At this time, I would like to welcome everyone to the Sun Microsystems fiscal year 2007 fourth quarter results conference call.
All lines have been placed on mute to prevent any background noise.
After the speakers' remarks, there will be a question-and-answer period.
(OPERATOR INSTRUCTIONS) I would also like to inform participants today's conference is being recorded.
If you have any objections, please disconnect at this time.
Thank you, ladies and gentlemen, I would now like to turn the call over to Mr.
Bret Schaefer, Vice President of Investor Relations for Sun Microsystems.
Thank you.
Bret Schaefer - VP, Investor Relations
Good afternoon.
Thank you for joining the Sun Microsystems quarterly conference call.
I'm Bret Schaefer, Sun's Vice President of Investor Relations.
With me today is Jonathan Schwartz, Sun's CEO; and Michael Lehman, Sun's Chief Financial Officer and Executive Vice President, Corporate Resources.
The purpose of today's call is to discuss the results of Sun's fiscal year 2007 fourth quarter which ended on June 30, 2007.
During the last hour, we published a copy of the operations data analysis sheet with nine quarters of financial and operations information, including the quarter just completed.
If you have not received the announcement or the detailed financial data sheet for any reason, or you wish to hear the replay of this conference call, you may log on to our web site at sun.com/investors.
We posted slides you can view on the web which accompany our prepared remarks.
These slides may be viewed at the same URL, sun.com/investors.
After the prepared remarks of our call today, we will devote the remaining time to Q & A.
During the course of this conference call, we'll be making projections and other forward-looking statements regarding expected future financial results and business opportunities.
Our actual future results may be very different from our current expectations.
We encourage you to read the 10-Ks and 10-Qs that we file periodically with the SEC.
These documents contain a discussion of the risks facing our business, including factors that could cause these forward-looking statements not to come true.
We do not currently intend to update these forward-looking statements except as required by law.
In addition, during the course of the conference call, we may describe certain non-GAAP financial measures which should be considered in addition to, and not in lieu of, comparable GAAP financial measures.
Please refer to the operations analysis posted on our web site at sun.com/investors for the most directly comparable GAAP financial measure and related reconciliation.
Now, let's get to the financials.
Sun's total revenues for the fourth quarter of fiscal year 2007 were $3.835 billion, an increase of 0.2%, as compared with $3.828 billion in revenue reported for the fourth quarter of fiscal year 2006.
Total gross margin was 47.2% of revenue, an increase of 4.4 points over the gross margin for the fourth quarter of fiscal 2006.
Total R&D and SG&A expenses were $1.472 billion, a decrease of $206 million year-over-year.
In the fourth quarter of fiscal 2007, we recorded a $56 million tax provision.
GAAP net income for the fourth quarter of fiscal year 2007 was $329 million or diluted earnings per share of $0.09, as compared with a net loss of $301 million or a net loss of $0.09 per share for the fourth quarter of fiscal year 2006.
Q4 products revenues totaled $2.492 billion, a decrease 1.3% year-over-year.
Within products revenues, computer systems products revenue was $1.853 billion, an increase of 2.3% year-over-year.
Data management, or storage products, revenue was $639 million, a decrease of 10.4% year-over-year.
Q4 services revenue totaled $1.343 billion, up 3% year-over-year.
Within services revenue, support services revenue was $1.024 billion, up 3.9% year-over-year.
Revenue from professional services and educational services totaled $319 million, an increase of 0.3% year-over-year.
We ended the quarter with a cash and marketable debt securities balance of $5.942 billion and generated positive cash flow from operations of $564 million in Q4.
In Q4, we announced a $3 billion share repurchase program.
During Q4, we repurchased 38.8 million shares, which equates to approximately $200 million.
Shares were repurchased at an average price of $5.15.
You will note that our outstanding shares for the quarter decreased by 20 million as the share repurchase was partially offset by the issuance of shares under our employee equity plans.
With that, I'll turn it over to Jonathan.
Jonathan Schwartz - CEO
Great, thanks, Bret.
Hello, everyone.
This is a great day for Sun and I want to congratulate the entire team and partner community on a milestone quarter.
I'm proud to say that we exceeded our profitability targets, delivered industry leading innovation in all our core businesses, and yet again, grew new opportunities in the future.
For FY '07 overall, we're pleased to report revenue growth of 6.2% and SG&A and R&D expense reduction of 3.7% and an increase in gross margin of over 2 full percentage points to 45.2%.
This progress is a direct result of the continued hard work and effort put in by all our employees and partners, and on behalf of the entire management team at Sun I want to let you know that your efforts are, in fact, paying off.
So thank you.
Now, on to Q4.
We put a stake in the ground just over a year ago when we announced our growth plan, emphasizing our commitment to deliver at 4%, at least 4% operating margin in Q4.
I'm very pleased to report that we exceeded the target with an 8.5% operating margin on a GAAP basis.
We met and we exceeded our plan across a diversity of metrics, namely the steady execution and financial discipline around operating expenses and the increasing value of our innovation to our customers, as gauged by gross margin performance and revenue growth across key products and services.
I'd like to take a moment to walk through each of these.
On the operating expense front in Q4, we effectively decreased our SG&A and R&D spending by 12% from a year ago, while retaining employee bonuses and performance-based compensation.
We're by no means done here, and rest assured we view our progress in FY '07 as the first of many steps to streamline Sun.
It's important to note that we achieved these reductions while increasing our focus and commitment to the R&D pipelines and road maps at the core of our business.
Coming into FY '08, we have the strongest product road map in the history of the Company, driven by new virtualization features in Solaris 10, now with nearly 9 million licenses distributed to date, to our upcoming Niagara 2 processors and a full line of commodity systems based on SPARC and x64 platforms and an even stronger foundation of core innovations in software, in silicon design, networking and storage, all delivered from a streamlined and more efficient Sun.
Now to gross margin, an important gauge of customer confidence.
With gross margins hitting a six-year high in Q4 of 47.2%, we are clearly seeing a growing payoff from Sun's R&D investments, evident both in the 225% year-over-year billings growth in our energy-efficient T1000 and T2000 systems and 39% year-over-year growth in our Sun Fire x64 systems.
Our commodity servers as a category grew billings 14% year-over-year in FY '07, and our margin profile continued to grow as we shift more highly configured systems.
In Q4 you began to see the real impact of Sun's virtualization investments with support for Solaris 10 containers, and as of this month, support for bundled virtualization, giving customers the ability to buy fewer, but more richly configured systems and storage on both SPARC and x64 platforms.
I'd like to emphasize all this is achieved without the license fees required by other operating systems.
We clearly see Solaris and its core virtualization properties as opening a world of new opportunity beyond computing.
With the Sun Fire X4500, which I've spoken as Thumper, you've seen it set the foundation for a new line of data warehousing appliances based on general purpose computing and open source operating systems.
We shipped nearly 20 petabytes of Sun Fire X4500, again, Thumper, in Q4 and are now on an annual billings run rate of $100 million.
With Sun's Gigabit Ethernet technology, also known as Project Neptune, and Magnum, the 3456 port InfiniBand switch that we recently introduced at the core of our new high performance Sun Constellation System, you can see the leverage of our talent pool and technology, enabling entry into adjacent markets.
We'll amplify this in the coming year with a focus on the open Solaris Project Crossbow, a technology to virtualize network traffic that's entirely unique to the open Solaris and Solaris communities.
These platforms in combination position Sun to grow more value and opportunity, leveraging a common base of R&D and a rapidly expanding marketplace, with Solaris at the core of our computing storage and networking products and our open source software offerings continuing to lower the cost of joining the network.
All of this said, our commitment to innovation and R&D is unwavering, and our commitments are clearly paying off.
As for our revenue results for the full fiscal year 2007, you'll note on slide 6 we saw a significant growth from new products, with outstanding growth in systems based on our UltraSPARC Chip Multithreading, with billings of approximately $550 million in FY '07 and nearly $200 million alone in Q4.
Additionally, in FY '07 our Netra Telco servers grew billings 38%.
Our embedded Java business grew 60%, and our Identity software business grew 36%.
Our Services group continues to execute with almost 9% growth in FY '07, punctuating the contribution of Solaris to higher value added Professional Services in conjunction with our systems offerings.
This is definite progress and a sign that innovation is selling, however, our top line results weren't as strong as we'd like them to be.
Overall, the results namely reflected weakness in the U.S.
in storage and in certain legacy systems.
Going into the new fiscal year, we'll be focused on accelerating new product adoption in the market to deliver growth across a broader spectrum of offerings.
We're focused on improving sales performance in the U.S.
as new opportunities emerge on everything from handsets to high performance computing installations.
In storage, we're committed to moving through a difficult transition as we move to Solaris-based systems and remain focused on the compelling storage road map we have, including the Sun Fire X4500.
As I said earlier, today is a good day, a great day in the life of Sun.
It's an important milestone to deliver on our commitments for FY '07 and to make significant progress toward achieving our goal of at least 10% operating profit for all of FY '09.
We have our work cut out for us, and we look forward to a new year, focused on growing share, attracting new customers, forging new partnerships, and gaining even more leverage in our operating model.
This all in an effort to strengthen our position in network computing and to attract opportunity with our innovation at the core of the network.
With that said, I'd like to pass it over to my officemate, Mr.
Lehman, for more details and specifics.
Mike?
Michael Lehman - CFO, EVP, Corporate Resources
Thanks, Jonathan.
We are clearly pleased with the leverage that exists in our overall business model and with the progress we made during FY '07.
On an annual basis, we improved GAAP operating income by nearly $1.2 billion over the prior year, improved our gross margin by just over 2%, and generated more than $950 million in cash flow from operations.
It was a solid year in terms of execution.
We improved the underlying business model and we have set the stage for further improvements in FY '08.
While we have a lot more work to do, we have made measurable, and we believe, sustainable progress.
There are a few things relative to the quarter's performance that I want to be sure you understand.
Currency has been a hot topic for some of our listeners and been profiled in competitors' announcements.
While imprecise at best, we estimate that net revenues were favorably impacted by around 2% based on exchange rate movements.
This was partially offset by a higher level of operating expenses.
We estimate that the overall net impact of exchange rate movements on the bottom line in Q4 was less than $0.01 per share.
Our linearity was well within normal ranges throughout the quarter.
We did not experience the kind of fall-off in demand at the end of June that we experienced in March.
Having said that, as you look at our revenues by geography, you will note that the U.S.
revenues were down just under 2% on a year-over-year basis in Q4.
For the most part, that continues the trend we saw in the March quarter.
A number of vertical markets in the U.S.
are doing well, most notably financial services, government and telco.
Overall, revenue growth in EMEA, at just under 2%, reflects growth in central and northern European countries, Iberia and the southern and eastern European countries somewhat offset by continued softness in the U.K.
and Italy.
The year-over-year growth in Asia Pacific revenues, at just under 2%, reflects very strong growth in Australia, Asia South, Korea and India offset by a continued decline in Japan.
One area that we did not make further progress on was our channel inventory in the U.S.
Outside the U.S., channel inventories decreased as expected.
In the U.S., one of our major partners ordered an increased level of products as a specific investment aimed at growing their revenues.
At the end of June, our worldwide net channel inventory was slightly more than $250 million, which reflected a $10 million sequential increase rather than a modest decrease as we had anticipated going into Q4.
During the next few quarters, we intend to continue to work with our partners to decrease the overall levels of inventories.
We intend to change our channeled business practices to a sellout model later in FY '08.
Gross margins were clearly the highlight of our income statement in Q4.
The gross margin did come in above our estimates.
Product gross margins were up 3.1 points sequentially.
Frankly, lower component costs were the largest element of the increase.
We also had an improved mix of software, as well as a beneficial mix of commodity CMT and more richly configured x64 systems while continuing to manage our pricing actions relative to the competitive landscape.
Service gross margin increased more than 2 percentage points sequentially, principally due to the benefit of higher revenues and a fairly stable cost structure.
Turning to operating expenses, our total R&D and SG&A expenses were basically flat sequentially.
However, there are a couple things beneath that which you should understand.
As many of you know, we closed on the sale and lease back of an East Coast facility in late June.
We recognized a one-time gain on that transaction of approximately $39 million in Q4.
That amount is reflected as a reduction of SG&A expense in Q4.
We did incur higher incentive compensation expense during Q4 related to the sequential revenue increase, and due to achievement of our quarterly operating income targets.
Those increased expenses somewhat offset the gain from disposition of the facility.
The income tax provision for the quarter was $56 million, in line with our estimates.
I would also point out that we generated approximately $560 million in cash flow from operations during Q4.
We continue to focus on improving our cash conversion cycle.
We ended the fiscal year with approximately $5.9 billion in cash and marketable investments.
This strong cash generation ability and liquidity positioned us well for continued growth.
We expect to generate an increased amount of cash from operations in FY '08 compared to FY '07.
Looking forward to fiscal year '08, we expect the following to be reflected in our annual business model.
We expect revenue growth to be in the low to mid single-digits on a year-over-year basis.
Based on the timing of product introductions, we expect revenue growth to be a bit higher in the second half of the year, relative to the first half.
We expect gross margins to be in the range of 43% to 46%.
We expect total operating expenses, excluding any potential restructuring charges, and based on current exchange rates, to be in the range of $5.6 billion to $5.8 billion.
We expect amortization of intangibles to be in the range of $250 million to $275 million.
We expect approximately $225 million to $250 million of stock-based compensation expense.
We expect net interest income of approximately $200 million to $225 million.
We expect the full-year tax provision to be approximately $200 million to $250 million.
As noted earlier, during Q4, we repurchased approximately $200 million in stock in the open market.
During fiscal '08 we intend to continue to repurchase stock as a part of our previously announced $3 billion buyback program.
Jonathan has mentioned earlier that we are still working to achieve increased levels of profitability, and we are still committed to achieving an annual operating margin of at least 10% of revenues on a GAAP basis for the full fiscal year 2009.
Our goal is to achieve at least 8% operating margin in Q4 of FY '08.
We believe this level of operating margin will balance the need for increased investments to grow our business and allow us to set the stage for achieving our fiscal year '09 goals.
We are pleased with the results of Q4 and FY '07.
We recognize we have to continue to lower our cost structure and are evaluating ways to do that.
You should take some comfort in both our stated resolve and the demonstrated progress that we achieved in fiscal '07.
We will be hosting a financial analyst meeting in New York City at 8:00 a.m.
on September 5 this year.
Details will be available through our investor relations team and our investor relations web site.
At that meeting, we will have a more in-depth discussion of our growth and cost initiatives for the new fiscal year, as well as discuss any potential changes to our capital structure.
With that, I will turn it back to Bret.
Bret Schaefer - VP, Investor Relations
Thank you, Mike, and Jonathan.
Before we begin the question-and-answer session, I'd like to request that each of you ask just one question consisting of one part.
This way, we hope to get most of the questions in the queue today.
If there's time remaining, we'll be happy to take your follow-up questions.
Brooke, will you please start the question-and-answer session?
Operator
Thank you, ladies and gentlemen, we will now begin the question-and-answer portion of today's call.
(OPERATOR INSTRUCTIONS) Please wait one moment for the first question, please.
Our first question comes from Laura Conigliaro of Goldman Sachs.
You may go ahead with your question, please.
Laura Conigliaro - Analyst
Yes, a couple of questions.
Notable was the absence of any commentary about your expectations for the September quarter.
Might we expect normal seasonal progressions, at least on the revenue side?
Also, can you talk a little bit more about your views of your storage business?
How are you going to address what really has been continued weakness and disappointment?
You obviously have the Solaris storage goal, but that's going to take a while to ramp up.
Have you given any more thought to more radical measures, either in cost or divestitures as far as storage is concerned?
Michael Lehman - CFO, EVP, Corporate Resources
Laura, it's Mike Lehman, I'll comment on the first one.
I am not sure what normal seasonality is in this macro economic environment.
So one of the reasons we wanted to focus on the entire fiscal year is to give a sense of the overall revenue growth we expect to see, which is low to mid single-digits.
Obviously, there's a level of seasonality that is typically associated with our businesses and we should expect some of that.
But we're more focused on looking at the annual results at this point.
Jonathan Schwartz - CEO
And Laura, this is Jonathan.
You know, when we look at our storage business, we're really looking at a few separate categories.
I think we're running the business somewhat as we expected on the archive side of the business, or the tape side, which is the result of the StorageTek acquisition.
That continues to play out for us reasonably well.
The low end, we think, is being completely redefined by the types of NAS offerings and data warehousing appliances that we're now building with Thumper and with Solaris.
We see no cessation of that business.
There's a lot of proprietary vendors that are going to try to build proprietary technology there.
We think we have a very good and compelling advantage, and given that Thumper within in the marketplace for under three quarters now and we're already at $100 million run rate, that's actually a pretty good ramp and we're pretty pleased with it.
The rest of the business, we have an OEM business, we've got a low end disk business.
Frankly, the OEM offerings weren't as strong as we would like, we know we have some work to do there, but from our vantage point we're pretty comfortable executing on the IP that we've been building and believe that's where our focus will be going forward.
So we're eyes wide open, we're aware of some of the execution challenges, as well as some of the strategic challenges, but feel like we have the right foundation to really March forward.
Bret Schaefer - VP, Investor Relations
Next question, please?
Operator
Thank you.
The next question is from Ben Reitzes of UBS.
You may go ahead, please.
Benjamin Reitzes - Analyst
Yes, good afternoon.
Thanks.
In talking about the fiscal year, maybe you could just talk a little bit more about how you're going to get -- how you might bridge us to 10% in '09?
It looks like by the end of the year you need to be at least at 10%, and then in order to kind of have that climbing throughout four quarters, would you be open to any incremental cost-cutting measures or whatnot to achieve your goal?
Michael Lehman - CFO, EVP, Corporate Resources
So it's Mike Lehman.
I'll start with that.
We believe that the path to the fiscal year '09 10% operating income continues to have three main drivers.
One is revenue growth, second is increased gross margins over time, and the third is lower operating expenses.
We are going to be working on all of them.
And our view is that the -- at least 8% operating income target in Q4 of FY '08 will set us up well to achieve that.
Jonathan Schwartz - CEO
Just to amplify on that point, we're always looking at balancing -- taking advantage of our market position with trying to fuel new market opportunities.
We want to make sure that we're not biasing simply deliver tactical near term results, but instead we're setting the right foundation for the long term.
Bret Schaefer - VP, Investor Relations
Next question, please?
Operator
Thank you.
Our next question comes from Andrew Neff.
You may go ahead, please.
Andrew Neff - Analyst
I just want to amplify, on slide 16, can you maybe elaborate on some of the points you were alluding to before?
The year-over-year growth in some of your core growth initiatives, and again, there's lots in those numbers.
The x64 numbers are down, the total server is down, and I know there's lots of -- that's units versus revenues and things like that.
Can you address what's going on there?
What's going on behind that and what you're doing to address that?
Jonathan Schwartz - CEO
You bet.
I think just as the market saw a decline of tower servers, which were eventually replaced by rack level servers, our view is that the volume of rack level servers will eventually be somewhat displaced by much more highly configured and virtualized larger scale systems.
And that's both on the system side, as well as on the storage side.
The good news is that plays to our strength.
We have a tremendous amount of intellectual property there, both on the system storage design, as well as with an operating system that knows how to scale up quite well.
So I think we definitely saw a bit of a slowdown in the U.S., specifically, but we also saw an increase in revenue and margin dollars available to us, because we have more and better, frankly, higher scale systems than the rest of the marketplace, whether that's on the blade side or on the core computing platform side.
We don't view this as in the least bit discouraging, I think our view is that in a way, the market's going to play to our strength now, and we can reflect that with better returns going forward.
Virtualization in the near term looks like it has a depression, or a depressing impact on units, but our view is it actually contributes to demand for more richly configured systems, that's what we got, that's where we think we can grow revenue margin and ultimately units, as well.
Andrew Neff - Analyst
So just to clarify then, what you're saying there is that's not reflecting CPUs, that's reflecting just boxes in that chart?
Jonathan Schwartz - CEO
Very much so.
Bret Schaefer - VP, Investor Relations
Next question, please?
Operator
Thank you, our next question is from Richard Farmer of Merrill Lynch, you may go ahead, please.
Richard Farmer - Analyst
Thanks.
Jonathan, and Mike, on the 47% operating margin, you talked about the factors, I wonder if you could talk a little bit about how those are or are not sustainable going forward?
Presumably the component pricing is going to be less favorable in the second half.
What about the software mix and the other factors you mentioned?
How should we think about those going forward?
Jonathan Schwartz - CEO
Given there's no way I could possibly have suggested we'll hit 47% operating margin, I'll turn that over to Mike to answer.
Michael Lehman - CFO, EVP, Corporate Resources
I would clarify, we were talking about gross margin.
Thank you.
Richard Farmer - Analyst
Sorry, gross margin.
Michael Lehman - CFO, EVP, Corporate Resources
47% operating would be nice.
So the factors that I mentioned, the one that obviously we don't have control over is cost.
And certainly we always see cost reductions, those tend to go in cycles.
I think it's pretty clear from looking at the Q4 results that there was a pretty healthy dip in memory prices and we and others took advantage of that.
We don't expect that the same rate of cost decreases will continue every quarter, so there was probably a little bit of a one-time effect there.
It's a little hard to quantify.
The other things that we mentioned, the pricing discipline, the mix, the performance of our products, the richer configurations that Jonathan just referred to, improving results in our storage offerings over time, those all are generally speaking net positive for us.
So that's why when I step back and we look at the business for the fiscal year, fiscal year '08, we're now talking about gross margin range at 43% to 46%, which is slightly up from what we had projected for fiscal '07.
Bret Schaefer - VP, Investor Relations
Next question, please?
Operator
Thank you.
Katie Huberty of Morgan Stanley.
You may go ahead, please.
Katie Huberty - Analyst
Thanks, good evening.
Given your confidence in the product portfolio and guidance for revenue growth in fiscal '08, how comfortable are you cutting operating expenses again before you fully understand the adoption rate of some of the new products on the road map?
Michael Lehman - CFO, EVP, Corporate Resources
I think we have a fairly good understanding and are fairly comfortable with the adoption rate of the new products.
All that said, we also believe there's yet more efficiency we can garner from the system, and we are going to continue streamlining to the extent we can.
We're going to make prudent decisions about that because we want to build a foundation for the long term not just for the near-in.
I think we have our eyes on the right set of issues and challenges to move forward.
Bret Schaefer - VP, Investor Relations
Next question, please.
Operator
Thank you, Harry Blount of Lehman, you may go ahead, please.
Harry Blount - Analyst
Thanks, Mike, I want to come back to the September question, I heard your answer earlier.
As I look at historic seasonality, I see the product revenues typically down 18%, and services typically down 5%.
What do you see in the macro environment that could cause you to be better or worse than those numbers and related to that September question, do you expect to be able to be profitable on a GAAP basis in earnings in the September quarter?
Michael Lehman - CFO, EVP, Corporate Resources
Let me be really clear, I don't want to be and I'm not going to be forecasting quarterly revenues and profit during this call.
Certainly, there are seasonality factors that historically we have looked at and understand.
I think we all are looking at the U.S.
economy and looking at what's going on in the markets and trying to understand what the impact is on capital spending and how that relates to our customers, et cetera.
So we are planning the business on an annual basis.
We, obviously, have views of a quarterly basis, there's going to be some seasonality associated with that.
But our basic view is that we are doing some work during the year to get us ready to achieve higher levels of sustainable profitability toward the end of the year and going forward.
Bret Schaefer - VP, Investor Relations
Next question, please.
Operator
Thank you, our next question is from Lou Miscioscia of Cowen and Company.
Louis Miscioscia - Analyst
Okay, thank you.
Jon, let's go back to virtualization for a second.
At the analyst meeting, I did ask you about this and your comment was that customers would actually increase their IT budgets due to taking use of the power that was there.
Obviously, systems have been weak the past two quarters now and it looks like for the projection for the next two, they're going to be weak also, do you still think that customers are going to start to accelerate?
And when should we start to see it in our revenue numbers?
Jonathan Schwartz - CEO
I guess I don't view our systems business as being weak.
I think we demonstrated growth, and, frankly, demonstrated growth throughout the year, and especially year-over-year.
I think what we're going to see is customers looking toward systems vendors that know how to scale.
That's both on the network side, the systems side, as well as on the storage side and have a full complement of offerings that actually make it happen, as opposed to kind of band-aid solutions after the fact.
When we double the speed of our computers, people don't buy half as many.
When we double their utilization, we don't expect them to buy half as many, either.
We actually expect them to buy more.
They just may come in a different set of packages, in a different wrapping of sheet metal.
I think we expect there to be continued growth in demand for computing capacity, storage capacity and bandwidth, certainly.
We plan on fully participating in that with our own intellectual property.
I'm not sure I have any greater lens into what the specific changes are and when they occur.
But in general, our customers tend to see IT as a weapon and tend to use it as a vehicle to differentiate themselves.
They're looking to buy more technology at this point, not to invest in less.
Bret Schaefer - VP, Investor Relations
Next question, please.
Operator
Thank you.
Bill Shope with JPMorgan, you may go ahead, please.
Bill Shope - Analyst
Okay, great.
Thanks.
Looking at the product mix within your SPARC-based systems, can you discuss whether higher end systems continue to benefit the overall mix and margins in the quarter, and if so, how does this rank with the other factors you mentioned for the overall gross margin profile?
Jonathan Schwartz - CEO
I think we saw a rise in the very high end systems, the enterprise class systems.
There was some sloping off on the mid-range sides.
That's a balance, depending upon where customers are in their growth cycles, it moves one way to the next.
The single most important leading indicator for the demand of systems from Sun, as well as increasingly systems from other vendors related to Sun is the adoption of Solaris, and as we continue to see that being deployed in the highest scale data centers, or even in very large scale high performance computing facilities, I think we tend to look at that as, again, a great leading indicator of opportunity in front of us.
But this is a marathon, not a sprint.
These are adoption waves that roll in waves; they don't change the marketplace instantaneously.
And I think we have enough of a lens on the future right now, just with the 9 million licenses we've seen, to suggest there's going to be an ample opportunity on the back end of it.
Bill Shope - Analyst
Okay, great, thank you.
Bret Schaefer - VP, Investor Relations
Next question, please.
Operator
(OPERATOR INSTRUCTIONS) Thank you.
Next question is from Toni Sacconaghi of Sanford Bernstein.
Toni Sacconaghi - Analyst
Thank you.
I wanted to revisit the margin question.
Mike, I think you had said the majority was associated with components.
Often in the past you had provided a bridge of the forces at work on gross margins.
Could you help us with that and what contribution you do believe was from components?
I presume that's DRAM, which was down so dramatically, and then just consistent with that, if there really are other forces other than components that you think are ongoing, how come your guidance range, the midpoint of your guidance range is actually lower than your gross margins recorded in fiscal year '07?
Michael Lehman - CFO, EVP, Corporate Resources
I will not be providing a more mechanical or mathematical bridge.
I've given you all a highlight of what the key issues were.
I did say that component costs were the principal driver of the sequential change in product gross margin.
A lot of that was memory, absolutely.
There certainly are other components that decreased, and we expect continued component cost decreases going forward, perhaps not in the magnitude we saw in the fourth quarter.
There are a lot of factors that I mentioned that play into the products gross margin, including the mix, the software mix, the product mix, the storage mix, et cetera.
A lot of those we have some control over and some we don't, and certainly, as I mentioned, the discipline and the practices we have around managing the pricing and the competitiveness of our offerings.
So there's a lot of factors to play.
For those of you that know us and our tendencies toward predictions, we want to manage the Company based upon reasonable revenue growth rates, reasonable gross margin percentages, and put discipline in the system and ensure that we take cost out of the system to help us achieve our operating income target.
So the fact that we give a gross margin range that is a little bit wider and a little bit higher than what we gave last year should give people some insight that we feel there is some potential upside, but we are going to continue to manage the Company and plan the Company conservatively.

Next question, please.
Operator
Thank you.
Our next question is from David Wong of A.G.
Edwards.
David Wong - Analyst
Thank you very much.
[As far as] your fiscal 2009 guidance, do you reckon that you can get down operating expenses?
will they drop down in absolute dollars in '09 over '08, or is it a question of just reducing the percentage of OpEx?
Jonathan Schwartz - CEO
I think we believe there will be absolute spending reductions, that there is ongoing efficiencies we will identify through existing IT projects and other operational activities that will bring the total dollars spent down.
David Wong - Analyst
And similarly your projection assumes you continuously improve gross margin?
Jonathan Schwartz - CEO
At this point our projection doesn't assume we can increase gross margin.
I think our strategic agenda is to do exactly that.
One reason why we were able to rather fully enjoy the benefit of the operations team executing with better margins on a -- or better costing on memory, is we tend to shift fairly highly configured systems and have an operating system that knows how to deal with very large pools of memory.
We're going to continue to build out the R&D portfolio with technologies that add value to customers and our assumption is if we do a good job of expressing that value we'll be rewarded in the form of higher gross margin.

Brent Bracelin of Pacific Crest Securities, you may go ahead, please.
Brent Bracelin - Analyst

Had a follow-up question around virtualization.
Looking at your support services, it looks like it's slowing there.
How should we think about virtualization and declining server units impact on the growth in support services?
Jonathan Schwartz - CEO
I think whatever slowdown we might see now from the impact of virtualization I think is probably amplified, if not entirely dwarfed, by a slowdown in the broader macro economy, especially in the U.S.
I think going forward, we believe having more differentiated virtualized systems means we'll have access to more of the market.
If we have access to more of the market, my belief is we can win more than our fair share.
When we do, not only will our systems revenue and units rise, but we expect that to be reflected on the services side, as well.
As we sell virtualized systems, customers tend to buy integrated racks, as opposed to piecemeal components that they try to integrate on their own.
Again, that just gives us more bites at more apples and ultimately a higher margin profile, as well.
Bret Schaefer - VP, Investor Relations
Next question, please.
Operator
Thank you, next question is from Harry Blount of Lehman.
Harry Blount - Analyst
Hi.
Just a quick follow-up.
Mike, you gave a lot of the FY '08 expectations.
I don't recall hearing any specific guidance around the CapEx or depreciation.
Michael Lehman - CFO, EVP, Corporate Resources
That part is true.
I actually don't have a specific number with me, and that's probably one of those things we'll give a little bit more clarity on in the September meeting.
Harry Blount - Analyst
And then related to the financial statements, your warranty reserves dropped about $40 million year-over-year.
Was there any other significant changes or reductions in absolute reserves or allowances that enhanced the FY '07 results?
Michael Lehman - CFO, EVP, Corporate Resources
No, and in fact the fact that warranty reserves are lower reflect the increased quality of the products and services that we are offering, so that's a good thing.
Harry Blount - Analyst
And then lastly, you mentioned you had a sell-in benefit in the quarter and that you are moving to sell out accounting.
Can you help quantify what that sell-in benefit was?
Thank you.
Michael Lehman - CFO, EVP, Corporate Resources
The only thing I will do is reiterate that net worldwide channel inventories are up about $10 million sequentially.
We expected them to go down modestly during the quarter.
And the principal reason that they went up was that one major channel partner took a real specific action and intentionally bought a little bit more inventory than we had expected as they were driving their Q4 revenues and promotions.
It's not a big change, not a dramatic change.
We're still heading down the same path we've been talking about for the past year, to work with our channel partners, reduce the inventories, reduce the inventories to levels that can ensure that they ship to customers as is needed, that reduces carrying costs in the overall business model and that's a good thing for ourselves and our partners.
Harry Blount - Analyst
Thank you.
Jonathan Schwartz - CEO
And we're thrilled with channel partners that love to buy from Sun.
Bret Schaefer - VP, Investor Relations
Next question, please.
Operator
Thank you.
Richard Gardner from Citigroup, your line is open, please.
Richard Gardner - Analyst
Thank you so much for taking the question.
I was hoping that you could maybe address what looks to be roughly a 30% decline in traditional UltraSPARC units in the quarter, and also maybe give us a sense of how customers are responding to the new SPARC 64 product that you just came out with, the M series, at the very high end.
Thank you.
Jonathan Schwartz - CEO
So we are seeing a bit of a resurgence in our customer base right now, and, frankly, that's a derivative of two things.
Number one, that we have a new set of product offerings with Fujitsu that allow us to play in a very different segment of the marketplace than we have historically.
The response to those products has, frankly, been great.
We're very happy with the performance we're seeing; it's actually above our own expectations.
I think with respect to unit volumes, we're obviously looking to grow those unit volumes going forward, but we're also looking to grow the number of cores we ship.
And as we move to more highly threaded and highly multicore systems that's going to have a short-term depressing effect on unit volume.
To be a bit of a broken record here, the single best leading indicator of our SPARC business going forward is the extent of the adoption of Solaris, and given that we saw increasing momentum, incorporation of certain technologies from Solaris and other operating systems really broadening the overall pool of available customers for Sun, we're continuing to be very optimistic about not only the future for Solaris, but the future of systems built with Solaris at their core, and SPARC is certainly the flagship of those.
Richard Gardner - Analyst
Jonathan, if I could ask one follow-up.
Do you believe that customers are viewing the new jointly developed products with Fujitsu, the M Series, as a replacement?
Or say the E20K, or do you believe that this is more of an incremental opportunity for Sun?
Jonathan Schwartz - CEO
I think it's hard to tell.
It's probably a little bit of both.
We're seeing some folks decommission mainframes and replace them with M9000s.
We're seeing folks that never expected to see the level of demand that they are seeing in their transactional systems want to move to M9000s.
We're seeing new super computing facilities that like having a teraflop in a box, and we're just about the only company out there that can provide that.
So it's always tough to tell.
I think if you're running a system at that scale, you're unlikely to be a start-up in Silicon Valley or a social networking company.
So there's a little bit of a market that's been predefined in that way, but even there, there's a fair amount of movement in those markets and there's always new opportunity for us to go after.
Bret Schaefer - VP, Investor Relations
Next question, please.
Operator
Thank you.
And our final question comes from Keith Bachman of Bank of Montreal.
Keith Bachman - Analyst
Thanks very much.
Jonathan, I was just wondering, you're calling for a revenue acceleration if you look out over the course of the next fiscal year.
I was hoping you could highlight the product areas you think are going drive the revenue acceleration.
Related to that, should we be thinking about this as mostly a share exercise, that is to say gaining share in your product categories given the commentary that you've made about the macro backdrop?
And then, finally, if I can sneak one more in.
At the analyst day you commented that there was a slide that suggested about 20% of the customers through the U.S.
direct sales force were new to the brand, or were new customers to Sun.
Given my question on share, I was hoping you could update us with any anecdotal evidence you have on share gains that you think you've experienced during the recent quarters.
Jonathan Schwartz - CEO
You bet.
Why don't I start on the share side?
This is going to be a little repetitious, even on the call.
But the single best leading indicator of the adoption of Sun Systems opportunity is the adoption, first and foremost, of the network, and secondly of Solaris on that network.
We're seeing a broad scale adoption of the network, largely at this point, driven by mobile handsets and social networking as much as it is by enterprise IT.
Secondarily, we're seeing a very aggressive adoption of Solaris.
Some 70% of that adoption of Solaris is now occurring on IBM, HP and Dell hardware, and that's all upside opportunity for those vendors, and ideally an avenue for improved partnering activities, as well as an opportunity for Sun, as we deliver higher scale innovation that allows folks to take developed systems and put them into deployment.
If you look at Solaris, you'll see us having planted very successfully at this point the seeds of a growing storage business and that's what led to the amplification of our Thumper business, from literally a standing start some eight months ago to about a $100 million dollar run rate business is a pretty good ramp, and I'd like to believe we can continue to project that.
If you look at Crossbow, which is a new community forming in the open Solaris world, that's what allows you to take a general purpose server like a Niagara or a Niagara 2 platform and actually build network devices out of it.
And that allows people to compress their existing systems and, again, give Sun yet more market opportunity.
And then on the computing side, the numbers that some of the analysts will post say it's about a $50 billion, $55 billion market which looks relatively stagnant over the past 10 years or so.
But I think if you look under the covers, you'll see it's actually a bit of a boiling cauldron of competitive activity, lots of shares, swaps, one-year to the next and we'd like to believe we're on the front of taking a lot of share.
But also as the world moves more toward the network, we think there's a broader market to be had going forward.
Across the board, I think is the -- what will grow Sun will be the core innovation, and the value of that innovation for our core marketplace, and so long as our core market continues to look to technology as a vehicle to grow and differentiate their business, we think the value of our business will only increase.
