Factors Affecting Performance [Text Block]

How did the Fund perform and what affected its performance?

The A Class of the Fund returned 3.19% (with sales charges) and 5.86% (without sales charges) for the twelve months ended March 31, 2026, compared to the Bloomberg US Aggregate Bond Index return of 4.35% and the S&P UBS Leveraged Loan Index return of 4.79%.

For the 12-month period ended March 31, 2026, the American Beacon DoubleLine Floating Rate Fund’s share classes generally outperformed the Bloomberg US Aggregate Bond Index and the S&P UBS Leveraged Loan Index.
The period featured several episodes of macroeconomic volatility and included three policy rate cuts from the Federal Reserve. While rate cuts reduced the Fund’s interest income, due to its floating-rate nature, longer-term interest rates rose and adversely impacted longer-term bonds where the Fund did not have exposure.
The largest contributors to Fund performance were loans within the healthcare sector, which performed well despite market volatility. The Fund also benefited from its higher average credit quality as lower quality loans underperformed across most sectors. The largest detractors from Fund performance were holdings in professional services and software-related entities that were adversely impacted by advancements in artificial intelligence, although the Fund was underweighted in those entities compared to its benchmark.

Material Fund Changes

This is a summary of certain changes to the Fund since February 20, 2026. For more complete information, you may review the Fund's next prospectus, which we expect to be available by August 1, 2026 at www.americanbeaconfunds.com/fund-resources/ or upon request at 800-658-5811.

The American Beacon DoubleLine Floating Rate Fund (“Acquiring Fund”) acquired the DoubleLine Floating Rate Fund, a series of DoubleLine Funds Trust (“Acquired Fund”), in a reorganization that closed on February 20, 2026. Shareholders of the Acquired Fund became shareholders of the Acquiring Fund. Since the Acquiring Fund had essentially identical investment objectives, substantially similar principal investment strategies and policies/restrictions and engaged the same investment adviser as the Acquired Fund, the Acquiring Fund adopted the prior performance and financial history of the Acquired Fund.

On August 25, 2025, the Board of Trustees approved the adoption of the American Beacon DoubleLine Floating Rate Fund (“the Fund”) by the American Beacon Funds and the change of the Fund’s fiscal year end to August 31. As a result, the Fund will have an audit as of March 31, 2026, a transition fiscal reporting period from April 1, 2026 through August 31, 2026, and its first full fiscal year reporting period will cover September 1, 2026 through August 31, 2027.

Factors Affecting Performance [Text Block]

How did the Fund perform and what affected its performance?

The C Class of the Fund returned 4.72% (with sales charges) and 5.72% (without sales charges) for the twelve months ended March 31, 2026, compared to the Bloomberg US Aggregate Bond Index return of 4.35% and the S&P UBS Leveraged Loan Index return of 4.79%.

For the 12-month period ended March 31, 2026, the American Beacon DoubleLine Floating Rate Fund’s share classes generally outperformed the Bloomberg US Aggregate Bond Index and the S&P UBS Leveraged Loan Index.
The period featured several episodes of macroeconomic volatility and included three policy rate cuts from the Federal Reserve.

The largest contributors to Fund performance were loans within the healthcare sector, which performed well despite market volatility. The Fund also benefited from its higher average credit quality as lower quality loans underperformed across most sectors. The largest detractors from Fund performance were holdings in professional services and software-related entities that were adversely impacted by advancements in artificial intelligence, although the Fund was underweighted in those entities compared to its benchmark.

Factors Affecting Performance [Text Block]

How did the Fund perform and what affected its performance?

The Investor Class of the Fund returned 5.85% for the twelve months ended March 31, 2026, compared to the Bloomberg US Aggregate Bond Index return of 4.35% and the S&P UBS Leveraged Loan Index return of 4.79%.

For the 12-month period ended March 31, 2026, the American Beacon DoubleLine Floating Rate Fund’s share classes generally outperformed the Bloomberg US Aggregate Bond Index and the S&P UBS Leveraged Loan Index.
The period featured several episodes of macroeconomic volatility and included three policy rate cuts from the Federal Reserve. While rate cuts reduced the Fund’s interest income, due to its floating-rate nature, longer-term interest rates rose and adversely impacted longer-term bonds where the Fund did not have exposure.
The largest contributors to Fund performance were loans within the healthcare sector, which performed well despite market volatility. The Fund also benefited from its higher average credit quality as lower quality loans underperformed across most sectors. The largest detractors from Fund performance were holdings in professional services and software-related entities that were adversely impacted by advancements in artificial intelligence, although the Fund was underweighted in those entities compared to its benchmark.

Factors Affecting Performance [Text Block]

How did the Fund perform and what affected its performance?

The R5 Class of the Fund returned 6.10% for the twelve months ended March 31, 2026, compared to the Bloomberg US Aggregate Bond Index return of 4.35% and the S&P UBS Leveraged Loan Index return of 4.79%.

For the 12-month period ended March 31, 2026, the American Beacon DoubleLine Floating Rate Fund’s share classes generally outperformed the Bloomberg US Aggregate Bond Index and the S&P UBS Leveraged Loan Index.
The period featured several episodes of macroeconomic volatility and included three policy rate cuts from the Federal Reserve. While rate cuts reduced the Fund’s interest income, due to its floating-rate nature, longer-term interest rates rose and adversely impacted longer-term bonds where the Fund did not have exposure.
The largest contributors to Fund performance were loans within the healthcare sector, which performed well despite market volatility. The Fund also benefited from its higher average credit quality as lower quality loans underperformed across most sectors. The largest detractors from Fund performance were holdings in professional services and software-related entities that were adversely impacted by advancements in artificial intelligence, although the Fund was underweighted in those entities compared to its benchmark.

The largest detractors from Fund performance were holdings in professional services and software-related entities that were adversely impacted by advancements in artificial intelligence, although the Fund was underweighted in those entities compared to its benchmark.

Factors Affecting Performance [Text Block]

How did the Fund perform and what affected its performance?

The Investor Class of the Fund returned 4.70% for the twelve months ended March 31, 2026, compared to the Bloomberg US Aggregate Bond Index return of 4.35%.

For the 12-month period ended March 31, 2026, the American Beacon DoubleLine Select Income Fund outperformed the Bloomberg US Aggregate Bond Index return of 4.35%.
This period featured several episodes of volatility in the markets but also included three policy rate cuts from the Federal Reserve, which allowed intermediate and short-term fixed income assets with less interest rate sensitivity to perform well.
The largest contributor to Fund performance was its exposure to data center asset-backed securities, as these investments became more attractive during the period.
Railcar asset-based securities detracted from Fund performance due to disruptions in global transportation volumes.

Material Fund Changes

The American Beacon DoubleLine Select Income Fund ("Acquiring Fund") acquired the DoubleLine Select Income Fund (formerly known as the DoubleLine Infrastructure Income Fund), a series of DoubleLine Funds Trust ("Acquired Fund"), in a reorganization that closed on February 20, 2026. Shareholders of the Acquired Fund became shareholders of the Acquiring Fund. Since the Acquired Fund had an identical investment objective and substantially similar principal investment strategies and policies/restrictions as the Acquiring Fund, the Acquiring Fund has adopted the prior performance and financial history of the Acquired Fund.

On August 25, 2025, the Board of Trustees approved the adoption of the American Beacon DoubleLine Select Income Fund (“the Fund”) by the American Beacon Funds and the change of the Fund’s fiscal year end to August 31. As a result, the Fund will have an audit as of March 31, 2026, a transition fiscal reporting period from April 1, 2026 through August 31, 2026, and its first full fiscal year reporting period will cover September 1, 2026 through August 31, 2027.

Factors Affecting Performance [Text Block]

How did the Fund perform and what affected its performance?

The R6 Class of the Fund returned 4.94% for the twelve months ended March 31, 2026, compared to the Bloomberg US Aggregate Bond Index return of 4.35%.

For the 12-month period ended March 31, 2026, the American Beacon DoubleLine Select Income Fund outperformed the Bloomberg US Aggregate Bond Index return of 4.35%.
This period featured several episodes of volatility in the markets but also included three policy rate cuts from the Federal Reserve, which allowed intermediate and short-term fixed income assets with less interest rate sensitivity to perform well.
The largest contributor to Fund performance was its exposure to data center asset-backed securities, as these investments became more attractive during the period.
Railcar asset-based securities detracted from Fund performance due to disruptions in global transportation volumes.

The largest contributor to Fund performance was its exposure to data center asset-backed securities, as these investments became more attractive during the period.
Railcar asset-based securities detracted from Fund performance due to disruptions in global transportation volumes.
