WellPoint Announces Early Results, Increase to Tender Cap and Pricing of Its Previously Announced Tender Offers

Indianapolis, Ind., August 13, 2013 – WellPoint, Inc. (“WellPoint”) announced today the early results and pricing for its previously announced cash tender offers for $600 million aggregate principal amount of its outstanding notes, in each case at a purchase price determined in accordance with the procedures of a modified “Dutch Auction.” The offers (the “Offers”, and each an “Offer”) are comprised of:

As of 5:00 p.m., New York City time, on August 12, 2013 (the “Early Tender Time”), WellPoint had received early tenders for approximately (i) $580.0 million aggregate principal amount of First Tranche Notes, and (ii) $802.8 million aggregate principal amount of Second Tranche Notes, as specified in the table below. Each of the First Tranche Notes and Second Tranche Notes validly tendered (and not validly withdrawn) exceeds the previously announced Tender Caps. In addition, WellPoint announced that it is raising the Tender Cap for the Second Tranche Notes from $300 million to $400 million, which is the maximum increase previously contemplated and described in the Offer Documents. Because the aggregate principal amounts of each of the First Tranche Notes and Second Tranche Notes validly tendered (and not validly withdrawn) pursuant to the Offers exceed the applicable Tender Caps, as increased, each of the tendered First Tranche Notes and Second Tranche Notes have been accepted for purchase on a prorated basis as provided in the Offer Documents. As a result, WellPoint has accepted for purchase $300.0 million aggregate principal amount of the First Tranche Notes and $400.0 million aggregate principal amount of the Second Tranche Notes.

Holders of Notes validly tendered (and not validly withdrawn) at or prior to the Early Tender Time and accepted for purchase are eligible to receive the “Full Tender Offer Consideration” specified in the table below, which includes the Early Tender Payment (as defined in the Offer Documents). In addition to the Full Tender Offer Consideration, Holders of Notes accepted for purchase will receive Accrued Interest (as defined in the Offer Documents) on those Notes from the last interest payment date with respect to those Notes to, but not including, the Early Settlement Date (as defined in the Offer Documents). Since each of the Offers was oversubscribed as of the Early Tender Time, WellPoint will not accept for purchase any Notes tendered after the Early Tender Time. Furthermore, the withdrawal deadline of 5:00 p.m., New York City time, on August 12, 2013 has passed and has not been extended.

WellPoint expects to settle all Notes shown as accepted in the table above on August 13, 2013. All Notes not accepted by WellPoint as a result of proration will be rejected and returned to Holders.

The Offers are described in the Offers to Purchase dated July 30, 2013 and the related Letter of Transmittal dated July 30, 2013, as amended by the press release issued by WellPoint on August 6, 2013 (together, the “Offer Documents”), previously sent to holders of the Notes. Capitalized terms used in this press release and not defined herein have the meanings given to them in the Offer Documents. Except as described above, the Offers are not modified by this announcement.

THE OFFERS TO PURCHASE ARE BEING MADE SOLELY PURSUANT TO THE OFFER DOCUMENTS, WHICH SET FORTH THE COMPLETE TERMS OF THE OFFERS THAT HOLDERS OF THE NOTES SHOULD CAREFULLY READ PRIOR TO MAKING ANY DECISION.

THE OFFER DOCUMENTS DO NOT CONSTITUTE AN OFFER OR SOLICITATION TO PURCHASE NOTES IN ANY JURISDICTION IN WHICH, OR TO OR FROM ANY PERSON TO OR FROM WHOM, IT IS UNLAWFUL TO MAKE SUCH OFFER OR SOLICITATION UNDER APPLICABLE SECURITIES OR BLUE SKY LAWS. IN ANY JURISDICTION IN WHICH THE SECURITIES, BLUE SKY OR OTHER LAWS REQUIRE THE OFFERS TO BE MADE BY A LICENSED BROKER OR DEALER, THE OFFERS WILL BE DEEMED TO BE MADE ON BEHALF OF THE OFFEROR BY ANY OR ALL DEALER MANAGERS, IF ONE OR MORE OF THE DEALER MANAGERS ARE LICENSED BROKERS OR DEALERS UNDER THE LAWS OF SUCH JURISDICTION, OR BY ONE OR MORE REGISTERED BROKERS OR DEALERS THAT ARE LICENSED UNDER THE LAWS OF SUCH JURISDICTION.

NEITHER THIS PRESS RELEASE NOR THE OFFER DOCUMENTS CONSTITUTE AN OFFER TO SELL OR SOLICITATION OF AN OFFER TO PURCHASE WITH RESPECT TO ANY DEBT SECURITIES, NOR SHALL THERE BE ANY SALE OF SECURITIES IN ANY STATE OR JURISDICTION IN WHICH SUCH OFFER, SOLICITATION OR PURCHASE WOULD BE UNLAWFUL PRIOR TO THE REGISTRATION OR QUALIFICATION UNDER THE SECURITIES LAWS OF ANY SUCH JURISDICTION.
