CyrusOne Reports First Quarter 2013 Earnings

Revenue and Normalized FFO growth of 15% for first quarter

DALLAS (May 8, 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 first quarter 2013 earnings today.

First Quarter Highlights

• Leased 31,000 square feet of colocation space, up 100% over first quarter of 2012, adding four of the Fortune 1000, bringing total Fortune 1000 customers to 119

• Revenue growth of 15% and Adjusted EBITDA increase of 11% compared to the first quarter of 2012

• Normalized FFO increased 15% while AFFO increased 45% from first quarter of 2012

• Acquired two previously leased data centers in May 2013

• Purchased an additional 33 acres of land adjacent to the Houston West data center

• Launched the CyrusOne Texas Internet Exchange (IX)

“We are very pleased with our inaugural first quarter results which reflect the broad secular trends that are driving our industry, the continued demand by Fortune 1000 customers for CyrusOne’s products and services and the financial strength of our differentiated platform,” said Gary Wojtaszek, President and Chief Executive Officer.

Financial Results

CyrusOne closed on its initial public offering (IPO) on January 24, 2013. Prior to its IPO, CyrusOne was a wholly owned subsidiary of Cincinnati Bell Inc. (NYSE:CBB). The discussion below combines the results of operations for the period January 1, 2013 through January 23, 2013 and the period from January 24, 2013 through March 31, 2013 to provide a meaningful comparison to the results of operations for the quarter ended March 31, 2012.

Revenue for the first quarter of 2013 was $60.1 million, up from $52.1 million in the first quarter of 2012, an increase of 15%. Recurring rent churn¹ was 0.4% for the first quarter of 2013, or 1.6% annualized, compared to 0.5% for the first quarter of 2012 and 4.6% annual recurring rent churn for the full year 2012.

CyrusOne’s net loss for the first quarter of 2013 was $23.0 million compared to a net loss of $0.7 million for the first quarter of 2012. The higher loss was due primarily to transaction-related compensation expense of $20.0 million recorded in the first quarter of 2013 related to employee incentive plans put into place by Cincinnati Bell related to the CyrusOne IPO. This was a non-cash expense to CyrusOne as the payments were reimbursed by Cincinnati Bell. Higher depreciation and amortization in the first quarter of 2013 was mostly offset by increased net operating income (NOI)². NOI for the quarter was $40.0 million, an increase of 15% from the first quarter of 2012, resulting from organic growth at existing and newly constructed facilities. CyrusOne’s owned facilities accounted for 62% of the first quarter 2013 NOI and 64% of colocation square feet (CSF).

Adjusted EBITDA³ increased to $31.5 million for the first quarter of 2013, from $28.3 million for the first quarter of 2012, an increase of 11%. The increase in Adjusted EBITDA from the growth in NOI was partially offset by increases in sales and marketing and general and administrative expenses as CyrusOne made investments to support public company functions and invest in future growth during 2012 and the first quarter of 2013. Adjusted EBITDA margins improved to 52% in the first quarter of 2013 as compared to 49% in the fourth quarter of 2012 due to seasonally lower sales and marketing expenses and lower utility costs, partially offset by increased general and administrative expenses.

Normalized Funds From Operations (Normalized FFO)⁴, which excludes transaction costs and transaction-related compensation, was $17.2 million, an increase of 15% from the first quarter of 2012. The increase is from higher Adjusted EBITDA and certain nonrecurring charges in the first quarter of 2012. Normalized FFO per diluted common share or common share equivalent⁵ was $0.27 in the first quarter of 2013, assuming the diluted common shares and common share equivalents were outstanding for the entire first quarter of 2013. Adjusted Funds From Operations (AFFO) ⁶ increased to $17.5 million in the first quarter of 2013, up 45% from the prior year.

Leasing Activity

During the quarter, CyrusOne signed new leases for approximately 31,000 CSF, or 3.1MW of power, compared to 15,000 CSF in the first quarter of 2012. CyrusOne added four new Fortune 1000⁷ customers, bringing the total to 119 customers in the Fortune 1000. The weighted average lease term based on square footage was 71 months, and approximately 72% of the square footage was leased to metered power customers with the remainder leased on a full service basis.

Portfolio Utilization and Development

CSF available was approximately 921,000 across 24 facilities as of March 31, 2013, up 113,000 CSF or 14% from March 31, 2012. Total CSF available declined from December 31, 2012 by 11,000 CSF as 16,000 CSF at the West Seventh Street facility in Cincinnati was decommissioned. In the fourth quarter of 2012, a customer renewed their contract of legacy low power CSF, reducing their footprint by 16,000 CSF. The rate on the renewed lease, however, increased over 4 times yielding a net increase in revenue despite leasing less space. This low power CSF was decommissioned and is expected to be developed into data center space that will generate higher amounts of revenue than the prior lease. CyrusOne also added 5,000 CSF in its Kestral Way (London) facility in the first quarter of 2013.

CSF utilization⁸ as of March 31, 2013 was 81%, compared to 85% at March 31, 2012. Excluding space that was decommissioned at the West Seventh Street facility, total capacity expanded 21% while utilized square footage increased 16%. In the quarter, we leased approximately 31,000 CSF across our portfolio, including 13,000 at our South Ellis Street (Phoenix) facility, which opened in late December 2012.

The new building expansion at Westway Park Blvd (Houston West) facility was completed in April 2013, and CyrusOne commissioned approximately 42,000 CSF in the first data hall. In March, CyrusOne acquired 33 acres in Houston, adjacent to its Westway Park Blvd (Houston West) facility, for $18.2 million, expanding the campus to over 45 acres, creating the largest digital energy campus in Houston. In May 2013, CyrusOne purchased its Industrial Road (Florence) and Springer Street (Lombard) facilities for $16 million, and CyrusOne is currently under contract to acquire its Metropolis Drive (Austin 2) facility in the second quarter of 2013. These facilities were previously leased with a combined annualized rent⁹ of $18.7 million for March 2013, and pro forma for these purchases, CyrusOne’s owned facilities accounted for 70% of the first quarter 2013 NOI and 76% of CSF as of March 31, 2013.

Interconnection Initiative

Last month CyrusOne deployed its Texas IX, which is a unique platform that creates a true paradigm shift in the way CyrusOne has solved big data challenges faced by its enterprise customers. CyrusOne architected a solution that can solve both data center and connectivity needs, providing tremendous scalability by combining CyrusOne’s Massively Modular facility architecture with its robust connectivity platform in the state of Texas. The on-net platform is deployed across CyrusOne facilities in Austin, Dallas, Houston and San Antonio and enables customers to connect to their own enterprise-owned facilities and to third-party facilities to seamlessly engage the full ecosystem of business partners, content providers, networks, carriers, Internet service providers, and Ethernet buyers and sellers. The platform provides customers freedom of choice about how to build out capacity when transporting large amounts of data—by choosing CyrusOne’s bandwidth marketplace, its Internet Exchange platform, or a cross-connect to cloud services.

The platform enables customers to establish robust, low-latency, multi-point connections between a broad range of facilities or centers. It is also the easiest and fastest way for customers to gain all the benefits associated with lower wholesale transit purchase costs and peering. The CyrusOne Texas IX offers reduced service costs, with free Internet Exchange ports at all on-net CyrusOne facilities and third-party carrier hotels.

Balance Sheet and Liquidity

As of March 31, 2013, CyrusOne had $556.0 million of long term debt, cash of $328.6 million, and an undrawn $225.0 million senior secured revolving credit facility. Net debt¹⁰ was $227.4 million, or approximately 13% of our total enterprise value or 1.8x our Adjusted EBITDA annualized. Available liquidity¹¹ as of March 31, 2013 was $553.6 million.

Dividend

On March 20, 2013, CyrusOne declared a dividend of $0.16 per share of common stock and common stock equivalents for the first quarter of 2013. The dividend was paid on April 15, 2013 to shareholders of record on March 29, 2013.

These statements are based on current expectations, estimates, forecasts, and projections about the industries in which we operate and the beliefs and assumptions of our management. Words such as “expects,” “anticipates,” “predicts,” “projects,” “intends,” “plans,” “believes,” “seeks,” “estimates,” “continues,” “endeavors,” “strives,” “may,” variations of such words and similar expressions are intended to identify such forward-looking statements.

Factors that could cause or contribute to such differences include, but are not limited to, those discussed in this release and those discussed in other documents we file with the Securities and Exchange Commission (SEC).

Actual results may differ materially and adversely from those expressed in any forward-looking statements. We undertake no obligation to revise or update any forward-looking statements for any reason.

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 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.

¹Recurring 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.

²Net Operating Income (NOI) is calculated 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,

5

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.

³Adjusted EBITDA is calculated 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.

⁴Normalized Funds From Operations (Normalized FFO) is calculated as Funds From Operations (FFO) plus transaction costs and transaction-related compensation, including acquisition pursuit costs. 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.

⁵Normalized FFO per diluted common share or common share equivalent is calculated as Normalized FFO divided by all diluted common shares and common share equivalents as if they were converted to common shares and were outstanding as of January 1, 2013.

⁶Adjusted Funds From Operations (AFFO) is calculated 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

6

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, AFFO, NOI and Adjusted EBITDA should be considered only as supplements to net income as measures of our performance. FFO, Normalized FFO, AFFO, NOI 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.

⁷Fortune 1000 customers include subsidiaries whose ultimate parent is a Fortune 1000 company or a foreign or private company of equivalent size.

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.

⁹ Annualized rent represents monthly contractual rent (defined as cash rent including customer reimbursements for metered power) under existing customer leases as of March 31, 2013, multiplied by 12. For the month of March 2013, annualized rent was approximately $225.7 million and customer reimbursements were $20.3 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.

* Indicates properties in which we hold a leasehold interest in the building shell and land. All data center infrastructure has been constructed by us and owned by us.

** Indicates properties in which we hold a leasehold interest in the building shell, land, and all data center infrastructure.

*** 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 March 31, 2013, multiplied by 12. For the month of March 2013, customer reimbursements were $20.3 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 April 1, 2011 through March 31, 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 March 31, 2013 was $236,267,428. Our annualized effective rent was greater than our annualized rent as of March 31, 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 March 31, 2013 divided by total NRSF. Leases signed but not commenced as of March 31, 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. Does 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 March 31, 2013, multiplied by 12. For the month of March 2013, customer reimbursements were $20.3 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 April 1, 2011 through March 31, 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 March 31, 2013 was $236,267,428. Our annualized effective rent was greater than our annualized rent as of March 31, 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 March 31, 2013, which was approximately $225.7 million.

(d) Weighted average based on customer’s percentage of total annualized rent expiring and is as of March 31, 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 2.8% of our annualized rent as of March 31, 2013.

(a) Leases that were auto-renewed prior to March 31, 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 March 31, 2013, multiplied by 12. For the month of March 2013, customer reimbursements were $20.3 million annualized and consisted of reimbursements by customers across all facilities with separately metered power.

After giving effect to abatements, free rent and other straight-line adjustments, our annualized effective rent as of March 31, 2013 was $236,267,428. Our annualized effective rent was greater than our annualized rent as of March 31, 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 March 31, 2013, multiplied by 12.
