What is stock analysis? Well, there are some that think it has everything to do with the dividend. There are others that only look at charts. There are others that think analyst estimate misses (notice how this is equivalent to companies' earnings beats) are a way to gauge the trajectory of a stock. And yet there are others that are lost in medieval times. We as investors need to move beyond these individual frameworks and start taking a holistic view. Let's take a look at what we mean as it relates to our analysis with Diamond Offshore Drilling (DO).
At Valuentum, we think a comprehensive analysis of a firm's discounted cash-flow valuation and relative valuation versus industry peers is the best way to identify the most attractive stocks at the best time to buy. This process culminates in what we call our Valuentum Buying Index (click here for an in-depth presentation about our methodology), which ranks stocks on a scale from 1 to 10, with 10 being the best. Essentially, we're looking for firms that overlap investment methodologies, thereby revealing the greatest interest by investors (we like firms that fall in the center of the diagram below):
If a company is undervalued both on a DCF and on a relative valuation basis it scores high on our scale. Diamond Offshore Drilling posts a VBI score of 4 on our scale, reflecting our 'fairly valued' DCF assessment of the firm, its attractive relative valuation versus peers, and bearish technicals. We compare Diamond Offshore Drilling to peers Cameron Int'l (CAM), Halliburton (HAL), and Schlumberger (SLB).
• Diamond Offshore earns a ValueCreation™ rating of EXCELLENT, the highest possible mark on our scale. The firm has been generating economic value for shareholders for the past few years, a track record we view very positively. Return on invested capital (excluding goodwill) has averaged 19.8% during the past three years.
• Diamond Offshore is a global offshore oil and gas drilling contractor with a fleet of more than 40 offshore drilling rigs, consisting of about 30 semisubmersibles, 7 jack-ups and 5 drillships.
• Diamond Offshore has an excellent combination of strong free cash flow generation and low financial leverage. We expect the firm's free cash flow margin to average about 15.4% in coming years. Total debt-to- EBITDA was 1.1 last year, while debt-to-book capitalization stood at 24.6%.
• Diamond Offshore has paid over $5 billion of dividends since 2006. On a per share basis, total regular and special dividends have amounted to $36.76. We like its shareholder focus and negligible debt load. The firm is the only A-credit-rated drilling contractor.
• Though we point to Core Labs as our favorite oilfield service company from a fundamental standpoint, Diamond's ROCE (return on capital employed) performance is the best among drillers: ATW, ESV, SDRL, NE, RIG, RDC.
Economic Profit Analysis
The best measure of a firm's ability to create value for shareholders is expressed by comparing its return on invested capital - ROIC - with its weighted average cost of capital - WACC. The gap or difference between ROIC and WACC is called the firm's economic profit spread. Diamond Offshore's 3-year historical return on invested capital (without goodwill) is 19.8%, which is above the estimate of its cost of capital of 9.9%. As such, we assign the firm a ValueCreation™ rating of EXCELLENT. In the chart below, we show the probable path of ROIC in the years ahead based on the estimated volatility of key drivers behind the measure. The solid grey line reflects the most likely outcome, in our opinion, and represents the scenario that results in our fair value estimate.
Cash Flow Analysis
Firms that generate a free cash flow margin (free cash flow divided by total revenue) above 5% are usually considered cash cows. Diamond Offshore's free cash flow margin has averaged about 21.8% during the past 3 years. As such, we think the firm's cash flow generation is relatively STRONG. The free cash flow measure shown above is derived by taking cash flow from operations less capital expenditures and differs from enterprise free cash flow (FCFF), which we use in deriving our fair value estimate for the company. For more information on the differences between these two measures, please visit our website at Valuentum.com. At Diamond Offshore, cash flow from operations increased about 2% from levels registered two years ago, while capital expenditures expanded about 62% over the same time period.
The estimated fair value of $79 per share represents a price-to-earnings (P/E) ratio of about 15.2 times last year's earnings and an implied EV/EBITDA multiple of about 8.2 times last year's EBITDA. Our model reflects a compound annual revenue growth rate of 8% during the next five years, a pace that is higher than the firm's 3-year historical compound annual growth rate of - 6.3%. Our model reflects a 5-year projected average operating margin of 29.9%, which is below Diamond Offshore's trailing 3-year average. Beyond year 5, we assume free cash flow will grow at an annual rate of 3% for the next 15 years and 3% in perpetuity. For Diamond Offshore, we use a 9.9% weighted average cost of capital to discount future free cash flows.
Margin of Safety Analysis
Our discounted cash flow process values each firm on the basis of the present value of all future free cash flows. Although we estimate the firm's fair value at about $79 per share, every company has a range of probable fair values that's created by the uncertainty of key valuation drivers (like future revenue or earnings, for example). After all, if the future was known with certainty, we wouldn't see much volatility in the markets as stocks would trade precisely at their known fair values. Our ValueRisk™ rating sets the margin of safety or the fair value range we assign to each stock. In the graph below, we show this probable range of fair values for Diamond Offshore. We think the firm is attractive below $59 per share (the green line), but quite expensive above $99 per share (the red line). The prices that fall along the yellow line, which includes our fair value estimate, represent a reasonable valuation for the firm, in our opinion.
Future Path of Fair Value
We estimate Diamond Offshore's fair value at this point in time to be about $79 per share. As time passes, however, companies generate cash flow and pay out cash to shareholders in the form of dividends. The chart below compares the firm's current share price with the path of Diamond Offshore's expected equity value per share over the next three years, assuming our long-term projections prove accurate. The range between the resulting downside fair value and upside fair value in Year 3 represents our best estimate of the value of the firm's shares three years hence. This range of potential outcomes is also subject to change over time, should our views on the firm's future cash flow potential change. The expected fair value of $105 per share in Year 3 represents our existing fair value per share of $79 increased at an annual rate of the firm's cost of equity less its dividend yield. The upside and downside ranges are derived in the same way, but from the upper and lower bounds of our fair value estimate range.
