Brandywine Realty Trust Announces $0.32 FFO per Diluted Share for Second Quarter 2011

Raises 2011 FFO Guidance Range to $1.32 to $1.36 per Diluted Share

Radnor, PA, July 27, 2011 — Brandywine Realty Trust (NYSE:BDN), a real estate investment trust focused on the ownership, management and development of Class A, suburban and urban office properties in the mid-Atlantic region and other selected markets throughout the United States, today reported its financial and operating results for the three and six-month periods ended June 30, 2011.

“The second quarter results reflect solid execution of our 2011 business plan,” stated Gerard H. Sweeney, President and Chief Executive Officer of Brandywine Realty Trust. “We continue to generate strong leasing activity during this time of market recovery, having signed nearly 2.5 million square feet of leases in the first six months of 2011. All operating and financial metrics equaled or exceeded our business plan targets with continued acceleration of our 2011 revenue production. As such, we are increasing both the bottom and top of our 2011 FFO guidance and look forward to a strong finish over the balance of the year.”

Financial Highlights — Second Quarter

	•		Net loss allocated to common shares totaled ($8.2 million) or ($0.06) per diluted share in the second quarter of 2011 compared to ($7.6 million) or ($0.06) per diluted share in the second quarter of 2010. Our weighted average diluted share count increased to 135.3 million shares in the second quarter of 2011 from 131.5 million shares in the second quarter of 2010 due primarily to our periodic issuance of 6.4 million common shares under our continuous equity program since its inception in March 2010 through June 30, 2011.
	•		Funds from operations available to common shares and units (FFO) in the second quarter of 2011 totaled $47.5 million or $0.32 per diluted share compared to $46.6 million or $0.34 per diluted share in the second quarter of 2010. Our second quarter 2011 FFO payout ratio was 46.9% ($0.15 common share dividend paid / $0.32 FFO per share). Our weighted average fully diluted share/unit count for FFO calculations increased to 146.6 million shares/units in the second quarter of 2011 from 136.1 million shares/units in the second quarter of 2010 due primarily to our issuance in August 2010 of 7.1 million units in connection with our Three Logan Square acquisition as well as the aforementioned issuance of 6.4 million shares under our continuous equity program.
	•		In the second quarter of 2011, we incurred $22.6 million of revenue maintaining capital expenditures reflecting disbursements related to current and previously executed leases which along with other adjustments to FFO, resulted in $20.5 million of cash available for distribution (CAD) or $0.15 per diluted share compared to $31.9 million of CAD or $0.23 per diluted share in the second quarter of 2010 when we incurred $12.5 million of revenue maintaining capital expenditures. Our second quarter 2011 CAD payout ratio was 100.0% ($0.15 common share dividend paid / $0.15 CAD per share). We exclude the Three Logan Square units from the CAD share/unit count because they do not receive or accrue distributions until after the one-year anniversary of the associated transaction.

Financial Highlights — Six Months

•

Net loss allocated to common shares totaled ($10.8 million) or ($0.08) per diluted share in the first six months of 2011 compared to net loss of ($10.0 million) or ($0.08) per diluted share in the first six months of 2010.

	•		FFO available to common shares and units in the first six months of 2011 totaled $95.7 million or $0.65 per diluted share compared to $92.3 million or $0.68 per diluted share in the first six months of 2010. Our FFO payout ratio for the first six months of 2011 was 46.2% ($0.30 common share dividend paid / $0.65 FFO per share).
	•		During the first six months of 2011, we incurred $41.3 million of revenue maintaining capital expenditures which along with our other adjustments to FFO, resulted in $45.9 million of CAD or $0.33 per diluted share compared to $66.5 million of CAD or $0.49 per diluted share for the first six months of 2010 when we incurred $20.8 million of revenue maintaining capital expenditures. Our CAD payout ratio for the first six months of 2011 was 90.9% ($0.30 common share dividend paid / $0.33 CAD per share).

Portfolio Highlights

	•		In the second quarter of 2011, our net operating income (NOI) excluding termination revenues and other income items declined 4.7% on a GAAP basis and 6.9% on a cash basis for our 229 same store properties which were 85.7% and 86.3% occupied on June 30, 2011 and June 30, 2010, respectively.
	•		During the second quarter of 2011, we commenced occupancy on 1,089,427 square feet of total leasing activity including 475,439 square feet of renewals, 468,264 square feet of new leases and 145,724 square feet of tenant expansions. We have an additional 731,452 square feet of executed new leasing in place scheduled to commence subsequent to June 30, 2011.
	•		During the second quarter of 2011, we achieved a 65.3% retention rate in our core portfolio with positive net absorption of 137,999 square feet. During the second quarter of 2011, we experienced a 1.7% decline on our renewal rental rates and a 1.8% increase on our new lease/expansion rental rates, both on a GAAP basis.
	•		At June 30, 2011, our core portfolio of 235 properties comprising 25.7 million square feet was 85.8% occupied and 88.7% leased (reflecting new leases commencing after June 30, 2011).

Investment Highlights

•

During the second quarter of 2011, we completed the sale of Three Greentree Center, a 13.9% occupied 69,300 square foot office building in Marlton, NJ, for gross proceeds of $5.9 million and realized a $3.8 million gain on the sale. We used the net proceeds from the sale for general corporate purposes and to reduce the outstanding balance on our unsecured revolving credit facility.

Capital Markets Highlights

	•		During the second quarter of 2011 as previously reported, we issued 0.5 million shares of our common stock under our continuous equity program realizing $5.8 million of net proceeds. Since commencing the program in March 2010, we have issued a total of 6.4 million shares under the 15.0 million share program raising $78.8 million of net proceeds and have remaining authorization for the future issuance of 8.6 million shares of common stock.
	•		During the second quarter of 2011 as previously reported, we closed a $325.0 million senior note financing due April 15, 2018 with a coupon rate of 4.95% and a yield to maturity of 5.137% realizing $318.9 million of net proceeds.
	•		During the second quarter of 2011, we repurchased $21.5 million of our 2012 unsecured notes and $1.4 million of our 2015 unsecured notes in a series of open-market transactions and incurred an aggregate loss of ($1.0 million) on the early extinguishment of debt. We funded these repurchases with draws on our unsecured revolving credit facility and with available corporate funds.

	•		During the second quarter of 2011, we used available corporate funds and draws on our revolving credit facility to pre-pay three mortgage loans without penalty — $20.2 million Arboretum I/II/III/V, $55.7 million Midlantic/Lenox/DCC1 and $38.7 million Research Office Center — and realized aggregate gains on these repayments of $0.3 million. Subsequent to quarter end, we used available corporate funds and a draw on our unsecured revolving credit facility to pre-pay without penalty our $60.0 million One Logan Square mortgage loan, and will accelerate $0.8 million of associated deferred costs in the third quarter of 2011 as a result of this prepayment.
	•		At June 30, 2011, our net debt to gross assets measured 44.9% and we had $42.0 million outstanding on our $600.0 million unsecured revolving credit facility with $547.7 million available for use and drawdown.
	•		For the quarter ended June 30, 2011, we achieved a 2.4 EBITDA to interest coverage ratio and a 7.4 ratio of net debt to annualized quarterly EBITDA based on consolidated EBITDA excluding non-recurring items, and inclusive of our pro rata share of unconsolidated EBITDA, interest and net debt.

Distributions

On June 1, 2011, our Board of Trustees declared a quarterly dividend distribution of $0.15 per common share that was paid on July 20, 2011 to shareholders of record as of July 6, 2011, bringing total year-to-date 2011 dividend payments to $0.45 per common share. Our Board also declared regular quarterly dividend distributions of $0.46875 per 7.50% Series C Cumulative Redeemable Preferred Share and $0.460938 per 7.375% Series D Cumulative Redeemable Preferred Share that were paid on July 15, 2011 to holders of record as of June 30, 2011 of the Series C and Series D Preferred Shares, respectively.

2011 Earnings and FFO Guidance

Based on current plans and assumptions and subject to the risks and uncertainties more fully described in our Securities and Exchange Commission filings, we are revising our previously issued guidance for full year 2011 FFO per diluted share to be in a range of $1.32 to $1.36 versus the prior range of $1.27 to $1.34. This guidance is provided for informational purposes and is subject to change. The following is a reconciliation of the calculation of 2011 FFO per diluted share and earnings per diluted share:

Guidance for 2011		Range or Value
Earnings (loss) per diluted share allocated to common shareholders		$	(0.19	)		to				$	(0.15	)
Plus: real estate depreciation and amortization			1.51								1.51
FFO per diluted share		$	1.32			to				$	1.36

Our 2011 FFO guidance does not include income arising from sales or impairments which may be taken in the future, and does not include any income from the sale of undepreciated real estate in accordance with our current practice. Our 2011 earnings and FFO per diluted share each reflect $0.07 per diluted share of net non-cash income attributable to the first of five annual pro-rata recognitions beginning in the third quarter of 2011 equal to 20% of the total net impact of the previously disclosed rehabilitation tax credit financing on the 30^th Street Post Office. Other key assumptions include slightly improved occupancy levels by year-end 2011, a 1.5-3.0% decline (GAAP) in overall lease rates, a resulting 3.0-4.0% decline in 2011 same store NOI (GAAP) and 147.0 million fully diluted weighted average shares.

Non-GAAP Supplemental Financial Measures

We compute our financial results in accordance with generally accepted accounting principles (GAAP). Although FFO, NOI and CAD are non-GAAP financial measures, we believe that FFO, NOI and CAD 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 property 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.

Cash Available for Distribution (CAD)

CAD is a non-GAAP financial measure that is not intended as an alternative to cash flow from operating activities as determined under GAAP. CAD is presented solely as a supplemental disclosure with respect to liquidity because we believe it provides useful information regarding our ability to fund our distributions. Because other companies do not necessarily calculate CAD the same way as we do, our presentation of CAD may not be comparable to similarly titled measures provided by other companies.

Revenue Maintaining Capital Expenditures

Revenue maintaining capital expenditures, a non-GAAP financial measure, are a component of our CAD calculation and represent the portion of capital expenditures required to maintain our current level of funds available for distribution. Revenue maintaining capital expenditures include current tenant improvement and allowance expenditures for all tenant spaces that have been owned for at least one year, and that were not vacant during the twelve-month period prior to the date that the tenant improvement or allowance expenditure was incurred. Revenue maintaining capital expenditures also include other expenditures intended to maintain our current revenue base. Accordingly, we exclude capital expenditures related to development and redevelopment projects, as well as certain projects at our core properties that are intended to attract prospective tenants in order to increase revenues and/or occupancy rates.
