Inch said there are "a lot of parties that are culpable here."
"The information they provided was one-sided. They made it overly complicated to dissect the financials. They compounded the complexity on purpose so people wouldn't look at the details," he added. "Now unfortunately they're paying a bit of a price for it."
A GE spokesperson told CNBC, "Mr. Inch's assertion is factually incorrect. As we've said, we follow rigorous accounting practices, in line with GAAP guidelines. Any statement or suggestion otherwise is false and misleading."
Shares of GE have been on a downward slide, dropping 40 percent since Immelt stepped down in October.
Among the problems plaguing the company is a collapse in cash flow and a severely curtailed profit outlook, Inch said. He also thinks the dividend, which was cut in half in November, is at risk of being slashed again.
"We could be facing a multiyear power [generation industry] downturn when just less than a year ago the company was going full throttle, talking about how great everything was. And today the world looks completely different," he said.
Inch, who has a sell rating on GE and a $13 price target, also thinks the notion of a GE breakup was put out as a "deflection" from the company's "fairly serious challenges."
CNBC reported last month that the company is aiming to announce a decision on breaking up its businesses as early as this spring, according to sources. A split is likely, the sources said.
"The reality is GE cannot separate. It's on the hook to back 100 percent of GE's Capital's bonds. It has over $30 billion of underfunded liability," he said.
On top of that, the Securities and Exchange Commission is investigating the company's accounting and the Justice Department is probing GE's ownership of a subprime mortgage company it owned before the financial crisis, Inch added
"You can't just separate the company. You'd have to refinance $150 billion of bonds plus untold incalculable liability. It's just not going to work. It's a nice narrative. It's just not possible."
A spokesperson for Immelt did not immediately respond to a request for comment on Inch's remarks.
