CoreSite Reports Fourth-Quarter 2017 Financial Results Reflecting
Revenue Growth of 14.0% Year over Year

DENVER, CO – February 8, 2018 – 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 fourth quarter ended December 31, 2017. 

Quarterly and Subsequent Highlights

“We finished out the year with solid results, highlighted by fourth-quarter revenue, adjusted EBITDA and FFO growth, before the one-time Preferred Stock redemption charge, of 14%, 13%, and 11%, year over year, respectively,” said Paul Szurek, CoreSite’s Chief Executive Officer. “Organic growth was driven primarily by the continued expansion of existing customers across the portfolio and also by new logo growth as we continue to attract valuable deployments to our facilities, driving interactions and interconnections among our customers. When looking at 2017 in its entirety, we executed well on our strategic priorities and took important steps to grow our differentiated scalable and flexible campus strategy in key markets, including Santa Clara, Northern Virginia, Los Angeles, and most recently, Chicago.”

Financial Results

CoreSite reported net income attributable to common shares of $14.9 million, or $0.44 per diluted share, for the three months ended December 31, 2017, compared to $14.9 million, or $0.44 per diluted share for the three months ended December 31, 2016.  Net income per diluted share declined 4.3% on a sequential-quarter basis, due to a one-time non-cash expense related to the original issuance costs associated with CoreSite’s redeemed Preferred Stock.

CoreSite reported FFO per diluted share and unit, excluding the aforementioned one-time non-cash expense related to the original issuance costs associated with CoreSite’s redeemed Preferred Stock, of $1.18 for the three months ended December 31, 2017, an increase of 11.3% compared to $1.06 per diluted share and unit for the three months ended December 31, 2016.

Dividend

On December 7, 2017,  CoreSite announced a dividend of $0.98 per share of common stock and common stock equivalents for the fourth quarter of 2017. The $0.98 per share quarterly dividend represents a $0.08, or 8.9%, increase over the prior quarterly dividend of $0.90 per share that was established in May 2017, and a $0.18, or 22.5%, increase over the dividend rate set in December 2016.

2018 Guidance 

CoreSite is introducing its 2018 guidance of net income attributable to common shares in the range of $2.15 to $2.27 per diluted share.  In addition, the company’s guidance of FFO per diluted share and unit is a range of $4.92 to $5.04, with the difference between net income and FFO being real estate depreciation and amortization. 

CoreSite’s 2018 guidance of FFO per diluted share reflects the company’s adoption of two new accounting standards – revenue recognition and lease accounting, which are cumulatively expected to reduce FFO per diluted share by approximately $0.06 per share.  Absent these accounting changes, CoreSite’s 2018 guidance midpoint would reflect 11.5% year-over-year growth.

This outlook is based on current economic conditions, internal assumptions about CoreSite’s customer base, and the supply and demand dynamics of the markets in which CoreSite operates. The guidance does not include the impact of any future financing, investment or disposition activities, beyond what has already been disclosed.

CoreSite will participate in Citi’s 2018 Global Property CEO Conference on March 5-6, 2018, at The Diplomat Resort & Spa in Hollywood, Florida.

(1) FFO available to shares and units, as adjusted, excludes $4.3 million, or $0.09 per share and unit, of non-cash expense related to the original issuance costs associated with our redeemed Preferred Stock.

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.
