Synergy is the value created after combining two individual entities, which is not possible while operating individually. Two firms can merge to form one company that is capable of being more productive, cost effective and is able to eliminate redundant processes than two individual firms working independently. Basically a firm usually create synergies in two forms i.e. operating and financial.
Operating synergies is an efficiency gain attained through vertical and horizontal merger. It basically includes both economies of scale and economies of scope. While the financial synergies help in enhancing the financial metrics of the company in need by having a better access to capital via merger. As companies always welcome synergies, but there are no free lunches and these benefits do not come without a cost to them.
Before getting into any deal transaction, cost and pricing analysis is most critical in the whole process. In simple terms, synergy is the difference in net worth of both firms before and post merger or we can simply state:
a) Assumptions taken for making forecasts should be critically reviewed.
b) Probability of different scenarios like optimistic, pessimistic and realistic should be done through Monte Carlo simulation.
c) Timing of deal should be taken into consideration while evaluating the prospect of the deal.
It is not a hidden fact that two third of the merger deals fail to deliver their own terms. At the same time we cannot become skeptical about the successful deals because we have great examples like Vodafone- Mannesman, Exxon- Mobile Corp, Glaxo-SmithKline and AOL- Time Warner acquisition etc. However, to make any deal successful, an analyst should make realistic estimates taking into account all costs and issues associated with combined entity encompassing strategic vision, system integration and operating strategy.
