PART I

Item 1. Business.

EQC Organization. WeEQC ~~are~~was ~~an internally managed and self-advised real estate investment trust (“REIT”). We were~~ formed in 1986 under Maryland law, ~~and~~electing ~~we have elected~~ to be taxed as a real estate investment trust (“REIT”) under the Internal Revenue Code of 1986, as amended, (the “Code”). ~~The~~Prior to its dissolution on June 13, 2025, the Company ~~operates~~was an internally managed and self-advised REIT operating as what is commonly referred to as an umbrella partnership real estate investment trust (“UPREIT”), conducting substantially all of its activities through EQC Operating Trust, a Maryland real estate investment trust (the “Operating Trust”), which was also dissolved on June 13, 2025.

~~The~~Prior to its dissolution on June 13, 2025, the Company beneficially owned 99.86% of the outstanding shares of beneficial interest, designated as units (“OP Units”) in the Operating Trust, ~~as of December 31, 2024,~~ and the Company iswas the sole trustee of the Operating Trust. As the sole trustee, the Company generally ~~has~~had 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.

~~The~~EQC ~~Company~~Background. In 2014, ~~we took over responsibility for the Company when~~ EQC’s shareholders voted to replace EQC’s then-existing board of trustees. EQC’s new Board of Trustees (the “Board”) appointed a new team of executive officers and internalized management. The Board and management team then undertook a comprehensive review of the Company, its legal and capital structures and its portfolio of properties, which were primarily office buildings in the United States. WeEQC executed a strategy that focused on disposing of a significant portion of the Company’s assets to reshape the portfolio and generate liquidity to fund future investments in high-quality assets or businesses to create a foundation for long-term growth to maximize shareholder value.

From 2014 to the onset of the COVID-19 pandemic in early 2020, the Company completed over $7.6 billion of dispositions. At the same time, and through the middle of 2024, weEQC evaluated over 100 potential investment opportunities to create long-term value for shareholders. These investment opportunities spanned a wide range of property sectors, including office, retail, single-family rental, lodging, life sciences, industrial, manufactured housing, multi-family rentals and self-storage and to a lesser extent healthcare, data centers, cell towers and infrastructure. Despite ~~our~~the Company’s efforts, weit ~~were~~was unable to consummate a transaction in line with ~~our~~its strategy.

While evaluating potential investment opportunities in an effort to create long-term value for ~~our~~its shareholders, wethe Company concurrently took steps to facilitate the potential wind-down of ~~our~~its business. On July 30, 2024, ~~our~~after being unable to consummate a transaction in line with the Company’s strategy, the Company’s Board: (i) determined that it was advisable and in the best interests of ~~our~~the Company’s shareholders to proceed with the wind-down of ~~our~~its operations and the liquidation of ~~our~~its assets in order to maximize shareholder value, and (ii) directed the Company’s management team to prepare proxy materials seeking shareholder approval of a plan of sale and dissolution.

Plan of Sale. On October 2, 2024, the Company filed a definitive proxy statement (the “Definitive Proxy”) with the U.S. Securities and Exchange Commission (the “SEC”) related to a special meeting of shareholders for the following purposes: (i) to consider and vote upon the Plan of Sale and Dissolution of the Company (the “Plan of Sale”), including the wind-down and complete liquidation of the Company, and the dissolution and termination of the Company, including the establishment of a Liquidating Entity (as defined in the Definitive Proxy), and (ii) on an advisory, non-binding basis, to consider and vote upon the compensation ~~that may become~~ payable by the Company to its named executive officers in connection with the Plan of Sale (the “Executive Compensation Proposal”). The Plan of Sale, which the Board determined was in the best interests of the Company and its shareholders, ~~authorizes~~authorized the Company to sell its remaining properties, wind-down the Company’s affairs and distribute the net proceeds to shareholders. At the special shareholder meeting held on November 12, 2024, the Company’s shareholders approved both proposals with: (i) 85.5% of outstanding shares, and 99% of votes cast, in favor of the Plan of Sale proposal (two-thirds of outstanding shares required for approval), and (ii) 86.7% of votes cast in favor of the Executive Compensation Proposal (majority of votes cast required for approval).

~~Pursuant~~EQC toLiquidating Trust. On June 13, 2025 (the “Effective Date”), as part of the Plan of Sale, the Company ~~accomplished~~transferred ~~the~~its ~~following~~remaining inassets ~~2024~~and liabilities to ~~facilitate~~EQC ~~the~~LT, ~~efficient~~a ~~wind~~newly-~~down~~created Maryland common law trust, for the benefit of the common shareholders of the Company. In conjunction with the transfer, EQC LT distributed all of its ~~business:~~units of beneficial interests to EQC’s common shareholders on a one-for-one basis, with each common shareholder receiving one unit in EQC LT (the “Units”) for each EQC common share then held of record. All outstanding EQC common shares were then cancelled, and the Company was dissolved and terminated.

•Paid the liquidation preference to the holders of shares of the Company’s 6.50% Series D Cumulative Convertible Preferred Shares of beneficial interest, par value $0.01 per share (the “Series D Preferred Shares”), constituting all amounts due and owing such holders, in conjunction with which a Form 25 was filed with the SEC to effect the withdrawal of the Series D Preferred Shares from the New York Stock Exchange (“NYSE”);

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.

Corporate Responsibility. We believe that sustainability, social responsibility and strong corporate governance (collectively, “Corporate Responsibility”) are key contributors to success. Our approach to Corporate Responsibility matters addresses our effect on the environment, our social impact and our relationships with our stakeholders, including our shareholders, 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 the senior member of our sustainability team, regularly update our Board on sustainability initiatives.

We are committed to continue the Company’s sustainability and social responsibility initiatives to the extent they are aligned with the Plan of Sale and wind-down process.

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.

For a more thorough description of the Company’s Corporate Responsibility initiatives, please see the Company’s 2024 Corporate Responsibility Report in the investor relations “Corporate Responsibility” portion of the Company’s website at

www.eqcre.com. The 2024 Corporate Responsibility Report, which was published following the review and approval of our Board, is not part of or incorporated into this Annual Report on Form 10-K.

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 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 27, 2025, 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, 2021 through our taxable year ended December 31, 2024. 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 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.

You should carefully consider the following~~ risk factors ~~together with all of the other information contained in this Annual Report on Form 10-K~~.

Risk Factors Related to Plan of Sale

We cannot assure you of the actual amount you will receive in liquidating distributions or when you will receive them.

The remaining liquidating distributions are based on estimates involving certain assumptions and judgments and do not reflect the actual amount that our shareholders will receive in liquidating distributions. The actual amount we will distribute to you may be higher or lower than our estimated liquidating distributions if our liabilities are greater or less than we expect. In addition, the actual amount we will distribute to you may be higher or lower than our estimated liquidating distributions due to expenses incurred and revenue generated prior to dissolution, operational and general administrative expenses, wind-down costs, taxes, estimated costs or liabilities related to pending and any future litigation, and other liabilities that may be incurred by the Company. Our estimated liquidating distributions do not take into account interest rate, market conditions or other factors occurring after we determined our estimates, which may cause the aggregate amount of liquidating distributions to be more or less than our estimates.

If our Plan of Sale costs or unpaid liabilities are greater than we expect, our liquidating distributions may be delayed or reduced.

Before making the final liquidating distribution, we will need to pay or arrange for the payment of all of our transaction costs in the Plan of Sale and all other costs and all valid claims of our creditors and claimants. Our Board may also decide to establish a reserve fund to pay contingent claims. To the extent that we have underestimated these costs in calculating our estimated liquidating distributions, our actual liquidating distributions may be lower than our estimated liquidating distributions. Further, if a reserve fund is established, payment of liquidating distributions to our shareholders may be delayed or reduced.

Our shareholders could, in some circumstances, be held liable for amounts they received from us in connection with our dissolution.

Under Maryland law, certain obligations or liabilities of our shareholders, trustees or officers may not be avoided by our dissolution. For example, if we make liquidating distributions to our shareholders without making adequate provisions for payment of creditors’ claims (including litigation claims), our shareholders may be liable to the creditors to the extent of the liquidating distributions to them in excess of the amount of any payments due to creditors, up to the amounts previously received by such shareholder from us. Accordingly, in such event, a shareholder could be required to return all liquidating distributions previously made to such shareholder and a shareholder could receive less or nothing from us under the Plan of Sale. Moreover, in the event a shareholder has paid taxes on amounts previously received as a liquidating distribution, a repayment of all or a portion of such amount could result in a shareholder incurring a net tax cost if the shareholder’s repayment of an amount previously distributed does not cause a commensurate reduction in taxes payable. To the extent that we have underestimated the size of our contingency reserve and liquidating distributions to our shareholders have already been made, our shareholders may be required to return some of the liquidating distributions.

Our Board, under certain circumstances, may terminate the Plan of Sale without shareholder approval at the Board’s discretion, and may also otherwise modify or amend the Plan of Sale at any time after it is approved by our shareholders.

Notwithstanding approval of the Plan of Sale by our shareholders, under certain circumstances, our Board may terminate the Plan of Sale without shareholder approval at the Board’s discretion and authorize us to seek a merger, business combination or similar transaction, as a result of which you may receive a different amount or form of consideration than otherwise provided for under the Plan of Sale. This power of termination may be exercised up to the time that a Notice of Termination of Existence has been accepted for recording by the State Department of Assessments and Taxation of Maryland (the “SDAT”). In addition, our Board may modify or amend the Plan of Sale without further action by our shareholders to the extent permitted under then current law if the Board concludes that such modification or amendment is in the best interests of our shareholders. Any termination or modification may impact the timing and amount of liquidating distributions.

Pursuing the Plan of Sale may cause us to fail to qualify as a REIT, which could significantly lower the amount of our liquidating distributions.

For so long as we qualify as a REIT and distribute all of our taxable income, we generally are not subject to U.S. federal income tax. However, there is a risk that our actions in pursuit of the Plan of Sale may cause us to fail to meet one or more of the requirements that must be met in order to qualify as a REIT. For example, to qualify as a REIT, at least 75% of our gross income must come from real estate sources and 95% of our gross income must come from real estate sources and certain other sources that are itemized in the REIT tax laws, mainly interest and dividends. We may encounter difficulties satisfying these or other REIT requirements as part of the liquidation process. We expect to remain qualified as a REIT until our final REIT tax

year ends, when we transfer any remaining assets and liabilities to the Liquidating Entity. If we are unable to maintain our REIT status in 2025 or future taxable years, we will, among other things (unless entitled to relief under certain statutory provisions):

•not be allowed a deduction for dividends paid to shareholders in computing our taxable income;

•be subject to federal income tax on our taxable income, including recognized gains, at regular corporate rates;

•be subject to increased state and local taxes; and

•be disqualified from treatment as a REIT for the taxable year in which we lose our qualification and for the four following taxable years.

As a result of these consequences, our failure to qualify as a REIT could substantially reduce the funds available for liquidating distributions to our shareholders.

We previously owned office properties and hold and/or held cash and cash equivalents through two subsidiary entities which are intended to qualify as REITs (the “Subsidiary REITs”). The Subsidiary REITs are subject to the various REIT qualification requirements and other limitations. If one of the Subsidiary REITs were to fail to qualify as a REIT: (i) the Subsidiary REIT would become subject to U.S. federal income tax and could become subject to increased state and local taxes, (ii) shares in the 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, and we could fail to qualify as a REIT, unless we avail ourselves of certain relief provisions.

Pursuing the Plan of Sale may cause us to be subject to a 100% excise tax on the net income from “prohibited transactions,” which would reduce the amount of our liquidating distributions.

So long as we continue to qualify as a REIT, any net gain from “prohibited transactions” will be subject to a 100% tax. “Prohibited transactions” are sales of property held primarily for sale to customers in the ordinary course of a trade or business. The prohibited transactions tax is intended to prevent a REIT from retaining any profit from ordinary retailing activities such as sales to customers of condominium units or subdivided lots in a development project. The Code provides for a “safe harbor” which, if all its conditions are met, would protect a REIT’s property sales from being considered prohibited transactions. Whether an asset is property held primarily for sale to customers in the ordinary course of a trade or business is a highly factual determination. We expect the asset sales made pursuant to the Plan of Sale to either qualify for the safe harbor or otherwise not be subject to the prohibited transactions tax. There can be no assurance, however, that such sales will qualify for the safe harbor or the Internal Revenue Service (the “IRS”) will not successfully challenge the characterization of properties we hold for purposes of applying the prohibited transactions tax.

Because liquidating distributions may be made in multiple tax years, if we were to terminate the Plan of Sale in a tax year subsequent to one in which we had already made liquidating distributions, the timing and character of your taxation with respect to liquidating distributions made to you in the prior tax year could change, which may obligate you to file amended tax returns and subject you to greater tax liability with respect to the prior tax year than you would otherwise have been subject to.

If we were to terminate the Plan of Sale in a tax year subsequent to one in which we had already made liquidating distributions, you may be obligated to file amended tax returns, which could subject you to greater tax liability with respect to the prior tax year than to which you would otherwise have been subject. For U.S. holders, distributions to you under the Plan of Sale generally should not be taxable to you for U.S. federal income tax purposes until the aggregate amount of liquidating distributions to you exceeds your adjusted tax basis in your common shares, and then should be taxable to you as capital gain (assuming you hold your shares as a capital asset). However, if we terminate the Plan of Sale, the U.S. federal income tax treatment of liquidating distributions already made pursuant to the Plan of Sale would change because they would no longer be treated as having been made as part of our complete liquidation. Instead, any such liquidating distributions would be treated as either a distribution made with respect to the shares you hold, subject to the normal rules of U.S. federal income tax for distributions, or as payment to you for the sale or exchange of your shares in partial redemption of them. Whether sale or distribution treatment would apply to you would depend on your particular circumstances and various other factors and we cannot predict which would apply; however, regardless of which treatment would apply, each distribution likely would be at least partially taxable to you, in which case you would have to file amended returns and pay any additional taxes that may be due. Certain shareholders may be subject to special rules.

Non-U.S. shareholders may be subject to U.S. federal withholding tax and U.S. federal income tax on liquidating distributions received from us.

Pursuant to the Foreign Investment in Real Property Tax Act of 1980 and other guidance by the IRS, liquidating distributions to the extent attributable to sales or exchanges of “U.S. real property interests” generally will be taxed to a non-U.S. shareholder as if such gain were effectively connected with a U.S. trade or business. As a result, non-U.S. shareholders may be subject to U.S. federal withholding tax and U.S. federal income tax on liquidating distributions from us. However, liquidating distributions generally will not be treated as effectively connected income if (a) the distribution is received with respect to shares that are regularly traded on an established securities market located in the United States and (b) the non-U.S. shareholder does not own more than 10% of our common shares at any time during the one year period ending on the date the liquidating distribution is received.

Distributing interests in or conversion to a Liquidating Entity may cause you to recognize gain prior to the receipt of cash.

Our Board may cause the Company to transfer its remaining assets and liabilities to or convert the Company to a Liquidating Entity if our Board determines, in its discretion, that it is advisable or appropriate to do so. Such a transfer or conversion would be treated as a distribution of our remaining assets to our shareholders, together with a contribution of the assets to the Liquidating Entity. As a result, in such case, you would recognize gain to the extent that your share of the cash and the fair market value of any assets (less any liabilities assumed for tax purposes) received or initially held by the Liquidating Entity was greater than your basis in your common shares, regardless of whether you contemporaneously receive a distribution of cash with which to satisfy any resulting tax liability, and the Company may have withholding tax obligations with respect to non-U.S. shareholders. In addition, it is possible that the fair market value of the assets received or initially held by the Liquidating Entity, as estimated for purposes of determining the extent of your gain at the time at which interests in the Liquidating Entity are distributed to the shareholders, will exceed the cash or fair market value of property received by the Liquidating Entity on a later sale of the assets. In this case, you could recognize a loss in a taxable year subsequent to the taxable year in which the gain was recognized, the deductibility of which may be limited under the Code. The distribution to shareholders of interests in or the conversion of the Company to a Liquidating Entity may also cause ongoing adverse tax consequences (particularly to tax-exempt and non-U.S. shareholders, which may be required to file U.S. tax returns with respect to their share of income generated by the Liquidating Entity).

Shareholder litigation related to the Plan of Sale could result in substantial costs and distract our management.

Historically, extraordinary corporate actions by a company, such as the proposed Plan of Sale, often lead to securities class action or other shareholder lawsuits being filed against that company. Such litigation may be expensive and protracted and, even if we ultimately prevail, the process of defending against lawsuits may divert management’s attention from implementing the Plan of Sale and operating our business. We cannot provide any assurance regarding the outcome of any claims that may arise in the future. We also have indemnified 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 could result in substantial costs. 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 and our liquidating distributions may be delayed or reduced.

We will continue to incur the expenses of complying with public company reporting requirements.

Until our liquidation and dissolution is complete, we will have an obligation to continue to comply with the applicable reporting requirements of the Exchange Act. In order to minimize expenses, at a future date as our Board determines, our Board anticipates that it will authorize our executive officers to file the Notice of Termination of Existence and cause EQC to delist our common shares from the NYSE and file a Form 15 (or take other appropriate action) to deregister our common shares under the Exchange Act, thereby terminating/suspending EQC’s reporting requirements under the Exchange Act. Following such termination/suspension, we will continue to file current reports on Form 8-K to disclose material events relating to the Company’s liquidation and dissolution, along with any other reports that the SEC might require of any Liquidating Entity, but would discontinue filing EQC’s annual and quarterly reports on Forms 10-K and 10-Q, respectively. However, if we no longer satisfy the requirements under which we were able to cease the Company’s reporting under the Exchange Act, such reporting obligations would return and we would incur these expenses, which would reduce the amount you receive in liquidating distributions. To the extent that we delay filing the Notice of Termination of Existence and the delisting of EQC’s common shares from the NYSE, the Company would be obligated to continue complying with the applicable reporting requirements of the Exchange Act.

Our common shares will be delisted from the NYSE at a future date to be determined by the Board or the NYSE.

In connection with the Plan of Sale, at a future date as our Board determines, we anticipate that we will voluntarily delist our Common Shares from the NYSE, subject to the rules of the NYSE and our Declaration of Trust, in order to reduce our operating expenses and maximize our liquidating distributions. Under the rules of the NYSE, the exchange has discretionary authority to delist our common shares. In addition, the exchange may commence delisting proceedings against us if (i) the average closing price of our common shares falls below $1.00 per share over a 30-day consecutive trading period, (ii) our average market capitalization falls below $15 million over a 30-day consecutive trading period or (iii) we lose our REIT qualification. Once our common shares are delisted, you may have difficulty trading common shares on the secondary market and the value of your investment may be reduced. Moreover, if we establish or convert into a Liquidating Entity, the interests in the Liquidating Entity will not be transferable except by will, intestate succession or operation of law.

Risks Related to Our Business

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 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.

Any environmental contamination or other environmental liabilities could materially and adversely affect us.

Under various federal, state and local laws and regulations, as the 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 property 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 former properties, we may remain responsible for costs and liabilities arising from environmental issues related to representations and warranties we made 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 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, 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 property.

We and our former 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 to governmental fines or private litigant damage awards, which could reduce the amount of liquidating distributions we pay to our shareholders. In addition, compliance with these requirements, including new requirements or stricter interpretation of existing requirements, may require 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. Our reputation could be negatively affected if we violate environmental, health or safety laws or regulations.

Buildings and other structures on the properties that we formerly owned or operated contain, may contain, or may have contained, asbestos-containing material (“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 sold buildings and third parties may seek recovery from former 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 sold buildings could expose us to costs and liabilities to address these issues, including from third parties if property damage or personal injury occurs.

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 former 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 and our ability to pay liquidating distributions.

Risks Related to Our Securities

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, 2024, we held $160.5 million 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 (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, which could have an adverse effect on the timing or amount of the liquidating distributions.

Changes in market conditions could adversely affect the market price of our common shares.

As with other publicly traded equity securities, our common share 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;

•the delisting of our common shares in connection with the Plan of Sale;

•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, which would reduce the amount of liquidating distributions we pay to our shareholders.

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 the perception that such issuances might occur, could adversely affect the per share trading price of our common shares. Any such future issuances may be dilutive to 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 (beneficially or constructively) 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, upon the written request of shareholders entitled to cast not less than 10% of all the votes entitled to be cast at a special meeting, our Chief Executive Officer 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.

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 liquidating 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 liquidating 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 with respect to the liquidating distributions.

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 except for willful misfeasance, bad faith, gross negligence or reckless disregard of duty. 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.

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 liquidating 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 and could, in turn, have an adverse effect on the timing or amount of the liquidating distributions.

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 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.

We previously owned office properties and hold and/or held cash and cash equivalents through two Subsidiary REITs. The Subsidiary REITs are 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.

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, 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. In light of the Plan of Sale, 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, or take other steps which could adversely affect our cash flow.

The tax on “prohibited transactions” may apply to our real property sales.

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 that we have made 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 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.

~~The~~EQC ~~Company~~and ~~maintains~~EQC LT maintained a cybersecurity program focused on preventing, identifying and mitigating ~~cyber threats~~ applicable tocyber ~~its business, including as a former owner and operator of commercial office properties~~threats. ~~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~~A ~~Company employs a~~ number of cybersecurity measures ~~intended~~were employed to reduce the likelihood that cybersecurity incidents would 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.2

We also created and maintained processes that provided a playbook in the event of a cyber incident. These processes provided assessment and response tools designed to mitigate damage from attacks and integrate third-party digital forensics, legal providers and law enforcement as part of the response plan. We also instituted a variety of safeguards to counter ransomware threats.

We integrated our cybersecurity program into our overall risk management processes by instituting corporate measures and protocols to ensure ongoing operations in the event of a disaster or major business disruption affecting the corporate headquarters, infrastructure or key personnel. Our employee guidelines also addressed 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.

OVERVIEW

WeEQC ~~are~~was anformed ~~internally~~in ~~managed~~1986 ~~and~~under ~~self-advised~~Maryland ~~REIT~~law. Prior Weto ~~were~~its ~~formed~~dissolution inon ~~1986~~June 13, ~~under~~2025, ~~Maryland~~EQC ~~law. The~~was ~~Company~~an ~~operates~~internally managed and self-advised REIT operating as an UPREIT, conducting substantially all of its activities through the Operating Trust, which was also dissolved on June 13, 2025. AsPrior ofto ~~December~~its dissolution on June 3113, ~~2024~~2025, the Company beneficially owned 99.86% of the outstanding OP Units.

In 2014, ~~we took over responsibility for the Company when~~ EQC’s shareholders voted to replace EQC’s then-existing board of trustees. EQC’s new Board appointed a new team of executive officers and internalized management. The Board and management team then undertook a comprehensive review of the Company, its legal and capital structures and its portfolio of properties. WeEQC executed a strategy that focused on disposing of a significant portion of the Company’s assets to reshape ~~the~~its portfolio and generate liquidity to fund future investments in high-quality assets or businesses to create a foundation for long-term growth to maximize shareholder value.

On October 2, 2024, the Company filed the Definitive Proxy with the SEC related to a special meeting of shareholders for the following purposes: (i) to consider and vote upon the Plan of Sale, including the wind-down and complete liquidation of the Company, and the dissolution and termination of the Company, including the establishment of a Liquidating Entity and (ii) on an advisory, non-binding basis, to consider and vote upon the Executive Compensation Proposal. The Plan of Sale, which the Board determined was in the best interests of the Company and its shareholders, ~~authorizes~~authorized the Company to sell its remaining properties, wind-down the Company’s affairs and distribute the net proceeds to shareholders. At the special shareholder meeting held on November 12, 2024, the Company’s shareholders approved both proposals with: (i) 85.5% of outstanding shares, and 99% of votes cast, in favor of the Plan of Sale proposal (two-thirds of outstanding shares required for approval), and (ii) 86.7% of votes cast in favor of the Executive Compensation Proposal (majority of votes cast required for approval). Following the shareholders’ approval of the Plan of Sale, the Company’s efforts were focused on, winding-down the Company’s affairs and distributing the net proceeds to shareholders.

~~Given the Plan of Sale, our efforts are focused on, winding-down the Company’s affairs and distributing the net proceeds to our shareholders.~~5

17On June 13, 2025 (the “Effective Date”), as part of the Plan of Sale, the Company transferred its remaining assets and liabilities to EQC LT, a newly-created Maryland common law trust, for the benefit of the common shareholders of the Company. In conjunction with the transfer, EQC LT distributed all of its units of beneficial interests to EQC’s common shareholders on a one-for-one basis, with each common shareholder receiving one unit in EQC LT (the “Units”) for each EQC common share then held of record. All outstanding EQC common shares were then cancelled, and the Company has been dissolved and terminated.

On September 19, 2025, the trustees of EQC LT approved the termination of EQC LT following the payment of all its liabilities and the disposal of all its assets. After liquidating the assets of EQC and EQC LT, and paying all remaining liabilities, costs and expenses, the trustees of EQC LT determined the amount of remaining funds available did not warrant an additional cash distribution to EQC LT unitholders. The remaining funds totaling approximately $150,000 were donated to ten charities selected by the trustees of EQC LT. As of September 30, 2025, after paying all of its remaining liabilities and disposing of all of its assets, the Liquidating Trust canceled all of its outstanding Units and dissolved.

Since 2014, the Company accomplished the following (i) disposed of 168 properties and three land parcels totaling 45.8 million square feet for an aggregate gross sales price of $7.2 billion, as well as $704.8 million of common shares of Select Income REIT, (ii) retired $3.4 billion of debt and preferred shares, (iii) repurchased $652.1 million of EQC common shares, and (iv) paid $4.0 billion in distributions to EQC common shareholders.

RESULTS OF OPERATIONS

In light of the adoption of liquidation basis accounting as of November 1, 2024, the results of operations for the current year are not comparable to the prior year. As of ~~December~~September 3130, ~~2024~~2025, ~~our portfolio consisted of one 0.7 million square foot property (one building) that was 80.5% leased, and~~ we had ~~$160.5~~no ~~million~~remaining ~~of cash and cash equivalents~~properties. During the year ended December 31, 2024, we sold 1250 H Street, NW in Washington, D.C., and 206 East 9th Street and Bridgepoint Square in Austin, Texas. On February 25, 2025, we sold 1225 Seventeenth Street in Denver, Colorado. ~~We have no remaining properties.~~

LIQUIDITY AND CAPITAL RESOURCES

Our Operating Liquidity and Resources

On November 12, 2024, the Company held a special meeting of shareholders (the “Special Meeting”). At the Special Meeting, the Company'’s shareholders approved the Plan of Sale authorizing the Company to sell its remaining properties, wind-down the Company’s affairs and distribute the net proceeds to shareholders. As of ~~December 31~~September 30, ~~2024~~2025, ~~following our payout of the liquidation preference to the holders of the Series D Preferred Shares and the payout of our Initial Liquidating Distribution of $19.00 per common share,~~ we have ~~$160.5~~no ~~million~~assets ~~of cash~~ and ~~cash equivalents and~~ no debt outstanding. We expect to use our cash balances, cash flow from our operations and proceeds of our property sale to satisfy remaining obligations and make liquidating distributions. We believe our cash balances and the cash flow from our operations, as well as the proceeds from the sale of our asset, will be sufficient to fund these activities. The interest earned on our cash balance depends on the interest rates received from our banks.

Net cash flows provided by (used in) operating, investing and financing activities were $99.1 million, $13.9 million and $(11.1) million, respectively, for the ten months ended October 31, 2024~~, and $122~~.3 million, $(5.7) million and $(538.3) million, respectively, for the year ended December 31, 2023. In light of the adoption of liquidation basis accounting as of November 1, 2024, the changes in these three categories of our cash flows between the ten months ended October, 31, 2024 and the year ended December 31, 2023 are not comparable.

Our Investment and Financing Liquidity and Resources

On November 15, 2024, the Company announced that its Board authorized an initial cash liquidating distribution of $19.00 per common share which was paid on December 6, 2024 to shareholders of record as of November 25, 2024.

NON-GAAP MEASURES

Due to the adoption of the Plan of Sale, we are no longer reporting funds from operations, normalized funds from operations and net operating income, as we no longer consider these to be key performance measures.

CRITICAL ACCOUNTING POLICIES

Below is a discussion of the accounting policies that management believes are or will be critical during our liquidation. We consider these policies critical in that they involve significant management judgments and assumptions, require estimates about matters that are inherently uncertain and because they are important for understanding and evaluating our reported financial results. These judgments affect the reported amounts of assets and liabilities and our disclosure of contingent assets and liabilities as of the dates of the financial statements and the reported amounts of revenue and expenses during the reporting periods. With different estimates or assumptions, materially different amounts could be reported in our financial statements. The accounting policies and practices related to real estate properties discussed below are applicable to any real estate properties owned for the then-applicable period.

18Subsequent to the adoption of the liquidation basis of accounting, we are required to estimate all costs and income we expect to incur and earn through the end of liquidation, including the estimated amount of cash we expect to collect through the disposal of our assets and the estimated costs to dispose of our assets.

~~and~~Pursuant ~~liabilities~~to asour shareholders’ approval of the ~~dates~~Plan of ~~the~~Sale ~~financial~~on ~~statements~~November ~~and~~12, 2024, we adopted the ~~reported~~liquidation ~~amounts~~basis of ~~revenue~~accounting ~~and~~as ~~expenses~~of ~~during~~and for the ~~reporting~~ periods. ~~With~~subsequent ~~different~~to ~~estimates~~November ~~or assumptions~~1, ~~materially~~2024 ~~different~~(as ~~amounts~~approval ~~could~~of bethe ~~reported~~Plan of Sale by our shareholders became imminent in early November 2024 based on the results of our ~~financial~~solicitation ~~statements~~of proxies from our shareholders for their approval of the Plan of Sale). ~~The~~Accordingly, ~~accounting~~on ~~policies~~November ~~and~~1, ~~practices~~2024, ~~related~~assets were adjusted to ~~real~~their ~~estate~~estimated ~~properties~~net ~~discussed~~realizable ~~below~~value, ~~are~~or ~~applicable~~liquidation value, which represents the estimated amount of cash or other consideration that we expected to ~~any~~realize through the disposal of our assets. The liquidation values of our real estate properties ~~owned~~are ~~for~~presented ~~the~~on ~~then-applicable~~a ~~period~~net realizable value basis. Liabilities are carried at their contractual amounts due or estimated settlement amounts.

~~Subsequent~~We toaccrue ~~the adoption of the liquidation basis of accounting, we are required to estimate all~~ costs and income that we expect to incur and earn through the ~~end~~completion of our liquidation, including the estimated amount of cash or other consideration that we ~~expect~~expected to ~~collect~~receive through the date of the disposal of our ~~asset~~assets and the estimated costs to dispose of our ~~asset~~assets, to the extent we have a reasonable basis for estimation. These amounts are classified as a liability for estimated costs in excess of estimated receipts during liquidation on the consolidated statement of net assets. Actual costs and income may differ from amounts reflected in the financial statements because of the inherent uncertainty in estimating future events. These differences may be material. See Note 2, “Plan of Sale” and Note 4, “Liabilities for Estimated Costs in Excess of Estimated Receipts During Liquidation” in our consolidated financial statements for further discussion. Actual costs incurred but unpaid prior to our adoption of the liquidation basis of accounting on November 1, 2024, are included in accounts payable and accrued expenses and distributions payable on the consolidated statement of net assets.

Pursuant to our shareholders’ approval of the Plan of Sale on November 12, 2024, we adopted the liquidation basis of accounting as of and for the periods subsequent to November 1, 2024 (as approval of the Plan of Sale by our shareholders became imminent in early November 2024 based on the results of our solicitation of proxies from our shareholders for their approval of the Plan of Sale). Accordingly, on November 1, 2024, assets were adjusted to their estimated net realizable value, or liquidation value, which represents the estimated amount of cash or other consideration that we expected to realize through the disposal of our asset. The liquidation values of our real estate properties are presented on a net realizable value basis. Liabilities are carried at their contractual amounts due or estimated settlement amounts.

We accrue costs and income that we expect to incur and earn through the completion of our liquidation, including the estimated amount of cash or other consideration that we expected to receive through the date of the disposal of our asset and the estimated costs to dispose of our asset, to the extent we have a reasonable basis for estimation. These amounts are classified as a liability for estimated costs in excess of estimated receipts during liquidation on the consolidated statement of net assets. Actual costs and income may differ from amounts reflected in the financial statements because of the inherent uncertainty in estimating future events. These differences may be material. See Note 2, “Plan of Sale” and Note 4, “Liabilities for Estimated Costs in Excess of Estimated Receipts During Liquidation” for further discussion. Actual costs incurred but unpaid prior to our adoption of the liquidation basis of accounting on November 1, 2024, are included in accounts payable and accrued expenses and distributions payable on the consolidated statement of net assets.

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.

Real Estate Properties

Going Concern Basis

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 were located.

Liquidation Basis of Accounting

As of November 1, 2024, the Company’s real estate was adjusted to its estimated net realizable value, or liquidation value, to reflect the change to the liquidation basis of accounting. The liquidation value represents the estimated amount of cash or other consideration that the Company expected to realize through the disposal of its assets as it carries out the Plan of Sale. The Company estimated the liquidation value of its real estate based on a contractual purchase price for the property. The liquidation value of the Company’s real estate is presented on an undiscounted basis and real estate is no longer depreciated. Subsequent to November 1, 2024, all changes in the estimated liquidation value of the real estate are reflected as a change to the Company’s net assets in liquidation.

From 2014 to the onset of the COVID-19 pandemic in early 2020, the Company completed over $7.6 billion of dispositions. At the same time, and through the middle of 2024, we evaluated over 100 potential investment opportunities to create long-term value for shareholders. These investment opportunities spanned a wide range of property sectors, including office, retail, single-family rental, lodging, life sciences, industrial, manufactured housing, multi-family rentals and self-storage and to a lesser extent healthcare, data centers, cell towers and infrastructure. Despite our efforts, we were unable to consummate a transaction in line with our strategy. 13

32The threshold, target and maximum annual bonus amounts under the STIP for fiscal year 2025, as a percentage of their respective annual base salaries, remained the same as the corresponding amounts that were applicable for fiscal year 2024 for Messrs. Helfand, Griffiths, Weinberg and Shifrin, with such amounts as follows:

● Continued the Company’s sustainability and social responsibility initiatives to the extent they were aligned with the wind-down process (e.g., completed GRESB assessment, published Corporate Responsibility Report, remained actively involved with and provided support for local organizations and community outreach programs); and

● Wound down and dissolved a substantial portion of the Company’s subsidiary entities to facilitate an efficient wind-down of the Company.

Compensation Objectives and Philosophy

Our executive compensation program for 2024, as approved by the Compensation Committee, was designed to accomplish four key objectives:

1. align the interests of our executive officers with the interests of the Company and the Company’s shareholders;

2. reward performance and leadership excellence;

3. fairly compensate executive officers who create value for the Company’s shareholders; and

4. retain and motivate executives to remain at the Company.

Our executive compensation program has the following components: (1) base salary, (2) annual cash incentive compensation, (3) long-term incentive compensation, and (4) health and welfare benefits that are made available to all of our employees.

Compensation Snapshot

	Objectives	Key Features
Base Salary	•Recognize ongoing performance of job responsibilities and leadership excellence•Provide a regular source of income so executives can focus on day-to-day responsibilities	•Fixed compensation paid in cash•Based on competitive pay, taking into account job scope, position, knowledge, skills and experience
Short-Term Annual Incentive Program (STIP)	•Motivate the achievement of Company and individual goals on an annual basis•Reward Company and individual performance and individual leadership excellence	•Variable cash compensation based on achievement of performance goals
Long-Term Incentive Compensation Program (LTIC Program)	•Align the interests of executives with the interests of the Company and the Company’s shareholders •Provide a retention mechanism to motivate our executives to remain at the Company	•Long-term incentive compensation with vesting based on continued service to the Company•Four-year vesting, with a substantial portion back-end loaded (50% vests on the fourth anniversary)

We believe that the structure of our executive compensation program, as outlined above, is both aligned with the interests of our shareholders and serves to retain talented executives as we implement the Plan of Sale.

Executive Compensation Program Highlights

The table below highlights certain practices that we have utilized for our executive officers and others that we have avoided because we believe doing so is in the best interests of our shareholders:

ü	Double Trigger Change in Control Provisions. Upon a change in control, a qualified termination must occur for severance to be paid (window period of 6 months prior to or 2 years following, or otherwise in connection with or anticipation of, a change in control).	û	No Executive Perquisites. We do not provide any supplemental executive retirement plans, company cars, club memberships or other executive perquisites.
ü	Stock Ownership Guidelines. We have stock ownership guidelines in place for our Chief Executive Officer (6x salary) and other named executive officers (3x salary), as well as for our non-employee trustees (4x annual cash retainer) based on average fiscal year common share price.	û	Limited Retirement Benefits. We do not have a defined benefit plan, any supplemental executive retirement plans or any nonqualified deferred compensation plans.
ü	Clawback Policy. Our clawback policy covers all incentive-based compensation (cash and equity) and applies to our current or former named executive officers and certain other officers in the event of a restatement of the Company’s financials. We amended our policy in October 2023 to comply with the finalized and effective SEC and NYSE rules.	û	No Hedging or Pledging of Company Stock. Our anti-hedging and anti-pledging policies prohibit our trustees and executive officers from engaging in hedging and pledging activities.
ü	Independent Compensation Consultant. The Compensation Committee retained an independent compensation consulting firm, FPC, with expertise in the REIT industry.	û	No Gross-Ups. We do not have any arrangements requiring us to gross-up compensation to cover taxes owed by our executive officers, including excise taxes payable by the executives in connection with a change in control.
ü	Compensation Risk Assessment. The Compensation Committee conducted a compensation risk assessment to ensure that the executive compensation program does not encourage excessively risky behaviors.	û	No Dividends Equivalents on Unearned Performance Awards. We do not pay dividend equivalents with respect to performance-based awards unless and until the awards are earned, at which time each holder of an earned award will receive a catch-up cash payment equal to the aggregate amount of dividends that would have been paid in respect of our common shares underlying the award had such shares been issued to the holder on the first day of the performance period. Thereafter, dividend equivalents will be paid currently on earned awards.

Role of the Compensation Committee and Management

The Compensation Committee reviews and approves the corporate goals and objectives with respect to the compensation of the Company’s named executive officers on an annual basis. The Compensation Committee evaluates the performance of each named executive officer in light of these goals and objectives and, on the basis of such evaluation, determines and approves the compensation for each named executive officer. Our Chief Executive Officer makes recommendations to the Compensation Committee regarding the compensation of the named executive officers other than the Chief Executive Officer.

In determining the appropriate compensation for the Company’s named executive officers, the Compensation Committee considers the Company’s performance and shareholder return, the amount of compensation payable, including incentive awards, to similarly situated officers at comparable companies, our shareholder vote on compensation and any other factors the Compensation Committee deems necessary or appropriate in its discretion. The Compensation Committee seeks to ensure that our compensation plans are designed with an appropriate balance of risk and reward in relation to the Company’s overall business objectives and do not encourage excessive or unnecessary risk taking. In addition, the Compensation Committee seeks to ensure that our programs retain talented executives, encourage high performance, promote accountability and align our named executive officers’ interests with those of our shareholders.

Advisory Vote on Named Executive Officer Compensation

Our shareholders approved the compensation of our named executive officers in the non-binding advisory vote that we conducted at the 2024 annual meeting of shareholders, with approximately 70.1% of the votes cast in favor of this proposal.

Our shareholders also approved the compensation that may become payable by the Company to our named executive officers in connection with the Plan of Sale in the non-binding advisory vote that we conducted at the 2024 special meeting of shareholders, with approximately 86.7% of the votes cast in favor of this proposal. The Compensation Committee considered these voting results as supportive of our executive compensation philosophy.

The Role of the Compensation Consultant

Under its charter, the Compensation Committee has the sole authority to retain and terminate outside legal or other advisors to the Compensation Committee as it deems necessary and appropriate in its sole discretion, including compensation consultants. The Compensation Committee has engaged FPC to advise it on matters related to the compensation of our executive officers and our compensation plans. FPC is engaged by, and reports directly to, the Compensation Committee, which has the sole authority to retain or terminate the services of FPC and to approve the consultant’s fees and other retention terms. FPC provides no other services to the Company. The Compensation Committee has reviewed the independence of FPC in light of SEC rules and NYSE listing standards regarding compensation consultants, and the Compensation Committee has concluded that FPC’s work is independent and does not raise any conflict of interest.

The Compensation Committee has retained FPC to, among other things: (i) assist in benchmarking our executive compensation against our peers; (ii) analyze trends in compensation in the marketplace generally and compensation program design changes among our peers specifically; and (iii) provide general guidance with respect to appropriate compensation levels and structures.

Use of Benchmarking and Peer Group Data

The Compensation Committee uses peer group data as one tool in assessing and determining pay for our executive officers. Competitive market data is intended to provide a framework for current market pay practices, trends, best practices and overall industry performance.

Each year, the Company reviews its peer group based on a variety of factors and, in consultation with its compensation consultant, determines if any changes are appropriate. In connection with these efforts, a variety of factors were utilized to determine our peer group’s members, including: (1) REITs that are comparable to us based on size and (2) REITs that are comparable to us based on asset class (office).

As part of its ongoing compensation program review process, in September 2022, the Compensation Committee reviewed and revised the peer group it uses to make compensation decisions. The revised peer group was used to make compensation decisions beginning in early 2023 and has remained unchanged.

The following table contains the name of each company within the current peer group, all of which are public office REITs.

Elements of Compensation

Base Salary

We pay our named executive officers base salaries to provide them with a predictable and stable source of cash income in order to compensate them for performing the requirements of their respective positions and to retain and motivate them.

The Compensation Committee reviews each named executive officer’s base salary annually. Any adjustments to an executive’s base salary are based on the Compensation Committee’s evaluation of the executive’s performance and competitive pay. In determining the appropriate annual base salary for each named executive officer, the Compensation Committee considers the executive’s contribution to the Company, the Company’s shareholder return, the amount of compensation payable to similarly situated executives at comparable companies (including any increases in such compensation), any shareholder vote on compensation and any other factors that the Compensation Committee deems necessary or appropriate in its discretion.

Our named executive officers’ base salaries were unchanged from fiscal year 2020 through fiscal year 2022, with the exception of Mr. Griffiths who received a salary increase for fiscal year 2022 following his appointment to Chief Financial Officer effective April 1, 2021. On January 26, 2023, the Compensation Committee approved increases to the annual base salaries for each of the Company’s named executive officers in recognition of Company performance and individual performance, and also brought each named executive officer’s compensation in line with similarly situated executives at comparable companies. On January 29, 2024, the Compensation Committee approved a 4.0% increase in annual base salary for each of the Company’s named executive officers in line with the standard increase for the Company’s non-executive employees for fiscal year 2024. Base salaries for our named executive officers for fiscal years 2023 and 2024 are set forth below:

Named Executive Officer	2023 Base Salary	2024 Base Salary	Percentage Change in Base Salary
David A. Helfand	$950,000	$988,000	4%
William H. (Bill) Griffiths	$600,000	$624,000	4%
David S. Weinberg	$675,938	$702,975	4%
Orrin S. Shifrin	$594,825	$618,618	4%

Annual Cash Incentive Compensation

The Company’s named executive officers are eligible to receive annual cash bonuses under the Company’s short-term annual incentive program (the “STIP”) based on the achievement of certain performance criteria for the applicable fiscal year, as determined annually by the Compensation Committee based on the Company’s then-applicable business objectives. The purpose of the STIP is to encourage outstanding Company and individual performance by motivating the Company’s executives to achieve short-term Company and individual goals by rewarding performance measured against key annual objectives. STIP bonuses are paid 100% in cash.

In January 2024, as in past years, the Compensation Committee approved corporate and individual performance goals for determining the amount of cash bonuses to be awarded to our named executive officers for fiscal year 2024 under the STIP. In setting these goals in January 2024, the Compensation Committee determined that it was appropriate that (i) 67% of the annual bonus target under the 2024 STIP be based upon achievement of the corporate operational performance metrics listed below (with threshold, target and maximum values established by the Compensation Committee at what is believed to be appropriately rigorous and challenging levels for each metric), and (ii) 33% of the annual bonus target under the 2024 STIP be based upon achievement of individual objectives.

In January 2024, the Compensation Committee identified the following corporate performance metrics:

•Same Property Leased Occupancy – the Compensation Committee linked our named executive officers’ annual bonuses to this objective by quantifying their effectiveness in retaining and attracting tenants to the Company’s assets, which is captured in the measurement of same property leased occupancy; and

•Same Property Cash Net Operating Income – the Compensation Committee linked our named executive officers’ annual bonuses to this objective to measure their ability to impact the performance of our assets by capturing both rent fluctuations and whether expenses are being controlled.

In 2024, after the determination of the performance goals, the Board made the decision to approve and recommend to shareholders the Plan of Sale. In January 2025, in light of the shareholders’ approval and the Company’s implementation of the Plan of Sale, the Compensation Committee determined that the corporate operational performance metrics previously approved by the Compensation Committee in January 2024 no longer constituted valid measures of performance, because the Plan of Sale resulted in the sale in 2024 of three of the Company’s four remaining properties, as part of the planned liquidation of the Company. As a result, the Compensation Committee determined that the cash amounts to be awarded to the Company’s executive officers under the 2024 STIP should be determined in the discretion of the Compensation Committee based on the achievement of each executive officer’s applicable subjective performance goals as established by the Committee in January 2024.

The 2024 individual goals achieved by our named executive officers included the following:

•For Mr. Helfand, providing leadership to create value for all of our stakeholders, cultivating relationships with senior executives in the real estate and investment communities to raise the Company’s profile and maximize the potential for investment opportunities, leading the underwriting and evaluation of potential growth opportunities, facilitating effective board and senior management communication and teamwork, promoting a corporate culture grounded in our core values, nurturing a work environment where employees are challenged and rewarded for their success, providing leadership in connection with our sustainability and social responsibility initiatives, overseeing the evaluation of various potential wind-down strategies and implementing the Plan of Sale;

•For Mr. Griffiths, developing, motivating and providing effective oversight of our accounting, tax and treasury professionals and functions, facilitating effective communication with the Board, the Audit Committee and the Compensation Committee, actively managing the balance sheet, cultivating and improving relationships with institutional investors and analysts, continuing our sustainability and social responsibility initiatives, evaluating various potential wind-down strategies and implementing the Plan of Sale;

•For Mr. Weinberg, seeking out and evaluating potential acquisition opportunities, enhancing property valuations, overseeing efficient and effective capital allocation, managing and motivating our investment professionals, maximizing the value of dispositions, continuing our sustainability and social responsibility initiatives, evaluating various potential wind-down strategies and implementing the Plan of Sale; and

•For Mr. Shifrin, providing valuable legal advice on real estate, public market and transaction-related matters, proactively supporting property operations and leasing while promoting compliance with laws and regulations, facilitating effective board and senior management leadership with a high level of ethical integrity, including by maintaining a rigorous corporate governance and compliance environment, encouraging an effective risk management culture, continuing our sustainability and social responsibility initiatives, evaluating various potential wind-down strategies and implementing the Plan of Sale.

The threshold, target and maximum annual bonus amounts for our named executive officers under the STIP as determined at the beginning of the fiscal year 2024, as a percentage of their respective annual base salaries, were as follows:


Named Executive Officer	Threshold	Target	Maximum
David A. Helfand	75%	150%	225%
William H. (Bill) Griffiths	50%	100%	150%
David S. Weinberg	50%	100%	150%
Orrin S. Shifrin	50%	100%	150%

LTIC Program Awards

The LTIC Shares are scheduled to vest 25% on the “Measurement Date” (as defined below) in February of the calendar year during which the second anniversary of the grant date occurs, 25% on the Measurement Date in February of the calendar year during which the third anniversary of the grant date occurs and 50% on the Measurement Date in February of the calendar year during which the fourth anniversary of the grant date occurs, subject to the executive’s continued employment with the Company through the applicable vesting date. The term “Measurement Date” means either (i) the date in February of the applicable calendar year on which the Compensation Committee meets to determine the level of achievement of the performance criteria with respect to any performanceTime-~~based~~Based awards or, (ii) if there are no such awards for which performance is required to be measured during the applicable calendar year, the first date in February of such calendar year on which the Compensation Committee meets or takes an action by unanimous written consent. Each LTIC Share entitles the named executive officer to receive any dividends declared on our common shares beginning on the grant date of the LTIC Share. Awards

The resulting earned Performance-Based Awards, as well as the previously earned but unvested Performance-Based Awards, became fully vested and were settled in shares or in cash promptly following the date of the ~~applicable~~change ~~performance~~in ~~criteria~~control.

The primary performance measure for the LTIC RSUs is the TSR of our common shares over a three-year performance period relative to the TSRs of the companies that comprise the Nareit Office Index over the same period of time, provided that only companies that are public throughout the entire performance period will be included for purposes of calculating the relative TSR comparison. The secondary performance measure for the LTIC RSUs is absolute TSR if the Company’s TSR is negative.

After the Company’s TSR percentile is determined, the number of LTIC RSUs that will be earned by an executive will be determined by multiplying the number of units that was granted to the executive by the applicable percentage listed in the following table.

Company TSR Relative to Nareit Office Index TSRs over Performance Period			% of Granted LTICRSUs Earned*
90th Percentile and Above			249.5%
80th Percentile			212.0%
70th Percentile			174.5%
60th Percentile			137.0%
50th Percentile (Target)			100.0%
40th Percentile			68.5%
30th Percentile			37.5%
25th Percentile			25.5%
Below 25th Percentile			0.0%
* The actual number of LTIC RSUs earned will be the number of units awarded to each named executive officer, which is the target number of units that can be earned, multiplied by the applicable percentage listed in the table above. The actual number of LTIC RSUs will be determined at the end of the three-year performance period. The percentages listed in the table above are rounded to the nearest 0.5%.

If the Company’s total TSR for the performance period is negative, any LTIC RSUs deemed earned based on the table above will be reduced by 25%. To the extent performance falls between two levels in the table above, linear interpolation will apply in determining the percentage of the LTIC RSUs that are earned. Any LTIC RSUs that do not become earned at the end of the performance period will be forfeited.

The LTIC RSUs are scheduled to vest as follows: (i) 50% following the conclusion of the performance period on the date that the Compensation Committee determines whether and to what extent the performance criteria have been achieved, and (ii) 50% on the Measurement Date in February of the calendar year during which the fourth anniversary of the grant date occurs, subject in each case to the executive’s continued employment with the Company through such date.

The named executive officers will not be entitled to receive any dividends with respect to the common shares underlying the LTIC RSUs unless and until the LTIC RSUs are earned, at which time each executive will be entitled to receive an amount in cash equal to the aggregate amount of dividends that would have been paid in respect of the common shares underlying the executive’s earned LTIC RSUs had such common shares been issued to the executive on the first day of the performance period. Following the performance period, each executive will be entitled to receive, in respect of each earned LTIC RSU held by the executive, whether or not vested, an amount in cash equal to the per share amount of any dividend paid by the Company to the shareholders, which amount will be paid to the executive within 60 days following the date that the dividend is paid to the shareholders.

To the extent a named executive officer elects to receive his award under the LTIC Program in the form of LTIP Units, the named executive officer would receive an award consisting of (i) LTIP Units (equal to 33% of the target value of the LTIC Program award) subject to time-vesting requirements generally consistent with the vesting terms applicable to LTIC Shares (the “Time-Based LTIP Units”) and (ii) LTIP Units (equal to 67% of the target value of the LTIC Program award) subject to time-vesting and performance-vesting requirements generally consistent with the vesting terms applicable to LTIC RSUs (the “Performance-Based LTIP Units”). A Time-Based LTIP Unit generally entitles the holder thereof to receive the same per unit distributions as the other OP Units of the Operating Trust. A holder of Performance-Based LTIP Units will not be entitled to participate in distributions with respect to the executive’s Performance-Based LTIP Units until expiration of the applicable performance period, at which time the executive generally will become entitled to receive a special catch-up distribution in respect of the executive’s earned Performance-Based LTIP Units, if any, for the periods prior to such time.

Calculation of Three-Year Measurement for January 25, 2021 Performance-Based Awards. On February 6, 2024, the Compensation Committee approved the level of achievement of the performance measure with respect to the performance-based awards that were granted to our named executive officers on January 25, 2021. The Compensation Committee determined that the TSR of the Common Shares over the three-year performance period commencing on January 25, 2021 and ending on January 25, 2024, relative to the TSRs of the companies that comprised the Nareit Office Index over the same period of time, was in the 79th percentile. Accordingly, approximately 155.95% of the target performance-based awards granted to each executive became earned, inclusive of a 25% reduction because EQC’s absolute TSR for the performance period was negative (116,228, 7,955, 61,585, and 37,573 RSUs for Messrs. Helfand, Griffiths, Weinberg, and Shifrin, respectively). 50% of such earned performance-based awards vested on February 6, 2024, when the Compensation Committee approved the performance measurement, and 50% vested on February 4, 2025.

Calculation of Three-Year Measurement for January 26, 2022 Performance-Based Awards. On February 4, 2025, the Compensation Committee approved the level of achievement of the performance measure with respect to the performance-based awards that were granted to our named executive officers on January 26, 2022 (the “2022 Performance-Based Awards”). The Compensation Committee determined that the TSR of the common shares over the three-year performance period commencing on January 26, 2022 and ending on January 26, 2025, relative to the TSRs of the companies that comprised the Nareit Office Index over the same period of time, was in the 79th percentile. Accordingly, approximately 207.93% of the target 2022 Performance-Based Awards granted to each executive became earned (171,685, 22,401, 90,967, and 55,500 for Messrs. Helfand, Griffiths, Weinberg, and Shifrin, respectively).

In December 2024, as part of the Plan of Sale and to facilitate an efficient wind-down of the Company, the Company terminated its various Registration Statements on Form S-8 (the “S-8 Registration Statements”), which were used to register the Company’s common shares reserved for issuance as equity awards under the LTIC Program pursuant to the 2015 Omnibus Plan. As a result, the Company will not be able to issue additional shares under the 2015 Omnibus Plan with respect to the portion of any outstanding performance-based awards that is determined to be earned in light of above-target performance. Consequently, on January 27, 2025, the Compensation Committee amended the 2022 Performance-Based Awards granted to our employees who received January 26, 2022 Performance-Based Awards, including our named executive officers, to provide that such awards would be settled in cash as to the portion of the 2022 Performance-Based Awards measured above target, with 50% of such awards vesting on February 4, 2025, when the Compensation Committee approved the performance measurement, and 50% of such awards scheduled to vest on the Measurement Date in February of 2026, subject to the terms and conditions of the applicable award agreements.

The treatment of the LTIC Shares, Time-Based LTIP Units, LTIC RSUs and Performance-Based LTIP Units upon a termination of the executive’s employment and/or a change in control of the Company is described below in the section entitled “Potential Payments Upon Termination or Change in Control.”

Severance Rights and Change in Control Agreements

The Company entered into Change in Control Agreements (each, a “CIC Agreement”) in April 2019 with Messrs. Helfand, Weinberg and Shifrin and in August 2022 with Mr. Griffiths which are described below in the section entitled “Change in Control Agreements.” The Company is not a party to any other type of employment agreements with any of the named executive officers. The CIC Agreements provide that the Company will provide accelerated vesting for all or a portion of the named executive officers’ outstanding equity awards and a prorated bonus payment upon certain terminations of employment, as described below in the section entitled “Potential Payments Upon Termination or Change in Control.” Additionally, in June 2023, the Board and the Compensation Committee updated the Company’s severance practices for employees of the Company, including the named executive officers, to provide for certain payments in the event of certain qualified terminations as described in the section below entitled “Potential Payments Upon Termination or Change in Control.”

Other Employee Benefits and Perquisites

We provide to all our employees, including our named executive officers, market health and welfare benefits that are intended to help attract and retain employees, including life and health benefits and vacation, holiday and sick time. We do not provide executive perquisites to our named executive officers.

Other Compensation Practices and Policies

Stock Ownership Guidelines

We believe that equity ownership by our officers helps align their interests with our shareholders’ interests. To that end, we have adopted formal stock ownership guidelines applicable to all of our named executive officers with the following key terms:

• Our Chief Executive Officer is required to own our securities equal in value to at least six times his base salary based on the average annual closing price of the Company’s common shares;

• Each of our other named executive officers is required to own our securities equal in value to at least three times the executive's base salary based on the average annual closing price of the Company’s common shares;

• We do not include unmeasured or unvested performance-based awards in our executive ownership calculations;

• Each named executive officer has five years to comply with the ownership requirement and is required to hold shares at this level while serving in his position; and

• Mandatory holding period that requires named executive officers to retain all net securities (after payment of applicable taxes) earned from any equity award until the applicable stock ownership requirement is achieved.

All of our named executive officers are in compliance with our stock ownership guidelines as of the date of this Annual Report on Form 10-K. See the section below entitled “Trustee Compensation – Stock Ownership Guidelines” for a discussion of the stock ownership guidelines applicable to non-employee trustees.

Anti-Hedging and Anti-Pledging Policies

Our Board has adopted restrictions on hedging and pledging securities issued by the Company pursuant to the Company’s Policy on Inside Information and Insider Trading. With respect to hedging, our trustees, employees (including executive officers) and their family members who reside with them are prohibited from trading in any interest relating to the future price of the Company’s securities, such as a put, call or short sale. With respect to pledging, trustees, employees (including executive officers) and their family members who reside with them are prohibited from holding securities issued by the Company in a margin account or pledging these securities as collateral for a loan. The Board may grant exceptions to this anti-pledging policy for trustees and executive officers and the Company’s Compliance Officer may grant such exceptions to other employees. No such exceptions have been granted for trustees, executive officers or their family members since the implementation of the policy on July 31, 2014.

Tax Deductibility of Executive Compensation

Under Section 162(m) of the Code, a publicly-held corporation (including the Company) generally is limited to a $1 million annual tax deduction for compensation paid to each of its “covered employees,” which limitation would apply to the Company to the extent the real estate investment trust’s distributive share of any compensation paid to its covered employees by our operating partnership exceeds the $1 million threshold (other than compensation attributable to certain grandfathered equity grants).

While the Compensation Committee will consider the impact of Section 162(m) on its compensation arrangements going forward, it is only one of many factors, and it is anticipated that Compensation Committee will, in its discretion and when it deems appropriate, enter into compensation arrangements with those executives considered “covered employees” under which payments may not be fully deductible under Section 162(m).

Clawback Policy

The Compensation Committee adopted a clawback policy in 2014, which has been modified from time to time, including most recently in October 2023, when the Compensation Committee amended the clawback policy to comply with the finalized and effective SEC and NYSE rules (Section 10D of the Exchange Act, Rule 10D-1 of the Dodd Frank Wall Street Reform and Consumer Protection Act promulgated thereunder, and Section 303A.14 of the NYSE Exchange Listed Company Manual). Pursuant to the amended clawback policy, in the event of an accounting restatement (“Accounting Restatement”), the Company’s current or former named executive officers and certain other officers (as defined in the clawback policy) must reimburse the Company for (i) any incentive-based compensation erroneously awarded during the three completed fiscal years preceding the date on which the Company is required to prepare such Accounting Restatement, and (ii) any profits realized from the sale of the Company’s securities during the period following the first public issuance or filing with the SEC of the misstated financials. Incentive compensation subject to recoupment, includes the difference between the amount of incentive

compensation received by the individual during the three fiscal years preceding the required Accounting Restatement and the amount that the individual would have received based on the restated financial measures. For incentive compensation based on the price of shares of our common shares or total shareholder return, the Company will determine an amount that is a reasonable estimate of the effect of the Accounting Restatement on our common share price for the relevant period. The Compensation Committee has the authority to interpret and make all determinations under the amended clawback policy.

Equity Award Grant Practices

Our annual equity awards are approved by the Compensation Committee in January each year. We do not manipulate either the timing of the release of material nonpublic information or the timing of the grant of an equity award with the intent of benefiting any grantee, and we have not timed the disclosure of material nonpublic information for the purposes of affecting the value of executive compensation. Accordingly, no equity awards were granted to our named executive officers within four business days prior to or one business day following the filing of a Form 10-Q, 10-K, or 8-K that disclosed material nonpublic information during 2024.

2025 Compensation Actions

2025 Base Salaries

On January 27, 2025, the Compensation Committee approved a 3% increase in annual base salary for each of our named executive officers in line with the standard increase for the Company’s non-executive employees for fiscal year 2025. Base salaries for the Company’s named executive officers for fiscal years 2024 and 2025 are set forth below:

Named Executive Officer	2024 Base Salary	2025 Base Salary	Percentage Change in Base Salary
David A. Helfand	$988,000	$1,017,640	3%
William H. (Bill) Griffiths	$624,000	$642,720	3%
David S. Weinberg	$702,975	$724,064	3%
Orrin S. Shifrin	$618,618	$637,177	3%

2025 STIP Performance Goals

On January 27, 2025, the Compensation Committee determined that, in light of the Plan of Sale and the wind-down of the Company resulting in the sale in 2024 of three of the Company’s four remaining properties, the STIP for fiscal year 2025 will be determined in the discretion of the Compensation Committee based on the achievement of pre-determined subjective corporate and individual performance goals. The threshold, target and maximum annual bonus amounts under the STIP for fiscal year 2025, as a percentage of their respective annual base salaries, remain the same as the corresponding amounts for fiscal year 2024 for Messrs. Helfand, Griffiths, Weinberg and Shifrin, with such amounts set as follows: 75%, 150% and 225%, respectively, for Mr. Helfand; and 50%, 100% and 150%, respectively, for each of Messrs. Griffiths, Weinberg and Shifrin.

2024 LTIC Program Awards

Since the current Board and management team took over in 2014, the Company has adopted an annual LTIC Program that has remained relatively unchanged through the LTIC awards granted on January 29, 2024. In December 2024, as part of the Plan of Sale and to facilitate an efficient wind-down of the Company, the Company terminated its various S-8 Registration Statements, which were used to register the Company’s common shares reserved for issuance as equity awards pursuant to the 2015 Omnibus Plan. As a result, the Company will not be able to issue new equity awards under the 2015 Omnibus Plan. Consequently, on January 27, 2025, in lieu of equity awards, the Compensation Committee approved the grant of cash-based awards under the LTIC Program (“LTIC Cash Awards”) to our employees who are eligible to receive long-term incentive compensation as part of their annual compensation package, including our named executive officers, for service in fiscal year 2024, subject to same vesting requirements as the LTIC Shares.

The 2024 LTIC Program awards that were granted by the Compensation Committee to each named executive officer in January 2025, under the 2015 Omnibus Plan are set forth below:

Named Executive Officer			LTIC Cash Awards
David A. Helfand			$3,681,080
William H. (Bill) Griffiths			$832,000
David S. Weinberg			$1,818,239
Orrin S. Shifrin			$1,109,306

The LTIC Cash Awards granted in January 2025 have the same vesting terms and conditions as the LTIC Shares granted in January 2024, as described above in the section entitled “Compensation Discussion and Analysis – Elements of Compensation – Long-Term Incentive Compensation.” The treatment of the LTIC Cash Awards granted in January 2025 upon a termination of the executive’s employment or a change in control of the Company is the same as the treatment of the LTIC Shares granted in January 2024 in such circumstances, as described below in the section entitled “Potential Payments Upon Termination or Change in Control.”

Compensation Committee Report

The Compensation Committee has reviewed and discussed the Compensation Discussion and Analysis required by Item 402(b) of Regulation S-K with management. Based on such review and discussions, the Compensation Committee recommended to the Board that the Compensation Discussion and Analysis be included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2024.

Respectfully submitted, THE COMPENSATION COMMITTEE Gerald A. Spector, Chair Peter Linneman James A. Star

1 The amount in the “Target” column represents the number of LTIC RSUs granted to Messrs. Helfand, Griffiths, Weinberg and Shifrin on January 29, 2024, and is the target number of LTIC RSUs that the executive may earn under the award. The LTIC RSUs are market-based grants that will be earned based upon the Company’s TSR relative to the TSRs of the companies that comprise the Nareit Office Index over a three-year performance period, with any earned LTIC RSUs vesting 50% following the performance period and 50% on the Measurement Date in February of the calendar year during which the fourth anniversary of the date of grant occurs. The executive will earn between 0% and 249.25% of the number of the LTIC RSUs granted to him depending on the achievement of the performance criteria over the performance period. The executive will earn the target number of LTIC RSUs if the Company’s relative TSR performance over the three-year performance period is in the 50th percentile. The amount in the “Maximum” column represents the number of LTIC RSUs that the executive will earn if the Company’s relative TSR performance over the three-year performance period is in the 90th percentile, which is the maximum number of LTIC RSUs that the executive may earn under the award. The amount in the “Threshold” column represents the number of LTIC RSUs that the executive will earn if the Company’s relative TSR performance over the three-year performance period is in the 25th percentile, which is the minimum level of performance that will still result in a portion of the LTIC RSUs being earned by the executive (none of the LTIC RSUs will be earned if performance is below the 25th percentile).

2 Reflects the number of LTIC Shares granted to Messrs. Helfand, Griffiths, Weinberg and Shifrin on January 29, 2024. The LTIC Shares vest 25% on the Measurement Date in February of the calendar year in which the second anniversary of the grant date occurs, 25% on the Measurement Date in February of the calendar year in which the third anniversary of the grant date occurs, and 50% on the Measurement Date in February of the calendar year in which the fourth anniversary of the grant date occurs.

Narrative Disclosure to Summary Compensation Table and Grants of Plan-Based Awards Table

EQC may provide long-term incentive compensation to employees, trustees, officers, consultants and advisors of the Company and its subsidiaries pursuant to the 2015 Omnibus Plan. The purpose of the 2015 Omnibus Plan was to provide eligible persons with an incentive to contribute to the success of the Company and to operate and manage the Company’s business in a manner that will provide for the Company’s long-term growth and profitability to benefit its shareholders and other important stakeholders, including its employees and customers, and provide a means of obtaining, rewarding and retaining key personnel. The 2015 Omnibus Plan is administered by the Compensation Committee, which has the authority to select persons to whom awards will be granted and to determine the terms and conditions of such awards. The following types of awards may be granted under the 2015 Omnibus Plan, subject to the limitations set forth in the 2015 Omnibus Plan: stock options; stock appreciation rights; restricted stock; stock units; unrestricted stock; dividend equivalent rights; performance shares and other performance-based awards; limited partnership interests in the partnership entity through which the Company conducts its business; other equity-based awards; and cash awards. While historically awards granted under the 2015 Omnibus Plan were equity awards, following the Company’s December 2024 termination of its S-8 Registration Statements as part of the Plan of Sale and wind-down of the Company, awards will be cash based.

The key terms of the LTIC Shares and LTIC RSUs granted to the named executive officers on January 29, 2024, which were granted under the 2015 Omnibus Plan, are described above in the section entitled “Compensation Discussion and Analysis – Elements of Compensation – Long-Term Equity Compensation.”

David A. Helfand	150,574	2,842,837
William H. (Bill) Griffiths	11,554	218,140

2 The value realized upon vesting equals the closing market price of our common shares on the date of vesting ($18.88 on February 6, 2024) multiplied by the number of shares/LTIPs vested.

Potential Payments Upon Termination or Change in Control

The LTIC Program awards granted to the named executive officers, the key terms of which are described above in the section entitled “Compensation Discussion and Analysis – Elements of Compensation – Long-Term Equity Compensation,” provide for the accelerated vesting of the awards in the event of certain terminations of employment from or a change in control of the Company, as described below. Our Board determined that a Change in Control occurred on February 25, 2025 as a result of the sale of 1225 Seventeenth Street Plaza, which it determined constituted a sale of substantially all of our assets. As described in the section below entitled “Change in Control Agreements” the named executive officers are each party to a CIC Agreement. Additionally, in June 2023, in recognition of the fact that the Company’s STIP bonus payments are paid and LTIC Program grants are made in arrears for each employee’s service and performance during the year preceding the year of payment or grant, the Board and the Compensation Committee each approved that employees of the Company, including the named executive officers, will be entitled to certain prorated bonus payments in the event of a Qualified Termination, as described below. For purposes of the severance benefits described below, a “Qualified Termination” means the named executive officer’s employment is terminated (i) by the Company or an affiliate without Cause (as such term is defined in the 2015 Omnibus Plan); (ii) by the named executive officer for “good reason” (as such term is defined in the applicable equity award agreement); (iii) due to the named executive officer’s “retirement” (as such term is defined in the applicable equity award agreement); or (iv) due to the named executive officer’s death or “disability” (as such term is defined in the 2015 Omnibus Plan).

LTIC Program Awards – LTIC Shares, Time-Based LTIP Units and LTIC Cash Awards

As described above in the section entitled “Compensation Discussion and Analysis – Elements of Compensation – Severance and Change in Control Benefits,” in the event of a named executive officer’s Qualified Termination, the executive’s unvested LTIC Shares, Time-Based LTIP Units and LTIC Cash Awards, as applicable, will become fully vested as of the date of termination. If the executive’s Qualified Termination occurs within twelve months after a “Change in Control” (as such term is defined in the equity awards agreements), in which the LTIC Shares, Time-Based LTIP Units and LTIC Cash Awards are assumed by the acquirer or surviving entity in the Change in Control transaction, then the executive’s unvested LTIC Shares, Time-Based LTIP Units and LTIC Cash Awards, as applicable, will become fully vested on the date of termination.

If a Change in Control occurs prior to the fourth anniversary of the grant date and while the executive is an employee of the Company, and the LTIC Shares, Time-Based LTIP Units and LTIC Cash Awards are not assumed by the acquirer or surviving entity in the Change in Control transaction, then the executive’s unvested LTIC Shares, Time-Based LTIP Units and LTIC Cash Awards, as applicable, will become fully vested as of the date of the Change in Control.

Each Time-Based LTIP Unit and earned Performance-Based LTIP Unit will convert automatically into an OP Unit on a one-for-one basis when the LTIP Unit becomes vested and upon a Book-Up Event. Holders of OP Units (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, our common shares on a one for one basis.

LTIC Program Awards – LTIC RSUs and Performance-Based LTIP Units

If, during the performance period, the named executive officer’s employment with the Company is terminated as a result of a Qualified Termination that is not in connection with a Change in Control, then the number of LTIC RSUs and Performance-Based LTIP Units, as applicable, will remain eligible to become earned based on the actual level of achievement

of the applicable performance criteria, as determined by the Compensation Committee at the end of the applicable performance period. The earned portion of such awards, if any, will be considered vested as of the date the Compensation Committee determines the achievement of the applicable performance criteria.

If the executive’s Qualified Termination occurs during the performance period and within twelve months after a Change in Control in which the LTIC RSUs and Performance-Based LTIP Units were assumed by the acquirer or surviving entity in the Change in Control transaction, then any LTIC RSUs and Performance-Based LTIP Units that become earned after the end of the performance period will become fully vested as of the date the Compensation Committee determines the achievement of the performance criteria. Also, in this case, with respect to any earned LTIC RSUs and Performance-Based LTIP Units, as applicable, held by the named executive officer for which the performance period is complete but for which the additional vesting period is incomplete prior to the executive’s Qualified Termination, such earned LTIC RSUs and Performance-Based LTIP Units, as applicable, will become fully vested as of the date of the executive’s Qualified Termination.

If, during the performance period, a Change in Control occurs while the named executive officer is an employee of the Company and the LTIC RSUs and Performance-Based LTIP Units are not assumed by the acquirer or the surviving entity in the Change in Control transaction, then the executive’s LTIC RSUs and Performance-Based LTIP Units, as applicable, will be deemed earned based on the actual level of achievement of the performance criteria measured as of the date of the Change in Control, as determined by the Compensation Committee based on the 40-day trailing average price per common share. Any such earned LTIC RSUs and Performance-Based LTIP Units will be fully vested. In this case, with respect to any earned LTIC RSUs and Performance-Based LTIP Units, as applicable, held by the executive for which the performance period is complete but for which the additional vesting period is incomplete at the time of the Change in Control, such earned LTIC RSUs and Performance-Based LTIP Units, as applicable, will become fully vested as of the date of the Change in Control.

Under the CIC Agreements, upon a ~~termination~~qualifying of the employment of a named executive officer by the Company without Cause (excluding by reason of the executive’s death or disability) or by the named executive officer for Good Reason (as such defined terms are set forth belowtermination, ~~and consistent with~~ the definitions of such terms in the 2015 Omnibus Plan and the equity award agreements issued under such plan) (each a “CIC Termination”) that occurs (i) within the six-month period prior to or two-year period following a Change in Control; or (ii) at any time, if in connection with or in anticipation of a Change in Control, the applicable named executive officer ~~will~~became be entitled to~~, subject to his execution and delivery of an irrevocable release of claims against the Company~~: (i) a lump sum payment equal to three times the sum of (x) ~~the~~ ~~named~~his ~~executive officer’s~~ annual base salary (at the rate in effect as of the date of termination, ~~or, if greater, as of the date of the Change in Control (as applicable)),~~ and (y) the two-year average of ~~the~~his most recently earned STIP awards; (ii) a lump sum payment equal to ~~the~~his most recently earned STIP award multiplied by a fraction, the numerator of which is the number of days the named executive officer iswas employed ~~by the Company~~ during the year in which termination occurs and the denominator of which is 365 (the “Prorated Bonus”); and (iii) a lump sum payment equal to the amount that would have been payable ~~by the Company~~ for the cost of continued family coverage under the Company’s medical plan for a specified period following the date of termination (36 months for Mr. Helfand and 24 months for the other ~~applicable~~ named executive officers). The ~~applicable~~severance benefits were subject to each named executive officer’s ~~will~~execution ~~also~~and bedelivery of an irrevocable release of claims, which was provided in each case. The named executive officers were also entitled to receive any accrued benefits (which ~~will~~were not be subject to a release), ~~including,~~as ~~without~~well ~~limitation,~~as ~~any~~regular ~~unpaid~~salary ~~STIP~~payment ~~award~~through ~~for~~ the ~~year~~date ~~prior~~that all work to wind down the ~~year~~affairs inof ~~which~~the ~~termination~~Liquidating ~~occurs~~Trust was completed.

The cash severance payment is included above in the ~~Company~~“Summary ~~pays~~Compensation ~~STIP~~Table ~~bonuses~~for to2025 ~~active~~Fiscal ~~employees~~Year” in the “All Other Compensation” column.

InPursuant ~~addition,~~to the CIC Agreements ~~provide that~~, ~~in the event the applicable named executive officer experiences~~ a CIC Termination in connection with or in anticipation of, or within the two-year period following, a Change in Control in which the then-outstanding equity awards are assumed, the awards will be treated as follows: (i) any awards subject to solely time vesting (“~~Time~~best-~~Based Awards~~net”) ~~will~~cutback ~~become~~provision ~~fully~~was ~~vested~~applicable asif ~~of the date of termination; and (ii)~~ any ~~awards~~payment ~~subject~~made to ~~performance~~the ~~vesting~~named ~~(“Performance-Based~~executive ~~Awards”)~~officers ~~will~~in ~~remain~~connection ~~outstanding~~with ~~and~~a ~~eligible~~change toin ~~become~~control ~~earned at the end~~ of the ~~applicable~~Company, ~~performance~~including ~~period~~but ~~based~~not onlimited ~~achievement~~to ofany ~~the~~payment ~~applicable~~under ~~performance criteria, as determined by~~ the ~~Compensation~~CIC ~~Committee~~Agreements, ~~with~~would ~~any~~result ~~such~~in ~~earned~~an ~~awards~~excise ~~becoming~~tax ~~fully~~imposed ~~vested~~by asSection of4999 ~~the date~~ of ~~such determination and settled in accordance with~~ the ~~terms~~Internal ofRevenue ~~the~~Code, ~~applicable~~meaning ~~award agreements.

Pursuant to the CIC Agreements, a “best-net” cutback provision will be applied if any payment made to the applicable named executive officer in connection with a Change in Control, including but not limited to any payment under the CIC Agreement, would result in an excise tax imposed by Section 4999 of the Internal Revenue Code, meaning that the named executive officer will either: (i) receive all the payments and benefits to which he is entitled, subject to the excise tax; or (ii) have such payments and benefits reduced by the minimum amount necessary so that the excise tax would not apply, if such reduction would result in a greater net after-tax benefit to the named executive officer. In addition, the CIC Agreements provide that the named executive officer is subject to a perpetual confidentiality covenant.

For purposes of the CIC Agreements, “Cause” means: (i) the named executive officer’s conviction of, or plea of guilty or no contest to, a felony or a crime involving moral turpitude or the commission of any other act by him involving willful malfeasance or material fiduciary breach with respect to the Company or an affiliate of the Company; (ii) the named executive officer’s gross negligence or willful misconduct in connection with the performance of his duties to the Company; (iii) a material breach by the named executive officer of any term of any employment, consulting or other services, confidentiality, intellectual property or non-competition agreements, if any, between him and the Company or an affiliate of the Company; or (iv) a material violation by the named executive officer of state or federal securities laws.

For purposes of the CIC Agreements, “Good Reason” means the occurrence of one or more of the following without the named executive officer’s express written consent, which circumstances are not remedied by the Company within 30 days of its receipt of a written notice from the named executive officer describing the applicable circumstances giving rise to Good Reason (which notice must be provided by the named executive officer within 90 days of the named executive officer’s knowledge of the applicable circumstances); provided, however, that in order for the named executive officer to terminate his employment for Good Reason, the named executive officer must terminate employment within 60 days following the end of the Company’s cure period if the circumstances giving rise to Good Reason have not been cured: (i) any material, adverse change in the named executive officer’s duties, responsibilities, authority, title, status or reporting structure; (ii) a material reduction in the named executive officer’s base salary or bonus opportunity; or (iii) a geographical relocation of the named executive officer’s principal office location by more than 50 miles.

Prorated Bonus Payments

InEach ~~the event of a~~ named executive officer’s ~~Qualified~~was ~~Termination, the executive is~~ entitled to and received a cash payout of certain bonuses in recognition of ~~any~~the partial year of service during the year in which ~~the~~their qualifying termination ~~occurs~~occurred (i.e., 2025), as provided for under the CIC Agreements as well as a policy previously approved by the Company’s Compensation Committee and Board relating to each employee, including the named executive officers. The prorated bonus payment ~~equals~~equaled (i) the sum of the named executive officer’s STIP bonus actually paid for last completed calendar year prior to the year in which the ~~Qualified~~qualifying ~~Termination~~termination occurred (i.e., 2024), and the named executive officer’s LTIC Program target for the calendar year in which the ~~Qualified~~qualifying ~~Termination~~termination occurred (i.e., 2025), multiplied by (ii) a fraction, the numerator of which is the number of days in the year of the ~~Qualified~~qualifying ~~Termination~~termination through the named executive officer’s employment termination date and the denominator of which is 365. This prorated bonus payment iswas made in recognition of the fact that our STIP bonus payments ~~are~~were paid and LTIC Program grants ~~are~~were made in arrears for each employee’s service and performance during the year preceding the year of payment or grant. The ~~right~~STIP toBonus ~~receive~~is represented in the ~~prorated~~“Summary ~~bonus~~Compensation ~~payment~~Table isfor ~~subject~~2025 toFiscal Year” in the ~~impacted~~“Bonus” ~~named~~column ~~executive~~as ~~officer’s~~the ~~execution~~2025 STIP bonus payment, and ~~non-revocation~~the ofLTIC aProgram ~~release~~portion ofis ~~claims~~represented in athe ~~form~~“Summary ~~acceptable~~Compensation toTable ~~the~~for ~~Company.~~2025 ~~The~~Fiscal ~~prorated~~Year” ~~bonus~~in ~~payment~~the ~~will~~“All ~~not~~Other ~~result~~Compensation” incolumn (along with the ~~duplication~~cash ofseverance ~~the~~amount ~~prorated~~received). ~~STIP~~The prorated bonus payment ~~due~~was ~~under~~subject ~~the~~to each named executive ~~officers~~officer’s ~~CIC~~execution ~~Agreements~~and delivery of an irrevocable release of claims against the Company, which were provided.

Quantification of Payments

The following table sets forth quantitative information with respect to potential payments to each of the named executive officers or their beneficiaries upon a termination of employment from and/or a change in control of the Company in various circumstances as described above, assuming a termination of employment from and/or a change in control of the Company occurred, in each case, on December 31, 2024, which was the last business day of fiscal year 2024. The amounts reported are based on the closing market price per common share as of December 31, 2024 ($1.77). The amounts included in the table below do not include amounts otherwise due and owing to each applicable named executive officer, such as salary, the prior year’s annual bonus, or payments or benefits generally available to all salaried employees of the Company.

1 With respect to the amounts in the column entitled “Termination not in connection with a Change in Control,” we assumed that no Change in Control transaction occurred and a Qualified Termination occurred.

2 With respect to the amounts in the column entitled “Termination in connection with a Change in Control (Awards Assumed),” we assumed that the LTIC Shares and LTIC RSUs were assumed by the acquirer or surviving entity in the Change in Control transaction and a CIC Termination occurred within six months prior or two years following, or in connection with or anticipation of, a Change in Control.

3 With respect to the amounts in the column entitled “Change in Control without Termination (Awards not Assumed),” we assumed that the LTIC Shares and LTIC RSUs were not assumed by the acquirer or surviving entity in the Change in Control transaction.

4 With respect to the amounts in the column entitled “Change in Control without Termination (Awards Assumed),” we assumed that the LTIC Shares and LTIC RSUs were assumed by the acquirer or surviving entity in the Change in Control transaction.

5 In the event of a Qualified Termination not in connection with a Change in Control, the named executive officers would be entitled to the prorated bonus payments described in the section entitled “Executive Compensation – Potential Payments Upon Termination or Change in Control– Prorated Bonus Payments” above (calculated for this purpose based on the full bonus payable for 2024). In the event of a CIC Termination that occurs (i) within the six-month period prior to or two-year period following a Change in Control or (ii) at any time, if in connection with or in anticipation of a Change in Control, the named executive officers are entitled to cash severance equal to three times the executive’s current annual salary, three times the average STIP bonus for 2024 and 2023, a pro-rata portion of the STIP bonus and LTIC Program target for calendar year 2024 (calculated for this purpose based on the full bonus payable for 2024) and two years of continuation of healthcare benefits, except Mr. Helfand who receives three years of healthcare continuation.

6 For purposes of the “Termination not in connection with a Change in Control” and “Termination in connection with a Change in Control (Awards Assumed)” columns in the table above we assumed: (i) 100% of the earned LTIC RSUs, granted to the executives on January 25, 2021 that were measured on February 6, 2024 fully vested, and (ii) 100% of the LTIC RSUs granted to the executives on January 26, 2022, January 26, 2023 and January 29, 2024, respectively, will be earned at the end of the three-year performance period, which is the number of LTIC RSUs that the executives will earn if the target level of performance is achieved. For unearned LTIC RSUs the actual number of such awards that would be earned will be determined at the end of the performance period based on the achievement of the performance criteria. In the circumstance in which there is a Change in Control but no termination, and the LTIC RSUs are not assumed by the acquirer or surviving entity in the Change in Control transaction, the LTIC RSUs will be deemed earned based on the actual level of achievement of the performance criteria measured as of the date of the Change in Control and any earned LTIC RSUs will become fully vested. Accordingly, for purposes of the “Change in Control without Termination (Awards not Assumed)” column, assuming a Change in Control occurred on December 31, 2024 and based on performance measured as of such date, the LTIC RSUs granted in 2023 would be deemed earned at the target level of performance, the LTIC RSUs granted in 2022 and 2024 would be deemed earned between the target and maximum levels of performance and the unvested LTIC RSUs granted in 2021 would be earned at their measured level of performance, and all such earned LTIC RSUs would become fully vested.

Pay Ratio Disclosure

Pursuant to Item 402(u) of Regulation S-K and Section 953(b) of the Dodd-Frank Act, presented below is the ratio of the annual total compensation of our Chief Executive Officer to the annual total compensation of our median employee (excluding our Chief Executive Officer). The ratio presented below is a reasonable estimate calculated in a manner consistent with Item 402(u).

In identifying our median employee, we calculated the annual total cash compensation earned by each of our employees for the year ended December 31, 2024, excluding our Chief Executive Officer. Total cash compensation for these purposes included base salary and bonus, and was calculated using internal payroll records. We selected the median employee based on the 22 employees who were employed by us as of November 1, 2024, excluding our Chief Executive Officer, as determined under Item 402 of Regulation S-K (“Item 402 Compensation”).

The 2024 Item 402 Compensation for our Chief Executive Officer was $7,638,107. The 2024 Item 402 Compensation for our median employee was $440,037. The ratio of our Chief Executive Officer’s Item 402 Compensation to our median employee’s Item 402 Compensation for fiscal year 2024 is 17 to 1.

The SEC rules for identifying the median employee allow companies to adopt a variety of methodologies, to apply certain exclusions, and to make reasonable estimates and assumptions that reflect their compensation practices. As such, the pay ratio reported by other companies may not be comparable to our pay ratio reported above, as other companies may have different employment and compensation practices and may use different methodologies, exclusions, estimates and assumptions in calculating their own pay ratios.

Indemnification

The Maryland statute governing a REIT formed under the laws of Maryland, or the Maryland REIT law, permits a Maryland REIT to include in its charter a provision limiting the liability of its trustees and officers to the trust and its shareholders for money damages except for liability resulting from (i) actual receipt of an improper benefit or profit in money, property or services or (ii) active and deliberate dishonesty that is established in a judgment and is material to the cause of action. ~~Our~~EQC’s Declaration of Trust ~~includes~~included provisions limiting the liability of ~~our~~its trustees and officers for any debt, claim, demand, judgement decree, liability or obligation of any kind (in tort, contract or otherwise) of, against or with respect to the Company or arising out of any action take or omitted for or on behalf of the Company. ~~Our~~EQC’s Declaration of Trust further ~~provides~~provided that no trustee, officer, employee or agent of the Trust shall be liable to the Company, the shareholders or any other person for any act or omission except for his or her own willful misfeasance, bad faith, gross negligence or reckless disregard of duty.

The Maryland REIT Law permits a Maryland REIT to indemnify and advance expenses to its trustees, officers, employees and agents to the same extent as permitted by the Maryland General Corporation Law for directors, officers, employees and agents of Maryland corporations. The Maryland General Corporation Law (“MGCL”) permits a corporation to indemnify its present and former directors and officers, among others, against judgments, penalties, fines, settlements and reasonable expenses actually incurred by them in connection with any proceeding to which they were, may be, or threatened to be, a party by reason of their service in those or other capacities unless it is established that:

• the act or omission of the director or officer was material to the matter giving rise to the proceeding and (1) was committed in bad faith or (2) was the result of active and deliberate dishonesty;

• the director or officer actually received an improper personal benefit in money, property or services; or

• in the case of any criminal proceeding, the director or officer had reasonable cause to believe that the act or omission was unlawful.

However, under the MGCL, a Maryland corporation may not indemnify a director or officer for an adverse judgment in a suit by or in the right of the corporation or if the director or officer was adjudged to be liable to the corporation on the basis that a personal benefit was improperly received, unless in either case a court orders indemnification, and then only for expenses.

In addition, the MGCL permits a corporation to advance reasonable expenses to a director or officer upon the corporation’s receipt of:

• a written affirmation by the director or officer of his or her good faith belief that he or she has met the standard of conduct necessary for indemnification by the corporation; and

• a written undertaking by the director or officer or on the director’s or officer’s behalf to repay the amount paid or reimbursed by the corporation if it is ultimately determined that the director or officer did not meet the standard of conduct.

58EQC’s Declaration of Trust and bylaws obligated us, to the fullest extent permitted by Maryland law, to indemnify and to pay, reimburse or advance reasonable expenses to:

~~Our~~• any ~~Declaration~~then-current ofor ~~Trust~~former ~~and~~trustee ~~bylaws~~or ~~obligate~~officer ~~us,~~who towas ~~the~~made ~~fullest~~or ~~extent~~threatened ~~permitted~~to bybe ~~Maryland~~made ~~law,~~a party to ~~indemnify~~a ~~and~~proceeding toby ~~pay,~~reason ~~reimburse~~of his or ~~advance~~her ~~reasonable~~service ~~expenses~~in ~~to:~~that capacity; or

• any individual who, while a trustee or officer of our company and at our request, serves or has served as a trustee, officer or partner of another corporation, REIT, limited liability company, partnership, joint venture, trust, employee benefit plan or any other enterprise and who is made or threatened to be made a party to the proceeding by reason of his or her service in that capacity.19

~~Our~~or ~~Declaration~~any ofother ~~Trust~~enterprise and ~~bylaws~~who ~~also~~was ~~permit~~made ~~us,~~or ~~with~~threatened ~~the approval of our Board,~~ to ~~indemnify~~be ~~and~~made ~~advance~~a ~~expenses~~party to ~~any person who served a predecessor of ours in any of~~ the ~~capacities~~proceeding ~~described~~by inreason ~~our Declaration~~ of ~~Trust~~his ~~and bylaws and to any employee~~ or ~~agent~~her ofservice ~~our~~in ~~company or a predecessor of our company. Our bylaws specify~~ that ~~any indemnification or payment or reimbursement of the expenses as described above will be made in accordance with the procedures provided by the MGCL for directors of Maryland corporations~~capacity.

EQC’s Declaration of Trust and bylaws also permitted us, with the approval of its Board, to indemnify and advance expenses to any person who served a predecessor of EQC in any of the capacities described in the Declaration of Trust and bylaws and to any employee or agent of the Company or a predecessor of the Company. EQC’s bylaws specified that any indemnification or payment or reimbursement of the expenses as described above would be made in accordance with the procedures provided by the MGCL for directors of Maryland corporations.

The Liquidating Trust Agreement of EQC LT provides that no trustee of EQC LT shall be personally liable to any person in connection with EQC LT's assets or its affairs except for misconduct intentionally committed in bad faith and that no trustee shall be liable for any error of judgment made in good faith. The Liquidating Trust Agreement of EQC LT also provides and that each trustee and each of the employees and agents appointed or employed by the trustees pursuant to the Liquidating Trust Agreement, if any, shall be indemnified out of the liquidating trust assets against all liabilities and expenses, including amounts paid in satisfaction of judgments, in compromise or as fines and penalties, and all costs and expenses, including, but not limited to, reasonable counsel fees and disbursements paid or incurred in investigating or defending against any such claim, demand, action, suit or proceeding in connection with the defense or disposition of any action, suit or other proceeding by EQC LT or any other person, whether civil or criminal, in which the foregoing indemnified person may be involved or with which such indemnified person may be threatened while in office or thereafter, by reason of its or his or her being or having been an EQC LT trustee, employee or agent; provided, however, that such indemnified person shall not be entitled to such indemnification to the extent that it or he or she shall have been finally adjudicated to have engaged in misconduct committed in bad faith or with reckless indifference to the purposes of EQC LT or the interests of its beneficiaries.

~~The~~EQC’s Audit Committee ~~has~~had established policies and procedures to review and approve the engagement of the Company’s independent auditor to provide any audit or non-audit services to the Company, either pursuant to the Audit Committee’s Policy Regarding Pre-Approval of Audit and Non-Audit Services (the “Pre-Approval Policy”) or through a separate pre-approval by the Audit Committee, which policies and procedures ~~are~~were intended to control the services provided by our independent registered public accounting firm and to monitor their continuing independence.

Under these policies and procedures, no services ~~may~~were permitted to be undertaken by the independent registered public accounting firm unless the engagement iswas specifically approved by the Audit Committee or the services ~~are~~were included within a category that ~~has~~had been pre-approved in the Pre-Approval Policy. The maximum charge for services iswere to be established by the Pre-Approval Policy or by the Audit Committee when the specific engagement or the category of services iswas approved.

In our opinion, the consolidated financial statements present fairly, in all material respects, the ~~financial~~net ~~position~~assets in liquidation of ~~the~~EQC ~~Company~~LT as of September 30, 2025 and December 31, ~~2023~~2024, the ~~results~~changes ofin its ~~operations~~net ~~and~~assets ~~its~~in ~~cash~~liquidation ~~flows~~ for the ~~period~~year ~~from~~ended ~~January~~September 130, ~~2024~~2025 ~~to October 31, 2024~~ and for the ~~years~~period ~~ended~~from ~~December~~November 311, ~~2023~~2024 ~~and~~to ~~2022, its net assets in liquidation as of~~ December 31, 2024, and the ~~changes~~results inof its ~~net~~operations ~~assets~~and inits ~~liquidation~~cash flows for the period from ~~November~~January 1, 2024 to ~~December~~October 31, 2024, in conformity with U.S. generally accepted accounting principles applied on the basis of accounting described below.

AsAdoption ~~described in Note 3 to the financial statements, the shareholders~~ of ~~the~~Liquidation ~~Company~~Basis ~~approved a plan~~ of liquidation on November 12, 2024, and the Company commenced liquidation shortly thereafter. As a result, the Company has changed its basis of accounting for periods subsequent to October 31, 2024 from the going concern basis to a liquidation basis.Accounting

Basis for Opinion

These financial statements are the responsibility of ~~the~~EQC ~~Company~~LT’s management. Our responsibility is to express an opinion on ~~the~~EQC ~~Company~~LT’s financial statements based on our audits. We are a public accounting firm registered with the Public Company Accounting Oversight Board (United States) (PCAOB) and are required to be independent with respect to ~~the~~EQC ~~Company~~LT 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 and in accordance with auditing standards generally accepted in the United States of America. 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~~EQC ~~audits~~LT ~~included~~is ~~performing~~not ~~procedures~~required to ~~assess~~have, ~~the~~nor ~~risks~~were ofwe ~~material~~engaged ~~misstatement of the financial statements, whether due~~ to ~~error or fraud~~perform, ~~and~~an ~~performing~~audit ~~procedures~~of ~~that~~its ~~respond~~internal tocontrol ~~those~~over ~~risks~~financial reporting. ~~Such~~As ~~procedures~~part ~~included~~of ~~examining~~our audits, onwe aare ~~test~~required ~~basis,~~to ~~evidence~~obtain ~~regarding~~an ~~the~~understanding ~~amounts~~of ~~and~~internal ~~disclosures~~control inover ~~the~~ financial ~~statements.~~reporting ~~Our~~but ~~audits~~not ~~also~~for ~~included evaluating~~ the ~~accounting~~purpose ~~principles~~of ~~used~~expressing ~~and~~an ~~significant~~opinion ~~estimates~~on ~~made~~the byeffectiveness ~~management,~~of asEQC ~~well~~LT’s asinternal ~~evaluating~~control ~~the~~over ~~overall presentation of the~~ financial ~~statements~~reporting. Accordingly, Wewe ~~believe~~express ~~that~~no ~~our~~such ~~audits provide a reasonable basis for our~~ opinion.

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~~EQC’s 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.

Opinion on Internal Control Over Financial Reporting

We have audited Equity Commonwealth’s internal control over financial reporting as of December 31, 2024, 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, 2024, 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 sheet of Equity Commonwealth as of December 31, 2023, the related consolidated statements of operations, equity and cash flows for the period from January 1, 2024 to October 31, 2024 and for the years ended December 31, 2023 and 2022, the consolidated statement of net assets (liquidation basis) as of December 31, 2024, the related consolidated statement of changes in net assets (liquidation basis) for the period from November 1, 2024 to December 31, 2024, and the related notes and financial statement schedule listed at Item 15(a) and our report dated February 27, 2025 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.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

Note 1. Organization

Equity Commonwealth, or the Company, isor EQC, was a real estate investment trust, or REIT, formed in 1986 under the laws of the State of Maryland. ~~Our~~Prior to its dissolution on June 13, 2025, the Company’s business iswas primarily the ownership and operation of office properties in the United States. As of September 30, 2025, we did not own any properties.

The Company ~~operates~~operated in an umbrella partnership real estate investment trust, or UPREIT, and ~~conducts~~conducted substantially all of its activities through EQC Operating Trust, a Maryland real estate investment trust, or the Operating Trust. ~~The~~Prior to its dissolution on June 13, 2025, the Company beneficially owned, 99.86% of the outstanding shares of beneficial interest, designated as units, in the Operating Trust, or OP Units, ~~as of December 31, 2024,~~ and the Company iswas the sole trustee of the Operating Trust. As the sole trustee, the Company generally ~~has~~had 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.

AsOn April 1, 2025, the Company announced that, in connection with its Plan of ~~December 31~~Sale and Dissolution, or the Plan of Sale, approved by its shareholders on November 12, 2024, ~~our~~the ~~portfolio~~Board ~~consisted~~authorized the Company’s final cash liquidating distribution of ~~one~~$1.60 ~~property~~per ~~(one~~common ~~building)~~share to be paid on April 22, ~~with~~2025 0to shareholders of record as of April 11, 2025.7 ~~million~~On ~~square~~April ~~feet~~22, ~~and~~2025, wethe ~~had~~Company paid this distribution to such shareholders in the aggregate amount of $~~160~~172.5 4 million. This ofbrought ~~cash~~the ~~and~~aggregate cash ~~equivalents~~liquidating distributions to $20. ~~The~~60 ~~numbers~~per common share, inclusive of ~~buildings~~$19.00 ~~and~~per ~~square~~share ~~feet~~paid ~~are~~in ~~unaudited~~December 2024.

On April 11, 2025, in connection with the Plan of Sale and the Company’s final cash liquidating distribution, the Company filed a Form 25 (Notification of Removal from Listing) with the U.S. Securities and Exchange Commission, or the SEC, and the NYSE relating to the delisting of the common shares. The Company’s last day of trading on NYSE was April 21, 2025.

On June 13, 2025, or the Effective Date, as part of the Plan of Sale, the Company transferred its remaining assets and liabilities to EQC Liquidating Trust, or EQC LT, a newly-created Maryland common law trust, for the benefit of the common shareholders of the Company. In conjunction with the transfer, EQC LT distributed all of its units of beneficial interests to EQC’s common shareholders on a one-for-one basis, with each common shareholder receiving one unit in EQC LT, or the Units, for each EQC common share then held of record. All outstanding EQC common shares were then cancelled, and the Company was dissolved and terminated.

EQC LT was formed to wind up the affairs of EQC, the predecessor entity, liquidate EQC’s remaining assets, pay any liabilities, costs and expenses of EQC which were assumed or incurred by EQC LT, and distribute any net proceeds to the holders of the Units.

Under the terms of the Liquidating Trust Agreement, the taxable year of the Liquidating Trust ends on December 31 of each year, unless the Liquidating Trust is dissolved or liquidated prior to such date, in which case, the Liquidating Trust’s taxable year ends on the date of such liquidation or dissolution. Since the Liquidating Trust canceled all of its outstanding units and dissolved on September 30, 2025, the taxable year end is September 30, 2025. We have aligned the fiscal year with the taxable year. The financial statements reflect the accounts and activities of EQC Liquidating Trust and its consolidated subsidiary and, for periods prior to June 13, 2025, its predecessor entity.

Note 2. Plan of Sale

On October 2, 2024, the Company filed a definitive proxy statement, or the Definitive Proxy, with the ~~U.S. Securities and Exchange Commission, or~~ SEC, related to a Special Meeting of Shareholders, or the Special Shareholder Meeting, for the following purposes: (i) to consider and vote upon the Plan of Sale and Dissolution of the Company, or the Plan of Sale, including the wind-down and complete liquidation of the Company, and the dissolution and termination of the Company, including the establishment of a Liquidating Entity (as defined in the Definitive Proxy), and (ii) on an advisory, non-binding basis, to consider and vote upon compensation ~~that may become~~ payable by the Company to its named executive officers in connection with the Plan of Sale, or the Executive Compensation Proposal. The Plan of Sale, which the Company’s Board of Trustees determined was in the best interests of the Company and its shareholders, ~~authorizes~~authorized the Company to sell all of its remaining properties, wind-down the Company’s affairs and distribute the net proceeds to shareholders. At the special shareholder meeting held on November 12, 2024, the Company’s shareholders approved both proposals with: (i) 85.5% of outstanding shares, and 99% of votes cast, in favor of the Plan of Sale proposal (two-thirds of outstanding shares required for approval), and (ii) 86.7% of votes cast in favor of the Executive Compensation Proposal (majority of votes cast required for approval).

The Company expects any future liquidity to its shareholders will be provided in the form of liquidating distributions. The Company anticipates making all liquidating distributions to its shareholders prior to the liquidation and dissolution of the Company and the establishment of a Liquidating Entity to pay any remaining liabilities. The Company can provide no assurances as to the ultimate amount or timing of its liquidating distributions or the timing of the complete liquidation and dissolution of the Company; however, the Company anticipates paying its final liquidating distribution and dissolving within six months of completion of the sale of its final property, which occurred on February 25, 2025.F-8

The Plan of Sale authorizes the Company to sell its remaining properties without further shareholder approval, pay or establish a reserve fund for all actual and contingent liabilities, distribute net proceeds to shareholders, and wind-down the Company’s affairs, including the complete liquidation and dissolution of the Company. The Plan of Sale also authorizes the Board to establish or convert into a Liquidating Entity, which we anticipate, but cannot be certain, will occur after our final liquidating distribution is made.

Upon establishing or converting to the Liquidating Entity, our shareholders will receive non-transferable interests in the Liquidating Entity in proportion to the number of common shares owned by such shareholders. The purpose of the Liquidating Entity will be to pay any remaining liabilities and distribute any remaining proceeds to the holders of the interests in the Liquidating Entity.

The Company expects to comply with the requirements necessary to continue to qualify as a REIT through its liquidation and dissolution, or until such time as any remaining assets are transferred to a Liquidating Entity; provided, however, that the Board may elect to terminate the Company’s status as a REIT if it determines that such termination would be in the best interest of the shareholders.

On June 13, 2025, the Company transferred its remaining assets and liabilities to EQC Liquidating Trust. The Company believes it complied with the requirements necessary to qualify as a REIT through its liquidation and dissolution on June 13, 2025, at which time the remaining assets were transferred to EQC LT. In conjunction with the transfer, EQC LT distributed all of its units of beneficial interests to EQC’s common shareholders on a one-for-one basis, with each common shareholder receiving one unit in EQC LT, or the Units, for each EQC common share then held of record. As of September 30, 2025, after paying all of its remaining liabilities and disposing of all of its assets, the Liquidating Trust cancelled all its outstanding Units and dissolved.

Note 3. Summary of Significant Accounting Policies

The accounting policies and practices related to real estate properties discussed below are applicable to any real estate properties owned for the then-applicable period.

Principles of Consolidation and Basis of Presentation

The accompanying consolidated financial statements and notes thereto have been prepared in accordance with U.S. generally accepted accounting principles, or GAAP, as contained within the Financial Accounting Standards Board, or FASB,

Accounting Standards Codification, or ASC, including Subtopic 205-30, “Liquidation Basis of Accounting,” as indicated, and

the rules and regulations of the SEC.

Pursuant to the Company’s shareholders’ approval of the Plan of Sale on November 12, 2024, the Company adopted the liquidation basis of accounting as of and for the periods subsequent to November 1, 2024 (as the approval of the Plan of Sale by the Company’s shareholders became imminent in early November 2024 based on the results of the Company’s solicitation of proxies from its shareholders for their approval of the Plan of Sale). Accordingly, on November 1, 2024, assets were adjusted to their estimated net realizable value, or liquidation value, which represents the estimated amount of cash or other consideration that the Company expected to realize through the disposal of assets. The liquidation values of the Company’s real estate properties are presented on a net realizable value basis at December 31, 2024. Liabilities are carried at their contractual amounts due or estimated settlement amounts.

The Company accrues costs and revenues that it expects to incur and earn as it carries out its liquidation activities through the end of the projected liquidation period to the extent it has a reasonable basis for estimation. Estimated costs expected to be incurred through the end of the liquidation period ~~include~~included budgeted property expenses and corporate overhead, costs to dispose of its real estate property, costs associated with satisfying known and contingent liabilities and other costs associated with the winding down and dissolution of the Company. Revenues are based on in place leases at properties prior to their sale. These amounts are classified as a liability for estimated costs in excess of estimated receipts during liquidation on the consolidated ~~statement~~statements of net assets. Actual costs and income may differ from amounts reflected in the financial statements because of the inherent uncertainty in estimating future events. These differences may be material. See Note 2, “Plan of Sale” and Note 4, “Liabilities for Estimated Costs in Excess of Estimated Receipts During Liquidation” for further discussion.

Actual costs incurred but unpaid prior to the Company’s adoption of the liquidation basis of accounting on November 1, 2024, are included in accounts payable and accrued expenses and distributions payable at December 31, 2024 on the consolidated ~~statement~~statements of net assets. All our liabilities under either the going concern basis of accounting or the liquidation basis of accounting are derecognized when we pay the obligation or when we are legally released from being the primary obligor under the liability.

Net assets in liquidation at December 31, 2024 represents the remaining estimated liquidation value available to shareholders upon liquidation. Due to the uncertainty in the estimated cash flows from operations and the time required to complete the Plan of Sale, actual liquidation costs and sale proceeds may differ materially from the amounts estimated.

As a result of the change to the liquidation basis of accounting, the Company no longer presents a consolidated balance sheet, a consolidated statement of operations, a consolidated statement of equity or a consolidated statement of cash flows subsequent to October 31, 2024. These statements are only presented for prior year periods. 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, unless the context indicates otherwise. All intercompany transactions and balances have been eliminated. F-9

Dollar amounts presented may be approximate. Share amounts are presented in whole numbers, except where noted.

Use of Estimates

Preparation of these financial statements in conformity with GAAP requires us to make estimates and assumptions that may affect the amounts reported in these financial statements and related notes. The Company is required to estimate all costs and revenue it expects to incur and earn through the end of liquidation including the estimated amount of cash it expects to collect on disposal of its assets and the estimated costs to dispose of its assets. All of the estimates and evaluations are susceptible to change and actual results could differ from these estimates.

Real Estate Properties

Liquidation Basis of Accounting

As of November 1, 2024, the Company’s real estate was adjusted to its estimated net realizable value, or liquidation value, to reflect the change to the liquidation basis of accounting. The liquidation value represents the estimated amount of cash or other consideration that the Company expected to realize through the disposal of its assets. The Company estimated the liquidation value of its real estate based on a contractual purchase price for the property. The liquidation value of the Company’s real estate is presented on an undiscounted basis and real estate is no longer depreciated. Subsequent to November 1, 2024, all changes in the estimated liquidation value of the real estate isare reflected as a change to the Company’s net assets in liquidation. Costs to sell the property such as credits for capital costs, contractual lease obligations and rent abatements are included in Liabilities for estimated costs in excess of estimated receipts during liquidation as of December 31, 2024.

Going Concern Basis

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~~the 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 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 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.F-10

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.

Certain of our formerly owned real estate assets contained hazardous substances, including asbestos. We believe any asbestos in our former buildings is contained in accordance with applicable regulations. We do not believe that there are other environmental conditions or issues at any of our former properties that have had or will have a material adverse effect on us. As of September 30, 2025 and December 31, 2024, 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

Going Concern Basis

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.

estimated expenses and other liquidation costs and are classified in liabilities for estimated costs in excess of estimated receipts during liquidation on the consolidated statement of net assets.

Going Concern Basis

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 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

Going Concern Basis

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, 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 ten months ended October 31, 2024 ~~and years ended December 31, 2023 and 2022~~.

EQC LIQUIDATING TRUST

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (Continued)

Income Taxes

WePrior ~~are~~to EQC’s dissolution on June 13, 2025, we were a REIT under the Internal Revenue Code of 1986, as amended, and ~~are~~were generally not subject to federal and state income taxes provided we ~~distribute~~distributed our taxable income to our shareholders and ~~meet~~met other requirements for qualifying as a REIT. We are also subject to certain state and local taxes without regard to our REIT status. As a grantor trust, EQC LT is not an income tax payer. EQC LT passes its taxable income or loss to the holders of the Units.

Going Concern Basis

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.

Note 4. Liabilities for Estimated Costs in Excess of Estimated Receipts During Liquidation

The liquidation basis of accounting requires the Company to estimate net cash flows from operations and to accrue all costs associated with implementing and completing the Plan of Sale. As of December 31, 2024, the Company estimated that it ~~will~~would have costs in excess of estimated receipts during the liquidation process. These amounts can vary significantly due to, among other things, ~~estimates of tenant improvement costs and capital expenditures,~~ the timing and amounts associated with discharging known and contingent liabilities and the costs associated with the winding down of operations. These costs ~~are~~were estimated and ~~are~~were anticipated to be paid out over the liquidation period which iswas ~~estimated~~completed toon ~~be complete by~~ September 30, 2025~~, however, no assurances can be provided that this date will be met~~.

~~Upon transition to the liquidation basis of accounting on November 1, 2024, the Company accrued the following revenues and expenses expected to be incurred during liquidation (in thousands):~~F-13

Note 5. Net Assets In Liquidation

There were 107,335,177 common shares outstanding and 873,406 unvested restricted stock units at target, prior to any shares expected to be surrendered to satisfy statutory tax withholding obligations in connection with the vesting of such common shares, at December 31, 2024 (See Note 1110). The net assets in liquidation as of December 31, 2024 were $178.9 million. Net assets in liquidation include projections of costs and expenses to be incurred during the estimated period required to complete the Plan of Sale. There is inherent uncertainty with these estimates and projections,. ~~and~~Cumulative ~~they~~cash ~~could~~liquidating ~~change~~distributions ~~materially~~paid ~~based~~to ~~on,~~common ~~among~~shareholders ~~other~~are ~~things,~~$2.2 billion ~~changes in the underlying assumptions of the projected cash flows~~($20.60 ~~Cumulative~~per ~~liquidating distributions paid to~~ common ~~shareholders~~share) ~~will~~and include the initial $2.0 billion ($19.00 per common share) paid prior to December 31, 2024 ~~plus~~and ~~any~~the ~~future~~final ~~distribution~~$172.4 million of($1.60 ~~our~~per ~~net~~common ~~assets~~share) inpaid ~~liquidation~~on April 22, 2025.

The decrease from total equity under the going concern basis of accounting as of October 31, 2024 to net assets in liquidation under the liquidation basis of accounting as of November 1, 2024 is primarily due to the liability for estimated costs in excess of estimated receipts during liquidation (See Note 4), the increase in estimated net realizable value of real estate and the write-off of assets and liabilities.

(1)Liquidation distributions are first applied against shareholder tax basis, but not below zero. To the extent liquidation distributions exceed shareholder tax basis, such excess is taxable gain in the year of receipt. To the extent liquidation distributions are less than shareholder tax basis, any loss will be recognized in the year the final liquidation distribution is received.

Series D Preferred Shares:

On November 12, 2024, in connection with the Plan of Sale, the Company announced that its Board of Trustees authorized payment of the liquidation preference to the holders of shares of the Company’s 6.50% Series D Cumulative Convertible Preferred Shares of beneficial interest, par value $0.01 per share (the Series D Preferred Shares). A payment of $25.00 per Series D Preferred Share, plus accrued dividends of $0.08576 per Series D Preferred Share, for the period from November 15, 2024 through December 3, 2024 (the Payment Date), was paid on the Payment Date to shareholders as of the Payment Date. This payment of $123.3 million paid all amounts due and owing the holders of the Company’s Series D Preferred Shares in connection with the previously disclosed shareholder approval of the Plan of Sale and, in accordance with the terms thereof, the Series D Preferred Shares ~~have~~had no further right or claim to any of the remaining assets of the Company.

In conjunction with the payment of the liquidation preference, the Series D Preferred Shares were suspended from the NYSE before market open on the Payment Date. A Form 25 was filed with the SEC to effect the withdrawal of the listing of the Series D Preferred Shares from the NYSE.

With respect to our historical going concern financial statements, each of our 4,915,196 series D cumulative convertible preferred shares accrued dividends of $1.625, or 6.50% per annum of the liquidation amount, payable in equal quarterly payments. Our series D preferred shares were 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 October 31, 2024. 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. Prior to the liquidation preference payment, holders of 1,265 Series D preferred shares converted their Series D preferred shares to 1,037 common shares.

Note 98. Noncontrolling Interest

Noncontrolling interest represents the portion of the OP Units not beneficially owned by the Company. 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, 2024, the portion of the Operating Trust not beneficially owned by the Company is in the form of OP Units and LTIP Units (see Note 11 for a description of LTIP Units). LTIP Units may be subject to additional vesting requirements.

FOn June 13, 2025, as part of the Plan of Sale, the Company transferred its remaining assets and liabilities to EQC LT. In conjunction with the transfer, EQC LT distributed all of its units of beneficial interests to EQC’s common shareholders and OP Unitholders on a one-20for-one basis, with each common shareholder and OP Unitholder receiving one unit in EQC LT, or the Units, for each EQC common share or OP Unit then held of record. All outstanding EQC common shares and OP Units were then cancelled, and the Company and Operating Trust were dissolved and terminated.

The following table presents the changes in Equity Commonwealth’s issued and outstanding common shares and units from January 1, 2025 through June 13, 2025, prior to EQC’s dissolution:


	Common Shares	OP Units and LTIP Units(1)	Total

Outstanding at June 13, 2025	107,751,132	154,578	107,905,710
Noncontrolling ownership interest in the Operating Trust			0.14	%

(1) The 101,634 LTIP Units outstanding as of June 13, 2025 did not participate in any Company liquidating distributions. The noncontrolling ownership interest in the Operating Trust that participated in liquidating distributions as of June 13, 2025 is 0.05%.

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 99.85% and 99.84%, respectively, for the period ended June 13, 2025 and year ended December 31, 2024.

Equity Commonwealth 2015 Omnibus Incentive Plan (2015 Omnibus Plan)

On June 16, 2015, at our 2015 annual meeting of shareholders, our shareholders approved the 2015 Omnibus Plan. The 2015 Omnibus Plan replaced the Equity Commonwealth 2012 Equity Compensation Plan (as amended, the 2012 Plan). The Board of Trustees approved the 2015 Omnibus 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 Omnibus 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 Omnibus Plan to increase the number of common shares of beneficial interest authorized thereunder by 2,500,000, and, at our annual meeting of shareholders on June 13, 2023, our shareholders approved an amendment to the 2015 Omnibus Plan to increase the number of common shares of beneficial interest authorized thereunder by 1,650,000 (hereafter, as amended, the 2015 Omnibus Plan). The following description of certain terms of the 2015 Omnibus Plan is qualified in all respects by the terms of the 2015 Omnibus Plan.

Eligibility. Awards ~~may~~were available to be granted under the 2015 Omnibus Plan to employees, officers and non-employee ~~directors~~trustees of the Company, its subsidiaries or its affiliates, or consultants and advisors (who are natural persons) providing services to the Company, its subsidiaries or its affiliates, or any other person whose participation in the 2015 Omnibus Plan is determined by the Committee to be in the best interests of the Company.

Shares Available for Issuance. Subject to adjustment as provided in the 2015 Omnibus Plan, the maximum number of common shares of the Company that were available for issuance under the 2015 Omnibus Plan was 7,400,000 shares.

Awards. The following types of awards were available to be made under the 2015 Omnibus Plan, subject to limitations set forth in the 2015 Omnibus 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 conducts or may conduct its business;

· Other equity-based awards; and

· Cash awards.

Recipients of the Company’s restricted shares ~~have~~had the same voting rights as any other common shareholder. During the period of restriction, holders of unvested restricted shares ~~are~~were 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~~were service based awards and ~~vest~~vested over a service period determined by the Committee.

Recipients of the Company’s restricted stock units, or RSUs, ~~are~~were entitled to receive dividends with respect to the common shares underlying the RSUs if and when the RSUs ~~are~~were earned, at which time the recipient ~~will~~was 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~~did not vest, the dividends related to unvested RSUs ~~will~~were be forfeited. The RSUs ~~are~~were market-based awards with a service condition and recipients ~~may~~earned ~~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~~were be determined. The earned awards ~~vest~~vested in two tranches with 50% of the earned award vesting following the end of the performance period on the date the Committee determined 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 was determined using a Monte Carlo simulation model and was recognized ratably from the grant date to the vesting date of each tranche.

FLTIP Units were 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-22based LTIP Units had the same general characteristics as restricted shares and market-based LTIP Units had the same general characteristics as RSUs. Each LTIP Unit converted automatically into an OP Unit on a one-for-one basis when the LTIP Unit vested and its capital account equalized with the per-unit capital account of the OP Units. Holders of LTIP Units generally were entitled to receive the same per-unit distributions as the other outstanding OP Units in the Operating Trust, except that market-based LTIP Units did not participate in distributions until expiration of the applicable performance period, at which time any earned market-based LTIP Units generally became entitled to receive a catch-up distribution for the periods prior to such time.

Administration. The 2015 Omnibus Plan was administered by the Company’s Compensation Committee, which determined all terms and recipients of awards under the 2015 Omnibus Plan.

2025 Equity Award Activity

Our Board determined that a change in control occurred on February 25, 2025 as a result of the sale of 1225 Seventeenth Street Plaza, which it determined constituted a sale of substantially all of our assets. Accordingly, equity awards outstanding that remained unvested on February 25, 2025 vested on an accelerated basis.

During the period from January 1, 2025 through June 13, 2025, 873,406 RSUs vested, and, as a result, we issued 873,406 common shares, prior to certain employees surrendering their common shares to satisfy tax withholding obligations (see Note 7).

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 Omnibus Plan will be administered by the Committee, which will determine all terms and recipients of awards under the 2015 Omnibus Plan.

~~The unvested restricted shares, time based LTIP Units, and RSUs and Market~~F-Based LTIP Units, to the extent they become earned, are scheduled to vest between 2025 and 2028 or upon a change in control of the company if such change in control occurs before their scheduled vesting date. Our Board determined that a change in control occurred on February 25, 2025 as a result of the sale of 1225 Seventeenth Street Plaza, which it determined constituted a sale of substantially all of our assets. Accordingly, equity awards outstanding that remain unvested on February 25, 2025 will vest on an accelerated basis. Compensation expense for the restricted share and time-based LTIP Units through October 31, 2024 was recognized on a straight-line basis over the requisite service period (through their respective scheduled vesting date) for each separately vesting portion of the award. 20

In December 2024, as part of the Plan of Sale and to facilitate an efficient wind-down of the Company, the Company terminated its various Registration Statements on Form S-8, which were used to register the Company’s common shares reserved for issuance as equity awards pursuant to the 2015 Omnibus Plan.

Note 12. Fair Value of Assets and Liabilities

Properties Held for Sale (Going Concern Basis)

Fair value is defined as the exchange price that would be received for an asset or paid to transfer a liability (an exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. A three-level valuation hierarchy exists for disclosures of fair value measurements based upon the transparency of inputs to the valuation of an asset or liability as of the measurement date. A financial instrument's categorization within the valuation hierarchy is based upon the lowest level of input that is significant to the fair value measurement. The three levels are defined below:

•Level 1 - Quoted prices in active markets for identical assets or liabilities.

•Level 2 - Observable inputs other than Level 1 prices such as quoted prices for similar assets or liabilities, quoted prices in markets that are not active, or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the assets or liabilities.

•Level 3 - Unobservable inputs that are supported by little or no market activity and that are significant to the fair value of the assets or liabilities.

At September 30, 2024, we had classified 1250 H Street, NW, 206 East 9th Street and Bridgepoint Square as held for sale in accordance with ASC 360. As a result of our current estimates of market value less estimated costs to sell, it was necessary to record impairment charges for the ten months ended October 31, 2024 of $49.3 million which includes $16.3 million of impairment related to non-real estate assets. We determined these impairments based on contractual purchase prices for the properties, which are level 2 inputs according to the fair value hierarchy established in ASC 820. We reduced the aggregate carrying values of these properties from $136.9 million to their estimated fair value less estimated costs to sell of $87.6 million. These properties were sold in the fourth quarter of 2024 (See Note 6).

Our financial instruments include our cash and cash equivalents. At December 31, 2024 ~~and 2023~~, 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. As of December 31, 2024, three individual tenants were responsible for more than 10% of our future minimum lease payments, excluding tenant reimbursement revenue (see Note 6).

Note 13. Segment Information

Our primary business was the ownership and operation of office properties, and we have one reportable segment. One hundred percent of our revenues for the ten months ended October 31, 2024 were from office properties.

We define our segments on the basis in which internally reported financial information is regularly reviewed by the chief operating decision maker, or CODM, to analyze financial performance, make decisions, and allocate resources. Our CODM is ~~our~~the person who served as the Company’s Executive Vice President and Chief Operating Officer. Our CODM uses components of net income in the annual budget and forecasting process. The CODM considers budget-to-actual variances on a quarterly basis when making decisions about the allocation of operating and capital resources. Our significant segment expenses include operating expenses and general administrative expenses which are presented on our consolidated statements of operations.
