Dear Valued Shareholder,

I am writing to you regarding a very important matter affecting your investment in the Jackson Square

Partners Funds.A few weeks ago, you received proxy voting materials via email or mail. Our records indicate

that we have not yet received your important proxy vote.

After careful consideration, the Board of Trustees of the Funds’ Trust approved the reorganization of the

Jackson Square Large-Cap Growth Fund and the Jackson Square SMID-Cap Growth Fund with and into the

Spyglass Growth Fund. This transaction is subject to shareholder approval at a joint special meeting of

shareholders to be held on October 24, 2025. The investment objectives of the existing funds and the Spyglass

Growth Fund and the Acquiring Fund are identical. Each Fund invests primarily in common stocks of growth-

oriented companies.

Please take a moment to cast your proxy vote today.This is not just a procedural step, your vote ensures that

your interests are represented. The reorganization depends on shareholders responding to vote their shares.

For more information please, visit proxyonline.com/jacksonsquare/docs/2025mtg.pdf, or call the live

operator toll-free number listed below.

We very much appreciate your attention to this matter. Thank you in advance for casting your proxy vote.
