Leasing activity was healthy across the portfolio, led by the Silicon Valley, New York, Chicago, and Los Angeles markets. We believe our activities closing out 2014 point toward another year of solid growth in 2015, as we set the stage for anticipated new developments within existing facilities across multiple markets in our portfolio, including at BO1, CH1, DE1, NY2, and VA2, and we continue to evaluate developing additional capacity at LA2 and on our Coronado Campus in Santa Clara.”

Financial Results

CoreSite reported FFO attributable to shares and units of $25.9 million for the three months ended September 30, 2014, an 18.4% increase year over year and a decrease of 3.1% on a sequential basis, owing in part to the previously-reported $3.7 million non-recurring benefit recorded in the second quarter related to adjustments to accruals for real estate taxes. On a per diluted share and unit basis, FFO increased 17.0% to $0.55 for the three months ended September 30, 2014, as compared to $0.47 per diluted share and unit for the three months ended September 30, 2013.

Total operating revenues for the three months ended September 30, 2014, were $70.5 million, a 16.3% increase year over year. Data center revenues for the three months ended September 30, 2014, were $68.5 million, a 16.7% increase year over year. CoreSite reported net income attributable to common shares of $3.1 million, or $0.14 per diluted share.

Sales Activity

CoreSite executed 118 new and expansion data center leases representing $7.6 million of annualized GAAP rent during the third quarter, comprised of 54,123 NRSF at a weighted-average GAAP rate of $141 per NRSF.

CoreSite’s renewal leases signed in the third quarter totaled $12.1 million in annualized GAAP rent, comprised of 55,262 NRSF at a weighted average GAAP rate of $219 per NRSF, reflecting a 3.0% increase in rent on a cash basis and a 10.6% increase on a GAAP basis. The third-quarter rental churn rate was 1.2%.

CoreSite’s third-quarter data center lease commencements totaled 45,014 NRSF at a weighted average GAAP rental rate of $135 per NRSF, which represents $6.1 million of GAAP annualized rent.

Development Activity

CoreSite had 50,000 NRSF of data center space under construction at VA2 in Reston, Virginia, at the end of the third quarter. As of September 30, 2014, CoreSite had incurred $69.7 million of the estimated $74.9 million required to complete this project.

During the third quarter, CoreSite also began construction on 15,149 NRSF of data center space at BO1 in Boston, which the company expects to complete in the second quarter of 2015 at an estimated cost of $9.5 million.

Balance Sheet and Liquidity

As of September 30, 2014, CoreSite had $305.3 million of total long-term debt, correlating to 2.3 times third-quarter annualized adjusted EBITDA and $420.3 million of long-term debt and preferred stock, correlating to 3.2 times third-quarter annualized adjusted EBITDA.

At quarter end, CoreSite had $9.3 million of cash available on its balance sheet and $192.4 million of capacity available under its credit facility.

Dividend

On August 29, 2014, CoreSite announced a dividend of $0.35 per share of common stock and common stock equivalents for the third quarter of 2014. The dividend was paid on October 15, 2014, to shareholders of record on September 30, 2014.

CoreSite also announced on August 29, 2014, a dividend of $0.4531 per share of Series A preferred stock for the period July 15, 2014, to October 14, 2014. The preferred dividend was paid on October 15, 2014, to shareholders of record on September 30, 2014.

2014 Guidance

Excluding a previously-disclosed one-time charge of $0.02 per share and unit in the first quarter and a one-time net benefit recorded in the second quarter in the amount of $0.06 per share, CoreSite is increasing its guidance of FFO per diluted share and unit to a range of $2.12 to $2.16 from the previous range of $2.07 to $2.15. Including the above-referenced one-time items, CoreSite is increasing its 2014 guidance of FFO per diluted share and unit to a range of $2.16 to $2.20.

In addition, CoreSite is revising its 2014 guidance for net income attributable to common shares to a range of $0.59 to $0.63 per diluted share from the previous range of $0.61 to $0.69 per diluted share. The difference between FFO and net income is attributable to real estate depreciation and amortization.

This outlook is predicated 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.

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 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 and litigation expense and impairment charges to EBITDA as well as adjusting for the impact of 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.
