2021 PROXY STATEMENT

DEAR FELLOW STOCKHOLDERS OF AT HOME GROUP INC.: I am pleased to invite you to the 2021 Annual Meeting of Stockholders (the “Annual Meeting”) of At Home Group Inc., on Wednesday, June 16, 2021, at 2:30 p.m. (Central Time), to be held by a virtual-only format at www.virtualshareholdermeeting.com/HOME2021. I began serving as independent Lead Director in September as part of our ongoing Board succession planning, following the great leadership provided by Larry Stone in establishing the foundation for this critical role. Larry is retiring as of the Annual Meeting, and I am honored to have been selected to succeed him. Strong Performance Despite Unprecedented Challenges in Fiscal Year 2021 Fiscal year 2021 was a transformational year for At Home, with unprecedented challenges met head-on by our management and team members, including mandated store closures in early fiscal year 2021, followed by record net sales in the last three quarters of the fiscal year. We believe our strong sales performance was driven by a number of operational initiatives as well as macroeconomic and consumer trends. Our dedicated management and team members rapidly accelerated our omnichannel capabilities to provide customers with additional options for purchasing our products, including Buy Online Pick-Up In Store, curbside pick-up and local delivery from a majority of store locations. Our rebounded sales performance allowed us to bring back many of our furloughed employees and institute merit increases. Ultimately, our fiscal year 2021 performance resulted in earned annual bonuses of 200% of target, based on achieving greater than maximum performance for both performance metrics (adjusted operating income and total sales growth), with no effective adjustments made to the bonus plan or performance goals developed in early fiscal year 2021. Significant Board Oversight of COVID-19 Pandemic Response The Board and its Committees were deeply engaged throughout fiscal year 2021 and provided significant oversight of key measures considered and taken in response to the COVID-19 pandemic. The Board monitored the risks related to our business, continuity and strategy. The Audit Committee oversaw the management of liquidity and cash flows, debt covenant compliance, key accounting and financial reporting considerations, legal and regulatory compliance, cybersecurity, and internal control considerations. The Compensation Committee reviewed our efforts to ensure the safety and well-being of our employees, as well as overseeing our furlough and layoff programs and key compensation matters. In particular, the Board met periodically to discuss developments related to the COVID-19 pandemic and At Home’s responses. In addition, an executive committee of our Board, together with other Board members able to attend, informally met with members of our management team weekly from late March to early June in fiscal year 2021 to discuss similar matters. Key matters addressed included our store closures, employee furloughs, temporary tiered salary reductions for corporate employees, deferral of annual merit increases and bonuses, substantial reductions in expenses, store occupancy costs, capital expenditures and overall costs (including the suspension of new store openings and remodeling projects), extending payment terms with our vendors, negotiating rent deferrals or rent abatements, and the expansion of our omnichannel capabilities. Ultimately, this group oversaw the reversal of some of the temporary measures taken in response to the pandemic, such as reopening stores in compliance within a myriad of complex state and local regulations, bringing back many furloughed employees, restoring salaries and instituting merit increases. Although many challenges and uncertainties from the COVID-19 pandemic remain, we look to build upon the strong success of fiscal year 2021 and the enhanced implementation of our At Home 2.0 strategy. Continuing Board Refreshment Our Board has evolved significantly since our initial public offering in 2016. We have appointed five new directors since 2018, and our Board now includes four female directors and one ethnically diverse director. We believe the continuing directors represent the appropriate mix of experience, skills, expertise, backgrounds and other attributes to ensure that the Board, as a whole, will continue to effectively perform its oversight function on behalf of stockholders in light of the Company’s ongoing operations and long-term strategy. In October of fiscal year 2021, Martin Eltrich, III resigned from the Board following the sale of the remaining shares held by funds affiliated with AEA Investors LP, our former private equity sponsor. In November, the Board appointed Kenneth Simril

as a Class III director. Mr. Simril is the current President and Chief Executive Officer of Fleischmann’s Ingredients and, as a former Chief Financial Officer of multiple companies, the Board has determined that he qualifies as an audit committee financial expert. Further, in March of fiscal year 2022, Larry Stone informed the Board of his intention to retire upon expiration of his current term and not stand for re-election at the Annual Meeting. On behalf of the Board, I want to sincerely thank Martin and Larry for their dedicated service and contributions. Ongoing Responsiveness to Significant Fiscal Year 2020 Stockholder Engagement Following our Say-on-Pay failure at the 2019 annual meeting of stockholders, Larry led a significant stockholder engagement effort regarding our executive compensation program in late fiscal year 2020. Such outreach led the Compensation Committee to expedite the shift of the Company’s executive compensation structure from a private-equity sponsor model to a mature public company model. Although planned progress was delayed in part in fiscal year 2021 due to the COVID-19 pandemic, the fundamental changes implemented in our fiscal year 2021 and fiscal year 2022 executive compensation program, described in the accompanying proxy statement, reflect our Board’s desire to learn from and work with long-term stockholders to achieve success for the Company and its stakeholders. Enhanced Focus on Human Capital Management and Sustainability The Board and the Compensation Committee are highly focused on oversight of human capital management. Issues related to human capital management and our culture are discussed at Board meetings and both the Board and committees devote time each year to discuss functional leadership across the Company and succession plans. Management is responsible for shaping our culture, including setting the right tone-at-the-top and ensuring our policies and processes reflect and reinforce our values. In fiscal year 2021, the Board was focused on policies and programs that support diversity and inclusion, including our twelve key areas of focus identified following focused listening sessions and a team member survey completed in the first half of fiscal year 2021, and the safety and well-being of our team members through our Safe Stores Policy and our Safe Home Office Policy and our various team member wellness programs. Our management team and Board, with oversight leadership from the Audit Committee, also are increasingly focused on social responsibility and sustainability. In fiscal year 2021, we committed to issuing our first Sustainability Report this spring, which we expect to release in May 2021, and will continue to monitor and assess our progress with respect to corporate social responsibility matters in fiscal year 2022 and beyond. On behalf of the Board, thank you for your continued investment in At Home. We appreciate the trust you place in us. Philip L. Francis Independent Lead Director May 4, 2021

TO THE STOCKHOLDERS OF AT HOME GROUP INC.: You are cordially invited to attend the 2021 Annual Meeting of Stockholders (the “Annual Meeting”) of At Home Group Inc., on Wednesday, June 16, 2021, at 2:30 p.m. (Central Time), to be held by a virtual-only format. Stockholders as of the record date may participate in a live webcast of the meeting at www.virtualshareholdermeeting.com/HOME2021. At the Annual Meeting, you will be asked to: 1 Elect three Class II directors to the Board of Directors to hold office until the 2024 annual meeting of stockholders. 2 Approve (on an advisory basis) the compensation of our named executive officers. 3 Ratify the appointment of Ernst & Young LLP as our independent registered public accounting firm for the fiscal year ending January 29, 2022. 4 Approve an amendment to our 2016 equity incentive plan to increase the shares of common stock available for issuance and to make other specified revisions. & Transact any other business that may properly come before the Annual Meeting or any adjournment or postponement thereof. In addition, our management and the Board will be available to respond to comments and questions of general interest to our stockholders. It is important that you vote whether or not you plan to attend the Annual Meeting. At Home is a leading home décor superstore, and we believe our large format stores dedicate more space per store to home décor than any other player in the industry. We are focused on providing the broadest assortment of everyday and seasonal products for any room, in any style, for any budget. We utilize our space advantage to out-assort our competition, offering over 50,000 SKUs throughout our stores. Our differentiated merchandising strategy allows us to identify on-trend products and then value engineer similar products to provide desirable aesthetics at attractive price points for our customers. Over 75% of our products are unbranded, private label or specifically designed for us. We have developed a highly efficient operating model that seeks to drive growth and profitability while minimizing operating risk. Our merchandising, sourcing and pricing strategies generate strong ticket growth across our product offering and increase store traffic and time in store. Through specialized in store merchandising and visual navigation elements, we enable a self-service model that minimizes in store staffing needs and allows us to deliver exceptional value to our customers. We believe with our quickly expanding omnichannel offering, broad and comprehensive assortment, enhanced focus on customer loyalty and compelling value proposition, we are a leading destination for home décor with the opportunity to continue taking market share in a highly fragmented and growing industry. In terms of the past year, fiscal year 2021 was transformational for At Home. In the face of a global pandemic and store closures, our teams acted nimbly to launch omnichannel solutions, reopen safely and serve customers during the unprecedented surge in demand that followed. Our record financial achievements would be remarkable in any year, but they hold special significance, given the difficult environment and the limited visibility we had for much of fiscal year 2021. These outstanding results also demonstrate that At Home 2.0, the updated long-term strategy we put in place at the end of fiscal year 2020, is propelling us forward. We thank you for your continued support and interest in At Home Group Inc. Sincerely, Lewis L. Bird III Chairman of the Board and Chief Executive Officer May 4, 2021

PROXY SUMMARY EXECUTIVE COMPENSATION HIGHLIGHTS Ongoing Responsiveness to Significant Fiscal Year 2020 Stockholder Engagement As a direct result of the targeted stockholder outreach, the Compensation Committee expedited the shift of the Company’s compensation structure from a private-equity sponsor model to a mature public company model. Although planned progress was delayed in part in fiscal year 2021 due to the COVID-19 pandemic, the fundamental changes implemented for our executive compensation program in fiscal years 2021 and 2022 reflect our Board’s desire to learn from and work with long-term stockholders to achieve success for the Company and its stakeholders. AT HOME GROUP INC. 2021 PROXY STATEMENT iii •In fiscal year 2022, the Compensation Committee approved a new long-term incentive program consisting of performance share units (“PSUs”) (50% of grant date value) and stock options (50% of grant date value) •Due to challenges related to setting objective performance goals in light of the COVID-19 pandemic, fiscal year 2021 annual equity awards to named executive officers were 100% stock options, which deliver value to the holder that is aligned with stockholder return •A special grant of PSUs was made in fiscal year 2021 to Mr. Bird with the same terms as the special grant of PSUs made to the other named executive officers in fiscal year 2020 “Add a reasonable portion of performance-based long-term equity and utilize fewer stock options” •Fiscal years 2021 and 2022 management bonus plans are solely based on the achievement of two new performance metrics, equally weighted: adjusted operating income and total sales growth “Preference for mix of metrics focused on top-line growth and profitability; many stockholders support total sales growth” •In fiscal year 2020, the Compensation Committee and Mr. Bird mutually agreed to cancel his fiscal year 2019 stock option award, which had an aggregate grant date fair value of $41.5 million and vested immediately on grant date, subject to certain transfer restrictions •Beginning in fiscal year 2021, the Compensation Committee has aligned the CEO compensation program (including equity awards) with other named executive officers and peer company/general market practices “Disfavor significant, one-time equity grants” We contacted holders of over 66% of our outstanding common stock, representing 22 Following our Say-on-Pay failure at the 2019of our top 30 stockholders annual meeting of stockholders, Mr. Stone, thenMr. Stone, together with certain members our independent Lead Director and Chair of theof management (excluding Mr. Bird, to Compensation Committee, led a significantencourage an open dialogue), stockholder engagement effort regarding ourmet with nine stockholders owning executive compensation program. In late fiscalover year 2020:46% of our outstanding common stock

PROXY SUMMARY Fiscal Year 2021—CEO Compensation Alignment with Named Executive Officers Mr. Bird’s target annual compensation in fiscal year 2021 substantially consisted of base salary, a target cash bonus, stock options and target PSUs. The target pay mix is set forth in the chart, excluding perquisites. Amounts may not add to 100% due to rounding. Target PSUs 8.8% Fixed 13.2% Base Salary 13.2% Mr. Bird’s actual compensation for fiscal year 2021 reflected the following key Target Bonus 17.3% determinations. Total Growth 8.7% Target Equity 69.4% No increase from fiscal year 2020, and an effective 50% voluntary reduction for the three-month period when home office employees were either furloughed or received reduced salaries (compared to a 30% voluntary reduction for other named executive officers) 60.6% All named executive officers received 200% of their bonus target due to greater than Named executive officers received 100% stock options for annual equity awards because options deliver value to the holder that is aligned with stockholder return but, unlike PSUs, did not require the Compensation Committee to set objective performance goals, which were very difficult to establish due to the COVID-19 pandemic and therefore may not have served the intended retention and incentive purposes Mr. Bird also received a special grant of PSUs that had the same terms as the special grant of PSUs made to the other named executive officers in fiscal year 2020, which further aligned the executive team to achieve two performance metrics linked to the Company’s business strategy and long-term profitability, adjusted net income growth and comparable store sales growth maximum performance for the management bonus plan metrics (adjusted operating income and total sales growth), with no effective adjustments made to performance goals approved in early fiscal year 2021 based on the Board-approved budget. In fiscal years 2020 and 2019, all named executive officers received 0% and 100.7% of their bonus targets, respectively AT HOME GROUP INC. 2021 PROXY STATEMENT iv 4 CEO PSUs 3 Equity 2 Bonus 1 Base Salary AT RISK 86.8% 2020 Annual Meeting Say-on-Pay Vote 97.5% Support The ongoing refreshment of the compensation program for named executive officers resulting from our significant stockholder engagement efforts resulted in high-level support at the 2020 annual meeting. •For fiscal years 2020 and 2021, special grants of PSUs are based on the achievement of adjusted net income and comparable store sales growth over eight fiscal quarters •In fiscal year 2022, annual grants of PSUs are based on adjusted net income and total sales growth, with three discrete annual performance goals to be established at or near the beginning of each fiscal year (with vesting no earlier than the third anniversary of the grant date) “Improve linkage between long-term equity and business strategy and long-term profitability”

We expect that the total Shares available for future Awards under the 2012 Option Plan and the 2016 Equity Plan, as amended by the Amendment, would be sufficient to cover expected equity grants for approximately four years based on current forecasts and estimates of future grants of equity awards, expected expirations, terminations and forfeitures and assuming maximum performance of future PSUs and that our share price remains at then-current levels or higher.

BOARD SUBSTANTIALLY COMPOSED OF INDEPENDENT DIRECTORS The Board recently undertook its annual review of director independence in accordance with the applicable rules of the NYSE. The independence rules include a series of objective tests, including that the director is not employed by us and has not engaged in various types of business dealings with us. In addition, the Board must make a subjective determination as to each independent director that no relationship exists which, in the opinion of the Board, would interfere with the exercise of independent judgment in carrying out the responsibilities of a director. In making these determinations, the Nominating and Corporate Governance Committee reviewed and discussed information provided by the directors and us regarding each director’s business and personal activities as they may relate to us and our management, and determined that no subjective independence concerns needed to be evaluated by the Board. The Board has affirmatively determined that the following nine of our ten current directors are independent directors under NYSE rules and our Corporate Governance Guidelines: Mr. Barbarick; Ms. Beck; Ms. Bennett; Mr. Butcher; Ms. Charles; Ms. Crevoiserat; Mr. Francis; Mr. Simril; and Mr. Stone. The Audit Committee, the Compensation Committee and the Nominating and Corporate Governance Committee are composed entirely of directors who are independent for Board service. In addition, after considering all of the relevant facts and circumstances, the Board has determined that each member of the Audit Committee and the Compensation Committee qualifies as independent in accordance with the additional independence rules established by the SEC and the NYSE for such committees.

BOARD MATTERS THE BOARD OF DIRECTORS—OTHER MATTERS The Board has general oversight responsibility for our affairs and, in exercising its fiduciary duties, the Board represents and acts on behalf of the stockholders. Our management is responsible for our day-to-day management, and the Board stays regularly informed about our business and provides oversight of and guidance to management through periodic meetings and other informal communications. Board Leadership—Combined Chairman and CEO Partnering with Empowered Independent Lead Director The Board is led by Mr. Bird, the Company’s Chairman and Chief Executive Officer. The Board believes the combined Chairman and Chief Executive Officer structure facilitates a unified strategic vision to set the overall tone and direction of the Company as well as clear leadership through consistency of communication. Concurrent with the loss of controlled company status in July 2018, the Board created the role of an independent Lead Director and appointed Mr. Stone to the position. Mr. Francis replaced Mr. Stone as Lead Director in September of fiscal year 2021. The Corporate Governance Guidelines provide that our independent directors will elect an independent Lead Director whenever the Chairman is not an independent director, with a term of at least one year. The Board believes that an effective independent Lead Director, such as Mr. Francis, who has significant and clearly delineated responsibilities as set forth in our Corporate Governance Guidelines, ensures strong, independent oversight of management and promotes effective governance and Board efficiency. In addition, independent directors are the sole members of the Audit, Nominating and Corporate Governance and Compensation Committees, which collectively oversee critical matters of the Company such as the integrity of the Company’s financial statements, enterprise risk management, the compensation of executive management, human capital management, sustainability, the appointment, nomination and evaluation of directors and the development and implementation of the Company’s corporate governance policies and structures. AT HOME GROUP INC. 2021 PROXY STATEMENT 12 Key Responsibilities of Independent Lead Director PHILIP L. FRANCIS Our independent Lead Director is empowered to: • Preside over all meetings and executive sessions of the independent or non-management directors. • Act as the liaison between the independent or non-management directors and the Chairman, as appropriate. • Call meetings of the independent or non-management directors when necessary or appropriate. • Assist in scheduling Board meetings, collaborate with the Chairman on Board meeting agendas and approve such agendas. • Collaborate with the Chairman in determining the need for special meetings of the Board. • Request the inclusion of materials for Board meetings and approve all material information sent to the Board. • Communicate to the Chief Executive Officer, together with the Chair of the Compensation Committee, the results of the Board’s evaluation of Chief Executive Officer performance. • Provide leadership and serve as temporary Chairman or Chief Executive Officer in the event of the inability of the Chairman or Chief Executive Officer to fulfill his/her role. • Be available for consultation and direct communication if requested by significant stockholders. • Recommend the retention of consultants and advisors who directly report to the Board, as appropriate.

BOARD MATTERS Enterprise Risk Management Process Effective risk management is part of our culture and critical to our success. The Audit Committee oversees the Company’s approach to enterprise risk management, which is designed to support the achievement of strategic objectives, improve organizational performance and enhance long-term stockholder value. At least annually, the Board and Audit Committee reviews and discusses a detailed report from senior management regarding its Company-wide enterprise risk management process, which is based on COSO’s 2004 Enterprise Risk Management—Integrated Framework and risk assessment guidance (the “ERM Process”). The ERM Process is designed to identify, assess, prioritize and respond to material risks or potential significant events that may affect the Company, and to assist in monitoring and reporting on identified risks. Pursuant to the ERM Process, risks are identified through, among other things, frequent meetings among senior management and executive leadership, quarterly disclosure committee meetings, the annual financial statement risk assessment and fraud risk assessment as part of the Company’s internal control assessment, and detailed interviews with executive management. Risks are prioritized based on quantitative and qualitative factors that consider the likelihood and impact of the risk, including financial brand/reputational, legal/regulatory and operational impacts. Management will align on critical risks and identify risk owners among the executive leadership, and identified risks are monitored and responded to with specific activities or monitoring or mitigation plans. We believe we have effective policies and processes that support a strong internal control environment to promote the early identification and continued mitigation of risks. Overall results are reported to and discussed with the Audit Committee at least annually on a formal basis and periodically as it relates to specific risks. The ERM Process is designed to promote effective preparation, collaboration and mitigation planning for potential risk incidents and related impacts. If a risk develops into an incident, the ERM Process is designed to ensure the right team of the Board and its committees, executive leadership and senior management and third-party advisors engage and collaborate on an effective response or mitigation plan on a timely basis. COVID-19 Pandemic Response and Omnichannel Strategy Our Board and its Committees were deeply engaged throughout fiscal year 2021 and provided significant oversight of key measures considered and taken in response to the COVID-19 pandemic. Our Board monitored the risks related to our business, continuity and planning, including our accelerated transition to omnichannel capabilities and the implementation of our At Home 2.0 strategy and the suspension of all new store openings and remodeling projects with the exception of seven stores that were at or near completion. Our Audit Committee oversaw the management of liquidity and cash flows, debt covenant compliance, key accounting and financial reporting considerations, legal and regulatory compliance and cybersecurity and other internal control considerations. Our Compensation Committee considered changes to our compensation programs, including our temporary base salary reductions, and reviewed our efforts to ensure the safety and well-being of our employees, including when we began to gradually reopen stores in late April and allowed our home office team members the flexibility to work from home or utilize our home office, as guided by our Safe Stores Policy, our Safe Home Office Policy and local regulations. Cybersecurity, Data Privacy and Data Security The Board recognizes the importance of maintaining the trust and confidence of our customers, especially as we further develop our omnichannel capabilities. Our Audit Committee has led oversight efforts related to cybersecurity, data privacy and data security matters, including receiving periodic reports from management. Beginning in fiscal year 2021, management reports on these matters at each regularly scheduled committee meeting, and we enhanced our information security capabilities, in particular to address risks related to working from home. Focus on Management Succession Planning The Corporate Governance Guidelines further provide that the Board oversee and approve succession planning relating to the Chief Executive Officer, and other executive officers as developed by management, at least annually. The Board has AT HOME GROUP INC. 2021 PROXY STATEMENT 14

BOARD MATTERS delegated oversight of succession planning to the Nominating and Corporate Governance Committee. The succession planning process for executive officers is designed to assist the Board in understanding the Company’s readiness and the related transition risks for a crisis as well as a planned or accelerated transition, and to oversee the development of a strong leadership bench and provide training opportunities for key employees. The Chief Executive Officer periodically provides the Board with an assessment of key executive officers for potential succession and discusses potential sources of external candidates. In fiscal year 2021, the Nominating and Corporate Governance Committee engaged a leading national advisory firm to assist its development of a long-term CEO succession planning process in partnership with Mr. Bird and the Company’s human resources leadership. The key objectives are to: • Increase stockholder value through strategic planning. • Establish key criteria for a successor. • Ensure long-term talent development among internal candidates. • Evaluate the internal candidates’ performance and potential over a long time period. • Link succession planning to the Company’s business and strategy. • Nurture a succession culture. • Benchmark sources of talent and other external data. The Nominating and Corporate Governance Committee continues to work with its advisory firm to manage this evolving process and establish milestones, with formal review and discussion on a regular basis at committee meetings as well as periodically among the Board. Board and Committee Meetings The Board and its committees meet throughout the year at regularly scheduled meetings, and also hold special meetings and act by written consent as appropriate. The non-management and independent directors hold regularly scheduled and at least quarterly executive sessions to meet without management present, which are led by our independent Lead Director, Mr. Francis. Our fully independent committees also regularly meet in executive sessions without management present. The Nominating and Corporate Governance Committee periodically discusses the structure of Board and committee meetings. This oversight role includes reviewing annual Board and committee calendars, the number of meetings held annually, supplemental informational updates provided by management and the Chairman of the Board, meeting efficiency and time allocated to critical oversight matters, the sufficiency of meeting materials and the self-evaluation process. Directors are expected to use their best efforts to attend all Board meetings, all meetings of committees of which they are a member and the annual meeting of stockholders. The Board met 15 times during fiscal year 2021, which included certain meetings to discuss developments related to the COVID-19 pandemic and At Home’s responses. In addition, an executive committee of our Board, together with other Board members able to attend, informally met with members of our management team weekly from late March to early June in fiscal year 2021 to discuss similar matters. Board and Committee Meeting Attendance Seven of the ten directors then in office attended our 2020 annual meeting of stockholders. Ms. Beck, Ms. Charles and Mr. Eltrich did not attend the 2020 annual meeting. AT HOME GROUP INC. 2021 PROXY STATEMENT 15 100% Attendance In fiscal year 2021, our incumbent directors attended 100% of meetings of the Board and our three standing committees.

BOARD MATTERS COMMITTEES OF THE BOARD The Board has established three standing committees to help carry out its duties.

Each committee may form, and delegate power and authority to, subcommittees of one or more of its members for any purpose that such committee deems appropriate. The Compensation Committee may also delegate limited authority and responsibilities to officers of the Company.

BOARD MATTERS For information concerning policies and procedures relating to the consideration and determination of named executive officer compensation, see “Compensation Discussion and Analysis.” Regulation Utilization of Compensation Consultant The Compensation Committee has the authority to engage an external independent compensation consultant to assist in the evaluation of executive compensation. The Compensation Committee re-engaged Pearl Meyer & Partners (“Pearl Meyer”) as its independent compensation consultant for fiscal year 2021 and approved the terms of the engagement, including the scope of work and fees. Representatives of Pearl Meyer are invited to attend certain Compensation Committee meetings. In fiscal year 2021 at the direction of the Compensation Committee, Pearl Meyer analyzed and made recommendations regarding the composition of our compensation peer group, provided an analysis of the compensation programs of our peer group, conducted compensation benchmarking against our peer group and general survey data and, based on this information, provided advice regarding the compensation programs for our senior management (including potential new hires) and independent directors, including recommendations regarding the form of equity awards for fiscal year 2021. Pearl Meyer reports to the Compensation Committee Chair and has direct access to Compensation Committee members, and periodically interfaces with members of the Compensation Committee. Pearl Meyer does not provide any other services to the Company. The Compensation Committee has assessed the independence of Pearl Meyer pursuant to applicable SEC and NYSE rules, and concluded that Pearl Meyer’s work for the Compensation Committee did not raise any conflict of interest for fiscal year 2021. Compensation Risk Analysis With the assistance of Pearl Meyer and management, our Compensation Committee reviewed our employee compensation policies, plans and practices to determine if they create incentives or otherwise encourage behavior that is reasonably likely to have a material adverse effect on us. Based on this review, our Compensation Committee concluded that there are no unmitigated risks created by our compensation policies, plans and practices that create incentives or encourage behavior that is reasonably likely to have a material adverse effect on the Company. Nominating and Corporate Governance Committee The principal responsibilities of the Nominating and Corporate Governance Committee are to: • • Evaluate the Board composition and structure.

BOARD MATTERS CORPORATE GOVERNANCE Our Board recognizes the critical importance of sound governance in representing the long-term interests of our stockholders.

Corporate Governance Guidelines We believe that good corporate governance helps to ensure that the Company is managed for the long-term benefits of our stockholders. We regularly review and consider our corporate governance policies and practices, the SEC’s corporate governance rules and regulations and the corporate governance listing standards of the NYSE. We have adopted Corporate Governance Guidelines that provide a framework for the governance of the Company as a whole and describe the principles and practices that the Board follows in carrying out its responsibilities. The Corporate Governance Guidelines address, among other things, the composition, structure and policies of the Board and its committees, the responsibilities and authority of our Chairman and independent Lead Director, director qualification standards, expectations and responsibilities of directors, management succession planning, the evaluation of Board and committee performance, principles of Board compensation and communications between stockholders and non-management directors. The Corporate Governance Guidelines are reviewed by the Nominating and Corporate Governance Committee from time to time to ensure that they effectively promote the best interests of both the Company and the Company’s stockholders and that they comply with all applicable laws, regulations and NYSE requirements. The Corporate Governance Guidelines are available on our website at investor.athome.com.

BOARD MATTERS following certification of the stockholder vote.

The Board will act on the Committee’s recommendation within 90 days following certification of the stockholder vote and promptly disclose its decision and rationale for accepting or rejecting the resignation in a public announcement. No Director Overboarding In fiscal year 2021, our Nominating and Corporate Governance Committee reviewed its policies regarding overboarding, including with reference to guidelines from large institutional investors, and reduced the number of public company boards on which a director may serve from five to four boards. Following such amendment, our Corporate Governance Guidelines provide that directors are expected not to serve on more than four public company boards, a director who is a chief executive officer of a public company is expected not to serve on the board of directors of more than two public companies, and members of the Audit Committee are expected not to serve on more than three public company audit committees (in each case, including the Company’s Board or committee). No exceptions to this policy were approved in fiscal year 2021 or currently are in effect. Annual Board and Committee Performance Evaluations With oversight from the Nominating and Corporate Governance Committee, the Board and each committee conducts a self-evaluation at least annually to determine whether the Board and such committees are functioning effectively and in accordance with their charters. These reviews focus on the Board and its committees as a whole and not on individual directors, unless circumstances otherwise warrant. The Nominating and Corporate Governance Committee determines the process for the annual Board and committee self-evaluations Each Board member participates in the self-evaluation process by responding to questions regarding the structure, composition, responsibilities, eﬀectiveness of meeting time and materials, management participation and responsiveness, and overall eﬀectiveness of the Board and any committees on which he or she serves General Counsel reviews and summarizes feedback in consultation with the chair of the Nominating and Corporate Governance Committee. Detailed discussions of results and opportunities for improvement are held with the full Board and each committee, typically in December The Board and committee chairs, together with management, utilize feedback received to identify priority action items, shape Board and committee composition and meeting agendas, and improve related processes, structure and substantive discussions Code of Business Principles We have adopted a Code of Business Principles applicable to all of our directors, officers and other employees, including our chief executive officer and chief financial officer. The Code of Business Principles is available on our website at investor.athome.com. It reflects our strong commitment to ethics and integrity, and provides guidance on making decisions that align with our core values. In the event that we amend or waive certain provisions of the Code of Business Principles applicable to our principal executive officer, principal financial officer, principal accounting officer or controller (or persons performing similar functions) that require disclosure under applicable SEC rules, we will disclose the same on our website.

BOARD MATTERS Director Training Director Orientation All new directors participate in our director orientation program during the first year on our Board. New directors receive an extensive suite of onboarding materials covering director responsibilities, corporate governance practices and policies, Board and committee processes, responsibilities and recent meeting materials, and a detailed overview of our business. Directors also participate in a series of meetings over time with management representatives from all functional business areas to review and discuss information about key matters. Our onboarding approach over the first year of Board service, together with participation in regular Board, committee meetings and informational meetings and gatherings, provide new directors with a strong foundation to understand our business, strategy, and culture, connect directors with management leadership and future successors, and accelerate their effectiveness to engage fully in Board deliberations. Directors have access to additional orientation opportunities upon acceptance of new or additional responsibilities on the Board and committees. Director Continuing Education Our Board believes that director continuing education is vital to the ability of directors to fulfill their responsibilities and supports increasing the effectiveness of the Board and committees. We enroll directors in the National Association of Corporate Directors, a leading authority on boardroom insights. Directors also may enroll in continuing education programs at our expense on corporate governance and other critical issues associated with a director’s service on a public company board or our industry. Our Board also hears regularly from management across functional areas of the business, including finance, human resources, merchandising, facilities, supply chain, product development, marketing and real estate development. In addition, the Board participates in store and home office visits, which were temporarily paused in fiscal year 2021 due to the COVID-19 pandemic. Ongoing Stockholder Engagement Throughout Fiscal Year It is a priority of the Company and the Board to maintain an active dialogue with our stockholders. Each year, the Company interacts with a broad base of stockholders through various engagement activities, including at various industry conferences, non-deal roadshows and one-on-one meetings and calls. The Company regularly engages with the Company’s stockholders to discuss fundamental matters, including business performance, strategy and financial results. We believe these interactions provide us with useful feedback and allow us to better understand our stockholders’ perspectives and priorities. Management reports to the Board on stockholder engagement on at least a quarterly basis, and the Board (or applicable committee) discusses such reports on a periodic basis. In late fiscal year 2020, Mr. Stone, then our independent Lead Director and Chair of the Compensation Committee, together with certain members of management, undertook a significant engagement effort to solicit feedback from stockholders on our executive compensation program. See “Proxy Summary―Executive Compensation Highlights” for detailed information on the Compensation Committee and Board’s ongoing responsiveness to our fiscal year 2020 stockholder engagement efforts.

BOARD MATTERS Employee Engagement We engage our workforce on a regular basis to build teamwork and to motivate them to be high performers. Our employee engagement begins from the very first day of work through our onboarding process that includes a welcome session with our CEO Mr. Bird to discuss our Company’s history, culture and strategy. We otherwise communicate with our employees in a variety of ways, including interactive quarterly town hall meetings led by Mr. Bird and senior executives, listening tours and lunches with Mr. Bird and workplace celebrations. Our team members are recognized for individual and team achievements and anniversaries. We also provide engagement training to company leadership to support these efforts. In addition, at the beginning of each shift, our store leaders huddle with their team members to provide direction and receive feedback on important issues of the day. We assess employee engagement through a variety of channels, including third-party led employee surveys. Employee Benefits, Health and Safety In response to the pandemic, we introduced new tools for communication and increased the regularity of widespread employee communication. We transitioned the frequency of our town hall meetings to be monthly rather than quarterly; we hosted executive listening sessions; we relaunched our monthly CEO small group sessions; and we introduced executive-sponsored employee engagement groups. Our executive leadership team and our internal communication team work together to share ongoing communications with our employees that address issues of interest and importance, with the most notable issues in fiscal year 2021 revolving around the pandemic. The importance we put on communication reinforces employee engagement, reminds our people of available resources, and promotes our At Home values and culture. We want our employees to thrive within and outside of their working environment. We provide a market competitive total rewards and benefits package to address the current needs of our employees, including their comprehensive health, financial wellness and quality of life coverage, as well as childcare support. We also host events and design resources aimed at protecting and supporting the physical, mental and financial health and well-being of our employees, including our annual corporate Wellness Week as well as safety training programs to prevent workplace accidents and injuries. We are proud to have created the At Home Foundation to provide financial assistance to eligible employees facing unforeseen hardship, including as a result of COVID-19. The At Home Foundation relies primarily on donations from employees in order to fund grants. We prioritize the safety and well-being of our employees, customers and communities. In response to the pandemic, we introduced numerous operational changes and protocols aimed at ensuring the health and safety of every individual in our stores. We are somewhat unique in that our large format stores offer space and wide aisles for social distancing. In addition to our store protocols, our corporate employees who are able to work remotely have been given the flexibility to continue doing so. And our Safe Home Office Policy ensures our corporate home office is safe, clean and available for employees who need or choose to use it. Diversity and Inclusion Our commitment to diversity begins at the top, with a diverse Board and executive leadership team. As of January 30, 2021, our corporate leadership team consists of 13 out of 29 or 45% female officers. The Board is focused on leadership accountability, team member awareness and policies and programs that support diversity and inclusion. The Board is committed to ensuring we consider diverse candidate lists for hiring and promotion for management positions. At Home strives to build a diverse, inclusive and respectful workplace for all employees. Our corporate culture, priorities and policies reflect our commitment to equality and contribute to driving strong performance. Our field teams intentionally tend to reflect the diversity of our customers and the communities where we operate. We have taken measures to ensure that our processes and policies around hiring, development, culture and tone at the top all support our efforts to be an employer of choice. We support and implement equal opportunity and gender pay equity, and we are mindful of unconscious bias that can impact our culture. Commitment to the Communities We Serve Our mission to enable everyone to affordably make their house a home has led us to focus our primary community service efforts to fundraise and donate our time to Habitat for Humanity (“Habitat”). Team members participate in Habitat build projects and raise funds, both directly and indirectly through the sale of products with proceeds then directed for donation.

BOARD MATTERS SUSTAINABILITY Consistent with our values, the Board and management prioritize long-term value creation, sustainability and corporate social responsibility. In fiscal year 2020, the Board delegated responsibility to the Audit Committee for the oversight of social responsibility and sustainability reporting and related matters important to our stakeholders, including evaluating how our business and operations impact the environment and our communities in the short-and long-term, and vice versa. With an enhanced focus by external stakeholders on environmental and social sustainability, we committed to issuing our first Sustainability Report this spring, which we expect to release in May, and we plan to continue to monitor and assess our progress with respect to corporate social responsibility matters in fiscal year 2022 and beyond. We expect our first report to include metrics aligned with the Sustainability Accounting Standards Board (SASB) standards for Multiline and Specialty Retailers & Distributors and to demonstrate where our efforts align with the United Nations’ Sustainable Development Goals.

BOARD MATTERS DIRECTOR COMPENSATION The Company’s directors receive a mix of cash and equity-based compensation. The compensation mix is intended to encourage directors to continue Board service, further align the interests of the Board and stockholders and attract new independent directors with outstanding qualifications. Fiscal Year 2021 Non-Employee Director Compensation Program The Compensation Committee revised the non-employee director compensation program for fiscal year 2020. The Compensation Committee utilized benchmarking against the same peer group used for named executive officer compensation, general industry survey data and related information from Pearl Meyer. Based on the Compensation Committee’s recommendation after its review of updated benchmarking and survey data and additional information from Pearl Meyer, the Board determined that no changes be made to the Company’s non-employee director compensation program for fiscal year 2021. The following table sets forth the compensation program for directors in effect during fiscal year 2021. Annual cash retainer: • Board 85,000 Additional annual cash retainers: • Lead Director 50,000 • Audit Committee Chair 25,000 • Compensation Committee Chair 20,000 • Nominating and Corporate Governance Committee Chair 15,000 Annual grant of restricted stock units (grant date fair value) 130,000 Cash Retainers—Impacted by COVID-19 Cash compensation is generally paid quarterly in advance of the regularly scheduled meetings. However, in fiscal year 2021, the independent directors elected to defer the payment of the Board, Lead Director and committee cash retainers for the first quarter due to the impact of the COVID-19 pandemic. In the second quarter, the Compensation Committee determined to pay the remaining quarterly cash retainers as scheduled, and to pay the first quarter cash retainers in equal installments with the payments for the third and fourth quarters. Annual Equity Award—Temporarily Reduced due to Limited Shares Available under 2016 Equity Plan Annual grants of restricted stock units (“RSUs”) to non-employee directors are made under the Amended and Restated At Home Group Inc. Equity Incentive Plan (the “2016 Equity Plan”) generally during the first quarter of each fiscal year. Any newly appointed or elected non-employee director will be granted a pro rata portion of such RSUs as of the effective date of initial appointment. The RSUs vest in full on the first anniversary of the grant date (or earlier in the event of termination of the director by the Company without cause upon or within one year following a change in control), subject to the director’s continued service to the Company through such vesting date. The RSUs will be settled in shares of the Company’s common stock within thirty days following the vesting date. The Compensation Committee sought to limit the size of fiscal year 2021 awards to ensure that there would be sufficient shares available under the 2016 Equity Plan to grant annual awards to executive officers, directors and employees for both fiscal years 2021 and 2022. Accordingly, the Compensation Committee reduced the number of shares to be awarded to non-employee directors by approximating the average share reduction to executive officers relative to their benchmarked levels (discussed under “Compensation Discussion and Analysis—Fiscal Year 2021 Compensation Program and Determinations—Annual Equity Award Program”). Accordingly, the Compensation Committee approved a grant of 16,300 AT HOME GROUP INC. 2021 PROXY STATEMENT 25 Fiscal Year 2021 ($)

BOARD MATTERS RSUs, resulting in the fiscal year 2021 grant to non-employee directors having a slightly lower grant date fair value than the $130,000 targeted value under our non-employee director compensation program. Other The Company reimburses expenses associated with attendance at Board meetings for all directors. The Company does not provide any perquisites to its independent directors. Director Equity Ownership Guidelines Our director equity ownership guidelines provide that our non-employee directors are expected to achieve and maintain ownership of equity with a total value equal to three times such director’s annual cash retainer for Board service (excluding any additional cash or equity retainer fees). Non-employee directors are expected to initially satisfy such guidelines within a five-year initial compliance period. As of the Record Date, all non-employee directors in service were either in compliance with the guidelines or within the compliance period and making appropriate progress. Fiscal Year 2021 Director Compensation Table The table below sets forth the compensation of each director in fiscal year 2021, excluding Mr. Bird whose compensation is disclosed in the Summary Compensation Table for fiscal years 2021, 2020 and 2019. (1) Represents the aggregate grant date fair value of the RSUs, equal to the closing price of the Company’s common stock on the grant date multiplied by the number of RSUs, in accordance with Financial Accounting Standards Board Accounting Standards Codification Topic 718 (“ASC 718”). The closing price per share of our common stock on June 22, 2020 (the grant date for all directors, other than Mr. Simril) was $7.58, and on November 20, 2020 (the grant date for Mr. Simril) was $16.74. The Company does not pay fractional RSUs. As of January 30, 2021, non-employee directors held the following stock options and RSUs: Mr. Barbarick, 16,300 RSUs; Ms. Beck, 16,300 RSUs and options to purchase 56,517 shares of common stock; Ms. Bennett, 16,300 RSUs; Mr. Butcher, 16,300 RSUs; Ms. Charles, 16,300 RSUs and options to purchase 3,488 shares of common stock; Ms. Crevoiserat, 16,300 RSUs; Mr. Francis, 16,300 RSUs and options to purchase 56,517 shares of common stock; Mr. Simril, 1,942 RSUs; and Mr. Stone, 16,300 RSUs and options to purchase 56,517 shares of common stock. Messrs. Eltrich and Questrom did not hold any stock options or RSUs as of such date. Mr. Eltrich previously was nominated for election to the Board by AEA and did not receive any individual compensation for his service as a director. Mr. Eltrich resigned from the Board in October of fiscal year 2021. Mr. Questrom resigned from the Board immediately prior to the 2020 annual meeting. Mr. Simril was appointed to the Board in November of fiscal year 2021 and received pro rata compensation. Each of Messrs. Stone and Francis accepted $20,000 of the $50,000 additional annual cash retainer for the Lead Director, which was paid on a pro rata basis for the portions of fiscal year 2021 during which each served as Lead Director. Therefore, pro rata payments were made to Mr. Stone of $15,000 for his service through September of fiscal year 2021 and to Mr. Francis of $5,000 for his service for the remainder of fiscal year 2021.

COMPENSATION DISCUSSION AND ANALYSIS 3 1 2 4 5 initiatives to create new Compensation Philosophy and Objectives The program provides a market-competitive base salary and short-and long-term incentive compensation components that are earned primarily based on performance. The Compensation Committee regularly reviews the named executive officer compensation program to ensure the fulfillment of our compensation philosophy and goals. The key principles and objectives underlying our compensation philosophy are the following: A significant portion of total compensation should be at risk or performance-based, including a portion dependent upon the attainment of specific and measurable annual and long-term performance objectives. Key elements of compensation should be designed to create long-term value for our stockholders, as well as foster a culture of ownership. Target annual compensation should be competitive with that being offered to individuals holding comparable positions at other companies in our industry peer group and target market. The Company must attract, motivate and retain highly-talented people with exceptional leadership capabilities.

COMPENSATION DISCUSSION AND ANALYSIS While remaining flexible to achieve its overall philosophy, the Compensation Committee utilizes peer group data (for the Chief Executive Officer and Chief Financial Officer) and a combination of peer group and industry survey data (for the other named executive officers) to benchmark target annual compensation, with each compensation component varying from such market positioning based on individual experience, skills, capabilities and knowledge, as well as internal pay equity and internal promotions. Key Elements of Fiscal Year 2021 Compensation The following table sets forth how each component of fiscal year 2021 compensation was intended to satisfy one or more of the key principles and objectives underlying our compensation philosophy. strategy and short-term strategy with stock as the special grant of PSUs made to the other over the eight fiscal quarters financial performance stockholders Ongoing Responsiveness to Significant Fiscal Year 2020 Stockholder Engagement As a direct result of the targeted stockholder outreach, the Compensation Committee expedited the shift of the Company’s compensation structure from a private-equity sponsor model to a mature public company model. Although planned progress was delayed in part in fiscal year 2021 due to the COVID-19 pandemic, the fundamental changes implemented for our executive compensation program in fiscal years 2021 and 2022 reflect our Board’s desire to learn from and work with long-term stockholders to achieve success for the Company and its stakeholders.

COMPENSATION DISCUSSION AND ANALYSIS Key Features of Target and Actual Compensation in Fiscal Year 2021 to uncertainty from the COVID-19 pandemic and therefore may not have served the AT HOME GROUP INC. 2021 PROXY STATEMENT 36 Base Salary—3-month salary reduction due to COVID-19 • Mr. Bird—No increase from fiscal year 2020, and an effective 50% voluntary reduction for a three-month period when home office employees were either furloughed or received reduced salaries. • Three named executive officers received increases ranging from 7% to 17% primarily based on benchmarking and additional job responsibilities. • All named executive officers volunteered a 30% reduction for the same three-month period of Mr. Bird’s voluntary reduction. Bonus—Revised performance metrics and strong fiscal year 2021 performance • Consistent with all bonus-eligible home office employees, all named executive officers received 200% of their bonus target due to greater than maximum performance for the management bonus plan metrics (adjusted operating income and total sales growth), with no effective adjustments made to performance goals approved in early fiscal year 2021 based on the Board-approved budget. In fiscal years 2020 and 2019, all named executive officers received 0% and 100.7% of their bonus targets, respectively. • The fiscal year 2021 management bonus plan had been developed before the COVID-19 pandemic began to significantly impact the U.S. economy and our operations. In June of fiscal year 2021, the Compensation Committee replaced the management bonus plan with a discretionary bonus plan due to the significant impact of the COVID-19 pandemic on our business. Under the discretionary bonus plan, management bonuses were intended to be based on the overall performance of the Company as well as qualitative and operational measures for the first two quarters of fiscal year 2021, with additional quantitative considerations for the last two quarters of fiscal year 2021. In August of fiscal year 2021, following the reopening of our stores and overall improved performance, the Compensation Committee determined to reinstate the fiscal year 2021 management bonus plan in the same form previously approved prior to the pandemic, including the adoption of two new performance metrics, equally weighted, adjusted operating income and total sales growth, with performance goals for each metric based on the Company’s original Board-approved budget for fiscal year 2021. Equity—Focused on stock options due to difficulty in setting PSU performance goals • Named executive officers received 100% stock options for annual equity awards. The Compensation Committee considered that options deliver value to the holder that is aligned with stockholder return but, unlike PSUs, did not require the Compensation Committee to set objective performance goals, which were very difficult to establish due intended retention and incentive purposes. • Mr. Bird also received a special grant of PSUs that had the same terms as the special grant of PSUs made to the other named executive officers in fiscal year 2020, which further aligned the executive team to achieve two long-term performance metrics linked to the Company’s business strategy and long-term profitability, comparable store sales growth and adjusted net income growth.

Mr. Bird has the most involvement in, and knowledge of, the Company’s business goals, strategies and performance, the overall effectiveness of our management team and each person’s individual contribution to the Company’s performance. Other key leaders also provide valuable context for the Company’s human capital management efforts as well as an understanding of peer and general market practices regarding compensation. For each named executive officer other than Mr. Bird, Mr. Bird presents a compensation recommendation, which is reviewed by the Chairperson of the Compensation Committee and presented to such Committee. No person provides input with respect to his or her own compensation. Management also provides the Committee with information regarding the individual’s experience, current performance, potential for advancement and other subjective factors. The Committee reviews management recommendations for their reasonableness based on individual and Company performance as well as peer and market information. The Compensation Committee works with management to set the agenda for Committee meetings, and Mr. Bird is invited regularly to attend such meetings as well as our Chief Administrative Officer and General Counsel and Chief Human Resources Officer. Independent Compensation Consultant The Compensation Committee determined to re-engage Pearl Meyer as its independent compensation consultant for fiscal year 2021 and approved the terms of the engagement. Representatives of Pearl Meyer may attend certain Compensation Committee meetings. Among other matters, Pearl Meyer provided recommendations on an appropriate peer group and peer group benchmarking regarding target annual compensation for all named executive officers, as well as detailed information on alternatives for the design and implementation of the named executive officer compensation program. Pearl Meyer also advises the Committee in establishing the target annual compensation of Mr. Bird, and provided recommendations on inducements for new executive officers. AT HOME GROUP INC. 2021 PROXY STATEMENT 37 What We Don’t Do What We Do

COMPENSATION DISCUSSION AND ANALYSIS Fiscal Year 2021 Peer Group Based on the advice of Pearl Meyer and members’ extensive experience with compensation practices in other businesses, the Compensation Committee established the peer group for purposes of benchmarking the fiscal year 2021 compensation of the named executive officers. The Compensation Committee reviewed the peer group companies based on objective factors, including industry and revenue, and subjective factors, including business model and competition for talent, and considered the range and median of revenue and market capitalization represented by the peer companies to be appropriate given the Company’s focus on recruiting, motivating and retaining top talent. The peer group has been reviewed annually by the Compensation Committee in recent years due to the Company’s significant growth. The Compensation Committee determined to maintain the fiscal year 2020 peer group for fiscal year 2021 benchmarking. The following companies were utilized for purposes of benchmarking the fiscal year 2021 compensation of the named executive officers. • Aaron’s Inc. • Floor & Decor Holdings, Inc. • Party City Holdco Inc. • Carters Inc. • Haverty Furniture Companies, Inc. • RH • Chico’s FAS, Inc. • Herman Miller, Inc. • The Michaels Companies, Inc. • Designer Brands Inc. • La-Z-Boy Incorporated • Ulta Beauty, Inc. • Five Below, Inc. • Ollie’s Bargain Outlet Holdings, Inc. • Williams-Sonoma, Inc. For fiscal year 2021, compensation decisions for the Chief Executive Officer and Chief Financial Officer were evaluated using peer group benchmarking, while the Compensation Committee referenced a combination of peer group data and general survey data in evaluating compensation for the other named executive officers. FISCAL YEAR 2021 COMPENSATION PROGRAM AND DETERMINATIONS We compensate our named executive officers through a combination of base salary, annual cash bonuses, sign-on bonuses, long-term equity incentives and other benefits as described below. Base Salary—Targeted Increases for Certain Persons; Voluntary 3-Month Salary Reduction Due to Pandemic-Related Matters Base salaries are reviewed by the Compensation Committee on an annual basis. The Compensation Committee determined to increase base salaries for Mr. Knudson and Mr. Stauffer to more closely align with our benchmarking data and for Mr. Corsa to reflect his expanded responsibilities in fiscal year 2021 for real estate, information technology and oversight of strategy. The base salaries of our named executive officers other than Mr. Bird were temporarily reduced by 30% for three months in fiscal year 2021 during the time period when our home office employees were either furloughed or received reduced salaries. During the same period, Mr. Bird initially elected to forgo 100% of his base salary. However, in January 2021, the Compensation Committee determined that the 100% salary reduction for Mr. Bird for such period was unnecessary in light of Company performance and liquidity and approved a supplemental payment of $125,000 to Mr. Bird, to be paid simultaneously with annual cash bonuses. Such payment was intended to adjust his aggregate cash compensation to effectively reflect a 50% reduction in his base salary during the three-month reduction period and more closely align his base salary reduction with the three-month salary reduction of 30% taken by the Company’s other named executive officers.

Management Bonus Plan—Two New Performance Metrics; Strong Performance in Fiscal Year 2021 Establishing Bonus Target Bonus targets are set as percentages of base salaries. The earned bonus is determined by the bonus target in dollars multiplied by a multiplier of 0-200% based on achievement of performance metrics. The Compensation Committee determined not to change the bonus target for each named executive officer (as a percentage of base salary) for fiscal year 2021. In recent years, bonus targets and payment amounts were based on the base salary actually paid in such fiscal year. However, the base salary utilized for the fiscal year 2021 bonus determinations for all participants, including the named executive officers, was based on the wages that would have been paid to such persons during fiscal year 2021 excluding the impact of any salary reduction or furlough in effect in fiscal year 2021. The Compensation Committee wanted to avoid twice penalizing bonus participants for the prudent expense and cash management determinations made earlier in fiscal year 2021, particularly due to the Company’s strong financial and operating performance for fiscal year 2021 and the Company’s liquidity. The following table sets forth the target bonuses, as a dollar value and as a percentage of base salary, for the named executive officers in fiscal year 2021. Lewis L.

COMPENSATION DISCUSSION AND ANALYSIS Performance Metrics In recent years, the Compensation Committee utilized adjusted earnings before interest, taxes, depreciation and amortization (adjusted EBITDA) and comparable store sales growth as the two Company performance metrics to earn a bonus under the management bonus plan. For fiscal year 2021, the Compensation Committee revised the Company performance metrics to earn a bonus under the fiscal year 2021 management bonus plan as set forth below. Management and the Board use these performance metrics to assess the Company’s performance, to evaluate the effectiveness of business strategies, to make budgeting decisions and to compare the Company’s performance against that of other peer companies using similar measures. The Compensation Committee utilizes the same definition of adjusted operating income and total sales growth as is used for purposes of the Company’s earnings presentations furnished to stockholders. The Compensation Committee established performance goals for each metric based on the Company’s original Board-approved budget for fiscal year 2021 and it did not make any adjustments for final bonus determinations. The Board approved the performance goals before the COVID-19 pandemic began to significantly impact the U.S. economy and our operations. The following table presents the threshold, target and maximum performance goals and related achievement multiples, together with actual performance for fiscal year 2021. Threshold Performance 50% $80.3 million 50% 10.8% Target Performance 100% $89.2 million 100% 13.5% Maximum Performance 200% $102.6 million 200% 16.3% * For both components, there was a linear increase in the achievement multiple between threshold and target performance, and a separate but linear increase in the achievement multiple between target and maximum performance.

COMPENSATION DISCUSSION AND ANALYSIS Equity Awards The named executive officers received the following equity awards described above in fiscal year 2021: Lewis L. Bird III 80,000 890,000 Jeffrey R. Knudson — 180,000 Peter S.G. Corsa — 230,000 Chad C. Stauffer — 190,000 Ashley F. Sheetz — 100,000 (1) The annual awards for the named executive officers were granted on June 22, 2020. Annual Equity Award Program Beginning in fiscal year 2019, the Board determined to implement an annual equity award program for executive officers and other key employees, other than Mr. Bird, to support incentive and retention objectives. In fiscal years 2019 and 2020, the annual equity program included the grant of RSUs (25%) and nonqualified stock options (75%). In fiscal year 2021, the Compensation Committee intended to increase the program’s emphasis on at-risk and performance-based compensation through a mix of PSUs, RSUs and stock options; however, before the Compensation Committee finalized the fiscal year 2021 compensation program, the COVID-19 pandemic began to significantly impact the U.S. economy and our operations, and the Compensation Committee determined to maintain flexibility and defer a decision regarding the timing and structure of annual equity awards. In June of fiscal year 2021, the Compensation Committee determined that the fiscal year 2021 annual equity awards for the named executive officers would consist entirely of stock options. The Compensation Committee considered that options deliver value to the holder that is aligned with stockholder return but, unlike PSUs, did not require the Compensation Committee to set objective performance goals, which were very difficult to establish due to uncertainty from the COVID-19 pandemic and therefore may not have served the intended retention and incentive purposes. The stock options vest in equal installments on each of the first three anniversaries of the applicable grant date, subject to the participant’s continued employment through each vesting date. In prior years, the aggregate target dollar value of the annual awards was individually determined for each named executive officer, taking into account each officer’s length of service and performance, the amount and retentive value of the vested and unvested equity currently held by each officer and benchmarking data provided by Pearl Meyer. For fiscal year 2021 the Compensation Committee recognized that a limited number of shares were available for issuance under the 2016 Equity Plan, in particular due to the comparatively low trading price of the Company’s common stock at the time. The Compensation Committee sought to limit the size of fiscal year 2021 awards to ensure that there would be sufficient shares available under the 2016 Equity Plan to grant annual awards to executive officers, directors and employees for fiscal year 2022 as well. Accordingly, the Compensation Committee allocated the total number of shares available for grants to executive officers and to non-executive employees between fiscal years 2021 and 2022, and then allocated a portion of such shares for fiscal year 2021 grants to executive officers. Thereafter, the Compensation Committee targeted a specific share number for each executive officer’s annual equity award based on the proportionate equity allocation to such officers in March 2019.

COMPENSATION DISCUSSION AND ANALYSIS Special Equity Award—CEO In addition to the annual equity award, Mr. Bird received a special grant of PSUs, which had the same terms as the special grant of PSUs made to the Company’s other named executive officers in fiscal year 2020 as retention performance awards, which furthers the alignment of management to achieve such performance metrics. This grant also addressed the Compensation Committee’s concern that Mr. Bird had no unvested equity and all of his vested stock options were underwater. The PSUs vest based on achievement of the following two performance metrics. The performance metrics are defined in the same manner as such terms are used for purposes of the Company’s earnings releases furnished to stockholders. Management and the Board use these performance metrics to assess the Company’s performance, to evaluate the effectiveness of business strategies, to make budgeting decisions and to compare the Company’s performance against that of other peer companies using similar measures. The achievement multiple for the performance components is: Threshold Performance 50% Target Performance 100% Maximum Performance 200% For both components, there is a linear increase in the achievement multiple between threshold and target performance, and a separate but linear increase in the achievement multiple between target and maximum performance. Vesting also is subject to the participant’s continued employment through the end of the performance period. AT HOME GROUP INC. 2021 PROXY STATEMENT 42 Percentage expansion of 50% of the Adjusted Net Income over target award the eight fiscal quarters ending on January 29, 2022 Defined as net (loss) income, adjusted for impairment charges, gain on sale-leaseback, IPO related non-cash stock-based compensation expense and related payroll tax expenses and the income tax impact associated with the special one-time IPO bonus stock option exercises, non-cash stock-based compensation expense related to the CEO Special Option Grant and the deferred tax expense related to the cancellation thereof, costs associated with the resignation of our former Chief Financial Officer, costs associated with the restructuring of our merchandising department and other adjustments, which include costs related to the registration and sale of shares of our common stock on behalf of certain existing stockholders, other transaction costs and other items we do not believe are indicative of our core operating performance. Comparable store sales 50% of the growth over the eight fiscal target award quarters ending on January 29, 2022 Defined as the change in period-over-period net sales for the comparable store base, beginning with stores on the first day of the sixteenth full fiscal month following the store’s opening. When a store is being relocated or remodeled, the Company excludes sales from that store in the calculation of comparable store sales until the first day of the sixteenth full fiscal month after it reopens. Comparable store sales growth refers to the sum of the increase in comparable store sales for each of the current and preceding fiscal years.

COMPENSATION DISCUSSION AND ANALYSIS Performance of Unearned PSUs as of January 30, 2021 The Compensation Committee periodically reviews estimated payouts of unearned PSU awards to understand the current incentive and retentive value of such awards, which may impact its decisions on current year equity awards. The estimated achievement multiple for the PSU awards granted to Mr. Bird in fiscal year 2021 and to the other named executive officers in fiscal year 2020 are shown in the table below based on the four fiscal quarters ended January 30, 2021. Percentage expansion of Adjusted Net Income (50% of target award) Eight fiscal quarters ending on January 29, 2022 200% Comparable store sales growth (50% of target award) Eight fiscal quarters ending on January 29, 2022 200% Therefore, as of January 30, 2021, the estimated payout for such PSU awards was 200% of the target PSU awards. Actual payout will be determined based on Company performance for the eight fiscal quarters ending on January 29, 2022, and the estimated payout may not be indicative of actual payout. Other Annual Compensation and Benefits Perquisites The Company provided each named executive officer with perquisites to indirectly benefit the Company, including a financial planning allowance, an annual wellness exam (with a tax-gross up) and new-hire relocation benefits (with a tax-gross up). The Compensation Committee believes these benefits are competitive with similarly situated peer companies and are appropriately limited. 401(k) Plan The Company maintains, and the named executive officers participate in, a tax-qualified 401(k) retirement savings plan. Each participant may contribute to the plan through payroll deductions, up to 100% of his or her salary and bonus limited to the maximum allowed by the Internal Revenue Service regulations. The Company provided employer “safe harbor” matching contributions to all participants, including the named executive officers, equal to 100% of salary deferrals up to 3% of a participant’s compensation and 50% of salary deferrals thereafter up to 5% of a participant’s compensation. Employment Agreements and Termination Benefits The Company generally enters into employment agreements with our named executive officers that provide for specified payments in connection with certain termination events. The Compensation Committee believes that these arrangements improve our ability to attract and retain qualified executives by guaranteeing certain compensation in the initial year of hiring, as well as severance benefits to provide job security for the long-term. In consideration for such benefits, the Company benefits from obtaining non-competition, non-solicitation and confidentiality protections. In addition, our incentive programs provide certain severance benefits in connection with certain termination events. See “Potential Payments Upon Termination or Change in Control as of January 30, 2021” for additional information.

COMPENSATION DISCUSSION AND ANALYSIS OTHER EQUITY-RELATED POLICIES Executive Officer Equity Ownership Guidelines The Compensation Committee adopted executive officer equity ownership guidelines in February 2019 to further align the interests of stockholders and executives. Under such guidelines, executive officers are expected to achieve and maintain ownership of equity with a total value equal to a multiple of such executive’s base salary as follows: Chief Executive Officer • • • • • 5x Chief Operating, Financial and Merchandising Officer • • 2x All Other Executive Officers • 1x Executives are expected to initially satisfy such guidelines within a five-year initial compliance period. As of the Record Date, all executive officers in service were either in compliance with the guidelines or within the compliance period and making appropriate progress. The current guidelines are available on our website at investor.athome.com. Timing and Pricing of Equity-Based Grants The Compensation Committee and the Board do not coordinate the timing of equity-based grants to executive officers with the release of material non-public information. Annual equity grants generally are made in the first quarter of each fiscal year during an open window period, and new hire equity grants generally are made as of the hire date. The exercise price of each option award is the closing price for the Company’s common stock on the date approved by the Compensation Committee or the Board to be the grant date (which date is not earlier than the date the Compensation Committee or the Board approved such grant). Securities Trading Policy—No Pledging or Hedging for Directors and Executive Officers Our Securities Trading Policy is designed to create reasonable processes to prevent the Company and its directors, officers, employees and specified other persons from insider trading and any appearance of improper conduct. Our Securities Trading Policy specifically prohibits, among other things, all directors and executive officers of the Company (but not all employees) from effecting hedging transactions (such as short sales, put options, call options or other derivative securities and including through the use of financial instruments such as prepaid variable forward contracts, equity swaps, collars and exchange funds) or holding securities in a margin account or otherwise pledging securities as collateral for a loan or hedging or similar monetization related to the Company’s securities. Clawback Policy for Executive Officers In the event that the Board or a committee determines that any fraud, negligence or intentional misconduct by a current or former executive officer of the Company (who was serving as executive officer on or after the policy’s adoption date) was a significant contributing factor to the Company having to restate all or a portion of its financial statements, our clawback policy empowers the Board or committee to seek recovery of any cash or equity-based incentive compensation granted, earned or paid to such executive officer of the Company and to prevent the recurrence of such fraud, negligence or intentional misconduct to the fullest extent permitted by governing law. The Board or committee thereof has discretion whether to seek recoupment taking into account any factors deemed appropriate.

COMPENSATION DISCUSSION AND ANALYSIS TAX AND ACCOUNTING IMPLICATIONS Deductibility of Executive Compensation Section 162(m) of the Internal Revenue Code of 1986, as amended (the “Code”) generally prohibits public companies from taking a tax deduction for compensation paid in excess of $1,000,000 to certain executive officers. Prior to its amendment as implemented by the Tax Cuts and Jobs Act of 2017 (the “Tax Act”), Section 162(m) of the Code provided an exception from the compensation deduction limitations for compensation that was considered “qualified performance-based compensation” under the applicable regulations. Section 162(m) of the Code also provides that a company that becomes public in connection with an IPO is exempt from applying the compensation deduction limitations for a specified period of time following its IPO (the “IPO Transition Period”). The Tax Act’s amendment of Section 162(m) of the Code, among other things, eliminated, beginning in 2018, the exception to the compensation deduction limitations for “qualified performance-based compensation,” other than in limited circumstances. The IPO Transition Period for an IPO effectuated prior to December 20, 2019, was not impacted by the Tax Act’s amendments to Section 162(m) of the Code. The Company completed its IPO in August 2016 and operated within its IPO Transition Period with respect to its management bonus plan until it expired on the date of our first stockholder meeting at which directors were elected during the 2020 calendar year. The IPO Transition Period with respect to the 2016 Equity Plan ended in fiscal year 2019. While the management bonus plan and the 2016 Equity Plan currently include certain provisions that had been intended to allow the Compensation Committee, following the expiration of the Company’s IPO Transition Period, to grant awards that could be considered “qualified performance-based compensation” for purposes of Section 162(m) of the Code, the Tax Act’s amendments to Section 162(m) of the Code have made these provisions inapplicable for such purposes. Accordingly, any bonuses paid under the management bonus plan or performance awards granted under the 2016 Equity Plan to employees covered by Section 162(m) of the Code, as amended, will be subject to the compensation deduction limitations set forth in Section 162(m) of the Code. Although the management bonus plan and the 2016 Equity Plan were designed with tax considerations in mind, the Compensation Committee retains the flexibility to authorize compensation that may not be deductible if the Compensation Committee believes doing so is in the best interests of the Company. Nonqualified Deferred Compensation Section 409A of the Code generally imposes an additional 20% income tax, as well as interest and penalties, on recipients of deferred compensation that does not comply with Section 409A of the Code. “Deferred compensation” for this purpose generally consists of compensation to which an individual has a legally binding right in a taxable year and which is to be paid in a later taxable year. In addition to the taxes, interest and penalties, deferred compensation that does not comply with Section 409A of the Code may be required to be taken into income earlier than is intended. The Company believes that its compensation arrangements comply with, or are exempt from, the requirements of Section 409A. Change in Control Payments If a company makes “parachute payments”, Section 280G of the Code prohibits the company from deducting the portion of the parachute payments constituting “excess parachute payments” and Section 4999 of the Code imposes on a “disqualified individual” a 20% excise tax on the excess parachute payments. For this purpose, parachute payments generally are defined as payments to disqualified individuals that are contingent upon a change in control in an amount equal to or greater than three times the disqualified individual’s base amount (i.e., in general, the five-year average Form W-2 compensation). The excess parachute payments, which are nondeductible and subject to a 20% excise tax, equal the portion of the parachute payments that exceeds one times the disqualified individual’s base amount. Each of the named executive officers has an employment agreement with the Company that entitles him or her to payments upon the termination of his or her employment, including in connection with a change of control that may qualify as excess parachute payments. The 2016 Equity Plan may entitle participants to payments in connection with a change in control that may result in excess parachute payments. In accordance with Mr. Bird’s employment agreement and the equity award agreements with each of the other named executive officers, if any payments or benefits to which he or she would be entitled to receive pursuant to the terms of the applicable agreement or otherwise in connection with a change in the ownership or effective control of the Company would result in all or a portion of such payments or benefits being deemed “parachute payments” under Section 280G of the Code and the excise tax imposed by Section 4999 of the Code, such AT HOME GROUP INC. 2021 PROXY STATEMENT 45

COMPENSATION DISCUSSION AND ANALYSIS payments and benefits will be reduced to the minimum extent necessary so that they would not result in the imposition of an excise tax under Section 4999 of the Code, provided that no reduction will be made if the named executive officer would receive a greater net after-tax amount absent such reduction. Other The Company does not pay tax gross-ups or other reimbursement payments with respect to the excise tax imposed on any person as a result of the application of Sections 4999 or 409A of the Code.

NAMED EXECUTIVE OFFICER COMPENSATION TABLES NARRATIVE DISCLOSURE TO SUMMARY COMPENSATION TABLE AND GRANTS OF PLAN-BASED AWARDS TABLE Elements of Compensation We compensate our named executive officers through a combination of base salary, sign-on bonuses, cash incentives, annual and special long-term equity incentives, and other benefits. See “Compensation Discussion and Analysis” for a discussion for fiscal year 2021 compensation matters, including the material terms of the fiscal year 2021 equity awards to the named executive officers. Stock and Option Awards in Fiscal Years 2019 and 2020 CEO Special Option Award in Fiscal Year 2019—Cancelled in Fiscal Year 2020 In lieu of participation in the annual equity program and the transition equity awards noted below, the Board granted stock options to purchase 1,988,255 shares of stock to Mr. Bird in fiscal year 2019. The nonqualified stock options vested immediately on the grant date and had a seven-year term, and the shares resulting from the exercise of the stock options were generally subject to transfer restrictions that lapsed on the fourth or eighth anniversary of the grant date based on certain service conditions. Following the low support for Say-on-Pay at our 2019 annual meeting of stockholders, at Mr. Bird’s request and agreed to by the Compensation Committee, the Company cancelled this option for no consideration pursuant to an option cancellation agreement. Annual Awards in Fiscal Years 2019 and 2020—RSUs and Stock Options In fiscal years 2019 and 2020, the Compensation Committee implemented an annual equity grant program for executive officers and other key employees, other than Mr. Bird, consisting of service-based RSUs (25%) and nonqualified stock options (75%) that vest in equal installments on each of the first three anniversaries of the grant date. Special Awards in Fiscal Year 2019—Stock Options In fiscal year 2019, to assist in retention in connection with the transition from the historical use of special equity grants to an annual equity program, the Board granted special service-based, nonqualified stock option awards to executive officers and other key employees, other than Mr. Bird, that vest in equal installments on each of the third and fourth anniversaries of the grant date. Special Retention Awards in Fiscal Year 2020—PSUs and Options Due to the decline in the Company’s stock price during fiscal year 2020 and the retention risk resulting from substantially all stock options held by the named executive officers being out-of-the-money, in fiscal year 2020, the Compensation Committee granted a special equity award to executive officers and other key employees, other than Mr. Bird, consisting of PSUs and nonqualified stock options. The stock options vest in full on January 29, 2022. The PSUs are earned and vest based on achievement of comparable store sales growth (50%) and percentage expansion of Adjusted Net Income (50%) over the eight fiscal quarters ending on January 29, 2022. The number of shares, if any, deliverable upon settlement of the PSUs for each metric will equal 50% to 200% of the target award based on the achievement of threshold and maximum performance, respectively, with a linear increase in the achievement multiple between threshold and target performance, and a separate but linear increase in the achievement multiple between target and maximum performance. Material Modification in Fiscal Year 2019 to Certain Equity Awards See “Potential Payments Upon Termination or Change in Control as of January 30, 2021” for a description of an amendment to the fiscal year 2019 equity awards to the named executive officers (except Mr. Bird) regarding accelerated vesting for a change in control. AT HOME GROUP INC. 2021 PROXY STATEMENT 50

NAMED EXECUTIVE OFFICER COMPENSATION TABLES Non-Equity Incentive Plan Compensation Bonus targets are set as percentages of base salaries, and the earned bonus is determined by the bonus target in dollars multiplied by a multiplier of 0-200% based on achievement of performance metrics. In fiscal years 2019 and 2020, the Company performance metrics were: (i)adjusted EBITDA versus the financial plan for the fiscal year, which comprised 75% of the target bonus, and (ii) comparable store sales growth versus the financial plan for the fiscal year, which comprised 25% of the target bonus. The earned multiplier for bonuses in fiscal years 2019 and 2020 were 100.7% and 0% in the aggregate, respectively. For fiscal year 2019, Mr. Stauffer’s target bonus was prorated for fiscal year 2020 so that a rate of 50% of his base salary was applied prior to his promotion and a rate of 70% of his base salary was applied following his promotion. Employment Agreements During fiscal year 2021, the Company was party to employment agreements with each of the named executive officers. Each employment agreement continues for an indefinite term, subject to termination by either party, other than for Cause (as defined below), upon prior written notice, as set forth in the applicable agreement. In addition, each agreement provides that such named executive officer is eligible to participate in all benefit programs for which other senior executives of the Company are generally eligible. See “Potential Payments Upon Termination or Change in Control as of January 30, 2021” for a description of the material terms of the employment agreements that provide for specified payments in connection with certain termination events.

Employment Agreements with Continuing Named Executive Officers Each named executive officer was party to an employment agreement as of January 30, 2021 that provides for specified payments in connection with certain termination events. For additional information on the material terms of the employment agreements, see “Named Executive Officer Compensation Tables—Narrative Disclosure to Summary Compensation Table and Grants of Plan-Based Awards Table.” Accrued Amounts Upon any termination of employment, each of the named executive officers is entitled to payment of any earned but unpaid base salary, accrued but unused paid time off (if required by applicable law to be paid upon termination), vested benefits in accordance with the applicable employee benefit plan and unreimbursed business expenses. Accrued Bonus—Mr. Bird, Mr. Corsa and Ms. Sheetz Except for terminations by the Company for Cause, each of Mr. Bird, Mr. Corsa and Ms. Sheetz are entitled to any earned but unpaid annual bonus for a fiscal year completed prior to the termination date. Further, upon any termination of Mr. Bird’s employment, other than for Cause or due to resignation without Good Reason (as defined below), that occurs after the 90th day of a fiscal year, Mr. Bird is entitled to a pro rata bonus for the year of termination based on performance through the end of the month preceding termination and an adjusted performance target, prorated based on the number of days worked in the fiscal year of termination.

NAMED EXECUTIVE OFFICER COMPENSATION TABLES Restrictive Covenants Each employment agreement includes restrictive covenants providing for non-competition, non-solicitation of employees, and non-interference with business relationships, in each case during employment and for one year thereafter, as well as requirements regarding mutual non-disparagement and nondisclosure of confidential information. In the event the executive breaches any of these restrictive covenants, the executive will be required to return to the Company any portion of severance amounts paid by the Company to the executive and forfeit any future amounts due. In addition, each employment agreement requires that the employee deliver an irrevocable release of claims to receive such severance. Tax Matters In accordance with Mr. Bird’s employment agreement and the equity award agreements with each of the other named executive officers, if any payments or benefits to which the applicable named executive officer would be entitled to receive pursuant to the terms of the applicable agreement or otherwise in connection with a change in the ownership or effective control of the Company would result in all or a portion of such payments or benefits being deemed “parachute payments” under Section 280G of the Code and the excise tax imposed by Section 4999 of the Code, such payments and benefits will be reduced to the minimum extent necessary so that they would not result in the imposition of an excise tax under Section 4999 of the Code, provided that no reduction will be made if the named executive officer would receive a greater net after-tax amount absent such reduction. Defined Terms “Cause” under each employment agreement is generally defined as any one of the following: • Willful misconduct or gross negligence in the performance of, or refusal or intentional failure to perform, any of the employee’s assigned duties to the Company. The commission or conviction (including conviction upon of a plea of nolo contendere) of a felony or other crime involving fraud, theft, breach of trust or similar acts. Any failure to comply with any written rules, regulations, policies or procedures of the Company which, if not complied with, would reasonably be expected to have a material adverse effect on the business or financial condition of the Company. Any misconduct that would cause the Company to violate any law relating to sexual harassment or age, sex or other prohibited discrimination. • • • “Good Reason” under each employment agreement is generally defined as any one of the following: • • • • A material breach by the Company of any of the covenants in the employment agreement. Any material reduction in the employee’s base salary or compensation. Any material and adverse change in the employee’s position, title or status. Any change in the employee’s job duties, authority or responsibilities to those of lesser status. “Change of Control” under Mr. Bird’s employment agreement is generally defined as any one of the following: • • Sale of all or substantially all of the assets of the Company; or A sale by the Company, GRD Holding LP or any entity controlled by AEA, or a merger, consolidation or similar transaction involving the Company, that results in more than 50% of the Company’s common stock being held by a person that is not an affiliate or AEA.

NAMED EXECUTIVE OFFICER COMPENSATION TABLES Outstanding Awards Under the 2016 Equity Plan As a general matter, the Compensation Committee has discretion under the 2016 Equity Plan to determine the time or times at which awards may be granted, the recipients of awards and the performance criteria, performance goals and all other terms of an award. The terms of the various award agreements granted under the 2016 Equity Plan provide for accelerated vesting upon the occurrence of certain events. Other named executive officers refer to all named executive officers except Mr. Bird. IPO Option Awards—Mr. Bird If Mr. Bird has a termination of service due to death, disability or a Severance Event (as defined in his award agreement), the vested portion of his IPO Options will expire on the seventh anniversary of the date of grant. If he has a termination for Cause, then his IPO Options will be forfeited immediately upon the effective date of such termination. Stock Options—Other Named Executive Officers If a named executive officer has a termination of service without Cause, other than due to death or disability, the vested portion of the award will expire 90 days (subject to extension if all or a portion of such period is during a time that the stock options may not be exercised due to applicable law, a blackout period, a lock-up arrangement or similar circumstance) following such termination or, if earlier, the termination date of the option (the seventh anniversary of the grant date or, for stock options granted in 2014, the tenth anniversary of the grant date). If a named executive officer has a termination of service due to death or disability, the vested portion of the award will expire on the first day that is one year after the termination date, or, if earlier, the seventh anniversary of the grant date. If a named executive officer is terminated for Cause, then such award will be forfeited immediately upon the effective date of such termination. If the named executive officer is terminated for any reason other than Cause, the unvested portion of the award will be forfeited immediately upon the termination date. RSUs If a named executive officer has a termination of service for any reason, whether voluntarily or involuntarily, then the unvested portion of such award will terminate as of the termination date. If the named executive officer is terminated for Cause, then the RSUs (whether or not vested) will be forfeited immediately and terminated without consideration upon the date of termination for Cause. PSUs If a named executive officer remains employed through a Change in Control that occurs prior to the end of the performance period, the number of PSUs that would have vested based on the greater of actual performance determined as of the date of such Change in Control or target performance, will remain issued and outstanding and eligible to vest subject only to the grantee’s continued employment with the Company through January 29, 2022 or an earlier termination without Cause or resignation for Good Reason (each as defined in the award agreement) that occurs within one year following consummation of the Change in Control.

NAMED EXECUTIVE OFFICER COMPENSATION TABLES Right to Terminate Stock Options and Recovery Each award granted under the 2016 Equity Plan provides that the Company may terminate, without consideration, the award (including any vested portions of the award) if the executive: (a) materially violates any of his or her obligations under any agreement between the Company and the executive relating to any of the following: (i) the non-disclosure or non-use of confidential or proprietary information; (ii) non-disparagement of the Company; (iii) restrictions on the transfer of any awards; (iv) non-solicitation of Company employees; and (v) non-competition; or (b) is convicted of a felony against the Company or any of its affiliates. Fiscal Years 2019, 2020 and 2021 Awards—Change in Control The fiscal year 2019 stock option and RSU agreements were amended by the Board on June 7, 2018 to provide for accelerated vesting upon a termination without Cause or resignation for Good Reason (each as defined in the applicable award agreements) within one year of a Change in Control. The fiscal year 2020 and 2021 stock option and RSU agreements, including for the fiscal year 2021 stock options granted to Mr. Bird, also provide for accelerated vesting upon a termination without Cause or resignation for Good Reason within one year of a Change in Control. The special transition option awards granted in fiscal year 2019 that vest in equal annual installments on each of the third and fourth anniversaries of the grant date also were amended by the Board on June 7, 2018 to provide for accelerated vesting upon the consummation of a Change in Control, regardless of termination of service, subject to continued employment through such date. Fiscal Years 2021 Stock Options—Other Named Executive Officers Under the stock option agreements for the awards granted in fiscal year 2021 to our named executive officers, other than Mr. Bird, if a named executive officer has a termination of service due to Qualifying Retirement (other than for Good Reason within one year following the consummation of a Change in Control) the portion of the stock option that would have vested during the twelve-month period following such Qualifying Retirement but for such Qualifying Retirement will not terminate as a result of such Qualifying Retirement and will vest and become exercisable on the date such portion of the stock option otherwise would have vested and become exercisable but for such Qualifying Retirement and the vested portion of the award will expire on the first day that is one year after the post-retirement vesting period, or, if earlier, the seventh anniversary of the grant date. “Qualifying Retirement” means voluntary resignation that occurs at least six months following the date of grant after attaining a combination of 55 years of age with at least 10 years of service if grounds for Cause did not exist at the time of such termination. None of the named executive officers was eligible for a Qualifying Retirement if his or her retirement occurred as of January 30, 2021. AT HOME GROUP INC. 2021 PROXY STATEMENT 58

NAMED EXECUTIVE OFFICER COMPENSATION TABLES Change in Control—Defined For purposes of the 2016 Equity Plan, “Change in Control” generally means the occurrence of any of the following events with respect to the Company: • Any person (other than directly from the Company) first acquires securities of the Company representing fifty percent or more of the combined voting power of the Company’s then outstanding voting securities, other than an acquisition by certain employee benefit plans, the Company or a related entity or any person in connection with a non-control transaction. A majority of the members of the Board is replaced by directors whose appointment or election is not endorsed by a majority of the members of the Board serving immediately prior to such appointment or election. Any merger, consolidation or reorganization, other than in a non-control transaction. • • • • A complete liquidation or dissolution. Sale or disposition of all or substantially all of the assets. A “non-control transaction” generally includes any transaction in which: • Stockholders immediately before such transaction continue to own at least a majority of the combined voting power of such resulting entity following the transaction; A majority of the members of the Board immediately before such transaction continue to constitute at least a majority of the board of the surviving entity following such transaction; or • • With certain exceptions, no person other than any person who had beneficial ownership of more than fifty percent of the combined voting power of the Company’s then outstanding voting securities immediately prior to such transaction has beneficial ownership of more than fifty percent of the combined voting power of the surviving entity’s outstanding voting securities immediately after such transaction. Effect of a Change in Control or Certain Other Transactions under the 2012 Option Plan The GRD Holding I Corporation Stock Option Plan, as may be amended from time to time (the “2012 Option Plan”), provides that vested stock options will not be terminated upon the consummation of a merger, consolidation, recapitalization or other similar change in the capital stock of the Company, a liquidation or dissolution of the Company or a Change in Control (as defined in the 2012 Option Plan) (each a “Transaction”) unless holders of affected stock options are provided either (i) a period of at least fifteen calendar days prior to the date of the consummation of the Transaction to exercise the stock options or (ii) payment in respect of each share covered by the option being cancelled in an amount equal to the excess, if any, of the per share price to be paid or distributed to stockholders in the Transaction over the option price of the option. This provision applies to the stock options granted to Messrs. Bird and Corsa. Fiscal Year 2021 Management Bonus Plan Except to the extent specified in the employment agreement of the named executive officers, (i) the obligation of the Company to satisfy payment of a bonus to a named executive officer is conditioned upon the continued employment of such person with the Company at the time determined for payment of the bonus, which timing will be determined by the Compensation Committee or the Board in its sole discretion and generally will be made within two and one half months following the end of the applicable fiscal year and (ii) if the employment of a named executive officer with the Company is terminated for any reason, at any time prior to the time determined for payment of the bonus, the bonus award will be forfeited and automatically be cancelled without further action of the Company. Notwithstanding the foregoing, the Compensation Committee or the Board may in its discretion, provide for the payment of a bonus in the event a named executive officer’s employment with the Company is terminated for any reason including, but not limited to, a termination by the Company without cause or as a result of such person’s death or disability. Such payment may be made on a pro-rated or accelerated basis. AT HOME GROUP INC. 2021 PROXY STATEMENT 59

NAMED EXECUTIVE OFFICER COMPENSATION TABLES Section 401(k) Retirement Savings Plan We maintain a tax-qualified Section 401(k) retirement savings plan that provides for employee contributions and employer “safe harbor” matching contributions equal to 100% of salary deferrals up to 3% of a participant’s compensation and 50% of salary deferrals thereafter up to 5% of a participant’s compensation. Our named executive officers are eligible to participate in this plan on the same basis as other employees who satisfy the plan’s eligibility requirements, including requirements relating to age and length of service. Under this plan, participants may elect to make pre-tax contributions not to exceed the applicable statutory income tax limitation, which, subject to certain exceptions, was $19,500 for calendar year 2020. In addition, certain named executive officers are entitled to an additional catch-up contribution of up to $6,500 for calendar year 2020. Participants are always fully vested in their entire plan account (including with respect to employer contributions). Change of Control/Severance Payment Table The following table estimates the potential payments and benefits to the named executive officers upon termination of employment or a change of control, assuming such event occurs on January 30, 2021. These estimates do not reflect the actual amounts that would be paid to such persons, which would only be known at the time that they become eligible for payment and would only be payable if the specified event occurs. Items Not Reflected in Table The table below does not include (1) accrued salary, accrued bonus and paid time off and (2) amounts outstanding under the Company’s 401(k) plan. Other Notes Applicable to Table • The 2016 Equity Plan provides for the acceleration of vesting of stock option awards under specified circumstances noted above. For purposes of the table, we calculated the intrinsic value of such acceleration, which is the number of stock options accelerated multiplied by the difference between (A) the closing price of our common stock on the NYSE on January 29, 2021, the last trading day of fiscal year 2021 ($24.37) and (B) the exercise price. The value of the acceleration of PSUs and RSUs is calculated as the closing price of our common stock on the NYSE on January 29, 2021, the last trading day of fiscal year 2021 ($24.37), multiplied by the number of unvested shares of our common stock underlying such awards at January 30, 2021. The table does not reflect the intrinsic value of vested stock options, which could be calculated using the information set forth in “Outstanding Equity Awards at January 30, 2021.” The Compensation Committee or Board has discretion to accelerate the vesting of equity awards under the 2016 Equity Plan to the extent not expressly set forth above. The table assumes the Compensation Committee does not utilize such discretion. In addition to the terms of such person’s employment agreement, the Compensation Committee or Board also has discretion to pay bonuses under the fiscal year 2021 management bonus plan as set forth above. The table assumes the Committee does not utilize such discretion. For a termination following a change in control, the table below assumes the change in control event and the termination event occurs as of January 30, 2021. • • • • AT HOME GROUP INC. 2021 PROXY STATEMENT 60

NAMED EXECUTIVE OFFICER COMPENSATION TABLES CEO PAY RATIO As of the end of fiscal year 2021, we employed 7,717 employees, compared to 6,289 employees at the end of fiscal year 2020. The fiscal year 2021 employee count includes 7,026 store employees and 691 other employees across the corporate and distribution center functions. Of the 7,026 store employees, 667 were full-time salaried level staff and the remaining employees consisted of a mix of full-time and part-time hourly workers. For fiscal year 2021, our last completed fiscal year: • Median Employee. The employee identified at the median of all At Home employees (other than our Chief Executive Officer) was a part-time, customer support associate. The total annual compensation of the median employee was $15,556. • Chief Executive Officer. The total annual compensation of our Chief Executive Officer, Mr. Bird, was $8,125,528, as reflected in the Summary Compensation Table. • Ratio. The ratio of the total annual compensation of our Chief Executive Officer to the total annual compensation of our median employee was 522 to 1. The pay ratio increase from fiscal year 2020 was substantially due to the grant of equity awards to Mr. Bird in fiscal year 2021 compared to no equity awards granted to him in fiscal year 2020, as well as Mr. Bird’s earned bonus of 200% of bonus target in fiscal year 2021 compared to no earned bonus in fiscal year 2020. Determination Date The rules pertaining to this pay ratio disclosure permit us to use that same median employee for up to three years. However, we reassessed our median employee for fiscal year 2021 given significant changes to the size and composition of the Company’s employee population throughout fiscal year 2021. Consistent with fiscal year 2020, we determined our median employee as of the last business day of the fiscal year, which was January 29, 2021 for fiscal year 2021. Methodology To identify our median employee, we calculated annual compensation for fiscal year 2021 based on base cash compensation (salary or hourly wages, as applicable) for all full-time, part-time and seasonal employees as of that date. For the majority of our employees, base cash compensation comprises the majority of their compensation. To determine base wages for hourly employees, we used each individual’s pay rate and estimated scheduled hours in the applicable human resources system of record. Compensation for permanent employees hired during the fiscal year was annualized, and we did not apply any cost of living adjustments. Using this compensation measure, we identified a subset of approximately 570 employees representing the potential median employee population. From that subset, we excluded employees who are no longer with the Company and employees who were not employed by the Company for the full fiscal year. To more closely approximate total annual compensation for the remaining subset of employees, we added actual cash bonus to the base cash compensation for such employees and identified the median employee within the group. Once we identified the median employee, we calculated the employee’s total annual compensation for fiscal year 2021 on the same basis as required by the Summary Compensation Table. This pay ratio is a reasonable estimate calculated in a manner consistent with SEC rules based on the methodology described above. The pay ratio reported by other companies may not be comparable to our pay ratio since the SEC rules for identifying the median employee and calculating a pay ratio allow companies to adopt a variety of methodologies, to apply certain exclusions and to make reasonable estimates and assumptions that reflect their employee populations and compensation practices.

PROPOSAL 2—ADVISORY VOTE ON NAMED EXECUTIVE OFFICER COMPENSATION The Board proposes that stockholders provide advisory (non-binding) approval of the compensation of our named executive officers, as disclosed in this Proxy Statement in accordance with the SEC’s rules (commonly known as a “Say-on-Pay” proposal). We recognize the interest our stockholders have in the compensation of our executives and we are providing this advisory proposal in recognition of that interest and as required by Section 14A of the Securities Exchange Act of 1934, as amended (the “Exchange Act”). In a non-binding advisory vote on the frequency of the Say-on-Pay proposal held at our 2019 annual meeting of stockholders, a majority of stockholders voted in favor of holding say-on-pay votes annually. In light of this result and other factors considered by the Board, the Board determined that the Company would hold advisory say-on-pay votes on an annual basis until the next required advisory vote on such frequency, which must be held no later than 2025. SUPPORT FOR RECOMMENDATION As described in detail under the heading “Compensation Discussion and Analysis,” our named executive officer compensation program is designed to attract, motivate and retain our named executive officers, who are critical to our success, and ensure an alignment of interests of such persons with our stockholders. Under this program, our named executive officers are rewarded for their service to the Company, the achievement of specific performance goals and the realization of increased stockholder value. We believe our named executive officer compensation programs also are structured appropriately to support our Company, business objectives and culture. The Compensation Committee and Board regularly review the compensation programs for our named executive officers to ensure the fulfillment of our compensation philosophy and goals. We believe that our stockholders at the 2020 annual meeting recognized our significant stockholder engagement efforts and resulting process for fiscal year 2021 compensation decisions of our named executive officers, the significant compensation changes that were intended prior to the COVID-19 pandemic and the ongoing commitment to align our Chief Executive Officer’s compensation program with that of the other named executive officers. Such collective activities and commitments resulted in a very high level of stockholder support (97.5% approval) for our Say-on-Pay proposal at the 2020 annual meeting. The Board believes that the additional significant changes to compensation programs for our named executive officers in fiscal years 2021 and 2022 fulfill our commitment to implement the changes that the Compensation Committee planned as a result of stockholder feedback. See “Proxy Summary—Executive Compensation Highlights” for detailed information on the Compensation Committee and Board’s responsiveness to our fiscal year 2020 stockholder engagement efforts. See also “Compensation Discussion and Analysis” and “Named Executive Officer Compensation Tables” for additional details about our named executive officer compensation program, including information about the target and earned compensation of our named executive officers in fiscal year 2021. ADVISORY VOTE We are asking our stockholders to indicate their support for our named executive officer compensation as described in this Proxy Statement. This vote is not intended to address any specific item of compensation, but rather the overall compensation of our named executive officers and the philosophy, policies and practices described in this Proxy Statement. Accordingly, we will ask our stockholders to vote “FOR” the following resolution at the Annual Meeting: “RESOLVED, that the Company’s stockholders approve, on an advisory basis, the compensation of the named executive officers, as disclosed in the Company’s Proxy Statement for the 2021 Annual Meeting of Stockholders pursuant to the compensation disclosure rules of the Securities and Exchange Commission, including the Compensation Discussion and Analysis, the Summary Compensation Table and the other related tables and disclosure.” AT HOME GROUP INC. 2021 PROXY STATEMENT 63

PROPOSAL 2—ADVISORY VOTE ON NAMED EXECUTIVE OFFICER COMPENSATION The Say-on-Pay vote is advisory, and therefore not binding on the Company, the Compensation Committee or the Board. We value the opinions of our stockholders and to the extent that this proposal is not approved by a significant margin, the Compensation Committee will evaluate whether any actions are necessary to address the general concerns expressed by this vote. The Board unanimously recommends that the stockholders vote “FOR” Proposal 2 to approve the compensation of our named executive officers, as disclosed in this Proxy Statement pursuant to the rules of the SEC.

CERTAIN RELATIONSHIPS AND RELATED PARTY TRANSACTIONS RELATED PARTY TRANSACTION POLICY The Board has adopted a written Related Party Transaction Policy, providing that the Audit Committee will review and approve or ratify transactions in excess of $120,000 of value in which we participate and in which any of the following persons has or will have a direct or indirect material interest: (i) who is or was at any time since the beginning of our last fiscal year, a director, director nominee or executive officer; (ii) who is the beneficial holder of more than 5% of any class of our voting securities; (iii) any of their immediate family members; or (iv) any entity owned or controlled by any of the foregoing persons. The Audit Committee will approve only those related party transactions that the Audit Committee believes are on their terms, taken as a whole, no less favorable to us than could be obtained in an arm’s-length transaction with an unrelated third party and that the Audit Committee determines are not inconsistent with the best interests of the Company. In particular, the Audit Committee will consider the benefits to the Company, the potential impact on a director’s independence, the availability of other sources for comparable products or services, the terms of the transaction, and the terms available to unrelated third parties or to employees generally. All of the transactions described below were either entered into prior to the adoption of this policy or approved in accordance with this policy. RELATED PARTY TRANSACTIONS The following is a description of related party transactions in existence since the beginning of fiscal year 2021. We believe the terms obtained or consideration that we paid or received, as applicable, in connection with the transactions described below were comparable to terms available or amounts that would be paid or received, as applicable, in arm’s-length transactions with parties unrelated to us and were otherwise in the best interests of the Company. Stockholders’ Agreement In connection with our IPO, the Company and its former sponsors, Starr Investment Holdings, LLC (together with its affiliates, “Starr”) and AEA (collectively with Starr, our “Sponsors”) entered into the Stockholders’ Agreement dated July 22, 2016 (the “Stockholders’ Agreement”). The Stockholders’ Agreement provided for certain rights of our Sponsors to nominate individuals for election to the Board, and required each party to the Stockholders’ Agreement to vote all of its shares to elect such individual to the Board. Affiliates of our Sponsors no longer beneficially own any shares of our common stock and, accordingly, may no longer nominate any individuals for election to the Board. Furthermore, the Stockholders’ Agreement ceased to have effect in fiscal year 2021 when affiliates of our Sponsors ceased to hold any shares of our common stock. Registration Rights Agreement The parties to the Stockholders’ Agreement also entered into a registration rights agreement, dated July 22, 2016, which provided for certain demand and piggyback registration rights. Similar to the Stockholders’ Agreement, the Registration Rights Agreement ceased to have effect in fiscal year 2021 when affiliates of our Sponsors ceased to hold any shares of our common stock. 360 Holdings Royalty Agreement and Inventory Purchases 360 Holdings III Corp.

PROPOSAL 3—RATIFICATION OF THE APPOINTMENT OF THE INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM The Audit Committee of the Board has appointed Ernst & Young as our independent registered public accounting firm for the fiscal year ending January 29, 2022. Ernst & Young has served as our independent registered accounting firm since 2013. The services provided to us by Ernst & Young in fiscal years 2021 and 2020 are described below under the heading “Audit Committee Matters—Ernst & Young’s Fees and Services.” We expect that representatives of Ernst & Young will be present at the Annual Meeting to respond to appropriate questions and to make a statement if they so desire. SUPPORT FOR RECOMMENDATION In determining that retaining Ernst & Young for 2021 was in the best interests of the Company and its stockholders, our Audit Committee reviewed, among other things: • Audit effectiveness. Ernst & Young’s performance on the Company’s audit and non-audit work for fiscal year 2021 and recent prior years, and management’s assessment of such performance. Expertise and industry knowledge. Ernst & Young’s qualifications, independence, capabilities and expertise, evident through its audit planning and reports, industry knowledge, resources and staffing, objectivity and professional skepticism. External data on audit quality and performance. Results of recent PCAOB reports on Ernst & Young and peer firms and improvements made from period to period. Reasonableness of fees. The terms of the audit engagement, including the reasonableness of audit and non-audit fees charged taking into account the breadth and complexity of services provided, as well as the efficiency achieved in performing such services. Communication. The quality of Ernst & Young’s communications to and interactions with our Audit Committee at meetings and our Audit Committee Chair between meetings. Auditor Tenure. The benefits of having a long-tenured auditor and the institutional knowledge gained from prior years of engagement. • • • • • Further, in accordance with SEC rules, the maximum number of consecutive years of service for lead and concurring review audit partners for public companies is five years. Our lead audit partner has served in such role since fiscal year 2019 and therefore has two years of service remaining in such capacity. Assuming the continuing engagement of Ernst & Young as our independent registered public accounting firm, our Audit Committee will pursue a process in considering potential lead auditor candidates and will obtain significant input from management and Ernst & Young, conduct interviews and take other appropriate actions before it approves the new lead engagement partner.

PROPOSAL 3—RATIFICATION OF THE APPOINTMENT OF THE INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM ADVISORY VOTE The Audit Committee is responsible for selecting the Company’s independent registered public accounting firm for the fiscal year ending January 29, 2022. Accordingly, stockholder approval is not required to appoint Ernst & Young as our independent registered public accounting firm. However, the Audit Committee will take the outcome of the vote on this proposal into consideration when appointing our independent registered public accounting firm in the future. The Audit Committee may retain another independent registered public accounting firm at any time during the year if it concludes that such change would be in the best interest of the Company’s stockholders, even if the stockholders approve this proposal. The Board unanimously recommends that the stockholders vote “FOR” Proposal 3 to ratify the appointment of Ernst & Young LLP as the independent registered public accounting firm of At Home Group Inc. for the fiscal year ending January 29, 2022.

AUDIT COMMITTEE MATTERS PRE-APPROVAL POLICIES AND PROCEDURES The Audit Committee has adopted a policy requiring that substantially all audit, audit-related and non-audit services provided by the independent registered public accounting firm be pre-approved by the Audit Committee and identifying certain prohibited non-audit services. Pre-approval is not necessary for certain minor non-audit services that: (i) do not constitute more than 5% of the total amount of revenues paid by the Company to Ernst & Young during the fiscal year the non-audit services were provided; (ii) were not recognized by the Company to be non-audit services at the time of the engagement for such services; and (iii) such services are promptly brought to the attention of the Audit Committee and approved, prior to the completion of the audit, by the Audit Committee or by one or more members of the Audit Committee whom authority to grant such approvals has been delegated by the Audit Committee. The Audit Committee may delegate authority to one or more independent members of the Audit Committee to grant pre-approvals of audit and permitted non-audit services, provided that any such pre-approvals are reported to the full Audit Committee at its next scheduled meeting. During fiscal year 2021, all of the non-audit services provided to us by Ernst & Young were pre-approved by the Audit Committee. The Audit Committee’s pre-approval policy is in the Audit Committee Charter, which is available on our website at investor.athome.com. ERNST & YOUNG’S FEES AND SERVICES The following is a description of the professional services performed and the fees billed by Ernst & Young for fiscal year 2021 and 2020. All of such services were approved in conformity with the pre-approval policies and procedures described above. The Audit Committee has considered whether the services provided by Ernst & Young were compatible with maintaining Ernst & Young’s independence and, based on its reviews and discussions with management and Ernst & Young noted above, has determined that the nature and substance of the services did not impair the status of Ernst & Young as the Company’s independent registered public accounting firm.

REPORT OF THE AUDIT COMMITTEE The Audit Committee oversees, among other things, the Company’s financial reporting and internal control processes on behalf of the Board, the qualifications, scope of work, performance and independence of Ernst & Young, the operation of a system of internal controls designed to ensure the integrity of the Company’s financial statements and reports and compliance with laws, regulations and corporate policies. Management has the primary responsibility for the preparation, presentation and integrity of the Company’s financial statements, accounting and financial reporting principles, internal controls and compliance with applicable laws and regulations. Ernst & Young, the Company’s independent registered public accounting firm, is responsible for performing an independent audit of the Company’s consolidated financial statements and the effectiveness of the Company’s internal control over financial reporting in accordance with the standards of the Public Company Accounting Oversight Board (U.S.) (“PCAOB”) and for expressing its opinions thereon. KEY RESPONSIBILITIES The responsibilities of the Audit Committee include engaging an accounting firm to be the Company’s independent registered public accounting firm, establishing the terms of retention, including compensation, and overseeing its work. Meeting agendas are established by the Chair of the Audit Committee, together with members of management. In fiscal year 2021, among other things, the Audit Committee: • Reviewed and discussed with management and Ernst & Young the unaudited quarterly financial statements included in each Quarterly Report on Form 10-Q filed with the SEC. Periodically reviewed and discussed with management and Ernst & Young the Company’s earnings press releases, earnings guidance and the use of non-GAAP information. Received updates on management’s process to assess the adequacy of the Company’s system of internal control over financial reporting, the framework used to make the assessment and management’s conclusions on the effectiveness thereof. Discussed with Ernst & Young, the Company’s internal control assessment process, management’s assessment with respect thereto and Ernst & Young’s evaluation of the Company’s system of internal control over financial reporting. Considered the Company’s critical accounting policies and procedures and significant judgments and estimates, and changes in the Company’s accounting practices, principles, controls or methodologies or in its financial statements. Reviewed the appropriateness of the services and fees of Ernst & Young and pre-approved, in accordance with its charter, audit services and permissible non-audit services to be provided to the Company by Ernst & Young. Reviewed the integrity and adequacy of the Company’s auditing, accounting and financial reporting processes, the Company’s internal scope of work and audit plan and the performance of the internal audit function. Reviewed with management and Ernst & Young significant risks and exposures identified by management and the overall adequacy and effectiveness of the Company’s legal, regulatory and ethical compliance programs. • • • • • • • AT HOME GROUP INC. 2021 PROXY STATEMENT 71

REPORT OF THE AUDIT COMMITTEE REQUIRED COMMUNICATIONS Furthermore, as part of its oversight of the Company’s annual report on Form 10-K for fiscal year 2021, the Audit Committee reviewed and discussed, with management and Ernst & Young, the Company’s audited consolidated financial statements and related footnotes for the fiscal year ended January 30, 2021 and Ernst & Young’s report on those financial statements. The Audit Committee has discussed with Ernst & Young the matters required to be discussed by the applicable requirements of the PCAOB and the SEC. These required communications included Ernst & Young’s perspective on the quality (not merely the acceptability) of the Company’s accounting principles, the reasonableness of significant estimates and judgments made by management, and the disclosures in the audited consolidated financial statements, including the disclosures relating to critical accounting policies. The Audit Committee also received the written disclosures and letter from Ernst & Young required by the applicable requirements of the PCAOB regarding Ernst & Young’s communications with the Audit Committee concerning independence. The Audit Committee has discussed with Ernst & Young its independence with respect to the Company and has considered whether Ernst & Young’s provision of non-audit services is compatible with its independence. RECOMMENDATION OF AUDIT COMMITTEE Based upon these reviews and discussions, the Audit Committee recommended to the Board that the Company’s audited consolidated financial statements be included in the annual report on Form 10-K for the fiscal year ended January 30, 2021 to be filed with the SEC. The Audit Committee also appointed Ernst & Young to serve as the Company’s independent registered public accounting firm for the fiscal year ending January 29, 2022.

PROPOSAL 4—AMENDMENT TO THE AMENDED AND RESTATED AT HOME GROUP INC. EQUITY INCENTIVE PLAN We are asking our stockholders to approve a second amendment (the “Amendment”) to the 2016 Equity Plan, which will not become effective unless and until stockholder approval is obtained. The Amendment would: We expect that the total Shares available for future Awards under the 2012 Option Plan and the 2016 Equity Plan, as amended by the Amendment, would be sufficient to cover expected equity grants for approximately four years based on current forecasts and estimates to future grants of equity awards, expected expirations, terminations and forfeitures and assuming maximum performance of future PSUs and that our share price remains at then-current levels or higher. See “Proxy Summary—Overview of the Equity Plan Proposal” for a table setting forth information regarding the outstanding equity awards, and the number of shares remaining for grant, as of April 19, 2021. Further, the 3,250,000 shares of common stock represent approximately 5% of our outstanding shares of common stock as of April 19, 2021. Potential stockholder dilution (equal to the number of Shares subject to our outstanding Awards, plus the number of shares available to be granted, divided by total shares of common stock outstanding), including the additional requested Shares, would be approximately 20% as of April 19, 2021. No discounted stock options No repricing or exchange of underwater options without stockholder approval No automatic annual share replenishment or shares grants No liberal share recycling Minimum one-year vesting for all new awards under amended plan, with customary exception for 5% of new awards No dividend payments for any unvested awards for new awards under amended plan No tax gross-ups on change in control vesting AT HOME GROUP INC. 2021 PROXY STATEMENT 73 Our Clawback Policy Applies to Equity Awards Our clawback policy empowers the Board to seek recovery of any cash or equity-based incentive compensation paid to executive officers in specified circumstances to the fullest extent permitted by governing law. 2016 Equity Plan Features (As Amended) We Thoughtfully Manage our Burn Rate Our independent Compensation Committee, with advice from its compensation consultant, Pearl Meyer, regularly reviews our historical share usage and availability and considers such information in setting equity compensation levels. Recognizing that equity awards dilute stockholder equity and must be used appropriately, our Compensation Committee administers and oversees our equity compensation practices to ensure they are reasonable. We believe our historical share usage effectively balances the needs of our employees with stockholder interests. • Increase by 3,250,000 the maximum number of shares of our common stock (the “Shares”) that may be issued pursuant to awards granted under the 2016 Equity Plan • Impose a one-year minimum vesting requirement for substantially all new awards granted under the 2016 Equity Plan • Prohibit the payment of dividends on any unvested awards newly granted under the 2016 Equity Plan

PROPOSAL 4—AMENDMENT TO THE AMENDED AND RESTATED AT HOME GROUP INC. EQUITY INCENTIVE PLAN Burn Rate(1) 5.17% 2.40% 4.38% 3.98% (1) Defined as the number of shares subject to equity awards granted in a fiscal year divided by the weighted average shares outstanding for that fiscal year. This amount does not take into account any cancellations or forfeitures. Currently, subject to any adjustment as provided in the 2016 Equity Plan, (i) up to 2,478,702 Shares (the “IPO Bonus Pool”) were issuable pursuant to Awards granted under the 2016 Equity Plan to senior executives of the Company in connection with our IPO and (ii) up to 7,218,053 Shares may be issued pursuant to Awards granted under the 2016 Equity Plan (other than the IPO Bonus Pool) (the “Post-IPO Share Pool”), all of which may be granted pursuant to incentive stock options (“ISOs”). Under the 2016 Equity Plan, awards may be granted in the form of stock options, restricted stock, RSUs, stock appreciation rights, dividend equivalent rights, performance-based awards (including performance units, PSUs and performance-based restricted stock) and Shares, as described further below. As of April 19, 2021, there remained 1,115,122 Shares available for grant under the 2016 Equity Plan. As of April 19, 2021, there were also 29,333 shares available for future grant under the 2012 Option Plan, and no Shares available for grant under any other Company equity incentive plan. The following is a summary of the material features of our 2016 Equity Plan, as amended by the proposed Amendment, and does not describe all of the 2016 Equity Plan’s provisions. We urge you to read the complete text of the Amendment and the 2016 Equity Plan. The proposed Amendment is set forth on Appendix A to this Proxy Statement. The full text of the 2016 Equity Plan (not reflecting the proposed Amendment) is set forth on Appendix B to this Proxy Statement. If our stockholders approve the Amendment, a registration statement on Form S-8 covering the Shares newly available for issuance will be filed with the SEC. PROPOSED AMENDMENT Increase Share Limit The Amendment would increase by 3,250,000 the number of Shares authorized under the 2016 Equity Plan, which would provide for the issuance of up to an aggregate of 10,468,053 Shares pursuant to grants made or to be made under the Post-IPO Share Pool of the 2016 Equity Plan, subject to the adjustment described under “Adjustments upon Changes in Capitalization” below. The market value of the additional 3,250,000 Shares authorized to be granted pursuant to Awards under the 2016 Equity Plan is $94,152,500 based on the closing price of a Share on April 19, 2021 ($28.97). Based on the Compensation Committee’s expectation to continue utilization of annual grants under a long-term equity incentive program and other projected grant needs, the Company will not have adequate ability to grant equity awards to accommodate the Company’s expected needs over the next several years without stockholder approval of this Amendment. In determining the appropriate size of the available Shares under the 2016 Equity Plan, the Compensation Committee considered the Company’s historical and projected Share usage, taking into account estimated expirations, terminations and forfeitures, estimated payouts for the outstanding PSUs, the nature and type of Awards granted by the Company historically and potentially in the future, including potential payout multipliers, and the Compensation Committee’s belief that long-term equity incentive compensation is a necessary component of the Company’s compensation program for key employees. The Compensation Committee also received advice from its compensation consultant, Pearl Meyer, and reviewed third-party data and voting policies. Our 2016 Equity Plan has no evergreen, or automatic share reload, feature. If stockholders do not approve the Amendment, the 2016 Equity Plan will remain in effect in accordance with its pre-existing terms and with the pre-existing number of Shares authorized for issuance under the 2016 Equity Plan. Require Minimum Vesting Period If the Amendment is adopted, Awards made after such Amendment under the 2016 Equity Plan would be subject to a minimum one-year vesting requirement, with a customary exception for 5% of new awards (the “Minimum Vesting AT HOME GROUP INC. 2021 PROXY STATEMENT 74 Historical Dilution and Burn Rate Percentages: Three-Fiscal Year Fiscal Year 2019 Fiscal Year 2020 Fiscal Year 2021 Average

PROPOSAL 4—AMENDMENT TO THE AMENDED AND RESTATED AT HOME GROUP INC. EQUITY INCENTIVE PLAN Requirement”). The Minimum Vesting Requirement would not preclude or limit any Award (or any action by the Committee) from providing for accelerated vesting of such Award in connection with a Change in Control. The Board believes that the adoption of the Minimum Vesting Requirement promotes effective corporate governance and strong compensation practices. Prohibit Payment of Dividends on Unvested Awards Consistent with our current Award practices, the Amendment also would prohibit the payment of dividends with respect to Shares subject to any Award (including any Dividend Equivalent Right) made after such Amendment until and to the extent the Shares vest in accordance with their terms. The Board believes that such prohibition aligns Awards with the purpose of performance and vesting conditions of the Awards, and desires to formalize its current practice in the 2016 Equity Plan. REASONS TO VOTE FOR THE AMENDMENT Importance of Equity Awards to Our Compensation Programs We believe that the additional Shares requested to be approved by stockholders are: • A critical tool for attracting, retaining motivating and incentivizing qualified employee talent to drive the long-tern success of our business. As discussed under “Compensation Discussion and Analysis,” our compensation program for our named executive officers is designed to attract and retain high performing executive leaders who drive our long-term success and increase stockholder value. We believe that our prudent use of equity compensation has been an important factor in driving our strong growth historically and is a vital element of our future success. We compete for strong talent and equity-based compensation is a key component of being able to attract top-tier talent who can help drive our operations and growth. Approval of the Amendment is necessary in order for us to continue our practice of granting equity-based compensation to key employees throughout the organization. A key component to further align participants with the interests of our long-term stockholders. We use Awards to further align executives’ and employees’ long-term interests with those of our stockholders, incentivize executives and employees to increase long-term stockholder value, ensure alignment with strategic priorities and overall long-term profitability and ensure that our compensation program pays for performance. Our Award mix of stock options, RSUs and PSUs ensure our key employees are motivated to take, and rewarded from taking, actions in the long-term best interests of the Company, which results in stock price appreciation over time. Further, our increasing pay-for-performance focus with PSUs directly incentivize the achievement of key performance metrics that drive long-term financial performance and stockholder value. Similarly, we utilize Awards to further align our non-employee directors with the long-term interests of our stockholders, and to incentivize such persons to join and contribute significantly to our Board. • As of April 19, 2021, approximately 496 of our current or former officers, employees, consultants and non-employee directors held outstanding equity awards. Currently Available Shares under the 2016 Equity Plan Are Insufficient for Our Forecasted Needs As of April 19, 2021, after giving effect to expirations, terminations, settlements in cash and forfeitures to date, there remained 1,115,122 Shares available for grant under the 2016 Equity Plan. We beleive additional Shares must be reserved for issuance under the 2016 Equity Plan to meet our estimated equity compensation needs. We expect that the Shares available for future Awards under the 2012 Option Plan and 2016 Equity Plan, as amended by the Amendment, would be sufficient to cover expected equity grants for approximately four years based on our current forecasts and estimates related to future grants of equity awards, as well as an estimated amount of expirations, terminations, and forfeitures (including maximum performance on PSUs), and assuming our share price remains at then-current levels or higher. A reduction in our use of equity-based compensation will require additional cash compensation, which could adversely impact our liquidity and capital resources, and could limit the cash we have to invest in operating activities that will drive our growth model. AT HOME GROUP INC. 2021 PROXY STATEMENT 75

PROPOSAL 4—AMENDMENT TO THE AMENDED AND RESTATED AT HOME GROUP INC. EQUITY INCENTIVE PLAN We Thoughtfully Manage our Burn Rate and Dilution Rate Our Compensation Committee, with advice from its compensation consultant Pearl Meyer, periodically reviews our historical Share usage and availability and considers such information in making Awards each year and in strategically designing its long-term equity incentive program. Our Compensation Committee administers and oversees our equity compensation practices to ensure they are reasonable, recognizing that equity awards dilute stockholder equity and must be used reasonably and effectively, and we believe our historical share usage has achieved such objectives. Our three-year average burn rate was 3.98% respectively, for fiscal years 2019 through 2021. The Amendment Implements Additional Strong Governance Practices The Compensation Committee, with advice from its advisors, periodically reviews and discusses market trends and practices regarding incentive-based compensation, including long-term equity incentive programs. The Amendment ‘s proposed provisions reflect additional strong governance practices among leading peers and best-practice public companies for equity plans and is in the best interests of the Company and our stockholders. SUMMARY OF 2016 EQUITY PLAN (AS AMENDED BY THE AMENDMENT) Administration A committee appointed by the Board (the “Committee”) administers the 2016 Equity Plan. The Committee must consist of at least two members of the Board, and may consist of the entire Board. The Committee will generally consist of at least two directors considered to be non-employee directors for purposes of Section 16 of the Exchange Act, and to the extent that an award is intended to qualify as “performance-based compensation” within the meaning of Section 162(m) of the Code, the Committee will consist of at least two members of the Board, each of whom qualifies as an “outside director,” as defined in Section 162(m) of the Code. As discussed more fully above under the heading “Tax and Accounting Implications—Deductability of Executive Compensation”, Section 162(m) of the Code was amended by the Tax Act to eliminate an exception from the compensation deduction limitations for compensation that was considered “qualified performance-based compensation” under the applicable regulations. Prohibition on Repricings The Committee has no authority to make any adjustment or amendment (other than in connection with certain changes in capitalization or certain corporate transactions in accordance with the terms of the 2016 Equity Plan, as generally described below) that reduces, or would have the effect of reducing, the exercise price of an Option or SAR previously granted under the 2016 Equity Plan, unless the Company’s stockholders approve such adjustment or amendment. Plan Term The 2016 Equity Plan became effective on September 11, 2015, the date it was approved by the Board, subject to the approval of our existing stockholders, and will terminate on September 11, 2025, the tenth anniversary of the effective date, unless earlier terminated by the Board. Eligibility Under the 2016 Equity Plan, “Eligible Individuals” include employees, consultants and directors providing services to the Company and its subsidiaries and affiliates. The Committee will determine which Eligible Individuals will receive grants of awards. As of April 19, 2021, the Company has approximately 7,479 employees (including nine executive officers) and nine non-employee directors (which will be reduced to eight as of the Annual Meeting). We have not historically granted equity to consultants, so we are unable to reasonably estimate the number of consultants, if any, who may be eligible to receive awards under the 2016 Equity Plan. AT HOME GROUP INC. 2021 PROXY STATEMENT 76

PROPOSAL 4—AMENDMENT TO THE AMENDED AND RESTATED AT HOME GROUP INC. EQUITY INCENTIVE PLAN Incentives Available Under the 2016 Equity Plan, the Committee may grant any of the following types of awards to an Eligible Individual: ISOs and nonqualified stock options (“Nonqualified Stock Options,” and together with ISOs, “Options”); stock appreciation rights (“SARs”); restricted stock (“Restricted Stock”); RSUs; performance awards (“Performance Awards”); dividend equivalent rights (“Dividend Equivalent Rights”); and Share Awards, as defined below (each type of grant is considered an “Award”). Individual Award Limits With respect to Awards granted following the last day of the Transition Period (as defined in the 2016 Equity Plan), (a) the aggregate number of shares that may be the subject of Option or SARs granted in any calendar year (or in respect of the calendar year during which the Transition Period expires, the remainder of such calendar year) may not exceed 3,000,000 Shares in the case of an Eligible Individual who is not a non-employee director, or 90,000 Shares in the case of a non-employee director, (b) the aggregate number of Shares that may be the subject of Performance-Based Restricted Stock and PSUs granted in any calendar year (or in respect of the calendar year during which the Transition Period expires, the remainder of such calendar year) may not exceed 1,000,000 Shares in the case of an Eligible Individual who is not a non-employee director, or 30,000 Shares in the case of a non-employee director, and (c) the maximum dollar amount of cash or the fair market value of Shares that any Eligible Individual may receive in any calendar year (or in respect of the calendar year during which the Transition Period expires, the remainder of such calendar year) in respect of Performance Units may not exceed $10,000,000. If an Award or any portion thereof that is issued from the Post-IPO Share Pool (i) expires or otherwise terminates without all of the Shares covered by such Award having been issued or (ii) is settled in cash (i.e., the participant receives cash rather than Shares), such expiration, termination or settlement will not reduce (or otherwise offset) the number of Shares that may be available for issuance under the 2016 Equity Plan. Any Shares issued pursuant to an Award that are forfeited and returned back to or reacquired by the Company will again become available for issuance under the 2016 Equity Plan. Any Shares tendered or withheld to pay the exercise price of an Option or the base price of an SAR, or to satisfy tax withholding obligations associated with any Award, may not become available again for issuance under the 2016 Equity Plan. Under no circumstances will Shares underlying any Awards issued under the IPO Bonus Pool, once issued, again become available for issuance under the 2016 Equity Plan. Minimum Vesting Requirement Notwithstanding any other provisions of the Plan, Awards made under the 2016 Equity Plan subject to the Amendment may vest no earlier than one year from the date of grant of such Award. However, Awards with respect to up to 5% in the aggregate of the total Shares authorized for issuance under the 2016 Equity Plan for new Awards (as of the effectiveness of the Amendment and thereafter, including any additional shares approved by stockholders thereafter through the termination of the 2016 Equity Plan), may be granted without respect to the Minimum Vesting Requirement. The Minimum Vesting Requirement will not preclude or limit any Award or other arrangement (or any action by the Committee) from providing for accelerated vesting of such Award in connection with a Change in Control. No Dividend Equivalent Rights or Dividends Payable for Unvested Awards Notwithstanding any other provisions of the Plan, Awards made under the 2016 Equity Plan subject to the Amendment will not provide for any payment on any Award (including Dividend Equivalent Rights) or portion of any Award (including Dividend Equivalent Rights) that is not vested, and all distributions, if any received by a participant for Restricted Stock or performance-based Restricted Stock as a result of any share split, share dividend, combination of shares or other similar transaction will be subject to the restrictions applicable to the original Award. Options The Committee may grant Options (which may be ISOs or Nonqualified Stock Options) to Eligible Individuals. An ISO is an Option intended to qualify for tax treatment applicable to ISOs under Section 422 of the Code. An ISO may be granted only to Eligible Individuals that are employees of the Company or any of its subsidiaries. A Nonqualified Stock Option is an Option that is not intended to be an ISO.

PROPOSAL 4—AMENDMENT TO THE AMENDED AND RESTATED AT HOME GROUP INC. EQUITY INCENTIVE PLAN Vesting and Exercise Periods Each Option granted under the 2016 Equity Plan may be subject to certain vesting requirements and will become exercisable in accordance with the specific terms and conditions of the Option, as determined by the Committee at the time of grant and set forth in an Award agreement. The term of an Option generally may not exceed ten years from the date it is granted (five years in the case of an ISO granted to a ten-percent stockholder). Each Option, to the extent it becomes exercisable, may be exercised at any time in whole or in part until its expiration or termination, unless otherwise provided in applicable Award agreement. Exercise Price The purchase price per Share with respect to any Option granted under the 2016 Equity Plan may be not less than 100% of the fair market value of a share of Common Stock on the date the Option is granted (110% in the case of an ISO granted to a ten-percent stockholder). Limits on ISOs In order to comply with the requirements for ISOs in the Code, no person may receive a grant of an ISO for stock that would have an aggregate fair market value in excess of $100,000, determined when the ISO is granted, that would be exercisable for the first time during any calendar year. If any grant of an ISO is made in excess of such limit, the portion that is over the $100,000 limit would be a Nonqualified Stock Option. Stock Appreciation Rights The Committee may grant SARs to Eligible Individuals on terms and conditions determined by the Committee at the time of grant and set forth in an Award agreement. An SAR may be granted (a) at any time if unrelated to an Option or (b) if related to an Option, either at the time of grant or at any time thereafter during the term of the Option. An SAR is a right granted to a participant to receive an amount equal to the excess of the fair market value of a Share on the last business day preceding the date of exercise of such SAR over the fair market value of a Share on the date the SAR was granted. Each SAR will be exercisable or be forfeited or expire on such terms as the Committee determines. Except in limited circumstances, an SAR has a maximum term of ten years. An SAR may be settled or paid in cash, Shares or a combination of each, in accordance with its terms. Dividend Equivalent Rights Subject to the prohibition for the payment of dividends on unvested Awards under the Amendment, the Committee may grant Dividend Equivalent Rights, either in tandem with an Award or as a separate Award, to Eligible Individuals on terms and conditions determined by the Committee at the time of grant and set forth in an Award agreement. A Dividend Equivalent Right is a right to receive cash or Shares based on the value of dividends that are paid with respect to the Shares. Dividend Equivalent Rights may be settled in cash or shares of Common Stock or a combination thereof, in a single installment or multiple installments, as determined by the Committee. Restricted Stock; RSUs The Committee may grant either Shares (Restricted Stock) or phantom Shares (RSUs), in each case subject to certain vesting requirements, on terms and conditions determined by the Committee at the time of grant and set forth in an Award agreement. Restricted Stock Unless the Committee determines otherwise, upon the issuance of shares of Restricted Stock, the participant has all of the rights of a stockholder with respect to such Shares, including the right to vote the Shares and to receive all dividends or other AT HOME GROUP INC. 2021 PROXY STATEMENT 78

PROPOSAL 4—AMENDMENT TO THE AMENDED AND RESTATED AT HOME GROUP INC. EQUITY INCENTIVE PLAN distributions made with respect to the Shares (subject to the prohibition for the payment of dividends on unvested Awards under the Amendment); provided, that all distributions, if any, received by a participant with respect to Restricted Stock as a result of any share split, share dividend, combination of shares, or other similar transaction shall be subject to the restrictions applicable to the original Award. Payment of deferred dividends in respect of shares of Restricted Stock will be made upon the lapsing of restrictions imposed on the shares of Restricted Stock in respect of which the deferred dividends were paid, and any dividends deferred in respect of any shares of Restricted Stock will be forfeited upon the forfeiture of such shares of Restricted Stock. RSUs Each RSU represents the right of the participant to receive a payment upon vesting of the RSU, or on any later date specified by the Committee, of an amount equal to the fair market value of a Share as of the date the RSU becomes vested, or such later date as determined by the Committee at the time the RSU is granted (and which will be set forth in the applicable Award agreement). An RSU may be settled or paid in cash, Shares or a combination of each, as determined by the Committee. Performance Awards Performance Awards, which include performance units (“Performance Units”), PSUs and performance-based restricted stock (“Performance-Based Restricted Stock”), may be granted to Eligible Individuals on terms and conditions determined by the Committee and set forth in an Award agreement. Performance Units and PSUs Performance Units are denominated in a specified dollar amount and, contingent upon the attainment of specified performance objectives within a performance period and such other vesting conditions as may be determined by the Committee (including without limitation, a continued employment requirement following the end of the applicable performance cycle), represent the right to receive payment of the specified dollar amount or a percentage of the specified dollar amount depending on the level of performance objective attained; provided, however, that the Committee may at the time a Performance Unit is granted specify a maximum amount payable in respect of a vested Performance Unit. PSUs are denominated in Shares and, contingent upon the attainment of specified performance objectives within a performance period and such other vesting conditions as may be determined by the Committee (including without limitation, a continued employment requirement following the end of the applicable performance cycle), represent the right to receive payment of the fair market value of a Share on the date the PSU was granted, the date the PSU became vested or any other date specified by the Committee or a percentage of such amount depending on the level of performance objective attained; provided, however, that the Committee may at the time a PSU is granted specify a maximum amount payable in respect of a vested PSU. The Award agreement for each Performance Unit and PSU shall specify (i) the number of Performance Units or PSUs to which the agreement relates, (ii) the performance objectives and other conditions which must be satisfied in order for the Performance Unit or PSU to vest, (iii) the performance period within which the performance objectives must be satisfied and (iv) the circumstances under which the Award will be forfeited. Performance-Based Restricted Stock Performance-Based Restricted Stock consists of an Award of shares of Restricted Stock issued in the participant’s name and subject to appropriate restrictions and transfer limitations. Unless the Committee determines otherwise and as set forth in the applicable Award agreement, upon issuance of Shares of Performance-Based Restricted Stock, the participant has all of the rights of a stockholder with respect to such Shares, including the right to vote the Shares and to receive all dividends or other distributions paid or made with respect to Shares (subject to the prohibition for the payment of dividends on unvested Awards under the Amendment); provided, that all distributions, if any, received by a participant with respect to Performance-Based Restricted Stock as a result of any share split, share dividend, combination of shares, or other similar transaction shall AT HOME GROUP INC. 2021 PROXY STATEMENT 79

PROPOSAL 4—AMENDMENT TO THE AMENDED AND RESTATED AT HOME GROUP INC. EQUITY INCENTIVE PLAN be subject to the restrictions applicable to the original Award. Payment of deferred dividends in respect of Shares of Performance-Based Restricted Stock will be made upon the lapsing of restrictions imposed on the Performance-Based Restricted Stock in respect of which the deferred dividends were paid, and any dividends deferred in respect of any Performance-Based Restricted Stock will be forfeited upon the forfeiture of such Performance-Based Restricted Stock. The Award agreement for each Award of Performance-Based Restricted Stock will specify (i) the number of shares of Performance-Based Restricted Stock to which the agreement relates, (ii) the performance objectives and other conditions that must be satisfied in order for the Performance-Based Restricted Stock to vest, (iii) the performance period within which the performance objectives must be satisfied (which will not be less than one year) and (iv) the circumstances under which the Award will be forfeited. Performance Objectives As discussed more fully above under the heading “Tax and Accounting Implications—Deductability of Executive Compensation”, Section 162(m) of the Code was amended by the Tax Act to eliminate an exception from the compensation deduction limitations for compensation that was considered “qualified performance-based compensation” under the applicable regulations. With respect to any Performance Awards granted prior to the effectiveness of the Tax Act amendment and intended to constitute “performance-based compensation” under Section 162(m) of the Code, performance objectives (“Performance Objectives”) could be expressed in terms of (i) earnings per share; (ii) operating income; (iii) return on equity or assets; (iv) cash flow; (v) net cash flow; (vi) cash flow from operations; (vii) EBITDA and/or adjusted EBITDA; (viii) revenue growth, product revenue and/or comparable sales growth; (ix) revenue ratios; (x) cost reductions; (xi) cost ratios or margins; (xii) overall revenue or sales growth; (xiii) expense reduction or management; (xiv) market position or market share; (xv) total stockholder return; (xvi) return on investment; (xvii) earnings before interest and taxes (EBIT); (xviii) net income (before or after taxes); (xix) return on assets or net assets; (xx) economic value added; (xxi) stockholder value added; (xxii) cash flow return on investment; (xxiii) net operating profit; (xxiv) net operating profit after tax; (xxv) return on capital; (xxvi) return on invested capital; (xxvii) customer growth; (xxviii) supply chain achievements; (xxix) financial ratios, including those measuring liquidity, activity, profitability or leverage; (xxx) financing and other capital raising transactions; (xxxi) strategic partnerships or transactions; or (xxxii) any combination of the foregoing. Performance Objectives could be in respect of the performance of the Company, any of its subsidiaries or Divisions (as defined in the 2016 Equity Plan) or any combination thereof. Performance Objectives could be absolute or relative (to prior performance of the Company or to the performance of one or more other entities or external indices) and could be expressed in terms of a progression within a specified range. The Committee could, at the time the Performance Objectives in respect of a Performance Award are established, provide for the manner in which performance will be measured against the Performance Objectives to reflect the impact of specified events, including any one or more of the following with respect to the applicable performance period: (i) the gain, loss, income or expense resulting from changes in accounting principles or tax laws that become effective during the performance period; (ii) the gain, loss, income or expense reported publicly by the Company with respect to the performance period that are extraordinary or unusual in nature or infrequent in occurrence; (iii) the gains or losses resulting from, and the direct expenses incurred in connection with, the disposition of a business or the sale of investments or non-core assets; (iv) the gain or loss from all or certain claims and/or litigation and all or certain insurance recoveries relating to claims or litigation; or (v) the impact of investments or acquisitions made during the year or, to the extent provided by the Committee, any prior year. The events could relate to the Company as a whole or to any part of the Company’s business or operations, as determined by the Committee at the time the Performance Objectives were established. Any adjustments based on the effect of certain events are to be determined in accordance with generally accepted accounting principles and standards, unless another objective method of measurement is designated by the Committee. Prior to the vesting, payment, settlement or lapsing of any restrictions with respect to any Performance Award granted prior to the effectiveness of the Tax Act amendment and intended to qualify as “performance-based compensation” under Section 162(m) of the Code, the Committee must certify in writing that the applicable Performance Objectives have been satisfied. In respect of a Performance Award, the Committee may, in its sole discretion, (i) reduce the amount of cash paid or number of Shares to be issued or that have been issued and that become vested or on which restrictions lapse and/or (ii) establish rules and procedures that have the effect of limiting the amount payable to any participant to an amount that is AT HOME GROUP INC. 2021 PROXY STATEMENT 80

PROPOSAL 4—AMENDMENT TO THE AMENDED AND RESTATED AT HOME GROUP INC. EQUITY INCENTIVE PLAN less than the amount that otherwise would be payable under such Award. The Committee may exercise such discretion in a non-uniform manner among participants. Share Awards The Committee may grant an Award of Shares (“Share Awards”) to an Eligible Individual on such terms and conditions as the Committee may determine at the time of grant. A Share Award may be made as additional compensation for services rendered by the Eligible Individual or may be in lieu of cash or other compensation to which the Eligible Individual is entitled from the Company. Adjustments upon Changes in Capitalization In the event that the outstanding Shares are changed into or exchanged for a different number or kind of Shares or other stock or securities or other equity interests of the Company or another corporation or entity, whether through merger, consolidation, reorganizations, recapitalization, reclassification, stock dividend, stock split, reverse stock split, substitution or other similar corporate event or transaction or an extraordinary dividend or distribution by the Company in respect of its Shares or other capital stock or securities convertible into capital stock in cash, securities or other property, the Committee will determine the appropriate adjustments, if any, to (a) the maximum number and kind of shares of stock or other securities or other equity interests as to which Awards may be granted under the 2016 Equity Plan, (b) the maximum number and class of Shares or other stock or securities that may be issued upon exercise of ISOs, (c) the number and kind of Shares or other securities covered by any or all outstanding Awards that have been granted under the 2016 Equity Plan, (d) the option price of outstanding Options and the base price of outstanding SARs and (e) the Performance Objectives applicable to outstanding Performance Awards. Effect of a Change in Control or Certain Other Transactions Generally, the Award agreement evidencing each Award will provide any specific terms applicable to that Award in the event of a Change in Control of the Company (as defined below). Unless otherwise provided in an Award agreement, in connection with a merger, consolidation, reorganization, recapitalization or other similar change in the capital stock of the Company, a liquidation or dissolution of the Company or a Change in Control (each, a “Corporate Transaction”), Awards will either: (a) continue following such Corporate Transaction, which may include, in the discretion of the Committee or the parties to the Corporate Transaction, the assumption, continuation or substitution of the Awards, in each case with appropriate adjustments to the number, kind of shares and exercise prices of the Awards; or (b) terminate. For purposes of the 2016 Equity Plan, “Change in Control” generally means the occurrence of any of the following events with respect to the Company: (a) any person (other than directly from the Company) first acquires securities of the Company representing fifty percent or more of the combined voting power of the Company’s then outstanding voting securities, other than an acquisition by certain employee benefit plans, the Company or a related entity or any person in connection with a non-control transaction; (b) a majority of the members of the Board is replaced by directors whose appointment or election is not endorsed by a majority of the members of the Board serving immediately prior to such appointment or election; (c) any merger, consolidation or reorganization, other than in a non-control transaction; (d) a complete liquidation or dissolution or (e) sale or disposition of all or substantially all of the assets. A “non-control transaction” generally includes any transaction in which (i) stockholders immediately before such transaction continue to own at least a majority of the combined voting power of such resulting entity following the transaction; (ii) a majority of the members of the Board immediately before such transaction continue to constitute at least a majority of the board of the surviving entity following such transaction or (iii) with certain exceptions, no person other than any person who had beneficial ownership of more than fifty percent of the combined voting power of the Company’s then outstanding voting securities immediately prior to such transaction has beneficial ownership of more than fifty percent of the combined voting power of the surviving entity’s outstanding voting securities immediately after such transaction. Transferability The 2016 Equity Plan generally restricts the transfer of any Awards, except (a) transfers by will or the laws of descent and distribution or (b) to a beneficiary designated by the participant, to whom any benefit under the 2016 Equity Plan is to be AT HOME GROUP INC. 2021 PROXY STATEMENT 81

PROPOSAL 4—AMENDMENT TO THE AMENDED AND RESTATED AT HOME GROUP INC. EQUITY INCENTIVE PLAN paid or who may exercise any rights of the participant in the event of the participant’s death before he or she receives any or all of such benefit or exercises an Award. Amendment or Termination of the 2016 Equity Plan The 2016 Equity Plan may be amended or terminated by the Board without stockholder approval unless stockholder approval of the amendment or termination is required under applicable law, regulations or NYSE requirements. No amendment may materially and adversely alter or impair any Awards that had been granted under the 2016 Equity Plan prior to the amendment without the impacted participant’s consent. The 2016 Equity Plan will terminate on the tenth anniversary of its effective date; however, when the 2016 Equity Plan terminates, any applicable terms will remain in effect for administration of any Awards outstanding at the time of the 2016 Equity Plan’s termination. Forfeiture Events; Clawback The Committee may specify in an Award agreement that the participant’s rights, payments and benefits with respect to an Award be subject to reduction, cancellation, forfeiture, clawback or recoupment upon the occurrence of certain specified events or as required by law, in addition to any otherwise applicable forfeiture provisions that apply to the Award. If a participant receives compensation pursuant to an Award under the 2016 Equity Plan based on financial statements that are subsequently required to be restated in a way that would decrease the value of such compensation, the participant will, to the extent not otherwise prohibited by law, upon the written request of the Company, forfeit and repay to the Company the difference between what the participant received and what the participant should have received based on the accounting restatement, in accordance with (i) the Company’s compensation recovery, “clawback” or similar policy, as may be in effect from time to time and (ii) any compensation recovery, “clawback” or similar policy made applicable by law including the provisions of Section 945 of the Dodd-Frank Wall Street Reform and Consumer Protection Act and the rules, regulations and requirements adopted thereunder by the SEC, the NYSE and/or any other national securities exchange on which the Company’s equity securities may be listed. FEDERAL INCOME TAX CONSEQUENCES The following is only a brief summary of the U.S. federal income tax consequences to a recipient and the Company of a stock incentive award, and does not discuss the effect of income tax law of any other jurisdiction (such as state income tax law) in which the recipient may reside. Options Options may be granted in the form of ISOs or NSOs. ISOs granted to employees are eligible for favorable federal income tax treatment that is provided under Section 422 of the Code if certain requirements are satisfied. An ISO must have an option price that is not less than the fair market value of the stock at the time the Option is granted (110% in the case of an ISO granted to a ten-percent stockholder), and must be exercisable within ten years from the date of grant (five years in the case of an ISO granted to a ten-percent stockholder). An employee granted an ISO or NSO generally does not realize compensation income for federal income tax purposes upon the grant of the Option. At the time of exercise of an ISO, no compensation income is realized by the holder of the Option other than tax preference income for purposes of the federal alternative minimum tax on individual income. If the Shares acquired on exercise of an ISO are held for at least two years after grant of the Option and one year after exercise, the excess of the amount realized on sale over the exercise price will be taxed as capital gain. If the Shares acquired on exercise of an ISO are disposed of within less than two years after grant or one year of exercise, the holder will realize taxable compensation income equal to the excess of the fair market value of the Shares on the date of exercise or the date of sale, whichever is less, over the option exercise price. Any additional amount realized will be taxed as capital gain. At the time of exercise of an NSO the holder of the Option will realize taxable compensation income in an amount of the spread between the exercise price of the Option and the fair market value of the Shares acquired on the date of exercise. The Company will be entitled to a federal income tax deduction at the time of exercise equal to the amount of compensation income that is realized by the holder of an Option. AT HOME GROUP INC. 2021 PROXY STATEMENT 82

PROPOSAL 4—AMENDMENT TO THE AMENDED AND RESTATED AT HOME GROUP INC. EQUITY INCENTIVE PLAN SARs At the time of settlement of a SAR the holder of the SAR will realize taxable compensation income in an amount equal to the spread between the base price of the SAR and the fair market value of the Shares acquired on the date of exercise. The Company will be entitled to a federal income tax deduction at the time of settlement equal to the amount of compensation income that is realized by the holder of the SAR. Restricted Stock and Performance-Based Restricted Stock Employees granted Restricted Stock or Performance-Based Restricted Stock under the 2016 Equity Plan generally recognize as taxable compensation income the fair market value of the Restricted Stock or Performance-Based Restricted Stock on the date the restrictions lapse unless the employee has elected to include the restricted award in income at the time of grant under Section 83(b) of the Code. The Company will be entitled to a federal income tax deduction at the time and in the amount of the compensation income that is recognized by the holder of the Restricted Stock or Performance-Based Restricted Stock. The Company will also be entitled to a federal income tax deduction with respect to any dividends paid to an employee during the restricted period equal to the amount of compensation income realized by the holder of the Restricted Stock or Performance-Based Restricted Stock in respect of such dividends (unless the employee has elected to include the restricted award in income when granted under Section 83(b) of the Code). RSUs, Performance Units and PSUs Employees granted RSUs, Performance Units or PSUs under the 2016 Equity Plan generally recognize as taxable compensation income the cash or the fair market value the Shares or other property paid upon settlement of the RSUs, Performance Units and PSUs. The Company will be entitled to a federal income tax deduction at the time of payment equal to the amount of compensation income realized by the holder of the RSUs, Performance Units or PSUs. The Company will also be entitled to a federal income tax deduction with respect to any dividend equivalents paid to an employee equal to the amount of compensation income realized by the holder of the RSUs, Performance Units or PSUs. Share Awards Share Awards are in the nature of Shares of the Company (as opposed to phantom stock). Employees granted Share Awards under the 2016 Equity Plan generally recognize as taxable compensation income the aggregate of fair market value of the Share Award on the date the Share Award is no longer subject to a substantial risk of forfeiture. The Company will be entitled to a federal income tax deduction at the time a Share Award is no longer subject to a substantial risk of forfeiture equal to the amount of compensation income realized by the holder of the Share Award. Excise Taxes Effects of a Change in Control on Options or other Awards, if any, may include accelerated vesting or lapse of restrictions with respect to Options or other Awards. Under certain circumstances, the accelerated vesting or lapse of restrictions with respect to Options or other Awards in connection with a Change in Control may be deemed an “excess parachute payment” for purposes of the golden parachute tax provisions of Section 280G of the Code. To the extent it is so considered, a participant may be subject to a 20% excise tax and we may be denied a tax deduction. Section 409A Section 409A of the Code generally imposes an additional 20% income tax, as well as interest and penalties, on recipients of deferred compensation that does not comply with Section 409A of the Code. “Deferred compensation” for this purpose generally consists of compensation to which an individual has a legally binding right in a taxable year and which is to be paid in a later taxable year. In addition to the taxes, interest and penalties, deferred compensation that does not comply with Section 409A of the Code may be required to be taken into income earlier than is intended. Awards under the 2016 Equity Plan are intended either not to be subject to Section 409A of the Code or to comply with Section 409A of the Code. If Awards under the 2016 Equity Plan are subject to Section 409A of the Code and do not comply with Section 409A of the Code, participants may be liable for the tax, interest and penalties imposed by the statute.

For purposes of this table, PSUs are assumed to be issuable at the maximum award amount. INTERESTS OF DIRECTORS AND EXECUTIVE OFFICERS; NEW PLAN BENEFITS Our officers, employees, non-employee directors and consultants are Eligible Individuals under the 2016 Equity Plan. Consequently, each current director and each current executive officer has a personal interest in the approval of the Amendment. However, the actual benefit and number of shares to be issued to our officers, employees, non-employee directors and consultants under the 2016 Equity Plan if the Amendment is approved cannot be determined at this time because Awards to be made under the 2016 Equity Plan have not been determined or granted and are not determinable using an objective formula. Furthermore, the additional benefits or amounts, if any, that would have been awarded to executive officers, non-executive officers, employees and directors during fiscal year 2021 if the Amendment had been in effect during such period are also not determinable. However, please refer to the section of this Proxy Statement entitled “Named Executive Officer Compensation Tables,” which provides information on the grants made in fiscal year 2021 to our named executive officers, and the section of this Proxy Statement entitled “Board Matters—Director Compensation,” which provides a description of grants made to our non-employee directors in fiscal year 2021.

ADDITIONAL INFORMATION QUESTIONS AND ANSWERS ABOUT THE PROXY MATERIALS AND THE ANNUAL MEETING Why am I receiving these materials? You are receiving these materials because at the close of business on the Record Date, you owned shares of the Company’s common stock. All stockholders of record on the Record Date, and beneficial owners on the Record Date holding a valid proxy for the Annual Meeting from their broker, bank or other nominee giving them the right to vote the shares, are entitled to attend and vote at the Annual Meeting. Each share of our common stock is entitled to vote at the Annual Meeting. As of the Record Date, we had 65,484,047 shares of common stock outstanding. With respect to each matter submitted for vote at the Annual Meeting, each share of common stock is entitled to one vote. What votes need to be present to hold the Annual Meeting? The presence at the Annual Meeting, by means of remote communication or by proxy, of stockholders holding a majority of the shares entitled to vote outstanding on the Record Date will constitute a quorum for all purposes. Proxies marked with abstentions or instructions to withhold votes, as well as broker non-votes (defined below), will be counted as present in determining whether or not there is a quorum. By a vote of the shares present, even if less than a quorum, the meeting may be adjourned to another place and time for a period not exceeding 30 days in any one case. What is the difference between holding shares as a stockholder of record and as a beneficial owner? If your shares are registered directly in your name with the Company’s transfer agent, American Stock Transfer & Trust Company, LLC, you are considered the “stockholder of record” with respect to those shares and the applicable proxy materials are being sent directly to you. If your shares are held with a broker, bank or other nominee, you are considered the “beneficial owner” with respect to those shares. The proxy materials will be forwarded to you by your broker, bank or other holder of record who is considered the stockholder of record with respect to those shares. As the beneficial owner, you have the right to direct your broker, bank or other nominee on how to vote your shares. Your broker, bank or nominee has enclosed voting instructions for you to use in directing the broker, bank or nominee on how to vote your shares. AT HOME GROUP INC. 2021 PROXY STATEMENT 86

Whether or not you plan to attend the Annual Meeting, we urge you to vote. Voting on the Internet or by telephone, or returning the proxy card, will not affect your right to attend the Annual Meeting and cast your vote electronically at the Annual Meeting. How do I vote if I am a beneficial owner? As a beneficial owner, you have the right to direct your broker, bank or other nominee how to vote your shares by following the instructions that your broker, bank or other nominee sent to you. You will receive voting instructions for each account that you have with a broker, bank or other nominee. Please instruct your broker, bank or other nominee how to vote your shares using the voting instruction form you received from them. Please return your completed voting instruction form to your broker, bank or other nominee and contact the person responsible for your account so that your vote can be counted. If your broker, bank or other nominee permits you to provide voting instructions through the Internet or by telephone, you may vote that way as well. As a beneficial owner, if you wish to change the directions that you have provided to your broker, bank or other nominee, you should follow the instructions that your broker, bank or other nominee sent to you. If you do not direct your broker, bank or other nominee how to vote your shares, the broker, bank or other nominee will determine if it has the discretionary authority to vote on each applicable matter. Under applicable law, if you are a beneficial owner, your broker, bank or other nominee only has discretion to vote on certain “routine” matters without your voting instructions. The proposal to ratify the appointment of Ernst & Young as our independent registered public accounting firm is considered a routine matter. For all other matters at the Annual Meeting, your broker, bank or other nominee will be unable to vote on your behalf if you do not instruct them how to vote your shares and, if you do not provide voting instructions, your shares will be considered “broker non-votes.” Therefore, it is very important for you to vote your shares for each proposal. What does it mean if I receive more than one Notice of Internet Availability of Proxy Materials, proxy card or voting instruction form? If you receive more than one Notice of Internet Availability of Proxy Materials, proxy card or voting instruction form, it means that you have multiple accounts with banks, brokers, other nominees and/or our transfer agent.

ADDITIONAL INFORMATION What is the voting requirement to approve each of the proposals? 1 Election of Class II Directors Plurality of the votes cast that are entitled to vote* For the director nominee(s) Against the director nominee(s) — Not a vote cast 2 Advisory Vote on Named Executive Officer Compensation Majority of the voting power present that are entitled to vote For the proposal Against the proposal Against the proposal Not entitled to vote 3 Ratification of Appointment of our Independent Registered Public Accounting Firm Majority of the voting power present that are entitled to vote For the proposal Against the proposal Against the proposal — 4 Approval of Amendment to the 2016 Equity Plan Majority of the voting power present that are entitled to vote** For the proposal Against the proposal Against the proposal Not entitled to vote * Notwithstanding that directors will be elected by a plurality of votes cast, if any director nominee receives a greater number of votes “withheld” than “for” his or her election, our majority voting policy requires such director to promptly tender his or her resignation. The Board, upon recommendation of the Nominating and Corporate Governance Committee, will determine whether to accept such resignation offer. ** NYSE rules provide that the minimum vote that constitutes approval is approval by a majority of votes cast, including abstentions (that is, the number of votes cast in favor of the proposal must exceed the aggregate of votes cast against the proposal plus abstentions). This standard does not change the treatment of abstentions or broker non-votes described above for Proposal 4. Although the advisory votes in Proposals 2 and 3 are not binding, the Board and its respective committees will take your vote into consideration in determining future activities. Who will count the votes and where can I find the voting results? The Inspector of Elections appointed at the Annual Meeting will tabulate the voting results. We intend to disclose the final voting results in a current report on Form 8-K within four business days of the Annual Meeting. To the extent final voting results are not then available, we will report preliminary voting results in a current report on Form 8-K within four business days of the Annual Meeting and report the final voting results in a current report on Form 8-K as soon as they are available. Who will pay the costs of soliciting these proxies? We will bear the entire cost of solicitation of proxies, including preparation, assembly, printing and mailing of this Proxy Statement, the proxy card, and any additional information furnished to stockholders. Copies of solicitation materials will be furnished to banks, brokers and other nominees holding shares of voting stock beneficially owned by others to forward to such beneficial owners.

No additional compensation will be paid to our directors, officers or other employees for such services. Are you “householding” for stockholders sharing the same address? The SEC’s rules permit us to deliver a single copy of the Proxy Statement and Annual Report, to an address that two or more stockholders share. This method of delivery is referred to as “householding” and can significantly reduce our printing and mailing costs and the volume of mail you receive.

Calculating Shares Available. If an Award or any portion thereof that is issued from the Post-IPO Share Pool (i) expires or otherwise terminates without all of the Shares covered by such Award having been issued or (ii) is settled in cash (i.e., the Participant receives cash rather than Shares), such expiration, termination or settlement will not reduce (or otherwise offset) the number of Shares that may be available for issuance under the Plan.

Maximum Duration. Options granted hereunder shall be for such term as the Committee shall determine; provided that an Incentive Stock Option shall not be exercisable after the expiration of ten (10) years from the date it is granted (five (5) years in the case of an Incentive Stock Option granted to a Ten-Percent Shareholder) and a Nonqualified Stock Option shall not be exercisable after the expiration of ten (10) years from the date it is granted; provided, further, however, that (i) unless the Committee provides otherwise, an Option (other than an Incentive Stock Option) may, upon the death of the Participant prior to the expiration of the Option, be exercised for up to one (1) year following the date of the Participant’s death (but in no event beyond the date on which the Option otherwise would expire by its terms), and (ii) if, at the time an Option (other than an Incentive Stock Option) would otherwise expire at the end of its term, the exercise of the Option is prohibited by applicable law or the Company’s insider trading policy, the term shall be extended until thirty (30) days after the prohibition no longer applies.

APPENDIX B—AMENDED AND RESTATED AT HOME GROUP INC. EQUITY INCENTIVE PLAN 5.5. Limitations on Incentive Stock Options.

In addition, (i) the Committee may provide for the payment of the Option Price through Share withholding as a result of which the number of Shares issued upon exercise of an Option would be reduced by a number of Shares having a Fair Market Value equal to the Option Price and (ii) an Option may be exercised through a registered broker-dealer pursuant to such cashless exercise procedures that are, from time to time, deemed acceptable by the Committee. No fractional Shares (or cash in lieu thereof) shall be issued upon exercise of an Option and the number of Shares that may be purchased upon exercise shall be rounded down to the nearest number of whole Shares. 5.7.

No Participant shall be deemed for any purpose to be the owner of any Shares subject to any Option unless and until (a) the Option shall have been exercised with respect to such Shares pursuant to the terms of the applicable Award Agreement, (b) the Company shall have issued and delivered Shares (whether or not certificated) to the Participant, a securities broker acting on behalf of the Participant or such other nominee of the Participant and (c) the Participant’s name, or the name of his or her broker or other nominee, shall have been entered as a shareholder of record on the books of the Company.

Notwithstanding the foregoing, the Committee may limit in any manner the amount payable with respect to any Stock Appreciation Right by including such a limit in the Award Agreement evidencing the Stock Appreciation Right at the time it is granted. 6.5. Method of Exercise. Stock Appreciation Rights shall be exercised by a Participant only by giving notice in the form and to the Person designated by the Company, specifying the number of Shares with respect to which the Stock Appreciation Right is being exercised. 6.6.

At the discretion of the Committee, Shares issued in connection with an Award of Performance-Based Restricted Stock may be held in escrow by an agent (which may be the Company) designated by the Committee. Unless the Committee determines otherwise and as set forth in the Award Agreement, upon issuance of the Shares, the Participant shall have all of the rights of a shareholder with respect to such Shares, including the right to vote the Shares and to receive all dividends or other distributions paid or made with respect to the Shares. (b) Terms and Conditions. Each Award Agreement shall specify the number of Shares of Performance-Based Restricted Stock to which it relates, the Performance Objectives and other conditions which must be satisfied in order for the Performance-Based Restricted Stock to vest, the Performance Cycle within which such Performance Objectives must be satisfied and the circumstances under which the Award will be forfeited; provided, however, that no Performance Cycle for Performance-Based Restricted Stock shall be less than one (1) year. (c) Treatment of Dividends. At the time the Award of Performance-Based Restricted Stock is granted, the Committee may, in its discretion, determine that the payment to the Participant of dividends, or a specified portion thereof, declared or paid on Shares represented by such Award which have been issued by the Company to the Participant shall be (i) deferred until the lapsing of the restrictions imposed upon such Performance-Based Restricted Stock and (ii) held by the Company for the account of the Participant until such time; provided, however, that a dividend payable in respect of Performance-Based Restricted Stock shall be subject to restrictions and risk of forfeiture to the same extent as the Performance-Based Restricted Stock with respect to which such dividends are payable. In the event that dividends are to be deferred, the Committee shall determine whether such dividends are to be reinvested in Shares (which shall be held as additional Shares of Performance-Based Restricted Stock) or held in cash. Payment of deferred dividends in respect AT HOME GROUP INC. 2021 PROXY STATEMENT B-12

APPENDIX B—AMENDED AND RESTATED AT HOME GROUP INC. EQUITY INCENTIVE PLAN of Shares of Performance-Based Restricted Stock (whether held in cash or in additional Shares of Performance-Based Restricted Stock) shall be made upon the lapsing of restrictions imposed on the Performance-Based Restricted Stock in respect of which the deferred dividends were paid, and any dividends deferred in respect of any Performance-Based Restricted Stock shall be forfeited upon the forfeiture of such Performance-Based Restricted Stock. (d) Delivery of Shares. Upon the lapse of the restrictions on Shares of Performance-Based Restricted Stock awarded hereunder, the Committee shall cause a stock certificate or evidence of book entry Shares to be delivered to the Participant with respect to such Shares, free of all restrictions hereunder. 9.3. Performance Objectives. (a) Establishment. With respect to any Performance Awards intended to constitute Performance-Based Compensation, Performance Objectives for Performance Awards may be expressed in terms of (i) earnings per share; (ii) operating income; (iii) return on equity or assets; (iv) cash flow; (v) net cash flow; (vi) cash flow from operations; (vii) EBITDA and/or adjusted EBITDA; (viii) revenue growth, product revenue and/or comparable sales growth; (ix) revenue ratios; (x) cost reductions; (xi) cost ratios or margins; (xii) overall revenue or sales growth; (xiii) expense reduction or management; (xiv) market position or market share; (xv) total shareholder return; (xvi) return on investment; (xvii) earnings before interest and taxes (EBIT); (xviii) net income (before or after taxes); (xix) return on assets or net assets; (xx) economic value added; (xxi) shareholder value added; (xxii) cash flow return on investment; (xxiii) net operating profit; (xxiv) net operating profit after tax; (xxv) return on capital; (xxvi) return on invested capital; (xxvii) customer growth; (xxviii) supply chain achievements, (xxix) financial ratios, including those measuring liquidity, activity, profitability or leverage; (xxx) financing and other capital raising transactions (xxxi) strategic partnerships or transactions; or (xxxii) any combination of the foregoing. With respect to Performance Awards not intended to constitute Performance-Based Compensation, Performance Objectives may be based on any of the foregoing or any other performance criteria as may be established by the Committee. Performance Objectives may be in respect of the performance of the Company, any of its Subsidiaries, any of its Divisions or any combination thereof. Performance Objectives may be absolute or relative (to prior performance of the Company or to the performance of one or more other entities or external indices) and may be expressed in terms of a progression within a specified range. In the case of a Performance Award which is intended to constitute Performance-Based Compensation, the Performance Objectives with respect to a Performance Cycle shall be established in writing by the Committee by the earlier of (i) the date on which a quarter of the Performance Cycle has elapsed and (ii) the date which is ninety (90) days after the commencement of the Performance Cycle and in any event while the performance relating to the Performance Objectives remains substantially uncertain. (b) Effect of Certain Events. The Committee may, at the time the Performance Objectives in respect of a Performance Award are established, provide for the manner in which performance will be measured against the Performance Objectives to reflect the impact of specified events, including any one or more of the following with respect to the Performance Period (i) the gain, loss, income or expense resulting from changes in accounting principles or tax laws that become effective during the Performance Period; (ii) the gain, loss, income or expense reported publicly by the Company with respect to the Performance Period that are extraordinary or unusual in nature or infrequent in occurrence; (iii) the gains or losses resulting from and the direct expenses incurred in connection with, the disposition of a business, or the sale of investments or non-core assets; (iv) the gain or loss from all or certain claims and/or litigation and all or certain insurance recoveries relating to claims or litigation; or (v) the impact of investments or acquisitions made during the year or, to the extent provided by the Committee, any prior year. The events may relate to the Company as a whole or to any part of the Company’s business or operations, as determined by the Committee at the time the Performance Objectives are established. Any adjustments based on the effect of certain events are to be determined in accordance with generally accepted accounting principles and standards, unless another objective method of measurement is designated by the Committee and, in respect of Performance Awards intended to constitute Performance-Based Compensation, such adjustments shall be permitted only to the extent permitted under Section 162(m) without adversely affecting the treatment of any Performance Award as Performance-Based Compensation. (c) Determination of Performance. Prior to the vesting, payment, settlement or lapsing of any restrictions with respect to any Performance Award, the Committee shall certify in writing that the applicable Performance Objectives have been satisfied to the extent necessary for such Award to qualify as Performance-Based Compensation. In respect of a Performance Award, the Committee may, in its sole discretion, (i) reduce the amount of cash paid or number of Shares to be issued or that have been issued and that become vested or on which restrictions lapse, and/or (ii) establish rules and procedures that have the effect of limiting the amount payable to any Participant to an amount that is less AT HOME GROUP INC. 2021 PROXY STATEMENT B-13

APPENDIX B—AMENDED AND RESTATED AT HOME GROUP INC. EQUITY INCENTIVE PLAN than the amount that otherwise would be payable under an Award granted under this Section 9. The Committee may exercise such discretion in a non-uniform manner among Participants. The Committee shall not be entitled to exercise any discretion otherwise authorized hereunder with respect to any Performance Award intended to constitute Performance-Based Compensation if the ability to exercise such discretion or the exercise of such discretion itself would cause the compensation attributable to such Awards to fail to qualify as Performance-Based Compensation. (d) Effect of Change in Control. Any specific terms applicable to a Performance Award in the event of a Change in Control and not otherwise provided in the Plan shall be set forth in the applicable Award Agreement. 10. Share Awards. The Committee may grant a Share Award to any Eligible Individual on such terms and conditions as the Committee may determine in its sole discretion. Share Awards may be made as additional compensation for services rendered by the Eligible Individual or may be in lieu of cash or other compensation to which the Eligible Individual is entitled from the Company. Any dividend payable in respect of a Share Award that vests based on the achievement of performance goals shall be subject to restrictions and risk of forfeiture to the same extent as the Share Award with respect to which such dividends are payable. 11. Effect of Termination of Employment; Transferability. 11.1. Termination. The Award Agreement evidencing the grant of each Award shall set forth the terms and conditions applicable to such Award upon Termination, which shall be as the Committee may, in its discretion, determine at the time the Award is granted or at anytime thereafter. 11.2. Transferability of Awards and Shares. (a) Non-Transferability of Awards. Except as set forth in Section 11.2(c) or (d) or as otherwise permitted by the Committee and as set forth in the applicable Award Agreement, either at the time of grant or at anytime thereafter, no Award (other than Restricted Stock, Performance-Based Restricted Stock, and Share Awards with respect to which the restrictions have lapsed) shall be (i) sold, transferred or otherwise disposed of, (ii) pledged or otherwise hypothecated or (iii) subject to attachment, execution or levy of any kind; and any purported transfer, pledge, hypothecation, attachment, execution or levy in violation of this Section 11.2 shall be null and void. (b) Restrictions on Shares. The Committee may impose such restrictions on any Shares acquired by a Participant under the Plan as it may deem advisable, including, without limitation, minimum holding period requirements, restrictions under applicable federal securities laws, restrictions under the requirements of any stock exchange or market upon which such Shares are then listed or traded and restrictions under any blue sky or state securities laws applicable to such Shares. (c) Transfers By Will or by Laws of Descent or Distribution. Any Award may be transferred by will or by the laws of descent or distribution; provided, however, that (i) any transferred Award will be subject to all of the same terms and conditions as provided in the Plan and the applicable Award Agreement; and (ii) the Participant’s estate or beneficiary appointed in accordance with this Section 11.2(c) will remain liable for any withholding tax that may be imposed by any federal, state or local tax authority. (d) Beneficiary Designation. To the extent permitted by applicable law, the Company may from time to time permit each Participant to name one or more individuals (each, a “Beneficiary”) to whom any benefit under the Plan is to be paid or who may exercise any rights of the Participant under any Award granted under the Plan in the event of the Participant’s death before he or she receives any or all of such benefit or exercises such Award. Each such designation shall revoke all prior designations by the same Participant, shall be in a form prescribed by the Company, and will be effective only when filed by the Participant in writing with the Company during the Participant’s lifetime. In the absence of any such designation or if any such designation is not effective under applicable law as determined by the Committee, benefits under Awards remaining unpaid at the Participant’s death and rights to be exercised following the Participant’s death shall be paid to or exercised by the Participant’s estate. 12. Adjustment upon Changes in Capitalization. 12.1. In the event that (a) the outstanding Shares are changed into or exchanged for a different number or kind of Shares or other stock or securities or other equity interests of the Company or another corporation or entity, whether AT HOME GROUP INC. 2021 PROXY STATEMENT B-14

Any such adjustment in the Shares or other stock or securities (a) subject to outstanding Incentive Stock Options (including any adjustments in the exercise price) shall be made in a manner intended not to constitute a modification as defined by Section 424(h)(3) of the Code and only to the extent otherwise permitted by Sections 422 and 424 of the Code, (b) subject to outstanding Awards that are intended to qualify as Performance-Based Compensation shall be made in a manner intended not to adversely affect the treatment of the Awards as Performance-Based Compensation and (c) with respect to any Award that is not subject to Section 409A, in a manner intended not to subject the Award to Section 409A and, with respect to any Award that is subject to Section 409A, in a manner intended to comply with Section 409A. 12.3. If, by reason of an Adjustment Event, pursuant to an Award, a Participant shall be entitled to, or shall be entitled to exercise an Award with respect to, new, additional or different shares of stock or securities of the Company or any other corporation, such new, additional or different shares shall thereupon be subject to all of the conditions, restrictions and performance criteria which were applicable to the Shares subject to the Award prior to such Adjustment Event, as may be adjusted in connection with such Adjustment Event in accordance with this Section 12. 13. Effect of Certain Transactions. 13.1. Except as otherwise provided in the applicable Award Agreement, in connection a Corporate Transaction, either: (a) outstanding Awards shall, unless otherwise provided in connection with the Corporate Transaction, continue following the Corporate Transaction and shall be adjusted if and as provided for in the agreement or plan (in the case of a liquidation or dissolution) entered into or adopted in connection with the Corporate Transaction (the “Transaction Agreement”), which may include, in the sole discretion of the Committee or the parties to the Corporate Transaction, the assumption or continuation of such Awards by, or the substitution for such Awards of new awards of, the surviving, successor or resulting entity, or a parent or subsidiary thereof, with such adjustments as to the number and kind of shares or other securities or property subject to such new awards, exercise prices and other terms of such new awards as the Committee or the parties to the Corporate Transaction shall agree, or (b) outstanding Awards shall terminate upon the consummation of the Corporate Transaction; provided, however, that vested Awards shall not be terminated without: (i) in the case of vested Options and Stock Appreciation Rights (including those Options and Stock Appreciation Rights that would become vested upon the consummation of the Corporate Transaction), (1) providing the holders of affected Options and Stock Appreciation Rights a period of at least fifteen (15) calendar days prior to the date of the consummation of the Corporate Transaction to exercise the Options and Stock Appreciation Rights, or (2) providing the holders of affected Options and Stock Appreciation Rights payment (in cash or other consideration upon or immediately following the consummation of the Corporate Transaction, or, to the extent permitted by Section 409A, on a deferred basis) in respect of each Share covered by the Option or Stock Appreciation Rights being cancelled an amount equal to the excess, if any, of the per Share price to be paid or distributed to stockholders in the Corporate Transaction (the value of any non-cash consideration to be determined by the Committee in good faith) over the Option Price of the Option or the Base Price of the Stock Appreciation Rights, or (ii) in the case of vested Awards other than Options or Stock Appreciation Rights (including those Awards that would become vested upon the consummation of the Corporate Transaction), providing the holders of affected Awards payment (in cash or other consideration upon or immediately following the consummation of the Corporate Transaction, or, to the extent permitted by Section 409A, on a deferred basis) in respect of each Share covered by the AT HOME GROUP INC. 2021 PROXY STATEMENT B-15

(c) For the avoidance of doubt, if the amount determined pursuant to clause (b)(i)(2) above is zero or less, the affected Option or Stock Appreciation Rights may be terminated without any payment therefor. 13.2. Without limiting the generality of the foregoing or being construed as requiring any such action, in connection with any such Corporate Transaction the Committee may, in its sole and absolute discretion, cause any of the following actions to be taken effective upon or at any time prior to any Corporate Transaction (and any such action may be made contingent upon the occurrence of the Corporate Transaction): (a) cause any or all unvested Options and Stock Appreciation Rights to become fully vested and immediately exercisable (as applicable) and/or provide the holders of such Options and Stock Appreciation Rights a reasonable period of time prior to the date of the consummation of the Corporate Transaction to exercise the Options and Stock Appreciation Rights; (b) with respect to unvested Options and Stock Appreciation Rights that are terminated in connection with the Corporate Transaction, provide to the holders thereof a payment (in cash and/or other consideration) in respect of each Share covered by the Option or Stock Appreciation Right being terminated in an amount equal to all or a portion of the excess, if any, of the per Share price to be paid or distributed to stockholders in the Corporate Transaction (the value of any non-cash consideration to be determined by the Committee in good faith) over the exercise price of the Option or the Base Price of the Stock Appreciation Right, which may be paid in accordance with the vesting schedule of the Award as set forth in the applicable Award Agreement, upon the consummation of the Corporate Transaction or, to the extent permitted by Section 409A, at such other time or times as the Committee may determine; (c) with respect to unvested Awards (other than Options or Stock Appreciation Rights) that are terminated in connection with the Corporate Transaction, provide to the holders thereof a payment (in cash and/or other consideration) in respect of each Share covered by the Award being terminated in an amount equal to all or a portion of the per Share price to be paid or distributed to stockholders in the Corporate Transaction (the value of any non-cash consideration to be determined by the Committee in good faith), which may be paid in accordance with the vesting schedule of the Award as set forth in the applicable Award Agreement, upon the consummation of the Corporate Transaction or, to the extent permitted by Section 409A, at such other time or times as the Committee may determine. (d) For the avoidance of doubt, if the amount determined pursuant to clause (b) above is zero or less, the affected Option or Stock Appreciation Rights may be terminated without any payment therefor. 13.3. Notwithstanding anything to the contrary in this Plan or any Agreement, (a) the Committee may, in its sole discretion, provide in the Transaction Agreement or otherwise for different treatment for different Awards or Awards held by different Participants and, where alternative treatment is available for a Participant’s Awards, may allow the Participant to choose which treatment shall apply to such Participant’s Awards; (b) any action permitted under this Section 13 may be taken without the need for the consent of any Participant. To the extent a Corporate Transaction also constitutes an Adjustment Event and action is taken pursuant to this Section 13 with respect to an outstanding Award, such action shall conclusively determine the treatment of such Award in connection with such Corporate Transaction notwithstanding any provision of the Plan to the contrary (including Section 12). (c) to the extent the Committee chooses to make payments to affected Participants pursuant to Section 13.1(b)(i)(2) or (ii) or Section 13.2(b) or (c) above, any Participant who has not returned any letter of transmittal or similar acknowledgment that the Committee requires be signed in connection with such payment within the time period established by the Committee for returning any such letter or similar acknowledgement shall forfeit his or her right to any payment and his or her associated Awards may be cancelled without any payment therefor. 14. Interpretation. 14.1. Section 16 Compliance. The Plan is intended to comply with Rule 16b-3 promulgated under the Exchange Act and the Committee shall interpret and administer the provisions of the Plan or any Award Agreement in a manner consistent therewith. Any provisions inconsistent with such Rule shall be inoperative and shall not affect the validity of the Plan. AT HOME GROUP INC. 2021 PROXY STATEMENT B-16

APPENDIX B—AMENDED AND RESTATED AT HOME GROUP INC. EQUITY INCENTIVE PLAN 14.2. Compliance with Section 409A. All Awards granted under the Plan are intended either not to be subject to Section 409A or, if subject to Section 409A, to be administered, operated and construed in compliance with Section 409A. Notwithstanding this or any other provision of the Plan or any Award Agreement to the contrary, the Committee may amend the Plan or any Award granted hereunder in any manner or take any other action that it determines, in its sole discretion, is necessary, appropriate or advisable (including replacing any Award) to cause the Plan or any Award granted hereunder to comply with Section 409A and all regulations and other guidance issued thereunder or to not be subject to Section 409A. Any such action, once taken, shall be deemed to be effective from the earliest date necessary to avoid a violation of Section 409A and shall be final, binding and conclusive on all Eligible Individuals and other individuals having or claiming any right or interest under the Plan. 14.3. Section 162(m). (a) Performance-Based Compensation Awards. Unless otherwise determined by the Committee in its sole discretion and subject to Section 14.3(b), each Performance Award granted to an Eligible Individual who is also a Covered Employee, and each Option and Stock Appreciation Right (whether or not granted to a Covered Employee), is intended to constitute Performance-Based Compensation; provided, that no Award granted following the Transition Period shall be intended to constitute Performance-Based Compensation unless the stockholder approval and other requirements of Section 162(m) to enable Awards to qualify as Performance-Based Compensation have been satisfied. If any provision of the Plan or any Award Agreement relating to an Award that is intended to constitute Performance-Based Compensation does not comply or is inconsistent with Section 162(m), such provision shall be construed or deemed amended to the extent necessary to conform to such requirements and, in the case of any Performance Award, no provision of the Plan or any Award Agreement shall be deemed to confer upon the Committee any discretion to increase the amount of compensation otherwise payable in connection with any such Award upon the attainment of the Performance Objectives. (b) Section 162(m) Transition Period. (i) With respect to Options, Stock Appreciation Rights, Restricted Stock and Performance-Based Restricted Stock granted during the Transition Period (“Transition Awards”), the Company intends to rely, to the maximum extent possible, on the transition relief provided in Treas. Reg. §1.162-27(f). Accordingly, to the extent such relief from the application of Section 162(m) is available, the requirements in this Plan applicable to Awards intended to constitute Performance-Based Compensation shall not apply to Transition Awards which, without limiting the generality of the foregoing, include the provisions of Section 4.2 and those provisions of Sections 3.1(b), 3.3(a) and 9 that apply only to Awards intended to constitute Performance-Based Compensation. (ii) With respect to Awards other than Transition Awards granted during the Transition Period and which are not settled or paid prior to the end of the Transition Period, and with respect to all Awards granted following the Transition Period, the stockholder approval and other requirements of Section 162(m) must be satisfied with respect to any Awards intended to qualify as Performance-Based Compensation. 15. Term; Plan Termination and Amendment of the Plan; Modification of Awards. 15.1. Term. The Plan shall terminate on the Plan Termination Date and no Award shall be granted after that date. The applicable terms of the Plan and any terms and conditions applicable to Awards granted prior to the Plan Termination Date shall survive the termination of the Plan and continue to apply to such Awards. 15.2. Plan Amendment or Plan Termination. The Board may earlier terminate the Plan and the Board may at any time and from time to time amend, modify or suspend the Plan; provided, however, that: (a) except as otherwise provided in Section 14.2, no such amendment, modification, suspension or termination shall materially and adversely alter any Awards theretofore granted under the Plan, except with the consent of the Participant, nor shall any amendment, modification, suspension or termination deprive any Participant of any Shares which he or she may have acquired through or as a result of the Plan; and (b) to the extent necessary under any applicable law, regulation or exchange requirement or as provided in Section 3.7, no other amendment shall be effective unless approved by the stockholders of the Company in accordance with applicable law, regulation or exchange requirement.

APPENDIX B—AMENDED AND RESTATED AT HOME GROUP INC. EQUITY INCENTIVE PLAN 15.3. Modification of Awards. No modification of an Award shall materially and adversely alter or impair any rights or obligations under the Award without the consent of the Participant. 16. Non-Exclusivity of the Plan. The adoption of the Plan by the Board shall not be construed as amending, modifying or rescinding any previously approved incentive arrangement or as creating any limitations on the power of the Board to adopt such other incentive arrangements as it may deem desirable, including, without limitation, the granting of stock options otherwise than under the Plan, and such arrangements may be either applicable generally or only in specific cases. 17. Limitation of Liability. As illustrative of the limitations of liability of the Company, but not intended to be exhaustive thereof, nothing in the Plan shall be construed to: (a) give any person any right to be granted an Award other than at the sole discretion of the Committee; (b) limit in any way the right of the Company or any of its Subsidiaries to terminate the employment of or the provision of services by any person at any time; (c) be evidence of any agreement or understanding, express or implied, that the Company will pay any person at any particular rate of compensation or for any particular period of time; or (d) be evidence of any agreement or understanding, express or implied, that the Company will employ any person at any particular rate of compensation or for any particular period of time. 18.

Except as to matters of federal law, the Plan and the rights of all persons claiming hereunder shall be construed and determined in accordance with the laws of the State of Delaware without giving effect to conflicts of laws principles thereof. 18.2. Compliance with Law. (a) The obligation of the Company to sell or deliver Shares with respect to Awards granted under the Plan shall be subject to all applicable laws, rules and regulations, including all applicable federal and state securities laws, and the obtaining of all such approvals by governmental agencies as may be deemed necessary or appropriate by the Committee. (b) The Board may make such changes as may be necessary or appropriate to comply with the rules and regulations of any government authority or to obtain for Eligible Individuals granted Incentive Stock Options the tax benefits under the applicable provisions of the Code and regulations promulgated thereunder. (c) Each grant of an Award and the issuance of Shares or other settlement of the Award is subject to compliance with all applicable federal, state and foreign law. Further, if at any time the Committee determines, in its discretion, that the listing, registration or qualification of Shares issuable pursuant to the Plan is required by any securities exchange or under any federal, state or foreign law, or that the consent or approval of any governmental regulatory body is necessary or desirable as a condition of, or in connection with, the grant of an Award or the issuance of Shares, no Awards shall be or shall be deemed to be granted or payment made or Shares issued, in whole or in part, unless listing, registration, qualification, consent or approval has been effected or obtained free of any conditions that are not acceptable to the Committee. Any person exercising an Option or receiving Shares in connection with any other Award shall make such representations and agreements and furnish such information as the Board or Committee may request to assure compliance with the foregoing or any other applicable legal requirements. 18.3. Transfers of Plan Acquired Shares. Notwithstanding anything contained in the Plan or any Award Agreement to the contrary, in the event that the disposition of Shares acquired pursuant to the Plan is not covered by a then current AT HOME GROUP INC. 2021 PROXY STATEMENT B-18

APPENDIX B—AMENDED AND RESTATED AT HOME GROUP INC. EQUITY INCENTIVE PLAN registration statement under the Securities Act and is not otherwise exempt from such registration, such Shares shall be restricted against transfer to the extent required by the Securities Act and Rule 144 or other regulations promulgated thereunder. The Committee may require any individual receiving Shares pursuant to an Award granted under the Plan, as a condition precedent to receipt of such Shares, to represent and warrant to the Company in writing that the Shares acquired by such individual are acquired without a view to any distribution thereof and will not be sold or transferred other than pursuant to an effective registration thereof under the Securities Act or pursuant to an exemption applicable under the Securities Act or the rules and regulations promulgated thereunder. The certificates evidencing any of such Shares shall be appropriately amended or have an appropriate legend placed thereon to reflect their status as restricted securities as aforesaid. 19. Miscellaneous. 19.1. Award Agreements. Each Award Agreement shall either be (a) in writing in a form approved by the Committee and executed on behalf of the Company by an officer duly authorized to act on its behalf, or (b) an electronic notice in a form approved by the Committee and recorded by the Company (or its designee) in an electronic recordkeeping system used for the purpose of tracking Awards as the Committee may provide. If required by the Committee, an Award Agreement shall be executed or otherwise electronically accepted by the recipient of the Award in such form and manner as the Committee may require. The Committee may authorize any officer of the Company to execute any or all Award Agreements on behalf of the Company. 19.2. Forfeiture Events; Clawback. (a) Forfeiture Events. The Committee may specify in an Award Agreement that the Participant’s rights, payments, and benefits with respect to an Award shall be subject to reduction, cancellation, forfeiture, clawback or recoupment upon the occurrence of certain specified events or as required by law, in addition to any otherwise applicable forfeiture provisions that apply to the Award. (b) Accounting Restatement. If a Participant receives compensation pursuant to an Award under the Plan based on financial statements that are subsequently required to be restated in a way that would decrease the value of such compensation, the Participant will, to the extent not otherwise prohibited by law, upon the written request of the Company, forfeit and repay to the Company the difference between what the Participant received and what the Participant should have received based on the accounting restatement, in accordance with (i) the Company’s compensation recovery, “clawback” or similar policy, as may be in effect from time to time and (ii) any compensation recovery, “clawback” or similar policy made applicable by law including the provisions of Section 954 of the Dodd-Frank Wall Street Reform and Consumer Protection Act and the rules, regulations and requirements adopted thereunder by the Securities and Exchange Commission and/or any national securities exchange on which the Company’s equity securities may be listed (the “Policy”). By accepting an Award hereunder, the Participant acknowledges and agrees that the Policy shall apply to such Award, and all incentive-based compensation payable pursuant to such Award shall be subject to forfeiture and repayment pursuant to the terms of the Policy. 19.3. Multiple Agreements. The terms of each Award may differ from other Awards granted under the Plan at the same time or at some other time. The Committee may also grant more than one Award to a given Eligible Individual during the term of the Plan, either in addition to or, subject to Section 3.7, in substitution for one or more Awards previously granted to that Eligible Individual. 19.4. Withholding of Taxes. The Company or any of its Subsidiaries may withhold from any payment of cash or Shares to a Participant or other Person under the Plan an amount sufficient to cover any withholding taxes which may become required with respect to such payment or take any other action it deems necessary to satisfy any income or other tax withholding requirements as a result of the grant, exercise, vesting or settlement of any Award under the Plan. The Company or any of its Subsidiaries shall have the right to require the payment of any such taxes or to withhold from wages or other amounts otherwise payable to a Participant or other Person, and require that the Participant or other Person furnish all information deemed necessary by the Company or any of its Subsidiaries to meet any tax reporting obligation as a condition to exercise or before making any payment or the issuance or release of any Shares pursuant to an Award. If the Participant or other Person shall fail to make such tax payments as are required, the Company or its Subsidiaries shall, to the extent permitted by law, have the right to deduct any such taxes from any payment of any kind otherwise due to such AT HOME GROUP INC. 2021 PROXY STATEMENT B-19

APPENDIX B—AMENDED AND RESTATED AT HOME GROUP INC. EQUITY INCENTIVE PLAN Participant or other Person or to take such other action as may be necessary to satisfy such withholding obligations. If specified in an Award Agreement at the time of grant or otherwise approved by the Committee in its sole discretion, a Participant may, in satisfaction of his or her obligation to pay withholding taxes in connection with the exercise, vesting or other settlement of an Award, elect to (i) make a cash payment to the Company, (ii) have withheld a portion of the Shares then issuable to him or her or (iii) deliver Shares owned by the Participant prior to the exercise, vesting or other settlement of an Award, in each case having an aggregate Fair Market Value equal to the withholding taxes. To the extent that Shares are used to satisfy withholding obligations of a Participant pursuant to this Section 19.4 (whether previously-owned Shares or Shares withheld from an Award), they may only be used to satisfy the minimum tax withholding required by law (or such other amount as will not have any adverse accounting impact as determined by the Committee). 19.5. Disposition of ISO Shares. If a Participant makes a disposition, within the meaning of Section 424(c) of the Code and regulations promulgated thereunder, of any Share or Shares issued to such Participant pursuant to the exercise of an Incentive Stock Option within the two-year period commencing on the day after the date of the grant or within the one-year period commencing on the day after the date of transfer of such Share or Shares to the Participant pursuant to such exercise, the Participant shall, within ten (10) days of such disposition, notify the Company thereof, by delivery of written notice to the Company at its principal executive office. 19.6.
