PART I

ITEM 1. BUSINESS

Organization and Background

Mills Music Trust (the “Trust”) was created by a Declaration of Trust, dated December 3, 1964 (the “Declaration of Trust”), for the purpose of acquiring from Mills Music, Inc. (“Old Mills”) the right to receive payment of a deferred contingent purchase price obligation (the “Contingent Portion”) payable to Old Mills. The obligation to pay the Contingent Portion arose as the result of the sale by Old Mills of its music and lyric copyright catalogue (the “Catalogue”) to a newly formed company pursuant to an asset purchase agreement dated December 5, 1964 (the “Asset Purchase Agreement”). Pursuant to the Asset Purchase Agreement, payment of the Contingent Portion to the Trust continues until the end of the year in which the last copyright in the Catalogue expires and cannot be renewed.

The Contingent Portion amounts are currently payable by EMI Mills Music Inc. (“EMI”), the owner of the copyrighted materials contained in the Catalogue. The Trust has been advised that Sony/ATV Music Publishing LLC (“Sony/ATV”) is the administrator and manager of EMI and the Catalogue.

HSBC Bank, USA, N.A. is the Corporate Trustee of the Trust (the “Corporate Trustee”) and Lee Eastman is the Individual Trustee of the Trust (the “Individual Trustee” and together with the Corporate Trustee, the “Trustees”).

Proceeds from Contingent Portion Payments

The Trust receives quarterly payments of the Contingent Portion from EMI and distributes the amounts it receives to the registered owners of Trust certificates (the “Unit Holders”) representing interests in the Trust (the “Trust Units”), after payment of, or withholdings in connection with, expenses and liabilities of the Trust. The Declaration of Trust provides that these are the Trust’s sole responsibilities and that the Trust is prohibited from engaging in any business activities.

Payments of the Contingent Portion to the Trust are based on royalty income which the Catalogue generates. The Trust does not own the Catalogue or any copyrights or other intellectual property rights and is not responsible for collecting royalties in connection with the Catalogue. As the current owner and administrator of the Catalogue, EMI is obligated under the Asset Purchase Agreement to use its best efforts to collect all royalties, domestic and foreign, in connection with the Catalogue and to remit a portion of its royalty income to the Trust as its Contingent Portion payment obligation, in accordance with the terms of the Asset Purchase Agreement.

Calculation of the Contingent Portion

The amount of each payment of the Contingent Portion is based on a formula set forth in the Asset Purchase Agreement. For information regarding the calculation of the Contingent Portion and a related dispute between EMI and the Trust see “Contingent Portion Payments” under Part II, Item 7, “Management’s Discussion and Analysis of Financial Condition and Results of Operations”.

Cash Distributions to Unit Holders

The Declaration of Trust provides for the distribution to the Unit Holders of all funds the Trust receives after payment of, or withholdings in connection with, expenses and liabilities of the Trust.

The Copyright Catalogue

The Catalogue is estimated to be composed of over 12,000 music titles (the “Copyrighted Songs”), of which approximately 1,430 produced royalty income in recent years. Based on information which EMI provided to the Trust, most of the royalty income generated by the Catalogue during recent years has been produced by a relatively small number of the Copyrighted Songs with copyrights established primarily in or prior to 1954.

EMI has provided the Trust with a listing (the “Listing”) of the top 50 earning songs in the Catalogue during the 2025 calendar year (the “Top 50 Songs”). The totals contained in the right most column of the Listing represent gross royalty payments EMI received for each of the Top 50 Songs, before it made deductions in accordance with the Asset Purchase Agreement. The Listing also contains the following additional information for each song title: the writer(s), the original copyright date and copyright renewal date and the date on which each copyright enters the public domain in the United States.

The Listing is set forth below in the form that EMI provided to the Trust. There can be no assurance that the Listing is indicative of the future performance of the Copyrighted Songs or that EMI will be able to retain its rights to the Copyrighted Songs during their full term of copyright protection. As of the date of this report, the Trust has not undertaken an audit to confirm the accuracy of the information contained in the Listing, and there can be no assurance by the Trust that the information EMI provided in the Listing is correct.

Accounting Policies

EMI typically makes payments to the Trust of the Contingent Portion in March, June, September and December for the prior calendar quarter. The payments received are accounted for on a cash basis, as are expenses of the Trust. The Declaration of Trust provides for the distribution to the Unit Holders of the amounts received by the Trust in Contingent Portion payments after payment of, or withholdings in connection with, expenses and liabilities of the Trust.

The Trust’s financial statements reflect only cash transactions and do not include transactions that would be recorded in financial statements presented on the accrual basis of accounting, as contemplated by generally accepted accounting principles in the United States. The Trust does not prepare a balance sheet or a statement of cash flows.

ITEM 1A. RISK FACTORS

The Trust is a smaller reporting company as defined by Rule 12b-2 of the Exchange Act and is not required to provide the information under this item.

ITEM 1B. UNRESOLVED STAFF COMMENTS

None.

ITEM 1C. CYBERSECURITY

The Trust does not have any material internal operations of its own that face material cybersecurity threats and is not a regulated financial institution subject to mandatory cybersecurity compliance under New York law (including, without limitation, the New York Code, Rules and Regulations), and therefore has not adopted any cybersecurity risk management program or formal processes for assessing or monitoring cybersecurity risk. However, the Trust does depend on the digital technologies of the Corporate Trustee and third parties, including EMI, Sony/ATV and their respective affiliates’ information systems, infrastructure and cloud applications and services. Any sophisticated and deliberate attacks on, or security breaches in, the systems, infrastructure or cloud that benefit the Trust, including those of the Corporate Trustee and third parties, could lead to corruption, misappropriation or miscalculation of the gross royalty income arising from the Catalogue (or calculation of the Contingent Portion related thereto) and/or the Trust’s assets, proprietary information and sensitive or confidential data. Because of the Trust’s reliance on the technologies of the Corporate Trustee and third parties including EMI, Sony/ATV, their respective affiliates, the Trust also depends upon the personnel and the processes of such parties to protect against cybersecurity threats arising from their own operations in the ordinary course of their respective businesses. The Trust does not employ any operating personnel and has not contracted for the development of processes of its own for the purpose of data security protections and as such may not adequately protect against, or investigate and/or remediate any vulnerability to, cyber incidents. To the best knowledge of the Trustees, as of December 31, 2025, risks from cybersecurity threats, including any previous cybersecurity incidents, have not materially affected the Trust, but it is possible that any of these occurrences, or a combination of them, could have material adverse consequences on the Trust, including its results of operations or financial condition.

ITEM 2. PROPERTIES

The Trust does not own any property. The administrative office of the Trust is located at the offices of the Corporate Trustee, HSBC Bank, USA, N.A., Corporate Trust Issuer Services, 66 Hudson Boulevard East, New York, New York 10001. Except for fees paid to

the Corporate Trustee in accordance with the Declaration of Trust, no expense is being charged or paid by the Trust for the office space and office equipment of the Corporate Trustee that is being utilized for the Trust. See Note 3, “Related Party Transactions,” under Part II, Item 8, “Financial Statements and Supplementary Data” for information regarding payments by the Trust to the Trustees.

ITEM 6. [RESERVED]

ITEM 7. MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

The Copyright Catalogue

The Catalogue is estimated to be composed of over 12,000 music titles (the “Copyrighted Songs”), of which approximately 1,430 produced royalty income in recent years. Based on the Listing, the Trust derives its receipts principally from copyrights established in or prior to 1954 in the United States. The receipts fluctuate based on consumer interest in the nostalgia appeal of older songs and the overall popularity of the songs contained in the Catalogue. The Catalogue also generates royalty income in foreign countries in which copyright is claimed.

A number of factors create uncertainties with respect to the Catalogue’s ability to continue to generate royalty income on a continuing, long-term basis for the Trust. These factors include: (i) the effect that foreign and domestic copyright laws and any changes thereto have or will have on renewal rights (e.g., vesting of renewal term rights), (ii) the length of the term of copyright protection under foreign and domestic copyright laws, (iii) reversionary rights that may affect whether EMI is able to retain its rights to the Copyrighted Songs during certain renewal terms (e.g., statutory termination of transfers or “copyright recapture”) and (iv) ongoing disputes regarding the payment and calculation of the Contingent Portion.

The Trust does not own the Catalogue or any copyrights or other intellectual property rights and is not responsible for collecting royalties in connection with the Catalogue. As the current owner and administrator of the Catalogue, EMI is obligated under the Asset Purchase Agreement to use its best efforts to collect all royalties, domestic and foreign, in connection with the Catalogue and to remit a portion of its royalty income to the Trust in accordance with its Contingent Portion payment obligation.

The Trust’s income is dependent, in part, on EMI’s ability to maintain its rights in the Copyrighted Songs through copyright protection. Although Copyrighted Songs may continue to generate royalty revenue after their copyrights have expired, in general as the copyrights for the Copyrighted Songs expire, less royalty income will be generated, and the size of each payment of the Contingent Portion will be reduced accordingly.

Based on the Listing, most of the Top 50 Songs obtained copyright registration under the U.S. Copyright Act of 1909 (the “1909 Act”) between 1926 and 1954. For copyrighted works subject to the 1909 Act, copyright law generally provides for a possible 95 years of copyright protection, subject to certain factors, including the initial registration date of each copyright and compliance with certain statutory provisions including notice and renewal. Based on the Listing, the Copyright expiration years for the Top 50 Songs, to the extent known, range between 2021 and 2049, as set forth in the Listing.

The Copyrighted Songs are subject to statutory rights of termination of transfers, which may impact whether EMI is able to retain its ownership of the Copyrighted Songs during their respective terms of copyright protection. For copyrights governed by the 1909 Act, this termination right vests at the end of two different renewal terms, which vary for each Copyrighted Song. As the owner of the Catalogue, EMI (and not the Trust) is responsible for administrating the Catalogue and seeking renewals of the Copyrighted Songs. The Asset Purchase Agreement provides that EMI is obligated to use its best efforts to secure renewals.

Contingent Portion Payments

Payments of the Contingent Portion to the Trust are ordinarily made on a quarterly basis, approximately two to three months after a quarter ends. The Trust distributes the amounts it receives in Contingent Portion payments to the Unit Holders after payment of, or withholdings in connection with, expenses and liabilities of the Trust.

The amount of each payment of the Contingent Portion is based on a formula provided in the Asset Purchase Agreement. Prior to the first quarter of 2010, the Contingent Portion was calculated as an amount ranging from 65% to 75% of gross royalty income from the exploitation of the Catalogue for each quarterly period, less royalty expenses. In addition, the Contingent Portion was guaranteed to be at least a minimum of $167,500 per quarter (the “Minimum Payment Obligation”).

Beginning with the first quarter of 2010, the Asset Purchase Agreement provides for certain changes with respect to the calculation of the Contingent Portion. One such change is that the Minimum Payment Obligation is no longer in effect. The Trust is also of the view that the Contingent Portion payable to the Trust changed to a fixed 75% of gross royalty income from the exploitation of the Catalogue for each quarterly period, less royalty related expenses (the “New Calculation Method”). However, EMI has disputed that the New Calculation Method is the correct interpretation of the Asset Purchase Agreement (the “Calculation Method Dispute”). As a result of the New Calculation Method not being applied, after giving effect to the Settlement described below, EMI’s payments of the Contingent Portion have been deficient, in the Trust’s view by the following amounts (as of December 31, 2025 (the “Calculation Method Underpayments”):

Quarterly Payment Period	Amount ofDeficiency ()
March 31, 2025
June 30, 2025
September 30, 2025
December 31, 2025
Total

All values are in US Dollars.

As of the date hereof, the Trust has not received any amounts in respect of the Calculation Method Underpayments, and EMI has expressly disagreed with the Trust. The Trust can offer no assurance that it will be able to recover any portion of the Calculation Method Underpayments or that it will resolve favorably the ongoing dispute relating to the New Calculation Method with respect to future payments of the Contingent Portion.

Recent Audit Settlement

On October 1, 2020, the Trust engaged Citrin Cooperman & Company LLP, an accounting firm specializing in auditing royalty income (“Citrin”), to conduct a special audit of the books and records of EMI administered by Sony/ATV to determine the areas and extent of underpayment, if any, of quarterly Contingent Portion payments payable to the Trust for the periods beginning January 1, 2016 and ended December 31, 2020 (the “Audit Period”). Citrin’s final report (the “Citrin Report”) was delivered to the Trustees on April 4, 2022. The Citrin Report identified multiple asserted royalty omissions and expense over-deductions from the Contingent Portion during the Audit Period in addition to the Calculation Method Underpayments. The Trust distributed the Citrin Report to EMI on or about April 13, 2022. EMI has disputed the findings of the Citrin Report.

On October 30, 2025 (the “Settlement Date”), the Trust, Trustees, EMI and certain EMI affiliates entered into a settlement agreement, effective as of July 1, 2025 (the “Settlement Agreement”), pursuant to which the parties agreed to settle (the “Settlement”) all claims (the “Settled Claims”) of the Trust and/or the Trustees (i) for all periods of time prior to December 31, 2024 relating to EMI’s obligation to make Contingent Portion payments under the Asset Purchase Agreement, and (ii) regarding the interpretation of certain provisions of the Asset Purchase Agreement that had been subject to a tolling agreement between EMI and the Trust.

Under the terms of the Settlement, among other things, (i) EMI made a payment to the Trust in the amount of $500,000 on November 5, 2025 in full and final settlement of the Settled Claims (the “Settlement Payment”), (ii) the Trust and EMI agreed to amend Section 1(c)(i)(A) of the Asset Purchase Agreement to provide that beginning with the quarterly period beginning July 1, 2025, in calculating any Contingent Portion Payment due and payable by EMI to the Trust, EMI shall cap the foreign sub-publishing fee between EMI and any foreign affiliate thereof at twenty-five percent (25%), which cap acts as a limitation on certain deductions that EMI can make against payments due to the Trust, and (iii) the Trust and EMI agreed to amend Section 1(c)(i)(B) of the Asset Purchase Agreement to provide that beginning with the quarterly period beginning July 1, 2025, EMI shall only be entitled to offset the costs associated with EMI obtaining U.S. copyright renewals for a song against royalty income collected by EMI in the U.S. for such song (and not against any foreign royalty income collected outside of the U.S. for such song), and this modification also serves to narrow permissible offsets to payments due from EMI to the Trust.

The Settlement includes all claims relating to the Calculation Method Dispute through December 31, 2024 and all claims relating to the underpayments included in the Citrin Report. The Settlement does not include any claims for any periods after December 31, 2024 nor does it resolve the Calculation Method Dispute. As such, the Trustees and EMI have not agreed to settle any claims relating to the Calculation Method Dispute or the Calculation Method Underpayments for any period of time after December 31, 2024. The Trust can offer no assurance that it will be able to recover any portion of the Calculation Method Underpayments that were not subject to the Settlement, or that it will favorably resolve the Calculation Method Dispute with respect to future payments of the Contingent Portion.

For the full text of the pro forma Asset Purchase Agreement, as amended by the Settlement Agreement, please refer to the Current Report on Form 8-K, dated October 30, 2025, which the Trust filed with the Securities and Exchange Commission on November 5, 2025.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

The Trustees and Unit Holders of Mills Music Trust

Opinion on the Financial Statements

We have audited the accompanying statements of cash receipts and disbursements of Mills Music Trust (the “Trust”) for each of the years in the two-year period ended December 31, 2025, and the related notes (collectively referred to as the “financial statements”). In our opinion, the financial statements present fairly, in all material respects, the cash receipts and disbursements of the Trust for each of the years in the two-year period ended December 31, 2025, in conformity with the basis of cash receipts and disbursements, which is a comprehensive basis of accounting other than accounting principles generally accepted in the United States of America, as described in Note 1 to the financial statements.

Basis for Opinion

These financial statements are the responsibility of the Trust’s management. Our responsibility is to express an opinion on the Trust’s financial statements based on our audits. We are a public accounting firm registered with the Public Company Accounting Oversight Board (United States)(“ PCAOB ”) and are required to be independent with respect to the Trust in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement, whether due to error or fraud. The Trust is not required to have, nor were we engaged to perform, an audit of its internal control over financial reporting. As part of our audits, we are required to obtain an understanding of internal control over financial reporting but not for the purpose of expressing an opinion on the effectiveness of the Trust’s internal control over financial reporting. Accordingly, we express no such opinion.

Our audits included performing procedures to assess the risks of material misstatement of the financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the financial statements. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the financial statements. We believe that our audits provide a reasonable basis for our opinion.

Critical Audit Matters

Critical audit matters are matters arising from the current period audit of the financial statement that were communicated or required to be communicated to the audit committee and that (1) relate to accounts or disclosures that are material to the financial statement and (2) involved our especially challenging, subjective, or complex judgements. We determined that there were no critical audit matters.

Other Matter

Attention is directed to Note 1 to the financial statements for information concerning a dispute with respect to certain amounts believed to be owed to Mills Music Trust.

We have served as the Trust’s auditor since 2020.

MILLS MUSIC TRUST

NOTES TO STATEMENTS OF CASH RECEIPTS AND DISBURSEMENTS

YEARS ENDED DECEMBER 31, 2025 AND 2024

NOTE 1. ACCOUNTING POLICIES AND GENERAL INFORMATION

Organization and Background

Mills Music Trust (the “ Trust ”) was created by a Declaration of Trust, dated December 3, 1964 (the “ Declaration of Trust ”), for the purpose of acquiring from Mills Music, Inc. (“ Old Mills ”) the right to receive payment of a deferred contingent purchase price obligation (the “ Contingent Portion ”) payable to Old Mills. The obligation to pay the Contingent Portion arose as the result of the sale by Old Mills of its music and lyric copyright catalogue (the “ Catalogue ”) to a newly formed company pursuant to an asset purchase agreement dated December 5, 1964 (the “ Asset Purchase Agreement ”). Pursuant to the Asset Purchase Agreement, payment of the Contingent Portion to the Trust continues until the end of the year in which the last copyright in the Catalogue expires and cannot be renewed.

The Contingent Portion amounts are currently payable by EMI Mills Music Inc. (“ EMI ”), the owner of the copyrighted materials contained in the Catalogue. The Trust has been advised that Sony/ATV Music Publishing LLC (“ Sony/ATV ”) is the administrator and manager of EMI and the Catalogue.

HSBC Bank, USA, N.A. is the Corporate Trustee of the Trust (the “ Corporate Trustee ”) and Lee Eastman is the Individual Trustee of the Trust (the “ Individual Trustee ” and together with the Corporate Trustee, the “ Trustees ”).

Proceeds from Contingent Portion Payments

The Trust receives quarterly payments of the Contingent Portion from EMI and distributes the amounts it receives to the registered owners of Trust Certificates (the “ Unit Holders ”) representing interests in the Trust (the “ Trust Units ”), after payment of, or withholdings in connection with, expenses and liabilities of the Trust. The Declaration of Trust provides that these are the Trust’s sole responsibilities and that the Trust is prohibited from engaging in any business activities.

Cash Distributions to Unit Holders

The Declaration of Trust provides for the distribution to the Unit Holders of all funds the Trust receives after payment of, or withholdings in connection with, expenses and liabilities of the Trust.

Contingent Portion Payments

Beginning with the first quarter of 2010, the Asset Purchase Agreement provides for certain changes with respect to the calculation of the Contingent Portion. One such change is that the Minimum Payment Obligation is no longer in effect. The Trust is also of the view that the Contingent Portion payable to the Trust changed to a fixed 75% of gross royalty income from the exploitation of the Catalogue for each quarterly period, less royalty related expenses (the “ New Calculation Method ”). However, EMI has disputed that the New Calculation Method is the correct interpretation of the Asset Purchase Agreement (the “Calculation Method Dispute”). As a result of the New Calculation Method not being applied, after giving effect to the Settlement described below, EMI’s payments of the Contingent Portion have been deficient, in the Trust’s view by the following amounts as of December 31, 2025 (the “ Calculation Method Underpayments ”):

Recent Audit Settlement

On October 1, 2020, the Trust engaged Citrin Cooperman & Company LLP, an accounting firm specializing in auditing royalty income (“ Citrin ”), to conduct a special audit of the books and records of EMI administered by Sony/ATV to determine the areas and extent of underpayment, if any, of quarterly Contingent Portion payments payable to the Trust for the periods beginning January 1, 2016 and ended December 31, 2020 (the “ Audit Period ”). Citrin’s final report (the “ Citrin Report ”) was delivered to the Trustees on April 4, 2022. The Citrin Report identified multiple asserted royalty omissions and expense over-deductions from the Contingent Portion during the Audit Period in addition to the Calculation Method Underpayments. The Trust distributed the Citrin Report to EMI on or about April 13, 2022. EMI has disputed the findings of the Citrin Report.

The Settlement includes all claims relating to the Calculation Method Dispute through December 31, 2024 and all claims relating to the underpayments in the Citrin Report. The Settlement does not include any claims for any periods after December 31, 2024 nor does it resolve the Calculation Method Dispute. As such, the Trustees and EMI have not agreed to settle any claims relating to the Calculation Method Dispute or the Calculation Method Underpayments for any period of time after December 31, 2024. The Trust can offer no assurance that it will be able to recover any portion of the Calculation Method Underpayments that were not subject to the Settlement, or that it will favorably resolve the Calculation Method Dispute with respect to future payments of the Contingent Portion.

Recent Distributions

Cash and Administrative Expenses

As of December 31, 2025 the Trust had an aggregate of $0

in unpaid administrative expenses for services rendered to the Trust. As of March 31, 2026, the Trust had no unpaid administrative expenses for services rendered to the Trust prior to such date.

Recent Accounting Pronouncements

The Trustees do not believe that any recently issued, but not yet effective, accounting standards, if adopted, would have a material effect on the Trust’s financial statement.

Accounting Policies

Payments from EMI to the Trust of the Contingent Portion are typically made in March, June, September and December for the prior calendar quarter. The payments received are accounted for on a cash basis, as are expenses. The Declaration of Trust provides for the distribution of all funds received by the Trust to the Unit Holders after expenses are paid.

NOTE 2. FEDERAL INCOME TAXES

No provision for income taxes has been made since the liability thereof is that of the Unit Holders and not the Trust.

NOTE 3. RELATED PARTY TRANSACTIONS

The Trustees are paid in accordance with the Declaration of Trust, which provides that each Trustee shall receive annual compensation of $2,500, provided that such aggregate compensation to the Trustees as a group may not exceed 3% of the Contingent Portion amounts received by the Trust in any year. The Declaration of Trust also provides for the reimbursement of expenses reasonably incurred in the performance of a Trustee’s duties to the Trust, including clerical and administrative services. Accordingly, the Trustees are entitled to receive annual compensation and reimbursement for services performed for the Trust, including the Corporate Trustee’s services as the Registrar and Transfer Agent of the certificates representing the Trust Units. No expense is being charged or paid by the Trust for the office space and office equipment of the Corporate Trustee that is being utilized for the Trust. The Declaration of Trust also provides that if a Trustee performs unusual or extraordinary services, reasonable compensation for such services shall be paid, subject to the terms and conditions of the Declaration of Trust.

Pursuant to the Declaration of Trust, disbursements were made as follows to the Trustees for the years ended December 31, 2025 and December 31, 2024:

Trustee Fees Paid by the Trust
Individual Trustee Fees	2,500	$ 3,125
Corporate Trustee Fees	2,500	2,500
Corporate Trustee Transfer Agent Registrar Fees<br>(1)	27,500	24,375
Totals	32,500	$ 30,000

All values are in US Dollars.

(1)	These services are performed by the Corporate Trustee.

NOTE 4. THE COPYRIGHT CATALOGUE

The Catalogue is estimated to be composed of over 12,000 music titles (the “ Copyrighted Songs ”), of which approximately 1,430 produced royalty income in recent years. Based on the Listing, the Trust derives its receipts principally from copyrights established in or prior to 1954 in the United States. The receipts fluctuate based on consumer interest in the nostalgia appeal of older songs and the overall popularity of the songs contained in the Catalogue. The Catalogue also generates royalty income in foreign countries in which copyright is claimed.

Based on the Listing, most of the Top 50 Songs obtained copyright registration under the U.S. Copyright Act of 1909 (the “ 1909 Act” ) between 1926 and 1954. For copyrighted works subject to the 1909 Act, copyright law generally provides for a possible 95 years of copyright protection, subject to certain factors, including the initial registration date of each copyright and compliance with certain statutory provisions including notice and renewal. Based on the Listing, the Copyright expiration years for the Top 50 Songs, to the extent known, range between 2021 and 2049, as set forth in the Listing.

NOTE 5. SEGMENT INFORMATION

The Trust reports segment information based on the management approach which designates the internal reporting used by the Chief Operating Decision Maker, which are the Trust’s Trustees (in such capacities, collectively, the “ CODM ”), for making decisions and assessing performance as the source of the Trust’s reportable segments.

The Trust has one reportable segment: receiving quarterly payments of the Contingent Portion from EMI and distributing the amounts it receives to the Unit Holders, after payment of, or withholdings in connection with, expenses and liabilities of the Trust. As the Trust operates in one reportable segment, the CODM evaluates the performance of the Trust based on the aggregate amount of cash distributions which the Trust is able to pay to Unit Holders. The key performance metric considered by the CODM is cash distributions per Trust Unit. Material cash receipts, disbursements and withholdings of the Trust which are reviewed by the CODM include receipts of the Contingent Portion from EMI and administrative expenses, which primarily consist of third party service provider fees (including legal, accounting, auditor and printer fees) and Trustee and Transfer Agent Registrar fees. The CODM will continue to evaluate its segment reporting disclosures and make adjustments if and to the extent there are material changes in financial reporting requirements.

NOTE 6. OTHER MATTERS

None.

ITEM 9. CHANGES IN AND DISAGREEMENTS WITH ACCOUNTANTS ON ACCOUNTING AND FINANCIAL DISCLOSURE

None.

ITEM 9A. CONTROLS AND PROCEDURES

Evaluation of Disclosure Controls and Procedures

The Trust maintains disclosure controls and procedures that are designed to ensure that information required to be disclosed in this report under the Securities Exchange Act of 1934 (the “ Exchange Act” ) is recorded, processed, summarized and reported within the time periods specified in the SEC’s rules and forms, and that such information is accumulated and communicated to the Trust’s management, which is comprised of the Trust Officer of the Corporate Trustee and the Chief Financial Individual providing accounting services to the Trust, to allow timely decisions regarding required disclosures. Any controls and procedures, no matter how well designed and operated, can provide only reasonable assurance of achieving the desired control objectives. The Trust’s management has evaluated the effectiveness of the design and operation of the Trust’s disclosure controls and procedures as of December 31, 2025. Based upon that evaluation and subject to the foregoing, the Trust’s management concluded that the design and operation of the Trust’s disclosure controls and procedures provided reasonable assurance that the disclosure controls and procedures are effective to accomplish their objectives.

Management’s Annual Report on Internal Control over Financial Reporting

Management of the Trust is responsible for establishing and maintaining adequate internal control over financial reporting for the Trust as defined in Rule 13a-15(f) under the Exchange Act. The Trust’s internal control over financial reporting is designed to provide reasonable assurance to management regarding the preparation and fair presentation of published financial statements and the reliability of financial reporting.

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Therefore, even those systems determined to be effective can provide only reasonable assurance with respect to financial statement preparation and presentation.

Management assessed the effectiveness of the Trust’s internal control over financial reporting as of December 31, 2025. In making this assessment, management used the criteria set forth by the Committee of Sponsoring Organizations of the Treadway Commission in Internal Control – Integrated Framework . Based on management’s assessment, the Trust believes that, as of December 31, 2025, the Trust’s internal control over financial reporting is effective based on those criteria.

This annual report does not include an attestation report of the Trust’s independent registered public accounting firm regarding internal control over financial reporting. Management’s report was not subject to attestation by the Trust’s independent registered public accounting firm pursuant to rules of the Securities and Exchange Commission that permit the Trust to provide only management’s report in this annual report on Form 10-K.

Changes in Internal Control Over Financial Reporting

There were no changes in the Trust’s internal control over financial reporting (as defined in Rule 13a-15(f) under the Exchange Act) during the quarter ended December 31, 2025 that materially affected, or are reasonably likely to materially affect, the Trust’s internal control over financial reporting.

ITEM 9B. OTHER INFORMATION

10b5-1 Trading Plans

During the three months ended December 31, 2025, none of the Trustees adopted or terminated any contract, instruction or written plan for the purchase or sale of our securities that was intended to satisfy the affirmative defense conditions of Rule 10b5-1(c) under the Exchange Act or any “non-Rule 10b5-1 trading arrangement” as defined in Item 408(c) of Regulation S-K.

PART III

ITEM 10. DIRECTORS, EXECUTIVE OFFICERS AND CORPORATE GOVERNANCE

The Trust does not have, nor does the Declaration of Trust provide for, officers, a board of directors or any employees. HSBC Bank, USA, N.A. is the Corporate Trustee of the Trust and Lee Eastman is the Individual Trustee of the Trust. Pursuant to the Declaration of Trust, Trustees of the Trust serve until their removal or resignation, or in the case of Individual Trustees, their incapacity or death. Michael Reiss resigned as an Individual Trustee of the Trust effective as of March 15, 2024. and his Individual Trustee seat is vacant as of March 31, 2026. For more information regarding his resignation please refer to the Current Report on Form 8-K, which the Trust filed with the Securities and Exchange Commission on March 21, 2024.

HSBC Bank, USA, N.A.—The Corporate Trustee (or its predecessor, Marine Midland Bank) has been the Corporate Trustee of the Trust since February 1965 and is a national banking association organized under the laws of the United States.

Lee Eastman—Mr. Eastman is the principal lawyer at the firm of Eastman & Eastman. He is also responsible for the day to day operations of MPL Communications, Inc. and MPL Music Publishing, Inc. and is a principal of various music publishing interests.

He has served on the Stanford Law School Board of Visitors and has been a guest speaker on the entertainment business at Stanford Law School.

Code of Ethics

On December 23, 2014, the Trust adopted a code of ethics (as defined in Item 406 of Regulation S-K under the Securities Act of 1933) applicable to the Individual Trustees and the Trust Officers of the Corporate Trustee to the extent they provide services to the Trust (the “Code of Ethics”). A copy of the Code of Ethics will be provided to any person without charge upon written request to the Trust at its administrative office, c/o HSBC BANK USA, N.A., Corporate Trust, Issuer Services, 66 Hudson Boulevard East, New York, NY 10001. In addition, the Trust relies on the Corporate Trustee to abide by HSBC Bank, USA, N.A.’s Statement of Business Principles and Code of Ethics, which is available on the Corporate Trustee’s website at https://www.hsbc.com/who-we-are/esg-and-responsible-business/our-conduct.

Audit Committee

The Trust is not a corporate entity and thus does not have an Audit Committee. The Trust has established a policy with regard to audit, audit-related and certain non-audit engagements of its independent auditors. Under this policy, the Trust annually approves certain limited, specified recurring services which may be provided by the Trust’s accountant or independent auditors. All other engagements for services to be performed by the Trust’s independent auditors must be separately pre-approved by the Trust. Joel Faden acts as Chief Financial Individual providing accounting services for the Trust.

Insider Trading Policy

The Trust has not adopted insider trading policies and procedures governing the purchase, sale, and other dispositions of the Trust’s securities by its directors, officers, and employees. The Trust does not have, nor does the Declaration of Trust require or provide for, officers, a board of directors or any employees. As of December 23, 2014, the Trust adopted a code of ethics (as defined in Item 406 of Regulation S-K under the Securities Act of 1933) (the “Code of Ethics”) applicable to the Individual Trustees and the Trust Officers of the Corporate Trustee to the extent they provide services to the Trust on behalf of the Corporate Trustee (each, a “Covered Individual”). Among other things, the Code of Ethics requires each Covered Individual to comply with the Declaration of Trust and all applicable governmental laws, rules and regulations, and to take reasonable steps and measures to avoid actual or apparent conflicts of interest. The Code of Ethics states that a conflict of interest arises when, among other things, a Covered Individual uses its position to advance a personal gain or advantage on the basis of sensitive information gained when acting in such capacity. In addition, as the Declaration of Trust requires the Trust to distribute to Unit Holders all funds it receives after payment of, or withholdings in connection with, expenses and liabilities of the Trust, the Trust is prohibited from expending any amounts to purchase Trust Units. Due to the Trust’s structure, the existence of the Code of Ethics and the restrictions set forth in the Declaration of Trust, the Trustees have not adopted insider trading policies and procedures for the Trust. The Trustees will continue to evaluate whether adopting such policies and procedures would be appropriate in the future.

ITEM 11. EXECUTIVE COMPENSATION

The Trust does not have, nor does the Declaration of Trust provide for, officers, a board of directors or any executives.

The Trustees are paid in accordance with the Declaration of Trust, which provides that each Trustee shall receive annual compensation of $2,500, provided that such aggregate compensation to the Trustees as a group may not exceed 3% of the Contingent Portion amounts received by the Trust in any year. The Declaration of Trust also provides for the reimbursement of expenses reasonably incurred in the performance of a Trustee’s duties to the Trust, including clerical and administrative services. Accordingly, the Trustees are entitled to receive annual compensation and reimbursement for services performed for the Trust, including the Corporate Trustee’s services as the Registrar and Transfer Agent of the certificates representing the Trust Units. The Declaration of Trust also provides that if a Trustee performs unusual or extraordinary services, reasonable compensation for such services shall be paid, subject to the terms and conditions of the Declaration of Trust. See Note 3, “Related Party Transactions” under Part II, Item 8, “Financial Statements and Supplementary Data” for information regarding payments by the Trust to the Trustees made in accordance with the Declaration of Trust.

The Declaration of Trust does not provide for any bonuses, stock awards, option awards, non-equity incentive plan compensation or nonqualified deferred compensation earnings. The Trust does not have severance agreements nor does it provide post-retirement benefits to any of the Trustees.
