Johnson Controls is the latest member of corporate America to weigh a breakup as the best move for its shareholders.

The company, a giant industrial parts conglomerate based in Milwaukee, said on Wednesday that it was considering spinning off or selling its auto parts business to focus on other divisions like its air-conditioning operations.

The announcement followed moves by other big American corporations to break themselves apart, as Wall Street shows a fondness for leaner, more focused companies. Stalwarts like General Electric and Hewlett-Packard have spun off or said they would spin off often slower-growing divisions into separate publicly traded companies, arguing that doing so gives each business more clarity and operating focus.

For Johnson Controls, parting with its automotive business, which manufactures seating and other interior parts for cars, would remove a division that generated about $22 billion in sales in its 2014 fiscal year, or more than half of its yearly revenue.
