Supplement to Proxy Statement for the

Cerner Corporation 2021 Annual Shareholders' Meeting

At the 2021 Annual Shareholders Meeting of Cerner Corporation ("Cerner" or the "Company") to be held virtually on May 19, 2021 at 10:00 a.m. (CT), shareholders of the Company are being asked, among other things, to vote on a proposal to approve the compensation of Cerner's Named Executive Officers on a non-binding, advisory basis, as disclosed in Cerner's definitive proxy statement on Schedule 14A filed with the Securities and Exchange Commission on April 2, 2021 (the "Proxy Statement"). This Supplement to the Proxy Statement (this "Supplement") contains information to supplement "Proposal #3 Advisory Vote to Approve the Compensation for our Named Executive Officers" of the Proxy Statement. Cerner is providing this Supplement as additional context to help you evaluate the compensation provided to Mr. Peterzalek and Mr. Naughton in connection with their departures from the Company in the first quarter of 2021.

Each of the two departures from the Company were characterized as a termination by Cerner without "Cause" as defined in Mr. Peterzalek's and Mr. Naughton's Executive Severance Agreements, which have been in place since December 2017 and September 2017, respectively. Each of Mr. Peterzalek and Mr. Naughton received severance benefits as described in the Proxy Statement. In each case, those severance benefits were payable pursuant to the applicable terms of their respective Executive Severance Agreements for a termination by Cerner without "Cause." Each of them received similar treatment for their performance share units, with vesting at 100% of target.

The Board of Directors recommends that you vote IN FAVOR of the proposal to approve the compensation of Cerner's Named Executive Officers on a non-binding, advisory basis as disclosed in the Proxy Statement, and supplemented by this Supplement.
