SAN DIEGO, Calif. – February 5, 2013 – BioMed Realty Trust, Inc. (NYSE: BMR), a real estate investment trust (REIT) that delivers optimal real estate solutions for the life science industry, today announced financial results for the fourth quarter and full-year ended December 31, 2012.

Fourth Quarter 2012 Highlights

Alan D. Gold, Chairman and Chief Executive Officer of BioMed Realty, commented, “We are very pleased to report another quarter and year of strong execution of our proven business model. In 2012, we continued to reap the benefits of strong life science industry trends. Leveraging this strength with the location and quality of our properties combined with the skill of our operating team has allowed us to make significant market share gains. In fact, we’ve increased our leased percentage by 1,000 basis points over the last nine quarters – bringing our total operating portfolio to over 92% leased. The cumulative effect of this sustained success helped us deliver a 20% increase in FFO per share in the fourth quarter of 2012.”

2012 Highlights

During the full year 2012, the company:

According to Kent Griffin, President and Chief Operating Officer of BioMed Realty, “Our 2012 results were truly extraordinary and a testimony to our commitment to creating value from the ground up. In addition to the 1.8

million square feet of gross leasing, we identified and delivered $436 million of attractive new investments by leveraging our strong platform, industry expertise and valuable relationships. Individually and collectively, our 2012 investments allow us to capitalize on our core competencies – our expertise in life science real estate combined with a sound, sustained capital strategy – for the benefit of our stockholders. We are very excited about 2013 and the opportunities in front of us, as the result of the success and momentum delivered throughout all facets of our business in 2012.”

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.

Portfolio Update

During the quarter ended December 31, 2012, the company executed 30 leasing transactions representing approximately 624,900 square feet, comprised of 13 new leases totaling approximately 256,600 square feet and 17 lease renewals totaling approximately 368,300 square feet. Leasing activity for the quarter included a lease expansion and extension with Ironwood Pharmaceuticals, Inc. for 93,000 square feet at the company’s 301 Binney Street property in Cambridge, Massachusetts, bringing Ironwood’s total occupancy at the property to approximately 303,300 square feet, and a lease expansion with Regeneron Pharmaceuticals, Inc. for an additional approximately 80,500 square feet at The Landmark at Eastview campus in Tarrytown, New York.

During 2012, the company executed a total of 97 leasing transactions representing approximately 1.8 million square feet, including 61 new leases totaling approximately 1.1 million square feet and 36 leases amended to extend their terms totaling approximately 703,200 square feet. Including leasing activity in the fourth quarter of 2011, the company executed approximately 2.1 million square feet of gross leasing transactions, representing approximately 172% of its original five-quarter goal of 1.2 million square feet.

Same property net operating income on a cash basis increased for the period by 6.1% and the same property leased percentage increased by 5.7% for the quarter compared to the same period in 2011, primarily as a result of sustained leasing success and contractual rent escalations.

The total operating portfolio was approximately 92.1% leased on a weighted-average basis as of December 31, 2012, an increase of 4.9% as compared to the same period last year. Since the third quarter of 2010, the company’s total operating portfolio leased percentage on a weighted-average basis has increased 10.0%.

For the full year 2012, the company acquired six new properties for a total estimated investment of approximately $436.4 million comprising approximately 1.0 million rentable square feet, which were 93.3% leased at acquisition on a weighted-average basis.

At December 31, 2012, the company’s total portfolio comprised approximately 13.1 million rentable square feet with an additional 4.0 million square feet of development potential.

Quarterly and Annual Distributions

BioMed Realty Trust’s board of directors previously declared a fourth quarter 2012 dividend of $0.235 per share of common stock, representing a 9.3% increase over the company’s third quarter 2012 dividend of $0.215 per share, and a dividend of $0.46094 per share of the company’s 7.375% Series A Cumulative Redeemable Preferred Stock for the period from October 16, 2012 through January 15, 2013. For the full year 2012, the company declared dividends totaling $0.88 per common share, representing a 10.0% increase over common stock dividends declared in 2011, and $1.84376 per Series A preferred share.

Earnings Guidance

The company’s updated 2013 guidance for net income per diluted share and FFO per diluted share are set forth and reconciled below. Projected net income per diluted share and FFO per diluted share are based upon estimated, weighted-average diluted common shares outstanding of approximately 168.0 million.

The company continues to target new investment opportunities, including acquisitions and new development projects; however, the company’s 2013 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. In addition, these projections reflect approximately $5.8 million ($0.03 per diluted share) in other revenue related to Merck’s 2012 lease termination at one of the company’s properties.

The foregoing estimates are forward-looking and reflect management’s view of current and future market conditions, including certain assumptions with respect to leasing activity, rental rates, occupancy levels, interest rates, financings, acquisitions, development and redevelopment and the amount and timing of acquisitions, development and redevelopment activities. The company’s actual results may differ materially from these estimates.

Our FFO and CFFO available to common shares and partnership and LTIP units and a reconciliation to net income for the three and twelve months ended December 31, 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 twelve months ended December 31, 2012 and 2011 was as follows:

We present funds from operations, or FFO, FFO excluding acquisition-related expenses, or CFFO, and adjusted funds from operations, or AFFO, available to common shares and OP units because we consider them to be 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, CFFO and AFFO are 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, CFFO and AFFO exclude depreciation and amortization unique to real estate, gains and losses from property dispositions and extraordinary items, they provide performance measures that, when compared year over year, reflect 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 depreciable 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 CFFO 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 computations may differ from the methodologies 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 amounts 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 alternatives to net income/(loss) (computed in accordance with GAAP) as indicators of our financial performance or to cash flow from operating activities (computed in accordance with GAAP) as indicators of our liquidity, nor are they 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.
