Important Update to the Fund

Effective March 23, 2026, the Fund’s name, principal investment strategies and benchmarks were changed.

The Fund offers both mutual fund share classes and an ETF class of shares. The ETF class shares are listed and traded on a national securities exchange and are not individually redeemable, unlike the mutual fund class shares. An investment in the ETF class shares is not an investment in a mutual fund, and an investment in the mutual fund class shares is not an investment in an ETF.

Use the share class drop-down above to switch between the ETF and Mutual Fund class shares.

Overview

Overview

Why Invest in This Fund?

  • Focused, diversified U.S. growth portfolio: Invests in high-quality companies with sustainable competitive advantages and durable growth prospects, primarily within large- and mid‑capitalization U.S. equities.
  • Rigorous bottom-up fundamental research: Focused on uncovering promising growth companies with sound business fundamentals that trade below our estimate of long‑term value.
  • Three-basket portfolio construction: Seeks to provide diversification, reduce volatility, and deliver superior risk‑adjusted performance over time through a balanced, high‑conviction approach.

Investment Objective

The Fund seeks long-term growth of capital by investing in equity securities selected for their growth potential.

Investment Approach

The Fund applies bottom-up fundamental research to identify U.S. companies with high-quality business models and durable growth prospects, primarily in large caps. Using a three-basket construction, we balance exposures across the growth spectrum to diversify and manage risk. The portfolio is high conviction yet diversified, generally holding 40–60 names, with discipline around position sizing and valuation monitoring.

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.

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.

As of March 23, 2026, the fund's primary benchmark changed from the Russell 2500 Growth Index to the Russell 1000 Growth Index.

Before March 23, 2026, the Fund was managed with different a different principal investment strategy under the name “Thornburg Small/Mid Cap Growth Fund” and may have achieved different performance results under its current principal investment strategy from the performance shown for periods before that date.

For ETF Class Shares:
Total returns are calculated quarterly using the daily 4:00pm net asset value (NAV). Distributions, if any, are assumed to be reinvested back into the fund on the pay date at the NAV on that date. Performance data quoted represents past performance and past performance is no guarantee of future results. Current performance may be lower or higher than quoted. The investment return and principal value of an investment will fluctuate so that an investor's shares, when sold or redeemed, are subject to market volatility. They may be worth more or less than their original cost. ETF class shares are bought and sold at market price (not NAV) and are not individually redeemed from the Fund. Brokerage commissions will reduce returns.

The inception date for the Fund's ETF Class is April 1, 2026. An investment in the Fund’s ETF Class shares is not an investment in a mutual fund.

Past performance does not guarantee future results.

Risk & Return Profile metrics are based on the I share class.

Due to the change in the Fund’s investment objective and benchmark effective March 23, 2026, the Risk & Return Profile shown above may not be representative of the Fund’s current risk and return characteristics.

For ETF Class Shares
The inception date for the Fund's ETF Class is April 1, 2026. The Risk & Return Profile metrics are therefore based on the Fund's Class I shares. The Fund's Class I shares are a mutual fund class of shares of the Fund. The Fund's ETF Class and mutual fund class shares, including the Class I shares, are invested in the same portfolio of securities. Unlike the Fund's mutual fund class shares, the Fund's ETF Class shares are listed and traded on a national securities exchange and are not individually redeemable. An investment in the Fund’s ETF Class shares is not an investment in a mutual fund.

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.

Please see our glossary for a definition of terms.

Thornburg mutual funds are distributed by Thornburg Securities LLC.

Thornburg Investment Management, Inc. mutual funds are sold through investment professionals including investment advisors, brokerage firms, bank trust departments, trust companies and certain other financial intermediaries. Thornburg Securities LLC (TSL) does not act as broker of record for investors.

For ETF Class Shares:
The Advisor and certain Portfolios have received an exemptive order from the Securities and Exchange Commission permitting these Portfolios to offer both a mutual fund share class and an exchange-traded share class that operates as an ETF. Under this structure, the ETF class shares are listed and traded on a national securities exchange and are generally bought and sold at market-determined prices, whereas the mutual fund share classes are purchased and redeemed at the Portfolio’s net asset value next determined after receipt of the order. Because all of the classes of a multi-class Portfolio are based on the same portfolio, transactions through one class could generate portfolio transaction costs and tax consequences for shareholders in other classes. In addition, shareholders of the mutual fund and ETF classes of a multi-class Portfolio will have differing shareholder rights with respect to exchange privileges, how shares are purchased and redeemed, the timing of dividend declarations and payments, and the timing and ability to automatically reinvest dividends. For additional information regarding these differences, please see the applicable multi-class Portfolio’s prospectus.

Each Fund’s ETF Class shares are listed and traded on a national securities exchange and, unlike the Fund's mutual fund class shares, are not individually redeemable. In addition to ETF Class shares, the Fund offers one or more classes of mutual fund shares. An investment in the Fund’s ETF Class shares is not an investment in a mutual fund.

The Fund's ETF Class shares are distributed by ALPS Distributors, Inc.

Tax efficiency benefits associated with ETF Class shares are not guaranteed and may vary based on market conditions, portfolio activity, and shareholder transactions.

The Fund is actively managed and does not seek to replicate the performance of a specified index.

Expenses differ between the Fund's ETF Class shares and mutual fund share classes.

Risks associated with investing in the Fund's ETF Class shares may include, but are not limited to: (1) Investment Adviser Risk, which is the risk that the Adviser’s investment decisions may not produce the intended results. (2) Derivatives Risk, as the Funds’ use of derivatives—including futures, options, swaps, and forward contracts—may expose them to risks related to the underlying instruments as well as additional risks such as counterparty default, liquidity constraints, valuation difficulties, and potential delays in closing positions.
