Fourth Quarter 2010 Results

For the quarter ended December 31, 2010, the company reported earnings of $0.10 per share compared to a loss of $0.16 per share for the fourth quarter of 2009. The difference is primarily due to the fourth quarter 2009 loss on the discontinuance of a cash flow hedge of $13.7 million, or $0.20 per share.

Revenues increased 25.3%, or $13.3 million, to $66.0 million for the fourth quarter of 2010 over the fourth quarter of 2009. This revenue increase includes a reduction of $1.8 million, or 2.7%, due to energy cost savings from the company’s continued participation in load management and rate setting programs. These energy savings, while a reduction of revenue, also represent a direct reduction of property operating costs due to the triple net lease structure in place with our tenants and, therefore, have no negative impact to earnings or Funds from Operations (“FFO”).

FFO for the quarter ended December 31, 2010 was $0.33 per share compared to $0.05 per share for the quarter ended December 31, 2009. Excluding the one-time loss on discontinuance of the cash flow hedge noted above, FFO was $0.25 per share for the fourth quarter of 2009. The increase is primarily due to higher operating income due to the lease up of certain operating properties.

Year Ended December 31, 2010 Results

For the year ended December 31, 2010, the company reported earnings of $0.51 per share compared to earnings of $0.04 per share for 2009. Revenues increased 21.1%, or $42.3 million, to $242.5 million for the year ended December 31, 2010 over the corresponding period in 2009. This revenue increase was offset by a reduction of $5.1 million, or 2.1%, due to 2010 energy cost savings from the company’s participation in load management and rate setting programs. FFO for the year ended December 31, 2010 was $1.33 per share compared to $0.88 per share for 2009. FFO for 2009 was negatively impacted by the aforementioned $0.20 per share loss on discontinuance of a cash flow hedge.

Portfolio Update

During the fourth quarter of 2010, the company:

For the twelve months ended December 31, 2010, the company:

Capital Markets Update

In October 2010, the company sold 7.4 million shares of 7.875% Series A perpetual preferred stock at a price of $25 per share, raising net proceeds of approximately $179 million in an underwritten public offering. The company used the proceeds from this offering and a portion of its cash on hand to pay off in full the $196.5 million ACC4 Term Loan on October 25, 2010 that was originally due to mature in October 2011. The company’s earliest debt maturity is the $150 million ACC5 Term Loan in December 2014.

In February 2011, the company amended its $100 million line of credit and lowered its interest rate on this facility by eliminating the LIBOR floor of 1% and instituting a tiered pricing grid based upon leverage that ranges from LIBOR plus 3.25% to LIBOR plus 4.25%. As of today, there are no borrowings under this facility.

2011 Guidance

The company has established an FFO guidance range of $0.36 to $0.39 per share for the first quarter of 2011. The primary differences between the company’s fourth quarter 2010 FFO and the midpoint of the first quarter 2011 FFO guidance is the write-off of unamortized deferred financing costs of $0.03 per share in the fourth quarter of 2010 and $0.02 per share of increased operating income.

The company has established an FFO guidance range of $1.50 to $1.70 per share for the full year 2011. The assumptions underlying this guidance are listed on page 15 of this release. The primary differences between the company’s 2010 FFO and the midpoint of the 2011 FFO guidance are:

DUPONT FABROS TECHNOLOGY, INC.

RECONCILIATIONS OF NET INCOME TO FFO AND AFFO ⁽¹⁾

(in thousands except share and per share data)

The Company 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 expenses. The Company also believes that, as a widely recognized measure of the performance of equity REITs, FFO will be used by investors as a basis to compare the Company’s operating performance with that of other REITs. However, because FFO excludes real estate related depreciation and amortization and captures neither the changes in the value of the Company’s properties that result from use or market conditions nor the level of capital expenditures and leasing commissions necessary to maintain the operating performance of the Company’s properties, all of which have real economic effects and could materially impact the Company’s results from operations, the utility of FFO as a measure of the Company’s performance is limited.

While FFO is a relevant and widely used measure of operating performance of equity REITs, other equity REITs may use different methodologies for calculating FFO and, accordingly, FFO as disclosed by such other REITs may not be comparable to the Company’s FFO. Therefore, the Company believes that in order to facilitate a clear understanding of its historical operating results, FFO should be examined in conjunction with net income as presented in the consolidated statements of operations. FFO should not be considered as an alternative to net income or to cash flow from operating activities (each as computed in accordance with GAAP) or as an indicator of our liquidity, nor is it indicative of funds available to fund the Company’s cash needs, including its ability to pay dividends or make distributions.

The Company also presents FFO with supplemental adjustments to arrive at Adjusted FFO (“AFFO”). AFFO is FFO attributable to common shares and OP units excluding straight-line revenue, non-cash stock based compensation, gain or loss on derivative instruments, acquisition of service agreements, below market lease amortization net of above market lease amortization and early extinguishment of debt costs. AFFO does not represent cash generated from operating activities in accordance with GAAP and therefore should not be considered an alternative to net income as an indicator of the Company’s operating performance or as an alternative to cash flow provided by operations as a measure of liquidity and is not necessarily indicative of funds available to fund the Company’s cash needs including the Company’s ability to pay dividends. In addition, AFFO may not be comparable to similarly titled measurements employed by other companies. The Company’s management uses AFFO in management reports to provide a measure of REIT operating performance that can be compared to other companies using AFFO.
