The decision to split the stock was made by Cerner Corporation’s Board of Directors, based on a desire to make the company’s stock more accessible to a broader range of investors.

• The Record Date – June 17, 2013 - determines which shareholders are entitled to receive additional shares due to the split. If you own common shares on the record date, your shares will be subject to the stock split.
• Distribution or Payable Date – June 28, 2013 - date when, as of close of trading, Computershare, Cerner Corporation’s transfer agent, will adjust stockholders’ holdings to reflect the stock split.
• Mailing Date – Week of July 1 - time period when shareholders of record are mailed notification of the shares subject to split.
• Ex-split Date – July 1, 2013 - date when Cerner Corporation common shares will trade on NASDAQ at the new split-adjusted price.

A. This is the sixth time the company has split the stock since Cerner Corporation went public in December 1986. Below are the dates of the stock splits (dates reflect first day of trading at split-adjusted price).

• May 12, 1992
• March 1, 1993
• August 7, 1995

• June 27, 2011

If you hold shares in a brokerage account, the additional shares will automatically be deposited to your brokerage account. Registered shareholders will not receive a stock certificate. Instead, if you hold paper certificates now, the additional shares you receive as a result of the stock split are being distributed through the Direct Registration System (DRS). This means that you have full ownership of your shares without the responsibility of holding the actual certificates. A Direct Registration Transaction Advice (DRTA) will be mailed to you by Computershare, our transfer agent, and is your confirmation; it indicates the number of additional shares you own as a result of the split. Keep it with your existing stock certificates and other important documents as a record of your ownership.

Existing stock certificates are still valid. Do not destroy them. You may deposit your existing certificate(s) to a DRS account at Computershare or in a brokerage account, or you may continue to physically hold them and be responsible for their safekeeping.
