Thermo Fisher Scientific Announces Commencement of Cash Tender Offer for Convertible Notes and Redemption of Senior Notes

Thermo Fisher Scientific Inc. (NYSE: TMO), the world leader in serving science, announced today that it has commenced a tender offer to purchase for cash any and all of its outstanding 2.50% Convertible Senior Notes due 2023. The company also announced today that it has called for redemption all of its outstanding 6¾% Senior Subordinated Notes due 2014.

Tender Offer for Convertible Notes

The tender offer (the "Offer”) is being made upon the terms and subject to the conditions set forth in the company’s Offer to Purchase, dated November 13, 2009, and the related Letter of Transmittal. The Offer will expire at 12:00 midnight, New York City time, at the end of Thursday, December 17, 2009, unless it is extended or earlier terminated by the company (as may be extended by the company, the "Expiration Date”). As of November 12, 2009, there were Convertible Senior Notes ("Convertible Notes”) outstanding in an aggregate principal amount of $295,360,000.

Upon the terms and subject to the conditions of the Offer, holders of Convertible Notes who validly tender and do not validly withdraw their Convertible Notes prior to 12:00 midnight, New York City time, at the end of the Expiration Date, will receive, for each $1,000 principal amount of such Convertible Notes, a cash purchase price equal to (i) the Average VWAP (as defined below) multiplied by 42.1372 (which is the number of shares of the company’s common stock currently issuable upon conversion of $1,000 principal amount of Convertible Notes) plus (ii) a fixed cash amount of $56.50, provided that in no event will the purchase price per $1,000 principal amount of such Convertible Notes be less than $1,474.8020. In addition, holders will receive, in respect of their Convertible Notes that are accepted for purchase, accrued and unpaid interest on such Convertible Notes to, but excluding, the settlement date of the Offer. All amounts payable pursuant to the Offer will be rounded to the nearest cent.

"Average VWAP” is the arithmetic average of the "Daily VWAP” on each trading day during the period of 21 consecutive trading days ending on the Expiration Date. The Daily VWAP for any trading day means the per share volume-weighted average price of the company’s common stock on the New York Stock Exchange, as displayed under the heading "Bloomberg VWAP” on Bloomberg page TMO.N <Equity> AQR (or its equivalent successor if such page is not available), in respect of the period from scheduled open of trading until the scheduled close of trading of the primary trading session of the New York Stock Exchange on such trading day. If such volume-weighted average price is unavailable for any trading day, the Daily VWAP for such trading day will be the market value of one share of the company’s common stock on such trading day determined, using a volume-weighted average method, by a nationally recognized independent investment banking firm retained for this purpose by the company. The Daily VWAP will be determined without regard to after hours trading or any other trading outside of the regular trading session trading hours.

The company will determine the final purchase price promptly after the close of trading on the New York Stock Exchange on the Expiration Date and announce the final purchase price no later than 4:30 p.m., New York City time, on the Expiration Date. The final purchase price will also be available by that time at http://www.gbsc-usa.com/Thermo_Fisher and from the information agent for the Offer. Prior to the determination of the final purchase price, an indicative purchase price will be available at that same Web address and from the information agent for the Offer.

The terms and conditions of the Offer appear in the Offer to Purchase and the Letter of Transmittal, both of which will be distributed to all holders of the Convertible Notes. The Offer is not subject to any minimum tender or financing condition. However, the Offer is subject to certain other conditions, as more fully described in the Offer to Purchase. The company expressly reserves the right to waive these conditions in whole or in part at any or at various times in its sole discretion.
