To the Shareholders of PotlatchDeltic Corporation,

Due to the emerging public health impact of the novel coronavirus (COVID-19) pandemic, Governor Inslee’s extension of the Stay Home order for the State of Washington through May 4, 2020, and to support the health and well-being of our employees and shareholders, NOTICE IS HEREBY GIVEN that the format of the Annual Meeting of the Company has changed. As previously disclosed, the Annual Meeting will be held on Monday, May 4, 2020 at 9:00 a.m. Pacific Daylight Time.  For the foregoing reasons, the Annual Meeting will now be held in a virtual meeting format only. You will not be able to attend the Annual Meeting in person.
