Letter to Stockholders April 15, 2022 To Our Stockholders: You are cordially invited to attend the annual meeting of stockholders (the “Annual Meeting”) of Compass, Inc. (“Compass”), which will be held virtually on Thursday, June 2, 2022 at 1:30 p.m. Eastern Time. Please see additional information about our Annual Meeting in the section entitled “Important Information About Annual Meeting” in the proxy statement. 2021 has been a year unlike any other. 2021 was a transformational year for our company. As Founder and Chief Executive Officer, I am especially proud of our team of more than 26,000 real estate professionals and over 4,000 employees for the progress we have made together in a market environment unlike anything we have ever seen. We are doing what we said we would do when we became a public company, and we are doing it quickly. In our first year as a public company, this team delivered our first full year of Adjusted EBITDA profitability, despite our net loss on GAAP basis as we continued to invest in the growth of the business. Last year our revenue grew 73%, and Compass agents facilitated $254 billion in real estate sales volume, making us the number one real estate brokerage in the United States by sales volume. I invite you to read our accompanying Annual Report on Form 10-K for more information about our financial performance in 2021. I am proud of the team for achieving Adjusted EBITDA profitability in 2021, two years ahead of plan, and we have outlined a clear pathway to further EBITDA expansion while generating positive free cash flow in the years to come. We continue to expand our offering across the United States, covering nearly half the population at the end of 2021. And we have already become the number one brokerage in the United States by sales volume in just 9 years. Becoming the number one brokerage after being in business for less than a decade is an incredible milestone, but more importantly a powerful validation of our strategy to serve and empower real estate agents with the best tools and services to grow their businesses. The key to our vision is grounded in serving a community of professionals who have been underserved for decades. At Compass, we hire the best agents in the country and provide them with an integrated technology platform, a national network of colleagues and the coaching and support that helps them grow their business faster than the rest of the industry. Our agents come to Compass and they stay: our retention rates are above 90%, leading the industry. But we did not stop with a healthy and growing brokerage business. We opened title and escrow businesses in 9 markets along with the District of Columbia, and launched a mortgage business that has already made its first loans as we work to roll it out across the country. In concert with the growth in our business, our progress in building the most comprehensive single platform for real estate agents has been astonishing. Our research indicates that agents who use the Compass platform more frequently than those who do not tend to grow their businesses at an accelerated rate. Our technology team listens to the needs of Compass agents on an ongoing basis which enables it to continuously improve our platform and support the company’s position as an industry leader in scale and integration. We are proud to have built a connected, end-to-end platform that can facilitate the entirety of the real estate transaction in one place, empowering agents to grow their businesses faster, and serve their clients better.

Looking forward to the future. The future of Compass is bright. We continue to set bold goals for our business and our technology, so that our agents can dream big and achieve their own bold goals for their businesses. Our platform will be available to every agent at Compass this summer. It will enable agents to support the entirety of the real estate transaction without leaving the platform, to make them more efficient than ever before at serving their clients with excellence. Our advanced, artificial intelligence-powered tools will continue to help our agents unlock new opportunities and serve their clients in new ways. And our title and escrow and mortgage businesses will continue to become available in new markets across the United States, allowing us to capture a larger share of the overall economic opportunity surrounding real estate transactions.

INDEPENDENCE AGE DIVERSITY * one of our directors chose not to disclose their gender and racial/ethnic background in the annual questionnaire and they are included in the “Non-diverse” category. Director Nominees At the recommendation of our Nominating and Corporate Governance Committee, our Board of Directors proposes that l Robert Reffkin, current Class I Director and Chairman of the Board of Directors and Chief Executive Officer, and l Frank Martell, current Class I Director, be elected as Class I Directors for a three-year term expiring at the 2025 annual meeting of stockholders and until such director’s successor is duly elected and qualified or until such director’s earlier death, resignation, disqualification, or removal. Our Nominating and Corporate Governance Committee and Board of Directors evaluated each of the director nominees and concluded that it is in the best interests of the Company and our stockholders for each of these individuals to continue to serve as a director. The Board of Directors believes that each director nominee brings a range of relevant experiences and overall diversity of perspectives that is essential to good governance and leadership of our company. Each person nominated for election has agreed to serve if elected, and management and the Board of Directors have no reason to believe that the director nominees will be unable to serve. If, however, prior to the Annual Meeting, the Board of Directors should learn that a director nominee will be unable to serve for any reason, the proxies that otherwise would have been voted for this nominee will be voted for a substitute nominee as selected by the Board of Directors. Alternatively, the proxies, at the Board of Director’s discretion, may be voted for no director nominees as a result of the inability of the nominee to serve. Each director nominee has consented to being named in this proxy statement and to serve if elected. Vote Required The election of director nominees requires a plurality of the votes cast by the holders of the shares of our common stock presented virtually or represented by proxy at the Annual Meeting and entitled to vote thereon. This means that the two nominees receiving the highest number of “FOR” votes will be elected as Class I Directors. Abstentions and “broker non-votes” will have no effect on the outcome of the vote 86% Independent Independent (6) Non-Independent (1) Avg.

Director Independence Under the listing rules of the New York Stock Exchange (“NYSE”) and our Corporate Governance Guidelines, our Board of Directors must consist of a majority of independent directors at all times. This means, generally, that they will not have any connections to us that could affect their ability to provide impartial oversight. A director will be deemed “independent” only if the Board of Directors affirmatively determines that the director has no material relationship with us that affects the director’s independence from management (either directly or as a partner, stockholder or officer of an organization that has a relationship with us) or that would interfere with the director exercising independent judgment in carrying out the director’s responsibilities. Additionally, under the NYSE listing rules, our audit, compensation, and nominating and corporate governance committees must consist only of independent directors and under the rules of the Securities Exchange Act of 1934, as amended (the “Exchange Act”), our audit committee members must also satisfy additional independence criteria. Our Board of Directors undertakes an annual review of the independence of each director and considers whether each director has a material relationship with us that could compromise his or her ability to exercise independent judgment in carrying out the director’s responsibilities. Based on the most recent review, our Board of Directors determined that every director except Mr. Reffkin, our Chief Executive Officer, is independent under the NYSE listing rules and our Corporate Governance Guidelines. In making these determinations, our Board of Directors reviewed and discussed information provided by the directors in an annual questionnaire with regard to each director’s business and personal activities and current and prior relationships as they may relate to us and our management. Additionally, our Board of Directors undertakes an annual review to ensure that our audit, compensation, and nominating and corporate governance committees consist only of independent directors and our audit committee members satisfy additional independence criteria under the Exchange Act rules. Based on the most recent review, our Board of Directors determined that each director serving on our audit, compensation, and nominating and corporate governance committees is independent under the NYSE listing rules and our Corporate Governance Guidelines and each director serving on our audit committee satisfies additional independence criteria under the Exchange Act rules. Board Leadership Structure Under our Corporate Governance Guidelines, the Chairperson of our Board of Directors can be our Chief Executive Officer and in accordance with our Bylaws, the Board of Directors is free to choose its Chairperson in any way that the Board of Directors considers to be in our best interests. However, if the Chairperson of the Board of Directors also serves as our Chief Executive Officer or any other Executive Officer, the Board of Directors, by a majority vote of the independent directors, is required to designate a Lead Independent Director. Under our Corporate Governance Guidelines, a Lead Independent Director will preside over periodic meetings of our independent directors, serve as a liaison between the Chairperson of our Board of Directors and the independent directors, and management and the independent directors, and perform such additional duties as our Board of Directors may otherwise determine and delegate. Our Nominating and Corporate Governance Committee periodically considers the leadership structure of our Board of Directors, including the separation of the Chairperson and Chief Executive Officer roles or the appointment of a Lead Independent Director, either permanently or for specific purposes, and make such recommendations to the Board of Directors with respect thereto as the Nominating and Corporate Governance Committee deems appropriate. Based on the most recent review, our Nominating and Corporate Governance Committee and Board of Directors determined that the current leadership structure of our Board of Directors, where Mr. Reffkin, our Chief Executive Officer, serves as the Chairman of the Board of Directors and Mr. Phillips serves as the Lead Independent Director, 12 2022 PROXY STATEMENT Toppan Merrill - Compass_ Inc DEF 14A ED | 111292 | 15-Apr-22 00:50 | 22-10332-1.da | Sequence: 7 CHKSUM Content: 56828 Layout: 31490 Graphics: 0 CLEAN JOB: 22-10332-1 CYCLE#;BL#: 9; 0 TRIM: 8.25" x 10.75" AS: New York: 212-620-5600 COLORS: Black, ~note-color 2 GRAPHICS: none V1.5

continues to be appropriate because it allows our Chief Executive Officer/Chairman of the Board of Directors to lead our company with a cohesive business strategy and provides the necessary flexibility to rapidly address the changing needs of our business as our business strategy evolves. It also fosters clear accountability and effective decision-making. Additionally, Mr. Phillips’ strong leadership provides for a healthy balance and effective oversight of our company. Board Committees The Board of Directors has three principal standing committees: the Audit Committee, the Compensation Committee and the Nominating and Corporate Governance Committee. Each committee has a written charter that addresses, among other matters, the committee’s purposes and policy, composition and organization, duties and responsibilities and meetings. The committee charters are available in the governance section of our Investor Relations website at https://investors.compass.com/overview/default.aspx under the “Governance” tab. Each charter permits the applicable committee, in its discretion, to delegate all or a portion of its duties and responsibilities to a subcommittee or any member of the committee. The Nominating and Governance Committee periodically considers and makes recommendations to the Board of Directors regarding the size, structure and composition of the committees. Based on the most recent review, our Nominating and Corporate Governance Committee and Board of Directors determined that the current size, structure and composition of our principal standing committees remains appropriate. Below is a description of each principal committee of the Board of Directors. 13 COMPASS, INC.

Board and Committee Meetings and Attendance Our Board of Directors typically holds at least four regularly scheduled meetings each year, in addition to special meetings scheduled as appropriate. At each regularly scheduled quarterly Board meeting, a member of each principal Board committee reports on any significant matters addressed by the committee since the last quarterly meeting, and the independent directors have the opportunity to meet in executive session without management or non-independent directors present. The Board of Directors expects that its members will rigorously prepare for, attend and participate in, all Board and committee meetings. Our Board met thirteen times during 2021. Mr. Reffkin, one of the director nominees, who served on the Board of Directors in 2021 attended 100% of all our Board meetings in 2021. Mr. Martell, the other director nominee, joined the Board of Directors on November 23, 2021, attended the meeting that occurred that day which was the last board meeting held in 2021. All directors are expected to attend the Annual Meeting. Role of the Board of Directors in Risk Oversight As any other business, we face a number of risks and a sound risk management framework is critical to our success. Management is responsible for the day-to-day oversight and management of strategic, financial, business and operational, legal and compliance, and cybersecurity and information technology risks, while our Board of Directors, directly and through its committees, is responsible for the overall risk assessment and oversight of our risk management framework, which is designed to identify, assess, and manage risks to which our Company is exposed, as well as to foster a corporate culture of integrity. Our Board of Directors regularly reviews our strategic, business and operational risks in the context of regular discussions with management and reports from the management team at Board meetings. Our Board of Directors also receives regular reports from our principal committees about specific risks that each committee is tasked to oversee. The Audit Committee is responsible for oversight of the Company’s major financial, enterprise, legal, and regulatory compliance risks as well as exposures and risks in other areas as the Audit Committee deems necessary or appropriate from time to time. The Audit Committee also oversees the steps management has taken to monitor or mitigate such risks and exposures, including the Company’s procedures and any related policies with respect to risk assessment and risk management. Additionally, the Audit Committee is also tasked with oversight of the Company’s cybersecurity and other information technology risks, controls and procedures, including the Company’s plan to mitigate cybersecurity risks and respond to data breaches. The Compensation Committee is responsible for oversight of the Company’s major compensation-related risk exposures, as well as the steps management has taken to monitor or mitigate such exposures. The Nominating and Corporate Governance Committee is responsible for oversight of the Company’s programs related to corporate responsibility and sustainability, including environmental, social and corporate governance matters and diversity and inclusion matters. Considerations in Evaluating Director Nominees The Board of Directors is responsible for nominating persons for election to the Board of Directors and for filling vacancies on the Board that may occur between annual meetings of stockholders. The Nominating and Governance Committee has primary responsibility for setting the qualifications as to who can sit on the Board of Directors and is 16 2022 PROXY STATEMENT Toppan Merrill - Compass_ Inc DEF 14A ED | 111292 | 15-Apr-22 00:50 | 22-10332-1.da | Sequence: 11 CHKSUM Content: 21285 Layout: 51328 Graphics: 0 CLEAN JOB: 22-10332-1 CYCLE#;BL#: 9; 0 TRIM: 8.25" x 10.75" AS: New York: 212-620-5600 COLORS: Black, ~note-color 2 GRAPHICS: none V1.5

tasked with identifying individuals who meet those qualifications. The Nominating and Governance Committee also periodically reviews the Board’s size, structure and composition. As part of this process, the Nominating and Governance Committee will consider the size and breadth of our business and the need for Board diversity, and will recommend candidates with the goal of developing an experienced, diverse and highly qualified Board. Director nominees are selected based on criteria such as independence, integrity, diversity (including with respect to race, ethnicity, gender and sexuality), geography, expertise, breadth of experience, knowledge about our business and industry, willingness and ability to devote adequate time and effort to the Board of Directors, ability to contribute to the Board of Directors overall effectiveness and the needs of the Board and its committees. When helpful, the Nominating and Governance Committee may retain outside consultants to assist in identifying director candidates and also will consider advice and recommendations from stockholders, management and others. The Board of Directors does not nominate any person for election or appoint any person to the Board without the prior favorable recommendation of the Nominating and Governance Committee. Board of Directors and Committee Evaluations The Board of Directors and its principal committees perform annual self-evaluations to assess their performance and effectiveness and to identify opportunities for improvement. The 2022 self-evaluation process is currently underway. Corporate Governance Guidelines and Code of Ethics Our Corporate Governance Guidelines reflect the Board’s strong commitment to sound corporate governance practices and to effective policy and decision making at both the Board of Directors and management level, with a view to enhancing long-term value for the Company’s stockholders. The Corporate Governance Guidelines assist the Board of Directors in the exercise of its governance responsibilities and serve as a framework within which the Board of Directors may conduct its business. The Board of Directors also adopted the Compass Code of Ethics (the “Code of Ethics”) and Vendor Code of Ethics. The Code of Ethics serves as a guide to help us answer potential legal and ethical questions that may arise and apply to our employees, officers and members of our Board of Directors. The Vendor Code of Ethics imposes similar requirements on our agents, independent contractors, vendors, suppliers, and other business partners. The Corporate Governance Guidelines, Code of Ethics and Vendor Code of Ethics are available in the governance section of our Investor Relations website at https://investors.compass.com/ overview/default.aspx under the “Governance” tab. Director Compensation The Compensation Committee is responsible for reviewing and making recommendations to the Board of Directors regarding compensation paid to non-employee directors for their Board and committee service. The Compensation Committee reviews the non-employee director compensation policy annually to ensure its competitiveness in relation to the general market and the Company’s peer group. 17 COMPASS, INC.

Related Person Transactions Our Board of Directors adopted a written policy governing the review and approval of related person transactions (the “Related Person Transactions Policy”). The policy applies to any transaction, arrangement or relationship or series of transactions, arrangements or relationships, in which (1) the Company or any of its consolidated subsidiaries were, are or will be a participant and (2) a related person under the policy has a direct or indirect material interest. The policy defines a related person as (i) a person who is, or at any time since the beginning of our last fiscal year was, a director or executive officer of the Company or a nominee to become a director; (ii) a significant stockholder; or (iii) an immediate family member of a director, director nominee, executive officer or significant stockholder (the “Related Parties”). Our Nominating and Corporate Governance Committee has the primary responsibility for reviewing and approving or disapproving related person transactions under our Related Person Transactions Policy. In a situation in which a member of the Nominating and Governance Committee is a related party in the transaction, then the Audit Committee will review the transaction. Under our Related Person Transactions Policy, any transaction we undertake with a Related Party, irrespective of the amounts involved, must be submitted to the General Counsel for his determination of the approval under the policy. The General Counsel will refer to the Nominating and Corporate Governance Committee any Related Party transaction, and any other transaction that he otherwise determines should be considered for evaluation by the Nominating and Corporate Governance Committee consistent with the purpose of the Related Person Transactions Policy. The Nominating and Corporate Governance Committee will be provided with all relevant information, including: (i) the related party’s relationship to Compass and their interest in the transaction; (ii) the material facts of the proposed transaction, including the anticipated aggregate dollar value of the transaction or, in the case of indebtedness, the largest amount of principal outstanding at any time during the current fiscal year plus all amounts of interest payable on it during the fiscal year; (iii) the rationale for the proposed transaction; and (iv) any other relevant information with respect to the proposed transaction. The Nominating and Corporate Governance Committee may consider any relevant information and considerations, including the impact on the director’s independence if the Related Party is a director. Moreover, the Nominating and Corporate Governance Committee may impose such conditions as it deems appropriate on the Company or on the Related Party in connection with approving the proposed transaction. Once the decision is made, the decision, including any conditions imposed on the transaction, will be conveyed to our General Counsel, who then will convey the decision to the appropriate people within the Company. Additionally, the Nominating and Corporate Governance Committee is required to review annually any previously approved or ratified transactions with Related Parties that remain ongoing and that have a remaining term of more than six months. A transaction with a Related Party entered into without pre-approval of the Nominating and Corporate Governance Committee will not be deemed to violate the Related Person Transactions Policy or be invalid or unenforceable, provided that the transaction is brought to the Nominating and Corporate Governance Committee as promptly as reasonably practicable after it is entered into or after it becomes reasonably apparent that the transaction is covered by the Related Person Transactions Policy. 20 2022 PROXY STATEMENT Toppan Merrill - Compass_ Inc DEF 14A ED | 111292 | 15-Apr-22 00:50 | 22-10332-1.da | Sequence: 15 CHKSUM Content: 53586 Layout: 39931 Graphics: 0 CLEAN JOB: 22-10332-1 CYCLE#;BL#: 9; 0 TRIM: 8.25" x 10.75" AS: New York: 212-620-5600 COLORS: Black, ~note-color 2 GRAPHICS: none V1.5

Corporate Responsibility Highlights Human Capital Management and Our Culture At Compass we believe that our long-term success is based on attracting, developing, and retaining a diverse group of employees who espouse our entrepreneurship principles which define our culture: dream big; move fast; learn from reality; be solutions-driven; obsess about opportunity; collaborate without ego; maximize your strengths; and bounce back with passion. It is important to us that Compass is a truly great place to work—a place where our employees feel like they belong, are set up for success and can grow. To further this human capital management strategy, we focus on providing training and development opportunities to promote professional development and advancement within the Company, seek employee feedback regularly through engagement surveys and cultivate a workplace that embraces diversity, equity, and inclusion. Professional Development & Advancement Employee training and development is critical to our Company and we believe that investment in our employees will help us achieve our long-term success. We are committed to providing various training programs and professional development opportunities to our employees so that they can develop critical soft and technical skills and capabilities necessary to excel in their current roles and advance their careers. At Compass we strive to prioritize promoting from within. When possible we look first to our existing employees before soliciting external hires. This priority extends throughout the company up to and including our senior leadership team. For example, in 2021, we promoted Priyanka Singh as our new Chief People Officer. Additionally, in early 2022, two new senior leadership roles were filled from within—Neda Navab became the President, US, Regional Operations and Danielle Wilkie became the President, Customer Success. Employee Engagement We strongly value our employee engagement and it is our culture to seek employee feedback regularly. Since 2017. we have obtained annual employee feedback via online employee engagement surveys and in 2022, we are rolling out new quarterly “pulse” surveys to obtain even more regular feedback from our employees. Through the surveys, we measure how successful we have been in establishing our culture, employee engagement, overall employee job satisfaction and employee work-life balance. We use survey results to improve our employee’s experience, refocus the emphasis we put on various aspects of our employees’ relationship to our Company and improve our employee benefit offerings. Diversity, Equity & Inclusion Cultivating a workplace that embraces diversity, equity, and inclusion is important to us. We do so by embracing diversity and fostering an open environment through our employee-led affinity groups available to all of our employees. We have over 10 employee affinity groups including Black at Compass, Out at Compass, Veterans at Compass, Moms at Compass, Indigenous at Compass and Latinx at Compass. Each of our affinity groups are led by and for employee community members and allies and championed by executive leadership. Our affinity groups provide extraordinary programming for our employees ranging from discussions, panels, volunteer opportunities, and social events. Additionally, we offer special programing during Black History Month, Women’s History Month, AAPI Heritage Month, 22 2022 PROXY STATEMENT Toppan Merrill - Compass_ Inc DEF 14A ED | 111292 | 15-Apr-22 00:50 | 22-10332-1.da | Sequence: 17 CHKSUM Content: 15989 Layout: 62602 Graphics: 0 CLEAN JOB: 22-10332-1 CYCLE#;BL#: 9; 0 TRIM: 8.25" x 10.75" AS: New York: 212-620-5600 COLORS: Black, ~note-color 2 GRAPHICS: none V1.5

LGBTQ+ Pride Month, Latinx Heritage Month and National Native American Heritage Month. To reaffirm our strong commitment to diversity, equity and inclusion, we recently declared Juneteenth a paid company holiday so that our employees can commemorate this day. In 2021, we had our first summer internship program for diverse talent in the product and engineering department where our interns worked alongside our product and engineering team on specific projects and gained practical experience. Our Communities We are committed to serving our local communities. In 2019, we launched Compass Cares, a national philanthropy program focused on causes in the local communities we serve. As we work to help everyone find their place in the world, Compass Cares empowers Compass employees and agents to support meaningful causes where it counts most—in their local communities. Since the inception of the program, our local Compass Cares Community Funds have supported over 3,000 local organizations nationwide, touching tens of thousands of lives. In 2021, Compass Care Community Funds have supported over 800 meaningful causes. Environmental Sustainability Even though our environmental footprint is limited, we are committed to sustainability in our operations. For example, prior to the COVID-19 pandemic, we had many initiatives at our headquarters focusing on minimizing our environmental impact and creating a safe and comfortable working environment. We plan to continue these initiatives when we return back to the office. Our technology platform operates in a cloud-based model, allowing our agents to provide their services remotely without the need to have a physical office. While we continue to have physical offices, we thoughtfully locate them in population centers and they are no larger than needed for our agents to service their clients. We believe that our platform has allowed, and will continue to allow us, to have a smaller physical geographical footprint than would be needed without the platform, thereby minimizing our already limited environmental footprint. 23 COMPASS, INC.

Proposal 2: Ratification of the Appointment of PricewaterhouseCoopers LLP as Our Independent Public Accounting Firm for 2022 Background The Audit Committee, which consists entirely of independent directors, has selected PwC as our independent registered public accounting firm for the fiscal year ending December 31, 2022. We believe that PwC offers services on par with the best in their industry and is sufficiently qualified to conduct their duties as our independent auditor. Additionally, PwC has served as our independent registered public accounting firm since 2014, and we believe continuation of their service would be in the best interest of the Company and our stockholders. Although our governing documents do not require us to submit this matter to stockholders, the Board of Directors believes that asking stockholders to ratify the appointment of PwC is consistent with best practices in corporate governance. In the event that PwC is not ratified by our stockholders, the Audit Committee will consider this outcome of the vote in its selection process in the future. Even if the selection is ratified, the Audit Committee, in its discretion, may select a different independent registered public accounting firm at any time during the year if it determines that such a change would be in the best interests of the Company and our stockholders. Representatives of PwC are expected to be present at the Annual Meeting and they will be given an opportunity to make a statement at the Annual Meeting if they desire to do so and will be available to respond to appropriate questions. Audit Committee Policy on Pre-Approval of Audit and Permissible Non-Audit Services of Independent Registered Public Accounting Firm The Audit Committee has adopted a policy requiring pre-approval of all audit and permissible non-audit related services provided to the Company by the independent registered public accounting firm. Under this policy, the Audit Committee is responsible for reviewing the scope of the services to be provided and pre-approving the fees for these services. These services may include audit services, audit-related services, tax services and other services. What am I voting on and how should I vote? You are being asked to ratify the appointment of PricewaterhouseCoopers LLP (“PwC”) as the Company’s independent registered public accounting firm for the fiscal year ending December 31, 2022.

Proposal 3: Advisory Vote to Approve 2021 Named Executive Officer Compensation (“Say-on-Pay Vote”) Background As required by Section 14A(a)(1) of the Exchange Act, we are providing our stockholders with an opportunity to approve, on an advisory (non-binding) basis, the 2021 compensation of our NEOs, as described in more detail in the “Compensation Discussion and Analysis” and “Executive Compensation Tables” sections of this proxy statement. This proposal, commonly known as a “Say-on-Pay Vote”, gives our stockholders the opportunity to express their views on our NEOs’ compensation. The vote on this proposal is not intended to address any specific item of compensation, but rather the overall compensation of our NEOs and the compensation philosophy, policies and practices described in this proxy statement. The Compensation Committee believes that the executive officers, including the NEOs, were compensated appropriately and in a way that provided proper incentives to them, ensured alignment of their and stockholders’ interests and supported long-term value creation. As you decide how to vote on this proposal, we encourage you to review the “Compensation Discussion and Analysis” and “Executive Compensation Tables” sections of this proxy statement for more information. As an advisory approval, this proposal is not binding upon us or our Board of Directors. However, the Compensation Committee, which is responsible for the design and administration of our executive compensation program, values the opinions of our stockholders expressed through the vote on this proposal. Accordingly, our Board of Directors and Compensation Committee will consider the outcome of this vote in making future compensation decisions for our NEOs and our executive compensation program. Vote Required The approval, on an advisory (non-binding) basis, of the 2021 compensation of our NEOs, requires a majority of the votes cast by the holders of the shares of our common stock present virtually or represented by proxy at the Annual Meeting and entitled to vote thereon. Abstentions and “broker non-votes” will have no effect on the outcome of the vote. What am I voting on and how should I vote? You are being asked to vote “FOR” the following resolution: “RESOLVED, that the stockholders of Compass, Inc. approve, on an advisory (non- binding) basis, the 2021 compensation of the named executive officers, as described in more detail in the “Compensation Discussion and Analysis” and “Executive Compensation Tables” sections of Compass, Inc.’s proxy statement.” The Board of Directors unanimously recommends a vote “FOR” the resolution to approve, on an advisory (non-binding) basis, the 2021 compensation of the named executive officers (“NEOs”). 35 COMPASS, INC.

Proposal 4: Advisory Vote to Approve the Frequency of Future Say-on-Pay Votes Background As required by Section 14A(a)(2) of the Exchange Act, we are providing our stockholders with an opportunity to indicate their preference regarding the frequency with which future Say-on-Pay Votes should occur. There are four choices for voting on this proposal. You can choose whether future Say-on-Pay Votes should occur every “ONE YEAR,” “TWO YEARS,” or “THREE YEARS.” You may also “ABSTAIN” from voting. After considering the benefits and consequences of each alternative, our Board of Directors recommends that Say-on-Pay Votes shall be submitted to the stockholders every ONE YEAR. Our Board of Directors believes that this frequency is appropriate because compensation decisions are made annually and an annual advisory vote will allow our stockholders to provide more frequent and direct input on our overall compensation of our NEOs and our compensation philosophy, policies and practices. As an advisory approval, this proposal is not binding upon us or our Board of Directors. However, our Board of Directors values the opinions of our stockholders expressed through the vote on this proposal. Accordingly, our Board of Directors will consider the outcome of this vote in determining the frequency of future Say-on-Pay Votes. We will announce our decision on the frequency of future Say-on-Pay Votes in a Form 8-K filed with the SEC no later than 150 days after the Annual Meeting. Vote Required The alternative among “ONE YEAR,” “TWO YEARS,” or “THREE YEARS” that receives the highest number of votes cast at the Annual Meeting by stockholders entitled to vote thereon will be deemed to be the frequency preferred by our stockholders. Abstentions and “broker non-votes” will not have any effect on the outcome of this vote. You are being asked to vote on the frequency of future Say-on-Pay Votes. You may specify whether you prefer the vote to occur every one year, two years, or three years or you may abstain from voting. The Board of Directors unanimously recommends a vote for “ONE YEAR” as the frequency of future Say-on-Pay Votes.

Compensation Discussion and Analysis The following compensation discussion and analysis of our executive compensation philosophy, objectives, and design, our compensation-setting process, the components of our executive compensation program, and the decisions made for compensation in respect of 2021 for our NEOs should be read together with the compensation tables and related disclosures set forth below. The discussion in this section contains forward-looking statements that are based on our current considerations and expectations relating to our executive compensation programs and philosophy. As our business and our needs evolve, the actual amount and form of compensation and the compensation programs that we adopt may differ materially from current or planned programs as summarized in this section. Objectives. Our 2021 executive compensation program was designed to achieve the following objectives: l Attract, retain, and motivate talented executive officers whose skills, experience, and performance are critical to achieve our short-term and long-term financial and strategic objectives; l Encourage our executive officers to reinforce our values; l Align compensation incentives with performance and stockholder value; l Reward our executive officers for their experience and performance and motivate them to achieve our long-term strategic goals; and l Ensure that our total compensation is fair, reasonable, and competitive. 2021 NEOs: Robert Reffkin Founder, Chairman, and Chief Executive Officer Kristen Ankerbrandt Chief Financial Officer Greg Hart Chief Product Officer Priyanka Singh Chief People Officer Neda Navab President, United States, Regional Operations Compensation Philosophy, Objectives and Design Philosophy. We compete in highly dynamic and quickly changing real estate and technology markets and believe that in order for us to be successful in attracting and retaining an experienced executive team, we must have a robust executive compensation program that provides proper incentives to our executives while focusing on individual and overall company performance. We believe our executive compensation program will enable us to achieve our short-term and long-term strategic objectives, while creating sustainable long-term value for our stockholders that facilitate and support our growth. 37 COMPASS, INC.

Design. In 2021 and prior to our initial public offering (“IPO”), the components and structure of the compensation we offered to our executive officers varied based on the individual circumstances allowing us to build an executive team committed to execution of our short-term and long-term strategic objectives. Additionally, in determining the total compensation package for each executive officer, our Compensation Committee, with the assistance of its independent compensation consultant, Semler Brossy, considered compensation of executive officers at our peer companies. The total compensation package for our executive officers in 2021 consisted primarily of a combination of base salary, cash bonuses (in the form of sign-on and performance bonuses) and long-term incentives in the form of service-based and performance-based equity awards. Pre-IPO, our executive compensation program was weighted toward equity compensation, consisting of restricted stock units (“RSUs”) and stock options, as well as cash bonuses. In connection with our IPO, we changed our equity compensation structure to primarily grant RSUs and we only grant stock options if required under pre-IPO commitments or in other very limited circumstances. In 2021, we used base salaries to compensate executive officers for their day-to-day responsibilities at levels that we felt were necessary to attract and retain executive talent. However, we believe that placing a strong emphasis on equity compensation and performance cash bonuses linked to achievement of company and individual performance goals aligns with our entrepreneurial spirit and incentivizes our executive officers to maximize stockholder value by pursuing strategic opportunities that advance our mission. We expect that our need to attract and retain executive talent in competition with other leading publicly-traded real estate and technology companies will remain essential to our future success and may become more challenging over time. We regularly evaluate our executive compensation philosophy and program. The Compensation Committee reviews our executive compensation program on an annual basis and seeks to align our executive compensation philosophy and program with those of leading U.S. publicly-traded real estate and technology companies while retaining a necessary measure of flexibility to help us achieve our long-term strategic goals and to account for individual circumstances. As a result, the allocations among specific compensation elements may shift for our executive officers from time to time as we continue to assess the appropriate mix to align with our compensation philosophy but we intend to continue our emphasis on pay-for-performance and long-term incentive compensation. Changes to Executive Compensation Program for 2022. In late 2021 and early 2022, our Compensation Committee, together with its independent compensation consultant, Semler Brossy, reviewed and aligned our executive compensation program with those of leading U.S.-based publicly-traded real estate and technology companies, while retaining a necessary measure of flexibility to address appropriate individual circumstances. The 2022 executive compensation program is based on three principles: provide simple and transparent structure for executive compensation, tie executive compensation to a specific set of company performance metrics and reward individual performance. Specifically, the 2022 compensation program standardizes base salaries for all executive officers and provides for a new short-term incentive program, under which cash performance bonuses will be determined based on Adjusted EBITDA, individual and department results and an internal financial metric calculated by subtracting (i) commissions and other related expense (net of stock-based compensation expense) from (ii) revenue. Additional information about our 2022 executive compensation program, including 2022 performance goals and associated potential payout levels, will be provided in our 2023 proxy statement. 38 2022 PROXY STATEMENT Toppan Merrill - Compass_ Inc DEF 14A ED | 111292 | 15-Apr-22 00:50 | 22-10332-1.fa | Sequence: 4 CHKSUM Content: 62130 Layout: 44813 Graphics: 0 CLEAN JOB: 22-10332-1 CYCLE#;BL#: 9; 0 TRIM: 8.25" x 10.75" AS: New York: 212-620-5600 COLORS: Black, ~note-color 2 GRAPHICS: none V1.5

Components of 2021 Neo Compensation Our 2021 executive compensation program consists primarily of base salaries, short-term cash incentives and long-term equity incentives. In order to promote long-term stockholder value creation and link compensation to our long-term strategic objectives, our primary focus is on long-term equity compensation. A summary of our key compensation components and the rationale for each component is set forth below. Objectives and Category Form of Payment Performance Period Determination Factors l Compensates for day-to-day responsibilities l Based upon each executive’s skills, experience, performance, value in the marketplace and criticality of the role Ongoing Cash Salary l Drives achievement of key corporate performance goals and rewards for annual performance l Based upon each executive’s annual accomplishments and achievement of short-term strategic objectives One year Cash Short-Term Incentive l Encourages executives to achieve long- term strategic objectives and promote long-term stockholder value creation and alignment of executives’ and stockholders’ interests l Based upon each executive’s role and individual contributions they make to achieving long-term strategic objectives Vests quarterly or monthly over four years Performance and service-based Restricted Stock Units (“RSUs”) Long Term Incentive 39 COMPASS, INC.

Base salary. We provide base salary as a fixed source of compensation for our executive officers for their day-to-day responsibilities, allowing them a degree of certainty while having a significant portion of their compensation “at risk” in the form of short-term and long-term incentives, which are contingent on future performance. Our Compensation Committee recognizes the importance of base salaries as an element of compensation that can help attract and retain talented and experienced executive officers. Base salaries for our executive officers, other than our Chief Executive Officer, were established primarily based on individual negotiations with the executive officers when they joined our company. In determining total compensation for our executive officers, we considered compensation opportunities that these executive officers were foregoing from their prior employers, each executive officer’s anticipated role criticality relative to others at our company, and the determination by our Compensation Committee or Board of Directors with input from members of our management, including our Chief Executive Officer, of the essential need to attract and retain these executive officers. Our Compensation Committee reviews base salaries of our executive officers periodically and makes adjustments as deemed appropriate. Our NEOs’ base salary rates as of December 31, 2021 were as follows: 2021 Base Salary NEO ($) Robert Reffkin 400,000 Kristen Ankerbrandt 375,000 Greg Hart 400,000 Priyanka Singh* 350,000 Neda Navab 310,000 * as of July 2021; see section entitled “2021 Summary Compensation Table” for additional information. Short-Term Incentives. In 2021, our executive officers were eligible to earn discretionary cash annual bonuses based on individual and company performance (“performance bonuses”). The amount of the bonus earned and the evaluation of company and individual performance were determined by our Board of Directors for our Chief Executive Officer and by our Compensation Committee, after consultation with our Chief Executive Officer and Chief People Officer, for our other executive officers taking into account individual performance and contributions to our performance. We set target annual bonus amounts for our executive officers at the time they joined our company. These target amounts were determined on an individual basis, based on individual negotiations with each executive officer and taking into consideration factors such as compensation opportunities that the executive officers were foregoing at prior employers, cash bonuses provided to executive officers at our peer companies and role criticality relative to others at our Company. Determinations were made by our Compensation Committee, with input from members of our management, including our Chief Executive Officer. 40 2022 PROXY STATEMENT Toppan Merrill - Compass_ Inc DEF 14A ED | 111292 | 15-Apr-22 00:50 | 22-10332-1.fa | Sequence: 6 CHKSUM Content: 19742 Layout: 29093 Graphics: 0 CLEAN JOB: 22-10332-1 CYCLE#;BL#: 9; 0 TRIM: 8.25" x 10.75" AS: New York: 212-620-5600 COLORS: Black, ~note-color 2 GRAPHICS: none V1.5

Our NEOs’ performance bonuses for the fiscal year ending December 31, 2021 were as follows: 2021 Performance Bonus NEO ($) Robert Reffkin 130,000 Kristen Ankerbrandt 175,000 Greg Hart 200,000 Priyanka Singh 140,548 Neda Navab 291,274 Additionally, as part of our short-term incentive program, from time to time, we provide special cash sign-on and retention bonuses to attract talented and experienced executive officers. We have provided sign-on bonuses based on individual negotiations which reflect, in large part, compensation opportunities that these executive officers were foregoing from their prior employers, the executive officer’s anticipated role criticality relative to others at our company, and the determination by our Compensation Committee, and members of our management, including our Chief Executive Officer, of the essential need to attract and retain these executive officers. For example, Greg Hart, our Chief Product Officer, received a two year cash sign-on bonus in the amount of $1,450,000 paid in 2020 and $2,900,000 paid in 2021, which was partially designed to offset compensation that he forfeited from his previous employer when he joined our company in 2020. Long-Term Incentives. We use equity incentives as a key component of our total compensation package for our executive officers, and the primary vehicle for their long-term incentives. Equity awards are designed to encourage high performance by and long-term tenure for executive officers, thereby aligning executive officers’ interests with the interests of our stockholders. Consistent with our compensation objectives, we believe this approach has allowed us to attract and retain experienced and talented executive officers, aligned our executive officers’ incentives with the long- term interests of our company and our stockholders, and focused our executive officers on achieving our financial and strategic objectives. In determining the form, size, material terms, and frequency of executive equity awards in 2021, our Compensation Committee considered, among other things, the criticality of each executive officer’s role relative to others at our company, company and individual performance, and the remaining unvested equity from the previously granted equity awards, and the need to retain each of these executive officers. For example, Ms. Singh received a sign on equity award of 113,430 RSUs when she joined us in 2021 and a promotion equity award of 43,053 RSUs when she was later promoted to Deputy Chief People Officer. Similarly, Ms. Navab received an equity award of 145,000 RSUs in connection with her assuming the role of President, East Region. 41 COMPASS, INC.

Equity awards granted to our NEOs during the fiscal year ending December 31, 2021 were as follows: 2021 Equity Awards* NEO Type of Award Grant Date (#) Robert Reffkin Performance-based RSU** 1/25/2021 8,611,810 Kristen Ankerbrandt — — — Greg Hart — — — Priyanka Singh Service-based RSU 3/5/2021 113,430 Service-based RSU 12/29/2021 43,053 Neda Navab Service-based RSU 2/10/2021 145,000 * in number of shares underlying each RSU award ** see section entitled “2021 CEO Performance Award” below for additional information 2021 CEO Performance Award. Prior to our IPO, our Compensation Committee, after consultation with its independent compensation consultant, Semler Brossy, and review of Mr. Reffkin’s pre-existing equity awards, including both service- based and performance-based awards, determined that it would be in the best interests of our stockholders that we grant a performance-based equity award with vesting terms that incentivize Mr. Reffkin to execute on our long-term strategic objectives. In January 2021, the Compensation Committee approved a performance-based RSU award of 8,611,810 shares of Class A common stock to Mr. Reffkin with a structure similar to his performance-based award granted in 2020. We refer to this award as the “2021 CEO Performance Award.” The Compensation Committee believed that the structure of the 2021 CEO Performance Award achieves three goals: (i) provides performance-based compensation, (ii) closely aligns interests of the stockholders and Mr. Reffkin in stock value creation and (iii) promotes long-term retention. The 2021 CEO Performance Award is comprised of eight tranches, with each tranche vesting upon achievement of certain pre-established per share stock price targets (the “price per share targets”). The price per share targets were calculated based on the price per share that our stockholders paid for the Series G preferred stock in our last round of pre-IPO fundraising, which was $15.43 per share (the “reference price”) after accounting for the stock split. The achievement of the price per share targets is determined based on the arithmetic average of the volume-weighted average trading price of our Class A common stock measured over any consecutive 30-day period. We refer to this vesting requirement as the “performance-based vesting condition.” 42 2022 PROXY STATEMENT Toppan Merrill - Compass_ Inc DEF 14A ED | 111292 | 15-Apr-22 00:50 | 22-10332-1.fa | Sequence: 8 CHKSUM Content: 54010 Layout: 29093 Graphics: 0 CLEAN JOB: 22-10332-1 CYCLE#;BL#: 9; 0 TRIM: 8.25" x 10.75" AS: New York: 212-620-5600 COLORS: Black, ~note-color 2 GRAPHICS: none V1.5

We refer to this vesting requirement as the “service-based vesting condition.” Once both the performance-based and service-based vesting conditions are met, the RSUs will vest and be settled into shares of Class A common stock. While the shares will be available to Mr. Reffkin immediately after settlement, under the terms of the 2021 CEO Performance Award, he will only be able to sell them after satisfying the 12-month holding period. Accordingly, January 1, 2025 is the earliest day that Mr. Reffkin will be able to recognize any economic value from the 2021 CEO Performance Award (assuming his continuous service and achievement of at least one price per share target prior to January 1, 2024). Additionally, in order for all RSUs to vest and be settled and for Mr. Reffkin to realize the full economic value of the award, all price per share targets must be achieved. Pursuant to the applicable SEC rules, the value of the 2021 CEO Performance Award disclosed in the section entitled “2021 Summary Compensation Table” below is calculated as of the grant date in accordance with Financial Accounting Board Accounting Standards Codification Topic 718 (“ASC 718”) and does not reflect the actual economic value realized by Mr. Reffkin in 2021. It is currently expected that Mr. Reffkin will not receive any additional equity awards until December 31, 2027. 43 COMPASS, INC.

Our Compensation Best Practices The Compensation Committee seeks to ensure sound executive compensation practices to adhere to our philosophy while appropriately managing risk and aligning our compensation programs with long-term stockholder interests. The following summarizes our executive compensation and policies and practices: WHAT WE DO l Maintain an Independent Compensation Committee and Compensation Consultant. Our Compensation Committee is comprised solely of independent directors. Additionally, our Compensation Committee has engaged its own compensation consultant, Semler Brossy, to provide information, analysis, and other advice on executive compensation independent of management. l Annual Executive Compensation Review. Our Compensation Committee conducts an annual review and approval of our compensation strategy, including a review and determination of our compensation peer group used for comparative purposes and a review of our compensation-related risk profile to ensure that our executive compensation programs do not encourage excessive or inappropriate risk-taking and that the level of risk that they do encourage is not reasonably likely to have a material adverse effect on our company. l Pay for Performance. We emphasize a pay-for-performance philosophy, to align the long-term interests of our executive officers with those of our stockholders. A substantial portion of total compensation for our executive officers is “at risk” in the form of cash bonus and equity. The cash bonus is intended to recognize and incentivize achievement of short-term strategic objectives while the equity awards foster achievement of long-term strategic objectives. l Succession Planning. We periodically review the risks associated with our key executive officer positions to ensure adequate succession plans are in place. WHAT WE DO NOT DO l No “Single-Trigger” Change in Control Severance Payments or Benefits. We do not provide “single- trigger” change in control severance payments or benefits to our NEOs. l No Retirement Plans Specific to Executives. We do not offer defined benefit pension plans or any non- qualified deferred compensation plans or arrangements to our NEOs other than the plans and arrangements that are available to all employees. Our NEOs are eligible to participate in our 401(k) Plan on the same basis as our other employees. l No Change in Control Gross Ups. We do not have any agreements that provide reimbursement or gross-ups for excise taxes on payments or benefits received as a result of a change in control. l No Hedging of our Equity Securities. Our insider trading policy prohibits our employees, including our executive officers, from hedging our securities. 44 2022 PROXY STATEMENT Toppan Merrill - Compass_ Inc DEF 14A ED | 111292 | 15-Apr-22 00:50 | 22-10332-1.fa | Sequence: 10 CHKSUM Content: 13363 Layout: 18070 Graphics: 59069 CLEAN JOB: 22-10332-1 CYCLE#;BL#: 9; 0 TRIM: 8.25" x 10.75" AS: New York: 212-620-5600 COLORS: ~note-color 2, Black, PANTONE 318 U GRAPHICS: X_icon_k.eps, Check_Mark_k.eps V1.5

How Our Compensation is Determined Role of management. In setting compensation, our Chief Executive Officer and Chief People Officer work closely with the independent compensation consultant, Semler Brossy, and advise the Compensation Committee on our executive officers’ compensation. Their activities include reviewing and recommending salary, equity awards and bonuses, and other compensation, recommending performance goals and objectives, and negotiating new hire packages and executive agreements. Additionally, our management gathers and reviews market and operating data prior to making their recommendations to the Compensation Committee. From time to time, members of our management, including our Chief Executive Officer and Chief People Officer, attend meetings (or portions of meetings) of our Compensation Committee to present information and answer questions. Role of our Compensation Committee. Our Compensation Committee with appropriate input from other members of our Board of Directors, and members of our management, including our Chief Executive Officer and Chief People Officer, has been responsible for generally overseeing the determination of the individual and company goals and objectives applicable to the compensation of our executive officers and the activities of our executive compensation program, including making recommendations as to the form and amount of compensation to be paid or awarded to all of our executive officers (including our Chief Executive Officer), and approving the form and amount of such compensation as well as entering into offer letters with all of our executive officers (other than our Chief Executive Officer, whose compensation is determined and approved by the full Board of Directors upon the Compensation Committee’s recommendation). Additionally, our Compensation Committee has oversight of decisions regarding specific equity-based compensation plans, programs, and grants, as well as cash-based compensation plans and agreements for our executive officers. Our Compensation Committee considers a combination of the following factors when reviewing and approving executive compensation: l individual negotiations with executive officers, particularly in connection with their initial compensation package and changes to compensation packages, including past or future compensation opportunities; Evaluate and recommend to the Compensation Committee our executive officers’ (other than the Chief Executive Officer) compensation Role of Management Oversee (i) the determination of the individual and Company goals and objectives applicable to the compensation of our executive officers and (ii) the activities of our executive compensation program, including making recommendations as to the form and amount of compensation to be paid or awarded to all of our executive officers (including our Chief Executive Officer), and approving the form and amount of such compensation as well as entering into offer letters with all of our executive officers other than our Chief Executive Officer, whose compensation is determined by the full Board of Directors upon the Compensation Committee’s recommendation Role of Compensation Committee Advise the Compensation Committee with respect to (i) executive compensation, (ii) negotiation of new hire packages, (iii) trends in executive compensation market, and (iv) design and operation of the executive compensation program. Role of Compensation Consultant Allows for benchmarking executive officer compensation against our peer group and provides a meaningful input to our compensation policies and practices in order for us to remain competitive Role of Peer Group 45 COMPASS, INC. Toppan Merrill - Compass_ Inc DEF 14A ED | 111292 | 15-Apr-22 00:50 | 22-10332-1.fa | Sequence: 11 CHKSUM Content: 38740 Layout: 52805 Graphics: 0 CLEAN JOB: 22-10332-1 CYCLE#;BL#: 9; 0 TRIM: 8.25" x 10.75" AS: New York: 212-620-5600 COLORS: Black, ~note-color 2 GRAPHICS: none V1.5

l company and individual performance, as we believe this motivates our executive officers to achieve our financial and strategic objectives and aligns their interests with those of our stockholders; l criticality of each executive officer’s role to us; and l recommendations of members of management, including our Chief Executive Officer and Chief People Officer. Role of compensation consultants. The Compensation Committee has retained Semler Brossy as its independent executive compensation consulting firm. Semler Brossy advises the Compensation Committee with respect to executive compensation, negotiation of new hire packages, trends in the executive compensation market, and design and operation of the executive compensation program. Semler Brossy reports directly to the Compensation Committee, although may meet with members of management for purposes of gathering information on proposals that management may make to the Compensation Committee. The Compensation Committee has considered the independence of Semler Brossy, consistent with the requirements of NYSE, and has determined that Semler Brossy is independent. Semler Brossy does not provide any services to us other than the services provided to the Compensation Committee. Role of peer group. Periodically, our Compensation Committee reviews the selection of companies in our peer group for purposes of benchmarking executive officer compensation programs. While our Compensation Committee does not establish compensation levels solely based on a review of competitive data, it believes such data is a meaningful input to our compensation policies and practices in order to attract and retain qualified executive officers. Our compensation peer group for 2021 was comprised of the below real estate and technology companies: 2021 Peer Group Black Knight Envestnet Redfin Blackbaud Euronet Worldwide Slack Technologies CDK Global Guidewire Software SS&C Technologies Holdings Datadog GoDaddy Yelp Dropbox Palo Alto Networks Zillow Group Elastic N.V. RealPage Risk Assessment of Compensation Programs. Our management team and the Compensation Committee each play a role in evaluating and mitigating any risk that may exist relating to our compensation plans, practices and policies for all employees, including our NEOs. Semler Brossy, on behalf of the Compensation Committee, performs an assessment, in conjunction with management, of our compensation plans and practices to determine whether our compensation programs create risks that are reasonably likely to have a material adverse effect on our company. Other Compensation Practices and Policies Offer Letters and Severance and Change in Control Arrangements. The terms and conditions of employment for each of our NEOs are set forth in compensation and offer letters. For a summary of the material terms and conditions of these executive agreements, see the section entitled “—Offer Letters” below. For a summary of the material terms and conditions of the severance and change in control arrangements in effect as of December 31, 2021, see the section entitled “—Potential Payments upon Termination or Change in Control” below. Welfare and other benefits. We provide health, dental, vision, life, and disability insurance benefits to our executive officers, on the same terms and conditions as provided to all other eligible U.S. employees. Our executive officers may also participate in our broad-based 401(k) plan, which currently does not include a company match or discretionary contribution. We believe these benefits are consistent with the broad-based employee benefits provided at the companies with whom we compete for talent and therefore are important for attracting and retaining talented and experienced executive officers. 46 2022 PROXY STATEMENT Toppan Merrill - Compass_ Inc DEF 14A ED | 111292 | 15-Apr-22 00:50 | 22-10332-1.fa | Sequence: 12 CHKSUM Content: 8471 Layout: 63770 Graphics: 0 CLEAN JOB: 22-10332-1 CYCLE#;BL#: 9; 0 TRIM: 8.25" x 10.75" AS: New York: 212-620-5600 COLORS: Black, ~note-color 2 GRAPHICS: none V1.5

In addition to the employee benefits described above, we have provided certain of our NEOs with reimbursement of legal expenses and certain fees for a regulatory filing made pursuant to the Hart-Scott-Rodino Antitrust Improvements Act of 1976 (“HSR filing fee”). We believe that the benefits and perquisites described above are consistent with our overall executive compensation program, enable us to attract and retain talented and experienced executive officers, and provide competitive compensation packages to our NEOs. We detail the values of legal expenses and HSR filing fee reimbursement in the section entitled “2021 Summary Compensation Table”. Our Compensation Committee periodically reviews the levels of perquisites and other personal benefits provided to our NEOs. Based on these periodic reviews, perquisites may be awarded or adjusted on an individual basis. Hedging prohibitions and pledging policies. Our insider trading policy, which prohibits, among other things, our employees, including executive officers, and directors, from making short sales and engaging in hedging or monetization transactions involving our securities, whether such securities are granted as compensation or are held, directly or indirectly, by the employee or director. In addition, our insider trading policy prohibits our employees, including executive officers, and directors from pledging our securities as collateral absent previous approval by our general counsel, which shall only be granted in accordance with our pledging guidelines. Our pledging guidelines prohibit pledges of our securities as collateral for “purpose” based margin loans and restrict pledges for other loans. Under our pledging guidelines, our general counsel is allowed to approve pledges of our securities by executive officers only when a loan does not exceed $20 million and pledged securities do not exceed 20% of all outstanding securities held by the pledging executive officer. Exchange Act Rule 10b5-1 Plans. Our executive officers and non-employee directors may only transact in our securities pursuant to written plans, known as “Rule 10b5-1 plans,” in which they contract with a broker to buy or sell shares of our Class A common stock on a periodic basis. Under a Rule 10b5-1 plan, a broker executes trades pursuant to parameters established by the executive officer or non-employee director when entering into the plan, without further direction from them. Accelerated Vesting. We have approved accelerated vesting provisions for certain RSU and stock option grants to certain executive officers upon an involuntary termination of those executive officers’ employment in connection with a change in control (each “involuntary termination” and “change in control” as defined in the section entitled “Potential Payments Upon Termination or Change in Control”). We believe these accelerated vesting provisions reflect current market practices, based on the collective knowledge and experiences of our Compensation Committee members and of its compensation consultants, Semler Brossy, and allow us to attract and retain talented and experienced executive officers. We also believe that these accelerated vesting provisions will allow our executive officers, including our NEOs, to focus their attention on the business operations of our company in the face of the potentially disruptive impact of a rumored or actual change in control transaction, to assess takeover bids objectively without regard to the potential impact on their own job security, and to allow for a smooth transition in the event of a Change in Control. Additional information regarding accelerated vesting in connection with a Change in Control is discussed below in the section entitled “Potential Payments Upon Termination or Change in Control.” Tax and Accounting Considerations. Section 162(m) of the Internal Revenue Code of 1986, as amended (the “Code”) generally disallows public companies a tax deduction for federal income tax purposes of remuneration in excess of $1 million paid to their principal executive officer, principal financial officer, and certain other current and former executive officers. Recent changes to Section 162(m) in connection with the passage of the Tax Cuts and Jobs Act of 2017 repealed exceptions to the deductibility limit that were previously available for “qualified performance-based compensation,” including stock option grants, effective for taxable years after December 31, 2017. As a result, any compensation paid to certain of our executive officers in excess of $1 million will be non-deductible unless it qualifies for transition relief afforded to compensation payable pursuant to certain binding arrangements in effect on November 2, 2017. The Compensation Committee has not in past years taken the deductibility limit imposed by Section 162(m) into 47 COMPASS, INC. Toppan Merrill - Compass_ Inc DEF 14A ED | 111292 | 15-Apr-22 00:50 | 22-10332-1.fa | Sequence: 13 CHKSUM Content: 52399 Layout: 63236 Graphics: 0 CLEAN JOB: 22-10332-1 CYCLE#;BL#: 9; 0 TRIM: 8.25" x 10.75" AS: New York: 212-620-5600 COLORS: Black, ~note-color 2 GRAPHICS: none V1.5

consideration in setting compensation for our executive officers. The Compensation Committee will continue to monitor the issue of deductibility of executive compensation and make adjustments to our executive compensation program to maximize the deductibility of our executive compensation to the extent that it believes such result is consistent with the objectives of individual compensation elements and the best interests of us and our stockholders. Sections 280G and 4999 of the Code provide that executive officers who hold significant equity interests and certain other service providers may be subject to significant additional taxes if they receive payments or benefits in connection with a change in control of the company that exceeds certain prescribed limits, and that the company or a successor may forfeit a deduction on the amounts subject to this additional tax. None of our executive officers, including our NEOs, are entitled to “gross-up” or other reimbursement payment for any tax liability that the executive officer might owe as a result of the application of Sections 280G or 4999. Our Compensation Committee considers accounting implications when designing compensation plans and arrangements for our executive officers and other employees. Chief among these is FASB ASC Topic 718 (“ASC 718”), the standard which governs the accounting treatment of certain stock-based compensation. Among other things, ASC 718 requires us to record a compensation expense in our income statement for all equity awards granted to our executive officers and other employees. This compensation expense is based on the grant date “fair value” of the equity award and, in most cases, will be recognized ratably over the award’s requisite service period (which, generally, will correspond to the award’s vesting schedule). This compensation expense is also reported in the compensation tables set forth in this proxy statement, even though recipients may never realize any value from their equity awards. 48 2022 PROXY STATEMENT Toppan Merrill - Compass_ Inc DEF 14A ED | 111292 | 15-Apr-22 00:50 | 22-10332-1.fa | Sequence: 14 CHKSUM Content: 32907 Layout: 47804 Graphics: 0 CLEAN JOB: 22-10332-1 CYCLE#;BL#: 9; 0 TRIM: 8.25" x 10.75" AS: New York: 212-620-5600 COLORS: ~note-color 2, Black GRAPHICS: none V1.5

All stock options referenced in this table are subject to early exercise provisions. 2.) Amounts are calculated by multiplying the number of shares shown in the table by $9.09, the closing per share price of our Class A common stock as of December 31, 2021. 3.) On March 31, 2021 in connection with our IPO, shares of Class A common stock subject to the stock award were converted into Class C common stock, with the vesting conditions remaining in place. The amount of shares reflected in this table is shares of Class C common stock. The service-based vesting condition provides that 1/48th of the shares of Class C common stock under the stock award vests monthly, with 100% of the total shares vesting on June 21, 2022, subject to Mr. Reffkin remaining in continuous service with us through each vesting date. 4.) The service-based vesting condition provides that 1/48th of the shares of Class A common stock under the RSU award vests monthly, with 100% of the total shares vesting on December 25, 2023, subject to Mr. Reffkin remaining in continuous service with us through each vesting date. 5.) RSU award vests upon the satisfaction of both (i) a service-based vesting condition and (ii) the achievement of performance-based vesting conditions. The service-based vesting condition requires Mr. Reffkin to remain in continuous service with us through January 1, 2024 and the performance-based vesting conditions provides that 12.5% of the shares subject to the RSU will vest subject to the achievement of a market price per share of $23.14 per share of our Class A common stock following our IPO or 150% of the price of $15.43, or the “reference price.” An additional 12.5% of the shares subject to the RSU will vest upon the achievement of a market price per share of our Class A common stock at each of 200%, 250%, 300%, 350%, 400%, 450% and 500% of the reference price. The price per share of our Class A common stock will be based on the arithmetic average of the volume-weighted average trading price of our Class A common stock on any 30 trading-day- window period beginning on October 28, 2021 (210th day after our IPO). 6.) The shares subject to the stock option are fully vested. 7.) Represents the exercise price of the stock options as of November 28, 2020 pursuant to an adjustment mechanism in Ms. Ankerbrandt’s stock option agreement, dated March 28, 2019. Upon the second anniversary of Ms. Ankerbrandt’s continued service with us, the exercise price of the stock options increased from $5.16 to $9.48 in accordance with the terms of the stock option agreement. 8.) The service-based vesting condition provides that 4.1667% of the shares of Class A common stock underlying the stock options vests monthly, with 100% of the total shares vesting on November 26, 2022, subject to Ms. Ankerbrandt remaining in continuous service through each vesting date. 9.)

Options Exercised and Stock Vested in 2021 The following table sets forth information regarding options exercised and stock awards vested for the NEOs during the year ended December 31, 2021.

Reflects the difference between the exercise price and the fair market value of the underlying stock on the date of exercise, multiplied by the number of shares acquired. 2.) Represents the number of RSUs vested in 2021. Shares underlying RSUs are released to RSU holders at the beginning of each month with respect to RSUs that vested in the prior month. As a result, shares underlying RSUs vested in December 2021 reflected in this column were not released to our NEOs until January 2022. Prior to December 2020, we granted RSU awards that vested based upon the satisfaction of both a service-based condition and a liquidity event-based condition. The service-based vesting condition for these awards is generally satisfied over four years. The liquidity event-based vesting condition is satisfied on the occurrence of a qualifying event and was satisfied at IPO. Accordingly, all RSUs that satisfied the service- based vesting condition prior to the IPO became fully vested at the time of the IPO. Additionally, all RSU awards granted prior to the IPO included a provision that required us to settle all fully vested RSUs within a few months of our IPO. As a result, we settled all fully vested RSUs in October of 2021, resulting in a large number of shares being acquired by certain of our NEOs in 2021. The below table illustrates how the RSUs granted to our NEOs were earned with respect to the service-based vesting during the years ended December 31, 2019, 2020 and 2021, assuming that the liquidity-event based condition was satisfied in 2019 and RSUs were settled in the same year in which they vested. We believe this table clarifies that the large number of shares acquired by our NEOs in 2021 pursuant to the vesting and settlement of RSUs represents compensation earned in respect of multiple years of service.

Potential Payments Upon Termination or Change in Control In hiring several of our NEOs pre-IPO, we recognized that many of our desired candidates were leaving the security of employment with companies where they had existing severance and change in control compensation benefits. Accordingly, we sought to develop compensation packages that could attract talented and experienced executive officers while being sensitive to the need to integrate new executive officers into our existing executive compensation structure. To achieve this balance, we approved severance benefits for certain NEOs in the event of their involuntary terminations of employment, including in connection with a change in control. We believe that these agreements encourage our executive officers to focus their attention on the business operations of our company in the face of the potentially disruptive impact of a rumored or actual change in control transaction, to assess takeover bids objectively without regard to the potential impact on their own job security and to allow for a smooth transition in the event of a change in control. We believe the size and terms of these benefits we provided appropriately balance the costs and benefits to our stockholders. We also believe these benefits were consistent with the benefits offered by companies with whom we compete for talent, and accordingly allow us to recruit and retain talented and experienced executive officers. The following table and the narrative for each column set forth our payment obligations pursuant to the compensation arrangements for each of our NEOs, under the circumstances described in the table and narrative, assuming that their employment was terminated or a change in control occurred on December 31, 2021.

Additionally, by following the instructions in the Notice, you may request to receive proxy materials in printed form by mail or electronically by email on an ongoing basis. We believe that these rules allow us to provide our stockholders with the information they need while lowering the costs of delivery and reducing the environmental impact of the Annual Meeting. Why did I receive a Notice instead of a full set of proxy materials? Unless you have requested that we provide a copy of our proxy materials to you by mail or email, we are providing only the Notice to you by mail or email. The Notice will instruct you as to how you may access and review the proxy materials on the Internet. The Notice will also instruct you as to how you may access your proxy card to vote over the Internet. If you received the Notice by mail or email and would like to receive a paper copy of our proxy materials, free of charge, please follow the instructions included in the Notice. This proxy statement is dated April 15, 2022 and distribution of the Notice to stockholders is scheduled to begin on or about April 15, 2022. We have adopted this procedure pursuant to rules adopted by the SEC in order to conserve natural resources and reduce our costs of printing and distributing the proxy materials, while providing a convenient method for stockholders to access the materials and vote. What does it mean if I received more than one Notice or proxy card? If you receive more than one Notice or proxy card, your shares are registered in more than one name or are registered in different accounts. To make certain all of your shares are voted, please follow the instructions included on each Notice or proxy card and provide voting instructions for each Notice or proxy card by telephone, through the Internet, or by mail. If you requested or received paper proxy materials and you intend to vote by mail, please complete, sign, and return each proxy card you received to ensure that all of your shares are voted. 58 2022 PROXY STATEMENT Toppan Merrill - Compass_ Inc DEF 14A ED | 111292 | 15-Apr-22 00:50 | 22-10332-1.ha | Sequence: 1 CHKSUM Content: 49671 Layout: 1664 Graphics: 0 CLEAN JOB: 22-10332-1 CYCLE#;BL#: 9; 0 TRIM: 8.25" x 10.75" AS: New York: 212-620-5600 COLORS: Black, ~note-color 2 GRAPHICS: none V1.5

I share an address with another stockholder, and we received only one paper copy of the proxy materials. How may I obtain an additional copy of the proxy materials? The SEC has adopted rules that permit companies and intermediaries (e.g., brokers) to satisfy the delivery requirements for the proxy materials or other annual meeting materials with respect to two or more stockholders sharing the same address by delivering a single set of proxy materials or other annual meeting materials addressed to those stockholders. This process, which is commonly referred to as “householding,” is intended to provide extra convenience for stockholders and reduce costs. We and a number of brokers with account holders who are our stockholders will be householding our proxy materials. We will deliver a single set of proxy materials to multiple stockholders sharing an address unless contrary instructions have been received from the affected stockholders. Stockholders who participate in householding will continue to be able to access and receive separate proxy cards. If, at any time, you no longer wish to participate in householding and would prefer to receive a separate set of proxy materials, or if you are receiving multiple sets of proxy materials and would like to receive only one, please notify your broker, bank or other nominee if you are a beneficial stockholder or notify us if you are a registered stockholder. Registered stockholders can notify us by sending a written request to Compass, Inc., c/o Corporate Secretary, 90 5th Ave 3rd floor, New York, New York 10011 or by email at corporatesecretary@compass.com, and we will promptly deliver any additional proxy materials requested.

value $0.00001 per share, were outstanding. Only holders of record of our common stock as of the record date will be entitled to notice to vote. What is the difference between holding shares as a stockholder of record and as a beneficial owner? Stockholders of Record (shares registered in your name). If your shares are registered directly in your name with our transfer agent, Computershare Shareowner Services LLC, you are considered the stockholder of record with respect to those shares. As the stockholder of record, you have the right to grant your voting proxy directly to Compass or to a third party, or to vote your shares during the Annual Meeting. Beneficial Owners (shares registered in the name of your broker, bank or other nominee). If your shares are held in a brokerage account or by a bank or other holder of record (commonly referred to as holding shares in “street name”), you are considered the “beneficial owner” of those shares. As the beneficial owner, you have the right to direct your broker, bank or other holder of record how to vote your shares during our Annual Meeting. How do I vote before the Annual Meeting and what is the voting deadline? You may vote before the Annual Meeting through any of the following methods: www.viewproxy.com/COMPASS/2022 VIA THE INTERNET Call 1 (866) 804-9616 (if you are a registered record holder) BY TELEPHONE Complete, date, and sign your proxy card (if you are a record holder) or voting instruction form (if you are a beneficial holder) and return it in the postage-paid envelope BY MAIL Internet and telephone voting are available 24 hours a day until 11:59 p.m. Eastern Time on Wednesday, June 1, 2022.

How do I vote at the Annual Meeting? The Annual Meeting will be held virtually. To participate in the Annual Meeting, you will first need to register at www.viewproxy.com/COMPASS/2022.Your registration must be received by 11:59 p.m. Eastern Time on May 30, 2022. At the time of the registration you will be provided a unique join link and password that you will need to use to access the Annual Meeting at the time of the meeting. Whether you are a stockholder of record or a beneficial stockholder, you may vote your shares electronically during the Annual Meeting. Even if you plan to participate in the Annual Meeting, we recommend that you also vote by proxy as described above so that your vote will be counted if you later decide not to participate in the Annual Meeting. A list of registered stockholders entitled to vote at the Annual Meeting will be available for inspection by stockholders during the Annual Meeting for any legally valid purpose related to the Annual Meeting. Can I change my vote or revoke my proxy? Stockholders of Record (shares registered in your name). If you are the stockholder of record, you may change your vote before the Annual Meeting by submitting a later-dated proxy through any of the methods described under question “How do I vote before the Annual Meeting and what is the voting deadline?” above, which will automatically revoke the earlier proxy. You do not need to deliver the later-dated proxy using the same method as the original proxy. You can also revoke your proxy by delivering a written notice to our Corporate Secretary stating that you are revoking your proxy. This revocation is valid only if we receive your notice before the Annual Meeting. Beneficial Owners (shares registered in the name of your broker, bank or other nominee). If you are a beneficial holder, please contact your broker or nominee for the procedures on revoking your proxy or changing your vote before the meeting. Both stockholders of record and beneficial holders may change their vote by attending the Annual Meeting and voting at the meeting. However, your attendance at the Annual Meeting, alone, will not revoke your proxy. What is the effect of giving a proxy? All proxies will be voted in accordance with the instructions specified on the signed proxy card. If you sign a physical proxy card and return it without instructions as to how your shares should be voted on a particular proposal at the Annual Meeting, your shares will be voted in accordance with the recommendations of our Board of Directors. What if I do not specify how my shares are to be voted? If you do not vote and you hold your shares in street name, and your broker does not have discretionary power to vote your shares, your shares may constitute “broker non-votes” (as described below) and will not be counted in determining the number of shares necessary for approval of the proposals. However, broker non-votes will be counted for the purpose of establishing a quorum for the Annual Meeting. What are the effects of abstentions and broker non-votes? A broker non-vote occurs when shares held by a broker are not voted with respect to a particular proposal because the broker does not have discretionary authority to vote on the matter and has not received voting instructions from its clients. If your broker holds your shares in its name and you do not instruct your broker how to vote, your broker will only have discretion to vote your shares on “routine” matters. Where a proposal is not “routine,” a broker who has not received instructions from its clients does not have discretion to vote its clients’ uninstructed shares on that proposal. At our Annual Meeting, only the ratification of the appointment of our independent registered public accounting firm 61 COMPASS, INC.

62 2022 PROXY STATEMENT (Proposal 2) is considered a routine matter. All other proposals are considered “non-routine,” and your broker will not have discretion to vote on these proposals. Broker non-votes and abstentions by stockholders from voting (including brokers holding their clients’ shares of record who cause abstentions to be recorded) will be counted towards determining whether or not a quorum is present. However, because broker non-votes and abstentions are not voted affirmatively or negatively, they will have no effect on the approval of any of the proposals. What is a quorum? The holders of a majority of the voting power of the shares of our common stock entitled to vote at the Annual Meeting as of the record date must be present at the Annual Meeting in order to hold the Annual Meeting and conduct business. This presence is called a quorum. Your shares are counted as present at the Annual Meeting if you are present and vote electronically at the Annual Meeting or if you have properly submitted a proxy. How are proxies solicited for the Annual Meeting and who is paying for such solicitation? The accompanying proxy is solicited by and on behalf of our Board of Directors, whose Notice of the Annual Meeting is attached to this proxy statement, and the entire cost of such solicitation will be borne by us. In addition to the use of the mails, proxies may be solicited by telephone and email by directors, officers and our other employees, who will not be specially compensated for these services. We will also request that brokers, nominees, custodians and other fiduciaries forward soliciting materials to the beneficial owners of shares held of record by such brokers, nominees, custodians and other fiduciaries. We will reimburse such persons for their reasonable expenses in connection therewith. Certain information contained in this proxy statement relating to the occupations and security holdings of our directors and officers is based upon information received from the individual directors and officers. Is my vote confidential? Yes. Proxy instructions, ballots, and voting tabulations that identify individual stockholders are handled in a manner that protects your voting privacy. Your vote will not be disclosed, either within the Company or to third parties, except as necessary (i) to meet applicable legal requirements, (ii) to allow for tabulation and certification of the vote, and (iii) to facilitate successful proxy solicitation by the Board of Directors. How can I find out the results of the voting at the Annual Meeting? We will announce preliminary voting results at the Annual Meeting and publish final results on a Current Report on Form 8-K that we expect to file with the SEC within four business days after the Annual Meeting. Other Information What is the deadline to propose actions for consideration at next year’s annual meeting of stockholders or to nominate individuals to serve as directors? You may present proposals for action at a future meeting or submit nominations for election of directors only if you comply with the requirements of the rules established by the SEC and our amended and restated bylaws, as applicable.
