NOTICE OF CHANGE OF LOCATION
OF ANNUAL
MEETING OF STOCKHOLDERS
TO BE HELD ON THURSDAY, OCTOBER 7, 2021
TO RPM INTERNATIONAL STOCKHOLDERS:
In light of the continuing impact of Covid-19 and its variants, and to maintain the health and safety of our investors and employees, NOTICE IS HEREBY GIVEN that the location of the Annual Meeting has been changed to be held in a virtual meeting format
only. You will not be able to attend the Annual Meeting in person. As previously announced, the Annual Meeting will be held on Thursday, October 7, 2021 at 2:00 p.m. Eastern Daylight Time.
If you were a stockholder of the Company as of the close of business on the record date of August 13, 2021, you are entitled to participate in the Annual Meeting,
vote your shares and ask questions during the Annual Meeting, which will be webcast live and can be accessed at www.rpminc.com or www.virtualshareholdermeeting.com/RPM2021. A replay will be available until October 6, 2022.
To participate in the Annual Meeting as a stockholder, you will need
the 16-digit control number included on your proxy card. Guests without a control number can attend the Annual Meeting in listen-only mode but will not have the
ability to ask questions or vote.
As a stockholder, regardless of your plans to attend the virtual-only Annual Meeting, you are encouraged to vote and submit your
proxy in advance of the Annual Meeting using one of the methods described in the Proxy Statement. This will ensure that your vote will be counted if you later decide not to attend the Annual Meeting. The proxy card included with your Proxy Statement
will not be updated to reflect the change in location and may continue to be used to vote your shares in connection with the Annual Meeting. You may vote during the Annual Meeting by following the instructions available on the Annual Meeting
website. For assistance leading up the Annual Meeting, call Innisfree M&A Incorporated at (888) 750-5834. A support line will be available on the Annual Meeting website shortly prior to, and
during, the Annual Meeting to assist stockholders with any technical difficulties they may have accessing or hearing the virtual Annual Meeting.
If you wish to
submit a question, as a stockholder you may do so during the virtual Annual Meeting by typing your question in the Ask a Question field and clicking Submit. If any questions pertinent to Company matters cannot be answered
during the Annual Meeting due to time constraints, the Company will make an effort to address those questions in the Frequently Asked Questions section of the Companys website at www.rpminc.com. This will be done
as soon as reasonably practicable after the Annual Meeting and will remain available for one week after posting.
By Order of the Board of Directors.
