American Beacon Advisors and DoubleLine Capital Further Their Partnership to Create Greater Access to DoubleLine’s Investment Acumen for the Wealth Channel

American Beacon acquires DoubleLine Select Income Fund; announces merger of DoubleLine Floating Rate Fund with the American Beacon DoubleLine Floating Rate Fund

DoubleLine will sub-advise both Funds

IRVING, Texas–(BUSINESS WIRE)–American Beacon Advisors, Inc. (“American Beacon”), an experienced provider of investment advisory services to institutional and retail markets, announced today that it has expanded the firm’s ongoing partnership with leading fixed income-focused asset manager DoubleLine Capital (“DoubleLine”).

American Beacon has assumed management of the DoubleLine Select Income Fund, renamed as the American Beacon DoubleLine Select Income Fund (Y Class: BILDX; R6 Class: BILRX; Investor Class: BILTX). The acquisition of the Fund brings a top-performing core bond strategy to the American Beacon platform. The Fund holds a 5-Star Morningstar rating for its Y Class. It offers compelling diversification benefits due to its low correlation to the Bloomberg U.S. Aggregate Bond Index while seeking unique inefficiencies in corporate and securitized debt.

Additionally, American Beacon merged the DoubleLine Floating Rate Fund and the American Beacon DoubleLine Floating Rate Fund. The newly merged fund, now the American Beacon DoubleLine Floating Rate Fund (A Class: ADLAX; C Class: ADLCX; Y Class: ADLYX; R5 Class: ADLIX; Investor Class: ADLPX), will adopt DoubleLine’s historical performance and tickers, as well as a new CUSIP.

Greg Stumm, President and CEO of American Beacon Partners, said: “At the core of our mission is a focus on partnering with best-in-class managers to bring their strategies to a broader universe of investors, particularly in the wealth channel. When one thinks of leaders across the fixed income universe, there are few that can compete with the acumen, expertise and track record of the DoubleLine team. In making the changes we are announcing today, we’re further enhancing a fund lineup designed to provide opportunities for attractive yields, diversification, and opportunistic credit exposures. Being truly open architecture in our approach allows us to constantly strive to build a complete platform of solutions, and we’re thrilled to be announcing these updates today.”

Andrew Hsu, Portfolio Manager of the Select Income Fund at DoubleLine, said: “American Beacon has been an excellent strategic partner for DoubleLine and these transactions strengthen our partnership in a meaningful way. The scale and reach of the American Beacon platform and their approach to distribution will allow us to remain fully focused on maintaining our disciplined investment process and long-term viewpoint as we navigate the fixed income universe.”

Both transactions were effective after the close on February 20, 2026, and are part of American Beacon’s strategy to continually advance its portfolio and platform for investors by partnering with industry leading investment managers.

Important Information: Past performance is no guarantee of future results. All investing involves risk, including possible loss of principal.

American Beacon DoubleLine Select Income Fund: The use of fixed-income securities entails interest rate and credit risks. Interest rate risk is the risk that debt securities will decrease in value with increases in market interest rates. Credit risk is the risk that a debt issuer will fail to make timely payment of interest or principal; the decline in an issuer’s credit rating can cause the price of its debt securities to go down. In addition, loans are subject to the risk that the Fund may not be able to obtain the collateral securing the loan in a timely manner, and the value of the collateral may not cover the amount owed on the loan. Concentration in infrastructure investments makes the Fund dependent upon the successful development, construction, maintenance, renovation, enhancement or operation of infrastructure-related projects, which may be negatively affected by economic, regulatory, political, legal, demographic, environmental, and other developments. Investments in high-yield securities (commonly referred to as “junk bonds”), including loans, CLOs, restricted securities and floating-rate securities, are subject to greater levels of credit, interest rate, market and liquidity risks than investment-grade securities. Investing in foreign and emerging markets may involve heightened risk due to currency fluctuations and economic and political risks. Derivative instruments may be highly sensitive to market factors, have less liquidity than other investments and involve the potential for losses to exceed the amount invested. Because the Fund may invest in fewer issuers than a more diversified portfolio, the fluctuating value of a single holding may have a greater effect on the value of the Fund.

For each fund with at least a three-year history, Morningstar calculates a Morningstar Rating based on a Morningstar Risk-Adjusted Return measure that accounts for variation in a fund’s monthly performance (including the effects of sales charges, loads and redemption fees), placing more emphasis on downward variations and rewarding consistent performance. The top 10% of funds in each category receive 5 stars, the next 22.5% receive 4 stars, the next 35% receive 3 stars, the next 22.5% receive 2 stars and the bottom 10% receive 1 star. (Each share class is counted as a fraction of one fund within the scale and rated separately, which may cause slight variations in the distribution percentages.)

The Overall Morningstar Rating for a fund is derived from a weighted average of performance figures associated with its three-, five- and 10-year (if applicable) Morningstar Rating metrics. In the U.S.-domiciled Bank Loan category, the American Beacon DoubleLine Select Income Fund (Y Class) was rated 5 stars out of 414 funds overall. The Fund was rated 5 stars out of 414 funds and 5 stars out of 374 funds for the three- and five-year periods, respectively. Past performance is no guarantee of future results.
