* Accounting disclosure is less useful information, many numbers are disclosed grouped, rather than separately for each business.  The complexity of a conglomerate's accounts makes it harder for managers, investors, and regulators to analyze and makes it easier for management to hide issues.
* 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.<ref>{{cite news| url=http://news.bbc.co.uk/2/hi/business/607338.stm| title=Culture clash: The risks of mergers| date=January 17, 2000| work=BBC News| url-status=live| archive-url=https://web.archive.org/web/20090602063140/http://news.bbc.co.uk/2/hi/business/607338.stm| archive-date=June 2, 2009}}</ref><ref>{{cite journal| title=Surviving Post-merger 'Culture Clash': Can Cultural Leadership Lessen the Casualties?| author=Michelle C.

* [[Brand#Brand extension and brand dilution|Brand dilution]] where the brand loses its brand associations with a market segment, product area, or quality, price, or cachet.
* Conglomerates more easily run the risk of being [[too big to fail]].

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.<ref>{{cite web |url=http://www.investopedia.com/terms/c/conglomeratediscount.asp |title=Conglomerate Discount |access-date=2015-03-31 |url-status=live |archive-url=https://web.archive.org/web/20150330060326/http://www.investopedia.com/terms/c/conglomeratediscount.asp |archive-date=2015-03-30 }}</ref>
