Basis of Presentation Basis of Presentation
The accompanying consolidated financial statements are unaudited and include the accounts of Alexander’s and its consolidated subsidiaries. All adjustments (which include only normal recurring adjustments) necessary to present fairly the financial position, results of operations and changes in cash flows have been made. Certain information and footnote disclosures normally included in financial statements prepared in accordance with accounting principles generally accepted in the United States of America (“GAAP”) have been condensed or omitted. These consolidated financial statements have been prepared in accordance with the instructions to Form 10-Q of the Securities and Exchange Commission (“SEC”) and should be read in conjunction with the consolidated financial statements and notes thereto included in our Annual Report on Form 10-K for the year ended December 31, 2025, as filed with the SEC.
We have made estimates and assumptions that affect the reported amounts of assets and liabilities, disclosure of contingent assets and liabilities at the date of the consolidated financial statements and the reported amounts of revenues and expenses during the reporting periods. Actual results could differ from those estimates. The results of operations for the three and six months ended June 30, 2026 are not necessarily indicative of the operating results for the full year. Certain prior year balances have been reclassified in order to conform to the current period presentation.

Bloomberg L.P. (“Bloomberg”) leases approximately 952,000 square feet at our 731 Lexington Avenue property and accounted for revenue of $65,229,000 and $64,446,000 for the six months ended June 30, 2026 and 2025, respectively, representing approximately 60% and 61% of our rental revenues in each period, respectively. No other tenant accounted for more than 10% of our rental revenues. If we were to lose Bloomberg as a tenant, or if Bloomberg were to be unable to fulfill its obligations under its lease, it would adversely affect our results of operations and financial condition. In order to assist us in our continuing assessment of Bloomberg’s creditworthiness, we receive certain confidential financial information and metrics from Bloomberg. In addition, we access and evaluate financial information regarding Bloomberg from other private sources, as well as publicly available data.
In May 2024, Alexander’s and Bloomberg entered into an agreement to extend Bloomberg’s leases that were scheduled to expire in February 2029 for a term of eleven years to February 2040. In connection with the lease extension, Bloomberg was entitled to a $113,618,000 tenant fund which is accounted for as a lease incentive under GAAP. Accordingly, there was an initial deferred lease incentive asset of $113,618,000, which is amortized as a reduction to rental revenues over the remaining term of the lease, and a corresponding liability. These amounts are included in “Deferred leasing costs, net” and “Lease incentive liability,” on our consolidated balance sheets. On March 31, 2026, Alexander’s and Bloomberg entered into a lease amendment providing Bloomberg with a rent abatement of $56,809,000 for the period of April 1, 2026 to December 1, 2026, which reduces the tenant fund by a corresponding amount over that period from $113,618,000 to $56,809,000.
On June 26, 2026, we entered into a lease modification agreement with a 135,000 square foot tenant at our Rego Park shopping center providing options for us and the tenant to early terminate the lease in August 2026, subject to a payment of approximately $29,000,000 from the tenant. Simultaneously, we entered into a 15-year lease, plus renewal options, with Target for that space.

Management and Development Agreements
We pay Vornado an annual management fee equal to the sum of (i) $2,800,000, (ii) 2% of gross revenue from the Rego Park shopping center, (iii) $0.50 per square foot of the tenant-occupied office and retail space at 731 Lexington Avenue, and (iv) $399,000, escalating at 3% per annum, for managing the common area of 731 Lexington Avenue.

Leasing and Other Agreements
Vornado also provides us with leasing services for a fee of 3% of rent for the first ten years of a lease term, 2% of rent for the eleventh through the twentieth year of a lease term, and 1% of rent for the twenty-first through thirtieth year of a lease term, subject to the payment of rents by tenants. In the event third-party real estate brokers are used, the Company is responsible for any third-party lease commissions and Vornado’s fee is one-third of the applicable third-party lease commission.
Vornado is also entitled to a commission upon the sale of any of our assets equal to 3% of gross proceeds, as defined, for asset sales less than $50,000,000 and 1% of gross proceeds, as defined, for asset sales of $50,000,000 or more (the “Sales Commission Agreement”). Pursuant to the Sales Commission Agreement, we paid a $2,355,000 sales commission to Vornado in the second quarter of 2026 related to the sale of our Rego Park I property.
We also have agreements with Building Maintenance Services LLC, a wholly owned subsidiary of Vornado, to supervise (i) cleaning, engineering and security services at our 731 Lexington Avenue property and (ii) security services at our Rego Park shopping center and The Alexander apartment tower.

The retail portion of 731 Lexington Avenue is encumbered by a mortgage loan of $300,000,000 which matures in December 2035. The loan was initially split into (i) a $132,500,000 senior A-Note held by a wholly owned subsidiary of Alexander’s, which bears interest at a fixed rate of 7.00% and (ii) a $167,500,000 junior C-Note held by third party lenders, which accrues PIK interest at 4.55%. In addition, Alexander’s funds operating shortfalls, interest on the A-Note and capital for re-leasing at the property through a B-Note, which is junior to the A-Note and senior to the C-Note. The B-Note bears interest at a fixed rate of 13.50%, except for loan amounts above $65,000,000 used to pay interest on the A-Note, which will bear interest at a fixed rate of 7.00%. As of June 30, 2026, the B-Note balance is approximately $1,307,000.

All future net sales or refinancing proceeds will be distributed through the payment waterfall per the terms of the loan agreement. If such proceeds (or appraised value in such refinancing) are insufficient to cover the C-Note loan balance, any outstanding C-Note indebtedness that remains unpaid shall be forgiven. Since the debt balances related to the A-Note and B-Note are eliminated in consolidation, the balances presented as mortgages payable for this loan on our consolidated balance sheets are comprised of the principal balance of the C-Note and the PIK interest due upon maturity.

Stock-Based Compensation Stock-Based Compensation
We account for stock-based compensation in accordance with Accounting Standards Codification (“ASC”) Topic 718, Compensation – Stock Compensation (“ASC 718”). Our Board of Directors and stockholders approved the Alexander’s, Inc. 2026 Omnibus Stock Plan (the “2026 Plan”), effective as of May 21, 2026, which serves as the successor to our 2016 Omnibus Stock Plan (the “2016 Plan”) and provides for the issuance of incentive and non-qualified stock options, restricted stock, stock appreciation rights, deferred stock units (“DSUs”) and performance shares to the directors, officers and employees of the Company and Vornado. No additional awards will be made under the 2016 Plan, but the terms and conditions of any outstanding awards granted under the 2016 Plan will not be affected. Shares subject to an award that expires unexercised, or that are forfeited, terminated or canceled, in whole or in part, will again be available for grant under the 2026 Plan.
In May 2026, we granted each of the members of our Board of Directors 505 DSUs with a market value of $125,000 per grant. The grant date fair value of these awards was $93,750 per grant, or $656,000 in the aggregate, in accordance with ASC 718. The DSUs entitle the holders to receive shares of the Company’s common stock without payment of any consideration. The DSUs vested immediately and, accordingly, were expensed on the date of grant, but the shares of common stock underlying the DSUs are not deliverable to the grantee until the grantee is no longer serving on the Company’s Board of Directors or until a later date selected by the grantee. As of June 30, 2026, there were 3,535 DSUs outstanding and 496,465 shares were available for future grant under the 2026 Plan.

Fair Value Disclosures [Abstract]  
Fair Value Measurements Fair Value Measurements
Accounting Standards Codification (“ASC”) Topic 820, Fair Value Measurement (“ASC 820”) defines fair value and establishes a framework for measuring fair value. ASC 820 establishes a fair value hierarchy that prioritizes observable and unobservable inputs used to measure fair value into three levels: Level 1 – quoted prices (unadjusted) in active markets that are accessible at the measurement date for assets or liabilities that are highly liquid and are actively traded in secondary markets; Level 2 – observable prices that are based on inputs not quoted in active markets, but corroborated by market data; and Level 3 – unobservable inputs that are used when little or no market data is available. The fair value hierarchy gives the highest priority to Level 1 inputs and the lowest priority to Level 3 inputs. In determining fair value, we utilize valuation techniques that maximize the use of observable inputs and minimize the use of unobservable inputs to the extent possible as well as consider counterparty credit risk in our assessment of fair value.
Financial Assets and Liabilities Measured at Fair Value
Financial assets measured at fair value on our consolidated balance sheets consisted of an interest rate cap, which is presented in the tables below based on its level in the fair value hierarchy. There were no financial liabilities measured at fair value as of June 30, 2026 and December 31, 2025.

Interest Rate Derivatives
We recognize the fair value of all interest rate derivatives in “other assets” or “other liabilities” on our consolidated balance sheets and since our interest rate derivative has been designated as a cash flow hedge, changes in the fair value are recognized in other comprehensive income. The table below summarizes our interest rate derivative, which hedges the interest rate risk attributable to the variable rate debt noted as of June 30, 2026 and December 31, 2025, respectively.

Financial Assets and Liabilities not Measured at Fair Value
Financial assets and liabilities that are not measured at fair value on our consolidated balance sheets include cash equivalents and mortgages payable. Cash equivalents are carried at cost, which approximates fair value due to their short-term maturities and are classified as Level 1. The fair value of our mortgages payable is calculated by discounting the future contractual cash flows of these instruments using current risk-adjusted rates available to borrowers with similar credit ratings, which are provided by a third-party specialist, and is classified as Level 2. The table below summarizes the carrying amount and fair value of these financial instruments as of June 30, 2026 and December 31, 2025, respectively.

Insurance
We maintain general liability insurance with limits of $300,000,000 per occurrence and per property, which includes communicable disease coverage, and all-risk property and rental value insurance coverage with limits of $1.7 billion per occurrence, including coverage for acts of terrorism, with sub-limits for certain perils such as floods and earthquakes on each of our properties and excluding communicable disease coverage.
Fifty Ninth Street Insurance Company, LLC (“FNSIC”), our wholly owned consolidated subsidiary, acts as a direct insurer for coverage for acts of terrorism, including nuclear, biological, chemical and radiological (“NBCR”) acts, as defined by the Terrorism Risk Insurance Act of 2002, as amended to date and which has been extended through December 2027. Coverage for acts of terrorism (including NBCR acts) is up to $1.7 billion per occurrence and in the aggregate. Coverage for acts of terrorism (excluding NBCR acts) is fully reinsured by third party insurance companies and the Federal government with no exposure to FNSIC. For NBCR acts, FNSIC is responsible for a deductible of $348,000 and 20% of the balance of a covered loss, and the Federal government is responsible for the remaining 80% of a covered loss. We are ultimately responsible for any loss incurred by FNSIC.
We continue to monitor the state of the insurance market and the scope and costs of coverage for acts of terrorism or other events. However, we cannot anticipate what coverage will be available on commercially reasonable terms in the future. We are responsible for uninsured losses and for deductibles and losses in excess of our insurance coverage, which could be material.
Our loans contain customary covenants requiring us to maintain insurance. Although we believe that we have adequate insurance coverage for purposes of these agreements, we may not be able to obtain an equivalent amount of coverage at reasonable costs in the future. If lenders insist on greater coverage than we are able to obtain, it could adversely affect our ability to finance or refinance our properties.
Other
There are various legal actions brought against us from time-to-time in the ordinary course of business. In our opinion, the outcome of such pending matters in the aggregate will not have a material effect on our financial position, results of operations or cash flows.

We have determined that our properties, which are considered our operating segments, have similar economic characteristics and meet the criteria that permit these operating segments to be aggregated into one reportable segment (the leasing, management, development and redevelopment of properties in New York City). Net operating income (“NOI”) represents total revenues less operating expenses. The Company’s chief operating decision maker ("CODM") is its Chief Executive Officer, who considers NOI to be the financial measure of segment profit and loss for making decisions on how to allocate resources and assessing the performance of the reportable segment. Asset information by segment is not reported as the CODM does not use this measure to assess segment performance or to make resource allocation decisions.

Basis of Presentation
The accompanying consolidated financial statements are unaudited and include the accounts of Alexander’s and its consolidated subsidiaries. All adjustments (which include only normal recurring adjustments) necessary to present fairly the financial position, results of operations and changes in cash flows have been made. Certain information and footnote disclosures normally included in financial statements prepared in accordance with accounting principles generally accepted in the United States of America (“GAAP”) have been condensed or omitted. These consolidated financial statements have been prepared in accordance with the instructions to Form 10-Q of the Securities and Exchange Commission (“SEC”) and should be read in conjunction with the consolidated financial statements and notes thereto included in our Annual Report on Form 10-K for the year ended December 31, 2025, as filed with the SEC.
We have made estimates and assumptions that affect the reported amounts of assets and liabilities, disclosure of contingent assets and liabilities at the date of the consolidated financial statements and the reported amounts of revenues and expenses during the reporting periods. Actual results could differ from those estimates. The results of operations for the three and six months ended June 30, 2026 are not necessarily indicative of the operating results for the full year. Certain prior year balances have been reclassified in order to conform to the current period presentation.
Recently Issued Accounting Literature In November 2024, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2024-03, Income Statement - Reporting Comprehensive Income - Expense Disaggregation Disclosures (Subtopic 220-40): Disaggregation of Income Statement Expenses (“ASU 2024-03”), and in January 2025, the FASB issued ASU 2025-01, Income Statement - Reporting Comprehensive Income - Expense Disaggregation Disclosures (Subtopic 220-40): Clarifying the Effective Date (“ASU 2025-01”). ASU 2024-03 requires additional disclosure of the nature of expenses included in the income statement as well as disclosures about specific types of expenses included in the expense captions presented in the income statement. ASU 2024-03, as clarified by ASU 2025-01, is effective for fiscal years beginning after December 15, 2026, and interim periods within fiscal years beginning after December 15, 2027, with early adoption permitted. We are currently evaluating the impact of these standards on our consolidated financial statements.
Fair Value Measurements
Accounting Standards Codification (“ASC”) Topic 820, Fair Value Measurement (“ASC 820”) defines fair value and establishes a framework for measuring fair value. ASC 820 establishes a fair value hierarchy that prioritizes observable and unobservable inputs used to measure fair value into three levels: Level 1 – quoted prices (unadjusted) in active markets that are accessible at the measurement date for assets or liabilities that are highly liquid and are actively traded in secondary markets; Level 2 – observable prices that are based on inputs not quoted in active markets, but corroborated by market data; and Level 3 – unobservable inputs that are used when little or no market data is available. The fair value hierarchy gives the highest priority to Level 1 inputs and the lowest priority to Level 3 inputs. In determining fair value, we utilize valuation techniques that maximize the use of observable inputs and minimize the use of unobservable inputs to the extent possible as well as consider counterparty credit risk in our assessment of fair value.
Stock-Based Compensation We account for stock-based compensation in accordance with Accounting Standards Codification (“ASC”) Topic 718, Compensation – Stock Compensation (“ASC 718”). Our Board of Directors and stockholders approved the Alexander’s, Inc. 2026 Omnibus Stock Plan (the “2026 Plan”), effective as of May 21, 2026, which serves as the successor to our 2016 Omnibus Stock Plan (the “2016 Plan”) and provides for the issuance of incentive and non-qualified stock options, restricted stock, stock appreciation rights, deferred stock units (“DSUs”) and performance shares to the directors, officers and employees of the Company and Vornado. No additional awards will be made under the 2016 Plan, but the terms and conditions of any outstanding awards granted under the 2016 Plan will not be affected. Shares subject to an award that expires unexercised, or that are forfeited, terminated or canceled, in whole or in part, will again be available for grant under the 2026 Plan.
