CoreSite Reports Second-Quarter 2017 Financial Results Reflecting
Revenue Growth of 23% Year over Year

DENVER, CO – July 27, 2017 – CoreSite Realty Corporation (NYSE:COR), a premier provider of secure, reliable, high-performance data center and interconnection solutions across the U.S., today announced financial results for the second quarter ended June 30, 2017. 

Quarterly Highlights

“During the second quarter, we again achieved strong financial results, highlighted by year-over-year revenue growth of 23%, adjusted EBITDA growth of 27% and FFO per share growth of 24%,” said Paul Szurek, CoreSite’s Chief Executive Officer. “Our nearly $12 million in annualized GAAP rent signed in new and expansion sales includes a significant expansion with a Fortune 500 customer in the Los Angeles market and several other key deployments. Our leasing activity demonstrates continuing strong demand for larger scale, higher-density, data-intensive deployments seeking campus interconnection to large and diverse carrier-neutral interconnection nodes. We believe these deployments are building blocks for increasing attractiveness to enterprise and network customers.”

Financial Results

CoreSite reported net income attributable to common shares of $15.6 million, or $0.46 per diluted share, for the three months ended June 30, 2017, compared to $12.0 million, or $0.37 per diluted share for the three months ended June 30, 2016, an increase of 24.3% on a per-share basis. On a sequential-quarter basis, net income attributable to common shares decreased 4.2%, reflecting primarily the financings executed in April 2017, which increased CoreSite’s weighted average interest rate to 3.31% from 3.00% in the first quarter, the aforementioned end of lease payments for a prior customer at SV3, and an acceleration of increased seasonal power costs.

CoreSite reported FFO per diluted share and unit of $1.10 for the three months ended June 30, 2017, an increase of 23.6% compared to $0.89 per diluted share and unit for the three months ended June 30, 2016. On a sequential-quarter basis, FFO per diluted share and unit decreased 2.7%, again reflecting the financing transactions executed in April and the acceleration of increased seasonal power costs mentioned above.

Total operating revenues for the three months ended June 30, 2017, were $117.9 million, a 22.7% increase year over year and an increase of 2.6% on a sequential-quarter basis.

Sales Activity

CoreSite executed 119 new and expansion data center leases representing $11.9 million of annualized GAAP rent during the second quarter, comprised of 51,568 NRSF at a weighted-average GAAP rental rate of $208 per NRSF. Second-quarter annualized GAAP rent includes contractual payments related to reserved dedicated expansion space, which is excluded from the GAAP annualized rent per leased NRSF rate.

CoreSite’s second-quarter data center lease commencements totaled 25,712 NRSF at a weighted average GAAP rental rate of $256 per NRSF, which represents $6.6 million of annualized GAAP rent.

CoreSite’s renewal leases signed in the second quarter totaled $12.9 million in annualized GAAP rent, comprised of 83,097 NRSF at a weighted-average GAAP rental rate of $156 per NRSF, reflecting a 2.6% increase in rent on a cash basis and a 6.5% increase on a GAAP basis. The second-quarter rental churn rate was 2.6%, which includes 170 basis points of churn related to CoreSite’s original full-building customer at SV3, as previously disclosed.

This earnings release and accompanying supplemental information may contain 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 some cases, you can identify forward-looking statements by the use of forward-looking terminology such as “believes,” “expects,” “may,” “will,” “should,” “seeks,” “approximately,” “intends,” “plans,” “pro forma,” “estimates” or “anticipates” or the negative of these words and phrases or similar words or phrases that are predictions of or indicate future events or trends and that do not relate solely to historical matters. Forward-looking statements involve known and unknown risks, uncertainties, assumptions and contingencies, many of which are beyond CoreSite’s control that may cause actual results to differ significantly from those expressed in any forward-looking statement. These risks include, without limitation: the geographic concentration of the company’s data centers in certain markets and any adverse developments in local economic conditions or the demand for data center space in these markets; fluctuations in interest rates and increased operating costs; difficulties in identifying properties to acquire and completing acquisitions; significant industry competition; the company’s failure to obtain necessary outside financing; the company’s ability to service existing debt; the company’s failure to qualify or maintain its status as a REIT; financial market fluctuations; changes in real estate and zoning laws and increases in real property tax rates; and other factors affecting the real estate industry generally. All forward-looking statements reflect the company’s good faith beliefs, assumptions and expectations, but they are not guarantees of future performance. Furthermore, 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 most recent annual report on Form 10-K, and other risks described in documents subsequently filed by the company from time to time with the Securities and Exchange Commission.

Funds From Operations “FFO” is a supplemental measure of our performance which should be considered along with, but not as an alternative to, net income and cash provided by operating activities as a measure of operating performance and liquidity. We calculate 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), excluding gains (or losses) from sales of property and undepreciated land and impairment write-downs of depreciable real estate, plus real estate related depreciation and amortization (excluding amortization of deferred financing costs) and after adjustments for unconsolidated partnerships and joint ventures. FFO attributable to common shares and units represents FFO less preferred stock dividends declared during the period.

Our 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.

We offer this measure because we recognize that FFO will be used by investors as a basis to compare our operating performance with that of other REITs. However, because FFO excludes depreciation and amortization and captures neither the changes in the value of our 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 our properties, all of which have real economic effect and could materially impact our financial condition and results from operations, the utility of FFO as a measure of our performance is limited. FFO is a non-GAAP measure and should not be considered a measure of liquidity, an alternative to net income, cash provided by operating activities or any other performance measure determined in accordance with GAAP, nor is it indicative of funds available to fund our cash needs, including our ability to pay dividends or make distributions. In addition, our calculations of FFO are not necessarily comparable to FFO as calculated by other REITs that do not use the same definition or implementation guidelines or interpret the standards differently from us. Investors in our securities should not rely on these measures as a substitute for any GAAP measure, including net income.

EBITDA is defined as earnings before interest, taxes, depreciation and amortization. We calculate adjusted EBITDA by adding our non-cash compensation expense, transaction costs from unsuccessful deals and business combinations and litigation expense as well as adjusting for the impact of impairment charges, gains or losses from sales of property and undepreciated land and gains or losses on early extinguishment of debt. Management uses EBITDA and adjusted EBITDA as indicators of our ability to incur and service debt. In addition, we consider EBITDA and adjusted EBITDA to be appropriate supplemental measures of our performance because they eliminate depreciation and interest, which permits investors to view income from operations without the impact of non-cash depreciation or the cost of debt. However, because EBITDA and adjusted EBITDA are calculated before recurring cash charges including interest expense and taxes, and are not adjusted for capital expenditures or other recurring cash requirements of our business, their utilization as a cash flow measurement is limited.
