Apple's Crown Jewel: Valuing the iPhone Franchise

As with my last two posts, I want to set the record straight on my posts on Apple in the last couple of years. In January 2011, I posted on Apple's immense cash balance (of $50-$60 billion at the time). and argued that, as a long-term investor in the company, it has earned my trust after an unmatched decade of success, both in terms of profitability and stock returns, and that I was okay with them holding on to the cash. In March 2012, I returned to the question partly in response to news stories that suggested that Apple may initiate a dividend. Noting that dividends would attract a very different group of stockholders into the company and put them on collision course with the existing stockholder base, I posted that if Apple was intent on returning the cash (as Tim Cook seemed to be), it should do a large stock buyback. I also valued the company at about $710/share (the stock price was about $550 at the time). In April 2012, the stock hit $600 and I bid my farewell to the company as an investment, with much regret and gratitude. I justified my decision to sell not on valuation (since I found the stock to be worth $700+) but on two counts. First, I argued that the company had become a momentum play and that the pricing process had lost its connection to the valuation process. Second, I also felt uncomfortable with the mix of dividend, growth and momentum stockholders, with differing expectations about the company and differing demands of it. Even though Apple’s stock price has gone up about 10% since I sold it, I have no regrets about selling. Since my original case for selling the shares was predicated on a fickle investor base with conflicting views, I believe that the stock price gyrations over the last six months supports that thesis. The stock price dropped as low as $530 and now risen to its high for the year without any dramatic news announcements for the most part driving the price (until the last week). My intrinsic valuation has not changed much in that period and remains over $700, with the updated numbers through the end of last quarter. 

No matter what your views (bullish or bearish) are on Apple, I think that there can be little disagreement on the proposition that Apple's market value rides more on one product, the iPhone than ever before and that it is worth taking a closer look at the underpinnings of that value. Looking at the numbers, here are three key points worth making about the iPhone franchise (and its value to Apple):

1. The iPhone is a money machine: In the most recent twelve months, the iPhone generated about $100 billion in revenues and approximately $21 billion in after-tax profits for Apple.
2. The iPhone is a dominant player in a growing market: The smartphone market grew about 40% last year,  primarily as cell phone users switch to smart phones. During the year,  more than 150 million smart phones were sold, with Apple accounting for about 20% of the units sold. However, with its heftier price tag on the iPhones, Apple had a 43% share of the market, if it is defined in dollar revenues. 
3. The iPhone has a short life cycle: One of the reasons for Apple's disappointing earnings in the most recent quarter is that customers stopped buying the iPhone 4S, waiting for the iPhone 5 to arrive. Since the iPhone 4 came out in June 2010 and the iPhone 4S was introduced in October 2011, that puts about a two-year life cycle on the product.  So what? Companies like P&G or Coca Cola produce products that have very long life cycles; diapers and sodas have not only not changed much over the last few decades but are unlikely to change by much over the next few. Protected by strong brand names, they can be expected to generate earnings for long periods, with relatively little investment or innovation by the companies in question. With a short product life cycle, a company is faced with two challenges. First, it has to come up with innovations to its product to retain its customers when the cycle is renewed, and that will require investment, especially during the later parts of each cycle. Second, even with these innovations, there will be customers who switch to competitors' products (either because they are cheaper or because their innovations are more attractive) and for a company to maintain it's market share, it has to get more of it's competitors' customers to switch to its products. 

Given the iPhone's profitability and dominance in the growing smartphone market, I tried to value the iPhone franchise, incorporating the effect of the short life cycle. In assessing the value, I made the following assumptions.

1. Profitability: Apple will be able to maintain its current after-tax operating margin of 21% on future iPhone sales. 
2. Smartphone market: The smart phone market will continue to grow at a 6% compounded rate for the next 10 years, with growth tapering down towards the growth rate of the economy in the long term. 
3. Product life cycle: The life cycle for a new iPhone will continue to be two years and Apple will have to reinvest half its after-tax operating income in the second year of each cycle (this 50% also incorporate the lost sales in the second year, as each iPhone ages and customers wait for the next version).
4. Switching assumptions: iPhone customers are assumed to be loyal, with only 5% switching to competitors' products at the end of each life cycle. Apple will be more successful at attracting competitors' customers, with 10% switching into iPhones. 
5. Risk: Needless to say, there is substantial risk in this process and the cost of capital of 11% (at the 90th percentile for US companies) reflects that risk.

The value that I estimate for the iPhone franchise is $307 billion, working out to a multiple of 3.39 times revenues and about 16.17 times net income on the iPhone. You can download the spreadsheet that I used and change the assumptions, if you so desire. In fact, as with my Groupon and Facebook valuations, I have opened a shared Google spreadsheet for you to enter your estimates of value for the iPhone franchise.

Here is the larger point, though. About 55% of Apple's business value comes from its iPhone franchise and there are three pressure points that will test this value.

• The first is Apple's capacity to maintain pricing power and earn its current margins; there isn't a competitor within shouting distance of Apple, when it comes to margins. If the after-tax margin drops to 15% from its current 21%, the value of the franchise drops to $219 billion.
• The second is that Apple will be able to prevent the life cycle from speeding up further and that it can continue to innovate at a reasonable cost (with this cost in conjunction with the loss in earnings during the second part of the cycle not exceeding 50% of the after-tax earnings during the period). Reducing the life cycle to one year from two almost halves the value of the franchise.
• The third is that Apple is able to maintain a net positive switching ratio (more of the competitors' customers switch to Apple than vice versa), allowing it to increase in market share in dollar value terms. Assuming a neutral switching ratio (customers switching in = customers switching out), reduces the value of the franchise to $255 billion. 

There is an internal tension between these three variables, since keeping iPhone prices high (preserving the high margins) and spending less on innovation (reducing the cost of innovation) may increase the risk that more customers will switch away than into the iPhone. Using the "life cycle" model also provides some perspective on why the lawsuit victory against Samsung may have a bigger effect on the value of the iPhone franchise than how the iPhone 5 fares with customers in a few weeks. Samsung's loss will have a deterrent effect on competitors planning an assault on the iPhone kingdom, thus increasing Apple's pricing power (preserving margins) and improving its odds of holding on to its customers (improving its switching ratio).

With the iPod, iPhone and iPad, the company has been able to count on the unmatched loyalty of its customers, while both attracting customers of less innovative competitors and increasing overall market size. The question that investors face right now is whether Apple can continue its winning streak. The high valuations attached to the company assume that the company can keep doing what it is right now, that the iPhone 5 will not only launch successfully, but be followed by the iPad Mini and the iPhone 6 and so on. The risk that investors have to take into account when investing in Apple is that somewhere along the way, the winning streak may will be broken. Unlike other large market cap companies with long product life cycles or diversified product portfolios, Apple’s value rests on being a Phoenix, constantly reinventing itself every few years.
