Length of Extraordinary Growth Period

The question of how long a firm will be able to sustain high growth is perhaps one of the more difficult questions to answer in a valuation, but two points are worth making. One is that it is not a question of whether but when firms hit the stable growth wall. All firms ultimately become stable growth firms, in the best case, because high growth makes a firm larger and the firm's size will eventually become a barrier to further high growth. In the worst-case scenario, firms may not survive and will be liquidated. The second is that high growth in valuation, or at least high growth that creates value1, comes from firms earning excess returns on their marginal investments. In other words, increased value comes from firms having a return on capital that is well in excess of the cost of capital (or a return on equity that exceeds the cost of equity). Thus, when you assume that a firm will experience high growth for the next 5 or 10 years, you are also implicitly assuming that it will earn excess returns (over and above the required return) during that period. In a competitive market, these excess returns will eventually draw in new competitors and the excess returns will disappear.

We should look at three factors when considering how long a firm will be able to maintain high growth.

1. Size of the firm: Smaller firms are much more likely to earn excess returns and maintain these excess returns than otherwise similar larger firms. This is because

they have more room to grow and a larger potential market. Small firms in large markets should have the potential for high growth (at least in revenues) over long periods. When looking at the size of the firm, you should look not only at its current market share, but also at the potential growth in the total market for its products or services. A firm may have a large market share of its current market, but it may be able to grow in spite of this because the entire market is growing rapidly

2. Existing growth rate and excess returns: Momentum does matter, when it comes to projecting growth. Firms that have been reporting rapidly growing revenues are more likely to see revenues grow rapidly at least in the near future. Firms that are earnings high returns on capital and high excess returns in the current period are likely to sustain these excess returns for the next few years.

3. Magnitude and Sustainability of Competitive Advantages: This is perhaps the most critical determinant of the length of the high growth period. If there are significant barriers to entry and sustainable competitive advantages, firms can maintain high growth for longer periods. If, on the other hand, there are no or minor barriers to entry or if the firm's existing competitive advantages are fading, you should be far more conservative about allowing for long growth periods. The quality of existing management also influences growth. Some top managers2 have the capacity to make the strategic choices that increase competitive advantages and create new ones.

Illustration 4.1: Length of High Growth Period

To illustrate the process of estimating the length of the high growth period, we will consider all of the companies that we will be valuing in the next two chapters and make subjective judgments about how long each one will be able to maintain high
