The following analysis of our consolidated financial condition and results of operations should be read in conjunction with our unaudited consolidated financial statements and the notes thereto included elsewhere in this report.

OVERVIEW

Pennsylvania Real Estate Investment Trust, a Pennsylvania business trust founded in 1960 and one of the first equity REITs in the United States, has a primary investment focus on retail shopping malls and power centers located in the eastern half of the United States, primarily in the Mid-Atlantic region. Our portfolio currently consists of a total of 56 properties in 13 states, including 38 shopping malls, 14 strip and power centers and four properties under development. The retail properties have a total of 34.8 million square feet. The retail properties we consolidate for financial reporting purposes have a total of 30.3 million square feet, of which we own 23.8 million square feet. The retail properties that are owned by unconsolidated partnerships with third parties have a total of 4.5 million square feet, of which 2.9 million square feet are owned by such partnerships. The ground-up development portion of our portfolio contains four properties in two states, with two classified as "mixed use" (a combination of retail and other uses), one classified as retail and one classified as "other."

Our primary business is owning and operating shopping malls and power centers. We evaluate operating results and allocate resources on a property-by-property basis, and do not distinguish or evaluate our consolidated operations on a geographic basis. No individual property constitutes more than 10% of our consolidated revenue or assets, and thus the individual properties have been aggregated into one reportable segment based upon their similarities with regard to the nature of our properties and the nature of our tenants and operational processes, as well as long-term financial performance. In addition, no single tenant accounts for 10% or more of our consolidated revenue, and none of our properties are located outside the United States.

We hold our interests in our portfolio of properties through our operating partnership, PREIT Associates, L.P. ("PREIT Associates"). We are the sole general partner of PREIT Associates and, as of June 30, 2009, held a 94.9% controlling interest in PREIT Associates. We consolidate PREIT Associates for financial reporting purposes. We hold our investments in seven of the 52 retail properties and one of the four ground-up development properties in our portfolio through unconsolidated partnerships or tenancy in common relationships with third parties in which we own a 40% to 50% interest. We hold a noncontrolling interest in each unconsolidated partnership, and account for such partnerships using the equity method of accounting. We do not control any of these equity method investees for the following reasons:

• Except for two properties that we co-manage with our partner, the other entities are managed on a day-to-day basis by one of our partners as the managing general partner in each of the respective partnerships. In the case of the co-managed properties, all decisions in the ordinary course of business are made jointly.

• The managing general partner is responsible for establishing the operating and capital decisions of the partnership, including budgets, in the ordinary course of business.

• All major decisions of each partnership, such as the sale, refinancing, expansion or rehabilitation of the property, require the approval of all partners.

• Voting rights and the sharing of profits and losses are generally in proportion to the ownership percentages of each partner.

We hold our interest in three of our unconsolidated partnerships through tenancy in common arrangements. For each of these properties, title is held by us and another person or persons, and each has an undivided interest in the property. With respect to each of the three properties, under the applicable agreements between us and the other persons with ownership interests, we and such other persons have joint control because decisions regarding matters such as the sale, refinancing, expansion or rehabilitation of the property require the approval of both us and the other person (or at least one of the other persons) owning an interest in the property. Hence, we account for each of the properties using the equity method of accounting. The balance sheet items arising from these properties appear under the caption "Investments in partnerships, at equity." The income statement items arising from these properties appear in "Equity in income of partnerships."

We record the earnings from the unconsolidated partnerships using the equity method of accounting under the statement of operations caption entitled "Equity in income of partnerships," rather than consolidating the results of the unconsolidated partnerships with our results. Changes in our investments in these entities are recorded in the balance sheet caption entitled "Investment in partnerships, at equity." In the case of deficit investment balances, such amounts are recorded in distributions in excess of partnership investments.

For further information regarding our unconsolidated partnerships, see note 4 to our unaudited consolidated financial statements.

We provide our management, leasing and development services through PREIT Services, LLC, which generally manages and develops properties that we consolidate for financial reporting purposes, and PREIT-RUBIN, Inc. ("PRI"), which generally manages and develops properties that we own interests in through partnerships with third parties and properties that are owned by third parties in which we do not have an interest. One of our long-term objectives is to obtain managerial control of as many of our assets as possible. Due to the nature of our existing partnership arrangements, we cannot anticipate when this objective will be achieved, if at all.

Our revenue consists primarily of fixed rental income, additional rent in the form of expense reimbursements, and percentage rent (rent that is based on a percentage of our tenants' sales or a percentage of sales in excess of thresholds that are specified in the applicable leases) derived from our income producing retail properties. We also receive income from our real estate partnership investments and from the management and leasing services PRI provides.

Net loss was $4.2 million for the three months ended June 30, 2009, compared to net loss of $3.8 million for the three months ended June 30, 2008. For the three months ended June 30, 2009, net loss was affected by decreased occupancy as a result of tenant bankruptcies and store closings in 2008 and 2009, increased depreciation and amortization as a result of redevelopment and development assets having been placed in service, increased interest expense as a result of a higher aggregate debt balance and properties placed in service and increased property operating expenses compared to the three months ended June 30, 2008. The results of operations for the three months ended June 30, 2009 included gain on extinguishment of debt of $8.5 million and gains on the sales of real estate of $1.7 million. The results of operations for the three months ended June 30, 2008 included a gain from hedging activities of $2.0 million.

Net loss was $15.7 million for the six months ended June 30, 2009, compared to net loss of $6.9 million for the six months ended June 30, 2008. For the six months ended June 30, 2009, net loss was affected by decreased revenue and occupancy as a result of tenant bankruptcies and store closings in 2008 and 2009, increased depreciation and amortization as a result of redevelopment and development assets having been placed in service, increased interest expense as a result of a higher aggregate debt balance and properties placed in service and increased property operating expenses compared to the six months ended June 30, 2008. The results of operations for the six months ended June 30, 2009 included gain on extinguishment of debt of $9.8 million and gains on the sales of real estate of $1.7 million. The results of operations for the six months ended June 30, 2008 included a gain from hedging activities of $2.0 million.

CURRENT ECONOMIC DOWNTURN

We are subject to various risks and uncertainties in the ordinary course of business that could have adverse effects on our operating results and financial condition. The most significant external risks facing us today stem from the current downturn in the overall economy and challenging conditions in the capital and credit markets.

Substantially all of our revenue is generated from leases with retail tenants. The reduction in consumer spending as a result of declining consumer confidence and increasing unemployment has negatively affected, and might continue to negatively affect, the operations of many retail companies. Beginning in the second half of 2008 and continuing in 2009, the number of retail bankruptcies and store closings has increased. Retailers also have reduced the number of store openings planned for 2009 due to these economic conditions. These conditions have caused, and might continue to cause, our occupancy rates, revenue and net income to decline.

ACQUISITIONS, DISPOSITIONS, REDEVELOPMENT AND DEVELOPMENT ACTIVITIES

We record our acquisitions based on estimates of fair value, as determined by management, based on information available and on assumptions about future performance. These allocations are subject to revisions, in accordance with GAAP, during the twelve month periods following the closings of the respective acquisitions.

Acquisitions

In February 2008, we acquired a 49.9% ownership interest in Bala Cynwyd Associates, L.P., which owns One Cherry Hill Plaza, an office building located within the boundaries of our Cherry Hill Mall in Cherry Hill, New Jersey. In June 2009, we acquired an additional 49.9% ownership interest. See "Related Party Transactions" for further information about this transaction.

Dispositions

In June 2009, we sold a land parcel adjacent to North Hanover Mall in Hanover, Pennsylvania for $2.0 million. We recorded a gain of $1.4 million from this sale.

In June 2009, we sold a land parcel adjacent to Woodland Mall in Grand Rapids, Michigan for $2.7 million. The parcel contained a department store that was subject to a ground lease. We recorded a gain of $0.2 million from this sale.

In May 2009, we sold an outparcel and related land improvements containing an operating restaurant at Monroe Marketplace in Selinsgrove, Pennsylvania for $0.9 million. We recorded impairment of $0.1 million immediately prior to this transaction. No gain or loss was recorded from this sale.

Redevelopment and Development

We are engaged in the redevelopment of five of our consolidated properties. We might undertake redevelopment projects at additional properties in the future. These projects might include the introduction of residential, office or other uses to our properties. As of June 30, 2009, we had incurred $451.9 million of costs related to these five redevelopment properties. The costs identified to date to complete these projects, net of tenant reimbursement and tax credits, are expected to be approximately $40.1 million in the aggregate.

The following table sets forth the amount of our estimated total cost and the amounts invested as of June 30, 2009 in each redevelopment project:

                                        Estimated Project    Invested as of
          Redevelopment Project             Cost (1)          June 30, 2009
          Cherry Hill Mall             $     218.0 million   $ 206.0 million
          Plymouth Meeting Mall               96.6 million      89.9 million
          The Gallery at Market East          81.6 million      85.2 million
          Voorhees Town Center                83.0 million      61.6 million
          Wiregrass Commons Mall              12.8 million       9.2 million

                                       $     492.0 million   $ 451.9 million

(1) The estimated project cost is net of any expected tenant reimbursements, parcel sales, tax credits or other incentives.

We are engaged in the ground-up development of four retail and other mixed use projects that we believe meet the financial hurdles that we apply, given economic, market and other circumstances, although we do not expect to make material investments in these projects in the short term. As of June 30, 2009, we had incurred $88.7 million of costs related to these ground-up projects. We will evaluate the financing opportunities available to us at the time a project requires funding. In cases where the project is undertaken with a partner, our flexibility in funding the project might be restricted by the partnership agreement or the covenants contained in our Credit Facility, which limit our involvement or flexibility in such projects. We also own and manage one property that is now operating while some remaining development takes place.

We generally seek to develop these projects in areas that we believe evidence the likelihood of supporting additional retail development and have desirable population or income trends, and where we believe the projects have the potential for strong competitive positions. We will consider other uses of a property that would have synergies with our retail development and redevelopment based on several factors, including local demographics, market demand for other uses such as residential and office, and applicable land use regulations. We generally have several development projects under way at one time. These projects are typically in various stages of the development process. We manage all aspects of these undertakings, including market and trade area research, site selection, acquisition, preliminary development work, construction and leasing. We monitor our developments closely, including costs and tenant interest.

The following table sets forth the amount of our estimated total cost and the amounts invested as of June 30, 2009 in each ground-up development project:

                                                                      Actual/Expected
                              Estimated Project    Invested as of    Initial Occupancy
 Development Project               Cost (1)         June 30, 2009          Date
 Pitney Road Plaza            $     18.8 million   $  12.3 million                2009
 White Clay Point(2)            To be determined      43.2 million    To be determined
 Springhills                    To be determined      32.5 million    To be determined
 Pavilion at Market East(3)     To be determined       0.7 million    To be determined

                                                   $  88.7 million

(1) The estimated project cost is net of any expected tenant reimbursements, parcel sales, tax credits or other incentives.

(2) Amount invested as of June 30, 2009 does not reflect an $11.8 million impairment charge we recorded in 2008.

(3) The property is unconsolidated. The amount shown represents our share.

In connection with the redevelopment and the ground-up development projects listed above and other projects ongoing at our other properties, we have made contractual and other commitments in the form of tenant allowances, lease termination amounts and contracts with general contractors and other professional service providers. As of June 30, 2009, the unaccrued remainder to be paid against these contractual and other commitments was $24.7 million. The projects on which these commitments have been made have total expected remaining costs of $67.6 million. While we expect that the expenditures related to our redevelopment and development projects listed in this report will continue over the next several quarters, we believe that our construction in progress balance has peaked. Construction in progress represents the aggregate expenditures on projects less amounts placed in service. Generally, assets are placed in service upon substantial completion or when tenants begin occupancy and rent payments commence.

Continued uncertainty in the credit markets might negatively affect our ability to access additional debt financing on reasonable terms, or at all, which might negatively affect our ability to fund our redevelopment and development projects and other business initiatives. A continued prolonged downturn in the credit markets might cause us to seek alternative sources of capital or financing, which could be less attractive and might require us to adjust our business plan accordingly. See "-Liquidity and Capital Resources."

OFF BALANCE SHEET ARRANGEMENTS

We have no material off-balance sheet items other than the partnerships described in note 4 to the unaudited consolidated financial statements and in the "Overview" section above.

RELATED PARTY TRANSACTIONS

Bala Cynwyd Associates, L.P.

In January 2008, PREIT Associates and another subsidiary of PREIT entered into a Contribution Agreement with Bala Cynwyd Associates, L.P. ("BCA"), City Line Associates ("CLA"), Ronald Rubin, George Rubin, Joseph Coradino, and two other individuals to acquire all of the partnership interests in BCA. BCA entered into a tax deferred exchange agreement with the owners of One Cherry Hill Plaza, an office building located within the boundaries of our Cherry Hill Mall (the "Office Building"), to acquire title to the Office Building in exchange for an office building located in Bala Cynwyd, Pennsylvania owned by BCA.

Ronald Rubin, George Rubin, Joseph Coradino and two other individuals (collectively, the "Individuals") own 100% of CLA, a limited partnership that owned 50% of BCA immediately prior to closing. Each of Ronald Rubin and George Rubin owns 40.53% of the partnership interests in CLA, and Joseph Coradino owns 3.16% of the partnership interests. Immediately prior to the closing, BCA redeemed 50% of its partnership interests, which were held by a third party. At the initial closing under the Contribution Agreement and in exchange for a 0.1% general partner interest and 49.8% limited partner interest in BCA, we made a capital contribution to BCA in an approximate amount of $3.9 million.

In June 2009, a second closing occurred in which we acquired an additional 49.9% of the limited partner interest in BCA from the Individuals for 140,745 OP Units and a nominal cash amount. A third closing is expected to occur pursuant to a put/call agreement

approximately one year after the second closing, at which time we will acquire the remaining interest in BCA from the Individuals in exchange for 564 OP Units and a nominal cash amount. None of Ronald Rubin, George Rubin or Joseph Coradino received any consideration from us in connection with the first closing.

The acquisition of the Office Building was financed in part by a mortgage loan with a principal amount of $8.0 million.

PREIT and PREIT Associates have agreed to provide tax protection to the Individuals in connection with taxes arising from a sale of the Office Building during the eight years following the initial closing.

In accordance with our related party transactions policy, a special committee consisting exclusively of independent members of our Board of Trustees considered and approved the terms of this transaction. The approval was subject to final approval of our Board of Trustees, and the disinterested members of our Board of Trustees approved the transaction.

Other

PRI provides management, leasing and development services for eight properties owned by partnerships and other entities in which certain officers or trustees of the Company and of PRI or members of their immediate families and affiliated entities have indirect ownership interests. Total revenue earned by PRI for such services was $0.2 million and $0.3 million for the three months ended June 30, 2009 and 2008, respectively, and $0.4 million for each of the six months ended June 30, 2009 and 2008.

We lease our principal executive offices from Bellevue Associates (the "Landlord"). Ronald Rubin and George F. Rubin, collectively with members of their immediate families and affiliated entities, own approximately a 50% interest in the Landlord. The office lease has a 10 year term that commenced on November 1, 2004. Our base rent is $1.4 million per year during the first five years of the office lease and $1.5 million per year during the second five years. Total rent expense under this lease was $0.4 million for each of the three months ended June 30, 2009 and 2008, and $0.8 million for each of the six months ended June 30, 2009 and 2008.

We use an airplane in which Ronald Rubin owns a fractional interest. We did not incur any expenses in the first six months of 2009 for this service. We paid $40,000 in the three months ended June 30, 2008, and $94,000 in the six months ended June 30, 2008 for flight time used by employees on Company-related business.

CRITICAL ACCOUNTING POLICIES

Critical accounting policies are those that require the application of management's most difficult, subjective, or complex judgments, often because of the need to make estimates about the effect of matters that are inherently uncertain and that may change in subsequent periods. In preparing the consolidated financial statements, management has made estimates and assumptions that affect the reported amounts of assets and liabilities at the date of the financial statements, and the reported amounts of revenue and expenses during the reporting periods. In preparing the financial statements, management has utilized available information, including our past history, industry standards and the current economic environment, among other factors, in forming its estimates and judgments, giving due consideration to materiality. Actual results may differ from these estimates. In addition, other companies may utilize different estimates, which may impact the comparability of our results of operations to those of companies in similar businesses.

Our management makes complex or subjective assumptions and judgments in connection with applying its critical accounting policies. In making these judgments and assumptions, management considers, among other factors:

• events and changes in property, market and economic conditions;

• estimated future cash flows from property operations; and

• the risk of loss on specific accounts or amounts.

The estimates and assumptions made by management in applying critical accounting policies have not changed materially during 2009 and 2008, and none of these estimates or assumptions have proven to be materially incorrect or resulted in our recording any significant adjustments relating to prior periods. We will continue to monitor the key factors underlying our estimates and judgments, but no change is currently expected. See our Annual Report on Form 10-K for the year ended December 31, 2008, as amended, for a summary of the accounting policies that management believes are critical to the preparation of the consolidated financial statements.

Asset Impairment

Real estate investments and related intangible assets are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of the property might not be recoverable. A property to be held and used is considered impaired only if management's estimate of the aggregate future cash flows, less estimated capital expenditures, to be generated by the property, undiscounted and without interest charges, are less than the carrying value of the property. The estimate takes into consideration factors such as expected future operating income, trends and prospects, as well as the effects of demand, competition, and other factors. In addition, these estimates may consider a probability weighted cash flow estimation approach when alternative courses of action to recover the carrying amount of a long-lived asset are under consideration or when a range of possible values is estimated.

The determination of undiscounted cash flows requires significant estimates by management, including the expected course of action at the balance sheet date that would lead to such cash flows. Subsequent changes in estimated undiscounted cash flows arising from changes in anticipated action to be taken with respect to the property could impact the determination of whether an impairment exists and whether the effects could materially impact our net income. To the extent estimated undiscounted cash flows are less than the carrying value of the property, the loss will be measured as the excess of the carrying amount of the property over the fair value of the property.

We test for impairment in several situations, including when current or projected cash flows from a real estate investment are significantly less than budgeted cash flows, when it becomes more likely than not that a property will be sold before the end of its previously estimated useful life, or when other events or changes in circumstances indicate that an asset's carrying value might not be recoverable. In the evaluation of the impairment of our assets, we make many assumptions and estimates, including:

• projected cash flows, both from operations and from a hypothetical disposition;

• expected useful life and holding period;

• future required capital expenditures; and

• fair values, including consideration of capitalization rates, discount rates and comparable selling prices.

As a preliminary indicator to determine if the carrying value of a property might not be recovered by undiscounted cash flows as of June 30, 2009, we utilized a five-year planning model based on existing tenants, expectations about future rental activity and expense levels. For periods beyond the five-year model, we assumed a 2.0% rate of growth for cash flows over the estimated useful lives of the individual properties, which is lower than the historical assumed growth rate utilized because of the current economic conditions. As a result of this test, we did not identify any properties that required further consideration of property and market specific conditions or factors to determine if the property was impaired.

An other than temporary impairment of an investment in an unconsolidated joint venture is recognized when the carrying value of the investment is not considered recoverable based on evaluation of the severity and duration of the decline in fair value, including the results of discounted cash flow and other valuation techniques. To the extent impairment has occurred, the excess carrying value of the asset over its estimated fair value is charged to income.

RESULTS OF OPERATIONS

Comparison of Three and Six Months Ended June 30, 2009 and 2008

Overview

Our results in recent periods have been significantly affected by challenging conditions in the economy and by ongoing redevelopment initiatives that were in various stages at several of our consolidated mall properties. While we might undertake a redevelopment project to maximize the long-term performance of the property, in the short term, the operations and performance of the property, as measured by occupancy and net operating income, can be negatively affected by the project. For the three and six months ended June 30, 2009, net loss was . . .
