Fortive Announces Preliminary Results of Split-Off Exchange Offer in Connection with Altra Transaction

Everett, WA, September 26, 2018 – Fortive Corporation (NYSE: FTV) announced today the preliminary results of its exchange offer for Fortive common stock in connection with the previously announced separation of Fortive’s Automation and Specialty platform (excluding Fortive’s Hengstler and Dynapar businesses) (the “A&S Business”) and merger of Stevens Holding Company, Inc., the Fortive subsidiary holding its A&S Business (“Stevens Holding”), with a subsidiary of Altra Industrial Motion Corp. (NASDAQ: AIMC). Fortive intends to accept shares of Fortive common stock validly tendered in the exchange offer, subject to proration, and expects the closing of the merger to occur on October 1, 2018.

In the exchange offer, Fortive stockholders had the option to exchange some, none or all of their shares of Fortive common stock for shares of Stevens Holding common stock, subject to proration and with an exchange ratio of 2.2117 shares of Stevens Holding common stock for each share of Fortive common stock tendered and accepted for exchange. In the merger, each share of Stevens Holding common stock will be converted into the right to receive one share of Altra common stock (with cash in lieu of fractional shares).

Exchange Offer Results

Pursuant to the exchange offer, which expired at 8:00 a.m., New York City time, on September 26, 2018, and based on a preliminary count by the exchange agent, a total of approximately 128,941,860 shares of Fortive common stock were validly tendered and not properly withdrawn prior to the expiration of the exchange offer, including 61,048,910 shares tendered pursuant to guaranteed delivery procedures. The total number of shares tendered includes an estimated 1,044,987 shares of Fortive common stock tendered by odd-lot shareholders (excluding certain plan participants in Fortive savings plans) not subject to proration. Fortive will exchange a total of 15,824,931 shares of Fortive common stock in the exchange offer.

Based on the total number of shares of Fortive common stock reported to be tendered and not properly withdrawn prior to the expiration of the exchange offer, including shares tendered pursuant to guaranteed delivery procedures, the exchange offer was oversubscribed by approximately 113,116,929 shares, resulting in a preliminary proration factor of approximately 11.56 percent.

Fortive will not be able to determine the final proration factor until the end of the exchange offer’s guaranteed delivery period at 8:00 a.m., New York City time, on September 28, 2018. Fortive will publicly announce the final proration factor, which may be different from today’s preliminary estimate, after it has been determined.
