I mean the logic of capitalism dictates that companies have to keep making profit, and for any companies traded on the market that means showing constant quarterly growth to shareholders. This makes it very difficult to make a fundamental pivot in the business model that would be needed to switch from extracting fossil fuels to building renewables. It would require setting up supply chains, building factories, training workers, etc. At the same time their current investments into mining equipment, land, and so on lose value. All of these are astronomical expenses these companies simply can't justify doing. Capitalist realities favor short term planning.
