Fourth Quarter 2011 Highlights

Subsequent to quarter end, the company entered into a definitive agreement to purchase the Cambridge Place property in Cambridge, Massachusetts for approximately $119.0 million.

Alan D. Gold, Chairman and Chief Executive Officer of BioMed Realty, remarked, “The fourth quarter results demonstrate, once again, the long-term value of sure and steady execution of our business model. Our strong financial results, led by record rental revenues for the eighth consecutive quarter, were driven by continued robust gross leasing volume of 253,900 square feet, which pushed our final five-quarter leasing volume to two million square feet and 165% of our original goal. In addition, we opportunistically expanded our footprint in Cambridge, Massachusetts, the world’s foremost center of life science research and discovery, to 3.2 million square feet by taking full ownership of the Rogers Street properties during the quarter, and including the acquisition of Cambridge Place, which is expected to close this month. Our sustained operating success is a byproduct of providing optimal laboratory and office space for leading life science organizations, amassing the industry’s highest-quality portfolio in the best locations, and creating trusted relationships with our tenants by understanding their unique needs.”

“Our full-year 2011 results were outstanding,” said Kent Griffin, President and Chief Operating Officer of BioMed Realty. “We continue to deliver consistent bottom-line success driven by sustained leasing activity and strong execution across the board. In addition, we made $431 million of tactical new investments which allow us to develop scale, create attractive growth opportunities and produce strong risk-adjusted total returns. We continued to exercise steady, pro-active balance sheet management supporting the continued execution on our proven business model and creating long-term value for our stockholders. Our long-term financial success is tied to the quality of our assets and their locations, and equally attributable to our deep team of talent and coordinated service delivery which supports the world’s most inspiring life science research.”

Our FFO available to common shares and partnership and LTIP units and a reconciliation to net income for the three and twelve months ended December 31, 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 twelve months ended December 31, 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. As defined by NAREIT, FFO represents net income (computed in accordance with GAAP), excluding gains (or losses) from sales of property, impairment charges, 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.
