NEW YORK — General Electric has long been a household name, manufacturing a spectrum of goods from light bulbs and air conditioners to MRI machines and jet engines. The company expanded rapidly in the 1980s under former CEO Jack Welch, accumulating financial companies and the television network NBC.

But the sprawling company’s broad reach has left it vulnerable to market shifts in many industries, and the financial crisis hurt GE badly.

Those vulnerabilities led GE to announce in June that it would shed its health care business and sell its interest in Baker Hughes, which provides drilling services to oil and gas companies, moves analysts applauded as a hopeful sign that GE would narrow its focus.

“There are too many lines of business,” said Josh Aguilar, equity analyst from Morningstar. “They tried to do too many things for too many people.”

POWER

GE’s power division is its largest, but its foundation has been shaken by the changing ways people use energy. Demand for gas turbines — a core part of GE’s power business — is falling as consumers reduce energy use and switch to renewables.

Instead of reigning it in during shifting demands for its product, GE bought France-based Alstom’s power and grid business, a $10 billion move some analysts say was made in part to keep Alstom out of the hands of competitors.

AVIATION

Aviation is the most profitable part of GE’s business. The company produces jet engines, aerospace systems, replacement parts and maintenance services for commercial, executive and military aircraft.

“The bright spot for GE has been aviation by far,” Aguilar said.

HEALTH CARE

GE’s health care unit — its third-largest segment — produces diagnostic imaging systems including magnetic resonance, X-ray, digital mammography and nuclear imaging. The business has been relatively stable, but former CEO John Flannery had planned to spin off the unit in 2019, a move that analysts saw as an important step toward reducing the company’s debt load as it transfers debt and pension liabilities to the separated company. GE CEO Larry Culp indicated he intends to follow through with those plans.

CAPITAL

Seen by some as the “black hole” of GE, the capital business — which includes commercial loans and leases, fleet management, credit cards and personal loans — is facing a pair of investigations. The Securities and Exchange Commission is looking into how GE took a $15 billion hit after a subsidiary miscalculated how much it would cost to pay for the care of people who lived longer than projected.

GE also said the Justice Department may take action in connection to an investigation into the company’s subprime mortgage loans business.
