NOTICE OF CHANGE OF LOCATION

OF ANNUAL MEETING OF STOCKHOLDERS TO BE HELD ON APRIL 21, 2020

To Our Stockholders:

In response to continued public health concerns about in-person gatherings given the COVID-19 outbreak, NOTICE IS HEREBY GIVEN that the location of the Annual Meeting of Stockholders of Whirlpool Corporation has been changed. As previously announced, the Annual Meeting will be held on Tuesday, April 21, 2020 at 8:00 a.m. Central Time. However, the Annual Meeting will no longer be held at 331 N. LaSalle, Chicago, Illinois, but rather will be held in a virtual-only format via the internet. You will not be able to attend the Annual Meeting in person.

As described in the proxy materials for the Annual Meeting previously distributed, you are eligible to attend and vote at the Annual Meeting if you were a stockholder of record as of the close of business on February 24, 2020, the record date, or if you hold a legal proxy for the meeting provided by your bank, broker or nominee. To be admitted to the Annual Meeting and access the stockholder list, go to www.virtualshareholdermeeting.com/WHR2020 and enter the control number found on your proxy card, voting instruction form or notice you previously received. You may vote during the Annual Meeting by following the instructions available on the meeting website during the meeting. For 401(k) plan holders, if you do not provide voting instructions to Vanguard by 11:59 p.m. Eastern time on April 16, 2020, the Whirlpool shares in your plan account will be voted by Vanguard in the same proportion as the shares held by Vanguard for which voting instructions have been received from other participants in the plan. If you are not eligible to participate in the meeting, you may listen to a webcast of the meeting by visiting www.virtualshareholdermeeting.com/WHR2020.

The proxy card included with the materials previously distributed will not be updated to reflect the change in format and may continue to be used to vote your shares in connection with the Annual Meeting. Whether or not you plan to attend the Annual Meeting, please vote and submit your proxy in advance of the meeting using one of the methods described in the proxy materials.

On behalf of our Board of Directors, thank you for your continued support.
