AT&T

As you know, as we crossed into 2001, the great crash occurred.

Ben Thompson • 25:05
Yep. And suddenly a job offer from a big phone company sounds pretty great.

Horace Dediu • 25:09
Yeah, but the crash occurred and it impacted my startup because I couldn't raise money anymore. And that's why I'm throwing in the towel. I'll take this idea to Nokia and build it inside of this company. So for the first year, I worked out of the U.S. and then they invited me to come to Finland. And I fell in love with it, not to mention finding someone to fall in love with. Yeah, I'm still here.

So we created an internal venture called media distribution. And it struggled for a couple of years. We partnered with a publishing company here in Finland that is the biggest newspaper and magazine company. And we worked with them. 9-11 happened. We worked with them throughout that period to test this idea of distributing content on phones. That's how I met my wife. She was working for the publishing firm. Remember when Apple News launched? I forget how many years ago it was already. It was five, six years ago. [My wife] texted me during the keynote. She goes, "you realize that's what we were working on together in 2001?"

It was called Project Melissa. Project Melissa was this idea of Apple News today. And that was [our project] 20 years earlier. That just goes to show you the story of my life. I was doing search 10 years before Google existed. I was doing e-books 10 years before Amazon launched the Kindle. I was doing smartphones and media distribution on smartphones 20 years before Apple showed how it's done.

So my problem has been that I see things happening or see where things are going, but way too early. And that's why one of the theses I have over time is the idea that the difference between a futurist and a billionaire is knowing when one thing happens. So it's not about knowing what's going to happen. A lot of people are very good at that.

Ben Thompson • 27:31
Including Nokia, to your point.

Horace Dediu • 27:33
Nokia, science fiction writers, Elon Musk, a lot of people predict this. But getting the timing right is where the money is made. And so that was one of those lessons I learned.

Ben Thompson • 27:45
Well, when you talk about the publishing and Nokia and the reading and all those sorts of things, what it makes me think of is when the iPhone comes along in 2007, And I'm very curious to get your perspective on what that was like inside Nokia when the iPhone launches.

Horace Dediu • 27:59
I'll tell you exactly.

Ben Thompson • 28:00
But before I get there, but to this publishing point specifically, the key bit was the Internet was permissionless in terms of producing content. Like, it's great that you met your wife, but the fact that you needed to be in a situation where you could meet your wife was actually the reason why it wasn't going to happen. Because if you have to make a deal to do everything, it's just never going to get there. Whereas if you can just surf the Internet, the real Internet, and no one needs to do anything to adapt to it, suddenly you get it all for free. And then you get the virtual cycle going where they're making stuff for you. And that was sort of the, that's the timing bit is like the, the external structure around what you're doing.

Horace Dediu • 28:41
Yeah, it's, it's, it's complex and it's multi-causal and you're right. It's multiple, the reasons why things happen the way they are. And it's just not foreseeable. The internet was, and by the way, the thing that really caused the project to fail and be abandoned--this media distribution side note-- it was the fixation on DRM.

DRM actually killed a lot of great businesses with content ideas back in the day, whether it was music or video or textual. It was people just obsessed about protecting it before they obsessed about distributing it and making it great. And this is why when iTunes came along, even though there were some circumstances there with being on a Mac and not on the PC, that the publishers finally said, why don't we go ahead with this?

So long story there. But as far as what Nokia was doing, after four years of doing this startup inside of Nokia that did not work out, I got into the job of strategy analysis and competitive analysis. So they asked me to do Microsoft.

Microsoft was the biggest worry for everyone because they had intentions of being in the phone business. They made no secret about it. They had prototypes. They were working with competitors to Nokia. [Intending to] give them the operating system so that [for instance] Samsung running Microsoft [Mobile]. That was the effort.

They were pushing on all fronts. Nokia was holding out and saying "we've got our own operating system" and so on. So they gave me this job because every other competitor was hardware. All the analysts were covering hardware. I was the only guy who was covering a software company.

And in doing that, I was also sort of nibbling at Apple a little bit because the iPod had come out. The iPod was doing amazing, but it wasn't a phone product. And I was kind of looking at it a little bit.

Now Christensen comes back in the picture, because his book had taken off. He had already written the second book, which is The Innovator Solution. And I was like, hang on a second, a lot of stuff that I read in the book, and I remember back from my days at school, applies to Apple here because they're doing a lot of interesting things with being disruptive as the case may be.

Nokia itself had been disruptive in its early years. But I'm focused on Microsoft. And my point was that we can fight this battle and win, but we got to be very careful. And there's a lot of twists and turns there, but I took it upon myself also to understand what's going to happen with this media product from Apple.

And then I began to write a few internal notes because nobody was covering Apple. This is interesting and important. Imagine you have a team of a dozen analysts, you could put them on multiple jobs, assign people to multiple problems. No one thought that Apple was a problem to be looked at, even part time. No, there was nothing interesting about it.

And part of that had to do with the fact that [Nokia perceived that Apple had been] one foot in the grave already in the 90s. And now they were this little toy media company. They didn't really have scale. Phones were on the orders of billions of users already. And this iPod was in the tens of millions, maybe a hundred million. So it was orders of magnitude. There was no real worry there.

But I was really annoyed at this thing. And I started building a model. I remember distinctly opening a spreadsheet, looking at research reports and thinking to myself, let's look at the history of the iPod, how it's growing. And I started to match that to the Razr, which was the most viral product at the time, the Motorola Razr.

Even Nokia was jealous about this thing. At that time, [Motorola] had cumulative sales of 50 million, which was considered way too scary. (And BlackBerry was another one, by the way.) So I'm doing this and I'm like, hang on a second, what if they do a phone and it's a combination of the Razr and the iPod, could that resonate? And I just put it out there. I said, it's possible. And there was a rumor of the iPhone coming out.

Ben Thompson • 33:31
So Apple did do a Motorola Razr with iTunes functionality. Did that actually end up, because that was a flop. And did that actually make people not as like more relaxed?

Horace Dediu • 33:46
Because we knew that it didn't run an operating system. It didn't have a developer API, there was nothing, no hooks in it. It was just an appliance. And as such, it was like a feature phone. And that was not interesting. We had been talking and pounding the table on smartphones already since 2001. Remember, when I joined, we had a communicator. We had Symbian, Series 60. We had the interfaces. We had all picture phones, music, etc.

Ben Thompson • 34:20
I was a user as well.

Horace Dediu • 34:22
And I had done the numbers, and by 2005, people were burned out on smartphones. Because the projection was like this, but it was more like this. It wasn't growing as much as you thought it would. And so a lot of people said, especially the top management was like, "you guys are very enthusiastic about the software stuff, but it's just not working out. We're going to double down on hardware."

So there was a lot of burnout. So, but I kept looking at the phone at Apple and I suggested, hey, what if this thing scaled anyway? Like I said "what if they could sell as many as 50 million?" That was my provocation. And people were like, dude... I was essentially taken aside and told, tone it down. First of all, you're not doing yourself any favors by being so provocative. You're just going to lose credibility. My boss, who's a great guy he just took me aside and said, just don't do that. You know, it's bad for you.

Ben Thompson • 35:22
And this is like 2005, 2006, around then?

Horace Dediu • 35:25
Well, already 2006, because the iPhone was rumored. It wasn't out, but it was like, if you're going to have iPod success and you're going to do this crap phone with Motorola, you're probably thinking, maybe they're going to do something interesting beyond that, because we knew they could, in theory, do something.

We didn't see the touch interface, but we saw maybe like a scroll wheel or something. You know, Tony Fadell was running the thing. So, bottom line is, when it finally came out, it was January 2007. It came out and was not for sale, but it was on stage. And I was so excited. And I said, this is unbelievable.

I remember running into the office the next day. Usually you socialize at lunch hour, sitting in the cafeteria, talking to your friends and asking them what do they think about this? And most people just said, oh, it doesn't look that interesting. aspects of it were copied. There were copies from here and there. There are other people that do touch. You know, a stylus has been around for a long time with BlackBerry also doing amazing things with keyboard and so on and so on.

So there was a lot of cynicism and sort of not really interesting. I said, man, it's running OS X, it was running a full operating system. And I said, this is going to get developers working on it. But again, the other thing, the other head fake from Apple was that Steve Jobs said they're not going to put any apps on this thing unless Apple write them. I was anticipating far more than even was being talked about. And for that reason, it was just super frustrating. Anyway, I left in 2009. But by then, Nokia were still not following Apple.

Ben Thompson • 37:13
How is that possible? Like even two years on, this device is out there.

Horace Dediu • 37:19
Because it still didn't have distribution. And this is the thing that consumed everyone following the iPhone in the beginning. It's like they had one launch partner. It was initially Cingular, became AT&T. Don't forget that the old AT&T had nothing to do with this AT&T. It was just a rebrand of Cingular, which was a crappy, small, not very small, it was maybe second tier [operator.]

Ben Thompson • 37:47
Verizon didn't want to do it. Apple did this again and again. Verizon was number one.

Horace Dediu • 37:50
Verizon was number one. Absolutely. But Verizon was in CDMA. But the thing is that it was a crappy network and they didn't have a lot of points to sale. They didn't have distribution. and everybody said this, you need 500 network operators to saturate the global market, right?

And how fast are you going to be able to obtain distribution was the question. And so they're so cantankerous. You know, Apple is known as being "my way or the highway."

Verizon said no for years. Nokia was like, this is not going to fly. These guys are, if anything, they're naive. Don't forget, by the way, there's a separate story on how BlackBerry dealt with the iPhone. There's a movie about it, by the way. Everybody should watch it. But basically, everyone had the similar responses: that this is not kosher.

This is not the way things are done in this business. It's all about relationships with operators. It's about getting shelf space. It's about getting salesmen in the store who are bribed effectively with a commission to tell you what to buy, effectively yank the phone out of your hands and give you another one. So this was a very dirty business at the street level.

Ben Thompson • 39:19
So do you know what was the first what was the first article of mine that I think you ever linked to? It was about precisely. No, no, you don't need to know. I know because it was very formative to me. That's what I'm going to tell you. It was basically about talking about this was how distribution worked.

And what Apple changed about the whole thing was that customers actually switched networks for the iPhone. And it was doing just sort of a traditional sort of business school analysis of and pointing out the power shifted to instead of distribution to the buyers. Basically, what I ended up writing about for 13 years now is demand mattering more than sort of the supply bit. But it was the exact same thing. That's why you linked to it. You are you are already on board with it.

Horace Dediu • 40:04
But it was also the thing that resonated for me personally. Not that I knew something about the phone. Mostly I knew how big it could get. I knew that there were billions of people, many more billions than used PCs, which was by far the most dominant influence in technology.

Most people oriented themselves, like even Gruber and others who were Mac first and then all these accessories. But I knew the phone would be a couple of zeros more. That was number one.

Number two, there was this problem of the incumbency, which were all the phone makers, who were so far from understanding what the software dynamics of platforms were. By the way, platform theory was developed by Microsoft. They pretty much invented the whole idea.

Ben Thompson of the Stratechery interviews Horace on the Stratechery Plus Podcast to discuss Horace's journey to become an influential tech analyst: early career in research, business school under Clayton Christensen, and his time at Nokia during the rise of the iPhone. 

The conversation further explores Disruption Theory in the context of both smartphones and AI, why Christensen misjudged Apple, and whether AI could challenge today’s tech giants. It also marks the launch of Dediu’s new paid service Asymco One and reflects his continued conviction in Apple Inc. at its 50-year milestone.

From the initial product launch until the end of 2012, AT&T has activated 72 million iPhones. Verizon began selling iPhones four years after AT&T and managed to activate 26 million since. Sprint began nine months after Verizon and has activated 8.5 million.

In proportion of their subscriber bases, the activations are shown in the following graph.

 

I identified the reported iPhone activations with blue areas while the sum of green and blue areas represent total subs at the end a the given year.

I also took the liberty of forecasting 2013 data in order to try to estimate T-Mobile's contribution.

The method used was to look at the percent of total subs that each operator has been activating. Accounting for the limited sales period for Sprint in 2011, the sales patterns are consistent across the carriers. The longer the product is available, the higher the activation rate.

Therefore I estimated that in 2013 T-Mobile USA will sell about 10% of its subs base an iPhone. That would make its contribution to iPhone sales about 3.4 million.

It would also imply US sales among the top operators of 53 million iPhones in 2013.

That itself is 17% of 320 million subs.

So perhaps it's time for Apple to celebrate. This year, after six years, Apple will have completed entry into its first major phone market. The rest of the world will not be as quick.

[Kaoru] Kato, president of NTT DoCoMo Inc., said that the firm would want to add the iPhone to its lineup of serviced smartphones if it could form a mutually beneficial contract with Apple, Inc.

Apple requires that carriers servicing its devices sell a fixed amount per year. Katō said that his company could handle such quotas if iPhones accounted for approximately 20%-30% of its overall smartphone sales.

When thinking about an iPhone launch, especially with a new operator, the crucial question is what is the minimum order quantity (MOQ). Some of the iPhone production is sold direct (as in the case of orders coming from Apple's online store) but the majority of units are sold via operator who order in batches.

This issue came to light when Sprint's order was leaked in late 2011.  I discussed the order size at the time and put it in context. I concluded that Sprint MOQ was on average 7 million/yr., ramping with 4, 6, 9 and 12 million over a four year period.  I concluded that this was not a particularly aggressive gamble.

Data published since then shows that Sprint actually sold 6.3 million during the first year, well ahead of my expected minimum order of 4 million and above even the expectations for the second year of sales. So far then Sprint and Apple gauged minimum demand quite accurately.

I also showed that the Sprint MOQ was probably indexed off their sub base. I suggested that, based on subs data at the time, Sprint was committing to roughly 13% of its subs buying an iPhone every year. This was indexed off the data showing that 17% of AT&T subs were buying iPhones every year and 10% for Verizon. (I also assumed that this run level would be ramped over time).

The updated totals for the 12 months ended October 2012 are 19% of AT&T subs purchased an iPhone, 12% for Verizon and 12% of Sprint. The performance is shown in the following graph:

Which leads us to think about how the MOQ for the iPhone is calculated. If we assume Sprint and Verizon performance is typical it would imply that an operator like DoCoMo would be required to purchase iPhones at the rate of about 10% to 12% of its sub base each year, modulated to some degree by a ramp.

NTT DoCoMo had 60.7 million subs in September 2012. 10% is about 6 million. Is Mr. Kato's quote above of 20%-30% of smartphone sales consistent with this?

In an earlier interview (in July) Mr. Katō also stated that the target for smartphone sales in the year to March 2013 was 13 million. 30% of that would be 4 million units.

This suggests that the iPhone MOQ for DoCoMo is only about 6% of subs. (4 million) Perhaps this is the basis of negotiation for an iPhone deal. Apple may have held out for 10% subs/yr. with Sprint on the basis of performance of the iPhone in the US but might be willing to settle for 6% subs/yr with DoCoMo, at least for the first year.

The MOQ figure as percent of subs for China Mobile would also be an interesting point of debate.

 

Nokia announced 4.4 million Lumia smartphones were shipped in Q4. That's about 14 million since the Lumia line was launched a year earlier. It isn't however nearly enough to replace the lost sales from Symbian. One year earlier Nokia shipped 19 million Symbian phones in the fourth quarter and the year before 28.3 million. The history of smartphone sales from Nokia is shown below:

I repeated the forecast I drew up in February 2011 when the platform switch was announced. That forecast was based on the company stating that 150 million Symbian phones would still be shipped. Symbian fell far more rapidly than I (and Nokia) expected and to date only 98 million have shipped. The last quarter's 2.2 million seems to be so low that it will be hard to imagine the platform lasting more than a few quarters.

My forecast for Windows Phone was 15 million (through Q4/2012) and the 14 million actually shipped is not far off. However, note that the sequential growth into the fourth quarter was lower than the same period last year. For the holiday quarter Nokia received almost no boost. If there is reason to be optimistic it's that there wasn't a decline in overall smartphones into Q4.

The overall result is that Nokia remains in an operating loss status and it's going to be very hard to recover. No phone vendor has successfully recovered to date. The company managed to book a €50 million one-time payment for IP rights (presumably from RIM) and is sustained by royalties and platform support payments from Microsoft. But even so it's barely breaking even.

The prospects for Windows Phone may be improving however. Operators in the US continue to talk about it. We don't have a split for AT&T's push this past quarter and estimates suggest that 80% of smartphone from AT&T were still iPhones but Verizon will also push the platform and there are suggestions it's doing well in Germany. HTC has also launched some WP flagship phones and may have had a good December as a result.

That translates into steady progress. But the growth of Android and iOS continue as well. Windows Phone needs to continue to persevere in adverse conditions for years to come. The Finns know a thing or two about that.

During the last 12 months 31 million American phone users abandoned the use of feature phones. During the last 24 months over 60 million switched. Over 550k users are switching every week and this rate of switching has not changed much since late 2009.

Some of this switching has to do with demand for smartphone services but some of it is also due to a decreasing supply of non-smart phones. The shelf space being allocated to smartphones is nearing 100%. My single sampling of a Wal-Mart store shows the following data:

Looking at individual carriers, AT&T ranged one feature phone and 7 smart SKUs. Verizon's ratio was 2:8 and T-Mobile's was 4:5.

T-Mobile has been lagging in smartphone adoption and as they transition in 2013 it's possible that the AT&T ratio of 12% shelf space dedicated to feature phones will become the norm for the US. And as the US goes, the world will follow.

With shrinking shelf space comes an accelerated decline in the product category. It may not come in 2013, and perhaps not by 2014 but it's quite possible that by 2015 the last feature phone will make its appearance in the US.

The second quarter showed continuing growth for Android with 19 points of share growth from a year ago. Only Windows Phone showed a gain y/y in share up 1.6 points to about 3%. In the same time, Bada lost half a point, iOS lost 2.1 points, RIM lost 7.2, Symbian 11.4.

The result is shown in the graph below:

I also show a "before-and-after" pair of pie charts which show the difference in smartphone platform market share from the same quarter three years ago. Android went from 3% share to 67% while Symbian went from 41% to 4% and RIM went from 19% to 5%. iOS increased its share from 13% to 17%.

If this trend continues Android could reach 50% of all phones sold in a few years. That's a run rate of 200 million per quarter. And it's likely that 100 million of those will be shipped by Chinese vendors.

However, looking at the global picture can also miss some important trends in local markets. Had one looked at the global smartphone business in 2005, the conclusion would have been that Symbian would be the dominant platform in perpetuity.

What affected the global market was a change in the US: the launch of iOS and thereafter of Android. The US, a smartphone backwater until then, became the most vibrant market and today it's the most penetrated and has the highest ratio of smart to non-smart of any of the major regions.

The curious thing about this vast market is that it's still not truly open. There are technology and political reasons why some platforms are permitted to sell in one region or not. The iPhone is not available on either the largest Chinese operator or on the largest Japanese one. It's largely absent from India because of distribution (i.e. subsidy) and much of South America. Even in the US, the iPhone is still, after five years, not available on one of the top four operators and has only reached another less than a year ago.

What intrigues me is what would the market look like if distribution were not an issue. What if there was equal choice to all buyers. We can't test this question directly but we can ask. But there is some pattern we can look at in the US data. Thanks to recent revelations at the Samsung vs. Apple trial we can see the effect of increasing distribution in the US.

The data on smartphone market share by carrier can be blended with data from carriers about iPhone activations (which are a proxy for sales, see note below) to give a more precise figure of market share in markets where iPhone participates.

For example, when the iPhone was only available on AT&T, one could measure iPhone market share vs. the global smartphone market, or the US smartphone market or within AT&T alone. Some assumed that the AT&T share would be reduced once the product would become available on Verizon or other US carriers. However there was no appreciable drop. Share in Q4 2010 was 63% at AT&T and it was 63% a year later after the iPhone was available for four quarters at Verizon.

So the share of iPhone within those operators which carry it tells a story independent of distribution.

The following graph shows the share of the iPhone vs. Samsung in the market defined by its availability. (I.e. the volumes of smartphones sold by AT&T throughout the time period, Verizon Q1 2011 to end and Sprint in Q4 '11).

The share of iPhone thus defined shows a slight decline but it's an overall number that is remarkably resilient as distribution increases and is remarkably high overall. Note that globally, the iPhone gets only about 17% share of smartphones--a value that has not varied greatly since mid 2009.

So at least in the US, on carriers where it's available, the iPhone is holding on to a significant share. In a global market it's expanding distribution but not yet covering the world. As a consequence it's keeping up with overall market growth and staying between 17% and 20% share.

The big question is what will happen if and when its availability matches that of Android in terms of points of sale. Or even that of BlackBerry or Symbian. Is America a different market from the rest of the world? It was different in being isolated while Symbian roamed globally. It was different in being a launch platform for BlackBerry and then iOS and then Android. But now that iPhone is beginning to be widely available there, will it be exceptional in how it rewards Apple?

Note:

1. Activations data can be seen next to Apple's testimony of US sales in the following graph. Note that more phones were sold by Apple than were activated in total of the life of the product. 86 million sold and 80 million activated. This implies that an analysis based on activations undercounts the iPhone. 

Verizon has been the first source of data on iPhone sales for Q4. They reported 4.2 million iPhones sold. The first quarter of Verizon iPhone sales had 2.2 million units, followed 2.3 million in Q2 and 2 million in Q3. The total for the calendar year came at 10.7 million.

The total for AT&T during the first three quarters has been 9.9 million. If we assume the same 2x sequential increase in Q4 relative to Q3 as observed by Verizon we obtain an estimate of 5.4 million iPhone for AT&T.[1]

The quarter also saw the addition of Sprint to the US iPhone distribution network. Sprint is rumored to have committed to buy 30.5 million iPhones over the next four years. My estimate for the first year was 7 million, placing first quarter sell-in at about 2 million.

An approximate total for Q4 US iPhone activations results in 11.6 million. The following chart illustrates these estimates:

Notes:

1. AT&T reported that smartphone sales during October and November totaled over 6 million units. Assuming only 2 million for December and a 70% iPhone mix yields 5.6 million units.

In the recently posted US Smartphone Landscape I used comScore's data to paint a picture of the growth of smartphones in general and the shape of the mobile platforms in the US. The source was survey data measuring the installed base. If we compare the installed base sequentially, we can get the increase (or decrease) of a particular platform. Comscore reports monthly but we can also summarize the data at a quarter-by-quarter basis.

There is another source however for the US market, at least for the iPhone: operator activations. They report iPhone activations, shown below.

Can we use activations together with installed base data to learn something about the market? Yes, with some caveats.

First, it should be noted that install base should account for all sorts of devices. They could be new, old or hand-me-downs or purchased used. Changes in install base would come from addition of new devices but also from devices being discarded and users leaving the platform. Activations on the other hand include units new units but also those which have been re-activated after initial sale because they were either sold or given to other users. As far as I know operators do not report "net" activations so lost users are not included.

When the formulas are combined[1], what we get is the change in installed base is equal to Activations minus "discarded" iPhone, where "discarded" are both iPhones put aside in favor of a new iPhone or put aside in favor of another phone.

Since we have installed base change data and we have activation data we should be thus able to derive the number of iPhones being "discarded" or put out of use every quarter as the difference between activations and change in installed base.

That allows the following chart to be built:

The green, dark blue and orange areas are given inputs and the light blue area representing discarded phones is derived.

This is an interesting (new) piece of information. What it suggests is that at least in the US the discard rate, i.e. number of phones being discarded over number of new phones is about 50% (56% on average over seven quarters.)

It's a rate I find surprising because I expected more of the phones to be re-used. But more surprising is that it leads to some surprising and possibly implausible behavior at AT&T.

If you look at the last three quarters, you can see that Verizon activations are very nearly equal to the increase in install base. As all Verizon users are new, they are certainly not replacing iPhones, so the green bars next to the yellow bars imply that all those new users are Verizon users. But that means that all the activations through AT&T were to replace existing phones and that AT&T only added a bit more than one million iPhone users in nine months.

In quarters prior to Verizon's launch, the AT&T discard rate was a modest 60% on average and after Verizon launch it went to 81%.

What does it mean?

---

Note:

1. The following diagram shows the derivation of "discarded" units.

 

In Apple: For What It’s Worth Jeff Matthews asks a question "about the most disturbing pattern coming out of Apple’s earning release: the measly 1% year/year revenue increase at Apple’s retail stores".

He notes that prior to the drop, Apple stores were growing at 36%. Such a huge drop quarter on quarter seems suspicious and he thinks something is happening.

Something is happening.

To find out what, let's start with the revenue from Retail that Apple reports[1]

 

 

The concern is with that low growth between calendar Q3 last year and this year. That is being contrasted with the growth in the previous quarter (Q2) of 36%.

When seen as a chart, the explanation for a big change in growth is perhaps easier. The third quarter of last year was a boom for retail and the quarters that followed were more-or-less similar in sales level.

With this perspective, it's clear that there was a surge in sales during the last year which did not repeat this year.

But what's the cause for this pattern? If we know the cause can we predict if retail sales growth will increase or decrease?

Consider the following compound chart:

The chart shows three different quantities.

1. The original retail sales values in "hollow" bars
2. The growth in those values year-on-year (in a line chart)
3. A "proxy" candidate for retail growth explanation: the sum of US phone activations and in-store CPU units sold as a stacked bar chart.

The choice of proxy includes the blue bars which Apple reports as in-store "CPU units" and the US phone activations[2] coming from AT&T and Verizon[3].

We can see now that there is a strong relationship between iPhone sales growth and store sales growth. The Mac business is growing but not in the bursty way that iPhones are growing. The growth of US iPhones matches the growth in (US mostly) Apple retail. This should not be a surprise.

The bursty nature of iPhone means that store growth varies just as dramatically. I highlighted that during the period of Q4 2008 to Q1 2010, Apple store revenue grew at an average of 7.3% but following the "big bang" of the iPhone 4 launch they grew at 79% over the subsequent five quarters (because the comps were easy).

In the latest quarter the growth dropped as there was no launch of a new iPhone to top the big bang of a year earlier. Even so, store revenues actually increased by a slight amount.

Knowing that the comp with the year before was so tough the surprise isn't that the growth slowed, it's that there was any growth at all.

If iPhone as a cause for growth in retail is to be believed, then how hard can it be to forecast retail growth in the future?

Notes:

1. Apple does not submit this information to the SEC but reports it (exclusively I believe) during the earnings conference call. Transcripts are available on seekingalpha.com but fortunately they are recorded as well by Gary Allen at ifoapplestore.com.
2. I used US data for the iPhone as most of Apple stores are in the US. The global pattern is similar.
3. I had to estimate Verizon units used during the last quarter as they have not been reported yet. I used a similar ratio between AT&T and Verizon as for the last quarter.

The Wall Street Journal reported that Sprint Nextel made a "multibillion-dollar" gamble on the iPhone. This is based on information that Sprint committed to buy 30.5 million iPhones over the next four years.

Wall Street Journal reporters calculated that the deal is worth around $20 billion on the basis of iPhone ASP during the last quarter (about $650). That Sprint would get that price is possible but not necessarily correct as there is likely to be some discount and the ASP Apple receives includes accessories.

But the "gamble" is more than the deal value. The way it's being reported is that Sprint bet the company on being able to sell this many iPhones. So naturally we have to ask: how hard can it be to sell 31 million iPhones?

First, note that the order is over a four year period. It's also not likely to be linear, with volumes accelerating over time. If I estimate a ramp where in year one the commitment is for 4 million, year two 6, year three 9 and year four 12 million we get a total of 31 million. Can Sprint sell this volume?

To get an idea we can look at the sales rates for the other US operators. I built a table of iPhone sales by Operator last July. The data is shown in the following chart:

What is interesting is to see the number of iPhones sold in a given time frame as a percent of subscriber base. I chose to measure a year's worth of iPhones where I extrapolated Verizon's volumes from the six months reported so far.

The ratios are that Verizon sold iPhones at the rate of about "10% of its subscriber base per year". AT&T has been selling at the rate of about "17% of its subs per year". If we average these two we get about 13.6%.

So if we assume that Sprint can sell iPhones at about the same rate as Verizon or AT&T (as a percent of their user base which was 51.1 million) we get about 7 million iPhones per year.

That's right in the middle of the range it needs to get to 31 in four years [4,6,9,12]. I charted the projection on the following chart:

So the gamble Sprint is taking is that they will be able to sell iPhones at the same rate as Verizon and AT&T.

How is this risky?

The deal seems to be inline with what is known about the product's popularity and the pattern of purchasing and upgrades that US consumers have been exhibiting for a few years.

As with AT&T and Verizon, volumes ramp up over time. As with AT&T, users are loyal and they upgrade regularly. As with Verizon, there is competition from Android and Blackberry. As with both, payment is expected up-front with payback over the duration of contract length. As with the others, there will be incentives to keep churn down.

If anything the riskiest thing for Sprint would have been not to do the deal at all. Indeed, we'll get to see the effect of that option on T-Mobile.
