Business Wire

DALLAS -- August 7, 2013

Global data center service provider CyrusOne Inc, (NASDAQ: CONE), which
specializes in providing highly reliable enterprise-class, carrier-neutral
data center properties to the Fortune 1000, announced second quarter 2013
earnings today.

Second Quarter Highlights

  *Leased 37,000 colocation square feet, a 19% sequential quarterly increase
    and almost doubling last year's results, before including a lease signed
    in July for approximately 19,500 colocation square feet that sells out the
    San Antonio facility
  *Revenue of $63.6 million - an increase of 18% over the second quarter of
    2012
  *Added three of the Fortune 1000 as new customers, bringing total Fortune
    1000 customers to 122
  *Successfully launched the CyrusOne National Internet Exchange (IX), as 68%
    of new leases in the quarter included incremental IX services which
    increased monthly rent on those leases by 23%
  *Commissioned a new facility in Houston and closed on the acquisitions of
    three previously leased data centers increasing Net Operating Income from
    owned facilities to 70%
  *Acquired 22 acres of land for $6.6 million in San Antonio in August for
    future data center expansion

"CyrusOne's second quarter reflects a continuation of the strong operating and
financial performance that we delivered in the first quarter of the year. We
leased 37,000 square feet of space, or about 19% more than we did last quarter
and almost 100% higher than last year, which contributed to the 18% year over
year increase in organic revenue growth. This is our strongest leasing ever in
the first half of a year," said Gary Wojtaszek, president and chief executive
officer of CyrusOne. “We are also excited about the launch of our CyrusOne
National IX in April, which represents a real paradigm shift in how companies
access, manipulate and share their data. The CyrusOne National IX was greatly
received by existing and new customers with several customer wins in the
quarter solely driven by this new product offering."

Financial Results

Revenue was $63.6 million for the second quarter, compared to $54.0 million
for the same period in 2012, or an increase of 18% as organic revenue
increased from existing and newer facilities. Leasing activity continues to be
robust as enterprise companies increasingly realize the need to outsource
their data centers. Operating income improved $10.4 million from the second
quarter of 2012 as increased revenue of $9.6 million and an asset impairment
charge recorded in 2012 for $13.3 million was partially offset by higher
property operating expenses of $6.5 million and higher depreciation and
amortization of $5.2 million. Net loss was $6.8 million for the second
quarter, compared to a net loss of $9.9 million for the same period in 2012,
principally from a $10.4 million increase in operating income partially offset
by higher interest expense of $1.1 million, a loss on extinguishment of debt
associated with the acquisition of our Austin facility of $1.3 million, and an
income tax benefit of $4.6 million from the loss recorded in 2012 when
CyrusOne was a C-corporation.

Net operating income (NOI)^1 was $39.0 million for the second quarter,
compared to $35.9 million in the same period in 2012, an increase of 9%. NOI
increased on revenue growth of $9.6 million offset by higher property
operating expenses from new facilities and higher expenses at existing
facilities associated with power and maintenance costs as well as expenses
associated with launching the new interconnection platform.

Adjusted EBITDA^2 was $30.8 million for the second quarter, compared to $28.5
million in the same period in 2012, an increase of 8%. This rate of increase
was slower than growth in revenue and NOI as CyrusOne made additional
investments in sales and marketing to drive sales growth and increased general
and administrative expenses to support public company functions, as well as to
support the launch of the new interconnection platform. This resulted in an
Adjusted EBITDA margin of 48.4% in the second quarter as compared to 52.8% in
the same period in 2012.

Normalized Funds From Operations (Normalized FFO)^3 was $16.0 million for the
second quarter, compared to $20.5 million in the same period in 2012, a
decrease of 22%. The company has revised the definition of Normalized FFO to
exclude gains or losses on extinguishment of debt as these are non-recurring
charges that are not representative of the ongoing operations and performance
of the business. The decrease in Normalized FFO was primarily due to a $4.6
million income tax benefit recorded in the second quarter of 2012 when
CyrusOne was a C-corporation. Normalized FFO per diluted common share or
common share equivalent^4 was $0.25 in the second quarter of 2013. Excluding
the tax benefit, Normalized FFO would be consistent with prior year.

Adjusted Funds From Operations (AFFO)^5 was $14.8 million for the second
quarter, compared to $14.4 million in the same period in 2012, an increase of
3%.

Leasing Activity

CyrusOne leased approximately 37,000 colocation square feet (CSF) or 3.8 MW of
power in the second quarter, compared to 19,000 CSF in the same period in
2012. The company added three new Fortune 1000^6 customers in the period,
bringing the total to 122 customers in the Fortune 1000 and 573 customers in
total as of June 30, 2013. The weighted average lease term of the new leases
based on square footage was 65 months, and approximately 65% of the CSF was
leased to metered customers with the remainder leased on a full service basis.
Recurring rent churn^7 for the second quarter of 2013 was 1.2%, compared to
1.8% for the second quarter of 2012. The CyrusOne National IX, launched at the
beginning of the second quarter of 2013, is attracting both new customers and
increasing monthly rents as approximately 68% of the new leases this quarter
included IX services and increased their monthly average rent by 23%. During
the first week of July, the company executed a lease for approximately 19,500
CSF with one customer for the San Antonio facility, which is now fully leased
including the second data hall which will be completed in the third quarter.
In August, the company acquired 22 acres of land in San Antonio for $6.6
million as it plans for the next facility.

Portfolio Utilization and Development

CSF available as of June 30, 2013 were approximately 970,000 across 25
facilities, an increase of approximately 169,000, or 21%, from a year ago. In
the second quarter of 2013, the company added 49,000 CSF, including 42,000 CSF
commissioned in its new Houston West Facility. CSF were also added in
Cincinnati and Dallas. CSF utilization^8 for the second quarter was 81%,
compared to 85% in the same period in 2012 and consistent with the first
quarter of 2013.

In the second quarter, the company completed the purchase of the Industrial
Road (Florence), Springer Street (Lombard) and Metropolis Drive (Austin 2)
facilities for $28.2 million. These facilities were previously leased with a
combined annualized rent^9 of $20.5 million for June. As of the end of the
second quarter 2013, the company-owned facilities accounted for 70% of the NOI
and 77% of CSF respectively. Of the $28.2 million paid for the acquisition of
the properties, $8.4 million is presented as capital expenditures in the GAAP
cash flow statement with $19.8 million presented as repayment of debt. In
addition, the company recorded a loss on extinguishment of debt of $1.3
million on the purchase of the Austin 2 facility.

Balance Sheet and Liquidity

As of June 30, 2013, the company had $525.0 million of long term debt, cash of
$267.1 million, and an undrawn $225.0 million senior secured revolving credit
facility. With the acquisition of three of the leased facilities in the
quarter and regularly scheduled lease payments, the company's capital lease
liability decreased by $11.2 million and other financing arrangements
decreased by $8.9 million in the period. Net debt^10 was $277.7 million as of
June 30, 2013, or approximately 17% of the company's total enterprise value or
2.3x Adjusted EBITDA annualized. Available liquidity^11 was $492.1 million as
of June 30, 2013.

Dividend

On June 4, 2013, the company declared a dividend of $0.16 per share of common
stock and common stock equivalents for the second quarter of 2013. The
dividend was paid on July 15, 2013 to shareholders of record on June 28, 2013.

Use of Non-GAAP Financial Measures

This press release contains certain non-GAAP financial measures that
management believes are helpful in understanding the company's business, as
further discussed within this press release. These financial measures, which
include Funds From Operations, Normalized Funds From Operations, Adjusted
EBITDA, Net Operating Income and Net debt should not be construed as being
more important than comparable GAAP measures. Detailed reconciliations of
these non-GAAP financial measures to comparable GAAP financial measures have
been included in the tables distributed with this release and are available in
the Investor Relations section of www.cyrusone.com.

^1Net Operating Income (NOI) is defined as revenue less property operating
expenses. Amortization of deferred leasing costs is presented in depreciation
and amortization, which is excluded from NOI. CyrusOne has not historically
incurred any tenant improvement costs. Our sales and marketing costs consist
of salaries and benefits for our internal sales staff, travel and
entertainment, office supplies, marketing and advertising costs. General and
administrative costs include salaries and benefits of our senior management
and support functions, legal and consulting costs, and other administrative
costs. Marketing and advertising costs are not property specific, rather these
costs support our entire portfolio. As a result, we have excluded these
marketing and advertising costs from our NOI calculation, consistent with the
treatment of general and administrative costs, which also support our entire
portfolio.

^2Adjusted EBITDA is defined as net (loss) income as defined by U.S. GAAP
before noncontrolling interests plus interest expense, income tax (benefit)
expense, depreciation and amortization, non-cash compensation, transaction
costs and transaction-related compensation, including acquisition pursuit
costs, loss on sale of receivables to affiliate, restructuring costs, loss on
extinguishment of debt, asset impairments and excluding (gain) loss on sale of
real estate improvements. Other companies may not calculate Adjusted EBITDA in
the same manner. Accordingly, the company's Adjusted EBITDA as presented may
not be comparable to others.

^3Normalized Funds From Operations (Normalized FFO) is defined as Funds From
Operations (FFO) plus transaction costs, including acquisition pursuit costs,
transaction-related compensation, and (gain) loss on extinguishment of debt.
FFO represents net (loss) income computed in accordance with U.S. GAAP before
noncontrolling interests, (gain) loss from sales of real estate improvements,
real estate-related depreciation and amortization, amortization of customer
relationship intangibles, and real estate and customer relationship intangible
impairments. Because the value of the customer relationship intangibles is
inextricably connected to the real estate acquired, CyrusOne believes the
amortization and impairments of such intangibles is analogous to real estate
depreciation and impairments; therefore, the company adds the customer
relationship intangible amortization and impairments back for similar
treatment with real estate depreciation and impairments. CyrusOne's customer
relationship intangibles are primarily associated with the acquisition of
Cyrus Networks in 2010 and, at the time of acquisition, represented 22% of the
value of the assets acquired. The company believes its Normalized FFO
calculation provides a comparable measure to others in the industry.

^4Normalized FFO per diluted common share or common share equivalent is
defined as Normalized FFO divided by the average diluted common shares and
common share equivalents outstanding for the quarter, which were approximately
64.7 million for the second quarter of 2013.

^5Adjusted Funds From Operations (AFFO) is defined as Normalized FFO plus
amortization of deferred financing costs, non-cash compensation, and non-real
estate depreciation and amortization, less deferred revenue and straight line
rent adjustments, leasing commissions, recurring capital expenditures, and
non-cash corporate income tax benefit and expense.

Management uses FFO, Normalized FFO, Adjusted EBITDA, NOI and AFFO as
supplemental performance measures because they provide performance measures
that, when compared year over year, capture trends in occupancy rates, rental
rates and operating costs. The company also believes that, as widely
recognized measures of the performance of real estate investment trusts
(REITs) and other companies, these measures will be used by investors as a
basis to compare its operating performance with that of other companies. Other
companies may not calculate these measures in the same manner, and, as
presented, they may not be comparable to others. Therefore, FFO, Normalized
FFO, NOI, AFFO and Adjusted EBITDA should be considered only as supplements to
net income as measures of our performance. FFO, Normalized FFO, NOI, AFFO and
Adjusted EBITDA should not be used as measures of liquidity nor as indicative
of funds available to fund the company's cash needs, including the ability to
make distributions. These measures also should not be used as supplements to
or substitutes for cash flow from operating activities computed in accordance
with U.S. GAAP.

^6Fortune 1000 customers include subsidiaries whose ultimate parent is a
Fortune 1000 company or a foreign or private company of equivalent size.

^7Recurring rent churn is calculated as any reduction in recurring rent due to
customer terminations, service reductions or net pricing decreases as a
percentage of annualized rent at the beginning of the period, excluding any
impact from metered power reimbursements or other usage-based billing.

^8Utilization is calculated by dividing CSF under signed leases for available
space (whether or not the contract has commenced billing) by total CSF.
Utilization rate differs from percent leased presented in the Data Center
Portfolio table because utilization rate excludes office space and supporting
infrastructure net rentable square footage and includes CSF for signed leases
that have not commenced billing. Management uses utilization rate as a measure
of CSF leased.

^9Annualized rent represents monthly contractual rent (defined as cash rent
including customer reimbursements for metered power) under existing customer
leases as of June 30, 2013, multiplied by 12. For the month of June 2013,
annualized rent was approximately $236.4 million and customer reimbursements
were $22.2 million annualized, consisting of reimbursements by customers
across all facilities with separately metered power.

^10Net debt provides a useful measure of liquidity and financial health. The
company defines net debt as long-term debt and capital lease obligations,
offset by cash, cash equivalents, and temporary cash investments.

^11Liquidity is calculated as cash, cash equivalents, and temporary cash
investments on hand plus the undrawn capacity on CyrusOne's corporate
revolving credit facility.

*** The information provided for the West Seventh Street (7th St.) property
includes data for two facilities, one of which we lease and one of which we
own.

(a) Represents the total square feet of a building under lease or available
for lease based on engineers’ drawings and estimates but does not include
space held for development or space used by CyrusOne.

(b) Represents monthly contractual rent (defined as cash rent including
customer reimbursements for metered power) under existing customer leases as
of June 30, 2013, multiplied by 12. For the month of June 2013, customer
reimbursements were $22.2 million annualized and consisted of reimbursements
by customers across all facilities with separately metered power. Customer
reimbursements under leases with separately metered power vary from
month-to-month based on factors such as our customers’ utilization of power
and the suppliers’ pricing of power. From July1, 2011 through June 30, 2013,
customer reimbursements under leases with separately metered power constituted
between 7.2% and 9.7% of annualized rent. After giving effect to abatements,
free rent and other straight-line adjustments, our annualized effective rent
as of June30, 2013 was $252,020,125. Our annualized effective rent was
greater than our annualized rent as of June 30, 2013 because our positive
straight-line and other adjustments and amortization of deferred revenue
exceeded our negative straight-line adjustments due to factors such as the
timing of contractual rent escalations and customer prepayments for services.

(c) CSF represents the NRSF at an operating facility that is currently leased
or readily available for lease as colocation space, where customers locate
their servers and other IT equipment.

(d) Represents the NRSF at an operating facility that is currently leased or
readily available for lease as space other than CSF, which is typically office
and other space.

(e) Represents infrastructure support space, including mechanical,
telecommunications and utility rooms, as well as building common areas.

(f) Represents the NRSF at an operating facility that is currently leased or
readily available for lease. This excludes existing vacant space held for
development.

(g) Percent leased is determined based on NRSF being billed to customers under
signed leases as of June30, 2013 divided by total NRSF. Leases signed but not
commenced as of June30, 2013 are not included. Supporting infrastructure has
been allocated to leased NRSF on a proportionate basis for purposes of this
calculation.

(h) Represents space that is under roof that could be developed in the future
for operating NRSF, rounded to the nearest 1,000.

(i) Represents installed power capacity that can be delivered to the facility
by the local utility provider. May not sum to total due to rounding.

(a) Includes affiliates.

(b) Represents monthly contractual rent (defined as cash rent including
customer reimbursements for metered power) under existing customer leases as
of June30, 2013, multiplied by 12. For the month of June 2013, our total
portfolio annualized rent was $236.4 million, and customer reimbursements were
$22.2 million annualized, consisting of reimbursements by customers across all
facilities with separately metered power. Customer reimbursements under leases
with separately metered power vary from month-to-month based on factors such

our annualized rent as of June30, 2013 because our positive straight-line and
other adjustments and amortization of deferred revenue exceeded our negative
straight-line adjustments due to factors such as the timing of contractual
rent escalations and customer prepayments for services.

(c) Represents the customer’s total annualized rent divided by the total
annualized rent in the portfolio as of June30, 2013, which was approximately
$236.4 million.

(d) Weighted average based on customer’s percentage of total annualized rent
expiring and is as of June30, 2013, assuming that customers exercise no
renewal options and exercise all early termination rights that require payment
of less than 50% of the remaining rents. Early termination rights that require
payment of 50% or more of the remaining lease payments are not assumed to be
exercised because such payments approximate the profitability margin of
leasing that space to the customer, such that we do not consider early
termination to be economically detrimental to us.

(e) Includes information for both Cincinnati Bell Technology Solutions (CBTS)
and Cincinnati Bell Telephone and two customers that have contracts with CBTS.
We expect the contracts for these two customers to be assigned to us, but the
consents for such assignments have not yet been obtained. Excluding these
customers, Cincinnati Bell Inc. and subsidiaries represented 3.0% of our
annualized rent as of June30, 2013.

(a) Leases that were auto-renewed prior to June30, 2013 are shown in the
calendar year in which their current auto-renewed term expires. Unless
otherwise stated in the footnotes, the information set forth in the table
assumes that customers exercise no renewal options and exercise all early
termination rights that require payment of less than 50% of the remaining
rents. Early termination rights that require payment of 50% or more of the
remaining lease payments are not assumed to be exercised because such payments
approximate the profitability margin of leasing that space to the customer,
such that we do not consider early termination to be economically detrimental
to us.

(b) Number of leases represents each agreement with a customer. A lease
agreement could include multiple spaces and a customer could have multiple
leases.

(c) Represents monthly contractual rent (defined as cash rent including
customer reimbursements for metered power) under existing customer leases as
of June30, 2013, multiplied by 12. For the month of June 2013, customer
reimbursements were $22.2 million annualized and consisted of reimbursements
by customers across all facilities with separately metered power. Customer
reimbursements under leases with separately metered power vary from
month-to-month based on factors such as our customers’ utilization of power
and the suppliers’ pricing of power. From July 1, 2011 through June30, 2013,
customer reimbursements under leases with separately metered power constituted
between 7.2% and 9.7% of annualized rent. After giving effect to abatements,
free rent and other straight-line adjustments, our annualized effective rent
as of June30, 2013 was $252,020,125. Our annualized effective rent was
greater than our annualized rent as of June30, 2013 because our positive
straight-line and other adjustments and amortization of deferred revenue
exceeded our negative straight-line adjustments due to factors such as the
timing of contractual rent escalations and customer prepayments for services.

(d) Represents the final monthly contractual rent under existing customer
leases that had commenced as of June30, 2013, multiplied by 12.
