NEW YORK (TheStreet) -- Southwestern Energy (SWN) - Get Report stock is plummeting 18.76% to $5.50 on heavy volume in afternoon trading on Friday following the release of its 2015 fourth quarter earnings and a ratings downgrade at Jefferies. 

After yesterday's market close, the natural gas and oil company reported an adjusted loss of 2 cents per share, narrower than the per-share loss of 4 cents anticipated by analysts. 

Operating revenue was $687 million for the quarter, below estimates for $782 million. 

Southwestern Energy separately reiterated its plan to temporarily halt drilling activities and noted that previous layoffs should save the company between $150 million and $175 million annually.

The company projects that it will spend between $350 million and $400 million on capital investments this year, down from $1.83 billion during 2015.

Following Southwestern Energy's financial release, Jefferies downgraded shares to "underperform" from "buy" and cut its price target to $4 from $11.

The firm cited "a much weaker than expected operational outlook causing us great concern about its financial condition, even with our bullish gas view." Jefferies added that Southwestern Energy expects 2016 fourth quarter production to fall "by a fairly staggering 27%."
