Tallgrass Energy Partners (NYSE: TEP) Free Cash Flows Reveal Stock’s Upside

in INVESTING IDEAS by

With the stock up 23.6% over the prior month, investors may be tempted to sell their shares of Tallgrass Energy Partners (NYSE: TEP). In this article, I am going to calculate the fair value of Tallgrass Energy by forecasting its future cash flows and discounting them back to today’s value. Value investors may find the results from my analysis surprising.


DCF Methodology

The basic philosophy behind a DCF analysis is that the intrinsic value of a company is equal to the future cash flows of that company, discounted back to present value. The general formula is provided below. The intrinsic value is considered the actual value or “true value” of an asset based on an individual’s underlying expectations and assumptions.

Discounted Cash Flow Formula

Cash flows into the firm in the form of revenue as the company sells its products and services, and cash flows out as it pays its cash operating expenses such as salaries or taxes (taxes are part of the definition for cash operating expenses for purposes of defining free cash flow, even though taxes aren’t generally considered a part of operating income). With the leftover cash, the firm will make short-term net investments in working capital (an example would be inventory and receivables) and longer-term investments in property, plant and equipment. The cash that remains is available to pay out to the firm’s investors: bondholders and common shareholders.

I will take you through my own expectations for Tallgrass Energy as well as explain how I arrived at certain assumptions. The full analysis was completed on Tuesday, April 24. An updated analysis using real-time data can be viewed in your web browser at finbox.io’s Tallgrass Energy DCF analysis page. The steps involved in the valuation are:

1. Forecast Free Cash Flows
  • Create a revenue forecast
  • Forecast EBITDA profit margin
  • Calculate free cash flow
2. Select a discount rate
3. Estimate a terminal value
4. Calculate the equity value

Step 1: Forecast Free Cash Flows

The key assumptions that have the greatest impact on cash flow projections are typically related to growth, profit margin and investments in the business. The analysis starts at the top of the income statement by creating a forecast for revenue and then works its way down to net operating profit after tax (NOPAT), as shown below.

Revenue - Operating Expenses = EBIT - Taxes = NOPAT

NOPAT - Capital Expenditures - NWC Investment + D&A = Unlevered FCF

From NOPAT, deduct cash outflows like capital expenditures and investments in net working capital and add back non-cash expenses from the income statement such as depreciation and amortization to calculate the unlevered free cash flow forecast (shown above).

Create A Revenue Forecast

When available, the finbox.io’s pre-built models use analyst forecasts as the starting assumptions. To forecast revenue, analysts gather data about the company, its customers and the state of the industry. I typically review the analysts’ forecast and modify the growth rates based on historical performance, news and other insights gathered from competitors. Note that if a company only has a small number of analysts giving projections, the consensus forecast tends to not be as reliable as companies that have several analysts’ estimates. Another check for reliability is to analyze the range of estimates. If the range is really wide, it may be less accurate.

Tallgrass Energy Partners owns, develops, and operates midstream energy assets in North America. The company was founded in 2013 and is based in Leawood, Kansas. Analysts covering the stock often compare the company to a peer group that includes Tallgrass Energy GP, LP (NYSE: TEGP), Phillips 66 Partners LP (NYSE: PSXP), Antero Midstream Partners LP(NYSE: AM), and Magellan Midstream Partners L.P. (NYSE: MMP).

Forecast Tallgrass Energy’s EBITDA Profit Margin

The next step is to forecast the company’s earnings before interest, taxes, depreciation and amortization (EBITDA). Note that EBITDA is a commonly used metric in valuation models because it provides a cleaner picture of overall profitability, especially when benchmarking against comparable companies. This is because it ignores non-operating costs that can be affected by certain items such as a company’s financing decisions or political jurisdictions. For more detail, see Tallgrass Energy’s EBITDA definition.

EBITDA margin is calculated by dividing EBITDA by revenue. The higher the EBITDA margin, the smaller the firm’s operating expenses are in relation to its revenue, which may ultimately lead to higher profit. Lower operating expenses for a given level of revenue can be a sign of internal economies of scale.

The charts below compare Tallgrass Energy’s LTM EBITDA margin to the same peer group. The company’s EBITDA margin of 56.7% is above its selected comparable public companies: TEGP (56.5%), PSXP (55.1%) and MMP (49.8%) and below AM (57.9%) and .

Although I don’t specifically walk through my assumptions here, I then forecasted depreciation & amortization, capital expenditures and net working capital based on historical levels.

Calculate Free Cash Flow

With all required forecasts in place, the next step is to calculate projected free cash flow as shown below.

Step 2: Select Tallgrass Energy’s Discount Rate

The next step is to select a discount rate to calculate the present value of the forecasted free cash flows. I used finbox.io’s Weighted Average Cost of Capital (WACC) model to help arrive at an estimate. Generally, a company’s assets are financed by either debt (debt is after tax in the formula) or equity. WACC is the average return expected by these capital providers, each weighted by respective usage. The WACC is the required return on the firm’s assets.

It’s important to note that the WACC is the appropriate discount rate to use because this analysis calculates the free cash flow available to Tallgrass Energy’s bondholders and common shareholders. On the other hand, the cost of equity would be the appropriate discount rate if we were calculating cash flows available only to Tallgrass Energy’s common shareholders (i.e., dividend discount model, equity DCF). This is commonly referred to as the difference between free cash flow to equity (FCFE) and free cash flow to the firm (FCFF). By using the WACC to discount FCFF, we are calculating total firm value. If we discounted FCFE at the required return on equity, we would end up with equity value of the firm. Equity value of the firm is simply total firm value minus the market value of debt.

I determined a reasonable WACC estimate for Tallgrass Energy to be 10.0% at the midpoint. An updated cost of capital analysis using real-time data can be found at finbox.io’s Tallgrass Energy WACC Model Page. The DCF model then does the heavy lifting of calculating the discount factors by applying the mid-year convention technique.


Step 3: Estimate Tallgrass Energy’s Terminal Value

Since it is not reasonable to expect that Tallgrass Energy will cease its operations at the end of the five-year forecast period, we must estimate the company’s continuing value, or terminal value. Terminal value is an important part of the DCF model because it accounts for the largest percentage of the calculated present value of the firm. If you were to exclude the terminal value, you would be excluding all the future cash flow past the horizon period. Using finbox.io, users can choose a five-year or 10-year horizon period to forecast future free cash flow.

The most generally accepted techniques to calculate a terminal value are by applying the Gordon growth approach, using an EBITDA exit multiple and using a revenue exit multiple. This analysis applies the Gordon growth formula:

Terminal Value Calculation Using The Gordon Growth Formula

As the formula suggests, we need to estimate a “perpetuity” growth rate at which we expect Tallgrass Energy’s free cash flows to grow forever. Most analysts suggest that a reasonable rate is typically between the historical inflation rate of 2% to 3% and the historical GDP growth rate of 4% to 5%.

Step 4: Calculate Tallgrass Energy’s Equity Value

The enterprise value previously calculated is a measure of the company’s total value. An equity waterfall is a term often used by valuation firms, referring to the trickle-down process of computing a company’s equity value from its enterprise value. Note that in the event of a bankruptcy, debt holders will be paid in full before anything is distributed to common shareholders. Therefore, we must subtract debt and other financial obligations to determine a firm’s equity value. The general formula for calculating equity value is illustrated in the figure below.

Enterprise Value - Debt - Minority Interest & Other Liabilities - Preferred Equity - Pension + Cash & Equivalents = Total Equity Value

The model uses the formula shown above to calculate equity value and divides the result by the shares outstanding to compute intrinsic value per share as shown at the bottom of the figure below.

Tallgrass Energy's Equity Value Calculation

The assumptions I used in the model imply an intrinsic value per share range of $51.38 to $61.53 for Tallgrass Energy.

Tallgrass Energy’s stock price currently trades at $43.42 as of Tuesday, April 24, 26.1% below the midpoint value of $54.76.


Conclusion: Tallgrass Energy Has Upside Potential

A DCF analysis can seem complex at first, but it’s worth adding to your investment analysis toolbox since it provides the clearest view of company value.

Tallgrass Energy’s stock has made impressive gains over the prior month and investors may very well decide to sell their shares. However, the stock still appears to have further upside potential based on its future cash flow projections.
