Dear Shareholder:

We have sent you several mailings concerning important proposals regarding your investments in American Beacon Funds. The Special Meeting for the funds had to be adjourned again to allow shareholders more time to vote on the proposals. The Special Meeting will reconvene in February 2024.

We are required to gather a specific number of votes to have a quorum for our upcoming Shareholder Meeting. Your vote allows us to reach that required quorum.

This letter was sent to you because you held shares in the fund(s) on the record date and we have not received your vote! Because your vote is critical, our outreach to you will continue until there is sufficient voting.

Please vote by one of these four options:

· Vote Online - Visit the website noted on the enclosed proxy card and follow the instructions.

· Vote by Mail - Mail your signed proxy card(s) in the postage-paid envelope.

· Vote by Phone - Call the toll-free number printed on the enclosed proxy card and follow the automated instructions. Available 7 days a week 24 hours a day.

· Speak with a Proxy Specialist - Call 1-866-434-5625 with any questions. Specialists can assist with voting. Available Mon-Fri from 9 a.m. – 11 p.m. ET and Sat from 12 p.m. – 6 p.m. ET

Dear Shareholder:

We’ve been trying to reach you regarding your investment in the above American Beacon Fund.

Thank you in advance for your assistance with this matter.

Sincerely,
