Today we'll do a simple run through of a valuation method used to estimate the attractiveness of Gibson Energy Inc. (TSE:GEI) as an investment opportunity by estimating the company's future cash flows and discounting them to their present value. One way to achieve this is by employing the Discounted Cash Flow (DCF) model. There's really not all that much to it, even though it might appear quite complex.
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.

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.
A DCF is all about the idea that a dollar in the future is less valuable than a dollar today, so we discount the value of these future cash flows to their estimated value in today's dollars:
2025 | 2026 | 2027 | 2028 | 2029 | 2030 | 2031 | 2032 | 2033 | 2034 | |
Levered FCF (CA$, Millions) | CA$315.0m | CA$442.0m | CA$447.5m | CA$452.6m | CA$456.0m | CA$461.3m | CA$468.4m | CA$476.8m | CA$486.1m | CA$496.2m |
Growth Rate Estimate Source | Analyst x4 | Analyst x4 | Analyst x4 | Analyst x2 | Analyst x2 | Est @ 1.18% | Est @ 1.54% | Est @ 1.78% | Est @ 1.96% | Est @ 2.08% |
Present Value (CA$, Millions) Discounted @ 8.3% | CA$291 | CA$377 | CA$352 | CA$329 | CA$306 | CA$285 | CA$268 | CA$251 | CA$237 | CA$223 |
("Est" = FCF growth rate estimated by Simply Wall St)
Present Value of 10-year Cash Flow (PVCF) = CA$2.9b
The second stage is also known as Terminal Value, this is the business's cash flow after 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 (2.4%) 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 8.3%.
Terminal Value (TV)= FCF2034 × (1 + g) ÷ (r – g) = CA$496m× (1 + 2.4%) ÷ (8.3%– 2.4%) = CA$8.5b
Present Value of Terminal Value (PVTV)= TV / (1 + r)10= CA$8.5b÷ ( 1 + 8.3%)10= CA$3.8b
The total value is the sum of cash flows for the next ten years plus the discounted terminal value, which results in the Total Equity Value, which in this case is CA$6.7b. In the final step we divide the equity value by the number of shares outstanding. Relative to the current share price of CA$21.9, the company appears quite undervalued at a 47% discount to where the stock price trades currently. 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.
Now 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 Gibson Energy 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 8.3%, which is based on a levered beta of 1.379. 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.
Whilst important, the DCF calculation ideally won't be the sole piece of analysis you scrutinize for a company. DCF models are not the be-all and end-all of investment valuation. 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. 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. Can we work out why the company is trading at a discount to intrinsic value? For Gibson Energy, we've compiled three additional aspects you should further examine:
