Pioneer Floating Rate Trust, a Delaware statutory trust (the “Fund”), is filing definitive additional materials contained in this Schedule 14A with the U.S. Securities and Exchange Commission (“SEC”) in connection with the Fund’s solicitation of proxies from its shareholders in connection with the matters to be considered at the Fund’s 2020 Annual Meeting of Shareholders and at any and all adjournments, postponements, continuations, and reschedulings thereof (the “2020 Annual Meeting”). In connection with its 2020 Annual Meeting, the Fund filed a definitive proxy statement and a definitive form of WHITE proxy card with the SEC on August 3, 2020.

Letter to Shareholders First Made Available on August 26, 2020

Attached hereto is a letter dated August 26, 2020 that the Fund is sending to shareholders in connection with the 2020 Annual Meeting. As previously disclosed, Saba Capital Management, L.P. (“Saba”) is seeking to elect three candidates to the Fund’s Board of Trustees (the “Board”) at the 2020 Annual Meeting in opposition to the three highly qualified and very experienced nominees recommended by the Board, all of whom are current members of the Board. Saba has also disclosed it intends to present a shareholder proposal at the 2020 Annual Meeting to terminate the Fund’s investment advisory agreement with Amundi Pioneer Asset Management, Inc. In its letter, the Fund reminds shareholders to vote on the WHITE proxy card “FOR ALL” of the Board’s nominees and “AGAINST” Saba’s proposal to terminate the Fund’s investment advisory agreement with Amundi Pioneer Asset Management, Inc. The Fund’s letter to shareholders is being filed herewith because it may be deemed to be solicitation material in connection with the Fund’s solicitation of proxies to be used at the 2020 Annual Meeting.

The Fund’s trustees, executive officers, and certain persons associated with the Fund’s investment adviser and its parent company are deemed participants in the solicitation of proxies from the Fund’s shareholders in connection with the matters to be considered at the 2020 Annual Meeting of Shareholders.

Information regarding the names of the Fund’s trustees, executive officers, and certain persons associated with the Fund’s investment adviser and its parent company and their respective direct or indirect interests in the Fund by security holdings or otherwise can be found in such such definitive proxy statement, including the schedules and appendices thereto. INVESTORS AND SHAREHOLDERS ARE STRONGLY ENCOURAGED TO READ ANY SUCH PROXY STATEMENT AND THE ACCOMPANYING WHITE PROXY CARD AND OTHER DOCUMENTS FILED BY THE FUND WITH THE SEC CAREFULLY AND IN THEIR ENTIRETY WHEN THEY BECOME AVAILABLE AS THEY WILL CONTAIN IMPORTANT INFORMATION.

Dear Valued Shareholder:

We recently sent you proxy materials with a WHITE proxy card in connection with the upcoming 2020 Annual Meeting of Shareholders of Pioneer Floating Rate Trust (the “Fund”) to be held on September 16, 2020. As you may be aware, an activist investor, Saba Capital Management, L.P. (“Saba”) is planning a proxy contest at our Annual Meeting and has likely also sent you its proxy materials and a gold proxy card.

Your vote is important, no matter how many shares you own. We implore shareholders to only vote on each and every WHITE proxy card we send you in accordance with the unanimous recommendations of your Board — “FOR ALL” of the Board’s highly qualified and very experienced nominees, all of whom, are current members of your Board, — and “AGAINST” Saba’s proposal to terminate the Fund’s investment advisory agreement with Amundi Pioneer Asset Management, Inc., a proposal that we believe is potentially devastating since, if approved, it could leave your Fund without a Manager to run the day to day operations of the Fund:

		FOR ALL	WITHHOLD ALL	FOR ALL EXCEPT
Proposal 1:	To elect three Class II Trustees: 1) Diane P. Durnin 2) Benjamin M. Friedman 3) Kenneth J. Taubes
		FOR	AGAINST	ABSTAIN
Proposal 2:	If properly presented, to vote upon a shareholder proposal from Saba Capital Master Fund, Ltd. to terminate the Fund’s investment advisory agreement with Amundi Pioneer Asset Management, Inc.

The Fund’s proxy statement, which describes these proposals and your Board’s unanimous voting recommendations in more detail, is available online at www.OkapiVote.com/PHD

Please do not return or otherwise vote any other proxy card or voting instruction form sent to you by Saba—even as a protest vote against Saba as this may cancel your prior vote on the Board’s WHITE proxy card.

In order for your vote to be represented, we must receive your voting instructions. For your convenience, please use any of the following methods to submit your vote:

1. By Internet

Follow the simple instructions on the enclosed WHITE proxy card.

2. By Touchtone

3. By Mail
