Chevron on Friday posted a $6.6 billion loss in the fourth quarter due to $10.4 billion worth of write-offs related to shale gas production in Appalachia and deep-water projects in the Gulf of Mexico. In December, the company warned that this charge would be $10 billion to $11 billion.



Shares slid 3.85% on Friday after the company reported $36.35 billion in revenue for the period, which missed analyst expectations and was down 14% year over year, hurt by weakness in the company's upstream division.

Chevron said it earned $1.49 per share excluding items, down from $1.95 per share a year earlier.

Here's how the energy giant's results fared on an adjusted basis relative to Wall Street expectations:

Adjusted earnings: $1.49 cents per share vs. $1.45 expected by a Refinitiv survey of analysts

Revenue: $36.35 billion vs. $38.639 billion expected by Refinitiv

A year earlier, the company earned $3.7 billion. Total earnings for 2019 slid 80%, to $2.924 billion, compared with $14.824 billion in 2018.

Oil-equivalent production at 3.08 million barrels per day was unchanged year over year, although the company said its annual daily production exceeded 3 million barrels per day for the first time.

The company's upstream operations in the U.S. lost $7.5 billion in the quarter, down from earnings of $964 million a year earlier. That was primarily due to $8.2 billion in write-offs related to Appalachia and Gulf of Mexico operations, as well as lower crude and natural gas prices.
