Good day, ladies and gentlemen, and welcome to the Q4 2018 Marvell Technology Group Ltd. earnings conference call. At this time, all participants are in a listen-only mode. Later, we will conduct a question and answer session and instructions will follow at that time. If anyone should require assistance during the conference, please press star then zero on your touch-tone telephone. As a reminder, this conference is being recorded. I would now like to introduce one of your hosts for today's conference, Peter Andrew. Mr. Andrew, you may begin.
Thank you. Good afternoon, everyone. Welcome to Marvell's fourth quarter and fiscal year 2018 earnings call. Joining me on the call today is Marvell's President and CEO, Matt Murphy, and CFO, Jean Hu. Before I turn the call over to Matt, I wanted to remind everyone that certain comments today may include forward-looking statements which are subject to significant risks and uncertainties and which could cause our actual results to differ materially from management's current expectations. Please review the cautionary statements and risk factors contained in our earnings press release, which we filed with the SEC today and posted on our website, as well as our most recent 10-K and 10-Q filings. We do not intend to update our forward-looking statements. During our call today, we will make reference to certain non-GAAP financial measures.
A reconciliation between our GAAP and non-GAAP financial measures is available on our website in the investor relations section. With that, let me turn the call over to Marvell's President and CEO, Matt Murphy.
Thank you, Peter. Good afternoon to everyone on the call. The completion of fiscal 2018 marks my first full fiscal year as the CEO of Marvell, and our performance over this period demonstrates that Marvell is successfully transforming itself into a much more capable and competitive company, one that delivers much greater value to customers, employees, and shareholders. Since I joined Marvell 19 months ago, we have increased our focus on our three core markets: storage, networking, and connectivity. We've also added greater discipline into our product development process, retooled and reinvested in our sales force and go-to-market strategies, and continued to drive efficiencies in our new business model. Our fiscal 2018 results clearly show that these actions are paying off. Fiscal 2018 year-over-year revenue from our core businesses grew 7%.
You may recall from our investor day a year ago that our stated goal was to grow faster than our core end markets, which at that time were estimated to grow 6%. I'm proud to report that we exceeded that goal. I'm also pleased that this growth was broad-based, with storage growing 8%, networking growing 1%, and connectivity growing 14%. It is worth noting that our networking business, excluding legacy, grew 7%. I'll talk about that in a minute. For fiscal 2018, non-GAAP gross margins increased over five percentage points from a year ago to 61.4%, exceeding our target of 60%. Non-GAAP operating margin increased to 25.9%, up over 11 percentage points from a year ago. We're making steady progress towards our long-term target of 30%.
Finally, in the 10 months leading up to the Cavium announcement, Marvell returned $647 million to shareholders, which is 130% of our full year FY 2018 free cash flow. By all measures, our results were impressive. Now turning to our Q4 results. Revenue in the fourth quarter was $615 million, above the midpoint of the guidance we provided back in November. Non-GAAP gross margin reached another all-time high of 62.3%, which reflects both the value we deliver to customers and the great work our team has done to drive down costs. We see continued tailwinds to our gross margin due to a richer mix of storage and networking, new product ramps that are accretive to gross margins, and continued improvement in optimizing our manufacturing cost structure. Our non-GAAP operating margin for the quarter was 27%. Our non-GAAP EPS grew 45% year over year to $0.32 per share.
Moving to our core businesses. Storage continued its strong performance, exceeding our expectations and growing 3% sequentially. As I mentioned earlier, storage grew 8% for the full year, driven by strong growth in SSD and continued traction of products targeting the enterprise and data center markets. Q4 was a record quarter for our SSD business as we continue to see strong demand for our broad family of SSD controller solutions. During the quarter, we ramped NVMe-based products for new tier 1 client and cloud customers. These engagements, while early in their lifecycle, demonstrate that our continued traction in the NVMe transition. We look forward to sharing more details on our progress in the coming quarters. Our HDD business also experienced stronger than expected results in the fourth quarter, driven by growth in the enterprise and data center markets.
We remain excited about this business as customers implement new cutting-edge technologies that Marvell's SOCs help to enable. These new technologies are driving significant aerial density gains, which continue to make HDDs a very attractive solution for nearline storage in the data center market. Overall, we're happy with the performance of our storage business. Our Q4 and fiscal 2018 results demonstrate this business is firing on all cylinders. Moving to networking. Our networking business grew both sequentially and year over year. We saw strong demand for our refresh switch, PHY, and embedded processor products, which grew largely in line with their expectations during the quarter. However, this growth was partially offset by our legacy networking products declining more than expected. We saw forecasted demand for legacy in Q4 push out into the first half of fiscal year 2019.
Looking into the first quarter of fiscal 2019, we expect our overall networking business to grow in the mid to high single-digit range year-over-year, driven by growth of our new products. For those of you attending the upcoming OCP Summit, we will be showcasing our end-to-end storage and networking solutions for the data center market. We will be highlighting our brand new PHY product we announced earlier this week, a high-density transceiver supporting 16 ports of 15G PAM4 signaling for gearbox and retimer applications, aiding in the transition in hyperscale data centers from 25G Ethernet up to 400G Ethernet. In addition, we will also be showcasing our data center switch portfolio, including our newest product, a 1 terabit switch, fully optimized for 10 gigabit data center applications, providing the lowest power of any such product on the market today.
Our networking business continues to gain traction in the marketplace with strong design win momentum in the enterprise campus, data center, and four and a half and 5G base station markets with our refresh portfolio. With the upcoming addition of Cavium's processing solutions to our portfolio, we have a unique opportunity to bring truly differentiated solutions to our combined customer base. Our connectivity business delivered strong results for the fiscal year, growing revenue 14% year-over-year. We've been working to refocus this business on the high-performance market, and this past quarter, we announced our leading 802.11ax family of products. This innovative technology delivers an industry-best implementation of the new 11ax standard, bringing customers up to four times greater capacity, support for the greatest number of users, symmetrical uplink and downlink performance, and greater coverage in all deployments. Marvell has a strong 16-year track record in this business.
Because we deliver superior performance reliability, we are a top choice for enterprise access points in automotive customers and are already gaining design win momentum with our 11ax solutions. We've repositioned this business for success, and I'm very proud of the engineering and management teams for their focus and perseverance. Before I close, I want to give a quick update on the Cavium acquisition. Since announcing the Marvell Cavium transaction on November 20th, both companies have been actively working on integration planning. We've launched an integration team comprised of representatives from both companies, set up a steering team to ensure strong governance, implemented a robust project management process, and kept employees at both companies updated on our progress. Regulatory approval is progressing with the HSR antitrust process complete and MOFCOM and CFIUS reviews underway. Shareholder meetings for both companies are scheduled for March 16th.
We continue to anticipate this transaction will close in mid-calendar 2018. Our planning progress to date has been laser-focused on developing detailed plans on synergies, both COGS and OPEX. I'm extremely confident we can achieve our previously announced synergy targets of $150 million to $175 million within 18 months of closing, and $200 million beyond 18 months. Since the transaction was announced, I've had the opportunity to spend time with the Cavium team in customer meetings, business plan reviews, organizational strategy meetings, and integration planning. The feedback from the customer base, in particular from the leading companies in cloud computing, wireless infrastructure for four and 5G, and enterprise, has been overwhelmingly positive. The quality of the people inside Cavium in BUs, engineering, sales, and other corporate functions have been truly impressive.
I'm very proud of how the collaborative leaders from both sides have been in integration planning, with the mindset being, "How do we truly create a best-in-class new company from the combination?" Overall, I want to thank the team for their commitment and contributions, both this past quarter and over the entire year. We've made amazing progress, and I look forward to what we're going to accomplish together in the new fiscal year. Now I'll turn the call over to our CFO, Jean Hu.
Thanks, Matt, and good afternoon, everyone. I'll discuss the highlights for our fourth quarter and fiscal year 2018 and provide our current outlook for the first quarter of fiscal 2019. Revenue in the fourth quarter was $615 million, about middle point of guidance we provided in November. Our core business of storage, networking, and connectivity grew 8% year-over-year. Storage accounted for 53% of revenue and grew 4% year-over-year, driven by the success of our SSD products and continued growth in the enterprise and data center segment with both our SSD and HDD solutions. Networking accounted for 25% of revenue and grew 5% year-over-year, driven by our new switch PHY and embedded processor product. Connectivity had a solid quarter and accounted for 14% of revenue and grew 31% year-over-year, driven primarily by growth in high-end voice-enabled and home streaming devices.
Finally, other products accounted for 8% of revenue, which was about $2 million better than we expected due to last-time buy activity. GAAP gross margin for the fourth quarter was 60.7%, and the non-GAAP gross margin was 62.3%, a record level for Marvell, an increase of 4.5 percentage points from last year. GAAP operating expenses were $319 million, higher than our guidance, primarily due to the settlement of 2015 security class action claim for $72.5 million during the quarter. Non-GAAP operating expenses was $217.6 million, consistent with our expectation. GAAP operating margin was 9%, and the non-GAAP operating margin was 27%, versus 20% a year ago, as we were successful in driving leverage in our model. GAAP earnings per diluted share was $0.10, and the non-GAAP earnings per diluted share was $0.32. For fiscal 2018, we delivered a non-GAAP EPS of $1.19, up 80% versus fiscal 2017.
Let's now turn to our balance sheet. We ended the quarter with over $1.8 billion in cash on hand and no debt. Cash flow from operations was $120 million. Excluding one-time payment of $72.5 million to settle the security class action claim, we generated approximately $193 million cash from operations. In Q4, we distributed $30 million to shareholders in dividends. For fiscal 2018, we returned approximately 130% of free cash flow to shareholders. As a reminder, we have not been in the market repurchasing shares due to the pending Cavium transaction. I want to now take a minute to talk about our capital allocation philosophy in light of the announced merger with Cavium. As we mentioned when we announced the deal, we expect the combined company will generate a strong and consistent cash flow. After the deal closed, our gross leverage ratio, excluding synergy, is expected to be 1.7 times.
We plan to use our combined cash generation to rapidly pay down the debt associated with the transaction to get to a gross debt to EBITDA leverage ratio in a 1x to 1.5x range. Our board and the management team structured this transaction in a way to provide a high level of financial flexibility and maintain investment-grade financial profile, while also allowing an opportunity to return cash to shareholders. Returning capital to shareholders is a very key element of our financial policy. Based on strong and consistent cash flow generation of the combined company, we expect to revert back to returning 50% of our free cash flow to shareholders while two quarters post closing. In summary, fiscal year 2018 was an important year for Marvell. We executed well to deliver both top-line revenue growth and a significant higher profitability.
Before we turn to guidance, I want to highlight a new revenue accounting rule change. We have adopted the new revenue recognition accounting standard effective at the beginning of Q1 fiscal 2019. This changes our revenue recognition criteria for distribution customer sales from sell-through to sell-in accounting. This change does not impact how we conduct our business, and we don't expect this change to have a meaningful impact on our revenue. In addition, we have evaluated the major provisions of the Tax Cuts and Jobs Act. We do not expect the Tax Act to materially impact Marvell's effective tax rate currently. As a reminder, we are working on the integration plan of Marvell and Cavium. We'll provide our update of the combined company tax rate after close of the transaction. Turning to our first fiscal quarter of 2019 guidance.
As a reminder, the fourth quarter is a normal 13-week quarter versus the prior quarter, which had 14 weeks. We expect our total revenue in the range of $585 million-$615 million. At the middle point of our guidance, it would represent a 2% decline sequentially and a 5% year-over-year increase for the whole company. Our core business of storage, networking, and connectivity is expected to grow 6% year-over-year. We expect our storage revenue to decline 6%-8% sequentially due to normal HDD seasonality. This would represent a slight decline year-over-year. We expect our networking revenue to grow sequentially and in the mid to high single digits range year-over-year, driven by continued momentum in our new product ramp.
We expect our connectivity revenue grow in the mid-teens sequentially, stronger than normal seasonality, primarily due to a customer earlier than normal product build, which would typically occur over Q2 and Q3 period. We expect other revenue to decline high single digit year-over-year. We are pleased that our expected growth margin will be in the range of 62%-63% despite an unfavorable product mix with a larger contribution from connectivity and the revenue seasonality in Q1. We expect our GAAP operating expenses to be approximately $250 million-$260 million, and non-GAAP operating expense to be approximately $215 million. We anticipate GAAP income per diluted share in the range of $0.22-$0.26, and the non-GAAP income by per diluted share in the range of $0.29-$0.33. With that, we'll now open the line for Q&A. Operator, we'll take the first question, please.
Okay, ladies and gentlemen. At this time, if you have a question, please press star, then the number 1 key on your touch-tone telephone. If your question has been answered or you wish to remove yourself from the queue, please press the pound key. To prevent any background noise, we ask that you please place your line on mute once your question has been stated. Our first question comes from John Pitzer with Credit Suisse. Your line is now open.
Yeah. Good afternoon, guys. Congratulations on the solid result. Matt, maybe the first question from me, just going back to the legacy networking business. Can you help us understand what % of networking that now represents? Given that you saw pushouts from the fiscal fourth quarter into the fiscal first half, can you just give us a little bit more color of what drove those pushouts and why you have confidence that they're now going to fall in the first half of the new fiscal year?
Sure. Yeah. Thanks, John. Happy to answer the question. The answer to the first part, which is the % of networking today that's in legacy, is around 15%. Last year, it was in the 20% range. As new products have ramped up, that %, that legacy continues to go down, but it's about 15. As I mentioned in my remarks, the core portion where we have our new product ramps occurring, came in pretty much in line with what we thought. We saw very strong year-over-year growth there. That was on track. Within legacy, the pushout, it was kind of interesting. It was really driven by one product area, which was our NPU product area. It was pretty specific, and it moved out from Q4, and it'll be consumed within the first two quarters of fiscal 2019.
My understanding of the pushout is it's related not so much to end demand weakness as much as some issues around component supply within that particular customer on that particular box. It happened during the quarter. We see it selling through or resuming production. Sort of absent that, I'd say overall it was pretty close to what we thought. I will say, as a lot of companies have reported, communications has been a bit choppy for everybody. We would sort of give some color that enterprise and wireline has held up pretty well. Things that are exposed to carrier and telco and others have been more choppy. In aggregate, just to help everybody understand, I'd say it's primarily driven by kind of one product, one issue, we certainly see demand recovering on that one.
That's helpful. Matt, maybe as my follow-up, on the SSD controller business, I think one of the questions that I get asked often by investors is, the HDD controller market ended up being mostly a merchant supplied market. When you look at the SSD controller market, guys that are providing NAND are clearly trying to move up the value chain. I think last week, Western Digital launched a family of SSD products with their own internal controller. Our work would suggest that hyperscale customers don't want to move in that vertically integrated direction. I'd be curious on your thoughts on how you think the merchant versus the in-house market plays out in the SSD controller market over time.
Okay. No, got it, and I'll give you my perspective. I'd say even going back a year and a half plus ago when I joined, I think this same issue was top of mind as we started talking to investors about SSD and our plans there. I think there's been an effort across a number of the producers of NAND to have their own internal solutions. Some of those have been successful, some of those haven't. We've been operating in this world for some time now, I think you should expect, at least for the time being, that you'll see a mix of Marvell solutions in the market as well as some of our customers doing some of their programs internally. I'd say that's not necessarily a change.
It's how we've been operating, and we've been able to, I think, execute and grow really well, through this cycle, and we certainly still feel very good about our outlook over the coming year. I think you sort of would take the words out of my mouth. I think you're right on the where the puck is going. In particular, trends we see within the data center is that one of the models is for more control over that design by the cloud hyperscale companies. It's a great partnership opportunity for Marvell to step in and get much closer to the development of the end equipment and then work with NAND partners to enable the whole solution. That business model is very much alive and well along with our merchant efforts.
I'd end by saying, my job and the team's job is really to continue to innovate in this area, invest ahead of the curve, and really eliminate reasons why our customers might even want to think about doing these things internally. I think our team's doing a good job of that. I think that'll be my comments there on SSD.
Yes. To add to what Matt just said, yeah. It is the design cycle of SSD products is quite long, right? Really long cycle. We're actually very encouraged and pleased with all the design wins we're working on. We don't see any issues there. Our team is really focused on the design wins and working on those wins to ramp up in the next several years.
Jean, just maybe as a housekeeping on the accounting change from sell-through to sell-in, what % of your revenue does that cover? You made the comment. You don't expect a material impact to revenue. Was that a fiscal year comment, or is that also true for the fiscal first quarter? We've seen other companies in the quarter where they make that change have a positive revenue impact. I'm just trying to make sure your comment was not just a fiscal year comment, but also for the fiscal first quarter.
Yes. First, you're right, is Marvell's distribution revenue. It's about 20% of our total revenue. More importantly, a very significant portion of that revenue actually is demand fulfillment. When you think about Marvell's revenue really generated from distributor, it's very small, probably below 10% of revenue. Typically, our inventory in the distribution channel, it's about demand fulfillment and keep the operational flexibility. That's why we don't see much change on our revenue either for Q1 or going forward.
Perfect. Thank you, guys. Appreciate it.
Thanks. Our next question comes from Christopher Rolland with Susquehanna. Your line is now open.
Hey, guys. Congrats on a great quarter here. On networking, a key customer of yours has been talking up their new campus switch product. I think they described it as being the fastest-growing product line in their company history. Perhaps you can talk about what that means for Marvell and that opportunity there. As you guys size up networking, what do you think the biggest opportunities for fiscal 2019 are? Thanks.
Sure. Thanks, Chris. Yeah, a couple of comments. I think that particular announcement was really good for that company. It's going to be good for Marvell, and I think even maybe on a broader scale, it really lit a fire within the industry to drive this upgrade cycle in the campus area, which, as you've heard over our commentary for the last year and a half, that's really been an area where we've been very focused on a global basis to drive all of our new products that were refreshed into that segment. We do think that the enterprise, and the campus has a nice tailwind to it from that point of view, and we do think that that's certainly positive for us. I think that's going to be one factor as we look into 2019, per your question.
I think the other one really, I would say, in terms of design win activity that appears to have really picked up, and it sort of comes on the heels of a lot of the announcements that people were making at MWC, and with, I think, the sort of view that 5G is really alive and well and probably happening earlier than people thought. There's a tremendous amount of design activity going on there, and in our networking product line in particular, we're seeing very strong demand in our higher capacity switches, including our 10G switches, as well as our 25G switches that we had initially targeted for the enterprise data center. Those are now seeing very good design win momentum across that market as well.
When we look out to 2019, we see a mix of some resurgence in enterprise and campus, along with some new opportunities and new boxes being built to support the next-generation wireless technologies that are coming.
Great. On the SSD side of things, perhaps you talked a little bit in your prepared remarks about some hyperscale engagements. Any progress or details there? For SSD overall, I think you said that that would be exiting this year about 30% of storage. Did you track to that 30%? How do you see this as a percentage exiting fiscal 2019?
On the first one, I would not get very specific other than to say, we've had a lot of positive engagement in this hyperscale area for some time. That's continued. I would probably also say that in the meetings I've had now with the Cavium folks, with those types of customers, the level of engagement we're having is even at higher levels, probably within those companies than we've been engaged. I think it just presents an additional opportunity and validates the fact that that's going to be a key part of our comprehensive solution sell when we look at engaging deeply in the cloud. With respect to how did we do on SSD as a percent of storage, we set this bogey out there of 30%. We did have a record quarter in SSD, we were very pleased. We came very close to our 30%.
I wouldn't say it was 30.0, it was really darn close. Quite frankly, as we noted in our comments, because HDD also had a very strong quarter for us and performed above our expectations, probably the fact that HDD did a little bit better caused us to come in just slightly below our 30% target. That's one I really can't complain about because both businesses did better. We're not setting an official target at this point for ending fiscal 2019 at this time. We absolutely expect that this will continue in terms of the mix shifting from HDD to SSD in an environment where even HDD we can hold flat. Any growth we see in SSD, as a percentage, will be because of top line, not because we anticipate HDD decline to make up the difference. Hope that's helpful.
Perfect. Thanks, Matt. Congrats again to everybody.
Okay, thanks.
Thank you. Our next question comes from Craig Ellis with B. Riley FBR. Your line is now open.
Yeah, thanks for taking the question. Matt, I just wanted to turn it to longer-term matters. First, congratulations on the very strong fiscal 2018. Great job for the year. Looking at some of the growth rate benchmarks that you talked about, storage up 8%, networking, I think you said 7%. As you look at 2018, what are the gives and takes to growth in the business that would be in that mid to high single-digit range for a second consecutive year?
Sure. Yeah, Craig. I think, again, we were happy with the performance, as you know. We do see the momentum continuing. While we're not giving fiscal year 2019 guidance, we do believe that our thesis on storage remains intact and very sound, which is really continue to remix our HDD business, and add incremental enterprise and nearline type of revenue as client, has a secular decline in it due to the remix in SSD. Net-net, we're still sticking to our strategy, along with preamps, by the way, of keeping HDD flat as a goal. We're coming off a great Q4 in terms of SSD being a record quarter, and we certainly hope and anticipate that we'll see growth in that business again in fiscal 2019.
When you add those two, clearly you get something that's above flat when you look at growth rates, and we're optimistic we can keep growing that business. In networking, especially as legacy has come down and is a much more manageable portion of the total, I think that gives us more comfort that the strong momentum we see in our new products will have some runway and the headwind from legacy will be a little bit more diminished than we've had before. We think we can manage both of those. I think in summary, what I'd say is we see these two businesses for Marvell standalone as well as even when we combine the two companies, as really being a strong growth engine in terms of both top-line contribution as well as gross margin accretion.
Again, it's on the heels of new products and really important secular trends that are driving the need for more storage, higher bandwidth, data traffic management, more processing of data and more security of data. I think all these things, we see that thesis playing out and benefiting those two businesses that you mentioned.
That's very helpful. The follow-up would be, you made two comments I thought were interesting with respect to Cavium. One, the feedback that you're getting from customers, and then your high confidence in hitting previously stated synergies targets. I'm just wondering if you could elaborate on those a little bit further, to help us understand what you're seeing as you get closer to closing that deal. Thank you.
I'll comment on the customers. I'll give a point of view on synergies, and I'll also have Jean chime in on synergies as well, since we've been joined at the hip on this one to make sure that we execute to everything that we've committed. On the customer side, I've had the good fortune to spend a lot of time with Syed and the team, since really we got this thing announced. I'd say what's really resonating are a couple points, and this would be, I'd say, across a wide range of end customers, including top cloud hyperscale companies, top companies leading in the wireless infrastructure race, and also some of these companies that are leading the resurgence in enterprise and campus demand, both wireless and wired.
That is, we're able to come in and basically say, look, we are a scaled-up, innovation-oriented, fully focused on infrastructure supplier to you. Our primary focus in life as a company is to focus on being an infrastructure solutions provider. This scaled-up R&D budget that we now have, much more bulked up market cap and revenue, provides a lot of assurance to those companies that we have the scale and the strength to invest. We also have the technology, the technical capabilities, the people, the know-how, and trusted relationships coming in from both sides. It's resonating really well because we don't look like a company that's going through distraction right now. Even though we're going through an integration, it looks like to our customers, because this has been so positively received by both sides, it's really been a joint effort.
I think when the customers look out, they see a really a new, unique supplier to meet their needs. I'd say that that's hit kind of a home run across all the customers that I've met with. On synergies, just to give you a sense, we take this very seriously. Of course, the strategic rationale for this transaction we think makes a ton of sense. I told you that the customer reaction was very good, we also are just very focused on making sure that everything we've committed from a synergy point of view happens and is executed as well as we did as a standalone company when we did our own transformation.
I'm pleased to say, the level of detail that we have now on the different value drivers across almost every operation between the two companies on how synergy can be captured, I think is very well understood. There's strong ownership from the leaders of both companies at the VP level and up to go make it happen. Because of the way we're managing it, there's really, I think, just top-notch governance around the process. I think myself and Jean and others feel very good. Maybe, Jean, you want to give some color on how you think the synergies are going to be realized and how the process is going.
Yeah. I think it's really two things Matt mentioned. One is very detailed planning. Second is really accountability of the team. Team take responsibility. When you look at the synergy, we're very comfortable with the range of a synergy within 18 months. Bear in mind, a lot of synergy will rely on system integration and the ERP. From the shape of the synergy, you're not going to see much in the first 6 months. Once you get the integration of the system and the ERP, a lot of the synergy will happen between 9 to 12 months. I would say, we have a very detailed planning and the timeline of the synergy. That's really the comfort level we have about the synergy realization in the next 18 months.
That's helpful. Thanks, Matt. Thanks, Jean.
Thank you. Our next question comes from Joe Moore with Morgan Stanley. Your line is now open.
Great. Thank you.
Hey, Joe, are you still there?
Yeah. Can you hear me?
Yeah, now we can. You dropped off for a second there.
Oh, sorry about that. If you could talk about the SSD business in the context of NAND supply, obviously very tight last year. It seems like it's more balanced now, but still pretty healthy. How does that change the mix of hard disk drive versus SSD, and does that have any effect on your market share and your opportunities in that market?
Sure. Yeah. Thanks, Joe. I'll make some high-level commentary. I think, clearly, happy to share some thoughts, but don't want to be the bellwether or the canary in the coal mine on calling NAND supply and demand. I think even some comments last quarter may have gotten construed that way. It wasn't intentional, just trying to be helpful. With that in mind, what I'd say is, probably continued trends and, in terms of what's widely publicized, which is that supply coming online. I think, what I said last quarter sort of ended up coming true and probably will continue. We think that's a good opportunity for us, certainly, as some of the SSD customers we had last year who were supply constrained can now produce and probably get some of, or all of what they need.
As far as the outlook and the impact on HDD, it's something we monitor. That business so far has performed quite well for us. Not only because our end customers have done well, but our sort of increased presence in some of these newer areas for us, like enterprise and nearline have given us a bit of a tailwind there. I guess I'm not in a position or ready to call a bigger picture what's going to happen HDD, SSD, for the year other than we think we see strong growth drivers for us because of our own unique design wins and positioning in both.
We'll, for the time being, stick to our thesis around keep $ flat in HDD, albeit certain quarters will be a little higher, so a little lower, and then keep really executing well on the SSD growth that's out there and try to make it happen. That's the landscape of what I can share at this time.
Okay. That's helpful. Thank you. I wonder also, if you could just touch on your gross margins keep going up. I think it's been a couple of quarters now, you said sort of mix is going against you, but gross margins continue to rise. How should we think about that? Is that just simply mix within each of the segments, and is there anything kind of formulaic we can look at as to how much gross margin falls through as you continue to grow revenues?
Sure. Yeah. No, I actually do think, it's not intentional, obviously, to sound like a broken record on this one, which is, hey, gross margins did better than we thought. Gross margin outlook's better than we thought, but we also have this sort of mix issue going against us. It has been true. Really what's happened is connectivity was just a really strong performer for us last year, it's sort of been that way every quarter. It's done a little bit better than we thought. That being said, we do think because of in the sort of what's been realized so far, absolutely has been improved mix within each of the segments, meaning, we've gotten higher value design wins or new product ramps in storage and networking or in connectivity.
Despite the fact that that business did grow year-over-year, we have been actively remixing quite a bit in that business in terms of letting lower value applications just sort of go away and really focusing on areas where we could make a gross margin impact and really focusing on profitability versus top line. Top line also worked well there. What I'd say is I'd stick to my same story, which is we do think, certainly we gave, I think, a solid guide for Q1, which was 62%-63% on the GM. I don't think anybody a year ago would've been sitting here thinking when we were at Analyst Day 2017, that we'd be talking about guiding 62%-63% a year later. We're really happy with that. Because of the way we've managed the company.
Beyond that, while we don't give specific ranges, our seasonally strong quarters in storage begin in Q2 and Q3. Overall, kind of bigger segment mix should help us there. We'll see. We take it one quarter at a time, but directionally, certainly, we're very pleased. I would also just give a quick shout-out as well to our manufacturing and operations team, who continue to do an outstanding job really working with our supply chain partners and really optimizing our cost structure so we can both grow revenue, reduce costs, and make us more competitive in the market.
Of course, when we combine with Cavium, it will further expand our gross margin. As you recall, when we announced the deal, we did say the combined company target gross margin will be 65%.
Great. Thank you very much.
Thank you. Our next question comes from Blayne Curtis with Barclays. Your line is now open.
Thanks. To my question, I'd like to give congrats on the quarter. I just wanted to follow up on connectivity. Maybe if you could just talk about why the phone and seasonality is an inventory issue or just an earlier build. Then you've telegraphed that mix away from some non-strategic business. Just kind of as you look at this year, is there any kind of lumps in that, or is that kind of a gradual thing as you get new products in, you let some walk out the door? Just want to understand, as this year develops, new business coming in versus the consumer you're walking away from.
Yeah. Hi, Blayne, this is Jean. I'll take the first question about the Q1 guidance. Yeah, when we guided mid-teens sequential increase, it's better than normal seasonality, largely because one particular customer, they are actually building product in Q1 versus typical building Q2, Q3 for holiday season. It's very unusual situation. I do think the Q1 revenue for wireless is unusually high. Q2, Q3, you're actually going to see some kind of a decline more than typical for this particular customer, and which is large customer. That's the dynamics of Q1 versus Q2 and Q3. As far as strategy-wise, overall, we're really trying to focus on profitability of the Wi-Fi business. We're certainly trying to get out some of the low-margin applications more in the consumer side of the business. Matt, you probably can add more on the strategy side.
Sure. Yeah. I think just to reiterate it for all the investors on the call, as I said, we've focused on really profitability in that segment to make sure it's a contributor on certainly gross and on operating margin. We've made huge strides in our wireless business. I think this question you've got, Blayne, about what does that look like as consumer, maybe lower margin or lower value add business rolls off. That's why even in the last year, we've been very judicious every quarter about how we think about that business and guide it because there has been a big remix that's been ongoing and will continue to be ongoing probably over the next year.
As Jean mentioned, because of one of our customers, I think doing a ramp that has some of what would probably be in Q2 and a little bit of Q3 in Q1, that probably linearizes more over, let's say, two and a half quarters versus two quarters. Overall, there's been enough sort of new stuff coming in and old stuff rolling off. Beyond that, I think that's as much as I can be helpful other than we just can't guide Q2, Q3 and beyond in detail just yet.
Thanks. Just on the gross margin, I would think that the wireless business would be a headwind to gross margin. You're still growing it, so maybe just talk about the drivers to gross margin there, though.
Sure. Again, I think we have the headwind issue. We actually guided due to seasonality, obviously, slightly lower revenue. Of course, it was, I think, still a solid guide, but again, very pleased to see on the GM. I think it's as I said, I think we see new products ramping up. If you think about networking, which has been a story we saw in Q4 and we certainly said we're going to see in Q1, those new products have been much higher value and much better margin than historical Marvell legacy or Marvell networking. Also, legacy is lower than the new stuff. As that mix shifts within networking, that's helpful. Again, I'd say it's continued execution on the cost reduction side as well, which has been a benefit to the entire company, to the entire enterprise.
I just reiterate back to what Jean said, when we think about integrating Cavium, all these fundamental improvements with how we manage our supply chain and operations and manufacturing overhead, all that benefit we see is just translating right over as we think about synergies and integrating Cavium. To the extent we're getting improvements in our own margin, not only does that help what will be the blended margin of the combined company, but those structural improvements, we very much think we can pass on to the Cavium side. I just say it's a mix of things, Blayne.
There's no one-trick pony on it in terms of why it's going up other than we've been really focused on it and ultimately, the only way you really do this over time is we believe strongly gross margin is the key indicator of the innovation and the value you're delivering, and the fact that our new products have been ramping strongly across our different segments, it's helping our GMs, and that's the story.
All right. Thank you.
Thank you. For time management reasons, please limit yourselves to one question. Next is Vivek Arya with Bank of America Merrill Lynch. Your line is open.
Thanks for taking my question. Matt, one more on the storage outlook for Q1, down year-on-year. Conceptually, SSD growth should be more sustainably offsetting HDD declines by now. Is there something specific in Q1 that is preventing that? Should we assume that storage starts to regrow year-on-year from Q2 onwards?
Yeah. Vivek, this is Jean. When you look at the Q1 from a seasonal perspective, HDD typically decline actually 7%-10% sequentially. That's really HDD decline much more in Q1. The SSD, we actually is going to see year-over-year growth in Q1. It's just we have a very large base on HDD business. That's why it will not offset in Q1, particularly this decline. As I said, quarter-over-quarter, it may be different. We do expect going forward, especially for the fiscal year, SSD growth is going to be faster than SSD market, which as the market is everybody's consensus now, is over 20%. From that angle, you can see what Matt mentioned earlier is for the fiscal year, we'll largely keep the HDD revenue to be more consistent, flattish for the year and SSD growing much faster than market.
I think the math, quarter-over-quarter, there may be some volatility, but overall, we feel pretty good about the prospect over the future.
Got it. Anything on SSD controller competition? I know you mentioned that, if we set aside competition or insourcing from the customer side, has the competitive landscape with other merchant suppliers changed in any way? You think you still have pretty strong competitive moats in that area?
Sure. No, I think we've certainly had competition in this area for some time. We take nothing for granted. The competitors traditionally we've had over the last couple of years, we still have them. We're still in those battling out on these opportunities. I think the competitive landscape, I wouldn't say has changed, but I would say that as our scale has increased in terms of just the breadth of customers we're supplying, the types of end applications that we're in, which range all the way from consumer and client all the way up to the most advanced hyperscale and enterprise applications in the world. That scale has allowed us to continue to invest in that business, in terms of adding R&D resources and expanding our ability to develop more products and more IP.
We're becoming, I'd say, increasingly more relevant than we were a year and a half ago just because that business scale is now at a point where we have a very comprehensive set of solutions. As I pointed out in my prepared remarks, despite the fact that we've had all this great run, we're still ramping new customers. This past quarter, we ramped a brand-new tier 1 NAND company that we hadn't had before. We ramped also in a new cloud hyperscale application that we weren't in before. That's all new and incremental on top of what we've done. That's what I'd say. I think it's never going to be a pushover between internal competition, merchant, ASIC, which we compete in, as well as some other folks.
Again, from having a breadth of portfolio, scale of revenue and R&D investment, we do believe we have a significant competitive moat there, and we're head and shoulders above the others in the market just because of that scale.
Okay. Thank you.
Thank you. As a reminder, ladies and gentlemen, for time management reasons, please limit yourself to one question. Our next question comes from Ross Seymore with Deutsche Bank. Your line is now open.
Hi, guys. I wanted to go back to the networking side. Matt, I know you've said what the issue was in the fiscal fourth quarter about the pushout, I wanted to think, as you think about it for this year as a whole, I would have thought you'd be a little better than flat in the near-term guide or flat to slightly up if that pushout from last quarter started to help this quarter, given the strength in the end market and some of your big customers. In the near term, can you just talk about what the puts and takes are for the April quarter? As we think through the year, where do you think that legacy business will exit this fiscal 2019 versus where we just exited the prior year? Thanks.
Sure. Maybe I'll take the second part first. Jean, I don't know if you want to comment or we can both do this one together. On the second part, we don't have an exact number, Ross, but I'd say if you sort of went from 20 down to 15, it probably normalizes in that area, right? The 15%-ish that's left is really pretty long lifecycle stuff. While it will decline over time. I think the slope on the downside is kind of moderated. 15% or a little bit lower is kind of the range. In the near term, Jean, I don't know if you want to comment or
Yeah. I think if you are talking about the Q1, right? It's our guidance actually is mid-single digit or high single digit year-over-year growth. It's really primarily driven or led by the switch processor and the PHY portfolio, the refreshed portfolio. The legacy is more likely, we're actually cautious because this component shortage challenge we had last quarter, we're actually very cautious about the legacy side and kept it really at a kind of a sequentially decline kind of way. We'll see how the legacy perform, as Matt said, because this shortage is really not because the market demand, but it's just because of some memory component shortage, we do think later on this year will recover, largely keep the legacy business flattish. It has a long tail.
I would add, too, if you look at the way we phrased it, clearly, Ross, I was certainly disappointed just because, I think overall that networking business really did well for us in Q4, absent this issue, and that's why we're being very sort of specific about calling it out, but it is what it is. If you noticed, what I really said was we expected a recovery in the first half, and that's exactly to back up Jean's point, just being pretty cautious on that one and just not assuming that there's really a bounce back. Normally you have a push out, it was in one quarter, it pushed to the other quarter, and that's when it comes back. I think we've sort of been very thoughtful about that piece of it.
Absent that, I think the rest of it's still working pretty good for us.
The other one certainly is right, is our PHY business actually is quite significant. Most of you guys probably know, PHY business is seasonal, actually it's declining high single digits typically. We actually will be able to offset that seasonal decline of PHY business in Q1. That's another factor. It's a little bit long getting to the details now.
Yeah
That's just dynamics of our networking. We actually have a portfolio for business.
Thank you. Our next question comes from Harlan Sur with J.P. Morgan. Your line is now open.
Good afternoon, congratulations on the solid results. The Marvell team has had great success with Google. I think your ARMADA multi-core processor and your Wi-Fi Bluetooth combo chip powers every Google Home, every Google Home Mini, and Google Home Max product. As we all know, these products have been doing pretty well in the connected home market, and it's a pretty important initiative for Google. The question is this what's driving the strong connectivity growth in the April quarter? How can or how is the team going to leverage its dominance in the connected home part of this customer to potentially gaining more silicon content within the data center segment of their business?
Sure. Well, Harlan, I give you credit for asking a very specific question. As you can probably imagine, and as you've seen sort of from our MO, we prefer to not really get into specific customers and specific content and kind of talk at that level of granular detail. From my days as the sales VP when I was at Maxim, I just learned that customers really don't appreciate it when you start talking about their business, in particular with seasonality things and other things that you're asking. Can't really comment on it other than to say that that particular company is obviously of strategic importance to us, both in that particular product lineup as well as, I would say even of equal or more strategic relevance is obviously becoming a bigger supplier to them in the data center side of their business.
I'll leave it at that. Happy to answer another question, but can't talk about individual customers.
Great. Thanks. Okay. Well, then maybe I'll just follow it up with just a very quick question. Great job on driving the OpEx lower in fiscal year 2018, Jean. How should we think about the OpEx trends beyond the April quarter here in fiscal 2019?
Yeah, that's a good question. I would say the way to think about OpEx is if you look at toward the end of fiscal 2018, our OpEx run rate is around the $208 million per quarter. When you think about the 2019, it's really you have to factor into about 3%-4% inflation, including merit increase, right? $215 million for Q1, that includes the payroll tax, Q2 will have merit increase. I would say it's around this level, for fiscal 2019.
Perfect. Thank you.
Thank you. Our next question comes from Karl Ackerman with Cowen. Your line is now open.
Hi. Clearly hyperscale CapEx is driving not only higher demand for networking, but also storage. I'm curious, do you embrace the view that nearline hard disk drives remain capacity-constrained in the first half of 2018? If so, how is that impacting your ability to both service the hard drive or the HDD vendors as well as receive premium ASPs in this environment?
Appreciate the question. I think though, the best guys to ask would be the companies that we're supplying to. I think that one, they clearly have much more insight than I do, and there's only three of them to ask. I would probably err on that side. With respect to specifics around ASPs and things like that, all we have said historically is at a high level, as we've penetrated into enterprise and nearline and HDD. We certainly have a higher ASP per drive than, say, client, but that's about it. Not in a position to get into specifics about that one or kind of what my end customer's dynamics are going to be in that sort of very specific situation you mentioned, Karl.
Thank you. Our next question comes from Mark Delaney with Goldman Sachs. Your line is now open.
Yes. Good afternoon. Thanks for taking the question. Just hoping to follow up on the comments about distribution. Jean, I think you said it's about 20% of Marvell's revenue currently. I believe at the end of last year, Marvell announced a global distribution agreement with Avnet. Maybe you can help us better understand what you're hoping to achieve in distribution and the reason for the new agreement, and once or if Cavium closes, how are you thinking about using distribution going forward as a combined entity? Thank you.
I'll clarify the percentage of revenue, and then Matt can answer that Avnet question. We have about 20% of our revenue is distribution revenue, but Marvell's distribution revenue, a very large percentage is demand fulfillment. Of course, we are trying to get more demand creation from distributors, but I just want to make sure we understand the numbers first.
You're right, Mark, to note that we did make a change in our distribution network, not only with Avnet, but we made a number of other changes. Really, I would put this one in the bucket of sales force and go-to-market transformation that really Tom Lagatta has been driving since he joined. Soon after he joined, he and I both sat down and just took a look at the global landscape. Given that it's 20% of our business, we quite frankly just had way too many distributors scattered all over the globe. There was not a comprehensive global distribution program. Design registration management was all over the map. The way we were incentivizing those distributors from a margin point of view was not consistent, and I would say we basically had a whole bunch of distributors without a program.
That's why Jean points out it's only 20% of our revenue, and of that, maybe half of it's actually been created from distribution. That, to me, seemed way too low. Tom's reaction was the same. We subsequently added an executive to run distribution, last fall, then before the end of the year, we announced a series of changes, one of which was appointing Avnet as our global distributor and really expanding that franchise worldwide. We terminated a number of others and really got a much more focused channel strategy in place that I think for both sides, both distribution and Marvell, actually optimized the incentive structure and certainly made it much more simple for us from a go-to-market standpoint.
You should expect the same playbook that we've implemented on Marvell, we're going to take a very close look, and already have, with Cavium's distribution network and the activities that they have going on there. By the way, they have some very nice activities going on within distribution and with Cavium. I think there's probably some top-line synergy there to take advantage of that. We're going to put those two together, you should expect we'll have a very professionally managed, efficient global distribution plan implemented as part of our sales track when we think about integrating Cavium.
Thank you. We have time for one more question. Our next question comes from Harsh Kumar with Piper Jaffray. Your line is now open.
Yeah. Hey, guys. Thanks for squeezing me in. Congratulations. First question for you, Matt, is would you be able to give us some sense of how much the preamp revenues are, when they become significant? Given that you're hopefully going to get that revenue to be significant hopefully this year, is it fair to assume that the HDD business could potentially grow in absolute dollars versus your commentary of flattish?
Sure. Just to give you a sense of where that business is at, while we're not dollarizing it at this time, think of it as two years ago, we had no revenue, products in design. Last year, we started shipping in some kind of low volume pre-production drives that were out there. We see this year as a year where we're going to probably see some of those drives go into full volume production, but that would be in the back half, and you should assume that that level of revenue is not significant. It's going to take time because the way that these preamps work is you really design them fairly specifically for an individual customer and an individual drive program. Our strategy has been obviously to try to get those to pair up in applications where we have our own SOC.
That's going to be just kind of an ongoing journey that we'll be on, and we're not breaking out the amounts. Certainly if you talk to my team that runs that entire HDD business, obviously their strategy and plan is to try to-- when I say flat, that's how we're modeling it as a company. Obviously, their plan is to try to grow that business by getting more share, getting more ASP, getting preamps to ramp. It's not like we're trying to limit ourselves there, but we will kind of stick by our models that we indicated earlier in the call, which is preamp ramping is one of the aspects that allows us to keep HDD "flat" over the year. We're not really able to get into the numbers.
As we make progress, you should assume, just like everything we've been doing, we'll be more transparent. We'll give you more details once it's more in front of us. I think I've been served well by not trying to project too far out on new ramps. I think at the end of the day, it's very hard to do that accurately, and I wouldn't want you to over or underestimate too much. I think HDD flat's probably a good way to think of it with preamps being part of the equation.
Thank you. Now I would like to turn the call back over to Peter Andrew for further remarks.
Okay. Well, thank you everyone for joining us today, and we look forward to talking again next quarter. Thank you. Good evening.
Ladies and gentlemen, thank you for your participation in today's conference. This concludes the program. You may now disconnect. Everyone, have a great day.
