PGIM JENNISON 20/20 FOCUS FUND

a series of The Prudential Investment Portfolios 18

655 Broad Street

Newark, NJ 07102

July 26, 2021

Dear Shareholder:

As you are likely aware, the PGIM Jennison 20/20 Focus Fund (the "20/20 Focus Fund") is in the process of holding a Special Meeting of Shareholders (the "Meeting"). The original Meeting was scheduled and held on June 15, 2021, however there was not enough 20/20 Focus Fund shareholder participation in order to approve the proposal. Therefore, the Meeting was adjourned to Tuesday, August 10, 2021 at 1:00 p.m. Eastern time in order to gather further participation.

PGIM Investments LLC, the 2020 Focus Fund's investment adviser, recommended, and the 20/20 Focus Fund's Board of Trustees unanimously approved, a proposal to merge the Fund with and into the PGIM Jennison Focused Growth Fund (the "Acquiring Fund"), a series of Prudential Investment Portfolios 3.

WHAT ARE THE POTENTIAL BENEFITS OF THE PROPOSED MERGER TO SHAREHOLDERS OF THE 20/20 FOCUS FUND? The merger will offer 20/20 Focus Fund shareholders certain potential benefits, including:

BETTER PERFORMANCE. The Focused Growth Fund's investment performance has been stronger than that of the 20/20 Focus Fund as of the year to date, and one-, three-, five-, and ten-year periods ended September 30, 2020 for the same periods.

REDUCED EXPENSES. The merger is expected to result in reduced gross and net expenses for the 20/20 Focus Fund shareholders.

ECONOMIES OF SCALE. Shareholders of each Fund could benefit from long-term economies of scale that may result from the merger.

SIMILAR INVESTMENT STRATEGIES. Both Funds are equity funds with identical investment objectives and similar investment strategies and investment restrictions;

WHAT DO WE NEED FROM YOU?

While the merger offers many potential benefits to 20/20 Focus Fund shareholders, the merger cannot be implemented without obtaining the required authorization from 20/20 Focus Fund shareholders. Please also note that the 20/20 Focus Fund's shareholder base is made up of thousands of investors just like yourself, which makes your vote even more important no matter how many shares you own. Accordingly, your vote is critical to the approval of this proposal.
