Corteva, valued at $27 billion, became a publicly traded company last year after it was spun out of chemical giant DowDuPont. Starboard, which owns 11.7 million shares or 1.6% of Corteva, has said that the company has not lived up to its potential and is lagging behind its peers.

Corteva's board discussed Collins' future at a recent meeting and is fully supportive of him and management, the sources said, requesting anonymity because the matter is confidential.

A representative for Corteva declined to comment and Starboard did not return a call seeking comment.

Starboard CEO Jeffrey Smith has criticized Corteva's financial performance, noting that its cash flow margin of 14.4% lags behind peers, and that its share price, now at $36.96, could be closer to $55. The company's shares have climbed 44% in the last 52 weeks compared with a 14.35% in the S&P 500 Index.

Collins, who had previously been chief operating officer for the Agriculture Division of DowDuPont, was asked about performance on a quarterly earnings call earlier this month.

"We agree there is tremendous (cash flow) margin potential in this business. I don't have to go out and invent that future. It's sitting here right now. What we have to do is execute it," Collins said.

Investors will soon have a chance to nominate directors at Corteva.

Starboard is known for its operational know-how and often proposes to add new directors to a company's board. It won 17 board seats at four companies in the first half of 2020.
