EXPLANATORY NOTE

This proxy statement supplement (this “Supplement”) supplements and amends the definitive proxy statement on Schedule 14A filed with the Securities and Exchange Commission by Service Properties Trust, a Maryland real estate investment trust (the “Company,” “we,” “us” or “our”) on March 17, 2026 and as amended on March 25, 2026 (the “Proxy Statement”).

We are filing this Supplement to amend the Proxy Statement and the Proxy Card to add a new Proposal 4 seeking shareholder approval of the Third Amended and Restated 2012 Equity Compensation Plan (the “Amended and Restated Plan”). The Amended and Restated Plan increases the number of Common Shares available under the Second Amended and Restated 2012 Equity Compensation Plan (the “Predecessor Share Award Plan”) from 6,100,000 previously reserved under the Predecessor Share Award Plan to an aggregate of 10,100,000.

Approval of the Third Amended and Restated Plan requires the affirmative vote of a majority of all the votes cast, in person or by proxy, at our 2026 Annual Meeting. Abstentions and broker non-votes (i.e., shares held by brokers or nominees as to which (i) instructions have not been received from the beneficial owner or the persons entitled to vote and (ii) the broker does not have discretionary voting power on a particular matter), if any, are included in determining whether a quorum is present. Abstentions are not votes cast and, therefore, will not be included in vote totals and will have no effect on the outcome of new Proposal 4. Broker non-votes are not votes cast and, therefore, will not be included in vote totals and will have no effect on the outcome of new Proposal 4. You may vote “FOR,” “AGAINST” or “ABSTAIN” on new Proposal 4.

Except for the new Proposal 4, the amended Notice of Annual Meeting and the amended Proxy Card, this Supplement does not otherwise modify or update any other disclosures presented in the Proxy Statement. This Supplement should be reviewed in conjunction with the Proxy Statement and, from and after the date of this Supplement, any references to the “Proxy Statement” shall be deemed to include the Proxy Statement as amended by this Supplement. In addition, this Supplement does not reflect events occurring after the date of the Proxy Statement or modify or update disclosures that may have been affected by subsequent events. All page references are to the Proxy Statement, and capitalized terms used but not otherwise defined herein have the meanings ascribed to such terms in the Proxy Statement.

The amended Proxy Card differs from the original Proxy Card previously furnished to you in that the amended Proxy Card includes new Proposal 4. If you have already voted, we encourage you to resubmit your vote on all proposals by submitting the amended Proxy Card or by submitting a proxy via telephone or the Internet by following the instructions included in the Proxy Statement and the procedures in your amended Proxy Card. However, if you return or have returned an original Proxy Card, your proxy will remain valid for all other proposals and will be voted at the 2026 Annual Meeting unless revoked. PLEASE NOTE THAT IF YOU SUBMIT AN AMENDED PROXY CARD IT WILL REVOKE ALL PRIOR PROXY CARDS SO IT IS IMPORTANT TO INDICATE YOUR VOTE ON EACH PROPOSAL ON THE AMENDED PROXY CARD.

PROPOSAL 4:

APPROVAL OF THE THIRD AMENDED AND RESTATED 2012 EQUITY COMPENSATION PLAN

We are asking shareholders to approve the Third Amended and Restated 2012 Equity Compensation Plan (the “Amended and Restated Plan”). The Amended and Restated Plan increases the number of Common Shares available under the plan from the 6,100,000 previously reserved under the predecessor Second Amended and Restated 2012 Equity Compensation Plan, as amended (the “Predecessor Share Award Plan”), to an aggregate of 10,100,000, adopts an annual limit of $500,000 on the aggregate grant-date fair value of Common Shares that may be granted to any Trustee and extends the term of the plan until the tenth anniversary of our 2026 Annual Meeting.

Background

The Amended and Restated Plan provides that an aggregate of 10,100,000 Common Shares are available for award under the plan pursuant to grants of Common Shares or Common Shares subject to restrictions (“Restricted Shares”). As of April 20, 2026, there were 645,578,088 Common Shares outstanding (not including unvested Restricted Shares), 1,664,727 Common Shares were available for grants of future awards pursuant to the Predecessor Share Award Plan, and there were 1,639,071 unvested Restricted Shares outstanding, which remain subject to possible forfeiture to, or repurchase for nominal consideration by, us as provided in applicable share award agreements.

Purpose of the Amended and Restated Plan

Following a review of our equity compensation plan, we have determined that the number of Common Shares available under the Predecessor Share Award Plan is insufficient to meet our anticipated annual equity awards to our Trustees, executive officers and other employees of our manager, The RMR Group LLC (“RMR”), and others who provide services to us (collectively, the “Eligible Individuals”), over the next two years. The Amended and Restated Plan will allow us to continue to grant equity based compensation to the Eligible Individuals, which our Board of Trustees (our “Board”) believes supports our compensation strategy to increase the percentage of total compensation that is made up of equity awards to further align management and shareholders. Our Board believes that equity based compensation recognizes our executive officers’ and other RMR employees’ and service providers’ scope of responsibilities, rewards demonstrated performance and leadership, motivates future performance and further aligns the interests of these individuals with the long term interests of our shareholders.

The Amended and Restated Plan, if approved, will be the only plan we have to provide equity based incentive compensation to our Trustees, executive officers and other service providers. If our shareholders do not approve the Amended and Restated Plan, our and RMR’s ability to attract and retain Trustees and employees may be negatively impacted, which could have an impact on our long term success.

Historic Share Usage Information

In connection with the drafting of the proposed Amended and Restated Equity Plan, the Compensation Committee of our Board (the “Compensation Committee”) received guidance on plan design and sizing from Ferguson Partners Consulting (“FPC”), an independent compensation consultant retained by the Company.

This analysis included a consideration of the following key factors:

Shares Available for Issuance. As of April 20, 2026, there were 645,578,088 Common Shares outstanding (not including unvested Restricted Shares), 1,664,727 Common Shares were available for grants of future awards pursuant to the Predecessor Share Award Plan, and there were 1,639,071 unvested Restricted Shares

2026 Proxy Statement

outstanding, which remain subject to possible forfeiture to, or repurchase for nominal consideration by, us as provided in applicable share award agreements.

Reasonable Share Reserve. In determining the share reserve under the Amended and Restated Plan, our Board reviewed the Compensation Committee’s recommendations, which were based in part on the information and analysis prepared by FPC. Among other things, the Compensation Committee considered the potential dilutive effect of a share reserve increase both prior to, and following, our recent public equity offering, which was completed subsequent to the filing of our Proxy Statement, and determined that the requested additional 4,000,000 Common Shares would not have a substantially dilutive effect in either case (2.4% of Common Shares outstanding as of the Record Date and 0.6% of Common Shares outstanding as of April 20, 2026).

Historical Burn Rate. Our historical burn rate is equal to the number of Common Shares subject to equity awards granted during a period, in proportion to our weighted average outstanding Common Shares. Our three-year average burn rate is 0.65%, which is well below market benchmarks.

Year	Time-Based Full-Value Awards Granted		Weighted Average Common Shares Outstanding		Burn Rate
2025		1,747,861		165,951,000	1.05%
2024		1,031,329		165,338,000	0.62%
2023		438,000		164,988,000	0.27%
			3-Year Average		0.65%

Overhang. Our overhang is the number of outstanding Common Shares that are subject to vesting requirements at year end (i.e., unvested Restricted Shares) plus the number of Common Shares available for future grants of equity awards, inclusive of an additional 4,000,000 Common Shares, assuming approval of the Amended and Restated Plan, in proportion to our Common Shares outstanding at year end excluding the unvested Restricted Shares. As of the year ended December 31, 2025, our overhang was 4.42%, which includes the number of Common Shares available for future grants (3.40%) and the number of unvested Restricted Shares (1.02%).

Material Terms of the Amended and Restated Plan

A copy of the Amended and Restated Plan is set forth as Annex A to this Proxy Statement Supplement. The material features of the Amended and Restated Plan are described below. The following description is intended to be a summary, and does not purport to be a complete statement of the terms of the Amended and Restated Plan. Accordingly, this summary is qualified in its entirety by reference to Annex A.

Administration. The Amended and Restated Plan will continue to be administered by our Board or, in the discretion of our Board, a committee designated by our Board and comprised of at least two members of our Board. Our Board has delegated its authority to administer the Predecessor Share Award Plan to the Compensation Committee and such delegation is expected to remain in place with respect to the Amended and Restated Plan; however, our Board may revoke or rescind such delegations of authority in whole or in part at any time. Each member of any committee administering the Amended and Restated Plan is required to be a “non-employee director” (within the meaning of Rule 16b-3 promulgated under Section 16 of the Exchange Act) and to meet such other requirements as our Board may determine to be necessary or appropriate. Our Board or a committee thereof has the authority to administer the Amended and Restated Plan, including the authority to interpret the plan, to make awards thereunder (and determine the terms of such awards) and to adopt and approve from time to time the forms of share award agreements under the Amended and Restated Plan.

Awards. The Amended and Restated Plan permits discretionary awards of Common Shares, which will be subject to such terms and conditions as our Board or a committee may determine, which may include, without limitation, terms with respect to vesting, forfeiture, repurchase and transfer restrictions, typically based on continued employment or service. If it determines to do so, our Board or the designated committee may award shares under the Amended and Restated Plan that are not subject to vesting, forfeiture, repurchase and transfer restrictions (“Unrestricted Shares”); provided that no more than 25% of any individual award may

2026 Proxy Statement

consist of Unrestricted Shares at grant, other than awards of Common Shares to our Trustees that may constitute Unrestricted Shares in their entirety. No Trustee or officer of the Company may be granted more than 1,000,000 Common Shares under the Amended and Restated Plan, and no Trustee may be granted Common Shares under the Amended and Restated Plan with a grant-date fair value greater than $500,000 in any one of the Company’s fiscal years.

Participants. The Amended and Restated Plan permits awards to be made to our Trustees, executive officers and other employees of RMR, as well as consultants, advisors or other persons or entities providing management, administrative or other services to us or to our subsidiaries. Actual participants are determined by our Compensation Committee in its discretion. As of April 20, 2026, we had two executive officers and seven Trustees, and RMR and its subsidiaries had approximately 830 employees who were not either executive officers or Trustees of the Company; all of those persons and other qualifying service providers of the Company would be eligible for awards under the Amended and Restated Plan. During 2025, 114 eligible Trustees, officers, employees of RMR and other persons providing services to us (or our subsidiaries) received awards under the Predecessor Share Award Plan.

Change in Control; Termination Event. The Amended and Restated Plan provides that if we are subject to a “Change in Control” or a “Termination Event” (each as defined in the Amended and Restated Plan) unvested awards will vest upon the occurrence of such event.

Amendment and Termination. The Amended and Restated Plan may be amended or terminated by our Board, subject to shareholder approval where required by law or applicable listing requirements. The Amended and Restated Plan will, unless terminated earlier by our Board, terminate on the tenth anniversary of our 2026 Annual Meeting. However, awards made before the termination of the Amended and Restated Plan may extend beyond that date in accordance with their terms.

Common Shares Available. The total number of Common Shares that may be granted under the Amended and Restated Plan is 10,100,000, which number will be reduced by any shares that have been or may be issued prior to the effective date of the Amended and Restated Plan, subject to adjustment for certain transactions as set forth in the plan. If any Common Shares subject to an award (including awards granted under the Predecessor Share Award Plan, of which there were unvested awards of 1,639,071 shares outstanding as of April 20, 2026) are forfeited, cancelled, repurchased or surrendered, the shares with respect to such award will, to the extent of any such forfeiture, cancellation, repurchase or surrender, again be available for awards under the plan. Common Shares surrendered or withheld as payment of withholding taxes in respect of an award shall not be available again for grant under the Amended and Restated Plan. The number of Common Shares reserved for issuance under the Amended and Restated Plan and the awards made under the plan are generally subject to adjustment by our Board upon the occurrence of a merger, sale of assets, reorganization, recapitalization, exchange of shares, stock split, combination of shares or dividend payable in shares or other securities or any similar corporate transaction.

On April 24, 2026, the last reported sale price of the Common Shares on the Nasdaq was $1.54 per share.

Awards under the Amended and Restated Plan will generally be made in the discretion of our Board or designated committee thereof and are therefore not determinable at this time.

Certain Federal Income Tax Consequences in Respect of the Amended and Restated Plan

The following is a summary of certain United States federal income tax consequences with respect to awards under the Amended and Restated Plan. Participants should consult with their own tax advisors and should not rely upon this summary.

Share Awards. A participant in the Amended and Restated Plan receiving an unrestricted Common Share award (or the unrestricted portion of a Restricted Share award) will be taxed as ordinary compensation income in an amount equal to the fair market value of the Common Shares at the time of the award.

Restricted Shares. The term “restricted shares” refers to an award of Common Shares under the Amended and Restated Plan that are subject to forfeiture restrictions. A participant generally will not be taxed upon the receipt of a Restricted Share award, but rather will recognize ordinary compensation income in an amount

2026 Proxy Statement

equal to the fair market value of the Common Shares at the time the Common Shares are no longer subject to a substantial risk of forfeiture, as defined in the Internal Revenue Code. A participant may, however, elect under Internal Revenue Code Section 83(b) and not later than 30 days after the transfer of such Common Shares to the participant to recognize ordinary compensation income at the time the Restricted Shares are awarded in an amount equal to the fair market value at that time, notwithstanding the fact that such Common Shares are subject to restrictions and a substantial risk of forfeiture. If such an election is made, no additional income will be recognized by such participant at the time the restrictions lapse. However, if Common Shares subject to a Section 83(b) election are later forfeited, no tax deduction is allowable with respect to the previously recognized ordinary compensation income to the participant for the forfeited Common Shares.

The full amount of dividends or other distributions of property made with respect to Restricted Shares before the lapse of any applicable restrictions will constitute ordinary compensation income, unless a Section 83(b) election has been made.

Company Deductions. The Company, as the recipient of the services rendered by the participant, will generally be entitled to a deduction at the same time as and in the same amount that the participant recognizes ordinary compensation income. The Company deductions referred to in this summary may be limited by Internal Revenue Code Section 162(m) for certain employees.

Share Usage

The annual share usage under the Predecessor Share Award Plan for the last three calendar years was as follows:

Year	Awards Granted (number of shares)		Weighted Average Common Shares Outstanding
2025		1,747,861		165,951,000
2024		1,031,329		165,338,000
2023		438,000		164,988,000

Equity Plan Information

We may award Common Shares under the Amended and Restated Plan to our Trustees, executive officers and other employees of RMR, and other individuals who provide services to us or to our subsidiaries. In fiscal year 2025, we issued 1,747,861 Common Shares to our Trustees and officers, employees of RMR and others who provide services to us or to our subsidiaries.

If any Shares subject to an award under the Plan (including prior to the Effective Date) are forfeited, cancelled, repurchased or surrendered, the Shares with respect to such award shall, to the extent of any such forfeiture, cancellation, repurchase or surrender, again be available for awards under the Plan.

Shares may be imprinted with a legend to the effect that the Shares represented may not be sold, exchanged, transferred, pledged, hypothecated or otherwise disposed of except in accordance with the terms of the Securities Act and the applicable Share Agreement, if any. In the event that the Shares are not represented by a certificate, the Company shall direct the Company’s registrar and transfer agent to make an appropriate notation of the restrictions on transfer to which the Shares are subject in the stock books and records of the Company. In addition, the Company may hold the certificates representing Shares pending lapse of any applicable vesting, forfeiture, repurchase, transfer or similar restrictions.

IV.

METHOD OF GRANTING SHARES

Grants of Shares to any Key Person shall be made by action of the Board, which shall have the sole discretion to select persons to whom Shares are to be granted, the amount and timing of each such grant, the extent, if any, to which vesting restrictions or other conditions (which may include repurchase rights) shall apply to the award and all other terms and conditions of any award (which terms and conditions need not be the same as between recipients or awards). If a person to whom such a grant of Shares has been made fails to execute and deliver to the Company a Share Agreement within ten (10) days after it is submitted to him or her, the grant of Shares related to such Share Agreement may be cancelled by the Company, acting by the Board, at its option and in its discretion without further notice to the Participant. No Trustee or officer of the Company may be granted more than 1,000,000 Shares under the Plan after the Effective Date, and no Trustee may be granted Shares under the Plan with a grant-date fair value (as determined for accounting purposes by the Board or, in the discretion of the Board, a committee designated by the Board to administer the Plan) greater than $500,000 in any one of the Company’s fiscal years. Nothing in this Section IV shall prevent the Board from delegating its authority to make grants to a committee pursuant to Section V. No agreement is required to be executed in respect of awards of vested Shares.

ADMINISTRATION OF THE PLAN

The Plan shall be administered by the Board or, in the discretion of the Board, a committee designated by the Board and composed of at least two (2) members of the Board. All references in the Plan to the Board shall be understood to refer to such committee or the Board, whichever shall be administering the Plan from time to time. All questions of interpretation and application of the Plan and of grants of Shares shall be determined by the Board in its sole discretion and the Board shall have the authority to do all things necessary to carry out the purposes of the Plan, and its determinations shall be final and binding upon all persons, including the Company and all Participants. Without limiting the generality of the foregoing, the Board is authorized to (i) adopt and approve from time to time the forms and, subject to the terms of the Plan, the terms and conditions of any Share Agreement; (ii) make adjustments to awards in response to changes in applicable laws, regulations, or accounting principles; and (iii) prescribe, amend and rescind rules and regulations relating to the Plan. If it determines to do so, the Board may grant Shares under this Plan that are not subject to vesting, forfeiture, repurchase and transfer restrictions (“Unrestricted Shares”); provided that no more than 25% of any individual award may consist of Unrestricted Shares at grant, other than awards of Common Shares to our Trustees that may constitute Unrestricted Shares in their entirety.

For so long as Section 16 of the Exchange Act is applicable to the Company, each member of any committee designated to administer the Plan shall qualify as a “non-employee director” within the meaning of Rule 16b-3 under the Exchange Act and shall meet such other requirements as the Board may determine to be necessary or appropriate.

With respect to persons subject to Section 16 of the Exchange Act (“Insiders”) with respect to the Company, transactions under the Plan are intended to comply with all applicable conditions of Rule 16b-3 or its successor under the Exchange Act.

VI.

ELIGIBLE PERSONS

The persons eligible to receive grants of Shares shall be those persons selected by the Board in its discretion from among Key Persons who contribute to the business of the Company and its subsidiaries.

VII.

CHANGES IN CAPITAL STRUCTURE

In the event of any stock dividend or other similar distribution (whether in the form of stock or other securities), stock split or combination of shares (including a reverse stock split), conversion, reorganization, consolidation,

A-2

2026 Proxy Statement

split-up, spin-off, combination, merger, exchange of stock, extraordinary cash dividend or other similar transaction or event, the Board shall make adjustments to the maximum number of Shares that may be issued under the Plan under Article III and Article IV and shall also make appropriate adjustments to the number and kind of shares of stock, securities or other property (including cash) subject to awards then outstanding under the Plan affected by such change and to the other terms and conditions of such awards. No fractional Shares shall be issued pursuant to any such adjustment, and any fractions resulting from any such adjustment shall be eliminated in each case by rounding downward to the nearest whole Share.

VIII.

EFFECTIVE DATE, DURATION, AMENDMENT AND TERMINATION OF PLAN

The Plan shall be effective at the close of business on June 11, 2026 (the “Effective Date”), subject to its approval by the Company’s shareholders. Shares may be granted under the Plan from time to time until the close of business on the tenth anniversary of the Effective Date. Awards outstanding at Plan termination shall remain in effect according to their terms and the provisions of the Plan. The Board hereafter may at any time amend or terminate the terms of an award or the Plan in any respect, provided that (without limiting Article VII hereof) the Board may not, without the affected Participant’s consent, amend or terminate the terms of an award or the Plan so as to affect adversely the Participant’s rights under an outstanding award. Any amendments to the Plan shall be conditioned upon shareholder approval only to the extent, if any, such approval is required by applicable law or listing requirements.

IX.

MISCELLANEOUS

Nonassignability of Shares. Shares subject to a Share Agreement shall not be assignable or transferable by a Participant except in accordance with the terms of the applicable Share Agreement or as may be permitted by the Board.

No Guarantee of Employment. Neither the award of Shares nor a Share Agreement shall give any person the right to continue in the employment or service of, or to continue to act as an officer or, Trustee of, or to serve in any other capacity with, the Company, any subsidiary or the Manager.

Tax Withholding; Section 409A. To the extent required by law, the Company shall withhold or cause to be withheld income and other taxes incurred by a Participant by reason of a grant of Shares, and, as a condition to the receipt of any grant of Shares, a Participant agrees that if the amount payable to him or her by the Company in the ordinary course is insufficient to pay such taxes, he or she shall, upon request of the Company, pay the Company an amount sufficient to satisfy its tax withholding obligations.

Without limiting the foregoing, the Board may in its discretion permit any Participant’s withholding obligation to be paid in whole or in part in the form of Shares, by withholding from the Shares to be issued to such Participant or by accepting delivery of Shares already owned by him or her. The fair market value of the Shares for this purpose shall be the closing price of the Shares on the principal securities exchange on which the Shares are listed on the date such Shares are repurchased by the Company, unless otherwise determined by the Board in its discretion.

If payment of withholding taxes is made in whole or in part in Shares, the Participant shall deliver to the Company share certificates registered in his or her name or other evidence of legal and beneficial ownership of Shares owned by him or her, fully vested and free of all liens, claims and encumbrances of every kind, duly endorsed or accompanied by stock powers duly endorsed by the record holder of the Shares represented by such share certificates. The Compensation Committee may approve comparable procedures to those set forth in the preceding sentence in the event of shares held in book-entry form. If the Participant is subject to Section 16(a) of the Exchange Act, his or her ability to pay the withholding obligation in the form of Shares shall be subject to such additional restrictions as may be necessary to avoid any transaction that might give rise to liability under Section 16(b) of the Exchange Act.

It is intended that awards granted under the Plan be exempt from the application of Section 409A of the Internal Revenue Code of 1986, as amended from time to time, and the Plan and such awards shall be construed in accordance with that intention.

2026 Proxy Statement

A-3

Conditions to Issuance. The issuance of Shares under the Plan is subject to compliance with (1) the laws, rules and regulations of all public agencies and authorities applicable to the issuance and distribution of Shares and (2) the listing rules of any stock exchange or national market system on which the Shares are listed.

No Fractional Shares. No fractional Shares shall be issued or delivered pursuant to the Plan. The Board shall determine whether cash, other Awards, or other property shall be issued or paid in lieu of such fractional Shares or whether such fractional shares or any rights thereto shall be forfeited or otherwise eliminated.

Governing Law. The Plan shall be governed by and construed and enforced in accordance with the laws of the State of Maryland applicable to contracts made and to be performed therein, without reference to the conflicts of law principles thereof.

Change in Control. Each unvested Share under the Plan immediately prior to the occurrence of a “Change in Control” or a “Termination Event” shall become fully vested upon the occurrence of the Change in Control or Termination Event, as each term is defined below.

A “Change in Control” shall be deemed to have occurred if any of the events set forth in any one of the following paragraphs shall have occurred:
