The News-Review reports Sierra Pacific Industries announced last week it had completed the acquisition. The combination of the two companies means Sierra Pacific Industries will have than 2.3 million acres of timberlands, 18 sawmills and eight renewable biomass energy cogeneration facilities, along with millwork and windows operations.
