Robert Hansberger of Boise Payette became the CEO, and the new corporation focused on ownership and management of timberlands, the growing and harvesting of timber, and the manufacturing and distribution of lumber products and building materials.

The mid-1960s brought an even more diverse portfolio including ownership of a motor home manufacturer, a cruise line, involvement in real estate and recreation projects, and an acquisition in the engineering and construction business for major utilities.

Boise native William Agee joined the company in 1964 and was the chief financial officer from 1969 to May 1972;[5][6] the stock price rapidly rose to $77 in 1969, but was down to $15 by the fall of 1971.

With the share price at around eleven dollars, Hansberger resigned in October 1972;[9][10] John Fery was promoted to CEO and moved the company back to its core competencies of building materials and paper products.

[11][12] As the 1980s progressed, a decline in the housing market led to a downsizing in building products distribution business, and by 1987, all retail outlets had been sold or closed.

In the 1990s, Boise Cascade invested in engineered wood products, building mills in White City, Oregon, and in Alexandria, Louisiana, for producing laminated veneer lumber (LVL).

In 1999, Furman Lumber of Billerica, Massachusetts, was purchased, which led to a nationwide building material wholesale distribution system for Boise Cascade.

In 2004, Madison Dearborn Capital Partners purchased the paper, forest products and timberland assets and created a privately owned company called Boise Cascade LLC.

Tom Carlile assumed the position of CEO in 2009, and began to lead the company through the slow housing recovery with investments in EWP and veneer facilities and the building materials distribution footprint.
