General Electric Co., which owns businesses ranging from light bulbs to NBC television, on Friday said it will restructure into four businesses from six, a move that Chief Executive Officer Jeff Immelt said will focus the company on growth. Immelt has been under pressure to shake up GE since it announced disappointing first-quarter earnings in April, shocking investors and pushing down its share price. The move follows GE's recent plan to consider spinning off its iconic lighting and appliance businesses, a brand familiar to generations of Americans. That appliance business is based in Louisville, Ky. The new structure includes: q GE Technology Infrastructure, which features Healthcare, Aviation, Transportation and Enterprise Solutions. q GE Energy Infrastructure, which includes Energy, Oil & Gas and Water. q GE Capital brings together all the financial service businesses including Commercial Finance, GE Money, industry verticals and Corporate Treasury. NBC Universal, headed by Jeff Zucker, will remain unchanged. In the reorganization, the GE units Commercial Finance, GE Money, GE Industrial and GE Healthcare have been folded into new, expanded business segments. The plan will improve GE Capital's opportunities.
