&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**1.** Election of seven directors to serve until the next annual meeting and until their successors are elected and qualified;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**2.** Ratification of the Audit Committee's appointment of Ernst & Young LLP to act as the independent registered public accounting firm for the fiscal year ending December 31, 2023;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**3.** Advisory vote to approve the compensation of Sunstone's Named Executive Officers, as set forth in the proxy statement for Sunstone's Annual Meeting ("Say-on-Pay Vote");

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**4.** Advisory vote to approve the frequency of holding f uture Say-on-Pay Votes; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**5.** Transaction of other business as may properly come before the Annual Meeting, including any motion to adjourn to a later date to permit further solicitation of proxies, if necessary, or before any adjournment or postponement thereof.

Only stockholders of record of shares of Sunstone common stock, par value $0.01 per share, at the close of business on March 6, 2023 are entitled to notice of and to vote at the Annual Meeting or any adjournment or postponement of the meeting.

Whether you own a few or many shares and whether or not you plan to attend the Annual Meeting, it is important that your shares be voted on matters that come before the meeting. You can ensure that your shares are voted at the meeting by completing, signing, dating and returning the enclosed proxy card in the envelope provided or, if you own shares through a bank or broker that provides for voting by telephone or over the Internet, by submitting your authorization to vote by telephone or over the Internet in accordance with your bank's or broker's instructions. If your proxy card is signed and returned without specifying your choices, your shares will be voted on each proposal in accordance with our Board of Directors' recommendations.

We would like to take this opportunity to thank you for your support of Sunstone. We believe that our continued refinement of our compensation and corporate governance practices, coupled with our commitment to building long–- term value, positions Sunstone for a promising future. We continue to focus on improvements to our corporate compensation and governance practices, as reflected by the following previously implemented initiatives: Proxy Access; Director Holdover Resignation Guidelines; Limitations on Stockholder Rights Plans; Right of Stockholders to Amend Company Bylaws; Restrictions on Classifying Directors; Anti-Hedging and Pledging policies; Clawback Policy; Double-Trigger accelerated vesting; a Pay-For-Performance structure that is aligned with both our stockholders and the expansion of Environmental, Social and Governance initiatives; and on-going Director refreshment and commitment to diversity.

Again, we thank you for your continued support and look forward to a promising future.

By Order of the Board of Directors

PROXY SUMMARY

### OUR COMPENSATION PRACTICES
*Objectives*. We seek to attract, motivate and retain our Named Executive Officers ("NEOs") through competitive compensation arrangements that we believe, within appropriate risk parameters, provide strong financial incentives for the NEOs to maximize stockholder value. Our 2022 NEOs included Messrs. Giglia, Reyes, Springer, Klein and Ostapovicz (the "Current NEOs"). In addition, per SEC rules, our former Interim CEO and former Executive Chairman, Douglas M. Pasquale was also an NEO for 2022. In order to achieve our objectives and mitigate compensation related risks to our stockholders, we utilize the following practices:

---

| | |
|:---|:---|
| **WHAT WE DO** | **WHAT WE DO NOT DO** |
| &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;✔ **WE PAY FOR PERFORMANCE**<br>Our executive compensation program is weighted towards performance-based at-risk compensation, rather than fixed compensation. Specifically, the at-risk portion of our executive compensation program is designed to reward performance relative to financial, stockholder return and other metrics that we believe best align management with stockholder interests.<br>✔ **WE TIE OBJECTIVES TO CORPORATE STRATEGY**<br>A portion of our NEOs' individual objectives are tied to advancing the Company's strategy of owning Long-Term Relevant Real Estate® as well as the achievement of Environmental, Social and Governance ("ESG") initiatives.<br>✔ **WE HAVE A COMPENSATION RECOVERY POLICY ("CLAWBACK POLICY")**<br>Each of our NEOs is subject to a compensation recovery policy that provides the Board the ability to recover portions of the employee's incentive compensation following an accounting restatement due to fraudulent, willful or grossly negligent misconduct.<br>✔ **WE REQUIRE OUR CEO AND OTHER NEOS TO HAVE A MEANINGFUL OWNERSHIP INTEREST IN THE COMPANY**<br>Our executive officer stock ownership policy requires that on or before January 1 of the year following the fourth anniversary of the appointment to such position the CEO or President, Executive Vice Presidents and Senior Vice Presidents who are considered executive officers will own and retain shares of the Company's common stock having a value equal to at least six times, three times and two times his or her annual base salary, respectively.<br>✔ **WE HOLD AN ANNUAL SAY-ON-PAY VOTE**<br>We conduct an annual Say-On-Pay advisory vote to solicit our stockholders' view on our compensation programs.<br>✔ **WE DESIGN COMPENSATION TO MITIGATE EXCESSIVE RISK TAKING**<br>Our Compensation Committee regularly reviews the Company's compensation plans and programs to ensure they are designed to create and maintain stockholder value and avoid encouraging excessive risk-taking.<br>✔ **WE SOLICIT INDEPENDENT COMPENSATION ADVICE**<br>Our Compensation Committee retains Ferguson Partners Consulting ("FPC"), an independent compensation consultant, for purposes of advising and consulting with respect to the compensation of our NEOs. | &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;✘ **WE DO NOT PROVIDE GUARANTEED INCENTIVE COMPENSATION**<br>There are no minimum payout levels on either our annual incentive bonus plan or our equity incentive award plan. A material portion of our equity incentive award plan is tied to achievement of Relative Total Stockholder Return ("RSR") objectives. <br>✘ **WE DO NOT PAY "GROSS UPS" FOR CHANGE IN CONTROL OR SEVERANCE PAYMENTS**<br>We do not provide excise or other tax "gross up" payments in connection with any change in control or severance payment made to an NEO.<br>✘ **WE DO NOT PROVIDE "SINGLE TRIGGER" BENEFITS UPON A CHANGE IN CONTROL**<br>The Employment Agreements (as defined below) with our NEOs require a "double trigger" (requiring both a change in control and qualifying termination of employment) to receive cash or equity payments or vesting in connection with a change in control.<br>✘ **WE DO NOT PAY DIVIDEND EQUIVALENTS ON PERFORMANCE-BASED RESTRICTED STOCK UNITS UNLESS THE AWARDS ACTUALLY VEST**<br>Our NEOs only receive dividend equivalent payments on performance-based restricted stock unit awards to the extent the award vests.<br>✘ **WE DO NOT ALLOW HEDGING OR PLEDGING OF COMPANY STOCK BY EXECUTIVE OFFICERS AND DIRECTORS**<br>Our executive officers and directors are prohibited from engaging in pledging our stock or in hedging transactions designed to offset decreases in the market value of our stock. |

**Improved the quality of our portfolio and increased concentration of Long-Term Relevant Real Estate®.** 

● We acquired The Confidante Miami Beach for an acquisition price of $232 million. We will invest approximately $60 million to reposition the hotel under Hyatt's luxury lifestyle Andaz Brand. We expect the renovation to be completed in 2024, at which time the hotel will debut as the Andaz Miami Beach. Upon completion of the renovation, we expect the hotel to generate an 8% to 9% stabilized net operating income yield on the total investment in the hotel. We also acquired the remaining 25% interest in the 1,190-room Hilton San Diego Bayfront for an implied total transaction value of $157 million. The well-located hotel is a market-leading property in a premiere convention and resort destination. The purchase price represents a highly attractive 11.9x multiple on the hotel's 2022 earnings.

● In 2022, we sold three hotels, the Hyatt Centric Chicago Magnificent Mile, the Embassy Suites Chicago, and the Hilton Garden Inn Chicago Downtown/Magnificent Mile for a combined sale price of $197 million. The disposition of the three Chicago hotels further consolidated our portfolio into Long-Term Relevant Real Estate®.

● We invested approximately $129 million in capital improvements throughout the portfolio, including the completion of the renovation of all standard guestrooms and bathrooms at the Hyatt Regency San Francisco and the completion of the total redesign of the ground floor food and beverage venues at the

PROXY SUMMARY

Hilton San Diego Bayfront. Additionally, we have made significant progress on the renovation and repositioning of the Renaissance Washington DC to the Westin Washington DC Downtown, including the completion of the meeting space renovation, and considerable progress on the renovation of guestrooms, lobby and food and beverage offerings, all of which are anticipated to be completed in the second half of 2023.

● We invested nearly $15 million in a variety of back-of-house building systems, natural disaster preparations and environmental projects, including the completion of the solar conversion at the Wailea Beach Resort, installing full-backup generation at the Montage Healdsburg and the Four Seasons Resort Napa Valley, upgrading or replacing air handling units, installing water filtration stations, installing bulk amenity dispensers, upgrading fire alarm systems, upgrading building management systems, retrofitting or overhauling cooling towers, as well as several other building system upgrades intended to reduce overall energy consumption.

**Extended our debt maturities and made more prudent use of our leverage capacity while maintaining a strong and flexible balance sheet.**

● Amended our corporate credit agreement which expanded the Company's unsecured borrowing capacity and extended the maturity of the in-place loans by 4 to 5 years.

● Ended 2022 with a consolidated debt and preferred equity to consolidated total capitalization ratio of approximately 35%.

● Maintained a year-end unrestricted cash balance of $101 million and retained full availability on the Company's $500 million revolving credit facility.

**Returned approximately $129 million of capital to our common stockholders in 2022 through a combination of dividends and share repurchases.** 

● Reinstated our common dividend in the third quarter and declared $21 million of common dividends in 2022.

● Repurchased $108 million of common stock during 2022 at an average price of $10.56 per share. The average repurchase price represents a significant discount to the prevailing consensus estimates of the Company's net asset value and implied an attractive multiple on our stabilized cash flow.

#### How do I vote?
You can ensure that your shares are voted at the meeting by completing, signing, dating and returning the enclosed proxy form in the envelope provided.

If you own your shares through a bank or broker, you may be eligible to authorize a proxy to vote your shares electronically over the Internet or by telephone. A large number of banks and brokerage firms are participating in the ADP Investor Communication Services ("ADP") online program. This program provides eligible stockholders who receive a paper copy of the Annual Report and proxy statement the opportunity to authorize a proxy to vote via the Internet or by telephone. If your bank or brokerage firm is participating in ADP's online program, your voting form will provide instructions. Stockholders who authorize a proxy to vote through the Internet or telephone should be aware that they may incur costs to access the Internet, such as usage charges from telephone companies or Internet service providers, and that these costs must be borne by the stockholder.

Attention: Secretary

#### What if I return my proxy but do not mark it to show how I am voting?
If your proxy card is signed and returned without specifying your choices, your shares will be voted as recommended by the Board.

#### What are the Board's recommendations?
The Board recommends that you vote **FOR** each of the nominees for director in Proposal 1; **FOR** Proposal 2 to ratify the Audit Committee's appointment of Ernst & Young LLP to act as the independent registered public accounting firm for the fiscal year ending December 31, 2023; **FOR** Proposal 3 to approve, on a non – binding, advisory basis, the compensation of our NEOs as set forth in this proxy statement; and **EVERY ONE YEAR** in Proposal 4 as the frequency of holding future Say-on-Pay Votes.

#### What vote is required to approve each proposal?
*Election of Directors:* There is no cumulative voting in the election of directors. In an uncontested election, a director shall be elected by an affirmative vote of a majority of the votes cast at a meeting of stockholders duly called and at which a quorum is present; that is, a nominee will be elected as a director only if the number of votes cast "for" such nominee exceeds the number of votes "against" or "withheld" with respect to that nominee. Any shares not voted, whether by abstention or "broker non – vote" (i.e., shares held by a broker or nominee which are represented at the meeting, but with respect to which such broker or nominee is not instructed to vote and has not voted on a particular proposal, or otherwise), have no effect on the vote.

*Ratification of Appointment of Independent Registered Public Accounting Firm:* This proposal requires the affirmative vote of a majority of the votes cast at a meeting of stockholders duly called and at which a quorum is present. Any shares not voted (whether by abstention, "broker non – vote" or otherwise) have no effect on the vote.

*Advisory Say-on-Pay Vote:* This proposal requires the affirmative vote of a majority of the votes cast at a meeting of stockholders duly called and at which a quorum is present. Any shares not voted (whether by abstention, "broker non-vote" or otherwise) have no effect on the vote.

*Advisory Vote on the Frequency of Holding Future Say-on-Pay Votes:* The affirmative vote of a majority of the votes cast at a meeting of stockholders duly called and at which a quorum is present shall be sufficient to approve any of

the three alternative frequencies pursuant to this proposal. If none of the frequency alternatives receives a majority of the votes cast, we will consider the alternative that receives the most votes to be the alternative selected by stockholders. Any shares not voted (whether by abstention, "broker non-vote" or otherwise) have no effect on the vote.

#### What constitutes a quorum?
The presence of the owners of at least a majority (greater than 50%) of the aggregate number of shares of common stock entitled to vote at the Annual Meeting constitutes a quorum. Presence may be in person or by proxy. You will be considered part of the quorum if you return a signed and dated proxy card, if you authorize a proxy to vote by telephone or the Internet, or if you attend the Annual Meeting.

Abstentions and "broker non – votes" are counted as present and entitled to vote for purposes of determining a quorum. A "broker non – vote" occurs when the broker or other entity is unable to vote on a proposal because the proposal is non – routine and the owner does not provide instructions. Rules of the New York Stock Exchange ("NYSE") determine whether proposals presented at stockholder meetings are "routine" or "non - routine." If a proposal is routine, a broker or other entity holding shares for an owner in street or beneficial name may vote on the proposal without voting instructions from the owner. If a proposal is non -routine, the broker or other entity may vote on the proposal only if the owner has provided voting instructions. The ratification of independent public accountants is the only routine matter to be voted on at the Annual Meeting. There are no rights of appraisal or similar dissenters' rights with respect to any matter to be acted upon pursuant to this proxy statement.

#### What if other items come up at the Annual Meeting and I am not there to vote?
We are not now aware of any matters to be presented at the Annual Meeting other than those described in this proxy statement. When you return a signed and dated proxy card or provide your voting instructions by telephone or the Internet, you give the proxy holders (the names of whom are listed on your proxy card) the discretionary authority to vote on your behalf on any other matter that is properly brought before the Annual Meeting.

#### Can I change my vote?
You can change your vote by revoking your proxy at any time before it is exercised in one of four ways:

● Notify Sunstone's Secretary (David M. Klein, c/o Sunstone Hotel Investors, Inc., 15 Enterprise, Suite 200, Aliso Viejo, California 92656) in writing before the Annual Meeting that you are revoking your proxy;

● Submit another proxy with a later date;

● If you own shares through a bank or broker that provides for voting by telephone or the Internet, submit your voting instructions again by telephone or the Internet; or

● Vote in person at the Annual Meeting.

#### What does it mean if I receive more than one proxy card?
Some of your shares are likely registered differently or are in more than one account. You should vote each of your accounts by mail, or if such service is provided by a bank or broker that holds your shares, by telephone or the Internet. If you mail proxy cards, please sign, date and return each proxy card to ensure that all of your shares are voted.

If you hold your shares in registered form and wish to combine your stockholder accounts in the future, you should contact our transfer agent, American Stock Transfer and Trust Company, LLC, at 1 -800- 937- 5449. Combining accounts reduces excess printing and mailing costs, resulting in savings for Sunstone, that benefit you as a stockholder.

QUESTIONS AND ANSWERS ABOUT HOW TO VOTE YOUR SHARES

#### What if I receive only one set of proxy materials although there are multiple stockholders at my address?
If you and other residents at your mailing address own shares in "street name" (that is, through a broker or other nominee), your broker or bank may have sent you a notice that your household will receive only one Annual Report and proxy statement, or Notice Regarding the Availability of Proxy Materials, for each company in which you hold shares through that broker or bank. This practice of sending only one copy of proxy materials is known as "householding." If you did not respond that you did not want to participate in householding, you were deemed to have consented to the process. If the foregoing procedures apply to you, your broker has sent one copy of our Annual Report and proxy statement, or Notice Regarding the Availability of Proxy Materials, to your address. You may revoke your consent to householding at any time by contacting your broker or bank. The revocation of your consent to householding will be effective 30 days following its receipt. **If you did not receive an individual copy of this proxy statement or our Annual Report, we will send a copy to you without charge if you address your written request to Sunstone Hotel Investors, Inc., 15 Enterprise, Suite 200, Aliso Viejo, California 92656, Attention: Secretary.** If you currently receive multiple copies of the Annual Report and proxy statement, or Notice Regarding the Availability of Proxy Materials, at your address and you would like to request householding of your communications, you should contact your broker or bank.

#### How do I submit a stockholder proposal for inclusion in the proxy statement for next year's annual meeting?
Stockholder proposals may be submitted for inclusion in the proxy statement for our 2024 annual meeting of stockholders ("2024 Annual Meeting"), after the Annual Meeting, but must be received no later than 5:00 p.m. Pacific Time on November 23, 2023. Proposals should be sent via registered, certified, or express mail to Sunstone Hotel Investors, Inc., 15 Enterprise, Suite 200, Aliso Viejo, California 92656, Attention: Secretary. See also "Stockholder Proposals for the 2024 Annual Meeting" later in this proxy statement.

#### What do I need to do to attend the Annual Meeting?
If you are a holder of record, you should indicate on your proxy card that you plan to attend the Annual Meeting by marking the box on the proxy card provided for that purpose.

For the safety and comfort of our stockholders, admission to the Annual Meeting will be restricted to:

● Stockholders of record as of the close of business on March 6, 2023 or their authorized proxies;

● Representatives of the press or other news media with proper credentials;

● Employees and representatives of Sunstone whose job responsibilities require their presence at the meeting.

Please note that space limitations may make it necessary to limit attendance. Admission to the meeting will be on a first come, first-served basis. No more than two representatives of any corporate or institutional stockholder will be admitted to the Annual Meeting. You may obtain directions to the Annual Meeting in the Investor Relations section of our website at www.sunstonehotels.com or by calling us at 1-949-330-4000.

*Board*. The business and affairs of Sunstone are managed under the direction of our Board. Our Board has responsibility for establishing broad corporate policies and for the overall performance of Sunstone, rather than for day -to- day operating details. Our Board currently consists of seven directors.

The proxy holders named on the proxy card intend to vote for the election of the seven nominees listed below. The Nominating and Corporate Governance Committee selected these nominees, which selection was ratified by the Board. If you do not wish your shares to be voted for particular nominees, you can so indicate on the proxy card or, if your shares are held through a bank or broker and you are authorizing a proxy to vote by telephone or the Internet, by following the instructions provided when you access the telephone or Internet proxy facilities.

If at the time of the meeting one or more of the nominees have become unable to serve, shares represented by proxies will be voted for the remaining nominees and for any substitute nominee or nominees designated by the Nominating and Corporate Governance Committee. If one or more nominees have become unable to serve, the Board may, in accordance with our bylaws, reduce the size of the Board or may leave a vacancy until a nominee is identified. Each of the nominees has consented to act as a director if duly elected and qualified and the Nominating and Corporate Governance Committee knows of no reason why any of the nominees will be unable to serve.

Directors elected at the Annual Meeting will hold office until the 2024 Annual Meeting and until their successors have been elected and qualified. For each nominee, there follows a brief listing of principal occupation for at least the past five years, other major affiliations and age as of March 1, 2023. Each of the nominees is currently a director of the Company.

PROPOSALS REQUIRING YOUR VOTE

*Vote required*. Directors will be elected by a majority of the votes cast. Any shares not voted, whether by abstention, "broker non - vote" or otherwise, will have no impact on the vote.

Our Corporate Governance Guidelines and bylaws provide a majority voting standard in uncontested director elections. A director nominee will be elected to the Board only if the number of votes cast "for" such nominee's election exceeds the number of votes cast "against" or "withheld" with respect to such nominee's election (with abstentions and broker non-votes not counted as votes cast either for or withheld in such election).

If an incumbent nominee for director fails to receive the required majority vote in a director election, our Corporate Governance Guidelines require that he or she tender his or her resignation as a director for consideration by the Nominating and Corporate Governance Committee, and ultimately the Board. Our Nominating and Corporate Governance Committee will evaluate the circumstances of the failed election and will make a recommendation regarding how to act upon the tendered resignation to the full Board, taking into consideration the best interests of the Company and its stockholders. After considering the recommendation of the Nominating and Corporate Governance Committee, the full Board will then act upon the resignation, and will publicly disclose its decision regarding the tendered resignation and its rationale within 90 days of the certification of the election results. If the Board accepts the resignation, the nominee will no longer serve on the Board. If the Board rejects the resignation, the nominee will continue to serve until his or her successor has been duly elected and qualified or until his or her earlier disqualification, death, resignation, or removal. Notwithstanding the foregoing, the Board shall be required to accept any resignation tendered by a nominee who is already serving as a director if such nominee shall have received more votes "against" or "withheld" than "for" his or her election at each of two consecutive annual meetings of stockholders for the uncontested election of directors at which a quorum was present.

| &nbsp;&nbsp;**PROPOSAL**<br>**2** | &nbsp;&nbsp;![Graphic](sho-20230504xdef14a_a031.jpg) | **The Board recommends that our stockholders vote FOR the ratification of the appointment of Ernst & Young LLP as our independent registered public accounting firm for 2023.** |

---

The Audit Committee has selected and appointed the firm of Ernst & Young LLP to act as our independent registered public accounting firm for the year ending December 31, 2023. Ernst & Young LLP has audited the financial statements for us since our initial public offering on October 26, 2004.

Although stockholder ratification of the appointment of our independent auditor is not required by our bylaws or otherwise, we are submitting the selection of Ernst & Young LLP to our stockholders for ratification as a matter of good corporate governance practice. Even if the selection is ratified, the Audit Committee in its discretion may select a different independent registered public accounting firm at any time if it determines that such a change would be in the best interests of the Company. If our stockholders do not ratify the Audit Committee's selection, the Audit Committee will take that fact into consideration, together with such other factors it deems relevant, in determining its next selection of our independent registered public accounting firm.

In selecting Ernst & Young LLP as the Company's independent registered public accounting firm, the Audit Committee considered many factors, including the quality of its ongoing discussions with Ernst & Young LLP's representatives, the length of time the firm has been engaged, the appropriateness of fees, the experience and professional qualifications of Ernst & Young LLP, and Ernst & Young LLP's programs and processes for maintaining its independence. Furthermore, in accordance with SEC rules and Ernst & Young LLP's policies, lead engagement partners are subject to rotation requirements to limit the number of consecutive years the lead partner may provide services. For lead audit partners, the maximum number of consecutive years of service in that capacity is five years. We select the Company's lead audit partner pursuant to this rotation policy following meetings between the chair of the Audit Committee and candidates for that role, as well as discussions by the full Audit Committee, members of the Board and management.

The Audit Committee believes that the continued retention of Ernst & Young LLP as the Company's independent external auditor is in the best interests of the Company and its stockholders. The Board believes the Company receives significant benefits from the extensive history Ernst & Young LLP has with the Company. These benefits include:

● the high quality of their audit work and accounting advice, and their institutional knowledge of our business operations, key risks, accounting policies, financial systems and internal control framework;

● a competitive fee structure because of Ernst & Young LLP's familiarity with the Company;

● the significant time and expense that would be avoided by the Company to onboard a new auditor; and

● their commitment to maintaining their independence from the Company.

Representatives of Ernst & Young LLP are expected to be present at the Annual Meeting. These representatives will have an opportunity to make a statement if they so desire and will be available to respond to appropriate questions.

You can find more information about our relationship with Ernst & Young LLP on page 74 of this proxy statement.

*Vote required*. Ratification of the appointment of Ernst & Young LLP requires a majority of the votes cast. Any shares not voted, whether by abstention, "broker non - vote" or otherwise, have no impact on the vote.

| &nbsp;&nbsp;**PROPOSAL**<br>**3** | &nbsp;&nbsp;![Graphic](sho-20230504xdef14a_a023.jpg) | **The Board recommends that our stockholders vote FOR the approval (on a non-binding, advisory basis) of the compensation of the NEOs as disclosed in this proxy statement.** |

---

Section 14A of the Securities Exchange Act of 1934, as enacted as part of the Dodd - Frank Wall Street Reform and Consumer Protection Act in July 2010 ("Dodd Frank Act") requires us to submit to our stockholders a non - binding advisory vote to approve the compensation of the NEOs listed in the Summary Compensation Table of this proxy statement, commonly referred to as a "say - on - pay" vote.

The Board has approved the submission of the following resolution to the Company's stockholders for approval at the Annual Meeting:

"Resolved, that the stockholders hereby approve, on an advisory basis, the compensation of the Company's Named Executive Officers as disclosed in the Company's 2023 proxy statement pursuant to the disclosure rules of the Securities and Exchange Commission (which disclosure includes the Compensation Discussion and Analysis, the Summary Compensation Table and the other executive compensation tables and related discussion)."

As described more fully in the "*Compensation Discussion and Analysis*" beginning on page 40 of this proxy statement, the Company's executive compensation program is designed to attract, motivate and retain talented executives through competitive compensation arrangements that, within appropriate risk parameters, provide strong financial incentives for the NEOs to maximize stockholder value. The compensation program is designed to achieve these objectives through a combination of the following types of compensation: base salary, annual cash incentive bonus and equity incentive awards. Base salary is intended to provide a baseline level of compensation for our NEOs. The remaining types of compensation, which in the aggregate represent the majority of our NEOs' target total compensation opportunities, tie compensation directly to the achievement of corporate and individual objectives. Highlights of the Company's executive compensation program include the following:

● **We pay for performance**. Our executive compensation program is weighted towards performance-based at-risk compensation, rather than fixed compensation. Specifically, the at-risk portion of our NEO compensation program is designed to reward performance relative to financial, stockholder return and other metrics that we believe best align management with stockholder interests. Under the new NEO program, on average, approximately 62% of our Current NEO's total target compensation is considered at-risk.

● **We maintain a clawback polic** y. Each of our NEOs are subject to a compensation recovery policy that provides the Board the ability to recover an executive's incentive compensation, including bonus, incentive payment, or other cash compensation or equity-based award grants, earned and/or received by the NEO following an accounting restatement due to fraudulent, willful, or grossly negligent misconduct.

● **We require our CEO and other executives to have a meaningful ownership interest in the Compan** y. Our executive officer stock ownership policy requires that on or before January 1 of the year following the fourth anniversary of the CEO or President or other executive officers appointment to such position (i) the CEO or President will own and retain shares of the Company's common stock having a value equal to at least six times his or her annual base salary, (ii) each Executive Vice President will own and retain shares of the Company's common stock having a value equal to at least three times his or her annual base salary, and (iii) each Senior Vice President who is considered an "executive officer" will own and retain shares of the Company's common stock having a value equal to at least two times his or her annual base salary. Our Compensation Committee believes that requiring the CEO and other executive officers to maintain a meaningful ownership interest in the Company aligns the interests of the CEO and other executive officers with those of our stockholders.

● **We maintain a double trigger requirement for acceleration of equity awards in connection with a Change of Control.** To best align with our stockholders' interests, we maintain a "double trigger" (requiring

both a change in control and qualifying termination of employment) in order for an employee to receive accelerated vesting of equity awards in connection with a Change of Control.

● **We solicit independent compensation advice**. Our Compensation Committee retains Ferguson Partners Consulting ("FPC"), an independent compensation consultant, for purposes of advising and consulting with respect to the compensation of our NEOs.

The Compensation Committee and the Board believe that these policies are effective at incentivizing the achievement of the Company's strong financial performance.

At the 2023 annual meeting, stockholders are being asked to indicate how frequently they believe we should seek an advisory Say-on-Pay Vote (the "Frequency Proposal"). Our Board has recommended that our stockholders vote for a frequency of one year, and thus we currently expect our next Say-on-Pay Vote (after the vote on this Proposal 3) will be held at our annual meeting in 2024.

*Vote required*. The affirmative vote of a majority of the votes cast will be required to approve, on a non - binding, advisory basis, the Say-on-Pay Vote. Any shares not voted, whether by abstention, "broker non - vote" or otherwise, have no impact on the vote.

The stockholder vote on executive compensation is an advisory vote only, and it is not binding on the Company, the Board or the Compensation Committee. Although the vote is non - binding, the Compensation Committee and the Board value the opinions of the stockholders and will consider the outcome of the vote when making future compensation decisions.

---

The Dodd-Frank Act enables our stockholders to indicate how frequently they believe we should seek an advisory Say-on-Pay Vote. We are seeking an advisory, non-binding determination from our stockholders as to the frequency with which stockholders would like to have an opportunity to provide an advisory approval of our executive compensation program. We are providing stockholders the option of selecting a frequency of every one, two or three years, or abstaining.

*Voting recommendation.* The Board recommends that future Say-on-Pay Votes occur every one year until the next frequency vote.

*Vote required.* Stockholders are not being asked to approve or disapprove the Board's recommendation, but rather to indicate their choice among those say-on-pay frequency options. In order for any of the three alternative frequencies to be approved, it must receive a majority of the votes cast on this proposal. Because there are four choices, it is possible that none of the alternative frequencies will receive a majority of the votes cast. However, stockholders will still be able to communicate their preference with respect to the frequency of holding future Say-on-Pay Votes by choosing from these alternatives. In the event that none of the frequency alternatives receives a majority of the votes cast, we will consider the alternative that receives the most votes to be the alternative selected by stockholders. Abstentions and broker non-votes will not be treated as votes cast and, accordingly, will have no effect on the outcome of the vote on this proposal.

This stockholder vote is an advisory vote only, and therefore will not have any binding legal effect on the Company or our Board. However, our Board will consider the results of the vote on this proposal in its decision regarding the frequency of holding future Say-on-Pay Votes.

### COMPANY INFORMATION

### CORPORATE GOVERNANCE
In light of applicable legal requirements, such as the Sarbanes – Oxley Act of 2002 and related rules promulgated by both the NYSE and the SEC, we provide the following discussion to inform you of our efforts to assure that we employ best practices in our corporate governance. We have also established conflict of interest and other policies to serve the long – term interests of our stockholders and further align the interests of our directors and management with our stockholders.

### CONFLICT OF INTEREST POLICY
We have adopted a policy which provides that the approval of our Nominating and Corporate Governance Committee is required for any transaction involving the Company and any of our directors, officers or employees, or any entity in which any of our directors, officers or employees is employed or has an interest of more than 5%.

### CODE OF BUSINESS CONDUCT AND ETHICS
We have adopted a Code of Business Conduct and Ethics, which requires, among other things, that directors, officers and employees act with integrity. The Code of Business Conduct and Ethics also prohibits our directors, officers and employees from taking (or directing to a third party) a business opportunity that is originated through the use of corporate property, information or position, unless we have already been offered the opportunity and turned it down, in which case our Nominating and Corporate Governance Committee must in any event approve the director, officer or employee interest therein. More generally, our directors, officers and employees are prohibited from using corporate property, information, or position for personal gain.

### POLITICAL CONTRIBUTIONS POLICY AND TRADE ASSOCIATION MEMBERSHIPS
It is the Company's policy that funds are not used directly to contribute to candidates, campaigns, and political party committees. The Legal Department oversees compliance with our Company policy and may make exceptions where permissible under law and regulations. However, we are a member of certain industry associations which have a fee for membership or contribution for specific activities. The Company believes participation in these industry associations provides the opportunity to enhance stockholder value through involvement in public policy processes, networking, building of business skills, sharing collective best practices, and monitoring industry policies and market trends. Pursuant to the Company's Code of Business Conduct and Ethics, total Company contributions for political advocacy purposes are reported as less than $20,000 in 2022.

### PLEDGING AND HEDGING POLICIES
We maintain pledging and hedging policies applicable to our directors, officers, and other employees (collectively referred to in this section only as "insiders" and individually as an "insider").

*Margin Accounts and Pledges.* Securities held in a margin account or pledged as collateral for a loan may be sold without the insider's consent by the broker if the insider fails to meet a margin call or by the lender in foreclosure if the insider defaults on the loan. Because a margin or foreclosure sale may occur at a time when the insider is aware of material nonpublic information or otherwise is not permitted to trade in Company securities, insiders are **prohibited** from holding Company securities in a margin account or pledging Company securities as collateral for a loan.

*Hedging Transactions.* Certain forms of hedging or monetization transactions, such as zero – cost collars and forward sale contracts, involve the establishment of a short position in the Company's securities and limit or

[**Table of Contents**](#TOC)

COMPANY INFORMATION

eliminate an insider's ability to profit from an increase in the value of the Company's securities. Such transactions are complex and involve many aspects of the federal securities laws, including filing and disclosure requirements. Therefore, the Company **prohibits** insiders from any hedging transactions.

Our Environmental Policy is designed to identify our environmental impact, drive sustainability within our portfolio and raise environmental awareness among our stakeholders. Key elements of our Environmental Sustainability program include:

Sunstone is committed to seeking and investing in new ESG innovations and practices to implement across our portfolio, including low-carbon solutions, initiatives to reduce the environmental footprint of our hotels and programs that result in positive community impact.

#### Social Responsibility
We strive to create a healthy and supportive workplace for Sunstone employees, including the establishment of a safe, inclusive, and accommodating work environment, together with competitive wages and benefits, and career development opportunities. We also work with our hotel brands and operators to offer the financial resources that enable them to provide the same support for hotel associates. Furthermore, we seek to support the communities where we work and own hotels through community outreach programs and fundraising efforts.

***Social Responsibility Governance.*** We maintain a Human Rights & Labor Rights Policy, Code of Business Conduct and Ethics and a Vendor and Business Partner Code of Conduct. All three policies are designed to drive social impact including DEI&B and to raise social responsibility and awareness among our stakeholders. Our program and initiatives include addressing social responsibility at our corporate office, our hotels, and the

COMPANY INFORMATION

communities in which we work and own hotels. Likewise, our Vendor and Business Partner Code of Conduct encourages our suppliers, vendors, tenants, and all other business partners to operate in a manner that seeks to minimize environmental and social risks and the impacts of their products and services.

***Community Engagement.*** Sunstone's Community Involvement Program aims to improve community health and well-being, provide assistance or support in case of disaster, and support charities and community groups. Our employees and Board directors have the opportunity to donate to qualifying organizations through our Matching Charitable Gifts Program where the Company will match dollar for dollar all donations made up to $5,000 per individual. Additionally, in 2022, we adopted a Volunteer Time-Off policy that provides full-time corporate employees an opportunity to use up to eight hours of paid work time per year towards volunteerism at qualifying charitable organizations.

***DEI&B.*** Sunstone recognizes the value of different perspectives, backgrounds and experiences in our workplace, and seeks to foster a Company culture of belonging, where all employees are encouraged to be their authentic selves. In 2022, we updated the name of our internal committee to Diversity, Equity, Inclusion and Belonging to better emphasize inclusion and belonging while advancing our DEI&B commitment. In 2022, 100% of Sunstone employees participated in DEI&B training through interactive workshops. As of December 31, 2022, we had 40 employees, of which 38% identified as female and 62% identified as male. Additionally, 30% of our workforce identified as being from an underrepresented community.

### INDEPENDENCE OF DIRECTORS AND COMMITTEES
The Board has determined that all directors of the current Board are independent as defined under the NYSE's rules and will continue to be independent if the slate of directors up for election in Proposal 1 of this proxy statement are elected. Directors who serve on the Compensation Committee and the Nominating and Corporate Governance Committee are also subject to these independence requirements. Directors who serve on the Audit Committee are subject to these and additional independence requirements.

To be considered independent under the NYSE's rules, the Board must determine that a director does not have a material relationship with Sunstone and/or its consolidated subsidiaries (either directly or as a partner, stockholder, or officer of an organization that has a relationship with any of those entities).

The Board undertakes on an annual basis a review of the independence of the directors nominated for election at the upcoming annual meeting. During this review, the Board considers the transactions and relationships between each director or any member of his or her immediate family and Sunstone and its subsidiaries and affiliates as reported under "Certain Relationships and Related Party Transactions" below. The Board also examines transactions and relationships between directors or their affiliates and members of senior management or their affiliates. The purpose of this review is to determine whether any such relationships or transactions are inconsistent with a determination that such director is independent.

As a result of this review, the Board affirmatively determined that each member of the Board is independent of Sunstone and its management under the independence standards of the NYSE.

### THE BOARD LEADERSHIP STRUCTURE
Mr. Pasquale, who serves as our Chairman of the Board, is independent of the CEO. Assuming that the nominees listed in Proposal 1 are elected as directors at the Annual Meeting, we expect Mr. Pasquale will continue to serve as our Chairman of the Board.

The role of the Chair of the Board or lead independent director is to coordinate the activities of the independent directors, coordinate with the CEO, or management, and the corporate secretary to set the agenda for Board meetings and chair executive sessions of the independent directors. The Chair of the Board also provides leadership to the Board and upholds high corporate governance and ethical standards, communicates effectively with management on a regular basis, provides support and advice to the CEO and management, facilitates communication between and among the independent directors and management, takes a lead role in the Board's

2023 Proxy Statement&nbsp;&nbsp;&nbsp;&nbsp; 29

[**Table of Contents**](#TOC)

COMPANY INFORMATION

self – assessment and evaluation processes, and performs the other duties either specified in the Corporate Governance Guidelines or assigned from time to time by the Board.

Our Board believes its leadership structure is appropriate as it effectively allocates authority, responsibility and oversight between management and the independent members of our Board. It accomplishes this by giving management primary responsibility for the operational leadership and strategic direction of the Company, while facilitating our Boards' independent oversight of management, promoting communication between management and our Board, and supporting our Boards' consideration of key governance matters.

### DIRECTOR ATTENDANCE AT MEETINGS
Each of our directors is encouraged to attend each annual meeting of stockholders and all meetings of the Board. The Board held ten Board meetings and acted by written consent five times in 2022. The Compensation Committee acted by written consent once in 2022. During 2022, all directors attended 100% of the Committee meetings on which they served during the periods in which they served on such Committees. All directors attended each Board meeting, except one director who missed one meeting due to an excused family matter. Director attendance was greater than 75% at all Board meetings. Although we do not have a policy requiring directors to attend our annual meetings of stockholders, all our directors attended our annual meeting of stockholders in 2022.

### STOCKHOLDER ENGAGEMENT
We firmly believe that developing and maintaining long-term transparent relationships with our stockholders is critical to our Company's ability to create long-term value. We are committed to on-going stockholder engagement activities which allows our Board to remain informed of our stockholders' perspectives and priorities and can incorporate these perspectives into the Board discussions and decisions.

***Engagement Topics.*** We strive to maintain an active dialogue with stockholders to ensure a diversity of perspectives is thoughtfully considered on issues including strategy, business performance, risk, culture and workplace topics, compensation practices, and ESG issues. Over the course of the year, we actively engaged with stockholders holding a majority of our outstanding shares of common stock. Among the topics we discussed were:

✓ Executive management transition and the impact on our long-term strategy;

✓ Company's long-term strategy including opportunities for growth;

✓ Board governance including diversity commitment and initiatives;

---

| | |
|:---|:---|
| ✓ | NEO compensation program and response to our 2022 Say-On-Pay Vote; |

---

✓ Renovation and capital investment strategy;

✓ Financial performance and market positioning; and

✓ Corporate Responsibility / ESG program and initiatives including climate-related risks and opportunities.

***Engagement Activities***. Our stockholder and investor outreach activities include investor road shows, analyst and investor meetings, property tours, and industry conferences. We also communicate with stockholders and other key stakeholders through various channels, including our annual report and SEC filings, proxy statement, news releases, Corporate Responsibility Report, investor presentations, correspondence, our website and on-going open dialogue. Our quarterly earnings conference calls are open to the public. These calls are available in real time with archived webcasts and transcripts available on our website for a period of time.

### RISK OVERSIGHT
The Board is responsible for the Company's overall risk management strategy. The Board has delegated the oversight of certain risk areas to the various Committees. Each Committee provides periodic reports to the Board on their primary areas of risk. Company management is responsible for the day – to – day risk management processes and for providing quarterly (at a minimum) updates to the Committees and the Board. We, together with the Board, believe this division of responsibilities is the most effective approach for addressing the risks facing the Company. The chart below summarizes the primary areas of risk oversight for the Board and its Committees.

---

| | |
|:---|:---|
| **Board / Committee** | **Primary Areas of Risk Oversight Responsibilities** |
| **Board** | <br>✔ Strategic, financial and execution risks and exposures associated with the annual operating plan and the Company's long-term strategic plan; <br>✔ Acquisitions and divestitures, capital investments, capital markets, and other investment opportunities;<br>✔ Major litigation and regulatory exposures; and<br>✔ Corporate culture and its effectiveness on advancing the Company's strategy.<br>|

| **Nominating and Corporate Governance Committee** | <br>✔ Board refreshment including the identification of qualified candidates to become Board members;<br>✔ Corporate governance programs, policies and procedures including Board structure and Board Committee composition; and<br>✔ ESG policies, programs and practices, including climate change, social responsibility, resource scarcity, DEI&B, and human rights.<br>|
| **Compensation Committee** | <br>✔ Compensation plans, policies and procedures including NEO compensation, stock ownership and incentive-compensation plans, Director compensation, executive retention and succession planning;<br>✔ Compensation practices in order to ensure (i) an appropriate balance of risk and reward compared to our overall business strategy; and (ii) incentives to our employees do not lead to excessive or inappropriate risks that could have a material adverse effect on the Company; and<br>✔ Human capital related programs, including our employee engagement initiatives and talent management practices.<br>|

COMPANY INFORMATION

*Board Refreshment*. Our Board remains committed to active board refreshment to ensure optimal board structure and composition. The Nominating and Corporate Governance Committee focuses on obtaining a desired mix of knowledge, skills, experience, perspective, and diversity relevant to the Company's strategic direction. The Nominating and Corporate Governance Committee recommends, among other things, whether the existing Board contains the appropriate size, structure and composition, whether some or all of the incumbent directors should be recommended to the Board for re - nomination and whether the Board should be enlarged to include additional directors.

The Nominating and Corporate Governance Committee will consider potential director nominee candidate recommendations from various sources, including any member of the Board or senior management. The Nominating and Corporate Governance Committee may also retain a third - party search firm to identify candidates. The Nominating and Corporate Governance Committee also considers recommendations for nominees that are timely submitted by stockholders and only if such recommendations are delivered in the same manner prescribed by the advance notice provisions contained in Article II, Section 2.11 of our bylaws for stockholder proposals. In addition to satisfying the timing, ownership and other requirements specified in Article II, Section 2.11 of our bylaws, a stockholder's notice must set forth as to each person whom the stockholder proposes to recommend that the Committee nominate for election to the Board all information relating to such person that is required to be disclosed in solicitations of proxies for election of directors in an election contest, or is otherwise required, in each case pursuant to Regulation 14A under the Exchange Act and our bylaws (including such person's written consent to being named in the proxy statement as a nominee and to serve as a director if elected). Properly communicated stockholder recommendations will be considered in the same manner as recommendations received from other sources.

*Commitment to Diversity at the Company and on the Board*. The Company is committed to diversity at the Board level. Our Board considers diversity, including gender, ethnicity and other underrepresented communities when considering nominations to the Board and will continue to endeavor to include women and individuals from underrepresented communities in the qualified pool from which new director candidates are selected. The Board's objective is to have a Board comprised of individuals who by occupation, background and experience are in a position to make a strong, positive contribution to the Company and its stockholders.

*Current Committee Membership*. The table below summarizes the membership information for the committees of the Board as of March 22, 2023:

The Board, at the recommendation of the Nominating and Corporate Governance Committee, periodically reviews and modifies committee appointments.

*Executive Sessions of Independent Directors*. Each member of the Board is currently an independent, non-employee director. The independent, non-employee directors held executive sessions at least once each quarter in 2022 and held other meetings relating to corporate governance during the year. While Mr. Pasquale served as Interim CEO and Executive Chairman, executive sessions were held both with and without Mr. Pasquale. Following the Annual Meeting, we expect that all of our directors will continue to be members of the Board, and that Mr. Pasquale will continue to preside over executive sessions of the independent directors.

### STOCK OWNERSHIP

### STOCK OWNERSHIP REQUIREMENTS
We maintain a stock ownership policy for our executive officers because we believe that requiring our executive officers to maintain a meaningful ownership interest in the Company aligns the interests of the executive officers with those of our stockholders (i.e., the executive officer will experience the same downside risk and upside potential as our stockholders).

---

| | |
|:---|:---|
| **Stock Ownership Requirements** | **Stock Ownership Requirements** |
| &nbsp;&nbsp;CEO and/or President | 6x base salary |
| &nbsp;&nbsp;Executive Vice President | 3x base salary |
| &nbsp;&nbsp;Senior Vice President | 2x base salary |
| &nbsp;&nbsp;Independent Director | 5x annual cash retainer |

---

The policy provides that, on or before January 1 of the year following the fourth anniversary of the CEO or President's appointment to such position, the CEO or President will own and retain shares of the Company's common stock having a value equal to at least six times his or her annual base salary rate in effect on the December 31 immediately preceding the applicable January 1 determination date (described below). The policy further provides that, on or before January 1 of the year following the fourth anniversary of the other executive officer's appointment to such position, each executive officer will own and retain shares of the Company's common stock having a value equal to at least: (i) three times for Executive Vice Presidents, and (ii) two times for Senior Vice Presidents, his or her annual base salary rate in effect on the December 31 immediately preceding the applicable January 1 determination date (described below).

We also maintain a stock ownership policy for our independent directors, under which each existing independent director, on or before January 1 of the year following the fifth anniversary of such director's election to the Board, is required to hold stock valued at no less than five times the amount of the annual cash retainer paid to such director.

To determine compliance with the stock ownership guidelines, we (a) include shares the individual director or executive officer owns outright, as well as, awarded but unvested time-based restricted shares of Company stock and (b) calculate the value of each individual's stock holdings based on the average closing price on the NYSE of the Company's common stock for the year ended immediately prior to the applicable January 1 determination date.

As of January 1, 2023, each of our executive officers and each applicable independent director (other than Mses. Leslie and Mims) met or exceeded the stock ownership requirements. Based on the policy in place as of January 1, 2023, Mses. Leslie and Mims, both of whom joined the Board in 2021, must achieve compliance by January 1, 2027 in accordance with our updated stock ownership policy.

For additional information on our "*2022 Company Highlights*" refer to pages 7 and 8 of this proxy statement.

Our Current NEOs for 2022 included Messrs. Giglia, Reyes, Springer, Klein and Ostapovicz. In addition, per SEC Rules, our former Interim CEO and former Executive Chairman, Douglas M. Pasquale, was also an NEO for 2022.

The Board and our Compensation Committee consider it our responsibility to structure our compensation program in a way that is highly aligned with the interests of our stockholders. Although the advisory stockholder vote on executive compensation is non - binding, the Compensation Committee has considered and will continue to consider the outcome of the vote when making future compensation decisions for NEOs. At our 2022 annual meeting of stockholders, 71.8% of votes cast were in favor of our Say-on-Pay proposal. As described below, our Compensation Committee adopted a new NEO compensation program in 2022 that further aligns NEO compensation with the interests and priorities of our stockholders. During 2022, management and members of our Board engaged with stockholders holding a majority of our outstanding shares of common stock regarding NEO compensation and received strong support for the new program's enhanced alignment with our stockholders' interests. At the 2023 Annual Meeting, stockholders are being asked to vote on the Frequency Proposal. Our Board has recommended that our stockholders vote for a frequency of one year, and thus we currently expect our next Say-on-Pay Vote (after the vote on Proposal 3 at our 2023 Annual Meeting) will be held at our annual meeting in 2024. The next advisory vote on the frequency of holding future Say-on-Pay Votes will be held in 2029.

In addition, the Compensation Committee seeks to attract, motivate and retain Sunstone's NEOs through competitive compensation arrangements that the Compensation Committee believes provide strong financial incentives for the NEOs to maximize stockholder value, while maintaining appropriate risk parameters.

With respect to our NEOs, our executive compensation program is weighted towards variable, rather than fixed, compensation. Specifically, all at-risk compensation, including annual cash bonuses, are designed to reward performance relative to financial and other metrics that we believe will result in favorable total stockholder returns, both in terms of absolute appreciation in the value of our shares, and relative performance as compared to our peers, taking into consideration our competitive position within the real estate industry and each executive's contributions to the Company. The Compensation Committee has also designed our NEO compensation program to reward our NEOs at levels that the Compensation Committee believes to be competitive for companies in its industry, including in part, a review of NEOs compensation levels at certain companies in a peer group, as identified below.

In 2022, our Compensation Committee made significant changes to the Company's long-term incentive compensation program in order to better align with our peers, market practices, and our stockholders' interests. Commencing with awards granted in 2022, the Compensation Committee transitioned the Company's annual grant practices for performance-based equity awards from a program granting time-based awards based on prior performance to a program granting performance-based awards tied to future performance. As a result of this change, in order to bridge the transition period between the old and new programs and maintain the same level of target stock compensation throughout the transition period, in addition to the Annual Time-Based RSAs (defined below) and Annual Performance RSUs (defined below) tied to future performance, the awards granted by the Compensation Committee in 2022 also included one-time transition awards for each NEO (other than Mr. Reyes) in the form of an award of time-based restricted stock awards, or RSAs, (the "Transition Time-Based RSAs") that vest over a two-year period and an award of performance-based restricted stock units, or RSUs, (the "Transition Performance RSUs", and together with Transition Time-Based RSAs, the "Transition Equity Awards") eligible to vest after a two-year performance period. The one-time transition awards were designed to only compensate NEOs at their existing target level of equity compensation. A summary of the key plan features is provided in the table below. No additional transition grants or promotion grants were made in 2023. Mr. Reyes was not an NEO when his annual equity award was granted in 2022, and thus his annual equity award in 2022 was in the form of time-

based RSAs which vest over a three-year period following the date of grant and was based on his past performance, as determined on the recommendation of the CEO and approved by the Compensation Committee.

### COMPENSATION COMPOSITION
The table below illustrates the 2022 target composition of cash compensation and annual equity-based award program for our Current NEOs, other than Mr. Reyes. Mr. Reyes was not an NEO when his annual equity award was granted in 2022, and thus his equity compensation, which is discussed below under "2022 Compensation Decisions – Annual Equity Awards", was not based on the 2022 NEO equity incentive program. The target compensation table excludes the Transition Equity Awards granted to our Current NEOs in February 2022 and excludes equity awards granted to Messrs. Giglia and Springer in March 2022 in connection with their promotions to CEO and President, respectively, each of which were nonrecurring awards and are not part of the annual target compensation on a go-forward basis.

COMPENSATION DISCUSSION AND ANALYSIS

### 2022 COMPENSATION DECISIONS
The Compensation Committee determines the compensation of our NEOs. It evaluates and implements appropriate policies and decisions relative to NEO salary, benefits, bonus, incentive compensation, severance, equity-based and other compensation plans.

As described in more detail below, the Compensation Committee determined fiscal year 2022 compensation for each of our NEOs based upon a review of the Company's performance (including the Company's stockholder returns), the individual performance of each NEO, total compensation paid by the Company to each NEO in prior years, and, in certain instances, taking into account certain peer group information.

Commencing with awards granted in 2022, the Compensation Committee transitioned the Company's annual grant practices with respect to performance-based equity awards to a program granting performance-based awards tied to future performance, rather than the historical practice of granting time-based awards in amounts based on the historical achievement of trailing three- and five- year RSR performance metrics. We believe that tying a majority of the NEOs' compensation to future performance aligns more closely with our stockholders' interests and priorities and provides a strong financial incentive for our NEOs to continue to maximize stockholder value. Under the modified program, annual equity awards granted in 2022 consist of performance-based RSUs (75% of award) (the "Annual Performance RSUs") and time-based RSAs (25% of award) (the "Annual Time-Based RSAs" and, together with the Annual Performance RSUs, the "Annual Equity Awards"). Annual Performance RSUs are subject to vesting based on achievement of RSR metrics over the applicable three-year performance period. Under the 2022 modified compensation program, the Current NEOs, other than Mr. Reyes, did not receive annual equity awards in 2022 based on past stockholder performance. As a result of the transition, awards granted by the Compensation Committee in 2022 included one-time Transition Equity Awards for each NEO, other than Mr. Reyes. Mr. Reyes was not an NEO when his annual equity award was granted in 2022, and thus his annual equity award in 2022 was in the form of time-based RSAs which vest over a three-year period following the date of grant and was based on his past performance, as determined on the recommendation of the CEO and approved by the Compensation Committee.

*Management's Involvement in Compensation Decisions*. The Compensation Committee exercises independent discretion and judgment in making compensation decisions after evaluating the Company's performance, the NEO's past performance (including the extent to which the NEO has met or exceeded specified targets or affected the Company's performance), and the NEO's long - term potential to enhance stockholder value. From time to time, the Compensation Committee will direct management to work with its consultant(s) in providing proposals, program design and compensation recommendations. The CEO does not provide recommendations for changes in his own compensation. Any proposed changes to CEO compensation, as well as final determinations regarding CEO compensation, are made in executive session of the Compensation Committee, without the CEO present.

*Independent Consultant*. FPC advises our Compensation Committee on compensation program design and the amounts payable to our NEOs. FPC provides our Compensation Committee with information on executive compensation trends, best practices and advice for potential improvements to the executive compensation program. FPC does not work for management, receives no compensation from the Company other than fees for its work in advising our Compensation Committee, and maintains no other economic relationships with the Company.

***Annual Base Salary*.** The Compensation Committee reviews base salaries annually, but base salaries are not automatically increased pursuant to pre - determined formulas (or otherwise) and may not be increased if, among other things, the Compensation Committee believes that other elements of compensation are more appropriate in light of the Company's stated objectives or that increases are not appropriate for other reasons. Each NEO's base salary serves as the base amount for determining annual cash bonuses and equity incentive award opportunities, which are calculated as percentages of such NEO's base salary.

The base salary payable to each of our NEOs is based on the review of the Compensation Committee described above and the following:

● an assessment of the scope of the NEO's responsibilities and leadership;

● the NEO's expertise and experience within the industry;

42 &nbsp;&nbsp;&nbsp;&nbsp;Sunstone Hotel Investors

[**Table of Contents**](#TOC)

COMPENSATION DISCUSSION AND ANALYSIS

● the Company's overall financial and business performance; and

● the NEO's contributions to the Company.

The foregoing determination is not formulaic and is not based on specific Company or individual performance objectives, but rather, is subjective and made in light of our compensation philosophy and objectives described above. The following table includes the 2022 base salary determinations for each of our NEOs.

&nbsp;&nbsp;&nbsp;&nbsp;(1) Messrs. Giglia's, Reyes's and Springer's base salaries were increased in connection with their appointments to CEO, Chief Financial Officer ("CFO") and President, respectively, on March 7, 2022. The amounts presented are on an annualized basis.

&nbsp;&nbsp;&nbsp;&nbsp;(2) Reflects Mr. Pasquale's annualized base salary as Interim CEO and Executive Chairman.

***Annual Cash Incentive Bonuses and Annual Equity Incentive Awards*.** We use annual cash incentive bonuses, granted under our Incentive Bonus Plan, and annual equity incentive awards to further motivate our NEOs by establishing relationships between the bonuses and awards, on the one hand, and the performance of the NEO and/or the Company, including RSR (discussed below) on the other. We believe that tying our NEOs' cash bonus and long-term equity compensation to quantitative metrics, aligns the interests of our NEOs with those of our stockholders and provides a strong financial incentive to maximize stockholder value.

The annual cash incentive bonus and equity incentive awards are intended to compensate our NEOs for achieving our annual financial objectives at both the corporate and hotel levels, for achieving TSR and RSR, for implementing long-term plans and strategies, and for achieving individual objectives. The annual cash incentive bonus and annual equity incentive award programs are based on performance and responsibility level rather than seniority, tenure, or other entitlement. The target annual incentive cash bonus and annual equity incentive award for each of our NEOs represent a significant percentage of such NEOs overall compensation. Performance thresholds applicable to these awards are set at levels intended to provide the NEOs with a significant incentive to enhance stockholder value.

Each year, the Compensation Committee establishes performance-based criteria, both corporate and individual, for each NEO, and the level of achievement of those criteria determines the size of the annual bonuses made to the NEO in the next calendar year. As discussed above, commencing with awards granted in 2022, the Compensation Committee transitioned the Company's annual grant practices from a program granting time-based RSA awards based on prior performance to a program granting performance-based awards tied to future performance for our NEOs. Performance-based compensation is intended to encourage our NEOs to continually improve their capabilities to enhance performance and deliver positive business results. Annual equity incentive awards are also intended to encourage ownership, foster retention through post - grant vesting schedules and align the NEOs' interests with the long - term interests and priorities of our stockholders.

***Annual Cash Incentive Bonus.*** In the first quarter of 2022, the Compensation Committee established quantitative and qualitative performance measures for the annual cash incentive bonuses for the Current NEOs. Each Current NEO's annual cash incentive bonus was based on the achievement of the corporate objectives (discussed below) and the achievement of each Current NEO's individual objectives (discussed below) weighted as set forth in the table below. Pursuant to his employment agreement, Mr. Pasquale's cash incentive bonus with respect to his service as Interim CEO and as Executive Chairman was determined by the Compensation Committee based on its evaluation of his performance in those roles.

The relative weighting of the annual cash incentive bonus objectives and each Current NEO's individual objectives are established by the Compensation Committee and reflect its analysis of the appropriate amount of emphasis to place on both corporate and individual objectives, and not any pre - determined formula or methodology. The Compensation Committee may, at its discretion, adjust criteria to account for significant intra - year transactions and circumstances.

The Committee selected four portfolio and operational metrics for the 2022 Annual Cash Incentive Bonus which is discussed in detail below.

*Annual Cash Incentive Bonus Objectives*.*** The Compensation Committee determined that the amount of the cash bonus paid to each Current NEO would be based on the achievement of both: (i) the following four Company objectives (the "Cash Incentive Bonus Objectives"), weighted as described below at Threshold, Target and Maximum, and (ii) individual objectives:

---

| | | | | | |

---

&nbsp;&nbsp;&nbsp;&nbsp;(1) Performance for these objectives is determined based on a five-point scale with an achievement of one at threshold, three at target and five at maximum, as determined by our Compensation Committee.

For the Company's Cash Incentive Bonus Objectives, the Compensation Committee established three achievement levels—"Threshold," "Target" and "Maximum," and for each achievement level, a corresponding multiple of base

COMPENSATION DISCUSSION AND ANALYSIS

salary for each Current NEO. For each of the components, the amount paid to the applicable Current NEO was the product of (a) his base salary, (b) the weighting for that component, (c) the multiple corresponding to the level of achievement and (d) the Compensation Committee's subjective assessment as to whether the Current NEO's performance warranted an increase or decrease.

Each of the Cash Incentive Bonus Objectives is further discussed below. The Cash Incentive Bonus Objectives consist of both quantitative and qualitative measures designed to advance the Company's strategic objectives. The Compensation Committee has set Target performance requirements for these objectives at a challenging level with achievement above Target requiring exceptional performance.

*Objective Number 1 – Adjusted Funds From Operations Attributable to Common Stockholder Per Share ("AFFO").* The primary objective of the AFFO per share component was to measure management's ability to oversee the financial performance of the Company. We compute the AFFO per share component by adjusting Funds From Operations ("FFO"), which we calculate in accordance with standards established by the National Association of Real Estate Investment Trusts ("Nareit"), for certain noncash or nonrecurring items. AFFO is then divided by our weighted average share count, including those shares associated with unvested time-based RSA awards, for the year ended December 31, 2022. Refer to "Non-GAAP Financial Measures" in Item 7. Management's Discussion and Analysis of Financial Condition and Results of Operations of our Annual Report on Form 10-K for the year ended December 31, 2022. This component comprises 15% of the total Cash Incentive Bonus, and 20% of the total Company Incentive Bonus.

*Objective Number 2 – Capital Recycling*. The primary objective of the Capital Recycling component was to measure management's ability to meet its business objectives through the sale of certain hotels based on future growth expectations and the redeployment of those proceeds in hotels that meet the Company's portfolio and return requirements, the strategic and opportunistic disposition of hotels, the identification of potential value creation and monetization of value within the portfolio. Capital recycling is also compared to the capital recycling activity of the Hotel REIT Peer Group (as described below). This component comprises 30% of the total Cash Incentive Bonus, and 40% of the total Company Incentive Bonus.

*Objective Number 3 – Capital Markets*. The primary objective of the Capital Markets component was to measure management's ability to meet its business objectives through recasting/extending the corporate credit facilities, extending term loans, accessing the debt and equity markets to facilitate the growth of the Company. Capital markets execution is also evaluated compared to the capital markets activity of the Hotel REIT Peer Group (as described below). This component comprises 15% of the total Cash Incentive Bonus, and 20% of the total Company Incentive Bonus.

*Objective Number 4 – Capital Investment / Rebranding*. The primary objective of the Capital Investment/Rebranding component was to measure management's ability to meet its business objective of completing the 2022 capital plan, including restoration work at the Hilton New Orleans St. Charles, guestroom renovation at the Hyatt Regency San Francisco and achieving all 2022 milestones for the Westin Washington DC Downtown conversion. An additional element was to identify future value creation opportunities throughout the portfolio. This component comprises 15% of the total Cash Incentive Bonus, and 20% of the Company Incentive Bonus Objectives.

*Individual Objectives.* The primary objective of this component was to drive individual performance and to ensure accountability with respect to individual performance throughout the calendar year. Each of the Current NEOs had individualized objectives for 2022 as follows:

● Mr. Giglia's objectives included achievement of certain corporate, ESG initiatives, financial, strategic and operational objectives, including the overall execution of the Company's business plan, transitioning CFO responsibilities to our new CFO and effectively recycling capital into future growth opportunities.

● Mr. Reyes's objectives included managing the Company's leverage levels, preparing for upcoming debt maturities, addressing covenant waivers as needed, directing the accounting and tax functions, and overseeing the Company's ESG initiatives.

● Mr. Springer's objectives included implementing the Company's portfolio management objectives, including enhancing the Company's portfolio quality through acquisitions and dispositions, evaluating third-party

[**Table of Contents**](#TOC)

COMPENSATION DISCUSSION AND ANALYSIS

manager changes, assessing ESG initiative opportunities for acquisition targets, and evaluating alternative uses of owned real estate.

● Mr. Klein's objectives included managing the legal process for all transactions, overseeing legal proceedings and regulatory filings, advising on labor matters, assessing and advising on the Company's corporate governance and risk management policies, and overseeing the Company's ESG initiatives.

● Mr. Ostapovicz's objectives included updating and executing the plans to maximize the long-term value of each Company hotel property through oversight of hotel operations, facilitating the execution of value-enhancing renovations, and implementing ESG initiatives at the hotel properties.

To determine the cash incentive bonus payable to each Current NEO, in February 2023, the Compensation Committee reviewed and assessed the performance of the Company and each Current NEO and compared such performance to the Company and individual objectives established in 2022, subject to the Compensation Committee's subjective assessment as to whether the Current NEO's performance warranted an increase or decrease. The CEO provided recommendations to the Compensation Committee for each NEO's individual performance. The Compensation Committee did not adjust the performance measures established for fiscal year 2022.

The following table summarizes all of the components of the Cash Incentive Bonus Objectives with respect to fiscal year 2022, paid in February 2023 for Messrs. Giglia, Reyes, Springer, Klein and Ostapovicz (dollar values rounded to the nearest whole dollar). Mr. Pasquale's cash bonus was paid upon completion of his service as Interim CEO and as Executive Chairman. For Messrs. Giglia and Springer, the cash bonus reflects the product of base salary multiplied by the weighting of each objective and the interpolated achieved objective multiplier (Threshold – 67.5%; Target – 135.0%; Maximum – 202.5%). For Messrs. Reyes, Klein, and Ostapovicz, the cash bonus reflects the product of base salary multiplied by the weighting of each objective and the interpolated achieved objective multiplier (Threshold – 50.0%; Target – 100.0%; Maximum – 150.0%). For Mr. Pasquale, the cash bonus with respect to his service as Interim CEO reflects the terms of his employment agreement: (Threshold – $750,000; Target – $1,850,000; Maximum – $3,000,000), and the cash bonus with respect to his service as Executive Chairman reflects the terms established by the Compensation Committee: (minimum - $600,000; maximum - $900,000). The actual amount of the cash bonus paid to Mr. Pasquale in 2022 (i) with respect to his service as Interim CEO was $1,800,000 and (ii) with respect to his service as Executive Chairman was $600,000.

***Annual Equity Incentive Awards.*** Commencing with awards granted in 2022, the Compensation Committee transitioned the Company's annual performance-based equity award practices for the NEOs to a program granting performance-based awards tied to future performance, rather than past performance. Under the modified program, in February 2022, Messrs. Giglia, Springer, Klein and Ostapovicz were each granted Annual Performance RSUs and Annual Time-Based RSAs. Seventy-five percent of each NEO's annual award was in the form of Annual Performance RSUs and 25% was in the form of Annual Time-Based RSAs. As a result of this change, in order to bridge the transition period between the old and new programs, in addition to the 2022 Annual Equity Awards, the Compensation Committee granted to each of Messrs. Giglia, Springer, Klein and Ostapovicz one-time Transition Equity Awards in the form of Transition Performance RSUs (together with the Annual Performance RSUs, the "Performance RSU Awards") and Transition Time-Based RSAs (together with the Annual Time-Based RSAs, the

"Time-Based RSA Awards"). Mr. Reyes was not an NEO when his annual equity award was granted in 2022, and thus his annual equity award in 2022 was in the form of time-based RSAs which vest over a three-year period following the date of grant and was based on his past performance, as determined on the recommendation of the CEO and approved by the Compensation Committee.

*Performance RSUs Awards*

General. Pursuant to the Performance RSU Awards, the NEOs are eligible to vest in a number of RSUs ranging from 0% to 200% of the Target number of RSUs granted, based on the Company's RSR during the applicable performance period, subject to the applicable NEO's continued service with the Company.

Performance Vesting. The Performance RSU Awards vest based on the Company's TSR performance (the "Company TSR") during a three-year performance period (with respect to the Annual Performance RSUs) or a two-year performance period (with respect to the Transition Performance RSUs), in each case commencing on January 1, 2022 (each, a "Performance Period"), as compared to the TSR percentages of the companies included on the FTSE Nareit Lodging/Resort Index that have a minimum equity market capitalization of $500,000,000 (the "Index Relative Performance"). In the event the Index Relative Performance is achieved at the "Threshold," "Target" or "Maximum" level as specified in the applicable award agreement, the award will become vested with respect to the percentage of RSUs as set forth in the chart above.

If the Index Relative Performance falls between the levels specified as Threshold and Target or between the levels specified as Target and Maximum, the percentage of RSUs subject to the Performance RSU Awards that will vest will be determined using straight-line linear interpolation between such levels.

Notwithstanding the foregoing, if Company TSR is negative for the applicable Performance Period, the percentage of RSUs subject to the Performance RSU Awards that vest will be reduced by 25%.

The table below sets forth the Target dollar denominated value and number of shares subject to the Annual Performance RSUs and the Transition Performance RSUs awarded to each NEO in February 2022.

***Dividend Equivalents.*** The Performance RSU Awards and Promotion Performance RSUs were granted in tandem with a corresponding dividend equivalent. Each dividend equivalent entitles the NEO to receive payments equal to the amount of the dividends paid on the share of common stock underlying the RSU to which the dividend equivalent relates. Any dividend equivalent payments that would have been made prior to the date on which the RSU becomes a vested or an Earned RSU (plus or minus the amount of gain or loss on such amounts had they been reinvested in common stock on the date that they were paid) will be paid within 45 days following the date on which the RSU becomes a vested or an Earned RSU. Upon the NEO's termination of service for any reason, the NEO will not be entitled to any dividend equivalent payments with respect to any RSUs that do not become vested or an Earned RSU.

***Benefits and Perquisites*.** Our benefit programs are based on an assessment of competitive market factors, and a determination of what is needed to attract and retain qualified executives. Our primary benefits for executives include participation in our broad-based plans at the same cost and on the same terms as other employees. These plans include a tax qualified 401(k) savings plan (with safe harbor contributions equal to 3% of a participant's pay up to $9,150), additional Company 401(k) contributions, health, dental and vision insurance plans, term life insurance and disability coverage and a matching charitable gift program up to a maximum of $5,000 for each employee. In addition, each of our NEOs receive a maximum reimbursement credit of $5,000 for room and tax expenditures at the Company's hotels and resorts.

The Company does not provide non - qualified deferred compensation or pension benefits to any of its employees, including its NEOs.

***Peer Group Information.*** *The* Compensation Committee uses comparison data from various companies in certain peer groups as a guide in its review and determination of base salaries, annual cash bonuses and annual equity incentive awards for its NEOs. During 2022, the Compensation Committee reviewed peer group data provided by its independent compensation consultant, FPC, in the 2021 FPC Executive Compensation Report, to assist and make informed decisions in its determination regarding compensation for our NEOs for 2022. The Compensation Committee evaluates the Company's performance and determines whether the compensation elements and levels that we provide to our NEOs are generally appropriate relative to the compensation elements and levels provided to their counterparts at our peer companies, in light of our performance relative to our peers and in light of each NEO's contribution to our performance.

*2021 FPC Executive Compensation Report*. In 2022, the Compensation Committee, based on the information provided by the 2021 FPC Executive Compensation Report, determined and monitored the composition of our peer groups. The peer groups selected and used by the Compensation Committee were all public real estate companies

in 2021 and were divided into two groups: hotel REIT peers and size/geographic peers. Each peer group is discussed and identified below:

● Hotel REIT Peer Group. This peer group consisted of 10 public hospitality REITs that the Company and FPC consider to be the most relevant peer group against which to review compensation for NEOs, as they are all lodging-focused, self-managed REITs. This peer group, as of May 31, 2021, had total capitalization ranging from approximately $2.0 billion to $18.5 billion compared to the Company's consolidated total capitalization of $3.7 billion.

● Size/Geographic - Based Peer Group. This peer group consisted of 12 public real estate companies, four of which have corporate headquarters located within the state of California. This peer group focuses on a variety of asset classes, but based on a combination of business focus, size and geography, the companies were viewed by FPC as comparable. This peer group, as of May 31, 2021, had total capitalization ranging from approximately $2.5 billion to $8.9 billion compared to the Company's consolidated total capitalization of $3.7 billion.

&nbsp;&nbsp;&nbsp;&nbsp;(1) We pay a cash incentive bonus for performance under our Incentive Bonus Plan in February following the performance year if the performance criteria related to the Cash Incentive Bonus Objectives have been satisfied in the performance year, with the exception of Mr. Pasquale, whose cash incentive bonus was governed by the terms of his employment agreement with the Company and the Compensation Committee. The actual amounts of the fiscal year 2022 performance cash incentive bonus are shown in the SCT in the "Non – Equity Incentive Plan Compensation" column. The Threshold, Target and Maximum award opportunities shown under this heading are for 2022 performance. For our Current NEOs, the amounts are a multiple of each NEO's base salary in 2022. See "*Compensation Discussion and Analysis—2022 Compensation Decisions (Annual Cash Incentive Bonuses and Annual Equity Incentive Awards)*" for a detailed description of the annual cash incentive bonuses.

2022 GRANTS OF PLAN-BASED AWARDS

&nbsp;&nbsp;&nbsp;&nbsp;(2) The amounts reported in the Estimated Future Payouts Under Equity Incentive Plan Awards column represent the possible number of RSUs that may vest based upon the level of achievement of the applicable performance measures. These estimated possible payouts for each NEO do not include dividend equivalent units that may vest, if at all, following the end of the performance period. See "*Compensation Discussion and Analysis—2022 Compensation Decisions (Annual Cash Incentive Bonuses and Annual Equity Incentive Awards)*" for a detailed description of the Annual Performance RSUs, Transition Performance RSUs and Promotion Performance RSUs.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;a.  ***Annual Performance RSUs*** . The RSUs have a three-year performance period and vest based on the Company's TSR compared to Index Relative Performance. Threshold assumes that 50% of the RSUs awarded vest, Target assumes that 100% of the RSUs awarded vest, and Maximum assumes that 200% of the RSUs awarded vest.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;b.  ***Transition Performance RSUs*** . The RSUs have a two-year performance period and vest based on the Company's TSR compared to Index Relative Performance. Threshold assumes that 50% of the RSUs awarded vest, Target assumes that 100% of the RSUs awarded vest, and Maximum assumes that 200% of the RSUs awarded vest.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;c.  ***Promotion Performance RSUs*** . The RSUs will be deemed Earned RSUs based on the Company's achievement of five share price targets within a five-year performance period. One fifth of the award reported under Target is earned on each date, prior to the fifth anniversary of the grant date, on which the Company achieves average closing share price targets of $13.50, $15.00, $16.50, $18.00 and $19.50 during a 20 consecutive trading day period. Earned RSUs will vest on the later to occur of the date on which the stock price target is achieved or the Promotion Vesting Date.

&nbsp;&nbsp;&nbsp;&nbsp;(3) The amounts in this column represent the number of Time-Based RSAs granted to the NEOs in 2022. See "*Compensation Discussion and Analysis—2022 Compensation Decisions (Annual Cash Incentive Bonuses and Annual Equity Incentive Awards)*" for a detailed description of the Annual Time-Based RSAs, Transition Time-Based RSAs and Promotion Time-Based RSAs and for a discussion of the changes to our equity incentive award program.

&nbsp;&nbsp;&nbsp;&nbsp;(4) The grant date fair value for each of the Time-Based RSAs equals the number of RSAs multiplied by the closing common stock price on the NYSE on the applicable grant date as reported in the table above, computed in accordance with ASC Topic 718. The amount shown for grant date fair value for each of the Performance RSUs is calculated using a Monte Carlo simulation model in accordance with ASC Topic 718. For more information, please see footnote 3 of our SCT in "*Executive Compensation*."

### EMPLOYMENT AGREEMENTS (GIGLIA, REYES, SPRINGER, KLEIN, OSTAPOVICZ AND PASQUALE)

#### Messrs. Giglia, Reyes, Springer, Klein, and Ostapovicz
On August 29, 2022, we entered into amended and restated employment agreements with Messrs. Giglia, Springer, Klein and Ostapovicz in order to reflect each NEO's updated executive officer position and compensation (collectively, the "Amended and Restated Employment Agreements") which amended and restated the existing employment agreements that we had previously entered into with each executive (collectively, as amended, the "Former Employment Agreements"). On August 29, 2022, we also entered into an employment agreement with Mr. Reyes (together with the Amended and Restated Employment Agreements, the "Employment Agreements"). Mr. Reyes was not previously party to an employment agreement with the Company. A summary of the material terms of each Employment Agreement is below.

Each of the Employment Agreements will continue until terminated in accordance with its terms. Each of the Employment Agreements provides for an annual base salary, eligibility to earn an annual cash performance bonus, eligibility to receive an annual equity award and certain severance payments and benefits, each as described more fully below. In addition, each of the NEOs will be eligible to participate in welfare and fringe benefit plans, incentive plans and savings/retirement plans generally available to senior executives of the Company.

The Employment Agreements and the Former Employment Agreements (excluding Mr. Reyes who did not have a Former Employment Agreement) provide for the following 2022 annual base salaries: $550,000 through March 6, 2022 and $600,000 for the remainder of 2022 for Mr. Giglia, $300,000 through March 6, 2022 and $325,000 for the remainder of 2022 for Mr. Reyes, $500,000 through March 6, 2022 and $550,000 for the remainder of 2022 for Mr. Springer, $425,000 for Mr. Klein and $400,000 for Mr. Ostapovicz, all of which may be increased from time to time in the Company's sole discretion as determined by the Compensation Committee. In addition, under the Employment Agreements and the Former Employment Agreements (excluding Mr. Reyes who did not have a Former Employment Agreement), each NEO is eligible to earn an annual cash performance bonus based on the attainment of individual and Company performance objectives as determined by the Compensation Committee with (i) a Threshold level equal to 67.5% of base salary for Messrs.

Pursuant to their respective Employment Agreements, each of the NEOs is eligible to receive severance payments and benefits in the event of certain terminations of his employment described below under "*Potential Payments Upon Termination or Change in Control*." Each Employment Agreement also includes certain restrictive covenants, including non-solicitation and non-disparagement. In connection with entering into the Employment Agreements, each NEO also entered into an indemnification agreement with the Company providing that the Company will indemnify and advance expenses to him in the case of certain claims made against him by virtue of his position with the Company.

#### Mr. Pasquale
Mr. Pasquale served as our Interim CEO pursuant to an employment agreement with us dated September 10, 2021.

Pursuant to their respective Employment Agreements, if the Company terminates the applicable NEO's employment without "cause" or the NEO terminates his employment for "good reason" (each as defined in the applicable NEO's Employment Agreement), then, conditioned upon the NEO's timely execution (and non-revocation) of a general release of claims, the NEO will be entitled to receive (i) a cash severance payment equal to the sum of: (A) two times the sum of: (x) the NEO's annual base salary as in effect on the date of termination, and (y) the greater of the NEO's Target annual bonus for the year in which the termination occurs and the actual annual bonus paid with respect to the last completed calendar year preceding the termination date, (B) any earned but unpaid annual bonus for a prior calendar year, and (C) a pro-rated bonus for the year in which such termination occurs (based on the NEO's Target level bonus), and (ii) Company-paid continued health insurance coverage for himself and his eligible family members for up to 18 months following the termination date. In addition, Company equity awards granted prior to January 1, 2022 will vest to the extent that such awards were scheduled to vest within the 12-month period immediately following the date of termination (or in full if such termination occurs within 12 months following a change in control of the Company), and Company equity awards granted on or after January 1, 2022 that vest solely based on the NEO's continued employment or service will vest and become exercisable in full.

Pursuant to their respective Employment Agreements, if the applicable NEO's employment is terminated by reason of death or "disability", he (or his estate) will be entitled to receive (i) an amount equal to the sum of (A) 100% of his annual base salary then in effect, (B) any earned but unpaid annual bonus for the calendar year preceding the year in which such termination occurs, and (C) a pro-rated bonus for the calendar year in which the death or "disability" occurs (based on the NEO's Target bonus), (ii) accelerated vesting of all outstanding time-based RSA awards, and (iii) Company-paid continued health insurance coverage for himself and/or his eligible family members for up to 18 months following the termination date.

We believe that job security and terminations of employment are causes of significant concern and uncertainty for senior executives and that providing protections to our Current NEOs in these contexts is therefore appropriate in order to alleviate these concerns and allow the executives to remain focused on their duties and responsibilities to our Company in all situations.

#### Mr. Pasquale
In connection with Mr. Pasquale ceasing to serve as Interim CEO, in accordance with Mr. Pasquale's employment agreement with the Company, Mr. Pasquale's RSA award granted to him in September 2021 upon his appointment as Interim CEO vested in full and he received a cash performance bonus in an amount equal to $1,800,000, which was determined by the Compensation Committee based on Mr. Pasquale's performance as Interim CEO. Based on our common stock's closing price on the date of vesting of $11.33 per share, the value of the RSAs that vested upon Mr. Pasquale ceasing to serve as Interim CEO was $2,257,967. Effective September 1, 2022, Mr. Pasquale ceased to serve as Executive Chairman and resumed his role as independent Chairman of the Board on September 2, 2022. We did not pay or provide Mr. Pasquale with severance payments in connection with his ceasing to serve as Executive Chairman.

### PAY RATIO DISCLOSURE
As required by Section 953(b) of the Dodd-Frank Wall Street Reform and Consumer Protection Act, and Item 402(u) of Regulation S - K, we are providing the following information regarding the relationship of the annual total compensation of our employees and the annual total compensation of Bryan A. Giglia, our CEO as of December 31, 2022. The pay ratio specified below is a reasonable estimate calculated in a manner that is intended to be consistent with Item 402(u) of Regulation S - K.

For 2022, our last completed fiscal year:

● the median of the annual total compensation of all of our employees (other than our CEO) was $206,806; and

● the annual total compensation of our CEO was $5,368,985. This amount differs from the amount reported in the "total" column of the SCT as disclosed in "*Executive Compensation*" due to the annualization of Mr. Giglia's compensation for purposes of this Pay Ratio Disclosure.

Based on this information, for 2022, our CEO's annual total compensation was 26.0 times that of the median of the annual total compensation of all of our employees (other than our CEO).

### DETERMINING THE MEDIAN EMPLOYEE
*Employee Population*. We determined that, as of December 31, 2022, our employee population, excluding our CEO, consisted of 39 full-time employees.

*Methodology for Determining Our Median Employee*. To identify the median employee from our employee population, we reviewed the annual total compensation of each of our 39 employees in the same manner as calculated for the annual total compensation of our CEO.

### COMPENSATION MEASURE AND ANNUAL TOTAL COMPENSATION OF MEDIAN EMPLOYEE
With respect to the annual total compensation of the median employee, we identified and calculated the elements of such employee's compensation for 2022 in accordance with the requirements of Item 402(c)(2)(x) of Regulation S-K, resulting in annual total compensation of $206,806.

### ANNUAL TOTAL COMPENSATION OF CEO
In accordance with SEC rules, we elected to use the annualized annual total compensation of our CEO who was serving as our PEO on December 31, 2022. To calculate the annual total compensation paid or provided to Mr. Giglia in the position of PEO, we annualized Mr. Giglia's annual base salary following his appointment as CEO on March 7, 2022 and otherwise used the amounts reported in our 2022 SCT included in the "*Executive Compensation*" section of this Proxy Statement.

Additionally, the Compensation Committee recognized the significant additional time commitment and guidance provided by Mr. Pasquale that goes above and beyond what is typically required by other directors.

During 2021, the Board established the Investment Committee and an ad hoc Search Committee. The Search Committee was created to direct the search for a new CEO and was dissolved following the appointment of Mr. Giglia as CEO in March 2022. The Investment Committee was active for one year and dissolved in September 2022. The Compensation Committee, together with the Board, approved the following compensation structure for these committees:

● $50,000 annual cash retainer paid to the chair of the Investment Committee of the Board.

● $20,000 annual cash retainer paid to each member (other than the chair) of the Investment Committee of the Board.

### INDEPENDENT REVIEW OF DIRECTOR COMPENSATION
The Compensation Committee is responsible for reviewing and making recommendations to the Board on compensation and benefits for the independent directors. The Compensation Committee generally reviews the compensatory arrangement for the independent directors biennially.

*2022 FPC Board Compensation Report*. During the first quarter of 2022, FPC's report detailed the 2020 director compensation programs (as disclosed in the 2021 proxy statements) for two select groups of publicly - traded REITs as of December 31, 2021, comprised of (a) a hotel peer group consisting of 10 companies with implied total capitalizations ranging from approximately $2.0 billion to $18.8 billion and (b) a size/geographic peer group consisting of 12 companies with implied total capitalizations ranging from approximately $2.5 billion to $9.7 billion compared to the Company's consolidated total capitalization of $3.7 billion. Findings from the 2022 FPC Board Compensation Report were used to set the 2022 independent director compensation.

Based on the 2022 FPC report and current market trends, the Compensation Committee recommended that no changes were necessary for the independent directors' compensation for 2022.

### REPORT OF THE AUDIT COMMITTEE OF THE BOARD
*The following report of the Audit Committee does not constitute soliciting material and should not be deemed filed or incorporated by reference into any of Sunstone's filings under the Securities Act of 1933, as amended, or under the Securities Exchange Act of 1934, as amended, except to the extent we specifically incorporate this report by reference.*

The Audit Committee (the "Committee") of the Board of Directors ("Board") of Sunstone Hotel Investors, Inc. ("Sunstone" or the "Company") is composed of three directors, each of whom meet the independence and other requirements of the New York Stock Exchange, and all of whom qualify as "audit committee financial experts" within the meaning of Item 401(e) of Regulation S-K of the Sarbanes-Oxley Act of 2002. The Audit Committee operates under a written charter adopted by the Board that outlines its responsibilities and the practices it follows. You can view the charter in the Corporate Governance section of our website at www.sunstonehotels.com. The Committee reviews and assesses the adequacy of its charter at least annually and, when appropriate, recommends changes to the Board to reflect the evolving role of the Audit Committee.

Management of Sunstone has responsibility for preparing the Company's financial statements, including the Company's internal control over financial reporting. Ernst & Young LLP, acting as independent registered public accountants, is responsible for performing an audit of the Company's annual consolidated financial statements in accordance with generally accepted accounting principles ("GAAP") and for issuing a report on those statements. Ernst & Young LLP also is responsible for auditing Sunstone's effectiveness of internal controls over financial reporting and issuing a report thereon. The Committee is responsible for the integrity of the Company's financial statements and internal control structure on behalf of the Board. The Committee met four times during 2022, including meetings regularly with Ernst & Young LLP and the internal auditor, both privately and with management present. In addition, before each Committee meeting, the Chair of the Committee holds a discussion with the Ernst & Young LLP audit partner.

In fulfilling its oversight responsibilities, the Committee reviewed and discussed with management and Ernst & Young LLP the audited financial statements for the year ended December 31, 2022 as well as the interim financial statements for the periods ended March 31, 2022, June 30, 2022 and September 30, 2022. These reviews included a discussion:

● of critical accounting policies of the Company and potential or planned future changes to accounting standards and any impact their implementation could have on the Company's financial statements;

● of the reasonableness of significant financial reporting estimates and judgments made in connection with the financial statements, including the quality (and not just acceptability) of the Company's accounting policies;

● with the Company's internal and independent auditors of the scope for their respective audits, the results of their respective reviews and their evaluations of the overall quality of the Company's internal controls and financial reporting;

● of the written disclosures and the letter from Ernst & Young LLP that is required by the Public Company Accounting Oversight Board ("PCAOB") regarding the independent accountant's communications with the Audit Committee concerning independence; and

● of the potential effects of regulatory and accounting initiatives on the Company's financial statements.

The Committee has also discussed with the independent auditors the matters required to be discussed under PCAOB Auditing Standard No. 1301, "*Communications with Audit Committees*." In addition, the Committee has received the written disclosures and the letter from the independent accountant required by applicable requirements of the PCAOB regarding the independent accountant's communications with the audit committee concerning independence, and has discussed with the independent auditors the auditors' independence from Sunstone and its management, including the matters in the written disclosures and letter required by applicable requirements of the PCAOB.

REPORT OF THE AUDIT COMMITTEE OF THE BOARD

Among other matters, the Committee also:

● reviewed the level of fees paid relative to fees paid by peers and companies of similar size and geographic location, and engaged the internal and independent auditor and appointed Ernst & Young LLP to serve in the capacity of independent auditor during 2022;

● reviewed Ernst & Young's performance, qualifications, technical expertise, efficiency of services provided, knowledge of the Company operations and industry and quality control procedures in its determination to recommend the retention of Ernst & Young LLP, including reviewing reports on Ernst & Young provided by the PCAOB and reviewing Ernst & Young's performance from the perspective of the members of senior management ;

● reviewed and approved the Company's policy for the pre - approval of audit and permitted non - audit services by the independent auditor and reviewed and approved fees and services;

● consulted with management and Ernst & Young LLP with respect to the Company's processes for risk assessment including meetings between the chair of the Committee and the lead audit partner;

● reviewed significant legal developments which affect or could affect the Company;

● reviewed the Company's cybersecurity policies, procedures and systems in-place to protect the Company's financial and other proprietary data;

● reviewed communications from and management's responses to governmental agencies for matters of material significance;

● reviewed and approved the type and presentation of information, including earnings guidance, to be included in the Company's earnings releases and financial supplemental disclosures; and

● reviewed and responded to any calls placed on the Sunstone Business Conduct and Ethics Line.

Members of the Committee are not full - time employees of Sunstone and are not performing the functions of auditors or accountants. As such, it is not the duty or responsibility of the Committee or its members to conduct "field work" or other types of auditing or accounting reviews or procedures or to set auditor independence standards. Members of the Committee necessarily rely on the information provided to them by management and the independent accountants. Accordingly, the Committee's considerations and discussions referred to above do not ensure that the audit of the Company's financial statements has been carried out in accordance with U.S. GAAP or that the Company's auditors are in fact "independent."

In reliance on the reviews and discussions referred to above, and subject to the limitations on the role and responsibilities of the Committee referred to above and in the Committee charter, the Committee recommended to the Board the inclusion of the audited financial statements in Sunstone's 2022 Annual Report on Form 10 - K for filing with the Securities and Exchange Commission.

### STOCKHOLDER PROPOSALS FOR THE 2024 ANNUAL MEETING
Stockholder proposals intended to be presented at the 2024 Annual Meeting pursuant to SEC Rule 14a-8 must be received by the Secretary of Sunstone no later than 5:00 p.m. Pacific Time on November 23, 2023, to be considered for inclusion in our proxy statement and proxy card relating to the 2024 Annual Meeting. In addition, any stockholder who wishes to propose a nominee to the Board or submit any other matter to a vote at the 2024 Annual Meeting (other than a stockholder proposal included in our proxy materials pursuant to SEC Rule 14a-8) must deliver such information to our Secretary no earlier than October 24, 2023 and no later than 5:00 p.m. Pacific Time on November 23, 2023 and must comply with the other provisions and requirements of Article II, Section 2.11 of our then current bylaws, which are on file with the SEC and may be obtained from our Secretary upon request. Additionally, any stockholder who wishes to propose a nominee to the Board for inclusion in our proxy materials for the 2024 Annual Meeting pursuant to our proxy access bylaw must deliver such information to our Secretary no earlier than October 24, 2023 and no later than 5:00 p.m. Pacific Time on November 23, 2023 and must comply with the other provisions and requirements of Article II, Section 2.16 of our then current bylaws, which are on file with the SEC and may be obtained from our Secretary upon request. In addition to satisfying the foregoing requirements under the company's bylaws, to comply with the universal proxy rules, stockholders who intend to solicit proxies in support of director nominees other than the Company's nominees must provide notice that sets forth the information required by Rule 14a-19 under the Exchange Act no later than March 5, 2024.

We intend to file the Proxy Statement and a white proxy card with the SEC in connection with our solicitation of proxies for our 2024 Annual Meeting of Stockholders. Stockholders may obtain the Proxy Statement (and any amendments and supplements thereto) and other documents as and when filed by the Company with the SEC without charge from the SEC's website at: *www.sec.gov*.

### DELINQUENT SECTION 16(a) REPORTS
Section 16(a) of the Exchange Act requires our directors, executive officers, and all persons who beneficially own more than 10% of the outstanding shares of our common stock to file reports of holdings and ownership changes with the SEC. Based solely on our review of the copies of such reports furnished to us, we believe that during 2022 all applicable filing requirements of our directors, executive officers and 10% beneficial owners were made on a timely basis, except for a Form 4 for Robert C. Springer, dated June 13, 2022, which reported the uninstructed and inadvertent disposition of 0.9581 of a share of Sunstone common stock on June 3, 2022, which was filed late as a result of a late notice of the uninstructed sale of a fractional share.

### HOUSEHOLDING OF PROXY MATERIALS
The SEC has adopted rules that permit companies and intermediaries (e.g., brokers) to satisfy the delivery requirements with respect to two or more stockholders sharing the same address by delivering a single Proxy Statement, Annual Report or Notice Card, as applicable, addressed to those stockholders. This process, which is commonly referred to as "householding," potentially means extra convenience for stockholders and cost savings for companies. A number of brokers with account holders who are stockholders may be householding the Company's proxy materials. If you receive a householding notification from your broker, a single set of proxy materials will be delivered to multiple stockholders sharing an address unless contrary instructions have been received by your broker. Once you receive notice from your broker that they will be householding communications to your address, householding will continue until you are notified otherwise. Stockholders who currently receive multiple copies of the proxy materials at their address and would like to request householding of their communications should contact their broker. In addition, if you receive a householding notification and wish to receive a separate Proxy Statement, Annual Report or Notice Card, as applicable, at your address, you should also contact your broker directly.

If you wish to receive a separate set of proxy materials for the 2023 Annual Meeting, we will deliver them promptly upon request sent to Sunstone Hotel Investors, Inc., 15 Enterprise, Suite 200, Aliso Viejo, California 92656, Attention: Secretary.

### OTHER MATTERS TO COME BEFORE THE ANNUAL MEETING
The Board knows of no other matters to be presented for stockholder action at the Annual Meeting. If any other matters are properly presented at the meeting for action, it is intended that the persons named in the proxies will vote upon such matters in accordance with their discretion.

### COMPENSATION COMMITTEE INTERLOCKS AND INSIDER PARTICIPATION
During all or portions of 2022, W. Blake Baird, Andrew Batinovich, Monica S. Digilio, and Kristina M. Leslie served on our Compensation Committee. None of the members of our Compensation Committee is or has been a former or current executive officer or employee of the Company. During 2022, no member of the Compensation Committee had a relationship that must be described under the SEC rules relating to disclosure of related person transactions.

Mr. Pasquale currently serves as Lead Independent Director on the board of directors of Terreno Realty Corporation. He served as a member of Terreno Realty Corporation's compensation committee commencing on September 2, 2022 after he resumed his role of independent Chairman of the Board for the Company. Mr. Baird serves as Chairman of the Board and Chief Executive Officer of Terreno Realty Corporation. Mr. Baird joined as a member of Sunstone's Compensation Committee on September 2, 2022. Mr. Pasquale was not a member of the compensation committee of Terreno Realty Corporation, nor was Mr. Baird a member of the Company's Compensation Committee, during the period in which Mr. Pasquale served as our Interim CEO or Executive Chairman. None of our other executive officers served as a director or member of a compensation committee (or other committee serving an equivalent function) of any other entity whose executive officers served as a director or member of our Compensation Committee during the fiscal year ended December 31, 2022.

### OTHER INFORMATION
Sunstone will pay the cost of its proxy solicitation. We also expect that some of our employees may solicit Sunstone stockholders personally and by telephone. None of these employees will receive any additional or special compensation for doing this. We may engage the services of a proxy solicitation firm to assist in the solicitation of proxies.
