One of the reasons our members love us is that we tell the story through the numbers. Every income statement says something, every balance sheet has a history and every cash flow statement reveals a firm's true intrinsic value. The numbers talk--and we think every investor should listen to them. Let's see what they say about Airgas (ARG).

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.

If a company is undervalued both on a DCF and on a relative valuation basis it scores high on our scale. Airgas posts a VBI score of 6 on our scale, reflecting our 'fairly valued' DCF assessment of the firm and its unattractive relative valuation versus peers. We compare Airgas to peers Dow Chemical (DOW), Praxair (PX), and DuPont (DD). In the spirit of transparency, we show how the performance of our VBI has stacked up per underlying score:

Investment Considerations

Investment Highlights

• Airgas scores fairly well on our business quality matrix. The firm has put up solid economic returns for shareholders during the past few years with relatively low volatility in its operating results. Return on invested capital (excluding goodwill) has averaged 12.4% during the past three years.

• Airgas is a leader in the US packaged gas market, boasting roughly 25% share. It has strong positions in US packaged industrial, medical, and specialty gases and is a top producer of atmospheric gases.

• Airgas' cash flow generation and financial leverage are at decent levels, in our opinion. The firm's free cash flow margin and debt-to-EBITDA metrics are about what we'd expect from an average firm in our coverage universe.

• The firm experienced a net income CAGR of about 6.3% during the past 3 years. We expect its net income growth to be better than its peer median during the next five years.

Business Quality

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. Airgas' 3-year historical return on invested capital (without goodwill) is 12.4%, which is above the estimate of its cost of capital of 9.5%. As such, we assign the firm a ValueCreation™ rating of GOOD. 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. Airgas' free cash flow margin has averaged about 4.8% during the past 3 years. As such, we think the firm's cash flow generation is relatively MEDIUM. 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 Airgas, cash flow from operations decreased about 15% from levels registered two years ago, while capital expenditures expanded about 41% over the same time period.

Valuation Analysis

The estimated fair value of $96 per share represents a price-to-earnings (P/E) ratio of about 24 times last year's earnings and an implied EV/EBITDA multiple of about 11.1 times last year's EBITDA. Our model reflects a compound annual revenue growth rate of 4.3% during the next five years, a pace that is higher than the firm's 3-year historical compound annual growth rate of 3%. Our model reflects a 5-year projected average operating margin of 15.4%, which is above Airgas' trailing 3-year average. Beyond year 5, we assume free cash flow will grow at an annual rate of 3.1% for the next 15 years and 3% in perpetuity. For Airgas, we use a 9.5% 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 $96 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 Airgas. We think the firm is attractive below $77 per share (the green line), but quite expensive above $115 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 Airgas' fair value at this point in time to be about $96 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 Airgas' 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 $125 per share in Year 3 represents our existing fair value per share of $96 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.
