Radnor, PA, April 20, 2016 — Brandywine Realty Trust (NYSE:BDN) today reported its financial and operating results for the three months ended March 31, 2016.

Management Comments

“During the first quarter, we have executed several landmark transactions that transformed our balance sheet, improved our operating platform and provided additional growth opportunities going forward,” stated Gerard H. Sweeney, President and Chief Executive Officer for Brandywine Realty Trust.  “We made excellent progress on our 2016 business plan completing 90% of our $850 million disposition target as we continue reducing or exiting non-core markets. Our remaining portfolio has produced strong operating results. We have increased our speculative revenue target by 12.9% and have completed 76% of our operational business plan.  Leasing at FMC was strong with 85,000 square feet of leases signed during the quarter bringing us to 75% leased. We are also excited about being selected by Drexel University as the Master Developer for Schuylkill Yards, a 14-acre site in the heart of University City that will provide excellent growth for years to come. Based on our strong first quarter results, we are raising our 2016 adjusted FFO guidance from $1.23 to $1.30 per diluted share to $1.26 to $1.32 per diluted share.”

Non-GAAP Supplemental Financial Measures

We compute our financial results in accordance with generally accepted accounting principles (GAAP).  Although FFO and NOI are non-GAAP financial measures, we believe that FFO and NOI calculations are helpful to shareholders and potential investors and are widely recognized measures of real estate investment trust performance.  At the end of this press release, we have provided a reconciliation of the non-GAAP financial measures to the most directly comparable GAAP measure.

Funds from Operations (FFO)

We compute FFO in accordance with standards established by the National Association of Real Estate Investment Trusts (NAREIT), which may not be comparable to FFO reported by other REITs that do not compute FFO in accordance with the NAREIT definition, or that interpret the NAREIT definition differently than us.  NAREIT defines FFO as net income (loss) before non-controlling interests and excluding gains (losses) on sales of depreciable operating property, impairment losses on depreciable consolidated real estate, impairment losses on investments in unconsolidated real estate ventures and extraordinary items (computed in accordance with GAAP); plus real estate related depreciation and amortization (excluding amortization of deferred financing costs), and after similar adjustments for unconsolidated joint ventures.  Net income, the GAAP measure that we believe to be most directly comparable to FFO, includes depreciation and amortization expenses, gains or losses on property sales, extraordinary items and non-controlling interests.  To facilitate a clear understanding of our historical operating results, FFO should be examined in conjunction with net income (determined in accordance with GAAP) as presented in the financial statements included elsewhere in this release.  FFO does not represent cash flow from operating activities (determined in accordance with GAAP) and should not be considered to be an alternative to net income (loss) (determined in accordance with GAAP) as an indication of our financial performance or to be an alternative to cash flow from operating activities (determined in accordance with GAAP) as a measure of our liquidity, nor is it indicative of funds available for our cash needs, including our ability to make cash distributions to shareholders.

Net Operating Income (NOI)

NOI is a non-GAAP financial measure equal to net income available to common shareholders, the most directly comparable GAAP financial measure, plus corporate general and administrative expense, depreciation and amortization, interest expense, non-controlling interests and losses from early extinguishment of debt, less interest income, development and management income, gains from property dispositions, gains on sale from discontinued operations, gains on early extinguishment of debt, income from discontinued operations, income from unconsolidated joint ventures and non-controlling interests.  In some cases, we also present NOI on a cash basis, which is NOI after eliminating the effect of straight-lining of rent and deferred market intangible amortization.  NOI presented by us may not be comparable to NOI reported by other REITs that define NOI differently.  NOI should not be considered an alternative to net income as an indication of our performance, or as an alternative to cash flow from operating activities as a measure of our liquidity or ability to make cash distributions to shareholders.

Core Portfolio

Our core portfolio is comprised of our wholly-owned properties, excluding any properties currently in development, re-development or re-entitlement.
