Periods less than one year are not annualized.

Performance data shown represents past performance and is no guarantee of future results. Investment return and principal value will fluctuate so shares, when redeemed, may be worth more or less than their original cost. Current performance may be lower or higher than quoted.

The maximum sales charge for the equity funds' A shares is 4.50%. C shares include a 1% contingent deferred sales charge (CDSC) for the first year only. There is no up-front sales charge for class I or R shares.

Effective December 18, 2020, Thornburg Core Growth Fund's name changed to Thornburg Small/Mid Cap Growth Fund, and the Fund adopted a policy, under normal conditions, to invest at least 80% of its net assets in small- and mid-capitalization companies. As a result, the Fund's investment benchmark changed from the Russell 3000 Total Return Growth Index to the Russell 2500 Growth Index (Total Return).

Morningstar quartile ranking for Large Growth category is based on total returns before sales charges.

Prior to inception of I and R share classes, performance is hypothetical and was calculated from actual returns of an earlier share class adjusted for the expenses of the newer share class.

Share class inception dates: A and C shares, 27 Dec 2000; I shares, 3 Nov 2003; R3 shares 1 Jul 2003; R4, 1 Feb 2007; and R5 shares, 3 Oct 2005.

Important Information

Before investing, carefully consider the Fund's investment goals, risks, charges, and expenses. For a prospectus or summary prospectus containing this and other information, contact your financial advisor or visit thornburg.com. Read them carefully before investing.

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. Investments in the Fund are not FDIC insured, nor are they bank deposits or guaranteed by a bank or any other entity.

The performance of any index is not indicative of the performance of any particular investment. Unless otherwise noted, index returns reflect the reinvestment of income dividends and capital gains, if any, but do not reflect fees, brokerage commissions or other expenses of investing. Investors may not make direct investments into any index.

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

Funds invested in a limited number of holdings may expose an investor to greater volatility.

Class R shares are limited to retirement platforms only.

Class I shares may not be available to all investors. Minimum investments for the I share class may be higher than those for other classes.

There is no guarantee that the Fund will meet its investment objectives.

To determine a fund's Morningstar Rating™, funds and other managed products with at least a three-year history are ranked in their categories by their Morningstar Risk-Adjusted Return scores. The top 10% receive 5 stars; the next 22.5%, 4 stars; the middle 35%, 3 stars; the next 22.5%, 2 stars; and the bottom 10% receive 1 star. The Risk-Adjusted Return accounts for variation in a managed product's monthly excess performance (excluding sales charges), placing more emphasis on downward variations and rewarding consistent performance. Other share classes may have different performance characteristics.
