Conglomerate (company) - Disadvantages

Disadvantages

• The extra layers of management increase costs.
• Accounting disclosure is less useful information, many numbers are disclosed grouped, rather than separately for each business. The complexity of a conglomerate's accounts make them harder for managers, investors and regulators to analyze, and makes it easier for management to hide things.
• Conglomerates can trade at a discount to the overall individual value of their businesses because investors can achieve diversification on their own simply by purchasing multiple stocks. The whole is often worth less than the sum of its parts.
• Culture clashes can destroy value.
• Inertia prevents development of innovation.
• Lack of focus, and inability to manage unrelated businesses equally well.

Some cite the decreased cost of conglomerate stock (a phenomenon known as conglomerate discount) as evidential of these disadvantages, while other traders believe this tendency to be a market inefficiency, which undervalues the true strength of these stocks.
