9. The Mosaic Company (NYSE:MOS)

Shares of The Mosaic Company (NYSE:MOS) fell by 13.31 percent on Wednesday to end at $30.93 apiece as investors sold off positions after missing earnings estimates in the second quarter of the year.

The Mosaic Company (NYSE:MOS) registered a $411 million net income in the second quarter of the year, reversing a $162 million net loss in the same period last year, primarily driven by higher average selling prices across all segments.

“Mosaic’s second quarter 2025 performance reflects extensive maintenance activity and several discrete items. The work we completed in the first six months of the year sets the stage for a strong second half, supported by improved operating performance, reduced turnaround activity, our excellent execution in Brazil, and compelling fertilizer market fundamentals,” said The Mosaic Company (NYSE:MOS) President and CEO Bruce Bodine.
