'Organic Growth' vs 'Inorganic Growth'

'Organic Growth'
Organic growth is the growth rate a company can achieve by increasing output and enhancing sales internally. This does not include profits or growth acquired from takeovers, acquisitions or mergers. Takeovers, acquisitions and mergers do not bring about profits generated within the company, and are therefore not considered organic growth.


'Inorganic Growth'
Inorganic growth arises from mergers or takeovers rather than an increase in the company's own business activity. Firms that choose to grow inorganically can gain access to new markets through successful mergers and acquisitions. Inorganic growth is seen as a faster way for a company to grow when compared with organic growth.


There are two ways for human beings to keep our heads warm. We can grow hair, or we can put on a hat. It takes a while to grow hair, but we create it ourselves. We do not have to pay money for hair; the body grows hair naturally. The hair is equivalent to organic growth, and a hat is equivalent to inorganic growth. Hair doesn't cost anything, but it takes a while to grow. Those people that don't grow hair fast may be better off buying a hat or a wig if it's cold outside. Likewise, it may be easier for some companies to buy a fast-growing company. Indeed, some companies use acquisitions as the foundation of their growth strategy with the expectation that year-on-year growth is expected to decline. In other words, some companies are losing their hair, and inorganic growth vehicles help to manage the loss.

Not All Growth Is Equal

The best way to explain the importance of differentiating between organic and inorganic growth for investors is with an example.
If company A is growing at a rate of 5% and company B is growing at a rate of 25%, most investors opt for company B. The assumption is company A is growing at a slower rate than company B, and therefore has a lower rate of return. There is another scenario to consider, however. What if company B grew revenues 25% because it bought out its competitor for $12 billion. In fact, the reason company B purchased its competitor is because company B’s sales were declining by 5%.
Company B might be growing, but there appears to be a lot of risk connected to this growth, while company A is growing by 5% without an acquisition or the need to take on more debt. Perhaps company A is the better investment even though it grew at a much slower pace than company B. Some investors may be willing to take on the additional risk, but others opt for the safer investment.


Organic vs. Inorganic Growth

In this example, company A, the safer investment, grew revenue by 5% through organic growth. The growth required no merger or acquisition, and occurred due to an increase in demand for the company’s current products. Company B grew revenue through acquisitions by borrowing money. In fact, organic growth declined by negative 5%. Company B's growth is completely reliant on acquisitions rather than its business model. This is not a good development.

In some industries, particularly in retail, organic growth is referred to as comparable growth or comps, referring to sales based on a comparable base of stores or retail outlets. Inorganic growth is not bad as long as it is being paid for with the company's cash rather than debt or equity financing. A combination of both organic and inorganic growth is ideal as it diversifies the revenue base without relying solely on current operations to grow market share.
