COVID-19 IMPACT It has been a little over a year since COVID-19 collided with New York City. Throughout the year we managed for three absolutes: (i) serve our customers, (ii) responsibly protect our colleagues, and (iii) focus on long-term shareholder value. We had positioned ESRT for a downcycle, and to date we have successfully pivoted and ﬂexed through a year of challenges. In the same time period, we bid farewell to our President and Chief Operating Ofﬁcer and welcomed our new Chief Financial Ofﬁcer, Chief Investment Ofﬁcer, and Chief Accounting Ofﬁcer. We kept our buildings open with robust health and safety protocols and leased space in a challenging market. We closed and reopened the Empire State Building Observatory. We repeatedly adjusted our operations and made prudent and difﬁcult choices to implement reductions in force and costs. We have gratitude and appreciation for our remarkable, dedicated, and effective ESRT colleagues who have accomplished through it all. It is a great reward to work with fantastic people on behalf of our stakeholders. 2020 2020 was a year of actions taken in response to challenges: Implemented plans and actions to allow employee and tenant reentry with conﬁdence to our buildings; Leased over 920 thousand square feet despite lockdowns that disrupted property tours and tenant decision-making; Improved our rent collections over the course of the year; Managed our operating and capital expenses amidst an uncertain environment; and Assisted our smaller retail tenants with percentage rent deferral agreements. We have gratitude and appreciation for our remarkable, dedicated, and effective ESRT colleagues who have accomplished through it all. It is a great reward to work with fantastic people on behalf of our stakeholders. 381486_ESRT20-2602 2020 Annual Report_OUT_NAR.indd 2 3/26/21 12:12 AM Our December 2019 completion of the Empire State Building Observatory redevelopment yielded record January and February 2020 results. Then, in mid-March 2020 we were required by government authorities to close the Observatory. Our redevelopment had a focus on Indoor Environmental Quality (IEQ), including use of MERV-13 ﬁlters, active bi-polar ionization, and improved ventilation. These IEQ features, along with enhanced health and safety protocols, positioned us to reopen the 86th ﬂoor observation deck in mid-July 2020, one of New York City’s earliest tourist attractions to do so. Today, our visitors enjoy the Observatory with conﬁdence, and excellent reviews of their experience. Visits to the Observatory continue to grow off a low base, and we welcome the ongoing relaxation of travel restrictions to restore its bottom-line contribution to our performance. OUR COMPETITIVE ADVANTAGE Our strategy is to manage our portfolio proactively to drive occupancy through the lease up of vacant redeveloped space and increase rental rates; build upon and earn recognition for our existing Environmental, Social and Governance (ESG) leadership position; pursue attractive acquisition and redevelopment opportunities for external growth; and maintain a ﬂexible, well-capitalized balance sheet that provides operating runway and enables us to take advantage of opportunities that may arise. Our buildings and their unique combination of modernization for the 21st Century, location, leadership in sustainability and IEQ, and value have a sharp competitive edge. We believe that we have entered a time in which tenants will choose landlords that can help them fulﬁll their corporate ESG objectives through buildings which help them attract and retain talent. ENVIRONMENTAL, SOCIAL AND GOVERNANCE (ESG) ESRT is well-positioned in a world that views businesses through an ESG lens. We have more than a decade’s focus on energy efﬁciency, healthy buildings, IEQ, and sustainability. Our work to deliver long-term value to our shareholders through excellence in these areas revolves around three key themes: 1) Transparency, alignment and best-in-class practices; 2) Leadership in policy setting and tenant education; and 3) Implementation, active monitoring and measurement in our portfolio. Today, our visitors enjoy the Observatory with conﬁdence, and excellent reviews of their experience. Visits to the Observatory continue to grow off a low base, and we welcome the ongoing relaxation of travel restrictions to restore its bottom-line contribution to our performance. 381486_ESRT20-2602 2020 Annual Report_OUT_NAR.indd 3 3/26/21 12:12 AM In 2020, we received recognition from a number of rigorous, evidence-based, third-party veriﬁed ratings. ESRT’s portfolio is the ﬁrst commercial portfolio in the Americas to achieve the WELL Health-Safety Rating; 76% of our eligible portfolio is ENERGY STAR certiﬁed; and 100% percent of the portfolio is fully powered by renewable wind electricity. In our inaugural year, ESRT earned a GRESB 5 Star Rating, Green Star recognition, an “A” for disclosure, and a score of 88 that puts us in the top 20% of all rated companies. We were named a Fitwel Champion. In February 2020, a study published by Morgan Stanley stated that ESRT’s portfolio has the lowest KgCO2 psf of New York City ofﬁce REITs1. Our disclosure practices align with GRI Standards, and TCFD and SASB2 reporting frameworks. Our entire Board of Directors is engaged on ESG oversight. We have delegated speciﬁc responsibilities to each board committee and adopted the inclusion of an ESG metric as part of executive management incentive compensation. Our leadership positions, partnerships and engagement keep us informed on all the latest developments and put us in a position to inﬂuence and inform emerging industry standards and government policy. Our Chairman, President and CEO serves as the Chair of the Real Estate Roundtable’s Sustainability Policy Advisory Committee and is the sole industry representative on NYC’s Climate Mobilization Advisory Board for the implementation of Local Law 97. Since 2014, we have tracked and reported on our progress in energy efﬁciency, water efﬁciency, healthy work environments for our tenants and employees, and waste diversion. We have an ROI-driven focus on results and we measure, verify, manage, and evaluate performance against our ESG goals. We are active in our work to serve as a case study once again in further energy efﬁciency efforts and expect to hear more from us on this front. We regularly engage with our tenants to educate and encourage them to design, build and operate their own spaces in an energy efﬁcient and healthier way for their employees. ESRT’s portfolio is the ﬁrst commercial portfolio in the Americas to achieve the WELL Health-Safety Rating; 76% of our eligible portfolio is ENERGY STAR certiﬁed; and 100% percent of the portfolio is fully powered by renewable wind electricity. 1.

DIVERSITY, EQUITY, AND INCLUSION At ESRT, we have built our Diversity, Equity and Inclusion (DEI) initiatives around a system of beliefs and values: Diverse perspectives and experiences enhance effective decision-making and innovation. An engaged and diverse team does not happen on its own, we must take proactive steps. When we ensure the well-being, development, and full potential of all our teammates, we perform our best. Speciﬁc goals must be set so that we can measure and verify we meet our goals and commitments. In 2020, we strengthened and formalized our commitment, established goals and metrics, and established transparency in reporting to our board. We have formal policies which specify DEI targets in candidate pools for internships and new hires. We will maintain annual internal conversations to ensure colleagues understand each other’s perspectives. We study and report to our board on pay parity. We have implemented new initiatives to set expectations for, and will begin to collect data from, vendors, services providers, and suppliers to promote, encourage, and report on diversity in their organizations. Please consult our proxy for further information. ESRT VERSION 2.0 In 2020, we made the following management additions to ESRT: Christina Chiu, Executive Vice President and Chief Financial Ofﬁcer, leads our accounting, ﬁnance and investor relations functions and has quickly and tirelessly added value in other areas of the Company as well; Steve Horn, Senior Vice President and Chief Accounting Ofﬁcer, steers our accounting function; and Aaron Ratner, Senior Vice President and Chief Investment Ofﬁcer, leads our sourcing of external growth opportunities. 381486_ESRT20-2602 2020 Annual Report_OUT_NAR.indd 5 3/26/21 12:12 AM Amidst an uncertain macro environment, we kept our focus on the generation of shareholder value, prudently allocated capital, and maintained a ﬂexible balance sheet to provide us with an operating runway. We also refreshed and added diversity to our board. Since 2017, we have added 4 new directors, 3 of whom are diverse in terms of gender and/or ethnicity. In 2020, we appointed the following board members: Grant H. Hill, our new independent Director, brings expertise in consumer branding, leadership and team skills and entrepreneurial successes; and R. Paige Hood, our new independent Director, provides expertise in real estate ﬁnance with extensive experience through multiple cycles. CAPITAL ALLOCATION Amidst an uncertain macro environment, we kept our focus on the generation of shareholder value, prudently allocated capital, and maintained a ﬂexible balance sheet to provide us with an operating runway. We avoided asset purchases at the end of a bull market, executed ﬁnancings at attractive terms, and maintained modest leverage levels. ESRT has runway and ﬂexibility in uncertain times. We used that ﬂexibility to engage in share buybacks at the low end of our historic trading range. The cumulative buyback total is $147.2 million at a weighted average price of $8.34 per share3. We obtained debt at attractive rates and long tenors with well-laddered maturities in ﬁnancing transactions in March and November of 2020. These transactions validate the quality of our assets and our ability to access the capital markets through a variety of channels. The Company took advantage of a unique situation - no taxable income and therefore no requirement to pay a dividend in 2020 - and temporarily suspended our common dividend for the third and fourth quarters of 2020 to preserve and enhance shareholder value in an uncertain environment. We have continued that suspension for the ﬁrst and second quarters of 2021 and the Board of Directors will continue to review regularly our capital allocation decisions. Our investment team actively underwrites acquisition opportunities in which our balance sheet strength and redevelopment expertise can be brought to bear and we are open-minded in the types of deals we will consider. That said, we are in a marathon, not a sprint, and maintain a prudent approach to capital deployment. 3. As of March 15, 2021. 381486_ESRT20-2602 2020 Annual Report_OUT_NAR.indd 6 3/26/21 12:12 AM LOOK AHEAD TO 2021 We have conﬁdence in the future of New York City, and are realistic about the phase of the cycle in which we ﬁnd ourselves. Our role is to provide energy efﬁcient ofﬁce space in healthy buildings with IEQ for companies with bright futures and the smart, ambitious and motivated individuals who work for them in this great city that offers a unique mix of human capital, multiculturalism and amenities. We are committed to continue to evolve and be a part of a reinvention for the good of our city, its people, and the economy that makes us the only capital of the world that is neither capital of a state nor a country. We thank our deeply engaged Board of Directors who have been supportive and engaged every step of the way, with more direct outreach to our large investors than ever before and genuine concern for our well-being and support for our mission during a tumultuous year. On a personal note, I am incredibly fortunate to be surrounded by team members who run to the ﬁre, not away from it. No matter what happens, our people, our planning and prudence, and our balance sheet position us well for any market environment. On behalf of all of us here at ESRT, we thank our stockholders and all our stakeholders for their continued support. ONWARD AND UPWARD. On a personal note, I am incredibly fortunate to be surrounded by team members who run to the ﬁre, not away from it. Anthony E.

BUSINESS Overview PART I We are a self-administered and self-managed real estate investment trust ("REIT") that owns, manages, operates, acquires and repositions office and retail properties in Manhattan and the greater New York metropolitan area, including the Empire State Building, the world's most famous building. As of December 31, 2020, our total portfolio contained 10.1 million rentable square feet of office and retail space, and was 85.9% occupied. Including signed leases not yet commenced, our total portfolio was 88.7% leased. As of December 31, 2020, we owned 14 office properties (including three long-term ground leasehold interests) encompassing approximately 9.4 million rentable square feet of office space, which were approximately 85.6% occupied or 88.3% leased including signed leases not yet commenced. Nine properties are located in the midtown Manhattan market and encompass approximately 7.6 million rentable square feet of office space, including the Empire State Building. Our Manhattan office properties also contain 0.5 million rentable square feet of premier retail space on their ground floor and/or contiguous levels. Five office properties are located in Fairfield County, Connecticut and Westchester County, New York, encompassing approximately 1.8 million rentable square feet. The majority of square footage for these five properties is located in densely populated metropolitan communities with immediate access to mass transportation. Additionally, we have entitled land at the Stamford Transportation Center in Stamford, Connecticut, adjacent to one of our office properties, that will support the development of an approximately 0.4 million rentable square foot office building and garage, which we refer to herein as Metro Tower. As of December 31, 2020, our portfolio also included four standalone retail properties located in Manhattan and two standalone retail properties located in the city center of Westport, Connecticut, encompassing 0.2 million rentable square feet in the aggregate. As of December 31, 2020, our standalone retail properties were 97.1% leased. The Empire State Building offers panoramic views of New York and neighboring states from its world-famous 86th and 102nd floor observatories which historically have drawn millions of visitors each year. The 86th floor observatory has a heated 360-degree outdoor deck as well as indoor viewing galleries to accommodate guests day and night, all year-round. The 102nd floor observatory is entirely indoors and offers a 360-degree view of New York City from 1,250 feet above ground. Prior to the outbreak of the novel Coronavirus Disease 2019 ("COVID-19"), the number of visitors to the observatories was approximately 3.8 million and 3.5 million for the years ended December 31, 2018 and 2019, respectively. More than 60% of visitors historically have been international travelers. Due to government mandated closure from March 16, 2020 to July 20, 2020, travel restrictions on international and domestic tourists, and other impacts of the pandemic, the number of visitors declined for the year ended December 31, 2020 to 0.5 million visitors. We had 422,000 visitors in the first quarter 2020, no visitors in the second quarter 2020, 30,000 visitors in the third quarter 2020 and 55,000 visitors in the fourth quarter 2020. We were organized as a Maryland corporation on July 29, 2011. Our operating partnership holds substantially all of our assets and conducts substantially all of our business. As of December 31, 2020, we owned approximately 60.1% of the units of partnership interest in our operating partnership ("OP Units"). Empire State Realty Trust, Inc., as the sole general partner in our operating partnership, has responsibility and discretion in the management and control of our operating partnership, and the limited partners in our operating partnership, in such capacity, have no authority to transact business for, or participate in the management activities of, our operating partnership. We elected to be taxed as a REIT and have operated in a manner that we believe allows us to qualify as a REIT for U.S. federal income tax purposes commencing with our taxable year ended December 31, 2013. Impact of COVID-19 From March 2020, the COVID-19 pandemic created a global crisis with attendant uncertainty, volatility and disruption of the economy and social systems in the United States and globally. The stringent measures implemented by governments around the world to attempt to help control the spread of the virus have included business shutdowns and curtailments, and restrictions, prohibitions on all manner of events and gatherings, quarantines, "shelter-in-place" and "stay-at-home" orders, curfews, social distancing, and other measures. The impacts have been especially harsh on the Northeastern United States, specifically New York City and the tri-state region, the business area for the company. This has materially, adversely impacted parts of our business and we continue to face challenges. Amidst these challenges, we moved swiftly and: • • reduced operating expenses across our portfolio; reduced general and administrative costs, including reductions in executive compensation, as well as salary reductions for nearly all employees who earned in 2019 more than $200,000 in salary and cash bonus compensation, as well as certain other employees involved in the operation of the observatories at the Empire State Building; 3 • • • bolstered our balance sheet with an additional $180.0 million, ten year secured financing to maximize operating runway and we have no outstanding debt maturities until November 2024 and $1.6 billion of liquidity as of December 31, 2020; instituted comprehensive health and safety protocols for our workforce and tenants; and achieved a number of Environmental, Social and Governance ("ESG") accomplishments. Additional information regarding the impact of COVID-19 on our business can be found under the section titled "Impact of COVID-19" included within Part II, Item 7, "Management's Discussion and Analysis of Financial Condition and Results of Operations," of this Annual Report on Form 10-K and risks related to COVID-19 can be found under Part I, Item 1A, "Risk Factors," of this Annual Report on Form 10-K. Our Competitive Strengths We believe that we distinguish ourselves from other owners and operators of office and retail properties due to the following competitive strengths: • Irreplaceable Portfolio of Office Properties in Midtown Manhattan at an Attractive Value Proposition. Our Manhattan office properties are located in one of the most prized office markets in the world due to a combination of supply constraints, high barriers to entry, and long-term prospects for job creation. These properties have undergone significant redevelopment to become fully modernized, with a focus on energy efficiency and indoor environmental quality. Historically, the Empire State Building, our flagship property, has also provided us with a significant source of income from its observatories. We believe the high quality of our buildings, services and amenities, their desirable locations and commuter access to mass transportation represent a value proposition with rents at a substantially lower price point than new construction and with a premium product offering over similar vintage unrenovated buildings. Management believes these properties could not be replaced today for the value imputed by our current stock price. • Well Located Retail Locations in Densely Populated Metropolitan Communities . Our retail properties are comprised of retail space at the base of our Manhattan office properties, four standalone retail properties in Manhattan and two contiguous standalone retail properties in Westport, Connecticut. All of the Manhattan properties are located in historically dynamic retail corridors with convenient access to mass transportation, a diverse tenant base and high pedestrian traffic and/or main destination locations, qualities which set them apart from retail properties in the high rent or low traffic corridors. Our Westport, Connecticut retail properties are located on Main Street, the main pedestrian thoroughfare in Westport, and have the advantage of being adjacent to a large public parking plaza. Our retail tenants cover a number of industries, and include Charles Schwab, JP Morgan Chase, Sephora, Target, TJ Maxx, Urban Outfitters, Lululemon, Athleta, Starbucks, ATT Mobile, Sprint, Chipotle, Footlocker, and Walgreens, among others. We acknowledge that the COVID-19 pandemic has materially impacted in-store retail, with particular damage to locations typically patronized by daytime workers. While we are constructive on the long-term trends of retail that serves daytime work populations, and well-located retail in general, the near term impacts of COVID-19 on retail are material and negative. • • Expertise in Repositioning and Redeveloping Manhattan Office Properties. We redevelop, and reposition Manhattan office properties. As of December 31, 2020, we have invested a total of $948.1 million (excluding tenant improvement costs and leasing commissions) in our Manhattan office properties since we assumed control of the day- to-day management of these properties in the period between 2002 through 2006. Through our redevelopment work, our properties have become fully modernized, with a focus on energy efficiency and indoor environmental quality, and we have added tenant amenities such as the tenant-only fitness center and conference center at the Empire State Building, and a recently completed tenant-only lounge at 1400 Broadway. Leader in Energy Efficiency Retrofits. We have pioneered certain practices in energy efficiency, beginning at the Empire State Building where we partnered with the Clinton Climate Initiative, Johnson Controls Inc., Jones Lang LaSalle and the Rocky Mountain Institute to create and implement a groundbreaking, replicable process for integrating energy efficiency retrofits in the existing built environment. The reduced energy consumption lowers costs for us and our tenants, and we believe creates a competitive advantage for our properties. We believe that higher quality tenants in general place a higher priority on sustainability, controlling costs, and minimizing contributions to greenhouse gases. As a result of our efforts, approximately 76% of our portfolio square feet is Energy Star certified, including the Empire State Building, even with the more stringent ENERGY STAR scoring methodology rolled out in late 2019. As a result of the energy efficiency retrofits, we estimate that the Empire State Building has reduced energy use by 43% of its pre-retrofit level of energy use, resulting in over $6.9 million of annual energy cost savings at pre-retrofit utility rate levels. We have implemented other cost justified energy efficiency retrofit projects in our Manhattan and greater New 4 York metropolitan area office properties based on our work at the Empire State Building. Based on our calculations, we have no exposure to fines in 2024 under New York City's Local Law 97. 100% of our portfolio is contracted for renewable wind electricity as of January 2021. Finally, we maintain a series of management practices utilizing recycling of tenant and construction waste, recycled content carpets, low off-gassing paints and adhesives, “green” pest control and cleaning solutions and recycled paper products throughout our office portfolio. Robust Environmental Leadership. We are leaders in the environmental sustainability space. Our Chairman, President and CEO, Anthony E. Malkin, is the Chair of the Sustainability Policy Advisory Board of the Real Estate Roundtable and was appointed to the New York City Climate Mobilization Advisory Board for the implementation of Local Law 97, the sole landlord representative on the board. He is a Co-Chair of Local Law 97 Technical Pathways for Commercial Building Working Group. Our SVP and Director of Energy, Sustainability, and ESG, Dana Robbins Schneider, serves on the Local Law 97 Commercial Buildings Working Group, Board of Directors for Urban Green, REBNY Sustainability Committee, Real Estate Roundtable Sustainable Policy Advisory Committee, and is a LEED Fellow, member of the USGBC LEED Steering Committee, and NYSERDA Clean Fight final Judge. In 2020, we were the first commercial real estate portfolio in the Americas to achieve the WELL Health-Safety Rating for Facility Operations and Management from the International WELL Building Institute. The WELL Health-Safety Rating is an evidence-based, third-party verified rating for new and existing buildings focused on operational policies, maintenance protocols, emergency plans and stakeholder engagement strategies to help organizations prepare their spaces for re-entry in a post-COVID-19 environment. We participated in the GRESB Real Estate Assessment for the first time in 2020 and earned the highest possible GRESB 5 Star Rating and Green Star recognition, and a score of 88, an achievement that places us in the top 20% of all respondents. Our score is approximately 10 points higher than our peer group average and almost 20 points higher than the global GRESB Average. We also achieved an A rating, which is the highest possible score, on the GRESB Public Disclosure. GRESB is the leading ESG benchmark for real estate and infrastructure investments covering over 1,200 property companies, REITs, funds and development companies. Furthermore, we were named a Fitwel champion in 2020 with Fitwel certified properties that represent 6.7 million square feet or approximately 83% of our Manhattan properties. These Fitwel certifications were awarded to us for our leadership in health and sustainability achievements. Fitwel is a rigorous third-party healthy building certification system operated by the Center for Active Design. Fitwel was created as a joint initiative between the U.S. Centers for Disease Control and Prevention and the General Services Administration to set the industry standard for evidence- based strategies that promote positive health outcomes for building occupants and communities. 76% of the square feet in our portfolio is ENERGY STAR Certified. Our headquarters office is one of the charter Energy Star for Tenant certificants. Experienced and Committed Management Team with Proven Track Record. Our senior management team is highly regarded in the real estate community and has extensive relationships with a broad range of brokers, owners, tenants and lenders. We have developed relationships we believe enable us to both secure high credit-quality tenants on attractive terms, as well as provide us with potential acquisition opportunities. We have substantial in-house expertise and resources in asset and property management, leasing, marketing, acquisitions, construction, development and financing and a platform that is highly scalable. Members of our senior management team have worked in the real estate industry for an average of approximately 32 years with extensive experience in greater New York area real estate, through many economic cycles. We take an intensive, hands-on approach to the management of our portfolio and quality brand building. As of December 31, 2020, our named executive officers owned 12.7% of our common stock on a fully diluted basis (including shares of common stock and OP Units as to which Anthony E. Malkin, our Chairman, President and CEO, disclaims beneficial ownership except to the extent of his pecuniary interest therein), and therefore their interests are aligned with those of our securityholders and they are incentivized to maximize returns to our securityholders. Flexible Balance Sheet Provides Operating Runway and Ability to Take Advantage of Opportunities That May Arise. As of December 31, 2020, we had cash and cash equivalents of $526.7 million and our consolidated net debt represented 37.2% of enterprise value. We had total debt outstanding of $2.2 billion, with a weighted average interest rate of 3.91% and a weighted average maturity of 8.2 years. Additionally, we had $1.1 billion of available borrowing capacity under our unsecured revolving credit facility as of December 31, 2020. Our credit facility matures in August 2021 and has two six-month extension options, subject to certain conditions. As expected, we have begun a process to • • • 5 evaluate a potential recast or extension of the credit facility. Excluding principal amortization, none of our debt matures until November 2024. We continue to extend and ladder our debt maturities, increase our access to a variety of capital sources and maintain modest leverage and ample liquidity. Our flexible balance sheet provides operating runway to navigate the challenging market environment and the ability to take advantage of attractive investment opportunities that may arise. Business and Growth Strategies Our primary business objectives are to maximize cash flow and total returns to our shareholders and to increase the value of our properties through the pursuit of the following business and growth strategies: • • • Lease-up Vacant Redeveloped Space. To date, we have capitalized on the opportunity to capture the significant embedded, de-risked growth from repositioning of our Manhattan office portfolio. We have redeveloped 95% of the office and retail space in our Manhattan portfolio and have the opportunity to lease up 690,000 square feet of currently vacant redeveloped office and retail space, of which 258,000 square feet are pre-built suites that are ready for immediate tenant occupancy. We also expect to benefit from our price positioning, as our fully modernized portfolio offers energy efficiency, indoor environmental quality, services and amenities, and desirable locations near mass transit with rents substantially below new construction. We acknowledge that the COVID-19 pandemic has materially impacted office use with the majority of our tenants’ employees not at work in their offices. While we are constructive on the long-term importance of office use, we think that it will be several months before office use recommences and business return to the market to lease space at the same rate as in 2019. Pursue Attractive Acquisition and Redevelopment Opportunities. We have built a dedicated investment function with our hire of a Chief Investment Officer and a full acquisitions team to position us to take advantage of potential opportunities. Our flexible balance sheet, access to capital, expertise in redevelopment of existing property into modernized, fully amenitized, healthy buildings with energy efficiency and indoor environmental quality combined with our ability to offer operating partnership units in tax deferred acquisition transactions should give us significant flexibility in structuring and consummating acquisitions. For the foreseeable future, we intend to focus our acquisition strategy primarily on Manhattan office properties and, to a lesser extent, office and multi-tenanted retail and multi- family properties in densely populated communities in the greater New York metropolitan area and other markets we may identify in the future. We also believe there may be opportunities to acquire and reposition additional stand-alone retail spaces. We believe we can identify investment opportunities where we can achieve attractive returns on invested capital. Further, we have a development site, Metro Tower at the Stamford Transportation Center, which is adjacent to our Metro Center property, which we believe to be one of the premier office buildings in Connecticut. All zoning approvals have been obtained to allow development of an approximately 0.4 million rentable square foot office tower and garage. We intend to develop this site when we deem the appropriate combination of market and other conditions are in place. Proactively Manage Our Portfolio. We believe our proactive, service-intensive approach to asset and property management helps increase occupancy and rental rates. We utilize our comprehensive building management services and our strong commitment to tenant and broker relationships and satisfaction to negotiate attractive leasing deals and to attract high credit-quality tenants. We proactively manage our rent roll and maintain continuous communication with our tenants. We foster strong tenant relationships by being responsive to tenant needs. We do this through the amenities we provide, the quality of our buildings and services, our employee screening and training, energy efficiency initiatives, and preventative maintenance and prompt repairs. Our attention to detail is integral to serving our clients and building our brand. Our properties have received numerous industry awards for their operational efficiency. We believe long-term tenant relationships will improve our operating results over time by reducing leasing, marketing and tenant improvement costs, as well as tenant turnover. We do extensive diligence on our tenants’ (current and prospective) balance sheets, businesses and business models to determine if we will establish long-term relationships in which they will both renew with us and expand over time. We have had 217 tenant expansions within our portfolio totaling over 1.9 million square feet since 2013. • Enhanced our Observatory Operations. In December 2019 we completed a comprehensive $160 million multi-year re-imagination and redevelopment of the entire observatory experience at the Empire State Building. The new observatory includes a dedicated visitor entrance on 34th Street, a 10,000 square foot 2nd floor tactile and digital immersive museum experience that celebrates the Empire State Building, from the moment it was conceived to its place in pop-culture today, and the newly renovated 102nd floor observatory that features floor-to-ceiling glass windows where guests can step right to the edge of the World’s Most Famous Building. The observatory’s recent renovations includes indoor environmental quality measures with MERV 13 filters, ventilation and an Atmos Air 6 bipolar ionization air purification system, which we have installed in select spaces, which neutralizes more than 99.9% of coronavirus particles, according to studies performed by Microchem Laboratory, one of the nation’s preeminent laboratories for testing EPA- and FDA-registered sanitizing products. Visitor feedback of the new experience and our safety protocols has been very positive. Leasing Our focus is to maintain a brand that tenants associate with a consistently high level of quality of services, healthy buildings, amenities, maintenance, and tenant installations, with high performance design guidelines for energy efficiency and indoor environmental quality, and long term financial stability. Through our commitment to brokers, we have developed long- term relationships that focus on negotiating attractive transactions with high credit-quality tenants. We proactively manage and cultivate our industry relationships and make the most senior members of our management team available to our constituencies. We believe that our consistent, open dialogue with our tenants and brokers enables us to maximize our results. Our focus on performance and long-term perspective allows us to concentrate on the ongoing management of our portfolio, while seeking opportunities for growth in the future. Property Management We protect our investments by regularly monitoring our properties, performing routine preventive maintenance, and implementing capital improvement programs in connection with property redevelopment and life cycle replacement of equipment and systems. We presently self-manage all of our properties. We proactively manage our properties and rent rolls to (i) aggregate smaller demised spaces to create large blocks of vacant space in order to attract high credit-quality tenants at higher rental rates, and (ii) create efficient, modern, pre-built offices that can be rented through several lease cycles and attract high credit-quality tenants. We aggressively manage and control operating expenses at all of our properties. In addition, we have made energy efficiency retrofitting and sustainability a portfolio-wide initiative driven by economic return. We pass on cost savings achieved by such improvements to our tenants through lower utility costs and reduced operating expense escalations. We believe these initiatives make our properties more desirable to a broader tenant base than the properties of our competitors. Business Segments Our reportable segments consist of a real estate segment and an observatory segment. Our real estate segment includes all activities related to the ownership, management, operation, acquisition, repositioning and disposition of our real estate assets. Our observatory segment operates the 86th and 102nd floor observatories at the Empire State Building. These segments are managed separately because each business requires different support infrastructure, provides different services and has dissimilar economic characteristics such as, investments needed, stream of revenues and marketing strategies. We account for intersegment sales and rent as if the sales or rent were to third parties at current market prices. This intersegment rent is eliminated upon consolidation. For more information about our segments, refer to “Financial Statements-Note 12-Segment Reporting” in this Annual Report on Form 10-K. Regulation General The properties in our portfolio are subject to various laws, ordinances and regulations, including regulations relating to common areas. We believe each of the existing properties has the necessary permits and approvals to operate its business. Americans with Disabilities Act Our properties must comply with Title III of the Americans with Disabilities Act, or ("ADA"), to the extent that such properties are “public accommodations” as defined by the ADA. The ADA may require removal of structural barriers to access by persons with disabilities in certain public areas of our properties where such removal is readily achievable. We believe the existing properties are in substantial compliance with the ADA and that we will not be required to make substantial capital expenditures to address the requirements of the ADA. However, noncompliance with the ADA could result in imposition of fines or an award of damages to private litigants. The obligation to make readily achievable accommodations is an ongoing one, and we will continue to assess our properties and to make alterations as appropriate in this respect. 7 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, without regard to 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. 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 fueling, 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. Soil contamination has been identified at 69-97 Main Street in Westport, Connecticut. The affected soils are more than four feet below the ground surface. An Environmental Land Use Restriction has been imposed on this site to ensure the soil is not exposed, excavated or disturbed such that it could create a risk of migration of pollutants or a potential hazard to human health or the environment. While the contamination is currently contained, the potential resale value of this property and our ability to finance or refinance this property in the future may be adversely affected as a result of such contamination. In addition, pursuant to the Environmental Land Use Restriction, plans for the redevelopment of the property would be subject to the review of the Town of Westport, Connecticut among other conditions. The property situated at 500 Mamaroneck Avenue in Harrison, New York was the subject of a voluntary remedial action work cleanup plan performed by the former owner following its conveyance of title to the present owners under an agreement with the New York State Department of Environmental Conservation, or ("NYDEC"). As a condition to the issuance of a “no further action” letter, NYDEC required that certain restrictive and affirmative covenants be recorded against the subject property. In substantial part, these include prohibition against construction that would disturb the soil cap isolating certain contaminated subsurface soil, limiting the use of such property to commercial uses, implementing engineering controls to assure that improvements be kept in good condition, not using ground water at the site for potable purposes without treatment, implementing safety procedures for workers to follow excavating at the site to protect their health and safety and filing an annual certification that the controls implemented in accordance with the voluntary remedial action work cleanup plan remain in place. Furthermore, a substantial portion of the site that had been substantially unimproved prior to acquisition may not be further developed. In addition, our properties are subject to various federal, state and local environmental and health and safety laws and regulations. Noncompliance with these environmental and health and safety 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 or may otherwise materially and adversely affect our operations, or those of our tenants, which could in turn have a material adverse effect on us. 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. 8 As the owner or operator of real property, we may also incur liability based on various building conditions. For example, buildings and other structures on properties that we currently own or operate or those we acquire or operate in the future contain, may contain, or may have contained, asbestos-containing material, or 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. In addition, 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. Insurance We carry comprehensive liability, fire, extended coverage, earthquake, terrorism and rental loss insurance covering all of our Manhattan properties and our greater New York metropolitan area properties under a blanket policy. We carry additional all-risk property and business insurance, which includes terrorism insurance, on the Empire State Building through ESRT Captive Insurance Company L.L.C., or ESRT Captive Insurance, our wholly owned captive insurance company. ESRT Captive Insurance covers terrorism insurance for $1.2 billion in losses in excess of $800 million per occurrence suffered by the Empire State Building, providing us with aggregate terrorism coverage of $2 billion at that property. ESRT Captive Insurance fully reinsures the 20% coinsurance under the Terrorism Risk Insurance Program Reauthorization Act of 2015 ("TRIPRA") and the difference between the TRIPRA captive deductible and policy deductible of $100,000 for non-Nuclear, Biological, Chemical and Radiological exposures. We purchased a $50 million limit of Nuclear, Biological, Chemical and Radiological ("NBCR") insurance in excess of a $1.0 million deductible in the commercial insurance market. ESRT Captive Insurance provides NBCR insurance with a limit of $1.95 billion in excess of the $50 million policy. As a result, we remain only liable for the 20% coinsurance under TRIPRA for NBCR exposures within ESRT Captive Insurance, as well as a deductible equal to 20% of ESRT Captive Insurance’s prior year’s premium. As long as we own ESRT Captive Insurance, we are responsible for ESRT Captive Insurance’s liquidity and capital resources, and ESRT Captive Insurance’s accounts are part of our consolidated financial statements. If we experience a loss and ESRT Captive Insurance is required to pay under its insurance policy, we would ultimately record the loss to the extent of its required payment. The policies described above cover certified terrorism losses as defined under the Terrorism Risk Insurance Act of 2002 (TRIA) and subsequent extensions. On December 20, 2019, the President of the United States signed into law TRIPRA act of 2019, which extended TRIA through December 31, 2027. TRIA provides for a system of shared public and private compensation for insured losses resulting from acts of terrorism. As a result, the certified terrorism coverage provided by ESRT Captive Insurance is eligible for 80% coinsurance provided by the United States Treasury in excess of a statutorily calculated deductible. ESRT Captive Insurance reinsures 100% of its 20% coinsurance for non-NBCR exposures. The 20% coinsurance on NBCR exposures is retained by ESRT Captive Insurance. Reinsurance contracts do not relieve ESRT Captive Insurance from its primary obligations to its policyholders. Additionally, failure of the various reinsurers to honor their obligations could result in significant losses to ESRT Captive Insurance. The reinsurance has been ceded to reinsurers approved by the State of Vermont. ESRT Captive Insurance continually evaluates the reinsurers’ financial condition by considering published financial stability ratings of the reinsurers and other factors. There can be no assurance that reinsurance will continue to be available to ESRT Captive Insurance to the same extent and at the same cost. ESRT Captive Insurance may choose in the future to reevaluate the use of reinsurance to increase or decrease the amounts of risk it cedes. In addition to insurance held through ESRT Captive Insurance described above, we carry terrorism insurance on all of our properties in an amount and with deductibles which we believe are commercially reasonable. 9 Our insurance policies include substantial self-insurance portions and significant deductibles and co-payments for certain events, and hurricanes in the United States have affected the availability and price of such insurance. We may discontinue certain insurance coverage on some or all of our properties in the future if the cost of premiums for any of these policies in our judgment exceeds the value of the coverage discounted for the risk of loss. Additionally, we do not carry insurance for certain losses, including, but not limited to, losses caused by war. Furthermore, business interruption insurance due to pandemic level or other public health events may not be readily available at commercially acceptable rates. In addition, while our title insurance policies insure for the current aggregate market value of our portfolio, we may decide to not increase our title insurance policies as the market value of our portfolio increases. Competition The leasing of real estate is highly competitive in Manhattan and the greater New York metropolitan market in which we operate. We compete with numerous acquirers, developers, owners and operators of commercial real estate, many of which own or may seek to acquire or develop properties similar to ours in the same markets in which our properties are located. The principal means of competition are rent charged, location, services provided and the nature and condition of the facility to be leased. In addition, we face competition from other real estate companies, including other REITs, private real estate funds, domestic and foreign financial institutions, life insurance companies, pension trusts, partnerships, individual investors and others, that may have greater financial resources or access to capital than we do or that are willing to acquire properties in transactions which are more highly leveraged or are less attractive from a financial viewpoint than we are willing to pursue. In addition, competition from new and existing observatories and/or broadcasting operations could have a negative impact on revenues from our observatory operations and/or broadcasting revenues. Adverse impacts on domestic and international travel and changes in foreign currency exchange rates may also decrease demand in the future, which could have a material adverse effect on our results of operations, financial condition and ability to make distributions to our securityholders. If our competitors offer space at rental rates below current market rates, below the rental rates we currently charge our tenants, in better locations within our markets or in higher quality facilities, we may lose potential tenants and we may be pressured to reduce our rental rates below those we currently charge in order to retain tenants when our tenants’ leases expire. Our Tax Status We elected to be taxed as a REIT and have operated in a manner that we believe allows us to qualify as a REIT for U.S. federal income tax purposes commencing with our taxable year ended December 31, 2013. We believe we have been organized in conformity with the requirements for qualification and taxation as a REIT under the Internal Revenue Code of 1986, as amended, the ("Code"), and that our intended manner of operation will enable us to meet the requirements for qualification and taxation as a REIT. So long as we qualify as a REIT, we generally will not be subject to U.S. federal income tax on our net taxable income that we distribute to our securityholders. If we fail to qualify as a REIT in any taxable year and do not qualify for certain statutory relief provisions, we will be subject to U.S. federal income tax at regular corporate rates and may be precluded from qualifying as a REIT for the subsequent four taxable years following the year during which we lost our REIT qualification. Even if we qualify for taxation as a REIT, we may be subject to certain U.S. federal, state and local taxes on our income or property. In order to qualify as a REIT, we must distribute to our securityholders, on an annual basis, at least 90% of our REIT taxable income, determined without regard to the deduction for distributions paid and excluding net capital gains. In addition, we will be subject to U.S. federal income tax at the generally applicable corporate tax rate to the extent that we distribute less than 100% of our net taxable income (including net capital gains) and will be subject to a 4% nondeductible excise tax on the amount by which our distributions in any calendar year are less than a minimum amount specified under U.S. federal income tax laws. In addition, to qualify as a REIT, we must ensure that we meet the REIT gross income tests annually and that at the end of each calendar quarter, at least 75% of the value of our total assets consists of cash, cash items, government securities and qualified REIT real estate assets, including certain mortgage loans and certain kinds of mortgage-backed securities. The remainder of our investment in securities (other than government securities, securities of corporations that are treated as Taxable REIT Subsidiaries ("TRSs") and qualified REIT real estate assets) generally cannot include more than 10% of the outstanding voting securities of any one issuer or more than 10% of the total value of the outstanding securities of any one issuer. In addition, in general, no more than 5% of the value of our assets (other than government securities and qualified real estate assets) can consist of the securities of any one issuer, and no more than 20% of the value of our total securities can be represented by securities of one or more TRSs. 10 Rents from real property are generally not qualifying income for purposes of the REIT gross income tests if the rent is treated as “related party rent.” Related party rent generally includes (i) any rent paid by a corporation if the REIT (or any person who owns 10% or more of the stock of the REIT by value) directly or indirectly owns 10% or more of the stock of the corporation by vote or value and (ii) rent paid by a partnership if the REIT (or any person who owns 10% or more of the stock of the REIT by value) directly or indirectly owns an interest of 10% or more in the assets or net profits of the partnership. Under an exception to this rule, related party rent is treated as qualifying income for purposes of the REIT gross income tests if it is paid by a TRS of the REIT and (i) at least 90% of the leased space in the relevant property is rented to persons other than either TRSs or other related parties of the REIT, and (ii) the amounts paid to the REIT as rent from real property are substantially comparable to the rents paid by unrelated tenants of the REIT for comparable space. Income from admissions to the Empire State Building observatory, and certain other income generated by the observatory, would not likely be qualifying income for purposes of the REIT gross income tests. We jointly elected with Observatory TRS, which is the current lessee and operator of the observatory and which is wholly owned by our operating partnership, for Observatory TRS to be treated as a TRS of ours for U.S. federal income tax purposes. Observatory TRS leases the Empire State Building observatory from the operating partnership pursuant to a lease that provides for fixed base rental payments and variable rental payments equal to certain percentages of Observatory TRS’s gross receipts from the operation of the observatory. Given the unique nature of the real estate comprising the observatory, we do not believe that there is any space in the Empire State Building or in the same geographic area as the Empire State Building that is likely to be considered sufficiently comparable to the observatory for the purpose of applying the exception to related party rent described above. We have received from the IRS a private letter ruling that the rent that our operating partnership receives from Observatory TRS pursuant to the lease of the Empire State Building observatory is qualifying income for purposes of the REIT gross income tests so long as such rent reflects the fair market rental value of the Empire State Building observatory as determined by an appraisal rendered by a qualified third party appraiser. In addition, our operating partnership has acquired various license agreements (i) granting certain third party broadcasters the right to use space on the tower on the top of the Empire State Building for certain broadcasting and other communication purposes and (ii) granting certain third party vendors the right to operate concession stands in the observatory. We have received from the IRS a private letter ruling that the license fees that our operating partnership receives under the license agreements described above constitute qualifying income for purposes of the REIT gross income tests. Inflation Substantially all of our leases provide for separate real estate tax and operating expense escalations. In addition, many of the leases provide for fixed base rent increases. We believe inflationary increases may be at least partially offset by the contractual rent increases and expense escalations described above. We do not believe inflation has had a material impact on our historical financial position or results of operations. Seasonality Our observatory business is subject to tourism trends and weather, and therefore does experience some seasonality. Historically, prior to the outbreak of COVID-19, approximately 16.0% to 18.0% of our annual observatory revenue was realized in the first quarter, 26.0% to 28.0% was realized in the second quarter, 31.0% to 33.0% was realized in the third quarter, and 23.0% to 25.0% was realized in the fourth quarter. We do not consider the balance of our business to be subject to material seasonal fluctuations. Human Capital Management As of December 31, 2020, the company employed 755 people, of whom approximately 543 are covered by collective bargaining agreements. We recognize that our success is realized through the attraction, retention, development, engagement and empowerment of the highly valued employees amongst our diverse pool of talent, and we endeavor to set our policies and practices accordingly. Diversity and Inclusion. We believe diverse perspectives and experiences enhance effective decision making and innovation. We strive to create a diverse, inclusive workplace where people can be authentic in their roles. We are proud of the strides we have made in the past two years in terms of enhancing the gender and ethnic diversity of our board and management team through the appointment of new directors and a new Chief Financial Officer. We also promoted our Senior Vice President and Director of Energy and Sustainability to Director of ESG with direct reporting lines to our Chairman, CEO, and President and our board. 11 Talent Acquisition and Retention. We know our future success depends upon our continued ability to attract, retain and motivate our valued employees. We offer what we believe to be generally competitive compensation and benefits. To reward and reinforce participation in the company’s outcomes, we also make equity grants to employees. For senior management, we grant such equity annually, with vesting contingent upon (a) the individual’s continuing service at the company and/or (b) the company’s performance against total shareholder return results. Other employees may receive shares of stock in the company on multi-year employment anniversaries. Employee Engagement. We regularly collect employee feedback to understand and improve the employee experience at our company. Training and Development. We believe continuous learning by our employees supports productivity, innovation and retention, as well as personal and professional growth for the individual employee. We invest in training, including certain programs which are mandatory for all employees and other programs which are voluntary and self-directed on platforms provided by the company. Health, Safety and Wellness. We have been recognized for leadership in indoor environmental quality, retrofit energy efficiency, and sustainability in the built environment. During the ongoing COVID-19 pandemic, we established protocols for building re-occupancy, including online screening for our staff, no-touch temperature checks for all entry to our buildings, and tests of indoor air quality and water systems. We have allowed working remotely where needed to accommodate health or childcare circumstances and to enhance social distancing in the workplace. We have provided and required personal protective equipment during the pandemic. Offices Our principal executive offices are located at 111 West 33rd Street, 12th floor, New York, New York 10120. In addition, we have six additional regional leasing and property management offices in Manhattan and the greater New York metropolitan area. Our current facilities are adequate for our present and future operations, although we may add regional offices, depending upon our future operations.

RISK FACTORS RISK FACTORS You should carefully consider these risk factors, together with all other information in this Annual Report on Form 10- K, including our consolidated financial statements and related notes, before you decide whether to retain or make an investment in our securities. The risks set out below are not the only risks we face. Additional risks and uncertainties that are not currently known to us or that we currently deem to be immaterial could have a material adverse effect on us and our REIT qualification). In such case, the trading price of our securities could decline, and you may lose all or part of your investment. Some statements in the following risk factors constitute forward-looking statements. See “Forward-Looking Statements.” Risks Related to Our Business and Properties Risks Related to the COVID-19 Pandemic The current COVID-19 pandemic has had, and any future public health crisis could have, serious adverse effects on our and our tenants’ businesses, operations and financial condition, and on local, national, and global economic activity, including by creating volatility and negative pressure in the financial markets. The COVID-19 pandemic has impacted the entire U.S., including New York and Connecticut where our properties are located. Measures taken by authorities to limit its impact, including quarantines, social distancing, restrictions on travel, business operations and construction, have affected, and continue to affect, adversely our and our tenants’ businesses, operations and financial condition. The foregoing impacts have reduced, and will likely continue to reduce, many of our tenants’ ability and/or willingness to pay rent, and court backlogs and obstacles from government moratoriums that abridge the enforcement of lease obligations also affect our ability to enforce payment. Certain tenants have made, and may continue to make, requests for rent deferral, rent abatement or lease termination, and/or have taken actions to challenge lease enforceability, defaulted on lease obligations or invoked insolvency protection, all of which have reduced, and may continue to reduce, our revenue. The scope and duration of the foregoing events are uncertain and unpredictable. In addition, as a result of such restrictions, we had to close the observatory to the public from March 16, 2020 to July 20, 2020, with the 102nd floor observation deck not reopening until August 24, 2020, and during such closure substantially all observatory revenue was discontinued. Since then, due to continued travel restrictions, visitor volume has lagged our expectations, and we cannot predict when we may achieve visitor volume comparable to 2019 when approximately 64% of our visitors were from other countries. During the fourth quarter of 2020, visitor volume declined by 93.8% compared to the corresponding period in 2019. Additionally, observatory revenue for 2020 was $29.1 million, a 77.4% decline compared to 2019. Moreover, real estate companies like us may be subject to claims from employees, tenants, vendors, visitors or the public that they were exposed to COVID-19 by our inadequate protective measures or were unnecessarily inconvenienced or damaged by our excessive protective measures. Additionally, the COVID-19 pandemic has had, and any future public health crisis could have, a material adverse effect on our operations, cash flows and financial condition due to, among other factors: adverse effect on our human capital management, as our employees, including senior management, remain subject to risk of illness, and certain employees continue to work remotely, which strains efficiencies and management oversight, cybersecurity, and morale; downturn in national and/or local economies, which impairs prospects for new and renewal leases, decreases demand and rental rates for office and retail space, and/or increases lease terminations and vacancy, all with an adverse impact on the value or market price of our assets; delays to and/or cancellations of our plans to execute capital projects, successfully or on the anticipated timeline or at the anticipated costs; potential impairment of our ability to pay down, refinance, restructure or extend our indebtedness as it becomes due, to comply with covenants in existing debt agreements, to borrow additional funds or to enter into new financings; volatility and downward pressure on the market price of our Class A common stock and publicly traded partnership units, which may also reduce our access to capital and/or our equity currency for new acquisitions; and reduction of our cash flows, which could negatively impact our ability to pay dividends and potentially affect our REIT qualification; and potential impairment of our ability to ensure business continuity if current plans are not effective or properly implemented during pandemic conditions. The rapid developments regarding the COVID-19 pandemic preclude reliable predictions as to its ultimate adverse impact, which largely arises from factors beyond our control. To the extent any of these risks and uncertainties adversely impact us in the ways described above or otherwise, they may also have the effect of heightening many of the other risks described under this section. 13 Risks Relating to Portfolio Concentration Our properties are geographically concentrated in New York and Connecticut, and adverse state or local economic or regulatory developments could have a material adverse effect on our operations, cash flow and financial condition. All of our properties are located within the greater New York metropolitan area, in particular midtown Manhattan (9 of 14 properties), and nearby markets in Fairfield County, Connecticut and Westchester County, New York. As a result, our business is dependent on the New York City economy in general and the market for office space in midtown Manhattan 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. We cannot guarantee that the greater New York City metropolitan market will grow or that underlying real estate fundamentals will be favorable to owners and operators of office or retail properties. The threat or occurrence of a terrorist event, particularly in New York City, may materially and adversely affect the value of our properties and our ability to generate cash flow. As a result of the threat, or occurrence, of a terrorist event, tenants in Manhattan and the greater New York metropolitan area may choose to relocate to less populated, lower-profile areas of the United States that are not as likely to be targets. This could trigger a decrease in the demand, occupancy and rental rates for space in Manhattan and the greater New York metropolitan area, which may materially affect the value of our properties and our ability to generate cash flow. Such negative consequences may be even more likely in a high-profile property like the Empire State Building and its Observatory. Additionally, a terrorist event could cause insurance premiums at certain of our properties to increase significantly, thus impairing net cash flows. We rely on six properties, in particular the Empire State Building and its Observatory, for a significant portion of our revenue. For the year ended December 31, 2020, six of our properties together accounted for approximately 74.8% of our portfolio’s rental revenues, with the Empire State Building individually accounting for approximately 32.8%. Our revenue and cash available for distribution would be materially and adversely affected if any of these six properties were materially damaged or destroyed or if a significant number of our tenants at these properties experienced financial strain that resulted in their failure to make timely rental payments, defaults under their leases or filing for bankruptcy. Additionally, for fiscal years ending December 31, 2018, 2019 and 2020, we derived approximately $131.2 million, $128.8 million and $29.1 million, respectively from the Empire State Building’s Observatory operations. Loss of revenue from the Observatory, as we have experienced in 2020 as a result of the COVID-19 pandemic, has had and can in the future have a material adverse impact on our total revenue and financial condition. Our five largest tenants represented approximately 14.3% of our total portfolio’s annualized rent as of December 31, 2020. As of December 31, 2020, our five largest tenants together represented 14.3% of our total portfolio’s annualized rent, with our largest tenant leasing an aggregate of 0.4 million rentable square feet of office space at one of our office properties, representing approximately 3.6% of our total portfolio rentable square feet and approximately 4.1% of our total portfolio annualized rent. Our significant tenants may experience financial strain that could potentially result in their failure to make timely rental payments, default under their leases or file for bankruptcy. In many cases, we have made substantial upfront investments in leases, through tenant improvement allowances and other concessions, as well as typical transaction costs (including professional fees and commissions) that we may not be able to recover. In the event of any tenant default, we may experience delays in enforcing our rights as landlord and may incur substantial costs in protecting our investment. Our financial condition could be materially adversely affected if any of our significant tenants were to suffer a downturn in their business, and/or become bankrupt or insolvent, default under their leases, fail to renew their leases or renew their leases on terms less favorable to us than their current terms. Risks Relating to the Real Estate Market 14 A sustained shift away from in-person work environments to remote work, increased use of a hoteling desk layout or a move towards a city hub and suburban spoke geographic model could have an adverse effect on the overall demand for office space. For our office tenants, limitations on in-person work environments caused by the COVID-19 pandemic could lead to a sustained shift away from in-person work environments, increased use of hoteling desk layout or a move to a city hub and suburban spoke geographic model, which would have an adverse effect on the overall demand for office space across our portfolio. These trends and the related effects may continue after the COVID-19 pandemic, which could make it difficult for us to renew or re-lease our properties at rental rates equal to or above historical rates, or at all. We could also incur more significant re-leasing costs, and the re-leasing process with respect to both anticipated and unanticipated vacancies could take longer. Adverse economic and geopolitical conditions impacting the industries of our tenants, in particular the retail industry, could cause reduced demand, rental rates and occupancy for our retail and office space. As of December 31, 2020, approximately 16.5% of our portfolio's annualized rent was comprised of retail tenants. In recent years, the retail industry has faced reductions in sales revenues and increased bankruptcies throughout the United States, which have been exacerbated by the COVID-19 pandemic. In addition, there has been a general trend toward consolidation in the retail industry, and a general consumer shift to online shopping has reduced demand for physical retail space and thus reduced the value of street level premises, which typically commanded the highest rental rates per square foot in office properties. Additionally, many of our tenants are in the financial and legal industries, in which significant job losses have occurred and may continue, which may decrease demand for our office space, rental rates and property values. These and other adverse conditions, including the COVID-19 pandemic, could adversely affect certain of our tenants, which could result in tenant defaults under leases due to bankruptcy, lack of liquidity, operational failures or other reasons, and in turn result in reduced demand, rental rates and occupancy for our retail and office space. The bankruptcy or insolvency of any tenant could result in the termination of such tenant’s lease and material losses to us. The occurrence of a tenant bankruptcy or insolvency could diminish or terminate the income we receive from that tenant. The COVID-19 pandemic has increased the number of tenant bankruptcies, where federal law may prohibit us from evicting such tenant, and such tenant may be authorized to reject and terminate its lease(s) with us. Any claims against such tenant for unpaid future rent would be subject to statutory limitations that would result in our receipt of rental revenues that are likely substantially lower than the contractually specified rent, and any claim we have for unpaid past rent may not be paid in full. Additionally, a large number of our tenants (measured by number of tenants as opposed to aggregate square footage) are smaller businesses that generally do not have the financial strength of larger corporate tenants. Smaller businesses generally experience a higher rate of failure than large businesses and may be at higher risk of bankruptcy. Tenant bankruptcies or insolvency could have a material adverse effect on our operations, cash flow and financial condition. Competition in the New York metropolitan area may impede our ability to attract or retain tenants or re-lease space. Our office properties are concentrated in highly developed areas of midtown Manhattan and densely populated metropolitan communities in Fairfield County and Westchester County. The leasing of real estate in the greater New York metropolitan area is highly competitive. The principal means of competition are rent rates, location, services and the nature and condition of the premises. We directly compete with lessors and developers of similar space in the areas where our properties are located as well as properties in adjacent submarkets. Additionally, we have seen increased competition from lessors that have converted traditional office space to flex space and offer additional amenities. Such increased competition (through potentially newer or better equipped or located properties) could have a material adverse effect on our ability to lease or re-lease office space at our properties, and on the effective rents we are able to charge. We may be unable to renew leases or re-lease vacant space on favorable terms or at all as leases expire. As of December 31, 2020, we had approximately 1.1 million rentable square feet of vacant space (excluding leases signed but not yet commenced). In addition, leases representing 6.4% and 5.5% of the square footage of the properties in our portfolio will expire in 2021 and 2022, respectively (including month-to-month leases). We cannot be assured that expiring leases will be renewed or that our properties will be re-leased at net effective rental rates at or above the current average. 15 We may be required to make rent or other concessions and/or significant capital expenditures to improve our properties in order to retain and attract tenants. 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, we may have to make significant capital or other expenditures in order to retain tenants whose leases expire and to attract new tenants. If we are unable to do so or capital is otherwise unavailable, we may be unable to make the required expenditures. This could result in non-renewals by tenants upon expiration of their leases and our vacant space remaining untenanted, which could have a material adverse effect on our operations, cash flow and financial condition. Risks Relating to Our Properties We face various risks related to our ground leases, including those arising from breach, expiration and eminent domain proceedings, and we have no permanent economic interest in the land or improvements at such properties. Our interests in three of our commercial office properties, 1350 Broadway, 111 West 33rd Street and 1400 Broadway, are ground leases (i.e., long-term leaseholds of the land and the improvements), rather than a fee interest in the land and the improvements. Pursuant to these ground leases, we, as tenant, perform the functions traditionally performed by owners: collect rent from our subtenants, maintain the properties and pay related expenses. We do not have a right to acquire the fee interests in these properties. The ground leases, including unilateral extension rights available to us, expire on July 31, 2050 for 1350 Broadway, December 31, 2063 for 1400 Broadway and June 10, 2077 for 111 West 33rd Street. If we are found to be in breach of these ground leases, the fee owner of the properties may terminate the leases, and we could lose the right to use the properties. In addition, unless we purchase the underlying fee interest in these properties or extend the terms of the ground leases, we will lose our right to operate these properties, or continue to operate them at much lower profitability. Additionally, we will not share in any increase in value of the land or improvements and will not receive any revenue from the property beyond the term of our ground leases. If the government acquires the properties under its eminent domain power, we would only be entitled to a portion of any compensation awarded. It may be more expensive for us to renew our ground leases, to the extent renewal is available at all. We are exposed to risks associated with property development. We have engaged, and continue to engage, in development activities with respect to our properties. We own entitled land at the Transportation Center in Stamford, Connecticut that can support the development of an approximately 0.4 million rentable square foot office building and garage. Development subjects us to risks beyond our control, which could have a material adverse effect on our financial condition, including, without limitation, the availability and pricing of financing; availability and timing of zoning and other approvals; occupancy rates and rents; construction costs and delays (whether due to weather, labor conditions, material shortages or otherwise), and timely lease-up. We will fail to recover expenses and management time already incurred if we abandon development. We may not be able to control our operating costs, or our expenses may remain constant or increase even if income from our properties decreases. Certain costs associated with real estate investment, such as real estate taxes, insurance and maintenance costs, generally are not reduced when a property is not fully occupied, rental rates decrease or other circumstances cause a reduction in income. The terms of our leases may also limit our ability to charge our tenants for all or a portion of these expenses. Risks Related to Our Non-Real Estate Operations The Observatory operations at the Empire State Building are not traditional real estate operations, and may be negatively impacted by competition, adverse weather, and changes in tourist trends caused by public health crises, including COVID-19 pandemic, among other factors. For fiscal years ending December 31, 2018, 2019 and 2020, we derived approximately $131.2 million, $128.8 million and $29.1 million from our Observatory operations. Our revenues declined significantly in 2020, as a result of the pandemic 16 and government mandated closures and a slow ramp-up in visitor volume after reopening in July 2020, in large part due to travel restrictions. We cannot predict when, if at all, our Observatory revenues will return to pre-COVID-19 levels. Any future health or other economic crisis could negatively impact tourist trends and visitor demand for our Observatory, which could have a material adverse effect on our business. We are also susceptible to reductions in visitor demand due to adverse weather. We compete against existing observatories in New York City at the World Trade Center, Rockefeller Center and Hudson Yards, and an additional observatory is expected at One Vanderbilt in 2022, all of which may divert visitors and negatively impact our revenue. The broadcasting operations at the Empire State Building are not traditional real estate operations, and competition and changes in the broadcasting of signals over air may subject us to additional risks. The Empire State Building and its broadcasting mast provide radio and data communications services and support delivery of broadcasting signals to cable and satellite systems and television and radio receivers. We license the use of the broadcasting mast to third party television and radio broadcasters. During the year ended December 31, 2020, we derived approximately $13.5 million of revenue (excluding tenant reimbursement income) from such broadcasting licenses and related leases, as compared with about $21 million at its peak a few years ago. Competition from other broadcasting operations has had a negative impact on revenues from our broadcasting operations, 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. Recent government regulations may materially and adversely affect our broadcast revenue by reducing the demand for broadcast licenses through making more spectrum available for wireless broadband service providers. The impairment of a significant portion of goodwill could negatively affect our reported financial condition. Our balance sheet includes goodwill of approximately $491.5 million at December 31, 2020, consisting primarily of goodwill associated with our acquisition of the controlling interest in Empire State Building Company L.L.C. and 501 Seventh Avenue Associates L.L.C. On an annual basis and whenever circumstances indicate the carrying value or goodwill may be impaired, we are required to assess any such impairment and charge to operating earnings the resulting non-cash impairment. The closure of our Observatory due to the pandemic caused us during the second, third and fourth quarters of 2020 to perform such an assessment using a third-party valuation consulting firm, and though we determined no impairment was necessary then, we will continue such assessments when appropriate. See “Financial Statements – Note 3 – Deferred Costs, Acquired Lease Intangibles and Goodwill.” An impairment could have a material adverse effect on our reported earnings. Risks Relating to Acquisitions and Dispositions We may be unable to identify and successfully complete acquisitions, and even if acquisitions are identified and completed, they may expose us to additional risks. Our current portfolio consists entirely of properties that we acquired in connection with the formation transactions that we completed in connection with our IPO. We plan to acquire new properties as we are presented with attractive opportunities, but we may face significant competition from other investors, particularly private investors who can incur more leverage. We may incur significant costs and divert management attention in connection with potential acquisitions, including ones that we are unable to complete. If we successfully identify an acquisition target and close the transaction, we may spend more than budgeted to make necessary improvements to the relevant properties and be exposed to unknown liabilities, such as environmental contamination or claims from former tenants, vendors or employees. Additionally, acquired properties may be located in new markets where we may lack market knowledge or business relationships or familiarity with local laws. We may acquire properties through tax deferred contribution transactions, which could result in securityholder dilution and limit our ability to sell such assets. In the future we may acquire properties through tax deferred contribution transactions in exchange for partnership interests in our operating partnership, which may result in dilution to securityholders, reduction of tax depreciation we could deduct over the tax life of the acquired properties (as compared with an acquisition paid in cash), and requirements to protect the contributors’ tax deferral through restrictions on our disposition of the acquired properties and/or allocation of partnership debt to the contributors to maintain their tax bases. These restrictions could limit our ability to sell an asset at a time, or on terms, that would be favorable absent such restrictions. If we are unable to sell, dispose of or refinance one or more properties in the future, we may be unable to realize our investment objectives. 17 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 Internal Revenue Code of 1986, as amended (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. If a transaction intended to qualify as a Section 1031 Exchange is later determined to be taxable, we may face adverse tax consequences, and if the laws applicable to such transactions are amended or repealed, we may not be able to dispose of properties on a tax deferred basis. From time to time we may dispose of properties in transactions that are intended to qualify as Section 1031 Exchanges. It is possible that any such qualification could be successfully challenged and determined to be currently taxable. This could increase the taxable dividend income to our stockholders, require us to file amended tax returns and require us to pay additional dividends or, in lieu of that, corporate income tax, possibly including interest and penalties. If the underlying property is a dealer property, our gains from sale would be subject to a 100% tax. The current administration has also indicated its intention to modify Section 1031 in a manner that could make it more difficult or impossible for us to dispose of properties on a tax deferred basis. Risks Relating to Our Indebtedness and Liquidity The phase-out, replacement or unavailability of LIBOR could affect interest rates under our revolving credit facility, as well as our ability to obtain future debt financing on favorable terms. We are subject to interest rate risk under our revolving credit facility and related term loan, which use U.S. Dollar (“USD”) LIBOR to establish the interest rate. In July 2017, the Financial Conduct Authority (the regulatory authority over LIBOR) stated that it would phase out LIBOR as a benchmark. In November 2020, the Federal Reserve Board announced that banks must stop writing new USD LIBOR contracts by the end of 2021 and that, no later than June 30, 2023, when USD LIBOR will no longer be published, market participants should amend legacy contracts to use the Secured Overnight Financing Rate (“SOFR”) or another alterative reference rate. Our debt facilities provide a mechanism to set an alternative rate of interest, but no such amendment has yet been made. Due to the phase-out of USD LIBOR and transition to SOFR, financial markets may be disrupted. Such disruption in the financial markets could have a material adverse effect on our financial condition and adversely affect our ability to obtain future debt on favorable terms. Our debt and related limitations in our loan documents could adversely affect us. As of December 31, 2020, we had total debt outstanding of approximately $2.2 billion and total mortgages of approximately $786.9 million with no maturity before 2024. See “Financial Statements – Note 4 – Debt” for required payments of our indebtedness. 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 related 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. We may fail to hedge interest rates effectively. If any one of these events were to occur, our operations, cash flow, financial condition, and ability to service debt and to make distributions could be adversely affected. Our debt includes restrictions on our financial and operational flexibility and distributions. Our debt instruments may restrict our financial and operational flexibility. For example, our lockbox and cash management agreements 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. The partnership agreement of our operating partnership 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” and “Private Perpetual Preferred Units.” 18 Mortgages expose us to foreclosure and loss of our investment in a mortgaged property. Mortgage and other secured debt increases our risk of property losses because defaults may result in foreclosure. For tax purposes, a foreclosure generally is treated as a sale of the property for a purchase price equal to the outstanding debt. If such debt exceeds our tax basis in the property, we will recognize taxable income on foreclosure, but not receive any cash. Foreclosures could also trigger our obligations under tax protection agreements with certain legacy investors to indemnify them for certain taxes upon sale of specific properties where they had embedded phantom taxable income (or the failure to maintain certain levels of indebtedness available for them to guarantee). See “Financial Statements – Note 10 – Related Party Transactions – Tax Protection Agreements.” High mortgage rates and/or unavailability of mortgage debt may make it difficult for us to finance or refinance properties, which could reduce the number of properties we can acquire, our net income and the amount of cash distributions we can make. If mortgage debt is unavailable at reasonable rates, we may not be able to finance the purchase of properties. If we place mortgage debt on properties, we may be unable to refinance the properties when the loans become due comparable terms. This may result in reduced cash flows and hinder our ability to make distributions, and to raise more capital by issuing more stock or by borrowing more money. In addition, to the extent we are unable to refinance loans, we will have fewer debt guarantee opportunities available to offer under our tax protection agreements, which could trigger our related indemnification obligation. Our growth depends on external sources of capital that are outside of our control. 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. 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. Risks Relating to Disaster Recovery and Business Continuity Natural disasters and climate change could adversely impact our area and business. Our properties are concentrated in the New York metropolitan area. Natural disasters, including earthquakes, storms, storm surges, tornados, floods and hurricanes, could cause significant damage to our properties and the surrounding area. Climate change, including rising sea levels and extreme temperature fluctuations, could adversely impact the metropolitan areas in which we operate. These conditions could result in declining demand for office or retail space in our buildings, compromise our ability to operate the buildings, make insurance less affordable or available, and increase the cost of energy 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. Some of our potential losses may not be covered by insurance. Our insurance may not be adequate to cover all losses to which we are subject. Business interruption insurance generally does not include coverage for damages from a pandemic, although certain third parties have claimed such coverage in litigation, which we continue to monitor. In addition, our insurance policies include substantial self-insurance and deductibles and co-payments for certain events. See Part I, Item 1, “Business – Insurance.” If we experience a loss that is uninsured or exceeds our policy limits, we could incur significant costs and loss of capital or property. If the damaged property is subject to recourse debt, we would continue to be liable for the debt, regardless of the property condition. Our debt instruments contain customary covenants to maintain insurance, including terrorism insurance. While we do not believe it is likely, our lenders or ground lessors could take the position that a total or partial exclusion for losses due to terrorist acts is a breach that would accelerate debt repayment or recapture ground lease positions. In addition, if they were to prevail in requiring additional coverage, it could result in substantially higher premiums. In the future, we may be unable to obtain insurance with insurers that satisfy the rating requirements in our agreements, which could give rise to a default under such agreements and/or impair our ability to refinance. 19 We may incur significant costs to comply with environmental laws, and environmental contamination may impair our ability to lease and/or sell real estate. Our properties are subject to various laws and regulations concerning protection of the environment, including air and water quality, hazardous substances, and health and safety. Some of our properties, or adjacent properties, have previously been used by former owners or tenants for commercial or industrial activities (e.g., gas stations, underground storage tanks, and dry cleaners), and a portion of the Metro Tower site is currently used for automobile parking and fueling, which may release hazardous substances. The presence of contamination or the failure to remediate contamination at any of our properties may subject us to fines and impair our ability to sell, lease or finance them. If contamination is discovered on our properties, environmental laws may restrict use or operations. For example, our property at 69-97 Main Street in Westport, Connecticut is subject to restrictions on the use, occupancy and development of the property, which may impair our ability to sell, lease or finance this property. Other laws and regulations govern indoor and outdoor air and water quality including abatement or removal of asbestos-containing materials, lead paint, and electrical equipment containing polychlorinated biphenyls (PCBs). We are also subject to risks associated with human exposure to chemical or biological contaminants such as molds, pollens, viruses and bacteria, which may cause adverse health effects. Our predecessors may be subject to similar liabilities for past activities. We could incur fines and be liable for the costs of remedial action with respect to the foregoing. 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 may become subject to new compliance requirements and/or new costs or taxes associated with natural resource or energy usage (such as a “carbon tax”), which could increase our operating costs. See Part I, Item 1, “Business - Environmental Matters.” Risks Relating to Human Capital Management The departure of any of our key personnel could materially and adversely affect us. Our success depends on the efforts of key personnel, particularly Anthony E. Malkin, our Chairman, President and Chief Executive Officer, whose leadership and national industry reputation benefits us in many ways. He has led the acquisition, operation and repositioning of our assets for more than two decades. Other members of our senior management team also have strong industry reputations and experience, which aid us in attracting, identifying and taking advantage of opportunities. The loss of the services of one or more members of our senior management team could materially and adversely affect us. Our Chairman, President and Chief Executive Officer has outside business interests that take his time and attention away from us, which could materially and adversely affect us. Under his employment agreement, Mr. Malkin has agreed to (a) devote a majority of his business time and attention to our business and (b) during, and for a time after, his employment with us to refrain from competition with us. Mr. Malkin is also permitted to devote time to his other investments to the extent such activities do not materially interfere with the performance of his duties to us. He owns interests in properties and businesses that were not contributed to us in the formation transactions, some of which are now managed by our company. See “Financial Statements – Note 10 – Related Party Transactions – Excluded Properties and Businesses.” In some cases, Mr. Malkin or his affiliates may have management and fiduciary obligations that could conflict with his responsibilities to our company. We may choose to moderate or omit enforcement of our rights under this agreement to maintain our relationship with him given his knowledge of our business, relationships with our customers, and significant equity ownership in us, and this could have a material adverse effect on our business. Our failure to maintain satisfactory labor relations could materially and adversely affect us. As of December 31, 2020, we have collective bargaining agreements that cover 543 employees, or 72% of our workforce, that service all of our office properties. 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. Risks Relating to Legal Compliance and Cybersecurity 20 We face risks associated with our tenants being designated “Prohibited Persons” by OFAC and similar requirements. The Office of Foreign Assets Control of the U. S. Department of the Treasury (“OFAC”) maintains a list of persons designated as terrorists or who are otherwise blocked or banned (“Prohibited Persons”) from conducting business or engaging in transactions in the U. S. and thereby restricts our doing business with such persons. In addition, our leases, loans and other agreements may require us to comply with OFAC and related requirements, and any failure to do so may result in a breach of such agreements. If a tenant or other party with whom we conduct business is designated a Prohibited Person, we may be required to terminate the arrangement or face penalties. Any such termination could result in a loss of revenue or otherwise negatively affect our business. We may incur significant costs complying with the ADA and similar laws. Under the Americans with Disabilities Act of 1990 (the “ADA”), all public accommodations must meet federal requirements related to access and use by disabled persons. We would be required to incur costs to bring any non-compliant property into compliance and could be required to make modifications to our properties upon any renovation, all of which could involve substantial costs and material adverse effect on our financial conditions. We may become subject to litigation, which could have a material adverse effect on our financial condition. In the past we have been, and in the future we may become, subject to litigation, including claims relating to our operations, offerings, and otherwise in the ordinary course of business. Some of these claims may result in significant defense costs and potentially significant judgments against us, some of which are not, or cannot be, insured against. We generally intend to defend ourselves vigorously; however, we cannot be certain of the ultimate outcomes of any claims that may arise in the future. Certain litigation or its resolution may affect the availability or cost of our insurance coverage, which could adversely impact our financial condition, expose us to increased uninsured risks, and/or adversely impact our ability to attract officers and directors. See “Financial Statements – Note 8 – Commitments and Contingencies.” Cyberattacks and any failure to comply with related laws could negatively impact us. We rely extensively on technology, both internal and outsourced, to process transactions and manage our business, so our business is increasingly at risk from cyberattacks that continue to increase in number, intensity and sophistication. These could include internal and external attempts to gain unauthorized access to our data and computer systems to, disrupt operations, or steal confidential information. We employ a number of controls to prevent and mitigate these threats; but there is no guarantee such measures will be successful. A cyberattack could compromise the confidential information of our employees, tenants, customers and vendors, and disrupt our business operations and relationships. Any compromise of our security could also result in a violation of applicable privacy and other laws, with significant damage to our legal and financial condition, our reputation, our business, our records, and confidence of our business relationships. New laws and regulations on these subjects pose increasingly complex compliance challenges and costs across multiple jurisdictions. Risks Related to Our Organization and Structure If our board revokes our REIT election or we fail to remain qualified as a REIT, we may be required to pay U.S. federal income taxes at corporate rates, which may cause adverse consequences to our securityholders. Although we believe that we will remain organized and will continue to operate so as to qualify as a REIT for U.S. federal income tax purposes, our board may revoke our REIT election, without stockholder approval, if the board determines that it is no longer in our best interest to continue to qualify as a REIT or we may fail to remain so qualified. Qualifications are governed by highly technical and complex provisions of the Code for which there are only limited judicial or administrative interpretations and depend on various facts and circumstances that are not entirely within our 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. If, with respect to any taxable year, we fail to maintain our qualification as a REIT and do not qualify under statutory relief provisions, we could not deduct distributions to shareholders in computing our taxable income and would have to pay U.S. federal income tax on our taxable income at regular corporate rates and thus reduce funds available for distribution and debt service, and we would not be required to make distributions until we re-qualified as a REIT which would not be permitted for the four taxable years following our disqualification, unless we gained relief under relevant statutory provisions. Refer to Part I, Item 1, “Business – Our Tax Status” for more information. 21 Failure to qualify as a domestically controlled REIT could subject our non-U.S. securityholders to adverse U.S. federal income tax consequences. While we intend to continue to qualify as a "domestically controlled" REIT for purposes of the Foreign Investment in Real Property Tax Act of 1980, we cannot assure that result, as our Class A common stock is publicly traded, QIA (a non-U.S. holder) owns approximately 17.53% of our common stock and other non-U.S. holders may now or in the future hold additional shares. If we were to fail to qualify, gain realized by a foreign investor (other than a “qualified shareholder”, a “qualified foreign pension fund” or a “qualified controlled entity”) on a sale of our common stock would be subject to FIRPTA unless (a) our common stock was traded on an established securities market and the foreign investor did not at any time during a specific testing period directly or indirectly own more than 10% of the value of our outstanding common stock, or (b) another exemption from FIRPTA were applicable. Complying with the REIT requirements may cause us to forego and/or liquidate otherwise attractive investments. If we fail to comply with the income and asset requirements for a REIT at the end of any calendar quarter, we must correct the failure within 30 days after the end of the calendar quarter or qualify for certain other statutory relief provisions to avoid losing our REIT qualification and suffering adverse tax consequences. Refer to Part I, Item 1, “Business – Our Tax Status” for more information. In order to satisfy the gross income or asset tests applicable to REITs under the Code, we may be required to forego investments that we otherwise would make or liquidate otherwise attractive investments. This could have the effect of reducing our income and amounts available for distribution. The REIT distribution requirements could require us to borrow funds during unfavorable market conditions or subject us to tax, which would reduce the cash available for distribution to our securityholders. We intend to distribute our net income to our securityholders in a manner intended to satisfy the REIT 90% distribution requirement and to avoid U.S. federal income tax and the 4% nondeductible excise tax. Refer to Part I, Item 1, “Business – Our Tax Status” for more information. 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 Risk Factors section. In addition, our taxable income may exceed our net income as determined by GAAP because, for example, realized capital losses will be deducted in determining our GAAP net income, but may not be deductible in computing our taxable income. In addition, we may incur nondeductible capital expenditures or be required to make debt or amortization payments or the effect of limitations on interest (subject to an exception for an electing real property trade or business) and net operating loss deductibility under the current law could cause our taxable income to exceed our net income as determined by GAAP. As a result of the foregoing, we may generate less cash flow than taxable income in a particular year, and we may incur U.S. federal income tax and the 4% nondeductible excise tax on that income if we do not distribute such income to securityholders in that year. In that event, 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 such REIT requirements and avoid such taxes. If our operating partnership is treated as a corporation for U.S. federal income tax purposes, we will cease to qualify as a REIT. In order for our publicly traded operating partnership to be treated and taxed as a partnership for U.S. federal income tax purposes, 90% or more of its gross income must consist of certain passive type income such as rent, interest, dividends, etc. If our operating partnership were to fail to meet the gross income requirement for treating a publicly traded partnership as a partnership or the IRS were to successfully challenge our operating partnership’s status as a partnership, we would fail to meet the gross income tests and certain of the asset tests applicable to REITs and, therefore, cease to qualify as a REIT and our operating partnership would become subject to U.S. federal, state and local income tax. The payment by our operating partnership of income tax would reduce significantly the amount of cash available to our operating partnership to satisfy obligations to make principal and interest payments on its debt and to make distributions to its partners, including us. If we are unable to continue to lease the Empire State Building observatory to a TRS or to maintain our broadcast licenses, in each case in a manner consistent with the IRS ruling that we have received, we would be required to restructure our operations in a manner that could adversely affect the value of our stock. We rely upon private letter rulings from the IRS that income from our Observatory and broadcast facilities 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 22 always be able to do so. If we were not able to treat the rent that our operating partnership receives from Observatory TRS as qualifying income for purposes of the REIT gross income tests, we would be required to restructure the manner in which 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 the license fees that our operating partnership will receive from the license agreements described above as qualifying income for purposes of the REIT gross income tests, we would be required to enter into the license agreements described above 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 us to fail to qualify as a REIT. Although our use of TRSs may partially mitigate the impact of meeting certain requirements necessary to maintain our qualification as a REIT, there are limits on our ability to own TRSs, and a failure to comply with the limits would jeopardize our REIT qualification and may result in the application of a 100% excise tax. A REIT may own up to 100% of the stock of one or more TRSs. A TRS may hold assets and earn income that would not be qualifying assets or income if held or earned directly by a REIT. A corporation of which a TRS directly or indirectly owns more than 35% of the voting power or value of the stock will automatically be treated as a TRS. Overall, no more than 20% of the value of a REIT’s assets may consist of securities of one or more TRSs. The rules also impose a 100% excise tax on certain transactions between a TRS and its parent REIT that are not conducted on an arm’s-length basis. We have jointly elected with each of Observatory TRS and Holding TRS, for each of Observatory TRS and Holding TRS to be treated as a TRS under the Code for U.S. federal income tax purposes in 2013. Observatory TRS, Holding TRS, and any other TRSs that we form pay U.S. federal, state and local income tax on their taxable income, and their after-tax net income is available for distribution to us but is not required to be distributed to us unless necessary to maintain our REIT qualification. Although we monitor the aggregate value of the securities of such TRSs and intend to conduct our affairs so that such securities will represent less than 20% of the value of our total assets at the end of each calendar quarter, there can be no assurance that we will be able to comply with the TRS limitation in all market conditions. There remains uncertainty as to how partnership tax audits will be applied. In the case of an audit for taxable years beginning after December 31, 2017, our operating partnership and any subsidiary partnership may be required to pay the hypothetical increase in partner-level taxes (including interest and penalties) resulting from an adjustment of partnership tax items on audit or in other tax proceedings, unless the partnership elects an alternative method under which the taxes resulting from the adjustment (and interest and penalties) are assessed at the partner level. In addition, Treasury Regulations provide that a partner that is a REIT may be able to use deficiency dividend procedures with respect to such adjustments. Many uncertainties remain as to the application of these rules, and the impact they will have on us. However, it is possible, that partnerships in which we invest may be subject to U.S. federal income tax, interest and penalties in the event of a U.S. federal income tax audit as a result of these law changes. Our state and local taxes could increase due to property tax rate changes, reassessment and/or changes in state and local tax laws, which could materially and adversely affect us. We are required to pay state and local taxes on our properties. From time to time changes in state and local tax laws or regulations are enacted, which may result in an increase in our tax liability. A shortfall in tax revenues for states and municipalities in which we operate may lead to an increase in the frequency and size of such changes. In particular, the federal government has recently limited the ability of individuals to deduct state and local taxes on their federal tax returns, potentially leading many high-tax states to make significant changes to their own state and local tax laws. In addition, the COVID-19 pandemic has left many state and local governments with reduced tax revenue, which may lead such governments to increase taxes or otherwise make significant changes to their state and local tax laws. If such changes occur, we may be required to pay additional taxes on our assets or income. The real property taxes on our properties may increase as property tax rates change or as our properties are assessed or reassessed by taxing authorities. Therefore, the amount of property taxes we pay in the future may increase substantially from what we have paid in the past. If the property taxes we pay increase, our financial condition could be materially and adversely affected. U.S. federal tax reform legislation now and in the future could affect REITs generally and the geographic markets in which we operate both positively and negatively, in ways that are difficult to anticipate. 23 The rules dealing with U.S. federal, state and local income taxation are constantly under review by persons involved in the legislative process and by the IRS and the U.S. Treasury Department. Changes to tax laws (which changes may have retroactive application) could adversely affect our securityholders or us. In recent years, many such changes have been made and changes are likely to continue to occur in the future. Pursuant to the formation transactions, Malkin Properties of Connecticut, Inc., a Connecticut corporation, or Malkin Properties CT, and Malkin Construction Corp., a Connecticut corporation, or Malkin Construction merged with and into a subsidiary of ours, with the subsidiary surviving, in a transaction that was intended to be treated as a reorganization under the Code. Each of Malkin Properties CT and Malkin Construction had previously elected to be treated as an S Corporation for U.S. federal income tax purposes under Section 1361 of the Code with respect to periods preceding our formation transactions. If either of Malkin Properties CT or Malkin Construction had failed to qualify as an S corporation with respect to periods preceding our formation transactions, we could have assumed material U.S. federal income tax liabilities in connection with the formation transactions and/or may be subject to certain other adverse tax consequences. In addition, to qualify as a REIT under these circumstances, we would be required to distribute, prior to the close of our first taxable year in which we elect to be taxed as a REIT under the Code, any earnings and profits of these entities to which we were deemed to succeed. No rulings from the IRS were requested and no opinions of counsel were rendered regarding the U.S. federal income tax treatment of any of Malkin Properties CT or Malkin Construction with respect to periods preceding our formation transactions. Accordingly, no assurance can be given that Malkin Properties CT or Malkin Construction qualified as an S corporation for U.S. federal income tax purposes during such periods, or that these entities did not have any other tax liabilities. In addition, Malkin Holdings LLC merged with a subsidiary of our operating partnership in the formation transactions, and as a result, we may have inherited any liabilities, including any tax liabilities, of Malkin Holdings LLC. Our tax protection agreements could limit our ability either to sell certain properties or to engage in a strategic transaction, or to reduce our level of indebtedness, which could materially and adversely affect us. In connection with the formation transactions, we entered into a tax protection agreement with certain Malkin family members, including Anthony E. Malkin and Peter L. Malkin, pursuant to which we have agreed to indemnify the Malkin Group and one additional third party investor in Metro Center, and in connection with our sale of a 9.9% fully diluted interest in our company to QIA in 2016, we agreed, subject to certain minimum thresholds and conditions, to indemnify QIA, in each case, against certain tax liabilities that may arise from certain property transactions. See “Financial Statements – Note 10 – Related Party Transactions – Excluded Properties and Businesses.” If we were to trigger such tax indemnification obligations, we would be required to pay the resulting tax consequences to the Malkin Group, the additional third party investor in Metro Center and/ or QIA, as applicable. These obligations may restrict our ability to engage in a strategic transaction, require us to maintain more or different debt, and/or inhibit our disposing of a property that we might judge to be otherwise be in the best interest of the securityholders. Holders of our Class B common stock have a significant vote in matters submitted to a vote of our securityholders. As part of our formation, we sought to give each contributing investor an option to hold equity interests which would allow such investor to vote on company matters in proportion to such investor’s economic ownership in the consolidated entity, whether such investor elected taxable Class A common stock or tax-deferred operating partnership units. Thus, the original investors were offered the opportunity to contribute their interests to us in exchange for a mix of one share of Class B common stock and 49 operating partnership units for each 50 operating partnership units to which an investor was otherwise entitled. Each outstanding share of Class B common stock, when accompanied by 49 operating partnership units, entitles the holder thereof to 50 votes on all matters on which Class A common securityholders are entitled to vote, including the election of directors. Holders of our Class B common stock may have interests that differ from holders of our Class A common stock and may accordingly vote in ways that may not be consistent with the interests of holders of our Class A common stock. This significant voting influence over certain matters may have the effect of delaying, preventing or deterring a change of control of our company, or could deprive holders of our Class A common stock of an opportunity to receive a premium for their Class A common stock as part of a sale of our company. The concentration of our voting power may adversely affect the ability of new investors to influence our policies. As of December 31, 2020, our Chairman, President and Chief Executive Officer, Anthony E. Malkin, together with the Malkin Group, has the right to vote 40,859,706 shares of our common stock, which represents approximately 18.5% of the voting power of our outstanding common stock. Consequently, Mr. Malkin has the ability to influence the outcome of matters presented to our securityholders, including the election of our board and approval of significant corporate transactions, 24 including business combinations, consolidations and mergers and the determination of our day-to-day corporate and management policies. As of December 31, 2020, QIA had a 10.48% fully diluted interest in us, which represented 17.53% of the outstanding Class A common stock. Pursuant to the terms of our stockholders agreement with QIA, QIA generally has the right (but not the obligation) to maintain its fully diluted economic interest in us by purchasing additional shares of our Class A common stock when we or our operating partnership issue additional common equity securities from time to time. While QIA has agreed to limit its voting power on all matters presented to our 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 our board. The interests of Mr. Malkin and QIA could conflict with or differ from your interests as a holder of our common stock, 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. Tax consequences to holders of operating partnership units upon a sale or refinancing of our properties may cause the interests of certain members of our senior management team to differ from your own. 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, President and Chief Executive Officer, Anthony E. Malkin, and our Chairman Emeritus, Peter L. Malkin, may suffer different and more adverse tax consequences than holders of our Class A common stock upon the sale or refinancing of the properties owned by our operating partnership, 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 and other material terms of any sale or refinancing of certain properties, or whether to sell 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 our senior management team to attempt to delay, defer or prevent a transaction that might otherwise be in the best interests of our other securityholders. Additionally, in connection with the formation transactions, we entered into a tax protection agreement with Messrs. Malkin pursuant to which we have agreed to indemnify the Malkin Group and one additional third party investor in Metro Center against certain tax liabilities if those tax liabilities arise from a transaction involving one of four properties. Refer to “Financial Statements – Note 10 – Related Party Transactions – Excluded Properties and Businesses” for more information. As a result of entering into the tax protection agreement, Messrs. Malkin may have an incentive to cause us to enter into transactions from which they may personally benefit. Conflicts of interest exist or could arise in the future between the interests of our securityholders and OP unit holders. Conflicts of interest exist or could arise in the future as a result of the relationships between us and our affiliates, on the one hand, and our operating partnership or any partner thereof, on the other. Our directors and officers have duties to our company under applicable Maryland law in connection with their management of our company. At the same time, we, as the general partner in our operating partnership, have fiduciary duties and obligations to our operating partnership and its limited partners under Delaware law and the partnership agreement of our operating partnership in connection with the management of our operating partnership. Our fiduciary duties and obligations as general partner to our operating partnership and its partners may come into conflict with the duties of our directors and officers to our company, which may impede business decisions that could benefit our securityholders. Our rights and the rights of our securityholders to take action against our directors and officers are limited, which could limit your recourse in the event of actions not in your best interest. Our charter limits the liability of our present and former directors and officers to us and our securityholders for money damages to the maximum extent permitted under Maryland law. Under current Maryland law, our present and former directors and officers will not have any liability to us or our securityholders for money damages other than liability resulting from (1) actual receipt of an improper benefit or profit in money, property or services or (2) active and deliberate dishonesty by the director or officer that was established by a final judgment and is material to the cause of action. Additionally, the partnership agreement of our operating partnership provides for certain limitations on liability and indemnification obligations for us and our directors and officers and certain present and former members, managers, shareholders, directors, limited partners, general partners, officers or controlling persons of our predecessor. As a result, we and our securityholders may have limited rights against all such persons, which could limit your recourse in the event of actions not in your best interest. Limits on changes in control may discourage takeover attempts beneficial to securityholders. 25 Provisions in our charter and the partnership agreement of our operating partnership, may delay or prevent a change of control over the company or a tender offer, even if such action might be beneficial to the company’s stockholders. Additionally, our board could establish a class or series of preferred stock that could, depending on the terms of such series, delay, defer or prevent a transaction or a change of control. To facilitate maintenance of the company’s qualification as a REIT and to otherwise address concerns relating to concentration of stock ownership, our charter generally prohibits any person from directly or indirectly owning more than 9.8% in value or number of shares, whichever is more restrictive, of the outstanding shares of our capital stock or more than 9.8% in value or number of shares, whichever is more restrictive, of the outstanding shares of our common stock. Our charter also provides that no person can directly or indirectly own shares of our capital stock to the extent such ownership would result in us owning (directly or indirectly) an interest in one of our tenants if the income derived by us from such tenant would reasonably be expected to equal or exceed the lesser of 1% of our gross income or an amount that would cause us to fail to satisfy any of the REIT gross income tests. Shares owned in violation of the ownership limit will be subject to the loss of rights to distributions and voting and other penalties. These ownership limitations could have the effect of discouraging a takeover or other transaction in which holders of our common stock might receive a premium for their shares over the then prevailing market price or which holders might believe to be otherwise in their best interests. Our board may waive, in its sole discretion, or modify the ownership limit with respect to one or more persons if it is satisfied that ownership in excess of this limit will not jeopardize the company’s status as a REIT for U.S. federal income tax purposes. We have entered into such a waiver with QIA, which permits QIA to own up to 15% of the outstanding shares of our Class A common stock and an aggregate amount of Class A common stock equal to a 9.9% fully diluted economic interest in the company (inclusive of all outstanding common OP units and LTIP units), which currently equals approximately 17.53% of our outstanding Class A common stock. Certain provisions in the partnership agreement of our operating partnership may also delay or make more difficult unsolicited acquisitions of us or changes of our control, including, among others: redemption rights of qualifying parties; transfer restrictions on operating partnership units; our ability, as general partner, in some cases, to amend the partnership agreement and to cause the operating partnership to issue units with terms that could delay, defer or prevent a merger or other change of control of us or our operating partnership without the consent of the limited partners; the right of the limited partners to consent to transfers of the general partnership interest and mergers or other transactions involving us under specified circumstances; and a redemption premium payable to the holders of our operating partnership’s preferred units if our operating partnership decides, at its option, to redeem preferred units for cash upon the occurrence of certain fundamental transactions, such as a change of control. Risks Related to our Common Stock and Traded OP Units Our cash available for distribution may not be sufficient to make distributions at expected levels, and the market price of shares of our Class A common stock and traded OP units could be adversely affected by our level of cash distributions. We intend to make distributions to holders of shares of our common stock and holders of operating partnership units. All dividends and distributions will be made at the discretion of our board and will depend on our earnings, financial condition, maintenance of REIT qualification and other factors as our 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 our Class A common stock and traded OP units. The future exercise of registration rights may adversely affect the market price of our common stock. In August 2016, we entered into a registration rights agreement with QIA in connection with its purchase of our Class A common stock, which requires us, subject to certain conditions, to maintain an effective shelf registration statement with the SEC providing for the resale of QIA’s shares. The current registration statement filed on July 31, 2020 registers up to 29,894,869 shares. If QIA decides to sell all or a substantial portion of its shares, or there is market perception that it may intend to do so, it could have a material adverse impact on the market price of our Class A common stock. Future issuances of debt or equity securities or preferred units may be dilutive to current securityholders and may materially adversely affect the market price of our traded securities. 26 In the future, we may issue debt or equity securities or make other borrowings. Our board, without stockholder approval, has the power under our charter to cause the company to issue additional shares of capital stock or debt securities, and our operating partnership may also issue additional operating partnership units without the consent of our securityholders. Upon liquidation, holders of our debt securities, preferred units and other loans and preferred shares will receive a distribution of our available assets before holders of shares of our common stock. We are not required to offer any such additional debt or equity securities to existing securityholders on a preemptive basis. Therefore, additional shares of our common stock issuances, directly or through convertible or exchangeable securities (including operating partnership units), warrants or options, will dilute the holdings of our existing common securityholders and such issuances or the perception of such issuances may reduce the market price of shares of our common stock. Additionally, our preferred units or shares, if issued, would likely have a preference on distribution payments, periodically or upon liquidation, which could limit our ability to make distributions to holders of shares of our common stock. ITEM 1B. UNRESOLVED STAFF COMMENTS As of December 31, 2020, we did not have any unresolved comments from the staff of the SEC. 27 ITEM 2. PROPERTIES Our Portfolio Summary As of December 31, 2020, our portfolio consisted of 14 office properties and six standalone retail properties totaling approximately 10.1 million rentable square feet and was approximately 85.9% occupied, yielding approximately $542.7 million of annualized rent. Giving effect to leases signed but not yet commenced, our portfolio was approximately 88.7% leased as of December 31, 2020. In addition, we owned entitled land that will support the development of an approximately 0.4 million rentable square foot office building and garage ("Metro Tower") at the Stamford Transportation Center in Stamford, Connecticut, adjacent to one of our office properties.

These increased rents are partly due to an increase in the total rentable square footage of such space as a result of remeasurement and application of market loss factors to our space. The following table sets forth new and renewal leases entered into at our Manhattan office properties (excluding the retail component of these properties), the weighted average annualized cash rent per square foot for new and renewal leases executed during the year, the previous weighted average annualized cash rent prior to the renewal or re-leasing of these leases and the percent increase in mark-to market rent.

Represents license fees for the use of the Empire State Building mast and base rent for the physical space occupied by broadcasting tenants. Undeveloped Properties We own entitled land in Stamford, Connecticut, adjacent to one of our office properties, that will support the development of an approximately 0.4 million rentable square foot office building and garage. The site is directly adjacent to Metro Center, one of our office properties, and the Stamford Transportation Center. All required zoning approvals have been obtained to allow for development of Metro Tower. We intend to develop Metro Tower when the appropriate combination of local market and other conditions is in place. Redevelopment and Repositioning From 2002 through 2006, we gradually gained full control of the day-to-day management of our Manhattan office properties (with the estate of Leona M. Helmsley previously holding certain approval rights at some of these properties as a result of its interest in the entities owning the properties). Since then, we have been undertaking a comprehensive redevelopment and repositioning strategy of our Manhattan office properties that has included the physical improvement through upgrades and modernization of, and tenant upgrades in, such properties. Since we assumed full control of the day-to- day management of our Manhattan office properties beginning with One Grand Central Place in 2002, and through December 31, 2020, we have invested a total of approximately $948.1 million (excluding tenant improvement costs and leasing commissions) in our Manhattan office properties pursuant to this program. We intend to fund capital improvements through a combination of operating cash flow, cash on hand and borrowings. The improvements, within our redevelopment and repositioning program, include restored, renovated and upgraded or new lobbies, elevator modernization, renovated public areas and bathrooms, refurbished or new windows, upgrade and standardization of retail storefront and signage, façade restorations, modernization of building-wide systems, with a focus on energy efficiency and indoor environmental quality, and enhanced tenant amenities. These improvements are designed to 34 improve the overall value and attractiveness of our properties and have contributed significantly to our tenant repositioning efforts, which seek to increase our occupancy, raise our rental rates, increase our rentable square feet, increase our aggregate rental revenue, lengthen our average lease term, increase our average lease size, and improve our tenant credit quality. We have also aggregated smaller spaces in order to offer larger blocks of office space, including multiple floors, that are attractive to larger, higher credit-quality tenants, as well as to offer new, pre-built suites with improved layouts. This strategy has shown what we believe to be attractive results to date, and we believe has the potential to improve our operating margins and cash flows in the future. We believe we will continue to enhance our tenant base and improve rents as our pre-redevelopment leases continue to expire and be re-leased. During the second quarter of 2017, we commenced a multi-year capital project at the Empire State Building which we believe improves the convenience for office tenants and their visitors, increases the value of our 34th Street facing retail space, enhances the observatory visitor experience, and increases observatory revenue per capita. In the first phase of the project, which we completed in the third quarter 2018, we relocated the present observatory entrance, previously located on Fifth Avenue, to a new, larger, dedicated entrance for observatory visitors at the western side of the Empire State Building on 34th Street. The new entrance eliminates observatory visitor flow into the Fifth Avenue lobby and streamlines the visitor exit from that lobby, thereby reducing observatory traffic in the lobby by more than 50% and improving Fifth Avenue access for our office tenants and their visitors. During the third quarter 2019 we completed the second phase of the project, the new second floor galleries and in the fourth quarter 2019 we completed the final phase, the redevelopment of the 80th floor and opened the newly renovated 102nd floor observatory. Expenditures, which began during the second quarter 2017, totaled $157.9 million through December 31, 2020. This investment is an example of continually looking at ways to innovate and enhance the office and retail tenant and visitor experience at the Empire State Building. The greater New York metropolitan area office market is soft, and we compete with properties that have been redeveloped recently or have planned redevelopment. We have spent approximately $36 million over 2018 through 2020 on our well-maintained and well-located properties’ common areas and amenities to ensure competitiveness and protect our market position.

MINE SAFETY DISCLOSURE Not applicable. 35 PART II ITEM 5. MARKET FOR REGISTRANT'S COMMON EQUITY, RELATED STOCKHOLDER MATTERS AND ISSUER PURCHASES OF EQUITY SECURITIES Market Information Our Class A common stock is listed on the New York Stock Exchange (the "NYSE"), under the symbol "ESRT." Our Class B common stock is not listed on any exchange and is not traded. Each share of Class B common stock may be converted to one share of Class A common stock at any time. Our operating partnership has four series of partnership units ("OP Units") - Series PR OP Units, Series ES OP Units, Series 60 OP Units and Series 250 OP Units. The Series ES OP Units, Series 60 OP Units and Series 250 OP Units (together, the "traded OP units") are listed on the NYSE Arca, Inc. exchange ("NYSE Arca") under the symbols "ESBA," "OGCP," and "FISK," respectively. The Series PR OP Units are not listed on any exchange and are not traded. On February 19, 2021, the last sales price for our Class A common stock on the NYSE was $9.89 per share. Holders As of February 19, 2021, we had 579 registered holders of our Class A common stock and 602 registered holders of our Class B common stock. As of February 19, 2021, our operating partnership had 632 registered holders of Series PR OP Units, 1,444 registered holders of Series ES OP Units, 440 registered holders of Series 60 OP Units and 309 registered holders of Series 250 OP Units. Certain shares of common stock and OP Units are held in "street" name and accordingly, the number of beneficial owners of such shares of common stock and OP Units is not known or included in the foregoing totals. Dividends We intend to pay regular quarterly dividends to holders of our Class A common stock and Class B common stock, at least to the extent of our taxable income or as required to maintain our qualification as a REIT. Any distributions we pay in the future will depend upon our taxable income, actual results of operations, economic conditions and other factors that could differ materially from our current expectations. Our actual results of operations will be affected by a number of factors, including the revenue we receive from our properties, our operating expenses, interest expense, the ability of our tenants to meet their obligations and unanticipated expenditures. During August 2020, we announced the suspension of our third and fourth quarter 2020 dividends to holders of our Class A common stock and Class B common stock and to holders of Empire State Realty OP, L.P.’s Series ES, Series 250 and Series 60 operating partnership units and Series PR operating partnership units. We had no taxable income in 2020, and therefore no requirement to pay any dividend on our common stock in either the third or fourth quarter of 2020. During December 2020, we announced the continued dividend suspension for the first and second quarters of 2021. We and our board believe that payment of a dividend is currently not the highest and best use of our balance sheet. Our board regularly reviews our dividend policy. Distributions declared by us will be authorized by our board in its sole discretion out of funds legally available therefore and will be dependent upon a number of factors, including restrictions under applicable law, our capital requirements and the distribution requirements necessary to maintain our qualification as a REIT. See Item 1A, "Risk Factors," and Item 7, "Management's Discussion and Analysis of Financial Conditions and Results of Operations," of this Annual Report on Form 10-K, for information regarding the sources of funds used for dividends and for a discussion of factors, if any, which may adversely affect our ability to make distributions to our securityholders. Earnings and profits, which determine the tax treatment of distributions to securityholders, will differ from income reported for financial reporting purposes due to the differences for federal income tax purposes, including, but not limited to, treatment of loss on extinguishment of debt, revenue recognition, compensation expense, and basis of depreciable assets and estimated useful lives used to compute depreciation. Dividends paid in the first quarter and second quarter of 2020 of $0.21 per share are classified for income tax purposes 100% as taxable ordinary dividends eligible for the Section 199A deduction. Stockholder Return Performance The following graph is a comparison of the cumulative total stockholder return on our Class A common stock, the Standard & Poor's 500 Index (the "S&P 500 Index"), the FTSE NAREIT All Equity Index (the "FTSE NAREIT All Equity Index") and the FTSE NAREIT Equity REIT Office Index ("FTSE NAREIT Equity REIT Office Index"). The graph assumes 36 that $100.00 was invested on December 31, 2015 and dividends were reinvested without the payment of any commissions. There can be no assurance that the performance of our Class A common stock will continue in line with the same or similar trends depicted in the graph below. 225 200 175 e u l a V x e d n I 150 125 100 75 50 12/31/15 12/31/16 12/31/17 12/31/18 12/31/19 12/31/20 Period Ending Empire State Realty Trust, Inc.

Securities Authorized For Issuance Under Equity Compensation Plans On May 16, 2019, our shareholders approved the Empire State Realty Trust, Inc. Empire State Realty OP, L.P. 2019 Equity Incentive Plan (the “2019 Plan”). The 2019 Plan provides for grants to directors, employees and consultants of our company and operating partnership, including options, restricted stock, restricted stock units, stock appreciation rights, performance awards, dividend equivalents and other equity-based awards, including LTIP units. An aggregate of approximately 11.0 million shares of our common stock are authorized for issuance under awards granted pursuant to the 2019 Plan. Following adoption by our shareholders of the 2019 Plan, we agreed not to issue any new equity awards under the First Amended and Restated Empire State Realty Trust, Inc. and Empire State Realty OP, L.P. 2013 Equity Incentive Plan ("2013 Plan", and collectively with the 2019 Plan, "the Plans"), which we adopted upon our IPO in 2013. The shares of Class A common stock underlying any awards under the 2019 Plan and the 2013 Plan that are forfeited, canceled or otherwise terminated, other than by exercise, will be added back to the shares of Class A common stock available for issuance under the 37 2019 Plan. For a further discussion of the Plans, see Note 9 to the consolidated financial statements included under Item 8 "Financial Statements and Supplementary Data" of this Annual Report on Form 10-K.

Recent Sales of Unregistered Securities Use of Proceeds from Registered Securities; Not applicable. Repurchases of Equity Securities Stock and Publicly Traded Operating Partnership Unit Repurchase Program On December 13, 2019, our board authorized the repurchase of up to $500 million of our Class A common stock and the Operating Partnership’s Series ES, Series 250 and Series 60 operating partnership units from January 1, 2020 through December 31, 2020 ("the 2020 Repurchase Program"). On December 11, 2020, our board approved a new authorization for the repurchase of up to $500 million of such securities from January 1, 2021 through December 31, 2021. Under the repurchase 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 and general market conditions. 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.

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, 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 from 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. For a reconciliation of FFO, see "Item 7. Management's Discussion and Analysis of Financial Condition and Results of Operations - Funds from Operations." (2) Modified FFO adds back an adjustment for any above or below-market ground lease amortization to traditionally defined FFO. We consider 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 consider it 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 accordance with GAAP or to cash flow from operating activities determined in accordance with GAAP. Modified FFO is not indicative of cash available to fund ongoing cash needs, including the ability to make cash distributions. (3) Core FFO adds back to traditionally defined FFO the following items: acquisition expenses, severance expenses and retirement equity compensation expenses, private perpetual preferred exchange offering expenses, deferred tax asset write-off, acquisition expenses, loss on early extinguishment of debt, gain on settlement of lawsuit related to the Observatory, net of income taxes and ground lease amortization, construction severance expenses and acquisition break-up fee. We present Core FFO because we consider it an important supplemental measure of our operating performance in that it excludes items associated with the Offering and formation transactions. There can be no assurance that Core FFO presented by us 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. For a reconciliation of Core FFO, see "Item 7. Management's Discussion and Analysis of Financial Condition and Results of Operations - Core Funds from Operations." (4) Reflects a $4.1 million write-off of prior expenditures on a potential energy efficiency project that is not economically feasible in today's regulatory environment and a $2.1 million write-off of prior expenditures on a development project that is unlikely to continue. (5) Represents an accrued expense which reflects an estimated liability associated with the Initial Public Offering-related litigation.

Prospective investors should not place undue reliance on any forward- looking statements, which are based only on information currently available to the company. Overview Unless the context otherwise requires or indicates, references in this section to "we," "our" and "us" refer to our company and its consolidated subsidiaries. The following discussion and analysis should be read in conjunction with "Selected Financial Data," and our consolidated financial statements as of December 31, 2020 and 2019 and for the years ended December 31, 2020, 2019 and 2018 and the notes related thereto which are included in this Annual Report on Form 10-K. 42 2020 Highlights • • • • • Net loss attributable to the company was $16.7 million. Core FFO was $175.4 million. Signed 104 leases, new, renewal, and expansion leases, representing 923,379 rentable square feet. There were 28 new leases representing 540,643 rentable square feet for the Manhattan office portfolio. This includes approximately 315,000 rentable square feet from deals with existing tenants within the portfolio. Reduced property operating expenses by $39 million compared to full year 2019, driven by reduced building utilization and the Company's cost reduction initiatives. Reopened the Empire State Building 86th floor observation deck on July 20, 2020 and the 102nd floor observation deck on August 24, 2020, as one of the earliest tourist attractions in New York City following earlier pandemic driven closure. As of December 31, 2020, our total portfolio contained 10.1 million rentable square feet of office and retail space. We owned 14 office properties (including three long-term ground leasehold interests) encompassing approximately 9.4 million rentable square feet of office space. Nine of these properties are located in the midtown Manhattan market and aggregate approximately 7.6 million rentable square feet of office space, including the Empire State Building. Our Manhattan office properties also contain an aggregate of 0.5 million rentable square feet of premier retail space on their ground floor and/or contiguous levels. Our remaining five office properties are located in Fairfield County, Connecticut and Westchester County, New York, encompassing in the aggregate approximately 1.8 million rentable square feet. The majority of square footage for these five properties is located in densely populated metropolitan communities with immediate access to mass transportation. Additionally, we have entitled land at the Stamford Transportation Center in Stamford, Connecticut, adjacent to one of our office properties, that will support the development of an approximately 0.4 million rentable square foot office building and garage, which we refer to herein as Metro Tower. As of December 31, 2020, our portfolio included four standalone retail properties located in Manhattan and two standalone retail properties located in the city center of Westport, Connecticut, encompassing 0.2 million rentable square feet in the aggregate. The Empire State Building is our flagship property. The Empire State Building provides us with a diverse source of revenue through its office and retail leases, observatory operations, and broadcasting licenses and related leased space. Our observatory operations are a separate reporting segment. Our observatory operations are subject to regular patterns of tourist activity in Manhattan. Historically, prior to the outbreak of COVID-19, approximately 16.0% to 18.0% of our annual observatory revenue was realized in the first quarter, 26.0% to 28.0% was realized in the second quarter, 31.0% to 33.0% was realized in the third quarter, and 23.0% to 25.0% was realized in the fourth quarter. The components of the Empire State Building revenue are as follows (dollars in thousands): Office leases Retail leases Tenant reimbursements, lease termination fees and other income Observatory operations Broadcasting licenses and leases Total Year Ended December 31, 2020 2019 $ 140,644 64.7 % $ 143,561 43.8 % 7,132 20,772 29,057 19,767 3.3 % 7,500 9.6 % 31,030 13.4 % 128,769 9.0 % 16,847 2.3 % 9.6 % 39.2 % 5.1 % $ 217,372 100.0 % $ 327,707 100.0 % We have been undertaking a comprehensive redevelopment and repositioning strategy of our Manhattan office properties. This strategy is designed to improve the overall value and attractiveness of our properties and has contributed significantly to our tenant repositioning efforts, which seek to increase our occupancy, raise our rental rates, increase our rentable square feet, increase our aggregate rental revenue, lengthen our average lease term, increase our average lease size, and improve our tenant credit quality. These improvements include restored, renovated and upgraded or new lobbies, elevator modernization, renovated public areas and bathrooms, refurbished or new windows, upgrade and standardization of retail storefront and signage, façade restorations, modernization of building-wide systems, and enhanced tenant amenities. We 43 have also aggregated smaller spaces in order to offer larger blocks of office space, including multiple floors, that are attractive to larger, higher credit-quality tenants as well as to offer new, pre-built suites with improved layouts. This strategy has shown what we believe to be attractive results to date, and we believe has the potential to improve our operating margins and cash flows in the future. We believe we will continue to enhance our tenant base and improve rents as our pre-redevelopment leases continue to expire and be re-leased. From 2002 through December 31, 2020, we have invested a total of approximately $948.1 million (excluding tenant improvement costs and leasing commissions) in our Manhattan office properties pursuant to this program. We intend to fund these capital improvements through a combination of operating cash flow, cash on hand, short term investments and borrowings. During the second quarter 2017, we commenced a multi-year capital project at the Empire State Building, which we completed during the fourth quarter 2019, that we believe improves the convenience for office tenants and their visitors, increases the value of our 34th Street facing retail space, enhances the Observatory visitor experience, and increases Observatory revenue per capita. In the first phase completed in August 2018, we relocated the Observatory entrance, previously located on Fifth Avenue, to a new, larger, dedicated entrance for Observatory visitors at the western side of the Empire State Building on 34th Street. The new entrance eliminates Observatory visitor flow into the Fifth Avenue lobby and streamlines the visitor exit from that lobby, thereby reducing Observatory traffic in the lobby by 50% and improving Fifth Avenue access for our office tenants and their visitors. During the third quarter 2019, we opened the second phase of the project, the new second floor galleries and in the fourth quarter 2019 we completed the final phase, the redevelopment of the 80th floor and opened the newly renovated 102nd floor observatory. We have now completed all phases of this project. Expenditures for the improvement project, which began during the second quarter 2017, were $157.9 million through December 31, 2020. This investment is an example of continually looking at ways to innovate and enhance the office and retail tenant and visitor experience at the Empire State Building. In the Greater New York metropolitan area office market, we compete with properties that have been redeveloped recently or have planned redevelopment. We have spent approximately $36 million over 2018 through 2020 on our well- maintained and well-located properties’ common areas and amenities to ensure competitiveness and protect our market position. As of December 31, 2020, we had total debt outstanding of approximately $2.2 billion, with a weighted average interest rate of 3.91% and a weighted average maturity of 8.2 years and 94.2% of which is fixed-rate indebtedness. Excluding principal amortization, we have no outstanding debt maturing until November 2024. As of December 31, 2020, we had cash and cash equivalents of $526.7 million. Our consolidated net debt to total market capitalization was approximately 37.2% as of December 31, 2020. Impact of COVID-19 In March 2020, the outbreak of the novel Coronavirus Disease 2019 ("COVID-19") was recognized as a pandemic by the World Health Organization. The spread of COVID-19 has created a global public health crisis that has resulted in unprecedented economic, social and political uncertainty, volatility and disruption in the United States and globally. We have taken the following actions in response to the impact of the COVID-19 pandemic on our business. Liquidity During 2020, we bolstered our balance sheet to ensure proper liquidity by raising $480.0 million in net proceeds in three financings. In March 2020, we drew down $550.0 million under our $1.1 billion unsecured revolving facility and in September 2020, we repaid the $550.0 million draw. We currently hold $526.7 million in cash on our balance sheet and have $1.1 billion undrawn capacity under our revolving credit facility. Our revolving credit facility matures in August 2021 and has two six-month extension options, subject to certain conditions. As expected, we have begun a process to evaluate a potential recast or extension of the credit facility. Property Operations All of our office buildings have remained open during the COVID-19 pandemic to tenants that provide essential goods and services, as permitted by the authorities. We have scaled back certain building operations in cleaning, security, lobby concierge and recurring maintenance, which will reduce costs until buildings are repopulated. A portion of the reduction in operating expenses will be offset by a reduction in tenant expense recoveries. 44 Our operations team worked diligently to develop plans for tenants' reoccupation of our buildings to ensure a safe, clean and healthy work environment. These plans involve additional staffing, cleaning and maintenance, and changes to building operations for access by tenants and their guests. All New York State capital improvement work, except for essential work as defined by the authorities which includes safety-related work and work to demobilize previously started projects, was stopped in March 2020 until June 8, 2020, when government restrictions were lifted. Our spend on such capital improvement work in 2020 was significantly curtailed under the restrictions. Despite the challenge of the uncertain near-term environment, we continue to believe in the long-term demand for office space. We believe many tenants have now experienced the inefficiencies of working from home and miss the connectivity and productivity that an office environment provides. That said, we believe the pandemic may cause some fundamental changes to how tenants use their office space in the future including less densification and smarter open floor plans with appropriate spacing. We also believe current co-working build-outs are too dense and will be poorly positioned for tenant demand in the new paradigm. Leasing The economic uncertainty relating to the COVID-19 pandemic has slowed the pace of our leasing activity and could result in higher vacancy than we otherwise would have experienced, a longer amount of time to fill vacancies and potentially lower rental rates. As of December 31, 2020, our portfolio was 88.7% leased, including signed leases not yet commenced, including 6.4% subject to leases scheduled to expire in 2021 and 5.5% subject to leases scheduled to expire in 2022. New leasing activity was impacted during 2020 by the pandemic and shelter-in-place rules that were in effect for much of the period. During this time period, we instituted a number of online measures to maintain our relationships with brokers and expose our availabilities to the market. While physical tours resumed on June 22, 2020 and coincided with Phase 2 reopening, we had lower leasing volumes for the third and fourth quarters of 2020 based on current tenant activity. Our smaller food and service type retailers have been hit particularly hard. They provide critical amenities and services to our office tenants. In many instances, we have converted some of their fixed rent to a percentage rent structure, with a payback of the difference between current and percentage rent over a defined period. We intend to support our food and service retailers so that they can service our office tenants when they re-occupy. Observatory Operations On March 16, 2020, we complied with governmental mandates regarding the closing of non-essential businesses in response to the COVID-19 pandemic and closed the Empire State Building observatory. While closed, we reduced our annualized operating expense run-rate from $35 million in February 2020 to approximately $14 million in May 2020, a 60% reduction. Approximately two-thirds of the reduction was attributable to lower payroll expenses as we furloughed staff and the balance is due to lower operational and other costs. The observatory reopened under New York State's Phase 4 guidelines, Low-Risk Outdoor Arts and Entertainment, on July 20, 2020. The 102nd observation deck was reopened on August 24, 2020. We anticipate that initially we will have a higher local visitor mix, followed by a ramp up of nationally sourced travel, which will then be followed by a restoration of our typical visitor mix that is approximately two-thirds international which we do not expect to be achieved until the broad resumption of international air travel some time in 2022. With the observatory reopened, for the balance of 2020, we operated with reduced hours, staffing, services, operating costs, credit card fees and marketing expenses. The closure of our observatory caused us during each quarter of 2020 to choose to perform an impairment test related to goodwill. We engaged a third-party valuation consulting firm to perform the valuation process. Based upon the results of the goodwill impairment test of the stand-alone observatory reporting unit, which is after the intercompany rent expense paid to the Real Estate reporting unit, we determined that the fair value of the observatory reporting unit exceeded its carrying value by less than 5.0%. Many of the factors employed in determining whether or not goodwill is impaired are outside of our control and it 45 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 and that continued assessment may again utilize a third-party valuation consulting firm. Goodwill allocated to the observatory reporting unit was $227.5 million at December 31, 2020. Expense Reductions We have undertaken meaningful cost reduction measures to ensure our ongoing strength and position the business optimally through the current environment broken down as follows: • Named Executive Officer ("NEO") compensation: ▪ ▪ ▪ ($0.4) million from reduction in annual base salary for Anthony E. Malkin, our Chairman, President and Chief Executive Officer, and Thomas P. Durels, our Executive Vice President, Real Estate, through December 31, 2020; ($1.2) million from the change in age requirement from 60 to 65 for the accounting vesting period for time-based equity compensation; and ($2.7) million from the departure of our former Chief Operating Officer. • • • Other corporate overhead: ▪ ($1.5) million of net changes from the addition of investment personnel and reductions in executive and corporate staff, and temporary corporate salary reductions through December 31, 2020; and Balance from department budget cuts and lower anticipated spending due to the COVID-19 pandemic. In addition, we announced a $3.9 million reduction in 2021 NEO annual equity compensation, comprised of a $2.7 million reduction for Mr. Malkin and $1.2 million reduction for Mr. Durels. Property operating expenses ▪ For the year ended December 31, 2020, we reduced property operating expenses by $39 million compared to the prior year period, driven by reduced tenant utilization and our cost reduction initiatives. $4 million on an annualized basis of permanent cost reductions due to staffing and other reductions. ▪ ▪ • Observatory expenses ▪ 2020 expenses totaled $24 million, reduced from 2019 pre-COVID level of $34 million. Results of Operations Overview The discussion below relates to the financial condition and results of operations for the years ended December 31, 2020, 2019, and 2018. Year Ended December 31, 2020 Compared to the Year Ended December 31, 2019 The following table summarizes the historical results of operations for the years ended December 31, 2020 and 2019 (amounts in thousands): 46 Revenues: Rental revenue Observatory revenue Lease termination fees Third-party management and other fees Other revenues and fees Total revenues Operating expenses: Property operating expenses Ground rent expenses General and administrative expenses Observatory expenses Real estate taxes Impairment charges Depreciation and amortization Total operating expenses Operating income Other income (expense): Interest income Interest expense Loss on early extinguishment of debt IPO litigation expense Income (loss) before income taxes Income tax benefit (expense) Net income (loss) Private perpetual preferred unit distributions Net (income) loss attributable to non-controlling interests Net income (loss) attributable to common shareholders Rental Revenue and Tenant Expense Reimbursement Years Ended December 31, 2020 2019 Change % $ 563,071 29,057 9,416 1,225 6,459 609,228 $ 586,414 128,769 4,352 1,254 10,554 731,343 $ (23,343) (99,712) 5,064 (29) (4,095) (122,115) (4.0) % (77.4) % 116.4 % (2.3) % (38.8) % (16.7) % 136,141 9,326 62,244 23,723 121,923 6,204 191,006 550,567 174,977 9,326 61,063 33,767 115,916 — 181,588 576,637 38,836 — (1,181) 10,044 (6,007) (6,204) (9,418) 26,070 22.2 % — % (1.9) % 29.7 % (5.2) % — % (5.2) % 4.5 % 58,661 154,706 (96,045) (62.1) % 2,637 (89,907) (86) (1,165) (29,860) 6,971 (22,889) (4,197) 10,374 (16,712) $ 11,259 (79,246) — — 86,719 (2,429) 84,290 (1,743) (33,102) 49,445 $ (8,622) (10,661) (86) (1,165) (76.6) % (13.5) % — % — % (116,579) (134.4) % 387.0 % (107,179) (127.2) % (2,454) (140.8) % 131.3 % 43,476 $ (66,157) (133.8) % 9,400 We adopted FASB Topic 842 using the modified retrospective approach as of January 1, 2019 and elected to apply the transition provisions of the standard at adoption. As such, the prior period amounts presented under ASC 840 were not restated to conform with the 2020 and 2019 presentation. We adopted the practical expedient in Topic 842, which allowed us to avoid separating lease and non-lease rental income. Consequently, all rental income earned pursuant to tenant leases in 2020 and 2019 is reflected as one category, “Rental Revenue,” in the 2020 and 2019 consolidated statements of operations. The following table reflects the components of 2020 and 2019 rental revenue: Rental revenue Base rent Tenant expense reimbursement Total rental revenue Year Ended December 31, 2020 Year Ended December 31, 2019 $ $ 498,258 $ 64,813 563,071 $ 511,136 75,278 586,414 The preceding table of the components of rental revenue is not, and is not intended to be, a presentation in accordance with GAAP. It is provided here based on our understanding that such information is frequently used by management, investors, securities analysts and other interested parties to evaluate our performance. The decrease in rental revenue was attributable to the write-off of straight-line receivables and uncollectible tenant receivables and lower tenant expense reimbursements, consistent with lower property operating expenses. 47 Observatory Revenue Observatory revenues were lower driven by the closure of the Observatory on March 16, 2020 due to the COVID-19 pandemic. The Observatory reopened on July 20, 2020 but New York tourism continues to be impacted by international, national, and local travel restrictions and quarantines. Prior to the closure, Observatory revenues increased during the first two months of 2020 by 13.2%, after adjusting for the 102nd floor observation deck, to $14.4 million from $12.7 million in the first two months of 2019. Lease Termination Fees Higher termination fees were earned in the year ended December 31, 2020 compared to the year ended December 31, 2019. Third-Party Management and Other Fees Management fee income was consistent with prior year. Other Revenues and Fees The decrease in other revenues and fees was due to lower food and beverage sales and lower parking income due to the COVID-19 pandemic. Property Operating Expenses The decrease in property operating expenses was primarily due to lower repair and maintenance costs, lower payroll costs, lower utility costs and lower professional fees. Ground Rent Expenses The ground rent expense was consistent with 2019. General and Administrative Expenses The increase in general and administrative expenses was primarily due to severance costs and equity compensation expense, partially offset by lower legal leasing costs. Observatory Expenses Lower Observatory expenses were driven by the closure of the Observatory due to the COVID-19 pandemic, lower payroll costs and lower credit card fees and marketing expenses. Real Estate Taxes The increase in real estate taxes was primarily attributable to higher assessed values for multiple properties. Impairment charges Reflects a $4.1 million write-off of prior expenditures on a potential energy efficiency project that is not economically feasible in today's regulatory environment and a $2.1 million write-off of prior expenditures on a development project that is unlikely to continue. Depreciation and Amortization The increase in depreciation and amortization reflects tenant improvement write-offs due to the early termination of a tenant and depreciation expense on additional assets placed in service in 2020. 48 Interest Income The decrease in interest income was primarily due to lower interest rates in the current year and higher short-term investments in the prior year. Interest Expense Interest expense increased due to new financings entered into in 2020 and a draw on our unsecured revolving credit facility. The draw on our credit facility was fully repaid on September 1, 2020. Loss on Early Extinguishment of Debt Loss on early extinguishment of debt was incurred in connection with the refinancing of the term loan in the first quarter 2020. IPO Litigation Expense Represents an accrued expense which reflects an estimated liability associated with the Initial Public Offering-related litigation. Refer to “Financial Statements-Note 8-Commitments and Contingencies” in this Annual Report on Form 10-K for a description of relevant legal proceedings. Income Taxes The increase in income tax benefit was attributable to a net loss for the Observatory segment. Private Perpetual Preferred Unit Distributions Private perpetual preferred unit distributions increased due to dividends paid on a new series of private perpetual preferred units issued by the operating partnership in December 2019 in connection with the settlement of an exchange offer for outstanding traded OP units. Holders of the new series of private perpetual preferred units are entitled to receive cumulative preferential annual cash distributions of $0.70 per units when, as and if declared by the board of directors of the company. Net Income Attributable to Non-controlling Interests The decrease represents lower non-controlling ownership percentage due to the redemption of operating partnership units into Class A common shares as well as the issuance of private perpetual preferred units in exchange for operating partnership units. Year Ended December 31, 2019 Compared to the Year Ended December 31, 2018 The following table summarizes the historical results of operations for years ended December 31, 2019 and 2018 (amounts in thousands): 49 Years Ended December 31, 2019 2018 Change % Revenues: Rental revenue Tenant expense reimbursement Observatory revenue Lease termination fees Third-party management and other fees Other revenues and fees Total revenues Operating expenses: Property operating expenses Ground rent expenses General and administrative expenses Observatory expenses Real estate taxes Depreciation and amortization Total operating expenses Operating income Other income (expense): Interest income Interest expense Loss on early extinguishment of debt Loss from derivative financial instruments Income before income taxes Income tax expense Net income Private perpetual preferred unit distributions $ 586,414 $ 493,231 $ 93,183 — 128,769 4,352 1,254 10,554 731,343 72,372 131,227 20,847 1,440 12,394 731,511 174,977 167,379 9,326 61,063 33,767 115,916 181,588 576,637 154,706 9,326 52,674 32,767 110,000 168,508 540,654 190,857 11,259 10,661 (79,246) (79,623) — — — — (72,372) (2,458) (16,495) (186) (1,840) (168) (7,598) — (8,389) (1,000) (5,916) (13,080) (35,983) (36,151) 598 377 — — 86,719 121,895 (35,176) (2,429) (4,642) 2,213 84,290 117,253 (32,963) (1,743) (936) (807) Net income attributable to non-controlling interests (33,102) (50,714) 17,612 Net income attributable to common shareholders $ 49,445 $ 65,603 $ (16,158) 18.9 % (100.0) % (1.9) % (79.1) % (12.9) % (14.8) % — % (4.5) % — % (15.9) % (3.1) % (5.4) % (7.8) % (6.7) % (18.9) % 5.6 % 0.5 % — % — % (28.9) % 47.7 % (28.1) % 86.2 % 34.7 % (24.6) % Rental Revenue and Tenant Expense Reimbursement We adopted FASB Topic 842 using the modified retrospective approach as of January 1, 2019 and elected to apply the transition provisions of the standard at adoption. As such, the prior period amounts presented under ASC 840 were not restated to conform with the 2019 presentation. We adopted the practical expedient in Topic 842, which allowed us to avoid separating lease and non-lease rental income. Consequently, all rental income earned pursuant to tenant leases in 2019 is reflected as one category, “Rental Revenue,” in the 2019 consolidated statement of income. The following table reflects the components of 2019 rental revenue: Rental revenue Base rent Tenant expense reimbursement Total rental revenue Year Ended December 31, 2019 $ $ 511,136 75,278 586,414 We believe the preceding table of the components of rental revenue is not, and is not intended to be, a presentation in accordance with GAAP. It is provided here based on our understanding that such information is frequently used by management, investors, securities analysts and other interested parties to evaluate our performance. 50 The increase in base rent revenue was attributable to increased rental rates, partially offset by decreased broadcasting licenses and holdover rent. The increase in billed tenant expense reimbursement was primarily due to reimbursements related to higher property operating expenses. Observatory Revenue Observatory revenues were lower primarily driven by the closure of the 102nd floor observation deck for approximately nine months in 2019 as part of the Observatory upgrade program and visitor decline, partially offset by improved pricing. Lease Termination Fees The year ended December 31, 2018 included significantly higher lease termination fees, from a combination of broadcast and office tenants, compared to the year ended December 31, 2019. Third-Party Management and Other Fees The decrease reflects lower management fee income due to fewer assets under management. Other Revenues and Fees The decrease in other revenues and fees is primarily due to a $2.8 million settlement with a former broadcast tenant recognized in the year ended December 31, 2018 partially offset by a property tax refund received in the year ended December 31, 2019. Property Operating Expenses The increase in property operating expenses was primarily due to higher repair and labor costs partially offset by lower utility costs. Ground Rent Expenses The ground rent expense was consistent with 2018. General and Administrative Expenses The increase in general and administrative expenses was primarily due to increased equity compensation expenses as well as higher leasing costs which were previously capitalized prior to our adoption of Topic 842, Lease Accounting on January 1, 2019, which requires that non-contingent leasing costs be expensed as incurred. Also contributing to the increase were costs associated with the 2019 private perpetual preferred units exchange offer. Observatory Expenses Observatory expenses increased primarily due to higher information technology consulting fees and higher marketing costs. Real Estate Taxes The increase in real estate taxes was primarily attributable to higher assessed values for multiple properties. Depreciation and Amortization The increase in depreciation and amortization was attributable to additional depreciation on assets newly placed in service during the year as well as the acceleration of depreciation of $2.0 million in connection with a partial termination agreement. 51 Interest Income The increase in interest income was primarily due to higher rates and the timing of short-term time deposits during the year ended December 31, 2019. Interest Expense Interest expense was consistent with 2018. Income Taxes The decrease in income tax expense was attributable to lower revenues and higher operating expenses for the Observatory segment. Private Perpetual Preferred Unit Distributions Private perpetual preferred unit distributions increased due to dividends paid on a new series of private perpetual preferred units issued by the operating partnership in December 2019 in connection with the settlement of an exchange offer for outstanding traded OP units. Holders of the new series of private perpetual preferred units are entitled to receive cumulative preferential annual cash distributions of $0.70 per units when, as and if declared by the board of the company. Net Income Attributable to Non-controlling Interests The decrease represents lower non-controlling ownership percentage due to the redemption of operating partnership units into Class A common shares as well as the issuance of private perpetual preferred units in exchange for operating partnership units. 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 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 to qualify as a REIT, we are required under the Code to distribute to our securityholders, on an annual basis, at least 90% of our REIT taxable income, determined without regard to the deduction for dividends paid and excluding net capital gains. We expect to make quarterly distributions 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, short term investments, cash generated from our operating activities, debt issuances and unused borrowing capacity under our unsecured revolving credit and term loan 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 and term loan 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 and term loan 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 improvements 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. Our charter does not restrict the amount of leverage that we may use. At December 31, 2020, we had approximately $526.7 million available in cash and cash equivalents and there was $1.1 billion available under our unsecured revolving credit facility. 52 Through August 2021, QIA will have a right of first offer to co-invest with us as a joint venture partner in real estate investment opportunities initiated by us where we have elected, at our discretion, to seek out a joint venture partner in real estate investment opportunities. The right of first offer period will be extended for 30 months so long as at least one joint venture transaction is consummated by us and QIA during the initial term, and will be extended for a further 30-month term if at least one more joint venture transaction is consummated during such initial extension period. As of December 31, 2020, we had approximately $2.2 billion of total consolidated indebtedness outstanding, with a weighted average interest rate of 3.91% and a weighted average maturity of 8.2 years. As of December 31, 2020, excluding principal amortization, we had no outstanding debt maturing until November 2024. Our consolidated net debt to total market capitalization was 37.2% as of December 31, 2020. Unsecured Revolving Credit and Term Loan Facilities During March 2020, through the Operating Partnership, we entered into an amendment to an existing credit agreement with the lenders party thereto, Bank of America, N.A., as administrative agent, and Bank of America, Wells Fargo Bank, National Association and Capital One, National Association, as the letter of credit issuers party thereto. The amendment amends the amended and restated senior unsecured revolving credit and term loan facility, entered into in August 2017, with Bank of America, N.A., as administrative agent, Merrill Lynch, Pierce, Fenner & Smith Incorporated and Wells Fargo Securities, LLC as Joint Lead Arrangers and Joint Bookrunners, Wells Fargo, National Association and Capital One, National Association, as co-syndication agents, and the lenders party thereto. This new amended unsecured revolving credit and term loan facility is comprised of a $1.1 billion revolving credit facility and a $215 million term loan facility. We borrowed the term loan facility in full at closing. We also borrowed $550.0 million on the revolving credit facility in March 2020 which we repaid in September 2020. The amended unsecured revolving credit and term loan facility contains an accordion feature that would allow us to increase the maximum aggregate principal amount to $1.75 billion under specified circumstances. Certain of our Operating Partnership's subsidiaries are guarantors of our obligations under the amended unsecured revolving credit and term loan facility. Amounts outstanding under the term loan facility bear interest at a floating rate equal to, at our election, (x) the Eurodollar rate, plus a spread that will range from 1.20% to 1.75% depending upon our leverage ratio, or (y) a base rate, plus a spread that will range from 0.20% to 0.75% depending upon our leverage ratio. If we achieve investment-grade ratings, subject to the terms of the amended unsecured revolving credit and term loan facility, we may elect for amounts outstanding to bear interest at a floating rate equal to, at our election, (x) the Eurodollar rate, plus a spread that will range from 0.85% to 1.65% depending upon our credit rating, or (y) a base rate, plus a spread that will range from 0.0% to 0.65% depending upon our credit rating. Amounts under the revolving credit facility bear interest at a floating rate equal to, at our election, (x) the Eurodollar rate, plus a spread that will range from 1.10% to 1.50% depending upon our leverage ratio or (y) a base rate, plus a spread that will range from 0.10% to 0.50% depending upon our leverage ratio. If we achieve investment-grade ratings, subject to the terms of the amended unsecured revolving credit and term loan facility, we may elect for the amounts outstanding to bear interest at a floating rate equal to, at our election, (x) the Eurodollar rate, plus a spread that will range from 0.825% to 1.55% depending upon our credit rating, or (y) a base rate, plus a spread that will range from 0.0% to 0.55% depending upon our credit rating. We paid certain customary fees and expense reimbursements in connection with the amended unsecured revolving credit and term loan facility, including a facility fee on commitments under the revolving credit facility that range from 0.125% to 0.35%, subject to the terms of the amended unsecured revolving credit and term loan facility. The initial maturity of the unsecured revolving credit facility is August 2021. We have the option to extend the initial term for up to two additional six-month periods, subject to certain conditions, including the payment of an extension fee equal to 0.0625% and 0.075% of the then outstanding commitments under the unsecured revolving credit facility on the first and the second extensions, respectively. As expected, we have begun a process to evaluate a potential recast or extension of the credit facility. The term loan facility matures on March 2025. We may prepay the loans under the amended unsecured revolving credit and term loan facility at any time in whole or in part, subject to reimbursement of the lenders’ breakage and redeployment costs in the case of prepayment of Eurodollar Rate borrowings. Also during March 2020, through the Operating Partnership, we entered into a senior unsecured term loan facility (the “Term Loan Facility”) with Wells Fargo Bank, National Association, as administrative agent, Wells Fargo Securities, LLC as sole bookrunner, Wells Fargo Securities, LLC, Capital One, National Association, U.S. Bank National Association and SunTrust Robinson Humphrey, Inc. as Joint Lead Arrangers, Capital One, National Association, as syndication agent, U.S. Bank National Association and Truist Bank, as documentation agents, and the lenders party thereto. 53 The Term Loan Facility is in the original principal amount of $175 million which we borrowed in full at closing. We may request the 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. Certain of the Operating Partnership's subsidiaries are guarantors of our obligations under the Term Loan Facility. Amounts outstanding under the Term Loan Facility bear interest at a floating rate equal to, at our election, (x) the LIBOR rate, plus a spread that will range from 1.5% to 2.2% depending upon our leverage ratio, or (y) a base rate, plus a spread that will range from 0.5% to 1.2% depending upon our leverage ratio. If we achieve investment-grade ratings, subject to the terms of the Term Loan Facility, we may elect for amounts outstanding to bear interest at a floating rate equal to, at our election, (x) the LIBOR rate, plus a spread that will range from 1.4% to 2.25% depending upon our credit rating, or (y) a base rate, plus a spread that will range from 0.4% to 1.25% depending upon our credit rating. The Term Loan Facility matures on December 31, 2026. We may prepay loans under the Term Loan Facility at any time, in whole or in part, subject to reimbursement of the lenders’ breakage and redeployment costs in the case of prepayment of Eurodollar rate borrowings and, if the prepayment occurs on or before December 31, 2021, a prepayment fee. If the prepayment occurs on or prior to December 31, 2020, the prepayment fee is equal to 2.0% of the principal amount prepaid, and if the prepayment occurs after December 31, 2020 but on or prior to December 31, 2021, the prepayment fee is equal to 1.0% of the principal amount prepaid. Both the amended revolving credit and term loan facility and the Term Loan Facility (collectively, the "Credit Facilities") include the following financial covenants, subject to customary qualifications and cushions: (i) maximum leverage ratio of total indebtedness to total asset value of the loan parties and their consolidated subsidiaries will not exceed 60%, (ii) consolidated secured indebtedness will not exceed 40% of total asset value, (iii) adjusted EBITDA (as defined in the agreement) to consolidated fixed charges will not be less than 1.50x, (iv) the aggregate net operating income with respect to all unencumbered eligible properties to the portion of interest expense attributable to unsecured indebtedness will not be less than 1.75x, and (v) the ratio of total unsecured indebtedness to unencumbered asset value will not exceed 60%. The Credit Facilities contain customary covenants, including limitations on liens, investment, distributions, debt, fundamental changes, and transactions with affiliates, and requires certain customary financial reports. The Credit Facilities also contain customary events of default (subject in certain cases to specified cure periods), including but not limited to non- payment, breach of covenants, representations or warranties, cross defaults, bankruptcy or other insolvency events, judgments, ERISA events, invalidity of loan documents, loss of real estate investment trust qualification, and occurrence of a change of control (as defined in the respective Credit Facilities). As of December 31, 2020, we were in compliance with the covenants, as described below: Financial Covenant Maximum total leverage Maximum secured debt Minimum fixed charge coverage Minimum unencumbered interest coverage Maximum unsecured leverage Mortgage Debt Required December 31, 2020 In Compliance < 60% < 40% > 1.50x > 1.75x < 60% 35.3 % 12.8 % 2.8x 5.8x 26.8 % Yes Yes Yes Yes Yes During November 2020, we closed on a $180.0 million mortgage loan for 250 West 57th Street. This new interest- only loan bears a fixed rate of 2.83% and matures in December 2030. As of December 31, 2020, total mortgage notes payable, net, amounted to $775.9 million. The first maturity is in 2024. Exchangeable Senior Notes During August 2019, we settled the $250.0 million principal amount of the 2.625% Exchangeable Senior Notes in cash. See Note 4 to our consolidated financial statements. 54 Senior Unsecured Notes Series A, B, C, D, E, F, G and H Senior Notes (collectively, "Senior Unsecured Notes") are senior unsecured obligations with an aggregate principal amount of $975.0 million maturing on various dates from 2025 to 2035. These Senior Unsecured Notes are unconditionally guaranteed by each of our subsidiaries that guarantees indebtedness under the unsecured revolving credit and term loan facility. Interest on the Senior Unsecured Notes is payable quarterly. The terms of the Senior Unsecured Notes include customary covenants, including limitations on liens, investment, debt, fundamental changes, and transactions with affiliates and require certain customary financial reports. These terms also require compliance with financial ratios including a maximum leverage ratio, a maximum secured leverage ratio, a minimum fixed charge coverage ratio, a minimum unencumbered interest coverage ratio, and a maximum unsecured leverage ratio. The agreement also contains customary events of default (subject in certain cases to specified cure periods), including but not limited to non-payment, breach of covenants, representations or warranties, cross defaults, bankruptcy or other insolvency events, judgments, ERISA events, the occurrence of certain change of control transactions and loss of real estate investment trust qualification. As of December 31, 2020, we were in compliance with the covenants under the outstanding Senior Unsecured Notes. Leverage Policies We expect to employ leverage in our capital structure in amounts determined from time to time by our board. Although our board has not adopted a policy that limits the total amount of indebtedness that we may incur, we anticipate that our board 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. Our 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, however, we initially intend to maintain a level of indebtedness consistent with our plan to seek an investment grade credit rating. Our board 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 our common stock, growth and acquisition opportunities and other factors.

As of December 31, 2020, we expect to incur additional costs relating to obligations under signed new leases of approximately $121.9 million for tenant improvements and leasing commissions. We intend to fund the tenant improvements and leasing commission costs through a combination of operating cash flow, cash on hand, short term investments and borrowings under the unsecured revolving credit and term loan facilities. Capital expenditures are considered part of both our short-term and long-term liquidity requirements. We intend to fund the capital improvements to complete the redevelopment and repositioning program through a combination of operating cash flow, cash on hand, short term investments and borrowings under the unsecured revolving credit and term loan facilities.

(2) Does not include various standing or renewal service contracts with vendors related to our property management. 56 Off-Balance Sheet Arrangements As of December 31, 2020, we did not have any off-balance sheet arrangements. Distribution Policy In order to qualify as a REIT, we must distribute to our securityholders, on an annual basis, at least 90% of our REIT taxable income, determined without regard to the deduction for dividends paid and excluding net capital gains. In addition, we will be subject to U.S. federal income tax at regular corporate rates to the extent that we distribute less than 100% of our net taxable income (including net capital gains) and will be subject to a 4% nondeductible excise tax on the amount, if any, by which our distributions in any calendar year are less than a minimum amount specified under U.S. federal income tax laws. We intend to distribute our net taxable income to our securityholders in a manner intended to satisfy the REIT 90% distribution requirement and to avoid U.S. federal income tax liability on our income and the 4% nondeductible excise tax. 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 the REIT 90% distribution requirement and to avoid U.S. federal income tax and the 4% nondeductible excise tax in that year. We and our board continue to prioritize balance sheet flexibility and the maximization of our operating runway amidst an uncertain environment. During August 2020, we announced the suspension of our third and fourth quarter 2020 dividends to holders of our Class A common stock and Class B common stock and to holders of Empire State Realty OP, L.P.’s Series ES, Series 250 and Series 60 operating partnership units and Series PR operating partnership units. During December 2020, we announced the continued dividend suspension for the first and second quarters of 2021. Distribution to Equity Holders Distributions and dividends have been made to equity holders in 2018, 2019 and 2020 as follows (amounts in thousands): Year ended December 31, 2018 Year ended December 31, 2019 Year ended December 31, 2020 126,539 127,761 65,047 Stock and Publicly Traded Operating Partnership Unit Repurchase Program Our board reauthorized the repurchase of up to $500 million of our Class A common stock and the Operating Partnership’s Series ES, Series 250 and Series 60 operating partnership units through December 31, 2021. 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 and general market conditions. 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. The following table summarizes our purchases of equity securities for the year ended December 31, 2020: Period Year ended December 31, 2020 Total Number of Shares Purchased 17,279,252 $ Average Price Paid per Share 8.32 57 Total Number of Shares Purchased as Part of Publicly Announced Plan 17,279,252 $ Maximum Approximate Dollar Value Available for Future Purchase (in thousands) 356,287 Cash Flows Comparison of Year Ended December 31, 2020 to the Year Ended December 31, 2019 Net cash. Cash and cash equivalents and restricted cash were $567.9 million and $271.6 million as of December 31, 2020 and 2019, respectively. The increase was primarily due to the issuance of financings, partially offset by the repurchase of common stock during the year ended December 31, 2020. Operating activities. Net cash provided by operating activities decreased by $50.3 million to $182.3 million for the year ended December 31, 2020 compared to $232.6 million for the year ended December 31, 2019 primarily due to lower observatory revenues and the settlement of a derivative contract, offset by lower operating expenses. Investing activities. Net cash from investing activities decreased by $292.8 million to $143.1 million used in investing activities for the year ended December 31, 2020 compared to $149.7 million net cash provided by investing activities for the year ended December 31, 2019 due to proceeds from maturing short-term time deposits in the year ended December 31, 2019 and lower spending on building and improvements due to COVID-19. Financing activities. Net cash from financing activities increased by $638.7 million to $257.2 million provided by financing activities for the year ended December 31, 2020 compared to $381.5 million used in financing activities for the year ended December 31, 2019, primarily due to the net proceeds from issuance of debt in the year ended December 31, 2020 compared to the payment of debt in the year ended December 31, 2019. Comparison of Year Ended December 31, 2019 to the Year Ended December 31, 2018 Net cash. Cash and cash equivalents and restricted cash were $271.6 million and $270.8 million as of December 31, 2019 and 2018, respectively. During the year ended December 31, 2019, the maturity of investments in short-term time deposits was largely offset by capital improvements and expenditures and the repayment of our exchangeable unsecured senior notes resulting in approximately the same balances for cash and cash equivalents and restricted cash at the end of 2019 when compared to 2018. Operating activities. Net cash provided by operating activities decreased by $46.5 million to $232.6 million for the year ended December 31, 2019 compared to $279.0 million for the year ended December 31, 2018 primarily attributable to the return of security deposits to various tenants and to the settlement of a derivative contract. Investing activities. Net cash provided by investing activities increased by $792.7 million to $149.7 million provided by investing activities for the year ended December 31, 2019 compared to $643.0 million net cash used in investing activities for the year ended December 31, 2018 due to proceeds from maturing short-term time deposits, partially offset by increased expenditures for additions to building and improvements in the year ended December 31, 2019. Financing activities. Net cash provided by financing activities decreased by $486.1 million to $381.5 million used in financing activities for the year ended December 31, 2019 compared to $104.6 million provided by financing activities for the year ended December 31, 2018 due to the repayment of our exchangeable unsecured senior notes in 2019. Additionally, the net proceeds from issuance of debt was higher in 2018 compared to 2019. Net Operating Income Our financial reports include a discussion of property net operating income, or NOI. 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 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 and 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 58 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 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): Years Ended December 31, 2019 2020 2018 Net income (loss) Add: General and administrative expenses Depreciation and amortization Interest expense Loss on early extinguishment of debt Income tax expense (benefit) Impairment charges IPO litigation expense Less: Interest income Third-party management and other fees Net operating income Other Net Operating Income Data $ (22,889) $ 84,290 $ 117,253 62,244 191,006 89,907 86 (6,971) 5,360 1,165 61,063 181,588 79,246 — 2,429 — — 52,674 168,508 79,623 — 4,642 — — (2,637) (1,225) (11,259) (1,254) (10,661) (1,440) $ 316,046 $ 396,103 $ 410,599 Straight line rental revenue Net increase in rental revenue from the amortization of above and below- market lease assets and liabilities Amortization of acquired below-market ground leases $ $ $ 5,238 $ 20,057 $ 22,107 3,627 7,831 $ $ 7,311 7,831 $ $ 6,120 7,831 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 writedowns 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 59 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, 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 consider 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 consider it 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 accordance with GAAP or to cash flow from operating activities determined in accordance with GAAP. Modified FFO is not indicative of cash available to fund ongoing cash needs, including the ability to make cash distributions. Core Funds From Operations ("Core FFO") Core FFO adds back to Modified FFO the following items: IPO litigation expense, severance expenses and loss on early extinguishment of debt. The company presents Core FFO because it considers it an important supplemental measure of its operating performance in that it excludes items associated with its IPO and formation transactions and other 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.

Rental Revenue We derive revenues primarily from rents, rent escalations, expense reimbursements and other income received from tenants under existing leases at each of our properties. “Escalations and expense reimbursements” consist of payments made by tenants to us under contractual lease obligations to reimburse a portion of the property operating expenses and real estate taxes incurred at each property. We believe that the average rental rates for in-place leases at our properties are generally below the current market rates, although individual leases at particular properties presently may be leased above, at or below the current market rates within its particular submarket. The amount of net rental income and reimbursements that we receive depends principally on our ability to lease currently available space, re-lease space to new tenants upon the scheduled or unscheduled termination of leases or renew expiring leases and to maintain or increase our rental rates. Factors that could affect our rental incomes include, but are not limited to: local, regional or national economic conditions; an oversupply of, or a reduction in demand for, office or retail space; changes in market rental rates; our ability to provide adequate services and maintenance at our properties; and fluctuations in interest rates, all of which could adversely affect our rental income in future periods. Future economic or regional downturns affecting our submarkets, or downturns in our tenants’ industries, could impair our ability to lease vacant space and renew or re- lease space as well as the ability of our tenants to fulfill their lease commitments, and could adversely affect our ability to maintain or increase the occupancy at our properties. Tenant Credit Risk The economic condition of our tenants may also deteriorate, which could negatively impact their ability to fulfill their lease commitments and in turn adversely affect our ability to maintain or increase the occupancy level and/or rental rates of our properties. Potential tenants may look to consolidate, reduce overhead and preserve operating capital and may also defer strategic decisions, including entering into new, long-term leases at properties. 61 Leasing We signed 0.9 million, 1.3 million, and 1.0 million rentable square feet of new leases, expansions and lease renewals, for the years ended December 31, 2020, 2019, and 2018, respectively. 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 December 31, 2020, there were approximately 1.1 million rentable square feet of space in our portfolio available to lease (excluding leases signed but not yet commenced) representing 11.3% of the net rentable square footage of the properties in our portfolio. In addition, leases representing 6.4% and 5.5% of net rentable square footage of the properties in our portfolio will expire in 2021 and in 2022, respectively. These leases are expected to represent approximately 6.8% and 6.5%, 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 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. Despite the challenge of the uncertain near-term environment, we continue to believe that as we complete the redevelopment and repositioning of our properties we will, over the long-term, experience increased occupancy levels and rents. Over the short term, as we renovate and reposition our properties, including aggregating smaller spaces to offer large blocks of space, we may experience lower occupancy levels as a result of having to relocate tenants to alternative space and the strategic expiration of existing leases. We believe that despite the short-term lower occupancy levels we may experience, we will continue to experience increased rental revenues as a result of the increased rents which we expect to obtain following the redevelopment and repositioning of our properties. Market Conditions The properties in our portfolio are located in Manhattan and the greater New York metropolitan area, which includes Fairfield County, Connecticut and Westchester County, New York. Positive or negative changes in conditions in these markets, such as business hirings or layoffs or downsizing, industry growth or slowdowns, relocations of businesses, increases or decreases in real estate and other taxes, costs of complying with governmental regulations or changed regulation, can impact our overall performance. Observatory and Broadcasting Operations On March 16, 2020, we complied with governmental mandates regarding the closing of non-essential businesses in response to the COVID-19 pandemic and closed the Empire State Building Observatory. The Observatory was closed for the entirety of the second quarter 2020 and reopened the 86th floor observation deck on July 20, 2020 with new protocols and processes under New York State's Phase 4's Low-Risk Outdoor Arts and Entertainment guidelines. The 102nd floor observation deck reopened on August 24, 2020. Observatory revenue for the first two months of 2020 increased by 13.2%, after adjusting for the 102nd floor observation deck, which was closed for redevelopment in first quarter 2019 and re-opened in the fourth quarter 2019. For the year ended December 31, 2020, the Observatory hosted 507,000 visitors, compared to 3,505,000 visitors for the same period in 2019, a decrease of 85.6%. Against the backdrop of international, national and local travel restrictions, quarantines and a nationwide pandemic surge, the Observatory has seen steady, weekly increases in visitors. Our return of attendance to pre-COVID-19 levels is closely tied to national and international travel trends and these remain adversely impacted by developments around the COVID-19 pandemic. Observatory revenue for the year ended December 31, 2020 was $29.1 million, a 77.4% decrease from $128.8 million for the year ended December 31, 2019. The Observatory revenue decline was driven by low visitation levels and less days of operation during the year due to COVID-19. 62 Observatory revenue and admissions are dependent upon the following: (i) the number of tourists (domestic and international) that 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. We license the use of the Empire State Building mast to third party television and radio broadcasters and providers of data communications. We also lease space in the upper floors of the building to such licensees to house their transmission equipment and related facilities. During the year ended December 31, 2020, we derived $13.5 million of revenue and $6.3 million of expense reimbursements from the Empire State Building’s broadcasting licenses and related leases. Operating Expenses Our operating expenses generally consist of depreciation and amortization, real estate taxes, ground lease expenses, repairs and maintenance, security, utilities, property-related payroll, and insurance. Factors that may affect our ability to control these operating costs include: increases in insurance premiums, tax rates, the cost of periodic repair, redevelopment costs and the cost of re-leasing space, the cost of compliance with governmental regulation, including zoning and tax laws, the potential for liability under applicable laws and interest rate levels. If our operating costs increase as a result of any of the foregoing factors, our future cash flow and results of operations may be adversely affected. The expenses of owning and operating a property are not necessarily reduced when circumstances, such as market factors and competition, cause a reduction in income from the property. If revenues drop, we may not be able to reduce our expenses accordingly. Costs associated with real estate investments, such as real estate taxes and maintenance generally, will not be materially reduced even if a property is not fully occupied or other circumstances cause our revenues to decrease. As a result, if revenues decrease in the future, static operating costs may adversely affect our future cash flow and results of operations. If similar economic conditions exist in the future, we may experience future losses. Cost of Funds and Interest Rates As of December 31, 2020, our variable rate debt was $125.0 million which represented 5.8% of our total indebtedness and 2.6% of our total enterprise value. Our variable rate debt may increase to the extent we use available borrowing capacity from our unsecured credit facility to fund capital improvements. Competition The leasing of real estate is highly competitive in Manhattan and the greater New York metropolitan market in which we operate. We compete with numerous acquirers, developers, owners and operators of commercial real estate, many of which own or may seek to acquire or develop properties similar to ours in the same markets in which our properties are located. The principal means of competition are rent charged, location, services provided and the nature and condition of the facility to be leased. In addition, we face competition from other real estate companies including other REITs, private real estate funds, domestic and foreign financial institutions, life insurance companies, pension trusts, partnerships, individual investors and others that may have greater financial resources or access to capital than we do or that are willing to acquire properties in transactions which are more highly leveraged or are less attractive from a financial viewpoint than we are willing to pursue. In addition, competition from new and existing observatories and/or broadcasting operations could have a negative impact on revenues from our observatory and/or broadcasting operations. Adverse impacts on domestic travel and changes in foreign currency exchange rates may also decrease demand in the future, which could have a material adverse effect on our results of operations. If our competitors offer space at rental rates below current market rates, below the rental rates we currently charge our tenants, in better locations within our markets or in higher quality facilities, we may lose potential tenants and may be pressured to reduce our rental rates below those we currently charge in order to retain tenants when our tenants’ leases expire. Critical Accounting Estimates Basis of Presentation and Principles of Consolidation The accompanying consolidated financial statements have been prepared in conformity with GAAP and with the rules and regulations of the SEC represent our assets and liabilities and operating results. The consolidated financial statements include our accounts and our wholly owned subsidiaries as well as our operating partnership and its subsidiaries. All significant intercompany balances and transactions have been eliminated in consolidation. 63 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 as well as whether the entity is a variable interest entity (“VIE”) and we are 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. 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 consolidated balance sheets and in the consolidated statements of income by requiring earnings and other comprehensive income to be attributed to controlling and non-controlling interests. Goodwill Goodwill is tested annually for impairment and is tested for impairment more frequently if events and circumstances indicate that the asset might be impaired. An impairment loss is recognized to the extent that the carrying amount, including goodwill, exceeds the reporting unit’s fair value and the implied fair value of goodwill is less than the carrying amount of that goodwill. Non-amortizing intangible assets, such as trade names and trademarks, are subject to an annual impairment test based on fair value and amortizing intangible assets are tested whenever events or changes in circumstances indicate that the carrying amount may not be recoverable. In compliance with the requirements of authorities, we closed the Empire State Building Observatory on March 16, 2020 due to the COVID-19 pandemic and it remained closed until the 86th floor observation deck was reopened on July 20, 2020. The 102nd observation deck was reopened on August 24, 2020. The closure of our Observatory and subsequent reopening under international, national, and local travel restrictions and quarantines caused us during the quarter to choose to perform an impairment test related to goodwill. We engaged a third-party valuation consulting firm to perform the valuation process. The 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 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. Based upon the results of the goodwill impairment test of the stand-alone Observatory reporting unit, which is after the intercompany rent expense paid to the Real Estate reporting unit, we determined that the fair value of the Observatory reporting unit exceeded its carrying value by less than 5.0%. 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 and that continued assessment may again utilize a third-party valuation consulting firm. Income Taxes We elected to be taxed as a REIT under sections 856 through 860 of the Internal Revenue Code of 1986, as amended, commencing with the taxable year ended December 31, 2013 and believe we qualify as a REIT at December 31, 2020. REITs are subject to a number of organizational and operational requirements, including a requirement that 90% of ordinary “REIT taxable income” (as determined without regard to the dividends paid deduction or net capital gains) be distributed. As a REIT, we will generally not be subject to U.S. federal income tax to the extent that we meet the organizational and operational requirements and our distributions equal or exceed REIT taxable income. For all periods subsequent to the effective date of our REIT election, we have met the organizational and operational requirements and distributions have exceeded net taxable income. Accordingly, no provision has been made for federal and state income taxes. 64 We have elected to treat ESRT Observatory TRS, L.L.C., our subsidiary which holds our observatory operations, and ESRT Holdings TRS, L.L.C., our subsidiary that holds our third party management, construction (through cessation of our construction business in the first quarter of 2015), restaurant, cafeterias, health clubs and certain cleaning operations, as taxable REIT subsidiaries. Taxable REIT subsidiaries may participate in non-real estate activities and/or perform non-customary services for tenants and their operations are generally subject to regular corporate income taxes. Our taxable REIT subsidiaries account for their income taxes in accordance with GAAP, which includes an estimate of the amount of taxes payable or refundable for the current year and deferred tax liabilities and assets for the future tax consequences of events that have been recognized in our financial statements or tax returns. The calculation of the taxable REIT subsidiaries' tax provisions may require interpreting tax laws and regulations and could result in the use of judgments or estimates which could cause its recorded tax liability to differ from the actual amount due. Deferred income taxes reflect the net tax effects of temporary differences between the carrying amounts of assets and liabilities for financial reporting purposes and the amounts used for income tax purposes. The taxable REIT subsidiaries periodically assess the realizability of deferred tax assets and the adequacy of deferred tax liabilities, including the results of local, state, or federal tax audits or estimates and judgments used. As of December 31, 2020, Empire State Realty Trust, Inc. had $67.9 million of net operating loss ("NOL") carryforwards that may be used in the future to reduce the amount otherwise required to be distributed by us to meet REIT requirements. However, for federal income tax purposes, the NOL will not be able to offset more than 80% of our REIT taxable income and, therefore, may not be able to reduce the amount required to be distributed by us to meet REIT requirements to zero, except for the tax year ended December 31, 2020, of which we were able to offset 100% of our REIT taxable income in accordance with the Coronavirus Aid, Relief, and Economic Security (CARES) Act. The federal NOL may be carried forward indefinitely. Other limitations may apply to our ability to use our NOL to offset taxable income. As of December 31, 2020, the Observatory TRS had a federal, state, and local income tax receivable of $8.1 million due to a NOL for the year ended December 31, 2020. Under special provisions of the CARES Act, the NOL can be carried back five years for federal income tax purposes. Due to limitations on the use of net operating loss carrybacks for state and local tax, the Observatory TRS will carry forward $3.8 million of NOL to offset future taxable income, if any. The state and local NOL can be carried forward for up to 20 years. We apply provisions for measuring and recognizing tax benefits associated with uncertain income tax positions. Penalties and interest, if incurred, would be recorded as a component of income tax expense. As of December 31, 2020 and 2019, we do not have a liability for uncertain tax positions. As of December 31, 2020, the tax years ended December 31, 2017 through December 31, 2020 remain open for an audit by the Internal Revenue Service, state or local authorities. Share-Based Compensation Share-based compensation for market 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 stated vesting period, which is generally three or four years, depending on retirement eligibility. 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 or four years, or (ii) the period from the date of grant to the date the employee becomes retirement eligible, which may occur upon grant. The determination of fair value of these awards is subjective and involves significant estimates and assumptions including expected volatility of our stock, expected dividend yield, expected term, and assumptions of whether these awards will achieve parity with other operating partnership units or achieve performance thresholds. We believe that the assumptions and estimates utilized are appropriate based on the information available to management at the time of grant. 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, repositioning and disposition of our 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 different marketing strategies. We account for intersegment sales and transfers as if the sales or transfers were to third parties, that is, at current market prices. For more information about our segments, refer to “Financial Statements-Note 12-Segment Reporting” in this Annual Report on Form 10-K. 65 Accounting Standards Update Reference is made to Note 2 in the accompanying consolidated financial statements for information about recently issued and recently adopted accounting standards. 66 ITEM 7A. 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. Market risk refers to the risk of loss from adverse changes in market prices and interest rates. One of the principal market risks facing us is interest rate risk on our variable rate indebtedness. As of December 31, 2020, our floating rate debt of $125.0 million represented 2.6% of our total enterprise value. Subject to maintaining our qualification as a REIT for U.S. federal income tax purposes, we may mitigate the risk of interest rate volatility through the use of hedging instruments, such as interest rate swap agreements and interest rate cap agreements. Our primary objectives when undertaking hedging transactions and derivative positions will be to reduce our floating rate exposure and to fix a portion of the interest rate for anticipated financing and refinancing transactions. This in turn will reduce the risk that the variability of cash flows will impose on floating rate debt. However, we can provide no assurances that our efforts to manage interest rate volatility will successfully mitigate the risks of such volatility on our portfolio. We are not subject to foreign currency risk. We are exposed to interest rate changes primarily on our unsecured revolving credit facility and debt refinancings. Our objectives with respect to interest rate risk are to limit the impact of interest rate changes on operations and cash flows, and to lower our overall borrowing costs. To achieve these objectives, we may borrow at fixed rates and may enter into derivative financial instruments such as interest rate swaps or caps in order to mitigate our interest rate risk on a related floating rate financial instrument. We do not enter into derivative or interest rate transactions for speculative purposes. As of December 31, 2020, we have an interest rate LIBOR swap agreement with an aggregate notional value of $265.0 million, which fixes the LIBOR interest rate at 2.1485% and matures on August 24, 2022. This interest rate swap has been designated as a cash flow hedge and is deemed highly effective with a fair value of ($8.8) million which is included in accounts payable and accrued expenses on the consolidated balance sheet as of December 31, 2020. Based on our variable balances, interest expense would have increased by approximately $1.3 million for the year ended December 31, 2020, if short-term interest rates had been 1% higher. As of December 31, 2020, the weighted average interest rate on the $2.0 billion of fixed-rate indebtedness outstanding was 3.91% per annum, each with maturities at various dates through March 17, 2035. As of December 31, 2020, the fair value of our outstanding debt was approximately $2.2 billion which was approximately $101.5 million more than the historical 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. In July 2017, the Financial Conduct Authority (“FCA”) that regulates LIBOR announced it intends to stop compelling banks to submit rates for the calculation of LIBOR after 2021. As a result, the Federal Reserve Board and the Federal Reserve Bank of New York organized the Alternative Reference Rates Committee ("ARRC"), which identified the Secured Overnight Financing Rate ("SOFR") as its preferred alternative rate for USD LIBOR in derivatives and other financial contracts. Subsequently, in November 2020, the Intercontinental Exchange (“ICE”) Benchmark Administration Limited (“IBA”), the administrator of LIBOR, announced that it would consult on its intention to cease the publication of the one-week and two- month USD LIBOR settings immediately following December 31, 2021, and the remaining USD LIBOR settings immediately following the LIBOR publication on June 30, 2023. We are not able to predict when LIBOR will cease to be available or when there will be sufficient liquidity in the SOFR markets. Any changes adopted by the FCA or other governing bodies in the method used for determining LIBOR may result in a sudden or prolonged increase or decrease in reported LIBOR. If that were to occur, our interest payments could change. In addition, uncertainty about the extent and manner of future changes may result in interest rates and/or payments that are higher or lower than if LIBOR were to remain available in its current form. We have contracts that are indexed to LIBOR and are monitoring and evaluating the related risks, which include interest on loans and amounts received and paid on derivative instruments. These risks arise in connection with transitioning contracts to an alternative rate, including any resulting value transfer that may occur, and are likely to vary by contract. The value of loans or derivative instruments tied to LIBOR, as well as interest rates on our unsecured revolving credit facility and our unsecured term loan facilities and the swap rate for our interest rate swap, may also be impacted if LIBOR is limited or discontinued. For some instruments the method of transitioning to an alternative reference rate may be challenging, especially if we cannot agree with the respective counterparty about how to make the transition. 67 While we expect LIBOR to be available in substantially its current form until at least the end of 2021, it is possible that LIBOR will become unavailable prior to that point. This could result, for example, if sufficient banks decline to make submissions to the LIBOR administrator. In that case, the risks associated with the transition to an alternative reference rate will be accelerated and magnified. Alternative rates and other market changes related to the replacement of LIBOR, including the introduction of financial products and changes in market practices, may lead to risk modeling and valuation challenges, such as adjusting interest rate accrual calculations and building a term structure for an alternative rate. The introduction of an alternative rate also may create additional basis risk and increased volatility as alternative rates are phased in and utilized in parallel with LIBOR. Adjustments to systems and mathematical models to properly process and account for alternative rates will be required, which may strain the model risk management and information technology functions and result in substantial incremental costs for the company. Our exposures to market risk have not changed materially since December 31, 2020. ITEM 8. FINANCIAL STATEMENTS AND SUPPLEMENTARY DATA The financial statements beginning on Page F-1 of this Annual Report on Form 10-K are incorporated herein by reference. ITEM 9. CHANGES IN AND DISAGREEMENTS WITH ACCOUNTANTS ON ACCOUNTING AND FINANCIAL DISCLOSURE None. ITEM 9A. 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 our Chief Executive Officer and Principal 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. As of December 31, 2020, 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 Chief Executive Officer and Principal 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 Chief Executive Officer and Principal Financial Officer concluded, as of that time, that our disclosure controls and procedures were effective in ensuring that information required to be disclosed by us in reports filed or submitted under the Exchange Act (i) is processed, recorded, summarized and reported within the time periods specified in the SEC’s rules and forms and (ii) is accumulated and communicated to our management, including our Chief Executive Officer and our Principal Financial Officer, as appropriate to allow for timely decisions regarding required disclosure. Changes in Internal Control Over Financial Reporting No significant changes to our internal control over financial reporting 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. 68 (a) Management's Report on Internal Control Over Financial Reporting Management of Empire State Realty Trust, Inc. is responsible for establishing and maintaining adequate internal control over financial reporting, as such term is defined in the Securities Exchange Act of 1934 Rule 13(a)-15(f). Under the supervision and with the participation of our management, including our Chief Executive Officer and Principal Financial Officer, we conducted an evaluation of the effectiveness of our internal control over financial reporting as of December 31, 2020 as required by the Securities Exchange Act of 1934 Rule 13(a)-15(c). In making this assessment, we used the criteria set forth in the framework in Internal Control–Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission (the "COSO criteria"). Based on our evaluation under the COSO criteria, our management concluded that our internal control over financial reporting was effective as of December 31, 2020 to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external reporting purposes in accordance with U.S. generally accepted accounting principles. Ernst & Young LLP, an independent registered public accounting firm that audited our Financial Statements included in this Annual Report, has issued an attestation report on our internal control over financial reporting as of December 31, 2020, which appears in paragraph (b) of this Item 9A. (b) Attestation report of the independent registered public accounting firm Report of Independent Registered Public Accounting Firm To the Shareholders and the Board of Directors of Empire State Realty Trust, Inc. Opinion on Internal Control Over Financial Reporting We have audited Empire State Realty Trust, Inc.’s internal control over financial reporting as of December 31, 2020, based on criteria established in Internal Control— Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (2013 framework) (the COSO criteria). In our opinion, Empire State Realty Trust, Inc. (the Company) maintained, in all material respects, effective internal control over financial reporting as of December 31, 2020, based on the COSO criteria. We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (PCAOB), the 2020 consolidated financial statements of the Company and our report dated February 26, 2021 expressed an unqualified opinion thereon. Basis for Opinion The Company’s management is responsible for maintaining effective internal control over financial reporting and for its assessment of the effectiveness of internal control over financial reporting included in the accompanying Management's Report on Internal Control over Financial Reporting. Our responsibility is to express an opinion on the Company’s internal control over financial reporting based on our audit. We are a public accounting firm registered with the PCAOB and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB. We conducted our audit in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether effective internal control over financial reporting was maintained in all material respects. Our audit included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, testing and evaluating the design and operating effectiveness of internal control based on the assessed risk, and performing such other procedures as we considered necessary in the circumstances. We believe that our audit provides a reasonable basis for our opinion. Definition and Limitations of Internal Control Over Financial Reporting A company’s internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A company’s internal control over financial reporting includes those policies and procedures that (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (2) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and 69 expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and (3) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the company’s assets that could have a material effect on the financial statements. Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate. /s/ Ernst & Young LLP New York, New York February 26, 2021 ITEM 9B.

Opinion on the Financial Statements We have audited the accompanying consolidated balance sheets of Empire State Realty Trust, Inc. (the Company) as of December 31, 2020 and 2019, the related consolidated statements of operations, comprehensive income (loss), shareholders' equity and cash flows for each of the three years in the period ended December 31, 2020, and the related notes and financial statement schedules listed in the Index at Item 15(a) (collectively referred to as the “consolidated financial statements”). In our opinion, the consolidated financial statements present fairly, in all material respects, the financial position of the Company at December 31, 2020 and 2019, and the results of its operations and its cash flows for each of the three years in the period ended December 31, 2020, in conformity with U.S. generally accepted accounting principles. We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (PCAOB), the Company's internal control over financial reporting as of December 31, 2020, based on criteria established in Internal Control-Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (2013 framework), and our report dated February 26, 2021, expressed an unqualified opinion thereon. Basis for Opinion These financial statements are the responsibility of the Company's management. Our responsibility is to express an opinion on the Company’s financial statements based on our audits. We are a public accounting firm registered with the PCAOB and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB. We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement, whether due to error or fraud. Our audits included performing procedures to assess the risks of material misstatement of the financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the financial statements. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the financial statements. We believe that our audits provide a reasonable basis for our opinion. Critical Audit Matter The critical audit matter communicated below is a matter arising from the current period audit of the financial statements that was communicated or required to be communicated to the audit committee and that: (1) relates to accounts or disclosures that are material to the financial statements and (2) involved our especially challenging, subjective or complex judgments. The communication of the critical audit matter does not alter in any way our opinion on the consolidated financial statements, taken as a whole, and we are not, by communicating the critical audit matter below, providing a separate opinion on the critical audit matter or on the accounts or disclosures to which it relates. F-1 Description of the matter How we addressed the matter in our audit Valuation of goodwill – observatory At December 31, 2020, the Company’s goodwill related to the observatory reporting unit was $227.5 million as disclosed in Note 3 to the consolidated financial statements. As discussed in Note 2 to the consolidated financial statements, goodwill is tested for impairment at least annually or more frequently if there are indicators of impairment. Given the adverse global economic and market conditions, the Company determined that interim impairment evaluations of goodwill were necessary for the observatory reporting unit and engaged a third-party valuation specialist, as a potential impairment existed. Similarly, the Company performed its annual impairment testing as of October 1, 2020. Auditing management’s goodwill impairment tests were complex due to the highly judgmental nature of the assumptions used. The fair value estimates were sensitive to significant assumptions such as revenue and cost projections, the weighted average cost of capital, and income tax considerations, which are affected by expectations about future market and economic conditions. We obtained an understanding, evaluated the design and tested the operating effectiveness of controls over the Company’s goodwill impairment process, including controls over management’s review of the significant assumptions described above. To test the implied fair value of the Company’s observatory reporting unit, we performed audit procedures that included, among other procedures, assessing the methodologies and testing the significant assumptions and underlying data used by the Company. We utilized internal valuation specialists in assessing the fair value methodologies applied and evaluating the reasonableness of certain assumptions selected by management.

Notes to Consolidated Financial Statements 1. Description of Business and Organization As used in these consolidated financial statements, unless the context otherwise requires, “we,” “us,” "our," the "company,” and "ESRT" mean Empire State Realty Trust, Inc. and its consolidated subsidiaries. We are a self-administered and self-managed real estate investment trust, or REIT, that owns, manages, operates, acquires and repositions office and retail properties in Manhattan and the greater New York metropolitan area. We were organized as a Maryland corporation on July 29, 2011. As of December 31, 2020, our total portfolio contained 10.1 million rentable square feet of office and retail space. We owned 14 office properties (including three long-term ground leasehold interest) encompassing approximately 9.4 million rentable square feet of office space. Nine of these properties are located in the midtown Manhattan market and encompass in the aggregate approximately 7.6 million rentable square feet of office space, including the Empire State Building. Our Manhattan office properties also contain an aggregate of 0.5 million rentable square feet of premier retail space on their ground floor and/ or lower levels. Our remaining five office properties are located in Fairfield County, Connecticut and Westchester County, New York, encompassing in the aggregate approximately 1.8 million rentable square feet. The majority of square footage for these five properties is located in densely populated metropolitan communities with immediate access to mass transportation. Additionally, we have entitled land at the Stamford Transportation Center in Stamford, Connecticut, adjacent to one of our office properties, that will support the development of an approximately 0.4 million rentable square foot office building and garage, which we refer to herein as Metro Tower. As of December 31, 2020, our portfolio also included four standalone retail properties located in Manhattan and two standalone retail properties located in the city center of Westport, Connecticut, encompassing 0.2 million rentable square feet in the aggregate. Empire State Realty OP, L.P. (the "Operating Partnership") holds substantially all of our assets and conducts substantially all of our business. As of December 31, 2020, we owned approximately 60.1% of the aggregate operating partnership units in our Operating Partnership. We, as the sole general partner in our Operating Partnership, have responsibility and discretion in the management and control of our Operating Partnership, and the limited partners in our Operating Partnership, in such capacity, have no authority to transact business for, or participate in the management activities of our Operating Partnership. Accordingly, our Operating Partnership has been consolidated by us. We elected to be taxed as a REIT and operate in a manner that we believe allows us to qualify as a REIT for federal income tax purposes commencing with our taxable year ended December 31, 2013. We have two entities that elected to be treated as taxable REIT subsidiaries, or TRSs, and are owned by our Operating Partnership. The TRSs, through several wholly owned limited liability companies, conduct third-party services businesses, which include the Empire State Building Observatory, cleaning services, cafeteria, restaurant and health clubs, and asset and property management services. 2. Summary of Significant Accounting Policies Basis of Presentation and Principles of Consolidation The accompanying consolidated financial statements, have been prepared in conformity with accounting principles generally accepted in the United States of America (“GAAP”) and with the rules and regulations of the Securities and Exchange Commission (the "SEC"), represent our assets and liabilities and operating results. The consolidated financial statements include our accounts and our wholly owned subsidiaries as well as our Operating Partnership and its subsidiaries. All significant intercompany balances and transactions have been eliminated in consolidation. 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 as well as whether the entity is a variable interest entity (“VIE”) and whether we are 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 F-9 consolidate the VIE. Empire State Realty Trust, Inc. has a variable interest in our Operating Partnership, Empire State Realty OP, L.P. and we are deemed to be the primary beneficiary. 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 consolidated balance sheets and in the consolidated statements of income by requiring earnings and other comprehensive income to be attributed to controlling and non-controlling interests. Accounting Estimates The preparation of the 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 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. Revenue Recognition Rental Revenue Rental revenue includes base rents that each tenant pays in accordance with the terms of its respective lease and is reported on a straight-line basis over the non-cancellable term of the lease which includes the effects of rent steps and rent abatements under the leases. In general, we commence rental revenue recognition when the tenant takes possession of the leased space or controls the physical use of the leased space and the leased space is substantially ready for its intended use. We account for all of our leases as operating leases. Deferred rent receivables, including free rental periods and leasing arrangements allowing for increased base rent payments, are accounted for in a manner that provides an even amount of fixed lease revenues over the respective non-cancellable lease terms. Differences between rental income recognized and amounts due under the respective lease agreements are recognized as an increase or decrease to deferred rent receivables. In addition to base rent, our tenants also generally will pay their pro rata share of increases in real estate taxes and operating expenses for the building over a base year. In some leases, in lieu of paying additional rent based upon increases in building operating expenses, the tenant will pay additional rent based upon increases in an index such as the Consumer Price Index over the index value in effect during a base year, or contain fixed percentage increases over the base rent to cover escalations. For Coronavirus 2019 (“COVID-19”) pandemic related rent deferral agreements, we will generally elect to record rental revenue and a receivable during the deferral period. We recognize rental revenue of acquired in-place above- and below-market leases at their fair values over the terms of the respective leases, including, for below-market leases, fixed option renewal periods, if any. Lease termination fees are recognized when the fees are determinable, tenant vacancy has occurred, collectability is reasonably assured, we have no continuing obligation to provide services to such former tenants and the payment is not subject to any conditions that must be met or waived. F-10 Observatory Revenue Revenues from the sale of Observatory tickets are recognized upon admission or ticket expirations. Deferred revenue related to unused and unexpired tickets as of December 31, 2020 and 2019 was $0.8 million and $2.7 million, respectively, and is included in deferred revenue and other liabilities on the consolidated balance sheets. Gains on Sale of Real Estate We record a gain on sale of real estate pursuant to provisions under Accounting Standards Codification (ASC) 610-20, Gains and Losses from the Derecognition of Nonfinancial Assets. Under ASC 610-20, we must first determine whether the transaction is a sale to a customer or non-customer. We do not sell real estate within the ordinary course of our business and therefore, expect that sale transactions will not be contracts with customers. We will next determine whether we would have a controlling financial interest in the property after the sale. If we determine that we do not have a controlling financial interest in the real estate, we would evaluate whether a contract exists under ASC 606 Revenue from Contracts with Customers and whether the buyer has obtained control of the asset that was sold. We recognize the full gain on sale of real estate when the derecognition criteria under ASC 610-20 have been met. Third-Party Management and Other Fees We earn revenue arising from contractual agreements with related party entities for asset and property management services. This revenue is recognized as the related services are performed under the respective agreements in place. Other Revenues and Fees Other revenues and fees includes parking income, legal, tax and insurance settlements, demand response energy use earnings and sales from our restaurant at the Empire State Building. Advertising and Marketing Costs Advertising and marketing costs are expensed as incurred. The expense for the years ended December 31, 2020, 2019, and 2018 was $7.4 million, $9.7 million and $8.9 million, respectively, and is included within operating expenses in our consolidated statements of operations. Real Estate Properties and Related Intangible Assets Land and buildings and improvements are recorded at cost less accumulated depreciation and amortization. The recorded cost includes cost of acquisitions, development and construction and tenant allowances and improvements. Expenditures for ordinary repairs and maintenance are charged to property operating expense as incurred. Significant replacements and betterments which improve or extend the life of the asset are capitalized. Tenant improvements which improve or extend the life of the asset are capitalized. If a tenant vacates its space prior to the contractual termination of its lease, the unamortized balance of any tenant improvements are written off if they are replaced or have no future value. For developed properties, direct and indirect costs that clearly relate to projects under development are capitalized. Costs include construction costs, professional services such as architectural and legal costs, capitalized interest and direct payroll costs. We begin capitalization when the project is probable. The assets relating to the project are stated at cost and are not depreciated. Once construction is completed and the assets are placed in service, the assets are reclassified to the appropriate asset class and depreciated in accordance with the useful lives as indicated below. Capitalization of interest ceases when the asset is ready for its intended use, which is generally near the date that a certificate of occupancy is obtained. Total capitalized interest for the years ended December 31, 2019 and 2018 was $1.4 million and $1.6 million, respectively. There was no capitalized interest for the year ended December 31, 2020. Depreciation and amortization are computed using the straight-line method for financial reporting purposes. Buildings and improvements are depreciated over the shorter of 39 years, the useful life, or the remaining term of any leasehold interest. Tenant improvement costs, which are included in building and improvements in the consolidated balance sheets, are depreciated over the shorter of (i) the related remaining lease term or (ii) the life of the improvement. Corporate equipment, which is included in “Other assets,” is depreciated over three to seven years. Acquisitions of properties are accounted for utilizing the acquisition method and accordingly the purchase cost is allocated to tangible and intangible assets and liabilities based on their fair values. The fair value of tangible assets acquired is determined by valuing the property as if it were vacant, applying methods similar to those used by independent appraisers of F-11 income-producing property. The resulting value is then allocated to land, buildings and improvements, and tenant improvements based on our determination of the fair value of these assets. The assumptions used in the allocation of fair values to assets acquired are based on our best estimates at the time of evaluation. Fair value is assigned to above-market and below-market leases based on the difference between (a) the contractual amounts to be paid by the tenant based on the existing lease and (b) our estimate of current market lease rates for the corresponding in-place leases, over the remaining terms of the in-place leases. Capitalized above-market lease amounts are amortized as a decrease to rental revenue over the remaining terms of the respective leases. Capitalized below-market lease amounts are amortized as an increase to rental revenue over the remaining terms of the respective leases. If a tenant vacates its space prior to the contractual termination of the lease and no rental payments are being made on the lease, any unamortized balance of the related intangible will be written off. The aggregate value of other acquired intangible assets consists of acquired ground leases and acquired in-place leases and tenant relationships. The fair value allocated to acquired in-place leases consists of a variety of components including, but not necessarily limited to: (a) the value associated with avoiding the cost of originating the acquired in-place leases (i.e. the market cost to execute a lease, including leasing commissions, if any); (b) the value associated with lost revenue related to tenant reimbursable operating costs estimated to be incurred during the assumed lease-up period (i.e. real estate taxes, insurance and other operating expenses); (c) the value associated with lost rental revenue from existing leases during the assumed lease- up period; and (d) the value associated with any other inducements to secure a tenant lease. We assess the potential for impairment of our long-lived assets, including real estate properties, annually or whenever events occur or a change in circumstances indicate that the recorded value might not be fully recoverable. We determine whether impairment in value has occurred by comparing the estimated future undiscounted cash flows expected from the use and eventual disposition of the asset to its carrying value. If the undiscounted cash flows do not exceed the carrying value, the real estate is adjusted to fair value and an impairment loss is recognized. Assets held for sale are recorded at the lower of cost or fair value less costs to sell. We do not believe that the value of any of our properties and intangible assets were impaired during the years ended December 31, 2020, 2019 and 2018. Cash and Cash Equivalents Cash and cash equivalents consist of cash on hand, government money markets, demand deposits with financial institutions and short-term liquid investments with original maturities of three months or less when purchased. Cash and cash equivalents held at major commercial banks may at times exceed the Federal Deposit Insurance Corporation limit. To date, we have not experienced any losses on our invested cash. Restricted Cash Restricted cash consists of amounts held for tenants in accordance with lease agreements such as security deposits and amounts held by lenders and/or escrow agents to provide for future real estate tax expenditures and insurance expenditures, tenant vacancy related costs and debt service obligations. Short-term Investments Short-term investments include time deposits with original maturities of greater than three months and remaining maturities of less than one year. Tenant and Other Receivables Tenant and other receivables, other than deferred rent receivable, are generally expected to be collected within one year. Deferred Leasing Costs Deferred leasing costs consist of fees incurred to initiate and renew leases, are amortized on a straight-line basis over the related lease term and the expense is included in depreciation and amortization in our consolidated statements of income. Upon the early termination of a lease, unamortized deferred leasing costs are charged to expense. F-12 Deferred Financing Costs Fees and costs incurred to obtain long-term financing have been deferred and are amortized as a component of interest expense in our consolidated statements of income over the life of the respective long-term financing on the straight-line method which approximates the effective interest method. Unamortized deferred financing costs are expensed when the associated debt is refinanced or repaid before maturity. Costs incurred in seeking debt, which do not close, are expensed in the period in which it is determined that the financing will not close. Equity Method Investments We account for investments under the equity method of accounting where we do not have control but have the ability to exercise significant influence. Under this method, investments are recorded at cost, and the investment accounts are adjusted for our share of the entities’ income or loss and for distributions and contributions. Equity income (loss) is allocated based on the portion of the ownership interest that is controlled by us. The agreements may designate different percentage allocations among investors for profits and losses; however, our recognition of the entity’s income or loss generally follows the entity’s distribution priorities, which may change upon the achievement of certain investment return thresholds. To the extent that we contributed assets to an entity, our investment in the entity is recorded at cost basis in the assets that were contributed to the entity. Upon contributing assets to an entity, we make a judgment as to whether the economic substance of the transaction is a sale. In accordance with the provisions of ASC 610-20, we will recognize a full gain on both the retained and sold portions of real estate contributed or sold to an entity by recognizing our new equity method investment interest at fair value. To the extent that the carrying amount of these investments on our combined balance sheets is different than the basis reflected at the entity level, the basis difference would be amortized over the life of the related asset and included in our share of equity in net income of the entity. On a periodic basis, we assess whether there are any indicators that the carrying value of our investments in entities may be impaired on an other than temporary basis. An investment is impaired only if management’s estimate of the fair value of the investment is less than the carrying value of the investment on an other than temporary basis. To the extent impairment has occurred, the loss shall be measured as the excess of the carrying value of the investment over the fair value of the investment. As of December 31, 2020 and 2019, we had no equity method investments. Goodwill Goodwill is tested annually for impairment and is tested for impairment more frequently if events and circumstances indicate that the asset might be impaired. An impairment loss is recognized to the extent that the carrying amount, including goodwill, exceeds the reporting unit’s fair value and the implied fair value of goodwill is less than the carrying amount of that goodwill. Non-amortizing intangible assets, such as trade names and trademarks, are subject to an annual impairment test based on fair value and amortizing intangible assets are tested whenever events or changes in circumstances indicate that the carrying amount may not be recoverable. In compliance with the requirements of authorities, we closed the Empire State Building Observatory on March 16, 2020 due to the COVID-19 pandemic and it remained closed until the 86th floor observation deck was reopened on July 20, 2020. The 102nd observation deck was reopened on August 24, 2020. The closure of our Observatory and subsequent reopening under international, national, and local travel restrictions and quarantines caused us during the quarter to choose to perform an impairment test related to goodwill. We engaged a third-party valuation consulting firm to perform the valuation process. The 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 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. Based upon the results of the goodwill impairment test of the stand-alone Observatory reporting unit, which is after the intercompany rent expense paid to the Real Estate reporting unit, we determined that the fair value of the Observatory reporting unit exceeded its carrying value by less than 5.0%. Many of the factors employed in determining whether or not goodwill is impaired are outside of our control and it is reasonably likely that F-13 assumptions and estimates will change in future periods. We will continue to assess the impairment of the Observatory reporting unit goodwill going forward and that continued assessment may again utilize a third-party valuation consulting firm. Fair Value Fair value is a market-based measurement, not an entity-specific measurement, and should be determined based on the assumptions that market participants would use in pricing the asset or liability. As a basis for considering market participant assumptions in fair value measurements, the FASB guidance establishes a fair value hierarchy that distinguishes between market participant assumptions based on market data obtained from sources independent of the reporting entity (observable inputs that are classified within levels one and two of the hierarchy) and the reporting entity's own assumptions about market participant assumptions (unobservable inputs classified within Level 3 of the hierarchy). The methodologies used for valuing financial instruments have been categorized into three broad levels as follows: Level 1 - Quoted prices in active markets for identical instruments. Level 2 - Valuations based principally on other observable market parameters, including: • • • Quoted prices in active markets for similar instruments; Quoted prices in less active or inactive markets for identical or similar instruments; Other observable inputs (such as risk free interest rates, yield curves, volatilities, prepayment speeds, loss severities, credit risks and default rates); and • Market corroborated inputs (derived principally from or corroborated by observable market data). Level 3 - Valuations based significantly on unobservable inputs, including: • • Valuations based on third-party indications (broker quotes or counterparty quotes) which were, in turn, based significantly on unobservable inputs or were otherwise not supportable; and Valuations based on internal models with significant unobservable inputs. These levels form a hierarchy. We follow this hierarchy for our financial instruments measured or disclosed at fair value on a recurring and nonrecurring basis and other required fair value disclosures. The classifications are based on the lowest level of input that is significant to the fair value measurement. We use the following methods and assumptions in estimating fair value disclosures for financial instruments. Cash and cash equivalents, restricted cash, short term investments, tenant and other receivables, prepaid expenses and other assets, deferred revenue, tenant security deposits, accounts payable and accrued expenses carrying values approximate their fair values due to the short term maturity of these instruments. 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 of our derivatives were classified as Level 2 of the fair value hierarchy. The fair value of our mortgage notes payable, senior unsecured notes - Series A, B, C, D, E, F, G and H, and unsecured term loan facilities 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 to us. Derivative Instruments We are exposed to the effect of interest rate changes and manage these risks by following policies and procedures including the use of derivatives. To manage exposure to interest rates, derivatives are used primarily to fix the rate on debt based on floating-rate indices. We also hedged our exposure to the variability in future cash flows for forecast transactions through June 30, 2020 (excluding forecast transactions related to the payment of variable interest on existing financial F-14 instruments). We record all derivatives on the balance sheet at fair value. We incorporate credit valuation adjustments to appropriately reflect both our own nonperformance risk and the respective counterparty’s nonperformance risk in the fair value measurements. We measure the credit risk of our derivative instruments that are subject to master netting agreements on a net basis by counterparty portfolio. For derivatives that qualify as cash flow hedges, we report the gain or loss on the derivative designated as a hedge as part of other comprehensive income (loss) and subsequently reclassify the gain or loss into income in the period that the hedged transaction affects income. Income Taxes We elected to be taxed as a REIT under sections 856 through 860 of the Internal Revenue Code of 1986, as amended, (the "Code"), commencing with the taxable year ended December 31, 2013 and believe we qualify as a REIT at December 31, 2020. REITs are subject to a number of organizational and operational requirements, including a requirement that 90% of ordinary “REIT taxable income” (as determined without regard to the dividends paid deduction or net capital gains) be distributed. As a REIT, we will generally not be subject to U.S. federal income tax to the extent that we meet the organizational and operational requirements and our distributions equal or exceed REIT taxable income. For all periods subsequent to the effective date of our REIT election, we have met the organizational and operational requirements and distributions have exceeded net taxable income. Accordingly, no provision has been made for federal and state income taxes. We have elected to treat ESRT Observatory TRS, L.L.C., our subsidiary which holds our observatory operations, and ESRT Holdings TRS, L.L.C., our subsidiary that holds our third party management, restaurant, cafeteria, health clubs and certain cleaning operations, as taxable REIT subsidiaries. Taxable REIT subsidiaries may participate in non-real estate activities and/or perform non-customary services for tenants and their operations are generally subject to regular corporate income taxes. Our taxable REIT subsidiaries accounts for its income taxes in accordance with GAAP, which includes an estimate of the amount of taxes payable or refundable for the current year and deferred tax liabilities and assets for the future tax consequences of events that have been recognized in our financial statements or tax returns. The calculation of the taxable REIT subsidiaries' tax provisions may require interpreting tax laws and regulations and could result in the use of judgments or estimates which could cause its recorded tax liability to differ from the actual amount due. Deferred income taxes reflect the net tax effects of temporary differences between the carrying amounts of assets and liabilities for financial reporting purposes and the amounts used for income tax purposes. The taxable REIT subsidiaries periodically assess the realizability of deferred tax assets and the adequacy of deferred tax liabilities, including the results of local, state, or federal statutory tax audits or estimates and judgments used. We apply provisions for measuring and recognizing tax benefits associated with uncertain income tax positions. Penalties and interest, if incurred, would be recorded as a component of income tax expense. As of December 31, 2020 and 2019, we do not have a liability for uncertain tax positions. As of December 31, 2020, the tax years ended December 31, 2017 through December 31, 2020 remain open for an audit by the Internal Revenue Service, state or local authorities. Share-Based Compensation Share-based compensation for market-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 stated vesting period, which is generally three or four years, depending on retirement eligibility. 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 or four 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 60 or 65, as applicable, and (ii) the date on which the employee has first completed ten years of continuous service with us or our affiliates. The determination of fair value of these awards is subjective and involves significant estimates and assumptions including expected volatility of our stock, expected dividend yield, expected term, and assumptions of whether these awards will achieve parity with other Operating Partnership units or achieve performance thresholds. We believe that the assumptions and estimates utilized are appropriate based on the information available to management at the time of grant. Per Share Data Basic and diluted earnings per share are computed based upon the weighted average number of shares outstanding during the respective period. Segment Reporting F-15 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, repositioning and disposition of our 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 different marketing strategies. We account for intersegment sales and rent as if the sales or rent were to third parties, that is, at current market prices. Recently Issued or Adopted Accounting Standards During April 2020, the Financial Accounting Standards Board ("FASB") staff issued a question and answer document (the “Lease Modification Q&A”) focused on the application of lease accounting guidance to lease concessions provided as a result of the COVID-19 global pandemic. Under existing lease guidance, the entity would have to determine, on a lease by lease basis, if a lease concession was the result of a new arrangement reached with the tenant, which would be accounted for under the lease modification framework, or if a lease concession was under the enforceable rights and obligations that existed in the original lease, which would be accounted for outside the lease modification framework. The Lease Modification Q&A provides entities with the option to elect to account for lease concessions as though the enforceable rights and obligations existed in the original lease. This election is only available when total cash flows resulting from the modified lease are substantially similar to the cash flows in the original lease. During March 2020, the FASB issued Accounting Standards Update ("ASU") 2020-04, Reference Rate Reform (Topic 848). ASU 2020-04 contains practical expedients for reference rate reform related activities that impact debt, leases, derivatives and other contracts. The guidance in ASU 2020-04 is optional and may be elected over time as reference rate reform activities occur. During the first quarter 2020, we elected to apply the hedge accounting expedients related to probability and the assessments of effectiveness for future LIBOR-indexed cash flows to assume that the index upon which future hedged transactions will be based matches the index on the corresponding derivatives. Application of these expedients preserves the presentation of derivatives consistent with past presentation. We continue to evaluate the impact of the guidance and may apply other elections as applicable as additional changes in the market occur. During January 2017, the FASB issued ASU No. 2017-04, Intangibles-Goodwill and Other (Topic 350): Simplifying the Test for Goodwill Impairment, which contain amendments that modify the concept of impairment from the condition that exists when the carrying amount of goodwill exceeds its implied fair value to the condition that exists when the carrying amount of a reporting unit exceeds its fair value. An entity no longer will determine goodwill impairment by calculating the implied fair value of goodwill by assigning the fair value of a reporting unit to all of its assets and liabilities as if that reporting unit had been acquired in a business combination. Because these amendments eliminate Step 2 from the goodwill impairment test, they should reduce the cost and complexity of evaluating goodwill for impairment. ASU No. 2017-04 should be applied on a prospective basis and the amendments adopted for the annual or any interim goodwill impairment tests in fiscal years beginning after December 15, 2019. Early adoption is permitted for interim or annual goodwill impairment tests performed on testing dates after January 1, 2017. We adopted this standard and related amendments on January 1, 2020 and such adoption did not have a material impact our consolidated financial statements. During June 2016, the FASB issued ASU No. 2016-13, Financial Instruments-Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments, which contains amendments that replace the incurred loss impairment methodology in current GAAP with a methodology that reflects expected credit losses and requires consideration of a broader range of reasonable and supportable information to inform credit loss estimates. During November 2018, the FASB issued ASU No. 2018-19, Codification Improvements to Topic 326, Financial Instruments - Credit Losses, which clarifies that receivables arising from operating leases are not within the scope of Topic 326. Instead, impairment of receivables arising from operating leases should be accounted in accordance with ASU No. 2016-02, Leases (Topic 842). ASU No. 2016-13 and ASU No. 2018-19 will be effective for fiscal years beginning after December 15, 2019, including interim periods within those fiscal years. Earlier adoption as of the fiscal years beginning after December 15, 2018, including interim periods within those fiscal years, is permitted. The amendments must be adopted through a cumulative-effect adjustment to retained earnings as of the beginning of the first reporting period in which the guidance is effective (that is, a modified retrospective approach). We adopted these standards on January 1, 2020 and such adoption did not have a material impact our consolidated financial statements. F-16 3. Deferred Costs, Acquired Lease Intangibles and Goodwill Deferred costs, net, consisted of the following at December 31, 2020 and 2019 (amounts in thousands): Leasing costs Acquired in-place lease value and deferred leasing costs Acquired above-market leases Less: accumulated amortization 2020 2019 $ 203,905 $ 181,336 40,398 425,639 (223,918) Total deferred costs, net, excluding net deferred financing costs $ 201,721 $ 199,033 200,296 49,213 448,542 (224,598) 223,944 At December 31, 2020 and 2019, $2.1 million and $4.2 million, respectively, of net deferred financing costs associated with the unsecured revolving credit facility was included in deferred costs, net on the consolidated balance sheets. Amortization expense related to deferred leasing and acquired deferred leasing costs was $24.8 million, $24.5 million, and $26.3 million, for the years ended December 31, 2020, 2019, and 2018, respectively. Amortization expense related to acquired lease intangibles was $7.6 million, $10.9 million and $12.1 million for the years ended December 31, 2020, 2019 and 2018, respectively.

The remaining weighted-average amortization period as of December 31, 2020 is 23.6 years, 3.9 years, 3.6 years and 3.7 years for below-market ground leases, in-place leases and deferred leasing costs, above-market leases and below-market leases, respectively. We expect to recognize amortization expense and rental revenue from the acquired intangible assets and liabilities as follows (amounts in thousands): For the year ending: 2021 2022 2023 2024 2025 Thereafter Future Ground Rent Amortization Future Amortization Expense Future Rental Revenue $ 7,831 7,831 7,831 7,831 7,831 305,580 $ 10,977 $ 10,175 9,622 7,757 6,652 16,740 2,850 3,169 3,129 2,566 2,558 4,082 $ 344,735 $ 61,923 $ 18,354 As of December 31, 2020, we had goodwill of $491.5 million. In 2013, we acquired the interests in Empire State Building Company, L.L.C. and 501 Seventh Avenue Associates, L.L.C. for an amount in excess of their net tangible and identified intangible assets and liabilities and as a result we recorded goodwill related to the transaction. Goodwill was allocated $227.5 million to the observatory operations of the Empire State Building, $250.8 million to Empire State Building, and $13.2 million to 501 Seventh Avenue. F-17 In compliance with the requirements of authorities, we closed the Empire State Building Observatory on March 16, 2020 due to the COVID-19 pandemic and it remained closed until the 86th floor observation deck was reopened on July 20, 2020. The 102nd observation deck was reopened on August 24, 2020. The closure of our Observatory and subsequent reopening under international, national, and local travel restrictions and quarantines caused us during the quarter to choose to perform an impairment test related to goodwill. We engaged a third-party valuation consulting firm to perform the valuation process. The 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 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. Based upon the results of the goodwill impairment test of the stand-alone Observatory reporting unit, which is after the intercompany rent expense paid to the Real Estate reporting unit, we determined that the fair value of the Observatory reporting unit exceeded its carrying value by less than 5.0%. 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 and that continued assessment may again utilize a third-party valuation consulting firm. F-18 4.

Mortgage Debt During November 2020, we closed on a $180.0 million mortgage loan for 250 West 57th Street. This new interest- only loan bears a fixed interest rate of 2.83% and matures in December 2030. Unsecured Revolving Credit and Term Loan Facilities On March 19, 2020, through our Operating Partnership, we entered into an amendment to an existing credit agreement with the lenders party thereto, Bank of America, N.A., as administrative agent, and Bank of America, Wells Fargo Bank, National Association and Capital One, National Association, as the letter of credit issuers party thereto. The amendment amends the amended and restated senior unsecured revolving credit and term loan facility, entered into as of August 29, 2017, with Bank of America, N.A., as administrative agent, Merrill Lynch, Pierce, Fenner & Smith Incorporated and Wells Fargo Securities, LLC as Joint Lead Arrangers and Joint Bookrunners, Wells Fargo, National Association and Capital One, National Association, as co-syndication agents, and the lenders party thereto. This new amended and restated senior unsecured revolving credit and term loan facility (the "Credit Facility") is in the original principal amount of up to $1.315 billion, which consists of a $1.1 billion revolving credit facility and a $215.0 million term loan facility. We borrowed the term loan facility in full at closing. We may request the Credit Facility be increased through one or more increases in the revolving credit facility or one or more increases in the term loan facility or the addition of new pari passu term loan tranches, for a maximum aggregate principal amount not to exceed $1.75 billion. As of December 31, 2020, we had no borrowings under the revolving credit facility and $215.0 million outstanding under the term loan facility. The initial maturity of the unsecured revolving credit facility is August 2021. We have the option to extend the initial term for up to two additional 6-month periods, subject to certain conditions, including the payment of an extension fee equal to 0.0625% and 0.075% of the then outstanding commitments under the unsecured revolving credit facility on the first and the second extensions, respectively. We recently began a process to recast the credit facility and exercise an extension option. The term loan facility matures in March 2025. We may prepay the loans under the Credit Facility at any time in whole or in part, subject to reimbursement of the lenders’ breakage and redeployment costs in the case of prepayment of Eurodollar Rate borrowings. F-20 On March 19, 2020, we entered into a senior unsecured term loan facility (the “Term Loan Facility”) with Wells Fargo Bank, National Association, as administrative agent, Wells Fargo Securities, LLC as sole bookrunner, Wells Fargo Securities, LLC, Capital One, National Association, U.S. Bank National Association and SunTrust Robinson Humphrey, Inc. as Joint Lead Arrangers, Capital One, National Association, as syndication agent, U.S. Bank National Association and Truist Bank, as documentation agents, and the lenders party thereto. The Term Loan Facility is in the original principal amount of $175 million which we borrowed in full at closing. We may request the 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 December 31, 2020, our borrowings amounted to $175.0 million under the Term Loan Facility. The Term Loan Facility matures on December 31, 2026. We may prepay loans under the Term Loan Facility at any time in whole or in part, subject to reimbursement of the lenders’ breakage and redeployment costs in the case of prepayment of Eurodollar rate borrowings and, if the prepayment occurs on or before December 31, 2021, a prepayment fee. If the prepayment occurs on or prior to December 31, 2020, the prepayment fee is equal to 2.0% of the principal amount prepaid, and if the prepayment occurs after December 31, 2020 but on or prior to December 31, 2021, the prepayment fee is equal to 1.0% of the principal amount prepaid. The terms of both the Credit Facility and the 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. It also requires compliance with financial ratios including a maximum leverage ratio, a maximum secured leverage ratio, a minimum fixed charge coverage ratio, a minimum unencumbered interest coverage ratio, and a maximum unsecured leverage ratio. The agreement also contains customary events of default (subject in certain cases to specified cure periods), including but not limited to non-payment, breach of covenants, representations or warranties, cross defaults, bankruptcy or other insolvency events, judgments, ERISA events, invalidity of loan documents, loss of real estate investment trust qualification, and occurrence of a change of control. As of December 31, 2020, we were in compliance with the covenants under the Credit Facility and the Term Loan Facility. Senior Unsecured Notes Exchangeable During August 2014, we issued $250.0 million principal amount of 2.625% Exchangeable Senior Notes (“2.625% Exchangeable Senior Notes”) due August 15, 2019. The 2.625% Exchangeable Senior Notes were exchangeable into cash, shares of Class A common stock or a combination of cash and shares of Class A common stock, at our election. On August 15, 2019, we settled the principal amount of the 2.625% Exchangeable Senior Notes in cash. For the years ended December 31, 2019 and 2018, total interest expense related to the 2.625% Exchangeable Senior Notes was $6.1 million and $9.9 million, respectively, consisting of (i) contractual interest expense of $4.1 million and $6.6 million, respectively, (ii) additional non-cash interest expense of $1.6 million and $2.7 million, respectively, related to the accretion of the debt discount, and (iii) amortization of deferred financing costs of $0.4 million and $0.6 million, respectively. Senior Unsecured Notes On March 17, 2020, through the Operating Partnership, we entered into an agreement to issue and sell an aggregate $175 million of senior unsecured notes, consisting of (a) $100 million aggregate principal amount of 3.61% Series G Senior Notes due March 17, 2032 (the “Series G Notes”) and (b) $75 million aggregate principal amount of 3.73% Series H Senior Notes due March 17, 2035 (the “Series H Notes”). The issue price for the Series G and H Notes was 100% of the aggregate principal amount thereof. The terms of the Series A, B, C, D, E, F, G and H Notes agreements include customary covenants, including limitations on liens, investment, distributions, debt, fundamental changes, and transactions with affiliates and require certain customary financial reports. It also requires compliance with financial ratios including a maximum leverage ratio, a maximum secured leverage ratio, a minimum fixed charge coverage ratio, a minimum unencumbered interest coverage ratio, and a maximum unsecured leverage ratio. The agreement also contains customary events of default (subject in certain cases to specified cure periods), including but not limited to non-payment, breach of covenants, representations or warranties, cross defaults, bankruptcy or other insolvency events, judgments, ERISA events, the occurrence of certain change of control F-21 transactions and loss of real estate investment trust qualification. As of December 31, 2020, we were in compliance with the covenants under the outstanding Senior Unsecured Notes. 5. Accounts Payable and Accrued Expenses Accounts payable and accrued expenses consist of the following as of December 31, 2020 and 2019 (amounts in thousands): Accrued capital expenditures Accounts payable and accrued expenses Interest rate swap agreements liability Accrued interest payable Due to affiliated companies 2020 2019 $ 58,057 $ 32,309 8,849 3,219 769 90,910 35,084 13,330 3,699 763 Total accounts payable and accrued expenses $ 103,203 $ 143,786 6. 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 December 31, 2020, the fair value of derivatives in a net liability position, which includes accrued interest but excludes any adjustment for nonperformance risk, related to these agreements was $8.9 million. If we had breached any of these provisions at December 31, 2020, we could have been required to settle our obligations under the agreements at their termination value of $8.9 million. As of December 31, 2020 and 2019, we had interest rate LIBOR swaps with an aggregate notional value of $265.0 million and $390.0 million, respectively. The notional value does not represent exposure to credit, interest rate or market risks. As of December 31, 2020 and 2019, the fair value of our derivative instruments amounted to ($8.8 million) and ($13.3 million), respectively, which is included in accounts payable and accrued expenses on the 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. As of December 31, 2020 and 2019, our cash flow hedges are deemed highly effective and for the years ended December 31, 2020 and 2019, net unrealized losses of $10.5 million and $20.6 million, respectively, are reflected in the consolidated statements of comprehensive income (loss) relating to both active and terminated cash flow hedges of interest rate risk. Amounts reported in accumulated other comprehensive income (loss) related to derivatives will be reclassified to interest expense as interest payments are made on the debt. We estimate that $11.5 million net loss of the current balance held in accumulated other comprehensive loss will be reclassified into interest expense within the next 12 months. F-22 The table below summarizes the terms of agreements and the fair values of our derivative financial instruments as of December 31, 2020 and 2019 (dollar amounts in thousands): Derivative Notional Amount Receive Rate Pay Rate Effective Date Expiration Date Asset Liability Asset Liability December 31, 2020 December 31, 2019 Interest rate swap $ 265,000 Interest rate swap 125,000 1 Month LIBOR 3 Month LIBOR 2.1485 % August 31, 2017 August 24, 2022 $ — $ (8,849) $ — $ (4,247) 2.9580 % July 1, 2019 July 1, 2026 — — — (9,083) $ — $ (8,849) $ — $ (13,330) During the year ended December 31, 2020, we terminated the $125.0 million swap and paid a settlement fee of $20.3 million.

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 following tables summarize the carrying and estimated fair values of our financial instruments as of December 31, 2020 and 2019 (amounts in thousands): Carrying Value December 31, 2020 Estimated Fair Value Total Level 1 Level 2 Level 3 Interest rate swaps included in accounts payable and accrued expenses $ 8,849 $ 8,849 $ Mortgage notes payable 775,929 808,294 Senior unsecured notes - Series A, B, C, D, E, F, G and H Unsecured term loan facilities 973,159 387,561 1,039,857 390,000 — — — — $ 8,849 $ — — — — 808,294 1,039,857 390,000 F-23 Interest rate swaps included in accounts payable and accrued expenses Mortgage notes payable Senior unsecured notes - Series A, B, C, D, E and F Unsecured term loan facility Carrying Value 13,330 605,542 798,392 264,640 December 31, 2019 Estimated Fair Value Total Level 1 Level 2 Level 3 13,330 629,609 843,394 265,000 — — — — 13,330 — — — — 629,609 843,394 265,000 Disclosure about the fair value of financial instruments is based on pertinent information available to us as of December 31, 2020 and 2019. Although we are not aware of any factors that would significantly affect the reasonable fair value amounts, such amounts have not been comprehensively revalued for purposes of these financial statements since that date and current estimates of fair value may differ significantly from the amounts presented herein. 7. Leases Lessor We lease various spaces to tenants over terms ranging from one to 21 years. Certain leases have renewal options for additional terms. 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 December 31, 2020 and 2019 consolidated statements of operations as rental revenue and in our December 31, 2018 consolidated statement of operations as tenant expense reimbursement. Rental revenue includes fixed and variable payments. Fixed payments primarily relate to base rent and variable payments primarily relate to tenant expense reimbursements for certain property operating costs. The components of rental revenue for the year ended December 31, 2020 and 2019 are as follows (amounts in thousands): Fixed payments Variable payments Total rental revenue Year Ended December 31, 2020 2019 $ $ 496,515 $ 66,556 563,071 $ 510,799 75,615 586,414 As of December 31, 2020, we were entitled to the following future contractual minimum lease payments (excluding operating expense reimbursements) on non-cancellable operating leases to be received which expire on various dates through 2038 (amounts in thousands): 2021 2022 2023 2024 2025 Thereafter $ $ 492,574 489,185 468,877 431,204 391,228 1,846,423 4,119,491 The above future minimum lease payments exclude tenant recoveries, amortization of deferred rent receivables and the net accretion of above-below-market lease intangibles. Some leases are subject to termination options generally upon payment of a termination fee. The preceding table is prepared assuming such options are not exercised. 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 $29.1 million and lease liabilities of $29.1 million in our consolidated balance sheet as of December 31, 2020. 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 F-24 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. We make payments under ground leases related to three of our properties. 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 ASU 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 December 31, 2020 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 December 31, 2020 was 49.3 years. As of December 31, 2020, the following table summarizes our future minimum lease payments with the amounts discounted by our incremental borrowing rates to calculate the lease liabilities of our leases (amounts in thousands): 2021 2022 2023 2024 2025 Thereafter Total undiscounted lease payments Present value discount Ground lease liabilities 8. Commitments and Contingencies Legal Proceedings Litigation $ $ 1,518 1,518 1,518 1,518 1,518 65,262 72,852 (43,748) 29,104 Except as described below, as of December 31, 2020, 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 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 initial public offering of our company (the "Offering"), 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) alleges breach of fiduciary duty and related claims in connection with the Offering and formation transactions and seeks monetary damages and declaratory relief. Claimants had opted out of a prior class action bringing similar claims that was 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 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 statement of operations for the nine months ended September 30, 2020. Respondents believe that such award in favor of the Claimants is entirely without merit, and have sought vacatur of that portion of the award. In addition, certain of the Claimants have stated in the federal court action that they intend to pursue claims in that case against Respondents. Respondents believe that any such claims are meritless. 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. F-25 Unfunded Capital Expenditures At December 31, 2020, we estimate that we will incur approximately $121.9 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, additional property level mortgage financings, our unsecured credit facility, 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 December 31, 2020, 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. Real Estate Investments Our properties are located in Manhattan, New York; Fairfield County, Connecticut; and Westchester County, New York. The latter locations are suburbs of the city of New York. The ability of the tenants to honor the terms of their respective leases is dependent upon the economic, regulatory and social factors affecting the markets in which the tenants operate. We perform ongoing credit evaluations of our tenants for potential credit losses. Tenant Credit Evaluations Our investments in real estate properties are subject to risks incidental to the ownership and operation of commercial real estate. These risks include, among others, the risks normally associated with changes in general economic conditions, trends in the real estate industry, creditworthiness of tenants, competition of tenants and customers, changes in tax laws, interest rate levels, the availability and cost of financing, and potential liability under environmental and other laws. We may require tenants to provide some form of credit support such as corporate guarantees and/or other financial guarantees and we perform ongoing credit evaluations of tenants. Although the tenants operate in a variety of industries, to the extent we have a significant concentration of rental revenue from any single tenant, the inability of that tenant to make its lease payments could have an adverse effect on our company. Major Customers and Other Concentrations For the year ended December 31, 2020, other than two tenants who accounted for 6.9% and 3.5% of rental revenues, no other tenant in our portfolio accounted for more than 2.0% of rental revenues. For the year ended December 31, 2019, other than three tenants who accounted for 6.8%, 3.2% and 3.2% of rental revenues, no other tenant in our portfolio accounted for more than 2.0% of rental revenues. For the year ended December 31, 2018, other than five tenants who accounted for 6.0%, 3.1%, 2.9%, 2.0% and 2.0% of rental revenues, no other tenant in our portfolio accounted for more than 2.0% of rental revenues. For the years ended December 31, 2020, 2019 and 2018, the six properties listed below accounted for the indicated percentage of total rental revenues. No other property accounted for more than 5.0% of total rental revenues. Empire State Building One Grand Central Place 111 West 33rd Street 1400 Broadway 250 West 57th Street First Stamford Place Asset Retirement Obligations F-26 Year Ended December 31, 2020 2019 2018 32.8 % 12.4 % 10.5 % 8.0 % 5.7 % 5.4 % 32.9 % 12.3 % 9.9 % 7.1 % 5.5 % 5.4 % 31.9 % 12.8 % 9.3 % 7.1 % 5.2 % 5.9 % 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 December 31, 2020, 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 Certain of our properties have been inspected for soil contamination due to pollutants, which may have occurred prior to our ownership of these properties or subsequently in connection with its development and/or its use. Required remediation to such properties has been completed and, as of December 31, 2020, 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. We expect that resolution of the environmental matters relating to the above will not have a material impact on our business, assets, consolidated and combined financial condition, results of operations or liquidity. 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. 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. Multiemployer Pension and Defined Contribution Plans We contribute to a number of multiemployer defined benefit pension plans under the terms of collective bargaining agreements that cover our union-represented employees. The risks of participating in these multiemployer plans are different from single-employer plans in the following respects: • • • Assets contributed to the multiemployer plan by one employer may be used to provide benefits to employees of other participating employers. If a participating employer stops contributing to the plan, the unfunded obligations of the plan may be borne by the remaining participating employers. If we choose to stop participating in some of our multiemployer plans, we may be required to pay those plans an amount based on the underfunded status of the plan, referred to as a withdrawal liability. We participate in various unions. The union in which we have significant employees and costs is 32BJ. 32BJ We participate in the Building Service 32BJ, ("Union"), Pension Plan and Health Plan. The Pension Plan is a multi- employer, non-contributory defined benefit pension plan that was established under the terms of collective bargaining agreements between the Service Employees International Union, Local 32BJ, the Realty Advisory Board on Labor Relations, Inc. and certain other employers. This Pension Plan is administered by a joint board of trustees consisting of union trustees and employer trustees and operates under employer identification number 13-1879376. The Pension Plan year runs from July 1 to June 30. Employers contribute to the Pension Plan at a fixed rate on behalf of each covered employee. Separate actuarial information regarding such pension plans is not made available to the contributing employers by the union administrators or trustees, since the plans do not maintain separate records for each reporting unit. However, on September 28, 2018, September 27, 2019 and September 28, 2020, the actuary certified that for the plan years beginning July 1, 2018, July 1, 2019 and July 1, 2020, respectively, the Pension Plan was in critical status under the Pension Protection Act of 2006. The Pension Plan trustees adopted a rehabilitation plan consistent with this requirement. For each of the years ended June 30, F-27 2020, 2019 and 2018, the Pension Plan received contributions from employers totaling $291.3 million, $290.1 million and $272.3 million, respectively. The Health Plan was established under the terms of collective bargaining agreements between the Union, the Realty Advisory Board on Labor Relations, Inc. and certain other employers. The Health Plan provides health and other benefits to eligible participants employed in the building service industry who are covered under collective bargaining agreements, or other written agreements, with the Union. The Health Plan is administered by a Board of Trustees with equal representation by the employers and the Union and operates under employer identification number 13-2928869. The Health Plan receives contributions in accordance with collective bargaining agreements or participation agreements. Generally, these agreements provide that the employers contribute to the Health Plan at a fixed rate on behalf of each covered employee. For the years ended June 30, 2020, 2019 and 2018, the Health Plan received contributions from employers totaling $1.6 billion, $1.5 billion and $1.4 billion, respectively. Term of Collective Bargaining Agreement The most recent collective bargaining agreement for Local 32BJ commenced from January 1, 2020 and runs through December 31, 2023. Contributions Contributions we made to the multi-employer plans for the years ended December 31, 2020, 2019 and 2018 are included in the table below (amounts in thousands): Benefit Plan Pension Plans (pension and annuity)* Health Plans** Other*** Total plan contributions For the Year Ended December 31, 2019 2018 2020 $ $ 2,383 6,873 416 9,672 $ 3,418 $ 10,055 641 14,114 $ $ 3,327 9,373 814 13,514 * Pension plans include $0.8 million, $1.0 million and $1.0 million for the years ended 2020, 2019 and 2018, respectively, to multiemployer plans not discussed above. ** Health plans include $1.4 million, $1.8 million and $1.6 million for the years ended 2020, 2019 and 2018, respectively, to multiemployer plans not discussed above. *** Other consists of union costs which were not itemized between pension and health plans. Other includes $0.3 million, $0.4 million and $0.2 million for the years ended 2020, 2019 and 2018, respectively, in connection with other multiemployer plans not discussed above. The decrease in plan contributions in 2020 is mainly due to the reduction in payroll levels as a result of the COVID-19 pandemic. Benefit plan contributions are included in operating expenses in our consolidated statements of operations. 9. Equity Shares and Units An operating partnership unit ("OP Unit") and a share of our common stock have essentially the same economic characteristics as they receive the same per unit profit distributions of the Operating Partnership. On the one-year anniversary of issuance, an OP Unit may be tendered for redemption for cash; however, we have sole and absolute discretion, and sufficient authorized common stock, to exchange OP Units for shares of common stock on a one-for-one basis instead of cash. On May 16, 2019, the Empire State Realty Trust, Inc. Empire State Realty OP, L.P. 2019 Equity Incentive Plan (“2019 Plan”) was approved by our shareholders. The 2019 Plan provides for grants to directors, employees and consultants of our company and operating partnership, including options, restricted stock, restricted stock units, stock appreciation rights, performance awards, dividend equivalents and other equity-based awards. An aggregate of approximately 11.0 million shares of our common stock are authorized for issuance under awards granted pursuant to the 2019 Plan. We will not issue any new equity awards under the First Amended and Restated Empire State Realty Trust, Inc. and Empire State Realty OP, L.P. 2013 Equity Incentive Plan ("2013 Plan", and collectively with the 2019 Plan, "the Plans"). The shares of Class A common stock underlying any awards under the 2019 Plan and the 2013 Plan that are forfeited, canceled or otherwise terminated, other than by exercise, will be added back to the shares of Class A common stock available for issuance under the 2019 Plan. Shares tendered F-28 or held back upon exercise of a stock option or settlement of an award under the 2019 Plan or the 2013 Plan 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 Class A common stock available for issuance under the 2019 Plan. In addition, shares of Class A common stock repurchased on the open market will not be added back to the shares of Class A common stock available for issuance under the 2019 Plan. Long-term incentive plan ("LTIP") units are a special class of partnership interests in the Operating Partnership. Each LTIP unit awarded will be deemed equivalent to an award of one share of 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, the Operating Partnership will revalue for tax purposes its assets upon the occurrence of certain specified events, and any increase in valuation from the time of grant until 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 OP unitholders. Subject to any agreed upon exceptions, once vested and having achieved parity with OP unitholders, LTIP units are convertible into OP Units in the Operating Partnership on a one-for-one basis. LTIP units subject to time based vesting, whether vested or not, receive the same per unit distributions as OP Units, which equal per share dividends (both regular and special) on our common stock. Performance based LTIP units 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. The following is net income attributable to common stockholders and the issuance of our class A shares in exchange for the conversion of OP Units into common stock (amounts in thousands): Net income attributable to common stockholders Increase in additional paid-in capital for the conversion of OP Units into common stock Change from net income attributable to common stockholders and transfers from noncontrolling interests Year ended December 31, 2020 2019 2018 $ (16,712) $ 49,445 $ 65,603 30,170 27,740 70,452 $ 13,458 $ 77,185 $ 136,055 As of December 31, 2020, there were approximately 285.3 million common stock and OP Units outstanding, of which approximately 171.6 million, or 60.1%, were owned by us and approximately 113.7 million, or 39.9%, were owned by other partners, including certain directors, officers and other members of executive management. Stock and Publicly Traded Operating Partnership Unit Repurchase Program On December 31, 2019 our board authorized the repurchase of up to $500 million of our Class A common stock and the Operating Partnership’s Series ES, Series 250 and Series 60 operating partnership units from January 1, 2020 through December 31, 2020. On December 11, 2020, our board approved a new authorization for the repurchase of up to $500 million of such securities from January 1, 2021 through December 31, 2021. Under the repurchase 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 and general market conditions. 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. The following table summarizes our purchases of equity securities for the year ended December 31, 2020: Period Total Number of Shares Purchased Average Price Paid Per Share Total Number of Shares Purchased as Part of Publicly Announced Plan Maximum Approximate Dollar Value Available for Future Purchase (in thousands) Year ended December 31, 2020 17,279,252 $ 8.32 17,279,252 $ 356,287 F-29 Private Perpetual Preferred Units As of December 31, 2020, 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"). 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 2019 Preferred Units are not redeemable at the option of the holders and are redeemable at our option only in the case of specific defined events. 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. The Series 2014 Preferred Units are not redeemable at the option of the holders and are redeemable at our option only in the case of specific defined events. Dividends and Distributions The following table summarizes the dividends paid on our Class A common stock and Class B common stock for the years ended December 31, 2020, 2019 and 2018: Record Date Payment Date June 19, 2020 March 16, 2020 December 23, 2019 September 16, 2019 June 14, 2019 March 15, 2019 December 17, 2018 September 14, 2018 June 15, 2018 March 15, 2018 June 30, 2020 March 31, 2020 December 31, 2019 September 30, 2019 June 28, 2019 March 29, 2019 December 31, 2018 September 28, 2018 June 29, 2018 March 30, 2018 Amount per Share $0.105 $0.105 $0.105 $0.105 $0.105 $0.105 $0.105 $0.105 $0.105 $0.105 We paid a dividend in the first and second quarters of 2020 and suspended the dividend for the third and fourth quarters of 2020. Total dividends paid to common securityholders during 2020, 2019 and 2018 were $37.2 million, $75.2 million and $70.9 million, respectively. Total distributions paid to OP unitholders, excluding inter-company distributions, during 2020, 2019 and 2018 totaled $23.7 million, $50.8 million and $54.7 million, respectively. Total distributions paid to Preferred unitholders during 2020, 2019 and 2018 were $4.2 million, $1.7 million, and $0.9 million, respectively. Earnings and profits, which determine the tax treatment of distributions to securityholders, will differ from income reported for financial reporting purposes due to the differences for federal income tax purposes, including, but not limited to, treatment of revenue recognition, compensation expense, and basis of depreciable assets and estimated useful lives used to compute depreciation. The 2020 dividends of $0.21 per share are classified for income tax purposes 100% as taxable ordinary dividends eligible for the Section 199A deduction and 0% as a return of capital. The 2019 dividends of $0.42 per share are classified for income tax purposes 31.4% as taxable ordinary dividends eligible for the Section 199A deduction and 68.6% as a return of capital. The 2018 dividends of $0.42 per share are classified for income tax purposes 83.8% as taxable ordinary dividends eligible for the Section 199A deduction and 16.2% as a return of capital. Incentive and Share-Based Compensation The Plans provide for grants to directors, employees and consultants consisting of stock options, restricted stock, dividend equivalents, stock payments, performance shares, LTIP units, stock appreciation rights and other incentive awards.. An aggregate of 11.0 million shares of our common stock are authorized for issuance under awards granted pursuant to the 2019 Plan, and as of December 31, 2020, approximately 8.5 million shares of common stock remain available for future issuance under the Plans. F-30 In December and August 2020, we granted Grant H. Hill and R. Paige Hood, respectively, our new non-employee directors, a total of 31,117 LTIP units that are subject to time-based vesting with a fair market value of $0.2 million. These awards vest ratably on each of the first three anniversaries of May 15, 2020, subject generally to their continued service on our Board of Directors. In May 2020, we made grants of LTIP units under the 2019 Plan. At such time, we granted our non-employee directors a total of 171,153 LTIP units that are subject to time-based vesting with fair market values of $1.1 million. These awards vest ratably over three years from the date of the grant, subject generally to the director's continued service on our Board of Directors. We also granted Christina Chiu, our Executive Vice President and Chief Financial Officer, a total of 82,199 LTIP units that are subject to time-based vesting and 116,927 LTIP units that are subject to market-based vesting, with fair market values of $0.5 million for the time-based vesting awards and $0.5 million for the market-based vesting awards. We also granted certain other employees a total of 63,229 LTIP units that are subject to time-based vesting with a fair market value of $0.4 million. The awards subject to time-based vesting vest ratably over three or four years from the date of grant, subject generally to the grantee's continued employment. The first installment vests on the respective grant dates in May 2021 and the remainder will vest thereafter in two or three equal annual installments. The vesting of the LTIP units subject to market-based vesting is based on the achievement of relative total stockholder return hurdles over a three-year performance period, commencing on May 7, 2020. Following the completion of the three-year performance period, our Compensation and Human Capital Committee will determine the number of LTIP units to which the grantee is entitled based on our performance relative to the performance hurdles set forth in the LTIP unit award agreements the grantee entered into in connection with the award grant. These units then vest in two installments, with the first installment vesting on May 7, 2023 and the second installment vesting on May 7, 2024, subject generally to the grantee's continued employment on those dates. In March 2020, we made grants of LTIP units to executive officers under the 2019 Plan. At such time, we granted to executive officers a total of 745,155 LTIP units that are subject to time-based vesting and 3,358,767 LTIP units that are subject to market-based vesting, with fair market values of $5.6 million for the time-based vesting awards and $14.0 million for the 22 market-based vesting awards. In March 2020, we made grants of LTIP units and restricted stock to certain other employees under the 2019 Plan. At such time, we granted to certain other employees a total of 113,971 LTIP units and 158,806 shares of restricted stock that are subject to time-based vesting and 502,475 LTIP units that are subject to market-based vesting, with fair market values of $2.3 million for the time-based vesting awards and $2.3 million for the market-based vesting awards. The awards subject to time-based vesting vest ratably over four years from January 1, 2020, subject generally to the grantee's continued employment. The first installment vests on January 1, 2021 and the remainder will vest thereafter in three equal annual installments. The vesting of the LTIP units subject to market-based vesting is based on the achievement of relative total stockholder return hurdles over a three-year performance period, commencing on January 1, 2020. Following the completion of the three-year performance period, our Compensation and Human Capital Committee will determine the number of LTIP units to which the grantee is entitled based on our performance relative to the performance hurdles set forth in the LTIP unit award agreements the grantee entered into in connection with the award grant. These units then vest in two installments, with the first installment vesting on January 1, 2023 and the second installment vesting on January 1, 2024, subject generally to the grantee's continued employment on those dates. For awards granted in 2017, 2018, 2019 and 2020, our named executive officers could elect to receive their annual incentive bonus in any combination of (i) cash or vested LTIP's at the face amount of such bonus or (ii) time-vesting LTIP's which would vest over three years, subject to continued employment, at 125% of such face amount (the "bonus election program"). In March 2020, we made grants of LTIP units to executive officers under the 2019 Plan in connection with the 2019 bonus election program. We granted to executive officers a total of 624,380 LTIP units that are subject to time-based vesting with a fair market value of $4.4 million. Of these LTIP units, 23,049 LTIP units vested immediately on the grant date and 601,331 LTIP units vest ratably over three years from January 1, 2020, subject generally to the grantee's continued employment. The first installment vests on January 1, 2021 and the remainder will vest thereafter in two equal annual installments. In COVID-19 disrupted markets during the first quarter of 2020, the LTIP units that are subject to market-based vesting were undervalued on initial appraisal, and the resulting number of LTIP units issued in March 2020 was reduced on final appraisal to match the original board-approved dollar value. In June 2020, we reduced the grants of LTIP units that are subject to market-based vesting which were awarded to executive officers and certain other employees by 666,933 LTIP units with fair market values of $2.8 million and 99,630 LTIP units with fair market values of $0.5 million, respectively. In October and May 2019, we made grants of LTIP units to our non-employee directors under the 2019 Plan. At such times, we granted a total of 76,718 LTIP units that are subject to time-based vesting with fair market values of $1.1 million. The awards vest ratably over three years from the date of the grant, subject generally to the director's continued service on our Board of Directors. F-31 In March 2019, we made grants of LTIP units to executive officers under the 2013 Plan. At such time, we granted to executive officers a total of 461,693 LTIP units that are subject to time-based vesting and 1,806,520 LTIP units that are subject to market-based vesting, with fair market values of $6.4 million for the time-based vesting awards and $12.8 million for the market-based vesting awards. In March 2019 we made grants of LTIP units and restricted stock to certain other employees under the 2013 Plan. At such time, we granted to certain other employees a total of 61,432 LTIP units and 69,358 shares of restricted stock that are subject to time-based vesting and 113,383 LTIP units that are subject to market-based vesting, with fair market values of $2.0 million for the time-based vesting awards and $0.9 million for the market-based vesting awards. The awards subject to time-based vesting vest ratably over four years from January 1, 2019, subject generally to the grantee's continued employment. The first installment vests on January 1, 2020 and the remainder will vest thereafter in three equal annual installments. The vesting of the LTIP units subject to market-based vesting is based on the achievement of relative total stockholder return hurdles over a three-year performance period, commencing on January 1, 2019. Following the completion of the three-year performance period, our compensation committee will determine the number of LTIP units to which the grantee is entitled based on our performance relative to the performance hurdles set forth in the LTIP unit award agreements the grantee entered into in connection with the award grant. These units then vest in two installments, with the first installment vesting on January 1, 2022 and the second installment vesting on January 1, 2023, subject generally to the grantee's continued employment on those dates. In March 2019, we made grants of LTIP units to executive officers under the 2013 Plan in connection with the 2018 bonus election program. We granted to executive officers a total of 334,952 LTIP units that are subject to time-based vesting with a fair market value of $4.6 million. Of these LTIP units, 26,056 LTIP units vested immediately on the grant date and 308,896 LTIP units vest ratably over three years from January 1, 2019, subject generally to the grantee's continued employment. The first installment vests on January 1, 2020 and the remainder will vest thereafter in two equal annual installments. 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 or four years, or (ii) the period from the date of grant to the date the employee becomes retirement eligible, which may occur upon grant. Prior to amendment of the 2019 Plan on July 13, 2020, an employee is retirement eligible when the employee attains the (i) age of 60 and (ii) the date on which the employee has first completed ten years of continuous service with us or our affiliates. On July 13, 2020, the board amended the 2019 Plan such that the retirement eligibility age was raised from 60 to 65 starting with grant awards issued after such amendment date, and amended certain grant agreements for equity awards issued in early 2020 such that the new retirement age would apply to such 2020 awards issued prior to July 13, 2020. Share-based compensation for market-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 depending on retirement eligibility. For the market-based LTIP units, the fair value of the awards was estimated using a Monte Carlo Simulation model. 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 a six-year 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-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 that are time-based, we estimate the stock compensation expense based on the fair value of the stock at the grant date. LTIP units and restricted stock issued during the year ended December 31, 2020, 2019 and 2018 were valued at $28.3 million, $27.9 million and $23.6 million, respectively. The weighted-average per unit or share fair value was $5.44, $9.56 and $8.54 for grants issued in 2020, 2019 and 2018, respectively. The per unit or share granted in 2020 was estimated on the respective dates of grant using the following assumptions: an expected life from 2.0 to 5.5 years, a dividend rate of 3.70%, a risk-free interest rate from 0.16% to 0.50%, and an expected price volatility from 19.0% to 26.0%. The per unit or share granted in 2019 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 2.40%, a risk-free interest rate from 2.48% to 2.63%, and an expected price volatility from 17.0% to 22.0%. The per unit or share granted in 2018 was estimated on the respective dates of grant using the following assumptions: an expected life of 2.8 years, a dividend rate of 2.30%, a risk-free interest rate of 2.50% and an expected price volatility of 20.0%. No other stock options, dividend equivalents, or stock appreciation rights were issued or outstanding in 2020, 2019 and 2018. F-32 The following is a summary of restricted stock and LTIP unit activity for the year ended December 31, 2020: Unvested balance at December 31, 2019 Vested Granted Forfeited or unearned Unvested balance at December 31, 2020 Restricted Stock LTIP Units Weighted Average Grant Fair Value 118,918 (58,326) 161,449 (4,341) 217,700 5,986,569 $ (1,052,692) 5,042,810 (2,226,403) 7,750,284 $ 9.73 14.04 5.44 7.55 6.94 The total fair value of LTIP units and restricted stock that vested during 2020, 2019 and 2018 was $15.6 million, $10.1 million and $7.7 million, respectively. The LTIP unit and restricted stock award agreements will immediately vest when a grantee attains the (i) age of 60 or 65, as applicable, and (ii) the date on which the grantee has first completed ten years of continuous service with us or our 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 awards, and accordingly, we recognized $2.6 million, $2.0 million and $1.8 million for the years ended December 31, 2020, 2019 and 2018, respectively. Unrecognized compensation expense was $1.4 million at December 31, 2020, which will be recognized over a weighted average period of 2.1 years. For the remainder of the LTIP unit and restricted stock awards, we recognize noncash compensation expense ratably over the vesting period, and accordingly, we recognized $22.9 million, $18.8 million and $17.0 million in noncash compensation expense for the years ended December 31, 2020, 2019 and 2018, respectively. Unrecognized compensation expense was $26.5 million at December 31, 2020, which will be recognized over a weighted average period of 2.2 years. Earnings Per Share Earnings per share for the years ended December 31, 2020, 2019 and 2018 is computed as follows (amounts in thousands, except per share amounts): Numerator - Basic: Net income (loss) Private perpetual preferred unit distributions Net income attributable to non-controlling interests Earnings allocated to unvested shares Net income (loss) attributable to common stockholders - basic Numerator - Diluted: Net income (loss) Private perpetual preferred unit distributions Earnings allocated to unvested shares For the Year Ended December 31, 2020 2019 2018 $ (22,889) $ 84,290 $ 117,253 (4,197) 10,374 (60) (1,743) (33,102) (45) (936) (50,714) (38) (16,772) $ 49,400 $ 65,565 (22,889) $ 84,290 $ 117,253 (4,197) (60) (1,743) (45) (936) (38) $ $ Net income (loss) attributable to common stockholders - diluted $ (27,146) $ 82,502 $ 116,279 Denominator: Weighted average shares outstanding - basic Operating partnership units Effect of dilutive securities: Stock-based compensation plans Weighted average shares outstanding - diluted 175,169 108,657 11 283,837 178,340 119,458 — 297,798 Earnings per share - basic Earnings per share - diluted $ $ (0.10) $ (0.10) $ 0.28 0.28 $ $ 167,571 129,687 1 297,259 0.39 0.39 F-33 There were 307,536, 416,492, and 485,865 antidilutive shares for the years ended December 31, 2020, 2019 and 2018, respectively. 10. Related Party Transactions Tax Protection Agreements In 2013, we entered into a tax protection agreement with Anthony E. Malkin and Peter L. Malkin that is intended to protect to a limited extent the Malkin Group and an additional third party investor in Metro Center (who was one of the original landowners and was involved in the development of the property) against certain tax consequences arising from a transaction involving one of four properties, which we refer to in this section as the protected assets. First, this agreement provides that our operating partnership will not sell, exchange, transfer or otherwise dispose of such protected assets, or any interest in a protected asset, until (i) October 7, 2025, with respect to one protected asset, First Stamford Place, and (ii) the later of (x) October 7, 2021 and (y) the death of both Peter L. Malkin and Isabel W. Malkin, who are 87 and 84 years old, respectively, for the three other protected assets, Metro Center, 10 Bank Street and 1542 Third Avenue, unless: (1) Anthony E. Malkin consents to the sale, exchange, transfer or other disposition; or our operating partnership delivers to each protected party thereunder a cash payment intended to approximate (2) the tax liability arising from the recognition of the pre-contribution built-in gain resulting from the sale, exchange, transfer or other disposition of such protected asset (with the pre-contribution “built-in gain” being not more than the taxable gain that would have been recognized by such protected party if the protected asset been sold for fair market value in a taxable transaction at the time of the consolidation) plus an additional amount so that, after the payment of all taxes on amounts received pursuant to the agreement (including any tax liability incurred as a result of receiving such payment), the protected party retains an amount equal to such protected party’s total tax liability incurred as a result of the recognition of the pre-contribution built-in gain pursuant to such sale, exchange, transfer or other disposition; or (3) the disposition does not result in a recognition of any built-in gain by the protected party. Second, with respect to the Malkin Group, including Anthony E. Malkin and Peter L. Malkin, and one additional third party investor in Metro Center (who was one of the original landowners and was involved in the development of the property), to protect against gain recognition resulting from a reduction in such continuing investor’s share of the operating partnership liabilities, the agreement provides that during the period from October 7, 2013 until such continuing investor owns less than the aggregate number of operating partnership units and shares of common stock equal to 50% of the aggregate number of such units and shares such investor received in the formation transactions, which we refer to in this section as the tax protection period, our operating partnership will (i) refrain from prepaying any amounts outstanding under any indebtedness secured by the protected assets and (ii) use its commercially reasonable efforts to refinance such indebtedness at or prior to maturity at its current principal amount, or, if our operating partnership is unable to refinance such indebtedness at its current principal amount, at the highest principal amount possible. The agreement also provides that, during the tax protection period, our operating partnership will make available to such continuing investors the opportunity (i) to enter into a “bottom dollar” guarantee of their allocable share of $160.0 million of aggregate indebtedness of our operating partnership meeting certain requirements or (ii) in the event our operating partnership has recourse debt outstanding and such a continuing investor agrees, in lieu of guaranteeing debt pursuant to clause (i) above, to enter into a deficit restoration obligation, in each case, in a manner intended to provide an allocation of operating partnership liabilities to the continuing investor. In the event that a continuing investor guarantees debt of our operating partnership, such continuing investor will be responsible, under certain circumstances, for the repayment of the guaranteed amount to the lender in the event that the lender would otherwise recognize a loss on the loan, such as, for example, if property securing the loan was foreclosed and the value was not sufficient to repay a certain amount of the debt. A deficit restoration obligation is a continuing investor’s obligation, under certain circumstances, to contribute a designated amount of capital to our operating partnership upon our operating partnership’s liquidation in the event that the assets of our operating partnership are insufficient to repay our operating partnership liabilities. Because we expect that our operating partnership will at all times have sufficient liabilities to allow it to meet its obligations to allocate liabilities to its partners that are protected parties under the tax protection agreement, our operating partnership’s indemnification obligation with respect to “certain tax liabilities” would generally arise only in the event that the operating partnership disposes in a taxable transaction of a protected asset within the period specified above in a taxable F-34 transaction. In the event of such a disposition, the amount of our operating partnership’s indemnification obligation would depend on several factors, including the amount of “built-in gain,” if any, recognized and allocated to the indemnified partners with respect to such disposition and the effective tax rate to be applied to such gain at the time of such disposition. The operating partnership agreement requires that allocations with respect to such acquired property be made in a manner consistent with Section 704(c) of the Code. Treasury Regulations issued under Section 704(c) of the Code provide partnerships with a choice of several methods of allocating book-tax differences. Under the tax protection agreement, our operating partnership has agreed to use the “traditional method” for accounting for book-tax differences for the properties acquired by our operating partnership in the consolidation. Under the traditional method, which is the least favorable method from our perspective, the carryover basis of the acquired properties in the hands of our operating partnership (i) may cause us to be allocated lower amounts of depreciation and other deductions for tax purposes than would be allocated to us if all of the acquired properties were to have a tax basis equal to their fair market value at the time of acquisition and (ii) in the event of a sale of such properties, could cause us to be allocated gain in excess of its corresponding economic or book gain (or taxable loss that is less than its economic or book loss), with a corresponding benefit to the partners transferring such properties to our operating partnership for interests in our operating partnership. In 2016, we entered into a tax protection agreement with Q REIT Holding LLC, a Qatar Financial Centre limited liability company and a wholly owned subsidiary of the Qatar Investment Authority, a governmental authority of the State of Qatar ("QREIT", and together with any eligible transferee, "QIA"). Subject to certain minimum thresholds and conditions, we will indemnify QIA for certain applicable U.S. federal and state taxes payable by QIA in connection with dividends paid by us on the QIA shares that are attributable to capital gains from the sale or exchange of any U.S. real property interests. Our obligation to indemnify QIA will terminate one year following the date on which the sum of the QIA shares then owned by QIA falls below 10% of our outstanding common shares. Registration Rights We entered into a registration rights agreement with certain persons receiving shares of our common stock or operating partnership units in the formation transactions, including certain members of our senior management team and our other continuing investors. In connection therewith, we have filed, and are obligated to maintain the effectiveness of, an automatically effective shelf registration statement, along with a prospectus supplement, with respect to, among other things, shares of our Class A common stock that may be issued upon redemption of operating partnership units or issued upon conversion of shares of Class B common stock to continuing investors in the public existing entities. Pursuant to the registration rights agreement, under certain circumstances, we will also be required to undertake an underwritten offering upon the written request of the Malkin Group, which we refer to as the holder, provided (i) the registrable shares to be registered in such offering will have a market value of at least $150.0 million, (ii) we will not be obligated to effect more than two underwritten offerings during any 12-month period; and (iii) the holder will not have the ability to effect more than four underwritten offerings. In addition, if we file a registration statement with respect to an underwritten offering for our own account or on behalf of the holder, the holder will have the right, subject to certain limitations, to register such number of registrable shares held by him, her or it as each such holder requests. With respect to underwritten offerings on behalf of the holder, we will have the right to register such number of primary shares as we request; provided, however, that if cut backs are required by the managing underwriters of such an offering, our primary shares shall be cutback first (but in no event will our shares be cut back to less than $25.0 million). We have also agreed to indemnify the persons receiving rights against specified liabilities, including certain potential liabilities arising under the Securities Act, or to contribute to the payments such persons may be required to make in respect thereof. We have agreed to pay all of the expenses relating to the registration and any underwritten offerings of such securities, including, without limitation, all registration, listing, filing and stock exchange or FINRA fees, all fees and expenses of complying with securities or “blue sky” laws, all printing expenses and all fees and disbursements of counsel and independent public accountants retained by us, but excluding underwriting discounts and commissions, any out-of-pocket expenses (except we will pay any holder’s out-of-pocket fees (including disbursements of such holder’s counsel, accountants and other advisors) up to $25,000 in the aggregate for each underwritten offering and each filing of a resale shelf registration statement or demand registration statement), and any transfer taxes. Employment Agreement and Change in Control Severance Agreements We entered into an employment agreement with Anthony E. Malkin, which provides for salary, bonuses and other benefits, including among other things, severance benefits upon a termination of employment under certain circumstances and the issuance of equity awards. In addition, we entered into change in control severance agreements with Thomas P. Durels, Thomas N. Keltner, Jr. and Christina Chiu. F-35 Indemnification of Our Directors and Officers We entered into indemnification agreements with each of our directors, executive officers, chairman emeritus and certain other parties, providing for the indemnification by us for certain liabilities and expenses incurred as a result of actions brought, or threatened to be brought, against (i) our directors, executive officers and chairman emeritus and (ii) our executive officers, chairman emeritus and certain other parties who are former members, managers, securityholders, directors, limited partners, general partners, officers or controlling persons of our predecessor in such capacities. Excluded Properties and Businesses The Malkin Group, including Anthony E. Malkin, our Chairman and Chief Executive Officer, owns non-controlling interests in, and Anthony E. Malkin and Peter L. Malkin control the general partners or managers of, the entities that own interests in nine multi-family properties and five net leased retail properties, (including one single tenant retail property in Greenwich, Connecticut). The Malkin Group also owns non-controlling interests in one Manhattan office property, two Manhattan retail properties and several retail properties outside of Manhattan, none of which were contributed to us in the formation transactions. We refer to the non-controlling interests described above collectively as the excluded properties. In addition, the Malkin Group owns interests in one mezzanine and senior equity fund and five property managers, and which we refer to collectively as the excluded businesses. Other than the Greenwich retail property, we do not believe that the excluded properties or the excluded businesses are consistent with our portfolio geographic or property type composition, management or strategic direction. Pursuant to management and/or service agreements with the owners of interests in those excluded properties and services agreements with five residential property managers and the managers of certain other excluded businesses which historically were managed by affiliates of our predecessor, we are designated as the asset manager (supervisor) and/or property manager of the excluded properties and will provide services to the owners of certain of the excluded properties and the five residential property managers and provide services and access to office space to the existing managers of the other excluded businesses. As the manager or service provider, we are paid a management or other fee with respect to those excluded properties and excluded businesses where our predecessor had previously received a management fee on the same terms as the fee paid to our predecessor, and reimbursed for our costs in providing the management and other services to those excluded properties and businesses where our predecessor had not previously received a management fee. Our management of the excluded properties and provision of services to the five residential property managers and the existing managers of the other excluded businesses represent a minimal portion of our overall business. There is no established time period in which we will manage such properties or provide services to the owners of certain of the excluded properties and the five residential property managers and provide services and access to office space to the existing managers of the other excluded businesses; and Peter L. Malkin and Anthony E. Malkin expect to sell certain properties or unwind these businesses over time. We are not precluded from acquiring all or certain interests in the excluded properties or businesses. If we were to attempt any such acquisition, we anticipate that Anthony E. Malkin, our Chairman and Chief Executive Officer, will not participate in the negotiation process on our behalf with respect to our potential acquisition of any of these excluded properties or businesses, and the approval of a majority of our independent directors will be required to approve any such acquisition. Services are and were provided by us to excluded properties and businesses. These transactions are reflected in our consolidated statements of operations as third-party management and other fees. We earned asset management (supervisory) and service fees from excluded properties and businesses of $0.9 million, $0.9 million and $1.1 million during the years ended December 31, 2020, 2019 and 2018, respectively. We earned property management fees from excluded properties of $0.3 million, $0.3 million and $0.3 million during the years ended December 31, 2020, 2019 and 2018, respectively. Other We receive rent generally at market rental rate for 5,447 square feet of leased space from entities affiliated with Anthony E. Malkin at one of our properties. Under the lease, the tenant has the right to cancel such lease without special payment on 90 days’ notice. We also have a shared use agreement with such tenant to occupy a portion of the leased premises as the office location for Peter L. Malkin, our chairman emeritus and employee, utilizing approximately 15% of the space, for F-36 which we pay to such tenant an allocable pro rata share of the cost. We also have agreements with these entities and excluded properties and businesses to provide them with general computer-related support services. Total revenue aggregated $0.3 million, $0.3 million and $0.3 million for the years ended December 31, 2020, 2019 and 2018, respectively. 11. Income Taxes TRS Holdings and Observatory TRS are taxable entities and their consolidated provision for income taxes consisted of the following for the years ended December 31, 2020, 2019 and 2018 (amounts in thousands): Current: Federal State and local Total current Deferred: Federal State and local Total deferred For the Year Ended December 31, 2020 2019 2018 $ 4,932 $ (1,077) $ 2,699 7,631 (340) (320) (660) (872) (1,949) (248) (232) (480) (2,389) (2,253) (4,642) — — — Income tax benefit (expense) $ 6,971 $ (2,429) $ (4,642) In December 2017, the Tax Cuts and Jobs Act (the “TCJA”) was enacted. The TCJA includes a number of changes to existing U.S. tax laws, most notably a reduction of the U.S. corporate income tax rate from 35 percent to 21 percent, effective January 1, 2018. In March 2020, the Coronavirus Aid, Relief, Economic Security (“CARES”) Act was enacted. The CARES Act includes a number of federal tax reliefs, including the carryback of a net operating loss (“NOL”) incurred in 2018, 2019 and 2020 to each of the five preceding taxable years to generate a refund of previous paid income taxes. Such NOLs may offset 100% of taxable income for taxable years beginning before 2021 (80% thereafter). Many states, including New York, have not adopted the NOL provisions of the CARES Act and continue to have their own rules with respect to the application of NOLs. The carryback of Observatory TRS’s NOL to previous tax years resulted in a 13% increase of U.S. corporation income tax benefit. As of December 31, 2020, Empire State Realty Trust, Inc. had $67.9 million NOL carryforwards that may be used in the future to reduce the amount otherwise required to be distributed by us to meet REIT requirements. However, for federal income tax purposes, the NOL will not be able to offset more than 80% of our REIT taxable income and, therefore, may not be able to reduce the amount required to be distributed by us to meet REIT requirements to zero, except for the tax year ended December 31, 2020, of which we were able to offset 100% of our REIT taxable income in accordance with the CARES Act. The federal NOL may be carried forward indefinitely. Other limitations may apply to our ability to use our NOL to offset taxable income. As of December 31, 2020, the observatory TRS had a federal, state, and local income tax receivable of $8.1 million due to a NOL for the year ended December 31, 2020. Under special provisions of the CARES Act, the NOL can be carried back five years for federal income tax purposes. Due to limitations on the use of net operating loss carrybacks for state and local tax, the observatory TRS will carry forward $3.8 million of NOL to offset future taxable income, if any. The state and local NOL can be carried forward for up to 20 years. We measure deferred tax assets using enacted tax rates that will apply in the years in which the temporary differences are expected to be recovered or paid. The effective income tax rate is 47.0%, 34.0% and 34.0% for the years ended December 31, 2020, 2019 and 2018, respectively. The actual tax provision differed from that computed at the federal statutory corporate rate as follows (amounts in thousands): F-37 Federal tax benefit (expense) at statutory rate State income tax benefit (expense), net of federal benefit Corporate income tax rate adjustment Income tax benefit (expense) For the Year Ended December 31, 2020 2019 2018 $ $ 2,544 $ (1,575) $ 2,379 2,048 (854) — (2,844) (1,798) — 6,971 $ (2,429) $ (4,642) The income tax effects of temporary differences that give rise to deferred tax assets are presented below as of December 31, 2020, 2019 and 2018 (amounts in thousands): 2020 2019 2018 Deferred tax assets: Deferred revenue on unredeemed observatory admission ticket sales $ New York City net operating loss carryforward credit Deferred tax assets $ 256 $ 334 590 $ 916 $ — 916 $ 1,396 — 1,396 Deferred tax assets at December 31, 2020, 2019 and 2018, respectively, are attributable to the inclusion of deferred revenue on observatory admission ticket sales not redeemed at year-end in determining income for tax reporting purposes and are included in prepaid expenses and other assets on the consolidated balance sheets. The deferred tax assets at December 31, 2020, respectively, are attributable to the inclusion of the New York City net operating loss to be carried forward and utilized during income years for a period of 20 years. No valuation allowance has been recorded against the deferred tax asset because the company believes that the deferred tax asset will, more likely than not, be realized. This determination is based on the observatory TRS’s anticipated future taxable income and the reversal of the deferred tax asset. At December 31, 2020, 2019 and 2018, the TRS entities have no amount of unrecognized tax benefits. For tax years 2020, 2019, 2018 and 2017, the United States federal and state tax returns are open for examination. 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, repositioning and disposition of our 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 different 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 profit for each segment for the years ended December 31, 2020, 2019 and 2018, as reviewed by management (amounts in thousands): F-38 Revenues: Rental revenue Intercompany rental revenue Observatory revenue Lease termination fees Third-party management and other fees Other revenue and fees Total revenues Operating expenses: Property operating expenses Intercompany rent expense Ground rent expense General and administrative expenses Observatory expenses Real estate taxes Impairment charges Depreciation and amortization Total operating expenses Total operating income (loss) Other income (expense): Interest income Interest expense Loss on early extinguishment of debt IPO litigation expense Loss before income taxes Income tax (expense) benefit Net loss Segment assets Expenditures for segment assets 2020 Real Estate Observatory Intersegment Elimination Total $ 563,071 $ 17,827 — 9,416 1,225 6,459 $ — — 29,057 — — — — $ 563,071 (17,827) — — — — — 29,057 9,416 1,225 6,459 597,998 29,057 (17,827) 609,228 136,141 — 9,326 62,244 — 121,923 6,204 190,863 526,701 71,297 2,542 (89,907) (86) (1,165) (17,319) (843) — 17,827 — — 23,723 — — 143 41,693 (12,636) 95 — — — (12,541) 7,814 $ $ $ (18,162) $ (4,727) $ 3,903,884 101,306 $ $ 246,811 2,754 $ $ — 136,141 (17,827) — — — — — — (17,827) — — — — — — — — — — $ $ $ — 9,326 62,244 23,723 121,923 6,204 191,006 550,567 58,661 2,637 (89,907) (86) (1,165) (29,860) 6,971 (22,889) 4,150,695 104,060 F-39 2019 Real Estate Observatory Intersegment Elimination Total — $ 586,414 $ — — 128,769 — — — (82,469) — — — — 128,769 (82,469) — 128,769 4,352 1,254 10,554 731,343 — 82,469 — — 33,767 — 30 116,266 12,503 — — 12,503 (1,533) 10,970 260,623 64,294 $ $ $ — 174,977 (82,469) — — — — — (82,469) — — — — — — — — — 9,326 61,063 33,767 115,916 181,588 576,637 154,706 11,259 (79,246) 86,719 (2,429) 84,290 3,931,834 255,924 $ $ $ Revenues: Rental revenue Intercompany rental revenue Observatory revenue Lease termination fees Third-party management and other fees Other revenue and fees Total revenues Operating expenses: Property operating expenses Intercompany rent expense Ground rent expense General and administrative expenses Observatory expenses Real estate taxes Depreciation and amortization Total operating expenses Total operating income Other income (expense): Interest income Interest expense Income before income taxes Income tax expense Net income Segment assets Expenditures for segment assets $ 586,414 $ 82,469 — 4,352 1,254 10,554 685,043 174,977 — 9,326 61,063 — 115,916 181,558 542,840 142,203 11,259 (79,246) 74,216 (896) 73,320 3,671,211 191,630 $ $ $ $ $ $ F-40 Revenues: Rental revenue Intercompany rental revenue Tenant expense reimbursement Observatory revenue Lease termination fees Third-party management and other fees Other revenue and fees Total revenues Operating expenses: Property operating expenses Intercompany rent expense Ground rent expense General and administrative expenses Observatory expenses Real estate taxes Depreciation and amortization Total operating expenses Total operating income Other income (expense): Interest income Interest expense Income before income taxes Income tax expense Net income Segment assets Expenditures for segment assets 2018 Real Estate Observatory Intersegment Elimination Total $ 493,231 $ 79,954 72,372 — 20,847 1,440 12,394 — — — 131,227 — — — $ — $ 493,231 (79,954) — — — — — — 72,372 131,227 20,847 1,440 12,394 680,238 131,227 (79,954) 731,511 167,379 — 9,326 52,674 — 110,000 168,430 507,809 172,429 10,661 (79,623) 103,467 (1,114) 102,353 3,930,330 201,685 $ $ $ $ $ $ — 79,954 — — 32,767 — 78 112,799 18,428 — — 18,428 (3,528) 14,900 265,450 54,811 $ $ $ — 167,379 (79,954) — — — — — (79,954) — — — — — — — — — 9,326 52,674 32,767 110,000 168,508 540,654 190,857 10,661 (79,623) 121,895 (4,642) 117,253 4,195,780 256,496 $ $ $ During the second quarter 2020, we wrote-off $4.1 million of prior expenditures on a potential energy efficiency project in our real estate segment that is not economically feasible in today's regulatory environment.

For the year ended December 31, 2020, the total $6.2 million write-off is shown as Impairment charges in the consolidated statement of operations. F-41 13.
