Financial highlights

The table below sets forth financial data for one unit of beneficial interest outstanding throughout each period presented.

¹​ Calculated using the average shares method.

²​ Total investment return is calculated assuming a $10,000 investment on the first day of each period reported, reinvestment of all dividends and distributions, if any, at net asset value on the ex-dividend dates, and a sale at net asset value on the last day of each period reported. Total investment return for periods of less than one year has not been annualized. Returns do not reflect the deduction of taxes that a shareholder would pay on Fund dividends/distributions or the redemption of Fund shares.

³​ Annualized.

⁴​ The calculation of the portfolio turnover rate excludes transactions involving variable-rate demand notes, which are considered short-term instruments due to the ability to demand immediate repayment.

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"), (formerly, UBS Asset Management (Americas) Inc.), is the investment advisor and administrator for the Fund. UBS Asset Management (US) Inc. ("UBS AM (US)") serves as 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.

In October 2022, the SEC adopted the Tailored Shareholder Reports for Mutual Funds and Exchange-Traded Funds rule and reform amendments requiring open-end management investment companies, including mutual funds and exchange-traded funds, to transmit concise and visually engaging semi-annual and annual tailored shareholder reports that highlight key information, including fund expenses, performance, and holdings to shareholders. Certain information from the Fund's current shareholder reports, including the Fund's investment portfolio, financial statements and financial highlights, will not appear in the tailored shareholder report but will be filed on a semiannual basis on Form N-CSR. This information will be available online, mailed upon request and filed on a semiannual basis. The rule and form amendments have a compliance date of July 24, 2024.

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 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

SMA Relationship Trust-Series M

Notes to financial statements (unaudited)

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 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

SMA Relationship Trust-Series M

Notes to financial statements (unaudited)

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

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 June 30, 2024, 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 June 30, 2024, 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.

Interest on amounts borrowed is calculated based on prevailing rates in effect at the time of borrowing. The Advisor has agreed to pay commitment fees on the average daily balance of the Committed Credit Facility not utilized by the Fund. Commitment fees have been allocated among the funds 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 June 30, 2024, the Fund did not borrow under the Committed Credit Facility.

Purchases and sales of securities

For the period ended June 30, 2024, aggregate purchases and sales of portfolio securities, excluding short-term securities, were $109,179,573 and $59,906,488, 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:

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, 2023 was as follows:

The tax character of distributions paid and the components of accumulated earnings (deficit) on a tax basis for the current fiscal year will be determined after the Fund's fiscal year ending December 31, 2024.

Aggregate cost for federal income tax purposes, including derivatives (if any), was $ 414,101,142; and net unrealized appreciation (depreciation), including derivatives (if any) consisted of:

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. At December 31, 2023, losses incurred that will be carried forward indefinitely are as follows:

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 June 30, 2024, 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 in 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 period ended June 30, 2024, the Fund did not incur any interest or penalties.

Each of the tax years in the four year period ended December 31, 2023, remains subject to examination by the Internal Revenue Service and state taxing authorities.

February 27, 2024 Meeting

At the meeting of the Board of Trustees (the "Board") of SMA Relationship Trust (the "Trust"), held on February 27, 2024 (the "February Meeting"), the Board, including those Trustees who are not "interested persons" (as defined in the Investment Company Act of 1940, as amended (the "1940 Act")) of the Trust or UBS Asset Management (Americas) Inc. (the "Advisor" or "UBS AM")) and its affiliates (together, the "Independent Trustees"), considered an amendment (the "Amendment") to the investment advisory agreement (the "Advisory Agreement") between the Trust and the Advisor for Series M (the "Fund").

At the February Meeting, the Advisor reported that the Board was being asked to approve the Amendment to the Advisory Agreement relating to the Fund to reflect the proposed reorganization of the Advisor from a Delaware corporation to a Delaware limited liability company (the "Reorganization"). The Advisor reported that in June 2023, UBS Group AG ("UBS") acquired Credit Suisse Group AG ("Credit Suisse") and that as part of the integration of Credit Suisse into UBS, UBS AM will merge or otherwise consolidate with Credit Suisse Asset Management, LLC ("CSAM"). To facilitate the consolidation of UBS AM and CSAM, the Advisor reported that it will effect the Reorganization through a change of its form of organization from a corporation to a limited liability company organized under the laws of the state of Delaware in a conversion pursuant to Delaware statute and to a change in its name to UBS Asset Management (Americas) LLC.

The Advisor represented, and the Board considered, that the Reorganization will involve no change to: (i) the investment processes and strategies employed in the management of the Fund's assets; (ii) the nature and level of services provided to the Fund; (iii) the individuals primarily responsible for the day-to-day management of Fund assets; or (iv) the trustees and officers of the Fund. The Advisor further reported that the personnel who primarily provide investment management services to the Fund pursuant to the Advisory Agreement prior to the Reorganization will continue to serve in such roles immediately after the Reorganization. It was noted that the Amendment contains no

changes to the Advisory Agreement other than to reflect UBS AM's new name and form of organization resulting from the Reorganization, and all other provisions of the Advisory Agreement would remain in full force and effect, including that no investment advisory fee is charged under the Agreement. Accordingly, the Board considered the information provided in connection with its prior review of the renewal of the Advisory Agreement in considering the approval of the Amendment.

After full consideration of the information discussed above, the Board, including a majority of the Independent Trustees, with the assistance of independent counsel, concluded that the approval of the Amendment to the Advisory Agreement for the Fund was in the interests of the Fund and its shareholders.

June 6-7, 2024 Meeting

At the meeting of the Board of Trustees (the "Board") of SMA Relationship Trust (the "Trust"), held on June 6 and 7, 2024 (the "Meeting"), the Board, including those Trustees who are not "interested persons" (as defined in the Investment Company Act of 1940, as amended (the "1940 Act")) of the Trust or UBS Asset Management (Americas) LLC (the "Advisor") and its affiliates (together, the "Independent Trustees"), considered the continuation of the investment advisory agreement (the "Advisory Agreement") between the Trust and the Advisor for Series M, a series of the Trust (the "Fund"). Prior to the Meeting, the Independent Trustees' counsel had sent to the Advisor a request detailing the information that the Independent Trustees wished to receive in connection with their consideration of the continuation of the Advisory Agreement. The Independent Trustees met with their independent counsel, as well as an independent consultant engaged by the Board to assist in the annual Advisory Agreement review process, on May 28, 2024 and June 6, 2024 to discuss the materials provided to them in response to the information request, including materials prepared by the Advisor, as well as reports prepared by Broadridge Financial Solutions, Inc. ("Broadridge Reports"), an independent statistical compilation company, providing comparative expense and performance information for the Fund. The Independent Trustees also reviewed information provided in response to their request for additional information from the Advisor in connection with the Advisory Agreement. The Board also made reference to information and material that had been provided to the Independent Trustees throughout the year at Board meetings.

At the Meeting, the Board considered a number of factors in connection with its deliberations concerning the continuation of the Advisory Agreement for the Fund, including: (i) the nature, extent, and quality of the services provided by the Advisor to the Fund; (ii) the performance of the Fund and the Advisor; (iii) the Fund's expenses, costs of the services to be provided and profits to be realized by the Advisor and its affiliates from the relationship with the Fund; and (iv) whether economies of scale are realized by the Advisor with respect to the Fund, as it grows larger, and the extent to which the economies of scale are reflected in the level of the management fees charged.

Nature, extent, and quality of services. In considering the nature, extent, and quality of the services provided by the Advisor to the Fund, the Board reviewed the material presented by the Advisor describing the various services provided to the Fund. The Board noted that in addition to investment management services, the Advisor provides the Fund with operational, legal, and compliance support. The Board also considered the scope and depth of the Advisor's organization and the experience and expertise of the professionals currently providing investment management and other services to the Fund. The Board considered that the Advisor was a well-established investment management organization employing investment personnel with significant experience in the investment management industry. The Board also considered that, effective May 1, 2024, the Advisor acquired Credit Suisse Asset Management, LLC. The Board considered that this transaction has increased the Advisor's asset management capabilities, expanded the Advisor's presence in key markets, and broadened the Advisor's product offerings. The Board also considered the Advisor's in-house research capabilities, as well as other research services available to it, including research services available to the Advisor as a result of securities transactions effected for its clients, and noted that the Advisor had extensive global research capabilities.

The Board also evaluated the Advisor's portfolio management process for the Fund, including the use of risk management techniques and the proprietary technologies utilized to structure the Fund's portfolio. The Board noted that various presentations had been made by investment personnel at Board meetings throughout the year concerning the Fund's investment performance and investment strategies.

The Board also noted and discussed the services that the Advisor and its affiliates provide to the Fund under other agreements with the Trust, including administration services provided by the Advisor and underwriting services provided by UBS Asset Management (US) Inc. In connection with the non-investment management services, the Board also considered the quarterly reports that the Advisor provides to the Board throughout the year pertaining to portfolio valuations, among other matters. The Board noted management's continuing endeavors and expenditures to address areas of heightened concern in the mutual fund industry and comply with new regulations applicable to the Fund, such as business continuity testing following Russia's invasion of Ukraine, compliance with the SEC's new "tailored shareholder report" requirements, proxy vote reporting and the Rule 35d-1 (names rule) amendments. After analyzing the services provided by the Advisor to the Fund, both quantitatively and qualitatively, including the impact of these services on investment performance, the Board concluded that the nature, extent, and quality of services provided to the Fund were consistent with the operational requirements of the Fund, and met the needs of the Fund's shareholders.

Performance. In evaluating the performance of the Fund, the Board analyzed the Broadridge Reports, which compared the performance of the Fund with other funds in its peer universe over various time periods. The Board also reviewed the memoranda provided by the Advisor providing an analysis of the markets and the Fund's performance during the past year. In reviewing the Broadridge Reports, the Board noted that Series M had appeared in the fourth performance quintile and had annualized total return below the median of its peer universe for the one-year performance period ended February 29, 2024. The Advisor explained the performance of the Fund for the one-year performance period ended February 29, 2024, noting that the Fund's shorter effective duration contributed to its underperformance compared to its peers. The Advisor also noted that while the Fund's performance was below the performance universe median for the one-year period, the Fund was in the 2nd quintile of the performance universe for the three-year period ended February 29, 2024, and the 1st quintile of the performance universe for both the five-year period and ten-year period ended February 29, 2024.

The Board determined, after analyzing the performance data, that the performance of the Fund was acceptable as compared with relevant performance standards, given the investment strategies and risk profile of the Fund, the expectations of the shareholder base and the current market environment.

Costs and expenses. The Board noted that the Fund does not pay advisory fees to the Advisor under the Advisory Agreement and that the Advisor assumes all the ordinary operating expenses for the Fund.

Profitability. In considering the profitability of the Fund to the Advisor and its affiliates, the Board noted that neither the Advisor nor its affiliates receive any compensation for providing advisory or administrative services to the Fund. The Board also considered "fall-out" or ancillary benefits to the Advisor or its affiliates as the result of their relationship with the Fund; for example, the ability to attract other clients due to the Advisor's role as investment advisor to the Fund, including the investment by wrap fee clients in the Fund as a means to deliver certain investment styles. Upon closely examining the information provided concerning the Advisor's profitability, the Board concluded that the level of profits realized by the Advisor and its affiliates with respect to the Fund, if any, was reasonable in relation to the nature and quality of the services that were provided.

Economies of scale. The Board also discussed whether economies of scale are realized by the Advisor with respect to the Fund as it grows larger, and the extent to which this is reflected in the level of advisory fees charged. The Board concluded that economies of scale and the reflection of such economies of scale in the level of advisory fees charged were inapplicable to the Fund because the Fund was not charged an advisory fee under its Advisory Agreement.

After full consideration of the factors discussed above, with no single factor identified as being of paramount importance, the Board, including a majority of the Independent Trustees, with the assistance of independent counsel, concluded that the continuation of the Advisory Agreement for the Fund was in the interests of the Fund and its shareholders.
