Arhaus, Inc.

Evaluation of Disclosure Controls and Procedures

Management, with the participation of our CEO and Chief Financial Officer (“CFO”), evaluated the effectiveness of the design and operation of our disclosure controls and procedures (as defined in Rules 13a-15(e) and 15d-15(e) of the Securities Exchange Act of 1934 (“Exchange Act”)) as of March 31, 2026. Based upon that evaluation as of March 31, 2026, our CEO and CFO have concluded that our disclosure controls and procedures were not effective at the reasonable assurance level because of the material weaknesses in our internal control over financial reporting described below.

Despite these material weaknesses, our CEO and CFO concluded the financial statements were prepared in accordance with U.S. GAAP.

Material Weaknesses in Internal Control Over Financial Reporting

A material weakness is a deficiency, or a combination of deficiencies, in internal control over financial reporting (“ICFR”), such that there is a reasonable possibility that a material misstatement of a company’s annual or interim financial statements will not be prevented or detected on a timely basis. We identified the following material weaknesses in our ICFR.

•We did not design and maintain an effective control environment due to a lack of an appropriate level of experience and training related to internal control over financial reporting. Additionally, the lack of experience and training resulted in an inability to consistently establish appropriate authorities and responsibilities in pursuit of our financial reporting objectives, as demonstrated by, amongst other things, insufficient segregation of duties across our significant business processes. This material weakness contributed to the following additional material weakness.

•We did not design and maintain sufficient accounting policies, procedures and controls, or maintain adequate documentary evidence of existing control activities over significant accounts and disclosures to achieve complete, accurate and timely financial accounting, reporting and disclosures, including adequate controls over the period-end financial reporting process and the preparation and review of journal entries, including assessing the reliability of reports and spreadsheets used in controls.

These material weaknesses resulted in a restatement of our previously issued annual consolidated financial statements as of and for the years ended December 31, 2020 and 2019 principally related to selling, general and administrative expenses and other long-term liabilities, and misclassifications in the balance sheets and statements of comprehensive income. These material weaknesses also resulted in immaterial adjustments recorded prior to the issuance of the consolidated financial statements as of and for the year ended December 31, 2021 principally related to property, furniture and equipment, net; selling, general and administrative expenses and misclassifications in the balance sheet and statement of cash flows.

In preparation of the December 31, 2023 consolidated financial statements and in preparation of the March 31, 2024 condensed consolidated financial statements, these material weaknesses resulted in restatements as of and for the interim period ended September 30, 2023 and revisions as of and for the annual periods ended December 31, 2023, 2022 and 2021, and as of and for the interim periods ended June 30, 2023, March 31, 2023, December 31, 2022, September 30, 2022, June 30, 2022 and March 31, 2022, principally related to prepaid and other current assets, property, furniture and equipment, net and operating lease liabilities, which resulted in misclassifications in the balance sheets and statements of cash flows and the timely recording of liabilities, operating right-of-use assets and operating lease liabilities. There were also immaterial misstatements. Additionally, each of the material weaknesses could result in misstatements to substantially all of our accounts or disclosures, that would result in a material misstatement to the annual or interim consolidated financial statements that would not be prevented or detected.

•Lastly, we did not design and maintain effective controls over information technology (“IT”) general controls for information systems that are relevant to the preparation of our financial statements. Specifically, we did not design and maintain: (i) program change management controls for financial systems to ensure that information technology program and data changes affecting financial applications and underlying accounting records are identified, tested, authorized and implemented appropriately; (ii) user access controls to ensure appropriate segregation of duties and that adequately restrict user and privileged access to financial applications, programs, and data to appropriate Company personnel; (iii) computer operations controls to ensure that critical batch jobs are monitored and data backups are authorized and monitored; and (iv) testing and approval controls for program development to ensure that new software development is aligned with business and IT requirements.

These IT deficiencies did not result in material adjustments to our consolidated financial statements, however, the deficiencies, when aggregated, could impact maintaining effective segregation of duties, as well as the effectiveness of IT-dependent controls (such as automated controls that address the risk of material misstatement to one or more assertions, along with the IT controls and underlying data that support the effectiveness of system-generated data and reports) that could result in misstatements potentially impacting all financial statement accounts and disclosures that would not be prevented or detected. Accordingly, management has determined these IT deficiencies in the aggregate constitute a material weakness.

Remediation Activities

As of March 31, 2026, the previously disclosed material weakness related to not designing and maintaining effective controls to address the identification of and accounting for certain non-routine or complex transactions, including the proper application of U.S. GAAP of such transactions was remediated through the following:

•Hired and retained personnel with the knowledge and experience to identify and account for non-routine orcomplex transactions, including the proper application of U.S. GAAP to such transactions.

•Enhanced company policies related to review of significant contracts prior to execution for critical accounting terms.

•Enhanced controls over non-routine or complex transactions to ensure a complete and accurate population of transactions to validate proper application of U.S. GAAP for such transactions.

With the oversight of senior management and our Audit Committee, we continue to assess, implement and redesign our ICFR. Although the material weaknesses existing as of March 31, 2026 cannot beconsidered remediated until the related controls have operated effectively for a sufficient period of time and have been tested, we have made meaningful progress and continue to execute our remediation plan, including:

•Established a cross functional taskforce of senior leaders with expertise in designing and implementing internal controls to oversee remediation activities. The taskforce is responsible for the oversight of our remediation plan including development of actions plans for individual control deficiencies.

•Established regular meetings between senior management and members of the Audit Committee to discuss and report on remediation progress and objectives. Additionally, progress updates are regularly provided to the Board of Directors.

•Outsourced our internal audit department to a third-party service firm and transitioned our former internal audit department to our business process improvement function, which is assisting with control design, implementation, and remediation execution.

•Evaluated and enhanced the accounting organization by assessing personnel competency and capacity, hired additional qualified technical accounting, financial reporting, and lease accounting experts (including senior level leaders), and strengthened training, oversight, and the internal review processes to ensure the team possesses the appropriate knowledge and experience to design, execute, and oversee ICFR related activities.

•Assessed and continue to evaluate the IT function to ensure that it is adequately staffed with personnel possessing the necessary ICFR related knowledge and competencies. Significant personnel additions have been made within our IT department and across the organization, including executive and senior level hires.

•Hired and continue to hire additional personnel to enhance the segregation of duties in the IT department, particularly between IT development and IT operations.

•A multi-year company-wide initiative has begun to modernize the Company’s IT infrastructure to be capable of streamlining many of our manual financial reporting processes, enhancing our information technology control environment and mitigating the underlying internal control gaps and limitations that cannot be remediated within current systems.

•Conducting and continuing to conduct trainings for control owners and performers on key ICFR topics including, but not limited to:

–user access review completion;

–review and conclusions around Systems and Organization Control I (“SOC1”) reports;

–software used in accounting;

–validation of the system generated data used in the execution of a control;

–account reconciliation formats and required support;

–journal entry review and support; and

–maintaining evidence of control support.

•Enhanced communications to employees regarding our internal control environment and related expectations. We continue to take steps to ensure personnel both existing and newly hired are adequately trained with the appropriate level of knowledge and understanding of ICFR and its importance.

•Updated our policies and procedures to establish and maintain effective segregation of duties for our accounting staff in relation to journal entries, reconciliationsand other applicable processes. To supplement existing procedures, management implemented an account reconciliation software tool which increased the reliability around the monthly financial statement close procedures through utilization of period-end closing task checklists and standardized reconciliation processes.

•Designed and implemented formal processes, policies and procedures to support our financial close process, including but not limited to:

–formalized procedures over the review of our financial statements;

–implemented period-end closing task checklists; and

–standardized reconciliation process.

•Management will continue to evaluate and refine its financial statement close process to enhance processes around the preparation and review of journal entries, including assessing the reliability of reports and spreadsheets used in controls. Enhanced the design of the control activities over the review of our consolidated balance sheet and statement of cash flows to help ensure that the classification of operating and investing activities is appropriately presented in the statement of cash flows.

•Designed and implemented policies and procedures, including but not limited to:

–lease accounting;

–revenue recognition;

–inventory;

–goodwill and other long-lived assets;

–fixed assets and software capitalization;

–merchandise warranties; and

–income taxes.

•Continued to enhance the design and operation of user access control activities and procedures to help ensure access to IT applications and data is adequately restricted to appropriate personnel, including the implementation of user and privileged access reviews, password policy enforcement and user provisioning and deprovisioning.

•Continued designing and implementing additional program change management policies and procedures, control activities, and tools to help ensure that changes affecting key financial systems related to IT applications and underlying accounting records are identified, authorized, tested, and implemented appropriately.

•Designed and implemented a formal systems development lifecycle methodology and related program development controls to help ensure that significant IT change events are appropriately tested and approved. These controls will need to operate for a period of time and be tested for operating effectiveness.

•Continued to enhance the design and operation of control activities and procedures within the computer operations domain to help ensure that key batch jobs and interfaces are monitored, processing failures are adequately resolved, and recovery capability is tested.

•Continued to enhance data backup procedures to help ensure that systems are adequately backed up and maintained and recovery of data from backups is tested.

•Continued identifying, evaluating and began testing key IT dependencies including key reports, automated application controls, interfaces and end user computer operations.

Although we have developed and will continue to evaluate our plan, we are in the process of implementing internal controls to remediate the material weaknesses and believe, based on our evaluation to date, that the material weaknesses will be remediated as soon as is practicable, we cannot project a specific timeline on when the plan will be fully implemented. The material weaknesses will not be remediated until the necessary internal controls have been designed, implemented, tested and determined to be operating effectively. In addition, we may need to take additional measures to address the material weaknesses or modify the planned remediation steps, and we cannot be certain that the measures we have taken, and expect to take, to improve our internal controls will be sufficient to address the issues identified, to ensure that our internal controls are effective or to ensure that the identified material weaknesses will not result in a material misstatement of our consolidated financial statements. Moreover, we cannot provide assurance that we will not identify additional material weaknesses in our ICFR in the future. Until we remediate the material weaknesses, our ability to record, process and report financial information accurately, and to prepare our consolidated financial statements within the time periods specified by the rules and forms of the SEC, could be adversely affected.
