Investments carry risks, including possible loss of principal. Additional risks may be associated with investments outside the United States, especially in emerging markets, including currency fluctuations, illiquidity, volatility, and political and economic risks. Investments in small- and mid-capitalization companies may increase the risk of greater price fluctuations. Portfolios investing in bonds have the same interest rate, inflation, and credit risks that are associated with the underlying bonds. The value of bonds will fluctuate relative to changes in interest rates, decreasing when interest rates rise. A short position will lose value as the security’s price increases. Theoretically, the loss on a short sale can be unlimited. Investments in derivatives are subject to the risks associated with the securities or other assets underlying the pool of securities, including illiquidity and difficulty in valuation. Please see the Funds’ prospectus for a discussion of the risks associated with an investment in the Funds. Investments in the Funds are not FDIC insured, nor are they deposits of or guaranteed by a bank or any other entity.

Letter to Shareholders
September 30, 2020 (Unaudited)

Dear Shareholder:

As we all continue to navigate unprecedented conditions, both in the market and in our daily lives, I want to assure you that we at Thornburg Investment Management continue to be focused on providing all of our clients excellent outcomes. The last seven months have been an excellent proof point for Thornburg’s approach to the market. Our nimble, collaborative firm was largely able to adapt to a very different environment, again both in markets and in our operational infrastructure. We have experienced a number of different challenges over the course of the firm’s nearly four-decade history. That experience has informed the construction and evolution of our firm, including the structure of the investment team, to be successful in the context of difficult times.

So where do we go from here? As I write, we’re only a few days away from what looks to be a very consequential election, not just for the U.S. but for the globe. That said, regardless of the outcome, we expect continued volatility, given the effect of extraordinary economic stimulus, a continued slow, unsteady recovery and an uncertain policy pathway in response to the COVID-19 health crisis. Globally, low risk-free rates present a challenge for investors in several ways. First, safe haven assets like U.S. Treasuries are priced to provide a negative real (or after-inflation) yield, due to purchases by the Federal Reserve to engineer particular economic outcomes. Second, asset allocation methodology assumes a negative correlation between risky assets and high-quality bonds, but very low yields make this calculus much more challenging. Third, even if lower rates were possible, the amount of additional stimulus to be gained by such outcomes is fairly low: we’ve pulled forward a tremendous amount of growth and demand already.

Our benchmark agnostic, flexible approach should continue to serve us well as we have the ability to go where we can find value, within the mandate and objectives of each portfolio. Combined with our focus on breaking down silos within the investment universe, we are designed to see the world with better perspective. Many firms have good products, but we believe that our differentiated process, evaluating individual opportunities with a clear understanding of the bigger picture, underlies the excellent long-term outcomes we’ve been able to deliver.

We certainly don’t know what will happen over the coming weeks and months, but we’re excited about continued opportunities to deliver for you, given what we see as a rapidly

changing market. Some of those changes are cyclical, and we will do our best to see through the cycle, but some changes are secular, and an unexamined acceptance of past truths will be unprofitable at best and dangerous at worst. It is our understanding of and participation in the interconnectedness of markets that is our core competency: We’re built for this.

Thank you so much for your time, and your business.

Thornburg Investment Income Builder Fund |

September 30, 2020 (Unaudited)

Dear Fellow Shareholder:

This letter will highlight the basic results of your Fund’s investment portfolio for the 12-month period ended September 30, 2020. Your Fund’s fiscal year ended on September 30. In addition, we will comment on the overall investment landscape, which has been evolving rapidly amidst the extraordinary developments associated with the global spread of COVID-19.

Thornburg Investment Income Builder Fund paid ordinary dividends of $0.943 per Class I share in fiscal year ended September 30, 2020. This was approximately 5% below the dividend of $0.993 for fiscal 2019. The dividend per share was lower for Class A and Class C shares, to account for varying class-specific expenses.

The net asset value of the Class I shares decreased by $3.04 per share ($21.88 to $18.84) over the fiscal year ending September 30, 2020. Importantly, the net asset value decreased by $6.53 per share in the 41 days from February 19 to March 31 as the COVID-19 pandemic gained momentum globally and set off a chain reaction of selling across a range of financial assets. The selling wave was significantly reversed beginning in the final week of March with respect to government bonds, government agency bonds and high-grade corporate bonds as the U.S. Federal Reserve (and other central banks) bought these instruments with newly printed money, followed promptly by additional buying from private investors. Private investors also piled into certain “growth” equities, funding these purchases in part by selling dividend-paying equities. The net asset value of your Fund was $16.61 per share as of March 31, 2020, and increased by $2.23/share to $18.84 over the six-month period ending September 30, 2020.

We believe Thornburg Investment Income Builder is a bargain priced portfolio of income-producing assets that should be capable of generating additional price appreciation along with income in the coming years. Listed below in descending order are the 25 largest equity holdings in the Fund at September 30, along with 2020 year-to-date returns. Also noted are dividend yields at closing September 30, 2020 stock prices. Sixteen of these 25 firms have seen share price declines in 2020 to date. Together, these 25 firms comprise approximately 64% of the Fund’s total assets. Cash & interest-bearing debt comprise around 18% of assets, and 31 other common equities and three preferred equities comprise a total of approximately 18% of assets. Individual position sizes range from 5.0% (Taiwan Semiconductor) to approximately 1.3% for those shown near the bottom of the list.

These are not trivial businesses. These firms occupy important positions in their respective markets, and they tend to be well capitalized. The reader will notice a significant number of telecommunications, communications infrastructure, financial

and health care firms among these top 25 holdings, as well as other providers of various ingredients important to modern life. Aside from the fact that they have paid attractive dividends, the current crisis reinforces the essential nature of the products and services they provide.

Thornburg Investment Income Builder Fund – Top 25 Equity Holdings as of September 30, 2020

(Together, these 25 investments account for approximately 64% of assets as of September 30, 2020; cash & interest-bearing debt diversified across approximately 200 debt instruments comprise 18% of assets, and 34 other equity investments account for 18% of assets).

Letter to Shareholders, Continued
September 30, 2020 (Unaudited)

The 32 equity investments shown below comprised approximately 18% of your Fund’s total net assets as of September 30, 2020. Some of these are non-cyclical businesses (electric utilities Electricite de France and E.ON, or telecommunications network operators China Telecom, KPN and Singapore Telecommunications). Others are cyclical businesses that have paid attractive dividends in recent years (investment managers M&G and UBS), non-bank financials trading at discounts to their net asset values (Chimera Investment, MFA Financial, Solar Capital), industrial materials producers that should benefit from any 2021 economic recovery (Glencore, LyondellBasell), or industrial conglomerate Siemens. In general, share prices of the cyclical businesses in the Income Builder portfolio declined more than the entire portfolio during fiscal 2020.

Share prices of certain large firms with “growth” narratives have been bid higher over the last six months. Most dividend-paying stocks have been left behind in the recent rotation of investor dollars into bank deposits, bonds, and growth stocks. We believe this will change, though it is difficult to predict timing. We have increased your portfolio’s exposure to dividend-paying firms that we believe have resilient businesses with strong capital structures, particularly in the information technology, communications services, and health care sectors. We have reduced or eliminated exposures to less resilient businesses, particularly in the energy, materials and industrials sectors. Compare the sector allocations of the equities in the Income Builder portfolio over the course of the fiscal year:

Investment Income Builder’s bond holdings overall delivered positive returns during the period under review. U.S. government bond prices increased significantly as 10-year U.S. Treasury yields dropped from 1.66% to 0.68%. Corporate bond prices were generally higher, as the yield on the Bloomberg Barclays U.S. Corporate Bond Index declined from 2.91% to 2.01% over the fiscal year. The Bloomberg Barclays Global Aggregate Bond Index, which is comprised of some $65 trillion of investment grade bonds from both developed market and emerging market issuers with a weighted average maturity of 9.1 years, carried a yield to lower of call/maturity of 0.92% as of October 9, 2020.

Eleven of Thornburg Investment Income Builder’s 12 largest equity holdings have traded debt issues outstanding as of October 2020. The following table compares equity dividend yields from these issuers with their debt yields, citing specific debt issues of these firms and their market yields indicated by Bloomberg. The reader will note that in every case the dividend yields exceed the debt yields, typically by significant margins.

Investment Income Builder’s Class I share return of negative 9.55% for the 12-month period ending September 30, 2020 trailed its blended benchmark (75% MSCI World Index and 25% Bloomberg Barclays U.S. Aggregate Bond Index), which returned 10.1% for the period. We have described many of the individual ingredients of your Fund’s fiscal year 2020 performance in the preceding paragraphs. The benchmark benefited significantly from (i) central bank support for the bond component of the blended index in the last half of the fiscal year, and (ii) the fact that six of the seven largest holdings of the equity portion of the benchmark are technology giants whose share prices have performed relatively well, but pay low dividends or no dividends (Microsoft, Apple, Amazon, Facebook, Alphabet/Google and Alibaba). Performance comparisons of Investment Income Builder to its blended benchmark over various periods are shown elsewhere in this report.

The quarter ending September 30, 2020 was the 71st full calendar quarter since the inception of Thornburg Investment Income Builder in December 2002. In 53 of these quarters the Fund delivered a positive total return. The Fund has delivered positive total returns in 14 of its 17 calendar years of existence.

Although no central banks have been bidding up prices of most of the assets in your Investment Income Builder portfolio, we are optimistic about the future return potential of these assets. Why? Virtually all the businesses in your portfolio retain their market positions providing important products and services that generate cash flows to pay attractive dividends. If high-quality bond yields, bank deposit yields and money market yields remain at low levels in line with the guidance of major global central banks, we believe investors will direct capital into

dividend-paying stocks and certain bonds, supporting prices of these investments.

Readers of this commentary who are long-time shareholders of Income Builder will recall that the interest-bearing debt portion of the Fund’s portfolio has varied over time, ranging from less than 9% in 2015 to 45% at June 30, 2009. We tend to allocate more portfolio assets to interest-bearing debt when yields are more attractive. In the September 2020 fiscal year, more than 85% of Income Builder’s income was derived from stock dividends, the remainder coming from interest.

We believe the extreme dislocation caused by the COVID-19 pandemic will be temporary. As we write these words, a portion of the global population remains under some type of “restricted activity” order that reduces normal economic activity. When the COVID-19 pandemic passes, we believe people around the world will continue to buy goods and services and trade with each other. The global economy will gradually repair, albeit with important differences. In the meantime, most governments will make reasonable attempts to bridge the material dislocations we currently witness.

Thornburg Global Opportunities Fund |

September 30, 2020 (Unaudited)

Dear Fellow Shareholder:

This letter will highlight the results of the Thornburg Global Opportunities Fund investment portfolio for the 12-month period ended September 30, 2020. Your Fund’s fiscal year ended on September 30.

The net asset value of the Class I shares increased by $4.14 per share ($27.67 to $31.81) during the annual period under review. In addition, we paid $0.51 per share of dividend with respect to the Class I shares, bringing the total return for the 12- month period to 16.91%, a positive advantage of 6.47% vis-a-vis its benchmark index (MSCI All Country World Index), which returned 10.44% for the period. Dividend amounts for other classes of Fund shares varied based on class-specific expenses.

Your Fund’s returns for the two halves of fiscal year 2020 were quite different. Your Fund returned negative 13.85% for the six-month period from October 1, 2020 to March 31, 2020, reflecting much of the initial COVID-19 related panic in the last weeks of that period. Your Fund returned 35.71% for the six-month period from April 1, 2020 to September 30, 2020 as most businesses in the portfolio demonstrated resilience.

Most equities in the Thornburg Global Opportunities Fund recovered strongly in the June and September quarters from their March 2020 price troughs, as the following list will describe. Listed below in descending order are the 20 largest equity holdings in the Fund as of September 30, 2020, along with calendar 2020 year-to-date returns as of 9/30/20 and 3/31/20 [the latter in parentheses]. We also show the trailing five-year annual revenue growth rates for these businesses through year end 2019, or the latest reported fiscal year end. Even with share price recoveries in the June and September quarters, seven of these 20 largest equity investments have delivered negative returns in calendar 2020 through 9/30/2020. We believe observed operating results from these businesses will justify better future returns.

Individual position sizes of the Fund’s top 20 positions range from approximately 5% or more (Reliance Industries, Alibaba, Vestas Wind Systems, Qorvo and Samsung Electronics) to just over 2.4% for those shown near the bottom of this list. The reader will notice a high incidence of investments in firms tied to the digital economy, and to tools to facilitate digital communications.

These are not trivial businesses. They tend to be well capitalized. We believe most of these will emerge from the present economic valley with their competitive positions intact or improved. Most have been growing faster than the global economy in recent years as the trailing annual revenue growth rates indicate. Some of the slower growers over recent years appear to be advantaged in their industries at this time.

Thornburg Global Opportunities Fund – Top 20 Equity Holdings as of September 30, 2020

(Together, these 20 investments accounted for approximately 77% of Fund assets as of September 30, 2020; near cash interest bearing debt accounted for 7% of assets, and 10 other equity investments accounted for around 16% of Fund assets).

Thornburg Equity Funds Annual Report | 9

Letter to Shareholders, Continued
September 30, 2020 (Unaudited)

Performance comparisons of Thornburg Global Opportunities Fund to its benchmark over various periods are shown elsewhere in this report. In July of 2020 we marked the 14th anniversary of the Fund’s inception. From its inception on July 28, 2006, through September 30, 2020, Thornburg Global Opportunities Fund has outpaced the ACWI by an average margin of over 3.0% per year, resulting in a total cumulative return since inception of 244.7% (Class I shares) versus 150.9% for the ACWI index.

The following table summarizes major sector weightings within the Global Opportunities Fund portfolio as of September 30, 2020 and one year earlier. The reader will notice a decrease in portfolio exposure to more cyclical industrials and materials sector firms in favor of increased exposure to technology, consumer discretionary and health care sector firms. Your Fund’s increased exposure to financial firms year on year reflects bargain hunting in an unloved sector that has delivered more resilient results than it is being given credit for.

During the 2020 fiscal year, 20 of your Fund’s equity investments contributed at least 0.25% to overall portfolio performance. Twelve investments detracted at least negative 0.25% from portfolio performance. The top six contributors to portfolio performance included Danish wind turbine manufacturer Vestas Wind Systems, India’s energy and digital communications conglomerate Reliance Industries, Chinese data center operator GDS Holdings, integrated circuit provider Qorvo, Indonesian online gaming and digital commerce firm

Sea Ltd, and China’s digital marketplace operator Alibaba Group Holdings. We sold Sea Ltd from the portfolio when its share price exceeded our target. We retain investments in the other five top FY 2020 contributors.

The six greatest detractors from portfolio performance included Netherlands-based fertilizer manufacturer OCI NV, multinational financial services conglomerate Citigroup, Italy-based toll road and airport operator Atlantia, Brazil’s integrated oil producers Petroleo Brasileiro, U.S. consumer bank Capital One and European regional airline easyJet Plc. We sold Atlantia, Petrobras and easyJet from the portfolio to reduce COVID-19 related business risks and make room for other opportunities.

We believe the extreme dislocation caused by the COVID-19 pandemic will be temporary. As we write these words many countries, including parts of the United States, remain under restrictive orders that reduce normal economic activity. When the COVID-19 pandemic passes, we believe people around the world will continue to buy goods and services and trade with each other, though there will be certain differences from prior norms. The global economy will gradually repair. In the meantime, most governments will make reasonable attempts to bridge the material dislocations we currently witness.

Our Investment Framework

Thornburg Global Opportunities Fund seeks capital appreciation from a portfolio of global equity investments. We believe the structure of the Fund—built on our core investment principles of flexibility, focus, and value—provides a durable framework for value-added investing.

We urge shareholders of the Fund to maintain a long-term investment perspective rather than placing too much emphasis on return figures that are available daily, weekly, monthly and quarterly. We continue to follow our core investment principles of flexibility, focus, and value, as we have since the Fund’s inception back in 2006.

Thank you for being a shareholder of Thornburg Global Opportunities Fund. Remember that you can monitor the holdings of Thornburg Global Opportunities Fund and other information respecting your Fund on our website, www.thornburg.com.

Thornburg Investment Income Builder Fund

Investment Goal and Fund Overview

The Investment Income Builder Fund’s primary investment goal is to provide a level of current income which exceeds the average yield on U.S. stocks generally, and which will generally grow, subject to periodic fluctuations, over the years on a per share basis. The Fund’s secondary investment goal is long-term capital appreciation.

The Fund pursues its investment goals by investing in a broad range of income producing securities, primarily stocks and bonds. Equity investments normally will be weighted in favor of companies which pay dividends. The Fund may invest in securities of issuers domiciled in or economically tied to countries outside the United States, including developing countries. Investment decisions are based on domestic and international economic developments, outlooks for securities markets, interest rates and inflation, the supply and demand for debt and equity securities, and analysis of specific issuers.

See letter beginning on page 5 of this report for a discussion of factors affecting the Fund’s performance for the reporting period ended September 30, 2020.

Thornburg Summit Fund

Investment Goal and Fund Overview

The Summit Fund seeks to grow real wealth over time. “Real wealth” for this purpose is a mix of capital appreciation and current income that is intended to exceed the rate of inflation. Under normal conditions the Fund’s investments are expected to emphasize long positions in equity securities and fixed income obligations, though the Fund may also invest a significant amount of its assets in short positions in equity securities and fixed income obligations, in commodities-related investments, in derivative instruments, in currencies, and in cash or cash equivalents.

There are no specific percentage limitations on the amount of the Fund’s portfolio that may be invested in a particular asset class, and the proportions of the Fund’s assets that are invested in the respective asset classes are expected to vary over time and from time to time depending upon Thornburg’s perceptions of which types of investments represent better values and opportunities to achieve the Fund’s investment goal.

Performance drivers and detractors for the reporting period ending September 30, 2020

» Selection effect within equities and fixed income contributed strongly to relative outperformance during the trailing 12-month period. The Fund’s allocation to commodities and cash was modestly detractive.

» Within equities, selection effect from consumer discretionary and communication services contributed positively to relative performance.

» The Fund’s overweight allocation and stock selection in health care names detracted from relative performance.

» Overweight exposure to the duration of U.S. and foreign treasuries contributed positively to relative performance as rates decreased.

» Underweight exposure to the duration of corporate bonds and asset-backed securities detracted from relative performance.

Thornburg International Value Fund

Investment Goal and Fund Overview

The International Value Fund seeks long-term capital appreciation by investing in equity and debt securities of all types. The secondary, non-fundamental goal of the Fund is to seek some current income.

The Fund invests in a limited number of foreign common stocks selected on a value basis using fundamental research. The portfolio is diversified to include basic value stocks, but also includes stocks of companies with consistent earnings characteristics and those of emerging franchises, when these issues are value priced.

Performance drivers and detractors for the reporting period ending September 30, 2020

» For the 12-month period ended September 30, 2020, the Fund (Class I shares) returned 15.74% compared to a return of 3.00% for the MSCI AC World ex USA Net Total Return USD Index and 0.49% for the MSCI EAFE Net Total Return USD Index.

» The 12-month period featured three quarters of strong positive returns for the Fund, the exception being the first quarter of 2020 when COVID-19 concerns caused sharp losses across global markets.

» The Fund’s strong absolute and relative performance for the 12 months was driven primarily by bottom-up security selection. The only exception was the first quarter of 2020 when outperformance was driven by sector, country and currency allocation.

» An underweight in financials, energy and real estate and an overweight in information technology and communication services helped performance. An overweight in China and Switzerland and an underweight in the U.K. and Australia were positive, while an overweight in the eurozone was negative.

» Stock selection was strong over the period, but was strongest in consumer discretionary, communication services and consumer staples and weakest in industrials. By country it was strongest in China, Japan and Switzerland and weakest in the eurozone and Australia.

» An underweight to consumer staples and materials detracted from Fund performance due to a combination of stock selection and allocation impact.

Thornburg Developing World Fund

Investment Goal and Fund Overview

The Developing World Fund’s primary investment goal is long-term capital appreciation. The Fund invests at least 80% of its assets in equity securities and debt obligations of developing country issuers. A developing country issuer is a company or sovereign entity that is domiciled or otherwise tied economically to one or more developing countries. The Fund portfolio is diversified to include basic value stocks, companies with consistent earnings, and emerging franchises.

Performance drivers and detractors for the reporting period ending September 30, 2020

» For the trailing 12-month period ending September 30, 2020, more than 90% of the Fund’s outperformance on a sector basis was attributable to stock selection, with sector allocation decisions modestly detractive and currency allocation modestly contributive.

» Stock selection within consumer staples, communication services and financials was especially additive to relative performance.

» Stock selection and allocation to industrials detracted from our relative performance, as a few travel-related names were especially pressured during the first quarter of 2020.

» On a regional basis, all of the portfolio’s outperformance was attributable to stock selection, with China- and Taiwan-domiciled holdings being especially additive to relative performance.

» Overweight allocations to Latin America detracted from the portfolio’s relative performance during the period. A U.K.-domiciled company with 100% of revenues generated in the Middle East and Africa also detracted.

Thornburg Long/Short Equity Fund

Investment Goal and Fund Overview

The Long/Short Equity Fund seeks long-term capital appreciation.

The Fund pursues its investment goal by investing a significant amount of its assets in long and short positions in a broad range of equity securities. While the Fund normally expects to invest a larger portion of its portfolio in long positions than short positions, the Fund expects to invest a significant portion of its assets in short positions.

Performance drivers and detractors for the reporting period ending September 30, 2020

» The Fund underperformed the S&P 500 Total Return Index during the 12-month period ending September 30, 2020.

» The Fund’s long market exposure was able to best the performance of the index during the period, but the Fund’s short market exposure proved no match for the deluge of liquidity unleashed to combat the effects of the COVID-19 pandemic.

» The solid performance of the long book was driven by both the sector allocation and stock performance within the communication services and consumer discretionary sectors.

» The challenging performance of the short book was driven by the allocations to the consumer discretionary and financials. The consumer discretionary sector, in particular, accounted for a large part of the Fund’s underperformance due to the large weighting and holdings within the sector. The market rally was very thematic leading investors to bid up perceived beneficiaries of the pandemic regardless of business fundamentals and valuation.

The Dividend Landscape
Thornburg Investment Income Builder Fund^|September 30, 2020 (Unaudited)

To appreciate the investment environment in which Thornburg Investment Income Builder Fund operates, you may wish to review these highlights of the “dividend landscape.”

The S&P 500 Index Payout Ratio — A Historical Perspective

The dividend payout ratio is a fraction that expresses dividend payments as a percentage of per-share earnings. As the economy slowed in the wake of the financial crisis, earnings-per-share on average declined, causing the payout ratio to spike, even as dividends paid by the S&P 500 portfolio declined. Earnings have since materially improved, bringing the payout ratio back in line with the overall trend in recent times.

Corporate Willingness to Pay Dividends is Key to the Fund’s Investment Process

The Russell 1000 Index includes approximately 1,000 public companies that are supposed to be generally representative of corporate America. Between 1980 and 1993, at least 75% of these firms paid some dividend. Between 1994 and 2001, the percentage of Russell 1000 companies paying dividends sank to just over 50%, indicating a preference towards reinvesting retained earnings in growth initiatives. Dividends returned to fashion between 2002 and 2008. A reduction in the number of Russell 1000 firms paying dividends followed the 2008 recession. However, from early 2010, the number steadily climbed back to around 70%.

Rising Dividend Payments Despite Decreasing Dividend Yields

Over time, the dollar dividend per unit of the S&P 500 Index has generally increased. Because the price of the index itself has increased even more, the yield on the S&P 500 Index, as a percentage of the current index price, has generally decreased in recent decades. You should note, however, that the dollar yield on an original investment made at a fixed point in time (say, 1970 or 1989) has increased, even without reinvestment of dividends.

Estimated Average Dividend Yields (MSCI Indices) of Markets Around the Globe

A Truly Diversified Dividend-Paying Portfolio Must Look Beyond the Obvious High-Yield Stocks!

In the (large cap) Russell 1000 Index, 57% of the top 100 dividend payers are in the real estate and financials sectors. In the (small cap) Russell 2000 Index, 66% of the top 100 dividend-yielding stocks are real estate or financials companies. To construct a diversified portfolio of attractive yielding stocks, one must look beyond these sectors. We certainly do.

Dividend yield is a ratio that shows how much a company pays out in dividends each year relative to its share price.

Global Diversification Can Improve the Portfolio Yield

Since firms outside the U.S. tend to pay higher dividends than U.S. firms, particularly outside the financial and utility sectors, we maintain the ability to diversify the Thornburg Investment Income Builder Fund into foreign dividend-paying stocks to try to take advantage of these opportunities.

Diversification does not assure or guarantee better performance and cannot eliminate the risk of investment losses.

Dividends are not guaranteed.

All countries are vulnerable economically to the impact of a public health crisis, such as the novel virus known as COVID-19. Such crises may depress consumer demand, disrupt supply chains, slow economic growth, and potentially lead to market closures, travel restrictions, government-imposed shutdowns, and quarantines, all of which could adversely affect the economies of many of the markets in which the Funds invest, and which could in turn lead to declines in the value of the Funds’ investments or decrease the liquidity of those investments.

As of September 30, 2020, the Funds currently offer from one to seven classes of shares of beneficial interest:

Each class of shares of the Funds 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 C shares are sold at net asset value without a sales charge at the time of purchase, but are subject to a contingent deferred sales charge upon redemption within one year of purchase, and bear both a service fee and a distribution fee, (iii) Class I and Class R5 shares are sold at net asset value without a sales charge at the time of purchase and may be subject to a service fee, (iv) Class R3 shares are sold at net asset value without a sales charge, but bear both a service fee and a distribution fee, (v) Class R4 shares are sold at net asset value without a sales charge at the time of purchase but bear a service fee, (vi) Class R6 shares are sold at net asset value without a sales charge at the time of purchase, and (vii) the respective classes may have different reinvestment privileges and conversion rights. Additionally, each Fund may allocate among its classes certain expenses, to the extent allocable to specific classes, including administration fees, transfer agent fees, government registration fees, certain printing and postage costs and legal expenses. Currently, class specific expenses of the Funds are limited to distribution and service fees, transfer agent fees, and certain registration and filing fees.

At September 30, 2020, the following classes of shares are offered in each respective Fund:

NOTE 2 – SIGNIFICANT ACCOUNTING POLICIES

The following is a summary of significant accounting policies followed by each of the Funds in the preparation of its financial statements. Each 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.

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 daily 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 dividends, if any, are declared daily and paid quarterly or annually. Capital gain distributions, if any, are declared and paid annually and more often if deemed necessary by the Advisor. Dividends and distributions are paid and are reinvested in additional shares of the Funds 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.

Notes to Financial Statements, Continued
September 30, 2020

Foreign Currency Translation: Portfolio investments and other assets and liabilities denominated in foreign currencies are translated into U.S. dollars based on the exchange rate of such currencies against the U.S. dollar on the date of valuation. Purchases and sales of investments and income items denominated in foreign currencies are translated into U.S. dollars at the exchange rate in effect on the transaction date. When the Funds purchase or sell foreign investments, they will customarily enter into a foreign exchange contract to minimize foreign exchange risk from the trade date to the settlement date of such transactions. The values of such spot contracts are included in receivable for investments sold and payable for investments purchased on the Statement of Assets and Liabilities.

The Funds do not separately report the effect of changes in foreign exchange rates from changes in market prices on investments held. Such changes are included in net unrealized appreciation (depreciation) from investments in the Statement of Operations.

Reported net realized gains and losses from foreign currency transactions arise due to purchases and sales of foreign currencies, currency gains and losses realized between the trade and settlement dates on investment transactions and the difference between the amounts of dividends, interest, and foreign withholding taxes recorded on the Funds’ books, and the U.S. dollar equivalent of the amounts actually received or paid. These amounts are included in foreign currency transactions in the Statement of Operations.

Net change in unrealized appreciation (depreciation) on foreign currency translations arise from changes in the fair value of assets and liabilities, other than investments at period end, resulting from changes in exchange rates.

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 Funds. 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.

Investment Income: Dividend income is recorded on the ex-dividend date. Certain income from foreign investments is recognized as soon as information is available to the Funds. Interest income is accrued as earned. Premiums and discounts are amortized and accreted, respectively, to first call dates or maturity dates using the effective yield method of the respective investments. These amounts are included in Investment Income in the Statement of Operations.

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.

Repurchase Agreements: The Funds may invest excess cash in repurchase agreements whereby the Funds purchase investments, which serve as collateral, with an agreement to resell such collateral to the seller at an agreed upon price at the maturity date of the repurchase agreement. Investments pledged as collateral for repurchase agreements are held in custody until maturity of the repurchase agreement. Provisions in the agreements require that the market value of the collateral is at least equal to the repurchase value in the event of default. In the event of default, the Funds have the right to liquidate the collateral and apply the proceeds in satisfaction of the obligation. Under certain circumstances, in the event of default or bankruptcy by the other party to the agreement, realization and/or retention of the collateral may be subject to legal proceedings.

Security Valuation: All investments in securities held by the Funds are valued as described in Note 3.

Short Sales: A short sale involves the sale by the Funds of a security that the Funds do not own. The Funds borrow the security that they intend to sell from a broker or other institution, and at a later date the Funds complete the short sale by purchasing that same security on the open market and delivering it to the lending institution. The Funds may be required to pay a premium, fee, or other amount to the lender in exchange for borrowing the security. These amounts are included in "Short sale financing fees" on the Statement of Operations. When it enters into a short sale, the Funds seek to profit on a decline in the price of the security between the date the Funds borrow the security and the date the Funds purchase the security to deliver it to the lender. If, however, the price of the security increases between those dates, or if the price of the security declines by an amount which is not sufficient to cover the expenses of borrowing the security, the Funds will experience a loss. Although the potential for gain as a result of a short sale is limited to the price at which the Funds sold the security short less the cost of borrowing the security, the potential for loss is theoretically unlimited because there is no limit to the cost of replacing the borrowed security. Short sales held by the Funds during the fiscal year were fully collateralized by segregated cash or other securities, which are denoted on the Schedule of Investments.

Unfunded Loan Commitments: The Income Builder Fund has entered into a loan commitment with Malamute Energy, Inc., of which at September 30, 2020, $318,495 of the $637,245 par commitment had been funded. The maturity date is December 31, 2020.

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.

September 30, 2020

When-Issued and Delayed Delivery Transactions: The Funds may engage in when-issued or delayed delivery transactions. To the extent the Funds engage in such transactions, they will do so for the purpose of acquiring portfolio investments consistent with the Funds’ investment objectives and not for the purpose of investment leverage or to speculate on interest rate or market changes. At the time the Funds make a commitment to purchase an investment on a when-issued or delayed delivery basis, the Funds 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 investments to be purchased will be segregated on the Funds’ records on the trade date. Investments purchased on a when-issued or delayed delivery basis do not earn interest until the settlement date. The values of these securities held at September 30, 2020 are detailed in the Schedule of Investments.

NOTE 3 – SECURITY VALUATION

Valuation of the Funds’ 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 with obtaining fair market values for portfolio investments, evaluating and monitoring professional pricing service providers appointed by the Trustees’ Audit Committee (the “Audit Committee”) to assist in determining fair values for portfolio investments, assisting in calculating fair values for portfolio investments in certain circumstances, and performing 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, reviews 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 Funds 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 Funds upon a sale of the investment, and the difference could be material to the Funds’ 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: Securities and other portfolio investments which are listed or traded on a United States securities exchange are valued at the last reported sale price on the valuation date. Investments listed or traded on an exchange for which there has been no sale that day are valued at the mean between the last reported bid and asked prices on that valuation date. Portfolio investments reported by NASDAQ are valued at the official closing price on the valuation date. If an investment is traded on more than one exchange, the investment is considered traded on the exchange that is normally the primary market for that investment. Securities and other portfolio investments which are listed or traded on exchanges outside the United States are valued at the last price or the closing price of the investment on the exchange that is normally the primary market for the investment, as of the close of the exchange preceding the Funds’ valuation date. Foreign investments listed or traded on an exchange for which there has been no sale that day are valued at the mean between the last reported bid and asked prices on that valuation date.

In any case when a market quotation is not readily available for a portfolio investment ordinarily valued by market quotation, the Committee calculates a fair value for the investment using alternative methods approved by the Audit Committee. A market quotation is not readily available when the primary market or exchange for the investment is not open for the entire scheduled day of trading. Market quotations for an investment also may not be readily available if developments after the most recent close of the investment’s primary exchange or market, but prior to the close of business on any Funds’ business day, or an unusual event or significant period of time occurring since the availability of a market quotation, create a serious question concerning the reliability of the most recent market quotation available for the investment. In particular, on days when market volatility thresholds established by the Audit Committee are exceeded, foreign equity investments held by the Funds may be valued using alternative methods. The Committee customarily obtains valuations in these instances from pricing service providers approved by the Audit Committee. Pricing service providers ordinarily calculate valuations using multi-factor models to adjust market prices based upon various inputs, including exchange data, depository receipt prices, futures, index data and other data.

Debt obligations held by the Funds 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.

Investments in open-end U.S. mutual funds are valued at net asset value (“NAV”) each business day.

In any case when a pricing service provider fails to provide a valuation for a debt obligation held by the Funds, 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 is stale, does not reflect material factors affecting the valuation of the investment, is significantly different than the value the Funds are likely to obtain if it sought a bid for the investment, or is otherwise unreliable, the Committee calculates a fair value for the obligation using an alternative method approved by the Audit Committee.

Quotations for foreign investments expressed in foreign currency amounts are converted to U.S. dollar equivalents using a foreign exchange quotation from a third party service provider at the time of valuation. Foreign investments held by the Funds may be traded on days and at times when the Funds are not open for business. Consequently, the value of Funds’ investments may be significantly affected on days when shareholders cannot purchase or sell Funds’ shares.

Valuation Hierarchy: The Funds categorize their 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 Funds’ 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 ratings, 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 Funds are typically calculated by pricing service providers approved by the Audit Committee and are generally characterized as Level 2 within the valuation hierarchy.

On days when market volatility thresholds established by the Audit Committee are exceeded, foreign securities for which valuations are obtained from pricing service providers are fair valued. On these days, the foreign securities are characterized as Level 2 within the valuation hierarchy and revert to Level 1 after the threshold is no longer exceeded.

In any case when a pricing service provider fails to provide a valuation for a debt obligation held by the Funds, 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 is stale, does not reflect material factors affecting the valuation of the investment, is significantly different than the value the Funds are likely to obtain if they sought a bid for the investment, or is otherwise unreliable, the Committee calculates a fair value for the obligation using an alternative method approved by the Audit Committee.

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 a fund may receive a price that is lower than the valuation based upon these inputs when it sells the investment.

NOTE 4 – INVESTMENT MANAGEMENT FEE AND OTHER TRANSACTIONS WITH AFFILIATES

Pursuant to an investment management agreement, the Advisor serves as the investment advisor and performs services for the Funds for which the fees are payable at the end of each month. Under the investment advisory agreement, each Fund pays the Advisor a management fee based on the average daily net assets of the Funds at an annual rate as shown in the following table:

INCOME BUILDER FUND, GLOBAL OPPORTUNITIES FUND, INTERNATIONAL VALUE FUND, INTERNATIONAL GROWTH FUND, VALUE FUND, GROWTH FUND		SUMMIT FUND		BETTER WORLD INTERNATIONAL FUND, DEVELOPING WORLD FUND		LONG/SHORT EQUITY FUND

The Trust has entered into an administrative services agreement with the Advisor, whereby the Advisor will perform certain administrative services related to each class of the Funds’ shares. 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:

Administrative Services Fee Schedule
Daily Net Assets	Fee Rate
Up to $20 billion	0.100%
$20 billion to $40 billion	0.075
$40 billion to $60 billion	0.040
Over $60 billion	0.030

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 Funds. Total administrative services fees incurred by each class of shares of the Funds for the year ended September 30, 2020, 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 Funds’ shares. For the year ended September 30, 2020, the Distributor has advised the Funds that they earned net commissions from the sale of Class A shares and collected contingent deferred sales charges ("CDSC Fees") from redemptions of Class C shares as follows:

	Commissions	CDSC fees
Income Builder Fund	$ 225,461	$ 93,057
Global Opportunities Fund	7,383	4,678
International Value Fund	7,339	3,405

Developing World Fund	5,447	1,832
Value Fund	10,301	1,263
Growth Fund	11,492	1,959

Pursuant to a service plan under Rule 12b-1 of the 1940 Act, the Funds may reimburse to the Distributor an amount not to exceed .25 of 1% per annum of the average daily net assets attributable to the applicable Class A, Class C, Class I, Class R3, Class R4, and Class R5 shares of the Income Builder Fund, Global Opportunities Fund, International Value Fund, International Growth Fund, Value Fund and Growth Fund, Class A, Class C, Class I, and Class R5 shares of the Developing World Fund, Class A, Class C, Class I shares of the Better World International Fund and Class I shares of the Summit Fund and Long/Short Equity Fund. For the year ended September 30, 2020,

Notes to Financial Statements, Continued
September 30, 2020

there were no 12b-1 service plan fees charged for Class I or Class R5 shares. Class R6 shares are not subject to a service plan. The Advisor and Distributor each may pay out of its own resources additional expenses for distribution of each Funds’ shares and shareholder services.

The Trust has also adopted a distribution plan pursuant to Rule 12b-1, applicable only to the Funds’ Class C and Class R3 shares, under which the Funds compensate the Distributor for services in promoting the sale of Class C and Class R3 shares of the Funds at an annual rate of up to .75 of 1% per annum of the average daily net assets attributable to Class C shares, and an annual rate of up to .25 of 1% per annum of the average daily net assets attributable to Class R3 shares. Total fees incurred by each class of shares of the Funds under their respective service and distribution plans for the year ended September 30, 2020 are set forth in the Statements of Operations.

The Advisor has contractually agreed to waive fees and reimburse expenses incurred by the Funds. The agreement may be terminated by the Funds at any time, but may not be terminated by the Advisor before February 1, 2021 as to the Income Builder Fund, Summit Fund, Global Opportunities Fund, International Value Fund, Better World International Fund, International Growth, and Developing World Fund, and may not be terminated by the Advisor before September 30, 2021 as to the Value Fund and Growth Fund, unless the Advisor ceases to be the investment advisor to the Funds prior to such dates. The Advisor may recoup amounts waived or reimbursed during the year ended September 30, 2020 if, during the fiscal year, expenses fall below the contractual limit that was in place at the time these fees and expenses were waived or reimbursed. The Advisor will not recoup fees or expenses as described in the preceding sentence if that recoupment would cause the Fund’s total annual operating expenses (after the recoupment is taken into account) to exceed the lesser of: (a) the expense cap that was in place at the time the waiver or reimbursement occurred; or (b) the expense cap that is in place at the time of the recoupment.

Actual expenses of certain share classes do not exceed levels as specified in each Fund’s most recent prospectus as shown in the following table:

	Class A	Class C	Class I	Class R3	Class R4	Class R5	Class R6
Income Builder Fund	—%	—%	—%	1.50%	1.40%	0.99%	0.80%

NOTE 5 – TAXES

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 Funds. Therefore, no provision for federal income or excise tax is required.

The Funds file income tax returns in United States federal and applicable state jurisdictions. The statute of limitations on the Funds’ tax return filings generally remains open for the three years following a return’s filing date. The Funds have analyzed each uncertain tax position believed to be material in the preparation of the Funds’ financial statements for the fiscal year ended September 30, 2020, 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 Funds have not identified any such position for which an asset or liability must be reflected in the Statements of Assets and Liabilities.

At September 30, 2020, information on the tax components of capital were as follows:

	Cost	Unrealized Appreciation	Unrealized Depreciation	Net Unrealized Appreciation (Depreciation)
Income Builder Fund	$ 8,840,828,232	$ 2,043,065,839	$ (1,351,025,936)	$ 692,039,903

Long/Short Equity Fund	11,093,450	23,793,461	(4,690,231)	19,103,230

Temporary differences between book and tax basis appreciation (depreciation) on cost of investments is primarily attributed to tax deferral of losses on wash sales, distributions from real estate investment trusts (“REITs”), distributions from non-REIT securities, partnership basis adjustments and mark-to-market of forward currency contracts.

102 | Thornburg Equity Funds Annual Report

Notes to Financial Statements, Continued
September 30, 2020

At September 30, 2020, the Funds had deferred tax basis late-year ordinary investment losses and deferred tax basis capital losses occurring subsequent to October 31, 2019 through September 30, 2020 per the following table. For tax purposes, such losses will be recognized in the year ending September 30, 2021.

	Deferred Tax Basis
	Late-Year Ordinary Losses	Capital Losses
Income Builder Fund	$ —	$ 642,612,020
Value Fund	—	4,051,938
Long/Short Equity Fund	1,547,334	22,158,746

At September 30, 2020, the Funds had cumulative tax basis capital losses from prior fiscal years as shown on the following table, 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.

	Cumulative Capital Losses
	Short-Term	Long-Term
Income Builder Fund	$ 565,486,574	$ 5,698,378
Better World International Fund	488,669	—
Developing World Fund	153,467,637	—
Long/Short Equity Fund	1,600,832	—

During the year ended September 30, 2020, the Funds utilized capital loss carryforwards as shown on the following table.

	Utilized Capital Loss Carryforwards
Value Fund	$ 4,653,285

At September 30, 2020, the effect of permanent "book/tax" reclassifications resulted in increases and decreases to components of the Funds’ net assets as follows:

	Distributable Earnings	Net Capital Paid
Summit Fund	$ 33	$ (33)
Global Opportunities Fund	(14,187,197)	14,187,197
International Value Fund	(9,815,598)	9,815,598
International Growth Fund	(57,344)	57,344
Value Fund	5,294	(5,294)
Long/Short Equity Fund	4,223,540	(4,223,540)

These differences are primarily due to the tax treatment of partnership basis adjustments, equalization credits and net operating losses.

Foreign Withholding Taxes: The Funds are subject to foreign tax withholding imposed by certain foreign countries in which the Funds may invest. Withholding taxes are incurred on certain foreign dividends and are accrued at the time the dividend is recognized based on applicable foreign tax laws. The Funds may file withholding tax reclaims in certain jurisdictions to recover a portion of amounts previously withheld, in view of various considerations, including recent decisions rendered by the courts in those and other jurisdictions. The Funds would expect to record a receivable for such a reclaim based on a variety of factors, including assessment of a jurisdiction’s legal obligation to pay reclaims, the jurisdiction’s administrative practices and payment history, and industry convention. To date the Funds have recorded no such receivable because there is limited precedent for collecting such prior year reclaims.

Deferred Foreign Capital Gain Taxes: The Funds are subject to a tax imposed on net realized gains of securities of certain foreign countries. The Funds record an estimated deferred tax liability for net unrealized gains on these investments as reflected in the accompanying financial statements. Such changes are included in net unrealized appreciation (depreciation) from investments in the Statement of Operations.

NOTE 8 – DERIVATIVE FINANCIAL INSTRUMENTS WITH OFF-BALANCE
SHEET RISK AND FOREIGN INVESTMENT RISK

The Funds may use a variety of derivative financial instruments to hedge or adjust the risks affecting its investment portfolio or to enhance investment returns. Provisions of the FASB Accounting Standards Codification 815-10-50 (“ASC 815”) require certain disclosures. The disclosures are intended to provide users of financial statements with an understanding of the use of derivative instruments by the Funds and how these derivatives affect the financial position, financial performance and cash flows of the Funds. The Funds do not designate any derivative instruments as hedging instruments under ASC 815. During the year ended September 30, 2020, the Funds’ principal exposure to derivative financial instruments of the type addressed by ASC 815 was investment in foreign currency contracts. A foreign currency contract is an agreement between two parties to exchange different currencies at a specified rate of exchange at an agreed upon future date. Foreign currency contracts involve risks to the Funds, including the risk that a contract’s counterparty will not meet its obligations to the Funds, the risk that a change in a contract’s value may not correlate perfectly with the currency the contract was intended to track, and the risk that the Funds’ Advisor is unable to correctly implement its strategy in using a contract. In any such instance, the Funds may not achieve the intended benefit of entering into a contract, and may experience a loss.

The Funds entered into forward currency contracts during the year ended September 30, 2020 in the normal course of pursuing its investment objectives, with the objective of purchasing foreign investments or with the intent of reducing the risk to the value of the Funds’ foreign investments from adverse changes in the relationship between the U.S. dollar and foreign currencies. In each case these contracts have been initiated in conjunction with foreign investment transactions.

The monthly average values of open forward currency sell contracts for the year ended September 30, 2020 for Income Builder Fund, Summit Fund, Global Opportunities Fund, International Value Fund, International Growth Fund and Value Fund were $2,139,073,574; $283,129; $116,792,854; $161,235,371; $7,073,735 and $24,673,246, respectively.

These contracts are accounted for by the Funds under ASC 815. Unrealized appreciation and depreciation on outstanding contracts are reported in each Fund’s Statement of Assets and Liabilities, as measured by the difference between the forward exchange rates at the reporting date and the forward exchange rates at each contract’s inception date. Net realized gain (loss) on contracts closed during the period, and changes in net unrealized appreciation (depreciation) on outstanding contracts are recognized in each Fund’s Statement of Operations.

These outstanding forward currency contracts in the table located in the Schedule of Investments which were entered into with State Street Bank and Trust Company (“SSB”) and with Morgan Stanley & Co. Inc. ("MSC") were entered into pursuant to International Swaps and Derivatives Association (“ISDA”) Master Agreements. In the event of a default or termination under the ISDA Master Agreement with SSB or MSC, the non-defaulting party has the right to close out all outstanding forward currency contracts between the parties and to net any payment amounts under those contracts, resulting in a single net amount payable by one party to the other.

Because the ISDA Master Agreement with SSB and the ISDA Master Agreement with MSC do not result in an offset of reported amounts of financial assets and liabilities in the Funds’ Statement of Assets and Liabilities unless there has been an event of default or termination event under such agreements, the Funds do not net its outstanding forward currency contracts for the purpose of disclosure in the Funds’ Statement of Assets and Liabilities. Instead the Funds recognize the unrealized appreciation (depreciation) on those forward currency contracts on a gross basis in the Funds’ Statement of Assets and Liabilities.

The unrealized appreciation (depreciation) of the outstanding forward currency contracts recognized in each Fund’s Statement of Assets and Liabilities at September 30, 2020 is disclosed in the following table:

	Type of Derivative^(a)	Counter Party	Asset Derivatives	Liability Derivatives	Net Amount

Value Fund	Foreign currency contracts	SSB	266,046	—	266,046

(a)	Generally, the Statement of Assets and Liabilities location for forward currency contracts is Assets - Unrealized appreciation on forward currency contracts for asset derivatives and Liabilities - Unrealized depreciation on forward currency contracts for liabilities derivatives.

Because the Funds did not receive or post cash collateral in connection with its currency forward contracts during the period, the net amounts of each Fund’s assets and liabilities which are attributable to those contracts at September 30, 2020 can be determined by offsetting the dollar amounts shown in the asset and liability columns in the preceding table, the results of which are reflected in the "Net Amount" column. The Funds’ forward currency contracts are valued each day, and the net amounts of each Fund’s assets and liabilities which are attributable to those contracts are expected to vary over time.

The net realized gain (loss) from forward currency contracts and the net change in unrealized appreciation (depreciation) on outstanding forward currency contracts recognized in the Fund’s Statement of Operations for the year ended September 30, 2020 are disclosed in the following table:

		Net Realized	Net Change in Unrealized

Basis for Opinions

These financial statements are the responsibility of the Funds’ management. Our responsibility is to express an opinion on the Funds’ 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 Funds 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 of these financial statements 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.

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. Our procedures included confirmation of securities owned as of September 30, 2020 by correspondence with the custodians, agent banks, transfer agent, and brokers; when replies were not received from brokers, we performed other auditing procedures. We believe that our audits provide a reasonable basis for our opinions.

Expense Example
September 30, 2020 (Unaudited)

As a shareholder of the Fund, you incur two types of costs:

(1)	transaction costs, including

(a)	sales charges (loads) on purchase payments, for Class A shares;
(b)	a deferred sales charge on redemptions of any part or all of a purchase of $1 million of Class A shares within 12 months of purchase;
(c)	a deferred sales charge on redemptions of Class C shares within 12 months of purchase;

(2)	ongoing costs, including management fees; distribution and/or service (12b-1) fees; and other Fund expenses.

This example is intended to help you understand your ongoing costs (in dollars) of investing in the Fund and to compare these costs with the ongoing costs of investing in other mutual funds.

The example is based on a $1,000 investment beginning on April 1, 2020, and held until September 30, 2020.

ACTUAL EXPENSES

For each class of shares, the first line of the accompanying table provides information about actual account values and actual expenses. You may use the information in this line, together with the amount you invested, to estimate the expenses that you paid over the period. Simply divide your account value by $1,000 (for example, an $8,600 account value divided by $1,000 = 8.6), then multiply the result by the number in the first line for your class of shares under the heading entitled “Expenses Paid During Period” to estimate the expenses you paid on your account during this period.

HYPOTHETICAL EXAMPLE FOR COMPARISON PURPOSES

For each class of shares, the second line of the accompanying table provides information about hypothetical account values and hypothetical expenses based on the Fund’s actual expense ratio and an assumed rate of return of 5% per year before expenses, which is not the Fund’s actual return. The hypothetical account values and expenses may not be used to estimate the actual ending account balance or expenses you paid for the period. You may use this information to compare the ongoing costs of investing in the Fund and other funds. To do so, compare this 5% hypothetical example with the 5% hypothetical examples that appear in the shareholder reports of the other funds.

Please note that the expenses shown in the table are meant to highlight your ongoing costs only and do not reflect any transactional costs, such as sales charges (loads), redemption fees, or exchange fees. Therefore, the second line of the table for each class of shares is useful in comparing ongoing costs only, and will not help you determine the relative total costs of owning different funds. In addition, if these transactional costs were included, your costs would have been higher.

STATEMENT RESPECTING RENEWAL OF INVESTMENT ADVISORY AGREEMENT

Thornburg Investment Management, Inc. (the “Advisor”) provides investment management services to each of the Funds pursuant to an investment advisory agreement (the “Agreement”). The Board of Trustees (the “Trustees”) consider the renewal of the Agreement annually, and most recently determined to renew the Agreement on September 15, 2020.

Planning for their recent consideration of the Agreement’s renewal, those Trustees who are not “interested persons” of the Trust, as defined in Section 2(a)(19) of the Investment Company Act of 1940, as amended (the “independent Trustees”), met in May 2020 to consider aspects of their annual evaluation of the Advisor’s service to the Funds and to each other series of the Trust, to plan the annual evaluation of the Advisor’s performance, and to discuss preliminarily the information the Advisor would present to the Trustees for their review. The independent Trustees met in a second independent session in July 2020 to further define certain portions of the information to be submitted by the Advisor. The independent Trustees met again in independent session in September 2020 with representatives of a mutual fund analyst firm engaged by the independent Trustees to provide explanations of comparative cost and expense information, comparative investment performance information, and other data obtained and analyzed by the analyst firm. In that session the independent Trustees discussed their evaluations of the Advisor’s services to the Funds and the Funds’ fee and expense levels, investment performance, and other information presented for the Funds, conferred independently with legal counsel respecting the factors typically considered in evaluating renewal of an advisory agreement, and conferred with representatives of management to receive explanations of certain aspects of the information they had requested. Representatives of the Advisor subsequently reviewed portions of the information with the Trustees and addressed questions from the Trustees at a full meeting session of the Trustees scheduled in September for that purpose, and the independent Trustees thereafter met again in independent session to consider the Advisor’s presentations and various specific issues respecting their consideration of the Agreement’s renewal. Following these sessions, the Trustees met to consider renewal of the Agreement, and the independent Trustees voted unanimously at that meeting to renew the Agreement for an additional term of one year.

The information below summarizes certain factors considered by the Trustees in connection with the determination to renew the Agreement. In determining to renew the Agreement, the Trustees considered a wide range of information and did not identify any single factor as controlling, and this summary does not describe all of the factors and other matters considered by the Trustees in making their determination.

Nature, Extent, and Quality of Services. The Trustees considered in their evaluation of the Agreement the written and oral reports provided to the Trustees and their standing committees throughout the year on a wide variety of topics by personnel from the Advisor’s portfolio management, administration, operations, and compliance staffs. The Trustees also considered in this evaluation presentations and explanations made by representatives of the Advisor in meeting sessions scheduled for consideration of the renewal of the Agreement. The Trustees further noted in their evaluation the consideration they had given to a number of topics in previous years, reports from their standing committees, and advice received from counsel.

Information noted by the Trustees as having been considered in relation to the nature, extent, and quality of services provided by the Advisor under the Agreement and contributing (together with other information considered) to their conclusions respecting the nature, extent, and quality of the services rendered to the Funds by the Advisor included: (1) reports from portfolio managers throughout the year demonstrating that the Funds were managed in conformity with stated strategies and objectives and conformed to investment restrictions and limitations; (2) reports demonstrating that management of the Funds remained faithful and competent, and demonstrating sufficient skill by portfolio managers in executing the Funds’ strategies in varying environments, managers’ cognizance of and strategies to pursue the Funds’ objectives and address pertinent market and economic trends and conditions, the evaluation and selection of individual investments, management to achieve tax efficiencies, and the structuring and composition of the Funds’ portfolios and management of the Funds’ liquidity requirements; (3) each Fund’s achievement of its investment objectives over different periods of time; (4) presentations by and interactions with members of the Advisor’s fund administration, trading, operations, and compliance staffs; (5) reports from standing committees of the Trustees on their respective proceedings throughout the year, including particularly interactions with the Advisor’s personnel; (6) the sufficiency of the resources the Advisor devotes to the services it provides to the Funds, including the expertise of its personnel and staffing levels and its enhancements to the electronic systems it utilizes in providing these services, and the Advisor’s own financial management and sufficiency of its resources; (7) steps taken by the Advisor to improve its investment management process, including the appointment of two new Co-Heads of Investment, the restructuring of the equity analyst team, the hiring of new analysts to support the investment management function, and the increased integration of new risk management procedures and consideration of

environmental, social, and governance factors into the investment process; (8) the measures employed to achieve efficient trade execution for the Funds, including the evaluation and selection of firms to execute transactions for the Funds; and (9) steps taken by the Advisor to respond to challenges presented by the ongoing COVID-19 pandemic, including steps taken to facilitate continued collaboration among the Advisor’s personnel notwithstanding the fact that most personnel are working remotely. As in past years, the Trustees noted particularly their assessments of the Advisor’s personnel developed in formal and informal meetings throughout the year, measures to expand and improve the depth and experience of the Advisor’s staff, and the Advisor’s collaborative approach to investment management, continued commitment to observance of compliance and regulatory requirements in managing investments by the Funds, responsiveness to the Trustees, and other factors and circumstances.

Based upon these and other considerations, the Trustees concluded that the Advisor’s management of the Funds’ investments continued to conform to the Funds’ stated objectives and policies, and that the nature, extent, and quality of the services provided to the Funds by the Advisor remained sufficient.

Investment Performance. The Trustees noted in their evaluation of each Fund’s investment performance the written and oral reports and investment and market analyses they had received from the Advisor’s portfolio management personnel throughout the year. The Trustees also noted their consideration of information provided to them at their request in anticipation of their annual evaluation of the Advisor’s services, including the following items of information respecting the investment performance of each Fund: (1) the Fund’s absolute investment performance and achievement of stated objectives; (2) the Advisor’s explanations and written and oral commentary on the Fund’s performance in the context of the Fund’s objectives and reasonable expectations, and business, market, and economic conditions; (3) performance data for the ten most recent calendar years (or lesser number of years for each Fund having fewer calendar years of operations), comparing the Fund’s annual investment returns to a category of funds selected by an independent mutual fund analyst firm, to one or more broad-based securities indices, and to the applicable Morningstar category of funds; (4) the Fund’s investment performance for the three-month, year-to-date, one-year, since inception and, if applicable, three-, five-, and ten-year periods ending with the second quarter of the current year, comparing the Fund’s annualized returns to mutual fund categories selected by independent mutual fund analyst firms, to one or more broad-based securities indices, and to the applicable Morningstar category of funds, and assigning a percentage rank to the Fund’s performance for each period relative to each of the fund categories; (5) analyses of specified risk and performance metrics for the Fund relative to its benchmark and to a selected peer group of funds, prepared by an independent financial analyst firm engaged by the independent Trustees; (6) the Fund’s cash flows; (7) the analysis and observations of an independent mutual fund analyst firm respecting the Fund’s investment performance relative to a category of funds selected by that firm; (8) comparison of the Fund’s annualized return to the Fund’s benchmark index or indices over various periods since the Fund’s inception; and (9) various risk and return statistics. The Trustees noted their understanding that strategies pursued for a Fund may produce intermittent lower relative performance, that such Funds have in the past returned to favor as conditions changed or the strategies of those Funds gained traction, and the Advisor has in general been successful in remediating lower relative performance of Funds in cases where execution of investment strategies had contributed to lower performance. The Trustees also noted in their evaluations that to the extent pertinent they attach additional significance to the performance of each Fund from the perspective of longer-term shareholders.

Further detail considered by the Trustees with respect to the investment performance of each Fund is set forth below:

•	Thornburg Investment Income Builder Fund – the Trustees considered that the Fund underperformed its benchmark index and Morningstar category for the year-to-date, one-, three-, five-, and ten-year periods, and ranked in the third or fourth quartile of a selected peer group of funds for all such periods except the ten-year period. The Trustees noted, however, explanations from the Advisor respecting the effects of market and economic conditions on the Fund’s investment performance during relevant periods, including the market’s current disfavoring of income-producing stocks. The Trustees observed that, despite those market conditions, the Advisor’s stock selection has generally been a positive contributor to performance when compared to other peer funds, that the Advisor has continued to successfully generate current income for the Fund’s shareholders, and that the Fund has outperformed its benchmark index since its inception and has compared more favorably to peer funds over longer periods. The Trustees also considered steps the Advisor has taken to seek to improve the Fund’s investment performance.
•	Thornburg Summit Fund – the Trustees considered that the Fund outperformed its benchmark index and Morningstar category for all periods since the Fund’s inception, and ranked in the first quartile of a selected peer group of funds for the year-to-date and one-year periods. The Trustees also considered the Advisor’s success in achieving its investment objective of growing real wealth over time.
•	Thornburg Global Opportunities Fund – the Trustees considered that, while the Fund underperformed its benchmark index and Morningstar category for the year-to-date, three-, and five-year periods, the Fund outperformed its benchmark index and Morningstar category for the three months ended June 30, 2020 and for the one- and ten-year periods, and has outperformed its benchmark index since the Fund’s inception. The Trustees also considered that, while the Fund ranked in the third or fourth quartile of a selected peer group of funds for the year-to-date, three- and five-year periods, the Fund’s performance compared more favorably to that peer group for the one- and ten-year periods.
•	Thornburg International Value Fund – the Trustees considered that the Fund outperformed its benchmark index and another broad-based securities market index for the year-to-date, one-, three-, and five-year periods, and since the Fund’s inception, performed generally in line

Thornburg Equity Funds Annual Report | 139

September 30, 2020 (Unaudited)

with such indices over the ten-year period, and outperformed its Morningstar category over all such periods. The Trustees also considered that the Fund ranked in the first or second quartile of a selected peer group of funds for the year-to-date, one-, three, five, and ten-year periods.

•	Thornburg Better World International Fund – the Trustees considered that the Fund outperformed its benchmark index and Morningstar category for all periods since the Fund’s inception, and ranked in the first quartile of a selected peer group of funds for the year-to-date, one-, and three-year periods.
•	Thornburg International Growth Fund – the Trustees considered that the Fund outperformed its benchmark index and Morningstar category for the year-to-date, one-, three-, five- and ten-year periods, has also outperformed its benchmark index since the Fund’s inception, and ranked in the first or second quartile of a selected peer group of funds for the year-to-date, one-, three-, five, and ten-year periods.
•	Thornburg Developing World Fund – the Trustees considered that the Fund outperformed its benchmark index and Morningstar category for the year-to-date, one-, three-, five- and ten-year periods, has also outperformed its benchmark index since the Fund’s inception, and ranked in the first or second quartile of a selected peer group of funds for the year-to-date, one-, three-, five, and ten-year periods.
•	Thornburg Value Fund – the Trustees considered that the Fund underperformed its benchmark index and Morningstar category for the year-to-date, one-, three-, five-, and ten-year periods, and ranked in the fourth quartile of a selected peer group of funds for all such periods. The Trustees noted, however, the explanations from the Advisor respecting the effects of market and economic conditions on the Fund’s investment performance during relevant periods, and that in response to those conditions, the Advisor had proposed, and the Trustees had approved, changes to the Fund’s principal investment strategies which are expected to take effect in late 2020. The Trustees considered data from the Advisor showing the Advisor’s success in selecting the types of securities that will be part of the Fund’s forthcoming new investment mandate, and noted that the Fund’s investment performance over the year-to-date, one-, three-, five-, and ten-year periods would have compared more favorably to a peer group that reflects the new strategies that the Fund will pursue, and to the Fund’s forthcoming new benchmark index.
•	Thornburg Core Growth Fund – the Trustees considered that the Fund underperformed its benchmark index for the one-, three-, five-, and ten-year periods, underperformed its Morningstar category for the five- and ten-year periods, and ranked in the third or fourth quartile of a selected peer group of funds for the three-, five, and ten-year periods, while comparing more favorably to those comparatives over certain other periods. The Trustees noted the explanations from the Advisor respecting the effects of market and economic conditions on the Fund’s investment performance during relevant periods, and that in response to those conditions, the Advisor had proposed, and the Trustees had approved, changes to the Fund’s principal investment strategies which are expected to take effect in late 2020. The Trustees considered data from the Advisor showing the Advisor’s success in selecting the types of securities that will be part of the Fund’s forthcoming new investment mandate, and noted that the Fund’s investment performance over the year-to-date, one-, three-, five-, and ten-year periods would have compared more favorably to a peer group that reflects the new strategies that the Fund will pursue, and to the Fund’s forthcoming new benchmark index.
•	Thornburg Long/Short Equity Fund – the Trustees considered that the Fund and its predecessor fund underperformed its benchmark index and Morningstar category for the year-to-date, one-, three-, five-, and ten-year periods, and ranked in the third or fourth quartile of a selected peer group of funds for the year-to-date, one- and three-year periods. The Trustees noted, however, the explanations from the Advisor respecting the reasons for the underperformance in those periods, observing that the Advisor’s selection of short investments for the Fund had, until recently, been a positive contributor to the Fund’s investment performance, and that the Advisor has demonstrated the ability to generate outperformance in both long and short positions across different market conditions. The Trustees also considered steps the Advisor has taken to seek to improve the Fund’s investment performance, including the implementation of additional risk management procedures.

Based upon their consideration of this and other information, the Trustees concluded that the Funds’ absolute and relative investment performance over a range of pertinent holding periods on the whole was satisfactory in view of the Funds’ objectives and strategies.

Comparisons of Fee and Expense Levels. Information noted by the Trustees as having been considered in this context included a variety of comparative data respecting the Funds’ fee and expense levels. This information included comparisons of each Fund’s advisory fee and overall Fund expenses to median and average fees and expenses charged to funds in the applicable Morningstar category, comparisons of the advisory fee and total expenses for one or more Fund share classes to the fee levels and expenses of fund peer groups selected from the category by an independent mutual fund analyst firm engaged by the independent Trustees, the perspectives and advice from that mutual fund analyst firm respecting comparisons of fund fee levels and expenses to fund peer groups, and other information. In evaluating comparative fee and expense data, the Trustees considered whether the advisory fees charged to each Fund were at least generally comparable to the comparatives presented, and whether those advisory fees and overall Fund expense levels were within the range of figures established for the selected peer groups.

Further detail considered by the Trustees with respect to the comparison of the fee and expense levels of each Fund is set forth below:

September 30, 2020 (Unaudited)

•	Thornburg Investment Income Builder Fund – Comparative fee and expense data considered by the Trustees showed that the level of total expense for one share class of the Fund was comparable to both the median and average levels charged to funds in the applicable Morningstar category, that the level of total expense for a second share class was lower than the median and average levels for that category, and that the level of total expense for a third share class was higher than the median and average levels for that category. Peer group data showed that the Fund’s stated advisory fee was lower than the median level for the three peer groups, and that the total expense levels of three representative share classes were higher than the medians of their respective peer groups but comparable to other funds in the peer groups.
•	Thornburg Summit Fund – Comparative fee and expense data considered by the Trustees showed that, after fee waivers and expense reimbursements, the level of total expense for the Fund’s one share class was higher than the median and lower than the average levels charged to funds in the applicable Morningstar category. Peer group data showed that the Fund’s stated advisory fee was lower than the median level for the peer group, and that the Fund’s total expense level was higher than the median level for the peer group after waivers of fees and reimbursement of expenses, but comparable to other funds in the peer groups.

Thornburg Core Growth Fund – In considering the fees and expenses of the Fund, the Trustees considered the application of the fee waivers and expense reimbursements that are scheduled to take effect at the end of the Fund’s 2020 fiscal year, and compared the Fund’s fees and expenses to a Morningstar category and peer groups of funds that reflect the forthcoming changes in the Fund’s principal investment strategies. Comparative fee and expense data considered by the Trustees showed that, after application of those fee waivers and expense reimbursements, the level of total expense for one share class of the Fund was higher than the median and average levels charged to funds in the Morningstar category, and that the level of total expense for a second share class was lower than the median and average levels for that category. Peer group data showed that the Fund’s stated advisory fee was higher than the medians of the two peer groups considered but comparable to other funds in the peer groups, and that the total expense levels of two representative share classes were lower than the medians of their respective peer groups after waivers of fees and reimbursement of expenses.

•

Thornburg Long/Short Equity Fund – Comparative fee and expense data considered by the Trustees showed that the level of total expense for the Fund’s one share class was lower than the median and lower than the average levels charged to funds in the applicable Morningstar category. Peer group data showed that the Fund’s stated advisory fee was lower than the median level for the peer group, and that the Fund’s total expense level was also lower than the median level for the peer group.

The Trustees did not find any of the differences between the Funds’ fee and expense data and the comparable fee and expense data significant in view of their findings and conclusions respecting the other factors considered, including the quality of services provided by the Advisor to each Fund.

The Trustees also noted their consideration of information respecting the advisory fees charged by the Advisor to other investment management clients, including sub-advised mutual funds and other institutional clients, together with information about fees charged by other advisors to different clients, analysis of the differences between the requirements of institutional clients and mutual funds, analysis of the differences between the requirements of a sub-advised mutual fund and a fund as to which the investment advisor is the primary advisor and sponsor, the differences between the mutual funds as to which the Advisor is a sub-advisor and the Funds, and the consequently different investment management services provided to the different categories of clients and the differing contexts in which these arrangements are entered into. The Trustees confirmed their previous observations that the differences between the fees charged by the Advisor to different types of clients did not appear exceptional, and that the fee rates charged by the Advisor or by other investment advisors to different types of clients had limited relevance to the evaluation of the fee rate charged to mutual funds as to which the Advisor or such other advisors are the primary advisor and sponsor.

Costs and Profitability of Advisor. In reviewing the profitability of the Advisor’s services to the Funds, the Trustees considered an analysis of the Advisor’s costs and the estimated profitability to the Advisor of its services, together with data respecting the profitability of a selection of other investment management firms. The Trustees considered information from the Advisor respecting investment of its profits to maintain staffing levels, and noted that the Advisor’s profits are an important element in the compensation of employees who work for the benefit of the Funds and their shareholders. The Trustees considered information from the Advisor respecting the use of profits to enhance staff competencies through training and other measures, hire personnel to expand and develop the scope of senior management expertise, pay competitive levels of compensation, and add to the Advisor’s electronic and information technology systems to maintain or improve service levels. The Trustees noted in particular that the Advisor was able to expand staffing levels despite the ongoing COVID-19 pandemic and the additional economic uncertainty precipitated by that pandemic. The Trustees also considered the contribution of the Advisor’s cost management to its profitability, and the relationship of the Advisor’s financial resources and profitability in previous years to its ability to attract necessary personnel, invest in systems and other assets required for its service to the Funds, and maintain or improve service levels for the Funds notwithstanding fluctuations in revenues and profitability. The information considered did not indicate to the Trustees that the Advisor’s profitability was excessive.

Potential Economies of Scale. In reviewing the extent to which economies of scale would be realized by each Fund as it grows and whether fee levels reflect potential economies of scale, the Trustees considered the breakpoint structure for advisory fees chargeable to each Fund, comparisons of the fee breakpoint structure for each Fund with breakpoint structures (or the absence of such structures) for other funds in one or more peer groups selected by an independent mutual fund analyst firm, the effects of the breakpoint structure and other expense factors realized by certain funds of the Trust as their asset levels had increased, the Advisor’s undertakings to waive or reimburse certain fees and expenses for certain Funds and share classes, and the Advisor’s expenditures from its own profits and resources to maintain staffing levels, pay competitive levels of compensation, and add to its electronic and information technology systems to maintain or improve service levels. The information provided demonstrated to the Trustees that the Funds’ advisory fee breakpoint structures are reasonable in relation to the structures observed in the other funds in their respective peer groups, and that shareholders may be expected to benefit from any economies of scale, due to the advisory agreement’s breakpoint fee structure for each Fund and other factors.

and the Advisor of the Advisor’s expansion of its staffing, compliance, and systems capabilities and other resources to serve a broader variety of investment management clients. No unusual or unfair benefits to the Advisor from its relationship to the Funds were identified by the Trustees.

Summary of Conclusions. The Trustees concluded that the general nature, extent, and quality of the Advisor’s services performed under the Agreement remained sufficient, the Advisor had continued to actively and competently pursue the Funds’ stated investment objectives and adhere to the Funds’ investment policies, and that the absolute and relative investment performance of the Funds over pertinent holding periods on the whole was satisfactory in the context of the Funds’ objectives and strategies. The Trustees further concluded that the level of the advisory fee charged to each Fund by the Advisor is fair and reasonable in relation to the services provided by the Advisor, in view of the nature, extent, and quality of those services, the investment performance of each such Fund after fees and expenses, the clear disclosure of fees and expenses in the Funds’ prospectuses, comparisons of fees and expenses charged to each Fund to fees and expenses charged to other mutual funds, and the other factors and relevant circumstances considered. The Trustees accordingly determined to renew the Agreement for an additional term of one year for each of the Funds.

Trustees’ Statement to Shareholders (Unaudited)

Revised and Readopted September 15, 2020

The Trustees believe current and prospective shareholders should know how we discharge our responsibilities in supervising the Funds’ investment advisor and in reviewing the advisor’s contract for renewal. Since 2005, we have issued a statement which sets out clearly the three principal guidelines that we follow in supervising the Trust’s investment advisor on your behalf. In accordance with our customary practice, in September of this year we again reviewed our statement and concluded we should reissue this statement outlining the principal features of our supervision of the advisor’s performance of investment management services for the Funds.

We begin with the premise that each shareholder selected his or her Fund because its investments are managed by the investment advisor identified in the prospectus and in accordance with the objective and policies described in the prospectus. We realize, as each of you do, that if you believe that your Fund’s stated objective and policies no longer serve your personal investment goals, you can sell your shares and leave the Fund.

Therefore, we believe that our primary supervisory task – our principal obligation to you – is to assess the nature and quality of the advisor’s services, and to confirm that the advisor actively and competently pursues the Fund’s objective, in accordance with the policies set out in the prospectus. To do this, we meet regularly with management to review your Fund’s portfolio and to discuss the advisor’s specific actions and judgments in pursuing the Fund’s objective. We do not substitute our own judgment for the advisor’s decisions in selecting investments; the advisor is paid to exercise its informed judgment on investment decisions, and we seek to confirm, in reviewing the advisor’s performance, that the advisor is doing just that.

Second, we are conscious of costs and the effect that costs have on shareholders’ returns. We try to make sure that your Fund’s fees and costs are reasonable in relationship to the services rendered and that they are generally in line with those charged by other expert investment advisors, consistent with our belief that the Fund’s investors searched for and expect that expertise and attention and have decided to pay a reasonable price for it. We do not put the management contract “out to bid” as a matter of course, and we would not do so unless we had concluded that the advisor materially had failed to pursue the Fund’s objectives in accordance with its policies, or for other equally important reasons. We believe that any other approach would be inconsistent with your interests and contrary to your expectations when you bought shares of the Fund in the first place.

Finally, because we believe that most Thornburg Fund shareholders have invested with a long-term perspective, we try not to focus too much on the fashions of the moment and on short-term performance. The market will not favor any specific investment objective or set of policies at all times and under all economic circumstances. A fund will experience periods of both high and low returns relative to other funds and other investments. Even if one of our Funds is not favored by the market at a particular time, we believe that the advisor is nonetheless obliged to remain true to the Fund’s objective and policies, and we watch to see that it does so.

[This statement is submitted for the general information of the shareholders of Thornburg Investment Trust. For prospective investors in any fund of Thornburg Investment Trust, this communication must be preceded or accompanied by a prospectus. You may obtain a current copy of the Funds’ prospectus, which describes the Funds’ management fees, expenses and risks, by calling 1-800-847-0200 or by visiting www.thornburg.com/download. Please read the prospectus carefully before investing.]

Investments carry risks, including possible loss of principal. Portfolios investing in bonds have the same interest rate, inflation, and credit risks that are associated with the underlying bonds. The value of bonds will fluctuate relative to changes in interest rates, decreasing when interest rates rise. This effect is more pronounced for longer-term bonds. Unlike bonds, bond funds have ongoing fees and expenses. Investments in lower rated and unrated bonds may be more sensitive to default, downgrades, and market volatility; these investments may also be less liquid than higher rated bonds. Investments in derivatives are subject to the risks associated with the securities or other assets underlying the pool of securities, including illiquidity and difficulty in valuation. Investments in equity securities are subject to additional risks, such as greater market fluctuations. Additional risks may be associated with investments outside the United States, especially in emerging markets, including currency fluctuations, illiquidity, volatility, and political and economic risks. Please see the Funds’ prospectus for a discussion of the risks associated with an investment in the Funds. Investments in the Funds are not FDIC insured, nor are they bank deposits or guaranteed by a bank or any other entity.

Letter to Shareholders
September 30, 2020 (Unaudited)

Dear Shareholder:

We certainly don’t know what will happen over the coming weeks and months, but we’re excited about continued opportunities to deliver for you, given what we see as a rapidly changing market. Some of those changes are cyclical, and we will do our best to see through the cycle, but some changes are secular, and an unexamined acceptance of past truths will be unprofitable at best and dangerous at worst. It is our understanding of and participation in the interconnectedness of markets that is our core competency: We’re built for this.

Thank you so much for your time, and your business.


Jason Brady, cfa Portfolio Manager CEO, President, and Managing Director

Thornburg Limited Term U.S. Government Fund

Investment Goal and Fund Overview

The primary goal of Limited Term U.S. Government Fund is to provide as high a level of current income as is consistent, in the view of the Fund’s investment advisor, with safety of capital. As a secondary goal, the Fund seeks to reduce changes in its share price compared to longer term portfolios.

The Fund is an actively managed, laddered portfolio of short/intermediate-term obligations issued by the U.S. Government, its agencies or instrumentalities with an average maturity of less than five 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 is invested in bonds with longer maturities at the far end of the ladder. The strategy is a good compromise for managing different types of risk.

Performance drivers and detractors for the reporting period ending September 30, 2020

» The Fund generated strong total returns over the trailing 12-month reporting period, but underperformed its longer duration benchmark, the Bloomberg Barclays U.S. Government Intermediate Total Return Index Value Unhedged.

» The Fund’s significant underweighting relative to the benchmark in U.S. Treasury duration was the largest single detractor for the Fund’s performance over the year as rates rapidly declined amid unprecedented action by the Federal Reserve.

» The portfolio maintained a healthy allocation to Agency Mortgage Backed Securities, which provided superior yields relative to what is available in U.S. Treasuries.

» On a go-forward basis, we believe mortgage related securities, backed by the U.S. government, represent significant value, particularly when considering that U.S. treasury rates across the curve sit near historic lows.

» The Fund generated strong total returns and outpaced its benchmark, the Bloomberg Barclays Intermediate U.S. Government/Credit Total Return Index Value Unhedged, by a wide margin during the 12-month reporting period.

» The Fund’s underweighting in U.S. Treasury securities was the largest single detractor over the year as rates rapidly declined amid unprecedented action by the Federal Reserve.

» A defensive posture early on in the period allowed the portfolio to benefit from the flight-to-safety during the rapid decline in equity and credit markets due to COVID-19.

» The Fund’s positioning provided cash reserves for re-deployment when managers saw value in investment grade corporates and asset-backed securities.

» The portfolio shifted significantly into credit exposure at wider spreads in the latter parts of first quarter 2020, allowing the Fund to benefit from the recovery in credit markets over the second and third quarter of the year.

» From a quality perspective, BBB-rated credit securities were the single most positive contributor to performance during the year.

Thornburg Ultra Short Income Fund

Investment Goal and Fund Overview

The Ultra Short Income Fund seeks current income, consistent with preservation of capital.

The Fund is an actively managed, laddered portfolio of investment grade obligations. The Fund seeks to reduce changes in its share value compared to longer duration fixed income portfolios by maintaining a portfolio of investments with a dollar-weighted average duration of normally no more than one half (0.5) of a year. The Fund’s investments are determined by individual security analysis.

Performance drivers and detractors for the reporting period ending September 30, 2020

» The Fund generated strong total returns during the trailing 12-month reporting period, slightly underperforming the Bloomberg Barclays U.S. Aggregate 1-3 Year Total Return Index Value Unhedged USD.

» The Fund’s significant underweighting relative to the benchmark in U.S. Treasury securities was the Fund’s largest single detractor over the year as rates rapidly declined amid unprecedented action by the Federal Reserve.

» A defensive posture led by cash holdings and higher quality credits early on in the period allowed the portfolio to benefit from the flight-to-safety during the rapid decline in equity and credit markets due to the COVID-19 pandemic.

» The portfolio shifted significantly into credit exposure, primarily through short-dated asset-backed securities, at wider spreads in the latter part of first quarter 2020, allowing the Fund to benefit from the recovery in credit markets over the second and third quarter of the year.

» On a go-forward basis, we believe consumer related, short-maturity, quickly amortizing, asset-backed securities represent significant value as the portfolio shifts to a lower duration stance amid historically low rates and longer benchmark durations.

Thornburg Strategic Income Fund

Investment Goal and Fund Overview

Strategic Income Fund’s primary investment goal is to seek a high level of current income. The Fund’s secondary investment goal is some long-term capital appreciation.

The Fund is a global, income-oriented fund with a flexible mandate focused on paying an attractive, sustainable yield. The portfolio invests in a combination of income-producing securities with an emphasis on higher-yielding fixed income.

Performance drivers and detractors for the reporting period ending September 30, 2020

» The Fund generated relatively strong total returns during the trailing 12-month reporting period, slightly underperforming its primary benchmark, the Bloomberg Barclays U.S. Universal Total Return Index Value Unhedged.

» The Fund’s significant underweighting relative to the benchmark in U.S. Treasury securities was the largest single detractor over the year as rates rapidly declined amid unprecedented action by the Federal Reserve.

» A combination of historically high cash holdings and historically low allocations to high yield corporate bonds ahead of the COVID-19 related market volatility was a significant contributor to performance during the 12-month reporting period.

» The Fund’s defensive positioning provided cash reserves for re-deployment when managers saw increasing value in investment grade corporate bonds, high yield corporates, and asset-backed securities in first quarter, 2020.

» The portfolio shifted significantly into credit exposure at wider spreads in the latter part of first quarter 2020, allowing the Fund to benefit from the recovery in credit markets over the second and the third quarter of the year.

» From a quality perspective, Fund holdings in BBB, BB and B-rated securities significantly contributed to positive performance during the year.

Glossary

September 30, 2020 (Unaudited)

The Bloomberg Barclays Intermediate U.S. Government/Credit Total Return Index Value Unhedged is an unmanaged, market-weighted index generally representative of intermediate government and investment-grade corporate debt securities having maturities from one up to ten years.

The Bloomberg Barclays U.S. Government Intermediate Total Return Index Value Unhedged is an unmanaged, market-weighted index generally representative of all public obligations of the U.S. Government, its agencies and instrumentalities having maturities from one up to ten years.

The Bloomberg Barclays U.S. Aggregate 1-3 Year Total Return Index Value Unhedged USD measures the investment grade, U.S. dollar-denominated, fixed-rate taxable bond market with maturities between 1 and 3 years, including Treasuries, government-related and corporate securities, MBS (agency fixed-rate and hybrid ARM passthroughs), ABS, and CMBS.

The Bloomberg Barclays U.S. Universal Total Return Index Value Unhedged represents the union of the U.S. Aggregate Index, U.S. Corporate High-Yield, Investment Grade 144A Index, Eurodollar Index, U.S. Emerging Markets Index, and the non-ERISA eligible portion of the CMBS Index. The index covers USD denominated, taxable bonds that are rated either investment-grade or below investment-grade.

Asset-backed Security (ABS) – A security whose value and income payments are derived from and collateralized (or “backed”) by a specified pool of underlying assets. The pool of assets is typically a group of small and illiquid assets that are unable to be sold individually. Pooling the assets into financial instruments allows them to be sold to general investors, a process called securitization, and allows the risk of investing in the underlying assets to be diversified because each security will represent a fraction of the total value of the diverse pool of underlying assets.

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.

High yield bonds may offer higher yields in return for more risk exposure.

U.S. Treasury securities, such as bills, notes and bonds, are negotiable debt obligations of the U.S. government. These debt obligations are backed by the “full faith and credit” of the government and issued at various schedules and maturities. Income from Treasury securities is exempt from state and local, but not federal, taxes.

A bond credit rating assesses the financial ability of a debt issuer to make timely payments of principal and interest. Ratings of AAA (the highest), AA, A, and BBB are investment-grade quality. Ratings of BB, B, CCC, CC, C and D (the lowest) are considered below investment grade, speculative grade, or junk bonds. Investments in mortgage-backed securities (MBS) may bear additional risk.

NOTE 1 – ORGANIZATION

Thornburg Limited Term U.S. Government Fund (the “Limited Term U.S. Government Fund”), Thornburg Limited Term Income Fund (the “Limited Term Income Fund”), Thornburg Ultra Short Income Fund (the “Ultra Short Income Fund”, prior to September 30, 2020, the Low Duration Income Fund) and Thornburg Strategic Income Fund (the “Strategic Income Fund”), collectively the (“Funds”), are diversified series of Thornburg Investment Trust (the “Trust”). The Trust is 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 "1940 Act"). The Funds are currently four of twenty-two 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.

Limited Term U.S. Government Fund: The Fund’s primary objective is to provide a high level of current income as is consistent, in the view of the Trust’s investment advisor, Thornburg Investment Management, Inc. (the “Advisor”), with safety of capital. As a secondary objective, the Fund seeks to reduce changes in its share price compared to longer term portfolios. The Fund’s investments subject it to risks including, but not limited to, management risk, interest rate risk, prepayment and extension risk, credit risk, market and economic risk, liquidity risk, and structured products risk. Please see the Fund’s prospectus for a discussion of the risks associated with an investment in the Fund.

All countries are vulnerable economically to the impact of a public health crisis, such as the novel virus known as COVID-19. Such crises may depress consumer demand, disrupt supply chains, slow economic growth, and potentially lead to market closures, travel restrictions, government-imposed shutdowns, and quarantines, all of which could adversely affect the economies of many of the markets in which the Funds invest, and which could in turn lead to declines in the value of the Funds’ invest, and which could in turn lead to declines in the value of the Funds’ investments or decrease the liquidity of those investments.

As of September 30, 2020, the Funds currently offer from one to seven classes of shares of beneficial interest.

Each class of shares of the Funds 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 C shares are sold at net asset value without a sales charge at the time of purchase, but are subject to a contingent deferred sales charge upon redemption within one year of purchase, and bear both a service fee and a distribution fee, (iii) Class I and Class R5 shares are sold at net asset value without a sales charge at the time of purchase and may be subject to a service fee, (iv) Class R3 shares are sold at net asset value without a sales charge, but bear both a service fee and a distribution fee, (v) Class R4 shares are sold at net asset value without a sales charge at the time of purchase but bear a service fee, (vi) Class R6 shares are sold at net asset value without a sales charge at the time of purchase, and (vii) the respective classes may have different reinvestment privileges and conversion rights. Additionally, each Fund may allocate among its classes certain expenses, to the extent allocable to specific classes, including administration fees, transfer agent fees, government registration fees, certain printing and postage costs, and legal expenses. Currently, class specific expenses of the Funds are limited to distribution and service fees, transfer agent fees, and certain registration and filing fees.

At September 30, 2020, the following class of shares are offered in each respective Fund:

	Class A	Class C	Class I	Class R3	Class R4	Class R5	Class R6

NOTE 3 – SECURITY VALUATION

Valuation of the Funds’ portfolio investment securities is performed in accordance with policies and procedures adopted by and under the oversight of the Trustees.

Valuation of Securities: Securities and other portfolio investments which are listed or traded on a United States securities exchange are valued at the last reported sale price on the valuation date. Investments listed or traded on an exchange for which there has been no sale that day are valued at the mean between the last reported bid and asked prices on that valuation date. Portfolio investments reported by NASDAQ are valued at the official closing price on the valuation date. If an investment is traded on more than one exchange, the investment is considered traded on the exchange that is normally the primary market for that investment. Securities and other portfolio investments which are listed or traded on exchanges outside the United States are valued at the last price or the closing price of the investment on the exchange that is normally the primary market for the investment, as of the close of the exchange preceding the Fund’s valuation date. Foreign investments listed or traded on an exchange for which there has been no sale that day are valued at the mean between the last reported bid and asked prices on that valuation date.

investments held by the Fund may be valued using alternative methods. The Committee customarily obtains valuations in these instances from pricing service providers approved by the Audit Committee. Pricing service providers ordinarily calculate valuations using multi-factor models to adjust market prices based upon various inputs, including exchange data, depository receipt prices, futures, index data and other data.

Investments in open-end U.S. mutual funds are valued at net asset value (“NAV”) each business day.

Various inputs are used in calculating valuations for the Funds’ investments. These inputs are generally summarized according to the three-level hierarchy below:

Level 1: Quoted prices in active markets for identical investments.

Level 3: Significant unobservable inputs (including the Committee’s own assumptions in calculating the fair values of investments).

Pursuant to a service plan under Rule 12b-1 of the 1940 Act, the Funds may reimburse to the Distributor an amount not to exceed .25 of 1% per annum of the average daily net assets attributable to the applicable Class A, Class C, Class I, Class R3, Class R4, and Class R5 shares of the Limited Term U.S. Government Fund, Limited Term Income Fund and Strategic Income Fund and .20 of 1% per annum of the average daily net assets attributable to the applicable Class A and Class I of the Ultra Short Income Fund for payments made by the Distributor to securities dealers and other financial institutions to obtain various shareholder and distribution related services. For the year ended September 30, 2020, there were no 12b-1 service plan fees charged for Class I or Class R5 shares. Class R6 shares are not subject to a service plan. The Advisor and Distributor each may pay out of its own resources additional expenses for distribution of each Funds’ shares and shareholder services.

The Trust has also adopted a distribution plan pursuant to Rule 12b-1, applicable only to the Funds’ Class C and Class R3 shares, under which the Funds compensate the Distributor for services in promoting the sale of Class C and R3 shares of the Funds at an annual rate of up to .25 of 1% per annum of the average daily net assets attributable to Class C shares of Limited Term U.S. Government Fund and Limited Term Income Fund, and .75 of 1% per annum of the average daily net assets attributable to Class C shares of Strategic Income Fund, and an annual rate of up to .25 of 1% per annum of the average daily net assets attributable to Class R3 shares. Total fees incurred by each class of shares of the Funds under their respective service and distribution plans for the year ended September 30, 2020 are set forth in the Statements of Operations.

The Advisor has contractually agreed to waive fees and reimburse expenses incurred by the Funds. The agreement may be terminated by the Funds at any time, but may not be terminated by the Advisor before February 1, 2021 as to the Limited Term U.S Government Fund, Strategic Income Fund, or the Class R3, R4, R5, or R6 shares of the Limited Term Income Fund, and may not be terminated by the Advisor before September 30, 2021 as to the Ultra Short Income Fund or the Class I shares of the Limited Term Income Fund, unless the Advisor ceases to be the investment advisor to the Funds prior to such dates. The Advisor may recoup amounts waived or reimbursed during the year ended September 30, 2020 if, during the fiscal year, expenses fall below the contractual limit that was in place at the time these fees and expenses were waived or reimbursed. The Advisor will not recoup fees or expenses as described in the preceding sentence if that recoupment would cause the Fund’s total annual operating expenses (after the recoupment is taken into account) to exceed the lesser of: (a) the expense cap that was in place at the time the waiver or reimbursement occurred; or (b) the expense cap that is in place at the time of the recoupment.

NOTE 8 – DERIVATIVE FINANCIAL INSTRUMENTS WITH OFF-BALANCE
SHEET RISK AND FOREIGN INVESTMENT RISK

The outstanding forward currency contracts in the table located in the Strategic Income Fund’s Schedule of Investments, which were entered into with State Street Bank and Trust Company (“SSB”), were entered into pursuant to an International Swaps and Derivatives Association (“ISDA”) Master Agreement. In the event of a default or termination under the ISDA Master Agreement with SSB, the non-defaulting party has the right to close out all outstanding forward currency contracts between the parties and to net any payment amounts under those contracts, resulting in a single net amount payable by one party to the other.

Because the ISDA Master Agreement with SSB does not result in an offset of reported amounts of financial assets and liabilities in the Strategic Income Fund’s Statement of Assets and Liabilities unless there has been an event of default or termination event under that agreement, the Fund does not net its outstanding forward currency contracts for purposes of the disclosure in the Strategic Income Fund’s Statement of Assets and Liabilities. Instead the Fund recognizes the unrealized appreciation (depreciation) on those forward currency contracts on a gross basis in the Strategic Income Fund’s Statement of Assets and Liabilities.

	Type of Derivative^(a)	Counter Party	Asset Derivatives	Liability Derivatives	Net Amount
Strategic Income Fund	Foreign currency contracts	SSB	$ 5,282	$ —	$ 5,282

(a)	Generally, the Statement of Assets and Liabilities location for forward currency contracts is Assets - Unrealized appreciation on forward currency contracts for asset derivatives and Liabilities - Unrealized depreciation on forward currency contracts for liabilities derivatives.

Report of Independent Registered Public Accounting Firm
Thornburg Fixed Income Funds

To the Board of Trustees of Thornburg Investment Trust and Shareholders of Thornburg Limited Term U.S. Government Fund, Thornburg Limited Term Income Fund, Thornburg Ultra Short Income Fund and Thornburg Strategic Income Fund

Opinions on the Financial Statements

We have audited the accompanying statements of assets and liabilities, including the schedules of investments, of Thornburg Limited Term U.S. Government Fund, Thornburg Limited Term Income Fund, Thornburg Ultra Short Income Fund (formerly known as Thornburg Low Duration Income Fund) and Thornburg Strategic Income Fund (four of the funds constituting Thornburg Investment Trust, hereafter collectively referred to as the "Funds") as of September 30, 2020, the related statements of operations for the year ended September 30, 2020, the statements of changes in net assets for each of the two years in the period ended September 30, 2020, including the related notes, and the financial highlights for each of the periods indicated therein (collectively referred to as the “financial statements”). In our opinion, the financial statements present fairly, in all material respects, the financial position of each of the Funds as of September 30, 2020, the results of each of their operations for the year then ended, the changes in each of their net assets for each of the two years in the period ended September 30, 2020 and each of the financial highlights for each of the periods indicated therein in conformity with accounting principles generally accepted in the United States of America.

Basis for Opinions

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. Our procedures included confirmation of securities owned as of September 30, 2020 by correspondence with the custodian, agent banks, transfer agent and brokers; when replies were not received from brokers, we performed other auditing procedures. We believe that our audits provide a reasonable basis for our opinions.

and performance metrics for the Fund relative to its benchmark and to a selected peer group of funds, prepared by an independent financial analyst firm engaged by the independent Trustees; (6) the Fund’s cash flows; (7) the analysis and observations of an independent mutual fund analyst firm respecting the Fund’s investment performance relative to a category of funds selected by that firm; (8) comparison of the Fund’s annualized return to the Fund’s benchmark index or indices over various periods since the Fund’s inception; and (9) various risk and return statistics. The Trustees noted their understanding that strategies pursued for a Fund may produce intermittent lower relative performance, that such Funds have in the past returned to favor as conditions changed or the strategies of those Funds gained traction, and the Advisor has in general been successful in remediating lower relative performance of Funds in cases where execution of investment strategies had contributed to lower performance. The Trustees also noted in their evaluations that to the extent pertinent they attach additional significance to the performance of each Fund from the perspective of longer-term shareholders.

Further detail considered by the Trustees with respect to the investment performance of each Fund is set forth below:

•	Thornburg Limited Term U.S. Government Fund – the Trustees considered that while the Fund underperformed its benchmark index for the year-to-date, one-, three-, five-, ten-, and fifteen-year periods, the Fund outperformed its Morningstar category over all such periods and ranked in the first or second quartile of a selected peer group of funds for the year-to-date, one, three-, five- and ten-year periods. The Trustees also considered that the Fund has met its primary objective of providing current income while preserving the Fund’s capital.
•	Thornburg Limited Term Income Fund – the Trustees considered that while the Fund underperformed its benchmark index for the year-to-date, one-, and three-year periods, the Fund outperformed its benchmark index over the five-, ten, and fifteen-year periods, outperformed its Morningstar category over all periods, and ranked in the first quartile of a selected peer group of funds for the year-to-date, one, three-, five- and ten-year periods. The Trustees also considered that the Fund has met its primary objective of providing current income while preserving the Fund’s capital.
•	Thornburg Ultra Short Income Fund – the Trustees considered that, while the Fund underperformed its benchmark index for the year-to-date, one-, and three-year periods, the extent of that underperformance was not significant, and the Fund outperformed its Morningstar category in each of those periods and outperformed its benchmark index over the five-year period. Noting that the Advisor had proposed, and the Trustees had approved, changes to the Fund’s principal investment strategies which are expected to take effect at the end of the Fund’s 2020 fiscal year, the Trustees considered that, for the year-to-date, one-, three-, and five-year periods, the Fund’s investment performance would have ranked in the first quartile of a selected peer group of funds that reflect the new strategies that the Fund will pursue. The Trustees also observed that the Fund has met its primary objective of generating current income while preserving the Fund’s capital.
•	Thornburg Strategic Income Fund – the Trustees considered that while the Fund underperformed its benchmark indices for the year-to-date, one-, three-, and five-year periods, the Fund outperformed its benchmark indices over the ten-year period and since the Fund’s inception, outperformed its Morningstar category over all such periods, and ranked in the first or second quartile of a selected peer group of funds for the year-to-date, one, three-, five- and ten-year periods. The Trustees also considered that the Fund has met its primary objective of seeking a high level of current income.

Comparisons of Fee and Expense Levels. Information noted by the Trustees as having been considered in this context included a variety of comparative data respecting the Funds’ fee and expense levels. This information included comparisons of each Fund’s advisory fee and overall Fund expenses to median and average fees and expenses charged to funds in the applicable Morningstar category, comparisons of the advisory fee and total expenses for multiple Fund share classes to the fee levels and expenses of fund peer groups selected from the category by an independent mutual fund analyst firm engaged by the independent Trustees, the perspectives and advice from that mutual fund analyst firm respecting comparisons of fund fee levels and expenses to fund peer groups, and other information. In evaluating comparative fee and expense data, the Trustees considered whether the advisory fees charged to each Fund were at least generally comparable to the comparatives presented, and whether those advisory fees and overall Fund expense levels were within the range of figures established for the selected peer groups.

Further detail considered by the Trustees with respect to the comparison of the fee and expense levels of each Fund is set forth below:

•

Thornburg Limited Term U.S. Government Fund – Comparative fee and expense data considered by the Trustees showed that the level of total expense for one share class of the Fund was higher than median and average levels charged to funds in the applicable Morningstar category, and that the level of total expense for a second share class was lower than the median and average levels for that category. Peer group data showed that the Fund’s stated advisory fee was lower than the medians of the two peer groups considered, and that the total expense levels of two representative share classes were higher than the medians of their respective peer groups but comparable to other funds in the peer groups.

•	Thornburg Limited Term Income Fund – Comparative fee and expense data considered by the Trustees showed that the level of total expense for one share class of the Fund was higher than median and average levels charged to funds in the applicable Morningstar category, and that the level of total expense for a second share class was, after fee waivers and expense reimbursements, lower than the median and average levels for that category. Peer group data showed that the Fund’s stated advisory fee was higher than the medians of the two peer groups considered but comparable to other funds in the peer groups, that the total expense level of one representative share class was higher than the median of its peer group but comparable to other funds in the peer group, and that the total expense level of another representative share class was equal to the median of its peer group after fee waivers and expense reimbursements.
•	Thornburg Ultra Short Income Fund – In considering the fees and expenses of the Fund, the Trustees considered the application of the fee waivers and expense reimbursements that are scheduled to take effect at the end of the Fund’s 2020 fiscal year, and compared the Fund’s fees and expenses to a Morningstar category and peer groups of funds that reflect the forthcoming changes in the Fund’s principal investment strategies. Comparative fee and expense data considered by the Trustees showed that, after application of those fee waivers and expense reimbursements, the level of total expense for one share class of the Fund was higher than median and average levels charged to funds in the applicable Morningstar category, and that the level of total expense for a second share class was lower than the median and average levels for that category. Peer group data showed that the Fund’s stated advisory fee was higher than the median of one peer group considered but comparable to other funds in that peer group, and was equal to the median of another peer group considered. Peer group data also showed that the total expense levels of two representative share classes were lower than the medians of their respective peer groups after waivers of fees and reimbursement of expenses.
•	Thornburg Strategic Income Fund – Comparative fee and expense data considered by the Trustees showed that, after fee waivers and expense reimbursements, the level of total expense for one share class of the Fund has higher than the median but lower than the average levels charged to funds in the applicable Morningstar category, and that the level of total expense for a second share class was lower than the median and average levels for that category. Peer group data showed that the Fund’s stated advisory fee was higher than the medians of the two peer groups considered but comparable to other funds in the peer groups, that the total expense level of one representative share class was higher than the median of its peer group but comparable to other funds in the peer group after fee waivers and expense reimbursements, and that the total expense level of another representative share class was lower than the median of its peer group after fee waivers and expense reimbursements.

other funds in peer groups selected by an independent mutual fund analyst firm, the effects of the breakpoint structure and other expense factors realized by certain funds of the Trust as their asset levels had increased, the Advisor’s undertakings to waive or reimburse certain fees and expenses for certain Funds and share classes, and the Advisor’s expenditures from its own profits and resources to maintain staffing levels, pay competitive levels of compensation, and add to its electronic and information technology systems to maintain or improve service levels. The information provided demonstrated to the Trustees that the Funds’ advisory fee breakpoint structures are reasonable in relation to the structures observed in the other funds in their respective peer groups, and that shareholders may be expected to benefit from any economies of scale, due to the advisory agreement’s breakpoint fee structure for each Fund and other factors.

Potential Ancillary Benefits. In reviewing potential benefits to the Advisor because of its relationship to the Funds, the Trustees considered explanations from the Advisor respecting its receipt of certain research services from broker dealers, and the benefits to both the Funds and the Advisor of the Advisor’s expansion of its staffing, compliance, and systems capabilities and other resources to serve a broader variety of investment management clients. No unusual or unfair benefits to the Advisor from its relationship to the Funds were identified by the Trustees.

Thornburg Short Duration Municipal Fund

Investment Goal and Fund Overview

The primary goal of Short Duration Municipal Fund is to provide current income exempt from federal income tax, consistent with preservation of capital.

The Fund is an actively managed, laddered portfolio of municipal bonds with maturities not exceeding 5 years. Actively laddering portfolios involves building a portfolio of bonds with staggered maturities that are over-weighted or under-weighted based on our assessment of market risks and individual credit opportunities. A portion of the portfolio matures each year and cash from maturing bonds is invested in bonds with longer maturities.

Performance drivers and detractors for the reporting period ending September 30, 2020

» The Fund (Class I shares) underperformed the ICE BofAML 1-3 Year U.S. Municipal Securities Index by 135 basis points (bps) on a gross-of-fee basis during the 12-month period ending September 30, 2020.

» Duration and yield curve positioning had a negative effect on the Fund’s relative performance as the portfolio ended the year with a duration 0.98 years shorter than its index. Performance due to parallel shifts in the yield curve detracted 94 bps, while performance due to non-parallel shifts detracted 39 bps from relative performance during the period.

» Security selection was also a detractor from performance during the period, accounting for 28 bps of relative performance.

Thornburg New York Intermediate Municipal Fund

Investment Goal and Fund Overview

The primary investment goal of Intermediate New York Fund is to obtain as high a level of current income exempt from federal, New York State and New York City individual income taxes as is consistent, in the view of the Fund’s 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.

The Fund is an actively managed, laddered portfolio of New York and US territory municipal bonds with a dollar weighted average maturity of normally three to ten years and with maturities not exceeding 20 years. Actively laddering portfolios involves building a portfolio of bonds with staggered maturities that are over-weighted or under-weighted based on our assessment of market risks and individual credit opportunities. A portion of the portfolio matures each year and cash from maturing bonds is invested in bonds with longer maturities.

Performance drivers and detractors for the reporting period ending September 30, 2020

» The Fund’s performance due to its duration and yield curve positioning had a negative effect on relative performance as the portfolio ended the period with a duration 0.44 years shorter than its index.

Yield Curve – A line that plots the interest rates, at a set point in time, of bonds having equal credit quality, but differing maturity dates.

Parallel and non-parallel shifts – Relates to the movement of the yield curve. A parallel shift means the yield curve moves up or down the same amount across the entire curve (short and long ends move). A non-parallel shift means the short end and long end move at different amounts. For example, the short end may move up 10 basis points while the long-end may move up 20 basis points.

All countries are vulnerable economically to the impact of a public health crisis, such as the novel virus known as COVID-19. Such crises may depress consumer demand, disrupt supply chains, slow economic growth, and potentially lead to market closures, travel restrictions, government-imposed shutdowns, and quarantines, all of which could adversely affect the economies of many of the markets in which the Funds invest, and which could in turn lead to declines in the value of the Funds’ invest, and which could in turn lead to declines in the value of the Funds’ investments or decrease the liquidity of those investments.

NOTE 2 – SIGNIFICANT ACCOUNTING POLICIES

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 dividends, 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 and distributions are paid and are reinvested in additional shares of the Funds 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 first call dates or maturity dates using the effective yield method of the respective investments. These amounts are included in Investment Income in the Statement of Operations.

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.

Security Valuation: All investments in securities held by the Funds are valued as described in Note 3.

The Advisor and Distributor each may pay out of its own resources additional expenses for distribution of each 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 C and Class D shares, under which the Funds compensate the Distributor for services in promoting the sale of Class C and Class D shares of the Funds at an annual rate of up to .25 of 1% per annum of the average daily net assets attributable to Class C and Class D shares.

Report of Independent Registered Public Accounting Firm
Thornburg Municipal Funds

To the Board of Trustees of Thornburg Investment Trust and Shareholders of Thornburg Short Duration Municipal Fund, Thornburg Limited Term Municipal Fund, Thornburg California Limited Term Municipal Fund, Thornburg New Mexico Intermediate Municipal Fund, Thornburg New York Intermediate Municipal Fund, Thornburg Intermediate Municipal Fund and Thornburg Strategic Municipal Income Fund

Opinions on the Financial Statements

We have audited the accompanying statements of assets and liabilities, including the schedules of investments, of Thornburg Short Duration Municipal Fund (formerly known as Thornburg Low Duration Municipal Fund), Thornburg Limited Term Municipal Fund, Thornburg California Limited Term Municipal Fund, Thornburg New Mexico Intermediate Municipal Fund, Thornburg New York Intermediate Municipal Fund, Thornburg Intermediate Municipal Fund and Thornburg Strategic Municipal Income Fund (seven of the funds constituting Thornburg Investment Trust, hereafter collectively referred to as the "Funds") as of September 30, 2020, the related statements of operations for the year ended September 30, 2020, the statements of changes in net assets for each of the two years in the period ended September 30, 2020, including the related notes, and the financial highlights for each of the five years in the period ended September 30, 2020 (collectively referred to as the “financial statements”). In our opinion, the financial statements present fairly, in all material respects, the financial position of each of the Funds as of September 30, 2020, the results of each of their operations for the year then ended, the changes in each of their net assets for each of the two years in the period ended September 30, 2020 and each of the financial highlights for each of the five years in the period ended September 30, 2020 in conformity with accounting principles generally accepted in the United States of America.

Basis for Opinions

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. Our procedures included confirmation of securities owned as of September 30, 2020 by correspondence with the custodian, transfer agent and brokers; when replies were not received from brokers, we performed other auditing procedures. We believe that our audits provide a reasonable basis for our opinions.

Expense Example
September 30, 2020 (Unaudited)

As a shareholder of the Fund, you incur two types of costs:

(1)	transaction costs, including

(a)	sales charges (loads) on purchase payments, for Class A shares;
(b)	a deferred sales charge on redemptions of any part or all of a purchase of $1 million of Class A shares within 12 months of purchase;
(c)	a deferred sales charge on redemptions of Class C shares within 12 months of purchase;

(2)	ongoing costs, including management fees; distribution and/or service (12b-1) fees; and other Fund expenses.

As in past years, the Trustees noted particularly their assessments of the Advisor’s personnel developed in formal and informal meetings throughout the year, measures to expand and improve the depth and experience of the Advisor’s staff, and the Advisor’s collaborative approach to investment management, continued commitment to observance of compliance and regulatory requirements in managing investments by the Funds, responsiveness to the Trustees, and other factors and circumstances.

The Trustees also noted their consideration of information provided to them at their request in anticipation of their annual evaluation of the Advisor’s services, including the following items of information respecting the investment performance of each Fund: (1) the Fund’s absolute investment performance and achievement of stated objectives; (2) the Advisor’s explanations and written and oral commentary on the Fund’s performance in the context of the Fund’s objectives and reasonable expectations, and business, market, and economic conditions; (3) performance data for the ten most recent calendar years (or lesser number of years for each Fund having fewer calendar years of operations), comparing the Fund’s annual investment returns to a category of funds selected by an independent mutual fund analyst firm, to one or more broad-based securities indices, and to the applicable Morningstar category of funds; (4) the Fund’s investment performance for the three-month, year-to-date, one-year, three-year, five-year, since inception and, if applicable, ten-year and fifteen-year periods ending with the second quarter of the current year, comparing the Fund’s annualized returns to mutual fund categories selected by independent mutual fund analyst firms, to one or more broad-based securities indices, and to the applicable Morningstar category of funds, and assigning a percentage rank to the Fund’s performance for each period relative to each of the fund categories; (5) analyses of specified risk and performance metrics for the Fund relative to its benchmark and to a selected peer group of funds, prepared by an independent financial analyst firm engaged by the independent Trustees; (6) the Fund’s cash flows; (7) the analysis and observations of an independent mutual fund analyst firm respecting the Fund’s investment performance relative to a category of funds selected by that firm; (8) comparison of the Fund’s annualized return to the Fund’s benchmark index or indices over various periods since the Fund’s inception; and (9) various

risk and return statistics. The Trustees noted their understanding that strategies pursued for a Fund may produce intermittent lower relative performance, that such Funds have in the past returned to favor as conditions changed or the strategies of those Funds gained traction, and the Advisor has in general been successful in remediating lower relative performance of Funds in cases where execution of investment strategies had contributed to lower performance. The Trustees also noted in their evaluations that to the extent pertinent they attach additional significance to the performance of each Fund from the perspective of longer-term shareholders.

Further detail considered by the Trustees with respect to the investment performance of each Fund is set forth below:

•	Thornburg Short Duration Municipal Fund – the Trustees considered that the Fund underperformed its benchmark index and Morningstar category for the year-to-date, one-, three-, and five-year periods, and ranked in the fourth quartile of a selected peer group of funds for all such periods. The Trustees noted, however, that the extent of the underperformance was not significant, considered explanations from the Advisor respecting the effects of market and economic conditions on the Fund’s investment performance during relevant periods, and observed that the Fund has met its objective of generating current income that is exempt from federal income tax while preserving the Fund’s capital.
•	Thornburg Limited Term Municipal Fund – the Trustees considered that, while the Fund underperformed its benchmark index for the year-to-date, one-, three-, five-, ten-, and fifteen-year periods, the extent of that underperformance was not significant, and the Fund outperformed its Morningstar category over each such period and also ranked in the first quartile of a selected peer group of funds for the year-to-date, one-, three-, five, and ten-year periods. The Trustees also observed that the Fund has met its primary objective of generating current income that is exempt from federal income tax while preserving the Fund’s capital.
•	Thornburg California Limited Term Municipal Fund – the Trustees considered that, while the Fund underperformed its benchmark index for the year-to-date, one-, three-, five-, ten-, and fifteen-year periods, and underperformed its Morningstar category for certain of those periods, the extent of that underperformance was not significant, and the Fund outperformed its Morningstar category in certain other periods and ranked in the first or second quartile of a selected peer group of funds for the year-to-date, one-, and ten-year periods. The Trustees also observed that the Fund has met its primary objective of generating current income that is exempt from federal and California state individual income taxes while preserving the Fund’s capital.
•	Thornburg New Mexico Intermediate Municipal Fund – the Trustees considered that, while the Fund underperformed its benchmark index for the year-to-date, one-, three-, five-, ten-, and fifteen-year periods, and underperformed its Morningstar category for certain of those periods, the extent of that underperformance was not significant, and the Fund outperformed its Morningstar category in certain other periods. The Trustees considered comparisons of the Fund’s performance to a selected peer group of Funds but noted the reduced utility of those comparisons given the lack of other funds focused on investments in New Mexico debt obligations. The Trustees also observed that the Fund has met its primary objective of generating current income that is exempt from federal and New Mexico state individual income taxes while preserving the Fund’s capital.
•	Thornburg New York Intermediate Municipal Fund – the Trustees considered that, while the Fund underperformed its benchmark index for the year-to-date, one-, three-, five-, ten-, and fifteen-year periods, the extent of that underperformance was not significant, and the Fund outperformed its Morningstar category over each such period except the three- and five-year periods and ranked in the first or second quartiles of a selected peer group of funds for the year-to-date, one-, and ten-year periods. The Trustees also observed that the Fund has met its primary objective of generating current income that is exempt from federal and New York state and city individual income taxes while preserving the Fund’s capital.
•	Thornburg Intermediate Municipal Fund – the Trustees considered that, while the Fund underperformed its benchmark index for the year-to-date, one-, three-, five-, ten-, and fifteen-year periods, and underperformed its Morningstar category for certain of those periods, the extent of that underperformance was not significant, and the Fund outperformed its Morningstar category in certain other periods and ranked in the top three quartiles of a selected peer group of funds over most periods. The Trustees also observed that the Fund has met its primary objective of generating current income that is exempt from federal income tax while preserving the Fund’s capital.
•	Thornburg Strategic Municipal Income Fund – the Trustees considered that, while the Fund underperformed its benchmark index for the year-to-date, one-, three-, five-, and ten-year periods, and underperformed its Morningstar category for certain of those periods, the extent of that underperformance was not significant, and the Fund outperformed its Morningstar category in certain other periods and ranked in the top three quartiles of a selected peer group of funds over most periods. The Trustees also observed that the Fund has met its primary objective of generating a high level current income that is exempt from federal income tax.

the advisory fee and total expenses for one or more Fund share classes to the fee levels and expenses of fund peer groups selected from the category by an independent mutual fund analyst firm engaged by the independent Trustees, the perspectives and advice from that mutual fund analyst firm respecting comparisons of fund fee levels and expenses to fund peer groups, and other information. In evaluating comparative fee and expense data, the Trustees considered whether the advisory fees charged to each Fund were at least generally comparable to the comparatives presented, and whether those advisory fees and overall Fund expense levels were within the range of figures established for the selected peer groups.

Further detail considered by the Trustees with respect to the comparison of the fee and expense levels of each Fund is set forth below:

•	Thornburg Short Duration Municipal Fund – Comparative fee and expense data considered by the Trustees showed that, after fee waivers and expense reimbursements, the level of total expense for one share class of the Fund was higher than the median and average levels charged to funds in the applicable Morningstar category, and that the level of total expense for a second share class was lower than the median and average levels for that category. Peer group data showed that the Fund’s stated advisory fee was higher than the medians of the two peer groups considered but comparable to other funds in the peer groups, and that the total expense levels of two representative share classes were higher than the medians of their respective peer groups after waivers of fees and reimbursement of expenses but comparable to other funds in the peer groups.
•	Thornburg Limited Term Municipal Fund – Comparative fee and expense data considered by the Trustees showed that the level of total expense for one share class of the Fund was higher than the median and average levels charged to funds in the applicable Morningstar category, and that the level of total expense for a second share class was lower than the median and average levels for that category. Peer group data showed that the Fund’s stated advisory fee was lower than the medians of the two peer groups considered, and that the total expense levels of two representative share classes were comparable to the medians of their respective peer groups.
•	Thornburg California Limited Term Municipal Fund – Comparative fee and expense data considered by the Trustees showed that, after fee waivers and expense reimbursements, the level of total expense for one share class of the Fund was higher than the median and average levels charged to funds in the applicable Morningstar category, and that the level of total expense for a second share class was lower than the median and average levels for that category. Peer group data showed that the Fund’s stated advisory fee was higher than the medians of the two peer groups considered but comparable to other funds in the peer groups, and that the total expense levels of two representative share classes were equal to or lower than the medians of their respective peer groups after waivers of fees and reimbursement of expenses.
•	Thornburg New Mexico Intermediate Municipal Fund – Comparative fee and expense data considered by the Trustees showed that the level of total expense for one share class of the Fund was higher than the median and average levels charged to funds in the applicable Morningstar category, and that the level of total expense for a second share class was, after fee waivers and expense reimbursements, lower than the median and average levels for that category. Peer group data showed that the Fund’s stated advisory fee was higher than the medians of the two peer groups considered but comparable to other funds in the peer groups, and that the total expense levels of two representative share classes were higher than the medians of their respective peer groups after waivers of fees and reimbursement of expenses but comparable to other funds in the peer groups.
•	Thornburg New York Intermediate Municipal Fund – Comparative fee and expense data considered by the Trustees showed that, after fee waivers and expense reimbursements, the level of total expense for one share class of the Fund was higher than the median and average levels charged to funds in the applicable Morningstar category, and that the level of total expense for a second share class was lower than the median and average levels for that category. Peer group data showed that the Fund’s stated advisory fee was higher than the medians of the two peer groups considered but comparable to other funds in the peer groups, and that the total expense levels of two representative share classes were higher than the medians of their respective peer groups after waivers of fees and reimbursement of expenses but comparable to other funds in the peer groups.
•	Thornburg Intermediate Municipal Fund – Comparative fee and expense data considered by the Trustees showed that, after fee waivers and expense reimbursements, the level of total expense for one share class of the Fund was higher than the median and average levels charged to funds in the applicable Morningstar category, and that the level of total expense for a second share class was lower than the median and average levels for that category. Peer group data showed that the Fund’s stated advisory fee was higher than the medians of the two peer groups considered but comparable to other funds in the peer groups, and that the total expense levels of two representative share classes after waivers of fees and reimbursement of expenses were comparable to the medians of their respective peer groups.

Peer group data showed that the Fund’s stated advisory fee was higher than the medians of the two peer groups considered but comparable to other funds in the peer groups, and that the total expense levels of two representative share classes were lower than or comparable to the medians of their respective peer groups after fee waivers and expense reimbursements.

Potential Economies of Scale. In reviewing the extent to which economies of scale would be realized by each Fund as it grows and whether fee levels reflect potential economies of scale, the Trustees considered the breakpoint structure for advisory fees chargeable to each Fund, comparisons of the fee breakpoint structure for each Fund with breakpoint structures (or the absence of such structures) for other funds in peer groups selected by an independent mutual fund analyst firm, the effects of the breakpoint structure and other expense factors realized by certain funds of the Trust as their asset levels had increased, the Advisor’s undertakings to waive or reimburse certain fees and expenses for certain Funds and share classes, and the Advisor’s expenditures from its own profits and resources to maintain staffing levels, pay competitive levels of compensation, and add to its electronic and information technology systems to maintain or improve service levels. The information provided demonstrated to the Trustees that the Funds’ advisory fee breakpoint structures are reasonable in relation to the structures observed in the other funds in their respective peer groups, and that shareholders may be expected to benefit from any economies of scale, due to the advisory agreement’s breakpoint fee structure for each Fund and other factors.

Thornburg Capital Management Fund

Investment Goal and Fund Overview

Thornburg Capital Management Fund (TCMF) was started with the goal of providing superior risk exposures -- higher returns and lower costs -- for cash management across the Thornburg family of funds. By combining the cash balances of eligible Thornburg Investment Trust portfolios into a single pool of very high quality, short term liquid instruments, we reduce the costs of investing and significantly diversify and reduce risk exposures in any given portfolio.

The creation and management of the Fund helps illustrate our long-standing culture of efficient capital stewardship, benefiting all eligible portfolios through reduced transaction costs and more efficient management.

Performance drivers and detractors for the reporting period ending September 30, 2020

» The Fund generated strong total returns and outpaced its benchmark, the FTSE 1-Month Treasury Bill Index, by a decent margin during the trailing 12-month reporting period.

» Over the reporting period, the Fund accomplished its goal of "safety of capital" by providing a share price for the TCMF of $10.00 that has not fluctuated since inception.

» The Fund has matched or beat its benchmark for all standard time periods since inception.

» Throughout the life of the strategy, the Fund has never suffered a default on any cash equivalent investment.

NOTE 1 – ORGANIZATION

Thornburg Capital Management 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 "1940 Act"). The Fund is currently one of twenty-two 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 investment objective is to seek current income consistent with liquidity management and safety of capital. The Fund’s investments subject it to risks including, but not limited to, management risk, interest rate risk, prepayment and extension risk, credit risk, market and economic risk, foreign investment risk, liquidity risk and diversification risk. Please see the Fund’s prospectus for a discussion of the risks associated with an investment in the Fund.

All countries are vulnerable economically to the impact of a public health crisis, such as the novel virus known as COVID-19. Such crises may depress consumer demand, disrupt supply chains, slow economic growth, and potentially lead to market closures, travel restrictions, government-imposed shutdowns, and quarantines, all of which could adversely affect the economies of many of the markets in which the Fund invests, and which could in turn lead to declines in the value of the Fund’s investments or decrease the liquidity of those investments.

As of September 30, 2020, the Fund currently offers one class of shares of beneficial interest: Institutional Class (“Class I”). This class of shares of the Fund represents all interest in the portfolio of investments. 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. All expenses are allocated to the class including administration fees, transfer agent fees, government registration fees, printing and postage costs, and legal expenses.

Shares of the Fund are issued solely in private placement transactions that do not involve any “public offering” within the meaning of Section (4)2 of the 1933 Act. Investments in the Fund may only be made by investment companies, or other persons that are “accredited investors” within the meaning of Regulation D under the 1933 Act. Thornburg Investment Management, Inc. (the "Advisor"), acting as the agent for the other series of the Trust, will affect all purchases and sells of shares of the Fund on behalf of any series of the Trust.

NOTE 2 – SIGNIFICANT ACCOUNTING POLICIES

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.

Allocation of Expenses: 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.

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 dividends, 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 and distributions 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.

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.

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.

Repurchase Agreements: The Fund may invest excess cash in repurchase agreements whereby the Fund purchases investments, which serve as collateral, with an agreement to resell such collateral to the seller at an agreed upon price at the maturity date of the repurchase agreement. Investments pledged as collateral for repurchase agreements are held in custody until maturity of the repurchase agreement. Provisions in the agreements require that the market value of the collateral is at least equal to the repurchase value in the event of default. In the event of default, the Fund has the right to liquidate the collateral and apply the proceeds in satisfaction of the obligation. Under

Thornburg Capital Management Fund^|September 30, 2020

certain circumstances, in the event of default or bankruptcy by the other party to the agreement, realization and/or retention of the collateral may be subject to legal proceedings.

Security Valuation: All investments in securities held by the Fund are valued as described in Note 3.

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 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. The values of these securities held at September 30, 2020 are detailed in the Schedule of Investments.

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.

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 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: Securities held with a maturity of less than 60 days are valued using the amortized cost method. The amortized cost method of valuation involves valuing a security at its cost initially and thereafter assuming a constant amortization to maturity of any discount or premium, regardless of the impact of fluctuating interest rates on the market value of the security. This method may result in periods during which value, as determined by amortized cost, is higher or lower than the price each Fund would receive if it sold the security. The market value of securities in the Fund can be expected to vary inversely with changes in prevailing interest rates.

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.

The amortized cost method of valuation may be used with respect to debt obligations with sixty days or less remaining to maturity unless the Advisor determines such method does not represent fair value. Investments in open-end U.S. mutual funds are valued at net asset value (“NAV”) each business day.

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 is stale, does not reflect material factors affecting the valuation of the investment, is significantly different than the value the Fund is likely to obtain if it sought a bid for the investment, or is otherwise unreliable, the Committee calculates a fair value for the obligation using an alternative method approved by the Audit Committee.

Thornburg Capital Management Fund^|September 30, 2020

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 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 is typically calculated by pricing service providers approved by the Audit Committee and are generally characterized as Level 2 within the valuation hierarchy.

The following table displays a summary of the fair value hierarchy measurements of the Fund’s investments as of September 30, 2020:

	TOTAL	LEVEL 1	LEVEL 2	LEVEL 3
Assets
Investments in Securities
Short-Term Investments	$ 1,756,608,949	$ 48,246	$ 1,756,560,703	$ —
Total Assets	$ 1,756,608,949	$ 48,246	$ 1,756,560,703	$—

NOTE 4 – INVESTMENT MANAGEMENT FEE AND OTHER TRANSACTIONS WITH AFFILIATES

Pursuant to an investment advisory agreement, the Advisor serves as the investment advisor and performs services for the Fund. The Fund does not pay an advisory fee to the Advisor under this agreement.

The Advisor provides certain administrative services to the Fund. No fees are charged for these services.

The Fund may purchase or sell securities from or to an affiliated fund, provided the affiliation is due solely to having a common investment advisor, common officers, or common trustees, and provided that all such transactions will comply with Rule 17a-7 under the 1940 Act. For the year ended September 30, 2020, the Fund had no such transactions with affiliated funds.

NOTE 5 – TAXES

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
