I hate to post a short idea on a day when the stock is down almost 10%; it's a bad time to sell or short something down a lot on short term news (earnings announcement).
But this is something I haven't looked at in a while so I decided to take a look (I actually started to look at this before the earnings announcement), and my opinion actually has very little to do with the results announced yesterday.
Anyway, what prompted me to look at this is that it is trading at what looks like 100x p/e ratio, which is very high. Of course, shorting high p/e stocks in general is not always a winning strategy so this is not something I would typically look at.
But in this case, it looks a little interesting to dig a little. I think part of the exuberance here is the halo effect from the iPad and Apple's success; the market may be reading that Amazon can grab some of the share and profits from Apple with the Kindle Fire.
This may be true. Maybe Amazon takes some share from Apple and maybe the Kindle is a game changer and iPad killer (Even though the Kindle may be great, I don't think it's in the same market as the iPad, actually).
Before I go on, I should say that I am a huge fan of Amazon. I have watched them grow over the years and really think Jeff Bezos is doing an amazing thing. He reminds me of Costco's Sinegal, where he really wants to treat the customers right and go for the long term loyalty of customers over short term profits. Bezos, like Sinegal, seems to be looking really long term.
One of my favorite things is the customer reviews where Amazon doesn't edit bad reviews. Of course, this upset suppliers early on but Bezos took the side of the customer and allowed it. This may have seemed short term bad, but it turned out to be a long term good as it enhanced the trust of Amazon. (I once tried to post a highly negative review of a Dell product on the Dell website, but the review never was posted! Not so unpredictably, reviews were mostly 5 stars. I tried to post my 1 star review many, many times and it never got posted).
In a recent Wired magazine interview, Bezos also said that he would rather have low margins and a lot of customers rather than vice-versa. Again, this is like an online version of Costco.
OK, so let's first look at the p/e ratio. Amazon just announced the 2011 full year EPS and it came in at $1.37. The stock is trading at $176/share as I type, so that's 128x p/e ratio. But wait, maybe earnings were hit this year due to forward looking investments. So let's look at the peak EPS in 2010 of $2.53. Against that, the stock is trading at 70x p/e.
For the current year ending December 2012, analysts estimate an EPS of $1.83, so against that, AMZN is now trading at 96x p/e. Not cheap at all. Looking forward, analysts estimate an EPS of $3.38 for the full year ending December 2013 for a forward p/e of 52x. Still pretty expensive, especially given the forward estimate (not a sure thing).
Free Cash Flow per Share
We all know that p/e ratio is not the be-all, end-all of stock valuation. Bezos from early on has insisted that it's not earnings that's important, but free cash flow per share that they will try to optimize over time.
Great. So then let's look at that. Forget about, for a moment, the many reservations I have about AMZN's free cash flow calcuation. First of all, it doesn't take into account stock-based compensation expense, which I actually think is a real expense. Adding it back underestimates cost. Second of all, since AMZN's free cash flow is simply cash flow from operations minus capital investment, it includes changes in working capital. When sales are growing, an increase in accounts payable can significantly increase cash flows (as they receive payments from customers before they pay their suppliers). However, this increase in accounts payable is not sustainable in a steady state situation; it only grows as sales grows. So looking at that and putting a multiple on it is like capitalizing a growth.
A more sustainable, stable free cash flow calculation would be something like net earnings plus depreciation, amortization and some other non-cash expenses less capex.
But anyway, let's give AMZN the benefit of the doubt and look at their free cash flow and free cash flow per share.
Here is a table summarizing some key figures from their 10-k's:
So from this, we can see that in 2009 they hit a peak free cash flow per share figure of $6.61. So AMZN is trading at 27x peak free cash flow per share; not cheap. In the last couple of years, they had free cash per share of around $5.00, so AMZN is trading at 35x free cash flow over the past couple of years. Again, not cheap.
Yes, yes. AMZN is still growing rapidly and these free cash flow figures will grow over time. Maybe they had upfront investment for future growth that will pay off in the future. It is also not clear what the Kindle is costing and how that impacts recent year figures as it is suspected that AMZN is selling them at or below cost to increase market share.
The other figure that AMZN stresses is return on invested capital. AMZN defines that as free cash flow (as defined above) divided by invested capital which is total assets minus current liabilities (excluding current portion of long term debt).
The ROIC figure in the table above shows that figure. This shows that ROIC was pretty good but is trending down from a high of 45% in 2009 to 20% in 2011.
Again, it is not clear why that is and how the Kindle and other new business initiatives may be affecting this over the short term (for presumed returns in the future).
This is how the margins break out:
Also, look at the free cash flow margin. This excludes stock compensation and includes growth in working capital, so again, I am a bit weary of slapping a multiple on that, but again, let's give them the benefit of the doubt.
Since the margins oscillate based, I suppose, on where they are in investing for the future and the payoff, let's look at the average margins over the past few years. I will only look at the profitable years.
Since 2002, the operating margins averaged 4.1% and free cash flow margins averaged 6.6%. OK, so the 2009 11.9% free cash flow margin looks a little suspect; I usually exclude spikey figures like that as aberrations. But let's just leave it there for now.
Valuation of AMZN Based on Average Margins
So sales was up to $48 billion in 2011. Let's assume they achieved average margins. What would've been the EPS? Average operating margin was 4.1%, so operating income would have been around $1.97 billion. Other income in 2011 was $76 million, so add that for a total pretax income of $2.05 billion (I ignore net interest expense which is flattish). Using the 31% tax rate for 2011, that's a net income of $1.41 billion, and with 461 million shares outstanding, that's an EPS of around $3.00/share.
At $176/share, AMZN is still trading at a lofty 60x p/e.
Free cash flow margins averaged 6.6%, so doing the above analysis would give us free cash flow of $3.2 billion, or $6.9/share, giving AMZN a valuation of 25x free cash flow. Not cheap.
So from this, we can conclude that even if we adjust for short term margin effects, AMZN is not cheap. Sales are growing strongly, though, so the question is if and when the margins start to improve.
There have been criticism that AMZN is just buying volume and building unprofitable business. Let's take a look at some of the cost factors.
Why are Margins Declining?
One thing that people mention alot is that AMZN is increasingly depending on sales of electronics and other general merchandise, and less on books and CD's. For example, sales of eletronics and general merchandise (EGM) grew +56% last year versus growth of +19% for the media business, and sales of EGM is now much larger than media (books, CDs etc...).
Let's see how the sales break down:
We can see how much EGM has grown in the past. Almost 70% of the growth in the past five years has come from EGM.
So where is this hurting margins? Do EGM products have lower gross margins? The following table breaks out some of the costs:
But it looks like technology and content cost has been trending up too. So even if some of these things are one time factors, it seems across the board.
The big thing, though, is the claim that AMZN is buying market share and volume with free shipping, Amazon Prime and things like that.
Below is the table of shipping revenues (shipping fees charged to customers) and shipping expense (what AMZN pays to deliver products to customers).
This table is really interesting:
This is big, since operating margins have only averaged 4.1% since 2003. Net shipping costs have increased 2.5% since 2003, so that alone may account for a large part of the decline in operating margins.
So what do we have? We have increasing sales, but with declining margins, increasing net shipping and other costs. Will AMZN be able to keep increasing sales and market share without increasing incentives like subsidized shipping? I don't know. AMZN is betting that customer loyalty due to these incentives will allow them to make back profits later.
Will AMZN be able to increase margins back up without reducing these incentives?
I suspect that with the Kindle, more and more of the fullfillment centers will be dealing with eletronics and other general merchandise instead of books and CDs, which will eventually migrate to the Kindle and other electronic distribution.
At that point, will AMZN still have a moat? (AMZN's moat was it's incredible distribution centers for books/CD's. If this migrates to eletronic distribution, will this reduce their moat?).
Even if AMZN is successful with their online TV and movie distribution, how much value will that add to AMZN? The entire market capitalization of Netflix is less than $7 billion. So even if AMZN succeeded in taking ALL of NFLX's business, that implies an additional $7 billion in value to AMZN. With a current market cap of $80 billion, that adds less than 10% to the value of AMZN.
So as electronics and general merchandise increasingly become a bigger part of AMZN's physical distribution business, can they do it as efficiently as they have done books? I have my doubts about that.
I still like AMZN, the company, and am a big fan of Jeff Bezos but at this valuation in front of what seems to be such major changes in the company going forward, unfortunately, I would have to say I am more comfortable being short this thing rather than long.
