Sleep Number Corporation (NASDAQ:SNBR) Shares Could Be 49% Below Their Intrinsic Value Estimate

Does the January share price for Sleep Number Corporation (NASDAQ:SNBR) reflect what it's really worth? Today, we will estimate the stock's intrinsic value by taking the expected future cash flows and discounting them to today's value. The Discounted Cash Flow (DCF) model is the tool we will apply to do this. Models like these may appear beyond the comprehension of a lay person, but they're fairly easy to follow.

We would caution that there are many ways of valuing a company and, like the DCF, each technique has advantages and disadvantages in certain scenarios. For those who are keen learners of equity analysis, the Simply Wall St analysis model here may be something of interest to you.

The Method

We use what is known as a 2-stage model, which simply means we have two different periods of growth rates for the company's cash flows. Generally the first stage is higher growth, and the second stage is a lower growth phase. To begin with, we have to get estimates of the next ten years of cash flows. Where possible we use analyst estimates, but when these aren't available we extrapolate the previous free cash flow (FCF) from the last estimate or reported value. We assume companies with shrinking free cash flow will slow their rate of shrinkage, and that companies with growing free cash flow will see their growth rate slow, over this period. We do this to reflect that growth tends to slow more in the early years than it does in later years.

Generally we assume that a dollar today is more valuable than a dollar in the future, so we discount the value of these future cash flows to their estimated value in today's dollars:

10-year free cash flow (FCF) estimate

	2023	2024	2025	2026	2027	2028	2029	2030	2031	2032
Levered FCF ($, Millions)	US$16.1m	US$62.9m	US$84.6m	US$109.8m	US$128.8m	US$145.2m	US$158.9m	US$170.4m	US$180.1m	US$188.3m
Growth Rate Estimate Source	Analyst x1	Analyst x1	Analyst x1	Analyst x1	Est @ 17.30%	Est @ 12.70%	Est @ 9.49%	Est @ 7.23%	Est @ 5.66%	Est @ 4.55%
Present Value ($, Millions) Discounted @ 12%	US$14.4	US$50.4	US$60.7	US$70.6	US$74.1	US$74.8	US$73.3	US$70.4	US$66.6	US$62.4

("Est" = FCF growth rate estimated by Simply Wall St)
Present Value of 10-year Cash Flow (PVCF) = US$618m

After calculating the present value of future cash flows in the initial 10-year period, we need to calculate the Terminal Value, which accounts for all future cash flows beyond the first stage. For a number of reasons a very conservative growth rate is used that cannot exceed that of a country's GDP growth. In this case we have used the 5-year average of the 10-year government bond yield (2.0%) to estimate future growth. In the same way as with the 10-year 'growth' period, we discount future cash flows to today's value, using a cost of equity of 12%.

Terminal Value (TV)= FCF₂₀₃₂ × (1 + g) ÷ (r – g) = US$188m× (1 + 2.0%) ÷ (12%– 2.0%) = US$2.0b

Present Value of Terminal Value (PVTV)= TV / (1 + r)¹⁰= US$2.0b÷ ( 1 + 12%)¹⁰= US$655m

The total value, or equity value, is then the sum of the present value of the future cash flows, which in this case is US$1.3b. In the final step we divide the equity value by the number of shares outstanding. Relative to the current share price of US$29.5, the company appears quite undervalued at a 49% discount to where the stock price trades currently. The assumptions in any calculation have a big impact on the valuation, so it is better to view this as a rough estimate, not precise down to the last cent.

Important Assumptions

The calculation above is very dependent on two assumptions. The first is the discount rate and the other is the cash flows. Part of investing is coming up with your own evaluation of a company's future performance, so try the calculation yourself and check your own assumptions. The DCF also does not consider the possible cyclicality of an industry, or a company's future capital requirements, so it does not give a full picture of a company's potential performance. Given that we are looking at Sleep Number as potential shareholders, the cost of equity is used as the discount rate, rather than the cost of capital (or weighted average cost of capital, WACC) which accounts for debt. In this calculation we've used 12%, which is based on a levered beta of 1.615. Beta is a measure of a stock's volatility, compared to the market as a whole. We get our beta from the industry average beta of globally comparable companies, with an imposed limit between 0.8 and 2.0, which is a reasonable range for a stable business.

SWOT Analysis for Sleep Number

Strength

• Debt is well covered by earnings and cashflows.

Opportunity

• Annual earnings are forecast to grow for the next 4 years.

• Trading below our estimate of fair value by more than 20%.

• Significant insider buying over the past 3 months.

Threat

• Total liabilities exceed total assets, which raises the risk of financial distress.

• Annual earnings are forecast to grow slower than the American market.

Moving On:

Although the valuation of a company is important, it ideally won't be the sole piece of analysis you scrutinize for a company. It's not possible to obtain a foolproof valuation with a DCF model. Instead the best use for a DCF model is to test certain assumptions and theories to see if they would lead to the company being undervalued or overvalued. For example, changes in the company's cost of equity or the risk free rate can significantly impact the valuation. Can we work out why the company is trading at a discount to intrinsic value?
