01:21 PM EDT, 09/25/2025 (MT Newswires) -- The shares of three fertilizer companies fell after the US reportedly initiated an antitrust review of crop input suppliers.

Intrepid Potash ( IPI ) shares fell 3.4% in recent Thursday trading, Mosaic (MOS) dropped 2.9%, and Nutrien ( NTR ) declined 2%.

The Department of Agriculture and the Department of Justice signed a memorandum of understanding to take a "hard" look into the competitive conditions in the agriculture market, Agriculture Secretary Brooke Rollins said at a conference in Missouri, Bloomberg reported.

The goal of the joint effort is to "protect American farmers and ranchers from the burdens imposed by high and volatile input costs, such as feed, fertilizer, fuel, seed, equipment and other essential goods," Rollins said at the Ag Outlook Forum in Kansas City, Reuters reported.
