Mosaic Slides as Fertilizer Weakness and a Quarterly Loss Keep Pressure on Shares


Mosaic enters Friday's trading session under renewed pressure after the fertilizer producer's shares fell sharply Thursday, extending a difficult stretch for one of the smaller companies in the S&P 500.

Shares of MOS closed Thursday at approximately $23.70, down about 2.8% for the session. The decline left the stock roughly 36% below its 52-week high near $37.

The weakness comes as investors continue to digest a difficult second quarter in which Mosaic reported lower revenue and swung from a substantial profit a year earlier to a net loss.

Second-quarter revenue totaled approximately $2.82 billion, down about 6% from $3.01 billion in the comparable period last year. The company recorded a GAAP net loss of roughly $273 million, or $0.86 per diluted share, compared with net income of $411 million, or $1.29 per share, one year earlier.

On an adjusted basis, the picture was somewhat better. Mosaic earned $0.13 per share, exceeding the roughly $0.09 consensus estimate. However, the earnings beat was overshadowed by revenue that fell short of expectations and continued concerns about fertilizer volumes and margins.

The contrast helps explain the uncertainty surrounding MOS. Investors are weighing the company's ability to control costs against a fertilizer market in which pricing, demand and raw-material expenses can change rapidly.

Mosaic is one of the world's major producers of phosphate and potash fertilizers. Those nutrients are essential for crop production, giving the company direct exposure to global agriculture, planting activity, crop prices and farmer economics.

That exposure can produce substantial profits when fertilizer supplies are tight and prices are elevated, but it can work in the opposite direction when demand weakens or additional supply enters the market. Recent volatility in the global fertilizer trade has made that cycle especially important for shareholders.

Potash has attracted additional attention this week following discussion of increased U.S. purchases from Belarus. The prospect of additional lower-cost supply entering the market has raised concerns about pricing for North American fertilizer producers and contributed to volatility across the sector.

For MOS, weaker fertilizer prices would be particularly important because even relatively small changes in realized pricing can have a meaningful effect on profitability across large production volumes.

The company also faces cost pressures in its phosphate operations. Producing phosphate fertilizer requires several important inputs, including sulfur and ammonia, and changes in those costs can significantly affect margins even when finished-product prices remain relatively stable.

Despite the difficult earnings environment, Mosaic continues returning cash to shareholders. The company recently declared a quarterly dividend of $0.22 per share, which was paid September 24 to shareholders of record as of September 10.

That payment translates to an annualized dividend of $0.88 per share. At the stock's recent price, the indicated yield is approximately 3.7%, giving shareholders an income component while they wait to see whether fertilizer-market conditions improve.

The stock's valuation has also changed considerably as the shares have declined. With a market capitalization of roughly $7.5 billion, MOS now sits near the smaller end of the S&P 500 by market value.

Trading activity has remained elevated. More than nine million shares changed hands Thursday as the stock traded between approximately $23.18 and $24.43, suggesting investors remain actively divided over the outlook for the fertilizer producer.

The company's next quarterly report will provide an important test. Investors will be looking closely at phosphate and potash sales volumes, realized fertilizer prices, raw-material expenses and management's expectations for agricultural demand heading into the next planting cycles.

For MOS, the central question is whether the current weakness represents another leg down in the fertilizer cycle or a period of depressed profitability that eventually gives way to tighter supplies and improving margins. With the shares substantially below their year-ago high, the market is currently assigning considerable weight to the risks.
