Equity Commonwealth
Annual Report 2023

Plain-text annual report

2023 Annual Report Dear Fellow Shareholders: As we approach the tenth anniversary of our stewardship of Equity Commonwealth, there is much we have accomplished. Since taking responsibility for the company in 2014, the EQC team has remained focused in its efforts and executed a disciplined strategy. We have: • Completed $7.6 billion of dispositions, including the sale of 164 office properties totaling 44 million square feet and three land parcels, • Distributed $1.8 billion, or $14.75 per Common Share, to our common shareholders, • Repurchased $652 million of our Common Shares at a weighted average, dividend adjusted price of $17.63 per share, • Repaid debt and preferred equity of $3.3 billion, and • Generated a cash balance of $2.2 billion, or $19.95 per share. Throughout this time, one of our guiding principles has been to be responsive to evolving market conditions. For the first six years, following this principle was relatively straightforward – valuations were at or near all-time highs, and we concluded that it was in shareholders’ best interests to sell assets. We sold $7.6 billion of assets between 2015 and early 2020. When the Covid-19 pandemic hit, office values plummeted. At the same time, we evaluated numerous investment opportunities, seeking to acquire a business with strong fundamentals and a compelling risk-reward profile that would create long-term value for our shareholders. To date, we have not found such an opportunity. In 2023, our Chairman, Sam Zell, passed away. He was a visionary who is widely recognized as the founder of the modern REIT industry. Under his leadership, we transitioned EQC from external to internal management, brought on a new board and management team, and replaced the company’s corporate governance and executive compensation program to align them with industry best practices. Sam fostered a unique culture that serves as the foundation of EQC, and the principles he inculcated continue to guide us. Today, we are continuing our efforts to maximize shareholder value. We remain focused on opportunities in our pipeline where we can create long-term value for our shareholders, while concurrently taking steps to facilitate the potential wind down of our business. Before the end of this year, we expect to either announce a transaction or move forward with a plan to wind down our business. Looking ahead, we will continue to communicate openly with our shareholders. Since taking control of EQC in 2014, the Board and management team have demonstrated that creating long-term value is our priority. This commitment has not changed, and we will continue to be responsible stewards of our investors’ capital. I want to thank the team at EQC for your steadfast commitment and dedication. To our fellow shareholders, thank you for your continued support.

EXPLANATORY NOTE Item 1. Business. PART I The Company. We are an internally managed and self-advised real estate investment trust, or REIT, primarily engaged in the ownership and operation of office buildings in the United States. We were formed in 1986 under Maryland law and we have elected to be taxed as a REIT under the Internal Revenue Code of 1986, as amended, or the Code. The Company operates as what is commonly referred to as an umbrella partnership real estate investment trust, or UPREIT, conducting substantially all of its activities through EQC Operating Trust, a Maryland real estate investment trust, or the Operating Trust. The Company beneficially owned 99.79% of the outstanding shares of beneficial interest, designated as units, or OP Units, in the Operating Trust, as of December 31, 2023, and the Company is the sole trustee of the Operating Trust. As the sole trustee, the Company generally has the power under the declaration of trust of the Operating Trust to manage and conduct the business of the Operating Trust, subject to certain limited approval and voting rights of other holders of OP Units. As of December 31, 2023, our portfolio consisted of four properties, with a total of 1.5 million square feet. Over the past ten years, we disposed of 164 properties and three land parcels totaling 44.3 million square feet for an aggregate gross sales price of $6.9 billion, as well as $704.8 million of common shares of Select Income REIT. The remaining four properties were 81.2% leased and had 80.0% commenced occupancy as of December 31, 2023. Since 2014, we have used proceeds to retire $3.3 billion of debt and preferred shares, repurchased $652.1 million of our common shares and paid $1.8 billion in distributions to our common shareholders. We have $2.2 billion of cash and cash equivalents and no debt outstanding as of December 31, 2023. Our business has been and is continuing to be impacted by economic uncertainty and an overall slowdown in the office leasing market following the COVID-19 pandemic due to a variety of factors, including tenant uncertainty regarding office space needs given the evolving remote and hybrid working trends and other factors impacting the demand for office space. The Company has experienced a significant reduction in leasing interest and activity as well as parking revenue when compared to pre-pandemic levels. Many of our employees and the vast majority of our tenants' employees are currently working at least in part remotely, with many businesses reassessing their long-term demand for office space. The duration of these business disruptions continues to be unknown at this time, and we currently are not able to estimate the full impact of the overall slowdown in the office leasing market on our business. During the year ended December 31, 2023, we entered into leases for 214,000 square feet, including lease renewals for 157,000 square feet and new leases for 57,000 square feet. Leases entered into during the year ended December 31, 2023, including both lease renewals and new leases, had weighted average cash rental rates that were approximately 1.6% higher than prior rental rates for the same space and weighted average GAAP rental rates that were approximately 13.7% higher than prior rental rates for the same space. As of December 31, 2023, approximately 17.1% of our leased square feet and 15.7% of our annualized rental revenue are included in leases scheduled to expire through December 31, 2024. Renewal and new leases and rental rates at which available space may be relet in the future will depend on prevailing market conditions at the times these leases are negotiated. We believe that the in-place cash rents for leases expiring in 2024, that have not been backfilled, are approximately market, and we also expect most of the tenants with leases expiring in 2024 to vacate. Business Strategy. We are continuing to evaluate investment opportunities while remaining focused on creating value through proactive asset management and improved operating results. We are seeking to use the strength and liquidity of our balance sheet for investments in high-quality assets or businesses in a broad range of property types that offer a compelling risk-reward profile. We intend to be patient and disciplined in our evaluation of investment opportunities while remaining focused on proactive asset management, leasing and operations at our four remaining properties, some or all of which we may sell to the extent we determine that is in the best interests of our business objectives. We may also determine to sell, liquidate or otherwise exit our business if we believe doing so will maximize shareholder value. Human Capital Resources. As of December 31, 2023, we had 22 full-time employees, reduced from 66 full-time employees as of December 31, 2015, as the size of our property portfolio decreased. Our employee compensation program consists of the following: (i) base salary, (ii) annual cash bonus, (iii) long-term, at-risk time and performance-based equity awards, and (iv) health and welfare benefits. Each year, we set corporate, department and individual goals that we use to measure performance during our annual review process. We believe that the structure of our compensation program is aligned 1 with the interests of our shareholders, rewards performance and serves to attract and retain employees. We also believe that our entrepreneurial culture, which is focused on encouraging transparency and open communication based on our guiding principles, is an important contributor to our success. We strive to provide our employees with a variety of resources and tools to promote training and development. For more information on our human capital resources, please see the section below on Social Responsibility. Our principal executive offices are located at Two North Riverside Plaza, Suite 2000, Chicago, Illinois 60606, our telephone number is (312) 646-2800 and our website is www.eqcre.com. Investment Policies. In evaluating potential property investments and dispositions, we consider various factors, including but not limited to the following: • • • • • • • • • • the type of properties; the risk-adjusted returns projected for the properties; the historical and projected rents received and likely to be received from the properties; the historical and expected operating expenses, including real estate taxes, incurred and expected to be incurred at the properties; the growth, tax and regulatory environments of the market in which the properties are located; the quality and credit worthiness of the tenants; occupancy and demand for similar properties in the same or nearby markets; the construction quality, physical condition, environmental risk-factors and design of the properties, and expected capital expenditures that may need to be made; the location of the properties; and the pricing of comparable properties as evidenced by recent market sales. We have no policies that specifically limit the percentage of our assets that may be invested in any individual property, in any one type of property, in properties in one geographic area, in properties leased to any one tenant, in properties leased to an affiliated group of tenants, in real estate joint ventures or in participating, convertible or other types of mortgages. We have in the past provided seller financing for properties we have sold and may do so again in the future. In the past, we have sought to acquire and considered the possibility of acquiring other companies, including via merger or other strategic combinations. We may undertake such activities in the future. Financing Policies. We may seek additional capital through equity offerings, debt financings, retention of cash flows in excess of distributions to shareholders or a combination of these methods. To the extent that our Board of Trustees decides to obtain debt financing, we may do so on an unsecured basis or a secured basis, subject to limitations in any then-existing financing or other contractual arrangements; we may seek to obtain lines of credit or to issue securities senior to our common and/or preferred shares, including preferred shares or debt securities which may be convertible into common shares or be accompanied by warrants to purchase common shares; or we may engage in transactions which involve a sale or other conveyance of properties to affiliated or unaffiliated entities. We may finance investments by using retained cash flow from operations and dispositions, by the issuance of additional equity securities or debt, by assuming outstanding mortgage debt on the acquired properties or by an exchange of properties. The proceeds from any of our financings may be used to pay distributions, to provide working capital, to refinance indebtedness or to finance investments and expansions of existing or new properties or businesses. We may from time to time re-evaluate and modify our financing policies in light of then current market conditions, relative availability and costs of debt and equity capital, the changing values of properties, growth and investment opportunities and other factors, and we may increase or decrease our ratio of debt to total capitalization. The Investment Policies and Financing Policies discussed above are established by our Board of Trustees and may be changed by our Board of Trustees at any time without shareholder approval. Competition. Investing in and operating real estate is a highly competitive business. We compete against other REITs, numerous financial institutions, individuals and public and private companies who are actively engaged in the real estate business. Also, we compete for tenants and investments based on a number of factors including pricing, building quality and location, underwriting criteria and reputation. Our ability to successfully compete is also impacted by economic and population trends, availability of acceptable investment opportunities, our ability to negotiate beneficial leasing and investment terms, availability and cost of capital and new and existing laws and regulations. Some of our competitors are dominant in selected 2 geographic markets, including in markets in which we operate. Some of our competitors have greater financial and other resources than we have. For additional information on competition and the risks associated with our business, please see “Risk Factors” in Part I, Item 1A of this Annual Report on Form 10-K. Corporate Responsibility. Our Company believes that sustainability, social responsibility and strong corporate governance (collectively, “Corporate Responsibility”) are key contributors to our success. Our approach to Corporate Responsibility matters is all-inclusive, addressing our effect on the environment, our social impact and our relationships with all of our stakeholders, including our shareholders, tenants, employees and vendors. Our commitment to the principles of sustainability starts at the top: our Board oversees our sustainability program and initiatives, our management team regularly reports to our Board on that program and our executive officers are evaluated and compensated, in part, on the Company’s efforts with respect to Corporate Responsibility initiatives. Our CEO directly oversees our sustainability activities and performance, and our CEO and General Counsel, along with senior members of our sustainability team, regularly update our Board on sustainability initiatives. We have a sustainability team focused on sustainability risks and initiatives, whose team co-managers report directly to our CEO and General Counsel. This team is co-managed by our Senior Vice President of Engineering, Construction and Operations and our Senior Vice President – Legal. The team comprises and leverages a variety of subject matter experts within the Company (e.g., human resources, engineering, information technology, leasing, legal, asset management and finance) as well as a variety of third-party consultants. The Company is a member of GRESB, a globally recognized independent organization that provides validated Corporate Responsibility performance data and peer benchmarks of more than 1,500 real estate portfolios worldwide. GRESB is also aligned with many of the standards set forth in the Task Force on Climate-Related Financial Disclosures (“TCFD”). Our annual GRESB assessment rating improved by 8 points to achieve an overall score of 80 in 2023. The following summary describes some of our Corporate Responsibility principles and achievements in further detail. For a more thorough description of the Company’s Corporate Responsibility initiatives and goals, please see the Company’s 2023 Corporate Responsibility Report in the investor relations “Corporate Responsibility” portion of the Company’s website at www.eqcre.com. This report, which was published following the review and approval of our Board of Trustees, includes a third-party assurance statement and incorporates certain TCFD recommendations related to climate resilience strategy, transition and physical climate risks and climate opportunities. The 2023 Corporate Responsibility Report is not part of or incorporated into this Annual Report on Form 10-K. Corporate Governance We are committed to a corporate governance approach that promotes transparency as well as alignment with and accountability to our shareholders. We regularly look to improve our corporate governance policies and practices, which include: 3 ✔ Majority voting in uncontested trustee elections ✔ Annual trustee elections, with shareholder approval required to stagger the Board ✔ Lead independent trustee with robust duties ✔ 6 of 7 trustees are independent ✔ Regular executive sessions of independent trustees ✔ All members of Audit Committee, Compensation Committee and Nominating and Corporate Governance Committee are independent ✔ All members of Audit Committee are financially literate with two of three being audit committee financial experts under SEC rules ✔ Annual board and committee review and self-evaluations ✔ Code of Business Conduct and Ethics that covers trustees and employees as well as the Company’s relationships with its vendors ✔ Meaningful share ownership guidelines for our trustees (4x annual cash retainer), chief executive officer (6x salary) and other named executive officers (3x salary) ✔ Opted out of Maryland business combination and control share acquisition statutes ✔ No shareholder rights plan (commonly known as a “poison pill”) ✔ Active shareholder engagement ✔ Shareholders have ability to amend the Company’s bylaws by majority vote Our Board reviews our corporate governance practices regularly, and we strive to operate the Company on a foundation of strong corporate governance principles. For further information on our corporate governance structure and policies, please see “Directors, Executive Officers and Corporate Governance” in Item 10 of Part III of this Annual Report on Form 10-K. Environmental The Company’s sustainability approach seeks to actively manage environmental impacts and climate-related risks and opportunities. Our environmental and climate strategic planning and initiatives, combined with our targeted capital investments, are aimed at reducing carbon emissions, mitigating risks and potentially realizing climate-related opportunities that benefit our stakeholders. Our 2023 accomplishments with respect to environmental initiatives include the following: ● ● created a stand-alone 2023 Corporate Responsibility Report, detailing the Company’s sustainability goals, initiatives and achievements; obtained an Independent Assurance Statement for Scope 2 greenhouse gas (“GHG”) emissions and consumption data at our portfolio properties for calendar year 2022. This assurance audit was performed to a limited level of assurance and materiality based on the verifier’s professional judgment, using the independent third party’s verification procedure and ISAE 3000 for GHG emissions. A copy of the Independent Assurance Statement is attached to the Company’s 2023 Corporate Responsibility Report, available on our website at www.eqcre.com; ● maintained LEED certification for 50% of our portfolio properties; ● ● ● completed a climate-related risk assessment, in line with certain recommendations made by TCFD, with respect to our properties and corporate headquarters; this assessment and other disclosures are available in the Company’s 2023 Corporate Responsibility Report, accessible through our website at www.eqcre.com; invested in energy efficiency projects by upgrading older, pneumatic Variable Air Volume (“VAV”) boxes to direct digital control and connecting them to existing Building Automation Systems as part of ongoing tenant improvements at our portfolio properties; and enhanced our portfolio leases by incorporating additional energy conservation, energy consumption data sharing and sustainability-related clauses in new tenant leases as well as lease amendments with existing tenants. As an owner of real estate, we are subject to various federal, state and local laws and regulations relating to environmental, health and safety matters, including those relating to the presence of hazardous substances. We estimate the cost to remove hazardous substances or address environmental issues (including the presence of asbestos-containing materials) at some of our properties based in part on environmental surveys and analyses conducted on our properties. We do not believe that 4 there are environmental conditions or issues at any of our properties that have had or will have a material adverse effect on us. However, no assurances can be given that conditions or issues are not present at our properties or that costs we may be required to incur in the future to remediate contamination or comply with environmental, health and safety laws will not have a material adverse effect on our business or financial condition. The federal government and some of the states and localities in which our properties are located have enacted and may in the future enact climate change laws and regulations. We believe these laws may cause energy costs at our properties to increase, but we do not expect the direct impact of these increases to be material to our results of operations because the increased costs either would be the responsibility of our tenants directly or in large part may be passed through by us to our tenants as additional lease payments. While we evaluate ways to improve the energy efficiency at our properties, laws enacted to mitigate climate change may cause us to make material investments in our properties which could materially and adversely affect our financial condition. For more information regarding environmental matters and their possible adverse impact on us, including climate change matters, see “Risk Factors—Risks Related to Our Business—Any environmental contamination or other environmental liabilities could materially and adversely affect us” and “Risk Factors—Risks Related to Our Business—We may be adversely affected by laws, regulations or other issues related to climate change, including the physical impacts of climate change on our properties” both in Part I, Item 1A of this Annual Report on Form 10-K. Social Responsibility We believe in a shared commitment to diversity, ethics, integrity and community engagement, which commitment serves as the foundation of our corporate purpose. Diversity of all types brings varying perspectives, encouraging differing viewpoints in order to effectively manage risk and create value. We have continued to focus our efforts in the areas of diversity and inclusion (“D&I”), as well as employee health and wellness. Our President and CEO David Helfand signed the CEO Action for Diversity & Inclusion Pledge as a signal that we will put D&I into action by creating a culture of involvement, respect and connection, where all employees’ voices are heard. Our goal is to create and sustain an inclusive environment where diversity thrives and employees want to work. Our vision of diversity includes race, gender, age, sexual orientation, physical ability and ethnicity, among others, and celebrating diversity is one of our core values. The Company acknowledges that improving D&I in our business will require a long-term, sustained effort. Toward that end, we launched an online weekly microlearning platform focused on diversity, inclusion and leadership development, surveyed vendors regarding the diversity of their team members and enhanced our parental leave policy to provide paid time off for primary and secondary caregivers. We also conducted stakeholder engagement surveys for both our employees and our portfolio tenants. In our October 2022 employee survey, we had a 91% overall response rate, with 85% of the participants reporting they are “very happy” to be working at EQC. Additionally, 85% praised EQC’s open and honest two-way communication and 80% of the participants indicated that their perspective and opinions are heard and valued. Overall, the survey provided meaningful feedback and an opportunity to discuss and address employee concerns. These surveys form an important part of our ongoing focus on engagement and overall employee experience. Our commitment to community brings active engagement, both as individuals and in our corporate capacity. Over the years, we have been actively involved with and supported local organizations and community outreach programs, including the Greater Chicago Food Depository and other Chicago-based, grass-roots organizations, by coordinating group events and encouraging employees to dedicate time volunteering to make positive impacts in their communities. Further details of community engagement are available in our 2023 Corporate Responsibility Report at www.eqcre.com. We seek to maintain the highest standards of integrity and ethics. We have implemented a set of rules that governs our conduct and can be found in our Code of Business Conduct and Ethics, which covers our employees and trustees and applies to the Company’s relationships with its vendors. This Code remains a cornerstone in fostering a respectful and ethical work experience at the Company, setting forth our anti-bribery policy, our standards with respect to compliance with the United States Foreign Corrupt Practices Act and similar governance-related matters. For further information on our efforts with respect to Corporate Responsibility, please visit our Corporate Responsibility page in the investor relations section of our website at www.eqcre.com. Taxation as a REIT. The Company has elected to be taxed as a REIT under the Code. A REIT generally is not subject to U.S. federal income tax on the net income that it distributes to shareholders if it meets the applicable REIT distribution 5 requirements and other requirements for REIT qualification under the Code. We believe that we have been organized and have operated so as to qualify as a REIT, but there can be no assurance that we qualify or will remain qualified as a REIT. The law firm of Fried, Frank, Harris, Shriver & Jacobson LLP (“Fried Frank”) has acted as our tax counsel in connection with the filing of this annual report. We have received an opinion from Fried Frank, dated February 13, 2024, that we have been organized and have operated in conformity with the requirements for qualification and taxation as a REIT under the Code for each of our taxable years beginning with our taxable year ended December 31, 2020 through our taxable year ended December 31, 2023. It must be emphasized that the opinion of Fried Frank is based on various assumptions relating to our organization and operation, is conditioned upon factual representations and covenants made by our management regarding our organization, assets, income, the conduct of our business operations, the economic terms of our leases, and other items regarding our ability to meet the various requirements for qualification as a REIT, the results of which have not been and will not be reviewed by Fried Frank, and assumes that such representations and covenants are accurate and complete and that we have taken no action inconsistent with our qualification as a REIT. Given the highly complex nature of the rules governing REITs, the ongoing importance of factual determinations, and the possibility of future changes in our circumstances, no assurance can be given by Fried Frank or by us that we will qualify as a REIT for any particular year. The opinion of Fried Frank was expressed as of the date issued. Fried Frank will have no obligation to advise us or our shareholders of any subsequent change in the matters stated, represented or assumed, or of any subsequent change in the applicable law. You should be aware that opinions of counsel are not binding on the IRS, and no assurance can be given that the IRS will not challenge the conclusions set forth in such opinions. Fried Frank’s opinion does not foreclose the possibility that we may have to utilize one or more of the REIT savings provisions, which could require us to pay an excise or penalty tax (which tax could be significant in amount) in order for us to maintain our REIT qualification. Qualification and taxation as a REIT depend upon our ability to meet, through actual annual (or in some cases quarterly) operating results, requirements relating to income, asset ownership, distribution levels and diversity of share ownership, and the various other REIT qualification requirements imposed under the Code. Given the complex nature of the REIT qualification requirements, the ongoing importance of factual determinations and the possibility of future changes in our circumstances, we cannot provide any assurance that our actual operating results will satisfy the requirements for taxation as a REIT under the Code for any particular taxable year. Regulation FD Disclosures and Internet Website. We use any of the following to comply with our disclosure obligations under Regulation FD: press releases, SEC filings, public conference calls, or our website. We routinely post important information on our website at www.eqcre.com, including information that may be deemed to be material.

RISK FACTORS Item 1A. Risk Factors. Before making an investment decision, you should carefully consider the following risk factors together with all of the other information contained in this Annual Report on Form 10-K. Risks Related to Our Business If we are unsuccessful in identifying and completing investments that we believe are strategically compelling, we may decide to sell, liquidate or otherwise exit our business in one or more transactions, which could materially and adversely impact us, including our stock price. We continue to evaluate potential investment opportunities in a range of property types. We are seeking to reinvest the significant cash balances we have accumulated, but we cannot provide any assurances that we will be successful in identifying 6 investments that we believe are strategically compelling and completing such transactions on favorable terms or at all. Our ability to identify and consummate investments is subject to significant risks, including the following: • we may be unable to identify attractive investment opportunities; • we may be unable to make an acquisition and/or investment because of competition from other real estate investors, such as private real estate companies, publicly traded REITs, non-traded REITs and institutional investment funds; and • we may be unable to finance investments on favorable terms or at all. If we are unable to successfully complete any investments, we may sell or liquidate the Company or otherwise exit our business through one or more transactions. The Board of Trustees and management regularly evaluate the best course of action for the Company and have not set a timetable for making any decision regarding a sale, liquidation or exit of the Company, and the timing and manner of any such sale, liquidation or exit may be viewed unfavorably. If a sale, liquidation or other exit occurs, or does not occur in a time frame or manner viewed favorably, our stock price could be negatively impacted. We may make investments that are viewed unfavorably by our shareholders, which could materially and adversely affect our stock price. We may make investments that are viewed unfavorably by our shareholders. We evaluate a range of investments in a variety of property types, including portfolios of properties, individual properties and businesses, which vary in significance from relatively minor initial investments to transformative transactions. Our investors may view negatively any acquisition and/ or investment that we make for a number of reasons, including because they believe we overvalued the acquired assets or businesses, they dislike the property type or types, quality or location of the acquired assets or businesses, they view the initial investment as small and therefore requiring substantially more time to complete the repositioning of our portfolio, or they disfavor the management or other personnel involved in any acquired businesses. If we make investments that are viewed unfavorably by our shareholders, it could negatively affect our stock price. We may incur significant costs pursuing investment opportunities that we may not consummate, which could adversely affect our results of operations. We have incurred and may continue to incur costs such as diligence, legal, advisory and consulting fees in connection with pursuing investments that we ultimately may not consummate, which could adversely affect our results of operations. We may encounter unanticipated difficulties and costs relating to integrating any properties or businesses we acquire, particularly if outside of the office sector, which could materially and adversely affect us. We may encounter unanticipated difficulties and expenditures relating to any properties or businesses we acquire. For example, notwithstanding pre-investment due diligence, we could become subject to unknown liabilities without any or limited recourse against the seller, including without limitation tenant claims, vendor claims, indemnification and other claims, and we may incur higher than expected property operating and capital costs. In addition, we may experience unexpected adverse market changes, including without limitation, re-leasing difficulties, occupancy and rental declines. For these and other reasons, we may not successfully integrate any properties or businesses we acquire, particularly if outside of the office sector, and may not achieve the returns we expected, which could have a material adverse effect on us. To the extent we are unable to complete dispositions at all, or we make any dispositions on unfavorable terms, it could adversely affect us. To the extent we seek to dispose of assets, we may not be able to complete sales in a timely manner, if at all, and any such dispositions could be made on unfavorable terms, which could adversely affect us. We could incur significant costs and liabilities in connection with the dispositions of any properties, including through indemnification protection we provide to purchasers, which could adversely affect us. We may also provide seller financing in connection with the disposition of certain properties. If any such properties fail to meet financial projections, perform poorly or decline in value, then the purchaser may not have sufficient funds to make required interest and principal payments due on such seller financing, which could adversely affect us. Market disruption caused by economic uncertainty and an overall slowdown in the office leasing market following the COVID-19 pandemic, including remote and hybrid working trends and other factors impacting the demand for office space, may continue to materially adversely affect us, including by impacting overall office demand, the long-term value of our properties, our growth prospects, our results of operations and our financial condition. Our business has been and is continuing to be impacted by economic uncertainty and an overall slowdown in the office leasing market following the COVID-19 pandemic due to a variety of factors, including tenant uncertainty regarding office 7 space needs given the evolving remote and hybrid working trends and other factors impacting the demand for office space. The majority of our tenants’ employees are currently working at least in part remotely, with many businesses reassessing their long- term demand for office space, which could adversely affect our ability to successfully re-lease our properties, the lease terms we are able to negotiate and the long-term value of our office properties. In addition, any future outbreaks of variants of the COVID-19 virus, or another pandemic, which result in the renewed imposition by governmental authorities of stay-at-home orders, quarantines, closures and other restrictions could materially and adversely affect us. Overall, our business has experienced a significant reduction in leasing interest and activity as well as parking revenue when compared to pre-pandemic levels. As of December 31, 2023 and December 31, 2019, our comparable property portfolio was 81.2% and 91.5% leased, respectively. The duration of these business disruptions continues to be unknown at this time, and we currently are not able to estimate the full impact of the overall slowdown in the office leasing market on our business. For the above reasons, economic uncertainty and remote and hybrid working trends have and may continue to materially adversely affect us, including by impacting overall office demand, the long-term value of our properties, our growth prospects, our results of operations and our financial condition. The failure of one or more of our tenants to pay rent due to market disruption, economic recession or for any other reason could materially and adversely affect us, including our results of operations. Our performance depends on the financial condition of our tenants and their ability to fulfill their lease obligations. Overall market disruption has adversely affected some of our tenants’ businesses, and we cannot predict the impact on our results of operations. Such disruption could impact the markets in which our properties are located and exacerbate the risk that our tenants will not be able to meet their lease obligations. Tenants with significant debt obligations may be unable to pay existing debt or rent payments, rising interest rates, and/or suffer other hardships resulting from economic recession, which could result in tenant requests for rent relief arrangements, tenant default, and/or tenant bankruptcies. We would be harmed if one or more of our major tenants, or a number of our smaller tenants, were to experience financial difficulties, including bankruptcy, insolvency or a general downturn of business. As of December 31, 2023, our portfolio was comprised of four properties, and the failure of one or more of our tenants to pay all or a substantial portion of their rent obligations could materially and adversely affect us, including our results of operations. If any of our major tenants, or a significant number of our smaller tenants, were to stop paying rent or otherwise experience a downturn in their business, or a weakening of their financial condition, such an event could have a material adverse effect on our business and results of operations. We may make investments in assets that we do not control, including in joint ventures with third parties, which may subject us to various risks, including limited decision-making authority, reliance on our joint venture partners’ financial condition and the risk of disputes with our joint venture partners, which could adversely affect us. We may make investments in assets that we do not control, including joint venture partnerships, or other structures with third parties. We also may make investments in which we share responsibility for managing the affairs of a business, property or partnership. If we enter into any joint ventures or similar ownership structures, we may have limited decision-making authority. In addition, we may face the risk of disputes with our joint venture partners, including without limitation potential deadlocks in making major decisions and restrictions on our ability to exit the joint venture. Any disputes that may arise between us and any joint venture partners may result in litigation or arbitration. We may also face risks associated with any joint venture partners’ financial condition, including, among other things, the risk of bankruptcy and/or failure to fund their share of required capital contributions. As a result, we may be exposed to liabilities in excess of our share of any joint venture. Any joint venture partners may also have business interests or goals that are inconsistent with our business interests or goals and may be in a position to take actions contrary to our policies or objectives. We may, in specific circumstances, be liable for the actions of any joint venture partners. We also may invest in public securities, unsecured debt and third-party mortgages which we do not control. Any of the foregoing may have a material adverse effect on our business, financial condition and results of operations. We may not decrease our general and administrative expenses proportionally with any reduction in the size of our portfolio, which could adversely affect us, including our results of operations. Because our current strategy is to grow through investments, we maintain a level of staffing that we believe will enable us to effectively identify investment opportunities and integrate any investments that we complete. As a result of this strategy, our general and administrative expenses may be higher than if we were not seeking growth through investments. If we are unable to grow through investments, and do not decrease our general and administrative expenses, our profitability and our results of operations could be adversely affected. 8 We derive a substantial portion of our revenues from four properties, and losses at any one of our properties could materially and adversely affect us. As of December 31, 2023, we owned four office properties and, as a result, any events that negatively impact one or more of our properties, such as a natural disaster, could materially and adversely affect us, including our financial condition and results of operations. We may be unable to renew leases, re-lease properties as leases expire or lease vacant spaces on favorable terms, which could materially and adversely affect us. As of December 31, 2023, leases representing 17.1% of our portfolio square footage and 15.7% of our annualized rental revenue will expire by the end of 2024 and leases representing 28.2% of our portfolio square footage and 26.6% of our annualized rental revenue will expire by the end of 2025. For more information on how we calculate lease expirations, please see “Management’s Discussion and Analysis of Financial Condition and Results of Operations—Property Operations.” We expect that many of our current tenants will decline to renew their leases when they expire in 2024, and other tenants may also decline to renew their leases. We also cannot assure you that any leases that are renewed will have terms as economically favorable as the expiring lease terms. If tenants do not renew their leases as they expire, we cannot provide any assurance that we will be able to find new tenants or that our properties will be re-leased at rental rates equal to or above the current rates in place. To retain tenants as leases expire and attract new tenants, we may be required to make significant capital investments in our properties and offer substantial rent abatements, tenant improvement allowances, early termination rights or below-market renewal options. We may experience significant costs in connection with re-leasing our properties, which could materially and adversely affect us. Our inability to renew leases, re-lease properties as leases expire or lease vacant space on favorable terms could materially and adversely affect us. Significant competition for tenants may increase our costs or reduce rents which could materially and adversely affect us. We encounter significant competition for tenants at all of our properties. Some competing properties may be newer, better located or otherwise more attractive to tenants. Competing landlords may offer available space at lower rents or on other more attractive terms than we offer at our properties. This competition may affect our ability to attract and retain tenants and may increase our costs or reduce the rents we are able to charge, which could materially and adversely affect us. Our reliance on CBRE, Inc., or CBRE, or another third party for property management services may have a negative effect on our financial condition and results of operations. We have engaged CBRE to provide property management services for our properties pursuant to a master property management agreement. The successful operation and management of our properties requires significant coordination between us and CBRE. Additionally, CBRE can terminate the property management agreement, as a whole or as to any one or more of our properties, without cause upon providing three months’ notice, and we are permitted to terminate the property management agreement, as a whole or as to any one or more of our properties, without cause upon 60 days’ notice. If we are unable to successfully coordinate with CBRE or another third party with respect to property management or the property management agreement with CBRE is terminated, in whole or in part, our operations could be disrupted, which may have a negative effect on our financial condition and results of operations. High interest rates, inflation, increased regulation and political instability could lead to increased market volatility or recession, which could materially and adversely affect us. In an effort to combat inflation, the Federal Reserve has imposed significant interest rate hikes, and interest rates may further increase in the near future. The Federal Reserve’s action, coupled with other macroeconomic factors, may trigger a recession in the United States, globally, or both. Current and potential tenants of our properties may be adversely impacted by inflation and rising interest rates, which could negatively impact current and prospective tenants’ ability to pay rent and as a result negatively impact the overall demand for our properties. Such adverse impacts on our tenants may cause increased vacancies, which may add pressure to lower rents and increase our re-leasing costs. Any such impacts may materially and adversely affect us. We may also encounter disruptions in one or more of the markets in which we operate due to increased regulation and political instability. Any of these factors could lead to increased market volatility or recession, the result of which could adversely impact our tenants, and, as a result, our occupancy rates, rental rates, rent collections, lease renewals, pursuit of new tenants and the overall value of our office properties, which could materially and adversely affect us. Increased interest rates would increase our interest costs on any future debt we incur, which could adversely affect us. The increase in interest rates could impact our ability to complete potential investments. In addition, to the extent we incur any debt in the future, including in connection with any potential investments, increased interest rates would cause our interest 9 costs to be higher, which could adversely affect our cash flow, ability to pay principal and interest on debt, cost of refinancing debt when it becomes due and our ability to make distributions to our shareholders. Additionally, if we choose to hedge any interest rate risk, we cannot assure that any such hedge will be effective or that our hedging counterparty will meet its obligations to us. Increased interest rates also could adversely affect the value of our properties to the extent that it decreases the amount buyers may be willing to pay for our properties. As a result, increased interest rates, including any future increases in interest rates, could adversely affect us. The loss of one or more members of our senior leadership team, particularly our Chair, President and Chief Executive Officer, could materially and adversely affect us. Our success, including our ability to complete investments and manage our operations, depends to a significant degree upon the efforts of our senior leadership team, particularly our Chair, President and Chief Executive Officer. Following the passing in May 2023 of our former Chairman Sam Zell, our Board appointed our President and Chief Executive Officer to serve as our Chair in addition to continuing in his roles as President and Chief Executive Officer. The loss of our Chair, President and Chief Executive Officer or one or more of the other members of our senior leadership team could materially and adversely affect us. We can increase our leverage without any limits under our governing documents, which may be viewed unfavorably by our shareholders and could result in a decline in our stock price. Our governing documents do not limit the amount of debt we may incur. In connection with potential investments, we may incur debt and significantly increase our leverage, which could reduce cash available for distributions and be viewed unfavorably by our shareholders, resulting in a decline in our stock price. Future impairment charges could materially and adversely affect us, including our results of operations in the period for which the charge occurs. We periodically evaluate the recoverability of the carrying values of each of our properties. As part of this evaluation, we compare the current carrying value of the asset to the estimated undiscounted cash flows that are directly associated with the use and ultimate disposition of the asset. Our estimated cash flows are based on several key assumptions, including anticipated hold periods, assumptions regarding the residual value upon disposition, including the exit capitalization rate, rental rates, costs of tenant improvements, and leasing commissions. These key assumptions are subjective in nature and could differ materially from actual results. Additionally, circumstances may cause us to alter the hold period of an asset or asset group, which may result in an impairment loss and such loss could be material to the Company’s financial condition or operating performance. To the extent that the carrying value of the asset exceeds the estimated undiscounted cash flows, an impairment loss is recognized equal to the excess of carrying value over fair value. Any future impairment could materially and adversely affect us, including our results of operations in the period in which the charge is taken. Any failure to maintain effective internal controls could materially and adversely affect us. Effective internal and disclosure controls are necessary for us to provide reliable financial reports and effectively prevent fraud and to operate successfully as a public company. Our internal controls over financial reporting and operations may not prevent or detect financial misstatements or loss of assets due to human error, management override of controls or fraud. Effective internal controls can provide only reasonable assurance regarding financial statement accuracy, public disclosures and safeguarding of assets. Any failure to maintain effective controls or timely effect any necessary improvement of our internal and disclosure controls could harm operating results or cause us to fail to meet our reporting obligations, which could affect our ability to remain listed with the New York Stock Exchange, or NYSE. Ineffective internal and disclosure controls could also cause investors to lose confidence in our reported financial information, which would likely have a negative effect on the per share trading price of our securities. Any failure to maintain effective internal controls could materially and adversely affect us. We may become subject to litigation which could materially and adversely affect us. We may become subject to litigation, including, but not limited to, claims relating to our operations, corporate transactions, dispositions and investments and otherwise in the ordinary course of our business, that could have a material adverse effect on us. Some of these claims could result in significant defense costs and potentially significant judgments against us, which may not be covered by insurance. Protracted litigation also may divert management’s and our Trustees’ attention away from our business. We cannot provide any assurance regarding the outcome of any claims that may arise in the future. We also have agreed to indemnify our present and former trustees, officers and property managers in connection with litigation in which they are named or threatened to be named as a party in their capacity as trustees, officers and property managers which can be expensive. Any fines, judgments or settlements that exceed our insurance coverage and any indemnification costs that we are required to pay could materially and adversely affect us. 10 Any environmental contamination or other environmental liabilities could materially and adversely affect us. Under various federal, state and local laws and regulations, as the current or former owner or operator of real estate, we may be liable for costs and damages resulting from the presence or release of hazardous substances, including waste or petroleum products, at, on, in, under or from such property, including costs for investigation, removal or remediation of such contamination and for natural resource damages arising from such contamination. Such laws often impose liability without regard to whether the owner or operator knew of, or was responsible for, the presence of such contamination, and the liability may be joint and several. In addition, the presence of contamination or the failure to remediate contamination at our properties may expose us to third-party liability for costs of remediation and/or personal injury or property damage, adversely affect our ability to lease or sell such property, or adversely affect our ability to borrow using such property as collateral. Environmental laws may create liens on contaminated sites in favor of the government for damages and costs it incurs to address such contamination. If contamination is discovered on our properties, environmental laws also may impose reporting requirements and/or restrictions on the manner in which those properties may be used or businesses may be operated, and these reporting requirements and/or restrictions may require significant expenditures. Additionally, we may remain responsible for costs and liabilities arising from environmental issues related to representations and warranties we make in sales agreements for sold properties. We also may be liable for the costs of removal or remediation of hazardous substances or waste at disposal or treatment facilities if we arranged for disposal or treatment of hazardous substances at such facilities, whether or not we own or operate such facilities. In addition, future environmental investigation and remediation costs, including capital expenditures for environmental projects, may increase because of new laws and regulations, changing interpretations and stricter enforcement of current laws and regulations by regulatory authorities, expanding groundwater and other testing requirements, and new information on emerging contaminants such as per- and polyfluoroalkyl substances (“PFAS”), as well as uncertainty regarding remediation methods for such emerging contaminants. Some of our current or sold properties have been or may in the future be impacted by releases of hazardous substances or petroleum products. Such contamination may arise from a variety of sources, including historic uses of our properties for commercial or industrial purposes, spills of such materials at adjacent properties, or releases from tanks used on our or nearby properties to store petroleum or hazardous substances. Additionally, our tenants’ operations, current and former operations in the vicinity of our properties, such as the presence of underground storage tanks, or activities of unrelated third parties, may have affected or may in the future affect the environmental condition of our properties. We, our tenants, and our properties are subject to various federal, state and local regulatory requirements related to environmental, health and safety matters, such as environmental laws, state and local fire and safety requirements, building codes and land use regulations. Failure to comply with these requirements could subject us or our tenants to governmental fines or private litigant damage awards. In addition, compliance with these requirements, including new requirements or stricter interpretation of existing requirements, may require us or our tenants to incur significant expenditures. We do not know whether existing requirements will change or whether future requirements, including any requirements that may emerge from pending or future climate change laws or regulations, will develop. Environmental noncompliance liability also could impact tenants’ ability to make rental payments to us, and our reputation could be negatively affected if we or our tenants violate environmental, health or safety laws or regulations. Buildings and other structures on properties that we currently own or operate or formerly owned or operated or those we acquire or operate in the future contain, may contain, or may have contained, asbestos-containing material, or ACM. Environmental, health and safety laws require that ACM be properly managed and maintained, and include requirements to undertake special precautions, such as removal or abatement, if ACM would be disturbed during maintenance, renovation, or demolition of a building, potentially resulting in substantial costs. Moreover, laws regarding ACM may impose fines and penalties on owners, employers and operators, and we may be subject to liability for releases of ACM into the air in our current or sold buildings and third parties may seek recovery from owners or operators of real property for personal injury associated with ACM. 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 also can 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. The presence of mold or other airborne contaminants in our current or sold buildings could expose us to costs and liabilities to address these issues, including from third parties if property damage or personal injury occurs. 11 We may be adversely affected by laws, regulations or other issues related to climate change, including the physical impacts of climate change on our properties. The federal government and some of the states and localities in which our properties are located have enacted and may enact in the future certain climate change laws and regulations, including laws and regulations with respect to the regulation of carbon footprints and greenhouse gas emissions associated with buildings and “green” building codes. Although these laws and regulations have not had any known material adverse effects on our business to date, they could result in substantial costs, including compliance costs, increased energy costs, retrofit costs and construction costs, monitoring and reporting costs, and capital expenditures for environmental control facilities and other new equipment, as well as increasing (or making unavailable) property insurance on terms we find acceptable. Furthermore, our reputation could be negatively affected if we violate climate change laws or regulations. We cannot predict how future laws and regulations, or future interpretations of current laws and regulations, related to climate change will affect our business, results of operations and financial condition. Also, the potential physical impacts of climate change itself on our properties are highly uncertain, and would be particular to the geographic circumstances in areas in which our properties are located. These may include changes in rainfall and storm patterns and intensities, resulting in flooding, wind damages, land erosion, droughts, wildfire risk and water shortages, rising sea levels, heatwaves and other changing temperatures. To the extent these events result in significant damage to or closure of any of our buildings, our operations and financial performance could be adversely affected through lost tenants and an inability to lease or re-lease the space. In addition, these events could result in significant expenses to restore or remediate a property, increases in fuel (or other energy) prices or a fuel shortage, and increases in the costs of insurance if they result in significant loss of property or other insurable damage. These impacts may adversely affect our business, financial condition and results of operations. We rely on information technology in our operations, and any material failure, inadequacy, interruption or security failure of that technology could harm our business. We rely on information technology (“IT”) networks and systems, including the Internet, to process, transmit and store electronic information and to manage or support a variety of our business processes, including financial transactions and maintenance of records, which may include personal identifying information of tenants and lease data. We rely on commercially available systems, software, tools and monitoring to provide security for processing, transmitting and storing confidential tenant information, such as individually identifiable information relating to financial accounts. As our reliance on technology has increased, so have the risks posed to our systems, both internal and those we have outsourced to third party service providers. In addition, information security risks have generally increased in recent years due to the rise in new technologies, including artificial intelligence, and the increased sophistication and activities of perpetrators of cyber attacks. Although we have taken steps to protect the security of the data maintained in our information systems, it is possible that our security measures will not be able to prevent the systems’ improper functioning, or the improper disclosure of personally identifiable information such as in the event of cyber attacks. Security breaches, including physical or electronic break-ins, computer viruses, attacks by hackers, including ransom attacks, and similar breaches, can create system disruptions, shutdowns or unauthorized disclosure of confidential information. The costs related to cyber attacks or other security threats or disruptions may not be fully insured or otherwise indemnified. Any failure to maintain proper function, security and availability of our information systems could interrupt our operations, damage our reputation, subject us to liability claims or regulatory penalties and could materially and adversely affect us. Any failure of one or more of our current or potential tenants to provide accurate or complete financial information could prevent us from identifying tenant problems that could materially and adversely affect us. We rely on information from our current and potential tenants to evaluate tenants’ credit risk as well as for ongoing risk management. To the extent the procedures we use to evaluate a tenant’s credit risk are not sufficient, or a tenant fails to provide appropriate, accurate and complete financial information to us, our ability to identify tenant problems in a timely manner, or at all, could be adversely impacted. Such inability to identify current or potential tenants’ problems could materially and adversely affect us. Risks Related to the Real Estate Industry Real estate ownership creates risks and liabilities that could materially and adversely affect us. Our economic performance and the value of our real estate assets, and consequently the value of our securities, are subject to risks inherently associated with real estate ownership, including: • • changes in supply of or demand for properties in areas in which we own buildings; the illiquid nature of real estate markets, which limits our ability to sell our assets rapidly or to respond to changing market conditions; 12 • • • • • • • • the subjectivity of real estate valuations and changes in such valuations over time; property and casualty losses; the ongoing need for property maintenance and repair, and the need to make expenditures due to changes in governmental regulations, including, but not limited to, the Americans with Disabilities Act; the inability of tenants to pay rent; competition from the development of properties in the markets in which we own property and the quality of such competition, such as the attractiveness of our properties as compared to our competitors’ properties based on considerations such as convenience of location, rental rates, amenities and safety record; civil unrest, acts of war, acts of God, including, but not limited to, earthquakes, hurricanes, pandemics and other natural disasters (which may result in uninsured losses), and other factors beyond our control; legislative, tax and regulatory developments that may occur at the federal, state and local levels that have direct or indirect impact on the ownership, leasing and operation of our properties; and litigation incidental to our business. If any of the foregoing events occur, our properties may generate less revenues than expected and that may not be sufficient to meet our operating expenses, including debt service and capital expenditures, which could have a material adverse effect on us. Potential losses may not be covered by our insurance policies, which could materially and adversely affect us. We do not carry insurance for certain losses such as loss from riots, war or acts of God. For other potential losses relating to acts of terrorism, environmental liabilities, hurricanes, earthquakes and floods, we currently carry insurance but our insurance policies may contain limitations, including large deductibles, co-payments and general policy limits. We cannot provide any assurances that any losses we incur following the COVID-19 or another pandemic will be covered by our insurance policies, and any such coverage may be subject to limitations. In the future, we may be unable to renew or duplicate our current insurance coverage at adequate levels or at reasonable prices or at all. In addition, insurance companies may no longer offer coverage against certain types of losses, such as losses due to terrorist acts, environmental liabilities, or other catastrophic events including hurricanes and floods, or, if offered, the expense of obtaining these types of insurance may not be justified. If an uninsured loss or a loss in excess of our insured limits occurs, we could lose all or a portion of the capital we have invested in a property, as well as the anticipated future revenue from the property, but still remain obligated for certain financial obligations related to the property. If any of our properties were to experience a catastrophic loss, it could seriously disrupt our operations, delay revenue and result in large expenses to repair or rebuild the property. If we experience losses that are ultimately uninsured, it could materially and adversely affect us. Local, state or national measures and regulations could restrict our ability to enforce tenants’ contractual rental obligations, which could materially and adversely affect us. Local, state or national authorities may enact, expand or extend certain measures or regulations, including in connection with the economic uncertainty following the COVID-19 or another pandemic. These measures or regulations include, by way of example, rent-freezes, eviction moratoria, rent control or rent stabilization efforts, or court closures, any of which could impose direct or indirect restrictions on our ability to enforce tenants’ contractual rental obligations, which could materially and adversely affect us. We cannot predict what laws or regulations will be enacted in the future, how future laws or regulations will be administered or interpreted, or how future laws or regulations will affect us or our properties. Compliance with new laws or regulations, or stricter interpretation of existing laws, may require us or our tenants to incur significant expenditures, impose significant liability, restrict or prohibit business activities and could cause a material adverse effect on us. Actual or threatened terrorist attacks, crimes, shootings, riots, other acts of violence or other incidents beyond our control may materially and adversely affect us. We have significant investments in large metropolitan markets that have been or may be in the future the targets of actual or threatened terrorism attacks, crimes, shootings, riots, other acts of violence or other incidents beyond our control. As a result, tenant demand for our office space could decline if some tenants in these markets choose to relocate their businesses to other markets or to lower-profile office buildings within these markets that may be perceived to be less likely targets of future incidents. In addition, our office properties could be damaged, directly or indirectly, from future terrorist attacks or other acts of violence. If a future attack or incident occurs, it could require us to close a property for some time, it could increase vacancies at our properties, it could necessitate leasing our properties on less favorable terms, and it could expose us to civil liability, all of which could materially and adversely affect us. 13 Changes in accounting pronouncements or auditing standards may materially and adversely affect our financial statements, our tenants’ credit quality and our ability to secure long-term leases and renewal options. Accounting policies and methods are fundamental to how we record and report our financial condition and results of operations. Uncertainties posed by various initiatives of accounting standard-setting by the Financial Accounting Standards Board and the Securities and Exchange Commission, which create and interpret applicable accounting standards for U.S. companies, as well as auditing and related standards set by the Public Company Accounting Oversight Board, may change the financial accounting, reporting and auditing standards or their interpretation and application of these standards that govern the preparation of our financial statements and the scope of our independent audit. These changes could have a material impact on our reported financial condition and results of operations. In some cases, we could be required to apply a new or revised standard retroactively, resulting in potentially material restatements of prior period financial statements. Similarly, these changes could have a material impact on our tenants’ reported financial condition or results of operations or could affect our tenants’ preferences regarding leasing real estate. If governmental authorities in the future seek to acquire part or all of our properties through eminent domain, we may not receive adequate compensation or recover costs associated with divesting the properties. Government authorities, including federal and state governments as well as municipalities and other government subdivisions, may, in certain circumstances, seek to acquire part or all of our properties through eminent domain proceedings. While we may seek to contest these proceedings, such contests may be costly and could divert management’s attention away from our business, and there can be no assurance that a governmental authority will not succeed in acquiring part or all of our properties. In such event, there is a risk that we will not receive adequate compensation for the assets acquired. Risks Related to Our Securities We may not distribute any of our significant existing cash balances to shareholders, which could be viewed unfavorably by our shareholders and materially and adversely affect our share price. Any distributions will be made at the discretion of our Board of Trustees and will depend upon various factors that our Board of Trustees deems relevant. We currently hold a significant amount of cash and cash equivalents ($2.2 billion as of December 31, 2023) which enables us to pursue investments and, as a result, we may elect not to distribute any of our existing cash to our shareholders. To the extent that our actual distributions are less than expected by investors, it could materially and adversely affect our share price. A substantial portion of our assets is currently held in cash, which is subject to risk of loss and potentially decreasing rates of return, which could materially and adversely affect us, including limiting our growth. As of December 31, 2023, we held $2.2 billion of cash and cash equivalents. We currently invest the majority of our cash in bank deposits with investment grade financial institutions. Nearly all of our cash and bank deposits are not insured by the Federal Deposit Insurance Corporation, or the FDIC. In addition, interest rates could decline, which could adversely affect our results of operations. Therefore, our cash and any bank deposits or other investments that we now hold or may acquire in the future may be subject to risks, including the risk of loss or of reduced value, interest rate risk, and liquidity risk. Changes in market conditions could adversely affect the market price of our common shares. As with other publicly traded equity securities, our stock price depends on various market conditions that may change from time to time. Among the market conditions that may affect the value of our common shares are the following: • • • • • • • • the extent of investor interest in our securities; the general reputation of REITs and the attractiveness of our equity securities in comparison to other equity securities, including securities issued by other real estate-based companies; our underlying asset value; national and global economic conditions; interest rates; changes in tax laws; our financial performance; and general stock and bond market conditions. Changes in one or more of these market conditions could cause the market price of our common shares to decline. 14 The number of our common shares available for future issuance or sale could adversely affect the per share trading price of our common shares and may be dilutive to current shareholders. Our declaration of trust authorizes our Board of Trustees to, among other things, issue additional shares of capital stock without shareholder approval. We cannot predict whether future issuances or sales of our common shares or the availability of shares for resale in the open market will decrease the per share trading price of our common shares. The issuance of substantial numbers of our common shares in the public market, including, but not limited to, in connection with any future transaction involving the Company or upon conversion of our Series D preferred shares, or the perception that such issuances might occur, could adversely affect the per share trading price of our common shares. In addition, we may issue our common shares or other long-term equity awards under the Equity Commonwealth 2015 Omnibus Incentive Plan, as amended. Any such future issuances may be dilutive to existing shareholders. Conversion of our Series D preferred shares may dilute the ownership interests of existing shareholders. The conversion of some or all of our Series D preferred shares may dilute the ownership interests of existing shareholders. Risks Related to Our Organization and Structure Ownership limitations and certain provisions in our declaration of trust and bylaws, as well as certain provisions of Maryland law, may deter, delay or prevent a change in our control or unsolicited acquisition proposals that otherwise could be viewed favorably by our shareholders. Our declaration of trust and bylaws prohibit any shareholder other than certain persons who have been exempted by our Board of Trustees from owning (directly and by attribution) more than 9.8% of the number or value of shares of any class or series of our outstanding shares of beneficial interest, including our common shares. These provisions are intended to assist with our REIT compliance under the Code and otherwise promote our orderly governance. However, these provisions also inhibit acquisitions of a significant stake in us and may deter, delay or prevent a change in our control or unsolicited acquisition proposals that a shareholder may consider favorable. Additionally, provisions contained in our declaration of trust and bylaws or under Maryland law may have a similar impact, including, for example, provisions relating to: the authority of our Board of Trustees to fill most vacancies on our Board of Trustees; the fact that only the Chair of the Board of Trustees, our Chief Executive Officer, our President, a majority of our Trustees or the holders of 10% of our common shares may call a special meeting of shareholders; and advance notice requirements for shareholder proposals. Furthermore, our Board of Trustees has the authority to create and issue new classes or series of shares (including shares with voting rights and other rights and privileges that may deter a change in control) and issue additional common shares. The authorization and issuance of a new class of capital stock or additional common shares could have the effect of delaying or preventing someone from taking control of us, even if a change in control could be viewed favorably by our shareholders. Our Board of Trustees has the authority, without shareholder approval, to opt into certain provisions of Maryland law that could inhibit changes in control which otherwise could be viewed favorably by our shareholders. Although we currently have opted out of certain provisions of Maryland law that otherwise could have the effect of inhibiting a third party from making a proposal to acquire us or of impeding a change of control, our Board of Trustees has the authority, without shareholder approval, to opt back into these provisions. If our Board of Trustees decides to opt back into these provisions, it could impede a change of control transaction that could provide the holders of our common shares with the opportunity to realize a premium over the then-prevailing market price of such shares, including: • • “business combination moratorium/fair price” provisions that, subject to limitations, prohibit certain business combinations between us and an “interested shareholder” (defined generally as any person who beneficially owns 10% or more of the voting power of our shares or an affiliate thereof) for five years after the most recent date on which the shareholder becomes an interested shareholder, and thereafter imposes stringent fair price and super- majority shareholder voting requirements on these combinations; and “control share” provisions that provide that “control shares” of our company - defined as shares which, when aggregated with other shares controlled by the shareholder, entitle the shareholder to exercise one of three increasing ranges of voting power in electing trustees - acquired in a “control share acquisition” - defined as the direct or indirect acquisition of ownership or control of “control shares” from a party other than the issuer - have no voting rights except to the extent approved by our shareholders by the affirmative vote of at least two-thirds of all the votes entitled to be cast on the matter, excluding all interested shares, and are subject to redemption in certain circumstances. 15 Our Board of Trustees has the authority, without shareholder approval, to opt into these provisions at any time, which could inhibit changes in control which otherwise could be viewed favorably by our shareholders. Our Operating Trust’s organizational documents contain provisions that may delay, defer or prevent unsolicited acquisitions of us or changes in our control that otherwise could be viewed favorably by our shareholders. Our Operating Trust’s organizational documents contain provisions that may delay, defer or prevent unsolicited acquisitions or changes in our control that might involve a premium price for the Company’s common shares. These provisions include, among others: • • • • • • redemption rights of qualifying parties; prohibition against our removal as the trustee of the Operating Trust with or without cause; transfer restrictions on the OP Units held directly or indirectly by us; our ability as trustee in some cases to amend the organizational documents of the Operating Trust without the consent of the other holders of OP Units; the right of the holders of OP Units to consent to mergers involving us under specified circumstances; and the right of the holders of OP Units to consent to our withdrawal as the sole trustee of the Operating Trust. These provisions could discourage third parties from making proposals involving an unsolicited acquisition of us or change of our control that otherwise could be viewed favorably by our shareholders. As an UPREIT, we are a holding company with no direct operations and will rely on distributions received from our Operating Trust to make distributions to our shareholders. We are a holding company and conduct all of our operations through our Operating Trust, and we rely on distributions from our Operating Trust to make any distributions to our shareholders and to meet any of our obligations. The ability of our Operating Trust to make distributions to us will depend on its operating results and the ability of subsidiaries of our Operating Trust to make distributions to our Operating Trust, which could be subject to restrictions of any of its subsidiaries. In addition, the claims of our shareholders will be structurally subordinated to all existing and future liabilities and other obligations and any preferred equity of the Operating Trust and its subsidiaries, including in the case of any liquidation, bankruptcy or reorganization of our company. We may complete investments through issuance of OP units in tax-deferred contribution transactions, which could result in shareholder dilution and restrict our ability to sell such assets, which could adversely affect us. In the future, we may complete investments through tax-deferred contribution transactions in exchange for OP Units in the Operating Trust, which may result in shareholder dilution. In addition, such transactions may reduce the amount of tax depreciation we could deduct over the tax lives of the acquired properties and may require that we agree to protect the contributors’ abilities to defer recognition of taxable gain through restrictions on our ability to dispose of the acquired properties and/or the allocation of partnership debt to the contributors to maintain their tax bases. These restrictions could limit our ability to sell or finance an asset at a time, or on terms, that otherwise would be favorable to us. Our shareholders’ recourse against our Trustees and officers is limited by the terms contained in our declaration of trust and bylaws, which may be viewed unfavorably by our shareholders. Our declaration of trust limits the liability of our Trustees and officers to us and our shareholders for money damages to the maximum extent permitted under Maryland law. Under current Maryland law, our Trustees and officers will not have any liability to us and our shareholders for money damages other than liability resulting from: • • actual receipt of an improper benefit or profit in money, property or services; or active and deliberate dishonesty by the Trustee or officer that was established by a final judgment as being material to the cause of action adjudicated. Our declaration of trust and bylaws require us to indemnify any present or former Trustee or officer, to the maximum extent permitted by Maryland law, who is made or threatened to be made a party to a proceeding by reason of his or her service in that capacity. In addition, we may be obligated to pay or reimburse the expenses incurred by our present and former Trustees and officers without requiring a preliminary determination of their ultimate entitlement to indemnification. As a result, our shareholders’ recourse against our Trustees and officers is limited, which may be viewed unfavorably by our shareholders. 16 Our bylaws provide that actions by our shareholders against us or against our Trustees and officers, including derivative and class actions, may be referred to binding arbitration proceedings. As a result, our shareholders would not be able to pursue litigation for these disputes in courts against us or our Trustees and officers if the disputes were referred to arbitration. In addition, the ability to collect attorneys' fees or other damages may be limited, which may discourage attorneys from agreeing to represent parties wishing to commence such a proceeding. As a result, our shareholders’ recourse against our Trustees and officers is limited by the terms of our declaration of trust and bylaws, which may be viewed unfavorably by our shareholders. Conflicts of interest could arise in the future between the interests of the Company’s shareholders and the interests of OP Unitholders, which may impede business decisions that could benefit our shareholders. Conflicts of interest may exist or could arise in the future as a result of the relationships between the Company and its affiliates, on the one hand, and the Operating Trust or holders of OP Units, on the other. Our trustees and officers have duties to the Company under applicable Maryland law in connection with their management of the Company. At the same time, we, as trustee, have duties to the Operating Trust under Maryland law in connection with the management of the Operating Trust. The Company’s duties as trustee to the Operating Trust may come into conflict with the duties of our trustees and officers to the Company. Additionally, the organizational documents of the Operating Trust expressly limit our liability by providing that the Company will not be liable for monetary or other damages or otherwise for losses sustained, liabilities incurred or benefits not derived in connection with such decisions unless the Company acted with willful misfeasance, bad faith, gross negligence or reckless disregard of duty, and the act or omission was material to the matter giving rise to the loss, liability or benefit not derived. Moreover, the organizational documents of the Operating Trust provide that the Operating Trust may indemnify, and pay or reimburse reasonable expenses to, the Company and the Company’s and the Operating Trust’s present or former unitholders, trustees, officers or agents and any other persons acting on behalf of the Company that the Company may designate from and against all claims and liabilities by reason of his, her or its service in such capacity. The Operating Trust has the power, with the approval of the Company, to provide such indemnification and advancement of expenses. The provisions of Maryland law that allow the duties of a trustee to be modified by such organizational documents have not been resolved in a court of law, and we have not obtained an opinion of counsel covering the provisions set forth in the organizational documents of the Operating Trust that purport to waive or restrict our duties that would be in effect were it not for such organizational documents. We may change our operational, financing and investment policies without shareholder approval, and any future changes we may implement may be viewed unfavorably. Our Board of Trustees determines our operational, financing and investment policies and may amend or revise our policies, including our policies with respect to our intention to qualify for taxation as a REIT, investments, dispositions, growth, operations, indebtedness, capitalization and distributions, or approve transactions that deviate from these policies, without shareholder approval. Policy changes could adversely affect the market value of our common shares and our ability to make distributions to our shareholders. Further, our organizational documents do not limit the amount or percentage of indebtedness, funded or otherwise, that we may incur. We could significantly increase our leverage, which could increase the risk of default on our obligations. In addition, we could change our investment policies, including how we allocate our resources across our portfolio or the types of assets in which we seek to invest and how we address our exposure to interest rate risk, real estate market fluctuations and liquidity risk. Risks Related to Our Taxation as a REIT If we do not qualify as a REIT or fail to remain qualified as a REIT, we will be subject to U.S. federal income tax and potentially to additional state and local taxes which would reduce the amount of cash available for distribution to our shareholders. We believe that we have been organized and have operated in a manner to allow us to qualify us to be taxed under the Code as a REIT. However, we cannot be certain that, upon review or audit, the IRS will agree with this conclusion. Furthermore, Congress and the IRS might make changes to the tax laws and regulations, and the courts might issue new rulings, that make it more difficult, or impossible, for us to remain qualified as a REIT. We do not intend to request a ruling from the IRS as to our REIT qualification. As a REIT, we generally do not pay U.S. federal income tax on our net income that we distribute currently to our shareholders. However, actual qualification as a REIT under the Code depends on satisfying complex statutory requirements, for which there are only limited judicial and administrative interpretations. Many of the REIT requirements are highly technical and complex. Even a technical or inadvertent violation could jeopardize our REIT qualification. Our qualification as a REIT for U.S. federal income tax purposes depends on our satisfaction of certain asset, income, organizational, distribution, shareholder 17 ownership and other requirements on a continuing basis. The determination that we are a REIT requires an analysis of various factual matters and circumstances that may not be totally within our control. If we fail to qualify as a REIT for U.S. federal income tax purposes, and do not avail ourselves of certain savings provisions set forth in the Code, we likely would be subject to U.S. federal income tax at regular corporate rates. As a taxable corporation, we would not be allowed to take a deduction for distributions to shareholders in computing our taxable income or pass through long-term capital gains to individual shareholders at favorable rates. We also could be subject to increased state and local taxes. We would not be able to elect to be taxed as a REIT for four years following the year we first failed to qualify unless the IRS were to grant us relief under certain statutory provisions. If we failed to qualify as a REIT, we likely would have to pay significant income taxes, which likely would reduce our net earnings available for investment or distribution to our shareholders. If we fail to qualify as a REIT, such failure may adversely affect our ability to raise capital and to service our debt. This likely would have a significant adverse effect on our earnings and the value of our securities. In addition, we would no longer be required to pay any distributions to shareholders. If we fail to qualify as a REIT for U.S. federal income tax purposes and are able to avail ourselves of one or more statutory savings provisions set forth in the Code in order to maintain our REIT status, we would nevertheless be required to pay penalty taxes of $50,000 or more for each such failure. As of December 31, 2023, we owned three of our properties and approximately $867 million of cash and cash equivalents through a subsidiary entity which is intended to qualify as a REIT (a “Subsidiary REIT”), and we may in the future own other properties or assets through Subsidiary REITs or use other structures that include Subsidiary REITs. A Subsidiary REIT is subject to the various REIT qualification requirements and other limitations described herein that are applicable to us. If a Subsidiary REIT were to fail to qualify as a REIT: (i) that Subsidiary REIT would become subject to U.S. federal income tax and could become subject to increased state and local taxes, (ii) shares in such Subsidiary REIT would cease to be qualifying assets for purposes of the asset tests applicable to REITs and would cease to produce qualifying income for purposes of the income tests applicable to REITs, and (iii) it is possible that we would fail certain asset and income tests applicable to REITs, in which event we would fail to qualify as a REIT unless we avail ourselves of certain relief provisions. Even if we qualify and remain qualified as a REIT, we may face other tax liabilities that reduce our cash flow. Even if we qualify and remain qualified for taxation as a REIT, we may be subject to certain U.S. federal, state and local taxes on our income and assets, including taxes on any undistributed income, excise taxes, state or local income, property and transfer taxes, such as mortgage recording taxes, and other taxes. We are subject to U.S. federal and state income tax (and any applicable non-U.S. taxes) on the net income earned by our taxable REIT subsidiaries. Moreover, if we have net income from “prohibited transactions,” for example in connection with the dispositions of property held primarily for sale to customers in the ordinary course of business, that income will be subject to a 100% tax. Finally, some state and local jurisdictions may impose taxes, such as franchise taxes, on some of our income even though as a REIT we are not subject to U.S. federal income tax on that income because not all states and localities treat REITs the same way they are treated for U.S. federal income tax purposes. To the extent that we and our affiliates are required to pay federal, state and local taxes, we will have less cash available for distributions to our shareholders. With less rental revenue, in order to comply with the 75% gross income test, we may be required to reduce interest payments on our investments in cash and cash equivalents, make qualifying investments in real estate assets that satisfy this test, contribute cash to our taxable REIT subsidiary which is subject to U.S. federal and state income tax, or take other steps which could adversely affect our cash flow. One of the gross income requirements a REIT must satisfy each taxable year is that at least 75% of its gross income (excluding gross income from prohibited transactions and qualifying hedges) generally must be derived directly or indirectly from investments relating to real property or mortgages on real property. As of December 31, 2023, we had equity interests in four office properties and cash and cash equivalents of $2.2 billion. With a large cash balance, increased interest rates and fewer income-producing real properties, we receive less rental revenue as a percentage of our total revenue. In order to comply with the 75% gross income test for each taxable year, we may be required to reduce interest payments on our investments in cash and cash equivalents, contribute cash to our taxable REIT subsidiary which is subject to U.S. federal and state income tax, or take other steps which could adversely affect our cash flow. We may also be required to invest some or all of our cash and cash equivalents in qualifying investments in real estate assets, including mortgages on real property and investments in assets that we do not control, and such investments may have more risks than investments in cash and cash equivalents. Complying with REIT requirements may force us to forego and/or liquidate otherwise attractive investment opportunities. To qualify as a REIT, we must ensure that we meet the REIT 75% and 95% gross income tests annually and that, at the end of each calendar quarter, at least 75% of the value of our assets consists of cash, cash items, government securities and qualified real estate assets. The remainder of our investment in securities (other than government securities and qualified real 18 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, no more than 20% of the value of our total securities can be represented by securities of one or more taxable REIT subsidiaries, or TRS, and no more than 25% of the value of our assets can be represented by debt instruments issued by “publicly offered REITs.” If we fail to comply with these requirements 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 statutory relief provisions to avoid losing our REIT qualification and suffering adverse tax consequences. As a result, we may be required to liquidate from our portfolio, or contribute to a TRS, otherwise attractive investments in order to maintain our qualification as a REIT. These actions could have the effect of reducing our income, increasing our income tax liability, and reducing amounts available for distribution to our shareholders. In addition, we may be required to make distributions to shareholders at disadvantageous times or when we do not have funds readily available for distribution, and may be unable to pursue investments (or, in some cases, forego the sale of such investments) that would be otherwise advantageous to us in order to satisfy the source-of-income or asset-diversification requirements for qualifying as a REIT. Thus, compliance with the REIT requirements may hinder our ability to make, and, in certain cases, maintain ownership of certain attractive investments. REIT distribution requirements could adversely affect our ability to execute our business plan. We generally must distribute annually at least 90% of our “REIT taxable income” (determined before the deduction for dividends paid and excluding net capital gains) in order for U.S. federal corporate income tax not to apply to earnings that we distribute. To the extent that we satisfy this distribution requirement, but distribute less than 100% of our taxable income, we will be subject to U.S. federal corporate income tax on our undistributed taxable income. In addition, we will be subject to a 4% nondeductible excise tax if the actual amount that we pay out to our shareholders in a calendar year is less than a minimum amount specified under U.S. federal tax laws. We intend to make distributions to our shareholders to comply with the REIT requirements of the Code and avoid entity-level taxes. From time to time, we may generate taxable income greater than our income for financial reporting purposes prepared in accordance with U.S. generally accepted accounting principles, or GAAP, or differences in timing between the recognition of taxable income and the actual receipt of cash or between the deduction of expenses and actual payment of those expenses may occur. If we do not have other funds available in these situations, we could be required to (i) borrow funds on unfavorable terms, (ii) sell investments at disadvantageous prices, (iii) distribute amounts that would otherwise be invested in future investments, or (iv) make a taxable distribution of our common shares as part of a distribution in which shareholders may elect to receive our common shares or (subject to a limit measured as a percentage of the total distribution) cash to make distributions sufficient to enable us to pay out enough of our taxable income to satisfy the REIT distribution requirement. These alternatives could increase our costs or reduce our shareholders’ equity. Thus, compliance with the REIT requirements may hinder our ability to grow, which could adversely affect the value of our shares. Our transactions with our TRSs will cause us to be subject to a 100% penalty tax on certain income or deductions if those transactions are not conducted on arm’s length terms. A REIT may own up to 100% of the stock of one or more TRS. A TRS may hold assets and earn income that would not be qualifying assets or income if held or earned directly by a REIT. Both the subsidiary and the REIT must jointly elect to treat the subsidiary as a TRS. 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 stock or securities of one or more TRS. The tax 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. TRSs that we have formed are subject to and will continue to be subject to 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 by such TRSs to us. We believe that the aggregate value of the stock and securities of our TRSs has been and we anticipate that the aggregate value will continue to be less than 20% of the value of our total assets (including our TRS stock and securities). Furthermore, we have monitored and will continue to monitor the value of our respective investments in our TRSs for the purpose of ensuring compliance with TRS ownership limitations. In addition, we have scrutinized and will continue to scrutinize all of our transactions with our TRSs to ensure that they are entered into on arm’s length terms to avoid incurring the 100% excise tax described above. There can be no assurance, however, that we will be able to comply with the TRS limitation discussed above or to avoid application of the 100% excise tax discussed above. 19 The tax on “prohibited transactions” may limit our ability to engage in transactions which would be treated as sales for U.S. federal income tax purposes. A REIT’s net income from prohibited transactions is subject to a 100% tax. In general, prohibited transactions are sales or other dispositions of property, other than foreclosure property, held primarily for sale to customers in the ordinary course of business. We believe that the dispositions related to the repositioning of our portfolio along with other dispositions that we have made or that we might make in the future will not be subject to the 100% penalty tax; however, because application of the prohibited transactions tax could be based on an analysis of all of the facts and circumstances, there can be no assurance that the gains on some of our prior real estate sales, or any future real estate sales, will not be subject to the 100% prohibited transaction tax. There is a risk of changes in the tax law applicable to REITs. The IRS, the United States Treasury Department and Congress frequently review U.S. federal income tax legislation, regulations and other guidance. We cannot predict whether, when or to what extent new federal tax laws, regulations, interpretations or rulings will be adopted. Any legislative action may prospectively or retroactively modify our tax treatment and, therefore, may adversely affect taxation of us and/or our shareholders. Item 1B. Unresolved Staff Comments. None. Item 1C. Cybersecurity. The Company maintains a cybersecurity program focused on preventing, identifying and mitigating cyber threats applicable to its business as an owner and operator of commercial office properties. Our Board oversees our cybersecurity program through its Audit Committee, which meets regularly with the Company’s executive officers and senior personnel from the Company’s IT department, which manages the program on a day-to-day basis. The Company’s cybersecurity program is integrated into its overall risk management processes. Risk Management and Strategy The Company employs a number of cybersecurity measures intended to reduce the likelihood that cybersecurity incidents materialize, including: (i) employing a variety of reputable and recognized hardware, software and other security measures in the design and maintenance of our information technology and data security systems; (ii) conducting periodic testing and verification of information and data security systems, including engaging third-party assessors to perform penetration testing of our systems to identify vulnerabilities; (iii) confirming with our critical vendors whether they have had cyber breaches of their IT systems or otherwise involving Company information; (iv) verifying third-party IT system integrity through a review of System and Organization (“SOC”) audit review reports provided by certain of our vendors; and (v) providing onboarding and other periodic employee security awareness training relating to phishing and other scams, malware and various cyber-related risks. We have also engaged third-party vendors to assist with incident detection and monitoring and to implement and maintain other cybersecurity measures specific to our operations and portfolio properties. The Company has created and maintains processes that provide a playbook in the event of a cyber incident. These processes provide assessment and response tools designed to mitigate damage from attacks and integrate third-party digital forensics and legal providers and law enforcement in the Company’s response plan. The Company also has instituted a variety of safeguards to counter ransomware threats. The Company has integrated its cybersecurity program into its overall risk management processes by instituting corporate measures and protocols that apply to ensure ongoing operations in the event of a disaster or major business disruption affecting the corporate headquarters, infrastructure or key personnel, as well as similar processes in case of a crisis-related event at our portfolio properties. Our employee guidelines also address employee computer usage, including a variety of restrictions and protocols intended to enhance cybersecurity and reduce the risk of a successful cyber-attack. Material Effects from Risks of Cybersecurity Threats We do not believe any risks from cybersecurity threats, including any past cybersecurity incidents, have materially affected the Company, including our business strategy, results of operations or financial condition. There can be no assurances, however, that we or our third-party service providers will not experience a future system disruption, attack or security breach that materially impacts the Company, our business strategy, results of operations or financial condition. For more information 20 refer to “Item 1A. Risk Factors—Risks Related to Our Business—We rely on information technology in our operations, and any material failure, inadequacy or security failure of that technology could harm our business”. Board of Trustees’ and Management Oversight Our Board of Trustees oversees our cybersecurity program and initiatives through its Audit Committee. The Audit Committee, in consultation with management, actively oversees and manages the Company’s cybersecurity risk, including periodically reviewing our policies and procedures with respect to risk assessment and risk management. As part of its cybersecurity oversight role, the Audit Committee meets regularly with the Company’s executive officers and senior IT personnel to discuss the Company’s policies, procedures and other measures put in place to protect its business systems and information against cyber-related attacks and risks, as well as to discuss recent cyber and IT trends. Through the policies, plans, guidelines and processes the Company has implemented, any material cybersecurity incident would be reported to our executive officers as well as the Audit Committee and/or the Board. Cybersecurity Personnel Resources The Company’s cybersecurity program is managed by our IT department, which is led by our SVP - Information Technology, who has a Master of Business Administration degree and a Master Certification in Cybersecurity from Colorado State University. Our IT department has more than 25 years of combined experience. The members of our IT department have experience with network and system security, backup and recovery strategies and software design and implementation. Areas of substantial experience also include IT audits and anti-phishing training, as well as server installation, configuration and administration. Item 2. Properties. General. As of December 31, 2023, we had real estate investments totaling $411.9 million in four properties (eight buildings), that were leased to 98 tenants. We account for the operations of all our properties in one reporting segment. As of December 31, 2023, we owned the following real estate (dollars in thousands): Property 1225 Seventeenth Street (17th Street Plaza) 1250 H Street, NW 206 East 9th Street (Capitol Tower) Bridgepoint Square Total (1) State CO DC TX TX Number of Buildings Undepreciated Carrying Value Depreciated Carrying Value Annualized Rental Revenue(1) 1 1 1 5 8 $ 175,987 $ 110,816 $ 29,823 76,023 54,675 105,202 34,262 40,672 45,602 $ 411,887 $ 231,352 $ 7,032 8,588 12,743 58,186 Annualized rental revenue is annualized contractual rents from our tenants pursuant to leases which have commenced as of December 31, 2023, plus estimated recurring expense reimbursements; excludes lease value amortization, straight-line rent adjustments, abated (free) rent periods and parking revenue. We calculate annualized rental revenue by aggregating the recurring billings outlined above for the most recent month during the quarter reported, adding abated rent, and multiplying the sum by 12 to provide an estimation of near-term potentially-recurring revenues. Annualized rental revenue is a forward-looking non-GAAP measure. Annualized rental revenue cannot be reconciled to a comparable GAAP measure without unreasonable efforts, primarily due to the fact that it is calculated from the billings of tenants in the most recent month at the most recent rental rates during the quarter reported, whereas historical GAAP measures include billings from a potentially different group of tenants over multiple months at potentially different rental rates. As of December 31, 2023, we did not have any properties encumbered by mortgage notes. Item 3. Legal Proceedings. We are or may become a party to various legal proceedings. We are not currently involved in any litigation nor, to our knowledge, is any litigation threatened against us where the outcome would, in our judgment based on information currently available to us, have a material adverse effect on the Company. 21 Item 4. Mine Safety Disclosures. Not applicable. 22 PART II Item 5. Market for Registrant's Common Equity, Related Shareholder Matters and Issuer Purchases of Equity Securities. Our common shares are traded on the NYSE (symbol: EQC). As of February 5, 2024, there were 939 shareholders of record of our common shares. However, because many of our common shares are held by brokers and other institutions on behalf of shareholders, we believe that there are considerably more beneficial holders of our common shares than record holders. Distributions Under our governing documents and Maryland law, distributions to our shareholders are to be authorized and declared by our Board of Trustees. On February 13, 2023, our Board of Trustees declared a special, one-time cash distribution of $4.25 per common share/ unit to shareholders/unitholders of record on February 23, 2023. On March 9, 2023, we paid this distribution to such shareholders/unitholders in the aggregate amount of $468.3 million. On September 8, 2022, our Board of Trustees declared a special, one-time cash distribution of $1.00 per common share/ unit to shareholders/unitholders of record on September 29, 2022. On October 18, 2022, we paid this distribution to such shareholders/unitholders in the aggregate amount of $111.0 million. In February 2023, 2022 and 2021, the number of earned awards for recipients of the Company’s restricted stock units and market-based LTIP Units granted in January 2020, 2019, and 2018, respectively, was determined. Pursuant to the terms of such awards, we paid one-time catch-up cash distributions to these recipients in the aggregate amounts of $1.8 million, $1.5 million, and $6.0 million, in February 2023, 2022, and 2021, respectively, for distributions to common shareholders and unitholders declared by our Board of Trustees during such awards’ performance measurement period. The timing and amount of future distributions is determined at the discretion of our Board of Trustees and will depend upon various factors that our Board of Trustees deems relevant, including, but not limited to, our results of operations, our financial condition, debt and equity capital available to us, our expectations of our future capital requirements and operating performance, including our FFO, our Normalized FFO, and our cash available for distribution, restrictive covenants in our financial or other contractual arrangements (including those in our senior notes indenture), tax law requirements to qualify for taxation as and to remain a REIT, restrictions under Maryland law and our expected needs and availability of cash to pay our obligations and fund acquisitions. If our taxable income exceeds our net operating loss carryforwards, we will be required to make a distribution of at least 90% of our taxable income to maintain our qualification as a REIT. Whether we will make a distribution in 2024 and the timing of any such distribution remains uncertain. There can be no assurance that we will pay distributions in the future. Issuer Repurchases Common Share Repurchase Program On March 15, 2022, our Board of Trustees authorized the repurchase of up to $150.0 million of our outstanding common shares through June 30, 2023. On June 13, 2023, our Board of Trustees authorized the repurchase of up to $150.0 million of our outstanding common shares from July 1, 2023 through June 30, 2024. During the year ended December 31, 2023, we repurchased and retired 3,018,411 of our common shares at a weighted average price of $18.78 per share, for a total investment of $56.7 million. As of December 31, 2023, we had $93.3 million of remaining availability under our share repurchase program, which expires on June 30, 2024. Unregistered Sales of Securities There were no unregistered sales of equity securities during the year ended December 31, 2023. Performance Graph Notwithstanding anything to the contrary set forth in any of our filings under the Securities Act or the Exchange Act that might incorporate SEC filings, in whole or in part, the following performance graph will not be incorporated by reference into any such filings.

[Reserved] Not applicable. Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations. OBJECTIVE The objective of this section of this Annual Report on Form 10-K is to provide a discussion and analysis, from management’s perspective, of the material information necessary to assess our financial condition, results of operations, liquidity and cash flows for the year ended December 31, 2023. In addition, we have also included a discussion of any material events or uncertainties that we believe are reasonably likely to cause our 2023 financial results to not be indicative of future results. We also discuss potential business opportunities that we may pursue and the uncertainties associated with such pursuit. We have included an executive summary to identify what we believe are the more important items that affected our 2023 financial results, including both our business activities as well as events outside of our control. In addition to the executive summary, we encourage you to read the entire discussion in this section of our material financial and statistical data together with our consolidated financial statements and the accompanying notes that are included in Part IV, Item 15 of this Annual 24 Report on Form 10-K. The full discussion analyzes in detail our financial condition, results of operations, liquidity and cash flows, including comparisons of our 2023 and 2022 financial results. Discussions of 2021 items and year-to-year comparisons between 2022 and 2021 that are not included in this Annual Report on Form 10-K can be found in “Management's Discussion and Analysis of Financial Condition and Results of Operations” in Part II, Item 7 of our Annual Report on Form 10-K for the fiscal year ended December 31, 2022. OVERVIEW We are an internally managed and self-advised REIT primarily engaged in the ownership and operation of office properties in the United States. We were formed in 1986 under Maryland law. The Company operates as an UPREIT, conducting substantially all of its activities through the Operating Trust. As of December 31, 2023, the Company beneficially owned 99.79% of the outstanding OP Units. As of December 31, 2023, our portfolio consisted of four properties (eight buildings), with a combined 1.5 million square feet, and we had $2.2 billion of cash and cash equivalents. We use leasing and occupancy metrics to evaluate the performance of our properties. We believe these metrics provide useful information to investors because they reflect the leasing activity and vacant space at the properties and may facilitate comparisons of our leasing and occupancy metrics with other REITs and real estate companies. As of December 31, 2023, our overall portfolio was 81.2% leased. During the year ended December 31, 2023, we entered into leases for 214,000 square feet, including lease renewals for 157,000 square feet and new leases for 57,000 square feet. Leases entered into during the year ended December 31, 2023, including both lease renewals and new leases, had weighted average cash rental rates that were approximately 1.6% higher than prior rental rates for the same space and weighted average GAAP rental rates that were approximately 13.7% higher than prior rental rates for the same space. The change in GAAP rents is different than the change in cash rents due to differences in the amount of rent abatements, the magnitude and timing of contractual rent increases over the lease term, and the length of term for the newly executed leases compared to the prior leases. Percent change in GAAP and cash rents is a comparison of current rent, including estimated tenant expense reimbursements, if any, to the rent, including actual/projected tenant expense reimbursements, if any, last received for the same space on a GAAP and cash basis, respectively. Cash rent during the reporting period is calculated before deducting any initial period free rent. On February 13, 2023, our Board of Trustees declared a special, one-time cash distribution of $4.25 per common share/ unit to shareholders/unitholders of record on February 23, 2023. On March 9, 2023, we paid this distribution to such shareholders/unitholders in the aggregate amount of $468.3 million. We have engaged CBRE to provide property management services. We pay CBRE a property-by-property management fee and may engage CBRE from time-to-time to perform project management services, such as coordinating and overseeing the completion of tenant improvements and other capital projects at the properties. We reimburse CBRE for certain expenses incurred in the performance of its duties, including certain personnel and equipment costs. For the years ended December 31, 2023 and 2022, we incurred expenses of $3.2 million and $3.0 million, respectively, related to our property management agreement with CBRE, for property management fees, typically calculated as a percentage of the properties’ revenues, and salary and benefits reimbursements for property personnel, such as property managers, engineers and maintenance staff. As of December 31, 2023 and 2022, we had amounts payable pursuant to these services of $0.4 million and $0.4 million, respectively. We are focusing our efforts on capital allocation as we continue to evaluate investment opportunities. We are seeking to use the strength and liquidity of our balance sheet for investments in high-quality assets or businesses in a range of property types that offer a compelling risk-reward profile. We may also determine to sell, liquidate or otherwise exit our business if we believe doing so will maximize shareholder value. Our business has been and is continuing to be impacted by economic uncertainty and an overall slowdown in the office leasing market following the COVID-19 pandemic due to a variety of factors, including tenant uncertainty regarding office space needs given the evolving remote and hybrid working trends and other factors impacting the demand for office space. Many of our employees and the majority of our tenants’ employees are currently working at least in part remotely, with many businesses reassessing their long-term demand for office space. Overall, our business has experienced a significant reduction in leasing interest and activity as well as parking revenue when compared to pre-pandemic levels. As of December 31, 2023 and December 31, 2019, our comparable property portfolio was 81.2% and 91.5% leased, respectively. The duration of these business disruptions continues to be unknown at this time, and we currently are not able to estimate the full impact of the overall slowdown in the office leasing market on our business. 25 Property Operations Leased occupancy data for 2023 and 2022 are as follows (square feet in thousands): Total properties Total square feet Percent leased(2) All Properties As of December 31, Comparable Properties(1) As of December 31, 2023 2022 2023 2022 4 1,521 81.2 % 4 1,507 82.8 % 4 1,521 81.2 % 4 1,507 82.8 % (1) Based on properties owned continuously from January 1, 2022 through December 31, 2023. (2) Percent leased is the percent of space subject to signed leases. Percent leased is disclosed to quantify the ratio of leased square feet to rentable square feet and we believe it provides useful information as to the proportion of rentable square feet subject to a lease. The weighted average lease term based on square feet for leases entered into during the year ended December 31, 2023 was 5.2 years. Commitments made for leasing expenditures and concessions, such as tenant improvements and leasing commissions, for leases entered into during the year ended December 31, 2023 totaled $9.6 million, or $44.70 per square foot on average (approximately $8.60 per square foot per year of the lease term). As of December 31, 2023, approximately 17.1% of our leased square feet and 15.7% of our annualized rental revenue, determined as set forth below, are included in leases scheduled to expire through December 31, 2024. Renewal and new leases and rental rates at which available space may be relet in the future will depend on prevailing market conditions at the times these leases are negotiated. We believe that the in-place cash rents for leases expiring in 2024, that have not been backfilled, are approximately market. Lease expirations by year, as of December 31, 2023, are as follows (square feet and dollars in thousands): Year 2024 2025 2026 2027 2028 2029 2030 2031 2032 2033 Thereafter Number of Tenants Expiring(1) Leased Square Feet Expiring(2) % of Leased Square Feet Expiring(2) Cumulative % of Leased Square Feet Expiring(2) Annualized Rental Revenue Expiring(3) % of Annualized Rental Revenue Expiring 25 7 11 16 10 9 8 4 1 3 4 212 137 80 226 119 147 147 58 32 23 54 17.1 % 11.1 % 6.5 % 18.3 % 9.6 % 11.9 % 11.9 % 4.7 % 2.6 % 1.9 % 4.4 % 17.1 % $ 9,102 28.2 % 34.7 % 53.0 % 62.6 % 74.5 % 86.4 % 91.1 % 93.7 % 95.6 % 100.0 % 6,362 4,096 10,964 5,242 6,187 7,466 2,553 1,954 1,398 2,862 Cumulative % of Annualized Rental Revenue Expiring 15.7 % 26.6 % 33.6 % 52.5 % 61.5 % 72.1 % 84.9 % 89.3 % 92.7 % 95.1 % 15.7 % 10.9 % 7.0 % 18.9 % 9.0 % 10.6 % 12.8 % 4.4 % 3.4 % 2.4 % 4.9 % 100.0 % 98 1,235 100.0 % $ 58,186 100.0 % Weighted average remaining lease term (in years): 4.0 4.2 (1) Tenants with leases expiring in multiple years are counted in each year they expire. (2) Leased Square Feet as of December 31, 2023 includes space subject to leases that have commenced for revenue recognition purposes in accordance with GAAP, space being fitted out for occupancy pursuant to existing leases, and space which is leased but is not occupied or is being offered for sublease by tenants. The Leased Square Feet Expiring corresponds to the latest-expiring signed lease for a given suite. Thus, backfilled suites expire in the year stipulated by the new lease. (3) Annualized rental revenue is annualized contractual rents from our tenants pursuant to leases which have commenced as of December 31, 2023, plus estimated recurring expense reimbursements; excludes lease value amortization, straight-line rent adjustments, abated (free) rent periods and parking revenue. We calculate annualized rental revenue by aggregating the recurring billings outlined above for the most recent month during the quarter reported, adding abated rent, and multiplying the sum by 12 to provide an estimation of near-term potentially-recurring revenues. Annualized rental revenue is a 26 forward-looking non-GAAP measure. Annualized rental revenue cannot be reconciled to a comparable GAAP measure without unreasonable efforts, primarily due to the fact that it is calculated from the billings of tenants in the most recent month at the most recent rental rates during the quarter reported, whereas historical GAAP measures include billings from a potentially different group of tenants over multiple months at potentially different rental rates. The principal source of funds for our operations is rents from tenants at our properties. Rents are generally received from our tenants monthly in advance. As of December 31, 2023, tenants representing 2.5% or more of our total annualized rental revenue were as follows (square feet in thousands): Tenant 1. 2. Equinor Energy Services, Inc.

(2) Other properties consist of properties sold. (3) We define net operating income, or NOI, as income from our real estate including lease termination fees received from tenants less our property operating expenses. NOI excludes amortization of capitalized tenant improvement costs and leasing commissions and corporate level expenses. For a discussion of why we consider NOI to be an appropriate supplemental measure to net income as well as a reconciliation of NOI to net income, the most directly comparable financial measure under GAAP reported on our consolidated financial statements, please see the section entitled “Liquidity and Capital Resources - Property Net Operating Income (NOI).” Rental revenue. Rental revenue at the comparable properties decreased $3.6 million, or 6.1%, in the 2023 period, compared to the 2022 period, primarily due to the $1.9 million collection of a previously reserved receivable in 2022, a $0.9 million decrease in base rent due to a decrease in commenced occupancy, a $0.8 million decrease in real estate tax recoveries and a $0.5 million decrease in lease termination fees, partially offset by a $0.5 million increase in escalations. Excluding the collection of the previously reserved receivable, rental revenue at the comparable properties decreased $1.7 million, or 2.9%, in the 2023 period, compared to the 2022 period. Other revenue. Other revenue, which primarily includes parking revenue, increased $0.8 million, or 18.5% in the 2023 period, compared to the 2022 period primarily due to an increase in parking demand. Operating expenses. Operating expenses increased $3.3 million, or 13.6%, in the 2023 period, compared to the 2022 period, due to a $1.8 million real estate tax refund received at a sold property in 2022 and a $1.5 million increase in operating expenses at the comparable properties. Operating expenses increased $1.5 million, or 5.9%, at the comparable properties in the 2023 period, compared to the 2022 period, primarily due to a $1.1 million increase in pre-leasing demolition costs, a $0.2 million increase in maintenance and repairs, a $0.2 million increase in utilities expense, a $0.2 million increase in salary expense, a $0.2 million increase in HVAC expense, a $0.1 million increase in security expense and a $0.1 million increase in parking garage expense, partially offset by a $0.9 million decrease in real estate tax expense. General and administrative. General and administrative expenses increased $6.6 million, or 21.7% in the 2023 period, compared to the 2022 period, primarily due to $6.0 million of compensation expenses related to the passing of our former chairman in the 2023 period, a $1.1 million increase in bonus expense, a $0.5 million increase in payroll expense and a $0.3 million increase in payroll taxes primarily due to refunds received in 2022, partially offset by a $0.7 million decrease in share- 28 based compensation expenses and a $0.6 million decrease in compensation expenses related to severance. Excluding the $6.0 million of compensation expense related to the passing of our former chairman in the 2023 period, general and administrative expenses increased $0.6 million, or 2.1%, in the 2023 period, compared to the 2022 period. Interest and other income, net. Interest and other income, net increased $67.7 million, or 144.3%, in the 2023 period, compared to the 2022 period, primarily due to more interest received from higher average interest rates, partially offset by lower average cash balances. Gain on sale of properties, net. We did not have any gain on sale of properties, net in the 2023 period. Gain on sale of properties, net of $0.1 million in the 2022 period relates to adjustments to prior period sales. Income tax expense. Income tax expense increased $1.4 million, or 311.9%, in the 2023 period, compared to the 2022 period, primarily due to an increase in federal income taxes at our taxable REIT subsidiary. Net income attributable to noncontrolling interest. From 2017 through 2022, we granted LTIP Units to certain of our trustees and employees. Net income attributable to noncontrolling interest of $0.3 million in the 2023 period and $0.1 million in the 2022 period, relates to the allocation of income to the LTIP/OP Unit holders. LIQUIDITY AND CAPITAL RESOURCES Our Operating Liquidity and Resources As of December 31, 2023, we had $2.2 billion of cash and cash equivalents. We expect to use our cash balances, cash flow from our operations and proceeds of any future property sales to fund our operations, make distributions, repurchase our common shares, make investments in properties or businesses, fund tenant improvements and leasing costs and for other general business purposes. We believe our cash balances and the cash flow from our operations will be sufficient to fund our ordinary course activities. Our future cash flows from operating activities will depend on our ability to collect rent from our current tenants under their leases. Our ability to collect rent and generate parking revenue in the near term may continue to be adversely impacted by the market disruption caused by economic uncertainty and an overall slowdown in the office leasing market following the COVID-19 pandemic, including remote and hybrid working trends and other factors impacting the demand for office space. We cannot predict the ultimate impact of the overall slowdown in the office leasing market on our results of operations. Our future cash flows from operating activities will also depend upon our: • • • ability to maintain or improve the occupancy of, and the rental rates at, our properties; ability to control operating and financing expense increases at our properties; and ability to purchase additional properties, which produce rents, less property operating expenses, in excess of our costs of acquisition capital. In addition, our future cash flows will also depend in part on interest income earned on our invested cash balances. Volatility in energy costs and real estate taxes may cause our future operating expenses to fluctuate; however, the impact of these fluctuations is expected to be partially offset by the pass through of operating expenses to our tenants pursuant to lease terms, although there can be no assurance that we will be able to successfully offset these expenses or that doing so would not negatively impact our competitive position or business. Net cash flows provided by (used in) operating, investing and financing activities were $122.3 million, $(5.7) million and $(538.3) million, respectively, for the year ended December 31, 2023, and $65.0 million, $(3.5) million and $(280.3) million, respectively, for the year ended December 31, 2022. Changes in these three categories of our cash flows between 2023 and 2022 are primarily related to an increase in interest income as a result of higher average interest rates partially offset by lower average balances in 2023, repurchase of our common shares and distributions to common shareholders. 29 Our Investment and Financing Liquidity and Resources On February 13, 2023, our Board of Trustees declared a special, one-time cash distribution of $4.25 per common share/ unit to shareholders/unitholders of record on February 23, 2023. On March 9, 2023, we paid this distribution to such shareholders/unitholders in the aggregate amount of $468.3 million. During the year ended December 31, 2023, we paid an aggregate of $8.0 million of distributions on our series D preferred shares. On January 16, 2024, our Board of Trustees declared a dividend of $0.40625 per series D preferred share, which will be paid on February 15, 2024 to shareholders of record on January 31, 2024. On June 13, 2023, our Board of Trustees authorized the repurchase of up to $150.0 million of our outstanding common shares under our share repurchase program from July 1, 2023 through June 30, 2024. During the year ended December 31, 2023, we repurchased and retired 3,018,411 of our common shares at a weighted average price of $18.78 per share, for a total investment of $56.7 million. As of December 31, 2023, we had $93.3 million of remaining availability under our share repurchase program, which expires on June 30, 2024. We may utilize various types of financings, including debt or equity, to fund future investments and to pay any debt we may incur and other obligations as they become due. Although we are not currently rated by the debt rating agencies, the completion and the costs of any future debt transactions will depend primarily upon market conditions and our credit ratings at such time, if any. We have no control over market conditions. Any credit ratings will depend upon evaluations by credit rating agencies of our business practices and plans and, in particular, whether we appear to have the ability to maintain our earnings, to space any debt maturities and to balance our use of debt and equity capital so that our financial performance and leverage ratios afford us flexibility to withstand any reasonably foreseeable adverse changes. We intend to conduct our business activities in a manner which will continue to afford us reasonable access to capital for investment and financing activities. However, there can be no assurance regarding our ability to complete any debt or equity offerings or that our cost of any future public or private financings will not increase. During the years ended December 31, 2023, 2022 and 2021 amounts capitalized at our properties for tenant improvements, leasing costs and building improvements were as follows (amounts in thousands): Tenant improvements(1) Leasing costs(2) Building improvements(3) Years Ended December 31, 2023 2022 2021 $ 3,977 $ 3,405 $ 2,631 3,661 2,899 597 5,442 1,498 884 (1) Tenant improvements include capital expenditures to improve tenants’ spaces. (2) Leasing costs include leasing commissions and related legal expenses. (3) Building improvements generally include expenditures to replace obsolete building components and expenditures that extend the useful life of existing assets. Tenant-funded capital expenditures are excluded. During the year ended December 31, 2023, commitments made for expenditures in connection with leasing space at our properties were as follows (dollar and square foot measures in thousands): Square feet leased during the period Tenant improvements and leasing commissions Tenant improvements and leasing commissions per square foot Weighted average lease term by square foot (years)(1) New Leases Renewals Total 57 157 214 $ $ 4,198 $ 5,363 $ 9,561 73.65 $ 34.16 $ 44.70 5.7 5.0 5.2 Tenant improvements and leasing commissions per square foot per year of lease term $ 12.92 $ 6.83 $ 8.60 (1) For renewal lease terms, if the existing rents of an original lease term are modified, the new term starts at the rent modification date. Weighted average lease term generally excludes renewal options. Committed but unspent tenant related obligations are leasing commissions and tenant improvements. Based on existing leases as of December 31, 2023, committed but unspent tenant related obligations were $13.1 million. 30 NON-GAAP MEASURES Funds from Operations (FFO) and Normalized FFO We compute FFO in accordance with standards established by the National Association of Real Estate Investment Trusts, or Nareit. Nareit defines FFO as net income (loss), calculated in accordance with GAAP, excluding real estate depreciation and amortization, gains (or losses) from sales of depreciable property, impairment of depreciable real estate, and our portion of these items related to equity investees and noncontrolling interests. Our calculation of Normalized FFO differs from Nareit’s definition of FFO because we exclude certain items that we view as nonrecurring or impacting comparability from period to period. We consider FFO and Normalized FFO to be appropriate measures of operating performance for a REIT, along with net income, net income attributable to Equity Commonwealth common shareholders and cash flow from operating activities. We believe that FFO and Normalized FFO provide useful information to investors because by excluding the effects of certain historical amounts, such as depreciation expense, FFO and Normalized FFO may facilitate a comparison of our operating performance between periods and with other REITs. FFO and Normalized FFO do not represent cash generated by operating activities in accordance with GAAP and should not be considered as alternatives to net income (loss), net income (loss) attributable to Equity Commonwealth common shareholders or cash flow from operating activities, determined in accordance with GAAP, or as indicators of our financial performance or liquidity, nor are these measures necessarily indicative of sufficient cash flow to fund all of our needs. These measures should be considered in conjunction with net income (loss), net income (loss) attributable to Equity Commonwealth common shareholders and cash flow from operating activities as presented in our consolidated statements of operations and consolidated statements of cash flows. Other REITs and real estate companies may calculate FFO and Normalized FFO differently than we do. The following table provides a reconciliation of net income (loss) to FFO attributable to Equity Commonwealth common shareholders and unitholders and a reconciliation to Normalized FFO attributable to Equity Commonwealth common shareholders and unitholders (in thousands): Reconciliation to FFO: Net income (loss) Real estate depreciation and amortization Gain on sale of properties, net FFO attributable to Equity Commonwealth Preferred distributions Years Ended December 31, 2023 2022 2021 $ 91,445 $ 37,357 $ (16,429) 17,409 17,652 17,593 — (97) — 108,854 54,912 1,164 (7,988) (7,988) (7,988) FFO attributable to Equity Commonwealth common shareholders and unitholders $ 100,866 $ 46,924 $ (6,824) Reconciliation to Normalized FFO: FFO attributable to Equity Commonwealth common shareholders and unitholders $ 100,866 $ 46,924 $ (6,824) Straight-line rent adjustments Former chairman accelerated compensation expense Sold property expense included in interest and other income, net Executive severance expense (93) 5,957 — — 238 (1,407) — — — — (225) 7,107 Normalized FFO attributable to Equity Commonwealth common shareholders and unitholders $ 106,730 $ 47,162 $ (1,349) Property Net Operating Income (NOI) We use another non-GAAP measure, property net operating income, or NOI, to evaluate the performance of our properties. We define NOI as income from our real estate including lease termination fees received from tenants less our property operating expenses. NOI excludes amortization of capitalized tenant improvement costs and leasing commissions and corporate level expenses. The following table includes the reconciliation of NOI to net income, the most directly comparable financial measure under GAAP reported in our consolidated financial statements. We consider NOI to be an appropriate supplemental measure to net income (loss) because it may help to understand the operations of our properties. We use NOI internally to evaluate property level performance, and we believe that NOI provides useful information to investors regarding our results of 31 operations because it reflects only those income and expense items that are incurred at the property level and may facilitate comparisons of our operating performance between periods and with other REITs. NOI does not represent cash generated by operating activities in accordance with GAAP and should not be considered as an alternative to net income, net income attributable to Equity Commonwealth common shareholders or cash flow from operating activities, determined in accordance with GAAP, or as an indicator of our financial performance or liquidity, nor is this measure necessarily indicative of sufficient cash flow to fund all of our needs. This measure should be considered in conjunction with net income (loss), net income (loss) attributable to Equity Commonwealth common shareholders and cash flow from operating activities as presented in our consolidated statements of operations and consolidated statements of cash flows. Other REITs and real estate companies may calculate NOI differently than we do. A reconciliation of NOI to net income (loss) for the years ended December 31, 2023, 2022 and 2021, is as follows (in thousands): Rental revenue Other revenue Operating expenses NOI NOI Depreciation and amortization General and administrative Interest and other income, net Gain on sale of properties, net Income (loss) before income taxes Income tax expense Net income (loss) CRITICAL ACCOUNTING POLICIES Year Ended December 31, 2023 2022 2021 $ 55,336 $ 58,763 $ 54,927 $ $ 5,188 4,377 3,075 (27,462) (24,184) (25,893) 33,062 $ 38,956 $ 32,109 33,062 $ 38,956 $ 32,109 (17,444) (36,974) 114,667 — 93,311 (1,866) (17,810) (30,378) 46,945 97 37,810 (453) (17,774) (37,444) 6,800 — (16,309) (120) $ 91,445 $ 37,357 $ (16,429) Our critical accounting policies are those that will have the most impact on the reporting of our financial condition and results of operations and those requiring significant judgments and estimates. We believe that our judgments and estimates are consistently applied and produce financial information that fairly presents our results of operations. Our most critical accounting policies involve our investments in real property. These policies affect our assessment of the carrying values and impairments of long lived assets. We periodically evaluate our properties for possible impairments. Impairment indicators may include declining tenant occupancy, lack of progress releasing vacant space, tenant bankruptcies, low long-term prospects for improvement in property performance, weak or declining tenant profitability, cash flow or liquidity, our decision to dispose of an asset before the end of its estimated useful life and legislative, market or industry changes that could permanently reduce the value of a property. If indicators of impairment are present, we evaluate the carrying value of the related property by comparing it to the expected future undiscounted cash flows to be generated from that property over our anticipated hold period. If the sum of these expected future cash flows is less than the carrying value, we reduce the net carrying value of the property to its estimated fair value. This analysis requires us to judge whether indicators of impairment exist and to estimate likely future cash flows. Projections of expected future operating cash flows require that we estimate future market rental revenue amounts subsequent to the expiration of current lease agreements, future property operating expenses, the number of months it takes to re-lease the property, and the number of years the property is held for investment, among other factors. The subjectivity of assumptions used in the future cash flow analysis, including discount rates, could result in an incorrect assessment of the property’s fair value and could result in the misstatement of the carrying value of our real estate assets and net income (loss). These policies involve significant judgments made based upon experience, including judgments about current valuations, ultimate realizable value, estimated useful lives, salvage or residual value, the ability and willingness of our tenants to perform their obligations to us, current and future economic conditions and competitive factors in the markets in which our properties are located. Competition, economic conditions and other factors may cause occupancy declines in the future. In the future, we may need to revise our carrying value assessments to incorporate information which is not now known, and such revisions could increase or decrease our depreciation expense related to properties we own or decrease the carrying values of our assets. 32 RELATED PERSON TRANSACTIONS For information about our related person transactions, see Note 12 of the Notes to Consolidated Financial Statements included in Part IV, Item 15 of this Annual Report on Form 10-K, which is incorporated herein by reference.

Changes in Internal Control Over Financial Reporting There have been no changes in our internal control over financial reporting during the quarter ended December 31, 2023, that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting. Management Report on Assessment of Internal Control Over Financial Reporting We are responsible for establishing and maintaining adequate internal control over financial reporting. Our internal control system is designed to provide reasonable assurance to our management and Board of Trustees regarding the preparation and fair presentation of published financial statements. All internal control systems, no matter how well designed, have inherent limitations. Therefore, even those systems determined to be effective can provide only reasonable assurance with respect to financial statement preparation and presentation. Our management assessed the effectiveness of our internal control over financial reporting as of December 31, 2023. In making this assessment, it used the criteria set forth by the Committee of Sponsoring Organizations of the Treadway Commission (2013 framework) in Internal Control—Integrated Framework. Based on our assessment, we believe that, as of December 31, 2023 our internal control over financial reporting is effective. Our internal control over financial reporting has been audited as of December 31, 2023 by Ernst & Young LLP, an independent registered public accounting firm, as stated in their report which is included herein on page F-2. Item 9B. Other Information. During the three months ended December 31, 2023, none of our trustees or officers adopted or terminated a “Rule 10b5-1 trading arrangement” or a “non-Rule 10b5-1 trading arrangement” (as such terms are defined under Item 408 of Regulation S- K).

In our opinion, the consolidated financial statements present fairly, in all material respects, the financial position of the Company at December 31, 2023 and 2022, and the results of its operations and its cash flows for each of the three years in the period ended December 31, 2023, 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, 2023, 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 13, 2024 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 Matters Critical audit matters are matters arising from the current period audit of the financial statements that were communicated or required to be communicated to the audit committee and that: (1) relate to accounts or disclosures that are material to the financial statements and (2) involved our especially challenging, subjective or complex judgments. We determined that there are no critical audit matters. /s/ Ernst & Young LLP We have served as the Company’s auditor since 1986. Chicago, Illinois February 13, 2024 F-1 REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM To the Shareholders and the Board of Trustees of Equity Commonwealth Opinion on Internal Control Over Financial Reporting We have audited Equity Commonwealth’s internal control over financial reporting as of December 31, 2023, 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, Equity Commonwealth (the Company) maintained, in all material respects, effective internal control over financial reporting as of December 31, 2023, 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 consolidated balance sheets of Equity Commonwealth as of December 31, 2023 and 2022, the related consolidated statements of operations, equity and cash flows for each of the three years in the period ended December 31, 2023, and the related notes and financial statement schedule listed at Item 15(a) and our report dated February 13, 2024 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 Report on Assessment of 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 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 Chicago, Illinois February 13, 2024 F-2 EQUITY COMMONWEALTH CONSOLIDATED BALANCE SHEETS (amounts in thousands, except share data) ASSETS Real estate properties: Land Buildings and improvements Accumulated depreciation Cash and cash equivalents Rents receivable Other assets, net Total assets LIABILITIES AND EQUITY Accounts payable, accrued expenses and other Rent collected in advance Distributions payable Total liabilities Commitments and contingencies Shareholders’ equity: December 31, 2023 2022 $ 44,060 $ 44,060 367,827 411,887 364,063 408,123 (180,535) (169,530) 231,352 238,593 2,160,535 2,582,222 15,737 17,417 16,009 18,061 $ 2,425,041 $ 2,854,885 $ 27,298 $ 25,935 1,990 5,640 34,928 2,355 2,863 31,153 Preferred shares of beneficial interest, $0.01 par value: 50,000,000 shares authorized; Series D preferred shares; 6.50% cumulative convertible; 4,915,196 shares issued and outstanding, aggregate liquidation preference of $122,880 119,263 119,263 Common shares of beneficial interest, $0.01 par value: 350,000,000 shares authorized; 106,847,438 and 109,428,252 shares issued and outstanding, respectively Additional paid in capital Cumulative net income Cumulative common distributions Cumulative preferred distributions Total shareholders’ equity Noncontrolling interest Total equity Total liabilities and equity 1,068 3,935,873 3,926,979 1,094 3,979,566 3,835,815 (4,864,440) (4,393,522) (733,676) (725,688) 2,385,067 5,046 2,390,113 2,816,528 7,204 2,823,732 $ 2,425,041 $ 2,854,885 See accompanying notes.

Organization Equity Commonwealth, or the Company, is a real estate investment trust, or REIT, formed in 1986 under the laws of the State of Maryland. Our business is primarily the ownership and operation of office properties in the United States. The Company operates in an umbrella partnership real estate investment trust, or UPREIT, and conducts substantially all of its activities through EQC Operating Trust, a Maryland real estate investment trust, or the Operating Trust. The Company beneficially owned, 99.79% of the outstanding shares of beneficial interest, designated as units, in the Operating Trust, or OP Units, as of December 31, 2023, and the Company is the sole trustee of the Operating Trust. As the sole trustee, the Company generally has the power under the declaration of trust of the Operating Trust to manage and conduct the business of the Operating Trust, subject to certain limited approval and voting rights of other holders of OP Units. As of December 31, 2023, our portfolio consisted of four properties (eight buildings), with a combined 1.5 million square feet, and we had $2.2 billion of cash and cash equivalents. All numbers of properties, numbers of buildings and square feet are unaudited. On May 4, 2021, we entered into a merger agreement to acquire Monmouth Real Estate Investment Corporation (NYSE: MNR), or Monmouth, a publicly-traded industrial REIT. On August 31, 2021, following Monmouth’s failure to obtain shareholder approval of the merger, in accordance with the terms of the merger agreement, we terminated the merger agreement and were reimbursed $10.0 million by Monmouth for our out-of-pocket expenses. Total transaction costs net of the reimbursement resulted in $0.1 million of general and administrative expense recorded in the year ended December 31, 2021. Note 2. Summary of Significant Accounting Policies Basis of Presentation. The consolidated financial statements include our investments in 100% owned subsidiaries and majority owned subsidiaries that are controlled by us. References to we, us, our and the Company, refer to Equity Commonwealth and its consolidated subsidiaries as of December 31, 2023, unless the context indicates otherwise. All intercompany transactions and balances have been eliminated. Dollar amounts presented may be approximate. Share amounts are presented in whole numbers, except where noted. Real Estate Properties. We record real estate properties at cost. We depreciate real estate investments on a straight-line basis over estimated useful lives of up to 40 years for buildings and improvements, and up to 12 years for personal property. Each time we enter into a new lease, or materially modify an existing lease, we evaluate its classification as either a finance or operating lease. The classification of a lease as finance or operating affects the carrying value of a property, as well as our recognition of rental payments as revenue. These evaluations require us to make estimates of, among other things, the remaining useful life and fair market value of a leased property, appropriate discount rates and future cash flows. We allocate the consideration paid for our properties among land, buildings and improvements and, for properties that qualify as acquired businesses under the Business Combinations Topic of the Financial Accounting Standards Board, or FASB, Accounting Standards Codification, or ASC, to identified intangible assets and liabilities, consisting of the value of above market and below market leases, the value of acquired in place leases and the value of tenant relationships. Purchase price allocations and the determination of useful lives are based on our estimates and, under some circumstances, studies from independent real estate appraisal firms to provide market information and evaluations that are relevant to our purchase price allocations and determinations of useful lives; however, we are ultimately responsible for the purchase price allocations and determination of useful lives. We allocate the consideration to land, buildings and improvements based on a determination of the fair values of these assets assuming the property is vacant. We determine the fair value of a property using methods that we believe are similar to those used by independent appraisers. Purchase price allocations for above market and below market leases are based on the estimated present value (using an interest rate which reflects our assessment of the risks associated with the leases acquired) of the difference between (1) the contractual amounts to be paid pursuant to the acquired in place leases and (2) our estimate of fair market lease rates for the corresponding leases, measured over a period equal to the remaining non-cancelable terms of the respective leases. Purchase price allocations to acquired in place leases and tenant relationships are determined as the excess of (1) the purchase price paid for a property after adjusting existing in place leases to estimated market rental rates over (2) the estimated fair value of the property as if vacant. We aggregate this value between acquired in place lease values and tenant relationships based on our evaluation of the specific characteristics of each tenant's lease; however, the value of tenant F-8 EQUITY COMMONWEALTH NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (Continued) relationships has not been separated from acquired in place lease value for our properties because we believe such value and related amortization expense is immaterial for acquisitions reflected in our historical financial statements. We consider certain factors in performing these analyses including estimates of carrying costs during the expected lease up periods, including real estate taxes, insurance and other operating income and expenses and costs to execute similar leases in current market conditions, such as leasing commissions, legal and other related costs. If we believe the value of tenant relationships is material in the future, those amounts will be separately allocated and amortized over the estimated lives of the relationships. We recognize the excess, if any, of the consideration paid over amounts allocated to land, buildings and improvements and identified intangible assets and liabilities as goodwill and we recognize gains if amounts allocated exceed the consideration paid. We amortize capitalized above market lease values as a reduction to rental income over the remaining terms of the respective leases. We amortize capitalized below market lease values as an increase to rental income over the remaining terms of the respective leases. We amortize the value of acquired in place leases exclusive of the value of above market and below market acquired in place leases to expense over the remaining terms of the respective leases. If a lease is terminated prior to its stated expiration, the unamortized lease intangibles relating to that lease is written off. We review our properties for impairment quarterly, or whenever events or changes in circumstances indicate that their carrying amounts may not be recoverable. Impairment indicators may include our decision to dispose of an asset before the end of its estimated useful life, declining tenant occupancy, lack of progress releasing vacant space, tenant bankruptcies, low long- term prospects for improvement in property performance, weak or declining tenant profitability, and cash flow or liquidity. When indicators of potential impairment are present that suggest that the carrying amounts of real estate assets may not be recoverable, we assess the recoverability of these assets by determining whether the respective carrying values will be recovered through the estimated undiscounted future operating cash flows expected from the use of the assets and their eventual disposition. The determination of undiscounted cash flow includes consideration of many factors including income to be earned from the investment over our anticipated hold period, holding costs (exclusive of interest), estimated selling prices, and prevailing economic and market conditions. In the event that such expected undiscounted future cash flows do not exceed the carrying values, we estimate the fair value of the assets and record an impairment charge equal to the amount by which the carrying value exceeds the estimated fair value. Estimated fair values are calculated based on the following information, (i) recent third party estimates of market value, (ii) market prices for comparable properties, or (iii) the present value of future cash flows. During the years ended December 31, 2023, 2022 and 2021 we did not record any loss on asset impairment. When we classify properties as held for sale, we discontinue the recording of depreciation expense and estimate their fair value less costs to sell. If we determine that the carrying value for these properties exceed their estimated fair value less costs to sell, we record a loss on asset impairment. As of December 31, 2023 and 2022, we did not have any properties classified as held for sale. Certain of our real estate assets contain hazardous substances, including asbestos. We believe any asbestos in our buildings is contained in accordance with current regulations. If we remove the asbestos or renovate or demolish these properties, certain environmental regulations govern the manner in which the asbestos must be handled and removed. We do not believe that there are other environmental conditions or issues at any of our properties that have had or will have a material adverse effect on us. However, no assurances can be given that conditions or issues are not present at our properties or that costs we may be required to incur in the future to remediate contamination or comply with environmental, health and safety laws will not have a material adverse effect on our business or financial condition. As of December 31, 2023 and 2022, we did not have any accrued environmental remediation costs. Cash and Cash Equivalents. Our cash and cash equivalents consist of cash maintained in time deposits, depository accounts and money market accounts. We regularly monitor the credit ratings of the financial institutions holding our deposits to minimize our exposure to credit risk. Throughout the year, we have cash balances in excess of federally insured limits deposited with various financial institutions. We do not believe we are exposed to any significant credit risk on cash and cash equivalents. Other Assets, Net. Other assets consist principally of deferred leasing costs, capitalized lease incentives and prepaid property operating expenses. Deferred leasing costs are amortized on a straight-line basis over the terms of the respective leases. Capitalized lease incentives are amortized on a straight-line basis against rental income over the terms of the respective leases. Revenue Recognition. Rental revenue from operating leases, which includes rent concessions (including free rent and other lease incentives) and scheduled increases in rental rates during the lease term, represents the lease component and is F-9 EQUITY COMMONWEALTH NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (Continued) recognized on a straight-line basis over the life of the lease agreements. We defer the recognition of contingent rental income, such as percentage rents, until the specific targets that trigger the contingent rental income are achieved. Rental revenue also includes non-lease components such as property level operating expenses reimbursed by our tenants and other incidental revenues, which are recorded as expenses are incurred. We concluded that the timing and pattern of transfer for non-lease components and the associated lease component are the same. We determined that the predominant component was the lease component and we have elected to account for and present the lease component and non-lease component of our leases as a single component in Rental revenue in our consolidated statements of operations in accordance with FASB Topic 842. Lessee Lease Classification. We classify leases as either finance or operating in accordance with FASB Topic 842, Leases. This classification determines whether the related expense is recognized based on an effective interest method for finance leases or on a straight-line basis over its life for operating leases. Additionally, lessees are required to record a right-of- use asset and lease liability for all leases with a term greater than 12 months. We have made an accounting policy election as permitted under ASC 842 to forgo recognition of a right-of-use asset and lease liability for short-term leases of less than 12 months. Earnings Per Common Share. Earnings per common share, or EPS, is computed using the weighted average number of common shares outstanding during the period. Diluted EPS reflects the potential dilution that could occur if our series D convertible preferred shares, our restricted share units, or RSUs, or beneficial interests in the Operating Trust, or LTIP Units, were converted into our common shares, which could result in a lower EPS amount. The effect of our series D convertible preferred shares on net income attributable to common shareholders is anti-dilutive for the years ended December 31, 2023, 2022 and 2021. Reclassifications. Reclassifications have been made to the prior years' financial statements and notes to conform to the current year's presentation. Legal Matters. We are or may become a party to various legal proceedings. We are not currently involved in any litigation nor, to our knowledge, is any litigation threatened against us where the outcome would, in our judgment based on information currently available to us, have a material adverse effect on the Company. Income Taxes. We are a REIT under the Internal Revenue Code of 1986, as amended, and are generally not subject to federal and state income taxes provided we distribute our taxable income to our shareholders and meet other requirements for qualifying as a REIT. We are also subject to certain state and local taxes without regard to our REIT status. The Income Taxes Topic of the FASB ASC prescribes how we should recognize, measure and present in our financial statements uncertain tax positions that have been taken or are expected to be taken in a tax return. Deferred tax assets are recognized to the extent that it is “more likely than not” that a particular tax position will be sustained upon examination or audit. To the extent the “more likely than not” standard has been satisfied, the benefit associated with a tax position is measured as the largest amount that has a greater than 50% likelihood of being realized upon settlement. We classify interest and penalties related to uncertain tax positions, if any, in our financial statements as a component of general and administrative expense. Use of Estimates. Preparation of these financial statements in conformity with U.S. generally accepted accounting principles, or GAAP, requires us to make estimates and assumptions that may affect the amounts reported in these financial statements and related notes. The actual results could differ from these estimates. New Accounting Pronouncements. In November 2023, the FASB issued Accounting Standards Update, or ASU, 2023-07, Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures, which improves the disclosures about a public entity's reportable segments and addresses requests from investors for additional, more detailed information about a reportable segment's expenses. This update is effective for fiscal years beginning after December 15, 2023, and interim periods within fiscal years beginning after December 15, 2024. Early adoption is permitted. We do not expect the adoption of ASU 2023-07 to have a material impact on our consolidated financial statements. In December 2023, the FASB issued ASU 2023-09, Income Taxes (Topic 740): Improvements to Income Tax Disclosures, which enhances the transparency and decision usefulness of income tax disclosures. This update is effective for annual periods beginning after December 15, 2024. Early adoption is permitted for annual financial statements that have not yet been issued or made available for issuance. We do not expect the adoption of ASU 2023-09 to have a material impact on our consolidated financial statements. F-10 EQUITY COMMONWEALTH NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (Continued) Note 3. Real Estate Properties Acquisitions and Expenditures We did not make any acquisitions during the years ended December 31, 2023, 2022 or 2021. During the years ended December 31, 2023, 2022, and 2021, we made improvements, excluding tenant-funded improvements, to our properties totaling $7.6 million, $4.0 million and $6.3 million, respectively. We committed $9.6 million for expenditures related to 0.2 million square feet of leases executed during 2023. Committed but unspent tenant related obligations are leasing commissions and tenant improvements. Based on existing leases as of December 31, 2023, committed but unspent tenant related obligations were $13.1 million. Property Dispositions: We did not sell any properties during the years ended December 31, 2023, 2022 or 2021. Lease Payments Our real estate properties are generally leased on gross lease and modified gross lease bases pursuant to non-cancelable, fixed term operating leases expiring between 2024 and 2035.

Common Share Repurchases: On August 24, 2015, our Board of Trustees approved a common share repurchase program. On March 1, 2021, our Board of Trustees authorized the repurchase of up to $150.0 million of our outstanding common shares through June 30, 2022, and on December 14, 2021, our Board of Trustees authorized the repurchase of up to an additional $150.0 million of our outstanding common shares through December 31, 2022. On March 15, 2022, our Board of Trustees authorized the repurchase of up to $150.0 million of our outstanding common shares through June 30, 2023. On June 13, 2023, our Board of Trustees authorized the repurchase of up to $150.0 million of our outstanding common shares from July 1, 2023 through June 30, 2024. During the year ended December 31, 2023, we repurchased and retired 3,018,411 of our common shares at a weighted average price of $18.78 per share, for a total investment of $56.7 million. During the year ended December 31, 2022, we repurchased and retired 6,110,646 of our common shares at a weighted average dividend adjusted price of $24.64 per share, for a total investment of $155.5 million. During the year ended December 31, 2021, we repurchased and retired 6,735,810 of our common shares at a weighted average price of $25.85 per share, for a total investment of $174.1 million. The share repurchases in 2022 discussed in this paragraph were completed prior to the special, one-time cash distributions in that year, which was in the amount of $1.00 per common share/unit paid on October 18, 2022. As of December 31, 2023, we had $93.3 million of remaining availability under our share repurchase program, which expires on June 30, 2024. F-12 EQUITY COMMONWEALTH NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (Continued) During the years ended December 31, 2023, 2022 and 2021, certain of our employees and former employees surrendered 134,193, 160,506 and 245,560 common shares owned by them, respectively, to satisfy their statutory tax withholding obligations in connection with the vesting of such common shares pursuant to our equity compensation plans. Common Share and Unit Distributions: On February 13, 2023, our Board of Trustees declared a special, one-time cash distribution of $4.25 per common share/ unit to shareholders/unitholders of record on February 23, 2023. On March 9, 2023, we paid this distribution to such shareholders/unitholders in the aggregate amount of $468.3 million. On September 8, 2022, our Board of Trustees declared a special, one-time cash distribution of $1.00 per common share/ unit to shareholders/unitholders of record on September 29, 2022. On October 18, 2022, we paid this distribution to such shareholders/unitholders in the aggregate amount of $111.0 million. In February 2023, 2022 and 2021, the number of earned awards for recipients of the Company’s restricted stock units and market-based LTIP Units granted in January 2020, 2019, and 2018, respectively, was determined. Pursuant to the terms of such awards, we paid one-time catch-up cash distributions to these recipients in the aggregate amounts of $1.8 million, $1.5 million, and $6.0 million, in February 2023, 2022, and 2021, respectively, for distributions to common shareholders and unitholders declared by our Board of Trustees during such awards’ performance measurement period. The following characterizes distributions paid per common share for the years ended December 31, 2023, 2022, and 2021: Ordinary income Return of capital Capital gain Unrecaptured Section 1250 gain Series D Preferred Shares: Year Ended December 31, 2023 2022 2021 63.91 % 36.09 % — % — % 99.07 % 0.93 % — % — % 100.00 % 100.00 % — % — % — % — % — % Each of our 4,915,196 series D cumulative convertible preferred shares accrue dividends of $1.625, or 6.50% per annum of the liquidation amount, payable in equal quarterly payments. Our series D preferred shares are convertible, at the holder’s option, into our common shares at a conversion rate of 0.8204 common shares per series D preferred share, which is equivalent to a conversion price of $30.47 per common share, or 4,032,427 additional common shares at December 31, 2023. The conversion rate changed from 0.6846 to 0.8204 common shares per series D preferred share effective February 24, 2023 as a result of the common share distribution declared by our Board of Trustees in 2023. The conversion rate changed from 0.6585 to 0.6846 common shares per series D preferred share effective September 30, 2022 as a result of the common share distribution declared by our Board of Trustees in 2022. If our common shares trade at or above the then applicable conversion price, we may, at our option, convert some or all of the series D preferred shares into common shares at the then applicable conversion rate. If a fundamental change occurs, which generally will be deemed to occur upon a change in control or a termination of trading of our common shares (or other equity securities into which our series D preferred shares are then convertible), holders of our series D preferred shares will have a special right to convert their series D preferred shares into a number of our common shares per $25.00 liquidation preference, plus accrued and unpaid distributions, divided by 98% of the average closing market price of our common shares for a specified period before such event is effective, unless we exercise our right to repurchase these series D preferred shares for cash, at a purchase price equal to 100% of their liquidation preference, plus accrued and unpaid distributions. The issuance of a large number of common shares as a result of the exercise of this conversion right after a fundamental change may have a dilutive effect on net income attributable to Equity Commonwealth common shareholders per share for future periods. As of December 31, 2023, we had 4,915,196 outstanding series D preferred shares that were convertible into 4,032,427 of our common shares. F-13 EQUITY COMMONWEALTH NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (Continued) Preferred Share Distributions: Under our governing documents and Maryland law, distributions to our shareholders are to be authorized and declared by our Board of Trustees. In 2023, our Board of Trustees declared distributions on our series D preferred shares to date as follows: Declaration Date January 13, 2023 April 13, 2023 July 13, 2023 October 16, 2023 Record Date Payment Date Dividend Per Share January 31, 2023 February 15, 2023 April 28, 2023 July 31, 2023 May 15, 2023 August 15, 2023 October 31, 2023 November 15, 2023 $ $ $ $ 0.40625 0.40625 0.40625 0.40625 The following characterizes distributions paid per preferred share for the years ended December 31, 2023, 2022, and 2021: Ordinary income Return of capital Capital gain Unrecaptured Section 1250 gain Note 6.

The ownership of an OP Unit and a common share of beneficial interest have essentially the same economic characteristics. Distributions with respect to OP Units will generally mirror distributions with respect to the Company’s common shares. Unitholders (other than the Company) generally have the right, commencing six months from the date of issuance of such OP Units, to cause the Operating Trust to redeem their OP Units in exchange for cash or, at the option of the Company, common shares of the Company on a one-for-one basis. As sole trustee, the Company has the sole discretion to elect whether the redemption right will be satisfied by the Company in cash or the Company’s common shares. As a result, the Noncontrolling interest is classified as permanent equity. As of December 31, 2023, the portion of the Operating Trust not beneficially owned by the Company is in the form of OP Units and LTIP Units (see Note 8 for a description of LTIP Units). LTIP Units may be subject to additional vesting requirements. The following table presents the changes in Equity Commonwealth’s issued and outstanding common shares and units for the year ended December 31, 2023: Outstanding at January 1, 2023 Repurchase and surrender of shares OP Unit redemption Share-based compensation grants and vesting, net of forfeitures Outstanding at December 31, 2023 Noncontrolling ownership interest in the Operating Trust Common Shares OP Units and LTIP Units Total 109,428,252 279,892 109,708,144 (3,152,604) — (3,152,604) 135,392 436,398 (135,392) — 81,518 517,916 106,847,438 226,018 107,073,456 0.21 % The carrying value of the Noncontrolling interest is allocated based on the number of OP Units and LTIP Units in proportion to the number of OP Units and LTIP Units plus the number of common shares. We adjust the Noncontrolling interest balance at the end of each period to reflect the noncontrolling partners’ interest in the net assets of the Operating Trust. Net income is allocated to the Noncontrolling interest in the Operating Trust based on the weighted average ownership percentage during the period. Equity Commonwealth’s weighted average ownership interest in the Operating Trust was 99.69%, 99.75% and 99.80%, respectively, for the years ended December 31, 2023, 2022 and 2021.

Income Taxes Our provision for income taxes consists of the following (in thousands): Current: State and local Federal Income tax expense Year Ended December 31, 2023 2022 2021 $ $ (50) $ (1,816) (1,866) $ (103) $ (350) (453) $ (120) — (120) During the years ended December 31, 2023, 2022 and 2021, we recorded benefit of $0.1 million, $0.0 million and $0.1 million, respectively, related to uncertain tax positions, as part of our income tax provision. A reconciliation of our effective tax rate and the U.S. Federal statutory income tax rate is as follows: Taxes at statutory U.S. federal income tax rate Dividends paid deduction and net operating loss utilization Federal taxes State and local income taxes Effective tax rate Year Ended December 31, 2023 2022 2021 21.00 % (21.00) % 1.95 % 0.05 % 2.00 % 21.00 % (21.00) % 0.93 % 0.27 % 1.20 % 21.00 % (21.00) % — % (0.74) % (0.74) % On November 30, 2023 and August 31, 2022, the Company completed internal restructurings intended to comply with Section 351 of the Internal Revenue Code. As a result, for the years ended December 31, 2023 and 2022, the Operating Trust recognized $200.0 million and $82.0 million taxable gains, respectively, for federal income tax purposes. The gains were distributed by the Company and have no impact on the Company’s provision for income taxes for the years ended December 31, 2023 and 2022. At December 31, 2023 and 2022, we had federal net operating loss, or NOL, carryforwards of $29 million and $29 million, respectively. These amounts can be used to offset future taxable income, if any. The REIT will be entitled to utilize NOL carryforwards only to the extent that REIT taxable income exceeds our deduction for dividends paid. NOLs arising in taxable years ending before January 1, 2018 can generally be carried forward 20 years, with no carryforward limitation on NOLs generated after that date. NOL carryforwards of $18 million expire in 2037 and NOL carryforwards of $11 million never expire. Note 8. Share-Based Compensation Equity Commonwealth 2015 Omnibus Incentive Plan (2015 Incentive Plan) On June 16, 2015, at our 2015 annual meeting of shareholders, our shareholders approved the 2015 Incentive Plan. The 2015 Incentive Plan replaced the Equity Commonwealth 2012 Equity Compensation Plan (as amended, the 2012 Plan). The Board of Trustees approved the 2015 Incentive Plan, subject to shareholder approval, on March 18, 2015 (the Effective Date). On January 26, 2016, the Board of Trustees approved an amendment to the 2015 Incentive Plan to allow the Compensation Committee (Committee) to authorize in an award agreement a transfer of all or a part of certain equity awards not for value to a “family member” (as defined in the 2015 Incentive Plan). At our annual meeting of shareholders on June 20, 2019, our shareholders approved an amendment to the 2015 Incentive Plan to increase the number of common shares of beneficial interest authorized thereunder by 2,500,000 (hereafter, as amended, the 2015 Incentive Plan). At our annual meeting of shareholders on June 13, 2023, our shareholders approved an amendment to the 2015 Incentive Plan to increase the number of common shares of beneficial interest authorized thereunder by 1,650,000 The following description of certain terms of the 2015 Incentive Plan is qualified in all respects by the terms of the 2015 Incentive Plan. Eligibility. Awards may be granted under the 2015 Incentive Plan to employees, officers and non-employee directors of the Company, its subsidiaries or its affiliates, or consultants and advisors (who are natural persons) providing services to the F-15 EQUITY COMMONWEALTH NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (Continued) Company, its subsidiaries or its affiliates, or any other person whose participation in the 2015 Incentive Plan is determined by the Committee to be in the best interests of the Company. Term. The 2015 Incentive Plan terminates automatically ten years after the Effective Date, unless it is terminated earlier by the Board of Trustees. Shares Available for Issuance. Subject to adjustment as provided in the 2015 Incentive Plan, the maximum number of common shares of the Company that are available for issuance under the 2015 Incentive Plan is 7,400,000 shares. Awards. The following types of awards may be made under the 2015 Incentive Plan, subject to limitations set forth in the 2015 Incentive Plan: · Stock options; · Stock appreciation rights; · Restricted stock; · Restricted stock units; · Unrestricted stock; · Dividend equivalent rights; · Performance shares and other performance-based awards; · Limited partnership interests in any partnership entity through which the Company may conduct its business in the future; · Other equity-based awards; and · Cash bonus awards. Recipients of the Company’s restricted shares have the same voting rights as any other common shareholder. During the period of restriction, holders of unvested restricted shares are eligible to receive dividend payments on their shares at the same rate and on the same date as any other common shareholder. The restricted shares are service based awards and vest over a service period determined by the Committee. Recipients of the Company’s restricted stock units, or RSUs, are entitled to receive dividends with respect to the common shares underlying the RSUs if and when the RSUs are earned, at which time the recipient will be entitled to receive an amount in cash equal to the aggregate amount of cash dividends that would have been paid in respect to the common shares underlying the recipient’s earned RSUs had such common shares been issued to the recipient on the first day of the performance period. To the extent that an award does not vest, the dividends related to unvested RSUs will be forfeited. The RSUs are market-based awards with a service condition and recipients may earn RSUs based on the Company’s total shareholder return, or TSR, relative to the TSRs of the companies that comprise the Nareit Office Index over a three-year performance period. Following the end of the three-year performance period, the number of earned awards will be determined. The earned awards vest in two tranches with 50% of the earned award vesting following the end of the performance period on the date the Committee determines the level of achievement of the performance metric and the remaining 50% of the earned award vesting approximately one year thereafter, subject to the grant recipient’s continued employment. Compensation expense for the RSUs is determined using a Monte Carlo simulation model and is recognized ratably from the grant date to the vesting date of each tranche. LTIP Units are a class of beneficial interests in the Operating Trust that may be issued to employees, officers or trustees of the Operating Trust, the Company or their subsidiaries, or LTIP Units. Time-based LTIP Units have the same general characteristics as restricted shares and market-based LTIP Units have the same general characteristics as RSUs. Each LTIP Unit will convert automatically into an OP Unit on a one-for-one basis when the LTIP Unit becomes vested and its capital account is equalized with the per-unit capital account of the OP Units. Holders of LTIP Units generally will be entitled to receive the same per-unit distributions as the other outstanding OP Units in the Operating Trust, except that market-based LTIP Units will not participate in distributions until expiration of the applicable performance period, at which time any earned market-based LTIP Units generally will become entitled to receive a catch-up distribution for the periods prior to such time. Administration. The 2015 Incentive Plan will be administered by the Committee, which will determine all terms and recipients of awards under the 2015 Incentive Plan. 2023 Equity Award Activity On January 26, 2023, the Compensation Committee approved grants in the aggregate amount of 132,794 restricted shares and 269,609 RSUs at target (672,000 RSUs at maximum) to the Company’s officers, certain employees, and to Mr. Zell, the F-16 EQUITY COMMONWEALTH NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (Continued) former Chairman of our Board of Trustees, as part of their compensation for fiscal year 2022. The restricted shares were valued at $25.61 per share, the closing price of our common shares on the New York Stock Exchange, or the NYSE, on the grant date. On June 13, 2023, in accordance with the Company’s compensation program for independent Trustees, the Committee awarded each of the six independent Trustees $0.1 million in restricted shares or time-based LTIP Units as part of their compensation for the 2023-2024 year of service on the Board of Trustees. These awards equated to 5,773 shares or time-based LTIP Units per Trustee, for a total of 28,865 shares and 5,773 time-based LTIP Units, valued at $20.79 per share and unit, the closing price of our common shares on the NYSE on that day. These shares and time-based LTIP Units vest one year after the date of the award, on June 13, 2024. During the year ended December 31, 2023, 274,739 RSUs vested, and, as a result, we issued 274,739 common shares, prior to certain employees surrendering their common shares to satisfy tax withholding obligations (see Note 5). 2022 Equity Award Activity On January 26, 2022, the Compensation Committee approved grants in the aggregate amount of 29,071 time-based LTIP Units, 59,024 market-based LTIP Units at target (147,117 market-based LTIP Units at maximum) 92,573 restricted shares and 187,951 RSUs at target (468,468 RSUs at maximum) to the Company’s officers, certain employees, and to Mr. Zell, the former Chairman of our Board of Trustees, as part of their compensation for fiscal year 2021.

On June 21, 2022, in accordance with the Company’s compensation program for independent Trustees, the Committee awarded each of the six independent Trustees $0.1 million in restricted shares or time-based LTIP Units as part of their compensation for the 2022-2023 year of service on the Board of Trustees. These awards equated to 3,604 shares or time-based LTIP Units per Trustee, for a total of 18,020 shares and 3,604 time-based LTIP Units, valued at $27.75 per share and unit, the closing price of our common shares on the NYSE on that day. These shares and time-based LTIP Units vested on June 21, 2023. During the year ended December 31, 2022, 382,993 RSUs vested, and, as a result, we issued 382,993 common shares, prior to certain employees surrendering their common shares to satisfy tax withholding obligations (see Note 5). 2021 Equity Award Activity On January 25, 2021, the Committee approved grants in the aggregate amount of 122,466 restricted shares and 248,646 RSUs at target (619,750 RSUs at maximum) to the Company’s officers, certain employees, and to Mr. Zell, the former Chairman of our Board of Trustees, as part of their compensation for fiscal year 2020. The restricted shares were valued at $28.25 per share, the closing price of our common shares on the NYSE on the grant date.

These awards equated to 3,701 shares or time-based LTIP Units per Trustee, for a total of 18,505 shares and 3,701 time-based LTIP Units, valued at $27.02 per share and unit, the closing price of our common shares on the New York Stock Exchange, or NYSE, on that day. These shares and time-based LTIP Units vested on June 23, 2022. During the year ended December 31, 2021, 523,662 RSUs vested, and, as a result, we issued 523,662 common shares, prior to certain employees surrendering their common shares to satisfy tax withholding obligations (see Note 5).

RSUs and market- based LTIP Units not earned are the shares market-based award recipients do not receive based on the performance measurement completed at the end of the performance period. The 330,591 unvested restricted shares and time-based LTIP Units as of December 31, 2023 are scheduled to vest as follows: 113,107 shares/units in 2024, 90,554 shares/units in 2025, 73,427 shares/units in 2026 and 53,503 shares/units in 2027. As of December 31, 2023, the estimated future compensation expense for all unvested restricted shares and time-based LTIP Units was $4.3 million. Compensation expense for the restricted share and time-based LTIP Units is being recognized on a straight-line basis over the requisite service period for each separately vesting portion of the award. The weighted average period over which the future compensation expense will be recorded for the restricted shares and time-based LTIP Units is approximately 2.3 years. As of December 31, 2023, the estimated future compensation expense for all unvested RSUs and market-based LTIP Units was $9.7 million. The weighted average period over which the future compensation expense will be recorded for the RSUs and market-based LTIP Units is approximately 2.2 years.

Compensation expense recorded during the years ended December 31, 2023, 2022 and 2021 includes $5.2 million, $0.4 million and $3.5 million, respectively, of accelerated vesting due to the passing of our former Chairman in 2023 and staffing reductions in 2022 and 2021. Forfeitures are recognized as they occur. At December 31, 2023, 2,073,350 shares/units remain available for issuance under the 2015 Incentive Plan. Note 9. Fair Value of Assets and Liabilities As of December 31, 2023 and 2022, we do not have any assets or liabilities measured at fair value. Financial Instruments Our financial instruments include our cash and cash equivalents. At December 31, 2023 and 2022, the fair value of these financial instruments was not different from their carrying values. Other financial instruments that potentially subject us to concentrations of credit risk consist principally of rents receivable.
