Reasons why a company may choose external growth over internal
growth:
Economies of scale, tax considerations & more rapid
growth.
- Economies of scale: economies of scale are nothing but cost
advantages enjoyed by a company as a result of company’s production
becoming efficient. The example can be Nissan that merged with
Mitsubishi. The merger happened as Nissan can reduce potential
duplication cost by setting up dealership across the area.
Mitsubishi has a strong presence in Thailand where Nissan has weak
market presence.
- Tax considerations: i couldn’t find any example for this.
- Rapid growth: Big oil got even bigger in 1999, when Exxon and
Mobil signed an $81 billion agreement to merge and form ExxonMobil.
Not only did Exxon Mobil become the largest company in the world,
it reunited its 19th Century former selves — John D. Rockefeller’s
Standard Oil Company of New Jersey (Exxon) and Standard Oil Company
of New York (Mobil). The merger was so big, in fact, that the FTC
required a massive restructuring of many of Exxon and Mobil’s gas
stations, in order to avoid outright monopolization (despite the
FTC’s 4-0 approval of the merger).
