“We had another very strong year with high growth rates across our financial metrics and significant leasing contributions from many industry verticals and product types across almost all of our locations, with our business becoming increasingly diversified” said Gary Wojtaszek, president and chief executive officer of CyrusOne. “This was a transformative year for the company, as our European expansion positions us to better support our customers’ global requirements, while achieving investment grade status ensures access to capital at attractive rates to allow us to continue to grow with these customers in the coming years.” 

Fourth Quarter 2019 Financial Results

Revenue was $253.9 million for the fourth quarter, compared to $221.3 million for the same period in 2018, an increase of 15%.The increase in revenue was driven primarily by a 6% increase in occupied CSF, lease termination fees totaling $4.7 million and additional interconnection services.

Net loss was $(52.1) million for the fourth quarter, compared to net loss of $(105.8) million in the same period in 2018. Net loss for the fourth quarter included a $71.8 million loss on extinguishment of debt related to the repurchase or early redemption of the 5.000% Senior Notes due 2024 and the 5.375% Senior Notes due 2027. The notes were replaced by new notes, decreasing the weighted average coupon by approximately 200 basis points. Additionally, the Company recognized a $13.0 million loss associated with a change in fair value on the undesignated portion of its cross-currency swaps. Net loss per diluted common share³ was $(0.46) in the fourth quarter of 2019, compared to net loss per diluted common share of $(1.00) in the same period in 2018.

Net operating income (“NOI”)⁴ was $160.1 million for the fourth quarter, compared to $143.3 million in the same period in 2018, an increase of 12%. Adjusted EBITDA⁵ was $137.9 million for the fourth quarter, compared to $121.2 million in the same period in 2018, an increase of 14%.

Normalized Funds From Operations (“Normalized FFO”)⁶ was $113.7 million for the fourth quarter, compared to $90.9 million in the same period in 2018, an increase of 25%. Normalized FFO per diluted common share was $0.99 in the fourth quarter of 2019, compared to $0.86 in the same period in 2018, an increase of 15%.

Leasing Activity

CyrusOne leased approximately 5 MW of power and 28,000 CSF in the fourth quarter, representing approximately $1.1 million in monthly recurring rent, inclusive of the monthly impact of installation charges. The leasing for the quarter represents approximately $12.8 million in annualized GAAP revenue⁷, excluding estimates for pass-through power. The weighted average lease term of the new leases, based on square footage, is 55 months (4.6 years), and the weighted average remaining lease term of CyrusOne’s portfolio is 53 months (taking into consideration the impact of the backlog). Recurring rent churn percentage⁸ for the fourth quarter was 0.7%, compared to 0.8% for the same period in 2018.

Portfolio Development and Percentage CSF Leased

In the fourth quarter, the Company completed construction on 18,000 CSF and 10 MW of power capacity across three projects in the New York Metro area, Dallas and Northern Virginia. Percentage CSF leased⁹ as of the end of the fourth quarter was 88% for stabilized properties¹⁰ and 85% overall. In addition, the Company has development projects underway in Frankfurt, Dublin, Amsterdam, London, San Antonio, Northern Virginia, Council Bluffs (IA), and Raleigh-Durham that are expected to add approximately 380,000 CSF and 92 MW of power capacity.

Balance Sheet and Liquidity

As of December 31, 2019, the Company had gross asset value¹¹ totaling approximately $7.5 billion, an increase of approximately 13% over gross asset value as of December 31, 2018. CyrusOne had $2.92 billion of long-term debt¹², $76.4 million of cash and cash equivalents, and $1.08 billion available under its unsecured revolving credit facility as of December 31, 2019. Net debt¹² was $2.87 billion as of December 31, 2019, representing approximately 28% of the Company's total enterprise value as of December 31, 2019 of $10.4 billion, or 5.0x Adjusted EBITDA for the last quarter annualized (after further adjusting net debt to reflect the pro forma impact of settlement of the forward sale agreement). After further adjusting Adjusted EBITDA to exclude the impact of the adoption of ASC 842 as of January 1, 2019, in order to present the leverage metric on a basis comparable to that of periods prior to 2019, net debt to Adjusted EBITDA for the last quarter annualized was 4.9x¹³. Available liquidity¹⁴ was $1.25 billion as of December 31, 2019.

The Company issued $600 million of 2.90% Senior Notes due 2024 and $600 million of 3.45% Senior Notes due 2029, replacing the Company’s previously outstanding senior notes and decreasing the weighted average coupon by approximately 200 basis points.

Additionally, subsequent to the end of the quarter, the Company issued €500 million of 1.45% Senior Notes due 2027, with the proceeds used to repay floating rate Euro denominated obligations and fund continued development in Europe. As adjusted for the Euro notes offering, the Company’s weighted average remaining debt term as of December 31, 2019 was approximately 5.8 years, and it had $1.56 billion available under its unsecured revolving credit facility.

The Company raised approximately $104 million in net proceeds through the sale of approximately 1.6 million shares of common stock under its ATM equity program. Additionally, through the ATM equity program, the Company entered into a forward sale agreement with respect to an additional 1.6 million shares, which will result in estimated net proceeds of approximately $99 million upon settlement by November 2020 (no portion of this forward sale agreement has been settled as of February 19, 2020). As of December 31, 2019, there was approximately $290 million in remaining availability under the current ATM equity program.

Dividend

On October 30, 2019, the Company announced a dividend of $0.50 per share of common stock for the fourth quarter of 2019. The dividend was paid on January 10, 2020, to stockholders of record at the close of business on January 2, 2020.

Adoption of New Accounting Standard and Use of Non-GAAP Financial Measures and Other Metrics

In February 2016, the Financial Accounting Standards Board issued ASU 2016-02 (codified in ASC 842, Leases (“ASC 842”)) to increase transparency and comparability among organizations by recognizing lease assets and lease liabilities on the balance sheet and disclosing key information about leasing transactions. The ASU requires that a liability be recorded on the balance sheet for all leases where the reporting entity is a lessee, based on the present value of future lease obligations. A corresponding right-of-use asset will also be recorded. Amortization of the lease obligation and the right-of-use asset for leases classified as operating leases are on a straight-line basis. Leases classified as financing leases are required to be accounted for as financing arrangements similar to the accounting treatment for capital leases under ASC 840, Leases(the former accounting standard for all leases).

We adopted ASU 2016-02 on January 1, 2019, applied the package of practical expedients included therein and utilized the modified retrospective transition method with the cumulative effect of transition recognized on the effective date. By applying the modified retrospective transition method, the presentation of financial information for periods prior to January 1, 2019 was not restated.

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, Normalized Funds From Operations per Diluted Common Share, Adjusted EBITDA, Net Operating Income, and Net Debt should not be construed as being more important than, or a substitute for, 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, Normalized FFO per Diluted Common Share, Adjusted EBITDA, and NOI, which are non-GAAP financial measures commonly used in the REIT industry, as supplemental performance measures. Management uses these measures as supplemental performance measures because, when compared period over period, they 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), these measures are used by investors as a basis to evaluate REITs. 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, and Adjusted EBITDA should be considered only as supplements to net income as measures of our performance. FFO, Normalized FFO, 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 make distributions. These measures also should not be used as supplements to or substitutes for cash flow from operating activities computed in accordance with GAAP. The Company believes that Net Debt provides a useful measure of liquidity and financial health.

¹ The Company adopted ASC 842 effective January 1, 2019. The adjusted 4Q’18 and FY‘18 results have not been prepared in accordance with GAAP and represent the Company’s estimates as if the standard had been adopted as of January 1, 2018. The percentage changes versus adjusted 4Q’18 and FY’18 results are being shown solely for comparative and investor usefulness purposes with respect to the Company’s 4Q’19 and FY’19 results, respectively. There is no impact on 4Q’18 Revenue or FY’18 Revenue. The estimated impacts on 4Q’18 Net income (loss), Adjusted EBITDA, Normalized FFO, Net income / (loss) per diluted share, and Normalized FFO per diluted share are $1.5 million, $4.5 million, $2.6 million, $0.01, and $0.02, respectively. The estimated impacts on FY’18 Net income (loss), Adjusted EBITDA, Normalized FFO, Net income / (loss) per diluted share, and Normalized FFO per diluted share are $5.4 million, $17.2 million, $9.4 million, $0.05, and $0.09, respectively.

²Inclusive of 4.5 MW and approximately $5.5 million in annualized GAAP revenue associated with a paid reservation signed in 3Q’19 expected to be exercised in the next nine months.

³Net income (loss) per diluted common share is defined as net income (loss) divided by the weighted average diluted common shares outstanding for the period, which were 114.4 million for the fourth quarter of 2019 and 105.5 million for the fourth quarter of 2018.

⁴We 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 expenses. 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 net income (loss), adjusted for sales and marketing expenses, general and administrative expenses, depreciation and amortization expenses, transaction, acquisition, integration and other related expenses, interest expense, net, (gain) loss on marketable equity investment, loss on early extinguishment of debt, impairment losses, gain on asset disposals, foreign currency and derivative losses, net, other expense and income tax (benefit) expense. Amortization of deferred leasing costs is presented in depreciation and amortization expenses, which is excluded from NOI. Sales and marketing expenses are not property-specific, rather these expenses support our entire portfolio. As a result, we have excluded these sales and marketing expenses from our NOI calculation, consistent with the treatment of general and administrative expenses, which also support our entire portfolio. Because the calculation of NOI excludes various expenses, 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 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.

⁵Adjusted EBITDA, which is a non-GAAP financial measure, is defined as net income (loss) as defined by GAAP adjusted for interest expense, net; income tax (benefit) expense; depreciation and amortization; impairment losses; transaction, acquisition, integration and other related expenses; legal claim costs; stock-based compensation expense; severance and management transition costs; loss on early extinguishment of debt; new accounting standards and regulatory compliance and the related system implementation costs; (gain) loss on marketable equity investment; (gain) loss on asset disposals; foreign currency and derivative losses (gains), net; and other expense. 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.

⁶We 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 impairment losses and loss on disposal of assets. 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 loss on early extinguishment of debt; (gain) loss on marketable equity investment; foreign currency and derivative losses (gains), net; new accounting standards and regulatory compliance and the related system implementation costs; amortization of tradenames; transaction, acquisition, integration and other related expenses; severance and management transition costs; and legal claim costs. We believe our Normalized FFO calculation provides a comparable measure between different periods. Other REITs may not calculate Normalized FFO in the same manner. Accordingly, our Normalized FFO may not be comparable to others.

7

In addition, because FFO and Normalized FFO exclude real estate depreciation and amortization, 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.

⁷Annualized 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.

⁸Recurring rent churn percentage 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.

⁹Percentage CSF leased is calculated by dividing CSF under signed leases for colocation space (whether or not the lease has commenced billing) by total CSF. Percentage 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.

¹⁰Stabilized properties include data halls that have been in service for at least 24 months or are at least 85% leased.

¹¹Gross asset value is defined as total assets plus accumulated depreciation.

¹²Long-term debt and net debt exclude adjustments for deferred financing costs and bond premiums. Net debt, which is a non-GAAP financial measure, provides a useful measure of liquidity and financial health. The Company defines net debt as long-term debt and finance lease liabilities, offset by cash and cash equivalents.

¹³The estimated impact of the adoption of ASC 842 on Adjusted EBITDA for the last quarter annualized is $16.2 million.

¹⁴Liquidity is calculated as cash, cash equivalents, and temporary cash investments on hand, plus the undrawn capacity on CyrusOne’s revolving credit facility, plus the pro forma impact of settlement of the forward sale agreement.

(a) We calculate Earnings Before Interest, Taxes, Depreciation and Amortization for Real Estate (EBITDAre) as GAAP net income (loss) plus interest expense, income tax benefit (expense), depreciation and amortization and impairment losses. 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 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 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, 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 December 31, 2019 multiplied by 12. For the month of December 2019, customer reimbursements were $137.6 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 January 1, 2018 through December 31, 2019, customer reimbursements under leases with separately metered power constituted between 11.6% and 19.4% of annualized rent. After giving effect to abatements, free rent and other straight-line adjustments, our annualized effective rent as of December 31, 2019 was $906.7 million. Our annualized effective rent was lower than our annualized rent as of December 31, 2019 because our negative straight-line and other adjustments and amortization of deferred revenue exceeded our positive straight-line adjustments due to factors such as the timing of contractual rent escalations and customer payments 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 December 31, 2019 divided by total CSF. Leases signed but that have not commenced billing as of December 31, 2019 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 December 31, 2019 divided by total Office & Other space. Leases signed but not commenced as of December 31, 2019 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 December 31, 2019, multiplied by 12. For the month of December 2019, customer reimbursements were $137.6 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 January 1, 2018 through December 31, 2019, customer reimbursements under leases with separately metered power constituted between 11.6% and 19.4% of annualized rent. After giving effect to abatements, free rent and other straight-line adjustments, our annualized effective rent as of December 31, 2019 was $906.7 million. Our annualized effective rent was lower than our annualized rent as of December 31, 2019 because our negative straight-line and other adjustments and amortization of deferred revenue exceeded our positive straight-line adjustments due to factors such as the timing of contractual rent escalations and customer payments for services.

(c) Represents the customer’s total annualized rent divided by the total annualized rent in the portfolio as of December 31, 2019, which was approximately $916.8 million.

(d) Weighted average based on customer’s percentage of total annualized rent expiring and is as of December 31, 2019, 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.
