The document discusses the five forces analysis for Crown, Cork and Seal's potential acquisition of Continental Can in 1989. It notes that the metal container industry at the time had strong internal rivalry among the five major competitors. Industry profitability was decreasing due to overcapacity and shrinking customer base. Supplier power was also strong as a small number of aluminum producers supplied the industry. Potential entrants faced significant barriers, but threat of substitution was growing from glass and plastic containers. Overall, the analysis suggests the acquisition could be profitable given the industry conditions.
