Shares of Milacron Holdings Corp. soared 21% toward a 9-month high in premarket trading Friday, after the plastic technology and processing company agreed to be acquired by Hillenbrand Inc. in a cash and stock deal valued at $2 billion. Meanwhile, Hillenbrand's stock tumbled 15% toward a 2 1/2-year low ahead of the open. Under terms of the deal, Milacron shareholders will receive $11.80 in cash and 0.1612 Hillenbrand shares for each Milacron share they own. Based on Thursday's stock closing prices, that values Milacron shares at $18.07 each, a 33.5% premium. Hillenbrand expects the deal, which is anticipated to close in the first quarter of 2020, to add to increase adjusted earnings in the "double-digit" range in the first year after closing, and deliver annualized cost synergies of about $50 million within three years. Hillenbrand's stock has gained 2.5% year to date through Thursday, while Milacron shares have rallied 14% and the S&P 500 has gained 20%.
