Audit Committee Pre-Approval Policies and Procedures:

The registrant's Audit Committee ("audit committee") has adopted an "Audit Committee Charter (Amended and Restated as of September 14, 2016)" (the "charter"). The charter contains the audit committee's pre-approval policies and procedures. Reproduced below is an excerpt from the charter regarding pre-approval policies and procedures:

The [audit] Committee shall:

…

2.

Pre-approve (a) all audit and permissible non-audit services1 to be provided to the Fund and (b) all permissible non-audit services to be provided by the Fund's independent auditors to UBS AM and any Covered Service Providers, if the engagement relates directly to the operations and financial reporting of the Fund. In carrying out this responsibility, the Committee shall seek periodically from UBS AM and from the independent auditors a list of such audit and permissible non-audit services that can be expected to be rendered to the Fund, UBS AM or any Covered Service Providers by the Fund's independent auditors, and an estimate of the fees sought to be paid in connection with such services. The Committee has delegated its responsibility to pre-approve any such audit and permissible non-audit services not exceeding $100,000 (excluding reasonable out-of-pocket expenses) on an annual basis to the Chairperson. All such pre-approvals will be reported to the full Committee on a quarterly basis at the Committee's next regularly scheduled meeting after the pre-approval. The Committee may not delegate to management its responsibility to pre-approve services to be performed by the independent auditor. Requests or applications to provide services that require specific pre-approval by the Committee or the Chairperson will be submitted by both the Fund's independent auditors and the Fund's Treasurer or other designated Fund officer and must include a joint statement as to whether, in their view, the request or application is consistent with SEC rules on auditor independence. From year to year, the Committee shall report to the Board whether this system of pre-approval has been effective and efficient or whether this Charter should be amended to allow for pre-approval pursuant to such policies and procedures as the Committee shall approve, including the delegation of some or all of the Committee's pre-approval responsibilities to other persons (other than UBS AM or the Fund's officers).

¹ The Committee will not approve non-audit services that the Committee believes may taint the independence of the auditors. Currently, permissible non-audit services include any professional services (including tax services) that are not prohibited services as described below, provided to the Fund by the independent auditors, other than those provided to the Fund in connection with an audit or a review of the financial statements of the Fund. Permissible non-audit services may notinclude: (i) bookkeeping or other services related to the accounting records or financial statements of the Fund; (ii) financial information systems design and implementation; (iii) appraisal or valuation services, fairness opinions or contribution-in-kind reports; (iv) actuarial services; (v) internal audit outsourcing services; (vi) management functions or human resources; (vii) broker or dealer, investment adviser or investment banking services; (viii) legal services and expert services unrelated to the audit; and (ix) any other service the Public Company Accounting Oversight Board determines, by regulation, is impermissible.

Pre-approval by the Committee of any permissible non-audit services is not required so long as: (i) the aggregate amount of all such permissible non-audit services provided to the Fund, UBS AM and any service providers controlling, controlled by or under common control with UBS AM that provide ongoing services to the Fund ("Covered Service Providers") constitutes not more than 5% of the total amount of revenues paid to the independent auditors (during the fiscal year in which the permissible non-audit services are provided) by (a) the Fund, (b) its investment adviser and (c) any entity controlling, controlled by, or under common control with the investment adviser that provides ongoing services to the Fund during the fiscal year in which the services are provided that would have to be approved by the Committee; (ii) the permissible non-audit services were not recognized by the Fund at the time of the engagement to be non-audit services; and (iii) such services are promptly brought to the attention of the Committee and approved by the Committee (or its delegate(s)) prior to the completion of the audit.

(e) (2)

(g)

For the fiscal years ended December 31, 2025 and December 31, 2024, the aggregate fees billed by EY of $2,963,436 and $1,548,108, respectively, for non-audit services rendered on behalf of the registrant ("covered"), its investment adviser (not including any sub-adviser whose role is primarily portfolio management and is subcontracted with or overseen by another investment adviser) and any entity controlling, controlled by, or under common control with the adviser ("non-covered") that provides ongoing services to the registrant for each of the last two fiscal years of the registrant is shown in the table below:

			2025				2024
	Covered Services		$	11,492			$	11,462
	Non-Covered Services		$	2,951,944			$	1,536,646

(h)

The registrant's audit committee was not required to consider whether the provision of non-audit services that were rendered to the registrant's investment adviser (not including any sub-adviser whose role is primarily portfolio management and is subcontracted with or overseen by another investment adviser), and any entity controlling, controlled by, or under common control with the investment adviser that provides ongoing services to the registrant that were not pre-approved pursuant to paragraph (c)(7)(ii) of Rule 2-01 of Regulation S-X is compatible with maintaining the principal accountant's independence.

SMA Relationship Trust-Series M

Notes to financial statements

Organization and significant accounting policies

SMA Relationship Trust (the "Trust") is an open-end management investment company registered with the US Securities and Exchange Commission ("SEC") under the Investment Company Act of 1940, as amended, (the "1940 Act"), currently offering one series.

The Trust has one series available for investment, Series M (the "Fund"). The Fund is classified as a non-diversified investment company for purposes of the 1940 Act. The investment objective of the Fund is to seek total return consisting of capital appreciation and current income exempt from federal income tax. The Fund pursues its investment objective by investing primarily in municipal bonds.

UBS Asset Management (Americas) LLC ("UBS AM") is the investment advisor and administrator for the Fund. UBS Asset Management (US) Inc. ("UBS AM (US)") serves as the principal underwriter for the Fund. UBS AM and UBS AM (US) are indirect wholly owned subsidiaries of UBS Group AG. UBS Group AG is an internationally diversified organization with headquarters in Zurich, Switzerland. UBS Group AG operates in many areas of the financial services industry.

In the normal course of business, the Fund may enter into contracts that contain a variety of representations that provide indemnification for certain liabilities. The Fund's maximum exposure under these arrangements is unknown, as this would involve future claims that may be made against the Fund that have not yet occurred. However, there have been no prior claims or losses pursuant to these contracts and the Fund expects the risk of loss to be remote.

The Financial Accounting Standards Board ("FASB") Accounting Standards Codification ("ASC") is the exclusive reference of authoritative US generally accepted accounting principles ("US GAAP") recognized by the FASB to be applied by nongovernmental entities. Rules and interpretive releases of the SEC under authority of federal laws are also sources of authoritative US GAAP for SEC registrants. The Fund's financial statements are prepared in accordance with US GAAP, which may require the use of management estimates and assumptions. Actual results could differ from those estimates.

The Fund adopted FASB Accounting Standards Update 2023-07, Segment Reporting (Topic 280)-Improvements to Reportable Segment Disclosures ("ASU 2023-07"). Adoption of the new standard impacts financial statement disclosures only and does not affect the Fund's financial position or the results of its operations. An operating segment is defined in Topic 280 as a component of a public entity that engages in business activities from which it may recognize revenues and incur expenses, has operating results that are regularly reviewed by the public entity's chief operating decision maker (CODM) to make decisions about resources to be allocated to the segment and assess its performance, and has discrete financial information available. The Fund's portfolio management team acts as the Fund's CODM. The Fund represents a single operating segment, as the CODM monitors the operating results of the Fund as a whole, and the Fund's long-term strategic asset allocation is pre-determined in accordance with the Fund's single investment objective which is executed by the Fund's portfolio managers as a team. The financial information in the form of the Fund's portfolio composition, total returns, expense ratios and changes in net assets (i.e., changes in net assets resulting from operations, subscriptions and redemptions) which are used by the CODM to assess the segment's performance versus the Fund's comparative benchmarks and to make resource allocation decisions for the Fund's single segment, is consistent with that presented within the Fund's financial statements. Segment assets are reflected on the accompanying statement of assets and liabilities as "total assets" and significant segment expenses are listed on the accompanying statement of operations.

The following is a summary of significant accounting policies:

Investment transactions, investment income and expenses: Investment transactions are recorded on the trade date. Realized gains and losses from investment transactions are calculated using the specific identified cost method. Dividend income and expenses are recorded on the ex-dividend date ("ex-date"). Interest income is

SMA Relationship Trust-Series M

Notes to financial statements

recorded on an accrual basis. Discounts are accreted and premiums are amortized as adjustments to interest income and the identified cost of investments.

Dividends and distributions: Dividends and distributions to shareholders are recorded on the ex-dividend date. The amount of dividends from net investment income and distributions from net realized capital gains and/or return of capital are determined in accordance with US federal income tax regulations, which may differ from US GAAP. These "book/tax" differences are either considered temporary or permanent in nature. To the extent these differences are permanent in nature, such amounts are reclassified within the capital accounts based on their federal tax-basis treatment; temporary differences do not require reclassification.

Concentration of risk: The ability of the issuers of debt securities held by the Fund to meet their obligations may be affected by economic, political and other developments particular to a specific industry, country, state or region.

Valuation of investments

The Fund generally calculates its net asset value on days that the New York Stock Exchange ("NYSE") is open. The Fund calculates net asset value as of the close of regular trading on the NYSE (generally, 4:00 p.m., Eastern Time). The NYSE normally is not open, and the Fund does not price its shares, on most national holidays and Good Friday. To the extent that the Fund's assets are traded in other markets on days when the NYSE is not open, the value of the Fund's assets may be affected on those days. If trading on the NYSE is halted for the day before 4:00 p.m., Eastern Time, the Fund's net asset value per share generally will still be calculated as of the close of regular trading on the NYSE. The time at which the Fund calculates its net asset value and until which purchase, sale or exchange orders are accepted may be changed as permitted by the SEC.

The Fund calculates its net asset value based on the current market value, where available, for its portfolio investments. The Fund normally obtains market values for its investments from independent pricing sources and broker dealers. Independent pricing sources may use reported last sale prices, official market closing prices, current market quotations or valuations from computerized "evaluation" systems that derive values based on comparable investments. An evaluation system incorporates parameters such as security quality, maturity and coupon, and/or research and evaluations by its staff, including review of broker-dealer market price quotations, if available, in determining the valuation of the portfolio investments. Investments also may be valued based on appraisals derived from information concerning the investment or similar investments received from recognized dealers in those holdings.

Investments traded in the over-the-counter ("OTC") market and listed on The NASDAQ Stock Market, Inc. ("NASDAQ") normally are valued at the NASDAQ Official Closing Price. Other OTC securities are valued at the last bid price on the valuation date available prior to valuation. Investments which are listed on US and foreign stock exchanges normally are valued at the market closing price, the last sale price on the day the securities are valued or, lacking any sales on such day, at the last available bid price. Investments listed on foreign stock exchanges may be fair valued based on significant events that have occurred subsequent to the close of the foreign markets. In cases where investments are traded on more than one exchange, the investments are valued on the exchange designated as the primary market by UBS AM. If a market value is not readily available from an independent pricing source for a particular investment, that investment is valued at fair value as determined in good faith by UBS AM as the valuation designee appointed by the Fund's Board of Trustees (the "Board") pursuant to Rule 2a-5 under the 1940 Act. Foreign currency exchange rates are generally determined as of the close of the NYSE.

The amortized cost method of valuation, which approximates market value, generally is used to value short-term debt instruments with 60 days or less remaining to maturity, unless UBS AM determines that this does not represent fair value.

Investments in open-end investment companies are valued at the daily closing net asset value of the respective investment company. Pursuant to the Fund's use of the practical expedient within ASC Topic 820, Fair Value

SMA Relationship Trust-Series M

Notes to financial statements

Measurement, investments in investment companies without publicly published prices are also valued at the daily net asset value.

The Board has designated UBS AM as the valuation designee pursuant to Rule 2a-5 under the 1940 Act and delegated to UBS AM the responsibility for making fair value determinations with respect to portfolio holdings. UBS AM, as the valuation designee, is responsible for periodically assessing any material risks associated with the determination of the fair value of investments; establishing and applying fair value methodologies; testing the appropriateness of fair value methodologies; and overseeing and evaluating third party pricing services. UBS AM has engaged the Equities, Fixed Income and Multi-Asset Valuation Committee (the "VC") to assist with its designated responsibilities as valuation designee. Fair valuation determinations are subject to review at least monthly by the VC during scheduled meetings. Pricing decisions, processes, and controls over fair value determinations are subject to internal and external reviews, including annual internal compliance reviews and periodic internal audit reviews.

The types of investments for which such fair value pricing may be necessary include, but are not limited to: foreign investments under some circumstances; securities of an issuer that has entered into a restructuring; investments whose trading has been halted or suspended; fixed income securities that are in default and for which there is no current market value quotation; and investments that are restricted as to transfer or resale. The need to fair value a Fund's portfolio investments may also result from low trading volume in foreign markets or thinly traded domestic investments, and when a security that is subject to a trading limit or collar on the exchange or market on which it is primarily traded reaches the "limit up" or "limit down" price and no trading has taken place at that price. Various factors may be reviewed in order to make a good faith determination of an investment's fair value. These factors include, but are not limited to, fundamental analytical data relating to the investment; the nature and duration of restrictions on disposition of the investment; and the evaluation of forces which influence the market in which the investment is purchased and sold. Valuing investments at fair value with unobservable inputs involves greater reliance on judgment than valuing investments that have readily available market quotations. Fair value determinations can also involve reliance on quantitative models employed by a fair value pricing service.

US GAAP requires disclosure regarding the various inputs that are used in determining the value of the Fund's investments. These inputs are summarized into the three broad levels listed below:

Level 1-Unadjusted quoted prices in active markets for identical investments.

Level 2-Other significant observable inputs, including but not limited to, quoted prices for similar investments, interest rates, prepayment speeds and credit risks.

Level 3-Unobservable inputs inclusive of the Fund's own assumptions in determining the fair value of investments.

A fair value hierarchy table has been included near the end of the Fund's Portfolio of investments.

Investments

Municipal securities risk: Municipal securities are subject to interest rate, credit, illiquidity, market and political risks. The ability of a municipal issuer to make payments and the value of municipal securities can be affected by uncertainties in the municipal securities market. Such uncertainties could cause increased volatility in the municipal securities market and could negatively impact the Fund's net asset value and/or the distributions paid by the fund. Municipal bonds secured by revenues from public housing authorities may be subject to additional uncertainties relating to the possibility that proceeds may exceed supply of available mortgages to be purchased by public housing authorities, resulting in early retirement of bonds, or that homeowner repayments will create an irregular cash flow. Municipalities continue to experience difficulties in the current economic and political environment.

SMA Relationship Trust-Series M

Notes to financial statements

Restricted securities: The Fund may invest in securities that are subject to legal or contractual restrictions on resale. These securities generally may be resold in transactions exempt from registration or to the public if the securities are registered. Disposal of these securities may involve time-consuming negotiations and expenses, and prompt sale at an acceptable price may be difficult. Information regarding restricted securities, if any, is included in the Fund's Portfolio of investments.

Investment advisory and administration fees and other transactions with affiliates

The Fund's Board has approved an investment advisory and administration contract ("Advisory Contract") with UBS AM under which UBS AM serves as investment advisor and administrator of the Fund. Pursuant to the Advisory Contract, the Fund will not pay a fee to UBS AM for investment advisory services provided by UBS AM.

UBS AM (not the Fund) pays all ordinary operating expenses, interest expense, and commitment fees (i.e., bank line of credit facility fees), excluding extraordinary litigation expenses and any acquired fund fees and expenses, incurred by the Fund. The Fund is part of a wrap fee program or other program advised or sub-advised by UBS AM or its affiliates, clients of which often pay a single aggregate fee for all costs and expenses of the program.

The Fund may invest in shares of certain affiliated investment companies also advised or managed by the Advisor. Investments in affiliated investment companies for the period ended December 31, 2025, if any, have been included near the end of the Fund's Portfolio of investments.

Securities lending

The Fund may lend securities up to 33¹​/₃% of its total assets to qualified broker-dealers or institutional investors. The loans are initially secured by cash, U.S. government securities and irrevocable letters of credit in an amount at least equal to 102% of the market value of the securities loaned with respect to domestic securities and 105% of the market value of the securities loaned with respect to foreign securities. In the event that the market value of the cash, U.S. government securities, and irrevocable letters of credit securing the loan falls below 100% of the market value for domestic securities, and 103% for foreign securities, the borrower must provide additional cash, U.S. government securities, and irrevocable letters of credit so that the total securing of the loan is at least 102% of the market value for domestic securities and 105% of the market value for foreign securities.

The Fund will regain ownership of loaned securities to exercise certain beneficial rights; however, the Fund may bear the risk of delay in recovery of, or even loss of rights in, the securities loaned should the borrower fail financially. The Fund receives compensation for lending its securities from interest or dividends earned on the cash, U.S. government securities and irrevocable letters of credit held as collateral, net of fee rebates paid to the borrower plus reasonable administrative and custody fees. Cash collateral received is invested in State Street Navigator Securities Lending Government Money Market Fund, which is included in the Fund's Portfolio of investments. State Street Bank and Trust Company serves as the Fund's lending agent.

At December 31, 2025, the Fund did not have any securities on loan.

Bank line of credit

The Fund participates with other funds managed by UBS AM in a $185 million committed credit facility (the"Committed Credit Facility") with State Street Bank and Trust Company. The Committed Credit Facility is to be utilized for temporary financing until the settlement of sales or purchases of portfolio securities, the repurchase or redemption of shares of a participating fund at the request of shareholders and other temporary or emergency purposes. The expiration date of the line of credit agreement was March 31, 2025 and was renewed on April 1, 2025 with the same fees and terms expiring March 30, 2026.

SMA Relationship Trust-Series M

Notes to financial statements

Interest on amounts borrowed is calculated based on prevailing rates in effect at the time of borrowing. The Advisor has agreed to pay an annual 25 basis point commitment fee on the portion of the average daily balance of the Committed Credit Facility not utilized by the Fund. Commitment fees have been allocated among the funds participating in the Committed Credit Facility as follows: 50% of the allocation is based on the relative asset size of funds and the other 50% of the allocation is based on utilization.

For the period ended December 31, 2025, the Fund had borrowings as follows:

Average daily amount of borrowing outstanding				Days outstanding				Interest expense*				Weighted average annualized interest rate
$	5,327,677				5			$	4,070				5.500	%

* Interest expense is the responsibility of the Advisor.

Purchases and sales of securities

For the period ended December 31, 2025, aggregate purchases and sales of portfolio securities, excluding short-term securities, were $161,228,532 and $174,535,022, respectively. The calculation of the purchases and sales proceeds excludes transactions involving variable-rate demand notes, which are considered short-term instruments due to the ability to demand immediate repayment.

Shares of beneficial interest

There is an unlimited number of shares of no par value beneficial interest authorized. Transactions in shares of beneficial interest for the Fund were as follows:

				For the year ended December 31, 2025				For the year ended December 31, 2024
Shares sold					14,554,269				10,653,362
Shares repurchased					(16,623,566	)			(11,237,331	)
Dividends reinvested					2,310				568
Net increase (decrease) in shares outstanding					(2,066,987	)			(583,401	)

Federal tax status

It is the Fund's policy to comply with all requirements of the Internal Revenue Code applicable to regulated investment companies and to distribute substantially all of its taxable income to its shareholders. In addition, by distributing during each calendar year substantially all of its net investment income, net realized capital gains and certain other amounts, if any, the Fund intends not to be subject to a federal excise tax. Accordingly, no federal income tax provision was required.

The tax character of distributions paid during the fiscal year ended December 31, 2025 and December 31, 2024 was as follows:

Distributions paid from:				2025				2024
Tax-exempt income				$	9,412,589			$	11,213,381
Ordinary Income					62,283				216,492

SMA Relationship Trust-Series M

Notes to financial statements

Aggregate cost for federal income tax purposes, including derivatives (if any), was $324,648,104; and net unrealized appreciation (depreciation), including derivatives (if any) consisted of:

Gross unrealized appreciation				$	1,611,037
Gross unrealized depreciation					(3,896,409	)
Net unrealized appreciation (depreciation)					(2,285,372	)

At December 31, 2025, the components of accumulated earnings (deficit) on a tax basis were as follows:

Accumulated realized capital and other losses				$	(15,169,752	)
Net unrealized appreciation/(depreciation) of investments					(2,285,372	)
Total accumulated earnings (deficit)					(17,455,124	)

Net capital losses recognized by the Fund may be carried forward indefinitely, and retain their character as short-term and/or long-term losses. These carryforwards are available as a reduction, to the extent provided in the regulations, of future realized capital gains. To the extent that such losses are used to offset future net realized capital gains, it is probable these gains will not be distributed. Losses incurred that will be carried forward indefinitely are as follows:

Short-term losses				$	1,156,545
Long-term losses					14,013,207
Net capital losses					15,169,752

During the fiscal year ended, the Fund did not utilize any capital loss carryforwards to offset current year realized gains.

At December 31, 2025, the effect of permanent "book/tax" reclassifications resulted in increases and decreases to components of the Fund's net assets as follows:

Distributable earnings (losses)				$	4,249
Beneficial Interest					(4,249	)

ASC 740-10 "Income Taxes-Overall" sets forth a minimum threshold for financial statement recognition of the benefit of a tax position taken or expected to be taken. The Fund has conducted an analysis and concluded as of December 31, 2025, that there are no significant uncertain tax positions taken or expected to be taken that would require recognition in the financial statements. It is the Fund's policy to record any significant foreign tax exposures on the financial statements. The Fund recognizes interest and penalties, if any, related to uncertain tax positions as income tax expense in the Statement of operations. During the year ended December 31, 2025, the Fund did not incur any interest or penalties.

Each of the tax years in the four year fiscal period ended December 31, 2025, remains subject to examination by the Internal Revenue Service and state taxing authorities.

Report of independent registered public accounting firm

To the Shareholders and the Board of Trustees of
SMA Relationship Trust

Opinion on the Financial Statements

We have audited the accompanying statement of assets and liabilities of Series M (the "Fund") (the sole fund constituting SMA Relationship Trust (the "Trust")), including the portfolio of investments, as of December 31, 2025, the related statement of operations for the year then ended, the statements of changes in net assets for each of the two years in the period then ended, the financial highlights for each of the five years in the period then ended and the related notes (collectively referred to as the "financial statements"). In our opinion, the financial statements present fairly, in all material respects, the financial position of the Fund (the sole fund constituting SMA Relationship Trust) at December 31, 2025, the results of its operations for the year then ended, the changes in its net assets for each of the two years in the period then ended and its financial highlights for each of the five years in the period then ended, in conformity with U.S. generally accepted accounting principles.

Basis for Opinion

These financial statements are the responsibility of the Trust's management. Our responsibility is to express an opinion on the Fund'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 the Trust's 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 procedures included confirmation of securities owned as of December 31, 2025, by correspondence with the custodian and brokers; when replies were not received from brokers, we performed other auditing procedures. 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.

We have served as the auditor of one or more UBS investment companies since 1978.
