Notes to Condensed Consolidated Financial Statements

(unaudited)

1. Description of Business and Organization

As used in these condensed consolidated financial statements, unless the context otherwise requires, “we,” “us,” “our,” and the “Company,” mean Empire State Realty OP, L.P. and its consolidated subsidiaries.

Empire State Realty OP, L.P. (the "Operating Partnership") is the entity through which Empire State Realty Trust, Inc. (NYSE: ESRT), a NYC-focused real estate investment trust ("REIT") that owns and operates a portfolio of modernized, amenitized, and well-located office, retail, and multifamily assets, conducts all of its business and owns (either directly or through subsidiaries) substantially all of its assets. ESRT’s flagship Empire State Building, the “World's Most Famous Building,” features its iconic Observatory that was declared the #1 Attraction in the World - and the #1 Attraction in the U.S. for the third consecutive year – in Tripadvisor’s 2024 Travelers’ Choice Awards: Best of the Best Things to Do. The Company is a recognized leader in energy efficiency and indoor environmental quality.

As of ~~June~~September 30, 2024, our portfolio was comprised of approximately 7.98 million rentable square feet of office space, 0.7 million rentable square feet of retail space and ~~727~~732 residential units. Our office portfolio included 10 properties (including three long-term ground leasehold interests). Nine of these office properties are located in midtown Manhattan and encompass approximately 7.6 million rentable square feet of office space and 0.5 million rentable square feet of retail space, including the Empire State Building. The remaining office property ~~encompasses approximately 0.3 million rentable square feet and~~ is located in Stamford, Connecticut, with immediate access to mass transportation. Additionally, we have entitled land adjacent to the Stamford office property that can support the development of either office or residential per local zoning. Our multifamily portfolio included ~~727~~732 residential units in New York City.

We were organized as a Delaware limited partnership on November 28, 2011, and commenced operations upon completion of the initial public offering of ESRT’s Class A common stock and related formation transactions on October 7, 2013 (the "IPO"). ESRT's Class A common stock, par value $0.01 per share, is listed on the New York Stock Exchange under the symbol "ESRT." ESRT, as the sole general partner in our Company, has responsibility and discretion in the management and control of our Company, and our limited partners, in such capacity, have no authority to transact business for, or participate in the management activities, of our Company. As of ~~June~~September 30, 2024, ESRT owned approximately 60.37% of our operating partnership units.

2. Summary of Significant Accounting Policies

There have been no material changes to the summary of significant accounting policies included in the "Summary of Significant Accounting Policies" section in our Annual Report on Form 10-K/A for the year ended December 31, 2023 (the “Annual Report”).

Basis of Quarterly Presentation and Principles of Consolidation

The accompanying unaudited condensed consolidated financial statements have been prepared in conformity with accounting principles generally accepted in the United States of America ("GAAP"), for interim financial information, and with the rules and regulations of the Securities and Exchange Commission (the "SEC"). Accordingly, certain information and footnote disclosures required by GAAP for complete financial statements have been condensed or omitted in accordance with such rules and regulations. In the opinion of management, all adjustments and eliminations (including intercompany balances and transactions), consisting of normal recurring adjustments, considered necessary for the fair presentation of the financial statements have been included.

The results of operations for the periods presented are not necessarily indicative of the results that may be expected for the corresponding full years. These financial statements should be read in conjunction with the financial statements and accompanying notes included in the financial statements for the year ended December 31, 2023 contained in our Annual Report. Our Observatory business is subject to tourism trends and the weather, and therefore does experience some seasonality. For the year ended December 31, 2023, approximately 17% of our annual Observatory revenue was realized in the first quarter, 26% was realized in the second quarter, 29% was realized in the third quarter, and 28% was realized in the fourth quarter. Our multifamily business experiences some seasonality based on general market trends in New York City – the winter months (November through January) are slower in terms of lease activity. We seek to mitigate this by staggering lease terms such that

lease expirations are matched with seasonal demand. We do not consider the balance of our business to be subject to material seasonal fluctuations.

We consolidate entities in which we have a controlling financial interest. In determining whether we have a controlling financial interest in a partially owned entity and the requirement to consolidate the accounts of that entity, we consider factors such as ownership interest, board representation, management representation, authority to make decisions, and contractual and substantive participating rights of the partners/members. For variable interest entities ("VIE"), we consolidate the entity if we are deemed to have a variable interest in the entity and through that interest we are deemed the primary beneficiary. The primary beneficiary of a VIE is the entity that has (i) the power to direct the activities that most significantly impact the entity's economic performance and (ii) the obligation to absorb losses of the VIE or the right to receive benefits from the VIE that could be significant to the VIE. The primary beneficiary is required to consolidate the VIE. WeAs of September 30, 2024, we had noa ~~VIEs~~variable asinterest in and are deemed to be the primary beneficiary of ~~June 30,~~the September 2024 ~~and~~acquisition of the North 6th Street Collection. We had no VIEs as of December 31, 2023.

We will assess the accounting treatment for each investment we may have in the future. This assessment will include a review of each entity’s organizational agreement to determine which party has what rights and whether those rights are protective or participating. For all VIEs, we will review such agreements in order to determine which party has the power to direct the activities that most significantly impact the entity’s economic performance and benefit. In situations where we or our partner could approve, among other things, the annual budget, or leases that cover more than a nominal amount of space relative to the total rentable space at each property, we would not consolidate the investment as we consider these to be substantive participation rights that result in shared power of the activities that would most significantly impact the performance and benefit of such joint venture investment.

A non-controlling interest in a consolidated subsidiary is defined as the portion of the equity (net assets) in a subsidiary not attributable, directly or indirectly, to a parent. Non-controlling interests are required to be presented as a separate component of equity in the condensed consolidated balance sheets and in the condensed consolidated statements of operations by requiring earnings and other comprehensive income to be attributed to controlling and non-controlling interests.

Accounting Estimates

The preparation of the condensed consolidated financial statements in accordance with GAAP requires management to use estimates and assumptions that in certain circumstances affect the reported amounts of assets and liabilities, the disclosure of contingent assets and liabilities, and the reported revenues and expenses. Significant items subject to such estimates and assumptions include allocation of the purchase price of acquired real estate properties among tangible and intangible assets, determination of the useful life of real estate properties and other long-lived assets, valuation and impairment analysis of commercial real estate properties, goodwill, right-of-use assets and other long-lived and indefinite-lived assets, estimate of tenant expense reimbursements, valuation of the allowance for doubtful accounts, and valuation of derivative instruments, ground lease liabilities, senior unsecured notes, mortgage notes payable, unsecured revolving credit and term loan facilities, and equity-based compensation. These estimates are prepared using management’s best judgment, after considering past, current, and expected events and economic conditions. Actual results could differ from those estimates.

In April 2024, we worked with the First Stamford Place mortgage lender to structure a consensual foreclosure. On May 22, 2024, a receiver was appointed and we ended our management of the property. In connection with this, we removed the related assets and liabilities from our condensed consolidated balance sheet ~~as of June 30, 2024~~ and recognized a gain ~~of $10.8 million that is reflected~~ in the condensed consolidated statements of operations of $1.3 million and $12.1 million for the three and ~~six~~nine months ended ~~June~~ September 30, 2024, respectively.

As of September 30, 2024 and December 31, 2023, we had goodwill of $491.5 million. Goodwill was allocated $227.5 million to the Observatory reportable segment and $264.0 million to the real estate reportable segment.

We performed our annual goodwill testing in October 2023, where we bypassed the optional qualitative goodwill impairment assessment and proceeded directly to a quantitative assessment of the Observatory reportable segment and engaged a third-party valuation consulting firm to perform the valuation process. The quantitative analysis used a combination of the discounted cash flow method (a form of the income approach) utilizing Level 3 unobservable inputs and the guideline company method (a form of the market approach). Significant assumptions under the former included revenue and cost projections, weighted average cost of capital, long-term growth rate and income tax considerations while the latter included guideline company enterprise values, revenue multiples, EBITDA multiples and control premium rates. Our methodology to review goodwill impairment, which included a significant amount of judgment and estimates, provided a reasonable basis to determine whether impairment had occurred. The quantitative analysis performed concluded the fair value of the reporting unit exceeds its carrying value. We also perform quarterly qualitative assessments and have not identified any events which would indicate, on a more likely than not basis, that the goodwill allocated to the reporting unit was impaired. Many of the factors employed in determining whether or not goodwill is impaired are outside of our control, and it is reasonably likely that assumptions and estimates will change in future periods. We will continue to assess the impairment of the Observatory reporting unit goodwill going forward.

Unsecured Revolving Credit and Term Loan Facilities

On March 8, 2024, through our Operating Partnership, we entered into a second amended and restated credit agreement with Bank of America, N.A., as administrative agent and the other lenders party thereto, that amends and restates the amended and restated credit agreement, dated August 29, 2017 which governs our senior unsecured revolving credit facility and term loan facility (collectively, the “BofA Credit Facilities”). The BofA Credit Facilities are comprised of a $620 million senior unsecured revolving credit facility (the “Revolving Credit Facility”) and a $95 million term loan facility (the “BofA Term Loan Facility”). We may request that the BofA Credit Facilities be increased through one or more increases in the Revolving Credit Facility or one or more increases in the BofA Term Loan Facility or the addition of new pari passu term loan tranches, for a maximum aggregate principal amount under the second amended and restated credit agreement not to exceed $1.5 billion.

The Revolving Credit Facility matures on March 8, 2029, inclusive of two six-month extension periods and replaced the existing revolving credit facility that was due to mature in March 2025. The BofA Term Loan Facility matures on March 8, 2029, inclusive of two twelve-month extension periods and replaced the existing term loan facility that was due to mature in March 2025. Initial interest rates on the BofA Credit Facilities, which may change based on our leverage levels, are SOFR plus a benchmark adjustment of 10.0 basis points ("adjusted SOFR") plus 130 basis points for any drawn portion of the Revolving Credit Facility and adjusted SOFR plus 150 basis points for the BofA Term Loan Facility. In addition, the BofA Credit Facilities have a sustainability-linked pricing mechanism that reduces the borrowing spread if certain benchmarks are achieved each year. As of ~~June~~September 30, 2024, we had $120.0 million borrowings drawn on the Revolving Credit Facility and $95.0 million under the BofA Term Loan Facility.

On March 13, 2024, through our Operating Partnership, we entered into a third amendment to our credit agreement dated March 19, 2020 with Wells Fargo Bank, National Association, as administrative agent, and the other lenders party thereto, which governs a senior unsecured term loan facility (the “Wells Term Loan Facility”). The Wells Term Loan Facility is in the original principal amount of $175.0 million and matures on December 31, 2026. The third amendment provides for, among other things, certain conforming changes to the BofA Credit Facilities agreement, including increases to the capitalization rate for certain of our properties. No other changes were made to the amount of the commitments, the maturity date of the outstanding loans or the covenants. We may request the Wells Term Loan Facility be increased through one or more increases or the addition of new pari passu term loan tranches, for a maximum aggregate principal amount not to exceed $225 million. As of ~~June~~September 30, 2024, our borrowings amounted to $175.0 million under the Wells Term Loan Facility.

The terms of both the BofA Credit Facilities and the Wells Term Loan Facility include customary covenants, including limitations on liens, investment, distributions, debt, fundamental changes, and transactions with affiliates and require certain customary financial reports.

7. Financial Instruments and Fair Values

Derivative Financial Instruments

We use derivative financial instruments primarily to manage interest rate risk and such derivatives are not considered speculative. These derivative instruments are typically in the form of interest rate swap and forward agreements, and the primary objective is to minimize interest rate risks associated with investing and financing activities. The counterparties of these arrangements are major financial institutions with which we may also have other financial relationships. We are exposed to credit risk in the event of non-performance by these counterparties; however, we currently do not anticipate that any of the counterparties will fail to meet their obligations.

We have agreements with our derivative counterparties that contain a provision where if we either default or are capable of being declared in default on any of our indebtedness, then we could also be declared in default on our derivative obligations. As of ~~June~~September 30, 2024, wethe ~~did~~fair ~~not~~value ~~have~~of derivatives in a net liability position, that includes accrued interest but excludes any adjustment for nonperformance risk, related to these agreements was $2.1 million. If we had breached any of these

As of June 30, 2024 and December 31, 2023, we had interest rate swaps and caps with an aggregate notional value of $585.8 million and $573.2 million, respectively. The notional value does not represent exposure to credit, interest rate or market risks. As of June 30, 2024, the fair value of our derivative instruments in an asset position amounted to $16.2 million, which is included in prepaid expenses and other assets on the condensed consolidated balance sheet. As of December 31, 2023, the fair value of our derivative instruments amounted to $11.8 million which is included in prepaid expenses and other assets, and ($0.1 million) which is included in accounts payable and accrued expenses on the condensed consolidated balance sheet. These interest rate swaps have been designated as cash flow hedges and hedge the variability in future cash flows associated with our existing variable-rate term loan facilities. Interest rate caps not designated as hedges are not speculative and are used to manage our exposure to interest rate movements, but do not meet the strict hedge accounting requirements.

As of June 30, 2024 and 2023, our cash flow hedges are deemed highly effective and a net unrealized gain (loss) of $2.2 million and $8.1 million for the three and six months ended June 30, 2024, respectively, and a net unrealized gain of $10.1

Fair Valuation

The estimated fair values at September 30, 2024 and December 31, 2023 were determined by management, using available market information and appropriate valuation methodologies. Considerable judgment is necessary to interpret market data and develop estimated fair value. Accordingly, the estimates presented herein are not necessarily indicative of the amounts we could realize on disposition of the financial instruments. The use of different market assumptions and/or estimation methodologies may have a material effect on the estimated fair value amounts.

The fair value of derivative instruments is determined using widely accepted valuation techniques, including discounted cash flow analysis on the expected cash flows of each derivative. Although the majority of the inputs used to value our derivatives fall within Level 2 of the fair value hierarchy, the credit valuation adjustments associated with our derivatives utilize Level 3 inputs, such as estimates of current credit spreads to evaluate the likelihood of default by ourselves and our counterparties. The impact of such credit valuation adjustments, determined based on the fair value of each individual contract, was not significant to the overall valuation. As a result, all our derivatives were classified as Level 2 of the fair value hierarchy.

The fair values of our mortgage notes payable, senior unsecured notes (Series A, B, C, D, E, F, G, H, I, J, and K), unsecured term loan facilities and unsecured revolving credit facility which are determined using Level 3 inputs are estimated by discounting the future cash flows using current interest rates at which similar borrowings could be made by us.

8. Leases

Lessor

17We lease various spaces to tenants over terms ranging from one to 30 years. Certain leases have termination options for a fee and/or renewal options. The leases provide for base monthly rentals and reimbursements for real estate taxes, escalations linked to the consumer price index or common area maintenance known as operating expense escalation. Operating expense reimbursements are reflected in our September 30, 2024 and 2023 condensed consolidated statements of operations as rental revenue.

Lessee

We determine if an arrangement is a lease at inception. Our operating lease agreements relate to three ground lease assets and are reflected in right-of-use assets of $28.3 million and lease liabilities of $28.3 million in our condensed consolidated balance sheets as of ~~June~~September 30, 2024. Right-of-use assets represent our right to use an underlying asset for the lease term and lease liabilities represent our obligation to make lease payments arising from the lease. Right-of-use assets and liabilities are recognized at the commencement date based on the present value of lease payments over the lease term. Variable lease payments are excluded from the right-of-use assets and lease liabilities and are recognized in the period in which the obligation for those payments is incurred.

The ground leases are due to expire between the years 2050 and 2077, inclusive of extension options, and have no variable payments or residual value guarantees. As our leases do not provide an implicit rate, we determined our incremental borrowing rate based on information available at the date of adoption of Accounting Standards Update No. 2016-02, Leases (Topic 842), in determining the present value of lease payments. The weighted average incremental borrowing rate used to calculate the right-of-use assets and lease liabilities as of ~~June~~September 30, 2024 was 4.5%. Rent expense for lease payments related to our operating leases is recognized on a straight-line basis over the non-cancellable term of the leases. The weighted average remaining lease term as of ~~June~~September 30, 2024 was 4645.07 years.

9. Commitments and Contingencies

Legal Proceedings

Except as described below, as of ~~June~~September 30, 2024, we were not involved in any material litigation, nor, to our knowledge, was any material litigation threatened against us or our properties, other than routine litigation arising in the ordinary course of business such as disputes with tenants. We believe that the costs and related liabilities, if any, which may result from such actions will not materially affect our condensed consolidated financial position, operating results or liquidity.

As previously disclosed, in October 2014, 12 former investors (the "Claimants") in Empire State Building Associates L.L.C. (“ESBA”), which, prior to the IPO, owned the fee title to the Empire State Building, filed an arbitration with the American Arbitration Association against Peter L. Malkin, Anthony E. Malkin, Thomas N. Keltner, Jr., and our subsidiary ESRT MH Holdings LLC, the former supervisor of ESBA, (the "Respondents"). The statement of claim (also filed later in federal court in New York for the expressed purpose of tolling the statute of limitations) alleged breach of fiduciary duty and related claims in connection with the IPO and formation transactions and sought monetary damages and declaratory relief. Claimants had opted out of a prior class action bringing similar claims that were settled with court approval. Respondents filed an answer and counterclaims. In March 2015, the federal court action was stayed on consent of all parties pending the arbitration. Arbitration hearings started in May 2016 and concluded in August 2018. On August 26, 2020, the arbitration panel issued an award that denied all Claimants’ claims with one exception, on which it awarded the Claimants approximately $1.2 million, inclusive of seven years of interest through October 2, 2020. This amount was recorded as an IPO litigation expense in the consolidated statements of operations for the year ended December 31, 2020.

Respondents believe that such award in favor of the Claimants is entirely without merit and sought to vacate that portion of the award. On July 31, 2023, the New York State court denied the Respondents’ petition to vacate in part and confirmed the award. On January 22, 2024, that court entered judgment in favor of the Claimants (save for one Claimant, whose petition to confirm is still pending in New York state court) in an amount of approximately $1.26 million, inclusive of interest. The Respondents believe those rulings are incorrect and have appealed them. In addition, certain of the Claimants in the federal court action brought to toll the statute of limitations and sought to pursue claims in that case against the Respondents. Respondents believe that any such claims are meritless. The magistrate judge assigned to the action has issued a Report and Recommendation rejecting the Claimants’ claims; the district judge will decide whether to adopt the Report and Recommendation.

Pursuant to indemnification agreements which were made with our directors, executive officers and chairman emeritus as part of our formation transactions, Anthony E. Malkin, Peter L. Malkin and Thomas N. Keltner, Jr. have defense and indemnity rights from us with respect to this arbitration.

Unfunded Capital Expenditures

At ~~June~~September 30, 2024, we estimate that we will incur approximately $~~111~~126.65 million of capital expenditures (including tenant improvements and leasing commissions) on our properties pursuant to existing lease agreements. We expect to fund these capital expenditures with operating cash flow, cash on hand and other borrowings. Future property acquisitions may require substantial capital investments for refurbishment and leasing costs. We expect that these financing requirements will be met in a similar fashion.

Concentration of Credit Risk

Financial instruments that subject us to credit risk consist primarily of cash and cash equivalents, restricted cash, short-term investments, tenant and other receivables and deferred rent receivables. At ~~June~~September 30, 2024, we held on deposit at various major financial institutions cash and cash equivalents and restricted cash balances in excess of amounts insured by the Federal Deposit Insurance Corporation.

major financial institutions cash and cash equivalents and restricted cash balances in excess of amounts insured by the Federal Deposit Insurance Corporation.

Asset Retirement Obligations

We are required to accrue costs that we are legally obligated to incur on retirement of our properties which result from acquisition, construction, development and/or normal operation of such properties. Retirement includes sale, abandonment or disposal of a property. Under that standard, a conditional asset retirement obligation represents a legal obligation to perform an asset retirement activity in which the timing and/or method of settlement is conditional on a future event that may or may not be within a company’s control and a liability for a conditional asset retirement obligation must be recorded if the fair value of the obligation can be reasonably estimated. Environmental site assessments and investigations have identified asbestos or asbestos-containing building materials in certain of our properties. As of ~~June~~September 30, 2024, management has no plans to remove or alter these properties in a manner that would trigger federal and other applicable regulations for asbestos removal, and accordingly, the obligations to remove the asbestos or asbestos-containing building materials from these properties have indeterminable settlement dates. As such, we are unable to reasonably estimate the fair value of the associated conditional asset retirement obligation. However ongoing asbestos abatement, maintenance programs and other required documentation are carried out as required and related costs are expensed as incurred.

Other Environmental Matters

Under various federal, state and/or local laws, ordinances and regulations, as a current or former owner or operator of real property, we may be liable for costs and damages resulting from the presence or release of hazardous substances, waste, or petroleum products at, on, in, under or from such property, including costs for investigation or remediation, natural resource damages, or third-party liability for personal injury or property damage. These laws often impose liability without regard to whether the owner or operator knew of, or was responsible for, the presence or release of such materials, and the liability may be joint and several. Some of our properties have been or may be impacted by contamination arising from current or prior uses of the property or adjacent properties for commercial, industrial or other purposes. Such contamination may arise from spills of petroleum or hazardous substances or releases from tanks used to store such materials. We also may be liable for the costs of remediating contamination at off-site disposal or treatment facilities when we arrange for disposal or treatment of hazardous substances at such facilities, regardless of whether we comply with environmental laws in doing so. The presence of contamination or the failure to remediate contamination on our properties may adversely affect our ability to attract and/or retain tenants, and our ability to develop or sell or borrow against those properties. In addition to potential liability for cleanup costs, private plaintiffs may bring claims for personal injury, property damage or for similar reasons. Environmental laws also may create liens on contaminated sites in favor of the government for damages and costs it incurs to address such contamination. Moreover, if contamination is discovered on our properties, environmental laws may impose restrictions on the manner in which that property may be used or how businesses may be operated on that property.

may create liens on contaminated sites in favor of the government for damages and costs it incurs to address such contamination. Moreover, if contamination is discovered on our properties, environmental laws may impose restrictions on the manner in which that property may be used or how businesses may be operated on that property.

Some of our properties are adjacent to or near other properties which are used for industrial or commercial purposes or have contained or currently contain underground storage tanks used to store petroleum products or other hazardous or toxic substances. Releases from these properties could impact our properties. In addition, some of our properties have previously been used by former owners or tenants for commercial or industrial activities, e.g., gas stations and dry cleaners, and a portion of the Metro Tower site is currently used for automobile parking and was formerly leased to a fueling facility that may release petroleum products or other hazardous or toxic substances at such properties or to surrounding properties. While certain properties contain or contained uses that could have or have impacted our properties, we are not aware of any liabilities related to environmental contamination that we believe will have a material adverse effect on our operations.

We have post-closing obligations related to the 69-97 and 103-107 Main Street, Westport, Connecticut properties that we sold in February 2023 to (i) close out a voluntary remediation program at 69-97 Main Street to address residual impacts of prior presence of underground storage tanks and (ii) comply with a consent order issued by the Connecticut Department of Environmental Protection to investigate soil conditions at 103-107 Main Street. We believe any expenses incurred to close out and comply with the remediation program and consent order, respectively, will be immaterial to the results of our operations.

In addition, our properties are subject to various federal, state and local environmental and health and safety laws and regulations. Noncompliance with these laws and regulations could subject us or our tenants to liability. These liabilities could affect a tenant’s ability to make rental payments to us. Moreover, changes in laws could increase the potential costs of compliance with such laws and regulations or increase liability for noncompliance. This may result in significant unanticipated expenditures. We sometimes require our tenants to comply with environmental and health and safety laws and regulations and to indemnify us for any related liabilities in our leases with them. But in the event of the bankruptcy or inability of any of our tenants to satisfy such obligations, we may be required to satisfy such obligations. We are not presently aware of any instances of material non-compliance with environmental or health and safety laws or regulations at our properties, and we believe that we and/or our tenants have all material permits and approvals necessary under current laws and regulations to operate our properties.

of material non-compliance with environmental or health and safety laws or regulations at our properties, and we believe that we and/or our tenants have all material permits and approvals necessary under current laws and regulations to operate our properties.

In addition, we may become subject to new compliance requirements and/or new costs or taxes associated with natural resource or energy usage and related emissions (such as a carbon tax), which could increase our operating costs. In particular, as the owner of large commercial buildings in New York City, we are subject to Local Law 97 passed by the New York City Council in April 2019, which for each such building establishes annual limits for greenhouse gas emissions, requires yearly emissions reports beginning in May 2025, and imposes penalties for emissions above such limits. Based upon our present understanding of the law and calculations related thereto, we expect to pay no fine on any building in our commercial portfolio in the 2024-2029 first period of enforcement.

As the owner or operator of real property, we may also incur liability based on various building conditions. For example, environmental site assessments and investigations have identified asbestos or asbestos-containing material ("ACM") in certain of our properties, and it is possible that other properties that we currently own or operate or those we acquire or operate in the future contain, may contain, or may have contained ACM. Environmental and health and safety laws require that ACM be properly managed and maintained and may impose fines or penalties on owners, operators or employers for non-compliance with those requirements. These requirements include special precautions, such as removal, abatement or air monitoring, if ACM would be disturbed during maintenance, redevelopment or demolition of a building, potentially resulting in substantial costs. In addition, we may be subject to liability for personal injury or property damage sustained as a result of releases of ACM into the environment. We are not presently aware of any material liabilities related to building conditions, including any instances of material non-compliance with asbestos requirements or any material liabilities related to asbestos.

Our properties may contain or develop harmful mold or suffer from other indoor air quality issues, which could lead to liability for adverse health effects or property damage or costs for remediation. When excessive moisture accumulates in buildings or on building materials, mold growth may occur, particularly if the moisture problem remains undiscovered or is not addressed over a period of time. Some molds may produce airborne toxins or irritants. Indoor air quality issues can also stem from inadequate ventilation, chemical contamination from indoor or outdoor sources, and other biological contaminants such as pollen, viruses and bacteria. Indoor exposure to airborne toxins or irritants above certain levels can be alleged to cause a variety of adverse health effects and symptoms, including allergic or other reactions. As a result, the presence of significant mold or other airborne contaminants at any of our properties could require us to undertake a costly remediation program to contain or remove the mold or other airborne contaminants from the affected property or increase indoor ventilation. In addition, the presence of significant mold or other airborne contaminants could expose us to liability from our tenants, employees of our ~~tenants or others if property damage or personal injury occurs. We are not presently aware of any material adverse indoor air quality issues at our properties.~~

As of June 30, 2024, with the exception of the Westport assets, management believes that there are no obligations related to environmental remediation other than maintaining the affected sites in conformity with the relevant authority’s mandates and filing the required documents. All such maintenance costs are expensed as incurred. However, we cannot be certain that we have identified all environmental liabilities at our properties, that all necessary remediation actions have been or will be undertaken at our properties or that we will be indemnified, in full or at all, in the event that such environmental liabilities arise.21

Insurance Coverage

We carry insurance coverage on our properties of types and in amounts with deductibles that we believe are in line with coverage customarily obtained by owners of similar properties.

10. Capital

As of ~~June~~September 30, 2024, there were ~~164~~165,~~483~~506,~~385~~874 shares of Class A common stock, ~~981~~980,~~779~~707 shares of Class B common stock and ~~108~~107,~~713~~664,~~642~~445 operating partnership units outstanding. The controlling interest of 60.37% is owned by ESRT. The other 39.73% non-controlling interest in the OP is diversified among various limited partners, some of whom include Company directors, senior management and employees. ESRT has two classes of common stock as a means to give its OP Unit holders voting rights in the public company that correspond to their economic interest in the combined entity. A one-time option was created at our formation transactions for any pre-IPO OP Unit holder to exchange one OP Unit out of every 50 OP Units they owned for one ESRT Class B share, and such ESRT Class B share carries 50 votes per share.

Stock and Publicly Traded Operating Partnership Unit Repurchase Program

ESRT's Board of Directors authorized the repurchase of up to $500.0 million of ESRT Class A common stock and our Series ES, Series 250 and Series 60 operating partnership units from January 1, 2024 through December 31, 2025. Under the program, ESRT may purchase ESRT Class A common stock and we may purchase our Series ES, Series 250 and Series 60 operating partnership units in accordance with applicable securities laws from time to time in the open market or in privately negotiated transactions. The timing, manner, price and amount of any repurchases will be determined by ESRT and us at our discretion and will be subject to stock price, availability, trading volume, general market conditions, and applicable securities laws. The authorization does not obligate ESRT or us to acquire any particular amount of securities, and the program may be suspended or discontinued at ESRT's and our discretion without prior notice. As of September 30, 2024, we had $500.0 million remaining of the authorized repurchase amount. There were no repurchases of equity securities during the three and nine months ended September 30, 2024.

Private Perpetual Preferred Units

As of ~~June~~September 30, 2024, there were 4,664,038 Series 2019 Preferred Units ("Series 2019 Preferred Units") and 1,560,360 Series 2014 Private Perpetual Preferred Units ("Series 2014 Preferred Units") outstanding. The Series 2019 Preferred Units have a liquidation preference of $13.52 per unit and are entitled to receive cumulative preferential annual cash distributions of $0.70 per unit payable in arrears on a quarterly basis. The Series 2014 Preferred Units which have a liquidation preference of $16.62 per unit and are entitled to receive cumulative preferential annual cash distributions of $0.60 per unit payable in arrears on a quarterly basis. Both series are not redeemable at the option of the holders and are redeemable at our option only in the case of specific defined events.

Incentive and Share-Based Compensation

On May 9, 2024, the Empire State Realty Trust, Inc. Empire State Realty OP, L.P. 2024 Equity Incentive Plan (the “2024 Plan”) was approved by our shareholders. The 2024 Plan provides for grants to directors, employees and consultants of ESRT and the Operating Partnership, including options, restricted stock, restricted stock units, stock appreciation rights, performance awards, dividend equivalents and other equity-based awards, and replaced the First Amended and Restated Empire State Realty Trust, Inc. and Empire State Realty OP, L.P. 2019 Equity Incentive Plan ("2019 Plan", and collectively with the 2024 Plan, the "Plans"). The shares of ESRT Class A common stock underlying any awards under the Plans that are forfeited, canceled or otherwise terminated, other than by exercise, will be added back to the shares of ESRT Class A common stock available for issuance under the 2024 Plan. Shares tendered or held back upon exercise of a stock option or settlement of an award under the Plans to cover the exercise price or tax withholding and shares subject to a stock appreciation right that are not issued in connection with the stock settlement of the stock appreciation right upon exercise thereof, will not be added back to the shares of ESRT Class A common stock available for issuance under the 2024 Plan. In addition, shares of ESRT Class A common stock repurchased on the open market will not be added back to the shares of ESRT Class A common stock available for issuance under the 2024 Plan.

An aggregate of 11.0 million shares of ESRT common stock was authorized for issuance under awards granted pursuant to the 2024 Plan, and as of ~~June~~September 30, 2024, 10.89 million shares of common stock remain available for future issuance.

Long-term incentive plan ("LTIP") units are a special class of partnership interests. Each LTIP unit awarded will be deemed equivalent to an award of one share of ESRT stock under the Plans, reducing the availability for other equity awards on a one-for-one basis. The vesting period for LTIP units, if any, will be determined at the time of issuance. Under the terms of the LTIP units, we will revalue for tax purposes its assets upon the occurrence of certain specified events, and any increase in valuation from the time of one such event to the next such event will be allocated first to the holders of LTIP units to equalize the capital accounts of such holders with the capital accounts of unitholders. Subject to any agreed upon exceptions, once vested and having achieved parity with unitholders, LTIP units are convertible into Series PR operating partnership units on a one-for-one basis.

LTIP units subject to time-based vesting, whether vested or not, receive the same per unit distributions as operating partnership units, which equal per share dividends (both regular and special) on our common stock. Market and performance-based LTIPs receive 10% of such distributions currently, unless and until such LTIP units are earned based on performance, at which time they will receive the accrued and unpaid 90% and will commence receiving 100% of such distributions thereafter.

22During the third quarter of 2024, we did not make any grants of LTIP units to employees or non-employee directors that are subject to performance-based vesting or time-based vesting.

based LTIPs receive 10% of such distributions currently, unless and until such LTIP units are earned based on performance, at which time they will receive the accrued and unpaid 90% and will commence receiving 100% of such distributions thereafter.

During the second quarter of 2024, we made grants of 27,473 LTIP units to an employee that are subject to performance-based vesting with a fair market value of $0.3 million and 164,112 LTIP units to our non-employee directors that are subject to time-based vesting with fair market values of $1.5 million.

Share-based compensation for time-based equity awards is measured at the fair value of the award on the date of grant and recognized as an expense on a straight-line basis over the shorter of (i) the stated vesting period, which is generally three, four or five years, or (ii) the period from the date of grant to the date the employee becomes retirement eligible, which may occur upon grant. An employee is retirement eligible when the employee attains the (i) age of 65 for awards granted in 2020 and after and age of 60 for awards granted before 2020 and (ii) the date on which the employee has first completed the requisite years of continuous service with us or our affiliates. Share-based compensation for market-based equity awards and performance-based equity awards is measured at the fair value of the award on the date of grant and recognized as an expense on a straight-line basis over three or four years. Additionally, for the performance-based equity awards, we assess, at each reporting period, whether it is probable that the performance conditions will be satisfied. We recognize expense respective to the number of awards we expect to vest at the conclusion of the measurement period. Changes in estimate are accounted for in the period of change through a cumulative catch-up adjustment. Any forfeitures of share-based compensation awards are recognized as they occur.

For the market-based LTIP units, the fair value of the awards was estimated using a Monte Carlo Simulation model and discounted for the restriction period during which the LTIP units cannot be redeemed or transferred and the uncertainty regarding if, and when, the book capital account of the LTIP units will equal that of the common units. Our stock price, along with the prices of the comparative indexes, is assumed to follow the Geometric Brownian Motion Process. Geometric Brownian Motion is a common assumption when modeling in financial markets, as it allows the modeled quantity (in this case the stock price) to vary randomly from its current value and take any value greater than zero. The volatilities of the returns on our stock price and the comparative indexes were estimated based on implied volatilities and historical volatilities using an appropriate look-back period. The expected growth rate of the stock prices over the performance period is determined with consideration of the risk-free rate as of the grant date. For LTIP unit awards that are time or performance based, the fair value of the awards was estimated based on the fair value of our stock at the grant date discounted for the restriction period during which the LTIP units cannot be redeemed or transferred and the uncertainty regarding if, and when, the book capital account of the LTIP units will equal that of the common units. For restricted stock awards, the fair value of the awards is based on the market price of ESRT stock at the grant date.

LTIP units and ESRT restricted stock issued during the six months ended June 30, 2024 were valued at $27.8 million. The weighted average per unit or share fair value was $7.81 for grants issued for the six months ended June 30, 2024. The fair value per unit or share granted in 2024 was estimated on the respective dates of grant using the following assumptions: an expected life from 2.0 to 5.3 years, a dividend rate of 1.6%, a risk-free interest rate from 4.4% to 5.1%, and an expected price volatility from 37.0% to 48.0%. No other stock options, dividend equivalents, or stock appreciation rights were issued during the six months ended June 30, 2024.

The time-based LTIPs and ESRT restricted stock awards are treated for accounting purposes as immediately vested upon the later of (i) the date the grantee attains the age of 60 or 65, as applicable, and (ii) the date on which grantee has first completed the requisite years of continuous service with our Company or its affiliates. For award agreements that qualify, we recognize noncash compensation expense on the grant date for the time-based awards and ratably over the vesting period for the market-based and performance-based awards, and accordingly, we recognized $1.7 million and $2.4 million for the three and six months ended June 30, 2024, respectively, and $1.0 million and $1.7 million for the three and six months ended June 30,

The time-based LTIPs and ESRT restricted stock awards are treated for accounting purposes as immediately vested upon the later of (i) the date the grantee attains the age of 60 or 65, as applicable, and (ii) the date on which grantee has first completed the requisite years of continuous service with our Company or its affiliates. For award agreements that qualify, we recognize noncash compensation expense on the grant date for the time-based awards and ratably over the vesting period for the market-based and performance-based awards, and accordingly, we recognized $1.6 million and $4.0 million for the three and nine months ended September 30, 2024, respectively, and $0.5 million and $2.2 million for the three and nine months ended September 30, 2023, respectively. Unrecognized compensation expense was $13.3 million at September 30, 2024, which will be recognized over a weighted average period of 2.3 years.

For the remainder of the LTIP unit and ESRT restricted stock awards, we recognized noncash compensation expense ratably over the vesting period, and accordingly, we recognized noncash compensation expense of $4.2 million and $12.4 million for the three and nine months ended September 30, 2024, respectively, and $4.5 million and $12.6 million for the three and nine months ended September 30, 2023, respectively. Unrecognized compensation expense was $23.6 million at September 30, 2024, which will be recognized over a weighted average period of 2.3 years.

Earnings Per Unit

Earnings per unit is calculated by dividing the net income attributable to common unitholders by the weighted average number of units outstanding during the respective period. Unvested share-based payment awards that contain non-forfeitable rights to dividends, whether paid or unpaid, are accounted for as participating securities. Share-based payment awards are included in the calculation of diluted income using the treasury stock method if dilutive.

Earnings per unit is computed as follows:

12. Segment Reporting

We have identified two reportable segments: (1) real estate and (2) Observatory. Our real estate segment includes all activities related to the ownership, management, operation, acquisition, redevelopment, repositioning and disposition of our traditional real estate assets. Our Observatory segment operates the 86th and 102nd floor observatories at the Empire State Building. These two lines of businesses are managed separately because each business requires different support infrastructures, provides different services and has dissimilar economic characteristics such as investments needed, stream of revenues and marketing strategies. We account for intersegment sales and rents as if the sales or rents were to third parties, that is, at current market prices.

The following tables provide components of segment net income for each segment ~~for the three and six months ended June 30, 2024 and 2023 (amounts in thousands)~~:

ITEM 2. MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

Unless the context otherwise requires or indicates, references in this section to “we,” “our,” and “us” refer to the Empire State Realty OP, L.P. and its consolidated subsidiaries. This Management’s Discussion and Analysis provides a comparison of our performance for the three and ~~six~~nine month periods ended ~~June~~September 30, 2024 with the corresponding three and ~~six~~nine month periods ended ~~June~~September 30, 2023 and reviews our financial position as of ~~June~~September 30, 2024. The following discussion related to our consolidated financial statements should be read in conjunction with the financial statements and the notes thereto appearing elsewhere in this Quarterly Report on Form 10-Q and in our Annual Report on Form 10-K and Form 10-K/A.

FORWARD-LOOKING STATEMENTS

This Quarterly Report on Form 10-Q contains forward-looking statements within the meaning of Section 27A of the Securities Act of 1933, as amended (the “Securities Act"), and Section 21E of the Securities Exchange Act of 1934, as amended (the “Exchange Act”). We intend these forward-looking statements to be covered by the safe harbor provisions for forward-looking statements contained in the Private Securities Litigation Reform Act of 1995 and are including this statement for purposes of complying with those safe harbor provisions. You can identify forward-looking statements by the use of forward-looking terminology such as “aims," "anticipates," "approximately," "believes," "contemplates," "continues," "estimates," "expects," "forecasts," "hope," "intends," "may," "plans," "seeks," "should," "thinks," "will," "would" or the negative of these words and phrases or similar words or phrases. In particular, statements pertaining to ESRT's capital resources, portfolio performance, dividend policy and results of operations contain forward-looking statements. Likewise, all of our statements regarding anticipated growth in our portfolio from operations, acquisitions and anticipated market conditions, demographics and results of operations are forward-looking statements.

Forward-looking statements are subject to substantial risks and uncertainties, many of which are difficult to predict and are generally beyond our control, and you should not rely on them as predictions of future events. Forward-looking statements depend on assumptions, data or methods which may be incorrect or imprecise, and we may not be able to realize them. We do not guarantee that the transactions and events described will happen as described (or that they will happen at all).

Many important factors could cause actual results, performance, achievements, and future events to differ materially from those set forth, implied, anticipated, expected, projected, assumed or contemplated in the forward-looking statements, including, among other things: (i) economic, market, political and social impact of, and uncertainty relating to, any catastrophic events, including pandemics, epidemics or other outbreaks of disease, climate-related risks such as natural disasters and extreme weather events, terrorism and other armed hostilities, as well as cybersecurity threats and technology disruptions; (ii) a failure of conditions or performance regarding any event or transaction described herein; (iii) resolution of legal proceedings involving the Company; (iv) reduced demand for office, multifamily or retail space, including as a result of the changes in the use of office space and remote work; (v) changes in our business strategy; (vi) a decline in Observatory visitors due to changes in domestic or international tourism, including due to health crises, geopolitical events, currency exchange rates, and/or competition from other observatories; (vii) defaults on, early terminations of, or non-renewal of, leases by tenants; (viii) increases in the Company’s borrowing costs as a result of changes in interest rates and other factors; (ix) declining real estate valuations and impairment charges; (x) termination of our ground leases; (xi) limitations on our ability to pay down, refinance, restructure or extend our indebtedness or borrow additional funds; (xii) decreased rental rates or increased vacancy rates; (xiii) difficulties in executing capital projects or development projects successfully or on the anticipated timeline or budget; (xiv) difficulties in identifying and completing acquisitions; (xv) impact of changes in governmental regulations, tax laws and rates and similar matters; (xvi) our failure to qualify as a REIT; (xvii) incurrence of taxable capital gain on disposition of an asset due to failure of compliance with a 1031 exchange program; (xviii) our disclosure controls and internal control over financial reporting, including any material weakness; and (xix) failure to achieve sustainability metrics and goals, including as a result of tenant collaboration, and impact of governmental regulation on our sustainability efforts. For a further discussion of these and other factors that could impact the Company's future results, performance, or transactions, see the section entitled “Risk Factors” in the Company’s Annual Report for the year ended December 31, 2023 and our quarterly report for the quarter ended June 30, 2024, and other risks described in documents subsequently filed by the Company from time to time with the SEC.

While forward-looking statements reflect the Company's good faith beliefs, they do not guarantee future performance. Any forward-looking statement speaks only as of the date on which it was made, and we assume no obligation to update or revise publicly any forward-looking statement to reflect changes in underlying assumptions or factors, new information, data or methods, future events, or other changes after the date of this Quarterly Report on Form 10-Q, except as required by applicable law. Prospective investors should not place undue reliance on any forward-looking statements, which are based only on information currently available to the Company (or to third parties making the forward-looking statements).

Real Estate Segment

Rental Revenue

Liquidity and Capital Resources

Liquidity is a measure of our ability to meet potential cash requirements, including ongoing commitments to repay borrowings, fund and maintain our assets and operations, including lease-up costs, fund our redevelopment and repositioning programs, acquire properties, make distributions to our securityholders and fulfill other general business needs. Based on the historical experience of our management and our business strategy, in the foreseeable future we anticipate we will generate positive cash flows from operations. In order for ESRT to qualify as a REIT, ESRT is required under the Internal Revenue Code of 1986 to distribute to its stockholders, on an annual basis, at least 90% of its REIT taxable income, determined without regard to the deduction for dividends paid and excluding net capital gains. We expect to make quarterly distributions, as required, to our securityholders.

While we may be able to anticipate and plan for certain liquidity needs, there may be unexpected increases in uses of cash that are beyond our control and which would affect our financial condition and results of operations. For example, we may be required to comply with new laws or regulations that cause us to incur unanticipated capital expenditures for our properties, thereby increasing our liquidity needs. Even if there are no material changes to our anticipated liquidity requirements, our sources of liquidity may be fewer than, and the funds available from such sources may be less than, anticipated or needed. Our primary sources of liquidity will generally consist of cash on hand, cash generated from our operating activities, debt issuances and unused borrowing capacity under our unsecured revolving credit facility. We expect to meet our short-term liquidity requirements, including distributions, operating expenses, working capital, debt service, and capital expenditures from cash flows from operations, cash on hand, debt issuances, and available borrowing capacity under our unsecured revolving credit facility. The availability of these borrowings is subject to the conditions set forth in the applicable loan agreements. We expect to meet our long-term capital requirements, including acquisitions, redevelopments and capital expenditures through our cash flows from operations, cash on hand, our unsecured revolving credit facility, mortgage financings, debt issuances, common and/or preferred equity issuances and asset sales. Our properties require periodic investments of capital for individual lease related tenant improvement allowances, general capital improvements and costs associated with capital expenditures. Our overall leverage will depend on our mix of investments and the cost of leverage. ESRT's charter does not restrict the amount of leverage that we may use.

33At September 30, 2024, we had $421.9 million available in cash and cash equivalents, and $500.0 million available under our unsecured revolving credit facility.

On February 1, 2023, we closed on the sale of 69-97 and 103-107 Main Street in Westport, Connecticut at a gross asset valuation of $40.0 million.

On April 5, 2023, we closed on the sale of 500 Mamaroneck Avenue in Harrison, New York at a gross asset valuation of $53.0 million.

On September 14, 2023, we closed on the acquisition of a Williamsburg retail property located on the corner of North 6th Street and Wythe Avenue in Brooklyn, New York, for a purchase price of $26.4 million.

On March 28, 2024, we executed a buyout of ~~our~~the ~~partner's~~ 10% non-controlling interest in two of our multifamily properties located at 561 10th Avenue and 345 East 94th Street in Manhattan for $14.2 million in cash and the assumption of $18.0 million of in-place debt and now own 100% of the ownership interests in these assets.

In September 2024, we entered into an agreement to acquire an additional retail asset on North 6th Street in Williamsburg, Brooklyn for approximately $30.0 million. This acquisition is subject to customary closing conditions. The acquisition is anticipated to close in mid-2025.

Unsecured Revolving Credit and Term Loan Facilities

In March 2024, we closed on the BofA Credit Facilities, a $715 million, five-year unsecured credit agreement which consists of the $620.0 million Revolving Credit Facility and the $95.0 million BofA Term Loan Facility. The Revolving Credit Facility matures on March 8, 2029, inclusive of two six-month extension periods and replaced the existing revolving credit facility that was due to mature in March 2025. The BofA Term Loan Facility matures on March 8, 2029, inclusive of two twelve-month extension periods and replaced the existing term loan facility that ~~matures~~was due to mature in March 2025. Initial interest rates on the ~~new~~BofA ~~facility~~Credit Facilities, which may change based on our leverage levels, are adjusted SOFR plus 130 basis points for any drawn portion of the Revolving Credit Facility and adjusted SOFR plus 150 basis points for the BofA Term Loan Facility. In addition, the BofA Credit Facilities have a sustainability-linked pricing mechanism that reduces the borrowing spread if certain benchmarks are achieved each year. See "Financial Statements - Note 5 Debt" for a summary of our unsecured revolving credit and term loan facilities.

Financial Covenants

As of ~~June~~September 30, 2024, we were in compliance with the following financial covenants:

Mortgage Debt

As of ~~June~~September 30, 2024, mortgage notes payable, net, amounted to $~~700~~705.36 million. ~~After~~We ~~the~~have ~~refinancing~~no ~~discussed below, the next~~ mortgage debt maturity isuntil April 2026.

In April 2024, we worked with the First Stamford Place mortgage lender to structure a consensual foreclosure. In May 2024, the First Stamford Place property was placed in receivership and accordingly, we reclassified the related debt and applicable accrued interest to debt associated with property under receivership and accrued interest associated with property in receivership, respectively, in our condensed consolidated balance sheet. As of September 30, 2024, this debt consists of a $164 million mortgage loan bearing interest at 4.09% and a $11.9 million loan bearing interest at 6.25%. In connection with this we recorded a contract asset which represents the amount of obligation we expect to be released upon the final resolution of the foreclosure process on the First Stamford Place property.

34In July 2024, we executed an agreement for the refinance of the mortgage for the Metro Center property that was due to mature in November 2024. Beginning in November 2024, the new loan balance of $71.6 million will be interest-only at the same interest rate of 3.59%, with a maturity of November 2029, inclusive of a one-year extension option.

Stamford Place property was placed in receivership and accordingly, we reclassified the related debt and applicable accrued interest to debt associated with property under receivership and accrued interest associated with property in receivership, respectively, in our condensed consolidated balance sheet as of June 30, 2024. In connection with this we recorded a contract asset which represents our right to debt extinguishment once the foreclosure process on the First Stamford Place property is completed.

Subsequent to quarter-end, in July 2024, we executed an agreement for the refinance of the mortgage for the Metro Center property that was due to mature in November 2024. Beginning November 2024, the new loan balance of $71.6 million will be interest-only at the same interest rate of 3.59%, with a maturity of November 2029, inclusive of a one-year extension option.

Leverage Policies

We expect to employ leverage in our capital structure in amounts determined from time to time by ESRT's Board of Directors. Although ESRT's Board of Directors has not adopted a policy that limits the total amount of indebtedness that we may incur, we anticipate that ESRT's Board of Directors will consider a number of factors in evaluating our level of indebtedness from time to time, as well as the amount of such indebtedness that will be either fixed or floating rate. ESRT's charter and bylaws do not limit the amount or percentage of indebtedness that we may incur nor do they restrict the form in which our indebtedness will be taken (including, but not limited to, recourse or non-recourse debt and cross-collateralized debt). Our overall leverage will depend on our mix of investments and the cost of leverage. ESRT's Board of Directors may from time to time modify our leverage policies in light of the then-current economic conditions, relative costs of debt and equity capital, market values of our properties, general market conditions for debt and equity securities, fluctuations in the market price of ESRT's common stock and our traded OP units, growth and acquisition opportunities and other factors.

Capital expenditures are considered part of both our short-term and long-term liquidity requirements. We intend to fund capital improvements through a combination of operating cash flow, cash on hand and borrowings.

Off-Balance Sheet Arrangements

As of ~~June~~September 30, 2024, we did not have any off-balance sheet arrangements.

Distribution Policy

We intend to distribute our net taxable income to our securityholders in a manner intended to satisfy REIT distribution requirements and to avoid U.S. federal income tax liability.

Before we pay any distribution, whether for U.S. federal income tax purposes or otherwise, we must first meet both our operating requirements and obligations to make payments of principal and interest, if any. However, under some circumstances, we may be required to use cash reserves, incur debt or liquidate assets at rates or times that we regard as unfavorable or make a taxable distribution of our shares in order to satisfy REIT distribution requirements.

Distribution to Equity Holders

Distributions and dividends amounting to $2131.28 million and $2030.38 million have been made to equity holders for the ~~six~~nine months ended ~~June~~September 30, 2024 and 2023, respectively.

Stock and Publicly Traded Operating Partnership Unit Repurchase Program

ESRT's Board of Directors authorized the repurchase of up to $500.0 million of ESRT Class A common stock and our Series ES, Series 250 and Series 60 operating partnership units from January 1, 2024 through December 31, 2025. Under the program, ESRT may purchase ESRT Class A common stock and we may purchase our Series ES, Series 250 and Series 60 operating partnership units in accordance with applicable securities laws from time to time in the open market or in privately negotiated transactions. The timing, manner, price and amount of any repurchases will be determined by ESRT and us at our discretion and will be subject to stock price, availability, trading volume, general market conditions, and applicable securities laws. The authorization does not obligate ESRT or us to acquire any particular amount of securities, and the program may be suspended or discontinued at ESRT's and our discretion without prior notice. As of ~~June~~September 30, 2024, we had $500 .0 million remaining of the authorized repurchase amount. There were no repurchases of equity securities during the three and ~~six~~nine months ended ~~June~~September 30, 2024. See "Financial Statements - Note 10. Capital."

Cash Flows

Comparison of ~~Six~~Nine Months Ended ~~June~~September 30, 2024 to the ~~Six~~Nine Months Ended ~~June~~September 30, 2023

Net cash. Cash and cash equivalents and restricted cash were $~~576~~469.59 million and $~~395~~421.80 million, respectively, as of ~~June~~September 30, 2024 and 2023. The increase was primarily the result of the following changes in cash flows:

Operating activities. Net cash provided by operating activities increased by $214.18 million to $~~108~~210.19 million primarily due to an increase in revenue including decreases in rent concessions and increase in lease termination fees. These increases are partially offset by decreases in working capital, particularly a reduction in security deposits as more tenants replaced cash deposits with letters of credit in the current period, as well as the derecognition of First Stamford Place in May 2024.

Investing activities. Net cash used in investing activities increased by $~~140~~279.41 million to $~~127~~318.75 million primarily due to ~~there~~the ~~being~~$143.4 million noacquisition ~~proceeds~~of ~~from~~a ~~the~~portfolio ~~disposition~~ of ~~property~~retail properties on North 6th Street in ~~the~~Williamsburg ~~current~~in ~~period~~September ~~and~~2024, compared to the $26.9 million acquisition of retail ~~non-controlling~~properties ~~interests~~on North 6th Street in ~~other~~Williamsburg ~~partnerships~~in September 2023.

Acquisitions and Dispositions"). Net cash used in investing activities also increased due to a $42.5 million increase in capital expenditures and redevelopment in the nine months ended September 30, 2024 compared to the nine months ended September 30, 2023.

Financing activities. Net cash provided by financing activities increased by $~~226~~221.70 million to $~~189~~170.26 million primarily due to proceeds from a private placement of senior unsecured notes in the current period. See "Financial Statements - Note 5. Debt."

Net Operating Income

Net operating income ("NOI") is a non-GAAP financial measure of performance. NOI is used by our management to evaluate and compare the performance of our properties and to determine trends in earnings and to compute the fair value of our properties as it is not affected by: (i) the cost of funds of the property owner, (ii) the impact of depreciation and amortization expenses as well as gains or losses from the sale of operating real estate assets that are included in net income computed in accordance with GAAP, (iii) acquisition expenses, loss on early extinguishment of debt, impairment charges and loss from derivative financial instruments, or (iv) general and administrative expenses and other gains and losses that are specific to the property owner. The cost of funds is eliminated from NOI because it is specific to the particular financing capabilities and constraints of the owner. The cost of funds is eliminated because it is dependent on historical interest rates and other costs of capital as well as past decisions made by us regarding the appropriate mix of capital which may have changed or may change in the future. Depreciation and amortization expenses as well as gains or losses from the sale of operating real estate assets are eliminated because they may not accurately represent the actual change in value in our office or retail properties that result from use of the properties or changes in market conditions. While certain aspects of real property do decline in value over time in a manner that is reasonably captured by depreciation and amortization, the value of the properties as a whole have historically increased or decreased as a result of changes in overall economic conditions instead of from actual use of the property or the passage of time. Gains and losses from the sale of real property vary from property to property and are affected by market conditions at the time of sale which will usually change from period to period. These gains and losses can create distortions when comparing one period to another or when comparing our operating results to the operating results of other real estate companies that have not made similarly-timed purchases or sales. We believe that eliminating these costs from net income is useful to investors because the resulting measure captures the actual revenue generated and actual expenses incurred in operating our properties as well as trends in occupancy rates, rental rates and operating costs.

We believe that eliminating these costs from net income is useful to investors because the resulting measure captures the actual revenue generated and actual expenses incurred in operating our properties as well as trends in occupancy rates, rental rates and operating costs.

However, the usefulness of NOI is limited because it excludes general and administrative costs, interest expense, depreciation and amortization expense and gains or losses from the sale of properties, and other gains and losses as stipulated by GAAP, the level of capital expenditures and leasing costs necessary to maintain the operating performance of our properties, all of which are significant economic costs. NOI may fail to capture significant trends in these components of net income which further limits its usefulness.

NOI is a measure of the operating performance of our properties but does not measure our performance as a whole. NOI is therefore not a substitute for net income as computed in accordance with GAAP. This measure should be analyzed in conjunction with net income computed in accordance with GAAP and discussions elsewhere in this Management’s Discussion and Analysis of Financial Condition and Results of Operations regarding the components of net income that are eliminated in the calculation of NOI. Other companies may use different methods for calculating NOI or similarly titled measures and, accordingly, our NOI may not be comparable to similarly titled measures reported by other companies that do not define the measure exactly as we do.

The following table presents a reconciliation of our net income, the most directly comparable GAAP measure, to NOI ~~for the periods presented (amounts in thousands)~~:

Funds from Operations ("FFO")

We present below a discussion of FFO. We compute FFO in accordance with the “White Paper” on FFO published by the National Association of Real Estate Investment Trusts, or NAREIT, which defines FFO as net income (loss) (determined in accordance with GAAP), excluding impairment write-off of investments in depreciable real estate and investments in in-substance real estate investments, gains or losses from debt restructurings and sales of depreciable operating properties, plus real estate-related depreciation and amortization (excluding amortization of deferred financing costs), less distributions to non-controlling interests and gains/losses from discontinued operations and after adjustments for unconsolidated partnerships and joint ventures. FFO is a widely recognized non-GAAP financial measure for REITs that we believe, when considered with financial statements determined in accordance with GAAP, is useful to investors in understanding financial performance and providing a relevant basis for comparison among REITs. In addition, we believe FFO is useful to investors as it captures features particular to real estate performance by recognizing that real estate has generally appreciated over time or maintains residual value to a much greater extent than do other depreciable assets. Investors should review FFO, along with GAAP net income, when trying to understand an equity REIT’s operating performance. We present FFO because we consider it an important supplemental measure of our operating performance and believe that it is frequently used by securities analysts, investors and other interested parties in the evaluation of REITs. However, because FFO excludes depreciation and amortization and captures neither the changes in the value of our properties that result from use or market conditions nor the level of capital expenditures and leasing commissions necessary to maintain the operating performance of our properties, all of which have real economic effect and could materially impact our results of operations, the utility of FFO as a measure of performance is limited. There can be no assurance that FFO presented by us is comparable to similarly titled measures of other REITs. FFO does not represent cash generated from operating activities and should not be considered as an alternative to net income (loss) determined in accordance with GAAP or to cash flow from operating activities determined in accordance with GAAP. FFO is not indicative of cash available to fund ongoing cash needs, including the ability to make cash distributions. Although FFO is a measure used for comparability in assessing the performance of REITs, as the NAREIT White Paper only provides guidelines for computing FFO, the computation of FFO may vary from one company to another.

Modified Funds From Operations ("Modified FFO")

Modified FFO adds back an adjustment for any above or below-market ground lease amortization to traditionally defined FFO. We believe this a useful supplemental measure in evaluating our operating performance due to the non-cash accounting treatment under GAAP, which stems from the third quarter 2014 acquisition of two option properties following our formation transactions as they carry significantly below market ground leases, the amortization of which is material to our overall results. We present Modified FFO because we believe it is an important supplemental measure of our operating performance in that it adds back the non-cash amortization of below-market ground leases. There can be no assurance that Modified FFO presented by us is comparable to similarly titled measures of other REITs. Modified FFO does not represent cash generated from operating activities and should not be considered as an alternative to net income (loss) determined in

from debt restructurings and sales of depreciable operating properties, plus real estate-related depreciation and amortization (excluding amortization of deferred financing costs), less distributions to non-controlling interests and gains/losses from discontinued operations and after adjustments for unconsolidated partnerships and joint ventures.

Although FFO is a measure used for comparability in assessing the performance of REITs, as the NAREIT White Paper only provides guidelines for computing FFO, the computation of FFO may vary from one company to another.

Core Funds From Operations

Core FFO adds back to Modified FFO the following items: Interest expense associated with property in receivership and loss on early extinguishment of debt. The Company believes Core FFO is an important supplemental measure of its operating performance because it excludes non-recurring items. There can be no assurance that Core FFO presented by the Company is comparable to similarly titled measures of other REITs. Core FFO does not represent cash generated from operating activities and should not be considered as an alternative to net income (loss) determined in accordance with GAAP or to cash flow from operating activities determined in accordance with GAAP. Core FFO is not indicative of cash available to fund ongoing cash needs, including the ability to make cash distributions. In future periods, we may also exclude other items from Core FFO that we believe may help investors compare our results.

Factors That May Influence Future Results of Operations

Leasing

Due to the relatively small number of leases that are signed in any particular quarter, one or more larger leases may have a disproportionately positive or negative impact on average rent, tenant improvement and leasing commission costs for that period. As a result, we believe it is more appropriate when analyzing trends in average rent and tenant improvement and leasing commission costs to review activity over multiple quarters or years. Tenant improvement costs include expenditures for general improvements occurring concurrently with, but that are not directly related to, the cost of installing a new tenant. Leasing commission costs are similarly subject to significant fluctuations depending upon the length of leases being signed and the mix of tenants from quarter to quarter.

As of ~~June~~September 30, 2024, there were approximately 0.6 million rentable square feet of space in our portfolio available to lease (excluding leases signed but not yet commenced) representing 7.40% of the net rentable square footage of the properties in our commercial portfolio. In addition, leases representing 32.96% and 6.53% of net rentable square footage of the properties in our commercial portfolio will expire in 2024 and in 2025, respectively. These leases are expected to represent approximately 32.53% and 76.59%, respectively, of our annualized rent for such periods. Our revenues and results of operations can be impacted by expiring leases that are not renewed or re-leased or that are renewed or re-leased at base rental rates equal to, above or below the current average base rental rates. Further, our revenues and results of operations can also be affected by downtime after space is vacated and the costs we incur to re-lease available space, including payment of leasing commissions, redevelopments and build-to-suit remodeling that may not be borne by the tenant.

Observatory Operations

For the ~~six~~nine months ended ~~June~~September 30, 2024, the Observatory hosted 1,~~133~~860,000 visitors, compared to 1,~~108~~852,000 visitors for the ~~six~~nine months ended ~~June~~September 30, 2023, an increase of 20.4%. Observatory revenue for the ~~six~~nine months ended ~~June~~September 30, 2024 was $5898.71 million, a 65% increase from $93.1 million for the nine months ended September 30, 2023. The Observatory revenue increase was driven by higher visitation levels and ticket prices in 2024.

$55.6 million for the six months ended June 30, 2023. The Observatory revenue increase was driven by higher visitation levels and ticket prices in 2024.

Observatory revenues and admissions are dependent upon the following: (i) the number of tourists (domestic and international) who come to New York City and visit the Observatory, as well as any related tourism trends; (ii) the prices per admission that can be charged; (iii) seasonal trends affecting the number of visitors to the Observatory; (iv) competition, in particular from other new and existing observatories; and (v) weather trends.

Outlook

Year to date in 2024, ESRT has benefited from solid leasing activity and Observatory performance.

We believe the global economy, including the real estate sector, currently navigates an environment of uncertainty around inflation, higher interest rates, reduced availability of commercial real estate loans, questions on the direction of capital markets, risk of recession and geopolitical unrest. In particular, there have been concerns about the softening of the office real estate market in particular, amidst refinancing challenges of existing low interest rate loans and associated reduced new loan availability and increased costs of loans and related increased expectations of equity returns, coupled with the gradual pace of return-to-office and its impact on the physical utilization of space and asset valuations. Additionally, the risk of a global economic recession could impact the number of visitors to the Empire State Building Observatory, as well as our pricing power.

geopolitical unrest. In particular, there have been concerns about the softening of the office real estate market in particular, amidst refinancing challenges of existing low interest rate loans and associated reduced new loan availability and increased costs of loans and related increased expectations of equity returns, coupled with the gradual pace of return-to-office and its impact on the physical utilization of space and asset valuations. Additionally, the risk of a global economic recession could impact the number of visitors to the Empire State Building Observatory, as well as our pricing power.

Despite this global economic backdrop, we believe that ESRT is in a good competitive position with diversified drivers of income across office, retail, multifamily and the Empire State Building Observatory. ESRT’s New York City-focused portfolio is modernized, amenitized, well-located and energy efficient, with indoor environmental quality, competitive rental rates and strong leased percentages. We believe our business is further fortified by the continued performance of our Observatory attraction.

In addition to our diversified portfolio, our business is supported by a well-positioned balance sheet, modest leverage and good access to liquidity as set forth herein. The absence of unaddressed near term debt maturities provides an added degree of security in a rising rate environment. This provides us optionality to execute on capital recycling, acquisitions, and buybacks. As we navigate these uncertain times, we remain prepared for various challenges and situations.

ITEM 3. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

Our future income, cash flows and fair values relevant to financial instruments are dependent upon prevalent market interest rates. We are exposed to interest rate changes primarily on our unsecured revolving credit facility and debt refinancings. In order to mitigate our interest rate risk, we may borrow at fixed rates or may enter into derivative financial instruments such as interest rate swaps or caps on floating rate financial instruments. We are not subject to foreign currency risk and we do not enter into derivative or interest rate transactions for speculative purposes.

As of ~~June~~September 30, 2024, we have interest rate SOFR swap and cap agreements with an aggregate notional value of $~~585~~680.84 million and which mature between October 1, 2024 and November 1, 2033. The "variable to fixed" interest rate swaps have been designated as cash flow hedges and are deemed highly effective with fair values in an asset position of $165.27 million and are included in prepaid expenses and other assets and the fair value of our derivative instruments in a liability position amounted to $2.1 million that is included in accounts payable and accrued expenses on the condensed consolidated balance sheet as of ~~June~~September 30, 2024.

As of ~~June~~September 30, 2024, the weighted average interest rate on the $2.3 billion of fixed-rate indebtedness outstanding was 4.27% per annum, with maturities at various dates through March 17, 2035.

As of ~~June~~September 30, 2024, the fair value of our outstanding debt was approximately $2.12 billion, which was approximately $~~179~~117.97 million less than the book value as of such date. Interest risk amounts were determined by considering the impact of hypothetical interest rates on our financial instruments. These analyses do not consider the effect of any change in overall economic activity that could occur in that environment. Further, in the event of a change of that magnitude, we may take actions to further mitigate our exposure to the change. However, due to the uncertainty of the specific actions that would be taken and their possible effects, these analyses assume no changes in our financial structure.

ITEM 4. CONTROLS AND PROCEDURES

Evaluation of Disclosure Controls and Procedures

We maintain disclosure controls and procedures (as such term is defined in Rule 13a-15(e) and 15d-15(e) under the Exchange Act) that are designed to ensure that information required to be disclosed in our reports under the Exchange Act is processed, recorded, summarized and reported within the time periods specified in the SEC’s rules and regulations and that such information is accumulated and communicated to management, including ESRT's Chief Executive Officer and its Chief Financial Officer, as appropriate, to allow for timely decisions regarding required disclosure. In designing and evaluating the disclosure controls and procedures, management recognizes that any controls and procedures, no matter how well designed and operated, can provide only reasonable assurance of achieving the desired control objectives, and management is required to apply its judgment in evaluating the cost-benefit relationship of possible controls and procedures.

~~Subsequent~~We ~~to the end of the period covered by this report, we~~ carried out an evaluation, under the supervision and with the participation of management, including ~~our~~ESRT's Chief Executive Officer and ~~our~~ESRT's Chief Financial Officer, regarding the effectiveness of our disclosure controls and procedures at the end of the period covered by this report. Based on the foregoing, ~~our~~ESRT's Chief Executive Officer and ~~our~~ESRT's Chief Financial Officer concluded, as of that time, that our disclosure controls were not effective at a reasonable level of assurance as of ~~June~~ September 30, 2024 because of a material weakness identified in the design of certain information technology ("IT") general controls ("ITGCs").

A material weakness (as defined in Rule 12b-2 under the Exchange Act) is a deficiency, or a combination of deficiencies, in internal control over financial reporting such that there is a reasonable possibility that a material misstatement of our annual or interim financial statements will not be prevented or detected on a timely basis. As previously reported in our Form 10-K/A for the year ended December 31, 2023, ~~and~~ our Form 10-Q/A for the fiscal quarter ended March 31, 2024, ~~each~~and ~~filed~~our onForm ~~the~~10-Q ~~date~~for ~~hereof, subsequent to~~ the ~~end~~fiscal ofquarter ~~the~~ended ~~period~~June ~~covered~~30, ~~by this report~~2024, we identified a material weakness in the design of ~~information technology ("IT") general controls ("~~ITGCs") related to IT systems and applications relevant to preparation of our financial statements. In particular, the Company's ITGCs included: (i) controls to approve and monitor changes within information systems and related applications, but the monitoring controls were not designed to ensure a complete population of changes were subject to the control procedures across all relevant IT components and (ii) the controls to approve and monitor user access to information systems and related applications, but the monitoring controls were not designed to review the appropriateness of permissions granted to approved users. As a result, business process controls (automated and manual) that are dependent on the ineffective ITGCs, or that rely on data produced from systems impacted by the ineffective ITGCs, were also deemed ineffective.

4142

Despite the finding of the material weakness, management has concluded that our condensed consolidated financial statements and related notes thereto included herein fairly present in all material respects the financial condition, results of operations and cash flows of the Company as of, and for, the periods presented.

Remediation of the Material Weakness in Internal Control Over Financial Reporting

The Company is in the process of implementing changes associated with the design, implementation and monitoring of ITGCs in the areas of logical access and change management for IT applications that support the Company’s financial statement preparation and reporting processes to ensure that internal controls are designed and operating effectively. Our remediation plans ~~will~~are expected to include:

•Enhancing the current change monitoring control to use an appropriate system source to help ensure a complete population of changes are reviewed to detect if any changes were made outside the Company’s established change control process across all relevant IT components.

•Adding controls to manage the appropriate assignment and maintenance of permission configurations within access groups and the users they are assigned to.

•Increasing the frequency of periodic re-evaluation of user access privileges.

•Training of relevant personnel on the design and operation of our ITGCs over financial reporting.

We believe that these actions, collectively, will remediate the material weakness identified. However, we will not be able to conclude that we have completely remediated the material weakness until the applicable controls are fully implemented and have operated for a sufficient period of time and management ~~has concluded~~concludes, through formal testing, that the remediated controls are operating effectively. We will continue to monitor the design and effectiveness of these and other processes, procedures, and controls and will make any further changes management deems appropriate.

Changes in Internal Control Over Financial Reporting

Except for the ~~unremediated~~continuing remediation of the material weaknesses noted above, there were no changes to our internal control over financial reporting that were identified in connection with the evaluation referenced above that occurred during the period covered by this report that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

PART II. OTHER INFORMATION

ITEM 1. LEGAL PROCEEDINGS

See “Financial Statements – Note 9 Commitments and Contingencies” for a description of legal proceedings.

ITEM 1A. RISK FACTORS

As of ~~June~~September 30, 2024, there have been no material changes to the risk factors~~, except as set forth below~~. See the section entitled "Risk Factors" of our Annual Report on Form 10-K and Form 10-K/A for the year ended December 31, 2023 and our Quarterly Report on Form 10-Q for the fiscal quarter ended June 30, 2024, and any additional factors that may be contained in any filing we make with the SEC.

We have identified a material weakness in our internal control over financial reporting related to information technology general controls. Failure to maintain effective internal control over financial reporting could result in loss of investor confidence and adversely impact our stock price.

We are required under Section 404 of the Sarbanes-Oxley Act to maintain internal control over financial reporting that meets applicable standards. We identified a material weakness in our internal control over financial reporting for the periods ended December 31, 2023 and 2022 related to the design of certain of our ITGCs for information systems and applications used in the preparation of our financial statements. See Part I, ITEM 4, “Controls and Procedures — Material Weakness in Internal Control Over Financial Reporting” for more information. We may not be successful in implementing our remediation efforts or in developing other internal controls. Any failure by us to maintain effective internal control over financial reporting could adversely affect our ability to record, process or report financial information accurately and to prepare financial statements in a

timely manner, which could subject us to litigation or investigations requiring management resources and payment of legal and other expenses, negatively affect investor confidence in our financial statements and adversely impact our stock price.

Under the program, we may purchase our Class A common stock and the Operating Partnership’s Series ES, Series 250 and Series 60 operating partnership units in accordance with applicable securities laws from time to time in the open market or in privately negotiated transactions. The timing, manner, price and amount of any repurchases will be determined by us at our discretion and will be subject to stock price, availability, trading volume, general market conditions, and applicable securities laws. The authorization does not obligate us to acquire any particular amount of securities, and the program may be suspended or discontinued at our discretion without prior notice. As of September 30, 2024, we had $500.0 million remaining of the authorized repurchase amount. There were no repurchases of equity securities during the three months ended September 30, 2024.
