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; 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 forwardlooking statement speaks only as of the date on which it was 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, 2016 and other periodic reports the Company files with the Securities and Exchange Commission. 2 QTS Q4 Earnings 2017 Contact: IR@qtsdatacenters.com

Redevelopment Costs Summary (in millions, except NRSF data) During the fourth quarter of 2017, the Company did not bring online any space or power. For the year ended December 31, 2017, the Company brought online approximately 13 megawatts of gross power and approximately 58,000 NRSF of raised floor and customer specific capital at its Atlanta-Metro, Chicago, Irving, Fort Worth and Northern Virginia facilities at an aggregate cost of approximately $122 million. Relative to the redevelopment plan disclosed in the prior quarter, and as a result of the capital investments made in new markets during the second half of 2017, the Company has pushed out a portion of development space in Atlanta-Metro, Irving, Chicago and Piscataway that was previously scheduled to come online in the fourth quarter of 2017. The Company now expects this development space to be brought online during 2018 as part of its overall focus on capital efficiency and discipline.

Leasing Statistics 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 Company s rate performance will vary quarter to quarter based on the mix of deals leased C1 - Custom Data Center, C2 - Colocation (Cabinet, Cage and Suite), and C3 - Cloud and Managed Services categories all vary on a rate per square foot basis. The amounts below include renewals when there was a change in square footage rented, and renewals where C3 dedicated server cloud customers had shifts in their MRR related to their use of fully depreciated equipment. The amounts below exclude renewals where square footage remained consistent before and after renewal. (See renewal table on page 16 for such renewals). During the fourth quarter of 2017, the Company entered into 436 new and modified leases aggregating to $18.1 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 $8.7 million in incremental annualized rent for the quarter ended December 31, 2017. Subsequent to December 31, 2017, the Company signed a lease to refill the previously vacated space in one of its leased facilities in Northern Virginia. Had the lease closed in the fourth quarter of 2017, as previously expected, fourth quarter 2017 net leasing would have exceeded $14 million. Blended pricing on new and modified leases signed during the fourth quarter was higher than the prior four quarter average, which was driven by a higher proportion of C2/C3 deals signed in the fourth quarter of 2017. Pricing of C2/C3 new and modified leases signed during the fourth quarter decreased compared to the prior four quarter average due primarily to several larger footprint C2 deals which tend to have a lower price per square foot compared to C3 deals. Annualized Rent of New and Modified Leases represents total MRR associated with all new and modified leases for the respective periods for purposes of computing annualized rent rates per square foot during the period. Incremental Annualized Rent, Net of Downgrades reflects net incremental MRR signed during the period for purposes of tracking incremental revenue contribution.

(2) Annualized revenue represents the booked-not-billed MRR multiplied by 12, demonstrating how much recognized MRR might have been recognized if the booked-notbilled leases commencing in the period were in place for an entire year. 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 December 31, 2017 to be approximately $27 million. This estimate generally includes C1 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. 16 QTS Q4 Earnings 2017 Contact: IR@qtsdatacenters.com

Leasing Statistics Renewed Leases and 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 deals leased C1 Custom Data Center, C2 Colocation, and C3 Cloud and Managed Services categories all vary on a rate per square foot basis. Consistent with the Company s 3C strategy and business model, the renewal rates below reflect total MRR per square foot including all subscribed services. 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 renewals signed in the fourth quarter of 2017 was 1.2% 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. Rental Churn (which the Company defines as MRR lost in the period to a customer intending to fully exit the QTS platform in the near term compared to total MRR at the beginning of the period) was 2.8% for the fourth quarter of 2017, of which 1.2% related to a C3 customer who terminated due to liquidation. Rental Churn was 8.4% for the year ended December 31, 2017, a significant portion of which was the result of a single customer termination in the first quarter of 2017 at one of the Company s leased facilities in Northern Virginia, for which space was subsequently re-leased by the Company in the first quarter of 2018. Excluding this customer termination as well as the C3 customer churn due to liquidation in the fourth quarter of 2017, rental churn for the year ended December 31, 2017 would have been 4.7%.

C1 Custom Data Center, C2 Colocation, and C3 Cloud and Managed Services categories all vary on a rate per square foot basis. During the fourth quarter of 2017, the Company commenced customer leases (which includes both new customers and existing customers that renewed their lease terms) representing approximately $26.9 million of annualized rent at $718 per square foot. This compares to customer leases representing an aggregate trailing four quarter average of approximately $31.3 million of annualized rent at $549 per square foot. Average pricing on commenced leases during the fourth quarter of 2017 increased compared to the prior four quarter average primarily due to a larger mix of C2/C3 commencements which tend to have a higher rate per square foot in comparison to C1 deals.

MRR does not include the impact from booked-not-billed leases as of a particular date, unless otherwise specifically noted. This amount reflects the annualized cash rental payments. It does not reflect the accounting associated with any free rent, rent abatements or future scheduled rent increases and also excludes operating expense and power reimbursements.
