Forward Looking Statements

Some of the statements contained in this document constitute forward-looking statements within the meaning of the federal securities laws. Forward-looking statements relate to expectations, beliefs, projections, future plans and strategies, anticipated events or trends and similar expressions concerning matters that are not historical facts. In particular, statements pertaining to the Company’s capital resources, portfolio performance, results of operations, anticipated growth in our funds from operations and anticipated market conditions contain forward-looking statements. In some cases, you can identify forward-looking statements by the use of forward-looking terminology such as “may,” “will,” “should,” “expects,” “intends,” “plans,” “anticipates,” “believes,” “estimates,” “predicts,” or “potential” or the negative of these words and phrases or similar words or phrases which are predictions of or indicate future events or trends and which do not relate solely to historical matters. You also can identify forward-looking statements by discussions of strategy, plans or intentions.

The forward-looking statements contained in this document reflect the Company’s current views about future events and are subject to numerous known and unknown risks, uncertainties, assumptions and changes in circumstances that may cause actual results to differ significantly from those expressed in any forward-looking statement. The Company does not guarantee that the transactions and events described will happen as described (or that they will happen at all). The following factors, among others, could cause actual results and future events to differ materially from those set forth or contemplated in the forward-looking statements: adverse economic or real estate developments in the Company’s markets or the technology industry; obsolescence or reduction in marketability of our infrastructure due to changing industry demands; global, national and local economic conditions; our ability to successfully execute our strategic growth plan and realize its expected benefits; risks related to our international operations; difficulties in identifying properties to acquire and completing acquisitions; the Company’s failure to successfully develop, redevelop and operate acquired properties or lines of business; significant increases in construction and development costs; the increasingly competitive environment in which the Company operates; defaults on, or termination or non-renewal of, leases by customers; decreased rental rates or increased vacancy rates; increased interest rates and operating costs, including increased energy costs; financing risks, including the Company’s failure to obtain necessary outside financing; dependence on third parties to provide Internet, telecommunications and network connectivity to the Company’s data centers; the Company’s failure to qualify and maintain its qualification as a real estate investment trust; environmental uncertainties and risks related to natural disasters; financial market fluctuations; and changes in real estate and zoning laws, revaluations for tax purposes and increases in real property tax rates.

While forward-looking statements reflect the Company’s good faith beliefs, they are not guarantees of future performance. Any forward-looking statements speak only as of the date on which they were made. The Company disclaims any obligation to publicly update or revise any forward-looking statement to reflect changes in underlying assumptions or factors, of new information, data or methods, future events or other changes. For a further discussion of these and other factors that could cause the Company’s future results to differ materially from any forward-looking statements, see the section entitled “Risk Factors” in the Company’s Annual Report on Form 10-K for the year ended December 31, 2017 and other periodic reports the Company files with the Securities and Exchange Commission.

Summary of Financial Data

(unaudited and in thousands, except operating portfolio statistics data and per share data)

In conjunction with its previously announced strategic growth plan, QTS is realigning its product offerings around Hyperscale and Hybrid Colocation, while exiting certain of its C3-Cloud and Managed Services offerings, as well as colocation revenue attached to certain customers in the Cloud and Managed Services business that we expect will not remain with QTS post transition (collectively “Non-Core” operations). QTS has realigned information included in this release to focus its guidance and key performance metrics around its Core business, which primarily consists of its Hyperscale and Hybrid Colocation businesses, along with technology and services from its Cloud and Managed Services business that support Hyperscale and Hybrid Colocation customers, which together will be the Company’s primary business following the completion of the strategic growth plan. For informational purposes, QTS has excluded its estimated Non-Core business from certain financial and operating statistics below. A more detailed allocation of Core and Non-Core financial information is presented in the Appendix.

This summary includes certain non-GAAP financial measures that management believes are helpful in understanding the Company’s business, including its core business, as further described in the Appendix. The Company does not, nor does it suggest investors should, consider such non-GAAP financial measures in isolation from, or as a substitute for, GAAP financial information or as an expectation of future performance of the Company’s core business. The Company believes that the presentation of non-GAAP financial measures provide meaningful supplemental information to both management and investors that is indicative of the Company’s current operations and its core business. The Company has included a reconciliation of this additional information to the most comparable GAAP measure in the selected financial information below.

2018 Core Guidance 

References to QTS’ “Core” business refers to the Company’s business expected to be retained following the completion of the previously announced strategic growth plan, as further described in the Appendix. The Company is reaffirming its 2018 guidance, as outlined below. 

	2018 (1)
($ in millions except per share amounts)	Low		High
Core Revenue	$	408	$	422
Core Adjusted EBITDA	$	218	$	228
Core Operating FFO per fully diluted share	$	2.55	$	2.65
Capital Expenditures (2)	$	425	$	475

(1) Guidance for the year ended December 31, 2018 excludes results from the Non-Core business unit.

(2) Reflects consolidated cash capital expenditures and excludes expenditures from acquisitions.

The Company expects annual rental churn for the Core business of 3% to 6%. The Company expects capital expenditures of $425 million to $475 million, front end loaded in 2018 related to new development in Ashburn, VA and excluding additional success based development in Hillsboro, OR and Phoenix, AZ.

QTS does not provide reconciliations for the non-GAAP financial measures included in its guidance provided above due to the inherent difficulty in forecasting and quantifying certain amounts that are necessary for such reconciliations, including net income (loss) and adjustments that could be made for restructuring costs, transaction costs, lease exit costs, asset impairments and loss on disposals and other charges as those amounts are subject to significant variability based on future transactions that are not yet known, the amount of which, based on historical experience, could be significant.

Reconciliations of Core Return on Invested Capital (ROIC)

(unaudited and in thousands)

Core Return on Invested Capital (“ROIC”) is a non-GAAP measure that provides additional information to users of the financial statements. Management believes Core ROIC is a helpful metric for users of the financial statements to gauge the Company's performance of its Core business against the capital it has invested in the Core business.

(1) Includes facility level G&A expense allocation charges of 4% of cash revenue for all facilities, with the exception of the leased facilities acquired in 2015, which include G&A expense allocation charges of 10% of cash revenue. These allocated charges, with respect to Core operations,  aggregated to $4.2 million, $4.3 million and $3.8 million for the three months ended March 31, 2018,  December 31, 2017 and March 31, 2017 respectively.

(2) Calculated using Core amounts only. Had the amounts included Non-Core assets and Non-Core NOI, consolidated annualized ROIC for the three months ended March 31, 2018, December 31, 2017 and March 31, 2017 would be 13.5%, 14.3% and 13.8%,  respectively.

Core NOI by Facility and Consolidated Capital Expenditure Summary

(unaudited and in thousands)

The Company calculates Core net operating income, or Core NOI, as net income (loss), excluding: interest expense, interest income, tax expense (benefit) of taxable REIT subsidiaries, depreciation and amortization, write-off of unamortized deferred financing costs, gain (loss) on extinguishment of debt, transaction and integration costs, gain (loss) on sale of real estate, restructuring costs and general and administrative expenses, in each case attributable to the Company’s Core business. The Company believes that core NOI is another metric that is often utilized to evaluate returns on operating real estate from period to period and also, in part, to assess the value of the operating real estate.

Core NOI was calculated in the following manner: For revenue, QTS identified the specific products that it expects to divest of in 2018 and allocated the specific revenue to Non-Core operations. For customers that had Non-Core managed service revenue and also had colocation revenue, the Company performed an analysis on a customer-by-customer basis to determine colocation revenue attached to certain customers in the Cloud and Managed Services business that we expect will not remain with QTS post transition.For operating costs, the Company identified costs such as rent expense and repairs and maintenance costs associated with servicing the aforementioned Non-Core revenue and classified those costs as Non-Core. The breakdown of Core NOI by facility is shown below:

Leasing Statistics – Core Signed Leases

The mix of leasing activity has a significant impact on quarterly rates, both within major product segments and for overall blended leasing rates. The pricing on new and modified leases signed varies quarter to quarter based on the mix of Core deals leased as Hyperscale and Hybrid Colocation vary on a rate per square foot basis. The amounts below include renewals when there was a change in square footage rented, but exclude renewals where square footage remained consistent before and after renewal. (See renewal table on page 17 for such renewals). The amounts below also exclude leases signed related to Non-Core products and services.  

During the first quarter of 2018, the Company entered into 413 new and modified Core leases aggregating to $36.0 million of annualized rent which includes new leased revenue plus revenue from modified renewals. Removing non-incremental annualized MRR from modified renewals and deducting downgrades during the period resulted in $21.0 million in Core incremental annualized rent for the quarter ended March 31, 2018.  Pricing on new and modified leases signed during the first quarter was lower than the prior four quarter average, which was driven by a higher proportion of larger footprint deals compared to prior periods. 

Annualized rent per leased square foot is computed using the total rent associated with all new and modified Core leases for the respective periods. Incremental Annualized Rent, Net of Downgrades reflects net incremental MRR signed during the period for purposes of tracking incremental revenue contribution.

	Period	Number of Leases	Total Leased sq ft		Annualized rent per leased sq ft (1)		Annualized Rent of New and Modified Leases		Incremental Annualized Rent, Net of Downgrades(2)
New/modified leases signed - Core (3)	Q1 2018	413	90,294	$	399	$	35,982,816	$	21,039,069

	Q1 2017	318	17,631		737		13,002,156		3,662,659

* Average of prior 4 quarters

(1) Calculated using all Core revenue including new lease MRR and modified renewal MRR.

(2) Amounts include  Core incremental MRR only, net of downgrades.

(3) Includes leases of Core products only. Had the incremental annualized rent, net of downgrades included Non-Core leases, consolidated incremental annualized rent net of downgrades would be $16,735,105,  $8,719,465,  $15,329,139, $13,134,696, and $4,333,697 for the three months ended March 31, 2018, December 31, 2017, September 30, 2017, June 30, 2017 and March 31, 2017, respectively, and the prior four quarter average would be $10,379,249.

NOTE: Figures above do not include cost recoveries.

The following table outlines the Core booked-not-billed (“BNB”) balance as of March 31, 2018 and how that will affect revenue in 2018 and subsequent years:

Core Booked-not-billed ("BNB")	2018		2019		Thereafter		Total
Core MRR	$	2,094,542	$	1,440,757	$	960,132	$	4,495,431
Core incremental revenue (1)		14,750,532		13,390,918		11,521,584
Core annualized revenue (2)		25,134,504		17,289,084		11,521,584		53,945,172

(1) Core incremental revenue represents the expected amount of recognized MRR for the Core business in the period based on when the Core booked-not-billed leases commence throughout the period.

(2) Core annualized revenue represents the Core booked-not-billed MRR multiplied by 12, demonstrating how much recognized MRR for the Core business might have been recognized if the Core booked-not-billed leases commencing in the period were in place for an entire year.    Had the BNB annualized revenue included Non-Core leases, consolidated annualized BNB revenue would be $57,368,640.

The Company estimates the remaining cost to provide the space, power, connectivity and other services to the customer contracts which had not billed as of March 31, 2018 to be approximately $106 million. This estimate generally includes customers with newly contracted space of more than 3,300 square feet of raised floor space. The space, power, connectivity and other services provided to customers that contract for smaller amounts of space is generally provided by existing space which was previously developed.

Leasing Statistics – Core Renewed and Commenced Leases and Core Rental Churn 

The mix of leasing activity has a significant impact on quarterly rates, both within major product segments and for overall blended renewal rates. The Company’s rate performance will vary quarter to quarter based on the mix of Core deals leased as Hyperscale and Hybrid Colocation vary on a rate per square foot basis.

Consistent with the Company’s strategy and business model, the renewal rates below reflect total Core MRR per square foot including all subscribed services. The amounts below exclude leases of Non-Core products. For comparability, the Company includes only those customers that have maintained consistent space footprints in the computations below. All customers with space changes are incorporated into new/modified leasing statistics and rates.

The overall blended rate for  Core renewals signed in the first quarter of 2018 was 5.4% higher than the rates for those customers immediately prior to renewal. The Company expects renewal rates will generally increase in the low to mid-single digits.

Core Rental Churn (which the Company defines as Core MRR lost in the period to a customer intending to fully exit the QTS platform in the near term compared to total Core MRR at the beginning of the period) was 1.0% for the first quarter of 2018.  Consolidated Rental Churn (which the Company defines as consolidated MRR lost in the period to a customer intending to fully exit the QTS platform in the near term compared to consolidated MRR at the beginning of the period) was 1.8% for the first quarter of 2018.

(2) Includes leases of Core products only.  Had the rent change percentage included Non-Core leases, consolidated rent changes would be 5.3%, 1.2%, 2.1%, 1.0%, and 2.6% for the three months ended March 31, 2018, December 31, 2017, September 30, 2017, June 30, 2017 and March 31, 2017, respectively, and 1.5% for the prior four quarter average.

The mix of leasing activity has a significant impact on quarterly rates, both within major product segments and for overall blended commencement rates. The Company’s rate performance will vary quarter to quarter based on the mix of Core deals leased as Hyperscale and Hybrid Colocation vary on a rate per square foot basis.

During the first quarter of 2018, the Company commenced customer leases (which includes both new customers and existing customers that renewed their lease terms) representing approximately $29.8 million of annualized Core rent at $529 per square foot. This compares to customer leases representing an aggregate trailing four quarter average of approximately $23.1 million of annualized Core rent at $480 per square foot.Average pricing on Core commenced leases during the first quarter of 2018 increased compared to the prior four quarter average primarily due to a higher proportion of smaller footprint hybrid colocation deals.

Core Lease Expirations

Lease expirations information is presented below for the Core business, which primarily consists of the Company’s Hyperscale and Hybrid Colocation businesses, along with technology and services from its Cloud and Managed Services business that support Hyperscale and Hybrid Colocation customers.  Hyperscale leases are typically 5-10 years with the majority of Hyperscale lease expirations occurring in 2022 and beyond. Hybrid Colocation leases are typically 3 years in duration, with the majority of Hybrid Colocation lease expirations occurring in 2018 and 2019. The following table sets forth a summary schedule of the Core lease expirations as of March 31, 2018. Unless otherwise stated in the footnotes, the information set forth in the table assumes that customers exercise no renewal options and all early termination rights are exercised.  

Note: The lease expirations table below has been calculated proforma for the effects of two Hyperscale anchor tenants’ leases that were signed but not yet commenced as of March 31, 2018. As such, the annualized rent does not reconcile to reported annualized MRR in other locations of this document.

Appendix

Non-GAAP Financial Measures

This document includes certain non-GAAP financial measures that management believes are helpful in understanding the Company’s business, as further described below.

The Company considers the following non-GAAP financial measures to be useful to investors as key supplemental measures of the Company’s performance: (1) Core Revenue; (2) FFO, Operating FFO, Adjusted Operating FFO, Core Operating FFO and Adjusted Core Operating FFO (3) MRR, Recognized MRR and Core MMR; (4) NOI and Core NOI; and (5) EBITDAre, Adjusted EBITDA, Core Adjusted EBITDA. These non-GAAP financial measures should be considered along with, but not as alternatives to, net income or loss and cash flows from operating activities as a measure of the Company’s operating performance. Core Revenue, FFO, Operating FFO, Adjusted Operating FFO, MRR, NOI, EBITDA and Adjusted EBITDA, as calculated by us, including on a Core and Non-Core basis, may not be comparable to FFO, Operating FFO, Adjusted Operating FFO, MRR, NOI, EBITDA and Adjusted EBITDA as reported by other companies that do not use the same definition or implementation guidelines or interpret the standards differently from us.

Definitions

Booked-not-billed (“BNB”). The Company defines booked-not-billed as customer leases that have been signed, but for which lease payments have not yet commenced.

Core. Core represents the Company’s business expected to remain following disposition of the Company’s “Non-Core” business in accordance with its previously announced strategic growth plan. The Core business consists primarily of the Company’s Hyperscale and Hybrid Colocation business, along with technology and services from the Company’s Cloud and Managed Services business that support Hyperscale and Hybrid Colocation customers. Core financial measures and operating statistics represent the financial results or operating statistics, as applicable, of the Company’s Core business.

Leasable raised floor. The Company defines leasable raised floor as the amount of raised floor square footage that the Company has leased plus the available capacity of raised floor square footage that is in a leasable format as of a particular date and according to a particular product configuration. The amount of leasable raised floor may change even without completion of new redevelopment projects due to changes in the Company’s configuration of product space.

Non-Core. Non-core represents the portion of the Company’s business that the Company expects to exit in accordance with its previously announced strategic growth plan. The Non-Core business consists of the products of services within the Company’s Cloud and Managed Services business, as well as colocation revenue attached to certain customers in the Cloud and Managed Services business. Non-core financial measures and operating statistics represent the financial results or operating statistics, as applicable, of the Company’s Con-Core business.

Basis-of-design floor space. The Company defines basis-of-design floor space as the total data center raised floor potential of its existing data center facilities.

Operating NRSF. Represents the total square feet of a building that is currently leased or available for lease plus developed supporting infrastructure, based on engineering drawings and estimates, but does not include space held for redevelopment or space used for the Company’s own office space.

The Company. Refers to QTS Realty Trust, Inc., a Maryland corporation, together with its consolidated subsidiaries, including QualityTech, LP (the “Operating Partnership” or “OP”).

FFO, Operating FFO, Adjusted Operating FFO, Core Operating FFO and Adjusted Core Operating FFO

The Company considers funds from operations (“FFO”), to be a supplemental measure of its performance which should be considered along with, but not as an alternative to, net income (loss) and cash provided by operating activities as a measure of operating performance. The Company calculates FFO in accordance with the standards established by the National Association of Real Estate Investment Trusts (“NAREIT”). FFO represents net income (loss) (computed in accordance with GAAP), adjusted to exclude gains (or losses) from sales of property, real estate-related depreciation and amortization and similar adjustments for unconsolidated partnerships and joint ventures. The Company’s management uses FFO as a supplemental performance measure because, in excluding real estate related depreciation and amortization and gains and losses from property dispositions, it provides a performance measure that, when compared year over year, captures trends in occupancy rates, rental rates and operating costs.

Due to the volatility and nature of certain significant charges and gains recorded in the Company’s operating results that management believes are not reflective of its core operating performance, management computes an adjusted measure of FFO, which the Company refers to as Operating FFO. The Company generally calculates Operating FFO as FFO excluding certain non-routine charges and gains and losses that management believes are not indicative of the results of the Company’s operating real estate portfolio. The Company believes that Operating FFO provides investors with another financial measure that may facilitate comparisons of operating performance between periods and, to the extent other REITs calculate Operating FFO on a comparable basis, between REITs.

Operating FFO and Adjusted Operating Funds From Operations (“Adjusted Operating FFO”) are non-GAAP measures that are used as supplemental operating measures and to provide additional information to users of the financial statements. The Company calculates Adjusted Operating FFO by adding or subtracting from Operating FFO items such as: maintenance capital investment, paid leasing commissions, amortization of deferred financing costs and bond discount, non-real estate depreciation, straight line rent adjustments, deferred taxes and non-cash compensation.

The Company offers these measures because it recognizes that FFO, Operating FFO and Adjusted Operating FFO will be used by investors as a basis to compare its operating performance with that of other REITs. However, because FFO, Operating FFO and Adjusted Operating FFO exclude real estate depreciation and amortization and capture neither the changes in the value of the Company’s properties that result from use or market conditions, nor the level of capital expenditures and capitalized leasing commissions necessary to maintain the operating performance of its properties, all of which have real economic effect and could materially impact its financial condition, cash flows and results of operations, the utility of FFO, Operating FFO and Adjusted Operating FFO as measures of its operating performance is limited. The Company’s calculation of FFO may not be comparable to measures calculated by other companies who do not use the NAREIT definition of FFO or do not calculate FFO in accordance with NAREIT guidance. In addition, the Company’s calculations of FFO, Operating FFO and Adjusted Operating FFO are not necessarily comparable to FFO, Operating FFO and Adjusted Operating FFO as calculated by other REITs that do not use the same definition or implementation guidelines or interpret the standards differently from us. FFO, Operating FFO and Adjusted Operating FFO are non-GAAP measures and should not be considered a measure of the Company’s results of operations or liquidity or as a substitute for, or an alternative to, net income (loss), cash provided by operating activities or any other performance measure determined in accordance with GAAP, nor is it indicative of funds available to fund its cash needs, including its ability to make distributions to its stockholders.

Core Operating FFO and Adjusted Core Operating FFO represent Operating FFO and Adjusted Operating FFO of the Company’s Core business, respectively, and are used as supplemental performance measures because they reflect results of the portion of the business the Company expects to retain following completion of the strategic growth plan.

Monthly Recurring Revenue (MRR), Recognized MRR and Core MRR

The Company calculates MRR as monthly contractual revenue under signed leases as of a particular date, which includes revenue from its rental and cloud and managed services activities, but excludes customer recoveries, deferred set-up fees, variable related revenues, non-cash revenues and other one-time revenues. MRR does not include the impact from booked-not-billed leases as of a particular date, unless otherwise specifically noted.

Separately, the Company calculates recognized MRR as the recurring revenue recognized during a given period, which includes revenue from its rental and cloud and managed services activities, but excludes customer recoveries, deferred set up fees, variable related revenues, non-cash revenues and other one-time revenues.

Management uses MRR, recognized MRR and Core MRR as supplemental performance measures because they provide useful measures of increases in contractual revenue from the Company’s customer leases and customer leases attributable to the Company’s core business. MRR, recognized MRR and Core MRR should not be viewed by investors as alternatives to actual monthly revenue, as determined in accordance with GAAP. Other companies may not calculate MRR, recognized MRR or Core MRR in the same manner. Accordingly, the Company’s MRR, recognized MRR and Core MRR may not be comparable to other companies’ MRR, recognized MRR and Core MRR. MRR, recognized MRR and Core MRR should be considered only as supplements to total revenues as a measure of its performance. MRR, recognized MRR and Core MRR should not be used as measures of the Company’s results of operations or liquidity, nor is it indicative of funds available to meet its cash needs, including its ability to make distributions to its stockholders.

Earnings Before Interest, Taxes, Depreciation and Amortization for Real Estate (EBITDAre) and Adjusted EBITDA

The Company considers earnings before interest, taxes, depreciation and amortization for real estate (“EBITDAre”), to be a supplemental measure of its performance which should be considered along with, but not as an alternative to, net income (loss) and cash provided by operating activities as a measure of operating performance. The Company calculates EBITDAre in accordance with the standards established by the National Association of Real Estate Investment Trusts (“NAREIT”). EBITDAre represents net income (loss) (computed in accordance with GAAP), adjusted to exclude gains (or losses) from sales of depreciated property, income tax expense (or benefit), interest expense, depreciation and amortization, impairments of depreciated property and unconsolidated partnerships and joint ventures, and similar adjustments for unconsolidated partnerships and joint ventures. The Company’s management uses EBITDAre as a supplemental performance measure because it provides a performance measure that, when compared year over year, captures the performance of the Company’s operations by removing the impact of capital structure (primarily interest expense) and asset base charges (primarily depreciation and amortization), from its operating results.

Due to the volatility and nature of certain significant charges and gains recorded in the Company’s operating results that management believes are not reflective of its operating performance, management computes an adjusted measure of EBITDAre, which the Company refers to as Adjusted EBITDA. The Company generally calculates Adjusted EBITDA excluding certain non-routine charges write off of unamortized deferred financing costs, gains (losses) on extinguishment of debt, transaction and integration costs, in addition to non-cash recurring costs such as equity-based compensation. The Company believes that Adjusted EBITDA provides investors with another financial measure that may facilitate comparisons of operating performance between periods and, to the extent other REITs calculate Adjusted EBITDA on a comparable basis, between REITs.

Management uses EBITDAre and Adjusted EBITDA as supplemental performance measures as they provide useful measures of assessing the Company’s operating results. Other companies may not calculate EBITDAre or Adjusted EBITDA in the same manner. Accordingly, the Company’s EBITDAre and Adjusted EBITDA may not be comparable to others. EBITDAre and Adjusted EBITDA should be considered only as supplements to net income (loss) as measures of the Company’s performance and should not be used as substitutes for net income (loss), as measures of its results of operations or liquidity or as an indications of funds available to meet its cash needs, including its ability to make distributions to its stockholders.

Net Operating Income (NOI) and Core NOI

The Company calculates net operating income (“NOI”) as net income (loss) (computed in accordance with GAAP), excluding: interest expense, interest income, tax expense (benefit) of taxable REIT subsidiaries, depreciation and amortization, write off of unamortized deferred financing costs, gain (loss) on extinguishment of debt, transaction and integration costs, gain (loss) on sale of real estate, restructuring costs and general and administrative expenses. Management uses NOI as a supplemental performance measure because it provides a useful measure of the operating results from its customer leases. In addition, management believes it is useful to investors in evaluating and comparing the operating performance of its properties and to compute the fair value of its properties. The Company’s NOI may not be comparable to other REITs’ NOI as other REITs may not calculate NOI in the same manner. NOI should be considered only as a supplement to net income as a measure of the Company’s performance and should not be used as a measure of results of operations or liquidity or as an indication of funds available to meet cash needs, including the ability to make distributions to stockholders. NOI is a measure of the operating performance of the Company’s properties and not of the Company’s performance as a whole. Core NOI represents NOI of the Company’s core business and is used as a supplemental performance measure because it reflects results of the portion of the business the Company expects to retain following completion of the strategic growth plan. NOI and Core NOI are therefore not substitutes for net income as computed in accordance with GAAP.

Core/Non-Core Reconciliations

In conjunction with its previously announced strategic growth plan, QTS is realigning its product offerings around Hyperscale and Hybrid Colocation, while exiting certain of its C3-Cloud and Managed Services offerings, as well as colocation revenue attached to certain customers in the Cloud and Managed Services business that we expect will not remain with QTS post transition (collectively “Non-Core” operations). QTS has realigned information included in this release to focus its guidance and key performance metrics around its Core business, which primarily consists of its Hyperscale and Hybrid Colocation businesses, along with technology and services from its Cloud and Managed Services business that support Hyperscale and Hybrid Colocation customers, which together will be the Company’s primary business following the completion of the strategic growth plan.     

The table below includes certain non-GAAP financial measures, separated on a Core / Non-Core basis, which management believes is helpful to understanding the financial results of the Company’s Core business. 

In order to bifurcate revenues and costs the Company utilized the following methodology: For managed service revenue, QTS identified the specific products that it expects to divest of in 2018, and allocated their specific revenue to Non-Core operations. For customers that had Non-Core managed service revenue and also had colocation revenue, the Company performed an analysis on a customer-by-customer basis to determine the portion of colocation revenue considered to be Non-Core.

For operating costs, the Company identified costs such as rent expense, software licenses, communications expenses and repairs and maintenance costs associated with servicing the aforementioned Non-Core revenue and classified those costs as Non-Core. 

For general and administrative costs, certain personnel costs, including severance benefits and equity-based compensation, that were associated with personnel impacted by the strategic growth plan have been reclassified in the first quarter of 2018 to restructuring costs. For current and prior periods Non-Core personnel costs associated with wages and salaries were not reclassified to restructuring cost but are shown in their respective line items as Non-Core. QTS identified the software costs, communications expense and other similar general and administrative costs that are utilized to support the aforementioned revenue and reclassified those costs to Non-Core accordingly. 

Depreciation associated with equipment was identified that services the impacted customers and that QTS expects to dispose of in a transaction has been reclassified accordingly to Non-Core costs. Equipment or other capitalized costs that QTS has abandoned have been reclassified to restructuring costs.
