Wall Street has diverse opinions about the company's future. Average fiveyear annualized growth forecast estimate is 9.7%. Given the company's past growth rate of 3.5%, this is a pretty ambitious target.
What is the fair value of Walgreen given the forecast estimates? We can estimate Walgreen's fair value using a discounted earnings plus equity model as follows.
Discounted Earnings Plus Equity Model
This model is primarily used for estimating the returns from longterm projects. It is also frequently used to price fairvalued IPOs. The methodology is based on discounting the present value of the future earnings to the current period:
V = E_{0} + E_{1} /(1+r) + E_{2} /(1+r)^{2} + E_{3}/(1+r)^{3} + E_{4}/(1+r)^{4} + E_{5}/(1+r)^{5} + Disposal Value
V = E_{0} + E_{0} (1+g)/(1+r) + E_{0}(1+g)^{2}/(1+r)^{2} + … + E_{0}(1+g)^{5}/(1+r)^{5} + E_{0}(1+g)^{5}/[r(1+r)^{5}]
The earnings after the last period act as a perpetuity that creates regular earnings:
Disposal Value = D = E_{0}(1+g)^{5}/[r(1+r)^{5}] = E_{5} / r
While this formula might look scary for many of us, it easily calculates the fair value of a stock. All we need is the currentperiod earnings, earnings growth estimate, and the discount rate. To be as objective as possible, I use Morningstar data for my growth estimates. You can set these parameters as you wish, according to your own diligence.
Valuation
Historically, the average return of the DJI has been around 11% (including dividends). Therefore, I will use 11% as my discount rate. In order to smooth the results, I will also take the average of ttm EPS along with the mean EPS estimate for the next year.
E_{0} = EPS = ($2.42 + $3.70) / 2 = $3.06
Wall Street holds diversified opinions on the company's future. While analysts tend to impose subjective opinions on their estimates, the average analyst estimate is a good starting point. Average fiveyear growth forecast is 9.7%. Book value per share is $19.31. The rest is as follows:

I decided to add the book value per share so that we can distinguish between a lowdebt and debtloaded company. The lower boundary does not include the book value. According to my 5year discountedearningsplusbookvalue model, the fairvalue range for Walgreen is between $44 and $62 per share. At a price of $33, Walgreen is trading at a significant discount. The stock has at least 30% upside potential to reach its fair value.
Dividend History
Walgreen has been a nifty dividend payer. The dividends are pretty stable and the company managed to boost dividends by more than 100% in the last 5 years. The recent increase moved the quarterly dividend to 27.5 cents from 22.5 cents. I expect the company to keep increasing its dividends as the payout ratio of 40% leaves substantial room for dividend growth.

Competitors
Other drug retailers seem to be priced with a relatively high premium compared to Walgreen. CVS Caremark (NYSE:CVS) is the largest retailer in the U.S. Even though it offers a substantially lower yield of only 1.4%, it is priced with a forward valuation of 12.4 times the earnings. Another drug retailer Rite Aid (NYSE:RAD) had a quite rollercoaster year. The stock made it to above $2 in the middle of March. However, it kept sliding, and is currently trading 50% below its 52week high.
Summary
Based on the historical valuation metrics, Walgreen is trading at a discount. The trailing P/E ratio of 14 and P/B ratio of 1.8 are significantly lower than the 5year average P/E ratio of 15.2, and P/B ratio of 2.4. The stock looks like a deep bargain as it is trading with low valuation multiples.
Based on my FED+ valuation, Walgreen is substantially undervalued. The stock has at least 30% upside potential to reach its fair valuation range. Analysts also agree with me. In agreement to what my model suggests, their target price of $39 suggests about 28% upside potential. Note that, the traditional retailers are going through tough periods. While drug retailers are more resistant to competition from online outlets, they create a substantial risk for the industry's future.
