172  Growth We also analyzed the decay rates for the most recent 15 years and found similar patterns of rapid convergence to 5 percent and lower (Exhibit 9.11). Note how the 2008 credit crisis caused a temporary decline of growth rates overall but without changing the typical decay pattern from the long-term data in Exhibit 9.10. Comparing the decay of growth to that of ROIC shown in the previous chapter, it is possible to see that although companies’ rates of return on invested capital generally remain fairly stable over time—top com- panies still outperform bottom companies by more than ten percentage points after 15 years—rates of growth do not. As discussed earlier in this chapter, companies struggle to maintain high growth because product life cycles are finite and growing becomes more diffi- cult as companies get bigger. Do any companies counter this norm? The short answer: very few. Exhibit 9.12 shows what happened to the growth rates of companies grouped by their 2004–2007 growth rates. Reading across each row, the percentages indicate the share of companies in each group that fell into each of the growth categories one decade later. Clearly, maintaining high growth is much less common than being stuck with slow growth. Of the com- panies reporting less than 5 percent revenue growth from 2004 to 2007, 68 percent continued to report growth below 5 percent ten years later. In contrast, only 21 percent of high-growth companies maintained better than 15 percent real growth ten years later. Even more concerning for high-growth compa- nies, 58 percent of the companies that grew faster than 15 percent from 2004 to 2007 were growing at real rates below 5 percent a decade later. Sustaining high growth is very difficult—much more difficult than sustaining high ROIC.

For large companies, the growth of the markets in which they operate largely drives long-term revenue growth. Although gains in market share contribute to revenues in the short term, these gains are far less important for long-term growth. Revenue growth is not all that matters for creating value; the value created per dollar of additional revenues is the crucial point. In general, this depends on how easily competitors can respond to a company’s growth strategy. The growth strategy with the highest potential in this respect is true product in- novation, because entirely new product categories by definition have no es- tablished competition. Attracting new customers to an existing product or persuading existing customers to buy more of it also can create substantial value, because direct competitors in the same market tend to benefit as well. Growth through bolt-on acquisitions can add value, because such acquisitions can boost revenue growth at little additional cost and complexity. Typically, revenue growth from market share gains is much less attractive, because it comes at the expense of established direct competitors, who are likely to retali- ate, especially in maturing markets. Sustaining high growth is no less a challenge than initiating it. Because most products have natural life cycles, the only way to achieve lasting high growth is to continue introducing new products at an increasing rate—which is nearly impossible. Not surprisingly, growth rates for large companies decay much faster than do returns on invested capital; growth rates for even the fastest-growing companies tend to fall below 5 percent within ten years.
