Our properties are geographically concentrated in New York, and adverse state or local economic or regulatory developments could have a material adverse effect on our business and financial condition.

Previous wording

Our commercial portfolio is comprised of properties primarily in New York City as well as in Stamford, Connecticut. As a result, our business is dependent on the New York City economy in general and the market for office, retail and multifamily space in New York City in particular, which exposes us to greater economic and regulatory risks than if we owned a more geographically diverse portfolio. These risks include business layoffs, downsizing, industry slowdowns, and relocations of businesses as well as increases in real estate and other local taxes, and regulatory compliance costs. The current federal tax limits on the deductibility of state and local taxes as well as higher individual tax rate proposals may negatively impact demographic trends in high tax states like New York and Connecticut.

For the year ended December 31, 2024, three of our properties together accounted for approximately 55.5% of our portfolio’s rental revenues, with the Empire State Building individually accounting for approximately 31.9%. Our revenue and cash available for distribution would be materially and adversely affected if any of these three properties were materially damaged or a significant number of their tenants experienced financial strain leading to lease default or bankruptcy filing. Additionally, for fiscal years ended December 31, 2024, 2023 and 2022, we derived revenue of approximately $136.4 million, $129.4 million and $106.0 million, respectively, from the Empire State Building’s Observatory operations. Loss of revenue from the Observatory has in the past and may in the future have a material adverse impact on our results of operations and financial condition.

Previous wording

As of December 31, 2024, our five largest tenants together represented approximately 16.5% of our total commercial portfolio’s annualized rent, with our largest tenant leasing an aggregate of 0.5 million rentable square feet of office space at one of our office properties, representing approximately 5.4% of our total commercial portfolio rentable square feet and approximately 6.1% of our total commercial portfolio annualized rent. Our significant tenants have in the past, and may in the future, experience financial strain leading to lease default or bankruptcy. In such cases, we may not recover our upfront investments in tenant improvement allowances, concessions, and transaction costs like professional fees and commissions. Upon tenant default, we may experience delays and substantial costs in enforcing our rights and protecting our investment. Our business and financial condition could be materially adversely affected if any of our significant tenants were to suffer a downturn in their business, become insolvent, default under their leases, and/or fail to renew on favorable terms or at all.

Downturn in global, national and/or local economies that decreases prospects, demand, occupancy and rental rates for our office, multifamily and retail space can have an adverse impact on the value or price of our assets. For example, the COVID-19 pandemic impacted the entire U.S., including New York and Connecticut where our properties are located. Any future public health crisis or economic downturn could have significant impacts on how people live, work, and travel in ways that have affected and may in the future affect our properties. Such events can also cause delays, cost increases and/or cancellations of planned capital projects. Certain remote work practices implemented in reaction to the pandemic are still in place and have shifted employers and employees away from fully in-person work environments, and a more permanent shift of this type could have an adverse effect on the overall demand for our office space. Additionally, with increased employer flexibility to work from home, current and prospective residents may be less likely to live in dense urban centers or multifamily housing like the properties we own. These trends have impacted our results of operations since the pandemic. If these trends continue, it could impair demand and value at our properties.

As of December 31, 2024, approximately 19.4% of our commercial portfolio’s annualized rent was comprised of retail tenants. In the past, the retail industry has faced reductions in sales revenues and increase in bankruptcies throughout the United States, due to changes in consumer behavior and shift to online shopping. This has reduced rents and demand for physical retail space at street level, which typically commanded the highest rental rates per square foot in office properties. This has also reduced rents and demand for physical retail space located above or below street level. Continued reduced demand, rental rates and occupancy rates for our retail space could have a material adverse effect on our business and financial condition.

The leasing of real estate in New York City and its surrounding metropolitan area is highly competitive in rental rates, location, services and property condition. We have seen increased competition from lessors in offering concessions, short term, amenities, indoor environmental quality and sustainability certifications. See Part I, ITEM 1, “Business— Competition” for more information. Increased competition challenges our ability to lease space and maximize our effective rents. Upon expiration of leases at our properties and with respect to our current vacant space, we may be required to make rent or other concessions to tenants, accommodate increased requests for renovations, build-to-suit remodeling and other improvements or provide additional services to our tenants. In addition, eight of our existing properties are pre-war office properties, which may require more frequent and costly maintenance to retain existing tenants or attract new tenants than newer properties. As a result, and due to the increased competition from lessors in the greater New York City area, we have made, and may have to make, significant capital or other expenditures in order to maintain the competitiveness of our properties. There can be no assurances that any such expenditure would result in higher occupancy, higher rental rates or deter existing tenants from relocating to properties owned by our competitors. If we are unable to match the competition for lack of capital or other reasons, we may fail to attract new tenants or to renew existing tenants.

We may be unable to renew leases or re-lease vacant space on favorable terms or at all as leases expire.

Current wording

We may be unable to renew leases or re-lease vacant space on favorable terms or at all as leases expire or lease vacant space after redevelopment.

Previous wording

As of December 31, 2024, we had approximately 0.6 million rentable square feet of vacant space in our office and retail properties. In addition, leases representing 6.5% and 8.2% of the square footage of the office and retail properties in our commercial portfolio will expire in 2025 and 2026, respectively. We cannot be assured that leases scheduled to expire will be renewed or that our properties will be re-leased at net effective rental rates at or above the current average. If the terms of the renewal or re-leasing are less favorable than current terms, or we fail to re-lease such spaces at all, our business, results of operations, cash flow and financial condition will be negatively affected.

Current wording

As of December 31, 2025, we had approximately 0.7 million rentable square feet of vacant space in our office and retail properties, including properties that are under redevelopment. In addition, leases representing 5.1% and 7.3% of the square footage of the office and retail properties in our commercial portfolio will expire in 2026 and 2027, respectively. We cannot be assured that leases scheduled to expire will be renewed or that our properties will be re-leased at net effective rental rates at or above the current average. If the terms of the renewal or re-leasing are less favorable than current terms, or we fail to re-lease such spaces at all, our business, results of operations, cash flow and financial condition will be negatively affected.

Previous wording

Generally, our multifamily leases are for twelve months or less. If the terms of the renewal or reletting are less favorable than current terms, our business, results of operations, cash flow and financial condition will be negatively affected. Given their short-term lease structure, our multifamily rental revenues are more sensitive to market declines.

Current wording

Generally, our multifamily leases range from one to two years.

We license the use of the Empire State Building broadcasting mast to third-party television and radio broadcasters. During the year ended December 31, 2024, we derived approximately $15.2 million of revenue (excluding tenant reimbursement income) from such broadcasting licenses and related leases, as compared with about $21 million at its peak. Competition from other broadcasting operations has had a negative impact on revenues, and lease renewals have yielded reduced revenue, and higher operating expenses and capital expenditures. Our broadcast licensees also face a range of competition from advances in technologies and alternative methods of content delivery in their respective industries, as well as changes in consumer behavior, which may reduce the demand for over-the-air broadcast licenses. Government regulations may materially and adversely affect our broadcast revenue by reducing the demand for broadcast licenses by making more spectrum available for wireless broadband service providers.

Real estate investments are relatively difficult to sell quickly. Return of capital and realization of gains from an investment generally will occur upon disposition or refinancing. In addition, the Code imposes restrictions on the ability of a REIT to dispose of properties that are not applicable to other types of real estate companies. We may be unable to realize our investment objectives by sale, other disposition or refinancing at attractive prices within any given period of time.

We may dispose of properties in transactions that are intended to qualify as “like kind exchanges” under Section 1031 of the Code. It is possible that the qualification of a transaction as a like-kind exchange could be successfully challenged and determined to be currently taxable. In such case, our taxable income and earnings and profits would increase. In some circumstances, we may be required to pay additional dividends or, in lieu of that, corporate income tax, possibly including interest and penalties. As a result, we may be required to borrow funds to pay additional dividends or taxes, and any payment of taxes could cause us to have less cash available to distribute to our shareholders. In addition, if a like-kind exchange was later determined to be taxable, we may be required to amend our tax returns for the applicable year in question, including any information reports we sent our shareholders. We could also be subject to significant indemnity obligations if the applicable property was subject to a tax protection agreement.

As of December 31, 2024, we had total debt outstanding of approximately $2.3 billion inclusive of total mortgages of approximately $704.3 million. See “Financial Statements— Note 5 Debt” in this Annual Report on Form 10-K for further information. Our organizational documents do not limit the debt we may incur, and we may incur significant additional debt to finance future acquisition and development activities. Our current and potential levels of debt, and the limitations in our loan documents could have significant adverse consequences to our cash flow and our ability to service and refinance our debt. We may be forced to dispose of one or more of our properties, possibly on disadvantageous terms. We may default on our debt obligations, in which case the lenders may accelerate our debt obligations and foreclose on any mortgaged properties. Our default on one debt with cross-default provisions could result in a default on other debt. In addition, our revolving credit facility and related term loan bear interest at a variable rate. We may incur indebtedness in the future that also bears interest at a variable rate or may be required to refinance our debt at higher rates. If any one of these events were to occur, our results of operations, cash flow, financial condition, and ability to service debt and to make distributions could be adversely affected.

Our debt instruments may restrict our financial and operational flexibility. For example, our lockbox and cash management agreements may require income from our properties to be deposited directly into lockbox accounts controlled by our lenders from which we receive cash after funding of defined operating and capital costs. As a result, we may be forced to borrow additional funds in order to make distributions. Additionally, many of our debt instruments contain financial covenants that impact how we run our business, including required ratios for debt-to-assets, adjusted EBITDA to consolidated fixed charges or debt service. Our partnership agreement may restrict our ability to pay dividends if we fail to pay the cumulative distributions on preferred units. See Part II, ITEM 7, “Management’s Discussion and Analysis of Financial Condition and Results of Operations— Liquidity and Capital Resources” for more information.

Because of the distribution requirements to maintain our status as a REIT (See Part I, ITEM 1, “Business— Our Tax Status”), we may not be able to fund future capital needs, including any acquisition financing, from operating cash flow and may need to rely on third-party sources. Additionally, our access to third-party sources of capital depends, in part, on general economic and market conditions, including the cost and availability of credit, government action or inaction and its effect on the state of the capital markets, the market’s perception of our growth potential, as well as our then current financial condition. Absent needed capital, we may not be able to acquire or develop properties when opportunities exist, satisfy our debt obligations or make cash distributions to our securityholders necessary to maintain our qualification as a REIT.

Our properties are concentrated in the New York metropolitan area. Natural disasters and physical climate risk including earthquakes, storms, storm surges, tornados, floods, extreme temperatures, hurricanes and rising sea levels, could cause significant damage or limit access to our properties and adversely impact the areas in which we operate. These conditions could result in declining demand for our commercial and multifamily properties, compromise our ability to operate the buildings to the requirements and parameters set forth in our leases, make insurance less affordable or available, and increase the cost of energy and utilities at our properties. Also, certain of our properties could not be rebuilt to their existing height or size under current land use laws. In that event, we may have to upgrade such property to meet code requirements. Our disaster recovery and business continuity plans may not be adequate to address these risks.

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. 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, without regard to whether we comply with environmental laws in doing so. 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. For example, a portion of the Metro Tower site is currently used for automobile parking and was formerly leased to a fueling facility, and we have post-closing obligations related to our Westport properties sold in 2023 related to remediation of storage tank and soil contamination. See Part I, ITEM 1, "Business— Environmental Matters" for further information. 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.

In addition, our properties are subject to various federal, state and local environmental and health and safety laws and regulations, and noncompliance 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 or increase liability for noncompliance. 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. 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. See "We may incur significant costs to comply with environmental laws, in particular New York City’s Local Law 97"in this section.

Previous wording

We may become subject to new compliance requirements and/or new costs or taxes associated with natural resource or energy or utility usage and related emissions (such as a “carbon tax”), which could increase our operating costs. In particular, as the owner of large covered commercial and multifamily 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 covered building establishes annual limits for greenhouse gas emissions, requires yearly compliance reports beginning in May 2025 for calendar year 2024 performance, and imposes penalties for emissions above such limits. While we are actively working to reduce our carbon emissions, there can be no assurance that we will be able to operate within the limits of Local Law 97, or that the costs of compliance and/or penalties will not be material. Based upon our present understanding of the law and calculations related thereto, we expect to pay no Local Law 97 fine on any covered building in our portfolio in the 2024-2029 period of enforcement.

Current wording

In particular, as the owner of large covered commercial and multifamily buildings in New York City, we are subject to Local Law 97, which establishes annual greenhouse gas emissions limits for covered buildings and imposes penalties for emissions that exceed applicable thresholds. While we currently expect, based on our present understanding of the law and implementing rules and our internal projections of building emissions, to operate within the applicable limits during the 2024–2029 enforcement period, our expectations are based on assumptions regarding building performance, tenant energy usage and utility grid emissions factors. Regulatory developments, changes in enforcement guidance, changes in building operations, tenant behavior, energy consumption patterns, or utility emissions factors could cause us to exceed emissions limits or incur additional compliance costs or penalties, which could be material.

As of December 31, 2024, we have collective bargaining agreements that cover 429 employees, or 64% of our workforce, that service our portfolio. Our inability to negotiate acceptable renewals as existing agreements expire could result in strikes or work stoppages and disrupt our operations. In any such event for any extended period of time, we would likely engage temporary replacement workers, which would result in increased operating costs.

These threats, which continue to increase in number, intensity and sophistication, include malware, ransomware, computer viruses, phishing, unauthorized access, and other vectors used by hackers, terrorists, foreign governments, and other actors. Cyber threats and attacks on our Company have included and could in the future include internal and external attempts to gain unauthorized access to our data and computer systems to disrupt our operations or the operations of our tenants and residents, destroy property, or steal confidential information. There is no guarantee that our controls or measures to prevent or mitigate such attacks will be successful. A cyberattack could compromise the confidential information of our employees, tenants, residents, customers, and vendors, and disrupt our business operations and relationships. A security breach could require us to expend significant resources to remediate and may subject us to litigation, damages, penalties, fines, governmental investigations and enforcement actions or termination of leases. Any compromise of our security could also result in a violation of applicable privacy laws (e.g., Observatory customer data, Company employee data, or residential data at multifamily properties). These consequences could result in negative legal consequences as well as significant damage to our business and financial condition and reputation. New laws and regulations related to data privacy and security pose increasingly complex compliance challenges and costs across multiple jurisdictions, which could negatively impact our business and financial condition.

Our vendors and other parties with whom we do business face similar threats and an incident at one of these entities could adversely impact our business. These entities are typically outside our control and may have access to certain of our information with varying levels of security and cybersecurity resources. New laws and regulations related to data privacy and security pose increasingly complex compliance challenges and costs across multiple jurisdictions, which could negatively impact our business and financial condition. We have begun the use of AI capabilities in our business and operations. We may not be successful in identifying or resolving issues before they arise. There can be no assurance that we or our service providers will properly implement AI, and the failure to do so could similarly result in negative legal consequences as well as significant damage to our business and financial condition and reputation.

Previous wording

We must rely on ESRT, as our general partner, to manage our affairs and business. ESRT is subject to risks that may affect its financial and other conditions, including particularly adverse consequences if it fails to qualify as a REIT for U.S. federal income tax purposes. ESRT's qualification as a REIT is governed by highly technical and complex provisions of the Code for which there are only limited judicial or administrative interpretations and depends on various facts and circumstances that are not entirely within its control. In addition, legislation, new regulations, administrative interpretations or court decisions may significantly change the relevant tax laws and/or the U.S. federal income tax consequences of qualifying as a REIT. Thus, while we and ESRT intend to operate so that ESRT will qualify as a REIT, there can be no assurance that ESRT will so qualify for any particular year. These considerations also might restrict the types of assets that we can acquire in the future. If, with respect to any taxable year, ESRT fails to maintain its qualification as a REIT and does not qualify under statutory relief provisions, it could not deduct distributions to shareholders in computing its taxable income and would have to pay U.S. federal income tax on its taxable income at regular corporate rates and thus reduce funds available for distribution and debt service, and ESRT would not be required to make distributions until it re-qualified as a REIT which would not be permitted for the four taxable years following its disqualification, unless it gained relief under relevant statutory provisions.

To enable ESRT to comply with REIT requirements, we may have to forego and/or liquidate attractive investments or borrow funds and we may be subject to tax.

Current wording

To enable ESRT to comply with REIT requirements, we may have to forego and/or liquidate otherwise attractive investments or borrow funds and we may be subject to tax.

Previous wording

To qualify as a REIT (and avoid certain taxes to which it would be subject notwithstanding its status as a REIT), ESRT must meet, on an ongoing basis, certain tests regarding the nature and diversification of its assets and its income. Because substantially all of ESRT's assets consists of our OP units, and substantially all of ESRT's income consists of income allocations with respect to such units, ESRT's ability to satisfy these tests will depend on the composition of our assets and income. Similarly, in order to be treated as a partnership for U.S. federal income tax purposes, we must meet certain annual tests relating to the sources of our gross income. In order to meet these tests and to allow ESRT to meet these tests, we may be required to forego investments that we otherwise would make or to liquidate otherwise attractive investments.

Previous wording

ESRT intends to distribute its net income to securityholders in a manner intended to satisfy the REIT 90% distribution requirement (See Part I, ITEM 1, “Business— Our Tax Status”) and to avoid U.S. federal income tax and the 4% nondeductible excise tax. Our partnership agreement provides that we will make sufficient distributions to ESRT to enable it to satisfy these distribution requirements. Any failure to do so will incur substantial entity level tax and/or disqualification as a REIT with the adverse tax consequences and limits on re-qualification described above in this section. As a result, we may be required to make distributions to ESRT at disadvantageous times or when we do not have funds readily available for distribution. These actions could have the effect of reducing our income and amounts available for distribution to our securityholders.

Previous wording

To treat income from our Observatory and broadcast facilities as qualified REIT income, we rely upon private letter rulings that such income is qualifying rent for our REIT qualification. See Part I, ITEM 1, “Business— Our Tax Status.” We are entitled to rely upon these private letter rulings only to the extent that we did not misstate or omit a material fact in the ruling request and that we continue to operate in accordance with the material facts described in such request, and no assurance can be given that we will always be able to do so. If we were not able to treat the rent that our Company receives from Observatory TRS as qualifying income, we would be required to restructure how we operate the Observatory, which would likely require us to cede operating control of the Observatory by leasing the Observatory to an affiliate or third-party operator. If we were not able to treat our broadcast license fees as qualifying income for purposes of the REIT gross income tests, we would be required to enter into the license agreements through a TRS, which would cause the license fees to be subject to U.S. federal income tax and accordingly reduce the amount of our cash flow available to be distributed to our securityholders. In either case, if we are not able to appropriately restructure our operations in a timely manner, we would likely realize significant income that does not qualify for the REIT gross income tests, which could cause ESRT to fail to qualify as a REIT.

As a result of the unrealized built-in gain attributable to a property at the time of contribution, some holders of operating partnership units, including our Chairman and Chief Executive Officer, Anthony E. Malkin, and our Chairman Emeritus, Peter L. Malkin, may suffer different and more adverse tax consequences than other holders of operating partnership units upon the sale or refinancing of the properties owned by us, including disproportionately greater allocations of items of taxable income and gain upon a realization event. As those holders will not receive a correspondingly greater distribution of cash proceeds, they may have different objectives regarding the appropriate pricing, timing, transaction structure and other material terms of any sale, exchange or refinancing of certain properties, or whether to sell, exchange or refinance such properties at all. As a result, the effect of certain transactions on Messrs. Malkin may influence their decisions affecting these properties and may cause such members of ESRT’s senior management team to attempt to delay, defer or prevent a transaction that might otherwise be in the best interests of our other securityholders, or to structure such transactions in ways that would mitigate the above tax consequences to Messrs. Malkin.

As of December 31, 2024, QIA had a 10.90% fully diluted interest in ESRT, which represented 17.97% of the outstanding Class A common stock of ESRT. Pursuant to the terms of ESRT’s stockholders agreement with QIA, QIA generally has the right (but not the obligation) to maintain its fully diluted economic interest in ESRT by purchasing additional shares of ESRT’s Class A common stock when we or ESRT issue additional common equity securities from time to time. While QIA has agreed to limit its voting power on all matters presented to ESRT’s securityholders to no more than 9.9% of total number of votes entitled to be cast, QIA has also agreed to vote its shares in favor of the election of all director nominees recommended by ESRT’s Board. The interests of Mr. Malkin and QIA could conflict with or differ from your interests as a holder of our operating partnership units, and these large securityholders may exercise their right as securityholders to restrict our ability to take certain actions that may otherwise be in the best interests of our securityholders. This concentration of voting power might also have the effect of delaying or preventing a change of control that our securityholders may view as beneficial.

Conflicts of interest exist or could arise in the future as a result of the relationships between ESRT and its affiliates, on the one hand, and our Company or any partner thereof, on the other. For example, a potential acquisition or disposition opportunity could be opportunistic to the REIT while tax disadvantageous to certain OP holders. ESRT’s directors and officers have duties to ESRT and its shareholders under applicable Maryland law in connection with their management of ESRT. At the same time, ESRT, as our general partner has fiduciary duties and obligations to us and our limited partners under Delaware law and our partnership agreement. ESRT’s fiduciary duties and obligations to us as general partner may come into conflict with the duties of ESRT’s directors and officers to ESRT, which may impede business decisions that could benefit our securityholders. Pursuant to our partnership agreement, our limited partners have agreed that in the event of a conflict in the duties owed by ESRT's directors and officers to ESRT and ESRT's securityholders and the fiduciary duties owed by ESRT, in its capacity as general partner of us, to such limited partners, ESRT will fulfill its fiduciary duties to such limited partners by acting in the best interests of ESRT's securityholders.

We intend to make distributions to our securityholders. All dividends and distributions will be made at the discretion of our sole general partner, ESRT, acting through its Board, and will depend on our earnings, financial condition, maintenance of ESRT’s REIT qualification and other factors as ESRT’s Board may deem relevant from time to time. If sufficient cash is not available for distribution from our operations, we may have to fund distributions from working capital or to borrow to provide funds for such distribution, or to reduce the amount of such distribution. We cannot assure you that our distributions will be made or sustained. Our failure to meet the market’s expectations with regard to future earnings and cash distributions likely would adversely affect the market price of ESRT’s Class A common stock and our traded OP units.
