IMPORTANT UPDATE REGARDING INVESCO GOLD & PRECIOUS METALS FUND 

SPECIAL MEETING OF SHAREHOLDERS 

Change from In-Person Special Meeting of Shareholders to Virtual Special Meeting of Shareholders on April 24, 2020 at 1:00 p.m. (Central Time) 

Due to the potential adverse public health impact of the coronavirus outbreak (COVID-19), the location and format of the April 24, 2020 Special Meeting of Shareholders have been changed.   

The Special Meeting of Shareholders will be held on the same date and time but will be held over the Internet in a virtual meeting format only. You will not be able to attend the Special Meeting in person.  The proxy card included with the proxy materials previously distributed will not be updated to reflect the change in location and format.  It may continue to be used to vote your shares in connection with the Special Meeting.  We encourage you to cast your vote prior to the meeting.  

Accessing the Virtual Meeting – To access the virtual meeting, enter the following Virtual Shareholder Meeting link, www.meetingcenter.io/270913681.  To log-in to the virtual meeting you have two options: you can join as a “Guest” (Non-Shareholder) or you can join as a “Shareholder”.  

· “Guest” (Non-Shareholder) Option – If you join as a “Guest”, you will need to provide the following password: INV2020.  You will also need to provide your name and email address when you enter.   However, you will be unable to vote your shares or ask questions at the meeting.   

· “Shareholder” Option – If you join as a “Shareholder”, you will need to provide the following password: INV2020.  You will also need to provide the control number found on your proxy card or notice, or on the email you previously received. If you do not have your control number, you may attend the meeting as a “Guest” but you will be unable to vote your shares or ask questions at the meeting.   

Shareholders of record as of the close of business on January 27, 2020 should have received the control number on their proxy card or notice, or on the email you previously received. 

If you are not a shareholder of record but hold your shares through an intermediary, such as a bank or broker, you must register in advance to attend the Virtual Special Meeting. To register you must submit proof of your proxy power (legal proxy) reflecting your Invesco holdings, along with your name and email address, to Computershare Fund Services, as set forth below.
