Jan 29 (Reuters) - Lockheed Martin Corp reported a net loss in the fourth quarter on Monday as the U.S. defense contractor took a $1.9 billion charge mainly due to the change in U.S. tax law, but beat expectations for sales.
Lockheed said it expects 2018 net sales in the range of $50.00 billion-$51.50 billion and earnings per share of $15.20-$15.50.
Net sales rose to $15.14 billion from $13.75 billion a year earlier compared with the average analyst estimate of $14.72 billion. (Reporting by Ankit Ajmera in Bengaluru; Editing by Arun Koyyur)
