C.H. Robinson's chief executive, Bob Biesterfeld, resigned on Saturday in what the company called an "involuntary termination by the company without cause" in a federal filing.
The company's board chair, Scott Anderson, is now interim CEO, the company said on Tuesday.
The Eden Prairie-based company offered no reason for the abrupt transition with its public announcement Tuesday morning. The logistics and freight giant has retained Russell Reynolds, a leading national executive search firm, to find a permanent replacement.
Jack Atkins, an analyst with Stephens Inc., said pressure on the company's top leader has been increasing for a while.
"Our sense is that this transition has been building in recent months," Atkins wrote in a note to investors on Tuesday.
The company's fall has been bumpy as the supply chain disruption of the pandemic settles into a new normal. C.H. Robinson announced in November it would lay off 650 workers, or 3.6% of its workforce, after sagging third quarter results.
Biesterfeld said in July the company would see lower demand from rising inflation rates and changes in consumer habits. Slowing retail and housing markets, he said, would slow demand in the second half of the year.
"It has been a privilege to lead C.H. Robinson and this exceptional team," Biesterfeld said in a news release. "I am proud of all that we have achieved together, and it has been a pleasure working with so many talented members of the team throughout the organization during my tenure as CEO. I am confident that C.H. Robinson's industry leading people and culture will continue to ensure that the company is well-positioned for the future."
