QTS REPORTS FOURTH QUARTER 2013 OPERATING RESULTS

OVERLAND PARK, Kan. – February 19, 2014 – QTS Realty Trust, Inc. (the “Company” or the “Successor”) (NYSE: QTS) today announced operating results for the fourth quarter and year ended December 31, 2013. The Company completed its initial public offering on October 15, 2013, pursuant to which the Company became the general partner of QualityTech, LP (the “Predecessor”). Unless otherwise noted, the following data includes financial data on a combined basis for both the Predecessor and the Successor together with their consolidated subsidiaries, which are referred to collectively as “QTS.”

Fourth Quarter Highlights

• Reported Operating FFO of $16.4 million in the fourth quarter of 2013, an increase of 140% compared to the fourth quarter of 2012. Operating FFO for the fourth quarter of 2013 on a fully diluted per share basis was $0.47 per share.

• Reported Adjusted EBITDA of $21.2 million in the fourth quarter of 2013, an increase of 45% compared to the fourth quarter of 2012.

• Total revenues recognized in the fourth quarter 2013 increased by 24% compared to the fourth quarter 2012. Monthly Recurring Revenue (“MRR”) as of December 31, 2013 increased by 19% to $14.1 million compared to MRR as of December 31, 2012.

• During the fourth quarter of 2013 we executed new and modified leases aggregating to a net increase of $9.3 million in incremental annualized rent, net of downgrades, the third highest level in the history of the Company.

• Reported NOI of $30.4 million in the fourth quarter of 2013, an increase of 23% compared to the fourth quarter of 2012.

* Fully diluted per share data is calculated on a pro rata basis accounting for the number of operating partnership units outstanding for the period from October 1, 2013 through October 14, 2013 and the total number of public shares and remaining operating partnership units outstanding from October 15, 2013 through December 31, 2013.

Chad Williams, QTS’ Chairman and Chief Executive Officer, commented, “We are pleased to report solid growth in our operating portfolio and significant momentum heading into 2014 with some of the highest incremental rent leasing levels in the Company’s history. We continue to see significant ongoing activity in each of our 3Cs product offerings (C1 – Custom Data Center, C2 – Colocation, and C3 – Cloud and Managed Services) across our national footprint, supported by what we believe to be industry leading security and compliance expertise, powered by our people. We are continuing to expand our facilities in the Atlanta and Richmond markets and, in the fourth quarter of 2013, commenced the redevelopment of our Dallas facility, a portion of which is scheduled to become operational in the third quarter of 2014.”

Financial results

Net income recognized in the fourth quarter of 2013 was $4.4 million compared to a net loss recognized in the fourth quarter of 2012 of $1.6 million. QTS generated Operating FFO of $16.4 million in the fourth quarter of 2013, which is an increase of approximately 140% compared to $6.9 million for the fourth quarter of 2012. Additionally, QTS generated $21.2 million of Adjusted EBITDA in the fourth quarter of 2013, an increase of approximately 45% compared to $14.7 million for the fourth quarter of 2012. MRR as of December 31, 2013 was $14.1 million, an increase of approximately 19% compared to MRR as of December 31, 2012 of $11.9 million, with total revenues increasing by approximately 24% to $47.4 million for the fourth quarter 2013 compared to $38.2 million for the fourth quarter 2012.

Leasing Activity

During the fourth quarter of 2013, QTS entered into customer leases representing approximately $0.8 million of incremental MRR, net of downgrades, representing approximately $9.3 million of incremental annualized rent, at a weighted average rental rate of $351 per square foot. Incremental MRR, net of downgrades, for the fourth quarter of 2013 was in line with the trailing four quarter average of $0.8 million of MRR, and in line with the trailing four quarter average rate per square foot.

During the fourth quarter of 2013, QTS renewed leases with a total annualized rent of $3.5 million at an average rent per square foot of $922, which was 1.1% lower than the annualized rent prior to their respective renewals, and reflects the impact of a C2 customer which changed its product mix, resulting in a lower rate per square foot. This renewal represents 1 of our 50 renewed leases in the fourth quarter and the renewal rates in the fourth quarter of 2013 would have increased 3.3% without the impact of this renewal. The actual change in fourth quarter renewal rates compares to a prior four quarter average increase of 1.6%, which also reflects the impact of 3 significant C2/C3 renewals signed in the first 2 quarters of 2013. These leases were extended at lower total effective rates as a function of services changes associated with the customer deployments. Overall renewal rate increases in the preceding four quarters would have been 4.1% without the impact of these first half 2013 lease renewals. We define renewals as leases which the customer retains the same amount of space before and after renewal, which facilitates rate comparability. Rental churn (which is the MRR impact from a customer completely departing our platform in a given period compared to the total MRR at the beginning of the period) for the fourth quarter of 2013 was 2.3% and was 5.7% for the twelve months ended 2013.

During the fourth quarter of 2013, QTS commenced customer leases (which includes new customers and also existing customers that renewed their lease term) representing approximately $2.3 million of MRR (representing approximately $27.7 million of annualized rent) at $280 per square foot. This compares to customer leases representing an aggregate trailing four quarter average of approximately $1.3 million of MRR (representing approximately $16.1 million of annualized rent) at $436 per square foot. The difference in these commencements on a per square foot basis is largely due to the timing and magnitude of C1 lease commencements relative to C2/C3 lease commencements. See more detailed analysis in the Company’s supplemental information.

As of December 31, 2013, our booked-not-billed MRR balance (which represents customer leases that have been executed, but for which lease payments have not commenced as of December 31, 2013) was approximately $2.3 million, or $28.2 million of annualized rent. Of this booked-not-billed balance, approximately $0.4 million of MRR was attributable to new customers and approximately $1.9 million of MRR was attributable to existing customers. The booked-not-billed balance is expected to contribute $9.5 million to revenue in 2014 (representing $13.5 million in annualized revenues), $3.6 million in 2015 (representing $8.4 million in annualized revenues), and $6.3 million in annualized revenues thereafter.

Development and Redevelopment Activity

During the fourth quarter of 2013, QTS had a net reduction of 51,000 of net rentable square feet (“NRSF”). QTS obtained approximately 66,000 NRSF relinquished by a C1 tenant in the Atlanta-Metro facility. The majority of this space was redeveloped to accommodate a large C1 tenant and the remaining portion is being redeveloped to accommodate C2 tenants. The space redeveloped for the C1 customer came online in January 2014 and the space which is being redeveloped to accommodate C2 customers is expected to be completed in the second quarter of 2014. During the fourth quarter of 2013, QTS placed 15,000 NRSF into service in the Atlanta-Suwanee facility and placed capital of $12 million into service on its platform. In addition, during the fourth quarter of 2013 we continued redevelopment of our Dallas, Richmond, Atlanta – Suwanee, and Sacramento facilities.

Balance Sheet and Liquidity

As of December 31, 2013, QTS’ total debt balance was $347.9 million (or 4.1x fourth quarter annualized Adjusted EBITDA) and its liquidity was nearly $330 million, consisting of nearly $325 million of available capacity on its credit facilities and approximately $5 million of cash available on its balance sheet. In February 2014, the Company expanded the capacity of its unsecured credit facility by $50 million, increasing the total revolving credit facility capacity to $400 million, to provide additional liquidity.

2014 Guidance

Reconciliations of Net Income (Loss) to FFO, Operating FFO & Adjusted Operating FFO

(in thousands)

The Company calculates FFO in accordance with the standards established by the National Association of Real Estate Investment Trusts, or 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 generally calculates Operating FFO as FFO excluding certain non-recurring and primarily non-cash charges and gains and losses that management believes are not indicative of the results of our operating real estate portfolio. The Company believes that Operating FFO provides investors with another financial measure that may facilitate comparisons of operating performance and liquidity between periods and, to the extent other REITs calculate Operating FFO on a comparable basis, between the Company and these other REITs. 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, non- real estate depreciation, straight-line rent adjustments, and non-cash compensation.

A reconciliation of net income (loss) to FFO, Operating FFO and Adjusted Operating FFO is presented below:

Reconciliations of Net Income (Loss) to EBITDA and Adjusted EBITDA

(in thousands)

The Company calculates EBITDA as net income (loss) excluding interest expense and interest income, provision for income taxes (including income taxes applicable to sale of assets) and depreciation and amortization. The Company believes that EBITDA is another metric that is often utilized to evaluate and compare the Company’s ongoing operating results and also, in part, to assess the value of the Company’s operating portfolio. In addition to EBITDA, the Company calculates an adjusted measure of EBITDA, which the Company refers to as Adjusted EBITDA, as EBITDA excluding write off of unamortized deferred financing costs, gain on extinguishment of debt, transaction costs, equity-based compensation expense, restructuring charge, gain on legal settlement and gain on sale of real estate. The Company believes that Adjusted EBITDA provides investors with another financial measure that can facilitate comparisons of operating performance between periods and between REITs.

Reconciliations of Net Income (Loss) to Net Operating Income (NOI)

(in thousands)

The Company calculates net operating income, or NOI, as net income (loss), excluding: interest expense, interest income, depreciation and amortization, write off of unamortized deferred financing costs, gain on extinguishment of debt, transaction costs, gain on legal settlement, gain on sale of real estate, restructuring charge and general and administrative expenses. The Company believes that 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. A reconciliation of net income (loss) to NOI is presented below:

Reconciliations of Total Revenues to Recognized MRR in the period and MRR at period-end

(in thousands)

The Company calculates MRR as monthly contractual revenue under signed leases as of a particular date, which includes revenue from our C1, C2 and C3 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 (which represent customer leases that have been executed but for which lease payments have not commenced) as of a particular date, unless otherwise specifically noted. The Company calculates recognized MRR as the recurring revenue recognized during a given period, which includes revenue from our C1, C2 and C3 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 and recognized MRR as supplemental performance measures because they provide useful measures of increases in contractual revenue from customer leases. A reconciliation of total revenues to recognized MRR in the period and MRR at period-end is presented below:
