Supplement to Proxy Statement for the
Cerner Corporation 2022 Annual Shareholders' Meeting

At the 2022 Annual Shareholders' Meeting of Cerner Corporation ("Cerner" or the "Company") to be held virtually on May 26, 2022 at 10:00 a.m. (CT), shareholders of the Company are being asked, among other things, to vote on a proposal to approve an amendment and restatement of the Cerner Corporation 2011 Omnibus Equity Incentive Plan to increase the number of authorized shares and extend the plan's term, as disclosed in Cerner's definitive proxy statement on Schedule 14A filed with the Securities and Exchange Commission on April 11, 2022 (the "Proxy Statement"). This Supplement to the Proxy Statement (this "Supplement") is being provided to supplement information provided under "Proposal #5 Amendment and Restatement of the 2011 Omnibus Equity Incentive Plan" of the Proxy Statement.

The section entitled "Vote Required" in Proposal #5 is revised to state that the vote required for approval of the proposal is set forth in the Proxy Statement under QUESTIONS AND ANSWERS ABOUT THE ANNUAL MEETING AND VOTING - What vote is required? As discussed in the response to that question, (a) the affirmative vote of a majority of the shares of Cerner Common Stock present in person or represented by proxy and entitled to vote at the annual meeting is required for approval of Proposal #5, and (b) abstentions and broker non-votes are considered to be "present" and "entitled to" vote at the meeting with respect to Proposal #5, and as a result, abstentions and broker non-votes will have the same effect as a vote "Against" Proposal #5.

Cerner's Board of Directors recommends a vote "FOR" the amendment and restatement of the Cerner Corporation 2011 Omnibus Equity Incentive Plan as disclosed in the Proxy Statement, and supplemented by this Supplement.

Except as specifically supplemented by the information contained herein, all information set forth in the Proxy Statement remains unchanged. From and after the date of this Supplement, all references to the "Proxy Statement" are to the Proxy Statement as supplemented hereby. The Proxy Statement contains important information and this Supplement should be read in conjunction with the Proxy Statement.
