The last few years have certainly not been kind to General Electric (GE). The multinational conglomerate came in as the worst performing stock on the Dow Jones Industrial Average in 2017, only to be replaced on the index by Walgreens Boots Alliance Inc. less than a year later in June 2018. As the conglomerate struggles to turnaround by restructuring verticals, spinning-off companies, and selling-off business lines, investor confidence remains low and the company's stock price continues to head south.

On November 6, 2018, General Electric announced the latest of its subsidiary selloffs. According to the Wall Street Journal, General Electric has agreed to sell Current, a GE subsidiary that produces energy management systems, to American Industrial Partners (AIP) for an undisclosed amount. Boston-based start-up Current was established by General Electric on October 7, 2015 with a revenue of approximately $1 billion.

Here are the leading subsidiaries that GE continues to own.

GE Power

The former bedrock of General Electric, GE Power is a wholly-owned subsidiary and remains the company's largest business division. GE Power produces systems that generate power using wind, oil, gas, and water, but the subsidiary has taken a sharp downturn in recent years, especially after the sale of GE Capital and the refocusing of General Electric's core business segments. General Electric reported third-quarter revenues of $29.6 billion on October 30, 2018. GE Power accounted for $5.74 billion of General Electric's revenues this quarter, down 33.8% from $8.67 billion over the same period last year.

GE Aviation

One of General Electric's few business segments with consistent growth, GE Aviation provides jets, turboprop engines, and designs software used by major aviation corporations. The segment has plans to have 60,000 jet engines connected to the internet by 2020, which they claim will save fuel and create fewer delays at airports. GE Aviation grew to $7.48 billion in revenues in Q3 2018, up from $6.82 billion over the same period last year.

GE Renewable Energy

GE Renewable Energy, also known as GE Energy Connections, is the company's energy management division focused on the distribution, conversion, automation, and optimization of energy sources. By focusing on an area that promotes sustainability and increased efficiency, there is plenty of room to grow. With $2.88 billion in revenues for Q3 2018, compared to $2.90 billion last year, GE Renewable Energy is one of the companies smallest, but more reliable, business segments.

GE Oil & Gas

GE Energy was divided into three subsidiaries: GE Power, GE Energy Connections, and GE Oil & Gas. The latter of these subsidiaries is the fourth-largest revenue generator for General Electric, producing smart and efficient solutions to the oil and gas industry. Parent company General Electric is betting that better efficiency in production is what most producers want — and that bet may just pay off. In Q3 2018, GE Oil & Gas accounted for $5.67 billion of General Electric's quarterly revenues, up from $5.37 billion the year before.
