"This essentially completes the announcement ... of our target of $20 billion of dispositions," Flannery said.

GE's second-quarter profit was 30 percent lower than last year, dragged lower by its power business and GE Capital – with the former reporting a 58 percent lower profit and and the latter posting a 20 percent greater loss. Reorganizing GE has been Flannery's push since he was appointed chief executive last August.

“We’ve described 2018 as a reset year and in this quarter we’ve made significant progress on that journey," CEO John Flannery said on a conference call with investors. "This is an execution story going forward."

General Electric will focus on meeting second half turnaround goals for its struggling power and GE Capital business units, the company said after its earnings report Friday.

General Electric Chief Executive Officer John Flannery presents the company's new strategy and financial targets to investors at a meeting in New York, November 13, 2017.

The power business is the company's number one focus for the remainder of 2018, CFO Jamie Miller told CNBC after the report, reiterating Flannery's comments on the call.

“Clearly our top priority is fixing the problems in the power business," Flannery said.

Power reported orders of of $7.4 billion, down 26 percent from a year ago. Revenues also declined 19 percent. Worst of all was the division's profit, down 58 percent from the same time last year. As it has before, GE said "softness" was the main culprit.

“The short term cycle is severe," Flannery said, adding that GE was "already working within the assumption of a very tough market.”

Still, Flannery said GE's power unit is "an asset that is worth protecting." A turnaround in power is going "to be a multiyear fix," Flannery said. He told shareholders that GE sees "a very clear plan of what we need to do" in power, again emphasizing the company's focus on the business.

Investors don’t seem to want to wait around, however, as GE stock dropped more than 4 percent in trading Friday, closing at $13.12 per share.

"GE is only at the outset of a multi-year effort to improve its fundamental financial performance," Moody's Investors Service vice president Rene Lipsch said in a note. CFRA Research analysts expressed similar expectations, saying GE's turnaround will "take a long time to play out."

GE Capital is the company's second battle after power. With $136 billion in assets, GE Capital produced a $206 million loss in the second quarter. GE is steadily decreasing the size of the business unit, planning to trim GE Capital assets by $25 billion before the end of 2019. Flannery says he is targeting GE Capital's earnings to "breakeven for the total year," after the unit reported a loss of 2 cents per share in the latest quarter.

"We continue to take out structural costs" from GE Capital and "are on track to exceed our goal of $2 billion" by the end of the year, Flannery said.

The risk of heavy penalties from the Department of Justice investigation of GE Capital continues to hang over the business. Miller said there was "really no change" in the second quarter from what GE has announced previously about the investigation. In the previous quarter, GE recorded reserves of $1.5 billion for potential liabilities from the DOJ investigation in connection with alleged subprime mortgage violations for GE Capital's now defunct WMC mortgage business.
