Georgia-Pacific is getting a new president and CEO, the company announced Wednesday.
Christian Fischer, who has served as president and CEO since 2017, will retire from the company at the end of October, ending a tenure dating back to 1989. Beginning in August, he will transition his responsibilities to Mark Luetters, who is currently an executive vice president at Koch.

Georgia-Pacific has been a subsidiary of Koch for the past 20 years. Luetters has overseen Georgia-Pacific during that period, and spent nearly a decade as president of GP Building Products.
Luetters will serve as an interim replacement. Georgia-Pacific expects to name a more permanent leader next year.
“I look forward to working collaboratively with the GP team on our key initiatives, and ultimately naming a new, long-term GP president and CEO at some point within calendar year 2026,” Luetters said in a statement.
In another leadership change earlier this year, Georgia-Pacific named Keith Hamilton the new president of its corrugated business.
Georgia-Pacific, one of the largest producers of containerboard and corrugated packaging, announced in May that it would permanently close a containerboard mill in Cedar Springs, Georgia, resulting in 535 planned layoffs, most to take place by Aug. 1. The company indicated production may move to containerboard mills in Alabama, Mississippi, Oregon and Virginia.
