(Updated profit vs. concensus estimate and analyst comments; updated premarket trading>)General Electric ( GE) saw its quarterly earnings from continuing operations drop by 47% from its second quarter last year, due to big declines in its capital finance unit and NBC Universal. GE earned $2.9 billion from continuing operations, or 26 cents a share. Its strongest segment was Energy Infrastructure, in which revenue grew by 13% from last year's second quarter. But Capital Finance saw an 80% sales drop and NBCU revenue fell by 40%. The results beat the consensus estimate of analysts polled by Thomas Reuters, which had estimated earnings of 23 cents a share. Analyst Terry Darling of Goldman Sachs wrote, "strong share price performance over the last several days likely limits upside, with ongoing regulatory uncertainty still a key overhang." GE touted what it said was a record backlog of $122 billion in contractual service orders and said the $7.1 billion cash flow in its industrial unit is ahead of a plan it laid out for investors earlier in the year. "In a global economic environment that continues to remain challenging, GE delivered solid second-quarter business results," GE Chairman and CEO Jeff Immelt said. GE shares were losing 3.4% to $11.98 in recent premarket trading.
