“We had one of the highest quarterly leasing totals in the Company’s history and continued strong financial performance, with Revenue and Adjusted EBITDA each growing over 30%” said Gary Wojtaszek, president and chief executive officer of CyrusOne. “We are excited to begin our global expansion by establishing a presence in the two largest markets in Europe, London and Frankfurt, at a time when demand across the continent has accelerated and our customers are increasingly asking us to support their international growth objectives.”

First Quarter 2018 Financial Results

Revenue was $196.6 million for the first quarter, compared to $149.3 million for the same period in 2017, an increase of 32%. The increase in revenue was driven primarily by a 29% increase in occupied CSF, lease termination fees totaling $5.0 million, and additional interconnection services. The lease termination fees related primarily to a reimbursement for capital expenditures made in connection with the delivery of an initial deployment for a customer that subsequently migrated from that location to another CyrusOne facility.

Net income was $43.5 million for the first quarter, compared to net loss of $30.4 million in the same period in 2017. Net income for the first quarter included a $40.5 million unrealized gain on the Company’s equity investment in GDS due to an increase in GDS’s share price during the quarter. Net income per basic and diluted common share¹ was $0.45 in the first quarter of 2018, compared to net loss of $(0.36) per basic and diluted common share in the same period in 2017.

Net operating income (NOI)² was $128.8 million for the first quarter, compared to $97.0 million in the same period in 2017, an increase of 33%. Adjusted EBITDA³ was $109.5 million for the first quarter, compared to $80.7 million in the same period in 2017, an increase of 36%.

Normalized Funds From Operations (Normalized FFO)⁴ was $82.2 million for the first quarter, compared to $61.2 million in the same period in 2017, an increase of 34%. Normalized FFO per basic and diluted common share was $0.85 in the first quarter of 2018, an increase of 18% over first quarter 2017.

Leasing Activity

CyrusOne leased approximately 29 MW of power and 226,000 CSF in the first quarter, representing $3.4 million in monthly recurring rent, inclusive of the monthly impact of installation charges, or approximately $40.4 million in annualized GAAP revenue⁵, excluding estimates for pass-through power. This excludes the impact of leases signed by Zenium in the first quarter. The weighted average lease term of the new leases, based on square footage, is 77 months (6.4 years), and the weighted average remaining lease term of CyrusOne’s portfolio is 53 months (taking into account the impact of the backlog). Recurring rent churn⁶ for the first quarter was 0.5%, compared to 1.4% for the same period in 2017.

Portfolio Development and CSF Leased

In the first quarter, the Company completed construction on 82,000 CSF and 27 MW of power capacity across four projects in Dallas, Northern Virginia, Phoenix and Austin, increasing total CSF across 45 data centers to approximately 3.35 million CSF. CSF leased⁷ as of the end of the first quarter was 92% for stabilized properties⁸ and 86% overall. In addition, the Company has development projects underway in Dallas, Northern Virginia, San Antonio, Phoenix, the New York Metro area, and Chicago that are expected to add approximately 132,000 CSF and 36 MW of power capacity.

Balance Sheet and Liquidity

As of March 31, 2018, the Company had gross assets⁹ totaling approximately $5.3 billion, an increase of approximately 28% over gross assets as of March 31, 2017. CyrusOne had $2.20 billion of long-term debt¹⁰, cash and cash equivalents of $228.7 million, and $1.7 billion available under its unsecured revolving credit facility as of March 31, 2018. Net debt¹⁰ was $1.99 billion as of March 31, 2018, representing approximately 28% of the Company's total enterprise value as of March 31, 2018 of $7.1 billion, or 4.5x Adjusted EBITDA for the last quarter annualized. Available liquidity¹¹ was $2.22 billion as of March 31, 2018.

As previously announced, CyrusOne entered into a new senior unsecured credit agreement in the first quarter, increasing the size of the credit facility by $1.0 billion, or 50%, to a total of $3.0 billion. The new agreement also provides for an extension of maturity dates, reductions in interest rate margins, and enhanced flexibility in support of the Company’s international expansion plans, including the ability to borrow in non-USD currencies.

The agreement consists of a $1.7 billion revolving credit facility, which includes a $750 million multicurrency borrowing sublimit, and term loan commitments totaling $1.3 billion. The term loan commitments consist of a $1.0 billion five-year term loan, which includes a delayed draw feature allowing the Company to draw $300 million in up to three tranches over a six-month period in multiple currencies, and a new $300 million seven-year term loan. The interest rate margins applicable to the revolving credit facility and the five-year term loan based on the Company’s current leverage level have been decreased by 10 basis points to LIBOR plus 1.45% and LIBOR plus 1.40%, respectively, while the interest rate margin applicable to the seven-year term loan based on the Company’s current leverage level is LIBOR plus 1.70%. The maturity of the revolving credit facility is March 2022, and the facility includes a one-year extension option which, if exercised by the Company, would extend the final maturity to March 2023. The maturity of the five-year term loan is March 2023, and the seven-year term loan matures in March 2025. The credit agreement also contains an accordion that allows the Company to obtain up to $1 billion in additional revolving or term loan commitments.

Also in the first quarter, CyrusOne sold approximately 3.0 million shares of its common stock through its ATM equity program at an average price of $51.24, raising approximately $152 million in net equity proceeds. As of March 31, 2018, there was approximately $346 million in remaining availability under the current ATM program.

Dividend

On February 21, 2018, the Company announced a dividend of $0.46 per share of common stock for the first quarter of 2018. The dividend was paid on April 13, 2018, to stockholders of record at the close of business on March 29, 2018.

Additionally, today the Company is announcing a dividend of $0.46 per share of common stock for the second quarter of 2018. The dividend will be paid on July 13, 2018, to stockholders of record at the close of business on June 29, 2018.

Guidance

Adoption of New Accounting Standard and Use of Non-GAAP Financial Measurements

On January 1, 2018, we adopted the new accounting standard with respect to revenue recognition, see “Note 2. Summary of Significant Accounting Policies” in our financial statements included on Form 10-Q for additional information. We have adopted the new standard using the modified retroactive transition method, where financial statement presentations prior to the date of adoption are not adjusted. Accordingly, all information related to periods prior to 2018 have not been adjusted, including non-GAAP measurements.

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, Adjusted 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 that accompany this release and are available in the Investor Relations section of www.cyrusone.com.

Management uses FFO, Normalized FFO, Adjusted EBITDA, NOI, and Adjusted NOI 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, Adjusted NOI, and Adjusted EBITDA should be considered only as supplements to net income as measures of our performance. FFO, Normalized FFO, NOI, Adjusted NOI, and Adjusted EBITDA should not be used as measures of liquidity or as indicative of funds available to fund the Company's cash needs, including the ability to pay dividends. These measures also should not be used as substitutes for cash flow from operating activities computed in accordance with U.S. GAAP.

¹Net income / (loss) per common share is defined as net income / (loss) divided by the weighted average common shares outstanding for the period, which were 96.6 million for the first quarter of 2018 (basic and diluted). The difference between basic and diluted net income per share was less than one cent.

²We use Net Operating Income ("NOI"), which is a non-GAAP financial measure commonly used in the REIT industry, as a supplemental performance measure. We use NOI as a supplemental performance measure because, when compared period over period, it captures trends in occupancy rates, rental rates and operating costs. We also believe that, as a widely recognized measure of the performance of REITs, NOI is used by investors as a basis to evaluate REITs.

We calculate NOI as revenue less property operating expenses, each of which are presented in the accompanying consolidated statements of operations. Amortization of deferred leasing costs is presented in depreciation and amortization, which is excluded from NOI. 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. However, the utility of NOI as a measure of our performance is limited. Other REITs may not calculate NOI in the same manner. Accordingly, our NOI may not be comparable to others. Therefore, NOI should be considered only as a supplement to revenue and to net income (loss) presented in accordance with GAAP as a measure of our performance. NOI should not be used as a measure of our liquidity or as indicative of funds available to fund our cash needs, including our ability to make distributions. NOI also should not be used as a supplement to or substitute for cash flow from operating activities computed in accordance with GAAP.

³Adjusted EBITDA is defined as net income (loss) as defined by U.S. GAAP plus interest expense, income tax (benefit) expense, depreciation and amortization, asset impairments and (gain) loss on disposals, stock-based compensation, transaction and integration costs, severance and management transition costs, new accounting standards and systems implementation costs, lease exit costs, legal claim costs, loss on early extinguishment of debt, unrealized (gain) on marketable equity investments and other special items. 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.

⁴We use funds from operations ("FFO") and normalized funds from operations ("Normalized FFO"), which are non-GAAP financial measures commonly used in the REIT industry, as supplemental performance measures. We use FFO and Normalized FFO as supplemental performance measures because, when compared period over period, they capture trends in occupancy rates, rental rates and operating costs. We also believe that, as widely recognized measures of the performance of REITs, FFO and Normalized FFO are used by investors as a basis to evaluate REITs. We calculate FFO as net income (loss) computed in accordance with GAAP before real estate depreciation and amortization and asset impairments and gain or loss on disposal. While it is consistent with the definition of FFO promulgated by the National Association of Real Estate Investment Trusts ("NAREIT"), our computation of FFO may differ from the methodology for calculating FFO used by other REITs. Accordingly, our FFO may not be comparable to others.

We calculate Normalized FFO as FFO plus amortization of customer relationship intangibles, transaction acquisition and other integration costs, legal claim costs and lease exit costs, and other special items including loss on early extinguishment of debt, new accounting standards and system implementation costs, and severance and management transition costs, as appropriate. Because the value of the customer relationship intangibles is inextricably connected to the real estate acquired, the Company believes the amortization of such intangibles 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. The Company believes its Normalized FFO calculation provides a comparable measure to that used by others in the industry. Other REITs may not calculate Normalized FFO in the same manner. Accordingly, our Normalized FFO may not be comparable to others.

In addition, because FFO and Normalized FFO exclude real estate depreciation and amortization and real estate impairments, and capture neither the changes in the value of our properties that result from use or from market conditions, nor the level of capital expenditures and leasing commissions necessary to maintain the operating performance of our properties, all of which have real economic effect and could materially impact our results from operations, the utility of FFO and Normalized FFO as measures of our performance is limited. Therefore, FFO and Normalized FFO should be considered only as supplements to net income (loss) presented in accordance with GAAP as measures of our performance. FFO and Normalized FFO should not be used as measures of our liquidity or as indicative of funds available to fund our cash needs, including our ability to make distributions. FFO and Normalized FFO also should not be used as supplements to or substitutes for cash flow from operating activities computed in accordance with GAAP.

⁵Annualized GAAP revenue is equal to monthly recurring rent, defined as average monthly contractual rent during the term of the lease plus the monthly impact of installation charges, multiplied by 12. It can be shown both inclusive and exclusive of the Company’s estimate of customer reimbursements for metered power.

⁶Recurring rent churn is calculated as any reduction in recurring rent due to customer terminations, service reductions or net pricing decreases as a percentage of rent at the beginning of the period, excluding any impact from metered power reimbursements or other usage-based billing.

⁷CSF leased is calculated by dividing CSF under signed leases for available space (whether or not the contract has commenced billing) by total CSF. CSF Leased differs from CSF Occupied presented in the Data Center Portfolio table because the leased rate includes CSF for signed leases that have not commenced billing.

⁸Stabilized properties include data halls that have been in service for at least 24 months or are at least 85% leased.

⁹Gross asset value is defined as total assets plus accumulated depreciation.

¹⁰Long-term debt and net debt exclude adjustments for deferred financing costs and bond premiums. Net 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 and cash equivalents.

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

(a)

We calculate Earnings Before Interest, Taxes, Depreciation and Amortization for Real Estate (EBITDAre) as GAAP net income (loss) plus interest expense, income tax expense, depreciation and amortization plus or minus losses and gains on the disposition of depreciable property, plus asset impairments. While it is consistent with the definition of EBITDAre promulgated by the National Association of Real Estate Investment Trusts ("NAREIT"), our computation of EBITDAre may differ from the methodology for calculating EBITDAre used by other REITs. Accordingly, our EBITDAre may not be comparable to others.

(a)	Straight line rent adjustments:
	Represents the difference between revenue recognized on a straight line basis under U.S. GAAP over the term of the lease compared to the contractual rental payments. Lease agreements typically include payments that escalate over the term of the contract or, to a lesser extent, a ramp period.
(b)	Deferred revenue, primarily installation revenue:
	Represents payments received from customers in excess of revenue recognized under U.S. GAAP. This primarily relates to specific customer-requested buildouts that CyrusOne does not include in its basic data center design. The company charges customers up front for these buildouts rather than incorporating into rent and billing them over time. The cash payments for these buildouts are non-recurring, and may vary significantly from quarter to quarter, but revenue is amortized over the life of the lease.

*	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 is 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 Cincinnati - 7th Street 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)	Stabilized properties include data halls that have been in service for at least 24 months or are at least 85% leased. Pre-stabilized properties include data halls that have been in service for less than 24 months and are less than 85% leased.
(c)	Represents monthly contractual rent (defined as cash rent including customer reimbursements for metered power) under existing customer leases as of March 31, 2018, multiplied by 12. For the month of March 2018, customer reimbursements were $80.6 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, 2016 through March 31, 2018, customer reimbursements under leases with separately metered power constituted between 10.2% and 12.6% of annualized rent. After giving effect to abatements, free rent and other straight-line adjustments, our annualized effective rent as of March 31, 2018 was $707.7 million. Our annualized effective rent was greater than our annualized rent as of March 31, 2018 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)	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.
(e)	Percent occupied is determined based on CSF billed to customers under signed leases as of March 31, 2018 divided by total CSF. Leases signed but that have not commenced billing as of March 31, 2018 are not included.
(f)	Percent leased is calculated by dividing CSF under signed leases for colocation space (whether or not the lease has commenced billing) by total CSF.
(g)	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.
(h)	Percent occupied is determined based on Office & Other space being billed to customers under signed leases as of March 31, 2018 divided by total Office & Other space. Leases signed but not commenced as of March 31, 2018 are not included.
(i)	Represents infrastructure support space, including mechanical, telecommunications and utility rooms, as well as building common areas.
(j)	Represents the NRSF at an operating facility that is currently leased or readily available for lease. This excludes existing vacant space held for development.
(k)	Represents space that is under roof that could be developed in the future for operating NRSF, rounded to the nearest 1,000.
(l)	Critical load capacity represents the aggregate power available for lease and exclusive use by customers expressed in terms of megawatts. The capacity reported is for non-redundant megawatts, as we can develop flexible solutions to our customers at multiple resiliency levels. Does not sum to total due to rounding.

(a)	Customers and their affiliates are consolidated.
(b)	Represents monthly contractual rent (defined as cash rent including customer reimbursements for metered power) under existing customer leases as of March 31, 2018, multiplied by 12. For the month of March 2018, customer reimbursements were $80.6 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, 2016 through March 31, 2018, customer reimbursements under leases with separately metered power constituted between 10.2% and 12.6% of annualized rent. After giving effect to abatements, free rent and other straight-line adjustments, our annualized effective rent as of March 31, 2018 was $707.7 million. Our annualized effective rent was greater than our annualized rent as of March 31, 2018 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, 2018, which was approximately $695.9 million.
(d)	Weighted average based on customer’s percentage of total annualized rent expiring and is as of March 31, 2018, 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.

A customer’s leased NRSF is estimated based on such customer’s direct CSF or office and light-industrial space plus management’s estimate of infrastructure support space, including mechanical, telecommunications and utility rooms, as well as building common areas.
(d)	Represents monthly contractual rent (defined as cash rent including customer reimbursements for metered power) under existing customer leases as of March 31, 2018, multiplied by 12. For the month of March 2018, customer reimbursements were $80.6 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, 2016 through March 31, 2018, customer reimbursements under leases with separately metered power constituted between 10.2% and 12.6% of annualized rent. After giving effect to abatements, free rent and other straight-line adjustments, our annualized effective rent as of March 31, 2018 was $707.7 million. Our annualized effective rent was greater than our annualized rent as of March 31, 2018 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.
