Oct 20 (Reuters) - General Electric Co on Friday reported a steep drop in profit, missing consensus estimates by 20 cents per share and sending its stock sharply lower in pre-market trading.
GE reported adjusted profit of 29 cents a share compared with the 49 cents a share analysts had expected, according to a consensus of estimates from Thomson Reuters I/B/E/S.
GE shares were down 4.6 percent at $22.50 in premarket trading.
GE said weak performance in its power and oil and gas businesses, goodwill impairment and higher-than-expected restructuring costs under new chief executive John Flannery were the main causes of the profit decline.
GE's "solid" performance in other businesses "was offset by a decline in power performance in a difficult market," Flannery said. Industrial cash flow from operations fell mainly "because of lower power volume, resulting in lower earnings and higher inventory.
Profit at GE's power business, which makes power plants and related equipment, fell 51 percent in the quarter.
Excluding items, industrial cash flows from operating activities was $1.74 billion in the third quarter ended Sept. 30, down from $2.90 billion, a year earlier.
The company reported a 14.4 percent rise in revenue to $33.47 billion, boosted by the acquisition of oilfield services provider Baker Hughes.
Unadjusted earnings per share from continuing operations fell to $1.80 billion, or 22 cents a share, from $1.99 billion, or 24 cents, the company said. (Reporting by Alwyn Scott in New York and Ankit Ajmera in Bengaluru; Editing by Martina D'Couto and Nick Zieminski)
