In addition, CVS Health announced that it has amended the terms of the Tender Offers to increase the Maximum Tender Offer Amount, namely the maximum aggregate principal amount of Maximum Tender Offer Notes that may be purchased in the Tender Offer therefor from $1,500,000,000 to $2,250,000,000. Other than the increase to the Maximum Tender Offer Amount, all other terms and conditions of the Tender Offers, as previously announced, remain unchanged. The Tender Offers are being made solely pursuant to CVS Health’s Offer to Purchase dated May 16, 2016 (the “Offer to Purchase”) and the related Letter of Transmittal, as amended by this press release.

As of 5:00 p.m., New York City time, on May 27, 2016 (the “Early Tender Date”), as reported by D.F. King & Co., Inc., the tender and information agent for the Tender Offers, the principal amounts of the Notes listed in the table below had been validly tendered and not validly withdrawn. The Withdrawal Deadline of 5:00 p.m., New York City time, on May 27, 2016 has passed and, accordingly, Notes validly tendered in the Tender Offers may no longer be withdrawn. The applicable Total Consideration per $1,000 principal amount of the Omnicare 2024 Notes and the Omnicare 2022 Notes will be the fixed amounts set forth in the table below. With regard to the other Notes, the table below also sets forth the applicable Reference Yield based on the bid-side price of the applicable UST Reference Security as displayed at 11:00 a.m., New York City time, on May 27, 2016 on the relevant Bloomberg reference page specified in the Offer to Purchase and Total Consideration payable for each $1,000 in principal amount of such Notes tendered and accepted for purchase pursuant to the Tender Offers.

Notes validly tendered and not withdrawn at or prior to the Early Tender Date and accepted for purchase will receive the applicable Total Consideration as set forth above, which includes the applicable Early Tender Payment of $30 per $1,000 principal amount of Notes tendered prior to the Early Tender Date and accepted for purchase.

Any and All Notes validly tendered and not withdrawn after the Early Tender Date and at or prior to 11:59 p.m., New York City time, on June 13, 2016 (such date and time, as may be extended, the “Expiration Date”) will be eligible to receive the applicable Tender Offer Consideration, which is the applicable Total Consideration less the applicable Early Tender Payment.

In addition to the Total Consideration or Tender Offer Consideration, as applicable, Holders of Notes accepted for purchase will receive accrued and unpaid interest on those Notes from the last interest payment date with respect to those Notes to, but not including, the Early Settlement Date or the Final Settlement Date (each as defined below).

CVS Health also announced its election, with respect to the Notes validly tendered and not validly withdrawn at or prior to the Early Tender Date, to accept for purchase and make payment for such Notes on May 31, 2016 (the “Early Settlement Date”), subject, in the case of the Maximum Tender Offer Notes, to the acceptance priority levels applicable to the relevant series and, in the case of the 3.875% Senior Notes due 2025, to proration as described in the Offer to Purchase. Because CVS Health has accepted for purchase the Maximum Tender Offer Amount of Maximum Tender Offer Notes, no additional Maximum Tender Offer Notes will be purchased pursuant to the Tender Offer for such Notes after the Early Settlement Date. Payment for the Any and All Notes validly tendered after the Early Tender Date and at or prior to the Expiration Date, will be made promptly following acceptance after the Expiration Date (the “Final Settlement Date”). The Final Settlement Date is expected to be on June 15, 2016.
