Characteristics of Growth Companies and their Value Drivers


Characteristics of growth companies

            Growth companies are diverse in size, growth prospects and can be spread out over very different businesses but they share some common characteristics that make an impact on how we value them. In this section, we will look at some of these shared features:
  1. Dynamic financials: Much of the information that we use to value companies comes from their financial statements (income statements, balance sheets and statements of cash flows). One feature shared by growth companies is that the numbers in these statements are in a state of flux. Not only can the numbers for the latest year be very different from numbers in the prior year, but can change dramatically even over shorter time periods. For many smaller, high growth firms, for instance, the revenues and earnings from the most recent four quarters can be dramatically different from the revenues and earnings in the most recent fiscal year (which may have ended only a few months ago).
  2. Private and Public Equity: It is accepted as conventional wisdom that the natural path for a young company that succeeds at the earliest stages is to go public and tap capital markets for new funds. There are three reasons why this transition is neither as orderly nor as predictable in practice. The first is that the private to public transition will vary across different economies, depending upon both institutional considerations and the development of capital markets. Historically, growth companies in the United States have entered public markets earlier in the life cycle than growth companies in Europe, partly because this is the preferred exit path for many venture capitalists in the US. The second is that even within any given market, access to capital markets for new companies can vary across time, as markets ebb and flow. In the United States, for instance, initial public offerings increase in buoyant markets and drop in depressed markets; during the market collapse in the last quarter of 2008, initial public offerings came to a standstill. The third is that the pathway to going public varies across sectors, with companies in some sectors like technology and biotechnology getting access to public markets much earlier in the life cycle than firms in other sectors such as manufacturing or retailing. The net effect is that the growth companies that we cover in chapter will draw on a mix of private equity (venture capital) and public equity for their equity capital. Put another way, some growth companies will be private businesses and some will be publicly traded; many of the latter group will still have venture capitalists and founders as large holders of equity.
  3. Size disconnect: The contrast we drew in chapter 1 between accounting and financial balance sheets, with the former focused primarily on existing investments and the latter incorporating growth assets into the mix is stark in growth companies. The market values of these companies, if they are publicly traded, are often much higher than the accounting (or book) values, since the former incorporate the value of growth assets and the latter often do not. In addition, the market values can seem discordant with the operating numbers for the firm – revenues and earnings. Many growth firms that have market values in the hundreds of millions or even in the billions can have small revenues and negative earnings. Again, the reason lies in the fact that the operating numbers reflect the existing investments of the firm and these investments may represent a very small portion of the overall value of the firm.
  4. Use of debt: While the usage of debt can vary across sectors, the growth firms in any business will tend to carry less debt, relative to their value (intrinsic or market), than more stable firms in the same business, simply because they do not have the cash flows from existing assets to support more debt. In some sectors, such as technology, even more mature growth firms with large positive earnings and cash flows are reluctant to borrow money. In other sectors, such as telecommunications, where debt is a preferred financing mode, growth companies will generally have lower debt ratios than mature companies.
  5. Market history is short and shifting: We are dependent upon market price inputs for several key components of valuation and especially so for estimating risk parameters (such as betas). Even if growth companies are publicly traded, they tend to have short and shifting histories. For example, an analyst looking at Google in early 2009 would have been able to draw on about 4 years of market history (a short period) but even those 4 years of data may not be particularly useful or relevant because the company changed dramatically over that period – from revenues in millions to revenues in billions, operating losses to operating profits and from a small market capitalization to a large one. 
While the degree to which these factors affect growth firms can vary across firms, they are prevalent in almost every growth firm.


Growth companies- Value Drivers

Scalable growth

The question of how quickly revenue growth rates will decline at a given company can generally be addressed by looking at the company's specifics – the size of the overall market for its products and services, the strength of the competition and quality of both its products and management.  Companies in larger markets with less aggressive competition (or protection from competition) and better management can maintain high revenue growth rates for longer periods.
            There are a few tools that we can use to assess whether the assumptions we are making about revenue growth rates in the future, for an individual company, are reasonable:
1.     Absolute revenue changes: One simple test is to compute the absolute change in revenues each period, rather than to trust the percentage growth rate. Even experienced analysts often under estimate the compounding effect of growth and how much revenues can balloon out over time with high growth rates. Computing the absolute change in revenues, given a growth rate in revenues, can be a sobering antidote to irrational exuberance when it comes to growth.
2.     Past history: Looking at past revenue growth rates for the firm in question should give us a sense of how growth rates have changed as the company size changed in the past. To those who are mathematically inclined, there are clues in the relationship that can be used for forecasting future growth.
3.     Sector data: The final tool is to look at revenue growth rates of more mature firms in the business, to get a sense of what a reasonable growth rate will be as the firm becomes larger.
In summary, expected revenue growth rates will tend to drop over time for all growth companies but the pace of the drop off will vary across companies.

Sustainable margins

To get from revenues to operating income, we need operating margins over time. The easiest and most convenient scenario is the one where the current margins of the firm being valued are sustainable and can be used as the expected margins over time. In fact, if this is the case, we can dispense with forecasting revenue growth and instead focus on operating income growth, since the two will be the equivalent. In most growth firms, though, it is more likely that the current margin is likely to change over time.
            Let us start with the most likely case first, which is that the current margin is either negative or too low, relative to the sustainable long-term margin. There are three reasons why this can happen. One is that the firm has up-front fixed costs that have to be incurred in the initial phases of growth, with the payoff in terms of revenue and growth in later periods. This is often the case with infrastructure companies such as energy, telecommunications and cable firms. The second is the mingling of expenses incurred to generate growth with operating expenses; we noted earlier that selling expenses at growth firms are often directed towards future growth rather than current sales but are included with other operating expenses. As the firm matures, this problem will get smaller, leading to higher margins and profits. The third is that there might be a lag between expenses being incurred and revenues being generated; if the expenses incurred this year are directed towards much higher revenues in 3 years, earnings and margins will be low today.
            The other possibility, where the current margin is too high and will decrease over time, is less likely but can occur, especially with growth companies that have a niche product in a small market. In fact, the market may be too small to attract the attention of larger, better-capitalized competitors, thus allowing the firms to operate under the radar for the moment, charging high prices to a captive market. As the firm grows, this will change and margins will decrease. In other cases, the high margins may come from owning a patent or other legal protection against competitors, and as this protection lapses, margins will decrease. 
            In both of the latter two scenarios – low margins converging to a higher value or high margins dropping back to more sustainable levels – we have to make judgment calls on what the target margin should be and how the current margin will change over time towards this target. The answer to the first question can be usually be found by looking at both the average operating margin for the industry in which the firm operates and the margins commanded by larger, more stable firms in that industry. The answer to the second will depend upon the reason for the divergence between the current and the target margin. With infrastructure companies, for instance, it will reflect how long it will take for the investment to be operational and capacity to be fully utilized.

Quality Growth

A constant theme in valuation is the insistence that growth is not free and that firms will have to reinvest to grow. To estimate reinvestment for a growth firm, we will follow one of three paths, depending largely upon the characteristics of the firm in question:
1.     For growth firms earlier in the life cycle, we will adopt the same roadmap we used for young growth companies, where we estimated reinvestment based upon the change in revenues and the sales to capital ratio.
Reinvestmentt = Change in revenuest/ (Sales/Capital)
The sales to capital ratio can be estimated using the company's data (and it will be more stable than the net capital expenditure or working capital numbers) and the sector averages. Thus, assuming a sales to capital ratio of 2.5, in conjunction with a revenue increase of $ 250 million will result in reinvestment of $ 100 million.  We can build in lags between the reinvestment and revenue change into the computation, by using revenues in a future period to estimate reinvestment in the current one.
2.     With a growth firm that has a more established track record of earnings and reinvestment, we can use the relationship between fundamentals and growth rates that we laid out in chapter 2:
Expected growth rate in operating income = Return on Capital * Reinvestment Rate + Efficiency growth (as a result of changing return on capital)
In the unusual case where margins and returns and capital have settled into sustainable levels, the second term will drop out of the equation.
3.     Growth firms that have already invested in capacity for future years are in the unusual position of being able to grow with little or no reinvestment for the near term. For these firms, we can forecast capacity usage to determine how long the investment holiday will last and when the firm will have to reinvest again. During the investment holiday, reinvestment can be minimal or even zero, accompanied by healthy growth in revenues and operating income.
With all three classes of firms, though, the leeway that we have in estimating reinvestment needs during the high growth phase should disappear, once the firm has reached its mature phase. The reinvestment in the mature phase should hew strictly to fundamentals:
Reinvestment rate in mature phase = 
In fact, even in cases where reinvestment is estimated independently of the operating income during the growth period, and without recourse to the return on capital, we should keep track of the imputed return on capital (based on our forecasts of operating income and capital invested) to ensure that it stays within reasonable bounds.
