Today we'll do a simple run through of a valuation method used to estimate the attractiveness of Saia, Inc. (NASDAQ:SAIA) as an investment opportunity by projecting its future cash flows and then discounting them to today's value. We will take advantage of the Discounted Cash Flow (DCF) model for this purpose. Before you think you won't be able to understand it, just read on! It's actually much less complex than you'd imagine.
Companies can be valued in a lot of ways, so we would point out that a DCF is not perfect for every situation. Anyone interested in learning a bit more about intrinsic value should have a read of the Simply Wall St analysis model.
What's the estimated valuation?
We're using the 2-stage growth model, which simply means we take in account two stages of company's growth. In the initial period the company may have a higher growth rate and the second stage is usually assumed to have a stable growth rate. In the first stage we need to estimate the cash flows to the business over the next ten years. 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 need to discount the sum of these future cash flows to arrive at a present value estimate:
10-year free cash flow (FCF) forecast
|Levered FCF ($, Millions)||US$173.7m||US$232.0m||US$287.8m||US$338.0m||US$381.3m||US$417.7m||US$448.0m||US$473.4m||US$495.0m||US$513.8m|
|Growth Rate Estimate Source||Analyst x2||Est @ 33.54%||Est @ 24.07%||Est @ 17.44%||Est @ 12.79%||Est @ 9.54%||Est @ 7.27%||Est @ 5.68%||Est @ 4.56%||Est @ 3.78%|
|Present Value ($, Millions) Discounted @ 6.4%||US$163||US$205||US$239||US$264||US$280||US$288||US$291||US$289||US$284||US$277|

Present Value of 10-year Cash Flow (PVCF) = US$2.6b
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. The Gordon Growth formula is used to calculate Terminal Value at a future annual growth rate equal to the 5-year average of the 10-year government bond yield of 2.0%. We discount the terminal cash flows to today's value at a cost of equity of 6.4%.
Terminal Value (TV)= FCF2031 × (1 + g) ÷ (r – g) = US$514m× (1 + 2.0%) ÷ (6.4%– 2.0%) = US$12b
Present Value of Terminal Value (PVTV)= TV / (1 + r)10= US$12b÷ ( 1 + 6.4%)10= US$6.4b
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$9.0b. In the final step we divide the equity value by the number of shares outstanding. Compared to the current share price of US$354, the company appears around fair value at the time of writing. Valuations are imprecise instruments though, rather like a telescope - move a few degrees and end up in a different galaxy. Do keep this in mind.
We would point out that the most important inputs to a discounted cash flow are the discount rate and of course the actual cash flows. You don't have to agree with these inputs, I recommend redoing the calculations yourself and playing with them. 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 Saia 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 6.4%, which is based on a levered beta of 1.009. 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.
Valuation is only one side of the coin in terms of building your investment thesis, and it shouldn't be the only metric you look at when researching a company. DCF models are not the be-all and end-all of investment valuation. Preferably you'd apply different cases and assumptions and see how they would impact the company's valuation. If a company grows at a different rate, or if its cost of equity or risk free rate changes sharply, the output can look very different. For Saia, we've compiled three important aspects you should consider:
- Risks: Consider for instance, the ever-present spectre of investment risk. We've identified 2 warning signs with Saia , and understanding these should be part of your investment process.
