It''s no secret that cement companies continually struggle to generate returns on invested capital (ROIC) greater than their cost of capital. (See "The cement industry at a turning point," on, December 2015.)That chronic underperformance stems in part from structural factors such as large fixed costs and fluctuations in supply and demand.
Like industries from aviation to financial services, the cement business has been on a "big is beautiful" march over the past five decades. A rush of expansions, mergers, acquisitions, and consolidations has reshaped the industry. The model has not necessarily created value for companies or their investors.
