SPLIT-OFF EXCHANGE OFFER FOR FORTIVE’S AUTOMATION AND SPECIALTY BUSINESS

On August 28, 2018, Fortive commenced an exchange offer related to the split-off of its automation and specialty platform (excluding Fortive’s Hengstler and Dynapar businesses) (the “A&S Business”). The split-off is in connection with Fortive’s announcement on March 7, 2018, that Fortive will separate its A&S Business and then combine it with Altra Industrial Motion Corp. (“Altra”). The terms of the transaction call for Fortive to separate its A&S Business through the split-off of its subsidiary, Stevens Holding Company, Inc., and to immediately merge Stevens Holding Company, Inc. with a subsidiary of Altra. Fortive will provide indicative calculated per share values and exchange ratios for each of the trading days that the exchange offer is open. The final exchange ratio is expected to be calculated using the volume weighted average stock prices (“VWAP”) of Fortive and Altra on September 19, 2018, September 20, 2018 and September 21, 2018, and is expected to be announced by 9:00 a.m., New York City time, on September 24, 2018, the second to last full trading day prior to the expiration date of the exchange offer, unless the exchange offer is extended or terminated. The exchange offer will expire at 8:00 a.m. on September 26, 2018, unless the offer is extended or terminated. Further information regarding the exchange offer can be found using the links below.

Table of Historical Indicative Calculated Per-Share Values

This table below shows VWAPs and historical indicative calculated per-share values for shares of Fortive common stock and shares of Altra common stock, and the corresponding indicative exchange ratio, beginning on the third trading day of the exchange offer period, calculated as though that day were the last Valuation Date of this exchange offer. On each day before the first Valuation Date commencing on the second trading day of the exchange offer, the information in the table will be updated by 4:30 p.m., New York City time, except that no indicative calculated per-share values or indicative exchange ratios will be provided for the first two trading days of the exchange offer period, as such values require daily VWAP data for three trading days.

During the first two Valuation Dates, when the values of Fortive common stock and Altra common stock are calculated for the purposes of the exchange offer, the website will provide indicative exchange ratios that will be calculated based on the indicative per-share values using actual trading data, as calculated by Fortive based on data obtained from Bloomberg L.P., which will equal: (i) on the first Value Date, the daily VWAP of Fortive common stock and Altra common stock for that day; and (ii) on the second Valuation Date, the simple arithmetic mean of the daily VWAPs of Fortive common stock and the Altra common stock for the first and second Valuation Dates. The website will not provide an indicative exchange ratio on the third Value Date. During the first two Valuation Dates, the indicative exchange ratios and calculated per-share values will be updated at 4:30 p.m., New York City time. This information may reflect up to a 30-minute reporting and upload delay.

The final exchange ratio will be available by 9:00 a.m., New York City time, on the second to last full trading day prior to the expiration date of the Exchange Offer.
