4 Letter to Shareholders April 25, 2018 Dear Fellow Shareholder: We are pleased to present the semi-annual report for Thornburg New Mexico Intermediate Municipal Fund. The net asset value (NAV) of the Class I shares decreased by 27 cents to $13.02 per share during the six-month period ended March 31, During the period, the Class I shares of the Fund outperformed the index with a negative 0.64% total return, compared to the negative 1.17% total return for the ICE BofAML 3-15 Year U.S. Municipal Securities Index. The Fund s duration, as well as curve positioning, was the largest driver of outperformance, adding 0.55% to relative performance. Sector selection was another driver of relative performance, adding 0.16%. Lastly, security selection, which is performance not attributable to duration and sector selection, added 0.17% to relative performance. The topic of tax reform consumed municipal market participants in the fourth quarter of 2017, with several proposals being bandied about that would significantly impact the supply/ demand dynamics of the market for years to come. Ultimately, the legislation was not as radical as initially feared. On the supply side of the equation, issuers lost the ability to advance refund debt. Much like a homeowner refinancing an existing mortgage to save on interest costs, an issuer would refinance debt when interest rates were low to provide some present value savings. While many thought this would have a large impact on supply, we did not agree. Advance refunding is highly correlated to the current level of interest rates, and many issuers had already accomplished any possible refunding over the previous several years. Instead, we found the impact of tax reform on the demand side of the equation to be far more interesting. What was overlooked was the reduction of the corporate tax rate from 35% to 21%, and the idea that corporations evaluating municipal bonds versus other fixed income securities on a tax equivalent basis would now require a higher hurdle rate to buy municipal securities. We felt that the impact this may have on two specific buyers of municipals, banks, and property and casualty insurance companies, which own roughly 20 to 25% of outstanding municipal bonds, could lead both to re-evaluate their decision to own municipal bonds. While we do not believe this to be an Armageddon type of scenario; we expect it to be more like a weight leaning on the market for the next 12 to 18 months. Another impact on the demand side is the limitations on the deductibility of state and local taxes (SALT), which has led many market observers to postulate that the demand for municipal bonds in high tax states will increase. Again, we did not share the same opinion. In California, the demand for California bonds has already driven prices to a level where we feel there is little value when compared to other municipal securities on a tax-equivalent basis. Demand for municipal securities in other high tax states, such as Connecticut, Pennsylvania, and New Jersey, is not as cut and dry because there is significant credit risk associated with each. Nevertheless, these concerns caused the supply of municipal bonds to spike in November and December as issuers rushed to market to hedge against the potential threat of tax reform. Some investors viewed this period as an opportunity to buy extra municipal bonds in anticipation of a January rally, which never materialized. We did not view the market the same way, and kept our strategies positioned at the lower end of their relative risk spectrums (i.e. lower duration, higher credit quality, and higher reserve positions). The last fear facing the municipal bond market is the long-advertised infrastructure plan. While the plan has experienced several failed launches, and what is known suggests it will have little impact on the supply of municipal bonds, we are still monitoring the details of the proposal for potential impacts to our strategies. The fourth quarter of 2017 saw yields of shorter maturity bonds increase more than the yields of longer maturity bonds, leading to a flattening of the yield curve. At the time, many analysts and pundits harped on the fact that the phenomenon portends a future recession. In the first quarter of 2018, the market watched as yields of longer maturity bonds increased more than yields of shorter maturity bonds, leading to a steepening of the yield curve. The steepening of the curve is an indication that market participants have a growing concern about increases in inflation the enemy of the fixed income investor. The Fund s conservative positioning was a headwind to performance in the fourth quarter of 2017, but acted as a tailwind to performance in the first quarter of Thank you for your continued trust in us.

Glossary The ICE BofAML 3-15 Year U.S. Municipal Securities Index is a subset of the ICE BofAML U.S. Municipal Securities Index including all securities with a remaining term to final maturity greater than or equal to 3 years and less than 15 years. The performance of any index is not indicative of the performance of any particular investment. Unless otherwise noted, index returns reflect the reinvestment of income dividends and capital gains, if any, but do not reflect fees, brokerage commissions or other expenses of investing. Investors may not make direct investments into any index. Annualized Distribution Yield The distribution yield reflects actual distributions made to shareholders. The annualized distribution yield is calculated by summing the last 30 days of income at a given month end and annualizing to a 360-day year. The result is divided by the ending maximum offering price or net asset value. SEC Yield A yield computed in accordance with SEC standards measuring the net investment income per share over a specified 30-day period expressed as a percentage of the maximum offering price of the Fund s shares at the end of the period. Advance refunding Advance refunding can also refer to bond issuance in which new bonds are sold at a lower rate than outstanding ones. The proceeds are then invested, and when the older bonds become callable, they are paid off with the invested proceeds. Bond Credit Ratings (Credit Quality) - A bond credit rating assesses the financial ability of a debt issuer to make timely payments of principal and interest. Rating of AAA (the highest), AA, A, and BBB are investment-grade quality. Rating of BB, B, CCC, CC, C and D (the lowest) are considered below investment grade, speculative grade, or junk bonds. Credit Spread/Quality Spread - The difference between the yields of securities with different credit qualities. Duration - A bond s sensitivity to interest rates. Bonds with longer durations experience greater price volatility than bonds with shorter durations. Effective duration incorporates a bond s embedded option features, such as call provisions. Laddering Laddering involves building a portfolio of bonds with staggered maturities so that a portion matures each year. Money that comes in from maturing bonds is typically invested in bonds with longer maturities at the far end of the portfolio. Yield Curve - A line that plots the interest rate, at a set point in time, of bonds having equal credit quality, but offering maturity dates. Semi-Annual Report 5

6 Fund Summary OBJECTIVES AND STRATEGIES The Fund s primary investment objective is to obtain as high a level of current income exempt from federal and New Mexico state individual income taxes as is consistent, in the view of the investment advisor, with preservation of capital. The secondary goal of the Fund is to reduce expected changes in its share price compared to long-term bond portfolios. This Fund offers New Mexico investors double tax-free yields (may be subject to Alternative Minimum Tax) in a laddered municipal bond portfolio with a dollar-weighted average maturity of normally three to 10 years. Laddering involves building a portfolio of bonds with staggered maturities so that a portion of the portfolio matures each year. Cash from maturing bonds, if not needed for other purposes, is typically invested in bonds with longer maturities at the far end of the ladder. We regard the strategy as a good compromise for managing different types of risk.

12 Notes to Financial Statements NOTE 1 ORGANIZATION Thornburg New Mexico Intermediate Municipal Fund (the Fund ) is a non-diversified series of Thornburg Investment Trust (the Trust ). The Trust was organized as a Massachusetts business trust under a Declaration of Trust dated June 3, 1987 and is registered as a diversified, open-end management investment company under the Investment Company Act of 1940, as amended. The Fund is currently one of twenty-one separate series of the Trust. Each series is considered to be a separate entity for financial reporting and tax purposes and bears expenses directly attributable to it. The Fund s primary investment objective is to obtain as high a level of current income exempt from federal and New Mexico state individual income tax as is consistent, in the view of Thornburg Investment Management, Inc., the Trust s investment advisor (the Advisor ), with the preservation of capital. The Fund s secondary objective is to reduce expected changes in its share price compared to long-term bond portfolios. The Fund currently offers three classes of shares of beneficial interest: Class A, Class D, and Institutional Class ( Class I ). Each class of shares of the Fund represents an interest in the same portfolio of investments, except that (i) Class A shares are sold subject to a front-end sales charge collected at the time the shares are purchased and bear a service fee, (ii) Class D shares are sold at net asset value without a sales charge at the time of purchase or redemption, and bear both a service fee and a distribution fee, (iii) Class I shares are sold at net asset value without a sales charge at the time of purchase and may be subject to a service fee, and (iv) the respective classes may have different reinvestment privileges and conversion rights. Additionally, the Fund may allocate among its classes certain expenses, to the extent allocable to specific classes, including transfer agent fees, government registration fees, certain printing and postage costs, and administrative and legal expenses. Currently, class specific expenses of the Fund are limited to service and distribution fees, administration fees, and certain registration and transfer agent expenses. The following is a summary of significant accounting policies followed by the Fund in the preparation of its financial statements. The Fund prepares its financial statements in conformity with United States generally accepted accounting principles ( GAAP ), including investment company accounting and reporting guidance in the Financial Accounting Standards Board (the FASB ) Accounting Standard Codification Topic 946. NOTE 2 SIGNIFICANT ACCOUNTING POLICIES Security Valuation: All investments in securities held by the Fund are valued as described in Note 3. Allocation of Income, Gains, Losses and Expenses: Net investment income (other than class specific expenses) and realized and unrealized gains and losses are allocated daily to each class of shares based upon the relative net asset value of outstanding shares (or the value of the dividend-eligible shares, as appropriate) of each class of shares at the beginning of the day (after adjusting for the current capital shares activity of the respective class). Expenses common to all Funds are allocated among the Funds comprising the Trust based upon their relative net asset values or other appropriate allocation methods. Operating expenses directly attributable to a specific class are charged against the operating income of that class. Dividends and Distributions to Shareholders: Dividends and distributions to shareholders, which are determined in accordance with federal income tax regulations and may differ from GAAP, are recorded on the ex-dividend date. Ordinary income distributions, if any, are declared daily and paid monthly. Capital gain distributions, if any, are declared and paid annually and more often if deemed necessary by the Advisor. Dividends are paid and are reinvested in additional shares of the Fund at net asset value per share at the close of business on the ex-dividend date, or at the shareholder s option, paid in cash. Investment Income: Interest income is accrued as earned. Premiums and discounts are amortized and accreted, respectively, to call dates or maturity dates using the effective yield method of the respective investments. These amounts are included in Interest income on the Statement of Operations. Custodian Fees: Custodian fees disclosed in the Statement of Operations may include interest expenses incurred by the Fund on any cash overdrafts of its custodian account during the period. Such cash overdrafts may result from the effects of failed trades in portfolio securities and from cash outflows resulting from unanticipated shareholder redemption activity. The Fund pays interest to its custodian on any such cash overdraft at a rate set periodically at the custodian s discretion of the overdraft amount in excess of $50,000. Investment Transactions: Investment transactions are accounted for on a trade date basis. Realized gains and losses from the sale of investments are recorded on an identified cost basis. When-Issued and Delayed Delivery Transactions: The Fund may engage in when-issued or delayed delivery transactions. To the extent the Fund engages in such transactions, it will do so for the purpose of acquiring portfolio investments consistent with the Fund s investment objectives and not for the purpose of investment leverage or to speculate on interest rate or market changes. At the time the Fund makes a commitment to purchase an investment on a when-issued or delayed delivery basis, the Fund will record the transaction and reflect the value in determining its net asset value. When effecting such transactions, assets of an amount sufficient to make payment for the portfolio 12 Semi-Annual Report

13 Notes to Financial Statements, Continued investments to be purchased will be segregated on the Fund s records on the trade date. Investments purchased on a when-issued or delayed delivery basis do not earn interest until the settlement date. Guarantees and Indemnifications: Under the Trust s organizational documents (and under separate agreements with the independent Trustees), its officers and Trustees are provided with an indemnification against certain liabilities arising out of the performance of their duties to the Fund. In the normal course of business the Trust may also enter into contracts with service providers that contain general indemnifications. The Trust s maximum exposure under these arrangements is unknown. However, based on experience, the Trust expects the risk of loss to be remote. Use of Estimates: The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of increases (decreases) in net assets from operations during the reporting period. Actual results could differ from those estimates. Federal Income Taxes: It is the policy of the Trust to comply with the provisions of the Internal Revenue Code applicable to regulated investment companies and to distribute to shareholders substantially all investment company taxable income including net realized gains on investments (if any), and tax exempt income of the Fund. Therefore, no provision for federal income or excise tax is required. The Fund files income tax returns in United States federal and applicable state jurisdictions. The statute of limitations on the Fund s tax return filings generally remains open for the three years following a return s filing date. The Fund has analyzed each uncertain tax position believed to be material in the preparation of the Fund s financial statements for the six month period ended March 31, 2018, including open tax years, to assess whether it is more likely than not that the position would be sustained upon examination, based on the technical merits of the position. The Fund has not identified any such position for which an asset or liability must be reflected in the Statement of Assets and Liabilities. At March 31, 2018, information on the tax components of capital was as follows: Cost of investments for tax purposes $ 170,461,293 Gross unrealized appreciation on a tax basis 4,714,316 Gross unrealized depreciation on a tax basis (1,516,468) Net unrealized appreciation (depreciation) on investments (tax basis) $ 3,197,848 At March 31, 2018, the Fund had deferred tax basis capital losses occurring subsequent to October 31, 2016 through September 30, 2017 of $100,189. For tax purposes, such losses will be recognized in the year ending September 30, At March 31, 2018, the Fund had cumulative tax basis capital losses of $1,154,384 (of which $87,413 are short-term and $1,066,971 are long-term) generated after September 30, 2011, which may be carried forward to offset future capital gains. To the extent such carryforwards are used, capital gain distributions may be reduced to the extent provided by regulations. Such capital loss carryforwards do not expire. NOTE 3 SECURITY VALUATION Valuation of the Fund s portfolio investment securities is performed in accordance with policies and procedures adopted by and under the oversight of the Trustees. The Trustees of the Trust have appointed the Advisor to assist the Trustees to obtain market values for portfolio investments, evaluate and monitor professional pricing service providers appointed by the Trustees Audit Committee (the Audit Committee ) to assist in determining fair values for portfolio investments, assist in calculating fair values for portfolio investments in certain circumstances, and to perform other functions in connection with the valuation of investments. The Advisor acts through its Valuation and Pricing Committee (the Committee ) and other employees of the Advisor. The Committee regularly reviews its own valuation calculations, as well as the valuations, valuation techniques and services furnished by pricing service providers, considers circumstances which may require valuation calculations by the Committee, and reviews previous valuation calculations. The Committee reports to the Audit Committee on the Committee s activities, the performance of pricing service providers, and other matters relating to valuation of portfolio investments. In those instances when the Committee assists in calculating a fair value for a portfolio investment, the Committee seeks to determine the price that the Fund would reasonably expect to receive upon a sale of the investment in an orderly transaction between market participants on the valuation date. The Committee customarily utilizes quotations from securities broker dealers in calculating valuations, but also may utilize prices obtained from pricing service providers or other methods approved by the Audit Committee. Because fair values calculated by the Committee are estimates, the calculation of a value for an investment may differ from the price that would be realized by the Fund upon Semi-Annual Report 13

14 Notes to Financial Statements, Continued a sale of the investment, and the difference could be material to the Fund s financial statements. The Committee s calculation of a fair value for an investment may also differ from the prices obtained by other persons (including other mutual funds) for the investment. Valuation of Securities: Debt obligations held by the Fund which are not listed or traded on exchanges or for which no reported market exists are ordinarily valued at the valuation obtained from a pricing service provider approved by the Audit Committee. In any case when a pricing service provider fails to provide a valuation for a debt obligation held by the Fund, the Committee calculates a fair value for the obligation using alternative methods under procedures approved by the Audit Committee. Additionally, in cases when management believes that a valuation obtained from a pricing service provider merits review for significant reasons, the Committee decides whether or not to use the valuation calculated by the pricing service provider or to use an alternative method approved by the Audit Committee to calculate a fair value for the obligation. Valuation Hierarchy: The Fund categorizes its investments based upon the inputs used in valuing those investments, according to a three-level hierarchy established in guidance from the FASB. Categorization of investments using this hierarchy is intended by the FASB to maximize the use of observable inputs in valuing investments and minimize the use of unobservable inputs by requiring that the most observable inputs be used when available. Observable inputs are those that market participants would use in valuing an investment based on available market information. Unobservable inputs are those that reflect assumptions about the information market participants would use in valuing an investment. An investment s level within the hierarchy is based on the lowest level input that is deemed significant to the valuation. The methodologies and inputs used to value investments are not necessarily indications of the risk or liquidity associated with those investments. Various inputs are used in calculating valuations for the Fund s investments. These inputs are generally summarized according to the three-level hierarchy below: Level 1: Quoted prices in active markets for identical investments. Level 2: Other direct or indirect significant observable inputs (including quoted prices for similar investments in active markets and other observable inputs, such as interest rates, prepayment rates, credit risk, etc.). Level 3: Significant unobservable inputs (including the Committee s own assumptions in calculating the fair values of investments). Valuations for debt obligations held by the Fund are typically calculated by pricing service providers approved by the Audit Committee and are generally characterized as Level 2 within the valuation hierarchy. In a limited number of cases the Committee calculates a fair value for investments using broker quotations or other methods approved by the Audit Committee. When the Committee uses a single broker quotation to calculate a fair value for an investment without other significant observable inputs, or if a fair value is calculated using other significant inputs that are considered unobservable, the investment is characterized as Level 3 within the hierarchy. Other significant unobservable inputs used to calculate a fair value in these instances might include an income-based valuation approach which considers discounted anticipated future cash flows from the investment and application of discounts due to the nature or duration of any restrictions on the disposition of the investment. Valuations based upon the use of inputs from Levels 1, 2 or 3 may not represent the actual price received upon the disposition of an investment, and the Fund may receive a price that is lower than the valuation based upon these inputs when it sells the investment. The following table displays a summary of the fair value hierarchy measurements of the Fund s investments as of March 31, In any instance when valuation inputs from more than one level are used to determine the fair value of a specific investment, the investment is placed in the level of the table based upon the lowest level input that is significant in determining the fair value of the investment: FAIR VALUE MEASUREMENTS AT MARCH 31, 2018 TOTAL LEVEL 1 LEVEL 2 LEVEL 3 Assets Investments in Securities Municipal Bonds $ 173,659,141 $ $ 173,659,141 $ Total Investments in Securities $ 173,659,141 $ $ 173,659,141 $ In accordance with the guidance prescribed in Accounting Standards Update No , it is the policy of the Fund to recognize transfers between levels and the underlying events which caused the movement. The Fund recognized no transfers between levels for the six months ended March 31, Semi-Annual Report

The Trust has entered into administrative service agreements with the Advisor, whereby the Advisor will perform certain administrative services related to each class of the Fund s shares. Until January 31, 2018, the fees were payable at an annual rate of up to of 1% per annum of the average daily net assets attributable to each class of shares. As of February 1, 2018, the fees are computed as an annual percentage of the aggregate average daily net assets of all shares classes of all Funds in the Trust as follows: ADMINISTRATION FEE SCHEDULE DAILY NET ASSETS FEE RATE Up to $20 billion 0.100% $20 billion to $40 billion $40 billion to $60 billion Over $60 billion The aggregate fee amount is allocated on a daily basis to each Fund based on net assets and subsequently allocated to each class of shares of the Fund. Total administrative service fees incurred by each class of shares of the Fund for the six months ended March 31, 2018, are set forth in the Statement of Operations. The Trust has an underwriting agreement with Thornburg Securities Corporation (the Distributor ), an affiliate of the Advisor, which acts as the distributor of the Fund s shares. For the six months ended March 31, 2018, the Distributor has advised the Fund that it earned net commissions aggregating $42 from the sale of Class A shares. Pursuant to a service plan under Rule 12b-1 of the Investment Company Act of 1940, the Fund may pay to the Distributor or securities dealers and other financial institutions at the Distributor s direction an amount not to exceed.25 of 1% per annum of the average daily net assets attributable to Class A and Class D shares of the Fund to obtain various shareholder and distribution related services. For the six months ended March 31, 2018, there were no 12b-1 service plan fees charged for Class I shares. The Advisor and the Distributor each may pay out of its own resources additional expenses for distribution of the Fund s shares and shareholder services. The Trust has also adopted a distribution plan pursuant to Rule 12b-1, applicable only to the Fund s Class D shares under which the Fund compensates the Distributor for services in promoting the sale of Class D shares of the Fund at an annual rate of up to.25 of 1% per annum of the average daily net assets attributable to Class D shares. Total fees incurred by each class of shares of the Fund under their respective service and distribution plans for the six months ended March 31, 2018, are set forth in the Statement of Operations. For the six months ended March 31, 2018, the Advisor reimbursed certain class specific expenses, administrative fees, and distribution fees of $195 for Class D shares and $1,103 for Class I shares. Certain officers and Trustees of the Trust are also officers or directors of the Advisor and Distributor. The compensation of the independent Trustees is borne by the Trust. The Trust also pays a portion of the Chief Compliance Officer s compensation. These amounts are reflected as Trustee and officer fees in the Statement of Operations. The percentage of direct investments in the Fund held by the Trustees, officers of the Trust, and the Advisor is approximately 12.01%. Semi-Annual Report 15
