What happened 

Shares of materials company Rayonier Advanced Materials Inc (RYAM 3.44%) jumped as much as 11.8% in trading Thursday after announcing a major acquisition. At 3:30 p.m. EDT, the shares were holding at a 10.6% gain on the day.

So what

Rayonier announced it's buying Canadian-based lumber company Tembec Inc. for $807 million, including assumed debt. This will give Rayonier a more diverse product base in cellulose, packaging, paper, pulp, and other forest products.

The deal will have Rayonier offering $3.02 per share in cash to Tembec holders, or 0.2302 shares of Rayonier stock per share. But the deal will be prorated so 63% of the price will be paid in cash and 37% in stock. 

Now what

For Rayonier, the deal gives a more diverse product line and customer base that management says will generate about $2 billion in annual revenue and $400 million in earnings before interest, taxes, depreciation, and amortization (EBITDA). With the deal being offered at only 4.6 times EBITDA in the last 12 months, there could be significant upside for shareholders after management's expected synergies.

Time will tell if this acquisition pays off as planned, but for now, traders like what they see in Rayonier's growing business. If management can execute as planned it could pay off in spades.
