TABLE OF CONTENTS

INCORPORATION OF CERTAIN INFORMATION BY REFERENCE This prospectus supplement and the accompanying prospectus are part of the registration statement and do not contain all of the information included in the registration statement. Whenever a reference is made in this prospectus supplement or the accompanying prospectus to any contract or other document of The Cigna Group, the reference may not be complete and you should refer to the exhibits that are a part of the registration statement for a copy of the contract or document. The SEC allows us to “incorporate by reference” information we file with the SEC into this prospectus supplement and the accompanying prospectus, which means that we can disclose important information to you by referring you to another document filed separately with the SEC. The information incorporated by reference in this prospectus supplement or the accompanying prospectus is an important part of such document, and information that we will file later with the SEC will automatically update and supersede this information. This prospectus supplement incorporates by reference the documents set forth below that The Cigna Group has previously filed with the SEC and that are not delivered with this prospectus supplement. These documents contain important information about The Cigna Group and its financial condition. Since information that we file with the SEC in the future will update and supersede previously incorporated information, you should look at all of the SEC filings that we incorporate by reference to determine if any of the statements in this prospectus supplement or the accompanying prospectus or in any documents previously incorporated by reference have been modified or superseded.
