Dear Fellow Stockholder:

We previously sent you proxy materials for the important Special Meeting of Stockholders of Exact Sciences Corporation to be held on February 20, 2026, in connection with the proposed merger with Abbott (the "Merger").

**Your Board of Directors unanimously recommends that you vote FOR the Merger and related proposals.** 

Your vote is very important. Please note that failing to vote will have the same effect as a vote ***against*** the Merger. **If you have not already done so, please vote TODAY *via* the Internet, by telephone, or by completing, dating and signing the enclosed proxy card or voting instruction form and returning it in the postage-prepaid envelope provided.** 

On behalf of Exact Sciences Corporation, thank you for your support.

Sincerely,
