SEC Form S-3ASR filed by The Cigna Group

The Cigna Group may offer and sell the securities listed above from time to time in one or more classes or series and in amounts, at prices and on terms that we may determine at the time of the offering. We will provide the specific terms of the securities in supplements to this prospectus.

The debt securities, preferred stock, warrants and purchase contracts may be convertible into or exercisable or exchangeable for common or preferred stock or other securities of the Company or debt or equity securities of one or more other entities. These securities may also be sold by one or more selling security holders to be named in a prospectus supplement. You should read this prospectus and any related prospectus supplement carefully before you invest in our securities.

Our common stock is listed on the New York Stock Exchange (the “NYSE”) under the symbol “CI”. The last reported sale price of our common stock on the NYSE on August 29, 2025 was $300.87 per share.

We or any selling security holders may offer and sell these securities to or through one or more underwriters, dealers or agents, or directly to purchasers, on a continuous or delayed basis. If underwriters, dealers or agents are used to sell the securities, we will name them and describe their compensation in a prospectus supplement or free writing prospectus.

Investing in these securities involves certain risks. You should carefully consider the risk factors included in our periodic reports filed with the Securities and Exchange Commission under the Securities Exchange Act of 1934, as amended, and incorporated by reference herein before you invest in any of our securities. We may also include specific risk factors in an applicable prospectus supplement under the heading “Risk Factors.”

Neither the Securities and Exchange Commission nor any state securities regulator has approved or disapproved of these securities, or determined if this prospectus is truthful or complete. Any representation to the contrary is a criminal offense.

This prospectus is part of an automatic “shelf” registration statement on Form S-3 that we filed with the Securities and Exchange Commission, which we refer to as the “SEC,” as a “well-known seasoned issuer” as defined in Rule 405 under the Securities Act of 1933, as amended (the “Securities Act”). This prospectus provides you with a general description of the securities we may offer. Each time we use this prospectus to offer securities, we will provide a prospectus supplement and, if applicable, a pricing supplement. The prospectus supplement and any applicable pricing supplement will describe the specific amounts, prices and other material terms of the securities being offered at that time. The prospectus supplement and any applicable pricing supplement may also add, update or change the information in this prospectus. You should read this prospectus, the applicable prospectus supplement and any applicable pricing supplement, together with the information contained in the documents referred to under the heading “Where You Can Find More Information.” If there is any inconsistency between information in this prospectus and any prospectus supplement or free writing prospectus, you should rely on the information in the prospectus supplement or free writing prospectus.

We have not authorized anyone to provide any information other than that contained or incorporated by reference in this prospectus, any prospectus supplement or in any free writing prospectus prepared by or on behalf of us or to which we have referred you. We take no responsibility for, and can provide no assurance as to the reliability of, any other information that others may give you. We are not making an offer of these securities or a solicitation of your offer to buy these securities in any state where the offer or solicitation is not permitted or legal. You should not assume that the information contained in or incorporated by reference in this prospectus is accurate or complete as of any date other than the date on the front of this prospectus.

Unless otherwise mentioned or unless the context requires otherwise, when used in this prospectus, the terms “we,” “our” and “us” refer to The Cigna Group and its consolidated subsidiaries, and the term the “Company” refers to The Cigna Group, not including its consolidated subsidiaries. Unless the context otherwise requires, “including” means including without limitation.

This prospectus and the documents incorporated by reference herein contain forward-looking statements within the meaning of the Private Securities Litigation Reform Act of 1995. Forward-looking statements are based on The Cigna Group’s current expectations and projections about future trends, events and uncertainties. These statements are not historical facts. Forward-looking statements may include, among others, statements concerning future financial or operating performance, including our ability to improve the health and vitality of those we serve; future growth, business strategy, and strategic or operational initiatives; economic, regulatory or competitive environments, particularly with respect to the pace and extent of change in these areas and the impact of developing inflationary and interest rate pressures; financing or capital deployment plans and amounts available for future deployment; our prospects for growth in the coming years; strategic transactions and their expected benefits; and other statements regarding The Cigna Group’s future beliefs, expectations, plans, intentions, liquidity, cash flows, financial condition or performance. You may identify forward-looking statements by the use of words such as “believe,” “expect,” “project,” “plan,” “intend,” “anticipate,” “estimate,” “predict,” “potential,” “may,” “should,” “will” or other words or expressions of similar meaning, although not all forward-looking statements contain such terms.

Forward-looking statements are subject to risks and uncertainties, both known and unknown, that could cause actual results to differ materially from those expressed or implied in forward-looking statements. Such risks and uncertainties include, but are not limited to: our ability to achieve our strategic and operational initiatives; our ability to adapt to changes in an evolving and rapidly changing industry; our ability to compete effectively, differentiate our products and services from those of our competitors and maintain or increase market share; price competition, inflation and other pressures that could compress our margins or result in premiums that are insufficient to cover the cost of services delivered to our customers; the potential for actual claims to exceed our estimates related to expected medical claims; our ability to develop and maintain satisfactory relationships with health care payors, physicians, hospitals, other health service providers and with producers and consultants; our ability to maintain relationships with one or more key pharmaceutical manufacturers or if payments made or discounts provided decline; changes in the pharmacy provider marketplace or pharmacy networks; changes in drug pricing or industry pricing benchmarks; our ability to invest in and properly maintain our information technology and other business systems; our ability to prevent or contain effects of a potential cyberattack or other privacy or data security incident; risks related to our use of artificial intelligence and machine learning; political, legal, operational, regulatory, economic and other risks that could affect our multinational operations, including currency exchange rates; risks related to strategic transactions and realization of the expected benefits of such transactions as well as integration or separation difficulties or underperformance relative to expectations, which could lead to an impairment charge; dependence on success of relationships with third parties; risk of significant disruption within our operations or among key suppliers or third parties; potential liability in connection with managing medical practices and operating pharmacies, onsite clinics and other types of medical facilities; the substantial level of government regulation over our business and the potential effects of new laws or regulations or changes in existing laws or regulations; uncertainties surrounding participation in government-sponsored programs and providing services to payors who participate in government-sponsored programs; the outcome of litigation, regulatory audits and investigations; compliance with applicable privacy, security and data laws, regulations and standards; potential failure of our prevention, detection and control systems; unfavorable economic and market conditions, the risk of a recession or other economic downturn and resulting impact on employment metrics, stock market or changes in interest rates; risks related to a downgrade in financial strength ratings of our insurance subsidiaries; the impact of our significant indebtedness and the potential for further indebtedness in the future; and credit risk related to our reinsurers.

This list of important factors is not intended to be exhaustive. The discussions in our Annual Report on Form 10-K for the year ended December 31, 2024, including the “Risk Factors” and “Management’s Discussion and Analysis of Financial Condition and Results of Operations” sections therein, as such discussions may be updated from time to time in our periodic filings with the SEC incorporated by reference herein, include both expanded discussion of these factors and additional risk factors and uncertainties that could affect the matters discussed in the forward-looking statements. The Cigna Group does not assume any obligation to update any forward-looking statements, whether as a result of new information, future events or otherwise, except as required by law.

You should not place undue reliance on forward-looking statements, which speak only as of the date they are made, are not guarantees of future performance or results and are subject to risks, uncertainties and assumptions that are difficult to predict or quantify. The Cigna Group undertakes no obligation to update or revise any forward-looking statement, whether as a result of new information, future events or otherwise, except as may be required by law.

We file annual, quarterly and current reports, proxy statements and other information with the SEC under the Securities Exchange Act of 1934, as amended (the “Exchange Act”). The SEC maintains a website that contains reports, proxy statements and other information, including those filed by The Cigna Group, at www.sec.gov. You may also access the SEC filings and obtain other information about The Cigna Group through the website www.thecignagroup.com. Information on, or accessible through, our website is expressly not incorporated by reference into, and does not constitute a part of, this prospectus or any accompanying prospectus supplement, except for the SEC filings posted thereon that are referenced below.

This prospectus is part of the registration statement and does not contain all of the information included in the registration statement.

Whenever a reference is made in this 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, 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 is an important part of this prospectus, and information that we will file later with the SEC (including any prospectus supplement) will automatically update and supersede this information.

This prospectus 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. 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 or any accompanying prospectus supplement or in any documents previously incorporated by reference have been modified or superseded.

We also incorporate by reference into this prospectus all documents filed by us under Section 13(a), 13(c), 14 or 15(d) of the Exchange Act on or after the date of this prospectus until the offering of the particular securities covered by a prospectus supplement has been terminated or completed, other than any portion of the respective filings that are furnished, rather than filed, under the applicable SEC rules. This additional information is a part of this prospectus from the date of filing of those documents.

Unless we inform you otherwise in a prospectus supplement or free writing prospectus, the net proceeds from the sale of the securities will be added to The Cigna Group’s general funds and used for general corporate purposes, including the repayment of indebtedness.

We will not receive any proceeds from sales of securities offered by any selling security holders under this prospectus and the applicable prospectus supplement.

This prospectus describes certain general terms and provisions of the debt securities. The debt securities will be our direct, unsecured obligations. When we offer to sell a particular series of debt securities, we will describe the specific terms of the debt securities in a supplement to this prospectus. The prospectus supplement will also indicate whether the general terms and provisions described in this prospectus apply to a particular series of debt securities. The debt securities will be issued under one or more base indentures, together with related supplemental indentures or officers’ certificates, between us and U.S. Bank Trust Company, National Association, as successor to U.S. Bank National Association, as trustee, or another trustee named in the prospectus supplement (the “Trustee”), including under the indenture dated as of September 17, 2018, between The Cigna Group and U.S. Bank National Association, as Trustee (together with any related supplemental indentures or officers’ certificates, the “existing indenture”). We refer herein to each of the existing indenture and any other indenture under which debt securities will be issued pursuant to this prospectus as the “indenture.” The terms of the indenture and any debt securities issued thereunder will be set forth in the prospectus supplement relating to such debt securities.

We have summarized some terms of the existing indenture below. We expect that the terms of the indenture, if other than the existing indenture, will be substantially similar to the existing indenture; however, we will describe the specific terms of the debt securities to be issued under the indenture in a supplement to this prospectus. The below summary of the existing indenture is not complete. The existing indenture is incorporated by reference as an exhibit to the registration statement of which this prospectus is a part. You should read the existing indenture for a complete statement of the provisions summarized in this prospectus and for provisions that may be important to you. We sometimes refer below to specific sections of the existing indenture. When we do so, we indicate where you can find the relevant section in the existing indenture by noting the section number in parentheses. When we do refer to specific sections contained in the existing indenture or terms defined in the existing indenture, including important terms, which we capitalize here, we use them in this prospectus in the same way we use them in the existing indenture, and you should refer to the existing indenture itself for detailed, specific, legal descriptions. In this section, “Description of Debt Securities,” when we refer to “we,” “our” or “us,” we refer to The Cigna Group, not including its consolidated subsidiaries. The existing indenture is subject to and governed by the Trust Indenture Act of 1939, as amended.

The debt securities will be our unsecured and unsubordinated obligations and will rank equally with all of our existing and future senior unsecured and unsubordinated indebtedness, and senior in right of payment to all of our future indebtedness that is subordinated in right of payment to the debt securities. The debt securities will effectively rank junior to any of our existing and future secured obligations to the extent of the value of the collateral securing such obligations.

Because a significant part of our operations are conducted through subsidiaries, a significant portion of our cash flow, and consequently, our ability to service debt, including the debt securities, is dependent upon the earnings of our subsidiaries and the transfer of funds by those subsidiaries to us in the form of dividends or other transfers.

In addition, because the debt securities will not be guaranteed by any of our subsidiaries, claims in respect of the debt securities will be structurally subordinated to claims of creditors against our subsidiaries, including policy holders, trade creditors, debtholders, secured creditors, taxing authorities, guarantee holders and any preferred shareholders, except to the extent that we are recognized as a creditor of our subsidiary. Any claims of The Cigna Group as the creditor of its subsidiary would be subordinate to any security interest in the assets of such subsidiary and any indebtedness of such subsidiary senior to that held by us.

In addition to general state law restrictions on payments of dividends and other distributions to shareholders applicable to all corporations, health maintenance organizations and insurance companies, including some of The Cigna Group’s direct and indirect subsidiaries, are subject to further state insurance regulations that, among other things, may require those companies to maintain certain levels of equity and restrict the amount of dividends and other distributions that may be paid to The Cigna Group.

The existing indenture does not limit the amount of debt securities that we may issue under them. We may issue debt securities under the existing indenture up to an aggregate principal amount as we may authorize from time to time.

The prospectus supplement will describe the terms of any debt securities being offered, including:

We may from time to time, without notice to or the consent of the holders of any series of debt securities, create and issue further debt securities of any such series ranking equally with, and having the same terms and conditions as, the debt securities of such series in all respects (or in all respects other than the payment of interest accruing prior to the issue date of such further debt securities); provided that if such additional debt securities are not fungible with the initial debt securities of such series for U.S. federal income tax purposes, such additional debt securities will have a separate CUSIP number.

Unless we tell you otherwise in a prospectus supplement, when we use the term “Event of Default” with respect to debt securities of any series we mean:

An Event of Default with respect to debt securities of a particular series may not constitute an Event of Default with respect to debt securities of any other series of debt securities.

If an Event of Default under the existing indenture occurs with respect to the debt securities of any series and is continuing, then the Trustee or the holders of at least 25% in principal amount of the outstanding debt securities of that series may require us to repay immediately the entire principal amount (or, if the debt securities of that series are Original Issue Discount Securities (as defined in the existing indenture), such portion of the principal amount as may be specified in the terms of that series) of all outstanding debt securities of that series; provided, however, that under certain circumstances the holders of a majority in aggregate principal amount of outstanding debt securities of that series may rescind or annul such acceleration and its consequences. (Section 5.02)

The existing indenture contains a provision entitling the Trustee, subject to the duty of the Trustee during a default to act with the required standard of care (Section 6.01), to be indemnified by the holders of debt securities before proceeding to exercise any right or power under that existing indenture at the request of such holders. (Section 6.03) Subject to these provisions in the existing indenture for the indemnification of the Trustee and certain other limitations, the holders of a majority in aggregate principal amount of the debt securities of each affected series then Outstanding (as defined in the existing indenture) may direct the time, method and place of conducting any proceeding for any remedy available to the Trustee or exercising any trust or power conferred on the Trustee. (Sections 5.12 and 5.13)

The existing indenture provides that the Trustee may withhold notice to the holders of the debt securities of any default (except in payment of principal (or premium, if any) or interest, if any) if the Trustee determines in good faith that it is in the interest of the holders of the debt securities to do so. (Section 6.02)

The existing indenture provides that holders of the outstanding debt securities of any series may seek to institute a proceeding with respect to the existing indenture or for any remedy thereunder only after:

These limitations do not apply, however, to a suit instituted by a holder of a debt security for enforcement of payment of the principal of (or premium, if any) or interest, if any, on or after the respective due dates expressed in such debt security. (Section 5.08)

The existing indenture contains a covenant under which we are required to furnish to the Trustee an officers’ certificate, within 120 days after the end of each fiscal year, as to the compliance with all terms, provisions and conditions of the existing indenture, or if we are in default, specifying all such defaults and the nature and status thereof of which we may have knowledge. (Section 10.07)

The existing indenture (Section 9.01) provides that we, together with the Trustee, may enter into supplemental indentures without the consent of the holders of debt securities to:

Other amendments and modifications of the existing indenture may be made with the consent of the holders of not less than a majority of the aggregate principal amount of each series of the outstanding debt securities affected by the amendment or modification; provided, however, no modification or amendment may, without the consent of the holder of each outstanding debt security affected:

The holders of at least a majority of the aggregate principal amount of the outstanding debt securities of any series may, on behalf of all holders of that series, waive our required compliance with certain restrictive provisions of the existing indenture and may waive any past default under the existing indenture, except a default in the payment of principal, premium or interest or in the performance of certain covenants. (Section 5.13)

The existing indenture provides that so long as any of the debt securities issued under the existing indenture remains outstanding, we will not, and we will not permit any of our subsidiaries to, directly or indirectly, create, issue, assume, incur or guarantee any indebtedness for borrowed money secured by a mortgage, pledge, lien, security interest or other encumbrance of any nature on any of the common stock of a Designated Subsidiary, which common stock is directly or indirectly owned by us, unless our obligations under the debt securities and, if we so elect, any other of our indebtedness ranking on a parity with, or prior to, the debt securities, shall be secured equally and ratably with, or prior to, such secured indebtedness for borrowed money so long as it is outstanding and is so secured. (Section 10.05)

“Designated Subsidiary” means each of Cigna Holding Company, Connecticut General Life Insurance Company, Evernorth Health, Inc., f/k/a Express Scripts Holding Company, Express Scripts, Inc. and Medco Health Solutions, Inc., so long as it remains a subsidiary, or any subsidiary which is a successor of such Designated Subsidiary. (Section 1.01)

The existing indenture provides that we may not consolidate with or merge with or into any other person (other than in a merger or consolidation in which we are the surviving person) or sell our properties and assets as, or substantially as, an entirety to any person unless:

Upon compliance with the foregoing provisions, the successor or purchaser will succeed to, and be substituted for, The Cigna Group under the existing indenture with the same effect as if such successor or purchaser had been the original obligor under the debt securities, and thereafter The Cigna Group will be relieved of all obligations and covenants under the existing indenture and the debt securities. (Section 8.02)

Unless otherwise indicated in a prospectus supplement with respect to a particular series of debt securities, the debt securities will not contain an option for the holders of such debt to require us to purchase all or a portion of such debt securities or any other protection in the event we have a change in control or in the event of a highly leveraged transaction (whether or not such transaction results in a change in control).

If we irrevocably deposit, in trust, with the Trustee (or other qualifying trustee), sufficient cash and/or specified government obligations (in the opinion of a nationally recognized firm of independent public accountants) to pay the principal of (and premium, if any) and interest and any other sums due on the scheduled due date for the debt securities of a particular series, then at our option and subject to certain conditions (including the absence of an Event of Default):

If we exercise our legal defeasance option, payment of such debt securities may not be accelerated because of an Event of Default. If we exercise our covenant defeasance option, payment of such debt securities may not be accelerated by reference to the covenants from which we have been released or pursuant to Events of Default referred to above which are no longer applicable. If we fail to comply with our remaining obligations with respect to such debt securities under the existing indenture after we exercise the covenant defeasance option and such debt securities are declared due and payable because of the occurrence of any Event of Default, the amount of money and government obligations on deposit with the Trustee may be insufficient to pay amounts due on the debt securities of such series at the time of the acceleration resulting from such Event of Default. However, we will remain liable for such payments. (Section 10.06)

Under current United States federal income tax laws, a legal defeasance would be treated as an exchange of the relevant debt securities in which holders of those debt securities might recognize gain or loss. Unless accompanied by other changes in the terms of the debt securities, a covenant defeasance generally should not be treated as a taxable exchange. In order to exercise our defeasance options, we must deliver to the Trustee an opinion of counsel to the effect that the deposit and related defeasance would not cause the holders of the debt securities to recognize income, gain or loss for Federal income tax purposes. In the case of legal defeasance, such opinion of counsel must be based on (i) an Internal Revenue Service ruling or (ii) a change in the applicable United States federal income tax law occurring since the date of the existing indenture.

The existing indenture provides that upon our request, the existing indenture will cease to be of further effect (except as to any surviving rights of registration of transfer or exchange of debt securities expressly provided for therein) as to all outstanding debt securities of any series, and the Trustee, at the expense of us, will execute proper instruments acknowledging such satisfaction and discharge of the existing indenture with respect to such debt securities, when:

The existing indenture provides that no recourse shall be had for the payment of principal, premium, if any, or interest, if any, or any debt security, or for any claim based on or in respect of any debt security or the existing indenture or any supplemental indenture, against any incorporator, or against any past, present or future stockholder, officer, director, employee or agent of ours or of any successor person thereof under any law, statute or constitutional provision or by the enforcement of any assessment or by any legal or equitable proceeding or otherwise. Each holder, by accepting the debt securities, waives and releases all such liability.

U.S. Bank Trust Company, National Association, as successor to U.S. Bank National Association, is the Trustee under our existing indenture. We maintain customary banking relationships in the ordinary course of business with the Trustee and its affiliates.

The existing indenture is governed by and shall be construed in accordance with the internal laws of the State of New York, without regard to conflicts of laws principles thereof.

Each debt security will be represented either by a certificate issued in definitive form to a particular investor or by one or more global securities representing the entire issuance of securities. Certificated securities in definitive form and global securities will be issued in registered form.

Definitive securities name you or your nominee as the owner of the security, and in order to transfer or exchange these securities or to receive payments other than interest or other interim payments, you or your nominee must physically deliver the securities to the Trustee. Global securities name a depositary or its nominee as the owner of the debt securities represented by the global securities.

We may issue the debt securities in the form of one or more fully registered global securities that will be deposited with a depositary or its nominee identified in the applicable prospectus supplement and registered in the name of that depositary or nominee. In those cases, one or more global securities will be issued in a denomination or aggregate denominations equal to the portion of the aggregate principal or face amount of the securities to be represented by global securities. Unless and until it is exchanged in whole for securities in definitive registered form, a global security may not be transferred except as a whole by and among the depositary for the global security, the nominees of the depositary or any successors of the depositary or those nominees.

If not described below, any specific terms of the depositary arrangement with respect to any securities to be represented by a global security will be described in the prospectus supplement relating to those securities. (Sections 2.04 and 3.05) We anticipate that the following provisions will apply to all depositary arrangements.

Ownership of beneficial interests in a global security will be limited to persons, called participants, that have accounts with the depositary.

Upon the issuance of a global security, the depositary will credit, on its book-entry registration and transfer system, the participants’ accounts with the respective principal or face amounts of the securities beneficially owned by the participants. Any dealers, underwriters or agents participating in the distribution of the securities will designate the accounts to be credited. Ownership of beneficial interests in a global security will be shown on, and the transfer of ownership interests will be effected only through, records maintained by the depositary, with respect to interests of participants, and on the records of participants, with respect to interests of persons holding through participants. The laws of some states may require that some purchasers of securities take physical delivery of these securities in definitive form. These laws may impair your ability to own, transfer or pledge beneficial interests in global securities.

So long as the depositary, or its nominee, is the registered owner of a global security, that depositary or its nominee, as the case may be, will be considered the sole owner or holder of the securities represented by the global security for all purposes under the existing indenture. Except as described below, owners of beneficial interests in a global security will not be entitled to have the securities represented by the global security registered in their names, will not receive or be entitled to receive physical delivery of the securities in definitive form and will not be considered the owners or holders of the securities under the existing indenture. Accordingly, each person owning a beneficial interest in a global security must rely on the procedures of the depositary for that global security and, if that person is not a participant, on the procedures of the participant through which the person owns its interest, to exercise any rights of a holder under the existing indenture. We understand that under existing industry practices, if we request any action of holders or if an owner of a beneficial interest in a global security desires to give or take any action that a holder is entitled to give or take under the existing indenture, the depositary for the global security would authorize the participants holding the relevant beneficial interests to give or take that action, and the participants would authorize beneficial owners owning through them to give or take that action or would otherwise act upon the instructions of beneficial owners holding through them.

Principal (or premium, if any) and interest payments on debt securities represented by a global security registered in the name of a depositary or its nominee will be made to the depositary or its nominee, as the case may be, as the registered owner of the global security. Neither The Cigna Group nor the Trustee nor any agent of The Cigna Group or the Trustee will have any responsibility or liability for any aspect of the records relating to payments made on account of beneficial ownership interests in the global security or for maintaining, supervising or reviewing any records relating to those beneficial ownership interests.

We expect that the depositary for any of the securities represented by a global security, upon receipt of any payment of principal, premium, interest or other distribution of underlying securities or other property to holders of that global security, will immediately credit participants’ accounts in amounts proportionate to their respective beneficial interests in that global security as shown on the records of the depositary. We also expect that payments by participants to owners of beneficial interests in a global security held through participants will be governed by standing customer instructions and customary practices, and will be the responsibility of those participants.

If the depositary for any of these securities represented by a global security is at any time unwilling or unable to continue as depositary or ceases to be a clearing agency registered under the Exchange Act, and a successor depositary registered as a clearing agency under the Exchange Act is not appointed by us within 90 days, we will issue securities in definitive form in exchange for the global security that had been held by the depositary. In addition, we may at any time and in our sole discretion decide not to have any of the securities represented by one or more global securities. If we make that decision, we will issue securities in definitive form in exchange for the global security or securities representing those securities. Any securities issued in definitive form in exchange for a global security will be registered in the name or names that the depositary gives to the Trustee or relevant agent of ours or theirs. It is expected that the depositary’s instructions will be based upon directions received by the depositary from participants with respect to ownership of beneficial interests in the global security that had been held by the depositary.

The following description of our common stock is based upon our Restated Certificate of Incorporation (“Certificate of Incorporation”), our Amended and Restated By-Laws (“By-Laws”) and applicable provisions of law as currently in effect. We have summarized certain portions of the Certificate of Incorporation and By-Laws below. This summary is not complete and is qualified by the Certificate of Incorporation and the By-Laws, which are incorporated by reference in the registration statement of which this prospectus forms a part.

Certain provisions of the Delaware General Corporation Law, the Certificate of Incorporation and the By-Laws summarized in the following paragraphs may have an anti-takeover effect. This may delay, defer or prevent a tender offer or takeover attempt that a stockholder might consider in its best interests, including those attempts that might result in a premium over the market price for its shares.

The Company is authorized to issue 600,000,000 shares of common stock, par value $0.01 per share, of which 266,928,075 shares were outstanding at July 25, 2025.

Holders of common stock are entitled to receive such dividends as the board of directors of the Company may from time to time declare. Payment of dividends on the common stock will at all times be subject to, among other things, prior satisfaction of dividend and sinking fund requirements, if any, of any series of preferred stock that may then be outstanding, and the availability of funds to the Company, which in turn may be subject to fixed payment obligations which the Company may incur in the future, and the ability of the Company’s insurance subsidiaries to declare and pay dividends under applicable insurance regulatory requirements. No shares of preferred stock are outstanding as of the date of this prospectus.

All directors of the Company currently hold one-year terms. Any director may be removed, with or without cause, at any time, by a majority of the voting power of the issued and outstanding capital stock of the Company entitled to vote at an election for directors. Holders of common stock have one vote per share and have no cumulative voting rights, which means that the holders of more than 50% of the shares voting for the election of directors can elect 100% of the directors and the holders of the remaining shares are not able to elect any directors. The Company has adopted a majority voting standard for the election of directors in uncontested elections. Under this standard, each director must receive a majority of the votes cast with respect to that director. This means that the number of votes cast “for” a director nominee must exceed the number of votes cast “against” that nominee for the director to be elected. In general, each director agrees to tender, and not withdraw, his or her resignation if he or she does not receive a majority of the votes cast at an annual meeting of shareholders at which such director is a nominee for election. The Company’s Corporate Governance Committee will make a recommendation to the Company’s board of directors on whether to accept the resignation. The Company’s board of directors has discretion to accept or reject the resignation. In contested elections, the voting standard is a plurality of votes cast.

Subject to the rights of creditors and the liquidation preferences of holders of preferred stock, the holders of common stock are entitled to share ratably in the remaining assets of the Company in the event of its voluntary or involuntary liquidation or dissolution. Holders of common stock have no preemptive rights. All shares of common stock presently outstanding are, and all such shares to be issued pursuant to this prospectus will be, fully paid and nonassessable. Shares of the Company’s common stock are not convertible into shares of any other class of capital stock.

The Certificate of Incorporation grants the Company the right to amend, alter, change or repeal any provision in the Certificate of Incorporation in the manner prescribed by statute. Under Section 242 of the Delaware General Corporation Law, unless the Certificate of Incorporation requires a greater vote, a proposed amendment to the Certificate of Incorporation must be approved by the affirmative vote of a majority of the voting power of the outstanding stock entitled to vote thereon and a majority of the outstanding stock of each class entitled to vote as a class. The Company’s By-Laws may be adopted, amended or repealed by majority vote of the capital stock of the Company outstanding and entitled to vote thereon, or by the Company’s board of directors without any vote of the stockholders. Such provisions could inhibit a change in control in situations that the board of directors determines are not adequate or in the best interests of shareholders, or that do not meet specified fair price criteria and procedural conditions. In some circumstances, some or all shareholders could be denied the opportunity to realize a premium over the then-prevailing market price for the shares.

The Company’s Certificate of Incorporation authorizes the issuance of 25,000,000 shares of preferred stock, par value $1.00 per share. No shares of preferred stock are outstanding as of the date of this prospectus. The Company’s preferred stock may be issued from time to time in one or more series, without shareholder approval, when authorized by the board of directors. Subject to limitations prescribed by law, the board of directors is authorized to determine the voting powers (if any), designations, preferences and relative, participating, optional or other special rights, and qualifications, limitations or restrictions thereof, for each series of preferred stock that may be issued, and to fix the number of shares of each such series.

We will include the specific terms of each series of the preferred stock being offered in a supplement to this prospectus.

Section 203 of the Delaware General Corporation Law prohibits a defined set of transactions between a Delaware corporation, such as us, and an interested stockholder. An interested stockholder is defined as a person who, together with any affiliates or associates of such person, beneficially owns, directly or indirectly, 15% or more of the outstanding voting shares of a Delaware corporation. This provision may prohibit business combinations between an interested stockholder and a corporation for a period of three years after the date the interested stockholder becomes an interested stockholder. The term business combination is broadly defined to include mergers, consolidations, sales or other dispositions of assets having a total value in excess of 10% of the consolidated assets of the corporation, and some other transactions that would increase the interested stockholder’s proportionate share ownership in the corporation.

This prohibition is effective unless:

In general, the prohibitions do not apply to business combinations with persons who were shareholders before we became subject to Section 203.

In addition, our Certificate of Incorporation provides that, subject to certain limited exceptions, a business combination with or upon a proposal by a related person (as defined therein) requires the affirmative vote of the holders of at least a majority of the voting power of all outstanding shares of our common stock and preferred stock entitled to vote, voting together as a single class. Such affirmative votes shall be required notwithstanding the fact that no vote may be required, or that a lesser percentage may be specified, by law or our board of directors.

Under our By-Laws, vacancies and newly-created directorships resulting from any increase in the size of our board may be filled by our board, even if the directors then on the board do not constitute a quorum or only one director is left in office. These provisions, together with the provisions of Section 203 of the Delaware General Corporation Law, could have the effect of delaying, deferring or preventing a change in control or the removal of existing management, of deterring potential acquirors from making an offer to our shareholders and of limiting any opportunity to realize premiums over the then-prevailing market prices for our common stock in connection therewith. This could be the case notwithstanding that a majority of our shareholders might benefit from such a change in control or offer.

Computershare Inc. serves as the registrar and transfer agent for the common stock.

Our common stock is listed on the New York Stock Exchange under the trading symbol “CI”.

We may issue warrants to purchase our debt or equity securities or securities of third parties or other rights, including rights to receive payment in cash or securities based on the value, rate or price of one or more specified commodities, currencies, securities or indices, or any combination of the foregoing. Warrants may be issued independently or together with any other securities and may be attached to, or separate from, such securities. Each series of warrants will be issued under a separate warrant agreement to be entered into between us and a warrant agent. The terms of any warrants to be issued and a description of the material provisions of the applicable warrant agreement will be set forth in the applicable prospectus supplement.

We may issue purchase contracts for the purchase or sale of:

Each purchase contract will entitle or obligate the holder thereof to purchase or sell, and obligate us to sell or purchase, on specified dates, such securities, currencies or commodities at a specified purchase price, which may be based on a formula, all as set forth in the applicable prospectus supplement. We may, however, satisfy our obligations, if any, with respect to any purchase contract by delivering the cash value of such purchase contract or the cash value of the property otherwise deliverable or, in the case of purchase contracts on underlying currencies, by delivering the underlying currencies, as set forth in the applicable prospectus supplement. The applicable prospectus supplement will also specify the methods by which the holders may purchase or sell such securities, currencies or commodities and any acceleration, cancellation or termination provisions or other provisions relating to the settlement of a purchase contract.

The purchase contracts may require us to make periodic payments to the holders thereof or vice versa, which payments may be deferred to the extent set forth in the applicable prospectus supplement, and those payments may be unsecured or prefunded on some basis. The purchase contracts may require the holders thereof to secure their obligations in a specified manner to be described in the applicable prospectus supplement. The purchase contracts may require holders to satisfy their obligations thereunder when the purchase contracts are issued or at settlement. Our obligation to settle any pre-paid purchase contracts on the relevant settlement date may constitute indebtedness.

We may issue units consisting of one or more purchase contracts, warrants, debt securities, shares of preferred stock, shares of common stock or any combination of such securities. The terms of any units to be issued and a description of the material provisions of the applicable unit agreement will be set forth in the applicable prospectus supplement.

Selling security holders to be named in a prospectus supplement may, from time to time, offer and sell some or all of our securities held by them pursuant to this prospectus and the applicable prospectus supplement. Such selling security holders may sell our securities held by them to or through underwriters, dealers or agents or directly to purchasers or as otherwise set forth in the applicable prospectus supplement. See “Plan of Distribution.” Such selling security holders may also sell, transfer or otherwise dispose of some or all of our securities held by them in transactions exempt from the registration requirements of the Securities Act.

We will provide you with a prospectus supplement, which will, among other things, set forth the name of each selling security holder and the number of our securities beneficially owned by such selling security holders that are covered by such prospectus supplement.

Any of the securities being offered pursuant to this prospectus and any accompanying prospectus supplement may be sold in any one or more of the following ways from time to time:

We may also issue any of the securities as a dividend or distribution to our shareholders.

In addition, we may enter into derivative transactions with third parties, or sell securities not covered by this prospectus to third parties in privately negotiated transactions. If the applicable prospectus supplement indicates, in connection with such a transaction the third parties may, pursuant to this prospectus and the applicable prospectus supplement, sell securities covered by this prospectus and the applicable prospectus supplement. If so, the third parties may use securities borrowed from us or others to settle such sales and may use securities received from us to close out any related short positions. We may also loan or pledge securities covered by this prospectus and the applicable prospectus supplement to third parties, who may sell the loaned securities or, in an event of default in the case of a pledge, sell the pledged securities pursuant to this prospectus and the applicable prospectus supplement.

The distribution of the securities may be effected from time to time in one or more transactions at a fixed price or prices, which may be changed, at market prices prevailing at the time of sale, at prices related to such prevailing market prices or at negotiated prices.

We may solicit offers to purchase directly. Offers to purchase securities also may be solicited by agents designated by us from time to time. Any such agent involved in the offer or sale of the securities in respect of which this prospectus is delivered will be named, and any commissions payable by us to such agent will be set forth, in the applicable prospectus supplement. Unless otherwise indicated in such prospectus supplement, any such agent will be acting on a reasonable best efforts basis for the period of its appointment. Any such agent may be deemed to be an underwriter, as that term is defined in the Securities Act, of the securities so offered and sold.

If securities are sold by means of an underwritten offering, we will execute an underwriting agreement with an underwriter or underwriters at the time an agreement for such sale is reached, and the names of the specific managing underwriter or underwriters, as well as any other underwriters, the respective amounts underwritten and the terms of the transaction, including commissions, discounts and any other compensation of the underwriters and dealers, if any, will be set forth in the applicable prospectus supplement which will be used by the underwriters to make resales of the securities in respect of which this prospectus is being delivered to the public. If underwriters are utilized in the sale of any securities in respect of which this prospectus is being delivered, such securities will be acquired by the underwriters for their own account and may be resold from time to time in one or more transactions, including negotiated transactions, at fixed public offering prices or at varying prices determined by the underwriters at the time of sale. Securities may be offered to the public either through underwriting syndicates represented by managing underwriters or directly by one or more underwriters. If any underwriter or underwriters are utilized in the sale of securities, unless otherwise indicated in the applicable prospectus supplement, the underwriting agreement will provide that the obligations of the underwriters are subject to certain conditions precedent and that the underwriters with respect to a sale of such securities will be obligated to purchase all such securities if any are purchased.

We may grant to the underwriters options to purchase additional securities, to cover over-allotments, if any, at the initial public offering price (with additional underwriting commissions or discounts), as may be set forth in the prospectus supplement relating thereto. If we grant any over- allotment option, the terms of such over-allotment option will be set forth in the prospectus supplement for such securities.

If a dealer is used in the sale of the securities in respect of which this prospectus is delivered, we will sell such securities to the dealer, as principal. The dealer may then resell such securities to the public at varying prices to be determined by such dealer at the time of resale. Any such dealer may be deemed to be an underwriter, as such term is defined in the Securities Act, of the securities so offered and sold. The name of the dealer and their terms of the transaction will be set forth in the prospectus supplement relating thereto.

Offers to purchase securities may be solicited directly by us and the sale thereof may be made by us directly to institutional investors or others, who may be deemed to be underwriters within the meaning of the Securities Act with respect to any resale thereof. We may also offer securities through agents in connection with a distribution to our shareholders of rights to purchase such securities. The terms of any such sales will be described in the prospectus supplement relating thereto.

We may offer our equity securities into an existing trading market on the terms described in the applicable prospectus supplement.

Underwriters and dealers who may participate in any at-the-market offerings will be described in the prospectus supplement relating thereto.

Pursuant to any standby underwriting agreement entered into in connection with a subscription rights offering to our shareholders, persons acting as standby underwriters may receive a commitment fee for all securities underlying the subscription rights that the underwriter commits to purchase on a standby basis. Additionally, prior to the expiration date with respect to any subscription rights, any standby underwriters in a subscription rights offering to our shareholders may offer such securities on a when-issued basis, including securities to be acquired through the purchase and exercise of subscription rights, at prices set from time to time by the standby underwriters. After the expiration date with respect to such subscription rights, the underwriters may offer securities of the type underlying the subscription rights, whether acquired pursuant to a standby underwriting agreement, the exercise of the subscription rights or the purchase of such securities in the market, to the public at a price or prices to be determined by the underwriters. The standby underwriters may thus realize profits or losses independent of the underwriting discounts or commissions paid by us. If we do not enter into a standby underwriting arrangement in connection with a subscription rights offering to our shareholders, we may elect to retain a dealer-manager to manage such a subscription rights offering for us. Any such dealer-manager may offer securities of the type underlying the subscription rights acquired or to be acquired pursuant to the purchase and exercise of subscription rights and may thus realize profits or losses independent of any dealer-manager fee paid by us.

Securities may also be offered and sold, if so indicated in the applicable prospectus supplement, in connection with a remarketing upon their purchase, in accordance with a redemption or repayment pursuant to their terms, or otherwise, by one or more firms (“remarketing firms”) acting as principals for their own accounts or as agents for us. Any remarketing firm will be identified and the terms of its agreement, if any, with us and its compensation will be described in the applicable prospectus supplement. Remarketing firms may be deemed to be underwriters, as that term is defined in the Securities Act, in connection with the securities remarketed thereby.

If so indicated in the applicable prospectus supplement, we may authorize agents, dealers or underwriters to solicit offers by certain institutions to purchase securities from us at the public offering price set forth in the applicable prospectus supplement pursuant to delayed delivery contracts providing for payment and delivery on the date or dates stated in the applicable prospectus supplement. Such delayed delivery contracts will be subject to only those conditions set forth in the applicable prospectus supplement. A commission indicated in the applicable prospectus supplement will be paid to underwriters and agents soliciting purchases of securities pursuant to delayed delivery contracts accepted by us.

Agents, underwriters, dealers and remarketing firms may be entitled under relevant agreements with us to indemnification by us against certain liabilities, including liabilities under the Securities Act, or to contribution with respect to payments which such agents, underwriters, dealers and remarketing firms may be required to make in respect thereof.

Any underwriter may engage in stabilizing and syndicate covering transactions in accordance with Rule 104 under Regulation M. Rule 104 permits stabilizing bids to purchase the underlying security so long as the stabilizing bids do not exceed a specified maximum. The underwriters may over-allot shares of the securities in

connection with an offering of securities, thereby creating a short position in the underwriters’ account. Syndicate covering transactions involve purchases of the securities in the open market after the distribution has been completed in order to cover syndicate short positions. Stabilizing and syndicate covering transactions may cause the price of the securities to be higher than it would otherwise be in the absence of such transactions. These transactions, if commenced, may be discontinued at any time.

Unless otherwise specified in the applicable prospectus supplement, each series of securities, other than our common stock that is listed on the New York Stock Exchange, will be a new issue and will have no established trading market. We may elect to list any series of securities on an exchange but, unless otherwise specified in the applicable prospectus supplement, we shall not be obligated to do so. In addition, underwriters will not be obligated to make a market in any securities. No assurance can be given as to the liquidity of, or activity in, the trading market for any of the securities.

Agents, underwriters, dealers and remarketing firms may be customers of, engage in transactions with, or perform services for, us and our subsidiaries in the ordinary course of business.

The anticipated date of delivery of securities will be set forth in the applicable prospectus supplement relating to each offer.

Unless otherwise indicated in the applicable prospectus supplement, the validity of our debt securities, common stock, preferred stock, warrants, purchase contracts and units will be passed upon for us by Davis Polk & Wardwell LLP, New York, New York.

The financial statements and management’s assessment of the effectiveness of internal control over financial reporting (which is included in Management’s Annual Report on Internal Control over Financial Reporting) incorporated in this prospectus by reference to the Annual Report on Form 10-K for the year ended December 31, 2024 have been so incorporated in reliance on the report of PricewaterhouseCoopers LLP, an independent registered public accounting firm, given on the authority of said firm as experts in auditing and accounting.

The Cigna Group and certain of its affiliates may each be considered a “party in interest” within the meaning of the Employee Retirement Income Security Act of 1974, as amended (“ERISA”), or a “disqualified person” within the meaning of Section 4975 of the Internal Revenue Code of 1986, as amended (the “Code”), with respect to many employee benefit plans subject to Title I of ERISA or plans, accounts or other arrangements subject to Section 4975 of the Code or entities deemed to hold the assets of such employee benefit plans, plans, accounts or arrangements (collectively, “Plans”). Prohibited transactions within the meaning of ERISA or Section 4975 of the Code may arise, for example, if any securities are acquired by a Plan with respect to which The Cigna Group or any of its affiliates is a service provider, unless such securities are acquired pursuant to an exemption for transactions effected on behalf of such Plan by a “qualified professional asset manager” (commonly known as the “QPAM exemption”) or pursuant to any other available statutory or administrative exemption. There can be no assurance that any such exemptions will be available, or that all of the conditions of any such exemptions will be satisfied, with respect to transactions involving the securities. In addition, certain governmental, church and non-U.S. plans are subject to federal, state, local or non-U.S. laws that are similar to Title I of ERISA or Section 4975 of the Code (“Similar Laws”). Therefore, each purchaser or holder of the securities or any interest therein will be deemed to have represented by its purchase or holding thereof that either (i) it is not and is not using the assets of any Plan or any plan subject to Similar Laws or (ii) its purchase, holding and subsequent disposition of the securities or any interest therein will not constitute or result in a non-exempt prohibited transaction under Section 406 of ERISA or Section 4975 of the Code or in a violation of Similar Laws.

Any Plan or plan subject to Similar Laws proposing to invest in the securities should consult with its legal counsel. The sale of the securities offered hereunder to any Plan or plan subject to Similar Laws is in no respect a representation by The Cigna Group or any of its affiliates or representatives that such an investment is appropriate for or meets all relevant legal requirements with respect to investments by any such Plan or plan subject to Similar Laws generally or any particular Plan or plan subject to Similar Laws.

The following table lists the expenses expected to be incurred by The Cigna Group in connection with the issuance and distribution of securities registered under this registration statement.

Under Section 145 of the Delaware General Corporation Law, the Company is empowered to indemnify its directors and officers in the circumstances therein provided.

Under Article VI of its By-Laws, the Company will indemnify any director or officer of the Company, as well as any other person who is or was a director, officer or employee of the Company or any of its subsidiaries who serve as directors or officers of any other entity at the request of the Company, who was or is a party or is threatened to be made a party to any threatened, pending or completed action, suit or proceeding (other than an action by or in the right of the Company), against expenses (including attorneys’ fees, judgments, fines and amounts paid in settlement actually and reasonably incurred by such person).

The Company is insured against liabilities which it may incur by reason of Article VI of its By-Laws. In addition, directors and officers of the Company, as well as any other persons who serve as directors or officers of any other entity at the request of the Company, are insured, at the Company’s expense, against liabilities which might arise against such persons in any such capacity, whether or not the Company would have the power to indemnify such persons against such liability under the provisions of Article VI.

Section 102(b)(7) of the Delaware General Corporation Law permits a corporation to provide in its certificate of incorporation that a director or officer of the corporation shall not be personally liable to the corporation or its stockholders for monetary damages for breach of fiduciary duty as a director or officer, except for liability of (i) a director or officer for any breach of the director’s or officer’s duty of loyalty to the corporation or its stockholders, (ii) a director or officer for acts or omissions not in good faith or which involve intentional misconduct or a knowing violation of law, (iii) a director for unlawful payments of dividends or unlawful stock repurchases, redemptions or other distributions, (iv) a director or officer for any transaction from which the director or officer derived an improper personal benefit or (v) an officer in any action by or in the right of the corporation.

The Company’s Certificate of Incorporation provides that, to the fullest extent permitted by the Delaware General Corporation Law, a director or officer shall not be liable to the registrant or its stockholders for monetary damages for breach of fiduciary duty as a director or officer.

The Exhibit Index appearing before the signature pages below is incorporated herein by reference.

(a) The undersigned registrant hereby undertakes:

(1) To file, during any period in which offers or sales are being made, a post-effective amendment to this registration statement:

(i) To include any prospectus required by Section 10(a)(3) of the Securities Act;

(ii) To reflect in the prospectus any facts or events arising after the effective date of this registration statement (or the most recent post-effective amendment thereof) which, individually or in the aggregate, represent a fundamental change in the information set forth in the registration statement. Notwithstanding the foregoing, any increase or decrease in volume of securities offered (if the total dollar value of securities offered would not exceed that which was registered) and any deviation from the low or high end of the estimated maximum offering range may be reflected in the form of prospectus filed with the SEC pursuant to Rule 424(b) if, in the aggregate, the changes in volume and price represent no more than a 20% change in the maximum aggregate offering price set forth in the “Calculation of Filing Fee Tables” or “Calculation of Registration Fee” table, as applicable, in the effective registration statement; and

(iii) To include any material information with respect to the plan of distribution not previously disclosed in the registration statement or any material change to such information in the registration statement;

(2) That, for the purpose of determining any liability under the Securities Act, each such post-effective amendment shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.

(3) To remove from registration by means of a post-effective amendment any of the securities being registered which remain unsold at the termination of the offering.

(5) That, for the purpose of determining liability under the Securities Act to any purchaser:

(i) Each prospectus filed by the registrant pursuant to Rule 424(b)(3) shall be deemed to be part of the registration statement as of the date the filed prospectus was deemed part of and included in the registration statement; and

(ii) Each prospectus required to be filed pursuant to Rule 424(b)(2), (b)(5) or (b)(7) as part of a registration statement in reliance on Rule 430B relating to an offering made pursuant to Rule 415(a)(1)(i), (vii) or (x) for the purpose of providing the information required by Section 10(a) of the Securities Act shall be deemed to be part of and included in the registration statement as of the earlier of the date such form of prospectus is first used after effectiveness or the date of the first contract of sale of securities in the offering described in the prospectus. As provided in Rule 430B, for liability purposes of the issuer and any person that is at that date an underwriter, such date shall be deemed to be a new effective date of the registration statement relating to the securities in the registration statement to which that prospectus relates, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof. Provided, however, that no statement made in a registration statement or prospectus that is part of the registration statement or made in a document incorporated or deemed incorporated by reference into the registration statement or prospectus that is

part of the registration statement will, as to a purchaser with a time of contract of sale prior to such effective date, supersede or modify any statement that was made in the registration statement or prospectus that was part of the registration statement or made in any such document immediately prior to such effective date.

(6) That, for the purpose of determining liability of the registrant under the Securities Act to any purchaser in the initial distribution of the securities, the undersigned registrant undertakes that in a primary offering of securities of the undersigned registrant pursuant to this registration statement, regardless of the underwriting method used to sell the securities to the purchaser, if the securities are offered or sold to such purchaser by means of any of the following communications, the undersigned registrant will be a seller to the purchaser and will be considered to offer or sell such securities to such purchaser:

(i) Any preliminary prospectus or prospectus of the undersigned registrant relating to the offering required to be filed pursuant to Rule 424;

(ii) Any free writing prospectus relating to the offering prepared by or on behalf of the undersigned registrant or used or referred to by the undersigned registrant;

(iii) The portion of any other free writing prospectus relating to the offering containing material information about the undersigned registrant or its securities provided by or on behalf of the undersigned registrant; and

(iv) Any other communication that is an offer in the offering made by the undersigned registrant to the purchaser.

(b) The undersigned registrant undertakes that, for purposes of determining any liability under the Securities Act, each filing of the registrant’s annual report pursuant to Section 13(a) or Section 15(d) of the Exchange Act (and, where applicable, each filing of an employee benefit plan’s annual report pursuant to Section 15(d) of the Exchange Act) that is incorporated by reference in the registration statement shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.

(h) Insofar as indemnification for liabilities arising under the Securities Act may be permitted to directors, officers and controlling persons of the registrant pursuant to the foregoing provisions, or otherwise, the registrant has been advised that in the opinion of the SEC such indemnification is against public policy as expressed in the Securities Act and is, therefore, unenforceable. In the event that a claim for indemnification against such liabilities (other than the payment by the registrant of expenses incurred or paid by a director, officer or controlling person of the registrant in the successful defense of any action, suit or proceeding) is asserted by such director, officer or controlling person in connection with the securities being registered, the registrant will, unless in the opinion of its counsel the matter has been settled by controlling precedent, submit to a court of appropriate jurisdiction the question whether such indemnification by it is against public policy as expressed in the Securities Act and will be governed by the final adjudication of such issue.

Pursuant to the requirements of the Securities Act of 1933, the registrant certifies that it has reasonable grounds to believe that it meets all of the requirements for filing on Form S-3 and has duly caused this registration statement to be signed on its behalf by the undersigned, thereunto duly authorized, in the City of Bloomfield, State of Connecticut, on September 2, 2025.

KNOW ALL PERSONS BY THESE PRESENTS, that each person whose signature appears below, officers and/or directors of The Cigna Group, a Delaware corporation, hereby makes, designates, constitutes and appoints NICOLE S. JONES and ANDREA NELSON, and each of them (with full power to act without the other), as the undersigned’s true and lawful attorneys-in-fact and agents, with full power and authority to act in any and all capacities for and in the name, place and stead of the undersigned in connection with the filing with the Securities and Exchange Commission (the “SEC”) pursuant to the Securities Act of 1933, as amended (the “Securities Act”), of any amendment to this registration statement, with all exhibits thereto, and all other documents in connection therewith, and all amendments (including post-effective amendments) thereto pertaining to offerings by The Cigna Group of debt securities, preferred stock, common stock and, to the extent included in such registration statement, warrants, purchase contracts and units that may include any of the above securities or securities of other entities, or any combination thereof, including, without limitation, a registration statement on Form S-3 and a registration statement under Rule 415 of the Securities Act.

Such attorneys-in-fact and agents, or any of them, are also hereby granted full power and authority, on behalf of and in the name, place and stead of the undersigned, to execute and deliver all such registration statements, registrations, amendments, exhibits, qualifications and notifications, and to execute and deliver any and all such other documents, and to take further action as they, or any of them, deem appropriate. The powers and authorities granted herein to such attorneys in-fact and agents, and each of them, also include the full right, power and authority to effect necessary or appropriate substitutions or revocations. The undersigned hereby ratifies, confirms, and adopts, as his or her own act and deed, all action lawfully taken by such attorneys-in-fact and agents, or any of them, or by their respective substitutes, pursuant to the powers and authorities herein granted.

Pursuant to the requirements of the Securities Act, this registration statement has been signed by the following persons in the capacities indicated as of September 2, 2025.
