Brandywine Realty Trust Announces Second Quarter 2018 Results

and Narrows 2018 Guidance

Philadelphia, PA, July 19, 2018 — Brandywine Realty Trust (NYSE:BDN) today reported its financial and operating results for the three and six-month periods ended June 30, 2018.

Management Comments

“We remain excited about the strong progression of our 2018 business plan,” stated Gerard H. Sweeney, President and Chief Executive Officer for Brandywine Realty Trust. “Market conditions remain strong and we continue to have a robust leasing pipeline.  Our 2018 revenue target is now 92% executed resulting in strong quarterly metrics, including a 22.8% increase in quarterly GAAP mark-to-market rents.  Our development pipeline aggregating $270 million is now 92% leased at a weighted-average cash yield on cost of 9.2%. In Austin, Texas, we achieved a significant milestone by receiving zoning approval for our Broadmoor campus that will allow us to transform the property into a six million square foot, mixed-use, transit-oriented urban environment. Our balance sheet strengthening strategy was further enhanced by extending our unsecured line of credit through July 2022 while reducing borrowing costs.  After a successful second quarter we are narrowing our 2018 FFO guidance range from $1.34 to $1.42 to $1.35 to $1.41 per diluted share.”

Forward-Looking Statements

Estimates of future earnings per share, FFO per share, common share dividend distributions and certain other statements in this release constitute “forward-looking statements” within the meaning of the Private Securities Litigation Reform Act of 1995.  Such forward-looking statements involve known and unknown risks, uncertainties and other factors that may cause our and our affiliates’ actual results, performance, achievements or transactions to be materially different from any future results, performance, achievements or transactions expressed or implied by such forward-looking statements.  Such risks, uncertainties and other factors relate to, among others: our ability to lease vacant space and to renew or relet space under expiring leases at expected levels; competition with other real estate companies for tenants; the potential loss or bankruptcy of major tenants; interest rate levels; the availability of debt, equity or other financing; risks of acquisitions, dispositions and developments, including the cost of construction delays and cost overruns; unanticipated operating and capital costs; our ability to obtain adequate insurance, including coverage for terrorist acts; dependence upon certain geographic markets; and general and local economic and real estate conditions, including the extent and duration of adverse changes that affect the industries in which our tenants operate.  The declaration and payment of future dividends (both timing and amount) is subject to the determination of our Board of Trustees, in its sole discretion, after considering various factors, including the Company's financial condition, historical and forecast operating results, and available cash flow, as well as any applicable laws and contractual covenants and any other relevant factors.  The Company's practice regarding payment of dividends may be modified at any time and from time to time.  Additional information on factors which could impact us and the forward-looking statements contained herein are included in our filings with the Securities and Exchange Commission, including our Form 10-K for the year ended December 31, 2017.  We assume no obligation to update or supplement forward-looking statements that become untrue because of subsequent events except as required by law.

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

-4-

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 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 interest in the Operating Partnership 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 interest in property partnerships.  In some cases we also present NOI on a cash basis, which is NOI after eliminating the effects 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 to cash flows as a measure of the Company's liquidity or its ability to make distributions.  NOI is a useful measure for evaluating the operating performance of our properties, as it excludes certain components from net income available to common shareholders in order to provide results that are more closely related to a property's results of operations.  NOI is used internally to evaluate the performance of our operating segments and to make decisions about resource allocations.  We concluded that NOI provides useful information to investors regarding our financial condition and results of operations, as it reflects only the income and expense items incurred at the property level, as well as the impact on operations from trends in occupancy rates, rental rates, operating costs and acquisition and development activity on an unlevered basis.

Core Portfolio

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