BIOMED REALTY TRUST REPORTS SECOND QUARTER 2012 FINANCIAL RESULTS

Core FFO per share climbs 10.3% year-over-year to $0.32 per diluted share

SAN DIEGO, Calif. – August 1, 2012 – 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, 2012.

Second Quarter 2012 Highlights

Alan D. Gold, BioMed Realty’s Chairman and Chief Executive Officer, commented, “The second quarter results were very strong as we continued to capitalize on our core competency – our expertise in life science real estate – to create value for shareholders. First and foremost, our sustained leasing success has produced significant year-over-year top line growth, with record total and rental revenues, and bottom line results, with per share CFFO and AFFO growth of 10.3% and 22.2%, respectively. The continued and consistently superior execution of our capital strategy enabled us to expand BioMed Realty’s best-in-class property portfolio to include Granta Park in the distinguished Cambridge, UK life science cluster and, closer to home, our development project with Shire Regenerative Medicine in San Diego. Our sustained, superior operating and financial results are the byproduct of the disciplined execution of our great business model by the top team of professions in the industry, our ability to leverage our robust operating platform, and the tremendous flexibility in our capital position.”

Portfolio Update

During the quarter ended June 30, 2012, the company executed 23 leasing transactions representing approximately 350,800 square feet, comprised of:

Subsequent to the end of the second quarter, the company signed a lease extension with a subsidiary of Vertex Pharmaceuticals Incorporated for approximately 81,200 square feet at the company’s Torreyana Road property located in the heart of the Torrey Pines submarket of San Diego, California.

During the quarter ended June 30, 2012, the company purchased Granta Park in Cambridge, United Kingdom for approximately 126.8 million pounds sterling, or approximately $196.0 million, excluding transaction costs. The campus comprises eleven laboratory and office buildings aggregating approximately 472,200 square feet of space, which are fully leased to a diversified roster of eleven tenants, as well as approximately 138,400 square feet of

development and expansion rights. With this new investment, the company has expanded current tenant relationships with MedImmune (and parent company AstraZeneca) and Pfizer, as well as established new tenant relationships with Gilead Sciences, Pharmaceutical Product Development, UCB and Vernalis.

Also during the second quarter of 2012, the company acquired Summers Ridge, comprising two parcels of land and approximately 28 adjacent acres in San Diego, California for a purchase price of approximately $47 million. Concurrently, the company entered into a long-term ground lease for both parcels with Shire Regenerative Medicine (formerly Advanced BioHealing, Inc.), a subsidiary of Shire plc, which plans to construct office, laboratory, warehouse and manufacturing facilities totaling in excess of 150,000 square feet on the site, commencing by early next year. The site can accommodate future expansion of up to a total of 800,000 square feet.

Subsequent to quarter end, the company completed the acquisition of the 9900/9901 Belward Drive property in Rockville, Maryland for approximately $26.2 million. The two building property comprises approximately 106,500 square feet of laboratory and office space which is approximately 92% leased. The company assumed loans secured by mortgages on the two buildings with an aggregate principal balance of approximately $24.1 million, a weighted-average interest rate of approximately 5.64% and maturity dates in July 2017.

At June 30, 2012, the company’s total portfolio comprised approximately 13.0 million rentable square feet with an additional 4.0 million square feet of development potential.

“Our recognized depth of understanding with respect to life science real estate, in combination with our efficiently managed liquidity and capital position, facilitated our successful transactions this quarter,” noted Kent Griffin, the company’s President and Chief Operating Officer. “Granta Park, in addition to enjoying long-term leases with an A-list tenant roster, provides us with immediate critical mass in a new market, and additional capacity to provide for future expansion and thereby meet growing tenant needs. Our San Diego land investment, with a concurrent ground lease to a credit tenant, is yet another example of our creativity and tenacity – affording us another strong success, with a very attractive risk-adjusted return profile. Our most recent investments really highlight the strength of our operating team and their ability to translate our skills and expertise as an organization into tangible value creation opportunities for our shareholders.”

Second Quarter 2012 Financial Results

Total revenues for the second quarter were $124.8 million, compared to $106.4 million for the same period in 2011, an increase of 17.3% and the highest in the company’s history for the second consecutive quarter.

Same property net operating income on a cash basis increased for the period by 6.4% and the same property leased percentage increased by 460 basis points for the quarter compared to the same period in 2011, primarily as a result of sustained leasing success and contractual rent escalations.

The company reported a net loss available to common stockholders for the second quarter of $8.7 million, or $0.06 per diluted share, which includes $12.2 million of acquisition-related expenses, or $0.08 per diluted share.

Core FFO was $52.9 million for the quarter, or $0.32 per diluted share, which grew 10.3% compared to $0.29 per diluted share for the same period in 2011. AFFO was $55.6 million for the quarter, or $0.33 per diluted share, which increased 22.2% compared to $0.27 per diluted share for the same period in 2011. These core FFO and AFFO results exclude acquisition-related expenses of $0.08 per diluted share and $0.00 per diluted share for the three months ended June 30, 2012 and 2011, respectively.

FFO, CFFO 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, CFFO and AFFO and definitions of terms are included at the end of this release.

Our FFO and CFFO available to common shares and partnership and LTIP units and a reconciliation to net income for the three and six months ended June 30, 2012 and 2011 was as follows:

Our AFFO available to common shares and partnership and LTIP units and a reconciliation of CFFO to AFFO for the three and six months ended June 30, 2012 and 2011 was as follows:

We present funds from operations, or FFO, core funds from operations, or CFFO, 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, CFFO 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. As defined by NAREIT, FFO represents net income (computed in accordance with GAAP), excluding gains (or losses) from sales of property, impairment charges on depreciable real estate, real estate related depreciation and amortization (excluding amortization of loan origination costs) and after adjustments for unconsolidated partnerships and joint ventures.

We calculate core FFO by adding acquisition-related expenses to FFO. We calculate AFFO by adding to CFFO: (a) non-cash revenues and expenses, (b) recurring capital expenditures and second generation tenant improvements, and (c) leasing commissions.

Our computation of FFO, CFFO and AFFO may differ from the methodology for calculating FFO, CFFO and AFFO utilized by other equity REITs and, accordingly, may not be comparable to such other REITs. Further, FFO, CFFO 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, CFFO 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, CFFO and AFFO should be considered only as supplements to net income computed in accordance with GAAP as measures of our operations.
