WellPoint Launches Cash Tender Offers for $600 Million Aggregate Principal Amount of Outstanding Notes

Indianapolis, Ind., July 30, 2013 –WellPoint, Inc. (“WellPoint”) announced today the commencement of 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”) will be comprised of:

WellPoint also announced today the launch of its public offering of its 5-year and 30-year notes (the “New Notes”). The New Notes offering is expected to close on or about August 6, 2013, subject to customary closing conditions. Each Offer is conditioned on the closing and issuance of the New Notes yielding gross proceeds to us of at least the aggregate amount of the Tender Caps, which condition may be waived, with respect to either Offer, at our option.

The terms and conditions of the Offers are described in the offer to purchase dated July 30, 2013 (the “Offer to Purchase”) and the related letter of transmittal (the “Letter of Transmittal” and, together with the Offer to Purchase, the “Offer Documents”).

The Offers will expire at 11:59 p.m., New York City time, on August 26, 2013, unless extended or earlier terminated by WellPoint (such date and time with respect to an Offer, as the same may be extended or earlier terminated, the “Expiration Time”). Holders must validly tender and not properly withdraw their Notes at or prior to 5:00 p.m., New York City time, on August 12, 2013, unless extended by WellPoint (such date and time with respect to an Offer, the “Early Tender Time”), in order to be eligible to receive the applicable Full Tender Offer Consideration (defined below), which includes the applicable early tender payment set forth in the table above (the “Early Tender Payment”). Holders that validly tender their Notes after the applicable Early Tender Time and at or prior to the applicable Expiration Time for an Offer will not be eligible to receive the Early Tender Payment and will only be eligible to receive the applicable Late Tender Offer Consideration. The price determination time for the Offers will be 11:00 a.m., New York City time, on August 12, 2013, unless extended by WellPoint. In each case, Holders that validly tender Notes that are accepted for purchase by WellPoint will receive accrued and unpaid interest from, and including, the last interest payment date to, but not including, the Settlement Date for such Notes, in each case rounded to the nearest cent (“Accrued Interest”). Notes validly tendered may be withdrawn at any time on or prior to 5:00 p.m., New York City time, on August 12, 2013, unless extended by WellPoint (such date and time with respect to an Offer, as the same may be extended, the “Withdrawal Deadline”), but not thereafter.

Acceptance of Notes with respect to each Offer is subject to proration if such Offer is oversubscribed. If any Notes are purchased in an Offer, Notes tendered at or prior to the applicable Early Tender Time will be accepted for purchase in priority to other Notes tendered in the same Offer after the applicable Early Tender Time. Accordingly, if the First Tranche Tender Cap or Second Tranche Tender Cap is reached in respect of tenders made at or prior to the applicable Early Tender Time, no First Tranche Notes or Second Tranche Notes, respectively, that are tendered after the applicable Early Tender Time will be accepted for purchase.

Following the applicable Early Tender Time and prior to the applicable Expiration Time, WellPoint may, but is not obligated to, with respect to any Offer, elect to accept the Notes validly tendered at or prior to the applicable Early Tender Time, provided that all conditions to such Offer have been satisfied or waived by WellPoint and settle such Notes at such time or promptly thereafter (such date of settlement with respect to an Offer, the “Early Settlement Date”). The “Final Settlement Date” with respect to an Offer is the date that WellPoint settles all Notes not previously settled on the applicable Early Settlement Date, if any, and WellPoint expects such date to be one business day following the applicable Expiration Time. The Early Settlement Date is expected to be August 13, 2013, and the Final Settlement Date is expected to be August 27, 2013, in each case subject to change without notice. WellPoint refers to each of the Early Settlement Date and the Final Settlement Date as a “Settlement Date.”
