NEW YORK (TheStreet) -- Shares of Mosaic (MOS) - Get Mosaic Company (MOS) Report were slumping in late-morning trading on Wednesday as Vertical Research cut its rating on the stock to "sell" from "hold," the Fly reports.

The firm now sees 24% total downside to its $22 price target, including the 3.6% dividend.

Vertical Research also expects a potential Agrium (AGU) and Potash (POT) merger to pressure Mosaic's domestic potash shipments, the Fly noted.

Yesterday, Mosaic stock spiked after Agrium confirmed it was in preliminary discussions about combining with Potash.

Mosaic is a Plymouth, MN-based producer and marketer of concentrated phosphate and potash crop nutrients.

But the team also finds weaknesses including deteriorating net income, disappointing return on equity and poor profit margins.
