BIOMED REALTY TRUST REPORTS THIRD QUARTER 2011 FINANCIAL RESULTS

Total and Rental Revenues Set Record for Fourth Consecutive Quarter; AFFO Per Share Up 21% Year-Over-Year

SAN DIEGO, Calif. - November 1, 2011 - BioMed Realty Trust, Inc. (NYSE: BMR), a real estate investment trust focused on Providing Real Estate to the Life Science Industry^®, today announced financial results for the third quarter ended September 30, 2011.

Third Quarter 2011 Highlights

Subsequent to quarter end, the company acquired the Wateridge Summit property in San Diego, California for approximately $46.5 million. The property is 100% leased comprising approximately 106,500 rentable square feet.

“Consistent with the past several quarters, we continued to deliver strong financial results driven by broad-based leasing success, tactical new investments and prudent and proactive management of our balance sheet,” said Alan D. Gold, BioMed’s Chairman and Chief Executive Officer. “Gross leasing of 327,000 square feet lifted us to 143% of our five-quarter leasing goal of 1.2 million square feet with one quarter still remaining. Given seller expectations, we continue to be selective in our acquisitions, focusing on high quality assets, such as Wateridge Summit, that enhance our presence in our key markets. Our success in executing our investment strategy continues to fuel near-term revenue and cash flow growth, while also providing for attractive future internal growth opportunities with significant development and redevelopment potential. These exceptional financial results are a direct byproduct of the disciplined execution of our proven business model – investing in high-quality, state-of-the-art research facilities and creating optimal environments for our tenants to succeed in bringing technologies and treatments to patients around the world.”

Third Quarter 2011 Financial Results

Total revenues for the third quarter were $115.0 million, compared to $95.7 million for the same period in 2010, an increase of 20.1%. Rental revenues for the third quarter were $83.8 million, compared to $73.0 million for the same period in 2010, an increase of 14.9%. Total and rental revenues for the third quarter were the highest in the company’s history for the fourth consecutive quarter.

Same property net operating income on a cash basis increased 5.7% for the quarter compared to the same period in 2010, primarily driven by sustained leasing success, commencement of cash rents, and contractual rent escalations.

Net income available to common stockholders for the third quarter was $4.8 million, or $0.03 per diluted share, compared to $4.8 million, or $0.04 per diluted share, for the same period in 2010. FFO for the quarter was $43.8 million, or $0.30 per diluted share, compared to $35.2 million, or $0.28 per diluted share, for the same period in 2010. AFFO for the quarter was $42.5 million, or $0.29 per diluted share, compared to $30.3 million, or $0.24 per diluted share, for the same period in 2010.

FFO for the third quarter included a net loss of approximately $500,000 associated with a lease at the Monte Villa property in Bothell, Washington terminated in the third quarter. This loss was comprised of $4.1 million included in other income, bad debt expense of approximately $1.0 million included in rental operations expense, and an unrealized loss on marketable securities held in the tenant of $3.6 million included in other expense.

FFO and AFFO are supplemental non-GAAP financial measures used in the real estate industry to measure and compare the operating performance of real estate companies. A complete reconciliation containing adjustments from GAAP net income available to common stockholders to FFO and AFFO and definitions of terms are included at the end of this release.

Portfolio Update

During the quarter ended September 30, 2011, the company executed 19 leasing transactions representing approximately 327,000 square feet. As a result, the current operating portfolio weighted average leased percentage was approximately 90.8% at quarter end.

During the quarter ended September 30, 2011, the company sold its Lucent Drive property, consisting of a single building comprising 21,500 square feet in Lebanon, New Hampshire, for approximately $5.9 million.

For accounting purposes, there was no gain or loss on the transaction and the note is classified in other assets.

Subsequent to quarter end, the company acquired the Wateridge Summit property in San Diego, California for approximately $46.5 million. The property is 100% leased comprising approximately 106,500 rentable square feet.

At September 30, 2011, the company’s total portfolio comprised approximately 12.3 million rentable square feet, with an additional 3.7 million square feet of development potential, including the following:

Financing Activity

In July 2011, the company entered into a new $750 million unsecured revolving credit facility, replacing the previous unsecured revolving credit facility which had a maturity date of August 1, 2011. The new facility matures on July 13, 2015, and can be extended for one year at the company’s option. In addition, the terms of the new agreement permit BioMed to increase the amount of the facility to $1.25 billion after satisfying certain conditions. Interest paid on drawings under the new facility is set at LIBOR plus 155 basis points, subject to adjustments based on changes to BioMed’s credit ratings.

In July 2011, the company voluntarily prepaid a $17.5 million previously outstanding mortgage on the company’s 9865 Towne Centre Drive property in San Diego, California. The mortgage had an interest rate of 7.95% and the prepayment resulted in a loss on early extinguishment of debt that reduced FFO by $521,000. In addition, the company extended the maturity date to August 2013 for the construction loan secured by the 650 East Kendall Street property, which is owned through the company’s PREI^® joint venture.

In August 2011, the company repurchased 1,280,000 shares of the company’s Series A preferred stock, $25.00 liquidation preference per share, for approximately $31.1 million, or $24.30 per share, net of accrued dividends.

Subsequent to the end of the quarter, the company repurchased and redeemed the remaining $19.8 million principal amount outstanding of its 4.50% exchangeable senior notes due 2026, and prepaid a $13.0 million outstanding mortgage on the company’s Sorrento West property in San Diego, California, which had an interest rate of 7.42%.

Quarterly and Annual Distributions

BioMed Realty Trust’s board of directors previously declared a third quarter 2011 dividend of $0.20 per share of common stock, and a dividend of $0.46094 per share of the company’s 7.375% Series A Cumulative Redeemable Preferred Stock for the period from July 16, 2011 through October 15, 2011.

Earnings Guidance

The company further narrowed its 2011 projected guidance for FFO per diluted share from the range provided in its earnings release on August 3, 2011 to FFO per diluted share of $1.17 - $1.19. Projected FFO per diluted share is based upon estimated, weighted-average diluted common shares outstanding of approximately 144 million.

The company’s initial 2012 guidance for net income per diluted share and FFO per diluted share is set forth and reconciled below. Projected FFO per diluted share is based upon estimated, weighted-average diluted common shares outstanding of approximately 145 million.

At the midpoint, the company’s 2012 FFO guidance represents an 8.5% increase over the midpoint of current 2011 annual guidance.

The 2012 guidance includes the following assumptions:

Financing Activity

Other

The company continues to target new investment opportunities, including acquisitions and new development projects, however the company’s 2012 FFO estimates do not reflect the impact of any future new investments (acquisitions or development) as the FFO impact of such investments may vary significantly based on the nature of these investments, timing and other factors.

Our FFO available to common shares and partnership and LTIP units and a reconciliation to net income for the three and nine months ended September 30, 2011 and 2010 was as follows:

Our AFFO available to common shares and partnership and LTIP units and a reconciliation of FFO to AFFO for the three and nine months ended September 30, 2011 and 2010 was as follows:

We present funds from operations, or FFO, and adjusted funds from operations, or AFFO, available to common shares and partnership and LTIP units because we consider them important supplemental measures of our operating performance and believe they are frequently used by securities analysts, investors and other interested parties in the evaluation of REITs, many of which present FFO and AFFO when reporting their results.

FFO is intended to exclude GAAP historical cost depreciation and amortization of real estate and related assets, which assumes that the value of real estate assets diminishes ratably over time. Historically, however, real estate values have risen or fallen with market conditions. Because FFO excludes depreciation and amortization unique to real estate, gains and losses from property dispositions and extraordinary items, it provides a performance measure that, when compared year over year, reflects the impact to operations from trends in occupancy rates, rental rates, operating costs, development activities and interest costs, providing perspective not immediately apparent from net income. We compute FFO in accordance with standards established by the Board of Governors of the National Association of Real Estate Investment Trusts, or NAREIT, in its March 1995 White Paper (as amended in November 1999 and April 2002). As defined by NAREIT, FFO represents net income (computed in accordance with GAAP), excluding gains (or losses) from sales of property, plus real estate related depreciation and amortization (excluding amortization of loan origination costs) and after adjustments for unconsolidated partnerships and joint ventures.

We calculate AFFO by adding to FFO: (a) amounts received pursuant to master lease agreements on certain properties, which are not included in rental income for GAAP purposes, (b) non-cash revenues and expenses, (c) recurring capital expenditures and tenant improvements, and (d) leasing commissions.

Our computation of FFO and AFFO may differ from the methodology for calculating FFO and AFFO utilized by other equity REITs and, accordingly, may not be comparable to such other REITs. Further, FFO and AFFO do not represent cash flow available for management’s discretionary use because of needed capital replacement or expansion, debt service obligations, or other commitments and uncertainties. FFO and AFFO should not be considered as an alternative to net income (loss) (computed in accordance with GAAP) as an indicator of our financial performance or to cash flow from operating activities (computed in accordance with GAAP) as an indicator of our liquidity, nor is it indicative of funds available to fund our cash needs, including our ability to pay dividends or make distributions. FFO and AFFO should be considered only as supplements to net income computed in accordance with GAAP as measures of our operations.
