2. BASIS OF PRESENTATION

Basis of Presentation

The consolidated financial statements have been prepared by the Company pursuant to the rules and regulations of the U.S. Securities and Exchange Commission (“SEC”) for interim financial statements. Certain information and footnote disclosures normally included in the annual financial statements prepared in accordance with accounting principles generally accepted in the United States of America (“GAAP”) have been condensed or omitted pursuant to such rules and regulations. In the opinion of management, all adjustments consist solely of normal recurring matters, and result in a fair statement of the financial position of the Company as of September 30, 2024, the results of its operations for the three and nine months ended September 30, 2024 and 2023 and its cash flows for the nine months ended September 30, 2024 and 2023. The results of operations for such interim periods are not necessarily indicative of the results for a full year. These consolidated financial statements should be read in conjunction with the Parent Company’s and the Operating Partnership’s consolidated financial statements and footnotes included in their combined Annual Report on Form 10-K for the year ended December 31, 2023 filed with the SEC on February 22, 2024.

The consolidated balance sheet at December 31, 2023 has been derived from the audited financial statements as of that date but does not include all the information and footnotes required by GAAP for complete financial statements. The Company’s Annual Report on Form 10-K for the year ended December 31, 2023 contains a discussion of the Company’s significant accounting policies under Note 2, “Summary of Significant Accounting Policies”. There have been no material changes in the Company’s significant accounting policies since December 31, 2023.

Use of Estimates

The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenue and expenses during the reporting period. The estimates and assumptions include, but are not limited to, the amount and timing of development/redevelopment costs and of Company obligations for such costs, including costs incurred through unconsolidated real estate ventures. The estimates and assumptions for development/redevelopment cost are highly judgmental, cover significant future time horizons and are sensitive to cost escalations, sales price escalations and timing and pricing of leasing activity, all of which may be affected by expectations about future market or economic conditions. Actual results could differ from these and other estimates.

Recent Accounting Pronouncements

In November 2023, the FASB issued ASU 2023-07, Segment Reporting (Topic 280). The new standard requires enhanced disclosures about significant segment expenses and other segment items and requires companies to disclose all annual disclosures about segments in interim periods. The new standard also permits companies to disclose more than one measure of segment profit or loss, requires disclosure of the title and position of the Chief Operating Decision Maker, and requires companies with a single reportable segment to provide all disclosures required by Topic 280. The new standard is effective for fiscal years beginning after December 15, 2023, and interim periods within fiscal years beginning after December 15, 2024. Early adoption is permitted and companies are required to apply the ASU retrospectively to all periods presented. The Company does not expect the standard to have a material impact on its consolidated financial statements.

Mid-Atlantic Office Venture

On August 9, 2024 as part of a loan restructuring for the Mid-Atlantic Office Venture which included forgiveness of $39.8 million of the Venture's debt, the Company funded its $4.1 million portion of a lender pay down for the venture. Brandywine’s contribution is an equity method investment in the Mid-Atlantic Office JV. The Company recorded the contribution to Investment in unconsolidated real estate ventures on the consolidated balance sheet. The Mid-Atlantic Office Venture has liquidation rights and priorities that are different from ownership percentages. As such, equity in earnings is determined using the hypothetical liquidation book value (“HLBV”) method. Income or loss is recorded based on changes in what would be received should the entity liquidate all of its assets (as valued in accordance with GAAP) and distribute the resulting proceeds based on the terms of the respective agreements. The HLBV method is a balance sheet focused approach commonly applied to equity investments where cash distribution percentages vary at different points in time and are not directly linked to an equity holder’s ownership percentage.

Commerce Square Venture

On August 26, 2024, the Company agreed to fund and has subsequently funded, in November 2024, an additional $23 million common equity contribution to the Commerce Square Venture, the proceeds from which will be used by the Commerce Square Venture to pay down the preferred equity position of the Company’s current partner in the Commerce Square Venture, thereby increasing a portion of the Company’s ownership interest in the Commerce Square Venture to 84%. In connection with the Company’s funding agreement, the Commerce Square Venture recorded impairment charges of $116.5 million during the quarter ended September 30, 2024 based on the excess of the carrying value of the properties over their estimated fair value. The estimated fair value is considered Level 3 in accordance with ASC 820 and was based upon the third party appraisal.

8. FAIR VALUE OF FINANCIAL INSTRUMENTS

Financial assets and liabilities recorded on the Company's consolidated balance sheets are categorized based on the inputs to the valuation techniques as follows:

•Level 1 inputs are quoted prices (unadjusted) in active markets for identical assets or liabilities that the Company has the ability to access;

•Level 2 inputs are inputs, other than quoted prices included in Level 1, which are observable for the asset or liability, either directly or indirectly. Level 2 inputs may include quoted prices for similar assets and liabilities in active markets, as well as inputs that are observable for the asset or liability (other than quoted prices), such as interest rates, foreign exchange rates, and yield curves that are observable at commonly quoted intervals; and

•Level 3 inputs are unobservable inputs for the asset or liability, which is typically based on an entity’s own assumptions, as there is little, if any, related market activity or information.

The Company determined the fair values disclosed below using available market information and discounted cash flow analyses as of September 30, 2024 and December 31, 2023, respectively. The discount rate used in calculating fair value is the sum of the current risk free rate and the risk premium on the date of measurement of the instruments or obligations. Considerable judgment is necessary to interpret market data and to develop the related estimates of fair value. Accordingly, the estimates presented are not necessarily indicative of the amounts that the Company could realize upon disposition. The use of different estimates and valuation methodologies may have a material effect on the fair value amounts shown. The Company believes that the carrying amounts reflected in the consolidated balance sheets at September 30, 2024 and December 31, 2023 approximate the fair values for cash and cash equivalents, accounts receivable, other assets and liabilities, accounts payable and accrued expenses because they are short-term in duration. The following are financial instruments for which the Company’s estimates of fair value differ from the carrying amounts (in thousands):

(a)Net of deferred financing costs of $10.2 million and $5.8 million for unsecured notes payable, $1.2 million and $1.5 million for variable rate debt and $2.6 million and $3.2 million for secured fixed rate debt as of September 30, 2024 and December 31, 2023.

The Company used quoted market prices as of September 30, 2024 and December 31, 2023 to value the unsecured notes payable and, as such, categorized them as Level 2.

The inputs utilized to determine the fair value of the Company’s variable rate debt are categorized as Level 3. The fair value of the variable rate debt was determined using a discounted cash flow model that considered borrowing rates available to the Company for loans with similar terms and characteristics.

The inputs utilized to determine fair value of the Company’s notes receivable are unobservable and, as such, were categorized as Level 3. Fair value was determined using a discounted cash flow model that considered the contractual interest and principal payments discounted at a blended interest rate of the notes receivable.

For the Company’s Level 3 financial instruments for which fair value is disclosed, an increase in the discount rate used to determine fair value would result in a decrease to the fair value. Conversely, a decrease in the discount rate would result in an increase to the fair value.

Disclosure about the fair value of financial instruments is based upon pertinent information available to management as of September 30, 2024 and December 31, 2023. Although management is not aware of any factors that would significantly affect the fair value amounts, such amounts were not comprehensively revalued for purposes of these financial statements since September 30, 2024. Current estimates of fair value may differ from the amounts presented herein.

9. DERIVATIVE FINANCIAL INSTRUMENTS

The following table summarizes the terms and fair values of the Company’s derivative financial instruments as of September 30, 2024 and December 31, 2023. The notional amounts provide an indication of the extent of the Company’s involvement in these instruments at that time, but do not represent exposure to credit, interest rate or market risks (amounts presented in thousands).

(a)Hedging unsecured variable rate debt.

The Company measures its derivative instruments at fair value and records them in “Other assets” and “Other liabilities” on the Company’s consolidated balance sheets.

Although the Company has determined that the majority of the inputs used to value its derivatives fall within Level 2 of the fair value hierarchy, the credit valuation adjustments associated with its derivatives utilize Level 3 inputs, such as estimates of current credit spreads to evaluate the likelihood of default by itself and its counterparties. The Company has assessed the significance of the impact of the credit valuation adjustments on the overall valuation of its derivative positions and has determined that the credit valuation adjustments are not significant to the overall valuation of its derivatives. As a result, the Company has determined that the inputs utilized to determine the fair value of derivative instruments are classified in Level 2 of the fair value hierarchy.

10. LIMITED PARTNERS’ NONCONTROLLING INTERESTS IN THE PARENT COMPANY

Noncontrolling interests in the Parent Company’s financial statements relate to redeemable common limited partnership interests in the Operating Partnership held by parties other than the Parent Company and properties which are consolidated but not wholly-owned by the Operating Partnership.

Under the applicable accounting guidance, the redemption value of the redeemable common limited partnership units is carried at fair value. The aggregate settlement value of these units (based on the number of units outstanding and the average closing price of the common shares during the last five business days of the quarter ended September 30, 2024) was approximately $2.8 million and $2.8 million as of September 30, 2024 and December 31, 2023, respectively.

(a)Includes property operating expenses, real estate taxes and third-party management expense.

Net operating income (“NOI”) is a non-GAAP financial measure, which we define as total property revenue less property operating expenses, real estate taxes and third-party management expenses. Property operating expenses that are included in determining NOI consist of costs that are necessary and allocable to our operating properties such as utilities, property-level salaries, repairs and maintenance, property insurance and management fees. General and administrative expenses that are not reflected in NOI primarily consist of corporate-level salaries, amortization of share awards and professional fees that are incurred as part of corporate office management. NOI presented by the Company may not be comparable to NOI reported by other companies that define NOI differently. NOI is the primary measure that is used by the Company’s management to evaluate the operating performance of the Company’s real estate assets by segment. The Company believes NOI provides useful information to investors regarding the financial condition and results of operations because it reflects only those income and expense items that are incurred at the property level. While NOI is a relevant and widely used measure of operating performance of real estate investment trusts, it does not represent cash flow from operations or net income as defined by GAAP and should not be considered as an alternative to those measures in evaluating our liquidity or operating performance. NOI does not reflect interest expenses, real estate impairment losses, depreciation and amortization costs, capital expenditures and leasing costs. The Company believes that net income (loss), as defined by GAAP, is the most appropriate earnings measure. The following is a reconciliation of consolidated net income (loss), as defined by GAAP, to consolidated NOI, (in thousands):

14. COMMITMENTS AND CONTINGENCIES

Legal Proceedings

The Company is involved from time to time in litigation on various matters, including disputes with tenants, vendors and disputes arising out of agreements to purchase or sell properties. Given the nature of the Company’s business activities, these lawsuits are considered routine to the conduct of its business. The result of any particular lawsuit cannot be predicted, because of the very nature of litigation, the litigation process and its adversarial nature, and the jury system. The Company will establish reserves for specific legal proceedings when it determines that the likelihood of an unfavorable outcome is probable and when the amount of loss is reasonably estimable. The Company does not expect that the liabilities, if any, that may ultimately result from such legal actions will have a material adverse effect on the consolidated financial position, results of operations or cash flows of the Company.

Environmental

As an owner of real estate, the Company is subject to various environmental laws of federal, state, and local governments. The Company’s compliance with existing laws has not had a material adverse effect on its financial condition and results of operations, and the Company does not believe it will have a material adverse effect in the future. However, the Company cannot predict the impact of unforeseen environmental contingencies or new or changed laws or regulations on its current Properties or on properties that the Company may acquire.

Debt Guarantees and Equity Funding Commitments

As of September 30, 2024, the Company’s unconsolidated real estate ventures had aggregate indebtedness of $890.8 million. These loans are generally mortgage loans or secured construction loans, most of which are nonrecourse to the Company, except for customary recourse carve-outs. In addition, during construction undertaken by the unconsolidated real estate ventures, including the 3025 JFK Venture, the 3151 Market Street Venture, and the One Uptown Ventures, the Company has provided, and expects to continue to provide, cost overrun and completion guarantees, as well as customary environmental indemnities and guarantees of customary exceptions to nonrecourse provisions in loan agreements.

In the agreement with its partner in the 3025 JFK Venture, the Company agreed to provide cost overrun and completion guarantees for the project under development. With respect to the construction loan obtained by 3025 JFK Venture on July 23, 2021, the Company also provided a carry guarantee and limited payment guarantee up to 25% of the principal balance of the $186.7 million construction loan.

In the agreement with its partner in the 3151 Market Street Venture, the Company agreed to provide cost overrun and completion guaranties for the project under development. As of September 30, 2024, total estimated costs to develop 3151 Market Street are approximately $316.9 million and as of such date, the Company has fully funded its share of equity. However, the development budget for this project contemplated receipt of a construction loan of approximately $174.3 million, reflecting a 55% loan to value ratio and, as of the date of this Form 10-Q, no construction loan has been obtained and there can be no assurance that a loan will be obtained. In the event that costs are incurred before a construction loan has been obtained, the Company expects to fund such costs through its credit facilities and cash on hand.

With respect to the One Uptown Ventures, the Company has provided completion guarantees and environmental indemnities in favor of its partner. In addition, the Company has provided completion guarantees, environmental indemnities and guarantees of exceptions to nonrecourse loan provisions in favor of the lenders for the One Uptown Ventures. Moreover, the Company has provided, in favor of the lenders, carry guarantees and limited payment guarantees up to 30% and 15% of the principal balance of the $121.7 million (office) and $85.0 million (multifamily) construction loans, respectively.

The Company has agreed, pursuant to the leasehold mortgage loan to the New MAP Venture, to fund up to an additional $12 million for tenant and capital improvements pursuant to leases that the Company proposes, in its discretion, to enter into at the properties owned (through leasehold interests) by the New MAP Venture, which amounts, when funded, will accrue interest at 8.0% per annum.

The Company has agreed to contribute and has subsequently funded $23.0 million to the Commerce Square Venture in November 2024. See Note 4“Investment in Unconsolidated Real Estate Ventures,” for further information.

Impact of Natural Disasters and Casualty

The Company carries liability insurance to mitigate its exposure to certain losses, including those relating to property damage. The Company records the estimated amount of expected insurance proceeds for property damage and other losses incurred as an asset (typically a receivable from the insurer) and income up to the amount of the losses incurred when receipt of insurance proceeds is deemed probable. Any amount of insurance recovery in excess of the amount of the losses is considered a gain contingency and is not recorded until the proceeds are received.

Other Commitments or Contingencies

In connection with the Schuylkill Yards Project, the Company entered into a neighborhood engagement program and, as of September 30, 2024, had $5.6 million of future fixed contractual obligations. The Company also committed to fund additional contributions under the program. As of September 30, 2024, the Company estimates that these additional contributions, which are not fixed under the terms of agreement, will be $2.0 million.

The Company has committed to contribute $15.0 million to a venture capital fund that invests in early-stage life science companies. As of September 30, 2024, the Company had funded $2.5 million of the foregoing commitment.

The Company invests in its properties and regularly incurs capital expenditures in the ordinary course of business to maintain the properties. The Company believes that such expenditures enhance its competitiveness. The Company also enters into construction, utility and service contracts in the ordinary course of business which may extend beyond one year. These contracts typically provide for cancellation with insignificant or no cancellation penalties.
