBITDA as additional
information because we understand that they are measures used by certain investors and because they are used in our financial covenants in our 100 million Revolving Facility Agreement and 475 million 6.00% Senior Secured Notes due 2020.
Other companies may, however, present EBITDA and Adjusted EBITDA differently than we do. EBITDA and Adjusted EBITDA are not measures of financial performance under IFRS and should not be considered as an alternative to operating profit or as a
measure of liquidity or an alternative to net income as indicators of our operating performance or any other measure of performance derived in accordance with IFRS.

This information, provided to the chief operating decision-maker, is disclosed to permit a more complete analysis of our operating
performance. Exceptional items are those significant items that are separately disclosed by virtue of their size, nature or incidence to enable a full understanding of the Groups financial performance.

Revenue recognition

Revenue is
recognized when it is probable that future economic benefits will flow to the Group and that these benefits, together with their related costs, can be measured reliably. Revenue is measured at the fair value of the consideration received or
receivable taking into account any discounts or volume rebates.

The Group reviews transactions for separately identifiable components
and, if necessary, applies individual recognition treatment, revenues are allocated to separately identifiable components based on their relative fair values.

The Group earns colocation revenue as a result of providing data center services to customers at its data centers. Colocation revenue and
lease income are recognized in profit or loss on a straight-line basis over the term of the customer contract. Incentives granted are recognized as an integral part of the total income, over the term of the customer contract. Customers are usually
invoiced quarterly in advance and income is recognized on a straight-line basis over the quarter. Initial setup fees payable at the beginning of customer contracts are deferred at inception and recognized in the income statement on a straight-line
basis over the initial term of the customer contract. Power revenue is recognized based on customers usage.

Other services revenue,
including managed services, connectivity and customer installation services including equipment sales are recognized when the services are rendered. Certain installation services and equipment sales, which by their nature have a non-recurring
character, are presented as non-recurring revenues and are recognized on delivery of service.

Deferred revenues relating to invoicing in
advance and initial setup fees are carried on the statement of financial position as part of trade payables and other liabilities. Deferred revenues due to be recognized after more than one year are held in non-current liabilities.

Cost of sales

Cost of sales consists
mainly of rental costs for the data centers and offices, power costs, maintenance costs relating to the data center equipment, operation and support personnel costs and costs related to installations and other customer requirements. In general,
maintenance and repairs are expensed as incurred. In cases where maintenance contracts are in place, the costs are recorded on a straight-line basis over the contractual period.

Sales and marketing costs

The operating
expenses related to sales and marketing consist of costs for personnel (including sales commissions), marketing and other costs directly related to the sales process. Costs of advertising and promotion are expensed as incurred.

##### Table of Contents

General and administrative costs

General and administrative costs include depreciation expenses and are expensed as incurred.

Employee benefits

Defined contribution pension plans

A defined contribution pension plan is a post-employment plan under which an entity pays fixed contributions into a separate entity
and has no legal or constructive obligation to pay further amounts. Obligations for contributions to defined contribution plans are recognized as an employee benefit expense in the income statement in the periods during which the related services
are rendered by employees. Prepaid contributions are recognized as an asset to the extent that a cash refund or a reduction in future payments is available. Contributions to a defined contribution plan that are due more than 12 months after the end
of the period in which the employees render the service are discounted to their present value.

Termination benefits

Termination benefits are recognized as an expense when the Group is demonstrably committed, without realistic possibility of withdrawal, to a
formal detailed plan to either terminate employment before the normal retirement date, or to provide termination benefits as a result of an offer made to encourage voluntary redundancy. Termination benefits for voluntary redundancy are recognized as
an expense if the Group has made an offer of voluntary redundancy, it is probable that the offer will be accepted, and the number of acceptances can be estimated reliably. If benefits are payable more than 12 months after the reporting date, they
are discounted to their present value.

Share-based payments

The long-term incentive programme enables Group employees to earn and/or acquire shares of the Group. The fair value at the date of grant to
employees of share options, as determined using the Black Scholes model for options and the Monte Carlo model for the performance shares, is recognized as an employee expense, with a corresponding increase in equity, over the period that the
employees become unconditionally entitled to the options and/or shares. The amount recognized as an expense is adjusted to reflect the actual number of share options, restricted and performance shares that vest. Restricted shares are valued based on
the market value at grant date.

Finance income and expense

Finance expense comprises interest payable on borrowings calculated using the effective interest rate method, gains on financial assets
recognized at fair value through profit and loss and foreign exchange gains and losses. Borrowing costs directly attributable to the acquisition or construction of data center assets, which are assets that necessarily take a substantial period of
time to get ready for their intended use, are added to the costs of those assets, until such time as the assets are ready for their intended use.

Interest income is recognized in the income statement as it accrues, using the effective interest method. The interest expense component of
finance lease payments is recognized in the income statement using the effective interest rate method.

Foreign currency gains and losses
are reported on a net basis, as either finance income or expenses, depending on whether the foreign currency movements are in a net gain or a net loss position.

Income tax

Income tax on the profit or
loss for the year comprises current and deferred tax. Income tax is recognized in the income statement except to the extent that it relates to items recognized directly in equity, in which case it is recognized in equity.



F-18

##### Table of Contents

Current tax is the expected tax payable on the taxable income for the year, using tax rates
enacted or substantially enacted at the balance sheet date, and any adjustment to tax payable in respect of previous years.

Deferred tax
is recognized in respect of temporary differences between the carrying amount of assets and liabilities for financial reporting purposes and the amounts used for taxation purposes. The following temporary differences are not provided for: the
initial recognition of assets or liabilities that affect neither accounting nor taxable profit, and differences relating to investments in subsidiaries to the extent that they will probably not reverse in the foreseeable future. The amount of
deferred tax provided is based on the expected manner of realization or settlement of the carrying amount of assets and liabilities, using tax rates enacted or substantively enacted at the balance sheet date that are expected to be applied to
temporary differences when they reverse or loss carry forwards when they are utilized.

A deferred tax asset is also recognized for unused
tax losses and tax credits. A deferred tax asset is recognized only to the extent that it is probable that future taxable profits will be available against which the asset can be utilized. Deferred tax assets are reduced to the extent that it is no
longer probable that the related tax benefit will be realized.

Additional income taxes that arise from the distribution of dividends are
recognized at the same time as the liability to pay the related dividend.

In determining the amount of current and deferred tax the
Company takes into account the impact of uncertain tax positions and whether additional taxes and interest may be due. The Company believes that its accruals for tax liabilities are adequate for all open tax years based on its assessment of many
factors, including interpretations of tax law and prior experience. This assessment relies on estimates and assumptions and may involve a series of judgements about future events. New information may become available that causes the Company to
change its judgement regarding the adequacy of existing tax liabilities; such changes to tax liabilities will have an impact on tax expense in the period that such a determination is made.

Deferred tax assets and liabilities are offset if there is a legally enforceable right to offset current tax liabilities and assets, and they
relate to taxes levied by the same tax authority on the same taxable entity, or on different tax entities, but they intend to settle current tax liabilities and assets on a net basis of their tax assets and liabilities will be realized
simultaneously.

Earnings per share

The Group presents basic and diluted earnings per share (EPS) data for its ordinary shares. Basic EPS is calculated by dividing the profit or
loss attributable to ordinary and preference shareholders of the Company by the weighted average number of ordinary shares outstanding during the year. Diluted EPS is determined by adjusting the profit or loss attributable to ordinary shareholders
and the weighted average number of ordinary outstanding for the effects of all dilutive potential ordinary shares, which comprise the share options granted.

|4 | Financial risk management
|- | -------------------------

Overview

The Group has exposure to the following risks from its use of financial instruments:

Credit risk

Liquidity risk

Market risk

Other price risks

This note presents information about the Groups exposure to each of the above risks, the Groups goals, policies and processes for
measuring and managing risk, and its management of capital. Further quantitative disclosures are included throughout these consolidated financial statements.

The Board of Directors has overall responsibility for the oversight of the Groups risk management framework.

The Group continues developing and evaluating the Groups risk management policies with a view to identifying and analyzing the risks
faced, to setting appropriate risk limits and controls, and to monitoring risks and adherence to limits. Risk management policies and systems are reviewed regularly to reflect changes in market conditions and the Groups activities. The Group,
through its training and management standards and procedures, aims to develop a disciplined and constructive control environment in which all employees understand their roles and obligations.

The Board of Directors oversees the way management monitors compliance with the Groups risk management policies and procedures and
reviews the adequacy of the risk management framework in relation to the risks the Group faces.

Credit risk

Credit risk is the risk of financial loss to the Group if a customer, bank or other counterparty to a financial instrument were to fail to meet
its contractual obligations. It principally arises from the Groups receivables from customers. The Groups most significant customer, which is serviced from multiple locations and under a number of service contracts, accounted for 11% of
recurring revenues in 2015, and for less than 10% in 2014 and 2013. In 2015 this customer accounted for 15% of recurring revenues in the Big4 segment, and for 5% of recurring revenues in the Rest of Europe segment.

Trade and other receivables

The
Groups exposure to credit risk is mainly influenced by the individual characteristics of each customer. The demographics of the Groups customer base, including the default risk of the industry and the country in which customers operate,
has less of an influence on credit risk.

The Group has an established credit policy under which each new customer is analyzed
individually for creditworthiness before it begins to trade with the Group. If customers are independently rated, these ratings are used. If there is no independent rating, the credit quality of the customer is analyzed taking its financial
position, past experience and other factors into account.

The Groups standard terms require contracted services to be paid in
advance of these services being delivered. Next to the standard terms the Group provided service fee holidays in relation to our long-term customer contracts, for which an accrued revenue balance is accounted for. In the event that a customer fails
to pay amounts that are due, the Group has a clearly defined escalation policy that can result in a customers access to their equipment being denied or service to the customer being suspended.



F-20

##### Table of Contents

In 2015, 94% (2014: 94% and 2013: 95%) of the Groups revenue was derived from contracts
under which customers paid an agreed contracted amount, including power on a regular basis (usually monthly or quarterly) or from deferred initial setup fees paid at the outset of the customer contract.

As a result of the Groups credit policy and the contracted nature of the revenues, losses have occurred infrequently (see Note 21). The
Group establishes an allowance that represents its estimate of potential incurred losses in respect of trade and other receivables. This allowance is entirely composed of a specific loss component relating to individually significant exposures.

Bank counterparties

The Group has
certain obligations under the terms of its revolving loan agreement and Senior Secured Notes which limit disposal with surplus cash balances. The Group monitors its cash position, including counterparty and term risk, daily.

Guarantees

Certain of our subsidiaries
have granted guarantees to our lending banks in relation to our facilities. The Company grants rent guarantees to landlords of certain of the Groups property leases (see Note 25).

Liquidity risk

Liquidity risk is the
risk that the Group will not be able to meet its financial obligations as they fall due. The Groups approach to managing liquidity is to ensure, as far as possible, that it will always have sufficient liquidity to meet its liabilities when
due, under both normal and stressed conditions, without incurring unacceptable losses or risking damage to the its reputation or jeopardizing its future.

The majority of the Groups revenues and operating costs are contracted, which assists it in monitoring cash flow requirements, which is
done on a daily and weekly basis. Typically, the Group ensures that it has sufficient cash on demand to meet expected normal operational expenses, including the servicing of financial obligations, for a period of 60 days; this excludes the potential
impact of extreme circumstances, such as natural disasters, that cannot reasonably be predicted.

All significant capital expansion
projects are subject to formal approval by the Board of Directors, and material expenditure or customer commitments are only made once the management is satisfied that the Group has adequate committed funding to cover the anticipated expenditure
(see Note 23).

Senior Secured Notes

On July 3, 2013, the Company issued an aggregate principal amount of 325 million 6.00% Senior Secured Notes due 2020 (the Senior
Secured Notes due 2020). The net proceeds of the offering were used to purchase all of the 260 million Senior Secured Notes due 2017, which were tendered in the offer for those notes and to redeem the 260 million Senior Secured
Notes due 2017 which remained outstanding following the expiration and settlement of the tender offer and consent solicitation, to pay all related fees, expenses and premiums and for other general corporate purposes.

The Senior Secured Notes due 2020 are governed by an indenture dated July 3, 2013, between the Company, as issuer, and The Bank of New York
Mellon, London Branch as Trustee. The indenture contains customary restrictive covenants, including but not limited to limitations or restrictions on our ability to incur debt, grant liens, make restricted payments and sell assets. The restrictive
covenants are subject to customary exceptions and are governed by a consolidated fixed charge ratio (Adjusted EBITDA to Finance Charges) to exceed 2.00 and a consolidated senior leverage ratio (Total Net Debt to Pro-forma EBITDA) not to exceed 4.00.
In addition, the aggregate of any outstanding debt senior to our Senior Secured Notes should not exceed 100 million.

The
obligations under the Senior Secured Notes due 2020 are guaranteed by certain of the Companys subsidiaries.

##### Table of Contents

On April 29, 2014, the Company completed the issuance of 150.0 million aggregate principal
amount of 6.00% Senior Secured Notes due 2020 (the Additional Notes). The net proceeds of the offering amount to 157.9 million, net of offering fees and expenses of 2.3 million. The net proceeds reflect the issuance of the
Additional Notes at a premium at 106.75 and net of offering fees and expenses. The Additional Notes, which are guaranteed by certain subsidiaries of the Company, were issued under the indenture pursuant to which, on July 3, 2013, the Company issued
325.0 million in aggregate principal amount of 6.00% Senior Secured Notes due 2020.

Senior Secured Facility

On April 14, 2014, the Company entered into a senior secured facility agreement (the Senior Secured Facility Agreement) between,
among others, the Issuer, Barclays Bank PLC and ABN AMRO Bank N.V. as lenders and Barclays Bank PLC as agent (the Agent) and security trustee, pursuant to which a 100.0 million senior secured term facility (the Senior Secured
Facility) was made available to the Company.

Following the successful closing of the offering of Additional Notes (as defined and
described in the preceding paragraph), the Company terminated the 100.0 million Senior Secured Facility Agreement. No amounts had been drawn under the Senior Secured Facility Agreement. However, the deferred financing fees amounting to
0.6 million were written off in April 2014 in connection with the termination of the Secured Senior Facility Agreement.

Revolving Facility

On June 17, 2013, the Company entered into a new 100 million Revolving Facility Agreement with ABN AMRO Bank N.V., Barclays Bank
PLC, Citigroup Global Markets Limited, Credit Suisse AG, Banc of America Securities Limited, as arrangers, the lenders thereunder, Barclays Bank PLC, as agent and Barclays Bank PLC as security trustee. This new 100 million Revolving Facility
Agreement replaced the 60 million revolving facility agreement.

On July 3, 2013, in connection with the issuance of the 325
million Senior Secured Notes due 2020, all conditions precedent to the utilization of this Revolving Facility Agreement were satisfied.

On July 28, 2014, Interxion Holding N.V. received consent from the lenders under its 100 million revolving facility to decrease the net
assets guarantor coverage from 70% to 65% for a one-year period with effect from June 30, 2014. The Company has not been in breach of any covenants during the year.

As of December 2014, following the addition of Interxion Österreich GmbH as obligor to the group of guarantors, the net assets guarantor
coverage exceeded 70%.

The net asset guarantor coverage is calculated as the aggregate net assets of the guarantors under the revolving
facility (calculated on an unconsolidated basis and excluding all intragroup items and investments in subsidiaries of any member of the Group) to consolidated net assets of the Group.

The Revolving Facility Agreement also requires the Company to maintain a specified financial ratio. The restrictive covenants are subject to
customary exceptions including, in relation to the incurrence of additional debt, a consolidated fixed charge ratio (calculated as a ratio of adjusted EBITDA to consolidated interest expense) to exceed 2.00 to 1.00 on a pro forma basis for the four
full fiscal quarters (taken as one period) for which financial statements are available immediately preceding the incurrence of such debt and, if such debt is senior debt, a consolidated senior leverage ratio (calculated as a ratio of outstanding
senior debt net of cash and cash equivalents of the Company and its restricted subsidiaries (on a consolidated basis) to pro forma adjusted EBITDA) to be less than 4.00 to 1.00 on a pro forma basis for the four full fiscal quarters (taken as one

The Revolving Facility Agreement also includes a leverage ratio financial covenant (tested on a
quarterly basis) requiring total net debt (calculated as a ratio to pro forma EBITDA) not to exceed a leverage ratio of 4.00 to 1.00. In addition, the Company must ensure, under the Revolving Facility Agreement, that the guarantors represent a
certain percentage of adjusted EBITDA of the Group as a whole and a certain percentage of the consolidated net assets of the Group as a whole. Our ability to meet these covenants may be affected by events beyond our control and, as a result, we
cannot assure you that we will be able to meet the covenants. In the event of a default under the Revolving Facility Agreement, the lenders could terminate their commitments and declare all amounts owed to them to be due and payable. Borrowings
under other debt instruments that contain cross acceleration or cross default provisions, including the Senior Secured Notes, may as a result also be accelerated and become due and payable.

The breach of any of these covenants by the Company or the failure by the Company to maintain its leverage ratio could result in a default
under the Revolving Facility Agreement. As of December 31, 2015, the Company was in compliance with all covenants in the Revolving Facility Agreement. In addition, the Company does not anticipate any such breach or failure and believes that its
ability to borrow funds under the Revolving Facility Agreement will not be adversely affected by the covenants in the next 12 months.

As
at December 31, 2015, the revolving facility agreement remained undrawn. The Companys consolidated fixed charge ratio stood at 5.14 and the net debt ratio/consolidated senior leverage ratio stood at 2.94.

Market risk

Currency risk

The Group is exposed to currency risk on sales, purchases and borrowings that are denominated in a currency other than the respective
functional currencies of Group entities, primarily the euro, but also pounds sterling (GBP), Swiss francs (CHF), Danish kroner (DKK) and Swedish kronor (SEK). The currencies in which these transactions are primarily denominated are EUR, GBP, CHF,
DKK, SEK and USD.

Historically, the revenues and operating costs of each of the Groups entities have provided an economic hedge
against foreign currency exposure and have not required foreign currency hedging.

It is anticipated that a number of capital expansion
projects will be funded in a currency that is not the functional currency of the entity in which the associated expenditure will be incurred. In the event that this occurs and is material to the Group, the Group will seek to implement an appropriate
hedging strategy.

The majority of the Groups borrowings are euro denominated and the Company believes that the Interest on these
borrowings will be serviced from the cash flows generated by the underlying operations of the Group, the functional currency of which is the euro. The Groups investments in subsidiaries are not hedged.

Interest rate risk

Following the issue
of 6.00% Senior Secured Notes due 2020, the Group is not exposed to significant variable interest rate expense for borrowings.

On
November 5, 2012, the Company secured a five-year mortgage 10 million on the AMS6 data center property. The loan is subject to a floating interest rate of EURIBOR plus an individual margin of 275 basis points per annum. Interest is due
quarterly in arrears.

On January 18, 2013, the Group completed two mortgage financings totalling 10 million. The loans are secured
by mortgages, on the PAR3 land owned by Interxion Real Estate II Sarl, and the PAR5 land owned by Interxion Real Estate III Sarl, pledges on the lease agreements, and are guaranteed by Interxion France SAS. The mortgages have a maturity of fifteen
years and have a variable interest rate based on EURIBOR plus an individual margin ranging from 240 to 280 basis points. The interest rates have been fixed through an interest rate swap for 75% of the principal outstanding amount for a period of 10
years.

On June 26, 2013, the Group completed a 6 million mortgage financing. The loan is secured by a mortgage on the AMS3 property
owned by Interxion Real Estate V B.V. and a pledge on the lease agreement. The mortgage loan has a variable interest rate based on EURIBOR plus 275 basis points.

On April 1, 2014, the Group completed a 9.2 million mortgage financing. The facility is secured by a mortgage on the data center
property in Zaventem (Belgium), which was acquired by Interxion Real Estate IX N.V. on January 9, 2014, a pledge on the lease agreement, and is guaranteed by Interxion Real Estate Holding B.V. The mortgage loan has a variable interest rate based on
EURIBOR plus 200 basis points.

On October 13, 2015, the Group completed a 15.0 million mortgage financing. The facility is secured
by a mortgage on the real estate property in Germany, which is owned by Interxion Real Estate I B.V. and a pledge on the lease agreement. The facility has a maturity of five years and has a variable interest rate based on EURIBOR plus 225 basis
points.

As at December 31, 2015, on the Revolving Facility Agreement the interest payable on EUR amounts drawn would be at the rate of
EURIBOR plus 350 basis points and for GBP amounts drawn the interest payable would be LIBOR plus 350 basis points. The Revolving Facility Agreement was fully undrawn as at December 31, 2015.

Other risks

Price risk

There is a risk that changes
in market circumstances, such as strong unanticipated increases in operational costs, construction of new data centers or churn in customer contracts, will negatively affect the Groups income. Customers individually have medium-term contracts
that require notice prior to termination. The objective of market risk management is to manage and control market risk exposures within acceptable parameters, while optimizing the return.

The Group is a significant user of power and has exposure to increases in power prices. It uses independent consultants to monitor price
changes in electricity and seeks to negotiate fixed-price term agreements with the power supply companies, not more than for own use, where possible. The risk to the Group is mitigated by the contracted ability to recover power price increases
through adjustments in the pricing for power services.

Capital management

The Group has a capital base comprising its equity, including reserves, Senior Secured Notes, mortgage loan, finance leases and committed debt
facilities. It monitors its solvency ratio, financial leverage, funds from operations and net debt with reference to multiples of its previous twelve months Adjusted EBITDA levels. The Companys policy is to maintain a strong capital base
and access to capital in order to sustain the future development of the business and maintain shareholders, creditors and customers confidence.

The principal use of capital in the development of the business is through capital expansion projects for the deployment of further equipped
space in new and existing data centers. Major capital expansion projects are not started unless the Company has access to adequate capital resources at the start of the project to complete the project, and they are evaluated against target internal
rates of return before approval. Capital expansion projects are continually monitored before and after completion.

There were no changes
in the Groups approach to capital management during the year.



|5 | Information by segment
|- | ----------------------

Operating segments are to be identified on the basis of internal
reports about components of the Group that are regularly reviewed by the chief operating decision maker in order to allocate resources to the segments and to assess their performance. Management monitors the operating results of its business units
separately for the purpose of making decisions about performance assessments.

There are two segments: the first is The Big4 which
comprise of France, Germany, The Netherlands and the United Kingdom; the second is Rest of Europe, which comprises Austria, Belgium, Denmark, Ireland, Spain, Sweden and Switzerland. Shared expenses, such as corporate management,
general and administrative expenses, loans and borrowings, and related expenses and income tax assets and liabilities, are stated in Corporate and other.

The performance of the operating segments is primarily based on the measures of revenue, EBITDA and Adjusted EBITDA. Other information
provided, except as noted below, to the Board of Directors is measured in a manner consistent with that in the financial statements.

The
geographic information analyzes the Groups revenues and non-current assets by the Companys country of domicile and other countries. In presenting the geographic information both revenue and assets have been based on their geographic
location. The Netherlands is the country of domicile which reported revenues amounting to 65,225,000 (2014: 57,834,000; 2013: 50,569,000) and non-current assets (excluding DTA) amounting to 235,270,000 (2014:
230,404,000; 2013: 180,409,000).

The Group operates a defined contribution scheme for most of its employees. The contributions are made in
accordance with the scheme and are expensed in the income statement as incurred.

In 2013, the Dutch Government imposed a crisis wage tax
payable by employers. The total charge in 2013, included in General and administrative costs, amounted to 417,000. In 2014 and 2015, this crisis wage tax was no longer applicable.

The Profit from sale of financial asset reflects the profit realized on the sale of the
Groups shares in iStreamPlanet Co.

In 2015, the Interest expense on Senior Secured Notes, bank and other loans
increased principally as result of the full year impact of the Additional Notes issued in 2014, and lower capitalized borrowing costs.

In
2014, the Interest expense on Senior Secured Notes, bank and other loans increased principally as result of the increased interest expenses related to the Additional Notes amounting to 150 million partly offset by higher
capitalized borrowing costs.

As a result of the refinancing completed on July 3, 2013, the Company incurred costs, presented in
Other financial expenses, of approximately 31 million of which 26.5 million in cash related to the tender and redemption premiums and consent fees for the 9.50% Senior Secured Notes due 2017 (the Senior Secured Notes
due 2017) and 4.5 million non-cash expenses from the deferred financing costs related to the former 60 million Revolving Facility Agreement and the unamortized costs of the Senior Secured Notes due 2017.

The Interest expense on provision for onerous lease contracts related to the unwinding of the discount rate used to calculate the
Provision for onerous lease contracts.

Senior Secured Notes due 2017

On June 3,
2013, the Company announced an offer to purchase for cash any and all of its outstanding euro-denominated 260 million Senior Secured Notes due 2017.

On June 28, 2013, holders of 256,962,000 aggregate principal amount of the 260 million Senior Secured Notes due 2017, representing
98.8% of the outstanding Notes, had validly tendered their Notes.

The total consideration for each 1,000 principal amount of the
260 million Senior Secured Notes due 2017 validly tendered prior to the consent deadline was 1,102 and after the consent deadline 1,092 plus the accrued and unpaid interest up to, but not including, the day of settlement.

On July 3, 2013, the tender was completed and the Company discharged its obligations with respect to the remaining 3,038,000 outstanding
260 million Senior Secured Notes due 2017 not purchased in the offer in accordance with the satisfaction and discharge provisions of the indenture governing the 260 million Senior Secured Notes due 2017. These Notes were redeemed on

2017, plus accrued and unpaid interest up to, but not including, the redemption date.

The total redemption fees amounted to approximately
26.5 million; in addition, the Company incurred approximately 4.5 million in non-cash expenses from the deferred financing costs relating to the former 60 million Revolving Facility Agreement and the unamortized costs of the Senior

due 2017, which were tendered in the offer for those notes and to redeem the 260 million Senior Secured Notes due 2017 which remained outstanding following the expiration and settlement of the tender offer and consent solicitation, to pay all
related fees, expenses and premiums and for other general corporate purposes.

to cancel its commitment under the revolving facility agreement as a result of that event, such lenders commitments will be immediately cancelled and its participation in all outstanding loans shall, together with the accrued and unpaid

Covenants

The Revolving Facility Agreement contains various covenants that restrict, among other things and subject to certain exceptions, the ability of
the Company and its subsidiaries to:



| |  |  | create certain liens;
| | - |  | ---------------------



| |  |  | incur debt and/or guarantees;
| | - |  | -----------------------------



| |  |  | enter into transactions other than on arms-length basis;
| | - |  | ---------------------------------------------------------



| |  |  | pay dividends or make certain distributions or payments;
| | - |  | --------------------------------------------------------



| |  |  | engage, in relation to the Company, in any business activity or own assets or incur liabilities not authorized by the Revolving Facility Agreement;
| | - |  | ---------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | sell certain kinds of assets;
| | - |  | -----------------------------



| |  |  | enter into any sale and leaseback transactions;
| | - |  | -----------------------------------------------



| |  |  | make certain investments or other types of restricted payments;
| | - |  | ---------------------------------------------------------------



| |  |  | substantially change the nature of the Company or the Groups business;
| | - |  | -----------------------------------------------------------------------



| |  |  | designate unrestricted subsidiaries; and
| | - |  | ----------------------------------------



| |  |  | effect mergers, consolidations or sale of assets.
| | - |  | -------------------------------------------------

The Revolving Facility also requires the
Company to maintain a specified financial ratio. The restrictive covenants are subject to customary exceptions including, in relation to the incurrence of additional debt, a consolidated fixed charge ratio (calculated as a ratio of adjusted EBITDA
to consolidated interest expense) to exceed 2.00 to 1.00 on a pro forma basis for the four full fiscal quarters (taken as one period) for which financial statements are available immediately preceding the incurrence of such debt and, if such debt is
senior debt, a consolidated senior leverage ratio (calculated as a ratio of outstanding senior debt net of cash and cash equivalents of the Company and its restricted subsidiaries (on a consolidated basis) to pro forma adjusted EBITDA) to be less
than 4.00 to 1.00 on a pro forma basis for the four full fiscal quarters (taken as one period) for which financial statements are available immediately preceding the incurrence of such debt.

The Revolving Facility Agreement also includes a leverage ratio financial covenant (tested on a quarterly basis) requiring total net debt
(calculated as a ratio to pro forma EBITDA) not to exceed a leverage ratio of 4.00 to 1.00. In addition, the Company must ensure, under the Revolving Facility Agreement, that the guarantors represent a certain percentage of adjusted EBITDA of the
Group as a whole and a certain percentage of the consolidated net assets of the Group as a whole. Our ability to meet these covenants may be affected by events beyond our control and, as a result, we cannot assure you that we will be able to meet
the covenants. In the event of a default under our Revolving Facility, the lenders could terminate their commitments and declare all amounts owed to them to be due and payable. Borrowings under other debt instruments that contain cross acceleration
or cross default provisions, including the Senior Secured Notes, may as a result also be accelerated and become due and payable.

leverage ratio could result in a default under the Revolving Facility Agreement. As of December 31, 2015, the Company was in compliance with all covenants in the Revolving Facility Agreement. In addition, the Company does not anticipate any
such breach or failure and believes that its ability to borrow funds under the Revolving Facility Agreement will not be adversely affected by the covenants in the next 12 months.

| |  |  | guarantees certain debt.
| | - |  | ------------------------

The Group seeks to minimize the risk related to cash and cash equivalents by holding cash as
widely as possible across multiple bank institutions. Term risk is limited to deposits of no more than two weeks. The Group monitors its cash position, including counterparty and term risk, daily.

The Group seeks to minimize the credit risk related to customers by analyzing new customers individually for creditworthiness before it begins
to trade. If customers are independently rated, these ratings are used. If, there is no independent rating, the credit quality of the customer is analyzed taking its financial position, past experience and other factors into account.

The Groups largest financial asset balance exposed to credit risk is with a financial institution, one of the Companys
relationships banks, which accounts for approximately 26% of the total balance exposed to credit risk as at December 31, 2015.

The mortgages on the PAR3 land, owned by Interxion Real Estate II Sarl, and the PAR5 land, owned by Interxion
Real Estate III Sarl have variable interest rates based on EURIBOR plus an individual margin ranging from 240 to 280 basis points. The interest rates have been fixed for 75% of the principal outstanding amount for a period of ten years, which has
been reflected in the table above.

Cash flow sensitivity analysis for fixed-rate instruments

The Group does not account for any fixed-rate financial assets and liabilities at fair value through profit and loss, and does not designate
derivatives (interest rate swaps) as hedging instruments under a fair value hedge accounting model. Therefore a change in interest rates at the end of the reporting period would not affect profit or loss.

Cash flow sensitivity analysis for variable rate instruments

A change of 100 basis points in interest rates payable at the reporting date would have increased (decreased) equity and profit or loss by the
amounts shown below. This analysis assumes that all other variables, in particular foreign currency rates, remained constant.

Fair values and hierarchy

Fair values versus carrying amounts

As of
December 31, 2015, the market price of the 6.00% Senior Secured Notes due 2020 was 105.780 (2014: 105.005 and 2013: 106.51). Using this market price, the fair value of the Senior Secured Notes due 2020 would have been approximately 502
million, compared with its nominal value of 475 million. In 2014 the value of the notes was 499 million compared with a nominal value of 475 million.

Until 2014, the Group had a financial asset carried at fair value, its investment in iStreamPlanet Inc. This investment was sold during 2015.
Furthermore the Group had a cash flow hedge carried at a negative fair value, to hedge the interest rate risk of part of two mortgages.

As of December 31, 2015, the fair value of all mortgages would have been equal to their carrying amount of 44.1 million. As of 31
December 2015, the fair value of the financial lease liabilities would have been 41.0 million compared with its carrying amount of 34.6 million.

Fair value hierarchy

The Company
regularly reviews significant unobservable inputs and valuation adjustments. If third party information, such as broker quotes or pricing services, is used to measure fair values, then the Company assesses the evidence obtained from the third
parties to support the conclusion that such valuations meet the requirements of IFRS, including the level in the fair value hierarchy in which such valuations should be classified. Significant valuation issues are reported to the Companys
Audit Committee.

When measuring the fair value of an asset or a liability, the Company uses observable market data as far as possible.
Fair values are categorized into different levels in a fair value hierarchy based on the inputs used in the valuation techniques as follows:



|         |  |  |  |                                                                                                                                                                                  
|-------- |  |  |  | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
|Level 1: |  |  |  | quoted prices (unadjusted) in active markets for identical assets or liabilities                                                                                                 
|         |  | 
|Level 2: |  |  |  | inputs other than quoted prices included within Level 1 that are observable for the asset or liability, either directly (i.e. as prices) or indirectly (i.e. derived from prices)
|         |  | 
|Level 3: |  |  |  | inputs for the asset or liability that are not based on observable market data (unobservable inputs).                                                                            

If the inputs used to measure the fair value of an asset or a liability fall into different levels of the fair
value hierarchy, then the fair value measurement is categorized in its entirety in the same level of the fair value hierarchy as the lowest level input that is significant to the entire measurement. The Company recognizes transfers between levels of
the fair value hierarchy at the end of the reporting period during which the change has occurred.

No changes in levels of hierarchy, or transfers between levels, occurred in the reporting period. Fair values
were obtained from quoted market prices in active markets or, where no active market exists, by using valuation techniques. Valuation techniques include discounted cash flow models using inputs as market interest rates and cash flows.

The financial asset which was in Level 3 until 2014, has been sold during the year. The profit realized on this divestment is disclosed in
note 9.

Capital management

The
Boards policy is to maintain a strong capital base so as to maintain investor, creditor and market confidence and to sustain future development of the business. The Board of Directors monitors the return on capital.

For his contribution to the Company in 2013, the Executive Director, based on the
Companys performance and his individual performance, earned an initial allocation of 71,979 performance shares. This number was calculated on the basis of the predetermined conditionally awarded on target equity value for 2013, the
Companys average share value during the month of January 2013, as well as the actual Company and individual performance from January 1, 2013 to December 31, 2013. On June 30, 2014, the General Meeting of Shareholders approved to grant 17,995
performance shares, which represented 25% of the initial allocation, to the Executive Director pursuant to the Companys 2013 Amended International Equity Based Incentive Plan. This first installment, 25% (17,995 performance shares) of the
initial allocation, vested immediately following the approval by the General Meeting of Shareholders of the award. To cover taxes due, the Executive Director sold 4,995 shares. The remainder of the vested shares were locked up until December 31,
2014 and were transferred in March 2015. The remaining 75% of the initial allocation (53,984 performance shares) was subject to the Companys relative share performance over the 24 month period from January 1, 2013 to December 31, 2014. Since
at December 31, 2014, the relative share performance criteria were not met, the 53,984 performance shares were forfeited and returned to the pool available for grant.

Employee expenses

In 2015, the Company recorded employee expenses of 7,161,000 related to share-based payments (2014: 6,576,000 and 2013:
4,149,000). The 2015 share-based payments related expenses include an amount of  643,000 related to taxes and social security charges (2014:  92,000 and 2013: 559,000).

The weighted average fair value at grant date of options granted during the period was determined using the Black-Scholes valuation model. The
following inputs were used:



|                                                          |  |      |             |  |      |  |             |      |  |  |             |

The significant inputs into the model were:



| |  |  | expected volatility is based on a combination of the performance of the Company and, given the relatively short period that the shares of the Company are traded publicly, other companies that are considered to be
comparable to the Group;
| | - |  | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | the risk-free interest rate based on the yield on zero coupon bonds issued by the European Central Bank for European Union government debt rates with a maturity similar to the expected life of the options;
| | - |  | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | dividend yield is considered to be nil;
| | - |  | ---------------------------------------



| |  |  | expected life is considered to be equal to the average of the share option exercize and vesting periods.
| | - |  | --------------------------------------------------------------------------------------------------------

The weighted average fair value at grant date of the performance shares granted during the period was determined using the Monte Carlo
valuation model. In addition to the above mentioned inputs a one year holding discount of 5.5% was used as input for the performance shares.

Change of control clauses

Some awards to key management contain change of control clauses. If after a change of control of the Company (including any of its successors),
the employment agreement is terminated or if the participant is offered a function which is a material demotion to his current position, all options, restricted and performance shares will vest and become exercisable immediately. Should
the employment agreement, other than as the result of a change of control, be terminated prior to the date that all options have vested and should the participant and the Company not have agreed that he will be providing support or services to the
Company in another capacity, the non-vested options will expire with immediate effect.

There are no material transactions with related parties,
other than disclosed below, and all transactions are conducted at arms length.

Share distribution by Baker Capital

On June 2, 2015, Lamont Finance N.V. and Baker Communications Fund II, L.P. requested that Interxion instruct its Transfer Agent, American
Stock Transfer & Trust Company, to remove the restrictive legend on all of the 18,657,592 Interxion shares held by Lamont Finance N.V. and Baker Communications Fund II, L.P.

Baker Capital (Baker) made a pro rata distribution-in-kind of these shares immediately to the partners of Baker Communications
Fund II (Cayman) L.P. and Baker Communications Fund II L.P., which funds had made their initial acquisition of Interxion shares in 2000. Under the terms of the undertaking executed by Baker in support of the proposed transaction between Interxion
and TelecityGroup plc, it was contemplated that Baker would make a full distribution of its shares to its partners upon the closing of the transaction. The distribution was made following the termination of the proposed transaction with
TelecityGroup plc and the related undertaking executed by Baker. Following the distribution, Baker owns shares constituting less than 1% of the outstanding ordinary shares of Interxion.

This distribution did not have any effect upon the total number of shares outstanding.

As a result of the 18.6 million share distribution by funds affiliated with Baker, Mr. John Baker (on June 5) and Mr. Rob Manning (on June 7),
as representatives of Baker on the Board of Directors (the Board), tendered their resignations as members of the Board, effective immediately. Mr. Jean F.H.P. Mandeville was appointed as the new Chairman of the Board replacing Mr. Baker,
effective June 8, 2015. Pursuant to our Articles of Association, the Board is comprised of at least one Executive Director and three Non-executive Directors. At most the Board shall be comprised of seven Directors, a majority of which shall be
Non-executive Directors. Consequently the current composition of the Board is compliant with the Companys Articles. The Company may decide to increase the number of Directors in accordance with its Articles.

On June 8, 2015, the Board of Directors of the Company adopted amendments to the Companys Bylaws to eliminate references to the
Shareholders Agreement and related provisions.

developing a panel of services, such as public peering (allowing a network to connect to many other networks) and private peering (connecting one network to another network) and by bringing together French and foreign ISPs and Internet services and
content providers. In 2011, Interxion France incurred costs which were recharged to France-IX association, receipt of which has been formalized in a loan agreement which was fully repaid in 2015 (outstanding balance per December 31, 2014:
