There is a growing call from investors for companies to present a clear picture of their operations as factors like climate change become a cornerstone of investment decision making. The effects of the COVID-19 pandemic have added to the pressure.
"I think there's definitely a strong tolling of the bell for conglomerates," William Blair & Company analyst Nicholas Heymann said.
GE said on Tuesday that it will split into three public companies seeking to simplify its business, pare down debt and breathe life into a battered share price.
The move could embolden the boards of several other multi-industry companies, such as Emerson Electric Co, Roper Technologies Inc and 3M, to move ahead on more aggressive portfolio simplification moves, RBC Capital Markets analyst Deane Dray said.
3M declined to comment. Roper and Emerson did not immediately respond to a request for comment.
"The simple reality is that companies are permissioned to conglomerate so long as they promise to de-conglomerate as soon as the prior strategy stops working," Scott Davis, an analyst at Melius Research said.
Davis also pointed out that complete or partial breakups have been successful for companies like Illinois Tool Works and Honeywell International Inc.
Citigroup analyst Martin Wilkie said GE's proposed split could heap the pressure on rival Siemens AG to become leaner.
Siemens last year spun-off its turbine business Siemens Energy, a move to help it transform itself to a more focused industrial technology company.
