BIOMED REALTY TRUST REPORTS

SECOND QUARTER 2011 FINANCIAL RESULTS

Signed 602,500 SF of Leasing and Continued Strong Same Property Cash NOI Growth – up 6.8% Year-Over-Year

SAN DIEGO, Calif. - August 3, 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 second quarter ended June 30, 2011.

Second Quarter 2011 Highlights

Subsequent to quarter end, the company:

Alan D. Gold, Chairman and Chief Executive Officer of BioMed, commented, “The best-in-class BioMed team produced yet another outstanding, record-breaking quarter with total revenues and rental revenues. We increased gross leasing volume for the fifth consecutive quarter to over 602,000 square feet. This puts us at 1.4 million square feet, 16% above our five-quarter leasing goal of 1.2 million square feet with six months still remaining. In addition, we continued to pursue our highly disciplined investment strategy in the second quarter, highlighted by our new Ardsley Park campus where we were able to add a very desirable property to our New York portfolio and concurrently sign a long-term lease with a top-tier tenant in Acorda Therapeutics, which we expect to result in a superior risk-adjusted rate of return. This high level of operating success continues to drive exceptional top-line and bottom-line results and provides further evidence of the power of building a business on the foundation of providing high-quality, well-located real estate to the life science industry.”

Second Quarter 2011 Financial Results

Total revenues for the second quarter were $106.8 million, compared to $92.9 million for the same period in 2010, an increase of 14.9%, and the highest in the company’s history for the third consecutive quarter. Rental revenues for the second quarter were $81.4 million, compared to $72.4 million for the same period in 2010, an increase of 12.5%, also the highest in the company’s history for the third consecutive quarter.

The current operating portfolio’s leased percentage increased to 90.5% as of June 30, 2011. Same property net operating income on a cash basis increased 6.8% 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 second quarter was $3.6 million, or $0.03 per diluted share, compared to $4.2 million, or $0.04 per diluted share, for the same period in 2010. FFO for the quarter was $42.1 million, or $0.29 per diluted share, compared to $33.1 million, or $0.27 per diluted share, for the same period in 2010. AFFO for the quarter was $38.3 million, or $0.27 per diluted share, compared to $30.0 million, or $0.24 per diluted share, for the same period in 2010.

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.

Our FFO available to common shares and partnership and LTIP units and a reconciliation to net income for the three and six months ended June 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 six months ended June 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.
