Overview

Why Invest in This ETF?

  • Enhanced Income and Return Potential — Seeks attractive income and long-term capital appreciation through a flexible, multi-sector fixed-income strategy designed to outperform traditional core bonds with only modestly higher risk.
  • Dynamic and Flexible Management — Actively invests across sectors, geographies, credit qualities, and maturities, with the ability to adjust allocations to capitalize on the best relative value opportunities.
  • Expertise with Downside Awareness — Managed by Thornburg’s experienced Global Fixed Income team, the ETF combines an opportunistic approach with a focus on mitigating risk in an effort to deliver consistent performance in diverse market conditions.

Investment Objective

The Thornburg Multi Sector Bond ETF (the “ETF”) seeks total return, consisting of income and capital appreciation. The Fund’s investment objective may be changed without shareholder approval.

Investment Approach

This ETF offers income and long-term capital appreciation with active management designed to adapt to changing markets. Investors can expect a meaningful focus on high-yield opportunities with the flexibility to adjust allocations based on relative value views to help drive income and return potential.

Periods less than one year are not annualized.

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 shares are bought and sold at market price (not NAV) and are not individually redeemed from the Fund. Brokerage commissions will reduce returns.

Holdings within the Geography breakdown are classified by country of risk as determined by MSCI and Bloomberg.

Portfolio holdings are subject to change daily.

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. Credit quality ratings use the highest rating available from either S&P Global Ratings or Moody's Investors Service. Unrated securities are evaluated by the firm using available data and their own analysis that may be similar to that of a nationally recognized rating agency; however, such determination is not equivalent to a national agency credit rating. "NR" = Not Rated.

Weights are percentages of the total portfolio unless otherwise noted.

May not add up to 100% due to rounding.

Short-Term Investments, Other Assets & Liabilities includes cash, short-term securities, other assets less liabilities, accruals, derivatives and forwards. It may also include investments in money market or similar funds managed by Thornburg that are not offered to the public.

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.

Thornburg ETFs are actively managed and do not seek to replicate the performance of a specified index. To determine whether to buy or sell a security, the portfolio managers consider, among other things, various fund requirements and standards, along with economic conditions, alternative investments, interest rates and various credit metrics. If the portfolio manager considerations are inaccurate or misapplied, the fund’s performance may suffer.

Please see our glossary for a definition of terms.

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.

Risks associated with investing in Thornburg ETFs may include: (1) Investment Adviser Risk. (2) New and Smaller Sized Fund Risk. The Fund is new, lacks operating history, may face challenges in implementing its strategies, attracting sufficient assets, or achieving economies of scale, and similar ETFs often experience lower trading volumes, wider bid/ask spreads, and potential liquidation risks without shareholder approval. (3) Derivatives Risk. The Fund's use of derivatives, such as futures, options, swaps, and forward contracts, carries risks tied to the underlying assets as well as additional risks, including counterparty default, liquidity challenges, valuation difficulties, and potential delays in closing positions.

Additional risks associated with investing in TPLS, TMB and THOR may include: (1) Credit Risk. If obligations held by the Fund are downgraded by ratings agencies or go into default, or if management action, legislation or other government action reduces the ability of issuers to pay principal and interest when due, the value of those obligations and the Fund’s investment may decline. (2) High Yield Risk. Debt obligations that are rated below investment grade and unrated obligations of similar credit quality (commonly referred to as “junk” or “high yield” bonds) may have a substantial risk of loss. (3) Interest Rate Risk. When interest rates increase, the value of the Fund’s investments may decline and the Fund’s share value may be reduced. When interest rates decrease, the Fund’s dividends may decline. (4) Market and Economic Risk. The Fund's investments, particularly in lower-rated or unrated debt obligations like high-yield bonds, are more susceptible to value declines due to economic and market conditions, poor economic growth, and issuer-specific, political, economic, or legal developments.

Exchange Traded Funds (ETF) are bought and sold through exchange trading at market price (not NAV), and are not individually redeemed from the fund. Shares may trade at a premium or discount to their NAV in the secondary market. Brokerage commissions will reduce returns.

Thornburg ETFs are distributed by ALPS Distributors, Inc.
