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 more than 50% and improving Fifth Avenue access for our office tenants and their visitors.

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.

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 expect to spend approximately $40.0 million through 2020 on our well-maintained and well-located properties’ common areas and amenities to enhance competitiveness and protect our market position.

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.

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.

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.

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 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;

▪ ($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;

▪ 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.

• 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.

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 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.

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.

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.

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

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.

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

The decrease reflects lower management fee income due to fewer assets under management.

Management fee income was consistent with prior year.

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.

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 increase in property operating expenses was primarily due to higher repair and labor costs partially offset by lower utility costs.

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

1 unchanged sentence

General and Administrative Expenses

transition provisions of the standard at adoption.

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.

category, “Rental Revenue,” in the 2019 consolidated statement of income.

The following table reflects the components of

2019 rental revenue:

ESRT's charter and bylaws do not limit the amount or percentage of indebtedness that we may incur nor do they restrict the form in which our indebtedness will be taken (including, but not limited to, recourse or non-recourse debt and cross-collateralized debt).

Our overall leverage depends on our mix of investments and the cost of leverage, however, we maintain a level of indebtedness consistent with our plan to seek an investment grade credit rating.

ESRT's board of directors may from time to time modify our leverage policies in light of the then-current economic conditions, relative costs of debt and equity capital, market values of our properties, general market conditions for debt and equity securities, fluctuations in the market price of ESRT's common stock and our traded OP units, growth and acquisition opportunities and other factors.

Comparison of Year Ended December 31, 2020 to the Year Ended December 31, 2019

Cash and cash equivalents and restricted cash were $567.9 million and $271.6 million as of December 31, 2020 and 2019, 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.

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 $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.

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 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.

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 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 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

Cash and cash equivalents and restricted cash were $271.6 million and $270.8 million as of December 31, 2019 and 2018, respectively.

The decrease was primarily due to investments in short-term time deposits and capital

improvements and expenditures offset by net proceeds from the issuance of debt during the year ended December 31, 2018.

Operating activities .

Net cash provided by operating activities increased by $84.8 million to $279.0 million for the year ended December 31, 2018 compared to $194.2 million for the year ended December 31, 2017 mainly attributable to payments of operating liabilities that occurred in 2017 which were absent in 2018.

2017 included a payment of an amount owed to the estate of Leona M.

Helmsley, as required under our formation agreements, equal to the New York City transfer taxes which would have been payable by us in absence of the estate's exemption from such tax.

This amount had been accrued as a liability at our formation in October 2013 and became payable upon the taxing authority's final approval of such exemption in September 2017, so the reduction in our liabilities matched the reduction in our cash.

Investing activities .

Net cash used in investing activities increased by $420.0 million to $643.0 million for the year ended December 31, 2018 compared to $223.0 million for the year ended December 31, 2017 due to investments in short-term time deposits made during 2018.

Depreciation and amortization expenses as well as gains or losses from the sale of operating real estate assets are eliminated because they may not accurately represent the actual change in value in our office or retail properties that result from use of the properties or changes in market conditions.

While certain aspects of real property do decline in value over time in a manner that is reasonably captured by depreciation and amortization, the value of the properties as a whole have historically increased or decreased as a result of changes in overall economic conditions

instead of from actual use of the property or the passage of time.

Gains and losses from the sale of real property vary from property to property and are affected by market conditions at the time of sale which will usually change from period to period.

1 unchanged sentence

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 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.

Observatory and Broadcasting Operations

For the year ended December 31, 2019 , the Empire State Building Observatory hosted 3,505,000 visitors, compared to 3,805,000 visitors for the same period in 2018 , a decrease of 7.9% .

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 the closure of the 102nd floor observation deck as part of the Observatory upgrade program and a visitation decline, partially offset by improved pricing.

In the year ended December 31, 2019 , there were 73 bad weather days, compared to 56 bad weather days in the year ended December 31, 2018 .

The elevator servicing the 102nd floor Observatory was closed to visitors during the first quarter of 2018 for the planned replacement of the original machinery and a new, higher speed glass elevator.

The 102nd floor Observatory was closed for approximately nine months in 2019 and opened on October 12, 2019.

The work on the 80th floor component of our Observatory upgrade program has also been completed and the 80th floor opened in November 2019.

We performed an annual review of goodwill for impairment and concluded there was no impairment of goodwill.

Our methodology to review goodwill impairment, which includes a significant amount of judgment and estimates, provides a reasonable basis to determine whether impairment has occurred.

However, 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.

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.

As of December 31, 2020, our parent and general partner, 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 ESRT to meet REIT requirements.

However, for federal income tax purposes, the NOL will not be able to offset more than 80% of ESRT’s REIT taxable income and, therefore, may not be able to reduce the amount required to be distributed by ESRT to meet REIT requirements to zero, except for the tax year ended December 31, 2020, of which ESRT was able to offset 100% of its 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 ESRT’s ability to use its NOL to offset taxable income.
