Does the June share price for Keane Group, Inc. (NYSE:FRAC) reflect what it's really worth? Today, we will estimate the stock's intrinsic value by projecting its future cash flows and then discounting them to today's value. I will use the Discounted Cash Flow (DCF) model. Don't get put off by the jargon, the math behind it is actually quite straightforward.

Companies can be valued in a lot of ways, so we would point out that a DCF is not perfect for every situation. If you want to learn more about discounted cash flow, the rationale behind this calculation can be read in detail in the Simply Wall St analysis model.

### The calculation

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. To start off with, we need to estimate 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 need to discount the sum of these future cash flows to arrive at a present value estimate:

#### 10-year free cash flow (FCF) estimate

2019 | 2020 | 2021 | 2022 | 2023 | 2024 | 2025 | 2026 | 2027 | 2028 | |

Levered FCF ($, Millions) | $119.66 | $150.61 | $123.00 | $106.62 | $97.55 | $92.54 | $89.97 | $88.96 | $88.99 | $89.74 |

Growth Rate Estimate Source | Analyst x8 | Analyst x7 | Analyst x1 | Est @ -13.32% | Est @ -8.5% | Est @ -5.13% | Est @ -2.78% | Est @ -1.12% | Est @ 0.03% | Est @ 0.84% |

Present Value ($, Millions) Discounted @ 10.35% | $108.44 | $123.70 | $91.55 | $71.91 | $59.63 | $51.26 | $45.17 | $40.47 | $36.69 | $33.53 |

**Present Value of 10-year Cash Flow (PVCF)**= $662.35m

"Est" = FCF growth rate estimated by Simply Wall St

After calculating the present value of future cash flows in the intial 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 10-year government bond rate of 2.7%. We discount the terminal cash flows to today's value at a cost of equity of 10.3%.

**Terminal Value (TV)** = FCF_{2029} Ã— (1 + g) Ã· (r â€“ g) = US$90m Ã— (1 + 2.7%) Ã· (10.3% â€“ 2.7%) = US$1.2b

**Present Value of Terminal Value (PVTV)** = TV / (1 + r)^{10} = $US$1.2b Ã· ( 1 + 10.3%)^{10} = $452.31m

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 $1.11b. In the final step we divide the equity value by the number of shares outstanding. **This results in an intrinsic value estimate of $10.63**. Relative to the current share price of $7.03, the company appears quite undervalued at a 34% 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.

### The assumptions

The calculation above is very dependent on two assumptions. The first is the discount rate and the other is the 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 Keane Group 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 10.3%, which is based on a levered beta of 1.278. 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.

### Next Steps:

Whilst important, DCF calculation shouldnâ€™t be the only metric you look at when researching a company. The DCF model is not a perfect stock valuation tool. Rather it should be seen as a guide to "what assumptions need to be true for this stock to be under/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. What is the reason for the share price to differ from the intrinsic value? For Keane Group, I've compiled three essential factors you should further examine:
